Specifically, the correction mechanism 7 includes a cylinder and a shovel plate. The shovel plate has a stepped surface. The cylinder drives the shovel plate to move, and the stepped surface engages the side edge of the cardboard box, thereby correcting the orientation of the cardboard box.

[0061] The inner mold S flows between the mold placement station and the mold removal station, which is jointly achieved by the inner mold conveying mechanism 5 and the mold removal mechanism 6. Specifically, the inner mold conveying mechanism 5 continuously conveys the inner mold S. Specifically, the inner mold conveying mechanism 5 uses parallel double belts to convey the inner mold S, which makes the inner mold S more stable during the conveying process and prevents positional deviation. Specifically, the correction mechanism 7 is set on the inner mold conveying mechanism 5, and the correction mechanism 7 is used to correct the position of the inner mold S to be removed.

[0062] The mold-removing mechanism 6, corresponding to the mold-laying station and the mold-removing station, removes the inner mold S from the inner mold conveying mechanism 5 and places it into the cardboard box at the mold-laying station; it also removes the inner mold S from the cardboard box at the mold-removing station and moves it to the inner mold conveying mechanism 5. Specifically, as follows... Figure 7 As shown, combined with Figure 8 The mold-taking mechanism 6 includes a fifth linear module 62, a sixth linear module 63, a double-headed double-outlet cylinder 64, and two clamping plates 65. The fifth linear module 62 is connected to the frame 1 and the sixth linear module 63 respectively, and drives the sixth linear module 63 to move back and forth between the inner mold conveying mechanism 5 and the mold placement station or the mold-taking station. The sixth linear module 63 drives the double-headed double-outlet cylinder 64 to move up and down, and the double-headed double-outlet cylinder 64 drives the two clamping plates 65 to move relative to each other or away from each other. In this way, the fifth linear module 62 drives the sixth linear module 63 to move back and forth between the inner mold conveying mechanism 5 and the mold placement station or between the mold-taking station and the inner mold conveying mechanism 5. The sixth linear module 63 uses a double-stroke cylinder, first quickly driving the two clamping plates 65 to move above the cardboard box, and then slowly driving the two clamping plates 65 to extend into the cardboard box. Specifically, the inner mold S has two straight holes S1 on its surface, and a transverse hole S2 extends from the straight holes S1 toward the middle of the inner mold S. The bottom of the clamping plate 65 is provided with an "L"-shaped positioning pin 66, and the "L"-shaped positioning pins 66 of the two clamping plates 65 are arranged opposite each other. In this way, the "L"-shaped positioning pins 66 can quickly locate the straight holes S1 and improve the stability of clamping.

[0063] The defoaming mechanism 2 is located at the defoaming station and applies pressure to the cardboard box to remove bubbles. Specifically, as shown... Figure 9As shown, the bubble removing mechanism 2 comprises two first linear modules 21, two first pressing plates 22, four second linear modules 23 and four second pressing plates 24, the paper box conveying channel 10 corresponding to the bubble removing station is provided with an opening 11 for the paper box to pass through, the two first linear modules 21 are arranged above and below the opening 11 and are connected with the two first pressing plates 22 respectively, the four second linear modules 23 are arranged below the opening 11 and are arranged from the front, back, left and right four horizontal directions to face the opening 11, and the four second linear modules 23 are connected with the four second pressing plates 24 respectively. In this way, after the paper box enters the first pressing plate 22, the two first linear modules 21 drive the two first pressing plates 22 to press the paper box and pass through the opening 11 downward, then the four second linear modules 23 drive the four second pressing plates 24 to press and remove bubbles on the four sides of the paper box. After completion, the two first linear modules 21 drive the two first pressing plates 22 to press the paper box and pass through the opening 11 upward to reset.

[0064] The inner mold bubble removing process of the application has the following specific steps:

[0065] Firstly, the paper box is moved from the feeding area to the feeding station by the paper box taking mechanism 8, then the paper box is conveyed to the mold placing station by the moving mechanism 3, the position of the paper box on the paper box conveying channel 10 is corrected by the correcting mechanism 7, and then the following steps are executed:

[0066] S1, the lid is opened by the box opening mechanism 4;

[0067] S2, the inner mold S is placed in the lid by the mold taking mechanism 6;

[0068] S3, the lid is buckled on the lid by the box opening mechanism 4.
