[0006] 1. During the use of traditional sandblasting equipment, metal oxides from the surface of the shaft will continue to mix into the sand during long-term sandblasting operations. If these metal oxides cannot be filtered in time, it will not only affect the spraying performance of the sand, resulting in unstable sandblasting effects, but also may cause additional wear on key components such as the nozzle and pipeline of the sandblasting device due to factors such as hardness differences, shortening the service life of the equipment and increasing maintenance costs;

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the processing of spinning machine shafts, sandblasting is an important process, the purpose of which is to remove impurities and oxide layers on the shaft surface, improve surface roughness, and enhance the adhesion of subsequent coatings. At present, during the use of traditional sandblasting devices, metal oxides from the shaft surface will continue to mix into the sand body during long-term sandblasting operations. If these metal oxides cannot be filtered in time, it will not only affect the spraying performance of the sand body, resulting in unstable sandblasting effects, but also may cause additional wear on key components such as the nozzle and pipeline of the sandblasting device due to factors such as hardness differences, shortening the service life of the equipment and increasing maintenance costs.

[0041] The purpose of this embodiment is to provide a sandblasting device for processing a spinning machine shaft. Figure 1-Figure 8 As shown, it includes a body 100, the bottom of the body 100 is in a slope shape, a through groove 101 is provided at the bottom of the body 100, a collecting box 102 is provided below the through groove 101, and the collecting box 102 is used to collect glass sand, a sandblasting component 300 is provided on the inner wall of the body 100, and the sandblasting component 300 is used to perform sandblasting on the surface of the other rotating shaft, clamping components 400 are provided on both sides below the sandblasting component 300, and the clamping components 400 are used to clamp and fix the rotating shaft, and a debris removal component 500 is provided in the through groove 101, and the debris removal component 500 is used to absorb metal impurities mixed in the sand body, and at the same time, the debris removal component 500 drives the clamping component 400 to rotate, so that the sandblasting component 300 evenly sandblasts the surface of the clamping component 400.

[0042] By arranging the electromagnetic roller 502 in the through groove 101, when the output shaft of the rotating motor 501 drives the electromagnetic roller 502 to rotate, the electromagnetic roller 502 adsorbs the metal oxides. At the same time, the plurality of grooves 503 arranged in a row on the surface of the electromagnetic roller 502 can slow down the speed of the sand body flowing out of the through groove 101, and at the same time can increase the contact area with the sand body, so that the sand body and the electromagnetic roller 502 are fully in contact, thereby improving the efficiency of removing the metal oxides in the sand body, facilitating the reuse of the sand body, and saving production costs.

[0043] Considering that in the process of sandblasting the rotating shaft, in order to avoid the discontinuity of the sandblasting path, the path is adjusted several times during the sandblasting process. Therefore, the sandblasting assembly 300 includes a servo motor 301 arranged on one side of the machine body 100, the output shaft of the servo motor 301 passes through the machine body 100 and is provided with a screw rod 302 at the end. The surface of the screw rod 302 is provided with a sandblasting assembly 300, and when the screw rod 302 rotates, it drives the moving plate 303 to move in the horizontal direction. A sandblasting machine 304 is provided on the top of the machine body 100, and the end of the sandblasting machine 304 is connected to a nozzle 303 through a connecting pipe. 05. The nozzle 305 is fixed at the bottom of the movable plate 303. When the movable plate 303 moves, the nozzle 305 is driven to move horizontally. During the sandblasting process, the output end of the servo motor 301 is controlled to drive the screw rod 302 to rotate. When the screw rod 302 rotates, the movable plate 303 is driven to move in the horizontal direction. The nozzle 305 provided at the bottom of the movable plate 303 moves in a horizontal straight line following the movable plate 303, so as to continuously sandblast the surface of the rotating shaft placed under the nozzle 305, avoid path discontinuity during the sandblasting process, and thus improve the sandblasting efficiency of the rotating shaft.

[0044] When the rotating shaft is sandblasted, it is necessary to fix the rotating shaft horizontally. In order to facilitate the fixing of the rotation, the clamping assembly 400 includes a frame plate 401 that rotates on the inner wall of the machine body 100. The frame plate 401 is provided with a column 402 at the top and bottom. A slide column 403 is slidably provided on the inner wall of the column 402. A return spring 404 is provided between the column 402 and the slide column 403. An arc-shaped block is provided at the end of the slide column 403. The arc-shaped block is adapted to the diameter of the rotating shaft to be sandblasted. The movable sliding column 403 slides on the inner wall of the column tube 402. During the movement of the sliding column 403, the return spring 404 is squeezed, so that the sliding columns 403 at both ends of the frame plate 401 move away from each other, and the end of the rotating shaft is placed in the arc-shaped block provided at the end of the sliding column 403. When the rotating shaft is placed, the sliding column 403 is stopped from being pushed. The sliding column 403 is squeezed and fixed at the top and bottom of the rotating shaft end by the force of the return spring 404, thereby realizing rapid fixation of the rotating shaft.

[0045] Considering that the shaft fixed in the arc-shaped block is in the process of sandblasting, when the frame plate 401 drives the shaft to rotate inside the machine body 100, the slide column 403 is subjected to the centrifugal force and drives the arc-shaped block to move in the direction of separation, thereby causing the shaft fixed on the inner wall of the slide column 403 to loosen and fall off, which may easily cause the shaft to collide and deform, thus affecting the processing quality of the shaft. Therefore, slide grooves are provided on both sides of the surface of the column 402, and extension tooth blocks 405 are provided on both sides of the top of the slide column 403. The extension tooth blocks 405 slide against the inner wall of the extension tooth blocks 405. The relative position of the slide column 403 can be adjusted by limiting the extension tooth blocks 405. Fixed plates are provided on both sides of the frame plate 401, and cylinders 406 are provided at the ends of the fixed plates. The piston rod at the ends of the cylinders 406 is provided with The toothed plate 407 controls the piston rod to drive the toothed plate 407 to move relative to each other. The toothed plate 407 is used to limit the extended tooth block 405. In the natural state, when the arc-shaped block provided at the end of the slide post 403 completes the fixation of the end of the rotating shaft, the extended tooth block 405 provided at the top of the slide post 403 moves to a stable position. The piston rod at the end of the control cylinder 406 drives the toothed plate 407 to move horizontally, so that the end of the toothed plate 407 fixes the position of the extended tooth block 405, thereby fixing the position of the slide post 403, and the arc-shaped block provided at the end of the slide post 403 fixes the rotating shaft, so as to prevent the slide post 403 from loosening due to the centrifugal force, improve the stability of the sandblasting operation, and prevent the rotating shaft from falling during the sandblasting operation, thereby ensuring the sandblasting quality of the rotating shaft.

[0046] Considering that when the sand body impacts the surface of the rotating shaft during the sandblasting process, the sand body is forced to spray toward the top of the machine body 100, in order to prevent the sand body from adhering to the inner wall of the machine body 100, a baffle 200 is provided inside the machine body 100, and the baffle 200 is symmetrically arranged on both sides of the nozzle 305. When the sand body contacts the surface of the rotating shaft, a strong impact force will be generated. According to the momentum theorem, the high-speed moving sand body has a large momentum, and collides with the surface of the rotating shaft in a very short time, and the momentum changes sharply, generating a large impact force, which will cause the sand body to receive a reaction force to the surroundings at the collision point, thereby scattering to the surroundings. By arranging baffles 200 on both sides of the nozzle 305, the baffle 200 blocks the scattered sand body, thereby preventing the sand body from adhering to the inner wall of the machine body 100, and ensuring the cleanliness of the inside of the machine body 100.

[0047] Considering that the shape of the sand particles is not completely regular when the sand body is used for sandblasting on the surface of the rotating shaft, they will also produce grinding and scraping effects while impacting the surface of the rotating shaft. When these irregular sand particles come into contact with metal oxides, they will grind and scrape the metal oxides like tiny files. As the sandblasting continues, the sand particles will continuously pass through the surface of the metal oxides, gradually grinding and scraping off the metal oxides bit by bit. In order to reuse the sand body, it is necessary to remove the metal oxides mixed in the sprayed sand body. Therefore, the impurity removal component 500 includes a groove 503 provided in the through groove 101, and the groove 503 is used to adsorb the metal impurities mixed in the sand body passing through the through groove 101. A rotating motor 501 is provided on one side of the bottom of the body 100, and an electromagnetic roller 502 is provided at the output end of the rotating motor 501. The side wall of the electromagnetic roller 502 is provided with grooves 503, and the grooves 503 are arranged in a row on the surface of the electromagnetic roller 502 in a ring shape. By arranging an electromagnetic roller 502 in the through groove 101, when the output shaft of the rotating motor 501 drives the electromagnetic roller 502 to rotate, the metal oxide is adsorbed by the electromagnetic roller 502. At the same time, the multiple grooves 503 arranged in a row on the surface of the electromagnetic roller 502 can slow down the speed of the sand body flowing out of the through groove 101, and at the same time can increase the contact area with the sand body, so that the sand body and the electromagnetic roller 502 are fully in contact, thereby improving the efficiency of removing the metal oxide in the sand body, facilitating the reuse of the sand body, and saving production costs. When the shaft sandblasting is completed, the collection box 102 is pulled out and the filtered sand body is taken out for secondary utilization. By cutting off the power to the electromagnetic roller 502, the metal oxide adsorbed on the surface of the electromagnetic roller 502 falls and is collected, thereby quickly filtering the mixed metal oxides in the sand body.

[0048] When the sand body is sandblasted, in order to improve the uniformity and efficiency of the sandblasting, a rotating motor 501 is provided on the side wall of the body 100, and the output end of the rotating motor 501 is fixed to the end of the electromagnetic roller 502. A belt roller 504 is provided between the rotating motor 501 and the electromagnetic roller 502. The surface of the belt roller 504 is connected to the end of the frame plate 401 through a transmission belt. When the output end of the rotating motor 501 drives the electromagnetic roller 502 to rotate to remove the metal oxides in the sand body, the output end of the rotating motor 501 drives the belt roller 504 to rotate coaxially. When the belt roller 504 rotates, it drives the frame plate 401 to rotate on the inner wall of the body 100 through the transmission, so that the rotating shaft clamped in the arc block rotates, thereby ensuring the uniformity of the sandblasting process of the rotating shaft and improving the sandblasting quality of the rotating shaft.

[0049] When in use, the sliding column 403 is pushed to slide on the inner wall of the column tube 402. The sliding column 403 squeezes the return spring 404 during its movement, so that the sliding columns 403 at both ends of the frame plate 401 move away from each other, and the end of the rotating shaft is placed in the arc-shaped block provided at the end of the sliding column 403. When the rotating shaft is placed, the sliding column 403 is stopped from being pushed. The sliding column 403 is pressed and fixed at the top and bottom of the rotating shaft end by the force of the return spring 404, thereby realizing the rapid fixation of the rotating shaft.

[0050] When the arc-shaped block at the end of the slide post 403 has completed fixing the end of the rotating shaft, the extended tooth block 405 at the top of the slide post 403 moves to a stable position, and the piston rod at the end of the control cylinder 406 drives the tooth plate 407 to move horizontally, so that the end of the tooth plate 407 fixes the position of the extended tooth block 405, thereby fixing the position of the slide post 403, and the arc-shaped block at the end of the slide post 403 fixes the rotating shaft, preventing the slide post 403 from loosening due to the centrifugal force, thereby improving the sandblasting operation. Stability, to prevent the shaft from falling during the sandblasting operation, thereby ensuring the sandblasting quality of the shaft. After the shaft is clamped, the output end of the servo motor 301 is controlled to drive the screw 302 to rotate. When the screw 302 rotates, it drives the moving plate 303 to move in the horizontal direction. The nozzle 305 provided at the bottom of the moving plate 303 moves in a horizontal straight line following the moving plate 303, thereby continuously sandblasting the surface of the shaft placed under the nozzle 305, avoiding path discontinuity during the sandblasting process, thereby improving the sandblasting efficiency of the shaft;

[0051] By arranging an electromagnetic roller 502 in the through groove 101, when the output shaft of the rotating motor 501 drives the electromagnetic roller 502 to rotate, the electromagnetic roller 502 adsorbs the metal oxide. At the same time, the multiple grooves 503 arranged in a row on the surface of the electromagnetic roller 502 can slow down the speed of the sand body flowing out of the through groove 101, and at the same time can increase the contact area with the sand body, so that the sand body and the electromagnetic roller 502 are fully in contact, thereby improving the efficiency of removing the metal oxide in the sand body, facilitating the reuse of the sand body, and saving production costs. When the output end of the rotating motor 501 drives the electromagnetic roller 502 to rotate to remove the metal oxide in the sand body, the output end of the rotating motor 501 drives the belt roller 504 to rotate coaxially. When the belt roller 504 rotates, it drives the frame plate 401 to rotate on the inner wall of the body 100 through transmission, so that the rotating shaft clamped in the arc block rotates, thereby ensuring the uniformity of the sandblasting process of the rotating shaft and improving the sandblasting quality of the rotating shaft.
