Description

Technical Field

[0001] This invention relates to the field of yarn preparation equipment technology, specifically to a blended yarn preparation system and spinning process. Background Technology

[0002] Blended yarn refers to yarn spun from two or more different fibers mixed in a certain proportion, such as polyester-cotton blended yarn and polyester-viscose blended yarn. After the blended yarn is produced and processed, it needs to be wound up. The following problems exist in the winding process of blended yarn: After the blended yarn is processed and formed, there may be fuzz on its surface. After the blended yarn is processed and formed, it will be dyed and printed according to actual needs. The presence of fuzz affects both the smoothness of the surface of the blended yarn and the dyeing and printing effect. Fuzz will cause unevenness of the fabric surface during the subsequent weaving process, affecting the quality of the fabric.

[0003] Chinese Patent CN113697598B discloses a blended yarn conveying and winding device with delinting function. The background art addresses the following problem: In traditional collection and winding processes, the blended yarns are loosely wound, causing them to slip off the collection device and affecting the winding effect. This device uses a first and second hot-press roller in conjunction to perform hot-pressing treatment on the blended yarns, flattening and compressing them to reduce gaps. Simultaneously, a hot-pressing spring rod drives a guide roller via a guide block, ensuring the hot-pressed blended yarns remain taut and reducing elastic deformation. However, the existing technology has the following problems.

[0004] After the blended yarn is wound up, it is necessary to remove the wound blended yarn and the winding drum from the drive equipment, replace it with a new winding drum, and then perform the next winding. This operation is cumbersome and reduces the efficiency of blended yarn preparation, which has certain shortcomings. In order to solve the above problems, a blended yarn preparation system and spinning process are proposed. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a blended yarn preparation system and spinning process, which allows the blended yarn to be quickly wound up through the remaining winding drum after one winding drum has finished winding, thereby improving preparation efficiency.

[0028] A spinning process for a blended yarn preparation system, using the aforementioned blended yarn preparation system, the method includes the following steps;

[0029] S1: The blended yarn is conveyed to the top of the machine body via the conveying roller, and the blended yarn passes through the cleaning mechanism and is wound up by the winding mechanism, so that the cleaning mechanism cleans the blended yarn during the conveying process.

[0030] S2: When the cleaning mechanism cleans the blended yarn, it uses airflow to generate suction, which drives the blended yarn, ensuring the contact area with the blended yarn, and collecting the cleaned short fibers and other impurities.

[0031] S3: When winding up the blended yarn after cleaning, the wound-up blended yarn does not need to be unwound before the next winding.

[0032] This invention provides a system for preparing blended yarns and a spinning process. Compared with the prior art, it has the following advantages:

[0033] 1. The present invention drives the fixed rod and the take-up drum to rotate through the driving mechanism of the winding mechanism, thereby facilitating the winding of the cleaned blended yarn. By setting the take-up drums in a ring array, after one take-up drum has finished winding, the remaining take-up drums can be used to quickly wind up the blended yarn, thereby improving the production efficiency.

[0034] 2. The present invention can drive the fixed rod and the take-up drum to rotate through the drive component to take up the blended yarn. It can also drive the fixed rod and the take-up drum to revolve around the center point of the rotating disk so that the unwound take-up drum is close to the shell, so as to facilitate the quick replacement of the take-up drum for the blended yarn, which is convenient for actual preparation and use.

[0035] 3. The present invention facilitates the removal of the fixing rod and the winding drum from the mounting base through the quick-release component, which makes it easy to replace the winding drum after winding when the remaining winding drum is winding, thus facilitating actual operation. Furthermore, the disassembly and assembly component makes it easy to remove the winding drum from the fixing rod, which is convenient for actual disassembly and assembly.

[0036] 4. This invention cleans the blended yarn while simultaneously conveying it through the rotation of the cleaning roller. At the same time, the suction generated by the air inlet of the suction fan causes the washed and moved blended yarn, increasing the contact area between the cleaning roller and the blended yarn and improving the cleaning effect. Furthermore, the short fibers and other impurities sucked up by the suction fan are discharged into the water tank through the air guide box and the first air guide pipe. After being filtered by the water in the water tank, they are discharged through the second air guide pipe, avoiding pollution of the working environment and facilitating practical use.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Example 1; please refer to Figure 1 A system for preparing blended yarn includes a machine body 1 placed on the ground, a cleaning mechanism 4 disposed on the top of the machine body 1 for cleaning the blended yarn, and a winding mechanism 5 disposed on the top of the machine body 1 for winding the blended yarn. The winding mechanism 5 is located on one side of the cleaning mechanism 4.

[0047] A mounting bracket 2 is fixedly provided on the top of the machine body 1 and on the side of the housing 41 away from the support base 55. A conveying roller 3 for conveying blended yarn is provided on the inner side of the mounting bracket 2.

[0048] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The winding mechanism 5 includes;

[0049] A support base 55 is fixedly mounted on the top of the body 1. A rotating disk 56 is rotatably mounted on the back of the support base 55. A quick-release assembly 52 arranged in a ring array is provided on the back of the rotating disk 56. A disassembly assembly 54 is provided on the side of the quick-release assembly 52 away from the rotating disk 56. A winding drum 53 is provided on the side wall of the disassembly assembly 54. A drive assembly 51 is provided on the front of the rotating disk 56. The drive assembly 51 includes:

[0050] The rotating shafts 514 are arranged in a ring array and rotate on the front of the rotating disk 56. One end of each rotating shaft 514 extends to the back of the rotating disk 56. The side wall of the rotating shaft 514 located on the front of the rotating disk 56 is fixedly fitted with a first gear 512. The front of the rotating disk 56 is rotatably provided with a gear ring 513 that meshes with the first gear 512, and the gear ring 513 is located outside the first gear 512.

[0051] Driver component 51 also includes;

[0052] The first servo motor 511 is fixedly mounted on the side wall of the rotating disk 56, and the output shaft of the first servo motor 511 is fixedly connected to one of the rotating shafts 514 through a coupling, for driving the rotating shaft 514 to rotate.

[0053] The second servo motor 515 is fixedly mounted on the outside of the support base 55. The output shaft of the second servo motor 515 is fixedly mounted with a rotating rod through a coupling. One end of the rotating rod away from the second servo motor 515 extends to the back of the support base 55, and the end of the rotating rod located on the back of the support base 55 is fixedly connected to the rotating disk 56.

[0054] In practice, when the cleaned blended yarn is wound up, the first servo motor 511 is started. The output shaft of the first servo motor 511 drives the rotating shaft 514 to rotate. The rotating shaft 514 drives one of the first gears 512 to rotate. The first gear 512 drives the gear ring 513 to rotate. Since the gear ring 513 and the first gear 512 are meshed, the remaining first gear 512 and the rotating shaft 514 rotate synchronously to wind up the cleaned blended yarn.

[0055] After one take-up drum 53 has finished winding, the operator cuts the blended yarn and winds it onto the outer wall of the remaining take-up drum 53. Then, the second servo motor 515 is started. The output shaft of the second servo motor 515 drives the rotating disk 56 to rotate through the coupling, thereby causing the take-up drum 53 to rotate around the center point of the rotating disk 56. This causes the remaining take-up drum 53 to rotate to the side closer to the housing 41, so as to facilitate the winding of the blended yarn.

[0056] The side wall of the rotating rod is rotatably connected to the front of the support base 55 to limit the rotation of the rotating rod and ensure the stability of the rotation of the rotating rod. The back of the support base 55 is provided with a groove for fitting the toothed ring 513 to provide space for the rotation of the toothed ring 513.

[0057] Please see Figure 4 and Figure 5 The quick-release component 52 includes;

[0058] Mounting base 521 is fixedly mounted on one end of rotating shaft 514 located on the back of rotating disk 56. A limiting seat 525 is fixedly mounted on the inner wall of the back of mounting base 521. A limiting groove is opened on the back of limiting seat 525. An electromagnet 526 is fixedly mounted on the inner wall of the back of limiting groove. A spring 524 is fixedly mounted on the inner wall of the back of mounting base 521 and on the outside of limiting seat 525.

[0059] The limiting block 523 is fitted into the limiting groove. A fixing plate 522 is fixed on the side of the limiting block 523 near the limiting seat 525. The fixing plate 522 is made of magnetic metal. The longitudinal section of the limiting block 523 is designed as a regular hexagon, and the side wall of the limiting block 523 is adapted to the inner wall of the limiting groove.

[0060] In practical implementation, when installing the take-up drum 53 and the fixing rod 541, the limiting block 523 is inserted into the limiting groove, so that the limiting block 523 is embedded in the limiting seat 525. Then, the electromagnet 526 is energized. Since the fixing plate 522 is made of magnetic metal material, the electromagnet 526 magnetically attracts the fixing plate 522 to fix the fixing plate 522 and the limiting block 523, thereby fixing the fixing rod 541 and the take-up drum 53. By making the longitudinal section of the limiting block 523 into a regular hexagonal design, the limiting block 523 is limited, ensuring the stability of the rotation of the fixing rod 541 and the limiting block 523 and avoiding the situation of free rotation.

[0061] When it is necessary to remove the fixing rod 541 and the winding drum 53 from the mounting base 521, the electromagnet 526 is de-energized, thereby canceling the magnetic attraction of the electromagnet 526 to the fixing plate 522. At this time, under the action of the spring 524, the spring 524 disengages the limiting block 523 from the limiting seat 525, thus realizing the quick removal of the fixing rod 541 and the winding drum 53.

[0062] Please see Figure 4 The disassembly and assembly components 54 include;

[0063] The fixing rod 541 is fixedly installed on the side of the limiting block 523 away from the limiting seat 525. The side wall of the fixing rod 541 is provided with a sliding groove arranged in an annular array, and the inner wall of the back of the sliding groove extends to the back of the fixing rod 541. The inner wall of the winding drum 53 is fixedly provided with a slider arranged in an annular array, and the sliders are placed in the sliding grooves respectively.

[0064] The disassembly and assembly component 54 also includes;

[0065] The screw 543 is fixedly disposed on the side of the fixing rod 541 away from the limiting block 523, and the side wall diameter of the screw 543 is smaller than the side wall diameter of the fixing rod 541.

[0066] Nut 542 is threaded to the side wall of screw 543. Nut 542 is an integral washer type nut 542, and the outer diameter of the washer is larger than the side wall diameter of the fixing rod 541, which is used to limit the winding drum 53.

[0067] In practice, loosen nut 542 and remove it. Then, pull the take-up drum 53 to move the slider along the slide groove, so that the slider separates from the slide groove. This allows the take-up drum 53 and the wound blended yarn to be removed for easy use.

[0068] Example 2, please refer to Figure 6 and Figure 7 The difference between this embodiment and embodiment two is that the cleaning mechanism 4 includes;

[0069] The housing 41 is fixedly installed on the top of the machine body 1, and both sides of the housing 41 are designed to be open. Both sides of the inner side of the housing 41 are provided with traction rollers 45 for conveying blended yarn. The upper inner side of the housing 41 is rotatably connected to vertically arranged cleaning rollers 42, and one end of the cleaning rollers 42 extends to the front of the housing 41. A second gear 43 that meshes with each other is fixedly sleeved on one side of the cleaning rollers 42 located on the front of the housing 41.

[0070] The third servo motor 44 is fixedly mounted on the front of the housing 41. The output shaft of the third servo motor 44 is fixedly connected to one of the cleaning rollers 42 through a coupling, and is used to drive the cleaning roller 42 to rotate.

[0071] Cleaning facility 4 also includes;

[0072] A suction fan 46 is fixedly installed on the bottom inner wall of the housing 41. The bottom inner wall of the housing 41 is provided with a mounting groove for installing the suction fan 46. The inner wall of the mounting groove is fixedly provided with an air guide box 47 connected to the exhaust end of the suction fan 46. The exhaust end of the air guide box 47 is fixedly provided with a first air guide pipe 48 extending to the outside of the machine body 1.

[0073] Water tank 491 is fixedly installed on the outside of the body 1. The exhaust end of the first air pipe 48 extends into the water tank 491 and is located below the water surface in the water tank 491. A second air pipe 49 extending to the top of the water tank 491 is fixedly installed on the inner wall of the top of the water tank 491. The air inlet end of the second air pipe 49 extends to the water surface in the water tank 491.

[0074] In practical implementation, when the blended yarn is cleaned by the cleaning roller 42, the third servo motor 44 is started. The output shaft of the third servo motor 44 drives one of the cleaning rollers 42 to rotate through the coupling. Due to the meshing of the second gear 43, the two cleaning rollers 42 rotate in opposite directions, thereby conveying and cleaning the blended yarn at the same time. At the same time, the suction fan 46 is started. The air inlet of the suction fan 46 generates suction, which washes and moves the blended yarn, increasing the contact area between the cleaning roller 42 and the blended yarn, improving the cleaning effect. The short fibers and other impurities sucked up by the suction fan 46 are discharged into the water tank 491 through the air guide box 47 and the first air guide pipe 48. After being filtered by the water in the water tank 491, they are discharged through the second air guide pipe 49, avoiding pollution of the working environment and facilitating practical use.

[0075] The third servo motor 44 and the like of the present invention are all connected to an external power supply and controller via wires for actual control. This is prior art and will not be described in detail here.

[0076] This invention also provides a spinning process for a blended yarn preparation system, which includes the following steps:

[0077] S1: The blended yarn is conveyed to the top of the machine body 1 via the conveying roller 3, and the blended yarn is conveyed by the traction roller 45 of the cleaning mechanism 4. While being conveyed by the traction roller 45, the blended yarn is cleaned by the cleaning roller 42 and wound up by the take-up drum 53 of the winding mechanism 5, so that the cleaning mechanism 4 cleans the blended yarn during the conveying process.

[0078] S2: When the cleaning mechanism 4 cleans the blended yarn, it generates suction through airflow to drive the blended yarn, ensuring the contact area with the blended yarn, thereby improving the cleaning effect of the cleaning roller 42. It also uses air suction to drive the blended yarn and discharges the sucked gas and impurities such as short fibers into the water tank 491 for filtration, thereby collecting the cleaned short fibers and other impurities.

[0079] S3: When the blended yarn is wound up after cleaning, the drive component 51 drives the quick-release component 52, the disassembly and assembly component 54 and the winding drum 53 to rotate, so that the blended yarn is wound on the winding drum 53. After one winding is completed, the second servo motor 515 drives the rotating disk 56 to rotate, which in turn drives the winding drum 53 to rotate around the center point of the rotating disk 56. The remaining winding drum 53 can then be used to wind up the cleaned blended yarn without having to unwind the wound blended yarn for the next winding, thus improving production efficiency.
