[0003] When disassembling and installing the winding roller used for winding, the existing printing press paper delivery device needs to first unlock and move the clamping structures on both sides so that the distance between them is greater than the length of the winding roller to facilitate the disassembly and assembly of the winding roller, and then install the new winding roller, and then move the clamping structures on both sides again to make them clamp the winding roller, and then lock it to complete the replacement process of the winding roller and the paper roll thereon. This operation process has many steps, is cumbersome to use, and takes a long time to replace, which increases the time in the process of winding multiple paper rolls, and the use speed and efficiency are relatively low.

The same connecting shaft 6 is rotatably connected to the upper part between the two ground frames 1. The two ends of the connecting shaft 6 are respectively provided with the same connecting belt 7 on the outer side of one end of the adjacent main shaft 2. The connecting shaft 6 is used to drive the main shafts 2 on both sides to rotate through the connecting belt 7, which is convenient for being driven by a paper changing motor 8. A paper changing motor 8 is fixedly connected to one side of the left ground frame 1, and a pulley 9 is fixedly connected to the output end of the paper changing motor 8 and the outer left side of the connecting shaft 6. The outer sides of the two pulleys 9 The same belt 10 is tensioned respectively, and the installation position of the paper changing motor 8 can be adjusted conveniently by the cooperation of the pulley 9 and the belt 10; the paper collecting assembly includes a bidirectional screw rod 12 rotatably connected between the two vertical plates 11, a clamping motor 13 is fixedly connected to one side of the right ground frame 1, and the output end of the clamping motor 13 is fixedly connected to one end of the bidirectional screw rod 12, a sliding rod 14 is fixedly connected between the vertical plate 11 and the adjacent side of the ground frame 1, and a sliding rack 15 is arranged on the outer side of the sliding rod 14 on the same side, and a bending portion 16 is arranged on the sliding rack 15, and a pressing sleeve 17 is slidably connected in the bending portion 16, The pressing sleeve 17 is used to press one side of the pattern tube 3, and cooperates with the spring 19 and the flange 18 to adjust the distance between the bending part 16 and the pattern tube 3. The flange 18 is fixedly connected to the pressing sleeve 17, and a spring 19 is arranged between the flange 18 and the adjacent side of the bending part 16. The spring 19 is sleeved on the outer side of the pressing sleeve 17. A bracket 20 is fixedly connected to one side of the left bending part 16, and a paper collection motor 21 is fixedly connected to one side of the bracket 20. A fixed rod 22 is fixedly connected to the output end of the paper collection motor 21. The fixed rod 22 is used to contact and squeeze one side of the connecting end ring 26 to drive it to rotate slowly through friction.

[0030] A ring plate 23 is fixedly connected to the inner side of the left pressing sleeve 17, and a fixing rod 22 is rotatably connected to the inner side of the ring plate 23. There are arc grooves 24 distributed in a circular shape on the ring plate 23. The ring plate 23 is used to support the fixing rod 22. The arc grooves 24 can reduce material consumption and reduce manufacturing costs.

[0031] A convex ring 25 is rotatably connected inside the right pressing sleeve 17 , and the convex ring 25 is used to cooperate with the connecting end ring 26 on the other side to follow the movement, so as to facilitate the rotation of the winding roller 27 .

[0032] A connecting end ring 26 is provided in the accommodating groove 4, and the same winding roller 27 is provided between two coaxial connecting end rings 26. The two connecting end rings 26 are respectively inserted at the two ends of the winding roller 27 to facilitate its insertion into the accommodating groove 4.

[0033] A sliding hole and a threaded hole are respectively provided on the upper and lower sides of one side of the slide 15. The slide rod 14 is slidably connected to the inner side of the sliding hole. The threaded hole is threadedly connected to the bidirectional screw rod 12. The slide 15 limits its rotation through the cooperation of the sliding hole and the slide rod 14. The threaded connection with the bidirectional screw rod 12 is convenient for left and right movement driven by a motor, so as to facilitate the fixing and unlocking of the roller 27.

[0034] The left and right sides of the outer side of the bidirectional screw rod 12 are respectively provided with threads with opposite rotation directions. By providing threads with different rotation directions, a clamping motor 13 can drive the slides 15 on both sides to move relative to each other, thereby facilitating the fixing and unlocking of the winding roller 27, and the structure is simple.

[0035] The flower-shaped tube 3 is a hollow structure, and the flower-shaped tube 3 is made of plastic material. The hollow structure can reduce the amount of materials used and reduce the production cost.

[0036] When the present invention is used, the connecting end rings 26 are first inserted into the two ends of the winding roller 27, and the winding roller 27 with the connecting end rings 26 is inserted into the receiving groove 4. When entering the receiving groove 4, it is squeezed by the silicone strip 5. During the squeezing process, the silicone strip 5 is deformed and allows the connecting end ring 26 to pass through. After the connecting end ring 26 has completely passed through, the silicone strip 5 is restored to limit the rolling direction of one side of the connecting end ring 26. Then the above actions are repeated until the winding rollers 27 are inserted into the receiving groove 4. After that, the conventional operation will be installed. The paper surface is adhered and connected to the outer side of the top winding roller 27, and then the device is connected to an external power supply. The controller controls the clamping motor 13 and the paper collecting motor 21 to work in sequence. The clamping motor 13 drives the bidirectional screw rod 12 to rotate, and the threaded cooperation between the clamping motor 13 and the slide 15 drives the slides 15 on both sides to slide on the outer side of the slide rod 14, and drives the pressing sleeve 17 to move through the bending portion 16 until one side of the flange edge 18 on the pressing sleeve 17 contacts and squeezes one side of the adjacent pattern tube 3, so that the pressing sleeve 17 slides in the bending portion 16 and compresses the pressing sleeve 17 at the same time. The spring 19 is used until the convex ring 25 and one end of the fixing rod 22 on both sides respectively contact one end of the adjacent connecting end ring 26, and then the paper collection motor 21 drives the fixing rod 22 to rotate, and the static friction between it and the adjacent connecting end ring 26 drives the connecting end ring 26 and the winding roller 27 to rotate and roll the paper. At the same time, the connecting end ring 26 on the other side drives the convex ring 25 to rotate with the winding roller 27. After the paper is rolled, the controller controls the output end of the clamping motor 13 to rotate in the opposite direction, so that the convex ring 25 and the fixing rod 22 no longer contact the connecting end ring 26. Then, the paper changing motor 8 is controlled by the controller to work, and the connecting shaft 6 is driven to rotate through the cooperation of the pulley 9 and the belt 10. The two connecting belts 7 are used to drive the main shafts 2 on both sides to rotate a certain angle, so that the pattern tube 3 is rotated until the reel 27 in the other receiving groove 4 appears on the top, and then the above operation is repeated to continue the paper collection operation. During the paper collection process, the user can remove the rolled paper roll and reel 27, and only needs to make the connecting end ring 26 squeeze the silicone strip 5 again to pass through, and then the new reel 27 can be reinserted into the empty receiving groove 4.
