[0038] like Figure 4As shown, the cardboard E moves from right to left. Depending on the size of the cardboard E, the left push claw assembly A can be set to move left or right, or the right push claw assembly B can be set to move left or right. It is also possible to set both the left push claw assembly A and the right push claw assembly B to move left or right. Both the left push claw assembly A and the right push claw assembly B move left and right in a direction parallel to the push conveyor belt C of the alignment section.
[0039] The left push claw assembly A includes a driving gear, a driven gear, a transmission belt (or a transmission chain) and N left push claws A1, where N ≥ 2, and the N left push claws A1 are evenly distributed and installed on the transmission belt (or transmission chain).
[0040] The driving gear and the driven gear are respectively engaged with the two ends of the transmission belt, and 2 or 4 left push claws A1 are evenly distributed and installed on each transmission belt. Figure 3-7 As shown, the left push claw assembly A has two transmission belts, two driving gears and two driven gears, thus forming a symmetrical structure; two left push claws A1 are evenly distributed and installed on each transmission belt. The left push claw A1 is set to be L-shaped, and the specific length of the left push claw A1 can be specifically designed according to the machine size.
[0041] The driving gear is fixedly mounted on a rotating shaft, which is rotatably mounted on the left mounting plate A2 via a bearing. The rotating shaft is rotatably connected to the output shaft of the first servo motor. The driven gear is rotatably mounted on a fixed shaft via a bearing, which is also fixed to the left mounting plate A2. Therefore, when the first servo motor is operating, it rotates the rotating shaft, which in turn drives the driving gear, which in turn drives the drive belt, causing the left push pawl A1 on the drive belt to circulate.
[0042] The left mounting plate A2 is slidably mounted on a frame (not shown), enabling left and right movement of the left push claw assembly A. The left push claw assembly A is positioned below or above the cardboard E, so the left push claw A1 can be positioned above or below the cardboard E.
[0043] The right push claw assembly B includes a driving gear, a driven gear, a transmission belt (or a transmission chain) and M right push claws B1, where M ≥ 2, and the M right push claws B1 are evenly distributed and installed on the transmission belt (or transmission chain).
[0044] The driving gear and the driven gear are respectively engaged with the two ends of the transmission belt, and 2 or 4 right push claws B1 are evenly distributed and installed on each transmission belt. Figure 3-7 As shown, the right push claw assembly B has two transmission belts, two driving gears and two driven gears, thus forming a symmetrical structure; two right push claws B1 are evenly distributed and installed on each transmission belt. The right push claw B1 is set to be L-shaped, and the specific length of the right push claw B1 can be specifically designed according to the machine size.
[0045] The driving gear is fixedly mounted on a rotating shaft, which is rotatably mounted on the right mounting plate B2 via a bearing. The rotating shaft is connected to the output shaft of the second servo motor. The driven gear is rotatably mounted on a fixed shaft via a bearing, which is also fixed to the right mounting plate B2. Therefore, when the second servo motor is in operation, it rotates the rotating shaft, which in turn drives the driving gear, which in turn drives the transmission belt, causing the right push pawl B1 on the transmission belt to circulate.
[0046] The right mounting plate B2 is slidably mounted on a frame (not shown), enabling left and right movement of the right push claw assembly B. The right push claw assembly B is positioned below or above the cardboard E, so the right push claw B1 can be positioned above or below the cardboard E.
[0047] The paper feed conveyor belt conveys two sheets of cardboard E onto the alignment conveyor belt C. A left push claw A1 abuts the rear end of one sheet of cardboard E, while a right push claw B1 abuts the rear end of the other sheet of cardboard E. The side push plates of a side push plate assembly D (not shown) push and join the two sheets of cardboard E. It should be noted that the side push plate assembly D can be implemented using a linear slide, the slider of which is fixedly connected to the side push plate, thereby pushing the sheets of cardboard E inward.
[0048] The push-pull conveyor belt C includes a push-pull down belt C1 and a push-pull support belt C2. The distance between the push-pull down belt C1 and the push-pull support belt C2 is adapted to the thickness of the paperboard E. The support surface of the push-pull support belt C2 is flush with the support surface of the paper feed conveyor belt. The push-pull down belt C1 is shorter than the push-pull support belt C2, and the end of the push-pull support belt C2 is aligned with the end of the push-pull down belt C1.
[0049] It should be noted that the conveyor belt involved in this embodiment is a simplified design, but it can be designed in a more complicated way according to actual applications, such as Figure 8 shown.

[0055] The electric eye monitors the position of the cardboard E in real time, such as Figure 5 As shown, when the rear ends of the two sheets of cardboard E separate from the starting end of the push-to-align conveyor belt C, the left push claw A1 of the left push claw assembly A and the right push claw B1 of the right push claw assembly B simultaneously activate and quickly push the sheets E to the rear ends. While the left and right push claws A1 and B1 are simultaneously pushing the sheets E, the paper feed conveyor belt continues to operate, thereby continuously conveying the two sheets of cardboard E from different groups.
[0056] like Figure 6 As shown, before the front end of any one of the two cardboards E enters the downward pressure belt of the push conveyor belt C, the moving speed of the left push claw A1 is set to , the moving speed of the right push claw B1 And the moving speed of the support belt of the push conveyor belt C ,in, = > The left push claw A1 and the right push claw B1 push the two pieces of cardboard E to align, by adjusting the speed of the push claw and the speed difference of the push conveyor belt C (specifically, the push support belt C2), so as to achieve the two pieces of cardboard E from Figures 1 to 2 Alignment changes.
[0057] At the same time, the side push plates on the left and right sides push the two pieces of cardboard E inward to splice them together.
[0058] Complete the alignment and splicing of the two pieces of cardboard E, as shown in the following example: Figure 6 As shown, the front ends of the two cardboards E enter the downward pressure belt of the push conveyor belt C at the same time, and the moving speed of the left push claw A1 is set. , the moving speed of the right push claw B1 And the moving speed of the support belt of the push conveyor belt C ,in, = = .
[0059] like Figure 7As shown, when the left pushing claw A1 is separated from the cardboard E it abuts against or when the right pushing claw B1 is separated from the cardboard E it abuts against, another left pushing claw A1 among the N left pushing claws A1 of the left pushing claw assembly A enters the standby position, and at the same time, another right pushing claw B1 among the M right pushing claws B1 of the right pushing claw assembly B enters the standby position;
[0060] Wait for the next set of two cardboards E and repeat steps S2-S6.
[0061] During the entire working process, the left push claw A1 and the right push claw B1 always maintain consistent working operation.
[0062] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the methods and technical content disclosed above to make many possible variations and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations.
