Description

Technical Field

[0001] This utility model relates to the field of jacquard machines, and in particular to a high-speed, wear-resistant component for an M5 jacquard machine. Background Technology

[0002] Jacquard machines utilize the attraction force of electromagnets and the pressure of springs to achieve the reciprocating motion of a moving iron. In existing jacquard machine components, each time the moving iron is attracted by the electromagnet, it collides with the electromagnet's attracting end, producing fine iron powder with each collision. This is especially pronounced under high-speed operation. Over time, both the moving iron and the electromagnet's attracting end wear down, resulting in a short lifespan for both. To address these issues, a solution is proposed below. Utility Model Content

[0003] The purpose of this invention is to provide a high-speed, wear-resistant M5 jacquard machine component that has the advantages of being resistant to wear under high-speed operating conditions and having a long service life.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A high-speed, wear-resistant M5 jacquard machine assembly includes a clamping plate and an electromagnetic structure disposed on one side of the clamping plate. The electromagnetic structure comprises an electromagnet, a return spring, and a moving iron. The moving iron includes a moving iron attraction end matched with the electromagnet, a hook end away from the moving iron attraction end, and a rotating part located between the moving iron attraction end and the hook end. A rotating shaft is disposed on the upper surface of the clamping plate, and the rotating part and the rotating shaft are rotatably connected. Positioning protrusions are provided between the moving iron attraction ends and the rotating parts of both moving irons. Two clamping plates are disposed at corresponding positions on the clamping plate. One end of the return spring is sleeved on the positioning protrusion, and the other end of the return spring abuts against one side of the clamping plate. The electromagnet includes a longitudinal iron core and electromagnet attraction ends located on both sides above the iron core. The positions of the electromagnet attraction ends and the moving iron attraction ends correspond. A plastic sleeve is sleeved on the electromagnet attraction end, and the length of the plastic sleeve is greater than the length of the moving iron attraction end.

[0005] The beneficial effects of this utility model are as follows: the plastic sleeve fitted on the electromagnet attraction end is made of soft material. When the moving iron attraction end is attracted by the electromagnet attraction end and moves closer to it, the side of the plastic sleeve protruding outward will push against the moving iron attraction end, preventing the electromagnet attraction end from making hard contact with the moving iron attraction end, thereby reducing the wear of the electromagnet attraction end and the moving iron attraction end. Because a plastic sleeve is fitted on the electromagnet's attraction end, the iron core is lengthened to prevent insufficient magnetic force between the electromagnet's attraction end and the moving iron's attraction end. This increases the number of turns in the electromagnet coil, enabling the electromagnet to generate a greater magnetic force. As a result, even after being weakened by the plastic sleeve, the magnetic force generated by the electromagnet's attraction end can still generate sufficient attraction force on the moving iron's attraction end, allowing the electromagnetic device to function normally.

All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0009] like Figures 1 to 4 As shown, a high-speed, wear-resistant M5 jacquard machine assembly includes a clamping plate 1 and an electromagnetic structure disposed on one side of the clamping plate 1. The electromagnetic structure includes an electromagnet 2, a return spring 3, and moving irons 4. The core of the electromagnetic structure is the electromagnet 2, which consists of a longitudinally arranged iron core 11 and two electromagnet attraction ends 12 located on both sides above the iron core 11. The two moving irons 4 are rotatably connected to a rotating shaft 8 fixed to the upper surface of the clamping plate 1 via their rotating parts 7, allowing each moving iron 4 to swing around the rotating shaft 8. Each moving iron 4 includes a moving iron attraction end 5 that matches the position of the corresponding electromagnet attraction end 12, and a hook end 6 located away from the moving iron attraction end 5 for performing jacquard movements.

[0010] A positioning protrusion 9 is provided between the moving iron attraction end 5 of the moving iron 4 and the rotating part 7. Two clamping plates 10 are fixedly installed on the clamping plate 1, corresponding to the positions of these two positioning protrusions 9. Each of the two clamping plates 10 has a groove machined on its opposite side. One end of the return spring 3 is sleeved on the positioning protrusion 9 of the moving iron 4, and the other end is inserted into the groove of the clamping plate 10, thereby providing a return force to the moving iron 4.

[0011] Each electromagnet attraction end 12 is tightly fitted with a plastic sleeve 13 made of a soft material, such as rubber. The length of this plastic sleeve 13 is greater than the length of the moving iron attraction end 5 of the moving iron 4, ensuring that the plastic sleeve 13 contacts the moving iron attraction end 5 first when the magnet is attracted, thereby completely avoiding direct hard contact and wear between the electromagnet attraction end 12 and the moving iron attraction end 5.

[0012] To protect the internal moving parts from the intrusion of floating fibers and dust, the clamping plate 1 is provided with a ring-shaped upper sealing rib 14, with the rotating shaft 8 located at the center of this sealing rib. The upper sealing rib 14 has a front opening 15 on its front side, allowing the moving iron 4's attracting end 5 to extend and interact with the electromagnet 2; and a rear opening 16 on its rear side, allowing the hook end 6 of the moving iron 4 to pass through and perform its function. Furthermore, a bottom sealing rib 17 is fixed to the surface of the clamping plate 1. The middle of this sealing rib is curved downwards, and the curve of its upper end face is precisely designed to fit tightly against the lowest curve of the electromagnet 2's core 11, forming an effective seal and achieving positioning of the electromagnet 2.

[0013] Finally, the upper part of the core 11 of the electromagnet 2 is precisely positioned between two clamping plates 10. The two clamping plates 10 hold and restrict its position, ensuring the stability and installation accuracy of the entire electromagnet 2 during operation.

[0014] It is worth noting that, since a plastic sleeve 13 is fitted on the electromagnet attraction end 12, in order to prevent insufficient magnetic force of the electromagnet attraction end 12 on the moving iron attraction end 5, the iron core part 11 is lengthened, and the number of turns of the electromagnet 2 coil is increased, so that the electromagnet 2 can generate a greater magnetic force. Thus, even after the magnetic force generated by the electromagnet attraction end 12 is weakened by the plastic sleeve 13, it can still generate sufficient attraction on the moving iron attraction end 5, so that the electromagnetic device can work normally.

[0015] After the portion of the plastic sleeve 13 that protrudes above the end face of the electromagnet attraction end 12 is completely worn out, each time the moving iron attraction end 5 contacts the electromagnet attraction end 12, it will simultaneously contact the plastic sleeve 13 and the electromagnet attraction end 12, so that the wear rate of the electromagnet attraction end 12 is still lower than the wear rate of the electromagnet in the existing design without the plastic sleeve 13.

[0016] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
