Description

Technical Field

[0001] The utility model relates to the technical field of rubber door curtains, and specifically discloses a rubber door curtain and a shot blasting device comprising the rubber door curtain. Background Art

[0002] Shot blasting equipment, also known as shot blasting machine, shot blasting cleaning machine, sandblasting rust removal equipment or sandblasting machine, is an important mechanical equipment, mainly used to clean or process metal surfaces. It projects steel shots or other granular materials onto the metal surface to be processed through a high-speed rotating shot blasting wheel, and removes impurities such as dirt, oxides, scratches, welding slag, etc. on the surface by high-speed impact and friction, thereby improving the quality and morphology of the metal surface.

[0003] The rubber door curtain is a protective device for shot blasting equipment. The most common rubber door curtain is made of high-quality PVC material. The rubber door curtain in the shot blasting equipment is mainly made of a mixture of rubber, synthetic rubber and various reinforcing materials, and has multiple excellent properties, such as fire prevention, sound insulation, protection, dust prevention and aesthetics. In the prior art, since the rubber door curtain is worn out quickly due to long-term high-speed shot blasting, spring steel is generally embedded in the rubber sheet to make the rubber door curtain, making it stronger and ensuring the rebound toughness, ensuring that the shot in the shot blasting equipment will not splash out, and increasing the service life of the rubber door curtain.

[0004] However, this type of rubber door curtain made of spring steel embedded in the rubber plate may encounter workpieces that are relatively large in size and relatively light in weight in actual applications. The rubber door curtain installed on the side wall of the chamber cannot be pushed open, resulting in the inability to shot blast the workpiece, affecting the normal production rhythm. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a rubber door curtain and shot blasting equipment including the same, so as to solve the problem that when encountering a workpiece with relatively large size and relatively light weight, the rubber door curtain installed on the side wall of the chamber body cannot be pushed open, resulting in the workpiece being unable to be shot blasted, affecting the normal production rhythm.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] A rubber door curtain includes a plurality of elastic rubber plates arranged side by side, the elastic rubber plates are embedded with spring steel, and the elastic rubber plates are detachably arranged on a rotating shaft in the radial direction; the upper and lower ends of the rotating shaft are both rotatably arranged. The rotating shaft is rotatably arranged to reduce the resistance of opening the rubber door curtain, ensure that workpieces with relatively large size and relatively light weight can push open the rubber door curtain and enter the shot blasting equipment for shot blasting treatment, and ensure the production rhythm.

[0008] Preferably, a fixing plate is fixedly arranged on the outer wall of the rotating shaft, and the elastic rubber plate is arranged at the edge of the fixing plate by means of bolts, so as to facilitate the fixing of the elastic rubber plate.

[0009] Preferably, a tension spring is fixedly provided on the side wall of the fixed plate; one end of the tension spring away from the fixed plate is provided on the outside of the shot blasting device. The provision of the tension spring can increase the resistance of the elastic rubber plate to rotate toward the outside of the shot blasting device, thereby preventing the high-speed shot blasting in the shot blasting device from splashing outward; and after the workpiece pushes the elastic rubber plate open and enters the shot blasting device, the elastic rubber plate can be pulled back to ensure sealing; furthermore, the resistance of the elastic rubber plate to rotate toward the inside of the shot blasting device and be pushed open can be increased, thereby preventing the situation in which the elastic rubber plate is pushed open by external wind force due to the small resistance of the rotating shaft.

[0010] Preferably, the length direction of the elastic rubber plate is perpendicular to the center line of the rotating shaft.

[0011] Preferably, the upper end of the rotating shaft is rotatably arranged on the bearing seat; and the lower end of the rotating shaft is rotatably arranged on the base.

[0012] A shot blasting device comprises the rubber door curtain.

[0013] The beneficial effects of the utility model are:

[0014] 1. The rotating shaft reduces the resistance to opening the rubber door curtain, ensuring that workpieces with larger size and lighter weight can push open the rubber door curtain and enter the shot blasting equipment for shot blasting, thus ensuring the production rhythm.

[0015] 2. The setting of the tension spring can increase the resistance of the elastic rubber plate to rotate toward the outside of the shot blasting equipment, thereby preventing the high-speed shots in the shot blasting equipment from splashing out; and after the workpiece pushes the elastic rubber plate into the shot blasting equipment, the elastic rubber plate can be pulled back to ensure the sealing; furthermore, the resistance of the elastic rubber plate to rotate toward the inside of the shot blasting equipment and be pushed open can be increased, thereby preventing the situation where the resistance of the rotating shaft is too small, resulting in the elastic rubber plate being pushed open by external wind.

The rotating shaft 2 is rotatably arranged, which reduces the resistance of opening the rubber door curtain, ensures that a workpiece with a relatively large size and a relatively light weight can push open the rubber door curtain and enter the shot blasting equipment for shot blasting treatment, and ensures the production rhythm.

[0025] In the above arrangement, a fixing plate 3 is fixedly arranged on the outer wall of the rotating shaft 2; the elastic rubber plate 1 is arranged at the edge of the fixing plate 3 by means of bolts 4, so as to facilitate the fixing of the elastic rubber plate 1. The length direction of the elastic rubber plate 1 is perpendicular to the center line of the rotating shaft 2.
