A middle fixed box 15 is fixedly connected to the top of the loader 1 and located between the two limit members 3.

Two clamping blocks 19 are fixedly connected at equal intervals on the outside of the transmission belt 2 18. The rotation of the transmission roller 2 17 can drive the transmission belt 2 18 to rotate, thereby driving the feeding operation of the plate. The setting of the clamping block 19 can not only play an important limiting role on the plate, but also push the plate into the loader 1.

[0034] Reference Figure 1 A monitoring mechanism is provided inside the slot plates 14, and the monitoring mechanism includes infrared receivers 20 fixedly installed inside the slot plates 14 at equal distances. An infrared transmitter 21 is fixedly installed on the outside of one of the limit members 3, and a controller 2 is fixedly installed on the outside of the feeder 1. When the transmission belt 13 drives the multiple slot plates 14 to rotate, the infrared transmitter 21 will emit infrared rays to the infrared receiver 20, and the infrared receiver 20 will transmit the information to the controller 2 after receiving the infrared rays, and control the feeding mechanism to operate through the controller 2, so that the plate can achieve the purpose of accurate feeding.

[0039] Working principle: First, when the plate needs to be loaded, the plate to be loaded is placed between the two limit members 3, and then the servo motor 12 is started, thereby driving the screw 8 to rotate, and then driving the two threaded blocks 10 to move towards or in opposite directions, thereby adjusting the distance between the two U-shaped plates 4 to adapt to the production of plates of different sizes;

[0040] When the distance between the two U-shaped plates 4 is adjusted, the servo motor 15 can be started by the controller 2. The rotation of the transmission roller 16 can drive the transmission belt 13 to rotate, thereby driving the multiple slot plates 14 to rotate. When the transmission belt 13 drives the multiple slot plates 14 to rotate, the infrared transmitter 21 will emit infrared rays to the infrared receiver 20, and the infrared receiver 20 will transmit the information to the controller 2 after receiving the infrared rays, and control the servo motor 3 16 to start through the controller 2, and push the plate into the loader 1, so that the plate can achieve the purpose of accurate feeding, and then the bottom plate can be loaded to a high place to cooperate with the next process for production.
