Drum needling machine

Abstract

A drum acupuncture machine belongs to the field of non -textile machinery.Including a pair of chassis, the needle beam is opened on the wall plate into the sector, and the transmission box is set on the horizontal rack under the chassis; the first and second main axis are supported between a pair of chassis;The first and second spindle connection; the driving mechanism of the roller is connected to the first spindle; the upper roller and the lower roller are matched with the driving mechanism;The middle part of the needle beam is fixed to the lower needle board, and the thorns are arranged on the lower needle plate; a pair of connecting rod swinging the traction mechanism, connecting to the link mechanism, and connecting with the second main axis;The connecting lever traction agency includes active link wheels, first transition sprockets, first, and second piercing rod chain, traction transmission chain, first lead rod, second lead rod, and second transition sprocket.Advantages: high efficiency, short process, saving energy; improving the grade of textile products.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a drum-type needling machine, which is used for needling a multi-layer non-woven fiber cotton web which is successively opened by an opener, carded by a carding machine and laid by a web-laying machine. Stabbed into non-woven products. Background technique [0002] Acupuncture machines are special equipment for processing non-woven products, and are divided into upper needling machines, lower needling machines and upper and lower needling machines according to the form of needling. Among them, the upper needling machine and the lower needling machine are customarily called single needling needling machines, while the upper and lower pair needling machines are customarily called double needling needling machines. [0003] There is no shortage of technical information about acupuncture machines in Chinese patent documents, such as: CN2421299Y (double-punchi...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned needle loom with flat structure is currently the only structure used in the industry (non-woven product manufacturers), but it has been used for a long time Practice has proved that there are two main technical problems in this needle loom: First, because the supporting plate and the stripping plate are in a static state when the needle loom is working, there is no squeezing force or rolling force on the fiber cotton web. Therefore, the acupuncture machine cannot complete the entanglement and puncture of the high-weight (the number of layers of the fiber cotton web and the thickness of the fiber cotton net) at one time. If it is zero, it means step-by-step needle punching. First, it needs to punch a low-weight, that is, a relatively thin pre-needled nonwoven fabric, and then use two or more layers of pre-needled nonwoven fabrics for composite punching ( Also known as final thorns), in order to achieve the required grammage of nonwoven products

The drum needle loom can eliminate the aforementioned technical problems. However, since the needle plate on the needle beam of the drum needle loom is located in the drum chamber of the drum, if the needles arranged on the needle board cannot be guaranteed to move longitudinally in an elliptical trajectory, Then, on the one hand, the non-woven fiber cotton web will be pulled, and on the other hand, there will be a danger of hitting the needle.

Therefore, the applicant has carried out an in-depth and detailed literature search, but there is no technical inspiration that can be used for reference in the published Chinese and foreign patents and non-patent literature so far.
