What is the mechanism of the opener?

The raw cotton has been opened and mixed to a certain degree after being processed by the automatic grabbing machine, automatic mixing machine, six-stop simple opener and porcupine opener. Some large impurities and part of leaf debris have been removed, but the raw cotton There are also a considerable number of broken seeds, sterile seeds, seed crumbs and so on. In addition, from the perspective of the entire opening and cleaning process, it is close to making cotton rolls. Therefore, the tasks of the opener are:

1. Continue to open, remove impurities, and mix evenly z

2. Control and improve the longitudinal and transverse uniformity of the cotton layer, and make a certain specification of cotton roll.

In the LA004 type opening and cleaning combined machine. The opening machine is composed of the A092A double box feeder and the A076A single beater coiling machine.

The A092A double cotton box cotton feeder is mainly composed of a rear cotton storage box, a middle cotton storage box and a UV" curtain cotton box. The rear cotton storage box includes an adjustment plate 1, a rocker 2 and a corner nail cotton guide roller 3. The middle storage The cotton box includes cotton feeder 4, shaker 5, corner nail curtain 6, cotton uniform roller 7 and cleaning roller 8. "V" curtain cotton box includes cotton stripper 9, Uv" curtain 10 and return roller 11. After the raw cotton enters the cotton storage box on the 12th through the condenser, the adjustment board in the box is used to adjust the thickness of the cotton box and control the capacity of the cotton box. According to the change of the cotton storage height in the cotton box, the rejection grid controls the opening and closing of the electric cotton feed into the cotton hopper valve through a mercury switch to keep the cotton storage height constant. The lower pair of corner nail cotton guide rollers rotate according to the needs of the middle cotton storage box. The raw cotton is fed into the middle storage box by the cotton conveying curtain. When the amount of cotton in the box is too much or too little, a set of technical and ritual mechanism linked with the ring plate controls the angle nailing cotton guide roller to feed or stop the cotton. The raw cotton quilt fed by the feeding curtain is picked up by the corner nail curtain and transported upwards. When encountering the equalizing roller, part of the larger cotton lump is shot down and returned to the cotton box to remix with the raw cotton fed by the feeding curtain. There is a certain distance between the corner pin and the cotton uniform roller, which can be adjusted by hand wheel according to the production needs. The cotton lump left on the cotton roller is removed by the cotton roller. The cotton lump brought out by the corner nail curtain is thickly stripped by the cotton stripper and falls into the "V"-shaped curtain cotton register. The return roller located above the back "V" shape returns the excess raw cotton in the box to the middle box to control the box capacity to maintain a certain height. The central cotton layer of the "V" curtain is evenly spread on and on the cotton conveyor curtain of the beater lap machine. The "V"-shaped curtain inlet distance can be adjusted according to the tank capacity.
