[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The embodiment of the present application discloses a curtain wall unit cutting device.

[0022] Reference Figure 1 The curtain wall unit cutting device includes a workbench 5 and a bracket 11 slidably connected to the workbench 5, and the bracket 11 slides along the length direction of the workbench 5. The bracket 11 slides with the workbench 5 in the following manner: a slide groove for the bracket 11 to slide is provided on the workbench 5, so that the bracket 11 can slide in the slide groove.

[0023] A connecting block 17 is provided below the bracket 11, and a vertical cylinder 12 is fixedly connected to the bracket 11. The output shaft of the cylinder 12 faces downward and is fixedly connected to the connecting block 17. A protective cover 13 is fixedly connected to one side of the connecting block 17. The connecting block 17 is rotatably connected to a main shaft 18 through a bearing, and a cutting mechanism 1 is provided on the connecting block 17. The cutting mechanism 1 includes a motor 14 fixed to one side of the connecting block 17 by screws, a cutting knife 15 is coaxially fixed to one end of the main shaft 18, and the cutting knife 15 is rotatably connected to the protective cover 13 through a bearing. The output shaft of the motor 14 is coaxially fixed to the end of the main shaft 18 away from the cutting knife. The protective cover 13 is a hollow semicircular cover arranged on the outside of the cutting knife 15, which can prevent some debris from splashing and improve safety. The operation of the cylinder 12 can drive the protective cover 13 to move up and down together with the cutting knife 15 and the motor 14, and cooperate with the motor 14 to drive the cutting knife 15 to rotate at high speed, thereby playing the role of cutting the plate.

[0024] A positioning mechanism 4 is provided on the workbench 5. The positioning mechanism 4 includes two integrally formed support frames 41 welded to the workbench 5. The support frames 41 are L-shaped. A screw rod 42 is threadedly connected to the support frames 41. A pressing plate 43 is connected to one end of the screw rod 42 facing the workbench 5. When cutting the curtain wall, the position of the pressing plate 43 can be adjusted by adjusting the screw rod 42 to move up and down to fix the curtain wall, so that the cutting device can operate more stably.

[0025] Reference Figure 2 and Figure 3A water spray mechanism 16 is provided on the protective cover 13, and the water spray mechanism 16 includes two nozzles 161. The two nozzles 161 are detachably connected to the outer walls of both sides of the protective cover 13, and the nozzles 161 are connected to an external water storage tank with a water pump (not shown in the figure) through a water pipe, so that the nozzles 161 can spray water. When the nozzles 161 spray water, water droplets can adhere to the debris, so that the debris falls into the drainage groove 21 on the workbench 5 with the water droplets, and flows out of the workbench 5 along the drainage groove 21, which can reduce the splashing of debris and reduce the occurrence of safety problems.

[0026] The workbench 5 is provided with a collecting mechanism 2, which includes a plurality of drainage grooves 21 opened on the workbench 5, a plurality of drainage grooves 21 are opened along the length direction of the workbench 5, and a plurality of drainage grooves 21 are arranged equidistantly along the width direction of the workbench 5. The cross-section of the drainage grooves 21 is opened in a smooth arc shape, which can reduce the accumulation of debris in the drainage grooves 21, facilitate the circulation of water in the drainage grooves 21 and the cleaning of the drainage grooves 21. The two ends of the workbench 5 are respectively detachably connected with a hollow collecting box 22 with an open upper end by bolts, and the opening depth of the drainage groove 21 is set to be sloped from shallow to deep from the middle to the two ends. At the same time, the inner cavity of the collecting box 22 is connected to the drainage groove 21, so that the water flows along the drainage groove 21 to the collecting box 22. When water is sprayed, the water will flow along the slope of the drainage groove 21 to the collecting box 22 located at the two ends of the workbench 5, so as to achieve the purpose of collecting waste water and debris. By disassembling the collecting box 22, the waste water and debris can be cleaned in time. The collecting box 22 is detachable for use, which is convenient for replacing the collecting box 22.

[0027] Reference Figure 4 The lower surface of the workbench 5 is provided with a driving mechanism 3, which includes two fixed seats 31 fixedly connected to the lower surface of the workbench 5. The fixed seats 31 are rotatably connected to the screw rod 32 through a bearing. The fixed seats 31 are welded with a horizontal slide bar 33. The screw rod 32 is threadedly connected to a slider 34. The slider 34 is slidably connected to the slide rod 33. The slider 34 is fixedly connected to the bracket 11 through an integrally formed folding block. A servo motor 35 is fixedly connected to the lower surface of the workbench 5. The output shaft of the servo motor 35 is coaxially fixed with one end of the screw rod 32. When the servo motor 35 is in operation, the slider 34 can move along the direction of the slide rod 33 in cooperation with the limiting effect of the slide rod 33 on the slider 34, thereby driving the bracket on the workbench 5 and the cutting mechanism 1 to move.

[0028] Implementation principle:

[0029] The curtain wall panels are fixed by the positioning mechanism 4, and the panels of different thicknesses are adjusted and fixed by the pressing plate 43. The telescopic function of the cylinder 12 on the bracket 11 can be used to control the up and down displacement of the cutting mechanism 1 to cut the panels. The driving mechanism 3 drives the bracket 11 to slide, thereby driving the cutting mechanism 1 to move horizontally along the length direction of the workbench 5 to cut the panels. When the cutting device is in operation, the nozzles 161 arranged on both sides of the protective cover 13 spray water to reduce the splashing of debris when cutting the panels. The water droplets adhere to the debris and can bring the debris into the drainage trough 21 together, so that the debris flows along the slope of the drainage trough 21 to the collection boxes 22 at both ends of the workbench 5 to collect the debris and wastewater. A protective cover 13 is provided on the outside of the cutting knife 15 to prevent some debris from splashing out and reduce safety hazards.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
