Description

Technical Field

[0001] The utility model relates to the technical field of plastic granulation, in particular to a plastic particle uniform granulation device based on waste recycling. Background Technique

[0002] Plastic granulation is a process of plastic mechanical processing. In the process of plastic granulation, it is necessary to master skills according to the performance of the machine and practice exploration to continuously improve the quality processing of plastic products.

[0003] According to a disclosed plastic particle granulation device (publication number: CN221365329U), in the above application, plastic particles slide along the bottom wall of the cold water tank onto the receiving platform. The output shaft of the transfer motor drives the transfer shaft to rotate, the transfer shaft drives the transfer spiral blade to rotate, and the transfer spiral blade conveys the cooled plastic particles on the receiving platform to the feeding pipe, and then the plastic particles fall through the feeding pipe onto the screening plate. The plastic particles fall along the screening plate, and under the action of the screening net with gradually increasing pore diameters, the screening of plastic particles is realized, and the connected particles and long-strip plastic particles fall from the feeding trough.

[0004] This device realizes the screening of plastic particles by the free sliding of plastic particles on the screening plate. However, there are a large number of screening holes on the screening plate, and there will be a large resistance when the plastic particles slide, which may cause the plastic particles to accumulate on the screening plate, and then the subsequent falling plastic particles cannot pass through the screening of the screening plate, easily resulting in particles of different sizes passing through the feeding trough, which is not conducive to subsequent processing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] As Figures 1-4 shown, the present utility model provides a technical solution: a plastic granule uniform granulation device based on waste recycling, including an extruder 1, a discharge pipe 2 is fixedly installed on the side wall of the extruder 1, a water tank 3 is fixedly installed on the side wall of the extruder 1, the inside of the water tank 3 inclines towards the auger shaft 9, a servo motor 4 is fixedly installed on the outer wall of the discharge pipe 2, a rotating shaft 5 is fixedly installed at the output end of the servo motor 4, a cutting knife 6 is fixedly installed on the outer wall of the rotating shaft 5. By starting the servo motor 4 to drive the rotating shaft 5 to rotate, the long strip-shaped plastic extruded from the discharge pipe 2 of the extruder 1 can be cut by the rotation of the rotating shaft 5 in cooperation with the cutting knife 6, so that the strip-shaped plastic is divided into plastic granules and falls into the inside of the water tank 3 for cooling. A blanking pipe 7 is fixedly installed on the outer wall of the water tank 3, a DC motor 8 is fixedly installed on the top of the water tank 3, a auger shaft 9 is rotatably connected to the inner wall of the water tank 3, the top of the auger shaft 9 penetrates through the water tank 3 and is fixedly installed at the output end of the DC motor 8, and the penetration part of the auger shaft 9 and the water tank 3 is rotatably connected. By starting the DC motor 8 to drive the auger shaft 9 to rotate, the cooled plastic granules in the water tank 3 can be lifted to the blanking pipe 7, so that the plastic granules are discharged from the water tank 3 through the blanking pipe 7 and fall into the inside of the screening box 10. A screening box 10 is slidably connected to the outer wall of the water tank 3, a discharge port 11 is opened on the screening box 10, a sieve plate 12 is fixedly installed on the inner wall of the screening box 10, and sieve holes 13 are opened on the sieve plate 12. The sieve plate 12 and the sieve holes 13 inside the screening box 10 can be used to screen the plastic granules. The apertures of the sieve holes 13 are different, and the aperture of the sieve hole 13 is larger at the end closer to the discharge port 11. The plastic granules can be screened into plastic granules of different sizes by using the sieve holes 13 with different apertures. A shaking mechanism 14 for improving the screening effect is arranged on the water tank 3. By arranging the shaking mechanism 14, the plastic granules can be accelerated to slide downwards, so that the sieve holes 13 can fully screen the plastic granules, and prevent the plastic granules from accumulating on the sieve plate 12, resulting in uneven discharge of the plastic granules. A knocking mechanism 15 is arranged on the screening box 10. By arranging the knocking mechanism 15, the plastic granules stuck in the sieve holes 13 can be shaken out, preventing the plastic granules from blocking the sieve holes 13, so that the sieve plate 12 and the sieve holes 13 can fully screen the plastic granules.

[0024] The above-mentioned jitter mechanism 14 includes an eccentric wheel 141, an inclined groove 142, a sliding rod 143, a rectangular frame 144, and a ball head rod 145; the eccentric wheel 141 is fixedly installed on the outer wall of the auger shaft 9, the inclined groove 142 is opened at the top of the screening box 10, the sliding rod 143 is slidably connected to the inner wall of the water tank 3, and the sliding rod 143 penetrates through the water tank 3. Reciprocally pushing and pulling the sliding rod 143 by the rectangular frame 144 will cause the sliding rod 143 to slide reciprocally on the inner wall of the water tank 3. One end of the sliding rod 143 is fixedly installed with a rectangular frame 144, and the inner wall of the rectangular frame 144 fits against the outer wall of the eccentric wheel 141. While the auger shaft 9 is rotating, it will drive the eccentric wheel 141 to rotate synchronously. While the eccentric wheel 141 is rotating, it will reciprocally squeeze the rectangular frame 144, causing the rectangular frame 144 to reciprocally push and pull the sliding rod 143. The other end of the sliding rod 143 is fixedly installed with a ball head rod 145. The end of the ball head rod 145 away from the sliding rod 143 fits against the inner wall of the inclined groove 142. While the sliding rod 143 slides reciprocally on the inner wall of the water tank 3, it will drive the ball head rod 145 to reciprocally move synchronously along the inner wall of the inclined groove 142. At this time, the ball head rod 145 will reciprocally squeeze the inclined groove 142, thereby causing the screening box 10 to slide reciprocally on the outer wall of the water tank 3, so that the screening box 10 can drive the sieve plate 12 to reciprocally jitter. Through the reciprocal jitter of the sieve plate 12, the downward sliding of the plastic particles can be accelerated, and the sieve holes 13 can fully screen the plastic particles.

[0025] The above-mentioned knocking mechanism 15 includes a rotating rod 151, a spiral groove 152, a rubber rod 153, a steel ball 154, an inclined rod 155, and a guide rod 156; one end of the rotating rod 151 is rotatably connected to the inner wall of the screening box 10, and the other end of the rotating rod 151 penetrates through the screening box 10. The penetrating part of the rotating rod 151 and the screening box 10 is rotatably connected. A spiral groove 152 is opened on the rotating rod 151. A rubber rod 153 is fixedly installed on the outer wall of the rotating rod 151. A steel ball 154 is fixedly installed at the end of the rubber rod 153 away from the rotating rod 151. By the reciprocating rotation of the rotating rod 151 and the cooperation of the rubber rod 153, the steel ball 154 can be driven to repeatedly knock the bottom of the sieve plate 12. The outer wall of the steel ball 154 fits against the bottom of the sieve plate 12. By repeatedly knocking the sieve plate 12 with the steel ball 154, the plastic particles stuck inside the sieve holes 13 can be vibrated out, preventing the plastic particles from blocking the sieve holes 13, so that the sieve plate 12 and the sieve holes 13 can fully screen the plastic particles. An inclined rod 155 is fixedly installed on the outer wall of the water tank 3, and a guide rod 156 is fixedly installed on the outer wall of the inclined rod 155. The outer wall of the guide rod 156 fits against the inner wall of the spiral groove 152. While the screening box 10 slides reciprocally on the outer wall of the water tank 3, it will drive the rotating rod 151 to reciprocally move synchronously. While the rotating rod 151 is reciprocally moving, the guide rod 156 will reciprocally squeeze the spiral groove 152, thereby causing the rotating rod 151 to reciprocally rotate.

[0026] Working principle: By starting the servo motor 4 to drive the rotation of the rotating shaft 5, the long strip-shaped plastic extruded from the discharge pipe 2 of the extruder 1 can be cut through the rotation of the rotating shaft 5 in cooperation with the cutting knife 6, so that the strip-shaped plastic is divided into plastic particles and falls into the interior of the water tank 3 for cooling. Since the bottom of the water tank 3 is inclined, the plastic particles inside the water tank 3 will slide to the auger shaft 9. At this time, start the DC motor 8 to drive the rotation of the auger shaft 9. Through the rotation of the auger shaft 9, the cooled plastic particles inside the water tank 3 can be lifted to the feed pipe 7, so that the plastic particles are discharged from the water tank 3 through the feed pipe 7 and fall into the interior of the screening box 10. At this time, the sieve plate 12 and the sieve holes 13 inside the screening box 10 can be used to screen the plastic particles. At the same time, while the auger shaft 9 is rotating, it will drive the eccentric wheel 141 to rotate synchronously. While the eccentric wheel 141 is rotating, it will reciprocally squeeze the rectangular frame 144, causing the rectangular frame 144 to reciprocally push and pull the sliding rod 143, so that the sliding rod 143 slides reciprocally on the inner wall of the water tank 3. At the same time, the sliding rod 143 will drive the ball head rod 145 to fit and reciprocally move synchronously on the inner wall of the inclined groove 142. At this time, the ball head rod 145 will reciprocally squeeze the inclined groove 142, thereby causing the screening box 10 to slide reciprocally on the outer wall of the water tank 3, so that the screening box 10 can drive the sieve plate 12 to reciprocally vibrate. Through the reciprocal vibration of the sieve plate 12, the downward sliding of the plastic particles can be accelerated, enabling the sieve holes 13 to fully screen the plastic particles, avoiding the accumulation of plastic particles on the sieve plate 12 resulting in uneven discharge of plastic particles. Through the sieve holes 13 with different diameters on the sieve plate 12, the plastic particles can be screened into plastic particles of multiple different sizes, so that the discharge of plastic particles can be more uniform, which is beneficial to subsequent production.

[0027] While the screening box 10 slides reciprocally on the outer wall of the water tank 3, it will drive the rotating rod 151 to reciprocally move synchronously. While the rotating rod 151 is reciprocally moving, the guide rod 156 will reciprocally squeeze the spiral groove 152, thereby causing the rotating rod 151 to reciprocally rotate. Through the reciprocal rotation of the rotating rod 151 in cooperation with the rubber rod 153, the steel ball 154 can be driven to repeatedly strike the bottom of the sieve plate 12. By repeatedly striking the sieve plate 12 with the steel ball 154, the plastic particles stuck inside the sieve holes 13 can be shaken out, avoiding the blockage of the sieve holes 13 by plastic particles, so that the sieve plate 12 and the sieve holes 13 can fully screen the plastic particles.

However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
