Detachable needling structure, flat needling module and special-shaped needling machine

Abstract

The invention provides a detachable needling structure which comprises a needle beam and a needle plate with needles, and is characterized in that an electromagnetic device is arranged in the needle beam, when the electromagnetic device is in a power-on state, the needle beam and the needle plate are electromagnetically attracted, and a position controller is installed on one side wall of the needle beam to clamp and position the needle plate; wherein the sum of the wall thickness of the needle beam and the wall thickness of the needle plate is matched with the height of the open slot of the position controller. An electromagnetic device capable of adjusting the magnetizing quantity is preset in the needle beam, so that constant time and constant control is realized, and the actual requirements of complex working conditions are met; and the position controller is arranged, so that quick and accurate positioning can be realized, manual participation is avoided, particularly, the needle plate is clamped, one-key opening and closing are realized, the disassembly and replacement are convenient, the production efficiency is remarkably improved, and the requirements of batch industrial production are met.

Description

technical field [0001] The invention relates to the field of acupuncture technology, in particular to a detachable acupuncture, a flat acupuncture module, and a special-shaped acupuncture machine. Background technique [0002] Needle-punched three-dimensional fabrics are divided into plane needle-punched prefabricated parts and needle-punched special-shaped components according to their structure. The existing plane needle-punched technology has been generally mechanized, but the needle board and the needle board beam are usually connected by bolts, which is inconvenient to install and disassemble. Flat-plate acupuncture needle boards are long and heavy. During use, the needle boards are unevenly stressed, unstable, and easily deformed. There is a constant and uncontrollable air pressure, which does not meet the molding requirements of complex processes; and the existing positioning methods either adopt manual positioning, which is not accurate enough and the efficiency is n...

Problems solved by technology

[0002] Needle-punched three-dimensional fabrics are divided into plane needle-punched prefabricated parts and needle-punched special-shaped components according to their structure. The existing plane needle-punched technology has been generally mechanized, but the needle board and the needle board beam are usually connected by bolts, which is inconvenient to install and disassemble. Flat-plate acupuncture needle boards are long and heavy. During use, the needle boards are unevenly stressed, unstable, and easily deformed. There is a constant and uncontrollable air pressure, which does not meet the molding requirements of complex processes; and the existing positioning methods either adopt manual positioning, which is not accurate enough and the efficiency is not high; or requires guide rod positioning, which is complicated to operate and low in efficiency, which is not conducive to mass production.

[0003] For special-shaped components, such as rotary prefabricated parts, flat needle punching technology can only be applied to the cylinder part, and it is difficult to apply large needle board forming to the closed end, because the needle punching of large needle boards is circumferentially distributed. The needle-punching trajectory will lead to the breakage of the end; therefore, in the prior art, the end part can only be formed by hand-punching or robotic needle-punching, and then combined with the large-scale needle plate to form the cylinder part for step-by-step production

The needle punching efficiency of manual needle punching or mechanical needle punching is low, and when needle punching at high speed, it is easy to form debris and affect the fabric forming; among them, it is even more unfavorable that it is difficult for the operator to strictly control the needle punching of each layer Strength and uniformity, resulting in unstable internal quality and poor product quality reproducibility
