Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, specifically a heat setting device for polyester low-elasticity yarn. Background Technology

[0002] Heat setting of polyester low-elasticity yarn is an important textile finishing process. It involves heating and cooling the yarn at a certain temperature to change its internal structure, thereby achieving the goals of stabilizing dimensions, improving elasticity, and enhancing hand feel and appearance.

[0003] In the current process of heat setting polyester low elasticity yarn, the spool containing the polyester low elasticity yarn is usually heated directly. Although the internal polyester low elasticity yarn can be heated through a relatively long heating time, the cooling rate of the internal polyester low elasticity yarn is slower. Since the cooling of the polyester low elasticity yarn needs to be maintained at a relatively fast rate, the heat setting effect of the internal polyester low elasticity yarn is poor, which affects the product quality.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-6 As shown, a heat-setting device for polyester low-elasticity yarn includes:

[0025] Mounting platform 4;

[0026] An unwinding mechanism is mounted on a mounting platform 4 and is used to unwind a spool 1 wound with polyester low-elasticity yarn 3.

[0027] A heat-setting mechanism is used to heat-set the released polyester low-elasticity yarn 3;

[0028] A winding mechanism is mounted on a mounting platform 4 and is used to wind up polyester low-elasticity yarn 3 that has undergone heat setting treatment.

[0029] Furthermore, the unwinding mechanism includes several unwinding units arranged on the mounting platform 4. Each unwinding unit includes a column 5, which is rotatably connected to the mounting platform 4. The outer surface of the column 5 is provided with a support plate 6, and it also includes a screw cap 7. The lower end of the screw cap 7 is provided with a stud 8, and the upper end of the column 5 is provided with a threaded hole that mates with the stud 8.

[0030] When installing the spool 1, it is necessary to first put the spool 1 on the column 5 and make the lower end of the spool 1 abut against the support plate 6. Then, the stud 8 of the screw cap 7 is engaged with the threaded hole of the column 5. At the same time, the height of the part of the column 5 above the support plate 6 is lower than the height of the spool 1. Therefore, the screw cap 7 can abut against the upper end of the spool 1 during rotation. Through the cooperation with the support plate 6, the spool 1 is fixed between the screw cap 7 and the support plate 6. The column 5 and the mounting platform 4 are connected by a bearing. When the winding mechanism pulls out the polyester low elastic yarn 3 wound on the spool 1, the spool 1 and the column 5 can rotate at the same time.

[0031] Furthermore, the heat-setting mechanism includes a vertical plate 9 mounted on the mounting platform 4, a rotating shaft 10 mounted on the vertical plate 9, and a sleeve 11 mounted on the outer surface of the rotating shaft 10. An electric heating tube 12 is mounted on the vertical plate 9, located inside the sleeve 11 but not in contact with the sleeve 11 or the rotating shaft 10. A cooling chamber 13 is mounted on the vertical plate 9 and rotatably connected to the vertical plate 9. One end of the cooling chamber 13 is open. A water storage tank 14 is mounted on the mounting platform 4, and a water pump 15 is mounted on the water storage tank 14. A sealing plug 16 is provided at the outlet end of the water pump 15. The sealing plug 16 is rotatably connected to the cooling chamber 13. The sealing plug 16 is provided with a water outlet pipe 17 and a water return pipe 18. The water return pipe 18 is connected to the water storage tank 14. The rotating shaft 10 and the cooling chamber 13 are driven by a synchronous pulley 19 and a synchronous belt 20. The upright plate 9 is provided with a fixing plate 21. A motor 22 for driving the rotating shaft 10 is provided on one side of the fixing plate 21. Three sets of wire units are provided on one side of the upright plate 9. The three sets of wire units are respectively provided on both sides and the middle of the upright plate 9. The wire unit includes a support frame 23. Several guide rings 24 are provided on the support frame 23.

[0032] The heat setting mechanism consists of two parts: a heating part for the polyester low elastic yarn 3 and a cooling part. When heat setting the polyester low elastic yarn 3, it is necessary to first heat the polyester low elastic yarn 3 and then cool the heated polyester low elastic yarn 3 to achieve the heat setting treatment of the polyester low elastic yarn 3.

[0033] Regarding the heating part in the heat setting mechanism, the electric heating tube 12 is located inside the sleeve 11. The sleeve 11 is made of stainless steel with a wall thickness of 2mm. After the electric heating tube 12 is energized, it can heat the inner wall of the sleeve 11 and raise the overall temperature of the sleeve 11. It is necessary to control the surface temperature of the sleeve 11 to 150℃ to 160℃. This can be achieved by setting a corresponding temperature control module to detect the temperature of the sleeve 11 and adjust the heating power and heating time of the electric heating tube 12 so that the sleeve 11 can be maintained within this temperature range. The sleeve 11 is fixed to the rotating shaft 10 by bolts.

[0034] Regarding the cooling section of the heat setting mechanism, the water tank 14 stores cooling water treated by a refrigeration device. The temperature of the cooling water is below 6°C. A refrigeration module can be built into the water tank 14 to maintain the water in the water tank 14 at a low temperature, ensuring the cooling effect of the cooling chamber 13. The cooling chamber 13 is made of stainless steel with a wall thickness of 2mm. The sealing plug 16 is located inside the cooling chamber 13 and is rotatably connected to the cooling chamber 13. The sealing plug 16 is fixed to the water pump 15, allowing the cooling chamber 13 to rotate. The sealing plug 16 needs to remain relatively stationary with the water pump 15. The water pump 15 pumps water through the outlet pipe 17 in the sealing plug 16 to... Cooling water is supplied to the cooling chamber 13. The end of the outlet pipe 17 away from the sealing plug 16 extends into the interior of the cooling chamber 13. As the amount of cooling water inside the cooling chamber 13 increases, the cooling water can flow back to the storage tank 14 through the return pipe 18. A pressure valve can be installed between the return pipe 18 and the storage tank 14. Only when the rated pressure is applied can the cooling water in the cooling chamber 13 flow back to the storage tank 14 through the return pipe 18 and the pressure valve, ensuring that the cooling chamber 13 is filled with cooling water. By setting the length of the outlet pipe 17 and the return pipe 18, the cooling water can flow relatively fully in the cooling chamber 13 before flowing back to the storage tank 14 through the return pipe 18.

[0035] The polyester low-elasticity yarn 3 released from the spool 1 on column 5 first passes through the first set of guide rings 24, then passes under the sleeve 11, then wraps around the sleeve 11 once, then passes through the second set of guide rings 24, then passes under the cooling chamber 13, then wraps around the cooling chamber 13 once, then passes through the third set of guide rings 24. The winding mechanism then winds up the polyester low-elasticity yarn 3. When the winding mechanism moves the polyester low-elasticity yarn 3, the motor 22 needs to be started. The motor 22 drives the rotating shaft 10 and the sleeve 11 to rotate. Simultaneously, through the cooperation of the synchronous pulley 19 and the synchronous belt 20, the cooling chamber 13 rotates synchronously with the sleeve 11. The outer diameters of the sleeve 11 and the cooling chamber 13 are... Similarly, the rotational speeds of both remain the same within the allowable error range. At the same time, when the polyester low-elasticity yarn 3 passes over the surfaces of the sleeve 11 and the cooling chamber 13, the moving speed of the polyester low-elasticity yarn 3 is adapted to the rotational speed of the sleeve 11 and the cooling chamber 13 within the allowable error range, thereby reducing the friction between the polyester low-elasticity yarn 3 and the sleeve 11 and the cooling chamber 13 to protect the polyester low-elasticity yarn 3. At the same time, when any position of the polyester low-elasticity yarn 3 passes over the sleeve 11, it needs to maintain continuous contact with the sleeve 11 for a period of 10s-15s to ensure that the polyester low-elasticity yarn 3 can be effectively heated. The contact time between the cooling chamber 13 and the polyester low-elasticity yarn 3 is also between 10s-15s to ensure that the heated polyester low-elasticity yarn 3 can be cooled down relatively effectively.

[0036] When the sleeve 11 and the cooling chamber 13 rotate, the electric heating tube 12, the sealing plug 16, the water outlet pipe 17, and the water return pipe 18 are all in a stationary state. Although heating and cooling are in operation, their positions will not change significantly with the sleeve 11 and the cooling chamber 13.

[0037] Furthermore, the upright plate 9 is provided with two side plates 25, and a horizontal plate 26 is provided between the two side plates 25. A guide post 27 is provided on the horizontal plate 26, and a spring 28 is sleeved on the guide post 27. Two fixing rods 29 are provided on the lower surface of the horizontal plate 26. The fixing rods 29 are slidably connected to the side plate 25 below. A mounting bracket 30 is provided at the lower end of the two fixing rods 29, and a roller 31 is provided on the mounting bracket 30.

[0038] The spring 28 continuously presses the roller 31 onto the timing belt 20, keeping the timing belt 20 taut and ensuring accurate engagement between the timing pulley 19 and the timing belt 20.

[0039] Furthermore, the winding mechanism includes several winding units mounted on the mounting platform 4. Each winding unit includes a vertical rod 32. A core cylinder 2 for winding polyester low-elasticity yarn 3 is sleeved on the vertical rod 5. The vertical rod 32 is rotatably connected to the mounting platform 4. All vertical rods 32, located below the mounting platform 4, have meshing gears 33 at their lower ends. A second motor 34 for driving one of the vertical rods 32 to rotate is located below the mounting platform 4. A base plate 35 is mounted on the vertical rod 32. A second rotating cap 36 is also included. The lower surface is provided with a stud 37, and the upright 32 is provided with a threaded hole 2 that mates with the stud 37. The lower surface of the mounting platform 4 is provided with a fixing frame 38, and the fixing frame 38 is provided with a reciprocating ball screw 39. The fixing frame 38 is provided with a motor 40 for driving the ball screw 39 to rotate. The ball screw 39 is provided with a slide 41, and a long plate 42 is provided on one side of the slide 41. A crossbar 43 is provided on the long plate 42, and a plurality of guide rings 44 are provided on the upper surface of the crossbar 43.

[0040] Before winding the polyester low-elasticity yarn 3, one end of the polyester low-elasticity yarn 3 needs to be passed through the guide ring 44. Then, the core cylinder 2 is installed on the upright 32. Next, by rotating the second screw cap 36, the core cylinder 2 is fixed between the base plate 35 and the second screw cap 36 through the threaded connection between the second stud 37 and the second threaded hole. After the installation of the core cylinder 2 is completed, the polyester low-elasticity yarn 3 is wound and fixed on the core cylinder 2. Then, the second motor 34 is started. The second motor 34 drives one of the uprights 32 to rotate. Through the meshing of the gear 33 with the other gears 33, it can drive all the uprights 32 to rotate. When the uprights 32 rotate, they can drive all the core cylinders 2 to rotate, thereby winding the polyester low-elasticity yarn 3.

[0041] When winding up the polyester low-elasticity yarn 3, the motor 40 needs to be started at the same time. The motor 40 drives the ball screw 39 to rotate. Since the ball screw 39 is reciprocating, it can drive the slide 41 to move up and down on the fixed frame 38, thereby driving the long plate 42, the crossbar 43 and the guide ring 44 to move up and down. This allows the height of the polyester low-elasticity yarn 3 supplied to the core cylinder 2 to be adjusted so that the polyester low-elasticity yarn 3 can be wound onto the core cylinder 2 in a reasonable manner.

[0042] In addition to heat setting polyester low-elasticity yarn 3, this heat setting device can also perform heat setting treatment on yarns of other materials. The temperature, time and other parameters of the treatment can be adjusted according to the corresponding yarn.

[0043] All spools 1 have roughly the same length to ensure that the winding progress of all core spools 2 remains roughly the same, which also makes it convenient to process spools 1 in batches.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
