Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0018] combine figure 1 with figure 2 Shown, be used for the weeding device of woolen carding machine, comprise frame 101, be provided with upper grass roller 102, lower grass roller 103 and stripping roller 104 on frame 101, upper grass roller 102 is positioned at the lower grass roller. Above the roller 103, the stripping roller 104 is positioned immediately behind the upper grass roller 102, and is used for stripping the fleece on the upper grass roller 102 surface. In addition, a transmission component 109 and idler rollers 112 are also provided on the frame 101 .

[0019] The frame 101 is provided with a vertical slide block 105 and a horizontal slide block 106 . There are two longitudinal sliders 105, symmetrically arranged on the left and right side wallboards 107, 108 of the frame, and the two longitudinal sliders 105 move up and dow...

Abstract

The invention discloses a weeding device of a woolen combing machine. The weeding device comprises an upper weed pressing roller and a lower weed pressing roller, the upper weed pressing roller is arranged on a longitudinal sliding block which moves in the vertical direction of a machine frame, the lower weed pressing roller is arranged on a transverse sliding block which moves in the front-and-back direction of the machine frame, a first adjusting component is arranged below the longitudinal sliding block, a second adjusting component is arranged in front of or behind a horizontal sliding block, the first adjusting component adjusts the vertical spaced distance between the upper weed pressing roller and the lower weed pressing roller, and the second adjusting component adjusts the horizontal deviation distance between the vertical axial through face of the upper weed pressing roller and the vertical axial through face of the lower weed pressing roller. The horizontal deviation distance between the vertical axial through face of the upper weed pressing roller and the vertical axial through face of the lower weed pressing roller is adjusted, therefore, the contact area of wool is increased when the wool passes through the upper weed pressing roller and the lower weed pressing roller, the upper weed pressing roller and a lower weed pressing roller are pressed in a rubbing mode to enable weeds mixed in the wool to easily fall off, and in addition, due to the fact that the rotating speed of the upper weed pressing roller is smaller than that of the lower weed pressing roller, the twisting effect of the upper weed pressing roller and the lower weed pressing roller on the weed impurities is enhanced.

Description

technical field [0001] The invention relates to a weeding device for woolen carding machines. Background technique [0002] The woolen carding process is very important in the carded wool spinning processing system. Its quality of blending and quality will directly affect the quality, output and production rate of carded wool yarn. The tasks of the woolen carding process are as follows: 1) Thoroughly loosen the mixed material, and comb the block fiber or bundled fiber into a single fiber; 2) Fully mix the various fibers in the mixed material; 3) Straighten the fiber 4) Remove the weeds, coarse dead hair and coarse fibers mixed in the mixture; 5) Make the carded wool net into roving for the spinning machine. Woolen carding machines, including automatic wool feeders, precards, grass presses, cards, bridge machines and sliver machines. The wool is carbonized before entering the grass pressing device. The grass pressing device includes an upper grass pressing roller and a lowe...
