[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a rapid paper feeding device for a rotary printing press, including a paper feeding frame 1;

[0022] Paper feeder 1: A rotating frame 2 is located on the right end of the internal structure. The left end of the rotating frame 2 is rotatably connected to symmetrically distributed paper roll rods 4. Both ends of the outer surface of the paper roll rods 4 are provided with external threads 5. A positioning disc 6 is threadedly connected to the middle of each external thread 5. The positioning disc 6 rotates under the action of the external threads 5, adjusting the distance between two horizontally adjacent positioning discs 6, thereby achieving stable positioning of paper rolls of different widths. A control switch group 17 is located in the middle of the left side surface of the paper feeder 1. The input end of the control switch group 17 is electrically connected to an external power source. A rotating mechanism 3 is provided between the rotating frame 2 and the paper feeder 1. The rotating mechanism 3 includes a rotating ring 31, a rotating shaft 32, and a drive handle 33. The rotating mechanism 3 is rotatably connected to the right end of the upper paper holder 1. The rib grooves inside the rotating ring 31 are slidably connected to the ribs of the corresponding rotating shaft 32. The left end of the rotating shaft 32 is fixedly connected to the right end of the rotating frame 2. The right end of the rotating shaft 32 is fixedly connected to the drive handle 33. The rotating mechanism 3 also includes a locking nut 34, a locking rod 35, and a positioning seat 36. The locking rod 35 is symmetrically fixedly connected to the upper and lower ends of the right side surface of the upper paper holder 1. The upper and lower ends of the drive handle 33 are provided with round holes. The middle part of the locking rod 35 is fixedly connected to the positioning seat 36. The right end of the outer surface of the positioning seat 36 is inserted into the horizontally adjacent round hole. The right end of the outer surface of the locking rod 35 is provided with external thread 2. The middle part of the external thread 2 is provided with external thread 2. A locking nut 34 is threadedly connected, with its left end face fitting against the right end face of the drive handle 33. Rotating the locking nut 34 causes it to separate from its corresponding locking rod 35. Then, the drive handle 33 pulls the rotating shaft 32 to the right, causing it to slide to the right inside the rotating ring 31. This movement of the rotating frame 2 to the right causes the two paper roll rods 4 to move to the right, ending the insertion of the lower paper roll rod 4 into the connecting cylinder 8. The drive handle 33 then rotates the rotating shaft 32, with the rotating ring 31 following and assisting in the rotation. The rotation of the rotating shaft 32 causes the rotating frame 2 to rotate 180 degrees, thus loading the paper rolls with complete paper rolls. The paper roll 4 rotates to the lower end, and then the drive handle 33 pushes the rotating shaft 32 to the left. The rotating shaft 32 moves to the left, causing the rotating frame 2 to move to the left, which in turn causes the paper roll 4 to move to the left, so that the ribs 7 are all inserted into the corresponding rib grooves inside the connecting cylinder 8, realizing the transmission connection between the lower paper roll 4 and the drive shaft 9. At the same time, the locking rods 35 all pass through the inner round holes of the drive handle 33, and the right end of the outer surface of the positioning seat 38 is inserted into the inner wall of the corresponding round hole. Then, the locking nut 34 is rotated back and connected to the right end of the locking rod 35. When the left side surface of the locking nut 34 is tightly attached to the right side surface of the drive handle 33, the rotation of the locking nut 34 is stopped, thereby locking the position of the rotating shaft 32.

[0023] The upper paper holder 1 has a drive shaft 9 rotatably connected to the lower end of its left side surface. A connecting cylinder 8 is fixedly connected to the right end of the drive shaft 9. The inner wall of the connecting cylinder 8 is provided with evenly distributed rib grooves. The left end of each paper roll rod 4 is fixedly connected with evenly distributed ribs 7, each rib 7 being inserted into a radially adjacent rib groove. A driven pulley 10 is fixedly connected to the left end of the drive shaft 9. A motor 12 is located at the rear end of the upper paper holder 1. A drive pulley 11 is fixedly connected to the left end of the output shaft of the motor 12. The driven pulley 10 and the drive pulley... 11 is connected by a transmission belt. The input end of motor 12 is electrically connected to the output end of control switch group 17. Motor 12 is operated by control switch group 17. The output shaft of motor 12 rotates, which drives drive pulley 11 to rotate. Drive pulley 11 rotates through the transmission belt driven pulley 10. Drive pulley 10 rotates, which drives drive shaft 9 to rotate. Drive shaft 9 rotates, which drives connecting cylinder 8 to rotate. Connecting cylinder 8 drives the horizontally adjacent paper roll rod 4 to rotate through rib 7. The rotation of paper roll rod 4 releases the paper.

[0024] The upper end of the upper paper holder 1 is rotatably connected to a fixed roller 16. The front end of the upper paper holder 1 is fixedly connected to two horizontal plates 15. Two vertically distributed conveyor rollers 13 are rotatably connected between the two horizontal plates 15. The left end of each conveyor roller 13 is fixedly connected to a gear, and the two gears mesh together. The front end of the right side surface of the upper paper holder 1 is equipped with a second motor 14. The left end of the output shaft of the second motor 14 is fixedly connected to the right end of the horizontally adjacent conveyor roller 13. The input end of the second motor 14 is electrically connected to the output end of the control switch group 17. The paper passes through the upper end of the fixed roller 16 and between the two conveyor rollers 13 in sequence. At the same time, the control switch group 17 realizes the operation of the second motor 14. The output shaft of the second motor 14 rotates, which drives the lower conveyor roller 13 to rotate. The rotation of the lower conveyor roller 13 drives the lower gear to rotate, which in turn drives the upper gear to rotate. The rotation of the upper gear drives the upper conveyor roller 13 to rotate. The two conveyor rollers 13 rotate in opposite directions, realizing the paper conveying and conveying the paper to the printing area of ​​the rotary printing press.

[0025] The working principle of the rapid paper feeding device for a rotary printing press provided by this utility model is as follows: During operation, the operator first places the paper feeder 1 and other mechanisms stably in the horizontal working area. After stable placement, the operator controls the switch group 17 to start the motor 12. The output shaft of the motor 12 rotates, driving the drive pulley 11 to rotate. The drive pulley 11 rotates through the transmission belt driven pulley 10. The driven pulley 10 rotates, driving the drive shaft 9 to rotate. The drive shaft 9 rotates, driving the connecting cylinder 8 to rotate. The connecting cylinder 8 rotates through the rib 7, driving the horizontally adjacent paper roll bar 4 to rotate. The rotation of the paper roll bar 4 releases the paper, which then passes through the fixed roller 1 in sequence. Between the upper end of 6 and the two conveyor rollers 13, the control switch group 17 simultaneously activates the second motor 14. The output shaft of the second motor 14 rotates, driving the lower conveyor roller 13 to rotate. The rotation of the lower conveyor roller 13 drives the lower gear to rotate, which in turn drives the upper gear to rotate. The rotation of the upper gear drives the upper conveyor roller 13 to rotate. The two conveyor rollers 13 rotate in opposite directions, thus conveying the paper to the printing area of ​​the rotary printing press. After the lower paper roll bar 4 has finished conveying, the operator turns off the first motor 12 by controlling the switch group 17. Then, the operator first rotates the locking nut 34 so that the locking nut 34 is engaged with the corresponding locking rod 35. After separation, the operator pulls the rotating shaft 32 to the right using the drive handle 33. The rotating shaft 32 slides to the right inside the rotating ring 31, thereby causing the rotating frame 2 to move to the right. The rightward movement of the rotating frame 2 causes the two paper roll rods 4 to move to the right, and the left end of the lower paper roll rod 4 is finally inserted into the connecting cylinder 8. Then, the operator rotates the rotating shaft 32 using the drive handle 33. The rotating ring 31 follows and assists the rotation of the rotating shaft 32. The rotation of the rotating shaft 32 causes the rotating frame 2 to rotate. The rotating frame 2 rotates 180 degrees, rotating the paper roll rod 4 with the complete paper roll to the lower end. Then, the operator pushes the rotating shaft 32 to the left using the drive handle 33. The rotating shaft 32 moves to the left, causing the rotating frame 2 to move to the left, thereby causing the paper roll rod 4 with the complete paper roll to move to the lower end. The paper roll rod 4 moves to the left, so that the ribs 7 are all inserted into the corresponding rib grooves inside the connecting cylinder 8, realizing the transmission connection between the lower paper roll rod 4 and the drive shaft 9. At the same time, the locking rods 35 all pass through the inner round holes of the drive handle 33, and the right end of the outer surface of the positioning seat 38 is inserted into the inner wall of the corresponding round hole. Then, the operator rotates the locking nut 34 back to the right end of the locking rod 35. When the left side surface of the locking nut 34 is tightly attached to the right side surface of the drive handle 33, the rotation of the locking nut 34 is stopped, thereby locking the position of the rotating shaft 32. Then, the operator controls the switch group 17 to start the motor 12 to continue the paper feeding.

[0026] It is worth noting that the control switch group 17 disclosed in the above embodiments is provided with control buttons that correspond one-to-one with motor 12 and motor 2 14 and control their switching.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
