Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of regenerated rubber production, and particularly relates to an environment-friendly regenerated rubber production process. BACKGROUND

[0002] With the rapid development of industrialization, a large amount of waste tires and other waste rubbers will be produced every year. Since the rubber has good chemical stability, the waste rubber products cannot be naturally decomposed, and combustion will produce toxic gases, and storage will occupy a large space. The recycling of waste tires and other waste rubbers has important significance for environmental protection and rational utilization of resources. At present, there are many methods for recycling waste tires. Generally, the waste vulcanized rubber is mechanically and chemically treated under heating and pressurization to degrade the network crosslinked structure of the rubber and become plastic, thereby becoming regenerated rubber.

[0003] At present, in the production process of environment-friendly regenerated rubber, the tire is generally cleaned first, then crushed after cleaning, and the crushed particles are air-separated and magnetically separated, and then devulcanized and refined to produce regenerated rubber. However, in the cleaning process, the tire is manually washed, the degree of automation is low, the cleaning effect is poor, and the rubber in the tire mouth contains coarse steel wires, which is not easy to crush and also causes waste of steel wires.

[0025] 1. By installing four telescopic columns and a support mechanism, the tire can be mounted on the loading column. When the conductive head contacts the arc-shaped conductive rail, the four electromagnets inside the loading column are energized.

[0040] Reference Figures 1-8 An environmentally friendly recycled rubber production process utilizes an environmentally friendly recycled rubber production device. This device includes a base 1, four rotatable telescopic columns and a support mechanism, a washing mechanism, a drying and heating mechanism, and an extrusion and cutting mechanism. The specific processing steps for producing environmentally friendly recycled rubber using this device are as follows:

[0041] S1. Load the tire onto one of the telescopic columns and lift the tire from the middle through the corresponding support mechanism;

[0042] S2. Rotate the telescopic column to the position of the corresponding brushing mechanism. The telescopic column extends and pushes the tire into the brushing mechanism for brushing, removing the mud, sand and oil stains remaining on the tire sidewall.

[0043] S3. After washing, the tire is moved to the corresponding drying and heating mechanism. The tire is then pushed into the drying and heating mechanism again through the telescopic column for drying. At the same time, the tire is heated and softened, making it easier to squeeze later.

[0044] S4. After drying and heating, the tire is rotated to the corresponding extrusion and cutting mechanism position and pushed into the extrusion and cutting mechanism through the telescopic column. The heated tire is extruded into a flat shape. Then, the rubber edges at the tire bead on both sides are cut off to separate the tire bead rubber and the middle rubber. Coarse steel wires can be separated from the tire bead rubber, and capillary steel wires can be separated from the middle rubber.

[0045] An electric rotating column 2 is installed on the base 1, and four telescopic columns are fixedly installed on the electric rotating column 2;

[0046] The support mechanism includes a loading column 10 installed at the telescopic end of the telescopic column. The circumferential sidewall of the loading column 10 is provided with multiple sliding grooves 34, and a support plate 11 that can move radially at the same time is slidably installed in each of the multiple sliding grooves 34.

[0047] The scrubbing mechanism includes a rotating cylinder 12, with a ring of brushes 27 and an annular water pipe 26 installed on the inner wall of the rotating cylinder 12. The annular water pipe 26 has multiple spray nozzles circumferentially arranged on the inner wall.

[0048] The extrusion cutting mechanism includes an extrusion table 22 mounted on a base 1. The extrusion table 22 is provided with an extrusion groove 32 for placing a tire. An extrusion plate 37 that can move up and down is mounted above the extrusion table 22. Cutting components are mounted on both sides of the extrusion plate 37. Belt conveyors 21 are mounted on both the front and rear sides of the extrusion table 22.

[0049] Furthermore, the telescopic column includes a fixed arm 4 and a connecting rod 6. The fixed arm 4 has a cavity 7 inside. The connecting rod 6 is elastically connected to the cavity 7 by a first spring 5. The end of the connecting rod 6 extends out of the cavity 7 and is fixedly connected to the loading column 10. A push plate 8 is fixed on the extension section of the connecting rod 6. A drive assembly that can drive the telescopic column to extend is installed on the base 1.

[0050] Specifically, the drive assembly includes three cylinders 30 mounted on the base 1. The positions of the three cylinders 30 correspond to the washing mechanism, the drying and heating mechanism, and the extrusion and cutting mechanism, respectively. The telescopic ends of the three cylinders 30 are all fixedly connected to the abutment plate 31 that cooperates with the push plate 8. When the cylinder 30 at the corresponding position is activated, the abutment plate 31 pushes the push plate 8, pulls out the connecting rod 6, and then pushes out the tire for washing, drying, and extrusion cutting.

[0051] Furthermore, a baffle 9 is fixedly installed at the connection between the loading column 10 and the connecting rod 6.

[0052] Furthermore, the connecting rod 6 extends into the loading column 10, and four electromagnets 36 are installed on the circumferential sidewall of the extension section. A magnetic block 35 that cooperates with the corresponding electromagnet 36 is embedded in the bottom of the support plate 11. A second spring is elastically installed between the two sides of the support plate 11 and the inner wall of the slide groove 34. An arc-shaped conductive rail 3 with an external power supply is installed on the base 1. A conductive head 33 that cooperates with the arc-shaped conductive rail 3 is installed at the bottom of the fixed arm 4. The conductive head 33 is electrically connected to the corresponding electromagnet 36. When the conductive head 33 at the bottom of the corresponding telescopic column contacts the arc-shaped conductive rail 3, the four electromagnets 36 in the loading column 10 are energized. The magnetic repulsion between the magnetic block 35 and the electromagnet 36 is greater than the elastic force of the second spring, thereby simultaneously driving the four support plates 11 to slide radially out of the slide groove 34. The support plate 11 extends into the tire, thereby supporting the tire.

[0053] Furthermore, a mounting plate 17 is fixedly installed on the base 1, and a hollow rotating shaft 15 is rotatably connected to the mounting plate 17. One end of the hollow rotating shaft 15 is fixedly connected to the rotating cylinder 12, and the hollow rotating shaft 15 is connected to the annular water pipe 26. A water pump 14 is installed on the mounting plate 17, and a water outlet pipe is connected to the water outlet end of the water pump 14. The end of the water outlet pipe is connected to the other end of the hollow rotating shaft 15 through a rotary joint. When the water pump 14 is started, water enters the hollow rotating shaft 15 through the water outlet pipe, then enters the annular water pipe 26, and is finally sprayed out through multiple water nozzles, thereby realizing a comprehensive brushing process of the tire outer wall.

[0054] Furthermore, a motor 16 is mounted on the mounting plate 17. The output shaft of the motor 16 is fixedly connected to a gear 18. A gear ring 13 that meshes with the gear 18 is fixed to the side wall of the rotating cylinder 12. When the motor 16 is started, the rotating cylinder 12 is driven to rotate through the gear 18 and the gear ring 13, which in turn drives the inner ring of brushes 27 to rotate.

[0055] Specifically, the drying and heating mechanism includes a mounting base 19 installed on the base 1. The side wall of the mounting base 19 is provided with a drying trough 28 adapted to the tire. The inner wall of the drying trough 28 is equipped with an annular air duct 29. The side wall of the annular air duct 29 is provided with multiple air outlets. A hot air blower 20 connected to the annular air duct 29 is installed on the top of the mounting base 19. When the hot air blower 20 is started, hot air is blown out through the multiple air outlets on the annular air duct 29 to quickly dry the moisture on the tire and heat the tire at the same time, making it softer and easier for subsequent extrusion processes.

[0056] Furthermore, the front side of the extrusion table 22 is provided with an inclined guide port 23, and a top plate 24 is fixedly installed on the top of the extrusion table 22. A first hydraulic cylinder 25 is installed on the top plate 24. The telescopic end of the first hydraulic cylinder 25 is fixedly connected to the extrusion plate 37. Under the action of the baffle 9, the tire is lifted upward through the guide port 23 and continues to push the tire into the extrusion groove 32. The first hydraulic cylinder 25 is activated to drive the extrusion plate 37 to move downward, extruding the round tire into a flat shape.

[0057] Specifically, the cutting assembly includes grooves 39 on both sides of the extrusion plate 37, a cutting blade 38 is provided in the grooves 39, multiple abutment rods 40 are fixedly installed on the top of the cutting blade 38, the upper ends of the multiple abutment rods 40 extend out of the grooves 39 and are fixedly connected to the connecting plate 42, a third spring 41 is sleeved on the multiple abutment rods 40, a fixing plate 43 is fixedly installed on the top of the extrusion plate 37, and a second hydraulic cylinder 44 is installed on both sides of the fixing plate 43, the telescopic end of the second hydraulic cylinder 44 is fixedly connected to the corresponding connecting plate 42.

[0058] The tire is mounted on the loading column 10 on the front side. The electric rotating column 2 is started to drive the telescopic column to rotate. When the conductive head 33 at the bottom of the telescopic column contacts the arc-shaped conductive rail 3, the four electromagnets 36 inside the loading column 10 are energized. The magnetic repulsion between the magnetic block 35 and the electromagnet 36 is greater than the elastic force of the second spring, which in turn drives the four support plates 11 to slide radially out of the groove 34. The support plates 11 extend into the tire and support the tire. Driven by the electric rotating column 2, the tire can automatically rotate to the corresponding brushing mechanism, drying and heating mechanism and extrusion and cutting mechanism. After rotating to the corresponding position, the cylinder 30 at the corresponding position can be activated. The abutment plate 31 pushes the push plate 8 and pulls out the connecting rod 6, thereby pushing the tire out for brushing, drying and extrusion cutting. The degree of automation is high.

[0059] First, rotate to the position of the rotating cylinder 12. After the support mechanism pushes the tire into the rotating cylinder 12, start the motor 16. The rotating cylinder 12 is driven to rotate through the gear 18 and the gear ring 13, which in turn drives the inner ring of brushes 27 to rotate. At the same time, start the water pump 14. Water enters the hollow rotating shaft 15 through the water outlet pipe, then enters the annular water pipe 26, and finally sprays out through multiple water nozzles, thereby achieving a comprehensive brushing process on the outer wall of the tire, effectively washing away mud, sand and oil stains.

[0060] After washing, the tires are transferred to the drying and heating mechanism. The tires are pushed into the drying trough 28, and the hot air blower 20 is activated. Hot air is blown out through multiple air outlets on the annular air duct 29, quickly drying the moisture on the tires and simultaneously heating them to soften them for easier subsequent extrusion. The heated tires are then transferred to the extrusion and cutting mechanism. At this point, the conductive head 33 disengages from the arc-shaped conductive rail 3, and the support plate 11 resets under the action of the second spring, allowing the tire to be hung on the loading column 10. During the tire's ejection process, it passes through the guide port 23 under the action of the baffle 9. The tire is lifted upwards and pushed into the extrusion groove 32. The first hydraulic cylinder 25 is activated to move the extrusion plate 37 downwards, extruding the round tire into a flat shape. Then, the two second hydraulic cylinders 44 are activated, which drive the two cutting blades 38 downwards through the connecting plate 42 and the push rod 40 to cut the sides of the tire, thereby cutting off a ring of rubber at the tire bead. The middle rubber and the tire bead rubber are manually fed into the corresponding belt conveyor 21 and sent to the next process. The middle rubber is directly crushed, and the tire bead rubber is recycled for coarse steel wire.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
