Description

Technical Field

[0001] This invention patent relates to the field of spinning technology, and more specifically, to a yarn winding unit, production equipment and method with the unit. Background Technology

[0002] Twin-winding is the untwisted combination and winding of two or more yarns together for use in subsequent spinning. In the prior art, when winding yarn, multiple strands of yarn are usually fed to the winding bobbin through the yarn feeding mechanism, and the winding bobbin is rotated under the drive of the rotating mechanism, so that the multiple strands of yarn are wound on the surface of the winding bobbin to complete the winding.

[0003] Once the surface of the yarn bobbin is saturated with yarn, the bobbin needs to be removed and replaced with a new one for reuse. Existing yarn winding equipment typically uses a rotating and pressing motor to drive the grippers to rotate and move them away from each other, thus placing the yarn bobbin in a designated position. A feeding mechanism then installs a new yarn bobbin onto the grippers and limits its position when the grippers reset, thus starting the next work cycle. However, this mechanism for replacing the yarn bobbin is not convenient for limiting yarn bobbins of different sizes, making it difficult to wind yarn or different yarns onto different yarn bobbins, which has certain shortcomings. To solve the above problems, a yarn winding unit, production equipment with this unit, and method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a yarn winding unit, production equipment and method with such unit. In order to overcome the shortcomings of the prior art, this invention provides a yarn winding unit, production equipment and method with such unit, which facilitates the limiting of winding bobbins of different sizes, thereby facilitating the winding of yarn onto winding bobbins of different sizes, making it convenient for practical use, and does not affect the replacement of winding bobbins.

[0005] The present invention is implemented as follows: a yarn winding unit includes a machine body and a winding mechanism disposed on the front of the machine body. The winding mechanism includes winding components arranged in a rectangular array and a servo motor for driving the winding components to rotate. The output shaft of the servo motor is fixedly connected to the rotating shaft of the machine body through a coupling. The winding components are disposed on the side wall of the rotating shaft.

[0006] The yarn winding assembly includes a mounting sleeve fixedly sleeved on the side wall of the rotating shaft, a gripper that is slidably connected to the top and bottom of the outer wall of the mounting sleeve and is mirror-symmetrical about the center point of the mounting sleeve for gripping the yarn winding cylinder, a limiting component for removing the yarn winding cylinder from the gripper after the yarn winding is completed, and an adjusting component for adjusting the position of the gripper.

[0007] Furthermore, the adjustment assembly includes a groove formed on the outer wall of the mounting sleeve, a mounting base fixedly disposed on the inner wall of the bottom of the groove, and a threaded rod rotatably connected to the mounting base and extending to both sides of the mounting base. Inside the groove, a slider is placed in a mirror image of the center point of the groove. The side of the slider away from the groove is fixedly connected to the gripper. Threaded sleeves are threaded to both ends of the outer wall of the threaded rod. Connectors are fixedly disposed on the outer walls of the threaded sleeves. A limiting plate, slidably connected to the inner wall of the bottom of the groove, is fixedly disposed on the side of the connecting plate away from the threaded sleeve. Limiting rods, fixedly connected to the inner walls of both sides of the groove, are fixedly sleeved on both sides of the mounting base and inside the threaded rod. The two ends of the sidewalls of the limiting rods are respectively sleeved inside the sliders. Springs are sleeved on the sidewalls of the limiting rods on the sides of the gripper that are far apart from each other.

[0008] Furthermore, the adjustment assembly also includes a worm gear rotatably connected to the top of the mounting base. A worm wheel extending to the top of the mounting base is fixedly sleeved on the side wall of one end of the threaded rod located inside the mounting base. The worm wheel meshes with the worm gear, and a groove for sleeved worm wheel is provided on the top of the mounting base.

[0009] Furthermore, the threaded rod has a hollow design, and the threaded directions on both sides of the mounting base are opposite. The connecting piece is sleeved on the outer wall of the threaded rod and the limiting rod, and the side of the limiting plate away from the connecting piece is in contact with the side wall of the slider.

[0010] Furthermore, both sides of the outer wall of the mounting sleeve are rotatably connected to connecting seats that are fixedly connected to the machine body. The connecting seats are sleeved on the side wall of the rotating shaft. The limiting component includes a limiting block fixedly disposed on the front of the connecting seat and a traction rope fixedly disposed on the outside of the gripper. The end of the traction rope away from the gripper is wrapped and fixed to the side wall of the limiting block.

[0011] Furthermore, the yarn winding assembly also includes a compression assembly for limiting the spring. The compression assembly includes a baffle that is threaded to both ends of the side wall of the limiting rod. Both ends of the side wall of the baffle and the side wall of the limiting rod are provided with mutually compatible threads. The baffle is located on the side of the spring away from the gripper. The compression assembly and the adjustment assembly are mirror-symmetrical about the center point of the mounting sleeve.

[0012] Furthermore, the yarn winding assembly also includes a mounting rod fixedly disposed on the inner side of the gripper, with the central axis of the mounting rod coinciding.

[0013] Furthermore, a production equipment with a yarn winding unit, employing the aforementioned yarn winding unit, further includes a first and a second through slot opened on the front of the machine body and located at the top and bottom of the winding mechanism, a feeding part located on the front of the machine body and located at the bottom of the first through slot, an feeding part located on the front of the machine body and located at the bottom of the second through slot, and a rotating part located on the front of the machine body and located at the bottom of the feeding part for driving the winding bobbin placed on the gripper to rotate.

[0014] Furthermore, a method for using a yarn winding unit and a production equipment with such unit, employing the aforementioned production equipment with a yarn winding unit, specifically includes the following steps;

[0015] S1: Adjust the spacing between the clamps according to the size of the yarn winding bobbin and adjust the components to suit different sizes of yarn winding bobbins;

[0016] S2: After the adjustment component is adjusted, the limiting component is used to adjust the limiting degree of the gripper to make it suitable for use with yarn winding bobbins of the same size;

[0017] S3: After the limit component is adjusted, the yarn passes through the second through groove and the upper yarn part, and is wound around the yarn winding cylinder on the claw under the drive of the rotating part, thereby winding the yarn.

[0018] S4: After the yarn winding is completed, the servo motor rotates, causing the yarn winding cylinder on the gripper to fall into the second through groove under the action of the limiting component, and roll through the second through groove to the designated storage position to complete the removal of the yarn winding cylinder;

[0019] S5: After removing the completed winding bobbin, the feeding section pushes the unwound winding bobbin onto the gripper, and the servo motor drives the gripper to reset, starting the next winding cycle.

[0020] Compared with the prior art, the present invention has the following beneficial effects;

[0021] 1. This invention uses an adjusting component to move the grippers relative to each other, which facilitates the placement of yarn winding bobbins of different sizes in the feeding section. This makes it easy to wind yarn onto yarn winding bobbins of different sizes, making it convenient to use according to actual yarn winding needs. Furthermore, during the rotation of the grippers, the limiting component causes the grippers to move outward under the constraint of the traction rope, thereby disengaging the completed yarn winding bobbin from the mounting rod and removing the yarn winding bobbin. By adjusting the length of the traction rope, it is convenient to use after adjusting the position of the grippers with the adjusting component.

[0022] 2. The adjusting component of the present invention uses a spring to squeeze and limit the slider, thereby squeezing and limiting the gripper, improving the stability of the gripper, and further improving the stability of limiting the yarn winding cylinder. This facilitates the rotation of the rotating part to drive the yarn winding cylinder, thus facilitating yarn winding. Furthermore, by adjusting the position of the baffle through the squeezing component, the degree of squeezing of the spring by the baffle can be adjusted, making it easier to adjust the spring's movement space. This ensures the supporting and squeezing effect of the spring on the slider and gripper during long-term use, improving the stability of yarn winding on the yarn winding cylinder.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] Example 1

[0036] Please read Figure 1 , Figure 2 and Figure 3A yarn winding unit includes a machine body 1 and a winding mechanism 2 disposed on the front of the machine body 1. The winding mechanism 2 includes winding components 22 arranged in a rectangular array and a servo motor 21 for driving the winding components 22 to rotate. The output shaft of the servo motor 21 is fixedly provided with a rotating shaft that is rotatably connected to the machine body 1 through a coupling. The winding components 22 are disposed on the side wall of the rotating shaft.

[0037] Please read Figure 2 and Figure 3 The yarn winding assembly 22 includes a mounting sleeve 226 fixedly sleeved on the side wall of the rotating shaft, a gripper 224 slidably connected to the top and bottom of the outer wall of the mounting sleeve 226 and mirror-symmetrical about the center point of the mounting sleeve 226 for gripping the yarn winding cylinder, a limiting assembly 223 for removing the yarn winding cylinder from the gripper 224 after the yarn winding is completed, and an adjusting assembly 221 for adjusting the position of the gripper 224.

[0038] Please read Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The adjusting assembly 221 includes a groove 2211 formed on the outer wall of the mounting sleeve 226, a mounting base 2212 fixedly disposed on the inner wall of the bottom of the groove 2211, and a threaded rod 2213 rotatably connected to the mounting base 2212 and extending to both sides of the mounting base 2212. A slider, mirror-symmetrical about the center point of the groove 2211, is placed inside the groove 2211. The side of the slider away from the groove 2211 is fixedly connected to a gripper 224. Threaded sleeves 2217 are threadedly connected to both ends of the outer wall of the threaded rod 2213. Connecting members 2218 are fixedly disposed on the outer wall of each threaded sleeve 2217. A limiting plate 2219, slidably connected to the inner wall of the bottom of the groove 2211, is fixedly disposed on the side of the connecting member 2218 away from the threaded sleeve 2217. The mounting base 2212 is located on both sides of the threaded rod. The internal fixed sleeve of 2213 is equipped with limiting rods 2216 that are fixedly connected to the inner walls of both sides of the slide groove 2211. The two ends of the side wall of the limiting rod 2216 are respectively sleeved in the slider. The limiting rods 2216 limit the slider, improve the stability of the movement of the slider and the gripper 224, and do not affect the normal rotation of the threaded rod 2213. The side wall of the limiting rod 2216 and the side of the gripper 224 that is far away from each other are equipped with springs. The adjusting assembly 221 also includes a worm 2214 that is rotatably connected to the top of the mounting base 2212. The side wall of the threaded rod 2213 located in the mounting base 2212 is fixedly sleeved with a worm wheel 2215 that extends to the top of the mounting base 2212. The worm wheel 2215 meshes with the worm 2214. The top of the mounting base 2212 has a groove for the worm wheel 2215.

[0039] In practical implementation, rotating the worm 2214 drives the worm wheel 2215 to rotate, and the worm wheel 2215 simultaneously drives the threaded rod 2213 to rotate. Since the threaded directions of the threaded rod 2213 on both sides of the mounting base 2212 are opposite, the rotation of the threaded rod 2213 causes the threaded tubes to move relative to each other. The threaded tubes, through the connector 2218, drive the limiting plate 2219, which is slidably connected to the bottom inner wall of the slide groove 2211, to move relative to each other. The limiting plate 2219 pushes the slider to move relative to each other, thereby driving the grippers 224 to move relative to each other. This facilitates the placement of yarn bobbins of different sizes in the grippers 224 by the feeding part 7, making it convenient. The yarn is wound onto winding bobbins of different sizes, facilitating the winding process according to actual needs. Under the action of the spring, the slider is squeezed and limited, thereby squeezing and limiting the gripper 224, improving the stability of the gripper 224, and thus improving the stability of the winding bobbin limit. This makes it easier for the rotating part 4 to drive the winding bobbin to rotate, facilitating the winding process. Furthermore, under the action of the spring and the limiting component 223, it is easy to remove the completed winding bobbin from the gripper 224, so that a new winding bobbin can be installed on the gripper 224. The transmission method using worm gear 2215 and worm 2214 has a self-locking function, improving the stability of the adjustment component 221 after adjustment.

[0040] The threaded rod 2213 has a hollow design. The threads on both sides of the mounting base 2212 are opposite. The connector 2218 is sleeved on the outer wall of the threaded rod 2213 and the limiting rod 2216. The side of the limiting plate 2219 away from the connector 2218 is in contact with the side wall of the slider to avoid uneven contact between the slider and the limiting plate 2219, which facilitates the movement of the slider and improves the stability of the movement.

[0041] Please read Figure 4 Both sides of the outer wall of the mounting sleeve 226 are rotatably connected to the connecting seat 222 which is fixedly connected to the body 1. The connecting seat 222 is sleeved on the side wall of the rotating shaft. The limiting component 223 includes a limiting block 2231 fixedly disposed on the front of the connecting seat 222 and a traction rope 2232 fixedly disposed on the outside of the gripper 224. The end of the traction rope 2232 away from the gripper 224 is wrapped and fixed to the side wall of the limiting block 2231.

[0042] In practical implementation, after the yarn winding bobbin on the gripper 224 has finished winding, the servo motor 21 is started. The output shaft of the servo motor 21 drives the rotating shaft to rotate through the coupling, thereby driving the mounting sleeve 226 and the gripper 224 to rotate, so that the gripper 224 approaches the first through slot 6. During the rotation of the gripper 224, the gripper 224 is squeezed by the spring under the restraint of the traction rope 2232 and moves outward, thereby disengaging the completed yarn winding bobbin from the mounting rod 225, and then removing the yarn winding bobbin and dropping it into the second through slot 5, which facilitates the removal of the completed yarn winding bobbin. The yarn bobbin is removed, and the length of the traction rope 2232 is adjusted to facilitate use after the position of the clamp 224 is adjusted by the adjustment component 221. After the yarn bobbin is removed, the new yarn bobbin is installed on the mounting rod 225 under the action of the feeding part 7. When the yarn feeding part 3 pushes the new yarn bobbin to the side wall of the mounting rod 225, the servo motor 21 drives the clamp 224 to reset, the restraint of the traction rope 2232 is reduced, and the clamp 224 moves closer under the action of the spring, so that the new yarn bobbin is sleeved on the side wall of the mounting rod 225 and then installed on the clamp 224.

[0043] Please read Figure 7 The yarn winding assembly 22 also includes a compression assembly 227 for limiting the spring. The compression assembly 227 includes a baffle 2271 that is threaded to both ends of the side wall of the limiting rod 2216. Both ends of the side wall of the baffle 2271 and the side wall of the limiting rod 2216 are provided with mutually compatible threads. The baffle 2271 is located on the side of the spring away from the clamp 224. The compression assembly 227 and the adjustment assembly 221 are mirror-symmetrical about the center point of the mounting sleeve 226.

[0044] In practice, the baffle 2271 is rotated to adjust its position, thereby adjusting the degree of compression of the spring by the baffle 2271. This facilitates the adjustment of the spring's movement space, ensuring the spring's support and compression effect on the slider and gripper 224 during long-term use.

[0045] The yarn winding assembly 22 also includes a mounting rod 225 fixedly disposed inside the gripper 224. The central axis of the mounting rod 225 coincides, which facilitates the installation of the yarn winding bobbin and does not affect the rotation of the rotating part 4 to drive the yarn winding bobbin to rotate.

[0046] Please read Figure 1 A production device with a yarn winding unit is provided. The production device with the yarn winding unit further includes a first through groove 6 and a second through groove 5 opened on the front of the machine body 1 and located at the top and bottom of the winding mechanism 2, a feeding part located on the front of the machine body 1 and located at the bottom of the first through groove 6, a yarn feeding part 3 located on the front of the machine body 1 and located at the bottom of the second through groove 5, and a rotating part 4 located on the front of the machine body 1 and located at the bottom of the yarn feeding part 3 for driving the winding bobbin placed on the gripper 224 to rotate.

[0047] A yarn winding unit and a method of using production equipment with the same unit, the method specifically includes the following steps:

[0048] S1: Adjust the spacing between the clamps 224 according to the size of the yarn winding bobbin and adjust the spacing between the clamps 224 by adjusting the component 221 to suit the use of yarn winding bobbins of different sizes;

[0049] S2: After the adjustment component 221 is adjusted, the limiting component 223 is used to adjust the limiting degree of the clamp 224 so that it can be used for yarn winding bobbins of the same size.

[0050] S3: After the limiting component 223 is adjusted, the yarn passes through the second through groove 5 and the upper yarn part 3 and is wound around the yarn winding cylinder on the claw under the drive of the rotating part 4, thereby winding the yarn.

[0051] S4: After the yarn winding is completed, the servo motor 21 rotates, causing the yarn winding cylinder on the gripper 224 to fall into the second through groove 5 under the action of the limiting component 223, and roll through the second through groove 5 to the designated storage position to complete the removal of the yarn winding cylinder.

[0052] S5: After removing the completed winding bobbin, the feeding unit 7 pushes the unwound winding bobbin onto the gripper 224, and the servo motor 21 drives the gripper 224 to reset, and the next winding cycle begins.
