[0035] The present invention provides a carton opening machine. Considering that the carton is usually a rectangular parallelepiped structure, the two longer side panels are usually sealed on the outside. If the pressure on the cardboard surface is relatively large, it is easy to damage the cardboard surface and cause unsightly appearance. It is also easy to puncture the cardboard when it encounters unexpected resistance. In order to prevent this phenomenon from happening, a lever 9 is installed on each of the two sealing arms 8. Figure 3 As shown, two shifting rods 9 are provided parallel to each other, so that when the fourth driving device 7 acts, the sealing arm 8 can drive the shifting rod 9 to bend the cardboard at the bottom of the box body.

[0036] The present invention provides a carton opening machine, which specifically provides a structural structure of a material receiving unit. Specifically, Figure 2 As shown, the material receiving unit includes two conveyor belts 22 arranged opposite to each other. The conveying surfaces of the two conveyor belts 22 are arranged opposite to each other, and the conveying directions of the conveying surfaces are in the same direction, which is used to gradually push the cartons placed between the two conveyor belts 22 forward. A feeding channel is formed between the two conveyor belts 22, and a tape sealing component is provided below the feeding channel. By setting up the sealing component, the cartons conveyed to this position can be directly glued, that is, the tape sealing operation is completed at the same time, which can further save labor costs. Specifically, the tape sealing component can be provided here to include a tape roller 14, a cutting mechanism 20 and two roller pressing rollers 19, as shown in FIG. Figure 9 and Figure 10 As shown, the tape roller 14 is used to supply the tape to be sealed to the bottom of the carton, the cutting mechanism 20 is used to cut the tape, and the pressing roller 19 is used to press the tape tightly on the bottom and side of the carton, wherein the two pressing rollers 19 can rotate through the linkage structure to make the tape attached to the side of the carton, according to Figure 9As shown, when sealing with tape, in addition to sealing the bottom surface, the tape also needs to be attached to the side of the carton to ensure the stability of the tape. At this time, by setting a roller 19 to rotate through the connecting structure, the tape can be pressed against the side of the carton to avoid the problem that the tape cannot be well adhered to the side of the carton after being pulled out.

[0037] The present invention provides a carton opening machine, which specifically provides a linkage structure. Specifically, the linkage structure includes a mounting plate 15 mounted inside the feeding channel and two connecting frames 16 hingedly mounted on the mounting plate 15.

[0038] The present invention provides a carton opening machine. In order to prevent the carton from falling from the open side of the storage rack 1 after being pushed by the push plate 2, the push plate 2 is slidably installed on the storage rack 1. The storage rack 1 is provided with a tension spring for connecting the push plate 2, which is used to provide an adaptive tension to tighten the carton on the storage rack 1. In order to prevent the carton from falling directly from the open side, a blocking mechanism 21 is further provided above the open side of the storage rack 1. The blocking mechanism 21 is used to resist the carton at the front end of the storage rack 1. As a preferred embodiment, the blocking mechanism 21 can be provided to include a limiter and an opening member installed at the front end of the limiter. The limiter is used to position the carton at the front end by friction, so that the carton can be tightened by friction after moving to this position. The opening member is used to guide the edge of the carton to the position of the limiter. After the carton is subjected to a suction force greater than the friction force, the carton is taken out from the position of the limiter and opened by the action of the unpacking guide rod 6. In order to save the tension of the tension spring and reduce the design requirements of the tension spring, the storage bracket 1 can be set to be inclined with respect to the horizontal plane, and the position height of the opening side of the storage bracket 1 can be set to be the lowest, so that the carton can tend to move toward the opening side under the action of gravity, thereby reducing the design requirements of the spring.
