Technical Field
[0001] This invention belongs to the field of fancy yarn production control technology, specifically relating to a control device and method for fancy yarn production. Background Technology
[0002] Fancy yarn production involves creating yarns with unique appearances, structures, or properties by using special raw material combinations, modifying spinning equipment, or adjusting processes on top of conventional yarns. These yarns differ from ordinary plain yarns (such as pure cotton or polyester yarns) and feature three-dimensional or irregularly shaped effects such as knots, slubs, loops, ripples, braids, and chenille. They are primarily used for decorating knitted and woven fabrics and are commonly found in sweaters, scarves, blankets, and home textiles.
[0003] A search of patent document CN202311383862.2 discloses a yarn winding device for yarn production, including a base, a yarn feeding mechanism and a yarn winding mechanism mounted on the base. The yarn winding mechanism includes a mounting frame, a storage cylinder, a column, a yarn winding device, a lowering component, a first electric telescopic rod, a magnetic component, a second electric telescopic rod, and a motor. In this invention, the yarn winding device has two forms. In its initial state, the yarn winding device is kept in a conical shape by the action of an elastic ring and a spring. In this state, it is easy to stack the yarn winding devices one on top of the other, saving space and facilitating replacement through mechanical design. When winding, the yarn winding device takes on a columnar shape, and two independent winding areas are formed by a partition around the yarn winding device. Compared with the prior art, this invention can separately wind up the two strands of yarn fed by the yarn feeding mechanism, solving the problems of space occupation and single winding function of the integrated winding cylinder in the prior art.
[0004] The aforementioned patent still has drawbacks in terms of controlling the winding of fancy yarns: when controlling the fancy yarn to achieve uniform winding through reciprocating movement, the lateral distance of the reciprocating movement is constant due to the fixed linear drive method. Therefore, after the fancy yarn is wound, the fancy yarns on both sides will "collapse" due to the lack of obstruction, leading to winding failure. Furthermore, during long-term operation, the fancy yarn will always be in contact with the end of the roller when winding through it, which will cause wear and tear on the fancy yarn over a long period of time. Therefore, in summary, improvements are needed. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the present invention aims to provide a control device and method for fancy yarn production. This effectively solves the problem that most existing technologies use a fixed linear drive method, where the lateral distance of the reciprocating movement is constant. As a result, after the fancy yarn is wound, the yarn on both sides will "collapse" due to the lack of obstruction, leading to winding failure. Furthermore, during long-term operation, the fancy yarn will continuously contact the end of the roller while being wound, causing wear and tear on the yarn over a prolonged period.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a control device for fancy yarn production, comprising a fancy yarn making module, and further comprising: The loop yarn module is located on one side of the fancy yarn making module; The movement control module is fixed to the side of the loop yarn module near the fancy yarn making module; The movement control module includes a positioning component and a stabilization module. The positioning component includes a first plate with a rectangular groove inside. An auxiliary plate component and a press-type delayed automatic reset switch are installed on the first plate. Multiple sets of the auxiliary plate component and the press-type delayed automatic reset switch are arranged in a cross-vertical distribution, with each auxiliary plate component and press-type delayed automatic reset switch forming a group. The stabilization module includes a positioning hollow roller and a filter tube. The filter tube is sleeved inside the positioning hollow roller. Arc-shaped baffles are slidably connected to both ends of the outer side of the positioning hollow roller. A flexible hose is fixedly connected to the bottom of the two arc-shaped baffles.
[0007] Preferably, the rectangular groove consists of three horizontal grooves whose transverse length gradually decreases from bottom to top and inclined grooves located on both sides of the horizontal grooves, and the horizontal grooves and inclined grooves are interconnected.
[0008] Preferably, the auxiliary plate assembly consists of a guide plate and a micro motor for controlling the flipping of the guide plate, and the micro motor on the auxiliary plate assembly is electrically connected to a press-type delayed automatic reset switch; The top of the push-button type delayed automatic reset switch is hemispherical.
[0009] Preferably, the motion control module further includes a moving component, the moving component including a limiting frame, the limiting frame being fixed to the side wall of the first plate, and the limiting frame being slidably connected to the first plate via a slider; A hydraulic drive module is fixedly connected to one end of the limiting frame, and the output end of the hydraulic drive module is fixedly connected to the second plate.
[0010] Preferably, a stop rod is slidably connected inside the second plate, one end of the stop rod passing through the second plate and extending into the interior of the rectangular groove, and the stop rod is movably connected to the rectangular groove; The end of the abutment located inside the second plate is elastically connected to the second plate via a first spring.
[0011] Preferably, the upper end of the second plate is fixedly connected to the positioning hollow roller, and the flexible hose is located above the lateral end of the second plate.
[0012] Preferably, the two arc-shaped baffles are elastically connected by a second spring, and a U-shaped frame is abutted to the top of the arc-shaped baffles. An electric telescopic rod is installed at the lower end of the U-shaped frame, and the bottom of the electric telescopic rod is fixedly connected to the outer wall of the positioning hollow roller. The U-shaped frame consists of two parts. The uppermost end is made of rigid material, while the lowermost ends on both sides that abut against the top of the arc-shaped baffle are made of rigid elastic material that bends toward the positioning hollow roller. The positioning hollow roller has an opening for gas flow at the middle of its bottom end.
[0013] Preferably, a suction module is installed at the bottom end of the flexible hose, and the suction module is slidably connected inside the first plate. The suction module draws air from inside the positioning hollow roller through the flexible hose.
[0014] Preferably, the looping module includes two sets of brackets, on which a drive rotation assembly is fixedly connected, and a yarn bobbin is bolted to the center of the drive rotation assembly; The sidewall of the bracket is fixedly connected to the first plate.
[0015] The present invention also proposes a control method for a control device used in the production of fancy yarns, the method comprising the following steps: S1, the fancy yarn is passed through the positioning hollow roller and placed on the yarn bobbin by the fancy yarn making module. The drive rotation component and the hydraulic drive module are started. The drive rotation component winds the yarn through the yarn bobbin. The hydraulic drive module drives the yarn to move back and forth through the second plate and the positioning hollow roller. S2, when the second plate moves inside the rectangular groove by the abutment rod, the abutment rod will move in the bottom transverse groove of the rectangular groove and contact the press-type delayed automatic reset switch. Through the electrical connection with the auxiliary plate assembly, the micro motor drives the auxiliary plate assembly to flip. When the hydraulic drive module drives the second plate to move in the opposite direction, the tilted auxiliary plate assembly after flipping will block and limit the abutment rod moving in the opposite direction, so that the abutment rod moves to the upper transverse groove. When it moves to the other end in the transverse groove, it will be driven to move to the next transverse groove again by the auxiliary plate assembly and the press-type delayed automatic reset switch set in the transverse groove. This process is repeated, so that the positioning hollow roller can drive the fancy yarn to move. With the cooperation of the drive rotation component to wind, the fancy yarn is wound. S3, when the positioning hollow roller moves back and forth, the exhaust module will adsorb the gas inside the positioning hollow roller through the flexible hose and filter tube; S4, the adsorbed gas will carry flocculent impurities generated during long-term operation. At the same time, under the existing tension on the fancy yarn, the adsorption and suppression of the gas will make the fancy yarn in the middle area of the positioning hollow roller. When the electric telescopic rod S5, which controls the up-and-down movement of the U-shaped frame, is started, it will drive the U-shaped frame to gradually descend and make its bottom end abut against the arc-shaped baffle. This causes the bottom ends of the two arc-shaped baffles to gradually move towards each other and reduce the size of the opening at the bottom end of the positioning hollow roller. At this time, the gas inside the positioning hollow roller is sucked in more concentratedly and with greater force until the winding of the fancy yarn ends.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention provides a control device and method for the production of fancy yarns, which can effectively avoid the phenomenon of "collapse" of the fancy yarns at both ends after the winding is completed by the existing fixed linear drive method, making the winding more uniform and compact; at the same time, it can also effectively avoid the problem of the fancy yarns being in constant contact with the rollers during long-term operation, causing wear and tear, and greatly improve the stability control of fancy yarn winding.
[0017] (2) The present invention, through the coordinated cooperation of the abutment rod, the second plate, the rectangular groove and the auxiliary plate assembly, can not only avoid the "collapse" situation to a large extent, but also make the reciprocating movement drive smoother, reduce the cost of use and improve the applicability. Specifically, when the abutment rod moves from one end to the other end inside the initial bottommost horizontal groove, the auxiliary plate assembly and the press-type delayed automatic reset switch will make the abutment rod move in the opposite direction and be sequentially moved to the upper layer of the bottommost horizontal groove through the inclined groove. When it is in this layer and moves to the other end, it will be sequentially moved to the upper layer of the horizontal groove again through the auxiliary plate assembly and the press-type delayed automatic reset switch of this layer. The operation is repeated to ensure the uniformity and compactness of the winding and improve the control performance of the winding.
[0018] (3) Through the coordinated operation of the positioning hollow roller, filter tube and hose, the present invention can ensure that the fancy yarn is always in the middle area of the positioning hollow roller, avoiding long-term contact with the end of the existing roller and causing more wear. It can also apply pressure to the fancy yarn in this area to keep it under a certain tension. Specifically, the gas inside the positioning hollow roller is drawn out by the exhaust module and hose, so that the gas inside the positioning hollow roller will be transported to the inside of the hose through the opening at the lower end of the positioning hollow roller. The flocculated impurities generated inside the positioning hollow roller due to the continuous friction of the fancy yarn during use will be drawn out, thereby improving the stable control of the fancy yarn in the existing roller control area.
[0019] (4) The present invention uses the coordinated cooperation of the U-shaped frame and the flexible hose to control the opening size at the bottom of the positioning hollow roller by driving the U-shaped frame up and down, thereby changing the strength of the suction range inside the positioning hollow roller, and thus changing the pressing strength of the fancy yarn inside the positioning hollow roller, further adjusting the controllability of the fancy yarn in this area.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", and "outer" indicate orientation or positional relationships only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.
[0024] It should be understood that, in the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms “installation,” “connection,” and “linking” should be interpreted broadly.
[0025] Example 1: As Figures 1 to 10 As shown, the present invention provides a control device for fancy yarn production, including a fancy yarn making module 100, and further comprising: The loop yarn module 200 is located on one side of the fancy yarn making module 100; The movement control module 300 is fixedly connected to the loop yarn module 200 on the side near the fancy yarn making module 100; The motion control module 300 includes a positioning component 310 and a stabilization module 330. The positioning component 310 includes a first plate 311 with a rectangular groove 312 inside. An auxiliary plate component 313 and a press-type delayed automatic reset switch 314 are installed on the first plate 311. Multiple sets of auxiliary plate components 313 and press-type delayed automatic reset switches 314 are arranged in a cross-vertical distribution. Each auxiliary plate component 313 and press-type delayed automatic reset switch 314 constitutes a group. The stabilization module 330 includes a positioning hollow roller 331 and a filter tube 332. The filter tube 332 is sleeved inside the positioning hollow roller 331. Arc-shaped baffles 333 are slidably connected to both ends of the outer side of the positioning hollow roller 331. A flexible hose 336 is fixedly connected to the bottom of the two arc-shaped baffles 333.
[0026] The rectangular groove 312 consists of three horizontal grooves whose transverse length gradually decreases from bottom to top and inclined grooves located on both sides of the horizontal grooves. The horizontal grooves and the inclined grooves are interconnected.
[0027] It is easy to understand that the design of the horizontal grooves, whose length gradually decreases from bottom to top, ensures that when the abutment 324 moves from one end of the initial bottommost horizontal groove to the other, it will, through the cooperation of the auxiliary plate assembly 313 and the press-type delayed automatic reset switch 314, be sequentially moved to the upper layer of the bottommost horizontal groove via the inclined groove when moving in the opposite direction. When it is in that layer and moves to the other end, it will be sequentially moved back to the upper horizontal groove by the auxiliary plate assembly 313 and the press-type delayed automatic reset switch 314 of that layer, and in conjunction with... Figure 4 It can be seen that the trapezoidal transverse surface of the rectangular groove 312 allows the fancy yarn to move back and forth during the continuous looping process. The restriction of the rectangular groove 312 prevents the yarn from exhibiting the near-rectangular looping operation in the prior art, which causes the outermost looping yarn to collapse after looping. This makes the middle area of the looping yarn more compact and prevents it from being located too much on the sides. It should be noted that the length and number of transverse slots can be limited according to the actual application.
[0028] The auxiliary plate assembly 313 consists of a guide plate and a micro motor for controlling the flipping of the guide plate. The micro motor on the auxiliary plate assembly 313 is electrically connected to a press-type delayed automatic reset switch 314. The top of the push-type delayed automatic reset switch 314 is hemispherical.
[0029] It should be noted that the push-type delayed automatic reset switch 314 adopts the existing push-reset switch. Its top hemispherical design allows for better contact with the push rod 324, thus enabling the push-type delayed automatic reset switch 314 to descend smoothly when the push rod 324 contacts the push-type delayed automatic reset switch 314. At this time, the downward movement of the push-type delayed automatic reset switch 314 transmits a signal to the PLC control terminal, and through sorting, transmits the opening signal to the micro motor on the auxiliary board assembly 313, causing the micro motor to drive the guide plate on the auxiliary board assembly 313 to flip. After the guide plate flips, its lower end will be tilted and located in the transverse groove. At this time, during the reverse movement, the push rod 324 will be restricted by the flipped guide plate, allowing the push rod 324 to move smoothly to the transverse groove located on the upper layer.
[0030] The motion control module 300 also includes an active component 320, which includes a limiting frame 322. The limiting frame 322 is fixed to the side wall of the first plate 311 and is slidably connected to the first plate 311 by a slider. A hydraulic drive module 323 is fixedly connected to one end of the limiting frame 322, and the output end of the hydraulic drive module 323 is fixedly connected to the second plate 321. It is easy to understand that the limiting frame 322 provides stable lateral limitation for the second plate 321, and the reciprocating movement of the output end of the hydraulic drive module 323 during operation drives the reciprocating movement of the second plate 321.
[0031] The second plate 321 has a sliding connection to a push rod 324. One end of the push rod 324 passes through the second plate 321 and extends into the interior of the rectangular groove 312. The push rod 324 is movably connected to the rectangular groove 312. One end of the stop bar 324 located inside the second plate 321 is elastically connected to the second plate 321 via a first spring 325.
[0032] It should be noted that when one end of the abutment 324 gradually moves upward in the multiple transverse grooves of the rectangular groove 312, the second plate 321 is kept at the same height by the movement of the abutment 324 and the elastic restriction of the first spring 325, so as to carry out stable looping operation.
[0033] The upper end of the second plate 321 is fixedly connected to the positioning hollow roller 331, and the flexible hose 336 is located above the transverse end of the second plate 321.
[0034] Two arc-shaped baffles 333 are elastically connected by a second spring 334. The top of the arc-shaped baffles 333 is connected to a U-shaped frame 335. An electric telescopic rod is installed at the lower end of the U-shaped frame 335. The bottom of the electric telescopic rod is fixed to the outer wall of the positioning hollow roller 331. The U-shaped frame 335 consists of two parts. The uppermost end is made of rigid material, while the lowermost ends on both sides that abut against the top of the arc-shaped baffle 333 are made of rigid elastic material that bends toward the positioning hollow roller 331. The positioning hollow roller 331 has an opening for gas flow at the middle of its bottom end.
[0035] It should be noted that when the electric telescopic rod is running, its output end will drive the U-shaped frame 335 to slowly descend. At this time, the two sides of the lower end of the U-shaped frame 335, which are made of rigid elastic material bent towards the positioning hollow roller 331, will stick tightly to the outer wall of the positioning hollow roller 331 while continuously pressing down the arc-shaped baffle 333. The bottom ends of the two arc-shaped baffles 333 will gradually move towards each other, and the second spring 334 will be in a stretched state. As the two arc-shaped baffles 333 gradually move towards each other at their bottom ends, the opening at the bottom end of the positioning hollow roller 331 gradually narrows. At this time, under the increasing suction pressure of the wind, the fancy yarn is in a suppressed state. At the same time, the wind will also suck out the fibrous impurities generated inside the positioning hollow roller 331 due to the continuous friction of the fancy yarn during use. Under normal use conditions, the combination of its own tension and the wind force suppresses the fancy yarn, so that the fancy yarn is in a more central area of the positioning hollow roller 331. This avoids the situation in the prior art where the fancy yarn directly contacts the end of the guide roller, resulting in greater friction and damage to the fancy yarn.
[0036] A ventilation module 337 is installed at the bottom of the flexible hose 336. The ventilation module 337 is slidably connected inside the first plate 311. The ventilation module 337 draws air from the inside of the positioning hollow roller 331 through the flexible hose 336.
[0037] It should be noted that the contact area between the upper end of the flexible hose 336 and the bottom end of the arc-shaped baffle 333 is made of a relatively soft elastic material, so that the flexible hose 336 can fully support the bottom end of the opening of the positioning hollow roller 331, whether the bottom ends of the two arc-shaped baffles 333 are facing each other or facing away from each other.
[0038] The loop yarn module 200 includes two sets of brackets 210, a drive rotation assembly 220 is fixedly connected to the brackets 210, and a yarn cylinder 230 is bolted to the middle of the drive rotation assembly 220. The side wall of the bracket 210 is fixedly connected to the first plate 311.
[0039] The present invention also proposes a control method for a control device used in the production of fancy yarns, the method comprising the following steps: S1, the fancy yarn is passed through the positioning hollow roller 331 and sleeved on the yarn bobbin 230 by the fancy yarn making module 100. The drive rotation component 220 and the hydraulic drive module 323 are started. The drive rotation component 220 winds up the yarn through the yarn bobbin 230. The hydraulic drive module 323 drives the yarn to move back and forth through the second plate 321 and the positioning hollow roller 331. S2, when the second plate 321 moves inside the rectangular groove 312 via the abutment rod 324, the abutment rod 324 moves in the lowest horizontal groove of the rectangular groove 312 and contacts the press-type delayed automatic reset switch 314. Through the electrical connection with the auxiliary plate assembly 313, the micro motor drives the auxiliary plate assembly 313 to flip. When the hydraulic drive module 323 drives the second plate 321 to move in the opposite direction, the tilted auxiliary plate assembly 313 after flipping will block and limit the abutment rod 324 moving in the opposite direction, so that the abutment rod 324 is sequentially moved into the upper horizontal groove. When it moves to the other end in the horizontal groove, it will be driven to move up to the next horizontal groove again by the auxiliary plate assembly 313 and the press-type delayed automatic reset switch 314 set in the horizontal groove. This process is repeated, so that the positioning hollow roller 331 can drive the fancy yarn to move. With the cooperation of the drive rotation assembly 220 to wind the fancy yarn, the fancy yarn is wound. S3, when the positioning hollow roller 331 moves back and forth, the exhaust module 337 will adsorb the gas inside the positioning hollow roller 331 through the hose 336 and the filter tube 332. S4, the adsorbed gas will carry flocculent impurities generated during long-term operation. At the same time, under the existing tension on the fancy yarn, the fancy yarn is placed in the middle area of the positioning hollow roller 331 by the adsorption and suppression of the gas. When the electric telescopic rod for controlling the up-and-down movement of the U-shaped frame 335 is activated, it will drive the U-shaped frame 335 to gradually descend and make its bottom end abut against the arc-shaped baffle 333, so that the bottom ends of the two arc-shaped baffles 333 gradually move towards each other and reduce the size of the opening at the bottom end of the positioning hollow roller 331. At this time, the gas inside the positioning hollow roller 331 is sucked in more concentratedly and with greater force until the winding of the fancy yarn ends.

A yarn cylinder (230) is bolted to the middle of the drive rotation assembly (220). The side wall of the bracket (210) is fixedly connected to the first plate (311).
10. The control method for the control device for fancy yarn production according to any one of claims 1-9, characterized in that: The method includes the following steps: S1, the fancy yarn is passed through the positioning hollow roller (331) and sleeved on the yarn bobbin (230) by the fancy yarn making module (100). The drive rotation component (220) and the hydraulic drive module (323) are started. The drive rotation component (220) winds up the yarn through the yarn bobbin (230). The hydraulic drive module (323) drives the yarn to move back and forth through the second plate (321) and the positioning hollow roller (331). S2, when the second plate (321) moves inside the rectangular groove (312) via the push rod (324), the push rod (324) moves in the lowest horizontal groove of the rectangular groove (312) and contacts the push-type delayed automatic reset switch (314). Through electrical connection with the auxiliary plate assembly (313), the micro motor drives the auxiliary plate assembly (313) to flip. When the hydraulic drive module (323) drives the second plate (321) to move in the opposite direction, the auxiliary plate assembly (313), which is tilted after flipping, will... The reverse-moving stop bar (324) is blocked and limited, so that the stop bar (324) is sequentially positioned in the upper layer of the transverse groove. When it moves to the other end in the transverse groove, the stop bar (324) will be driven to move up to the next transverse groove by the auxiliary plate assembly (313) and the press-type delayed automatic reset switch (314) set in the transverse groove. This process is repeated, so that the positioning hollow roller (331) drives the fancy yarn to move. With the cooperation of the drive rotation assembly (220) winding, the fancy yarn is wound. S3, when the positioning hollow roller (331) moves back and forth, the exhaust module (337) will adsorb the gas inside the positioning hollow roller (331) through the hose (336) and the filter tube (332); S4, the adsorbed gas will carry flocculent impurities generated during long-term operation. At the same time, under the existing tension on the fancy yarn, the fancy yarn is placed in the middle area of the positioning hollow roller (331) by the adsorption and suppression of the gas. When the electric telescopic rod for controlling the up-and-down movement of the U-shaped frame (335) is started, it will drive the U-shaped frame (335) to gradually descend and make its bottom end abut against the arc-shaped baffle (333), so that the bottom ends of the two arc-shaped baffles (333) gradually move towards each other and reduce the size of the opening at the bottom end of the positioning hollow roller (331). At this time, the gas inside the positioning hollow roller (331) is sucked in more concentrated and stronger force until the winding of the fancy yarn ends.
