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 automotive industry, the number of scrap tires is increasing. The effective recycling of scrap tires, especially the recovery of the steel wire, is crucial for resource recycling and environmental protection. The core goal of scrap tire steel wire recycling is to efficiently and efficiently separate the steel wire from the tire rubber. Existing methods typically use a hook to directly pull the steel wire from the tire and separate it.

[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 drawing the recycled steel wire by the above-mentioned wire drawing machine, on the one hand, the steel wire will be directly damaged, causing it to be cut off. 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 the interior of 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 the rubber and the steel wire, a large pulling force needs to be applied when directly drawing 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 drawing and recycling process. This not only reduces the quality of the recycled steel wire, but also causes a waste of resources, while also affecting the efficiency of the entire waste tire recycling process.

[0005] Therefore, the present invention proposes a laser preheating waste tire steel wire recycling device to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0018] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0019] The laser preheating waste tire steel wire recovery device uses a rotating preheating mechanism to uniformly heat the outer wall of the waste tire with a high-temperature laser before extracting the steel wire, causing the waste tire to soften. The softened waste tire is more convenient for the wire drawing hook to penetrate into the interior, which not only makes it easier for the wire drawing hook to hook the steel wire, but also makes it easier for the steel wire to be separated from the waste tire after the softening. 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 avoid the situation where 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 significantly reducing the damage rate of the steel wire during the pulling and recycling process.

[0020] The carbon dioxide gas released by the air nozzle on the arc-shaped cavity plate isolates oxygen by using the carbon dioxide gas to avoid burning on the surface of the waste tire during the laser softening process, thereby ensuring the safety of the waste tire softening operation;

[0021] Two ceramic electric heating plates are used to heat the steel wire as it passes through, causing the rubber adhering to the outer surface of the steel wire to soften. After being heated and softened, the rubber adhering to the outer surface of the steel wire can be better separated from the steel wire, thereby facilitating the subsequent scraping of the rubber adhering to the outer surface of the steel wire, thereby improving the scraping efficiency of the rubber adhering to the outer surface of the steel wire;

[0022] Through the provided scraping mechanism, when the steel wire is being pulled out, the scraping mouth contacts the outer surface of the steel wire and scrapes 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 manual processing of rubber adhering to the outer surface of the steel wire, thereby improving the comprehensive recycling efficiency of the steel wire.

[0023] 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. This 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.

[0040] The present invention will be further described below with reference to the embodiments.

[0041] The embodiments of the present invention are as follows:

[0042] Example 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, which can control the retraction and extension of the telescopic end of the hydraulic telescopic cylinder 13.

[0043] A rotary preheating mechanism is provided on the vertical plate 11. The rotary preheating mechanism includes an annular plate 21 fixedly connected to one side of the two vertical plates 11. A U-shaped plate 22 is fixedly provided on the side of the annular plate 21 away from the vertical plate 11. 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 portion of the U-shaped plate 22. The plurality of rollers 23 are annularly and equidistantly arranged within the U-shaped plate 22. Specifically, the space between the U-shaped plate 22 and the annular plate 21 is used to place used tires. After the used tires are placed, the lower half of the tire is located within the lower half of the U-shaped plate 22, and the outer wall of the tire contacts the outer surface of each roller 23. 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 to facilitate tire rotation. A drive motor 24 is fixedly installed at the bottom of the U-shaped plate 22 away from the annular plate 21. The drive motor 24 is started and stopped by the above-mentioned controller. A large gear 25 is fixedly connected to the output shaft of the drive motor 24 on the side near the U-shaped plate 22. 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. The U-shaped plate 22 has a bottom hole for the large gear 25 to rotate. The top of the large gear 25 passes through the bottom hole and extends into the interior 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 mounted on the outer wall of one side of the U-shaped plate 22. The laser generator 26 is activated and deactivated by the aforementioned controller. A laser emitter 27 is fixedly mounted on the inner wall of the U-shaped plate 22 near the laser generator 26. The laser emitter 27 is connected to the laser emitter 26. When the used tire is placed between the annular plate 21 and the U-shaped plate 22, a gap is left between the laser emitter 27 and the outer wall of the tire, allowing the laser emitted by the laser emitter 27 to illuminate the outer surface of the tire.

[0044] Furthermore, the rotary preheating mechanism includes an arc-shaped cavity plate 28 fixedly mounted on the inner wall of the U-shaped plate 22. This cavity plate 28 is located on the inner wall of the U-shaped plate 22, near the bottom of the laser emitting head 27. Multiple air nozzles 281 are evenly connected to the side of the cavity plate 28 facing the center of the U-shaped plate 22. Specifically, after the used tire is placed, the outer wall of the tire does not contact each air nozzle 281. An air inlet pipe 29 is also connected to the side of the cavity plate 28 away from the air nozzles 281. A valve is installed on the air intake pipe 29. The end of the air intake 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 intake pipe 29 located outside the U-shaped plate 22 is connected to a storage tank containing inert gas, such as carbon dioxide. Specifically, the existing carbon dioxide cylinder can be threadedly connected to the air intake pipe 29 through the tube body. After the valve is opened, the air intake pipe 29 is connected to the arc-shaped cavity plate 28, that is, carbon dioxide can be blown from the gas nozzle 281 to the inside of the U-shaped plate 22 through the arc-shaped cavity plate 28.

[0045] 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 The status shown.

[0046] 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 simultaneously activates the drive motor 24 and the laser generator 26 through the controller. As the large gear 25 starts, its output drives the large gear 25 to begin rotating. This rotation of the large gear 25 then drives the small gear 251 to rotate in the opposite direction, which in turn drives one of the rollers 23 to rotate synchronously. As the roller 23 rotates, the friction between the roller 23 and the outer wall of the waste tire causes the waste tire to begin rotating.

[0047] During this process, as the laser generator 26 is activated, the laser emitting head 27 emits a high-temperature laser, which directly irradiates the outer surface of the waste tire. As the waste tire continues to rotate, the waste tire as a whole is 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. Subsequently, the hydraulic telescopic cylinder 13 is activated by the controller, causing the telescopic end of the hydraulic telescopic cylinder 13 to gradually begin to slowly retract horizontally. As the hydraulic telescopic cylinder 13 retracts, the wire drawing hook 14 is prompted to gradually squeeze the outer wall of the waste tire, causing it to deform, and finally prompting the wire drawing hook 14 to enter the waste tire as it softens. After the wire drawing hook 14 enters the waste tire, it will hook the steel wire inside the waste tire. As the hydraulic telescopic cylinder 13 gradually retracts, the steel wire inside the waste tire will be gradually pulled out through the wire drawing hook 14.

[0048] During the wire pulling process, the waste tire directly contacts the surface of the annular plate 21. This prevents the tire from being pulled out from between the annular plate 21 and the U-shaped plate 22. Furthermore, the annular plate 21 blocks the wire, ensuring it remains relatively horizontal. Once the wire is fully pulled out, the staff can manually remove it.

[0049] Therefore, by setting up a rotary preheating mechanism, before the steel wire is extracted from the waste tire, the outer wall of the waste tire 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 its interior, 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 where 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 pulling and recycling process.

[0050] At the same time, considering that laser heating of scrap tires may cause surface burns during the softening process, when the scrap tire is rotating and receiving laser heating, when the heated portion of the scrap tire rotates to the position of the arc-shaped cavity plate 28, the gas nozzle 281 on the arc-shaped cavity plate 28 will release carbon dioxide gas, thereby isolating oxygen with carbon dioxide gas, preventing the scrap tire from burning during the laser softening process, thereby ensuring safety during the scrap tire softening process.

[0051] Example 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. 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 fixed on both sides of the interior 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. 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.

[0052] 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. Each slot frame 35 has an electromagnet 310 slidably connected to its interior. A magnet plate 351 is fixedly mounted on the bottom slot surface of each slot frame 35. Specifically, when energized, the magnetism of each electromagnet 310 is opposite to that of the corresponding magnet plate 351. A spring 313 is connected between the top of each electromagnet 310 and the top slot surface of the slot frame 35. A scraper 311 is fixedly mounted between the two electromagnets 310. The outer surface of the scraper 311 is coated with a non-stick coating, specifically a silicone coating, to prevent the heated rubber from adhering to the scraper 311. The bottom of the scraper 311 is uniformly provided with multiple scraping openings 312, each of which is designed to allow the steel wire inside the used tire to pass through. Each scraper opening 312 is triangular at the bottom and U-shaped at the top. An L-shaped plate 36 is fixedly connected to the bottom of one side of the vertical groove frame 35. A push-type 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-type 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-type 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-type 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-type 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, a gap is left 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-type switch 37 again, de-energizing the two electromagnets 310, so as to ensure that the wire drawing hook 14 can pass between the two vertical slot frames 35 and return to its initial position.

[0053] In Use: Before the wire drawing hook 14 draws the wire, the controller activates the two ceramic electric heating plates 34. Once the wire drawing hook 14 draws the wire and slowly moves it into the preheating box 31, the two ceramic electric heating plates 34 heat the passing wire from both sides. The two ceramic electric heating plates 34 heat the passing wire, softening the rubber adhering to the outer surface of the wire. This softened rubber allows it to be more easily separated from the wire, facilitating subsequent scraping of the rubber adhering to the outer surface of the wire, thereby improving the efficiency of scraping the rubber adhering to the outer surface of the wire.

[0054] When the wire drawing hook 14 pulls the 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 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-type switch 37. During this process, the spring 1 381 is in a compressed state. When the wire drawing hook 14 is flush with the triangular block 39, the T-shaped rod 38 just contacts the push-type switch 37, thereby controlling the two electromagnets 310 to be energized by the push-type switch 37. When the electromagnets 310 are energized, the two electromagnets 310 drive the scraper 311 and the scraper mouth 312 to move vertically downward. During this process, the spring 2 313 is stretched, and the scraper mouth 312 eventually moves down to the path along which the wire is pulled, and the inner wall of the scraper mouth 312 contacts the outer wall of the wire. As the wire drawing hook 14 continues to move while pulling the wire, the softened rubber adhering to the outer surface of the wire is scraped off by the scraping action of the scraping mouth 312. When the outer wall of the wire drawing hook 14 no longer contacts the triangular block 39, the T-shaped rod 38 is reversely translated and reset under the rebound force of the spring 1 381. At this time, the T-shaped rod 38 does not control the two electromagnets 310 to be de-energized. In other words, the scraping mouth 312 continues to contact the outer surface of the wire, thereby continuously scraping off the rubber adhering to the outer surface of the wire.

[0055] Therefore, by setting up a coordinated scraping mechanism, when the steel wire is pulled out, the scraping mouth 312 is used to contact 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 adhering to the outer surface of the steel wire, thereby improving the comprehensive recycling efficiency of the steel wire.

The follow-up cutting mechanism includes a positioning frame 41 commonly fixedly connected between the two vertical plates 11. The positioning frame 41 is located on the side of the two vertical plates 11 close to the drive motor 24. A receiving barrel 42 is fixedly connected to the horizontal plate 12 and located on the side close to the positioning frame 41. A discharge pipe 43 is provided on one side of the receiving barrel 42. The discharge pipe 43 is arranged in an inclined manner. The 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 coaxial rod 44 and the vertical rod 46 are rotatably connected to the positioning frame 41. 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. The end of the coaxial rod 44 close to the vertical rod 46 is fixedly connected to a bevel gear 1 45. The lower end of the vertical rod 46 is fixedly connected to a bevel gear 2 47 that meshes 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. The cutter head 48 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 .

[0057] During use: The rubber scraped off by the scraping opening 312 will fall into the receiving barrel 42. After the steel wire of one scrap tire is removed, the next scrap tire undergoes rotational preheating. As the drive motor 24 drives the large gear 25, it also drives the coaxial rod 44 and bevel gear 1 45 to rotate synchronously. The rotation of bevel gear 1 45 then 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 via bevel gear 2 47. As the cutter head 48 rotates, its multiple circularly distributed blades cut the rubber that has fallen into the receiving barrel 42. The cut small rubber particles fall through the filter disc 49 into the bottom of the receiving barrel 42, while the remaining rubber continues to be cut within the receiving barrel 42. After the cut rubber particles fall to the bottom of the receiving barrel 42, the rotation of the vertical rod 46 also drives the synchronous rotation of the paddle 410, gradually pushing the rubber particles to the discharge pipe 43. The discharge pipe 43 is arranged at an angle, and the small rubber particles are automatically discharged outward under the action of gravity through the discharge pipe 43. The fallen rubber particles are then collected by an external container. The collected rubber particles are then processed through a specialized melting process and made into new rubber products.

[0058] 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.
