Description

Technical Field

[0001] This utility model belongs to the field of polyester filament processing technology, specifically relating to a device for uniform traction adjustment of elastic polyester filament. Background Technology

[0002] Elastic polyester filament, also known as elastic yarn, is a synthetic fiber made from a blend of polyester and elastic fibers. It is known for its high elasticity and durability and is widely used in the manufacture of various products.

[0003] During the processing of elastic polyester yarn, traction is required. To prevent the current situation where multiple polyester yarns are pulled side by side, which can easily cause confusion between the polyester yarns and affect the traction effect, Chinese patent document CN 218989554 U discloses a device for uniform traction force in polyester yarn production. The device includes a fixed base 1, a fixed plate 2, a fixed shaft 3, a traction roller 4, a limiting mechanism, and a height adjustment mechanism. The fixed base 1 is fixedly connected to the top side surface of the fixed plate 2, and the fixed shaft 3 is fixedly connected to the top side surface of the fixed plate 2. The traction roller 4 is rotatably sleeved on the surface of the fixed shaft 3. The traction roller 4 has a traction groove 401 on its surface. The polyester yarn is placed in the traction groove 401 on the surface of the traction roller 4. The traction roller 9 presses down on the top side of the traction roller 4, which facilitates the uniform placement of the polyester yarn at equal intervals, thereby improving the uniform distribution of the traction process in polyester yarn production.

[0004] However, the above technical solution has the following drawbacks: 1. During the polyester filament traction process, friction will occur between the polyester filament and the traction groove. After the traction groove wears out, the entire traction roller needs to be replaced, which is costly; 2. There are many different diameter sizes of polyester filaments. The design of the fixed-size traction groove is not conducive to traction of polyester filaments of different sizes; 3. The polyester filament will heat up after friction with the traction roller and the limit roller. When the temperature is high, it will affect the processing quality of the polyester filament.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides a device for uniformly traction and adjusting elastic polyester yarn, including a traction roller 1 and an adjusting and limiting roller 2. Two traction rollers 1 are provided, and the adjusting and limiting roller 2 is located between the two traction rollers 1. The adjusting and limiting roller 2 is equipped with multiple evenly spaced ring plates 3. The ring plates 3 are mounted on the adjusting and limiting roller 2 by a positioning mechanism. The outer edge of the ring plate 3 is provided with an annular limiting groove 4. Multiple polyester yarns 5 pass through the annular limiting groove 4 below each ring plate 3 and are pressed above the two traction rollers 1 for traction. The adjusting limit roller 2 is connected to an external lifting and adjusting mechanism via a connecting frame 6. During traction, multiple polyester filaments 5 pass through the annular limiting groove 4 below each ring plate 3 and are pressed above the two traction rollers 1 for traction. The adjusting limit roller 2 is connected to an external conventional lifting and adjusting mechanism via a connecting frame 6. By driving the adjusting limit roller 2 to rise and fall, the polyester filaments 5 are further elastically adjusted during traction. During this period, multiple spaced ring plates 3 and annular limiting grooves 4 evenly space a row of polyester filaments, improving the uniform distribution of polyester filaments during the traction process.

[0025] Specifically, the connecting frame 6 is rotatably connected to the shafts on both sides of the traction roller 1 via bearings; in this embodiment, the adjusting limit roller 2 is connected to an external conventional lifting and adjusting mechanism via the connecting frame 6, so that when the connecting frame 6 drives the adjusting limit roller 2 to rise and fall, it does not interfere with its rotation.

[0026] Specifically, the adjusting and limiting roller 2 includes a circular roller body 7. The outer wall of the circular roller body 7 is provided with a plurality of positioning grooves 8 corresponding to the ring piece 3. Four positioning grooves 8 are spaced around the circular roller body 7. Each of the four positioning grooves 8 is equipped with an elastic element 9 and a positioning shaft 10. The positioning shaft 10 is seamlessly and smoothly attached to the inner wall of the positioning groove 8. The inner wall of the ring piece 3 is provided with a slot 11 corresponding to the positioning groove 8. The positioning shaft 10 is partially locked in the slot 11. In this embodiment, the positioning shaft 10 is locked in the slot 11 under the pressure of the elastic element 9, which fully positions the ring piece 3. During installation, multiple ring pieces 3 are placed on the circular roller body 7 and then positioned on one side of the positioning groove 8. The circular roller body 7 is fixed on the end plate 12. Then, the elastic element 9 and the positioning shaft 10 are installed in a set of positioning grooves 8. The positioning shaft 10 is pressed into the positioning groove 8 and then the ring piece 3 is moved into place. The positioning shaft 10 will automatically enter the slot 11 and lock.

[0027] Specifically, the central part of the roller body 7 is a hollow structure, and end plates 12 are installed at both ends of the roller body 7. The end plates 12 are connected to the shaft tubes 13. The end plates 12 and the roller body 7 are fixedly connected by positioning screws 14. The inner wall of the roller body 7 is provided with through holes 15 that pass through each of the positioning grooves 8. In this embodiment, the ring pieces 3 can be installed and removed from the roller body 7. Specifically, the regulating valve 18 is closed on one side through the air pipes on both sides, and then the air pipe 17 at the other end is connected to the suction device, thereby generating negative pressure suction inside the roller body 7. Further through the through holes 15, the positioning shaft 10 is forced inward by the negative pressure suction to fully push the elastic element 9 into the positioning groove 8, so that all the ring pieces 3 are disengaged from the limit. The ring pieces 3 can be removed, and then the elastic element 9 and the positioning shaft 10 are taken out. Then the positioning screws 14 are removed, and the roller body 7 and the ring pieces 3 can be disassembled as a whole.

[0028] Specifically, a rotary joint 16 is installed at the head end of each of the two shaft tubes 13, and the rotary joint 16 is connected to the air pipe 17. In this embodiment, during traction adjustment, the air outlet and air inlet of the external conventional cold air circulation mechanism are connected through the air pipes 17 on both sides, and the regulating valve 18 is opened to complete the continuous cooling of the roller body 7 and the ring plate 3, thereby providing cooling during the traction adjustment process of the polyester yarn 5 and improving the processing quality of the polyester yarn. The rotary joint 16 is set so that the cooling mechanism does not affect the rotation of the roller body 7.

[0029] Specifically, each of the air tubes 17 is equipped with a regulating valve 18; in this embodiment, the regulating valve 18 facilitates the adjustment and switching of the flow rate of the air tubes 17 on both sides.

[0030] Specifically, the head end of the positioning shaft 10 is a tapered head structure; in this embodiment, the positioning shaft 10 is set to facilitate the automatic entry of the positioning shaft 10 into the slot 11.

[0031] Specifically, a corresponding annular sealing groove is provided between the end edge of the roller body 7 and the end plate 12, and an annular sealing ring 19 is installed in the annular sealing groove; in this embodiment, the sealing performance at the connection between the roller body 7 and the end plate 12 can be improved by setting the annular sealing ring 19.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] Working principle: During traction, multiple polyester filaments 5 pass through the annular limiting grooves 4 below each ring plate 3, pressing against the two traction rollers 1 for traction. The adjusting limiting rollers 2 are connected to an external conventional lifting and adjusting mechanism via the connecting frame 6. By driving the adjusting limiting rollers 2 to rise and fall, the traction of the polyester filaments 5 is further elastically adjusted. During this process, multiple spaced ring plates 3 and annular limiting grooves 4 evenly space a row of polyester filaments, improving the uniform distribution of polyester filaments during the traction process. At the same time, the ring plates 3 can be installed and removed from the cylindrical roller body 7. Specifically, the regulating valve 18 is closed on one side through the air pipes on both sides, and then the air pipe 17 at the other end is connected to a suction device, thereby generating negative pressure suction inside the cylindrical roller body 7. This suction further passes through the through hole 15, causing the positioning shaft 10 to be squeezed inward under negative pressure suction. The elastic element 9 fully enters the positioning groove 8, thereby disengaging all the ring pieces 3 from the limit position. The ring pieces 3 can be removed, and then the elastic element 9 and positioning shaft 10 can be taken out. After removing the positioning screw 14, the roller body 7 and the ring pieces 3 can be disassembled as a whole. This allows the ring piece 3 to be replaced when a ring limiting groove 4 is worn, saving costs. At the same time, the ring pieces 3 of different ring limiting grooves 4 can be designed according to the different sizes of polyester yarns, and can be replaced on the roller body 7 accordingly to meet the traction of polyester yarns of different sizes. During traction adjustment, the outlet and inlet of the external conventional cold air circulation mechanism are connected through the air pipes 17 on both sides. By opening the regulating valve 18, the roller body 7 and the ring pieces 3 can be continuously cooled, thereby providing cooling for the polyester yarn 5 during the traction adjustment process and improving the processing quality of the polyester yarn.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
