The air inlet 29 and the communicating pipe 27 are both provided with one-way valves, the one-way valve in the air inlet 29 only allows air to enter the groove 4 from the outside, and the one-way valve in the communicating pipe 27 only allows air to enter the mounting cavity 24 from the groove 4.
The number of teeth of the first rack 39 is identical to that of the second rack 40, the number of teeth of the main gear 23 is four times that of the first rack 39, and the main gear 23 can rotate 90 degrees when passing through the first rack 39 and the second rack 40 through the arrangement of the number of teeth, so that the top block 20 rotates 90 degrees each time, and the state of the clamping plate 9 is changed.
In the invention, in the running process of the machine, a to-be-printed object is placed in a placing groove 51, the to-be-printed object is clamped and fixed through two clamping plates 9, at the moment, a servo motor 42 drives a driving gear 43 to rotate, a gear ring 44 is driven to rotate through the rotation of the driving gear 43, the gear ring 44 rotates to drive a rotary table 3 to rotate, each printed object passes through different pad printing mechanisms 41, and the pad printing mechanisms 41 pad print different color patterns on the printed object.
In the process of pad printing, the printing rubber head of the pad printing mechanism 41 applies pressure to a to-be-printed object to pad printing, in the process of applying the pressure, the lifting block 5 is enabled to slide downwards by the pressure, so that when the pump plate 6 is driven to slide downwards by the connecting rod 7, the pump plate 6 slides downwards, if the pressure is enough, the pressure can enable the pressure relief valve 28 to be opened at the moment, air in the groove 4 is pumped into the mounting cavity 24, after pad printing is completed, the pressure is relieved, at the moment, the pump plate 6 and the lifting block 5 slide upwards under the elasticity of the third spring 21, and outside air is pumped into the groove 4 through the air inlet 29 to wait for pumping.
If the pressure is insufficient, the pad printing pattern text may be unclear, the pressure cannot be made to open the pressure release valve 28, at this time, no air is pumped into the installation cavity 24, but the air pumped into the installation cavity 24, because the electromagnetic valve 53 is in a closed state, the pumped air enters the third sliding sleeve 19 through the through hole 26, so that the third sliding column 22 slides downward for a certain distance, i.e. when six pad printing is performed, if the pad printing pressure is sufficient for six times, the third sliding column 22 slides downward for six times, and if one or more pad printing pressures are insufficient, the number of times that the third sliding column 22 slides downward is smaller than six times.
After the pad printing is completed for six times, if the pad printing pressure is sufficient, at this time, the third sliding column 22 drives the main gear 23 to descend for six times, at this time, the position of the main gear 23 can be meshed with the first rack 39, at this time, along with the rotation of the turntable 3, when the printed matter after the pad printing is completed for six times passes through the first rack 39, the main gear 23 rotates through the meshing with the first rack 39, the rotation of the main gear 23 drives the third sliding column 22 to rotate, so that the third sliding sleeve 19 rotates, the top block 20 is driven to rotate by 90 degrees, the rotation of the top column 20 can enable the two clamping plates 9 to move oppositely, the clamping of the printed matter is released, at the same time, the third conductive block 36 and the fourth conductive block 37 are released, so that the electromagnetic valve 53 is electrified to be opened, under the elasticity of the fourth spring 25, the third sliding column 22 drives the main gear 23 to reset slowly, at this time, because the third sliding sleeve 19 rotates, the following block 32 is driven to move, so that the first conductive block 34 and the second conductive block 35 are separated, and the alarm lamp 38 is not lighted.
The clamping plate 9 releases the clamping and drives the first sliding column 16 to slide, hydraulic oil in the first sliding sleeve 15 is pumped into the second sliding sleeve 17 through the fixed pipe 52, so that the second sliding column 18 slides out to drive the driving ring 14 to move, the driving ring 14 drives the jacking column 12 to slide through damping force, the jacking column 12 slides outwards to push out the printing matters released from the clamping out of the placing groove 51 and drop down, then the jacking column 12 resets under the elasticity of the second spring 13 to collect the dropped printing matters, then the turntable 3 continues to rotate, the main gear 23 is meshed with the second rack 40, the jacking block 20 rotates 90 degrees again to be separated from the clamping plate 9, the printing matters are placed into the placing groove 51, and then the clamping plate 9 clamps the printing matters to be printed under the elasticity of the first spring 10 again to transfer printing along with the rotation of the turntable 3.
If the pressure is insufficient once or more times after the six pad printing is completed, at this time, the third sliding column 22 drives the main gear 23 to descend for six times, at this time, when the printed matter passes through the first rack 39, the main gear 23 cannot be meshed with the first gear 39, that is, the third sliding sleeve 19 does not rotate, so that the clamping plate 9 still clamps the printed matter and ensures that the printed matter is in the placing groove 51, meanwhile, the third conductive block 36 is in contact with the fourth conductive block 37, at this time, the third sliding sleeve 19 does not rotate, the follower block 32 does not move correspondingly, so that at this time, the first conductive block 34 and the second conductive block 35 keep in contact, at this time, the alarm lamp 38 is electrified to be lightened, after a worker observes that the alarm lamp 38 is lightened, immediately stopped, the pad printing is stopped, the printed matter at the alarm lamp 38 is taken out, where the pad printing pattern is observed, an unclear point exists, and the pad printing mechanism 41 corresponding to the unclear point is found, and the pad printing is continuously performed after the adjustment is completed.
The above description is only of the preferred embodiments of the present invention; the scope of the invention is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present invention, and the technical solution and the improvement thereof are all covered by the protection scope of the present invention.
