[0095] When working, the fruit bag 15 is put on the paper roll 16, and the gear box 7 in the fruit bag transmission mechanism 3 starts to work. The driving mechanism 8 drives the paper pressing wheel 6 above the paper roll 16 to rotate, and drives the fruit bag 15 to move forward. When the fruit bag 15 reaches the bag-supporting mechanism 4, the fruit bag 15 passes between the paper pressing wheel 6 and the paper rolling wheel 17 and reaches the entrance of the fruit bag-supporting plate 18. Since the fruit bag-supporting plate 18 is a wide-in and narrow-out structure, it has a gradual process of decreasing width and increasing height, so that the fruit bag 15 is squeezed by the decreasing width, thereby realizing the fruit bag 15 to be opened. The fruit bag 15 is transferred to the nailing and bag sealing mechanism 5 through the chrome-plated optical axis support 10, the linear bearing 11 and the slider mounting plate 41. The driving mechanism 8 can be preferably a DC motor. The motor drives the main gear 19 and the paper feeding driving wheel 20 to move. The paper feeding driving wheel 20 moves the paper feeding intermediate wheel 22 and the paper feeding intermittent wheel 21, so that the paper pressing wheel 6 produces intermittent rotation. Each intermittent process conveys a fruit bag 15 of a predetermined required length. When the fruit bag 15 reaches the upper dead point, the conveying of the fruit bag 15 is stopped. After the bagging is completed, the bag is sealed by the nail box connector 9, the nailing mechanism 13 and the staple box 14. When the fruit bag 15 reaches the nailing mechanism 13, after the bagging is completed, the blade connector 29 starts to work, and the upper and lower cutters 31 and 40 cut off the end of the fruit bag 15. The front end of the fruit bag 15 is nailed and sealed by the nail box connector 9, the nailing mechanism 13 and the slider connecting plate 12. The main gear 19 in the gear box 7 drives the crank shaft gear 24, crank shaft 25, crank 26 and cam 27 to rotate under the drive of the motor. The movement of the cam 27 drives the template hinge plate 28, the blade connector 29, the nail mold mounting plate 30, and the lower cutter 40 to swing upward and reach the top dead center; at the same time, the crank 26 pushes the slider connecting plate 12 to move through the connecting rod 32, drives the pressure nail bearing seat 34 to move forward, applies pressure to the pressure nail inclined block 35, so that the pressure nail plate 36 presses the nail downward, completing the process of pressing the nail to seal the bag and cutting the bag.

[0096] After the bag is sealed, the template hinge plate 28, the blade connector 29, the nail mold mounting plate 30, and the lower cutter 40 swing downward under the combined action of the cam 27 and gravity to reach the lower dead point; the crank 26 drives the slider connecting plate 12 and the pressure nail bearing seat 34 to move backward through the connecting rod 32, and the compression spring rebounds to drive the pressure nail inclined block 35 and the pressure nail plate 36 to move upward, and the entire bagging action is completed, and the second fruit bag 15 starts to move forward and enters the next cycle.

[0097] The present invention can control the operation of the fruit bag feeding mechanism 2, the fruit bag transmission mechanism 3, the bag support mechanism 4 and the bag sealing mechanism 5 through the DC motor control system of the driving mechanism 8. As the motor rotates, the main gear 19 in the gear box 7 drives the crankshaft gear 24, the crankshaft 25, the crank 26 and the cam 27 to rotate under the drive of the motor. The movement of the cam 27 drives the template hinge plate 28, the blade connector 29, the nail mold mounting plate 30, and the lower cutter 40 to swing upward to reach the top dead center. At the same time, the crank 26 pushes the slider connecting plate 12 to move through the connecting rod 32, drives the pressure nail bearing seat 34 to move forward, and applies pressure to the pressure nail inclined block 35, so that the pressure nail plate 36 presses the nail downward, completing the process of pressing the nail, sealing the bag and cutting the bag.

[0098] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
