[0002] Hot stamping film refers to a technology that combines laser holographic electroplated aluminum film with hot stamping technology to form colorful laser holographic logos and three-dimensional patterns on the surface of printed materials as anti-counterfeiting marks. This technology can add laser encryption and a back anti-tamper layer for the anti-counterfeiting of documents, cards, tickets, trademarks, etc. In the processing of some paper and board materials, printing equipment is required to attach hot stamping film to their outer surface to achieve the anti-counterfeiting function.

In this utility model, by setting a connecting plate and a rectangular limiting block, the operator can rotate the protective plate, thereby rotating it 90 degrees to achieve storage of the rotating protective plate and protect the sides of the printing device body, thus effectively improving the reliability of the device during use. The inclusion of a moving block and a limiting plate ensures that the material to be printed is always printed from the center of the rotating protective plate, guaranteeing the quality of the finished product during the printing process and effectively improving the yield rate of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6This utility model provides a printing device for thermochromic anti-counterfeiting hot stamping film, including a printing device body 1. The printing device body 1 has discharge slots on both sides, allowing the limiting plate 12 to be stored inside the support plate 4 through the discharge slots, ensuring unrestricted storage of the limiting plate 12. Supports 2 are fixedly installed at the bottom of both sides of the printing device body 1. A rotating rod 3 is rotatably installed in the middle of the support 2, with rings 6 fixed at both ends of the rotating rod 3. The support plate 4 is fixedly installed in the middle of the rotating rod 3. Boxes 5 are fixedly installed on both sides of the support 2. Insertion rods 7 are slidably installed inside the boxes 5. Two insertion holes are opened on the surface of the rings 6 to engage with the insertion rods 7. Through the stretching and movement of the insertion rods 7, the sliding strip 8 is positioned outside the boxes 5, at which point the insertion rods 7 and the insertion holes are separated. The insertion rod 7 is rotated, releasing the pull cap 16. Under the action of the spring 10 and the slide plate 9, the slide bar 8 supports and limits the surface of the box 5, thus facilitating the limitation of the insertion rod 7 during the stretching process. This makes the operation convenient and reduces the difficulty of operation for users when adjusting or storing the support plate 4. Two slide bars 8 are fixed in the middle of the insertion rod 7, and the slide plate 9 is rotatably provided at the end of the insertion rod 7. The surface of the insertion rod 7 is fitted with a spring 10. The middle of the support plate 4 is rotatably provided with a lead screw 11, and both ends of the lead screw 11 are threadedly connected to the limit plates 12 through the lead screw nut. By rotating and adjusting the lead screw 11, the two limit plates 12 on the surface of the lead screw 11 can be moved in opposite directions, thereby enabling quick adjustment of the distance between the two limit plates 12.

[0020] One end of the insertion rod 7 is fixedly provided with a pull cap 16, the slide bar 8 is slidably connected to the box body 5, one end of the spring 10 is in contact with one side of the slide plate 9, and the other end is in contact with the inner wall of the box body 5, and the included angle between the two insertion holes is set at ninety degrees; by pulling the pull cap 16, the insertion rod 7 can be stretched and moved, and by rotating the pull cap 16, the insertion rod 7 can be rotated, which in turn can drive the two slide bars 8 on the surface of the insertion rod 7 to rotate.

[0021] Two guide rods 15 are symmetrically slidably provided at the bottom of the slide plate 9. Both ends of the guide rods 15 are fixedly connected to the inner wall of the box body 5. The two guide rods 15 provided at the slide plate 9 allow the slide plate 9 to move without any restriction.

[0022] The threads at both ends of the lead screw 11 rotate in opposite directions, and the limiting plate 12 is slidably connected to the support plate 4. Because the threads at both ends of the lead screw 11 rotate in opposite directions, the two limiting plates 12 on the surface of the lead screw 11 move synchronously in opposite directions. The sliding connection between the limiting plate 12 and the support plate 4 allows the limiting plate 12 to move and be adjusted without any restriction.

[0023] An adjustment assembly 13 is provided in the middle of one side of the support plate 4. The adjustment assembly 13 includes a housing 1301, which is fixedly installed in the middle of one side of the support plate 4. One end of the lead screw 11 passes through the support plate 4 and is fixedly connected to the worm gear 1302 provided inside the housing 1301. A worm 1303 is meshed and connected below the worm gear 1302. One end of the worm 1303 passes through the housing 1301 and is fixedly provided with a knob 1304. The other end of the worm 1303 is rotatably connected to the inner wall of the housing 1301. Through the adjustment assembly 13, the knob 1304 can be used to drive the worm 1302 to rotate, thereby driving the meshed worm gear 1303 and the lead screw 11 to rotate synchronously and adjust, so that the limiting plate 12 on the surface of the lead screw 11 can be moved and adjusted to achieve the limiting of the material to be printed.

[0024] Two limiting rods 14 are symmetrically slidably provided at the bottom of the two limiting plates 12, and both ends of the limiting rods 14 are fixedly connected to the inner wall of the support plate 4. By sliding the two limiting rods 14 at the two limiting plates 12, the limiting plates 12 can play a guiding role in moving.

[0025] Support seats 17 are fixedly provided on both sides of the bottom end of the printing device body 1, and support pads are fixedly provided at the bottom end of the support seats 17; the support seats 17 and support pads are provided on both sides of the bottom end of the printing device body 1, thereby enhancing the stability of the overall structure.

[0026] In use, when the support plate 4 needs to be rotated and adjusted, the pull cap 16 is stretched to separate the insertion rod 7 from one of the insertion holes. At this time, the slide bar 8 on the surface of the insertion rod 7 is located outside the box body 5. Rotating the insertion rod 7 releases the pull cap 16. Under the action of the spring 10 and the slide plate 9, the insertion rod 7 is limited in the horizontal direction. At this time, one side of the slide bar 8 abuts against the surface of the box body 5. Repeat the above operation steps to limit the insertion rod 7 in another position. Then, the support plate 4 is rotated 90 degrees by the rotating rod 3. Rotating the pull cap 16 causes the slide bar 8 to slide into the box 5. With the support and rebound of the spring 10, the insertion rod 7 is inserted into another insertion hole, thus realizing the limited storage of the support plate 4, making it more convenient to use. When it is necessary to adjust the distance between the two limiting plates 12, the knob 1304 drives the worm gear 1302 to rotate, which drives the meshing worm wheel 1303 and the lead screw 11 to rotate synchronously, so that the limiting plate 12 on the surface of the lead screw 11 can move and adjust to achieve the limiting of the material to be printed.

[0027] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
