The frame shell 8 is in the shape of a cuboid as a whole, and it is provided with a cavity inside, and through holes are arranged on the left and right sides of the upper side for installing the crankshaft 7; It moves up and down in the groove; there are 2 pairs of card slots on the outside of the bottom interface, and its shape matches the shape of the paper outlet of the external printer, which is enough to fix the stamping machine so that it can be attached to the paper outlet of the printer.

The inside of the motor housing 4 is provided with a motor connected to the connecting rod 5 for controlling the rotation of the seal 11 .

The seal 11 is in the shape of a cylindrical roller, and the thickness of the part with the stamp pattern on its surface is 1-2mm, which can touch the paper surface during the stamping process, and the rest of the seal has a certain distance from the paper surface, so it will not touch it. Paper surface, so that the angle of the stamp can be adjusted conveniently, and the next stamping can be implemented; the width of the stamp 11 is slightly wider than the diameter of the stamp pattern by 2~4mm.

The signal output end of the CPU 14 is connected to the signal input end of each part of the motor control circuit through wires, and the signal input end of the CPU 14 is connected to the signal output end of the photosensitive processor 13 .

In actual use, the utility model is installed at the paper outlet of the printer, and the stamping steps are completed in cooperation with the printer:

1) After the printing is completed, the paper enters the automatic stamping machine along the paper outlet of the printer, and the CPU controls the stamping machine according to the user's choice. The motor drives the belt pulley, and then the belt pulley drives the stamp roller to automatically adjust the horizontal position of the stamp, and then drives the roller shaft to rise and fall through the crank slider system to determine the vertical position of the stamp. When the slider reaches the lower limit position, the stamp is printed Just touching the paper surface, on this basis, the device is in place ahead of time;

2) After the paper enters the stamping machine, the stamping roller starts to press the paper to stamp at the same speed as the paper is discharged under the drive of the built-in motors on both sides of the shaft;

3) After the stamping movement is over, the stamp will return to the initial position along the track driven by the CPU program, without affecting the subsequent paper output movement.

As shown in Figure 3, it is the schematic diagram of the circuit structure of the automatic stamping machine of the present invention, wherein the control switch is connected to the CPU; the photoelectric switch is controlled by the photosensitive processor, and is connected to the CPU and the time relay at the same time; the CPU is connected to the motor through the time relay; Connect and control the stamp. The utility model uses the normally closed and normally open contacts of the time relay to set a specific time to control the operation of the motor according to the speed of paper transmission, and uses 1 photosensitive processor, 3 time relays, an adaptive power supply, and several wires to construct the control circuit, a total of 6 drive motors for transmission, wherein the belt pulley, the crankshaft rotation center, and the end of the roller shaft are respectively provided with two drive motors for driving.

The CPU 14 adopts a 44-pin 51 single-chip microcomputer with a model of STC12C5A60S2-35I-LQFP44G; the photosensitive processor 13 adopts an arduino kit 4-wire photoresistor sensor module, and the size of a small PCB is 3.2×1.4cm; the external motor 10 adopts a model of The AC permanent magnet synchronous motor of WS-50KTYZ has a specification of 38×50mm; the time relay model is Omron H3Y-4-C, and the specification is 22×28×64mm.

As shown in Figure 4, when the relay is energized, the normally open contact of the power-off delay is closed immediately, and the normally-close contact of the power-off delay is immediately disconnected, and the motor starts to work; when a work is completed, the relay is powered off, and the normally open contact The point delay disconnection, the normally closed contact delay disconnection, the motor stops working, and waits for the next start.

At the same time, in order to ensure real-time and effective operation of the motor, a photosensitive processor 13 is added to control the start of the relay, and the photosensitive processor 13 is installed at the paper inlet. When paper enters, the photosensitive processor 13 cannot receive the signal, and the switch is closed. Power is connected to the relay and it starts working.

The CPU 14 is externally connected with four control switches A, B, C, and D, corresponding to four positions of different paper types, which can meet 95% of the stamping needs in the current market; set the opening and closing time of the relay according to the stamping position, and control the processing through the key switch to run the program.

As shown in Figure 5, in the circuit logic of the present utility model, the seal position is determined by each motor motion, and motor motion is determined by relay, and relay opening and closing is determined by CPU 14 and photosensitive processor 13; Photosensitive processor 13 in CPU 14 The interrupt processing request resides behind the key switch, that is, after the stamp affixing machine moves the stamp to the desired affixing position, then the photosensitive processor 13 detects whether the paper enters to determine whether the affixing machine starts to affix the seal.

Wherein the built-in motor in the motor shell 4 controls the scrolling of the stamp, that is, the photosensitive processor 13 detects all motor movements after the paper enters, and is in the second interrupt request; the external motor 10 controls the transverse movement of the stamp, and it will be just before the paper enters Bit, controlled by four control switches A, B, C, and D, is in the first interrupt request.

In addition to the above four control switches, there is also an end button switch, which is embedded under the first interrupt request. If the user chooses the wrong seal position, he can end the seal in advance by ending, and at the same time, the built-in motor in the control machine shell 4 selects the position again. .

When the seal request is transmitted to CPU14, CPU14 transmits the signal to 6 driving motors, the motors at both ends of the crankshaft 7 rotate 180° to lower the rollers to the lowest position, and the motors at the 3 ends of the pulley control the rollers to reach the horizontally specified position. The 1-end motor turns the part with the stamp to the bottom, and makes one side of the stamp stick to the paper surface, and rolls the stamp synchronously with the paper transmission speed.
