An automatic chopping board edging machine

Abstract

The present invention belongs to the technical field of chopping block machining and discloses a polishing tripod for chopping block edging and an automatic chopping block edging machine. The polishing tripod is used for the automatic chopping block edging machine and comprises a frame which is in an isosceles triangle shape and three abrasive belt backup rollers distributed on the frame in an isosceles triangle shape. Abrasive belts are arranged on the three abrasive belt backup rollers in a sleeving way. Among the three abrasive belt backup rollers, the two backup rollers at the front end and with equal size are driven backup rollers, the line connecting the centers of both backup rollers is parallel to the moving direction of the chopping block to be edged; and an edging drive motor is disposed under the backup roller at the back end. An installing shaft of the backup roller at the back end is connected with the output end of the edging drive motor. An abrasive belt push device is disposed inside the triangular area enclosed by the abrasive belts. The push surface of the abrasive belt push device moves forward to push the abrasive belt to the chopping block on a chopping block support mesa. With the design of the polishing tripod, the structure of the automatic edging machine for the chopping block is simplified, and the stability of the machine is improved.

Description

technical field [0001] The invention belongs to the technical field of chopping board processing, and relates to equipment for processing the edges of chopping boards, in particular to an automatic chopping board edging machine. Background technique [0002] The edge treatment of the cutting board is an important procedure in the cutting board processing process, including the chamfering of the corners and the grinding of the side (usually called edging treatment). The existing cutting board is finished by a high-speed rotating grinding wheel or abrasive belt. Workers are required to hold the chopping block so that the sides of the chopping block are close to the emery wheel or abrasive belt to complete the edging action. It has the following disadvantages: 1. Manual intervention brings certain labor costs, especially in recent years when labor is increasingly scarce, workers’ wages are increasing, and labor costs are increasing day by day; Low efficiency; 3. Manual alignme...

It has the following disadvantages: 1. Manual intervention brings certain labor costs, especially in recent years when labor is increasingly scarce, workers’ wages are increasing, and labor costs are increasing day by day; Low efficiency; 3. Manual alignment of the side of the chopping board and the friction surface of the sandpaper has low accuracy, the side grinding force is uneven, and the smoothing effect is not uniform; 4. The pressure accuracy of the manual control of the chopping board on the sandpaper is low, and the friction of different cutting boards processed by the same worker The effect is not uniform
