Rotary cotton fiber combing machine

Abstract

The invention provides a rotary cotton fiber combing machine which comprises a cotton feeding device, a cylinder device, a top combing device and an outputting device, and is characterized in that: the cotton feeding device is located on the upstream of the cylinder device; the top combing device is located above the cylinder device; the outputting device is located on the downstream of the cylinder device, wherein the cylinder device comprises a cylinder roller; cylinder combing needle plates and nipper devices are uniformly distributed on the cylinder roller at intervals; the number of the cylinder combing needle plates and nipper devices is 1-4; the cylinder roller is driven to do intermittent rotary motion by an intermittent driving mechanism; and during the process of the intermittent rotary motion, when the nipper devices move to the position of the cotton feeding device, the cylinder roller pauses or runs at low speed. The invention provides a fiber-combing and transferring mechanism which is totally different from the present technical principal of the traditional combing machine as well as foreign patent technology. According to the rotary cotton fiber combing machine, a clamping mechanical device is mounted on a single roller doing the rotary motion and the high-clamping times combing speed of the cylinder device under low-speed state is realized.

Description

technical field [0001] The invention relates to a device for classifying or selecting fibers, which is especially suitable for the combing process of cotton fibers and belongs to the technical field of spinning machinery. Background technique [0002] Existing cotton combing machines rely on the reciprocating motion of mechanisms such as complex ratchets, connecting rods and gears to realize the carding process action. The intermittent feeding of the cotton roller, the reciprocating swing of the combing nipper and the top comb, and the reverse, smooth, and stop cycles of the separation roller will directly cause vibration and noise of the equipment. It is difficult for the comber in this working mode to improve the quality of the cotton. The nipper of the combing machine.

[0003] German Trützschler company discloses a kind of drum type combing machine in the patent that publication number is CN101333701A, and this device has following shortcoming: (1) the combing machine of this patent adopts the mode of clustering and clamping fiber, Dozens of nippers are arranged on the drum, and the opening and closing time and position of the nippers are very strict during the rotary motion, too short opening and closing time is difficult to ensure the reliability of the nippers clamping the fiber and the consistency of the fiber length sex

This requires that the corresponding positions and opening and closing times of the nippers on the two drums at the distance point must be strictly consistent, and a slight difference will cause a fiber transfer error

(3) Although this patent also proposes a single-drum combing machine, there are seven nippers evenly distributed on the cylinder drum, there are many clamping devices, and the opening and closing time of the nippers is too short, so it is difficult to ensure the smoothness of the fiber whiskers. Reliable clamping
