The third gear 113 further transmits power to the fourth gear 114 meshed therewith, so that the fourth gear 114 also starts to rotate, since the second gear 112 and the fourth gear 114 are coaxially connected with the first sub-wire wheel 115 respectively, the rotation of the second gear 112 and the fourth gear 114 will synchronously drive the respective first sub-wire wheel 115 to rotate.

When the edge trimming mechanism is started, the rotating driving member 111 drives the wire wheel to make the tangent line 117 run at high speed, starts to trim the edge of the workpiece 4 to be trimmed, and the nozzle 118 connected with the external gas source also starts to work, and the gas flows to the nozzle 118 through the gas delivery pipe. Since the internal size of the nozzle 118 narrows towards the outlet direction, the flow rate of the gas in the nozzle 118 gradually increases, when the gas reaches the output end of the nozzle 118, it is sprayed at high speed from the flat and narrow outlet, forming a concentrated gas flow, which directly blows to the side of the tangent line 117 close to the workpiece 4 to be trimmed, can timely blow the debris generated when the tangent line 117 cuts the workpiece away from the cutting area, and prevents the tangent line 117 from sticking to the glue.

[0040] The edge trimming mechanism is further provided with an oil storage assembly, which comprises an oil storage box 1110 and an oil storage piece 119 communicated with the oil storage box 1110, the tangent line 117 passes through or at least adheres to the oil storage piece 119, lubricating oil is injected into the oil storage box 1110 through an oil injection port, and the lubricating oil is delivered into the oil storage piece 119 embedded in the oil storage box 1110. Since the oil storage piece 119 is made of sponge, felt pad or fiber fabric and the like materials with good oil absorption performance, the lubricating oil is absorbed and stored by the oil storage piece 119, and the tangent line 117 passes through or adheres to the oil storage piece 119 during continuous operation. When the tangent line 117 contacts the oil storage piece 119, the lubricating oil in the oil storage piece 119 is attached to the tangent line 117. The lubricating oil forms a thin oil film on the tangent line 117, which avoids sticking and effectively reduces the friction of the tangent line 117 with the workpiece 4 to be trimmed and its own internal friction during high-speed operation. Reducing the friction with the workpiece can improve the efficiency and quality of edge trimming and make the cutting more smooth, and reducing the internal friction can reduce the wear of the tangent line 117 due to friction and prolong the service life of the tangent line 117.
