Description

Technical Field

[0001] This invention relates to the field of tire recycling technology, specifically to a waste tire shredding and recycling device. Background Technology

[0002] Currently, waste tire shredding and recycling equipment typically employs a multi-stage crushing and screening process. Existing equipment generally includes a crushing mechanism, a screening mechanism, and a material conveying mechanism. The crushing mechanism often uses a double-roller or crushing drum structure to break the tires into rubber blocks or granules through shearing and compression. The screening mechanism usually uses a vibrating screen or rotary screen to classify the crushed material by particle size. In actual production, crushing and screening are often controlled by two independent drive systems—the crushing rollers are driven by a main motor, while the screening mechanism requires a separate vibrating motor or eccentric wheel mechanism to drive its reciprocating motion.

[0003] However, this traditional split-drive structure has the following technical problems: First, the screening mechanism needs to be equipped with an independent power source, which increases the manufacturing cost and energy consumption of the equipment; Second, most screening mechanisms use vibration to screen, which causes the material to jump on the screen, making it easy to fall off and difficult to discharge the material on the screening mechanism. Summary of the Invention

[0004] This invention aims to solve the technical problems existing in the prior art, and innovatively proposes a waste tire crushing and recycling device that can swing and screen as soon as the crushing roller is started, with high screening efficiency and automatic material discharge.

[0005] To achieve the above objectives, the present invention provides a waste tire shredding and recycling device, including a shredding box, which is fixed above the ground by supporting columns on the front and rear sides. The top of the shredding box is open, and the bottom of the shredding box has a discharge port. A screening mechanism is located below the discharge port. A pair of shredding rollers are horizontally arranged inside the shredding box, and each of the two shredding rollers is equipped with a separate rotating motor. The screening mechanism includes a screen with a lower front and a higher rear, and a swing structure is provided on the rear side of the screen. The front end of the screen has a swing base for swinging, and the screen is fixed above the ground by the swing base. The rotating shafts of the two shredding rollers pass through the shredding box and are coaxially connected to a turntable. The swing structure includes a sliding plate located directly behind the two turntables. A pair of slide rails are vertically arranged on the rear side wall of the shredding box corresponding to the two sliding plates. The left and right sides of the sliding plates are engaged in the corresponding slide rails. Both sliding plates have horizontally arranged strip holes. The turntables have cylindrical protrusions that are eccentrically arranged and engaged in the strip holes. The bottom of the two sliding plates is connected to the left and right sides of the screen by hanging ropes.

[0006] In the above scheme: the swing base is a universal ball hinge.

[0007] In the above scheme: the universal ball hinge is located in the middle of the bottom side of the front end of the screen.

[0008] In the above scheme: there are two supporting columns on the front side, the front side of the screen is located between the two supporting columns, and a crossbeam is provided between the two supporting columns below the screen. The base of the universal ball hinge is installed on the crossbeam.

[0009] In the above scheme, the protrusions are all located on the left or right side of the corresponding turntable, so that when any one protrusion is at the highest point, the other protrusion is located in the lower half of the corresponding turntable, thereby enabling the screen to tilt left and right and swing left and right.

[0010] In the above scheme: there is a gap between the crushing roller and the bottom of the crushing box, the bottom of the crushing box is inclined with the front higher than the back, and the discharge port is located on the rear side of the crushing box.

[0011] In the above scheme: a vertical rod is vertically arranged in the middle of the bottom side of the skateboard, a ring is arranged on the bottom side of the vertical rod, and one end of the hanging rope is fixed to the ring.

[0012] In the above scheme: there are three supporting columns on the rear side, and all of them are fixed on the rear side wall of the crushing box. The three supporting columns are respectively set on both sides and between the two slide plates, and the supporting columns on the rear side are vertically provided with sliding grooves for the corresponding slide plates to be inserted into, forming a slide rail through the sliding grooves.

[0013] In the above scheme, the left and right sides and the rear side of the screen frame are all provided with edging to prevent the material on the screen from falling directly from the left and right sides.

[0014] In summary, the beneficial effects of this invention are as follows: The oscillating structure enables the screen to reciprocate with the rotation of the crushing roller, thereby completing the screening operation without adding an additional power source. This achieves coordinated crushing and screening, high synchronization, and a simple structure, minimizing equipment investment costs. The sliding plate and turntable form a linkage mechanism, enabling the screen to oscillate left and right, thus screening the material. The screen's front-lower-rear-high setting allows the material to slide or roll forward under gravity, being screened during its forward movement and falling off the front side, thus discharging the material from the screen and preventing excessive material from affecting screening efficiency. The hanging rope prevents the screen from jamming, demonstrating a reasonable design and high flexibility. Attached Figure Description

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0021] like Figures 1-5 As shown, a waste tire shredding and recycling device includes a shredding box 1. The top of the shredding box 1 is open, and the bottom of the shredding box 1 is narrowed and has a discharge port 16. A screening mechanism is arranged below the discharge port 16. A pair of shredding rollers 3 are horizontally arranged inside the shredding box 1, and each of the two shredding rollers 3 is equipped with a rotating motor 2. The rotating motor 2 on the left rotates in the opposite direction, thus causing the two shredding rollers 3 to rotate in opposite directions. Support columns 4 are provided at both the front and rear ends of the shredding box 1. There are two support columns 4 on the front side, and a placement plate for placing the rotating motor 2 is provided on the upper part between the front support columns 4. There is a gap between the shredding rollers 3 and the bottom of the shredding box 1, and the bottom of the shredding box 1 is inclined with the front higher than the back, and the discharge port 16 is located on the rear side of the shredding box 1.

[0022] The screening mechanism includes a screen 14 with a lower front and higher rear, and the screen 14 is equipped with an outer frame. A crossbeam 10 is located below the screen 14 between two supporting columns 4. A swing structure is provided on the rear side of the screen 14. The middle of the bottom front side of the outer frame of the screen 14 is connected to the crossbeam 10 via a universal ball hinge 11, allowing the screen 14 to swing left and right. Specifically, the base of the universal ball hinge 11 can be installed on the crossbeam 10, and the ball head of the universal ball hinge 11 can be installed in the middle of the bottom front front side of the outer frame of the screen 14. The thickness of the outer frame of the screen 14 is greater than the front side, and the top height of the left, right, and rear sides is all above the screen surface, forming a perimeter to prevent material from falling off the screen 14 from the left and right sides. The front side of the screen 14 is located between the two supporting columns 4, allowing material to fall directly from the screen 14 onto the front side of the crushing box 1, a reasonable design.

[0023] The shaft of the crushing roller 3 passes through the crushing box 1 and is coaxially connected to the turntable 7. A sliding plate 5 is provided directly behind the two turntables 7. The sliding plate 5 is larger than the turntable 7. A strip hole 12 is provided horizontally in the center of each of the two sliding plates 5. A cylindrical protrusion 6 is provided eccentrically on the turntable 7 and is inserted into the strip hole 12.

[0024] There are three rear support columns 4, all installed on the rear wall of the crushing box 1. The three support columns 4 are evenly spaced and located on the left and right sides and between the two turntables 7, respectively. Vertical grooves are opened on the rear support columns 4 for the left and right sides of the slide plate 5 to engage, thus forming a slide rail 8 for the slide plate 5 to slide up and down. The top of the grooves are connected and the bottom extends to the bottom of the turntable 7 to meet the sliding requirements of the slide plate 5. A vertical rod is set in the middle of the bottom side of the slide plate 5, and a ring 13 is set on the bottom side of the vertical rod. A hanging rope 15 is connected between the ring 13 and the outer frame.

[0025] The protrusions 6 are all located on the left or right side of the corresponding turntable 7, so that when any one protrusion 6 is at the highest point, the other protrusion 6 is located in the lower half of the corresponding turntable 7, thereby allowing the screen 14 to tilt left and right and swing left and right.

[0026] In operation, waste tires are first placed into the crushing box 1, where the crushing roller 3 crushes them. The resulting tire fragments fall from the discharge port 16 at the bottom rear of the crushing box 1 onto the screen 14. Simultaneously, the rotation of the crushing roller 3 drives the turntable 7 to rotate, causing the eccentrically positioned protrusions 6 on the turntable 7 to move in a circular motion, which in turn causes the sliding plate 5 to slide up and down. Since the two turntables 7 rotate in opposite directions, the sliding plates 5 also move in opposite directions, i.e., the hanging rope 15 drives the screen 14 to move up and down on both sides, achieving a swinging motion to sieve the tire fragments. Furthermore, the screen 14 is positioned with a lower front and a higher back; if a tire fragment remains in the mesh after moving to the front of the screen 14, it will slide out from the front of the screen 14, achieving discharge.
