Description

Technical Field

[0001] The invention belongs to the technical field of cable recovery, in particular to a cable sheath recovery device. Background Art

[0002] Cables are wire products used to transmit electrical energy or information, and are mainly composed of a wire core and an outer sheath. Cables are common and indispensable in daily life. Since cables need to be replaced and repaired regularly, a large number of waste cables will be generated. Waste cables still have recycling value. The recycled waste cables need to separate the wire core and the sheath, and then be recycled separately.

[0003] After the scrap cables are recycled, a wire stripping machine will be used to cut the cable sheath to expose the wire core inside the cable. Afterwards, the staff will take the wire core out of the cut sheath, separate the sheath and the wire core, and finally, recycle the sheath and the wire core separately.

[0004] After the sheath and core of the cable are separated, the sheath is elastic and in a long strip shape, so that when the sheath is stored, there will be large gaps between the sheaths, so that the storage and transportation of the sheath requires a lot of space, which greatly increases the cost of storage and transportation.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 6 As shown, a cable sheath recovery device described in an embodiment of the present invention comprises an operating table 1; a stripping unit is arranged in the middle of the operating table 1; a feeding unit is arranged at one end of the top surface of the operating table 1; crushing units are arranged on both sides of the other end of the top surface of the operating table 1; the crushing unit comprises a cylinder 2; two cylinders 2 are fixedly connected to both sides of the end of the top surface of the operating table 1 away from the feeding unit; rotating rods 3 are rotatably installed on both sides of the inside of the cylinder 2; a feeding port 4 is provided at the bottom of the end of the cylinder 2 away from the feeding unit; a crushing blade 5 is fixedly connected to the outer ring of the rotating rod 3; the crushing blades 5 on both sides are staggered; a No. 1 gear 6 is fixedly connected to the outer ring of the end of the rotating rod 3 away from the feeding unit; the No. 1 gears 6 on both sides are meshed with each other; a No. 1 motor 7 is fixedly connected to the end of the cylinder 2 away from the feeding unit; the rotating shaft of the No. 1 motor 7 is fixedly connected to one side of the rotating rod 3;

[0037] During operation, the recovered cables are transported to the stripping unit through the feeding unit on the top of the operating table 1. The stripping unit cuts the sheath of the cable into two halves, and the two halves of the sheath are transported to the crushing units on both sides. The two halves of the sheath enter the interior of the cylinder 2. At this time, the No. 1 motor 7 drives the rotating rod 3 on one side to rotate, and drives the No. 1 gear 6 on this side to rotate. Since the No. 1 gears 6 on both sides are meshed with each other, the rotating rods 3 on both sides rotate in opposite directions, driving the crushing blades 5 on both sides to rotate. The crushing blades 5 staggered on both sides cut and crush the sheath entering the interior of the cylinder 2 to form small-volume sheath fragments; the crushed sheath fragments fall from the discharge port 4 of the cylinder 2; thereby, the larger long strip sheath is crushed into small-volume sheath fragments, thereby reducing the space required for storage and transportation, and reducing the cost of storage and transportation; and the cable sheath also needs to be crushed after being recycled, which is also convenient for subsequent recycling and utilization.

[0038] like Figures 1 to 5 As shown, the end of the cylinder 2 close to the feeding unit is fixedly connected to a box 8; an arc-shaped channel 9 is provided inside the box 8; one end of the arc-shaped channel 9 is connected to the middle of the cylinder 2; the other end of the arc-shaped channel 9 passes through the side of the box 8 close to the middle of the operating table 1; a plurality of ventilation slots 10 are evenly provided on one side of the arc-shaped channel 9 close to the middle of the box 8; a fan 11 is provided at one end of the box 8 close to the feeding unit;

[0041] During operation, after the stripping unit cuts the sheath of the cable into two halves, the sheaths on both sides will bend to both sides and separate, and the sheaths on both sides will enter the guide cylinder 14, and guided by the inclined top surface of the guide cylinder 14, the sheaths will bend downward and be inserted into the middle of the conveying cylinder 12, and the ends of the sheaths will be inserted between the conveying wheels 13 on both sides. At this time, the motor drives the conveying wheels 13 on both sides to rotate, and the conveying wheels 13 on both sides clamp the sheaths and convey them toward the inside of the box body 8. The sheaths are conveyed to the arc-shaped channel 9 inside the box body 8, and the arc-shaped channel 9 guides the sheaths so that the sheaths enter the inside of the cylinder body 2; thereby improving the accuracy of the sheaths entering the inside of the cylinder body 2, which is beneficial to the continuous crushing of the sheaths;

[0042] When the crushing blade 5 cuts the sheath into powder, the fan 11 draws outside air into the interior of the box 8 to generate strong wind. After the strong wind passes through the ventilation slots 10 and the arc-shaped channel 9, the strong wind enters the interior of the cylinder 2, blowing the crushed sheath fragments toward the discharge port 4 of the cylinder 2, thereby avoiding the accumulation of the crushed sheath fragments inside the cylinder 2, affecting the crushing work of the sheath, and is beneficial to the discharge of the sheath fragments.

[0043] like Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, the feeding unit includes a trapezoidal bar seat 15; two of the trapezoidal bar seats 15 are arranged on the top surface of the operating table 1 at one end away from the crushing unit; the trapezoidal bar seats 15 are symmetrically arranged; the inclined surfaces of the trapezoidal bar seats 15 on both sides are close to each other; a plurality of card slots 16 are evenly provided on the side where the trapezoidal bar seats 15 on both sides are close to each other; the card slots 16 on both sides are staggered; a plurality of door frames 17 are evenly fixed to the top surface of one end of the operating table 1 away from the crushing unit; a shell 18 is provided at the bottom of the plurality of door frames 17; feeding wheels 19 are rotatably installed at both ends of the bottom of the shell 18; a tooth groove is provided around the outer ring of the feeding wheel 19, and a concave surface is provided in the middle of the outer ring of the feeding wheel 19; a driving component is provided on the top of the shell 18, and the driving component drives the feeding wheel 19 to rotate;

[0045] During operation, the recovered cables are placed on the top between the trapezoidal bar seats 15 on both sides, so that the trapezoidal bar seats 15 on both sides hold up the cables; the No. 2 motor 22 drives the No. 2 synchronous wheel 23 to rotate, and through the transmission of the No. 2 synchronous wheel 23 and the No. 2 synchronous belt 24, drives a feeding wheel 19 to rotate, and then through the transmission of the No. 1 synchronous wheel 20 and the No. 1 synchronous belt 21, drives another feeding wheel 19 to rotate, so that the two feeding wheels 19 rotate synchronously, and the two feeding wheels 19 convey the cables to the stripping unit, thereby completing the cable conveying work;

[0046] By providing the trapezoidal bar seat 15 and providing the tooth grooves and concave surface on the outer ring of the feeding wheel 19, not only the rolling deviation of the cable during the transportation process is avoided, but also the accuracy of the cable transportation is improved.

[0051] During operation, the distance between the two stripping knives 32 is adjusted according to the diameter of the cable and the thickness of the sheath, so that the blade of the stripping knife 32 can completely cut the sheath of the cable; the No. 2 screw 35 is rotated to drive the top plate 34 and the No. 2 guide rod 33 to rise and fall, drive the top stripping knife 32 to rise and fall, and control the height of the top stripping knife 32; the driving rod 40 is rotated to drive the No. 4 gear 43 to rotate, drive the No. 3 gear 42 and the No. 2 gear 41 to rotate, so that the two No. 2 gears 41 rotate synchronously, drive the bottom plate 37 to rise and fall inside the lifting slot 36, thereby controlling the bottom stripping knife 32 to rise and fall; this makes it convenient for the staff to control and adjust the height of the two stripping knives 32 and the distance between the two stripping knives 32;

[0052] Through the transmission of the drive rod 40, the second gear 41, the third gear 42 and the fourth gear 43, the staff only needs to operate on the top surface of the operating table 1 to control the lifting of the peeling knife 32 at the bottom, thereby facilitating the operation of the staff.

[0053] like Fig.12 and Fig.13As shown, a separation assembly is provided at one end of the peeling knife 32 close to the crushing unit; the separation assembly includes a U-shaped elastic plate 44; the U-shaped elastic plate 44 is fixedly connected to one end of the peeling knife 32 close to the crushing unit; a No. 4 screw 45 is rotatably installed in the middle of the U-shaped elastic plate 44; both sides of the middle of the U-shaped elastic plate 44 are provided with a slide groove 46; a support rod 47 is slidably installed between the slide grooves 46 on both sides; the No. 4 screw 45 passes through the middle of the support rod 47, and the No. 4 screw 45 is threadedly matched with the support rod 47;

[0054] During operation, after the peeling knife 32 cuts the sheath, the two halves of the sheath are guided by the outer walls of the two sides of the U-shaped elastic plate 44, so that the sheath is separated to both sides; the staff rotates the No. 4 screw 45 to drive the support rod 47 to slide along the slide groove 46, and controls the expansion degree of the side panels on both sides of the U-shaped elastic plate 44, so that the staff can control and adjust the sheath to accurately enter the interior of the material guide barrel 14.

[0055] Working principle: According to the diameter of the cable and the thickness of the sheath, the distance between the two stripping knives 32 is adjusted so that the blade of the stripping knife 32 can completely cut the sheath of the cable; the No. 2 screw 35 is rotated to drive the top plate 34 and the No. 2 guide rod 33 to move up and down, drive the top stripping knife 32 to move up and down, and control the height of the top stripping knife 32; the driving rod 40 is rotated to drive the No. 4 gear 43 to rotate, drive the No. 3 gear 42 and the No. 2 gear 41 to rotate, so that the two No. 2 gears 41 rotate synchronously, drive the bottom plate 37 to move up and down inside the lifting slot 36, and control the lifting of the bottom stripping knife 32;

[0056] The staff rotates the No. 4 screw 45 to drive the support rod 47 to slide along the slide groove 46, and controls the degree of expansion of the side plates on both sides of the U-shaped elastic plate 44, so that the sheath cut by the peeling knife 32 accurately enters the interior of the guide barrel 14;

[0057] The bidirectional screw 27 is rotated to drive the two sliders 26 inside the middle transverse groove 25 to slide, driving the trapezoidal bar seats 15 on both sides to slide along the transverse groove 25, and controlling the distance between the trapezoidal bar seats 15 on both sides; the No. 1 screw 29 is rotated to drive the housing 18 and the No. 1 guide rod 28 to rise and fall, and control the height of the feeding wheel 19;

[0058] The recovered cables are placed on the top between the trapezoidal bar seats 15 on both sides, so that the trapezoidal bar seats 15 on both sides hold up the cables; the No. 2 motor 22 drives the No. 2 synchronous wheel 23 to rotate, and through the transmission of the No. 2 synchronous wheel 23 and the No. 2 synchronous belt 24, drives a feeding wheel 19 to rotate, and then through the transmission of the No. 1 synchronous wheel 20 and the No. 1 synchronous belt 21, drives another feeding wheel 19 to rotate, so that the two feeding wheels 19 rotate synchronously, and the two feeding wheels 19 convey the cables to the stripping unit;

[0059] The cable passes through the housing 31, and the two stripping knives 32 cut the cable sheath into two halves; the two halves of the sheath are guided by the outer walls of the U-shaped elastic plate 44 on both sides, so that the sheath is separated to both sides, and the sheaths on both sides enter the guide cylinder 14, and are guided by the inclined top surface of the guide cylinder 14, so that the sheath is bent downward and inserted into the middle of the conveying cylinder 12, and the end of the sheath is inserted between the conveying wheels 13 on both sides. At this time, the motor drives the conveying wheels 13 on both sides to rotate, and the conveying wheels 13 on both sides clamp the sheath and convey it to the inside of the box body 8. The sheath is conveyed to the arc channel 9 inside the box body 8, and the arc channel 9 guides the sheath so that the sheath enters the inside of the cylinder 2;

[0060] At this time, the No. 1 motor 7 drives the rotating rod 3 on one side to rotate, and drives the No. 1 gear 6 on the side to rotate. Since the No. 1 gears 6 on both sides are meshed and transmitted with each other, the rotating rods 3 on both sides rotate in opposite directions, driving the crushing blades 5 on both sides to rotate. The crushing blades 5 staggered on both sides cut and crush the sheath entering the inside of the cylinder 2 to form small-volume sheath fragments; at the same time, the fan 11 sucks the outside air into the interior of the box 8 to generate strong wind. After the strong wind passes through the ventilation slots 10 and the arc channel 9, the strong wind enters the interior of the cylinder 2, blowing the crushed sheath fragments toward the discharge port 4 of the cylinder 2, and the crushed sheath fragments fall from the discharge port 4 of the cylinder 2; thereby, the large-volume long strip sheath is crushed into small-volume sheath fragments, thereby reducing the space required for storage and transportation, and reducing the cost of storage and transportation; and the cable sheath also needs to be crushed after recycling, which is also convenient for subsequent recycling and utilization.
