Description

Electromagnet assembly testing device of electronic jacquard machine

Technical Field

The invention belongs to the technical field of special testing devices for electronic and electrical components of textile machinery, and particularly relates to a testing device for an electromagnet assembly of an electronic jacquard machine.

Background

The aforementioned electromagnet assemblies are also referred to as solenoid valve assemblies, and are found in published chinese patent documents such as CN101718019a (jacquard electromagnet assembly), CN105821553A (jacquard solenoid valve assembly), CN101845698B (a new electronic jacquard solenoid valve assembly), CN102634900a (electronic jacquard solenoid valve assembly), and CN105155076a (electronic jacquard solenoid valve assembly), among others.

The electronic jacquard is matched with a weaving machine, and has the advantages of strong adaptability to fabric change, capability of meeting the requirement of weaving complex fabrics by the weaving machine and good promotion of fabric grade and added value, so that the electronic jacquard is rapidly developed and has good prospects in recent years.

The electromagnetic valve assembly is a critical actuator (also called "actuator") in an automatic jacquard weaving system, because it can convert the electrical signals representing the fabric pattern into the lifting motion of the corresponding warp yarns of the loom during operation. Since hundreds of electromagnet assemblies are needed for one electronic jacquard machine, the quality reliability of the electronic jacquard machine directly affects the quality of the fabric and the weaving efficiency of the loom.

In order to ensure the reliability of the electromagnet assemblies of electronic jacquard machines in service, manufacturers generally need to test the electrical performance parameters, such as resistance, inductance, electromagnetic attraction, etc., because these electrical performance parameters can basically reflect the actual performance of the electronic jacquard machines, so that the failure can be solved as far as possible before the electronic jacquard machine products leave the factory.

At present, the test of the electromagnet assembly is judged according to the action state after the electromagnet assembly is installed (installed on an electronic jacquard), and a further dynamic test after the electronic jacquard is matched with a weaving machine shows that the real and reliable quality of the electromagnet assembly cannot be reflected by the judgment result of the working state after the electromagnet assembly is installed on the electronic jacquard.

The published chinese patent literature shows technical information about the testing of electromagnet assemblies, and typically, the "multi-path electromagnet real-time rapid detection device" recommended by CN100487478C is not meaningful for reference because the structure of the electromagnet aimed by the patent is very different from that of the electromagnet assembly of the electronic jacquard machine.

Before the test, the lifting motor 43 of the structural system of the lifting stroke control mechanism 4, the fixing seat driving motor 55 of the structural system of the component signal suction arm pressing and releasing mechanism 5, and the push plate driving motor 62 of the structural system of the component traction rope hook clamping and releasing mechanism 6 are all at the zero point position in the energized state, and are specifically controlled by the fixing seat position signal collector 54. Then, the tester operates the operation interface of the electrical control box 8, for example, presses a "start test" button to start the automatic test or enter an automatic test state. Then, the left eight (8) ways are tested, at this time, the push plate driving motor 62 of the one of the two component pulling rope hook clamping and pressing and releasing mechanisms 6 located on the left side is operated, and according to the above description of the applicant, the push plate pressing block 652 of the push plate 65 is brought to a specified position, that is, a position where the pulling rope hook flange 722 (the pulling rope hook flange 722 may also be referred to as a "knife lifting foot") on the lower portion of the component pulling rope hook 72 illustrated in fig. 2 is in contact with the component pulling rope hook 72 and the component pulling rope hook 72 is pushed by the pulling rope hook flange 722, specifically, if the position state illustrated in fig. 1 is taken as an example, the component pulling rope hook 72 is pushed backward by the push plate pressing block 652 of the push plate 65, and if the position state illustrated in fig. 2 is taken as an example, the component pulling rope hook 72 is pushed upward by the push plate pressing block 652 of the push plate 65, so that the hook head 721 is separated from the signal suction arm hooking head 711 of the signal suction arm 71, and the suction effect is achieved.

At this time, the left component signal suction arm pressing and releasing mechanism 5 operates the fixing base driving motor 55, and the suction foot 712 of the signal suction arm 71 is separated from the electromagnet 752 according to the above description of the applicant until the sensor contact 591 pushes (abuts) the signal suction arm hook 711 of the left one signal suction arm 71, and the force obtained at this time is the maximum suction force and the component signal suction arm pressing and releasing sensor 59 feeds back the maximum suction force signal to the electric control box 8, and the maximum suction force value of the electromagnet 752 is displayed by the screen of the operation interface of the electric control box 8. Further, the sensor contact 591 is separated from the signal suction arm hook 711 by the reverse operation of the left fixed base driving motor 55, thereby completing the test of the first path of the left eight paths of the electro-magnet assembly 7 of the electronic jacquard machine. It should be noted that: after each path of test, the lifting motor 43 of the lifting stroke control mechanism 4 works once, so that the component signal suction arm presses and releases the mechanism 5 to move downwards by the thickness degree of one (also called one) electromagnet component 7 of the electronic jacquard machine.
