The mounting frame 6 is further provided with a driving part 9 used for driving the driving wheel 7 to rotate, the driving part 9 is set to be a motor, and the motor is connected with a power supply through an electric wire. When the driving part 9 is started, the driving wheel 7 rotates, and the cable is driven by the driving wheel 7 and the driven wheel 8 to move towards the movable knife 3 and the fixed knife 2, so that the automatic feeding of the cable is realized, and the operation of workers is facilitated.

The mounting rack 6 is rotatably connected with a driving wheel 10 with the circumference of 0.5 meter, the central axis of the driving wheel 10 is parallel to the central axis of the driving wheel 7, and the circumference of the driving wheel 10 is far larger than that of the driving wheel 7. The peripheral wall of the driving wheel 10 is fixedly sleeved with a driving gear ring 11, the peripheral wall of the driving wheel 7 is fixedly sleeved with a driving gear ring 12, and the driving gear ring 12 is meshed with the driving gear ring 11. The mounting rack 6 is provided with a first sliding groove 13 parallel to the cable conveying direction, a sliding strip 14 is embedded in the first sliding groove 13 in a sliding mode, the sliding strip 14 is provided with a plurality of first tooth grooves 15 which are distributed at equal intervals along the length direction of the sliding strip 14, and a first tooth block 16 is fixedly connected to the peripheral wall of the driving wheel 10. Each time the driving wheel 10 rotates one turn, the first tooth block 16 is inserted into one of the first tooth grooves 15 and pushes the slide 14 to advance one first tooth groove 15, so that the transmission distance of the cable is increased by 0.5 m. An elastic inserting strip 17 is fixedly connected to the mounting frame 6, the elastic inserting strip 17 can flexibly move between the first tooth grooves 15, and the purpose of the elastic inserting strip is to enable the displacement variation of the sliding strip 14 to be kept as the first tooth groove 15 of one lattice. In order to facilitate workers to observe how many first tooth sockets 15 are pushed out, a plurality of continuous digital marks 18 are further formed on the sliding strip 14, and the positions of the plurality of digital marks 18 correspond to the positions of the plurality of first tooth sockets 15 one by one.

A second sliding groove 19 parallel to the first sliding groove 13 is formed in the mounting frame 6, a sliding column 20 is embedded in the second sliding groove 19 in a sliding mode, one end of the sliding column 20 extends out of the mounting frame 6 and is fixedly connected with a baffle 21, and the baffle 21 is used for abutting against the end portion of the sliding strip 14 and limiting the movement of the sliding strip 14.

The spool 20 is also provided with a plurality of successive length values 23, the length values 23 being intended to indicate the distance of travel of the cable, also understood as the length of cut cable.

A cable cutting step: when the cable needs to be cut to a rated length, a worker needs to complete the following two preparation steps: firstly, a worker moves the baffle plate 21 to a specified position according to the cut length of the cable, and then locks the positions of the sliding column 20 and the baffle plate 21 through the locking piece 22; secondly, the end of the cable is close to the movable knife 3 and the fixed knife 2, and meanwhile, the first tooth groove 15 of the first grid is located right behind the first tooth block 16, as shown in the figure 1. When the two preparation steps are completed, the driving part 9 starts to drive the driving wheel 7 to rotate, and the cable continuously passes through the space between the movable knife 3 and the fixed knife 2 under the driving of the driving wheel 7 and the driven wheel 8. At the same time, the driving wheel 10 will rotate along with the driving wheel 7 under the meshing action of the driving toothed ring 12 and the driving toothed ring 11. When the driving wheel 10 is about to rotate one turn, the first tooth 16 on the driving wheel 10 will be inserted into the first tooth slot 15 of the first compartment, and at the same time, the sliding strip 14 is pushed to advance into the first tooth slot 15 of the first compartment, which represents that the transmission distance of the cable is increased by 0.5 meter, so that in this cycle, when the transmission distance of the cable is about to equal to the cut length of the cable, the first tooth 16 will be inserted into the corresponding first tooth slot 15 and drive the sliding strip 14 to abut against the baffle 21. At the moment, the transmission distance of the cable is equal to the cutting length of the cable, meanwhile, the driving wheel 7 stops rotating due to the resistance from the driving wheel 10, the clamp 5 clamps the cable, then the piston rod of the air cylinder 4 extends, and the cable can be successfully cut by the movable knife 3 and the fixed knife 2. If the cable needs to be conveyed again, a worker only needs to control the air cylinder 4 to enable the movable knife 3 to be retracted, and meanwhile, the clamping of the clamp holder 5 on the cable is cancelled.

Referring to fig. 1 and 2, the driving wheel 7 includes an inner wheel 71 coaxially fitted on the output shaft of the driving member 9, and an outer wheel 72 coaxially fitted on the inner wheel 71, the outer peripheral wall of the outer wheel 72 directly abuts against the cable, and the driving gear ring 12 is fixedly fitted on the outer wheel 72. The peripheral wall of the inner wheel 71 is fixedly sleeved with a ring of rubber rings 24 which are abutted with the inner wall of the outer wheel 72. When the baffle plate 21 successfully limits the slide bar 14, the outer wheel 72 and the driving gear ring 12 are limited by the transmission gear ring 11 and do not rotate any more, but the inner wheel 71 can still overcome the frictional resistance between the inner wheel and the outer wheel 72 and rotate, so that the situation that the driving part 9 is damaged due to overlarge load is avoided, and the service life of the driving part 9 is effectively prolonged.

A circle of thermal expansion strips 25 is embedded in the peripheral wall of the outer wheel 72, and the thermal expansion strips 25 are a circle of plastic film rings with hollow interiors. When the inner wheel 71 and the outer wheel 72 rotate relatively, heat is generated between the rubber ring 24 and the inner wall of the outer wheel 72, air in the thermal expansion strip 25 expands due to heating, the thermal expansion strip 25 expands and automatically abuts against the cable, and therefore stability and accuracy of the cable in the cutting process are improved. When the outer wheel 72 rotates again, the heat on the outer wheel 72 will gradually disappear, the thermal expansion strips 25 will return to the original state, and the outer wheel 72 can normally transmit the cable.

The implementation principle of the embodiment is as follows: the driving member 9 starts to drive the driving wheel 7 to rotate, and the cable is driven by the driving wheel 7 and the driven wheel 8 to continuously pass through the space between the movable knife 3 and the fixed knife 2. At the same time, the driving wheel 10 will rotate along with the driving wheel 7 under the meshing action of the driving toothed ring 12 and the driving toothed ring 11. When the driving wheel 10 is about to rotate one turn, the first tooth 16 on the driving wheel 10 will be inserted into the first tooth slot 15 of the first compartment, and at the same time, the sliding strip 14 is pushed to advance into the first tooth slot 15 of the first compartment, which represents that the transmission distance of the cable is increased by 0.5 meter, so that in this cycle, when the transmission distance of the cable is about to equal to the cut length of the cable, the first tooth 16 will be inserted into the corresponding first tooth slot 15 and drive the sliding strip 14 to abut against the baffle 21. At the moment, the transmission distance of the cable is equal to the cutting length of the cable, meanwhile, the driving wheel 7 stops rotating due to the resistance from the driving wheel 10, the clamp 5 clamps the cable, then the piston rod of the air cylinder 4 extends, and the cable can be successfully cut by the movable knife 3 and the fixed knife 2.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: equivalent changes made according to the structure, shape and principle of the invention shall be covered by the protection scope of the invention.
