In this embodiment, as shown in Figure 3 and 5 shown, there are 2 transmission chains, 2 driving gears and 2 driven gears, forming a symmetrical structure; 2 front pushing claws B1 are evenly distributed and installed on each transmission chain, and the front pushing claw B1 is set to L-shaped, and the specific length of the front pushing claw B1 can be designed according to the size of the machine.

[0041] The driving gear is fixedly installed on the rotating shaft, the rotating shaft is rotatably installed on the front mounting plate B2 through the bearing, and the rotating shaft is in transmission connection with the output shaft of the first servo motor. The driven gear is rotatably installed on the fixed shaft through the bearing, and the fixed shaft is fixedly installed on the front mounting plate B2. Therefore, the first servo motor operates to drive the rotating shaft to rotate, thereby driving the driving gear to rotate, and then driving the transmission chain to move, so that the front pushing claw B1 on the transmission chain can move circularly.

[0042] The front mounting plate B2 is slidably installed on the rack (not shown in the figure), so that the front and rear movement of the front pushing claw assembly B can be realized. The front pushing claw assembly B is above or below the paperboard E, so that the front pushing claw B1 can be above or below the paperboard E.

[0043] The rear pushing claw assembly C includes a driving gear, a driven gear, a transmission chain (or a transmission belt), and M rear pushing claws C1, where M≥2, and the M rear pushing claws C1 are evenly distributed and installed on the transmission chain (or the transmission belt).

[0044] The driving gear and the driven gear are respectively engaged with both ends of the transmission chain, and 2 or 4 rear pushing claws C1 are evenly distributed and installed on each transmission chain. In this embodiment, as shown in Figure 3 and 4As shown, there are 2 transmission chains, 2 driving gears and 2 driven gears, forming a symmetrical structure; 2 rear push claws C1 are evenly distributed and installed on each transmission chain, the rear push claw C1 is set to L type, and the specific length of the rear push claw C1 can be designed according to the size of the machine.

[0045] The driving gear is fixedly installed on the rotating shaft, the rotating shaft is rotatably installed on the rear mounting plate C2 through the bearing, and the output shaft of the second servo motor is drivingly connected with the rotating shaft. The driven gear is rotatably installed on the fixed shaft through the bearing, and the fixed shaft is fixedly installed on the rear mounting plate C2. Therefore, the second servo motor operates to drive the rotating shaft to rotate, thereby driving the driving gear to rotate, and then driving the transmission chain to move, so that the rear push claw C1 on the transmission chain can move circularly.

[0046] The rear mounting plate C2 is slidingly installed on the rack (not shown in the figure), so that the front and rear movement of the rear push claw assembly C can be realized. The rear push claw assembly C is above or below the paperboard E, so that the rear push claw C1 can be above or below the paperboard E.

[0047] The folding part output belt A includes a folding part pressing belt A1 and a folding part supporting belt A2, and the interval between the folding part pressing belt A1 and the folding part supporting belt A2 is matched with the thickness of the folded paperboard E.

[0049] The supporting surface of the folding part supporting belt A2 is flush with the supporting surface of the nail box part supporting belt D2.

[0050] The working process of the embodiment will be further described below:

[0051] The front push claw assembly B and the rear push claw assembly C are in standby state, as shown in Figure 4 ;

[0052] At this time, one of the N front push claws B1 of the front push claw assembly B is in standby position: the front push claw B1 is vertically arranged at the end of the folding part output belt A, where N≥2;

[0053] One of the M rear push claws C1 of the rear push claw assembly C is in standby position: the rear push claw C1 is parallel to the folding part output belt A, where M≥2.

[0054] After the paperboard E is folded by the folding part, the folded paperboard E is conveyed forward by the folding part output belt A.

[0055] The electric eye monitors the position of the paperboard E in real time. When the front end of the paperboard E contacts the front pushing claw B1, the front pushing claw B1 in standby position is started, and at the same time, the rear pushing claw C1 in standby position is started quickly to push the rear end of the paperboard E. At this time, the rear pushing claw C1 is perpendicular to the folding part output belt A. Figure 5

[0056] The front pushing claw B1 and the rear pushing claw C1 start to convey the paperboard E at the same time. The folding part output belt A continues to work to convey the folded paperboard E.

[0057] As shown in the figure, before the front end of the paperboard E enters the box nailing part input belt D and the rear end of the paperboard E leaves the folding part output belt A, the moving speed of the front pushing claw B1 and the moving speed of the rear pushing claw C1 are set, wherein the two pushing claws press and align the paperboard E. The pressing degree of the two pushing claws to the paperboard E is realized by adjusting the speed difference between the moving speed of the front pushing claw B1 and the moving speed of the rear pushing claw C1, so that the paperboard E changes from Figure 6 Figures 1 to 2

[0058] After the paperboard E enters the box nailing part input belt D, the alignment of the paperboard E is completed, and the moving speed of the front pushing claw B1, the moving speed of the rear pushing claw C1 and the conveying speed of the box nailing part input belt D are set, wherein

[0059] As shown in the figure, when the rear pushing claw C1 is separated from the rear end of the paperboard E, another rear pushing claw C1 in the M rear pushing claws C1 of the rear pushing claw assembly C enters the standby position. Figure 7

[0060] When the rear end of the paperboard E is separated from the end of the folding part output belt A, another front pushing claw B1 in the N front pushing claws B1 of the front pushing claw assembly B enters the standby position.

[0061] The next folded paperboard E is waited. The continuous production is realized by the cycle.

[0062] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Any person skilled in the art can make many possible changes and modifications to the technical scheme of the present application, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical scheme of the present application, by using the disclosed methods and technical contents.
