Knotless needling machine

Abstract

The utility model relates to an endless needle punching machine, which belongs to the technical field of non-woven machinery. It includes the frame, the upper part of which is fixed with an upper top plate, the bottom is fixed with a base plate, and a pair of upper beams are fixed on the upper top plate; the needle beam and the needle beam driving mechanism are fixed on the bottom of the needle beam and the needle bed is arranged with needles; Pinhole plate; movable beam; movable beam opening and closing mechanism; movable beam lifting adjustment mechanism; features: the right end of the movable beam is set on the vertical shaft, and the vertical shaft is fixed between the upper top plate and the base, and the left end of the movable beam is formed as a free end. The opening and closing mechanism of the crossbeam includes a working cylinder, a pressing arm and a pressing block; an idler roller is arranged on the side of the movable crossbeam facing the pressing block, a tension roller is arranged on the other side, and a limit rod is fixed on the side of the right end of the movable crossbeam. Advantages: it can ensure the locking and opening of the movable beam; when the limit rod set on the movable beam is obstructed by the vertical shaft, the limit opening degree of the movable beam is limited; the movable beam can be lifted and lowered smoothly; the overall structure is simple.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to a non-end point needle punching machine. Background technique [0002] The non-end point needle loom mentioned above is also called jointless needle loom, and the concept of no end point means that the needled nonwoven fabric has no joints and forms a ring as a whole. Endless non-woven products are typically paper-making felts and various conveyor belts. Paper-making felts are also called industrial fabrics. If the paper-making felt has joints, on the one hand, it will affect the service life, and it will break during use due to the weak strength of the joints. On the other hand, it will affect the quality of the paper, making the thickness of the paper different. Similarly, if there is a joint in the conveyor belt, it is very easy to crack or even break at the joint during the transmission process, and it will affect the balance of the transmission. [...

AI Technical Summary

Problems solved by technology

However, the structure of the opening and closing mechanism introduced by both CN201122067A and CN102031645A is relatively complicated, and it is difficult to be used for reference by the small endless needling machine for single-side needling.
