Based on this, the invention provides a cutter control circuit and system, which can effectively reduce the complexity of control logic and better monitor the completion condition of cutting action, thereby effectively improving the safety when the cutting action is executed.
To facilitate understanding of the present embodiment, a detailed description will be given of a cutter control circuit disclosed in an embodiment of the present invention.
The invention provides a cutter control circuit which comprises a cutter driving circuit, a switch circuit and a switch feedback circuit which are sequentially and electrically connected. The cutter driving circuit is also electrically connected with a processor (CPU), and is used for receiving a cutter control signal of the processor and outputting a motor control signal to the switching circuit according to the cutter control signal; the switch circuit is also electrically connected with the motor and is used for being in a closed state when receiving the motor control signal and controlling the motor to drive the cutter to execute a cutting action according to the motor control signal; the switch feedback circuit is also electrically connected with the processor and is used for monitoring the opening and closing state of the switch circuit and feeding the opening and closing state back to the processor so that the processor can determine whether the cutting action is finished or not based on the opening and closing state.
For convenience of understanding, fig. 1 illustrates a schematic structure of a cutter control circuit, which includes a cutter driving circuit 110, a switch circuit 120 and a switch feedback circuit 130, as shown in fig. 1.
In one embodiment, the cutter driving circuit 110 is electrically connected to the processor, receives a cutter control signal sent by the processor, and outputs a corresponding motor control signal to the switch circuit according to the cutter control signal, where the cutter control signal is used to instruct the cutter driving circuit to send a motor control signal to the switch circuit, and the motor control signal is used to instruct the switch circuit to control the motor to rotate, so as to drive the cutter to perform a corresponding cutting action by the motor, and the cutting action may include a half-cut action or a full-cut action. Alternatively, the cutter control signal may take the form of a set of levels, with different sets of levels representing different cutter control signals. For example, the motor will be in a braking state when the cutter control signal comprises two high levels; when the cutter control signal comprises a low level and a high level, the cutter driving circuit sends a motor control signal rotating in the forward direction to the switching circuit; when the cutter control signal comprises a high level-a low level, the cutter drive circuit will send a motor control signal to the switch circuit for reverse rotation.
In one embodiment, the switch circuit 120 is electrically connected to a motor, which is a dc motor, and when receiving a motor control signal issued by the cutter driving circuit 110, the switch circuit is closed, and the motor is controlled to rotate according to the motor control signal, so that the motor drives the cutter to perform a corresponding cutting action. For example, when a motor control signal for forward rotation is received, the motor is controlled to rotate forward, and at the moment, the cutter performs half-cutting action; when a motor control signal of the reverse rotation is received, the motor is controlled to rotate reversely, and at the moment, the cutter performs the full cutting action.
In one embodiment, a switch feedback circuit 130 is also electrically connected to the processor, the switch feedback circuit being configured to monitor the on/off state of the switch circuit and feed back the on/off state to the processor, and in one embodiment, the on/off state of the switch circuit can be determined by monitoring a voltage level at a designated pin of the switch circuit. For example, when the level at the designated pin is high, the switch circuit is determined to be in an off state, and the processor determines that the cutter does not execute the cutting action or the cutting action is finished; when the level at the designated pin is low, it is determined that the switch circuit is in a closed state and the processor will determine that the cutter is performing a cutting action.
The cutter control circuit provided by the embodiment of the invention can effectively simplify the control logic of the cutter control circuit, and the on-off state of the switch circuit is monitored by the switch feedback circuit, so that the processor can know the completion condition of the cutting action based on the on-off state, and the safety of executing the cutting action can be effectively improved.
In one embodiment, the cutter drive circuit comprises a first input electrically connected to the processor and a first output electrically connected to the switching circuit. In one embodiment, the cutter control signal includes a half-cut signal and a full-cut signal, and the motor control signal includes a forward rotation signal (i.e., the forward rotation motor control signal) and a reverse rotation signal (i.e., the reverse rotation motor control signal). When the first input end receives the half-cut signal, the first output end outputs a forward rotation signal to the switch circuit; when the first input end receives the full-cut signal, the first output end outputs a reverse rotation signal to the switch circuit.
Illustratively, when receiving a half-cut signal sent by the processor through the first input end, the cutter driving circuit sends a forward rotation signal to the switch circuit through the second output end, and when receiving the forward rotation signal, the second switch circuit is closed and controls the motor to rotate forward to drive the cutter to perform a half-cut action; the cutter driving circuit sends a reverse rotation signal to the switch circuit through the second output end when receiving a full-cutting signal sent by the processor through the first input end, and the second switch circuit is closed when receiving the reverse rotation signal and controls the motor to rotate reversely so as to drive the cutter to execute full-cutting action. When the cutter executes half-cutting action or full-cutting action, the switch feedback circuit monitors that the switch circuit is in a closed state and feeds the closed state back to the processor, so that the processor knows that the cutter executes corresponding cutting action.
In order to facilitate understanding of the cutter control circuit provided in the foregoing embodiment, the embodiment of the present invention further provides a specific structure of a cutter control circuit, and referring to a schematic structural diagram of another cutter control circuit shown in fig. 2, in this embodiment, the cutter driving circuit 110 includes a cutter driving chip, a first input end includes a first driving pin 111 and a second driving pin 112 of the cutter driving chip, a first output end includes a third driving pin 113 and a fourth driving pin 114 of the cutter driving chip, and in addition, the cutter driving circuit further includes a fifth driving pin 115, a sixth driving pin 116, and a seventh driving pin 117.

The first level IN1 and the second level IN2 are both output from the processor, and the cutting knife is controlled to execute the paper cutting action by the cooperation of the first level IN1 and the second level IN 2.
In order to facilitate understanding of the above-mentioned cutter driving chip, the embodiment of the present invention provides a functional description table of the cutter driving chip, which is referred to as table 1 below. The first driving pin 111 corresponds to a symbol IN1 and is an input control pin of a transistor-transistor logic (TTL) level; the second driving pin 112 corresponds to the symbol IN2 and is also an input control pin of TTL level; the third driving pin 113 corresponds to the symbol OUTA, is an output terminal, and may output GND (ground) or VCC (Volt Current connector, power supply voltage) according to different input TTL levels, where GND may be a low level and VCC may be a high level; the fourth driving pin 114 corresponds to the symbol/OUTA and is also an output terminal, and outputs GND or VCC according to different input TTL levels, where when the driving motor rotates, the levels of the third driving pin 113 and the fourth driving pin 114 are opposite; the fifth driving pin 115 corresponds to a symbol GND and is a ground terminal, and the sixth driving pin 116 corresponds to a symbol VCC and is a voltage input terminal for providing driving voltage for the motor; the seventh driving pin 117 corresponds to a symbol NC, which is undefined.
TABLE 1
IN practical applications, the half-cut signal includes the first level IN1 being a low level and the second level IN2 being a high level, the full-cut signal includes the first level IN1 being a high level and the second level IN2 being a low level, the forward-rotation signal includes the third level OUTA being a low level and the fourth level/OUTA being a high level, and the reverse-rotation signal includes the third level OUTA being a high level and the fourth level/OUTA being a low level.
For example, referring to the control schematic diagram of a cutter driving chip shown IN fig. 3, when the first level IN1 sent by the processor to the first driving pin 111 and the second level IN2 sent by the processor to the second driving pin 112 of the cutter driving circuit are both high levels, the third level OUTA output by the third driving pin 113 and the fourth level/OUTA output by the fourth driving pin 114 of the cutter driving circuit are both low levels, and at this time, the dc motor is IN a braking state; when the first level IN1 sent by the processor to the first drive pin 111 is low level and the second level IN2 sent to the second drive pin 112 is high level, the third level OUTA output by the third drive pin 113 is low level, the fourth level/OUTA output by the fourth drive pin 114 is high level, at this time, the direct current motor rotates forward, and the cutter performs half-cut operation; when the first level IN1 sent to the first driving pin 111 by the processor is at a high level and the second level IN2 sent to the second driving pin 112 by the processor is at a low level, the third level OUTA output by the third driving pin 113 is at a high level, and the fourth level/OUTA output by the fourth driving pin 114 is at a low level, at this time, the dc motor rotates IN a reverse direction, and the cutter performs a full-cutting action.
With continued reference to fig. 2, fig. 2 also illustrates that the switch circuit 120 includes a first switch pin 121, a second switch pin 122, a third switch pin 123, and a fourth switch pin 124. The first switch pin 121 is electrically connected to the third driving pin 113, the second switch pin 122 is electrically connected to the fourth driving pin 114, the third switch pin 123 is grounded, and the fourth switch pin 124 is electrically connected to the switch feedback circuit 130. In practical application, when a forward rotation signal is received through the first switch pin 121 and the second switch pin 122, the motor is controlled to rotate forward to drive the cutter to perform a half-cutting action; when receiving the reverse rotation signal through the first switch pin 121 and the second switch pin 122, the motor is controlled to rotate in the reverse direction to drive the cutter to perform the full cutting action. Optionally, the switch circuit may adopt a socket, wherein a first switch pin 121 and a second switch pin 122 of the socket are connected to the dc motor, a third switch pin 123 is grounded, and a fourth switch pin 124 is connected to the micro switch.
IN this embodiment, when the first level IN1 and the second level IN2 are both high levels, the third level OUTA and the fourth level/OUTA are both low levels, the third switch pin 123 and the fourth switch pin 124 are controlled to be disconnected, and the switch feedback circuit 130 monitors that the fifth level of the fourth switch pin 124 is high level. When a forward rotation signal or a reverse rotation signal is received through the first switch pin 121 and the second switch pin 122, the third switch pin 123 and the fourth switch pin 124 are controlled to be closed, and the switch feedback circuit 130 monitors that the fifth level of the fourth switch pin 124 is a low level. Illustratively, before the cutting knife starts to perform a cutting action, or when a cutting action is completed, the third switch pin 123 and the fourth switch pin 124 are disconnected, and the fifth level at the fourth switch pin 124 is a low level; when the cutter starts to perform a cutting action, the gap between the third switch pin 123 and the fourth switch pin 124 is closed, and the fifth level at the fourth switch pin 124 is a high level.

When the fifth level is detected to be a high level through the second input terminal 131, the second output terminal 132 is in an off state to the processor feedback switch circuit 120; when the fifth level is detected as a low level by the second input terminal 131, the second output terminal 132 is in a closed state to the processor feedback switch circuit 120. Optionally, the switch feedback circuit 130 may send a cutter status feedback signal CUTT to the processor to inform the processor of the current status of the cutter (such as cutting action being performed, or no cutting action being performed).
With continued reference to fig. 2, fig. 2 further illustrates that the switch feedback circuit 130 further includes a first resistor R1, a second resistor R2, a first diode D1, a second diode D2, a capacitor C, and a transistor Q. Wherein, the cathode of the first diode D1 is a second input end, the anode of the first diode D1 is connected with the first power supply (for example, 3.3V) through the first resistor R1, the anode of the first diode D1 is grounded through the capacitor C, and the anode of the first diode D1 is connected with the anode of the second diode D2; the cathode of the second diode D2 is connected with the base electrode of the transistor Q; the emitter and collector of the transistor Q are grounded, the collector of the transistor Q is a second output terminal, and the collector of the transistor Q is further connected with the first power supply through a second resistor R2. The resistance of the first resistor R1 is 1K, and the resistance of the second resistor R2 is 4.7K. In the present embodiment, the voltage of the fourth switch pin 124 of the switch circuit is high both before the beginning of the cutting action and after the completion of one cutting action, and is low during the cutting action. The processor judges when the cutter finishes the paper cutting action by judging the voltage of the fourth switch pin 124, and stops sending the cutter driving signal to the cutter driving circuit.
