[0029] Among them, a cover plate 103 is fixedly installed at one end of the operating table 1, and the cover plate 103 covers the outer surface of the motor 203. The motor 203 is fixedly installed at one end of the operating table 1, and the output shaft passes through the operating table 1 and is connected to the transmission column in the L-shaped conveyor belt 2.

[0030] A first gear 201 and a second gear 202 are fixedly mounted on one end of the transmission column in the two groups of L-shaped conveyor belts 2. The first gear 201 and the second gear 202 are flush and can engage with the pressing mechanism 3. The first gear 201 and the second gear 202 are located in the cover plate 103.

It will be detected by the filling port 101 and the ultrasonic distance sensor 102 in the connecting port. The ultrasonic distance sensor 102 measures the position of the bill by emitting ultrasonic waves and receiving reflected waves, thereby estimating the center position of the bill. If the bill is long, it will be transported out from the connecting port, so that it can adapt to different lengths. When the center of the bill is detected by the L-shaped conveyor belt 2 and is in the center of the operating table 1, a signal is sent to the controller, and the controller controls the pushing mechanism 3 to move vertically downward, thereby being able to push the center of the bill into the folding slot between the two sets of L-shaped conveyor belts 2, and as the pushing mechanism 3 continues to press downward, it can be meshed with the first gear 201 and the second gear 202 at one end of the transmission column in the two sets of L-shaped conveyor belts 2 for transmission, thereby being able to use the transmission column to drive the two sets of L-shaped conveyor belts 2 to rotate relative to each other toward the center, thereby being able to continue to fold the bill located in the bill voucher folding slot and transmit it to the discharge outlet 104 to fall out, and in the process of the bill being transmitted from the bill voucher folding slot, the bill is folded, and the folded portion is the center of the bill;

[0034] When the first group of bills is pushed into the bill voucher folding port, the tail end of the bill will also be pulled into the filling port 101 to provide a position for filling the next group of bills, and at this time the conveying direction of the L-shaped conveyor belt 2 is also toward the center, so that another group of bills can also be conveyed into the filling port 101, until the head of the bill is conveyed to the center of the operating table 1 and then it will be blocked at one end by the pressing mechanism 3, until the folded bill is discharged from the discharge port 104, the pressing mechanism 3 will be lifted up again to allow the new bill to pass through it and be detected by the two groups of ultrasonic distance sensors 102. The center can then be pressed into the bill voucher folding port again by the pressing mechanism 3 to complete the continuous folding, thereby improving the efficiency of bill processing.

[0035] like Figure 4-Figure 5 As shown, the pushing mechanism 3 includes an electric push rod 301, which is fixedly mounted on the inner upper surface of the operating table 1 and flush with the discharge port 104. The electric push rod 301 is controlled by the controller. A pushing rod 302 is fixedly mounted on one end of the piston rod of the electric push rod 301. The pushing rod 302 can be inserted into the folding opening of the bill voucher between the two groups of L-shaped conveyor belts 2.

[0036] A guide groove 303 is provided at one end of the pushing rod 302, a sliding column is fixedly installed in the guide groove 303, a guide block 306 is slidably installed on the outer surface of the sliding column in the guide groove 303, and two groups of third gears 304 are rotatably installed at one end of the guide block 306. The two groups of third gears 304 are meshed with each other, and the third gears 304 are located in the discharge outlet 104 through the guide block 306.

[0037] The two sets of third gears 304 can be pushed by the electric push rod 301 to engage with the first gear 201 and the second gear 202 respectively;

[0038] The outer surface of the sliding column in the guide groove 303 is sheathed with a spring 305 , and the upper and lower surfaces of the spring 305 are respectively in contact between the inner upper surface of the guide groove 303 and the upper surface of the guide block 306 .

[0039] Through the design of the electric push rod 301, the pushing rod 302, the third gear 304, the guide block 306 and the spring 305, the center position of the bill is detected by the ultrasonic distance sensor 102 and is in the center of the operating table 1. After that, a signal is sent to the controller, and the controller controls the electric push rod 301 to push the pushing rod 302 to move vertically downward, so that the pushing rod 302 can insert the top of the bill into the folding groove between the two groups of L-shaped conveyor belts 2, and as the pushing rod 302 is continuously pressed downward, it can drive the two groups of third gears 304 on one side to engage with the first gear 201 and the second gear 202 at one end of the transmission column in the two groups of L-shaped conveyor belts 2 for transmission, and the third gear 304 is meshed with the first gear 201 and the second gear 202 at one end of the transmission column in the two groups of L-shaped conveyor belts 2 for transmission. The second gear 202 is meshed with the second gear 202, and the pushing rod 302 is continuously pressed down. During the continuous downward pressure, the third gear 304 will slide in the guide groove 303 of the pushing rod 302 through the guide block 306, and at the same time will press one end of the spring 305. The spring 305 will apply a force to the guide block 306, thereby enabling the guide block 306 to drive the third gear 304 to mesh with the first gear 201 and the second gear 202 through the elastic force, thereby enabling the transmission column of the other set of L-shaped conveyor belts 2 driven by the transmission column of the motor 203 to rotate, thereby enabling the two sets of L-shaped conveyor belts 2 to rotate relative to each other toward the center, thereby enabling the bill located in the bill voucher folding opening to continue to fold. The folded bill is transmitted to the discharge port 104 and falls out. In the process of the bill being transmitted from the bill voucher folding port, the center part of the bill is folded. In the folding process, the controller will judge the progress of the bill folding according to the length of the bill and the speed of the motor 203. When the controller judges that the bill is folded and discharged from the discharge port 104, it will start the electric push rod 301 again to pull the pushing rod 302 out of the bill voucher folding port, and at the same time drive the two sets of third gears 304 to disengage from the engagement with the first gear 201 and the second gear 202, so that only the L-shaped conveyor belt 2 in the filling port 101 can be driven inward for the staff to fill in another set of bills. If the first set of bills has not been completely folded, The tail end of the bill will be pulled into the filling port 101 to provide a position for the next group of bills to be filled, and at this time the conveying direction of the L-shaped conveyor belt 2 in the filling port 101 is also conveyed toward the center, so that another group of bills can be conveyed into the filling port 101, until the head of the bill is conveyed to the center of the operating table 1 and is blocked at one end by the pushing rod 302, until the folded bill is discharged from the discharge port 104, the pushing rod 302 will be pulled up again to allow a new bill to pass through it and be detected by the two sets of ultrasonic distance sensors 102. The center can then be pressed into the bill voucher folding port by the pushing rod 302 again to complete the continuous folding, thereby improving the efficiency of bill processing.

[0040] According to the above technical solution, the working steps of this solution are summarized and sorted out: when folding the bill, the bill can be filled into the upper surface of the L-shaped conveyor belt 2 in the filling port 101, and the L-shaped conveyor belt 2 will be driven by the motor 203, so that the L-shaped conveyor belt 2 can drive the bill to be transported into the operating table 1, until it is transported into the connecting port at the other end by the L-shaped conveyor belt 2, and is detected by the ultrasonic distance sensor 102 in the filling port 101 and the connecting port. The ultrasonic distance sensor 102 measures the position of the bill by emitting ultrasonic waves and receiving reflected waves, thereby estimating the center position of the bill. When the center of the bill is detected by the L-shaped conveyor belt 2 and is in the center of the operating table 1, a signal is sent to the controller, and the controller The electric push rod 301 will be controlled to push the pushing rod 302 to move vertically downward, so that the pushing rod 302 can insert the bill into the folding notch between the two groups of L-shaped conveyor belts 2, and as the pushing rod 302 continues to press downward, it can drive the two groups of third gears 304 on one side to engage with the first gear 201 and the second gear 202 at one end of the transmission column in the two groups of L-shaped conveyor belts 2 for transmission, and the pushing rod 302 will be continuously pressed downward during the process of the third gear 304 engaging with the first gear 201 and the second gear 202. During the continuous downward pressure, the third gear 304 will slide and shrink in the guide groove 303 of the pushing rod 302 through the guide block 306, and at the same time will press on one end of the spring 305, and the spring 305 will press the guide The block 306 applies a force, which enables the guide block 306 to drive the third gear 304 to mesh with the first gear 201 and the second gear 202 through elastic force, so that the transmission column of the motor 203 can drive the transmission column of the other set of L-shaped conveyor belts 2 to rotate, so that the two sets of L-shaped conveyor belts 2 can rotate relative to each other toward the center, so that the bill located in the bill folding port can be further folded and transmitted to the discharge port 104 to fall out. In the process of the bill being transmitted from the bill folding port, the bill is folded. In the folding process, the controller will judge the progress of the bill folding according to the length of the bill and the speed of the motor 203. When the controller determines that the bill is folded and discharged from the discharge port 104, it will The electric push rod 301 is started again to pull the pushing rod 302 out of the bill voucher folding port, and at the same time, the two sets of third gears 304 are disengaged from the first gear 201 and the second gear 202, so that the L-shaped conveyor belt 2 in the filling port 101 can only be transmitted inwardly for the staff to fill another set of bills. If the first set of bills has not been completely folded, the tail end of the bill will also be pulled into the filling port 101 to provide a position for the filling of the next set of bills. At this time, the conveying direction of the L-shaped conveyor belt 2 in the filling port 101 is also conveyed toward the center, so that another set of bills can be conveyed into the filling port 101 until the head of the bill is conveyed to the center of the operating table 1 and is blocked at one end by the pushing rod 302.After the folded bill is discharged from the discharge port 104, the push rod 302 will be pulled up again to allow a new bill to pass through. When the center is detected by the two sets of ultrasonic distance sensors 102, the push rod 302 can be pushed into the bill folding port again to complete the continuous folding process, thereby improving the efficiency of bill processing.

[0041] In summary: it enables the folding of bills of different lengths, and can handle bills of different lengths without frequent adjustment or replacement of equipment, thereby improving operational flexibility. In the folding process, it can also automatically determine the center part of the bill for folding to ensure the symmetry and consistency of the folding process, thereby improving the appearance and quality of the bill.
