The shearing mechanism is connected to the gantry, and the limiting mechanism is connected to the shearing mechanism and located above the scrap steel transport base. The scrap steel gantry shear with anti-deviation shearing mechanism provided by this utility model can prevent the scrap steel to be sheared from shifting during shearing, reduce the size difference between sheared scrap steel, and thus improve work efficiency.
[0004] The existing technology has the following problems:

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1-5 As shown, a double-sided shearing mechanism of a license plate scrapping and recycling machine includes a housing 1, a platform 2 fixedly connected to the lower part of the inner cavity of the housing 1, a lower blade holder 6 fixedly connected to the middle part of the upper part of the platform 2, and an upper blade holder mechanism 7 slidably connected to the middle part of the inner cavity of the housing 1.
[0027] The upper blade holder mechanism 7 includes an upper blade holder 71, which is slidably connected to the middle of the inner cavity of the housing 1. A cutting blade 73 is fixedly connected to the middle of the opposite side of the upper blade holder 71 and the lower blade holder 6. Two sliding rods 74 distributed front and back are slidably connected to the left and right sides of the upper blade holder 71. A pressure plate 77 is fixedly connected to the lower surface of the two sets of sliding rods 74. A limit plate 75 is fixedly connected to the upper surface of the two sets of sliding rods 74. A compression spring 76 is movably sleeved on the outer periphery of the sliding rod 74.
[0028] It should be noted that the housing 1, as the main frame of the entire double-sided shearing mechanism, provides the mounting base and protective space for the internal components. The platform 2 is used to place the license plate to be sheared. The lower blade holder 6 and the upper blade holder 71 work together to achieve double-sided shearing of the license plate. The upper blade holder 71 is the mounting base for the cutting blade 73. Driven by the hydraulic cylinder 4, the upper blade holder 71 moves up and down, driving the cutting blade 73 to complete the shearing action. The cutting blade 73 is the core component that actually performs the shearing operation. The cutting blade 73 is made of high-strength alloy steel and is precision ground to ensure the sharpness and accuracy of the shearing surface. The slide rod 74 is used to install the pressure plate 77 and the limiting plate 75. The sliding of the slide rod 74 allows the pressure plate 77 to press and fix the license plate before shearing. The pressure plate 77 is used to press the license plate before shearing to prevent displacement of the license plate during shearing and ensure shearing accuracy. The limiting plate 75 is used to limit the sliding range of the slide rod 74 to prevent the pressure plate 77 from excessively pressing down and damaging the license plate or equipment. The compression spring 76 provides elastic force to the pressure plate 77, enabling the pressure plate 77 to automatically reset after shearing, while also buffering the impact force during the shearing process.
[0029] like Figure 3 As shown, a hydraulic cylinder 4 is fixedly connected to the middle of the upper surface of the housing 1. The output end of the hydraulic cylinder 4 is fixedly connected to the middle of the upper surface of the upper tool holder 71. Limiting blocks 72 are fixedly connected to both the front and rear sides of the upper tool holder 71. The two limiting blocks 72 are slidably connected to the front and rear sides of the middle of the inner cavity of the housing 1, respectively.
[0030] It should be noted that the hydraulic cylinder 4 provides the power required for shearing, driving the upper cutter holder 71 to move up and down to complete the shearing action. The limit block 72 is used to limit the movement trajectory of the upper cutter holder 71, preventing it from deviating during the shearing process and ensuring shearing accuracy and equipment stability.
[0031] like Figure 3 As shown, infrared detection mechanisms 8 are fixedly connected to the left and right sides of the inner cavity of the box 1, temperature detection mechanism 9 is fixedly connected to the middle of the lower part of the pressure plate 77, and protective mechanisms 3 are movably connected to the left and right sides of the upper part of the box 1.
[0032] It should be noted that the infrared detection mechanism 8, by emitting and receiving infrared signals, can accurately determine whether the license plate is in place and whether the cutting is complete, providing feedback signals for the automated control of the equipment. The temperature detection mechanism 9 is used to detect whether there are people between the cutter holders to prevent operator injury.
[0033] like Figure 2 As shown, the protective mechanism 3 includes a take-up roller 31. Two take-up rollers 31 are rotatably connected to the left and right sides of the upper part of the housing 1, respectively. A protective net 32 is wound around the middle of the outer periphery of the take-up roller 31. A sliding plate 34 is fixedly connected to the lower part of the protective net 32. Two sliding plates 34 are slidably connected to the left and right sides of the housing 1.
[0034] It should be noted that the take-up roller 31 is used to take up and release the protective net 32, allowing the protective net 32 to be quickly unfolded or retracted when needed. The protective net 32 is used to protect the operating area during the shearing process, preventing metal fragments from flying and injuring people. The slide plate 34 is used to guide the unfolding and retraction of the protective net 32, ensuring its smooth movement.
[0035] like Figure 5 As shown, the front and rear ends of the outer periphery of the take-up roller 31 are rotatably connected to the cover 35. The lower surface of the cover 35 is fixedly connected to the upper surface of the box 1. The outer periphery of the front and rear ends of the take-up roller 31 is fixedly connected to the spring spring 33. The outer periphery of the spring spring 33 is fixedly connected to the inner cavity of the cover 35. The front and rear sides of the box 1 are movably connected to the drive mechanism 5.
[0036] It should be noted that the cover 35 provides installation space for the take-up roller 31, while protecting the take-up roller 31 and the spring 33 from the influence of the external environment. The spring 33 is used to provide rebound force for the take-up roller 31, so that the protective net 32 can automatically retract after shearing.
[0037] like Figure 2As shown, the drive mechanism 5 includes a motor 51. Two motors 51 are fixedly connected to the left side of the front and rear sides of the housing 1, respectively. A threaded rod 52 is fixedly connected to the output end of the motor 51. A connecting plate 53 is slidably connected to the outer periphery of the threaded rod 52. The opposite sides of the two connecting plates 53 are fixedly connected to the front and rear sides of the two slide plates 34, respectively. A support plate 54 is fixedly connected to the lower part of the front and rear sides of the housing 1. The threaded rod 52 is rotatably connected to the left side of the support plate 54.
[0038] It should be noted that motor 51 drives the threaded rod 52 to rotate. The rotational motion of motor 51 is converted into linear motion of connecting plate 53 via threaded rod 52, thereby controlling the unfolding and retraction of slide plate 34 and protective net 32. The sliding connection between threaded rod 52 and connecting plate 53 converts rotational motion into linear motion. Connecting plate 53 transmits the rotational motion of threaded rod 52 to slide plate 34, controlling the unfolding and retraction of protective net 32. Support plate 54 supports threaded rod 52 and limit rod 56, ensuring stable operation of drive mechanism 5.
[0039] like Figure 2 As shown, a limiting rod 56 is fixedly connected to the right side of the support plate 54, and a fixing block 55 is fixedly connected to the upper part of the limiting rod 56. The two fixing blocks 55 are fixedly connected to the front and rear sides of the right side of the box 1 respectively, and the right side of the connecting plate 53 is slidably connected to the outer periphery of the limiting rod 56.
[0040] It should be noted that the limiting rod 56 is used to restrict the movement trajectory of the connecting plate 53 and prevent it from deviating during movement. The fixing block 55 is used to fix the upper part of the limiting rod 56 and enhance the overall stability of the drive mechanism 5.
[0041] The working principle of this utility model is as follows: The operator places the license plate to be scrapped and destroyed on the platform 2. At this time, the infrared detection mechanisms 8 on the left and right sides of the middle of the inner cavity of the box 1 are activated, emitting infrared signals and detecting reflected signals. If the license plate is not accurately placed, the infrared detection mechanism 8 sends a feedback signal to the control system, and the equipment is in standby mode; only when the license plate is accurately positioned and the infrared detection mechanism 8 detects a normal signal, the equipment enters the startable state.
[0042] After receiving the arrival signal from the infrared detection mechanism 8, the control system sends a start command to the motor 51 of the drive mechanism 5. The motor 51 starts working, and its output end drives the threaded rod 52 to rotate. Since the threaded rod 52 is slidably connected to the connecting plate 53, and the right side of the connecting plate 53 is slidably connected to the limit rod 56, the rotational motion of the threaded rod 52 is converted into the linear motion of the connecting plate 53. The connecting plate 53 drives the slide plate 34, which is fixedly connected to it, to slide downwards along the left and right sides of the box body 1, thereby pulling the protective net 32 to unfold from the winding roller 31. The winding roller 31 begins to rotate under the pull of the protective net 32, and the spring 33 is stretched to store elastic potential energy. As the slide plate 34 continues to slide down, the protective net 32 is fully unfolded, forming a protective barrier on the left and right sides of the box body 1 to prevent metal fragments from flying and injuring people during the subsequent shearing process.
[0043] After the protective net 32 is fully deployed, the control system activates the hydraulic cylinder 4. The output end of the hydraulic cylinder 4 pushes the upper cutter holder 71 downward in the middle of the inner cavity of the housing 1. The limiting blocks 72 on the front and rear sides of the upper cutter holder 71 slide along the tracks on the front and rear sides of the middle of the inner cavity of the housing 1 to ensure that the movement trajectory of the upper cutter holder 71 is stable and does not deviate. As the upper cutter holder 71 descends, the pressure plate 77, which is fixedly connected to the lower surface of the sliding rods 74 on both sides, first contacts the license plate. Under the pressure of the pressure plate 77, the sliding rods 74 slide upward relative to the upper cutter holder 71, the compression spring 76 is compressed, generating elastic force, so that the pressure plate 77 presses the license plate tightly to prevent the license plate from shifting during the cutting process. When the upper cutter holder 71 continues to descend to the appropriate position, the cutting blades 73, which are fixedly connected to the middle of the opposite side of the upper cutter holder 71 and the lower cutter holder 6, move closer to each other and cut the license plate on both sides. During the cutting process, the temperature detection mechanism 9, which is fixedly connected to the middle of the lower part of the pressure plate 77, monitors the temperature of the area between the cutter holders in real time. If an abnormal temperature rise is detected, it may indicate a equipment malfunction or abnormal situation. The temperature detection mechanism 9 will send a signal to the control system, which will immediately stop the operation of the hydraulic cylinder 4 and the motor 51 to prevent equipment damage and safety accidents.
[0044] After shearing is completed, the output end of hydraulic cylinder 4 retracts, driving the upper cutter holder 71 to move upward. At this time, the compressed spring 76 recovers its elastic deformation, pushing the slide rod 74 and pressure plate 77 to reset downward. After the upper cutter holder 71 returns to its initial position, the control system sends a reverse command to motor 51. Motor 51 drives the threaded rod 52 to rotate in the opposite direction, and the connecting plate 53 slides upward under the action of the threaded rod 52 and the limit rod 56, driving the slide plate 34 to move upward. The winding roller 31 automatically rotates in the opposite direction under the elastic restoring force of the spring spring 33, rewinding the protective net 32 onto the winding roller 31, completing the reset work of the entire shearing process. The equipment enters standby mode, waiting for the next operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
