A method for preparing belly yarn through an adjustable variable speed rotary head

Abstract

The invention discloses a method for preparing belly yarn through an adjustable and variable-speed rotary head, which includes: setting parameters through an input device, the parameters at least including: a first group of data and a second group of data; the parameters input by a PLC control system Calculate the PID value or duty cycle; the PLC control system transmits the data to the drive system; the drive system drives the motor to run alternately at different speeds at the set speed and time; the motor is connected to the rotary head to drive the rotary head to rotate at different speeds run alternately. The present invention inputs at least two sets of rotational speed and time data through the input device, controls the rotary head to run alternately at different rotational speeds and times through the motor, and the rotational speed of the rotary head determines the grammage or the weight of the feathered yarn to be twisted. According to the amount of wire feeding, the method of preparing belly yarn by adjusting the rotation speed of the rotary head has higher production efficiency and better economic benefits than the traditional preparation method of adjusting the rotation speed of the roller structure.

Description

technical field [0001] The present invention relates to the technical field of preparation method of pot belly yarn, more specifically relates to a method for preparing pot belly yarn through an adjustable variable speed rotary head. Background technique [0002] There is a rotary head part in the yarn machine / chenille yarn machine. The rotary head is driven by a motor to rotate at a high speed. The function of the rotary head is to twist multiple single yarns into feather yarn. [0003] Because the rotary head runs at a constant speed, the weight of the feather yarns formed by twisting and locking of the rotary head is generally the same, so that the thickness of the final yarn is uniform. [0004] Tubly yarn refers to a section of thick and thin yarn on a yarn in the finished woolen yarn, which is one of the appearance defects of the finished woolen yarn. [0005] But the belly yarn is suitable for making sweaters in winter, and the personalized style is very fashionable,...

Problems solved by technology

[0009] In this way, it can be concluded that in the prior art, the mode of generating the belly yarn by adjusting the rotating speed of the roller structure, stopping the front roller gap or overfeeding the roving through the middle and rear roller gap is all by adjusting the motion state of the roller. Adjustable, but the roller structure of the production equipment in the prior art is relatively complicated, and it is relatively difficult to adjust its operating state, especially repeated adjustments, and it is not easy to adjust, and the roller structure speed is changed through the electric gearbox Changes will lead to lower yields, thereby reducing economic benefits
