An abrasive belt device with adjustable angle position

Abstract

The invention provides an abrasive belt device with an adjustable angle position. The abrasive belt device comprises a bottom plate installed on a base, the bottom plate is provided with an articulated wheel connected with a ratchet wheel and a movable sliding block for fixing a motor device, a revolving shaft of the motor device is connected with a grinding wheel, a rotating wheel is installed on the ratchet wheel, the rotating wheel is connected with a movable sliding block through a hinged push arm, the push arm is hinged to an eccentric position of the rotating wheel, the ratchet wheel extends to form a supporting arm, a supporting point at the tail end of the supporting arm is hinged to a push rod cylinder, the supporting arm is pushed through the push rod cylinder, the ratchet wheel drives the rotating wheel to rotate so as to enable the push arm to perform eccentric rotation, the movable sliding block is driven to slide along a guide rod, the motor device is driven to perform vertical sliding directly, and conversion effect of a grinding position of an abrasive belt is achieved.

Description

technical field [0001] The invention relates to the field of machinery and equipment for sanding boards, and further relates to an abrasive belt device with adjustable angular position that can adjust the grinding position of the abrasive belt. Background technique [0002] The processing of the plate is inseparable from the grinding of the abrasive belt. The abrasive belt can change the plate from a rough surface to a smooth surface, and change the right angle of the plate corner into a rounded corner process. The current sanding plate machine mainly The belt is installed on the sponge wheel, and through the softness of the sponge wheel, the abrasive belt set on the sponge wheel can follow the sponge wheel to make good contact with the corner or surface of the plate, and finally achieve uniform grinding of the plate Effect. [0003] However, the grinding of the abrasive belt is unavoidable because of the wear and tear problem. The current sanding machines on the market onl...

[0003] However, the grinding of the abrasive belt is unavoidable because of the wear and tear problem. The current sanding machines on the market only consider fixing the abrasive belt and sanding the board, but ignore that every inch of the abrasive belt can make the best use of it. Use, if the position of the abrasive belt is not changed, the contact surface between the abrasive belt and the plate will often be thin or even broken, while the other places will not be worn, just like the new one. There are two consequences, either the abrasive belt Remove it and replace it with a new one, or use manual operation to remove the sponge wheel, pull down the abrasive belt to the position that needs to be polished, and then install the sponge wheel. This procedure is cumbersome and it is easy to wear the machine parts. Choose the former , it will cause unnecessary waste of abrasive belts, which does not meet the needs of energy conservation and environmental protection advocated by the national policy
