Description

Technical Field

[0001] The present invention relates to the technical field of cable outer sheath stripping, in particular to a cable outer sheath stripping machine. Background Art

[0002] Armored cables generally include a core, a steel armor layer, and an outer sheath (such as Figure 4 ), the steel armor layer is generally wrapped with steel tape to protect the cable from damage by external mechanical forces.

[0003] However, when inspecting the cable outer sheath, it is necessary to cut the outer sheath longitudinally. At present, the outer sheath is generally cut longitudinally by using a conveying mechanism to transport the cable to a flat cutter, and the outer sheath is cut longitudinally by using the relative movement between two symmetrically arranged flat cutters and the cable. Although this method can achieve longitudinal cutting of the outer sheath, it will not only affect the overall cutting efficiency of the cable, but also cause burrs and cracks on the outer sheath, affecting the quality of the cut surface of the outer sheath.

[0004] In addition, due to the different thicknesses of cables, the thickness of their outer sheaths is also different. The stripping equipment currently on the market cannot accurately cut the outer sheath and often cuts the steel armor layer during cutting. However, since the material of the steel armor layer is harder, it causes greater damage to the tool. Therefore, the stripping equipment currently on the market generally requires manual repeated adjustment of the distance between the two tools before cutting to adapt to the cutting of the outer sheath, which is not only troublesome but also reduces the stripping efficiency of the outer sheath.

[0082] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0083] See also Figure 1 - Fig.14The present embodiment provides a loading roller conveyor 100, a peeling machine box 200, a discharging roller conveyor 300 and a controller 201 arranged on the peeling machine box 200. The peeling machine box 200 is provided with a clamping conveying mechanism 500 and a peeling mechanism 400. The cable 600 to be peeled is put from the loading roller conveyor 100, and is taken out from the discharging roller conveyor 300 after passing through the conveying mechanism and the peeling mechanism 400 in sequence; the peeling mechanism 400 includes a mounting plate 410 installed in the peeling machine box 200, and two supporting plates are installed on the side of the mounting plate 410. The knife holder 420, and the two supporting knife holders 420 are respectively located above and below the cable 600 to be cut; two circular cutters 430 are rotatably connected to the supporting knife holder 420, and when stripping, the two circular cutters 430 cut the outer sheath 601 of the cable 600 from the bottom and top of the cable 600 respectively. The circular cutter 430 can more conveniently cut into the cable 600 from the peripheral side of the cable 600, and as the clamping and conveying mechanism 500 conveys the cable 600, the circular cutter 430 cuts the outer sheath 601 in a rolling cutting manner;

[0084] The stripping mechanism 400 includes a diameter adjustment component 440, which is mainly used to adjust the distance between the two support knife racks 420 to adapt to the longitudinal cutting of cables 600 of different diameters. The diameter adjustment component 440 specifically adjusts the distance between the two support knife racks 420 so that the positions of the two circular cutting knives 430 with respect to the cable 600 are symmetrical to each other;

[0085] The stripping mechanism 400 also includes a thickness adjustment component 450, which is used to control the two circular cutters 430 to synchronously cut into the outer sheath 601 from the top and bottom of the cable 600 until the two cutters just contact the steel armor layer 602 at the same time; the thickness adjustment component 450 includes a cutting depth detection mechanism 452 for detecting whether the circular cutter 430 contacts the steel armor layer 602 and a cutting depth control mechanism 451 for controlling the two circular cutters 430 to synchronously feed toward each other from the upper and lower sides of the cable 600. When the circular cutter 430 contacts the steel armor layer 602, the cutting depth control mechanism 451 immediately controls the two circular cutters 430 to stop feeding toward each other.

[0086] The following is a further introduction in combination with specific usage scenarios. When stripping the outer sheath 601 of the cable 600, the cable 600 to be cut is first placed on the loading roller line 100, and the cable 600 is sent from the loading roller line 100 to the clamping and conveying mechanism, the cable 600 is clamped by the clamping and conveying mechanism, and the cable 600 is conveyed to the stripping mechanism 400. At the peeling mechanism 400, the diameter adjustment component 440 is first used to adjust the position of the support knife holder 420 so that the two circular cutters 430 are symmetrical about the cable 600. When the positions of the two circular cutters 430 about the cable 600 are symmetrical, the cutting depth control mechanism 451 is used to control the two circular cutters 430 to feed synchronously toward the center of the cable 600 and then cut the outer sheath 601 until the cutting depth detection mechanism 452 detects that the circular cutter 430 is just in contact with the steel armor layer 602. The cutting depth detection mechanism 452 immediately transmits a signal to the controller 201, and the controller 201 timely controls the cutting depth control mechanism 451 stops running, so that the positions of the two circular cutters 430 are always in contact with the steel armor layer 602, and then the clamping and conveying mechanism 500 continues to convey the cable 600 to the stripping mechanism 400, so that the two circular cutters 430 can be used to cut the outer sheath 601 of the cable 600, and it is guaranteed that the steel armor layer 602 will not be cut, thereby ensuring the service life of the tool, and the cutting of the outer sheath 601 of the cable 600 is more automated, and can adapt to the longitudinal cutting of the outer sheath 601 of the cable 600 with different diameters and thicknesses, thereby improving the convenience of the outer sheath 601 stripping work and also improving the outer sheath 601 stripping work efficiency.

[0087] Specifically, for how to adjust the spacing between the support blade holders 420 so that the two circular cutting blades 430 are symmetrical about the cable 600, refer to Figure 5-Figure 7The diameter adjustment assembly 440 of the present application includes a fixed frame 441 installed on the side of the mounting plate 410, and two guide rails 442 are also vertically fixed on the side of the mounting plate 410. The movable frame 443 is slidably connected to the two guide rails 442. A set of support wheels 444 are rotatably connected to the fixed frame 441 and the movable frame 443. The two sets of support wheels 444 are mainly used for auxiliary fixing and auxiliary transportation of the cable 600 to ensure that the position of the cable 600 near the circular cutter 430 during the cutting process is more stable; two first screw rods 445 are rotatably connected to the mounting plate 410, and the first screw rods 445 are rotatably connected to the mounting plate 410, and the first screw rods 445 are rotatably connected to the mounting plate 410. The screw rod 445 is threadedly connected to the movable frame 443, and a first motor 446 for driving the two first screw rods 445 to rotate synchronously is installed on the side of the mounting plate 410; the two supporting tool holders 420 are respectively installed on the fixed frame 441 and the movable frame 443. In addition, distance measuring sensors 447 are installed on the fixed frame 441 and the movable frame 443. The distance measuring sensor 447 on the fixed frame 441 is used to detect the distance from the fixed frame 441 to the bottom of the cable 600, and the distance measuring sensor 447 on the movable frame 443 is used to detect the distance from the movable frame 443 to the cable 600.

[0088] In combination with the specific usage scenario, first of all, it should be explained here that the support of the cable 600 by the clamping and conveying mechanism 500 should be horizontal, and should be conveyed horizontally to the support wheel 444 of the fixed frame 441. Therefore, when assembling the peeling machine, it should be ensured that the wheel surface of the conveying wheel or the roller surface of the conveying roller at the bottom of the clamping and conveying mechanism 500 should be flush with the wheel surface of the support wheel 444. When the head end of the cable 600 is conveyed to the support wheel 444 of the fixed frame 441 by the clamping conveying mechanism, the distance sensor 447 on the fixed frame 441 will detect the distance between the bottom of the cable 600 and the fixed frame 441, and the distance sensor 447 on the movable frame 443 will also detect the distance between the movable frame 443 and the top of the cable 600; then the first motor 446 is driven to drive the first screw rod 445 to rotate, and further drive the movable frame 443 to move downward as a whole. When the detection data of the two distance sensors 447 are the same, the distance sensor 447 transmits the data information to the controller 201, and the controller 201 controls the first motor 446 to stop. At this time, the purpose of making the two circular cutters 430 symmetrical about the cable 600 is achieved.

[0089] Further, see Figure 5-Figure 8As a specific implementation of the embodiment of the present application, the cutting depth control mechanism 451 includes two sleeves 4511 rotatably connected to the fixed frame 441 and the movable frame 443 respectively. Specifically, a mounting through hole is opened in the middle of the fixed frame 441 and the middle of the movable frame 443, and a bearing 700 is installed in the through hole. The sleeve 4511 is coaxially fixed in the inner ring of the bearing 700; the two sleeves 4511 are threadedly connected with a second screw rod 4512, and the second screw rod 4512 is fixedly connected to the support tool holder 420. An optical axis 4513 is also fixed on the two support tool holders 420. The two optical axes 4513 are respectively slidably connected to the fixed frame 441 and the movable frame 443. A driving device 4514 for driving the two sleeves 4511 to rotate synchronously is also installed on the mounting plate 410.

[0090] In combination with specific usage scenarios, after the height of the movable frame 443 is adjusted by using the diameter adjustment component 440, the two circular cutters are made symmetrical about the cable 600, and then the driving device 4514 is started. The two sleeves 4511 are controlled to rotate synchronously by the driving device 4514. Since the sleeve 4511 is threadedly connected to the second screw rod 4512, and the cooperation between the second screw rod 4512 and the optical axis 4513 limits the rotation of the support tool holder 420, when the driving device 4514 is used to control the rotation of the two sleeves 4511, the spiral cooperation between the sleeve 4511 and the second screw rod 4512 can control the lifting and lowering of the support tool holder 420, specifically, the lifting of the support tool holder 420 on the fixed frame 441 and the lowering of the support tool holder 420 on the movable frame 443 can be controlled, so that the cable 600 can be cut synchronously from the upper and lower sides toward the core 603.

[0091] Further, see Figure 8The driving device 4514 includes a second motor 45141 fixed to the side of the mounting plate 410, and the second motor 45141 is electrically connected to the controller 201. The shaft end of the second motor 45141 is connected to a driving rod 45142 through a coupling 45148, and a synchronous pin groove 45143 is provided on the peripheral side of the driving rod 45142; a mounting frame 45144 is fixed to the movable frame 443, and a first gear 45145 is rotatably connected in the mounting frame 45144. The mounting frame 45144 is mainly used to ensure the consistency of the position of the first gear 45145 and the movable frame 443. Here, in order to ensure the stability of the position of the first gear 45145 relative to the movable frame 443, the present application provides annular limiting grooves on the two axial sides of the first gear 45145, and also provides annular limiting grooves on the mounting frame 45144, and A ball 451441 is loaded between a gear 45145 and a limiting groove of the mounting frame 45144; the mounting frame 45144 is arranged to be split into an upper and a lower part, and the two parts are connected by bolts, so that the assembly between the mounting frame 45144, the first gear 45145 and the ball 451441 can be facilitated; in addition, the first gear 45145 is coaxial with the driving rod 45142, and a pin block is fixed in the inner circle of the first gear 45145, and the pin block is slidably connected in the synchronization pin groove 45143; a second gear 45146 is also coaxially fixed to the driving rod 45142, and a third gear 45147 is coaxially fixed to both sleeves 4511, the third gear 45147 located on the movable frame 443 is meshedly connected to the first gear 45145, and the third gear 45147 located on the fixed frame 441 is meshedly connected to the second gear 45146.

[0092] In combination with a specific usage scenario, when the diameter adjustment component 440 is used to adjust the position of the movable frame 443, the first gear 45145 on the mounting frame 45144 will move downward along the axis of the driving rod 45142. During the downward movement, the pin block fixed in the first gear 45145 is still stuck in the synchronous pin groove 45143. When the positions of the two circular cutters 430 are symmetrical about the cable 600, the second motor 45141 drives the driving rod 45142 to rotate, which in turn drives the first gear 45145 and the second gear 45146 to rotate synchronously, further The engagement of the third gear 45147 on the fixed frame 441 with the first gear 45145 drives the sleeve 4511 on the movable frame 443 to rotate, so that the circular cutter 430 on the movable frame 443 feeds toward the center of the cable 600, and then cuts the outer sheath 601 from the top of the cable 600; and the engagement of the third gear 45147 on the fixed frame 441 with the second gear 45146 drives the sleeve 4511 on the fixed frame 441 to rotate, thereby controlling the circular cutter 430 on the fixed frame 441 to feed toward the center of the cable 600 and then cut the outer sheath 601 from the bottom of the cable 600.

[0093] It should be noted here that: the two second screw rods 4512 can actually be driven by two motors, but this requires increasing the number of motors used, and requires synchronous control of the forward and reverse rotation of the two motors to ensure the synchronization of the motor rotation, which requires more precise and strict control and increases costs.

[0094] Reference Figure 5 , Fig. 9 and Fig.10 As a specific implementation of the embodiment of the present application, the cutting depth detection mechanism 452 includes a power supply, a wire 4521 is arranged in the stripping machine box 200, and the wire 4521 is electrically connected to the circular cutter 430 installed on the fixing frame 441. It should be noted here that the material of the circular cutter 430 should be a conductive material, such as cemented carbide. The wire 4521 is electrically connected to the wire clamp 4522, and the wire clamp 4522 is used to clamp the steel armor layer 602 of the cable 600; a current sensor 4523 is installed on the mounting plate 410, and the current sensor 4523 is electrically connected to the controller 201; when the circular cutter 430 contacts the steel armor layer 602, the power supply, the current sensor 4523, the wire 4521, the wire clamp, the circular cutter 430, and the steel armor layer 602 of the cable are connected to form a path, and the current sensor 4523 transmits the signal to the controller 201.

[0095] In combination with specific usage scenarios, before stripping, the steel armor layer 602 at the end of the cable 600 is clamped with a wire clamp 4522 (here the end of the cable 600 that first enters the stripping chassis 200 is the first end). When the two circular cutters 430 are controlled by the cutting depth control mechanism 451 to cut into the outer sheath 601, the cutting depth increases accordingly. When the circular cutter 430 on the fixing frame 441 just contacts the steel armor layer 602, the power supply, the current sensor 4523, the wire 4521, the wire clamp, the circular cutter 430, and the steel armor layer 602 are connected to form a path, and the current sensor 4523 collects the change in current (proving that the circular cutter 430 on the fixing frame 441 just contacts the steel armor layer 602). Then the current sensor 4523 transmits the signal data to the controller 201, and the controller 201 promptly controls the second motor 45141 of the cutting depth control mechanism 451 to stop running, so that the two circular cutters 430 stop going deeper. After that, it is only necessary to control the cable 600 to be continuously transported to the circular cutter 430 through the clamping and conveying mechanism to achieve the longitudinal cutting of the outer sheath 601 of the cable 600. It should be explained again here that when the circular cutter 430 on the fixed frame 441 just contacts the steel armor layer 602, the circular cutter 430 installed on the movable frame 443 should also be in a state of synchronously contacting the steel armor layer 602.

[0096] Furthermore, the wire 4521 used in the present application is a metal wire without an insulating sheath. Fig. 9 and Fig.10 A sliding plate 4524 is installed on the mounting plate 410, and one end of the sliding plate 4524 is at the circular cutter 430. A sliding groove 4526 in a closed ring shape is opened on the sliding plate 4524. The wire 4521 is fixed in the sliding groove 4526. A conductive brush 4525 is slidably connected in the sliding groove 4526, and the conductive brush 4525 is always electrically connected to the wire 4521, and the wire clamp 4522 is electrically connected to the conductive brush 4525; in addition, the sliding groove 4526 of the present application is in a closed ring shape as a whole; there are also two conductive brushes 4525 used, each of which is installed with a wire clamp 4522, and the positions of the two conductive brushes 4525 are symmetrically distributed about the center of the sliding groove 4526; a pulling rope 4527 is fixed between the two conductive brushes 4525.

[0097] Combined with the specific usage scenario, during the cutting process of the cable 600, as the clamping and conveying mechanism 500 conveys the cable 600 little by little to the stripping mechanism 400, the circuit constructed by the power supply, current sensor 4523, wire 4521, wire clamp, circular cutter 430, and steel armor layer 602 is continuously turned on during this process, and as the stripping work of the cable 600 is gradually coming to an end, the wire clamp 4522 clamping the steel armor layer 602 will also move along the sliding groove 4526 during this process; when the cutting of the cable 600 is completed, as the clamping and conveying mechanism 500 continues to convey the cable 600, the sliding groove 4526 cooperates with the Due to the position constraint of the conductive brush 4525, the wire clamp 4522 will be forced to separate from the steel armor layer 602. At this time, the circuit constructed by the power supply, current sensor 4523, conductor 4521, wire clamp, circular cutter 430 and steel armor layer 602 is disconnected. At the moment when the current changes from being present to being absent, the current sensor 4523 transmits a signal to the controller 201. The controller 201 controls the second motor 45141 to rotate in the opposite direction, thereby controlling the two circular cutters 430 to separate from each other, and at the same time controls the first motor 446 to rotate to lift the movable frame 443 for the subsequent stripping of the outer sheath 601 of the cable 600. An annular sliding groove 4526 is used here, and two conductive brushes 4525 are arranged in the sliding groove 4526. The purpose of setting a pulling rope 4527 is to ensure that the two wire clamps 4522 are always located at both ends of the sliding groove 4526 when the stripping work is not in progress. When one of the wire clamps 4522 moves to the position of the sliding groove 4526 close to the circular cutter 430, the other wire clamp 4522 will return to the position of the sliding groove 4526 away from the circular cutter 430 under the traction of the pulling rope 4527, so that the stripping of the outer sheaths 601 of two consecutive cables 600 can be carried out conveniently.

[0098] Reference Figure 11-Figure 14 As a specific implementation of an embodiment of the present application, in order to improve the stripping efficiency of the outer sheath 601, the present application evenly arranges heating wires 800 in the circular cutter 430.

[0099] In combination with specific usage scenarios, the outer sheath 601 of the cable 600 needs to be introduced here. The outer sheath 601 of the cable 600 is generally made of rubber. Since rubber has certain elasticity and toughness, it is troublesome to cut at room temperature. Frequent cutting of rubber at room temperature will cause uneven cuts and burrs, which will affect the cut quality of the outer sheath 601. In addition, long-term cutting of the outer sheath 601 at room temperature will easily cause the tool to become blunt, which will not only affect the cutting efficiency, but also further affect the cutting quality. The present application can heat the circular cutter 430 through a uniform heating wire 800. The temperature of the circular cutter 430 after heating is relatively high. Only when the circular cutter 430 contacts the outer sheath 601, the high temperature on the blade of the circular cutter 430 will cause the rubber at the cutting part to soften locally and rapidly, thereby accelerating the cutting speed and facilitating cutting. The heated circular cutter 430 can also make the rubber incision more neat, reduce burrs and tearing, avoid burr problems, and ensure the service life of the circular cutter 430.

[0100] Reference Figure 8 As a specific implementation of the embodiment of the present application, it also includes two third motors 900, and the two third motors 900 are respectively installed on the two supporting tool holders 420. The third motors 900 are mainly used to drive the two circular cutters 430 to rotate at high speed, and ensure that the rotation directions of the two circular cutters 430 are opposite; in addition, a conductive slip ring 901 is also installed on the supporting tool holder 420. The conductive slip ring 901 can ensure that there will be no line entanglement problem when the circular cutter 430 rotates at high speed, thereby ensuring the normal operation of the circuit of the cutting depth detection mechanism 452 and the heating wire 800.

[0101] In combination with specific usage scenarios, the third motor 900 is installed mainly to enable the circular cutter 430 to have a higher rotation speed, because the circular cutter 430 rotating at a high speed has a high linear speed and can generate a larger cutting force, thereby more effectively overcoming the elastic and viscous resistance of the rubber, making the cutting process smoother, and further improving the cutting efficiency of the outer sheath 601 of the cable 600. In addition, the high-speed rotation of the circular cutter 430 also reduces the deformation and pulling of the outer sheath 601 during the cutting process of the outer sheath 601, making the incision more neat and smooth, and further improving the incision quality of the outer sheath 601.

[0102] Reference Figure 1-Figure 3As a specific implementation of the embodiment of the present application, the clamping and conveying mechanism 500 includes a support roller group 510, a top pressure roller group 520 and two groups of side pressure wheels 530; the position of the support roller group 510 is fixed, and the top pressure roller group 520 is controlled to descend by the first clamping assembly 540 to clamp the cable 600 from the upper and lower sides of the cable 600, and the two groups of side pressure wheels 530 are controlled to approach each other by the second clamping assembly 550 to clamp the cable 600 from the left and right sides of the cable 600. When the longitudinal cutting work is performed, the support roller group 510 is controlled to rotate by the feeding assembly 560 to convey the cable 600. Here, the support roller group 510, the top pressure roller group 520 and the two groups of side pressure wheels 530 can be provided with anti-slip patterns to increase the friction between the outer sheath 601 of the cable 600, so that the cutting work of the cable 600 is smoother and more stable.
