At this time, the driving effect of the motor can drive the magnetic roller to rotate at a uniform speed. At the same time, the reciprocating screw rod 14 can use the slide groove opened on its surface to make the sandblasting gun 15 move in the middle thereof, and the output of the sand in the material bin 13 can be used to sandblast the surface of the magnetic roller. The installation of the mounting seat 1 and the sandblasting bin 11 can simplify the operation process. At the same time, the sandblasting bin 11 is circular in design, and the internal side wall is a smooth plane, which can reduce the accumulation of sand after spraying, making it easier for the staff to clean the inside. At the same time, the surface opening of the sandblasting bin 11 is large, and the operation space is more convenient.

[0024] The above-mentioned limiting assembly includes a bottom limiting ring 2; the side wall of the above-mentioned bottom limiting ring 2 is rotatably connected to the top limiting ring 21; the side wall of the above-mentioned top limiting ring 21 is provided with a cushion block 22; the side wall of the above-mentioned top limiting ring 21 is fixedly connected with a plurality of groups of limiting rods 23; the side wall of the above-mentioned cushion block 22 is fixedly connected with a plurality of groups of sliding rods 26; the above-mentioned sliding rods 26 slide inside the bottom limiting ring 2, and the two are connected by a spring rod 25; the bottom of the above-mentioned bottom limiting ring 2 is fixedly connected with a limiting belt 24, and a through hole is opened in the middle of the limiting belt 24; when the staff installs the magnetic roller, the magnetic roller can be placed on the bottom limiting ring 2, and the magnetic roller can be limited by the rotation effect of the top limiting ring 21. At this time, when buying different specifications When a magnetic roller of a certain type is used, the pad 22 can maintain contact with the surface of the magnetic roller with the support of the elastic force of the spring rod 25. Then the staff can pull the limiting belt 24 to make it fit with one of the middle parts of the multiple groups of limiting rods 23, thereby completing the restriction of the bottom limiting ring 2 and the top limiting ring 21. The limiting effect of the top limiting ring 21 and the bottom limiting ring 2 can fix the magnetic roller. At the same time, when facing magnetic rollers of different specifications and thicknesses, the pad 22 can maintain the restriction on the end of the magnetic roller with the support of the elastic force of the spring rod 25, thereby increasing the adaptability of the equipment while increasing the friction force, thereby maintaining the positioning effect of magnetic rollers of different specifications and assisting in completing the sandblasting operation.

[0025] A connecting rod 3 is slidably connected to the middle of the rotating shaft 12; scrapers 31 are fixedly connected to the side walls of both sides of the connecting rod 3; a No. 1 support rod 32 is rotatably connected between the middle of the scraper 31 and the end of the connecting rod 3; a pair of rubber rods 33 are fixedly connected to the middle of the No. 1 support rods 32; after the surface sandblasting operation of the magnetic roller is completed inside the sandblasting chamber 11, the staff can drive the motor to drive the connecting rod 3 to rotate, so that the scraper 31 installed on the side wall of the connecting rod 3 is in contact with the inner side wall of the sandblasting chamber 11, and the sand material adhering to the side wall of the sandblasting chamber 11 is scraped off. During the movement, some sand materials adhere tightly. At this time, the elastic support effect of the rubber rod 33 can be used to make the scraper 31 partially displaced, so that the thrust on the sand materials is continuously increased and then scraped off. After scraping off the sand materials, the scraper 31 is reset and vibrates to loosen the sand materials on the surface of the scraper 31 and assist in falling. The rotating shaft 12 installed on the side wall of the rotating shaft 12 can assist the staff to clean the sand materials inside the sandblasting chamber 11 through the scraping effect of the scraper 31 after the sandblasting operation is completed, so as to reduce the continuous accumulation of sand materials inside the sandblasting chamber 11 and affect the subsequent use.

[0026] A No. 1 slide groove 4 is provided at the end of the connecting rod 3; rubber plates 41 are fixedly connected to both sides of the No. 1 slide groove 4, and the rubber plates 41 are arranged in a wave shape; an elastic rod 42 is fixedly connected to the bottom end of the No. 1 slide groove 4, and the other end of the elastic rod 42 is connected to the middle of the rubber rod 33; an air bag 43 is fixedly connected to the middle of the elastic rod 42, and the diameter of the air bag 43 is greater than the distance between the convex points of a pair of rubber plates 41; when the scraper 31 scrapes off the sand material on the side wall of the sandblasting chamber 11, it will encounter resistance when facing some sand material that is adhered, so that the scraper 31 drives the No. 1 support rod 32 to produce When the space between the middle parts of the pair of No. 1 support rods 32 is shortened, the rubber rod 33 will bend toward the middle part, thereby producing a pulling effect on the elastic rod 42, so that the position of the airbag 43 in the middle part of the elastic rod 42 is constantly in contact with the multiple groups of rubber plates 41, resulting in a frustration effect. When the scraper 31 cleans the side wall of the sandblasting chamber 11, when facing the adhered sand material, the contact between the elastic rod 42 and the rubber plate 41 can produce a frustration effect, causing the scraper 31 to shake, driving the scraper 31 and the adhered sand material to collide and contact for multiple times, driving the sand material to smoothly separate and reduce adhesion.

[0027] A No. 2 slide groove 6 is provided inside the above-mentioned roller 5; multiple groups of push plates 61 are slidably connected inside the above-mentioned No. 2 slide groove 6; the above-mentioned push plate 61 and the inner side wall of the roller 5 are connected through a spring column; multiple groups of brushes 65 are fixedly connected to the side wall of the above-mentioned push plate 61, and the brushes 65 pass through the side wall of the roller 5 and contact the side wall of the sandblasting chamber 11; multiple groups of limit plates 63 are fixedly connected to the middle part of the above-mentioned No. 2 slide groove 6; a rope 62 is installed between the above-mentioned No. 2 slide groove 6 and the limit plate 63 through a bearing; the above-mentioned rope 62 is connected to multiple groups of push plates 61; a ball 64 is placed inside the above-mentioned roller 5; in the process of the connecting rod 3 driving the scraper 31 to clean the sand material on the side wall of the sandblasting chamber 11, the roller 5 will contact and rotate with the side wall of the sandblasting chamber 11. At this time, as the angle changes, the ball 64 The second slide 6 will also move. At this time, under the pressure of the weight of the ball 64, the rope 62 will be squeezed and pulled, driving the push plate 61 to contract, so that the brush 65 will move, so that the brush 65 will discharge the sand in the gap through contact with the roller 5 during movement. At the same time, when the ball 64 moves to the position of the limit plate 63, the support effect provided by the limit plate 63 can make the push plate 61 reset under the effect of the spring column, so that the brush 65 and the side wall of the sand blasting chamber 11 are in contact, producing a cleaning effect. Through the rolling effect of the roller 5, the push plate 61 installed inside the roller 5 can drive the brush 65 to continuously contact the side wall of the sand blasting chamber 11, and perform secondary cleaning on the sand on the side wall, thereby increasing the cleaning effect and reducing the adhesion of the sand.

[0028] The side wall of the sandblasting gun 15 is fixedly connected with a driving block 7, and a brushless motor is fixedly connected inside the driving block 7; a positioning ring 72 is provided at the end of the driving block 7, and the positioning ring 72 is fixedly connected to the output end of the brushless motor; a plurality of groups of nozzles 71 are fixedly connected to the side wall of the positioning ring 72; when performing surface sandblasting on magnetic rollers of different specifications, since magnetic rollers of different specifications have different sizes and shapes, nozzles 71 of different diameters and specifications are sometimes required to be replaced to adapt to magnetic rollers of different models. At this time, the staff can drive the positioning ring 72 to rotate through the driving effect of the brushless motor installed inside the driving block 7, so that three different specifications of nozzles 71 and the sandblasting gun 15 can be installed, thereby changing the spraying effect of the sand material. Through the installation effect between the plurality of groups of nozzles 71 and the sandblasting gun 15, the nozzles 71 can be replaced according to magnetic rollers of different specifications, thereby increasing the adaptability of the equipment and reducing the cumbersome operation of manual replacement.

[0029] A pair of No. 3 slides 8 are provided at the bottom of the above-mentioned sandblasting chamber 11; a pair of No. 4 slides 82 are provided on the corresponding side walls of the above-mentioned mounting seat 1; a receiving plate 81 is slidably connected inside the above-mentioned No. 4 slide 82; the middle part of the above-mentioned receiving plate 81 slides to the bottom of the No. 3 slide 8; when the sandblasting gun 15 performs surface sandblasting on the toner cartridge, part of the sand material will be sprayed onto the sandblasting chamber 11. At this time, the fallen sand material will fall through the No. 3 slide 8 to the receiving plate 81 for storage. At the same time, in the process of the scraper 31 cleaning the sand material inside the sandblasting chamber 11, the auxiliary sand material smoothly enters the receiving plate 81, so as to facilitate the staff to subsequently uniformly process the sand material inside the receiving plate 81. Through the pair of No. 3 slides 8 opened at the bottom of the sandblasting chamber 11, the sand material inside the sandblasting chamber 11 can be guided into the receiving plate 81 for storage during the sandblasting and cleaning process, which is convenient for subsequent reuse and recycling.

[0030] The sandblasting chamber 11 is provided with a No. 5 chute 9 at both the upper and lower ends; a baffle 91 is slidably connected inside the No. 5 chute 9 on the top of the sandblasting chamber 11; when the staff cleans the sand inside the sandblasting chamber 11, the opening of the sandblasting chamber 11 can be closed by pulling down the baffle 91, so as to keep the material smoothly falling through the No. 3 chute 8 into the receiving plate 81 during the process of the scraper 31 cleaning the inside of the sandblasting chamber 11. The sealing effect of the baffle 91 can reduce the occurrence of sand splashing out of the opening of the sandblasting chamber 11 when cleaning the sand attached to the inside of the sandblasting chamber 11.

[0031] The side wall of the above-mentioned cushion block 22 away from the top limit ring 21 is fixedly connected with a rubber layer 101; when the cushion block 22 contacts the end of the magnetic roller during its movement, the rubber layer 101 installed on the side wall of the cushion block 22 can contact and fit with the end of the magnetic roller, and the rubber property is used to make it fit in contact with the magnetic roller. The rubber layer 101 installed on the side wall of the cushion block 22 can increase the friction with the magnetic roller, assist the magnetic roller to rotate, and increase the stability during the rotation process. At the same time, the rubber layer 101 can be deformed due to its own characteristics, and the fitting effect is increased when facing magnetic rollers of different specifications.

[0032] During the working process, when the staff processes the recycled toner cartridge, the magnetic roller inside the toner cartridge can be placed at the position of the rotating shaft 12, and the magnetic roller can be limited by the limiting component. At this time, the magnetic roller can be driven to rotate at a uniform speed through the driving effect of the motor. At the same time, the reciprocating screw rod 14 can use the slide groove opened on its surface to make the sandblasting gun 15 move in the middle thereof, and the surface of the magnetic roller can be sandblasted in coordination with the output of the sand material in the material bin 13. When the staff installs the magnetic roller, the magnetic roller can be placed on the bottom limiting ring 2, and the magnetic roller can be limited by the rotation effect of the top limiting ring 21. At this time, when buying a pair of magnetic rollers of different specifications and models, the pad 22 can maintain contact with the surface of the magnetic roller under the support of the elastic force of the spring rod 25. Then the staff can pull the limiting belt 24 to make it fit with one of the middle parts of the multiple groups of limiting rods 23 to complete the restriction of the bottom limiting ring 2 and the top limiting ring 21. After completing the surface sandblasting operation of the magnetic roller inside the sandblasting bin 11, the staff can order the motor The connecting rod 3 is driven to rotate, so that the scraper 31 installed on the side wall of the connecting rod 3 contacts the inner side wall of the sandblasting chamber 11, and the sand material adhering to the side wall of the sandblasting chamber 11 is scraped off. During the movement of the scraper 31, some sand material adheres tightly. At this time, the elastic support effect of the rubber rod 33 can be used to make the scraper 31 partially displaced, so that the thrust on the sand material is continuously increased and then scraped off. After scraping off the sand material, the scraper 31 resets and generates vibration, which shakes the sand material on the surface of the scraper 31. To loosen and assist the falling, when the scraper 31 scrapes off the sand on the side wall of the sandblasting chamber 11, it will encounter resistance when facing some of the sand that is adhered, so that the scraper 31 drives the No. 1 support rod 32 to move. At this time, as the distance between the middle parts of the pair of No. 1 support rods 32 shortens, the rubber rod 33 will bend toward the middle, thereby producing a pulling effect on the elastic rod 42, so that the position of the air bag 43 in the middle of the elastic rod 42 is constantly in contact with the multiple groups of rubber plates 41, producing a setback effect; In the process of the connecting rod 3 driving the scraper 31 to clean the sand on the side wall of the sandblasting chamber 11, the roller 5 will also move at the same time. At this time, the contact between the roller 5 and the sandblasting chamber 11 will produce rotation, causing the multiple groups of protrusions 52 installed on the side wall of the roller 5 to contact the side wall of the sandblasting chamber 11. Under the support effect of the No. 2 support rod 51 and the elastic rope 53, an elastic collision effect is generated, causing vibration. In the process of the connecting rod 3 driving the scraper 31 to clean the sand on the side wall of the sandblasting chamber 11, the roller 5 will contact and rotate with the side wall of the sandblasting chamber 11. At this time, as the angle changes, the ball 64 inside the No. 2 slide 6 will also move. At this time, under the pressure of its own weight, the rope 62 will be squeezed and pulled, driving the push plate 61 to contract , so that the brush 65 produces a moving effect, so that the brush 65 discharges the sand in the gap through contact with the roller 5 during movement. At the same time, when the ball 64 moves to the position of the limit plate 63, the support effect provided by the limit plate 63 can make the push plate 61 reset under the effect of the spring column, so that the brush 65 contacts the side wall of the sandblasting chamber 11 to produce a cleaning effect. When performing surface sandblasting on magnetic rollers of different specifications, because magnetic rollers of different specifications have different sizes and shapes, it is sometimes necessary to replace nozzles 71 of different diameters and specifications to adapt to magnetic rollers of different models. At this time, the staff can drive the positioning ring 72 to rotate through the driving effect of the brushless motor installed in the driving block 7, so that three different specifications of nozzles 71 and the sandblasting gun 15 can be installed, thereby changing the spraying effect of the sand. When the sandblasting gun 15 performs surface blasting on the toner cartridge, part of the sand will be sprayed onto the sandblasting chamber 11. At this time, the falling sand will fall through the No. 3 chute 8 to the receiving plate 81 for storage. At the same time, while the scraper 31 is cleaning the sand inside the sandblasting chamber 11, the auxiliary sand smoothly enters the receiving plate 81, so as to facilitate the staff to subsequently uniformly process the sand inside the receiving plate 81. When the staff cleans the sand inside the sandblasting chamber 11, the opening of the sandblasting chamber 11 can be closed by pulling down the baffle 91, so as to keep the material smoothly falling through the No. 3 chute 8 into the receiving plate 81 during the process of the scraper 31 cleaning the inside of the sandblasting chamber 11. When the pad 22 contacts the end of the magnetic roller during its movement, the rubber layer 101 installed on the side wall of the pad 22 can contact and fit with the end of the magnetic roller, and the rubber properties are used to make it fit and contact with the magnetic roller.
