Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap hot stamping, in particular to a hot stamping machine capable of performing all-round hot stamping on the side surface of a bottle cap. Background Technique

[0002] The hot stamping process is a special printing process without using ink. The so-called hot stamping refers to the process of hot stamping an aluminized foil onto the surface of a printing substrate under certain temperature and pressure. The hot stamping machine is the equipment for completing the hot stamping process. The hot stamping process is widely used in the production of bottle caps. When it is necessary to print the own logo on the side surface of the bottle cap, the hot stamping technology is required. However, after the existing hot stamping equipment fixes the bottle cap, it uses the hot stamping mechanism to press down and print the pattern on the aluminized foil on the side surface of the bottle cap. If the length of the hot stamping pattern is relatively long, the pattern cannot be completely printed on the side surface of the bottle cap. Therefore, we introduce a hot stamping machine capable of performing all-round hot stamping on the side surface of the bottle cap.

[0003] The existing technology has the following problems: 1. After the existing hot stamping equipment fixes the bottle cap, it uses the hot stamping mechanism to press down and perform hot stamping on the bottle cap. If the length of the hot stamping pattern is relatively long, the pattern cannot be completely printed on the side surface of the bottle cap; 2. When the existing bottle cap hot stamping equipment is working, it is necessary to wait for the previous bottle cap to complete hot stamping, then remove the hot stamped bottle cap, then fix the next bottle cap, and then perform hot stamping, resulting in a long waiting time and low efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hot stamping machine capable of performing all-round hot stamping on the side surface of a bottle cap, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hot stamping machine capable of performing all-round hot stamping on the side surface of a bottle cap, including a support table. A rotating assembly is arranged in the middle of the top surface of the support table. One side of the top surface of the support table is fixedly connected with a central control arm. A hot stamping mechanism is fixedly connected to the side of the central control arm close to the rotating assembly through a hydraulic arm. An inner support assembly is arranged inside the top of the rotating assembly;

[0006] The inner support assembly includes a hydraulic rod and a fixed cylinder fixedly connected inside the top of the rotating assembly. The output end of the hydraulic rod is rotatably connected with a rotating rod. One end of the rotating rod away from the hydraulic rod is fixedly connected with a first moving ring. Four active rods are hinged to one side of the first moving ring. One end of each of the four active rods away from the first moving ring is hinged with a driven rod. One end of the driven rod away from the active rod is hinged with a second moving ring. Four limiting blocks are fixedly connected to the side of the second moving ring close to the driven rod.

[0007] Further preferably, the number of the driven rods is four, and the four driven rods are angularly distributed on one side of the second moving ring. The four limit blocks correspond to the four driven rods one by one, and the limit blocks are arranged at the hinge points of the driven rods and the second moving ring.

[0008] Further preferably, a guiding groove is formed on the surface of the fixed cylinder. The guiding groove is composed of a straight groove section and a spiral groove section, and the number of turns of the spiral groove is one. The rotating rod is slidably connected to the inner side of the guiding groove, and the external dimension structure of the rotating rod is consistent with the internal dimension structure of the guiding groove.

[0009] Further preferably, a fixing piece is fixedly connected to one end of the fixed cylinder away from the hydraulic rod. A spring is fixedly connected to the edge of one side of the fixing piece connected to the fixed cylinder, and an abutting ring is fixedly connected to the end of the spring away from the fixing piece.

[0010] Further preferably, four balls are embedded on one side of the abutting ring away from the spring, and the four balls are all in contact with one side of the second moving ring.

[0011] Further preferably, the inner diameters of the first moving ring, the second moving ring and the abutting ring are all larger than the outer diameter of the fixed cylinder.

[0012] Further preferably, the rotating assembly includes a support shaft rotatably connected to the middle of the top surface of the support table. A sub-gear is fixedly connected to the top end of the support shaft, and a rotating table is fixedly connected to the top of the sub-gear.

[0013] Further preferably, one sides of the four mounting plates close to the middle of the rotating table are respectively fixed to the hydraulic rod and the fixed cylinder.

[0014] Further preferably, a main gear is meshed with one side of the sub-gear. The middle of the bottom surface of the main gear is fixedly connected to the output end of the servo motor. The servo motor is fixedly connected to the top surface of the support table, and the transmission ratio of the main gear to the sub-gear is 1:4.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, the inner support assembly is used to internally support and fix the bottle cap, and the stamping mechanism above is used to stamp the bottle cap. This method is applicable to stamping of smaller patterns. When a long pattern needs to be stamped, the cylinder continues to extend, which will drive the bottle cap to rotate around the axis of the fixed cylinder, and the stamping mechanism will also move synchronously with the bottle cap under the action of the hydraulic arm. At this time, the long pattern can be stamped on the side of the bottle cap to achieve 360° stamping of the bottle cap.

[0017] In this utility model, after a bottle cap is hot stamping completed, the servo motor is started to drive the main gear at the output end to rotate one circle. The rotation of the main gear will drive the driven gear meshed with it to rotate around the support shaft. At this time, the rotating table at the top of the driven gear also rotates accordingly. Since the transmission ratio of the main gear and the driven gear is 1:4, when the main gear rotates one circle, the driven gear will drive the rotating table to rotate 90°, sending the next bottle cap to be hot stamped under the hot stamping mechanism, saving the time for waiting for blanking and loading, and improving the hot stamping efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technical staff in the art without creative work fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a hot stamping machine capable of performing all-round hot stamping on the side of a bottle cap, including a support table 1. A rotating assembly 2 is provided in the middle of the top surface of the support table 1. One side of the top surface of the support table 1 is fixedly connected with a central control arm 3. One side of the central control arm 3 close to the rotating assembly 2 is fixedly connected with a hot stamping mechanism 4 through a hydraulic arm. An inner support assembly 5 is provided inside the top of the rotating assembly 2;

[0026] The inner support assembly 5 includes a hydraulic rod 501 and a fixed cylinder 502 fixedly connected to the inner side of the top of the rotating assembly 2. The output end of the hydraulic rod 501 is rotatably connected to a rotating rod 503. One end of the rotating rod 503 away from the hydraulic rod 501 is fixedly connected to a first moving ring 504. Four driving rods 505 are hinged to one side of the first moving ring 504. One end of each of the four driving rods 505 away from the first moving ring 504 is hinged to a driven rod 506. One end of the driven rod 506 away from the driving rod 505 is hinged to a second moving ring 507. Four limiting blocks 508 are fixedly connected to one side of the second moving ring 507 close to the driven rod 506. The number of driven rods 506 is four, and the four driven rods 506 are equally angularly distributed on one side of the second moving ring 507. The four limiting blocks 508 correspond to the four driven rods 506 one by one, and the limiting blocks 508 are arranged at the hinge points of the driven rods 506 and the second moving ring 507. A guiding groove 509 is formed on the surface of the fixed cylinder 502. The guiding groove 509 is composed of a straight groove section and a spiral groove section, and the number of turns of the spiral groove is one. The rotating rod 503 is slidably connected to the inside of the guiding groove 509. The external dimension structure of the rotating rod 503 is consistent with the internal dimension structure of the guiding groove 509. One end of the fixed cylinder 502 away from the hydraulic rod 501 is fixedly connected to a fixing piece 5010. A spring 5011 is fixedly connected to the edge of one side of the fixing piece 5010 connected to the fixed cylinder 502. One end of the spring 5011 away from the fixing piece 5010 is fixedly connected to an abutting ring 5012. Four balls 5013 are embedded on one side of the abutting ring 5012 away from the spring 5011. The four balls 5013 are all in contact with one side of the second moving ring 507. The inner diameters of the first moving ring 504, the second moving ring 507 and the abutting ring 5012 are all larger than the outer diameter of the fixed cylinder 502;The bottle cap to be hot stamped is placed on the outside of the inner support assembly 5, and then the hydraulic rod 501 is extended to push the rotating rod 503 to move along the guide groove 509. When the rotating rod 503 moves, it will synchronously drive the first moving ring 504 connected to it to move along the axial direction of the hydraulic rod 501 and gradually approach the fixed plate 5010. At this time, the active rod 505 on the first moving ring 504 will open the driven rod 506 in the direction away from the outer side of the fixed cylinder 502, so that the end of the driven rod 506 close to the active rod 505 contacts the inner wall of the bottle cap, thereby completing the inner support fixation of the bottle cap. At this point, the hot stamping mechanism 4 can be started to hot stamp a small pattern on the bottle cap. In this process, since the elastic force of the spring 5011 is greater than the force required to open the driven rod 506, the second moving ring 507 will not push the abutting ring 5012 to move toward the fixed plate 5010. If a long pattern needs to be hot stamped around the side of the bottle cap, The hydraulic rod 501 is started to extend continuously. Since the driven rod 506 is restricted by the inner wall of the bottle cap and cannot continue to expand, the hydraulic rod 501 will push the second moving ring 507 to squeeze the abutting ring 5012, so that the abutting ring 5012 moves toward the fixed plate 5010. At the same time, the rotating rod 503 will enter the spiral groove part of the guide groove 509 under the push of the hydraulic rod 501. The rotating rod 503 moves along the spiral groove, and when moving, the rotating rod 503 will rotate around the axis of the fixed cylinder 502. The rotating rod 503 drives the first moving ring 504 to rotate. The first moving ring 504 drives the active rod 505 and the driven rod 506 to rotate around the axis of the fixed cylinder 502, thereby driving the bottle cap fixed on the outside of the driven rod 506 to rotate, so as to stamp the long pattern on the side of the bottle cap. When the bottle cap moves, the hydraulic arm will also push the stamping mechanism 4 to move synchronously. ;

[0027] In this embodiment, Figure 1 and Figure 2As shown in the figure, the rotating assembly 2 includes a support shaft 201 rotatably connected to the middle of the top surface of the support table 1. The top end of the support shaft 201 is fixedly connected with a secondary gear 202. The top of the secondary gear 202 is fixedly connected with a rotating table 203. Four mounting plates 204 are arranged on the top of the rotating table 203. One side of each of the four mounting plates 204 close to the middle of the rotating table 203 is fixedly connected with a hydraulic rod 501 and a fixed cylinder 502. One side of the secondary gear 202 is meshed with a primary gear 205. The middle of the bottom surface of the primary gear 205 is fixedly connected with the output end of a servo motor 206. The servo motor 206 is fixedly connected to the top surface of the support table 1. The transmission ratio of the primary gear 205 to the secondary gear 202 is 1:4, and there are four inner support assemblies 5 evenly distributed on the mounting plates 204 of the rotating table 203; when one bottle cap is hot stamped, the servo motor 206 is started to drive the primary gear 205 at the output end to rotate one circle. The rotation of the primary gear 205 will drive the meshed secondary gear 202 to rotate around the support shaft 201. At this time, the rotating table 203 on the top of the secondary gear 202 also rotates accordingly. Because the transmission ratio of the primary gear 205 to the secondary gear 202 is 1:4, when the primary gear 205 rotates one circle, the secondary gear 202 will drive the rotating table 203 to rotate 90°, sending the next bottle cap to be hot stamped under the hot stamping mechanism 4, saving the time for waiting for blanking and loading, and improving the hot stamping efficiency.

[0028] The usage method and advantages of the present utility model: When the hot stamping machine capable of hot stamping the side of the bottle cap in all directions is in use, the working process is as follows:

[0029] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, firstly, the bottle cap to be hot stamped is sleeved on the outside of the inner support assembly 5, and then the hydraulic rod 501 is extended to push the rotating rod 503 to move along the guide groove 509. When the rotating rod 503 moves, it will synchronously drive the first moving ring 504 connected thereto to move along the axis direction of the hydraulic rod 501 and gradually approach the fixed plate 5010. At this time, the active rod 505 on the first moving ring 504 will open the driven rod 506 in the direction away from the outer side surface of the fixed cylinder 502, so that the end of the driven rod 506 close to the active rod 505 contacts the inner wall of the bottle cap, thereby completing the inner support fixation of the bottle cap. At this point, the hot stamping mechanism 4 can be started to stamp the bottle cap with a small pattern. In this process, since the elastic force of the spring 5011 is greater than the force required to open the driven rod 506, the second movable ring 507 will not push the abutting ring 5012 to move toward the fixed plate 5010. If a long pattern needs to be stamped around the side of the bottle cap, the hydraulic rod 501 is started to continue to extend. Since the driven rod 506 is restricted by the inner wall of the bottle cap and cannot continue to expand, the hydraulic rod 501 will push the second movable ring 507 to squeeze the abutting ring 5012, so that the abutting ring 5012 moves toward the fixed plate 5010. At the same time, Under the push of the hydraulic rod 501, the rotating rod 503 will enter the spiral groove part of the guide groove 509, and the rotating rod 503 will move along the spiral groove. When moving, the rotating rod 503 will rotate around the axis of the fixed cylinder 502, and the rotating rod 503 will drive the first moving ring 504 to rotate. The first moving ring 504 will drive the active rod 505 and the driven rod 506 to rotate around the axis of the fixed cylinder 502, thereby driving the bottle cap fixed on the outside of the driven rod 506 to rotate, so as to stamp the long pattern on the side of the bottle cap. While the bottle cap is moving, the hydraulic arm will also push the stamping mechanism 4 to synchronize When a bottle cap is stamped, the servo motor 206 starts to drive the main gear 205 at the output end to rotate one circle. The rotation of the main gear 205 will drive the sub-gear 202 meshing with it to rotate around the support shaft 201. At this time, the rotating table 203 on the top of the sub-gear 202 also rotates. Because the transmission ratio of the main gear 205 and the sub-gear 202 is 1:4, the main gear 205 rotates one circle, and the sub-gear 202 will drive the rotating table 203 to rotate 90°, and send the next bottle cap to be stamped to the bottom of the stamping mechanism 4, saving the time of waiting for unloading and loading, and improving the stamping efficiency.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
