Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] Example 1:

[0026] In this embodiment, as Figure 1-5As shown, this utility model proposes a mold for carton processing, including a base plate 1. The surface of the base plate is provided with a knife groove, and a blade 2 is embedded in the knife groove. Buffer blocks 3 are provided on both sides of the blade at intervals. The buffer blocks can increase the contact area with the carton cardboard, prevent the carton cardboard from sliding and affecting the processing quality, and limit the two ends of the blade to prevent the blade from being damaged or tilted. The area enclosed by the blade is a cutting cavity 4. Several retaining strips 5 are provided inside the cutting cavity. The bottom of the retaining strip is a fixing plate 51. The nail passes through the fixing plate to connect the retaining strip to the base plate. Both ends of the retaining strip abut against the blade to prevent the retaining strip from missing and forming a concave mark, which would affect the folding of the carton cardboard. The middle of the retaining strip is a convex strip 52. The convex strip is set vertically upward. The convex strip can leave a concave mark after the carton cardboard is squeezed by the extrusion roller, which facilitates the subsequent folding of the carton cardboard.

[0027] In this embodiment, the cutting cavity is further provided with a curved groove 6 on the outside. The end of the curved groove facing the cutting cavity is semi-circular, and the end of the curved groove away from the cutting cavity is open. A reinforcing strip 7 is fixedly provided in the curved groove. Since the blade is relatively thin at the curved groove and the precision requirement is high, the reinforcing strip is provided to prevent the blade from tilting during long-term use and affecting the processing quality.

[0028] In this embodiment, the cutting cavity area overlaps with the surface of the base plate, the area of ​​the cutting cavity area is smaller than the area of ​​the base plate, and the area of ​​the cardboard box is larger than the area of ​​the cutting cavity area.

[0029] A die-cutting machine includes a frame 8. A drive motor 9 is provided on one side of the frame. The output end of the drive motor 9 is connected to one end of a drive roller 10. The drive roller 10 is driven to rotate by the drive motor 9. A conveyor belt 11 is provided above the drive roller 1. A support platform 12 is provided below the middle of the conveyor belt 1. A mounting plate 13 is provided above the conveyor belt 1. A base plate is placed on the mounting plate. A drive motor 14 is provided on the other side of the frame. The output end of the drive motor 14 is connected to one end of a drive roller 15. The drive roller 15 is driven to rotate by the drive motor 14. A conveyor belt 16 is provided above the drive roller 1. A support platform 17 is provided below the middle of the conveyor belt 1.

[0030] In this embodiment, the frame is further configured such that a first extrusion roller 18 and a second extrusion roller 19 are provided in the middle of the frame. The first extrusion roller is located above the second extrusion roller. One end of the first extrusion roller is connected to the output end of the third drive motor 20, and the third drive motor drives the first extrusion roller to rotate. One end of the second extrusion roller is connected to the output end of the fourth drive motor 21, and the fourth drive motor drives the second extrusion roller to rotate.

[0031] In this embodiment, the compression roller 1 and compression roller 2 rotate in opposite directions, so that the mounting plate, mold and carton board are squeezed by compression roller 1 and compression roller 2 during the process of moving from conveyor belt 1 to transmission belt 2, thereby completing the cutting of carton board.

[0032] In this example, the drive roller 1, drive roller 2, and extrusion roller 1 rotate in the same direction. When rotating clockwise, the mounting plate is conveyed from above the conveyor belt 1 to above the transmission belt 2. When rotating counterclockwise, the mounting plate is conveyed from above the conveyor belt 2 to above the transmission belt 1.

[0033] In this embodiment, the surface of the extrusion roller is further covered with a buffer pad 22. The buffer pad can prevent the blade on the mounting plate from damaging the extrusion roller during the cutting process. At the same time, the buffer pad has a certain adjustment distance and can process cardboard boxes within a certain thickness range, making it more widely applicable. The buffer pad can be made of materials such as cotton cloth.

[0034] In this example, the highest point of the extrusion roller one coincides with the highest points of conveyor belt one and conveyor belt two, which enables the mounting plate to be smoothly conveyed from conveyor belt one through extrusion roller two onto conveyor belt two.

[0035] Example 2:

[0036] In this embodiment, as Figure 1-5 As shown, based on Embodiment 1, the buffer blocks spaced apart on both sides of the blade can be replaced by foam pads. The foam pads are placed on the path where the blade is set and connected by adhesive or nails. After being squeezed once by the extrusion rollers through the mold, the blade protrudes from the foam pads. Compared with the buffer blocks, the foam pads are easier to install. It is worth noting that the foam pads need to avoid the retaining strips to prevent the foam pads from covering the retaining strips and causing missing indentations or poor results.

[0037] The working principle of the mold and die-cutting machine used for carton processing is as follows: select the mold to be processed and place the mold on the mounting plate, then place the carton board that is larger than the bottom plate of the mold on the mold. The mounting plate, the mold and the carton board pass through the gap between the extrusion rollers 1 and 2 as they move from conveyor belt 1 to transmission belt 2. The carton board is cut during the extrusion process.
