Description

Technical Field

[0001] This utility model relates to the field of laser screen making machines, and more specifically, it relates to a smoke extraction structure for a laser screen making machine. Background Technology

[0002] A laser screen printing machine is a specialized device that uses a high-energy laser beam to punch holes in a circular screen of a specific model according to a preset pattern, thereby creating a printing template.

[0003] When the laser screen making machine is working, the circular mesh is first stably clamped by a special fixture and rotated at a uniform speed to ensure that the area to be processed on the surface of the circular mesh is always in a flat and fixed processing position. Then, the laser generator produces a high-energy laser beam, which is focused by the optical system and precisely applied to the surface of the circular mesh. The laser energy instantly melts and vaporizes the material to achieve the opening of the specified aperture and shape. At the same time, the laser head moves along the axis of the circular mesh according to the preset pattern path. In conjunction with the rotation of the circular mesh, a continuous and uniform mesh pattern is finally processed on the surface of the circular mesh. When the laser generator punches holes in the circular mesh, it will generate smoke. Large holes over a long period of time will affect the environment around the laser screen making machine.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a smoke-smoking structure for a laser screen making machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a smoke-emitting structure for a laser screen making machine, comprising a body, wherein multiple linear slides are slidably connected to the body, an mounting block is fixedly connected to the linear slides, a cavity is provided in the mounting block, and a laser generator is installed in the cavity; An arc-shaped strip and a smoke exhaust pipe are fixedly connected to opposite sides of the mounting block. An arc-shaped groove is formed on the inner peripheral wall of the arc-shaped strip, and a rectangular groove communicating with the cavity is formed on the inner wall of the arc-shaped groove. The laser generator is aligned with the rectangular groove, and one end of the smoke exhaust pipe is connected to the cavity.

[0007] The present invention is further configured such that: a flexible pipe is fixedly connected to the other end of the exhaust pipe, and a negative pressure device is fixedly connected to the other end of the flexible pipe.

[0008] The present invention is further configured such that: an adsorption box is provided between the negative pressure device and the flexible tube, and activated carbon is provided inside the adsorption box.

[0009] The present invention is further configured such that the depth of the arc-shaped groove is smaller as it approaches the two ends of the arc-shaped strip.

[0010] The present invention is further configured such that: a linear motor is also provided on the linear slide, the linear motor can drive the mounting block to move back and forth, and the direction in which the linear motor drives the mounting block to move is perpendicular to the direction of sliding of the linear slide.

[0011] The present invention is further configured such that: a support frame for supporting the exhaust pipe is fixed on the linear slide, and a fixed pulley that contacts the exhaust pipe is provided on the support frame.

[0012] In summary, this utility model has the following beneficial effects: The negative pressure device generates negative pressure, enabling the exhaust pipe to absorb smoke. The arc-shaped strip is positioned close to the circular mesh, and the arc-shaped groove serves as a channel for conducting smoke. This allows the smoke generated by the laser generator when it makes an opening to enter the rectangular groove along the arc-shaped groove and then be discharged through the exhaust pipe in the cavity. This configuration allows the generated smoke to be discharged through the exhaust pipe, reducing the impact of smoke on the surrounding environment. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A smoke extraction structure for a laser mesh fabrication machine, such as Figure 1 , Figure 2 and Figure 5As shown, the device includes a body with multiple linear slides 1 slidably connected to it. In this embodiment, there are three linear slides 1. A mounting block 2 is fixedly connected to each linear slide 1. A cavity is provided inside the mounting block 2, and a laser generator 3 is installed inside the cavity. The body also has two clamps 13 for clamping the ends of the circular mesh, one of which is an active clamp 13 that can drive the circular mesh to rotate. During rotation, the laser generator 3 emits a laser to drill holes in the circular mesh. Arc-shaped strips 4 and exhaust pipes 5 are fixedly connected to opposite sides of the mounting block 2. The arc-shaped strips 4 are used to fit against the circular mesh. Arc-shaped grooves 6 are formed on the inner circumferential wall of the arc-shaped strips 4, and arc-shaped grooves 6 are formed on the inner wall of the arc-shaped grooves 6 that connect to the cavity. A rectangular groove 7 is formed, with the laser generator 3 aligned with the rectangular groove 7. One end of the exhaust pipe 5 is connected to the cavity, and a flexible pipe 8 is fixedly connected to the other end of the exhaust pipe 5. A negative pressure device 9 is fixedly connected to the other end of the flexible pipe 8. In this embodiment, the negative pressure device 9 can be a centrifugal fan. The negative pressure device 9 generates negative pressure, thereby enabling the exhaust pipe 5 to absorb flue gas. The arc-shaped strip 4 is positioned close to the circular mesh, and the arc-shaped groove 6 serves as a channel for conducting flue gas. This allows the flue gas generated by the laser generator 3 when it makes an opening to enter the rectangular groove 7 along the arc-shaped groove 6 and then be discharged through the exhaust pipe 5 in the cavity. The above arrangement enables the generated flue gas to be discharged through the exhaust pipe 5, reducing the impact of flue gas on the surrounding environment.

[0017] like Figure 2 , Figure 3 and Figure 4As shown, an adsorption box 10 is also installed between the negative pressure device 9 and the flexible tube 8. Activated carbon is installed inside the adsorption box 10. Harmful gases, vapors, and odors are generated during laser processing. The activated carbon adsorption process can achieve deep purification of the exhaust gas, reducing its impact on the external environment and making it more environmentally friendly. The number of adsorption boxes 10 is equal to the number of linear slides 1. The flexible tube 8 provides a buffer space for the movement of the linear slide 1, allowing it to slide smoothly. The depth of the arc groove 6 decreases closer to the ends of the arc strip 4, reducing the possibility of flue gas escaping from both ends of the arc groove 6. A linear motor is also installed on the linear slide 1, which drives the mounting block 2 to move back and forth. The moving mounting block 2 moves in a direction perpendicular to the sliding direction of the linear slide table 1. The stator of the linear motor is fixed on the linear slide table 1, and the mover of the linear motor is directly fixed to the bottom of the mounting block 2 by bolts. When the linear motor is powered on, its mover, as the only moving segment, will generate precise linear motion, thereby directly driving the entire mounting block 2, laser generator 3, and arc strip 4 fixed to it to move back and forth together, realizing fine adjustment of the processing distance. The linear slide table 1 is also fixed with a support frame 11 for supporting the exhaust pipe. The support frame 11 is equipped with a fixed pulley 12 that contacts the exhaust pipe 5. Since the exhaust pipe 5 will also move back and forth during the movement, the fixed pulley 12 reduces the friction between the support frame 11 and the exhaust pipe 5.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
