Double-drum needling machine

Abstract

The utility model relates to a double-drum type needling machine, which belongs to the 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 on 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, It is connected with the first and second main shafts; the roller driving mechanism is connected with the first main shaft; the upper roller and the lower roller cooperate with the roller driving mechanism; the upper needle beam and the lower needle beam are fixed on 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 also connected with the second main shaft; power transmission The mechanism is connected with the first main shaft, and the pair of link mechanisms each include first and second connecting rods, first and second transition connecting rods, an upper traction plate and a lower traction plate. Advantages: high efficiency, short process, saving energy; improving product quality; ensuring smooth movement of upper and lower needle beams.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and specifically relates to a double-drum needle punching machine, which is used for performing multiple layers of non-woven fiber cotton webs sequentially 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 a flat structure is currently the only structure used in the industry (non-woven product manufacturers), but it has been proved by long-term practice that this kind of needle loom mainly has the following two technical problems : one, because the support board and the stripping board are in a static state when the needle punching machine is working, there is no extrusion force or rolling pressure on the fiber cotton web, so the needle punch cannot complete the high grammage at one time. (The number of fiber cotton net layers is large and the thickness is large) The entanglement and puncture of fiber cotton net layers are usually dealt with by acupuncture. Heavy, that is, relatively thin pre-needled nonwovens, and then two or more layers of pre-needled nonwovens are combined with the main needle punching machine (also called final punching), so as to achieve the required grams of nonwoven products. Heavy

However, in view of the fact that there is no technical information on double-drum needle looms in the published Chinese and foreign patents and non-patent literature, it undoubtedly increases the technical design difficulty of connecting the link mechanism with the upper and lower needle beams
