[0002] Plastic granulator extrusion granulation machine is a type of equipment widely used in the plastics processing industry. It is mainly used to turn molten plastic into granules through processes such as extrusion and cutting, so as to facilitate subsequent transportation, storage and reprocessing. Existing plastic granulator extrusion granulation machines usually include extrusion device, cutting device and receiving device.

[0003] Existing plastic granulator extrusion granulators have some problems in actual use. After working for a long time, plastic granules are easily left on the cutting blade. These residues can affect the cutting effect and even cause the cutting blade to become clogged, affecting production efficiency. The residues generated during the cutting process cannot be cleaned in time and tend to accumulate at the bottom of the equipment, which not only affects the cleanliness of the equipment but may also damage it. To address these issues, we have designed a plastic granulator extrusion granulator to provide an alternative technical solution. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-6 A plastic granule extrusion granulator includes a rectangular mounting frame 1, a transverse extrusion head 2 is provided at the middle position inside the rectangular mounting frame 1, a movable receiving groove 6 is provided at the top of the transverse extrusion head 2, and a moving mechanism for moving the receiving groove 6 is provided at one end of the top of the transverse extrusion head 2.

[0023] Vertical hydraulic cylinders 4 are fixed on both sides of the top of the rectangular mounting frame 1. A vertical pelletizing blade 3 is fixed at the output end of the vertical hydraulic cylinder 4. A rotatable rectangular scraper 5 is provided at both ends of the vertical pelletizing blade 3. A rotating mechanism for rotating the rectangular scraper 5 is provided on one side of the rectangular mounting frame 1.

[0024] The rotating mechanism includes a rectangular support frame 9, which is located near the rectangular mounting frame 1 and is fixedly connected to it. A second drive motor 10 is bolted to the top of the rectangular support frame 9. A vertical threaded rod 11 is fixed to the output end of the second drive motor 10. A vertical sliding plate 12 is threaded to the outer side of the vertical threaded rod 11. Both ends of the bottom of the vertical sliding plate 12 are rotatably connected to vertical transmission rods 14 via pins. The two vertical transmission rods 14 are symmetrically designed. A vertical rotating column 15 is rotatably connected to the bottom of the vertical transmission rod 14. A longitudinal rotating shaft 16 is fixed inside the bottom end of the vertical rotating column 15. The longitudinal rotating shaft 16 is located near the end of the rectangular scraper 5 and is fixedly connected to it.

[0025] Vertical light rods 13 are fixed at both ends of the bottom of the rectangular support frame 9. Circular through holes are opened at both ends of the vertical sliding plate 12. The vertical light rods 13 are located inside the circular through holes and are slidably connected to the vertical sliding plate 12 through the circular through holes. The circular through holes allow the vertical sliding plate 12 to slide vertically on the outside of the vertical light rods 13, thereby allowing the vertical light rods 13 to guide the vertical lifting trajectory of the vertical sliding plate 12.

[0026] The longitudinal rotation shaft 16 passes through the interior of the rectangular mounting frame 1 and is rotatably connected to the rectangular mounting frame 1 via a bearing, thereby enabling the longitudinal rotation shaft 16 to rotate inside the rectangular mounting frame 1, and enabling the rectangular scraper 5 to rotate around the longitudinal rotation shaft 16 as the center.

[0027] Here, the operation of the second drive motor 10 enables the vertical threaded rod 11 to rotate. The rotation of the vertical threaded rod 11 enables the vertical sliding plate 12 to slide vertically on the outside of the vertical smooth rod 13. The vertical sliding of the vertical sliding plate 12, through the vertical transmission rod 14, enables the vertical rotating column 15 to drive the longitudinal rotating shaft 16 to rotate, thereby enabling the rectangular scraper 5 to rotate toward one end of the vertical pelletizing blade 3, thereby enabling the rectangular scraper 5 to come into contact with the vertical pelletizing blade 3, so that the residue on the surface of the vertical pelletizing blade 3 can be scraped off. Through the rotation of the rectangular scraper 5, the bottom of the rectangular scraper 5 can better fit into the bottom slope of the vertical pelletizing blade 3.

[0028] The moving mechanism includes a U-shaped support frame 7, which is fixed to the top of the transverse extrusion head 2. A first drive motor 8 is bolted to the top of the U-shaped support frame 7. A rotating crank 17 is fixed to the output end of the first drive motor 8. A transverse transmission column 18 is rotatably connected to one end of the bottom of the rotating crank 17. The transverse transmission column 18 is close to one end of the receiving groove 6 and is rotatably connected to the receiving groove 6.

[0029] Rectangular guide blocks are fixed on both sides of the top of the transverse extruder 2, and rectangular guide grooves are opened on both sides of the bottom of the receiving groove 6. The transverse extruder 2 and the receiving groove 6 are slidably connected by the rectangular guide blocks and the rectangular guide grooves. The rectangular guide grooves and the rectangular guide blocks allow the receiving groove 6 to move on the top of the transverse extruder 2 so that the receiving groove 6 can move to the bottom of the vertical pelletizer 3.

[0030] Here, the operation of the first drive motor 8 enables the U-shaped support frame 7 to rotate. The rotation of the U-shaped support frame 7 causes the receiving trough 6 to reciprocate at the top of the transverse extrusion head 2 via the transverse transmission column 18. When the vertical pelletizer 3 rises and falls to the top of the transverse extrusion head 2, the receiving trough 6 moves to the bottom of the vertical pelletizer 3, allowing the residue on the surface of the vertical pelletizer 3 to fall into the interior of the receiving trough 6, so that the residue can be collected.

[0031] Two rotatable rectangular scrapers 5 can scrape off residual plastic particles on the vertical pelletizing blade 3 when it rises, effectively avoiding the problem of clogging of the vertical pelletizing blade 3 caused by residue accumulation, ensuring the continuity and stability of the cutting process, thereby improving production efficiency. A reciprocating receiving groove 6 is set at the top of the transverse extrusion head 2, which can collect the scraped residue, preventing the residue from accumulating at the bottom of the equipment, keeping the equipment clean, reducing the workload of manual cleaning, and also reducing the risk of equipment damage caused by residue accumulation.

[0032] Working principle: The operation of the second drive motor 10 enables the vertical threaded rod 11 to rotate. The rotation of the vertical threaded rod 11 enables the vertical sliding plate 12 to slide vertically on the outside of the vertical smooth rod 13. The vertical sliding of the vertical sliding plate 12, through the vertical transmission rod 14, enables the vertical rotating column 15 to drive the longitudinal rotating shaft 16 to rotate, thereby enabling the rectangular scraper 5 to rotate toward one end of the vertical pelletizing blade 3, thereby enabling the rectangular scraper 5 to come into contact with the vertical pelletizing blade 3, so that the residue on the surface of the vertical pelletizing blade 3 can be scraped off. Through the rotation of the rectangular scraper 5, the bottom of the rectangular scraper 5 can better fit with the bottom slope of the vertical pelletizing blade 3.

[0033] The operation of the first drive motor 8 enables the U-shaped support frame 7 to rotate. The rotation of the U-shaped support frame 7, through the transverse transmission column 18, enables the receiving trough 6 to reciprocate at the top of the transverse extrusion head 2. When the vertical pelletizer 3 rises and falls to the top of the transverse extrusion head 2, the receiving trough 6 can move to the bottom of the vertical pelletizer 3, so that the residue on the surface of the vertical pelletizer 3 can fall into the interior of the receiving trough 6, and the residue can be collected.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
