Description

Technical Field

[0001] This utility model belongs to the field of plastic granule processing technology, specifically referring to a screening device for processing plastic running track granules. Background Technology

[0002] Plastic running tracks, also known as athletic tracks, are composed of polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU granules, pigments, additives, and fillers. They possess excellent wear resistance, ensuring the long-term stability of the track structure. Since plastic granules can vary in size during processing, sieving is necessary to guarantee the uniformity of their quality.

[0003] The patent with publication number CN221475763U discloses a screening mechanism for processing plastic track granules. By setting a vibration mechanism inside the screening box, the vibration mechanism can drive the vibrating frame to vibrate up and down, thereby using the screening screen plate inside the vibrating frame to vibrate and screen the plastic granules. The qualified plastic granules fall onto the surface of the guide plate below the vibrating frame. The guide plate guides and transports the plastic granules. At the same time, a dust removal mechanism blows gas onto the surface of the guide plate to remove dust and impurities from the plastic granules, thereby achieving the dust removal effect on the plastic granules.

[0004] However, the above-mentioned device can only screen a single batch of plastic granules at a time, and cannot screen multiple batches at the same time, resulting in low processing efficiency. Utility Model Content

[0007] Furthermore, a feed hopper is provided on one side wall of the screening chamber, and a discharge port is provided on the other side wall of the screening chamber.

[0008] Furthermore, the bottom wall of the material discharge trough is inclined, and the inclined bottom end of the material discharge trough is connected through to the side wall of the discharge pipe.

[0009] Preferably, a vacuum cleaner is installed on the top wall of the screening cylinder, and an air extraction pipe is connected to the vacuum cleaner, which passes through and extends into the top of the discharge pipe.

[0010] Preferably, the screening cylinder is provided with a limiting frame on its side wall. The limiting frames are symmetrically arranged on both sides of the discharge port. An insert plate is movably connected between the two sets of limiting frames, and the insert plate is located close to the discharge port.

[0011] Furthermore, the vibration support mechanism includes a guide rod and a vibration motor. The guide rod is vertically inserted through the support platform.

[0021] like Figure 1-4As shown, this utility model proposes a screening device for processing plastic track granules, including a support platform 1, a vibration support mechanism 2 mounted on the support platform 1, and a feeding and separating mechanism 3 connected to the vibration support mechanism 2. The feeding and separating mechanism 3 includes a screening cylinder 4 and a discharge pipe 5. The screening cylinder 4 is connected to the vibration support mechanism 2. The screening cylinder 4 has a screening chamber 6 and a discharge trough 7. The screening chamber 6 is located above the discharge trough 7. A screen plate 8 is provided between the screening chamber 6 and the discharge trough 7. Multiple sets of screen plates are provided for both the screening chamber 6 and the discharge trough 7. A feeding hopper 9 is provided on one side wall of the screening chamber 6, and a discharge port 10 is provided on the other side wall of the screening chamber 6. A limiting frame 13 is provided on the side wall of the screening cylinder 4. The limiting frames 13 are symmetrically arranged on both sides of the discharge port 10. Insert plates 14 are movably connected between the limit frames 13. The insert plates 14 are set near the discharge port 10. The bottom wall of the discharge trough 7 is inclined. The inclined bottom end of the discharge trough 7 is connected to the side wall of the discharge pipe 5. The discharge pipe 5 is vertically connected to the bottom wall of the screening cylinder 4. When screening plastic granules, the raw material is poured into the screening chamber 6 through the feed hopper 9. The vibration support mechanism 2 is started to vibrate the screening cylinder 4. At the same time, affected by the vibration, the raw material jumps and collides in the screening chamber 6. The qualified plastic granules fall into the discharge trough 7 through the screen plate 8 and slide into the discharge pipe 5 through the inclined bottom wall of the discharge trough 7 for collection. After screening is completed, the insert plates 14 are pulled upward to make the discharge port 10 leak out and the unscreened raw material is discharged from the discharge port 10.

During the raw material screening process, the vacuum cleaner 11 is activated, and the dust entering the discharge pipe 5 is extracted through the air extraction pipe 12 to reduce the impact of dust on the surrounding environment.

[0023] like Figure 1 and 2 As shown, the vibration support mechanism 2 includes a guide rod 15 and a vibration motor 16. The guide rod 15 is vertically mounted on the support platform 1. A limiting block 17 is provided at the bottom of the guide rod 15. The top of the guide rod 15 is connected to the bottom wall of the screening cylinder 4. A spring 18 is provided between the bottom wall of the screening cylinder 4 and the support platform 1. The spring 18 is sleeved on the guide rod 15. The vibration motor 16 is installed on the bottom wall of the screening cylinder 4. When the vibration motor 16 is started, the screening cylinder 4 is driven to vibrate. At the same time, the spring 18 and the guide rod 15 support the screening cylinder 4, which can speed up the screening efficiency.

[0024] like Figure 1 As shown, a movable groove 19 is provided through the upper part of the support platform 1, and the discharge pipe 5 is movably connected through the movable groove 19 to facilitate the placement and discharge of the discharge pipe 5.
