Double-drum rotary-type needling machine

Abstract

A double-drum rotary needling machine belongs to the technical field of non-woven machinery. It includes a pair of chassis, a needle beam is set on the wallboard to penetrate into the relief cavity, and a transmission box is set in the middle of the lower cross frame of the chassis; the first main shaft and the second main shaft are supported between the pair of chassis; a pair of connecting rod mechanisms , located in the cavity of a pair of chassis, connected with the first and second spindles; the roller driving mechanism, connected with the first spindle; the upper roller and the lower roller, cooperating with the roller driving mechanism; the upper needle beam and the lower needle beam, in The upper needle plate is fixed in the middle of the upper needle beam, the upper needles are arranged on the upper needle plate, the lower needle plate is fixed in the middle of the lower needle beam, and the lower needles are arranged on the lower needle plate; a pair of connecting rod swing traction mechanism is connected with the connecting rod mechanism And it is also connected with the second main shaft; a power transmission mechanism, the power transmission mechanism includes a frequency conversion speed regulating motor, a first transmission wheel, a transmission belt and a second transmission wheel. Advantages: high efficiency, short process, energy saving; beneficial to improve the grade of non-woven products.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a double-drum rotary needling machine, which is used for multiple layers of non-woven fiber cotton webs which are successively opened by an opener, carded by a carding machine, and laid by a web-laying machine. Needle punching 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: CN2421299...

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

For this reason, 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 Chinese and foreign patents and non-patent literature that have been disclosed so far.
