Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a separator screen structure for shot blasting machines. Background Technology

[0002] Shot blasting equipment is widely used in industries such as casting, forging, and machinery manufacturing to remove impurities such as oxide scale, adhering sand, and welding slag from the surfaces of castings, forgings, and structural parts. Its working principle involves using high-speed steel shot propelled by a shot blaster to impact the workpiece surface, thereby achieving cleaning and strengthening. After use, the steel shot mixes with the removed impurities. This mixture needs to be recycled through a separation device to separate reusable, qualified steel shot from the waste, ensuring the efficiency and cleaning quality of the shot blasting process. However, existing shot blasting machine separator screen structures still have the problem of not being able to remove impurities adhering to the steel shot by rubbing its surface, easily causing dust and impurities to fly around during separation.

[0003] Therefore, it is essential to invent a new screen structure for a shot blasting machine separator. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a shot blasting machine separator screen structure. This solves the problem that existing shot blasting machine separator screen structures still cannot remove impurities adhering to the steel shot surface through rubbing, leading to dust and impurities flying around during separation. The shot blasting machine separator screen structure includes a support frame, drive shafts, a rubbing surface, a steel shot separation plate, an impurity storage box, and mounting support legs. The drive shafts are rotatably mounted at both ends inside the support frame, and the rubbing surface wraps around the outside of the two sets of drive shafts. The steel shot separation plate is slidably mounted inside the support frame. The steel shot separation plate is located below the rubbing surface, and the impurity storage box is fixedly mounted at the bottom of the support frame. The mounting support legs are fixedly mounted at the four corners of the bottom of the support frame.

[0005] The rubbing surface includes a support layer, a reinforcing layer, a reinforcing rib, a buffer layer, and a rubbing groove. The reinforcing layer is fixedly installed inside the support layer, and the reinforcing rib is fixedly installed inside the reinforcing layer. The buffer layer is fixedly installed outside the support layer, and the rubbing groove is provided on the outer surface of the buffer layer.

[0006] The steel shot separation plate includes a supporting outer frame, a receiving plate, a limiting plate, and a separating mesh. The receiving plate is fixedly installed at the feed end of the supporting outer frame, and the limiting plate is fixedly installed on both sides of the surface of the receiving plate. The separating mesh is fixedly installed inside the supporting outer frame.

[0007] The rubbing surface and two sets of drive shafts together form a conveyor belt structure, and the rubbing surface can rotate by the drive shaft. The rubbing surface can rub the steel shot on the surface of the steel shot separation plate and move it forward. The buffer layer inside the rubbing surface can undergo slight deformation after contacting the steel shot, and the rubbing groove adopts several parallel grooves. The size of the rubbing groove matches the steel shot.

[0008] The steel shot separation plate is a rectangular steel metal structure with the receiving plate and limiting plate exposed to receive steel shot and impurities falling from above. One end of the limiting plate is provided with a groove whose curvature matches the transmission axis. Steel shot that moves forward by being rubbed by the rubbing surface continuously rolls on the surface of the separation mesh. Impurities that fall through the separation mesh can enter the interior of the impurity storage box.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. The rubbing surface of this utility model is driven to rotate by a transmission shaft. The rubbing grooves on the surface continuously rub the steel shot on the steel shot separation plate, causing it to roll and move forward evenly on the separation mesh. This process can effectively disperse the mixture and promote impurities to fall into the impurity storage box through the separation mesh. It also uses the internal buffer layer to make flexible contact to reduce the wear of the steel shot, thereby significantly improving the separation efficiency and extending the service life of the steel shot.

[0010] 2. The steel shot separation plate of this utility model is set up to screen the steel shot through a separation mesh fixedly installed on its surface; the receiving plate at the feeding end is responsible for receiving the material, and the limiting plates on both sides prevent the steel shot from scattering during rolling. Finally, qualified steel shot is moved along the surface of the separation mesh under the drive of the rubbing surface to achieve recycling, while fine impurities fall into the impurity storage box below through the separation mesh, thus completing efficient separation.

The drive shaft 2 is rotatably mounted at both ends inside the support frame 1, and the rubbing surface 3 wraps around the outer sides of the two sets of drive shafts 2. The shot separation plate 4 is slidably mounted inside the support frame 1. The shot separation plate 4 is located below the rubbing surface 3, and the impurity storage box 5 is fixedly mounted at the bottom of the support frame 1. The mounting support legs 6 are fixedly mounted at the four corners of the bottom of the support frame 1.

[0018] The rubbing surface 3 includes a support layer 31, a reinforcing layer 32, a reinforcing rib 33, a buffer layer 34, and a rubbing groove 35. The reinforcing layer 32 is fixedly installed on the inner side of the support layer 31, and the reinforcing rib 33 is fixedly installed inside the reinforcing layer 32. The buffer layer 34 is fixedly installed on the outer side of the support layer 31, and the rubbing groove 35 is provided on the outer surface of the buffer layer 34.

[0019] The steel shot separating plate 4 includes a supporting outer frame 41, a receiving plate 42, a limiting plate 43, and a separating mesh 44. The receiving plate 42 is fixedly installed at the feeding end of the supporting outer frame 41, and the limiting plate 43 is fixedly installed on both sides of the surface of the receiving plate 42. The separating mesh 44 is fixedly installed inside the supporting outer frame 41.

[0020] The rubbing surface 3 and the two sets of drive shafts 2 together form a conveyor belt structure, and the rubbing surface 3 can rotate by the drive shaft 2. The rubbing surface 3 can rub the steel shot on the surface of the steel shot separation plate 4 and move it forward. The buffer layer 34 inside the rubbing surface 3 can undergo slight deformation after contacting the steel shot, and the rubbing groove 35 adopts several parallel grooves. The size of the rubbing groove 35 matches the steel shot.

[0021] The steel shot separating plate 4 is a rectangular steel metal structure, with the receiving plate 42 and the limiting plate 43 exposed to receive steel shot and impurities falling from above. One end of the limiting plate 43 is provided with a groove whose arc matches that of the drive shaft 2. The surface of the separating mesh 44 is continuously covered with steel shot that is rubbed forward by the rubbing surface 3. Impurities that fall through the separating mesh 44 can enter the interior of the impurity storage box 5.

[0022] The separator screen structure of this shot blasting machine is mainly supported by a support frame 1 and mounting support legs 6. Its core working principle begins with the mixed material falling into the receiving plate 42 of the steel shot separation plate 4. The rubbing surface 3, driven by the transmission shaft 2, continuously rubs the steel shot through the surface rubbing groove 35, causing the steel shot to roll forward on the surface of the separation screen 44.

[0023] During the rolling process, the buffer layer 34 flexibly contacts and reduces steel shot wear, while the separating mesh 44 efficiently screens impurities: qualified steel shot is retained and recycled, while fine impurities fall through the mesh into the bottom impurity storage box 5. The limiting plate 43 prevents steel shot from scattering, and the reinforcing layer 32 and reinforcing ribs 33 ensure the structural strength of the rubbing surface 3, ultimately achieving automated and efficient separation of steel shot and impurities.
