Description

Technical Field

[0001] This utility model relates to the field of sandblasting machines, and in particular to an automatic sandblasting device for sandblasting machines. Background Technology

[0002] A sandblasting machine uses compressed air or high-pressure water to drive abrasive particles to be sprayed onto the surface of a workpiece at high speed. The impact and friction of the abrasive particles are used to achieve cleaning, rust removal, deburring, or increasing surface roughness.

[0003] Existing products are formed after sandblasting and sintering. However, after sandblasting, sand particles remain on the product. These residual sand particles affect the overall appearance quality of the product during sintering. The current method of sand removal is usually done manually by blowing sand, but this method has low sand removal efficiency and the quality of the sintered finished product cannot be guaranteed, which is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic sandblasting device for a sandblasting machine. It has an ingenious structure and can automatically and efficiently remove sand from blind holes and surfaces on the material tray, thereby ensuring the overall sintering quality of the product. It is efficient and convenient.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a cover with an inlet and an outlet, and a working platform set inside the cover. A frame is mounted on the working platform. Multiple parallel sand-blowing components are provided on the frame to remove residual sand from the products. A feeding channel is provided on the frame, corresponding one-to-one with each sand-blowing component, through which a conveyor belt and a tray containing multiple products can pass. The feeding channel is connected to the inlet and outlet of the cover and is located between the sand-blowing components and the working platform. The sand-blowing components include a first air-blowing component that blows air into blind holes on the products in the tray, and a second air-blowing component that blows air onto the surface of the products in the tray. The first air blowing assembly and the second air blowing assembly are sequentially arranged on the frame along the running direction of the conveyor belt. The first air blowing assembly includes a first fixed air nozzle plate fixed on the frame and a plurality of first universal adjustable air nozzles arranged on the first fixed air nozzle plate and capable of omnidirectional rotation. The second air blowing assembly includes a pneumatic motor fixed on the frame, a second fixed air nozzle plate fixed on the output end of the pneumatic motor, and a plurality of second universal adjustable air nozzles arranged on the second fixed air nozzle plate and capable of omnidirectional rotation. Each first universal adjustable air nozzle blows sand into the blind holes of each product in the feeding tray of the feeding channel, and each second universal adjustable air nozzle blows sand into the surface of each product by driving the second fixed air nozzle plate through the pneumatic motor.

[0006] Furthermore, each of the first universal adjustment valves and each of the second universal adjustment valves is arc-shaped.

[0007] Furthermore, the aforementioned frame includes a first support profile and a second support profile arranged parallel to each other within the housing. Between the first and second support profiles are an upper support group corresponding to each second air blowing assembly and a lower support group corresponding to each first air blowing assembly. The upper support group includes two opposing and parallel upper supports, each of which is mounted between the first and second support profiles and connected by a connecting plate. The pneumatic motor is fixed to the connecting plate. The second fixed nozzle plate and each second universal adjustable nozzle are located between the upper supports. The lower support group includes two opposing and parallel lower supports, with each feeding channel located between the opposing lower supports. The first fixed nozzle plate is fixed to the first support profile and located between the opposing lower supports. When the product in the conveyor belt feed tray passes between the lower supports, the first universal adjustable nozzles blow away the blind holes on the product. When the product in the conveyor belt feed tray passes between the upper supports, the second universal adjustable nozzles blow away the surface of the product.

[0008] Furthermore, each lower support is fixed with a guide plate at its bottom, which can guide the material tray on the conveyor belt into the feeding channel. Each guide plate is provided with a guide slope, and the guide slopes on each guide plate are arranged opposite to each other to form a guide port that can guide the material tray into the feeding channel.

[0009] Furthermore, the frame also includes a third support profile arranged parallel to the first and second support profiles. The third support profile is provided with multiple sand removal air knives, each of which is located above each feeding channel and removes floating sand from the product surface as the material tray on the conveyor belt passes by.

[0010] This utility model has positive effects: (1) By setting a first air blowing component and a second air blowing component on the frame, and installing each of the first universal adjustment nozzles on the first fixed nozzle plate on the first air blowing component, the angle can be adjusted according to the blind holes on each product, and the sand in the blind holes on the product can be blown away in a comprehensive manner. The angle of each of the second universal adjustment nozzles on the second fixed nozzle plate on the second air blowing component can also be adjusted according to the shape of the product. Then, the outer surface of the product is thoroughly and efficiently desanded by the drive of the pneumatic motor. This effectively solves the problem of low efficiency caused by manual desanding in the prior art and the problem of sand on the appearance of the finished product after sintering. It greatly improves the comprehensiveness and efficiency of desanding of the product, and also ensures the quality of the product after sintering. The structure is ingenious, convenient and practical.

[0011] (2) By setting the first universal adjustment nozzle and the second universal adjustment nozzle of each product into an arc shape, this utility model can better adapt to the blind holes at various positions on the product and the different shapes of each product, so as to achieve comprehensive sand removal while also having good adjustability and applicability.

[0012] (3) This utility model sets an upper support group and a lower support group on the first support profile and the second support profile. The upper support group is set as two parallel upper supports and the pneumatic motor is set on each upper support, which effectively ensures the stability of the second air blowing component in the sand removal process. At the same time, the lower support group is set as two lower supports working together and the feeding channel is set between each lower support, which can effectively guide the material tray. Meanwhile, the first fixed air nozzle plate is fixed on the first support profile, which effectively ensures the stability of each first universal adjustable air nozzle in the sand blowing process. It is convenient and practical.

[0013] (4) By setting guide plates on each lower support and setting guide slopes on the guide plates to form a guide port, the present invention can more accurately guide the material tray into the feeding channel, and can also accurately correct the deviation of the material tray, while ensuring the accuracy and efficiency of the subsequent sand blowing.

[0014] (5) By setting a sand removal air knife on the third support profile, this utility model can further remove sand from the outer surface of the product, further ensuring the comprehensiveness of sand removal, and also further ensuring the cleanliness of the product.

The frame 2 is provided with a feeding channel corresponding to each sand-blowing component and through which a conveyor belt and a tray with multiple products mounted on the conveyor belt can pass. The feeding channel is connected to the inlet 11 and outlet 12 of the housing 1. The feeding channel is located between the sand-blowing components and the working platform 10. The sand-blowing components include a first air-blowing component 3 that blows air onto blind holes in the products in the tray, and a second air-blowing component 4 that blows air onto the surface of the products in the tray. The first air-blowing component 3 and the second air-blowing component 4... The air assembly 4 is sequentially arranged on the frame 2 along the running direction of the conveyor belt. The first air blowing assembly 3 includes a first fixed air nozzle plate 31 fixed on the frame 2 and a plurality of first universal adjustable air nozzles 32 arranged on the first fixed air nozzle plate 31 and rotatable in all directions. The second air blowing assembly 4 includes a pneumatic motor 41 fixed on the frame 2, a second fixed air nozzle plate 42 fixed on the output end of the pneumatic motor 41 and a plurality of second universal adjustable air nozzles 43 arranged on the second fixed air nozzle plate 42 and rotatable in all directions. Each first universal adjustable air nozzle 32 blows sand into the blind holes of each product in the feeding tray of the feeding channel. Each second universal adjustable air nozzle 43 blows sand into the surface of each product by driving the second fixed air nozzle plate 42 through the pneumatic motor 41.

[0023] Each of the first universal adjustment valves 32 and each of the second universal adjustment valves 43 are arc-shaped.

[0024] The frame 2 includes a first support profile 21 and a second support profile 22 parallel to each other and assumed to be inside the housing 1. An upper support group corresponding to each second air blowing assembly 4 and a lower support group corresponding to each first air blowing assembly 3 are provided between the first support profile 21 and the second support profile 22. The upper support group includes two opposing and parallel upper supports 24, each upper support 24 being erected between the first support profile 21 and the second support profile 22. Each upper support 24 is connected by a connecting plate 26. The pneumatic motor 41 is fixed to the connecting plate 26. The second fixed air nozzle plate 42 and each first air blowing assembly 3... Two universal adjustable air nozzles 43 are located between each upper bracket 24. The lower bracket group includes two opposite and parallel lower brackets 25. Each feeding channel is located between the opposite lower brackets 25. The first fixed air nozzle plate 31 is fixed on the first support profile 21 and located between the opposite lower brackets 25. Each first universal adjustable air nozzle 32 blows the blind holes on the product when the product in the conveyor belt feed tray passes between each lower bracket 25. Each second universal adjustable air nozzle 43 blows the surface of the product when the product in the conveyor belt feed tray passes between each upper bracket 24.

[0025] Each lower support 25 has a fixed guide plate 27 at its bottom, which can guide the material tray on the conveyor belt into the feeding channel. Each guide plate 27 has a guide slope 28. The guide slopes 28 on each guide plate 27 are arranged opposite to each other and form a guide port that can guide the material tray into the feeding channel.

[0026] The frame 2 also includes a third support profile 23 arranged parallel to the first support profile 21 and the second support profile 22. The third support profile 23 is provided with a plurality of sand removal air knives 5. Each sand removal air knife 5 is arranged above each feeding channel and removes the floating sand on the product surface when the material tray on the conveyor belt passes by.

[0027] The working principle of this utility model is as follows: In the process of using this utility model, a material tray filled with sandblasted products is placed on a conveyor belt. The conveyor belt is installed in each feeding channel, and then each material tray is fed. During the feeding process, the guide slope 28 on each guide plate 27 forms a guide port to correct and guide the material tray, thereby ensuring that the material tray can accurately enter the feeding channel. Then the conveyor belt drives each material tray to feed.

[0028] During the feeding process, each of the first universal adjustment nozzles 32 on each of the first fixed air nozzle plates 31 is connected to an external air pump. Since each of the first universal adjustment nozzles 32 can rotate in all directions, the angle of each of the first universal adjustment nozzles 32 can be adjusted in advance according to the position of the blind holes on the product. When each product on the material tray enters the feeding channel and passes under the first air blowing assembly 3, each of the first universal adjustment nozzles 32 blows air into the blind holes on each product, thereby blowing away the residual sand in each blind hole.

[0029] Then the conveyor belt continues to feed the material. When it passes under the second air blowing component 4, each of the second universal adjusting air nozzles 43 removes sand from the outer surface of each product by the drive of the external air pump. After the sand removal is completed, the conveyor belt transports the material tray to the underside of the sand removal air knife 5 for another comprehensive sand removal process.

[0030] Through the continuous action of the first air blowing component 3, the second air blowing component 4, and each sand removal air knife 5, the sand inside the blind holes and on the outer surface of each product in the material tray is thoroughly removed. This effectively solves the problems of inefficiency caused by manual sand removal in the existing technology and residual sand on the sintered product. It greatly improves the sand removal efficiency of the product and the quality of the sintered product. The structure is ingenious, convenient and practical.

[0031] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
