Description

Technical Field

[0001] This application relates to the technical field of yarn processing equipment, and in particular to a spandex heater. Background Technology

[0002] Spandex is a material used to make socks. During processing, spandex is knitted using a sock knitting machine to form socks. During the knitting process, the spandex is stretched and bent to achieve the desired result.

[0003] In low-temperature environments, spandex is affected by the low temperature, resulting in a decrease in overall elasticity. When the elasticity of spandex is insufficient, the quality of the knitted socks will not meet the standards, thus affecting the quality of the socks.

[0004] Currently, spandex is heated using a spandex heating tube. This involves passing the spandex through a tube with a higher temperature, and then using the higher temperature inside the tube to heat the spandex. However, because the spandex moves too fast, the heating time inside the tube is short, resulting in a low temperature rise and making it difficult to raise the spandex to the required temperature.

[0005] Therefore, a new technical solution is needed to address the above problems. Summary of the Invention

[0006] In order to enable spandex to be heated stably to the required temperature and to achieve the required elasticity, this application provides a spandex heater.

[0007] This application provides a spandex heater, which adopts the following technical solution: A spandex heater includes a heating base for heating liquid and generating water vapor, a protective cover disposed on the heating base for storing water vapor, and a plurality of placement brackets disposed inside the protective cover for placing yarn bobbins. The heating base includes a base with an upward opening and a heating tube disposed inside the base. The inner cavity of the base is used to hold liquid. The protective cover is disposed above the base and communicates with the inner cavity of the base. The placement brackets are arranged vertically, and the distance between adjacent placement brackets is greater than the height of the yarn bobbin.

[0008] By adopting the above technical solution, the spandex yarn is placed on a support, and then the liquid is heated by a heating base to form water vapor. The water vapor is used to heat the spandex yarn, thereby raising the temperature of the spandex yarn and enabling the elasticity of the spandex yarn to meet the standard.

[0009] Optionally: The placement bracket includes a fixed frame fixed inside the protective cover and a sliding frame slidably disposed on the fixed frame. The sliding frame slides horizontally on the fixed frame, and one end of the sliding frame can extend out of the protective cover. The protective cover has a plurality of pick-up and put-down holes, the lower end of the pick-up and put-down holes is flush with the lower end of the sliding frame, and the protective cover is also provided with a plurality of pick-up and put-down doors for opening and closing the pick-up and put-down holes.

[0010] By adopting the above technical solution, when it is necessary to remove the spandex, the corresponding pick-and-place door can be opened to remove the spandex, making the pick-and-place of spandex more convenient.

[0011] Optionally, the sliding frame is further provided with a sealing assembly for closing the openings at the upper and lower ends of the yarn bobbin. The sealing assembly includes a lower plug disposed on the sliding frame and an upper plug for closing the opening at the upper end of the yarn bobbin. The lower plug is used to be embedded in the lower end of the yarn bobbin and close the lower end of the yarn bobbin.

[0012] By adopting the above technical solution, when the spandex is heated with water vapor, the openings at both ends of the yarn bobbin are sealed by the sealing component, so that water vapor is not easy to enter the yarn bobbin, thus the yarn bobbin is not easily deformed by the water vapor, and the yarn bobbin can be stably wound with spandex.

[0013] Optionally, the sliding frame is further provided with a limiting component that defines the position of the upper blockage. The limiting component includes a plurality of limiting blocks that are slidably disposed within the upper blockage, a limiting elastic element that pushes the limiting blocks to move, and a reset block for pushing the limiting blocks to reset. The limiting blocks are circumferentially disposed on the side wall of the upper blockage and move radially along the upper blockage. The limiting elastic element pushes the limiting blocks to move in a direction away from the upper blockage. The reset block is disposed above the limiting blocks, and one end of the reset block away from the limiting blocks extends to the upper blockage. The limiting blocks abut against the inner wall of the paper tube.

[0014] By adopting the above technical solution, when the temperature inside the yarn tube rises and causes the internal air pressure to expand, the relative position of the upper plug and the yarn tube can be limited, so that the upper plug can stably seal the upper opening of the yarn tube, thereby making it difficult for water vapor to enter the yarn tube.

[0015] Optionally, the sliding frame is further provided with a connecting assembly for connecting the upper plug to the sliding frame. The connecting assembly includes a fixed rod disposed on the sliding frame, a movable rod rotatably connected to the fixed rod, and a connecting elastic element that pushes the movable rod to rotate upward. The end of the movable rod away from the fixed rod is connected to the upper plug.

[0016] By adopting the above technical solution, the upper plug is connected to the sliding frame. After the upper plug is removed from the yarn bobbin, it can still be connected to the sliding frame, making it less likely for the upper plug to be lost.

[0017] Optionally, the protective cover is provided with a pusher that pushes the movable rod to rotate toward the paper tube. The pusher can abut against the upper end of the movable rod to push the movable rod to rotate until the upper plug is inserted into the paper tube.

[0018] By adopting the above technical solution, the moving rod is pushed towards the yarn tube by the pushing component, so that the upper plug can be stably inserted into the yarn tube. When the upper plug is not inserted into the yarn tube, it can also prevent the sliding frame from moving towards the protective cover, thus providing a reminder.

[0019] Optionally: The fixed frame is provided with a sealing assembly that closes the horizontal section of the inner cavity of the protective cover. The sealing assembly includes several rotating plates rotatably connected to the lower end of the fixed frame and several belts that connect adjacent rotating plates and rotate synchronously. The rotation axis of the rotating plates is horizontally set and perpendicular to the sliding direction of the sliding frame. When adjacent rotating plates rotate to the horizontal state, they abut against each other.

[0020] By adopting the above technical solution, when removing spandex, the rotating plate can be rotated to a near-horizontal state, thereby partially sealing the steam passage near the open pick-up and drop-off port inside the protective cover, reducing the amount of steam emitted to the outside through the pick-up and drop-off port.

[0021] Optionally: A first driven block is provided on both the upper and lower sides of the rotating plate near the end of the sliding frame away from the pick-up and put-down hole. Both first driven blocks are arranged parallel to the rotating plate. A second driven block is also provided on the rotating plate perpendicular to the first driven blocks. An active block is provided below and above the sliding frame. The active block abuts against the first driven block to drive the rotating plate to rotate to a horizontal state. The active block abuts against the second driven block to drive the rotating plate to rotate to a vertical state.

[0022] By adopting the above technical solution, the rotating plate can be automatically driven to move when the sliding frame moves, making the rotation of the rotating plate more convenient.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Place the spandex yarn on the support, then heat the liquid through the heating base to form water vapor. Use the water vapor to heat the spandex yarn, thereby raising the temperature of the spandex yarn and enabling the elasticity of the spandex yarn to reach the standard. 2. When removing spandex, the rotating plate can be rotated to a near-horizontal state, thereby partially sealing the steam passage near the open pick-up / drop-off port inside the protective cover, reducing the amount of steam emitted to the outside through the pick-up / drop-off port.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a spandex heater, such as Figure 1 and Figure 2 As shown, the device includes a heating base 1 for heating liquid and generating steam, a protective cover 2 mounted on the heating base 1 for storing steam, and several placement supports 3 inside the protective cover 2 for placing yarn bobbins. The heating base 1 includes a base 11 with an upward opening and a heating tube 12 disposed within the cavity of the base 11. The heating tube 12 is connected to an external power outlet via an electrical wire, and heats the liquid inside the base 11 to generate steam. The protective cover 2 is cylindrical, with an open lower end face. The protective cover 2 is coaxially mounted on the upper end of the base 11, and the protective cover 2 and the base 11 are sealed together. Several rectangular, rectangular, rectangular holes 21 are provided on the outer wall of the protective cover 2, arranged along the length of the protective cover 2. The outer wall of the protective cover 2 is rotatably connected to a retrieval door 22 that can close the retrieval hole 21. The rotation axis of the retrieval door 22 is vertically arranged. A magnetic suction element is provided at one end of the retrieval door 22 away from its rotation axis. A vertically arranged magnetic strip is provided on the outer wall of the protective cover 2. The magnetic suction element can be attracted to the magnetic strip, so that the protective door can stably close the retrieval hole 21.

[0028] like Figure 3As shown, the placement brackets 3 are arranged along the height direction of the protective cover 2, and the spacing between the placement brackets 3 is greater than the height of the yarn bobbin. The placement brackets 3 include a fixed frame 31 installed inside the cavity of the protective cover 2 and a sliding frame 32 slidably mounted on the fixed frame 31. Both the fixed frame 31 and the sliding frame 32 are frame structures, so that the fixed frame 31 and the sliding frame 32 will not obstruct the movement of water vapor. A handle 33 is provided at the end of the sliding frame 32 near the pick-up and put-down hole 21, so that one end of the sliding frame 32 can be pulled out of the protective cover 2 by applying force to the handle 33. The lower end face of the sliding frame 32 is flush with the lower end face of the pick-up and put-down hole 21, and the upper end face of the pick-up and put-down hole 21 is lower than the lower end face of the fixed frame 31. The spandex that needs to be processed can be wound on the yarn bobbin and placed on the sliding frame 32. Then the sliding frame 32 moves toward the protective cover 2 to let the spandex enter the protective cover 2. After being heated by water vapor, the overall temperature of the spandex rises, so that the elasticity of the spandex can reach the standard.

[0029] Since the outer wall of the yarn bobbin used for winding spandex is usually covered with a thin film, while the inner wall of the yarn bobbin is made of paper, the inner wall of the yarn bobbin will absorb water after prolonged heating with steam, resulting in a decrease in the strength of the yarn bobbin and affecting the winding of the spandex yarn. Therefore, the sliding frame 32 is also provided with a sealing assembly 4 to seal the upper and lower end faces of the yarn bobbin. The sealing assembly 4 includes a lower plug 41 installed on the sliding frame 32 and an upper plug 42 for sealing the upper opening of the yarn bobbin. The lower plug 41 is convex, and its upper end is embedded in the lower opening of the yarn bobbin and fits against the yarn bobbin. A sealing ring is also coaxially provided on the lower plug 41, and the sealing ring abuts against the inner wall of the yarn bobbin. The upper plug 42 is convex downward, and a sealing ring is also coaxially provided at its lower end. The lower end of the upper plug 42 is embedded in the upper opening of the yarn bobbin, and the sealing ring fits against the inner wall of the upper opening of the yarn bobbin. The upper plug 42 and the lower plug 41 respectively seal the openings at the upper and lower ends of the yarn tube, so that water vapor is not easily allowed to enter the inner cavity of the yarn tube, and the strength of the yarn tube is not easily affected by water vapor.

[0030] like Figure 4As shown, the upper plug 42 is also provided with a limiting component 5 that limits the position of the upper plug 42. The limiting component 5 includes two limiting blocks 51 that are slidably disposed in the upper plug 42, a limiting elastic member 53 that pushes the two limiting blocks 51 away from each other, and two reset blocks 52 for pushing the limiting blocks 51 to reset. The two reset blocks 52 are disposed at the ends of the limiting blocks 51 that are close to each other, so that the limiting blocks 51 and the reset blocks 52 are arranged in an L-shape. A sliding groove 421 is opened on the upper end surface of the upper plug 42. Limiting grooves 422 are respectively opened on the side walls of the sliding groove 421 that are far apart from each other. The limiting grooves 422 penetrate the two side walls of the upper plug 42 located below. The limiting blocks 51 are disposed in the limiting grooves 422 and can slide in the limiting grooves 422 and can extend out of the limiting grooves 422 to abut against the inner wall of the yarn tube. Two reset blocks 52 are slidably disposed within the sliding groove 421, with the upper end of each reset block 52 extending out of the sliding groove 421. In this embodiment, a spring is used as the limiting elastic element 53. The limiting elastic element 53 is disposed within the sliding groove 421, with one end abutting against the side wall of the reset block 52 away from the limiting block 51, and the other end fixed to the inner wall of the sliding groove 421. A cover plate 423 is also installed on the upper surface of the upper plug 42, positioned between the two reset blocks 52. The cover plate 423 partially covers the upper surface of the sliding groove 421, and when the limiting block 51 is fully retracted into the limiting groove 422, the cover plate 423 abuts against the reset block 52. The limiting component 5 enables the upper plug 42 to stably close the upper opening of the yarn bobbin. Even when the internal temperature of the yarn bobbin increases, causing a change in air pressure, the upper plug 42 can still stably close the upper end of the yarn bobbin.

[0031] like Figure 3 As shown, since the upper plug 42 needs to be removed when removing the yarn bobbin, and it is easy to misplace it after removal, making it impossible to find, the sliding frame 32 is also provided with a connecting assembly 6 that connects the upper plug 42 to the sliding frame 32. The connecting assembly 6 includes a fixed rod 61 disposed on the sliding frame 32, a movable rod 62 rotatably connected to the fixed rod 61, and a connecting elastic element 63 that pushes the movable rod 62 to rotate upward. The fixed rod 61 is disposed at the end of the sliding frame 32 away from the loading and unloading port, and the upper end surface of the fixed rod 61 is higher than the upper end surface of the yarn bobbin. One end of the movable rod 62 is connected to the upper end of the fixed rod 61, and the other end of the movable rod 62 is fixed to the upper plug 42. In this embodiment, the connecting elastic element 63 is a torsion spring, and the connecting elastic element 63 is disposed at the rotatable connection between the fixed rod 61 and the movable rod 62. After the sliding frame 32 is dragged outward toward the protective cover 2, the movable rod 62 can rotate upward under the push of the connecting elastic element 63, so that the upper plug 42 is disengaged from the yarn tube, making the picking and putting of the yarn tube less affected, and also limiting the position of the upper plug 42.

[0032] Inside the protective cover 2, there is also a pusher 64 that pushes the movable rod 62 toward the yarn bobbin. The pusher 64 is located on the inner wall of the protective cover 2. The end of the pusher 64 away from the protective cover 2 is provided with an abutment block. The abutment block can abut against the upper end of the movable rod 62, thereby driving the movable rod 62 to move downward. After the sliding frame 32 is pushed into the protective cover 2, the upper plug 42 can close the upper opening of the yarn bobbin. If the upper plug 42 fails to close, the sliding frame 32 cannot be fully pushed into the protective cover 2, thus providing a reminder.

[0033] like Figure 3 As shown, after the loading / unloading door 22 is opened, a large amount of water vapor will be discharged from the protective cover 2, which means that it will take a certain amount of time for the protective cover 2 to be refilled with water vapor, affecting the heating of the spandex by the water vapor. Therefore, a sealing assembly 7 is also provided below the fixing frame 31 to close the horizontal section of the inner cavity of the protective cover 2. The sealing assembly 7 includes several rotating plates 71 rotatably connected to the lower end of the fixing frame 31 and several belts 72 that connect adjacent rotating plates 71 and drive them synchronously. A damping ring is provided between the rotating plates 71 and the fixing frame 31. The rotating plates 71 are arranged along the moving direction of the sliding frame 32, and the rotation axis of the rotating plates 71 is horizontal and perpendicular to the sliding direction of the sliding frame 32. When the rotating plates 71 rotate to a near-horizontal state, the adjacent rotating plates 71 can remain in contact, thereby reducing the area of ​​the passage for steam to pass through the protective cover 2 and reducing steam loss. The belts 72 are provided on the adjacent rotating plates 71, so that the rotating plates 71 can rotate synchronously.

[0034] like Figure 2 and Figure 5 As shown, two first driven blocks 73 are also provided on the rotation shaft of the rotating plate 71 near the end of the sliding frame 32 away from the pick-up and put-down hole 21. The first driven blocks 73 are respectively provided on the upper and lower sides of the rotation shaft of the rotating plate 71, and the two first driven blocks 73 on the same rotating plate 71 are both parallel to the rotating plate 71. A second driven block 76 is also provided on the rotating plate 71. The second driven block 76 is provided between the two first driven blocks 73 and perpendicular to the first driven blocks 73. An active block 74 is provided below and above the sliding frame 32. The active block 74 can abut against the first driven block 73 and the second driven block 76 to drive the rotating plate 71 to rotate automatically. When the sliding frame 32 moves outward from the protective cover 2, the active block 74 abuts against the first driven block 73 to drive the rotating plate 71 to rotate and make the adjacent rotating plates 71 abut against each other. When the sliding frame 32 has moved completely into the protective cover 2, the active block 74 abuts against the second driven block 76 to drive the rotating plate 71 to rotate to a vertical position. After the sliding frame 32 has moved completely into the protective cover 2, the active block 74 is disengaged from the first driven block 73 and the second driven block 76.

[0035] The implementation principle of this embodiment is as follows: Open the pick-up and put-out door 22, pull the sliding frame 32 out from the protective cover 2. During the process of pulling out the sliding frame 32, the sliding frame 32 drives the rotating plate 71 to rotate, so that the adjacent rotating plates 71 abut against each other, thereby hindering the movement of water vapor. Then, place the yarn bobbin on the lower plug 41, press the upper plug 42 into the upper opening of the yarn bobbin, and then push the sliding frame 32 into the protective cover 2 and close the pick-up and put-out door 22.

[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
