Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to an automatic sandblasting machine with an automatic feeding function. Background Art

[0002] The core operating principle of a sandblaster is to use a high-speed jet of abrasive to impact and cut the workpiece surface, thereby achieving surface cleaning, surface modification, and decorative effects. Its operation involves several key components: the power source, abrasive supply, and spray gun. The power source is typically compressed air, which forms a high-speed airflow within the spray gun. The abrasive supply system is responsible for delivering the abrasive to the spray gun, where it mixes with the high-speed airflow. When the mixed abrasive stream is ejected from the spray gun nozzle, it impacts the workpiece surface at a high velocity. Due to the hardness and sharpness of the abrasive, the impact generates impact and cutting forces on the workpiece surface. These impact and cutting forces can remove impurities such as rust, scale, oil, and old coatings from the workpiece surface, while also changing the microgeometry of the workpiece surface, increasing surface roughness or achieving a specific surface texture.

[0003] Chinese patent CN218226153U discloses a feeding mechanism of a diamond composite tool sandblasting machine, including a sandblasting machine body and a support column, wherein one side of the outside of the sandblasting machine body is fixedly connected to a fixing frame, one side of the outside of the fixing frame is installed with a rotating motor, one side of the output end of the rotating motor is fixedly connected to a bevel gear, one end of the outside of the rotating motor is connected to a screw rod through a bevel gear, and the outside of the screw rod is spirally driven with a No. 2 sleeve block, which is driven by the rotating motor to rotate the bevel gear, thereby synchronously driving the screw rod to rotate, so that the No. 2 sleeve block can be linearly moved up and down, which is convenient for the placement plate to drive the tool to load, bringing convenience to the staff when loading tools with large volume and mass, and also greatly saving physical energy consumption. At the same time, a number of rollers are rotatably connected between the corresponding sides of the inner wall of the placement plate through bearings, which can effectively reduce the friction resistance generated by the tool when moving.

[0027] In this embodiment, the recovery conveying mechanism includes two parallel slide rails 29, which are fixedly connected to the support frame 2. A second conveyor 10 is provided below the two slide rails 29. A plurality of second push rods 11 are evenly distributed on the conveyor belt of the second conveyor 10 along the extension direction of the conveyor belt. The second push rod 11 includes an upper half 11-1 and a lower half 11-2. The lower half 11-2 is fixedly connected to the conveyor belt.

The upper half 11-1 is bent in the opposite direction of the movement direction of the conveyor belt of the recovery conveyor.

[0028] In this embodiment, the loading mechanism includes a frame 12, in which a platform 13 is vertically slidably provided inside the frame 12, a slide rail 3 14 is provided above the platform 13 and is connected to the slide rail 1 5 and the slide rail 2 9, and a lifting mechanism 15 is provided below the platform 13.

[0030] In this embodiment, the lifting mechanism 15 is a hydraulic cylinder lifter, and the telescopic push rod 19 and the telescopic push rod 23 are electrically controlled push rods.

[0031] In this embodiment, both frame 1 12 and frame 2 20 are provided with a control panel for controlling the operation of the lifting mechanism 15 and the telescopic push rod 1 19 and the telescopic push rod 2 23 .

[0032] The working principle and beneficial effects of the above technical solution are:

[0033] When in use, the first step is to open the sandblasting machine body 1 for sandblasting operation and open the first conveyor 6 and the second conveyor 10; the second step is to lift the carrier 13 and the carrier 2 21 so that the slide rail 3 14 and the slide rail 4 22 are aligned with the slide rail 1 5, and the workpiece is placed on the pallet 8 on the carrier 13 and fixed with the fixture; the third step is to control the extension of the telescopic push rod 19 through the control panel to push the workpiece together with the pallet 8 to the slide rail 5. As the conveyor belt on the first conveyor 6 moves, the first push rod 7 contacts the cross bar 8-2 at the bottom of the pallet 8, thereby pushing the pallet 8 to move into the sandblasting machine body 1 for sandblasting operation, and then the pallet 8 is pushed onto the carrier 2 21; the fifth step is to remove the workpiece and control the lifting and lowering of the bottom of the carrier 2 21 through the control panel. The mechanism 15 contracts, so that the slide rail four 22 is aligned with the slide rail two 9, and then the telescopic push rod two 23 is controlled to extend to push the pallet 8 onto the second conveyor 10. At this time, the pallet 8 slides on the slide rail two 9. When the pallet 8 moves to the end of the second conveyor 10 close to the frame one 12, the pallet 8 stops moving under the obstruction of the baffle 18. Under the action of the thrust, the upper half 11-1 of the second push rod 11 is bent so that the thrust contacts the pallet 8, and then continues to follow the movement of the conveyor belt. When loading is required, the platform one 13 is lowered through the control panel. When the slide rail three 14 is aligned with the slide rail two 9, the baffle 18 is compressed into the storage slot. Under the action of the second push rod 11, the pallet 8 is pushed onto the platform one 13, and then the platform one 13 is lifted to the upper end of the frame one 12, thereby repeating the above process.

[0034] Compared with the existing technology, the utility model completes the recycling of pallets 8 and tooling through the arrangement of the first conveyor 6 and the second conveyor 10, thereby reducing the labor intensity of manually carrying pallets 8 and tooling fixtures back and forth, improving work efficiency, reducing the storage quantity of materials such as pallets 8 and tooling fixtures, reducing costs, and solving the deficiency of the existing automatic loading sandblasting machine that can only perform a single lifting operation function.

[0035] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
