[0040] Please refer to Figures 1-4 , the present utility model provides a wire cutting machine, which includes:

[0041] A machine table 1;

[0042] A feeding assembly, which includes two brackets 2 arranged on the machine table 1. A feeding roller 3 is rotatably connected between the two brackets 2. The feeding roller 3 is connected to a motor through a belt, and the motor is arranged inside the machine table 1;

[0043] Cutting device 4, the cutting device 4 is arranged at one end of the feeding roller 3;

[0044] Guide assembly 5, which is arranged at the other end of the feeding roller 3. The guide assembly 5 includes a plurality of guide blocks 51 and a plurality of pressing plates 52. The guide blocks 51 are arranged along the direction of the machine table 1. The guide blocks 51 are connected to the machine table 1 through the pressing plates 52. A number of rolling members 6 are respectively arranged on both sides of the guide blocks 51.

[0045] In one embodiment, as Figure 3 , the rolling member 6 is a spherical ball. The spherical ball protrudes from the surface of the guide block 51 and is rotatably connected to the guide block 51. The spherical balls cover the side surface of the guide block, which can reduce friction.

[0046] In another embodiment, as Figure 4 , the rolling member 6 is a guide roller. The guide roller is rotatably connected to the guide block 51. A plurality of guide rollers are arranged along the length direction of the guide block.

[0047] Mounting holes are provided on the bracket 2. A pressure regulating bolt 7 is arranged in the mounting holes. The pressure regulating bolt 7 passes through the mounting holes and is connected to the feeding roller 3. By rotating the pressure regulating bolt, the position of the pressure regulating bolt can be adjusted up and down, so as to adjust the position of the feeding roller, achieve the purpose of adjusting the pressure, and facilitate feeding. The feeding roller is a driving roller. The feeding roller is driven by a stepping motor. The microcomputer controls the rotating speeds of the motor and the feeding roller to achieve stepless speed adjustment of any length of the wire.

[0048] The pressing plate 52 is connected to the machine table 1 by screws. The pressing plate 52 is provided with an adjusting long hole 8. A pressing screw 9 is arranged at the position corresponding to the guide block 51 in the adjusting long hole 8. The pressing screw 9 is connected to the guide block 51. By loosening the pressing screw, the guide block can be moved, so as to adjust the distance between the guide blocks to adapt to the cutting of wires of different lengths.

[0049] A first guide roller 10 is arranged at one end of the machine table 1 away from the cutting device 4. It is convenient for wire feeding and reduces the collision between the wire and the machine table.

[0050] A display screen 11, an operation key 12 and a switch button 13 are also arranged on the machine table 1.

[0051] A protective film is arranged on the display screen 11 and the operation key 12. Scales are arranged on the protective film. The protective film can prevent the display screen from being scratched and prevent the values on the operation key from being worn. The scales can facilitate the measurement of the cut wire.

[0052] Working principle: When cutting a wire, the wire passes through the upper surface of the first guiding roller and enters the space between the guiding blocks, then passes through the feeding roller. The cutting speed and cutting length are set through the display screen and operation buttons. After pressing the switch button, the cutting machine starts to work, and the cutting device begins to cut. By respectively arranging rolling elements on both sides of the guiding blocks, when the wire passes through the transmission channel formed in the middle of the guiding blocks, the wire contacts the rolling elements connected movably, which can reduce the friction between the wire and the guiding blocks, facilitate the transmission of the wire, and is not likely to scrape against the guiding blocks, reducing the probability of wire scratches.

[0053] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
