Knotless needling machine

Abstract

The invention provides a knotless needling machine, and belongs to the technical field of non-woven machinery. The needling machine comprises a rack, a needle beam, a needle beam driving mechanism, a needle hole board, a moving beam, a moving beam opening / closing mechanism and a moving beam lift adjusting mechanism, wherein an upper top plate is fixedly arranged on the top of the rack and a base plate is fixedly arranged at the bottom of the rack; a pair of upper beams are fixedly arranged on the upper top plate; a needle bed is fixed at the bottom of the needle beam; and needles are arrangedon the needle bed. The needling machine is characterized in that the right end of the moving beam is arranged on a vertical shaft; the vertical shaft is fixed between the upper top plate and the baseplate; the left end of the moving beam forms a free end; the moving beam opening / closing mechanism comprises an acting cylinder, a press arm and a press block; a carrier roller is arranged at one side, facing the press block, of the moving beam and a tension roller is arranged at the other side of the moving beam; and a limiting rod is fixedly arranged at the side at the right end of the moving beam. The needling machine has the following advantages: locking and opening of the moving beam can be guaranteed; when the limiting rod arranged on the moving beam is hindered by the vertical shaft, the opening of the moving beam is extremely limited; stable lifting of the moving beam is guaranteed; and the needling machine has a simple integral structure.

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. [...

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.
