[0002] Plastic runways are essential facilities in modern track and field venues. Compared with traditional soil runways, they have good anti-slip, wear-resistant, and shock-absorbing properties. The plastic particles in plastic runways mostly come from waste rubber products.

[0003] Currently, when producing plastic particles for plastic runways through a granulator, high heat is generated when the crushing blades rub against waste rubber products, which easily causes the rubber to melt and adhere to the surface of the crushing blades, reducing the crushing efficiency and the service life of the crushing blades. For this reason, we propose a plastic granulator with a screening function. Content of the Utility Model

[0004] The purpose of the utility model is to provide a plastic granulator with a screening function, which has the advantages of being able to cool the crushing blades by air cooling when the crushing blades crush waste rubber products and produce plastic particles for plastic runways, avoiding the rubber from melting and adhering to the outer surface of the crushing blades, improving the crushing and granulation efficiency and extending the service life of the crushing blades at the same time, and solving the problem that when producing plastic particles for plastic runways through a granulator, high heat is generated when the crushing blades rub against waste rubber products, which easily causes the rubber to melt and adhere to the surface of the crushing blades, reducing the crushing efficiency and the service life of the crushing blades.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A plastic granulator with a screening function includes a screening box and a crushing pipe. One side of the upper surface of the screening box is fixedly connected with the crushing pipe.

Detailed implementation manners

[0021] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Embodiment 1

[0023] As Figures 1 - 4 shown, a plastic particle granulator with a screening function proposed by the present utility model includes a screening box 1 and a crushing pipe 2. One side of the upper surface of the screening box 1 is fixedly connected with a crushing pipe 2. A bent pipe 7 is fixedly installed inside the crushing pipe 2, and the bent pipe 7 penetrates through the crushing pipe 2. Both ends of the bent pipe 7 are located inside and outside the crushing pipe 2 respectively. A double-shaft motor 15 is fixedly installed inside the bent pipe 7. The double-shaft motor 15 is located inside the crushing pipe 2. The ends of the two output shafts of the double-shaft motor 15 are respectively fixedly connected with a fan blade 14 and a disc 17. The top end of the disc 17 is conical to prevent waste rubber products from accumulating on the disc 17.

[0024] The fan blade 14 and the disc 17 are respectively located inside and outside the bent pipe 7. Crushing blades 16 are fixedly installed on the outer surface of the disc 17. The crushing blades 16 rotate at a high speed and crush waste rubber products into particles for use in plastic runways. A spring 11 is fixedly connected inside the screening box 1, and a sieve plate 12 is fixedly installed at the end of the spring 11. The sieve plate 12 maintains a certain inclination angle with the horizontal plane to facilitate the sliding of the particles on the sieve plate 12. And the bottom of the inner wall of the screening box 1 is at a certain inclination angle to facilitate the particles passing through the sieve plate 12 to slide out from the inside of the screening box 1. An outlet for discharging particles is provided on the side of the outer surface of the screening box 1 away from the crushing pipe 2. A vibrator 13 is fixedly installed on the lower surface of the sieve plate 12.

[0025] When the utility model is in use, waste rubber products are placed inside the crushing pipe 2. The double-shaft motor 15 drives the fan blades 14 and the crushing blades 16 to rotate. Then, the crushing blades 16 crush the waste rubber products into particulate matter for use in plastic runways. At the same time, the fan blades 14 rotate, causing outside air to enter the crushing pipe 2 from the elbow pipe 7 and blow towards the crushing blades 16, thereby playing a role in air-cooling and cooling the crushing blades 16, preventing rubber from melting and adhering to the outer surface of the crushing blades 16, improving the crushing and granulation efficiency, and prolonging the service life of the crushing blades 16. The particulate matter inside the crushing pipe 2 falls onto the sieve plate 12. The vibrator 13 drives the sieve plate 12 to vibrate, removing larger unqualified particulate matter through the sieve plate 12 and sliding out along the sieve plate 12 from the screening box 1. The particulate matter passing through the sieve plate 12 falls to the bottom of the inner wall of the screening box 1 and slides out of the screening box 1 to the outside.

Compared with Embodiment 1, this embodiment further includes a cutting box 4 fixedly installed on the upper surface of the crushing pipe 2. Inside the cutting box 4, rotating rollers 9 are symmetrically installed near the front and rear surfaces. A number of annular blades 10 are evenly and fixedly installed on the outer surfaces of the two rotating rollers 9. The annular blades 10 on the two rotating rollers 9 are distributed at intervals. Guide plates 5 are symmetrically and fixedly installed on the inner wall of the cutting box 4 near the front and rear surfaces, and the two guide plates 5 are respectively located above the two rotating rollers 9. The two guide plates 5 are conducive to waste rubber products entering between the two rotating rollers 9. A cutting motor 6 is fixedly installed inside the cutting box 4. The end of the output shaft of the cutting motor 6 is fixedly connected to one end of the rotating roller 9 near the inside of the cutting box 4. One end of each of the two rotating rollers 9 near the outside of the cutting box 4 is fixedly connected to a gear 8, and the two gears 8 are meshed with each other. A protective cover 3 is fixedly installed outside the cutting box 4, and the two gears 8 are both located inside the protective cover 3. The protective cover 3 plays a role in protecting the gears 8.

[0028] In this embodiment, the cutting motor 6 drives one of the rotating rollers 9 to rotate. The two rotating rollers 9 are driven by the meshed gears 8. After the waste rubber products are put into the cutting box 4, the rotating annular blades 10 cut them into strips to facilitate subsequent crushing by the crushing blades 16 and improve the granulation efficiency.
