Abstract
Description
Technical Field
[0001] The invention 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 a kind of recycled waste paper. It 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 the shape of paper, and then carry out cutting, drying and other processes, 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 the grey cardboard, since multiple winding rollers are in a fixed state, when the grey cardboard starts to be wound, the fixed winding rollers may not fit tightly against the inner wall of the cardboard when winding the cardboard, causing the cardboard to become loose during rotation and creases to appear on the cardboard as it is wound. When the number of winding turns increases, the inner wall of the cardboard may be torn and broken if the rotation speed is not adjusted in time.
[0005] Therefore, the present invention provides a winding device for processing grey paperboard to solve the above problems. Summary of the invention
[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 to 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 with a 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 invention 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 close to the tensioning assembly.
[0010] A further improvement of the technical solution of the present invention 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 at one end 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 with 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 invention 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, 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 a 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 invention is that: one of the outer walls of the lifting frame 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: a fixing frame is fixedly connected to the top of the support plate located on one side of the lifting frame, and a rotating roller is rotatably connected to the inner wall of the fixing frame.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Through the tensioning assembly inside the winding equipment, the tensioning disk can timely adjust the supporting force of the cardboard in the early stage of cardboard winding, so that it can better fit 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 winding, it is very easy to loosen the winding, and as the winding thickness increases, it is also easy to cause creases on 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 can be lifted or lowered in time to change the angle with the fixed roller, thereby adjusting the tension of the cardboard to avoid the cardboard always being at the same height during the winding process. The tension of the cardboard cannot be changed with the increase of the winding thickness, resulting in cardboard breakage or tearing. BRIEF DESCRIPTION OF THE DRAWINGS

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 specified.
[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, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.
[0027] Reference Figure 1-Figure 6 , the present invention provides three technical solutions:
[0028] Embodiment 1:
[0029] A winding device for grey paperboard processing 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 rotatably connected to a rotating seat 202, the inner wall of the rotating seat 202 is symmetrically and detachably connected to a rotating disk 203, a threaded rod 204 is fixedly connected to the center of the inner wall of the rotating disk 203, and a plurality of tensioning disks 205 are threadedly connected to the outer wall of the threaded rod 204, and a plurality of sliding limit grooves 206 are annularly opened on the outer wall of the rotating disk 203, and a tensioning plate 207 is longitudinally slidably connected to the inner wall of the sliding limit groove 206, and the tensioning plate 207 is in a The tensioning disc 205 is inclined, and a slide groove 208 is provided in an annular outer wall thereof. The inclined end of the tensioning plate 207 slides in the slide groove 208. The tensioning assembly 2 also includes a rotating rod 209 rotatably connected to 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 winding device is working, the gray cardboard is first passed 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. A height difference is formed by the heights of the two, which can provide sufficient tension for the gray cardboard to avoid slack during the winding process, which makes the winding chaotic. Then the gray cardboard is wrapped around 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 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 rolling marks on the cardboard, reducing production efficiency and wasting materials.
[0032] Embodiment 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 a driven wheel 302 is fixedly sleeved on the end of the driving shaft 301 away from the rotating seat 202, 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 on the end away from the driven wheel 302, and a driving motor 305 is fixedly connected to the top of the support plate 1 on one side of the driving wheel 304, 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 rolling 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, the tensioning disk 205 can be driven to rotate when it rotates, and then the gray cardboard on its outer wall is rolled up through the tensioning plate 207, which does not conflict with the work of the tensioning component 2. When the rolling is completed, since the rotating seat 202 and the rotating disk 203 are detachably connected, the rotating disk 203 can be removed to unload the rolled gray cardboard.
[0036] Embodiment three:
[0037] Based on the second embodiment:
[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, and 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 side wall of 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 is meshed with the driven bevel gear 410 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 paperboard on the outer wall of the tensioning plate 207 increases, its surface area also gradually increases. The driving bevel gear 409 is driven to rotate by rotating the rotating rod 408, and then the reciprocating screw rod 406 is driven to rotate by the meshing 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 be longitudinally lifted and lowered. The tension of the gray paperboard passing through the surfaces of the two can be adjusted by adjusting the height difference between the lifting platform 405 and the rotating roller 102, thereby avoiding the tight state of the gray paperboard caused by the increase in winding thickness, improving production efficiency and reducing the loss of gray paperboard.
