Description

Technical Field

[0001] This invention belongs to the field of cutting machine technology, specifically relating to laser cutting machines. Background Technology

[0002] Laser cutting uses an invisible laser beam instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout for material savings, smooth cuts, and low processing costs. It will gradually improve upon or replace traditional metal cutting equipment. The mechanical parts of the laser head do not contact the workpiece, thus preventing scratches on the work surface during operation.

[0003] In existing laser cutting machines, materials are transported using a conveyor belt. However, when transporting materials, workers need to press the materials onto the conveyor belt and then release them after the belt has transported one end of the material. This is inconvenient for the initial loading. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a laser cutting machine that can be easily loaded with materials.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a laser cutting machine, including a machine base, on which two cutting working areas are arranged side by side. A cutting table is installed on the cutting working area, and a transmission roller is movably arranged above the cutting table. A horizontal driving device for driving the transmission roller to move is provided on the cutting working area. The horizontal driving device includes a guide sliding seat, a lead screw motor, and a transmission lead screw. The guide sliding seat is slidably located above one side of the cutting table, and the lead screw motor is installed above the other side of the cutting table. The transmission lead screw is drivenly connected to the lead screw motor and extends along the moving direction of the guide sliding seat. A guide rail for the guide sliding seat to slide is provided on the cutting working area. A lead screw seat is fitted on the transmission lead screw. A lifting cylinder is installed on both the guide sliding seat and the lead screw seat. The two ends of the transmission roller are rotatably connected to the lifting cylinders on both sides, and one of the lifting cylinders is equipped with a drive motor for driving the transmission roller to rotate.

[0006] The surface of the transfer roller is evenly covered with bristles.

[0007] The lifting cylinder is equipped with a protective cover on the transmission roller. The protective cover has a scraper protruding from the surface facing the transmission roller. The protective cover has dust suction ports on both sides of the scraper. A vacuum cleaner connected to the dust suction ports is installed between the guide sliding seat and the lead screw seat.

[0008] Below the cutting work area is a chip collection and heat dissipation cavity, a heat dissipation fan is installed on one side of the chip collection and heat dissipation cavity, and a chip collection drawer is slidably provided at the bottom of the chip collection and heat dissipation cavity.

[0009] The output of the machine is equipped with a finished product collection machine, which includes a frame and two storage areas that are connected to the two cutting work areas.

[0010] The storage area is equipped with a guide channel, and an isolation plate is rotatably installed in the guide channel. The width of the isolation plate is the same as the width of the guide channel, and the length of the isolation plate is greater than half of the width. An oscillating motor that drives the isolation plate to swing is provided outside the storage area. Two collection baskets are placed below the guide channel.

[0011] The side wall of the collection basket has multiple ventilation holes.

[0012] The storage area is provided with an air guide pipe that connects to the air outlet of the cooling fan. The air guide pipe extends to the top of the frame and is positioned above the storage area. The frame is provided with an air outlet that communicates with the air guide pipe. The outlet of the air outlet faces the storage area. A clamping guide roller is installed on the side of the storage area away from the machine.

[0013] The cooling fan has an extension pipe at its outlet, and the air duct has a telescopic pipe at its inlet that communicates with the extension pipe. The telescopic pipe is fitted with a locking device that is fixedly connected to the extension pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The laser cutting machine of the present invention, when feeding material, places the end of the material at the input of the cutting table and below the transmission roller. Then, the transmission roller is driven to descend by the lifting cylinder to cooperate with the cutting table to clamp and fix the material. Subsequently, the lifting cylinder is driven by the horizontal drive device to drive the transmission roller to move the material on the cutting table. After moving to the designated position, the transmission roller is driven by the drive motor to rotate, which can stably transmit the material without the need for manual pressing, which is convenient for feeding.

[0015] 2. In the laser cutting machine of the present invention, when the brush bristles touch the scraper, the dust on the brush bristles will be scraped off by the scraper, and then sucked away by the vacuum port in conjunction with the vacuum cleaner, so as to realize the ability to transport materials and clean the fabric at the same time, and to clean the brush bristles.

[0016] 3. The laser cutting machine of the present invention guides the material through a guide channel and a partition plate, and guides the material into a collection basket. When the collection basket is full, the partition plate is driven by a swing motor to swing and move to the other side to block the top of the collection basket, thus guiding the material into the collection basket on the other side, thereby achieving material collection without stopping the machine.

[0017] 4. The laser cutting machine of the present invention uses an air duct and an air outlet to blow the air output by the cooling fan toward the cut material, which can help some materials that do not fall automatically to fall off by air. Attached Figure Description

[0020] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0021] like Figures 1-7As shown, this embodiment provides a laser cutting machine, including a machine base 1. Two cutting work areas are arranged side-by-side on the machine base 1. A cutting table 2 is installed on each cutting work area. A transfer roller 3 is movably mounted above the cutting table 2. A horizontal driving device 4 for driving the transfer roller 3 is provided on the cutting work area. The horizontal driving device 4 includes a guide sliding seat 401, a lead screw motor 402, and a transmission lead screw 403. The guide sliding seat 401 is slidably located above one side of the cutting table 2, and the lead screw motor 402 is mounted above the other side of the cutting table 2. The transmission screw 403 is connected to the screw motor 402 and extends along the moving direction of the guide slide seat 401. A guide rail is provided on the cutting work area for the guide slide seat 401 to slide. A screw seat 404 is fitted on the transmission screw 403. Lifting cylinders 405 are mounted on both the guide slide seat 401 and the screw seat 404. Both ends of the transmission roller 3 are rotatably connected to the lifting cylinders 405 on both sides, and one of the lifting cylinders 405 is equipped with a drive motor 406 to drive the transmission roller 3 to rotate. When feeding material, the end of the material is placed at the input of the cutting table 2, below the transmission roller 3. Then, the lifting cylinder 405 drives the transmission roller 3 to descend and clamp the material to the cutting table 2. Subsequently, the horizontal drive device 4 drives the lifting cylinder 405 to move the transmission roller 3 on the cutting table. After moving to the designated position, the drive motor 406 drives the transmission roller 3 to rotate, thus stably transmitting the material without the need for manual pressing, facilitating feeding.

[0022] Furthermore, the surface of the conveyor roller 3 is evenly covered with bristles 5. During rotation, the bristles 5 can clean the fine dust generated on the material after cutting. Specifically, the lifting cylinder 405 is equipped with a protective cover 6 on the conveyor roller 3. The protective cover 6 has a scraper 7 protruding from the surface facing the conveyor roller 3. The protective cover 6 has dust suction ports on both sides of the scraper 7. A vacuum cleaner 8 connected to the dust suction ports is installed between the guide sliding seat 401 and the lead screw seat 404. When the bristles 5 touch the scraper 7, the dust on the bristles 5 is scraped off by the scraper 7 and then sucked away through the dust suction ports in conjunction with the vacuum cleaner 8. This achieves the simultaneous conveying of materials and cleaning of the fabric, as well as cleaning of the bristles 5.

[0023] Furthermore, a chip collection and heat dissipation cavity 9 is provided below the cutting work area. A cooling fan 10 is installed on one side of the chip collection and heat dissipation cavity 9, and a chip collection drawer 11 is slidably provided at the bottom of the chip collection and heat dissipation cavity 9. The chip collection and heat dissipation cavity 9, together with the cooling fan 10, dissipates heat from the bottom of the cutting table 2. During the heat dissipation process, the dust is also drawn up and collected by the chip collection drawer 11.

[0024] Furthermore, a finished product collector 12 is placed at the output of machine 1. The finished product collector 12 includes a frame 1201 and two collection areas 1202 on the frame 1201 that are connected to the two cutting work areas. The cut material is collected through the two collection areas 1202.

[0025] Furthermore, a guide channel is provided within the storage area 1202, and an isolation plate 1203 is rotatably installed within the guide channel. The width of the isolation plate 1203 is the same as the width of the guide channel, and the length of the isolation plate 1203 is greater than half of its width. A swing motor 1204 is provided outside the storage area 1202 to drive the isolation plate 1203 to swing. Two collection baskets 1205 are placed below the guide channel. Specifically, multiple ventilation holes are provided on the side walls of the collection baskets 1205. The guide channel, in conjunction with the isolation plate 1203, guides the material and places it into the collection basket 1205. When the collection basket 1205 is full, the swing motor 1204 drives the isolation plate 1203 to swing, causing the isolation plate 1203 to swing to the other side, thereby blocking the top of the collection basket 1205 and guiding the material into the collection basket on the other side, achieving material collection without stopping the machine.

[0026] Furthermore, the storage area 1202 is provided with an air guide duct 1206 that connects to the air outlet 1207 of the cooling fan 10. The air guide duct 1206 extends to the top of the frame 1201 and is positioned above the storage area 1202. The frame 1201 is provided with an air outlet 1207 that communicates with the air guide duct 1206. The outlet of the air outlet 1207 faces the storage area 1202. A clamping guide roller is installed on the side of the storage area 1202 away from the machine base 1. Specifically, the air outlet 1207 of the cooling fan 10 has an extension pipe 1208. The inlet of the air guide duct 1206 is provided with a telescopic pipe that communicates with the extension pipe 1208. A locking device is installed on the telescopic pipe that is fixedly connected to the extension pipe 1208. Through the air guide duct 1206 and the air outlet 1207, the air output by the cooling fan 10 is blown towards the cut material, which can help some materials that do not fall automatically to fall down by airflow.

[0027] like Figure 1As shown, this embodiment provides a laser cutting machine, including a machine base 1. Two cutting work areas are arranged side-by-side on the machine base 1. A cutting table 2 is installed on each cutting work area. A transfer roller 3 is movably mounted above the cutting table 2. A horizontal driving device 4 for driving the transfer roller 3 is provided on the cutting work area. The horizontal driving device 4 includes a guide sliding seat 401, a lead screw motor 402, and a transmission lead screw 403. The guide sliding seat 401 is slidably located above one side of the cutting table 2, and the lead screw motor 402 is mounted above the other side of the cutting table 2. The transmission screw 403 is connected to the screw motor 402 and extends along the moving direction of the guide slide seat 401. A guide rail is provided on the cutting work area for the guide slide seat 401 to slide. A screw seat 404 is fitted on the transmission screw 403. Lifting cylinders 405 are mounted on both the guide slide seat 401 and the screw seat 404. Both ends of the transmission roller 3 are rotatably connected to the lifting cylinders 405 on both sides, and one of the lifting cylinders 405 is equipped with a drive motor 406 to drive the transmission roller 3 to rotate. When feeding material, the end of the material is placed at the input of the cutting table 2, below the transmission roller 3. Then, the lifting cylinder 405 drives the transmission roller 3 to descend and clamp the material to the cutting table 2. Subsequently, the horizontal drive device 4 drives the lifting cylinder 405 to move the transmission roller 3 on the cutting table. After moving to the designated position, the drive motor 406 drives the transmission roller 3 to rotate, thus stably transmitting the material without the need for manual pressing, facilitating feeding.

[0028] Furthermore, the surface of the conveyor roller 3 is evenly covered with bristles 5. During rotation, the bristles 5 can clean the fine dust generated on the material after cutting. Specifically, the lifting cylinder 405 is equipped with a protective cover 6 on the conveyor roller 3. The protective cover 6 has a scraper 7 protruding from the surface facing the conveyor roller 3. The protective cover 6 has dust suction ports on both sides of the scraper 7. A vacuum cleaner 8 connected to the dust suction ports is installed between the guide sliding seat 401 and the lead screw seat 404. When the bristles 5 touch the scraper 7, the dust on the bristles 5 is scraped off by the scraper 7 and then sucked away through the dust suction ports in conjunction with the vacuum cleaner 8. This achieves the simultaneous conveying of materials and cleaning of the fabric, as well as cleaning of the bristles 5.

[0029] Furthermore, a chip collection and heat dissipation cavity 9 is provided below the cutting work area. A cooling fan 10 is installed on one side of the chip collection and heat dissipation cavity 9, and a chip collection drawer 11 is slidably provided at the bottom of the chip collection and heat dissipation cavity 9. The chip collection and heat dissipation cavity 9, together with the cooling fan 10, dissipates heat from the bottom of the cutting table 2. During the heat dissipation process, the dust is also drawn up and collected by the chip collection drawer 11.

[0030] Furthermore, a finished product collector 12 is placed at the output of machine 1. The finished product collector 12 includes a frame 1201 and two collection areas 1202 on the frame 1201 that are connected to the two cutting work areas. The cut material is collected through the two collection areas 1202.

[0031] Furthermore, a guide channel is provided within the storage area 1202, and an isolation plate 1203 is rotatably installed within the guide channel. The width of the isolation plate 1203 is the same as the width of the guide channel, and the length of the isolation plate 1203 is greater than half of its width. A swing motor 1204 is provided outside the storage area 1202 to drive the isolation plate 1203 to swing. Two collection baskets 1205 are placed below the guide channel. Specifically, multiple ventilation holes are provided on the side walls of the collection baskets 1205. The guide channel, in conjunction with the isolation plate 1203, guides the material and places it into the collection basket 1205. When the collection basket 1205 is full, the swing motor 1204 drives the isolation plate 1203 to swing, causing the isolation plate 1203 to swing to the other side, thereby blocking the top of the collection basket 1205 and guiding the material into the collection basket on the other side, achieving material collection without stopping the machine.

[0032] Furthermore, the storage area 1202 is provided with an air guide duct 1206 that connects to the air outlet 1207 of the cooling fan 10. The air guide duct 1206 extends to the top of the frame 1201 and is positioned above the storage area 1202. The frame 1201 is provided with an air outlet 1207 that communicates with the air guide duct 1206. The outlet of the air outlet 1207 faces the storage area 1202. A clamping guide roller is installed on the side of the storage area 1202 away from the machine base 1. Specifically, the air outlet 1207 of the cooling fan 10 has an extension pipe 1208. The inlet of the air guide duct 1206 is provided with a telescopic pipe that communicates with the extension pipe 1208. A locking device is installed on the telescopic pipe that is fixedly connected to the extension pipe 1208. Through the air guide duct 1206 and the air outlet 1207, the air output by the cooling fan 10 is blown towards the cut material, which can help some materials that do not fall automatically to fall down by airflow.
