Opening device on opener

Abstract

The invention discloses an opening device on an opener, which comprises an opening roller, wherein a combing piece is arranged on the outer cylindrical surface of the opening piece; the opening device also comprises a separating-combing plate arranged below the opening roller; the upper surface of the separating-combing plate is in the shape of a concave circular arc in the transverse direction; the upper surface of the concave circular arc of the separating-combing plate and the opening roller are arranged to have the same central shaft; another combing piece matched with the combing piece on the opening roller is arranged on the upper surface of the concave circular arc; and the separating-combing plate is arranged on the opener through a separating-combing plate bracket. Fiber is transferred onto the separating-combing plate, and then grabbed by the combing piece on the separating-combing plate, and the combing piece on the opening roller produces scratching force on the fiber through the rotation of the opening roller so as to complete opening. As the separating-combing plate has the upper surface of the concave circular arc bearing the fiber, the effect of the opening is better than that of first opening in the background art. Therefore, the opening effect of the opener having the opening device is better than the secondary opening effect of two sets of openers arranged in series in the prior art, and the opening device has the advantages of simplifying equipment and reducing set occupied area, thereby reducing production cost.

Description

technical field [0001] The invention relates to an opening machine, in particular to an opening device on the opening machine. Background technique [0002] In the opening machine, the fibers are sent in through the conveying curtain, and a pair of rollers are arranged downstream of the conveying curtain, and an opening roller is arranged downstream of the pair of rollers. For card clothing, there is a pressing roller above the conveying curtain. The pressing roller rotates and presses the input fiber to limit the height of the input fiber. The fiber pressed by the pressing roller is then sent between a pair of rollers, and then passed After the roller is conveyed, it is opened by the metal card clothing on the opening roller. The rotation speed of the roller is lower than that of the opening roller, so the fiber can be firmly clamped by the roller, and the fiber can be opened by the scraping force of the metal card clothing on the opening roller. In the prior art, one ope...

AI Technical Summary

Problems solved by technology

In the prior art, one opening by the opening roller usually cannot achieve the required opening effect, and two openings are generally required, that is, two sets of the above-mentioned opening machine need to be connected in series, which leads to an increase in the cost of the production equipment. In addition, the two sets of opener equipment occupy a large area, which further increases the production cost.
