For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0022] like Figure 3-8 As shown, a traveling double-piece cardboard pushing and aligning device is provided, which is mainly composed of a left push claw assembly A, a right push claw assembly B, a pushing and aligning portion conveying belt C and a side push plate assembly D, etc., thereby realizing a traveling and aligning method for double-piece cardboards.

[0023] like Figure 4 As shown, the cardboard E moves from right to left. According to the size of the cardboard E, the left push claw assembly A can move left and right or the right push claw assembly B can move left and right. It can also be set that both the left push claw assembly A and the right push claw assembly B can move left and right.

[0024] 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, wherein N ≥ 2, and the N left push claws A1 are evenly distributed and installed on the transmission belt (or transmission chain).

[0025] The driving gear and the driven gear are respectively meshed 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 2 transmission belts, 2 driving gears and 2 driven gears, thereby forming a symmetrical structure; 2 left push claws A1 are evenly distributed and installed on each transmission belt, and the left push claw A1 is set to be L-shaped. The specific length of the left push claw A1 can be specifically designed according to the machine size.

[0026] The driving gear is fixedly mounted on the rotating shaft, which is rotatably mounted on the left mounting plate A2 through a bearing, and the rotating shaft is connected to the output shaft of the first servo motor. The driven gear is rotatably mounted on the fixed shaft through a bearing, and the fixed shaft is fixedly mounted on the left mounting plate A2. Therefore, when the first servo motor is running, it drives the rotating shaft to rotate, thereby driving the driving gear to rotate, and then drives the transmission belt to move, so that the left push claw A1 on the transmission belt can move cyclically.

[0027] The left mounting plate A2 is slidably mounted on the frame (not shown in the figure) to realize the left and right movement of the left push claw assembly A. The left push claw assembly A is located below or above the cardboard E, so the left push claw A1 can be located above the cardboard E or below the cardboard E.

The specific length of the right push claw B1 can be specifically designed according to the machine size.

[0030] The driving gear is fixedly mounted on the rotating shaft, which is rotatably mounted on the right mounting plate B2 through a bearing, and the output shaft of the second servo motor is connected to the rotating shaft. The driven gear is rotatably mounted on the fixed shaft through a bearing, and the fixed shaft is fixedly mounted on the right mounting plate B2. Therefore, when the second servo motor is running, it drives the rotating shaft to rotate, thereby driving the driving gear to rotate, and then drives the transmission belt to move, so that the right push claw B1 on the transmission belt can move cyclically.

[0031] The right mounting plate B2 is slidably mounted on the frame (not shown in the figure) to realize the left and right movement of the right push claw assembly B. The right push claw assembly B is located below or above the cardboard E, so the right push claw B1 can be located above the cardboard E or below the cardboard E.

[0032] The conveyor belt of the paper feeding unit conveys two pieces of cardboard E to the conveyor belt C of the pushing unit, a left push claw A1 abuts against the rear end of one piece of cardboard E, and a right push claw B1 abuts against the rear end of another piece of cardboard E. The side push plate of the side push plate assembly D (not shown in the drawings) pushes and splices the two pieces of cardboard E. It should be noted that the side push plate assembly D can be implemented by a linear slide, and the slider of the linear slide is fixedly connected to the side push plate, so as to push the cardboard E inward.

[0033] The conveying belt C of the pushing part includes a pressing belt C1 of the pushing part and a supporting belt C2 of the pushing part. The distance between the pressing belt C1 of the pushing part and the supporting belt C2 of the pushing part is adapted to the thickness of the paperboard E.

[0038] Step S4: Figure 6 As shown, before the front end of any one of the two paperboards E enters the downward pressing belt of the pushing conveyor belt C, 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 supporting 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, and the speed difference between the push claw speed and the push conveyor belt C (specifically, the push support belt C2) is adjusted to achieve the two pieces of cardboard E from Figure 1 to Figure 2 Alignment changes.

[0039] 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.

[0040] Step S5: Complete the alignment and splicing of the two pieces of cardboard E, such as Figure 6 As shown, the front ends of the two pieces of cardboard E simultaneously enter the downward pressing belt of the pushing conveyor belt C, 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 supporting belt of the push conveyor belt C ,in, = = .
