[0026] Specific examples are given below.

[0027] See also Figure 1 - Figure 6The utility model provides a winding device for packaging bag printing, comprising a workbench 1, a plurality of positioning frames 2 are fixedly installed at both ends of the top of the workbench 1, and a positioning roller 5 is rotatably connected to the middle of two positioning frames 2 at one end. A movable roller 3 is arranged on the top of the positioning roller 5, and rectangular blocks 202 are rotatably connected to both ends of the movable roller 3, and the outer wall of each rectangular block 202 is slidably connected to the inner wall of the positioning frame 2.

A plurality of drive motors 9 are arranged on one side of the workbench 1, one side of a drive motor 9 is fixedly connected to the movable frame 8, and the output shaft of a drive motor 9 is fixedly connected to one end of the insertion rod 10 via the movable frame 8. Two slide slots 13 are provided at one end of the workbench 1, and the middle parts of the two slide slots 13 are rotatably connected with a bidirectional threaded rod 15, and one end of the bidirectional threaded rod 15 is also fixedly connected to the drive motor 9. The outer walls of both ends of the bidirectional threaded rod 15 are threadedly connected to the bottom inner wall of the movable frame 8, and the two movable frames 8 slide inside the slide slots 13 via the bidirectional threaded rod 15.

[0028] During operation, by moving the workbench 1 to the rear of the printing press, the movable roller 3 can slide inside the positioning frame 2 by using the rectangular block 202, so that the printed packaging bag 4 can pass between the movable roller 3 and the positioning roller 5, and then fit on the top of the guide roller 6. After the winding roller 7 is moved between the two movable frames 8, a driving motor 9 is controlled to start, and the driving motor 9 drives the bidirectional threaded rod 15 to rotate, thereby driving the movable frame 8 to slide inside the slide groove 13. And as the movable frame 8 moves, the insertion rod 10 is inserted into the two ends of the winding roller 7, and then the packaging bag 4 is fixed to the outside of the winding roller 7 by means of adhesive tape or the like. When the packaging bag 4 needs to be wound up, the driving motor 9 on one side of the movable frame 8 is started, and the insertion rod 10 is driven to rotate by the output shaft of the driving motor 9, and the winding roller 7 is synchronously rotated by the engagement of one end of the insertion rod 10 with the inner wall of the winding roller 7, so that the packaging bag 4 is wound up. The packaging bag 4 can be smoothed by rotating the movable roller 3 and the positioning roller 5, and the guiding work of the packaging bag 4 can be completed by the guide roller 6, so as to prevent the packaging bag 4 from wrinkling or bending during the rolling process, thereby improving the rolling effect of the packaging bag 4. With the above method, after the rolling is completed, the winding roller can be quickly disassembled, which will reduce the consumption of a lot of time and energy during the operation and reduce the rolling efficiency of the packaging bag.

[0029] Further, such as Figure 2 and Figure 3As shown, one end of the movable roller 3 and the positioning roller 5 are fixedly connected to the driving motor 9, and one side of one driving motor 9 is fixedly connected to the positioning frame 2. One side of the other driving motor 9 is fixedly connected to one side of the rectangular block 202, and the movable roller 3 and the positioning roller 5 are rotated between the two positioning frames 2 through the driving motor 9. The outer side of each rectangular block 202 is sleeved with an open groove 201, and each open groove 201 is opened inside the positioning frame 2. One end of the open groove 201 is fixedly connected to a telescopic rod 203, and one end of each telescopic rod 203 is fixedly connected to the rectangular block 202, and each rectangular block 202 slides inside the open groove 201 through the telescopic rod 203. The outer side of each telescopic rod 203 is sleeved with a first spring 204, and one end of each first spring 204 is fixedly connected to the rectangular block 202.

[0030] During operation, the contraction of the telescopic rod 203 can drive the rectangular block 202 to slide inside the opening slot 201, so that the movable roller 3 is away from the side of the positioning roller 5, and the packaging bag 4 can be easily passed between the movable roller 3 and the positioning roller 5, and then the telescopic rod 203 is used to push the rectangular block 202 to fall, so that the bottom of the movable roller 3 is attached to the surface of the packaging bag 4, and the packaging bag 4 can be clamped. When it is necessary to roll up the packaging bag 4, the two driving motors 9 on one side of the positioning frame 2 are started at the same time, and the output shaft of the driving motor 9 is used to drive the movable roller 3 and the positioning roller 5 to rotate at the same time, so that the packaging bag 4 can be pressed and smoothed, and the packaging bag 4 can be assisted to complete the rolling up. When the packaging bag 4 is bent or the thickness is different, the first spring 204 is used to make the rectangular block 202 move slightly inside the opening slot 201, so that the packaging bag 4 can stably pass through the movable roller 3 and the positioning roller 5, and reduce the situation where the packaging bag 4 is jammed during rolling up and causes it to break.

[0031] Further, such as Figure 5 and Figure 6 As shown, two slide bars 14 are fixedly connected inside each slide groove 13, and the outer wall of each slide bar 14 is slidably connected to the inner wall of the movable frame 8. A rectangular groove 17 is provided inside a movable frame 8, and a connecting rod 11 is slidably connected inside the rectangular groove 17. A pressure rod 12 is rotatably connected to the top of the connecting rod 11, and one side of the pressure rod 12 is in contact with one side of the winding roller 7. A tooth groove 16 is provided on one side of the connecting rod 11, and a rack 18 is snap-connected to one side of the tooth groove 16. A connecting plate 19 is fixedly connected to one side of the rack 18, and the connecting plate 19 is slidably connected to the inner wall of one end of the movable frame 8. The rack 18 is slidably connected to the inner wall of the movable frame 8 via the connecting plate 19. A plurality of second springs 20 are fixedly connected to one side of the connecting plate 19, and the plurality of second springs 20 are arranged in an array. One end of each second spring 20 is fixedly connected to the inner wall of the movable frame 8 , a pull rod 21 is fixedly connected to the middle of the connecting plate 19 , and the middle of the pull rod 21 is slidably connected to the inner wall of the movable frame 8 .

[0032] During operation, when the movable frame 8 is driven to slide inside the slide groove 13 by the bidirectional threaded rod 15, the slide rod 14 can be used to prevent the movable frame 8 from being dislocated during the movement, thereby improving the stability of the structure. The connecting rod 11 is used to ensure the stability of the pressure rod 12, so that the pressure rod 12 fits the winding roller 7. The gravity of the pressure rod 12 can be used to press the packaging bag 4, thereby improving the tightness of the winding of the packaging bag 4 and preventing the packaging bag 4 from being loose after winding. And as the number of winding layers of the packaging bag 4 increases, the pressure rod 12 will drive the connecting rod 11 to slide inside the rectangular groove 17 to prevent the pressure rod 12 from being separated. And as the connecting rod 11 slides, the tooth groove 16 can be driven to slide outside the rack 18. The engagement of the rack 18 with the tooth groove 16 can prevent the connecting rod 11 from suddenly sliding off, and prevent the pressure rod 12 from suddenly falling off and injuring the staff when the winding roller 7 is removed, thereby improving the safety of the equipment. The connecting plate 19 can be used to prevent the rack 18 from falling off, thereby improving the stability of the structure. The connecting plate 19 can slide inside the movable frame 8 by using multiple second springs 20 fixed on one side of the connecting plate 19, thereby preventing the connecting rod 11 from getting stuck when moving, thereby improving the rewinding effect of the packaging bag 4. After replacing the rewinding roller 7, first fix one end of the packaging bag 4 to the outside of the rewinding roller 7, and then support the middle of the pressure rod 12. Then pull the pull rod 21, and use the pull rod 21 to pull the connecting plate 19 to move inside the movable frame 8, so that the connecting rod 11 slides inside the rectangular groove 17, so that the pressure rod 12 can be re-attached to the outside of the rewinding roller 7.

[0033] Working principle: By moving the workbench 1 to the rear of the printing press, the contraction of the telescopic rod 203 can drive the rectangular block 202 to slide inside the opening groove 201, so that the movable roller 3 is away from the side of the positioning roller 5, and the packaging bag 4 can be easily passed between the movable roller 3 and the positioning roller 5. Then the telescopic rod 203 is used to push the rectangular block 202 to fall, so that the bottom of the movable roller 3 is attached to the surface of the packaging bag 4. Then the packaging bag 4 is attached to the top of the guide roller 6, and then the packaging bag 4 is fixed to the outside of the winding roller 7 by means of adhesive tape or the like. When the packaging bag 4 needs to be wound up, the packaging bag 4 can be pressed by the gravity of the pressure rod 12. Then start the driving motor 9 on one side of the movable frame 8, use the output shaft of the driving motor 9 to drive the insertion rod 10 to rotate, and use the engagement of one end of the insertion rod 10 with the inner wall of the winding roller 7 to make the winding roller 7 rotate synchronously. The output shaft of the driving motor 9 is used to simultaneously drive the movable roller 3 and the positioning roller 5 to rotate, so that the packaging bag 4 can be pressed and smoothed, and then the guiding roller 6 is used to guide the packaging bag 4. As the number of layers of the packaging bag 4 increases, the pressure rod 12 will drive the connecting rod 11 to slide inside the rectangular groove 17, and can drive the tooth groove 16 to slide outside the rack 18. The engagement between the rack 18 and the tooth groove 16 can prevent the connecting rod 11 from suddenly sliding off, and complete the winding of the packaging bag 4. When the winding roller 7 needs to be replaced, first support one end of the pressure rod 12 to keep it away from the winding roller 7, then use a blade to cut the packaging bag 4 wound on the outside of the winding roller 7, and then use an auxiliary device to support the two ends of the winding roller 7. Then, the driving motor 9 is used to drive the bidirectional threaded rod 15 to rotate, so that the two movable frames 8 drive the insertion rod 10 to separate from the two ends of the winding roller 7, and the winding roller 7 can be removed. Then, a new winding roller 7 is placed between the two movable frames 8 , and the insertion rod 10 is inserted into both ends of the winding roller 7 , so that the replacement of the winding roller 7 is completed.
