DETAILED DESCRIPTION

[0020] The utility model provides a modular damper structure of a laser cutting machine. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0021] See also Figure 1-Figure 3 The utility model provides a modular damper structure of a laser cutting machine, comprising an exhaust box 1 with a front opening and a filter plate 2 connected to the front opening, the exhaust box 1 is divided into an exhaust zone 12 and a control zone 13, the exhaust box 1 is provided with an exhaust port 11 on the back of the exhaust zone 12, the exhaust port 11 is controlled to open and close by a movable damper plate 3, and a driving component 4 connected to the damper plate 3 is provided in the control zone 13; a filter hole 21 connected to the exhaust zone 12 is provided on the filter plate 2.

[0022] Compared with the prior art, the damper structure provided by the utility model integrates the filter plate 2, damper plate 3 and drive assembly 4 in the exhaust box 1, so that the damper structure forms a modular damper structure; the reliability and stability of the drive assembly 4 driving the damper plate 3 to open and close have been tested in advance, so when installing on site, the staff does not need to spend time debugging again, and only needs to embed the modular damper structure into the installation port reserved for the bed and fix it, thereby improving the installation efficiency of the damper structure and facilitating the overall disassembly for maintenance later. In addition, the drive assembly 4 is set in the control range 13 to be free from pollution such as smoke, debris and welding slag, prolonging the service life and ensuring the stability of long-term operation.

[0023] During the exhaust dust removal process, the drive assembly 4 starts and drives the damper plate 3 to open the exhaust port 11. The debris and dust generated during the cutting process first pass through the filter plate 2 and are then sucked into the exhaust duct from the exhaust port 11 and discharged. The larger iron slag and waste generated by the cutting are filtered by the filter plate 2 and cannot enter the exhaust duct, causing the exhaust duct to be blocked. When the dust removal is completed or the cutting head leaves, the drive assembly 4 drives the damper plate 3 to reset, so that the damper plate 3 re-seals the exhaust port 11, that is, the damper plate 3 closes the exhaust port 11, and the area where the exhaust port 11 is located will no longer be exhausted and dusted.

[0024] In fact, the area of ​​the filter plate 2 is larger than the area of ​​the reserved installation opening of the bed. The edge of the filter plate 2 will form a sealed edge after being attached to the bed, which effectively prevents byproducts such as smoke and debris from leaking from the installation gap and enhances the sealing performance of the exhaust system. The filter plate 2 is provided with a plurality of mounting holes 22 near the edge. The plurality of mounting holes 22 and screws are used to ensure the stable installation of the modular damper structure on the bed, thereby improving the stability of the overall structure. The use of screw fixing makes the disassembly and assembly of the modular damper structure more convenient, and installation or maintenance work can be easily completed without special tools or complicated operations.

[0025] The exhaust zone 12 and the control zone 13 are distributed on the left and right and separated by the vertical partition 5, which effectively prevents smoke, debris and other by-products generated during the cutting process from invading the control zone 13, protects the drive component 4 from pollution, and ensures the long-term operation stability and reliability of the drive component 4.

[0026] In addition, the separate layout of the exhaust section 12 and the control section 13, combined with a reasonable airflow guide design, can more effectively guide the smoke and debris generated during the cutting process directly into the exhaust section 12, reducing the chance of airflow detouring in the machine body, improving the exhaust efficiency, accelerating the discharge of dust and harmful substances, and optimizing the working environment.

[0027] Specifically, the damper plate 3 includes a main body 31 and a rotating shaft 32 extending transversely and fixed in the middle of the main body 31. One end of the rotating shaft 32 is rotatably connected to the side wall of the exhaust box 1, and the other end is rotatably connected to the vertical partition 5 of the exhaust box 1 and extends through the control zone 13. The rotating shaft 32 serves as the rotation center of the damper plate 3, ensuring that the damper plate 3 can move smoothly along a preset track during the opening and closing process, avoiding the possible deviation or jamming of the traditional damper plate 3, thereby improving the sealing effect of the exhaust port 11 and reducing the risk of air leakage and dust leakage. The combined design of the main body 31 and the rotating shaft 32 increases the overall rigidity and stability of the damper plate 3, especially in the application of the exhaust port 11 with a larger size, which can effectively resist the impact of the air flow generated during the cutting process, maintain the flatness and sealing performance of the damper plate 3, and reduce the possibility of deformation and damage.

[0028] In this embodiment, one end of the rotating shaft 32 is matched with the perforated gap on the side wall of the exhaust box 1, and the other end is matched with the perforated gap on the vertical partition 5 of the exhaust box 1, so that the rotating shaft 32 can rotate smoothly. Of course, a bearing seat can be provided on the side wall and the vertical partition 5 of the exhaust box 1, and the bearing seat is rotatably connected to both ends of the rotating shaft 32 to ensure that the rotating shaft 32 rotates more smoothly.

[0029] In order to ensure the timeliness and accuracy of the opening and closing of the damper plate 3, the rotating shaft 32 is provided with a connecting rod 33 at the end located in the control zone 13, and the driving assembly 4 includes a support 41, a cylinder 42 and a joint 43 provided at the end of the piston rod of the cylinder 42. The support 41 is provided on the bottom surface of the exhaust box 1 and the support 41 is hinged to the cylinder body of the cylinder 42, and the joint 43 is hinged to the connecting rod 33. The cylinder 42 has a high output force and fast response characteristics. Through the hinge connection of the joint 43 and the connecting rod 33, the linear motion of the cylinder 42 can be directly and quickly converted into the rotational motion of the damper plate 3, thereby improving the driving efficiency and response speed.

[0030] Preferably, the exhaust box 1 is provided with an operation window 14 on the back of the control zone 13. The staff can observe the internal situation in the control zone 13 and reach in to complete the wiring and pipe connection operation.

[0031] Preferably, the operation window 14 is covered by a dustproof flap 6, which can effectively prevent dust, impurities and harmful substances in the external environment from entering the control zone 13, protect the internal drive components 4, circuits and other precision components from pollution, extend the service life of the device, and ensure the stable operation of the device. When the operation window 14 needs to be operated, the dustproof flap 6 is flipped up to reach into the control zone 13.

[0032] Preferably, the exhaust box 1 is provided with a wiring hole 15 on the bottom surface of the control section 13. The design of the wiring hole 15 allows the air pipe to be directly connected to the control section 13 from the bottom without affecting other components, and to establish a connection with the cylinder 42, thereby avoiding the air pipe from being entangled inside the control section 13, optimizing the air path layout, and improving space utilization.
