Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping devices, in particular to a fast and accurate positioning hot stamping device. Background Art

[0002] The hot stamping process is a process for printing the electrochemical aluminum foil pattern on the hot stamping film onto the substrate through a certain temperature and pressure. The pattern printed on the electrochemical aluminum foil has a strong metallic luster, bright colors, never fades, and has good ornamental value. For example, the hot stamping device is needed for hot stamping in the production process of toy stickers.

[0003] In order to improve the accuracy of hot stamping, the prior art has made many improvements to hot stamping devices. For example, patent publication number CN216635860U discloses a hot stamping machine with a positionable support for sticker production, including a column, a transmission control mechanism, and a lifting transmission mechanism. The lower bottom of the column is provided with a base plate, the outer two sides of the column are provided with a transmission control mechanism, the front side of the column is provided with a lifting transmission mechanism, and the front top of the column is provided with a hot stamping device. The lifting transmission mechanism includes a workbench, an auxiliary roller, a limit slider, a mosaic plate, and a hydraulic rod. The hot stamping machine with a positionable support for sticker production adopts the mutual cooperation between multiple mechanisms and has strong functionality. It can stably transmit the substrate under the action of the roller, and use the liftable workbench to drive the substrate to move upward, so that the auxiliary roller can stretch the substrate inward to achieve the purpose of tightening the substrate and make it flat on the workbench, making the hot stamping process more accurate and the image and text brighter and clearer.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative documents, the working table is moved upward and the roller parts on both sides are coordinated to achieve the effect of tightening the substrate, thereby improving the accuracy of the hot stamping position. However, in reality, the above-mentioned comparative documents only tighten the substrate in the length direction. There may be wrinkles in the width direction of the substrate during the transmission process. If there are wrinkles in the width direction at the hot stamping position, it will also affect the hot stamping accuracy of the substrate. Therefore, this field urgently needs to improve the hot stamping device to solve the defects of the existing technology. Utility Model Content

[0015] 1. In the utility model, the driving unit drives the upper fixed plate and the lower working table to move simultaneously. The upper side of the middle convex roller is higher than the upper side of the lower working table. Therefore, the middle position of the middle convex roller first contacts the lower side of the substrate, and the middle convex roller is larger at both ends and smaller in the middle, so it will lift the middle position of the substrate and then unfold the substrate. When the substrate is tightened by tension, the middle convex roller moves downward in the open groove, and the substrate is flat on the lower working table. At this time, the upper fixed plate drives the hot stamping device to move downward to the upper side of the substrate to complete the hot stamping operation on the substrate, thereby improving the hot stamping accuracy. At the same time, upper fixed plates and lower working tables are provided on both sides of the vertical supporting column, which can perform hot stamping operations at the same time and improve hot stamping efficiency.

[0016] 2. In the utility model, when the central convex roller is subjected to the tension of the printing material, the central convex roller moves downward in the open groove, and the central convex roller drives the first movable block to move downward in the first movable groove. At this time, the first spring is compressed. When the lower working table moves downward, the tension of the first spring pushes the first movable block to move upward, restoring the central convex roller to its original state. The first guide column prevents the first spring from radial deformation, thereby extending the service life of the first spring.

[0017] 3. In the present invention, when the lower workbench rises, the two first auxiliary rollers press on the upper side of the printing substrate. When the printing substrate is subjected to excessive force, the first auxiliary rollers drive the second movable block to move in the second movable groove. At this time, the second spring is compressed to prevent the printing substrate from being damaged by the pulling force.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1-Figure 5 A fast and precise positioning hot stamping device comprises a base 1 and a hot stamping device 5 for hot stamping. A vertical supporting column 2 is fixedly installed on the upper part of the base 1. An upper fixed plate 3 and a lower working table 4 are provided on the opposite sides of the vertical supporting column 2. The hot stamping device 5 is fixedly installed on the lower part of the upper fixed plate 3. The vertical supporting column 2 is provided with a driving unit 6 for simultaneously driving the upper fixed plate 3 and the lower working table 4 to move toward or away from each other. Open grooves 7 are provided on the opposite sides of the lower working table 4. A central convex roller 8 that can move up and down is rotatably connected in the open groove 7. The central convex roller 8 is small at both ends and large in the middle. Transmission rollers 9 are provided on the opposite sides of the vertical supporting column 2.

[0028] Specifically, the hot stamping device 5 is an existing public technology. It stamps the electrochemical aluminum foil onto the surface of the substrate under a certain temperature and pressure. The substrate is wound on the transmission roller 9 and is intermittently pulled by an external traction device. When the substrate needs to be hot stamped, the drive unit 6 is started. The drive unit 6 drives the upper fixed plate 3 and the lower working table 4 to move simultaneously. The upper side of the middle convex roller 8 is higher than the upper side of the lower working table 4. Therefore, the middle position of the middle convex roller 8 first contacts the lower side of the substrate. The middle convex roller 8 is large at both ends and small in the middle, so it will lift up the middle position of the substrate and then unfold the substrate. When the substrate is tightened by tension, the middle convex roller 8 moves down in the opening groove 7, and the substrate is flat on the lower working table 4. At this time, the upper fixed plate 3 drives the hot stamping device 5 to move down to the upper side of the substrate to complete the hot stamping operation on the substrate and improve the hot stamping accuracy. At the same time, upper fixed plates 3 and lower working tables 4 are provided on both sides of the vertical supporting column 2, which can perform hot stamping operations at the same time and improve hot stamping efficiency.

[0029] As a technical optimization solution of the present invention, the driving unit 6 includes a driving motor 10 fixedly installed on the upper part of the vertical supporting column 2, an upper sliding block 11 is fixedly connected between the two upper fixed plates 3, and a lower sliding block 12 is fixedly connected between the two lower working platforms 4. The vertical supporting column 2 has sliding grooves 13 adapted to the upper sliding block 11 and the lower sliding block 12 on the opposite sides. A bidirectional screw rod 14 with one end fixedly installed on the output end of the driving motor 10 is rotatably connected in the sliding groove 13. When the bidirectional screw rod 14 rotates, it drives the upper sliding block 11 and the lower sliding block 12 to move toward or away from each other at the same time.

[0030] Specifically, the threads of the bidirectional screw 14 located in the sliding groove 13 are opposite and symmetrical. The drive motor 10 is started, and the output end of the drive motor 10 drives the bidirectional screw 14 to rotate. When the bidirectional screw 14 rotates, it drives the upper sliding block 11 and the lower sliding block 12 to move toward or away from each other in the sliding groove 13, and the upper fixed plate 3 and the lower work table 4 move at the same time. Compared with moving only one upper fixed plate 3 or lower work table 4, the moving stroke is reduced, thereby improving the hot stamping efficiency.

[0031] As a technical optimization solution of the present invention, a first movable groove 15 is provided on the opposite side walls of the opening groove 7, and the two ends of the middle convex roller 8 are rotatably connected with a first movable block 16 adapted to the first movable groove 15. A first elastic spring 17 is provided between the first movable block 16 and the inner side wall of the first movable groove 15, and a first guide column 24 that passes through the first movable block 16 is fixedly connected between the upper and lower side walls of the first movable groove 15, and the first spring 17 is sleeved on the side of the first guide column 24.

[0032] Specifically, when the middle convex roller 8 is subjected to the tensioning force of the printing material, the middle convex roller 8 moves downward in the opening groove 7, and the middle convex roller 8 drives the first movable block 16 to move downward in the first movable groove 15. At this time, the first spring 17 is compressed. When the lower working table 4 moves downward, the tension of the first spring 17 pushes the first movable block 16 to move upward, restoring the middle convex roller 8 to its original state. The first guide column 24 prevents the first spring 17 from radial deformation, thereby extending the service life of the first spring 17.

[0033] As a technical optimization solution of the present invention, the transmission roller member 9 includes a fixed rod 22 fixedly installed on the opposite side of the vertical supporting column 2, and the opposite sides of the fixed rod 22 are provided with a rotatable first auxiliary roller 18 and a second auxiliary roller 19, and a second movable block 20 is rotatably connected between the two symmetrical second auxiliary rollers 19. A second movable groove 21 adapted to the second movable block 20 is opened through the opposite side of the fixed rod 22, and an elastic second spring 23 is provided between the side of the second movable block 20 and the inner wall of the second movable groove 21. The upper side of the second movable block 20 is fixedly connected to a second guide column 25 that passes through the upper part of the fixed rod 22, and the second spring 23 is sleeved on the side of the second guide column 25.

[0034] Specifically, the substrate is as Figure 1 It is coiled between several first auxiliary rollers 18 and second auxiliary rollers 19. When the lower workbench 4 rises, the two first auxiliary rollers 18 press on the upper side of the printing substrate. When the printing substrate is subjected to too much force, the first auxiliary roller 18 will drive the second moving block 20 to move in the second moving groove 21. At this time, the second spring 23 is compressed to prevent the printing substrate from being damaged by the tension. The second guide column 25 prevents the second spring 23 from radial deformation.

They are mature technologies and have been fully disclosed, so they are not repeated in the specification.
