Description

Technical Field

[0001] This utility model relates to the field of texturing machine technology, specifically a polyester filament texturing machine. Background Technology

[0002] Texturing machines are important textile machinery, mainly used to process untwisted yarn into elastic yarn. Texturing machines go through three major steps: stretching, twisting, and setting. First, the polyester yarn is stretched to make the fiber molecules more compact to increase strength. Then, the fibers are twisted by mechanical rotation to make them curl and gain elasticity. Finally, the curled structure is fixed by high temperature to make the elasticity more stable.

[0003] In current texturing machines, the heating space is too large during the heating process of polyester yarn, and the hot air cannot fully wrap around a single polyester yarn in a relatively small space. The heating of the polyester yarn is not sufficient and efficient, resulting in poor elasticity and shaping effect after texturing. In order to address the technical problems existing in the prior art, a polyester yarn texturing machine is provided to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0024] The technical solution of the present invention will be further described in detail below with reference to specific embodiments:

[0025] For the first embodiment, please refer to... Figures 1-6 A polyester filament texturing machine includes an insulation box 1 and a heating box 3. Several heating sleeves 6 are installed at equal intervals inside the insulation box 1. Each heating sleeve 6 is equipped with a drying tube 7. The drying tube 7 and the heating sleeve 6 are internally connected through a connecting hole 19 opened on the side wall of the drying tube 7. Each drying tube 7 is connected to a guide tube 17. Two adjacent guide tubes 17 are connected through a bridge tube 22. Polyester filaments 5 pass through each drying tube 7. A heater 13 for heating the internal air is installed on the heating box 3. An air pump 21 connected to the heating box 3 is installed inside the insulation box 1. The outlet end of the air pump 21 is connected to the guide tube 17. An airflow circulation assembly is installed between the drying tube 7 and the heating box 3.

[0026] When texturing polyester filament 5 using this texturing machine, the polyester filament 5 is conveyed inside the drying tube 7. The air inside the heating chamber 3 is heated by the heater 13, and the hot air is drawn from the heating chamber 3 by the air pump 21. The hot air is conveyed along the guide tube 17 and the bridge tube 22, so that the hot air enters the interior of each heating sleeve 6. Then the hot air enters the drying tube 7 through the connecting hole 19, and finally the hot air heats the polyester filament 5 to achieve the elastic shaping effect of the polyester filament after texturing.

[0027] The airflow circulation assembly of this texturing machine includes a circulation box 4 fixed on the heat preservation box 1, each drying tube 7 extending into the interior of the circulation box 4 and communicating with the circulation box 4, and an airflow circulation pipe 12 connected between the circulation box 4 and the heating box 3, wherein the airflow circulation pipe 12 passes through the interior of the heat preservation box 1.

[0028] After the hot air enters the drying tube 7 and heats the polyester filament 5, it enters the circulation box 4. As the air pump 21 continuously draws air from the heating box 3, the pressure inside the heating box 3 is lower than the pressure inside the circulation box 4. The hot air inside the circulation box 4 will circulate back to the heating box 3 along the airflow circulation pipe 12 to replenish it, thus playing a secondary heating role. The air inside the heating box 3 heats up more quickly, making the heating temperature of the polyester filament 5 more stable and greatly improving the heating effect of the polyester filament 5.

[0029] During the process of the hot air inside the circulation box 4 circulating to the heating box 3 through the airflow circulation pipe 12, the hot air passes through the inside of the insulation box 1. That is, the part of the airflow circulation pipe 12 located inside the insulation box 1 can dissipate heat, which can raise the temperature of the insulation box 1 and further improve the insulation effect of the insulation box 1. It can effectively reduce the heat loss of the drying pipe 7, and at the same time realize the reuse of the waste heat of the hot air inside the circulation box 4, making the heating process of polyester yarn 5 of this texturing machine more energy-saving and efficient.

[0030] Second embodiment, please refer to Figures 1-6 In addition to the first embodiment, a filter box 10 is embedded and fixed inside the heating box 3. An air inlet pipe 23 located inside the heating box 3 is embedded and fixed on the side wall of the filter box 10. A mounting bracket 11 is installed on the top of the filter box 10, and several filter screens 24 inserted into the filter box 10 are fixed at the bottom of the mounting bracket 11. The filter screens 24 are arranged opposite to the air inlet pipe 23. A dust collection hopper 15 communicating with the filter box 10 is installed at the bottom of the filter box 10. The dust collection hopper 15 extends downward to the bottom of the heating box 3, and a base plate 16 is installed at the bottom of the dust collection hopper 15.

[0031] During the process of extracting hot air from the heating chamber 3 by the air pump 21, the hot air inside the heating chamber 3 enters the filter chamber 10 through the air inlet pipe 23. Then, the hot air passes through the filter screen 24 and enters the air pump 21, where it is pumped into the guide pipe 17. During this process, the hot air inside the heating chamber 3 can be filtered and purified, ensuring that the hot air wrapped in the polyester filament 5 is sufficiently pure, greatly reducing the pollution of the polyester filament 5 by dust, and preventing dust from accumulating and clogging the drying pipe 7.

[0032] Additionally, a rotating shaft I20 is rotatably installed inside the insulation box 1. Several auxiliary rotating wheels 18, each corresponding to a drying tube 7, are fixedly sleeved on the rotating shaft I20. Parts of the auxiliary rotating wheels 18 extend into the drying tube 7, and polyester filaments 5 pass around the auxiliary rotating wheels 18 and extend to the outside of the insulation box 1. A rotating shaft II25 is rotatably installed at the bottom of the insulation box 1. Several feed guide wheels 14, each corresponding to an auxiliary rotating wheel 18, are fixedly sleeved on the rotating shaft II25. A feed guide frame 9 is fixed on the insulation box 1, and polyester filaments 5 pass around the feed guide wheels 14 and through the feed guide frame 9. An auxiliary motor 2 is fixed to the side wall of the insulation box 1. The output shaft of the auxiliary motor 2 is coaxially fixed with the rotating shaft I20, and the rotating shaft I20 and rotating shaft II25 are connected by a belt pulley mechanism 8.

[0033] Based on the above structural configuration, during the conveying process of polyester filament 5, the auxiliary rotating wheel 18 and the feed guide wheel 14 guide the polyester filament 5, while the auxiliary motor 2 drives the rotating shaft I20 to rotate, thereby realizing the synchronous rotation of multiple auxiliary rotating wheels 18. At the same time, the rotating shaft I20 drives the rotating shaft II25 to rotate through the belt pulley mechanism 8, thereby realizing the synchronous rotation of multiple feed guide wheels 14. The feed guide wheel 14 and the auxiliary rotating wheel 18 rotate actively, and their linear speed is set to be the same as the conveying speed of the polyester filament 5. While guiding the polyester filament 5, the friction and scratching of the polyester filament 5 are reduced, which plays a good protective role for the polyester filament 5.

[0034] In summary, this invention, through the arrangement of multiple drying tubes 7 and a connecting pipe 17 communicating with the drying tubes 7, allows hot air to be filled into the narrow space of the drying tubes 7. This ensures that the polyester filaments 5 passing through the drying tubes 7 are fully enveloped by the hot air, while significantly reducing heat loss. Each polyester filament 5 is heated individually, resulting in more efficient heating and a significant improvement in the elasticity and shaping effect after texturing. Furthermore, the invention utilizes an airflow circulation pipe 12 to circulate the hot air inside the drying tubes 7 into the heating chamber 3 for secondary heating, avoiding direct heating of external cold air. The airflow circulation pipe 12 also passes through the insulation chamber 1, using its residual heat to insulate the chamber 1, greatly improving heat utilization efficiency and making the heating process of the polyester filaments 5 more efficient and energy-saving.
