Shot blasting machine

[0017] Example: The shot blasting machine in this scheme, such as figure 1 with figure 2 As shown, it includes a vertical acceleration device, a product conveying device 1 and a recycling device, and the acceleration device is located above the conveying device 1. The acceleration device includes a friction plate 2 and an acceleration conveyor belt. The friction plate 2 is made of elastic materials such as rubber or nylon. The acceleration conveyor belt is located on one side of the friction plate 2. The accelerating conveyor belt includes an accelerating belt, a driving roller and a driven roller. The accelerating belt is sleeved on the driving roller and the driven roller. The accelerating belt is parallel to the friction plate 2, and there is an accelerating gap between the accelerating belt and the friction plate 2. The friction plate 2 is fixedly connected with cotton cloth on one side close to the acceleration belt, and a number of acceleration abrasive particles are fixedly connected on the surface of the acceleration belt. Baffles are installed on both sides of the acceleration gap to prevent steel shots from rolling down from the acceleration gap and not being accelerated.

[0018] The recovery device is located on the side of the acceleration device close to the acceleration belt. The recovery device includes a recovery tank 6 which is fan-shaped. The device also includes a collection tank 5 located below the friction plate 2, and the collection tank 5 is located between the conveying device 1 and the recovery tank 6. A feeding device 3 is connected before the acceleration device, and the feeding device 3 selects a screw feeder.

[0019] When in use, the steel shot is added to the feeding device 3, and the steel shot is added to the acceleration gap of the acceleration device through the feeding device 3, and the motor is used to drive the driving roller to rotate to make the acceleration belt run at high speed. At the limit line of the baffle, the steel shot moves between the acceleration belt and the friction plate. Because one side of the steel shot is subjected to the friction force of the acceleration belt, the speed and the vertical downward movement speed along the friction plate 2 are obtained at the same time. . The device accelerated by the acceleration device not only obtains the vertical speed, but also obtains a higher rotation speed. When the steel shot hits the plate, the steel ball with a higher speed will cause the surface of the steel ball to rub against the surface of the plate for a short time, so the rust on the surface of the plate can be better removed. At the same time, because the accelerated steel shots rotate in the same direction, the steel shots that collide with the plate bounce toward the same side of the plate. Therefore, the steel shot can be recovered conveniently by placing the recovery slot 6 on one side of the plate. In addition, because the acceleration gap is fixed, the smaller steel shot after abrasion cannot obtain a higher speed, so the ejection distance is smaller than that of the normal steel shot, that is, the normal steel shot recovery groove 6 is set at a longer distance, and the wear is set at a closer distance. The steel shot recovery tank 6 can separate normal steel shots and worn steel shots.
