technical field

The utility model relates to a paper cutter, which belongs to the technical field of printing machinery and equipment.

Background technique

With the development of social economy and the advancement of science and technology, the social demand for paper cutters continues to increase. Paper cutters are widely used in the printing and packaging industries. They are mainly used to cut paper of various specifications and thicknesses. To meet various needs of use. Most of the currently used paper cutters are complex in structure, large in size, expensive, take up a lot of space, and difficult to transport. They are not suitable for use in small rooms. There is an urgent need for a small and light paper cutter.

Contents of the invention

The purpose of the utility model is to provide a paper cutter.

The problem to be solved by the utility model is that the existing paper cutter has complicated structure, large volume and high price.

For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:

Paper cutter, including frame, motor, gear, limit switch, rack, guide groove, circular cutter, work table, forward rotation switch, reverse switch and positioning plate, the work table is fixed on the frame, and the rack is fixed On the working table, there is a travel switch at both ends of the rack, the gear and the rack are meshed, the motor is fixed on the positioning plate, the gear is fixed on the motor shaft, the round cutter is fixed on the gear through the shaft, and the round cutter Moving in the guide groove, the forward rotation switch and the reverse rotation switch are fixed on the working table, and the forward rotation switch and the reverse rotation switch are connected with the motor and the travel switch through wires.

The rack is provided with a guide edge to prevent the gear from moving; the gear can stop the motor when the gear touches the limit switch.

The utility model has the advantages of simple structure, convenient manufacture, lightness, compactness and low cost.

Description of drawings

Fig. 1 is a perspective view of the utility model paper cutter;

In the figure: 1. Frame 2. Motor 3. Gear 4. Travel switch 5. Rack 6. Guide groove 7. Round cutter 8. Working surface 9. Forward rotation switch 10. Reverse rotation switch 11. Positioning plate.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in the figure, the paper cutter includes a frame 1, a motor 2, a gear 3, a travel switch 4, a rack 5, a guide groove 6, a circular cutter 7, a working surface 8, a forward rotation switch 9, and a reverse rotation switch 10 and the positioning plate 11, the working surface 8 is fixed on the frame 1, the rack 5 is fixed on the working surface 8, and a travel switch 4 is respectively provided at both ends of the rack 5. When the gear 3 touches the travel switch 4, the motor 2 stops rotating, and the circular cutter 7 also stops cutting, so that the circular cutter 7 travels in one direction, the gear 3 meshes with the rack 5, and the motor 2 is fixed on the positioning plate 11 to prevent the motor 2 from turning over when it is working; The gear 3 is fixed on the shaft of the motor 2, the circular cutter 7 is fixed on the gear 3 through the shaft, the circular cutter 7 moves in the guide groove 6, the rotation of the motor 2 drives the gear 3 to rotate, and the rotation of the gear 3 makes the circular cutter 7 move in the guide groove 6. The circular cutter 7 moves freely while rotating, so that it can cut the paper normally. The forward rotation switch 9 and the reverse rotation switch 10 are fixed on the work table 8. The forward rotation switch 9 and the reverse rotation switch 10 communicate with each other through wires. The motor 2 and the travel switch 4 are connected. When the forward rotation switch 9 is pressed, the circular cutter 7 moves in a certain direction along the guide groove 6, and stops after meeting the travel switch 4. When the reverse rotation switch 10 is pressed, the circular cutter 7 moves in the opposite direction. Movement, stop after encountering limit switch 4.

The rack 5 is provided with a leading edge to prevent the gear 3 from moving. the

The usage method of the utility model: switch on the power supply, place the paper to be cut on the work surface 8 and close to the circular cutter 7, press the forward rotation switch 9, the motor 2 starts to rotate, and the rotation of the motor 2 drives the gear 3 to rotate, and the gear 3 The rotation drives the circular cutter 7 to rotate and move in the guide groove 6. When the circular cutter 7 moves, the paper is cut. After the cutting is completed, when the gear 3 touches the travel switch 4, the motor 2 stops rotating, and the circular cutter 7 stops working. , to complete the cutting work. When needing to work next time, the paper is placed on the work surface 8 equally, and the reverse switch 10 is pressed to make the circular cutter 7 go back and start cutting, and stop after running into the travel switch 4.
