Belt sander belt wheel device convenient to adjust tension degree of abrasive paper belt

Abstract

The invention relates to the technical field of belt sanders, and discloses a belt sander belt wheel device convenient to adjust the tension degree of an abrasive paper belt. The belt sander belt wheel device comprises two mounting base frames, wherein mounting supporting plates are fixedly arranged at the tops of the mounting base frames, a first mounting block is fixedly arranged at the top of the mounting supporting plate on the left side, and a second mounting block is fixedly arranged at the top of the mounting supporting plate on the right side; and a mounting groove is formed in the right side of the first mounting block, an adjusting sliding groove is formed inside the mounting groove, and a sliding plate located in the mounting groove and slidably connected with the adjusting sliding groove is fixedly arranged on the left side of the second mounting block. According to the belt sander belt wheel device convenient to adjust the tension degree of the abrasive paper belt, by arranging second connecting plates, when a conveying belt is loosened, a user can pull the mounting base frame on the right side rightwards, so that the device has the advantage of conveniently adjustingthe tension degree of the abrasive paper belt, and the belt sander belt wheel device is convenient for the user to use.

Description

technical field [0001] The invention relates to the technical field of abrasive belt machines, in particular to a belt pulley device for adjusting the tension of the sandpaper belt. Background technique [0002] A belt machine, a working instrument, includes an abrasive belt, an abrasive belt housing for accommodating the abrasive belt, a motor, a motor housing for accommodating the motor, a handle, a driving wheel, a driven wheel, and a transmission device connecting the motor and the driving wheel . [0003] Abrasive belt machines can be divided into desktop abrasive belt machines, vertical abrasive belt machines, hand-push belt abrasive machines, dust removal belt abrasive machines, etc., but the existing abrasive belt machines on the market are not convenient to adjust the tension of the sandpaper belt. It is too tight and inconvenient to move, causing the user to loosen the sandpaper belt after long-term use and the user needs to spend too much time when transferring t...
