Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to a paper cutting mechanism for a high-speed printer. Background Technology

[0002] High-speed printers are widely used in office, industrial, and commercial settings, and the paper cutting mechanism is one of its key components. The paper cutting mechanism is responsible for precisely cutting the printed paper to the predetermined size to ensure neat and aesthetically pleasing output documents.

[0003] Most existing high-speed printers use a slicing blade to cut the paper, which is time-consuming and inefficient. When cutting the paper, burrs and paper scraps are easily generated. There is a lack of automatic cleaning devices, and paper scraps and debris can easily accumulate in the cutting blade and the cutting groove, affecting the cutting effect and blade life. In addition, some papers are highly flexible, and if they are not pressed and fixed, they will be skewed. During cutting, the blade edge and the paper cut are subjected to great force, which makes it easy to cut at an angle. Utility Model Content

[0004] The purpose of this invention is to provide a paper cutting mechanism for a high-speed printer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper cutting mechanism for a high-speed printer, including a printer, a paper cutting mechanism being provided at one end of the printer, the paper cutting mechanism including a processing box, the processing box being fixed to one end of the printer;

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention discloses a paper cutting mechanism for a high-speed printer. By rotating a rotating rod, the movable blade reciprocates. When the movable blade cuts the paper, the pressure plate first contacts the paper, then presses and fixes the paper against the fixed blade. A spring sleeve then lifts the pressure plate, allowing the movable blade to contact the paper and cut. This increases the rigidity of the blade edge and the paper cut, preventing any impact on the cutting effect. After cutting, an eccentric wheel lifts the fixed box, and the spring sleeve pushes the pressure plate back to its original position. Simultaneously, a cleaning brush removes residual paper scraps and debris from the movable blade, preventing clogging and extending the blade's lifespan. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see the appendix Figure 1-4 This application provides the following technical solutions.

[0021] A paper cutting mechanism for a high-speed printer includes a printer 1. A paper cutting mechanism 2 is provided at one end of the printer 1. The paper cutting mechanism 2 includes a processing box 21, which is fixed to one end of the printer 1. Rotating rods 26 are rotatably connected to both sides of the inner wall of the processing box 21. A cutting component 27 is fixedly connected to the outer wall of the rotating rods 26. The cutting component 27 includes an eccentric wheel 271. Two bearings 272 are fixedly connected to the outer wall of the eccentric wheel 271. Connecting components 273 are fixedly connected to the outer walls of both bearings 272. The bottom of the two connecting components 273... The part is rotatably connected to a fixed box 274. A movable blade 277 is fixedly connected to the bottom of the fixed box 274. A spring sleeve 2710 is fixedly connected to the bottom of the fixed box 274. A pressure plate 278 is fixedly connected to the bottom of the spring sleeve 2710. One side of the inner wall of the pressure plate 278 is in contact with the movable blade 277. The bottom plane of the pressure plate 278 is lower than the bottom plane of the movable blade 277. A cleaning bristle 279 is fixedly connected to one side of the inner wall of the threaded rod 28. The cleaning bristle 279 is in contact with one side of the movable blade 277.

[0022] It should be noted that during cutting, the motor drives the rotating rod 26 to rotate, which in turn drives the eccentric wheel 271 to rotate. When the eccentric wheel 271 rotates, the bearing 272 causes the connecting piece 273 to reciprocate up and down. The connecting piece 273 then drives the fixed box 274 to reciprocate, which in turn drives the movable blade 277 to reciprocate, cutting the paper. When the movable blade 277 moves downwards, because the bottom of the pressure plate 278 is lower than the movable blade 277, the pressure plate 278 contacts the paper first, causing the limiting side plate 210 to contract and generate spring. The paper is pressed and fixed by the pressure plate 278 and the fixed blade 23, which increases the rigidity of the cutting edge of the movable blade 277 and the paper cut during cutting. Then the movable blade 277 contacts the paper to cut. After cutting, the fixed box 274 drives the movable blade 277 to rise, and the limiting side plate 210 releases elastic potential energy, pushing the pressure plate 278 to reset. The pressure plate 278 drives the cleaning bristles 279 to move and clean the paper scraps attached to the surface of the movable blade 277, preventing the gap between the movable blade 277 and the fixed blade 23 from being blocked and avoiding affecting the service life of the blade.

[0023] The processing box 21 has a paper outlet on its side wall connected to the printer 1. A limiting base plate 22 is fixedly connected to the bottom of the paper outlet. A fixed blade 23 is fixedly connected to the top of the limiting base plate 22. One side of the fixed blade 23 is in contact with the movable blade 277. A threaded rod 28 is rotatably connected inside the processing box 21. A handle 29 is fixedly connected to one end of the threaded rod 28 that passes through the processing box 21. Two limiting side plates 210 are threadedly connected to the outer wall of the threaded rod 28. The bottom of the two limiting side plates 210 is in contact with the limiting base plate 22. A guide plate 24 is fixedly connected to the bottom of the limiting base plate 22. A placement opening is opened on one side of the processing box 21. A placement plate 25 is provided on the placement opening. The guide plate 24 is connected to the placement opening. A top cover plate 211 is rotatably connected to the top of the processing box 21.

[0024] It should be noted that during use, the operator first opens the placement plate 25 and places it horizontally, then rotates the handle 29. The handle 29 drives the threaded rod 28 to rotate, causing the threaded rod 28 to move in a threaded motion with the limiting side plate 210. This causes the two limiting side plates 210 to slide towards each other along the top of the limiting base plate 22 until they reach the width of the paper to be printed. The paper to be printed is then placed into the printer 1 for processing. After printing, the paper is discharged from the paper outlet and flows along the top of the limiting base plate 22 into the space between the two limiting side plates 210. Guided by the limiting side plates 210, the paper reaches the top of the fixed blade 23. Through the shearing force of the cutting element 27 and the fixed blade 23, the paper is cut and falls onto the guide plate 24, then slides along the guide plate 24 to the top of the placement plate 25. If there is a problem with the cutting, the operator can open the top cover 211 to adjust the inside of the processing box 21.

[0025] In use, the operator first opens the placement plate 25 and places it horizontally. Then, the operator rotates the handle 29, which drives the threaded rod 28 to rotate, causing the threaded rod 28 to move threadedly against the limiting side plate 210. This causes the two limiting side plates 210 to slide towards each other along the top of the limiting base plate 22 until they reach the width of the paper to be printed. The paper is then placed into the printer 1 for processing. After printing, the paper exits from the paper outlet, flows along the top of the limiting base plate 22, and enters between the two limiting side plates 210. Guided by the limiting side plates 210, the paper reaches the top of the fixed blade 23. The cutting element 27 cuts the paper with the shearing force of the fixed blade 23, causing it to break and fall onto the guide plate 24. The paper then slides along the guide plate 24 to the top of the placement plate 25. If cutting problems occur, the operator can adjust the inside of the processing box 21 by opening the top cover 211. During cutting, the motor drives the rotating rod 26 to rotate, which in turn drives the eccentric wheel 271 to rotate. 1. During rotation, the bearing 272 causes the connector 273 to reciprocate up and down, which in turn drives the fixed box 274 to reciprocate. The fixed box 274 then drives the movable blade 277 to reciprocate to cut the paper. When the movable blade 277 moves downward, since the bottom of the pressure plate 278 is lower than the movable blade 277, the pressure plate 278 contacts the paper first. The limiting side plate 210 contracts to generate elastic potential energy, and the pressure plate 278 and the fixed blade 23 press the paper together to fix it, improving the rigidity of the cutting edge of the movable blade 277 and the paper cut during cutting. Subsequently, the movable blade 277 contacts the paper to cut. After cutting, the fixed box 274 drives the movable blade 277 to rise, and the limiting side plate 210 releases elastic potential energy, pushing the pressure plate 278 back to its original position. The pressure plate 278 drives the cleaning brush 279 to move and clean the paper scraps attached to the surface of the movable blade 277, preventing the gap between the movable blade 277 and the fixed blade 23 from becoming clogged and affecting the service life of the blade.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
