Description

Technical Field

[0001] The utility model belongs to the technical field of knitted fabric rolling and loose prevention, and particularly relates to a knitted fabric rolling device that prevents loosening. Background Art

[0002] During the knitted fabric production process, steps such as scouring, dyeing, and washing all affect the fabric's dimensional stability and density. Improper control of the tensile tension applied to the fabric during these processes can lead to fabric sag during subsequent processing and winding. While continuous production can improve efficiency, controlling the tensile tension presents significant challenges. In contrast, intermittent production can better achieve fabric relaxation, thereby maintaining dimensional stability and density. However, intermittent production also suffers from lower production efficiency. To address this sag during the winding process, a series of anti-loosening technologies are required. During the winding process, knitted fabrics experience increased weight and diameter as the winding time increases, causing them to jitter as they roll. This jitter is caused by factors such as the weight, diameter, softness, and winding speed of the roll, and can lead to varying degrees of looseness after winding. Utility Model Content

The device has a simple structure and is convenient and practical. The fabric is pre-stretched through a roll-changing auxiliary device to avoid the phenomenon that the fabric is wrinkled due to lack of winding force when the machine is stopped to change the winding core, resulting in the need to correct the creases when the fabric is rolled up again.

One end of the two sliding columns 23 is hinged on the fixed frame 1 and the other end is hinged to the compacting adjustment cylinder 25. The piston rod of the tightening adjustment cylinder 25 is hinged on the fixed frame 1, and the two follow-up winding devices 24 are respectively slidably connected to the sliding column 23. One end of the lifting cylinder is hinged on the sliding column 23 and the piston rod is hinged on the follow-up winding device 24; the follow-up winding device 24 includes a C-type slide 26, a fixed roller bearing 27, a clamping cylinder 28, a V-frame 29, a movable roller bearing 210 and a damper 211. The two fixed roller bearings 27 are symmetrically installed on one end of the C-type slide 26, the clamping cylinder 28 is installed on the other end of the C-type slide 26 and the piston rod is hinged to the middle of the V-frame 29, the two movable roller bearings 210 are respectively connected to the two ends of the V-frame 29, and the damper 211 is installed on one end of the C-type slide 26 and Cooperate with the fixed roller bearing 27; a roll changing auxiliary device 3 is installed on the fixed frame 1, and the roll changing auxiliary device 3 includes an adjusting cylinder 31, a rotating frame 32, a connecting shaft 33, a fixed traction roller 34 and a rotating traction roller 35.

[0021] The core is pre-installed on the tight winding device 2. Then the woven fabric is passed through several traction rollers 42, the coil releasing and traction group 43, the positive and negative thread rollers 44, the roll-changing auxiliary device 3 and the positive and negative thread roller group 45 and wound by the core. The power device drives two power rollers to provide a certain conveying force to convey the woven fabric. Specifically, when the woven fabric passes through the positive and negative thread rollers 44, the driving force generated by the rotation of the positive and negative threads makes the woven fabric flat, avoiding concave and convex patterns in the middle of the woven fabric. By arranging the positive and negative thread rollers 44 in a triangular shape, while making the woven fabric flat, a leveling pulling force is provided to prevent the concave and convex patterns of the woven fabric from recovering after being leveled. When changing the core, the adjusting oil cylinder 31 drives the rotating frame 32 to rotate, so that several fixed traction rollers 34 and the rotating traction roller 35 stagger and move away from each other, achieving the purpose of extending the conveying distance of the woven fabric through the staggered fixed traction rollers 34 and the rotating traction roller 35. The pressing oil cylinder 28 drives the V-shaped frame 29 to descend, and the moving roller bearing 210 on the V-shaped frame 29 descends, so that the core rolls between the two moving roller bearings 210 and the two fixed roller bearings 27. Then, the lifting oil cylinder drives the follower winding device 24 to descend to complete the lifting of both ends of the core. At the same time, the tightening adjusting oil cylinder 25 drives one end of the sliding column 23 to move, so that the core leans against the right winding roller 21 or the left winding roller 22 and contacts them. The power device controls the rotation speeds of the right winding roller 21 and the left winding roller 22 to be the same or one fast and one slow. When controlling the rotation speeds of the right winding roller 21 and the left winding roller 22 to be different, the winding speed of the core can be controlled to switch between fast and slow, achieving the purpose of the roll-changing auxiliary device 3 extending the woven fabric during winding and roll-changing. The function of the support bearing 41 is to release the rolled fabric for use. The rolled fabric is the rolled fabric pre-rolled and transported from the previous process, and it is suitable for intermittent production. The arc transition plate 5 is suitable for continuous production. The woven fabric processed in the previous process will be stacked on the arc transition plate 5 for winding. Pre-stacking the woven fabric on the arc transition plate 5 can reduce the tension generated during the conveying process of the woven fabric. The roll-changing auxiliary device 3 is generally used in continuous production, mainly to reduce the excessive length of the woven fabric stacked on the arc transition plate 5, resulting in the accumulation of the woven fabric.
