Spinning cotton tension test is mainly to measure the spinning tension of large, medium and small yarns and different winding diameters, accounting, uniform tension, peak tension and uneven tension. With a digital bright light velocimeter to observe the shape of the air circle and the inclination of the traveler . Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine.
Tension test principle of carding machine: The spinning tension of the carding machine is tested. The management system places the strain sensor at the sliver channel between the front roller and the yarn guide hook. When the yarn winding force acts on the south sensor, the color changes , it also changes the resistance value and loses the balance of the product. The output signal of the electric cabinet is proportional to the applied tension. After being expanded by the dynamic strain gauge, it is sent to the X-y function recorder together with the signal of the displacement sensor reflecting the movement of the ring pole. , draw the dark line that the tension changes with the rise and fall of the ring plate. At the same time, a microcomputer multi-number analyzer can also be used to collect and process these signals. Finally, the instrument prints out the most east value, the most d fly value, Uniform and very poor pumps. The operation of the active cotton picker is controlled by the computer with the cotton essence BC. According to the set enterprise output value, it is determined that the interval (ie the depth of cotton manipulation) of the students' ability to organize through the capture work in each work cycle is determined, and then the cotton bales are collected from the cotton bales. The height and descent time interval can be used to obtain the number of times that the personnel have completely grasped the cotton bale curtain, and all the pieces are stored in the memory of the BC cotton grasping machine, so that the entire cotton grasping process can be captured by the memory. The tension pressure of the roller press quilt production line is mainly determined by the drafting type, drafting speed, sliver quantity, drafting multiple and drafting distance. The size of the pressure should ensure that the holding force of the roller tongs can be adapted to the drafting force, so that the sliver does not slip under the roller tongs, and regular strip drying is avoided.
