The production of the elastic iron backing plate for high-speed turnout needs a shot blasting process. The iron backing plate needs to be hoisted onto a wheel sliding type conveying mechanism during the shot blasting operation, and then enters the shot blasting machine for the shot blasting process. Subsequently, the shot blasting machine uses passivated steel wire shot to blast the iron backing plate to remove surface rust, increase surface roughness and enhance adhesion. Then it enters the next process. In order to enhance the effectiveness of the iron backing plate during the shot blasting process, ensure that the entire iron backing plate can be effectively cleaned in the shot blasting machine, and prevent the passivated steel wire shot from splashing out of the shot blasting machine to cause production cost waste and poor production environment, we need to reinforce the shot blasting machine sealing device so that the passivated steel wire shot can be fully utilized during the iron backing plate shot blasting operation, thereby saving production cost and improving production environment.

[0003] Currently, the closed tooling of the shot blasting machine for the elastic iron backing plate of the turnout has a brush type front and rear door and an open top.
