Description

Technical Field

[0001] The utility model relates to the technical field of textile production, in particular to a filament bobbin returning device for a doubling machine. Background Art

[0002] In existing technology, the SSM doubling machine combines two or three yarn bobbins into a single bobbin of a certain length. The core of the doubling machine is a straight plastic tube with a small outer diameter (Ø40mm, 180mm long). The diameter of the doubling bobbin cannot be too large, and the length cannot be too long. Depending on the yarn count, the doubling length is generally set at around 20,000 meters. The two or three strands of yarn that have been doubling are then processed into twisted yarn on a two-for-one twister. Therefore, existing SSM doubling machines are only used for doubling yarn and cannot be used for rewinding filament yarn or converting large filament packages into smaller ones.

[0003] Textile companies are affected by order production. In the production process of core-wrapped yarn on spinning machines, raw materials such as 40-denier nylon filament are mostly large-package filament. Although large-package filament has a long production time on the machine, it can reduce the time of changing the filament bobbins and improve production efficiency. However, when the filament is unwound and replaced with a new filament bobbin, due to the different unwinding tensions of the spindles, the 840 filament bobbins configured on a spinning machine will not be unwound cleanly at the same time. There will always be a considerable number of filament bobbins with different lengths of filament remaining on them, ranging from a few thousand meters to tens of thousands of meters. If some small filament bobbins are hung for reuse, it will increase the time of frequent bobbin changes, affecting the production rhythm. In addition, for some core-spun yarn varieties that are sampled, when the purchased filament packages are too large, they cannot be hung on the spinning machine due to their large appearance. The only option is to convert the oversized filament bobbins into small filament bobbins of specified length for production on the machine. However, many spinning manufacturers do not have the ability (lack of special equipment, etc.) to convert large filament bobbins into small filament bobbins. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of the invention of the utility model is to provide a filament return device for a winding machine, which can re-lengthen the remaining filaments of the small-package filament bobbins replaced by the spinning frame and return them to a large-package filament bobbin of a specified length, or shorten the return bobbin of an oversized package filament bobbin to a filament bobbin that meets the package length to meet production needs.

[0005] To achieve the above-mentioned purpose, the utility model provides a filament return device for a doubling machine, comprising a frame, a right transmission swing arm, a left transmission swing arm, a yarn pressing roller, a yarn tube core, a tension rod, a stroke controller, a yarn passing channel, and a filament cake;

[0006] A left transmission swing arm and a right transmission swing arm are fixedly installed in the length direction of the frame, a left top plate is provided on the left transmission swing arm, and a right top plate is provided on the right transmission swing arm, and the surface of the yarn tube core located between the left top plate and the right top plate is in close contact with the yarn pressing roller; a transmission motor is also fixedly provided on the right transmission swing arm, and the transmission motor drives the right top plate to rotate and drives the yarn tube core to rotate synchronously via a transmission belt; the nylon filaments on the filament cake are wound on the yarn tube core in sequence through a yarn tension hook, a yarn passing channel, and a tension rod;

[0007] The tension rod is provided with a stroke controller for controlling the left and right strokes of the nylon filaments.

[0008] Furthermore, the left top plate is connected to the left transmission swing arm via a bearing and a pin shaft, and the right top plate is connected to the right transmission swing arm via a bearing and a pin shaft. The left top plate and the right top plate are made of aluminum alloy.

[0009] Furthermore, the left top disc and the right top disc are of the same size and are symmetrically arranged on both sides, and the yarn tube core is a parallel bobbin.

[0010] Furthermore, a knotter for filament joints is provided between the filament cake and the yarn tension hook.

[0011] Furthermore, both ends of the pressing roller are connected to a holder fixed on the frame, and a surface of the pressing roller is provided with grooves for controlling the reciprocating movement of the nylon filaments.

[0012] Furthermore, a waist-shaped hole is provided at the connection between the frame and the right transmission swing arm.

[0013] Furthermore, the wire passing channel includes a special-shaped tension bowl and a short mercerizing appliance, and the short mercerizing appliance is connected to the long wire fixed length control key of the loom.

[0014] Compared with the existing technology, the utility model improves the shape, material and size of the left and right top plates of the yarn tube, overcomes the problem that the existing small plastic tube core (outer diameter 40mm) has a small aperture and cannot be hung on the spinning frame, and breaks the disadvantage that the winding machine can only be used to combine yarns but cannot be used for filament return bobbins; the winding machine is used to re-lengthen the remaining yarn of the small-packaged filament bobbins into large-packaged filament bobbins of specified length, and the returned bobbins of purchased oversized packaged filament bobbins can also be shortened to filament bobbins that meet the winding process length, which is convenient for use in the spinning process or other processes, thereby retaining the original winding function of the winding machine, and increasing the return function, thereby improving the equipment utilization rate.

DETAILED DESCRIPTION

[0021] In order to make the invention purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail with reference to the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model and are not intended to limit the scope of protection of the utility model.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the utility model mainly includes a frame 13, a right transmission swing arm 1, a left swing arm 2, a yarn pressing roller 5, a yarn tube core 6, a tension rod 7, a stroke controller 8, a yarn passing channel 9, and a filament cake 12;

[0023] A left transmission swing arm 2 and a right transmission swing arm 1 are fixedly mounted along the length of the frame 13. A left top plate 4 is mounted on the left transmission swing arm 2, and a right top plate 3 is mounted on the right transmission swing arm 1. The surface of the bobbin core 6 located between the left and right top plates 4 and 3 is in close contact with a yarn pressing roller 5. A transmission motor 14 is also fixedly mounted on the right transmission swing arm 1. This motor 14 drives the right top plate 3 and the bobbin core 6 to rotate synchronously via a transmission belt 15. The transmission motor 14 is a permanent magnet micro-servo motor with a small size, light weight, high power factor, and high operating efficiency, which can meet the rotation requirements of the right top plate 3. The nylon filaments 10 on the filament cake 12 are sequentially wound onto the bobbin core 6 via a yarn tension hook 11, a yarn passage 9, and a tension rod 7.

[0024] The tension rod 7 is provided with a stroke controller 8 for controlling the left and right stroke of the nylon filament 10. The stroke controller 8 moves left and right with the tension rod 7 to control the width of the yarn cake wound on the yarn tube core 6. The stroke controller 8 is a conventional open-type small porcelain eyelet. The nylon filament 10 passes through the open-type small porcelain eyelet. While ensuring the left and right stroke of the nylon filament 10, it can avoid yarn and thread hanging, ensuring that the strength of the nylon filament remains unchanged.

[0025] Preferably, the left top plate 4 is connected to the left transmission swing arm 2 via a bearing 18 and a pin 17, and the right top plate 3 is connected to the right transmission swing arm 1 via a bearing 18 and a pin 17. The left top plate 4 and the right top plate 3 are made of aluminum alloy, which can bear the greater winding pressure of the yarn tube core 6 and have good dynamic balance. The bearings 18 and the pin 17 are arranged on the left and right sides, and the bearing 18 is installed on one end of the pin 17; one end of the pin 17 is connected to the left top plate 4 and the right top plate 3 respectively via the bearing 18, and the other end of the pin 17 is fixedly connected to the left transmission swing arm 2 and the right transmission swing arm 1 respectively. The bearing 18 is a double-sealed, oil-free 6001 deep groove ball bearing, which can effectively ensure the flexible rotation of the left top plate 4 and the right top plate 3 and is maintenance-free.

[0026] Preferably, the left and right top plates 4 and 3 are of identical size and symmetrically arranged. They are used in conjunction with a bobbin core 6, which is a parallel bobbin. The dimensions of the bobbin core 6 are: inner diameter × outer diameter × height: φ120mm × φ138mm × 128mm. The bobbin core 6 with an inner diameter of φ120mm ensures that the re-bobbed filament cakes can be used on the spinning frame (small plastic tube cores with an outer diameter of 40mm in the prior art cannot be suspended on the spinning frame due to their small aperture). The outer diameters of the left and right top plates 4 and 3 can be adaptively adjusted according to the diameter of the bobbin core 6 to meet the needs of a wider range of re-bobbed varieties.

[0027] Preferably, a knotter 16 for filament joints is provided between the filament cake 12 and the yarn tension hook 11. The knotter 16 is a purchased chemical fiber special knotting gun made of stainless steel or aluminum to avoid hanging wire, and the joint effect is excellent, meeting the joint quality requirements.

[0028] Preferably, both ends of the pressing roller 5 are connected to a U-shaped holder fixed on the frame 13, and a groove for controlling the reciprocating movement of the nylon filament 10 is provided on the surface of the pressing roller 5. The nylon filament 10 on the yarn tube core 6 is well formed under the extrusion of the pressing roller 5, and the yarn is tightly wound; the bobbin yarn is more meticulously formed after being returned to the bobbin, and the tension is uniform and has no fluctuation when it is unwound for use in the next process.

[0029] Preferably, a waist-shaped hole is provided at the connection between the frame 13 and the right transmission swing arm 1, and the right transmission swing arm 1 can be moved left and right on the frame 13 to meet the needs of yarn tube cores 6 of different lengths and adapt to more product specifications.

[0030] Preferably, the yarn passage 9 includes a special-shaped tension bowl and a short mercerizing device. The special-shaped tension bowl can control the tension of the nylon filament 10 during unwinding. The short mercerizing device is connected to the filament fixed length control key on the head of the machine and controls the length of the returned filament. The yarn passage 9 is a purchased part.

[0031] When the utility model is used, the filament cake 12 that needs to be re-reeled is placed under the frame 13, and the nylon filaments 10 on the filament cake 12 are wound on the yarn tube core 6 in sequence through the yarn tension hook 11, the wire channel 9, and the tension rod 7. The knotter 16 can be used to connect the broken ends to ensure that the filaments are complete. The left top plate 4 and the right top plate 3 made of aluminum alloy can withstand the restraining pressure of the nylon filaments 10 on the yarn tube core 6, ensuring that the filament tube is well formed after re-reeling. The present application can connect the remaining filaments of the N small-packaged filament tubes rotated off the spinning frame one by one in sequence, and re-reel into a large-packaged filament tube of a specified length, thereby achieving the purpose of returning the remaining filaments of the nylon filaments after connecting them, making it convenient for the spinning process to be reused again to reduce the waste of filaments. The purchased super-large filament bobbins can also be shortened (the super-large filament bobbins cannot be hung on the spinning machine frame due to their large size). The winding length can generally reach about 50,000 meters and be shortened to a filament bobbin that meets the process length, meeting the conversion from super-large bobbins to process packages, which is convenient for use in spinning or other processes.
