Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic valve equipment of a jacquard machine, in particular to an electromagnetic valve component of a jacquard machine. Background Art

[0002] The solenoid valve assembly is the core component of the electronic needle selector (such as the British Bonas electronic needle selector). Each set of components includes a solenoid valve, two steel hooks located on both sides of the solenoid valve and capable of reciprocating up and down with the lifting knife, and two guide spacers. Each solenoid valve is an integral component formed by two iron cores wound with coils and their magnetic conductive sheets, and the terminal is glued to the insulator. When working, the solenoid valve controls the hooks to connect the warp yarns through pulleys and ropes. The hooks are placed on the lifting knife and reciprocate up and down with the lifting knife. When the solenoid valve is energized, one of the hooks rises to the highest point with the lifting knife and is attracted by the magnetic field. The hook stops and hangs on a hook on the side wall of the solenoid valve, and the other hook and its lifting knife rise, and the relevant warp yarn is lifted to form a shed. During the use of this electronic needle selector solenoid valve, the hooks that slide up and down on both sides cannot accurately achieve the buckle with the hooks in the process of rapid movement by the lifting knife.

[0012] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0013] Embodiment: A solenoid valve assembly of a jacquard machine, such as Figure 1-Figure 2As shown, it includes a valve body and a sliding sheet 1, the valve body includes a shell 2, the left and right side surfaces of the upper end of the shell 2 are vertical planes parallel to each other, the left and right side surfaces of the lower end of the shell 2 are inclined surfaces that are retracted inward at the lower end, and two shielding plates 3 are arranged at the center position inside the shell 2, one of the shielding plates 3 is arranged at the upper end of the shell 2, and the other shielding plate 3 is arranged at the lower end of the shell 2, an upper mounting position 4 is arranged on the inner side surface of the shell 2 on both sides of the upper shielding plate 3, and a lower mounting position 5 is arranged on the inner side surface of the shell 2 on both sides of the lower shielding plate 3, and the two A slot 6 is provided on the side surface of the shell 2 at the lower side of the upper mounting position 4, a compression spring 7 is provided on the inner side of the side surface of the shell 2 at the lower side of the two lower mounting positions 5, two pin shafts 8 are symmetrically provided between the shell 2 between the two shielding plates 3, and a swing core 9 is connected to the two pin shafts 8, and the swing core 9 includes a plug plate 10 located at the top, and the plug plate 10 is arranged in the slot 6. The lower end of the swing core 9 extends to the position of the compression spring 7 and is connected to the end of the compression spring 7, and a coil 11 is provided in the upper mounting position 4 and the lower mounting position 5.

[0014] A slideway 12 is provided on the left and right outer sides of the lower end of the valve body, and the two sliding sheets 1 are slidably connected in the slideway 12. A slot 13 is provided at the upper ends of the two sliding sheets 1 at positions corresponding to the slots 6; a wear-resistant sheet 14 is provided on the outer side of the valve body in the slideway 12; two poles 15 are provided on the top of the shell 2, and the two poles 15 are connected to the coil 11.

[0015] The principle of the utility model is as follows: in the initial position, the two iron cores on the upper side are in a de-energized state, and the two coils 11 on the lower side are in a energized state, thereby generating magnetism to adsorb the two swinging iron cores 9. At this time, the plug 10 in the swinging iron core 9 does not extend out of the slot 6, and the sliding piece 1 can slide up and down on the left and right sides of the valve body. When it is necessary to adsorb and buckle a sliding piece 1, the coil 11 on the lower side of the same side is controlled to lose power, and the magnetic disappearance spring drives the swinging iron core 9 to rotate around the pin 8, and the plug 10 extends out of the slot 6. Due to the lower side of the valve body It is an inclined surface with the lower end contracted inwards, so the sliding piece 1 will not be blocked by the plug plate 10 when sliding up. After the sliding piece 1 slides up to the specified position, the coil 11 on the upper side is energized to generate magnetism, which adsorbs the upper end of the sliding piece 1, so that the slot 13 on the sliding piece 1 is sleeved on the plug plate 10, so that it will not fall down with the sliding of the jacquard machine knife plate. On the contrary, the two coils 11 are controlled to be powered on and off, the coil 11 on the lower side adsorbs the swing core 9, and the coil 11 on the upper side is powered off, and the sliding piece 1 rebounds by its own rigidity, thereby realizing the disengagement of the sliding piece 1 from the plug plate 10.

Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
