Description

Technical Field

[0001] This invention belongs to the field of adhesive coating equipment technology, and specifically relates to a multifunctional corrugated paper adhesive coating device. Background Technology

[0002] Corrugated cardboard is widely used in production and daily life due to its advantages such as low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. The production of corrugated cardboard involves pressing the base paper into corrugations, applying glue, and bonding. This process requires applying glue to the corrugated paper before laminating it with the face paper. Most corrugated paper gluing devices involve partially immersing the gluing roller in a glue box, and then applying glue to the pressed base paper by the rotation of the roller. However, existing gluing devices are limited in function and cannot simultaneously apply glue to corrugated paper of different widths and thicknesses, resulting in low equipment applicability and increased production costs. Furthermore, existing glue boxes make it inconvenient to stir the glue during the gluing process, causing the glue to solidify easily, thus affecting the bonding effect on the corrugated paper.

[0003] For example, invention patent application number CN202111435130.4 specifically discloses a gluing and bonding equipment for corrugated paper production and processing. The technical solution includes: a support frame, which is installed on the top of the worktable; a transmission roller, which is disposed inside the support frame and located above the worktable; and a gluing roller, which is disposed inside the support frame and located above the transmission roller. This invention, by setting an adjustment mechanism, rotates a bidirectional lead screw, which causes two collars and baffles to move relative to each other, thereby reducing the contact width between the gluing roller and the bottom of the glue storage bin. This allows for adjustment of the distance between the baffles and collars according to the width of the corrugated cardboard. The rotation of the gluing roller is used to apply glue to corrugated cardboard of different widths. In addition, a stirring mechanism is provided to prevent the glue from solidifying. However, the invention has shortcomings. For example, it cannot apply glue to corrugated cardboard of different thicknesses, the adjustable width range is small, the adjustment mechanism and stirring mechanism are too complicated, the lead screw bears multiple loads and has a large lateral span, and even small deformations may cause the device to jam, resulting in insufficient stability and affecting the actual use value of the equipment.

[0004] Therefore, in view of the above-mentioned shortcomings, this application proposes a multifunctional corrugated paper coating device that can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multifunctional corrugated paper coating device, thereby effectively solving the problems existing in the prior art.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows:

[0007] A multifunctional corrugated paper coating device includes a frame, a conveyor roller, a coating roller, a lifting device, a coating unit, an adjusting device, and a stirring device. The conveyor roller is rotatably connected to the frame. The coating roller is mounted on the frame via the lifting device and is located directly above the conveyor roller. The coating unit is mounted above the coating roller. The positions of the coating unit and the coating roller remain relatively fixed. When the coating roller moves up and down with the lifting device, the coating unit also moves synchronously. The coating unit is equipped with an adjusting device for adjusting the contact width between the glue and the coating roller. A stirring device is rotatably installed inside the coating unit. The stirring device is connected to the coating roller via a pulley device and rotates synchronously with the coating roller to prevent the glue from solidifying.

[0008] As a further provision of the above solution, the lifting device includes a sliding plate, guide rails, and a support bearing. The guide rails are fixedly mounted on the frame in a parallel and vertically upward manner. The sliding plate is slidably connected between the guide rails. The support bearing is fixedly mounted on the sliding plate. The glue-applying roller is rotatably connected to the lifting device through the support bearing.

[0009] As a further feature of the above solution, the upper end of the lifting device is provided with a telescopic rod device, which includes a telescopic rod, a connecting frame and a spring. The connecting frame is fixedly connected to the slide plate, and the spring on the connecting frame serves as a buffer and shock absorber. The upper part of the connecting frame is provided with a telescopic rod. When the telescopic rod extends or retracts, it drives the lifting device to move up and down, thereby changing the position of the coating roller and the coating device, so that the equipment can perform coating operations on corrugated paper of different thicknesses.

[0010] As a further provision of the above solution, the glue application device includes a glue box, a first partition, and a second partition. The glue box has a rectangular parallelepiped structure, and a rectangular slot is formed in the bottom plate of the glue box. The glue application roller extends into the glue box through the rectangular slot and contacts the glue. The glue box is fixedly mounted on a support platform by a mounting plate. The support platform is located directly behind the glue application roller and can be raised and lowered synchronously with the lifting device to ensure the relatively fixed position of the glue application device and the glue application roller. The glue box includes a box body, slide rails, and mounting blocks. Cylindrical slide rails are provided at the four long edges of the box body, and mounting blocks are provided on the upper part of the two side plates of the box body. The first partition is a rectangular plate in general, and the upper part of the first partition has a... The first screw block has a first partition block at its lower part. The first partition block is arc-shaped and symmetrically distributed on the lower end surface of the first partition. The first partition block is coaxial with the glue roller and slides in contact with it. The second partition is a rectangular plate with the same dimensions as the first partition. The second partition has a second screw block on its side and a second partition block at its lower part. The second partition block has the same dimensions as the first partition block. The first partition and the second partition have the same first and second sliding grooves, respectively. The first partition and the second partition are slidably mounted on the glue box through the first and second sliding grooves. The first and second sliding grooves cooperate with the slide rail, side plate and bottom plate on the glue box.

[0011] As a further feature of the above solution, the lower ends of the first and second partitions are provided with arc-shaped notches. The notches are coaxial with the glue-applying roller and slide in contact with it. There are two first partitions installed at both ends of the glue box. There are also two second partitions located between the first partitions. A main glue compartment is formed between the two second partitions, and two secondary glue compartments are formed between the first and second partitions. By adjusting the position of the partitions, the width and position of the main and secondary glue compartments in the glue box can be changed, so as to achieve contact between the glue-applying roller and the glue at any position and with any width.

[0012] The first and second partitions have through holes at their centers. A slip ring is rotatably installed in the through hole. The slip ring is cylindrical and has a keyway-type through groove in its center. The slip ring only rotates within the through hole and will not move to the left or right and disengage from the through hole.

[0013] As a further provision of the above solution, the adjusting device includes a first lead screw, a second lead screw, a third lead screw, a fourth lead screw, and a bracket. The bracket is L-shaped and installed at the center of the support platform. The horizontal section of the bracket is located above the glue box and perpendicular to the glue box. The first lead screw and the second lead screw are coaxially mounted on the first screw block of the first partition plate. One end of the first lead screw is rotatably connected to the left mounting plate and the other end is rotatably connected to the bracket. One end of the second lead screw is rotatably connected to the right mounting plate and the other end is rotatably connected to the bracket. A transmission gear is installed at the end of the first and second lead screws near the bracket. Driving the transmission gear causes the lead screw to rotate, thereby causing the first partition plate to slide on the glue box.

[0014] The third and fourth lead screws are coaxially mounted on the second screw block of the second partition plate. One end of the third lead screw is rotatably connected to the left mounting plate and the other end is rotatably connected to the bracket. One end of the fourth lead screw is rotatably connected to the right mounting plate and the other end is rotatably connected to the bracket. A transmission gear is installed at the end of the third and fourth lead screws near the bracket. The transmission gear drives the lead screw to rotate, thereby causing the second partition plate to slide on the plastic box. The four lead screws can rotate independently, which provides high adjustment flexibility. Moreover, the lead screw span is halved, resulting in higher structural stability.

[0015] As a further feature of the above scheme, the stirring device is located at the center of the glue box. The stirring device includes a stirring shaft and stirring units. One end of the stirring shaft is connected to a pulley device. The stirring shaft is a cylindrical shaft with guide protrusions parallel to the axis on its surface. The stirring units are slidably mounted on the stirring shaft. The stirring units have grooves that mate with the guide protrusions and also have outwardly radiating interference columns. Limiting platforms are provided on both sides of the stirring units along the stirring shaft direction. Three sets of stirring units are provided, located in the main glue compartment and the auxiliary glue compartment respectively. The guide protrusions on the stirring shaft mate with the through grooves of the slip ring, so that the rotation of the stirring shaft will not affect the partition, and the lateral displacement of the partition will not interfere with the rotation of the stirring shaft. When the stirring shaft rotates, it drives the stirring units to rotate together. When the position of the partition is adjusted, the partition contacts the limiting platforms, which will drive the stirring units to slide on the rotating shaft, realizing the automatic adjustment of the stirring device. In addition, the limiting platforms also serve to prevent the partition from colliding.

[0016] The beneficial effects of this invention are:

[0017] After starting the equipment, adjust the partitions and coating rollers to the required positions based on the width, thickness, and coating area of ​​the corrugated paper to be coated, using the adjusting and lifting devices. When the thickness of the corrugated paper changes, activate the telescopic rod device to move the slide plate to the desired position, thereby driving the coating roller upward and increasing the gap between the coating roller and the conveying roller. When it is necessary to coat the entire surface of the corrugated paper, adjust the first and second lead screws so that the first partition moves to the extreme positions on both sides of the glue tank. Adjust the third and fourth lead screws to change the width of the main glue tank, injecting glue only into the main glue tank to coat the corrugated paper. When it is necessary to coat a specific area of ​​the corrugated paper, simultaneously adjust the first, second, third, and fourth lead screws to change the width of the secondary glue tank and its position on the coating roller to achieve area coating of the corrugated paper. When adjusting the partitions, the stirring unit will rotate and slide along the stirring shaft to adjust its position. The stirring device and the coating roller rotate synchronously to ensure that the glue does not solidify.

[0018] This invention utilizes the cooperation between a lifting device, a gluing device, an adjusting device, and a stirring device to apply glue to corrugated paper of different widths and thicknesses. It is also applicable to production processes involving partial gluing. It is versatile in function, simple and reliable in structure, and has low maintenance costs, meeting actual production needs.

[0029] like Figure 1 , Figure 2 As shown, this embodiment discloses a multifunctional corrugated paper coating device, including a frame 1, a conveyor roller 3, a coating roller 4, a lifting device, a coating device, an adjusting device, and a stirring device. The conveyor roller 3 is rotatably connected to the frame 1. The coating roller 4 is mounted on the frame via the lifting device and is located directly above the conveyor roller 3. The coating device is mounted above the coating roller 4. The positions of the coating device and the coating roller 4 are always kept relatively fixed. An adjusting device is provided on the coating device. A stirring device is rotatably installed inside the coating device. The stirring device 14 is connected to the coating roller 4 via a pulley device 6. The stirring device 14 rotates synchronously with the coating roller. The coating device is fixedly mounted on a support platform 18 via a mounting plate 15. The support platform 18 is located directly behind the coating roller 4 and can be raised and lowered synchronously with the lifting device to ensure the relatively fixed position of the coating device and the coating roller 4. The adjusting device is rotatably connected to the bracket 12 and the coating device.

[0030] like Figure 3 As shown, the lifting device includes a slide plate 501, a guide rail 502, and a support bearing 503. The guide rails 502 are fixedly mounted on the frame 1, parallel to each other and vertically upward. The slide plate 501 is slidably connected between the guide rails 502. The support bearing 503 is fixedly mounted on the slide plate 501. The glue roller 4 is rotatably connected to the lifting device through the support bearing 503.

[0031] The upper end of the lifting device is equipped with a telescopic rod device 7, which includes a telescopic rod 701, a connecting frame 702, and a spring 703. The connecting frame 702 is fixedly connected to the slide plate 501. The spring 703 is provided on the connecting frame 702 to buffer and dampen shock. The telescopic rod 701 is fixedly connected to the upper part of the connecting frame 702. When the telescopic rod 701 extends or retracts, it drives the lifting device to move up and down, thereby changing the position of the coating roller 4 and the coating device, so that the equipment can perform coating operations on corrugated paper of different thicknesses.

[0032] like Figure 4 , Figure 5As shown, the glue application device includes a glue box 8, a first partition 9, and a second partition 10. The glue box 10 has a rectangular parallelepiped structure. The bottom plate of the glue box 10 has a rectangular slot. The glue application roller 4 extends into the glue box 10 through the rectangular slot and contacts the glue. The glue box 10 is fixedly mounted on a support platform 18 by a mounting plate 15. The support platform 18 is located directly behind the glue application roller 4 and can be raised and lowered synchronously with the lifting device to ensure the relatively fixed position of the glue application device and the glue application roller 4. The glue box 10 includes a box body 801, a slide rail 802, and a mounting block 803. The four long edges of the box body 10 are provided with cylindrical slide rails 802, and the upper part of the two side plates of the box body 10 is provided with mounting blocks 803. The first partition 9 is a rectangular plate in general. The upper part of the first partition 9 is provided with a first screw block 901, and the lower part is provided with a first dividing block 901. 3. The first partition block 903 is arc-shaped and symmetrically distributed on the lower end face of the first partition plate 9. The first partition block 903 is coaxial with the glue roller 4 and slides in contact with it. The second partition plate 10 is a rectangular plate with the same dimensions as the first partition plate 9. The second partition plate 10 has a second screw block 1001 on its side and a second partition block 1003 at its bottom. The dimensions of the second partition block 1003 are the same as those of the first partition block 903. The first partition plate 9 and the second partition plate 10 have the same first sliding groove 902 and second sliding groove 1002 respectively. The first partition plate 9 and the second partition plate 10 are slidably mounted on the glue box 8 through the first sliding groove 902 and the second sliding groove 1002. The first sliding groove 902 and the second sliding groove 1002 slide in cooperation with the slide rail 802, side plate and bottom plate on the glue box 8.

[0033] The lower ends of the first partition 9 and the second partition 10 have arc-shaped notches. The notches are coaxial with the glue-applying roller 4 and slide in contact with it. There are two first partitions 9, which are installed in the two end areas of the glue box 8. There are also two second partitions 10, which are located between the first partitions 9. A main glue chamber is formed between the two second partitions 10, and two secondary glue chambers are formed between the first partitions 9 and the second partitions 10. By adjusting the position of the partitions, the width of the main glue chamber and the secondary glue chamber and their position in the glue box can be changed, so as to achieve contact between the glue-applying roller and the glue at any position and any width.

[0034] The adjustment device includes a first lead screw 11, a second lead screw 13, a third lead screw 16, a fourth lead screw 17, and a bracket 12. The bracket 12 is L-shaped and installed at the center of the support platform 18. The horizontal section of the bracket 12 is located above the glue box 8 and is perpendicular to the glue box 8. The first lead screw 11 and the second lead screw 13 are coaxially installed on the first screw block 901 of the first partition plate 9. One end of the first lead screw 11 is rotatably connected to the left mounting plate 15 and the other end is rotatably connected to the bracket 12. One end of the second lead screw 13 is rotatably connected to the right mounting plate 15 and the other end is rotatably connected to the bracket 12. A transmission gear 19 is installed at the end of the first lead screw 11 and the second lead screw 13 near the bracket 12. Driving the transmission gear 19 causes the lead screw to rotate, thereby causing the first partition plate 9 to slide on the glue box 8.

[0035] The third lead screw 16 and the fourth lead screw 17 are coaxially mounted on the second screw block 1001 of the second partition plate 10. One end of the third lead screw 16 is rotatably connected to the left mounting plate 15 and the other end is rotatably connected to the bracket 12. One end of the fourth lead screw 17 is rotatably connected to the right mounting plate 15 and the other end is rotatably connected to the bracket 12. A transmission gear 19 is installed at the end of the third lead screw 16 and the fourth lead screw 17 near the bracket 12. Driving the transmission gear 19 causes the lead screw to rotate, thereby causing the second partition plate 10 to slide on the plastic box 8. The four lead screws can rotate independently, which provides high adjustment flexibility. Moreover, the lead screw span is halved, resulting in higher structural stability.

[0036] like Figure 6 , Figure 7 As shown, a through hole is opened at the center of the first partition 9 and the second partition 10. A slip ring 20 is rotatably installed in the through hole. The slip ring 20 is cylindrical and has a keyway-type through groove 2001 in the center. The slip ring 20 only rotates in the through hole and will not move to the left or right and disengage from the through hole.

[0037] The stirring device 14 is located at the center of the plastic box 8. The stirring device 14 includes a stirring shaft 1401 and a stirring unit 1403. One end of the stirring shaft 1401 is connected to the pulley device 6. The stirring shaft 1401 is a cylindrical shaft with guide protrusions 1402 parallel to the axis on its surface. The stirring unit 1403 is slidably mounted on the stirring shaft 1401. The stirring unit 1403 has a groove 1403-1 that mates with the guide protrusions 1402. It also has outwardly radiating interference columns 1403-2. Limiting platforms 1403-3 are provided on both sides of the stirring unit 1403 along the direction of the stirring shaft 1401. Three sets of 403 are set up, located in the main glue tank and the auxiliary glue tank respectively; the guide protrusion 1402 on the stirring shaft 1401 cooperates with the through groove 2001 of the slip ring 20, so that the rotation of the stirring shaft 1401 will not affect the partition, and the left and right displacement of the partition will not interfere with the rotation of the stirring shaft 1401. When the stirring shaft 1401 rotates, it drives the stirring unit 1403 to rotate together. When the position of the partition is adjusted, the partition contacts the limiting platform 1403-3, which will drive the stirring unit 1403 to slide on the rotating shaft 1401, realizing the automatic adjustment of the stirring device 14. In addition, the limiting platform 1403-3 also plays a role in preventing the partition from colliding.

[0038] The working principle of this invention is as follows: Based on the width, thickness, and glue application area of ​​the corrugated paper to be glued, the adjusting and lifting devices are flexibly used to adjust the partition and glue application roller to the required positions to achieve the desired glue application. When the thickness of the corrugated paper changes, the telescopic rod device 7 is activated, moving the slide plate 501 up or down to the desired position, thereby moving the glue application roller 4 and changing the gap between the glue application roller 4 and the conveying roller 3. When it is necessary to apply glue to the entire surface of the corrugated paper, the first lead screw 11 and the second lead screw 13 are adjusted so that the first partition 9 moves to the extreme positions on both sides of the glue tank 8. The third lead screw 16 and the fourth lead screw 17 are adjusted to change the width of the main glue tank. Then, only glue is injected into the main glue tank to apply glue to the corrugated paper, which can be used for different widths of corrugated paper. The corrugated paper is coated with glue. When it is necessary to apply glue to a specific area of ​​the corrugated paper, the first lead screw 11, the second lead screw 13, the third lead screw 16, and the fourth lead screw 17 are adjusted simultaneously to change the width of the main glue bin and the position of the main glue bin above the glue coating roller 4. Glue is added to the glue bin as needed to achieve area-by-area glue application to the corrugated paper. When the partition is adjusted, the stirring unit 1403 will rotate and slide along the stirring shaft 1401 to adjust its position. The stirring device 14 rotates synchronously with the glue coating roller 4 to ensure that the glue does not solidify.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the scope of the invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
