[0026] As Figures 1 to 7 shown, a paper cutter with a protection function includes a base 1. A workbench 2 is fixedly installed on the top of the base 1. An installation frame 3 is fixedly installed on the top of the workbench 2. A cutting mechanism 4 for cutting paper is arranged inside the installation frame 3. A foot pedal 5 for controlling the operation of the cutting mechanism 4 is arranged at the bottom of the base 1. A protective cover 6 with an L-shaped structure is arranged at the front side of the base 1. A driving component 7 for driving the protective cover 6 to lift is arranged at the right side of the base 1. An infrared sensor 8 is arranged on the top of the workbench 2. A lifting component 9 for driving the infrared sensor 8 to lift is arranged on the top of the workbench 2. A moving component 10 for driving the lifting component 9 to move back and forth is arranged inside the installation frame 3. A limiting component 11 for limiting the foot pedal 5 is arranged at the front side of the base 1. It should be noted that when the paper is placed on the top of the workbench 2, the protective cover 6 will be in the position closest to the foot pedal 5. When the paper is placed and the foot pedal 5 needs to be stepped on to make the cutting mechanism 4 perform cutting, first control the driving component 7 to lift the protective cover 6 by a certain height to expose the foot pedal 5 for convenient stepping. And before cutting the paper, it is necessary to further adjust the moving component 10 to move the lifting component 9 to a suitable position. The infrared sensor 8 will continuously lift and lower under the drive of the lifting component 9. By the infrared sensor 8 sensing whether there is an object above the front side of the top of the workbench 2, the purpose is to determine whether the staff's hand is withdrawn. When the infrared sensor 8 does not detect an object, the limiting component 11 can immediately release the restriction on the foot pedal 5, facilitating the staff to step on the foot pedal 5, thereby avoiding the situation of accidental touch of the foot pedal 5 and ensuring safe production.

[0027] As Figures 1 to 5As shown, the driving component 7 includes a square plate 701. The square plate 701 is fixedly installed on the right side wall surface of the base 1. A servo motor 702 is fixedly installed at the bottom of the square plate 701. The output end of the servo motor 702 is fixedly connected to a lead screw 703. A movable block 704 is threadedly connected to the lead screw 703. A chute 705 is provided on the right side wall surface of the base 1. A slider 706 that is movably installed inside the chute 705 is fixedly installed on the left wall surface of the movable block 704. An L-shaped rod 707 is fixedly installed on the front wall surface of the movable block 704. The other end of the L-shaped rod 707 is fixedly connected to the protective cover 6. A button 710 for controlling the operating state of the servo motor 702 is provided on the top of the base 1. It should be noted that after the servo motor 702 is started, it can drive the lead screw 703 to rotate reciprocally, so that the movable block 704, the slider 706, the L-shaped rod 707, and the protective cover 6 are lifted and lowered synchronously. After the paper is placed on the top of the operating table 2, the operator only needs to press the button 710 to make the protective cover 6 complete a reciprocating motion.

[0028] As Figures 1 to 5 shown, the driving component 7 further includes a limiting groove 708. The limiting groove 708 is provided on the front wall surface of the base 1. A limiting block 709 that is movably installed inside the limiting groove 708 is fixedly connected to the protective cover 6. It should be noted that when the protective cover 6 moves up and down, it can drive the limiting block 709 to slide up and down inside the limiting groove 708, restricting the movement track of the protective cover 6.

[0029] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 shown, the lifting component 9 includes an L-shaped frame 901. The L-shaped frame 901 is provided on the top of the operating table 2. A servo motor 902 is fixedly installed on the top of the L-shaped frame 901. The output end of the servo motor 902 penetrates the top of the L-shaped frame 901 and is fixedly connected to a threaded rod 903. A lifting block 904 is threadedly connected to the threaded rod 903. A positioning groove 905 is provided on the inner side wall surface of the L-shaped frame 901. A positioning block 906 that is movably installed inside the positioning groove 905 is fixedly installed on the side wall surface of the lifting block 904. The lifting block 904 is fixedly connected to the infrared sensor 8. It should be noted that after the servo motor 902 is started, it can drive the threaded rod 903 to rotate reciprocally. The reciprocating rotation of the threaded rod 903 will cause the lifting block 904, the positioning block 906, and the infrared sensor 8 to move up and down. The up and down movement of the infrared sensor 8 can detect whether there is an object above the front side of the top of the operating table 2.

[0030] As Figure 4 、 Figure 6As shown, the moving component 10 includes a groove 1001. A groove 1001 is formed on the front wall surface of the mounting frame 3. A telescopic rod 1002 is movably installed inside the groove 1001. A threaded hole 1003 communicating with the inside of the groove 1001 is formed on the left wall surface of the mounting frame 3. A bolt 1004 is threadedly connected inside the threaded hole 1003. An L-shaped frame 901 is fixedly installed on the top of the groove 1001. It should be noted that pulling the telescopic rod 1002 can synchronously drive the L-shaped frame 901 to move back and forth. Rotating the bolt 1004 can fix the position of the telescopic rod 1002. The L-shaped frame 901 can move to an appropriate position back and forth according to the paper size.

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, the limiting component 11 includes a rectangular block 1101. Two rectangular blocks 1101 are fixedly installed on the front wall surface of the base 1. A bidirectional screw 1103 is movably installed between the two rectangular blocks 1101. A servo motor three 1102 for driving the bidirectional screw 1103 to rotate is fixedly installed on the side wall surface of the right rectangular block 1101 (in this technical solution, the infrared sensor 8 and the servo motor three 1102 are connected by a wireless signal. The infrared sensor 8 can send a signal to start or stop the servo motor three 1102). Moving blocks 1104 are respectively threadedly connected to both ends of the bidirectional screw 1103. A constraint groove 1105 is formed on the front wall surface of the base 1. A constraint block 1106 movably installed inside the constraint groove 1105 is fixedly installed on the rear wall surface of each moving block 1104. A limiting frame 1107 is fixedly installed on the bottom of each moving block 1104. The two limiting frames 1107 are mirror-symmetrically distributed. It should be noted that when the servo motor three 1102 is started, the threaded hole 1003 can rotate reciprocally, so that the two bolts 1004 move away from or close to each other. The movement of each moving block 1104 drives the connected constraint block 1106 and limiting frame 1107 to move synchronously. When the two limiting frames 1107 are both located at the bottom of the foot pedal 5, it can prevent the foot pedal 5 from being accidentally stepped on. When the two limiting frames 1107 move away from each other, the restriction on the foot pedal 5 can be released.

[0032] In summary:

[0033] When the paper is placed on the top of the operating table 2, the protective cover 6 will be in the position closest to the foot pedal 5. When it is necessary to step on the foot pedal 5 to make the cutting mechanism 4 perform slitting after the paper placement is completed, first control the driving component 7 to raise the protective cover 6 by a certain height to expose the foot pedal 5 for convenient stepping. And before slitting the paper, it is necessary to further adjust the moving component 10 to move the lifting component 9 to a suitable position. The infrared sensor 8 will continuously rise and fall driven by the lifting component 9. By the infrared sensor 8 sensing whether there is an object above the front side of the top of the operating table 2, the purpose is to determine whether the staff's hand is withdrawn. When the infrared sensor 8 does not detect an object, the limiting component 11 can immediately release the restriction on the foot pedal 5, facilitating the staff to step on the foot pedal 5, thereby avoiding the situation that the foot pedal 5 is accidentally touched and ensuring safe production.
