[0029] 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.
[0030] Please see Figures 1-6 This utility model provides a technical solution: a bending and stabilizing feeding mechanism, including an upper base 1, a conveyor belt 2, a motor 3, a protrusion 4, a side baffle 5, a sliding block 6, a fixed rod 7, a telescopic rod 8, a spring 9, a connecting plate 10, a pressure plate 11, a lower base 12, a lower support rod 13, an upper support rod 14, and a cylinder 15.
[0031] A conveyor belt 2 is mounted on the upper surface of the upper base 1 via a bracket. The drive shaft of the conveyor belt 2 is fixedly connected to the output end of the motor 3. The motor 3 is fixedly mounted on the mounting bracket surface of the conveyor belt 2. The surface of the conveyor belt 2 is provided with rectangular protrusions 4, which are trapezoidal in structure. A height adjustment structure is provided below the upper base 1. The height adjustment structure uses a cylinder 15 to adjust the height of the upper base 1 to adapt to different bending machines. The height adjustment structure includes a lower base 12, which is located below the upper base 1. A lower support rod 13 is fixedly mounted on the surface of the lower base 12. An upper support rod 14 is slidably passed through the upper surface of the lower support rod 13. The upper end of the upper support rod 14 is fixedly connected to the lower surface of the upper base 1. The lower support rod 13 and the upper support rod 14 are arranged in a rectangle in 4 sets. A cylinder 15 is fixedly mounted on the upper surface of the lower base 12, and the output end of the cylinder 15 is fixedly connected to the lower surface of the upper base 1.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, when using this device to feed materials into a bending machine, the height of the device is adjusted according to the different models of bending machines. The cylinder 15 is started, and its output pushes the upper base 1 to move vertically up and down. The upper support rod 14 slides within the lower support rod 13, extending or shortening until the upper base 1 reaches a suitable height, ensuring precise alignment between the feeding mechanism and the bending machine's feed inlet. The raw material is placed on the surface of the conveyor belt 2. The motor 3 is started, driving the conveyor belt 2 to start and transporting the raw material across its surface. The trapezoidal protrusions 4 on the surface of the conveyor belt 2 increase the friction between the raw material and the conveyor belt 2 surface, ensuring the stability of the raw material transport.
[0033] A shielding structure is provided on both sides of the conveyor belt 2. The shielding structure limits the feeding process of the raw materials through the side baffles 5. The shielding structure includes the side baffles 5, which are fixedly installed on the front surface of the upper base 1. A square through hole is provided through the surface of the side baffles 5. A sliding block 6 is installed inside the square through hole on the surface of the side baffles 5. The cross-section of the sliding block 6 is a hollow square frame structure. A fixing rod 7 is provided through the surface of the sliding block 6. The fixing rod 7 is a threaded rod structure. The lower end of the fixing rod 7 is rotatably connected to the bottom of the inner surface of the sliding block 6. The outer surface of the fixing rod 7 is sleeved on the upper surface of the sliding block 6. The fixing rod 7 is threadedly connected to the upper surface of the side baffles 5. A telescopic mechanism is fixedly installed on the lower surface of the sliding block 6. The lower end of the telescopic rod 8 is fixed to the inner wall of the square through hole on the surface of the side baffle 5. A spring 9 is provided on the outer surface of the telescopic rod 8. One end of the spring 9 is fixed to the surface of the sliding block 6, and the other end of the spring 9 is fixed to the inner wall of the square through hole on the surface of the side baffle 5. Two identical sets of shielding structures are provided. The two sets of shielding structures are symmetrically installed on both sides of the conveyor belt 2. A pressing structure is provided between the two sets of shielding structures. The pressing structure achieves vertical positioning of the raw material through the pressure plate 11. The pressing structure includes a connecting plate 10. The two ends of the connecting plate 10 are respectively fixed to the surface of the sliding block 6 on both sides. The pressure plate 11 is fixedly installed on the lower surface of the connecting plate 10 through the bracket. The pressure plate 11 is set parallel to the surface of the conveyor belt 2.
[0034] like Figure 4 , Figure 5 and Figure 6 As shown, during the movement of the raw material on the surface of the conveyor belt 2, the height of the pressure plate 11 is adjusted according to the thickness of the raw material. Based on the thickness of the raw material, the fixed rod 7 is rotated, causing it to move vertically on the surface of the side baffle 5. The lower end of the fixed rod 7 drives the sliding block 6 to slide vertically on the surface of the side baffle 5. Simultaneously, the lower surface of the sliding block 6 drives the telescopic rod 8 to extend and retract synchronously, and the spring 9 to compress or extend synchronously. The sliding block 6, under the action of the fixed rod 7, adjusts its height to accommodate raw materials of different thicknesses. The spring 9 below the sliding block 6 can also dampen the vibration of the sliding block 6. The movement of the sliding block 6 synchronously drives the connecting plate 10 and the pressure plate 11 to rise and fall, maintaining appropriate pressure between the pressure plate 11 and the surface of the raw material. The pressure plate 11 prevents the raw material from warping due to vibration during transport. At the same time, the side baffles 5 on both sides limit the horizontal deviation of the raw material, ensuring that the raw material is transported along the central path of the conveyor belt 2.
[0035] Working principle: When using this bending and stabilizing feeding mechanism, the motor 3 drives the conveyor belt 2 to run. The protrusions 4 on the surface of the conveyor belt 2 can increase the friction between the raw material and the conveyor belt 2, so that the raw material is transported stably and slips during the conveying process. The side baffles 5 on both sides form a horizontal limiting channel to prevent the raw material from deviating. The height of the sliding block 6 on the side baffle 5 can be adjusted by the fixed rod 7. The sliding block 6 drives the pressure plate 11 to rise and fall through the connecting plate 10, so that the pressure plate 11 lightly presses the surface of the raw material to prevent the raw material from warping due to vibration. At the same time, it can adapt to raw materials of different thicknesses. The cylinder 15 can push the upper base 1 to realize the overall height adjustment, adapt to the worktable height of different bending machines, and increase the overall practicality.
