DETAILED DESCRIPTION

[0023] 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.

[0024] In this embodiment, a three-grid carton forming machine, the shape of the carton board 1 is as follows: Figure 1 As shown, it is divided into three parts. In order to facilitate the subsequent folding into a three-grid paper box 8, four positioning holes 2 are provided in the middle for positioning, so as to facilitate the subsequent insertion of the insertion rod 502 for positioning. Figure 1 As shown, the forming machine specifically includes a frame 3, a feeding mechanism 4, a forming mechanism 5, and a discharging mechanism 6. The feeding mechanism 4 and the discharging mechanism 6 both adopt the mechanism of a single-grid paper box 8 or other paper box 8 forming machines. The feeding mechanism 4 is used to limit the structure of the paperboard 11. Those skilled in the art can make adaptive modifications with reference to different shapes of the paperboard 1, such as adding positioning rods as needed. The demoulding mold in the discharging mechanism 6 is made according to the internal structure of the three-grid paper box 8. The above modifications are modifications that can be made by those skilled in the art according to different shapes of the paper box 8, so they are not repeated in this embodiment.

[0025] In this embodiment, the molding mechanism 5 is mainly improved innovatively. Specifically, the molding mechanism 5 includes an upper mold 501, an insert rod 502, and a mold frame 503. Figure 5 , 6As shown, the upper mold 501 includes a top block 5011, a side module 5012, and a movable module 5013. Two side modules 5012 are symmetrically fixed at the lower end of the top block 5011. A movable module 5013 is arranged between the two side modules 5012. A triangular gap 5014 is formed between the two side modules 5012 and the movable module 5013. Folding plates and folding grooves are arranged on the side walls of the side modules 5012 and the movable module 5013 to facilitate the folding and forming of the paperboard 1. The shapes and sizes of the folding plates and folding grooves are set according to needs. Figure 3 , 4 As shown, the upper mold 501 is driven by a moving mechanism 1 to move in the vertical direction. The moving mechanism 1 includes a motor 504 fixed on the frame 3. The output shaft of the motor 504 is fixed to the center of the driving gear. The driving gear is meshed with a rack 506. The rack 506 is fixed on a moving frame 507. The moving frame 507 is slidably mounted on the frame 3. The lower end of the moving frame 507 is fixed to a top block 5011. The movable module 5013 is driven by a moving mechanism 2 to move in the vertical direction. The moving mechanism 2 includes a cylinder 1 508 fixed on the moving frame 507. The piston rod of the cylinder 1 508 is fixed to a moving rod 509. The moving rod 509 passes through the top block 5011 and is fixed to the movable module 5013. The top block 5011 is provided with a through hole 5015 for the moving rod 509 to pass through. The insert rods 502 are symmetrically arranged on both sides of the upper mold 501. The insert rods 502 are driven by the moving mechanism three to move in the vertical direction. The moving mechanism three includes a cylinder two 510 symmetrically fixed on the frame 3. The piston rod of the cylinder two 510 is fixed to the vertical rod 511. The two vertical rods 511 are connected by a connecting frame 512. The insert rods 502 are fixed to the lower end of the connecting frame 512. Two insert rods 502 are fixed to the lower end of each connecting frame 512.

[0026] The mold frame 503 is arranged below the upper mold 501. Figure 8 As shown, the upper and lower ends of the mold frame 503 are both open structures. Figure 7 As shown, the mold frame 503 is symmetrically provided with supporting plates 513 that can move vertically in the mold frame 503. Specifically, the supporting plates 513 can be lifted and lowered by adopting the following structure. The supporting plates 513 are respectively fixed on the supporting columns. The supporting columns are provided with springs. When the upper mold rises, the spring mechanism quickly resets, thereby realizing the movement of the supporting plates 513. A lower forming mold 514 that can move vertically is provided in the mold frame 503 and between the supporting plates 513. The lower forming mold 514 adopts the structure described in the moving mechanism 1 to achieve lifting and lowering. The gear is driven by the motor to rotate, and the gear drives the rack to move. The upper end of the rack is fixed with a mounting plate, and the mounting plate is driven by a connecting rod to move in the vertical direction. The supporting column is fixed on the mounting plate. Two triangular forming plates 505 are symmetrically fixed on the upper end of the lower forming mold 514, and the triangular forming plates 505 are adapted to the triangular gap 5014.

[0027] like Figure 1 As shown, it also includes an ultrasonic welding mechanism 7, which is arranged on both sides of the mold frame 503 and is used to weld the folded paper box 8. The ultrasonic welding mechanism 7 is an existing mechanism and will not be described in detail here.

[0028] Working principle: The initial state of the support plate 513 is flush with the upper end surface of the mold frame 503, and the triangular forming plate 505 is slightly lower than the support plate 513. The cardboard 1 is fed by the feeding mechanism 4. When the cardboard 1 moves to the support plate 513, the lower forming die 514 and the two triangular forming plates 505 move upward at the same time. The triangular forming plates 505 lift the cardboard 1 upward, and the cylinder 1 508 drives the movable module 5013 to move downward. The movable module 5013 presses the middle cardboard 1 into the groove formed by the two triangular forming plates 505 and the lower forming die 514. The movable module 5013 and the lower forming die 514 move downward at the same time until the upper end surface of the lower forming die 514 is flush with the upper end surface of the support plate 513, and the cylinder 2 510 drives the insertion rod 502 to move downward and insert it into the positioning hole 2 of the cardboard 1. At the same time, the moving mechanism 1 drives the side module 5012 to move downward until the lower end surface of the side module 5012 fits the upper end surface of the cardboard 1. Before the side module 5012 is fitted with the upper end surface of the cardboard 1, the cylinder 508 is used to ensure that the movable middle module 5013 does not move at this time. After the lower end surface of the side module 5012 is fitted with the upper end surface of the cardboard 1, the moving mechanism 1 is used to drive the side module 5012 and the movable module 5013 to move downward together, and at the same time, the lower forming mold 513 and the triangular forming plate 505 are moved downward together, so that the cardboard 1 completely enters the mold frame 503, and the upper mold 501 and the lower forming mold 513 and the mold frame 503 are used to form the outer frame of the paper box 8, and the triangular forming plate 505 and the triangular gap 5014 are used to form the partition inside the paper box 8. Then, the ultrasonic welding mechanism 7 is used to weld the paper box 8 after the folding. The lower part of the three-grid paper box 8 after folding is as shown in FIG. Fig. 9 The figure shows that the upper part of the three-grid paper box 8 is not shown. The triangular forming plate 505 and the upper mold 501 are reset, and the supporting plate 513 is moved upward by the spring mechanism, so that the formed paper box 8 is located above the mold frame 503, and the paper box 8 is moved to the discharge mechanism 6, and the folded three-grid paper box 8 is discharged by the discharge mechanism 6.
