DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments.
[0021] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting this application.
[0022] like Figures 1-4 As shown, a debris splash prevention structure for precision cutting of small and medium-sized steel structures includes a workbench 1, support legs 2, a cutting box 3, a through port 8, a chip box 14, an exhaust fan 18, and a roller conveyor 19. The workbench 1 is provided with a roller conveyor 19 arranged along its length direction, the support legs 2 are arranged at the bottom of the workbench 1 and can support the workbench 1, the cutting box 3 is arranged at the top of the workbench 1 to form a closed cavity for debris to splash during cutting, a cutting structure is provided on the top of the cutting box 3, and through ports 8 are opened on both sides of the cutting box 3 for the steel structure to pass through, the chip box 14 is fixedly connected to the bottom of the workbench 1 for splashing debris, and the chip box 14 corresponds to the cutting box 3 up and down, an exhaust fan 18 is provided at the bottom of the chip box 14, and a filtering structure is provided in the chip box 14 to filter debris and exhaust gas.
[0023] Furthermore, the cutting structure includes a cylinder 4, a saw blade seat 5, a saw blade 6, and a motor 7. The cylinder 4 is vertically arranged on the top of the cutting box 3 and can be vertically extended and retracted to drive the cylinder 4 to rise and fall. The output end of the cylinder 4 extends into the cutting box 3 and is fixedly connected to the saw blade seat 5. The saw blade 6 is rotationally connected to the saw blade seat 5. The motor 7 is fixedly installed on the saw blade seat 5 and can drive the saw blade 6 to rotate.
[0024] Specifically, the cylinder 4 drives the saw blade seat 5 to rise and fall, and then the saw blade 6 follows the rise and fall, and is driven to rotate by the motor 7, so as to cut the steel structure transported by the roller conveyor 19 below.
[0025] Furthermore, the filtering structure includes a filter drawer 15, a handle 16, and a filter screen 17. The area on the workbench 1 located inside the cutting box 3 is densely provided with perforations 13 for passing debris. The filter drawer 15 is arranged in the chip collection box 14, and the front of the chip collection box 14 is provided with an opening for the filter drawer 15 to enter and exit, and the filter drawer 15 is slidably fitted with the chip collection box 14. A filter screen 17 is provided on the inside of the filter drawer 15, and a handle 16 is provided at the front of the filter drawer 15.
[0026] Specifically, the handle 16 can be used to push and pull the filter drawer 15 so that the filter drawer 15 can enter and exit the chip collection box 14. During the cutting process, the vacuum pump 18 is started, and the vacuum pump 18 draws air to absorb the flying debris. The debris falls on the filter screen 17 to collect the debris. At the same time, the filter screen 17 can filter the debris generated during the cutting process. Taking out the filter drawer 15 can clean the filter screen 17.
[0027] Further, the structure further comprises two shunt pipes 9, a plurality of air nozzles 10, a gas delivery pipe 11 and a fan 12. The two shunt pipes 9 are arranged above the through port 8 in the cutting box 3 respectively. The air nozzles 10 are arranged along the length direction of the shunt pipes 9. The gas delivery pipe 11 extends from outside of the cutting box 3 to inside of the cutting box 3 at both ends and communicates with the two shunt pipes 9 respectively. The fan 12 is installed on the outer wall of the cutting box 3 and the outlet of the fan 12 communicates with the middle part of the gas delivery pipe 11.
[0028] Specifically, the length direction of the shunt pipe 9 covers the width of the through port 8. The fan 12 generates gas and sends it into the gas delivery pipe 11, and then the gas is sprayed from the air nozzles 10. In this way, the debris splashed into the through port 8 is sent back into the cutting box 3 by the airflow, avoiding splashing outside the cutting box 3.
[0029] Further, the edge of the cutting box 3 abuts against the edge of the debris collecting box 14 to form a sealed space.
[0030] Further, the filter screen 17 is arranged horizontally and the edge is fixedly connected to the middle of the inner side of the filter extractor 15.
[0031] In the above structure, the steel member is placed on the roller conveyor 19 for conveying and can pass below the saw blade 6 through the through port 8. The height of the saw blade 6 can be adjusted by starting the expansion and contraction of the air cylinder 4. The saw blade 6 can be driven to rotate for cutting the steel member by electrifying the motor 7. The debris generated during the cutting process can be blocked inside the cutting box 3. At the same time, the air extractor 18 extracts the air in the cutting box 3, so that the gas and debris during the cutting process fall on the filter screen 17 and are filtered. The fan 12 is electrified to send air, which is then sprayed from the air nozzles 10. When the debris splashes, it is blown off, avoiding splashing outside the cutting box 3. The filter screen 17 can be cleaned by extracting the filter extractor 15.
[0032] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above examples. The above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
