A sandblasting workpiece cleaning device is characterized in that it includes a circular rotary box with a material inlet and a material outlet, and the rotary box is placed at an inclination, one side of the material inlet is higher, and the side of the material outlet is lower. There are bearing seats on both sides of the box, and the bearing seats are fixed on the bracket. There are bearings in the bearing seats to connect with the transmission box. The outside of the transmission box is connected to the motor. The square box is fixed on the bracket, and the outside of the square box is equipped with a high-pressure air nozzle. The high-pressure air nozzle communicates with the air compressor through the air pipe. The inner wall of the box is provided with a symmetrical fixed plate, and fine steel wires are fixed on the fixed plate, and a collecting box is arranged under the square box, and a filter screen is arranged above the collecting box.

As an improvement of the present invention, the impact platform is a rubber impact platform.

As an improvement of the present invention, the inside of the rotary box is a rubber layer or a plastic layer.

As an improvement of the present invention, the air pipe is provided with a control valve.

As an improvement of the present invention, the inclination angle of the rotary box is 15-20°.

As an improvement of the present invention, there are two high-pressure gas nozzles arranged symmetrically.

As an improvement of the present invention, the filter screen is a stainless steel filter screen with a mesh size of 0.5-2 mm.

As an improvement of the present invention, the impact platform is trapezoidal or semicircular.

The beneficial effects of the present invention are:

The sandblasting workpiece cleaning device described in the present invention has simple structure, is convenient and practical, and does not need manual cleaning. The workpiece is first rotated and impacted to remove sand, and then the surface is blown clean with compressed air, and finally the workpiece is dropped by a group of fine steel wires. All the sand stuck on the surface will be removed, and the sand cleaning effect is good.

Detailed ways

The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

As shown in the figure, a sandblasting workpiece cleaning device according to the present invention includes a circular rotary box 1 with a feed port 2 and a discharge port 3. The rotary box 1 is placed at an angle, and the feed port 2- The side is high, the side of the discharge port 3 is low, and the two sides of the rotary box 1 are provided with bearing seats 4, and the bearing seats 4 are fixed on the bracket 5. There are bearings in the bearing seats 4 connected to the transmission box 8, and the outside of the transmission box 8 is connected to the motor 9 , the inner wall of the rotary box 1 is staggeredly fixed with an impact table 6, and the bottom of the discharge port 3 is provided with a square box 16 with upper and lower openings. The nozzle 15 communicates with the air compressor 12 through the trachea 11. The front end of the high-pressure air nozzle 15 passes through the square box 16 to blow air in the opposite box. The inner wall of the square box below the high-pressure air nozzle 15 is provided with a symmetrical fixed plate 17. Thin steel wire 18, be provided with collecting box 14 below square box 16, be filter screen 13 above collecting box 14.

When working, the workpiece is put in from the feed port, and the rotary box rotates. Since the inner wall of the rotary box 1 is staggered and fixed with impact tables 6, the impact tables 6 can be set in a trapezoidal or semicircular shape, and the workpiece is continuously impacted in the rotary box. , the sand is knocked down, because the rotary box 1 is placed at an inclination, the workpiece hits and rolls in the rotary box, and continues downward under the action of its own gravity, and finally the workpiece and the fallen sand all gather at the discharge port, and the discharge port is opened , all fall into the filter net from the square box, blow the surface clean with compressed air first, and finally fall through the extrusion of the thin steel wire group, which can remove all the sand stuck on the surface of the workpiece, and the sand cleaning effect is good.

In order to protect the surface of the workpiece from being bruised, the present invention sets the impact table 6 as a rubber impact table to protect the workpiece. In order to better protect the surface of the workpiece, the inside of the rotary box 1 is all set as a rubber layer or a plastic layer 7, that is The surface of the workpiece is protected, and the sound of the workpiece hitting the inner wall when rolling is reduced.

The present invention is provided with control valve 10 on described air pipe 11, can close compressed air at any time.

The present invention not only needs to consider the power and time for the workpiece to roll in the rotary box, but also needs to consider allowing the workpiece to be smoothly gathered at the discharge port. After testing, the tilt angle of the rotary box 1 is 15-20°, which can take into account both aspects , where the inclination angle of 17° works best.

In order to clean the surface with compressed air when the workpiece falls, there are 2 or 4 high-pressure air nozzles 15 in the present invention, which are arranged symmetrically and have a good sand blowing effect.

The filter screen 13 of the present invention is a stainless steel filter screen with a mesh size of 0.5-2mm.

The technical means disclosed in the solutions of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
