The face paper g having a large longitudinal dimension is subjected to side positioning using the second side pull gage positioning mechanism 5 (see fig. 11), and the face paper g having a small longitudinal dimension is subjected to side positioning using the first side pull gage positioning mechanism 4 (see fig. 10). According to the facial tissues g with different sizes, the side pull gauge positioning mechanisms arranged at different positions are selected to perform effective side positioning, so that the phenomenon that the facial tissues g are pulled obliquely can be effectively avoided; the paper pasting machine can ensure the neatness of the pasting of the surface paper g and the bottom paper after the glue is applied, improve the product yield, and reduce the paper waste and the production cost. Three or more side pull gauge positioning mechanisms are also suitable, and are not described herein.

The first side lay positioning mechanism 4 will be described in detail below. In this embodiment, the first side pull gauge positioning mechanism 4 includes a side pull gauge 41, a side pull gauge adjusting structure 42 and a telescopic gap bridge 43, wherein the side pull gauge 41 is slidably mounted on the upstream paper conveying table 11 along a direction (transverse direction) perpendicular to the facial paper conveying direction by means of a slide rail and slider structure, and the side pull gauge adjusting structure 42 is used for driving the side pull gauge 41 to slide for position adjustment so as to adapt to facial paper g with different transverse dimensions; one end of the telescopic gap bridge 43 is connected with the side pull gauge 41, the other end of the telescopic gap bridge is connected with the upstream paper conveying table 11, and when the side pull gauge 41 slides transversely, the telescopic gap bridge 43 can stretch and retract adaptively.

The end face cam structure 416 comprises a cam lobe portion arranged on the end face of the shaft sleeve in a shaft sleeve mode, the shaft sleeve and the power transmission shaft 44 are connected through a key, relative axial movement can be achieved, synchronous rotation can be achieved, and transverse adjustment and power transmission are achieved without interference.

In practical operation, the second swing arm 414 swings periodically around the hinge ear 4111 along with the rotation of the end cam structure 416 (driven by the power transmission shaft 44), and at the same time, the first swing arm 412 also swings periodically and steadily under the action of the first elastic member 4151, the paper pressing plate 419 and the paper pressing roller 413 on the first swing arm 412 reciprocate up and down along with the swing of the first swing arm 412, i.e., periodically approach and depart from the paper supporting roller 417, the driving structure drives the paper supporting roller 417 to rotate, and the rotating paper supporting roller 417 and the paper pressing roller 413 cooperate to pull the facial tissues g between the paper pressing plate 419 and the paper supporting plate 418 to achieve side positioning.

In addition to the roller-type side pull gauges disclosed above, magnetic strip-type side pull gauges or pneumatic side pull gauges may also be used in the present embodiment; any side pull gauge 41 that can achieve the positioning of the tissue side is suitable for this embodiment; and will not be described in detail herein.

In this embodiment, the side pull gauge adjusting structure 42 includes a rotary driving member, a lead screw connected to the rotary driving member, and a nut threadedly connected to the lead screw; the side pull gauge 41 is fixedly connected with the nut.

Considering that when the side-pulling positioning mechanism pulls the facial tissue g, the adsorption positioning of the facial tissue g on the upstream facial tissue conveying mechanism 21 needs to be released, therefore, a plurality of vacuum air suction structures 214 which work independently and are closed without interference are arranged at intervals along the facial tissue conveying direction, and each vacuum air suction structure 214 comprises an air suction box and an air suction motor which is arranged in the air suction box and works independently. The vacuum air suction structure 214 is matched with the vacuum suction hole 213 and is used for adsorbing and positioning the facial tissue g on the first conveying belt 212; when the side pull positioning mechanism performs side positioning on the facial tissue g, the vacuum air suction structure 214 for performing adsorption positioning on the facial tissue g stops working, namely the vacuum air suction structure 214 close to the currently used side pull positioning mechanism stops working. The downstream tissue transport mechanism 22 may preferably be an existing mechanism and will not be described in detail herein.

According to the longitudinal size of the facial tissues g, one side pull gauge positioning mechanism is selected to be used (the other side pull gauge positioning mechanism adjusts the transverse position of the other side pull gauge positioning mechanism to be away from the facial tissues g, the facial tissues g cannot be pulled and is not used by default, or the other side pull gauge positioning mechanism is not used directly), the conveying speed of the upstream facial tissue conveying mechanism 21 is adjusted, and the problem that two adjacent facial tissues g are overlapped too much and pulled at the same time is solved; the facial tissue feeding device a transfers the facial tissues g to an upstream facial tissue conveying mechanism 21 in a facial tissue conveying device b of the high-speed laminating machine one by one, the upstream facial tissue conveying mechanism 21 carries out fish-scale paper feeding, when the frontmost facial tissues g are conveyed to a facial tissue front stop gauge 3, the facial tissue front stop gauge 3 acts (the roller type conveying mechanism 24 stops conveying), the forward movement of the facial tissues g is blocked to carry out front positioning on the facial tissues g, after the front positioning, the side selected for use pulls a regular positioning mechanism to act, and the facial tissues g are pulled to carry out effective side positioning on the facial tissues g; after the positioning is completed, the paper enters the downstream tissue conveying mechanism 22 under the transitional conveying of the roller type conveying mechanism 24.

Subsequently, the face paper g and the gummed base paper simultaneously enter the facing mounting device f, and the facing mounting device f mounts the face paper g and the base paper.

Because the selected side pull gauge positioning mechanism is matched with the facial tissue g under the current size, the phenomenon that the facial tissue g is pulled obliquely can be effectively avoided, the neat type of lamination mounting can be guaranteed, the yield of the mounted product is improved, and the paper waste and the production cost are reduced.
