By setting up the conveying structure, the transmission and export of slag-like structure metal waste is facilitated, and the classification and processing of block-like and slag-like structure metal door and window waste is facilitated, thereby improving the efficiency of the classification and export processing of waste to a certain extent.

[0034] Next, specifically describe the specific settings and functions of its material guiding structure 5, anti-stagnation structure 6 and conveying structure 7.

[0035] Such as Figures 1-8As shown, the material guide structure 5 also includes a rectangular block 508 fixedly connected to the side wall of the workbench 1. The rectangular block 508 is internally slidably connected to two limit bars 509. The upper ends of the two limit bars 509 are fixedly connected to a support plate 507. The support plate 507 is an isosceles triangle plate. The stopper 505 and the support plate 507 are in contact with each other. By lifting the support plate 507, the support work of multiple guide plates 502 can be lifted and supported at the same time. Both sides of the lifted multiple support plates 507 will form inclined surfaces to guide the block-shaped structure waste. The internal thread of the rectangular block 508 is connected to a screw rod 510. The screw rod 510 is internally rotatably connected to the support plate 507. The lower end of the screw rod 510 is fixedly connected to a hand wheel 511. By rotating the screw rod 510, the support plate 507 can be driven and lifted. Two horizontal bars 503 are fixedly connected to the inner side of the workbench 1, and the side walls of the two horizontal bars 503 are fixedly connected to a plurality of guide bars 514, and the side walls of the guide bars 514 are slidably connected to a slider 512, and a plurality of metal wires 504 are slidably penetrated inside the two horizontal bars 503, and the end sides of the metal wires 504 are fixedly connected to the slider 512, and the outer side of the metal wires 504 is sleeved with a first spring 513, and the two ends of the first spring 513 are respectively fixedly connected to the slider 512 and the horizontal bar 503. By providing the metal wires 504, firstly, the metal wires 504 can fall on the inner side of a plurality of rows of support frames 501, so that the support frames 501 and the metal wires 504 form a mesh structure after being lifted, further improving the screening effect of block structure waste and slag structure waste, and secondly, the metal wires 504 will be tightly attached to the upper side of the support frame 501 by the elastic force of the first springs 513 on both sides of the two support plates 507, thereby improving the stability of lifting or lowering the support plates 507. The surface of the guide plate 502 is evenly provided with a plurality of strip grooves 515, and the metal wire 504 is located inside the strip grooves 515. The setting of the guide plate 502 facilitates the work of guiding out the block-shaped waste material that slides off the support frame 501, and a collection box is placed at the port position of the guide plate 502 to realize the collection of the cut block-shaped waste material, and the setting of the strip grooves 515 facilitates the normal pulling and use of the metal wire 504 without affecting the use of the guide plate 502.

[0036] like Figures 1-3 and Figures 8-10As shown, the anti-retention structure 6 includes two drawers 62 slidably connected to the inside of the guide plate 502, a plurality of rectangular holes 64 are evenly opened on the surface of the guide plate 502, a plurality of protrusions 63 are evenly fixedly connected to the surface of the drawers 62, and the protrusions 63 are located on the inner side of the reserved holes, a fixed block 68 is fixedly connected to the side wall of the guide plate 502, and a second spring 67 is fixedly connected between the fixed block 68 and the drawers 62. After the material guiding is completed, when the block-shaped sheet material is retained on the guide plate 502, the drawers 62 can be pulled to achieve the relative driving of the plurality of protrusions 63 on the inner side of the rectangular holes 64, thereby avoiding the block-shaped sheet material being retained on the guide plate 502. Both sides of the support plate 507 are fixedly connected with moving bars 61, and the side of the moving bar 61 away from the support plate 507 is a tooth-shaped structure. By providing the moving bar 61 with a toothed structure, the moving bar 61 will move simultaneously in the process of driving the support plate 507 to move downward. At this time, the moving bar 61 with a toothed structure will move relative to the lower position of the draw plate 62, thereby facilitating the reciprocating movement of the draw plate 62 inside the guide plate 502. The second spring 67 is provided here to facilitate the movement of the draw plate 62 toward the side close to the guide plate 502, thereby realizing the reciprocating movement of the draw plate 62. Both sides of the draw plate 62 are fixedly connected with connecting wheels 65, and the side walls of the connecting wheels 65 are rotatably connected with rollers 66, and the rollers 66 are opposite to the side of the moving bar 61 with the toothed structure. The moving bar 61 and the rollers 66 move relative to each other, thereby reducing the friction force when the moving bar 61 and the draw plate 62 move relative to each other.

[0037] like Figures 1-3 and Figure 9 As shown, a conveying structure 7 is provided inside the workbench 1. The conveying structure 7 includes two first connecting plates 72 fixedly connected to both sides of the workbench 1. The two first connecting plates 72 are internally connected to driven wheels 73 for rotation. Two second connecting plates 74 are fixedly connected to the side wall of the workbench 1. The two second connecting plates 74 are internally connected to driving wheels 75 for rotation. The driving wheels 75 and the side walls of the driven wheels 73 are connected to the conveyor belt 71 for transmission. A mounting plate 78 is fixedly connected to the side wall of the workbench 1. A mounting ring 76 is fixedly connected to the other end of the mounting plate 78. A motor 77 is fixedly installed inside the mounting ring 76. The output end of the motor 77 is fixedly connected to the driving wheel 75. The motor 77 is started, and the motor 77 drives the driving wheel 75 to operate, so as to realize the conveying work of the driving wheel 75 and the driven wheel 73 on the conveyor belt 71, thereby realizing the work of exporting the slag-like structure cutting waste on the surface of the conveyor belt 71. The driving wheel 75 and the driven wheel 73 are both spliced by a round rod and two round tables. By providing the driving wheel 75 and the driven wheel 73 with a truncated cone structure on both sides, the phenomenon of the slag falling into the inner side of the gap between the conveyor belt 71 and the inner side of the workbench 1 is avoided, and the efficiency of the slag discharge is further improved.

[0038] Working principle: When using this thermal cutting device for metal doors and windows processing, first place the metal doors and windows to be cut on the workbench 1, start the laser cutting head 4, and drive the driving frame 2 to slide on the surface of the workbench 1, driving the moving frame 3 and the laser cutting head 4 to move, so as to realize the cutting operation of the metal doors and windows. The waste generated by cutting will fall on the support frame 501. The upper surface of the support frame 501 is a toothed structure. This design is conducive to the dispersion and screening of waste. When it is necessary to clean the waste, rotate the handwheel 511. The handwheel 511 drives the screw rod 510 to rotate. The screw rod 510 is rotatably connected to the support plate 507, and the screw rod 510 is threadedly connected in the rectangular block 508. Therefore, the rotation of the screw rod 510 will drive the support plate 507 to rise. Since the stopper 505 is in contact with the support plate 507, the rise of the support plate 507 will push the support frame 501 to rise together. The metal wire 504 falls inside several rows of support frames 501, forming a mesh structure with the support frame 501. This mesh structure can more effectively screen the waste in block structure and slag structure. The block waste remains on the support frame 501, while the slag waste falls through the toothed gaps of the support frame 501 and the gaps between the metal wires 504. The diversion plate 502 is arranged inside the workbench 1. By setting the metal wire 504, firstly, the metal wire 504 can fall inside several rows of support frames 501, so that a mesh structure is formed after the support frame 501 and the metal wire 504 are lifted, further improving the screening effect on the waste in block structure and slag structure. Secondly, the metal wire 504 will be tightly attached to the upper part of the support frame 501 under the elastic force of the first springs 513 on both sides of the two support plates 507, improving the stability of lifting or lowering the support plate 507. Its function is to guide the block waste sliding from the support frame 501. A number of strip-shaped grooves 515 are evenly arranged on the surface of the diversion plate 502. The metal wire 504 is located inside the strip-shaped grooves 515. The design of the strip-shaped grooves 515 neither affects the guiding effect of the diversion plate 502 on the block waste nor facilitates the normal extraction of the metal wire 504. Place a collection box at the port position of the diversion plate 502. The block waste sliding from the support frame 501 will directly fall into the collection box along the inclined surface of the diversion plate 502, realizing the convenient collection of the block waste. By setting the material guiding structure 5, it facilitates the flexible material guiding work of the waste, avoids the phenomenon of manual frequent collection of the cut block waste on the support frame 501, improves the processing efficiency of the cut block waste as much as possible, and improves the use performance of the thermal cutting device to a certain extent.

[0039] If there is a situation where blocky sheet materials are retained on the diversion plate 502 during the material guiding process, the anti-retention structure 6 will come into play. When the support plate 507 moves downward, the moving strips 61 fixedly connected to both sides thereof will move synchronously. The side of the moving strip 61 away from the support plate 507 is a toothed structure, and this toothed structure undergoes relative movement with the lower side of the extraction plate 62. The extraction plate 62 is slidably connected inside the diversion plate 502. A number of bumps 63 are evenly and fixedly connected to the surface of the extraction plate 62. The bumps 63 are located inside the rectangular holes 64 formed on the surface of the diversion plate 502. The second spring 67 is provided to facilitate the movement of the extraction plate 62 toward the side close to the diversion plate 502, thereby realizing the reciprocating pumping work of the extraction plate 62. Driven by the moving strip 61, the extraction plate 62 reciprocates inside the diversion plate 502, and the bumps 63 on the extraction plate 62 move inside the rectangular holes 64, pushing the retained blocky sheet materials off the diversion plate 502, preventing the blocky sheet materials from accumulating and retaining on the diversion plate 502. In addition, rollers 66 are rotatably connected to the connecting wheels 65 fixedly connected to both sides of the extraction plate 62. The rollers 66 face the side of the moving strip 61 with the toothed structure. The setting of the rollers 66 reduces the frictional force during the relative movement between the moving strip 61 and the extraction plate 62, making the pumping of the extraction plate 62 smoother. By setting the anti-retention structure 6, the phenomenon of blocky waste of metal doors and windows remaining on the diversion plate 502 is avoided, further improving the export efficiency of the metal blocky waste.

[0040] After collecting the metal blocky structural waste, for the slag-like waste that falls after screening, first place a collection box at the conveyor belt output position. Start the motor 77. The motor 77 is installed inside the mounting ring 76. The mounting ring 76 is fixed to the side wall of the workbench 1 through the mounting plate 78. The output end of the motor 77 is fixedly connected to the driving wheel 75. The operation of the motor 77 drives the driving wheel 75 to rotate. The driving wheel 75 and the driven wheel 73 are respectively rotatably connected to both sides of the workbench 1 through the first connecting plate 72 and the second connecting plate 74. The side walls of the driving wheel 75 and the driven wheel 73 are drivingly connected with a conveyor belt 71. The rotation of the driving wheel 75 drives the conveyor belt 71 to move. The driven wheel 73 plays an auxiliary driving role to make the conveyor belt 71 run smoothly. Both the driving wheel 75 and the driven wheel 73 are composed of a round rod and two frustums spliced together. This structural design avoids slag falling into the gap between the conveyor belt 71 and the inside of the workbench 1, ensuring that the slag-like waste can be smoothly conveyed by the conveyor belt 71 to the designated position, realizing the centralized export treatment work of the slag-like cutting waste. By setting the conveying structure 7, it facilitates the conveying and export work of the slag-like structural metal waste, facilitates the classification treatment work of the blocky and slag-like structural metal door and window waste, and improves the classification export treatment efficiency of the waste to a certain extent.
