Description
Technical field
The utility model is related to field of textile machinery, more specifically, is a kind of electromagnetic needle selector of small spacing.
Background technology
Slide cam selector used in computer knitting machine is thimble blade to be controlled using the control signal of microcomputor program (or needle selection is prominent
Refer to) motion, reach that lifting or avoids it at jacquard weave faller gill, and then realize the purpose that braiding is required.
Conventional slide cam selector, divides from operating principle, there is two kinds of electromagnetic type and piezoelectric type at present：Piezoelectric needle selector is profit
With piezoceramic material as conversion element, the pulse signal sent using controller is acted on piezoelectric element, by piezoresistive material
The inverse piezoelectric effect of material, makes piezoelectric element bend to the shape remembered in advance to carry out needle selection；Another slide cam selector is then to utilize
Different directions electric current is passed through to electromagnetic solenoid, makes the polarity respective change of electromagnetic solenoid head end, or match somebody with somebody with alnico magnets
Conjunction is used, and is realized that needle selecting knife is swung by the suction and repulsion between electromagnet and alnico magnets, i.e., is realized needle selection with pressing method,
Or slide cam selector needle selection is directly controlled by the change in polarity of electromagnet, knitting needle point is walked different tracks, complete needle selection action.
Two kinds of needle selection modes compare, the characteristics of piezoelectric needle selector has fast response time, heating is few, but in element
It is inferior slightly in terms of stress and protecting against shock, vibrations, easily occur the situation that piezoelectric element loses the memory of, and it is expensive；Electromagnetism
Formula slide cam selector is cheap, and can bear larger power, and vibration resistance is good, and service life is long, therefore wider using face；But by line
Circle body is accumulated and resistance limitation (resistance is small at least for coiling, and power is big, and control circuit board is burnt in easily heating), therefore needle selection on the market
Device classification is general using blade spacing 4mm as boundary, and what it is less than 4mm is all to use piezoelectric ceramic slide cam selector, is lacked at present to small
Away from electromagnetic needle selecting machine design and producing.
Utility model content
Main purpose of the present utility model is that there is provided a kind of electromagnetic separation of small spacing in order to overcome deficiency of the prior art
Pin device.
To achieve these goals, the utility model takes following technical scheme：
A kind of electromagnetic needle selector of small spacing, including the N number of needle selection unit being located in housing, each needle selection unit include band
There are the thimble blade of permanent magnet and the magnet coil with magnetic core, magnet coil periphery is coated with radome, the thimble knife
Spacing between piece is not more than 4mm.
As further improvement of the utility model, a diameter of 6-10mm of the magnet coil, resistance is 1-5 Ω, work
Make voltage for 12V.
As further improvement of the utility model, the control mode of the magnet coil is high current in short-term；Control
Time is 300 to 400 microseconds, and electric current is 6A.
As further improvement of the utility model, the magnet coil is set at before magnetic core 1/3rd.
As further improvement of the utility model, the radome is square；N number of needle selection unit point two rows are close
Arrangement, and make the distance values between the thimble blade be 3.2mm.
As further improvement of the utility model, there is a 2-5 degree between the cutter head and blade of the thimble blade
Slanted angle.
Magnetic used in conventional slide cam selector protects magnet coil, is required to meet that power is big, heating is few etc., can only coil turn around
Many, line footpath changes slightly, therefore resistance, generally in 12 ohms, operating voltage is in 24v to 30v, conduction time be 1 millisecond extremely
Between 1.5 milliseconds, electric current 2A or so.And electricity protects the magnet coil of slide cam selector, since it is desired that being electrified for a long time, by conversion energization direction
Carry out work, therefore its resistance can be bigger, reach 400 ohms, the number of turn is therefore more；If in order to reduce volume, that
The enamel-covered wire of 5 or so can only be used, but this also reduces galvanomagnetic-effect, impaired performance.Therefore the line in the case of above-mentioned two kinds
Circle body product all compare it is larger, result in thimble blade can not realize less than 5 millimeters spacing arrangement.The utility model exists
Under the premise of ensureing that the power of coil is constant, standard operating voltage reduction is turned into 12V first, then increases operating current and reaches
6A, therefore can reduce corresponding coil turn, until the ohms of resistance 2, now the diameter of coil is between 6-10mm,
So that the spacing minimum between thimble blade arrives 3.2mm.
The size of center magnetic rod force is laid out in addition, the utility model changes existing magnet coil, coil is close
Set at preceding 1/3rd of bar magnet, can so greatly improve electricity, the efficiency of magnetic conversion.Meanwhile, the utility model is taken through
Control board carries out (300 to 400 microsecond), the control mode of high current (6A) in short-term to coil, realizes slide cam selector high frequency work
The ability of work, has reached the purpose for substituting potsherd slide cam selector.
In order that thimble purpose can be better achieved in thimble blade, the utility model is in the cutter head position of existing thimble blade
Put, the slanted angle and blade between a 2-5 degree are set, so when thimble blade yaw motion is to target operational position,
This has the cutter head of slanted angle just parallel with the working face on opposite, therefore can intactly push up work general work.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is thimble blade work schematic diagram of the present utility model.
Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, the electromagnetic needle selector of small spacing of the present utility model, has a housing 1 to contain, in housing 1 on part
Lower two row's close-packed arrays 12 needle selection units, often arrange 6, make above and below thimble blade 6 be staggered, and spacing to each other exists
3.2mm。
Each needle selection unit includes the thimble blade 6 with permanent magnet 5, and the magnet coil 2 with magnetic core 3, leads to
Magnet coil 2 after electricity is produced with permanent magnet 5 to be attracted or repels, and realizes the deflection up and down of thimble blade 6.As shown in Fig. 2
The cutter head position of thimble blade 6, the slanted angle that there is a 2-5 degree with blade, optimum value is 3 degree, so when thimble blade 6
When yaw motion is to target operational position, the working face of cutter head plane just with opposite is in parallel so that thimble blade 6 can be completely
Withstand on working face, stress is optimal.
Magnet coil 2 of the present utility model is set at before magnetic core 3 1/3rd, the square radome 4 of outer cover, is made
It is compacter on must arranging；A diameter of 6mm of magnet coil 2, resistance is 2 Ω, therefore the operating voltage set is 12V, electricity
Flow for 6A；The utility model is high current in short-term to the control mode of magnet coil, and control time is in 300 to 400 microseconds, so
The same impact of performance is reached with potsherd slide cam selector.
Finally, it is also noted that, listed above is only a specific embodiment of the present utility model.Obviously, this reality
Can also have many deformations with new, one of ordinary skill in the art can directly be exported from the utility model disclosure or
All deformations associated, are considered as protection domain of the present utility model.
