Description

Technical Field

[0001] This utility model belongs to the field of paste filling technology, specifically relating to a paste filling device. Background Technology

[0002] In modern industrial production, paste filling equipment is widely used in fields such as cosmetics to accurately fill paste-like materials into containers. With the continuous growth of market demand, higher requirements are being placed on the efficiency and accuracy of paste filling. However, existing paste filling equipment still has many shortcomings in practical applications.

[0003] Traditional filling equipment often uses a fixed structure, making it difficult to adjust the position of the filling head and adapt to the filling needs of different container sizes, resulting in poor equipment versatility. Furthermore, existing equipment frequently experiences uneven filling volumes during the filling process due to differences in material flowability or unstable filling pressure, affecting product quality and consistency.

[0004] Meanwhile, some equipment lacks an efficient conveying and positioning system, making containers prone to shifting or tipping during transport, further reducing filling accuracy and production efficiency. To address these issues, there is an urgent need to design a paste filling device with a reasonable structure, convenient operation, and the ability to achieve efficient and precise filling, in order to meet the demands of modern production and improve overall operational efficiency. Summary of the Invention

[0005] In view of the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a paste filling device that is reasonably structured, easy to operate, and capable of achieving efficient and accurate filling.

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A paste filling device includes a worktable, a filling structure, and a plate chain conveyor. The worktable serves as the foundation platform for the entire device, with a support column fixedly mounted on one side of its top and a plate chain conveyor on the other side. A mounting plate is connected to the top of the support column, and a pneumatic push rod is mounted on the top of the mounting plate. The filling structure is located on top of the plate chain conveyor, and the output end of the pneumatic push rod passes through the mounting plate and connects to the filling structure, driving the filling structure to move vertically, thereby achieving automated paste filling.

[0007] Based on the above scheme and as a preferred embodiment, the injection structure includes a tripod. An upper guide plate and a lower guide plate are connected to the top and bottom of the back of the tripod, respectively. Both the upper and lower guide plates are fitted onto the support column, and a sliding fit enables the injection structure to move linearly up and down. A clearance fit is provided between the inner holes of the upper and lower guide plates and the support column to ensure that the injection structure does not shift during movement. Simultaneously, increasing the guide area reduces friction and improves the stability of the movement.

[0008] Based on the above scheme and as a preferred embodiment: a chute is provided at the bottom of the tripod on the side away from the support column, and hangers are evenly spaced at the bottom of the chute. The top of the hangers passes through the chute and is threadedly connected with nuts. The height of the hangers is adjusted by rotating the nuts; after loosening the nuts, the hangers can be moved horizontally along the chute to accommodate the filling needs of containers of different sizes. A filling device is installed at the bottom of the hangers, and the discharge end of the filling device is aligned with the container opening on the plate chain conveyor to complete the precise filling of the paste.

[0009] Based on the above scheme and as a preferred embodiment: An interface for connecting a grouting pump is provided on one side of the injector, and the grouting pump delivers the paste into the injector through a pipeline. The injector is equipped with a flow control valve, which is opened and closed by electromagnetic drive to control the discharge rate of the paste. The discharge end at the bottom of the injector is designed with a conical structure, the diameter of the tip of the cone being slightly smaller than the diameter of the container opening, to reduce overflow or leakage of the paste during the filling process.

[0010] Based on the above scheme and as a preferred embodiment: The top sides of the plate chain conveyor are equipped with baffles mounted on screws. The spacing between the baffles is adjustable to accommodate containers of different widths. An elastic pad, made of rubber, is provided on the inner side of the baffles to prevent damage to the containers due to collisions during transport. The plate chain conveyor is driven by a motor, and multiple positioning blocks are installed on the chain. The spacing between the positioning blocks matches the length of the container to ensure that the container maintains a fixed position during transport.

[0011] Based on the above scheme and as a preferred embodiment: the output end of the pneumatic actuator is connected to the injection structure via a flange. The flange has multiple mounting holes into which high-strength bolts are embedded to enhance the connection strength. The stroke range of the pneumatic actuator is controlled by a limit switch on the mounting plate. The limit switch is connected to a controller via a signal line. The controller adjusts the extension and retraction length of the pneumatic actuator according to a preset program, thereby achieving precise positioning of the injection structure.

[0012] Based on the above scheme and as a preferred option: the outer surface of the support column is hardened to a hardness of HRC50 or higher to improve its wear resistance. The top of the support column is fixed to the mounting plate by welding, and the weld seam is ground to ensure a smooth and flat connection. The mounting plate is 15mm to 20mm thick and made of carbon steel to ensure sufficient rigidity and load-bearing capacity.

[0013] Based on the above scheme and as a preferred option: the operating speed of the plate chain conveyor is regulated by a frequency converter. The frequency converter adjusts the motor speed by receiving signals from the controller, thereby changing the operating speed of the conveyor. The chain of the plate chain conveyor is made of stainless steel with a chain pitch of 38.1mm, which can withstand large tensile forces and has good corrosion resistance.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are: This invention relates to a paste filling device. Compared with existing technologies, it utilizes a pneumatic pusher to drive the filling structure up and down along a support column, combined with the continuous conveying function of a plate chain conveyor, achieving fully automated paste filling and significantly improving production efficiency. The filling structure, through the cooperation of the upper and lower guide plates with the support column, ensures the stability of the filling device during its vertical movement. Simultaneously, the lifting rod can be finely adjusted in height and position via a sliding groove and nut, thus achieving precise filling. The number and position of the filling devices can be flexibly adjusted according to actual needs, making it suitable for filling containers of different specifications and types.

[0015] The combined design of support columns, mounting plates, and tripods ensures the structural strength and stability of the entire device, effectively preventing errors caused by vibration or displacement during the filling process. The baffles on both sides of the plate chain conveyor simplify container positioning and conveying operations, reducing the need for manual intervention.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments; This embodiment provides a paste filling device, including a workbench 1, a filling structure 2, and a plate chain conveyor 3. The workbench 1 serves as the foundation platform for the entire device, with a support column 11 fixedly installed on one side of its top and a plate chain conveyor 3 installed on the other side. A mounting plate 12 is connected to the top of the support column 11, and a pneumatic push rod 13 is mounted on the top of the mounting plate 12. The output end of the pneumatic push rod 13 passes through the mounting plate 12 and connects to the filling structure 2, driving the filling structure 2 to move vertically, thereby achieving automated paste filling. In practical applications, the workbench 1 is made of 20mm thick carbon steel plate with a rust-proof surface treatment to ensure sufficient strength and corrosion resistance to meet the requirements of long-term continuous operation.

[0019] The core component of the injection structure 2 is the tripod 21. The top and bottom of the back of the tripod 21 are respectively connected to an upper guide plate 22 and a lower guide plate 23. Both the upper guide plate 22 and the lower guide plate 23 are fitted onto the support column 11, and a sliding fit enables the linear movement of the injection structure 2 during its up-and-down movement. The inner holes of the upper guide plate 22 and the lower guide plate 23 are fitted with a clearance fit to the support column 11, with the clearance range controlled between 0.1mm and 0.2mm. This ensures that the injection structure 2 will not shift during movement and also reduces friction by increasing the guide area, thus improving the stability of the movement. In actual production, the tripod 21 is made of aluminum alloy, and after anodizing treatment, the surface hardness reaches HRC40 or higher, enabling it to withstand large dynamic loads while reducing overall weight and facilitating maintenance and adjustment.

[0020] Furthermore, a groove 24 is provided at the bottom of the tripod 21 on the side away from the support column 11, and hanging rods 25 are evenly spaced at the bottom of the groove 24. The top of the hanging rods 25 passes through the groove 24 and is threadedly connected by nuts 27. The height of the hanging rods 25 can be adjusted by rotating the nuts 27. After loosening the nuts 27, the hanging rods 25 can move horizontally along the groove 24 to adapt to the filling needs of containers of different sizes. A filling device 26 is installed at the bottom of the hanging rods 25. The discharge end of the filling device 26 is aligned with the container opening on the plate chain conveyor 3 to complete the precise filling of the paste. The design of the filling device 26 is particularly critical. It has a flow control valve inside, which is opened and closed by electromagnetic drive to control the discharge volume of the paste. The discharge end of the filling device 26 is designed with a conical structure. The diameter of the tip of the conical structure is slightly smaller than the diameter of the container opening to reduce the overflow or dripping of the paste during the filling process. In addition, one side of the injector 26 is provided with an interface for connecting a grouting pump. The grouting pump delivers paste into the injector 26 through a pipeline to ensure the continuity and stability of the filling process.

[0021] Furthermore, the top sides of the plate chain conveyor 3 are equipped with baffles 31 via screws. The spacing between the baffles 31 can be adjusted according to the width of the container to accommodate different sizes. An elastic pad, made of rubber and 3mm to 5mm thick, is provided on the inner side of each baffle 31 to prevent damage to the container during transport due to collisions. The plate chain conveyor 3 is driven by a motor. The chain is made of stainless steel with a pitch of 38.1mm, capable of withstanding significant tensile force and possessing excellent corrosion resistance. Multiple positioning blocks are installed on the chain, with the spacing between them matching the length of the container to ensure the container remains in a fixed position during transport, preventing a decrease in filling accuracy due to shaking.

[0022] Furthermore, the output end of the pneumatic push rod 13 is connected to the injection structure 2 via a flange. The flange has multiple mounting holes into which high-strength bolts are embedded to enhance the connection strength. The stroke range of the pneumatic push rod 13 is controlled by a limit switch on the mounting plate 12. The limit switch is connected to the controller via a signal line. The controller adjusts the extension and retraction length of the pneumatic push rod 13 according to a preset program, thereby achieving precise positioning of the injection structure 2. In actual operation, the controller adopts a PLC programming control system. Users can set the stroke parameters of the pneumatic push rod 13 and the running speed of the plate chain conveyor 3 through a touch screen interface to meet the needs of different production tasks.

[0023] Furthermore, the outer surface of the support column 11 is hardened to a hardness of HRC50 or higher to improve its wear resistance. The top of the support column 11 is fixed to the mounting plate 12 by welding, and the weld seam is ground to ensure a smooth and flat connection. The mounting plate 12 is 15mm to 20mm thick and made of carbon steel to ensure sufficient rigidity and load-bearing capacity. The surface of the mounting plate 12 is sandblasted and then coated with an anti-corrosion coating to extend its service life.

[0024] Furthermore, the operating speed of the plate chain conveyor 3 is regulated by a frequency converter. The frequency converter adjusts the motor speed by receiving signals from the controller, thereby changing the conveyor's operating speed. In practical applications, the frequency range of the frequency converter is set from 10Hz to 50Hz, corresponding to a conveying speed of 0.5m / min to 2.5m / min, which can meet the rhythm requirements of different production lines. The chain of the plate chain conveyor 3 adopts a modular design, with each chain section connected by pins, facilitating disassembly and maintenance. The surface of the chain is polished to reduce frictional resistance during operation and improve transmission efficiency.

[0025] In operation, the container to be filled is first placed on the chain of the plate chain conveyor 3, and its position is fixed by positioning blocks. The plate chain conveyor 3 is then started, and the container moves with the chain to below the filling device 26. At this point, the controller sends a signal, and the pneumatic pusher 13 pushes the filling structure 2 downwards along the support column 11 until the discharge end of the filling device 26 approaches the container opening. The grout pump delivers the paste into the filling device 26 through a pipeline, and the flow control valve opens according to preset parameters, allowing the paste to flow out from the discharge end of the filling device 26 and into the container. After filling is complete, the flow control valve closes, the pneumatic pusher 13 pulls the filling structure 2 upwards to reset, and the plate chain conveyor 3 continues to operate, transporting the filled container to the next process.

[0026] In practical applications, such as sauce filling production lines in the food industry, this device can achieve a high-efficiency production rate of 20 to 30 containers per minute. For ointment filling in the pharmaceutical industry, the filling accuracy can be controlled within ±0.5g, meeting high production standards. In the cosmetics industry, this device is suitable for filling lotions, creams, and other cream-based products. By adjusting the height and position of the 25mm boom, it can accommodate bottles of different sizes, significantly improving the flexibility and adaptability of the production line.

[0027] In summary, this invention achieves fully automated paste filling by using a pneumatic push rod 13 to drive the filling structure 2 to move up and down along the support column 11, combined with the continuous conveying function of the plate chain conveyor 3, significantly improving production efficiency. The filling structure 2, through the cooperation of the upper guide plate 22 and lower guide plate 23 with the support column 11, ensures the stability of the filling device 26 during its up-and-down movement. Simultaneously, the hanging rod 25 can be finely adjusted in height and position via the slide groove 24 and nut 27, thus achieving precise filling. The number and position of the filling devices 26 can be flexibly adjusted according to actual needs, suitable for filling containers of different specifications and types. The combined design of the support column 11, mounting plate 12, and tripod 21 ensures the structural strength and stability of the entire device, effectively avoiding errors caused by vibration or offset during the filling process. The baffles 31 on both sides of the plate chain conveyor 3 simplify container positioning and conveying operations, reducing the need for manual intervention.
