A channel for hardware parts to pass through is left between the two limiting plates 5. The channel is aligned with the feeding port 16 on the feeding plate 6. When the hardware parts are conveyed to the position of the limiting plate 5 along the conveyor belt 3, the hardware parts move towards the center of the conveyor belt 3 due to the blocking and guiding effect of the limiting plate 5, correcting the position of the hardware parts, so that the hardware parts can be smoothly conveyed through the feeding port 16 to the two feeding plates 6.

[0022] A support plate 7 is fixedly connected to the outer wall of the feed plate 6 located on the rear side. A turntable 8 is rotatably connected to the upper surface of the support plate 7.

[0024] A sliding hole 13 is formed in the middle section of the transmission plate 12, a movable push plate 14 with a bottom abutting the material conveying structure is slidingly connected between the two feeding plates 6, the second transmission rod 15 is fixedly connected to the upper surface of the middle section of the movable push plate 14, the top ends of the first transmission rod 10 and the second transmission rod 15 penetrate the transmission plate 12 through the sliding hole 13 and can slide along the length direction of the sliding hole 13, and when the first transmission rod 10 is rotated to the right side of the rotating disc 8, one end of the movable push plate 14 in the inner cavity of the feeding plate 6 is synchronously slid to the right side of the feeding port 16, so that the hardware can be driven by the conveyor belt 3 to enter the gap between the two feeding plates 6 through the feeding port 16.

[0025] It should be noted that the continuous feeding device for vacuum coating of hardware is used, the hardware is placed on the conveyor belt 3, then the first motor 4 is started to drive the conveyor belt 3 to rotate clockwise, the hardware is transmitted to the feeding plate 6, when the hardware is conveyed to the position of the limiting plate 5, the hardware is guided by the limiting plate 5 to move to the middle position of the conveyor belt 3 and is aligned with the feeding port 16 formed in the feeding plate 6, as the conveyor belt 3 continues to transmit, the hardware can be conveyed to the gap between the two feeding plates 6 along the conveyor belt 3, at this time, the second motor 9 is started to drive the rotating disc 8 to rotate, since the first transmission rod 10 is eccentrically installed on the upper surface of the rotating disc 8, when the rotating disc 8 rotates, the first transmission rod 10 can drive the movable push plate 14 to reciprocate in the gap between the two limiting plates 5 by cooperating with the transmission plate 12, the sliding hole 13 and the second transmission rod 15, when the first transmission rod 10 is rotated to the left side of the rotating disc 8, the hardware in the gap enters through the feeding port 16 and is pushed out from the left side of the support 1 for feeding, at the same time, the hardware on the subsequent conveyor belt 3 is blocked from entering the gap, when the first transmission rod 10 is rotated to the right side of the rotating disc 8, one end of the movable push plate 14 in the inner cavity of the feeding plate 6 is synchronously slid to the right side of the feeding port 16, the feeding port 16 is opened, the next hardware enters the gap through the feeding port 16, and the above process is repeated to realize uniform feeding of the hardware, the device has a simple structure, does not need to use a complex sensor structure to realize uniform feeding of the hardware, greatly saves the production cost and is convenient for users to use.
