Background

The control system of the traditional coiling process is characterized in that a cotton layer is formed by cotton storage, pre-opening cotton, a flat cotton, a needle cotton and a vibration cotton box before the formation of the cotton layer, then the cotton layer is conveyed into a balance crank (harp), the thickness of the cotton layer is sensed by the balance crank (harp) device to adjust the speed change of a cotton feeding roller, the consistency of the cotton quantity is adjusted, but the cotton quantity is difficult to be ideal due to the low precision and limited sensing accuracy of the balance crank (harp) structure.

The cotton layer adjusted by sensing is attached to the dust cage after being loosened by a beater, and the cotton layer is formed by rotating one surface of the dust cage and adsorbing cotton on the other surface of the dust cage, so that the cotton layer is not uniformly distributed due to unstable wind power and structural reasons, and the quality requirement is more difficult to achieve.

The invention has two core technologies: firstly, a cotton supply machine with a double-layer double-pressure structure is adopted; and the other is that five pressure detection sensors are adopted.

The working principle of the cotton feeder with the double-layer double-pressure structure is as follows:

the wind direction in the technical scheme of the invention is used for detailed description, so that the technical scheme of the invention can be further known by the technical personnel in the field. In the known invention, the two dust boxes are communicated with the cotton supply pipe 12, the two dust boxes are communicated with each other, the first dust box is communicated with the upper cotton box, and the purpose of the arrangement is to form an internal air circulation. The pressurizing fan pressurizes and blows the air from the cotton supply pipeline 12 and the two dust collecting boxes upwards, the air pressure buffering boxes buffer the air and enter the cotton supply pipeline 12, and at the moment, the air flow can not only go downwards, but also has upward air flow.

The wind pressure regulating plate can be opened by the upward wind flow, and the specific description shows that the wind pressure regulating plate is hinged below the exhaust net, so according to the gravity principle, the wind pressure regulating plate can be in a closed state, when the upward wind flow opens the wind pressure regulating plate, cotton enters a cotton supply channel, and the wind pressure regulating plate is of great importance. When the upward wind flow blows the wind pressure adjusting plate and then enters the upper cotton box, the wind flow can be discharged from the convection port and the dust collection outlet, and meanwhile, the wind flow can enter the first dust collection box and then enter the internal circulation.

The downward wind flow enters the cotton supply pipeline 12 to bring the cotton layer entering the cotton supply pipeline into the cotton feeding roller, the beater and the lower cotton supply roller, and then the cotton layer is discharged from the cotton guide plate to enter the next procedure, and the wind at the moment also enters the two dust boxes to enter circulation.

The working principle of the five pressure detection sensors is as follows: the first pressure detection sensor 101 is arranged on the cotton inlet pipeline 11, the first pressure detection sensor 101 can react and adjust the cotton inlet amount at any time, and if the rear cotton layer is thick, the cotton inlet amount is adjusted by arranging and adjusting data collected by the control center;

the second pressure detecting sensor 102 is disposed on the cotton supplying pipe 12, and is mainly used for detecting the wind pressure and wind speed in the cotton supplying pipe 12, and the wind pressure and wind speed can affect the speed of cotton supplying, and further affect the thickness and uniformity of a cotton layer;

the third thickness detection sensor 103 is arranged on the auxiliary cotton clamping roller 2, mainly detects the thickness of the cotton layer coming out of the first cotton guide plate 7, and further adjusts the thickness of the cotton layer by adjusting the distance between the rollers;

the fourth thickness detection sensor 104 is arranged on the drafting roller, the drafting roller 3 is positioned behind the auxiliary cotton clamping roller 2, whether the thickness of the cotton layer adjusted by the front auxiliary cotton clamping roller 2 is uniform or not meets the requirement or not needs to be further detected by the fourth thickness detection sensor 104, and the uniformity and the standard of the cotton layer are further guaranteed;

the fifth rotation speed detecting sensor 105 is installed in the pressing device 5, where the thickness of the cotton layer and the rotation speed of the roller in the pressing device are detected, if the cotton layer is thick, the roller in the device needs to be accelerated, and then the cotton layer is dragged, and the thickness becomes thin. The five pressure detection sensors are different in labor division, data are accurately controlled through the mobile phone and the arrangement of the control center, the thickness of the cotton layer is accurately controlled, and the quality of the cotton layer is greatly improved.
