[0007] Preferably, a rotating rod is rotatably installed inside the paper cutter body, and the rotating rod is fixedly connected to the paper cutter.
[0008] Preferably, a paper cutting blade is fixedly mounted on the outside of the paper cutting knife.
[0009] Preferably, a telescopic rod is fixedly mounted on the outside of the controller.
[0010] Preferably, the locking mechanism is a protective baffle fixedly mounted on the end of the telescopic rod.
[0011] Preferably, a handle is fixedly mounted on the end of the paper cutter.
[0012] Preferably, a support foot is fixedly mounted on the bottom of the paper cutter body.
[0013] The beneficial effect of the utility model is that, compared with the prior art, in the utility model, when a worker is about to be cut accidentally during paper cutting, the locking mechanism of the infrared sensor, the sensor, the controller and the protective baffle can immediately lock the paper cutting blade to prevent the paper cutting blade from continuing to cut paper downward, thereby playing a protective role and preventing the worker from being injured.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-4 The utility model provides a technical solution: a paper cutter with a protective function, including a paper cutter body 1, an infrared sensor lamp 3 is fixedly installed on the outside of the paper cutter body 1, and the infrared sensor lamp 3 is an E27 model. The infrared sensor lamp 3 is arranged on the side of the paper cutter 11 close to the paper cutter body 1, and is used to detect whether there is a worker performing a paper cutting operation under the cutting blade 5. A paper cutter 11 is arranged on the outside of the paper cutter body 1, and the paper cutter 11 is used to cut paper sheets. The material can be selected from the most common materials.
[0021] To further illustrate, a sensor 6 is fixedly installed on the outside of the paper cutter 11. The sensor 6 is a proximity sensor, model SN04-N. The function of the sensor 6 is to detect whether there is a worker's hand pushing a piece of paper under the blade.
[0022] A controller 10 is fixedly installed inside the paper cutter body 1. The model of the controller 10 is XL80IXL801. In order to receive the signals transmitted by the sensor 6 and the infrared sensor lamp 3 and make a protective emergency response, the infrared sensor lamp 3, the sensor 6 and the controller 10 are electrically connected. A locking mechanism is provided in the paper cutter body 1. The locking mechanism is controlled by the controller 10 to lock the blade to prevent the blade from continuing to move downward and injuring the worker.
[0023] To further explain, a telescopic rod 9 is fixedly installed on the outside of the controller 10. The telescopic rod 9 is used to extend and retract up and down to achieve the driving conditions of the controller 10. The locking mechanism is a protective baffle 8 fixedly installed at the end of the telescopic rod 9. The material of the protective baffle 8 can be selected from different types of materials according to personal cost to achieve a friction fixing effect.
[0024] When a worker puts his hand under the sensor 6, the infrared sensor 3 detects the signal emitted by the sensor 6, and after determining that it is a person, transmits the signal to the controller 10. The controller 10 makes a protective response and drives the telescopic rod 9 to move downward. The protective baffle 8 follows the telescopic rod 9 and continues to move downward, thereby fixing the rotating rod 4 and locking the paper cutter 11 to continue to move downward.
[0025] To further explain, a rotating rod 4 is rotatably installed inside the paper cutter body 1. The rotating rod 4 is used to enable the paper cutter 11 to rotate outside the paper cutter body 1 to achieve the purpose of cutting paper. The rotating rod 4 is fixedly connected to the paper cutter 11, and welding or other connection methods can also be used to achieve the fixing effect.
[0026] A paper cutting blade 5 is fixedly installed on the outside of the paper cutting knife 11. The material and size of the paper cutting blade are optional and can be selected according to different personal needs. The function of the paper cutting blade 5 is to cut paper pieces. A handle 7 is fixedly installed at the end of the cutting knife 11. The function of the handle 7 is to enable the worker to cut paper downwards better and prevent the skin from being rubbed. The handle can be made of fiber products such as rubber sponge.
[0027] Specifically, a support leg 2 is fixedly mounted on the bottom of the paper cutter body 1. The support leg 2 can be made of alloy, iron, rubber or plastic, and can play a supporting role.
[0028] Please refer to the following operation for specific use. When the worker is cutting, the sensor 6 is a proximity sensor and sends a signal to the controller 10. If the infrared sensor lamp 3 does not detect the receiving signal, it is determined to be a piece of paper, and the paper cutter 11 continues to move downward. If the infrared sensor lamp 3 receives the signal and detects it again to be the worker's hand or other parts, it will transmit a signal to the controller 10 together with the sensor 6. The controller 10 receives the signal and drives the telescopic rod 9 to move downward. The protective baffle 8 moves downward to fix the rotating rod 4, thereby locking the paper cutter 11 and playing a protective role.
