In order to solve the problem that the cutting knife of the carton processing and cutting device is not provided with a protective structure when in use, thereby reducing the safety of the device, please refer to Figures 1 to 4. The structure of the device body is a processing table 1 and a cutting blade 20 for cutting cardboard. Linear motors 8 are installed on both sides of the processing table 1. The moving parts of the two linear motors 8 are fixedly connected to a U-shaped inverted support plate 9. The support plate 9 provides support. A linear motor 2 10 is installed at the bottom end of the support plate 9. The moving part of the linear motor 2 10 is installed with an electric telescopic rod 11. Power is provided by the linear motor 1 8 and the linear motor 2 10 and the electric telescopic rod 11. The cutting blade 20 is flexibly moved during the transmission process to achieve multi-position cutting of the cardboard. The moving end of the electric telescopic rod 11 is fixedly connected to a rotating motor 12.

The set rotating motor 12 provides power, which is convenient for adjusting the cutting direction of the cutting blade 20, adapting to the cutting of different angles of the cardboard, and improving the convenience of using the device. The output shaft of the rotating motor 12 is provided with a cutting component 2, and the cutting component 2 includes a rotating plate 3 and a protective cover 6. The set protective cover 6 provides a shielding effect to prevent the safety hazard caused by the cutting blade 20 when cutting the cardboard, and provides a protective effect, thereby improving the safety of using the cutting device. The top of the rotating plate 3 is fixedly connected to the output shaft of the rotating motor 12, so that the rotating plate 3 is driven to rotate by the output shaft of the rotating motor 12. The bottom end of the rotating plate 3 is fixedly connected to a connecting rod 4, and the bottom end of the connecting rod 4 is fixedly connected to a square movable plate 5. The set connecting rod 4 realizes the synchronous rotation and movement of the rotating plate 3 and the movable plate 5, and the side of the movable plate 5 is slidably connected to the protective cover 6.

The movable plate 5 is arranged in a square shape and fits with the inner wall of the protective cover 6 to prevent the movable plate 5 from rotating relative to the inner wall of the protective cover 6 when the movable plate 5 moves, thereby improving the functional structural stability of the device. The side of the connecting rod 4 is slidably connected to the protective cover 6 to enhance the movement stability of the protective cover 6. The protective cover 6 that is convenient for longitudinal movement is arranged to provide a shielding and protective effect while preventing it from affecting the normal cutting of the cardboard by the cutting blade 20, thereby improving the functional structural stability of the device. A booster spring 7 is sleeved on the side of the connecting rod 4. The top and bottom ends of the booster spring 7 are fixedly connected to the rotating plate 3 and the protective cover 6 respectively. The booster spring 7 provides an elastic thrust to prevent the protective cover 6 from shaking during the shielding and protection process, thereby improving the shielding and protection effect of the protective cover 6, and further improving the safety of the cutting device for cutting cardboard.

A U-shaped fixed plate 14 is fixedly connected to the bottom end of the movable plate 5. Both end surfaces of the fixed plate 14 are fixedly connected to limit bearings 15 through the through grooves. The inner ring sides of the two limit bearings 15 are fixedly connected to threaded rods 16. The two limit bearings 15 are convenient for fixing the rotation position of the threaded rod 16, and at the same time, it is convenient to improve the relative rotation stability between the threaded rod 16 and the fixed plate 14. The threaded rod 16 is threadedly connected to two threaded blocks 17 with reverse threads, so that the two threaded blocks 17 with reverse threads move in reverse directions along the threaded path of the threaded rod 16. Both side surfaces of the threaded block 17 are slidingly connected to the fixed plate 14 to prevent the threaded block 17 from rotating synchronously with the rotation of the threaded rod 16, thereby improving the functional structural stability of the device. An L-shaped limit plate 18 is fixedly connected to the bottom end of the threaded block 17.

The side of the limit plate 18 is rotatably connected with a rotating rod 19 through a groove, and the two rotating rods 19 are fixedly connected to the cutting blade 20 on the side. The two limit plates 18 are arranged to fit each other to achieve the position fixation of the two rotating rods 19 and the cutting blade 20, so that the two limit plates 18 can be separated to facilitate the convenient disassembly of the cutting blade 20, and prevent the cutting blade 20 from being damaged and reducing the cutting effect of the cardboard. The inner ring surface of one of the limit bearings 15 is fixedly connected with a T-shaped rotating block 21, and the side of the rotating block 21 is in rotational friction contact with the fixed plate 14.

Linear motor 1 8, linear motor 2 10, electric telescopic rod 11, and rotary motor 12 are all prior art. Their working principles, sizes, and models are irrelevant to the functions of the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

How it works

When using the carton processing and cutting device, the user places the cardboard at a designated position on the top of the processing table 1 and starts the electric telescopic rod 11. The moving end of the electric telescopic rod 11 drives the cutting blade 20 to cut the cardboard during the transmission process. The linear motor 1 8 and the linear motor 2 10 are started to realize the multi-position movement of the cutting blade 20, thereby improving the cutting flexibility of the cutting blade 20. At the same time, the rotating motor 12 is started to facilitate the control of the cutting direction of the cutting blade 20 through the output shaft of the rotating motor 12, thereby improving the structural stability of the device parts. In order to prevent the cutting device from cutting the cardboard and the cutting blade 20 from moving with great danger, the protective cover 6 is provided to provide a protective shielding effect, thereby improving the safety of the device, so that the protective cover 6 moves longitudinally along the path of the connecting rod 4, and the movable plate 5 is provided to improve the moving stability of the protective cover 6 while preventing the protective cover 6 from rotating, thereby improving the functional structural stability of the device.

The booster spring 7 is provided to provide an elastic thrust to prevent the protective cover 6 from shaking and reduce its protective effect, further improve the safety of the cutting device, and prevent the cutting blade 20 from being damaged during use. The protective cover 6 is pushed up to release the shielding effect of the protective cover 6, so that the rotating block 21 rotates. Driven by the rotating block 21, the two threaded blocks 17 with reverse threads move in opposite directions along the threaded path of the threaded rod 16. The two limit plates 18 are separated during the transmission process, so that the cutting blade 20 can be easily disassembled and the replaced cutting blade 20 can be moved to the specified position. By making the rotating block 21 rotate in the opposite direction, the two limit plates 18 can be moved centripetally during the transmission process, so that the rotating rod 19 fixedly connected to the two sides of the cutting blade 20 extends into the groove on the side of the limit plate 18, thereby fixing the position of the cutting blade 20 and making it easy to disassemble and install the cutting blade 20.
