[0019] The paper-pushing mechanism 4 includes a rotating cylinder 401 fixed to the bottom of the adjusting seat 2, a first telescopic cylinder 402 is fixed to the bottom end of the output shaft of the rotating cylinder 401, an L-shaped insertion rod 403 is fixed to the bottom end of the output shaft of the first telescopic cylinder 402, and the two insertion rods 403 are symmetrically arranged. The rotating cylinder 401, the first telescopic cylinder 402 and the insertion rod 403 cooperate with each other. First, the output shaft of the first telescopic cylinder 402 drives the insertion rod 403 downward to be inserted between the marked page and the adjacent napkin paper, and then the output shaft of the rotating cylinder 401 drives the insertion rod 403 on the output shaft of the first telescopic cylinder 402 to rotate, so as to push a certain gap between the corresponding marked page and the adjacent napkin paper, such as Figure 3 As shown, the marked page of the stack of napkins is pushed in the direction of the arrow to separate it from the adjacent napkins behind, thereby effectively avoiding the problem of not being able to hook the paper.

[0020] Specifically, the mounting seat 1 is provided with two sets of height adjustment mechanisms 3 for lifting and lowering the adjustment seat 2. The height adjustment mechanism 3 includes two guide sleeves 301 embedded and fixed on the top of the mounting seat 1. The inner sliding sleeve of the guide sleeve 301 is provided with a guide rod 302 fixedly installed with the bottom of the adjustment seat 2. The bottoms of the two guide rods 302 on the same side are fixed with the same connecting cross plate 304. An adjusting screw 303 rotatably installed with the mounting seat 1 is provided between the two guide rods 302 on the same side.

After the insertion rod 403 pushes a certain gap between the marked page and the adjacent napkin, the output shaft of the second telescopic cylinder 505 drives the push rod 506 to insert into the gap pushed by the insertion rod 403, and then the output shaft of the flip cylinder 501 drives the flip shaft 502 to flip backward. The flip shaft 502 drives the push rod 506 on the output shaft of the second telescopic cylinder 505 and the napkin on the flip plate 503 to flip backward synchronously, so that the napkin between the rear side of the push rod 506 and the flip plate 503 is flipped onto the mounting seat 1.

Slide blocks 704 are fixed on both sides of the top of the pushing seat 702, and guide rails 705 fixedly installed on the bottom of the mounting seat 1 are slidably installed on the slider 704. The sliced ​​napkins on the mounting seat 1 are pushed onto the conveying mechanism by utilizing the cooperation of the transverse pushing cylinder 701, the pushing seat 702 and the pushing rod 703. In addition, the pushing seat 702 drives the slider 704 to slide on the guide rail 705, so that the pushing seat 702 can be pushed very smoothly at the bottom of the mounting seat 1.

This operation can effectively avoid the problem that the marked page cannot be hooked due to insufficient protrusion. At this time, the two transverse cylinders 601 and the two second telescopic cylinders 505 are started synchronously, and the output ends of the two transverse cylinders 601 respectively drive the corresponding paper stopper rods 602 to approach each other and insert them into the gap made by the insertion rod 403, so that the paper stopper rods 602 The un-stacked napkins at the rear side are blocked, and at the same time, the output shaft of the second telescopic cylinder 505 drives the push rod 506 to be inserted into the gap opened by the insertion rod 403, and then the output shaft of the flip cylinder 501 drives the flip shaft 502 to flip backward, and the flip shaft 502 drives the push rod 506 on the output shaft of the second telescopic cylinder 505 and the napkins on the flip plate 503 to flip backward synchronously, so that the napkins between the rear side of the push rod 506 and the flip plate 503 are flipped onto the mounting seat 1, and the output shaft of the horizontal push cylinder 701 drives the push seat 702 to move to the rear position, and the push seat 702 drives the slider 704 to slide on the guide rail 705, and the push seat 702 drives the push rod 703 to push out the sliced ​​napkins on the mounting seat 1. This design allows the push seat 702 to slide smoothly on the mounting seat 1 when the push cylinder 701 is working, so that the stack of napkins being pushed is more stable during the moving process.
