Description

Technical Field

[0001] This utility model relates to the field of polyester filament processing technology, and more specifically, to a uniform extrusion device for processing elastic polyester filament melt. Background Technology

[0002] Polyester filament is the commercial name for polyester fiber in China. Its characteristics include resistance to chemicals and frequent washing, reducing fading and discoloration in clothing. Therefore, it is used in the manufacture of hotel uniforms, stonewashed denim, sportswear, and children's clothing. Relatively speaking, polyester filament is more durable than rayon. When embroidering, the machine operates at high speeds, and the high-tenacity polyester thread can withstand significant tensile force; moreover, it has extremely high fire resistance; even if the clothing is near a flame, it is not easily ignited.

[0003] Polyester filament production requires extrusion through an extruder. Existing polyester filament extruders lack the ability to agitate the polyester raw material before extrusion, resulting in insufficient mixing of the polyester raw material and additives. This leads to uneven extruded polyester filaments, affecting their performance. In addition, existing polyester filament extruders lack preheating treatment of the polyester raw material, which affects extrusion efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0027] Example 2;

[0028] like Figure 1-5As shown, the device includes an extrusion box 1, a mixing tank 2 at its top, a feeding pipe 3 on the outer wall of the mixing tank 2, a conveying groove 4 in the extrusion box 1, a conveying auger 5 in the conveying groove 4, the conveying groove 4 being connected to the mixing tank 2, a solenoid valve 6 at the bottom of the mixing tank 2, an installation groove 7 in the extrusion box 1 located at the top of the conveying groove 4, an electric heating wire 8 in the installation groove 7, an extrusion die 9 matching the conveying groove 4 on one side of the extrusion box 1, the shaft end of the conveying auger 5 extending outside the extrusion box 1 and connected to the drive end of a drive motor 10, and a stirring and preheating assembly in the mixing tank 2. Several evenly distributed support blocks 11 are provided at the bottom of the extrusion box 1, and anti-slip blocks are provided at the bottom of the support blocks 11. A cleaning door 24 is provided on the outer wall of the mixing tank 2. The stirring and preheating assembly includes a plurality of hollow stirring shafts 12 arranged in a circumferential array within the stirring tank 2. Each hollow stirring shaft 12 has a plurality of hollow stirring blades 13 connected to its outer wall. Each hollow stirring blade 13 has a plurality of evenly distributed air vents on its outer wall. A fixing frame 14 is provided at the top of the stirring tank 2. The tops of the plurality of hollow stirring shafts 12 arranged in a circumferential array extend outside the stirring tank 2 and are connected to the fixing frame 14 via a linkage assembly. The fixing frame 14 contains... An annular tube 15 is provided, which is connected to the fixed frame 14 via a connecting bracket 16. The annular tube 15 is connected to the hollow stirring shaft 12 via a rotary joint 17. An installation groove 18 is provided in the extrusion box 1 at the top of the first installation groove 7. A heat exchange tube 19 is provided in the second installation groove 18. One side of the heat exchange tube 19 extends outside the extrusion box 1 and connects to the annular tube 15, while the other side of the heat exchange tube 19 extends outside the extrusion box 1 away from the annular tube 15. An exhaust fan 20 is provided at the top of the extrusion box 1 and on the heat exchange tube 19. A dustproof net is provided at the end of the heat exchange tube 19 away from the annular tube 15.

By setting up a stirring and preheating component, the polyester filament material can be preheated so that it can melt quickly upon entering the conveying trough, thereby improving extrusion efficiency. The stirring and preheating component utilizes the waste heat of the extrusion device by using a hollow stirring shaft, hollow stirring blades, air outlet, annular tube, heat exchange tube, and induced draft fan to heat the external air and preheat the polyester filament material, making it more energy-efficient and environmentally friendly.

[0030] In summary, by utilizing the above-mentioned technical solution of this utility model, the polyester filament raw material can be preheated by setting up a stirring and preheating component, so that it can melt quickly when it enters the conveying tank, thereby improving the extrusion efficiency. The stirring and preheating component utilizes the waste heat of the extrusion device by cooperating with a hollow stirring shaft, hollow stirring blades, air outlet, annular tube, heat exchange tube and induced draft fan to heat the external air and preheat the polyester filament raw material, which is more energy-saving and environmentally friendly.
