Description

Technical Field

[0001] This utility model relates to the field of paper pressing in paper mounting machines, and in particular to an auxiliary device for paper pressing in paper mounting machines used in the production of honeycomb cardboard. Background Technology

[0002] Currently, Chinese utility model patent CN222875497U discloses a paper pressing auxiliary device for a laminating machine. While this auxiliary device facilitates cleaning during paper jams by moving the cylinder-driven paper pressing rollers up and down, it has other problems during use. For example, the spacing between the side pressing rollers cannot be adjusted. The device consists of one central pressing roller and two side pressing rollers. The side pressing rollers need to be moved above the sides of the honeycomb paperboard during use. Because the rollers are fixedly installed, they are not suitable for processing various paperboard specifications, resulting in poor flexibility. Furthermore, they lack adaptive adjustment capabilities. The up and down movement of the rollers relies entirely on cylinder drive, and all rollers share a single adjustment component. When there is a difference in height between the center and sides of the honeycomb paperboard, it can lead to over-pressing on the sides or incomplete pressing in the center. To solve these problems, we propose a paper pressing auxiliary device for a laminating machine used in the production of honeycomb paperboard. Utility Model Content

[0003] The purpose of this invention is to provide a paper pressing auxiliary device for a laminating machine used in the production of honeycomb paperboard, which solves the problem that existing paper pressing auxiliary devices cannot adjust the spacing of the side pressing rollers and do not have an adaptive adjustment function.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A paper pressing auxiliary device for a laminating machine used in the production of honeycomb paperboard includes a support frame, a cylinder is bolted through the top of the support frame, a housing is installed at the piston end of the cylinder, a bidirectional screw is rotatably connected inside the housing, two threaded plates are threadedly connected to the surface of the bidirectional screw, a first fixed cylinder is installed at the bottom of the threaded plates, a second fixed cylinder is installed at the bottom of the housing, a moving block is provided inside both the first and second fixed cylinders, a limit spring is installed at the top of the moving block and between the first and second fixed cylinders, a connecting rod is bolted to the bottom of the moving block, a pressure roller is rotatably connected to the surface of the roller on the side of the connecting rod, and a correction mechanism is provided inside the support frame.

[0005] The above technical solution allows for easy adjustment of the spacing between the side pressure rollers, making operation simple and convenient, improving the applicability and flexibility of the equipment. It also has an adaptive adjustment function, which can be used to press paperboard of different thicknesses, avoiding excessive pressure on the sides or insufficient pressure in the middle, making it highly practical.

[0006] The present invention is further configured such that: the correction mechanism includes correction plates, the number of correction plates is two, the bottom of the two correction plates is provided with through grooves, the opposite sides of the two correction plates are rotatably connected with threaded rods, the other end of the threaded rods extends through to the outside of the bracket and is equipped with a first throttle handle, and threaded grooves are provided on both sides of the bracket.

[0007] By adopting the above technical solution, the honeycomb paperboard on the mounting machine table below can be guided by the setting of the correction plate, threaded rod and first throttle, so as to avoid the honeycomb paperboard from deviating during the conveying process.

[0008] The present invention is further configured such that: a slide rail is bolted inside the housing, and a slider that is slidably connected to the slide rail is welded to the top of the threaded plate.

[0009] By adopting the above technical solution, the threaded plate can be limited by the setting of slide rail and slider, preventing the threaded plate from flipping over during left and right movement.

[0010] The present invention is further configured such that: the other end of the bidirectional screw extends through to the outside of the housing and is equipped with a second throttle.

[0011] By adopting the above technical solution and setting the second throttle, it is easy for personnel to rotate the bidirectional screw by hand.

[0012] The present invention is further configured such that a damper is installed on the top of the moving block and between the first fixed cylinder and the second fixed cylinder.

[0013] By adopting the above technical solution, the damper can be used to suppress the jumping of the limit spring, consume the kinetic energy stored in the limit spring, and improve stability.

[0014] The present invention is further configured such that: mounting plates are welded to both sides of the bracket, and mounting holes are provided on the top of the mounting plates.

[0015] By adopting the above technical solution, the mounting plate and mounting holes make it easy for personnel to fix the bracket to the mounting machine table with screws.

[0016] The present invention is further configured such that: a guide rod is installed on the front side of the movable block, and sliding grooves are provided on the front sides of both the first fixed cylinder and the second fixed cylinder, and the other end of the guide rod extends to the outside of the sliding groove.

[0017] By adopting the above technical solution, the guide rod and sliding groove can limit the movement of the moving block and improve the stability of the moving block during its up and down movement.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model first fixes the bracket to the designated position with screws. After the bracket is fixed, the second throttle is held by hand to drive the bidirectional screw to rotate. When the bidirectional screw rotates, it will drive the two threaded plates to move outward synchronously through the cooperation of the slide rail and the slider. When the threaded plates move outward, they will drive the first fixed cylinder and the lower pressure roller to be above the side of the cardboard. This makes it easy for personnel to adjust the spacing of the side pressure rollers. The operation is simple and convenient, and improves the applicability and flexibility of the equipment.

[0020] 2. This utility model uses a starting cylinder to move the housing downwards. When the housing moves downwards, it moves the pressure roller down with it to contact the machine base. When the cardboard is conveyed from back to front, it passes over the pressure roller. When the cardboard passes over the pressure roller, it pushes the pressure roller and connecting rod upwards. When the connecting rod moves upwards, it causes the moving block to squeeze against the limit spring and damper. Because the limit spring is elastic, when the limit spring contracts, it pushes the pressure roller in the opposite direction to fit tightly against the cardboard. It has an adaptive adjustment function and can be used to press cardboard of different thicknesses, avoiding over-pressure on the side or incomplete pressure in the middle. It is highly practical.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] refer to Figure 1 , Figure 2 and Figure 3A paper pressing auxiliary device for a laminating machine used in the production of honeycomb cardboard includes a support 1. A cylinder 2 is bolted through the top of the support 1. A housing 3 is installed on the piston end of the cylinder 2. A bidirectional screw 4 is rotatably connected inside the housing 3. Two threaded plates 5 are threadedly connected to the surface of the bidirectional screw 4. A first fixed cylinder 6 is installed at the bottom of the threaded plates 5, and a second fixed cylinder 7 is installed at the bottom of the housing 3. The support 1 is first fixed to a designated position with screws. After the support 1 is fixed, the second throttle 15 is held by hand to drive the bidirectional screw 4 to rotate. When the bidirectional screw 4 rotates, it drives the two threaded plates 5 to move outward synchronously through the cooperation of the slide rail 13 and the slider 14. When the threaded plates 5 move outward, they drive the first fixed cylinder 6 and the lower pressure roller 11 to be above the side of the cardboard, which makes it easy for personnel to adjust the spacing of the side pressure rollers 11. The operation is simple and convenient, improving the applicability and flexibility of the equipment.

[0028] refer to Figure 2 The housing 3 is bolted with a slide rail 13, and the top of the threaded plate 5 is welded with a slider 14 that is slidably connected to the slide rail 13. The slide rail 13 and the slider 14 can limit the threaded plate 5 and prevent the threaded plate 5 from flipping over during left and right movement.

[0029] refer to Figure 2 The other end of the bidirectional screw 4 extends through the outside of the housing 3 and is equipped with a second throttle 15. The second throttle 15 allows personnel to easily rotate the bidirectional screw 4 by hand.

[0030] refer to Figure 1 and Figure 2 Mounting plates 17 are welded to both sides of the bracket 1. Mounting plates 17 have mounting holes on their tops. The mounting plates 17 and mounting holes make it easy for personnel to fix the bracket 1 to the mounting machine table with screws.

[0031] Brief description of the usage process: First, fix the bracket 1 to the designated position with screws. After the bracket 1 is fixed, hold the second throttle 15 and drive the bidirectional screw 4 to rotate. When the bidirectional screw 4 rotates, it will drive the two threaded plates 5 to move outward synchronously through the cooperation of the slide rail 13 and the slider 14. When the threaded plates 5 move outward, they will drive the first fixed cylinder 6 and the lower pressure roller 11 to be above the side of the cardboard.

[0032] Example 2:

[0033] refer to Figure 1 , Figure 2 and Figure 3A paper pressing auxiliary device for a laminating machine used in the production of honeycomb paperboard includes a movable block 8 inside both the first fixed cylinder 6 and the second fixed cylinder 7. Limit springs 9 are installed on the top of the movable block 8 and between the first and second fixed cylinders 6 and 7. A connecting rod 10 is bolted to the bottom of the movable block 8. A pressure roller 11 is rotatably connected to the side roller surface of the connecting rod 10. A correction mechanism 12 is installed inside the support 1. A starting cylinder 2 drives the housing 3 to move downwards, which in turn drives the pressure roller 11 downwards. When the cardboard is conveyed from the rear to the front, it will pass through the pressure roller 11. When the cardboard passes through the pressure roller 11, it will push the pressure roller 11 and the connecting rod 10 upward. When the connecting rod 10 moves upward, it will drive the moving block 8 to squeeze the limit spring 9 and the damper 16. Since the limit spring 9 is elastic, when the limit spring 9 contracts, it will push the pressure roller 11 in the opposite direction to fit tightly with the cardboard. It has an adaptive adjustment function and can be used to press cardboard of different thicknesses to avoid over-pressure on the side or incomplete pressure in the middle. It is highly practical.

[0034] refer to Figure 1 and Figure 2 The correction mechanism 12 includes two correction plates 122. Each correction plate 122 has a through groove at its bottom. Each correction plate 122 has a threaded rod 121 rotatably connected to its opposite side. The other end of the threaded rod 121 extends through to the outside of the bracket 1 and is equipped with a first rotary handle 123. Threaded grooves are provided on both sides of the bracket 1. Through the setting of the correction plates 122, threaded rods 121 and first rotary handles 123, the honeycomb paperboard on the mounting machine table below can be guided to avoid the honeycomb paperboard from shifting during the conveying process.

[0035] refer to Figure 3 A damper 16 is installed on the top of the moving block 8 and between the first fixed cylinder 6 and the second fixed cylinder 7. The damper 16 can be used to suppress the jumping of the limit spring 9, consume the kinetic energy stored in the limit spring 9, and improve stability.

[0036] refer to Figure 1 A guide rod 18 is installed on the front of the movable block 8. The first fixed cylinder 6 and the second fixed cylinder 7 are both provided with sliding grooves on their front sides. The other end of the guide rod 18 extends to the outside of the sliding groove. By setting the guide rod 18 and the sliding groove, the movable block 8 can be limited, thereby improving the stability of the movable block 8 during the up and down movement.

[0037] Brief description of the operation: The start cylinder 2 drives the housing 3 to move down. When the housing 3 moves down, it will drive the pressure roller 11 to move down together and contact the machine. When the cardboard is conveyed from the rear to the front, it will pass through the pressure roller 11. When the cardboard passes through the pressure roller 11, it will push the pressure roller 11 and the connecting rod 10 upward. When the connecting rod 10 moves upward, it will drive the moving block 8 to squeeze the limit spring 9 and the damper 16. Since the limit spring 9 is elastic, when the limit spring 9 contracts, it will push the pressure roller 11 in the opposite direction to fit tightly with the cardboard.
