The 25kg open-mouth bag packaging machine can accurately control the packaging weight of fertilizers according to user requirements, ensuring that each bag of fertilizer meets national standards and industry norms. At the same time, it can also print production date, batch number, fertilizer content, etc. on the packaging bag to facilitate traceability and management.

V. Working Principle

1. Feeding Mechanism

The feeding mechanism is the first part of the entire packaging process. According to the physical properties and flow characteristics of different materials, appropriate feeding methods and devices are selected. For example, for powdery materials with good fluidity, a gravity feeder or a vibrating feeder can be used to make the material enter the weighing hopper evenly through the vibration or gravity action of the feeder. For granular materials with poor fluidity, a pneumatic conveyor can be used to convey the material to the packaging position through the action of airflow. Some materials with special properties may need to be equipped with additional auxiliary devices (such as vibration leveling devices) during the feeding process to ensure smooth feeding.

2. Weighing Mechanism

The weighing mechanism is the core part that ensures accurate packaging weight. It usually consists of a weighing sensor (such as a strain gauge sensor), a weighing hopper, and an A/D converter. When the material enters the weighing hopper, the pressure signal generated by the weight of the material is converted into an electrical signal by the weighing sensor and transmitted to the A/D converter. The A/D converter converts the analog electrical signal into a digital signal that can be processed by a microprocessor (such as a microcontroller). The microprocessor calculates the actual weight of the material in real-time based on the preset target weight and controls the opening and closing of the feeding gate to adjust the amount of material entering the weighing hopper until the actual weight matches the preset weight. To ensure weighing accuracy, the weighing system needs to be regularly calibrated using standard weights or other calibration tools to eliminate errors caused by factors such as sensor zero drift and sensitivity changes.

3. Bag Clamping Mechanism

After completing the weighing process, the full weighing hopper opens the bottom door through a control signal, allowing the material to fall into the waiting open-mouth bag below. At this time, the bag clamping mechanism comes into play. The bag clamping mechanism usually consists of a pair of symmetrical clamping plates driven by a cylinder or an electric motor. When the material starts to fall into the bag, the clamping plates move towards each other under the drive of the cylinder or electric motor to clamp the bag mouth tightly. The clamping height of the clamping plates can be adjusted according to the size of the bag to adapt to different specifications of open-mouth bags. During the clamping process, some bag clamping mechanisms are also equipped with position detection devices to ensure accurate clamping of the bag mouth and prevent deviation during clamping.

VI. Operation Steps

1. Start Preparation

(1) Ensure that the power supply of the machine is connected correctly and the grounding is good. Turn on the power switch of the machine and wait for it to start normally. Check whether there is an abnormal sound or smell during startup. If any abnormalities are found, stop the machine immediately for troubleshooting. (2) Place the pre-made open-mouth bag on the bag loading platform of the machine and adjust its position so that the bag mouth aligns with the clamping position of the clamping mechanism. Make sure the bag is placed flat without wrinkles or twists. (3) According to the type and packaging requirements of the material to be packed, set relevant parameters on the control panel of the machine, such as target weight, packaging speed, sealing temperature (for thermal sealing), etc. Ensure that all parameter settings are correct before starting packaging. (4) Check whether there is enough material in the material warehouse and whether the material feeding device works properly. If necessary, add sufficient material to ensure continuous production during the packaging process.

2. Packaging Process

(1) Start the feeding device to feed the material into the weighing hopper according to the set parameters. During the feeding process, observe whether the material falls into the weighing hopper evenly without jamming or overflow phenomena. If there is any abnormality, adjust the feeding speed or feeding mode in time. (2) When the material in the weighing hopper reaches the preset weight, the weighing system sends a stop signal to close the feeding gate to stop feeding. Then, control signals are sent to open the bottom door of the weighing hopper to allow the material to fall into the open-mouth bag below freely. During this process, pay attention to controlling the falling speed to avoid dust splash or material spillage. (3) After the material falls into the bag, start the clamping mechanism to clamp the bag mouth tightly. The clamping mechanism drives the clamping plates to move towards each other under the action of a cylinder or an electric motor to ensure that the bag mouth is sealed reliably without leakage. During the clamping process, check whether the clamping position is accurate and whether there is any damage to the bag due to improper clamping. (4) After clamping is completed, if there is a sealing process, activate the sealing device according to the preset sealing method (such as heating elements for heat sealing). The sealing device generates heat or pressure to seal the bag mouth firmly. The temperature and time parameters during the sealing process must be strictly controlled to ensure sealing quality. After sealing is completed, let it cool down for a while before proceeding to unloading. (5) After unloading a bag, reset related mechanisms (such as retracting the clamping plates) to prepare for the next packaging cycle. At this time, check whether there is residual material in the weighing hopper or on other parts of the machine. If there is residual material, clean it up in time to avoid affecting subsequent packaging work.

VII. Maintenance and Care

1. Daily Maintenance

(1) Cleanliness Maintenance: After each working day ends or before starting production on the next day, clean up residues and dust on the surface of the machine. Use a soft cloth dipped in a neutral detergent solution to wipe down areas where materials come into contact with each other, such as the feeding port, weighing hopper, clamping mechanism, etc. Avoid using sharp tools or corrosive cleaning agents that may scratch or damage machine parts. For parts that are not easily cleaned (such as corners inside the weighing hopper), use a small brush or air nozzle for cleaning. After cleaning, wipe dry with a clean cloth to prevent rust caused by water渍残留. (2) Lubrication Maintenance: Check the lubrication condition of moving parts (such as gears, chains, guide rails). According to the requirements of the manual, add lubricating oil or grease of appropriate amount and type to each lubrication point regularly. Make sure that each lubrication point gets adequate lubrication without excessive or omitted lubrication. Lubricated parts should be wiped clean of excess lubricant to prevent oil渍污染其他部位。 (3) Tightening Loose Parts: Due to vibration during operation, some screws and nuts on the machine may become loose over time. Check key parts such as fasteners on the feeding mechanism, weighing mechanism, and clamping mechanism regularly (recommended once a week). Use appropriate tools (such as wrenches) to tighten any loose screws or nuts to ensure that all parts are securely connected and operate normally. During tightening, do not over-tighten to avoid damaging threads or causing parts deformation. (4) Check Electrical Systems: Check whether electrical wirings are aging, damaged or loose regularly (recommended once a month). Ensure that wire connectors are secure and that there is no exposure of wire cores. Check whether grounding is good to ensure electrical safety. If there are any damaged or aging wires, replace them in time according to electrical safety standards. Also, check whether electrical components (such as switches, relays) are working properly and replace any faulty components promptly. (5) Functional Testing: Perform simple functional tests on major mechanisms of the machine every day before starting production (such as feeding action test, weighing accuracy test, clamping mechanism opening and closing test). Through these tests, it can be quickly determined whether each mechanism is working properly. If any abnormality is found in the test, stop production immediately for troubleshooting and repair to avoid affecting production efficiency due to machine failure during formal production.

2. Periodic Maintenance (Recommended Every Three Months)

(1) Cleaning and Inspection: Thoroughly clean internal components of the machine (such as material warehouse, weighing hopper interior) and inspect whether there is material accumulation or blockage in each component. Clean accumulated material from hard-to-reach corners using specialized tools (such as vacuum cleaners). Check whether there is wear or damage on parts that are prone to wear (such as feeding screw blades, sealing heads). If minor wear is found, repair or replace parts in time to extend their service life. For severely worn parts (such as sealing heads with serious abrasion), consider replacing with new spare parts directly. (2) Calibration and Adjustment: Recalibrate the weighing system using high-precision standard weights or other calibration tools to ensure weighing accuracy meets requirements. Adjust parameters related to sealing temperature (for heat sealing), sealing time, clamping pressure, etc. according to actual production conditions and material characteristics to ensure optimal sealing effect and stable operation of each mechanism. Record calibration data and adjustment parameters for future reference and comparison. (3) Full Function Testing: Conduct a comprehensive functional test on all aspects of the machine's operation (including various automatic cycles from feeding to sealing). Simulate different production scenarios (such as different material types and weights) to check whether all mechanisms cooperate seamlessly and whether there are any potential problems (such as unstable feeding speed affecting weighing accuracy). During the test, carefully observe whether there are any abnormal phenomena (such as unusual noise or vibration) and record them for subsequent analysis and troubleshooting.
