[0024] The bottom paper conveying device of the paper pasting machine with double positioning according to any one of claims 1 or 2, characterized in that at least two second driving rollers 103 are rotatably provided at the lower end of the frame plate 1. The end faces of the second driving rollers 103 are provided with transmission parts 1031 in an array. The diameter of the transmission parts 1031 is larger than that of the second transmission rollers. The transmission parts 1031 protrude from the notches 102. A second belt pulley 104 is coaxially provided at the end of the second driving roller 103.

[0025] Further, a connecting frame 601 is provided between the pressing wheel 6 and the second driving shaft 4. The pressing wheel 6 is rotatably arranged at the front part of the connecting frame 601.

[0026] During operation, the first driving roller 2 at the lower rear end of the rack board 1 rotates. The upper part of the first driving roller 2 protrudes from the end face of the rack board 1. The driving method here is driven by a driving motor outside the device or the driving part in the device through a transmission belt to drive the first pulley 201 on the side. A first eccentric wheel 2011 is coaxially rotated at the side end of the first pulley 201. A first driving shaft 3 is rotatably provided at the lower end of the rack board 1. The rotational connection mode of the first driving shaft 3 is realized through a bearing seat. A first lever 301 is coaxially rotated at the end of the driving shaft. The end of the air cylinder is located above the first eccentric wheel 2011. And a bearing is rotatably provided at the inner end of the first lever 301. A limiting hook 5 is arranged in a row on the first driving shaft 3. The rear end of the limiting hook 5 is fixedly connected by driving. The fixing method is preferably the fixing method of a bolt fixing seat. The front part of the limiting hook 5 bends upward. And the front part of the limiting hook 5 protrudes from the perforation 101 arranged in a row on the rack board 1 in an active manner. The protruding part is used to block the rear base paper. In order to facilitate the lowering and protruding of the limiting hook 5, the perforation 101 has a certain length. When the first driving roller 2 rotates, the first eccentric wheel 2011 rotates simultaneously. The highest point of the protruding part of the first eccentric wheel 2011 will lift the first lever 301. While lifting the first lever 301, the first driving shaft 3 that rotates coaxially rotates. The limiting hook 5 simultaneously makes a circular motion following the first driving shaft 3. At this time, the front end of the limiting hook 5 descends below the rack board 1. When the lowest end of the first eccentric wheel 2011 contacts the bearing, the first lever 301 descends. At the same time, the limiting hook 5 rises. The rising principle is that the limiting hook 5 rotates and rises through the weight of the first lever 301 descending. This action can realize that when the first driving roller 2 conveys the base paper, the protrusion of the front end of the limiting hook 5 on the rack board 1 descends. To realize the distance limitation between the rear base paper and the front base paper. At least two second driving rollers 103 are rotatably provided at the lower end of the rack board 1. To assist in the transmission of the base paper. And facilitate the transmission of the base paper. A transmission part 1031 is arranged in a row on the second driving roller 103. The diameter of the transmission part 1031 is larger than the diameter of the second driving roller 103. And the transmission part 1031 protrudes through the notch 102 at the end of the rack board 1. A second driving shaft 4 is rotatably provided at the upper end of the rack board 1. A second lever 401 is coaxially rotated at the end of the second driving shaft 4. A bearing is rotatably provided at the inner side end of the second lever 401. A second eccentric wheel 202 is coaxially rotated at the end of the first driving roller 2. The end of the second lever 401 is located above the second eccentric wheel 202. A pressing wheel 6 is arranged in a row on the second driving shaft 4. A connecting frame 601 is provided between the pressing wheel 6 and the second driving shaft 4. The connecting frame 601 is fixed by a bolt or the fixing method of a fixing seat. The pressing wheel 6 is rotatably arranged at the front end of the connecting frame 601. And the position of the pressing wheel 6 corresponds to the position of the front second driving roller 103. When the second eccentric wheel 202 rotates following the first driving roller 2, the highest end of the second eccentric wheel 202 will lift the second lever 401. At this time, the pressing wheel 6 rises. When the second eccentric wheel 202 rotates to the lowest end, the pressing wheel 6 falls due to the weight.And a second belt pulley 104 is provided on the side of the second driving roller 103 and is chain-driven by the same driving source as the first driving roller 2. An included angle is provided between the first eccentric wheel 2011 and the second eccentric wheel 202, which can realize the linkage of pressing and rolling between the base papers and the linkage of blocking and limiting, can realize the positioning of the pressing wheel 6 and the double positioning of the limiting hook 5, and ensure that a certain distance can be opened between the rear base paper and the front base paper during the conveying process.
