Technical Field

The invention relates to a shot blasting machine, in particular to a sealing door curtain for the shot blasting machine.

Background

The working principle of the shot blasting machine is that steel shots are sprayed on a component by means of high-speed rotation of the shot blasting machine, so that the surface of the component is clean and has certain roughness. The existing shot blasting machine mainly adopts a single vertical rubber curtain for sealing, and the sealing effect is poor. Therefore, when the shot blasting machine works, a large number of steel shots are shot towards the inlet and outlet directions, the cost of the equipment is increased, and the insecurity of the equipment is increased due to the steel shots at the high-speed shot positions.

Disclosure of Invention

In order to solve the technical problem, the invention provides a sealing door curtain for a shot blasting machine.

According to one aspect of the invention, a sealing door curtain for a shot blasting machine is provided, which comprises a plurality of door curtain assemblies and a door frame, wherein each door curtain assembly comprises a plurality of first door curtains and a plurality of second door curtains, one end of each first door curtain is fixed at the top end of the door frame, the other end of each first door curtain is a free end, two ends of each second door curtain are fixed at two sides of the door frame, the free ends of the first door curtains are connected with the second door curtains, and the middle parts of the second door curtains are disconnected to form vertical intersection seams.

The beneficial effects are as follows: when a workpiece with a groove at the lower part passes through the sealing door curtain, the second door curtain on the second frame and the second door curtain on the third frame can extend into the groove, so that the gap between the workpiece and the sealing door curtain is reduced; the invention adopts the mode that the upper part is vertical and the lower part is transversely provided with the door curtain, thereby improving the sealing performance.

In some embodiments, the first curtain is made of rubber, and the second curtain is made of polycarbonate.

The beneficial effects are as follows: the polycarbonate has strong toughness, the second door curtain can extend into the groove at the lower part of the workpiece, the gap between the workpiece and the door curtain is reduced, the rubber is soft, the gap between the upper part of the workpiece and the sealing door curtain can be reduced, and the sealing performance is improved.

In some embodiments, a plurality of door curtain assemblies are disposed within the door frame, each door curtain assembly is disposed in parallel, the cross-over seam of the first door curtain of each door curtain assembly is disposed in a staggered manner, and the vertical cross-over seam of the second door curtain of each door curtain assembly is disposed in a staggered manner.

The beneficial effects are as follows: when the shot blasting machine works, the steel shots rotating at high speed can fly out of the shot blasting chamber, and after the door curtain assemblies closest to the shot blasting chamber are in the shot blasting positions, the steel shots flying out of the door curtain assemblies close to the shot blasting chamber are better blocked by the latter door curtain assemblies due to the fact that the cross-over seams of the door curtain assemblies are arranged in a staggered mode.

In some embodiments, the first curtain is a double layer.

The beneficial effects are as follows: the double-layer first door curtain has better sealing performance.

Detailed Description

The invention is described in further detail below with reference to the following figures and detailed description: as shown in fig. 1, the present invention provides a sealing door curtain for a shot blasting machine, comprising a plurality of door curtain assemblies 1 and a door frame 2, wherein each door curtain assembly 1 comprises a plurality of first door curtains 11 and a plurality of second door curtains 12. One end of the first door curtain 11 is connected to the door frame 2 through a hook 21, and the other end of the second door curtain 12 is a free end. The two sides of the door frame 2 are provided with mounting plates 22, and the two ends of the second door curtain 12 are fixedly connected to the mounting plates 22 through fixing bolts 23. A gasket 24 is arranged between the fixing bolt 23 and the mounting plate 22, and the gasket 24 plays a role in protecting the mounting plate 22. The middle of the second door curtain 12 is broken to form a vertical intersection seam. The free end of the first curtain 11 interfaces with but is not connected to the second curtain 12. The first curtain 11 and the second curtain 12 of the curtain assembly 1 form a plane. In the present embodiment, the door frame 2 is provided with four curtain assemblies 1.

First door curtain 11 is double-deck rubber, and rubber is softer, and the gap between reducible work piece upper portion and the sealed door curtain improves sealing performance, and double-deck sealed effect is better. The second door curtain 12 is made of polycarbonate, and the polycarbonate has strong toughness, so that the second door curtain 12 can extend into a groove at the lower part of the workpiece, and gaps between the workpiece and the door curtains are reduced.

As shown in fig. 2, the joint of the first door curtain 11 of each door curtain assembly 1 is arranged in a staggered manner, and the first door curtain 11 of the subsequent door curtain assembly 1 is shown by a dotted line in fig. 2. As shown in fig. 3, the vertical joint of the second door curtain 12 of each door curtain assembly 1 is offset, and the vertical joint of the second door curtain 12 of the subsequent door curtain assembly 1 is indicated by a dotted line in fig. 3. When the shot blasting machine works, the steel shots rotating at a high speed can fly out of the shot blasting chamber, and after the door curtain assemblies 1 at the positions where the steel shots fly out are closest to the shot blasting chamber, because the joint seams of the door curtain assemblies 1 are arranged in a staggered mode, the latter door curtain assemblies 1 have a good blocking effect on the steel shots flying out of the door curtain assemblies 1 close to the shot blasting chamber.

When the invention works, when a workpiece with a groove at the lower part passes through the sealing door curtain, the second door curtain 12 can extend into the groove, so that the gap between the workpiece and the sealing door curtain is reduced; according to the invention, the mode that the first door curtain 11 is vertically arranged at the upper part and the second door curtain 12 is transversely arranged at the lower part is adopted, so that the sealing performance of the shot blasting chamber when a common workpiece passes through the sealed door curtain can be effectively ensured, the sealing performance of the shot blasting chamber when a workpiece with a groove at the lower part passes through the sealed door curtain can be ensured, in addition, the joint seams of the first door curtain 11 and the second door curtain 12 of each door curtain component 1 are arranged in a staggered mode, and the sealing performance of the workpiece entering the shot blasting chamber through the sealed door curtain is also improved.

While only the preferred embodiments of the sealing curtain of the present invention have been described, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
