Description

Technical Field

[0001] The invention belongs to the technical field of shot blasting machines, and in particular relates to a shot-residue separation device for shot blasting machines. Background Art

[0002] Related technologies include a shot-residue separation device for a shot blasting machine disclosed in application publication number CN215964798U, in which a filter plate bracket mounting groove is provided on the front end surface of the separation device body, the filter plate bracket mounting groove extends to the interior of the separation device body, a filter plate is provided on the outside of the separation device body, filter plate mounting grooves are provided on the four end corners of the upper end surface of the filter plate, the filter plate mounting groove passes through the filter plate, and a filter plate mounting groove is provided on both sides of the outer surface of the filter plate mounting bracket.

[0003] When the above device is filtering the pellets, it performs filtering operation through the filter plate. However, during the filtering process, the burrs, rust or surface dirt on the surface of the parts being shot blasted are uneven in size, which may cause the pellets to fall and be removed along with the pellet residue during the filtration, resulting in waste. Alternatively, the pellet residue may be collected along with the pellets and shot blasted again, resulting in damage to the surface of the parts. This has great limitations. Summary of the invention

By setting a separation mechanism, when the projectiles are sprayed by the shot blasting machine, the projectiles will fall into the bottom groove. Due to gravity, the inclined bottom groove drives the projectiles to move to the right. When the projectiles pass through the surface of the small square grooves with a width smaller than that of the projectiles, the small projectile residues will fall from the small square grooves to the inside of the waste bin for preliminary separation, thereby solving the problem that the projectiles will also fall and be discharged together with the projectile residues in the existing filtration, causing waste, or the projectile residues will be collected together with the projectiles and shot blasted again, thereby causing damage to the surface of the parts.

[0010] Furthermore, an extension plate is fixedly connected to the left side of the front end of the first baffle, a motor is fixedly connected to the top of the extension plate, a roller is fixedly connected to the output end of the motor, a track is transmission-connected to the outer wall of the output end of the motor, the inner surface of the track is transmission-connected to the front end of the roller, the bottom of the extension plate is fixedly connected to the bottom groove, a first rectangular opening is opened on the right side of the bottom of the inner wall of the bottom groove, a small square groove is opened at the bottom of the inner wall of the bottom groove, a waste bin is fixedly connected to the bottom of the bottom groove, a second baffle is hinged on the front end of the outer wall of the first baffle, a handle is fixedly connected to the front end of the second baffle, and a placement plate is fixedly connected to the right side of the top of the bottom groove.

[0011] Furthermore, the pulley assembly includes a push rod fixedly connected to the bottom of the screening plate, the bottom of the push rod is fixedly connected to a piston plate, the outer wall of the piston plate is slidably connected to a hollow column, the bottom of the inner wall of the hollow column is fixedly connected to a spring, the top of the spring is fixedly connected to the bottom of the piston plate, and the bottom of the hollow column is rotatably connected to a roller.

[0012] Furthermore, a shot blasting mechanism is provided at the top of the inner wall of the top shell, and the shot blasting mechanism includes a rotating column rotatably connected to the top of the inner wall of the top shell, a fixed plate is fixedly connected to the bottom of the rotating column, a shunt pipe is fixedly connected to the bottom of the fixed plate, the front end and the rear end of the shunt pipe respectively pass through the front end and the rear end of the fixed plate, the ends of the two shunt pipes away from the fixed plates are connected and fixed with a shot blasting machine, and the bottoms of the two shot blasting machines are connected and fixed with nozzles.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention is provided with a separation mechanism. When the projectile is sprayed by the shot blasting machine, the projectile first falls into the bottom groove. Due to gravity, the inclined bottom groove drives the projectile to move to the right. When the projectile passes through the surface of the small square groove with a width smaller than that of the projectile, the small pellet residue will fall from the small square groove to the inside of the waste bin for preliminary separation. The projectile continues to move to the right to the first rectangular opening. The projectile dropped from the first rectangular opening falls on the surface of the circular plate, starting the motor in the motor box to drive the first rotating rod to rotate. The first rotating rod meshes with the gear to drive the second rotating rod to rotate. The second rotating rod drives the circular plate to rotate. The rotating circular plate is slightly tilted inward. The gravity of the projectile and the centrifugal force of the rotation offset each other, causing the projectile to move irregularly on the surface of the circular plate, and large pellet residue remains on the circular plate. The surface of the projectile falls on the top of the screen plate from the second filter hole. The second rotating rod drives the screen plate and drives the pulley assembly at the bottom to rotate on the top of the second support plate. When the rotating pulley assembly moves to the inclined block, it will move upward, thereby pushing the screen plate to rise. When the pulley assembly moves to the top of the inclined block, it suddenly falls, causing the projectile on the surface of the screen plate to suddenly fall and hit the top of the screen plate, thereby causing the pill residue attached to the surface of the projectile to fall off and fall into the first filter hole. Since the projectile is larger than the first filter hole and because of the centrifugal force, the projectile is thrown out from the arc mouth and falls into the inclined arc groove. The inclined inclined arc groove drives the projectile to move to the right due to gravity, and finally is discharged from the discharge pipe, thereby accurately separating the projectile from the pill residue and improving the practicability of the device.

[0015] 2. The present invention is provided with a shot blasting mechanism. When the top of the conveyor belt conveys parts with a large number of angles, the rotating column is rotated to change the angle of the fixed plate. The rotating fixed plate drives the diverter pipes on both sides to rotate. The diverter pipes drive the shot blasting machine to rotate. Multiple shot blasting machines are provided. When the projectiles are fired from the nozzle, the irregular surface of the workpiece is polished, thereby removing dirt, improving the quality of the workpiece, and increasing the practicality of the device.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A shot blasting mechanism 5 is arranged at the top of the inner wall of the top shell 2, and the shot blasting mechanism 5 includes a rotating column 501 rotatably connected to the top of the inner wall of the top shell 2, a fixed plate 502 is fixedly connected to the bottom of the rotating column 501, a shunt pipe 503 is fixedly connected to the bottom of the fixed plate 502, the front end and the rear end of the shunt pipe 503 respectively penetrate the front end and the rear end of the fixed plate 502, the two shunt pipes 503 are connected and fixed at one end away from the fixed plate 502, and the two shot blasting machines 504 are connected and fixed at the bottom. The purpose of setting the rotating column 501 is to rotate the rotating column 501, thereby changing the angle of the shot blasting machine 504 and grinding the irregular surface of the workpiece.

[0036] A specific application of this embodiment is as follows: a separation mechanism 6 is provided. When the shot is sprayed by the shot blasting machine 504, the shot first falls into the bottom groove 104. Due to gravity, the inclined bottom groove 104 drives the shot to move to the right. When the shot passes through the surface of the small square groove 107, which is smaller in width than the shot, the small shot residue will fall from the small square groove 107 to the inside of the waste bin 106 for preliminary separation. The shot continues to move to the right to the first rectangular opening 105. The shot falling out of the first rectangular opening 105 falls on the surface of the circular plate 615, starting the motor in the motor box 602 to drive the first rotating rod 603 to rotate. The first rotating rod 603 engages with the gear 607 to drive the second rotating rod 606 to rotate. The second rotating rod 606 drives the circular plate 615 to rotate. The rotating circular plate 615 tilts slightly inward. The gravity of the shot and the centrifugal force of the rotation offset each other, causing the shot to move irregularly on the surface of the circular plate 615, and large shot residue remains on the circular plate 615. The pellets fall from the second filter hole 616 onto the surface of the screening plate 615, and the pellets fall onto the top of the screening plate 612 from the second filter hole 616. The second rotating rod 606 drives the screening plate 612, and drives the pulley assembly 611 at the bottom to rotate on the top of the second support plate 609. When the rotating pulley assembly 611 moves to the inclined block 610, it moves upward, thereby pushing the screening plate 612 to rise. When the pulley assembly 611 moves to the top of the inclined block 610, it suddenly falls, causing the pellets on the surface of the screening plate 612 to The pellets suddenly fall and hit the top of the screening plate 612, causing the pellet residue attached to the pellet surface to fall off and fall into the first filter hole 614. Since the pellets are larger than the first filter hole 614 and due to centrifugal force, the pellets are thrown out from the arc mouth 613 and fall into the inclined arc groove 618. The inclined inclined arc groove 618 drives the pellets to move to the right due to gravity and is finally discharged from the discharge pipe 619, thereby accurately separating the pellets from the pellet residue and improving the practicability of the device.

[0037] A shot blasting mechanism 5 is provided. When the top of the conveyor belt conveys parts with a surface having many angles, the rotating column 501 is rotated to change the angle of the fixed plate 502. The rotating fixed plate 502 drives the diverter pipes 503 on both sides to rotate. The diverter pipes 503 drive the shot blasting machine 504 to rotate. A plurality of shot blasting machines 504 are provided. When the projectiles are fired from the nozzle 505, the irregular surface of the workpiece is polished, thereby removing dirt, improving the quality of the workpiece, and increasing the practicability of the device.
