[0014] A method for using a laser cutting device for processing metal doors and windows includes the following steps: Step 1: The worker places the original metal door and window panel on the conveyor belt. The worker then adjusts the sliding frame according to the required length of the original metal door and window panel to be cut, starts the conveyor belt, and starts the motion device. When the motion device moves downward, it drives the bidirectional free telescopic rod to move. When the bidirectional free telescopic rod moves, it drives the telescopic column to move.

Step 2: The worker pulls the elastic telescopic strip outward. When the elastic telescopic strip moves outward, it will drive the limiting block to move. When the limiting block moves, it will release the limitation on the sliding frame. When the limitation on the sliding frame is released, the worker pulls the sliding frame to the position that is suitable for the original metal door and window panel. When the position is appropriate, the elastic telescopic strip is released. After the elastic telescopic strip is released, it will continue to limit the sliding frame. Step 3: When the output end of the motion device moves, it will drive the bidirectional free telescopic rod to move. When the bidirectional free telescopic rod moves, it will drive the fixed column to move. When the fixed column moves, it will drive the elastic telescopic rod to move. When the elastic telescopic rod moves, it will press down on the moving metal door and window original panel to prevent the metal door and window original panel from shaking randomly during cutting, which would affect the cutting accuracy.

[0015] This invention provides a laser cutting device for processing metal doors and windows. It has the following beneficial effects: (1) This invention, through the adjustment of the sliding frame and the fixing of the limiting block, can accurately set the cutting length of the original metal door and window panel according to the requirements. The blocking effect of the stop bar can ensure that the position of the panel is consistent each time it is cut. The elastic telescopic rod squeezes and fixes the panel, avoiding the size deviation caused by shaking during the cutting process. Finally, it achieves the consistency of length during batch cutting and improves the standardization of the product.

[0016] (2) This invention can directly press the cutting parts off the scrap by pressing down the pressure column, thereby achieving rapid separation of the two, avoiding the tediousness of manual separation, improving processing efficiency, and using the vibration generated by the contact between the rack and the spring plate to drive the disc to vibrate, which can shake off the hanging cutting parts, prevent the cutting parts from remaining on the scrap, ensure thorough separation, and reduce the trouble of subsequent processing.

[0017] (3) In this invention, when the original metal door and window panel falls off the push post, the elastic telescopic buffer post will contact the original panel and use its own elasticity to buffer the falling process, reducing the possibility of damage to the original panel due to collision. Through the linkage of a series of components such as push post, U-plate, elastic telescopic buffer post, L-rod, rounded corner post, push block, and slider, the problem of the original metal door and window panel falling into the collection box at one end first and being placed at an angle is solved, and finally it is placed flat at the bottom of the collection box, which is convenient for subsequent sorting and processing.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8 One embodiment of the present invention is: a laser cutting device for processing metal doors and windows, including a main frame 1, an auxiliary device for cutting the original metal door and window panels to the same length, including an equidistant device, and the equidistant device further includes; Conveyor belt 2 is installed inside the main frame 1. Motion device 3 is fixedly installed on the top of the main frame 1. A laser cutting device is installed at the output end of motion device 3. A collection box 4 is fixedly installed on the left side of the main frame 1. A sliding groove is opened on the surface of the collection box 4. A bidirectional free telescopic rod 501 is provided. One end of the bidirectional free telescopic rod 501 is fixedly installed at the output end of the motion device 3. A fixed column 502 is fixedly installed in the middle of the bidirectional free telescopic rod 501. An elastic telescopic rod 503 is fixedly installed at the bottom of the fixed column 502. The elastic telescopic rod 503 is used to press down the original metal door and window panel to prevent it from shaking during cutting. Telescopic column 504, the fixed end of telescopic column 504 is fixedly installed at the other end of bidirectional free telescopic rod 501, and the free end of telescopic column 504 is fixedly installed with a stop bar 506, which is used to block the original metal door and window panel. The connecting column 507 has one end fixedly installed on the left side of the main frame 1, and the other end of the connecting column 507 has a sliding frame 508 slidably installed on its outer surface. The sliding frame 508 is used to control the length of the original metal door and window panel. The elastic telescopic rod 503 squeezes and fixes the panel, avoiding dimensional deviations caused by shaking during the cutting process, and ultimately achieving length consistency during batch cutting, thus improving the standardization of the product.

[0023] The equidistant device also includes a long column 505, an elastic telescopic strip 509, and a limiting block 510. The long column 505 is fixedly installed on the top of the sliding frame 508. A groove is provided on the side of the long column 505 near the stop bar 506. The stop bar 506 is slidably installed with the long column 505. The fixed end of the elastic telescopic strip 509 is fixedly installed on the front of the main frame 1. The limiting block 510 is fixedly installed on the free end of the elastic telescopic strip 509. After the sliding frame 508 is adjusted, the elastic telescopic strip 509 is released. When the elastic telescopic strip 509 is released from its limiting position, it will move the limiting block 510 towards the sliding frame 508 due to its own elasticity. When the limiting block 510 contacts the sliding frame 508, it will limit the sliding frame 508.

[0024] The limiting block 510 contacts the sliding frame 508, the stop bar 506 contacts the sliding frame 508, the sliding frame 508 has a slot on the front, the bidirectional free telescopic rod 501 is telescopic, so it can be ensured that the bidirectional free telescopic rod 501, the telescopic column 504 and the stop bar 506 can always be connected. After adjustment, the original metal door and window panel is placed on the conveyor belt 2 inside the main frame 1.

[0025] In this embodiment, during operation: the operator first adjusts the sliding frame 508 on the connecting column 507. When the elastic telescopic bar 509 is pulled outward, it moves the limiting block 510. When the limiting block 510 moves, it releases the restriction on the sliding frame 508. When the restriction on the sliding frame 508 is released, the operator adjusts the sliding frame 508 to the length of the original metal door and window panel to be cut. After adjusting the sliding frame 508, the elastic telescopic bar 509 is released. After the telescopic bar 509 is released from its limit, it will cause the limit block 510 to move closer to the sliding frame 508 due to its own elasticity. When the limit block 510 contacts the sliding frame 508, it will limit the sliding frame 508. When the sliding frame 508 moves, it will cause the long column 505 to move. When the long column 505 moves, it will cause the stop bar 506 to move. Since the bidirectional free telescopic bar 501 is telescopic, it can ensure that the bidirectional free telescopic bar 501, the telescopic column 504, and the stop bar 506 can always remain connected. After adjustment, place the original metal door and window panel on the conveyor belt 2 inside the main frame 1. Start the conveyor belt 2 and the motion device 3. When the motion device 3 moves downward, it will drive the bidirectional free telescopic rod 501 to move. When the bidirectional free telescopic rod 501 moves, it will drive the elastic telescopic rod 503 to move. When the elastic telescopic rod 503 moves, it will drive the stop rod 506 to slide inside the long column 505. When the stop rod 506 moves to the bottom of the long column 505, the telescopic column 504 will retract to prevent it from affecting the stop rod 506. When the stop rod 506 moves to the bottom, it will block the original metal door and window panel moving on the conveyor belt 2. When the bidirectional free telescopic rod 501 moves, it will drive the fixed column 502 to move. When the fixed column 502 moves, it will drive the elastic telescopic rod 503 to move. When the elastic telescopic rod 503 moves, it will squeeze the blocked original metal door and window panel to prevent shaking during the laser cutting machine at the bottom of the motion device 3, which would affect the cutting accuracy.

[0026] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the top of the collection box 4 is provided with a pressing device for separating the cut metal door and window original panels from the cut scraps, and the inside of the collection box 4 is provided with an aligning device for recycling the cut scraps. The pressing device includes a pressure plate 601, a square plate 602, a force plate 603, a pressure column 604, a rotating column 605, and a disc 606.

By means of the vibration generated by the contact between the rack 609 and the spring plate 607, the disc 606 is driven to vibrate, which can shake off the cut parts hanging on the edge, prevent the cut parts from remaining on the scraps, ensure thorough separation, and reduce the trouble of subsequent processing.

[0027] The pressing device also includes a spring plate 607, a block 608, and a rack 609. The spring plate 607 is fixedly installed on the side of the disc 606 away from the rotating column 605.

When the pressing column 604 presses down, it will push the cutting part off the scrap. When the force plate 603 moves, it will drive the block 608 to move. When the block 608 moves, it will drive the rack 609 to move. When the rack 609 moves, it will contact the spring plate 607.

[0028] The rack 609 contacts the spring plate 607, the pressure column 604 contacts the original metal door and window panel, a No. 1 spring is provided between the force plate 603 and the square plate 602, and the pressure plate 601 contacts the force plate 603. When the rack 609 contacts the spring plate 607, the spring plate 607 will vibrate. When the spring plate 607 vibrates, it will drive the disc 606 to vibrate.

[0029] The alignment device includes a transmission plate 701, an inclined plate 702, an arc plate 703, a pusher 704, an elastic telescopic buffer column 705, a U-plate 706, an L-bar 707, a rounded corner column 708, a push block 709, and a slider 710. One end of the transmission plate 701 is fixedly installed on the side of the force plate 603 near the block 608, and the inclined plate 702 is fixedly installed on the other end of the transmission plate 701. The pusher 704 rotates through the inner wall of the collection box 4, and the arc plate 703 is fixedly installed on the circumferential surface of the pusher 704. The fixed end of the elastic telescopic buffer column 705 is slidably installed. At the bottom of the inner wall of the collection box 4, the U-plate 706 is slidably installed on the top of the free end of the elastic telescopic buffer column 705. One end of the L-rod 707 is fixedly installed on the circumferential surface of the push column 704. The rounded corner column 708 is fixedly installed on the other end of the L-rod 707. The push block 709 is fixedly installed on the side of the rounded corner column 708 near the collection box 4. The slider 710 is set inside the sliding groove of the collection box 4, which solves the problem of the original metal door and window panel falling into the collection box 4 at one end first and being placed at an angle. Finally, it is placed flat at the bottom of the collection box 4, which is convenient for subsequent sorting and processing.

[0030] Push block 709 contacts slider 710, rounded corner post 708 contacts slider 710, a second spring is provided between slider 710 and the sliding groove of collection box 4, push post 704 contacts U plate 706, when sliding to a certain distance, U plate 706 will drive elastic telescopic buffer post 705 to slide at the bottom of the inner wall of collection box 4, when push post 704 moves, it will drive L rod 707 to move, when L rod 707 moves, it will drive rounded corner post 708 to move.

[0031] In this embodiment, after the original metal door and window panel is cut, it is transported by the main frame 1 to the rotating column 605 and the disc 606. The pressure column 604 at the bottom of the force plate 603 is adjusted according to the cutting position. When the stop bar 506 moves, it will drive the pressure plate 601 to move. When the pressure plate 601 moves, it will drive the force plate 603 on the square plate 602 to move. When the force plate 603 moves, it will drive the pressure column 604 at the bottom of the force plate 603 to move. When the pressure column 604 moves, it will separate the cut parts and scraps of the original metal door and window panel on the disc 606. When the pressure column 604 presses down, it will push the cut parts off the scraps. When the force plate 603 moves, it will drive the block 608 to move. When the block 608 moves, it will drive the rack 609 to move. When the rack 609 moves, it will come into contact with the spring plate 607. When the rack 609 comes into contact with the spring plate 607, it will cause the spring plate 607 to vibrate. When the spring plate 607 vibrates, it will drive the disc 606 to vibrate. When the disc 606 vibrates, it will shake off the cutting parts hanging on the edge.

[0032] When the next metal door / window panel enters the top of the rotating column 605, it pushes the previous one, causing it to fall into the collection box 4. Since the metal door / window panel falls into the collection box 4 at one end first, it will be placed at an angle inside the collection box 4. When the force plate 603 moves, it drives the transmission plate 701. When the transmission plate 701 moves, it drives the inclined plate 702. When the inclined plate 702 moves, it drives the arc plate 703. When the arc plate 703 moves, it drives... The push column 704 moves, which in turn moves the U-plate 706. The U-plate 706 first slides on the top of the free end of the elastic telescopic buffer column 705. After sliding a certain distance, the U-plate 706 moves the elastic telescopic buffer column 705 against the bottom of the inner wall of the collection box 4. The movement of the push column 704 then moves the L-rod 707, which in turn moves the rounded corner column 708, which in turn moves the push block 709. When the rounded corner post 708 moves, it first pushes the slider 710 towards the elastic telescopic buffer post 705. As the rounded corner post 708 continues to move, it causes the push block 709 to contact the slider 710. After the push block 709 contacts the slider 710, it will drive the slider 710 to move. When the slider 710 moves, it will cause one end of the original door and window panel to slide near the bottom of the inner wall of the collection box 4. At the same time, the push post 704 is also moving, so one end of the original door and window panel will move to the far left of the collection box 4. When moving in the opposite direction, the U-plate 706 will move first. At this time, the original door and window panel will disengage from the push post 704 and fall down. However, the elastic telescopic buffer post 705 has not yet moved, so the original door and window panel will contact the elastic telescopic buffer post 705. The elastic telescopic buffer post 705 will cushion the fall of the original door and window panel. The movement of the rounded corner post 708 will release the limit of the slider 710, so the slider 710 will leave the bottom of the original door and window panel. At this time, the original door and window panel will be placed flat on the bottom of the collection box 4.

[0033] A method for using a laser cutting device for processing metal doors and windows includes the following steps: Step 1: The worker places the original metal door and window panel on the conveyor belt 2, and adjusts the sliding frame 508 according to the required length of the original metal door and window panel to be cut. The worker starts the conveyor belt 2 and the motion device 3. When the motion device 3 moves downward, it will drive the bidirectional free telescopic rod 501 to move. When the bidirectional free telescopic rod 501 moves, it will drive the telescopic column 504 to move. When the telescopic column 504 moves, it will drive the stop bar 506 to move. When the stop bar 506 moves, it will block the original metal door and window panel to facilitate cutting. Step 2: The worker pulls the elastic telescopic strip 509 outward. When the elastic telescopic strip 509 moves outward, it will drive the limiting block 510 to move. When the limiting block 510 moves, it will release the limitation on the sliding frame 508. When the limitation on the sliding frame 508 is released, the worker pulls the sliding frame 508 to a position that is suitable for the required length of the original metal door and window panel. When the position is appropriate, the elastic telescopic strip 509 is released. After the elastic telescopic strip 509 is released, it will continue to limit the sliding frame 508. Step 3: When the output end of the motion device 3 moves, it will drive the bidirectional free telescopic rod 501 to move. When the bidirectional free telescopic rod 501 moves, it will drive the fixed column 502 to move. When the fixed column 502 moves, it will drive the elastic telescopic rod 503 to move. When the elastic telescopic rod 503 moves, it will press down the moving metal door and window original panel to prevent the metal door and window original panel from shaking randomly during cutting, which would affect the cutting accuracy.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
