Description

Technical Field

[0001] This invention relates to the field of yarn winding technology, specifically a yarn winding device after waxing. Background Technology

[0002] The yarn production process generally includes carding, spinning, waxing, and winding. After waxing, the yarn usually needs to be wound up to facilitate its transfer, storage, and use. During the yarn winding process, a winding device is usually used to wind the yarn.

[0003] Traditional winding devices have the following problems: After winding is completed, the winding device needs to be stopped to facilitate manual disassembly and replacement of the wound yarn bobbin. If the yarn is wound after waxing, the waxing device also needs to be stopped to ensure the uniformity of waxing. If the waxing device is not stopped, the waxed yarn will be continuously fed out and cannot be wound, or the yarn will stop being fed out and a certain part of the yarn will be continuously waxed, affecting the overall production quality of the yarn. Summary of the Invention

[0004] The purpose of this invention is to provide a technical solution for a yarn winding device after waxing, so as to solve the technical problem in the prior art that after the yarn is wound, the winding device needs to be stopped for processing, so as to facilitate manual disassembly and replacement of the wound yarn spool, and the yarn cannot be continuously wound.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a yarn winding device after waxing, comprising a frame, wherein a drive component is provided on the frame to guide the yarn to reciprocate and wind.

[0006] The frame is symmetrically equipped with rotating parts, and at least two take-up drums are rotatably mounted between the rotating parts along the axial direction. The take-up drums are detachably connected to the rotating parts.

[0007] The winding drum is equipped with a locking part for fixing the ends of the yarn;

[0008] A cutting blade is installed between at least two take-up drums. The cutting blade is used to cut the yarn between two adjacent take-up drums after either take-up drum has been wound and the yarn has been secured by the engagement part of the other take-up drum.

[0009] According to the above technical solution, the present invention can continuously wind up the yarn without stopping the machine after waxing, and there is no need for manual cutting of the yarn. The entire winding, cutting and rewinding process is fully automated, which greatly improves the production quality of the yarn and increases the production efficiency of the yarn.

[0010] Preferably, the cutting blade includes at least two cutting edges, the center point of the cross-section of the cutting blade is located on the central axis of the rotating part, and the width of each cutting edge is at least smaller than the radius of the winding drum after winding is completed;

[0011] After the yarn is fixed in place by the engaging part of the winding drum, the yarn between the two adjacent winding drums is driven to contact the blade by the rotating part.

[0012] According to the above technical solution, through the cooperation between at least two take-up drums and the design of the cutting blade, when the yarn is being wound up, the take-up drum can engage the yarn, causing the yarn to come into contact with the cutting blade, thereby achieving automatic cutting of the yarn. After cutting, the yarn can continue to be wound up. The whole process requires no additional operation and has high automation efficiency.

[0013] Preferably, the orientation of any blade is perpendicular to the line connecting the center points of the cross-sections of two adjacent winding drums.

[0014] According to the above technical solution, the cutting blade can better cut the yarn, ensuring a smoother process of winding, cutting, and rewinding.

[0015] Preferably, the take-up drum has a shuttle-shaped hollow structure, with the locking part located in the middle section of the take-up drum. The locking part is configured with at least two sets, with any set of locking parts arranged around the same circumference of the take-up drum. The locking direction of the locking part on the yarn end is respectively towards both ends of the take-up drum.

[0016] According to the above technical solution, the shuttle-shaped take-up drum, combined with the locking parts designed in the middle section of the take-up drum facing the locking parts at both ends, makes it easier for the locking parts to lock the yarn, ensuring smoother switching of the take-up drum and avoiding failure to lock the yarn, which would lead to take-up and cutting failure.

[0017] Preferably, the engaging part has an open design, with the width of the opening gradually decreasing from the outside to the inside, and the width at the bottom of the opening being less than the diameter of the yarn.

[0018] According to the above technical solution, the locking part can securely fix the yarn.

[0019] Preferably, the drive component is provided with a tensioning element, and the tensioning element is circumferentially arranged with a number of independently rotatable axles;

[0020] The tensioner has an elliptical cross-section, and planar spiral springs are provided at the connection points between the tensioner and the drive component on both sides.

[0021] In the relaxed state of the planar spiral spring, the angle between the major axis of the tensioner and the vertical plane is α, the bottom of the tensioner is inclined towards the winding drum, and the axle at the bottom of the tensioner away from the winding drum is the force axis.

[0022] According to the above technical solution, when the winding drum winds up the yarn, it can tighten the yarn through the short axis direction of the tensioning member. Because during the winding process, the winding drum is located at the top of the rotating part, and the tensioning force increases. In order to ensure the tensioning force is as constant as possible, it is necessary to tighten through the short axis direction of the tensioning member.

[0023] When cutting the yarn after winding is completed, the winding drum is located in the middle of the rotating part, and the tension force is reduced. In order to ensure a constant tension force, it is necessary to tighten it through the long axis of the tensioning part to ensure the tension force and avoid the situation where the yarn is loose and cannot be locked by the locking part, so as to ensure the smooth winding and cutting.

[0024] Preferably, when the tensioner tensions the yarn, the yarn passes through the inside of the force-bearing shaft.

[0025] According to the above technical solution, the yarn passes through the inside of the force shaft, so that when the yarn is wound by the winding drum, the entire tensioning member can be driven to rotate by the increased tension force, and the tensioning operation is performed through the short axis direction of the tensioning member, thereby ensuring that the tension force is constant throughout the tensioning process.

[0026] Preferably, one end of the winding drum is detachably connected to the output shaft of the central motor, and the other end is detachably connected to the bearing via a rotating shaft. The central motor is mounted on the rotating component, and the bearing is mounted on the rotating component via a bearing housing.

[0027] According to the above technical solution, the take-up drum can be disassembled and the take-up drum can be easily replaced after the winding is completed, thereby realizing continuous winding of yarn.

[0028] Preferably, slots are provided on both the rotating shaft and the output shaft of the central motor, and clamps are provided at both ends of the winding drum, with clamps on the clamps that are compatible with the slots.

[0029] Both the rotating shaft and the output shaft of the central motor are fitted with threaded sleeves, and both ends of the winding drum are fitted with nuts that are threadedly connected to the threaded sleeves.

[0030] The threaded sleeve has a receiving cavity that is aligned with the direction of the slot.

[0031] According to the above technical solution, the design of the slot and the block allows for a more stable installation of the winding drum, ensuring the stability of the winding drum after installation.

[0032] Preferably, a limiting ring is provided on the outside of the receiving cavity, and a limiting plate is provided on the clamping head. When the clamping block is inserted into the clamping groove, the limiting ring and the limiting plate interact to limit the axial displacement of the winding drum.

[0033] The above technical solution further ensures the stability of the take-up drum after installation. Since the yarn slides on the surface of the take-up drum when it is engaged, the axial displacement is limited, which can ensure the stability of the take-up drum during the yarn engagement process.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] This invention, through the design of a rotating component, combined with a winding drum and a cutting blade, enables continuous winding of yarn without stopping the machine after waxing, and eliminates the need for manual yarn cutting. The entire winding, cutting, and rewinding process is fully automated, greatly improving the quality and efficiency of yarn production.

[0036] The present invention also achieves adaptive adjustment of tension force during yarn winding by using a tensioning element with an elliptical cross-section, as well as a wheel axle and a planar spiral spring, to ensure that the tension force remains as constant as possible during winding and yarn cutting, thus ensuring smooth yarn winding.

[0037] This invention, through the design of slots and blocks, along with threaded sleeves and nuts, enables the disassembly and replacement of the winding drum, further ensuring the possibility of continuous winding and improving the winding efficiency of yarn. Attached Figure Description

[0056] 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.

[0057] Example: This invention provides a yarn winding device after waxing, mainly for the yarn winding process after waxing during yarn production. The yarn is waxed by spraying or dipping, such as... Figure 1 As shown, the winding device includes a frame 100, which has a U-shaped structure. Two rotating parts 200 are symmetrically arranged on the inner top of the frame 100. The rotating parts 200 can be designed as a disc or other structures, which can be set according to actual production needs. The rotating parts 200 are connected to the frame 100 by bearings, which facilitates the rotation of the rotating parts 200 by a servo motor.

[0058] Two take-up drums 300 are installed between symmetrically arranged rotating components 200. The central axis of the take-up drums 300 is parallel to the central axis of the rotating components 200. One end of the take-up drums 300 is rotatably connected to the rotating components 200 through a bearing seat 303, and the other end is connected to a central motor 302. The central motor 302 is embedded in the rotating components 200. An external power supply is also provided on the rotating components 200 to provide power to the central motor 302.

[0059] Specifically, such as Figures 11-13 As shown, a bearing is installed inside the bearing housing 303, and a rotating shaft 304 is installed at the center of the bearing. Both the rotating shaft 304 and the output shaft of the centrally mounted motor 302 have slots 305. A locking head 306 is provided at both ends of the take-up drum 300, and a locking block 307 adapted to the slot 305 is provided on the locking head 306, allowing the locking block 307 to be directly inserted into the slot 305 during installation of the take-up drum 300. Simultaneously, a threaded sleeve 308 is installed on the outside of the rotating shaft 304 and the output shaft of the centrally mounted motor 302, and the threaded sleeve 308 has a locking mechanism inside. The slots 305 face the receiving cavity 310, so that when the locking block 307 is inserted into the slot 305, the locking head 306 can be placed in the receiving cavity 310, ensuring the stability of the winding drum 300 installation. A sliding nut 309 is also sleeved on the outside of the locking head 306. When the locking block 307 is inserted into the slot 305, by sliding the nut 309 and turning the nut 309, the threaded connection between the nut 309 and the threaded sleeve 308 can be achieved to securely install the winding drum 300, ensuring that the winding drum 300 will not loosen during the rotation and winding process.

[0060] In this embodiment, preferably, a limiting ring is provided on the outside of the threaded sleeve 308, and a limiting plate is provided on the chuck 306. When the chuck block 307 is inserted into the chuck groove 305, the limiting plate can be placed into the receiving cavity 310 together. The diameter of the limiting plate is larger than the inner diameter of the limiting ring, so that the axial movement of the winding drum 300 can be restricted by the limiting plate and the limiting ring, further ensuring the stability of the winding drum 300 after installation.

[0061] It should be noted that, as Figures 8-9As shown, the take-up drum 300 has a shuttle-shaped hollow structure. A locking part 301 is provided in the middle section of the take-up drum 300. The locking part 301 is designed in at least two sets, which are distributed around the same circumference of the take-up drum 300. This allows the locking part 301 to be used to fix the yarn end better. The locking part 301 is designed with an opening. The width of the opening gradually decreases from the outside to the inside. The width of the bottom of the opening is smaller than the diameter of the yarn, making it easier for the yarn to be fixed by the locking part 301. The openings of the locking part 301 face the two ends of the take-up drum 300. When fixing the yarn end, under the action of the driving component 500, the yarn will inevitably slide from one end of the take-up drum 300 to the other end on the surface of the take-up drum 300, making it easier to fix the yarn by the locking part 301.

[0062] With the design of the shuttle-shaped hollow structure, and the locking part 301 opening towards both ends, when the driving part 500 drives the yarn to be in the middle of the take-up drum 300, the rotating part 200 is driven to rotate by the servo motor. This can further ensure that the locking part 301 accurately fixes the yarn, and will not affect the subsequent winding of the yarn by the take-up drum 300.

[0063] In this embodiment, the winding device performs the following process for winding, cutting, and rewinding the yarn: Figures 2-5 As shown.

[0064] The process from the initial stage to the completion of winding 300 pairs of yarn on any take-up drum is as follows: Figure 2 As shown, both take-up drums 300 are mounted on the rotating component 200, and the two take-up drums 300 are arranged vertically on the rotating component 200. First, the waxed yarn end is manually fixed to the take-up drum 300 through the locking part 301. Then, the take-up drum 300 is driven to rotate by the central motor 302. At the same time, the tensioning part 600 is driven to reciprocate along the axis of the take-up drum 300 by the driving component 500, so that the yarn can be evenly wound on the take-up drum 300. The take-up drum 300 rotates clockwise and counterclockwise to wind the yarn until the diameter of the yarn wound on the take-up drum 300 reaches the set condition, thus completing the winding operation of the yarn by the take-up drum 300.

[0065] At this time, as Figure 3As shown, the servo motor drives the rotating component 200 to rotate clockwise until the two take-up drums 300 are in a horizontally distributed state. In this state, the yarn is still wound on the take-up drum 300 that has been wound. However, since the two take-up drums 300 are horizontally distributed, the yarn will come into contact with the surface of the take-up drum 300 to be wound. Here, "to be wound" refers to the take-up drum 300 that has not yet been wound but is about to be wound with the yarn. At this time, the driving component 500 will still drive the yarn on the tensioner 600 to reciprocate on the surface of the take-up drum 300 to be wound. Due to the opening design of the engaging part 301, when the yarn slides on the surface of the take-up drum 300 to be wound, it will be engaged inside the engaging part 301.

[0066] The yarn, which is then fixed by the take-up drum 300, will continue to be wound on the surface of the take-up drum 300, such as... Figure 4 As shown, the yarn between the two take-up drums 300 has one end fixed to the already wound take-up drum 300 and the other end fixed by the engaging part 301 of the take-up drum 300 to be wound. As the take-up drum 300 to be wound rotates, the yarn will transfer from the surface of the already wound take-up drum 300 to the surface of the take-up drum 300 to be wound. At this time, the cutting blade 400 set between the two take-up drums 300 will come into contact with the yarn and cut the yarn.

[0067] It should be noted that the cutting blade 400 includes at least two blades. The center point of the cross-section of the cutting blade 400 is located on the central axis of the rotating member 200. The width of any blade is at least smaller than the radius of the winding drum 300 after winding. The purpose is to prevent the yarn from contacting the blades of the cutting blade 400 when the yarn is not fixed by the engaging part 301 of the winding drum 300. This avoids the yarn being cut before it is fixed by the winding drum 300, which would prevent the yarn from being fixed by the engaging part 301 due to the lack of tension between the winding drum 300 and the winding drum 300.

[0068] When the yarn is cut by the 400-degree cutting blade, as Figure 5 As shown, the servo motor continues to drive the rotating part 200 to rotate until the take-up drum 300 to be wound rotates to the top of the rotating part 200. The wound take-up drum 300 can be manually removed and replaced with a new take-up drum 300. Similarly, after the wound take-up drum 300 is removed and a new take-up drum 300 is replaced, the servo motor can be used to rotate the take-up drum 300 to be wound to the top of the rotating part 200.

[0069] Once the above process is completed, the yarn winding process is finished. During the entire winding process, the waxing equipment and winding device do not need to be stopped, and continuous segmented winding can be completed, which can greatly improve the efficiency of yarn winding and at the same time ensure the quality of the yarn.

[0070] In this embodiment, the driving component 500 is designed as a threaded screw. Specifically, a threaded screw and a limiting rod are arranged at the bottom of the frame 100 along the axis of the take-up drum 300. The threaded screw is driven to rotate by a servo motor. A sliding block is sleeved on the outside of the threaded screw and the limiting rod. The sliding block is threadedly connected to the threaded screw and slidably connected to the limiting rod. When the servo motor drives the threaded screw to rotate, the sliding block can reciprocate on the threaded screw. A support frame is provided on the sliding block. A tensioning member 600 is provided at the end of the support frame away from the sliding block. The yarn is tensioned by the tensioning member 600 before being wound by the take-up drum 300 to ensure the tightness of the yarn after winding.

[0071] In order to achieve adaptive adjustment of yarn tension through tensioner 600, such as Figure 10 As shown, the tensioner 600 has an elliptical cross-section. Several independently rotatable axles 601 are arranged circumferentially around the tensioner 600. These axles 601 reduce the friction between the yarn and the tensioner 600, preventing wear on the yarn surface. Simultaneously, a planar spiral spring 602 is provided at the connection between the tensioner 600 and the support frame. Figure 7 As shown, in the relaxed state of the planar spiral spring 602: the angle between the major axis of the tensioner 600 and the vertical plane is α. For example, the angle α can be designed to be 20°. The bottom of the tensioner 600 is inclined towards the winding drum 300. The axle 601 at the bottom of the tensioner 600 away from the winding drum 300 is the force-bearing shaft 603. When the tensioner 600 tensions the yarn, the yarn passes through the inside of the force-bearing shaft 603. Figure 6 As shown, the force-bearing shaft 603 is designed so that when the take-up drum 300 is winding the yarn, the yarn can drive the tensioner 600 to compress the planar spiral spring 602 and rotate, causing the short shaft of the tensioner 600 to tension the yarn, thus avoiding affecting the normal winding operation of the take-up drum 300. When the take-up drum 300 needs to be switched, since the two take-up drums 300 are in a horizontally distributed state, the tension of the yarn will decrease. Under the action of the planar spiral spring 602, the tensioner 600 will be driven to return to its initial state, and the long shaft of the tensioner 600 will tension the yarn, thereby increasing the tension of the yarn and preventing the yarn from being too loose and unable to be fixed by the locking part 301. This ensures the smooth switching of the take-up drum 300 during the yarn winding process and guarantees the normal production process of the yarn.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
