Description

Technical Field

[0001] This utility model relates to the field of steel shot production technology, and in particular to a shot collection device for a shot cutter. Background Technology

[0002] In a stainless steel shot production line, the core function of the shot collection device is to recover and initially screen irregularly shaped shot after cutting, ensuring production continuity and improving finished product quality. This device receives the stainless steel wire segments (initial shot) produced by the cutting machine in a closed system, preventing splashing and spillage that could lead to raw material loss or equipment wear. Simultaneously, a directional conveying mechanism transfers the shot to the spherical polishing process, reducing exposure time and preventing oxidation (stainless steel is prone to oxidation at high temperatures, affecting final performance). Furthermore, its continuous collection function significantly shortens the shot's residence time at the cutting station, avoiding the risk of entanglement or deformation due to accumulation, laying the foundation for subsequent spherical polishing to form uniform spherical particles. Finally, through precise flow control, the device ensures synchronized production line rhythm, improving overall efficiency and the yield and consistency of stainless steel shot.

[0003] The existing pellet collection device for shot cutting machines has two shortcomings: first, it cannot achieve efficient recycling and initial screening of the cut pellets; second, it cannot achieve rapid transfer of the pellets to the spherical polishing process.

[0004] In view of this, the inventors hope to optimize and improve the existing pellet collection device for pellet cutting machines. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a pellet collection device for pellet cutting machines.

[0023] In this embodiment, the stepped screening hole 103 has a structure that is wider on the outside and narrower on the inside. The filter hole size of the filter plate is larger than the outer opening size of the stepped screening hole 103. The filter plate is used to intercept large-diameter pellets, and the screening roller 10 is used to screen out small-diameter pellets.

[0027] The working principle of this embodiment is as follows: Shot collection: The stainless steel wire segments (initial shot) produced by the cutting machine fall into the collection hopper 3, where the collection hopper 3 performs initial collection of the shot.

[0028] Primary screening of large-diameter shot: Large-diameter shot enters the shaking screen box 506 through the feeding pipe 507. Shaking the push rod 508 extends and retracts the movable end, causing the shaking screen box 506 to slide back and forth on the slide rail 504, thus achieving the shaking screen action. The large-diameter shot is intercepted by the removable and cleanable filter plate at the bottom of the shaking screen box 506 and remains inside the shaking screen box 506, achieving the initial screening of the large-diameter shot. The beam plate 501 slides on the pusher 4 via the sliding sleeves 502 at both ends and is locked in position by the fastening handle 503.

The circular roller 101 of the screening roller 10 has several stepped screening holes 103 that communicate with the internal adsorption chamber 102 in the circumferential direction. The stepped screening holes 103 have a structure that is wider on the outside and narrower on the inside. During the flipping process, small-diameter shot enters the adsorption chamber 102 through the stepped screening holes 103.

[0030] Small-diameter pellet removal: The negative pressure fan 14 of the small-diameter pellet removal component is working. Its suction end is connected to the convex tube 105 of the screening roller 10 through the suction bend 13. The small-diameter pellets in the adsorption chamber 102 are drawn into the negative pressure fan 14 through the suction bend 13. The collection filter bag installed inside the negative pressure fan 14 collects and intercepts the small-diameter pellets.

[0031] Transfer of qualified shot: After passing through the large-diameter primary screening and small-diameter screening, the qualified shot enters the screw conveyor 9 through the feed pipe 8. The screw conveyor 9 quickly transports the qualified shot to the rounding process, ensuring the production line rhythm is synchronized and improving the overall efficiency and the yield and consistency of stainless steel shot.
