Description

Technical Field

[0001] This invention relates to the field of plasma cutting technology, and more specifically, to a cutting device for processing grinding disc liners. Background Technology

[0002] Grinding disc liners are an important component in grinding equipment, typically located on the inner wall of the grinding disc. They protect the disc and improve its wear resistance, primarily reducing wear, extending the grinding disc's lifespan, and improving grinding efficiency and product quality. During the liner processing, the liner needs to be cut, and the most commonly used cutting equipment is the plasma cutting machine. Plasma cutting utilizes the high temperature and energy of plasma for cutting. It generates plasma discharge on the material surface, causing localized heating and dissolution. Then, gas jets disperse the dissolved material, achieving the cutting process.

[0003] However, existing plasma cutting machines still have some problems in actual use. For example, during the cutting process of the liner, existing plasma cutting machines generate a large amount of debris and harmful fumes. These debris, similar to sparks, scatter and land on the surface of the liner and the cutting machine. After cooling, they turn into slag. Existing plasma cutting machines generally clean up the debris after the cutting is completed, and cannot collect the debris during the cutting process. This causes the debris to fall onto the liner during the cutting process, thus affecting the subsequent cutting quality. Summary of the Invention

During the rotation of gears 1005, gears 1004 can be driven to rotate, thereby causing the pressure rollers 1003 inside the main frame 1001 to rotate. At this time, the liner to be cut is inserted into the main frame 1001. Through the rotation and compression of the two perpendicularly adjacent pressure rollers 1003, the liner is flattened, thereby achieving the purpose of flattening the liner, improving subsequent cutting operations, and avoiding the problem of poor cutting effect caused by cutting the liner when it is uneven.

[0025] A fixing plate 39 is provided on one side of the motor 1008. The motor 1008 is fixedly installed inside the support frame 11.

During the motion, it can drive the gear 41 to move downward under the action of the connecting rod 43. During the movement, it can cause the gear 41 to rotate under the action of the toothed plate 42.

Then, the air enters the air distribution frame 56 through the exhaust pipe 32, and finally sprays it into the main frame 1001 through multiple nozzles 57 on the bottom surface of the air distribution frame 56. This achieves the purpose of cleaning the surface of the liner during the flattening process, avoiding the problem of dust and impurities on the surface of the liner affecting the subsequent cutting effect.

[0028] Specifically, the working process or working principle of the cutting equipment for grinding disc liner processing is as follows: When in use, first prepare the liner material to be cut, and then start the motor 1008. After the motor 1008 starts, the pulley 1006 and the transmission belt 1007 will drive the two parallel adjacent gears 1005 to rotate. During the rotation of gear 1005, it can drive gear 1004 to rotate, thereby causing the various pressure rollers 1003 inside the main frame 1001 to rotate. At this time, the liner to be cut is inserted into the interior of the main frame 1001. Under the rotation and squeezing of the two perpendicularly adjacent pressure rollers 1003, the liner is flattened. After being flattened, the liner is conveyed by the pressure roller 1003 and falls onto the top surface of the placement plate 8. The liner is then placed in the center of the top surface of the placement plate 8, and cutting can begin. During cutting, the plasma cutter 6 is started, and the plasma gas inside the plasma cutter 6 is delivered to the plasma cutting head 5 through the gas supply pipe 7. The plasma gas is ignited by the spark generator inside the plasma cutting head 5 and comes into contact with the cutting flame. As the moving frame 3 moves the plasma cutting head 5, it cuts the liner placed above the placement plate 8. During cutting, debris is ejected. At this time, the suction fan 20 is started, generating suction that draws the debris and harmful fumes generated during cutting through the adsorption plate 13 and adsorption frame 12 into the connecting pipe 14. From there, the debris is conveyed through the connecting pipe 14 to the rectangular pipe 15, and finally into the conveying pipe 16. When pipe 16 enters the interior of box 17, it is blocked by filter frame 30 and falls to the bottom of box 17 under its own weight. When harmful smoke passes through filter frame 30 and purification frame 31, the harmful substances in the harmful smoke are adsorbed by purification frame 31 to purify the harmful smoke during cutting. When harmful smoke and debris enter the interior of box 17, since discharge pipe 26 is fixedly installed on the bottom surface of box 17, and rotating shaft 27 is rotatably installed inside discharge pipe 26, and spiral blades 28 are installed on the outer surface of rotating shaft 27, and one end of rotating shaft 27 extends to the air outlet of conveying pipe 16, when harmful smoke enters the interior of purification tank 18 through box 17, it will blow fan blades 29 to drive rotating shaft 27 to rotate. During the rotation of rotating shaft 27, the debris that falls to the bottom of box 17 can be conveyed downward through spiral blades 28 and fall into collection box 22 for unified collection. When the motor 1008 starts, it can drive the connecting shaft 44 to rotate. During the rotation of the connecting shaft 44, it can drive the connecting rod 45 to perform a circular motion on one side surface of the fixed plate 39. During the motion, it can drive the gear 41 to move downward under the action of the connecting rod 43. During the movement, it can cause the gear 41 to rotate under the action of the toothed plate 42. During the rotation, it can drive the toothed plate 40 to move downward, thereby driving the crossbar 51 to move downward. During the downward movement of the crossbar 51, it can drive the pressure plate 23 to move downward inside the collection box 22. The debris falling through the spiral blade 28 will first fall to the top surface of the pressure plate 23, and then roll down to the bottom surface of the collection box 22 through the slope of the top surface of the pressure plate 23. When the debris inside the collection box 22 is collected to a certain height, the debris will be compacted during the downward movement of the pressure plate 23. Furthermore, as the toothed plate 40 moves downward, it also drives the connecting rod 35 downward. As the connecting rod 35 moves downward, it drives the plug disc 34 downward inside the cylinder 33, compressing the air inside the cylinder 33 into the exhaust pipe 32. Then, the air enters the air distribution frame 56 through the exhaust pipe 32, and finally, it is sprayed into the main frame 1001 through multiple nozzles 57 on the bottom surface of the air distribution frame 56 to clean the surface of the liner during the flattening process. With the circumferential movement of the connecting shaft 44, when the toothed plate 40 descends to a certain extent, it can drive the toothed plate 40 upward. During the upward movement, air can be drawn back into the cylinder 33 through the air inlet pipe 37. It can also drive the pressure plate 23 upward inside the collection box 22, so that the newly fallen debris on the top of the pressure plate 23 can enter the collection box 22. Then, when the pressure plate 23 moves downward, it is pressed again.

[0029] It should be noted that the motor 1008 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail here.
