[0002] Package printing is the printing with various packaging materials as carriers, and printing decorative patterns, patterns or texts on the packaging to make the product more attractive or more descriptive, so as to convey information and increase sales. It includes the printing of packaging cartons, packaging bottles, packaging cans, etc. Package printing occupies a large proportion in both the printing industry and the packaging industry, and is an indispensable part of packaging engineering. There are printing methods such as letterpress printing, flat printing, gravure printing, screen printing, and perforated plate printing. The main elements of printing are paper, ink, color, etc. Package printing needs to take into account issues such as economy and environmental protection, and at the same time, it needs to be able to fully and well express the information to be printed. In the current production process of packaging and decoration printed products, winding is an indispensable process. However, the existing winding devices are mostly wound with several reels, lack of protective structure for printed products, and are prone to loosening, which leads to uneven winding and unstable winding size, which not only affects the quality of printed products, but also increases production costs.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a winding device for producing packaging and decoration printed materials. Figure 1-Figure 3 , including a winding bracket 1, a turntable 9 is symmetrically provided on the inner wall at the top of the winding bracket 1, a winding drum 5 is installed between the two turntables 9, a winding chamber 10 is opened in the winding bracket 1, a bearing 7 is installed on the inner wall of one side of the winding chamber 10, the bearing 7 is rotatably connected with the winding drum 5, a servo motor is installed on the outer wall of one side of the winding bracket 1, the output end of the servo motor extends into the winding chamber 10 and is transmitted to one end of the winding drum 5, and can drive the winding drum 5 to rotate to wind up the printed matter. Since a card slot 12 is opened inside the winding drum 5, and the inner wall on one side of the card slot 12 is an integrated structure with a clamping edge 13, one end of the printed matter can be fixed in the card slot 12 in advance, so as to facilitate the winding of the printed matter.

[0020] like Figure 2 As shown, a group of positioning frames 6 are symmetrically arranged on the outer wall of the turntable 9, and two positioning frames 6 are arranged, which are respectively located at the top and the back wall of the turntable 9, and can limit the upper and back of the printed matter, and an inner slide 14 is opened inside the positioning frame 6, and a support spring 15 is fixedly connected to one end of the inner wall of the inner slide 14, and a connecting slide rod 16 is slidably arranged at the other end of the inner wall of the inner slide 14, and the support spring 15 can squeeze the connecting slide rod 16;

[0021] A compaction roller 8 is movably provided on the positioning frame 6, and the ends of the two connecting slide bars 16 that are close to each other are rotatably connected to the compaction roller 8, while the ends of the two connecting slide bars 16 that are away from each other extend to the outside of the inner slide 14 and are fixed with a limiting baffle 11. Therefore, the compaction roller 8 can be pushed close to the outside of the winding drum 5 to protect the upper part of the printed matter and improve the compactness of the winding.

[0022] In addition, a fixed plate 2 is symmetrically welded to the outer wall of the front end of the winding bracket 1, and a group of rotating shafts 3 are symmetrically arranged between the two fixed plates 2. An auxiliary rotating drum 4 is rotatably installed on the outer wall of the rotating shaft 3. One end of the printed product can be extended between the two auxiliary rotating drums 4 to the inside of the winding drum 5 for fixing. The two auxiliary rotating drums 4 can smooth the outside of the printed product, which has a good auxiliary winding effect.

[0023] The implementation principle of a winding device for producing packaging and decoration printed materials in the embodiment of the present application is as follows: when in use, one end of the packaging and decoration printed material to be wound is passed through the two auxiliary rotating drums 4 in advance and is passed through the gaps between the two compacting rollers 8 and the winding drum 5 in turn, and is extended into the clamping slot 12 and fixed on the clamping edge 13, and then the servo motor is started to drive the winding drum 5 to rotate on the winding bracket 1, and then the auxiliary rotating drum 4 cooperates to rotate on the rotating shaft 3 to smooth the surface of the printed material to avoid wrinkles. At the same time, due to the elasticity of the supporting spring 15, the compacting roller 8 will be driven to push the printed material close to the outer wall of the winding drum 5, which plays a role of tight compaction. As the winding thickness of the outer wall of the winding drum 5 gradually increases, the diameter expands at this time, and the compacting roller 8 drives the connecting slide rod 16 to cooperate upward in the inner slideway 14 with the elasticity of the supporting spring 15, so as to adapt to the appropriate compaction space, improve the winding effect, and ensure the compactness of the winding.
