[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In one embodiment, a control circuit for a multi-dispenser recyclable material recycling device is provided, such as... Figure 1-8 As shown, the control circuit of the multi-port recyclable waste recycling equipment includes a power supply module and a main control module. The power supply module provides a voltage source for other electronic components in the control circuit. The power supply module provides a voltage source by converting 12V DC to 3.3V DC. The 3.3V DC is used by low-voltage electronic components. The main control module is the signal processing and logic control center of the control circuit and can be composed of a microcontroller and its peripheral circuits.

[0027] The control circuit of this multi-dispensing recyclable material recycling equipment also includes a motor drive module and a weighing signal processing module. Since the equipment requires weighing of recyclable materials and the dispensing baffles need to be opened and closed by a motor, the motor drive module and weighing signal processing module are included. The motor drive module comprises three motor drive units, suitable for multi-dispensing recyclable material recycling equipment with three dispensing ports. Each motor drive unit drives the motor at one dispensing port. Each motor drive unit includes a motor driver and a current sensor. The motor driver is used to drive the recyclable material... The motor at the inlet of the recyclable material recycling equipment has a current sensor used to measure its operating current. During use, the motor driver and the current sensor are connected in series in the motor circuit. The motor driver and the current sensor are electrically connected to the main control module. The main control module controls the operating state of the motor driver, thereby controlling the forward and reverse rotation and braking of the motor. The current sensor detects the operating current of the motor. If the current suddenly increases, it indicates that the motor is obstructed, meaning that the baffle on the inlet is blocked. At this time, the main control module controls the motor to reverse and open the baffle on the inlet to prevent objects from being caught and causing danger.

[0028] The weighing signal processing module includes a three-channel analog-to-digital converter. The analog-to-digital converter is used to convert the weighing signals output by the weighing sensors of the three weighing platforms on the recyclable material recycling equipment from analog to digital. The analog-to-digital converter is electrically connected to the main control module and transmits the converted digital signal to the main control module.

[0029] like Figure 2 As shown, the power module of the control circuit of the multi-port recyclable material recycling equipment includes an XL1509-ADJE1 step-down converter and two AMS1117-3.3 voltage regulators. The XL1509-ADJE1 step-down converter has an external circuit consisting of diodes D1 and D2, capacitors C1, C2, C3, C4, and C5, inductor L1, and resistors R1 and R2. The two AMS1117-3.3 voltage regulators are set to ensure stable and reliable power supply. The first AMS1117-3.3 voltage regulator U2 has an external circuit consisting of capacitors C6 and C7, and the second AMS1117-3.3 voltage regulator U3 has an external circuit consisting of capacitors C8 and C9.

[0030] like Figure 3 As shown, the main control module of the control circuit of the multi-dispenser recyclable material recycling equipment includes a CH32V103R8T6 microcontroller. The microcontroller is equipped with an 8MHz clock and a peripheral circuit consisting of several capacitors (such as capacitor C12) and resistors (such as resistor R4 in the figure). The microcontroller controls the working indicator LED1 through transistor Q1 to indicate that the control circuit of the multi-dispenser recyclable material recycling equipment is in normal working condition.

[0031] like Figure 4 As shown, the control circuit of this multi-port recyclable material recycling equipment has three motor drivers, namely chip U6, chip U8, and chip U10, all of which are RZ7899 drivers. The corresponding three current sensors are chip U7, chip U9, and chip U11, all of which are CC6903SO-10A current sensors.

[0032] like Figure 7 As shown, the three analog-to-digital converters in the control circuit of the multi-port recyclable material recycling equipment are chip U19, chip U20 and chip U21, all of which are HX710A converters. Each of the three analog-to-digital converters has an external circuit consisting of resistors and capacitors. For example, chip U19 is equipped with an external circuit consisting of resistor R23, resistor R24, capacitor C32 and capacitor C10.

[0033] Furthermore, in another embodiment, such as Figure 5As shown, the control circuit of the multi-dispenser recyclable waste recycling equipment also includes a first switch module. The first switch module includes three relays for controlling the exhaust fan, heater, and main lighting on the recyclable waste recycling equipment. The three relays are switches K1, K2, and RLY2. These three relays include two SRD-12VDC-SL-A normally open power relays and one SLA-12VDC-SL-A electromagnetic relay. The control coils of each relay are electrically connected to the main control module through Darlington transistors. The Darlington transistors are ULN2001D Darlington transistors, so that the main control module can control the operation of the exhaust fan, heater, and main lighting. The exhaust fan and heater work together to dehumidify the inner chamber of the multi-dispenser recyclable waste recycling equipment, and the main lighting illuminates the inner chamber. The first switch module also includes three field-effect transistors for controlling the supplementary lighting. The supplementary lighting is a light strip in the inner compartment of the multi-port recyclable material recycling equipment. The three field-effect transistors are transistors Q3, Q4 and Q5, and the field-effect transistors are AO3400A field-effect transistors. The control terminals of each field-effect transistor are electrically connected to the main control module, and the main control module controls the three supplementary lights to turn on or off.

[0034] Furthermore, in another embodiment, such as Figure 6 As shown, the control circuit of the multi-slot recyclable waste recycling equipment also includes a second switch module. This second switch module comprises seven optocouplers, namely chips U12-U18, all of which are EL817S1(C)(TU)-F optocouplers. The pins on the light source side of these optocouplers are electrically connected to the corresponding sensors, and the pins on the receiver side are electrically connected to the main control module. The sensors include three ultrasonic sensors for detecting whether the recycling equipment is overflowing, three anti-pinch sensors for the slots, and one infrared sensor penetrating the inner compartment for counting. The anti-pinch sensors are electromagnetic induction sensors; when an object obstructs the slot, the anti-pinch sensor generates a signal that is transmitted to the main control module, which then controls the motor on the corresponding slot to stop or reverse. Taking the power connection method of optocoupler U12 as an example, the positive terminal of the light source side of optocoupler U12 is electrically connected to a 12V voltage source through resistor R13, and the negative terminal is connected to an anti-pinch sensor. The collector of the light receiver side of optocoupler U12 is connected to the FJ_01 pin of the main control module, and the emitter is grounded. When the anti-pinch sensor is activated, the light source side of optocoupler U12 emits light, and the light receiver side generates a signal, which is then sensed by the main control module.

[0035] Furthermore, in another embodiment, such as Figure 8As shown, the control circuit of the multi-port recyclable waste recycling equipment also includes a temperature sensing module. The temperature sensing module is electrically connected to the main control module. The temperature sensing module is used to sense the temperature of the recyclable waste recycling equipment, enabling it to have a fire-proof sensing function. The temperature sensing module here includes a GX21M15 temperature digital converter and is equipped with an external circuit consisting of resistors R29-R32.

[0036] Furthermore, in another embodiment, such as Figure 1-8 As shown, the control circuit of the multi-dispenser recyclable material recycling equipment also includes multiple pluggable terminal blocks, which include... Figure 4 CN1, a pluggable terminal block with 6 terminals. Figure 5 The six-terminal pluggable terminal block CN2 and CN3 are examples of six-terminal pluggable terminal blocks. Figure 6 CN4 is a pluggable terminal block with 12 terminals, and CN5 is a pluggable terminal block with 9 terminals. Figure 7 The CN6 is a pluggable terminal block with 12 terminals, which allows external sensors, motors, and other components to be connected to corresponding electronic devices.
