Description

Technical Field

[0001] This invention relates to the field of tire recycling technology, and in particular to a cleaning device for tire recycling based on the comprehensive utilization of solid waste. Background Technology

[0002] With the rapid development of the solid waste comprehensive utilization industry, waste tires, as a typical type of solid waste, have become an important measure for practicing the concept of green development and reducing resource waste and environmental pollution through recycling and reuse. During long-term use, waste tires accumulate a large amount of mud, oil, debris, and corrosive substances on their surface and in the tread grooves. If these contaminants are not thoroughly cleaned before entering the subsequent recycling process, they will not only severely wear down processing equipment such as crushing and screening machines, reducing their lifespan, but also affect the quality of recycled products such as recycled rubber and rubber granules, potentially even causing recycled products to fail to meet industry standards and limiting the resource utilization efficiency of waste tires. Therefore, the cleaning process before waste tire recycling is an indispensable key link in the comprehensive utilization of solid waste, and its cleaning effect directly determines the recycling value of waste tires and the smoothness of subsequent processing. Currently, various tire cleaning equipment has emerged in the industry for cleaning waste tires before recycling, but their overall structure and cleaning effect still have many shortcomings, making it difficult to meet the needs of large-scale, efficient, and refined cleaning.

[0003] Existing tire cleaning equipment suffers from the following drawbacks in practical applications, severely limiting cleaning efficiency and quality, and failing to fully meet the cleaning needs of waste tires in solid waste comprehensive utilization: First, the tread grooves are not thoroughly cleaned. Most existing equipment directly cleans the circular shape of the tire. Due to the narrow width of the tire tread grooves and the long-term adhesion of dirt to the inner wall of the grooves, the cleaning components cannot penetrate deep into the grooves, resulting in stubborn dirt not being effectively removed, thus affecting the quality of subsequent recycling. Second, the cleaning coverage is limited. Existing cleaning structures are mostly fixed flushing or friction structures, unable to follow the rotation or adjustment of the tire. The existing technology has several drawbacks. First, it can only clean localized areas of the tire surface, leaving obvious blind spots, especially in the tire tread area, resulting in poor cleaning performance. Second, it lacks automation; during the cleaning process, parameters such as the cleaning roller speed, cleaning fluid supply, and the adhesion force of the cleaning components are all fixed values, unable to adapt to the actual increase in tire tread size, dirt distribution, and severity. This not only leads to low cleaning efficiency but may also cause damage to the tire tread due to improper cleaning force, increasing the loss of used tires. Therefore, this invention proposes a tire cleaning device based on the comprehensive utilization of solid waste before recycling to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a cleaning device for tire recycling based on the comprehensive utilization of solid waste. This cleaning device effectively solves the problem of difficult-to-clean dirt in tire tread grooves, improving the thoroughness of cleaning. The tire is stably supported by support rollers on the base plate, and the tire is squeezed by a rotating arm driving a compression rod, compressing the originally round tire into an elliptical shape. After compression, the tread grooves at both ends of the tire enlarge, increasing the width of the originally narrow groove openings. This allows the cleaning components to smoothly penetrate into the grooves and fully contact the dirt on the inner wall of the grooves, thereby thoroughly cleaning stubborn debris such as mud and oil from the tread grooves. This prevents incomplete cleaning of the grooves from affecting the quality of subsequent recycling. Simultaneously, a limiting component restricts the tire, ensuring that it does not shift during the compression process, further improving the stability and thoroughness of cleaning, perfectly solving the shortcomings of incomplete cleaning of tire tread grooves in existing technologies.

[0005] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a cleaning device for tire recycling and processing based on the comprehensive utilization of solid waste, comprising a base plate, support rollers, and a support frame. The base plate has a bottom hole, and the support rollers are rotatably mounted on the base plate at both sides of the bottom hole. The support rollers are used to support the tire. The support frame is located at both ends of the top of the base plate, and the support frame has a panel. The panel has a cutout, and a rotating ring is rotatably mounted on the panel at the front side of the cutout. The rotating ring has a gap for the tire to pass through, and a cleaning component is mounted on the rotating ring. A tire-limiting component is mounted on the rear side of the top of the base plate.

[0006] The top front end of the base plate is equipped with a rotating arm, and one end of the rotating arm is equipped with a pressing rod. The pressing rod is used to press the tire into an elliptical shape, which makes the tread grooves at both ends of the tire larger, and works with the cleaning component to clean the dirt in the tread grooves.

[0007] A further improvement is that: support feet are provided at the four corners of the bottom of the base plate, and the support feet are integrally formed with the base plate.

[0008] A further improvement is that: a bearing seat is provided at the middle of both sides of the top of the base plate, and the support rollers on both sides are rotatably installed on the inner side of the bearing seat on both sides, and the support rollers are driven to rotate by a motor.

[0009] A further improvement is that: a support wheel is rotatably provided on the panel around the hollow front side, and multiple sets of support wheels are provided. The rotating disc is located inside the multiple sets of support wheels. Both ends of the upper front side of the panel are rotatably provided with drive wheels. The drive wheels are used to drive the rotating disc to rotate. The drive wheels are driven to rotate by a motor.

[0010] A further improvement is that a support plate is provided at one end of the top front side of the base plate, the rotating arm is rotatably mounted on the support plate, and a cylinder is hinged to the lower part of one end of the front side of the support frame, with the output end of the cylinder hinged to the lower end of the rotating arm.

[0011] A further improvement is that the limiting component includes a mounting frame and a guide rod. The mounting frame is located on the rear side of the top of the base plate, and the guide rod is located above and below the inner side of the mounting frame. Movable arms are provided on both sides of the guide rod, and limiting rollers are rotatably provided at the upper and lower ends of the front side of the moving arms. The limiting rollers on both sides are used to clamp and limit the tire.

[0012] A further improvement is that a bidirectional threaded screw is rotatably provided at the middle position inside the mounting bracket, and the threads at both ends of the bidirectional threaded screw pass through the two sets of moving arms and are threadedly matched. One end of the bidirectional threaded screw is connected to a handle.

[0013] A further improvement is that the cleaning assembly includes an electric telescopic rod and a U-shaped frame. The electric telescopic rod is mounted on a rotating ring, and the U-shaped frame is mounted on the output end of the electric telescopic rod. A cleaning roller is rotatably mounted on the inner side of the U-shaped frame, and the cleaning roller is driven to rotate by a reduction motor.

[0014] A further improvement is that the cleaning roller includes a hollow roller body and a sponge sleeve. The sponge sleeve is fitted on the outside of the hollow roller body, and the surface of the hollow roller body is provided with water outlet holes. The sponge sleeve is provided with a water outlet channel that communicates with the water outlet holes. One end of the hollow roller body is connected to a water guide pipe through a sealed bearing, and the water guide pipe is used to connect to the cleaning liquid tank.

[0015] A further improvement is made in that: the panel is equipped with a camera to collect tire tread data. After the extrusion rod squeezes the tire to enlarge the tread grooves at both ends, based on the data collected by the camera, a collaborative algorithm of intelligent tread recognition and precise cleaning is used to adjust the working parameters of the cleaning components in a coordinated manner, so as to achieve precise cleaning of the enlarged tread grooves, as detailed below:

[0016] Formula for determining tread width: W≥1.5W0,

[0017] The formula for the real-time rotational speed of the cleaning roller is: V = V0 + ΔV, where ΔV = (D0 - D)·k.

[0018] The formula for real-time supply of cleaning solution is: Q = Q0 + ΔQ, where ΔQ = ΔV·0.3.

[0019] Extrusion stroke determination formula: L≥Lmin,

[0020] Cleaning effectiveness judgment formula: F≥F0,

[0021] Wherein, W is the real-time opening width of the tread grooves at both ends of the tire after compression, in mm, calculated from the tread contour feature matrix M, reflecting the actual size of the tread after enlargement, and is one of the core judgment parameters for starting precise cleaning; W0 is the initial opening width of the tread grooves at both ends of the tire before compression, in mm, calculated from the initial tread image C0 before compression, serving as the benchmark value for whether the tread has effectively enlarged; V is the real-time rotational speed of the cleaning roller, in r / min, adjusted by the reduction motor, dynamically changing according to the degree of dirt to determine the cleaning force; V0 is the benchmark rotational speed of the cleaning roller, in r / min, with a preset range of 180-220 r / min, representing the initial working speed of the cleaning roller to avoid... Excessive initial speed can damage tire treads; △V is the speed adjustment amount of the cleaning roller, in r / min, dynamically calculated based on the severity of dirt to adapt to different levels of dirt; D is the dirt characteristic value in the tread groove, unitless, ranging from 0-255, representing the average grayscale value of the tread groove area, extracted from the grayscale processing of the real-time tread image C after extrusion. The smaller the value, the more severe the dirt; D0 is the dirt judgment threshold, unitless, with a preset value of 85, which is the critical value for distinguishing whether there is dirt in the tread groove and is used to determine whether cleaning needs to be started; k is the speed adjustment coefficient, unitless, ranging from 0.8-1.2, preset based on the tire tread depth. The deeper the tread, the larger the coefficient, ensuring that the cleaning force is appropriate for the tread depth. The cleaning fluid supply is adjusted according to the following parameters: Q is the real-time supply volume of cleaning fluid, measured in mL / min, controlled by a flow valve on the water pipe and linked to the cleaning roller speed to ensure that the cleaning fluid supply matches the cleaning force; Q0 is the baseline supply volume of cleaning fluid, measured in mL / min, with a preset range of 60-90 mL / min, serving as the basic supply volume to avoid waste or insufficient supply; △Q is the adjustment amount of cleaning fluid supply, measured in mL / min, which changes synchronously with the cleaning roller speed adjustment (DeltaV) to ensure that the cleaning fluid fully soaks the sponge sleeve, improving the dirt removal effect; L is the real-time extrusion stroke of the extrusion rod, measured in mm, collected by a displacement sensor built into the cylinder, reflecting the degree of tire compression and determining the tread depth. Key parameters for determining whether the tire tread has reached an effective enlargement state: Lmin: Minimum effective extrusion stroke of the extrusion rod, unit: mm, preset value is 10mm. When the extrusion stroke reaches this value, it is determined that the tire tread has initially enlarged, and the tire tread recognition process can be started; F: Cleaning effect feedback value, no unit, value range 0-1, calculated from the tire tread image after secondary acquisition by the camera, used to quantify the cleaning effect; F0: Cleaning effect compliance threshold, no unit, preset value is 0.9, which is the critical value for determining whether the cleaning of dirt in the tire tread groove has met the standard. When the cleaning effect feedback value reaches this threshold, the cleaning of this area is stopped; After initializing the parameters, the extrusion rod extrudes the tire, and extrusion stops when L≥Lmin; The tire tread image after extrusion is acquired, and W is calculated. If W≥1...If 5W0, then extract D. When D < D0, calculate V and Q using the above formula, and adjust the cleaning components for cleaning. Real-time acquisition of post-cleaning images calculates F. If F ≥ F0, cleaning is considered successful; otherwise, fine-tune parameters and re-scan until all enlarged tire tread grooves are cleaned.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention effectively solves the problem of difficult cleaning of tire tread grooves, improving the thoroughness of cleaning. The tire is stably supported by support rollers on the base plate, and the tire is squeezed by a rotating arm driving a compression rod, causing the originally round tire to be compressed into an elliptical shape. After compression, the tire tread grooves at both ends enlarge, increasing the width of the originally narrow groove openings. This allows the cleaning components to easily penetrate into the grooves and fully contact the dirt on the inner wall of the grooves, thus thoroughly cleaning stubborn debris such as mud and oil from the tire tread grooves. This prevents incomplete cleaning of the grooves from affecting the quality of subsequent recycling. Simultaneously, a limiting component restricts the tire's movement during compression, further improving the stability and thoroughness of cleaning, perfectly solving the shortcomings of incomplete cleaning of tire tread grooves in existing technologies.

[0024] 2. This invention employs a rotary cleaning structure, expanding the cleaning coverage area, eliminating cleaning dead angles, and improving the overall cleaning effectiveness. The device features a rotating ring mounted on a panel on a support frame, supported by support wheels and driven by a drive wheel. The cleaning components are fixedly mounted on the rotating ring and rotate synchronously with it. Simultaneously, the cleaning roller itself can be driven to rotate by a reduction motor, forming a dual rotary cleaning structure of overall ring rotation + cleaning roller rotation. This structure allows the cleaning components to perform all-around cleaning around the tire circumference, especially targeting areas where tire tread grooves have enlarged after compression, achieving comprehensive coverage without dead angles. Furthermore, the electric telescopic rod can adjust the position of the cleaning roller, ensuring precise contact with the tire surface and tread grooves. This overcomes the shortcomings of existing technologies, such as fixed cleaning structures, limited cleaning coverage, and the presence of cleaning dead angles, significantly improving the comprehensiveness and uniformity of tire cleaning.

[0025] 3. This invention introduces an intelligent control algorithm to enhance the intelligence of the equipment, achieving precise and efficient cleaning while reducing tire wear: By capturing images of the tire tread after compression using a camera and combining this with data on the compression stroke of the compression rod, parameters such as the tread opening width and dirt characteristic values ​​are calculated in real time. This allows for adaptive adjustment of the cleaning roller's rotation speed, cleaning fluid supply, and the extension / retraction of the electric telescopic rod, achieving closed-loop control of compression-identification-cleaning-feedback. This dynamically adjusts cleaning parameters based on the degree of tread enlargement, dirt distribution, and severity, avoiding the problems of low cleaning efficiency and tire damage caused by fixed cleaning parameters in existing technologies. It ensures thorough dirt removal while avoiding ineffective contact between the cleaning components and non-tread areas of the tire, reducing tire wear, improving cleaning efficiency, reducing manual labor intensity, and adapting to the needs of large-scale waste tire cleaning.

[0032] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0033] Example 1

[0034] according to Figure 1 , 2As shown in Figures 3, 4, and 5, this embodiment proposes a cleaning device for tire recycling based on the comprehensive utilization of solid waste. The device includes a base plate 1, support rollers 2, and a support frame 3. The base plate 1 has a bottom hole, and the support rollers 2 are rotatably mounted on both sides of the bottom hole. The support rollers 2 support the tires. The support frame 3 is located at both ends of the top of the base plate 1, and a panel 4 is mounted on the support frame 3. The panel 4 has a perforation, and a rotating ring 5 is rotatably mounted on the front side of the perforation. The rotating ring 5 has a gap for the tire to pass through, and a cleaning component is mounted on the rotating ring 5. A tire-limiting component is located on the rear side of the top of the base plate 1. The base plate 1 serves as the mounting foundation for the device. All components provide stable support. The bottom hole is used to drain the sewage and debris generated during the cleaning process to prevent sewage accumulation from affecting the cleaning effect. The support roller 2 is rotatably mounted on the base plate 1 to support the tire to be cleaned and drive the tire to rotate, which facilitates subsequent squeezing and cleaning operations. The support frame 3 is fixed at both ends of the top of the base plate 1 to install and fix the panel 4. The cutout on the panel 4 is for the tire to pass through, so that the tire can pass through the equipment for comprehensive cleaning. The rotating ring 5 is rotatably mounted on the front side of the cutout on the panel 4, which can drive the cleaning components on it to rotate around the tire to achieve all-round cleaning of the tire. The limiting component is used to limit and fix the tire to prevent the tire from shifting during squeezing and cleaning, and to ensure operational stability.

[0035] A rotating arm 6 is rotatably mounted on the front top of the base plate 1, and a pressing rod 7 is mounted on one end of the rotating arm 6. The pressing rod 7 is used to compress the tire into an elliptical shape, thereby enlarging the tread grooves at both ends of the tire. This allows the cleaning component to clean the dirt inside the tread grooves. The rotating arm 6 is rotatably mounted on the front top of the base plate 1 and can rotate around the mounting point. The pressing rod 7 is fixed to one end of the rotating arm 6. When the rotating arm 6 rotates, the pressing rod 7 can move towards the tire and compress the tire, squeezing the originally round tire into an elliptical shape. After the tire is compressed, the tread grooves at both ends will enlarge due to the change in shape. The width of the originally narrow groove opening increases, thereby providing sufficient operating space for the cleaning component. This allows the cleaning component to easily penetrate into the grooves and thoroughly clean the dirt inside, solving the problem of difficult cleaning of tread grooves in traditional cleaning methods.

[0036] Support feet 8 are provided at each of the four corners of the bottom of the base plate 1, and the support feet 8 are integrally formed with the base plate 1. The support feet 8 are located at the four corners of the bottom of the base plate 1 and are integrally formed with the base plate 1, which can enhance the connection strength between the support feet 8 and the base plate 1, prevent the support feet 8 from falling off, and at the same time, the four support feet 8 work together to support the entire equipment, keeping the base plate 1 at a certain distance from the ground. This not only prevents sewage and debris from the ground from contaminating the base plate 1 and the internal components of the equipment, but also ensures the stability of the equipment and prevents the equipment from shaking during operation, which would affect the squeezing and cleaning effect.

[0037] The base plate 1 has a bearing seat 9 at the middle of both sides of its top. The support rollers 2 on both sides are rotatably mounted on the inner side of the bearing seats 9, and the support rollers 2 are driven to rotate by a motor. The bearing seats 9 are fixed at the middle of both sides of the top of the base plate 1 to install the support rollers 2, providing a stable rotation support point for the support rollers 2 and ensuring that the support rollers 2 can rotate smoothly. The motor provides power for the rotation of the support rollers 2, driving the support rollers 2 to rotate at a uniform speed. When the support rollers 2 rotate, they can drive the tires on them to rotate synchronously, so that all parts of the tires can be covered by the cleaning components, achieving comprehensive cleaning of the tires. At the same time, the rotation of the tires can also cooperate with the squeezing of the extrusion rod 7 to make the tread grooves uniformly enlarged.

[0038] Support wheels 10 are rotatably mounted on the panel 4 around the hollowed-out front side, and multiple sets of support wheels 10 are provided. The rotating ring 5 is rotatably mounted inside the multiple sets of support wheels 10. Drive wheels 11 are rotatably mounted at both ends of the upper front side of the panel 4. The drive wheels 11 are used to drive the rotating ring 5 to rotate, and the drive wheels 11 are driven to rotate by a motor. The multiple sets of support wheels 10 are rotatably mounted around the hollowed-out front side of the panel 4 to support the rotating ring 5, reduce the friction between the rotating ring 5 and the panel 4 when it rotates, and enable the rotating ring 5 to rotate smoothly and stably. The motor provides power to the drive wheels 11. When the drive wheels 11 rotate, they contact the rotating ring 5 and drive the rotating ring 5 to rotate synchronously through friction. When the rotating ring 5 rotates, it drives the cleaning components on it to move around the circumference of the tire, realizing thorough cleaning of all parts of the tire and improving the comprehensiveness of cleaning.

[0039] A support plate 12 is provided at one end of the top front side of the base plate 1. The rotating arm 6 is rotatably mounted on the support plate 12. A cylinder 13 is hinged to the lower part of the front end of the support frame 3. The output end of the cylinder 13 is hinged to the lower end of the rotating arm 6. The support plate 12 is fixed at one end of the top front side of the base plate 1, providing a stable rotation mounting point for the rotating arm 6, ensuring that the rotating arm 6 can rotate flexibly around the support plate 12. The cylinder 13 is hinged to the lower part of the front end of the support frame 3, and its output end is hinged to the lower end of the rotating arm 6. The cylinder 13 serves as a power source, driving the rotating arm 6 to rotate around the support plate 12 through telescopic movement, thereby driving the compression rod 7 to move or reset towards the tire, realizing the compression and release operation of the tire. The telescopic force of the cylinder 13 is adjustable, which can adapt to tires of different specifications and hardness, avoiding excessive compression force that damages the tire or insufficient compression force that causes the tire tread grooves to become larger and less obvious.

[0040] The limiting assembly includes a mounting frame 14 and a guide rod 15. The mounting frame 14 is located on the rear side of the top of the base plate 1. The guide rod 15 is located above and below the inner side of the mounting frame 14. Movable arms 16 are provided on both sides of the guide rod 15, and limiting rollers 17 are rotatably provided at the upper and lower ends of the front side of the moving arms 16. The limiting rollers 17 on both sides are used to clamp and limit the tire. Mounting bracket 14 is fixed to the top rear side of base plate 1, serving as the mounting base for the limiting component. Guide rod 15 is fixed to the upper and lower sides of the inner side of mounting bracket 14, providing guidance for the moving arm 16, enabling the moving arm 16 to move horizontally along the guide rod 15. The moving arm 16 is movably mounted on the guide rod 15, and the limiting roller 17 is rotatably mounted on the upper and lower ends of the front side of the moving arm 16. When the two sets of moving arms 16 move relative to each other along the guide rod 15, they can drive the limiting roller 17 on both sides to move closer or further away from each other, thereby clamping or releasing the tire, achieving the limiting and fixing of the tire, and preventing the tire from shifting left or right or sliding back and forth during the squeezing and cleaning process. The limiting roller 17 can rotate, which can cooperate with the rotation of the tire to avoid wear on the tire surface during limiting.

[0041] A bidirectional threaded screw 18 is rotatably mounted at the middle position inside the mounting frame 14. The threads at both ends of the bidirectional threaded screw 18 pass through and are threadedly fitted to the two sets of moving arms 16. One end of the bidirectional threaded screw 18 is connected to a handle 19. The bidirectional threaded screw 18 is rotatably mounted at the middle position inside the mounting frame 14, with threads at both ends having opposite directions of rotation, respectively threadedly fitted to the two sets of moving arms 16. The handle 19 is fixed to one end of the bidirectional threaded screw 18. When the operator rotates the handle 19, the bidirectional threaded screw 18 rotates. Because the threads at both ends of the bidirectional threaded screw 18 have opposite directions of rotation, the two sets of moving arms 16 move synchronously closer or further apart along the guide rod 15, thereby adjusting the distance between the two limiting rollers 17, adapting to tires of different diameters, and achieving stable limiting of tires of different specifications. The operation is simple and convenient, requiring no additional power source.

[0042] Example 2

[0043] according to Figure 1 , 2As shown in Figures 3, 4, and 5, this embodiment proposes a cleaning device for tire recycling based on the comprehensive utilization of solid waste. The device includes a base plate 1, support rollers 2, and a support frame 3. The base plate 1 has a bottom hole, and the support rollers 2 are rotatably mounted on both sides of the bottom hole. The support rollers 2 support the tires. The support frame 3 is located at both ends of the top of the base plate 1, and a panel 4 is mounted on the support frame 3. The panel 4 has a perforation, and a rotating ring 5 is rotatably mounted on the front side of the perforation. The rotating ring 5 has a gap for the tire to pass through, and a cleaning component is mounted on the rotating ring 5. A tire-limiting component is located on the rear side of the top of the base plate 1. The base plate 1 serves as the mounting foundation for the device. All components provide stable support. The bottom hole is used to drain the sewage and debris generated during the cleaning process to prevent sewage accumulation from affecting the cleaning effect. The support roller 2 is rotatably mounted on the base plate 1 to support the tire to be cleaned and drive the tire to rotate, which facilitates subsequent squeezing and cleaning operations. The support frame 3 is fixed at both ends of the top of the base plate 1 to install and fix the panel 4. The cutout on the panel 4 is for the tire to pass through, so that the tire can pass through the equipment for comprehensive cleaning. The rotating ring 5 is rotatably mounted on the front side of the cutout on the panel 4, which can drive the cleaning components on it to rotate around the tire to achieve all-round cleaning of the tire. The limiting component is used to limit and fix the tire to prevent the tire from shifting during squeezing and cleaning, and to ensure operational stability.

[0044] A rotating arm 6 is rotatably mounted on the front top of the base plate 1, and a pressing rod 7 is mounted on one end of the rotating arm 6. The pressing rod 7 is used to compress the tire into an elliptical shape, thereby enlarging the tread grooves at both ends of the tire. This allows the cleaning component to clean the dirt inside the tread grooves. The rotating arm 6 is rotatably mounted on the front top of the base plate 1 and can rotate around the mounting point. The pressing rod 7 is fixed to one end of the rotating arm 6. When the rotating arm 6 rotates, the pressing rod 7 can move towards the tire and compress the tire, squeezing the originally round tire into an elliptical shape. After the tire is compressed, the tread grooves at both ends will enlarge due to the change in shape. The width of the originally narrow groove opening increases, thereby providing sufficient operating space for the cleaning component. This allows the cleaning component to easily penetrate into the grooves and thoroughly clean the dirt inside, solving the problem of difficult cleaning of tread grooves in traditional cleaning methods.

[0045] The cleaning assembly includes an electric telescopic rod 20 and a U-shaped frame 21. The electric telescopic rod 20 is mounted on a rotating ring 5, and the U-shaped frame 21 is located at the output end of the electric telescopic rod 20. A cleaning roller 22 is rotatably mounted on the inner side of the U-shaped frame 21, and the cleaning roller 22 is driven to rotate by a reduction motor. The electric telescopic rod 20 is fixed on the rotating ring 5 and can rotate synchronously with the rotating ring 5. The electric telescopic rod 20 drives the U-shaped frame 21 and the cleaning roller 22 to move back and forth through its telescopic movement, adjusting the contact force between the cleaning roller 22 and the tire surface, so that the cleaning roller 22 can closely fit the tire surface and tread grooves, improving the cleaning effect. The U-shaped frame 21 is used to install the cleaning roller 22 and provide stable rotational support for the cleaning roller 22. The reduction motor provides power for the rotation of the cleaning roller 22, driving the cleaning roller 22 to rotate at a uniform speed. When the cleaning roller 22 rotates, it contacts the tire surface and tread grooves, and removes dirt from the tire surface and grooves through friction, thus achieving the cleaning function. The reduction motor can adjust the speed of the cleaning roller 22 to adapt to different cleaning needs of different levels of dirt.

[0046] The cleaning roller 22 includes a hollow roller body 24 and a sponge sleeve 25. The sponge sleeve 25 is sleeved on the outside of the hollow roller body 24, and the surface of the hollow roller body 24 is provided with water outlet holes 26. The sponge sleeve 25 is provided with a water outlet channel that communicates with the water outlet holes 26. One end of the hollow roller body 24 is connected to a water guide pipe 23 through a sealed bearing, and the water guide pipe 23 is used to connect to the cleaning liquid tank. The water guide pipe 23 connects to the cleaning fluid tank and is used to deliver the cleaning fluid to the interior of the hollow roller body 24. The sealed bearing prevents the cleaning fluid from leaking from the connection between the hollow roller body 24 and the water guide pipe 23. The water outlet hole 26 on the surface of the hollow roller body 24 is connected to the water outlet channel on the sponge sleeve 25. After the cleaning fluid enters the hollow roller body 24, it penetrates into the sponge sleeve 25 through the water outlet hole 26 and the water outlet channel, so that the sponge sleeve 25 is fully soaked with the cleaning fluid, which enhances the dirt removal ability of the cleaning roller 22. At the same time, the cleaning fluid can soften the stubborn dirt in the tire tread grooves, making it easier for the cleaning roller 22 to clean it. The sponge sleeve 25 is soft in texture, which can avoid damaging the tire tread during the cleaning process, and can conform to the shape of the tire tread grooves to improve the thoroughness of cleaning.

[0047] The panel is equipped with a camera that collects tire tread data. After the extrusion rod 7 extrudes the tire, enlarging the tread grooves at both ends, the cleaning components' working parameters are adjusted in conjunction with the data collected by the camera, using a tread intelligent recognition and precise cleaning collaborative algorithm, to achieve precise cleaning of the enlarged tread grooves. The specific details are as follows:

[0048] Formula for determining tread width: W≥1.5W0,

[0049] The formula for the real-time rotational speed of the cleaning roller is: V = V0 + ΔV, where ΔV = (D0 - D)·k.

[0050] The formula for real-time supply of cleaning solution is: Q = Q0 + ΔQ, where ΔQ = ΔV·0.3.

[0051] Extrusion stroke determination formula: L≥Lmin,

[0052] Cleaning effectiveness judgment formula: F≥F0,

[0053] Wherein, W is the real-time opening width of the tread grooves at both ends of the tire after compression, in mm, calculated from the tread contour feature matrix M, reflecting the actual size of the tread after enlargement, and is one of the core judgment parameters for starting precise cleaning; W0 is the initial opening width of the tread grooves at both ends of the tire before compression, in mm, calculated from the initial tread image C0 before compression, serving as the benchmark value for whether the tread has effectively enlarged; V is the real-time rotational speed of the cleaning roller 22, in r / min, adjusted by the reduction motor, dynamically changing according to the degree of dirt to determine the cleaning force; V0 is the benchmark rotational speed of the cleaning roller 22, in r / min, with a preset range of 180-220 r / min, which is the initial working speed of the cleaning roller, avoiding... Excessive initial speed can damage tire treads; △V is the speed adjustment amount of cleaning roller 22, in r / min, dynamically calculated based on the severity of dirt to adapt to different levels of dirt; D is the dirt characteristic value in the tread groove, unitless, ranging from 0-255, representing the average grayscale value of the tread groove area, extracted from the grayscale processing of the real-time tread image C after extrusion. The smaller the value, the more severe the dirt; D0 is the dirt judgment threshold, unitless, with a preset value of 85, which is the critical value for distinguishing whether there is dirt in the tread groove and is used to determine whether cleaning needs to be started; k is the speed adjustment coefficient, unitless, ranging from 0.8-1.2, preset based on the tire tread depth. The deeper the tread, the larger the coefficient, ensuring that the cleaning force is appropriate for the tread depth. Q represents the real-time supply of cleaning fluid, in mL / min, controlled by the flow valve on the water guide pipe 23 and linked to the cleaning roller speed to ensure that the cleaning fluid supply matches the cleaning force; Q0 represents the baseline supply of cleaning fluid, in mL / min, with a preset range of 60-90 mL / min, serving as the basic supply to avoid waste or insufficient supply; △Q represents the cleaning fluid supply adjustment, in mL / min, which changes synchronously with the cleaning roller speed adjustment (DeltaV) to ensure that the cleaning fluid fully soaks the sponge sleeve 25, improving the dirt removal effect; L represents the real-time extrusion stroke of the extrusion rod 7, in mm, collected by the displacement sensor built into the cylinder 13, reflecting the degree of tire compression and used to determine the tire pressure. Key parameters for determining whether the tread pattern has reached an effective enlargement state; Lmin: Minimum effective extrusion stroke of the extrusion rod 7, unit: mm, preset value is 10mm. When the extrusion stroke reaches this value, it is determined that the tread pattern has initially enlarged, and the tread pattern recognition process can be started; F: Cleaning effect feedback value, no unit, value range 0-1, calculated from the tread pattern image after secondary acquisition by the camera, used to quantify the cleaning effect; F0: Cleaning effect compliance threshold, no unit, preset value is 0.9, which is the critical value for determining whether the dirt in the tread groove has been cleaned up to standard. When the cleaning effect feedback value reaches this threshold, the cleaning of this area is stopped; After initializing the parameters, the extrusion rod 7 extrudes the tire, and extrusion stops when L≥Lmin; Acquire the tread pattern image after extrusion, calculate W, if W≥1.If 5W0, then extract D. When D < D0, calculate V and Q using the above formula, and adjust the cleaning components to perform cleaning. Collect images after cleaning in real time to calculate F. When F ≥ F0, the cleaning is up to standard; otherwise, fine-tune the parameters and re-sweep until all enlarged tire tread grooves are cleaned. A camera, fixed to panel 4, is used to collect real-time images of the tire tread before and after compression, providing basic data for the algorithm. The displacement sensor built into cylinder 13 calculates and collects the real-time compression stroke L of the compression rod 7, providing feedback on the degree of tire compression. The algorithm preprocesses and extracts features from the images collected by the camera, calculating parameters such as W and D. Combined with preset thresholds and formulas, it dynamically adjusts the rotational speed V of the cleaning roller 22, the cleaning fluid supply Q, and the extension / retraction of the electric telescopic rod 20, achieving closed-loop control of "compression-recognition-cleaning-feedback". When the compression rod 7 compresses the tire to L≥Lmin, the algorithm initiates tread recognition. If W≥1.5W0 and D<D0, the cleaning component parameters are adjusted for precise cleaning. The camera collects images after cleaning in real-time to calculate F until F≥F0, completing the cleaning process. This ensures cleaning effectiveness while preventing damage to the tire from the cleaning components, improving cleaning efficiency and intelligence.

[0054] This tire recycling and pre-processing cleaning equipment based on the comprehensive utilization of solid waste effectively solves the problem of difficult-to-clean tire tread grooves, improving the thoroughness of cleaning. The tire is stably supported by the support rollers 2 on the base plate 1, and the rotating arm 6 drives the extrusion rod 7 to squeeze the tire, compressing the originally round tire into an elliptical shape. After the tire is squeezed, the tread grooves at both ends of the tire will become larger, and the width of the originally narrow groove opening will increase, allowing the cleaning components to smoothly penetrate into the groove and fully contact the dirt on the inner wall of the groove, thereby thoroughly cleaning the stubborn debris such as mud and oil in the tread groove. This avoids the impact of incomplete cleaning of the grooves on the quality of subsequent recycling and processing. At the same time, the limiting components limit the tire to ensure that the tire does not shift during the extrusion process, further improving the stability and thoroughness of cleaning, and perfectly solving the shortcomings of incomplete cleaning of tire tread grooves in existing technologies. Furthermore, it adopts a rotary cleaning structure to expand the cleaning coverage area, eliminate cleaning dead corners, and improve the overall cleaning effect. The equipment is mounted on a rotating ring 5 via a panel 4 on a support frame 3. The rotating ring 5 is supported by a support wheel 10 and driven to rotate by a drive wheel 11. The cleaning components (electric telescopic rod 20, U-shaped frame 21, and cleaning roller 22) are fixedly mounted on the rotating ring 5 and can rotate synchronously with the rotating ring 5. At the same time, the cleaning roller 22 itself can be driven to rotate by a reduction motor, forming a dual rotary cleaning structure of overall rotation of the rotating ring + rotation of the cleaning roller itself. This structure can drive the cleaning components to perform all-round cleaning around the tire circumference, especially for areas where the tire tread grooves have enlarged after compression, achieving coverage without dead corners. Meanwhile, the electric telescopic rod 20 can adjust the position of the cleaning roller 22 to precisely fit the tire surface and tread grooves, solving the shortcomings of existing technologies such as fixed cleaning structure, limited cleaning coverage area, and the existence of cleaning dead corners, and greatly improving the comprehensiveness and uniformity of tire cleaning. Colleagues introduced intelligent control algorithms to enhance the equipment's intelligence, achieving precise and efficient cleaning while reducing tire wear: By capturing images of the tire tread after compression using a camera, and combining this with the compression stroke data of the compression rod 7, parameters such as the tread opening width and dirt characteristic values ​​are calculated in real time. This allows for adaptive adjustment of the rotation speed of the cleaning roller 22, the supply of cleaning fluid (controlled by a pump connected to the water pipe 23), and the extension of the electric telescopic rod 20. This achieves closed-loop control of compression-identification-cleaning-feedback, dynamically adjusting cleaning parameters based on the degree of tread enlargement and the distribution and severity of dirt. This avoids the problems of low cleaning efficiency and tire damage caused by fixed cleaning parameters in existing technologies. It ensures thorough cleaning of dirt while avoiding ineffective contact between the cleaning components and non-tread areas of the tire, reducing tire wear, improving cleaning efficiency, reducing manual labor intensity, and adapting to the needs of large-scale waste tire cleaning.
