Description

Technical Field

[0001] The utility model relates to a step-by-step approach roller winding device, belonging to the field of printing machinery. Background Art

[0002] When the printing press is rewinding, there is no printing material on the rewinding shaft at the beginning. The diameter of the rewinding shaft is small and it is far away from the wall panel of the printing press. The printed material is prone to wrinkles during the long transmission distance, resulting in waste. The rewinder and the printing press are both unable to move. If the distance between the rewinding shaft and the wall panel is close at the beginning, the final diameter of the rewind will be greatly restricted, which will reduce the rewinding efficiency. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides a step-by-step approach roller winding device, which can make the approach rollers move synchronously and reduce the generation of wrinkles.

[0004] To achieve this purpose, the structure adopted by the present invention is: a step-by-step approach roller winding device, including a fuselage wall panel and a winder, the winder is arranged next to the fuselage wall panel, and a step-by-step approach roller and a material receiving and cutting knife group are arranged on the side of the fuselage wall panel close to the winder, the step-by-step approach roller includes an approach roller and a step-by-step connecting structure, and the approach roller is connected to the fuselage wall panel through the step-by-step connecting structure.

[0005] The step-by-step connection structure includes a transmission shaft and a support plate. Two support plates are symmetrically arranged at both ends of the approach roller, and the support plates are connected to the fuselage wall panel. Slide rails and racks are arranged on the support plates. A fixed plate is connected to each end of the approach roller, and a transmission shaft is connected between the two fixed plates. Gears are arranged at both ends of the transmission shaft and mesh with the racks at both ends. The fixed plate is connected to the slide rail through a slider, and a synchronous motor is connected to the fixed plate. The synchronous motor is connected to the transmission shaft through a belt.

[0006] A static elimination plate is provided beside the approach roller, and both ends of the static elimination plate are connected to the roller shaft of the approach roller.

[0007] The two ends of the approach roller are connected to the fixed plate through the guide roller adjustment block.

[0008] The beneficial effects are: the structural design of the utility model is reasonable and ingenious, and the step-by-step connection structure enables the approach roller to move synchronously with the gradual increase in the diameter of the receiving reel on the winder, so that the approach roller and the reel maintain a certain distance, avoiding the distance being too large and causing wrinkles in the printed material during the reeling process.

[0016] like Figure 1 The step-by-step approach roller winding device shown includes a fuselage wall panel 1 and a winder 4. The winder 4 is arranged beside the fuselage wall panel 1. Figure 2 As shown, a step-by-step approach roller 2 and a receiving and cutting knife group 3 are provided on the side of the fuselage wall panel 1 close to the winder 4. The step-by-step approach roller 2 is arranged above the receiving and cutting knife group 3. The step-by-step approach roller 2 includes an approach roller 22 and a step-by-step connecting structure. The approach roller 22 is connected to the fuselage wall panel 1 through the step-by-step connecting structure.

[0017] like Figure 3As shown, the step-by-step connection structure includes a transmission shaft 27 and a support plate 21. Two support plates 21 are symmetrically arranged at each end of the approach roller 22. The support plates 21 are connected to the fuselage wall panel 1 and are equipped with reinforcement plates to increase the load-bearing capacity of the support plates 21. A slide rail 23 and a rack 24 are provided on the support plate 21. The slide rail 23 and rack 24 are parallel to each other. A fixed plate 26 is connected to each end of the approach roller 22. A transmission shaft 27 is connected between the two fixed plates 26. Gears are provided at each end of the transmission shaft 27 and mesh with the racks 24 at each end. The fixed plate 26 is connected to the slide rail 23 via a slider. A synchronous motor 25 is connected to the fixed plate 26, and the synchronous motor 25 is connected to the transmission shaft 27 via a belt. The synchronous motor 25 drives the rotation of the transmission shaft 27. Driven by the gear and rack 24, the fixed plate drives the approach roller 22 to move back and forth along the slide rail 23, achieving synchronous movement of the approach roller 22 and the winder 4.

[0018] A static eliminator 29 is provided next to the approach roller 22, and both ends of the static eliminator 29 are connected to the roller shaft of the approach roller 22. The static eliminator 29 is a conductive plate that can eliminate static electricity on the printed material and reduce wrinkles caused by static electricity.

[0019] The two ends of the approach roller 22 are connected to the fixed plate 26 via a guide roller adjustment block 28. The guide roller adjustment block 28 is provided with a long strip groove, and the two ends of the approach roller 22 are connected in the groove. By adjusting the height position of the approach roller 22 in the groove, the height of the approach roller 22 can be adjusted.

[0020] The receiving and cutting knife group 3 is provided with a swing arm and a cutter. The cutter is connected to the swing arm. The swing arm is connected to the fuselage wall panel 1 through a rotating shaft and is driven by a cylinder to swing to achieve cutting of the printed material.

[0021] The structural design of the utility model is reasonable and ingenious. The step-by-step connection structure enables the approach roller to move synchronously with the gradual increase of the diameter of the receiving reel on the winder, so that the approach roller and the reel maintain a certain distance, avoiding the generation of wrinkles in the printed material during the reeling process due to excessive distance.
