Drum needling machine

Abstract

The invention relates to a drum needling machine, which belongs to the field of nonwoven machinery. The drum needling machine 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, a pair of connecting rod swinging traction mechanisms and a power transmission mechanism, wherein a wallboard is provided with a needle bream abdication cavity, and a lower crossarm of each case is provided with a transmission case; the first main shaft and the second main shaft are supported between the pair of cases; the link mechanisms are connected with the first main shaft and the second main shaft; 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; an upper needle plate is fixed in the middle part of the upper needle beam, an upper needle is arranged on the upper needle plate, a lower needle plate is fixed in the middle part of the lower needle beam, and a lower needle is arranged on the lower needle plate; the connecting rod swinging traction mechanism is connected with the link mechanisms and also connected with the second main shaft; and the power transmission mechanism is connected with the first main shaft, and each connecting rod swinging traction mechanism comprises a driving chain wheel, a first transitional chain wheel, a first traction rod chain wheel, a second traction rod chain wheel, a traction transmission chain, a first traction rod, a second traction rod and a second transitional chain wheel. The drum needling machine has advantages of high efficiency, short flow, energy conservation and capability 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 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.
