Description

Technical Field

[0001] This invention relates to the field of shredder equipment, and more specifically to a tire dual-shaft shredder. Background Technology

[0002] Material recycling is the collection process of processing and reusing waste materials generated during human activities. When waste materials are large in size, they are not easy to recycle. They usually need to be shredded or crushed into smaller pieces to facilitate recycling. Shredders are commonly used in the material recycling process. Large waste materials are fed into the shredder, which then shreds them to obtain materials of the appropriate size. However, during the shredding process, the blades wear down and become smaller. Once worn down, the blades are no longer sufficient and need to be replaced, resulting in low blade utilization. Furthermore, in tire shredding, due to the large diameter of tires, if they are fed laterally, they are difficult to bite and shred, leading to low shredding efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention aims to provide a tire biaxial shredder, in which the worn blades do not need to be discarded, but can be installed in a suitable position for continued use.

[0004] This invention is achieved using the following technical solution:

[0005] A dual-shaft tire shredder includes a housing, a shredding roller shaft, and a tire positioning mechanism for positioning the tire before shredding. The shredding roller shaft and the tire positioning mechanism are mounted on the housing, with the tire positioning mechanism located above the shredding roller shaft. The shredding roller shaft includes a rotating shaft and several blades. The blades are mounted on the rotating shaft and are detachably connected to it. The size of the blades gradually decreases from the center of the rotating shaft to both sides. The tire positioning mechanism includes several rollers distributed on both sides, with the gap between the two rollers forming a tire channel for the tire to pass through.

[0006] Preferably, the device includes several fixed blades, which are mounted on the machine housing and are detachably mounted to the machine housing. The size of the fixed blades gradually decreases from the fixed blade located in the middle to the fixed blades located on both sides.

[0007] Preferably, the shredding roller shaft is provided with a plurality of annular cutter holders, and the blades are disposed on the annular cutter holders. The annular cutter holders are distributed at intervals on the rotating shaft, and the intervals between the annular cutter holders gradually decrease from the middle to the sides, with the fixed blades extending into the corresponding intervals.

[0008] Preferably, there are two shredding rollers, namely a first shredding roller and a second shredding roller. The blades of the first shredding roller extend into the gap of the annular cutter holder of the second shredding roller, and the blades of the second shredding roller extend into the gap of the annular cutter holder of the first shredding roller.

[0009] Preferably, the shredding position where the first shredding roller shaft and the second shredding roller shaft intersect is located below the position between the two rollers.

[0010] Preferably, the housing is provided with a discharge port, the shredding roller shaft is located inside the housing, and the discharge port is located directly below the first shredding roller shaft and the second shredding roller shaft.

[0011] Preferably, the tire positioning mechanism includes a drive mechanism connected to the roller, the drive mechanism being used to drive the roller to rotate.

[0012] Preferably, the roller is provided with several racks, which are arranged in an array around the central axis of the roller.

[0013] Preferably, the side of the rack away from the roller is arranged in an arc shape.

[0014] Preferably, the housing is provided with a feed inlet, and the housing is provided with a feeding space. The feed inlet is connected to the feeding space, and the feed inlet is located directly above the feeding space. The rollers are located in the feeding space and are arranged on both sides inside the feeding space.

[0015] Compared to existing technologies, the advantages of this invention are as follows: The dual-shaft tire shredder of this invention uses blades of different sizes. The blades located in the middle of the shaft are larger, and the blade size gradually decreases from the middle of the shaft to both sides. Since the blades in the middle of the shaft are primarily responsible for shredding materials, they wear out faster. After wear, the blades become smaller and can be removed and installed in a shaft position suitable for their size, allowing them to continue to be used and improving their durability. Furthermore, the dual-shaft tire shredder of this invention incorporates a tire positioning mechanism. The gap between the two rollers forms a tire channel, the width of which is pre-set to be smaller than the tire's diameter but larger than its thickness. As the tire enters the channel, it is positioned vertically or nearly vertically by the rollers on both sides. Finally, under the influence of gravity, the tire falls to the shredding position for shredding, preventing the tire from being inserted laterally into the shredding position and affecting the shredding process, thus improving shredding efficiency. In addition, because the rollers rotate, using them to position the tires makes it easier for them to fall. Attached Figure Description

[0023] The following is combined with Figure 1-6 The technical solution provided by the invention will be described in more detail.

[0024] like Figure 1-6 As shown, an embodiment of the present invention provides a tire dual-shaft shredder, including a housing 1, a shredding roller 2, and a tire positioning mechanism 3 for positioning the tire before shredding. The shredding roller 2 and the tire positioning mechanism 3 are disposed on the housing 1, with the tire positioning mechanism 3 located above the shredding roller 2.

[0025] The shredding roller 2 includes a rotating shaft 4 and several blades. The blades are mounted on the rotating shaft 4 and are detachable from it. The size of the blades gradually decreases from the center of the rotating shaft 4 to the sides. By setting the blades to different sizes, the blades located in the center of the rotating shaft 4 are larger, and the size of the blades gradually decreases from the center of the rotating shaft 4 to the sides. Since the blades in the center of the rotating shaft 4 are mainly responsible for shredding materials during the process, they wear out faster. After the blades wear down, they become smaller. The smaller blades can be removed and installed in a position on the rotating shaft 4 that is the appropriate size for the blade, allowing the worn blades to continue to be used and improving their durability.

[0026] The tire alignment mechanism 3 includes two rollers 5, distributed on both sides, with the gap between them forming a tire channel 6 for the tire to pass through. The tire alignment mechanism 3 also includes an adjustment mechanism 7, on which the rollers 5 are mounted. The adjustment mechanism 7 is used to adjust the position of the rollers 5. By providing the adjustment mechanism 7, the distance between the two rollers 5 can be preset according to the size of the tire to be shredded, ensuring that the width of the tire channel 6 is less than the tire's diameter but greater than its thickness. This prevents the tire from being inserted laterally into the shredding position, affecting the bite and shredding process, and improves shredding efficiency. The two rollers 5 are located at the same height, making the tire channel 6 more stable in correcting the tire's position.

[0027] The tire dual-shaft shredder includes several fixed blades mounted on the housing 1. The fixed blades are detachable from the housing 1, and their size gradually decreases from the central blade to the blades on either side. The fixed blades, driven by the rotating shaft 4, enhance the shredding effect of the material. By setting the fixed blades to different sizes, with the central blade being larger and gradually decreasing in size towards the blades on either side, the material is primarily shredded in the center. Therefore, the central blade wears out faster than the blades on either side. As the blades wear down, they become smaller and can be removed and reinstalled in positions suitable for their new size, allowing them to continue to be used and improving their durability.

[0028] The shredding roller 2 is equipped with several annular cutter holders 8, with blades mounted on them. The annular cutter holders 8 are spaced apart on the rotating shaft 4, with the spacing gradually decreasing from the center to the sides. Fixed blades extend into the corresponding intervals. This structure, with the coordinated arrangement of the blades and fixed blades, improves the shredding effect of the equipment on materials.

[0029] Two shredding rollers 2 are provided: a first shredding roller 9 and a second shredding roller 10. The blades of the first shredding roller 9 extend into the gaps of the annular cutter holders 8 of the second shredding roller 10, and the blades of the second shredding roller 10 extend into the gaps of the annular cutter holders 8 of the first shredding roller 9. With the above structure, the cooperation between the first shredding roller 9 and the second shredding roller 10 improves the shredding effect of the equipment on materials.

[0030] The shredding position where the first shredding roller shaft 9 and the second shredding roller shaft 10 intersect is located below the position between the two rollers 5. This means the tire passage 6 is located directly above the intersection of the first shredding roller shaft 9 and the second shredding roller shaft 10. When the tire passes through the tire passage 6, it falls to the shredding position where the first shredding roller shaft 9 and the second shredding roller shaft 10 intersect, improving the tire shredding efficiency. The first shredding roller shaft 9 and the second shredding roller shaft 10 are located at the same height. By setting the first shredding roller shaft 9 and the second shredding roller shaft 10 to the same height, it is more conducive to shredding the material and to the discharge of the shredded material.

[0031] The casing 1 is provided with a discharge port 11, and the shredding roller 2 is located inside the casing 1. The discharge port 11 is located directly below the first shredding roller 9 and the second shredding roller 10. Since most of the shredded material falls between the first shredding roller 9 and the second shredding roller 10, after the tire is shredded by the first shredding roller 9 and the second shredding roller 10, the tire can fall from between the first shredding roller 9 and the second shredding roller 10 to the discharge port 11, which is more conducive to the discharge of the shredded material from the discharge port 11, speeds up the discharge time, and prevents blockage.

[0032] Several blade holders 12 are arranged on the inner wall of the casing 1. Fixed blade mounting positions 13 are provided above and below each blade holder 12. The fixed blades are mounted on the fixed blade mounting positions 13 at an angle, with their blade edges facing the shredding roller shaft 2. This improves the shredding effect of the fixed blades on the material. The blade holders 12 are distributed on the sides of the first shredding roller shaft 9 and the second shredding roller shaft 10, further enhancing the shredding effect of the fixed blades on the material.

[0033] Each annular cutter holder 8 is provided with several blade mounting positions 14. The blades are mounted on the blade mounting positions 14 and are arranged in an array around the central axis of the annular cutter holder 8, which makes the distribution of the blades more uniform and the shredding effect of the equipment on materials better.

[0034] The tire positioning mechanism 3 includes a drive mechanism 15, which is connected to the roller 5 and drives the roller 5 to rotate. The drive mechanism 15 includes two motors, which are connected to the two rollers 5 respectively, enabling the rollers 5 to rotate. During the process of inserting a tire into the tire channel 6, the rotation of the rollers 5 can further push the tire to the shredding position, preventing blockage.

[0035] The roller 5 is equipped with several racks 16, which are arranged in an array around the central axis of the roller 5. The racks 16 enhance the grip of the roller 5 on the tire, thus preventing tire slippage. The side of the racks 16 furthest from the roller 5 is arc-shaped. Since this side of the racks 16 will contact the tire, the arc shape prevents the racks 16 from piercing the tire and causing it to become stuck on the roller 5.

[0036] Baffles 17 are provided on both sides above the feeding space 19, and each baffle 17 corresponds to a roller 5. The top of the baffle 17 is provided with a downwardly inclined guide surface 18. By providing the baffles 17, the guide surface 18 on the baffle 17 plays the role of guiding the tire, and the guide surface 18 guides the tire to the tire channel 6.

[0037] The casing 1 is provided with a feed inlet 20, and the inside of the casing 1 is provided with a feeding space 19. The feed inlet 20 is connected to the feeding space 19 and is located directly above the feeding space 19. The rollers 5 are located in the feeding space 19 and are arranged on both sides inside the feeding space 19. After a tire is put into the machine through the feed inlet 20, the tire will enter the tire channel 6 under the action of gravity. The tire channel 6 corrects the state of the tire to prevent the tire from being put into the shredding position in a lateral state.

[0038] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
