Description

Technical Field

[0001] This utility model belongs to the field of yarn winding technology, specifically relating to a cashmere yarn tensioning and winding machine. Background Technology

[0002] Cashmere yarn is a textile thread made from cashmere fibers. After being prepared and formed, cashmere yarn is wound up uniformly by a winding machine. A yarn winding drum is fitted onto the winding roller of the winding machine. The rotating roller directly winds the cashmere yarn onto the winding drum. The cashmere yarn is wound layer by layer onto the winding drum. As the winding process continues, the diameter of the yarn roll gradually increases. This causes the cashmere yarn initially wound on the winding drum to be compressed by the large amount of yarn wound later. It becomes impossible to effectively separate the yarn thickness on the winding drum during the winding process, or to provide support and tension for the yarn in different thickness areas as the roll diameter gradually increases. This results in some of the yarn that is compressed inside becoming brittle and breaking due to the enclosed nature of the area, affecting the storage effect of the wound cashmere yarn.

[0005] The baffle is fixedly connected to the front end of the take-up drum, the rear end of the take-up drum is close to the inner wall of the fixed disc, and the front end of the rotating roller is screwed with a top head, which is close to the outer wall of the baffle.

[0006] The inner wall of the baffle plate has three guide grooves arranged in a ring from the inside to the outside, and the three crossbars are respectively inserted into the three guide grooves.

[0007] The fixed plate has three semi-circular grooves corresponding to the guide grooves, and the three semi-circular blocks are slidably connected inside the three semi-circular grooves.

[0008] The three positioning cylinders are located in front of the three semicircular blocks respectively. A combination plate is fixedly connected to the outer wall of the positioning cylinder. The combination plate is fixedly connected to the front end of the corresponding semicircular block. The other end of the crossbar is inserted into the corresponding positioning cylinder.

[0011] The beneficial effects of this utility model are:

[0012] This invention utilizes a winding assembly fitted around the outside of a rotating roller to wind up cashmere yarn. The yarn is first wound and collected on the outside of a winding drum that rotates with the roller. A drive box controls three mating toothed rods to rotate on the outside of three semi-circular toothed plates. The interaction between the toothed rods and the semi-circular toothed plates controls the rotation of corresponding crossbars on the outside of the winding drum. This allows for the sequential rotation of three crossbars arranged in a ring from the inside out on the outside of the winding drum, effectively adjusting their positions. When the yarn is wound to a specified thickness, the three crossbars rotate, adjust, and position themselves at the outermost layer of the yarn roll, supporting and tensioning the yarn from below as it continues to wind. This allows the yarn roll to continue winding from the outside of the crossbars, effectively separating the yarn thickness on the winding drum during the cashmere yarn winding process. As the roll diameter gradually increases, it provides support and tension for yarns of different thicknesses, increasing the breathability of the compressed yarn portion inside the roll and improving the winding and storage effect of the cashmere yarn.

[0021] Please see Figures 1-6 The present invention provides the following technical solution: including a winding machine body 1, a rotating roller 2 and a drive box 5 rotating on the winding machine body 1, a winding assembly 3 provided on the outside of the rotating roller 2, the winding assembly 3 including a winding drum 31, a baffle 32 and a crossbar 33, the winding drum 31 being sleeved on the outside of the rotating roller 2 to position the baffle 32 and the three crossbars 33 on the outside of the rotating roller 2, a positioning assembly 4 provided on the outside of the rotating roller 2, the positioning assembly 4 including a fixing plate 41, a semi-circular block 42, a positioning cylinder 43 and a semi-circular toothed plate 44, the fixing plate 41 being fixed on the surface of the rotating roller 2 to position the three semi-circular blocks 42, the three positioning cylinders 43 and the three semi-circular toothed plates 44 opposite the crossbars 33 and splice the three crossbars 33.

[0022] In this implementation scheme: the main body 1 of the winding machine controls the rotation of the rotating roller 2 in the front position to perform the winding operation of cashmere yarn through the winding assembly 3 connected to the rotating roller 2.

[0023] The take-up assembly 3 consists of a take-up drum 31, a baffle plate 32, and crossbars 33. The baffle plate 32 is fixedly connected to the front end of the take-up drum 31. Three guide grooves 321, arranged in a ring from the inside out, are formed on the inner wall of the baffle plate 32. The three crossbars 33 are respectively inserted into the three guide grooves 321, stably connecting the take-up drum 31, the baffle plate 32, and the three crossbars 33. The crossbars 33 can move along the groove walls of the guide grooves 321 to adjust their position outside the take-up drum 31. The take-up drum 31 is fitted onto the outside of the rotating roller 2. A top head 21 is screwed to the front end of the rotating roller 2. The top head 21 is pressed against the outer wall of the baffle plate 32, blocking and positioning the baffle plate 32 from the outside, thus effectively positioning the take-up assembly 3 on the rotating roller 2.

[0024] The positioning component 4 is positioned opposite the winding component 3. The positioning component 4 consists of a fixed disk 41, semicircular blocks 42, a positioning cylinder 43, and a semicircular toothed plate 44. The fixed disk 41 is fixedly connected to the surface of the rotating roller 2. The rear end of the winding cylinder 31 is pressed against the inner wall of the fixed disk 41 to effectively position and reinforce the winding component 3 on the rotating roller 2, ensuring that the winding component 3 smoothly follows the rotation of the rotating roller 2 to smoothly wind up the cashmere yarn. There are three semicircular blocks 42, three positioning cylinders 43, and three semicircular toothed plates 44. The fixed disk 41 has three semicircular grooves 411 corresponding to the guide grooves 321. The three semicircular blocks 42 are slidably connected inside the three semicircular grooves 411, allowing the semicircular blocks 42 to move along the groove wall inside the corresponding semicircular groove 411. Three positioning cylinders 43 are located in front of three semicircular blocks 42. A combination plate 431 is fixedly connected to the outer wall of the positioning cylinder 43. The combination plate 431 is fixedly connected to the front end of the corresponding semicircular block 42, stably connecting the positioning cylinder 43 in front of the corresponding semicircular block 42. The other end of the crossbar 33 is inserted into the interior of the corresponding positioning cylinder 43 to facilitate the combination and positioning of the three crossbars 33 and the three positioning cylinders 43, and to laterally position the crossbar 33 between the baffle plate 32 and the fixed plate 41. Three semicircular toothed plates 44 are fixedly connected to the rear end of the three semicircular blocks 42. The semicircular toothed plates 44 are located on the back of the fixed plate 41, and can effectively position the three semicircular blocks 42, the three positioning cylinders 43 and the three semicircular toothed plates 44 opposite the crossbar 33, so as to splice and position the three crossbars 33 during the process of connecting the winding assembly 3 to the rotating roller 2.

[0025] The drive box 5 is located on the back of the fixed disk 41. A fixing block 52 is fixedly connected to the outer wall of the drive box 5. The fixing block 52 is fixedly connected to the back of the fixed disk 41, so that the drive box 5 is stably connected to the back of the fixed disk 41 and the semi-circular toothed plate 44. Three mating gears 51 are fixedly connected to the drive box 5. The three mating gears 51 mesh with the outer walls of the three semi-circular toothed plates 44 respectively. The three mating gears 51 are connected to three sets of drive components in the drive box 5 respectively, so that the three mating gears 51 can rotate on the outer side of the three semi-circular toothed plates 44 under the control of the three drive components in the drive box 5. Through the meshing between the semi-circular toothed plates 44 and the mating gears 51, the semi-circular toothed plates 44 are guided by the semi-circular blocks 42 and the semi-circular grooves 411 to rotate behind the fixed plate 41, so as to adjust the position of the semi-circular toothed plates 44 and the semi-circular blocks 42. The semi-circular blocks 42 rotate on the outer side of the take-up drum 31 through the positioning cylinder 43 with the corresponding crossbar 33, adjusting the position of the crossbar 33.

[0026] The take-up assembly 3 is fitted onto the outside of the rotating roller 2. The main body 1 of the take-up machine controls the rotating roller 2 to rotate, causing the take-up assembly 3 to rotate and gradually wind the cashmere yarn onto the take-up assembly 3. The take-up drum 31 is fixed to the front end of the rotating roller 2 by the top head 21, which is pressed and positioned on the outside of the rotating roller 2. The yarn is first wound and collected on the outside of the take-up drum 31, which rotates with the rotating roller 2. After winding a certain thickness of yarn, the rotating roller 2 stops working. The drive box 5 controls the mating toothed bar 51, which is in the innermost position, to rotate on the outside of the corresponding semi-circular toothed plate 44. The mating toothed bar 51 and the semi-circular toothed plate 44 can control the crossbar 33, which is in the innermost position, to rotate on the outside of the take-up drum 31, effectively adjusting the position of the crossbar 33. This allows the crossbar 33, which is in the innermost position, to rotate to the outermost position of the yarn roll. The rotating roller 2 continues to work, allowing the yarn to continue to be wound from above the crossbar 33. The three crossbars 33 can rotate and position themselves at the outermost layer of the yarn roll when the yarn is wound to a specified thickness. They support and tension the yarn from below the continuing to wind the yarn, allowing the yarn roll to continue winding from the outside of the crossbars 33. This effectively separates the yarn thickness on the winding drum 31 during the winding process of cashmere yarn, and supports and tensions the yarn in different thickness areas as the roll diameter gradually increases. This increases the air permeability of the compressed yarn inside the yarn roll, preventing the compressed yarn from becoming brittle or breaking due to the airtightness of the area, and improving the winding and storage effect of cashmere yarn.
