Description

Technical Field

[0001] This utility model relates to the field of roll material processing, specifically a slitting and rewinding device. Background Technology

[0002] A rewinding device is used to wind rolls of material into regular coils, while a slitting machine is used to cut materials into segments of different widths. Existing integrated slitting and rewinding mechanisms have drawbacks: for example, the cutting device is not adjustable, making it inconvenient to cut materials of different thicknesses. Furthermore, the material is not compressed during the winding process, which can easily result in insufficient tension in the rolled material.

[0003] For example, Chinese patent CN105347083B discloses a slitting and rewinding machine, including a left wall panel and a right wall panel. An upper roller, a lower roller, a cutting device, and an unwinding roller are provided between the left and right wall panels. A take-up chuck is also provided above the upper roller. The machine is characterized by a swinging device located between the left and right wall panels, positioned above the upper roller, with the take-up chuck mounted on the swinging device. The swinging device includes a swing shaft, limiting devices at both ends of the swing shaft, and a motor at one end of the swing shaft. The take-up chuck is mounted on the swing shaft via a swing arm. Both ends of the swing shaft are mounted on the left and right wall panels via the limiting devices. The motor is connected to the limiting device at one end of the swing shaft via an elliptical wheel. The cutting device of the aforementioned slitting and rewinding machine is not easily adjustable, making it unsuitable for cutting materials of different thicknesses. At the same time, the lack of a pressing mechanism to compress the coiled material can easily lead to a lack of tension in the wound material.

[0004] Therefore, it is necessary to provide a slitting and rewinding device. Utility Model Content

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, the slitting and rewinding device provided in this application includes an unwinding mechanism 1 and a rewinding and slitting mechanism 2 located on one side of the unwinding mechanism 1. The rewinding and slitting mechanism 2 includes a first frame 21, a winding assembly 22 mounted on the first frame 21, several slitting assemblies 23 mounted below the winding assembly 22, a pushing assembly 24 mounted below the winding assembly 22, and a pressing assembly 25 mounted above the winding assembly 22. The slitting assembly 23 includes a lower blade 231 mounted on the first frame 21, a first linear guide rail 232 mounted vertically on the first frame 21, a lifting seat 233 slidably mounted on the first linear guide rail 232, an upper blade 234 mounted on the lifting seat 233, and a first hydraulic cylinder 235 mounted on the first frame 21 for driving the lifting seat 233 to rise and fall.

[0021] In actual use, the end of the roll material 100 to be slit is pulled to the winding assembly 22 for fixation, and then the winding assembly 22 winds it up. During the winding process, the material is slit by the upper blade 234. During slitting, the material is supported and carried by the lower blade 231. During winding, the material in the winding assembly 22 is rolled and pressed by the pressure assembly 25. When it is necessary to adjust the height of the upper blade 234, the lifting seat 233 is raised and lowered by the first hydraulic cylinder 235 to achieve the most suitable paper cutting height.

[0022] In the above design, the slitting machine and the winding machine are integrated, which can both slitting and winding the material, and at the same time, the pressure winding assembly 25 can be used to ensure that the material wound by the winding assembly 22 has tension.

[0023] Specifically: such as Figure 2 As shown, the take-up assembly 22 includes a take-up roller 223, a second linear guide rail 221 vertically mounted on a first frame 21, a lifting frame 222 mounted on the second linear guide rail 221, a tensioning shaft mounted on the lifting frame 222 for tensioning the take-up roller 223, a first bottom roller 224 and a second bottom roller 225 mounted on the first frame 21 and located below the take-up roller 223, a first motor for driving the first bottom roller 224 to rotate, and a second motor for driving the second bottom roller 225 to rotate. The first bottom roller 224 and the second bottom roller 225 are symmetrical about the take-up roller 223 axis. A support area is formed between the first bottom roller 224 and the second bottom roller 225.

[0024] In actual use, the No. 1 bottom roller 224 and the No. 2 bottom roller 225, driven by the No. 1 motor and the No. 2 motor respectively, pull the coiled material 100 on the take-up roller 223, thereby driving the take-up roller 223 to wind up the material. During the winding process, as the coiled material 100 becomes more abundant and thicker, the take-up roller 223, under the action of contact between the No. 1 bottom roller 224 and the No. 2 bottom roller 225 and the coiled material 100, drives the lifting frame 222 to rise along the No. 2 linear guide rail 221. After the coiled material 100 is finished, the take-up roller 223 is removed from the tensioning shaft, so that the take-up roller 223 is placed in the material support area formed by the No. 1 bottom roller 224 and the No. 2 bottom roller 225.

[0025] In the above design, the structural design and specific implementation of the winding assembly 22 can effectively support and drive the material in the winding state, and at the same time support the wound material 100 after winding.

[0026] Specifically: such as Figure 2 and Figure 4 As shown, the pushing assembly 24 includes a second rotating frame 241 mounted on the first frame 21, a pushing roller 242 mounted at one end of the second rotating frame 241, and a second hydraulic cylinder 243 mounted on the first frame 21 for driving the second rotating frame 241 to rotate.

[0027] In actual use, after the winding assembly 22 finishes winding the roll 100, the roll 100 is placed in the support area formed by the first bottom roller 224 and the second bottom roller 225. Then, the second hydraulic cylinder 243 drives the second rotating frame 241 to rotate, so that the second rotating frame 241 drives the pusher roller 242 to rotate synchronously and push the roll 100 in the support area, so that the roll 100 is removed from the support area.

[0028] In the above design, the structural design and specific implementation of the pusher component 24 can push the roll 100 that has detached from the tensioning shaft, so that the roll 100 in the support area can automatically detach from the slitting and rewinding integrated device of this application.

[0029] Specifically: such as Figure 2 As shown, the coiling assembly 25 includes a swing arm 251 hinged to a first frame 21, a coiling roller 252 disposed at one end of the swing arm 251, and a third hydraulic cylinder 253 disposed on the first frame 21 for driving the swing arm 251 to rotate. It should be noted that the third hydraulic cylinder 253 controls the hydraulic pressure by outputting current through a hydraulic proportional valve, ensuring that the driving force of the third hydraulic cylinder 253 on the swing arm 251 achieves a certain ratio between the lifting height of the coiling roller 252 and the lifting height of the take-up roller 223, ensuring that the coiling roller 252 always presses the outermost layer of material on the take-up roller 223.

[0030] In actual use, when the take-up roller 223 is winding the material, the swing arm 251 is driven by the No. 3 hydraulic cylinder 253 to swing and lift the pressure roller 252. This allows the pressure roller 252 to adapt to the height of the rise along the No. 2 linear guide rail 221 as the coiled material 100 becomes thicker, thus achieving the pressing of the outermost layer of the coiled material 100 on the take-up roller 223.

[0031] In the above design, the structural design and specific implementation of the compression assembly 25 can compress the material during the winding process, prevent the roll 100 from loosening during the winding process, and ensure the tension of the roll 100 on the winding roller 223.

[0032] Specifically: such as Figure 2 and Figure 3 As shown, the upper blade 234 includes a mounting base 2341 fixedly connected to the lifting seat 233, a third linear guide rail 2342 extending axially along the winding assembly 22 and disposed on the mounting base 2341, a slide block 2343 slidably disposed on the third linear guide rail 2342, a guide rail locking mechanism 2344 disposed on the slide block 2343 for locking the slide block 2343 and the third linear guide rail 2342, and a cutter 2345 disposed on the slide block 2343. It should be noted that the guide rail locking mechanism 2344 is an existing structure and can be a guide rail clamp.

[0033] In actual use, when it is necessary to change the width of the material to be cut, loosen the guide rail locking mechanism 2344, and then slide the slide block 2343 along the third linear guide rail 2342, so that the cutter 2345 moves to the predetermined horizontal position. Then tighten the guide rail locking mechanism 2344.

[0034] In the above design, the structural design and specific implementation of the upper blade 234 facilitate the adjustment of materials with different cutting widths and cutting positions.

[0035] Specifically: such as Figure 2 As shown, several guide rollers 26 are also provided on the first frame 21.

[0036] In the above design, the guide roller 26 is used to tension and guide the material before slitting.

[0037] Specifically: such as Figure 1 As shown, the unwinding mechanism 1 includes a second frame 11 and an unwinding roller 12 disposed on the second frame 11.

[0038] In the above design, the material is unwound by the unwinding roller 12 to ensure that raw materials are supplied to the slitting assembly 23 and the winding assembly 22.

[0039] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
