Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping machines, in particular to a hot stamping device for preventing hot stamping films from sticking. Background Art

[0002] Hot stamping is a special printing process that does not use ink. Hot stamping refers to the process of hot stamping electrochemical aluminum foil onto the surface of the substrate under a certain temperature and pressure. Hot stamping has been widely used in high-end, exquisite packaging decoration, trademarks, calendars, book covers and other printed materials.

[0003] In the continuous hot stamping process, the temperature of the hot stamping machine gradually increases, and it is difficult to fully cool down after hot stamping, resulting in the hot melt adhesive or heat transfer layer on the hot stamping film still being in a softened state, and then it is easy to stick to the surface of the hot stamped product after contact, affecting the effect of the finished product. For this reason, we proposed a hot stamping device that avoids the adhesion of the hot stamping film. Utility Model Content

DETAILED DESCRIPTION

[0020] See also Figure 1-Figure 5 A hot stamping device for preventing hot stamping film from sticking comprises a processing table 1, a hot stamping mechanism 2 is arranged above the processing table 1, and an anti-sticking mechanism 3 is fixed on the surface of the processing table 1;

[0021] The hot stamping mechanism 2 can perform hot stamping on the hot stamped product, and the anti-sticking mechanism 3 can prevent the hot stamping film from sticking due to high temperature.

[0022] The anti-sticking mechanism 3 includes a hot stamping table 301, which is fixed to the top of the processing table 1. An air cooling pipe 302 is fixed to the top of the hot stamping table 301. A plurality of exhaust pipes are provided on the surface of the air cooling pipe 302. A mounting frame 303 is fixed to the bottom of the processing table 1. Two second cylinders 304 are fixed to the surface of the mounting frame 303. One end of the second cylinder 304 passes through the mounting frame 303 and is fixed with a cooling shell 305. A through groove for the cooling shell 305 to pass through is provided on the surface of the processing table 1. A semiconductor refrigerator 306 is fixed to the bottom of the cooling shell 305. A cooling fan 307 is fixed to the bottom of the semiconductor refrigerator 306. A heat conducting pipe 308 is fixed inside the cooling shell 305. Both left and right ends of the heat conducting pipe 308 pass through the cooling shell 305. A fan 309 is fixed to the top of the processing table 1. A hose 310 is connected to the fan 309 and one end of the air cooling pipe 302. One end of the hose 310 passes through the processing table 1 and is connected to one end of the heat conducting pipe 308.

[0023] The surface of the hot stamping table 301 is used to place the hot stamping products. When the hot stamping plate 205 pushes the hot stamping film downward to fit the hot stamping products, the second cylinders 304 on both sides push up the cooling shell 305, so that the bottom of the cooling shell 305 fits the bottom of the hot stamping table 301. Since the semiconductor refrigerator 306 on the surface of the cooling shell 305 will cool the cooling shell 305 when it is working, the heat dissipation fan 307 can disperse the heat generated by the semiconductor refrigerator 306 when it is working, so that the cooling shell 305 can quickly cool the hot stamping table 301, which can help to quickly reduce the temperature of the hot stamping material, make it solidify faster, reduce the stickiness caused by residual heat, and thus avoid the hot stamping film from sticking to the hot stamped product. At the same time, the fan 309 can transport air to the inside of the heat guide pipe 308 through the hose 310. When the air When flowing through the cooled heat pipe 308, since the heat pipe 308 will absorb the cold on the surface of the cooling shell 305, the temperature of the air circulating inside the heat pipe 308 will also decrease, and the cooled air will be able to be introduced into the air cooling pipe 302 through the left hose 310. The exhaust pipe on the surface of the air cooling pipe 302 can blow cold air to the hot stamping area while the hot stamping plate 205 is lifted. The cold air can further accelerate the heat dissipation and help the material to reach a non-sticky state faster. At the same time, the cold air can also help to form an extremely thin air film, which reduces the direct contact between the hot stamping film and the hot stamping surface and prevents adhesion. Combining these two cooling measures can not only effectively control the temperature after hot stamping and prevent the hot stamping film from sticking due to overheating due to continuous hot stamping, but also improve production efficiency and ensure the quality and aesthetics of the hot stamping products.

[0024] Furthermore, the hot stamping mechanism 2 includes a support frame 201, which is fixed to the top of the processing table 1, a first cylinder 202 is fixed to the surface of the support frame 201, a movable frame 203 is fixed to one end of the first cylinder 202, a heating plate 204 is fixed to the bottom of the movable frame 203, a hot stamping plate 205 is fixed to the bottom of the heating plate 204, a fixed plate 206 is fixed to the surface of the support frame 201, motors 207 are fixed to the left and right sides of the fixed plate 206, and the output shaft of the motor 207 passes through the fixed plate 206 and is fixed to a loading shaft 208;

[0025] The surface of the loading shaft 208 can be used to place hot stamping film raw materials and collect hot stamping film waste. The motor 207 can drive the loading shaft 208 to rotate to realize the movement and transportation of the hot stamping film. The first cylinder 202 can push the movable frame 203 downward when started, so that the movable frame 203 can push the electric heating plate 204 and the hot stamping plate 205 to move synchronously. The electric heating plate 204 can heat the hot stamping plate 205, and the hot stamping plate 205 will squeeze the hot stamping film and the hot-stamped product together when it moves downward, thereby realizing hot stamping lamination.

[0026] Furthermore, a plurality of connecting plates 209 are fixed on the surface of the fixing plate 206, and a guide rod 210 is fixed on the surface of the connecting plate 209;

[0027] The guide rod 210 can help accurately guide the hot stamping film to ensure that it is correctly aligned when entering the hot stamping area, and ensure that the hot stamping film maintains good flatness and tension during the conveying process to avoid wrinkles or waves.

[0028] Furthermore, the surface of the loading shaft 208 is slidably connected to a limit plate 211, a fixing hole is provided on the surface of the limit plate 211, and a thread groove 212 is provided on the surface of the loading shaft 208;

[0029] The limiting plate 211 can slide on the surface of the loading shaft 208, and after the bolt is passed through the fixing hole and screwed into the threaded groove 212, the limiting plate 211 can be fixed, so that the hot stamping film raw material and the collected hot stamping film waste can be limited to prevent the loading shaft 208 from falling off during rotation.

[0031] After placing the stamped product on the surface of the hot stamping table 301, the vacuum pump 311 can extract the air inside the cavity to make the cavity in a negative pressure state, so that the cavity can adsorb the stamped product through the adsorption holes, avoiding the air blowing of the air cooling tube 302 and the displacement of the stamped product during the hot stamping process of the hot stamping plate 205.

[0032] Furthermore, a filter screen 312 is fixed to the inner wall of the cavity of the hot stamping station 301;

[0033] The filter screen 312 intercepts dust and impurities that enter the cavity through the adsorption holes, preventing them from entering the interior of the vacuum pump 311 and causing damage to the equipment.
