Electronic needle selection mechanism for jacquard machine

Abstract

The invention discloses an electronic cylinder provided with a valve seat frame and a push pin frame, all electromagnetic valve plates for fixing electromagnetic valves are arranged in the valve seat frame, the push pin frame is positioned below the valve seat frame and constructed by a stair descending plate and a push pin frame, the stair descending plate is provided with plural rows of push pin baffle plates, and the push pin frame and the restoring plate are integrated as a whole. Relative to the push pins, the valve seat frame can move to and fro in the horizontal direction and the vertical direction, and the push pin frame can move to and fro in the horizontal direction. Each electromagnetic valve is provided with two armature pins, porose or aporate situation is shaped by whether the armature pins cover the push pin baffle plate through pores, and the work is done. The invention replaces the restoring coils or permanent magnet with the mechanical restoring mode, thus, on the one hand, eliminating residual magnetism and resolving the problem of electromagnetic valve damage caused by easy breakage of the connecting wires of the working coils; on the other hand, resolving the problem of likely tremble of the hanging push pins under the combined action of the push pin frame and the push pin baffle plate after adopting the integral push pin structure, to enhance the adaptability of the push pins and the transverse pins.

Description

【Technical field】 [0001] The invention relates to an electronic jacquard machine, in particular to an electronic fountain used in matching with the electronic jacquard machine. 【Background technique】 [0002] The emergence of electronic fountains (or electronic pattern boards, electronic pattern boards, etc.) has changed the way that traditional mechanical jacquard machines rely on the needle selection mechanism composed of mechanical fountains, turning mechanisms and pattern plates to select needles, realizing time-saving and material-saving. The purpose of high efficiency. The "electronic flower board" of Chinese Patent No. 012394505 (hereinafter referred to as "Patent 1") is an electronic flower tube, which utilizes the original frame, handle, vertical needle, and horizontal needle mechanism of the mechanical jacquard machine in the traditional jacquard machine. By replacing the mechanical embossed pattern with electronic pattern, only a small amount of capital is needed...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned known technology has the following problems: Patent 1 adopts the working coil and reset coil to pass through the moving iron core to form a "no hole" or "hole" state, and controls the horizontal needle to realize the shed, with large residual magnetism and complex structure

Thus there are problems: 1. In work, because the coil lead wire needs to be in the state of reciprocating movement for a long time, although the flexible circuit (connecting wire) is used, the coil lead wire is still prone to breakage, and the reliability is poor

2. The stopper that interacts with the push pin is directly connected to the coil. Under the action of the push pin, it will affect the relative position of the working coil, which will cause damage to the solenoid valve, affect the work of the entire electronic fountain, and have poor reliability.

In addition, generally speaking, the push needle that cooperates with the horizontal needle is in a suspended state relative to the solenoid valve that reciprocates left and right after coming out of the reset plate to the working end, so it is easy to vibrate and affect the operation accuracy
