Problems solved by technology

However, this method is a process of experimentation and exploration, without an accurate mathematical model as a guide, and it is not easy to determine the parameters in actual operation. The most critical thing is that it is impossible to obtain the best combination point of "explosive roving" and "spinning efficiency".

Embodiment

[0085] In this embodiment, the production of 556Tex pure cotton carded roving by applying the roving frame equipment of the present invention is taken as an example. The following mechanical parameters and process parameters are obtained by inputting unit 1 and converted to the international system of units:

[0086] Empty bobbin radius R b =0.0225m

[0087] Maximum spindle radius: R e =0.075m

[0088] Roving twist T w =51T / m

[0089] Final spinning speed ω fe =800RPM

[0090] Spinning speed ω fs =1500RPM

[0091] Roving radial thickness d=0.00043m

[0092] Using the mechanical parameters and process parameters obtained by the input unit 1, based on the model in the model unit 2, according to the specific steps for realizing the technical solution according to the present invention, the calculation unit 3 finally obtains the roving frame equipment of this type, and the roving of this type is obtained in the process. Spinning speed curve under parameters, such as Fi...

Abstract

The invention discloses a spinning speed regulating device of a roving machine and a regulating method. The spinning speed regulating device comprises an input unit, a model unit, a computing unit and an output unit, wherein the computing unit is used for computing the angular speed of a bobbin of the roving machine, the angular speed of a flyer of the roving machine and the spinning speed of the roving machine according to the model unit, so as to regulate the spinning speed of the roving machine. According to the spinning speed regulating method of the roving machine, which is disclosed by the invention, accurate mathematical models are taken as bases, and the best combination point of less roving bursting and the highest efficiency can be obtained under a given safety threshold value of roving bursting, so that the highest production efficiency of the machine can be obtained.

Description

technical field [0001] The invention relates to a method in the field of computer application process optimization, in particular to a method for adjusting a spinning speed adjusting device of a roving frame. Background technique [0002] During the spinning process of the roving frame, the spinning speed (characterized by the flyer angular velocity in the industry) is too high or as the diameter of the bobbin continues to increase, the internal tension of the wound bobbin will become larger and larger. When the internal tension of the roving exceeds When the roving is strong, the so-called "burst roving" phenomenon will occur, which will cause the machine to stop, increase the workload of the operator for jointing, and seriously reduce the production efficiency of the roving frame. [0003] After searching the existing technical documents, it is found that under the condition of the spinning type and the process are determined, the current domestic and foreign roving frames...
