A hopper 2 and a conveying mechanism 3 are installed on the frame 1. The hopper 2 is located above the conveying mechanism 3, and a material dividing mechanism is provided between the two.

[0020] Reference Figure 2 、 Figure 3 The conveying mechanism 3 includes two sets of driven wheels 301 and driving wheels 302.

A lifting rod 701 is fixed on the horizontal side of the L-shaped bracket 7. A wheel shaft 304 is provided between the two driven wheels 301. A cam 305 is installed on the wheel shaft 304. A guide sleeve 9 is provided between the cam 305 and the L-shaped bracket 7. The upper end of the lifting rod 701 is fixedly connected to the L-shaped bracket 7, and the lower end passes through the annular surface of the guide sleeve 9 and the cam 305. To maintain contact, a ball bearing 702 is also provided at the lower end of the lifting rod 701 to reduce friction and wear; a spring 5 is arranged in the guide sleeve 9, and a positioning ring 703 is arranged on the lifting rod 701.

[0021] Reference Figure 4The material bin 2 comprises a limiting frame 201 fixedly arranged on the frame 1, the bottom side of the limiting frame 201 is provided with a material blocking plate 202, and the other side is slidably connected with the vertical side of the L-shaped bracket 7; in order to make the paperboard smoothly discharged from the lower end of the limiting frame 201, the top of the limiting frame 201 is provided with a pressing plate 203, one side of the top of the limiting frame 201 is hingedly connected with the pressing plate 203, and the other side is provided with a locking bolt 207, the locking bolt 207 is rotationally connected with the limiting frame 201, the pressing plate 203 is provided with a locking groove 208 matched with the locking bolt 207, and the locking bolt 207 is fixed to the top of the limiting frame 201 through the positioning groove 208; the pressing plate 203 is provided with a telescopic rod 204, the lower end of the telescopic rod 204 penetrates through the pressing plate 203 and is provided with a pressing foot 206 for contacting and pushing the paperboard, a pulling spring 205 is arranged on the section of the telescopic rod 204 above the pressing plate 203, the upper end of the pulling spring 205 is connected with the telescopic rod 204, and the lower end is abuttingly connected with the pressing plate 203, so that the paperboard in the material bin 2 is pushed downward to move downward to continuously feed.

[0022] In order to facilitate the understanding of the utility model, the following will be combined with Figure 1 - Figure 4 The working principle of the scheme will be described in detail:

[0023] With the rotation of the cam 305, the jacking rod 701 moves up and down. When the jacking rod 701 rises, it lifts the paperboard in the material bin 2, so that it is away from the conveying belt 303; when the jacking rod 701 descends, the paperboard at the lowermost part of the limiting frame 201 contacts the conveying belt 303 and is driven to slide out of the limiting frame 201; the paperboard above is kept in the limiting frame 201 under the blocking of the material blocking plate 202, so that the separation of the paperboard is realized; with the rotation of the cam 305, the conveying belt 303 carries out the paperboard in the limiting frame 201 one by one, realizes the automatic and continuous feeding of the paperboard, and effectively solves the problem that the paperboard is easily accumulated in the conveying process.
