Problems solved by technology

The disadvantages of this scheme are: 1) the heald rod is attracted by electromagnetic force to stop and hang on the hook, the heald rod and the magnetic pole piece are not in contact, and there is a magnetic gap between the two, which causes the current to activate the cylindrical coil Larger, the coil temperature rises; 2) After the coil is powered off, the coil and the pole piece have residual magnetism, which will affect the further improvement of the weaving speed; 3) Frequent bending of the heald rod will affect its service life

Embodiment 1

[0010] An electronic jacquard yarn selection mechanism, such as figure 1 In the structure shown, the outer boss 1a, the inner boss 1b, the pin shaft 5 and the casing 1 are injection molded into one body, the thickness of the casing 1 is 2mm, the thickness of the swing arm 6 is 1.6mm, and the number of turns of the coil is 4200 turns , the coil resistance is 645 ohms, and the energizing current is 25 mA. When installing, 8 yarn selection units are used as a group, and the thickness of each group along the combination direction is 44.8mm. The yarn selection mechanism is small in size, especially suitable for making large electronic jacquards. machine, such as the jacquard machine with 12288 needles, the number of coil turns of the traditional electronic jacquard machine is not more than 1400 turns, the coil resistance is not more than 150 ohms, and the current is 80 mA.

Embodiment 2

[0012] An electronic jacquard yarn selection mechanism, such as figure 1 In the structure shown, the outer boss 1a, the inner boss 1b, the pin shaft 5 and the casing 1 are injection molded into one body, the thickness of the casing 1 is 2mm, the thickness of the swing arm 6 is 1.6mm, and the number of turns of the coil is 4500 turns , the coil resistance is 675 ohms, and the energizing current is 25 mA.

Abstract

A composite electronic jacquard interceptor includes pin axle, swing arm, spring, guiding block, electromagnet, saw shape slot with convex, hanging hook, and casing. Comparing with current technology, said invention has advantages of 1, simple structure with small arm swing range and high work frequency, 2, no electrostatic interference due to adopting plastic hook, 3, small magnetic gap, 4, energy saving due to the more windings turns and low voltage.

Description

technical field [0001] The invention relates to a double-action electronic jacquard machine, in particular to an electronic jacquard yarn selection mechanism. Background technique [0002] The traditional electronic jacquard yarn selection mechanism, such as CN89107890.8 provides a longitudinal screw rod positioning mechanism for looms, each positioning mechanism includes a bracket part, a pair of cylindrical coils, and a pair of magnetic pole pieces. Both sides of the upper part of the bracket taper toward its upper end, and both sides of the lower part of the bracket taper toward its lower end. There is a turning point between the lower part and the upper part. Grooves are provided on both sides of the upper part of the bracket. Grooves are provided on the upper part of the bracket. There are two openings for arranging the cylindrical coil, and the edges of a pair of pole pieces are respectively installed on the above-mentioned grooves, and the cylindrical coil is fixed on...
