Description

Technical Field

[0001] This utility model relates to the field of steel-plastic composite pipe grinding technology, specifically to a grinding dust removal device. Background Technology

[0002] During the processing of steel-plastic composite pipes, welding is sometimes required. Due to process limitations, weld points or weld seams are usually present during welding. Therefore, after the above process, the steel-plastic composite pipe needs to be ground to ensure the flatness or smoothness of the processed part.

[0003] In existing technologies, steel-plastic composite pipes are polished by a polishing mechanism to remove impurities and uneven parts from the metal surface. During this process, fine metal particles are generated, and the polishing mechanism, such as the grinding wheel and abrasive belt, gradually wears down, producing metal dust and abrasive particles. If dust removal is not carried out during polishing, the dust generated (composed of metal particles, abrasive particles and other impurities) will diffuse into the workshop. The generation of dust not only affects the working environment but may also harm the health of the operators. Utility Model Content

[0027] Please see Figures 1-4 , Figures 1-4This invention discloses a grinding and dust removal device for grinding the weld seams of steel-plastic composite pipes. It includes a housing 1, a grinding component 2, a support component 3, and a dust removal mechanism 4. The grinding component 2 is located inside the housing 1 and includes a grinding disc 21, which is rotatable around its own axis. The support component 3 is located inside the housing 1 and supports the steel-plastic composite pipe A passing through the housing 1. It also drives the steel-plastic composite pipe to move relative to the grinding disc 21 so that the weld seam of the steel-plastic composite pipe can contact the grinding disc 21. The dust removal mechanism 4 is connected to the housing 1 and is used to evacuate the housing 1 to create a negative pressure inside the housing 1 and to filter impurities in the gas.

[0028] In this specific embodiment, a rectangular box 1 is formed by welding multiple steel plates, and two corresponding through holes are opened on opposite sides of the box 1, through which the steel-plastic composite pipe can be inserted into the box 1.

[0029] It should be noted that the grinding component 2 is not limited to a specific structure, as long as it can grind the weld seam of the rotating steel-plastic composite pipe, no other limitations are made here.

[0031] Furthermore, when the steel-plastic composite pipe is installed inside the box, it can be supported by the support member 3. At the same time, the support member 3 drives the steel-plastic composite pipe to rise, so that the weld of the steel-plastic composite pipe comes into contact with the grinding disc. The operator manually rotates the steel-plastic composite pipe, and the weld can be ground by rotating the steel-plastic composite pipe around its own axis.

[0032] In one embodiment, the support member 3 includes at least two first telescopic portions 31 and a seat 32.
