[0002] With the rapid development of the packaging industry, composite paperboard, as an important packaging material, is being used more and more frequently in daily life. Multi-layer composite paperboard is mainly used in paper box processing and packaging. In the production process of composite paperboard, the cutting process is a crucial step. During the cutting process, large-sized composite paperboard often needs to be cut according to specific specifications to meet the needs of subsequent packaging, printing or other processing steps.

[0003] To ensure the accuracy of dimensional cutting, a paperboard conveying and positioning structure needs to be set in the cutting device. For the cutting and positioning of composite paperboard, existing cutting devices mostly adopt a positioning working structure of photoelectric induction combined with servo conveying. Although it can determine the edge position of the paperboard through induction and complete the cutting position control adjustment in conjunction with servo conveying, it is difficult to ensure the straightness of the paperboard during the positioning and conveying process. Once the paperboard is conveyed skewed, it will lead to the dimensional deviation between the waste board and the finished board. Therefore, a cutting device for composite paperboard production is proposed. Utility Model Content

[0036] Working principle or structural principle: During operation, the cardboard is fed into the cutting device from the front. The cardboard is driven and supported by the first guide roller 2 and moved above the guide support roller 3. Then, it is driven by the second guide roller 4 and moved backward towards the cutting side. At the same time, the positioning baffle 13 is driven by the baffle drive cylinder 12 to move downward. The positioning baffle 13 stops and supports the conveyed cardboard, achieving both cutting base alignment and correction of any deviation in the cardboard. Afterward, the positioning baffle 13 is driven upward by the baffle drive cylinder 12, and the cardboard is driven by the second guide roller 4 into the positioning conveyor roller 5. The positioning conveyor roller 5 moves backward a certain distance and then stops. Finally, the cutting drive cylinder 10 drives the cutting blade 1. 1. The cardboard is cut by moving downwards, and this cycle is repeated to achieve fixed-length cutting of the cardboard. The cut cardboard is then conveyed to the discharge plate seat 14. At this time, the flipping conveyor wheel 15 is pulled back by the flipping drive cylinder 18 and is in an upward lifting support state. The flipping conveyor wheel 15 supports and guides the board material to be received and supported on the upper part of the discharge plate seat 14. Then, the flipping drive cylinder 18 pushes the forward to make the flipping conveyor wheel 15 flip down and reset. At this time, the lower part of the board material contacts and supports the board material conveyor belt 20 protruding from the upper part of the discharge plate seat 14. Finally, the belt drive motor 22 drives the board material conveyor belt 20 to convey and discharge the received board material from the side. Stable receiving and discharge of the cut board material can be completed without manual assistance, which greatly improves the operation convenience of the device.

[0037] In summary, this cutting device adopts a baffle positioning combined with servo conveying cutting positioning structure. A positioning baffle 13 is installed on the cutting side of the cardboard via a baffle drive cylinder 12. During cardboard cutting, the downward-moving positioning baffle 13 stops and supports the end of the cardboard. This not only calibrates the cutting base position of the positioning baffle 13 but also corrects any deviation in the cardboard's position. Combined with the precise conveying of the rear positioning conveyor roller 5, this effectively improves the cutting positioning accuracy of the cardboard. Furthermore, it solves the problem of dimensional deviations between waste boards and finished boards caused by skewed cardboard conveying. The device employs a sloping plate and flip-wheel discharge structure. The discharge plate seat 14 receives the cut sheet metal, and a flip conveyor wheel 15 is installed on the upper part of the discharge plate seat 14. The flip conveyor wheel 15 is driven by a flip drive cylinder 18 and a drive linkage 17. When receiving the sheet metal, the flip conveyor wheel 15 flips up to support and receive the sheet metal. After receiving the sheet metal, the flip conveyor wheel 15 flips down to reset and the sheet metal is conveyed laterally through the sheet metal conveyor belt 20. The device can stably receive and discharge the cut sheet metal without manual assistance, which greatly improves the ease of operation.
