Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly carton production, in particular to an environmentally friendly carton precision cutting device. Background Art

[0002] Environmentally friendly cartons refer to cartons whose manufacturing process complies with environmental standards, and whose products can be recycled or decomposed quickly by nature. The raw materials of environmentally friendly cartons are usually pulp, which does not contain toxic and harmful chemicals and will not cause negative impacts on people's health and the environment. With the improvement of environmental awareness, the application prospects of environmentally friendly cartons are very broad. In the future, environmentally friendly cartons may further optimize their design and materials to meet more diversified market demands. In order to improve the production efficiency of environmentally friendly cartons, a cutting device is needed. However, the existing cutting device still has the following shortcomings:

[0003] For example, the utility model with publication number CN217574265U discloses a cutting device for energy-saving and environmentally friendly cardboard processing. The utility model is provided with a bidirectional threaded rod, a crank and a support frame. The crank rotates the bidirectional threaded rod to adjust the spacing of the support frame. The tooth plate is fixedly connected to the support frame, so that the spacing of the tooth plate is adjusted. The tooth plate is fixedly connected to the cutting plate, so that the cutting plate drives the cutting blades to move closer or farther away from each other, so that the cutting device can cut cartons of different widths. However, similar to the comparative documents of the above-mentioned application, when the existing cutting device is used, since most cutting devices are not convenient for accurately positioning the cartons to be processed, the cartons are easily offset during the cutting process, which affects the yield rate of the carton processing, resulting in reduced practicality and reduced efficiency of the cutting device.
