Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, specifically a corrugated paper cutting device for corrugated cardboard box production. Background Technology

[0002] In the production of corrugated boxes, corrugated paper cutting is a key process, and its processing quality directly affects the quality of the finished boxes and production efficiency. In actual production, existing cutting equipment often suffers from unstable corrugated paper positioning and poor cutting accuracy, resulting in rough cuts. In addition, the paper dust generated during the cutting process not only pollutes the workshop environment, but also poses a risk to the health of operators and affects the normal operation of equipment.

[0003] Patent publication number "CN219947426U" discloses "This utility model relates to the field of corrugated cardboard box production technology, and discloses a cutting mechanism for corrugated cardboard box production, including a worktable, a limiting mechanism on the top surface of the worktable, and a cutting mechanism on the top surface of the worktable. An electric push rod pushes a connecting plate, which moves under the assistance of a limiting slider and a limiting groove. The connecting plate drives a push plate to move. The user can control a telescopic rod to push the limiting plate to adjust the distance between the limiting plate and the push plate, allowing the limiting plate to move inside the worktable, thereby adjusting the cutting length. This device can limit the corrugated cardboard box and accurately cut the required size of corrugated paper to suit the manufacture of corrugated cardboard boxes of different sizes. By opening a hydraulic rod, a telescopic drive shaft moves a lifting plate, which in turn moves a cutting blade downwards, allowing the cutting blade to cut the limited corrugated cardboard box, thus realizing the cutting adjustment function of the device."

[0004] In response to the aforementioned issues, existing corrugated cardboard cutting devices used in corrugated box production are prone to squeezing and deforming the corrugated cardboard during the pushing process. During the cutting process, dust and debris are easily generated, polluting the surrounding environment. When the corrugated cardboard is subjected to the cutting force of the blade during the cutting process, the cardboard may shift or warp, resulting in uneven cuts.

[0005] To address these issues, this invention provides a corrugated paper cutting device for corrugated box production. Utility Model Content

[0014] Beneficial effects

[0015] This utility model provides a corrugated paper cutting device for corrugated cardboard box production. Compared with the prior art, it has the following advantages:

[0016] 1. This corrugated paper cutting device uses a cutting component to allow a silicone pressure plate to flexibly press and fix the corrugated paper, effectively preventing paper displacement during the cutting process. In subsequent cutting processes, it ensures precise cutting, which not only improves cutting accuracy but also ensures neat cutting edges, reduces scrap rate, and guarantees the quality of corrugated box production.

[0017] 2. This corrugated paper cutting device uses an exhaust pump to ensure that paper scraps generated during the cutting process are promptly sucked into the exhaust cabinet, filtered by a filter screen, and then discharged. This maintains a clean working environment, reduces the risk of equipment failure caused by debris accumulation, and also reduces the frequency and intensity of manual cleaning, thereby improving the reliability of the equipment and the continuity of operation.

Then, the second motor 6 is started, its motor shaft drives the roller 18 to rotate, thus rotating the conveyor belt 4. The corrugated paper is placed on the conveyor belt 4 for transport. When the corrugated paper reaches the cutting position, the electric push rod 81 is activated, its output end pushing the connecting plate 82 downwards along the slide rod 7 until the silicone pressure plate 85 contacts the surface of the corrugated paper. At this point, the spring 83 is compressed, the telescopic rod 84 retracts, and the cutting blade 86 continues downwards to complete the cutting. After the action, the electric push rod 81 drives the connecting plate 82 to move up and reset. During the cutting process, the exhaust pump 14 is started, and a negative pressure is formed in the exhaust cabinet 12, so that the suction pipe 11 sucks up the cutting debris through the strip-shaped suction groove 10. The debris is discharged after being filtered by the filter screen 23. After the work is finished, the cabinet door 13 can be opened to clean the exhaust cabinet 12. The cut cardboard falls into the collection box 16 in the collection box 17 under the rotation of the fixed conveyor roller 15. After the work is finished, the collection box 16 can be pulled out for material discharge. The long support leg 21 and the short support leg 24 play the role of stabilizing and supporting the workbench 1.
