Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically a low-tension twisting device for multi-fiber polyester-cotton yarn. Background Technology

[0002] Multifiber polyester-cotton yarn is a textile raw material made of polyester fiber and cotton fiber blend. It has the abrasion resistance of polyester fiber and the breathability of cotton fiber. After being processed into rolls by a twisting device, it can be used in the field of garment production and processing.

[0003] A low-tension twisting device for multi-fiber blended yarns, with announcement number CN213739833U, is based on a base. A geared motor is fixed at the center of the top inner side of the base. A turntable is fixed to the base through a rod inserted into the output end of the geared motor, and the turntable is rotatably connected to the base. Fixed shafts are evenly fixed at the top of the turntable. Vertical plates are fixed on both sides of the top of the base. A dust removal mechanism is provided on the side of the vertical plates. A horizontal bar is fixed at the top inner side of the vertical plates, and a twisting ring is fixed at the center of the horizontal bar. The drive motor drives the movable shaft to rotate, causing the take-up roller to collect the yarn into a roll. After the take-up is completed, the take-up roller can be pushed, causing the hexagonal block on one side to drive the support plate and compress the spring. At this time, the hexagonal block on the other side falls out of the hexagonal groove, thereby removing the take-up roller for replacement, making the twisting device more practical.

[0004] The low-tension twisting device for multi-fiber blended yarn described above still has a problem. During the use of this twisting device, the unwinding loop on the fixed shaft is easily subjected to force and rotates during the unwinding process, causing the yarn to scatter and become difficult to organize, resulting in a reduction in the processing efficiency of the twisting device. Therefore, a low-tension twisting device for multi-fiber polyester-cotton yarn is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, in the process of using twisting devices on the market, the unwinding loop on the fixed shaft is easily subjected to force and rotates during the unwinding process, causing the yarn to scatter and become difficult to organize, resulting in a reduction in the processing efficiency of the twisting device. This utility model proposes a low-tension twisting device for multi-fiber polyester-cotton yarn.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The low tension twisting device for multi-fiber polyester-cotton yarn of this utility model includes a base plate, a twisting mechanism is provided on the top side of the base plate, a driving mechanism is provided on the side of the base plate, a finishing mechanism is provided at one end of the top side of the base plate, and a fixing plate is fixed on the top side of the base plate.

[0007] Preferably, the twisting mechanism includes a fixed plate, a servo motor fixed to the side of the fixed plate, a turntable fixed to the output end of the servo motor passing through the fixed plate, through holes evenly distributed on the surface of the turntable, straight plates symmetrically fixed on both sides of the through holes, a rubber protrusion fixed to one end of the inner side of the straight plate, a pay-off roller fastened to the inner side of the straight plate, a limiting groove formed at one end of the pay-off roller, an insert rod slidably inserted into the inner side of the straight plate, a limiting cap fixed to one end of the insert rod, a spring fixed between the limiting cap and the straight plate, the spring being fitted onto the insert rod, and one end of the insert rod inserted into the limiting groove. Through the structure of the insert rod and the rubber protrusion, the pay-off roller is fixed, preventing the yarn on the pay-off roller from scattering during the twisting process, thereby improving the processing efficiency of the twisting device.

[0008] Preferably, the driving mechanism includes a support plate, a tapered cylinder fixed to the top side of the support plate, the support plate being fixed at the center of the top side of the base plate, an mounting plate fixed to the side of the base plate, a first drive motor fixed to one end of the side of the mounting plate, a limit shaft fixed to the output end of the first drive motor passing through the mounting plate, a take-up roller slidably mounted on the limit shaft, and a controller fixed to the top inner side of the mounting plate.

[0011] 1. This utility model, through the structural design of a low-tension twisting device for multi-fiber polyester-cotton yarn, sets up a twisting mechanism, with the pay-off roller fastened to the inside of the straight plate. Under the action of the spring force, the insert rod is driven to pass through the inner side of the limiting groove, pushing the pay-off roller to make close contact with the rubber protrusion. The yarn passes through the through hole for twisting.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4As shown, a low-tension twisting device for multi-fiber polyester-cotton yarn includes a base plate 1, a twisting mechanism is provided on the top side of the base plate 1, a driving mechanism is provided on the side of the base plate 1, a finishing mechanism is provided at one end of the top side of the base plate 1, and a fixing plate 2 is fixed on the top side of the base plate 1.

[0022] Please see Figure 2 As shown, the twisting mechanism includes a fixed plate 2, a servo motor 3 fixed to the side of the fixed plate 2, a turntable 4 fixed to the output end of the servo motor 3 passing through the fixed plate 2, through holes 5 evenly distributed on the surface of the turntable 4, straight plates 6 symmetrically fixed on both sides of the through holes 5, a rubber protrusion 7 fixed to one end of the inner side of the straight plate 6, a pay-off roller 8 fastened to the inner side of the straight plate 6, a limiting groove 9 opened at one end of the pay-off roller 8, an insert rod 10 slidably inserted into the inner side of the straight plate 6, a limiting cap 11 fixed to one end of the insert rod 10, a spring 12 fixed between the limiting cap 11 and the straight plate 6, and the spring 12 being fitted onto the insert rod 10. One end of the rod 10 is inserted into the inner side of the limiting groove 9. During operation, when encountering the problem of easy scattering during the existing unwinding process, the structure of the twisting mechanism is used to pull the limiting cap 11 to pull out the rod 10. At this time, the unwinding roller 8 can be fastened to the inner side of the straight plate 6. Then, the limiting cap 11 is released, and under the action of the spring 12, the rod 10 is driven to be inserted into the inner side of the limiting groove 9. At the same time, the unwinding roller 8 is pushed to make close contact with the rubber protrusion 7. At this time, the servo motor 3 is controlled to drive the turntable 4 to rotate, so that the yarn passes through the through hole 5 for twisting. At this time, the unwinding roller 8 will not rotate due to inertia, thus preventing the yarn on its surface from scattering, so as to facilitate subsequent processing.

[0023] Please see Figure 3 As shown, the driving mechanism includes a support plate 13, a conical cylinder 14 fixed to the top side of the support plate 13, the support plate 13 fixed at the center of the top side of the base plate 1, an mounting plate 101 fixed to the side of the base plate 1, a first drive motor 15 fixed to one end of the side of the mounting plate 101, a limiting shaft 16 fixed to the output end of the first drive motor 15 passing through the mounting plate 101, a take-up roller 17 slidably mounted on the limiting shaft 16, and a controller 18 fixed to the top inner side of the mounting plate 101. During operation, when encountering the problem of inconvenient replacement of collected yarn, the structure of the driving mechanism allows the take-up roller 17 to be mounted on the limiting shaft 16, and the first drive motor 15 to drive the limiting shaft 16 to rotate. Since the limiting shaft 16 is a hexagonal prism structure, it can drive the take-up roller 17 to rotate and collect the yarn into a roll. After collection, the yarn is taken out from one end of the limiting shaft 16, thus completing the yarn twisting process. The structure is simple and easy to use.

[0024] Please see Figure 4As shown, the finishing mechanism includes a second drive motor 19, with a disc 20 fixed to the output end of the second drive motor 19. A bolt 21 is rotatably mounted on the top edge of the disc 20, and a limiting ring 22 is fitted on the bolt 21. The second drive motor 19 is fixed to the top side of the base plate 1, and the limiting ring 22 is slidably connected to the bolt 21. Connecting frames 23 are symmetrically fixed on both sides of the limiting ring 22, and the connecting frames 23 are fitted on the limiting shaft 16 and rotatably connected to the limiting shaft 16. During operation, when the yarn cannot be neatly wound up, causing it to easily knot and scatter, the finishing mechanism controls the second drive motor 19 to drive the disc 20 to rotate. With the cooperation of the bolt 21 and the limiting ring 22, the connecting frame 23 is driven to move back and forth. At this time, the connecting frame 23 can drive the inner winding roller 17 to move simultaneously, thereby neatly winding the yarn onto the winding roller 17, which facilitates subsequent processing.

[0025] Please see Figure 5 As shown, a brush 24 is fixed to one end of the inner side of the conical cylinder 14. During operation, when the yarn surface is prone to dust accumulation, the brush 24 removes the dust from its surface as the yarn is output through the inner side of the conical cylinder 14 during the twisting process. This prevents the accumulation of dust on the surface, which affects the quality of subsequent processing.

[0026] Working Principle: Multi-fiber polyester-cotton yarn is a textile raw material made from a blend of polyester and cotton fibers. It possesses the abrasion resistance of polyester fibers and the breathability of cotton fibers. After being processed into rolls by a twisting device, it can be used in the garment manufacturing industry. In the existing twisting device, the unwinding loop on the fixed shaft is prone to rotation during the unwinding process, causing the yarn to scatter and be difficult to manage, resulting in a decrease in the processing efficiency of the twisting device. To solve this problem, a twisting mechanism and a management mechanism are set up. Pulling the limit cap 11 pulls out the insertion rod 10. At this time, the unwinding roller 8 can be fastened to the inside of the straight plate 6. Then, the limit cap 11 is released, and under the action of the spring 12, the insertion rod 10 is driven to insert into the inside of the limit groove 9. At the same time, the unwinding roller 8 is pushed to make close contact with the rubber protrusion 7, so that the yarn passes through the through hole 5 for twisting. At this time, the unwinding roller 8 will not rotate due to inertia, thus preventing the yarn on its surface from scattering. The yarn passes through the inside of the conical cylinder 14, and one end of the yarn is fixed on the take-up roller 17. The take-up roller 17 is placed inside the connecting frame 23 and slidably mounted onto the limiting shaft 16. At this time, with the cooperation of the controller 18, the first drive motor 15 can be controlled to drive the limiting shaft 16 to rotate. Since the limiting shaft 16 is a hexagonal prism structure, it can drive the take-up roller 17 to rotate, thereby driving the yarn to one end inside the conical cylinder 14. At the same time, the servo motor 3 is controlled to drive the turntable 4 to rotate, performing twisting processing on the multi-strand yarn. Then, the second drive motor 19 is controlled to drive the disc 20 to rotate. With the cooperation of bolt 21 and limit ring 22, the connecting frame 23 is driven to move back and forth. At this time, the connecting frame 23 can drive the take-up roller 17 on its inner side to move at the same time, so that the yarn is neatly wound on the take-up roller 17. After the processing is completed, each motor can be turned off and the bolt 21 can be turned off. At this time, the connecting frame 23 and the take-up roller 17 can be pulled out from the limit shaft 16 to replace the take-up roller 17 for subsequent twisting processing. This solves the problem that the yarn is easy to fall off during the use of existing unwinding loops.
