Description

Technical Field

[0001] The utility model relates to the technical field of paper printing, in particular to a hot stamping device which is convenient for production conversion. Background Art

[0002] Depending on customer needs, paper materials have different processing flows during the printing process. For example, when printing cigarette packaging paper, sometimes the packaging paper needs to be hot stamped and embossed, and sometimes only hot stamping is required. In the existing technology, in order to facilitate product classification, hot stamping and embossing are generally carried out independently in two steps. Some products are processed directly in the hot stamping production line, while other products are first processed in the embossing production line and then transferred to the hot stamping production line. The above situation has a negative impact on printing efficiency and increases processing costs to a certain extent.

[0003] Some existing technical solutions integrate the hot stamping and embossing mechanisms so that the equipment can perform hot stamping and embossing on paper at one time. Although this solution solves the problem of paper transfer between the hot stamping and embossing processes, in actual production, the embossing process is generally targeted at some high-end products, which have a relatively small demand. In most cases, only the hot stamping function is used. At this time, the existence of the embossing mechanism affects the transfer of paper between the unwinding mechanism and the hot stamping mechanism, causing inconvenience in use. It is often necessary to equip a separate hot stamping device, which fails to achieve the purpose of flexible adjustment of the process. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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. Example

[0028] Reference Figure 1 The embodiment of the first aspect of the present utility model discloses a hot stamping device that is convenient for production conversion, which includes a feeding unit 1, an embossing unit 2, a hot stamping unit 3 and a positioning connector 4, specifically:

[0029] The feeding unit 1 includes a first base 11, a feeding mechanism 12, a first guide roller 13, a feeding arm 14 and a first driving cylinder 15. The downstream side of the first base is provided with a connection hole that can be matched with a screw. The feeding mechanism includes two parallel guide platforms 121, and a feeding channel is formed between the two guide platforms. The guide platform includes a horizontal guide surface 1211 and a positioning groove surface 1212. The first end of the feeding arm is movably hinged to the first base, and the second end of the feeding arm is provided with a feeding hook. The feeding arm is connected to the first driving cylinder. The first driving cylinder moves the loading arm within a 90° range between the horizontal and vertical states. When loading, the loading arm is first placed in a horizontal state, with the loading hook opening facing upward. The protruding shaft heads on both sides of the paper roll are placed into the loading hooks. The first driving cylinder rotates the loading arm to a vertical state. At this time, the loading hooks correspond to the positions of the horizontal guide surfaces, so that the shaft heads of the paper roll overlap the guide table and are transferred to the positioning groove surface via the horizontal guide surface. The loading of the paper roll is completed, and the paper is unwound to the downstream mechanism through the first lead-out roller.

[0030] The embossing unit 2 includes a second base 21, an embossing mechanism 22, a first introduction roller 23, a second export roller 24, a movable arm 25 and a second driving cylinder 26. The upstream and downstream sides of the second base are both provided with connection holes that can be matched with screws. The upper side of the second base is provided with a mounting base, and the lower side of the embossing mechanism is detachably connected to the mounting base. The embossing mechanism includes a mounting frame 221, an embossing steel roller 222 and a wool roller 223. The embossing steel roller and the wool roller are arranged to emboss paper materials. The first introduction roller is connected to the mounting frame and is arranged upstream of the embossing mechanism. The second export roller is The movable arm is connected to the first end and is arranged downstream of the embossing mechanism. The second end of the movable arm is movably hinged to the second base. The second driving cylinder is connected to the movable arm and allows the movable arm to rotate, thereby adjusting the height position of the second lead-out roller. The second end of the second lead-out roller is connected to the first gear 251. The second base is provided with a second gear 211 that meshes with the first gear. The second base is also provided with a plurality of positioning holes 212 distributed in an annular manner. The first gear is provided with matching holes 252 corresponding to the positioning holes. A fixing piece can be inserted through the positioning holes and the matching holes so that the movable arm maintains its own position state.

[0031] The hot stamping unit 3 includes a third base 31, a hot stamping mechanism 32 and a second introduction roller 33. The upstream side of the third base is provided with a connection hole, and the second introduction roller is provided on the upstream side of the hot stamping mechanism.

[0032] Both ends of the positioning connector 4 form connecting ends, and the connecting ends are provided with fixing holes corresponding to the connecting holes. The connecting ends can be detachably fixedly connected to the first base, the second base or the third base through connecting bolts.

[0033] Figure 2 A schematic diagram of the second working state of the printing device disclosed in the above embodiment is shown. In the second working state, the embossing mechanism is released from the second base, so that the obstruction between the feeding mechanism and the hot stamping mechanism is eliminated. At this time, the paper can be directly hot stamped. It should be noted that in order to ensure the smooth transportation of the paper, the height of the first lead-out roller and the second lead-in roller needs to exceed the mounting base of the second base to avoid contact between the paper and the second base. In addition, due to the large distance between the feeding mechanism and the hot stamping mechanism, the movable arm can be adjusted to make the second lead-out roller contact with the paper, provide tension to the paper, and avoid slack.

[0034] Figure 3 The third working state diagram of the printing device disclosed in the above embodiment is shown. In the third working state, the second base and the embossing mechanism are removed, and the first base and the third base are directly fixedly connected by a positioning connector. At this time, the paper can be directly hot stamped. Figure 1 and Figure 3 Adjust between the working states shown, refer to Figure 4 Movable wheels may be provided at the bottom of the first base and the second base, and the second base may be conveniently moved out and the first base may be moved to a position close to the third base by the movable wheels.

[0035] Reference Figure 5 In another embodiment, the embossing unit further includes a treadle platform 27, which is fixedly connected to the upstream side of the second base. A walkway 271 is formed in the middle of the treadle platform for paper to pass through. A first guide roller 272 and a second guide roller 273 are respectively provided at the upstream and downstream ends of the walkway. By standing on the treadle platform, workers can observe the embossing of the paper from a direction perpendicular to the paper surface, ensuring print quality. This is particularly suitable for processing wide-format paper that is not fully visible from the side of the equipment.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
