Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting, in particular to a laser cutting device for paper production. Background Art

[0002] Laser cutting is a precision processing technology that uses a high-energy-density laser beam as an "invisible tool" to separate materials through light-heat-matter interaction. In the paper production process, various shapes of paper are often required to meet different customization requirements. Therefore, laser cutting is required to cut the paper into specific shapes.

[0003] Patent publication number CN214769738U discloses a paper laser cutting machine for cardboard production, relating to the technical field of laser cutting machines. Specifically, the machine comprises a machine tool, wherein longitudinal movement mechanisms are provided on the left and right sides of the top of the machine tool, a transverse movement mechanism is provided on top of the longitudinal movement mechanism, a movable block is provided on top of the transverse movement mechanism, a laser cutting head is fixedly mounted on the front of the movable block, and nitrogen nozzles are fixedly connected to both sides of the bottom of the laser cutting head. The paper laser cutting machine for cardboard production, by providing nitrogen nozzles, ejects nitrogen during the cutting process, isolating oxygen near the laser cutting head, preventing combustion when the laser cutting head cuts the cardboard, and facilitating the safety of the cardboard. A drag chain is provided on the outside of a first conveying pipe, facilitating the movement of the first conveying pipe along with the movable block, preventing entanglement of the first conveying pipe.

[0055] Specifically, in the prior art, when a plurality of sheets of paper of the same shape need to be cut from a complete sheet of paper, a collection container is usually used to collect the cut sheets of paper. However, when the sheets of paper are in the collection container, they tend to be in a messy pile, which is not only not conducive to subsequent transportation and retrieval, but also may cause the sheets of paper to fold due to the squeezing of the sheets of paper, thereby affecting the subsequent use of the sheets of paper.

[0056] Therefore, in order to solve the above problem, the working principle of this embodiment is as follows:

[0057] In some cases, in order to meet the needs of teaching aid production and personalized customization, equilateral triangle paper needs to be used. Therefore, multiple equilateral triangle papers need to be cut from a complete paper. The present embodiment works in response to this situation; according to the side length of the equilateral triangle to be cut, the motor 6 24 drives the connecting rod 1 25 to rotate, and the connecting rod 1 25 drives the connecting rod 2 26 to rotate, so that the limiting post 23 slides in the slide groove of the carrying plate 46. Since a 60-degree angle is set on one side of the limiting post 23, the angle of the three limiting posts 23 is regarded as one corner of the triangle, and the distance between two adjacent limiting posts 23 is the side length of the triangle. The orientation of the limiting post 23 can be adjusted according to the side length of the equilateral triangle paper to be cut, and adapted to the equilateral triangle paper;

[0058] By means of the motor 2 12 driving the threaded rod 3 13 to rotate and the motor 3 14 driving the threaded rod 2 11 to rotate, the position of the carrier plate 46 is adjusted, and the angle of the limit column 23 is aligned with the angle of the equilateral triangle paper to be cut, and then the tray 28 is driven to fit the bottom of the paper, and under the action of the air pump 29, the paper is adsorbed by the suction cup 42. After the laser cutting head 6 cuts an equilateral triangle on the paper, the motor 5 20 drives the threaded rod 4 22 to rotate to drive the tray 28 down, and the three corners of the equilateral triangle paper will move downward along the angle of the limit column 23. When the equilateral triangle paper falls to After the paper is properly positioned, the valve on the air inlet pipe 43 is opened to allow the suction cup 42 to release the equilateral triangle paper. Then, under the action of the cylinder 1 21, the tray 28 is driven to move away from the bottom of the equilateral triangle paper. The above operation is repeated to place all the cut equilateral triangle paper on the carrier plate 46. Under the action of the limiting pillar 23, the edges of all the equilateral triangle paper are aligned and stacked neatly, thereby avoiding the cut paper from being piled up in a mess in the container, which is not conducive to subsequent transportation and retrieval. In addition, it also avoids the situation where the paper is squeezed against each other and causes the paper to fold, which affects the subsequent use of the paper.

[0059] Although the above method can realize the neat stacking of the cut equilateral triangle paper, when the tray 28 is moved away from the bottom of the equilateral triangle paper, the equilateral triangle paper is prone to slip due to friction, resulting in bending, and the angle of the equilateral triangle paper is also prone to bending during the downward movement, resulting in folding of the angle, affecting subsequent use. Therefore, in order to solve the above problem, when the equilateral triangle paper drops to a certain position and before the tray 28 is moved away from the bottom of the equilateral triangle paper, according to the height of the equilateral triangle paper, the motor 8 48 is used to drive the threaded rod 5 30 to rotate, so as to adjust the height of the slider 31 so that the equilateral triangle paper is between the pulleys 35 on the upper and lower sides, and then the cylinder 2 32 is used to drive the slot plate 2 36 to move horizontally, so that the extension rod 34 and the pulley 35 pass through the strip through hole on the limit column 23, and the pulleys 35 on the upper and lower sides are separated. The upper and lower surfaces of the equilateral triangle paper are aligned, and then the motor 7 37 drives the bidirectional threaded rod 2 38 to rotate, driving the two pulleys 35 to approach the equilateral triangle paper and contact it. At the same time, under the action of the spring damper 40, the equilateral triangle paper can be pressed by the pulley 35, and then the tray 28 is driven away from the equilateral triangle paper. The equilateral triangle paper will not move due to being pressed, which avoids the equilateral triangle paper from slipping due to friction when the tray 28 is moved away from the bottom of the equilateral triangle paper. Then the pulley 35 is driven horizontally again and away from the angle of the equilateral triangle paper. The angle of the equilateral triangle paper will be flattened due to the horizontal movement of the pulley 35, and the flattened triangular paper will fall onto the triangular paper below, thereby avoiding the angle of the equilateral triangle paper from bending easily during the downward movement, which in turn causes the angle to fold and affect subsequent use.

[0060] Working principle: According to the size of the paper to be cut, the four corners of the paper are placed on the support block 17 respectively, and the electric push rod 19 drives the pressure plate 18 to press the paper tightly, and then the motor 17 drives the two-way threaded rod 3 8 to rotate, and the motor 4 15 drives the two-way threaded rod 16 to rotate, so that the support block 17 moves until the paper is flattened under the traction of the support block 17 and the pressure plate 18, and then the laser cutting head 6 is used to laser cut the paper through the cooperation of the moving mechanism 1 2, the moving mechanism 2 3, and the moving mechanism 3 5. The moving mechanism 1 2, the moving mechanism 2 3, and the moving mechanism 3 5 are existing guide rail displacement technologies, which will not be described in detail here. The cutting process In the process, since the paper is pressed and laid out flat, the stability of the paper and the accuracy of the cutting are guaranteed during the cutting process, which is conducive to improving the cutting effect. According to the side length of the equilateral triangle to be cut, the motor 6 24 drives the connecting rod 1 25 to rotate, and the connecting rod 1 25 drives the connecting rod 2 26 to rotate, so that the limiting post 23 slides in the slide groove of the carrying plate 46. Since a 60-degree angle is set on one side of the limiting post 23, the angle of the three limiting posts 23 is regarded as a corner of the triangle, and the distance between two adjacent limiting posts 23 is the side length of the triangle. The orientation of the limiting post 23 can be adjusted according to the side length of the equilateral triangle paper to be cut. Adjust and adapt to the equilateral triangle paper; the orientation of the carrier plate 46 is adjusted by driving the threaded rod three 13 to rotate by the motor two 12 and the threaded rod two 11 to rotate by the motor three 14, and the angle of the limit column 23 is aligned with the angle of the equilateral triangle paper to be cut, and then the tray 28 is driven to fit the bottom of the paper, and under the action of the air pump 29, the paper is adsorbed by the suction cup 42. After the laser cutting head 6 cuts an equilateral triangle on the paper, the tray 28 is driven down by driving the threaded rod four 22 to rotate by the motor five 20, and the triangles of the equilateral triangle paper will move downward along the angle of the limit column 23. When the equilateral triangle paper is cut out, the tray 28 is moved down along the angle of the limit column 23. After the triangular paper has fallen to a suitable position, the valve on the air inlet pipe 43 is opened to allow the suction cup 42 to release the equilateral triangle paper. Then, under the action of the cylinder 1 21, the tray 28 is driven to move away from the bottom of the equilateral triangle paper. The above operation is repeated, so that all the cut equilateral triangle papers are placed on the supporting plate 46. Under the action of the limiting pillars 23, the edges of all the equilateral triangle papers are aligned and stacked neatly, thereby avoiding the cut papers from being piled up in a messy manner in the container, which is not conducive to subsequent transportation and retrieval. In addition, it also avoids the situation where the papers are squeezed against each other and cause the papers to fold, which affects the subsequent use of the papers.Although the above method can realize the neat stacking of the cut equilateral triangle paper, when the tray 28 is moved away from the bottom of the equilateral triangle paper, the equilateral triangle paper is prone to slip due to friction, resulting in bending, and the angle of the equilateral triangle paper is also prone to bending during the downward movement, resulting in folding of the angle, affecting subsequent use. Therefore, in order to solve the above problem, when the equilateral triangle paper drops to a certain position and before the tray 28 is moved away from the bottom of the equilateral triangle paper, according to the height of the equilateral triangle paper, the motor 8 48 is used to drive the threaded rod 5 30 to rotate, so as to adjust the height of the slider 31 so that the equilateral triangle paper is between the pulleys 35 on the upper and lower sides, and then the cylinder 2 32 is used to drive the slot plate 2 36 to move horizontally, so that the extension rod 34 and the pulley 35 pass through the strip through hole on the limit column 23, and the pulleys 35 on the upper and lower sides are separated. The upper and lower surfaces of the equilateral triangle paper are aligned, and then the motor 7 37 drives the bidirectional threaded rod 2 38 to rotate, driving the two pulleys 35 to approach the equilateral triangle paper and contact it. At the same time, under the action of the spring damper 40, the equilateral triangle paper can be pressed by the pulley 35. Then the tray 28 is driven away from the equilateral triangle paper. The equilateral triangle paper will not move due to being pressed, which prevents the equilateral triangle paper from slipping due to friction when the tray 28 is moved away from the bottom of the equilateral triangle paper. Then the pulley 35 is driven horizontally again and away from the angle of the equilateral triangle paper. The angle of the equilateral triangle paper will be flattened due to the horizontal movement of the pulley 35. The flattened triangle paper will fall onto the triangle paper below, thereby preventing the angle of the equilateral triangle paper from bending easily during the downward movement, which will cause the angle to fold and affect subsequent use.
