Description

Technical Field

[0001] The utility model relates to the technical field of paperboard rolling, in particular to a rolling device for processing grey paperboard. Background Art

[0002] Gray cardboard is made from recycled waste paper and is divided into single gray, double gray, and full gray. It is an environmentally friendly packaging material. Its main uses include packaging boxes, advertising boards, folders, photo frame backs, luggage, hardcover books, storage boxes, samples, lining boards, partitions, etc.

[0003] In the existing production and processing of gray cardboard, a large amount of paper processing is inseparable from winding equipment. The winding equipment can quickly roll and pack the gray cardboard processed into paper shape, and then carry out processes such as cutting and drying, and finally transport it to complete the production process. The winding equipment can replace the previous manual winding process, which can improve efficiency and avoid the occurrence of safety accidents.

[0004] However, in the current production and winding process of gray cardboard, since multiple winding rollers are in a fixed state, when the gray cardboard starts to be wound, the fixed winding rollers are very likely to not fit tightly against the inner wall of the cardboard when winding the cardboard. When rotating, the cardboard will become loose and creases will easily appear on the cardboard as it is wound. When the number of winding turns increases, if the rotation speed is not adjusted in time, the inner wall of the cardboard may be torn and broken.

[0005] Therefore, the utility model provides a winding device for gray paperboard processing to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention provides a winding device for processing grey paperboard, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A winding device for processing grey paperboard comprises a support plate, to which a tensioning assembly for improving winding efficiency is fixedly connected;

[0008] The tensioning assembly includes a support frame fixedly connected to the top of the support plate, the inner wall of the support frame is symmetrically rotatably connected to a rotating seat, the inner wall of the rotating seat is symmetrically and detachably connected to a rotating disk, a threaded rod is fixedly connected at the center of the inner wall of the rotating disk, the outer wall of the threaded rod is threadedly connected to multiple tensioning disks, the outer wall of the rotating disk is annularly provided with multiple sliding limit grooves, the inner wall of the sliding limit groove is longitudinally slidably connected to the tensioning plate, the tensioning plate is inclined, the outer wall of the tensioning disk is annularly provided with a sliding groove, and the inclined end of the tensioning plate slides in the sliding groove.

[0009] A further improvement of the technical solution of the present utility model is that: the tensioning assembly also includes a rotating rod rotatably connected inside one of the support frames, one end of the rotating rod is connected to the threaded rod, and the end of the rotating rod away from the support frame is fixedly connected to a rotating handle, a driving assembly is provided on the support plate on one side of the tensioning assembly, and a lifting assembly is provided on the support plate on the side close to the tensioning assembly.

[0010] A further improvement of the technical solution of the present utility model is that: the driving assembly includes a driving shaft rotatably connected to the inside of the support frame, one end of the driving shaft is fixedly connected to the rotating seat, the end of the driving shaft away from the rotating seat is fixedly sleeved with a driven wheel, the outer wall of the driven wheel is transmission-connected with a synchronous belt, and the inner wall of the synchronous belt is transmission-connected with a driving wheel away from the driven wheel, the top end of the support plate is located on one side of the driving wheel and is fixedly connected to a driving motor, and the output end of the driving motor is fixedly sleeved with the driving wheel.

[0011] A further improvement of the technical solution of the present utility model is that: the lifting assembly includes a lifting frame symmetrically fixedly connected to the top of the support plate, and a sliding groove is opened in the middle of the lifting frame, and a lifting seat is slidably connected to the inner wall of the sliding groove, one end of the lifting seat is fixedly connected to a lifting roller, and one end of the lifting roller passes through the lifting seat and is fixedly connected to the lifting platform, and a reciprocating screw is threadedly connected to the middle of the lifting platform.

[0012] A further improvement of the technical solution of the present utility model is that: the outer wall of one of the lifting frames is fixedly connected to a lifting box, and the side wall of the lifting box is rotatably connected to a rotating rod, and one end of the rotating rod located in the lifting box is fixedly connected to a driving bevel gear, and the lower bottom end of the reciprocating screw is fixedly connected to a driven bevel gear, and the driving bevel gear and the driven bevel gear are meshed for transmission.

[0013] A further improvement of the technical solution of the present invention is that: the top end of the support plate is fixedly connected to a fixing frame on one side of the lifting frame, and the inner wall of the fixing frame is rotatably connected to a rotating roller.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The tensioning assembly inside the winding equipment can timely adjust the supporting force of the tensioning disk on the cardboard in the early stage of cardboard winding, so that the cardboard can be better fitted with the inner wall of the cardboard in the circumferential direction. Since the cardboard material itself has a certain strength, if the inside is not tight during the early stage of winding, it is very easy to loosen the winding, and as the winding thickness increases, it is also easy to cause creases in the cardboard.

[0016] 2. The height between the lifting roller and the fixed roller can be adjusted in time through the lifting component. When the winding thickness increases, the lifting roller is raised or lowered in time to change the angle with the fixed roller, thereby adjusting the tension of the cardboard. This avoids the cardboard always being at the same height during the winding process, and the cardboard tension cannot be changed as the winding thickness increases, resulting in cardboard breakage or tearing.

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0025] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0026] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0027] Reference Figures 1-6 , this utility model provides three technical solutions:

[0028] Example 1:

[0029] A winding device for processing grey paperboard comprises a support plate 1, to which a tensioning assembly 2 for improving winding efficiency is fixedly connected;

[0030] The tensioning assembly 2 includes a support frame 201 fixedly connected to the top of the support plate 1, the inner wall of the support frame 201 is symmetrically connected to the rotating seat 202, the inner wall of the rotating seat 202 is symmetrically and detachably connected to the rotating disk 203, a threaded rod 204 is fixedly connected to the center of the inner wall of the rotating disk 203, the outer wall of the threaded rod 204 is threadedly connected to multiple tensioning disks 205, the outer wall of the rotating disk 203 is annularly provided with multiple sliding limit grooves 206, the inner wall of the sliding limit groove 206 is longitudinally connected to the tensioning plate 207, and the tensioning plate 207 is arranged in a straight line. The outer wall of the tensioning disk 205 is provided with a sliding groove 208 in an annular shape, and the inclined end of the tensioning plate 207 slides in the sliding groove 208. The tensioning assembly 2 also includes a rotating rod 209 that is rotatably connected to the inside of one of the support frames 201. One end of the rotating rod 209 is connected to the threaded rod 204, and the end of the rotating rod 209 away from the support frame 201 is fixedly connected to a rotating handle 210. A driving assembly 3 is provided on the support plate 1 on one side of the tensioning assembly 2, and a lifting assembly 4 is provided on the support plate 1 on the side close to the tensioning assembly 2.

[0031] Specifically, the support plate 1 can provide sufficient stability for the winding device to avoid instability during high-speed operation. When the gray cardboard is in winding operation, it first passes through the upper surface of the rotating roller 102 on the inner wall of the fixed frame 101, and then passes through the outer surface of the lifting roller 404. The height difference between the two forms a height difference, which can provide sufficient tension for the gray cardboard to avoid slack during the winding process, causing winding disorder. Then the gray cardboard is wound on the outer wall of the tensioning plate 207 of the tensioning assembly 2, and the threaded rod 204 is driven to rotate by rotating the rotating handle 210, thereby driving the tensioning disk 205 threadedly connected to its outer wall to move in one direction. Through the slide groove 208 on the outer wall of the tensioning disk 205 and the tensioning plate 207 sliding inside it, it will continuously output tensioning force to the inner wall of the gray cardboard through outward movement, so that the inner wall of the gray cardboard is always in a taut state during the rotation of the gray cardboard, avoiding a loose state during winding, causing roll marks on the cardboard, reducing production efficiency and wasting materials.

[0032] Example 2:

[0033] Based on Example 1:

[0034] The driving assembly 3 includes a driving shaft 301 rotatably connected to the inside of the support frame 201, one end of the driving shaft 301 is fixedly connected to the rotating seat 202, and the end of the driving shaft 301 away from the rotating seat 202 is fixedly sleeved with a driven wheel 302, the outer wall of the driven wheel 302 is transmission-connected with a synchronous belt 303, and the inner wall of the synchronous belt 303 is transmission-connected with a driving wheel 304 away from the driven wheel 302. The top end of the support plate 1 is located on one side of the driving wheel 304 and is fixedly connected to a driving motor 305, and the output end of the driving motor 305 is fixedly sleeved with the driving wheel 304.

[0035] Specifically, by operating the driving motor 305 inside the driving component 3, the problem of low efficiency of manual cardboard winding can be avoided. The driving motor 305 drives the active wheel 304 connected to the output end to rotate, and then drives the driven wheel 302 to rotate through the synchronous belt 303. Since the driven wheel 302 is connected to the driving shaft 301, and the other end of the driving shaft 301 is connected to the rotating seat 202, it can drive the tensioning disk 205 to rotate when it rotates, and then the gray cardboard on its outer wall is wound up through the tensioning plate 207, which does not conflict with the work of the tensioning component 2. When the winding is completed, since the rotating seat 202 and the rotating disk 203 are detachably connected, the rotating disk 203 can be removed and the rolled gray cardboard can be unloaded.

[0036] Example 3:

[0037] Based on Example 2:

[0038] The lifting assembly 4 includes a lifting frame 401 symmetrically fixedly connected to the top of the support plate 1, and a sliding groove 402 is opened in the middle of the lifting frame 401, and a lifting seat 403 is slidably connected to the inner wall of the sliding groove 402, one end of the lifting seat 403 is fixedly connected to a lifting roller 404, and one end of the lifting roller 404 passes through the lifting seat 403 and is fixedly connected to a lifting platform 405, and a reciprocating screw rod 406 is threadedly connected to the middle of the lifting platform 405, one of the lifting frames 401 is fixedly connected to a lifting box 407 on the outer wall, and the lifting box 407 is rotatably connected to a rotating rod 408, and one end of the rotating rod 408 located in the lifting box 407 is fixedly connected to a driving bevel gear 409, and the lower bottom end of the reciprocating screw rod 406 is fixedly connected to a driven bevel gear 410, and the driving bevel gear 409 and the driven bevel gear 410 are meshed for transmission.

[0039] Specifically, the lifting frame 401 in the lifting assembly 4 can provide it with sufficient lifting space. When the winding thickness of the gray cardboard on the outer wall of the tensioning plate 207 increases, its surface area also gradually increases. By rotating the rotating rod 408, the active bevel gear 409 is driven to rotate, and then the reciprocating screw rod 406 is driven to rotate through the engaged driven bevel gear 410, so that the lifting platform 405 on its outer wall is longitudinally lifted and lowered. The lifting and lowering of the lifting platform 405 can drive the lifting seat 403 to slide longitudinally inside the sliding groove 402, and drive the lifting roller 404 to move longitudinally. By adjusting the height difference between it and the rotating roller 102, the tension of the gray cardboard passing through the two surfaces is adjusted, thereby avoiding the tension of the gray cardboard caused by the increase in winding thickness, improving production efficiency and reducing the loss of the gray cardboard.
