[0027] Working process

[0028] When in use, the material first enters the input section 201 of the device. Before the material is cut, the pressure bar assembly 6 located at the front side of the input section 201 moves the pressure bar 601 downward and contacts the conveying surface 2 through the telescopic action of the cylinder 27, and the material is initially pressed down and fixed to ensure the stability and accuracy of the material during cutting. At the rear side of the input section 201, the first pressure roller 11 and the second pressure roller 12 apply appropriate pressure to the material through the adjustment of the first chute 9 and the second chute 10 to avoid the problem of warping or unevenness of the material in the rejection section 203. In the rejection section 203 between the input section 201 and the output section 202, the device can identify and reject non-conforming products to improve production efficiency and product quality. On the slide rail fixing plate 19 at the rear end of the output section 202, the third pressure roller 22 and the fourth pressure roller 23 are set at different heights through the fourth chute 20 and the fifth chute 21, which helps the smooth transition of the material. The stacking baffle 26 can be adjusted in position through the slide rail 25 and the slide block 5 to guide the materials to be neatly stacked, which is convenient for subsequent collection and packaging.

[0029] In summary, the utility model can level the material during the transmission and guiding process, and has the advantages of good leveling effect and strong practicality.
