Description

[0002] With the development of the textile industry, the demand for fabric production continues to increase, and the market demand for fabrics is becoming increasingly diversified. Enterprises need to improve production efficiency to meet market demand. Efficient unwinding equipment can reduce the time for changing fabric rolls and equipment adjustment time, and achieve continuous and stable unwinding operations, thereby improving the production efficiency of the entire production line.
[0003] During the unwinding process of traditional unwinding equipment, the diameter of the cloth roll will gradually become smaller, resulting in a gradual decrease in tension, making the tension change uneven throughout the unwinding process. It is easy for the cloth to become loose and wrinkled in the later stage of unwinding, affecting the quality of subsequent processes. The design of the unwinding equipment is relatively fixed, and it will be damaged due to wear after long-term use. It is not conducive to disassembly and replacement of the roller. The remaining threads between the cloth during unwinding affect subsequent processing. Therefore, we propose an unwinding equipment for the production of pure cotton woven grey fabrics.

[0023] In this embodiment, the expansion structure 2 includes two groups of first fixed plates 21 fixedly connected to the workbench 1, and the adjacent side of the two groups of first fixed plates 21 is rotatably connected to the first roller 22, and the outer side of the first roller 22 is fixedly connected to two groups of side retaining rings 23, and the adjacent ends of the two groups of side retaining rings 23 are each installed with two groups of telescopic rods 24, and a group of output shafts adjacent to the two groups of telescopic rods 24 are commonly fixedly connected to a force ring 25, and the inner side of the force ring 25 is slidably connected to the first roller 22, and the other side of the force ring 25 is fixedly connected to the first three-leaf cylinder 26, and the inner side of the first three-leaf cylinder 26 is slidably connected to the first roller 22.
[0024] Specifically, in the later stage of unwinding, the diameter of the cloth roll gradually becomes smaller, resulting in a gradual decrease in tension, which makes the tension change uneven during the entire unwinding process and causes the cloth to slack. At this time, the two sets of telescopic rods 24 installed on one side of the two sets of side retaining rings 23 can be extended and retracted, and the output shaft thereof drives the force ring 25 to slide on the outside of the first roller 22, and the force ring 25 drives the first three-leaf cylinder 26 on one side to slide on the outside of the first roller 22.
[0025] The outer side of the first three-leaf cylinder 26 is rotatably connected with three groups of first connecting rods 27 through pivots, one end of the first connecting rod 27 is rotatably connected with a second connecting rod 28 through a pivot, and the three groups of second connecting rods 28 are rotatably connected with a second three-leaf cylinder 29 through pivots, and the inner side of the second three-leaf cylinder 29 is fixedly connected with the first roller 22.
[0026] Specifically, the first three-leaf cylinder 26 drives the three groups of first connecting rods 27 to rotate, one end of the first connecting rod 27 drives the second connecting rod 28 to rotate through a pivot, and the other end of the second connecting rod 28 is fixed by the second three-leaf cylinder 29.
[0027] In this embodiment, the outer side of the second three-leaf cylinder 29 is fixedly connected with three groups of connecting plates 210, one side of the connecting plate 210 is provided with a spring 211, one end of the spring 211 is fixedly connected with the connecting plate 210, and the other end of the connecting plate 210 is fixedly connected with the second connecting rod 28.
[0028] Specifically, the spring 211 fixed by the connecting plate 210 arranged on the outer side of the second three-leaf cylinder 29 can make one end of the first connecting rod 27 always slide outward and expand when the first three-leaf cylinder 26 slides, thereby reducing the failure rate.
[0029] In this embodiment, one side of the first connecting rod 27 is rotatably connected with a fixed block 212 through a pivot, one end of the two groups of fixed blocks 212 close to each other on the same side is fixedly connected with an arc-shaped plate 213, both ends of the arc-shaped plate 213 are fixedly connected with arc-shaped blocks 214, one side of the arc-shaped block 214 is installed with a roller 215, and the outer side of the roller 215 is slidably connected with the side stop ring 23.
[0030] Specifically, one side of one end of the first connecting rod 27 is rotatably connected with a fixed block 212, one end of the first connecting rod 27 drives the fixed block 212 on the same side to rotate when it expands outward, the fixed block 212 on the same side drives the arc-shaped plate 213 connected therewith to expand, a sliding groove is formed on one side of the two groups of side stop rings 23 close to each other, the arc-shaped block 214 connected at both ends of the arc-shaped plate 213 drives the roller 215 to slide in the sliding groove, and the simultaneous expansion of the three groups of arc-shaped plates 213 expands the diameter of the cloth roll.
[0031] In this embodiment, the outer side of the first gear 4 is rotatably connected with a second chain 8, the inner side of the second chain 8 is rotatably connected with a third gear 9, and one end of the third gear 9 is fixedly connected with the first roller 22.
[0032] Specifically, the motor 5 drives the first gear 4 to rotate, the first gear 4 drives the third gear 9 to rotate through the second chain 8, and the third gear 9 further drives the first roller 22 to rotate.
[0033] Working principle: When the equipment is in use, the outer sides of the three groups of curved plates 213 are used to evenly wrap the cloth, and one end of the cloth roll is passed through the outer side of the third roller 33 near the lower end, and then the cloth is passed through the roller fixed by one end of the second gear 7 and the subsequent groups of rollers. After completion, the motor 5 is driven to operate, and the operation of the motor 5 drives the first gear 4 to rotate. The first gear 4 drives the third gear 9 to rotate through the second chain 8, and the third gear 9 further drives the first roller 22 to rotate. The rotation of the first roller 22 drives the three groups of curved plates 213 to rotate. At the same time, the first gear 4 drives the second gear 7 to rotate through the first chain 6, and the second gear 7 drives the second gear 7 to rotate. The wheel 7 drives the roller shaft fixed to it to rotate to unwind the cloth. The excess thread attached to the cloth during unwinding drives the second roller 32 to rotate through the first gear 4. The second roller 32 generates static electricity due to the electromagnetic attached to the outside. The static electricity attaches the excess thread to the outside of the second roller 32 through the recovery groove on the outside of the third roller 33, thereby removing the excess thread during unwinding. When unwinding to the later stage, the diameter of the cloth roll gradually becomes smaller, resulting in a gradual decrease in tension, which makes the tension change unevenly during the entire unwinding process, causing the cloth to slack. At this time, the two sets of telescopic rods 24 installed on one side of the two sets of side retaining rings 23 can be extended and retracted, and the output shaft thereof drives the force circle 25 to rotate. The outside of the first roller 22 slides, and the force ring 25 drives the first three-leaf cylinder 26 on one side to slide on the outside of the first roller 22. The sliding of the first three-leaf cylinder 26 drives the three groups of first connecting rods 27 to rotate. One end of the first connecting rod 27 drives the second connecting rod 28 to rotate through the rotating shaft. The other end of the second connecting rod 28 is fixed by the second three-leaf cylinder 29. The spring 211 fixed by the connecting plate 210 provided on the outside of the second three-leaf cylinder 29 can make one end of the first connecting rod 27 always slide and expand outward when the first three-leaf cylinder 26 slides, thereby reducing the failure rate. A fixed block 212 is rotated on one side of one end of the first connecting rod 27. When one end of the connecting rod 27 expands outward, it drives the fixed block 212 on the same side to rotate, and the fixed block 212 on the same side drives the commonly connected arc plate 213 to expand. A sliding groove is provided on the side where the two sets of side retaining rings 23 are close to each other. The arc blocks 214 connected at both ends of the arc plate 213 drive the roller 215 to slide in the sliding groove. The three sets of arc plates 213 expand at the same time to expand the diameter of the cloth roll, preventing the tension from reducing and the cloth from becoming loose and wrinkled, thereby improving the quality of unwinding. Irreversible damage will occur when this equipment is used for a long time. The equipment can be repaired by removing the fixed block 212 and replacing the arc plate 213, thereby improving the practicality of the equipment.
[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
