Description

Technical Field

[0001] This utility model relates to the field of plastic machinery technology, and in particular to a granulation device for the production of nylon plastic granules. Background Technology

[0002] Currently, most nylon plastic granule drying methods use hot air circulation equipment, which has significant drawbacks: the risk of thermal degradation. Hot air directly contacts the material surface, and when the local temperature exceeds 160℃, it causes molecular chain breakage, hardening, and crust formation. The high-temperature airflow causes rapid dehydration and crystallization of the granule surface, forming a hard shell that hinders the diffusion of internal moisture, thus affecting subsequent processing. Traditional magnetic suction devices use bolts to fix the magnets, requiring the entire device to be stopped and disassembled for cleaning.

[0003] Problems exposed by linear vibrating screens in nylon particle screening: adhesion and clogging, electrostatic adsorption of nylon causing fine powder to stick to the screen holes, low classification efficiency, insufficient directional dispersion, and random vibration causing particles to jump around disorderly. Utility Model Content

The upper end of the directional wheel 6 is rotatably connected to both sides of the screen plate 7. A traction rod 8 is fixedly connected to the left side of the screen plate 7. The traction rod 8 is connected to the rotating shaft 9 through a crank-rocker mechanism. The rotating shaft 9 is slidably connected inside the bearing seat 11. The lower end of the bearing seat 11 is fixedly connected to the base frame 5. A second motor 13 is slidably fixedly connected to one side of the rotating shaft 9. A lower material discharge port 4 is fixedly connected to the lower end of the base frame 5.

[0025] The shredding chamber 15 is equipped with two shredding wheels 14. A rotating rod 16 is fixedly connected to the middle of each shredding wheel 14. The outer circumference of the left end of the rotating rod 16 passes through the left side of the shredding chamber 15 and is fixedly connected to a gear 17. A third motor 10 is slidably and fixedly connected to one side of the rotating rod 16.

[0026] Specifically, inside the shredding chamber 15, the third motor 10 is started, which drives the rear rotating rod 16 and gear 17 to rotate, which in turn drives the front rotating rod 16 and gear 17 to rotate, and then drives the front and rear shredding wheels 14 to rotate, thus crushing the nylon plastic granule raw material.

[0027] The heating rods 26 are evenly distributed around the periphery in the interlayer of the tank 23, and the interlayer is filled with heat-conducting oil to form a heat exchange cavity.

[0028] Specifically, the nylon plastic granule raw material is driven by the first motor 21 to drive the output shaft 22, which in turn drives the spiral blades 24 to rotate. The material is rapidly pushed forward at the feeding end, squeezed and turned, and the heating time is extended. The electric heating rod 26 heats the high-temperature heat-conducting oil in the jacket of the tank 23, and the heat is directly conducted to the granules through the stainless steel wall.

[0029] The top left side of the trough 23 is connected to the feed hopper 25. The trough 23 is located below the right end of the feed bin 27. The horizontal height of the trough 23 is higher than the horizontal height of the top of the feed bin 27.

[0030] Specifically, after drying, the nylon plastic granules slide into the feed hopper 27.

[0031] The magnet block 18 and the connecting rod 19 are slidably connected, and the end face of the magnet block 18 is lower than the horizontal height of the inlet of the feed hopper 27.

[0032] Specifically, when the dried nylon plastic granule raw material passes through the magnet block 18, the iron filings are strongly attracted.

[0033] The shredding chamber 15 penetrates the base 1 and is located below the screen plate 7. The lower end of the shredding chamber 15 is connected to the upper end of the screen plate 7.

[0034] Specifically, the crushed nylon plastic granules fall into the sieve plate 7 through the through-hole between the shredder 15 and the base 1.

[0035] The slag outlet 12 is fixedly connected to the right side of the sieve plate 7.

[0036] Specifically, the third motor 10 drives the screen plate 7 to swing, screening the nylon plastic granules. Smaller nylon plastic granules fall through the screen holes of the screen plate 7 to the discharge port at the bottom of the lower material discharge port 4, while larger nylon plastic granules are discharged and collected at the slag discharge port 12 through the vibration of the screen plate 7, and then crushed again. This achieves the screening and reprocessing of larger nylon plastic granules, avoiding affecting subsequent processing.

[0037] Working Principle: Wet plastic granules are fed into the tank 23 via a screw conveyor from the feed hopper 25. The first motor 21 drives the output shaft 22, which in turn rotates the screw blades 24. The material is rapidly advanced at the feed end, compressing and turning it to extend the heating time and conduct heat through contact. The heating rod 26 heats the high-temperature heat-conducting oil in the jacket of the tank 23. The heat is directly conducted to the granules through the stainless steel wall, causing the moisture to evaporate. After drying, the granules slide into the feed hopper 27. When they pass through the magnet block 18, the iron filings are strongly attracted, and the clean granules enter the shredding chamber 15. The second motor 13 drives the rotating rod 16 to rotate at high speed through the gear 17, causing the shredding wheel 14 to form a shearing surface with the shredding chamber 15, crushing the dried granules. The third motor 10 drives the rotating shaft 9, which in turn drives the screen plate 7 to swing horizontally through the crank rocker mechanism. Qualified granules pass through the screen plate 7 and fall into the lower material discharge port 4, while unqualified granules roll along the screen plate 7 into the slag discharge port 12. After collection, they re-enter the drying and crushing cycle until they meet the standards.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
