Abstract
Description
Technical Field
[0001] This utility model relates to the field of paperboard processing technology, specifically a paperboard production processing equipment. Background Technology
[0002] Paperboard is a flat material made of single or multiple layers of paper, mainly used for making packaging boxes and other packaging containers. In the paperboard processing, gluing is a key process for achieving paperboard bonding (such as bonding the face paper and core paper of corrugated paperboard, and laminating multiple layers of hardboard). The quality of gluing directly affects the bonding strength and stability of the finished paperboard.
[0003] Currently, in the paperboard production process, the gluing process requires adjusting the gluing range according to the width of the paperboard. If the gluing width does not match the paperboard width, it will lead to glue waste (glue exceeding the paperboard width) or adhesion failure (glue not covering the edges of the paperboard). Existing gluing equipment has significant drawbacks: most gluing components are designed with a fixed width. When changing to paperboard of different widths, it is necessary to disassemble and replace components such as the gluing roller and glue distribution pipe, which is cumbersome, time-consuming, and seriously affects production efficiency. Therefore, it is urgent to design a processing equipment for paperboard production to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a processing equipment for paperboard production to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A cardboard production processing device includes a housing. A coating roller is rotatably connected to the inner wall of the housing near the center, and an applicator roller is rotatably connected to the inner wall of the housing near the coating roller. A glue feeding pipe is fixedly installed on the housing and is located above the gap between the coating roller and the applicator roller. Baffles are fitted on both sides of the outer walls of the glue feeding pipe and the coating roller. A spacing adaptation mechanism for adjusting the distance between the two baffles is provided on the housing. Equally spaced conveyor rollers are rotatably arranged on the housing, and a drive mechanism is provided at one end of the conveyor roller, the applicator roller, and the coating roller.
[0007] Furthermore, the spacing adaptation mechanism includes a bidirectional screw rotatably mounted on the inner wall of the top of the housing, and both ends of the bidirectional screw are screwed with movable frames. The bottom of the movable frames is fixedly connected to the top of the baffle, and a knob is fixed to one end of the bidirectional screw.
[0008] Furthermore, a guide groove is provided at the top center of the housing, and a slider that slides in the guide groove is fixed to the top of the movable frame.
[0009] Furthermore, each of the baffles is provided with a connection hole, and a sealing ring is fixed to the inner wall of each connection hole. Both the sealing ring and the connection hole are designed in the shape of an "8". The sealing ring is attached to the outer wall of the glue roller and the glue coating roller.
[0010] Furthermore, each side of the baffle is rotatably provided with guide rollers that are equally spaced and distributed in an arc shape, and the height of the guide rollers gradually decreases, with the bottom of the lowest guide roller being flush with the bottom of the glue-applying roller.
[0011] Furthermore, the drive mechanism includes a side frame fixedly installed on the outer wall of one side of the housing, and a worm gear rotatably connected to the inner wall of the side frame. A drive motor for driving the worm gear to rotate is fixedly installed at one end of the side frame. A worm wheel is fixedly installed at one end of each conveying roller, and the worm wheel meshes with the worm gear. One end of one of the conveying rollers is also fixedly installed with a drive gear, and a first driven gear is fixedly installed at one end of the glue-applying roller, which meshes with the drive gear. A second driven gear is fixedly installed at one end of the glue-applying roller, and the second driven gear meshes with the first driven gear.
[0012] Furthermore, an installation groove is provided at the middle of the bottom of the housing, and a leakage collection box is fixedly installed on the inner wall of the installation groove. A discharge pipe is fixedly installed at the bottom of the leakage collection box, and a discharge valve is fixedly installed at the bottom of the discharge pipe. A support frame is fixedly installed at the bottom of the housing.
[0013] Furthermore, the top of the inner wall of the leakage collection box is fixedly installed with scraper seats that are evenly distributed, and one side of the top of the scraper seat is attached to the outer wall of the conveying roller, while the other side of the scraper seat is designed as an inclined surface.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] In this invention, the bidirectional screw, movable frame, and sealing ring within the spacing adaptation mechanism work together to eliminate the need to disassemble core components such as the coating roller, gluing roller, or glue delivery pipe. Simply turning a knob drives the two baffles to move closer or further apart synchronously, quickly adjusting the coating width to match different specifications of cardboard. Compared to the cumbersome operation of "disassembling and replacing parts" in existing equipment, this significantly shortens the changeover adjustment time, effectively solving the problems of "difficult adjustment and low efficiency" when processing multi-specification cardboard, and significantly improving the flexibility and continuity of the production line.
[0016] In this invention, the spacing adaptation mechanism can precisely control the glue application range to match the width of the cardboard, avoiding waste caused by glue exceeding the edge of the cardboard. At the same time, the leakage collection box at the bottom of the equipment and the scraper seat form a closed-loop recycling system. The scraper seat scrapes off the glue residue on the outer wall of the conveyor roller in real time. The scraped glue slides down the inclined surface of the scraper seat into the leakage collection box, and is then recycled and reused through the discharge pipe and discharge valve, thereby significantly reducing the glue loss rate.
[0017] In this invention, the height of the arc-shaped guide rollers on one side of the baffle gradually decreases, and the lowest point is flush with the bottom of the coating roller, which can guide and limit the paperboard to prevent the paperboard from shifting during the conveying and coating process, and ensure accurate coating position.

[0024] 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.
[0025] Please see Figures 1-5In this embodiment of the present invention, a processing equipment for cardboard production includes a housing 1. A coating roller 11 is rotatably connected to the inner wall of the housing 1 near the center, and an upper coating roller 8 is rotatably connected to the inner wall of the housing 1 near the coating roller 11. A glue feeding pipe 9 is fixedly installed on the housing 1, and the glue feeding pipe 9 is located above the gap between the coating roller 11 and the upper coating roller 8. Baffles 61 are sleeved on both sides of the outer walls of the glue feeding pipe 9 and the coating roller 11. A spacing adaptation mechanism 6 for adjusting the distance between the two baffles 61 is provided on the housing 1. The spacing adaptation mechanism 6 includes a bidirectional screw 62 rotatably installed on the inner wall of the top of the housing 1, and movable frames 63 are screwed to both ends of the bidirectional screw 62. The bottom of the movable frame 63 is fixedly connected to the top of the baffle 61. A knob 64 is fixed to one end of the bidirectional screw 62. A guide groove is provided in the middle of the top of the housing 1. 65, and the top of the movable frame 63 is fixed with a slider that slides in the guide groove 65. The baffles 61 are all provided with connection holes 66, and the inner wall of the connection holes 66 is fixed with a sealing ring 67. The sealing ring 67 and the connection hole 66 are both designed in the shape of "8". The sealing ring 67 is attached to the outer wall of the gluing roller 8 and the coating roller 11. The housing 1 is rotatably provided with conveyor rollers 2 that are evenly distributed. One end of the conveyor roller 2, the gluing roller 8 and the coating roller 11 is provided with a drive mechanism 4. Rotating the knob 64 drives the bidirectional screw 62 to rotate, which drives the movable frames 63 on both sides to slide along the guide groove 65, thereby adjusting the distance between the two baffles 61, so that the glue is evenly attached to the surface of the coating roller 11 only within the set width, thereby quickly adjusting the coating width to match different specifications of cardboard, effectively solving the problem of "difficult adjustment and low efficiency" when processing multi-specification cardboard.
[0026] Specifically, guide rollers 10 are rotatably arranged at equal intervals in an arc shape on one side of the baffle 61, and the height of the guide rollers 10 gradually decreases. The bottom of the guide roller 10 at the lowest point is flush with the bottom of the glue coating roller 11. The guide rollers 10 guide and limit the paperboard to prevent the paperboard from deviating.
[0027] Specifically, the drive mechanism 4 includes a side frame 5 fixedly installed on the outer wall of one side of the housing 1, and a worm gear 42 rotatably connected to the inner wall of the side frame 5. A drive motor 41 for driving the worm gear 42 to rotate is fixedly installed at one end of the side frame 5. A worm wheel 43 is fixedly installed at one end of each conveying roller 2, and the worm wheel 43 meshes with the worm gear 42. A drive gear 45 is also fixedly installed at one end of one of the conveying rollers 2, and a first driven gear 44 is fixedly installed at one end of the glue coating roller 11, which meshes with the drive gear 45. A second driven gear 46 is fixedly installed at one end of the glue application roller 8, and the second driven gear 46 meshes with the first driven gear 44. The drive motor 41 drives the worm gear 42 to rotate, and the worm gear 42 drives all the conveying rollers 2 to rotate synchronously by meshing with the worm wheel 43. At the same time, it drives the glue coating roller 11 and the glue application roller 8 to rotate synchronously, realizing the linkage operation of the conveying and glue application components.
[0028] Specifically, an installation groove is provided in the middle of the bottom of the housing 1, and a leakage collection box 7 is fixedly installed on the inner wall of the installation groove. A discharge pipe is fixedly installed at the bottom of the leakage collection box 7, and a discharge valve 12 is fixedly installed at the bottom of the discharge pipe. A support frame 3 is fixedly installed at the bottom of the housing 1. Equally spaced scraper seats 13 are fixedly installed on the top of the inner wall of the leakage collection box 7. One side of the top of the scraper seat 13 is attached to the outer wall of the conveying roller 2, and the other side of the scraper seat 13 is designed as a slope. During the operation of the conveying roller 2, the glue remaining on its outer wall will be scraped off by the scraper seat 13. The scraped glue slides into the leakage collection box 7 along the slope of the scraper seat 13. When the collected glue reaches a certain amount, the discharge valve 12 is opened, and the glue is discharged through the discharge pipe for recycling and reuse, thus realizing the recycling of waste materials.
[0029] The working principle of this utility model is as follows: When working, the drive motor 41 first starts and drives the worm 42 to rotate. The worm 42 drives all the conveying rollers 2 to rotate synchronously by meshing with the worm wheel 43. At the same time, one of the conveying rollers 2 drives the drive gear 45 to rotate. The drive gear 45 meshes with the first driven gear 44 and then drives the glue coating roller 11 to rotate. The first driven gear 44 then meshes with the second driven gear 46 and drives the glue application roller 8 to rotate synchronously, so as to realize the linkage operation of the conveying and glue coating components.
[0030] Next, the cardboard to be processed is placed on the conveyor roller 2 and conveyed forward. Before entering the gluing area, the arc-shaped guide roller 10, whose height gradually decreases on one side of the baffle 61 and whose lowest point is flush with the bottom of the gluing roller 11, guides and limits the cardboard to prevent it from deviating and ensures that it enters accurately between the gluing roller 11 and the glue roller 8.
[0031] Then, according to the width of the cardboard, the knob 64 is turned to drive the bidirectional screw 62 to rotate. The bidirectional screw 62 drives the movable frames 63 on both sides to slide along the guide groove 65, thereby adjusting the distance between the two baffles 61. Then, the glue supply tube 9 supplies glue to the gap between the glue coating roller 11 and the top glue roller 8. The figure-eight sealing ring 67 fixed in the connection hole 66 of the baffle 61 fits against the outer wall of the top glue roller 8 and the glue coating roller 11 to seal and limit the glue liquid, so that the glue liquid is only evenly attached to the surface of the glue coating roller 11 within the set width. Then, the glue coating roller 11 evenly coats the glue liquid on the surface of the cardboard.
[0032] Finally, during the operation of the conveyor roller 2, the glue residue on its outer wall will be scraped off by the scraper seat 13 fixed to the top of the inner wall of the leakage collection box 7. The scraped glue will slide into the leakage collection box 7 along the inclined surface of the scraper seat 13. When the collected glue reaches a certain amount, the discharge valve 12 will be opened and the glue will be discharged through the discharge pipe for recycling and reuse, thus completing the entire processing and waste recycling process.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
