Description

Technical Field

[0001] This utility model relates to the field of premixing device technology, and in particular to a pre-coated film adhesive premixing device. Background Technology

[0002] In modern industrial production, pre-coated film adhesive premixing equipment plays a crucial role and is widely used in packaging, printing, and other fields. Pre-coated film is a composite material in which adhesive is pre-coated onto a thin film and then bonded to the surface of paper or other materials by hot pressing. The adhesive premixing process has a decisive impact on the quality and performance of the pre-coated film, directly affecting the bonding strength, flatness, and appearance of subsequent products.

[0003] Most pre-coated film adhesive premixing devices on the market currently employ fixed-mount mixing blades on a mixing shaft in their material mixing section. The mixing shaft is driven by a motor for a single rotational motion. The mixing blades are typically simple paddle shapes, moving in a circular motion around the center of the mixing shaft. After the material enters the mixing zone, it is mainly mixed within the mixing container by the shearing and pushing forces generated by the rotation of the mixing blades. As the material enters through the inlet, it forms a ring-shaped or spiral flow path within the container, achieving initial mixing, as the mixing blades rotate.

[0004] However, this traditional mixing method has certain shortcomings. The mixing range of the equipment is relatively limited. The mixing blades only move in a planar circular motion around the mixing shaft, resulting in uneven mixing of materials in the vertical direction of the mixing container. Materials at the bottom and top of the container cannot fully participate in the mixing, leading to poor overall mixing effect. Moreover, this single mixing method results in a long mixing time, which greatly reduces production efficiency, fails to meet the needs of enterprises for high-efficiency production, and increases production costs. Therefore, a pre-coated film adhesive premixing device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pre-coated film adhesive premixing device, which aims to improve the problem that the equipment has a relatively limited range of material mixing and requires a long time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pre-coated film adhesive premixing device includes a mixing tank, a feed pipe fixedly connected to the top of the mixing tank, a discharge pipe fixedly connected to the bottom of the mixing tank, and a stirring assembly and a cleaning assembly disposed inside the mixing tank.

[0008] The stirring assembly includes multiple stirring blades located inside the mixing tank. A second fixing frame is fixedly connected to the bottom of the mixing tank. A second motor is fixedly connected inside the second fixing frame. A first connecting plate is fixedly connected to the output end of the second motor. A connecting column and multiple sliding columns are fixedly connected to the top of the first connecting plate. The sliding columns are located on both sides of the connecting column. A rotating shaft is slidably connected to the outer walls of the connecting column and the sliding columns. The outer wall of the rotating shaft is fixedly connected to one side of the stirring blade. Each stirring blade has a guide hole inside. A fixing column is slidably connected to the top of the rotating shaft. A sliding groove is opened inside the fixing column. Slider blocks are fixedly connected to both sides inside the rotating shaft. The sliders are slidably connected to the inner wall of the sliding groove.

[0009] As a further description of the above technical solution:

[0010] A fixing frame is fixedly connected to the outer wall of the fixing column, and the outer wall of the fixing frame is fixedly connected to the inner wall of the mixing tank. Multiple support feet are fixedly connected to the bottom of the mixing tank.

[0011] As a further description of the above technical solution:

[0012] A spring is installed inside the rotating shaft. One end of the spring is fixedly connected to a connecting disc two, and the other end of the spring is fixedly connected to the inner wall of the rotating shaft. A ball is rotatably connected inside the connecting disc two, and the ball is in contact with the connecting column.

[0013] As a further description of the above technical solution:

[0014] The cleaning assembly includes multiple nozzles located inside the mixing tank, and a motor is fixedly connected to the top of the mixing tank.

[0015] As a further description of the above technical solution:

[0016] One output end of the motor is fixedly connected to a limiting plate, and a connecting pipe is fixedly connected to the bottom of the limiting plate.

[0017] As a further description of the above technical solution:

[0018] The limiting plate and the outer wall of the connecting pipe are rotatably connected to a support frame, and the outer wall of the support frame is fixedly connected to the inner wall of the mixing tank.

[0019] As a further description of the above technical solution:

[0020] A water pipe is fixedly connected inside the mixing tank. One end of the water pipe is fixedly connected inside the support frame. Multiple holes are opened inside the connecting pipe to guide water from inside the water pipe into the nozzle.

[0021] As a further description of the above technical solution:

[0022] Multiple connecting blocks are fixedly connected to the outer wall of the connecting pipe, and the bottom of the connecting blocks is fixedly connected to the top of the nozzle.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the stirring blade is driven to rotate by a motor, and the material flow speed is accelerated by the guide hole. At the same time, the slider slides on the inner wall of the chute, so that the stirring blade moves up and down while rotating, thereby achieving the effect of stirring the material. This solves the problem that the equipment has a relatively limited stirring range and requires a long time, and improves the stirring efficiency of the equipment.

[0025] 2. In this utility model, water from inside the water pipe is sprayed onto the inner wall of the mixing tank through a nozzle. At the same time, the nozzle is driven to rotate by a motor, and a limiting plate provides support for the rotation of the nozzle. Centrifugal force is used to expand the spraying range of the nozzle, achieving comprehensive rinsing of the inner wall of the mixing tank. This solves the problem of the water flow spraying range on the inner wall of the equipment being relatively limited, which easily leads to dead corners in rinsing, and enhances the cleaning effect inside the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The present invention provides an embodiment of a pre-coated film adhesive premixing device, comprising a mixing tank 1, a feed pipe 2 fixedly connected to the top of the mixing tank 1, a discharge pipe 3 fixedly connected to the bottom of the mixing tank 1, and a stirring assembly and a cleaning assembly provided inside the mixing tank 1.

[0035] The mixing assembly includes multiple stirring blades 24, which are located inside the mixing tank 1. A second fixing frame 13 is fixedly connected to the bottom of the mixing tank 1. A second motor 14 is fixedly connected inside the second fixing frame 13. A first connecting plate 15 is fixedly connected to the output end of the second motor 14. A connecting column 16 and multiple sliding columns 17 are fixedly connected to the top of the first connecting plate 15. The sliding columns 17 are located on both sides of the connecting column 16. A rotating shaft 20 is slidably connected to the outer wall of the connecting column 16 and the sliding columns 17. The outer wall of the rotating shaft 20 is fixedly connected to one side of the stirring blade 24. Each stirring blade 24 has a guide hole 25 inside. A fixed shaft 20 is slidably connected to the top of the rotating shaft 20. The fixed column 21 has a groove 22 inside. The rotating shaft 20 has sliders 23 fixedly connected to both sides inside. The sliders 23 are slidably connected to the inner wall of the groove 22. The fixed column 21 has a fixed bracket 12 fixedly connected to the outer wall. The outer wall of the fixed bracket 12 is fixedly connected to the inner wall of the mixing tank 1. The bottom of the mixing tank 1 has multiple support feet 4 fixedly connected. The rotating shaft 20 has a spring 18 inside. One end of the spring 18 is fixedly connected to a connecting plate 29. The other end of the spring 18 is fixedly connected to the inner wall of the rotating shaft 20. The connecting plate 29 has a rotatably connected ball 26. The ball 26 is in contact with the connecting column 16.

[0036] Specifically, during the use of the equipment, the material is first poured into the mixing tank 1 through the feed pipe 2. Then, the motor 2 14 is started. The output end of the motor 2 14 drives the connecting column 16 and the sliding column 17 on the outer wall of the connecting plate 15 to rotate. During the rotation of the sliding column 17, the rotating shaft 20, the stirring blade 24, and the guide hole 25 rotate together. Through the rotation of the stirring blade 24, the material inside the mixing tank 1 is fully stirred. During this process, the narrow space inside the guide hole 25 effectively affects the dynamic behavior of the fluid according to Bernoulli's principle, achieving ideal fluid steady flow. In dynamic conditions, areas with high flow velocity within the same flow tube have lower pressure, while areas with low flow velocity have higher pressure. When liquid flows through an area with holes, the cross-sectional area of ​​the flow channel at the holes becomes smaller, leading to an increase in flow velocity and a decrease in pressure. Simultaneously, the pressure of the surrounding liquid is relatively high. Under the influence of this pressure difference, the liquid is pushed towards the holes, accelerating the flow. Meanwhile, the rotation of the shaft 20 causes the slider 23 to slide along the inner wall of the groove 22. During this movement, the connecting column 16, through the cooperation of the ball 26 and the connecting disc 19, compresses the spring 18. The rebound of the spring 18 then guides the slider 23 to slide along the inner wall of the groove 22, causing the stirring blades 24 on the outer wall of the shaft 20 to reciprocate up and down while rotating. This design greatly expands the stirring range of the equipment and significantly improves the stirring efficiency of the material.

[0037] Reference Figure 1 - Figure 3 The cleaning assembly includes multiple nozzles 10, which are located inside the mixing tank 1. A motor 6 is fixedly connected to the top of the mixing tank 1. A limiting plate 11 is fixedly connected to the output end of the motor 6. A connecting pipe 8 is fixedly connected to the bottom of the limiting plate 11. A support frame 7 is rotatably connected to the outer wall of the limiting plate 11 and the connecting pipe 8. The outer wall of the support frame 7 is fixedly connected to the inner wall of the mixing tank 1. A water pipe 5 is fixedly connected inside the mixing tank 1. One end of the water pipe 5 is fixedly connected to the inside of the support frame 7. Multiple holes are opened inside the connecting pipe 8 to guide water from inside the water pipe 5 into the inside of the nozzles 10. Multiple connecting blocks 9 are fixedly connected to the outer wall of the connecting pipe 8. The bottom of the connecting blocks 9 is fixedly connected to the top of the nozzles 10.

[0038] Specifically, during the internal flushing process, external water flow is first guided into the support frame 7 via water pipe 5. The water flow is then conducted to the nozzle 10 via connecting pipe 8 and connecting block 9. Next, motor 6 is started, and its output drives the limiting plate 11 and connecting pipe 8 to rotate on the inner wall of the support frame 7. The design of the support frame 7 ensures that the positions of the limiting plate 11 and connecting pipe 8 are effectively defined. As the connecting pipe 8 rotates, the nozzle 10 also rotates around the connecting pipe 8. During this process, centrifugal force causes the water sprayed from the nozzle 10 to disperse in all directions. This not only expands the spraying range of the nozzle 10 but also ensures that the inner wall of the mixing tank 1 is thoroughly flushed and cleaned. This efficient water flushing significantly improves the cleaning efficiency of the equipment's inner wall, thus preparing it for subsequent material processing.

[0039] Working principle: During equipment use, the material is poured into the mixing tank 1 through the feed pipe 2. Then, the motor 14 is started. The output of the motor 14 drives the connecting column 16 and the sliding column 17 on the outer wall of the connecting plate 15 to rotate. While the sliding column 17 is rotating, it will drive the rotating shaft 20, the stirring blade 24 and the guide hole 25 to rotate. The rotation of the stirring blade 24 stirs the material inside the mixing tank 1. At the same time, the narrow space inside the guide hole 25 is used to stir the material. According to Bernoulli's principle, in the steady flow of an ideal fluid, in the same flow tube, the pressure is low where the flow velocity is high and the pressure is high where the flow velocity is low. When liquid flows through an area with holes, the cross-sectional area of ​​the flow channel becomes smaller at the holes. At this time, the flow velocity at the holes increases and the pressure decreases, while the pressure of the surrounding liquid is relatively high. Under the action of pressure difference, the liquid will be pushed towards the holes, thereby accelerating the flow. While rotating, the shaft 20 will drive the slider 23 to slide on the inner wall of the groove 22. During this process, the connecting column 16 will push the spring 18 to compress through the ball 26 and the connecting plate 19. Using the rebound effect of the spring 18, the slider 23 is guided to slide on the inner wall of the groove 22, so that the stirring blade 24 on the outer wall of the shaft 20 will move up and down while rotating, expanding the stirring range of the equipment and improving the stirring efficiency of the material.

[0040] During the internal rinsing process, water is guided from outside to the support frame 7 via water pipe 5, and then transmitted to the nozzle 10 via connecting pipe 8 and connecting block 9. The nozzle 10 then sprays water into the mixing tank 1. Next, motor 6 is started, and its output drives the limiting plate 11 and connecting pipe 8 to rotate on the inner wall of the support frame 7. The support frame 7 limits the positions of the limiting plate 11 and connecting pipe 8. As the connecting pipe 8 rotates, it drives the nozzle 10 to rotate around the connecting pipe 8. Centrifugal force disperses the water sprayed from the nozzle 10 in all directions, expanding the spraying range of the nozzle 10 and ensuring that the inner wall of the mixing tank 1 is thoroughly rinsed and cleaned, thus improving the cleaning efficiency of the equipment's inner wall.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
