Description

Shot blasting machine

technical field

The invention belongs to the field of shot blasting devices, in particular to a rust-removing shot blasting machine.

Background technique

Shot blasting refers to the mechanical method of projecting the shot material on the working surface at a high speed and a certain angle, so that the shot material impacts the working surface, and then through the airflow cleaning effect of the matching vacuum cleaner inside the machine, the shot material and The cleaned up impurities are recovered separately, and the technology of making the pellets reusable. Compared with other surface treatment technologies, it is faster and more effective. At the same time, the shot blasting machine is used with a dust collector, and the smoke and attachments generated during the working process are uniformly recycled and processed, which is more environmentally friendly.

The shot blasting machine is divided into drum type, chain plate type, rotary type, trolley type, squirrel cage type and hanging type shot blasting machine according to the structure of the casting carrier. Drum type and chain plate type shot blasting machines are suitable for cleaning small and medium-sized castings that are not afraid of collision. The drum type shot blasting machine relies on the spiral guide ribs in the cylinder to make the castings turn over and run forward. The chain plate type shot blasting machine makes the casting turn and run through the movement of the chain plate. Rotary, trolley and hanging shot blasting machines are used to clean large and medium-sized castings, usually with a fixed shot blasting chamber, and the cleaned castings are rotated or moved in the shot blasting chamber. The shot blasting room is generally equipped with several shot blasting machines, which are installed in different positions to project projectiles from different directions to improve the cleaning efficiency and cleaning quality of the shot blasting machine. The hanging shot blasting machine can be equipped with several hooks on the catenary according to the needs of the cleaned castings. When cleaning, the castings are hung on the hooks and turn over by themselves while running forward. Castings are loaded and unloaded outside shot blasting and cleaned indoors.

However, when the existing shot blasting machine is used to remove rust on the surface of the plate, the steel shot is scattered on the ground after impacting the surface of the plate, which is inconvenient for centralized collection, resulting in the problem that the recovery work takes a long time.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a shot blasting machine, so as to solve the problem that the recovery work takes a long time in the prior art.

In order to achieve the above purpose, the basic scheme of the present invention provides a shot blasting machine, which includes a vertical acceleration device, a conveying device for conveying products and a recovery device, the accelerating device is located above the conveying device, and the accelerating device includes a friction plate and an accelerating conveyor belt, The friction plate is made of elastic material. The acceleration conveyor belt is located on one side of the friction plate. The acceleration conveyor belt includes an acceleration belt, a driving roller and a driven roller. The acceleration belt is sleeved on the driving roller and the driven roller. The acceleration belt is parallel to the friction plate. There is an acceleration gap between the acceleration belt and the friction plate, and the recovery device is located on the side of the acceleration device close to the acceleration belt.

The beneficial effects and principles of the basic scheme are: the device can provide the steel shot with a higher impact speed, at the same time improve the rust removal effect of the steel shot, and can well screen the normal steel shot and the worn steel shot, thereby reducing the Time-consuming recycling of steel shot.

When in use, add steel shot into the acceleration gap of the acceleration device, and use the motor to drive the driving roller to rotate, so that the acceleration belt runs at a high speed. Because one side of the steel shot is subjected to the frictional force of the acceleration belt, the rotational speed and the vertical downward moving speed along the friction plate are obtained at the same time. The device accelerated by the acceleration device not only obtains the speed in the vertical direction, but also obtains a higher rotational speed. When the steel shot hits the plate, the surface of the steel ball with a high rotational speed will rub against the surface of the plate for a very short time, so the rust on the surface of the plate can be better removed. At the same time, because the accelerated steel shot rotates in the same direction, the steel shot after colliding with the plate bounces toward the same side of the plate, so it is only necessary to place a recovery groove on one side of the plate to conveniently recover the steel shot. In addition, because the acceleration gap is fixed, the smaller steel shot after wear cannot obtain a higher rotational speed, so the ejection distance is smaller than that of the normal steel shot, that is, the normal steel shot recovery groove is set at a long distance, and the worn steel shot is set at a relatively short distance. Shot recovery tank, which can collect normal steel shot and worn steel shot separately.

Optimization scheme 1: a number of accelerated abrasive particles are fixedly connected to the surface of the acceleration belt. On the one hand, the accelerated abrasive particles loosen the rust on the surface of the steel ball, and on the other hand, increase the friction between the acceleration belt and the steel shot, so that the steel ball can obtain a higher speed.

Optimization scheme 2: A cotton cloth is fixedly connected to the side of the friction plate close to the acceleration belt. The setting of the cotton cloth cleans the rust stains on the steel balls that are loosened by the abrasive particles, and at the same time provides a frictional force opposite to the direction of the acceleration belt movement, so that the worn steel balls can obtain a higher speed and prevent the worn steel balls from contacting the acceleration belt. Unable to obtain rotational speed, deviating from the collection position of worn steel shot.

Optimization plan three: the recovery device includes a recovery tank and a collection tank, the collection tank is located below the friction plate, and the collection tank is located between the conveying device and the recovery tank. The setting of the collection tank and the recovery tank is convenient to separate the normal steel shot and the worn steel shot for recycling.

Optimization scheme four: a feeding device is connected before the acceleration device, and the feeding device is a screw feeder. By controlling the operating speed of the screw feeder, the feeding speed can be better controlled.

Detailed ways

The present invention is described in further detail below by specific embodiments:

Reference numerals in the accompanying drawings include: a conveying device 1 , a friction plate 2 , a feeding device 3 , an acceleration belt 4 , a collection tank 5 , and a recovery tank 6 .

Example: The shot blasting machine in this scheme, as shown in Figures 1 and 2, includes a vertical acceleration device, a conveying device 1 for conveying products, and a recovery device, and the accelerating 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, and the acceleration conveyor belt is located on one side of the friction plate 2 . The acceleration conveyor belt includes an acceleration belt, a driving roller and a driven roller. The acceleration belt is sleeved on the driving roller and the driven roller. The acceleration belt is parallel to the friction plate 2 , and there is an acceleration gap between the acceleration belt and the friction plate 2 . A cotton cloth is fixedly connected to one side of the friction plate 2 close to the acceleration belt, and a number of accelerated abrasive particles are fixedly connected to the surface of the acceleration belt. Baffles are installed on both sides of the acceleration gap to prevent the steel shot from rolling down from the acceleration gap without being accelerated.

The recovery device is located on the side of the acceleration device close to the acceleration belt, and the recovery device includes a recovery tank 6, and the recovery tank 6 is fan-shaped. The device also includes a collection tank 5 , the collection tank 5 is 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.

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 driving roller is driven by the motor to rotate, so that the acceleration belt runs at a high speed. At the limit line of the baffle, the steel shot moves between the acceleration belt and the friction plate. Due to the frictional force of the acceleration belt on one side of the steel shot, the rotational speed and the vertical downward moving speed along the friction plate 2 are obtained at the same time. . The device accelerated by the acceleration device not only obtains the speed in the vertical direction, but also obtains a higher rotational speed. When the steel shot hits the plate, the surface of the steel ball with a high rotational speed will rub against the surface of the plate for a very short time, so the rust on the surface of the plate can be better removed. At the same time, because the accelerated steel shot rotates in the same direction, the steel shot after colliding with the plate bounces toward the same side of the plate, so the steel shot can be easily recovered by placing the recovery groove 6 on one side of the plate. In addition, because the acceleration gap is fixed, the smaller steel shot after wear cannot obtain a higher rotation 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 long distance, and the wear is set at a relatively short distance. The steel shot recovery tank 6 can collect normal steel shot and worn steel shot separately.

The above are only examples of the present invention, and the common knowledge in the solution is not described too much here. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the structure of the present invention.
