Product introduction

This production line is a new type of high-speed and energy-saving production line developed by Qingdao Zhaoxing Plastic Machinery based on the introduction of foreign technology and the actual situation in China combined with the experience accumulated by our company for more than ten years. It is easy to operate and practical. This production line is characterized by beautiful appearance, high degree of automation and stable and reliable production.


(1) Mixing of raw materials: PVC stabilizers, plasticizers, antioxidants and other auxiliary materials are added into the high-speed mixer according to the proportion and process successively, and the materials are heated up to the set process temperature by the friction between the materials and the machinery, and then the materials are lowered to 40-50 degrees by the cold mixing machine; so that they can be added into the hopper of the extruder.

(2) Extruder part: This machine is equipped with a quantitative feeding device, so that the extrusion volume and the feeding volume can be matched to ensure stable extrusion of products. Due to the characteristics of conical screw, the charging section has a larger diameter, the heat transfer area and shear speed of the material is larger, which is conducive to the plasticization of the material, and the diameter of the screw in the metering section is small, which reduces the heat transfer area and the shear speed of the melt, so that the melt can be extruded at a lower temperature. When the screw rotates in the barrel, the PVC mixture is plasticized and pushed to the head, so as to achieve compaction, melting, mixing and homogenization; and to achieve the purpose of exhausting and dewatering. Feeding device and screw drive device adopts frequency conversion speed control, which can realize synchronous speed control.

(3) Extruding die head part: After compaction, melting, mixing and homogenization of PVC, there are subsequent materials pushed to the die head through the screw, the extrusion die head is a pipe forming the key components.

(4) shaping water tank for pipe shaping, cooling, vacuum shaping water tank is equipped with vacuum system for shaping and cooling and water circulation system, stainless steel box, circulating water spray cooling, vacuum shaping water tank is equipped with forward and backward moving device and left and right, high and low adjustment of manual device.

(5) Traction machine is used to continuously and automatically lead the cooled and hardened pipe out from the machine head, with frequency conversion speed control.

(6) Cutting machine: controlled by the travel switch according to the required length, automatic cutting, and delayed turn over the shelf, the implementation of streamlined production, the cutting machine to set the length of the work switch signal as a command to complete the whole process of cutting, in the process of cutting and pipe running to maintain synchronization, the cutting process is completed by the electric and pneumatic drive.

(7) Turn over the material frame turn over the material action by the cylinder through the pneumatic control to achieve, turn over the material frame is equipped with a limit device, when the cutting saw cut off the pipe, the pipe continues to transport, after a delay, the cylinder into the work, to achieve the turn over the material action, to achieve the purpose of unloading. After unloading after a delay of several seconds automatically reset, waiting for the next cycle.
