Description

Technical Field

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

[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles to clean or strengthen the surface of castings. The machine can simultaneously remove sand, core and clean the castings. In some areas, it is also verbally called a sandblasting machine or a sandblasting machine. After the shot blasting machine uses shot to cast the surface of the material, iron filings and impurities are attached to the shot, and a screening mechanism is needed to clean the shot.

[0003] For example, Chinese patent CN218137348U discloses a turntable shot blasting machine, which can limit the parts through the cooperation of connecting rods, movable blocks, and clamping plates to avoid the parts being thrown out during the rotation process, and the friction between the parts and the clamping plates can be increased by rubber pads.

[0004] However, in the existing shot blasting device, the projectiles need to be recovered during the shot blasting process. Generally, a collecting bucket is placed directly below the projectile outlet to collect the projectiles. When the workpiece is shot blasted, iron filings and other impurities remaining on the workpiece will be separated from the workpiece surface. When the projectiles are recovered, these impurities will also flow out with the projectiles. The projectiles that flow out cannot be directly put into the shot blasting machine for use. The staff is required to manually clean the projectiles, which is labor-intensive and time-consuming and also affects the continuity of the shot blasting process. Therefore, a shot blasting machine is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a shot blasting machine, which has the advantages of conveniently cleaning iron filings and other impurities remaining on some workpieces and separating them from the workpiece surface, etc., solves the problem that in the existing shot blasting device, the projectiles need to be recovered during the shot blasting process. The existing ones generally place a collecting bucket directly under the projectile outlet to collect the projectiles. However, when the workpiece is shot blasted, iron filings and other impurities remaining on the workpiece will be separated from the workpiece surface. When the projectiles are recovered, these impurities will also flow out with the projectiles. The projectiles that flow out cannot be directly put into the shot blasting machine for use, and the staff are required to manually clean the projectiles, which not only consumes manpower and time, but also affects the continuity of the shot blasting process.

[0006] To achieve the above objectives, the utility model provides the following technical solutions: a shot blasting machine, comprising a processing chamber, the top of which is fixedly connected to a feed pipe with one end penetrating through and extending into the interior of the processing chamber, and a cleaning mechanism is provided inside the processing chamber.

[0007] The cleaning mechanism includes a filter screen movably connected to the interior of the processing chamber, the bottom of the filter screen is fixedly connected to a mounting plate, the back inner wall of the processing chamber is fixedly connected to a motor, the output shafts on the left and right sides of the motor are fixedly connected to cams, and the back inner wall of the processing chamber is fixedly connected to two fixed blocks, the tops of the two fixed blocks are fixedly connected to tension springs, and the tops of the two tension springs are fixedly connected to the bottom of the mounting plate.

[0008] By setting up a cleaning mechanism, when the shot blasting machine on the top polishes the material through shot blasting, iron filings and other impurities remaining on some workpieces and shot blasting will be sent to the processing bin through the feed pipe. The iron filings and shot blasting can be separated by the filter screen inside the processing bin, so that the staff does not need to manually clean the projectiles, thereby improving the continuity of the shot blasting process.

[0009] Furthermore, rectangular through holes matching the width of the filter are provided on both the left and right sides of the processing chamber.

[0010] By setting the above structure, the shot can flow out from the rectangular through hole.

[0011] Furthermore, outer sides of the two cams are in contact with and connected to the bottom of the mounting plate.

[0012] By setting the above structure, the cam can drive the filter to move up and down, achieving a vibration effect.

[0013] Furthermore, two inclined plates are fixedly connected inside the processing bin, and discharge pipes are fixedly connected to opposite sides of the two inclined plates.

[0014] By setting the above structure, the inclined plate can collect iron chips and discharge them from the discharge pipe.

[0015] Furthermore, a first collecting tank is placed on the inner bottom wall of the processing chamber.

[0016] By providing the above structure, the first collecting trough can collect iron filings.

[0017] Furthermore, two support plates are fixedly connected to the outer side of the processing chamber, and a second collecting tank is placed on the top of the two support plates.

[0018] By providing the above structure, the second collecting trough can collect the shot.

[0019] Furthermore, the feeding pipe is funnel-shaped.

[0020] Furthermore, the motor is a dual-axis motor.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The shot blasting machine is provided with a cleaning mechanism. When iron filings and other impurities remaining on some workpieces are fed into a processing bin together with the shot blasting, the iron filings and the shot blasting can be separated by a filter screen inside the processing bin. Thus, the staff does not need to manually clean the shot blasting, thereby improving the continuity of the shot blasting process. BRIEF DESCRIPTION OF THE DRAWINGS
