Solenoid valves for jacquard

Abstract

The invention relates to solenoid valves for a jacquard, which are improved revolutionarily. Two groups of solenoid coils (3) are arranged in the same valve body (1); the two groups of solenoid coils (3) share an electrode and are in electrical connection with exterior through three contact pins (2) arranged in a neck of the valve body (1) in parallel; each group of solenoid coils (3) are respectively provided with two pick-up surfaces (4) on both sides of the valve body (1); the two pick-up surfaces (4) on the same side are used as a working surface; two vertical needle hooks (5) are arranged at the tail of the valve body (1), so that vertical needles lifted by the jacquard are hooked, and each solenoid valve can control the motion of the two vertical needles simultaneously and independently; magnetic steel (7) is arranged at the tail end of a distance piece, and the vertical needles picked up with the pick-up surfaces (4) can reduce deviation and malfunction under the action of the magnetic steel (7); hooks (9) capable of being in close fit to each other are designed on a cover plate (8), and the cover plate (8) is pressed on the valve body (1) tightly through the hooks (9), so that the cover plate fixes the contact pins (2) and the solenoid coils (3) and prevents dust; and simultaneously, the design method of quick connection can also improve the assembling efficiency of the solenoid valves.

Description

Technical field [0001] The invention relates to a solenoid valve for a jacquard machine, in particular to a solenoid valve with two sets of solenoid coils placed in a valve body and capable of working independently at the same time. Background technique [0002] The solenoid valve of the jacquard machine is used in the electronic jacquard machine. It converts the electrical signal that characterizes the fabric pattern into the lifting motion of the corresponding warp when it is working. It is an extremely key executive element in the automatic jacquard weaving system. [0003] Currently commonly used solenoid valves for jacquard machines generally use two internal coils connected in series and installed in a valve body, and each solenoid valve can only control the movement of one needle. Conventional electronic jacquard machines need to install 2688 needles and 2688 solenoid valves. In this way, the volume of the faucet of the jacquard machine is very large and needs to occupy a r...

Problems solved by technology

It is undoubtedly a huge waste of resources for manufacturers and users of electronic jacquard machines

[0004] Moreover, the electronic jacquard machine only relies on the pull-in of the solenoid valve to move the needle, and it is prone to deviation and misoperation after a certain period of time, resulting in an increase in the scrap rate and a decrease in work efficiency.
