Description

Technical Field

[0001] The invention relates to the field of corrugated paper box processing, and in particular to an indentation device for facilitating the folding of corrugated paper boxes. Background Art

[0002] With the rise of the express delivery industry, people's demand for packaging is also increasing. Corrugated boxes are gradually replacing wooden boxes and other transport packaging containers due to their superior performance and good processing performance. Corrugated boxes need to be folded before they are put into use. After the processing of the corrugated boxes is completed, the corrugated boxes need to be indented to facilitate the staff to fold the corrugated boxes later.

[0003] Most of the existing corrugated cardboard creasing devices require staff to place the corrugated cardboard box on the top of the device and then start the creasing device to creasing the corrugated cardboard box. However, the current devices require staff to manually fix the corrugated cardboard box. Manual fixation will result in low creasing efficiency and the position is prone to deviation, resulting in poor creasing effect. In addition, the corrugated cardboard box is prone to bulging when creasing, and further creasing it is likely to cause cracks in the gaps of the corrugated cardboard box. Summary of the invention

[0014] 2. The downward movement of the support frame will drive the pressing plate and the fixed block to move downward. When the pressing plate moves downward to contact the corrugated cardboard box to be folded, the corrugated cardboard box to be folded will resist the pressing plate. The fixed plate will continue to move downward to compress the return spring. The fixed plate will apply a downward force to the pressing plate through the return spring again, so that the pressing plate can press the middle part of the corrugated cardboard box to be folded, thereby reducing the possibility of bulging of the corrugated cardboard box during indentation, thereby making the indentation effect of the corrugated cardboard box to be folded better, which can further facilitate the subsequent staff to fold the cardboard boxes.

[0015] 3. The downward movement of the support frame will cause the roller to move downward. When the roller moves downward to contact the corrugated cardboard box to be folded, the corrugated cardboard box to be folded will resist the roller. The support frame continues to move downward to apply downward force to the cross pressure bar, spring sheet and roller again. The cross pressure bar can press both sides of the corrugated cardboard box to be folded, thereby effectively preventing the corrugated cardboard box to be folded from breaking during the subsequent indentation process, thereby protecting the corrugated cardboard box. When the cross pressure bar moves downward to contact the crease gap of the corrugated cardboard box, the cross pressure bar can press the crease gap of the corrugated cardboard box again, thereby improving the indentation effect of the corrugated cardboard box to be folded, thereby further facilitating the staff to fold the cardboard boxes later.

[0031] Embodiment 3: Based on embodiment 2, Figure 4 and Figure 7As shown, it also includes an anti-cracking edge component, which is used to reduce the possibility of the corrugated box to be folded from cracking.

The roller 84 will move upward to reset and drive the cross pressure rod 81 to reset. The support frame 52 will continue to move upward to reset and drive the cross pressure rod 81 to reset.

The upward movement and reset of the support frame 52 will drive the pressure strip 94 to reset. The upward movement and reset of the pressure strip 94 will no longer press the swing frame 92, and the swing frame 92 will reset under the action of gravity.
