DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides an embodiment: a printing press material winding device, including a winding base 1, a rotating bracket 2, a support plate 3, a winding drum 4, an expansion and contraction drum 5, a magnetic powder clutch 6 and a servo motor 7. The winding base 1 is symmetrically fixed with two first slide bars 9, and the end of the first slide bar 9 away from the winding base 1 is fixedly installed on the support plate 3. The first slide bar 9 is slidably connected with a discharge plate 10. The support plate 3 is fixedly installed on the winding base 1. A first multi-section electric A movable push rod 13 is provided, and two second slide rods 12 are symmetrically fixedly installed on one side of the support plate 3 close to the first multi-section electric push rod 13. The second slide rod 12 is slidably connected to the support rod 11. The input end of the magnetic powder clutch 6 is fixedly installed with a first transmission wheel 14, and the driving end of the servo motor 7 is fixedly installed with a second transmission wheel 15. A second multi-section electric push rod 16 is fixedly installed on the winding base 1. One end of the expansion and contraction reel 5 is fixedly installed on the driving end of the magnetic powder clutch 6, and the end of the expansion and contraction reel 5 away from the magnetic powder clutch 6 is rotatably connected to the groove shaft 8.

[0022] A rotating frame 17 is rotatably connected to the rotating bracket 2, and a plurality of groove transfer rollers 18 are rotatably connected to the inner side of the rotating frame 17. The rotating bracket 2 is arranged on the side of the support plate 3 away from the winding base 1, and the top height of the groove transfer roller 18 is lower than the height of the first slide bar 9. One end of the rotating frame 17 is fixedly connected to a baffle 20, and two handles 19 are symmetrically fixedly connected to the outer side of the end of the rotating frame 17 away from the baffle 20. A rubber blocking plate 21 is fixedly installed on the rotating bracket 2, and a support cross bar 22 is fixedly connected to the top of the end of the rotating bracket 2 close to the handle 19.

[0023] The magnetic powder clutch 6, the servo motor 7 and the second multi-section electric push rod 16 are all fixedly mounted on the winding base 1, and the servo motor 7 is located between the magnetic powder clutch 6 and the second multi-section electric push rod 16. The telescopic end of the second multi-section electric push rod 16 is fixedly connected to the unloading plate 10. The first transmission wheel 14 and the second transmission wheel 15 are connected through a conveyor belt transmission. The magnetic powder clutch 6 can automatically adjust the winding speed according to the tension of the printing material, so that the winding speed is uniform.

[0024] The telescopic end of the first multi-section electric push rod 13 is fixedly connected to the middle part of the bottom end of the support rod 11, and the inner side of the top end of the support rod 11 is close to the outer side of the bottom end of the groove shaft 8. The telescopic movement of the first multi-section electric push rod 13 drives the support rod 11 to slide on the second slide rod 12, so that the support rod 11 can support the groove shaft 8 when the winding drum 4 is wound, and when the winding is completed, the support rod 11 slides to the bottom to avoid blocking the disassembly of the printing material.

[0025] The middle part of the rotating frame 17 is rotatably connected to the rotating bracket 2 at the outer side near the baffle 20, and the top of the supporting cross bar 22 is close to the bottom end of the rotating frame 17 in the horizontal state. Since the connection between the rotating frame 17 and the winding base 1 is located at the center position close to the side of the baffle 20, the rotating frame 17 is in a horizontal position under normal conditions, and the side of the rubber blocking plate 21 away from the supporting cross bar 22 is close to the bottom end of the rotating frame 17 in the vertical state. When the rotating frame 17 is rotated to the vertical state by external force, the rubber blocking plate 21 can prevent the rotating frame 17 from rotating more than ninety degrees and throwing out the printed material.

[0026] A notch is provided in the middle of the baffle 20, through which a hand-pushed forklift can be used to transfer the printing materials.

[0027] Working principle: During use, the winding drum 4 is first nested on the outside of the expansion and contraction drum 5 by external force, and then the expansion and contraction drum 5 is controlled to expand to fix the winding drum 4 on the outside of the expansion and contraction drum 5, and then the first multi-section electric push rod 13 is controlled to extend, and the telescopic end of the first multi-section electric push rod 13 pushes the support rod 11 to slide upward on the second slide rod 12 until the inner side of the top end of the support rod 11 is close to the bottom end of the groove shaft 8, and then the printing material is wound on the outside of the winding drum 4 and the servo motor 7 is started. The driving end of the servo motor 7 drives the second transmission wheel 15 to rotate, and the rotation of the second transmission wheel 15 drives the first transmission wheel 14 to rotate through the conveyor belt, and the rotation of the first transmission wheel 14 drives the magnetic powder clutch 6 to start, and the driving end of the magnetic powder clutch 6 drives the expansion and contraction drum 5 to rotate, and the expansion and contraction drum 5 drives the winding drum 4 to rotate to start winding the printing material. When the winding is completed, the printing material is divided, and then The expansion and contraction reel 5 is controlled to retract, and the first multi-section electric push rod 13 is controlled to retract at the same time. The telescopic end of the first multi-section electric push rod 13 drives the support rod 11 to move downward to the initial position, and then the second multi-section electric push rod 16 is controlled to extend. The telescopic end of the second multi-section electric push rod 16 pushes the unloading plate 10 to slide on the first slide bar 9 close to the support plate 3. The sliding of the unloading plate 10 pushes the printing material on the outside of the winding drum 4 close to the support plate 3. When the winding drum 4 and the wound printing material contact the groove transfer roller 18, the printing material rolls on the groove transfer roller 18 to the baffle 20. At this time, the winding drum 4 is completely separated from the expansion and contraction reel 5, and then the handle 19 is pushed upward by external force. The movement of the handle 19 drives the rotating frame 17 to rotate to a vertical position. At this time, the printing material wound on the winding drum 4 is placed vertically on the baffle 20, and then the printing material can be transferred to the storage area by a hand-pushed forklift.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
