Needling plate pneumatic locking device of needle loom

Abstract

This invention discloses a needle-punching machine's planting needle board air operated locking arrangement. Its characteristics: including two glide organization install on the portable beam, two lift hook uses in connecting the portable beam ledger wall and planting needle board, as well as two aerocyst can cause to plant the needle board automatic positioning on the portable beam ledger wall; The two lift hook's upside connect with a glide organization slip, two lift hook's middle is located at the portable beam ledger wall and planting needle board's both sides separately to form the about lift hook. The about lift hook's terminal bend inside tocancel the planting needle board's both sides, between the about lift hook and the portable beam ledger wall's surface forms two cavities; The above two aerocysts are located in separately the above two cavities, on the aerocyst is equipped with air faucet uses to connect air source. This invention to installment and the disassemblage planting needle board is convenience and quickly, and the planting needle board and the portable beam ledger wall is connected between surface contact, therefore planting needle board is evenly stress, planting needle board not to be easy to distort curving, thus the thorn needle is not easy to break off.

Description

technical field [0001] The invention relates to a locking device for a needle planting plate of an acupuncture machine, more specifically, to a pneumatic locking device for a needle planting plate of an acupuncture machine. Background technique [0002] In the existing acupuncture machines, the needle planting plate is generally fixedly installed on the base plate of the movable beam bottom plate. During the up and down movement of the needle planting board, the thorns on the needle planting board perform needle entanglement on the fiber web passing under it, thereby processing it into a non-woven fabric. [0003] Bolts are generally used to fix the connection between the needle planting plate and the movable beam bottom plate of the existing acupuncture machines, because the connection between the needle planting plate and the movable beam bottom plate is point contact, so the needle planting plate is stressed during the working process. Uneven, easily deformed and bent, c...

Problems solved by technology

[0003] Bolts are generally used to fix the connection between the needle planting plate and the movable beam bottom plate of the existing acupuncture machines, because the connection between the needle planting plate and the movable beam bottom plate is point contact, so the needle planting plate is stressed during the working process. Uneven, easily deformed and bent, causing the needles to break; when the needles are broken, the needle planting plate needs to be disassembled to replace the needles, and after the needles are replaced, the needle planting plate must be installed on the movable beam bottom plate. It is time-consuming and labor-intensive to remove the bolts used for fixing one by one. Therefore, the installation and disassembly of the needle planting plate is cumbersome, which brings great inconvenience to the maintenance of the machine
