[0002] Paper is a thin and soft material, mainly made of plant fibers (such as wood, grass, hemp, cotton, etc.) through mechanical or chemical treatment. In the papermaking process, the finished product slitting and sorting device is a key equipment, which is used to slit large-format paper into required specifications and sort it into neat paper stacks for subsequent packaging and transportation.
[0003] In paper production, finished paper needs to be cut. During cutting, the cutter is driven by a hydraulic cylinder to cut the paper. The cutter will wear out after working for a long time and needs to be replaced to maintain the cutting efficiency of the cutter. The traditional replacement method is to use tools to loosen or tighten the bolts. Although this method can achieve the replacement of the cutter, the operation is too cumbersome, time-consuming and labor-intensive, and reduces the cutting efficiency. Utility Model Content

[0026] When the slitting knife 19 needs to be replaced, first, by moving the handle 13, the movement of the handle 13 drives the external fixed moving rod 12 to move synchronously. The movement of the moving rod 12 further drives the fixed plate 10 fixed at the bottom to move, and the movement of the fixed plate 10 simultaneously drives the external fixed plug rod 15 to move. In the process of the fixed plate 10 driving the plug rod 15 to move, the first spring 14 sleeved on the outside of the moving rod 12 is squeezed, and the first spring 14 is deformed under the force. Then, when the plug rod 15 is completely moved out of the inside of the socket 17, the mounting column 18 and the slitting knife 19 can be taken out from the inside of the mounting block 6 for replacement. After completing the replacement of the slitting knife 19, insert the new or repaired mounting column 18 into the inside of the mounting block 6. At this time, the handle 13 is released, and under the reaction force of the first spring 14, the insertion rod 15 will be automatically pushed into the interior of the socket 17, thereby completing the installation, making it easy to replace the worn slitting knife 19. Different from the traditional replacement method of using tools to loosen or tighten the bolts, this operation method is simple and convenient, saving time and effort. By providing a collection box 25, it is convenient to collect the cut finished paper. The insertion rod 15 is connected to the socket 17 to improve the stability of the connection. The conveyor belt 26 is provided to facilitate the transportation of the finished paper. It is slidably connected to the outside of the two guide rods 8 through two guide rings 7, which plays a guiding role. The fixing rods 11 are fixedly connected on both sides of the U-shaped frame 9 to guide the fixed plate 10.
[0027] Reference Figure 3 The leveling assembly 23 includes a telescopic rod 2301, which is fixedly connected to the inside of the connecting block 22. A rotating plate 2303 is fixedly connected to the top of the telescopic rod 2301. A rotating rod 2304 is rotatably connected to the inside of the extension plate 21. The rotating plate 2303 is rotatably connected to the outside of the rotating rod 2304. A second spring 2302 is sleeved on the outside of the telescopic rod 2301. A handle 2305 is fixedly connected to the right side of the outside of the rotating plate 2303. A limiting rod 2307 is fixedly connected to the left side of the outside of the rotating plate 2303. A leveling roller 2306 is rotatably connected to the lower part of the rotating plate 2303. An annular groove 24 is opened on the outside of the extension plate 21, and the limiting rod 2307 is slidably connected to the inside of the annular groove 24.
[0028] When the finished paper is cut, first, the finished paper in a roll is placed outside the support plate 2 to ensure that the finished paper can be smoothly unfolded and transported. Then, the operator moves the handle 2305 upward, and the movement of the handle 2305 drives the externally fixed rotating plate 2303 to rotate outside the rotating rod 2304. As the rotating plate 2303 moves, the flattening roller 2306 connected to the lower part also moves, and in this process, the telescopic rod 2301 fixed outside the rotating plate 2303 is squeezed. The telescopic rod 2301 contracts when being squeezed, and at the same time drives the second spring 2302 sleeved outside it to be squeezed and compressed. Next, when the flattening roller 2306 moves away from the upper part of the conveyor belt 26 to a certain position, the operator passes one end of the finished paper through the lower part of the flattening roller 2306. At this time, the handle 2305 is released, and under the reaction force of the second spring 2302, the flattening roller 2306 automatically returns to its position and fits with the upper part of the finished paper, thereby achieving the flattening of the finished paper. After the flattening is completed, the finished paper is conveyed by the conveyor belt 26. During the conveying process, the flattening roller 2306 is in continuous contact with the finished paper to ensure that the surface of the paper remains flat. In this way, the flattened paper can maintain consistency and stability in subsequent processing, such as slitting, printing and other operations. Such flattened paper reduces the failure and scrap rate during processing, and improves production efficiency and product quality.
[0029] Working principle: When the slitting knife 19 needs to be replaced, first, the handle 13 is moved, and the handle 13 moves with the external fixed moving rod 12, and the moving rod 12 moves with the bottom fixed fixed plate 10, and the fixed plate 10 moves with the external fixed plug rod 15. When the fixed plate 10 moves with the plug rod 15, the first spring 14 sleeved on the outside of the moving rod 12 is squeezed, so that the first spring 14 is deformed by force, and then, when the plug rod 15 moves out of the inside of the socket 17, the installation can be The column 18 and the slitting knife 19 are moved from the inside of the mounting block 6 for replacement. When installing, the mounting column 18 is inserted into the inside of the mounting block 6, the grip 13 is loosened, and the insertion rod 15 is inserted into the inside of the insertion hole 17 under the reaction force of the first spring 14, so that the worn slitting knife 19 can be easily replaced. The difference from the traditional replacement method is to use tools to loosen or tighten the bolts. This operation method is simple and convenient, saving time and effort. Then, when slitting the finished paper, first, put the finished paper into the roll. On the outside of the support plate 2, then, move the handle 2305 upward, the handle 2305 moves and the externally fixed rotating plate 2303 rotates outside the rotating rod 2304, when the rotating plate 2303 moves, it moves the leveling roller 2306 connected to the lower rotation, and at the same time squeezes the telescopic rod 2301 fixed on the outside of the rotating plate 2303, when the telescopic rod 2301 contracts, it squeezes the second spring 2302 set on the outside, and then, when the leveling roller 2306 is pulled from the upper part of the conveyor belt 26 When moving away, pass one end of the finished paper through the lower part of the leveling roller 2306, then release the handle 2305, and under the reaction force of the second spring 2302, the leveling roller 2306 can be fitted with the upper part of the finished paper, and then the finished paper can be transported by the conveyor belt 26. In the process of conveying the finished paper, the finished paper can be leveled. The flattened paper can maintain consistency and stability during subsequent processing (such as slitting, printing, etc.), reducing failures and scrap rates during processing.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
