Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific examples and accompanying drawings. It should be noted that the directional terms mentioned in the examples, such as "up", "down", "middle", "left", "right", "front", "rear", etc., only refer to the directions of the drawings.

The above-mentioned feeding mechanism is located just above the left side of the base 5 . The feeding mechanism includes a feeding hopper 3 , a hopper support 1 , a hopper 2 , two feeding hopper supports 4 and two rollers 7 . The feeding hopper 3 is horizontally arranged just above the left side of the base 5 and extends in the left-right direction, and its cross-section is U-shaped. The conveying hopper of the pellets adopts a U-shaped design. Under the action of the gravity of the pellets and the oscillation mechanism, the pellets can be distributed in a single row. The hopper bracket 1 is erected above the left side of the feeding hopper 3 , and the hopper 2 is installed on the hopper bracket 1 . The bottom of the hopper 2 is designed with a beveled surface, and the connection between the hopper support 1 and the feeding hopper 3 is designed with a beveled surface, and the angle of the inclined surface is the same as the cut angle at the bottom of the hopper 2. By adjusting the slope angle of the chamfered surface of the bottom end of the hopper 2 and the connection between the hopper support 1 and the feeding hopper 3, the feeding speed of the pellets is controlled, so that the self-weight of the hopper 2 can be controlled to feed the material. When the inclined plane of the bottom end of the hopper 2 is opposite to the inclined direction of the inclined plane where the hopper support 1 and the feeding hopper 3 are connected, the feeding speed is the fastest; as the hopper 2 rotates on the hopper support 1, the feeding speed gradually becomes slower; when When the inclined plane of the bottom end of the hopper 2 is the same as the inclination direction of the inclined plane where the hopper bracket 1 and the feeding hopper 3 are connected, the feeding port is sealed and the feeding is stopped. The upper ends of the two feeding hopper brackets 4 are respectively fixed under the left and right sides of the feeding hopper 3 . The lower end of each hopper bracket 1 is provided with a roller 7 , and the roller 7 is in contact with the roller guide rail 6 provided on the base 5 . The roller 7 adopts a concave design, which matches the convex design of the roller guide rail 6 on the base 5, which ensures the movement direction and movement stability of the feeding hopper 3, as shown in Figure 2.

Under the control of the control circuit, after the bilateral asymmetric oscillating mechanism is energized, the strong magnetic electromagnet 9 and the weak magnetic electromagnet 13 are alternately energized. Under the action of the attractive force, the feeding hopper 3 performs oscillating motions with different accelerations along the roller guide rail 6 under the support of the roller 7 and the support of the roller 7 . Under the action of inertia, the pellets move in the direction of the conveyor belt 17 in the oscillation. The design of the structure of the spring 10 avoids the collision between the movable support plate 11 and the fixed bracket, and the collision between the iron piece and the strong magnetic electromagnet 9 and the weak magnetic electromagnet 13 during the movement of the feeding hopper 3, so that the oscillation process can be carried out smoothly. The asymmetric oscillation mechanism uses the principle of bilateral asymmetric electromagnetic oscillation, so that the feeding hopper 3 generates different accelerations before and after under the action of asymmetric electromagnetic force. The forward acceleration is greater than the backward acceleration, and the pellets move backward under the action of inertia. , so that the pellets are distributed in a single row under the action of its own weight and the vibration of the feeding hopper 3 .

The above-mentioned transfer mechanism is located just above the middle of the base 5 . The conveying mechanism includes a conveying belt 17 , two transmission wheels 15 , two transmission brackets 18 and a transmission motor 16 .

The level of the conveyor belt 17 is lower than that of the feeding hopper 3 , and the left end of the conveyor belt 17 is located just below the right end of the feeding hopper 3 , so that the pellets sent by the feeding hopper 3 can fall on the conveyor belt 17 . The lower ends of the two transmission brackets 18 are fixed on the base 5 , a transmission wheel 15 is arranged above each transmission bracket 18 , and the conveyor belt 17 is nested on the two transmission wheels 15 . The output end of the transmission motor 16 is connected with the transmission wheel 15, and the transmission wheel 15 is controlled to rotate clockwise to drive the upper surface of the conveyor belt 17 to move from left to right, and the pellets sent by the feeding mechanism are sent to the collecting mechanism.

The above-mentioned collecting mechanism is located just above the right side of the base 5 . As shown in Figure 3, the collecting mechanism includes a collecting bin 27, an infrared emitting tube 19, an infrared receiving tube 20, a partition plate 23, an upper electromagnet 24 at the warehouse mouth, an adsorption iron sheet 25 on the partition plate, and a lower electromagnet 26 at the warehouse mouth.

The upper side of the discharge port of the collecting bin 27 is provided with an upper electromagnet 24 at the entrance, and the lower side of the collecting bin 27 is provided with a lower electromagnet 26 at the entrance. The discharge port of the collection bin 27 is opposite to the right end of the conveyor belt 17 .

The infrared emitting tube 19 and the infrared receiving tube 20 are arranged in the inner cavity of the collecting bin 27 and relatively fixed in the middle of the front and rear side walls of the collecting bin 27 . The display screen 21 and the keyboard 22 are arranged on the outer side wall of the collecting bin 27 . The infrared emitting tube 19 and the infrared receiving tube 20 constitute an infrared counter, which is installed at an angle of 45° with the conveyor belt 17, wherein the infrared emitting tube and the infrared receiving tube are respectively installed on the two sides of the collection bin 27 adjacent to the conveyor belt 17. , and the position is relative. Driven by the conveyor belt 17, the pellets move to the right end of the conveyor belt 17. When the pellets reach the position at an angle of 45° with the plane of the conveyor belt 17, the pellets will fall into the collection bin 27 under the action of their own weight. At this time, the signal sent by the infrared emitting tube 19 is blocked by the pellets, the signal received by the infrared receiving tube is blocked, and the counter counts the falling pellets. The data is processed by the control circuit, and the state of the bilateral asymmetric oscillation mechanism, the transmission motor 16 in the conveyor belt 17 and the 27 port of the collecting bin are controlled accordingly, so as to achieve precise and fast control effect.

One end of the partition plate 23 is hinged at the lower part of the left side wall of the collecting bin 27 , and the other end of the partition plate 23 is provided with a partition plate adsorption iron sheet 25 . When the control circuit controls the electromagnet 24 on the warehouse mouth to be energized, the clapboard adsorption iron sheet 25 is attached to the electromagnet 24 on the warehouse mouth, and the discharge port of the collecting bin 27 is closed; when the control circuit controls the electromagnet 26 under the warehouse mouth to be energized, The clapboard adsorption iron sheet 25 is attached to the electromagnet 26 under the bin opening, and the discharge port of the collecting bin 27 is opened, so that the pellets can be automatically discharged after reaching the specified quantity.

The above-mentioned control circuit is connected with the strong magnetic electromagnet 9, the weak magnetic electromagnet 13, the transmission motor 16, the infrared emitting tube 19, the infrared receiving tube 20, the upper electromagnet 24 at the warehouse mouth, the lower electromagnet 26 at the warehouse mouth, the display screen 21 and the keyboard 22. . The strong magnetic electromagnet 9 and the weak magnetic electromagnet 13 are used to control the movement of the asymmetric oscillating mechanism, so that the feeding hopper 3 generates different accelerations before and after under the action of the asymmetric electromagnetic force, thereby making the pellets oscillate under its own weight and the feeding hopper 3 under the action of a single-row distribution. The transmission motor 16 controls the movement of the conveying mechanism, so that the granules falling from the feeding mechanism enter the collecting mechanism. The infrared emitting tube 19 and the infrared receiving tube 20 are used for sub-packaging and counting the pellets. The upper electromagnet 24 and the lower electromagnet 26 of the silo are used to control the movement of the baffle 23 , thereby realizing the opening and closing of the discharge port of the collecting bin 27 . The display screen 21 is used to display the total count of pellets, the number of times of pellets being packed, and the current count of this dispensing. The button is used to set the quantity of a single sub-packaging, and the asymmetrical oscillation mechanism controls the movement state of the feeding hopper 3 by turning it on and off.

The minimum control system module of the control circuit uses AT89S52 as the main control chip, and uses 11.0592MHZ crystal oscillator to construct the minimum control system. Conveyor belt 17 drive motor 16 module uses a four-phase five-wire drive motor 1628BYJ48 as the power source of the system, and is matched with a drive circuit with L298N as the core to realize power transmission under the timing control of AT89S52.

The display screen 21 selects JLX12864G-086 as the display interface of the system, which mainly displays data information such as setting parameters and counting data. The keyboard 22 adopts a 4*4 matrix keyboard 22, which is connected to the P0 port of the AT89S52 and is connected with an external pull-up resistor. The control keyboard 22 is mainly used for data setting and related control operations on the system.

The asymmetric oscillation drive circuit includes diodes D9-D10, Darlington transistors Q1-Q2, and resistors R4-R5; the base of the Darlington transistor Q1 is connected to the output end of the controller through the resistor R4, and the Darlington transistor Q2 is connected to the output end of the controller. The base is connected to the output terminal of the controller through the resistor R5; the drain of the Darlington tube Q1 is divided into two channels, one is connected to the power supply Vcc through the diode D9, and the other end is connected to the power supply Vcc through the strong magnetic electromagnet 9; Darlington The drain of the transistor Q2 is divided into two channels, one is connected to the power supply Vcc through the diode D10, and the other end is connected to the power supply Vcc through the weak magnetic electromagnet 13; the source of the Darlington transistor Q1 and the source of the Darlington transistor Q2 Also connect to ground GND. See Figure 4. The asymmetric oscillating mechanism is composed of two symmetrical electromagnets E1 and E2, and the magnetism of E1 is stronger than that of E2. E1 and E2 are driven by NPN and PNP Darlington tubes respectively. The bases of the two Darlington tubes are connected in common and controlled by the PWM wave output by port P3.1 of AT89S52. This circuit structure enables the electromagnets E1 and E2 to be activated only at the same time, and under the control of the PWM wave, the electromagnetic oscillation structure "back and forth" expands and contracts. If the duty cycle α of the PWM wave is configured so that the start-up times of E1 and E2 in one cycle are different, the electromagnetic oscillation structure can make the pellets move at different speeds in the direction of E1. When α=1, the electromagnetic oscillating structure behaves as a balanced vibration, and the pellets move at the basic speed; when α>1, the electromagnetic oscillating structure behaves as a biased vibration toward E1, increasing the speed of the feeding hopper 3 moving toward E1, and the pellets are in the direction of E1. Under the action of inertia, the speed of moving towards E2 increases; when α < 1, the electromagnetic oscillating structure appears to vibrate toward E2, reducing the speed of feeding hopper 3 moving to E1, and the speed of pellets moving to E2 under the action of inertia decrease. And the larger |α-1| is, the more obvious the deflection of the electromagnetic oscillation structure is.

The infrared counter is composed of an infrared transmitting tube and an infrared receiving tube, and is installed at a position where the angle between the collecting bin 27 and the plane of the conveyor belt 17 is 45°. When the system is running, the infrared emitting tube emits infrared rays. When no pellets slide down the channel, the infrared receiving tube can receive the infrared normally and output a high level; if the pellets slip, the infrared is blocked, and the infrared receiving tube 20 cannot Receive infrared, output low level. Based on this principle, by counting the falling edge of the infrared receiver tube output, the number of pellets can be obtained to realize the counting function.

The drive circuit of the warehouse port includes diodes D11-D12, Darlington transistors Q3-Q4, and resistors R7-R8; the base of the Darlington transistor Q3 is connected to the output end of the controller through the resistor R7, and the base of the Darlington transistor Q4 is connected to the output end of the controller. The pole is connected to the output end of the controller through the resistor R8; the drain of the Darlington tube Q3 is divided into two channels, one is connected to the power supply Vcc through the diode D11, and the other end is connected to the power supply Vcc through the lower electromagnet 26 of the warehouse mouth; Darlington The drain of the transistor Q4 is divided into two channels, one is connected to the power supply Vcc through the diode D12, and the other end is connected to the power supply Vcc through the electromagnet 24 on the warehouse port; the source of the Darlington transistor Q3 and the source of the Darlington transistor Q4 Also connect to ground GND. See Figure 5. The control of the discharge port of the collecting bin 27 is composed of two symmetrical electromagnets E3 and E4, which are driven by NPN and PNP Darlington tubes respectively. The bases of the two Darlington tubes are connected together, and are connected by P1. mouth control. When P1.4 outputs a high level, E3 starts, E4 stops, the partition 23 moves to E3, and the warehouse mouth opens; when P1.4 outputs a low level, E3 stops, E4 starts, the partition 23 moves to E4, and the warehouse mouth closure.

When using this dispensing machine, turn on the power switch of the control circuit, and set the number of dispensing times and the number of single dispensing by pressing the button. Rotate the chamfered surface of the lower end of the hopper 2 to the position coincident with the feeding hopper 3, and then pour the granular materials to be divided into the hopper 2. The pellets fall from the hopper 2 to the feeding hopper 3, and the pellets are initially arranged. Under the action of the asymmetrical oscillation mechanism, the granules move towards the conveyor belt 17 in the oscillation by inertia. The moving conveyor belt 17 distributes the pellets falling at different times at different positions on the conveyor belt 17, so that there is a certain distance between adjacent pellets. When the pellets fall from the right end of the conveyor belt 17 to the feeding port of the aggregate bin 27, the falling pellets block the infrared receiver tube to receive the infrared rays emitted by the infrared emission tube, and the infrared counter captures the pellet signal, and the current time The dispensing count is incremented and displayed on the display 21 . When the current count value reaches the set value for a single dispensing, the strong magnetic electromagnet 9 and the weak magnetic electromagnet 13 in the asymmetric oscillation mechanism are powered off, the transmission motor 16 of the conveyor belt 17 is powered off, and the electromagnet 24 on the warehouse port is powered off. The electromagnet 26 under the silo mouth is energized, and the separator 23 moves downward around the rotating shaft of the separator 23 under the action of gravity and electromagnetic attraction, and is adsorbed on the electromagnet 26 under the silo mouth, and the discharge port of the collecting bin 27 Open, the pellets fall from the collection bin 27 into the outer container. After the pellets are discharged from the warehouse, the strong magnetic electromagnet 9 and the weak magnetic electromagnet 13 in the asymmetric oscillation mechanism are energized, the transmission motor 16 of the conveyor belt 17 is energized, the upper electromagnet 24 at the warehouse mouth is energized, the lower electromagnet 26 is de-energized, and the partition plate 23 is energized. Under the action of the magnetic force, it moves upwards around the rotating shaft of the partition plate 23, and is adsorbed on the electromagnet 24 on the bin opening, and the discharge port of the collecting bin 27 is closed and the next count is performed. When the number of dispensing times reaches the set number of dispensing times, the system stops working.
