Electronic pattern card

Abstract

An electronic buckle board is a unit controlling jacquard needle, and substitute of buckle board, which is more efficient and costless. The operating principle is using bistable needle valve to switch hole and aporate. On bistable needle valve there is a coil movable 8a and a coil carcass 8, and on the coil carcass there is a stop 8b. Excitation system constructed by permanentmagnet 10 set on iron core is set in different quality tank 3b fixed vertically on the solenoid valve. If electric current is positive, the movable coil and the coil carcass move up, and the stop can't stop needle, so the hole condition form and corresponding longitude is up; if electric current is zinc current, the movable coil and the coil carcass move down, and the stop stop needle, so the aporate condition form and corresponding longitude is down.

Description

technical field [0001] The invention relates to a device for controlling needle selection of a jacquard machine, in particular to an electronic cardboard. [0002] In the traditional mechanical jacquard machine, the device for controlling the needle selection of the jacquard machine is composed of a flower tube, a turning mechanism and a pattern plate. A large amount of cardboard is consumed to manufacture the cardboard used to control the horizontal needle, and the preservation, management and modification of this cardboard are very difficult. From the cardboard to the cardboard, it needs to go through a series of processes such as punching and threading. , this process will consume a lot of time; and the jacquard machine using the pattern plate, because the mechanical parts such as the turning mechanism and the flower tube cannot adapt to the high speed, seriously limits the speed of the jacquard loom. Generally, the traditional jacquard loom cannot exceed 150 shuttles per ...

Problems solved by technology

It can be seen from the analysis that the electromagnet is a solenoid electromagnet. The disadvantage of this type of electromagnet is that the residual magnetism is large, so the reaction speed is low. On the other hand, an additional reset coil is required to quickly reset the moving iron core

This complicates the structure of the electromagnet. During actual work, the temperature of the electromagnet rises, and high operating temperature will seriously affect the service life of the electromagnet; on the other hand, all its electromagnets are fixed on the same On the chassis, the push bar is also placed on the same reset board. So many electromagnets and bar are fixed together densely, which is very important in the actual production, debugging, installation and maintenance of electronic flower boards. are difficult
