[0019] In one embodiment, Figure 2 As shown, the first cleaning mechanism 4 includes a cleaning brush assembly 41, one end of the cleaning brush assembly 41 (which can be understood as the lower end) is slidably arranged with the inner side wall of the first door panel 2, so that during the movement of the cleaning brush assembly 41, the cutting fluid and iron filings adhered to the inner surface of the first door panel 2 can be cleaned; the other end of the cleaning brush assembly 41 (which can be understood as the upper end) is connected to the first supporting plate 42, and the first supporting plate 42 is connected to the rectangular frame 43, and the two opposite side walls of the rectangular frame 43 (which can be understood as the inner top wall and the inner bottom wall) are fixedly provided with spur racks 44, and a missing gear 45 is provided between the two spur racks 44, and the missing gear 45 is alternately meshed with the two spur racks 44, and the missing gear 45 is fixedly sleeved on the outside of the first rotating rod 46, and the first rotating rod 46 is fixedly connected to the driving end of the driving motor 47, and the driving The driving motor 47 is fixedly arranged on the inner wall of the machine tool housing 1. When working, the starting of the driving motor 47 will rotate the missing gear 45 through the first rotating rod 46. The rotation of the missing gear 45 will alternately mesh with the two spur racks 44. When the missing gear 45 meshes with the upper spur rack 44, the rectangular frame 43 will move downward through the upper spur rack 44. When the missing gear 45 meshes with the lower spur rack 44, the rectangular frame 43 will move upward through the lower spur rack 44. The alternating meshing of the missing gear 45 with the two spur racks 44 will cause the rectangular frame 43 to move up and down cyclically. During the cyclic up and down movement of the rectangular frame 43, the cleaning brush assembly 41 will move up and down through the first supporting plate 42. During the movement of the cleaning brush assembly 41, the cutting fluid and iron filings adhering to the inner surface of the first door panel 2 can be cleaned.

[0025] In one embodiment, Figure 7As shown, the second guide support assembly 65 includes a second guide support rod 651, a second guide support tube 652 and a second guide support spring 653. The second guide support rod 651 is movably inserted in the second guide support tube 652, and the second guide support spring 653 is wound outside the second guide support rod 651, and one end of the second guide support spring 653 (which can be understood as the upper end) is fixedly connected to the side wall of the second guide support rod 651, and the other end of the second guide support spring 653 (which can be understood as the lower end) is fixedly connected to the outer side wall of the second guide support tube 652.

[0026] The provision of the second guide support assembly 65 in this embodiment can not only provide vibration force for the equipment, but also provide a guiding function for the combined structure of the first supporting block 62, the sliding rod 63 and the second supporting block 64, so that the combined structure of the first supporting block 62, the sliding rod 63 and the second supporting block 64 can only move in the vertical direction. At the same time, it can also provide a reset force for the reset process of the combined structure of the first supporting block 62, the sliding rod 63 and the second supporting block 64.

[0027] In one embodiment, Figure 8 As shown, the environment-friendly CNC machine tool based on PLC control also includes a knocking mechanism 7.

M knocking components are arranged on the circumference of the rotating disk 72, and M is a positive integer greater than or equal to 1. Specifically, the knocking components can be set to 1, 2, 3 or more; when working, the upward or downward movement of the second supporting block 64 will cause the rotating disk 72 to rotate, and the rotation of the rotating disk 72 will cause the knocking components to rotate, and the rotation of the knocking components will realize the knocking of the first supporting plate 42.

[0028] In order to enable the rotating disk 72 to perform 360° circumferential rotation, in one embodiment, the knocking assembly includes a movable groove 75 provided on the rotating disk 72, a knocking rod 77 is movably provided in the movable groove 75, one end of the knocking rod 77 located in the movable groove 75 is fixedly connected to a reset spring 76, the free end of the reset spring 76 is fixedly connected to the side wall of the movable groove 75, and one end of the knocking rod 77 located outside the movable groove 75 is configured as a round head structure. The structural design of the knocking assembly in this embodiment is reasonable. During the rotation of the rotating disk 72, the knocking assembly will rotate with it. During the rotation of the knocking assembly, the knocking rod 77 will hit the first supporting plate 42, thereby generating a knocking effect.
