Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a closed automatic sandblasting machine with a protective mechanism. Background Art

[0002] With the advent of the Industrial Revolution, the rapid development of manufacturing has placed higher demands on surface treatment technology, and sandblasting machines have gradually become specialized and large-scale. Sandblasting machines primarily utilize a power source such as compressed air or high-pressure water to accelerate abrasives (such as sand, steel shot, and glass beads) onto the surface of a workpiece. When the abrasive impacts the workpiece surface, it produces cutting, impacting, and grinding effects, thereby achieving the purpose of cleaning, strengthening, or decorating the workpiece surface.

[0003] Chinese patent CN 212683620 U discloses a closed automatic sandblasting machine with a protective mechanism. The machine comprises a housing, a support leg fixedly connected to the bottom of the housing, a door panel hingedly connected to the center of the top of the housing via a hinge axis, an observation window mounted at the center of the door panel, and two symmetrically spaced connecting blocks fixedly connected to the side of the door panel near the housing. This utility model enhances the protective performance of the protective mechanism by utilizing the function of a drive motor and a sealing roller film, thereby preventing dust from harming workers.

[0004] However, the lower end of the sealing roller film of the above mechanism cannot effectively shield the space below the conveyor belt due to the obstruction of the conveyor belt, so that the dust generated by the sandblasting machine during operation will still fly out from the space below the conveyor belt.

[0022] like Figure 1-4 As shown, in this embodiment, a closed automatic sandblasting machine with a protective mechanism includes a sandblasting machine body 1, a feed port 2 and a discharge port 3 are respectively provided at both ends of the sandblasting machine body 1, a conveyor belt 4 connecting the feed port 2 and the discharge port 3 is provided on the sandblasting machine body 1, and dust-proof shielding mechanisms are provided on the outer sides of the feed port 2 and the discharge port 3. The dust-proof shielding mechanism includes baffles 5 vertically arranged on both sides of the conveyor belt 4, and the two baffles 5 are rotated toward one end thereof to be provided with a door panel 6, and a telescopic cover 7 is provided at the inward upper end of the door panel 6. When the door panel 6 is in a vertical state, the bottom of the telescopic cover 7 is located at the top of the baffle 5.

[0023] In this embodiment, the baffle 5 includes two parallel and spaced vertical plates 5-1, a pulley 1 5-2 is rotatably provided between the outward ends of the two vertical plates 5-1, and a pulley 2 5-3 is rotatably provided between the inward ends of the two vertical plates 5-1. The pulley 1 5-2 and the pulley 2 5-3 are connected by a belt, and the two pulleys 1 5-2 are connected by a rotating shaft 5-4. The front pulley 2 5-3 is driven by a driving mechanism 10. In this embodiment, the driving mechanism 10 includes a pulley 2 5-3 coaxially provided. Pulley three 10-1, pulley three 10-1 is rotatably arranged on the outside of the baffle 5, and a pulley four 10-2 is rotatably arranged between the two pulleys three 10-1, and the pulley four 10-2 is respectively connected to the two pulleys three 10-1 through belt transmission. The driving mechanism 10 also includes a driving motor 10-3, and the output end of the driving motor 10-3 is connected to the center position of the pulley four 10-2. A number of rollers are rotatably arranged on the front and rear sides of the inner end of the telescopic cover 7. When the door panel 6 is in a vertical state, the rollers are located on the upper surface of the belt.

[0024] In this embodiment, the outward side of the belt and the outer surface of the roller are both wrapped with magnetic material, and the roller is magnetically connected to the outward side of the belt.

[0025] In order to improve the sealing between the door panel 6 and the vertical plate 5-1, in this embodiment, a sealing strip 8 is provided on the outward end surface of the vertical plate 5-1.

[0026] In order to improve the sealing between the telescopic cover 7 and the sandblasting machine body 1, in this embodiment, a sealing strip 9 is provided on the inner end surface of the telescopic cover 7.

[0027] The working principle and beneficial effects of the above technical solution are:

[0028] In this embodiment, the door panel 6 is initially in a horizontal, outwardly flipped state. During use, the workpiece is first placed on the conveyor belt 4. The two door panels 6 on the outside of the feed port 2 and the discharge port 3 are then erected so that the rollers fall onto the belts. The controller then controls the drive motor 10-3 to rotate, thereby driving the two telescopic covers 7 to move toward each other. During the unfolding of the telescopic covers 7, the rollers and the belts remain relatively stationary. When the inward end of the telescopic covers 7 contacts the sandblasting machine body 1, rolling friction occurs between the rollers and the belts. The drive motor 10-3 is then turned off, and the sandblasting machine body 1 is started to perform the sandblasting operation. After the sandblasting operation is completed, the controller controls the drive motor 10-3 to rotate in the opposite direction, opening the telescopic covers 7. After the telescopic covers 7 have completely retracted, the drive motor 10-3 is turned off, and the door panels 6 are folded outward.

[0029] Compared with the prior art, the present invention can shield the entire conveyor belt 4 through the door panel 6 and the telescopic cover 7, thereby improving the sealing performance and effectively preventing dust from flying out.

[0030] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
