Abstract
AnThe utility model relates to an electronic jacquard-weaving needle-selection mechanism. The utility model is characterized in that the needle-selection mechanism is provided with an electromagnetic valve 2 and 2', and a hook 3 and 3'. The electromagnetic valve 2 is composed of an outer shell 21, a coil 22, a pendulum rod 23 and a permanent magnet 24. The hook 3 is installed on a casing 1 through a pin, and kinematic pair connection is adopted between the pendulum rod 23 and hook 3. The electromagnetic valve 2' and hook 3' are positioned below the hook 3, and their structure and installation methods are same as the electromagnetic valve 2 and hook 3. Compared with existing technologies, the utility model has advantage that adopting this needle-selection mechanism can enhance weaving speed of the jacquard loom by a large margin, namely enhancing loom production efficiency, and simultaneously it can obviously degrade electricity consumption with reliable running.
Description
The utility model relates to a kind of single-lift jacquard, particularly a kind of electronic jacquard selecting mechanism.
Existing electronic jacquard selecting mechanism, the used selecting mechanism of broadcloth electronic jacquard machine as the Britain Bonus machinery Bonas MachineCompany Ltd. of Co., Ltd design, be a kind of two steel lifting-hooks handling by an electromagnetic valve, lifting-hook connects warp thread by pulley and rope, lifting-hook is shelved on respectively and griffes, and follow and griffe to pump, when the coil electricity of electromagnetic valve, first lifting-hook and griffe to rise, stopping hanging over first to this lifting-hook links up with, follow another lifting-hook and griffe and rise, warp thread is raised, and forms shed open.The defective of this selecting mechanism is to overcome the influence that electromagnetic valve outage back remanent magnetism produces, the further raising of remanent magnetism meeting delayed management restriction loom weaving speed, the electric current of electromagnetic valve coil energising simultaneously is bigger, and the electronic jacquard machine complete machine is provided with thousands of selecting mechanisms, and the energy consumption of complete machine is bigger.
The purpose of this utility model provides a kind of electronic jacquard selecting mechanism of novelty, can overcome the influence of electromagnetic valve outage back remanent magnetism, and reduce the electronic jacquard machine power consumption, use this selecting mechanism, can significantly improve the weaving speed of loom, enhance productivity, can reduce the power consumption of loom again.
A kind of electronic jacquard selecting mechanism, comprise housing, electromagnetic valve, hook, griffe, lifting-hook, it is characterized in that this selecting mechanism be provided with electromagnetic valve 2 and 2 ' and the hook 3 and 3 ', electromagnetic valve 2 is made up of shell 21, coil 22, fork 23, permanent magnet 24, shell 21 is fixed on the housing 1, and fork 23 upper ends are installed on the shell 21 by bearing pin, and permanent magnet 24 is arranged in a side of coil 22 bottoms, hook 3 is installed on the housing 1 by bearing pin, and the employing kinematic pair is connected between fork 23 bottoms and the hook 3; Electromagnetic valve 2 ' and hook 3 ' being positioned at the below of hook 3, its structure and mounting means are identical with hook 3 with electromagnetic valve 2.Under situation about resetting, fork 23 and 23 ' be subjected to respectively permanent magnet 24 and 24 ' attraction, rest in respectively permanent magnet 24 and 24 ' a side, when coil 22 and 22 ' energising, at the inboard place of permanent magnet, coil magnetic field polarity is identical with permanent-magnetic field polarity and repel each other, fork 23 and 23 ' swing to opposite side, hook 3 and 3 ' the coupler body left side and the right side of stretching out housing 1 respectively, hook the lifting-hook 5 and 5 of rising ', form shed open.
With the prior art comparison, advantage of the present utility model utilizes permanent magnet to overcome the electromagnetic valve outage adverse effect of remanent magnetism afterwards, helps accelerating the weaving speed of loom, enhances productivity, and reduces the coil electricity electric current simultaneously, saves power consumption.
Fig. 1 is the structural representation of this electronic jacquard selecting mechanism.
Fig. 2 is the lifting-hook structure chart, and 51 is hanging hole among the figure.
Embodiment:
A kind of electronic jacquard selecting mechanism, its structure as shown in Figure 1, electromagnetic valve 2 is made up of shell 21, coil 22, fork 23, permanent magnet 24, electromagnetic valve 2 ' by shell 21 ', coil 22 ', fork 23 ', permanent magnet 24 ' form, coil 22,22 ' serial connection, each coil turn is 5000 circles, serial connection back operating current is 20mA, and the pendulum angle of fork is 4 °, and the hook pendulum angle is 30 °, griffing stroke is 150mm, per minute reciprocating motion 1000 times.
