Description

Technical Field

[0001] This utility model relates to the field of hot stamping equipment technology, and more specifically, to a hot stamping machine for producing environmentally friendly paper boxes. Background Technology

[0002] A hot stamping machine is a device that transfers metal foil or pigment from hot stamping paper to the surface of a substrate through heat and pressure, thereby achieving a decorative or marking effect. It is widely used in printing, packaging, leather, plastics, electronics and other industries, and can form patterns or text with various lusters such as gold, silver and color on materials such as paper, cloth, leather, wood, plastic and metal.

[0003] A search revealed Chinese patent application number 202220512534.2, which discloses a hot stamping device for packaging cartons, relating to the field of hot stamping equipment technology. The hot stamping device for packaging cartons includes a frame with a top seat and a base at its upper and lower ends, respectively. A worktable is fixed on the base. Unwinding rollers and take-up rollers are respectively located on the left and right sides of the frame. A push rod motor and a guide shaft are mounted under the top seat. A pressure plate is slidably connected to the guide shaft, and the pressure plate is connected to the output end of the push rod motor. A hot stamping device is mounted under the pressure plate. Positioning rods are located at the four corners of the lower end face of the pressure plate, and positioning plates are slidably connected to the positioning rods. This invention, by setting positioning plates, allows the hot stamping device to contact and press the cartons first during the hot stamping process, pre-positioning the cartons and preventing displacement during the hot stamping process, thus ensuring the hot stamping effect. However, the aforementioned patents have the following shortcomings: during use, operators need to manually adjust the position of the carton to ensure precise alignment with the hot stamping device, making it impossible to quickly complete the positioning; furthermore, the hot stamping plate is fixed to the heating plate, making it inconvenient to disassemble and replace. Therefore, this utility model proposes a new solution. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] like Figures 1-5As shown, this embodiment proposes an environmentally friendly hot stamping machine for paper box production, including a frame 1. A base plate 2 and a top plate 3 are symmetrically mounted on the front of the frame 1. A lifting mechanism is installed at the bottom of the top plate 3. On both sides of the lifting mechanism are unwinding rollers 6 and rewinding rollers 7 mounted on the front of the frame 1. Adjusting guide rollers 8 are installed between the unwinding rollers 6 and rewinding rollers 7 and the lifting mechanism. A worktable 9 is located on the top of the base plate 2. Multiple limiting mechanisms 24 are movably mounted on the top of the worktable 9. Multiple grid-distributed insertion holes 13 are opened on the top of the worktable 9. The limiting mechanisms 24 are installed inside the insertion holes 13. By setting the insertion holes 13 and the limiting mechanisms 24, the positions of the multiple limiting mechanisms 24 can be adjusted according to the external contour of the carton or box during use, allowing the multiple limiting mechanisms 24 to position the carton from the outside. During hot stamping, simply pushing the carton between the multiple limiting mechanisms 24 quickly completes the positioning, making it simpler and more convenient to use. Simultaneously, the grid-distributed multiple insertion holes 13 allow for better positioning during use. The position of the limiting mechanism 24 can be flexibly adjusted to facilitate use with cartons of different sizes or shapes; a base plate 15 is installed at the bottom of the lifting mechanism, a heating plate 17 is fixedly installed at the bottom of the base plate 15, and a mounting frame 16 is bolted to the outside of the base plate 15. A hot stamping plate 18, which is in close contact with the bottom of the heating plate 17, is slidably installed on the inside of the mounting frame 16. Slide grooves 19 are provided on both sides of the hot stamping plate 18, and guide rails 20 that cooperate with the slide grooves 19 are fixedly installed on the inner wall of the mounting frame 16. The front of the 6 is equipped with a locking mechanism to limit the movement of the heating plate 17. By setting the mounting frame 16, the slide groove 19 and the guide rail 20, the hot stamping plate 18 can be slidably installed on the inner side of the mounting frame 16 through the slide groove 19 and the guide rail 20 during use. After installation, the locking mechanism can limit its position. When disassembly is required, simply rotate the limiting block 22 to move it away from the hot stamping plate 18 to pull the hot stamping plate 18 out from the inner side of the mounting frame 16, thereby facilitating the disassembly and replacement of the hot stamping plate 18.

[0028] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the locking mechanism further includes a mounting rod 21 fixedly installed on the front of the mounting frame 16, and a limiting block 22 rotatably mounted on the mounting rod 21. It should be noted that during use, rotating the limiting block 22 to block the front of the hot stamping plate 18 can limit the hot stamping plate 18.

[0029] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, the lifting mechanism further includes a cylinder installed at the bottom of the top plate 3. A mounting plate for mounting the substrate 15 is fixedly installed at the moving end of the cylinder, and a guide rod 5, slidably connected to the mounting plate, is fixedly installed at the bottom end of the top plate 3. The guide rod 5 is located on one side of the cylinder. It should be noted that the cylinder facilitates the vertical movement of the hot stamping plate 18, and the guide rod 5 guides the vertically moving mounting plate during use.

[0030] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, further, positioning rods 10 are installed at the four bottom corners of the mounting plate, positioning frames 11 are slidably installed on the positioning rods 10, and a first spring 12 is provided on the outer side of the positioning rods 10, connecting the mounting plate and the positioning frame 11. A positioning hole 23 is provided on the top of the worktable 9 to cooperate with the positioning rods 10. It should be noted that the positioning rods 10, positioning frames 11, and first springs 12 facilitate the pressing of the carton during hot stamping. The positioning holes 23 facilitate the guiding and limiting of the positioning rods 10. The positioning holes 23 are oblong, ensuring that the positioning rods 10 can still be inserted into the worktable 9 after displacement.

[0031] like Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, an adjustment mechanism 14 is further provided between the base plate 2 and the worktable 9. The adjustment mechanism 14 includes a first mounting groove 141 opened on the top of the base plate 2. The first mounting groove 141 is provided with a lead screw 143 rotatably connected to the base plate 2 inside. A first slider 144 for connecting the worktable 9 is installed on the outside of the lead screw 143. One end of the lead screw 143 is fixedly connected to a turntable 147 located on one side of the base plate 2. A second mounting groove 142 is provided on both sides of the first mounting groove 141. A slide rod 146 fixedly connected to the base plate 2 is provided inside the second mounting groove 142. A second slider 145 for connecting the worktable 9 is slidably installed on the outside of the slide rod 146. It should be noted that when in use, rotating the turntable 147 can drive the lead screw 143 to rotate, thereby driving the worktable 9 to move through the first slider 144, thus fine-tuning the position of the worktable 9 and the carton so that it can be accurately aligned with the hot stamping plate 18. When the worktable 9 moves, the slide bar 146 and the second slider 145 will guide it.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, in a preferred embodiment, based on the above method, the limiting mechanism 24 further includes a housing 241 movably installed inside the insertion hole 13. A limiting rod 242 is slidably installed inside the housing 241, and a second spring 243 connects the limiting rod 242 and the housing 241. It should be noted that during use, the limiting rod 242 protrudes from the insertion hole 13, thereby positioning the carton. When the hot stamping plate 18 or the positioning frame 11 presses against the limiting rod 242, it retracts into the housing 241, thereby avoiding affecting the movement of the hot stamping plate 18 or the positioning frame 11. After the hot stamping plate 18 or the positioning frame 11 resets, the limiting rod 242 is released from the top inside the housing 241 by the second spring 243.

[0033] Specifically, the working principle of this hot stamping machine for producing environmentally friendly paper boxes is as follows: Before use, the hot stamping foil roll is loaded onto the unwinding roller 6, one end of the hot stamping foil roll is pulled out, and then it is wound around the take-up roller 7. The take-up roller 7 can drive the hot stamping foil roll to roll. During use, the positions of multiple limiting mechanisms 24 can be adjusted according to the external contour of the carton or box, so that the multiple limiting mechanisms 24 position the carton from the outside. When hot stamping, simply push the carton between the multiple limiting mechanisms 24 to quickly complete the positioning, and then hot stamping... The printing plate 18 is slidably installed inside the mounting frame 16 via the slide groove 19 and guide rail 20. After installation, it is limited by the locking mechanism. When hot stamping, the carton is pushed into the multiple limiting mechanisms 24 on the worktable 9 to complete the positioning of the carton. Then, the hot stamping plate 18 is moved up and down by the cylinder to perform hot stamping operation. When disassembly is required, simply rotate the limiting block 22 to move it away from the hot stamping plate 18 to pull the hot stamping plate 18 out from the inside of the mounting frame 16, so that the hot stamping plate 18 can be easily disassembled and replaced.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
