Description

Technical Field

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

[0002] Spandex is a material used to make socks. During the processing, the spandex needs to be woven through a sock knitting machine to form socks. During the weaving process, the spandex will be stretched and bent as a whole to form the desired result.

[0003] In a low temperature environment, spandex will be affected by the low temperature and its overall elasticity will be reduced. 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 by a spandex heating tube, that is, the spandex passes through a tube with a higher temperature, and the higher temperature in the heating tube is used to heat the spandex passing through. However, since the spandex moves too fast, the heating time in the heating tube is short, the temperature rise of the spandex is low, and it is difficult to raise the spandex to the required temperature.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the invention

[0008] By adopting the above technical solution, the spandex yarn is placed on a placement bracket, and then the liquid is heated by a heating base to form water vapor, and the water vapor is used to heat the spandex yarn, so that the temperature of the spandex yarn rises and the elasticity of the spandex yarn can reach the standard.

[0009] Optional: The placement bracket includes a fixed frame fixed in the protective cover and a sliding frame slidably arranged on the fixed frame, the sliding frame slides horizontally on the fixed frame, one end of the sliding frame can extend out of the protective cover, a plurality of picking and releasing holes are opened on the protective cover, the lower ends of the picking and releasing holes are flush with the lower end of the sliding frame, and the protective cover is also provided with a plurality of picking and releasing doors for opening and closing the picking and releasing holes.

[0012] By adopting the above technical solution, when the spandex is heated by water vapor, the openings at the upper and lower ends of the yarn tube are sealed by the sealing assembly, so that the water vapor is not easy to enter the yarn tube, and the yarn tube is not easily deformed by the water vapor, so that the yarn tube can stably wind the spandex.

[0013] Optionally: the sliding frame is also provided with a limit assembly for limiting the position of the upper blockage, the limit assembly includes a plurality of limit blocks slidably arranged in the upper blockage, a limit elastic member for pushing the limit blocks to move, and a reset block for pushing the limit blocks to reset, the limit blocks are circumferentially penetrated on the side walls of the upper blockage and move radially along the upper blockage, the limit elastic member pushes the limit blocks to move in the direction away from the upper blockage, the reset block is arranged above the limit block, one end of the reset block away from the limit block extends to above the upper block, and the limit block abuts 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 close the upper end opening of the yarn tube, thereby preventing water vapor from entering the yarn tube.

[0015] Optionally: The sliding frame is also provided with a connecting assembly that connects the upper stopper to the sliding frame, and the connecting assembly includes a fixed rod set on the sliding frame, a movable rod rotatably connected to the fixed rod, and a connecting elastic member that pushes the movable rod to rotate upward, and the end of the movable rod away from the fixed rod is connected to the upper stopper.

DETAILED DESCRIPTION

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] The present application discloses a spandex heater, such as Figure 1 and Figure 2 As shown, it includes a heating seat 1 for heating liquid and generating water vapor, a protective cover 2 arranged on the heating seat 1 for storing water vapor, and a plurality of placement brackets 3 arranged in the protective cover 2 for placing yarn tubes. The heating seat 1 includes a base 11 with an upper opening, and a heating tube 12 arranged in the inner cavity of the base 11. The heating tube 12 is connected to an external power socket through an electric wire. The heating tube 12 is used to heat the liquid in the base 11 to generate water vapor. The protective cover 2 is arranged in a cylindrical shape, and the lower end surface of the protective cover 2 is arranged in an open manner. 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. A plurality of access holes 21 connected to its inner cavity are provided on the outer wall of the protective cover 2. The access holes 21 are arranged in a rectangular shape and arranged along the length direction of the protective cover 2. A pick-and-place door 22 capable of closing the pick-and-place hole 21 is rotatably connected to the outer wall of the protective cover 2. The rotation axis of the pick-and-place door 22 is vertically arranged. A magnetic attraction piece is arranged at one end of the pick-and-place door 22 away from its rotation axis. A vertically arranged magnetic attraction strip is arranged on the outer wall of the protective cover 2. The magnetic attraction piece can be attracted to the magnetic attraction strip, so that the protective door can stably close the pick-and-place hole 21.

[0028] like Figure 3As shown, the placement bracket 3 is arranged along the height direction of the protective cover 2 and the spacing of the placement bracket 3 is greater than the height of the yarn tube. The placement bracket 3 includes a fixed frame 31 installed in the inner cavity of the protective cover 2 and a sliding frame 32 slidably arranged on the fixed frame 31. The fixed frame 31 and the sliding frame 32 are both frame structures, so that the fixed frame 31 and the sliding frame 32 will not hinder the movement of water vapor. A handle 33 is provided at one end of the sliding frame 32 close to the access 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 surface of the sliding frame 32 is flush with the lower end surface of the access hole 21, and the upper end surface of the access hole 21 is set lower than the lower end surface of the fixed frame 31. The spandex to be processed can be wound on the yarn tube and placed on the sliding frame 32, and then the sliding frame 32 moves toward the protective cover 2 to allow the spandex to enter the protective cover 2. After being heated by water vapor, the overall spandex temperature is increased, so that the elasticity of the spandex can reach the standard.

[0029] Since the outer wall of the yarn drum used for winding spandex is usually covered with a film, and the inner wall of the yarn drum is made of paper, after being heated by steam for a long time, the inner wall of the yarn drum will absorb water, resulting in a decrease in the strength of the yarn drum, which affects the winding of the spandex yarn. Therefore, the sliding frame 32 is also provided with a plugging assembly 4 for sealing the upper and lower end faces of the yarn drum, and the plugging assembly 4 includes a lower plug 41 installed on the sliding frame 32 and an upper plug 42 for plugging the upper end opening of the yarn drum. The lower plug 41 is convexly arranged, and the upper end of the lower plug 41 is embedded in the lower end opening of the yarn drum and fits with the yarn drum. The lower plug 41 is also coaxially provided with a sealing ring, and the sealing ring abuts against the inner wall of the yarn drum. The upper plug 42 is convexly arranged, and the lower end of the upper plug 42 is also coaxially provided with a sealing ring, and the lower end of the upper plug 42 is embedded in the upper end opening of the yarn drum, and the sealing ring fits with the inner wall of the upper end opening of the yarn drum. 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 easy 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 limit assembly 5 for limiting the position of the upper plug 42, and the limit assembly 5 includes two limit blocks 51 slidably arranged in the upper plug 42, a limit elastic member 53 for pushing the two limit blocks 51 away from each other, and two reset blocks 52 for pushing the limit blocks 51 to reset, and the two reset blocks 52 are arranged at one end of the limit blocks 51 close to each other, so that the limit blocks 51 and the reset blocks 52 are arranged in an L shape. A sliding groove 421 is provided on the upper end surface of the upper plug 42, and the side walls of the sliding groove 421 away from each other are respectively provided with limit grooves 422, and the limit grooves 422 penetrate the two side walls of the upper plug 42 located below, and the limit block 51 is arranged in the limit groove 422 to slide and can extend out of the limit groove 422 to abut against the inner wall of the yarn tube. Two reset blocks 52 are arranged to slide in the sliding groove 421, and the upper end of the reset block 52 extends out of the sliding groove 421. The limiting elastic member 53 is a spring in this embodiment. The limiting elastic member 53 is arranged in the sliding groove 421. One end of the limiting elastic member 53 abuts against the side wall of the reset block 52 away from the limiting block 51, and the other end of the limiting elastic member 53 is fixed to the inner wall of the sliding groove 421. A cover plate 423 is also installed on the upper end surface of the upper plug 42. The cover plate 423 is arranged between the two reset blocks 52. The cover plate 423 partially covers the upper end surface of the sliding groove 421, and when the limiting block 51 is completely retracted into the limiting groove 422, the cover plate 423 can abut against the reset block 52. The limiting assembly 5 is used to enable the upper plug 42 to stably close the upper end opening of the yarn drum. When the temperature inside the yarn drum increases and the air pressure changes, the upper plug 42 can still stably close the upper end of the yarn drum.

[0031] like Figure 3 As shown, since the upper plug 42 needs to be removed when the bobbin is removed, and after removal, it is easy to be placed randomly so that the upper plug 42 cannot be found, a connecting assembly 6 for connecting the upper plug 42 with the bobbin is also provided on the sliding frame 32, and the connecting assembly 6 includes a fixed rod 61 provided on the sliding frame 32, a movable rod 62 rotatably connected to the fixed rod 61, and a connecting elastic member 63 for pushing the movable rod 62 to rotate upward. The fixed rod 61 is provided at one end of the sliding frame 32 away from the access port, and the upper end surface of the fixed rod 61 is higher than the upper end surface of the 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 member 63 uses a torsion spring, and the connecting elastic member 63 is provided at the rotation connection between the fixed rod 61 and the movable rod 62. After the sliding frame 32 is dragged toward the outside of the protective cover 2, the movable rod 62 can rotate upward under the push of the connecting elastic member 63, so that the upper plug 42 is disconnected from the yarn tube, making the placement of the yarn tube less susceptible to influence, and also limiting the position of the upper plug 42.

[0032] A pushing member 64 is also provided in the protective cover 2 to push the movable rod 62 to move toward the yarn tube. The pushing member 64 is provided on the inner wall of the protective cover 2. An abutment block is provided at the end of the pushing member 64 away from the protective cover 2. The abutment block can abut against the upper end of the movable rod 62 to drive the movable rod 62 to move downward, so that after the sliding frame 32 is pushed into the protective cover 2, the upper plug 42 can close the upper end opening of the yarn tube, and when the upper plug 42 fails to close the upper plug 42, the sliding frame 32 cannot be completely pushed into the protective cover 2, thereby giving a reminder.

[0033] like Figure 3 As shown, after the access door 22 is opened, a large amount of water vapor in the protective cover 2 will be discharged, so that it takes a certain amount of time for the protective cover 2 to be filled with water vapor again, which affects the heating of the spandex by the water vapor. Therefore, a closing component 7 with a partially closed horizontal cross-section of the inner cavity of the protective cover 2 is also provided below the fixed frame 31. The closing component 7 includes a plurality of rotating plates 71 rotatably connected to the lower end of the fixed frame 31 and a plurality of belts 72 that connect and synchronously drive the adjacent rotating plates 71. A damping ring is provided between the rotating plates 71 and the fixed frame 31. The rotating plates 71 are arranged along the moving direction of the sliding frame 32, and the rotating axis of the rotating plates 71 is horizontally arranged and perpendicular to the sliding direction of the sliding frame 32. When the rotating plates 71 rotate to a state close to the horizontal state, the adjacent rotating plates 71 can maintain contact with each other, thereby reducing the area of ​​the passage for passing steam in the protective cover 2 and reducing the loss of steam. 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 follower blocks 73 are further arranged on the rotating shaft of the rotating plate 71 close to the end of the sliding frame 32 away from the access hole 21. The first follower blocks 73 are respectively arranged on the upper and lower sides of the rotating shaft of the rotating plate 71. The two first follower blocks 73 on the same rotating plate 71 are both arranged parallel to the rotating plate 71. The rotating plate 71 is also provided with a second follower block 76, which is arranged between the two first follower blocks 73 and perpendicular to the first follower blocks 73. Active blocks 74 are 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 toward the outside of 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. When the sliding frame 32 is completely moved 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 state. After the sliding frame 32 is completely moved into the protective cover 2, the active block 74 is disconnected from the first driven block 73 and the second driven block 76.

[0035] The implementation principle of this embodiment is: open the access door 22, pull the sliding frame 32 out of the protective cover 2, and in the process of pulling out the sliding frame 32, the sliding frame 32 drives the rotating plate 71 to rotate, so that adjacent rotating plates 71 abut against each other to hinder the movement of water vapor, and then place the yarn tube on the lower plug 41, press the upper plug 42 into the upper end opening of the yarn tube, and then push the sliding frame 32 into the protective cover 2 and close the access door 22.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
