An adjustable fan energy-saving device for a roving frame

Abstract

The invention discloses a fan-adjustable energy saving device of a roving machine. The fan-adjustable energy saving device comprises a sensor, an intermediate relay, a dual-delay relay and a PLC (programmable logic controller) which are sequentially connected, the sensor is mounted below an air blowing and sucking guide rail on the roving machine, and the PLC is connected with an upper air blowing and sucking motor controller and a lower air blowing and sucking motor controller. The fan-adjustable energy saving device is small in input cost, convenient to mount, wide in application range, capable of being matched with various roving machine equipment and capable of correspondingly and separately adjusting running time and intermittent time of an air sucking motor according to different varieties produced by the roving machine, and requirements on both quality and energy saving are met, so that the problem that the roving machine is high in energy consumption is solved.

Description

technical field [0001] The invention relates to a component of a textile machine, in particular to an adjustable energy-saving device for controlling the on-off time of a fan of a cotton spinning roving frame. Background technique [0002] In the production process of cotton spinning, from drawing frame to spun yarn, before using the ultra-large draft spinning frame, it is necessary to elongate the sliver through the roving frame, spin it into roving, and then pass the roving through the drafting and twisting of the spinning frame. into a yarn that meets the requirements. In order to ensure the cleanliness of the drafting rollers and the table top of the roving frame, the roving frame has two cleaning devices, the upper blowing and suction fan and the lower suction motor. The upper blowing and suction fan is mainly used to clean the upper pile and the body of the roving frame, and the power consumption is 1.5kW; currently The down-sleeve rotary cleaning device used at home ...

AI Technical Summary

Problems solved by technology

[0003] But there are two disadvantages: 1. The down suction motor is turned on continuously, which consumes a lot of energy and has high production costs.

2. The down suction motor cannot be adjusted and cannot meet the production demand, which affects the production efficiency

When producing polyester and other chemical fibers with a length of about 38mm, or producing combed high-count yarns of more than 80 counts, since the roving frame uses fiber strips with long fiber length and less short pile, the pile pile and the table top of the roving frame There are very few flying flowers, so the uninterrupted work of the roving frame using the suction fan is a waste of energy

In addition, the varieties produced by cotton spinning mills are constantly adjusted according to the market. The changes in the length of the raw material fibers and the content of short fibers brought about by the changes in varieties will cause large changes in the pile accumulation under the roving frame and the fly on the table of the roving frame at any time. , the downdraft fan cannot be cancelled.
