[0002] A chimney is a structure that provides ventilation for the hot flue gases or fumes from a boiler, furnace, stove or fireplace. Chimneys are usually vertical, or as close to vertical as possible to ensure a smooth flow of gases. The space inside the chimney is called a flue. The main function of a chimney is to draw out fire and smoke, exhaust the smoke and improve combustion conditions. According to the material, chimneys are generally divided into brick masonry, iron, asbestos, and ceramic. These types are generally used in small places such as homes and offices.

The supporting beam 900 is slidably provided on the side main body frame 300 and the sliding direction of the supporting beam 900 is consistent with the width direction of the polishing table body 100. The displacement adjustment cylinder 800 is connected to the supporting beam 900 and the displacement adjustment cylinder 800 is used to adjust the distance between the supporting beam 900 and the polishing table body 100. The polishing assembly 400 is provided on the top of the supporting beam 900 and the polishing assembly 400 can move on the top of the supporting beam 900 along the length direction of the polishing table body 100.

When the polishing arm 430 rotates toward one side of the polishing table 100, the polishing arm 430 contacts the top of the upper supporting rod 720 and presses the upper supporting rod 720 downward, thereby the brake rack 710 moves downward and engages synchronously with the multiple brake gear parts 150, thereby limiting the rotation of the multiple brake gear parts 150; when the polishing arm 430 rotates, by releasing the deformation rebound force of the spring 750, the sliding sleeve part 741 pushes the brake rack 710 and the upper supporting rod 720 upward through the lower supporting rod 740, thereby the brake rack 710 is disengaged from the brake gear part 150, and then the material conveying roller 120 can rotate and convey the chimney body 200 under the drive of the conveying motor 130; since the upper surface of the upper supporting rod 720 has a ball portion 730 and the ball portion 730 is in rolling contact with the polishing arm 430, the friction force when the polishing arm 430 moves relative to the upper supporting rod 720 can be effectively reduced.

[0035] The above embodiment provides a surface polishing device for chimney processing, wherein the two ends of the chimney body 200 can be pressed on the two pressure-bearing adjustment parts 600, and the two pressure-bearing adjustment parts 600 move downward. The downwardly moving pressure-bearing adjustment parts 600 drive the side clamping roller assembly to extend to the end portion on the upper side of the polishing table 100 and approach the chimney body 200. When the top of the pressure-bearing adjustment part 600 is flush with the arc top of the supporting material conveying roller 120, the two ends of the side clamping roller assembly contact the side wall of the chimney body 200, thereby limiting the chimney body 200 from moving along the polishing table 10 0 rolls in the width direction of the polishing assembly 400; the polishing assembly 400 starts working and contacts the arc top of the chimney body 200, and the polishing assembly 400 also reciprocates along the length direction of the chimney body 200 on the top of the supporting crossbeam 900, so that the moving polishing assembly 400 polishes the arc top part of the chimney body 200; after the polishing of the arc top part of the chimney body 200 is completed, the displacement adjustment cylinder 800 drives the supporting crossbeam 900 to move along the width direction of the polishing table 100, and the supporting crossbeam 900 drives the polishing assembly 400 to move along the width direction of the polishing table 100. 00 and the side clamping roller assembly move laterally, and the side clamping roller assembly pushes the chimney body 200 to roll along the width direction of the polishing table body 100, so that the original side part of the chimney body 200 rolls to the arc top, and the polishing assembly 400 polishes the arc bottom of the chimney body 200 again. Such reciprocating operation can fully polish the outer surface of the chimney body 200; after the surface polishing of the chimney body 200 is completed, the conveying motor 130 drives the supporting conveying roller 120 to rotate, and the rotating supporting conveying roller 120 drives the front of the chimney body 200 on it The chimney body 200 is moved out from one end of the polishing table 100, so that the material can be unloaded automatically. During the entire polishing process, the chimney body 200 is supported by the polishing table 100 and only needs to be pushed to roll on the polishing table 100 so that its surface can be placed on the top of the arc in turn, and the polishing assembly 400 can be moved to perform comprehensive polishing. The efficiency is high and there is no need to lift the chimney body 200, which is convenient for operation. The side clamping roller assembly can clamp the chimney body 200 from both sides to prevent the chimney body 200 from rolling horizontally during polishing, thereby improving the polishing effect.
