Description

Technical Field

[0001] This utility model relates to the field of license plate hot stamping equipment, and in particular to a highly stable ultra-wide license plate hot stamping roller support reinforcement device. Background Technology

[0002] Hot stamping rollers are key components for hot stamping license plates, and their stability directly affects the stamping effect. Existing technologies, such as the Chinese utility model patent with publication number CN223187218U, disclose a manual hot stamping mechanism, including a worktable, an unwinding roller, a rewinding roller, and a hot stamping assembly. The hot stamping assembly is located between the unwinding roller and the rewinding roller, both of which are rotatably connected to the worktable. The worktable also includes a conveyor belt. A first conveyor roller and a second conveyor roller are rotatably connected to both ends of the worktable, and the conveyor belt is tensioned by the first and second conveyor rollers. A support plate is fixedly connected to the worktable, supporting the conveyor belt and located between the conveyor belt and the hot stamping assembly.

[0003] However, with the expansion of license plate application scenarios, the demand for ultra-wide license plates is increasing. For hot stamping of ultra-wide license plates, it is necessary to use hot stamping rollers with correspondingly longer roller surfaces to ensure coverage of the entire hot stamping area. However, when using the existing support structure, the rigidity and load-bearing capacity of the single-plate support structure are insufficient to meet the support requirements of the long-surface hot stamping roller after the roller surface length is increased, due to the single-plate support design. Specifically, the long-surface hot stamping roller will generate greater torque due to its own weight and hot stamping pressure during operation, making the single-plate support structure prone to deflection and deformation. This can lead to roller axis misalignment or vibration, resulting in uneven pressure distribution during hot stamping and failing to meet the high precision and high stability requirements of ultra-wide license plate hot stamping. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable reinforcement device for the support of ultra-wide license plate hot stamping rollers. This invention utilizes a double-plate support structure to support the hot stamping roller, effectively improving the stability of the support and meeting the requirements for ultra-wide license plate hot stamping.

[0005] The technical solution of this utility model is as follows: a high-stability ultra-wide license plate hot stamping roller support reinforcement device, including a roller support frame, a main plate and a secondary plate on the roller support frame, a hot stamping motor support on one side of the secondary plate, a drive motor on the hot stamping motor support, and a rotating shaft connected to the output end of the drive motor; a first bearing seat is installed on one side of the main plate, and a second bearing seat passes through the main plate and the secondary plate, with one end of the second bearing seat tightly attached to one end of the first bearing seat; the rotating shaft passes through the first bearing seat and the second bearing seat, and a hot stamping roller assembly is connected to one end of the rotating shaft via a key.

[0006] In the aforementioned high-stability ultra-wide license plate hot stamping roller support reinforcement device, the main board and the sub-board are spaced a certain distance apart.

[0007] In the aforementioned high-stability ultra-wide license plate hot stamping roller support reinforcement device, the inner end of the hot stamping motor support has a vertical surface, which is connected to the bottom side of the sub-plate via screws.

[0008] In the aforementioned high-stability ultra-wide license plate hot stamping roller support reinforcement device, the hot stamping roller group includes a roller body disposed at one end of a rotating shaft, and a balancing component located inside the roller body is provided on the end face of the rotating shaft.

[0009] In the aforementioned high-stability ultra-wide license plate hot stamping roller support reinforcement device, the balancing component includes a positioning pin disposed on the end face of the rotating shaft, a radial block disposed on the positioning pin, an adjustment groove disposed on the radial block, and a movable and adjustable balancing rod disposed on the adjustment groove.

[0010] In the aforementioned high-stability ultra-wide license plate hot stamping roller support reinforcement device, a positioning ring is provided on the rotating shaft. One side of the positioning ring is in contact with the end face of the first bearing seat, and the other side of the positioning ring is in contact with the center end face of the roller body.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses a main plate and a secondary plate on the roller support frame to form a double-plate support structure. Compared with the single-plate support plate in the prior art, bearing seats are set in the double plates, and the rotating shaft passes through the bearing seats, which effectively enhances the support rigidity and overall load-bearing capacity of the hot stamping roller assembly. The first bearing seat and the second bearing seat are in close contact, which increases the support area for the rotating shaft, effectively offsetting the torque generated by the long roller surface hot stamping roller due to its own weight and hot stamping pressure, avoiding the deflection deformation problem that is prone to occur in single-plate support, ensuring that the axis of the hot stamping roller always remains stable, and ensuring the uniformity of ultra-wide license plates during hot stamping.

[0012] 2. The balance component on the end face of the rotating shaft in the hot stamping roller assembly can be flexibly adjusted according to the operating state of the long roller hot stamping roller. By moving the balance rod along the adjustment groove to different positions, it can effectively counteract the centrifugal force deviation when the roller rotates at high speed, reduce bearing wear and roller shaking caused by imbalance, and significantly extend the service life of core components such as hot stamping roller and bearing seat.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] Example: A high-stability ultra-wide license plate hot stamping roller support reinforcement device, including a roller support frame 1, as shown in the attached figure. Figure 1 As shown, a main plate 2 and a secondary plate 3 are mounted on the roller support frame 1. The main plate and the secondary plate are connected to the roller support frame by bolts. A hot stamping motor support 4 is mounted on one side of the secondary plate 3. The inner end of the hot stamping motor support 4 has a vertical surface 10, as shown in the attached figure. Figure 3 As shown, the vertical surface 10 is connected to the bottom side of the auxiliary plate 3 via screws. This connection method forms a rigid fixed installation with bottom support, which can transmit the vibration generated by the drive motor during operation to the double-plate support system for dispersion and dissipation, avoiding vibration transmitted to the hot stamping roller assembly through the rotating shaft and causing operational vibration. This structural design ensures the motor's secure installation and reduces the interference of vibration on the hot stamping process, further improving the smoothness of the hot stamping roller rotation. The hot stamping motor support 4 is equipped with a drive motor 5, and the bottom support of the drive motor is connected to the hot stamping motor support via bolts. The output end of the drive motor 5 is connected to the rotating shaft 6, as shown in the attached figure. Figure 2 As shown; a first bearing seat 7 is installed on one side of the main board 2, and a second bearing seat 8 is installed inside the main board 2 and the sub-board 3. One end of the second bearing seat 8 is in close contact with one end of the first bearing seat 7, as shown in the attached figure. Figure 4As shown; the rotating shaft 6 passes through the first bearing seat 7 and the second bearing seat 8. Both bearing seats have flanges, which are connected to their respective plates via bolts. The rotating shaft 6 has a positioning ring 17, one side of which is in contact with the end face of the first bearing seat 7, and the other side is in contact with the center end face of the roller body 11. The positioning ring mainly serves to axially position the roller body. During installation, the center end face of the roller body will be tightly against the positioning ring. One end of the rotating shaft 6 is connected to a hot stamping roller group 9 via a key. The main plate 2 and the sub-plate 3 are spaced a certain distance apart, ranging from 15 mm to 17 mm. This reasonable spacing allows the two plates to form a distributed load-bearing structure, evenly distributing the load to the connection point between the two plates and the support frame, reducing the stress on individual bolts, preventing component deformation or loosening due to excessive local stress, and extending the overall service life of the device.

[0017] The hot stamping roller assembly 9 includes a roller body 11 disposed at one end of a rotating shaft 6, and a balancing component 12 located inside the roller body 11 is provided on the end face of the rotating shaft 6, as shown in the attached figure. Figure 5 As shown; the balancing component 12 includes a positioning pin 13 disposed on the end face of the rotating shaft 6. The positioning pin is connected to the end face of the rotating shaft by threads. A radial block 14 is fixed on the positioning pin 13. The radial block 14 has an adjustment groove 15. A movable and adjustable balance rod 16 is installed in the adjustment groove 15. The balance rod has a fixing nut. After the position of the balance rod is determined, the fixing nut is tightened to fix the balance rod. The balancing component can flexibly adjust the balance according to the running state of the hot stamping roller. By moving the balance rod along the adjustment groove to different positions, the centrifugal force deviation when the roller rotates at high speed is effectively offset, the bearing wear and roller shaking caused by imbalance are reduced, and the service life of core components such as the hot stamping roller and bearing seat is significantly extended.

[0018] The working principle of this utility model is as follows: A main plate 2 and a secondary plate 3 are installed on the roller support frame 1. The main plate 2 and the secondary plate 3 are spaced apart by a certain distance, forming a double-plate support structure. The second bearing seat 8 is synchronously inserted into the preset holes of the main plate 2 and the secondary plate 3, and one end of it is tightly fitted with the first bearing seat 7 independently installed on the outside of the main plate 2. The rotating shaft 6 is inserted into the first bearing seat 7 and the second bearing seat 8, which improves the support rigidity and anti-deformation ability. Then, the hot stamping motor support 4 is connected to the bottom side of the secondary plate 3 through the vertical part 10, and the drive motor 5 outputs torque. Its output end is connected to the rotating shaft 6. The rotating shaft 6 drives the hot stamping roller group 9 to rotate to realize the hot stamping of license plates.
