Description

A mirror-finish roll sandblasting equipment Technical Field

[0001] This utility model relates to the technical field of mirror roll surface treatment equipment, specifically to a mirror roll sandblasting equipment. Background Technology

[0002] Stainless steel strip is simply an extension of ultra-thin stainless steel sheet. It is a narrow and long steel plate mainly produced to meet the needs of various industrial sectors for the industrial production of various metal or mechanical products. Its surface is relatively smooth and can form a mirror effect, hence it is also called mirror roll. During the processing of mirror roll, the surface needs to be sandblasted by sandblasting equipment to improve the surface matte effect.

[0003] Existing mirror roll sandblasting equipment uses a pump to extract sandblasting particles, creating a high-speed airflow that is then sprayed onto the surface of a conveyed mirror roll. However, this method suffers from several drawbacks. Since mirror rolls come in various sizes, while the output port of the sandblasting mechanism is fixed, the output port may be larger than the roll itself. This results in wasted material and compromises the equipment's performance. Therefore, a new mirror roll sandblasting system is urgently needed to address these issues. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a mirror roll sandblasting equipment that can select the guide shroud according to the specifications of the mirror roll, prevents dry spraying, avoids material waste, and has high performance and good sandblasting effect.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a mirror-finishing sandblasting device, including a housing, a hollow rotating shaft installed inside the housing, a secondary gear fixed at one end of the rotating shaft, a main gear connected to one side of the secondary gear, a drive motor installed on the main gear, multiple sets of connecting pipes distributed circumferentially on the outer wall of the rotating shaft, a solenoid valve installed on the connecting pipe, a guide shroud of different specifications fixed at one end of the connecting pipe, a storage box fixed at the top of the housing, a guide pipe leading out from the bottom of one side wall of the storage box, a pump body installed on the guide pipe, and a connecting ring provided between the guide pipe and the rotating shaft.

[0008] Furthermore, the rotating shaft is rotatably mounted inside the housing, the secondary gear meshes with the primary gear, and the output shaft of the drive motor is fixedly connected to the primary gear.

[0009] By adopting the above technical solution, the drive motor drives the main gear to rotate, and the main gear drives the rotating shaft to rotate through the secondary gear, thereby adjusting the guide shield that is put into use.

[0010] Furthermore, the connecting pipe is welded to the rotating shaft, the solenoid valve is threaded onto the connecting pipe, and the flow guide is welded to one end of the connecting pipe.

[0011] By adopting the above technical solution, the solenoid valve can open the connecting pipe on the guide shroud that is in use, and at the same time close the connecting pipe on the guide shroud that is not in use, thereby allowing sandblasting particles to be ejected through the guide shroud that is in use to perform sandblasting treatment on the mirror roll.

[0012] Furthermore, the storage tank is fixed to the top of the cover with bolts, the guide pipe is welded to one side wall of the storage tank, and the pump body is fixed to the guide pipe with bolts.

[0013] By adopting the above technical solution, the pump body can extract sandblasting particles from the storage tank through the guide pipe.

[0014] Furthermore, the connecting ring is welded to one end of the guide tube, the rotating shaft is rotatably connected to the connecting ring, and a sealing ring is provided at the connection between the rotating shaft and the connecting ring.

[0015] By adopting the above technical solution, the extracted sandblasting particles enter the rotating shaft through the connecting ring, while the connecting ring can ensure the rotation performance of the rotating shaft.

[0016] Furthermore, a support platform is fixed to the bottom of the cover, and a conveyor belt is rotatably installed inside the support platform.

[0017] By adopting the above technical solution, the conveyor belt can transport the mirror roll into the housing for sandblasting.

[0018] Furthermore, electric push rods are symmetrically arranged on both sides of the support platform, and guide plates are fixed on the movable parts of the electric push rods.

[0019] By adopting the above technical solution, the electric push rod can adjust the spacing of the guide plates according to the specifications of the mirror roll, thereby guiding the mirror panel during the conveying process.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the problem that existing mirror roll sandblasting equipment uses a pump to extract sandblasting particles, creating a high-speed airflow that is then sprayed onto the surface of the conveyed mirror roll, thus achieving sandblasting treatment, this invention solves the problem. Because mirror rolls come in various sizes, while the output port of the sandblasting mechanism is of a fixed size, the output port may be larger than the mirror roll, leading to dry spraying, material waste, and reduced equipment performance. This invention addresses this issue by incorporating a drive motor, a rotating shaft, a main gear, a secondary gear, and four sets of guide shrouds of different sizes. During operation, the drive motor rotates the main gear, which in turn drives the rotating shaft via the secondary gear, allowing for the selection of guide shrouds that match the mirror roll specifications. This effectively prevents dry spraying, avoids material waste, and enhances the equipment's performance and sandblasting effect. Attached Figure Description

Solenoid valves 16 are installed on the connecting pipes 15, and guide shrouds 14 of different specifications are fixed to one end of each connecting pipe 15. The solenoid valve 16 can open the connecting pipe 15 on the guide shroud 14 that is in use, and close the connecting pipe 15 on the guide shroud 14 that is not in use, so that the sandblasting particles can be sprayed out through the guide shroud 14 that is in use to sandblast the mirror roll. The top of the cover 5 is fixed with a storage box 6, and a guide pipe 7 is led out from the bottom of one side wall of the storage box 6. A pump body 8 is installed on the guide pipe 7.
