Improved needle machine

Abstract

The invention relates to an improved needle machine, which comprises a frame. A motor is arranged on one side of the upper portion of the frame and connected with a horizontal rotating shaft through abelt. The horizontal rotating shaft is mounted on the frame through a bearing and provided with two connecting rod necks connected with connecting rods, the connecting rods are connected with pistonswhich are connected with push rods, and the push rods are connected with needle plates. Bidirectional guide columns are arranged outside the push rods, oil cylinders are arranged below the bidirectional guide columns and connected with a stripper plate, a pulling mesh plate is arranged below the stripper plate, and the lower portion of the pulling mesh plate is connected with screw rods which areconnected with worm gears. The improved needle machine has advantages that high connectivity is achieved, layering and break stitches are avoided, continuous needling is performed to gradually permeate a plurality of fixed layers, the longitudinal reinforcing fiber content of a prefabricated part is increased, and needling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of textile equipment, and in particular relates to an acupuncture machine. Background technique [0002] Existing mechanical equipment of acupuncture machines needling fiber multi-layer quasi-three-dimensional prefabricated parts, in order to meet the high requirements of needling thickness, density, and fiber content in the vertical direction, each link process is controlled by manual operation. In the process of needling products, Supporting parts such as the support plate and column are fixed parts and cannot be lifted automatically. Every time the needle is lifted, the acupuncture equipment has to stop once in time to manually lift the needle downward. This makes it difficult to lift the needle and causes many broken needles and layers of thickness. Unevenness, bending of non-woven fibers, and connection of upper and lower needles make the product layered, the density is uneven, and the tensile strength ...

In the process of needling products, Supporting parts such as the support plate and column are fixed parts and cannot be lifted automatically. Every time the needle is lifted, the acupuncture equipment has to stop once in time to manually lift the needle downward. This makes it difficult to lift the needle and causes many broken needles and layers of thickness. Unevenness, bending of non-woven fibers, connection of upper and lower needles make the product layered, uneven density, tensile strength can not reach, so that the CVD deposition process of subsequent products will bring negative effects such as unstable quality
