This device usually includes components such as a heating system, a melting device, an extruder and a molding device. First, the discarded polyester fibers or plastics are collected and fed into the device, and then they are converted into molten raw materials through a heating and melting process. Next, the molten raw materials are extruded through an extruder to form continuous fibers or granular materials, and finally they are shaped into the desired recycled polyester fiber products through a molding device.

The beneficial effects of the utility model are: by adding a rack and teeth, the rack is meshed with the teeth when it moves, and the mixing barrel is driven by the teeth to rotate and adjust when the rack moves. When the mixing barrel rotates, the electric heating rod at the bottom of the fixed rod is used to heat and mix the internal regenerated polyester fiber raw materials, and the central part of the regenerated polyester fiber raw materials is fully melted. By adding an extrusion bin, the raw materials input into the extrusion bin by the conduit are squeezed into the melt spinning body for spinning operation. By adding a blocking plate, the blocking plate controls the connection of materials in the feed pipe and blocks the feeding.

[0004] In a specific implementation manner of the above patent, raw materials or additives are added into the feed pipe, and the added amount is observed through an observation window on one side of the feed pipe. After the addition, motor No. 2 is started through the control panel, and the output end of motor No. 2 drives the adjusting screw to rotate, and when the adjusting screw rotates, it drives the sliding plate and the blocking plate to move and adjust the position, and the blocking plate cancels the closure of the feed pipe, and the raw materials or additives can be added into the mixing barrel, and the electric heating plate and the electric heating rod are turned on to heat the raw materials in the mixing barrel, and motor No. 1 is started through the control panel, and the output end of motor No. 1 drives the reciprocating screw to rotate, and when the reciprocating screw rotates, it drives the sliding block and the rack to move the position, and the rack rotates the mixing barrel through the meshing teeth, and when the mixing barrel rotates, the position of the fixed rod and the electric heating rod is fixed, the raw materials in the mixing barrel are stirred, and the raw materials in the middle position are heated by the electric heating rod. Uniform stirring treatment, open the electric control valve on the discharge pipe, enter the extrusion chamber at the bottom of the conduit, and input the raw materials into the melt spinning machine through the extrusion chamber for processing. In this patent, by adding an extrusion chamber, the raw materials input into the extrusion chamber from the conduit are squeezed into the melt spinning machine for spinning operation. By adding a blocking plate, the blocking plate controls the connection of materials in the feed pipe and blocks the feeding. However, in this patent, the positions of the fixed rod and the electric heating rod are fixed when the mixing barrel rotates. The raw materials in the mixing barrel are stirred.
