Description

Technical Field

[0001] The invention relates to the field of sponge laser cutting machines, in particular to an environmentally friendly sponge laser cutting machine and a cutting method thereof. Background Art

[0002] Laser cutting machine is a machine that processes raw materials with the help of laser cutting technology. It uses the heat of high-temperature laser arc to partially or locally melt (or evaporate) the raw materials, and uses the momentum of high-speed laser to remove the melted raw materials to form a processing method.

[0003] Existing laser cutting machines for cutting sponges generally have a two-dimensional electric track that moves horizontally inside the main machine, and a laser cutting head facing a support frame is arranged on the two-dimensional electric track. The support frame is composed of metal bars arranged at intervals and is used to support the sponge. Some environmentally friendly sponge laser cutting machines will also have a negative pressure smoke extraction duct on one side of the laser cutting head to absorb the exhaust gas generated by laser cutting.

[0004] With regard to the above-mentioned related technologies, when the laser cutting head moves toward the direction where the negative pressure smoke exhaust duct is set, since the exhaust gas generated by the laser cutting has a certain lag in floating upward, when the exhaust gas floats upward and has not yet been collected by the smoke exhaust duct, the smoke exhaust duct has already moved away from the exhaust gas generation position, and the exhaust gas on the moving path of the laser cutting head cannot be well collected. In addition, most of the existing support frames are fixed, and the laser is easily irradiated on the support frame after cutting through the sponge, which may further generate more exhaust gas. In summary, the existing laser cutting machine is not easy to handle the exhaust gas generated in the process of cutting the sponge. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an environmentally friendly sponge laser cutting machine and a cutting method thereof, so as to solve the technical problem that the existing laser cutting machine is not easy to handle the waste gas generated during the sponge cutting process.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an environmentally friendly sponge laser cutting machine, comprising a main unit, wherein slide rails are arranged on both sides of the main unit, and sliding beams are slidably connected to the slide rails, and the two slide rails in the main unit are spaced apart and connected with a bearing beam for bearing the sponge, and a laser cutting head is slidably connected to the sliding beam, and a smoke hood is fixedly connected to the outer wall of the laser cutting head, and the bottom end of the smoke hood is lower than the bottom end of the laser cutting head, and the side wall of the smoke hood is connected to a negative pressure pipe, and an axial flux motor is installed in the smoke hood, and the center of the axial flux motor is connected to a rotating tube, and the bottom end of the laser cutting head is located in the rotating tube, and the bottom end of the rotating tube is rotatably connected to a fan blade.

[0007] By adopting the above technical solution, the negative pressure suction structure in the smoke hood is used to collect the waste gas generated during the laser cutting process. No matter which direction the laser cutting head moves on the plane, the waste gas generated by the cutting will float upward and be within the smoke collection range of the smoke hood, which effectively improves the collection effect of the laser cutting waste gas.

[0008] The present invention is further configured such that at least one smoke collecting pipe is installed in the smoke collecting hood, one end of the smoke collecting pipe is connected to the inner wall of the smoke collecting hood, and the other end is connected to the negative pressure pipe, and a smoke collecting groove is opened at the bottom end of the smoke collecting pipe along the length direction.

[0009] By adopting the above technical solution, smoke overflow caused by the movement of the laser cutting head can be avoided.

[0010] The present invention is further configured such that there are two smoke collecting pipes in the smoke collecting hood, the two smoke collecting pipes are located above the fan blades and are not in contact with the rotating tube, and one end of the two smoke collecting pipes passes through the smoke collecting hood and is connected to the negative pressure pipe.

[0011] By adopting the above technical solution, the two smoke collecting pipes are symmetrically arranged in the smoke collecting hood, which has a good collection effect on the rising smoke.

[0012] The present invention is further configured such that the end of the negative pressure pipe that is not connected to the smoke collection pipe is connected to the exhaust gas treatment equipment through a corrugated air guide pipe.

[0013] By adopting the above technical solution, a better smoke collection effect is achieved.

[0014] The present invention is further configured such that the two slide rails in the main machine are connected to a load-bearing beam by rotating in opposite directions along the length, the load-bearing beam comprises two support plates arranged in an annular direction and at intervals along the axis, both ends of the load-bearing beam are connected to a turntable after passing through the slide rails, an adjustment disk is fixedly connected to the turntable, an opening is provided on the adjustment disk, and the angle of the opening is the same as the angle of interval between the two support plates on the load-bearing beam, a lever is fixedly connected to the sliding beam toward the turntable, and the lever is used to drive the adjustment disk to rotate.

[0015] By adopting the above technical solution, the situation in which the laser cutting head cuts the load-bearing beam can be effectively avoided.

[0016] The present invention is further configured such that a fixed magnet is fixedly connected to the side wall of the slide rail toward the turntable, and a first rotating magnet and a second rotating magnet are annularly connected to the turntable toward the slide rail in an interval manner, and the interval angle between the first rotating magnet and the second rotating magnet is the same as the opening angle on the adjustment disk.

[0017] By adopting the above technical solution, after the adjusting disk is rotated by the shifting rod, the first rotating magnet and the second rotating magnet are alternately matched with the fixed magnet.

[0018] The present invention is further configured such that, when the lever is not in contact with the adjustment disk, at least one side wall of the opening of the adjustment disk faces directly downward, and at least one supporting piece of the bearing beam corresponding to the adjustment disk faces directly upward.

[0019] By adopting the above technical solution, the lever can contact the inclined surface of the adjusting disk when sliding, thereby achieving stable pushing of the adjusting disk to make it rotate.

[0020] The present invention is further configured such that the support plates of the load-bearing beam are provided with blanking openings at intervals along the length direction.

[0021] By adopting the technical solution, waste materials can be easily dropped during the sponge cutting process.

[0022] An environmentally friendly sponge laser cutting method comprises the following steps:

[0023] Step 1: Place the sponge to be cut on the load-bearing beam, and the sliding beam slides from the innermost side of the main machine to the opening direction of the main machine. At the same time, the laser cutting head slides on the sliding beam according to the preset route to laser cut the sponge;

[0024] Step 2: The sliding beam slides in the opposite direction to reset. During this process, the laser cutting head does not need to slide.

[0025] The present invention is further configured such that when the sliding beam slides on the innermost side and the outermost side of the machine body respectively, the directions of the adjustment disk are opposite to each other.

[0026] By adopting the above technical solution, when the lever slides past the adjusting disk, the adjusting disk can be smoothly rotated so that its direction is the same as the direction of the adjusting disk behind the moving direction.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention arranges a disc-shaped smoke collecting hood close to the sponge surface at the laser cutting head, and utilizes the negative pressure suction structure in the smoke collecting hood to collect the waste gas generated during the laser cutting process. No matter which direction the laser cutting head moves on the plane, the waste gas generated by the cutting floats upward and is within the smoke collecting range of the smoke collecting hood, which effectively improves the collection effect of the waste gas from laser cutting;

[0029] 2. The present invention makes the load-bearing beam rotatably connected to the slide rails on both sides, and fixes a rotating disk and an adjusting disk at both ends of the load-bearing beam. The adjusting disk is toggled while the sliding beam slides by using a lever fixedly connected to the sliding beam. When the laser cutting head passes through the load-bearing beam, the load-bearing beam sent by the laser cutting head is separated from the contact with the sponge, which effectively avoids the laser generated by the laser cutting head from cutting the load-bearing beam, thereby effectively reducing the generation of waste gas.

[0030] 3. The present invention uses a lever on the sliding beam to move the adjustment disk, so that the turntable is rotated by the lever during the sliding of the sliding beam, thereby adjusting the angle of the load-bearing beam during the sliding of the sliding beam, so that the two sides of the load-bearing beam alternately contact the bottom surface of the sponge, and under the premise of stably supporting the sponge body, the laser cutting head is effectively prevented from cutting the load-bearing beam;

[0031] 4. The present invention arranges blanking openings at intervals along the length direction of the bearing beam, so that the waste generated by laser cutting of the sponge can fall through the blanking openings or the gaps between the bearing beams, and in the process of the sliding beam sliding to the inner side of the main machine and then sliding out from the inner side of the main machine, the bearing beam is sequentially changed in angle to support different positions on the back of the sponge, so that the waste cut from the sponge can fall better;

[0032] 5. The present invention arranges an axial flux motor in the smoke collecting hood, uses the axial flux motor to drive the rotating tube to rotate, and fixes the fan blade structure at the bottom end of the rotating tube. While the light beam of the laser cutting head can normally cut the sponge, the fan blade structure is as close to the sponge as possible, and the light beam irradiation point of the laser cutting head is taken as the center, so as to effectively avoid the overflow of smoke and further improve the collection effect of exhaust gas.

[0033] 6. The present invention sets a smoke collecting pipe for connecting the negative pressure pipe in the smoke collecting hood, and sets a smoke collecting groove at the bottom end of the smoke collecting pipe along the length direction, so that the exhaust gas generated by laser cutting can be absorbed more evenly in the smoke collecting hood, thereby preventing the smoke from overflowing due to the sudden change of the path of the laser cutting head during movement.

DETAILED DESCRIPTION

[0044] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] The following describes an embodiment of the present invention based on its overall structure. Embodiment 1

[0046] An environmentally friendly sponge laser cutting machine, such as Figure 1-9 As shown, it includes a main unit 1, both sides of the main unit 1 are provided with slide rails 2, the slide rails 2 are slidably connected with slide beams 3, the slide beams 3 are slidably connected with a laser cutting head 4, the two slide rails 2 in the main unit 1 are spaced apart and connected with a load-bearing beam 12 for carrying a sponge, the slide beams 3 are slidably connected with a laser cutting head 4, the outer wall of the laser cutting head 4 is fixedly connected with a smoke hood 5, the bottom end of the smoke hood 5 is lower than the bottom end of the laser cutting head 4, the bottom end of the smoke hood 5 does not contact the sponge, the side wall of the smoke hood 5 is connected with a negative pressure pipe 6, an axial flux motor 9 is installed in the smoke hood 5, the center of the axial flux motor 9 is connected with a rotating tube 10, the bottom end of the laser cutting head 4 is located in the rotating tube 10, the bottom end of the rotating tube 10 is rotatably connected with a fan blade 11, specifically, the blowing direction of the fan blade 11 when the fan blade 11 rotates is toward the inside of the smoke hood 5.

[0047] See also Figure 1-2 , Figure 8-9The end of the negative pressure pipe 6 that is not connected to the smoke collection pipe 7 is connected to the exhaust gas treatment equipment through a corrugated air duct. Specifically, the exhaust gas treatment equipment of the laser cutting machine is a conventional setting on the existing laser cutting machine. This application does not make improvements to the existing exhaust gas treatment equipment of the laser cutting machine, so it is not elaborated. During the movement of the laser cutting head 4 in the main machine 1, the negative pressure pipe 6 is always maintained in a negative pressure state, and then when the fan blades 11 rotate, the smoke is better collected.

[0048] See also Figure 1-9 At least one smoke collecting pipe 7 is installed in the smoke collecting hood 5, one end of the smoke collecting pipe 7 is connected to the inner wall of the smoke collecting hood 5, and the other end is connected to the negative pressure pipe 6. A smoke collecting groove 8 is opened at the bottom of the smoke collecting pipe 7 along the length direction. The smoke collecting groove 8 arranged at the bottom of the smoke collecting pipe 7 is used to collect the rising smoke, which can effectively improve the uniformity of smoke attraction and avoid smoke overflow caused by the movement of the laser cutting head 4. There are two smoke collecting pipes 7 in the smoke collecting hood 5. The two smoke collecting pipes 7 are located above the fan blades 11 and do not contact the rotating tube 10. One end of the two smoke collecting pipes 7 passes through the smoke collecting hood 5 and is connected to the negative pressure pipe 6. The two smoke collecting pipes 7 are symmetrically arranged in the smoke collecting hood 5, which has a good collection effect on the rising smoke. The supporting plates of the load-bearing beam 12 are spaced apart with blanking openings 19 along the length direction to facilitate the falling of waste materials during the sponge cutting process. Embodiment 2

[0049] An environmentally friendly sponge laser cutting machine, such as Figure 1-9 As shown, on the basis of embodiment 1, the difference from embodiment 1 is that the two slide rails 2 in the main machine 1 are connected to the load-bearing beam 12 by rotating in opposite intervals along the length, the load-bearing beam 12 includes two support plates arranged in an annular direction and at intervals along the axial direction, and both ends of the load-bearing beam 12 are connected to the turntable 13 after passing through the slide rails 2, and the turntable 13 is fixedly connected to an adjusting disk 14, and an opening is provided on the adjusting disk 14, and the angle of the opening is the same as the angle of interval between the two support plates on the load-bearing beam 12, and a lever 15 is fixedly connected to the sliding beam 3 toward the turntable 13, and the lever 15 is used to drive the adjusting disk 14 to rotate, and when the sliding beam 3 slides to the top of the load-bearing beam 12, the lever 15 connected to the sliding beam 3 can drive the adjusting disk 14 on both sides of the load-bearing beam 12, so that the load-bearing beam 12 rotates, and the support plates of the load-bearing beam 12 are separated from the contact with the bottom surface of the sponge, effectively avoiding the situation where the laser cutting head 4 cuts the load-bearing beam 12.

[0050] See also Figure 3-7The side wall of the slide rail 2 is fixedly connected with a fixed magnet 16 in the direction of the turntable 13, and the turntable 13 is annularly connected with a first rotating magnet 17 and a second rotating magnet 18 in the direction of the slide rail 2. Specifically, the fixed magnet 16, the first rotating magnet 17 and the second rotating magnet 18 are all strip-shaped, and the fixed magnet 16 is vertically fixed to the surface of the slide rail 2 facing the turntable 13. When the lever 15 turns the adjusting disk 14 to make it rotate, as the lever 15 continues to move, the adjusting disk 14 rotates to a state where the other side of the opening is parallel to the ground. At this time, the state of the first rotating magnet 17 or the second rotating magnet 18 magnetically attracting the fixed magnet 16 can be switched. Specifically, the top surface of the lever 15 contacts the plane parallel to the ground at the opening of the adjusting disk 14, and the interval angle between the first rotating magnet 17 and the second rotating magnet 18 is the same as the opening angle on the adjusting disk 14. After the adjusting disk 14 is rotated by the lever 15, the first rotating magnet 17 and the second rotating magnet 18 are alternately matched with the fixed magnet 16.

[0051] See also Figure 3-7 When the lever 15 is not in contact with the adjusting disk 14, at least one side wall of the opening of the adjusting disk 14 faces downward, and at least one supporting piece of the supporting beam 12 corresponding to the adjusting disk 14 faces upward. When one of the side walls at the opening of the adjusting disk 14 faces downward, the other side wall is in an inclined state, so that the lever 15 can contact the inclined surface of the adjusting disk 14 when sliding, thereby achieving stable pushing of the adjusting disk 14 to make it rotate. Specifically, the lever 15 can only drive one supporting beam 12 to rotate at the same time. The rotation of the supporting beam 12 under the driving of the lever 15 will not affect the stability of the sponge. At this time, the sponge is well supported by the remaining supporting beams 12.

[0052] An environmentally friendly sponge laser cutting method comprises the following steps:

[0053] Step 1: Place the sponge to be cut on the load-bearing beam, and the sliding beam slides from the innermost side of the main machine to the opening direction of the main machine. At the same time, the laser cutting head slides on the sliding beam according to the preset route to laser cut the sponge;

[0054] Step 2: The sliding beam slides in the opposite direction to reset. During this process, the laser cutting head does not need to slide. When the sliding beam slides to the innermost and outermost sides of the machine body respectively, the directions of the adjustment disk are opposite. When the lever slides through the adjustment disk, the adjustment disk can be smoothly rotated so that its direction is the same as the direction of the adjustment disk behind the moving direction.

[0055] The working principle of the present invention is as follows: after the sponge is placed inside the main machine 1, the sliding beam 3 starts to move from the innermost side of the main machine 1 toward the opening of the main machine 1, and at the same time, the laser cutting head 4 moves transversely on the sliding beam 3 according to a set path to perform laser cutting on the sponge. While the sliding beam 3 slides toward the opening direction of the main machine 1, the lever 15 connected thereto sequentially shifts the adjusting disk 14. In the process of the lever 15 shifting the adjusting disk 14 to rotate it, the bearing beam 12 corresponding to the adjusting disk 14 is separated from the contact with the bottom surface of the sponge until the bearing beam 12 is replaced by another beam. The support plate is in contact with the bottom surface of the sponge. Similarly, during the reverse sliding process of the sliding beam 3, the smoke generated by the laser cutting floats upward in the smoke collecting hood 5. Affected by the negative pressure generated by the rotation of the fan blades 11 and the negative pressure of the negative pressure pipe 6, the smoke flows smoothly into the smoke collecting pipe 7 through the smoke collecting groove 8 at the bottom of the smoke collecting pipe 7, and flows into the negative pressure pipe 6 along the smoke collecting pipe 7 until it enters the exhaust gas treatment box. No matter which direction the laser cutting head 4 moves on the plane, the smoke generated by cutting the sponge can be fully collected by the smoke collecting hood 5, effectively avoiding the occurrence of smoke leakage.

[0056] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention.
