Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-8 , the present invention provides two technical solutions, specifically including the following embodiments:

[0031] Embodiment 1: Refer to Figures 1-3 , an input device for teaching management, including a body 1. A camera module 2 is fixedly installed on the top surface of the body 1 for performing portrait input. The camera module 2 is an existing device and is controlled based on the storage control module 3. A storage control module 3 is installed inside the body 1. A placing rack 4 is fixedly installed inside the body 1. The placing rack 4 contains the paper 13 to be input. An electric telescopic rod 11 is fixedly installed inside the placing rack 4, and a pressing plate 1101 is fixedly installed at the end of the electric telescopic rod 11. The pressing plate 1101 is used to press the paper 13 to be input. The storage control module 3 is based on an existing PLC control module and is used to implement control and storage operations. When performing input operations, first place the stacked paper 13 to be input into the placing rack 4. During the placing process, make the bottom of the stacked paper 13 to be input fit with the inner bottom of the placing rack 4, and the side of the paper 13 to be input fit with one side of the inner wall of the placing rack 4. Refer to Figure 5 , after placing, the electric telescopic rod 11 operates to press the paper 13 to be input through the pressing plate 1101;

[0032] Further, refer to Figure 5 , Figure 6 , Figure 8 , Figure 9, a paper outlet slot 401 is provided inside the placement rack 4. A limiting rod 17 is rotatably installed inside the paper outlet slot 401. An outer sleeve 18 is fixedly sleeved on the outer side of the limiting rod 17. A plurality of feeding plates 1801 are fixed on the outer side of the outer sleeve 18. The feeding plates 1801 are used to rotate with the outer sleeve 18 to pull out the papers 13 to be entered. The placement rack 4 is installed obliquely and the included angle between the inner side of the bottom of the placement rack 4 is less than 90°. As the papers 13 to be entered are pressed tightly, by driving the outer sleeve 18 through the rotation of the limiting rod 17, the feeding plates 1801 can rotate to pull out the bottommost stacked papers 13 to be entered, and then pull them out through the paper outlet slot 401. The limiting rod 17 is driven by a separate motor for operation;

[0033] Specifically, since the included angle between the inner side of the bottom of the placement rack 4 is less than 90°, when placing the papers 13 to be entered, the papers 13 to be entered can be stacked obliquely upward, so that the ends of the papers 13 to be entered are staggered, which is convenient for feeding operation and can avoid jamming during the feeding process or the phenomenon of multiple papers being pulled out at the same time;

[0034] Further, refer to Figure 7 , an upper clamping plate 6 and a lower clamping plate 7 are respectively fixedly installed inside the machine body 1. Scanning modules 8 are fixedly installed on the inner sides of the upper clamping plate 6 and the lower clamping plate 7, which are used to scan the papers 13 to be entered. Input belts 9 and output belts 10 are rotatably connected to both ends of the inner sides of the upper clamping plate 6 and the lower clamping plate 7, which are used to input and output the papers 13 to be entered. As the pulled-out papers contact the running input belt 9, the papers 13 to be entered can enter between the upper clamping plate 6 and the lower clamping plate 7, and after being scanned on both sides by the scanning module 8, they are output by the running output belt 10. The input belt 9 and the output belt 10 are both driven by separate motors, which will not be elaborated here;

[0035] Further, refer to Figures 1-9 , anti-slip pads 1802 are fixedly installed at the ends of the plurality of feeding plates 1801. An outer limiting ring 19 is fixedly installed inside the paper outlet slot 401. The outer limiting ring 19 is coaxial with the limiting rod 17, and a sponge cushion plate 20 is fixedly installed inside the outer limiting ring 19. A storage cylinder 14 is fixedly installed on the outer side of the placement rack 4. A liquid infusion tube 1401 is connected between the storage cylinder 14 and the sponge cushion plate 20. A solenoid valve is installed inside the liquid infusion tube 1401. Through the cooperation of the anti-slip pad 1802 and the sponge cushion plate 20, when the device is running, the solenoid valve is opened, and the liquid inside the storage cylinder 14 can enter the sponge cushion plate 20 through the liquid infusion tube 1401. As the running anti-slip pad 1802 contacts the sponge cushion plate 20, the anti-slip pad 1802 can always be kept moist, increasing the friction between the anti-slip pad 1802 and the papers 13 to be entered, ensuring the pulling-out effect of the papers 13 to be entered. The solenoid valve is an existing device and is controlled based on the storage control module 3;

[0036] Furthermore, referring to Figure 8 and Figure 9 , a scraping end 1901 is fixedly installed at the end of the outer limiting ring 19.

When the anti-slip gasket 1802 operates to pick out the paper to be input 13, as the anti-slip gasket 1802 rotates to the scraping end 1901, the scraping end 1901 can separate the anti-slip gasket 1802 from the paper to be input 13, avoiding the adhesion of the paper to be input 13 to the anti-slip gasket 1802 when the paper to be input 13 is picked out, which may cause curling and wrinkling at the end of the paper to be input 13;

[0037] Furthermore, a vibration motor 12 is fixedly installed at the bottom of the placement rack 4. Through the setting of the vibration motor 12, after the stacked papers to be input 13 are placed inside the placement rack 4, as the vibration motor 12 operates, the ends of the papers to be input 13 can better fit the inner wall of one side of the placement rack 4, and then the pressing operation is performed by the pressing plate 1101 to further ensure the subsequent feeding effect;

As the papers 13 to be input are pressed, the limiting rod 17 rotates to drive the outer sleeve 18 to operate, and the feeding plates 1801 can rotate to pull out the bottommost stacked papers 13 to be input, and then pull them out through the paper outlet slot 401. The limiting rod 17 is driven by a separate motor for operation;

[0044] Specifically, by making the included angle between the inner bottom of the bottom of the placement rack 4 less than 90°, when placing the papers 13 to be input, the papers 13 to be input can be stacked obliquely upward, so that the ends of the papers 13 to be input are staggered, which is convenient for feeding operations and can avoid jamming or multiple papers being pulled out simultaneously during the feeding process;
