The opening size of the qualified opening increases successively with the transportation direction of the compression conveyor belt, and the collecting box and the qualified opening correspond one to one and are connected to the inner wall of the qualified opening. The control component is connected to the inner wall of the unloading channel facing the discharge end of the loading tray, and the control component can measure the size of the coin and whether it is defective. The opening and closing component is connected to the inner wall of the defective opening, and the opening and closing component is electrically connected to the control component. The control component can control the operation of the opening and closing component, and the opening and closing component can control the on and off of the defective opening.

[0007] By adopting the above technical solution, the staff places the coins on the surface of the conveyor belt, and the conveyor belt transports the coins to the feeding end of the loading tray. The surface of the loading tray is used for scattering the coins, and the coins on the surface of the loading tray are discharged one by one from the discharging end of the loading tray into the unloading channel. The conveyor belt surface and the base surface are pressed to clamp the two sides of the coins and drive the coins away from the loading tray. The control component measures the size and whether there are defects on the coins in the unloading channel in turn. When the control component detects that the coin is defective, it controls the opening and closing component to operate, and the opening and closing component opens the defective port. The defective coin enters the inner cavity of the collection box through the defective port, thereby realizing the collection of the defective coins. At the same time, other coins enter the collection box from the corresponding qualified port according to their own size, thereby realizing the sorting of coins of different sizes. There is no need for staff to perform secondary sorting on the classified coins, thereby shortening the coin detection cycle and reducing the coin detection cost.

[0008] Optionally, the opening and closing component includes an opening and closing plate and an opening and closing cylinder, the opening and closing cylinder is connected to the inner wall of the defective port, and the opening and closing plate is connected to the end of the piston rod of the opening and closing cylinder. When the piston rod of the opening and closing cylinder is extended, the opening and closing plate surface is pressed against the inner wall of the defective port and separates the defective port and the unloading channel. The control component includes a controller and a Cs sensor. The Cs sensor is connected to the inner wall of the unloading channel facing the discharge end of the loading tray. The Cs sensor can measure the size of the coin and whether it is defective. The controller is connected between the Cs sensor and the opening and closing cylinder. The controller is used to receive the detection value of the Cs sensor and control the operation of the opening and closing cylinder.

[0009] By adopting the above technical solution, when the coins in the loading tray are discharged from the discharge end of the loading tray in sequence, the Cs sensor accurately detects the size and whether the coins in the discharge channel are damaged, and sends the value to the controller. The controller compares the value with the preset value and controls the operation of the opening and closing cylinder to open the defective port in a targeted manner, thereby realizing accurate sorting of defective and qualified products, eliminating the need for staff to perform secondary sorting, thereby improving the coin sorting efficiency.

The driving belt is tensioned and connected to the two driving wheels, and multiple compression wheels are rotatably connected to the base surface at intervals. The wheel surface of the compression wheel engages with the tooth surface of the driving belt, and the surface of the driving belt and the surface of the base press the two sides of the coin and drive the coin to move.

[0011] By adopting the above technical solution, when the drive motor is running, one of the drive wheels is coaxially connected to the motor shaft of the drive motor, and the other drive wheel is rotatably connected to the surface of the base. The drive belt is tensioned and connected to the two drive wheels, and multiple pressure wheels are rotatably connected to the surface of the base at intervals. The pressure wheel surface engages with the tooth surface of the drive belt, driving the drive belt between the two drive wheels to remain taut. The drive belt surface and the base surface press the two sides of the coin and drive the coin to move, thereby ensuring stable transportation of the coin.

[0012] Optionally, the base is connected to a plurality of heat dissipation components, which correspond to the qualified ports one by one and are connected to the inner wall of the qualified ports, the heat dissipation components include a piston, a one-way valve 1 and a one-way valve 2, the surface of the base facing the driving belt is provided with a heat dissipation channel for the piston to slide, the one-way valve 1 is connected to the inner wall of the heat dissipation channel close to the discharge channel, the one-way valve 1 allows outside air to enter the heat dissipation channel, the inner wall of the qualified port is provided with an outlet flow channel, the outlet flow channel is connected to the heat dissipation flow channel, the surface of the collection box facing the outlet flow channel is provided with an air inlet, the air inlet is connected to the inner cavity of the collection box, the one-way valve 2 is connected to the inner wall of the outlet flow channel, and the one-way valve 2 supplies air in the outlet flow channel into the inner cavity of the collection box through the air inlet.

[0013] By adopting the above technical solution, when the piston slides along the inner wall of the heat dissipation channel toward the direction of the feeding channel, the air pressure in the heat dissipation channel increases, and the air in the heat dissipation channel passes through the outlet channel and the air inlet in turn and enters the inner cavity of the collection box. The air impacts the coins in the collection box, driving the impurities on the surface of the coins in the collection box to be discharged from the collection box and impact the surface of the drive belt, thereby realizing preliminary cleaning of the coins in the collection box; at the same time, when the piston slides along the inner wall of the heat dissipation channel toward the direction away from the feeding channel, the air pressure in the heat dissipation channel decreases, driving the outside air to enter the heat dissipation channel through the one-way valve, thereby realizing the replenishment of the air in the heat dissipation channel, and at the same time, the heat dissipation channel faces the surface of the drive belt, driving the air flow on the surface of the drive belt, and the air is in full contact with the drive belt and performs heat exchange, thereby realizing cooling of the drive belt, making it difficult for the drive belt to heat up during long-term operation, thereby ensuring the stability of the coin detection equipment.

[0014] Optionally, a filter is connected to the inner wall of the heat dissipation channel facing the feed end of the one-way valve, and the outside air enters the one-way valve after being filtered by the filter.

[0015] By adopting the above technical solution, the outside air is filtered through the filter and then enters the one-way valve 1, so that the one-way valve 1 is not easily blocked by impurities, thereby ensuring the stability of the one-way valve 1 operation.

[0017] By adopting the above technical solution, when air passes through the filter and enters the one-way valve, impurities accumulate on the surface of the filter. The filter slides along the inner wall of the cleaning chamber toward the heat dissipation channel due to the pressure of the impurities. The synchronous belt between the two synchronous wheels remains taut. One of the synchronous wheels is connected to the rotating shaft of the driving wheel, and the other synchronous wheel is coaxially connected to the rotating shaft of the cleaning impeller, driving the cleaning impeller to rotate on the cleaning plate surface. The air outlet end of the cleaning impeller faces the surface of the filter, driving impurities away from the surface of the filter, thereby realizing directional cleaning of the filter surface.

[0018] Optionally, the base is connected to a power assembly, which includes an elastic member 2, a transmission rod, a clamping rod and a cam. The surface of the base facing the synchronous wheel is provided with a power cavity for the clamping rod to slide, and the power cavity and the heat dissipation channel both pass through the outer wall of the base.

[0019] By adopting the above technical solution, the cam has a large end and a small end, and the elastic force of the second elastic member drives the surface of the clamping rod to roll in contact with the surface of the cam wheel. When the surface of the clamping rod abuts the large end of the cam, it drives the piston to slide in the direction close to the one-way valve one. When the surface of the clamping rod abuts the small end of the cam, it drives the piston to slide in the direction away from the one-way valve one, thereby realizing the back and forth sliding of the piston on the inner wall of the heat dissipation channel. No external power device is required to drive the piston to slide, thereby reducing energy loss and embodying the concept of energy saving.

[0020] Optionally, the clamping rod includes a clamping portion and a roller, one end of the clamping portion is connected to the rod surface of the transmission rod, and the other end of the clamping portion is rotatably connected to the roller rotating shaft, and the roller surface tends to roll in contact with the cam wheel surface.

[0021] By adopting the above technical solution, the roller surface and the cam wheel surface are in rolling contact, sliding friction replaces rolling friction, reducing the wear between the pressing rod and the cam, thereby extending the service life of the coin detection equipment.
