Description
Technical Field
The invention relates to a jacquard machine vertical hook structure and a vertical hook component thereof, in particular to a novel structure of a jacquard machine component driving suction vertical hook, and belongs to the technical field of jacquard machine structures.
Background
With the wide application of electronic jacquard, the number and the output of jacquard components matched with the electronic jacquard are greatly improved. Jacquard assemblies are the main actuators of electronic jacquard machines forming openings, which to a large extent determine the quality, cost and production efficiency of the textile product. In practice, jacquard machines are usually in a long-term operating state. Thus, the performance of the jacquard assembly and its components has a very high impact on the reliability of the whole machine.
The hook is a key part of a jacquard assembly, and the main part of the hook structure of the existing jacquard comprises a hook body, a tongue and a harness cord, and the attraction and release between a moving iron and an electromagnet are realized through the reciprocating motion of the hook structure on a pulley block and the on-off of the electromagnet. In the attracting process, due to the existence of the reed structure, the reed generates elastic tension to be applied to one end of the moving iron, so that the other end of the moving iron can be in close contact with the electromagnet for attracting. Although this contact-type engagement is firm, it also has two main drawbacks of impact wear and release delay. In the contact attraction process of the moving iron and the electromagnet, the moving iron and the electromagnet can collide once after attraction for one time. Such frequent impacts are very demanding with respect to the fatigue resistance and wear resistance of the moving iron and the electromagnet and even of the whole carabiner assembly. The abrasion of other parts of the jacquard assembly can be aggravated for a long time, and the service life of the jacquard assembly and the stability and the reliability of operation are directly influenced. In addition, in the working environment, the contact surface of the moving iron and the electromagnet inevitably adheres with some oily substances and dust, which causes a certain resistance to the release process after the suction, so that the time delay is caused, and the quick release cannot be realized. And once released, the release delay affects the quality of the fabric, causing fabric blemishes.
Disclosure of Invention
The present invention is directed to solving the above-mentioned problems, and further, to provide a new structure hook of a jacquard machine and a new structure hook assembly thereof, which mainly solve two main technical problems of assembly wear and release delay existing in the hooks of the conventional structure. The invention optimizes the structure of the vertical hook, thereby obtaining the novel structure vertical hook of the jacquard, which has excellent fatigue resistance, effectively reduces the abrasion of the jacquard components, prolongs the service life of the jacquard components, and further improves the overall operation reliability of the jacquard.
In order to solve the problems, the invention adopts the following technical scheme:
the novel structure of the jacquard machine hook comprises a hook body, a hook body part, a harness cord connecting part and a lifting knife matching part, wherein the hook body part is positioned on the hook body.
The size, shape, position and precision of the auxiliary suction boss should satisfy: when the upper limit is lifted, an effective non-contact attraction distance is provided between the moving iron and the electromagnet.
The auxiliary suction boss is positioned between the hook body part of the vertical hook body and the lifting knife matching part.
The surface of the auxiliary suction boss is provided with oil grooves which are densely distributed on the surface of the auxiliary suction boss.
The jacquard new structure hook component sequentially comprises an electromagnet, a movable iron and a hook according to the position relation from top to bottom, wherein the hook comprises a hook body, a hook body part, a harness cord connecting part and a knife matching part, wherein the hook body part is positioned on the hook body; the special feature is that:
the auxiliary suction boss is arranged on one side of the vertical hook body in a protruding mode and is of a rigid structure.
The size, shape, position and precision of the auxiliary suction boss should satisfy: when the upper limit is lifted, an effective non-contact attraction distance is provided between the moving iron and the electromagnet.
The auxiliary suction boss is positioned between the hook body part of the vertical hook body and the lifting knife matching part.
The movable iron comprises a rotary mounting part in the middle, a first rotary arm extending downwards along the rotary mounting part and a second rotary arm extending upwards along the rotary mounting part; the end part of the first rotating arm is provided with a hook part matched with the hook body part of the vertical hook body, and the end part of the second rotating arm is provided with an attraction part matched with the electromagnet in an attraction way.
The movable iron is in rigid contact with the auxiliary suction boss of the vertical hook both in the process of lifting the knife to drive the vertical hook to ascend and in the process of passing the wire to drive the vertical hook to descend;
the matching relation between the vertical hook and the moving iron is as follows: when the vertical hook is lifted, the auxiliary suction boss of the vertical hook applies lateral thrust to the hook part of the movable iron, so that the first rotating arm of the movable iron is far away from the vertical hook, the second rotating arm is close to the electromagnet, and finally, the suction part at the end part of the second rotating arm is kept at an effective non-contact suction distance with the electromagnet.
The novel structure vertical hook of the jacquard machine cancels the tongue spring of the traditional vertical hook, replaces the tongue spring with the auxiliary suction boss, and achieves the aim of auxiliary suction by controlling the position, the size and the precision of the auxiliary suction boss. Because the tongue spring of the traditional vertical hook is in flexible connection with the vertical hook, when the moving iron is in contact with the tongue spring, the tongue spring is in elastic contact with the moving iron, and the elastic force generated by the tongue spring acts on one end of the moving iron, so that the other end of the moving iron is attracted with the electromagnet. In order to achieve the reliability of the attraction, the conventional vertical hook component also considers the problem of elastic failure of the reed in the long-term use process, the elastic force of the reed is designed to be far greater than the expected attraction force at the beginning of the design, and the contact attraction between the moving iron and the electromagnet is converted into the impact attraction, so that the problem of impact abrasion is brought. Therefore, the auxiliary suction boss adopted by the invention overturns the established thought of the traditional vertical hook structure, the flexible contact between the vertical hook and the moving iron is changed into rigid contact through the rigid boss which is arranged on the vertical hook body in a protruding way, the contact mode is easier to control the design of the vertical hook body and the configuration between the vertical hook body and each matching part, the contact force between the auxiliary suction boss of the rigid structure and the moving iron is constant, the adverse effects of fatigue abrasion and the like caused by gradual change of the spring elastic force can be solved, and the most critical is that the moving iron and the electromagnet are always in an effective non-contact suction state through the management and control of the position and size precision of the auxiliary suction boss. The attraction state avoids direct contact between the moving iron and the electromagnet, no impact occurs between the moving iron and the electromagnet, no noise exists, the performance is more stable, meanwhile, the abrasion of other parts of the jacquard machine assembly caused by impact is not aggravated, and the operation reliability and the service life of the jacquard machine are effectively ensured. In addition, because the non-contact attraction state is between moving iron and the electro-magnet, when the electro-magnet outage, move the iron and can respond fast in the first time, move the release process of iron and do not have any resistance, move effective quick release between iron and the electro-magnet, finally fully guaranteed the fabric quality.
