[0049] A centralized storage mechanism 7 is provided at one end of the bottom of the main support member 12. The centralized storage mechanism 7 includes a storage box 71 and a blocking member 72. The storage box 71 is used for centralized storage of scrap materials. The blocking member 72 is used to connect with the first connecting member 33 to push the sealing member 32 out of the conveying member 31 so as to complete the discharge of scrap materials inside the conveying member 31 into the storage box 71.

There are two blocking members 72, which are movably connected to the top of the storage box 71 and can slide on the top of the storage box 71 according to the movement of the conveying member 31.

[0051] The working principle of the corrugated cardboard box cutting component provided by this utility model is as follows:

[0052] First, the second driving component 62 is activated to drive the second transmission component 61 to move. The second connecting component 63 then drives the two conveying components 31 to move towards or relative to each other. During this process, the two conveying components 31 drive the two supporting components 21 to move synchronously until the distance between the two limiting plates 41 is the width of the carton. Then, one end of the carton is placed against the first positioning component 13, and both sides of one end are connected to the two second positioning components 23 for top positioning. Subsequently, the first driving component 52 is activated to drive the first transmission component 51 to move. The moving frame 53 then drives the conveying component 31 to move towards the first positioning component 13. During the movement, the limiting plates 41 limit the two ends of the carton. Under the force of the third elastic component 44, the limiting is achieved. The component 43 is connected to the top of the carton to clamp it and prevent it from tilting. The cutting component 42 rotates at a high speed to cut the two sides of the carton. The cut scraps fall into the inside of the conveyor 31. When the first connecting component 33 is connected to the blocking component 72, the blocking component 72 provides a forward resistance to the first connecting component 33, and the conveyor 31 continues to move forward. As a result, the sealing component 32 is disengaged from the bottom of the conveyor 31, and the scraps fall into the storage box 71 through the bottom of the conveyor 31. The limiting plate 41 is connected to the second positioning component 23, which provides a forward thrust to the second positioning component 23, pushing it forward until the cutting component 42 completes the cutting of the carton.

[0053] Compared with related technologies, the corrugated cardboard box cutting assembly provided by this utility model has the following advantages:

[0054] Beneficial effects:

[0055] This utility model provides a corrugated cardboard box edge cutting assembly. The front-to-back drive mechanism 5 and the left-to-right drive mechanism 6 can drive the scrap material conveying mechanism 3 to move back-to-back and left-to-right to cut the edges of the cardboard box. At the same time, the first support and positioning mechanism 1 and the second support and positioning mechanism 2 support and position the cardboard box. The scrap material cut by the cutting part 42 falls into the conveying part 31. When it reaches the top of the storage box 71, the scrap material can be discharged into the storage box 71 for centralized storage. This device does not require manual cleaning of scrap material. It automatically collects scrap material during the cutting process, saving manpower and improving efficiency.
