Technical Field

[0001] This utility model relates to the field of sandblasting machines, and in particular to a manual sandblasting machine. Background Technology

[0002] Automotive parts are diverse, and after processing, they require sandblasting to improve their appearance, performance, and lifespan, providing a good foundation for subsequent coating treatments. Existing sandblasting machines, especially manual ones, typically involve manual feeding and unloading. After sandblasting one workpiece, the operator must remove themselves from the manhole, open the machine door, remove the finished workpiece, and then place the next workpiece into the sandblasting chamber before resuming the process. This lack of continuity in the process reduces efficiency, and the repeated opening and closing of the chamber allows dust to escape, polluting the environment and posing a health risk to operators. Summary of the Invention

[0022] Example 1:

[0023] like Figures 1 to 3 As shown, this utility model provides a manual sandblasting machine, including a support frame 1, a sandblasting box 2, an operating handhole 3, an observation window 4, a fixed box 6, a partition 7, a retrieval chamber 8, a partition chamber 9, an opening 10, a conveying port 11, and a conveying plate 20; the sandblasting box 2 is locked and fixed to the top surface of the support frame 1; a transparent observation window 4 is fixedly embedded in the top of the front surface of the sandblasting box 2.

[0024] Two operating hand holes 3 are provided on the front face of the sandblasting box 2. Gloves to protect the operator's hands are provided in the operating hand holes 3 but are not shown in the figure.

[0025] The fixed box 6 is embedded in the left end face of the sandblasting box 2; the partition 7 is vertically locked and fixed inside the fixed box 6, and the partition 7 divides the left and right ends of the inner side of the fixed box 6 into the retrieval chamber 8 and the partition chamber 9; the opening 10 passes through the left and right ends of the fixed box 6, and the opening 10 at the right end is connected to the inner side of the fixed box 6; the conveying port 11 is opened on the partition 7, and the conveying port 11 is aligned with the inner side of the opening 10.

[0026] A circular conveyor plate 20 is rotatably installed inside the fixed box 6. The conveyor plate 20 moves through the inside of the conveying port 11. Several through holes are opened on the top surface of the conveyor plate 20. The through holes are connected to the bottom of the inner side of the fixed box 6, so that the sand material remaining on the workpiece conveyed on the conveyor plate 20 can be discharged outward through the through holes. A motor for driving the horizontal rotation of the conveyor plate 20 is provided below the fixed box 6 (not shown in the figure).

[0027] The fixed box 6 is provided with a sealing assembly, which includes a connecting frame 12 locked and fixed to the right end face of the fixed box 6, a first telescopic cylinder 13 installed on the connecting frame 12, and a sealing plate 14 detachably installed on the piston rod of the first telescopic cylinder 13 and movably connected to the fixed box 6. When the piston rod of the first telescopic cylinder 13 is fully extended, the sealing plate 14 completely covers the opening 10 at the right end. The first telescopic cylinder 13 is a cylinder.

[0028] In this embodiment, in order to facilitate the inspection and maintenance of the inside of the sandblasting box 2, and also to facilitate the placement of workpieces inside the sandblasting box 2, a box door 5 is hinged to the right end of the sandblasting box 2.

[0029] In this embodiment, a sealing assembly is also provided on the partition 7. The sealing assembly also includes a connecting frame 12, a first telescopic cylinder 13, and a sealing plate 14. The connecting frame 12 is installed on the partition 7, and the sealing plate 14 is movably connected to the partition 7. When the piston rod of the first telescopic cylinder 13 is in the fully extended state, the sealing plate 14 completely covers the conveying port 11, and at this time the sealing plate 14 is in contact with the top surface of the conveying plate 20, further improving the sealing performance of the sandblasting box 2 and reducing the outward flow of dust.

[0030] Specifically, the first telescopic cylinder 13 is connected to an external pneumatic device. The pneumatic device and the sandblasting machine are connected to the controller via a control cable. The operator can put their hand through the operating hand hole 3 and into the pre-set glove in the operating hand hole 3. Another operator puts the workpiece to be processed onto the conveyor plate 20 in the retrieval chamber 8. By activating the two first cylinders 13, the first cylinders 13 drive the sealing plate 14 to move upward, thereby opening the opening 10 and the conveying hole 11. At this time, the motor drives the conveyor plate 20 to rotate, and the conveyor plate 20 carries the workpiece through the conveying hole 11. The operator can take the workpiece off the conveyor plate 20 through the opening 10 and control the two first telescopic cylinders 13 to drive the sealing plate 14 to move downward to close the opening 10 and the conveying hole 11.

[0031] At this time, the operator holds a sandblasting gun in one hand and a workpiece in the other to perform sandblasting on the workpiece. During the operation, the external worker puts the next workpiece into the top left end of the conveyor plate 20. After the sandblasting is completed, the first cylinder 13 drives the sealing plate 14 to move upward again, opening the opening 10 and the conveying hole 11. The operator then places the processed workpiece on the top left end of the conveyor plate 20. When the conveyor plate 20 rotates, the unprocessed and processed workpieces are swapped. The external worker takes out the processed workpiece, while the operator continues to take out the unprocessed workpiece on the right end for sandblasting.

[0032] Example 2:

[0033] like Figure 4 As shown, in this embodiment, a pushing component is also provided inside the fixed box 6. The pushing component includes a tray 17 installed inside the fixed box 6, a second telescopic cylinder 18 installed on the tray 17, and a push plate 19 installed on the piston rod of the second telescopic cylinder 18. The tray 17 is located inside the partition chamber 9, and the push plate 19 is directly opposite the opening 10 at the right end. The second telescopic cylinder 18 is a cylinder.

[0034] The bottom end face of the pallet 17 and the top end face of the conveyor plate 20 are provided with a gap to facilitate the movement and conveying of the workpiece at the bottom of the pallet 17.

[0035] The outer surface of the push plate 19 and the side surface of the conveyor plate 20 are spaced apart to facilitate the conveyor plate 20 to move the workpiece to the right end of the push plate 19.

[0036] Among them, the sealing plate 14 is equipped with a roller 15, which is rolledly connected to the inner side of the roller groove 16 opened on the fixed box 6. The roller 15 and the roller groove 16 provide positioning for the sealing plate 14, thereby improving the stability of the sealing plate 14 during movement.

[0037] Specifically, when the unprocessed workpiece moves to the top right end of the conveyor plate 20, the push plate 19 can be moved to the right by controlling the second telescopic cylinder 18, so that the push plate 19 pushes the unprocessed workpiece into the sandblasting box 2, so that the operator can quickly get the unprocessed workpiece.
