The working principle of the present utility model is as follows:

For 5 hair, 1 hair and 1 piece coins, we can use the difference in diameter to classify them. According to the principle of mechanical vibration resonance, the natural frequency w ₁ of the feeding unit 1 is tuned to be close to the electromagnetic excitation frequency w ₂ , so that the ratio z = 0.85 to 0.95, the machine will work in a low critical resonance state. Stable work and low power consumption.

Specifically, the current sent to the electromagnetic coil of the electromagnet 23 is generally rectified by single-phase half-wave. When it is not rectified, the voltage is sinusoidal. After half-wave rectification, a voltage is applied to the electromagnetic coil in the positive half cycle. Therefore, the electromagnetic coil has a current passing through, and a pair of pulse powers of equal size are generated between the armature 21 and the iron core, which attract each other. At this time, the feeding tray body 12 moves downward and presses the spring sheet 24 with a certain angle downward, so that the feeding tray body 12 makes a slight rotational movement around the central axis, the spring sheet 24 is deformed, and a certain potential energy is stored. In the negative half cycle, there is no current in the electromagnetic coil, and the electromagnetic force disappears. Since the potential energy stored by the spring sheet 24 is released, the armature 21 and the iron core move away in the opposite direction, and the feeding disc body 12 moves upward and rotates in the opposite direction around the central axis. . In this way, the feed tray body 12 vibrates at the frequency of the AC power source. Since there is a certain angle between the screw conveying channel 11 and the action line of the exciting force, when the vertical component of the vibration acceleration of the feeding tray body 12 is greater than the gravitational acceleration, the coins in the feeding tray body 12 are continuously tossed up and follow the trajectory of the parabola. Jump forward. Since the vibration frequency of the feeding tray body 12 is very high, the amplitude is very small, and the height of the coin being thrown is also very small, so only the coin can be seen moving in a forward direction in the screw conveying channel 11 .

In the process of coin sorting, a hole with a slightly larger diameter coin is drilled on the screw conveying channel 11. Since the diameter of a coin is larger than that of a fifty cent coin, the diameter of one cent coin is greater than that of a one cent coin. Therefore, on the path of the screw conveying channel 11, first Drill a hole that allows a 10-cent coin to fall, but a 5-cent coin and a piece of coin can move normally. Then, drill a hole with a slightly larger diameter for the 5-cent coin at a certain distance to facilitate the falling of the 5-cent coin. The latter is on the screw conveying channel 11. The moving coin has only one coin, thus achieving the purpose of coin classification.

At the same time, a collection unit 3 is designed under the first to third blanking holes (101-103) respectively. Using photoelectric sensors and a small circuit control system, when the device senses that the number of coins reaches 50, the machine will Stop, then, the motor 36 rotates to drive the coins out, and at the same time, another empty collection bucket 32 is placed in place, the machine starts again, and people can take out the coins and pack them quickly.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.

The above-mentioned embodiments only represent several embodiments of the present application, but should not be construed as limiting the scope of the present application. It should be pointed out that for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the scope of protection of the patent of the present application shall be subject to the appended claims.
