[0002] Carpet is a covering that is laid on the floor, usually made of fiber materials such as wool, silk, cotton or synthetic fibers. Carpets can be used to decorate the interior environment, increase comfort and insulation, and reduce footsteps and wear and tear on the floor. Carpets come in a variety of colors, patterns and sizes to suit different rooms and decor styles. Carpets can be found in both homes and commercial places.

[0003] After long-term use, the existing carpet cutting machine knives will wear out and need to be replaced. The existing solution is to lift the knives through a lifting device and then install them. Because in the process of moving and installing the knives, the lifting may be unstable or out of control, increasing the possibility of injury to workers. Installing the knives after lifting them will increase the steps and complexity of the operation, and require extra time and effort to adjust the position and angle of the knives, which increases the difficulty of operation and reduces the efficiency of installation. In view of the above problems, a flip knife holder that is convenient for changing knives is proposed to solve them. Utility Model Content

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] Reference Figure 1-3 As shown, a tool turning frame for convenient tool changing comprises a first support frame 1 and a second support frame 6. The first support frame 1 is arranged on the left side of the second support frame 6. A conveyor belt 2 is fixedly installed on the upper end of the first support frame 1. Two wedge-shaped mounting blocks 3 are fixedly connected on the front and rear sides of the conveyor belt 2. The tops of the wedge-shaped mounting blocks 3 on the front and rear sides are fixedly connected with mounting strips 4. The inner sides of the two mounting strips 4 are rotatably connected with a plurality of first movable guide wheels 5. The top of the second support frame 6 is fixedly connected with a fixing plate 7. Hydraulic cylinders 8 are fixedly installed on the front and rear ends of the upper surface of the fixing plate 7 close to the conveyor belt 2. The output ends of the two hydraulic cylinders 8 are fixedly connected with fixing blocks 9. The inner sides of the two fixed blocks 9 are rotatably connected with a plurality of second movable guide wheels 22. The first movable guide wheel 5 and the second movable guide wheel 22 are both made of alloy material. This high-strength material enables the guide wheels to withstand greater loads and impact forces, thereby extending their service life.

[0020] Specifically, the tops of the two fixing blocks 9 are fixedly connected with a tool holder plate 10 , and the upper surface of the tool holder plate 10 is fixedly connected with at least three support blocks 11 . The support blocks 11 and the tool holder plate 10 are an integrally formed structure, thereby improving the overall rigidity of the tool holder plate 10 .

[0021] Preferably, a rotating support 12 is fixedly connected to the left side of the support block 11, and a rotating connecting ear 13 is rotatably connected inside the rotating support 12. A first cylinder 14 is fixedly installed on the bottom of the rotating connecting ear 13. Through the cooperation of the rotating support 12 and the rotating connecting ear 13, the first cylinder 14 is floatingly installed, allowing the first cylinder 14 to rotate freely within a certain range, thereby adapting to position changes during mechanical movement. This adaptability improves the connection flexibility between the cylinder and other components, so that the entire mechanical system can better cope with various complex working environments.

[0022] A limiting block 17 is fixedly connected to the left side of the tool holder plate 10 and just below the first cylinder 14. A moving block 15 is slidably connected inside the limiting block 17. The top of the moving block 15 is fixedly connected to the output end of the first cylinder 14. The bottom of the moving block 15 is rotatably connected to a clamping block 16.

[0023] It is worth mentioning that a second cylinder 18 is fixedly installed between the left side of the tool holder plate 10 and the two adjacent first cylinders 14, and the output end of the second cylinder 18 is fixedly connected to a clamping block 19. When cutting, the output end of the second cylinder 18 pushes the clamping block 19 to press tightly on the carpet, which can effectively prevent the carpet from deflecting during cutting and improve the cutting accuracy.

[0024] Preferably, a movable plate 20 is provided between the two fixed blocks 9, and the movable plate 20 is fixedly connected to the bottom of the tool holder plate 10 through a clamping block 16. A cutting knife 21 is fixedly installed at the bottom of the movable plate 20. The clamping block 16 is L-shaped, and the flatness of its bottom is the same as that of the movable plate 20, so that it can better fit the bottom surface of the movable plate 20. The cutting knife 21 is made of alloy steel.

[0025] Specifically, the first movable guide wheel 5 and the second movable guide wheel 22 are located on the same horizontal line, and the hydraulic cylinder 8 is used to control the relative position of the second movable guide wheel 22 and the first movable guide wheel 5, which can facilitate the pushing of the movable plate 20 to prevent the movable plate 20 from being unable to be pushed to the upper surface of the second movable guide wheel 22.

[0026] Working principle: When replacing the tool, first, the output end of the first cylinder 14 pushes the moving block 15 to slide inside the limit block 17, and then the clamping block 16 is rotated upward to make the moving plate 20 detach from the bottom of the tool holder plate 10 and fall onto the second moving guide wheel 22, and then the moving plate 20 is pushed onto the first moving guide wheel 5, and then the cutting knife 21 can be removed. When installing the cutting knife 21, first place the moving plate 20 on the first moving guide wheel 5, and then push the moving plate 20 to the bottom of the tool holder plate 10, the output end of the first cylinder 14 pushes the moving block 15 to move downward, and then the clamping block 16 is rotated to Figure 2 After reaching the position shown, the output end of the first cylinder 14 pulls the moving block 15 to move upward, and the moving plate 20 is fixed by the clamping block 16, and the installation is completed.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
