Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, in particular to a laser cutting machine for recycling metal materials. Background Art

[0002] Global metal consumption continues to rise, while primary mineral resources are becoming increasingly depleted. Metal recycling has become a key path to alleviating resource pressures. Traditional metal recycling relies on manual sorting and mechanical cutting, which suffers from low efficiency, poor precision, and significant material waste. This makes it difficult to meet modern industry's demand for high-purity recycled metals. Laser cutting technology, with its high precision and flexibility, has become a core direction for technological upgrades in the metal recycling sector. The widespread use of laser cutting machines has driven the manufacturing industry's transition from "mass production" to "customized manufacturing," playing a particularly key role in strategic industries such as new energy and semiconductors. Laser cutting machines use a high-energy-density laser beam as a "cutting tool," achieving precise cutting by locally melting, vaporizing, or fracturing materials through thermal or non-thermal effects. The core of a laser cutting machine is to focus the laser beam into an extremely small spot on the workpiece using a focusing lens. This spot generates extremely high energy density, rapidly heating the workpiece to its melting or vaporization temperature, enabling laser cutting. Laser cutting, in essence, combines laser technology with material processing and is a crucial component of advanced manufacturing technology.

[0003] When existing laser cutting machines are used to cut metal materials of different thicknesses, they may frequently need to replace laser cutting heads with different energy densities. They are unable to make adaptive adjustments for different thicknesses, which greatly reduces work efficiency. Purchasing different laser cutting heads will increase costs. In addition, the temperature of the metal workpiece is very high after laser cutting, and it needs to wait for cooling before sorting. Whether the workpiece has been cooled still needs to be judged by the user, which can easily cause damage due to misjudgment. Summary of the Invention

[0011] The present invention provides a laser cutting machine for recycling metal materials. It has the following beneficial effects: 1. When the laser cutting machine for metal material recycling is used, metal fragments of different particle sizes will be generated after laser cutting of metal workpieces. After passing through the first filter hole on the belt of the belt conveyor, they will fall into the first collection box. Then the vibration motor is started to vibrate the first collection box, and the smaller metal fragments in the first collection box will be vibrated out from the second filter hole and fall into the second collection box, thereby completing the collection of metal fragments of different particle sizes. When the accumulation reaches a certain level, the collection box can be pulled out for processing, thereby realizing material classification and improving the utilization rate of metal resources.

[0012] 2. When the laser cutting machine for recycling metal materials is in use, the metal workpiece is clamped and fixed for laser cutting. After the cut workpiece is completed, it needs to be transported to a metal cooling box for cooling. Therefore, a lifting device is provided to start the second stepper motor. The drive shaft of the second stepper motor rotates to drive the drive gear to rotate. The drive gear rotates to drive the rack to rise. The rising rack drives the lifting rod to slide upward inside the fixed sleeve. The lifting rod slides upward to drive the supporting plate to move upward. The upward movement of the supporting plate drives the clamping device to move upward, so that the workpiece can be transported to one end close to the metal cooling box via the belt conveyor for final cooling, thereby improving work efficiency.

[0013] 3. When the laser cutting machine for recycling metal materials is used, the third stepper motor is started, and the driving shaft of the third stepper motor rotates to drive the gear column to rotate, and the rotation of the gear column drives the first sliding gear rod and the second sliding gear rod to move in opposite directions, and the first sliding gear rod and the second sliding gear rod move in opposite directions respectively, driving the first sliding block and the second sliding block to slide in opposite directions on the inner walls of the first slide groove and the second slide groove, so that the first sliding gear rod and the second sliding gear rod move in opposite directions and drive the first fixed splint and the second fixed splint to move in opposite directions, and the first fixed splint and the second fixed splint move in opposite directions and drive the third sliding block and the fourth sliding block to move in opposite directions on the first slide rail and the second slide rail, so that metal processing parts of different sizes can be clamped and fixed, thereby improving work efficiency and avoiding the reduction of cutting accuracy caused by the offset of the workpiece during the cutting process.

[0014] 4. When the laser cutting machine for recycling metal materials is in use, the infrared scanner performs an infrared scan on the workpiece to be processed in front, calculates the accurate position and controls the first electric slider, the second electric slider and the pneumatic piston rod. The first electric slider is controlled to slide up and down on the inner wall of the third slide groove. The up and down sliding of the first electric slider drives the sliding beam to slide up and down. At the same time, the second electric slider is controlled to slide on the inner wall of the fourth slide groove. The sliding of the second electric slider drives the connecting plate to move. The movement of the connecting plate drives the pneumatic piston rod to move. At the same time, the pneumatic piston rod controls the extension and contraction of the movable end according to the data of the infrared scanner. Finally, the laser cutting device can be controlled to move to the workpiece for laser cutting, thereby making the laser cutting process more accurate and less likely to collide with the workpiece and cause damage to the workpiece.

[0015] 5. When using the laser cutting machine for recycling metal materials, the beam energy intensity required for metal processing parts of various thicknesses is input into the system in advance, and then the third electric slider is started. The third electric slider slides up and down on the slide rod. The up and down sliding of the third electric slider drives the focusing lens to slide up and down on the inner wall of the laser cover. Therefore, the movement of the focusing lens can be controlled by controlling the up and down movement of the third electric slider to further control the focal length. Therefore, the intensity of the beam energy can be changed by automatically adjusting the focal length, which reduces manual intervention, realizes automatic operation, and improves work efficiency.

[0016] 6. When the laser cutting machine for recycling metal materials is used, after the laser cutting is completed, the surface temperature of the metal workpiece will remain high for a long time due to the laser cutting, so it can be transported to the inside of the cooling box by a belt conveyor. Because there is water inside the cooling box, the water has a buffering effect, which avoids the damage caused by the metal workpiece after falling. The high-pressure water pump on the side of the cooling box extracts the water with increased temperature after cooling, and transports it to the top of the inner wall of the cooling box through the water pipe and re-sprays it into the cooling box. This cycle is repeated, so that the flow of water can be used to take away heat, thereby improving the cooling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
