The feeding port 110 is used for feeding materials, the discharging port 120 is used for discharging materials, the flow guide assembly is used for guiding the flow of materials, the movable rod 230 can slide relative to the fixed seat 210, the spring 220 abuts against the movable rod 230, and the flow guide plate 240 is fixedly installed on the movable rod 230. When the material of the keyhole machine is conveyed, the material enters the feeding cavity 100 through the feeding port 110 and impacts on the flow guide plate 240, the flow guide plate 240 guides the flow of the material, and at the same time, the flow guide plate 240 is impacted to move the movable rod 230 towards the spring 220, so that the spring 220 is compressed to generate a restoring force to offset the impact force, thereby reducing the impact force on the flow guide plate 240, and further improving the service life of the flow guide plate 240.

[0022] Specifically, the rubber gasket 250 is detachably connected with the flow guide plate 240, and the rubber gasket 250 is located at the end of the flow guide plate 240 away from the movable rod 230. The rubber gasket 250 is arranged at the end of the flow guide plate 240 close to the feeding port 110, and when the material enters the feeding cavity 100 from the feeding port 110, the rubber gasket 250 is in contact with the material. Since the rubber gasket 250 is elastic, the flow guide plate 240 can be protected, and the rubber gasket 250 is easy to replace, further improving the service life of the flow guide plate 240.

[0023] The screen 260 is fixedly connected with the feeding cavity 100, and the screen 260 is located at the feeding port 110. The screen 260 can screen the size of the material to prevent the material with a large size from entering the feeding cavity 100 and blocking the feeding cavity 100.

When the rubber gasket 250 needs to be replaced, the L-shaped side frame 410 is pulled outward, so that the L-shaped stopper 420 is away from the rubber gasket 250, the rubber gasket 250 can be taken off from the flow guide plate 240, a new rubber gasket 250 is installed on the flow guide plate 240, the L-shaped stopper 420 is loosened, the L-shaped stopper 420 is reset under the action of the tension spring 320, the L-shaped stopper 420 shields the rubber gasket 250, and then the rubber gasket 250 is fixed on the flow guide plate 240.

[0027] When the feeding mechanism of the lock eye machine is used to convey the material, the material enters the feeding cavity 100 through the feeding port 110 and impacts on the flow guide plate 240, the flow guide plate 240 guides the material, and at the same time, the flow guide plate 240 is impacted to move the movable rod 230 to the direction close to the spring 220, so that the spring 220 is compressed to generate a restoring force to offset the impact force, thereby reducing the impact force on the flow guide plate 240, and the service life of the flow guide plate 240 is improved.
