The reciprocating screw rod rotates to make the wire block move back and forth, thereby driving the trimmer to move back and forth, so that multiple rubber rings can be trimmed.

[0010] Preferably, the outer wall of the reciprocating screw and the outer wall of the rotating shaft are both equipped with transmission wheels, and the two transmission wheels are driven by transmission belts. Through the transmission of the transmission wheels and the transmission belts, the rotating shaft rotates and the reciprocating screw is driven to rotate at the same time, saving the use of a motor and reducing the subsequent maintenance cost of the motor.

[0012] Preferably, a bottom groove is opened at one end of the top of the L-shaped chassis, and a scraper is slidably installed in the bottom groove. An electric push rod is installed at one end of the L-shaped chassis, and the output end of the electric push rod is connected to one end of the scraper. The debris generated by trimming falls into the bottom groove, and the electric push rod drives the scraper to move, which can push the debris out and automatically clean the debris on the L-shaped chassis.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets a placing roller and a clamping mechanism, and the staff sets multiple rubber rings on the placing roller at one time, and then rotates and installs the movable ring on the placing roller. The multiple rubber rings are further limited by the fixed ring and the movable ring. The trimming machine can trim multiple rubber rings at the same time, and the trimming process takes longer, which reduces the frequency of replacing rubber rings and reduces fatigue of the staff;

[0015] 2. The utility model sets a driving mechanism, and the reciprocating screw rod drives the wire block to move back and forth left and right, drives the trimming machine to move left and right to trim the rubber ring, and also drives the connecting plate to move, starts the air pump, and makes the air nozzle on the air box spray gas, which can blow air to the surface of the trimmed rubber ring, clean up the attached debris, and facilitate the next step of processing of the rubber ring.
