Description

Technical Field

[0001] The invention provides a laser preheating waste tire steel wire recovery device, and particularly relates to the technical field of waste tire steel wire recovery. Background Art

[0002] With the rapid development of the automobile industry, the number of waste tires is increasing day by day. The effective recycling of waste tires, especially the recycling of steel wires, is of great significance for resource recycling and environmental protection. In the process of recycling steel wires from waste tires, the core goal is to separate the steel wires from the tire rubber efficiently and with high quality. In the prior art, a hook is generally used to hook the steel wire inside the tire and directly pull the steel wire out and separate it from the tire.

[0003] Application publication number CN118322420A discloses a waste tire separation wire drawing machine. When the wire drawing machine is used, a laser head that can rotate around the tire is used to cut the tire into two parts, and then a wire drawing hook is used to hook the steel wire to separate it from the tire.

[0004] However, in the process of horizontally pulling out the recycled steel wire by the above-mentioned wire drawing machine, on the one hand, the steel wire will be directly damaged, causing the steel wire to be cut off, and on the other hand, it does not take into account that the tire rubber has high viscosity and toughness, and the steel wire is tightly adhered to the rubber. This makes it difficult for the wire drawing hook to smoothly penetrate into the tire and hook the steel wire, resulting in low efficiency of the wire drawing hook hooking the steel wire. Moreover, due to the excessive viscosity between rubber and steel wire, a large pulling force needs to be applied when directly pulling out the steel wire horizontally, which can easily cause the steel wire to break due to excessive force, greatly increasing the damage rate of the steel wire during the pulling out and recycling process. Not only does it reduce the quality of steel wire recycling, it also causes a waste of resources, and also affects the efficiency of the entire waste tire recycling process.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Embodiments of the present invention are as follows: Embodiment 1: Figures 1 to 6 As shown, a laser preheated waste tire steel wire recycling device includes a base plate 1, two vertical plates 11 are symmetrically fixedly connected to the top surface of the base plate 1, a horizontal plate 12 is fixedly connected between the two vertical plates 11, a hydraulic telescopic cylinder 13 is fixedly installed between the two vertical plates 11 and above the horizontal plate 12, a wire drawing hook 14 is fixedly connected to the telescopic end of the hydraulic telescopic cylinder 13, and an external controller is installed on the base plate 1, and the controller can control the retraction and extension of the telescopic end of the hydraulic telescopic cylinder 13.

[0022] A rotary preheating mechanism is provided on the vertical plate 11, and the rotary preheating mechanism includes an annular plate 21 fixedly connected to one side of the two vertical plates 11, and a U-shaped plate 22 is fixedly provided on the side of the annular plate 21 away from the vertical plate 11, and the lower half of the U-shaped plate 22 is a semicircular structure, and a plurality of rollers 23 are rotatably connected to the inner wall of the semicircular part of the U-shaped plate 22, and the plurality of rollers 23 are equidistantly arranged in an annular manner in the U-shaped plate 22, specifically, the space between the U-shaped plate 22 and the annular plate 21 is used to place the old tires, and after the old tires are placed, the lower half of the tires are located in the lower half of the U-shaped plate 22, and the outer wall of the tires is in contact with the outer surface of each roller 23; and the outer surface of each roller 23 is provided with an anti-skid layer to increase the friction between the roller 23 and the tire, so that the tire can rotate. A driving motor 24 is fixedly installed at the bottom of the U-shaped plate 22 away from the annular plate 21, and the driving motor 24 is started and shut down by the above-mentioned controller. A large gear 25 is fixedly connected to the output shaft of the driving motor 24 near the U-shaped plate 22, and a small gear 251 is fixedly connected to a rotating roller 23 corresponding to the position of the large gear 25. The small gear 251 meshes with the large gear 25. A bottom hole for the large gear 25 to rotate is provided on the U-shaped plate 22. The top of the large gear 25 passes through the bottom hole and extends to the inside of the U-shaped plate 22. Specifically, the large gear 25 passes through the bottom hole and meshes with the small gear 251. A laser generator 26 is fixedly installed on the outer wall of one side of the U-shaped plate 22, and the laser generator 26 is started and shut down by the above-mentioned controller. A laser emitting head 27 is fixedly installed on the inner wall of the U-shaped plate 22 near the laser generator 26. The laser emitting head 27 is connected to the laser generator 26. When the old tire is placed between the annular plate 21 and the U-shaped plate 22, a gap is left between the laser emitting head 27 and the outer wall of the tire, and the laser emitted by the laser emitting head 27 can irradiate the outer surface of the tire.

[0023] Furthermore, the rotary preheating mechanism also includes an arc-shaped cavity plate 28 fixedly mounted on the inner wall of the U-shaped plate 22. The arc-shaped cavity plate 28 is located on the inner wall of the U-shaped plate 22 and close to a position below the laser emitting head 27. A plurality of air nozzles 281 are evenly connected and arranged on one side of the arc-shaped cavity plate 28 facing the center of the U-shaped plate 22. Specifically, when the old tire is placed, the outer wall of the tire will not contact each air nozzle 281. An air inlet pipe 29 is connected and arranged on one side of the arc-shaped cavity plate 28 away from the air nozzle 281. A valve is installed on the air inlet pipe 29. One end of the air inlet pipe 29 away from the gas nozzle 281 passes through the U-shaped plate 22 and extends to the outside of the U-shaped plate 22. Before use, the end of the air inlet pipe 29 located outside the U-shaped plate 22 is connected to a storage tank containing an inert gas, such as carbon dioxide. Specifically, the existing carbon dioxide gas cylinder can be threadedly connected to the air inlet pipe 29 through a tube body. After the valve is opened, the air inlet pipe 29 is connected to the arc cavity plate 28, that is, carbon dioxide can pass through the arc cavity plate 28 and be blown from the gas nozzle 281 to the inside of the U-shaped plate 22.

[0024] When in use: the staff holds the waste tire and moves it to the top of the U-shaped plate 22, first let the center of the waste tire pass horizontally through the wire drawing hook 14, and then put the waste tire downward between the U-shaped plate 22 and the annular plate 21. Figure 1 Status shown.

[0025] After the waste tire is placed between the U-shaped plate 22 and the annular plate 21, the outer wall of the waste tire contacts the outer wall of each roller 23. Then, the staff starts the driving motor 24 and the laser generator 26 through the controller at the same time. After the large gear 25 is started, its output end will drive the large gear 25 to start rotating, and then the rotation of the large gear 25 drives the small gear 251 to rotate in the opposite direction, and then the rotation of the small gear 251 drives a roller 23 to rotate synchronously, and as the roller 23 rotates, the friction between the roller 23 and the outer wall of the waste tire drives the waste tire to start rotating.

[0026] During this process, as the laser generator 26 is started, the laser emitting head 27 will emit a high-temperature laser, and the high-temperature laser will directly irradiate the outer surface of the waste tire, and as the waste tire continues to rotate, the waste tire as a whole will be gradually irradiated by the high-temperature laser, thereby causing the waste tire to gradually soften. After the waste tire softens to a suitable softness, the laser generator 26 and the drive motor 24 are turned off by the controller, and then the hydraulic telescopic cylinder 13 is started by the controller, causing the telescopic end of the hydraulic telescopic cylinder 13 to gradually begin to slowly retract horizontally, and as the hydraulic telescopic cylinder 13 is retracted, the wire drawing hook 14 will be prompted to gradually squeeze the outer wall of the waste tire, causing it to deform, and finally the wire drawing hook 14 will be prompted to enter the interior of the waste tire as the waste tire softens, and as the wire drawing hook 14 enters the interior of the waste tire, it will hook the steel wire inside the waste tire, so that as the hydraulic telescopic cylinder 13 is gradually retracted, the steel wire inside the waste tire will be gradually pulled out through the wire drawing hook 14.

[0027] During the process of pulling out the steel wire, the waste tire directly contacts the surface of the annular plate 21, which prevents the waste tire from being pulled out from between the annular plate 21 and the U-shaped plate 22. On the other hand, the steel wire is pulled out in a relatively horizontal state under the blocking effect of the annular plate 21. When all the steel wires are pulled out, the staff can manually take away the steel wires.

[0028] Therefore, by setting up a rotating preheating mechanism, before the steel wire is extracted from the waste tire, the outer wall thereof is evenly heated by a high-temperature laser, so that the waste tire is softened. The softened waste tire is more conducive to the wire drawing hook 14 to penetrate into the interior thereof, which not only makes it easier for the wire drawing hook 14 to hook the steel wire, but also makes it easier for the softened waste tire to separate the steel wire from the waste tire. Compared with the direct horizontal pulling method in the prior art, this method can speed up the separation of the steel wire from the waste tire, and at the same time avoid the situation in which the steel wire is broken due to excessive adhesion between the steel wire and the waste tire when the steel wire is directly pulled out horizontally, thereby greatly reducing the damage rate of the steel wire during the wire pulling and recycling process.

[0029] At the same time, considering that the laser heating process of the waste tire to soften the tire may cause the tire surface to burn, therefore, in the process of the waste tire being heated by the laser in a rotating state, when the heated part of the waste tire rotates to the position of the arc cavity plate 28, the gas nozzle 281 on the arc cavity plate 28 will release carbon dioxide gas, thereby using the carbon dioxide gas to isolate oxygen, avoiding the waste tire surface from burning during the laser softening process, thereby ensuring the safety of the waste tire softening process.

[0030] Embodiment 2: Figure 1 , Figure 2 as well as Figures 7 to 9 As shown, the above-mentioned laser preheating waste tire wire recycling device also includes a cooperating scraping mechanism arranged on the side of the annular plate 21 close to the vertical plate 11, and the cooperating scraping mechanism includes a preheating box 31 fixedly arranged on the side of the annular plate 21 close to the two vertical plates 11. The preheating box 31 is penetrated with a through hole 32 for the telescopic end of the hydraulic telescopic cylinder 13 and the wire drawing hook 14 to pass horizontally. The top surface of the preheating box 31 is fixedly installed with a power supply device 33. Specifically, the power supply device 33 is a battery pack. Two ceramic electric heating plates 34 are symmetrically fixedly installed on both sides of the preheating box 31. The two ceramic electric heating plates 34 are arranged in parallel and are located on both sides of the horizontal movement path of the wire drawing hook 14. The two ceramic electric heating plates 34 are both electrically connected to the power supply device 33, and the ceramic electric heating plates 34 and the power supply device 33 are both started and shut down by the controller on the bottom plate 1.

[0031] The scraping mechanism also includes two vertical slot frames 35 fixedly connected to the side of the preheating box 31 away from the annular plate 21. The interiors of the two vertical slot frames 35 are slidably connected with electromagnets 310. The bottom slot surfaces of the two vertical slot frames 35 are fixedly provided with magnet plates 351. Specifically, the magnetism of the two electromagnets 310 after being energized is opposite to the magnetism of the corresponding magnet plates 351. A spring 2 313 is connected between the top of the two electromagnets 310 and the top slot surface of the vertical slot frame 35. A scraper 311 is fixedly connected between the two electromagnets 310. The outer surface of the scraper 311 is provided with a non-stick layer, specifically a silicone coating, which can prevent the heated rubber from adhering to the surface of the scraper 311. The bottom of the scraper 311 is evenly provided with a plurality of scraping openings 312, and each scraping opening 312 can allow the steel wire inside the old tire to pass through. The bottom of each scraping opening 312 is triangular and the top is U-shaped. An L-shaped plate 36 is fixedly connected to the bottom of one side of the vertical groove frame 35, and a push switch 37 is fixedly installed on the side of the L-shaped plate 36 close to the vertical groove frame 35. A T-shaped rod 38 is movably inserted on the side of the L-shaped plate 36 away from the push switch 37. A spring 381 is connected between the outer wall of the T-shaped rod 38 and the outer wall of the L-shaped plate 36. The positions of the T-shaped rod 38 and the push switch 37 correspond to each other. A triangular block 39 is fixedly connected to the end of the T-shaped rod 38 away from the push switch 37. Inclined surfaces are provided on both sides. The inclined surfaces on both sides of the triangular block 39 are located on the path of horizontal movement of the wire drawing hook 14. The triangular block 39 is located at a position where the scraper 311 is away from the preheating box 31. That is to say, when the wire drawing hook 14 is retracted to this position, it will contact the inclined surface on one side of the triangular block 39, thereby prompting the T-shaped rod 38 to trigger the push switch 37, energizing the two electromagnets 310, and then prompting the scraper 311 to move downward, and the scraper 311 will not contact the wire drawing hook 14 during the downward movement. At the same time, there is a gap between the triangular block 39 and the scraper 311. The function of the gap is that when the wire drawing hook 14 is extended horizontally, its outer wall will contact the inclined surface on the other side of the triangular block 39, prompting the T-shaped rod 38 to press the push switch 37 again, and the two electromagnets 310 will be de-energized to ensure that the wire drawing hook 14 can pass between the two vertical slot frames 35 and return to the initial position.

[0032] When in use: before the wire drawing hook 14 draws out the steel wire, first start the two ceramic electric heating plates 34 through the controller. When the wire drawing hook 14 draws out the steel wire and drives the steel wire to slowly move into the preheating box 31, the two ceramic electric heating plates 34 will heat the passing steel wire from both sides. The two ceramic electric heating plates 34 are used to heat the passing steel wire, so that part of the rubber adhering to the outer surface of the steel wire is softened. After the rubber adhering to the outer surface of the steel wire is heated and softened, it can be better separated from the steel wire, so as to facilitate the subsequent scraping of the rubber adhering to the outer surface of the steel wire, and improve the scraping efficiency of the rubber adhering to the outer surface of the steel wire.

[0033] When the wire drawing hook 14 pulls the steel wire to the position of the triangular block 39, the outer wall of the wire drawing hook 14 contacts and squeezes the inclined surface of one side of the triangular block 39, causing the T-shaped rod 38 and the triangular block 39 to move horizontally toward the side close to the push switch 37, and the spring 1 381 is in a compressed state during the process. When the wire drawing hook 14 is flush with the position of the triangular block 39, the T-shaped rod 38 just contacts the push switch 37, thereby controlling the two electromagnets 310 to be energized through the push switch 37. When the electromagnets 310 are energized, the two electromagnets 310 will drive the scraper 311 and the scraper mouth 312 to move vertically downward, and the spring 2 313 will be stretched during the process, and the scraper mouth 312 will eventually move down to the path where the steel wire is pulled out, and the inner wall of the scraper mouth 312 will contact the outer wall of the steel wire. In this way, as the wire drawing hook 14 continues to move while pulling the steel wire, the softened rubber adhering to the outer surface of the steel wire will be scraped off by the scraping action of the scraping mouth 312. When the outer wall of the wire drawing hook 14 does not contact the triangular block 39, the T-shaped rod 38 will be reversely translated and reset under the action of the rebound force of the spring 1 381, and the T-shaped rod 38 will not control the two electromagnets 310 to be powered off, that is, the scraping mouth 312 will continue to contact the outer surface of the steel wire, thereby continuously scraping off the rubber adhering to the outer surface of the steel wire.

[0034] Therefore, by setting up a coordinated scraping mechanism, when the steel wire is pulled out, the scraping mouth 312 is in contact with the outer surface of the steel wire to scrape off the softened rubber, thereby preventing the rubber from adhering to the outer surface of the steel wire and affecting subsequent recycling. This reduces the tedious steps of subsequent manual processing of the rubber adhered to the outer surface of the steel wire, thereby improving the comprehensive recycling efficiency of the steel wire.

[0035] Embodiment 3: Figure 1 , Fig.10 , Fig.11As shown, the above-mentioned laser preheating waste tire steel wire recycling device also includes a follow-up cutting mechanism commonly arranged on the two vertical plates 11 and the horizontal plate 12, and the follow-up cutting mechanism includes a positioning frame 41 commonly fixedly connected between the two vertical plates 11, and the positioning frame 41 is located on a side of the two vertical plates 11 close to the driving motor 24. A receiving barrel 42 is fixedly connected to the horizontal plate 12 and located on a side close to the positioning frame 41. A discharge pipe 43 is connected to one side of the receiving barrel 42, and the discharge pipe 43 is arranged in an inclined manner. One end of the discharge pipe 43 away from the receiving barrel 42 passes through a vertical plate 11 and extends to the outside of the vertical plate 11. The positioning frame 41 is rotatably connected with a coaxial rod 44 and a vertical rod 46. The coaxial rod 44 is arranged vertically, and the vertical rod 46 is arranged horizontally. The end of the coaxial rod 44 away from the vertical rod 46 is coaxially fixedly connected to one side of the large gear 25, and the end of the coaxial rod 44 close to the vertical rod 46 is fixedly connected to a bevel gear 1 45, and the lower end of the vertical rod 46 is fixedly connected to a bevel gear 2 47 meshing with the bevel gear 1 45. The upper end of the vertical rod 46 passes through the bottom of the receiving barrel 42 and extends to the inside of the receiving barrel 42. The top of the vertical rod 46 is fixedly connected to a cutter head 48, which is composed of a plurality of inclined blades, and the plurality of blades are distributed in a ring. A filter plate 49 is fixedly installed inside the receiving barrel 42 and below the cutter head 48 , and a dial plate 410 is fixedly connected to the outer wall of the vertical rod 46 and below the filter plate 49 , and the bottom of the dial plate 410 fits with the bottom surface of the inside of the receiving barrel 42 .

[0036] When in use: At the same time, the rubber scraped off by the scraping mouth 312 will fall into the inside of the receiving barrel 42. When the steel wire of a waste tire is taken out, the next waste tire is rotated and preheated. As the driving motor 24 drives the large gear 25 to rotate, the large gear 25 will also drive the coaxial rod 44 and the bevel gear 1 45 to rotate synchronously, and then the rotation of the bevel gear 1 45 drives the meshing bevel gear 2 47 to rotate in the opposite direction, thereby driving the vertical rod 46 and the cutter head 48 to rotate synchronously through the bevel gear 2 47. As the cutter head 48 rotates, the rubber falling into the receiving barrel 42 is cut by using a plurality of blades distributed in an annular shape. After being cut, some small rubber particles will fall from the filter plate 49 to the bottom of the receiving barrel 42, while some rubber that fails to fall will continue to be cut inside the receiving barrel 42. After the small rubber particles fall into the bottom of the receiving barrel 42 after being cut, the rotation of the vertical rod 46 will also drive the paddle 410 to rotate synchronously, thereby gradually pushing the small rubber particles to the position of the discharge pipe 43. The discharge pipe 43 is set in an inclined manner. Under the action of gravity, the small rubber particles will be automatically discharged outward through the discharge pipe 43, and the fallen rubber particles can be received by an external container. The collected rubber particles can be made into new rubber products again after passing through a special melting processing equipment.

[0037] Therefore, through the follow-up cutting mechanism, the rubber scraped off the outer wall of the steel wire can be automatically crushed and some strips and blocks of rubber can be automatically cut into small particles, which not only facilitates the subsequent recycling of the rubber, but also improves the recycling efficiency of the adhered rubber during the steel wire recycling process.
