Description

Technical Field

[0001] This utility model relates to the field of paperboard processing, and in particular to a pressing device for paperboard processing. Background Technology

[0002] Paperboard lamination is a manufacturing process that bonds multiple layers of paperboard together by applying pressure. It is mainly used to produce composite paperboard materials with stronger structure and more stable performance, as well as paper products such as cat scratching boards. Specialized cold pressing equipment is generally used when laminating paperboard.

[0003] Currently, some cold pressing equipment for paperboard lamination still has certain shortcomings in actual use: When traditional multi-layer paperboard is pressed, workers usually neatly stack the paperboard from one side of the paperboard coating machine and then push it into the cold pressing equipment. The pressing plate tightly glues the multi-layer paperboard together. Finally, the workers on the other side take out the multi-layer paperboard material and stack it on trolleys and other equipment.

[0004] During this process, because traditional equipment lacks the function of positioning cardboard of different sizes, workers may not stack the cardboard coated with glue neatly, causing the upper and lower layers of cardboard to be misaligned. Secondly, multi-layer cardboard composite structures, such as cat scratching boards, are heavy and bulky, and workers need to manually drag them out from the inside of the cold press and move them to a trolley on one side, which is very physically demanding after a long period of work.

[0005] Therefore, it is necessary to provide a new pressing device for paper products and paperboard processing to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a pressing device for paper product paperboard processing that can effectively position paperboard of multiple sizes, and at the same time facilitate workers to easily remove composite paperboard materials from under the pressure plate and transfer them to a trolley.

[0007] To solve the above-mentioned technical problems, the present invention provides a pressing device for paper products and paperboard processing, comprising: a pressing structure, the pressing structure including a support platform, a side support member fixedly connected to one side wall surface of the support platform, a side transmission structure provided on the top of the side support member, a boss and a lifting structure respectively provided at the front and rear ends of the support platform, and a positioning structure provided on the upper side of the boss.

[0008] The lifting structure includes a base plate and a top plate. The top plate is located above the base plate, and two vertical supports distributed front to back are fixedly connected between the base plate and the top plate. Movable parts are slidably connected to the surfaces of the vertical supports. Second sprockets are rotatably connected to the surfaces of the top plate and the base plate located on one side of the vertical supports. A second chain meshes between the two longitudinally distributed second sprockets. A double-headed motor is fixedly connected to the surface of the base plate located between the two vertical supports. The two output ends of the double-headed motor are fixedly connected to the two second sprockets respectively. The movable parts are fixedly connected to the second chain on the adjacent side. A lifting platform is fixedly connected to the side wall surface of the two movable parts relative to the second chain.

[0009] The positioning structure includes a positioning plate one, which is located on the upper side of the boss and has a double-ended screw rotatably connected to the side wall surface of the positioning plate one away from the lifting platform. Nuts are threaded to both the left and right sides of the surface of the double-ended screw. Positioning plates two are symmetrically slidably connected to the side wall surface of the positioning plate one relative to the double-ended screw. The two positioning plates two are respectively fixedly connected to the nuts on the adjacent side.

[0010] As a further embodiment of this utility model, the side transmission structure includes a first sprocket, two first sprockets are provided and are rotatably connected to the front and rear ends of the side support member respectively, a first chain is engaged between the two first sprockets, a drive motor is fixedly connected to the bottom surface of one end of the side support member, and the output end of the drive motor is fixedly connected to the first sprocket on the adjacent side.

[0011] Through the above technical solution, in order to facilitate workers to accurately position the cardboard, the device is specially designed with a positioning structure. Workers can adjust the distance between the two positioning plates in advance according to the required width of the cardboard to be stacked. After adjustment, the cardboard can be placed layer by layer. Since one end and the left and right sides of the cardboard are limited by the positioning plate and the two positioning plates, workers can quickly complete the positioning and neat stacking. The design is reasonable. Then, the drive motor can be started to drive the first sprocket on one side to rotate, which in turn causes the chain to drive the slider to move, and then drives the positioning plate to move horizontally and stably towards the support platform. This allows the cardboard group to move under the pressure plate by itself, which facilitates the pressing structure to press the multi-layer cardboard with glue. This structural design can quickly adjust the distance between the two positioning plates, thereby quickly positioning and stacking cardboard of different sizes.

[0012] As a further embodiment of this utility model, a guide rail is fixedly connected to the top surface of the side support member located on one side of the first chain, a slider is slidably connected to the surface of the guide rail, a connecting frame is fixedly connected between the slider and the front wall surface of the positioning plate, and the slider is fixedly connected to the first chain.

[0013] With the above technical solution, when the drive motor drives the first sprocket on one side to rotate, the slider fixedly connected to the first chain will slide along the guide rail.

[0014] As a further embodiment of this utility model, a through groove is provided on the surface of the positioning plate located on the lower side of the connecting frame, and a push plate is provided on the inner side of the through groove. An electric telescopic rod is fixedly connected to the surface of the positioning plate located on the lower side of the double-headed screw through a connecting plate, and the telescopic end of the electric telescopic rod is fixedly connected to the push plate.

[0015] With the above technical solution, after the multi-layer cardboard is pressed in the pressing structure, the side transmission structure can be activated to drive the positioning plate one to slide towards the lifting platform. At the same time, the electric telescopic rod two is opened, so that the push plate can pass through the inner side of the two positioning plates two and abut against the composite cardboard, so that it can push it onto the roller of the lifting platform, thus eliminating the need for manual operation by workers.

[0016] As a further embodiment of this utility model, a fixing member is provided on the upper side of the support platform. The fixing member is fixedly connected to the support platform through a connecting column. A motorized telescopic rod is symmetrically fixedly connected to the top of the fixing member. The telescopic end of the motorized telescopic rod passes through the fixing member and is fixedly connected to a pressure plate.

[0017] With the above technical solution, when the multi-layer cardboard comes to the underside of the pressure plate, the electric telescopic rod is activated to move the pressure plate down a set distance to press the multi-layer cardboard together, so that the multi-layer cardboard can be bonded more tightly with glue.

[0018] As a further embodiment of this utility model, one end of the top plate is fixedly connected to a fixing member, a number of evenly distributed rollers are rotatably connected inside the lifting platform, the boss is fixedly connected to the support platform, and brackets are fixedly connected to the bottom left and right edges of the support platform.

[0019] With the above technical solution, multi-layer cardboard composite structures, such as cat scratching boards, are heavy and bulky. Workers need to manually drag them out from the inside of the pressing structure and move them to a trolley on one side. This is very physically demanding after a long period of work. This device is specially designed to work with the pressing structure and has a lifting function. Workers can fix the trolley in advance on one side of the lifting platform. Then, the multi-layer composite cardboard under the pressing plate can be automatically pushed onto the roller by the side transmission structure and the push plate. Then, the worker starts the double-head motor to drive the second sprocket to rotate. The second chain then drives the moving parts on one side and the lifting platform to change the height, so that the lifting platform can be smoothly aligned with the height of the trolley platform. After that, the worker only needs to push the composite cardboard horizontally to complete the transfer work. There is no need to manually lift and move it, making the operation much more labor-saving.

[0020] As a further embodiment of this utility model, a control module is fixedly connected to the top edge of the fixing member, and the dual-head motor, drive motor, electric telescopic rod one, and electric telescopic rod two are all electrically connected to the control module.

[0021] The above technical solution, through the setting of a control module, enables workers to more easily and effectively complete the pressing operation of multi-layer cardboard.

[0022] Compared with related technologies, the pressing device for paperboard processing provided by this utility model has the following advantages:

[0023] 1. In this utility model, in order to facilitate workers to accurately position the cardboard, the device is specially designed with a positioning structure. Workers can adjust the distance between the two positioning plates in advance according to the required width of the cardboard to be stacked. After adjustment, the cardboard can be placed layer by layer. Since one end and the left and right sides of the cardboard are limited by the positioning plate and the two positioning plates, workers can quickly complete the positioning and neat stacking. The design is reasonable. Then, the drive motor can be started to drive the first sprocket on one side to rotate, which in turn drives the chain to move the slider, and then drives the positioning plate to move horizontally and stably towards the support table, so that the cardboard group can move under the pressure plate by itself, thereby facilitating the pressing structure to press the multi-layer cardboard with glue. This structural design can quickly adjust the distance between the two positioning plates, thereby quickly positioning and stacking cardboard of different sizes.

[0024] 2. In this utility model, the multi-layer cardboard composite structure, such as the cat scratching board, is heavy and bulky.

This device is specially designed to cooperate with the pressing structure and has a lifting function. Workers can fix the trolley in advance on one side of the lifting platform. Then, the multi-layer composite cardboard under the pressing plate can be automatically pushed onto the roller by the cooperation of the side transmission structure and the push plate. Then, the worker starts the double-head motor to drive the second sprocket to rotate. Then, the second chain drives the moving part on one side and the lifting platform to change the height, so that the lifting platform can be smoothly connected to the height of the trolley platform. After that, the worker only needs to push the composite cardboard horizontally to complete the transfer work. There is no need to manually lift and move it, making the operation more labor-saving.

The pressing device for processing paper products and paperboard includes:

[0033] The pressing structure 1 includes a support platform 7. A side support member 11 is fixedly connected to one side wall surface of the support platform 7.

A second sprocket 22 is rotatably connected to the surface of the top plate and the base plate located on one side of the vertical support 20. A second chain 21 meshes between the two longitudinally distributed second sprockets 22. A double-head motor 23 is fixedly connected to the surface of the base plate located between the two vertical supports 20. The two output ends of the double-head motor 23 are fixedly connected to the two second sprockets 22 respectively. The movable part 19 is fixedly connected to the second chain 21 on the adjacent side. A lifting platform 24 is fixedly connected to the side wall surface of the two movable parts 19 relative to the second chain 21.

[0035] The positioning structure 5 includes a positioning plate 16, which is located on the upper side of the boss 17 and is rotatably connected to a double-ended screw 27 on the side wall surface of the positioning plate 16 away from the lifting platform 24. Nuts are threaded to both sides of the surface of the double-ended screw 27. Positioning plates 29 are symmetrically slidably connected to the positioning plate 16 on the left and right sides of the side wall surface of the double-ended screw 27. The two positioning plates 29 are fixedly connected to the nuts on the adjacent sides respectively.

[0036] like Figure 1-4 As shown, the side transmission structure 4 includes a first sprocket 14. There are two first sprockets 14, which are rotatably connected to the front and rear ends of the side support member 11 respectively. A first chain 13 meshes between the two first sprockets 14. A drive motor 15 is fixedly connected to the bottom surface of one end of the side support member 11. The output end of the drive motor 15 is fixedly connected to the first sprocket 14 on the adjacent side.

[0037] To facilitate precise positioning of cardboard by workers, the device is specially designed with a positioning structure 5. Workers can adjust the distance between the two positioning plates 29 in advance according to the required width of the cardboard to be stacked. After adjustment, the cardboard can be placed layer by layer. Since one end and the left and right sides of the cardboard are limited by the positioning plate 16 and the two positioning plates 29, workers can quickly complete the positioning and neat stacking. The design is reasonable. Then, the drive motor 15 can be started to drive the first sprocket 14 on one side to rotate, which in turn causes the chain to drive the slider 28 to move, and then drives the positioning plate 16 to move horizontally and stably towards the support table 7, so that the cardboard group can move under the pressure plate 10 by itself, thereby facilitating the pressing structure 1 to press the multi-layer cardboard with glue. This structural design can quickly adjust the distance between the two positioning plates 29, thereby quickly positioning and stacking cardboard of different sizes.

[0038] like Figure 1-4As shown, a guide rail 12 is fixedly connected to the top surface of the side support member 11 located on one side of the first chain 13. A slider 28 is slidably connected to the surface of the guide rail 12. A connecting frame is fixedly connected between the slider 28 and the front wall surface of the positioning plate 16. The slider 28 is fixedly connected to the first chain 13.

[0039] When the drive motor 15 drives the first sprocket 14 on one side to rotate, the slider 28, which is fixedly connected to the first chain 13, will slide along the guide rail 12.

[0040] like Figure 1-4 As shown, a through groove is provided on the surface of the positioning plate 16 located on the lower side of the connecting frame, and a push plate 26 is provided on the inner side of the through groove. An electric telescopic rod 18 is fixedly connected to the surface of the positioning plate 16 located on the lower side of the double-headed screw 27 through a connecting plate. The telescopic end of the electric telescopic rod 18 is fixedly connected to the push plate 26.

[0041] After the multi-layer cardboard is pressed together in the pressing structure 1, the side transmission structure 4 can be activated to drive the positioning plate 16 to slide towards the lifting platform 24. At the same time, the electric telescopic rod 18 is opened, so that the push plate 26 can pass through the inside of the two positioning plates 29 and abut against the composite cardboard, so that it can push it onto the roller 25 of the lifting platform 24, thus eliminating the need for manual operation by workers.

[0042] like Figure 1-4 As shown, a fixing member 8 is provided on the upper side of the support platform 7. The fixing member 8 is fixedly connected to the support platform 7 through a connecting column. An electric telescopic rod 9 is symmetrically fixedly connected to the top of the fixing member 8. The telescopic end of the electric telescopic rod 9 passes through the fixing member 8 and is fixedly connected to a pressure plate 10.

[0043] When the multi-layer cardboard comes to the underside of the pressure plate 10, the electric telescopic rod 9 is activated to move the pressure plate 10 down a set distance to press the multi-layer cardboard together, so that the multi-layer cardboard can be bonded more tightly with glue.

[0044] like Figure 1-4 As shown, one end of the top plate is fixedly connected to the fixing member 8, and several evenly distributed rollers 25 are rotatably connected inside the lifting platform 24. The boss 17 is fixedly connected to the support platform 7, and brackets 2 are fixedly connected to the bottom left and right edges of the support platform 7.

[0045] Multi-layer cardboard composite structures, such as cat scratching boards, are heavy and bulky. Workers need to manually drag them out from the inside of the pressing structure 1 and move them to a trolley on one side. This is very physically demanding after a long time. This device is specially designed to work with the pressing structure and has a lifting function. Workers can fix the trolley in advance on one side of the lifting platform 24. Then, the multi-layer composite cardboard under the pressing plate 10 can be automatically pushed onto the roller 25 by the cooperation of the side transmission structure 4 and the push plate 26. Then, the worker starts the double-head motor 23 to drive the second sprocket 22 to rotate. Then, the second chain 21 drives the moving part 19 on one side and the lifting platform 24 to change the height. This allows the lifting platform 24 to be smoothly aligned with the height of the trolley platform. After that, the worker only needs to push the composite cardboard horizontally to complete the transfer work. There is no need to manually lift and move it, making the operation much more labor-saving.

[0046] like Figure 1-4 As shown, a control module 3 is fixedly connected to the top edge of the fastener 8. The dual-head motor 23, drive motor 15, electric telescopic rod 1 9, and electric telescopic rod 2 18 are all electrically connected to the control module 3.

[0047] By setting up control module 3, workers can more easily and effectively complete the pressing operation of multi-layer cardboard.

[0048] The working principle of the pressing device for paper product and paperboard processing provided by this utility model is as follows:

[0049] First step: To facilitate workers' precise positioning of cardboard, the device is specially designed with a positioning structure 5. Workers can adjust the distance between the two positioning plates 29 in advance according to the required width of the cardboard to be stacked. After adjustment, the cardboard can be placed layer by layer. Since one end and the left and right sides of the cardboard are limited by the positioning plate 16 and the two positioning plates 29, workers can quickly complete the positioning and neat stacking. The design is reasonable. Then, the drive motor 15 can be started to drive the first sprocket 14 on one side to rotate, which in turn drives the chain to move the slider 28, and then drives the positioning plate 16 to move horizontally and stably towards the support table 7, so that the cardboard group can move under the pressure plate 10 by itself, which facilitates the pressing structure 1 to press the multi-layer cardboard with glue. This structure design can quickly adjust the distance between the two positioning plates 29, so as to quickly position and stack cardboard of different sizes.

[0050] The second step involves multi-layered cardboard composite structures, such as cat scratching boards, which are heavy and bulky. Workers need to manually drag them out from the inside of the pressing structure 1 and move them to a trolley on one side. This is very physically demanding after a long period of work. This device is specifically designed to work with the pressing structure and has a lifting function. Workers can fix the trolley to one side of the lifting platform 24 in advance. Then, by using the side transmission structure 4 and the push plate 26, the multi-layered composite cardboard under the pressing plate 10 can be automatically pushed onto the roller 25. Next, the worker starts the double-headed motor 23 to drive the second sprocket 22 to rotate. Then, the second chain 21 drives the moving part 19 on one side and the lifting platform 24 to change the height, so that the lifting platform 24 can be smoothly aligned with the height of the trolley platform. After that, the worker only needs to push the composite cardboard horizontally to complete the transfer work. There is no need to manually lift and move it, making the operation much easier.
