Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a rust removal shot blasting machine with an adjustable angle shot blasting nozzle. Background Technology

[0002] A shot blasting machine is an industrial device that uses high-speed shot to clean or strengthen the surface of a workpiece. It accelerates the shot to high speed through a shot blaster and sprays it onto the surface of the workpiece to achieve the effects of removing rust, removing oxide scale, cleaning impurities, or increasing surface hardness. Shot blasting machines are widely used in casting, automotive, shipbuilding, and steel structure industries. For example, they are used to clean rough edges on castings and pre-treat steel surfaces to improve coating adhesion. Some shot blasting machines utilize centrifugal force for the shot blasting operation. For instance, Chinese utility model patent CN209110858U discloses a shot blasting machine. This application includes a conveying mechanism and a shot blasting mechanism. The shot blasting mechanism comprises a first housing, a first shot blasting port, a first shot inlet pipe, a first impeller, and a first rotating shaft (connected to a drive motor). The first shot blasting port is positioned along the tangential direction of the first housing, and the first shot inlet pipe is located within the housing. On one side of the body, multiple first impellers are evenly arranged on the first rotating shaft. Therefore, when performing shot blasting on different workpieces, and when the shot blasting angle of this application cannot be adjusted, for workpieces with complex shapes, such as parts with grooves or corners, a fixed shot blasting angle may not be able to fully cover all parts, resulting in incomplete rust removal in some areas. The non-adjustable shot blasting angle makes it difficult to flexibly adjust the shot blasting force and coverage according to the needs, which can easily cause over-blasting that damages the surface or under-blasting that fails to meet the rust removal standard, thus greatly limiting the adaptability of the shot blasting machine to diverse workpieces. Utility Model Content

[0003] The purpose of this invention is to provide a rust removal shot blasting machine with an adjustable angle shot blasting nozzle. The shot blasting angle can be adjusted by adjusting components such as the lead screw and guide shaft to adapt to different workpieces, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rust removal shot blasting machine with an adjustable angle shot blasting nozzle includes a rust removal box. One side of the rust removal box has a feed inlet, and the other side has a discharge outlet. Multiple carrier plates are fixedly connected to the outside of the rust removal box. A motor is fixedly connected to each carrier plate and electrically connected to an external main controller via a cable. A shot blasting mechanism is arranged on the carrier plate near the motor. The shot blasting mechanism includes a first base plate and a shot blasting box. The first base plate is fixedly connected to the carrier plate, and multiple positioning seats are fixedly connected to the first base plate. A first shaft seat is fixedly connected to one side of each positioning seat. A second base plate is fixedly connected to the bottom of the shot blasting box. Second shaft seats are fixedly connected to both sides of the shot blasting box and the second base plate. A first rotating shaft is rotatably connected within each second shaft seat. An adjusting screw is movably connected between one of the first rotating shafts and one of the first shaft seats, and a guide shaft is movably connected between the other second shaft seat and the other first shaft seat.

[0005] As a further preferred embodiment of this utility model, a guide groove is provided in the first base plate to connect the shot blasting box and the carrier plate, and to connect the channels in the shot blasting box and the rust removal box.

[0006] As a further preferred embodiment of this utility model, fixed rails are fixedly connected to both sides of the positioning seat, and multiple ball bearings are rotatably connected in the fixed rails, which allows the bottom of the shot blasting box to move axially between the two positioning seats, thereby realizing the adjustment of the installation angle of the shot blasting box. Sliding grooves are provided on both sides of the first shaft seat to provide installation and offset conditions for the second or third rotating shaft.

[0007] As a further preferred embodiment of this utility model, one end of the adjusting screw is rotatably connected to a second rotating shaft, and both ends of the second rotating shaft are slidably connected in corresponding grooves. One end of the guide shaft is fixedly connected to a third rotating shaft, and both ends of the third rotating shaft are also slidably connected in corresponding grooves. The adjusting screw, as an active adjusting component, can cooperate with the guide shaft to realize the angle adjustment operation of the shot blasting box on the first base plate.

[0008] As a further preferred embodiment of this utility model, the end of the adjusting screw away from the second rotating shaft is threadedly connected to one of the first rotating shafts, and the end of the guide shaft away from the third rotating shaft is inserted into another first rotating shaft and limited by a nut. By threading one end of the adjusting screw into the first rotating shaft, the adjusting screw can be adaptively deflected when the shot blasting box rotates.

[0009] As a further preferred embodiment of this utility model, a rotating wheel is rotatably connected inside the shot blasting box. One end of the rotating wheel is connected to the pulley at the output end of the carrier plate via a belt. Multiple shot blasting plates are fixedly connected to the rotating wheel inside the shot blasting box. The steel shot input into the shot blasting box can be thrown into the rust removal box by the centrifugal force generated when the shot blasting plates rotate. Arc-shaped connecting plates are fixedly connected to both sides of the bottom of the shot blasting box. Guide grooves are opened on both sides of the arc-shaped connecting plates. The arc-shaped connecting plates are inserted into the guide grooves and rotatably connected between two positioning seats. The guide grooves are slidably connected to the corresponding fixed rails. The connecting extension line of the two arc-shaped connecting plates is circular, and the center point of the connecting extension line of the two arc-shaped connecting plates is the same as the center point of the rotating wheel. This allows the angle of the shot blasting box to be adjusted, thereby achieving the throwing angle of the shot blasting plates on the steel shot.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the shot blasting angle is adjustable by means of adjusting screws, guide shafts, and other structures, effectively solving the drawbacks of fixed-angle shot blasting machines. During adjustment, rotating the adjusting screw, in conjunction with the guide shaft, slide groove, fixed rail, and other components, can drive the shot blasting box to flexibly adjust the angle. When facing complex workpieces with grooves, the shot can fully cover all areas to ensure thorough rust removal. For workpieces with special surface requirements, the shot blasting force and range can also be precisely controlled to avoid over-blasting that damages the surface or under-blasting that fails to meet standards, greatly improving the adaptability to diverse workpieces.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-5 As shown, this utility model provides a rust removal shot blasting machine with an adjustable angle shot blasting nozzle, including a rust removal box 1. One side of the rust removal box 1 has a feed inlet 2, and the other side has a discharge outlet 3. Multiple carrier plates 4 are fixedly connected to the outside of the rust removal box 1. Motors 5 are fixedly connected to the carrier plates 4, and the motors 5 are electrically connected to an external main controller via cables. A shot blasting mechanism 6 is arranged on the carrier plates 4 near the motors 5. The shot blasting mechanism 6 includes a first base plate 7 and a shot blasting box 8. The first base plate 7 is fixedly connected to the carrier plates 4. Multiple positioning seats 9 are fixedly connected to a base plate 7. A first shaft seat 10 is fixedly connected to one side of the positioning seat 9. A second base plate 13 is fixedly connected to the bottom of the shot blasting box 8. Second shaft seats 14 are fixedly connected between both sides of the shot blasting box 8 and the second base plate 13. A first rotating shaft 15 is rotatably connected inside the second shaft seat 14. An adjusting screw 11 is movably connected between one of the first rotating shafts 15 and one of the first shaft seats 10. A guide shaft 12 is movably connected between the other second shaft seat 14 and the other first shaft seat 10.

[0015] like Figures 2-4 As shown, a guide groove 16 is provided in the first base plate 7 to connect the shot blasting box 8 with the carrier plate 4 and to connect the shot blasting box 8 with the channel in the rust removal box 1. Fixed rails 17 are fixedly connected to both sides of the positioning seat 9. Multiple balls 18 are rotatably connected in the fixed rails 17, which allows the bottom of the shot blasting box 8 to move axially between the two positioning seats 9, thereby adjusting the installation angle of the shot blasting box 8. Slide grooves 19 are provided on both sides of the first shaft seat 10 to provide installation and offset conditions for the second rotating shaft 23 or the third rotating shaft 24. One end of the adjusting screw 11 is rotatably connected to the second rotating shaft 23, and both ends of the second rotating shaft 23 are slidably connected in the corresponding slide grooves 19. One end of the guide shaft 12 is fixedly connected to the third rotating shaft 24, and both ends of the third rotating shaft 24 are also slidably connected in the corresponding slide grooves 19. The adjusting screw 11, as an active adjusting component, can cooperate with the guide shaft 12 to realize the angle adjustment operation of the shot blasting box 8 on the first base plate 7. The end of the adjusting screw 11 away from the second rotating shaft 23 is threadedly connected to one of the first rotating shafts 15, and the end of the guide shaft 12 away from the third rotating shaft 24 is inserted into the other first rotating shaft 15 and limited by a nut. By threading one end of the adjusting screw 11 into the first rotating shaft 15, the adjusting screw 11 can be adaptively deflected when the shot blasting box 8 rotates.

[0016] like Figure 2 , Figure 5As shown, a rotating wheel 21 is rotatably connected inside the shot blasting box 8. One end of the rotating wheel 21 is connected to the pulley at the output end of the carrier plate 4 via a belt. Multiple shot blasting plates 22 are fixedly connected to the rotating wheel 21 inside the shot blasting box 8. The steel shot input into the shot blasting box 8 can be thrown into the rust removal box 1 by the centrifugal force generated when the shot blasting plates 22 rotate. Arc-shaped connecting plates 20 are fixedly connected to both sides of the bottom of the shot blasting box 8. Guide grooves 26 are opened on both sides of the arc-shaped connecting plates 20. The arc-shaped connecting plates 20 are inserted into the guide grooves 16 and rotatably connected between two positioning seats 9. The guide grooves 26 are slidably connected to the corresponding fixed rails 17. The connecting extension line of the two arc-shaped connecting plates 20 is circular, and the center point of the connecting extension line of the two arc-shaped connecting plates 20 is the same as the center point of the rotating wheel 21. The angle of the shot blasting box 8 can be adjusted to achieve the throwing angle of the shot blasting plates 22 on the steel shot.

[0017] It should be noted that this utility model is a rust removal shot blasting machine with an adjustable angle shot blasting nozzle. When using this shot blasting machine, the workpiece to be rusted is first fed into the rust removal box 1 through the feed port 2. Then, the internal conveying structure ensures that the workpiece moves stably within the rust removal box 1. Subsequently, the external main controller starts the motor 5 on the carrier plate 4. After the motor 5 starts, the pulley at the output end of the motor 5 drives the pulley at one end of the rotating wheel 21 inside the shot blasting box 8 to rotate via a belt, thereby causing the rotating wheel 21 to rotate within the shot blasting box 8. Multiple shot blasting nozzles fixed on the rotating wheel 21... Plate 22 rotates together with the rotating wheel 21. When the steel shot is continuously fed into the shot blasting box 8 through the external conveying mechanism, the centrifugal force generated by the rotation of the shot blasting plate 22 will throw the steel shot out at high speed. The steel shot enters the rust removal box 1 through the channel connecting the shot blasting box 8 and the rust removal box 1, impacting the surface of the workpiece inside to achieve the effect of rust removal and oxide scale removal. The workpiece that has completed rust removal is finally sent out from the discharge port 3 of the rust removal box 1. The steel shot that has completed the rust removal function is recycled and cleaned through the recycling mechanism at the bottom of the rust removal box 1, and then recycled back into the shot blasting box 8. When the shot blasting angle needs to be adjusted for different workpieces, the adjusting screw 11 can be operated. When the adjusting screw 11 is rotated, one end of the adjusting screw 11 is threadedly connected to the first rotating shaft 15, and the other end is rotatably connected to the second rotating shaft 23 and slides in the groove 19 in the first shaft seat 10. One end of the guide shaft 12 is slidably connected to the groove 19 through the third rotating shaft 24, and the other end is inserted into another first rotating shaft 15 and limited by a nut. With the support of the compression spring 25 on the outside of the guide shaft 12, the arc-shaped connecting plates 20 on both sides of the bottom of the shot blasting box 8 can rotate in the guide groove 16 of the first base plate 7. The guide grooves 26 on both sides of the arc-shaped connecting plates 20 slide along the fixed rail 17 in the positioning seat 9. The ball bearings 18 in the fixed rail 17 can reduce sliding friction, allowing the shot blasting box 8 to adjust the angle more smoothly. After the angle of the shot blasting box 8 changes, the direction of the shot ejected by the shot blasting plate 22 changes accordingly, thereby realizing the flexible adjustment of the shot blasting angle to adapt to workpieces with different shapes and surface requirements.
