And then carrying out cold air setting on the POE film. Prevent POE film from taking place stress deformation, effectively improve the product quality of POE film. And POE film passes through the transportation net curtain 22 tiling and carries, and reducible pulling and dragging to POE film further avoid the product to receive to drag and take place to warp, effectively improve the quality of product.

(3) The storage mechanism 3 drives the square frame 32 to lift through the screw rod 36 mechanism, so that the distance between the tension induction roller 33 and the matching roller 34 is adjusted, the winding length of the film is increased or reduced, the effects of storing and discharging are achieved, and the film conveying speed can better follow the winding speed of the film. And the tension sensing roller 33 senses the tension of the film, the signal is sent to the control system, the control system sends the signal to the storage motor 35 to form real-time closed-loop control, the storage motor 35 can adjust the position of the tension sensing roller 33 along with the change of the tension of the film, and therefore the tension of the film is automatically adjusted.

(4) According to the utility model, the POE raw material in the machine barrel main body 11 is heated or cooled by adopting the heat conduction oil, so that the temperature control is more accurate, the temperature control efficiency is higher, and the extrusion efficiency of the raw material is improved. In addition, the temperature control by adopting the heat conduction oil has lower power consumption, thereby greatly reducing the production cost.

(5) This is novel to be sent into guide hopper 621 through first recovery deflector roll 61 and the direction of second recovery deflector roll 625 after the cutting in, later the rim charge rethread retrieve main roll 622 and retrieve the secondary roller 623 by the guide hopper 621 in send into extrusion device 1 again inside, extrusion device 1 directly heats the rim charge and recycles, avoids the rim charge extravagant. The scrap recovery efficiency is improved, and the labor cost is reduced.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
