[0059] The following is a preferred embodiment of the automatic passport issuance device provided by the utility model that can solve the above technical problems.

[0060] Please refer to Figure 1The preferred embodiment of the utility model provides a passport automatic issuing device, which includes a carrying mechanism 1, a pushing mechanism 2 and a limiting mechanism 3.

[0061] Please refer to Figure 1 , Figure 2 and Figure 5 The carrying mechanism 1 includes a bottom plate 11 and a delivery box 12. A channel 111 extending in the transverse direction is provided on the bottom plate 11. The two sides of the channel 111 are respectively a first side 1111 and a second side 1112. The two ends of the channel 111 are respectively a first end 1113 and a second end 1114. The delivery box 12 is provided on the bottom plate 11. The delivery box 12 is square. The two plates in the transverse direction of the delivery box 12 are respectively a first plate 121 and a second plate 122. The second plate 122 is closer to the second end 1114 relative to the first plate 121. The bottom edge of the second plate 122 includes a horizontal section 1221 and an inclined section 1222, both of which are higher than the top surface of the bottom plate 11. The horizontal section 1221 is parallel to the top surface of the bottom plate 11 and is located at the channel 111 and the first side 1111. The inclined section 1222 is inclined upward to the top surface of the bottom plate 11 and is located at the second side 1112.

[0062] Please refer to Figure 2 The pushing mechanism 2 includes a pushing head 21, a tension spring 22, a sliding block 23 and a pushing driving assembly 24. The sliding block 23 is slidably connected to the bottom plate 11 and is arranged to slide in the horizontal direction. The pushing head 21 is rotationally connected to the sliding block 23 and is located in the channel 111. The tension spring 22 is connected between the sliding block 23 and the pushing head 21 to provide elastic force so that the top of the pushing head 21 protrudes upward from the top surface of the bottom plate 11. The pushing driving assembly 24 is connected to the sliding block 23 to drive the sliding block 23 and the pushing head 21 to move in the horizontal direction.

[0063] Please refer to Figure 1 and Figure 6 The limiting mechanism 3 is connected to the hair box 12, and the limiting mechanism 3 includes a bearing 31, and the bearing 31 is arranged between the horizontal section 1221 and the bottom plate 11.

[0064] The automatic passport issuing device of the utility model can be used to place a stack of passports on the bottom plate 11 located inside the issuing box 12. The passport is divided into two parts. The thicker half is located at the channel 111 and the first side 1111, and the thinner and tilted other half is located at the second side 1112. The folding line of the passport is consistent with the direction of the channel 111. In the initial state, the push head 21 is located on the side of the passport close to the first end 1113. The tension spring 22 pulls the push head 21 to protrude from the bottom plate 11, and the push driving component 24 drives the push head 21 to move toward the direction close to the second end 1114. The passport booklet at the bottom is pushed out from the bottom of the second plate 122, the thicker half of the passport booklet is pushed out from the horizontal section 1221, and the thinner and tilted other half is pushed out from the inclined section 1222. When the thicker half passes under the bearing 31, the bearing 31 is limited to allow only the lowest passport booklet to pass through each time. After completing one booklet pushing, the pusher head 21 moves toward the direction close to the first end 1113. At this time, the pusher head 21 is turned downward by the force of the passport booklet and is located under the passport booklet. It returns to the side of the passport booklet close to the first end 1113 again and continues to push out the passport booklet one by one. The automatic passport issuing device of the utility model can load multiple passport books at one time through the mutual cooperation of the carrying mechanism 1, the booklet pushing mechanism 2 and the limiting mechanism 3, and automatically push the passport books one by one to the printing device connected thereto, saving manpower and effectively improving work efficiency.

[0065] Please refer to Figure 2 The side of the push head 21 facing the first end 1113 is an arc surface, which facilitates the push head 21 to pass under the passport.

[0066] A reflective sensor is installed on one side of the bottom plate 11 to detect whether there is a passport. After the software obtains the signal, it is fed back to the operator through human-machine exchange to replenish the passport in time.

[0067] Please continue to refer to Figure 2 , a lower guide wheel 112 is provided on the bottom plate 11, the axial direction of the lower guide wheel 112 is longitudinal, and the top thereof protrudes from the top surface of the bottom plate 11. By arranging the lower guide wheel 112, it helps the passport to slide forward.

[0068] Please refer to Figure 1The carrying mechanism 1 also includes a ramp structure 13, which is arranged on the bottom plate 11, and is located in the book box 12, and is located at the second side 1112. The top surface of the ramp structure 13 is inclined to the bottom plate 11, and it gradually increases from the end close to the channel 111 to the end away from the channel 111. The inclined section 1222 is higher than the top surface of the ramp structure 13 as a whole. The angle of the ramp structure 13 is adapted to the natural angle of the passport book when it is spread out. By setting the ramp structure 13, the book can be kept at the best angle when it is spread out, avoiding the spread angle of the passport book being too large, causing the thicker half to tilt up, resulting in the push head 21 not being able to fully contact the thicker half of the passport book, affecting normal transportation.

[0069] Please continue to refer to Figure 1 The slope structure 13 is connected to the first plate 121 and is spaced apart from the second plate 122. When placing a passport, the passport can be placed against the first plate 121, and the thinner half has one end supported by the slope structure 13, and the other end can be in a naturally hanging state, so that it is easy to go out from under the inclined section 1222.

[0070] Please refer to Figure 1 and Figure 4 , the top of the book box 12 is open, and a side plate of the book box 12 in the longitudinal direction is provided with a notch 123. The carrying mechanism 1 also includes a book pressing plate 14, which is movably arranged in the book box 12 in the vertical direction, and an upper guide wheel 142 is provided at the bottom of the book pressing plate 14, and the upper guide wheel 142 protrudes from the bottom surface of the book pressing plate 14, and a handle 141 is provided at the top of the book pressing plate 14, and the handle 141 extends longitudinally into the notch 123. The book pressing plate 14 is made of POM material, and the self-lubricating property of the POM material is utilized to ensure the guidance of the passport book and protect the important pages of the passport book from damage. With the above structure, a stack of passport books can be placed in the book box 12 through the opening at the top, and then the book pressing plate 14 is placed, and the handle 141 is held to move the book pressing plate 14 downward, so that the book pressing plate 14 presses the passport book, and when the push head 21 pushes the passport book below, the passport book will not shift upward, so that the passport book is transported smoothly.

[0071] Please refer to Figure 2 and Figure 3The push-type drive assembly 24 includes a stepper motor 241, a driving wheel 242, a driven wheel 243, a synchronous belt 244 and a push-type screw rod 245. The push-type screw rod 245 is arranged on the bottom surface of the bottom plate 11 and is arranged in the horizontal direction. The sliding block 23 is connected with the nut of the push-type screw rod 245. The stepper motor 241 is arranged on the top surface of the bottom plate 11 and is located outside the first plate 121. The driving wheel 242 is connected with the rotating shaft of the stepper motor 241, the driven wheel 243 is connected with the transmission rod of the push-type screw rod 245, and the synchronous belt 244 is sleeved on the driving wheel 242 and the driven wheel 243. In the above structure, a stepper motor 241 is used as the original power, and a synchronous belt 244 is used as a first-level buffer and shock absorption. The stepper motor 241 rotates forward and reversely in a cycle, driving the synchronous belt 244 and the transmission rod of the push screw 245 to rotate forward and reverse, and driving the nut, sliding block 23 and push head 21 of the push screw 245 to reciprocate in the horizontal direction. The above structure allows the push head 21 to push the passport to maintain stability. The length of the movement route, the starting position, and the end position are controlled by two micro sensors to control the motor signal on and off, which is convenient for the control personnel to write programs.

[0072] Please refer to Figure 6 The limiting mechanism 3 further includes a fixed block 32 and a moving block 33. The fixed block 32 is fixed to the outer surface of the second plate 122. A limiting groove 321 is provided on the fixed block 32. The moving block 33 is arranged in the limiting groove 321. The moving block 33 is provided with an elongated hole 331 extending in the vertical direction. The moving block 33 is detachably connected to the fixed block 32 by screws passing through the elongated hole 331. The bearing 31 is connected to the bottom of the moving block 33. In the above structure, the position of the screw in the elongated hole 331 can be changed, thereby changing the position where the moving block 33 is installed on the fixed block 32. When the passport is thicker, the moving block 33 can be installed at a high point, so that the distance between the bearing 31 and the bottom plate 11 is larger; when the passport is thinner, the moving block 33 can be installed at a low point, so that the distance between the bearing 31 and the bottom plate 11 is smaller. By providing the limiting groove 321 on the fixed block 32 and installing the moving block 33 in the limiting groove 321, the installation process is simple.

[0073] Please refer to Figure 1 and Figure 7The automatic passport issuing device also includes a kinetic energy pressing mechanism 4, which is located on the outside of the second plate 122. The kinetic energy pressing mechanism 4 includes a pressing guide wheel 41 and a pressing drive assembly 42. The pressing guide wheel 41 is vertically movable and arranged above the bottom plate 11, and is located at the second side 1112. The axial direction of the pressing guide wheel 41 is longitudinal. The pressing drive assembly 42 is connected to the pressing guide wheel 41, and is used to drive the pressing guide wheel 41 to move vertically. When the tilted half of the passport comes out from the bottom of the inclined section 1222 and passes under the pressing guide wheel 41, the pressing guide wheel 41 moves downward, is tangent to the tilted half of the passport, and presses it downward, so that the passport is in a flattened state. When the tilted half of the passport leaves the pressing guide wheel 41, the pressing guide wheel 41 moves upward to reset, and repeats the cycle. With the above structure, the passport can be in a flattened state to meet the needs of the printing device. The kinetic energy pressing mechanism 4 is also provided with two upper and lower micro sensors to control the upper and lower stopping positions of the pressing guide wheel 41 .

[0074] Please refer to Figure 1 and Figure 2The automatic passport issuing device further includes a first guide member 5 and a second guide member 6.

A gap is provided between the guide plate 51 and the bottom plate 11, and one end of the guide plate 51 close to the second plate 122 is tilted upward, and the guide plate 51 extends to one end of the bottom plate 11 close to the second end 1114 in the lateral direction. The second guide member 6 is provided on the bottom plate 11. The second guide member 6 is provided with a guide block 61. The guide block 61 is located at the second side 1112 and outside the second plate 122. A gap is provided between the guide block 61 and the bottom plate 11. The end of the guide block 61 close to the second plate 122 is inclined for easy introduction of the book. The gap between the guide block 61 and the second plate 122 is larger than the gap between the guide plate 51 and the second plate 122. The guide block 61 extends to the end of the bottom plate 11 close to the second end 1114 in the lateral direction. In the above structure, the thicker half of the passport book passes under the bearing 31 and enters under the guide plate 51, and its lateral edge is limited by the guide plate 51; the tilted half of the passport book passes under the book pressing guide wheel 41 and enters under the guide block 61, and its lateral edge is limited by the guide block 61, so that the passport book is better in a flattened state, which is convenient for the connected printing device to receive the passport book. The gap between the guide plate 51 and the second plate 122 is small, so that the thicker half of the passport book can immediately enter under the guide plate 51 after passing under the bearing 31, so as to avoid the thicker half of the passport book from tilting and being unable to enter under the guide plate 51. The gap between the guide block 61 and the second plate 122 is large, and there can be space in the middle for the kinetic energy pressure mechanism 4. The guide plate 51 extends to the end of the bottom plate 11 that is close to the second end 1114 in the horizontal direction, and the guide block 61 extends to the end of the bottom plate 11 that is close to the second end 1114 in the horizontal direction, so that the passport book is always in a flat state when leaving the bottom plate 11. The end of the guide plate 51 close to the second plate 122 tilts upward, which is convenient for introducing the thicker half of the passport book. The end of the guide block 61 close to the second plate 122 is inclined, which is convenient for introducing the tilted half of the passport book. The second guide member 6 is made of POM material, which can not only ensure the smooth guidance and silky entry of the passport book, but also protect the important pages of the passport book from damage.
