Description

Technical Field

[0001] The present invention belongs to the technical field of laser cutting, and in particular, relates to a laser cutting device, and more particularly to a laser cutting method. Background Art

[0002] Laser cutting utilizes a laser beam to cut fabric. This method allows for unfinished edges (no trimming or hemming). The latest fabric cutting technology utilizes a laser beam. Laser cutting is particularly advantageous for fabrics with high polyester or polyamide content, as the high temperature of the laser melts the edges, creating a seamless edge that won't unravel.

[0003] However, the laser cutting equipment in the prior art still has the following problems:

[0004] First, the wrinkle removal process of existing laser cutting equipment is relatively complicated. Before the cutting process, one or two people are often required to press and flatten the mask on the fabric. This process is time-consuming and labor-intensive, and reduces the efficiency of fabric cutting.

[0005] Second, when existing laser cutting equipment is cutting, some fabrics made of animal hair or fabrics with high polyester or polyamide content are prone to produce smoke, odor, and rough edge waste, which can easily cause physical effects on nearby operators. Summary of the Invention

[0006] In response to the problem that the wrinkle elimination process of fabrics by laser cutting equipment in the existing technology is complicated, time-consuming and labor-intensive, especially the problem that some fabrics made of animal hair or fabrics with high polyester or polyamide content are prone to produce smoke, odor and rough edge waste during cutting, the present invention provides a laser cutting device and cutting method that have better wrinkle elimination effect, reduce labor, improve cutting efficiency, and especially can remove waste and smoke after cutting the fabric surface.

[0007] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0008] A laser cutting device comprises: a frame, a cleaning and leveling mechanism, and a pneumatic conveying mechanism;

[0009] A frame, wherein a first rodless cylinder is mounted on the top of the frame, a second rodless cylinder is mounted on the top of the slider of the first rodless cylinder via a connecting rod, and a laser cutting head is mounted on the bottom of the slider of the second rodless cylinder;

[0010] The top of the frame is provided with a slide slot, and a movable bracket is slidably installed in the slide slot, and a cleaning and leveling mechanism is installed inside the movable bracket, and the cleaning and leveling mechanism includes two support plates, and the two support plates are symmetrically installed inside the movable bracket. A driving motor and two first rod bodies are installed in sequence in a horizontal direction on one side of one of the support plates, and the rotating shaft of the driving motor and one end of the first rod body are fixedly connected to the first cam, and a roller is rotatably installed on the other side of the first cam through a bearing, and the first rod body and the rotating shaft of the driving motor are both sleeved with pulleys, and the outsides of the three pulleys are driven by transmission belts, and one side of the other support plate is rotatably connected to three second tube bodies through bearings, and the outside of each second tube body is sleeved with a second cam, the inside of the second cam is hollow, and the other side of the second cam is connected to the first tube body, the outside of the first tube body is rotatably installed on the other end of the roller through a bearing, and the outside of the roller is provided with a plurality of through holes arranged at equal intervals, and an air pressure conveying mechanism for extracting gas from the roller is installed inside the frame.

[0011] The laser cutting device adopting the above technical solution consists of a frame, a cleaning and leveling mechanism and a pneumatic conveying mechanism. The pulley rotates under the drive of the driving motor, and the mutual transmission between multiple first cams is realized by using the transmission belt. The roller rotates in a circle under the rotation of the first cam, and drives the second cam to rotate at the same time. Every time the roller rotates one circle, the fabric is rolled to fit the fabric, thereby eliminating wrinkles on the surface of the fabric. At the same time, the fabric can also be pressed to prevent the fabric from shaking and deviating during cutting. When eliminating wrinkles on the fabric surface, the air pump is started, and the air pump outlet discharges gas. The gas enters the second cam through the vertical hose and the horizontal hose. Finally, the gas in the second cam will be continuously discharged to the outside through the through hole on the roller, thereby removing the waste and smoke after cutting on the fabric surface.

[0012] Furthermore, the pneumatic conveying mechanism includes a box, a vertical hose and a horizontal hose. The box is installed inside the frame, and an air pump is installed inside the box. One end of the vertical hose passes through the box and is connected to the air outlet of the air pump. The horizontal hose is connected to the other end of the vertical hose. The outside of the horizontal hose is connected to the inside of the second pipe body through a connecting pipe.

[0013] Furthermore, both sides of the frame are fixedly connected with fixed plates, a motor is installed on one side of one of the fixed plates, the rotating shaft of the motor is fixedly connected with a screw rod, the other end of the screw rod is rotatably installed on one side of the other fixed plate through a bearing, and the inner top of the movable bracket is fixedly connected with a fixed block, a threaded groove is provided inside the fixed block, and the fixed block is connected to the outside of the screw rod through the threaded groove.

[0014] Furthermore, a DSP controller is installed inside the box, and a touch panel is installed outside the box.

[0015] Furthermore, the control output end of the DSP controller is respectively connected to the electric control ends of the first rodless cylinder, the second rodless cylinder, the motor and the drive motor, and the signal end of the touch panel is interactively connected to the signal end of the DSP controller.

[0016] Furthermore, both ends of the first rodless cylinder and both ends of the second rodless cylinder are fixedly connected to limit blocks.

[0017] Furthermore, a partition is fixedly connected to the interior of the box, and a filter is embedded on the top of the box.

[0018] Furthermore, a door is hinged on one side of the box body via a hinge.

[0019] Furthermore, reinforcing ribs are fixedly connected to the legs of the frame.

[0020] The present invention also provides a laser cutting method, which uses the above-mentioned laser cutting device to cut cloth, and specifically includes the following steps:

[0021] S1. Place the fabric to be cut on the top table of the frame. The first rodless cylinder controls the slider to drive the second rodless cylinder to move on the frame in the X-axis. At the same time, the second rodless cylinder controls the slider to drive the laser cutting head to move in the Y-axis, thereby achieving laser cutting operations in the horizontal X / Y axis directions.

[0022] S2. Before and after the fabric is cut, the drive motor is started to rotate the rotating shaft and the pulley. The transmission belt is used to realize mutual transmission between the multiple first cams. The roller rotates in a circle under the rotation of the first cam, and drives the second cam to rotate at the same time. Each rotation of the roller presses and rolls the fabric, thereby eliminating wrinkles on the fabric surface.

[0023] S3. When removing wrinkles from the fabric surface, the air pump is started, and the air is discharged from the air pump outlet. The air enters the second cam through the vertical hose and the horizontal hose. Finally, the air in the second cam is continuously discharged to the outside through the through-holes on the roller, thereby removing the waste and smoke after cutting on the fabric surface;

[0024] S4. In steps S1-S3, the DSP controller can control the first rodless cylinder, the second rodless cylinder, the motor and the drive motor through the control signal of the touch panel.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention rotates a pulley driven by a drive motor and utilizes a transmission belt to achieve mutual transmission between multiple first cams. The roller rotates in a circular motion under the rotation of the first cam, driving the second cam to rotate simultaneously. Each rotation of the roller rolls the fabric in a manner that fits the fabric, thereby eliminating wrinkles on the fabric surface. At the same time, the fabric can be pressed to prevent shaking and deviation during cutting.

[0027] 2. When removing wrinkles on the fabric surface, the air pump is started to allow the gas to enter the second cam through the vertical hose and the horizontal hose. Finally, the gas in the second cam is continuously discharged to the outside through the through-holes on the roller, thereby removing the waste and smoke after cutting on the fabric surface. At the same time, when the through-holes on the roller are facing the fabric below, the outward discharged airflow will improve the efficiency of removing wrinkles on the fabric surface.

[0035] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0036] Example 1

[0037] like Figure 1-6 As shown, this embodiment provides a laser cutting device, including a frame 1, a cleaning and leveling mechanism, and a pneumatic conveying mechanism.

[0038] Among them, a first rodless cylinder 2 is installed on the top of the frame 1, a second rodless cylinder 3 is installed on the top of the slider of the first rodless cylinder 2 through a connecting rod, and a laser cutting head 4 is installed on the bottom of the slider of the second rodless cylinder 3;

[0039] Among them, the top of the frame 1 is provided with a slide groove 6, and a movable bracket 13 is slidably installed in the slide groove 6. A cleaning and leveling mechanism is installed inside the movable bracket 13. The cleaning and leveling mechanism includes two support plates 5. The two support plates 5 are symmetrically installed inside the movable bracket 13. A driving motor 11 and two first rods 23 are installed in sequence in the horizontal direction on one side of one support plate 5. The rotating shaft of the driving motor 11 and one end of the first rod 23 are fixedly connected to the first cam 7. The other side of the first cam 7 is rotatably installed with a roller 10 through a bearing. The rotating shaft of the first rod 23 and the driving motor 11 are fixedly connected to the first cam 7. The outside of the moving shaft is sleeved with pulleys 9, and the outside of the three pulleys 9 is driven by a transmission belt 8. One side of the other support plate 5 is rotatably connected to three second tubes 30 through bearings. The outside of each second tube 30 is sleeved with a second cam 31. The inside of the second cam 31 is hollow, and the other side of the second cam 31 is connected to the first tube 29. The outside of the first tube 29 is rotatably installed on the other end of the roller 10 through a bearing. A number of through holes 24 arranged at equal distances are opened on the outside of the roller 10, and a pneumatic conveying mechanism for extracting gas from the roller 10 is installed inside the frame 1.

[0040] Specifically, the air pressure conveying mechanism includes a box body 17, a vertical hose 19 and a horizontal hose 14. The box body 17 is installed inside the frame 1, and an air pump 25 is installed inside the box body 17. One end of the vertical hose 19 passes through the box body 17 and is connected to the air outlet of the air pump 25. The horizontal hose 14 is connected to the other end of the vertical hose 19. The outside of the horizontal hose 14 is connected to the inside of the second tube body 30 through the connecting pipe. Through the above technical solution, when in use, by starting the air pump 25, air pressure is generated in the vertical hose 19 and the horizontal hose 14. The interior of the second cam 31 is set to be hollow, and one side of the second cam 31 is connected to the horizontal hose 14 through the second tube body 30, and the other side is connected to the roller 10 through the first tube body 29. After the air pump 25 is started, the gas enters the second cam 31 through the vertical hose 19 and the horizontal hose 14. Finally, the gas in the second cam 31 will be continuously discharged to the outside through the through hole 24 on the roller 10.

[0041] Specifically, both sides of the frame 1 are fixedly connected to a fixed plate 20, and a motor 18 is installed on one side of a fixed plate 20. The rotating shaft of the motor 18 is fixedly connected to a screw rod 22, and the other end of the screw rod 22 is rotatably installed on one side of the other fixed plate 20 through a bearing. The inner top of the movable bracket 13 is fixedly connected to a fixed block 21, and a threaded groove is provided inside the fixed block 21, and the fixed block 21 is connected to the outside of the screw rod 22 through the threaded groove. Through the above technical solution, the screw rod 22 is driven to rotate by starting the motor 18 on one side of the fixed plate 20, wherein the movable bracket 13 is threadedly connected to the screw rod 22 through the fixed block 21 fixed at the inner top. After the screw rod 22 rotates, it can drive the movable bracket 13 to move horizontally in the slide groove 6, thereby improving the flexibility of the cleaning and leveling mechanism, and eliminating the need for the operator to manually move the movable bracket 13.

[0042] Specifically, a DSP controller 27 is installed inside the box 17, and a touch panel 15 is installed outside the box 17; the control output end of the DSP controller 27 is respectively connected to the electrical control end of the first rodless cylinder 2, the second rodless cylinder 3, the motor 18 and the drive motor 11, and the signal end of the touch panel 15 is interactively connected to the signal end of the DSP controller 27. Through the above technical solution, the DSP controller 27 can control the first rodless cylinder 2, the second rodless cylinder 3, the motor 18 and the drive motor 11 through the control signal of the touch panel 15.

[0043] Specifically, both ends of the first rodless cylinder 2 and the second rodless cylinder 3 are fixedly connected to the limit blocks 12. Through the above technical solution, both ends of the first rodless cylinder 2 and the second rodless cylinder 3 limit the moving distance of the slider through the limit blocks 12.

[0044] Specifically, a partition 28 is fixedly connected to the inside of the box 17, and a filter 26 is embedded in the top of the box 17. Through the above technical solution, the air inlet of the air pump 25 is located inside the box 17. The filter 26 can filter and intercept impurities in the air when the air pump 25 draws air. The partition 28 can block the air entering the filter 26 to prevent external gas from contacting the DSP controller 27 on one side for a long time.

[0045] Specifically, a door 32 is hinged on one side of the box body 17 through a hinge. Through the above technical solution, the door 32 can control the switch on one side of the box body 17, which is convenient for maintaining and repairing the DSP controller 27 and the air pump 25 in the box body 17.

[0046] Specifically, the legs of the frame 1 are fixedly connected with reinforcing ribs 16 .

[0047] Structural principle: When the present invention is used, the cloth to be cut is placed on the top table of the frame 1, and the first rodless cylinder 2 controls the slider to drive the second rodless cylinder 3 to move on the frame 1 along the X axis. At the same time, the second rodless cylinder 3 controls the slider to drive the laser cutting head 4 to move along the Y axis, thereby realizing the laser cutting operation in the horizontal X / Y axis direction. Before and after cutting the cloth, the present invention starts the driving motor 11 to rotate the rotating shaft, and drives the pulley 9 to rotate. The transmission belt 8 is used to realize the mutual transmission between the multiple first cams 7. The roller 10 rotates in a circle under the rotation of the first cam 7, and drives the second cam 31 to rotate at the same time. Every time the roller 10 rotates one circle, the cloth is rolled to fit, thereby eliminating wrinkles on the surface of the cloth. At the same time, the cloth can also be pressed to avoid shaking and deviation of the cloth during cutting.

[0048] When eliminating wrinkles on the fabric surface, air pressure is generated in the vertical hose 19 and the horizontal hose 14 by starting the air pump 25. The interior of the second cam 31 is set to be hollow, and one side of the second cam 31 is connected to the horizontal hose 14 through the second tube body 30, and the other side is connected to the roller 10 through the first tube body 29. After the air pump 25 is started, the gas enters the second cam 31 through the vertical hose 19 and the horizontal hose 14. Finally, the gas in the second cam 31 will be continuously discharged to the outside through the through hole 24 on the roller 10, thereby removing the waste and smoke after cutting the fabric surface. At the same time, when the through hole 24 on the roller 10 is facing the fabric below, the outwardly discharged airflow will improve the efficiency of eliminating wrinkles on the fabric surface. Among them, the DSP controller 27 can control the first rodless cylinder 2, the second rodless cylinder 3, the motor 18 and the drive motor 11 through the control signal of the touch panel 15.

[0049] Example 2

[0050] This embodiment also provides a laser cutting method, which uses the above-mentioned laser cutting device to cut cloth, and specifically includes the following steps:

[0051] S1. Place the fabric to be cut on the top table of the frame 1. Use the first rodless cylinder 2 to control the slider to drive the second rodless cylinder 3 to move on the X-axis on the frame 1. At the same time, use the second rodless cylinder 3 to control the slider to drive the laser cutting head 4 to move on the Y-axis, thereby realizing the laser cutting operation in the horizontal X / Y axis direction.

[0052] S2. Before and after the fabric is cut, the drive motor 11 is started to rotate the rotating shaft and the pulley 9. The transmission belt 8 is used to realize mutual transmission between the multiple first cams 7. The roller 10 rotates in a circular motion under the rotation of the first cam 7 and drives the second cam 31 to rotate at the same time. Each rotation of the roller 10 presses and rolls the fabric, thereby eliminating wrinkles on the fabric surface.

[0053] S3. When removing wrinkles from the fabric surface, the air pump 25 is started, and the air outlet of the air pump 25 discharges gas. The gas enters the second cam 31 through the vertical hose 19 and the horizontal hose 14. Finally, the gas in the second cam 31 is continuously discharged to the outside through the through hole 24 on the roller 10, thereby removing the waste and smoke after cutting on the fabric surface;

[0054] S4. In steps S1-S3, the DSP controller 27 can control the first rodless cylinder 2, the second rodless cylinder 3, the motor 18 and the drive motor 11 through the control signal of the touch panel 15.
