Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment and relates to an anti-wrinkle mechanism for rolling up low-weight quartz cloth. Background Art

[0002] Low-weight quartz cloth is made of thousands of 4-5tex ultra-fine quartz fibers, which are arranged radially after sizing and axis-joining, and interwoven with weft yarns. At present, wrinkling during winding is still a pain point in the industry in quartz cloth weaving. High-end quartz cloth is usually thin, light, and has poor dimensional stability. Therefore, once the tension is unstable during the winding process, the cloth roll will easily become loose inside and too tight outside, resulting in the internal fabric being squeezed, horizontal and vertical wrinkles, and the product will become defective cloth. Tension control refers to the ability to permanently control the tension of the coil when it is transported on the equipment, and the force that can stretch or tighten objects against each other during winding can be changed in a specified manner.

[0003] The production of ultra-thin electronic cloth is difficult due to the thin diameter of quartz single yarn, high weaving density, many winding and unwinding times during weaving, thin fabric thickness, and surface modification. Tension control is of utmost importance. If the applied tension exceeds the normal range, the quartz cloth will be deformed, the fabric will be damaged, and there will be cloud spots, which will lead to a lot of losses, especially in the winding system, where the losses caused by the breakage of the coil are more serious. However, if the tension is insufficient, it will lead to stress differences between the layers of the roll, thus affecting the overall performance and reliability. For example, the inner layer is loosely wound, and the outer layer pressure is too high, exceeding the inner layer's bearing limit, causing core pulling and affecting the processing quality; unstable tension will cause the coil line speed to change and the coil tightness to be different, resulting in product strength loss.

[0004] In the prior art, the commonly used anti-wrinkle method for winding is the spreading roller. The roller body of the spreading roller is made of rubber, and left-handed and right-handed roller wires are integrally formed on its surface. Its working mode is to be in "constant contact" with the surface of the cloth, and continuously apply external support force to the cloth to avoid wrinkles. However, "constant contact" means that the left-handed and right-handed roller wires are always in a state of friction with the surface of the cloth. Even if there are no wrinkles on the cloth, this friction is always in an applied state, and damage to the cloth is inevitable, especially for low-weight quartz cloth. The presence of wear has a negative impact on the weaving morphology and bundle performance of the filament fibers. At the same time, it also aggravates the deviation of the cloth during traction, because when there are wrinkles in the cloth, there is a difference in the tension applied by the left-handed and right-handed roller wires on both sides of the cloth, which aggravates the deviation.

[0005] The present invention applies the spreading roller to the winding mechanism of the air jet loom in a "normally separated" manner, aiming to effectively reduce the wrinkles of the rolled cloth surface, reduce the wear of the cloth, and improve the rolling quality of the quartz cloth. Summary of the invention

[0006] The purpose of the present invention is to provide an anti-wrinkle mechanism for rolling up low-weight quartz cloth in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the present invention is how to reduce the wear of the cloth during its spreading process.

[0007] The object of the present invention can be achieved through the following technical solutions: an anti-wrinkle mechanism for rolling up low-weight quartz cloth, the anti-wrinkle mechanism is displaced between two traction rollers on the traction path of the quartz cloth, and is characterized in that the anti-wrinkle mechanism comprises two suspension arms, two linkage arms, a trigger roller located below the cloth and two spreading rollers located above the cloth, the upper ends of the two suspension arms are hinged on the frame, the two spreading rollers are rotatably connected to the lower ends of the two suspension arms respectively, the lower ends of the two linkage arms are hinged to each other, the trigger roller is rotatably connected to the hinge point at the lower ends of the two linkage arms, the upper ends of the two connecting arms are respectively hinged to the middle parts of the two suspension arms, and a tension spring is connected between the middle parts of the two suspension arms; under normal conditions, there is an acute angle between the two suspension arms, and the cloth and the trigger roller are in a constant contact state; the two spreading rollers can contact the upper surface of the cloth when the trigger roller receives downward pressure.

[0008] Furthermore, the flat cloth is in a straight state between the two traction rollers and the trigger roller.

[0009] Two booms and two linkage arms form a quadrilateral linkage mechanism. When the fabric is in a tensioned state, if there are lateral wrinkles on the fabric, it will exert downward pressure on the trigger roller. At this time, the tension spring is compressed, and the distance between the two spreading rollers and the upper surface of the fabric is shortened to contact. The bidirectional roller wires on the surface of the spreading rollers will drive the fabric to unfold to eliminate wrinkles. On the contrary, when there are no wrinkles on the fabric, the spreading rollers and the fabric are in a separated state, and the fabric is not rubbed by the roller wires on the spreading rollers. This can greatly reduce the wear of the fabric caused by spreading, and also reduce the pressure of fabric deviation. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 and Figure 2As shown, the wrinkle-proof mechanism is displaced between two traction rollers 6 on the traction path of the quartz cloth. The wrinkle-proof mechanism includes two suspension arms 1, two linkage arms 2, a trigger roller 3 located below the cloth and two spreading rollers 4 located above the cloth. The upper ends of the two suspension arms 1 are hinged on the frame, the two spreading rollers 4 are rotatably connected to the lower ends of the two suspension arms 1, the lower ends of the two linkage arms 2 are hinged to each other, the trigger roller 3 is rotatably connected to the hinge point at the lower ends of the two linkage arms 2, the upper ends of the two connecting arms are respectively hinged to the middle parts of the two suspension arms 1, and a tension spring 5 is connected between the middle parts of the two suspension arms 1; under normal conditions, there is an acute angle between the two suspension arms 1, and the cloth is in a constant contact state with the trigger roller 3; the two spreading rollers 4 can contact the upper surface of the cloth when the trigger roller 3 receives downward pressure. The flat cloth is in a straight state between the two traction rollers 6 and the trigger roller 3.

[0015] The two booms 1 and the two linkage arms 2 form a quadrilateral linkage mechanism. When the fabric is in a tensioned state, if there are lateral wrinkles on the fabric, it will exert downward pressure on the trigger roller 3. At this time, the tension spring 5 is compressed, and the distance between the two spreading rollers 4 and the upper surface of the fabric is shortened to contact. The bidirectional roller wires on the surface of the spreading rollers 4 will drive the fabric to unfold to eliminate the wrinkles. On the contrary, when there are no wrinkles on the fabric, the spreading rollers 4 and the fabric are in a separated state, and the fabric is not rubbed by the roller wires on the spreading rollers 4. This can greatly reduce the wear of the fabric caused by spreading, and also reduce the pressure of fabric deviation.

[0016] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
