When the invention is used, firstly, a power supply of the device is switched on, after the power supply is switched on, the electromagnetic ring 7 at the outer side of the end part of the appointed output shaft 3 is electrified according to the printing requirement of a printing production piece, the electromagnetic ring 7 can generate extremely strong magnetism to attract the magnetic filling block 15 after being electrified, so that the magnetic filling block 15 compresses and contracts the limiting spring 17 to enter the output shaft 3, at the same time, the light spring 16 can lose the constraint of the force transmitted by the magnetic filling block 15 through the ejection connecting block 14, at the same time, the light spring 16 can eject the ejection connecting block 14, so that the end part of the ejection connecting block 14 is clamped in the clamping groove generated after the magnetic filling block 15 contracts, at the same time, the connecting shaft 11 can be mutually connected with the output shaft 3, then the motor 4 is started, so that the motor 4 drives the input gear 10 to rotate, so that the input gear 10 directly drives the output gear 8 meshed with the, the connecting shaft 11 fixed with the output gear 8 is enabled to synchronously rotate, when the connecting shaft 11 rotates, the connecting shaft 11 connected with the output shaft 3 can drive the output shaft 3 to synchronously rotate through the ejection connecting block 14, and other output shafts 3 are not connected with the connecting shaft 11 through the ejection connecting block 14, so only the connected output shaft 3 rotates, the rotating output shaft 3 can outwards convey the motion, so that the printing machine works, because the transmission ratios between the input gear 10 and a plurality of output gears 8 outside the input gear are different, when the input gear 10 drives different output gears 8 to rotate, the printing machine can obtain different running speeds, speed adjustment can be performed according to the printing requirements of products, so that the products can be better printed, the generation of quality defects is reduced, the qualification rate of the products is effectively improved, the structure is simple, the weight of the printing machine is simple, the weight of the printing, The operation is convenient.
Because the connecting shaft 11 is in a rotating state when in use, the push-out connecting block 14 connected with the light spring 16 is inevitably under the action of centrifugal force, although the elastic force setting between the spring and the light spring is limited by the action of the invention, so that a better effect can be realized, when in actual high-precision and fast printing, the push-out connecting block is usually required to be capable of fast reaction, and when the speed is higher, the movement of the push-out connecting block 14 is difficult to avoid, if the elastic force of the limiting spring is set to be larger, the magnetic filling block 15 is easy to recover under the high-speed rotation, even on the connecting shaft 11 when the printing is not required, the magnetic filling block is also rotated, and the speed of the magnetic filling block may be continuously changed to meet different requirements.
To this end, further improvements are made to solve the above problems, the scheme and the control method are as follows: as shown in fig. 5-7, the electromagnetic ring 7 includes a magnetic conducting rod 18 extending to one side of the connecting shaft 11, although only one magnetic conducting rod 18 is shown in the drawings, a vertical sleeve 23 is disposed in a position of the connecting shaft 11 corresponding to the magnetic conducting rod 18, it should be understood that the magnetic conducting rod 18 may be disposed on two sides corresponding to the vertical sleeve 23, a plurality of first sleeves 19 are disposed inside the connecting shaft 11 on one side of the vertical sleeve 23 away from the motor 4, a first magnet 22, a first spring 20 and a first limit block 21 are sequentially disposed in each first sleeve 19, a position of the output shaft 3 corresponding to the first limit block 21 has a matching limit hole, and the output shaft can be better driven by matching the limit hole with the first limit hole 21, and after the ejection connecting block 14 is ejected to the position of the magnetic filling block 15, the reset of the limiting spring 17 may occur due to the speed change during the rotation, so that the power loss between the connecting shaft 11 and the output shaft 3 may occur during the connection process, the loss may be recovered by the action of the electromagnetic ring 7, but even the short loss means the speed change of the output shaft 3, which causes the printing problem or the printing precision problem, the second magnet 25 is disposed on both sides of the vertical spring 24, the third magnet 26 is disposed on one side of the second magnet 25 close to the vertical sleeve 23, the fourth magnet 27 is disposed on one side of the second magnet 25 far from the vertical sleeve 23, the third magnet 26 and the second magnet 25 are connected through a fixed column, the fourth magnet 27 and the second magnet 25 are connected through a fixed column, and the sliding block is disposed on the outer side of the ejecting connection block 14, the sliding block embeds there is second sleeve 28, fifth magnet 30, second spring 29 and second stopper 31 have connected gradually in the second sleeve 28, ejecting connecting block 14 outside corresponds the spacing hole of second stopper 31, second magnet 25 can receive the magnetic force effect on the magnetic pole 18, second magnet 25 can vertical spring 24 is in balanced primary importance, and second magnet 25 receives be located the second position behind the magnetic force effect of magnetic pole 18, during the primary importance, third magnet 26 with fifth magnet 30 repels and makes second stopper 31 can be right ejecting connecting block 14 is spacing, and during the second position, fourth magnet 27 can be right first magnet 22 repels, makes first stopper 21 can be right output shaft 3 carries on spacingly.
When the electromagnetic ring is used, if the output shaft 3 does not need to be driven, the third magnet 26 repels the fourth magnet 30, so that the second limiting block 31 can extend out of the sliding block, and the limiting hole on the ejection connecting block 14 is limited, so that the ejection connecting block 14 is always fixed in the connecting shaft 11, and the state change caused by disturbance and speed change on the connecting shaft 11 is avoided, when the output shaft 3 needs to be driven, the electromagnetic ring 7 is opened, so that the electromagnetic ring 7 adsorbs the magnetic filling block 15, the magnetic filling block 15 compresses the limiting spring 17, so that the ejection connecting block 14 can enter the output shaft 3 for driving, meanwhile, when the electromagnetic ring 7 generates magnetic force, magnetism appears on the magnetic conducting rod 18, the magnetism repels the second magnet 25, and through the arrangement of the magnetic force, the second magnet 25 can compress the vertical spring 24, so that the second magnet 25 can stay at the position corresponding to the first magnet 22, at this time, due to the repulsive action of the fourth magnet 27 to the first magnet 22, the first stopper extends out of the connecting shaft and enters the corresponding stopper hole on the output shaft 3, so that the driving is more stable, the output shaft 3 is not separated from the connecting shaft 11 due to the change of speed and interference, when the release is needed, the electromagnetic ring 7 is powered off, so that the magnetic filling block 15 is reset under the action of the limiting spring 17, so that the ejection connecting block 14 enters the inside of the connecting shaft 11 again, meanwhile, the electromagnetic ring 7 is powered off, so that the magnetic conducting rod 18 no longer has magnetism, at this time, due to the reset action of the vertical spring 24, the second magnet 25 and the third and fourth magnets driven by the second magnet 25 are reset to the initial position again, at this position, the first magnet 22 will not be repelled by the fourth magnet 27 any more, so that the first stopper 21 will receive the restoring force of the first spring 20, thereby releasing the limitation of the output shaft 3, and at the same time, since the third magnet 26 again corresponds to the fifth magnet 30, the third magnet 26 will repel the fifth magnet 30 again, thereby the second stopper 31 again extends out of the sliding block to limit the ejection connecting block 14.
Therefore, the invention can realize the stable control of the output shaft by matching the electromagnetic ring 7 which is actively controlled through the matching action of the first magnet to the second magnet, so that the invention can not be influenced by the speed of the connecting shaft 11 and the interference of shaking and the like, can stably ensure the driving output of the output shaft, and can quickly and stably ensure the printing quality and speed, so that the two can be realized simultaneously. According to actual needs, the output shafts 3 can drive one or two or more of the output shafts 3 under the control of the controller, so that the driving at different speeds can be met, meanwhile, the output shafts can be output by one motor 4, even through the arrangement of gear ratios, the whole device can drive all rotating parts of the whole printing by only one motor 4, and the whole device is extremely simple and convenient.
