Description

Technical Field

[0001] The utility model belongs to the field of printing, and particularly relates to a reeling and unreeling mechanism. Background Art

[0002] In the field of printing, the existing winding structure and unwinding structure are respectively located on both sides of the frame to respectively unwind and wind up; however, when replacing the printing material, the worker has to disassemble and install the printing material wound by the winding structure and the unwinding material on the unwinding structure at both sides of the frame, which is relatively troublesome and has low replacement efficiency;

[0003] For example, a 3D round hot stamping device disclosed in a prior patent (application number CN201720244762.5) includes a first frame, a second frame, a third frame, and a fourth frame connected in sequence, an unwinding unit arranged on the first frame, a printing unit arranged on the second frame, a round hot stamping unit arranged on the third frame, and a rewinding unit arranged on the fourth frame, and the round hot stamping unit includes a first unwinder arranged on one side of the upper end of the round hot stamping unit, a first rewinder arranged on the other side of the upper end of the round hot stamping unit, and a round hot stamping structure arranged below the midpoint of the center connection line between the first unwinder and the first rewinder. This device has the above-mentioned defects of the prior art. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A winding and unwinding mechanism, characterized in that the mechanism comprises:

[0007] An unwinding component for unwinding printing materials;

[0008] A winding assembly for winding up the printing material;

[0009] A guide component for guiding the path of the printing material;

[0010] A frame, wherein a first area and a second area for installing an external processing structure are respectively arranged on both sides of the frame, the guide component, the unwinding component and the rewinding component are all arranged on the frame, and the unwinding component and the rewinding component are both located in the first area; from the unwinding component through the guide component to the second area, and then from the second area through the guide component to the rewinding component, a printing material path for passing the supporting material is formed.

[0011] In the rewinding and unwinding mechanism, the unwinding assembly and the rewinding assembly are arranged in the same area on one side of the frame. When it is necessary to disassemble and assemble the printing material rewound by the rewinding assembly and the printing material unwound by the unwinding assembly, the worker can complete the work at the same position, and the disassembly and assembly process is more convenient, faster and more efficient. In addition, since the unwinding assembly and the rewinding assembly are both located on one side of the frame, it is more convenient to expand and install the corresponding structure on the other side of the frame as needed.

[0012] Furthermore, the reeling assembly and the unreeling assembly are arranged side by side.

[0013] Furthermore, the winding assembly includes a first winding roller and a second winding roller, the unwinding assembly includes an unwinding roller, and the first winding roller and the second winding roller are respectively arranged on both sides of the unwinding roller; the printing material path includes a first printing material path and a second printing material path; the first printing material path passes from the unwinding roller through the guide assembly to the second area, and then passes from the second area through the guide assembly to the first winding roller; the second printing material path passes from the unwinding roller through the guide assembly to the second area, and then passes from the second area through the guide assembly to the second winding roller. The first winding roller and the second winding roller can be arranged so that different winding rollers can be selected for winding as needed.

[0014] Furthermore, the second winding roller is located on the side of the unwinding roller close to the second area, and the first winding roller is located on the other side of the unwinding roller away from the second area. The position of the first winding roller allows it to wind up more printing materials, and the position of the second winding roller allows it to wind up relatively less printing materials. Different winding rollers can be selected for winding according to needs.

[0015] Further, the first area and the second area are respectively located on the left and right sides of the frame; the guide assembly includes a first guide roller group, a second guide roller group, and a third guide roller group, the first guide roller group is located on the upper side of the unwinding roller, the second guide roller group is located on the left and lower side of the first winding roller, the third guide roller group is located in the second area, and the first guide roller group, the second guide roller group, and the second winding roller all correspond to the third guide roller group;

[0016] The first printing material path is from the unwinding roller through the first guide roller group and the third guide roller group to the second area, and then from the third guide roller group through the second guide roller group to the first winding roller; the second printing material path is from the unwinding roller through the first guide roller group and the third guide roller group to the second area, and then from the third guide roller group to the second winding roller.

[0017] The beneficial effect of the utility model is that the unwinding assembly and the rewinding assembly are arranged in the same area on one side of the frame. When it is necessary to disassemble and assemble the printing material rolled up by the rewinding assembly and the printing material unrolled on the unwinding assembly, the workers can complete the work at the same position, and the disassembly and assembly process is more convenient, quick and efficient.
