Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting devices, in particular to a part surface sandblasting device. Background Art

[0002] Due to the impact and cutting effect of abrasives on the surface of parts, the sandblasting machine makes the surface of parts obtain a certain degree of cleanliness and different degrees of roughness, so that the mechanical properties of the surface of parts are improved, which is convenient for subsequent processing of the surface of parts.

[0003] When using an existing sandblasting machine, a conveyor belt is generally used to transport parts to a sandblasting box, and a sand material is sprayed onto the surface of the parts through a spray gun to process the parts. Since the sandblasting gun is generally only set above the parts, only the side of the parts close to the sandblasting gun can be fully processed, which is inconvenient and has a poor use effect. In addition, when using some handheld sandblasting guns, the staff needs to hold the parts for sandblasting. After the parts are sandblasted, they need to be taken out of the box before sandblasting can be performed on another part, which is slow. To this end, we propose a part surface sandblasting device.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a part surface sandblasting device, comprising a box body 1, two pairs of mounting plates 2 are symmetrically installed inside the box body 1, and the ends of the two pairs of mounting plates 2 that are far away from each other are both extended out of the box body 1, a mesh belt conveyor is arranged between one pair of mounting plates 2, and a roller conveyor is arranged between the other pair of mounting plates 2. The parts to be sandblasted can be conveyed into the box body 1 for sandblasting by the mesh belt conveyor, and can be moved out of the box body 1 by the roller conveyor after sandblasting, so that sandblasting is convenient.

[0025] like Figure 2 As shown, two fixed plates 16 are installed inside the box 1, one of which is located above the mesh belt conveyor, and the other is located below the roller conveyor. Several spray guns 7 are evenly installed on each fixed plate 16. The air inlet of the spray gun 7 is connected to an air inlet pipe 8, and the other end of the air inlet pipe 8 passes through the box 1 and is connected to an external air compressor. The sand inlet of the spray gun 7 is connected to a feed pipe 9, and the other end of the feed pipe 9 passes through the box 1 and is connected to an external material box. When the parts are moved into the box 1, the parts can be moved to the bottom of the spray gun 7 under the action of the mesh belt conveyor, and the top of the parts are sandblasted by the spray gun 7, and then they are transported to the roller conveyor, and then the parts follow the roller conveyor to move to the top of the spray gun 7, and the bottom of the parts are sandblasted by the spray gun 7, and the sandblasting is sufficient to improve the use effect.

[0026] like Figure 1 and Figure 3As shown, an electric push rod 10 is installed at one end of the top of the box 1, and the bottom of the electric push rod 10 passes through the box 1 and is connected to a U-shaped frame 11 with an opening downward. A plurality of rollers 17 are equidistantly connected to the U-shaped frame 11, and the rollers 17 are located above the roller conveyor. The electric push rod 10 can push the U-shaped frame 11 downward so that the rollers 17 can contact the parts, thereby preventing the parts from falling off the roller conveyor when the bottom of the parts is sandblasted.

[0027] Specifically, when the utility model is in use, the electric push rod 10 is controlled to work, and the electric push rod 10 pushes the U-shaped frame 11 to move downward. The distance between the pressure roller 17 and the roller conveyor is adjusted according to the height of the parts, and then the parts to be processed are placed on the mesh belt conveyor and transported to the box 1 through the mesh belt conveying mechanism. When the parts pass under the spray gun 7, the sand sprayed by the spray gun 7 can process the upper surface of the parts, and then the parts can be moved to the roller conveyor, and the top of the parts contacts the pressure roller 17. The roller conveyor drives the parts to move. When the parts pass above the spray gun 7, the sand sprayed by the spray gun 7 can process the bottom of the parts. After sufficient processing, the processed parts are transported to the outside of the box 1 through the rolling conveyor.

[0028] Further, such as Figure 1 and Figure 4 As shown, the mesh belt conveyor includes support shafts 4 that are equidistantly connected to each other in rotation, and the support shafts 4 are connected by conveyor belts 3, and the conveyor belts 3 are mesh belts. The first sprockets 19 are coaxially installed at both ends of each support shaft 4, and the two sides of the conveyor belt 3 are connected to the first sprockets 19 through chains. The end of the support shaft 4 located at one end of the mounting plate 2 is connected to the first motor 5, and the first motor 5 is fixed on the mounting plate 2. The first motor 5 can drive the support shaft 4 to rotate, thereby controlling the movement of the conveyor belt 3, and the parts placed on the conveyor belt 3 are moved into the box 1 for sandblasting, which is convenient for processing.

[0029] Further, such as Figure 4 As shown, the roller conveyor includes rotating rollers 6 that are equidistantly connected between another pair of mounting plates 2, and the top nozzle of the spray gun 7 located below the roller conveyor extends between two adjacent rotating rollers 6, and the second sprockets 20 are coaxially mounted at both ends of each rotating roller 6, and the second sprockets 20 are connected by chains, and the end of the rotating roller 6 located at one end of the mounting plate 2 is connected to a second motor 21, and the second motor 21 is fixed on the mounting plate 2. The second motor 21 can drive the rotating roller 6 to rotate under the action of the second sprocket 20 and the chain, and the parts falling on the rotating roller 6 are conveyed out of the box 1, and the staff can remove the parts on the rotating roller 6.

[0030] Further, such as Figure 2As shown, the bottom of the box body 1 is connected to a collecting hopper 13, the bottom of the collecting hopper 13 is connected to an external material box through a pipeline, and guide plates 14 are installed at both ends of the top of the collecting hopper 13. The guide plates 14 are inclined, and the top of each guide plate 14 is fixed to the bottom of the mounting plate 2. Part of the sand material sprayed during the sandblasting process can directly fall into the collecting hopper 13, and part of the sand material can fall into the collecting hopper 13 along the guide plates 14, and be transported to the material box through the pipeline for recycling.

[0031] Further, such as Figure 1 As shown, a blocking plate 15 is installed at one end of the mounting plate 2 close to the roller conveyor, and the bottom of the blocking plate 15 is fixed on the top of the guide plate 14. When the staff takes the sandblasted parts, they can shake the parts to shake off the sand remaining on the parts. The blocking plate 15 can block the sand to prevent it from falling into the surrounding environment.

[0032] Further, such as Figure 1 As shown, guide rods 12 are installed at the top corners of the U-shaped frame 11, and the top of each guide rod 12 slides through the box body 1. The U-shaped frame 11 can be guided by the guide rods 12, so that the U-shaped frame 11 remains stable.

[0033] Furthermore, if Figure 2 As shown, a filter plate 18 is installed at the inner top of the collecting hopper 13, and the filter plate 18 is located below the bottom end of the guide plate 14. The sand material after sandblasting can be filtered through the filter plate 18 to filter out impurities in the sand material.
