Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a shot blasting machine with a dustproof structure. Background Art

[0002] Shot blasting machine is a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The shot blasting machine can simultaneously remove sand, core and clean castings. The process of spraying steel or glass shots onto parts with compressed air to remove scale and other dirt is called shot blasting. Steel shots can also be sent to a high-speed rotating disc, and the centrifugal force is used to make the high-speed thrown steel shots hit the surface of the parts to achieve the purpose of finishing. This process is called shot blasting. During the operation, the shot blasting machine will generate a certain amount of dust when it hits the workpiece, and a certain amount of dust will also adhere to the shot material, resulting in a lot of dust in the shot blasting machine. However, most of the existing shot blasting machine structures cannot remove the internal dust during use, and cannot clean the dust on the surface of the shot material, so it is necessary to improve the existing structure.

[0003] In order to solve the above problems, a shot blasting machine with a dustproof structure disclosed in the patent document with the publication (announcement) number: CN217801104U includes: a shell, shot blasting heads are arranged on both sides of the shell, a hanger is arranged in the shell, a baffle is rotatably installed on one side of the top opening of the shell, a hydraulic cylinder is arranged between the baffle and the mounting frame legs, and an internal dust removal component is arranged on one side of the shell; a base, the base is arranged at the bottom of the shell, and a filter is installed in the shell, a spray head is arranged on the inner wall of the base, the spray head is connected to the external water supply structure, a drying structure is arranged on the back of the base, and the back of the drying structure is docked with the hoist.

[0038] The spray head 23 is arranged on the swing mechanism, and the swing mechanism is used to drive the spray head 23 to swing.

[0039] In this embodiment, the reciprocating mechanism includes a motor 11 arranged on one side of the base 5, and a cam 12 is sleeved on the output shaft of the motor 11, a cam groove is opened around the cam 12, and a reciprocating rod 13 is slidably installed in the cam groove, the reciprocating rod 13 is vertically slidably installed on the base 5, and a connecting rod 15 is fixedly installed on the reciprocating rod 13.

[0040] In this embodiment, the vibration mechanism includes a sliding groove 6 opened on the inner wall of the base 5, and a sliding rod 7 is fixedly installed in the sliding groove 6, a sliding block 8 is slidably installed on the sliding rod 7, and the sliding block 8 is fixedly installed on the filter screen 9, a spring 10 is sleeved on the sliding rod 7, and the two ends of the spring 10 are fixedly connected to the sliding block 8 and the inner wall of the sliding groove 6 respectively.

[0041] In this embodiment, a push plate 14 is fixedly mounted on the top end of the reciprocating rod 13 , and the push plate 14 is in contact with the sliding block 8 .

[0042] In this embodiment, the swing mechanism includes a rack 16 fixedly mounted on the connecting rod 15, and the rack 16 is meshed with a gear 17, a first bevel gear 18 is fixedly mounted on the gear 17, and the first bevel gear 18 is meshed with a second bevel gear 19, and a rotating column 21 is fixedly mounted on the second bevel gear 19.

[0043] In this embodiment, a rotation groove 20 is formed on the base 5 , and a rotation column 21 is rotatably installed in the rotation groove 20 . A rotation block 22 is fixedly installed on the rotation column 21 , and a spray head 23 is fixedly installed on the rotation block 22 .

[0044] In this embodiment, the shell 1, the shot blasting structure 2, the shot blasting head 3, the fan 4, the base 5, the filter 9 and the spray head 23 are all prior art, which are the shell, shot blasting structure, shot blasting head, fan, base, filter and spray head in a shot blasting machine with a dust-proof structure disclosed in the patent document with public announcement number: CN217801104U.

[0045] In this embodiment, when in use, the hanger is driven into the shell 1, and the shot blasting structure 2 and the shot blasting head 3 are started to perform shot blasting, so that the workpiece on the hanger is processed. During the processing, the fan 4 starts to work to extract the air in the shell 1 to reduce the dust in the shell 1. During the processing, the shot material continuously drives the waste chips to fall into the base 5, and the spray head 23 in the base 5 rinses the shot material. The waste chips are driven by the water flow to pass through the filter screen 9 and fall to the bottom of the base 5.

The shot material moves backward to the drying structure by utilizing the inclination of the filter screen 9, and is then lifted by the elevator to enter the shot blasting structure 2 again; the above is the prior art, and specific reference may be made to a shot blasting machine with a dustproof structure disclosed in the patent document of the public announcement number: CN217801104U;

[0046] At the same time, when in use, the motor 11 is started, and the motor 11 drives the cam 12 to rotate. Due to the structure of the cam 12, when the cam 12 rotates, the reciprocating rod 13 sliding in the cam groove provided on the cam 12 will reciprocate vertically, thereby driving the push plate 14 to reciprocate. When the push plate 14 moves upward, it will push the sliding block 8 to slide on the sliding rod 7, compressing the spring 10, thereby driving the filter screen 9 to move upward. When the push plate 14 moves downward, under the action of gravity and the spring 10, the sliding block 8 drives the filter screen 9 to move downward, and so on and so forth, vibration is achieved, thereby improving the filtering efficiency.

[0047] At the same time, the reciprocating movement of the reciprocating rod 13 will drive the rack 16 to move reciprocally through the connecting rod 15, thereby driving the gear 17 to rotate reciprocatingly, and the gear 17 drives the first bevel gear 18 to rotate, thereby driving the rotating column 21 to rotate through the second bevel gear 19, and the rotating column 21 drives the spray head 23 to rotate reciprocatingly through the rotating block 22 to achieve swinging, expand the spray range, and enhance the cleaning effect.

In this way, when the rack 16 moves back and forth, the spray head 23 is also driven to swing through the gear 17, the first bevel gear 18, the second bevel gear 19, the telescopic column, the telescopic rod and the rotating block 22. At the same time, the rack 16 drives the telescopic rod to slide vertically on the telescopic column through the connecting block without affecting the rotation. The telescopic rod drives the spray head 23 to move vertically through the rotating block 22, thereby realizing the swing and vertical reciprocating movement of the spray head 23, and further improving the spray range.
