Description

Technical Field

[0001] The utility model relates to the technical field of plate grinding and dust removal, in particular to a plate grinding and dust removal device. Background Art

[0002] Plate grinding is a means of plate processing, which is mainly used to remove uneven parts of the plate surface, such as burrs, protrusions or depressions, to make the surface smoother and more uniform. It can also be used to remove oil, dust and other impurities on the plate surface to provide better adhesion conditions for subsequent coating or gluing processes. Dust is inevitably generated during the plate grinding process, and a plate grinding dust removal device is needed at this time.

[0003] Some plate grinding and dust removal devices currently on the market: for example, the utility model patent with authorization announcement number CN210452212U discloses a new type of plate grinding and dust removal device, which is provided with a telescopic spring inside the side wall of the fixed cover. When the fixed cover is squeezed, the sliding cover will slide inside the side wall of the fixed cover through the first sliding groove to grind the plate. At the same time, under the action of the telescopic spring, the sliding cover has an outward tension, which is beneficial to prevent the powder of the plate from leaking out during the grinding process. The air guide groove is an annular spiral structure fixed to the inner side of the side wall of the sliding cover. The wind force generated by the rotation of the grinding wheel causes the dust to flow through the air guide groove and then be discharged through the dust exhaust hole, thereby avoiding the dust from being stored inside the sliding cover and affecting the use of the grinder body. However, since the device lacks a mechanism for collecting dust, the dust generated by grinding is directly discharged through the dust exhaust hole, resulting in pollution to the surrounding environment and affecting the health of the staff.

[0004] Therefore, we proposed a plate grinding and dust removal device to solve the above problems. Utility Model Content
