Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a sandblasting component for a sandblasting machine. Background Technique

[0002] A sandblasting machine is a mechanical device that can use abrasives (including metal abrasives and non-metal abrasives) with the help of compressed air power and spray them onto the surface of workpieces. The sandblasting machine uses compressed air as power to form a high-speed jet beam and sprays the abrasives onto the surface of the workpieces to be processed at high speed. Due to the impact and cutting action of the abrasives on the surface of the workpieces, the surface of the workpieces obtains a certain degree of cleanliness and different roughness, its mechanical properties are improved, thereby improving the fatigue resistance of the workpieces, increasing the adhesion between it and the coating, and prolonging the durability of the coating film. At the same time, the sandblasting machine can also remove impurities, miscellaneous colors and oxide layers on the surface of the workpieces, roughen the surface of the medium, eliminate the residual stress of the workpieces, and improve the surface hardness of the base material. The sandblasting component of the sandblasting machine is its core part, including a spray gun, a pressure device, a conveying device and other auxiliary components, etc. These components cooperate together to realize the sandblasting function of the sandblasting machine. The existing sandblasting components have a single function and only have the sandblasting function, and the effect is relatively limited. Therefore, it is necessary to design a sandblasting component for a sandblasting machine to solve the problem. Summary of the Invention

An inner pipe is fixedly installed in the main body, and a partition is fixedly installed in the inner pipe. A cleaning chamber and a sandblasting chamber are opened in the inner pipe, and the cleaning chamber and the sandblasting chamber are respectively connected with the collection chamber and the material injection chamber. The cleaning chamber and the sandblasting chamber are respectively connected with an air extraction port and a sandblasting head through the inner pipe. A rotating frame is rotatably connected in the main body, a driving motor is arranged in the connecting seat, and an output shaft of the driving motor is connected with a driving gear. An outer chamber is opened in the main body, a sealing frame is fixedly installed on the top of the rotating frame, and an inlet and outlet is connected with the main body on one side of the outer chamber.

[0006] Preferably, the bottoms of the collection chamber and the material injection chamber are both designed to be inclined to facilitate the flow of the grit, and the top of the collection chamber is in a shape that converges towards the air extraction pipe, which is convenient for extracting the grit and preventing it from accumulating in the collection chamber.

[0007] Preferably, there are several air extraction ports and sandblasting nozzles, which are arranged in an array to increase the sandblasting and cleaning range. Both the air extraction ports and the sandblasting nozzles adopt an embedded design to prevent impact during the rotation of the sealing frame, playing a protective role.

[0008] Preferably, the driving gear is meshed with the rotating frame, and a gear groove adapted to the driving gear is provided on the outer side of the rotating frame for controlling the rotation of the rotating frame and the sealing frame around the inner pipe as the center.

The sealing frame adopts a semi-circular ring structure design to avoid the situation of completely blocking the air extraction ports and the sandblasting nozzles.

[0010] The beneficial effects of the present utility model are as follows:

[0011] In the present utility model, sand and gravel are injected into the injection cavity through the injection pipe, and sandblasting is carried out by spraying through the sandblasting nozzles and the inlet and outlet. At the same time, the sand and gravel can be sucked into the collection cavity through the inlet and outlet and the air extraction ports by using the suction pipe and discharged for cleaning work. It only needs to use the driving motor and the driving gear to control the rotation of the rotating frame and the sealing frame to complete.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Embodiment: Refer to Figures 1-4 , a sandblasting component for a sandblasting machine, including a main body 1. A connecting seat 2 is connected and installed on one side of the main body 1. An air extraction pipe 3 and a feeding pipe 4 are fixedly installed on the top of the main body 1. The air extraction pipe 3 and the feeding pipe 4 are respectively connected with a collection chamber 5 and a feeding chamber 6 through the main body 1. The bottoms of the collection chamber 5 and the feeding chamber 6 are both designed to be inclined to facilitate the flow of grit. The top of the collection chamber 5 is concentrated towards the air extraction pipe 3 to facilitate the extraction of grit and prevent it from accumulating in the collection chamber 5. An inner pipe 7 is fixedly installed in the main body 1, and a partition 8 is fixedly installed in the inner pipe 7. A cleaning chamber 9 and a sandblasting chamber 10 are formed in the inner pipe 7, and the cleaning chamber 9 and the sandblasting chamber 10 are respectively connected with the collection chamber 5 and the feeding chamber 6. The cleaning chamber 9 and the sandblasting chamber 10 are respectively connected with an air extraction port 11 and a sandblasting head 12 through the inner pipe 7. A rotating frame 13 is rotatably connected in the main body 1. A driving motor 14 is arranged in the connecting seat 2, and an output shaft of the driving motor 14 is connected with a driving gear 15. An outer chamber 16 is formed in the main body 1. A sealing frame 17 is fixedly installed on the top of the rotating frame 13. There are several air extraction ports 11 and sandblasting heads 12, and they are arranged in an array to increase the sandblasting and cleaning range. The air extraction ports 11 and the sandblasting heads 12 both adopt an internal design to prevent the sealing frame 17 from colliding during rotation and play a protective role. The driving gear 15 is meshed with the rotating frame 13, and a gear groove adapted to the driving gear 15 is formed on the outer side of the rotating frame 13 to control the rotation of the rotating frame 13 and the sealing frame 17 around the inner pipe 7 as the center.
