Technical Field

[0001] This utility model relates to the field of spinning equipment technology, and in particular to an ITY hot roller box structure. Background Technology

[0002] ITY is a composite fiber made of POY and FDY fibers. Currently, ITY production uses FDY heated by hot rollers before laminating with POY. However, with process upgrades and improvements to product performance, it is necessary to heat the POY before lamination. This necessitates the use of a new type of hot roller box for heating and laminating POY and FDY, thus requiring the design of a novel hot roller box. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides an ITY hot roller box structure that can heat and composite POY and FDY using hot rollers to improve ITY performance.

[0004] This utility model discloses an ITY hot roller box structure, including a box body. A first yarn inlet is provided on one side of the top of the box body. A first yarn guide plate is provided inside the box body at the location corresponding to the first yarn inlet. A second yarn guide plate is provided inside the box body on the other side of the first yarn guide plate. A second yarn inlet is provided on the side of the top of the box body. A third yarn guide plate is provided inside the box body at the location corresponding to the second yarn inlet. The third yarn guide plate is located on the same side as the first yarn guide plate and is located below the first yarn guide plate. Three partitions are arranged at intervals in the box body below the third yarn guide plate, namely the first partition, the second partition, and the third partition. A first hot roller and a second hot roller are arranged at intervals in the box body between the first partition and the second partition. A third hot roller and a fourth hot roller are arranged at intervals in the box body between the second partition and the third partition. Below the third partition... The box contains a fourth guide plate; threading ports are provided at both ends of the first and second partitions, and a threading port is provided on the third partition. A thread outlet is provided on the side wall of the box below the third partition. POY yarn enters the box from the first inlet, passes around the first and second guide plates, passes through the threading ports on the first and second partitions, passes around the third and fourth hot rollers, passes through the threading port on the third partition, passes around the fourth guide plate, and finally exits from the thread outlet on the side of the box. FDY yarn enters the box from the second inlet, passes around the third guide plate, passes through the threading port on the first partition, passes around the first and second hot rollers, passes through the threading port on the second partition, passes around the third and fourth hot rollers, passes through the threading port on the third partition, passes around the fourth guide plate, and finally exits from the thread outlet on the side of the box.

[0005] A first suction shear is installed in the box between the first inlet and the first guide plate, and a second suction shear is installed in the box between the second inlet and the third guide plate. Two solenoid valves are installed on the outside of the box, respectively, and are installed on the pipes of the first and second suction shears. The two solenoid valves are electrically connected to the spinning controller and are synchronously controlled by the spinning controller.

[0006] A vertical slide rail is installed in the box between the first guide wire disc and the second guide wire disc. A slider is installed on the slide rail, and a wire guide is fixedly installed on the slider. The POY wire bundle passes through the wire guide. A positioning nut is installed on the slider to fix the slider to the slide rail.

[0009] A cooling opening is provided at the bottom of the housing corresponding to the fourth guide wire plate.

[0010] The ITY hot roller box structure obtained by this utility model has a first inlet and multiple guide discs at the top of the hot roller box, which allows POY fibers to be incorporated from the third hot roller. This enables the third and fourth hot rollers to heat and composite POY and FDY together, thereby improving the performance of the composite ITY and enhancing product quality. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figure 1As shown, this utility model discloses an ITY hot roller box structure, including a box body 1. A first yarn inlet 2 is provided on one side of the top of the box body 1. A first yarn guide plate 4 is provided inside the box body 1 at the location corresponding to the first yarn inlet 2. A second yarn guide plate 5 is provided inside the box body 1 on the other side of the first yarn guide plate 4. A second yarn inlet 3 is provided on the side of the top of the box body 1. A third yarn guide plate 6 is provided inside the box body 1 at the location corresponding to the second yarn inlet 3. The third yarn guide plate 6 is located on the same side as the first yarn guide plate 4, and... The third guide plate 6 is located below the first guide plate 4. Three partitions are spaced apart within the housing 1 below the third guide plate 6: a first partition 11, a second partition 12, and a third partition 13. A first heating roller 7 and a second heating roller 8 are spaced apart within the housing 1 between the first partition 11 and the second partition 12. A third heating roller 9 and a fourth heating roller 10 are spaced apart within the housing 1 between the second partition 12 and the third partition 13. A fourth guide plate is located within the housing 1 below the third partition 13. The housing 14 has threading ports 15 at both ends of the first partition 11 and the second partition 12, and a threading port 15 on the third partition 13. A thread outlet 16 is provided on the side wall of the housing 1 below the third partition 13. The POY yarn bundle 25 enters the housing 1 from the first inlet 2, passes around the first guide disc 4 and the second guide disc 5, passes through the threading ports 15 on the first partition 11 and the second partition 12, passes around the third hot roller 9 and the fourth hot roller 10, and then passes through the threading port 15 on the third partition 13. After passing the fourth guide roller 14, it is finally output from the outlet 16 on the side of the housing 1; the FDY filament 26 enters the housing 1 from the second inlet 3, passes through the threading port 15 on the first partition 11 after passing through the first hot roller 7 and the second hot roller 8 in sequence, passes through the threading port 15 on the second partition 12 in sequence, passes through the third hot roller 9 and the fourth hot roller 10 in sequence, passes through the threading port 15 on the third partition 13, passes through the fourth guide roller 14, and is finally output from the outlet 16 on the side of the housing 1.

[0015] Inside the housing 1, there are three partitions: a first partition 11, a second partition 12, and a third partition 13, which divide the interior of the housing 1 into four areas. The uppermost area is where POY yarn bundles 25 and FDY yarn bundles 26 are input, and they are guided by the first guide plate 4, the second guide plate 5, and the third guide plate 6 to ensure that the POY yarn bundles 25 and FDY yarn bundles 26 can be stably input and delivered to the required position. The first inlet 2 is located on the top right side of the housing 1. A first guide roller 4 is installed inside the housing 1 directly below it, and a second guide roller 5 is installed to the left of the first guide roller 4. Simultaneously, threading ports 15 are provided on the first partition 11 and the second partition 12 below the second guide roller 5. A third hot roller 9 and a fourth hot roller 10 are installed inside the housing 1 between the second partition 12 and the third partition 13. Therefore, the POY yarn bundle 25 enters the housing 1 through the first inlet 2, is conveyed to the left side via the first guide roller 4 and the second guide roller 5, and then vertically downwards through the two threading ports 15 before entering the third hot roller 9. A second inlet 3 is installed on the right side wall of the housing 1 above the first partition 1, and a third guide roller 6 is installed inside the housing 1 at the second inlet 3. Meanwhile, a first hot roller 7 and a second hot roller 8 are arranged in the housing 1 between the first partition 11 and the second partition 12. A threading port 15 is provided on the first partition 11 between the first hot roller 7 and the third guide plate 6, and a threading port 15 is provided on the second partition 12 between the second hot roller 8 and the third hot roller 9. Therefore, after the FDY filament bundle 26 enters the housing 1 from the second inlet 3, it passes through the third guide plate 6, then passes through the threading port 15, bypasses the first hot roller 7 and the second hot roller 8, and then passes through the threading port 15 to enter the third hot roller 9. At this time, the POY filament bundle 25 and the FDY filament bundle 26 are combined at the third hot roller 9. The combined filament bundle bypasses the fourth hot roller 10, passes through the threading port 15 of the third partition 13, enters the fourth guide plate 14, and finally exits from the outlet 16. FDY filament 26 is first heated by the first hot roller 7 and the second hot roller 8, and then combined with POY filament 25 at the third hot roller 9. After combination, the filaments are heated by the third hot roller 9 and the fourth hot roller 10 before entering the fourth guide plate 14 for final output. This process completes the heating and combination of POY filament 25 and FDY filament 26. FDY filament 26 is heated by four hot rollers, while POY filament 25 is heated by two hot rollers to meet process requirements. The first hot roller 7 and the second hot roller 8 between the first partition 11 and the second partition 12 only heat the FDY filament 26, and their heating temperature is controllable. The first partition 11 and the second partition 12 isolate the FDY filament 26, maintaining relatively controllable temperatures in other areas. The third hot roller 9 and the fourth hot roller 10 are located between the second partition 12 and the third partition 13, and their temperatures are also relatively controllable.Of course, the threading opening 15 is the connecting part between the first partition 11, the second partition 12, and the third partition 13. Although there is heat transfer, the diameter of the threading opening 15 is relatively small, so the heat transfer is minimal and does not affect the overall temperature of each area. The structure of the hot roller is a known existing structure, and will not be described in detail here, nor will it be specifically limited.

[0016] A first suction shear 21 is installed in the housing 1 between the first inlet 2 and the first guide plate 4, and a second suction shear 22 is installed in the housing 1 between the second inlet 3 and the third guide plate 6. Two solenoid valves 23 are installed on the outside of the housing 1. The two solenoid valves 23 are respectively installed on the pipes of the first suction shear 21 and the second suction shear 22. The two solenoid valves 23 are electrically connected to the spinning controller 24, and the solenoid valves 23 are synchronously controlled by the spinning controller 24.

[0017] The spinning controller 24 serves as the central control unit for the spinning equipment. All process parameters and operating conditions during the spinning process are transmitted to the spinning controller 24. Simultaneously, the spinning controller 24 can control the two solenoid valves 23 to operate synchronously. That is, when a yarn breakage occurs, the solenoid valve 23 activates, triggering the first suction shear 21 and the second suction shear 22 to work synchronously, cutting the FDY yarn bundle 26 and the POY yarn bundle 25. Workers must then re-spin the yarn to ensure the spinning quality of ITY. The suction shears are commercially available products; their specific structure will not be described or limited.

[0018] A vertical slide rail 18 is installed inside the housing 1 between the first guide wire disc 4 and the second guide wire disc 5. A slider 19 is installed on the slide rail 18, and a guide wire 20 is fixedly installed on the slider 19. The POY yarn bundle 25 passes through the guide wire 20. A positioning nut is installed on the slider 19 to fix the slider 19 to the slide rail 18. The guide wire 20 is a commercially available product, and its specific structure will not be described in detail. The guide wire 20 is fixed to the slider 19, and the slider 19 is connected to the slide rail 18, which is located between the first guide wire disc 4 and the second guide wire disc 5. The POY yarn bundle 25 output from the first guide wire disc 4 enters the second guide wire disc 5 after passing through the guide wire 20. At this time, the tension of the POY yarn bundle 25 can be adjusted by adjusting the height displacement of the slider 19 on the slide rail 18 according to the process parameters to meet the process requirements. Of course, in order to maintain the stability of the tension of the POY filament bundle 25 during operation, after adjusting the slider 19 to the appropriate position, the relative position of the slider 19 and the slide rail 18 is locked by the positioning nut, thereby keeping the position unchanged. The positioning nut is threaded onto the slider 19 and, when tightened, it can press against the slide rail 18, thereby locking the slider 19 and the slide rail 18 together.

[0019] The lowest point of the first guide plate 4 and the highest point of the second guide plate 5 are at the same horizontal level. With this setting, the POY filament bundle 25 between the first guide plate 4 and the second guide plate 5 can be kept in a horizontal conveying state under natural conditions. After being tensioned by the guide plate 20, the POY filament bundle 25 on both sides of the guide plate 20 is conveyed at a symmetrical angle, and the conveying process is stable and reliable.

[0020] The third hot roller 9 is located directly below the second guide plate 5. One threading port 15 on the first partition 11 and one threading port 15 on the second partition 12 are also located directly below the second guide plate 5. This configuration allows the POY filament bundle 25 to enter the third hot roller 9 vertically downwards from the second guide plate 5. The process is stable and reliable, without interference from the first partition 11 or the second partition 12. The operation is also more stable, reducing the need for guiding the POY filament bundle 25 and improving conveying stability.

[0021] A cooling opening 17 is provided at the bottom of the housing 1 at the location corresponding to the fourth guide wire plate 14.

[0022] Since the POY filament bundle 25 and FDY filament bundle 26 enter the fourth guide roller 14 after being heated by the hot roller, the ITY filament bundle formed at the fourth guide roller 14 has a high temperature. In order to reduce its temperature to a certain extent before entering the next process, a cooling opening 17 is provided at the bottom of the box 1 at the fourth guide roller 14 to allow the air outside the box 1 to communicate. When the ITY filament bundle passes through this point, it can come into contact with the outside air, thereby reducing its temperature and maintaining the stability of the ITY filament bundle, which meets the process requirements.
