Perforating machine for plastic

Abstract

The invention relates to a perforating machine for plastic. The perforating machine comprises a perforating rod, a sliding groove and two clamping plates. The perforating rod is connected into the sliding groove in a sliding mode, a first connecting rod is hinged to the left end of the perforating rod, and a first crank is hinged to the first connecting rod. A first slide rail is arranged at the right side of the perforating rod, the two clamping plates are sequentially connected to the first slide rail in a sliding mode from left to right, a fixing block is arranged at the right end of the first slide rail, and springs are connected between the clamping plate located on the side away from the sliding groove and the fixing block. The two clamping plates abut against each other, and an opening for the perforating rod to pass through is formed in the clamping plate located on the side close to the sliding groove. A second slide rail is arranged above the two clamping plates and connected with a pressing block in a sliding mode, a second connecting rod is hinged to the pressing block, and a second crank is hinged to the second connecting rod. Compared with the prior art, the pressing block and the two clamping plates are matched to enable a wood board to be fixed more stably, and therefore the stability of the wood board is enhanced, and the probability that the pointed end of the perforating rod makes scratches on the surface of the wood board is lowered.

AI Technical Summary

Problems solved by technology

[0004] The punching machine in the prior art generally includes a punching rod arranged vertically. Two splints are arranged below the punching rod. The downward movement punches holes on the plastic sheet; during the punching process, since the two splints only clamp the plastic sheet in the left and right directions, when the punching rod acts on the plastic sheet, the plastic sheet tends to move back and forth , causing the tip of the punching rod to scratch the surface of the plastic sheet, and the scratches on the plastic sheet will be difficult to repair, which not only wastes materials, but also increases the processing cost
