Description

Technical Field

[0001] The utility model relates to the field of drum-type shot blasting machines, in particular to an easy-to-clean structure for drum-type shot blasting machines. Background Art

[0002] The drum shot blasting machine is suitable for cleaning various castings and forgings that are resistant to collisions and scratches. It is an ideal equipment for cleaning residual sand and scale on the surface of workpieces in small heat treatment workshops. It mainly consists of a drum, separator, shot blaster, elevator, and reduction motor. The drum shot blasting machine mainly uses a high-speed rotating impeller to throw projectiles onto the workpieces that are continuously turned in the drum, thereby achieving the purpose of cleaning the workpieces.

[0003] Sandblasting the surface of a casting produces a certain amount of debris. This debris rotates with the casting inside the drum. After the casting is processed, most of the debris is discharged. However, some debris can adhere to the inner wall of the drum, and excessive accumulation can seriously affect the treatment effect. Currently, drum shot blasting machines have a fixed rubber plate on the inner surface of the drum. The rubber plate has fixed strip-shaped protrusions at intervals along the circumference. The inner surface of the rubber plate does not have a structure that can facilitate disassembly, making it difficult to disassemble and maintain when the rubber plate wears out. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the utility model provides an easy-to-clean structure for a drum-type shot blasting machine. The cleaning structure can be detachably fixed to the inner surface of the rubber plate, which is convenient for maintenance and effectively solves the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solutions: a drum-type shot blasting machine easy-to-clean structure, comprising a drum, a rubber plate fixedly provided on the inner surface of the drum, a plurality of first strip-shaped protrusions fixedly provided on the inner surface of the rubber plate in a circumferential direction, a rubber sleeve detachably fixedly provided on the inner side surface of the rubber plate, the rubber sleeve being of a C-shaped structure as a whole, a plurality of second strip-shaped protrusions fixedly provided on the inner surface of the rubber sleeve in a circumferential direction at intervals, the positions of the second strip-shaped protrusions corresponding to the positions of the first strip-shaped protrusions, the outer surfaces of the rubber sleeve at the second strip-shaped protrusions respectively inwardly embedded with rectangular grooves that engage with the first strip-shaped protrusions, the outer surfaces of the rubber sleeves on the left and right sides of the rectangular groove and the inner surfaces of the rubber plates on both sides of the first strip-shaped protrusions are provided with mutually cooperating fixing structures;

[0006] The two ends of the rubber sleeve are respectively detachably fixedly connected to the rubber plate.

[0007] As a preferred technical solution, the fixing structure includes a first strong magnetic block fixed on the left and right sides of the first strip protrusion, and a second strong magnetic block fixed on the outer surface of the rubber sleeve on the left and right sides of the rectangular groove to attract and cooperate with the first strong magnetic block.

[0008] As a preferred technical solution, there are three first strong magnetic blocks on both sides of each first strip-shaped protrusion, which are evenly distributed vertically.

[0009] As a preferred technical solution, there are three second strong magnetic blocks on both sides of each rectangular groove, which are evenly distributed vertically.

[0010] As a preferred technical solution, fixing bolts that cooperate with the rubber plate are screwed outwards at both ends of the rubber sleeve.

[0011] As a preferred technical solution, the rubber sleeve is a composite structure, including an inner flexible rubber sleeve, and a hard rubber sleeve is bonded to the outer side of the flexible rubber sleeve.

[0012] As a preferred technical solution, circumferential reinforcing ribs are fixedly provided in the hard rubber sleeve at intervals above and below.

The outer surfaces of the rubber sleeve on the left and right sides of the rectangular groove and the inner surfaces of the rubber plate on both sides of the first strip-shaped protrusion are provided with mutually cooperating fixing structures. When in use, when the parts are sandblasted, they first rub and collide with the inner rubber sleeve, thereby protecting the rubber plate. In addition, the rubber sleeve can be removed from the rubber plate, which is convenient for cleaning debris and regular replacement.

[0015] 2. The utility model includes a fixing structure including a first strong magnetic block fixed on the left and right sides of the first strip-shaped protrusion, and a second strong magnetic block fixed on the outer surface of the rubber sleeve on the left and right sides of the rectangular groove to attract and cooperate with the first strong magnetic block.
