Plastic extrusion drawing equipment

The invention belongs to the field of plastic processing machinery, and discloses plastic extrusion wire drawing equipment which solves the problem of unstable strength caused by water cooling of a plastic flat film in the prior art. The main technical scheme for solving the problem is that a cooling device comprises a first calendaring cooling roller and a second calendaring cooling roller; cooling water is communicated in the first calendaring cooling roller and the second calendaring cooling roller; a calendaring cooling gap for the plastic flat film to pass through is formed between the circumferential roll surface of the first calendaring cooling roll and the circumferential roll surface of the second calendaring cooling roll; the width of the calendaring cooling gap is smaller than the thickness of the plastic flat film extruded by an extrusion die; and the circumferential roll surface of the first calendaring cooling roll and the circumferential roll surface of the second calendaring cooling roll cool
