Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of winding machines, in particular to a knitted fabric winding machine with self-adjusting preload force. Background Art
[0002] Knitted fabric is a fabric formed by using knitting needles to bend yarn into loops and intertwine them. It is divided into warp knitted fabric and weft knitted fabric. Winding machines are used in the receiving part of the coil processing production line to mechanically wind the raw materials into coils. They are widely used in paper rolls, cloth rolls, plastic rolls, and metal coil processing production lines.
[0003] In the existing technology, due to the strong ductility of knitted fabrics themselves, wrinkles and uneven tension are prone to occur. If the tension of the knitted fabrics is not adjusted during the winding process, the tension fluctuations will cause the fabric to be unevenly tight, locally overstretched or loosely accumulated, resulting in wrinkles on the surface of the knitted fabrics, fiber damage or even breakage, reducing production efficiency and product quality. Utility Model Content
[0004] The utility model discloses a knitted fabric winding machine with self-adjusting pre-tightening force, which aims to solve the technical problem that, due to the physical properties of the knitted fabric, the tightness of the fabric is uneven due to tension fluctuation during the winding process.
[0005] The cam is secured to the chassis and is adapted to move the rollers relative to the chassis, and the rollers are secured to the chassis at the chassis's rear end. Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.
[0006] By providing an adjustment module, the floating sleeve drives the connecting part to slide by overcoming the elastic action of spring 2, so that the floating sleeve is displaced to one side. At the same time, through the force between the floating sleeve and the knitted fabric, the connecting part drives the sliding part to slide by overcoming the elastic action of spring 1, so that the floating sleeve produces relative movement with the movable roller. The tension fluctuations are offset by the elastic action of spring 1 and spring 2, and the tension force in the knitted fabric conveying process can be dynamically adjusted. The synergistic action of the floating sleeve and the spring assembly forms a tension buffer, absorbs tension fluctuations, maintains a constant conveying stress state, ensures the stability of the fabric surface quality during the winding process, avoids damage to the fabric caused by pulling due to unstable tension, improves the use effect of the device, and when the knitted fabric is offset during the conveying process, the edge of the knitted fabric will contact the tapered part of the conical cylinder, and the knitted fabric will be automatically adjusted to the middle position through the guiding effect of the taper, ensuring that the knitted fabric remains in the center position.
[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.
[0008] By setting up a leveling module, the drive motor is started to rotate the winding wheel, and the winding rope is quickly relaxed. At this time, due to the loss of the traction force of the winding rope, spring four elastically recovers, pushing the sliding frame and the friction wheel to rise and contact the knitted fabric. At the same time, spring three elastically recovers and pulls the sliding seat along the sliding rod to the side away from the winding wheel. The friction wheels moving to both sides flatten the wrinkled and folded knitted fabric to eliminate wrinkle deformation.
[0009] From the above, it can be seen that the utility model provides a knitted fabric winding machine with self-adjusting preload force, which can dynamically adjust the tensioning force during the knitted fabric conveying process through the adjustment module. The synergistic effect of the floating sleeve and the spring assembly forms a tension buffer, absorbs tension fluctuations, and maintains a constant conveying stress state, thereby ensuring the stability of the fabric surface quality during the winding process, avoiding damage to the fabric caused by pulling due to unstable tension, and improving the use effect of the device.
