[0022] Example 1

[0023] This embodiment provides a convenient coin pressing machine, such as Figure 1-3 As shown, the coin maker comprises a base 1, side plates 2 arranged opposite to each other, a top frame 11 arranged on the top of the side plates 2, and a driving mechanism, a coin pressing mechanism, a feeding mechanism and a conveying mechanism. The top frame 11 is fixed to the top of the side plates 2 by bolts 17.

[0024] The driving mechanism is disposed on one side of the side plate 2, and includes a motor 14, a first gear 13, a second gear 7, a groove wheel 3 and a dial 4. The output end of the motor 14 is connected to the first gear 13, the first gear 13 is meshed with the second gear 7, and the dial 4 is coaxially fixed with the second gear 7 and cooperates with the groove wheel 3 to drive the groove wheel 3 to rotate.

[0025] The second gear 7 is connected to the feeding mechanism, and the groove wheel 3 is connected to the coin pressing mechanism and the transmission mechanism. The coin pressing mechanism is detachably arranged between the side plates 2 and is located below the feeding mechanism. The transmission mechanism is arranged below the coin pressing mechanism.

[0026] Working principle:

[0027] The motor 14 is started, and the motor 14 drives the first gear 13 to rotate, and the first gear 13 drives the second gear 7 to rotate, and then drives the dial 4 to rotate. The dial 4 drives the groove wheel 3 to rotate a quarter of a turn each time, and then drives the coin pressing mechanism and the conveying mechanism to press and convey coins respectively. At the same time, the dial 4 drives the feeding mechanism to convey coins 6 to the coin pressing mechanism.

[0028] Example 2

[0029] This embodiment provides a specific implementation of each mechanism of the coin press based on the embodiment 1.

[0030] like Figure 1-3 As shown, the feeding mechanism includes a connecting rod 5, a coin pressing rod 12, a pressing plate 18 and a coin slot 10.

[0031] Specifically, the pressing plate 18 is arranged on the top of the side plate 2, and the coin slot 10 and the coin 6 arranged therein are arranged on the top of the pressing plate 18. One end of the connecting rod 5 is rotatably connected to the outside of the dial 4, and the other end is rotatably connected to the coin pressing rod 12. The two ends of the coin pressing rod 12 respectively penetrate the guide grooves on both sides of the top frame 11, and the guide grooves are provided with guide rods; the coin pressing rod 12 is nested in the guide grooves and moves up and down along the guide grooves. The coin pressing rod 12 is provided with a paddle, and the paddle is located above the coin slot 10.

[0032] Furthermore, in the present embodiment, the bottom of the coin slot 10 is tilted so that it is lower at the front and higher at the back, and a notch is provided at the front end of the bottom so that the coin 6 can fall into the coin pressing mechanism.

[0033] The coin pressing mechanism includes two embossing disks 9 and two first rotating shafts 16 .

[0034] Specifically, the first rotating shaft 16 is rotatably connected to the side plates 2 via the bearing 15 , and the embossing disc 9 is relatively disposed between the side plates 2 via the first rotating shaft 16 .

[0035] Furthermore, the groove wheel 3 is arranged on the outer side of the side plate 2 and is fixedly connected to any one of the first rotating shafts 16 to drive one of the first rotating shafts 16 to rotate.

[0036] Furthermore, one end of each first rotating shaft 16 close to the motor 14 is fixedly connected to the third gear 19, and the third gears 19 are respectively meshed and connected to the fourth gears, and the two fourth gears are meshed and connected. In this embodiment, the groove wheel 3 is used to first drive a third gear 19 to rotate, and the third gear 19 drives the meshed fourth gear to rotate, thereby causing another fourth gear to rotate, and the fourth gear drives another meshed third gear 19 to rotate. At the same time, the two third gears 19 rotate in opposite directions, thereby causing the two embossing disks 9 to rotate relative to each other to press coins.

[0037] Furthermore, the embossing disc 9 is detachably mounted on the first rotating shaft 16, so as to facilitate the replacement of the embossing type.

[0038] The conveying mechanism includes a conveyor belt 8 , a belt 20 and a second rotating shaft 21 .

[0039] Specifically, the second rotating shaft is located between the side plates and is rotatably connected to the side plates 2. A pulley is provided on the second rotating shaft 21 close to the groove wheel 3, one end of the belt 20 is sleeved on the pulley, and the other end is sleeved on the first rotating shaft 16 connected to the groove wheel 3. The conveyor belt 8 is transmission-connected to the second rotating shaft 21 and is located below the embossing disk 9.

[0040] In this embodiment, the first rotating shaft 16 rotates to drive the belt 20 to rotate, and then drives the second rotating shaft 21 to rotate, thereby realizing the movement of the conveyor belt 8.

[0041] Working principle:

[0042] Start the motor 14 to drive the dial 4 to rotate. The dial 4 drives the connecting rod 5 to rotate, so that the coin pressing rod 12 moves up and down along the guide groove to realize intermittent coin dialing 6. At the same time, the dial 4 drives the groove wheel 3 to rotate a quarter of a circle each time, and the first rotating shaft 16 rotates accordingly, and then the embossing disk also rotates a quarter, which is just enough to press a coin once. When a coin is pressed down, the coin is moved forward by the coin pressing rod 12, and then the next coin is pressed down. The conveyor belt 8 is driven by the belt 20 and the second rotating shaft 21, so that the conveyor belt 8 moves forward a certain distance after pressing a coin, thereby realizing coin recovery.
