Spiral stirring plastic wire drawing machine

Abstract

The invention discloses a plastic drawing machine with a spiral stirring function and relates to extrusion molding equipment. The plastic drawing machine according to the technical scheme is characterized by comprising a drying device, an extruding device, a drawing device and a winding device which are sequentially connected; the drying device comprises a material box and a heater, as well as a motor and a rotating shaft driven to rotate by the motor; a spiral disc is fixed on the outer wall of the rotating shaft; the end, facing the rotating shaft, of the spiral disc is fixed to the outer wall of the rotating shaft; the end of the spiral disc far away from the rotating shaft extends outwardly and abuts against the inner wall of the material box; the edge of the spiral disc far away fromthe rotating shaft is provided with cutting teeth; notches for a plastic material to pass through are formed between the inner wall of the material box and the cutting teeth; and the cutting teeth cancut the plastic material at the notches. The plastic drawing machine allows plastic materials to be thoroughly dried, thereby ensuring the forming quality of plastic extruded by the extruding device;a plastic material is crushed in the drying device in advance, so that the plastic material is easier to melt in the extruding device; hot air can circulate in the material box more efficiently, so that the drying effect of the plastic material is good.

Description

technical field [0001] The invention relates to extrusion equipment, in particular to a plastic wire drawing machine. Background technique [0002] Plastic wire drawing machine is a device that uses plastic as raw material, heats, extrudes, cuts, and stretches to form a flat wire that is wound up and then woven by a circular loom. The products produced by the plastic wire drawing machine can be further made into plastic bags. The raw materials of the plastic wire drawing machine are mostly granular plastic raw materials and color masterbatches. [0003] The Chinese invention patent with the existing authorized notification number CN102534834B discloses a plastic flat wire drawing unit, including a drying conveying device, an extruder, a filter, a metering pump, a die head, a traction device, a wire dividing device, a stretching device, The collection device is distributed according to the process flow. The raw material in the extruder is subjected to various physical condi...
