[0023] like Figures 1 to 3 As shown, a TMT type texturing machine head lifting gun to winding section tow pulling tool comprises a connecting tube 5, a detachable air suction gun tube 1 arranged at the front end of the connecting tube 5, and an air inlet pipe 3 arranged at one side of the connecting tube 5. The connecting tube 5 is provided with an air inlet cavity 2 and an air outlet cavity 6 arranged in a stepped hole. The connecting tube 5 is provided with an air flow guide tube 11 with a diameter smaller than that of the air inlet cavity 2. One end of the air flow guide tube 11 is connected to and blocked with the air suction gun tube 1. The two ends of the air inlet cavity 2 are respectively connected to the air suction gun tube 1 and the air flow guide tube 1. The tube 11 is blocked to form a sealed cavity, a guide air hole 14 is provided on the air flow guide tube 11, a drainage tube 12 with a diameter smaller than the inner diameter of the air flow guide tube 11 is provided at the end of the air suction gun tube 1, a circular guide groove 13 is formed between the drainage tube 12 and the air flow guide tube 11, one end of the guide groove 13 is connected with the air outlet cavity 6 through the inner hole of the air flow guide tube 11, and the gas injected from the air inlet pipe 3 passes through the air inlet cavity 2, the guide air hole 14 and the guide groove 13 in sequence and is discharged from the end of the air outlet cavity 6.

[0024] The air inlet cavity 2 and the air outlet cavity 6 inside the connecting tube 5 are arranged in a coaxial stepped hole. In the actual assembly process, the air flow guide tube 11 is placed in the air inlet cavity 2 of the connecting tube 5, and then one end of the air suction gun tube 1 is inserted into the air inlet cavity 2 of the connecting tube 5, and the drainage tube 12 is inserted into the air flow guide tube 11, and then the air suction gun tube 1 and the connecting tube 5 are connected and sealed and fixed. At this time, the two ends of the air inlet cavity 2 are blocked by the air suction gun tube 1 and the air flow guide tube 11 to form a sealed cavity that can only be exhausted through the guide air hole 14. At the same time, the drainage tube 12 and the air flow guide tube 11 form a guide groove 13 structure with one end blocked. Then the waste silk bag is installed at the end of the connecting tube 5, and the external air pipe is connected to the end of the air inlet pipe 3. When in use, start the air pump to blow air into the air intake pipe 3, and the gas enters the air intake chamber 2 through the air intake pipe 3. The air in the air intake chamber 2 then enters the guide groove 13 through the guide air hole 14 to form high-pressure gas. Through the sealing structure on one side of the guide groove 13, the generated high-pressure gas is discharged along one end of the guide groove 13 to the end of the air outlet chamber 6. In the process of the gas being discharged along the air outlet chamber 6, a negative pressure airflow is formed in the air suction gun tube 1, so that the front end of the air suction gun tube 1 can suck the filament bundle into the air suction gun tube 1 when pulling the filament bundle. The entire structure of the head lifting gun to the winding tool is simple, the replacement cost of each component is low, and it is not easy to block the internal gas, which greatly improves the operation and maintenance efficiency and is more conducive to popularization and use.

[0025] As a further improvement, the air intake pipe 3 is arranged in an L shape, and a support rod 4 is arranged between the air intake pipe 3 and the connecting pipe 5 .

[0026] The air intake pipe 3 is arranged in an L shape, which can make the air inlet of the air intake pipe 3 away from the connecting pipe 5, so as to facilitate the connection of the air intake pipe 3. Since the air intake pipe 3 is generally a metal pipe with a diameter of about 8 mm and only one end is welded and fixed, it is easy to separate, especially when the length is large, it is easy to separate from the connecting pipe 5. Therefore, a support rod 4 is added between the air intake pipe 3 and the connecting pipe 5. The support rod 4 can not only support and stabilize the air intake pipe 3, but also form a hand-held structure, which is convenient for the operator to hold it while working.

[0027] As a further improvement, a plurality of outwardly protruding convex rings 8 are provided at the end of the connecting tube 5 , and a tightening groove 7 is formed between two adjacent convex rings 8 , and a waste silk bag for collecting waste silk is prevented from falling off by the convex rings 8 .

[0028] When the traction tool is pulling the wire bundle from the TMT type texturizing machine's lifting head and pulling gun to the winding section, waste wire will inevitably be generated, and the waste wire will flow out from the end of the connecting tube 5. Therefore, a waste wire bag is generally put on to facilitate the collection of waste wire. However, since the wind force becomes stronger after the size of the entire device is changed, in order to ensure that the waste wire bag can be firmly installed and fixed, a plurality of outwardly protruding convex rings 8 are formed at the end of the connecting tube 5, and a tightening groove 7 is formed between two adjacent convex rings 8. When the bag mouth is put on the end of the connecting tube 5, it can be fixed by a cable tie, a clamp, etc., and then embedded in the tightening groove 7, so that the convex ring 8 at the rear end can effectively prevent the bag and the fastener from falling off.

[0029] As a further improvement, a threaded tube 17 is provided at one end of the suction gun tube 1, an external hexagonal rotating portion 16 is also provided on the suction gun tube 1, and the connecting tube 5 and the suction gun tube 1 are connected by threads.

[0030] One end of the suction gun tube 1 is connected to the connecting tube 5 through a threaded tube 17, which is convenient for disassembly and assembly, and can also play a sealing role, and the structure is simpler, especially an outwardly protruding external hexagonal rotating portion 16 is formed on one side of the threaded tube 17. The external hexagonal rotating portion 16 can facilitate disassembly and assembly with tools such as wrenches, avoiding the problem of being unable to tighten or disassemble.

[0031] As a further improvement, two guide holes 14 are provided on the airflow guide tube 11 , and the two guide holes 14 are symmetrically and staggeredly arranged; the curvature of the guide holes 14 is 130-180°.

[0032] Two symmetrical and staggered guide air holes 14 are formed on the air flow guide tube 11, which can make the air flow more even when entering the guide groove 13, and the curvature of the guide air hole 14 is 130-180°, which can ensure that the air flow enters more smoothly, especially when the curvature of the guide air hole 14 is 180°, the gas entering the guide groove 13 can be distributed in a circular ring shape, so that there will be no blockage problem during the intake process.

[0033] As a further improvement, a rearwardly extending limit tube 10 is provided at one end of the airflow guide tube 11, the limit tube 10 extends into the air outlet cavity 6, and the inner diameter of the limit tube 10 is consistent with the inner diameter of the airflow guide tube 11; a guide portion 9 is also provided at the outer end of the limit tube 10.

[0034] The diameter of the limiting tube 10 is less than or equal to the inner diameter of the air outlet cavity 6. When the airflow guide tube 11 is installed in the connecting tube 5, it can play a role of limiting and guiding after being inserted into the air outlet cavity 6 through the limiting tube 10, so as to avoid the problem of the airflow guide tube 11 shaking left and right and causing poor air outlet. Since the outer diameter of the limiting tube 10 is basically the same as the diameter of the air outlet cavity 6, in order to enable it to be quickly inserted into the air outlet cavity 6, a guide portion 9 is formed at the end of the limiting tube 10 by reducing the outer diameter. The entire airflow guide tube 11, the limiting tube 10 and the guide portion 9 are integrally formed with a metal tube, which has a longer service life and is less prone to damage during use.

[0035] As a further improvement, a sealing tube 15 with an inclined outer end surface is provided between the drainage tube 12 and the air suction gun tube 1 , and one end of the airflow guide tube 11 is inserted and sealed through the sealing tube 15 .

[0036] During installation, when the suction gun tube 1 is inserted into the connecting tube 5, the drainage tube 12 is first inserted into the airflow guide tube 11 due to its smallest diameter, and then the sealing tube 15 is inserted into the airflow guide tube 11 again during the process of continuing to be tightened inwardly by the threaded tube 17, so that the sealing tube 15 forms a slow push-close between the ports of the airflow guide tube 11. When the suction gun tube 1 cannot be screwed in further after being pressed to seal, it can achieve automatic tensioning and blocking. At the same time, one end of the connecting tube 5 is sealed by the threaded tube 17. Through the combination of the threaded tube 17 and the sealing tube 15, when the sealing tube 15 and the airflow guide tube 11 are worn due to multiple combinations, the sealing effect can be timely compensated by controlling the depth of the thread, avoiding the problem of poor sealing between the airflow guide tube 11 and the sealing tube 15. The suction gun tube 1 with the sealing tube 15 is made of stainless steel as a whole, which has higher firmness and longer service life.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
