Description

Technical Field

[0001] The present application relates to the technical field of sandblasting, and in particular to a sandblasting machine booster device. Background Art

[0002] Sandblasting machine is a kind of equipment used for surface treatment, which mainly cleans or changes the surface of objects by spraying abrasives at high speed. In order to improve the spraying power and efficiency of abrasives during sandblasting, ensure sufficient air volume and air pressure to maintain uniform flow of abrasives, and overcome friction loss and resistance in the pipeline, a sandblasting machine booster device is needed.

[0003] During use, the existing sandblasting machine booster device often provides insufficient pressure to meet the needs of the sandblasting operation, resulting in the sandblasting effect far from the expected standard. If the pressure is insufficient, the sand particles cannot be sprayed onto the surface to be treated with sufficient speed and force. In this way, not only can the dirt, rust or other attachments on the surface not be effectively removed, but the treated surface may also be uneven and even damage the material itself. In addition, insufficient pressure will directly affect the efficiency of cleaning or grinding, so that the operation that could have been completed in a shorter time will take longer to achieve the same treatment effect, affecting the overall efficiency of the production line.

[0004] Therefore, in order to solve the above problems, the present application provides a sandblasting machine booster device.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0021] The compression part 3 includes a pressure plate 301, a piston rod 302 and a mounting block 303, wherein the piston rod 302 movably penetrates the rear side wall of the tank body 1 and is fixedly connected to the pressure plate 301, and the rear end of the piston rod 302 is fixedly connected to the connecting rod 7 through the mounting block 303, and the pressure plate 301 is movably arranged in the tank body 1.

[0022] The open end of the elastic sealing sleeve 2 is fixedly connected to the inner wall of the tank body 1 , and the other end of the elastic sealing sleeve 2 is fixedly connected to the pressing plate 301 . A spring 4 is fixedly installed on the side of the pressing plate 301 away from the elastic sealing sleeve 2 , and the spring 4 is located inside the tank body 1 .

[0023] The pressure control unit 5 includes an air supply pump 501 and a pressure relief pump 502 , wherein the air supply pump 501 and the pressure relief pump 502 are both fixedly installed on the rear side wall of the tank body 1 .

[0024] The discharge part 8 includes a motor 801, a connector 802 and a sealing plug 803, wherein the output shaft of the motor 801 is fixedly mounted with the connector 802, the end of the connector 802 is connected with the sealing plug 803, and the sealing plug 803 is movably sealed at the discharge port at the front of the tank body 1.

[0025] The feed pipe 9 is connected with a sand replenishing machine.

[0026] A sand collecting chamber is formed between the front side of the pressing plate 301 and the tank body 1 , and an air collecting chamber is formed between the rear side of the pressing plate 301 and the tank body 1 .

[0027] The implementation principle of a sandblasting machine booster device in the embodiment of the present application is:

[0028] Refilling: The pressure of the tank body 1 is relieved by the pressure relief pump 502, so that the air in the air collecting chamber between the pressure plate 301 and the inner cavity of the tank body 1 is gradually extracted, and negative pressure is formed in the air chamber. Under the elastic potential energy of the spring 4, the piston rod 302 and the pressure plate 301 drive the elastic sealing sleeve 2 connected thereto to move backward and stretch. At the same time, the sand collecting chamber where the elastic sealing sleeve 2 is located is expanded, and the pressure is reduced. Then, the sand in the sand replenishing machine is automatically replenished into the sand collecting chamber through the feeding pipe 9. In the process of the piston rod 302 moving backward, the mounting block 303 drives the discharge part 8 to move backward together through the connecting rod 7 until the sealing plug 803 covers the discharge port of the tank body 1.

[0029] Spraying: The tank body 1 is pressurized by the air supply pump 501, so that the outside air enters the pressure plate 301 and the air collecting cavity in the tank body 1, forming a high-pressure airflow. The high-pressure airflow pushes the pressure plate 301, the mounting block 303 and the connecting rod 7 forward together. At the same time, the volume of the sand collecting cavity where the elastic sealing sleeve 2 is located is reduced, and then the sand is discharged through the discharge port, thereby enhancing the cleaning or grinding effect;

[0030] When the connecting rod 7 moves forward, the output shaft of the motor 801 drives the sealing plug 803 to flip through the connecting piece 802, so that the sealing plug 803 is separated from the discharge port of the tank body 1 to avoid affecting the sandblasting trajectory.
