Perforating machine for plastic

Abstract

The invention relates to a perforating device, and discloses a perforating machine for plastic. The machine comprises a perforating rod, a slide groove and two clamping plates, wherein the perforating rod is connected into the slide groove by sliding; a hydraulic cylinder is connected to the left end of the perforating rod, and a first slide rail is arranged at the right side of the perforating rod; the two clamping plates are connected to the first slide rail by sliding from left to right in a sequence; a fixing block is arranged at the right end of the first slide rail; a spring is connected between the fixing block and the clamping plate at one side far away from the slide groove; the two clamping plates are propped to each other; an opening through which the perforating rod can pass is formed in the clamping plate at one side close to the slide groove; a second slide rail is arranged above the two clamping plates; a propping block which is hinged with a connecting rod is in slide connection to the second slide rail; a crank which is hinged with a base is hinged with the connecting rod. Compared with the prior art, the perforating machine for the plastic has the advantages that the propping block is matched with the two clamping plates to stably fix a plastic plate, so that the stability of the plastic plate can be improved, and the probability that the surface of the plastic plate is scratched by a sharp end of the perforating rod can be reduced.

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
