Description

Technical Field

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

[0002] Laser cutting uses a high-power density laser beam to focus on the focal position to generate high temperature.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1: Reference Figure 1-Figure 3 A paper laser cutting machine for paper production includes a workbench 1, a gantry 2 is fixedly connected to the workbench 1, a track 3 is fixedly connected to the gantry 2, a sliding seat 4 is slidably matched to the track 3, a first shell 6 is fixedly connected to the sliding seat 4, a laser 5 is fixedly connected to the top of the first shell 6, a first reflector 601 is fixedly connected to the first shell 6, an optical path channel 7 is fixedly connected to the side wall of the first shell 6, a second shell 8 is fixedly connected to the optical path channel 7, and a second reflector 801 is fixedly connected to the second shell 8;

[0025] When the device cuts the paper 101, the paper 101 is laid flat on the workbench 1 and then the laser 5 is started. The light emitted by the laser 5 is first reflected by the first reflector 601, and the reflected light enters the second shell 8 after passing through the optical path channel 7. The light entering the second shell 8 is refracted by the second reflector 801 and then emitted vertically downward.

[0026] like Figure 3-Figure 5 As shown, a connecting pipe 9 is fixedly connected to the bottom of the second shell 8, a pipe fitting 14 is rotatably installed at the bottom of the connecting pipe 9, a nozzle 16 is fixedly connected to the bottom of the pipe fitting 14, an air pipe 17 is fixedly connected to one side of the pipe fitting 14, a guide block 18 is fixedly connected to the other side of the pipe fitting 14, a slide rail 19 is slidably matched on the guide block 18, a connecting piece 20 is fixedly connected to the bottom of the slide rail 19, a roller 29 is rotatably installed on the connecting piece 20, a ring-shaped sponge strip 30 is fixedly connected to the surface of the roller 29, and a dropper 31 is fixedly connected to the connecting piece 20 to drip clean water on the sponge strip 30.

[0027] The light vertically emitted from the second shell 8 is emitted along the axis of the connecting tube 9, the tube 14 and the nozzle 16 to the paper 101 on the workbench 1, thereby cutting the paper 101. During the cutting process, the sliding seat 4 moves horizontally along the track 3 to drive the light to scan the paper 101, thereby completing the cutting work.

[0028] During the cutting process of the paper 101, the light inputs high-pressure airflow to the air pipe 17 through the hose, and the high-pressure airflow is emitted vertically downward from the nozzle 16, so as to clean the smoke generated by high temperature during the cutting process of the paper 101 and the ashes attached to the cut.

[0029] Secondly, during the process of cutting the paper 101, the light transports clean water to the dropper 31 through the hose. After flowing out of the dropper 31, the clean water will drip on the sponge bar 30 and be absorbed by the sponge bar 30. During the horizontal displacement of the sliding seat 4 along the track 3, the bottom of the sponge bar 30 is pressed on the paper 101 and rolls on the paper 101. An interaction force is generated between the paper 101 and the sponge bar 30. Under the action of the force, the moisture in the sponge bar 30 will be squeezed out of the part where the sponge bar 30 contacts the paper 101 and the paper is wetted.

[0030] Since the sponge bar 30 is located in front of the cutting track of the paper 101, the sponge bar 30 can wet the paper 101 in advance along the cutting track, and use the moisture to cool the paper 101 on both sides of the cut, thereby preventing the cut of the paper 101 from being oxidized significantly due to excessive temperature, and reducing the scorched marks caused by high temperature at the cut of the paper 101.

[0031] Embodiment 2: Figure 7 and Figure 8As shown, the connecting pipe 9 is provided with a driving structure to drive the pipe 14 to rotate, and the driving structure includes a first annular ring 10, the first ring 10 is fixedly connected to the connecting pipe 9, a motor 12 is fixedly connected to the outer ring of the first ring 10, a driving wheel 13 is fixedly connected to the output shaft of the motor 12, and a driven wheel 15 is fixedly connected to the pipe 14, and the driving wheel 13 cooperates with the driven wheel 15.

[0032] During the back and forth movement of the sliding seat 4 on the track 3, the laser emitted by the laser 5 will cut the paper 101. To ensure that the sponge bar 30 can also be located in front of the cutting track when the sliding seat 4 returns, the present invention uses a motor 12 to drive the sponge bar 30 to rotate around the axis of the nozzle 16. The working process is as follows:

[0033] When the paper 101 is cut and returns, the motor 12 starts and drives the driving wheel 13 to rotate, and the driving wheel 13 drives the driven wheel 15 to rotate. Since the driven wheel 15 is fixed on the pipe 14, the driven wheel 15 will drive the pipe 14 to rotate, and the rotation of the pipe 14 will drive the guide block 18 to rotate, and the guide block 18 will drive the slide rail 19 to rotate. During the rotation of the slide rail 19, the sponge bar 30 will be driven to rotate around the axis of the nozzle 16 through the connecting piece 20. When the sponge bar 30 rotates 180 degrees, the motor 12 stops working. At this time, the sponge bar 30 will be located in front of the return trajectory to wet the front of the cutting trajectory during the return process.

[0034] like Figure 7-Figure 9 As shown, a circular second ring member 11 is rotatably mounted on the connecting pipe 9, the second ring member 11 is located above the first ring member 10, the first ring member 10 is provided with two wedge-shaped grooves 32, the two wedge-shaped grooves 32 are located on the same diameter of the first ring member 10, the second ring member 11 is fixed with two wedge blocks 33, the two wedge blocks 33 are located on the same diameter of the second ring member 11, the wedge blocks 33 are slidably matched with the wedge grooves 32, and the slide rail 19 is fixed to the second ring member 11.

[0035] In the initial state, the wedge block 33 is located in the wedge groove 32 due to gravity. At this time, the sponge bar 30 can contact the paper. In order to prevent the sponge bar 30 from contacting the paper 101 during the process of rotating 180 degrees around the axis of the nozzle 16, the second ring member 11 will also rotate during the rotation of the slide rail 19. During the rotation of the second ring member 11, the wedge block 33 will move from the lowest point to the highest point of the wedge groove 32. During this process, the wedge block 33 will drive the second ring member 11 to move upward, the second ring member 11 will drive the slide rail 19 to move upward, and the slide rail 19 will drive the sponge bar 30 to move upward through the connecting member 20, so that the bottom of the sponge bar 30 cannot contact the paper 101 or the workbench 1. After the sponge bar 30 rotates 180 degrees around the axis of the nozzle 16, the wedge block 33 will rotate 180 degrees and fall back into the wedge groove 32 under the action of gravity, so that the sponge bar 30 moves down to be able to contact the paper 101.

[0036] Embodiment 3: Figure 5 and Figure 6 As shown, a thin-walled rotating body 25 is fixedly connected to the connecting member 20, and the axis of the rotating body 25 is parallel to the roller 29. An opening is provided on the top of the rotating body 25, and a circular ring 26 is rotatably installed on the rotating body 25. A plurality of support rods 27 are axially fixedly connected to the rotating ring 26. The plurality of support rods 27 are distributed circumferentially, and the center of the circle where the support rods 27 are located is located on the axis of the rotating body 25. An annular absorbent cotton strip 28 is sleeved on the outer side of the support rods 27. A slide groove 21 is provided on the connecting member 20, and a slider 22 is slidably matched in the slide groove 21. An extrusion wheel 24 is rotatably installed on the slider 22. A compression spring 23 is vertically fixedly connected to the connecting member 20, and the compression spring 23 applies elastic force to the slider 22 to make the extrusion wheel 24 press against the absorbent cotton strip 28.

[0037] When the sponge strip 30 rolls on the paper 101 , the absorbent cotton strip 28 also rolls on the paper 101 .

[0038] Viewed along the forward direction of the cutting track, the absorbent cotton strip 28 is located behind the sponge strip 30. After the sponge strip 30 wets the cutting track, the absorbent cotton strip 28 located behind the sponge strip 30 will clean the residual water stains on the cutting track to prevent the residual water on the surface of the paper 101 from refracting the laser light.

[0039] After the absorbent cotton strip 28 absorbs moisture, during the rolling process, the squeezing wheel 24 will apply downward pressure to the absorbent cotton strip 28 under the elastic force of the compression spring 23, thereby squeezing and drying the moisture in the absorbent cotton strip 28. The moisture squeezed out by the squeezing wheel 24 will fall into the interior of the rotating body 25 from the opening at the top of the rotating body 25 under the action of gravity for collection.

[0040] Working principle and workflow:

[0041] When cutting the paper 101, the paper 101 is laid flat on the workbench 1 and then the laser 5 is started. The light emitted by the laser 5 is first reflected by the first reflector 601, and the reflected light enters the second shell 8 after passing through the optical path channel 7. The light entering the second shell 8 is refracted by the second reflector 801 and then emitted vertically downward.

[0042] The light vertically emitted from the second shell 8 is emitted along the axis of the connecting tube 9, the tube 14 and the nozzle 16 to the paper 101 on the workbench 1, thereby cutting the paper 101. During the cutting process, the sliding seat 4 moves horizontally along the track 3 to drive the light to scan the paper 101, thereby completing the cutting work.

[0043] During the cutting process of the paper 101, the light inputs high-pressure airflow to the air pipe 17 through the hose, and the high-pressure airflow is emitted vertically downward from the nozzle 16, so as to clean the smoke generated by high temperature during the cutting process of the paper 101 and the ashes attached to the cut.

[0044] During the process of cutting the paper 101, the light transmits clean water to the dropper 31 through the hose. After flowing out of the dropper 31, the clean water will drip on the sponge bar 30 and be absorbed by the sponge bar 30. During the horizontal displacement of the sliding seat 4 along the track 3, the bottom of the sponge bar 30 is pressed on the paper 101 and rolls on the paper 101. An interaction force is generated between the paper 101 and the sponge bar 30. Under the action of the force, the moisture in the sponge bar 30 will be squeezed out of the part where the sponge bar 30 contacts the paper 101 and the paper is wetted.

[0045] Since the sponge bar 30 is located in front of the cutting track of the paper 101, the sponge bar 30 can wet the paper 101 in advance along the cutting track, and use the moisture to cool the paper 101 on both sides of the cut, thereby preventing the cut of the paper 101 from being oxidized significantly due to excessive temperature, and reducing the scorched marks caused by high temperature at the cut of the paper 101.

[0046] When the sponge bar 30 rolls on the paper 101, the absorbent cotton strip 28 also rolls on the paper 101. Viewed from the forward direction of the cutting track, the absorbent cotton strip 28 is located behind the sponge bar 30. After the sponge bar 30 wets the cutting track, the absorbent cotton strip 28 behind the sponge bar 30 will clean the residual water stains on the cutting track to prevent the residual water on the surface of the paper 101 from refracting the laser light.

[0047] After the absorbent cotton strip 28 absorbs moisture, during the rolling process, the squeezing wheel 24 will apply downward pressure to the absorbent cotton strip 28 under the elastic force of the compression spring 23, thereby squeezing and drying the moisture in the absorbent cotton strip 28. The moisture squeezed out by the squeezing wheel 24 will fall into the interior of the rotating body 25 from the opening at the top of the rotating body 25 under the action of gravity for collection.

[0048] During the back and forth movement of the sliding seat 4 on the track 3, the laser emitted by the laser 5 will cut the paper 101. To ensure that the sponge bar 30 can also be located in front of the cutting track when the sliding seat 4 returns, the present invention uses a motor 12 to drive the sponge bar 30 to rotate around the axis of the nozzle 16. The working process is as follows:

[0049] When the paper 101 is cut and returns, the motor 12 starts and drives the driving wheel 13 to rotate, and the driving wheel 13 drives the driven wheel 15 to rotate. Since the driven wheel 15 is fixed on the pipe 14, the driven wheel 15 will drive the pipe 14 to rotate, and the rotation of the pipe 14 will drive the guide block 18 to rotate, and the guide block 18 will drive the slide rail 19 to rotate. During the rotation of the slide rail 19, the sponge bar 30 will be driven to rotate around the axis of the nozzle 16 through the connecting piece 20. When the sponge bar 30 rotates 180 degrees, the motor 12 stops working. At this time, the sponge bar 30 will be located in front of the return trajectory to wet the front of the cutting trajectory during the return process.

[0050] In the initial state, the wedge block 33 is located in the wedge groove 32 due to gravity. At this time, the sponge bar 30 can contact the paper. In order to prevent the sponge bar 30 from contacting the paper 101 during the process of rotating 180 degrees around the axis of the nozzle 16, the second ring member 11 will also rotate during the rotation of the slide rail 19. During the rotation of the second ring member 11, the wedge block 33 will move from the lowest point to the highest point of the wedge groove 32. During this process, the wedge block 33 will drive the second ring member 11 to move upward, the second ring member 11 will drive the slide rail 19 to move upward, and the slide rail 19 will drive the sponge bar 30 to move upward through the connecting member 20, so that the bottom of the sponge bar 30 cannot contact the paper 101 or the workbench 1. After the sponge bar 30 rotates 180 degrees around the axis of the nozzle 16, the wedge block 33 will rotate 180 degrees and fall back into the wedge groove 32 under the action of gravity, so that the sponge bar 30 moves down to be able to contact the paper 101.

[0051] Compared with the prior art, the laser cutting machine provided by the present invention can wet the paper along the cutting track in advance when cutting the paper 101, and use the moisture to cool the paper 101 on both sides of the cut, thereby preventing the cut of the paper 101 from being oxidized significantly due to excessive temperature, and reducing the scorched marks caused by high temperature at the cut of the paper 101.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
