[0002] In the modern papermaking industry and related paper processing industries, paper rewinders are an indispensable and important piece of equipment. Rewinders are mainly used to rewind the raw paper rolls produced by the papermaking machine. They can also perform a series of operations such as slitting, removing burrs, and inspecting paper quality, ultimately producing finished paper rolls that meet the needs of different users.

[0003] In traditional paper rewinding processes, most rewinding machines are designed with a fixed width. This means that when different widths of paper need to be produced, the entire rewinding equipment often needs to be replaced, which undoubtedly increases production costs and time significantly.

[0004] On the one hand, frequent equipment replacements not only require a significant investment in purchasing new rewinding machines, but also lead to resource waste due to the idleness and disposal of old equipment. On the other hand, complex adjustments to fixed-width rewinding machines not only require a large amount of time and effort from professional technicians, but improper adjustments may also affect the normal operation of the equipment and the rewinding quality of the paper.

[0005] Furthermore, the limitations of fixed-width rewinders are even more pronounced in small-batch, multi-variety paper production. The inability to adjust the rewinding width makes production impossible, hindering the ability to meet market demands for rapid response and diversified products. Utility Model Content

[0030] The following will be further described in combination with the drawings and specific embodiments:

[0031] In order to be able to adjust the width of the rewinding machine according to the demand, adapt to the production demand of different width paper, the embodiment provides a new rewinding machine. The rewinding machine is improved on the basis of the existing rewinding machine, therefore, before introducing the specific improvement point, the existing rewinding machine needs to be simply introduced.

[0032] As Figure 1As shown, the existing rewinding machine includes unwinding mechanism, paper feeding mechanism, rewinding mechanism, cutting mechanism, control system, etc. The unwinding mechanism includes a paper roll frame, an unwinding tension control system, etc. The paper roll frame is used to place the original paper roll to be rewound, and usually has an adjustable support structure to accommodate paper rolls of different widths and diameters. The unwinding tension control system detects the tension of the paper in real time through sensors and automatically adjusts the unwinding speed according to the set value to ensure that the paper maintains a constant tension during unwinding. The paper feeding mechanism includes a paper feeding roller set, a tension adjusting device, etc. The paper feeding roller set is composed of multiple paper feeding rollers, which convey the paper from the unwinding mechanism to the rewinding mechanism through the rotation of the rollers. In addition to unwinding tension control, the tension adjusting device further adjusts the tension of the paper during the paper feeding process. The tension adjusting device can use air cylinders, springs or electric actuators, etc. to accurately adjust according to the characteristics of the paper and the rewinding requirements. The rewinding mechanism includes a rewinding shaft, a driving device, etc. The driving device provides power to the rewinding shaft so that it can rotate at a set speed and direction. The driving device generally uses a combination of motors and reducers, which transmits power to the rewinding shaft through a transmission system such as a belt, chain or gear. The cutting mechanism includes a cutter and a cutter driving system. The control system includes an electrical control cabinet, an operation panel, etc. The electrical control cabinet integrates various electrical components and controllers such as PLC (Programmable Logic Controller), frequency converter, relay, etc. to control the coordinated operation of various parts of the rewinding machine.

[0033] In the improvement of the above-mentioned rewinding machine, the components across the entire rewinding machine such as the frame, the roller body and the rewinding shaft are improved and processed, that is, the frame, the roller body and the rewinding shaft are adjusted and set. For example, the frame is set as two spliced parts, the most common splicing method is to insert one part into another part, when the state of the frame needs to be changed, the relative movement of the two spliced parts is controlled to achieve the adjustment of the size of the frame.

[0034] As shown in Figure 2 , when the frame is set as an adjustable splicing structure, a bottom steel 2 is arranged at the bottom of the frame, and a lifting mechanism 5 can be installed at the bottom steel 2. The bottom steel 2 is lifted off the ground by the operation of the lifting mechanism 5, and then the frame is moved under the action of external force, so that the size of the frame can be adjusted.

[0035] As shown in Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, in order to facilitate the lifting of the bottom steel 2, the lifting mechanism 5 comprises a crossbeam 53 and a wheel body 51, a connecting frame 52 is arranged on the top of the wheel body 51, a plum blossom column 521 is fixedly arranged above the connecting frame 52, a plum blossom hole 531 is arranged at the end of the crossbeam 53, the plum blossom column 521 is inserted into the plum blossom hole 531, and thus the wheel body 51 and the crossbeam 53 are connected by disassembly under the cooperation of the plum blossom column 521 and the plum blossom hole 531, so as to be quickly assembled during use. In addition, a lifting plate 535 is arranged above the crossbeam 53, the lifting plate 535 is arranged in a cross structure, and a threaded hole 534 is arranged at the end of the lifting plate 535. At the same time, a threaded column 532 is arranged on the crossbeam 53 through a bearing, and the threaded column 532 protruding from the end of the crossbeam 53 is screwed into the threaded hole 534, so that the lifting plate 535 can be lifted or lowered relative to the crossbeam 53 by rotating the threaded column 532. In order to control the rotation of the threaded column 532, a sprocket 533 is arranged at the bottom of the threaded column 532 protruding from the crossbeam 53, and adjacent sprockets 533 are connected by a chain, so that the rotation of one threaded column 532 can control the synchronous rotation of the other threaded column 532, and thus the lifting plate 535 can be lifted or lowered relative to the crossbeam 53.

[0036] When the bottom steel 2 needs to be lifted, the crossbeam 53 is arranged through the perforation 21 of the bottom steel 2, and then the wheel body 51 is installed at both ends of the crossbeam 53. After the lifting mechanism 5 is assembled, the threaded column 532 is controlled to rotate, forcing the lifting plate 535 to rise until the lifting plate 535 contacts the top wall of the perforation 21 and the bottom of the bottom steel 2 is separated from the ground.

[0037] As shown in Figure 7 , Figure 8 , Figure 9 shown, in order to realize the adjustable improvement of the roller body and the rewinding shaft, the roller body and the rewinding shaft can be arranged as a plurality of spliced components. The diameters of the spliced components are the same, and thus the length of the roller body and the rewinding shaft can only be adjusted by disassembling and assembling the spliced components.

[0038] As shown in Figure 7 , specifically, the rewinding shaft 4 comprises two first spliced components 41 and a plurality of second spliced components 42, the plurality of second spliced components 42 are connected end to end, and the two first spliced components 41 are respectively spliced at both ends of the plurality of second spliced components 42. When the length of the rewinding shaft 4 needs to be changed, the number of the second spliced components 42 can be increased or decreased by disassembling. The roller body is arranged in the same manner as the rewinding shaft 4.

[0039] As shown in Figure 9As shown in the figure, in order to stably connect the second splicing piece 42, the plug-in pipe 43 is fixedly arranged at one end of the second splicing piece 42, and the plug-in slot 45 is arranged at the other end, and the annular groove is arranged on the side wall of the plug-in slot 45. The plug-in pipe 43 is inserted into the plug-in slot 45 of the adjacent second splicing piece 42, and the annular convex column installed on the plug-in pipe 43 is located in the annular groove, so that the plug-in pipe 43 and the second splicing piece 42 are buckled and connected, and the second splicing piece 42 can be conveniently disassembled according to the requirements.

[0040] As shown in the figure, Figure 8 In order to stably install the first splicing piece 41 at the end of the second splicing piece 42, the end shaft 44 is arranged at the end of the two first splicing pieces 41 away from each other, and the end shaft 44 can be conveniently installed on the frame body, thereby providing support for the work of the rewinding shaft 4. The plug-in slot 45 and the plug-in pipe 43 are arranged at the end of the first splicing piece 41 away from each other, and the first splicing piece 41 is connected with the adjacent second splicing piece 42.

[0041] As shown in the figure, Figure 1 , Figure 10 , Figure 11 In order to stably connect the adjacent splicing pieces, the parallel limiting rod group 3 can also be arranged at the bottom of the two splicing and connected parts of the frame body. The limiting rod group 3 includes the first column body 31, the stud 32 and the second column body 35. One end of the stud 32 is screwed into the first column body 31, and the other end of the stud 32 is provided with the rotating disc 34. The shaft body fixedly arranged on the end face of the rotating disc 34 is connected and inserted into the second column body 35 through the bearing. The ends of the second column body 35 and the first column body 31 away from each other are connected with the two parts of the frame body through bolts. Therefore, the relative movement of the first column body 31 and the second column body 35 can be controlled by rotating the stud 32, so as to force the relative movement of the two splicing and connected parts of the frame body, thereby providing support for changing the size of the machine body 1. At the same time, the adjusted machine body 1 can be stably placed under the action of the limiting rod group 3.

[0042] As shown in the figure, Figure 12 In order to control the synchronous adjustment of the rotating of the plurality of limiting rod groups 3, the rotating wheel 33 can be detachably arranged on each rotating disc 34. The rotating wheel 33 includes two half wheels 331, and the ear plate 332 is arranged on each half wheel 331. The stud can be penetrated through the ear plate 332, so that the two half wheels 331 can be spliced and sleeved on the rotating disc 34 under the action of the stud. The two rotating wheels 33 are connected through the belt, so that when one set of limiting rod groups 3 rotates, the other set of limiting rod groups 3 also rotates, thereby adjusting the size of the frame body.

[0043] In order to make the rotating wheel 33 and the rotating disc 34 rotate synchronously, the contact surfaces of the rotating disc 34 and the rotating wheel 33 are provided with a polygonal structure. In order to make the two half wheels 331 relatively stable splicing, the contact surfaces of the two half wheels 331 are respectively provided with the inserting column 333 and the inserting slot, and the inserting column 333 is inserted into the inserting slot.
