Technical Field

The utility model relates to the field of straw processing, in particular to an extrusion device capable of preventing blockage.

Background Art

Plastic straws are usually made of materials such as polypropylene or polyethylene through an extrusion molding method. Plastic particles are put into an extruder and melted under heat and pressure. The molten plastic is extruded through the extrusion port of the mold to form a continuous plastic tube. The plastic tube is cooled and solidified using a cooling device.

Chinese patent CN202222207948.7 discloses a plastic straw extrusion device, including a drive assembly and an extrusion barrel and a second screw rod rotatably connected to the extrusion barrel, the extrusion barrel is movably connected to a lower bin, the lower bin is rotatably provided with a connected first screw rod, and the first screw rod is provided with a dispersion rod in a linear array. The plastic straw extrusion device provided by the utility model utilizes a drive assembly. When the plastic raw material is put into the lower bin, the drive assembly is used to simultaneously drive the second screw rod and the first screw rod to rotate, so that the raw material slides along the lower bin to the discharge port, and at the same time, the heating plate heats the raw material through the fan to blow hot air onto the raw material, so that the raw material is quickly air-dried. Due to the accumulation of the raw material, it slides from the discharge pipe into the extrusion barrel, and then the raw material is extruded and heated, and the water stains on the raw material are quickly removed without hindering the production of the straw, so as to improve the work efficiency. However, when the plastic raw material fed in has impurities, it is easy to cause the discharge port to be blocked, which needs to be improved.
