Acupuncture machine frame with the function of guiding and supporting the needle board

Abstract

A needling machine frame with the function of guiding and supporting needle plates belongs to the technical field of non-woven machinery. Including the bottom box body, the middle column box body and the bottom box beam, a pair of middle column box bodies are arranged on the top of a pair of bottom box bodies, and needle plate relief chambers are respectively set on the pair of middle column box bodies , the bottom box beam is fixed between a pair of bottom box bodies, a crankcase body is arranged above the pair of middle column box bodies, and a needle beam is arranged below the crankcase body, and the needle beam and Connected by the crankshaft link mechanism, a needle plate is set under the needle beam, the two sides of the needle plate in the length direction are fixed to the needle beam, and the end of the needle plate corresponds to the relief cavity of the needle plate. Needle plate guiding and supporting mechanisms are respectively arranged on the box body and corresponding to the positions of the needle plate abdication cavity. Reduce manpower input, lighten operation intensity, improve efficiency; prevent accidental breakage of needle plate, avoid economic loss and avoid injury to operators; ensure operation safety.

Description

technical field [0001] The invention belongs to the technical field of non-woven machinery, and in particular relates to an acupuncture machine frame with the function of guiding and supporting a needle plate. Background technique [0002] The function of the needle punching machine is to entangle and stab the non-woven fibers to form the required non-woven products, such as non-woven fabrics, non-woven felts, non-joint industrial wool (no joints, that is, non-end industrial wool, such as papermaking felt, various conveyor belts, etc.). There are three main structural forms of the acupuncture machine frame: one is composed of a pair of wall panels facing each other and a wall panel connecting beam connected between the pair of wall panels to make the pair of wall panels form a whole. Such as the "dislocation puncture needle machine" recommended by the Chinese Patent Authorization Announcement No. CN2421298Y; the second is set up facing each other and each consists of a bott...

Problems solved by technology

[0004] Furthermore, as known in the industry, the length of the effective needling area of ​​the needle board needs to be compatible with the width (width) of the non-woven product, that is to say, the larger the width of the non-woven product, the longer the length of the needle board (including the needle beam). It is also correspondingly longer, so there are the following unavoidable technical problems in the following three aspects in the process of pulling the needle plate outwards or pushing it inward through the aforementioned needle plate relief hole: one, because in order to avoid damaging the needle The needles on the board need to be carried by multiple people to work together to keep the needle board suspended from the bottom edge of the needle board chamber, which not only increases the operating strength of the equipment maintenance personnel, but also requires a lot of manpower and The movement is slow; secondly, taking the needle plate pulled out as an example, as the length of the needle plate drawn out increases, the cantilever end of the needle plate will drop. If the support is neglected at this time, the needle plate may break , causing economic losses at the slightest, and at the worst, it will have a safety impact on the equipment maintenance personnel. The same example is inserted into the needle plate when it is loaded. In view of this, the industry says that replacing the needle plate or rearranging the needles on the needle plate is an extremely high-risk operation; the third In the process of pulling out the needle plate and at the moment when the end of the needle plate is completely separated from the needle plate fixing frame, if the protection is neglected, it will suddenly collide with the bottom edge of the needle plate relief cavity, so there is also damage and the needle plate or endanger the safety of equipment maintenance personnel
