[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Reference Manual Attached Figure 1 and Figure 2 As shown, an environmentally friendly laser cutting equipment for recycling scrap metal includes: a first conveyor line 1 and a second conveyor line 2, the first conveyor line 1 and the second conveyor line 2 are arranged parallel to each other, and the first conveyor line 1 and the second conveyor line 2 are both arranged on a frame and extend along a preset direction to carry and convey metal.

[0024] A conveying mechanism is set up, and the first conveying line 1 and the second conveying line 2 distributed up and down, in conjunction with the U-shaped tube 40, can realize automatic surface changing of the metal plate, which is beneficial to the cleaning of both sides of the metal plate and improves the cutting quality. At the same time, the limit plate 41 on the second conveying line 2 can effectively prevent the sliding metal plate from deviating from the conveying track, thereby improving the stability of the device transportation.

[0025] The first cleaning and pressing mechanism 3 includes a first motor 4 placed on the first conveyor line 1, the output shaft of the first motor 4 passes through the first conveyor belt 5 and extends to the second conveyor belt 6, one end of the second conveyor belt 6 is connected to the first rotating wheel 7, one end of the first rotating wheel 7 passes through the side plate and extends to the first cleaning roller 8; wherein, one end of the first conveyor belt 5 is connected to the second rotating wheel 9, one end of the second rotating wheel 9 is fixedly connected to the pressure roller 10, and the other end is connected to the lifting block 11 symmetrical with the center of the first conveyor line 1, and the outer wall edge of the second rotating wheel 9 is provided with a rolling groove connected to the lifting block 11, and the bottom of the lifting block 11 is connected to the extension part of the frame through the first spring 12.

[0026] A first cleaning and pressing mechanism 3 is provided. After the first motor 4 is started, it can drive the first cleaning roller 8 on the first rotating wheel 7 to perform reverse rotation and cleaning work on the metal plate. At the same time, it can transmit power to the first conveyor belt 5, and drive the pressing roller 10 on the second rotating wheel 9 to rotate. In conjunction with the first spring 12 connected to the lifting block 11, the metal plate can be pressed on metal plates of different thicknesses when passing through the pressing roller 10, so that the metal plate that is bent to a certain extent can be adjusted to a flat state, which is conducive to subsequent precise cutting work and improves product quality.

[0027] Specifically, the first motor 4 and the second motor 21 corresponding to the first conveyor line 1 and the second conveyor line 2 can not only drive their respective transmission parts to move through the motors, but also drive the transmission rollers on the conveyor lines to rotate. The movement between the transmission rollers is realized through the sprocket chain assembly to achieve transmission connection, thereby achieving transmission connection between the transmission rollers. In this way, the metal plates can be smoothly transported on the conveyor lines. The above-mentioned sprocket chain assembly is a conventional technical means for technical personnel in this field, so it is not shown in the drawings, but it does not affect the effective implementation of the technical solution of the present invention.

[0028] The first conveyor line 1 and the second conveyor line 2, which are arranged parallel to each other, are mainly used to cooperate with the U-shaped tube 40 to perform the surface changing work, which is beneficial to the cleaning of both sides of the metal plate. In this way, the metal plate can be effectively cleaned while being turned over, which is beneficial to improving the subsequent cutting quality. Through the reverse rotation cleaning work, the friction on the surface of the metal plate can be increased to improve the cleaning effect.

[0029] refer to Figure 1 , Figure 4 and Figure 5 , the tensioning adjustment mechanism 13, the tensioning adjustment mechanism 13 includes a bending rod 14 fixed to one end of the lifting block 11, one end of the bending rod 14 passes through the cover body and is connected to the first guide wheel 16 placed between the first conveyor belts 5 through the pushing assembly 15, and the tensioning adjustment mechanism 13 is used to adjust the tension of the first conveyor belt 5 when it is transmitted.

[0030] Specifically, the pushing assembly 15 includes a lower gear plate 17 fixed on the bending rod 14, the outer wall of the lower gear plate 17 is meshed with a reverse-moving upper gear plate 19 through a central gear 18, and the extension of one end of the upper gear plate 19 is connected to the first guide wheel 16 through a bracket, and the bending rod 14 and one end of the bracket are connected with a strip groove along the height direction of the cover body.

[0031] A tension adjustment mechanism 13 is provided. When the lifting block 11 moves downward, the transmission distance of the first conveyor belt 5 becomes shorter and becomes loose. In order to ensure the normal tension of the first conveyor belt 5, the lifting block 11 can drive the lower gear plate 17 to move downward. Under the gear meshing transmission action, the upper gear plate 19 can be driven to move upward, and the top surface of the first conveyor belt 5 is driven upward through the first guide wheel 16, thereby increasing the transmission distance, so that the first conveyor belt 5 can perform normal transmission work. On the contrary, the first guide wheel 16 drives the bottom surface of the first conveyor belt 5 to move downward, thereby reducing the transmission distance, so that the first conveyor belt 5 maintains a normal tension, thereby improving the stability of the device operation.

[0032] The pushing component 15 essentially adjusts the tension of the first conveyor belt 5 through the gear component and the first guide wheel 16, so that the first conveyor belt 5 always maintains a relatively normal transmission tension, and then the power can be effectively transmitted to the second rotating wheel 9. The rotating shaft on the central gear 18 is connected to the side wall of the cover body through a bearing, and the outer wall of the cover body is installed on the frame by locking and fixing with a positioning bolt. The installation and connection by locking and fixing with a positioning bolt is conducive to quickly fixing the cover body on the frame, and is convenient for installation and disassembly work by personnel, and is convenient for personnel maintenance.

[0033] refer to Figure 3 , Figure 6 , Figure 7 and Figure 8 An environmentally friendly laser cutting device for recycling scrap metal also includes a second cleaning guide mechanism 20, which includes a second motor 21 placed on the second conveyor line 2, and the output shaft of the second motor 21 passes through the third conveyor belt 22 and extends to the fourth conveyor belt 23. One end of the fourth conveyor belt 23 is transmission-connected with a third rotating wheel 24, one end of the third rotating wheel 24 is connected to the second cleaning roller 25, and a retaining ring is fixedly installed relative to the other end.

[0034] One end of the third conveyor belt 22 is transmission connected to the fourth rotating wheel 26, and the fourth rotating wheel 26 and the transition wheel 27 at the same height are transmission connected by the fifth conveyor belt 28. The inner wall of the transition wheel 27 is fixed on the reciprocating screw 29, and both ends of the reciprocating screw 29 are spirally driven with a first slider 30 that moves in the opposite direction. One end of the first slider 30 is fixedly connected to a panel via a second spring 31, and the bottom of the panel is movably connected to a second guide wheel 32 placed on the second conveyor line 2.

[0035] A second cleaning guide mechanism 20 is provided. After the second motor 21 is started, it can drive the second cleaning roller 25 on the third rotating wheel 24 to rotate in the opposite direction to clean the other end surface of the metal plate, and can transmit power to the fourth rotating wheel 26 through the third conveyor belt 22. Through the transition adjustment of the fifth conveyor belt 28, the power can be stably transmitted to the transition wheel 27 and drive the rotation of the reciprocating screw 29. Under the action of the spiral transmission, the second guide wheel 32 can be driven to move back and forth in a centering manner, so that the metal plate can be accurately transmitted and transported on the second conveyor line 2, avoiding the phenomenon of deviation from the track, and ensuring the safety of the metal plate transportation work.

[0036] The fourth rotating wheel 26 and the transition wheel 27 are mainly provided to smoothly transmit power to the reciprocating screw 29. If the power is directly transmitted to the reciprocating screw 29 through the conveyor belt, on the one hand, the transmission distance is too long, which may lead to loose and unstable transmission. On the other hand, the output shaft of the second motor 21 needs to be adaptively increased and adjusted to correspond to the protruding part of the reciprocating screw 29. This will give the frame a corresponding load-bearing load, which is not conducive to improving the safety of the device. The outer wall of the fourth rotating wheel 26 is connected by a guide ring 33 fixed to the frame, and the outside of the reciprocating screw 29 and the transition wheel 27 are placed in a fixed block installed on the frame and having a slot.

[0037] The guide ring 33 on the frame not only provides support for the fourth rotating wheel 26, but also enables the fourth rotating wheel 26 to rotate normally. The retaining ring on the third rotating wheel 24 can be fixedly connected with the third rotating wheel 24 by a threaded connection, and the retaining ring can effectively prevent the fourth conveyor belt 23 from deviating from its position during the transmission process, thereby ensuring the stable rotation of the fourth conveyor belt 23 on the third rotating wheel 24.

[0038] refer to Figure 1 and Fig. 9A third motor 34 is installed on the second conveyor line 2 through a cross beam, and the output shaft of the third motor 34 is connected to a screw shaft 35. A second slider 36 is spirally transmitted on the screw shaft 35. A laser 38 is installed at the bottom of the second slider 36 through a cylinder 37, and baffles 39 are installed at both ends of the piston rod on the cylinder 37 through fixed rods. The first conveyor line 1 and the second conveyor line 2 are connected by a U-shaped tube 40, and a limit plate 41 is fixedly installed on the frame on the second conveyor line 2 near the U-shaped tube 40.

[0039] As the piston rod on the cylinder 37 moves downward, it can drive the laser 38 to reach a suitable cutting point, and can drive the baffle 39 to move downward synchronously, so that the baffle 39 can be used to limit the two ends of the metal plate to prevent shaking during the cutting operation. By extension, the baffle 39 can be set to be telescopic in the plane direction, so that it can be adaptively telescopically adjusted according to the end face size of different metal plates, thereby effectively limiting the two ends of the metal plate.

[0040] refer to Fig.10 , an environmentally friendly laser cutting method for recycling scrap metals, comprising the following steps: S1.1. Place the metal on the first conveyor line 1 for transmission and conveying. The first motor 4 is started and drives the first cleaning roller 8 to rotate in the opposite direction for cleaning. The pressing roller 10 can press the metals of different heights and adjust their flatness under the action of the first spring 12. S1.2. The metal is re-faced through the U-shaped tube 40, the second motor 21 is started and drives the second cleaning roller 25 to rotate in the opposite direction for cleaning, and cooperates with the second guide wheel 32 on the first slider 30 so that the second guide wheel 32 moves in the center and pushes and guides the metal to prevent the position from deviating during the conveying process; S1.3, the cylinder 37 moves the laser 38 to the corresponding height, and limits the metal through the baffles 39 at both ends, and cooperates with the screw shaft 35 on the third motor 34 to achieve laser cutting of the metal under the action of spiral transmission.

[0041] The entire laser cutting method is reasonably designed and has strong integrated performance. It can automatically clean the surface of the metal plate with good cleaning effect. It can also press and flatten the bent metal plate to ensure its flatness. While ensuring the effective centering and transportation of the metal plate, the cutting quality of the laser 38 is improved.
