DETAILED DESCRIPTION

[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] This utility model provides a sandblasting device for surface treatment of rolling mill castings, such as... Figures 1-5 As shown, the sandblasting device includes a box 1 with an open top. A roller 2 is rotatably connected inside the box 1. A motor 3 for driving the roller 2 is installed on the outer wall of the box 1. A roller column 4 is fixedly connected to the outer surface of the roller 2. A sandblasting head 7 is installed inside the box 1. A slide rod 6 is fixedly connected to the top of the sandblasting head 7. An arc-shaped groove 5 for the slide rod 6 to slide is opened on the outer surface of the roller column 4. A first gear 8 is fixedly connected to the end of the roller 2 away from the motor 3. A surrounding plate 10 is installed inside the box 1. A rotating rod 9 is fixedly connected inside the surrounding plate 10. The end of the rotating rod 9 away from the surrounding plate 10 is rotatably connected to the inside of the box 1. An electric push rod 11 is fixedly connected to the end of the rotating rod 9 away from the box 1. A positioning block 12 is fixedly connected to the movable end of the electric push rod 11. A second gear 13 that meshes with the first gear 8 is fixedly connected to the outer surface of the rotating rod 9.

[0026] Motor 3 enables roller 2 to rotate. When motor 3 is running, the output shaft drives roller 2 to rotate. When roller 2 drives roller 4 to rotate, roller 4 utilizes the surrounding arc-shaped groove 5 on its surface to cause slide rod 6 to be rotated and squeezed within the arc-shaped groove 5, thus smoothly reciprocating. This allows slide rod 6 to drive sandblasting head 7 to move left and right repeatedly, thereby increasing the sandblasting area of ​​sandblasting head 7 and performing large-scale sandblasting treatment on the roll casting. Furthermore, roller 2 can drive the first gear 8 to rotate synchronously, causing the second gear meshing with the first gear 8 to rotate synchronously. Gear 13 drives the rotating rod 9 to rotate, causing the rotating rod 9 to drive the positioning block 12 to flip via the electric push rod 11. This allows the roll castings inside the two positioning blocks 12 to be flipped and subjected to more comprehensive sandblasting treatment. The electric push rod 11 also enables the positioning blocks 12 to move, so that the two electric push rods 11 can drive the positioning blocks 12 to move closer to each other. This achieves the purpose of fixing the roll castings in place, preventing them from falling during the flipping process. It also provides a fixed point for the roll castings, making it easier for the sandblasting head 7 to perform sandblasting treatment.

[0027] The inner cavity of the sandblasting head 7 is connected to a flexible hose 14, and a storage box 15 is fixedly connected to the outer wall of the housing 1. The end of the flexible hose 14 away from the sandblasting head 7 is connected to the inner cavity of the storage box 15, and an opening and closing valve 16 is provided on the flexible hose 14.

[0028] The on-off valve 16 enables the hose 14 to smoothly introduce the sand particles in the box 1 into the sand blasting head 7, so that the sand blasting head 7 can perform sand blasting on the roller casting, and the hose 14 provides a flow space between the sand particles and the sand blasting head 7, and the storage box 15 provides a storage space for the sand particles, facilitating the hose 14 to introduce the sand particles into the sand blasting head 7 for blasting.

[0029] The inside of the box 1 is fixedly connected with a connecting plate 17, and the outer surface of the slide rod 6 is fixedly connected with a limiting block 18 which is overlapped on the top of the connecting plate 17, and the inside of the connecting plate 17 is provided with a through hole 19 for the slide rod 6 to slide.

[0030] The limiting block 18 overlaps with the connecting plate 17 to provide good stability for the slide rod 6, preventing the slide rod 6 from directly falling in the arc-shaped groove 5, thereby ensuring the stability of the sand blasting head 7 when moving, and the through hole 19 provides a moving space for the slide rod 6, preventing the slide rod 6 from being blocked by the connecting plate 17 and moving smoothly, and the through hole 19 provides good stability for the slide rod 6 when moving, preventing the slide rod 6 from deviating when moving, etc.

[0031] The bottom of the box 1 is fixedly connected with a discharge port 20, and the discharge port 20 is provided with an on-off valve 21.

[0032] The discharge port 20 provides a space for the sand particles in the box 1 to be discharged outward, so that the sand particles remaining after the sand blasting head 7 performs sand blasting on the roller casting can be discharged outward, facilitating the next use, and the on-off valve 21 enables the discharge port 20 to be opened or closed, preventing the sand particles in the box 1 from leaking through the discharge port 20 directly according to the discharge requirement.

[0033] The inside of the fence 10 is slidably connected with a baffle 22 for shielding the electric push rod 11, and the bottom of the box 1 is fixedly connected with a supporting leg 23.

[0034] The baffle 22 is provided to reduce the area of the electric push rod 11 exposed in the working area when the sand blasting process is performed, so that the electric push rod 11 is not easily covered by the sand particles, thereby improving the service life of the electric push rod 11.

[0035] Working principle:

[0036] When the sand blasting work needs to be carried out on the roller casting, first, the two electric push rods 11 are used to drive the positioning blocks 12 to realize mutual approaching to fix the roller casting, then the on-off valve 16 is used to make the sand particles in the storage box 15 introduced into the sand blasting head 7 through the hose 14 to be sprayed out, so as to achieve the purpose of sand blasting treatment on the positioned roller casting, at this time, the motor 3 is started, so that the output shaft of the motor 3 drives the roller shaft 2 to rotate, so that when the roller shaft 2 drives the roller column 4 to rotate, the slide rod 6 slides along the arc-shaped slot 5 on the roller column 4, thereby driving the sand blasting head 7 to reciprocate, so as to improve the sand blasting area of the sand blasting head 7, and the roller shaft 2 can drive the first gear 8 to rotate synchronously, so that the second gear 13 engaged with the first gear 8 can drive the rotating rod 9 to rotate, so that the rotating rod 9 can drive the positioning blocks 12 to rotate through the electric push rod 11, so that the roller castings in the two positioning blocks 12 can be turned over, so that the roller castings can be subjected to comprehensive sand blasting treatment.

[0037] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
