Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, specifically to an anti-overlapping constant tension auxiliary mechanism and a slitting warping machine. Background Technology

[0002] Slitting warping machines are key equipment in the textile industry for achieving orderly yarn winding and forming. These machines are typically equipped with anti-overlapping and constant tension auxiliary mechanisms, which guide the yarn during the warping process, ensuring even distribution on the roller surface and maintaining a constant and stable yarn conveying tension. This effectively prevents defects such as yarn stacking, compression, deformation, and tension fluctuations during winding. It reduces waste yarn and broken yarn, lowers raw material losses and additional energy consumption from rework processes, and ensures smooth operation of subsequent weaving processes. Furthermore, it aligns with the textile industry's requirements for energy conservation, emission reduction, and green, low-carbon production development.

[0003] Currently, in the warping and winding process of yarn, one end of the yarn is usually knotted into a ball and placed inside the round hole of the roller. Since the position of the opening on the outer wall of the roller remains fixed, the yarn tends to accumulate along the same axis during continuous winding, forming overlapping bulges. When the stacking thickness reaches 3 to 5 times the yarn diameter or more, significant compression occurs between the yarn layers. As the stacking height further increases, the upper layer of yarn continuously compresses the lower layer, easily causing the yarn to flatten, bend, pill, or even undergo localized plastic deformation. In severe cases, hard overlapping ridges are formed, affecting the smoothness of subsequent unwinding and the weaving quality. Furthermore, most existing warping equipment uses multiple independent power sources to drive the transverse movement mechanism and the roller rotation mechanism separately. Each power unit operates independently with poor coordination and matching, resulting in a large overall power redundancy and significant imbalances in no-load and working conditions. This not only leads to complex equipment structures and large space requirements but also high energy consumption and severe power loss, making it difficult to achieve energy conservation, emission reduction, and low-carbon production, which is inconsistent with the development trend of green manufacturing and energy conservation and environmental protection in the textile industry. To address the aforementioned yarn overlap defects, existing technologies mostly adjust the transmission ratio between the traverse speed and the roller speed to change the yarn winding spacing and reduce regular overlap. However, this type of structure can only change the winding spacing once in the initial state and cannot dynamically adjust it during the winding process. It cannot fundamentally solve the process problems such as yarn overlap and yarn layer compression deformation, nor can it optimize the high energy consumption and high losses caused by multiple power sources. Overall, its performance and energy-saving effect are poor, failing to meet the dual requirements of high-quality warping winding and energy-saving and environmentally friendly production. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies and solve the problem of yarn accumulating along the same axis during winding, this invention proposes an anti-overlapping constant tension auxiliary mechanism and a slitting warping machine.

[0005] The technical solution adopted by the present invention to solve its technical problem is: the anti-overlapping yarn constant tension auxiliary mechanism of the present invention includes: a working box, a driving component, an anti-overlapping yarn component, an adjusting component, a balancing component and an anti-flake component, wherein the number of the working boxes is two; The anti-overlapping yarn assembly has two states: tension and compression. It includes an arc-shaped rod that is spiral-shaped and arranged between the two working boxes on opposite sides. The driving component can drive the arc-shaped rod to rotate in both directions. The adjustment component can work in conjunction with the driving component. When the driving component rotates forward, the arc-shaped rod is in a compressed state. When the driving component rotates in reverse, the arc-shaped rod is reset and stretched. The balancing component, located below the anti-overlapping component, is able to maintain constant tension during yarn transport. The anti-flocculent component is fixedly connected to the adjustment component and works in conjunction with the balance component to prevent flocculent material from adhering to the inside of the arc-shaped rod.

[0006] Preferably, the driving component includes a positive generator and a rotating shaft. The positive and negative generators are fixed to the side wall of one of the working boxes, and the rotating shaft is movably inserted between opposite sides of the two working boxes. The output end of the positive and negative generators is fixedly connected to one end of the rotating shaft.

[0007] Preferably, the anti-overlapping yarn assembly further includes two first gears, which are respectively fixed at both ends of the rotating shaft. Each working box has a cylinder movably inserted into its inner wall, and each cylinder has a second gear sleeved at its front end. Each second gear meshes with a corresponding first gear.

[0008] Preferably, a circular shell is fixedly fitted at the end of each cylinder, a first groove is formed on the inner wall of each circular shell, a plate is slidably provided inside each first groove, and the arc-shaped rod is fixed between the opposite sides of the two plates.

[0009] Preferably, the adjusting assembly includes two lead screws with opposite thread directions. Both lead screws are fixedly sleeved on the outer wall of the rotating shaft and are located inside a corresponding working box. Each lead screw has a threaded plate rotatably connected to its outer wall. Each threaded plate has a vertical rod fixedly connected to its top. Each vertical rod has a ring fixedly sleeved on its top. Each ring has a closed slide.

[0010] Preferably, each of the cylinders has a second groove on its outer wall, a first crossbar is movably inserted inside each of the cylinders, a round block is fitted at the front end of each first crossbar, each ring is movably fitted on the outer wall of a corresponding cylinder, a block is connected to the outer wall of each round block, and each block is movably restricted in a corresponding closed slide, and the end of each first crossbar passes through a corresponding round shell and is fixedly connected to a corresponding plate.

[0011] Preferably, the balancing assembly includes a bracket, which is fixed between two opposite sides of the two working boxes. The bracket is movably sleeved on the outer wall of the rotating shaft. A set of electric telescopic rods is fixedly installed on the top of the bracket. An arc-shaped plate is fixedly sleeved between the shaft ends of the set of electric telescopic rods. Two arc-shaped shells are equidistantly placed on the outer wall of the arc-shaped plate. A set of round holes is opened on the upper surface of each arc-shaped shell. The outer wall of each arc-shaped shell is covered with a sponge board.

[0012] Preferably, the anti-flocculent component includes two strip shells, which are respectively fixed on the front and back sides of the bracket. The outer wall of each strip shell is connected to a one-way valve connector pipe, and the top of each strip shell is connected to a rubber hose. The liquid outlet end of each rubber hose passes through the lower wall of a corresponding arc-shaped shell and is connected to the interior of the arc-shaped shell.

[0013] Preferably, a set of second crossbars is fixedly connected to one side of each of the threaded plates. The end of each second crossbar passes through a corresponding strip shell and is fitted with a square plate, which is movably placed inside the corresponding strip shell. A block is fixedly connected to the outer wall of each second crossbar. A diagonal bar is hinged to the top of each block. A strip plate is hinged between the tops of every two diagonal bars. Both strip plates are located below the arc plate.

[0014] The present invention also provides a slitting warping machine, including the aforementioned anti-overlapping constant tension auxiliary mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Most existing technologies reduce regular overlap by adjusting the transmission ratio between the traverse speed and the winding drum speed to change the yarn winding pitch. However, this type of structure can only change the winding pitch once in the initial state and cannot be dynamically adjusted during the winding process. This makes it difficult to fundamentally solve the problems of yarn overlap and yarn layer compression deformation, and cannot meet the requirements of high-quality warping winding. This technology, through the coordinated operation of a drive component, an anti-overlapping component, and an adjustment component, addresses these issues. The spiral arc-shaped rod of the anti-overlapping component rotates in both directions under the drive component, guiding the yarn to move back and forth. Combined with the reverse screw structure of the adjustment component, the pitch of the arc-shaped rod is dynamically adjusted during the winding process, overcoming the limitations of existing technologies that only address the overlapping pitch once. This device overcomes the shortcomings of initial spacing adjustment and lack of dynamic intervention, avoiding single-point clustering and regular overlap of yarns. It solves the problems of yarn stacking and yarn layer compression deformation, resulting in dense and uniform subsequent yarn winding and improved structural strength. The winding quality is stable and reliable, meeting the requirements of warping winding and significantly improving production yield and efficiency. This device adopts a single power source to drive the entire mechanism for synchronous linkage, abandoning the traditional layout of multiple motors driving independently. This reduces the number of power equipment configurations, lowers no-load energy consumption and power matching losses, and achieves higher mechanical transmission coordination and lower power loss. It effectively simplifies energy output and saves electricity costs, while realizing the production effects of equipment simplification, consumption reduction and green energy saving.

[0019] 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.

[0020] Please see Figure 1 and Figure 4 As shown, an anti-overlapping yarn constant tension auxiliary mechanism includes: a working box 100, a driving component 200, an anti-overlapping yarn component 300, an adjusting component 400, a balancing component 500, and an anti-flake component 600, wherein there are two working boxes 100.

[0021] It should be noted that, as Figure 12 As shown, K is the take-up cylinder and L is the yarn body. The mechanism is placed laterally on one side of the take-up cylinder, and the two are parallel to each other. The yarn body is initially placed at one end of the arc-shaped rod 307 and is located in the spiral structure of the arc-shaped rod 307.

[0022] like Figures 1-2As shown, the drive unit 200 includes a positive generator and a rotating shaft. The positive and negative motors are fixed to the side wall of a work box 100. The rotating shaft is movably inserted between the opposite sides of the two work boxes 100. The output end of the positive and negative motors is fixedly connected to one end of the rotating shaft.

[0023] When using, combine Figure 1 and Figure 2 Clearly define the connection between the rotating shaft and the working box 100, turn on the forward and reverse motors, and the power can be directly applied to the rotating shaft to complete the subsequent power transmission.

[0024] like Figures 1-2 and Figure 4 As shown, the anti-overlapping yarn assembly 300 has two states: tension and compression. It includes an arc-shaped rod 307, which is spiral-shaped and arranged between two opposite sides of the working boxes 100. The driving component 200 can drive the arc-shaped rod 307 to rotate in both directions. The anti-overlapping yarn assembly 300 also includes two first gears 301, which are fixed at both ends of the rotating shaft. A cylinder 303 is movably inserted into the inner wall of each working box 100. A second gear 302 is sleeved at the front end of each cylinder 303. Each second gear 302 is meshed with a corresponding first gear 301. A circular shell 304 is fixedly sleeved at the end of each cylinder 303. A first groove 305 is opened on the inner wall of each circular shell 304. A plate 306 is slidably arranged inside each first groove 305. The arc-shaped rod 307 is fixed between two opposite sides of the two plates 306.

[0025] When using, combine Figure 2 and Figure 4 The rotating shaft, driven by the forward and reverse motors, transmits power to the connected mechanical components to drive the arc-shaped rod 307 to rotate synchronously. During this process, the yarn located at one end of the arc-shaped rod 307 will continuously move towards the other end of the arc-shaped rod 307 under the guidance of the spiral structure of the arc-shaped rod 307. When it moves to the farthest distance, the motor rotates in the opposite direction until the yarn returns to its initial position. This physical intervention is used to prevent the yarn from clustering at a single point.

[0026] like Figures 2-3 and Figures 5-6As shown, the adjusting component 400 can be linked with the driving component 200. When the driving component 200 rotates forward, the arc-shaped rod 307 is in a compressed state. When the driving component 200 rotates in reverse, the arc-shaped rod 307 is reset and stretched. The adjusting component 400 includes two lead screws 401 with opposite thread directions. Both lead screws 401 are fixedly sleeved on the outer wall of the rotating shaft and are located inside a corresponding work box 100. Each lead screw 401 has a threaded plate 402 rotatably connected to its outer wall. Each threaded plate 402 has a vertical rod 403 fixedly connected to its top. Each vertical rod 403 has a fixed top. Each cylinder 303 is fitted with a ring 404, each ring 404 having a closed slide. Each cylinder 303 has a second groove 406 on its outer wall. Each cylinder 303 has a first crossbar 407 movably inserted inside. Each first crossbar 407 has a round block 405 fitted at its front end. Each ring 404 is movably fitted on the outer wall of a corresponding cylinder 303. Each round block 405 has a block connected to its outer wall, and each block is movably restricted in a corresponding closed slide. The end of each first crossbar 407 passes through a corresponding round shell 304 and is fixedly connected to a corresponding plate 306.

[0027] When using, combine Figure 4 Because the two lead screws 401 have opposite thread directions, they are used to realize the relative or opposite movement of the two threaded plates 402, combined with Figure 5 The purpose is to make the two first crossbars 407 move in the same direction. When the motor is rotating forward, the two first crossbars 407 move relative to each other to push the end plate 306. At this time, the arc-shaped rod 307 is compressed. When the motor is rotating in reverse, the arc-shaped rod 307 is reset and stretched. This effect is used to control the pitch width of the arc-shaped rod 307 and adjust the path shape of the yarn winding onto the take-up cylinder. The yarn is wound onto the surface of the take-up cylinder in an irregular form to eliminate the adjacent gaps caused by regular winding, improve the structural strength of the subsequent spooled yarn, and avoid loosening.

[0028] like Figure 1 , Figure 3 and Figures 7-11As shown, the balancing component 500, located below the anti-overlapping yarn component 300, maintains constant tension during yarn transport. The balancing component 500 includes a bracket 501 fixed between opposite sides of the two working boxes 100. The bracket 501 is movably fitted onto the outer wall of the rotating shaft. A set of electric telescopic rods 502 is fixedly installed on the top of the bracket 501. An arc-shaped plate 503 is fixedly fitted between the shaft ends of the set of electric telescopic rods 502. Two arc-shaped shells 504 are equidistantly placed on the outer wall of the arc-shaped plate 503. Each arc-shaped shell 504 has a set of round holes 505 on its upper surface. Each arc-shaped shell 504 is covered with a sponge plate 506. The anti-lint component 600 is fixedly connected to the adjusting component 400 and works in conjunction with the balancing component 500 to prevent lint from adhering to the inside of the arc-shaped rod 307. The anti-lint component 600 includes two strip-shaped shells. 601, two strip shells 601 are fixed to the front and back sides of the bracket 501 respectively. The outer wall of each strip shell 601 is connected to a one-way valve connector pipe 602. The top of each strip shell 601 is connected to a rubber hose 603. The liquid outlet end of each rubber hose 603 passes through the lower surface wall of a corresponding arc shell 504 and is connected to the interior of the arc shell 504. A set of second crossbars 604 is fixedly connected to the opposite side of each threaded plate 402. The end of each second crossbar 604 passes through a corresponding strip shell 601 and is fitted with a square plate 605, which is movably placed inside the corresponding strip shell 601. A block 606 is fixedly connected to the outer wall of each second crossbar 604. A diagonal bar 607 is hinged to the top of each block 606. A strip plate 608 is hinged between the tops of every two diagonal bars 607. Both strip plates 608 are located below the arc plate 503.

[0029] It should be noted that during the compression process, the material of the arc-shaped rod 307 experiences mechanical shaking due to extrusion, and the body rotates at a fixed point during the process.

[0030] First linkage state, combined with Figure 4 and Figure 8 Before yarn guiding begins, the electric telescopic rod 502 is activated to raise the height of the arc-shaped plate 503, bringing the arc-shaped rod 307 into contact with the surface of the arc-shaped plate 503. When the motor rotates forward, the two threaded plates 402 move relative to each other, and the inclined rod 607, connected to the second crossbar 604, slowly rises. This aims to bring the strip plate 608 and the arc-shaped plate 503 into contact and push them upwards. As the compression of the arc-shaped rod 307 increases, the swaying amplitude intensifies. Utilizing the support effect of the strip plate 608 on the arc-shaped plate 503 enhances the restraining strength of the arc-shaped plate 503 on the arc-shaped rod 307. Figure 9 and Figure 10 The purpose of this method is to limit the sway of the curved rod 307, avoid jump wire problems, and ensure the stability of the guide path.

[0031] Second linkage state: Combination Figure 8 The square 606 extends into the strip shell 601 to drive the square plate 605 to squeeze the liquid inside. Due to the material properties of the rubber hose 603, it can stretch as the arc plate 503 is raised. After being squeezed, the liquid is conveyed into the arc shell 504 through the rubber hose 603 and then evenly discharged through a set of round holes 505, adsorbed into the structure of the sponge plate 506. This liquid is an antistatic liquid, mainly composed of four parts: solvent, active antistatic agent, film-forming resin, and auxiliary additives. Its core function is to quickly conduct the static charge generated by the friction contact of the yarn and avoid static accumulation. Since the yarn is conveyed laterally and the two sponge plates 506 are located on both sides of the arc rod 307, the working height of the winding roller is reasonably set so that the continuously entering yarn can come into contact with the sponge plate 506 that has fully absorbed the antistatic liquid, causing some of the detached fluff to lose its adsorption capacity, thereby inhibiting the fluff from adhering to the structure of the arc rod 307.

[0032] Working principle: Preparation stage: The mechanism moves to the side of the adaptive take-up cylinder and combines... Figure 12 Pull one end of the yarn across the mechanism and the take-up cylinder, and fix the end to the designated position on the take-up cylinder, ensuring that the yarn is located at the front end of the arc-shaped rod 307 and the main body is fully placed in the spiral structure of the arc-shaped rod 307.

[0033] During the collection and guidance phase, combined with Figures 1-2 and Figure 4 The motor is turned on and acts on the rotating shaft, driving the first gear 301 to rotate in the forward direction. Utilizing the meshing connection between the first gear 301 and the second gear 302, the power is continuously transmitted to the next level. The cylinder 303 drives the arc-shaped rod 307 in the shell 304 to rotate synchronously. Before this, the take-up roller rotates at a constant speed under external power, and the yarn can be straightened. Guided by the spiral structure of the arc-shaped rod 307, the yarn continues to move towards the end of the arc-shaped rod 307 and forms a complete winding trajectory on the surface of the take-up roller. Subsequently, the mature system controls the motor to reverse, and the yarn is wound back onto the surface of the take-up roller in the opposite direction.

[0034] During the path change phase, combined with Figure 2 and Figures 4-6Because the threads on the surfaces of the two lead screws 401 are opposite, when the motor rotates forward, the two threaded plates 402 connected to them retract relative to each other. During this process, when the cylinder 303 rotates, because the ring 404 is in a movable sleeve connection with it, the block 405 is constrained by the closed slide rail, preventing it from escaping the ring 404's restriction. This does not affect the synchronous rotation of the built-in first crossbar 407 and the cylinder 303. When the two threaded plates 402 move relative to each other, the vertical rod 403 connected to them moves synchronously, aiming to drive the two first crossbars 407. The relative movement forces a thrust onto the plate 306. Utilizing the movable connection between the first groove 305 and the plate 306, the two plates 306 move relative to each other to slowly compress the arc-shaped rod 307, causing the thread pitch of the arc-shaped rod 307 to gradually decrease. Under this interference with the yarn path, when the motor rotates forward, the yarn pitch on the front and back of the take-up drum continuously decreases. Conversely, when the motor rotates in reverse and all structures reset, the yarn pitch on the front and back of the take-up drum continuously increases.

[0035] In the auxiliary phase, combined with Figures 9-11 Before the yarn is guided, the electric telescopic rod 502 is activated to raise the height of the arc plate 503. During this process, the rubber hose 603 connected to the strip shell 601 will be pulled. Thanks to the material's extensibility, the length can be stretched. When the arc plate 503 contacts the arc rod 307, the lifting action stops. At this time, the sponge plates 506 are distributed on both sides of the arc rod 307. The position of the take-up roller is adjusted again, and the yarn is guided in to ensure that the yarn can contact the sponge plates 506 on both sides of the arc rod 307. When the arc rod 307 is continuously compressed, the swaying and deviation generated during the process will be continuously physically blocked by the arc plate 503, reducing the amplitude of the jump.

[0036] It is important to note that, in combination Figure 4 When the two threaded plates 402 move relative to each other, they simultaneously drive the connected second crossbar 604 to move. The inclined bar 607 connected to the block 606 can be lifted up, expanding the angle between the second crossbar 604 and the inclined bar 607, thereby increasing the height of the strip plate 608. Ultimately, it can fully contact the lower arc surface of the arc plate 503, strengthening the main support effect of the arc plate 503.

[0037] During the electrostatic treatment stage, combined with Figure 4 When the two threaded plates 402 move relative to each other, they engage. Figure 8 The synchronously moving second crossbar 604 continues to penetrate deeper into the strip-shaped shell 601, driving the square plate 605 to compress the antistatic liquid inside the strip-shaped shell 601, combined with... Figures 10-11The overflowing liquid is transported to the arc-shaped shell 504 by the rubber hose 603. After the liquid is filled, it overflows from each set of round holes 505 and acts on the sponge plate 506. A large amount of liquid can be absorbed by the structure of the sponge plate 506. When the continuously passing yarn comes into contact with the wet sponge plate 506, it can quickly conduct away the static charge generated by the friction contact of the yarn, including some of the fly lint that is subsequently detached, so that it loses its adhesive ability and prevents the fly lint from adhering to the structure of the arc-shaped rod 307.

[0038] In summary, the tension generated by yarn conveying is mainly produced by the yarn feeding equipment and the take-up roller. This mechanism is set between the two and mainly provides path planning effect, applying lateral physical external forces to the yarn body, thus weakening the longitudinal pulling force, ensuring relative tension balance, and preventing yarn breakage.
