Description

Technical Field

[0001] The present invention relates to the technical field of cable recycling, and in particular to an environmentally friendly recycling and processing device for cable insulation materials. Background Art

[0002] Existing cable insulation material recycling equipment is mainly used to process discarded cables. Through a series of operations, the insulation material in the cable is separated from the battery core, and then the insulation material is recycled, creating conditions for subsequent processing and utilization, so as to achieve resource recycling and environmental protection goals.

[0003] After searching, the announcement number is CN113245346B, which discloses a cable rotation recovery device, including a stripping mechanism, a rotating mechanism, a clamping mechanism, a clamping force adjustment mechanism, a one-way clamping mechanism, a linear moving mechanism, an end positioning mechanism and a cutting mechanism. The cable rotation recovery device is combined with a clamping force adjustment mechanism, a one-way clamping mechanism and a clamping mechanism. The clamping mechanism is used to clamp the cable so that the cable is clamped in the center to avoid the cable from being deflected during the twisting process, which causes the cable to shake during the twisting process. The worker pulls open the one-way clamping mechanism and then tightens the cable in one direction. When encountering a pillar, the pillar automatically opens the one-way clamping mechanism, and the clamping mechanism no longer clamps the cable. The worker only needs to stand next to the cutting mechanism, saving a lot of time for the worker.

[0004] However, because the conveying components do not fully consider the circular outer contour of the cable, the contact area with the cable is small, resulting in insufficient friction. At the same time, the lack of a structure that can enhance friction makes the cable easily affected by external factors during transportation and causes deviation or stagnation, seriously affecting the normal progress of subsequent processing procedures. As a result, slippage often occurs during the cable transportation process, making it difficult to transport the cable continuously and stably.

[0005] In addition, when cutting the cable insulation sheath, it is difficult to flexibly and accurately adjust the cutting depth according to the different thicknesses of the insulation sheath, which can lead to two undesirable results: either the cutting is too shallow and the insulation sheath is not effectively cut; or the cutting is too deep, damaging the internal battery core. The insulation sheath after cutting is in the form of long strips, which brings great difficulties to subsequent recycling processes such as crushing and melting.

[0006] Therefore, it is necessary to provide an environmentally friendly recycling and processing device for cable insulation materials to solve the above problems. Summary of the Invention

[0021] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0022] See also Figures 1 to 9 , embodiments provided by the present invention:.

[0023] like Figure 1 and Figure 2 As shown, an environmentally friendly recycling and processing device for cable insulation materials includes a feeding assembly 1 for transporting cables to achieve stable transportation of discarded cables and provide a continuous source of materials for subsequent processing. The feeding assembly 1 includes a feeding frame 11, a driving mechanism 12 and two feeding rollers 15. The driving mechanism 12 is installed on the bottom surface of the feeding frame 11. The two feeding rollers 15 are rotatably installed on the inner two sides of the feeding frame 11 respectively. The driving mechanism 12 drives the two feeding rollers 15 to rotate in the feeding frame 11.

[0024] Among them, Figure 3 As shown, the driving mechanism 12 includes a first driving motor 121, a mounting frame 122, two driving gears 123 and two driven gears 124. The two driving gears 123 are rotatably mounted on the bottom surface of the feeding frame 11 through a shaft, and the two driving gears 123 are meshedly connected. The two driven gears 124 are respectively connected to the rotating shaft keys of the two feeding rollers 15, and the two driven gears 124 are respectively meshedly connected to the side walls of the two driving gears 123. One of the driving gears 123 is keyed to the output shaft of the first driving motor 121, and the first driving motor 121 is fixedly mounted on the bottom surface of the feeding frame 11 through the mounting frame 122.

[0025] The first drive motor 121 in the drive mechanism 12 serves as a power source, and drives a driving gear 123 keyed to it to rotate through the output shaft. Since the two driving gears 123 are engaged with each other, when the first driving gear 123 rotates, it will drive the other driving gear 123 to rotate in the opposite direction, and the driving gear 123 is engaged with the driven gear 124 on the rotating shaft of the feed roller 15, which makes the two feed rollers 15 rotate in opposite directions in the feed frame 11, and uses friction to transport the cable forward.

[0026] Furthermore, the side wall of the feed roller 15 is provided with an inwardly concave arc surface 16, and convex strips 17 are fixed at equal intervals around the arc surface 16. The inwardly concave arc surface 16 can better fit the circular outer contour of the cable, greatly increasing the contact area between the feed roller 15 and the cable. The increase in contact area can effectively increase the friction between the two, thereby avoiding the cable from slipping during transportation and ensuring the stability of transportation. The convex strips 17 fixed at equal intervals on the arc surface 16 further enhance the friction, ensuring reliable transportation.

[0027] Furthermore, a groove 13 is provided on the inner bottom surface of the feeding frame 11, and a plurality of guide rollers 14 are rotatably connected in the groove 13, and the side walls of the plurality of guide rollers 14 are provided with an inwardly concave arc surface 16. The arc surface 16 can fit the circular outer contour of the cable, and cooperate with the feeding roller 15 to form an upper and lower clamping guide structure, which assists in supporting the cable from below to prevent deviation during transportation, reduce friction resistance during cable transportation, make transportation smoother, and ensure stable movement of the cable.

[0028] like Figure 1 and Figure 4 As shown, the side wall of the feeding assembly 1 is fixedly mounted to the stripping assembly 3 via the connecting frame 2. The stripping assembly 3 is mainly used to cut the insulation sheath of the cable. The stripping assembly 3 includes a first guide cylinder 31, a cutter 33, and a cutting angle adjustment mechanism 34. The cutter 33 is movably mounted inside the first guide cylinder 31. The cutting angle adjustment mechanism 34 is threadedly connected to the side wall of the first guide cylinder 31 and is hinged to one end of the cutter 33. Specifically, a plurality of first hinge seats 32 are fixedly connected to an inner circle of the first guide cylinder 31 , one end of the cutter 33 is rotatably mounted on the first hinge seat 32 , and the other end of the cutter 33 is hinged to the cutting angle adjustment mechanism 34 .

[0029] like Figure 5 As shown, the cutting angle adjustment mechanism 34 includes an internal threaded ring 341, a handle 342, a tapered cylinder 343, a slide groove 344, a slide rod 345 and a second hinge seat 346. The outer wall of the first guide cylinder 31 is provided with a threaded groove 35, and the internal threaded ring 341 is threadedly connected to the threaded groove 35. The handle 342 is installed on the outer wall of the internal threaded ring 341, and the side wall of the internal threaded ring 341 is rotatably installed with the tapered cylinder 343. The inner side of the tapered cylinder 343 is respectively provided with a slide groove 344, and one end of the slide rod 345 is slidably installed in the slide groove 344. The side walls of the first guide cylinder 31 are respectively provided with a slot, and the slide rod 345 is slidably connected in the slot. The other end of the slide rod 345 is fixedly installed with the second hinge seat 346, and the second hinge seat 346 is rotatably installed with the other end of the cutter 33.

[0030] Working principle: When the cable passes through the first guide cylinder 31, multiple cutters 33 cut the insulating sleeve under the control of the cutting angle adjustment mechanism 34. The cutting angle adjustment mechanism 34 rotates the handle 342 to make the internal thread ring 341 rotate on the thread groove 35 of the first guide cylinder 31 and generate axial movement, thereby driving the cone cylinder 343 to move left and right. The slide groove 344 on the inner side of the cone cylinder 343 cooperates with the slide rod 345. When the cone cylinder 343 moves, the slide rod 345 will slide up and down in the slot. Since the slide rod 345 is hinged to the other end of the cutter 33 through the second hinge seat 346, and one end of the cutter 33 is rotatably connected to the first hinge seat 32, the movement of the slide rod 345 will change the inclination angle of the cutter 33, thereby adjusting the cutting depth, so as to flexibly adjust the cutting depth according to the thickness of the insulation sleeve of different cables, thereby ensuring that the insulation sleeve is effectively cut and avoiding damage to the internal battery core, thereby improving the adaptability and accuracy of the stripping process.

[0031] like Figure 1 and Figure 6 As shown, the material guide assembly 4 is fixedly mounted on the side wall of the first guide cylinder 31. The material guide assembly 4 is used to separate the cut insulating sleeve and the cable core. The material guide assembly 4 includes a first outer cylinder 41, an inner cylinder 42 and a first partition 43. The first outer cylinder 41 is fixedly mounted on the side wall of the first guide cylinder 31, and the inner cylinder 42 is inserted into the interior of the first guide cylinder 31. The first outer cylinder 41 and the inner cylinder 42 are fixedly connected by a plurality of first partitions 43. Among them, Figure 7 As shown, the ends of the plurality of first partitions 43 located in the first guide cylinder 31 are each provided with a first cutting edge 431, and the inner cylinder 42 is tapered; Working principle: After the cut cable enters the guide assembly 4, the insulating sleeve will be blocked by the first partition 43 and cannot continue to move in a straight line with the battery cell. Since the inner cylinder 42 is conical and the first outer cylinder 41 and the inner cylinder 42 are connected by multiple first partitions 43, multiple gaps are formed. The insulating sleeve will slide out along the outer wall of the inner cylinder 42 and these gaps respectively, while the battery cell part of the cable can continue to be transported through the inner cylinder 42. At the same time, the first blade 431 at the end of the first partition 43 in the first guide cylinder 31 can also further separate and guide the insulating sleeve, thereby realizing effective separation of the insulating sleeve and the battery cell, avoiding the mixing of the two and affecting subsequent processing, ensuring that the insulating sleeve can be smoothly guided to the designated path, and the battery cell continues to be transported unimpeded, which provides convenience for subsequent insulating sleeve processing and battery cell recycling.

[0032] like Figure 8 and Figure 9As shown, the cutting component 5 is fixedly mounted on the side wall of the material guide component 4. The function of the cutting component 5 is to cut the strip-shaped insulating sleeve into small segments. The cutting component 5 includes a second guide cylinder 51, a second partition 52, a second outer cylinder 53 and a circular cutting mechanism 57. The side wall of the second guide cylinder 51 is fixedly connected to the second outer cylinder 53 through the second partition 52. The side wall of the second outer cylinder 53 is installed with a limiting seat 54. The limiting seat 54 is rotatably installed with the circular cutting mechanism 57. A driving source is installed on the limiting seat 54, and the driving source is engaged with the side wall of the circular cutting mechanism 57.

[0033] Specifically, the circular cutting mechanism 57 includes a rotating ring 571, a limiting ring 573 and a second cutting edge 574. The outer wall of the rotating ring 571 is provided with an annular tooth groove 572. The side walls of the rotating ring 571 are fixedly connected to the limiting ring 573 respectively. The outer peripheries of the limiting ring 573 and the rotating ring 571 are rotatably connected in the limiting seat 54. An eccentric second cutting edge 574 is provided on the inner side of the limiting ring 573. The driving source includes a second driving motor 55 and a driving gear 56. The second driving motor 55 is installed on the limiting seat 54. The driving gear 56 is keyed to the output shaft of the second driving motor 55. The side wall of the driving gear 56 is meshed with the annular tooth groove 572.

[0034] After the cut insulating sleeve is separated by the first partition 43, it enters the gap between the second partition 52. The second driving motor 55 in the driving source drives the driving gear 56 to rotate. The driving gear 56 engages with the annular tooth groove 572 on the outer wall of the rotating ring 571, thereby driving the rotating ring 571 to rotate. The limiting rings 573 on both sides of the rotating ring 571 rotate in the limiting seat 54, ensuring the stability of the rotation of the rotating ring 571. Since the second blade 574 on the inner side of the limiting ring 573 is eccentrically set, when the rotating ring 571 rotates, the second blade 574 will periodically cut the strip insulating sleeve entering the gap and cut it into multiple small segments. The second guide cylinder 51, the second partition 52 and the second outer cylinder 53 together constitute the conveying and cutting space for the insulating sleeve. The limiting seat 54 provides an installation and limiting basis for the circular cutting mechanism 57 and the driving source, cutting the strip insulating sleeve into small segments, greatly reducing the difficulty of subsequent crushing and melting recovery processes, improving the efficiency of recycling, and making the insulating material easier to reprocess and utilize.

[0035] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
