3352 coefficient of friction for being provided in reduction solenoid 334 has solenoid 334 so that coefficient of friction is negligible
Protective effect prevents solenoid 334 frayed and influences power effect, is based on Ohm's law, resistance and electric current are in inverse ratio, i.e., electric
Resistance is bigger, and electric current is smaller, then 332 magnetic force of iron core ring after being powered is smaller, conversely, resistance is smaller, electric current is bigger, then after being powered
332 magnetic force of iron core ring is bigger, since the iron core ring 332 after being powered is that like pole is just being oppositely arranged with permanent magnet 312, is based on magnetic
Property principle, can to permanent magnet 312 generate repulsion, the size of repulsion and the magnetic force of iron core ring 332 are proportional, and repulsion may make bar
Body 313 is overhanging under the guiding role of inner sleeve 321, and when overhanging, the body of rod 313 generates pressure to card bead 3221, so that spring 223b
It is compressed,
The setting of spring 223b has retractility based on spring, enables card bead 3221 to be detached from card hole 310, so that connecting rod
31 are able to telescopic adjustment, and the combination of guide rod 223c and connection sheet 223a are provided in the guiding of having stretched to spring 223b, limit
The effect of position effectively prevent spring 223b in flexible middle spring ring deviation, spring 223b is avoided to deform, helps to extend spring
The service life of 223b, being provided in for limited block 223d prevent guide rod 223c to be detached from movable span 222a, and groove 221a's sets
Spatial position can be provided for guide rod 223c by, which setting, is inside contracted, furthermore such that next card bead 3221 then passes through upper one card
Position hole 310 carries out detent to connecting rod 31 and fixes, and inside contracting for connecting rod -31 can be by the power-off of iron core ring -332, directly to pressure roller -
2 forces, so that spring -223b, card bead -3221 are forced in indirectly, so that connecting rod -31 is directly inside contracted.
To sum up, the technological progress that the present invention obtains compared with the prior art is: adjustable type pressure roller of the invention passes through resistance tune
The combination setting of the components such as the fixed group of device, detent, permanent magnet, metal nuts pair, metal screw rod, pulley blocks is saved, it is exhausted by rotating
Edge turntable can carry out job area adjusting to pressure roller based on Ohm's law and magnetic principles, time saving and energy saving, adjust difficulty system
Number is low, can quickly be adjusted, can shorten regulating time, the very fast feeling of pain for reducing puerpera.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
