[0010] With the above technical solution, when in use, the cardboard clamps the A area of the cardboard on the mold through the clamping member, and then the first driving member in the B area drives the folding member in the B area to rise. At this time, the inclined first abutting frame will first contact with the B area of the cardboard, thereby supporting the cardboard, and through the inclined setting, it has a buffering contact effect. Further, the first folding roller contacts the B area of the cardboard, so that it is folded on the mold. Further, when the first driving member in the B area drives the first abutting frame to rise to the position of the D area of the cardboard, further rise can drive the D area of the cardboard to be folded on the mold, and through the inclined first abutting frame, it has a buffering effect instead of hard collision and hard push, which can fully prevent the cardboard connection from breaking. Further, through the second driving member in the B area, the folding member in the B area is driven to extend, so that the D area of the cardboard can be better fitted to the mold. At the same time, the first driving member in the C area drives the folding member in the C area to rise, so that the inclined second abutting frame contacts with the C area of the cardboard, and forms a buffering effect through the inclined setting. Further, the second folding roller contacts the C area of the cardboard to fold it on the mold, thereby realizing the folding of the inner box.
[0011] The utility model is further configured as follows: the first folding roller is rotatably arranged at the bottom of the first abutting frame, and the second folding roller is rotatably arranged at the bottom of the second abutting frame.
[0012] By adopting the above technical solution, the cardboard can be prevented from being punctured by rolling, and the stability is better.
[0013] The utility model is further configured as follows: the first abutment frame and the second abutment frame include two separately arranged support plates and a connecting plate connected between the two support plates, and an abutment plate is also provided between the two support plates and at the top of both support plates, and the outer side of the abutment plate is arranged in an arc shape to form an abutment surface.
[0014] By adopting the above technical solution and the split setting, the difficulty of the processing technology can be simplified and it is also more convenient during assembly.
[0015] Further configuration of the utility model: a lifting platform in zone B is also provided on the frame, a second driving member in zone B is arranged on the lifting platform in zone B and rises and falls synchronously with the lifting platform, a folding member in zone B is arranged on the output end of the second driving member in zone B, and the first driving member in zone B includes a first-stage lifting driving member for driving the lifting platform to rise and fall in the first step and a second-stage lifting driving member for driving the lifting platform to rise and fall in the second step.
[0016] By adopting the above technical solution, a lifting platform is used for installation, which makes it more stable when in use, and enables the lifting platform in zone B to be lifted in two stages, and the first folding roller can be pressed down for trimming.
[0017] The utility model is further configured as follows: it also includes a C-zone lifting platform arranged on the output end of the first driving member of the C-zone, the C-zone folding member is arranged on the C-zone lifting platform, and the C-zone lifting platform is also provided with a C-zone second driving member for driving the C-zone folding member to extend and retract.
[0018] By adopting the above technical solution and using a lifting platform for installation, the folding member in zone C is more stable when being lifted or lowered, and the extension and retraction of the second driving member in zone C can drive the extension and retraction of the folding member in zone C, thereby achieving avoidance.
