Description

Technical Field

[0001] The present application relates to the technical field of seal processing equipment, and in particular to a sandblasting machine for processing mechanical seals. Background Art

[0002] The sandblasting machine uses compressed air as the power, and the sand and air are mixed to form a high-speed jet beam to spray the material along the conveying pipeline at high speed and spray it onto the surface of the workpiece to be processed, so that the attachments on the surface of the workpiece to be processed are peeled off or the mechanical properties of the outer surface are changed.

[0003] "CN219027181U" discloses "a sandblasting machine, comprising a machine body, an operating chamber for sandblasting is arranged in the machine body, an induced draft fan is arranged at the upper end of the machine body... an observation window is arranged on the side wall of the collecting bin". By starting the induced draft fan, the dust generated during operation passes through the dust suction hole, enters the dust suction pipe and is precipitated by the purification component in the precipitation box. Thus, the dust generated during operation is quickly and continuously adsorbed and cleaned, thereby reducing the diffusion of dust in the operating chamber and improving the operating accuracy and sandblasting efficiency of the operator.

[0004] With respect to the above-mentioned related technologies, the inventor believes that when the dust is adsorbed and cleaned by the induced draft fan, some of the tiny dust particles that sink in the dust will adhere to the surface of the workpiece, and some abrasives will also adhere to the surface of the workpiece. When removing the workpiece, not only does it require secondary cleaning of the workpiece, which is time-consuming and labor-intensive, but it is also easy to bring out dust and abrasives, polluting the working environment. Therefore, a sandblasting machine for mechanical seal processing is proposed to solve the above problems.

[0025] A driving motor 15 is fixedly mounted on the inner wall of the dustproof box 7 , and the output shaft end of the driving motor 15 is fixedly connected to one end of the driving shaft 13 .

[0026] One end of the two screw rods 3 passes through the body 1 and is fixedly connected to a rotating wheel 20 . A synchronous belt 21 is commonly installed on the outer walls of the two rotating wheels 20 . A servo motor 22 is fixedly installed on the outer wall of one side of the body 1 . The output shaft of the servo motor 22 is fixedly connected to one rotating wheel 20 .

[0027] A dust hood 18 is installed on the top inner wall of the body 1 , and a suction assembly 16 is fixedly installed on the outer wall of the body 1 . The dust hood 18 is connected to the suction assembly 16 via a connecting pipe 17 .

[0028] A filter plate 10 is fixedly connected to the inner wall of the machine body 1 . The filter plate 10 is located below the plurality of brush plates 9 and directly above the collection bin 2 .

[0029] A sealing door 23 is hingedly connected to the outer wall of the machine body 1 at one side away from the two rotating wheels 20 .

[0030] A plurality of support legs 19 are fixedly connected to the bottom outer wall of the body 1 , and the plurality of support legs 19 are evenly distributed at the four corners of the bottom edge of the body 1 .

[0031] The implementation principle of the sandblasting machine for machining mechanical seals in the embodiment of the present application is as follows: when in use, the sealing door 23 is opened, the workpiece is placed in the inner cavity of the machine body 1, and then the sealing door 23 is closed, and the machine body 1 is started to grind the workpiece. During the grinding process, a large amount of dust is generated in the inner cavity of the machine body 1. At this time, the suction component 16 is started, and the suction component 16 generates suction force in the dust hood 18 through the connecting pipe 17 to suck away most of the dust;

[0032] After the grinding is completed, some dust and abrasives adhere to the surface of the workpiece. Through the cleaning component, the driving motor 15 is started, and the output shaft of the driving motor 15 drives the driving shaft 13 to rotate. When the driving shaft 13 rotates, it drives multiple second bevel gears 14 to rotate, and the multiple first bevel gears 11 meshing with it are driven to rotate through the second bevel gear 14, and the first bevel gear 11 drives the brush plate 9 to rotate and clean through the rotating shaft 8, and then the servo motor 22 is started, and the output shaft of the servo motor 22 drives a rotating wheel 20 to rotate. The two rotating wheels 20 rotate synchronously through the synchronous belt 21, and the rotating wheel 20 drives the two screw rods 3 to rotate synchronously. The two screw rods 3 rotate on the inner wall threads of the two threaded blocks 4, and drive the two threaded blocks 4 to move synchronously along the outer wall of the screw rod 3. At this time, the connecting plate 5 is driven to move through the threaded block 4. The connecting plate 5 starts the hydraulic cylinder 6 during the movement. The hydraulic cylinder 6 can adjust the height of the dustproof box 7 and the multiple brush plates 9 according to the height of the workpiece, so that the connecting plate 5 drives the multiple rotating brush plates 9 to comprehensively clean the workpiece when moving;

[0033] The heavier abrasives swept down fall into the collection bin 2 through the filter plate 10 for collection, while the lighter dust floats in the machine body 1 and is sucked into the suction assembly 16 by the dust hood 18, thus completing the cleaning operation of the workpiece, avoiding the need for secondary cleaning of the workpiece after retrieval, and not polluting the working environment.
