Description

A carding machine for reducing fiber backbending hooks

technical field

The utility model belongs to the field of textile processing, and in particular relates to a carding machine for reducing fiber rear hooks.

Background technique

Fiber straightening parallelism, fiber strength and length are important factors affecting yarn quality. One of the main functions of carding is to increase the straightening parallelism of the fibers in the sliver. The improvement of the straightening parallelism of the fibers is beneficial to the subsequent processes such as the combing process to reduce the nodding, and at the same time effectively reduce the distribution range of the fiber speed change point and improve the cost. Yarn evenness level. On the flat carding machine, when the flat and doffer hold the rear end of the fiber, the cylinder combs the front end of the fiber. Since the linear speed of the cylinder is much higher than the linear speed of the flat and doffer, the front hook of the fiber is straightened and It is greatly reduced. When the cylinder holds the front end of the fiber and the flat and doffer card the rear end of the fiber, due to the low linear speed of the flat and doffer, the effect on the rear hook of the fiber is weak. In the carding action area, the cylinder is the main carding Parts, and mainly comb the front hook of the fiber, so the fiber of the back hook in the cotton net output by the doffer accounts for the largest proportion, accounting for more than 50%, which seriously affects the straightening parallelism of the fiber in the sliver.

Such as Chinese Patent Publication No. CN206887285U (disclosure date: January 16, 2018), the title of the invention is a carding machine for multi-section carding, and the utility model discloses a carding machine for multi-section carding. The carding machine includes The frame and licker-in rollers, cylinder and doffer are arranged on the frame from front to back. The carding surface of the cylinder is provided with front fixed cover, front movable cover, middle fixed cover, The movable cover and the rear fixed cover, the front end of the front movable cover is provided with a front cover cleaner, the front end of the rear movable cover is provided with a rear cover cleaner, and the adjacent front side of the rear cover cleaner is provided with a suction The cotton air duct and the cotton suction air duct are connected to the dust filter system through pipelines. The number of front fixed covers is 2 4, the number of middle fixed covers is 2 4, and the number of rear fixed covers is 1 3 root. The carding machine removes the linters and impurities on the cotton through multiple carding areas and sets up a corresponding cleaning structure, so that the neps/grain g 1 of the sliver is reduced from 25 to 14 15, and the evenness CV/% A drop of about 5% will result in a better product. The front fixed cover plate that this utility model is provided with supplements the carding effect to fiber, but little improvement for the straightening effect of fiber rear crotch.

Such as Chinese Patent Publication No. CN204039573U (disclosure date: December 24, 2014), the title of the invention is a novel carding machine, and the utility model discloses a novel carding machine, which includes a feeding mechanism, a carding mechanism, a stripping Mechanism and strip forming mechanism, the carding mechanism includes a breast cylinder and a main cylinder, and at least three pairs of breast cylinder work and stripping roller groups are arranged above the breast cylinder, and each pair of breast cylinder work and stripping roller groups includes One breast cylinder working roller and one breast cylinder depilling roller, there is a movable flat carding area directly above the main cylinder, a rear fixed flat carding area at the back and upper part of the main cylinder, and a rear fixed flat carding area at the front and upper part of the main cylinder There is a front fixed cover carding area, and a doffer is set immediately in front of the main cylinder; a pre-opening cylinder is set behind the breast cylinder, and a transfer roller is set between the pre-opening cylinder and the breast cylinder. A pair of pre-opening working and dehairing roller groups are arranged above the pre-opening cylinder, and the pair of pre-opening working and dehairing roller groups include a pre-opening working roller and a pre-opening dehairing roller. The carding machine mentioned in this utility model obviously reduces the degree of fiber damage, but this carding machine is still insufficient for the straightening effect of the crotch hook after the fiber.

Utility model content

The technical problem to be solved by the utility model is to provide a carding machine with reduced fiber back hooks to solve the above problems.

In order to achieve the above object, the technical solution adopted by the utility model is: a carding machine with reduced fiber rear hooks, including a cylinder and a straightening device arranged at the front of the cylinder, and the straightening device consists of Composed of a roller and a roller card clothing, the rotation of the roller is opposite to that of the cylinder, and the roller card clothing is arranged parallel to the teeth of the cylinder card clothing.

In the prior art, when the cylinder holds the fiber front end, the cover plate and the doffer card the fiber rear end, because the cover plate and the doffer line speed are small, the effect on the fiber rear hook is relatively weak, so the fiber rear end gets smaller Color straightening effect, there are more hooks. The beneficial effects of the utility model are: a kind of carding machine provided by the utility model with reduced fiber rear hooks is provided with a straightening device at the front of the carding machine cylinder, and the straightening device is composed of a roller and a roller card clothing, so After the fiber enters the straightening action area composed of the cylinder and the straightening device, the cylinder card clothing holds the front end of the fiber, and the roller card clothing combs the rear end of the fiber. The hook has a strengthened straightening effect, and the parallelism of fiber straightening is greatly improved. This setting has a good effect on straightening the hook after the fiber, so that the straightening parallelism of the whole fiber is improved, and the subsequent operation process of combing is further reduced.

On the basis of the above technical solutions, the utility model can also have the following further specific selections or optimization selections.

Specifically, the specification and model of the roller card clothing is the same as that of the cylinder card clothing. In this way, it is ensured that the card clothing of the cylinder and the wire of the cylinder are as consistent as possible in the ability to card and transfer fibers.

Specifically, there are 1-5 straightening devices. A plurality of straightening devices can be installed, which is beneficial to the straightening effect of the rear hook of the fiber after repeated times, and is beneficial to the improvement of the parallelism of the straightening of the fiber.

Specifically, the roller is connected with a variable frequency motor, and the rotation speed of the roller can be adjusted by the variable frequency motor. According to the different conditions of the fibers, when carding the fibers with light back hooks, the roller speed can be appropriately reduced; when carding the fibers with serious back hooks, the roller speed can be increased as much as possible. The straightening effect of the straightening device on the fiber rear hook is adjusted by adjusting the rotating speed of the roller. The device of the utility model has reasonable design, simple structure, very convenient installation and disassembly, and has little influence on the operator's operation.

In addition, the utility model also provides a spinning method using the above-mentioned carding machine that reduces the hook after fiber reduction, which includes the following steps:

1) After the fiber is output from the carding action area between the cylinder and the cover plate, it is brought into the straightening action area between the cylinder and the straightening device by the cylinder card clothing on the cylinder;

2) After the fiber is processed by the straightening action zone, it is brought into the working action area between the cylinder and the doffer by the cylinder card clothing.
