Description

Technical Field

[0001] The present invention relates to the field of power supply facilities, and particularly relates to a wire cutting machine. Background Art

[0002] During the power construction process, it is necessary to use a lot of wire cables of the same length. The wire cables are very thick. If cut manually, it is not only time-consuming and laborious, but also difficult to control the length. The lengths of the cut wires are uneven, and the efficiency is extremely low. Therefore, the applicant applied for an intelligent wire cutting machine on March 29, 2017, with the application number 2017101953431, which basically solved the above problems. However, in use, we found that the above intelligent wire cutting machine still has the following problems: when the conveying motor receives a stop signal and stops running, due to a certain inertia, the conveying motor still has a little rotation, and at the same time, the driving wheel also rotates a little to convey the wire cable forward. In this way, while conveying and cutting, the conveying process is affected by cutting and cannot convey forward, which will cause the wire cable to arch forward and affect the cutting quality; in addition, during the forward conveying process after cutting, the head end needs to be sent into the wire cable limiting cylinder. Summary of the Invention

[0003] In order to make up for the defects of the prior art, the present invention provides a wire cutting machine that is convenient to carry and store.

[0004] The present invention is realized by the following technical solutions:

[0005] A wire cutting machine includes a frame and a PLC control system. A conveying system and a cutting system are provided on the frame. The cutting system includes a cutting machine. The cutting machine is provided with a mounting plate. The mounting plate is connected to the output end of a cutting cylinder. A front sensor and a rear sensor are respectively provided on the frame in front of and behind the mounting plate. A conveying groove is provided on the frame. The conveying groove is located between the conveying system and the cutting system. It is characterized in that a discharging system is provided on the extension line of the conveying groove, wherein:

[0006] The conveying system includes a conveying cylinder. The output end of the conveying cylinder is provided with a sliding block. Two horizontally placed ratchets are provided on the sliding block. The rotation directions of the two ratchets are opposite. The sliding block is located on a slide rail. Two travel switches are installed on the slide rail or the frame. The sliding block is located between the two travel switches. The conveying groove is located in front of the slide rail;

[0013] The beneficial effects of the present invention are:

[0014] The present invention is provided with two ratchets controlled by a conveying cylinder. Due to the characteristic that the ratchet can only rotate in one direction, when the output shaft of the conveying cylinder outputs, the two ratchets act as clamps to drive the cable forward. When the output shaft retracts, under the combined action of the pressing cylinder, the ratchet rotates while the cable does not move. Since the cylinder can stop instantaneously, the inertia of the cable moving forward is avoided, so the defect that the cable arches forward when using a motor is solved; In addition, the front end of the discharging pipe is set as a discharging trough, and an auxiliary platform that can be lifted is hinged on the platform, which also makes it easy for the cable head to drill into the discharging pipe.

Specific embodiments

[0023] The accompanying drawings are specific embodiments of the present invention. As Figures 1 to 6 shown, this kind of cutting machine includes a frame 1 and a PLC control system, and the operation of the whole device is controlled by the PLC control system. A conveying system, a cutting system and a discharging system are sequentially installed on the frame 1, wherein:

[0024] The feeding system includes: a slide rail 2 is installed on the frame 1, there is a sliding block 3 on the slide rail 2, the sliding block 3 is fixed at the output end of the conveying cylinder 4, the conveying cylinder 4 is installed below the slide rail 2, there are two horizontally placed ratchet wheels 5 on the sliding block 3, the two ratchet wheels 5 are arranged front and back, that is, the center line connecting the two ratchet wheels 5 is perpendicular to the slide rail 2, and the rotation directions of the two ratchet wheels 5 are opposite. The circumferences of the two ratchet wheels 5 are concave inward to form an arc groove 51. The space formed between the two ratchet wheels 5 can just allow the cable to pass through and can form a certain extrusion on the cable. During the output process of the conveying cylinder 4, the cable is driven forward, and during the forward movement of the cable, the ratchet wheel 5 does not rotate. A travel switch is respectively installed on the frame 1 or the slide rail 2 in front of and behind the sliding block 3, and we name it the left travel switch 6 and the right travel switch 7. The positions of the two travel switches can be moved;

[0025] The cutting system includes a cutting machine 8, which is located on a front-back direction guide rail 9 on the frame 1. A mounting plate 10 is installed below the cutting machine 8, and the mounting plate 10 is connected to the output end of a cutting cylinder 11. The longitudinal direction of the cutting cylinder 11 is perpendicular to the advancing direction of the cutting cable. A front sensor 12 and a rear sensor 13 are respectively installed on the frame 1, and the front sensor 12 and the rear sensor 13 are arranged on both sides of the mounting plate 10. The mounting plate 10 moves back and forth between the front sensor 12 and the rear sensor 13; there is also a conveying trough 14 on the frame 1, and the conveying trough 14 is located in the advancing direction of the cable to be cut and between the conveying system and the cutting system, and its front end is preferably close to the cutting blade 801 of the cutting machine 8;

[0026] A pressing cylinder 15 with its output end facing down is installed between the slide rail 2 and the conveying trough 14. A pressing plate 16 is installed at the output end of the pressing cylinder 15. A platform 17 is installed on the frame 1 below the pressing plate 16. A groove 171 and an arc-shaped groove 51 are formed on the platform 17. The height of the groove 171 is the same as that of the conveying trough 14, which can make the cable located on the same straight line;

[0027] At the right end of the platform 17, that is, at the end facing the cutting system, an auxiliary platform 21 is hinged. A groove can also be formed on the auxiliary platform 21, or it is not necessary. There is a top-up micro cylinder 22 below the auxiliary platform 21. The stroke of the top-up micro cylinder 22 does not need to be too long, just a few millimeters to one centimeter. If there is no micro cylinder with such a small stroke, a lower travel switch 24 can be installed on the frame 1. A baffle 25 is installed on the output shaft of the top-up micro cylinder 22. When the output shaft of the top-up micro cylinder 22 extends and touches the lower travel switch 24, at this time, the output shaft of the top-up micro cylinder 22 will lift the right end of the auxiliary platform 21 by about 5 millimeters to 1 centimeter. When the output shaft of the top-up micro cylinder 22 retracts, the output shaft of the top-up micro cylinder 22 still abuts against the auxiliary platform 21 to play a supporting role; the output shaft of the top-up micro cylinder 22 only contacts the auxiliary platform 21 without connection. There is also a return spring 23 between the frame 1 and the auxiliary platform 21.

[0028] The discharging system includes a discharging pipe 18, which is at the same height and on the same straight line as the conveying trough 14, and is arranged on both sides of the cutting blade 801. The end of the discharging pipe 18 facing the cutting blade 801 is the cable inlet end, and the inlet end is a discharging trough 181, so that the cable can be easily inserted. The flare opening cannot be too large, just a little larger than the discharging pipe 18. An integrally connected discharging hopper 19 is provided with a top cover 20. The top cover 20 is hinged to the discharging hopper at the upper end, and the top cover 20 rests on the discharging hopper by its own gravity. The discharging hopper 19 tilts forward or backward.

[0029] Two travel switches, a conveying cylinder 4, a pressing cylinder 15, a cutting cylinder 11, a front sensor 12, a rear sensor 13, a lower travel switch 24 and an upper jacking micro-cylinder 22 are respectively connected to the PLC control system circuit.

[0030] The working process is as follows: First, adjust the distance between the two travel switches according to the length of the required cable segment. Manually pass the cable through the arc groove 51, the groove 171 and the conveying groove 14, and turn on the entire system. The conveying cylinder 4 extends, and the sliding block 3 slides on the slide rail 2. The two ratchets 5 drive the cable forward. When it reaches the right travel switch 7, under the control of the PLC control system, the conveying cylinder 4 stops running. The pressing cylinder 15 presses down to hold the cable. Then the conveying cylinder 4 retracts, and the ratchet 5 rotates. When the sliding block 3 touches the left travel switch 6, it stops running and waits for the next conveyance. At the same time, the cutting cylinder 11 starts, pushes the cutting machine 8 forward and cuts the cable. After cutting, the mounting plate 10 touches the front sensor 12 and transmits a signal to the PLC control system. The cutting cylinder 11 retracts. When the cutting cylinder 11 touches the rear sensor 13 during the retraction process, it transmits a signal to the PLC control system again. The PLC control system then transmits the signal to the pressing cylinder 15 and the conveying cylinder 4. The pressing cylinder 15 retracts and releases the pressing on the cable. The conveying cylinder 4 and the upper jacking micro-cylinder 22 start. The upper jacking micro-cylinder 22 jacks up the right end of the auxiliary platform 21. Along with the right end of the cable being jacked up, at the same time, the conveying cylinder 4 conveys the cable forward again. With the joint efforts of the conveying cylinder 4 and the upper jacking micro-cylinder 22, the right end of the cable crosses over the guide rail 9 and reaches above the discharge chute 181. After the baffle 25 touches the lower travel switch 24, the output shaft of the upper jacking micro-cylinder 22 retracts, and the auxiliary platform 21 returns to its original position under the combined action of its own weight and the return spring 23. The right end of the cable falls onto the discharge chute 181 and enters the discharge pipe 18 under the action of the conveying cylinder 4. At this time, part or all of the first cut cable segment is still in the discharge pipe 18. The cable conveyed again pushes the cable segment forward. After the cable segment completely breaks away from the discharge pipe 18, it falls from the discharge hopper 19. Repeating the above steps can obtain several cable segments.
