Description

Technical Field

[0001] The present application relates to the field of silk thread processing, and in particular to a processing technology for elastic silk. Background Art

[0002] After the elastic yarn is spun, drawn, twisted and heat-set to obtain the finished product, it needs to be dyed. The elastic yarn needs to be kept soft during the dyeing process, but the elastic yarn is wound into a relatively tight bobbin yarn, which requires a series of operations to transform the bobbin yarn into a bread yarn before dyeing, which is inconvenient.

[0003] In order to process the elastic yarn more conveniently, there is a new processing method for converting the elastic yarn from tube yarn to bread yarn. For example, the publication number CN104097984A is a method for directly forming bread yarn from an elastic yarn tube formed by loose winding. A sock is put on the tube, and the openings at both ends of the sock can be put into the tube. The elastic yarn is twisted and then wound around the sock. After the winding is completed, the two openings of the sock are turned out to wrap the silk thread. The yarn wrapped in the removed sock is the bread yarn.

[0004] Regarding the above-mentioned related technologies, during the process of removing the sock from the sleeve, since the silk threads are tightly wound at this time, there is a large friction between the sock and the sleeve, making it difficult to remove the sock from the sleeve, which affects the processing efficiency of the elastic thread. Summary of the invention

[0005] In order to reduce the impact on the processing efficiency of elastic yarn, the present application provides a processing technology for elastic yarn.

[0006] The present application provides a processing technology for elastic yarn using the following technical solution.

[0007] A processing technology for elastic yarn specifically comprises the following steps.

[0008] Step 1: Put the socks on the sleeve and put the opening of the socks into the sleeve; Step 2, twisting the elastic yarn twice and then winding it on the sock to obtain a bobbin yarn; Step 3: Turn out the openings at both ends of the socks to wrap them around the yarn; Step 4: Reduce the maximum diameter of the sleeve; Step 5: Take the sock out of the sleeve to obtain the bread yarn.

[0009] By adopting the above technical solution, after a sufficient length of elastic thread is wound around the sock, the sleeve is removed from the corresponding rotating shaft. When removing the sock from the sleeve, the diameter of the sleeve is first reduced so that the sock is no longer kept in a tight state, thereby reducing the friction force on the sock when removing the sock, speeding up the removal of the sock and the installation of a new sock, and reducing the impact on the processing efficiency of the elastic thread.

[0010] Optionally, the sleeve includes a central tube, several side rods surrounding the central tube, a fixed sleeve detachably connected to one end of the central tube, a diameter adjusting sleeve movable along the axis of the central tube, a first rod hinged to the side rod and the diameter adjusting sleeve, a second rod hinged to the fixed sleeve, the second rod is slidably connected to the side rod along the axis of the central tube away from one end of the fixed sleeve, the first rod and the second rod are hinged, and the central tube is provided with a diameter adjusting assembly capable of controlling the movement of the diameter adjusting sleeve.

[0011] By adopting the above technical solution, the diameter adjusting sleeve is moved so that the first rod and the second rod connected in a scissor-type manner can rotate accordingly to adjust the distance between the side rod and the center tube, so as to achieve the purpose of adjusting the maximum diameter of the entire sleeve.

[0012] Optionally, the diameter adjustment assembly includes a screw barrel rotatably connected to the center barrel and threadedly connected to the diameter adjustment sleeve, and a rotating barrel member detachably connected to the screw barrel so as to drive the screw barrel to rotate.

[0013] By adopting the above technical solution, the rotation of the rotating drum can cause the screw barrel to rotate accordingly, so that the diameter adjusting sleeve can move accordingly.

[0014] Optionally, both ends of the rotating drum and the fixed sleeve are formed with sealing cavities for the sock opening periphery to be placed in, and a pressing piece is detachably connected to the opening of the sealing cavity to prevent the sock opening periphery from escaping from the sealing cavity.

[0015] By adopting the above technical solution, the sock as a whole is not easily deviated during the process of the elastic thread being wound around the sock, thereby ensuring that the elastic thread is always wound around the sock.

[0016] Optionally, the second rod is rotatably connected to a guide round rod, and the side rod is provided with a guide opening for the guide round rod to slide in a directional manner.

[0017] By adopting the above technical solution, the second rod can stably perform directional movement, and by limiting the movement of the guide round rod, the movement range of the diameter adjusting sleeve is limited, so that the diameter adjusting sleeve is not easy to separate from the screw barrel.

[0018] Optionally, the end of the side rod is formed with a protective arc sheet bent toward one side of the axis of the central tube.

[0019] By adopting the above technical solution, when the sock is detached from the side rod, the presence of the protective arc sheet can prevent the sock from being cut and damaged by the sharp sides or corners of the side rod end, which helps to extend the service life of the sock.

[0020] Optionally, the minimum distance between the protective arc piece and the axis of the central tube is greater than the minimum distance between the corresponding side rod and the central tube.

[0021] By adopting the above technical solution, in the process of putting the new sock on all the side rods, it is necessary to first put one side of the sock on a part of the side rods, that is, the first putting, and then put the other side of the sock on the remaining side rods, that is, the second putting. If the length of the protective arc piece is too long, during the second putting of the sock, the protective arc piece will block the movement of the side edge of the sock opening, which will cause certain obstacles to the smooth putting on of the sock. For this reason, the length of the protective arc piece is limited to facilitate the work of putting the sock on all the side rods accordingly.

[0022] Optionally, the diameter adjusting assembly includes an end sleeve detachably connected to the center tube, an axis shifting ring slidably connected to the end sleeve and detachably connected to the diameter adjusting sleeve, a spring ring detachably connected to the end sleeve, a compression spring located between the spring ring and the axis shifting ring and forcing the axis shifting ring to move toward the fixed sleeve, and a pull rod exposed from the end sleeve to drive the axis shifting ring to move.

[0023] By adopting the above technical solution, the diameter adjusting sleeve can be moved by moving the pull rod, and when the side rod is subjected to greater pressure, the compression spring can be compressed, so that the side rod can move adaptively to reduce the possibility of damage to the side rod.

[0024] Optionally, the pull rod is rotatably connected to the shaft shifting ring, and the pull rod is fixedly connected with a limit block which can be penetrated through the spring ring, and the limit block can abut against the surface of the spring ring facing away from the shaft shifting ring.

[0025] By adopting the above technical solution, when the sock needs to be detached from the side rod, the side rod can be kept close to the central tube to facilitate the removal of the sock.

[0026] Optionally, a groove block is fixedly connected to the surface of the spring ring facing away from the shaft shifting ring, and the groove block is provided with a guide groove for the limit block to enter, and one end of the guide groove is opened opposite to the opening of the spring ring for the limit block to pass through.

[0027] By adopting the above technical solution, the pull rod can be rotated when it is pulled to a position where it cannot be moved; after the new sock is re-installed, the pull rod can be loosened when it is rotated back to a position where it cannot be rotated, so as to facilitate the operation of the pull rod and quickly complete the adjustment of the distance between the side rod and the center tube.

[0028] In summary, the present application includes at least the following beneficial effects.

[0029] After a sufficient length of elastic thread is wound around the sock, the sleeve is removed from the corresponding rotating shaft. When removing the sock from the sleeve, the diameter of the sleeve is first reduced so that the sock is no longer kept in a tight state, thereby reducing the friction force on the sock when removing it, speeding up the removal of the sock and the application of a new sock, and reducing the impact on the processing efficiency of the elastic thread.

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The present application embodiment discloses a processing technology of elastic yarn, referring to Figure 1 , specifically including the following steps.

[0034] Step 1: Put the socks on the sleeve and put the opening of the socks into the sleeve; Step 2, twisting the elastic yarn twice and then winding it on the sock to obtain a bobbin yarn; Step 3: Turn out the openings at both ends of the socks to wrap them around the yarn; Step 4: Reduce the maximum diameter of the sleeve; Step 5: Take the sock out of the sleeve to obtain the bread yarn.

[0035] Reference Figure 2The sleeve in the above steps includes a center cylinder 1, which can be sleeved on the rotating shaft of the corresponding two-for-one twisting machine to be driven to rotate, a fixed sleeve 3 is coaxially and tightly inserted at one end of the center cylinder 1, and a diameter adjusting sleeve 4 is coaxially inserted at the center cylinder 1. A first rod 5 is hinged between the diameter adjusting sleeve 4 and the side rod 2 close to the fixed sleeve 3. The fixed sleeve 3 is hinged with a second rod 51 whose center point is hinged to the center point of the first rod 5. The second rod 51 is slidably connected to the side rod 2 along the axial direction of the center cylinder 1 at one end away from the fixed sleeve 3, so that when the diameter adjusting sleeve 4 moves along the axial direction of the center cylinder 1, the distance between the side rod 2 and the center cylinder 1 can change accordingly.

[0036] Reference Figure 2 The center tube 1 is provided with a diameter adjusting component 52 which can control the movement of the diameter adjusting sleeve 4. The diameter adjusting component 52 includes a screw barrel 53 which is coaxially rotatably connected to the end of the center tube 1 away from the fixed sleeve 3. The outer wall of the screw barrel 53 is coaxially threadedly connected to the diameter adjusting sleeve 4. The end of the screw barrel 53 away from the fixed sleeve 3 is coaxially and detachably connected with a rotating cylinder member 54. The periphery of the rotating cylinder member 54 can be in a non-circular shape such as a plum blossom shape or a hexagonal shape, so that the rotating cylinder member 54 can be rotated using a corresponding wrench.

[0037] Reference Figure 2 The surfaces of the rotating cylinder 54 and the fixed sleeve 3 facing away from each other are provided with sealing chambers 55, and the sealing chambers 55 are for the socks to be placed around the opening, and the sealing chambers 55 can be tightly embedded with a pressing sheet 56 to prevent the socks from being separated from the sealing chambers 55 during the rotation of the central cylinder 1. In addition, the second rod 51 is rotatably connected to a guide round rod 57 at one end close to the side rod 2, and the side rod 2 is provided with a guide opening 58 along the axis direction of the central cylinder 1, and the guide round rod 57 is slidably connected in the guide opening 58, so that the movement of the diameter adjustment sleeve 4 is restricted.

[0038] Reference Figure 2 Each side bar 2 has an integrally formed protective arc piece 59 at both ends, and the protective arc piece 59 is bent toward one side of the axis of the center tube 1, so that when the sock is removed from the side bar, the sock is not easily cut by the end of the side bar 2. In addition, the side bar 2 is closer to the center tube 1 than the protective arc piece 59 connected to it, so that when the sock is put on all the side bars 2 in multiple times, the end of the protective arc piece 59 facing the center tube 1 is not easy to contact the sock, so as to reduce the possibility of damage to the sock.

[0039] Reference Figure 3 and Figure 4In other implementations of this embodiment, the diameter adjustment component 52 includes an end sleeve 41 coaxially detachably connected to the end of the center tube 1 away from the fixed sleeve 3, a shaft shift ring 42 is coaxially slidably connected to the inner wall of the circumference of the end sleeve 41, a connection port 49 is opened through the circumferential surface of the end sleeve 41 along its own axial direction, and the connection port 49 is used for detachable connection between the outer wall of the circumference of the shaft shift ring 42 and the inner wall of the circumference of the diameter adjustment sleeve 4, and there is a spring ring 43 detachably connected to the inner wall of the circumference of the end sleeve 41 at the side of the shaft shift ring 42 away from the fixed sleeve 3, and a compression spring 44 is detachably connected between the spring ring 43 and the end surface of the shaft shift ring 42, and the compression spring 44 forces the shaft shift ring 42 to move toward the fixed sleeve 3, so that the side rod 2 tends to be away from the center tube 1. A pull rod 45 is coaxially rotatably connected to the inner wall of the circumference of the shaft shift ring 42, and the pull rod 45 is penetrated by the spring ring 43 and exposed to the end sleeve 41, so as to directly pull the pull rod 45. In addition, the end sleeve 41 is provided with a sealing cavity 55 and a pressing sheet 56 is embedded therein.

[0040] Reference Figure 4 The pull rod 45 is fixedly connected with a limit block 46 which is passed through the axial direction of the end sleeve 41 and is slidably connected to the end face of the spring ring 43. The surface of the spring ring 43 which is away from the shaft shifting ring 42 is fixedly connected with an arc-shaped groove block 47 which is coaxial with the end sleeve 41. A guide groove 48 is coaxially provided on the inner wall of the circumference of the groove block 47. The guide groove 48 passes through the bottom surface of the groove block 47 facing the spring ring 43. One end of the guide groove 48 is directly opposite to the opening of the spring ring 43 for the limit block 46 to pass through. The limit block 46 can enter into the guide groove 48 and slide, so as to facilitate the corresponding pulling and rotating operations of the pull rod 45.

[0041] The implementation principle of the processing technology of an elastic wire in an embodiment of the present application is: when the elastic wire needs to be wound on the sock and the sock needs to be removed from the side rod 2, the diameter adjusting sleeve 4 is first driven away from the fixed sleeve 3 through the diameter adjusting component 52, so that all the side rods 2 move toward the central tube 1, so as to reduce the distance between any two side rods 2 that are farthest apart, so as to reduce the pressure between the sock and the side rod 2, so as to quickly remove the sock from all the side rods 2.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
