Description

Technical Field

[0001] The invention relates to the technical field of recycled rubber processing, in particular to a rubber particle processing device for recycled rubber. Background Art

[0002] Recycled rubber is a material obtained by recycling and reprocessing waste rubber products, such as the granulation of waste tires. The main components of old tires are rubber and steel wire. In order to recycle rubber and steel wire, it is necessary to peel the rubber from the tire and ensure that the steel wire is completely removed from the tire. On the one hand, it is helpful to reduce the steel wire content in the peeled rubber. On the other hand, it can also prevent the peeled rubber from being affected by the mixed steel wire during the subsequent crushing process.

[0003] Chinese patent publication number CN116160592A discloses a rubber stripping device for a tire. The device is provided with a rotating plate to drive a connecting plate and a cutter to contact the surface of the tire. Pressure is applied by a No. 3 support spring to make the right bottom of the cutter contact the tire surface by squeezing. When the tire rotates counterclockwise, the cutter contacts the tire and continuously removes the rubber on the tire surface. The tip of the cutter continues to penetrate the rubber layer on both sides of the tire wire and continues to remove.

[0004] Although the above patent can separate the steel wires in the tire from the tire, it can only remove the steel wires in the side of the tire that contacts the ground, while the steel wires on both sides of the tire still need to be removed manually or using a wire separator. Manual removal is inefficient and increases labor costs. Steel wire breakage may still occur when using a wire separator. Summary of the invention

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Please refer to Figure 1-9, in the embodiment of the present invention, a rubber particle processing device for recycled rubber includes a support plate 1, a fixing mechanism 2, a cutting mechanism 3, a separating mechanism 4, and a crushing mechanism 5. The support plate 1 is installed and fixed on the ground and is used to support the tire. The fixing mechanism 2 is arranged on the front surface of the support plate 1 and is rotatably connected to the support plate 1 for fixing the tire. The cutting mechanism 3 is arranged on one side of the fixing mechanism 2 and is used to strip the rubber on three sides of the tire. The cutting mechanism 3 includes a translatable U-shaped plate 31. A U-shaped guide groove 311 is formed through the top surface of the U-shaped plate 31. A sliding plate 32 is slidably connected to the top surface of the U-shaped plate 31. The bottom end of the sliding plate 32 is fixedly connected with a connecting rod 33 that penetrates and slides in the U-shaped guide groove 311. A rectangular sleeve 321 is obliquely fixed to one side surface of the sliding plate 32. A cutting tool 34 is slidably sleeved inside the rectangular sleeve 321. A plurality of first support springs 341 are fixedly connected at equal intervals between the cutting tool 34 and the rectangular sleeve 321. The separating mechanism 4 is arranged above the fixing mechanism 2 and is used to separate the steel wire in the tire from the remaining rubber of the tire. The crushing mechanism 5 is arranged below the fixing mechanism 2 and is installed and fixed on the ground and is used to crush the cut rubber and the remaining tire.

[0048] Specifically, first, move the U-shaped plate 31 away from the fixing mechanism 2, then place the tire on the fixing mechanism 2, and use the fixing mechanism 2 to fix the tire. After the tire is fixed, move the U-shaped plate 31 back to its original position again, and make the cutting tool 34 abut against one of the outer side surfaces of the tire. Then, the rotation of the fixing mechanism 2 can drive the tire to rotate. Since the cutting tool 34 is always in close contact with the outer side surface of the tire under the action of a plurality of first support springs 341, the rubber outside the steel wire in the tire can be cut off when the tire rotates under the action of the cutting tool 34. The cut-off tire rubber falls into the crushing mechanism 5 under its own gravity, and the rubber can be crushed into particles by the crushing mechanism 5. When the cutting tool 34 cuts the tire, the connecting rod 33 reciprocates in the U-shaped guide groove 311 (the three outer side surfaces of the tire are in a U-shaped structure), so that the cutting tool 34 can reciprocate along the three outer surfaces of the tire. Therefore, the rubber on the three outer side surfaces of the tire and outside the steel wire can be cut off in sequence. When the steel wire in the tire is exposed, since the end of the cutting tool 34 is serrated (such as Figure 7As shown in the figure, after the rubber outside the steel wire is shaved off, the steel wire will protrude on the remaining tire surface (similar to a thread shape). Then, the movement of the cutter 34 is stopped, and the separation mechanism 4 is used to separate the steel wire from the remaining tire. At this time, the steel wires on both sides of the tire will fall on the fixing mechanism 2, while the steel wires on the side of the tire in contact with the ground are still located outside the tire, but the steel wires have been separated from the remaining tire. Then, the staff removes the remaining tire through the fixing mechanism 2 and takes out the steel wire, and then puts the remaining tire into the crushing mechanism 5 to be crushed into particles. The device can make the cutter 34 move along the three outer sides of the tire by reciprocating movement of the connecting rod 33 in the U-shaped guide groove 311, and always closely adhere to the outer wall of the tire under the action of a plurality of first support springs 341, so that the rubber on the three outer sides of the tire can be peeled off in sequence, without the need for later treatment of both sides of the tire, thereby improving the efficiency of steel wire peeling and the efficiency of crushing and granulating waste tires.

[0049] Embodiment 1

[0050] As Figure 5-7 shown, in this embodiment, one end of the bottom surface of the U-shaped plate 31 is fixedly connected with a first vertical plate 312. Both ends of the bottom surface of the U-shaped plate 31 are rotatably connected with a first sprocket 35. Both ends of the side of the bottom surface of the U-shaped plate 31 far from the first sprocket 35 are rotatably connected with two symmetric second sprockets 36. The two first sprockets 35 and the four second sprockets 36 are connected by a chain drive. A limiting ring 331 that abuts against the bottom surface of the U-shaped plate 31 is fixedly connected to the bottom end of the outer wall of the connecting rod 33. A second connecting block 332 fixedly connected to one of the connecting pieces in the chain is fixedly connected to the bottom end of the connecting rod 33. A second motor 37 is fixedly connected to the side surface of the first vertical plate 312. The output end of the second motor 37 is fixedly connected to the corresponding first sprocket 35. An L-shaped plate 38 is fixedly connected to one side surface of the U-shaped plate 31. Two symmetric air cylinders 39 fixedly connected to the housing of the crushing mechanism 5 are fixedly connected to the bottom end of the inner side surface of the L-shaped plate 38.

[0051] In this embodiment, the drive of the second motor 37 can make the chain roll between the two first sprockets 35 and the four second sprockets 36. Since the connecting rod 33 is fixedly connected to one of the connecting pieces in the chain through the second connecting block 332, the rolling of the chain can make the cutter 34 move along the three outer sides of the tire. When the cutter 34 moves from one end of the U-shaped guide groove 311 to the other end, by reversing the rotation of the second motor 37, the cutter 34 can move in the reverse direction. By repeating this operation, the cutter 34 can reciprocate along the three outer sides of the tire. The two air cylinders 39 can make the L-shaped plate 38 drive the U-shaped plate 31 to move. When the U-shaped plate 31 moves away from the fixing mechanism 2, the tire can be fixed on the fixing mechanism 2 or the remaining tire can be taken out from the fixing mechanism 2.

[0052] Embodiment 2

[0053] like Figure 2-4 As shown, in this embodiment, the fixing mechanism 2 includes a cylindrical block 21, a plurality of electric push rods 22, a plurality of arc plates 221, and a connecting tube 24. The cylindrical block 21 is arranged directly above the crushing mechanism 5. The cylindrical block 21 is an annular structure. The outer wall of the cylindrical block 21 is provided with a plurality of embedding grooves 211 at equal angles in an annular manner. The plurality of electric push rods 22 are respectively embedded in the embedding grooves 211 fixed at corresponding positions. The plurality of arc plates 221 are respectively fixedly connected to the output ends of the electric push rods 22 at corresponding positions. The connecting tube 24 is fixedly connected to the back side of the cylindrical block 21 and rotates through the support plate 1. A pad is fixedly connected to the back side of the support plate 1. A gear ring 241 is fixedly connected to the outer wall of the connecting tube 24 located on the back side of the support plate 1. A motor 25 is fixedly connected to the top surface of the pad. A gear 251 meshing with the gear ring 241 is fixedly connected to the output end of the motor 25.

[0054] In this embodiment, the tire is placed on the cylindrical block 21, and then the multiple arc plates 221 are moved by starting the multiple electric push rods 22 until the arc plates 221 are in contact with the inner wall of the tire. At this time, the tire can be fixed, and then the connecting tube 24 can be driven by the motor 25 to drive the cylindrical block 21 to rotate, so that the tire can be rotated. The rotating tire can peel off the rubber on the outside of the steel wire under the action of the tool 34.

[0055] like Figure 2 and Figure 4 As shown, in this embodiment, the bottom surface of the embedded groove 211 is penetrated with a threading hole connected to the inside of the cylindrical block 21, the inner wall of the cylindrical block 21 and one end close to the support plate 1 is fixedly connected with a threading tube 23 that penetrates the connecting tube 24, the outer wall of the threading tube 23 located outside the connecting tube 24 is fixedly connected with a conductive slip ring 26, both ends of the cylindrical block 21 are fixedly connected with a retaining ring 212, the outer wall of the conductive slip ring 26 is fixedly connected with a connecting block 261 that is fixedly connected to the back of the support plate 1, the bottom end of the front side of the support plate 1 is fixedly connected with a connecting plate 11 that is fixedly connected to the outer shell of the crushing mechanism 5, and the top surface of the connecting plate 11 is fixedly connected with a column 12 that penetrates and rotates with the connecting tube 24.

[0056] In this embodiment, the wires of the electric push rod 22 are passed through the threading holes at the corresponding positions and out of the threading tube 23, and then the wires of multiple electric push rods 22 are connected to the conductive slip ring 26 (the conductive slip ring 26 is a prior art, so it is not described in detail), and then the conductive slip ring 26 is connected to an external power source through the wire, so that the multiple electric push rods 22 can be energized, thereby preventing the wires of the multiple electric push rods 22 from being entangled and broken. The connection plate 11 is fixed to the outer shell of the crushing mechanism 5 to increase the stability of the support plate 1, and the connection tube 24 is supported by the column 12 to increase the stability of the cylindrical block 21. The stability of the threading tube 23 can be increased by the connecting block 261 and the conductive slip ring 26.

[0057] Embodiment 3

[0058] like Figure 8 and Fig. 9 As shown, in this embodiment, the separation mechanism 4 includes a movable plate 41, a bidirectional screw 42, two symmetrical movable blocks 43, a vertical plate 44, and two symmetrical cutters 45. The movable plate 41 is arranged on the front side of the support plate 1 and is located above the cylindrical block 21 for movement. A slide groove 411 is provided on the bottom surface of the movable plate 41. The bidirectional screw 42 is rotatably connected between the two short side surfaces of the slide groove 411. Two symmetrical movable blocks 43 respectively penetrate and screw on the two ends of the outer wall of the bidirectional screw 42. The bottom end of the movable block 43 is detachably connected with a cutter 431. The vertical plate 44 is fixedly connected to the bottom surface of the movable plate 41 and close to one end of the support plate 1. Two symmetrical limiting holes 441 are provided on the side surface of the vertical plate 44. The two symmetrical cutters 45 are slidably connected to the inside of the limiting holes 441 at the corresponding positions. The ends of the two cutters 45 are fixedly connected There is a connecting plate, and two symmetrical supporting springs 451 are fixedly connected between the connecting plate and the vertical plate 44. An electric push rod 412 is embedded and fixed on the top surface of the support plate 1, and the output end of the electric push rod 412 is fixedly connected to the moving plate 41. A butt plate 46 is arranged between the connecting plate and the support plate 1, and two symmetrical electric push rods 461 are embedded and fixedly connected on the back of the support plate 1, and the output end of the electric push rod 461 is fixedly connected to the butt plate 46. The moving plate 41 and the side ends close to the support plate 1 are fixedly connected with fixed blocks 413, and a reel is rotatably connected between the two fixed blocks 413. A pull rope 414 fixedly connected to the connecting plate is wound and fixed on the outer wall of the reel, and a circular ring 415 is fixedly connected on the opposite side of the two fixed blocks 413 and located on the outside of the reel, and a clockwork spring is arranged between the circular ring 415 at the corresponding position at both ends of the reel and the outer wall.

[0059] In this embodiment, first, magnets are embedded in the side of the abutment plate 46 opposite to the connecting plate. When the rubber on the outer side of the tire steel wire is cut off by the cutter 34, the steel wire will protrude on the outer side of the remaining tire under the action of the serrated cutter 34. At this time, the staff can adjust the spacing between the two cutters 1 431 by rotating the bidirectional screw 42, so that the two cutters 1 431 can be inserted between the steel wire on both sides of the tire and the remaining tire respectively. Then, the moving plate 41 can drive the two cutters 1 431 and the two cutters 2 45 to move downward by driving the electric push rod 2 412. When the moving plate 41 After moving down to a certain distance, the ends of the two cutters 45 contact the outer wall edge in the middle of the tire, and the continued downward movement of the moving plate 41 can make the two cutters 45 move up along the limiting holes 441 at the corresponding positions. Since the ends of the two cutters 45 contact the edge of the tire, the downward movement of the moving plate 41 will make the ends of the two cutters 45 move up, and the other ends of the two cutters 45 can be kept in a horizontal state under the action of the two pull ropes 414 and the two springs (although the two support springs 451 are pulled up and down at this time, it does not affect the two cutters 45). 5 is kept horizontal under the action of two spring springs and two pull ropes 414. When the two cutters 1 431 are completely inserted between the steel wire and the remaining tire at the corresponding positions, the two electric push rods 3 461 are activated to enable the plate 46 to drive the two cutters 2 45 to move until the two cutters 2 45 are inserted between the steel wire and the tire at the middle position of the tire. The tire is driven to rotate by the fixing mechanism 2, so that the two cutters 1 431 and the two cutters 2 45 can separate the steel wire located on the three outer sides of the tire from the remaining tire. At this time, the steel wires on both sides of the tire fall on the cylindrical block 2. 1, and the middle steel wire is hung on the two cutters 2 45, so as to ensure that the separated steel wire maintains integrity for direct use later. After the steel wire is separated, the two cutters 2 45 are pulled out from between the steel wire in the middle and the remaining tires by the two electric push rods 3 461, and then the two cutters 1 431 are pulled up by the electric push rod 2 412, so that the cutters 1 431 are pulled out from between the steel wire and the remaining tires at the corresponding positions. Then the staff can remove all the steel wires and the remaining tires from the cylindrical block 21, and put the remaining tires into the crushing mechanism 5.
