Abstract
The utility model relates to a two-way composite electromagnetic needle selector. The needle selector is characterized in that the needle selector is composed of a bracket 1, an electromagnetical assembly 2, two clamp plates 3 and two jacquard needles 4. The electromagnetical assembly 2 comprises a conducting strip 21, a coil 22, a magnetic isolation belt 23, a magnetic conductive plate 24, an air gap pd 25 and connecting lines. The magnetic isolation belt 23 is a clearance with S-shaped facade and it divides the coil into two groups which work independently. Compared with existing techniques, the scheme has advantages that (1) each needle selector contains two jacquard needles, compact structure and small space usage; (2) besides the jacquard needles, other parts of the needle selector are fixed and motionless, which brings great convenience for installation and maintenance; (3) the structure of electronic jacquard machine which adopts this needle selector is greatly simplified, and the components are reduced and the manufacturing cost of a complete machine can be degraded above 60%.
Description
The utility model relates to a kind of single-lift jacquard, particularly a kind of composite two-way electromagnetic needle selector.
Existing electromagnetic needle selector, the used electromagnetic needle selector of broadcloth electronic jacquard machine as the Britain Bonus machinery Bonas Machine Compa-ny Ltd. of Co., Ltd design, be a kind of by two steel lifting-hooks of each electromagnetic valve manipulation, lifting-hook is connected warp thread by pulley with rope, lifting-hook rests griffes, and follow and griffe to pump, when electronic impulse triggers electromagnetic valve, first lifting-hook and griffe to rise, rest on the hook to this lifting-hook, follow another lifting-hook and griffe and rise, warp thread just is raised, and forms shed open.The defective of this scheme is that each electromagnetic valve must dispose two lifting-hooks and two and griffes just can make a warp thread to mention, and causes the electronic jacquard machine volume bigger thus, and parts increase, and cost an arm and a leg.The jacquard control of Chinese patent CN98121962.4 electronic jacquard machine is made of lifter plate, electromagnet, knitting needle, control panel, crochet hook, guide post, crane, crochet hook mounting, lifter plate and crochet hook mounting pump, electromagnet is fixed on the lifter plate, control panel is made traverse motion, crochet hook is by the guide post clamping, when electromagnet is switched on, corresponding knitting needle is raised, obviously, the required parts of this jacquard control are a lot of, structure is too complicated, and cost is higher relatively.
The purpose of this utility model is to provide a kind of composite two-way electromagnetic needle selector, two knitting needles of each needle selection device configuration, and compact conformation, it is little to take up room, and adopts the electronic jacquard machine volume of this needle selection device less, and manufacturing cost reduces significantly.
A kind of composite two-way electromagnetic needle selector, it is characterized in that this needle selection device is by a support 1, an electromagnetic assembly 2, two clamping plates 3, two knitting needles 4 constitute, support 1 is fixed on the frame of electronic jacquard machine, electromagnetic assembly 2 is by conducting strip 21, coil 22, magnetic isolating plate 23, magnetic conduction sheet 24, antifreeze plate 25 and connecting line are formed, the magnetic isolating plate 23 that wherein coil 22 is divided into two groups is its positive S-shaped gaps, this gap width is not less than 1mm, the positive pole of two groups of coils meets conducting strip 21a and 21b respectively, negative pole meets conducting strip 21c, two clamping plates 3 is arranged in the both sides of support 1, and two knitting needles 4 are by clamping plate 3 and support 1 clamping; Described knitting needle 4 is a sheet metal, and its upper end has and supplies by the through hole 41 of griffing to promote, and the bottom is provided with the breach 42 that is used to hang plummet.A plurality of needle selection device in-lines are arranged in delegation and clamping, are fixed on again on the frame of electronic jacquard machine, multirow needle selection device is set on an electronic jacquard machine.
With prior art relatively, the utility model has the advantages that: (1) each needle selection device contains two knitting needles, compact conformation, and it is little to take up room; (2) except that knitting needle, the miscellaneous part of needle selection device is fixed, brings great convenience for the installation and the maintenance of needle selection device; (3) adopt the electronic jacquard machine structure of this needle selection device greatly to simplify, the complete machine cost can reduce more than 60%.
