Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tire processing, and in particular to a pretreatment device for recycling waste materials from aircraft tire processing. Background Technology
[0002] During the manufacturing process of aircraft tires, some scrap materials are generated. These scrap materials are recycled, pre-treated by crushing, and then reused in production. Chinese utility model patent CN220091527U discloses a tire crushing device. This device includes a crushing chamber. Unqualified tire fragments are filtered out by a filter plate and then fed into a conveying pipe through a feeding pipe. A third motor, rotating rods, and spiral crushing blades work together to transport the unqualified tire fragments, which are then discharged through the feeding pipe into the crushing chamber for further crushing, thus improving the crushing quality. A conveying assembly is also included. By placing the tire on the surface of a conveyor belt, the output shaft of a first motor drives one set of conveyor rods to rotate. This set of conveyor rods drives a transmission belt and another set of conveyor rods to rotate, conveying the tire onto the conveyor belt. Upon reaching the top of the conveyor belt, the tire falls into the crushing chamber under the influence of inertia and gravity for further crushing.
[0003] However, the above-mentioned crushing device requires multiple drive motors and uses a screw conveyor mechanism to circulate and crush the residue, resulting in high energy consumption. Moreover, the residue flows along the inclined surface of the inclined block after crushing and is discharged, resulting in low discharge efficiency. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a pretreatment device for recycling aircraft tire processing waste materials that can circulate and crush aircraft tire waste materials, with lower energy consumption, simple structure, and high discharge efficiency.
[0005] This utility model discloses a pretreatment device for recycling waste materials from aviation tire processing. It includes a base plate, a left column, a left roller, a middle column, a middle roller, a right roller frame, a right roller, a conveyor belt, and a cutter roller. The left column is installed on the left side of the base plate, and the left roller is rotatably mounted on the left column. The middle column is installed in the middle of the base plate, and the middle roller is rotatably mounted on the middle column. The lower end of the right roller frame is mounted on the middle column, and the right roller is rotatably mounted on the upper end of the right roller frame. The middle roller is lower than the left and right rollers. The two ends of the conveyor belt are fitted onto the left and right rollers, with the middle roller located in the middle of the conveyor belt. The middle roller provides downward support to the lower middle layer of the conveyor belt, making it V-shaped. The cutter roller is rotatably mounted on the middle column, and multiple cutter discs are concentrically mounted on the cutter roller, pressing the upper middle layer of the conveyor belt against the middle roller. The left, middle, and right rollers provide rolling support for the conveyor belt, which can be made of metal. The conveyor belt is made of woven wire. Waste materials from aircraft tires are fed onto its upper surface. Due to the V-shape of the conveyor belt, the waste materials converge towards the cutter roller. The left roller, driven by a motor, reciprocates, causing the conveyor belt to rotate reciprocally. The conveyor belt carries the waste materials, moving them back and forth beneath multiple cutter discs on the cutter roller. This allows the cutter discs and the conveyor belt to perform a pre-treatment of cutting and pulverizing the waste materials. After the waste materials are cut and pulverized, the left roller drives the conveyor belt to continue rotating, transporting the powdered waste materials to the right end and outputting them to the outlet. Compared to existing technologies, this method only requires one drive motor to achieve the cyclic pulverization of waste materials, resulting in lower energy consumption, a simpler structure, and efficient active discharge of waste materials.
[0006] Preferably, it also includes a lower shaft seat, a push cylinder, and an ear plate. The lower end of the right roller frame is rotatably connected to the central column. The lower shaft seat is mounted on the base plate. The fixed end of the push cylinder is rotatably connected to the lower shaft seat. An ear plate is installed at the end of the piston rod of the push cylinder. The ear plate is rotatably connected to the right roller frame. The piston rod of the push cylinder extends and pushes the upper end of the right roller frame upward through the ear plate, so that the upper end of the right roller frame drives the right roller to be higher than the middle roller, making the conveyor belt V-shaped, which facilitates the crushing of aircraft tire waste. After the aircraft tire waste is crushed, the right roller frame drives the right roller to descend to be flush with or slightly lower than the middle roller, so that the right end of the conveyor belt is flat or tilted downward, thereby improving the discharge efficiency of aircraft tire waste.
[0007] Preferably, the assembly also includes a slider, a threaded sleeve, and a screw. The slider is installed at the end of the cutter roller and is slidably installed in the vertical groove of the central column. The threaded sleeve is installed at the top of the central column. The lower end of the screw is rotatably connected to the slider, and the screw and the threaded sleeve are rotatably screwed together. Rotating the screw causes the screw and the threaded sleeve to engage, thereby driving the slider to rise and fall along the vertical groove of the central column, thus adjusting the height of the cutter roller and the gap between the cutter roller and the conveyor belt, achieving different crushing effects on the waste materials from aircraft tires.
[0008] Preferably, it also includes a crossbeam and multiple paddles. The crossbeam is mounted on the central column, and multiple paddles are installed on both the left and right sides of the crossbeam. The lower ends of the multiple paddles extend into the space between the cutting edges of the multiple cutter discs of the cutter roller. When the multiple cutter discs of the cutter roller crush the aircraft tire scraps, the multiple paddles will push out the fragments of aircraft tire scraps that are clamped between the cutting edges of the cutter discs, thereby improving the cutting efficiency of the cutter discs of the cutter roller.
[0009] Preferably, it also includes side panels, with side panels installed on both sides of the conveyor belt; by installing side panels on the edges of the conveyor belt, the residual aircraft tire material on the conveyor belt is restrained, reducing the amount of residual aircraft tire material falling off.
[0010] Preferably, it also includes a left scraper, which is mounted on the left column. The lower edge of the left scraper is in frictional contact with the outer surface of the upper left layer of the conveyor belt. The left scraper scrapes off the residual aircraft tire material on the surface of the conveyor belt, so that the scraped-off residual aircraft tire material flows back to the cutter roller for recycling and cutting.
[0011] Preferably, the assembly also includes a rotating shaft, gear one, gear two, and a right scraper. The rotating shaft is rotatably mounted on the right roller frame. Gear one is concentrically mounted on the rotating shaft, and gear two is mounted on an ear plate, meshing with gear one. The right scraper is mounted on the rotating shaft, and its lower end is in frictional contact with the outer surface of the upper right section of the conveyor belt. When the piston rod of the push cylinder extends and pushes the right roller frame to stand upright, the ear plate drives gear two to rotate relative to the right roller frame, thereby causing gear two to mesh with gear one and drive the rotating shaft to rotate. This causes the rotating shaft to adjust the angle of the right scraper, so that the lower end of the right scraper is in frictional contact with the outer surface of the upper right section of the conveyor belt. The surface friction contact causes the right scraper to scrape off the excess aviation tire material from the conveyor belt surface, allowing the scraped material to flow back to the cutter roller for repeated cutting. When the piston rod of the push cylinder retracts and drives the right roller frame to level, the ear plate drives gear two to rotate in the opposite direction to the right roller frame. This causes gear two to mesh with gear one, driving the rotating shaft to rotate in the opposite direction. The rotating shaft then drives the right scraper to adjust its angle in the opposite direction, causing the lower end of the right scraper to disengage from the outer surface of the upper right side of the conveyor belt. This allows the excess aviation tire material to be discharged through the gap between the right scraper and the conveyor belt, improving the material discharge efficiency.
[0012] Compared with the prior art, the advantages of this utility model are: only one drive motor is needed to realize the cyclic crushing of aircraft tire waste, which has lower energy consumption, simple structure, and can actively discharge aircraft tire waste with high discharge efficiency.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0020] Example 1
[0021] like Figure 1 , Figure 2 and Figure 5 As shown, a pretreatment device for recycling waste materials from aircraft tire processing includes a base plate 1; it also includes a left column 2, a left roller 3, a middle column 4, a middle roller 5, a right roller frame 6, a right roller 7, a conveyor belt 8, and a cutter roller 9. The left column 2 is installed on the left side of the base plate 1, the left roller 3 is rotatably mounted on the left column 2, the middle column 4 is installed in the middle of the base plate 1, the middle roller 5 is rotatably mounted on the middle column 4, the lower end of the right roller frame 6 is mounted on the middle column 4, the right roller 7 is rotatably mounted on the upper end of the right roller frame 6, the middle roller 5 is lower than the left roller 3 and the right roller 7, the two ends of the conveyor belt 8 are fitted onto the left roller 3 and the right roller 7, and the middle roller 5 is located in the middle of the conveyor belt 8. The middle roller 5 supports the lower middle layer of the conveyor belt 8 downwards, making the conveyor belt 8 V-shaped. The cutter roller 9 is rotatably mounted on the central column 4. Multiple cutter discs are concentrically mounted on the cutter roller 9, and the multiple cutter discs press the upper middle layer of the conveyor belt 8 onto the middle roller 5. It also includes a lower shaft seat 10, a push cylinder 11, and an ear plate 12. The lower end of the right roller frame 6 is rotatably connected to the central column 4. The lower shaft seat 10 is mounted on the base plate 1. The fixed end of the push cylinder 11 is rotatably connected to the lower shaft seat 10. The piston rod end of the push cylinder 11 is equipped with an ear plate 12, and the ear plate 12 is rotatably connected to the right roller frame 6. It also includes a surrounding plate 18, which is installed on both sides of the conveyor belt 8.
[0022] Left roller 3, middle roller 5, and right roller 7 roll to support conveyor belt 8, which is made of woven metal wire. The piston rod of push cylinder 11 extends and pushes the upper end of right roller frame 6 upward through ear plate 12, thereby causing the upper end of right roller frame 6 to drive right roller 7 higher than middle roller 5, making conveyor belt 8 V-shaped. Aircraft tire scraps are fed onto the upper surface of conveyor belt 8. By installing guard plates 18 at the edge of conveyor belt 8, the aircraft tire scraps on conveyor belt 8 are restrained, reducing the amount of aircraft tire scraps falling off. Because conveyor belt 8 is V-shaped, the aircraft tire scraps gather towards cutter roller 9. Left roller 3 is driven by a drive motor, causing left roller 3 to reciprocate. Left roller 3 drives conveyor belt 8 to reciprocate, and conveyor belt 8 drives the scraps on it to reciprocate. The scrap material from aircraft tires moves back and forth beneath multiple cutter discs of the cutter roller 9, thereby cooperating with the multiple cutter discs of the cutter roller 9 and the conveyor belt 8 to pre-treat the scrap material by cutting and crushing. After the scrap material is cut and crushed, the right roller frame 6 drives the right roller 7 to descend to be level with or slightly lower than the middle roller 5, so that the right end of the conveyor belt 8 is leveled or tilted downwards. The left roller 3 drives the conveyor belt 8 to rotate continuously, so that the conveyor belt 8 conveys the scrap material powder on it to the right end and outputs it from the conveyor belt 8. Compared with the existing technology, only one drive motor is needed to realize the cyclic crushing of the scrap material from aircraft tires, which has lower energy consumption, simpler structure, and can actively discharge the scrap material from aircraft tires, resulting in high discharge efficiency.
[0023] Example 2
[0024] like Figure 3 and Figure 4 As shown, based on Embodiment 1, it also includes a slider 13, a threaded sleeve 14, and a screw 15. The slider 13 is installed at the end of the cutter roller 9 and is slidably installed in the vertical groove of the central column 4. The threaded sleeve 14 is installed at the top of the central column 4. The lower end of the screw 15 is rotatably connected to the slider 13 and the screw 15 is rotatably screwed to the threaded sleeve 14. It also includes a crossbeam 16 and multiple paddles 17. The crossbeam 16 is installed on the central column 4, and multiple paddles 17 are installed on both the left and right sides of the crossbeam 16. The lower ends of the multiple paddles 17 extend into the cutting edges of the multiple cutter discs on the left and right sides of the cutter roller 9, respectively.
[0025] Rotating the screw 15 causes the screw 15 to engage with the threaded sleeve 14, thereby driving the slider 13 to rise and fall along the vertical groove of the central column 4, thus adjusting the height of the cutter roller 9 and the gap between the cutter roller 9 and the conveyor belt 8, achieving different crushing effects on the aircraft tire scraps. When the multiple cutter discs of the cutter roller 9 crush the aircraft tire scraps, multiple pry bars 17 push out the fragments of aircraft tire scraps clamped between the cutting edges of the cutter discs, improving the cutting efficiency of the cutter discs of the cutter roller 9.
[0026] Example 3
[0027] like Figure 1 , Figure 2 and Figure 5 As shown, based on Embodiment 1, it also includes a left scraper 19, which is mounted on the left column 2. The lower edge of the left scraper 19 is in frictional contact with the outer surface of the upper left layer of the conveyor belt 8. It also includes a rotating shaft 20, a first gear 21, a second gear 22, and a right scraper 23. The rotating shaft 20 is rotatably mounted on the right roller frame 6. The first gear 21 is concentrically mounted on the rotating shaft 20, and the second gear 22 is mounted on the ear plate 12. The second gear 22 meshes with the first gear 21. The right scraper 23 is mounted on the rotating shaft 20, and the lower end of the right scraper 23 is in frictional contact with the outer surface of the upper right layer of the conveyor belt 8.
[0028] The left scraper 19 scrapes off the residual aircraft tire material on the surface of the conveyor belt 8, allowing the scraped material to flow back to the cutter roller 9 for recycling and cutting. When the piston rod of the push cylinder 11 extends and pushes the right roller frame 6 to stand upright, the ear plate 12 drives the gear 22 to rotate relative to the right roller frame 6, thereby causing the gear 22 to mesh with the gear 21 to drive the rotating shaft 20 to rotate. This causes the rotating shaft 20 to adjust the angle of the right scraper 23, so that the lower end of the right scraper 23 comes into frictional contact with the outer surface of the upper right side of the conveyor belt 8, allowing the right scraper 23 to remove the residual aircraft tire material from the surface of the conveyor belt 8. The scraped-off aircraft tire scrap flows back to the cutter roller 9 for repeated cutting. When the piston rod of the push cylinder 11 retracts and drives the right roller frame 6 to level, the ear plate 12 drives the gear 22 to rotate in the opposite direction to the right roller frame 6. This causes the gear 22 to mesh with the gear 21, driving the rotating shaft 20 to rotate in the opposite direction. This causes the rotating shaft 20 to drive the right scraper 23 to adjust its angle in the opposite direction, so that the lower end of the right scraper 23 is no longer in contact with the outer surface of the upper right side of the conveyor belt 8. This allows the aircraft tire scrap to be discharged through the gap between the right scraper 23 and the conveyor belt 8, improving the discharge efficiency.
[0029] like Figures 1 to 5As shown, this utility model discloses a pre-treatment device for recycling aircraft tire processing waste. During operation, the piston rod of the push cylinder 11 extends and pushes the upper end of the right roller frame 6 upwards via the ear plate 12. This causes the upper end of the right roller frame 6 to drive the right roller 7 above the middle roller 5, making the conveyor belt 8 V-shaped. The aircraft tire waste is then fed onto the upper surface of the conveyor belt 8. Due to the V-shape of the conveyor belt 8, the aircraft tire waste gathers towards the cutter roller 9. Then, the left roller 3 is driven by a drive motor to reciprocate, causing the left roller 3 to drive the conveyor belt 8 to reciprocate. The conveyor belt 8 carries the aircraft tire waste back and forth under the multiple cutter discs of the cutter roller 9. The movement of the roller 9 and the conveyor belt 8 allows the multiple cutter discs of the cutter roller 9 to cooperate in the pre-treatment of cutting and crushing the aircraft tire scrap. Then, multiple pry bars 17 remove the fragments of aircraft tire scrap clamped between the cutting edges of the cutter discs. The left scraper 19 and the right scraper 23 scrape off the aircraft tire scrap on the conveyor belt 8. Finally, the aircraft tire scrap is cut and crushed. The right roller frame 6 drives the right roller 7 to descend to be level with or slightly lower than the middle roller 5, so that the right end of the conveyor belt 8 is flat or tilted downwards. The left roller 3 drives the conveyor belt 8 to rotate continuously, so that the conveyor belt 8 conveys the aircraft tire scrap powder under the right scraper 23 to the right end and outputs it.
[0030] The main functions achieved by this utility model are:
[0031] 1. Only one drive motor is needed to achieve the cyclic crushing of aircraft tire waste, resulting in lower energy consumption and a simpler structure;
[0032] 2. It can actively discharge residual materials from aircraft tires, resulting in high material discharge efficiency;
[0033] 3. The height of the cutter roller 9 can be adjusted to achieve different cutting and shredding effects.
