Description

Technical Field

[0001] This utility model relates to the field of adhesive processing technology, and in particular to an adhesive impurity removal device. Background Technology

[0002] White glue is one of the most widely used, largest-volume, and oldest water-soluble adhesives. It is a thermoplastic adhesive produced by the polymerization reaction of vinyl acetate monomer under the action of an initiator. During the production of this liquid adhesive, some raw materials may contain impurities, resulting in some impurities in the initial stage of the adhesive production. Therefore, to improve the purity and quality of the adhesive, specialized impurity removal equipment is used to remove these impurities.

[0003] In the prior art, a utility model patent document with authorization announcement number CN212369644U and titled "Impurity Removal Device for Adhesive Production" discloses an impurity removal device for adhesive production. This device includes a main body with an inner cavity containing a corrugated pipe. The upper end of the corrugated pipe is connected to the top wall of the inner cavity, and the lower end is connected to the bottom wall of the inner cavity. A filter chamber is formed inside the corrugated pipe, and a mechanical cavity is formed between the corrugated pipe and the main body. A feed hopper is located above the main body, and an electric telescopic rod is fixedly mounted on it. A connecting rod is connected to the lower end of the electric telescopic rod, and a cover plate and a blocking plate are mounted on it. A rotating motor is located on the main body and connected to a threaded rod. The threaded rod extends downward into the mechanical cavity, and its lower end is rotatably connected to the bottom of the mechanical cavity. The lower end of the feed hopper extends into the filter chamber and is connected to an extrusion plate. A filter plate is located below the extrusion plate, and a fixed frame is located around the filter plate, which is connected to the inner wall of the corrugated pipe. A threaded sleeve is spirally connected to the threaded rod and fixed to the outer wall of the corrugated pipe at the fixed frame. A discharge pipe is located at the lower end of the main body, which communicates with the filter chamber.

[0004] In the aforementioned patent literature, during operation, the filter plate is moved upward to contact the extrusion plate, thereby squeezing the adhesive and filtering it. However, by simply using the extrusion filtration method, some adhesive will still remain on the filter plate. This part of the adhesive can only be cleaned along with the filter plate, which is wasteful and costly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adhesive impurity removal device. This device solves the problem mentioned in the background art where, during operation, some adhesive impurity removal devices move the filter plate upwards to contact the extrusion plate, thereby squeezing the adhesive and filtering it. However, by simply using the squeezing method, some adhesive remains on the filter plate, which can only be cleaned along with the filter plate, resulting in waste and high costs.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An adhesive impurity removal device includes a base plate with supporting legs. A box with a top opening is fixed on the supporting legs. A first inlet is opened on the side wall of the box. A horizontally movable support block is provided above the box. A first air rod and two second air rods are fixed at the bottom of the support block. The two second air rods are respectively located on both sides of the first air rod. The telescopic end of the first air rod faces the box and is fixedly connected to a first pressure plate. Two second pressure plates are rotatably connected to both sides of the first pressure plate. The telescopic ends of the two second air rods face the box and are rotatably connected to sliding blocks. Each of the two second pressure plates has a sliding groove. The two sliding blocks are slidably disposed in the two sliding grooves. A filter plate is provided inside the box and is located below the first pressure plate and the two second pressure plates. The two second pressure plates are used to contact the filter plate after rotating relative to the first pressure plate. A discharge port is opened at the bottom of the box.

[0008] Working principle:

[0009] When in use, the material is fed into the box through the first inlet.

[0010] Then, the first air spring and the two second air springs are activated, causing the telescopic ends of the first air spring and the two second air springs to extend. This simultaneously drives the corresponding first pressure plate and the two second pressure plates to move downwards. The first pressure plate and the two second pressure plates gradually approach the filter plate and come into contact with it, squeezing the adhesive and filtering it.

[0011] Then, the first air spring and the two second air springs are activated, causing the telescopic ends of the first air spring and the two second air springs to retract, which in turn drives the corresponding first pressure plate and the two second pressure plates to move upward.

[0012] Then, the two second air rods are activated, and the telescopic ends of the two second air rods extend, pushing the two second pressure plates to rotate relative to the first pressure plate at a certain angle, so that the ends of the second pressure plates contact the filter plate. During this process, the rotation of the sliding block and the sliding in the groove cooperate with the rotation of the second pressure plate.

[0013] Then the support block is moved horizontally. Because the adhesive material used to remove impurities in this device is fluid, the movement of the support block causes the second pressure plate to push the adhesive remaining on the filter plate. The remaining adhesive is squeezed by external force and thus scraped into the filter plate for further filtration.

[0014] Finally, the adhesive, after being filtered by the filter plate, flows out through the outlet and is collected by workers, who then treat any impurities remaining on the filter plate.

[0015] Beneficial effects:

[0016] 1. By setting a first feed port, a first air rod, two second air rods, a first pressure plate, two second pressure plates, and a filter plate, the telescopic ends of the first air rod and the two second air rods extend, synchronously driving the corresponding first pressure plate and two second pressure plates to move downward. The first pressure plate and the two second pressure plates gradually approach and contact the filter plate, squeezing the adhesive. Thus, by squeezing, the filtration efficiency of the adhesive is greatly accelerated, and the adhesive is initially filtered.

[0017] 2. By setting up sliding blocks and chutes, after the initial extrusion is completed, the first pressure plate and two second pressure plates are raised synchronously, and then the two second air rods are started again. Only the rotation and sliding cooperation of the sliding blocks can make the two second pressure plates rotate.

[0018] 3. By setting up a horizontally movable support block, the movement of the support block drives the second pressure plate, which has rotated by a certain angle, to move horizontally. This applies pressure to the adhesive residue on the surface of the filter plate, causing the residue to flow through the filter plate under the push of the second pressure plate, thereby performing secondary filtration of the adhesive, further improving the filtration effect of the adhesive and reducing adhesive waste.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example:

[0024] like Figure 1 and Figure 2As shown, an adhesive impurity removal device includes a base plate 1, a support leg 2 on the base plate 1, and a box 3 with a top opening fixed on the support leg 2. The box 3 is a hollow cube, and a first inlet 4 is opened on the side wall of the box 3. A horizontally movable support block 5 is provided above the box 3. A first air rod 6 and two second air rods 7 are fixed at the bottom of the support block 5. The two second air rods 7 are respectively located on both sides of the first air rod 6. The telescopic end of the first air rod 6 faces the box 3 and is fixedly connected to a first pressure plate 8. Two second pressure plates 9 are rotatably connected to both sides of the first pressure plate 8. The telescopic ends of the two second air rods 7 face the box 3 and are rotatably connected to sliding blocks 10. Both second pressure plates 9 have openings inside. There is a sliding groove 11, and two sliding blocks 10 are slidably disposed in the two sliding grooves 11. The telescopic end of the second air rod 7 is rotatably connected to a rotating shaft. The sliding block 10 has a U-shaped structure. The two ends of the sliding block 10 are fixedly disposed at the two ends of the rotating shaft extending outward from the telescopic end of the second air rod 7. The box body 3 is provided with a filter plate 12. The filter plate 12 is disposed below the first pressure plate 8 and two second pressure plates 9. The two second pressure plates 9 are used to contact the filter plate 12 after rotating relative to the first pressure plate 8. The bottom of the box body 3 has a discharge port 13. The filter plate 12 is snapped into the box body 3. Since the four sides of the bottom of the box body 3 are inclined towards the discharge port 13, the filter plate 12 can be firmly snapped into the box body 3.

[0025] By setting up a first feed inlet 4, a first air rod 6, two second air rods 7, a first pressure plate 8, two second pressure plates 9, and a filter plate 12, the telescopic ends of the first air rod 6 and the two second air rods 7 extend, synchronously driving the corresponding first pressure plate 8 and two second pressure plates 9 to move downwards. The first pressure plate 8 and the two second pressure plates 9 gradually approach and contact the filter plate 12, squeezing the adhesive. Thus, the filtration efficiency of the adhesive is greatly accelerated through squeezing, and the adhesive is initially filtered. By setting up a sliding block 10 and a sliding groove 11, after the initial squeezing is completed, the first pressure plate 8 and the two second pressure plates 9 are raised synchronously. Then, the two second air rods 7 are activated again, causing the telescopic ends of the second air rods 7 to extend. The rotation and sliding cooperation of the sliding block 10 enable the second pressure plate 9 to rotate.

[0026] By setting a horizontally movable support block 5, the movement of the support block 5 causes the second pressure plate 9, which has rotated by a certain angle, to move horizontally, thereby applying pressure to the adhesive residue on the surface of the filter plate 12. This causes the residual adhesive to flow through the filter plate 12 under the push of the second pressure plate 9, thereby performing secondary filtration of the adhesive, further improving the filtration effect of the adhesive and reducing adhesive waste.

[0027] like Figure 1As shown, the filter plate 12 has several filter holes 14 penetrating through it. These filter holes 14 are used to isolate impurities and prevent them from passing through the filter holes along with the flowing adhesive. The bottom of the first pressure plate 8 and the two second pressure plates 9 are each fixed with a piercing needle 15, which is used to penetrate into the filter holes 14. As the first pressure plate 8 and the two second pressure plates 9 move downwards, the piercing needle 15 gradually approaches the filter plate 12 and extends into the filter holes 14, thereby clearing any blockages in the filter holes 14 and preventing the adhesive from being unable to flow. Both sides of the housing 3 have through holes 22 for the passage of two second pressure plates 9 and puncture needles 15. In use, after the first pressure plate 8 and the two second pressure plates 9 are raised to a certain position, one of the second air rods 7 is activated first. The telescopic end of the second air rod 7 extends and pushes the second pressure plate 9 connected to the second air rod 7 to rotate. After the second pressure plate 9 rotates to a certain angle, it contacts the filter plate 12. Then, the support block 5 is moved horizontally, which drives the second pressure plate 9 to move and apply pressure to the adhesive remaining on the surface of the filter plate 12. At the same time, the other second pressure plate 9 also moves horizontally at the same time and passes through the through hole 22 to prevent the other second pressure plate 9 from colliding with the housing 3, which would prevent the support block 5 from moving. Since this device improves the filtration effect by filtering the adhesive in small amounts multiple times, the amount of adhesive added will not exceed the through hole 22. Therefore, the adhesive will not flow out from the through hole 22 and cause waste of adhesive.

[0028] like Figure 1 and Figure 2 As shown, a protective cover 16 is fixed on the base plate 1, and the box 3 is located inside the protective cover 16. A second inlet 17 is opened on the side wall of the protective cover 16, corresponding to the first inlet 4, for externally connecting a material pipe. Therefore, after the material pipe is placed inside the first inlet 4 and the second inlet 17, the material is fed into the box 3 through the material pipe. A door panel 18 is snapped onto the protective cover 16. The snap-fit ​​method of the door panel 18 is existing technology and will not be described in detail here. Opening the door panel 18 facilitates workers' entry and exit from the protective cover 16. The protective cover 16 prevents toxic gases from drifting outwards. A ventilation device is also installed inside the protective cover 16 to absorb toxic gases generated during the adhesive filtration process, preventing environmental pollution. This device is existing technology and will not be described in detail here. Figure 2 As shown, an electric slide rail 19 is fixedly mounted on the top of the protective cover 16, and an electric slider 20 is slidably mounted inside the electric slide rail 19. The support block 5 is fixedly connected to the electric slider 20. The arrangement of the electric slide rail 19 and the electric slider 20 specifically realizes the horizontal movement of the support block 5. This method is mechanized and automated, and easy to operate.

[0029] like Figure 2As shown, the end of each second pressure plate 9 furthest from the first pressure plate 8 is an inclined surface, which is inclined towards the puncture needle 15. This inclined surface increases the contact area between the second pressure plate 9 and residual adhesive during horizontal movement, further improving the filtration effect. Figure 1 and Figure 2 As shown, a collection box 21 is provided on the base plate 1. The collection box 21 has an opening at the top and is located below the box body 3, with the opening of the collection box 21 facing the discharge port 13. The collection box 21 can collect the adhesive flowing out from the discharge port 13, making it convenient for workers to remove.

[0030] Working principle:

[0031] Before use, the material is fed into the box 3 by connecting the material pipes inside and outside the first inlet 4 and the second inlet 17.

[0032] When in use, start the first air rod 6 and the two second air rods 7. The telescopic ends of the first air rod 6 and the two second air rods 7 extend, which simultaneously drives the corresponding first pressure plate 8 and two second pressure plates 9 to move downward. The first pressure plate 8 and the two second pressure plates 9 gradually approach the filter plate 12 and come into contact with the filter plate 12, squeezing the adhesive and performing preliminary filtration of the adhesive.

[0033] The squeezing action can be repeated multiple times. At the same time, the puncture needle 15 continuously penetrates the filter hole 14 and clears the inside of the filter hole 14.

[0034] Then, the first air spring 6 and the two second air springs 7 are activated. The telescopic ends of the first air spring 6 and the two telescopic ends of the two second air springs 7 retract, which simultaneously drives the corresponding first pressure plate 8 and the two second pressure plates 9 to move upward to a certain position.

[0035] Then, one of the second air rods 7 is activated. The telescopic end of the second air rod 7 extends and pushes the corresponding second pressure plate 9 to rotate relative to the first pressure plate 8 at a certain angle, so that the end of the second pressure plate 9 contacts the filter plate 12. During this process, the rotation of the sliding block 10 and the sliding in the slide groove 11 cooperate with the rotation of the second pressure plate 9.

[0036] Then, the electric slider 20 is activated to drive the support block 5 to move horizontally. The movement of the support block 5 causes the rotating second pressure plate 9 to push the adhesive remaining on the filter plate 12. The remaining adhesive is squeezed by external force and flows through the filter hole 14 for further filtration. At this time, another second pressure plate 9 moves horizontally and passes through the through hole 22.

[0037] Then, one of the second air rods 7 is activated, causing the telescopic end of the second air rod 7 to retract, which drives the corresponding second pressure plate 9 to rotate back to be parallel with the first pressure plate 8. Then, the other second air rod 7 is activated, pushing the other second pressure plate 9 to rotate. The above steps are repeated, and the other second pressure plate 9 pushes the adhesive remaining on the other half of the filter plate through the filter hole 14 for further filtration.

[0038] Finally, the compressed adhesive passes through the filter hole 14, flows out from the outlet 13, and flows into the collection box 21.

[0039] Workers open the door panel 18 to collect and process the materials in the collection box 21, and remove the impurities remaining on the filter plate 12, thus completing the entire operation.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
