55 Gallon Chemical Filling System for Automatic Glue Applications

I. Basic Components

1. Feeding System

   • Liquid Storage Tank: It is usually made of stainless steel, such as type 304 or 316 stainless steel, to ensure the safety and corrosion resistance of the stored liquid. With a capacity of 200L, it can meet the production needs of a certain scale. The liquid storage tank is connected to the inlet of the filling system through pipes, providing a stable source of liquid for the entire filling process.
   • Feed Pump: It is responsible for transporting the liquid from the storage tank to the filling position. Corrosion-resistant, stable flow, and suitable lift centrifugal pumps or gear pumps are usually selected to ensure that the liquid can flow into the filling head stably.

2. Filling System

   • Filling Head: As the key component that comes into direct contact with the container for liquid filling, the filling head is usually equipped with a high-precision flowmeter and control valve to ensure the high accuracy and stability of the filling volume. There are various designs for the filling head. For example, the anti-drip design can prevent liquid dripping during the filling process; the anti-foaming design can prevent the generation of bubbles in the liquid during the filling process, thereby affecting the filling accuracy.
   • Metering Device: There are two common types of metering devices: flowmeters and weighing sensors. The flowmeter determines the filling volume by measuring the volume of the liquid and is suitable for most liquids with good fluidity; the weighing sensor determines the filling volume by measuring the weight of the liquid and is more applicable for liquids with high viscosity or extremely high filling accuracy requirements.

3. Container Conveying System

   • Conveyor Belt: It is used to transport empty containers and filled containers to their respective positions. It is usually made of wear-resistant and corrosion-resistant materials, such as rubber or plastic, to prevent damage to the containers during transportation. The speed of the conveyor belt can be flexibly adjusted according to actual production needs, so as to ensure synchronous operation with the filling system.
   • Positioning Device: This device can accurately position the containers at the filling position, effectively preventing the containers from shifting or moving during the filling process, and ensuring the accuracy and stability of filling.

4. Control System

   • PLC Programmable Controller: As the core control component of the entire filling machine, it is responsible for receiving and processing signals from various sensors and precisely controlling the actions of each actuator according to preset programs. The PLC has the advantages of high reliability, strong anti-interference ability, and flexible programming. It can be programmed and adjusted according to different production needs to achieve the best filling effect.
   • Touch Screen Man-Machine Interface: Operators can easily set various parameters through the touch screen, such as filling volume, filling speed, start and stop of equipment, and also monitor the operating status and fault information of the equipment in real time, making the operation more intuitive, convenient, and greatly improving the operability and intelligence level of the equipment.

5. Sealing System

   • Capping Machine: It is mainly used to put lids on filled containers and ensure that the lids are tightly sealed. The capping machine usually adopts pneumatic or electric driving modes and places the lids accurately on the containers through mechanical hands or rotating mechanisms, and performs pressurization or tightening operations to ensure good sealing of the containers.
   • Pressure Cap Device: For some containers that need to be sealed under pressure, a special pressure cap device will also be equipped. This device can apply a certain amount of pressure to the container lids through hydraulic or pneumatic systems to make them fit tightly with the container mouths and effectively prevent liquid leakage.

6. Coding System

   • Coding Machine: In order to facilitate product traceability and management, the coding machine can automatically print production dates, batch numbers, product models, and other information on the surface of the containers, making it easy for users to identify and manage products.

II. Working Principle

1. Preparation: Before starting the filling machine, carefully check whether all components are normal to ensure that the feeding system, filling system, conveying system, and control system are ready. Meanwhile, prepare a sufficient number of empty containers and place them neatly in the designated position.

2. Transportation and Positioning: After starting the conveying system, empty containers will be smoothly transported to the filling position by the conveyor belt. At this time, the positioning device will automatically come into play, accurately positioning the containers directly below the filling heads to ensure that the containers do not shift or move during the filling process.

3. Peeling and Filling: When the control system receives the filling signal, the liquid in the feeding system will flow into the metering device of the filling head under the action of the feed pump through pipes. Before starting to fill, the metering device will automatically carry out the peeling operation, that is, deduct the weight of the container itself, in order to ensure the accuracy of the filling volume. When the preset filling volume is reached, the control system will promptly issue an instruction to close the valve of the filling head and stop filling.

4. Sealing and Coding: After the filling is completed, the conveying system will transport the filled containers to the sealing position. Here, the capping machine or pressure cap device will seal the containers to ensure tight sealing of the lids. Subsequently, the coding machine will print relevant information on the surface of the containers.

5. Finished Product Output: After sealing and coding are completed, the conveying system will play a role again and transport the filled containers to the finished product area for further processing or transportation.

III. Performance Characteristics

1. High Efficiency and High Yield: It can quickly and continuously complete the filling work of large quantities of liquid, significantly improving production efficiency, reducing labor costs, and bringing greater economic benefits to enterprises.

2. High Precision: Using advanced metering technology and control system, it can ensure that the filling volume error of each container is controlled within a minimal range, meeting the strict requirements of quantitative packaging in the liquid packaging industry and ensuring product quality stability.

3. Safety and Reliability: The equipment has multiple safety protection measures, such as overload protection, leakage protection, explosion-proof design (for flammable and explosive liquids), etc., which can effectively guarantee the personal safety of operators and the stable operation of equipment and reduce the accident rate.

4. Strong Adaptability: It can flexibly adjust the filling parameters and process flow according to the characteristics of different liquids and production needs, and is suitable for filling liquids with various viscosities and corrosiveness, having strong universality and flexibility.

5. Easy Maintenance: The overall structure is designed reasonably, and each component is easy to disassemble and install, facilitating daily cleaning, maintenance, and repair work. Moreover, the high degree of automation of the equipment reduces long-term usage costs.
