Description

Technical Field

[0001] This invention relates to the field of core-spun yarn preparation technology, specifically to an integrated conductive drying and curing device and processing method for preparing spandex core-spun yarn. Background Technology

[0002] During the preparation of spandex core-spun yarn, residual moisture on the surface of the yarn during the dyeing process, if not treated, affects the subsequent twisting process. Existing spandex core-spun yarn drying equipment dries the yarn in piles or strands, making it difficult for the inner spandex core-spun yarn to dry completely, resulting in low drying efficiency. Furthermore, the equipment cannot achieve a continuous drying process, and the polarized drying process has significant limitations in its use.

[0003] The invention disclosed in CN116465178A is a multi-channel conductive drying device and preparation process for preparing spandex core-spun yarn, including a base plate and a folding frame fixedly connected to the top of the base plate, wherein a transverse metal tube is fixedly connected to the inner surface of the folding frame.

[0004] As shown in the invention above, existing drying equipment for preparing spandex core-spun yarn generally uses a spreading device on the left side of a triangular support frame. The yarn passes horizontally through the spreading device into a metal pipe and then exits horizontally from the transverse metal pipe. This ensures that the spandex core-spun yarn is in a horizontal state when it enters the metal pipe, ensuring uniform heating. In addition, it is designed with multi-channel conductive drying. Although this method spreads the yarn and ensures that it is in a horizontal state through the spreading device, it cannot guarantee that the yarn is in a horizontal state when the yarn tension decreases or the yarn becomes loose due to other reasons. This affects the drying and curing effect of the yarn and cannot meet the production efficiency of spandex core-spun yarn. Summary of the Invention

[0025] Beneficial effects

[0026] This invention provides an integrated conductive drying and curing device and method for preparing spandex core-spun yarn. Compared with the prior art, it has the following advantages:

[0027] 1. The integrated conductive drying and curing equipment and method for preparing spandex core-spun yarn has multiple drying and curing components on the connecting frame, which can simultaneously dry and cure multiple strands of spandex core-spun yarn. The connecting frame is connected to the drying and curing components through an adjustment unit, and a control component is set at the outlet of the drying and curing components.

A second movable rod 62 is movably connected to the middle of the first movable rod 61 via a slot and a pin. One end of the second movable rod 62 is movably connected to a protrusion 84 on the other side of the second annular plate 52 via a pin. The first movable rod 61 and the second movable rod 62 cooperate to form a "V"-shaped structure. The second movable rod 62 is moved and rotated by a telescopic cylinder 22. The second movable rod 62 and the first movable rod 61 cooperate to lift the drying and curing assembly 4. The middle parts of the first movable rod 61 and the second movable rod 62 are connected by a stabilizing assembly 7. The other end of the first movable rod 61 is movably connected to an arc-shaped connecting plate 63 via a pin. A bushing 64 is sleeved on the inner side of the arc-shaped connecting plate 63.

The bushing 64 on the other adjusting component 6 is movably sleeved on the other end of the curing cylinder 43 via a bearing. Multiple guide plates 65 with equal spacing and arc-shaped distribution are fixed on the inner wall of the arc-shaped connecting plate 63. Multiple guide grooves 66 adapted to the guide plates 65 are opened on the outer wall of the bushing 64. The guide plates 65 and guide grooves 66 cooperate to limit the movement, so that the arc-shaped connecting plate 63 keeps moving horizontally and does not rotate relative to the bushing 64. Multiple balls are provided at the connection between the guide plates 65 and the guide grooves 66 to reduce the friction between the guide plates 65 and the guide grooves 66, so that the arc-shaped connecting plate 63 and the bushing 64 can move easily. An extension plate 67 is fixed to the bottom of one end of the bushing 64. A guide wheel 68 is movably connected to the extension plate 67 via a pin. The guide wheel 68 plays the role of guiding the yarn.

[0047] The stabilizing component 7 includes stabilizing rods 71 ​​disposed on both sides of the middle portion of the first movable rod 61. One end of the stabilizing rod 71 is movably connected to the first movable rod 61 via a pin, and the other end of the stabilizing rod 71 is movably connected to a bonding plate 72 via a pin. The bonding plate 72 is bonded to the outer middle portion of the second movable rod 62. The stabilizing rod 71, together with the first movable rod 61 and the second movable rod 62, forms a triangular stabilizing structure, improving the stability of the adjusting unit 3. A dovetail slider 73 is fixed to the inner middle portion of the bonding plate 72, and a micro motor 74 is fixed to one outer end of the bonding plate 72. A groove 75 is formed at the bottom end of the dovetail slider 73, and a toothed block 76 is disposed within the groove 75. The micro motor 74... The output shaft passes through the bonding plate 72 and is connected to the screw hole on the toothed block 76. Dovetail grooves 77 are provided on both sides of the middle part of the second movable rod 62. The bottom of the dovetail groove 77 is provided with a toothed groove 78. The dovetail groove 77 is adapted to the dovetail slider 73 to limit the bonding plate 72 on the second movable rod 62, while allowing the bonding plate 72 to move. The toothed groove 78 is adapted to the toothed block 76 to limit the bonding plate 72 and the second movable rod 62, thereby limiting the stabilizing rod 71 and the second movable rod 62. The stabilizing rod 71, together with the first movable rod 61 and the second movable rod 62, forms a triangular stable support structure, so that the adjustment unit 3 plays a stable support role when it is not working.

[0048] The drying and curing assembly 4 is located on the outside of the connecting frame 2. Both ends of the drying and curing assembly 4 are connected to the adjusting unit 3, and the middle part of the drying and curing assembly 4 is connected to the connecting frame 2 via a telescopic rod 21. It is used to dry and cure the core-spun yarn. The drying and curing assembly 4 includes a water-absorbing cylinder 41, a drying cylinder 42, and a curing cylinder 43. A first annular tooth 411 is fixed to the outer side of one end of the water-absorbing cylinder 41. Multiple semi-circular sponge blocks 412 are embedded on both sides of the inside of the water-absorbing cylinder 41 in an equally spaced and staggered manner. The semi-circular sponge blocks 412 are located on the inner walls of both sides of the water-absorbing cylinder 41. The curved magnetic plate is magnetically attached to the inner wall of the water-absorbing cylinder 41. After the device has finished working, the curved magnetic plate can be removed to clean the semi-circular sponge blocks 412 on it. Multiple semi-circular sponge blocks 412 work together to absorb the residual moisture adhering to the surface of the spandex core-spun yarn. The other end of the water-absorbing cylinder 41 is connected to one of the adjusting units 3. Fans 421 are fixed in the middle of the upper and lower sides of the drying cylinder 42. The lower fan 421 is a hot air fan 421, and the upper fan 421 is an exhaust fan 421. The cooperation of the blower 421 forms a flow channel within the inner cavity of the drying cylinder 42, facilitating the drying of the spandex core-spun yarn. Gearboxes 423 are fixed at both ends of the drying cylinder 42, with a reduction motor 422 connected to the input end of each gearbox 423. Multiple arc-shaped air guide plates 424 arranged in a circular array are fixed on the inner wall of the drying cylinder 42. These arc-shaped air guide plates 424 cooperate to form a spiral air channel, improving the drying effect of the drying cylinder 42. A second annular tooth 431 is fixed to the outer side of one end of the curing cylinder 43. Both the second annular tooth 431 and the first annular tooth 411 interact with the gears. The output end of the box 423 is connected, and two geared motors 422 drive the water suction cylinder 41 and the curing cylinder 43 to rotate through the gear box 423 and two ring gears respectively, which improves the working efficiency of the water suction cylinder 41 and the curing cylinder 43. A tempered glass tube is embedded in the middle of the curing cylinder 43, and a curing lamp box 432 is sleeved on the outside of the tempered glass tube. The curing lamp in the curing lamp box 432 heats and cures the spandex core-spun yarn inside the tempered glass tube at high temperature. The other end of the curing cylinder is connected to another adjustment unit 3, and a control component 8 is provided on the other adjustment unit 3.

[0049] Control component 8 is mounted on adjustment component 6 and is used to control adjustment unit 3 to adjust the opening degree, so that the core-spun yarn remains taut during drying and curing. Control component 8 includes mounting bracket 81 fixed on another extension plate 67. A micro switch 82 is fixed to the end of mounting bracket 81. Micro switch 82 is electrically connected to telescopic cylinder 22. A contact plate 83 is provided at the output end of micro switch 82. A protrusion 84 is fixed to one side of the end of mounting bracket 81. A movable rod 85 is inserted into the slot on the protrusion 84. One end of movable rod 85 is connected to the bottom of the slot through a second spring. A movable sleeve 8 is fixed to the other end of movable rod 85. 6. The movable sleeve 86 is located outside the contact plate 83 and in the middle of the opening of the curing cylinder 43. The spandex core-spun yarn passes through the movable sleeve 86 at the outlet of the curing cylinder 43. When the spandex core-spun yarn is taut, it drives the movable sleeve 86 to move outward, separating the movable sleeve 86 from the contact plate 83. When the spandex core-spun yarn is loose, the movable sleeve 86 returns under the action of the second spring. At this time, the movable sleeve 86 contacts the contact plate 83, activating the micro switch 82, which controls the telescopic cylinder 22 to start. The adjusting unit 3 controls the movement of the drying and curing assembly 4 to taut the spandex core-spun yarn again.

[0050] The second embodiment differs from the first embodiment in that: the present invention also discloses a conductive drying and curing treatment method for preparing spandex core-spun yarn, comprising the following steps:

[0051] Step 1: First, the dyed spandex core-spun yarn is divided into multiple strands, and each strand is connected to the guide wheel 68 on one of the adjustment units 3. Then, it passes through the water absorption cylinder 41, the drying cylinder 42 and the curing cylinder 43 in sequence. Next, it passes through the movable sleeve 86 at the opening of the curing cylinder 43 and is connected to the guide wheel 68 on another adjustment unit 3. Finally, it is wound up by an external winding mechanism.

[0052] Step Two: Before operation, the controller 11 activates multiple synchronized telescopic cylinders 22. The telescopic cylinders 22 move the first annular plate 51 on the buffer assembly 5. The first annular plate 51, via the first spring 56, moves the second annular plate 52. The second annular plate 52 simultaneously moves and rotates multiple second movable rods 62. The second movable rods 62, in conjunction with the first movable rods 61, lift the drying and curing assembly 4, causing multiple drying and curing assemblies 4 to move outwards simultaneously. During this process, the arc-shaped connecting plate 63 connected to the first movable rod 61 and the bushing 64 experience relative displacement. The arc-shaped connecting plate 63, under the action of the guide plate 65 and the guide groove 66, moves horizontally. The ball bearings on the guide plate 65 reduce the friction between the arc-shaped connecting plate 63 and the bushing 64, making the arc-shaped connecting plate 63 easier to move. This ensures that the fixed length of the first movable rod 61 does not affect the movement of the drying and curing component 4. At the same time, the telescopic rod 21 between the connecting frame 2 and the drying and curing component 4 is stretched. The telescopic rod 21 plays a guiding role, allowing the drying and curing component 4 to maintain linear movement. When the first movable rod 61 and the second movable rod 62 deflect each other, the two bonding plates 72 move on the second movable rod 62 through the dovetail slider 73 and the dovetail groove 77, causing the two stabilizing rods 71 ​​to deflect until the spandex core-spun yarn is in a taut state.

[0053] Step 3: When the spandex core-spun yarn is in a taut state, the spandex core-spun yarn drives the movable sleeve 86 to move away from the contact plate 83 until the movable sleeve 86 separates from the contact plate 83. At this time, the micro switch 82 is activated in reverse to control the telescopic cylinder 22 to stop driving and prevent the spandex core-spun yarn from breaking.

[0054] Step 4: When this device is working, firstly, the multiple staggered sponge blocks 412 inside the water absorption cylinder 41 can absorb the residual moisture on the spandex core-spun yarn. Then, the controller 11 controls the two fans 421 inside the drying cylinder 42 to start. The two fans 421 work with the air guide plate 424 inside the drying cylinder 42 to dry the spandex core-spun yarn. Next, the curing light box 432 outside the curing cylinder 43 uses the curing lamp inside to perform high-temperature curing treatment on the spandex core-spun yarn inside the curing cylinder 43.

[0055] During the above-mentioned operation, when the spandex core-spun yarn becomes loose for some reason, the movable sleeve 86 loses its outward expansion force. At this time, the movable sleeve 86 returns to its original position under the action of the second spring until it contacts the contact plate 83, activating the micro switch 82. The micro switch 82 drives the telescopic cylinder 22 to start, and at the same time, the controller 11 controls the micro motor 74 to rotate in the opposite direction, causing the toothed block 76 to separate from the toothed groove 78, releasing the limit of the stabilizing rod 71 and the second movable rod 62. At this time, the telescopic cylinder 22 drives the first annular plate 51 and the second annular plate 52 to move. The second annular plate 52 drives the second movable rod 62 and the first movable rod 61 to rotate, thereby driving the drying... The curing component 4 moves outward, straightening the spandex core-spun yarn again. When the spandex core-spun yarn is straightened again, the movable sleeve 86 moves outward under force until the movable sleeve 86 separates from the contact plate 83, triggering the micro switch 82. This causes the micro switch 82 to control the telescopic cylinder 22 to stop driving. At the same time, the controller 11 controls the micro motor 74 to rotate forward, driving the tooth block 76 to mesh with the tooth groove 78, limiting the bonding plate 72 and the second movable rod 62. This further limits the stabilizing rod 71 and the second movable rod 62, so that the stabilizing rod 71, together with the second movable rod 62 and the first movable rod 61, forms a triangular stable limiting structure, which stably limits the drying and curing component 4, enabling the device to work stably.

[0056] Since both the movable sleeve 86 and the contact plate 83 are mounted on the mounting bracket 81, when the drying and curing assembly 4 moves, it will cause the movable sleeve 86 and the contact plate 83 to move as a whole. The relative positions of the movable sleeve 86 and the contact plate 83 remain unchanged, so the movement of the drying and curing assembly 4 as a whole does not affect the change in the relative positions of the movable sleeve 86 and the contact plate 83.

[0057] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
