Description

Motor vehicle license plate destruction device Technical Field

[0001] This utility model relates to the field of license plate destruction technology, and in particular to a motor vehicle license plate destruction device. Background Technology

[0002] As the legal certificate authorizing a vehicle to drive on the road, vehicle license plates are issued and regulated uniformly by traffic management departments. Their legal status is crucial, therefore strict supervision is required throughout their entire lifecycle, from production and use to recycling. The license plate management process not only requires the destruction of substandard plates generated during the production stage, but also the timely destruction of old license plates recovered from vehicle transfers and deregistrations. This is to prevent obsolete license plates from entering society and causing traffic management hazards, and to ensure the standardization and safety of road traffic order.

[0003] Currently, the disposal of most used license plates in China still relies on manual cutting. This process involves manually shearing the metal plates. Because license plates typically have reinforcing ribs stamped along their edges, the shearing process requires operators to apply significant force continuously, resulting in high labor intensity and low efficiency. While some scenarios utilize electric cutting tools to increase processing speed, these devices pose noise pollution and safety risks, and require highly skilled operators. Although a small number of automated disposal devices exist on the market, the recycled license plates are generally bent, deformed, or damaged due to long-term use and dismantling processes. Existing equipment has stringent requirements for the regularity of the license plate's shape and struggles to handle complex-shaped used plates, leading to significant compatibility issues.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0044] Figure 1 shows a front axle view of the vehicle license plate destruction device provided in an exemplary embodiment of the present invention, with the protective cover and hood concealed. Figure 2 shows a rear axle view of the vehicle license plate destruction device provided in an exemplary embodiment of the present invention, with the protective cover and hood concealed. The vehicle license plate destruction device includes: a feeding mechanism 2, which is installed on the top of the cabinet 1 for conveying vehicle license plates to be destroyed; and a shearing mechanism 3, which is installed on the top of the cabinet 1 and includes a shearing frame 31 located on one side of the feeding mechanism 2, an electric cylinder 32 installed on the shearing frame 31, and an extension mechanism installed on the electric cylinder 32. The upper cutter 33 on the retractable end and the lower cutter 34 installed at the conveying tail end of the feeding mechanism 2 are positioned correspondingly; and the discharge port 4 is located below the shearing frame 31 and is used to guide the destroyed vehicle license plates to the external waste bin; wherein, a license plate pressing seat 35 is also installed on the retractable end of the electric cylinder 32. The license plate pressing seat 35 is located on the side of the upper cutter 33 close to the feeding mechanism 2. The license plate pressing seat 35 is elastically connected to the retractable end of the electric cylinder 32 through a spring 36. When the spring 36 is in an uncompressed state, the bottom end of the license plate pressing seat 35 is lower than the bottom end of the upper cutter 33.

[0045] In this embodiment, the feeding mechanism 2 forms a standardized license plate input channel through the top-mounted guide groove and conveying guide, ensuring that the license plates to be destroyed are accurately positioned in a fixed posture (face up, edges aligned), providing a stable input foundation for the subsequent shearing process. The shearing frame 31 of the shearing mechanism 3 serves as a rigid support, ensuring the transmission accuracy of the vertical driving force of the electric cylinder 32; the electric cylinder 32 drives the upper cutter 33 downward, forming a shearing pair with the lower cutter 34 fixed at the end of the feed, using the shearing force generated by the misaligned blades to destroy the license plate structure. The key design lies in the elastic linkage between the license plate pressure seat 35 and the spring 36. When not compressed, the bottom of the pressure seat is lower than the cutter, ensuring that the pressure seat presses firmly on the surface of the license plate before shearing. The pressure is gradually increased through spring buffering to prevent the license plate from shifting or deforming during shearing, and the complete breakage of the license plate is achieved in conjunction with the bite of the cutter.

[0046] It should be noted that the cutting edge of the upper cutter 33 has an angle of 9° with the horizontal direction, thereby reducing the thrust required by the electric cylinder 32 when cutting the license plate.

[0047] In detail, please refer to Figures 1 and 2. The feeding mechanism 2 includes: a feeding guide 21, which is installed on the top of the cabinet 1, and has a paddle guide 22 in its middle, in which a conveying paddle 23 is movably disposed; and a drive assembly 24, which is installed on the top of the cabinet 1 and located in the overhead space at the bottom of the feeding guide 21, for driving the conveying paddle 23 to move along the paddle guide 22; wherein the paddle guide 22 is arranged in the direction of the shearing mechanism 3.

[0048] Furthermore, referring to Figures 1 and 3, the drive assembly 24 includes: a servo motor 241, which is mounted on the top of the cabinet 1 via a first bearing seat 242, and a drive wheel 243 is mounted on its power output end; and a ball screw 244, which is mounted on the top of the cabinet 1 via a second bearing seat 245, and a driven wheel 246 is mounted on one end of the ball screw 244. The drive wheel 243 and the driven wheel 246 are connected by a synchronous belt 247. The nut pair 2441 of the ball screw 244 is connected to the conveyor plate 23.

[0049] In this embodiment, the guide groove 22 defines the linear motion trajectory of the conveying guide 23, and, in conjunction with the limiting of the short side of the license plate on both sides, ensures that the license plate is conveyed to the shearing mechanism 3 in a constant posture. In the drive assembly 24, the servo motor 241 is fixed to the top of the cabinet 1 through the first bearing seat 242, and its drive wheel 243 drives the driven wheel 246 through the synchronous belt 247, transmitting the rotational power of the servo motor 241 to the ball screw 244; the ball screw 244 is stably supported by the second bearing seat 245, and its nut pair 2441 is rigidly connected to the conveying guide 23, converting the rotational motion of the ball screw 244 into the linear motion of the conveying guide 23.

[0050] Furthermore, referring to Figure 2, an inclined discharge plate 5 is installed at the discharge port 4 to facilitate the export of the vehicle license plates after destruction. Referring to Figure 1, a camera 6 is also installed on the shearing frame 31. The camera 6 is located on the side of the shearing frame 31 near the feeding mechanism 2 and is used to collect information on the vehicle license plates to be destroyed. A starting baffle 25 is also provided at the beginning of the feeding guide trough 21, and the starting end of the conveying plate 23 is located inside the starting baffle 25.

[0051] In this embodiment, the inclined discharge plate 5 of the discharge port 4 uses gravity guidance to allow the cut license plate waste to slide quickly into the external waste bin along the inclined surface, avoiding waste accumulation that could affect equipment operation. This also simplifies the manual cleaning process and improves destruction efficiency. A camera 6 on the shearing frame 31 is located on one side of the feeding mechanism 2. It can collect license plate information (such as characters and numbers) in real time before the license plates are conveyed to the shearing station. Image recognition technology enables traceability of the destruction process, meeting regulatory compliance requirements. The starting baffle 25 at the beginning of the feeding guide trough 21 cooperates with the conveying plate 23 to provide a reset reference point for the conveying plate 23. When the conveying plate 23 retracts to the inside of the starting baffle 25, it ensures that each loaded license plate is accurately positioned at the same initial position, guaranteeing consistency in subsequent conveying distance control and shearing accuracy.

[0052] It is worth mentioning that, as shown in Figure 4, a protective cover 26 is also installed on the feed guide chute 21. The protective cover 26 is open at both ends along the conveying direction of the feeding mechanism 2. As shown in Figure 5, a cover 7 is also installed on the top of the cabinet 1 to enclose the feeding mechanism 2 and the shearing mechanism 3. The front side of the cover 7 has a feed inlet 9. A control panel 8 is installed on the cover 7 for operating the feeding mechanism 2 and the shearing mechanism 3.

[0053] In this embodiment, the protective cover 26 covers the feed guide 21, and the openings at both ends do not affect the license plate conveying, which can prevent personnel from contacting moving parts and ensure operational safety; the machine cover 7 encloses the feeding and shearing mechanism, and the front feed port facilitates feeding, and its dustproof and splashproof design optimizes the working environment; the control panel 8 is integrated into the machine cover to realize centralized control of the feeding and shearing mechanism, and improve the convenience of human-machine interaction and the controllability of equipment operation.

[0054] It is understood that the feeding mechanism 2, the shearing mechanism 3, the camera 6, and the control panel 8 are all electrically connected to the cabinet 1. The cabinet 1 integrates at least a power module and a control module to enable the coordinated operation of the components.

[0055] In this embodiment, the power supply module in the cabinet 1 provides unified power supply to ensure the stable operation of each component; the control module coordinates the sequence of actions such as conveying, collecting, and cutting according to a preset program, and integrates the information from the camera 6 to achieve process traceability; the control panel 8 serves as an interactive interface, converting operation commands into electrical signals and transmitting them to the control module, thereby achieving automated and precise collaboration of the destruction process through modular integration.

[0056] For example, the power module integrates components such as switching power supplies and UPS to provide a stable power supply and anti-interference protection for various parts of the equipment, ensuring the energy foundation for system operation. The control module, with a PLC as its core, works in conjunction with motion controllers, industrial computers, etc., to achieve precise control of equipment action logic, data processing, and automated process management.

[0057] Next, the working principle of a motor vehicle license plate destruction device involved in the embodiments of this utility model will be explained.

[0058] Step 1: First, the conveyor plate 23 is reset to the inside of the starting baffle 25, and then the vehicle license plate to be destroyed is placed into the feeding guide trough 21. When placing it, ensure that the front of the vehicle license plate is facing up, its long side is in close contact with the conveyor plate 23, and its short side is close to the two sides of the feeding guide trough 21, so as to ensure that the license plate is placed in an accurate position.

[0059] Step 2: After the vehicle license plate is properly placed, the servo motor 241 starts to run, and drives the ball screw 244 to rotate through the synchronous belt 247; the nut pair 2441 of the ball screw 244 then drives the conveyor plate 23 to move along the plate guide groove 22, thereby pushing the vehicle license plate forward in the direction of the shearing mechanism 3.

[0060] Step 3: When the vehicle license plate is conveyed to the area below the camera 6, the servo motor 241 stops rotating. At this time, the camera 6 begins to collect information about the vehicle license plate to be destroyed to ensure the traceability of the license plate destruction process. After the information collection is completed, the servo motor 241 restarts and continues to push the vehicle license plate to the area below the shearing frame 31.

[0061] Step 4: After the conveyor pawl 23 pushes the vehicle license plate out of the lower cutter 34 a certain distance, the servo motor 241 stops working; the electric cylinder 32 drives the license plate pressing seat 35 and the lower cutter 34 to extend and press down. Since the bottom of the license plate pressing seat 35 is lower than the bottom of the upper cutter 33 when the spring 36 is in an uncompressed state, the license plate pressing seat 35 will first contact and press the vehicle license plate. As the spring 36 is gradually compressed, the pressure continues to increase, and the upper cutter 33 moves towards the lower cutter 34 to cut the vehicle license plate until the license plate is completely cut off. The cut vehicle license plate slides down into the external waste bin through the material drop plate 5 of the material drop port 4.

[0062] Step 5: The conveying lever 23 is reset to the inside of the starting baffle 25. At this point, the vehicle license plate destruction device has completed the destruction process for the current vehicle license plate.

[0063] As a supplementary explanation, as shown in Figure 6, in order to ensure that all characters are incomplete after the license plate is destroyed, the cutting method is different for different types of license plates. If the vehicle license plate has a single line of characters, the cutting mechanism can cut along the single line of characters in one cut; if it has a double line of characters, after cutting one line of characters, the conveyor plate will push the vehicle license plate a certain distance to cut the second line of characters.

[0064] In summary, this technical solution includes a feeding mechanism installed at the top of the cabinet for conveying vehicle license plates to be destroyed; a shearing mechanism also installed at the top of the cabinet, comprising a shearing frame located on one side of the feeding mechanism, an electric cylinder mounted on the shearing frame, an upper cutter mounted on the telescopic end of the electric cylinder, and a lower cutter mounted on the conveying tail end of the feeding mechanism, with the upper and lower cutters corresponding to each other; and a discharge port located below the shearing frame for guiding the destroyed vehicle license plates to an external waste bin. A license plate pressure seat is also installed on the telescopic end of the electric cylinder, located on the side of the upper cutter near the feeding mechanism. The license plate pressure seat is elastically connected to the telescopic end of the electric cylinder via a spring; when the spring is uncompressed, the bottom of the license plate pressure seat is lower than the bottom of the upper cutter. This design improves the efficiency of license plate destruction, is compatible with the shearing and destruction of various types of deformed, damaged, or otherwise poorly shaped vehicle metal license plates, has a wide range of applications, is easy to maintain, and operates with low noise.
