Description

Technical Field

[0001] This invention relates to the field of new technology in spinning, and in particular to a fiber uniform winding control system. Background Technology

[0002] In recent years, the traditional spinning industry has undergone profound changes, most notably in terms of significant progress in equipment automation, continuous operation, intelligence, high speed and efficiency, and low energy consumption, which has also promoted the shift towards higher quality and more diversified products. Automated spinning equipment is being widely used, and the pace of "machine replacing human labor" is accelerating. Adopting continuous spinning technology to shorten traditional spinning processes is also an important way to achieve "machine replacing human labor" and reduce labor costs. The adoption of intelligent technology is driving traditional spinning production towards online automatic monitoring. With the development of science and technology, especially the promotion and application of intelligent technology and the advancement of key spinning equipment manufacturing technology, favorable conditions have been created for high-speed operation of spinning equipment.

[0003] Sliver is one of the most important semi-finished products in the spinning process, involving three major steps: carding, combing, and drawing. During production, the sliver needs to be wound orderly within a sliver can of a certain diameter. In the traditional winding process, the winding mechanism, the winding disc, and the sliver can rotate in tandem. This coordinated rotation causes the sliver to wind continuously within the can in a specific elliptical structure, with the fibers not completely overlapping. This winding method creates air pockets in the center of the sliver can, with the densest overlap of fibers occurring at the edges of these air pockets, forming the densest density points. This uneven distribution of fibers within the can significantly limits the can's capacity to hold the sliver. Summary of the Invention

[0004] The purpose of this invention is to provide a fiber uniform winding control system. By setting independent lateral movement and axial rotation transmission mechanisms on the chassis where the sliver can is placed, independent, stable, and structurally simple control of the lateral movement and axial rotation of the sliver can is achieved. Then, by controlling the coordinated movement of the two, uniform winding of the fiber sliver is achieved in the sliver can, thereby effectively increasing the capacity of the sliver can, reducing the number of subsequent can changes and splicing, and improving spinning production efficiency.

A screw is screwed into the fifth threaded hole through the sixth fixing hole to achieve a fixed connection between the strip tray 18 and the shim 28.

[0028] In use, the processed fiber strips enter the coiling disc 1 through the connecting port 4, and then exit from the coiling disc 1 through the output port 5. During this process, the coiling motor 3 drives the coiling disc 1 to rotate via the coiling belt 2, which in turn drives the fiber strips in the coiling disc 1 located between the connecting port 4 and the output port 5 to rotate synchronously around the connecting port 4, so that the fiber strips are output in a circular structure. At the same time, the fixed disc 8 is connected to the fiber strips through the lower end of the fiber strip holding cylinder 6. During the connection process, the outer spiral 9 of the fixed disc 8 is aligned with the fiber strip holding cylinder 6. The inner spiral 7 of the lower end of the tube 6 is screwed in until the fixing plate 8 and the strip tube 6 are fixedly connected. After the connection, the first roller 10 and the second roller 11 extend out of the lower end of the strip tube 6. Then, the connected strip tube 6 is placed on the control base plate 17. At this time, the strip tube 6 is placed on the rotating upper plate. During the placement process, the lower end of the strip tube 6 is aligned with the outer circumference of the rotating upper plate. At this time, the first roller 10 and the second roller 11 are suspended in the air with a certain distance between them and the rotating upper plate.

[0029] The strip drum rotation motor drives the upper rotating plate to rotate via a control belt, which in turn drives the strip drum 6 to rotate synchronously along the axial direction. During the rotation of the upper rotating plate, friction causes the support balls of the first, second, and third support ball devices, which are in close contact with it, to rotate, thus supporting the rotating upper rotating plate and achieving stable support for the strip drum 6, which has a certain weight. At the same time, the strip drum transverse motor 19 drives the ball screw to rotate, thereby realizing the vertical movement of the screw during the rotation process. This, in turn, drives the connecting crossbar to move vertically in sync, thereby causing the fixed lower plates of the left and right coiling devices to move horizontally in sync along the vertical direction. This, in turn, causes the sliver canister 6 to move vertically in sync. Furthermore, the direction of the output speed of the sliver canister 19 is changed to allow the sliver canister 6 to move vertically from back to front or from front to back. During the fiber sliver output process, the control base 17 drives the sliver canister 6 to rotate axially and move horizontally in the vertical direction in coordination. This process includes the following steps: Step 1: During the first start-up, the equipment is started at a low speed of less than 50 m / min. The coiling disc 1 and the sliver can 6 rotate simultaneously. During this process, a speed encoder is installed on the front roller of the drafting system of the drawing frame or the large pressure roller of the carding machine. At this time, the speed encoder detects the rotation speed of the front roller or the large pressure roller in real time. And the radius of the front roller or large pressure roller is The radius of the ring is Let's assume that the scaling factor is then input through the touchscreen. Real-time calculation of the rotational speed of the coil disc 1 The holding drum 6 rotates axially according to the coil ratio set at the last stop. The coil ratio refers to the ratio of the rotation speed of the coiling disc 1 to that of the holding drum 6. At the same time, the holding drum 6 moves laterally along the vertical direction to find the origin. During the origin finding process, on the one hand, it is necessary to ensure that the center of the coiling disc 1 is located on the straight line of the lateral movement of the holding drum 6, and on the other hand, it is necessary to ensure that the output port 5 of the coiling disc 1 is vertically aligned with the edge of the holding drum 6.

[0030] Step 2: After the sliver collection drum 6 finds its origin, the control chassis 17 drives the sliver collection drum 6 to rotate axially and move laterally in the vertical direction. During this process, the sliver collection drum 6 first moves laterally in the vertical direction from back to front with varying speed from the origin, and then moves laterally in the vertical direction from front to back with varying speed, until it returns to the origin. At the same time, the sliver collection drum 6 rotates axially with varying speed, and the rotation angle is a circle. This causes the fiber sliver output from the output port 5 of the coiling disc 1 to form the first tangent to the inside of the sliver collection drum 6 with a diameter of [missing information]. The first circular cotton pad.

[0031] Step 3: Stop the horizontal movement of the strip-holding drum 6 along the vertical direction, and set the rotational speed of the strip-holding drum 6 to [unclear]. Duration ,in The number of first circular cotton pieces set along one circumferential direction of the holding tube 6, and then forming a second one tangent to the holding tube 6 with a diameter of [missing information] according to the second step. The first circular cotton pad.

[0032] Step 4: Continue step 3 until the fourth step is formed. A strip tangent to the 6-piece serving tube with a diameter of [missing information]. The first circular cotton pad.
