Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and specifically to a polishing equipment for producing anti-burning and sticking coatings. Background Technology

[0002] Anti-stick coating is a special type of coating that is mainly used to prevent materials from sticking together under conditions such as high temperature, high pressure, or high friction.

[0003] In the preparation of the coating, the substrate surface is first cleaned and roughened using a sandblasting machine. Then, a flame spraying device is used to feed the alloy powder into a supersonic flame to heat and accelerate the powder, causing it to impact the substrate at high speed, ultimately forming a mechanical bond between the powder and the substrate. Finally, a grinding device is used to polish the coating to make it smooth.

[0004] A grinding device for anti-burn-adhesion coating production is used to pre-treat the surface of a workpiece before coating application, or to repair coating defects. Its purpose is to remove rust, oxide layers, old coatings, and other impurities from the workpiece surface, achieving a suitable surface roughness to enhance the adhesion between the coating and the workpiece. Simultaneously, during coating repair, grinding helps the repaired area blend better with the surrounding coating.

[0005] The belt sander disclosed in Chinese Patent CN108188882A includes: a base, a fixed bracket, a first tensioning wheel, a second tensioning wheel, a third tensioning wheel, a sanding belt, a support platform, a protective guide plate, and a drive device. The fixed bracket is fixed to the base. The first and second tensioning wheels are arranged vertically, and the third tensioning wheel is located to one side of the second tensioning wheel. The first, second, and third tensioning wheels are mounted on the fixed bracket. The sanding belt is sleeved on the first, second, and third tensioning wheels. The support platform is located on the base and to the other side of the first and second tensioning wheels. The support platform has a notch, and the sanding belt sleeved on the first and second tensioning wheels is located within the notch. The protective guide plate is positioned to one side of the support platform. The drive device is connected to the third tensioning wheel to drive the third tensioning wheel to rotate.

[0006] However, compared with existing technologies and comparative solutions, it can be seen that this belt sander still has the following problems in actual use: When grinding a flat surface, a support plate supports the abrasive belt between two pulleys to ensure the smoothness of the grinding. However, during the grinding process, the high-speed rotating abrasive belt is pushed by the workpiece being ground, and friction occurs directly between it and the support plate. On the one hand, this causes wear on the support plate and the abrasive belt, affecting the service life of the abrasive belt. On the other hand, since the support plate is rigid, the abrasive belt may jump when the abrasive belt joint passes through the support plate due to the difference in thickness, affecting the final grinding effect. Summary of the Invention

[0007] This invention provides a grinding device for producing anti-burning and sticking coatings to solve the above-mentioned technical problems.

[0008] The present invention provides a grinding device for producing an anti-burning and sticking coating, which adopts the following technical solution: including a frame, a driving component on the frame, a tensioning mechanism on the frame, an auxiliary support mechanism on one side of the frame, a placement mechanism on the auxiliary support mechanism, and a grinding belt on the frame.

The support assembly includes multiple connecting plates, each equipped with a rotating component and a friction component. The multiple connecting plates are connected end-to-end via the rotating component.

[0009] Furthermore, a first electric push rod and a second electric push rod are hinged on the frame, a first rotating block and a first fixing bolt are provided on the frame, an active roller is provided at the output end of the drive component, a first transmission wheel is provided at one end of the active roller, a connecting frame is rotatably connected to the frame, and the output end of the first electric push rod is hinged to the connecting frame.

[0010] Furthermore, the tensioning mechanism includes a first connecting frame, on which an elastic element and a tensioning roller are disposed.

[0011] Furthermore, the placement mechanism includes a third connecting frame, which is rotatably connected to the second connecting frame via a second rotating block. The third connecting frame has a second through groove and a sliding groove. A second fixing bolt is set in the second through groove. A placement plate is set on the third connecting frame, and a sliding plate is slidably connected in the sliding groove.

[0012] Furthermore, the second connecting frame is rotatably connected to the frame via the first rotating block, the first fixing bolt is set in the first through slot, the output end of the second electric push rod is hinged to the first connecting block, and the first transmission wheel is connected to the second transmission wheel via a transmission belt.

[0013] Furthermore, the abrasive belt is positioned on the outside of the drive roller, tension roller, and support assembly.

[0014] Furthermore, there are multiple support wheels, and the first gear is fixedly connected to one of the support wheels.

[0015] Furthermore, the friction element is a rubber strip, and the support wheel has a meshing groove adapted to the rotating element.

[0016] Furthermore, the first connecting bracket is slidably connected to the connecting frame.

[0017] Furthermore, an elastic element is provided between the first connecting frame and the frame, and a telescopic rod is also provided between the first connecting frame and the frame.

[0018] The beneficial effects of this invention are: when grinding a flat workpiece, the support component and the grinding belt are relatively stationary, which avoids wear on the grinding belt and ensures the service life of the grinding belt. Moreover, while the support component moves synchronously with the grinding belt, it always supports the grinding belt, ensuring the smooth operation of the grinding belt and preventing the grinding belt from jumping, thereby ensuring the grinding effect.
