Description

Technical Field

[0001] This utility model relates to the field of gluing equipment technology, specifically a gluing equipment for the production of insulating paper. Background Technology

[0002] A glue applicator, also known as a dispensing machine, coating machine, or dripping machine, is specifically designed to control fluids and apply them drop by drop to the surface of different products to improve their quality and functionality. The application method is determined based on the product requirements.

[0003] According to a public notice (No. CN214637754U) regarding a gluing device for producing diamond-patterned insulating paper, the aforementioned application includes a glue roller. The glue roller is a horizontally arranged cylindrical structure with multiple strip-shaped slits on its side wall. Each strip-shaped slit is a through hole parallel to the axis of the glue roller, and the multiple strip-shaped slits are evenly distributed circumferentially in the middle section of the glue roller.

[0004] However, in actual use, as the glue applicator is used, the outer wall of the diamond-shaped grid gradually becomes covered with glue, making it impossible to maintain the shape of the diamond when the glue is applied to the insulating paper. This results in pattern distortion, and areas with excessive glue are prone to flow, squeezing, and equipment contamination. In view of this, we propose a glue applicator for insulating paper production. Utility Model Content

[0005] The purpose of this invention is to provide a gluing device for the production of insulating paper, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gluing device for insulating paper production, comprising a base plate, a fixing frame fixedly connected to the top end face of the base plate, a material conveying pipe fixedly connected to the side wall of the fixing frame, and a gluing assembly provided on the side wall of the fixing frame, the gluing assembly comprising:

[0007] The inner tube has a transverse groove on its side wall, a sponge layer is fixedly connected to the outer wall of the inner tube, and an outer roller is provided on the outer wall of the inner tube, with a diamond-shaped groove on the outer wall of the outer roller.

[0008] A flow guide block, wherein a guide plate is fixedly connected to the side wall of the flow guide block, and the flow guide block is disposed on the inner wall of the conveying pipe;

[0009] An arc-shaped frame, wherein a groove is opened on the inner bottom surface of the arc-shaped frame, and a scraper is fixedly connected to the inner wall of the groove.

[0010] Preferably, the top end face of the base plate is provided with a guide rail, the guide rail is slidably connected to the movable frame, the side wall of the movable frame is fixedly connected with a motor, the output end of the motor is fixedly connected with a rotating shaft, the end face of the rotating shaft is provided with a slot, and the side wall of the outer roller is fixedly connected with a locking block.

[0011] Preferably, the outer wall of the guide plate is movably connected to the inner wall of the inner tube, the guide block is fixedly connected to the inner wall of the conveying pipe, and the conveying pipe is fixedly connected to the storage tank.

[0012] Preferably, the inner tube is rotatably connected to the conveying tube, the diamond-shaped groove is inserted into the sponge layer, and the inner wall of the outer roller is attached to the outer wall of the sponge layer.

[0013] Preferably, a glue delivery pipe is fixedly connected to the side wall of the arc-shaped frame, and the end of the glue delivery pipe away from the arc-shaped frame is fixedly connected to the side wall of the material delivery pipe. The glue delivery pipe re-enters the glue in the arc-shaped frame into the material delivery pipe.

[0014] Preferably, the arc-shaped frame is in contact with the outer wall of the outer roller, and the arc-shaped frame presses the sponge layer into the diamond-shaped groove. The scraper is in contact with the outer wall of the outer roller, and the scraper scrapes excess glue from the surface of the outer roller into the arc-shaped frame.

[0015] Preferably, the side wall of the fixing frame is rotatably connected to a rotating roller, and the top end face of the base plate is hinged to a hinge rod.

[0016] Compared with the prior art, this utility model provides a gluing device for insulating paper production, which has the following beneficial effects:

[0017] 1. This gluing device for insulating paper production uses a set gluing components. The arc frame presses the sponge layer into the diamond-shaped groove, and then the scraper scrapes the excess glue on the surface of the outer roller into the arc frame, treating the excess glue residue on the surface of the outer roller. This prevents diffusion or glue flying, ensuring a clear gluing pattern, neat edges, and uniform thickness. The glue guide plate presses the glue into the sponge layer. During the compression process, the glue is more likely to enter the porous sponge layer, preventing the glue from floating on the surface of the sponge layer and not being fully absorbed. This ensures sufficient glue storage in the sponge, avoids dry areas, and prevents defects such as glue breaks or empty spots during gluing.

[0018] 2. This gluing device for insulating paper production uses a guide rail to pull out the outer roller. By replacing the outer roller and the corresponding sponge layer, the gluing pattern can be changed quickly. Different patterns can be switched quickly without complicated tools, reducing production line downtime caused by equipment maintenance. At the same time, it can meet the needs of multi-variety, small-batch customized production, improve the flexible manufacturing capability of the production line, and adapt to different customer needs.

[0027] like Figures 1-7 As shown, this utility model provides a technical solution: a gluing device for insulating paper production, including a base plate 1, a fixing frame 2 fixedly connected to the top end face of the base plate 1, a material conveying pipe 3 fixedly connected to the side wall of the fixing frame 2, and a gluing assembly 4 provided on the side wall of the fixing frame 2. The gluing assembly 4 includes an inner tube 401, a transverse groove 402, a glue guide plate 403, a flow guide block 404, an outer roller 405, a diamond-shaped groove 406, a sponge layer 407, an arc-shaped frame 408, a groove opening 409, and a scraper 410.

[0028] In one embodiment of this utility model, the inner tube 401 is rotatably connected to the conveying pipe 3. A transverse groove 402 is provided on the side wall of the inner tube 401. A sponge layer 407 is fixedly connected to the outer wall of the inner tube 401. An outer roller 405 is provided on the outer wall of the inner tube 401. A diamond-shaped groove 406 is provided on the outer wall of the outer roller 405. The diamond-shaped groove 406 is inserted into the sponge layer 407. The inner wall of the outer roller 405 is in contact with the outer wall of the sponge layer 407.

[0029] The guide block 404 is fixedly connected to the inner wall of the conveying pipe 3. The side wall of the guide block 404 is fixedly connected to the guide plate 403. The guide block 404 is set on the inner wall of the conveying pipe 3. The outer wall of the guide plate 403 is movably connected to the inner wall of the inner pipe 401. The conveying pipe 3 is fixedly connected to the storage tank 13.

[0030] The inner bottom surface of the arc frame 408 has a groove 409. A scraper 410 is fixedly connected to the inner wall of the groove 409. A glue supply pipe 5 is fixedly connected to the side wall of the arc frame 408. The end of the glue supply pipe 5 away from the arc frame 408 is fixedly connected to the side wall of the material supply pipe 3. The glue supply pipe 5 re-inputs the glue in the arc frame 408 into the material supply pipe 3. The arc frame 408 is in contact with the outer wall of the outer roller 405. The arc frame 408 presses the sponge layer 407 into the diamond groove 406. The scraper 410 is in contact with the outer wall of the outer roller 405. The scraper 410 scrapes the excess glue on the surface of the outer roller 405 into the arc frame 408.

[0031] A rotating roller 12 is rotatably connected to the side wall of the fixed frame 2, a hinge rod 11 is hinged to the top end face of the base plate 1, a guide rail 10 is provided on the top end face of the base plate 1, the guide rail 10 is slidably connected to the movable frame 6, and a motor 7 is fixedly connected to the side wall of the movable frame 6.

[0032] The storage tank 13 feeds the glue into the inner tube 401 through the delivery pipe 3. The motor 7 drives the outer roller 405, the sponge layer 407, and the inner tube 401 to rotate. The insulating paper passes between the rotating roller 12 and the outer roller 405, thereby transferring the glue absorbed by the sponge layer 407 onto the surface of the insulating paper. The inner tube 401 rotates, forming relative motion with the glue guide plate 403. The rotation of the inner tube 401 drives the glue to rotate, causing the glue to enter the gap between the glue guide plate 403 and the inner tube 401. The gap between the glue guide plate 403 and the inner tube 401 gradually decreases, which is equivalent to applying a certain pressure to the glue, thereby pressing the glue into the sponge layer 407. During the compression process, the glue can more easily penetrate the porous sponge layer 407, preventing the glue from floating on the surface of the sponge layer 407 and not being fully absorbed. This ensures that the sponge has sufficient glue storage, prevents dry areas, and avoids defects such as glue breakage or empty spots during application. The outer roller 405 rotates, causing it to pass under the arc frame 408. The arc frame 408 presses the sponge layer 407 into the diamond groove 406. Then, the scraper 410 scrapes the excess glue on the surface of the outer roller 405 into the arc frame 408, treating the excess glue residue on the surface of the outer roller 405. This prevents diffusion or glue flying, ensuring that the glued pattern is clear, the edges are neat, and the thickness is uniform.

[0033] In addition, a rotating shaft is fixedly connected to the output end of the motor 7, and a slot 8 is opened on the end face of the rotating shaft. A locking block 9 is fixedly connected to the side wall of the outer roller 405. By rotating the hinge rod 11, the movable frame 6 can be slid, and the outer roller 405 can be pulled out. By replacing the outer roller 405 and the corresponding sponge layer 407, the locking block 9 of the outer roller 405 is inserted into the slot 8 to realize the replacement of the adhesive pattern. Different patterns can be quickly switched without complicated tools, reducing production line downtime caused by equipment maintenance. At the same time, it can meet the needs of multi-variety, small-batch customized production, improve the flexible manufacturing capability of the production line, and adapt to different customer needs.

[0034] In this invention, during use, the storage tank 13 feeds the glue into the inner tube 401 through the delivery pipe 3. The motor 7 drives the outer roller 405, the sponge layer 407, and the inner tube 401 to rotate. The insulating paper passes between the rotating roller 12 and the outer roller 405, thereby transferring the glue absorbed by the sponge layer 407 onto the surface of the insulating paper. The inner tube 401 rotates, forming a relative motion with the glue guide plate 403. The rotation of the inner tube 401 drives the glue to rotate, allowing the glue to enter between the glue guide plate 403 and the inner tube 401. The gap between the guide plate 403 and the inner tube 401 gradually decreases, which is equivalent to applying a certain pressure to the glue, thereby pressing the glue into the sponge layer 407. The outer roller 405 rotates, so that the outer roller 405 passes the bottom of the arc frame 408. The arc frame 408 presses the sponge layer 407 into the diamond groove 406. Then the scraper 410 scrapes the excess glue on the surface of the outer roller 405 into the arc frame 408, thus treating the excess glue remaining on the surface of the outer roller 405 and preventing diffusion or glue flying.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
