Plastic Profile Extrusion Line

The workflow of PVC ceiling panel making machine: Raw Material Mixing—–Extruder ——Extrusion Die——Sizing Table——Tractor——Cutting Machine—–Stacking Frame ;The model of Beisu Machinery’s plastic profile extruder: SJZ51/105, 55/120, 65/132, 80/156 conical twin screw extruder.

A1: Raw material mixing: PVC, fillers, stabilizers, plasticizers, antioxidants and other auxiliary materials are added to the high-speed mixer according to the proportion and process, and the materials are heated to the set process temperature through self-friction between the materials and the machine , And then reduce the material to 40-50oC by the cold mixer; in this way, it can be added to the hopper of the extruder;
A2: Extrusion die head part: PVC is compacted, melted, mixed and homogenized, and the subsequent materials are pushed to the die head by the screw. The extrusion die head is a key part of profile forming;
A3: The vacuum shaping cooler is used for shaping and cooling the profile. The vacuum shaping cooler is equipped with a vacuum system and a water circulation system for shaping and cooling. The stainless steel box body is immersed in circulating water for cooling. The vacuum shaping cooler is equipped with forward and backward moving devices and Manual device for left and right, height adjustment;
A4: The traction machine is used to continuously and automatically draw the cooled and hardened profile from the nose, frequency conversion and speed regulation;
A5: Cutting machine part: After the travel switch is controlled according to the required length, it will automatically cut, and delay the turning frame, and implement the flow production. The cutting machine uses the fixed-length switch signal as the instruction to complete the whole cutting process, and the profile is in the cutting process The operation is kept synchronized, and the cutting process is completed by electric and pneumatic drives. The cutting machine is equipped with a dust suction device to suck out the cutting debris in time and recover it;
A6: The turning action of the turning frame is realized by the air cylinder through the air circuit control. The turning frame is equipped with a limit device. When the cutting saw cuts the profile, the profile continues to be conveyed. After a delay, the cylinder enters the work to realize the turning action. , To achieve the purpose of unloading. After unloading, it will automatically reset after a few seconds delay, and wait for the next cycle;
