DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0041] like Figures 1 to 4 As shown, an automobile decorative panel profiling cutting device and a control method thereof according to an embodiment of the present invention include a base 1, a top of the base 1 is provided with a plurality of steel tooth plates 13, a bracket assembly 11 is provided above the base 1, and a laser cutting head 12 is mounted on the bracket assembly 11;

[0042] A positioning plate 2 is provided on one side of the base 1, and a first connecting member 21 is provided on the side of the positioning plate 2. A material receiving box 22 is provided at the end of the first connecting member 21. The material receiving box 22 is inserted between adjacent steel tooth plates 13, and the spacing between adjacent steel tooth plates 13 is the same as the width of the material receiving box 22; when the material receiving box 22 is inserted between adjacent steel tooth plates 13, both ends are located on the outside of the base 1; the top of the material receiving box 22 is at the same height as the top of the steel tooth plate 13;

[0043] The embodiment of the present invention provides a receiving box 22. Since the distance between adjacent steel tooth plates 13 is the same as the width of the receiving box 22, the receiving box 22 is inserted between the steel tooth plates 13 and contacts the side surfaces of the steel tooth plates 13 on both sides. During the cutting operation, the metal plate is placed on the top of the steel tooth plate 13. As the laser cutting head 12 cuts the metal plate, the generated metal debris falls to the bottom of the metal plate and is then received by the receiving box 22. The receiving box 22 receives the high-temperature metal debris, effectively preventing the high-temperature metal debris from adhering to the surface of the steel tooth plate 13. After a period of use, the receiving box 22 can be disassembled and replaced. The receiving box 22 is made of plastic, has a low cost, and can be used in large quantities. Therefore, a receiving box 22 can be set between adjacent steel tooth plates 13, which can effectively improve the service life of the steel tooth plates 13.

[0044] A high-temperature resistant metal sheet is attached to the top of the material receiving box 22; when the metal plate is placed on the top of the steel tooth plate 13, since the top of the material receiving box 22 is at the same height as the top of the steel tooth plate 13, the top of the material receiving box 22 can contact the bottom surface of the metal plate. When cutting the metal plate, the metal plate generates high temperature, and the top of the material receiving box 22 is attached with a high-temperature resistant metal sheet, thereby improving the high-temperature resistance of the material receiving box 22 and ensuring the use effect.

[0045] like Figures 1 to 4 As shown, the first connecting member 21 is specifically a hydraulic cylinder; the hydraulic cylinder housing is partially installed on the side of the positioning plate 2, and the output end of the hydraulic cylinder is connected to the material receiving box 22; when in use, the hydraulic cylinder can drive the material receiving box 22 to move back and forth between adjacent steel tooth plates 13, that is, the material receiving box 22 continues to move relative to the steel tooth plates 13, preventing high-temperature debris from falling between the steel tooth plates 13 and the material receiving box 22 and sticking the two together, which is convenient for the subsequent removal of the material receiving box 22.

[0046] like Figures 3 to 10 As shown, the interior of the material receiving box 22 is provided with an exhaust head 3, which is installed at the end position of the material receiving box 22. The side of the exhaust head 3 is connected to a first air pipe 31, and the first air pipe 31 is externally connected to a first air pump;

[0047] The inner wall of the receiving box 22 is provided with a plurality of grooves, in which an intercepting rod 32 is rotatably arranged. The intercepting rod 32 is used to receive the debris generated by the laser cutting. The bottom end of the intercepting rod 32 is fixedly connected to a dropper plate 321, and an oscillating plate 322 is provided on the side of the dropper plate 321. The end of the intercepting rod 32 is sleeved with a gear ring 34, and the gear ring 34 is meshed with a rack 35, which is fixed to the inner wall of the receiving box 22.

[0048] When in use, the first air pump connected to the first air pipe 31 is started, and the first air pump exhausts the air to the exhaust head 3 through the first air pipe 31, and the exhaust head 3 exhausts the air to the receiving box 22, so that the fallen debris is concentrated into the receiving box 22, and when it comes into contact with the intercepting rod 32 in the receiving box 22, it adheres to the surface of the intercepting rod 32, so that the high-temperature debris is collected in a concentrated manner, thereby improving the collection effect; and the setting of the intercepting rod 32 can make the high-temperature debris at different positions quickly be taken up when falling into the receiving box 22, avoiding the high-temperature debris from being concentrated in one place under the action of the air flow, which affects the debris collection process; When the outer exhaust head 3 is used to extract air from the docking box 22, the dropper plate 321 is driven by the air flow to drive the intercepting rod 32 to rotate. When the dropper plate 321 rotates, the oscillation plate 322 is driven to rotate synchronously. When the oscillation plate 322 rotates, the bottom end will hit the surface of the intercepting rod 32 below, causing the intercepting rod 32 to oscillate, thereby driving the high-temperature debris adhering to the intercepting rod 32 to fall off. In addition, when the intercepting rod 32 rotates, the tooth ring 34 at the end of the intercepting rod 32 engages with the tooth plate 35 for transmission, causing the intercepting rod 32 to move upward. As the intercepting rod 32 is reset and rotated, the end of the intercepting rod 32 moves up and down. The cam 322 is moved upwards and downwards to move the cam 322 in a synchronous manner. Initially, the bottom end of the cam 322 contacts the cam 322 below, so the cam 322 will intermittently hit the cam 322 below, thereby further improving the oscillation effect of the cam 322. At the same time, the vibration of the cam 322 will cause the material receiving box 22 to oscillate synchronously, so the high-temperature debris adhering to the inner wall of the material receiving box 22 will vibrate synchronously and be driven to fall downwards, thereby preventing the high-temperature debris from accumulating on the inner wall of the material receiving box 22 and affecting the continuous use of the material receiving box 22. 22 use; it should be pointed out that, in this process, it is necessary to control the output power of the first air pump connected to the first air pipe 31, so that the air flow intensity in the receiving box 22 increases and decreases intermittently, and when the air flow intensity in the receiving box 22 decreases, the drop plate 321 resets and rotates under the action of its own gravity, so that the oscillation plate 322 breaks away from the contact with the interception rod 32, and then when the air flow intensity increases, the drop plate 321 repeatedly drives the interception rod 32 to twist, so that the oscillation plate 322 reciprocates and hits the interception rod 32 below, so that the interception rod 32 and the receiving box 22 continue to oscillate, ensuring the use effect.

[0049] A filter screen 33 is provided inside the receiving box 22 , and the filter screen 33 is provided at the exhaust port of the exhaust head 3 ; by providing the filter screen 33 , the exhaust head 3 can be prevented from sucking high-temperature debris into the interior, causing blockage of the exhaust head 3 .

[0050] The inner bottom wall of the receiving box 22 is provided with a cavity plate 4, the interior of the cavity plate 4 is provided with a cavity, and the top of the cavity plate 4 is provided with a second air pipe 41, the second air pipe 41 is connected to the cavity, and the second air pipe 41 is externally connected to a second air pump;

[0051] The top of the cavity plate 4 is evenly provided with a plurality of air holes; the filter screen 33 is located between the air extraction head 3 and the cavity plate 4;

[0052] During use, the second air pump connected to the second air pipe 41 is started, and the second air pump fills the external water vapor into the cavity inside the cavity plate 4 through the second air pipe 41; then the water vapor is ejected upward through the air holes at the top of the cavity plate 4, so that the high-temperature debris entering the receiving box 22 is quickly cooled and hardened, preventing the high-temperature debris from contacting and adhering to the surface of the filter 33 and clogging the filter 33; at the same time, the water vapor will also wet the intercepting rod 32, and the vibration of the intercepting rod 32 will effectively prevent the high-temperature debris from adhering to the surface of the intercepting rod 32, which is beneficial to the continuous use of the intercepting rod 32; improve the debris collection capacity of the receiving box 22; in addition, the harmful gases generated by laser cutting can also be extracted and transferred through the exhaust head 3 to optimize the air quality in the cutting operation area.

[0053] A guide tube 5 is provided at the end of the receiving box 22, and the end of the guide tube 5 located inside the receiving box 22 passes through the filter screen 33 and the cavity plate 4; the water vapor ejected through the cavity plate 4 will eventually fall and concentrate in the receiving box 22, and form liquid water, and then be guided out of the receiving box 22 through the guide tube 5.

[0054] Grooves 62 with the same shape and size as the teeth of the steel tooth plate 13 are provided on both sides of the material receiving box 22. A plurality of conductive heads 6 are provided through the top of the cavity plate 4. The bottom end of the conductive head 6 is connected to the cavity of the cavity plate 4. A nozzle 61 is provided on the top of the conductive head 6. Initially, the nozzle of the nozzle 61 points to the groove 62. When in use, the conductive head 6 can receive water vapor inside the cavity plate 4 and spray it out through the nozzle 61. The sprayed water vapor can enter the interior of the teeth of the steel tooth plate 13 through the groove 62 and wet the inner wall of the teeth of the steel tooth plate 13, thereby preventing high-temperature debris falling into the interior of the teeth of the steel tooth plate 13 from adhering to the teeth, thereby effectively limiting the accumulation of debris in the teeth of the steel tooth plate 13, which is beneficial to improving the service life of the steel tooth plate 13.

[0060] S5. When cutting is completed, the cut profiled metal plate is removed from the steel tooth plate 13.

[0061] During operation, when cutting, the metal plate is placed on the top of the steel tooth plate 13. As the laser cutting head 12 cuts the metal plate, the metal debris generated falls to the bottom of the metal plate and is then received by the receiving box 22. The receiving box 22 receives the high-temperature metal debris, effectively preventing the high-temperature metal debris from adhering to the surface of the steel tooth plate 13. After a period of use, the receiving box 22 can be disassembled and replaced. The receiving box 22 is made of plastic, which has low cost and can be used in large quantities. Therefore, a receiving box 22 can be set between adjacent steel tooth plates 13, which can effectively improve the service life of the steel tooth plates 13. A high-temperature resistant metal sheet is attached to the top of the receiving box 22. When the metal plate is placed on the top of the steel tooth plate 13, due to the above-mentioned receiving box, the metal plate is placed on the top of the steel tooth plate 13. The top of the box 22 is at the same height as the top of the steel tooth plate 13, so the top of the receiving box 22 can contact the bottom surface of the metal plate. When cutting the metal plate, the metal plate generates high temperature, and the top of the receiving box 22 is attached with a high-temperature resistant metal sheet, thereby improving the high-temperature resistance of the receiving box 22 and ensuring the use effect; the first connecting member 21 is specifically a hydraulic cylinder; the hydraulic cylinder housing is partially installed on the side of the positioning plate 2, and the output end of the hydraulic cylinder is connected to the receiving box 22; when in use, the hydraulic cylinder can drive the receiving box 22 to move back and forth between adjacent steel tooth plates 13, that is, the receiving box 22 continues to move relative to the steel tooth plate 13, preventing high-temperature debris from falling between the steel tooth plate 13 and the receiving box 22 and sticking the two together, so as to facilitate the subsequent removal of the receiving box 22.

[0062] When in use, the first air pump connected to the first air pipe 31 is started, and the first air pump evacuates the air to the exhaust head 3 through the first air pipe 31, and the exhaust head 3 evacuates the air to the receiving box 22, so that the fallen debris is concentrated in the receiving box 22, and adheres to the surface of the intercepting rod 32 when it contacts the intercepting rod 32 in the receiving box 22, thereby realizing the centralized collection of high-temperature debris and improving the collection effect; and the setting of the intercepting rod 32 can make the high-temperature debris at different positions quickly be taken over when falling into the receiving box 22, avoiding the high temperature debris under the action of airflow The debris is concentrated in one place, which affects the debris collection process; the interior of the receiving box 22 is provided with a filter 33, and the filter 33 is arranged at the air extraction port position of the exhaust head 3; by setting the filter 33, the exhaust head 3 can be prevented from sucking high-temperature debris into the interior, causing blockage of the exhaust head 3; when in use, the second air pump connected to the second air pipe 41 is started, and the second air pump fills the external water vapor into the cavity inside the cavity plate 4 through the second air pipe 41; then the water vapor is ejected upward through the air hole at the top of the cavity plate 4, so that it enters the receiving box The high-temperature debris inside 22 is quickly cooled and hardened, preventing the high-temperature debris from contacting the filter 33 and adhering to the surface of the filter 33, thereby clogging the filter 33; at the same time, the water vapor will wet the interception rod 32, preventing the high-temperature debris from adhering to the surface of the interception rod 32, which is beneficial to the continuous use of the interception rod 32; improving the collection capacity of the material receiving box 22 for debris; in addition, the harmful gases generated by laser cutting can also be extracted and transferred through the exhaust head 3, thereby optimizing the air quality in the cutting operation area; the water vapor ejected through the cavity plate 4 will finally fall and concentrate In the receiving box 22, liquid water is formed, and then it is guided out of the receiving box 22 through the guide tube 5; when in use, the conductive head 6 can receive the water vapor inside the cavity plate 4, and spray it out through the nozzle 61, and the sprayed water vapor can enter the interior of the steel tooth plate 13 teeth through the groove 62, and wet the inner wall of the steel tooth plate 13 teeth, thereby preventing high-temperature debris falling into the interior of the steel tooth plate 13 teeth from adhering to the teeth, thereby effectively limiting the accumulation of debris in the teeth of the steel tooth plate 13, which is beneficial to improving the service life of the steel tooth plate 13.
