DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In this embodiment, a double-grid carton forming machine, the shape of the carton board 1 is as follows: Figure 7 As shown, a positioning hole 2 is provided in the middle thereof for locating, so as to facilitate the subsequent insertion of the limiting rod 602. Figure 1 As shown, the double-grid paper box forming machine includes a frame 4, a feeding mechanism 5, a forming mechanism 6, and a discharging mechanism 7. The feeding mechanism 5 and the discharging mechanism 7 both adopt the mechanism of a single-grid paper box 3 or a paper box 3 forming machine. The feeding mechanism 5 is used for limiting the structure of the paperboard 1. Those skilled in the art can make adaptive modifications with reference to different shapes of the paperboard 1. The demoulding mold in the discharging mechanism 7 is made according to the internal structure of the double-grid paper box. The above modifications are modifications that can be made by those skilled in the art according to different shapes of the paper box, and therefore, they will not be repeated in this embodiment.

[0023] In this embodiment, the molding mechanism 6 is mainly improved innovatively. Specifically, the molding mechanism 6 includes an upper mold 601, a limiting rod 602, and a mold frame 603. Figure 2 As shown, the upper mold 601 is driven by the lifting mechanism 1 to move in the vertical direction. The lifting mechanism 1 includes a motor 604 fixed on the frame 4. The output shaft of the motor 604 is fixed to the center of the gear 605. The gear 605 is meshed with the rack 606. The rack 606 is movably mounted on the slide rail 607. The slide rail 607 is fixed on the frame 4. The upper mold 601 is mounted at the lower end of the rack 606. Figure 4 As shown, the upper mold 601 is in the shape of an inverted wedge, and the upper mold 601 is adapted to the inner wall of the paper box 3. A triangular groove 608 is provided at the lower end of the upper mold 601. The outer periphery of the upper mold 601 is provided with a folding plate and a folding groove at a corresponding position according to the shape of the paper box to facilitate the folding of the paperboard 1. The shape and size of the folding plate and the folding groove are set according to the needs. Figure 3 As shown, the limiting rods 602 are respectively arranged on both sides of the upper mold 601, and the limiting rods 602 are driven by the lifting mechanism 2 to move in the vertical direction. The lifting mechanism 2 includes a cylinder 609 fixed on the frame 4, the piston rod of the cylinder 609 is fixed to the moving rod 610, and the lower end of the moving rod 610 is fixed to the limiting rod 602, and the limiting rod 602 is L-shaped. The mold frame 603 is arranged below the upper mold 601, as shown in FIG. Figure 5As shown, the upper and lower ends of the mold frame 603 are both open structures. Two supporting plates 611 are arranged in the mold frame 603. The two supporting plates 611 can move up and down in the mold frame 603. The supporting plates 611 are driven by a cylinder to move in the vertical direction. A triangular forming plate 612 that can move up and down is arranged between the two supporting plates 611. The triangular forming plate 612 is adapted to the triangular groove 608. The specific structure is as follows: Figure 6 The moving mechanism of the triangular forming plate 612 is the same as the lifting mechanism 1, both of which are driven by a motor to rotate the gear, the gear drives the rack to move, and then the rack drives the triangular forming plate 612 to move in the vertical direction.

[0024] The mold frame 603 also includes an ultrasonic welding mechanism 8, which is arranged on both sides of the mold frame 603 and is used to weld the folded paper box 3. The ultrasonic welding mechanism 8 is an existing mechanism and will not be described in detail here.

[0025] Working principle: The support plate 611 is initially flush with the upper end surface of the mold frame 603, and the triangular forming plate 612 is slightly lower than the support plate 611. The cardboard 1 is fed by the feeding mechanism 5. When the cardboard 1 moves onto the support plate 611, the limiting rod 602 is inserted into the positioning hole 2 of the cardboard 1 by the lifting mechanism 2, and the upper mold 601 is moved downward by the lifting mechanism 1. After the lower mold contacts the cardboard 1, the lower mold and the support plate 611 move downward together. Under the action of the mold frame 603 and the upper mold 601, the cardboard 1 is folded and formed on all sides. Under the action of the triangular forming plate 612 and the triangular groove 608, the middle part of the cardboard 1 bulges upward and folds, and a partition is formed in the middle. Then the folded paper box 3 is welded and formed by the ultrasonic welding mechanism 8. The lower part of the double-grid paper box 3 after folding is as shown in FIG. Figure 8 The figure shows that the upper part of the double-grid paper box 3 is not shown. The supporting plate 611 and the triangular forming plate 612 are moved upwards, so that the formed paper box 3 is located above the mold frame 603, the triangular forming plate 612 is reset, and the paper box 3 is moved to the discharge mechanism 7, and the discharge mechanism 7 is used to discharge the folded double-grid paper box 3.
