Description

Technical Field

[0001] This invention relates to the field of knitting equipment technology, specifically to a multi-head knitting processing device and process for wool yarn. Background Technology

[0002] In the production of wool products such as sweaters and scarves, it is often necessary to combine multiple strands of wool yarn and weave them into a thicker, more distinctive fancy yarn.

[0003] As described in patent application CN201810867898.0, a yarn weaving device includes a support plate, an electric turntable, a weaving cavity, a support rod, and a base. An absorption cover is located at the center of the top of the weaving cavity, and a motor is located at the center of the top of the support rod. A first connecting plate is located inside the weaving cavity on the side of the second connecting plate away from the support rod. First yarn spools are hinged to both ends of the first and second connecting plates. A weaving opening is located on the inner wall of the weaving cavity on the side of the first yarn spool away from the support rod. An electric turntable is located at the top of the base on the side of the base away from the weaving opening. A second yarn spool is mounted on the top of the electric turntable. A vacuum cleaner is located on one side of the power cavity, and a storage box is located inside the power cavity on the side of the vacuum cleaner.

[0004] In the above technical solutions, it is difficult to achieve synchronous and precise adjustment of the tension of each yarn strand, which can easily lead to uneven tension in the final woven yarn, affecting product quality. In addition, the operation of changing the yarn bobbin is relatively cumbersome, and poor fixation may lead to poor yarn feeding. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-head knitting processing device and process for wool yarn, which solves the problem that it is difficult to achieve synchronous and precise adjustment of the tension of each strand of yarn, which easily leads to uneven tension in the final knitted yarn and affects product quality; in addition, the operation of changing yarn bobbins is relatively cumbersome, and poor fixation may lead to problems with unsmooth yarn feeding.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-head knitting processing device for wool yarn, comprising a processing table, a reversing mechanism being provided on the upper surface of the processing table, a support and positioning component for positioning the yarn bobbin being provided on the upper surface of the reversing mechanism, a tensioning component for adjusting the tightness of the wool yarn being provided on the upper surface of the processing table, an installation rod being fixedly installed on the upper surface of the processing table, a top plate being fixedly installed on the top end of the installation rod, a servo motor being installed on one side surface of the top plate, and a take-up shaft being installed at the output end of the servo motor.

[0007] Preferably, a plurality of support rods are fixedly installed at equal intervals on the lower surface of the processing table, and a support ring is fixedly installed at the lower end of the plurality of support rods.

[0008] Preferably, a support plate is fixedly installed in the middle of the mounting rod, and side plates are fixedly installed on both sides of the support plate, with guide wheels installed between the two side plates.

[0009] Preferably, the support and positioning component includes a plurality of mounting blocks, which are fixedly mounted at equal intervals on the output end surface of the commutator.

[0010] Preferably, a support shaft is fixedly installed in the middle of the upper surface of each mounting block, a first through hole is installed on one side surface of the mounting block, a positioning plate is fixedly installed on one side upper surface of the mounting block, a limit shaft is rotatably installed between the inner walls on both sides of the upper end of the positioning plate, a swing plate is fixedly installed on one side surface of the limit shaft, a screw is installed on the swing plate through a screw sleeve, a pressure plate is installed at the lower end of the screw, and the pressure plate is located directly above the support shaft.

[0011] Preferably, the tensioning assembly includes a fixing rod, which is fixedly installed on the upper surface of the processing table. A support plate is installed on the upper end of the fixing rod. A plurality of sliding plates are equidistantly mounted on the circumference of the support plate. A second through hole is opened at one end of each sliding plate. A plurality of guide grooves are equidistantly opened on the upper surface of the support plate. A guide rod is slidably installed inside each guide groove. The lower end of the guide rod is connected to the sliding plate. A hydraulic cylinder is fixedly installed on the upper surface of the support plate. A top plate is installed at the output end of the hydraulic cylinder. A plurality of second limiting grooves are equidistantly opened on the surface of the top plate. A second rotating shaft is rotatably installed between the inner walls on both sides of the second limiting groove. A first limiting groove is opened on the upper surface of the guide rod. A first rotating shaft is rotatably installed between the inner walls on both sides of the first limiting groove. The first rotating shaft and the second rotating shaft are connected by a connecting rod.

[0012] A multi-head knitting process for wool yarn, the specific operation steps are as follows;

[0013] S1. Take multiple wool yarn bobbins and fit them onto the support shaft of each mounting block. For each yarn bobbin, rotate the corresponding screw downwards. The pressure plate at the lower end of the screw will then descend and press tightly against the top of the inner tube of the yarn bobbin, firmly fixing it to the support shaft to prevent it from rotating randomly during yarn feeding. Lead the yarn end out from each yarn bobbin and pass it through the first through hole on the side of the mounting block in sequence. This through hole serves as a preliminary bundling and guiding function.

[0014] S2. Pass all the yarns drawn from the reversing machine through the second perforation at the end of the corresponding slide plate on the tensioning assembly. Activate the hydraulic cylinder to push the top plate downward. The top plate pulls all the guide rods outward through the connecting rod. Since the lower end of the guide rod is connected to the slide plate and is restricted by the guide groove, this action causes all the slide plates to slide outward synchronously towards the support plate, thereby increasing the circumference diameter formed by all the second perforations. At this time, the yarn is tightened, and the initial tension setting is completed. During the entire weaving process, the tension can be finely adjusted at any time as needed through the hydraulic cylinder.

[0015] S3. All the yarns drawn from the tensioning assembly are passed around the guide wheel and finally evenly wound onto the take-up shaft;

[0016] S4. Start the reversing mechanism and let it rotate slowly. The rotation of the reversing mechanism will cause the entire support and positioning assembly and all the yarn bobbins on it to revolve together. The advantage of doing this is that the yarn bobbins constantly change positions during the unwinding process, making the twist of the multi-strand yarn more uniform, and at the same time effectively preventing the yarn from getting tangled together.

[0017] S5. Start the servo motor to drive the take-up shaft to rotate at the set speed and start winding the yarn. When the weaving task is completed or the take-up shaft is full, first stop the servo motor, then stop the reversing machine, remove the woven yarn roll from the take-up shaft, rotate the screw to raise the pressure plate, replace with a new wool yarn spool, and proceed with the next weaving operation.

[0018] This invention provides a device and process for multi-head knitting of wool yarn. It has the following beneficial effects:

[0019] 1. The support shaft is vertically fixed to the mounting block to hold the wool yarn bobbin. A positioning plate is fixed to one side of the mounting block, and a limiting shaft on it connects to a swing plate that can slightly oscillate around it. A threaded sleeve and a screw screwed into it are mounted on the swing plate, with a pressure plate at the end of the screw. When the yarn bobbin is inserted into the support shaft, tightening the screw causes the pressure plate to move downwards, firmly pressing the yarn bobbin. The support positioning assembly uses a screw-pressure plate structure, making the clamping and releasing of the yarn bobbin very quick, greatly reducing material change time and improving equipment utilization.

[0020] 2. Activate the hydraulic cylinder to push the top plate downwards. The top plate pulls all the guide rods outwards via the connecting rod. Since the lower end of the guide rod is connected to the sliding plate and is restricted by the guide groove, this action causes all the sliding plates to slide outwards synchronously towards the support plate, thereby increasing the circumference diameter formed by all the second perforations. At this time, the yarn is tightened, and the initial tension setting is completed. During the entire weaving process, the tension can be finely adjusted at any time as needed via the hydraulic cylinder. The hydraulic cylinder-driven linkage tensioning assembly allows for simultaneous adjustment of the tension of all yarns with a single action, ensuring uniform tension of each strand of yarn and greatly improving the final product quality of the woven yarn.

[0029] like Figure 1 As shown, a plurality of support rods 4 are fixedly installed at equal intervals on the lower surface of the processing table 1, and a support ring 5 is fixedly installed at the lower end of the plurality of support rods 4.

[0030] like Figure 1 As shown, a support plate 7 is fixedly installed in the middle of the mounting rod 6, and side plates 9 are fixedly installed on both sides of the support plate 7. A guide wheel 10 is installed between the two side plates 9.

[0031] like Figure 2 , 3 As shown in Figure 5, the support and positioning assembly 3 includes several mounting blocks 301, which are equidistantly fixedly mounted on the output end surface of the commutator 2. A support shaft 305 is fixedly mounted in the middle of the upper surface of each mounting block 301. A first through hole 309 is mounted on one side surface of each mounting block 301. A positioning plate 302 is fixedly mounted on one side upper surface of each mounting block 301. A limiting shaft 303 is rotatably mounted between the inner walls of both sides of the upper end of the positioning plate 302. A swing plate 304 is fixedly mounted on one side surface of the limiting shaft 303. A screw 307 is mounted on the swing plate 304 via a screw sleeve 306. A pressure plate 308 is mounted at the lower end of the screw 307. The pressure plate 308 is located directly above the support shaft 305. The support shaft 305 is vertically fixed to the mounting block 301 and is used to hold wool yarn bobbins. The positioning plate 302 is fixed to one side of the mounting block 301, and the limiting shaft 303 on it is connected to the swing plate 304, which can swing slightly around it. A threaded sleeve 306 and a screw 307 screwed into it are installed on the swing plate 304, and a pressure plate 308 is installed at the end of the screw 307. After the yarn bobbin is inserted into the support shaft 305, the screw 307 is tightened, the pressure plate 308 moves down, and firmly presses the yarn bobbin. After the yarn is drawn out from the yarn bobbin, it first passes through the first through hole 309 on the side of the mounting block 301 to increase the tension of the yarn.

[0032] like Figure 2 , 3As shown in Figure 4, the tensioning assembly 8 includes a fixing rod 801, which is fixedly installed on the upper surface of the processing table 1. A support plate 802 is installed on the upper end of the fixing rod 801. A plurality of sliding plates 803 are equidistantly mounted on the circumference of the support plate 802. A second through hole 804 is formed at one end of each sliding plate 803. A plurality of guide grooves 805 are equidistantly formed on the upper surface of the support plate 802. A guide rod 806 is slidably installed inside each guide groove 805. The lower end of the guide rod 806 is connected to the sliding plate 803. A hydraulic cylinder 813 is fixedly installed on the upper surface of the support plate 802. A top plate 810 is installed at the output end of the hydraulic cylinder 813.

All the yarns drawn from the reversing machine pass through the second perforations at the corresponding ends of the slide plates on the tensioning assembly. The hydraulic cylinder is activated, pushing the top plate downward. The top plate pulls all the guide rods outward through the connecting rod. Since the lower ends of the guide rods are connected to the slide plates and are restricted by the guide groove, this action causes all the slide plates to slide outward synchronously towards the support plate, thereby increasing the circumference diameter formed by all the second perforations. At this time, the yarn is tightened, and the initial tension setting is completed. During the entire weaving process, the tension can be finely adjusted at any time by the hydraulic cylinder as needed. The hydraulic cylinder-driven linkage tensioning assembly can adjust the tension of all yarns synchronously with one action, ensuring that the tension of each strand of yarn is uniform and consistent, which greatly improves the product quality of the final woven yarn.

[0033] A multi-head knitting process for wool yarn, the specific operation steps are as follows;

[0034] S1. Take multiple wool yarn bobbins and fit them onto the support shaft 305 of each mounting block 301. For each yarn bobbin, rotate the corresponding screw 307 downwards. The pressure plate 308 at the lower end of the screw will then descend and press tightly against the top of the inner tube of the yarn bobbin, fixing it firmly to the support shaft 305 to prevent it from rotating randomly during yarn feeding. Lead the yarn end out from each yarn bobbin and pass it through the first through hole 309 on the side of the mounting block 301 in sequence. This through hole plays a role in initial bundling and guiding.

[0035] S2. Pass all the yarns drawn from the commutator 2 through the second perforation 804 at the end of the corresponding slide plate 803 on the tensioning assembly 8. Start the hydraulic cylinder 813 to push the top plate 810 downward. The top plate 810 pulls all the guide rods 806 outward through the connecting rod 809. Since the lower end of the guide rod 806 is connected to the slide plate 803 and is restricted by the guide groove 805, this action causes all the slide plates 803 to slide outward synchronously towards the support plate 802, thereby increasing the circumference diameter formed by all the second perforations 804. At this time, the yarn is tightened and the initial tension setting is completed. During the entire weaving process, the tension can be finely adjusted at any time by the hydraulic cylinder as needed.

[0036] S3. All the yarns drawn from the tensioning assembly are passed around the guide wheel 10 and finally evenly wound onto the take-up shaft 13.

[0037] S4. Start the commutator 2 and let it rotate slowly. The rotation of the commutator will cause the entire support and positioning assembly 3 and all the yarn bobbins on it to revolve together. The advantage of doing this is that the yarn bobbins continuously change positions during the unwinding process, making the twist of the multi-strand yarn more uniform, and at the same time effectively preventing the yarn from tangling together.

[0038] S5. Start the servo motor 12 to drive the take-up shaft 13 to rotate at the set speed and start winding the yarn. When the weaving task is completed or the take-up shaft is full, first stop the servo motor, then stop the reversing machine, remove the woven yarn roll from the take-up shaft 13, rotate the screw 307 to raise the pressure plate 308, replace with a new wool yarn bobbin, and start the next weaving operation.

[0039] Working principle: The operator fixes six yarn bobbins onto the support and positioning assembly 3. The yarn is then passed through the first through hole 309, the corresponding second through hole 804, and then around the guide wheel 10 before finally being fixed to the take-up shaft 13. The stroke of the hydraulic cylinder 813 is adjusted to set the required yarn tension. Then, the commutator 2 and the servo motor 12 are started simultaneously. The commutator 2 drives all the yarn bobbins to rotate slowly, effectively preventing yarn tangling. The servo motor 12 drives the take-up shaft 13 to rotate at a constant speed, weaving the six evenly tensioned wool yarns into one and winding them up. The commutator 2 can be driven by a low-speed motor to achieve low-speed and stable rotation. The operator activates the hydraulic cylinder to push the top plate downward. The top plate pulls all the guide rods outward through the connecting rod. Since the lower end of the guide rod is connected to the slide plate and is restricted by the guide groove, this action causes all the slide plates to slide outward synchronously towards the support plate, thereby increasing the circumference diameter formed by all the second perforations. At this time, the yarn is tightened, and the initial tension setting is completed. During the entire weaving process, the tension can be finely adjusted at any time as needed by the hydraulic cylinder. The hydraulic cylinder-driven linkage tensioning component can adjust the tension of all the yarns synchronously with one action, ensuring that the tension of each yarn is uniform and consistent, which greatly improves the product quality of the final woven yarn.

[0040] It is obvious that the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
