Description

Technical Field

[0001] This utility model relates to the field of spandex yarn production technology, and in particular to a spandex yarn conveying insulation and moisture retention pipe. Background Technology

[0002] In the processing of spandex yarn, processes such as core-spun yarn, drafting, and steaming require heat and moisture preservation. When transporting spandex yarn between these processes, it needs to be transported through heat-preserving and moisture-preserving pipelines to prevent external environmental factors from affecting its humidity and temperature, which would ultimately affect the performance of the spandex yarn.

[0003] Because spandex yarn has excellent elasticity, when it is transported in a pipeline, the elasticity of the spandex yarn changes, which affects the tension of the spandex yarn. This causes the spandex yarn to bounce due to changes in tension during transport, affecting the transport stability of the spandex yarn. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a heat-insulating and moisture-retaining pipeline for conveying spandex yarn, so as to solve the problem that spandex yarn is prone to bouncing due to changes in tension, which affects the conveying stability of spandex yarn.

[0005] To achieve the above objectives, this utility model provides a spandex yarn conveying, heat-insulating, and moisture-retaining pipe, including a support base, and the pipe further includes:

[0006] The guide tube located in front of the support base includes a flexible bend and rigid tubes at the bottom ends of both ends of the flexible bend.

[0007] A limiting sleeve is provided on the rigid tube, and a force-applying part connects the limiting sleeve and the support base. The force-applying part is used to apply an external force to at least one limiting sleeve to bend the flexible tube and change the angle between the two rigid tubes.

[0008] A delivery pipe connected to the guide pipe, the delivery pipe being used to deliver water vapor.

[0009] Preferably, the force-applying part includes:

[0010] The slider is slidably connected to the groove provided on the support base.

[0011] The movable frames are arranged opposite to each other on both sides of the support base. The movable frames correspond to the limiting sleeves. The movable frames include movable rods with their ends hinged to each other and support blocks fixedly connected to the corresponding limiting sleeves. The support blocks are fixedly mounted on one of the movable rods. The movable rods correspond to the sliders, and the other end of the movable rods is hinged to the corresponding sliders.

[0012] A drive structure for moving the two sliders closer together or further apart.

[0013] Preferably, the driving structure includes:

[0014] The bottom end of the slider is rotatably connected to the bottom of the slide groove. The slider is provided with threaded holes, and the threads of the two threaded holes are in opposite directions.

[0015] A drive component for driving the rotation of the threaded rod.

[0016] Preferably, the driving component is a rotating wheel, and the top end of the threaded rod passes through the top of the groove and is fixed at the center of the rotating wheel.

[0017] Preferably, the driving component is a motor fixedly mounted on the support base, and the output end of the motor is fixedly connected to the top end of the threaded rod.

[0018] Preferably, the two movable frames are joined together to form a rhombus, and the flexible bend is fixedly sleeved in the middle of the two limiting sleeves.

[0019] Preferably, the rigid tube includes a straight tube fixed at one end of the flexible bend and an extension tube inserted into one end of the straight tube. A threaded sleeve is threadedly installed between the extension tube and the straight tube. The threaded sleeve is used to fix the overlapping part of the extension tube and the straight tube after the extension tube is pulled out or pushed in axially for a certain distance. The threads on the outside of the straight tube and the extension tube are in the same direction.

[0020] Preferably, the threaded sleeve is movably sleeved on the outside of the extension tube, and the axial length of the thread on the outside of the straight tube is less than the axial length of the threaded sleeve.

[0021] The beneficial effects of this utility model are:

[0022] This invention uses a control adjustment unit to drive two support blocks and a limiting sleeve to move closer or further apart, thereby adjusting the bending angle of the flexible bend tube. By adjusting the vertical arch height of the flexible bend tube's bending point, the tension on the spandex yarn can be adjusted. This allows for timely increase in tension on the spandex yarn when it bounces, improving the stability of the spandex yarn transport and preventing tangling due to large bounces during transport. Furthermore, by adjusting the combined length of the extension tube and the flexible bend tube according to usage requirements, the minimum tension limit on the spandex yarn can be adjusted, thus expanding the tension adjustment range to accommodate the transport of spandex yarns of different specifications.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0032] like Figures 1 to 4 As shown, a spandex yarn conveying insulation and moisture-retaining pipe includes a support base 1, and the pipe also includes:

[0033] The guide tube 2 is located in front of the support base 1. The guide tube 2 includes a flexible bend 21 and rigid tubes 22 located at the bottom ends of both ends of the flexible bend 21.

[0034] The limiting sleeve 3 is provided on the rigid tube 22 and the force-applying part 4 connects the limiting sleeve 3 and the support seat 1. The force-applying part 4 is used to apply external force to at least one limiting sleeve 3 to bend the flexible tube 21 so as to change the angle between the two rigid tubes 22.

[0035] The conveying pipe 5 is connected to the guide pipe 2 and is used to convey water vapor. The end of the conveying pipe 5 away from the guide pipe 2 is connected to a steam generator. The output end of the steam generator is equipped with a solenoid valve. The steam generator heats the water pumped into it to boiling point, turning it into water vapor. As the amount of water vapor increases, the air pressure inside the steam generator increases. Under the action of the air pressure difference, the water vapor flows into the guide pipe 2 through the conveying pipe 5 to maintain the humidity and temperature inside the guide pipe 2. The guide pipe 2 is equipped with a temperature and humidity detector to detect the internal temperature and humidity, so as to monitor the temperature and humidity inside the guide pipe 2 in real time. By controlling the flow rate of water vapor delivered into the guide pipe 2, the temperature and humidity inside the guide pipe 2 can be controlled within a suitable range to avoid the temperature and humidity being too low or too high, which would affect the performance of the spandex yarn.

[0036] like Figures 2 to 4 As shown, the force-applying part 4 includes:

[0037] The slider 41 is slidably connected to the groove 42 on the support base 1.

[0038] The movable frame 43 is arranged on both sides of the support base 1. The movable frame 43 corresponds to the limiting sleeve 3. The movable frame 43 includes a movable rod 431 with its ends hinged to each other and a support block 432 fixedly connected to the corresponding limiting sleeve 3. The support block 432 is fixedly mounted on one of the movable rods 431. The movable rod 431 corresponds to the slider 41, and the other end of the movable rod 431 is hinged to the corresponding slider 41.

[0039] A drive structure 44 for driving two sliders 41 to move closer or further apart.

[0040] By driving the two sliders to move closer or further apart vertically through the drive structure 44, the angle between the two rigid tubes 22 can be increased or decreased, thereby adjusting the arch height of the bending point of the flexible tube 21. Ultimately, this adjusts the tension on the spandex yarn. When the spandex yarn bounces, the tension on the spandex yarn can be increased to suppress the bounce and improve the conveying stability of the spandex yarn.

[0041] like Figure 3 and Figure 4 As shown, the drive structure 44 includes:

[0042] The bottom end of the threaded rod 441 is rotatably connected to the bottom of the slide 42. The slider 41 is provided with a threaded hole 442, and the threads of the two threaded holes 442 are opposite.

[0043] The drive component 443 is used to drive the threaded rod 441 to rotate. By controlling the drive component 443 to drive the threaded rod 441 to rotate clockwise or counterclockwise, the two sliders 41 are driven to move closer or further apart, thereby adjusting the distance between the two movable frames 43 in the lateral direction. This allows for adjustment of the bending point of the flexible bend tube 21, thereby adjusting the tension on the spandex yarn.

[0044] like Figure 2 and Figure 3 As shown, the driving component 443 is a rotating wheel, and the top end of the threaded rod 441 passes through the top of the slide groove 42 and is fixed at the center of the rotating wheel. The rotating wheel can be manually turned to drive the threaded rod 441 to rotate synchronously, thereby adjusting the tension of the spandex yarn.

[0045] like Figure 4 As shown, the driving component 443 is a motor fixedly mounted on the support base 1. The output end of the motor is fixedly connected to the top end of the threaded rod 441. In this way, the threaded rod 441 can be driven to rotate by controlling the motor, thereby realizing mechanized drive and improving the efficiency of tension adjustment on the spandex yarn.

[0046] like Figure 2 and Figure 3 As shown, the two movable frames 43 are arranged to form a rhombus. The flexible bend 21 is fixedly sleeved in the middle of the two limiting sleeves 3 so that when the driving structure 44 drives the two limiting sleeves 3 to move closer or further away from each other, the deflection angle of the two rigid tubes 22 can be kept consistent, thereby improving the efficiency of the angle adjustment between the two and improving the accuracy of the angle adjustment.

[0047] like Figure 3As shown, the rigid tube 22 includes a straight tube 221 fixed at one end of the flexible bend tube 21 and an extension tube 222 inserted into one end of the straight tube 221. A threaded sleeve 223 is threadedly installed between the extension tube 222 and the straight tube 221. The threaded sleeve 223 is used to fix the overlapping part of the extension tube 222 and the straight tube 221 after the extension tube 222 is pulled out or pushed in a certain distance in the axial direction. The threads on the outside of the straight tube 221 and the extension tube 222 are in the same direction.

[0048] The threaded sleeve 223 is movably sleeved on the outside of the extension tube 222. The axial length of the thread on the outside of the straight tube 221 is less than the axial length of the threaded sleeve 223, and the axial length of the thread on the outside of the extension tube 222 is greater than the axial length of the threaded sleeve 223. With this design, the total length of the straight tube 221 and the extension tube 222 can be adjusted according to the usage requirements during the conveying of spandex yarn, so that the heat preservation and moisture retention conveying distance of the spandex yarn matches the actual requirements.

[0049] Working principle: When the spandex yarn is static, the drive component 443 drives the threaded rod 441 to rotate, causing it to drive the two sliders 41 to move away from each other vertically. Since the two movable frames 43 form a rhombus shape and their junctions are stacked and hinged on the sliders 41, the two support blocks 432 and the two limiting sleeves 3 are pulled closer together horizontally. This causes the bending point of the flexible bend tube 21 to arch upwards, reducing the angle between the two rigid tubes 22 until the spandex yarn is slightly taut, thus initially adjusting the tension on the spandex yarn. During the conveying of the spandex yarn, under the influence of traction, the tension on the spandex yarn increases. Furthermore, because the spandex yarn contacts the bending point inside the flexible bend tube 21 and generates friction, and the direction of this friction changes, this allows the spandex yarn to... If the tension of the spandex yarn changes irregularly, causing it to bounce, the tension adjustment steps described above can be repeated while the spandex yarn is being conveyed until the bouncing disappears. This improves the stable conveying of the spandex yarn. Before conveying the spandex yarn, the steam generator and its output solenoid valve should be activated in advance to allow steam to be introduced into the guide pipe 2, raising the temperature and humidity inside the guide pipe 2 to an appropriate range. Then, by controlling the opening and closing of the solenoid valve, the temperature and humidity inside the guide pipe 2 can be stabilized within an appropriate range. This provides insulation and moisture retention as the spandex yarn passes through the guide pipe 2, preventing significant temperature and humidity changes during conveying from affecting the quality of the finished product.
