Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal sheet processing technology, and in particular to a scrap cleaning device for steel plate cutting. Background Technology
[0002] Metal laser cutting machines are laser cutting equipment specifically used for cutting and processing metal materials such as steel plates. When cutting steel plates, the steel plates are placed on the support table of the laser cutting machine. The table surface is usually composed of support bars with multiple serrations arranged and fixed on the upper part of the support platform. The serrations of the support bars face upwards, and there is a gap between adjacent support bars.
[0003] After the metal sheet laser cutting machine has cut the steel sheet, the cut products need to be picked out and put into the product collection box. The remaining scraps need to be cleaned off from the support table. Usually, this is done manually by wearing gloves to pick up the scraps from the support table of the laser cutting machine and put them into the waste collection box. Cleaning up the waste increases the workload of the workers, and manual cleaning is relatively inefficient. Utility Model Content
[0004] The purpose of this invention is to provide a scrap cleaning device for steel plate cutting, which has the advantage of facilitating the cleaning of scraps cut by metal laser cutting machines.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A scrap cleaning device for steel plate cutting includes a cutting device with a support stand. A lifting mechanism is located on one side of the support stand, connected to a support plate. A moving mechanism is located on the upper part of the support plate, connected to an mounting plate. The moving mechanism drives the mounting plate to move along the length of the support stand. The mounting plate is slidably connected to the support plate. The mounting plate has a pushing mechanism, slidably connected to a connecting plate. The connecting plate is connected to the pushing mechanism, which drives the connecting plate to move along the width of the support stand. A push plate is fixedly connected to the connecting plate, and brush bristles are fixedly connected to the bottom surface of the push plate. A discharge chamber is located at one end of the support stand, with openings at both the upper and lower ends, the openings being wider at the top and narrower at the bottom. A collection box is placed below the lower opening of the discharge chamber.
[0006] Using the above technical solution, after the cutting equipment cuts the metal sheet, the worker picks out the desired finished product and removes it. The pushing mechanism then moves the connecting plate relative to the mounting plate along the width of the cutting equipment. The connecting plate moves the push plate, bringing it directly above the support stand of the cutting equipment and aligning it with the support stand. The lifting mechanism lowers the support plate, which in turn lowers the mounting plate, the pushing mechanism, the connecting plate, and the push plate. The push plate descends until its bottom bristles penetrate between two adjacent support bars on the support stand, and the bottom surface of the push plate contacts the upper surface of the support bars. The moving mechanism then moves the mounting plate along the length of the cutting equipment, which in turn moves the connecting plate and the push plate. The push plate pushes the scrap material on the upper part of the support stand towards the end of the support stand that is fixedly connected to the discharge chamber. The push plate pushes the scrap material into the discharge chamber, where it falls into the collection box. This reduces the workload of the workers and is much more efficient than manually picking up each scrap material and placing it into the collection box.
[0007] Preferably, the moving mechanism is a lead screw, which is horizontally rotatably connected to the upper part of the support plate. The axis of the lead screw is parallel to the length direction of the cutting equipment, and the mounting plate is fixedly connected to the slider of the lead screw.
[0008] Using the above technical solution, when the lead screw rotates, its slider drives the mounting plate and the pushing mechanism, connecting plate and push plate on the upper part of the mounting plate to move along the length of the support table.
[0009] Preferably, the bottom of the push plate is integrally formed with a slope, the slope surface is higher closer to the push plate, and a horizontal baffle is fixedly connected to the upper part of the push plate.
[0010] Using the above technical solution, the push plate moves, and the ramp of the push plate pushes the steel plate scraps to move. The ramp facilitates the movement of the scraps. The push plate blocks the scraps, preventing the ramp of the push plate from exerting an upward force on the scraps, causing the scraps to move upward and over the push plate, thus affecting the scraps being pushed into the collection box.
[0011] Preferably, the pushing mechanism is a cylinder, a side plate is fixedly connected to one end of the mounting plate, the cylinder is horizontally fixedly connected to the side of the side plate, and the cylinder output shaft is fixedly connected to the connecting plate.
[0012] Using the above technical solution, the cylinder output shaft extends or retracts to push the connecting plate to move relative to the mounting plate along the width direction of the support table. The connecting plate drives the push plate to move directly above the support table or move away from directly above it.
[0013] Preferably, the push plate is fixedly connected to a horizontal guide rod, which passes through the side and is slidably connected to the side.
[0014] Using the above technical solution, the pushing mechanism pushes the connecting plate to move relative to the mounting plate, the connecting plate drives the guide rod to move relative to the side, the side plate limits the movement of the guide rod, increasing the stability of the push plate moving along the width of the support table, and at the same time the side plate provides support to the push plate through the guide rod, increasing the stability of the push plate's movement.
[0015] Preferably, limiting plates are fixedly connected to both sides of the push plate, and the opposite surfaces of the two limiting plates are provided with inclined surfaces, which are closer to the middle of the push plate.
[0016] Using the above technical solution, during the process of the push plate moving the scrap material, the limiting plates on both sides of the push plate block the scrap material to prevent it from going out from both sides of the push plate. At the same time, the inclined surface of the limiting plate pushes the scrap material to move towards the middle of the push plate. Attached Figure Description

[0020] See Figure 1 , Figure 5 , Figure 6 and Figure 8 A scrap cleaning device for steel plate cutting includes a cutting device, the cutting device is provided with a support plate 1, and the support surface is fixedly connected with multiple serrated support strips arranged in an arrangement, the serrations of the support strips facing upwards, and there is a gap between two adjacent support strips. A lifting mechanism is provided on one side of the support plate 1. The lifting mechanism is connected to the support plate 2. The lifting mechanism is a scissor lift. The scissor lift includes a base plate 15, a scissor frame 16, and a driving component. Slide plates 17 are slidably connected to the upper surface of the base plate 15 and the lower surface of the support plate 2, respectively. The scissor frame 16 is located above the base plate 15. One end of the clamping frame has two feet that are hinged to the base plate 15 and the slide plate 17 on the base plate 15, respectively. The support plate 2 is located above the scissor frame 16. The other end of the scissor frame 16 has two feet that are hinged to the support plate 2 and the slide plate 17 at the bottom of the support plate 2, respectively. The driving component is connected to the base plate 15. The driving component can be a hydraulic cylinder and a second lead screw 18. The hydraulic cylinder is hinged to the base plate 15, and the output shaft of the hydraulic cylinder is hinged to the bracket of the scissor frame 16. When the driving component is the second lead screw 18, the second lead screw 18 is horizontally rotatably connected to the upper surface of the base plate 15, and the slide plate 17 is fixedly connected to the slider of the second lead screw 18.
[0021] See Figure 2 , Figure 4 , Figure 6 and Figure 7 A horizontal lead screw 9 is rotatably connected to the upper part of the support plate 2. The axis of the lead screw 9 is parallel to the length direction of the cutting equipment. The slider of the lead screw 9 is fixedly connected to the mounting plate 3. A pair of guide rails parallel to the length direction of the cutting equipment are fixedly connected to the upper part of the support plate 2. The bottom of the mounting plate 3 has two slots that match the two guide rails. The two slots at the bottom of the mounting plate 3 are respectively embedded in the two guide rails. The mounting plate 3 and the guide rails of the support plate 2 are slidably connected. A side plate is welded to one end of the mounting plate 3. A horizontal cylinder 12 is fixedly connected to the side of the side plate. A connecting plate 4 is provided on the upper part of the mounting plate 3. A connecting block with a trapezoidal cross-section is integrally formed on the upper surface of the mounting plate 3. The connecting block is wider at the top and narrower at the bottom. The connecting plate 4 has a trapezoidal slot that matches the trapezoidal connecting block. The trapezoidal slot of the connecting plate 4 is embedded in the trapezoidal connecting block. The connecting plate 4 and the connecting block of the mounting plate 3 are slidably connected. The connecting plate 4 is fixedly connected to the output shaft of the cylinder 12. The cylinder 12 drives the connecting plate 4 to move along the width direction of the support plate 1.
[0022] See 1. Figure 3 , Figure 7 and Figure 8A push plate 5 is fixedly connected to the connecting plate 4, and a horizontal guide rod 13 is fixedly connected to the push plate 5. The guide rod 13 passes through the side and is slidably connected to the side. Limiting plates 14 are integrally formed on both sides of the push plate 5. The opposing surfaces of the two limiting plates 14 are provided with inclined surfaces. The inclined surfaces are closer to the middle of the push plate 5. A horizontal baffle 11 is integrally formed on the upper part of the push plate 5. A ramp 10 is integrally formed on the bottom of the push plate 5. The surface of the ramp 10 is higher closer to the push plate 5. The ramp 10 can pick up the scrap steel plate, thereby better pushing the scrap material to move. At the same time, the push plate 5 blocks the scrap material, preventing the ramp 10 of the push plate 5 from exerting an upward force on the scrap material, causing the scrap material to move upward over the push plate 5, which would affect the pushing of the scrap material into the collection box 8. The bottom surface of the push plate 5 is fixedly connected with bristles 6, and a feeding chamber 7 is provided at one end of the support table 1. The feeding chamber 7 has openings at both the upper and lower ends, and the openings at the upper and lower ends of the feeding chamber 7 are wider at the top and narrower at the bottom. A collection box 8 is placed below the opening at the lower end of the feeding hopper.
[0023] Working Principle: After the cutting equipment cuts the metal sheet, the worker picks out the desired finished product and removes it. The output shaft of cylinder 12 extends and pushes the connecting plate 4 relative to the mounting plate 3 along the width of the support table of the cutting equipment. The connecting plate 4 drives the push plate 5 to move, so that the push plate 5 is directly above the support table 1 of the cutting equipment and aligned with the support table 1 horizontally. The lead screw 18 rotates, and its slider drives the slide plate 17 to move. The slide plate 17 drives the two legs of the scissor frame 16 to move away from each other, and the scissor frame 16 retracts, thereby driving the support plate 2 to descend. The support plate 2 drives the mounting plate 3 and the cylinder 12, connecting plate 4 and push plate 5 on the upper part of the mounting plate 3 to descend. The push plate 5 descends until the bristles 6 on its bottom surface penetrate between two adjacent support bars on the support table 1, and the bottom surface of the push plate 5 contacts the upper surface of the support bar.
[0024] When the lead screw 9 rotates, its slider drives the mounting plate 3 to move along the length of the cutting equipment. The mounting plate 3 drives the connecting plate 4 and the push plate 5 to move. The push plate 5 pushes the scrap material on the upper part of the support plate 1 towards the end of the support plate 1 that is fixedly connected to the feeding chamber 7. During the process of the push plate 5 pushing the scrap material, the limiting plates 14 on both sides block the scrap material to prevent it from going out from both sides of the push plate 5. At the same time, the inclined surface of the limiting plate 14 pushes the scrap material towards the middle of the push plate 5. The push plate 5 pushes the scrap material into the feeding chamber 7, and the scrap material falls into the collection box 8 through the feeding chamber 7. Then, lead screw 18 rotates in the reverse direction, and the lead screw slider moves, causing the two legs of the scissor frame 16 to move closer together via slide plate 17, thus extending the scissor frame 16. The scissor frame 16 drives the support plate 2 to rise, and the support plate 2 drives the mounting plate 3 and the cylinder 12, connecting plate 4, and push plate 5 on the upper part of the mounting plate 3 to rise. The bristles 6 at the bottom of the push plate 5 move away from the gap between two adjacent support bars on the support table 1. The output shaft of cylinder 12 retracts, driving the connecting plate 4 and push plate 5 away from above the tabletop of the support table 1, and the connecting plate 4 and push plate 5 return to their original positions. This reduces the workload of workers and is much more efficient than manually picking up scraps one by one and putting them into the collection box 8.
