Description

Technical Field

[0001] The utility model relates to the field of license plate hot stamping, in particular to a manual hot stamping mechanism. Background Art

[0002] Chinese Patent Authorization Announcement No. CN201863480U discloses a hot stamping machine specifically for license plates, designed to automatically and continuously stamp license plates. The machine's structure primarily includes a workbench, a hot stamping unit, a hot stamping film delivery unit, and a heating unit. The hot stamping unit comprises a rotatable lower steel roller, a lifting frame fixed to the workbench, and an upper rubber roller mounted on the lifting frame and rotatably engaged with the lower steel roller. The hot stamping film delivery unit includes a film support mechanism and a film collection mechanism located on both sides of the upper rubber roller and fixed to the workbench, for supplying and retrieving the hot stamping film. The heating unit is located above the upper rubber roller.

[0003] The patent discloses a hot stamping machine for license plates. A heating unit heats the upper rubber roller, and the rolling action between the upper rubber roller and the lower steel roller transfers and secures the hot stamping film to the license plate surface, achieving hot stamping. This design aims to improve hot stamping efficiency through heated rolling and achieve automated, continuous operation.

[0004] However, during use, it was discovered that although the equipment could automatically complete the hot stamping process, the stamped license plate remained located between the upper and lower steel rollers, directly adjacent to the upper roller. Due to the high surface temperature of the newly stamped license plate, the operator still needed to manually remove the license plate from the workbench after the equipment completed rolling. This manual removal method not only reduced overall work efficiency but also posed a potential risk of burns to the operator's hands from the hot license plate, creating certain inconveniences. Therefore, the existing technology still needs to improve the post-stamping license plate removal process. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a manual hot stamping mechanism to facilitate the export of the license plate from the workbench.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a manual hot stamping mechanism, including a workbench, a unwinding roller, a winding roller and a hot stamping assembly, the hot stamping assembly is located between the unwinding roller and the winding roller, the unwinding roller and the winding roller are both rotatably connected to the workbench, and also includes a conveyor belt, the two ends of the workbench are respectively rotatably connected to the first conveyor roller and the second conveyor roller, the conveyor belt is tensioned by the first conveyor roller and the second conveyor roller, and a support plate is fixedly connected to the workbench, the support plate supports the conveyor belt and is located between the conveyor belt and the hot stamping assembly.

[0007] To implement the above technical solution, an operator places the license plate to be stamped on a conveyor belt. Driven by first and second conveyor rollers, the conveyor belt moves smoothly to a position beneath the stamping assembly. From this position, the stamping assembly stamps the license plate while the conveyor belt is supported by a support plate. After stamping is complete, the conveyor belt continues to move forward, automatically transporting the hot, stamped license plate away from the stamping area to a safe location. This eliminates the manual removal of the hot license plate, a step previously required in the prior art. This significantly reduces the risk of burns to the operator's hands, improves operational safety and convenience, and overcomes the unsafe manual removal process found in prior art. The stamping film is placed on a reel, which rotates to unwind the film. After passing between the stamping assembly and the license plate, the stamping assembly completes the stamping process, and the waste film is wound onto a reel for recycling.

[0008] As a preferred solution of the present utility model, a power motor is connected to the workbench, a first connecting wheel is connected to the power shaft of the power motor, a second connecting wheel is connected to the second conveying roller, a connecting belt is provided between the first connecting wheel and the second connecting wheel, and the connecting belt is tensioned by the first connecting wheel and the second connecting wheel.

[0009] To implement the above technical solution, the power motor on the workbench transmits the driving force to the second connecting wheel connected to the second conveyor roller through the first connecting wheel connected to its power shaft with the help of a connecting belt. This causes the second conveyor roller to rotate and drives the conveyor belt to move. The moving conveyor belt is used to carry the license plates that need to be hot stamped, send them under the hot stamping assembly for processing, and automatically move the license plates out of the hot stamping area after the hot stamping is completed. It provides power to transport the license plates in and out of the hot stamping area, realizing the automation or semi-automation of the license plate processing process. Most importantly, the automatic transfer function of the conveyor belt completely avoids the operator from directly manually touching the high-temperature license plates that have just been hot stamped, fundamentally eliminating the risk of burns, significantly improving the safety and convenience of operation, and improving overall production efficiency.

[0010] As a preferred solution of the present invention, the winding roller is connected to a driven wheel, the power shaft is connected to a driving wheel, a transmission belt is provided between the driven wheel and the driving wheel, and the transmission belt is tensioned through the driven wheel and the driving wheel.

[0011] To implement the above technical solution, the power shaft of the power motor is connected to and drives the first connecting wheel and the driving wheel at the same time. The first connecting wheel is connected to the second connecting wheel of the second conveyor roller via a connecting belt drive, thereby driving the conveyor belt to move to carry the license plate in and out of the hot stamping area. At the same time, the driving wheel on the power shaft is connected to the driven wheel of the take-up roller via a transmission belt drive, so that the take-up roller rotates synchronously to reel in the used hot stamping film. This coordinated movement of automatic license plate transportation and synchronous reeling of waste film achieves a high degree of automation in the hot stamping process, completely avoiding the risk of burns caused by manual contact with high-temperature license plates for removal and placement, and significantly improving the safety and convenience of operation; at the same time, it ensures the timely and neat recovery of waste film, ensures the smooth operation of the equipment and the cleanliness of the site, thereby comprehensively improving the overall operating efficiency and system reliability.

[0012] As a preferred solution of the present invention, a tensioning pulley is rotatably connected to the side wall of the workbench, and the transmission belt is tensioned by the driven pulley, the driving pulley and the tensioning pulley.

[0013] To implement the above technical solution, the tensioning wheel arranged on the side wall of the workbench cooperates with the driven wheel of the winding roller and the driving wheel of the power shaft to tension the transmission belt; this effectively prevents the transmission belt from slipping during the transmission process and ensures the stability and accuracy of the winding roller drive.

[0014] As a preferred solution of the present invention, a first guide roller, a second guide roller and a third guide roller are connected to the workbench, the first guide roller is located below the unwinding roller and above the conveyor belt, the second guide roller is close to the hot stamping assembly and above the conveyor belt, and the third guide roller is located below the winding roller and above the conveyor belt.

[0015] Implementing the above technical solution makes the conduction of the hot stamping film smoother.

[0016] As a preferred solution of the present invention, the hot stamping assembly includes a support frame, a drive motor, a rubber roller, a thermal insulation cover and a heating tube. One end of the support frame is hinged to the workbench, and the other end of the support frame is connected to the workbench through an elastic structure. The rubber roller is rotatably connected to the support frame, the drive motor is connected to the support frame and drives the rubber roller to rotate, the thermal insulation cover is hinged to the support frame, and when the thermal insulation cover is covered on the support frame, the rubber roller is located inside the thermal insulation cover, and the heating tube is fixed to the inner wall of the thermal insulation cover.

[0017] To implement this technical solution, when the support frame is pressed downward, the drive motor rotates the rubber roller, generating heat from the heating tube. A thermal cover, located on the outside of the rubber roller, effectively traps heat and reduces dissipation. As the roller rotates, it presses the hot stamping film onto the license plate surface on the conveyor belt. This provides stable and energy-efficient heated roller hot stamping. The thermal cover ensures a more uniform and constant temperature across the hot stamping area. Combined with the rotation of the drive roller and the conveyance of the license plate, this system enables continuous, high-quality automated hot stamping, while also helping to reduce energy consumption and improve equipment performance and the stability of the hot stamping results.

[0018] As a preferred solution of the present invention, the outer wall of the heat-insulating cover is fixedly connected to a protective mesh cover, and a handle is connected to the outer wall of the heat-insulating cover, and the handle passes through the protective mesh cover.

[0019] The protective mesh provides a layer of physical isolation, effectively preventing operators from accidentally touching the hot surface during use or maintenance, which could cause burns. The handle also provides a safe and convenient grip for operators, making it easier and more reliable to open or adjust the insulation cover.

[0020] As a preferred solution of the present invention, a limit plate is fixedly connected to the workbench, the limit plate is close to the unwinding roller, the thermal insulation cover moves away from the rubber roller and the limit plate supports the protective mesh cover.

[0021] To implement the above technical solution, when the heat shield on the hot stamping assembly moves away from the rubber roller, the stop plate contacts and supports the protective mesh on the outer wall of the heat shield. This provides a safe and convenient way to open and secure the heat shield, allowing the rubber roller to dissipate heat quickly and prevent damage due to high temperatures.

[0022] As a preferred solution of the present invention, the elastic structure includes an elastic part, a pressure rod, a connecting plate, and a driving rod. The two ends of the elastic part are respectively connected to the support frame and the workbench. The pressure rod is slidably connected to the workbench and is used to push the support frame to move toward the conveyor belt. The driving rod is L-shaped, and one end of the driving rod is hinged to the workbench and is located above the pressure rod. One end of the connecting plate is hinged to the pressure rod, and the other end of the connecting plate is hinged to the bending part of the driving rod.

[0023] To implement this technical solution, when the operator manually tilts the drive lever downward, the connecting plate drives the pressure rod to slide, which in turn pushes the support frame downward, pressing the rubber roller against the license plate on the conveyor belt to complete the hot stamping. When the operator manually tilts the drive lever upward, the pressure rod separates from the support frame. At this point, relying solely on the elastic force of the elastic member, the support frame moves upward quickly and unimpeded, lifting the rubber roller away from the license plate. This ensures that the rubber roller is immediately lifted off the license plate surface after hot stamping is completed, effectively preventing sticking, stringing, and damage to the license plate and the hot stamping effect, and simplifying the return operation.

[0024] As a preferred solution of the present invention, a temperature sensor is fixedly connected to the support frame, a controller is connected to the workbench, and the temperature sensor, power motor, drive motor, and heating tube are all electrically connected to the controller.

[0025] Implementing this technical solution enables automated monitoring and control of the core process. The controller receives real-time temperature information from the temperature sensor and precisely regulates the operating state of the heating tube to ensure and maintain the required stable hot stamping temperature. Simultaneously, the controller automatically controls the start / stop and operating states of the power and drive motors, thereby achieving automated or semi-automated coordination of key processes such as heating, rubber roller rotation, and license plate conveyance. This significantly improves the consistency, efficiency, and reliability of hot stamping operations, ensuring consistent hot stamping quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0035] A manual hot stamping mechanism includes a workbench 1, a payout roller 2, a take-up roller 3, and a hot stamping assembly 21. The hot stamping assembly 21 is located between the payout roller 2 and the take-up roller 3. Both the payout roller 2 and the take-up roller 3 are rotatably connected to the workbench 1. A hot stamping film 4 is wound around the payout roller 2. After the hot stamping film 4 passes through the hot stamping assembly 21 and completes the hot stamping of the license plate 100, the waste film is wound around the take-up roller 3.

[0036] A first conveyor roller 5 and a second conveyor roller 6 are rotatably connected to both ends of the workbench 1. The first and second conveyor rollers 5 and 6 are arranged horizontally, and the axes of the first and second conveyor rollers 5 and 6 are arranged parallel to each other. A conveyor belt 7 is tensioned by the first and second conveyor rollers 5 and 6. A support plate 8 is fixedly connected to the workbench 1, supporting the conveyor belt 7 and being located between the conveyor belt 7 and the hot stamping assembly 21.

[0037] A power motor 9 is fixedly connected to the inner wall of the workbench 1. A power shaft 10 of the power motor 9 extends through the side wall of the workbench 1 and is fixedly connected to a first connecting wheel 11. The axis of the first connecting wheel 11 is coaxial with the axis of the power shaft 10. A second connecting wheel 12 is fixedly connected to the end of the second conveyor roller 6. The axis of the second conveyor roller 6 is coaxial with the axis of the second connecting wheel 12. A connecting belt 13 is provided between the first connecting wheel 11 and the second connecting wheel 12, and the connecting belt 13 is tensioned by the first connecting wheel 11 and the second connecting wheel 12.

[0038] A driven wheel 14 is fixedly connected to the end of the winding roller 3, and the axis of the driven wheel 14 is coaxially arranged with the axis of the winding roller 3. A driving wheel 15 is fixedly connected to the power shaft 10, and a transmission belt 16 is provided between the driven wheel 14 and the driving wheel 15.

[0039] A tensioning wheel 17 is rotatably connected to the side wall of the workbench 1, and the axis of the tensioning wheel 17 is arranged parallel to the axis of the driven wheel 14. The transmission belt 16 is tensioned by the driven wheel 14, the driving wheel 15 and the tensioning wheel 17.

[0040] The first connecting wheel 11 and the second connecting wheel 12 are gears, and the connecting belt 13 is a toothed belt. The conveyor belt 7 and the transmission belt 16 are belts.

[0041] A first guide roller 18, a second guide roller 19, and a third guide roller 20 are fixedly connected to the workbench 1. The first guide roller 18 is located below the unwinding roller 2 and above the conveyor belt 7. The second guide roller 19 is close to the hot stamping assembly 21 and above the conveyor belt 7. The third guide roller 20 is located below the winding roller 3 and above the conveyor belt 7.

[0042] The hot stamping film 4 is unwound from the unwinding roller 2, passes around the first guide roller 18 and the second guide roller 19, passes under the hot stamping assembly 21, then passes around the third guide roller 20, and finally is wound around the winding roller 3. The axes of the first guide roller 18, the second guide roller 19, and the third guide roller 20 are all arranged parallel to the axis of the first conveyor roller 5.

[0043] The hot stamping assembly 21 includes a support frame 22, a drive motor 23, a rubber roller 24, a heat shield 25, and a heating tube 26. One end of the support frame 22 is hinged to the workbench 1, and the other end is connected to the workbench 1 via an elastic structure 30. The rubber roller 24 is rotatably connected to the support frame 22 and is located in the middle of the support frame 22. The drive motor 23 is fixedly connected to the outer wall of the support frame 22 and drives the rubber roller 24 to rotate. The axis of the rubber roller 24 is arranged horizontally and parallel to the axis of the first conveyor roller 5.

[0044] The heat-insulating cover 25 is hingedly connected to the support frame 22. When the heat-insulating cover 25 is placed on the support frame 22, the rubber roller 24 is located inside the heat-insulating cover 25, and the heating tube 26 is fixed to the inner wall of the heat-insulating cover 25. A limit plate 37 is fixedly connected to the side wall of the heat-insulating cover 25. When the heat-insulating cover 25 is placed on the support frame 22, the limit plate 37 contacts the upper surface of the support frame 22, thereby maintaining the position of the heat-insulating cover 25.

[0045] A protective mesh cover 27 is fixedly connected to the outer wall of the heat-insulating cover 25 . A handle 28 is connected to the outer wall of the heat-insulating cover 25 , and the handle 28 passes through the protective mesh cover 27 .

[0046] A limit plate 29 is fixedly connected to the workbench 1 and is located between the unwinding roller 2 and the support frame 22. The heat-insulating cover 25 moves away from the rubber roller 24 and enables the limit plate 29 to support the protective mesh cover 27.

[0047] The elastic structure 30 comprises an elastic member 31, a pressure rod 32, a connecting plate 33, and a driving rod 34. The ends of the elastic member 31 are connected to the support frame 22 and the workbench 1, respectively. The elastic member 31 is a tension spring. The pressure rod 32 is vertically positioned and slidably connected to the workbench 1 to push the support frame 22 toward the conveyor belt 7.

[0048] The driving rod 34 is L-shaped, and one end of the driving rod 34 is hinged on the workbench 1 and is located above the pressure rod 32. One end of the connecting plate 33 is hinged to the pressure rod 32, and the other end of the connecting plate 33 is hinged to the bend of the driving rod 34.

[0049] There is friction between the driving rod 34 and the workbench 1, there is friction between the driving rod 34 and the connecting plate 33, and there is friction between the connecting plate 33 and the pressing rod 32. The positioning of the driving rod 34 is achieved by the action of friction.

[0050] The operator manually tilts the drive rod 34 downward, causing it to flip the connecting plate 33. The connecting plate 33 pushes the pressure rod 32 downward, which contacts the upper surface of the support frame 22 and pushes the support frame 22 downward, causing the rubber roller 24 to press against the license plate 100 through the hot stamping film 4. When the operator tilts the drive rod 34 upward, the pressure rod 32 is separated from the support frame 22. The elastic force of the elastic member 31 causes the support frame 22 to move upward, and the rubber roller 24 to move away from the conveyor belt 7.

[0051] A temperature sensor 35 is fixedly connected to the end of the support frame 22, and a controller 36 is connected to the workbench 1. The temperature sensor 35, the power motor 9, the drive motor 23, and the heating tube 26 are all electrically connected to the controller 36. The controller 36 is a PLC controller 36.

[0052] First, the operator starts the equipment. The PLC controller 36 receives the signal from the temperature sensor 35 and controls the operation of the heating tube 26, heating the rubber roller 24 in the heat-insulating cover 25 to the set hot stamping temperature. At the same time, the operator places the license plate 100 to be hot stamped on the conveyor belt 7. The PLC controller 36 drives the power motor 9, which drives the second conveyor roller 6 through the connecting belt 13 to move the conveyor belt 7, conveying the license plate 100 to the bottom of the hot stamping assembly 21. During the hot stamping process, the power motor 9 also drives the take-up roller 3 to rotate synchronously via the transmission belt 16, pulling the hot stamping film 4 from the unwinding roller 2. The film is then guided by the guide roller so that the film 4 passes under the hot stamping assembly 21 together with the license plate 100. The waste film generated after hot stamping is continuously wound up by the take-up roller 3.

[0053] When the end of the license plate 100 approaches the bottom of the rubber roller 24, the operator manually tilts down the drive lever 34, causing the pressure rod 32 to contact and push the support frame 22 downward. This causes the rubber roller 24 on the support frame 22 to tightly roll the hot stamping film 4 onto the surface of the license plate 100. After the hot stamping is complete, the operator manually tilts up the drive lever 34, causing the pressure rod 32 to automatically separate from the support frame 22. The support frame 22, relying solely on the elastic force of the elastic member 31, quickly pivots upward and lifts, moving the rubber roller 24 away from the license plate 100 and the conveyor belt 7.

[0054] Subsequently, the conveyor belt 7 continues to move to move the stamped license plate 100 out of the stamping area.

[0055] When maintenance or heat dissipation is required, the operator can manually flip up the heat-insulating cover 25 along the hinge point, and the limiting plate 29 supports the protective mesh cover 27.

[0056] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
