Description

Technical Field

[0001] The utility model belongs to the technical field of printing, in particular to a high-precision regulating mechanism for a cooling roller of a hot stamping machine. Background Art

[0002] Hot stamping is a special printing process that does not use ink. Hot stamping refers to the process of hot stamping anodized aluminum foil onto the surface of the substrate under a certain temperature and pressure. Hot stamping machine is the equipment that completes the hot stamping process.

[0003] At present, when traditional hot stamping machines perform hot stamping processes, ensuring the perfection of the hot stamping effect and the stability of the materials is the key to the process. The hot stamping process involves applying high temperature and pressure to the surface of the material to tightly adhere the metal foil or other decorative materials to the material to create a unique visual effect. However, in this process, the high temperature state of the material often causes it to deform during the cooling process. In order to effectively solve the problem of material deformation, traditional hot stamping machines generally use cooling rollers to quickly reduce the temperature of the material. The function of the cooling roller is to quickly absorb the heat of the material through the cooling medium (such as cooling water) on its surface, so that the material can be quickly cooled and the deformation phenomenon can be reduced. However, in actual operation, the existing technology has many inconveniences in fine-tuning the lifting and lowering of the cooling roller. The cooling roller lifting mechanism may adopt manual or simple mechanical transmission methods, which are cumbersome to operate and have limited accuracy. This adjustment method is not only inefficient, but also easily affected by human factors, resulting in unstable adjustment results, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5As shown, the utility model provides a high-precision adjustment mechanism for the cooling roller of a hot stamping machine, comprising a base 1, a limit rod 2 is fixedly installed on the top of the base 1, a lifting plate 3 is slidably connected to the surface of the limit rod 2, a driving assembly 4 is arranged on the top of the lifting plate 3, a driving gear 5 is arranged on the output end of the driving assembly 4, a support rod 6 is arranged on the top of the driving assembly 4, a driven gear 7 is rotatably connected to the front side of the top of the support rod 6, a driving chain 8 is transmission-connected to the surface of the support rod 6 and the driven gear 7, a rotating rod 10 is fixedly installed on the front end of the driving chain 8, a supporting sleeve 9 located on the surface of the rotating rod 10 is fixedly installed on the side of the top of the support rod 6, and a mounting sleeve 11 located inside the supporting sleeve 9 is fixedly installed on the surface of the rotating rod 10;

[0023] The adjusting mechanism is arranged at the bottom end of the lifting plate 3, and the adjusting mechanism includes a connecting plate 12, which is fixedly connected to the bottom end of the lifting plate 3. A through hole 13 is opened on the surface of the connecting plate 12. A slide rail 14 located at the rear end of the connecting plate 12 is fixedly installed on the top of the base 1, and a slide plate 15 is slidably connected on the surface of the slide rail 14. A mounting plate 16 is fixedly installed on the top of the slide plate 15, and a slider 17 located inside the through hole 13 is fixedly installed on the front end of the mounting plate 16. A transmission wheel 18 located at the rear end of the slide plate 15 is rotatably connected to the top of the base 1. There are two transmission wheels 18, and the surfaces of the two transmission wheels 18 are transmission-connected with a synchronous belt 19. A motor 20 is arranged at the rear end of the right-end transmission wheel 18, and the output end of the motor 20 is fixedly connected to the rear end of the right-end transmission wheel 18. A connecting plate 21 is fixedly installed on the front side of the top of the synchronous belt 19, and the front end of the connecting plate 21 is fixedly connected to the rear end of the slide plate 15.

[0024] The above scheme is adopted: the operator installs the device on the hot stamping machine, and then the cooling roller can be inserted into the inside of the mounting sleeve 11, and then the cooling roller can be fixed inside the mounting sleeve 11, and then the motor 20 can be driven to rotate the transmission wheel 18 at the right end. Since the surfaces of the two transmission wheels 18 are connected with the synchronous belt 19, the transmission wheel 18 at the right end will drive the synchronous belt 19 and the transmission wheel 18 at the left end to rotate, and then the rotating synchronous belt 19 will drive the connecting plate 2 21 to move left, and the connecting plate 2 21 will move on the surface of the slide rail 14 on the slide 15, and the slide 15 will drive the mounting plate 16 and the slider 2 17 to move, and the slider 2 17 will move inside the through hole 13. Since the through hole 13 is designed to be inclined, the slider 2 17 will push the connecting plate 1 12 to move up during the movement inside the through hole 13, and the connecting plate 1 12 will drive the lifting plate 3 to move on the surface of the limit rod 2, and then the lifting plate 3 can drive the cooling roller to move up, and then the cooling roller can be moved to the specified position;

[0025] When the cooling roller moves to a specified position, the movement of the motor 20 can be stopped, and then the transmission wheel 18 at the right end will stop rotating. Since the teeth on the surface of the transmission wheel 18 engage with the teeth inside the synchronous belt 19, when the transmission wheel 18 stops rotating, the synchronous belt 19 will be locked on the surface of the transmission wheel 18 and cannot slide or reverse by itself. This self-locking function ensures that the synchronous belt 19 can remain stable in the stopped state, and avoids the reversal of the synchronous belt 19 due to unexpected factors, which causes the position of the cooling roller to shift. After the cooling roller is adjusted, the drive assembly 4 can be driven to rotate the drive gear 5. Since the drive gear 5 is connected to the surface of the support rod 6 by a drive chain 8, the drive gear 5 will drive the drive chain 8 and the support rod 6 to rotate, and the support rod 6 will drive the rotating rod 10 and the mounting sleeve 11 to rotate, and the mounting sleeve 11 will drive the cooling roller to rotate, thereby improving the efficiency of the rotation control of the cooling roller.

[0026] like Figure 2 and Figure 5 As shown, the top and bottom ends of the mounting sleeve 11 are provided with a socket 22, the internal threads of the socket 22 are connected with a threaded rod 23, the front and rear ends of the surface of the slide rail 14 are provided with a limit groove 24, and the interior of the slide plate 15 is fixedly installed with a limit block 25 located inside the limit groove 24, and the surface of the limit block 25 is fully fitted with the inner wall of the limit groove 24.

[0027] The above scheme is adopted: through the design of the socket 22 and the threaded rod 23, after the cooling roller is inserted into the interior of the mounting sleeve 11, the threaded rod 23 can be inserted into the interior of the socket 22, and then the threaded rod 23 is rotated, and then the surface of the threaded rod 23 will enter the interior of the cooling roller, thereby fixing the cooling roller, and through the design of the limiting groove 24 and the limiting block 25, when the slide plate 15 moves, the slide plate 15 will drive the limiting block 25 to move inside the limiting groove 24, because the surface of the limiting block 25 is fully fitted with the inner wall of the limiting groove 24, the slide plate 15 can be smoothly moved on the surface of the slide rail 14, and the slide plate 15 can be limited.

[0028] like Figure 1 and Figure 5 As shown, threaded holes 26 are provided on the surface of the base 1, and the number of threaded holes 26 can be designed according to demand. A baffle is provided on the surface of the slider 17, and the opposite sides of the baffle are in contact with the front and rear sides of the connecting plate 12.

[0029] The above scheme is adopted: through the design of the threaded hole 26, when the device is placed at the position where it needs to be installed, the fixing screw can be inserted into the threaded hole 26, and then the device can be fixed on the hot stamping machine, and the number of threaded holes 26 can be designed according to needs, so as to increase the stability of the equipment installation. Through the design of the slider 17, since a baffle is provided on the surface of the slider 17, and the opposite side of the baffle is in contact with the front and rear sides of the connecting plate 12, when the slider 17 moves, the slider 17 can be limited, so that the slider 17 can smoothly drive the connecting plate 12 to move.

[0030] like Figure 1 and Figure 5 As shown, the limit rod 2 is of cylindrical design, and the limit rod 2 is of transverse symmetrical design about the center of the base 1. A circular plate is provided at the top of the limit rod 2, and the size of the circular plate is larger than the size of the limit rod 2. The slider 17 is of cylindrical design, and the surface of the slider 17 is fully fitted with the inner wall of the through hole 13.

[0031] The above scheme is adopted: through the design of the limit rod 2, since the limit rod 2 is symmetrically designed, when the lifting plate 3 moves, the limit rod 2 can limit the lifting plate 3, so that the lifting plate 3 can move stably, and a circular plate is provided at the top of the limit rod 2, and the size of the circular plate is larger than the limit rod 2, so that the movement of the lifting plate 3 can be blocked to prevent the lifting plate 3 from moving out of the surface of the limit rod 2. Through the design of the slider 17, since the slider 17 is cylindrical and the size of the slider 17 is adapted to the through hole 13, the slider 17 is convenient to move inside the through hole 13.

[0032] The working principle and use process of this utility model:

[0033] First, the operator can insert the cooling roller into the mounting sleeve 11, and then insert the threaded rod 23 into the socket 22, so as to fix the cooling roller inside the mounting sleeve 11. Then the mechanism can be installed on the hot stamping machine, and then the motor 20 can be driven to rotate the transmission wheel 18 at the right end, and then the transmission wheel 18 at the right end will drive the synchronous belt 19 and the transmission wheel 18 at the left end to rotate, and then the synchronous belt 19 will drive the connecting plate 21 and the slide plate 15 to move, and the slide plate 15 will drive the mounting plate 16 and the slider 2 17 to move. When the slider 2 17 moves, it will push the connecting plate 1 12 and the lifting plate 3 to move upward, and then the lifting plate 3 will drive the cooling roller to move upward, and then move the cooling roller to the specified position, and then the motor 20 can be stopped, and then the driving assembly 4 can be driven to rotate the driving gear 5, and the driving gear 5 will drive the driven gear 7 and the driving chain 8 to rotate, and then the driven gear 7 will drive the cooling roller to rotate, so as to cool the workpiece, and through the rotation of the cooling roller, the efficiency of the rotation control of the cooling roller is improved, and finally the operation process is completed.
