Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1-3, a textile needle seat with adjustable space comprises a placing groove 1, a plurality of barrel bodies 2 which are placed side by side and horizontally arranged are fixedly connected in the placing groove 1, the barrel bodies 2 are made of magnetic shielding materials to avoid the influence between two adjacent barrel bodies 2, electromagnets 3 are fixedly connected at both ends of the barrel bodies 2, a plurality of permanent magnet sliding blocks 4 are arranged between the two electromagnets 3, the direction of magnetic induction lines of the permanent magnet sliding blocks 4 is parallel to the axial direction of the barrel bodies 2, the directions of magnetic poles of the two adjacent permanent magnet sliding blocks 4 are opposite, a strip-shaped opening 5 is arranged at the upper end of each barrel body 2, a needle rod 6 is fixedly connected at the upper end of each permanent magnet sliding block 4, the upper end of each needle rod 6 penetrates through the strip-shaped opening 5 and extends out of the barrel bodies 2, the diameter of each needle rod 6 is the same as the, it is worth mentioning that, the number of permanent magnetism slider 4 is the odd number, and is located the permanent magnetism slider 4 of the centre and the inside wall fixed connection of barrel 2, can make a plurality of permanent magnetism sliders 4 use the permanent magnetism slider 4 of centre as central evenly distributed, plays better regulation effect, and the coil in two electro-magnets 3 is around to opposite.
In this embodiment, because like poles of two adjacent permanent magnetic sliders 4 repel each other, when the magnetic force of the electromagnet 3 is larger, the repulsion between the two adjacent permanent magnetic sliders 4 is larger, and the distance between the two permanent magnetic sliders is smaller, that is, the gap between the needle bars 6 on the needle base is smaller; therefore, the distance between the needle bases can be changed by controlling the current on the electromagnet 3 (the relationship between the electrifying current of the electromagnet and the magnetic force is in direct proportion), and the operation is simple and convenient.
Example 2
As shown in fig. 4 to 6, the present embodiment is different from embodiment 1 in that: a second direct current power supply 8 is fixedly installed in the placing groove 1, the current direction of the second direct current power supply 8 is opposite to that of the first direct current power supply 7, and the first direct current power supply 7 and the second direct current power supply 8 are coupled with the electromagnet 3 through a pulse switch (as shown in fig. 6).
In this embodiment, when starting pulse switch, pulse switch makes a round trip to switch fast between first direct current power supply 7 and second direct current power supply 8, the messenger is located 2 both ends electro-magnet 3's of barrel magnetic poles and constantly changes, thereby make a plurality of permanent magnetism sliders 4 constantly separate and constantly gather together again, in-process that pulse switch high frequency switches, make the distance between the adjacent needle bar 6 constantly change, make adnexed broken string or fibre etc. between the needle bar 6 pulled not hard up, even pulled apart, thereby reduced the clearance degree of difficulty to needle bar 6.
Example 3
As shown in fig. 7 to 8, the present embodiment is different from embodiment 2 in that: fixedly connected with elasticity seal membrane 9 between two adjacent permanent magnet slider 4, the lateral wall of two adjacent permanent magnet slider 4, elasticity seal membrane 9 and barrel 2 has formed airtight space jointly, is equipped with one-way gas vent 10 on the elasticity seal membrane 9, is equipped with a plurality of one-way air inlets 11 on the lateral wall of barrel 2, is equipped with the scavenge port 12 with outside intercommunication on the lateral wall of standing groove 1.
In this embodiment, when the pulse switch is turned on and the permanent magnet slider 4 is moved continuously, the enclosed space is enlarged and reduced continuously, and the above operation is repeated, so that the air suction and blowing functions can be performed under the action of the one-way air inlet 11 and the one-way air outlet 10, and not only the air below can be drawn away to cool the first dc power supply 7 and the second dc power supply 8, but also the pulse-type discharged air can blow the fibers between the two adjacent needle bars 6, thereby further performing the self-cleaning function.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
