Technical Field
[0001] The present invention relates to the technical field of laser cutting, and particularly relates to a laser cutting device and process for steel-wood furniture. Background Art
[0002] Steel-wood furniture is a type of furniture that combines metal materials and wood. It combines the firmness of metal materials and the natural beauty of wood, and occupies a place in the furniture market. During the production of steel-wood furniture, it is usually necessary to cut the wood and metal materials in advance according to a set shape. The commonly used metal materials are steel and aluminum. When cutting metal materials, a laser cutting device is usually used. The laser cutting device is a highly integrated device of optics, mechanics, and electricity. It uses a high-power density laser beam to scan the surface of the material, heats the material to thousands to tens of thousands of degrees Celsius in an extremely short time, melts or vaporizes the material, and then uses high-pressure gas to blow away the melted or vaporized substance from the cut seam, so as to achieve the purpose of cutting the material.

A plurality of shoveling plates 52 are installed on the movable frame 51. Connecting frames 53 are respectively connected to the bottom parts on both sides of the movable frame 51. The plurality of shoveling plates 52 are divided into multiple groups. One group of shoveling plates 52 is set to two. The two shoveling plates 52 in the same group are respectively in sliding contact with both sides of one of the serrated plates 3. When the multiple groups of shoveling plates 52 move, they respectively shovel off the slag attached to both sides of the serrated plates 3 with which they are in contact. The slag cleaning device 5 also includes two residual tooth rings 54, two gears 57 and four fixing rods 510. The two residual tooth rings 54 and the two gears 57 are respectively rotatably installed on the inner walls of the front and rear sides of the machine base 1.

When the residual tooth ring 54 rotates, it drives the gear 57 to rotate. The four fixing rods 510 are respectively connected to the inner walls of the front and rear sides of the machine base 1. A resilient plate 511 is connected to the fixing rod 510 through a spring. The four fixing rods 510 are respectively located on both sides of the two gears 57.

A plurality of slag cleaning devices 5 are provided, and the plurality of slag cleaning devices 5 are arranged side by side below the plurality of serrated plates 3. The two abutting rods 56 come into contact with the two dial rods 55 of the plurality of slag cleaning devices 5 in sequence during the movement. During the process of the cutting machine 4 moving to the right, it triggers the plurality of slag cleaning devices 5 in sequence, so that the slag cleaning device 5 cleans the serrated plates 3 that have just completed cutting, and shovels off the just-solidified or not fully solidified slag, achieving the effect of cleaning in time following the cutting rhythm of the cutting machine 4;At both ends of the shovel plate 52, a plurality of elastic pieces 512 are respectively connected. On one side of the two mounting frames 2 close to each other, elastic strips 513 are respectively connected.

The shovel plate 52 can further promote the effect of shoveling molten slag through vibration; through the setting of the plurality of slag cleaning devices 5, the plurality of movable frames 51 can move up and down reciprocally in sequence following the cutting rhythm of the cutting machine 4. The molten slag attached to the plurality of serrated plates 3 is shoveled off by the plurality of shovel plates 52 on the movable frames 51, achieving the effect of timely cleaning the molten slag after cutting and avoiding the accumulation of molten slag; through the setting of the elastic pieces 512, the shovel plate 52 can also vibrate during operation. The shovel plate 52 can further enhance the efficiency of shoveling molten slag through vibration and optimize the cleaning effect.
[0023] Further, please refer to Figure 9 - Figure 11 Figure, the collecting device 6 for collecting molten slag. The collecting device 6 includes a hopper 61. The hopper 61 is installed in the machine base 1 through a bracket. The hopper 61 is located below the plurality of movable frames 51. A plurality of leakage grooves are provided on the movable frames 51. An outlet is provided in the middle part of the hopper 61. A collecting box 62 is installed inside the machine base 1. The collecting box 62 is located below the outlet of the hopper 61. A first box 63 and a second box 64 are slidably connected inside the collecting box 62. The first box 63 is located on the left side of the second box 64. The molten slag shoveled off by the shovel plate 52 falls into the hopper 61 through the leakage grooves of the movable frame 51. The molten slag in the hopper 61 falls into the first box 63 and the second box 64 inside the collecting box 62 through the outlet; a plurality of groups of pry bars 66 are rotatably installed at the bottom of the hopper 61. One group of pry bars 66 is set to two. A hammer 67 is connected between the two pry bars 66 of the same group through a sliding hinge. The plurality of groups of pry bars 66 are respectively located below the plurality of movable frames 51. A column 65 is connected to the bottom of the connecting frame 53. The two columns 65 and the two pry bars 66 below the same movable frame 51 are respectively connected through a sliding hinge. When the plurality of hammers 67 move, they all contact the bottom of the hopper 61. When the two columns 65 move up and down, they drive the hammer 67 to move downward and then reset upward by using the lever principle through the two pry bars 66. When the hammer 67 resets upward, it strikes the bottom of the hopper 61 to promote the sliding of the molten slag in the hopper 61. The plurality of hammers 67 respectively follow the triggering of the plurality of slag cleaning devices 5 to strike each position of the bottom of the hopper 61 to promote the sliding of the molten slag to the outlet; through the setting of the collecting device 6, the hopper 61 can collect the shoveled molten slag, and the plurality of hammers 67 can strike the bottom of the hopper 61 following the operation of the slag cleaning device 5 to promote the sliding of the molten slag in the hopper 61.
[0024] Still further, please refer to Figure 12 - Figure 14, the collecting device 6 further includes a sorting section 7. The sorting section 7 includes a fixed guide plate 71, a movable guide plate 72, a magnetic guide plate 73, and a triangular plate 74. The fixed guide plate 71 is installed on the left inner wall of the discharge port of the hopper 61. The movable guide plate 72 is rotatably installed on the right inner wall of the discharge port of the hopper 61. The magnetic guide plate 73 is slidably installed through the right inner wall of the discharge port of the hopper 61. The triangular plate 74 is installed on the inner wall of the collecting box 62. The triangular plate 74 is located between the first box 63 and the second box 64. The magnetic guide plate 73 is located below the fixed guide plate 71 and the movable guide plate 72. The end of the movable guide plate 72 contacts the top surface of the magnetic guide plate 73. The magnetic guide plate 73 is located above the triangular plate 74. A magnetic sheet is provided on the top surface of the magnetic guide plate 73. The slag in the discharge port of the hopper 61 falls onto the magnetic guide plate 73 under the guidance of the fixed guide plate 71 and the movable guide plate 72. The magnetic sheet on the magnetic guide plate 73 can adsorb the steel slag. Since the aluminum slag cannot be adsorbed by the magnetic sheet, it slides leftward along the magnetic guide plate 73. Subsequently, the aluminum slag slides into the first box 63 along the left inclined surface of the triangular plate 74. Right-angle rods 75 are respectively connected to two columns 65 on the right side of the magnetic guide plate 73. Two sliding rods 77 are slidably installed on the right outer wall of the discharge port of the hopper 61. Connecting rods 76 are respectively hinged between the two right-angle rods 75 and the two sliding rods 77. A convex block 79 is connected to the right side of the magnetic guide plate 73. Two push rods 78 are hinged to the convex block 79. The ends of the two push rods 78 away from the convex block 79 are respectively hinged to the two sliding rods 77. When the two right-angle rods 75 move upward, they respectively push the two sliding rods 77 towards each other through the two connecting rods 76. When the two sliding rods 77 approach each other, they push the convex block 79 to the right through the two push rods 78. When the convex block 79 moves to the right, it drives the magnetic guide plate 73 to move to the right. The movable guide plate 72 always keeps its end resting on the magnetic guide plate 73 by its own gravity. When the magnetic guide plate 73 moves to the right, the movable guide plate 72 intercepts the slag adsorbed on the surface of the magnetic guide plate 73, causing the slag to slide along the movement of the magnetic guide plate 73 onto the right inclined surface of the triangular plate 74 and then into the second box 64, achieving the effect of classifying and collecting aluminum slag and steel slag; through the setting of the sorting section 7, the magnetic guide plate 73 can adsorb the steel slag, causing the aluminum slag to slide into the first box 63, and the magnetic guide plate 73 can move to the right regularly. By cooperating with the movable guide plate 72, the steel slag adsorbed on the surface of the magnetic guide plate 73 is scraped into the second box 64, achieving the effect of classified collection and facilitating subsequent classified utilization.
[0025] Furthermore, please refer to Figure 12 、 Figure 15, the collecting device 6 further includes an anti-piling part 8. The anti-piling part 8 includes two groups of sliding frames 82. Both groups of sliding frames 82 are slidably mounted on the inner wall of the collecting box 62 through round rods. One group of sliding frames 82 is provided with two. The two groups of sliding frames 82 are respectively located above the first box 63 and the second box 64. A plurality of elastic rods 83 are connected to the bottom of the sliding frame 82. Curved rods 81 are respectively connected to two groups of pry bars 66 on both sides of the discharge port of the hopper 61. The four sliding frames 82 are respectively connected to one end of the four curved rods 81 far from the pry bars 66 through sliding hinges. When the pry bar 66 with the curved rod 81 swings up and down, the sliding frame 82 is driven to slide back and forth through the curved rod 81. The sliding frame 82 drives the plurality of elastic rods 83 at its bottom to move synchronously. The plurality of elastic rods 83 move periodically, which can stir the slag in the first box 63 and the second box 64, break up the slag pile, reduce the height of the slag pile, and help improve the evenness of the slag stacking in the first box 63 and the second box 64; through the setting of the anti-piling part 8, the plurality of elastic rods 83 can move periodically, so as to stir the slag in the first box 63 and the second box 64, break up the higher slag pile, make the slag stacking more uniform, and avoid the higher slag accumulation from affecting the smoothness of the subsequent slag falling. Embodiment
[0026] A laser cutting process for steel-wood furniture, using a laser cutting device for steel-wood furniture in Embodiment 1, further includes the following steps: Step 1: Cutting preparation, prepare the materials in advance and set the cutting route; Step 2: Loading, position and place the materials on the plurality of serrated plates 3, and temporarily fix the periphery of the materials; Step 3: Cutting, start the cutting machine 4, and the cutting machine 4 cuts according to the set cutting route; Step 4: Discharging, take out the cut materials and separate the cut materials from the waste; Step 5: Grinding, grind the periphery of the cut materials to make the cutting surface of the materials smooth and flat; Step 6: Shutdown maintenance, after the cutting operation is completed, turn off the cutting machine 4, and regularly take out the slag waste in the first box 63 and the second box 64.
[0027] With the above structure, the working principle of this case is as follows: The cutting machine 4 is a prior art. The cutting machine 4 can move left and right on the machine base 1 according to the set cutting route. The laser cutting head of the cutting machine 4 can move up and down and back and forth on the cutting machine 4. After the cutting machine 4 is started, it moves from left to right to gradually complete the cutting. The mounting frame 2 and multiple sawtooth plates 3 form a placement table. The material to be cut is placed on the multiple sawtooth plates 3. After the cutting machine 4 starts to move left, the two contact rods 56 at the bottom of the cutting machine 4 contact the two lever rods 55 of the leftmost slag cleaning device 5. The contact rod 56 pushes the lever rod 55 to the right, causing the lever rod 55 to drive the residual gear ring 54 to rotate. The residual gear ring 54 drives the gear 57 to rotate through the teeth. During the rotation of the residual gear ring 54, the gear 57 is driven to rotate one week. The gear 57 drives the roller 59 to rotate one week through the crank arm 58. When the roller 59 rotates one week, the connecting frame 53 is driven to perform a reciprocating up and down movement once through the sliding groove on the connecting frame 53, so that the two connecting frames 53 drive the movable frame 51 to perform a reciprocating up and down movement once. The movable frame 51 drives multiple groups of scraping plates 52 to perform a reciprocating up and down movement once. When the multiple groups of scraping plates 52 move, they respectively scrape off the slag attached to both sides of the sawtooth plates 3 in contact with them. When the residual gear ring 54 is about to rotate to the right in place, the inner wall on the right side of the residual gear ring 54 contacts and presses the rebound plate 511 on the right. When the contact rod 56 is separated from the lever rod 55, the rebound plate 511 drives the residual gear ring 54 and the lever rod 55 to reset to the left by a certain distance through the elastic force of the spring between it and the fixed rod 510. When the cutting machine 4 resets to the left after cutting is completed, the contact rod 56 contacts the lever rod 55 again and drives the lever rod 55 to move to the left, causing the residual gear ring 54 to rotate and reset to the left. Similarly, when the residual gear ring 54 rotates to the left in place, its left inner wall abuts against the rebound plate 511 on the left. After the contact rod 56 is separated from the lever rod 55, the residual gear ring 54 swings to the right by a certain angle, causing the lever rod 55 to be located on the movement track of the contact rod 56 again. The multiple sawtooth plates 3 are divided into multiple segments, and multiple slag cleaning devices 5 are respectively responsible for cleaning multiple segments of the sawtooth plates 3. During the process of the cutting machine 4 moving to the right, multiple slag cleaning devices 5 are triggered in sequence, so that the slag cleaning devices 5 clean the sawtooth plates 3 that have just been cut, and scrape off the just-solidified or not fully solidified slag, achieving the effect of cleaning in time following the cutting rhythm of the cutting machine 4; when the scraping plates 52 move, multiple elastic pieces 512 on both sides of the scraping plates 52 respectively contact the two elastic strips 513. After the elastic pieces 512 contact the elastic strips 513, they vibrate, enabling the multiple elastic pieces 512 to drive the scraping plates 52 to vibrate. The scraping plates 52 can further promote the effect of scraping off the slag through vibration; through the setting of multiple slag cleaning devices 5, multiple movable frames 51 can perform reciprocating up and down movements in sequence following the cutting rhythm of the cutting machine 4. Multiple groups of scraping plates 52 on the movable frames 51 scrape off the slag attached to the multiple sawtooth plates 3, achieving the effect of cleaning the slag in time after cutting is completed and avoiding slag accumulation;Through the arrangement of the elastic piece 512, the shovel plate 52 can vibrate during operation. The vibration of the shovel plate 52 can further enhance the efficiency of shoveling molten slag and optimize the cleaning effect.
[0028] The molten slag shoveled by the shovel plate 52 falls into the hopper 61 through the leakage trough of the movable frame 51. The molten slag in the hopper 61 falls into the first box 63 and the second box 64 in the collection box 62 through the discharge port. When one movable frame 51 and two connecting frames 53 move up and down reciprocally, the two connecting frames 53 drive the two columns 65 to move up and down. When the two columns 65 move up and down, the hammer 67 is driven to move downward and then reset upward by using the lever principle through the two pry bars 66. When the hammer 67 resets upward, it strikes the bottom of the hopper 61 to promote the sliding of the molten slag in the hopper 61. Multiple hammers 67 are respectively triggered following multiple slag cleaning devices 5 to strike various positions at the bottom of the hopper 61 to promote the sliding of the molten slag to the discharge port. Through the arrangement of the collection device 6, the hopper 61 can collect the shoveled molten slag, and multiple hammers 67 can strike the bottom of the hopper 61 following the operation of the slag cleaning device 5 to promote the sliding of the molten slag in the hopper 61.
[0029] The slag in the discharge port of the hopper 61 falls onto the magnetic guide plate 73 under the guidance of the fixed guide plate 71 and the movable guide plate 72. The magnetic chips on the magnetic guide plate 73 can adsorb the steel slag, and the aluminum slag slides leftward along the magnetic guide plate 73 because it cannot be adsorbed by the magnetic chips. Subsequently, the aluminum slag slides into the first box 63 along the left inclined surface of the triangular plate 74. When the two columns 65 on the right side of the magnetic guide plate 73 move up and down reciprocally, the two columns 65 drive the two right-angle rods 75 to move up and down reciprocally once respectively. When the two right-angle rods 75 move upward, they push the two sliding rods 77 towards each other through the two connecting rods 76 respectively. When the two sliding rods 77 approach each other, they push the convex block 79 to the right through the two push rods 78. When the convex block 79 moves to the right, it drives the magnetic guide plate 73 to move to the right. When the two right-angle rods 75 move downward, they drive the two sliding rods 77 to reset through the two connecting rods 76. The two sliding rods 77 drive the convex block 79 to reset to the left through the two push rods 78, and the convex block 79 drives the magnetic guide plate 73 to reset to the left. When the magnetic guide plate 73 moves to the right, since the movable guide plate 72 always keeps its end resting on the magnetic guide plate 73 due to its own gravity, when the magnetic guide plate 73 moves to the right, the movable guide plate 72 intercepts the slag adsorbed on the surface of the magnetic guide plate 73, causing the slag to slide onto the right inclined surface of the triangular plate 74 along the movement of the magnetic guide plate 73 and then into the second box 64, achieving the effect of classifying and collecting the aluminum slag and the steel slag; when the crowbar 66 with the curved rod 81 swings up and down, it drives the sliding frame 82 to slide back and forth through the curved rod 81. The sliding frame 82 drives the multiple elastic rods 83 at its bottom to move synchronously. Since the falling points of the slag falling into the first box 63 and the second box 64 are roughly the same, it is easy for the slag in the first box 63 and the second box 64 to form a pile. A higher pile may affect the smoothness of the subsequent slag falling. The four sliding frames 82 and the multiple elastic rods 83 move periodically, which can stir the slag in the first box 63 and the second box 64, break up the slag pile, reduce the height of the slag pile, and help improve the evenness of the slag stacking in the first box 63 and the second box 64; through the setting of the classification part 7, the magnetic guide plate 73 can adsorb the steel slag, causing the aluminum slag to slide into the first box 63, and the magnetic guide plate 73 can move to the right regularly. By cooperating with the movable guide plate 72, the steel slag adsorbed on the surface of the magnetic guide plate 73 is scraped into the second box 64, achieving the effect of classified collection and facilitating subsequent classified utilization; through the setting of the anti-piling part 8, the multiple elastic rods 83 can move periodically, thereby stirring the slag in the first box 63 and the second box 64, breaking up the higher slag pile, making the slag stacking more even, and avoiding the higher slag pile from affecting the smoothness of the subsequent slag falling.
