Description

Technical Field

[0001] This utility model relates to the field of coated paper technology, specifically to a device for hot-stamping holes in coated paper. Background Technology

[0002] Laminated paper is a special type of paper with a plastic film coated on its surface, widely used in packaging, printing, and other fields. In some applications, laminated paper requires perforation to facilitate ventilation, drainage, or other functions. Existing perforation methods generally include the following two types:

[0003] 1. Using a punching needle to make holes will cause burrs and sharp corners to appear on the edges of the holes in the coated paper, making the coated paper prone to cracking during use.

[0004] 2. High-temperature heat-conducting oil is used for hot-dip pores, but the heat-conducting oil is prone to flow out during the processing, contaminating the surface of the coated paper and thus affecting the processing quality of the coated paper.

[0005] Therefore, improvements are needed to address the aforementioned issues. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0020] See Figure 1A hot stamping device for coated paper includes a processing platform 1 and a hot stamping mechanism 2. The upper surface of the processing platform 1 has an installation groove 3. Multiple springs 4 are arranged at the bottom of the installation groove 3. The top of the springs 4 is provided with the same buffer platform 5. The upper surface of the buffer platform 5 has a row of holes 6. The hot stamping mechanism 2 includes a gantry frame 21. A pressing cylinder 22 is provided on the gantry frame 21. The piston rod end of the pressing cylinder 22 is provided with a housing 23. A heating plate 24 is provided inside the housing 23. A row of heat-conducting rods 25 is provided at the bottom of the housing 23. The heat-conducting rods 25 are connected to the heating plate 24. The heat-conducting rods 25 correspond one-to-one with the holes 6. A clamping mechanism 7 is provided on the left and right sides of the housing 23. Specifically, when the coated paper is placed on the buffer table 5, the pressing cylinder 22 is activated, driving the heat-conducting rod 25 to press down (at this time, the heating plate 24 has already heated the heat-conducting rod 25), which cooperates with the groove 6 to heat the coated paper; the buffer table 5 is buffered by the action of the spring 4 to prevent the heat-conducting rod 25 from colliding hard with the groove 6 and causing damage to the heat-conducting rod 25; the pressing mechanism 7 is used to press the two sides of the coated paper, cooperate with the heat-conducting rod 25 to heat the holes, and ensure the flatness of the heat-heated holes.

[0021] In this embodiment, limiting grooves 51 are formed on the left and right sides of the buffer platform 5, and guide posts 52 are set inside the limiting grooves 51. At the same time, guide rings 53 are set on the left and right inner walls of the mounting groove 3, and the guide rings 53 are fitted onto the guide posts 52. When the buffer platform 5 moves down, the guide rings 53 limit the descent distance of the limiting grooves 51, that is, limit the downward movement of the buffer platform 5 to avoid moving down too much, which would cause the coating paper to bend too much; the downward movement distance is controlled within 2-5 mm.

[0022] In this embodiment, an insulation layer 26 is provided on the outside of the heating plate 24. The insulation layer 26 keeps the heating plate 24 warm, ensuring that the long heat-conducting rod 25 is effective for a long time.

[0023] In this embodiment, the pressing mechanism 7 includes a limiting plate 71 fixed to the outer wall of the outer casing and a slide rail assembly 72. A lifting plate 73 is provided on the slider of the slide rail assembly 72, and a return spring 74 is provided between the lifting plate 73 and the limiting plate 71. A pressure roller 75 is provided below the lifting plate 73. When the heat-conducting rod 25 moves down to heat the holes, the pressing mechanism 7 also moves down accordingly. Under the action of the return spring 74 and the slide rail assembly 72, the pressure roller 75 presses down on both sides of the coated paper, cooperating with the heat-conducting rod 25 to heat the holes and ensure the flatness of the heat-heated holes.

[0024] In this embodiment, a telescopic guide post 8 is provided between the gantry frame 21 and the outer casing 23. The telescopic guide post 8 improves the stability of the lifting and lowering of the outer casing 23, which in turn improves the stability of the heat-conducting rod 25.

[0025] In this embodiment, an air blowing hole 9 is provided at the bottom of the slot 6, and an air pipe 10 is provided at the bottom of the air blowing hole 9. The air pipe is connected to a solenoid valve 11 and an air pump 12. If there are debris at the bottom of the slot 6, air can be blown into the slot 6 through the air pump 12, the air pipe 10 and the air blowing hole 9 to blow the debris out; at the same time, if the air pressure is strong enough, the debris remaining on the heat-conducting rod 25 can be blown off.

[0026] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
