Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, and particularly relates to an annular felt blanket needling machine. Background Art

[0002] When the annular felt blanket needling machine is operating, under the drive of power, the needling drive mechanism drives the push rod to move up and down, and then drives thousands of grooved needles on the needle plate to move up and down; at the same time, the power output shaft of the needling drive mechanism drives the cloth feeding roller to rotate through chain transmission, and then drives the blanket to be needled to move forward. Since there are thousands of needles on the needle plate, when the needles pierce down, the blanket is restricted by the needles and stops moving; when the needles are lifted upwards, the elastic blanket moves forward under the action of the cloth feeding roller, causing the blanket to move forward by a certain distance, and this process is repeated.

[0003] Due to the large number of needles on the needle plate, some needles are slightly inclined or slightly bent, resulting in unsatisfactory neatness of the needles; since the existing cloth feeding step distance is fixed, obvious strip traces extending along the blanket will be left on the blanket corresponding to the irregular parts of the needles, thus causing an uneven needling visual effect and affecting the quality of the blanket.
