[0023] Specifically, a transmission device 7 is provided, which is used to synchronously drive the turntable 42 to rotate in the forward direction when the conveying plate 5 moves forward. The end of the second connecting rod 72 is rotatably connected to the eccentric part of the turntable 42, and the end of the fourth connecting rod 74 is fixedly connected to the lower surface of the conveying plate 5 and the upper surface of the first connecting rod 71, so that when the first connecting rod 71 slides, the fourth connecting rod 74 can pull and drive the conveying plate 5 to slide and feed materials. During the feeding process, the second connecting rod 72 synchronously drives the turntable 42 to rotate, and the material is bent. This allows the feeding and bending operations to be realized with only one power source.

[0024] The transmission device 7 is used to synchronously drive the end of the storage plate 6 to move upward and tilt when the conveyor plate 5 moves back. When the bending ends and the conveyor plate 5 moves back, the third link 73 can squeeze and drive one end of the storage plate 6 to tilt upward. This allows the material to move upward under the action of the storage plate 6 when it needs to be fed, so that the material can be taken out without bending over.

[0025] The transmission device 7 includes a first connecting rod 71 that is slidably connected to the base 1.

[0026] Specifically, the conveyor plate 5 slides forward, and the first link 71 slides through the third link 73, which then drives the second link 72 to support the turntable 42, causing the turntable 42 to rotate and achieve the bending function. The conveyor plate 5 moves back, and the first link 71 moves back accordingly. The third link 73 drives the end of the storage plate 6 to move upward and tilt up, so that the storage plate 6 can move the material upward, making it easier to pick up the material.

[0027] The upper surface of the conveying platform 2 has a cavity 21 that extends through its lower surface. The conveying plate 5 is slidably disposed in the cavity 21.

The electric telescopic rod drives the material conveying plate 5 to slide back and forth. The cooperation between the third T-shaped block 51 and the third T-shaped groove 22 realizes the stable sliding of the material conveying plate 5.

[0029] The end of the conveying plate 5 is provided with a plug hole, and the upper surface of the conveying platform 2 near the tail end is fixedly installed with a guide tube 23. The fixing ring 41 is fixedly connected to the conveying platform 2 through the connecting bracket 43.

[0030] Specifically, the tail end of the material is inserted into the insertion hole, which enables the conveyor plate 5 to slide forward, driving the material forward, and the guide tube 23 supports the middle part of the material.

[0031] The inner wall of the fixed ring 41 is provided with a T-shaped annular groove 411. A T-shaped ring block 421 is fixedly connected to the periphery of the turntable 42. An annular plate 422 is fixedly connected to the side of the turntable 42. The diameter of the annular plate 422 is smaller than the diameter of the turntable 42. An annular groove 423 is provided on the periphery of the annular plate 422. A limit rod 44 is also fixedly connected to the side of the turntable 42.

[0032] Specifically, with the cooperation of the T-shaped annular groove 411 and the T-shaped annular block 421, the turntable 42 rotates stably within the fixed ring 41. The material is stuck in the annular groove 423 on its periphery. With the cooperation of the limiting rod 44, the material is bent as the turntable 42 rotates.

[0033] The storage plate 6 is inclined, and a second T-shaped block 61 is provided between the bottom end of the storage plate 6 and the base 1. The second T-shaped block 61 is slidably connected to the base 1 and rotatably connected to the storage plate 6. A second T-shaped groove 12 matching the second T-shaped block 61 is provided on the surface of the base 1.

[0034] Specifically, the cooperation of the second T-shaped block 61 and the second T-shaped groove 12 supports the storage plate 6, allowing it to slide stably on the base 1, preventing end vibration due to the sliding of the storage plate 6, which would cause the material to tip over and fall.
