Anti-blocking needling machine capable of avoiding influence of fiber flock

Abstract

The invention discloses an anti-blocking needling machine capable of avoiding influence of fiber flock, and belongs to the field of needling machines. The anti-blocking needling machine comprises a support; a bottom plate is fixedly mounted in the middle of the top end of the support; guide vertical rods are fixedly mounted at four corners of the top end of the bottom plate; a top plate is fixedly mounted at the top ends of the guide vertical rods; the guide vertical rods are provided with anti-blocking mechanisms which are symmetrically distributed up and down; the anti-blocking mechanisms are provided with needling mechanisms; the two sets of needling mechanisms are of a symmetrical distribution structure; and the two sides of the bottom plate and the two sides of the top plate are fixedly provided with U-shaped protection frames. According to the invention, the two sets of needling mechanisms which are symmetrically distributed up and down are arranged, and a driving assembly is used in cooperation; multiple sets of needling needles in two sets of needling assemblies distributed up and down are distributed in a staggered mode; materials are needled at the same time through the two sets of needling assemblies, so that the needling time of the materials is shortened; and the materials can be needled up and down in a staggered mode, so that the needling effect of the needling machine on the materials is effectively improved.

Description

technical field [0001] The invention relates to the technical field of acupuncture machines, in particular to an anti-clogging acupuncture machine which avoids the influence of lint. Background technique [0002] Acupuncture machine is a kind of blanket-forming equipment that weaves a refractory fiber blanket blank of a certain thickness into a refractory fiber blanket after compaction and needle punching; it uses a triangular or other shaped cross-section, and has barbed hooks on the edges. The needles repeatedly puncture the fiber web. The fiber web unloaded from the cross-forming or air-forming machine is very fluffy when it is fed into the needle loom. It only has a certain strength due to the cohesion between fibers, but the strength is very poor. When the needle penetrates into the fiber net, the barbed hook on the needle will drive the fibers on the surface and sub-surface of the fiber net, and move from the plane direction of the fiber net to the vertical direction ...

Problems solved by technology

[0003] However, most of the existing acupuncture machines use an up and down swing mechanism to drive a single group of acupuncture components to perform periodic lifting, so as to perform one-sided acupuncture on the material. This acupuncture operation can only unilaterally shift the fibers up and down. , resulting in a longer needling time. Secondly, when the needling component is separated from the material, it is easy to stick to auxiliary lint. If it is not cleaned in time, the lint will accumulate too much, which will easily cause the blockage of the needling machine, which will affect the follow-up of the needling machine. For this purpose, we propose an anti-clogging needle loom that avoids the influence of lint to solve the above problems
