Lapper with air feeding device for cotton passing face

A technology of air supply device and lapping machine, which is applied in the direction of lapping mechanism, textile and paper making, fiber processing, etc. It can solve the problem that the unevenness of cotton laps is difficult to reach the ideal value, destroying the uniform distribution of cotton layers, rolling and crowding of cotton blocks and other problems, to achieve the effect of reducing the transverse unevenness, improving the quality of laps, and ensuring the quality of yarn

Problems solved by technology

If the speed of the fan is too high, the cotton layer will be thicker on both sides and thinner in the middle, which will increase the unevenness and reduce the nodding of beaters; if the speed of the fan is too low, it will easily cause the cotton block to roll and be crowded in front of the dust cage phenomenon, thereby destroying the uniform distribution of the cotton layer
The adjustment of fan speed is restricted by many factors and cannot achieve the ideal state
Even if the ideal fan air volume is achieved, since the tuyere of the dust cage is at both ends of the dust cage and connected to the air duct, the suction at both ends is always greater than that in the middle, and the cotton layer is still thick on both sides and thin in the middle, and the unevenness of the lap is difficult to achieve ideal value

Embodiment Construction

[0010] Such as figure 1 As shown, the lapping machine with the cotton curved surface supplementary air device includes a beater support plate 2, a comprehensive beater 1 is arranged above the front end of the beater support plate 2, a cotton board 3 is arranged at the rear end of the beater support plate 2, and a cotton board 3 is arranged at the rear end of the beater support plate 2. The front end gap is arranged on the rear end below of the beater supporting plate 2, and the front end face of the cotton board 3 is a curved surface. Such as figure 2 shown.

[0011] A pair of dust cages 4 for agglomerating the cotton layer are arranged at the rear end of the cotton passing board 3, and the rear side of the pair of dust cages 4 are three pressing rollers 5, 6, 7. The cotton block output by the comprehensive beater 1 is adjusted by the curved surface air supply plate 3 to form a uniform cotton block adsorbed on the surface of a pair of dust cages 4, and merged into a uniform...

Abstract

The invention provides a lapper with an air feeding device for a cotton passing face, relates to the field of textile machinery and particularly relates to a cotton passing device structure of a lapper. The lapper comprises a beater supporting board; a comprehensive beater is arranged above the front end of the beater supporting board; a cotton passing board is arranged at the back end of the beater supporting board; a pair of dust cages for a cohesion cotton layer are arranged at the front end of the cotton passing board; the back end of the beater supporting board is arranged in a gap at the front end of the cotton passing board; and the front end face of the cotton passing board is a curve. According to the lapper provided by the invention, the cotton passing curve is additionally arranged on the lapper for air feeding, so that a cotton layer is transversely and uniformly distributed, and the transverse unevenness is obviously reduced. The unevenness of a chemical fiber lap can be controlled within 1%, so as to obviously improve the lap quality and lay a good foundation for ensuring the yarn quality.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to the structure of a cotton passing device of a lapping machine. Background technique [0002] Blowing series lap forming machine is used to make a cotton layer by a pair of dust cages and fans before lapping, and then make the cotton layer into a cotton lap of a certain specification. The function of the dust cage is to evenly absorb the cotton blocks output from the beating chamber on the surface of the upper and lower dust cages, and then combine them into a cotton layer with a certain thickness and send it out. To make the condensed cotton layer on the surface of the dust cage uniform, the speed of the fan should match the speed of the beater. If the speed of the fan is too high, the cotton layer will be thicker on both sides and thinner in the middle, which will increase the unevenness and reduce the nodding of beaters; if the speed of the fan is too low, it will easily cause...
