Description

Technical Field

[0001] This utility model relates to the field of laser cutting machines, specifically a laser cutting machine for steel. Background Technology

[0002] Laser cutting machines are advanced processing equipment that play an important role in the manufacturing industry. They use laser beams to cut materials with high precision, and are characterized by accuracy, speed, and flexibility, making them an indispensable tool in modern industry. Laser cutting machines are used when cutting steel and other steel materials. A Chinese utility model patent (publication number: CN221494644U) discloses a cutting machine for processing wear-resistant steel plates, which solves the problem that existing laser cutting machines generate a large amount of waste when cutting wear-resistant steel plates. The waste falls to the bottom of the laser cutting machine, which is inconvenient to collect. Furthermore, a large amount of waste may prevent the waste on the surface of the laser cutting machine from falling to the bottom, thus affecting the cutting of wear-resistant steel plates.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, the waste generated by laser cutting is usually very hot. If it falls directly onto the conveyor belt, it will shorten the life of the conveyor belt and affect its normal use. Therefore, a steel laser cutting machine is proposed to address the above situation. Utility Model Content

[0004] To address the problem that the high temperature of waste generated during laser cutting in existing technologies can shorten the lifespan of the conveyor belt if it falls directly onto it, this invention proposes a steel laser cutting machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a steel laser cutting machine, including a cutting machine frame, a movable groove, a receiving plate and a first cylinder. The laser cutting machine is set on the top of the cutting machine frame, and a conveyor belt is set inside the cutting machine frame. There are two movable grooves, which are respectively opened on the two sides of the outer wall of the cutting machine frame.

[0006] The receiving plate is rotatably installed inside the cutting machine frame. Connecting blocks are fixed on both sides of the receiving plate, and the connecting blocks extend out of the movable groove. A ventilation pipe is fixed at one end of the top of the receiving plate. An air outlet pipe is provided on one side of the ventilation pipe, which connects to the inside of the receiving plate. An air inlet pipe is provided on the other side of the receiving plate, and one end of the air inlet pipe extends out of the cutting machine frame.

[0007] There are two first cylinders, which are rotatably connected to both sides of the cutting machine frame, and the moving end of the first cylinder is rotatably connected to the connecting block.

[0008] Preferably, the top of the receiving plate has a collection groove, and one side of the receiving plate has a discharge port communicating with the collection groove.

[0009] Preferably, a baffle is fixed to the top of the ventilation duct, the baffle is set at an angle, and the air outlet duct is located below the baffle.

[0010] Preferably, a through hole is provided on one side of the receiving plate to connect to the collection trough, and a second cylinder is fixed on one side of the receiving plate. The moving end of the second cylinder passes through the through hole and is fixed with a scraper, which slides in conjunction with the collection trough.

[0011] Preferably, a groove is provided at one end of the bottom of the receiving plate, and circular holes communicating with the groove are provided on both sides of the receiving plate, with a rotating roller rotatably connected to the two circular holes.

[0012] As a preferred option, the cutting frame has a through hole through which the air inlet pipe passes out of the cutting frame.

[0013] Preferably, both the cutting frame and the connecting block are equipped with rotating parts. The rotating parts include a pair of support plates, and a rotating shaft is rotatably connected between the pair of support plates. The fixed end and the moving end of the first cylinder are respectively fixed on the corresponding rotating shaft.

[0014] Preferably, a waste collection box is placed on one side of the cutting frame, and the waste collection box is located at the bottom of the conveyor belt.

[0015] The advantages of this utility model are:

[0016] 1. Through the structural design of the receiving plate, ventilation pipe, air outlet pipe, air inlet pipe and first cylinder, this utility model can cool the waste material after laser cutting before conveying and collecting it. This can prevent the high-temperature waste material from falling directly onto the conveyor belt and affecting the service life of the conveyor belt, thus extending the service life of the device and reducing the frequency of maintenance and replacement.

[0017] 2. Through the structural design of the receiving plate, connecting block, first cylinder and rotating roller, this utility model allows the receiving plate to tilt and slide onto the conveyor belt when the cooled waste material on the receiving plate is transported to the conveyor belt. This reduces the possibility that the waste material may have sharp edges or irregular shapes, which may cause impact load on the conveyor belt when falling and easily cause damage to the surface of the conveyor belt. At the same time, the scraper driven by the second cylinder can push the waste material on the receiving plate out, completing the effective unloading process. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a laser cutting machine for steel. (Refer to...) Figure 1 and Figure 4 A laser cutting machine for steel includes a cutting frame 1, a movable groove 100, a receiving plate 3 and a first cylinder 8. The laser cutting machine is mounted on the top of the cutting frame 1, and a conveyor belt 2 is installed inside the cutting frame 1.

[0027] The cutting frame 1 is equipped with a linear module that can move in the X, Y and Z axes, enabling precise movement in these directions and ensuring high-precision cutting of the steel by the laser beam.

[0028] The conveyor belt 2 is driven by drive rollers at both ends, which are driven by motors, enabling continuous and stable waste material conveying.

[0029] There are two movable slots 100, which are respectively opened on the two sides of the outer wall of the cutting machine frame 1.

[0030] The receiving plate 3 is rotatably installed inside the cutting machine frame 1 via a rotating shaft. Connecting blocks 7 are fixed on both sides of the receiving plate 3. The connecting blocks 7 extend out of the movable groove 100. A ventilation pipe 4 is fixed at one end of the top of the receiving plate 3. An air outlet pipe 5 is provided on one side of the ventilation pipe 4, which connects to the inside of the receiving plate 3. An air inlet pipe 6 is provided on the other side of the receiving plate 3, which connects to the receiving plate 3. One end of the air inlet pipe 6 extends out of the cutting machine frame 1 and connects to the external fan outlet.

[0031] There are two first cylinders 8, which are rotatably connected to both sides of the cutting machine frame 1, and the moving end of the first cylinder 8 is rotatably connected to the connecting block 7.

[0032] The dimensions of the movable groove 100 are designed to ensure that the connecting block 7 can make arc-shaped movements.

[0033] When the first cylinder 8 extends or retracts, it can drive the connecting block 7 to move up and down in the movable groove 100, thereby enabling the receiving plate 3 to rotate around its mounting axis. By adjusting the extension and retraction length of the first cylinder 8, the tilt angle of the receiving plate 3 can be changed to adapt to different waste collection and conveying needs. For example, when it is necessary to quickly convey waste to the conveyor belt 2, the receiving plate 3 can be adjusted to a larger tilt angle.

[0034] Reference Figure 2 and Figure 3 The top of the receiving plate 3 has a collection groove, and one side of the receiving plate 3 has a discharge port that communicates with the collection groove.

[0035] Reference Figure 3 A baffle is fixed to the top of the ventilation duct 4. The baffle is set at an angle, and the air outlet duct 5 is located below the baffle.

[0036] By setting up a baffle, the air outlet 5 can be protected to prevent waste from falling and damaging it. In order to improve the cooling effect, the air outlet of the air outlet 5 can be tilted towards the collection tank.

[0037] Reference Figure 2 and Figure 3 The receiving plate 3 has a through hole on one side that connects to the collection trough. A second cylinder 10 is fixed on one side of the receiving plate 3. The moving end of the second cylinder 10 passes through the through hole and is fixed with a scraper 11. The scraper 11 slides in cooperation with the collection trough.

[0038] When the second cylinder 10 extends or retracts, it can drive the scraper 11 to slide in the collection tank. When there is a lot of waste in the collection tank, the second cylinder 10 is activated and the scraper 11 pushes the waste towards the discharge port to ensure that the waste enters the conveyor belt 2 smoothly and prevents the waste from accumulating in the collection tank and affecting the subsequent collection work.

[0039] Reference Figure 2 , Figure 3 and Figure 4The receiving plate 3 has a groove 300 at one end of its bottom, and round holes communicating with the groove 300 are opened on both sides of the receiving plate 3. A rotating roller 9 is rotatably connected to the two round holes.

[0040] After the receiving plate 3 rotates, the rotating roller 9 can contact the surface of the conveyor belt 2. Through the rolling friction between the rotating roller 9 and the conveyor belt 2, the waste discharge effect is ensured, while the wear on the conveyor belt 2 can be further reduced.

[0041] Reference Figure 1 and Figure 2 A through hole is provided on the cutting machine frame 1, through which the air inlet pipe 6 passes out of the cutting machine frame 1.

[0042] Reference Figure 1 and Figure 2 Both the cutting frame 1 and the connecting block 7 are equipped with rotating parts. The rotating parts include a pair of support plates and a rotating shaft is rotatably connected between the pair of support plates. The fixed end and the moving end of the first cylinder 8 are respectively fixed on the corresponding rotating shaft.

[0043] Reference Figure 1 and Figure 2 A waste collection box 12 is placed on one side of the cutting frame 1, and the waste collection box 12 is located at the bottom of the conveyor belt 2.

[0044] Working principle: In use, first connect the power supply and switch of the electrical equipment in this device. After the steel material is placed on the cutting machine frame 1, it is cut by the laser cutting machine. The cut waste material falls from the unloading port at the top of the cutting machine frame 1 onto the receiving plate 3. Turn on the switch of the external fan. The fan works to deliver air into the air inlet pipe 6 and blows it out from each air outlet pipe 5 through the ventilation pipe 4. The waste material collected on the receiving plate 3 is cooled by the air blowing. After cooling, turn on the switch of the first cylinder 8. The first cylinder 8 works to move the telescopic end upward, which allows the receiving plate 3 to rotate and tilt through the rotating shaft, so that the rotating roller 9 contacts the surface of the conveyor belt 2. Then turn on the switch of the second cylinder 10 to make it work. The second cylinder 10 works to make the scraper 11 slide in the collection groove on the receiving plate 3, which pushes the waste material out and onto the conveyor belt 2. The conveyor belt 2 then transports it to the waste collection box 12.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
