Description

Technical Field

[0001] The invention relates to the technical field of mold processing, and in particular to a laser cutting device for mold processing. Background Art

[0002] When processing molds, a laser cutting device is required. Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material.

[0003] The patent with publication number CN114289902A provides a laser cutting device for mold processing, including a cutting machine body, on which a cutting head body is installed; a dust removal mechanism is fixed on the cutting machine body; a guide mechanism is connected to the cutting machine body; a sliding mechanism is installed on the cutting machine body; the sliding mechanism is connected to a collection box; a lubrication mechanism is connected to the sliding mechanism; a moving mechanism is installed on the cutting machine body; turn on the control switch of the dust removal mechanism, so that the debris and smoke generated during cutting can be sucked into the interior for collection; the operator manually adjusts the spacing of the sliding mechanism according to the size of the mold after cutting, so that the mold after cutting can fall onto the sliding mechanism, which makes it convenient for the operator to check the mold while preventing the operator from being burned by the working device when directly taking the cut mold with hands.

[0004] However, in actual use, the waste residue generated by laser cutting will fall onto the workbench. If the waste residue is not cleaned up in time, it will stick to the workbench after cooling, making it difficult to clean. In addition, it is difficult to fix the mold plate, affecting the cutting efficiency.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the invention

[0006] The object of the present invention is to provide a laser cutting device for mold processing which can effectively solve the above-mentioned technical problems.

[0007] In order to achieve the purpose of the present invention, the following technical scheme is adopted: a laser cutting device for mold processing, comprising: a laser cutting component, a conveyor belt, a workbench, an exhaust component installed in the workbench, and a cleaning component installed under the conveyor belt, the exhaust component comprising: an exhaust fan, an exhaust pipe, and a nozzle, a filter is installed on the exhaust pipe, the cleaning component is composed of a detachable scraper and a cleaning structure, and the motor that controls the operation of the conveyor belt drives the cleaning structure to operate through a belt assembly.

[0008] Furthermore, an adjustable guide plate is installed on the conveyor belt.

[0009] Furthermore, an inspection door is installed on the side of the workbench.

[0010] Furthermore, a pull-out ash box is installed at the lower left of the filter screen.

[0011] Furthermore, the cleaning structure includes: a fixed frame, a pin mounted on the fixed frame and movable up and down, a pin fixedly mounted below the pin, a limit spring sleeved on the pin, a rotatable shaft mounted below the pin, a cam mounted on the shaft, a vertical plate mounted on the side of the cam, a movable brush mounted on the vertical plate, and a telescopic spring sleeved on the brush.

[0012] Furthermore, the conveyor belt is a chain plate structure.

[0013] Furthermore, the conveyor belt is provided with a plurality of through holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: a laser cutting device for mold processing of the present invention can scrape off the waste slag remaining on the conveyor belt through a scraper, and the exhaust fan sucks the workbench to keep the workbench in a negative pressure state. On the one hand, a pressure difference is generated above and below the mold plate to fix it for welding. At the same time, gas is blown out through the nozzle to blow away the welding slag generated by cutting for cutting. On the other hand, the waste slag scraped off by the scraper can be concentrated on the filter net to prevent the waste slag from floating everywhere and avoid the environment.

[0023] like Figures 1 to 4 As shown, the present invention provides a laser cutting device for mold processing, comprising: a laser cutting component 1, a conveyor belt 2, a workbench 3, an exhaust component installed in the workbench 3, and a cleaning component installed under the conveyor belt 2.

[0024] The laser cutting assembly 1 is installed on the workbench 3. The laser cutting assembly 1 is composed of a laser generator, a beam transmission component, a microcomputer numerical control cabinet, a cooler assembly, a driving component, a computer, etc. The laser cutting assembly 1 can be used to cut the mold plate.

[0025] An adjustable guide plate 4 is installed on the conveyor belt 2, which is used to limit the mold plate during transportation to prevent it from running off track. The guide plate 4 is connected to the adjusting screw. By rotating the adjusting screw, the guide plate 4 is pushed to move and the spacing of the guide plates 4 is adjusted to limit and guide mold plates of different widths.

[0026] A waste box 5 is placed at the lower right side of the conveyor belt 2 for collecting the cut waste. A discharge platform 6 is placed on the side of the waste box 5. A conveying roller 7 is installed on the discharge platform 6. The cut mold plate can be transported to the discharge platform 6 by the conveying roller 7 for cooling so as to discharge the material. A dropping port is opened on the conveying roller 7, and the waste can fall into the waste box 5 through the dropping port.

[0027] The exhaust assembly includes: an exhaust fan 9, an exhaust pipe 10, and a nozzle 14. The nozzle 14 is connected to the laser cutting assembly 1. When the laser cutting assembly 1 moves, the nozzle 14 moves accordingly. The conveyor belt 2 is a chain plate structure, and a plurality of through holes 15 are opened on the conveyor belt 2 for exhaust.

[0028] In the process of laser cutting of mold plates, waste residue will be generated. If the waste residue is not cleaned up in time, it will affect the cutting work. In addition, it is difficult to fix the mold plate, which makes it easy for the mold plate to move during cutting.

[0029] In the present invention, the air in the workbench 3 is extracted by starting the exhaust fan 9, and the gas is blown out through the nozzle 14, which can blow away the waste slag generated during cutting to prevent the waste slag from affecting the cutting work. In addition, the air in the workbench 3 is extracted to generate negative pressure, which can fix the mold plate through the pressure difference between the upper and lower parts, so as to facilitate better cutting.

[0030] When the exhaust fan 9 is running, the waste residue in the workbench 3 is easy to enter the exhaust pipe 10, causing the exhaust pipe 10 to be blocked and resulting in low exhaust efficiency.

[0031] By installing the filter 11 on the exhaust pipe 10, the filter 11 can filter the waste residue to prevent the waste residue from entering the exhaust pipe 10, thereby effectively solving the problem that the exhaust pipe 10 is blocked by the waste residue.

[0032] A pull-out ash box 8 is installed at the lower left of the filter screen 11 for collecting waste residues. An inspection door is installed on the side of the workbench 3. The inspection door is opened, the ash box 8 is pulled out, and the waste residues therein can be cleaned.

[0033] The cleaning assembly is composed of a detachable scraper 13 and a cleaning structure 12. The motor that controls the operation of the conveyor belt 2 drives the cleaning structure 12 to operate through the belt assembly. The cleaning structure 12 includes: a fixed frame 1209, a pin 1208 that can move up and down and is mounted on the fixed frame 1209, a push rod 1206 that is fixedly mounted below the pin 1208, a limit spring 1207 is sleeved on the push rod 1206 to return the push rod 1206 to an initial position, a rotatable shaft 1205 is mounted below the push rod 1206, a cam 1204 is mounted on the shaft 1205, a vertical plate 1203 is mounted on the side of the cam 1204, a brush 1201 that can move left and right is mounted on the vertical plate 1203, and a telescopic spring 1202 sleeved on the brush 1201 to return the brush 1201 to an initial position.

[0034] When laser cutting the mold plate, waste residue generated by the laser cutting will fall onto the workbench 3. If the waste residue is not cleaned up in time, it will adhere to the workbench 3 after cooling, making it difficult to clean.

[0035] In the present invention, on the one hand, the scraper 13 can be used to scrape off the waste residue remaining on the conveyor belt 2 to prevent the waste residue from sticking to the conveyor belt 2 after cooling and affecting the use of the conveyor belt 2. On the other hand, under the operation of the exhaust fan 9, the waste residue in the workbench 3 is concentrated on the filter screen 11. During the rotation of the cam 1204 driven by the rotating shaft 1205, the brush 1201 and the push rod 1206 are pushed to move. The brush 1201 moving left and right can clean the waste residue on the filter screen 11 into the ash box 8, and the push rod 1206 moving up and down drives the ejector pin 1208 to move, so as to clean off the waste residue remaining in the through hole 15 of the conveyor belt 2 to prevent the waste residue from clogging the through hole 15 and affecting the air extraction effect.

[0036] Working principle: Start the motor that controls the operation of the conveyor belt 2, and the conveyor belt 2 transports the mold plate to the cutting area. During transportation, the guide plate 4 limits it to prevent it from running off the track. The laser cutting component 1 can cut the mold plate. During cutting, start the exhaust fan 9 to extract the air in the workbench 3 and blow it out through the nozzle 14 to blow away the waste residue generated during cutting to prevent the waste residue from affecting the cutting work. In addition, the air in the workbench 3 is extracted to generate negative pressure, which can fix the mold plate through the pressure difference between the upper and lower parts, so as to better cut it. After cutting, the mold plate is transported to the unloading table 6 through the conveyor roller 7 for cooling to facilitate unloading. The waste falls into the waste box 5 and is collected for centralized treatment later. The plate 13 can scrape off the waste residue remaining on the conveyor belt 2 to prevent the waste residue from sticking to the conveyor belt 2 after cooling and affecting the use of the conveyor belt 2. When the exhaust fan 9 is in operation, the waste residue in the workbench 3 can be concentrated on the filter screen 11. When the motor of the conveyor belt 2 is controlled to operate, the shaft 1205 drives the cam 1204 to rotate through the belt assembly. During the rotation, on the one hand, the brush 1201 is pushed to move left and right to clean the waste residue on the filter screen 11 and collect it in the ash box 8. The ash box 8 can be pulled out to clean the waste residue. On the other hand, the ejector rod 1206 is pushed up and down, and the ejector pin 1208 can clean off the waste residue remaining in the through hole 15 of the conveyor belt 2 to prevent the waste residue from clogging the through hole 15 and affecting the exhaust effect.
