Abstract

The invention discloses an edge material shearing device for plastic sheets. The edge material shearing device comprises an engine base, an upper cutter device and a lower cutter device. The inventionis characterized in that the a cylinder is arranged on the engine base, a push rod of the cylinder is connected with a hinge mechanism, the engine base is provided with a concave cavity, the hinge mechanism is fixed in the concave cavity, a connection rod of the hinge mechanism is fixedly connected with the upper cutter device, the blade of the upper cutter device is in the shape of a dovetail, the lower cutter device is arranged below the upper cutter device, and the blade of the lower cutter device is rectangular. The invention can be used for directly shearing edge materials and has high operation efficiency. Besides, the shear plane is smooth and clean; and the shearing device is especially safer and more reliable for shearing splintery materials.

Description

technical field [0001] The invention relates to the field of plastic sheet material processing, in particular to a plastic sheet material cutting device. Background technique [0002] In the production of plastic sheets, the plastic is continuously extruded from a viscous molten state by an extruder through a mold, cooled by a three-roll calender and a cooling roll to form a sheet, and then cut by a slitting knife (not cut, If it is cut open, the edge material will be pulled together with the finished board, which will cause the board to wander and the diagonal line will be bad), then the cross-cutting knife will cut it and transport it to the operation table, and the left and right sides of the board will be slit by the operator manually. Tear off separately, and finally get the plate of the specification required by the customer. [0003] The labor intensity of such a production method is high, and the cut surface is not smooth. When the plastic sheet is relatively brittl...
