Description

Technical Field

[0001] This utility model belongs to the technical field of sandblasting machines, and in particular relates to a sandblasting machine for stainless steel surface treatment. Background Technology

[0002] The working principle of a sandblasting machine is as follows: using compressed air as the main power, the high-speed movement of the airflow creates negative pressure inside the sandblasting gun. The abrasive is drawn into the sandblasting gun through the sand supply pipe and ejected through the nozzle, producing an impact and cutting action on the workpiece surface. This results in a certain degree of cleanliness and corresponding roughness on the workpiece surface, improving the mechanical properties of the workpiece surface, enhancing the workpiece's fatigue resistance, increasing the adhesion between the workpiece and the coating, improving the durability of the coating film, and also facilitating the leveling and decoration of the paint. At the same time, it roughens the surface of the medium, eliminates residual stress in the workpiece, and increases the surface hardness of the substrate.

[0003] Sandblasting is a common surface treatment method for stainless steel. Its main purpose is to improve the fatigue resistance of stainless steel, increase its adhesion to coatings, and provide a good base for coating, ensuring the coating film has good corrosion resistance and decorative properties. However, existing sandblasting machines for stainless steel surface treatment have low automation levels, requiring manual operation of the sandblasting gun. Furthermore, they cannot treat both sides of the stainless steel simultaneously, significantly reducing work efficiency and increasing the labor intensity for workers. Utility Model Content

[0004] The purpose of this utility model is to provide a sandblasting machine for stainless steel surface treatment, so as to solve the technical problems mentioned in the background art.

Reciprocating sandblasting assemblies are provided inside both the upper and lower protective covers. The reciprocating sandblasting assemblies are located on the upper and lower sides of the rollers. Each reciprocating sandblasting assembly includes a guide rail, with both ends of the guide rail fixedly connected to the inner wall of the protective cover. A slider is slidably connected to the guide rail, and a connecting rod is fixedly connected to one side wall of the slider. Multiple sandblasting guns are provided on the connecting rod along its length direction, and a driving mechanism is provided inside the protective cover for driving the slider to reciprocate along the length direction of the guide rail.

[0006] Preferably, a first motor connected to one of the roller shafts is mounted on one side of the frame, and the multiple rollers are connected by a belt drive mechanism.

[0007] Preferably, observation windows are provided on both the front and rear surfaces of the upper protective cover, and material inlets are provided at the bottom of both the left and right ends of the upper protective cover.

[0025] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a sandblasting machine for stainless steel surface treatment.

[0026] like Figure 1-3 As shown, the present invention discloses a sandblasting machine for stainless steel surface treatment, comprising a frame 1, on which a plurality of equally spaced rollers 3 are rotatably connected along the length of the frame 1 via bearings. A first motor 2 is installed on one side of the frame 1 and connected to the shaft of one of the rollers 3. The plurality of rollers 3 are connected to each other via a belt drive mechanism 4. Through the cooperation of the first motor 2 and the belt drive mechanism 4, the plurality of rollers 3 rotate simultaneously, thereby driving the stainless steel plate placed on the rollers 3 to move forward. In order to prevent the rollers 3 from scratching the stainless steel plate, the rollers 3 are coated with rubber.

[0027] The frame 1 is equipped with protective covers 5 on both the top and bottom sides. The protective covers 5 are hollow structures with open bottoms. The front and rear surfaces of the upper protective cover 5 are equipped with observation windows 6, and the bottom of the left and right ends of the upper protective cover 5 are equipped with material inlets 7. The stainless steel plate roller 3 moves forward and enters the interior of the protective cover 5 through the material inlets 7. The interior of the protective cover 5 can be observed through the observation windows 6, which isolates it from the outside world during sandblasting and has a good protective effect.

[0028] Both the upper and lower protective covers 5 are equipped with reciprocating sandblasting assemblies 18. The reciprocating sandblasting assemblies 18 are located on the upper and lower sides of the roller 3. The reciprocating sandblasting assemblies 18 include guide rails 10. The two ends of the guide rails 10 are fixedly connected to the inner wall of the protective cover 5. A slider 14 is slidably connected to the guide rails 10. A connecting rod 15 is fixedly connected to one side wall of the slider 14. Multiple sandblasting guns 16 are arranged at equal intervals along the length of the connecting rod 15. A driving mechanism for driving the slider 14 to reciprocate along the length of the guide rails 10 is provided inside the protective cover 5. The driving mechanism includes a second motor 9, with a first connecting rod 12 connected to the shaft of the second motor 9. The end of the first connecting rod 12 away from the second motor 9 is rotatably connected to a second connecting rod 13 via a rotating shaft. The end of the second connecting rod 13 away from the first connecting rod 12 is rotatably connected to the side wall of the slider 14 via a rotating shaft. A fixing plate 8 is provided at the bottom of the second motor 9, with both ends of the fixing plate 8 fixedly connected to the inner wall of the protective cover 5. The second motor 9 is installed in the middle of the fixing plate 8. By starting the second motor 9, the cooperation between the first connecting rod 12 and the second connecting rod 13 drives the slider 14 to move back and forth continuously along the length direction of the guide rail 10. This causes multiple sandblasting guns 16 to move back and forth along the length direction of the roller 3 along the connecting rod 15. This allows the upper and lower sets of sandblasting guns 16 to move back and forth continuously along the width direction of the stainless steel plate, thereby achieving uniform sandblasting treatment on the surface of the stainless steel plate and achieving double-sided sandblasting treatment in one go, greatly improving work efficiency. A limiting plate 11 is provided on the inner wall of the protective cover 5. A limiting groove 17 is provided in the middle part of the surface of the limiting plate 11 along its length direction. A limiting block is provided at the end of the connecting rod 15 away from the slider 14, which is slidably connected to the limiting groove 17. Through the cooperation between the limiting block and the limiting groove 17, the connecting rod 15 plays an auxiliary support role and makes the movement of the connecting rod 15 more stable and reliable. The fixing plate 8 is distributed parallel to the length direction of the guide rail 10 and the limiting plate 11. The length direction of the guide rail 10 is parallel to the length direction of the roller 3. The length direction of the connecting rod 15 is perpendicular to the length direction of the roller 3. Multiple sandblasting guns 16 are distributed along the length of the stainless steel plate. When they move back and forth, they move along the width direction of the stainless steel plate, which can effectively avoid the phenomenon of uneven sandblasting on the lower surface of the stainless steel plate due to the obstruction of the roller 3. A sandblasting material storage bin for feeding the sandblasting gun 16 is provided on the protective cover 5 or on one side of the frame 1. The feeding method is a mature existing technology and will not be described in detail here. The sandblasting gun 16 is connected to it through a hose, which will not interfere with the movement of the sandblasting gun 16.
