[0063] The working principle of this utility model is as follows:

[0064] Pre-sale

[0065] In the initial state, the positioning table of the pre-folding mechanism 40 has the card paper 10 pre-folded in the previous cycle, the piston rods of the seventh driving member and the eighth driving member are retracted; the feeding station 81 of the four-station indexing disc 80 has no card paper 10 (at this time, the positioning jig located at the feeding station 81 is the positioning jig at the unloading station 84 after the card paper 10 on the positioning jig at the unloading station 84 is taken away by the second material moving mechanism 60, and the positioning jig at the unloading station 84 is rotated to the feeding station 81); the movable part of the first electric cylinder 32 of the first material moving mechanism 30 is located in the middle of its stroke, the first suction assembly A31 is located between the feeding conveying belt line 20 and the pre-folding mechanism 40, and the first suction assembly B33 is located between the pre-folding mechanism 40 and the four-station indexing disc 80.

[0066] In the direction of Figure 5 reference, the first electric cylinder 32 of the first material moving mechanism 30 drives the mounting plate 34 to move right, and then simultaneously drives the first suction assembly A31 and the first suction assembly B33 to move right. When the first suction assembly A31 moves to the position directly above the card paper 10 to be sucked on the feeding conveying belt line 20, and the first suction assembly B33 moves to the position directly above the card paper 10 pre-folded on the positioning table of the pre-folding mechanism 40, it stops. The piston rod of the first air cylinder 312 extends to drive the first suction disc A311 to move down, the first suction disc A311 sucks the card paper 10 to be sucked on the feeding conveying belt line 20, the piston rod of the second air cylinder 332 extends to drive the first suction disc B331 to move down, and the first suction disc B331 sucks the card paper 10 on the positioning table. Then the piston rod of the first air cylinder 312 retracts, the piston rod of the second air cylinder 332 retracts, the first electric cylinder 32 drives the mounting plate 34 to move left, and then simultaneously drives the first suction assembly A31 and the first suction assembly B33 to move left. When the first suction assembly A31 moves to the position directly above the positioning table, and the first suction assembly B33 moves to the position directly above the feeding station 81 of the four-station indexing disc 80, it stops. The piston rod of the first air cylinder 312 extends, the piston rod of the second air cylinder 332 extends, the first suction disc A311 places the sucked card paper 10 on the positioning table, and the first suction disc B331 places the sucked card paper 10 on the positioning jig of the feeding station 81 of the four-station indexing disc 80. Then the movable part of the first electric cylinder 32 of the first material moving mechanism 30 drives the mounting plate 34 to move left to the middle of its stroke. The card paper 10 placed on the positioning jig of the feeding station 81 is fixed and moved to the first edge folding station 82 through the rotation of the four-station indexing disc 80.

[0067] The piston rods of the seventh driving member and the eighth driving member extend to cooperate with the first positioning block 43 and the second positioning block 44 to position the card paper 10; the piston rod of the third air cylinder 42 extends to drive the pressing plate 510 to descend into the hole position, so that the first side wing 12 and the second side wing 13 change from a horizontal state to a state of being folded downward with the roots of the two as the base point, and the pre-folding of the first side wing 12 and the second side wing 13 is completed.

[0068] (2) On the four-station indexing plate 80, the feeding station 81 feeds the paper, the first folding mechanism 50 folds the right side of the horizontal part 11 of the cardboard 10, the second folding mechanism 90 folds the left side of the horizontal part 11 of the cardboard 10, and the unloading station 84 unloads the paper. The four stations on the four-station indexing plate 80 operate simultaneously. The working principle of each of the four stations is explained below:

[0069] Loading station 81

[0070] The first suction component B33 transfers the pre-folded cardboard 10 from the pre-folding mechanism 40 to the feeding station 81. The specific transfer process and the working principle of pre-folding have been described, and will not be repeated here.

[0071] The first folding mechanism 50 folds the right side of the horizontal portion 11 of the cardstock 10.

[0072] by Figure 4 The direction is taken as a reference, and the direction of the servo rotary motor 53 of the first folding mechanism 50 relative to the fixed plate 54 is defined as forward; in the initial state, the positions of the first folding plate 55, the second folding plate 56, and the pressure plate 510 are as follows: Figure 8 , Figure 9 As shown, the first folding plate 55 is entirely located in a vertical plane, the vertical plate 561 of the second folding plate 56 is located in a vertical plane, the pressure plate 510 is in a raised state, and the second folding plate 56 and the pressure plate 510 are located on both sides of the first folding plate 55 in a top-down view; the right side of the horizontal part 11 of the cardboard 10 is as shown... Figure 12 As shown;

[0073] The paper 10 at the loading station 81 is transferred to the first folding station 82 by the rotation of the four-station indexing plate 80. The third electric cylinder 52 drives the first folding module to move radially towards the four-station indexing plate 80, thereby driving the first folding plate 55 and the second folding plate 56 to insert forward towards the four-station indexing plate 80, so that the first folding plate 55 is directly above the right fourth quadrilateral plate 119 and the second folding plate 56 is directly below the right third quadrilateral plate 118. The second electric cylinder 51 drives the folding assembly to descend, so that the lower end face of the width of the first folding plate 55 presses against the right fourth quadrilateral plate 119 of the paper 10. The fifth cylinder 58 drives the fourth cylinder 57 to rise, and at the same time drives the second folding plate 56 to rise and pass through the notch 88 of the fixture plate 85, folding the right third quadrilateral plate 118 upward along the crease between the right third quadrilateral plate 118 and the right fourth quadrilateral plate 119, so that the right side of the horizontal part 11 of the paper 10 forms as shown in the figure.
