Technical Field
[0001] This utility model relates to the field of shot blasting machine technology, specifically a shot blasting machine feeding device. Background Technology
[0002] A shot blasting machine is a device that uses a high-speed rotating impeller to propel shot onto the surface of a workpiece, thereby cleaning the workpiece. The main function of the feeding device is to deliver the workpiece or material to be cleaned into the working area of the shot blasting machine for subsequent shot blasting treatment.
[0003] The feeding device of a shot blasting machine is a crucial component for ensuring continuous and stable workpiece input. A well-designed material conveying, distribution, and control mechanism ensures that the shot blasting machine can efficiently and accurately complete its cleaning tasks.
[0004] In traditional shot blasting machines, the feeding device often struggles to adapt to materials of different sizes, causing the material to easily shift or get stuck during the feeding process, which in turn affects the uniformity and efficiency of shot blasting. Therefore, a new feeding device for shot blasting machines is proposed to address the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, in traditional shot blasting machines, the feeding device often struggles to adapt to materials of different sizes, leading to material deviation or jamming during the feeding process, which in turn affects the uniformity and efficiency of shot blasting. This utility model proposes a feeding device for shot blasting machines.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A shot blasting machine feeding device of this utility model includes a shot blasting machine body; a support base is fixedly installed inside the shot blasting machine body, both ends of which penetrate the shot blasting machine body and extend to its exterior; multiple support rollers are rotatably mounted in parallel inside the support base; a movable bracket is slidably mounted on the feeding end of the support base; a threaded hole is opened on one side of the upper part of the movable bracket; gearboxes are fixedly installed on both sides of the upper part of the feeding end of the support base; a lead screw is provided on the side of the gearbox near the shot blasting machine body; one end of the lead screw is rotatably mounted inside the gearbox and fixedly mounted with a first bevel gear, and the other end is rotatably mounted on the upper part of the support base; the lower ends of the movable bracket are slidably mounted on both sides of the lead screw. Above, a fixed bracket is horizontally and fixedly installed on the outer side of the upper end of the movable bracket. A through hole is opened at the center of the front end of the fixed bracket, and a sliding groove is provided at the upper end of the through hole and fixedly installed on the upper part of the fixed bracket. A sliding rod is slidably installed inside the sliding groove. Multiple toothed grooves are arrayed on one side of the sliding rod. The lower end of the sliding rod passes through the support frame and is fixedly installed with an adjustment box. Clamping plates are slidably installed in both ends of the adjustment box. Cylinders are fixedly installed in both ends of the adjustment box. The piston rods of the cylinders are located inside the adjustment box and are fixedly connected to the clamping plates. Driven by the lead screw and gearbox, the movable bracket can be flexibly adjusted. The feeding position can be adjusted according to the material size. Through the cooperation of the sliding rod, adjustment box and cylinders, the clamping plates can be adaptively opened and closed, ensuring the stability and safety of the material during the feeding process.
[0007] Preferably, a first motor is fixedly installed on one side of the discharge end of the support base. The rotating shaft of the first motor is fixedly connected to one end of the support roller. A groove is opened on the other side of the support base. A transmission gear is fixedly installed on one end of the support roller located in the groove. The transmission gears rotate in cooperation with each other through a transmission belt. By setting the drive of the support base and the support roller, the stable transmission of material on the support roller is realized, which solves the problem of material deviation or jamming in traditional shot blasting machines and improves the uniformity and efficiency of shot blasting.
[0008] Preferably, a connecting rod is inclinedly arranged between the movable support and the fixed support on both sides. One end of the connecting rod is fixedly connected to the outer side of the upper end of the movable support, and the other end is fixedly connected to the center of the upper side of the fixed support. The connection of the connecting rod enhances the structural stability between the movable support and the fixed support, making the entire feeding device more stable and reliable.
[0009] Preferably, a second motor is fixedly mounted on a fixed bracket on one side of the slide rail, and a drive gear is fixedly mounted on the rotating shaft of the second motor. The teeth on the drive gear mesh with the grooves on the slide rod. Through the cooperation of the second motor and the drive gear, the lifting and lowering adjustment of the clamping plate is realized, so that the feeding device can flexibly adapt to materials of different heights and improve the stability and accuracy of clamping.
[0010] Preferably, a third motor is fixedly installed on the outside of each gearbox, and the rotating shaft of each third motor is located inside the gearbox and a second bevel gear is fixedly installed thereon. The second bevel gear is perpendicular to and meshes with the first bevel gear. Through the cooperation of the third motor and the bevel gear transmission mechanism, the precise movement of the movable support on the support base is realized.
[0011] Preferably, each of the movable brackets has an installation groove on one side of the lower end of the support base. A roller is rotatably installed in the installation groove via a rotating shaft. The roller fits against the upper part and the bottom of the support base. By setting the roller, not only is the frictional resistance reduced, but the impact force of the movable bracket during the sliding process is also dispersed by the rolling action, thereby enhancing the stability and durability of the movable bracket.
[0012] The advantages of this utility model are:
[0013] 1. This utility model, during the shot blasting process, involves a third motor driving a second bevel gear to rotate during material feeding. Simultaneously, the first bevel gear drives a lead screw to rotate, causing a movable bracket to slide on a support base. A fixed bracket moves an adjusting box above the material. The second motor then drives a drive gear to rotate, causing a sliding rod to slide down a groove, moving clamping plates to both sides of the material. A cylinder pushes the clamping plates to move relative to each other within the adjusting box, clamping and fixing the material. The second motor then lifts the material above the support base. The third motor drives a lead screw to move the movable bracket towards the shot blasting machine body. The material is then placed on top of the support rollers. The first motor then drives the support rollers to rotate, simultaneously driving all support rollers to rotate with the cooperation of transmission gears and belts. This structural design moves the material into the shot blasting machine body for cleaning and then removes it. This design achieves flexibility and stability in material feeding, solving the problem in traditional shot blasting machines where the feeding device often cannot adapt to materials of different sizes, leading to material deviation or jamming during feeding, thus affecting the uniformity and efficiency of shot blasting. This design improves the efficiency and uniformity of shot blasting. Attached Figure Description

[0022] Please see Figure 1-5As shown, a shot blasting machine feeding device includes a shot blasting machine body 1; a support base 2 is fixedly installed inside the shot blasting machine body 1, with both ends of the support base 2 penetrating through the shot blasting machine body 1 and extending to its exterior; multiple support rollers 3 are rotatably mounted in parallel inside the support base 2; a movable bracket 7 is slidably installed on the feeding end of the support base 2; the movable bracket 7 has a threaded hole on one side of the upper part of the support base 2; gearboxes 18 are fixedly installed on both sides of the upper part of the feeding end of the support base 2; each gearbox 18 has a lead screw 17 on the side near the shot blasting machine body 1; the lead screw 17... One end of the movable bracket 7 is rotatably mounted inside the gearbox 18 and fixedly mounted with a first bevel gear 19. The other end is rotatably mounted on the upper part of the support base 2. Both sides of the lower end of the movable bracket 7 are slidably mounted on the lead screw 17. A fixed bracket 8 is horizontally and fixedly mounted on the outer side of the upper end of the movable bracket 7. A through hole is opened at the center of the front end of the fixed bracket 8. A sliding groove 10 is provided at the upper end of the through hole and fixedly mounted on the upper part of the fixed bracket 8. A sliding rod 11 is slidably mounted inside the sliding groove 10. Multiple toothed grooves are arrayed on one side of the sliding rod 11. The lower end of the sliding rod 11 passes through the support frame and is fixedly mounted with an adjusting box 14. Both ends of the regulating box 14 are slidably mounted with clamping plates 15, and both ends of the regulating box 14 are fixedly mounted with cylinders 16. The piston rods of the cylinders 16 are located inside the regulating box 14 and are fixedly connected to the clamping plates 15. During operation, when the material is fed during shot blasting, the third motor 20 is started to drive the second bevel gear 21 to rotate, and at the same time, the first bevel gear 19 drives the lead screw 17 to rotate, causing the moving bracket 7 to slide on the support seat 2. Simultaneously, the fixed bracket 8 drives the regulating box 14 to move above the material, and the second motor 12 is started to drive the drive gear 13 to rotate, driving the sliding bracket 7 to slide on the support seat 2. Rod 11 slides down in chute 10, causing clamping plate 15 to move to both sides of the material. Cylinder 16 is activated to push clamping plate 15 to move relative to material in adjustment box 14, clamping and fixing material. Then, second motor 12 lifts material above support seat 2. Third motor 20 drives screw 17 to move moving bracket 7 towards shot blasting machine body 1. Then, material is placed on support roller 3. First motor 4 is activated to drive support roller 3 to rotate. At the same time, with the cooperation of transmission gear 5 and transmission belt 6, all support rollers 3 are driven to rotate, driving material to move into shot blasting machine body 1 for cleaning and then removing it.
[0023] A first motor 4 is fixedly installed on one side of the discharge end of the support base 2. The rotating shaft of the first motor 4 is fixedly connected to one end of the support roller 3. A groove is opened on the other side of the support base 2. A transmission gear 5 is fixedly installed on one end of the support roller 3 located in the groove. The transmission gears 5 rotate in cooperation with each other through a transmission belt 6. During operation, when the material is fed during the shot blasting process, the first motor 4 is started. The first motor 4 drives the support roller 3 to rotate synchronously.

One end of the connecting rod 9 is fixedly connected to the outer side of the upper end of the movable support 7, and the other end is fixedly connected to the center of the upper side of the fixed support 8. During operation, when the material is fed during shot blasting, when the movable support 7 slides along the support seat 2 under the drive of the lead screw 17, the connecting rod 9 can effectively prevent the movable support 7 from shaking or tilting, thereby enhancing the structural stability of the entire feeding device.
[0025] A second motor 12 is fixedly mounted on a fixed bracket 8 on one side of the slide 10. A drive gear 13 is fixedly mounted on the rotating shaft of the second motor 12. The teeth of the drive gear 13 mesh with the grooves of the slide rod 11. During operation, when feeding materials during shot blasting, the second motor 12 is started to drive the drive gear 13 to rotate.

[0026] A third motor 20 is fixedly installed on the outside of each gearbox 18. The rotating shaft of each third motor 20 is located inside the gearbox 18 and a second bevel gear 21 is fixedly installed thereon. The second bevel gear 21 and the first bevel gear 19 are perpendicular to each other and mesh with each other. During operation, when feeding materials during shot blasting, if the feeding position needs to be adjusted, the third motor 20 is started. Its rotating shaft will drive the second bevel gear 21 to rotate, which in turn drives the first bevel gear 19 and the lead screw 17 to rotate. The rotation of the lead screw 17 will be converted into the linear movement of the moving bracket 7, thereby realizing the precise adjustment of the feeding position.
[0027] The movable bracket 7 is provided with a mounting groove on one side of the lower end of the support base 2. A roller 22 is rotatably mounted in the mounting groove via a rotating shaft. The roller 22 fits against the upper part and the bottom of the support base 2. During operation, when the material is fed during shot blasting, the roller 22 can reduce frictional resistance and improve the smoothness and stability of the sliding when the movable bracket 7 slides along the support base 2 under the drive of the lead screw 17.
[0028] The working principle is as follows: When feeding materials during shot blasting, the third motor 20 drives the second bevel gear 21 to rotate, while the first bevel gear 19 drives the lead screw 17 to rotate, causing the moving bracket 7 to slide on the support base 2. At the same time, the fixed bracket 8 moves the adjusting box 14 above the material. The second motor 12 drives the drive gear 13 to rotate, causing the slide rod 11 to slide down in the slide groove 10, moving the clamping plate 15 to both sides of the material. The cylinder 16 is activated to push the clamping plate 15 to move relative to each other in the adjusting box 14, clamping and fixing the material. Then, the second motor 12 lifts the material above the support base 2. The third motor 20 drives the lead screw 17 to drive the moving bracket 7 to move towards the shot blasting machine body 1. Then, the material is placed on the support roller 3. The first motor 4 drives the support roller 3 to rotate, and at the same time, with the cooperation of the transmission gear 5 and the transmission belt 6, all the support rollers 3 rotate, driving the material to move into the shot blasting machine body 1 for cleaning and then removing it.
