They are used to block harmful substances such as laser radiation and spatter generated during the laser cutting process, protecting the safety of operators and surrounding equipment from damage. They can effectively block laser radiation to prevent damage to the operator's eyes and skin, and block molten slag and sparks that splash during the cutting process to prevent fires or burns.

[0003] The fixed position of the protective baffle on the existing laser cutting machine affects the cutting operation and is not easy to replace, resulting in poor performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a protective baffle for laser cutting machines, which effectively solves the problems of fixed position of existing protective baffles for laser cutting machines, which affect the cutting operation and are inconvenient to replace, resulting in poor performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective baffle for a laser cutting machine, comprising a mounting frame, a baffle body inserted inside the mounting frame, a movable door at the bottom of the mounting frame, one end of the movable door being hinged to the bottom of the mounting frame via a hinge, the other end of the movable door being fixedly connected to the bottom of the mounting frame via a latch, push strips fixedly installed at the upper ends of both sides of the mounting frame, two limiting holes respectively opened at the upper parts of both sides of the mounting frame, moving strips provided at the lower parts of both sides of the mounting frame, rectangular grooves opened at the lower ends of both sides of the baffle body, push plates provided at one end of each of the two rectangular grooves, telescopic springs provided inside each of the two rectangular grooves, and both ends of the two telescopic springs being fixedly connected to the inner wall of one end of each of the two rectangular grooves and the side of each push plate that is close to each other;

[0006] A rectangular rod is fixedly installed on the side of each of the two pushing plates that are far apart from each other. The ends of the two rectangular rods that are far apart from each other are respectively fixedly connected to two moving strips. An inclined block adapted to the two pushing strips is fixedly installed in the middle of the side of each of the two moving strips that are far apart from each other. Limiting rods adapted to four limiting holes are fixedly installed at both ends of the side of each of the two moving strips that are close to each other. A support plate is fixedly installed on the upper part of one side of the mounting frame through a support block. A drive motor is fixedly installed on the upper part of the support plate on the side close to the mounting frame. The output end of the drive motor is provided with a transmission component, which is connected to the baffle body in a transmission manner.

[0007] Preferably, the transmission assembly includes a driving bevel gear, which is fixedly installed at the output end of the drive motor. A driven bevel gear is meshed with one side of the surface of the driving bevel gear. A shaft is fixedly installed in the middle of the driven bevel gear. Transmission gears are fixedly installed at both ends of the shaft. Positioning seats are rotatably installed at the ends of the two transmission gears that are far apart from each other. One end of each positioning seat is fixedly connected to the mounting frame.

[0008] Preferably, two strip grooves are provided on one side of the mounting frame, and two transmission racks are fixedly installed on one side of the baffle body. The two transmission racks are installed inside the two strip grooves, and the two transmission racks are meshed with two transmission pinions.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator starts the drive motor to run in the forward direction. When the drive motor runs in the forward direction, it drives the driven bevel gear to rotate through the active bevel gear. When the driven bevel gear rotates, it drives the two transmission gear columns to rotate along the two positioning seats through the shaft. When the two transmission gear columns rotate, they drive the baffle body to move upward and extend out for protection through the two transmission racks.

[0010] When the baffle body moves into position, the two pushing bars push against each other, and the two inclined blocks cause the two moving bars to move towards each other. When the two moving bars move, they drive the pushing plate to move into the rectangular groove through the rectangular rod and simultaneously squeeze the telescopic spring. The elastic force of the telescopic spring enables the moving bars to have the ability to elastically reset. When the two moving bars move towards each other, they will drive the two limiting rods to insert into the two limiting holes to limit the movement, so as to ensure the stability of the baffle body extending out.

[0011] During disassembly, the operator opens the movable door and then starts the drive motor to run in reverse. When the drive motor runs in reverse, it can directly move the baffle body down to the outside of the mounting frame through two transmission racks, thereby quickly completing the disassembly and replacement. This allows the protective baffle of the laser cutting machine to be extended or retracted as needed, avoiding obstruction of the cutting operation and facilitating replacement, resulting in excellent performance.
