Self-pre-tightening type plate grinding and polishing device and using method thereof

Abstract

The invention discloses a self-pre-tightening type plate grinding and polishing device and a using method thereof. The self-pre-tightening type plate grinding and polishing device comprises an unpowered negative pressure capillary type grinding agent supply mechanism, a broken contact type polishing belt self-pre-tightening mechanism, a disc type hanging type grinding mechanism, a polishing belt driving and guiding mechanism and a low-resistance guiding and limiting mechanism. The invention belongs to the technical field of plate grinding, and particularly relates to a self-pre-tightening plate grinding and polishing device and a using method thereof. Through the mode that transmission of the lead screw is matched with pre-tightening of the spring, the polishing belt body can be automatically tightened in the polishing process, self-adaptive adjustment can be conducted according to the width of a to-be-polished plate body, and the polishing efficiency is greatly improved under the condition that no adjusting mechanism or manual binding mechanism exists. The technical effects of self-adaptive adjustment and binding are achieved only through simple mechanical linkage; the grinding agent is continuously and slowly extracted from bottom to top through the capillary phenomenon and the negative pressure extraction phenomenon, and therefore the technical effect of continuously conveying the grinding agent to the grinding position is achieved.

Description

technical field [0001] The invention belongs to the technical field of plate grinding, in particular to a self-preloading type plate grinding and polishing device and a method for using the same. Background technique [0002] Plates of various materials need to be ground and polished before assembly. Most wood plates need to be polished with oil and wax to improve the texture and flatness of the surface. Except for wood, most other materials All the plates also need to add grinding aids of different materials. The existing plate polishing process is mainly completed manually or semi-automatically. The main problems are as follows: [0003] A: The efficiency is slow. General grinding tools can only grind one surface at a time, and the grinding width is limited. During the polishing and grinding process, the plate needs to be turned over; [0004] B: The steps are cumbersome: the grinding of large and small faces and edges and corners requires replacement of different grindin...

Problems solved by technology

[0008] In order to solve the problem that the auxiliary abrasive needs to be manually added, the present invention creatively proposes a non-powered negative pressure capillary abrasive supply mechanism and a self-oil supply disc polishing assembly, which transports the abrasive to the grinding disc through centrifugal force, and regardless of the grinding disc High or low speed, the delivery efficiency of the abrasive can be basically kept stable; the abrasive is continuously and slowly extracted from bottom to top through the capillary phenomenon and negative pressure extraction phenomenon, so as to realize the technical effect of continuously delivering the abrasive to the grinding position
