Description

Technical Field

[0001] This utility model belongs to the field of shot blasting machine technology, specifically relating to a roller conveyor type shot blasting machine. Background Technology

[0002] The roller conveyor shot blasting machine uses an electrically controlled adjustable speed conveyor roller to feed steel structural components or steel materials into the blasting zone inside the cleaning chamber. The components are subjected to strong and dense shot impacts and friction from different coordinate directions, causing the oxide scale, rust layer and dirt on the workpiece to be quickly removed, and the steel surface to obtain a smooth surface with a certain roughness. The workpieces are loaded and unloaded at the inlet and outlet roller conveyors on both sides of the cleaning chamber.

[0003] A roller conveyor shot blasting machine, as disclosed in utility model publication CN219617511U, includes a shot blasting frame. A conveying trough is positioned above the frame, and a conveying roller is installed inside the trough. A shot blasting chamber is positioned above the trough, and a cleaning chamber is located on one side of the chamber above the trough. A swing rod is positioned below one end of a fixed rod, and a rotating shaft connects the swing rod to the fixed rod. A scraping roller is installed at the end of the swing rod furthest from the fixed rod, and a compression spring connects the swing rod and the fixed rod on the side closest to the shot blasting chamber. The scraping roller at the end of the fixed rod enters the inner side of the grooved workpiece to scrape away any residual steel wire shot. The size of the scraping roller can be adjusted according to the required inner dimensions of the grooved workpiece.

[0004] The above-mentioned solution cannot limit and guide the workpiece input according to the outer contour size of the workpiece during the input process, making it inconvenient to move the workpiece accurately to the processing station. At the same time, it cannot position the workpiece during the cleaning process, and it is easy to cause wear on the workpiece surface when cleaning steel wire shot. Therefore, we propose a roller conveyor type shot blasting machine. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-2This utility model provides a technical solution: a roller conveyor type shot blasting machine, a shot blasting chamber 3 is provided on the upper mounting frame 7, a shot blasting machine frame 5 is provided on one side of the shot blasting chamber 3, a shot blasting storage box 4 is provided on the shot blasting machine frame 5, multiple sets of conveying rollers 6 are provided in the upper mounting frame 7 and a cleaning chamber 9 is provided on one side of the upper mounting frame 7, the upper mounting frame 7 is provided on the base frame 8, and a limiting mechanism 1 for positioning and guiding the workpiece is also provided on one side of the upper mounting frame 7;

[0026] The limiting mechanism 1 includes a bidirectional ball screw 16, which is rotatably mounted in a mounting groove 15. The mounting groove 15 is located on one side of the upper surface of the upper mounting frame 7. A first nut 14 and a second nut 17 are symmetrically arranged on both sides of the bidirectional ball screw 16. The first nut 14 is connected to a first positioning plate 11, and the second nut 17 is connected to a second positioning plate 18. Multiple sets of auxiliary guide structures 12 are provided on one side surface of both the first positioning plate 11 and the second positioning plate 18. One end of the bidirectional ball screw 16 is connected to the drive shaft of a drive motor 13. The drive motor 13 is located on one side surface of the upper mounting frame 7 and can control the rotation direction of the bidirectional ball screw 16.

[0027] When the conveying roller 6 conveys the workpiece, the bidirectional ball screw 16 can be rotated by the drive motor 13. The opposing movement of the first nut 14 and the second nut 17 drives the first positioning plate 11 and the second positioning rod to move in opposite directions, and makes the auxiliary guide structure 12 fit against the two sides of the workpiece, and guides the movement of the workpiece. When the workpiece moves into the shot blasting chamber 3, the auxiliary guide structure 12 moves into the first positioning plate 11 and the second positioning plate 18 through the continuous opposing movement of the first positioning plate 11 and the second positioning plate 18, and makes the first positioning plate 11 and the second positioning plate 18 clamp and fix the workpiece. Then the surface of the workpiece is cleaned by the shot blasting chamber 3.

[0028] Furthermore, a guide block is also provided on the other side of the bottom of the first positioning plate 11 and the second positioning plate 18. The guide block is slidably disposed in the guide groove, which is disposed on one side surface of the upper mounting bracket 7. When the first positioning plate 11 and the second positioning plate 18 move, the guide block can be driven to move in the guide groove, thereby improving the guiding performance of the first positioning plate 11 and the second positioning plate 18 when they move.

[0029] Please see Figure 3 The auxiliary guiding structure 12 includes a guide roller 122, which is rotatably mounted inside a bracket 121. The bracket 121 is mounted inside a groove 123, which is mounted on one side surface of the first positioning plate 11 and the second positioning plate 18, and can slide and guide the workpiece. A return spring 124 is also mounted on one side surface of the groove 123. One end of the return spring 124 is connected to the bracket 121, which can reset and move the bracket 121 inside the groove 123 and make the guide roller 122 fit against the surface of the workpiece.

[0030] When the first positioning plate 11 and the second positioning plate 18 move toward each other, they drive the guide roller 122 to move. When the guide roller 122 is in contact with the surface of the workpiece, the workpiece drives the guide roller 122 to rotate as the workpiece moves, and guides the movement of the workpiece. When the workpiece enters the shot blasting chamber 3, the stand moves in the tank 123 as the first positioning plate 11 and the second positioning plate 18 move toward each other, and compresses the return spring 124. When the first positioning plate 11 and the second positioning plate 18 are in contact with the surface of the workpiece, the surface of the workpiece is treated. After the treatment is completed, the first positioning plate 11 and the second positioning plate 18 are separated from the two sides of the workpiece and then conveyed to the cleaning chamber 9 by the conveying roller 6 for surface cleaning with steel wire shot.

[0031] Please see Figure 4 as well as Figure 5 The cleaning chamber 9 is also equipped with a high-pressure cleaning mechanism 2, which includes a high-pressure air pump 22. The high-pressure air pump 22 is installed inside the mounting box 21, which is located on one side surface of the cleaning chamber 9. The air outlet of the high-pressure air pump 22 is equipped with an air supply hose 24. One end of the air supply hose 24 is connected to a diversion pipe 25, which is located inside the cleaning chamber 9. The diversion pipe 25 is equipped with evenly spaced inclined nozzles 26, which can clean the attached steel wire shot.

[0032] When the workpiece enters the cleaning chamber 9, the high-pressure air pump 22 delivers high-pressure airflow to the air delivery hose 24, the air delivery hose 24 delivers the high-pressure airflow to the diversion pipe 25, the diversion pipe 25 delivers the high-pressure airflow to the nozzle 26, and the nozzle 26 sprays out the high-pressure air. The high-pressure airflow cleans the steel shot adhering to the surface of the workpiece, which solves the problem of scratches on the workpiece surface caused by the extrusion of the scraping roller in the prior art, and prevents the workpiece surface from being damaged.

[0033] Furthermore, a flexible shielding curtain 23 is also installed on one side of the cleaning chamber 9. It can automatically deform flexibly during the process of workpiece entering, and at the same time, it can shield the steel wire shot being cleaned to prevent the steel wire shot from splashing.

[0034] Furthermore, an electric push rod 27 is installed at the top of the cleaning chamber 9. One end of the piston rod of the electric push rod 27 is connected to the diversion pipe 25. By extending and retracting the electric push rod 27, the height of the diversion pipe 25 can be adjusted to meet the needs of cleaning steel shot adhering to the surface of workpieces of different heights.

[0035] Furthermore, a steel shot collection box 10 is also provided at the bottom of the upper mounting frame 7, which can collect steel wire shot in the shot blasting chamber 3 and the cleaning chamber 9.

[0036] The electric push rod 27, drive motor 13, and high-pressure air pump 22 in this application are all controlled by corresponding control switches.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
