The mesh belt conveyor serves to transport the workpiece to be shot blasted.

[0013] (III) Beneficial Effects This utility model provides a mesh belt shot blasting cleaning machine, which has the following beneficial effects: 1. This mesh belt shot blasting machine, through the setup of an air pump, cleaning mechanism, lead screw, and lifting mechanism, allows workpieces to pass through the shot blasting cleaning zone and then be conveyed by a mesh belt to the bottom of the discharge rack. At this point, the air pump starts and delivers high-pressure airflow through air pipes to the inclined air nozzles, spraying the workpiece surface from multiple angles to remove residual shot. For workpieces of different heights, the operator can turn the handwheel to drive the worm gear to rotate, which in turn drives the lead screw to move up and down, causing the cleaning mechanism at the bottom of the support plate to rise and fall as a whole. At the same time, the guide rod ensures smooth movement. After adjusting to the appropriate height, the inclined air nozzles of the cleaning mechanism can be precisely aimed at the workpiece surface to ensure the shot removal effect. Thus, by linking pneumatic cleaning with mechanical lifting, the cleaning efficiency is improved while meeting the processing needs of different workpieces and reducing manual intervention.

[0014] 2. This mesh belt shot blasting machine, through the setting of the feeding rack and baffle mechanism, when stacked workpieces are conveyed by the mesh belt to the area below the feeding rack, multiple sets of inclined baffles guide the workpieces to slide down in an orderly manner in a single layer through their tilt angle, effectively eliminating the internal obstruction caused by stacking. The dispersed workpieces are conveyed to the shot blasting area at a uniform speed by the mesh belt, ensuring that the surface of each workpiece is in uniform contact with the shot blasting medium and avoiding cleaning dead corners. The arc groove design of the side support allows for the adjustment of the inclined baffle angle, which is convenient for adjusting the baffle angle according to the workpiece size or friction coefficient. Thus, through the linkage mechanism of mechanical adjustment and physical dispersion, the problem of uneven cleaning of stacked workpieces is effectively solved, while also adapting to the needs of diverse workpieces, significantly improving the versatility of the equipment.

The adjustment door 10 facilitates the adjustment of the inclined baffle 401. The air pipe 601 is connected to the top of the discharge rack 3 and is fixedly connected to the bottom of the support plate 803. The support plate 803 is used to drive the air pipe 601 to move up and down. A protective cover 11 is threaded onto the top of the discharge rack 3. A lead screw 7 is threaded through and connected to the top of the protective cover 11. Bearings A12 are sleeved on both sides of the worm gear 802. The two sets of bearings A12 are fixedly connected to the inner wall of the protective cover 11. The protective cover 11 serves to protect the internal structure of the protective cover 11. Bearings B13 are sleeved on both sides of the worm wheel 801. One set of bearings B13 is fixedly connected to the top of the discharge rack 3.

The second step: When the stacked workpieces are conveyed by the mesh belt to the feed rack 2, multiple sets of inclined baffles 401 guide the workpieces to slide down in an orderly manner in a single layer through their tilt angle, effectively eliminating the internal obstruction caused by stacking. The dispersed workpieces are conveyed to the shot blasting area at a uniform speed by the mesh belt, ensuring that the surface of each workpiece is in uniform contact with the shot blasting medium and avoiding cleaning dead corners. The arc groove design of the side support 402 allows the tilt angle of the inclined baffles 401 to be adjusted, which is convenient to adjust the baffle tilt angle according to the workpiece size or friction coefficient.
