Problems solved by technology

[0002] Currently on the market, in the process of laser cutting thinner paper, the paper will be curled and curled due to uneven heating of the cutting edge or due to the gas ejected during the cutting process or the smoke filtering and suction process. The paper will cover the paper that has not been cut, causing the paper to be cut unevenly
The traditional method is to fix the paper on the carrier board with glue, but the glue will be heated by the laser to produce an unpleasant smell, pollute the air, and damage people's health

Embodiment 1

[0017] Embodiment 1: A method for preventing curling in the paper cutting process, which is used in paper cutting equipment, is characterized in that, before cutting, the image to be cut 10 is introduced into the paper cutting equipment, and the circumference of the image to be cut 10 is set There are cutting breakpoints 11, and after the cutting is completed, the product and the original paper 20 remain partially connected through the cutting breakpoints 11.

[0018] see figure 1 , in this embodiment, the image to be cut 10 is a quadrilateral, and there are four cutting breakpoints 11, which are located at the four corners of the image to be cut 10 respectively.

[0019] The paper cutting equipment utilizes the Harris algorithm in OpenCV to identify the corner points of the image to be cut 10, after the recognition is completed, start cutting, and when the cutting device of the paper cutting equipment passes through the cutting breakpoint 11, stop Cutting, after passing thro...

Embodiment 2

[0020] Embodiment 2: The difference from Embodiment 1 is that when the cutting device of the paper cutting device passes through the cutting breakpoint 11, the cutting power is reduced so that the corners cannot be cut, and the product is kept connected to a part of the original paper 20, After passing through the cutting breaking point 11, the initial cutting power is restored.

Embodiment 3

[0021] Embodiment 3: The difference from Embodiment 1 is that when the cutting device of the paper cutting device passes through the cutting breakpoint 11, the walking speed of the cutting device is accelerated, so that the corners cannot be cut, and the product and the original paper 20 are retained. A part of the connection returns to the initial cutting speed after passing through the cutting breaking point 11 .

[0022] In summary, compared with the prior art, the present invention proposes a method for preventing curling during paper cutting. In the cutting process, the retained product is always connected with the original paper at multiple points. Through each connection point, the product is During the cutting process, it can maintain a flat state, which overcomes the defect of paper curling caused by traditional paper cutting.

Abstract

The invention provides a method for preventing curling in the paper cutting process, which is used in paper cutting equipment. Before cutting, an image to be cut is introduced into the paper cutting equipment, and a cutting breakpoint is arranged around the image to be cut After the cutting is completed, the product and the original paper remain partially connected through the cutting breakpoints. Through each connection point, the product can be kept in a flat state during the cutting process, which overcomes the defect of paper curling caused by traditional paper cutting.

Description

technical field [0001] The invention relates to the technical field of paper cutting methods, in particular to a method for preventing curling during paper cutting. Background technique [0002] Currently on the market, in the process of laser cutting thinner paper, the paper will be curled and curled due to uneven heating of the cutting edge or due to the gas ejected during the cutting process or the smoke filtering and suction process. Paper that has not been cut will cover the paper that has not been cut, resulting in uneven cutting of the paper. The traditional method is to fix the paper on the carrier board with glue, but the glue will be heated by the laser to produce unpleasant smell, pollute the air and damage people's health. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for preventing paper from curling during cutting, which is used for paper cutting equipment, and is characterized in t...
