Problems solved by technology

The unwinding tension of most warp beams is controlled by friction plate damping and weight pressure control. Most of these methods are manually adjusted, which cannot well control the tension at which the sizing machine stops or starts.

Embodiment Construction

[0018] This specific embodiment adopts the following technical scheme: it sets up a mathematical model according to the control theory of unwinding:

[0019] Winding model r=sqrt(ro^2+1 / 100*(R^2-ro^2))

[0020] r = radius l = remaining length

[0021] PID adjustment component

[0022] TS TA --> TEMP1

[0023] Inertia model Inertia J=(J100-Jro)*1 / 100+Jro

[0024] J100=full axis inertia

[0025] Jro = Empty shaft inertia

[0026] Inertia compensation TEMP2

[0027] Tension*coil diameter TEMP3(ts-t0)*r

[0028] PID adjustment component + inertia compensation + tension * winding diameter

[0029] TS TA-->TEMP1 TEMP2 TEMP3

[0030] Through the formula established by the above mathematical model, the on-site unwinding operation only needs to set two parameters: the total length of the unwinding yarn and the unwinding tension required for full winding. When producing different varieties, you only need to set the yarn length and tension, saving time, labor, safety and reliabi...

Description

Technical field: [0001] The invention relates to the technical field of electrical control systems of textile machinery, in particular to an unwinding algorithm of a sizing machine. Background technique: [0002] In the spinning and weaving process, sizing is an important production process. With the wide application of shuttleless looms, people have more and more stringent requirements on the sizing parameters of the weaving beam. influences. To avoid the influence of these factors, the sizing machine is required to strictly control the unwinding tension of the warp beam during the production process. The unwinding tension of most warp beams adopts two methods of friction plate damping and weight pressurization control. These methods are mostly manually adjusted, which cannot well control the tension of the sizing machine to stop or start. Invention content: [0003] The purpose of the present invention is to provide a sizing machine unwinding algorithm, which improves...
