During the cutting process, since the taken-out cable is in a bent state, the end of the cable cutting is prone to an uneven cross-section. Moreover, the length of the cut cable often deviates due to the bending. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.
[0020] Please refer toFigures 1-4 , a cable cutting device, comprising a cutting table 1, a fixing frame 2 is fixedly arranged on the cutting table 1, a lifting seat 3 is installed on the fixing frame 2 through an electric telescopic cylinder 4, a cutting module 5 is installed on the lifting seat 3, a straightening mechanism is further arranged on the cutting table 1 on one side of the fixing frame 2, and a fixing mechanism is arranged on the cutting table 1 below the cutting module 5;
[0021] The straightening mechanism comprises a pair of limiting members 6 symmetrically arranged on the cutting table 1. The limiting members 6 are in an "L" shape. The two limiting members 6 are movably arranged on the cutting table 1 through slide rails and are driven by a first air cylinder 7 arranged on the cutting table 1;
[0022] The fixing mechanism comprises a pair of U-shaped plates 8 fixedly installed on the cutting table 1, a pair of limiting plates 9 symmetrically and movably installed in the U-shaped plates 8, and a driving assembly for driving the two limiting plates 9 to move relatively. Among them, a gap for the cutting blade to shuttle through is reserved between the two U-shaped plates 8. By arranging the straightening mechanism, when the cable is taken out and placed between the two limiting members 6 on the cutting table 1, the first air cylinder 7 drives the two limiting members 6 to approach relatively, and the straightening of the cable can be realized. When the straightened cable is cut, not only the flatness of the cable cutting port is ensured, but also the accuracy of the cable cutting length is improved. The setting of the fixing mechanism can fix the cutting position when the cutting module 5 cuts the cable, avoid the situation of wire breakage during the cable cutting process, and further improve the flatness of the cable cutting.
[0023] Specifically, the driving assembly comprises a pair of driving units symmetrically arranged in the fixing frame 2. The driving unit comprises a support plate 10, a first push rod 11, a second push rod 12, a cross plate 15 and a connecting rod 14. The support plate 10 is fixedly installed on the inner wall of the fixing frame 2. The first push rod 11 and the second push rod 12 are respectively movably installed on the support plate 10 and the U-shaped plate 8 through springs 13, and the first push rod 11 is connected to the second push rod 12 through the connecting rod 14. Among them, both ends of the connecting rod 14 are hinged to the first push rod 11 and the second push rod 12 respectively. A cross plate 15 is installed at the top end of the first push rod 11. The limiting plate 9 is fixedly installed at the end of the second push rod 12. The setting of this driving assembly does not require an additional driving electrical component to drive the two limiting plates 9 to move relatively, reducing the production cost. Specifically, during the process of the electric telescopic cylinder 4 driving the lifting seat 3 to move downward, the lifting seat 3 drives the cross plate 15 and the first push rod 11 to move downward at the same time. Under the transmission of the connecting rod 14, the second push rods 12 on both sides of the U-shaped plate 8 approach relatively, and the two limiting plates 9 fix the cable.
[0024] In addition, a compensation plate 16 is further installed on the side surface of the limit plate 9 through an elastic member 17. The arrangement of the elastic member 17 and the compensation plate 16 can not only ensure the normal descent of the cutting module 5, but also realize the fixation of cables with different diameters, further improving the practicability of the device.
[0025] Furthermore, a feeding mechanism is further arranged on the cutting table 1 on one side of the straightening mechanism. The feeding mechanism includes an arched frame 18 fixedly arranged on the cutting table 1 and a pair of conveying rollers 19 rotatably arranged in the arched frame 18. One of the conveying rollers 19 is driven by a motor arranged on the cutting table 1, and the other conveying roller 19 is movably arranged in the arched frame 18 through a roller sleeve 20. A second air cylinder 21 for driving the roller sleeve 20 to move up and down is further arranged on the arched frame 18. The arrangement of the feeding mechanism can realize the automatic feeding of the cable, eliminating the need for manual loading and unloading, reducing the labor intensity of workers, and improving the cutting efficiency of the cable.
