Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plastic granulation, and in particular relates to a granulating mechanism for a plastic granulator. Background Art
[0002] Plastic granulator is mainly used for processing waste plastic film, woven bags, agricultural convenience bags, basins, barrels, beverage bottles, furniture, daily necessities, etc. It is suitable for most common waste plastics. It is the most widely used and popular plastic recycling processing machinery in the waste plastic recycling industry. Its principle is to use high-temperature melting, plasticizing and extrusion processes to change the physical properties of plastics to achieve plasticizing and cutting of plastics.
[0003] A plastic granulator granulating mechanism is disclosed in Chinese patent CN219276330U, which belongs to the technical field of plastic granulation. The plastic granulator granulating mechanism comprises a shell, and a cooling zone and a granulating zone are respectively provided at the left and right ends of the shell. A plurality of cooling pipes are inserted between the left and right side surfaces of the cooling zone. The right side surface of the granulating zone is rotatably connected with a rotating shaft, and a plurality of granulating knives are installed at the leftmost end of the rotating shaft. Heat conducting plates are provided at the left and right ends of the cooling zone, and the cooling pipes pass through the heat conducting plates at the left and right ends. A wire woven basket is welded on the top between the heat conducting plates at the left and right ends. A cover plate located directly above the wire woven basket is installed on the top of the cooling zone by screws, and an air intake fan is embedded on the cover plate.
[0004] After the plastic is extruded from the pelletizer, it is directly pelletized. At this time, the temperature of the plastic is still very high and it is soft. Therefore, when the plastic is pelletized, it is easy to stick to the knife, which affects the pelletizing of the plastic by the pelletizer. In addition, the pelletized plastic will stick together, affecting the processing quality of the plastic particles. In the above documents, the plastic strips are cooled and solidified in advance to avoid sticking to the knife and the plastic particles sticking to each other. However, the cut plastic particles are not screened, and some plastic particles are unqualified, affecting product quality.
[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0030] See also Figure 1-Figure 6 As shown, the utility model is a pelletizing mechanism for a plastic pelletizer, comprising a pelletizer 1, wherein the outer surface of the pelletizer 1 is provided with a motor 2 and a cutting assembly 3, a pelletizing assembly 4 is provided at the bottom of the cutting assembly 3, an adjusting assembly 5 and a limiting assembly 6 are provided on the outer surface of the pelletizing assembly 4, the cutting assembly 3 is used for cutting the plastic produced by the pelletizer 1, the pelletizing assembly 4 is used for screening plastic particles, the adjusting assembly 5 is used for adjusting the screening refinement degree of the pelletizing assembly 4, and the limiting assembly 6 is used for fixing the adjusting assembly 5.
[0031] Pour the waste plastic into the granulator 1, start the motor 2 to make the waste plastic move in the granulator 1 and melt it through the heating device in the granulator 1, and the melted waste plastic reaches the cutting component 3 on the right side of the granulator 1, and the cutting component 3 cuts the waste plastic strips into particles and drops them on the discharging component 4, and the particles of different sizes are screened through the discharging component 4, so that the limiting component 6 is separated from the discharging component 4 to release the limiting fixation of the adjusting component 5, and the adjusting component 5 can adjust the screening refinement degree of the discharging component 4.
[0032] The utility model connects the discharging component 4 and the adjusting component 5. After the plastic particles fall from the cutting component 3 onto the discharging component 4, the discharging component 4 vibrates to screen the plastic particles. Larger plastic particles cannot pass through the discharging component 4, so that they can only be discharged from the top of the discharging component 4, while smaller plastic particles pass through the discharging component 4 and are discharged from the bottom thereof. When the adjusting component 5 rotates, it drives the discharging component 4 to change the degree of screening refinement, thereby realizing the screening of plastic particles of different sizes, which is convenient for screening unqualified products.
[0033] In one embodiment, for the above-mentioned cutting component 3, the cutting component 3 includes a cylinder 301, the interior of the cylinder 301 is rotatably connected to a first rotating shaft 302, the first rotating shaft 302 is transmission-connected to a motor 2, a discharge barrel 303 is opened inside the cylinder 301, and a cutter 304 is fixedly connected to the outer surface of the rotating shaft 302.
[0034] After the motor 2 is started, it drives the first rotating shaft 302 to rotate, and the first rotating shaft 302 drives the cutter 304 to rotate.

[0035] In one embodiment, for the above-mentioned particle outlet component 4, the particle outlet component 4 includes a first sieve plate 401, the first sieve plate 401 is located below the cylinder 301, the bottom of the first sieve plate 401 is fixedly connected with a fixed shaft 402, a spring 405 and a vibration motor 407, the outer surface of the fixed shaft 402 is rotatably connected with a second sieve plate 403, the outer surfaces of the first sieve plate 401 and the second sieve plate 403 are both provided with sieve holes 404, and the end of the spring 405 is fixedly connected with a first leg 406.
[0036] The plastic particles cut out by the cutter 304 fall on the first sieve plate 401, and the vibration motor 407 is started to vibrate the first sieve plate 401 and the second sieve plate 402. The particles on the first sieve plate 401 that are larger than the sieve holes 404 are blocked and discharged from above the sieve plate 401 during the vibration process, and the particles that are smaller than the sieve holes 404 pass through the first sieve plate 401 and the second sieve plate 402 and are discharged from below the sieve plate 401. Through the arrangement of the first sieve plate 401 and the sieve holes 404, the plastic can be screened after being cut into particles to prevent unqualified products from mixing in and affecting product quality.

[0038] The rotating hand wheel 501 drives the second rotating shaft 502, and the second rotating shaft 502 drives the gear 503 to rotate. The gear 503 meshes with the gear ring 504 and drives the second sieve plate 403 to rotate. When the sieve holes 404 on the second sieve plate 403 are staggered at a certain angle from the sieve holes 404 on the first sieve plate 401, the range in which plastic particles can pass is reduced.

[0044] Through the above technical scheme, 1. Through the connection between the discharging component 4 and the adjusting component 5, after the plastic particles fall from the cutting component 3 onto the discharging component 4, the discharging component 4 vibrates to screen the plastic particles, and the larger plastic particles cannot pass through the discharging component 4, so that they can only be discharged from the top of the discharging component 4, while the smaller plastic particles pass through the discharging component 4 and are discharged from the bottom thereof. When the adjusting component 5 rotates, it drives the discharging component 4 to change the degree of screening refinement, thereby realizing the screening of plastic particles of different sizes, which is convenient for screening unqualified products. 2. Through the meshing of the gear 503 and the gear ring 504, when the rotating hand wheel 501 drives the second rotating shaft 502 and the gear 503 to rotate, the gear 503 drives the gear ring 504 and the second sieve plate 403 to rotate, so that the sieve holes 404 on the second sieve plate 403 are staggered at a certain angle with the sieve holes 404 on the first sieve plate 401. At this time, the interval in the sieve holes 404 for particles to pass through is reduced, so that the staff can adjust the degree of screening refinement of the first sieve plate 401 and the second sieve plate 403 according to the actual working conditions.
