Description

Technical Field

[0001] This utility model relates to the field of waste metal recycling technology, specifically a shearing device for waste metal recycling. Background Technology

[0002] With increasing global resource scarcity and growing environmental awareness, the recycling of scrap metal has become an important method of resource regeneration. Scrap metal recycling not only effectively reduces resource waste and production costs but also minimizes environmental pollution. However, scrap metal is often irregularly shaped, bulky, and hard, posing significant challenges to recycling. To improve the efficiency and safety of scrap metal recycling, shearing technology is widely used in the initial processing stage. Shearing technology is a process that uses mechanical force to cut metal materials into small pieces or specific shapes, facilitating subsequent transportation, smelting, and reprocessing. Using shearing technology to process scrap metal has significant advantages. First, shearing technology effectively reduces the volume of scrap metal, facilitating transportation and storage, and making the metal materials easier to classify and process, greatly improving the overall efficiency of the recycling process. Second, scrap metal often has high hardness and strength, making direct processing difficult. Shearing technology can cut the metal into smaller pieces, reducing the difficulty and energy consumption of subsequent processing and improving smelting efficiency.

[0003] Shearing technology is applicable to a variety of metal materials, including steel, aluminum, and copper. Different types of shearing equipment and blades can be selected and adjusted according to the characteristics of the metal materials, exhibiting strong adaptability and flexibility.

[0004] Currently, the automation level of scrap metal shearing and recycling operations is not high. In the scrap metal shearing process, manual processing of the sheared metal blocks is still required. Since scrap metal has sharp edges and irregular shapes during processing, it is easy to cause accidents that cause workers to be cut, which poses a safety hazard. Utility Model Content

[0005] The purpose of this invention is to provide a shearing device for recycling waste metals, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shearing device for recycling waste metal, comprising a first conveyor belt and a second conveyor belt, and further comprising a pressing mechanism and a slicing mechanism disposed at both ends of the first conveyor belt, the second conveyor belt being disposed below the slicing mechanism, and a material box being disposed above the second conveyor belt, wherein a material metering mechanism is disposed inside the material box.

[0007] Preferably, the tablet pressing mechanism includes a pressure roller support, a pressure roller motor, and two pressure rollers rotatably connected to the pressure roller support. The pressure roller motor is fixedly connected to the pressure roller support via a motor mounting base, and the output shaft of the pressure roller motor is connected to a pressure roller via a coupling.

[0008] Based on the above technical features, the tableting mechanism crushes irregularly structured scrap metal, increasing the density and uniformity of the scrap metal, which facilitates subsequent shearing operations, thereby improving the efficiency and quality of the entire recycling process.

[0009] Preferably, the slicing mechanism includes a gantry frame fixedly connected to a conveyor belt, a cutting blade mounted on the gantry frame, a pressure seat, a discharge plate, a cutting seat, and a hydraulic cylinder. Two guide columns are fixed between the gantry frame and the cutting seat. The pressure seat and a lifting platform are slidably connected to the two guide columns. The hydraulic cylinder is fixed to the upper end of the gantry frame, and the piston rod of the hydraulic cylinder is fixed to the upper end of the lifting platform. The cutting blade is fixed to the lower end of the lifting platform. Multiple limiting rods are fixed to the upper end of the pressure seat, and the limiting rods pass through the lifting platform. Furthermore, the top tube of the limiting rod is fixedly connected to a limiting block, and a compression spring is sleeved on the limiting rod, with the compression spring located between the lifting platform and the pressing seat; the cutting seat is fixedly connected to the gantry frame and the conveyor belt, the inner end of the unloading plate is rotatably connected to the inside of the gantry frame, and the lower ends of the unloading plate are respectively rotatably connected to the piston rods of an electric telescopic cylinder, with the two electric telescopic cylinders respectively rotatably connected to both sides of the gantry frame; there is a gap between the unloading plate and the cutting seat, and the cutting blade is located above the gap between the unloading plate and the cutting seat.

[0010] Based on the above technical features, this slicing mechanism can perform efficient slicing operations on metal sheets; the compression spring sleeved on the limit rod is located between the lifting platform and the pressure seat, playing a buffering and stabilizing role, ensuring that the metal sheet can be firmly pressed down during the cutting process, avoiding the impact of vibration on the cutting effect; the inner end of the feeding plate is rotatably connected to the gantry frame, and the lower two sides are rotatably connected by the piston rods of the electric telescopic cylinders respectively. The electric telescopic cylinders are fixed on both sides of the gantry frame, which can control the tilt angle of the feeding plate, ensuring that the cut metal sheet falls smoothly into the second conveyor belt.

[0011] Preferably, the material box is located below the feeding plate, and the material metering mechanism includes a movable seat, a conductive sheet, and two electrical contact points. The movable seat is located inside the material box, and multiple damping springs are provided between the movable seat and the bottom of the material box. A limit stop is fixed to the inner side wall of the material box, and the limit stop is located below the movable seat. The conductive sheet is fixed to the lower end of the movable seat by an insulating seat. The two electrical contact points are fixed to the bottom of the material box by an insulating seat, and the two electrical contact points are located below the conductive sheet. The two electrical contact points are electrically connected to an external controller.

[0012] Based on the above technical features, the material box's loading amount can be accurately monitored and controlled by setting two electrical contact points and conductive plates, preventing overload. When the material reaches the predetermined weight, the conductive plate contacts the electrical contact point, feeding back a signal to the external controller to control the operation of conveyor belt two; this achieves automated material transfer and metering, improving the automation level and operating efficiency of the equipment; the damping spring can effectively prevent large deformation caused by the metal plate falling into the metal box, providing effective support for the movable seat and preventing the electrical contact point and conductive plate from contacting too early, which could lead to insufficient material loading in the material box.

It effectively reduces manual intervention, eliminates the need for manual feeding by staff, thereby greatly reducing the probability of accidents, minimizing safety hazards during operation, and improving the safety of the working environment.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3The present invention provides an embodiment of a shearing device for recycling scrap metal, comprising a first conveyor belt 1 and a second conveyor belt 2, and further comprising a pressing mechanism and a slicing mechanism disposed at both ends of the first conveyor belt 1. The second conveyor belt 2 is disposed below the slicing mechanism, and a material box 3 is disposed above the second conveyor belt 2. The material box 3 is provided with a material metering mechanism, which can realize continuous material transmission and accurate metering, thereby improving the efficiency and accuracy of scrap metal recycling.

[0022] Please refer to the attached diagram in the instruction manual. Figure 3 The tableting mechanism includes a pressure roller support 4, a pressure roller motor 5, and two pressure rollers 6 rotatably connected to the pressure roller support 4. The pressure roller motor 5 is fixedly connected to the pressure roller support 4 through a motor mounting seat 7. The output shaft of the pressure roller motor 5 is connected to one of the pressure rollers 6 through a coupling. By driving the pressure roller to rotate through the pressure roller motor, the metal material on the conveyor belt can be effectively compacted, ensuring the flatness and stability of the material and improving the accuracy of subsequent slicing.

[0023] Please refer to the attached diagram in the instruction manual. Figure 3The slicing mechanism includes a gantry frame 8 fixedly connected to conveyor belt 1, a cutting blade 9 mounted on the gantry frame 8, a pressure seat 10, a feeding plate 11, a cutting seat 12, and a hydraulic cylinder 17. Two guide columns 13 are fixed between the gantry frame 8 and the cutting seat 12. The pressure seat 10 and the lifting platform 14 are slidably connected to the two guide columns 13. The guide columns 13 ensure the smooth sliding of the lifting platform 14 and the pressure seat 10, avoiding deviation during the cutting process. The hydraulic cylinder 17 is fixed to the upper end of the gantry frame 8, and the piston rod of the hydraulic cylinder 17 is fixed to the upper end of the lifting platform 14. The cutting blade 9 is fixed to the lower end of the lifting platform 14. Driven by the hydraulic cylinder 17, the lifting platform 14 moves up and down, thereby driving the cutting blade 9 fixed at its lower end to achieve vertical cutting of the metal. Multiple limiting rods 15 are fixed at the upper end of the pressure seat 10. The limiting rods 15 pass through the lifting platform 14, and the top tube of the limiting rod 15 is fixedly connected to the limiting block 25. A compression spring 16 is sleeved on the limiting rod 15. The compression spring 16 is located between the lifting platform 14 and the pressure seat 10. The design of the limiting rod 15 and the compression spring 16 provides a certain elastic clamping force during cutting, ensuring that the pressure seat 10 fixes the metal sheet during the cutting process and prevents the metal sheet from shifting. The cutting seat 12 is fixedly connected to the gantry frame 8 and the conveyor belt 1. The inner end of the unloading plate 11 is rotatably connected to the gantry frame 8. The lower ends of the unloading plate 11 are rotatably connected to the piston rods of an electric telescopic cylinder 18 on both sides. The two electric telescopic cylinders 18 are rotatably connected to both sides of the gantry frame 8. By extending and retracting the electric telescopic cylinders 18, the angle and position of the unloading plate 11 are adjusted, so that the cut metal sheets can fall accurately into the material box 3, avoiding material scattering and waste, and improving production efficiency. At the same time, the application of the electric telescopic cylinders 18 makes the adjustment of the unloading plate 11 more flexible and precise, and can adapt to metal sheets of different sizes and shapes. There is a gap between the unloading plate 11 and the cutting seat 12, and the cutting blade 9 is located above the gap between the unloading plate 11 and the cutting seat 12.

[0024] Please refer to the attached diagram in the instruction manual. Figure 3The material box 3 is located below the feeding plate 11. The material metering mechanism includes a movable seat 19, a conductive sheet 20, and two electrical contact points 21. The movable seat 19 is located inside the material box 3. Multiple damping springs 22 are provided between the movable seat 19 and the bottom of the material box 3. The application of damping springs 22 can not only ensure the smooth movement of the movable seat 19, but also effectively absorb the impact force when the material is dropped, protecting the stability and durability of the metering mechanism. A limit stop 23 is fixed to the inner wall of the material bin 3. The limit stop 23 is located below the movable seat 19. The limit stop 23 prevents the movable seat 19 from moving excessively, ensuring the reliability of the system operation. The conductive sheet 20 is fixed to the lower end of the movable seat 19 through the insulating seat 24. The two electrical contact points 21 are fixed to the bottom of the material bin 3 through the insulating seat 24. The two electrical contact points 21 are located below the conductive sheet 20 and are electrically connected to an external controller. The external controller controls the motor of the second conveyor belt 2. When the scrap metal sheet is cut and falls into the material bin 3, the movable seat 19 moves downward under the weight of the metal sheet, compressing the damping spring 22. After moving to a certain position, the conductive sheet 20 contacts the two electrical contact points 21, thereby forming a circuit and generating an electrical signal. This electrical signal is transmitted to the external controller. After receiving the signal, the controller starts the motor of the second conveyor belt 2, making the second conveyor belt 2 work to transport the metered metal sheet to the next processing step.

[0025] Working principle

[0026] This utility model relates to a shearing device for recycling scrap metal, used for shearing scrap metal.

[0027] In use, the pressure roller motor 5, electric telescopic cylinder 18, and electrical contact point 21 are electrically connected to an external power source and controller. The controller can be a conventionally known component such as a computer. The hydraulic cylinder 17 is connected to an external hydraulic pump, oil tank, and controller for operation.

[0028] The working process of this shearing device for scrap metal recycling is as follows:

[0029] The scrap metal passes between the two pressure rollers 6 of the pressing mechanism. The pressure roller motor 5 starts and drives the pressure rollers 6 to rotate through the coupling. The pressure rollers 6, supported by the pressure roller bracket 4, perform the pressing process on the metal.

[0030] The flattened metal continues to move along conveyor belt 1 and enters the slicing mechanism. The hydraulic cylinder 17 in the slicing mechanism is activated, and the piston rod pushes the lifting platform 14 downward. The cutting blade 9, which is fixed at the lower end of the lifting platform 14, moves downward accordingly. The cutting blade 9 passes through the gap between the feed plate 11 and the cutting seat 12 to cut the metal sheet. The pressure seat 10 ensures that the metal sheet remains stable during the cutting process and does not move due to the cutting force through the action of the limiting rod 15 and the compression spring 16.

[0031] The electric telescopic cylinder 18 adjusts the position of the feeding plate 11 to control the falling direction and angle of the material, ensuring that the cut metal sheet falls accurately into the material box 3.

[0032] Material box 3 is equipped with a material metering mechanism. The movable seat 19 moves down under the weight of the metal sheet, compressing the damping spring 22. When the movable seat 19 moves down to a certain position, the conductive sheet 20 contacts the two electrical contact points 21, forming an electrical signal. The electrical signal is transmitted to the external controller. The external controller controls the motor of the second conveyor belt 2 to start according to the received signal. The second conveyor belt 2 starts working and transports the metal sheet in the material box 3 to the next processing step or a designated position.
