Description

Technical Field

[0001] This utility model relates to the field of smoke extraction technology for cutting machines, and in particular to a follow-up smoke extraction device for laser cutting machines. Background Technology

[0002] The laser cutting machine follow-up fume extraction device is a fume purification system specifically designed for the laser cutting process. It dynamically follows the movement of the cutting head, captures and discharges the fumes and exhaust gases generated in the cutting area in real time, thereby maintaining a clean working environment, protecting the health of operators, and improving cutting quality.

The control panel is located on the outer frame, the guide rod is located on the upper part of the outer frame, the pneumatic sliding device slides on the guide rod, the toothed rod is connected to the pneumatic sliding device, the lifting light-shielding device is located on the outer ring of the toothed rod, the cutting head is located at the lower end of the toothed rod, the carrier plate is located at the lower part of the outer frame, the carrier plate is provided with pointed steel parts, a drainage groove is provided between the carrier plate and the outer frame, and the water circulation device is located inside the cutting head. This utility model belongs to the field of cutting machine technology, specifically referring to a follow-up smoke exhaust device for a laser cutting machine that can effectively reduce the emission of smoke and dust, and at the same time block the arc light during the cutting process.

[0004] In existing technologies, during laser cutting, a protective cover is used to further block the smoke, and water mist is sprayed onto the cutting area through a water nozzle to absorb some of the smoke. An air pump is used to absorb the remaining smoke, thus achieving smoke exhaust. However, the thickness of the cut materials varies. If the material is thick, the cutting speed slows down, resulting in more smoke. Because there is a large gap between the protective cover and the material, some of the smoke will disperse through the gap and is difficult to collect and treat effectively, thus affecting the smoke exhaust effect and the workshop working environment. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the thickness of the cut plates varies. When the plate is thick, the cutting speed slows down, resulting in more smoke. Because there is a large gap between the protective cover and the plate, some of the smoke will disperse through the gap and is difficult to collect and treat effectively, thus affecting the smoke exhaust effect and the workshop working environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laser cutting machine follow-up smoke exhaust device, including a worktable, a cutting structure is provided at the top of the worktable, the cutting structure includes a cutting component and a smoke exhaust component, a placement groove is provided in the middle of the top of the worktable, first sliding grooves are provided on both sides of the worktable inside the placement groove, a collection box is fixedly connected to both ends of the worktable, a clamping component is fixedly provided at the bottom of the worktable at the first sliding groove, and a cleaning component is provided inside the worktable at the placement groove.

[0007] In a preferred embodiment, the cleaning assembly includes a second motor, which is fixed to one side of one end of the worktable. A second lead screw is driven to one side of the second motor, and the second lead screw rotates through the worktable. The second lead screw is located inside a first slide groove on one side, and a second slider is threaded to the middle of the second lead screw. The second slider is slidably connected inside the first slide groove.

[0008] In a preferred embodiment, a connecting frame is fixedly connected to one side of the second slider that is close to each other. A pull rod is slidably connected to the middle of the connecting frame. The pull rod passes through the connecting frame. A pull ring is fixedly connected to the top of the pull rod. A connecting plate is fixedly connected to the bottom of the pull rod. A cleaning plate is fixedly connected to the bottom of the connecting plate. The cleaning plate is slidably connected to the worktable and the clamping parts.

[0009] In a preferred embodiment, springs are fixedly connected at equal intervals on both sides of the top of the connecting plate, the springs are fixedly connected to the connecting frame, and limit grooves are formed on both sides of the bottom end of the connecting frame, the limit grooves are slidably connected to the connecting plate.

[0010] In a preferred embodiment, the cutting assembly includes a bracket fixed to the top of the workbench. A second groove is formed in the middle of the top of the bracket, and a first slider is slidably connected inside the second groove. A first lead screw is threadedly connected to the middle of the first slider. One end of the first lead screw rotatably passes through the bracket, and a first motor is drivenly connected to the end of the first lead screw passing through it. The first motor is fixedly mounted to the bracket. A cylinder is fixedly mounted at the top of the first slider, and the output end of the cylinder slidably passes through the first slider. A cutting head is fixedly connected to the output end of the cylinder, and a protective cover is fixedly connected to the top of the cutting head.

[0011] In a preferred embodiment, the smoke exhaust assembly includes a collection box, which is located in the middle of one side of the workbench. An air pump is fixedly connected to one side of the top of the collection box, and a discharge pipe is fixedly connected to one side of the air pump. The discharge pipe is fixedly connected to the collection box, and a collection pipe is fixedly connected to the other side of the air pump. The collection pipe passes through the support, and two ports are provided at the end of the collection pipe away from the air pump. One port of the collection pipe is fixedly connected to a fixed through-protective cover.

[0012] In a preferred embodiment, another port of the collection tube is fixedly connected to an annular tube, which surrounds the outside of the protective cover. The bottom end of the annular tube is fixedly connected to a suction hood, which is fixedly connected to the protective cover. The suction hood has a feeding chamber in the middle and brushes on both sides of the bottom end of the suction hood.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, starting the air pump causes the collection pipe to generate suction. When the cutting head cuts, it generates smoke, which is absorbed by the collection pipe inside the protective cover. When cutting thicker plates, some smoke is discharged through the gap at the bottom of the protective cover. The suction generated by the collection pipe causes the annular pipe to also generate suction. The annular pipe absorbs the smoke inside the suction hood, and the smoke passing through the bottom of the protective cover is absorbed again when it passes through the bottom of the suction hood, thus preventing the smoke from spreading. When the cutting head moves, it will drive the suction hood to move, and the suction hood will drive the brush to move. The brush sweeps the debris after the plate is cut, and the swept debris is absorbed by the collection pipe, thus initially cleaning the cutting debris and reducing the impact of the debris on the cutting head.

[0015] Before cutting, pull the ring upwards to move the pull rod upwards. The pull rod moves the connecting plate upwards along the track of the limiting groove. The connecting plate lifts the cleaning plate, allowing the sheet material to pass through the bottom of the cleaning plate and be pushed to the bottom of the bracket for cutting. After cutting, start the second motor to move the second slider. The second slider moves the connecting frame, which in turn moves the pull rod and the connecting plate. The connecting plate then moves the cleaning plate, which cleans the debris from the sheet material. The debris is pushed into the collection box for collection, eliminating the need for manual cleaning and improving work efficiency. The cleaning plate is equipped with springs to handle sheets of different thicknesses. After cleaning, the sheet material can be removed, and the second motor can then be used to clean the surface of the placement groove, improving the cleanliness of the top of the workbench.

After cleaning, the plate can be taken out, and the second motor 31 drives the cleaning plate 38 to clean the surface of the placement groove 12, improving the cleanliness of the top of the workbench 1.

[0028] like Figure 1 - Figure 4 As shown, the cutting assembly includes a bracket 21, which is fixed to the top of the workbench 1. A second groove 211 is provided in the middle of the top of the bracket 21. A first slider 212 is slidably connected inside the second groove 211. A first lead screw 213 is threadedly connected to the middle of the first slider 212. One end of the first lead screw 213 rotates through the bracket 21. A first motor 214 is drivenly connected to the through end of the first lead screw 213. The first motor 214 is fixedly set to the bracket 21. A cylinder 215 is fixedly set at the top of the first slider 212. The output end of the cylinder 215 slides through the first slider 212. A cutting head 216 is fixedly connected to the output end of the cylinder 215. A protective cover 217 is fixedly connected to the top of the cutting head 216. The smoke exhaust assembly includes a collection box 22, which is set in the workbench 1. On one side of the middle of platform 1, an air pump 221 is fixedly connected to one side of the top of the collection box 22. A discharge pipe 222 is fixedly connected to one side of the air pump 221 and the collection box 22 is fixedly connected. A collection pipe 223 is fixedly connected to the other side of the air pump 221 and the collection pipe 223 is fixedly connected through the bracket 21. Two ports are provided at the end of the collection pipe 223 away from the air pump 221. One port of the collection pipe 223 is fixedly connected to the protective cover 217 and the other port of the collection pipe 223 is fixedly connected to the annular pipe 224. The annular pipe 224 surrounds the outside of the protective cover 217 and a suction hood 225 is fixedly connected to the bottom end of the annular pipe 224. The suction hood 225 is fixedly connected to the protective cover 217. A feeding chamber 227 is opened in the middle of the suction hood 225 and brushes 226 are opened on both sides of the bottom end of the suction hood 225.

[0029] In this embodiment, the starting cylinder 215 drives the cutting head 216 and the protective cover 217 to move downwards. The cutting head 216 cuts the plate. The starting motor 214 drives the first lead screw 213 to rotate. The first lead screw 213 can drive the cutting head 216 and the protective cover 217 to move, thereby realizing the cutting. During cutting, the air pump 221 is started to generate suction in the collection pipe 223. The cutting head 216 generates smoke when cutting. The smoke is absorbed by the collection pipe 223 inside the protective cover 217. When cutting thicker plates, some of the smoke is discharged through the gap at the bottom of the protective cover 217. The suction generated by the collection pipe 223 causes the annular pipe 224 to also generate suction. The annular pipe 224 absorbs the smoke inside the suction hood 225, and the smoke passing through the bottom of the protective cover 217 is absorbed again when it passes through the bottom of the suction hood 225, thus preventing the smoke from dispersing. When the cutting head 216 moves, it will drive the suction hood 225 to move. The suction hood 225 drives the brush 226 to move. The brush 226 sweeps the debris after the board is cut. The swept debris is absorbed by the collection pipe 223, thus initially cleaning the cutting debris and reducing the impact of the debris on the cutting head 216.

[0030] Working principle: First, during use, pulling the pull ring 36 upwards moves the pull rod 35 upwards. The pull rod 35 moves the connecting plate 37 upwards along the trajectory of the limiting groove 341. The connecting plate 37 lifts the cleaning plate 38, allowing the plate to pass through the bottom of the cleaning plate 38 and be pushed to the bottom of the bracket 21. The plate is then clamped by the clamping member 14. Because the clamping member 14 has an internal spring, it can accommodate plates of different widths. Then, the cylinder 215 is activated, causing the cutting head 216 and the protective cover 217 to move downwards. 216 cuts the sheet metal. The first motor 214 is started, driving the first lead screw 213 to rotate. The lead screw 213 can move the cutting head 216 and the protective cover 217, thus achieving cutting. During cutting, the air pump 221 is activated, causing the collection pipe 223 to generate suction. The cutting head 216 generates smoke during cutting, which is absorbed by the collection pipe 223 inside the protective cover 217. When cutting thicker sheets, some smoke is discharged through the gap at the bottom of the protective cover 217. The suction generated by the collection pipe 223 also causes the annular pipe 224 to generate suction. The smoke is absorbed inside the suction hood 225, and the smoke passing through the bottom of the protective cover 217 is absorbed again when it passes through the bottom of the suction hood 225, thus preventing the smoke from dispersing. When the cutting head 216 moves, it will drive the suction hood 225 to move. The suction hood 225 drives the brush 226 to move. The brush 226 sweeps the debris after the plate is cut. The swept debris is absorbed by the collection pipe 223, thus initially cleaning the cutting debris and reducing the impact of the debris on the cutting head 216. After the cutting is completed, the second motor 31 is started to drive the second slider 33 to move. The second slider 33 drives the connecting frame 34 to move, the connecting frame 34 drives the pull rod 35 and the connecting plate 37 to move, the connecting plate 37 drives the cleaning plate 38 to move, the cleaning plate 38 cleans the debris on the board, and the debris is pushed into the collection box 11 for collection, so no personnel are needed to clean it, thus improving work efficiency. The cleaning plate 38 is equipped with a spring 39 to clean boards of different thicknesses. After cleaning, the board can be taken out, and the second motor 31 drives the cleaning plate 38 to clean the surface of the placement groove 12, improving the cleanliness of the top of the workbench 1.
