Opener

Abstract

The invention provides an opener which comprises a preliminary opening assembly, an opening cylinder and a stripping roll set. The preliminary opening assembly comprises a support frame, preliminary opening roll sets, transfer rolls, automatic tensioning machines and a roll set transmission mechanism, the opening cylinder comprises a rough opening cylinder and a fine opening cylinder, the rough opening cylinder comprises a cylinder mounting ring and a rough opening needle bed, and the fine opening cylinder comprises a cylinder mounting ring and a fine opening needle bed. The opener has the advantages that the cylinder mounting rings comprise inner mounting rings and outer mounting rings, the outer mounting rings are slidably mounted on the inner mounting rings, the rough opening needle bedand the fine opening needle bed are mounted in needle loop mounting grooves, and accordingly the opener is convenient to disassemble; only the needle beds with different specifications need to be changed when different materials are about to be opened, accordingly, the different materials can be opened by the opener, and the integral cylinders do not need to be changed; the preliminary opening assembly is additionally arranged at the fronts of feeding rollers, the materials are preliminarily opened before being fed into the rough opening cylinder, and accordingly opening effects and the workefficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to an opener. Background technique [0002] Opening machine, the process of loosening the compacted and entangled fiber raw materials and removing impurities. Various fiber raw materials for spinning, such as raw cotton, wool, chemical staple fiber, cotton, hemp, polyester, rags, etc., are mostly transported into the textile mill in the form of bales. In order to spin high-quality spun yarn, first It is necessary to loosen the raw materials, remove various impurities, and mix them uniformly. It mainly loosens fibers, cotton, textiles and other materials, and loosens large entangled fibers into small pieces or bundles by tearing, and at the same time, it is accompanied by mixing and impurity removal during the loosening process. [0003] Such as the Chinese patent publication number is a kind of opener provided by "CN106987929A", comprising a frame, a pair of feeding roll...

AI Technical Summary

Problems solved by technology

[0004] The opener provided by the above application can achieve accurate positioning by inserting the needle plate and the roller body, but when a certain part of the cylinder is damaged, especially the needles on the cylinder are easily damaged. During the disassembly and installation process of replacement parts, it is easy to wear and tear the material. Another example is the opening mechanism provided by the Chinese Patent Publication No. "CN102747458A". The finished installation layer, in which the plates are connected by mortise and tenon, and the mortise and tenon connection is more likely to be damaged during disassembly and assembly, which will affect the assembly effect

At the same time, during the working process of the cylinder, since the needle plate is plugged in, misalignment easily occurs if the positioning element is not installed, which affects the opening effect and has certain safety hazards

In addition, most openers only enter the cylinder directly after passing through the feeding rollers, lack of pre-opening components, and easily damage the cylinder
