Dual-roller needling machine

Abstract

A double-drum needle loom belongs to the field of non-woven machinery. It includes a pair of chassis, a needle beam is set on the wall plate of the chassis to penetrate into the relief cavity, and a transmission box is set in the middle of the lower horizontal frame of the chassis; the first and second main shafts are supported between the pair of chassis; a pair of connecting rod mechanisms , connected with the first and second main shafts; the roller driving mechanism, connected with the first main shaft; the upper roller and the lower roller, cooperating with the roller driving mechanism; the upper needle beam and the lower needle beam, fixing the upper needle plate in the middle of the upper needle beam , arrange the upper needles on the upper needle plate, fix the lower needle plate in the middle of the lower needle beam, and arrange the lower needles on the lower needle plate; a pair of connecting rod swing traction mechanism, connected with the connecting rod mechanism and connected with the second main shaft; power transmission The mechanism is connected with the first main shaft, and the drum driving mechanism includes a first sprocket, a first transmission chain, a bevel gear box, an upper and a lower worm gear box, and a transition sleeve for the worm gear box. Advantages: high efficiency, short process, saving energy; improving product quality; making acupuncture work go smoothly.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a double-drum needling machine, which is used for needling a multi-layer non-woven fiber cotton web which is sequentially 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-punc...

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 applicant's research shows that the double-drum acupuncture machine can eliminate the above-mentioned technical problems. However, if the pair of drums cannot be effectively guaranteed to rotate at the same speed and synchronously, the acupuncture action cannot be realized.

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.
