A laser cutting machine that can automatically clean up waste.

Abstract

This invention relates to the field of laser cutting machine technology, and more particularly to a laser cutting machine capable of automatically cleaning waste. It includes a U-shaped plate and a base frame symmetrically fixed to the U-shaped plate. A guide frame for collecting waste and waste liquid is fixed to the outer side of the U-shaped plate. Movable blocks are slidably connected to both the left and right sides of the U-shaped plate, and a laser cutting head is positioned between the two movable blocks. In this invention, the sheet material is placed on the support frame, and then the laser cutting head is activated and moved forward to the cutting position. Simultaneously, a trigger plate drives a single-hole piston rod upward via rollers, causing water in the inlet pipe to drain into the guide pipe. The water in the guide pipe is slowly sprayed out through a nozzle, flowing on the support frame to form a water flow layer. When the laser cutting head cuts the sheet material, the waste falling off is removed by the water flow layer, preventing waste from adhering to the support frame and clumping, which could scratch subsequently placed sheet material, thus ensuring the integrity and quality of the sheet material.

Description

Technical Field

[0001] This invention relates to the field of laser cutting machine technology, and in particular to a laser cutting machine that can automatically clean up waste materials. Background Technology

[0002] During the processing of sheet materials, they need to be cut to the required shape before further processing. To achieve higher cutting precision and smoother cuts, laser cutting machines are used. However, laser cutting machines generate waste material during the cutting process.

[0003] Currently, in the existing technology of using a laser cutting machine to cut sheet materials, the sheet material needs to be placed on a support frame for laser cutting. However, because the laser head emits high heat when cutting the sheet material, the high heat can easily cause waste material to be generated during the cutting process. The waste material affected by the high temperature is prone to adhering to the support frame and clumping, which can easily scratch the sheet material placed later and affect the integrity and quality of the sheet material.

[0004] Therefore, there is a need to design a laser cutting machine that can automatically clean up waste materials to prevent them from adhering and scratching the sheet metal, thus ensuring the integrity of the sheet metal. Summary of the Invention

[0005] To overcome the drawbacks of high heat generated during laser cutting, which can lead to waste material buildup and adhesion to the support frame, potentially scratching subsequent sheet materials and affecting their integrity, this invention provides a laser cutting machine that can automatically remove waste material to prevent it from scratching the sheet and ensuring its integrity.

[0006] This invention is achieved through the following technical means:

[0007] A laser cutting machine capable of automatically cleaning waste includes a U-shaped plate and a base frame symmetrically fixed to the U-shaped plate. A guide frame for collecting waste and waste liquid is fixed to the outer side of the U-shaped plate. A laser cutting head is mounted on the U-shaped plate, with movable blocks fixed to both sides of the laser cutting head. A support frame for supporting and placing the sheet material is mounted on the U-shaped plate. The machine also includes guide pipes, a water inlet pipe, a spray pipe, a connecting component, and a material blocking component. The guide pipes are evenly spaced and fixedly connected to the support frame. Laterally, the guide pipes... The system is equipped with evenly spaced nozzles that penetrate the support frame. A water inlet pipe, which is connected to and communicates with the guide pipe, is fixed inside the molded plate. The connecting component is installed between the movable block and the guide pipe. The connecting component is used to control the water in the water inlet pipe to flow into the guide pipe, and then the water in the guide pipe flows into the nozzle. The nozzle sprays water onto the support frame, so that the water flows on the support frame to remove falling waste. The material blocking component is installed between the molded plate and the laser cutting head to block the waste ejected during the laser cutting process.

[0008] To further explain, the bottom of the guide frame is a slope, and the slope of the guide frame slopes downward from left to right.

[0009] Further explanation: the connecting component includes a single-hole piston rod that is slidably connected to the guide tube. The hole of the single-hole piston rod is horizontally arranged. A connecting spring is connected between the single-hole piston rod and the guide tube. A trigger plate is fixed on one of the movable blocks to drive the single-hole piston rod to move upward.

[0010] To further explain, the front and rear sides of the trigger plate are inclined surfaces, and the inclined surfaces of the trigger plate are tilted towards the direction of the guide tube and close to its own center.

[0011] To further explain, a roller is rotatably connected to the bottom end of the single-hole piston rod.

[0012] Further explanation includes a scraping assembly, which includes rodless cylinders fixed to both sides of the guide frame. A fixed block is fixed to the moving part of the rodless cylinder, and a U-shaped scraper is rotatably connected between the corresponding fixed blocks to scrape off the waste material attached to the bottom of the guide frame. A torsion spring is connected between the U-shaped scraper and the rotating part of the fixed block. A limit component is provided inside the guide frame to drive the U-shaped scraper to swing and contact the bottom of the guide tube.

[0013] Further explanation: The limiting component includes magnetic rods fixed to both sides inside the guide frame. A sleeve is slidably fitted on the magnetic rod. The sleeve is made of iron. A limiting frame is fixed to the outside of the sleeve. The limiting frame is located on the right side of the U-shaped scraper to drive the U-shaped scraper to swing downward. A contact rod is fixed to the top of the sleeve. The contact rod contacts the bottom of the movable block.

[0014] Further explanation includes a movable frame that is slidably connected within the guide frame, with a filter screen fixed inside the movable frame to filter and remove waste materials from the waste liquid.

[0015] The significant advancement of this invention lies in:

[0016] 1. Place the board on the support frame, then start the laser cutting head and move it forward to the cutting position. At the same time, the trigger plate drives the single-hole piston rod to move upward through the roller. The water in the water inlet pipe is discharged into the guide pipe. The water in the guide pipe is slowly sprayed out through the nozzle and flows on the support frame to form a water flow layer. When the laser cutting head cuts the board, the waste material falls off and is removed by the water flow layer to prevent the waste material from adhering to the support frame and clumping up, which will scratch the board material placed later, thus ensuring the integrity and quality of the board material.

[0017] 2. Under the action of the U-shaped scraper, whenever the rodless cylinder is started, it drives the fixed block to move to the right. The U-shaped scraper moves to the right and swings downward through the limit frame to contact the bottom of the guide frame. The U-shaped scraper continues to move to the right to remove the waste material attached to the bottom of the guide frame. This can prevent the waste material from adhering to the bottom of the guide frame and forming clumps, which will block the subsequent waste material and make it difficult to discharge and collect. This ensures that the waste material is discharged and collected smoothly.

[0018] 3. With the help of the filter screen, whenever the waste liquid falls into the guide frame, the filter screen can filter the waste material in the waste liquid. The waste liquid after filtering the waste material is discharged through the guide frame, which can prevent a large amount of waste material from being mixed in the waste liquid and affecting subsequent reuse, thus facilitating the subsequent use of the waste liquid.

[0028] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0029] Example: A laser cutting machine capable of automatically cleaning waste materials; please refer to [link / reference]. Figures 1-5 As shown, the device includes a U-shaped plate 1 and a base frame 2 symmetrically fixed to the outside of the U-shaped plate 1. A guide frame 3 is fixed to the outside of the U-shaped plate 1, which can collect waste materials and waste liquid. The bottom of the guide frame 3 is inclined, and the inclined surface of the guide frame 3 slopes downward from left to right. A laser cutting head 6 is installed on the upper part of the U-shaped plate 1. Movable blocks 4 are fixed to both sides of the laser cutting head 6. A support frame 8 is installed on the inner side of the U-shaped plate 1, which can support and place the plate. The device also includes a guide pipe 9, a water inlet pipe 10, a spray pipe 101, and a connecting component. The guide pipe 9 is evenly spaced... The partition is fixedly connected to the support frame 8. Seven spray pipes 101 are evenly spaced laterally on the guide pipe 9. The spray pipes 101 pass through the support frame 8. A water inlet pipe 10 is fixedly connected to the lower part of the right side of the inner side of the U-shaped plate 1. The water inlet pipe 10 is connected to the right end of the guide pipe 9. The connecting component is installed between the movable block 4 and the guide pipe 9. The connecting component is used to control the water in the water inlet pipe 10 to flow into the guide pipe 9. Then the water in the guide pipe 9 flows into the spray pipes 101. The spray pipes 101 spray water onto the support frame 8 so that the water flows on the support frame 8 to remove the fallen waste.

[0030] Please see Figure 4 and Figure 5As shown, the connecting component includes a trigger plate 11, a single-hole piston rod 111, a connecting spring 112, and a roller 113. The single-hole piston rod 111 is slidably connected to the right side of the guide tube 9. The hole of the single-hole piston rod 111 is set horizontally. The connecting spring 112 is connected between the lower part of the single-hole piston rod 111 and the bottom right side of the guide tube 9. The roller 113 is rotatably connected to the bottom end of the single-hole piston rod 111. The trigger plate 11 is fixed to the left end of the right movable block 4. The front and rear sides of the trigger plate 11 are inclined surfaces, and the inclined surfaces of the trigger plate 11 are inclined towards the guide tube 9 and close to its own center position. When the trigger plate 11 moves and contacts the roller 113, the trigger plate 11 can drive the single-hole piston rod 111 to move upward.

[0031] First, connect the water inlet pipe 10 to an external water source and slowly drain water into it. The water in the inlet pipe 10 flows into the guide pipe 9 and is blocked by the single-hole piston rod 111. Then, start the laser cutting head 6 and move it up and down to the appropriate height for laser cutting the sheet material. Next, place the sheet material on the support frame 8 and start the laser cutting head 6 to move forward to the cutting position. The laser cutting head 6 drives the trigger plate 11 to move forward through the movable block 4. The laser cutting head 6 and the trigger plate 11 move synchronously. The trigger plate 11 moves forward and contacts the roller 113. The trigger plate 11 is driven by the roller 113. The single-hole piston rod 111 moves upward, compressing the connecting spring 112. The upward movement of the single-hole piston rod 111 connects with the guide pipe 9, thus stopping the water flow in the inlet pipe 10. The water in the inlet pipe 10 flows into the guide pipe 9, and then into the spray nozzle 101. The water in the spray nozzle 101 slowly sprays out and flows on the support frame 8, forming a water flow layer. When the laser cutting head 6 moves forward to the cutting position, it can be activated to laser cut the sheet metal. Some of the waste generated during the laser cutting process will fall downwards. The support frame 8 contacts the water flow layer. The flowing water removes waste material to prevent it from adhering to the support frame 8 and clumping, which could scratch the subsequently placed boards, thus ensuring the integrity of the boards. The removed waste material mixes with the water to form waste liquid, which falls into the guide frame 3. The guide frame 3 discharges the waste liquid for collection and treatment. This process is repeated. After each part of the board is laser-cut, the laser cutting head 6 is restarted and moves forward to the next cutting position on the board for laser cutting. Meanwhile, the trigger plate 11 continues to move forward and disengages from the rear roller 113, due to the connection spring 112. The function is that the single-hole piston rod 111 moves downward to reset, blocking the water in the inlet pipe 10, stopping the water from flowing into the guide pipe 9. The nozzle 101 corresponding to the cut position of the plate stops spraying water, and the next nozzle 101 corresponding to the cut position sprays water. In this way, the water spray position is synchronized with the position of the laser cutting head 6. After the plate is laser cut, the laser cutting head 6 is turned off to stop cutting. The laser cutting head 6 is started to move and drive the movable block 4 to move backward to reset. The movable block 4 triggers the plate 11 to move backward to reset, and then the cut plate is removed from the support frame 8.

[0032] Please see Figure 6 and Figure 7As shown, it also includes a scraping assembly installed on the guide frame 3. The scraping assembly includes a rodless cylinder 13, a fixing block 131, a U-shaped scraper 132, a torsion spring 133, and a limiting assembly. Rodless cylinders 13 are installed on both the front and rear sides of the guide frame 3. Fixing blocks 131 are fixed to the moving parts of the rodless cylinders 13 on both sides. A U-shaped scraper 132 is rotatably connected between the fixing blocks 131 on both sides. When the U-shaped scraper 132 moves and contacts the bottom of the guide frame 3, it can scrape away the waste material attached to the bottom of the guide frame 3. A torsion spring 133 connects the rotating part of the U-shaped scraper 132 and the fixing block 131. A limiting assembly is provided inside the guide frame 3. When the limiting assembly is activated... When the positioning component is in operation, the limiting component can drive the U-shaped scraper 132 to swing and contact the bottom of the guide tube 9. The limiting component includes a magnetic rod 134, a sleeve 135, a contact rod 136 and a limiting frame 137. Magnetic rods 134 are fixedly connected to the lower part of the front and rear sides of the guide frame 3. The sleeves 135 are slidably fitted on the magnetic rods 134 on the front and rear sides. The sleeves 135 are made of iron. The limiting frame 137 is fixedly connected to the outside of the sleeves 135 on the front and rear sides. The limiting frame 137 is located on the right side of the U-shaped scraper 132. The limiting frame 137 can drive the U-shaped scraper 132 to swing downward. The contact rods 136 are fixedly connected to the top of the sleeves 135 on the front and rear sides. The upper part of the contact rods 136 contacts the bottom right side of the movable block 4.

[0033] After all the sheet metal has been laser-cut, the rodless cylinder 13 is activated, causing the fixed block 131 to move to the right and disengage from the contact rod 136. The movement of the fixed block 131 to the right moves the U-shaped scraper 132 to the right, bringing it into contact with the limiting frame 137. Because the sleeve 135 is in magnetic contact with the magnetic rod 134, the magnetic force is greater than the elastic force of the torsion spring 133, causing the limiting frame 137 to swing the U-shaped scraper 132 downwards. The torsion spring 133 is compressed, and the U-shaped scraper 132 swings downwards to contact the bottom of the guide frame 3. The U-shaped scraper 132 stops swinging downwards and continues to move to the right, moving the limiting frame 137 to the right. The limiting frame 137 then moves the sleeve 135 to the right, causing the sleeve 135 to slide on the magnetic rod 134. When the sleeve 135 moves the contact rod 136 to the right, the U-shaped scraper 132 moves to the right to remove the waste material attached to the bottom of the guide frame 3. The removed waste material is discharged and collected through the guide frame 3. When the U-shaped scraper 132 moves to the right to its maximum stroke, the rodless cylinder 13 is activated to move the fixing block 131 to the left to reset. The fixing block 131 moves to the left, causing the U-shaped scraper 132 to move to the left and disengage from the limit frame 137. Due to the action of the torsion spring 133, the U-shaped scraper 132 swings upward and disengages from the bottom of the guide frame 3. When the fixing block 131 moves to the left and contacts the contact rod 136, the fixing block 131 moves the contact rod 136 to the left to reset. The contact rod 136, through the sleeve 135, moves the limit frame 137 to the left to reset. In this way, it is possible to prevent waste material from adhering to the bottom of the guide frame 3 and caking, which would block subsequent waste material and make it difficult to discharge and collect, thus ensuring smooth discharge and collection of waste material.

[0034] Please see Figure 8 As shown, it also includes a movable frame 14 and a filter screen 15. The movable frame 14 is slidably connected to the lower right side of the guide frame 3, and the filter screen 15 is fixed to the lower inner side of the movable frame 14. When the waste liquid comes into contact with the filter screen 15, the filter screen 15 can filter and remove the waste material in the waste liquid.

[0035] When the waste liquid falls into the guide frame 3, it comes into contact with the filter screen 15. The filter screen 15 filters out the waste material in the waste liquid, and the filtered waste liquid is discharged through the guide frame 3. After all the waste liquid has been discharged, the movable frame 14 is pulled forward to disengage from the guide frame 3, and the waste material on the filter screen 15 is poured out. Then, the movable frame 14 is placed back into the guide frame 3. This prevents a large amount of waste material from being mixed into the waste liquid, which would affect subsequent reuse, thus facilitating the subsequent use of the waste liquid.
