Abstract
The utility model discloses a knife forging type electromagnetic keeping needle selecting device, belongs to the technical field of the textile machinery and comprises a shell body; wherein, the shell body is provided with a plurality of groups of needle selecting units, each of which comprises a needle selecting knife blade which comprises a knife head with rakes at both sides thereof and perforated projections at both ends; a magnetic sleeve and permanent magnetic steel are positioned on the knife blade and a bar magnet and the magnetic steel are arranged in the shell body by one-by-one correspondence; the bar magnet is coated by an electromagnetic coil; a circuit board is positioned at one end of the shell body; a spring is arranged between the electromagnetic coil and the circuit board; the electromagnetic coil is fixed on a wire wrapping caliper which is fixedly connected with a side plate through the spring; a lead wire of the electromagnetic coil is welded on the circuit board. The needle selecting device is characterized by sound structure and high working efficiency with the knife forging type electromagnetic keeping.
Description
Technical field
The utility model relates to a kind of textile machine, is meant that especially a kind of formula electromagnetism of forging a knife keeps needle selecting device.
Background technology
Existing needle selecting device generally all adopts the fencing type electromagnetism to keep, the action of its cutter head is to control a permanent magnet that is installed on the cutter head by coil electricity, behind the coil electricity, the N utmost point and the S utmost point have just been produced at two of coil, the principle that the same sex according to magnetic is repelled each other, there is a natural attraction between the sexes, change the N utmost point and the S utmost point of coil by the energising direction of coil, thereby control moving up and down of cutter head.The shortcoming of this needle selecting device is: 1, adopt the fencing type design, the cutter head inefficiency; 2,, cause cutter head work not listen instruction and make mistakes because magnetic interference.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide a kind of formula of forging a knife electromagnetism simple in structure, operating efficiency to keep needle selecting device.
The technical scheme that the utility model is taked for achieving the above object is, a kind of formula electromagnetism of forging a knife keeps needle selecting device, comprise by skeleton 4, cover plate 3, the housing 14 that side panel 11 is formed, be installed in some groups of needle selection unit on the housing 14,8 groups of preferred employings, each needle selection unit comprises needle selection blade 1, be installed in magnetosheath 5 and permanent magnet steel 6 on the blade 1, bar magnet 9 is with magnet steel 6 and is arranged on one to one in the housing 14, on bar magnet 9, be coated with solenoid 8, circuit board 12 is installed in an end of housing 14, spring 10 is installed between solenoid 8 and the circuit board 12, solenoid 8 is by on the spring 10 fixing online bag clamps 7, line bag clamp 7 is fixed on the side panel 11, and the wire bonds of solenoid 8 is on circuit board 12.
Described needle selection blade 1 comprises that both sides have the projection with holes 13 at the cutter head 15 of gradient, blade 1 two ends, projection 13 is to form by a part of bending 90 degree back perforation of blade lower body, pass projection 13 with on blade 1 stationary housing 14 by pin rod 2, offer the opening suitable with cutter head 15 on cover plate 3, blade 1 is that the center swings with the hole; The amplitude of fluctuation of cutter head 15 is by cover plate 3 controls.
The beneficial effects of the utility model are as follows:
1, cutter head is boxed out in the middle of adopting unique texture: A, blade, alleviates cutter head weight, makes the blade flexible swinging; B, blade adopt the both sides gradient, are convenient to needle selection device two-way operation back and forth; Perforation after 90 ° of a part of bendings of C, blade lower body, it is fixing to be used for the pin rod, and blade is that the center swings with the hole; Because blade needle selection impact is bigger during the work of needle selection device, can make blade keep suitable intensity can keep certain swing speed and design blade like this.2, the utility model magnet steel external application magnetosheath is wrapped, and magnet steel and magnetosheath form the loop mutually makes the magnet steel magnetic line of force not to external diffusion, avoids the magnetic line of force between adjacent magnet steel to disturb, and guarantees that the action of blade does not make mistakes when running up; 3, this structure bar magnet adopts the Fe-Cr-Co deformable permanent magnetic alloy, and like this, when the direction of the winding current changed, the N utmost point of bar magnet and the exchange of the S utmost point also can be caught up with synchronously, keeps the works fine state thereby the needle selection device is run up.

The specific embodiment
As shown in Figure 1, the utility model comprises by skeleton 4, cover plate 3, the housing 14 that side panel 11 is formed, be installed in some groups of needle selection unit on the housing 14, present embodiment is preferably 8 groups, each needle selection unit comprises needle selection blade 1, be installed in magnetosheath 5 and permanent magnet steel 6 on the blade 1, bar magnet 9 is with magnet steel 6 and is arranged on one to one in the housing 14, in conjunction with shown in Figure 4, on bar magnet 9, be coated with solenoid 8, circuit board 12 is installed in an end of housing 14, spring 10 is installed between solenoid 8 and the circuit board 12, solenoid 8 is by on the spring 10 fixing online bag clamps 7, line bag clamp 7 is fixed on the side panel 11, and the wire bonds of solenoid 8 is on circuit board 12.
With reference to Fig. 2 and shown in Figure 3, needle selection blade 1 comprises that both sides have the projection with holes 13 at the cutter head 15 of gradient, blade 1 two ends, projection 13 is to form by a part of bending 90 degree back perforation of blade lower body, pass projection 13 with on blade 1 stationary housing 14 by pin rod 2, offer the opening suitable with cutter head 15 on cover plate 3, blade 1 is that the center swings with the hole; The amplitude of fluctuation of cutter head 15 is by cover plate 3 controls.
The utility model adopts the formula electromagnetism of forging a knife to keep, and the magnet steel that is attached on the needle selection blade is controlled in the magnetic field that is produced by coil electricity, and a utmost point of magnet steel (N or the S utmost point) behind the coil electricity, has just produced the N utmost point, the S utmost point at two of coil near the bar magnet in the coil; After the electrical current direction changes, the N utmost point at bar magnet two ends, S very much also change thereupon, according to the same sex of the magnetic principle that there is a natural attraction between the sexes of repelling each other, the side-to-side movement of blade just can be controlled by the sense of current of coil, in actual use, the electric current change frequency of coil is high more, and swinging of blade is also fast more, otherwise just slow more.The utlity model has the characteristics of structure, high efficiency.
