Description

Technical Field

[0001] This utility model relates to the field of impregnation equipment, specifically to an impregnation device for producing adhesive-coated paper. Background Technology

[0002] Adhesive-coated paper, also known as diamond-patterned adhesive insulating paper, is an interlayer insulating material made by coating a special modified epoxy resin in a diamond pattern onto a high-performance insulating paper (such as power cable paper or polyester film composite paper) as the base material.

[0003] The impregnation process is a core step in the production of adhesive-coated paper. Its purpose is to uniformly coat the substrate (such as paper, film, or fabric) with adhesive to form a composite material with specific properties. This process directly affects key indicators such as the adhesive strength, weather resistance, and flexibility of the adhesive-coated paper. However, as the impregnation process progresses, the amount of adhesive in the impregnation tank gradually decreases. When the adhesive level is lower than the impregnation roller, it becomes impossible to coat the adhesive-coated paper with adhesive. This requires operators to constantly monitor the adhesive level in the impregnation tank, increasing their workload. Furthermore, directly adding adhesive to the impregnation tank can introduce air into the adhesive, forming tiny bubbles and causing surface quality defects in the impregnated adhesive-coated paper. Utility Model Content

[0004] To address the technical problems of existing methods that require operators to constantly monitor the level of adhesive in the dipping tank, increasing their workload, and that adding adhesive directly to the dipping tank can introduce air into the adhesive, forming microbubbles and causing surface quality defects in the glued paper after dipping, this utility model provides a dipping device for glued paper production.

[0005] The technical solution adopted by this utility model is as follows: it includes a base, on which a glue-dipping tank is fixedly installed. Two sets of glue-dipping rollers are rotatably installed in the glue-dipping tank. Adhesive paper is provided on the outside of the two sets of glue-dipping rollers. A glue inlet is opened on the side wall of the glue-dipping tank. A baffle is slidably arranged on the inner side wall of the glue-dipping tank. A connecting rod is fixedly installed on the baffle. A float is fixedly installed on the connecting rod. A glue storage tank is arranged on one side of the glue-dipping tank. The glue storage tank is used to replenish glue in the glue-dipping tank. A connecting pipe is fixedly installed between the glue storage tank and the glue-dipping tank.

[0006] Furthermore, a stabilizing block is fixedly installed on the top of the connecting rod, and a sliding groove is provided on the inner side wall of the impregnation tank. A slider is slidably connected in the sliding groove, and the slider is fixedly installed on one side of the stabilizing block.

[0007] By adopting the above technical solution, the stability of the baffle during movement is improved.

[0008] Furthermore, a support base is provided on one side of the impregnation tank, the glue storage tank is fixedly installed on the support base, a feed pipe is fixedly connected to the glue storage tank, and an observation window is fixedly installed on the surface of the glue storage tank.

[0009] By adopting the above technical solution, it is convenient to replenish the adhesive in the storage tank in a timely manner.

[0010] Furthermore, two sets of mounting plates are fixedly installed on the impregnation tank. One set of mounting plates has two sets of feed rollers rotatably mounted on it, and the other set of mounting plates has two sets of discharge rollers rotatably connected to it.

[0011] By adopting the above technical solutions, the stability of the adhesive paper during the impregnation process can be improved.

[0012] Furthermore, a constant temperature heating block is fixedly installed inside the impregnation tank, a stirring rod is rotatably installed at the bottom of the impregnation tank, an anchor-type stirring blade is fixedly connected to the stirring rod, and an auger blade is fixedly installed on the outside of the stirring rod.

[0013] By adopting the above technical solution, the uniformity of the adhesive solution is improved.

[0014] Furthermore, a low-speed motor is fixedly installed on one side of the base, and a rotating shaft is coaxially fixedly connected to the drive shaft of the low-speed motor. A first bevel gear is fixedly connected to one end of the rotating shaft, and a second bevel gear meshes with one side of the first bevel gear. The second bevel gear is fixedly installed at the bottom of the stirring rod.

[0015] By adopting the above technical solution, the anchor-type stirring blade is driven to rotate.

[0016] Furthermore, a support rod is fixedly connected to the inner wall of the glue-impregnation tank, and a lower scraper is fixedly installed at one end of the support rod. The lower scraper is positioned below the glue-dispensing paper. An upper scraper is fixedly installed inside the glue-impregnation tank and positioned above the glue-dispensing paper. A glue discharge groove is formed on the upper scraper.

[0017] By adopting the above technical solution, excess adhesive on the adhesive paper can be scraped off.

[0018] The beneficial effects of this utility model are: by using the glue-dipping tank in conjunction with the glue storage tank, feed pipe, connecting pipe, glue inlet, baffle, connecting rod, float plate and stabilizing block, the glue liquid in the glue storage tank is automatically replenished to the glue-dipping tank, eliminating the need for operators to constantly monitor the glue liquid level in the glue-dipping tank, reducing the frequency of adding glue liquid to the device, reducing the labor intensity of operators, and ensuring the glue-dipping quality of the glue-dispensing paper. The adhesive solution in the impregnation tank is slowly stirred by a low-speed motor in conjunction with a rotating shaft, a first bevel gear, a second bevel gear, a stirring rod, an anchor-type stirring blade, and an auger blade, which improves the uniformity and fluidity of the adhesive solution, while eliminating tiny air bubbles in the adhesive solution and improving the impregnation quality of the dispensing paper. The device uses a support rod in conjunction with a lower scraper, an upper scraper, and a glue discharge tank to scrape off excess glue from the upper and lower surfaces of the glued paper after impregnation, ensuring a uniform glue thickness on the paper. The scraped-off glue falls back into the impregnation tank under gravity, reducing glue waste and improving the device's practicality. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 The present invention will be further described below.

[0024] To address the problems existing in the background art, this application proposes the following technical solution: A base 1 is included, on which a glue-impregnating tank 2 is fixedly installed. Two sets of glue-impregnating rollers 3 are rotatably installed in the glue-impregnating tank 2. Adhesive paper 4 is applied to the outside of the two sets of glue-impregnating rollers 3. A glue inlet 12 is opened on the side wall of the glue-impregnating tank 2. A baffle 13 is slidably installed on the inner side wall of the glue-impregnating tank 2. A connecting rod 14 is fixedly installed on the baffle 13. A float 15 is fixedly installed on the connecting rod 14. A glue storage tank 9 is provided on one side of the glue-impregnating tank 2. The glue storage tank 9 is used to replenish the glue in the glue-impregnating tank 2. A connecting pipe 11 is fixedly installed between the glue storage tank 9 and the glue-impregnating tank 2.

[0025] The adhesive-dispensing paper 4 passes over two sets of dipping rollers 3. The adhesive in the dipping tank 2 submerges the adhesive-dispensing paper 4 between the two sets of dipping rollers 3, so that the adhesive-dispensing paper 4 is 5cm below the adhesive surface. The time for the adhesive-dispensing paper 4 to pass through the two sets of dipping rollers 3 is 10-20 seconds. The adhesive is evenly coated on both the upper and lower surfaces of the adhesive-dispensing paper 4 between the two sets of dipping rollers 3. The float 15 floats on the adhesive. As the dipping operation proceeds, the adhesive level in the dipping tank 2 drops, and the float 15 drops with the adhesive level. The float 15 drives the baffle 13 to move downward through the connecting rod 14, so that the baffle 13 is removed from the position of the glue inlet 12. After the glue inlet 12 is no longer blocked by the baffle 13, the dipping tank 2 is connected to the inside of the glue storage tank 9 through the connecting pipe 11. The adhesive in the glue storage tank 9 passes through the connecting pipe 11. The glue inlet 12 enters the glue tank 2 to replenish the glue. After the glue is replenished, the glue level in the glue tank 2 rises, and the float 15 moves upward to block the glue inlet 12 again with the baffle 13. The glue in the storage tank 9 no longer enters the glue tank 2, thus realizing automatic replenishment of the glue in the glue tank 2. The operator does not need to pay attention to the glue level in the glue tank 2, which reduces the labor intensity of the operator and ensures the glue quality of the dispensing paper 4. At the same time, the glue inlet 12 is set below the glue level, so that the outside air will not be brought into it when replenishing the glue, reducing the generation of tiny air bubbles in the glue and reducing the occurrence of pitting on the surface of the dispensing paper caused by air bubbles, thereby improving the glue quality of the dispensing paper 4.

[0026] Furthermore, a stabilizing block 16 is fixedly installed on the top of the connecting rod 14, and a sliding groove 17 is provided on the inner side wall of the impregnation tank 2. A slider 18 is slidably connected in the sliding groove 17, and the slider 18 is fixedly installed on one side of the stabilizing block 16.

[0027] The slider 18, together with the slide groove 17, guides and limits the movement of the stabilizing block 16. The stabilizing block 16, together with the connecting rod 14, improves the stability of the baffle 13 when it moves, ensuring the sealing effect of the baffle 13 on the glue inlet 12.

[0028] To further explain, a support base 8 is provided on one side of the glue-dipping tank 2, and the glue storage tank 9 is fixedly installed on the support base 8. A feed pipe 10 is fixedly connected to the glue storage tank 9, and an observation window 31 is fixedly installed on the surface of the glue storage tank 9.

[0029] The support base 8 provides installation conditions for the glue storage tank 9. The remaining glue level in the glue storage tank 9 can be viewed through the observation window 31, allowing the operator to replenish the glue in the storage tank 9 in a timely manner through the feed pipe 10. The observation window 31 is made of transparent glass or acrylic material. With the automatic replenishment of the glue tank 2 by the glue storage tank 9, it is only necessary to add glue to the storage tank 9 in a timely manner to ensure that the glue level in the glue tank 2 is maintained at a stable level. There is no need to frequently add glue to the glue tank 2 to adjust the liquid level, thus reducing the labor intensity of the operator.

[0030] To further explain, two sets of mounting plates 5 are fixedly installed on the impregnation tank 2. Two sets of feed rollers 6 are rotatably installed on one set of mounting plates 5, and two sets of discharge rollers 7 are rotatably connected to the other set of mounting plates 5.

[0031] The adhesive paper 4 passes sequentially between two sets of feed rollers 6, around the outside of two sets of dip rollers 3, and between two sets of discharge rollers 7 (as shown in the attached diagram). Figure 2 As shown), the adhesive paper 4 can be stably dipped in the dip tank 2 to ensure the quality of the adhesive dipping of the adhesive paper 4. The adhesive paper 4 is moved by an external traction device.

[0032] Furthermore, a constant temperature heating block 30 is fixedly installed inside the impregnation tank 2, a stirring rod 19 is rotatably installed at the bottom of the impregnation tank 2, an anchor-type stirring blade 20 is fixedly connected to the stirring rod 19, and an auger blade 21 is fixedly installed on the outside of the stirring rod 19.

[0033] The constant temperature heating block 30 keeps the adhesive in the impregnation tank 2 at a stable temperature, controlled between 25-30℃, to prevent premature curing of the adhesive. The stirring rod 19 drives the anchor stirring blade 20 to rotate, which stirs the adhesive in the impregnation tank 2, improving the uniformity and fluidity of the adhesive. The rotation of the anchor stirring blade 20 causes the adhesive to flow in a laminar rather than turbulent manner, and the low shear force generated on the adhesive helps to protect the performance of the adhesive. At the same time, the stirring rod 19 drives the auger blade 21 to rotate, which transports the adhesive at the bottom to the upper part of the feed pipe 10 for stirring, further improving the uniformity and fluidity of the adhesive and improving the coating effect of the adhesive on the dispensing paper 4.

[0034] To further explain, a low-speed motor 22 is fixedly installed on one side of the base 1. A rotating shaft 23 is coaxially fixedly connected to the drive shaft of the low-speed motor 22. A first bevel gear 24 is fixedly connected to one end of the rotating shaft 23. A second bevel gear 25 is meshed on one side of the first bevel gear 24. The second bevel gear 25 is fixedly installed at the bottom of the stirring rod 19.

[0035] The low-speed motor 22 drives the rotating shaft 23 to rotate, which in turn drives the first bevel gear 24 to rotate. The first bevel gear 24 then drives the second bevel gear 25 to rotate. The second bevel gear 25, through the stirring rod 19, drives the anchor stirring blade 20 and the auger blade 21 to rotate, slowly stirring the adhesive solution. This improves the uniformity and fluidity of the adhesive solution and also eliminates air bubbles in the solution, reducing pinhole defects on the surface of the glued paper 4 after impregnation. By cooperating with the first bevel gear 24 and the second bevel gear 25, the rotation shaft 23 ensures that the low-speed motor 22 drives the stirring rod 19 while reducing the overall height of the base 1 and the impregnation tank 2.

[0036] Furthermore, a support rod 26 is fixedly connected to the inner wall of the glue-impregnation tank 2. A lower scraper 27 is fixedly installed at one end of the support rod 26. The lower scraper 27 is located below the glue-dispensing paper 4. An upper scraper 28 is fixedly installed inside the glue-impregnation tank 2. The upper scraper 28 is located above the glue-dispensing paper 4. A glue discharge groove 29 is opened on the upper scraper 28.

[0037] As the glued paper 4 moves after being impregnated, the glue at the bottom of the paper 4 comes into contact with the lower scraper 27. The lower scraper 27 scrapes off the excess glue below the paper 4, and the scraped glue falls back into the impregnation tank 2 under the action of gravity. The glue on the upper surface of the paper 4 is released from the upper scraper 28, which scrapes off the excess glue on the upper surface of the paper 4. The glue discharge tank 29 is set in a "V" shape (as shown in the attached figure). Figure 6 As shown in the figure, the scraped adhesive flows along the "V"-shaped inclined surface and drips back into the adhesive tank 2 from the edge of the upper scraper 28, reducing adhesive waste and improving the practicality of the device.

[0038] The dipping roller 3, anchor-type stirring blade 20, auger blade 21, low-speed motor 22, and constant temperature heating block 30 of the dipping device for dispensing paper production of this utility model are all purchased from the market and are existing technologies. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art. The various electrical components in the device are linked and cooperated through a programmable PLC controller. The electrical connections between the electrical components and the programming of the controller all adopt existing technologies. This utility model does not improve the circuit connection and programming. The dipping roller 2, feeding roller 6, and dispensing roller 7 are all driven by external drive devices.

[0039] The specific operation is as follows: The adhesive paper 4 is passed sequentially through the feed roller 6, the dipping roller 3, and the discharge roller 7. An external traction device pulls the adhesive paper 4 within the dipping tank 2. The adhesive in the tank 2 submerges the adhesive paper 4 between the two sets of dipping rollers 3, evenly coating both the upper and lower surfaces. As the dipping process continues, the adhesive level in the tank 2 decreases. The float 15 descends with the adhesive level, and the float 15, via the connecting rod 14, moves the baffle 13 downwards, causing it to move away from the inlet 12. The inlet 12 then loses the baffle 13. After the sealing of 3, the glue-impregnating tank 2 is connected to the inside of the glue storage tank 9 through the connecting pipe 11. The glue liquid in the glue storage tank 9 enters the glue-impregnating tank 2 through the connecting pipe 11 and the glue inlet 12 to replenish the glue liquid. After the glue liquid is replenished, the glue liquid level in the glue-impregnating tank 2 rises, and the float 15 moves upward to make the baffle 13 seal the glue inlet 12 again. The glue liquid in the glue storage tank 9 no longer enters the glue-impregnating tank 2, realizing the automatic replenishment of the glue liquid in the glue-impregnating tank 2. The operator does not need to pay attention to the glue liquid level in the glue-impregnating tank 2, which reduces the labor intensity of the operator and ensures the glue impregnation quality of the glue-applied paper 4.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
