Description

Technical Field

[0001] This utility model relates to the field of cardboard box production, and more specifically, to a cutting device for cardboard box production. Background Technology

[0002] In modern packaging production, cardboard boxes serve as an important carrier for logistics, warehousing, and product protection, leading to increasingly higher requirements for production efficiency and quality. Cutting equipment for cardboard box production has emerged as a key component in achieving efficient and precise cardboard box production.

[0003] The prior art disclosed in patent publication (announcement) number CN218558087U is a cutting device for carton production, including a base, on which supports are symmetrically arranged, and a placement platform for placing cartons is integrally connected to the base. A motor is fixedly installed on the supports, and a first lead screw is fixedly connected to the output end of the motor. A second lead screw is rotatably installed on the supports and is driven by the first lead screw. Matching nuts are symmetrically arranged on the first and second lead screws. Each nut is connected to a connecting rod, and the hinge points of the two connecting rods are connected to a fixing plate that moves against the cartons.

[0004] The aforementioned patent document discloses a cutting device for cardboard box production. While it can solve the problem of displacement or overturning during cutting caused by manual support, posing a certain safety hazard to operators, the lack of fixed limiting mechanisms often results in uneven cuts after cutting, leading to waste of cardboard resources and severely impacting cutting efficiency. However, its shortcomings are:

[0005] When the above device is in use, the cutter acts directly on the cardboard box, which will result in a large instantaneous impact force between the cutter and the cardboard box, which can easily damage the cutter or the cardboard box. It may also cause vibration and noise to the equipment itself, affecting the stability and lifespan of the equipment.

[0006] Furthermore, the cutting blades of this equipment are installed at the bottom of the guide plate, which makes the blade replacement inconvenient. Multiple parts need to be disassembled when replacement is required, which is cumbersome and time-consuming. This not only reduces production efficiency and increases maintenance difficulty, but may also lead to equipment failure or safety hazards due to improper operation during frequent replacement.

[0007] Therefore, we have made improvements to this and proposed a cutting device for cardboard box production. Utility Model Content
