[0002] Yarn-forming equipment is used in the spinning process to convert fibers into yarn. It typically includes spinning machines, twisting machines, and spinning frames. Spinning machines process fibrous raw materials into roving, twisting machines process roving into finer yarn with higher twist, and spinning frames process finer yarn into even finer yarn. After the yarn is formed, it needs to be wound up and stored, which requires the use of winding equipment.

[0021] Beneficial effects

[0022] This invention provides a yarn forming device and process for preparing blended yarns. Compared with the prior art, it has the following advantages:

[0023] 1. A yarn forming device and process for preparing mixed yarn, comprising a servo motor fixedly connected to the back of a side plate, the output shaft of the servo motor rotating through the side plate and fixedly connected to a take-up shaft via a coupling, a take-up frame for taking up yarn being detachably connected to the outer wall of the take-up shaft, and a first gear fixedly sleeved on the side of the outer wall of the take-up shaft away from the take-up frame, with a chain meshing on the outer wall of the first gear, a spare take-up roller for guiding yarn take-up being rotatably connected to the left side of the front of the side plate, and a yarn cleaning mechanism for cleaning yarn being provided on the right side of the front of the side plate. This solves the problems of current yarn forming efficiency, where the yarn surface has a lot of short fibers and dust adhering to it during the forming process, which directly affects the sale and subsequent use of the yarn, the yarn diameter is small, manual cleaning is not thorough, and the yarn is easily broken during the cleaning process.

[0024] 2. A yarn forming device and process for preparing mixed yarn, comprising a yarn cleaning mechanism that, when the yarn passes through the guide tube, utilizes a high-speed airflow ejected from annularly distributed nozzles to ensure the yarn passes through the center of the air cylinder. The nozzles are bent and face inwards towards the air cylinder. The ejected airflow blows off dust and short fibers from the yarn surface and directs them into the guide tube. Furthermore, the inclusion of a first conical tube and a second conical tube prevents the collected short fibers from escaping. Secondly, the airflow ejected from the nozzles prevents the yarn from contacting the inner wall of the air cylinder, reducing friction and effectively preventing wear due to friction, thus providing a good guiding effect.

[0025] 3. A yarn forming device and process for preparing mixed yarn, wherein a dust collection component is provided to collect short fibers blown off by the fiber guiding component into the dust collection cylinder. The pressure plate moves back and forth within a certain height range under the action of an electric push rod, and the short fibers can enter the dust collection cylinder for storage through the conical through hole. As the amount of short fibers increases until they contact the bottom of the conical sealing cover, the short fibers are pressed down by the bottom of the conical sealing cover, and the fluffy short fibers can be squeezed into blocks, reducing their volume occupation, thereby storing more fibers in a certain period of time. Furthermore, an outlet is provided at the bottom of the dust collection cylinder, which allows the collected short fibers to be collected after the work is completed for easy reuse next time.

[0026] 4. A yarn forming device and process for preparing mixed yarn, wherein a first guide component and a second guide component are connected by a transmission belt, and a second gear in the first guide component is connected to the first gear by a chain, thereby enabling the yarn cleaning mechanism to work synchronously by utilizing the power of the servo motor during winding, saving the cost of setting up a drive device for the yarn cleaning mechanism, while making the structure simpler and facilitating subsequent inspection and maintenance.

Detailed Implementation

[0040] 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.

[0041] This invention provides three technical solutions:

[0042] like Figure 1-4 The first embodiment is shown: a yarn forming device for preparing mixed yarn includes a side plate 1, a servo motor 2 fixedly connected to the back of the side plate 1, the output shaft of the servo motor 2 rotatably passes through the side plate 1 and is fixedly connected to a take-up shaft 3 through a coupling, a take-up frame 6 for taking up yarn is detachably connected to the outer wall of the take-up shaft 3, and a first gear 4 is fixedly sleeved on the side of the outer wall of the take-up shaft 3 away from the take-up frame 6, a chain 5 is meshed on the outer wall of the first gear 4, a spare take-up roller 7 for guiding yarn take-up is rotatably connected to the left side of the front of the side plate 1, and a yarn cleaning mechanism 8 for cleaning yarn is provided on the right side of the front of the side plate 1. The yarn cleaning mechanism 8 includes a fiber guiding component 81, a connecting tube 82 fixedly connected to the bottom of the fiber guiding component 81, and a first guiding component 83 and a second guiding component 84 detachably mounted at both ends of the fiber guiding component 81 by bolts. The connecting tube 82 is internally connected to the fiber guiding component 81 and is used to discharge the collected yarn fibers. A dust collection component 86 for storing yarn fibers is threadedly connected inside the connecting tube 82. The first guiding component 83 and the second guiding component 84 are powered by a transmission belt 85. The transmission belt 85 is connected to the outer wall of two pulleys 837 in the first guiding component 83 and the second guiding component 84. The fiber guiding component 81 includes a guiding tube 811 and a first tapered tube 812 and a second tapered tube 813 fixedly connected to both sides inside the guiding tube 811. Baffles 814 are fixedly sleeved on the outer wall of the first tapered tube 812 and the second tapered tube 813 and located inside the first tapered tube 812. A threaded tube 815 for conveying short yarn fibers is fixedly connected at the bottom of the guiding tube 811 and between the two baffles 814.

[0043] like Figure 5-8The second embodiment is shown, and its main difference from the first embodiment is that: a yarn forming device for preparing mixed yarn, the first guide assembly 83 includes an air cylinder 831 and an annular air pipe fixedly connected inside the air cylinder 831, and air nozzles 832 uniformly fixedly connected inside the air cylinder 831. All air nozzles 832 are connected to the annular air pipe. An air supply pipe 833 connected to the annular air pipe is fixedly connected to one side of the bottom of the air cylinder 831. A drive shaft 834 is rotatably connected inside the air supply pipe 833. A fan blade 835 is fixedly connected to one end of the drive shaft 834 and located inside the air supply pipe 833. A second gear 836 and a pulley 837 are fixedly connected to the other end of the drive shaft 834 and located outside the air supply pipe 833. The first guide assembly 83 and the second guide assembly 84 are identical in structure except for the structure of the second gear 836. A drive belt 85 is sleeved on the outer wall of the pulley 837 in the first guide assembly 83 and the second guide assembly 84.

[0044] like Figure 9-12The third embodiment is shown, and its main difference from the second embodiment is that: a yarn forming device for preparing mixed yarns, the dust collection assembly 86 includes a dust collection cylinder 861 and filter holes 862 evenly distributed on the side wall of the dust collection cylinder 861, and an outlet at the bottom of the dust collection cylinder 861. A sealing plug 863 is threadedly connected inside the outlet. The outer wall of the top port of the dust collection cylinder 861 has a thread that matches the inner wall of the threaded tube 815 for easy connection of the dust collection cylinder 861. A through groove 864 is provided on the side wall of the dust collection cylinder 861 below the filter holes 862 for the sliding block 865 to move up and down. The sliding space is provided, and a slider 865 is slidably connected inside the through groove 864. A connecting rod 866 is fixedly connected to the outer wall of the slider 865. An electric push rod 867 is fixedly connected to the bottom end of the connecting rod 866. The electric push rod 867 is fixedly connected to the outer wall of the dust collection cylinder 861 and is controlled by the controller. The electric push rod 867 reciprocates and cyclically pushes the pressure plate 868 up and down. The pressure plate 868 is slidably connected inside the dust collection cylinder 861. A conical through hole 869 is opened at the bottom of the pressure plate 868. A conical sealing cover 8610 is slidably connected inside the conical through hole 869. The conical sealing cover 8610 and the conical through hole 869 are connected to each other. When the conical sealing cover 8610 is not subjected to external force, the spring force of the spring 8613 pushes the lifting rod 8611 downward, creating a gap between the conical sealing cover 8610 and the conical through hole 869. This allows the collected short fibers to pass through the gap into the dust collection cylinder 861 until the dust collection cylinder 861 stores enough short fibers and provides resistance to the bottom of the conical sealing cover 8610. As the conical sealing cover 8610 moves downward, it seals the gap to prevent the short fibers from escaping through the gap during the downward pressing process. The top of the conical sealing cover 8610 remains fixed. A lifting rod 8611 is fixedly connected. A spring baffle 8612 is fixedly sleeved on the outer wall of the lifting rod 8611. A spring 8613 is slidably sleeved on the outer wall of the lifting rod 8611 above the spring baffle 8612. Two support frames 8614 are slidably sleeved on the outer wall of the lifting rod 8611 at the top of the spring 8613 and the bottom of the spring baffle 8612, respectively. The support frames 8614 are fixedly connected to the inside of the pressure plate 868. A slider 865 is fixedly connected to the outer wall of the pressure plate 868 and is used to control the lifting and lowering of the pressure plate 868. A dust collection cylinder 861 is threadedly connected to the inside of a threaded tube 815. A chain 5 is respectively sleeved on the outer wall of the first gear 4 and the second gear 836 and is used to drive the drive shaft 834 to rotate.

[0045] This invention also provides a process for a yarn forming apparatus for preparing blended yarns, the specific process including the following steps:

[0046] Step 1: First, the take-up frame 6 is fitted onto the outer wall of the take-up shaft 3, and the take-up frame 6 and the take-up shaft 3 are fixed with bolts to ensure that the take-up frame 6 remains stable during the yarn winding process. By setting up the yarn cleaning mechanism 8, when the yarn passes through the guide tube 811, the high-speed airflow sprayed by the annularly distributed air nozzles 832 can make the yarn pass through the middle position of the air cylinder 831. The air nozzles 832 are bent and the nozzles face the inside of the air cylinder 831. The sprayed airflow can blow off the dust and short fibers on the surface of the yarn and let them enter the guide tube 811. The first conical tube 812 and the second conical tube 813 can prevent the collected short fibers from "escaping". Secondly, the airflow sprayed by the air nozzles 832 can prevent the yarn from contacting the inner wall of the air cylinder 831, reduce friction, and thus effectively prevent self-wear due to friction, thereby playing a good guiding role.

[0047] Step 2: Pass the yarn to be wound through the yarn cleaning mechanism 8 and wind it around the outer wall of the winding frame 6. Use the control box located on the front of the side plate 1 to control the servo motor 2 to start. When the winding frame 6 rotates, it winds up the yarn. The dust collection component can collect the short fibers blown off by the fiber guiding component inside the dust collection cylinder. The air is discharged through the filter hole 862. The pressure plate 868 moves back and forth within a certain height range under the action of the electric push rod 867. The short fibers can enter the dust collection cylinder 861 through the conical through hole 869 for storage. As the amount of short fibers increases, they will come into contact with the bottom of the conical sealing cover 8610. The short fibers will be compressed into blocks by the bottom of the conical sealing cover 8610, reducing their volume and thus storing more fibers in a certain period of time. Furthermore, the dust collection cylinder 861 has an outlet at the bottom, which can collect the short fibers after the work is completed for easy reuse.

[0048] Step 3: After the yarn passes through the yarn cleaning mechanism 8, short fibers and dust on the yarn surface are blown off and collected. The yarn is then connected to the first guide assembly and the second guide assembly by a transmission belt. The second gear in the first guide assembly is connected to the first gear by a chain, so that the power of the servo motor during winding can synchronously drive the yarn cleaning mechanism. The chain 5 transmits the power of the first gear 4 to the second gear 836, so that the drive shaft 834 can drive the fan blade 835 to rotate and deliver air into the air supply pipe 833. This saves the cost of setting up a drive device for the yarn cleaning mechanism 8, and at the same time makes the structure simpler and facilitates subsequent inspection and maintenance. After use, the dust collection assembly 86 can be unscrewed for cleaning because it is connected to the connecting pipe 82 by a thread.

[0049] In step two, servo motor 2 rotates at a low and constant speed of 5 r / min.
