Compared with the roll bottom paper, the single bottom paper 13 can be stopped and replaced at any time, thereby avoiding the increase of production cost due to excessive waste of bottom paper; the gluing module 10 is used to glue the surface of the single bottom paper 13 output by the bottom paper feeding module, so as to make the single bottom paper 13 and the single face paper 12 fit together, and the bottom paper conveying module 9 is used to convey the glued single bottom paper 13 to the double-layer face paper conveying module Two output ends are used to laminate the single bottom paper 13 and the single face paper 12 of the upper layer, or to laminate the single bottom paper 13 and the single face paper 12 of the middle layer according to the actual order requirements. The laminating and conveying module is arranged near the output end of the double-layer paper conveying module, and the laminating and conveying module is used to press and merge the single face paper 12 and the single bottom paper 13 after gluing to form a mounting paper, so as to realize the laminating of the single face paper 12 and the single bottom paper 13, and the laminating and conveying module can convey the mounting paper to finally form the finished mounting paper and export it.

[0025] Specifically, the double-layer paper conveying module includes an upper layer paper conveying unit 5 and a middle layer paper conveying unit 6 which are arranged in sequence from top to bottom. Through the double-layer design of the upper layer paper conveying unit 5 and the middle layer paper conveying unit 6, the single sheet of paper 12 on the upper layer and the single sheet of paper 12 on the middle layer can be used interchangeably, which greatly improves the order changing efficiency and avoids affecting the overall production efficiency due to the long order changing time.

The upper flyer 1 is connected to the input end of the upper tissue paper conveying unit 5, and the middle flyer 2 is connected to the input end of the middle tissue paper conveying unit 6, so as to realize the separate supply and output of the upper single tissue paper 12 and the middle single tissue paper 12.

[0027] An upper-layer bridge conveying component 3 is installed on the upper-layer paper conveying unit 5. The upper-layer bridge conveying component 3 is used to stack and convey the single-sheet paper 12 of the upper layer and correct the side gauge during the conveying process to ensure the accurate position of the single-sheet paper 12 of the upper layer. A middle-layer bridge conveying component 4 is installed on the middle-layer paper conveying unit 6. The middle-layer bridge conveying component 4 is used to stack and convey the single-sheet paper 12 of the middle layer and correct the side gauge during the conveying process to ensure the accurate position of the single-sheet paper 12 of the middle layer. Multiple single-sheet paper 12 on the same layer are arranged and stacked in a shingled manner, thereby ensuring the stable conveyance of the single-sheet paper 12.

[0028] In every two adjacent sheets of tissue paper 12, the first end of the sheet of tissue paper 12 at the rear is pressed against the second end of the sheet of tissue paper 12 at the front. This arrangement can prevent the sheets of tissue paper 12 from deviating or falling during transportation to a certain extent.

[0030] The upper layer laminating and conveying unit 7 and the middle layer laminating and conveying unit 8 are both provided with a laminating bellows 72, the air outlet of the laminating bellows 72 is toward the upper surface of the upper layer laminating and conveying unit 7 or the upper surface of the middle layer laminating and conveying unit 8, and the laminating bellows 72 is used to provide negative pressure suction for the upper layer laminating and conveying unit 7 or the middle layer laminating and conveying unit 8, thereby adsorbing the single sheet of face paper 12 and the single sheet of bottom paper 13 during the laminating process, avoiding large-scale displacement of the single sheet of face paper 12 and the single sheet of bottom paper 13, affecting the quality of the formed mounting paper, and even causing mounting failure.

[0031] A waste stripping unit 11 is provided between the upper layer laminating and conveying unit 7 and the middle layer laminating and conveying unit 8. A waste stripping bellows 111 is provided at the waste stripping unit 11. The wind outlet of the waste stripping bellows 111 faces the upper surface of the waste stripping unit 11. The waste stripping bellows 111 is used to provide negative pressure suction force at the waste stripping unit 11, thereby playing a role in assisting the conveyance of a single bottom paper 13. When the bottom paper conveying module 9 is replaced with a conveying roll bottom paper, the waste stripping unit 11 can suck the roll bottom paper of the previous order to the surface of the bottom paper conveying module 9 when switching orders and perform waste stripping, so that after the roll bottom paper is replaced, the face paper in the next order and the roll bottom paper in the next order can be laminated.

[0032] An upper inclined plane is provided at the front end of the upper layer paper conveying unit 5, and a middle inclined plane is provided at the front end of the middle layer paper conveying unit 6. A plurality of paper photoelectric sensors for detecting the position of a single sheet of paper 12 are provided on the upper inclined plane and the middle inclined plane. A plurality of bottom paper photoelectric sensors for detecting the position of a single sheet of bottom paper 13 are provided on the bottom paper conveying module 9. The paper photoelectric sensors and the bottom paper photoelectric sensors are both electrically connected to the controller, and the paper photoelectric sensors and the bottom paper photoelectric sensors can transmit the detected position signals to the controller, and the conveying speeds of the upper layer paper conveying unit 5, the middle layer paper conveying unit 6 and the bottom paper conveying module 9 are controlled respectively by the controller, so as to realize real-time detection of the position of the single sheet of paper 12 on the upper layer, the single sheet of paper 12 on the middle layer and the single sheet of bottom paper 13, and adjust the relative positions of the single sheet of paper 12 and the single sheet of bottom paper 13 according to the real-time position signals, so as to ensure that the single sheet of paper 12 and the single sheet of bottom paper 13 can be smoothly laminated when they are finally conveyed to the laminating conveying module. In actual application, by reasonably arranging the positions and numbers of the photoelectric sensors, it can be ensured that the single sheet of face paper 12 and the single sheet of bottom paper 13 entering the laminating part complete the laminating once. For example, taking the single sheet of facial paper 12 in the middle layer as an example, when the single sheet of facial paper 12 in the middle layer moves to the first facial paper photoelectric sensor, the first facial paper photoelectric sensor detects the single sheet of facial paper 12, and controls the bottom conveying module through the controller to start conveying the single sheet of bottom paper 13, and determines the speed ratio of the single sheet of facial paper 12 and the single sheet of bottom paper 13 according to the conveying speed of the single sheet of bottom paper 13. When the single sheet of bottom paper 13 reaches the position of the bottom paper photoelectric sensor after being coated with glue, the bottom paper photoelectric sensor detects the single sheet of bottom paper 13, and the single sheet of facial paper 12 reaches the second facial paper photoelectric sensor above the bottom paper photoelectric sensor. At this time, the relative positions of the single sheet of bottom paper 13 and the single sheet of facial paper 12 are determined according to the program calculation, and the single sheet of facial paper 12 is corrected by the front gauge correction element 61 of the middle layer of facial paper to ensure that the front gauge is aligned within ±0.5mm, and finally the single sheet of facial paper 12 and the single bottom paper 13 entering the laminating part are completed at the laminating conveying module.

[0033] A conveying bellows 91 is provided at the bottom paper conveying module 9, and the air outlet of the conveying bellows 91 is toward the upper surface of the bottom paper conveying module 9, and the conveying bellows 91 is used to provide negative pressure suction for the bottom paper conveying module 9, so as to facilitate the adsorption of the single bottom paper 13 being conveyed, thereby avoiding large-scale displacement of the single bottom paper 13 during the conveying process, which affects the alignment and bonding with the single surface paper 12.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
