Double-drum rotary-type needling machine

Abstract

A double-drum rotary-type needling machine belongs to the technical field of nonwoven machinery and comprises a pair of cases, a first main shaft, a second main shaft, a pair of link mechanisms, a drum driving mechanism, an upper drum, a lower drum, an upper needle beam, a lower needle beam, a pair of connecting rod swinging traction mechanisms and a power transmission mechanism, wherein a wallboard is provided with a needle beam probing abdication cavity, and the middle part of a lower crossarm of each case is provided with a transmission case; the first main shaft and the second main shaft are arranged between the pair of cases; the link mechanisms are arranged inside cavities of the pair of cases and connected with the first and the second main shafts; the drum driving mechanism is connected with the first main shaft; the upper drum and the lower drum are matched with the drum driving mechanism; the middle part of the upper needle beam is fixedly provided with an upper needle plate, an upper needle is arranged on the upper needle plate, the middle part of the lower needle beam is fixedly provided with a lower needle plate, and the lower needle plate is provided with a lower needle; the connecting rod swinging traction mechanisms are connected with the link mechanisms and also connected with the second main shaft; and the power transmission mechanism comprises a variable-frequency speed regulation motor, a first driving wheel, a driving belt and a second driving wheel. The double-drum rotary-type needling machine has advantages of high efficiency, short flow, energy conservation and favorability of improving the grade of a nonwoven product.

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. Perform 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: C...

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.
