[0002] Plastic processing and molding technology is a core area of ​​polymer materials engineering, including injection molding, extrusion molding, blow molding, and calendering.

[0003] In plastic processing and molding, long-particle pelletizers are used to cut melt-extruded or injection-molded plastic strips into uniform pellets for easy subsequent transportation, storage, or reprocessing. Existing technology (Chinese patent application CN202411846619.4, filed on 2024-12-16) describes an anti-sticking masterbatch pelletizer. During use, it includes a pelletizer base, a pelletizing drive unit fixedly connected to the top of the base, a cutter fixed to the output end of the drive unit, and a masterbatch strip pressing and trimming module located in front of the base. The block includes a positioning outer frame, a combined inner shell, and a pressing plate. In this invention, the masterbatch strip first enters the masterbatch strip pressing and trimming module. The four pressing plates cover all areas of the masterbatch strip surface, which can completely treat the surface of the masterbatch strip and effectively trim the edge protrusions in each area of ​​the masterbatch surface. The surface-treated masterbatch strip continues to be transported to the heat treatment constraint module. Multiple constraint heat pipes perform multi-area, long-term heat treatment on the transported masterbatch strip, effectively pre-treating the masterbatch strip before cutting it into pellets, avoiding tailing and adhesion during masterbatch cutting, and allowing the cutter to stably cut the masterbatch strip at fixed points.

[0004] Although existing technologies can improve pelletizing efficiency and quality, during the operation, when the cutter cuts long pellets, a small number of pellets will stick to both sides of the cutter. This sticking causes uneven pellet size, affecting production efficiency and quality. Utility Model Content

[0005] The purpose of this invention is to provide a long-particle pelletizer that prevents sticking, so as to solve the problem of uneven particle size caused by the sticking of the cutter blades mentioned in the background art.

[0010] Furthermore, the second gear has more teeth than the first gear, and due to the difference in the number of teeth, the second gear rotates at a lower speed than the first gear.

[0011] Furthermore, the cutter is provided with limiting rails on both sides, and sliders are fixedly connected to both ends of the cutter. The inner wall of the limiting rail is provided with a groove whose internal size structure is consistent with the external size structure of the slider. At the same time, the cutter and the limiting rail form a sliding mechanism through the slider and the groove.

[0012] Furthermore, the linkage includes a first sprocket fixedly connected to the outer wall of the drive rod, one end of a chain being meshed with the outer wall of the first sprocket, a second sprocket being meshed with the inner wall of the other end of the chain, a first rotating rod being fixedly connected to the inner wall of the second sprocket, a third gear being fixedly connected to the outer wall of the first rotating rod, a fourth gear being meshed with the outer wall of the third gear, and a second rotating rod being fixedly connected to the inner wall of the fourth gear.

[0016] (1) The anti-sticking long grain pelletizer is equipped with a pelletizing assembly. The drive rod of the pelletizing assembly drives the turntable to rotate. The turntable drives the cutter to move up and down periodically through the connecting rod to cut the long grains. At the same time as the drive rod rotates, the first sprocket rotates synchronously. The first sprocket drives the first rotating rod to rotate through the chain and the second sprocket. The third gear and the fourth gear mesh to drive the second rotating rod to rotate synchronously, which in turn drives the scraper to rotate, quickly cleaning the particles stuck to the surface of the cutter. Through the action of centrifugal force, the particles are thrown into the collection chamber for collection, avoiding the particles from sticking to the cutter and effectively improving the pelletizing efficiency and pelletizing quality.

[0017] (2) The anti-sticking long grain pelletizer is equipped with a pelletizing chamber, a top cover and a cooling fan. The cooling fan can cool the long grains, effectively reducing the temperature of the long grains, thereby reducing the viscosity of the long grains and preventing the particles from sticking to the outer wall of the cutter, which would affect the pelletizing efficiency and pelletizing quality.

Figures 1-6 The present invention provides the following technical solution: a long grain pelletizer with anti-sticking function, including a frame 1, a control box 2 fixedly connected to one side surface of the frame 1, a pelletizing chamber 3 fixedly connected to the top surface of the frame 1, a top cover 4 installed on the top surface of the pelletizing chamber 3, a feed inlet 6 on one side of the pelletizing chamber 3, and a discharge outlet 7 on the other side of the pelletizing chamber 3.

[0026] The pelletizing chamber 3 is equipped with a pelletizing assembly 5, which includes a driving component that acts on the cutter 507 to perform pelletizing. The driving component also acts on a linkage component, which in turn acts on the scraper 516 to perform rotation.

[0027] A cooling fan 8 is provided on one side of the top cover 4.

[0028] Example 1: As Figures 1-6 The present invention provides the following technical solution: a long-particle pelletizer with anti-sticking capability, comprising a pelletizing component 5, as shown in the figure. Figure 5 As shown, a motor 501 is fixedly connected to one side surface of the frame 1. A first gear 502 is fixedly connected to the output end of the motor 501. A second gear 503 is meshed with the outer wall of the first gear 502. One end of a drive rod 504 is fixedly connected to the inner wall of the second gear 503. A turntable 505 is fixedly connected to the other end of the drive rod 504. One end of a connecting rod 506 is rotatably connected to one side surface of the turntable 505. A cutter 507 is rotatably connected to the other end of the connecting rod 506. Figure 5 As shown, the second gear 503 has more teeth than the first gear 502. Due to the difference in the number of teeth, the rotational speed of the second gear 503 is lower than that of the first gear 502. Figure 5 As shown, the cutter 507 has limiting rails 508 on both sides, and sliders are fixedly connected to both ends of the cutter 507. The inner wall of the limiting rails 508 has a groove whose internal dimensions match the external dimensions of the slider. The cutter 507, through the sliders and grooves, forms a sliding mechanism with the limiting rails 508. Figure 6As shown, a first sprocket 509 is fixedly connected to the outer wall of the drive rod 504. One end of a chain 510 is meshed with the outer wall of the first sprocket 509. A second sprocket 511 is meshed with the inner wall of the other end of the chain 510. A first rotating rod 512 is fixedly connected to the inner wall of the second sprocket 511. A third gear 513 is fixedly connected to the outer wall of the first rotating rod 512. A fourth gear 514 is meshed with the outer wall of the third gear 513. A second rotating rod 515 is fixedly connected to the inner wall of the fourth gear 514. Figure 6 As shown, scrapers 516 are fixedly connected to the outer walls of both the first rotating rod 512 and the second rotating rod 515. Multiple scrapers 516 are provided, and they are symmetrically distributed about the central axis of the first rotating rod 512 and the second rotating rod 515. A collection chamber 9 is provided outside the scrapers 516. Figure 6 As shown, air inlets are provided on both sides of the bottom of the pelletizing chamber 3, and dustproof nets are installed at the air inlets.

[0029] In operation, motor 501 drives the first gear 502 to rotate, which meshes with the second gear 503. The second gear 503 drives the drive rod 504 to rotate, which in turn drives the turntable 505 to rotate. The first gear 502 and the second gear 503 can be replaced according to the required cutting length to achieve a suitable speed ratio. The turntable 505 drives the cutter 507 to move up and down periodically via connecting rod 506 to cut long particles. The cutter 507 slides on the inner wall of the limiting rail 508 through the cooperation of the slider and the groove. The limiting rail 508 limits the movement of the cutter 507. At the same time, as the drive rod 504 rotates, it drives the first chain... The first sprocket 509 rotates synchronously, and the second sprocket 511 rotates synchronously via the chain 510. The second sprocket 511 is fixedly connected to the first rotating rod 512, causing the first rotating rod 512 and the third gear 513 to rotate synchronously. The third gear 513 meshes with the fourth gear 514, causing the second rotating rod 515 to rotate synchronously. This, in turn, causes the first rotating rod 512 and the second rotating rod 515 to rotate synchronously. The rotation of the scraper 516 quickly cleans the particles adhering to the surface of the cutter 507, and centrifugal force throws the particles into the collection chamber 9 for collection, preventing particles from sticking to the cutter 507 and effectively improving pelletizing efficiency and quality.

[0030] Example 2: Figures 1-6 The technical solution shown, based on Embodiment 1, further discloses a pelletizing chamber 3, a top cover 4, and a cooling fan 8. The pelletizing chamber 3 is fixedly connected to the top surface of the frame 1, and the top cover 4 is installed on the top surface of the pelletizing chamber 3. Figure 3 As shown, a cooling fan 8 is provided on one side of the top cover 4, such as... Figure 4As shown, air inlets are provided on both sides of the bottom of the pelletizing chamber 3, and dustproof nets are installed at the air inlets.

[0031] When the long grains enter the pelleting chamber 3 through the feed inlet 6, the cooling fan 8 can cool the long grains, effectively reducing their temperature and viscosity. This prevents the grains from sticking to the outer wall of the cutter 507 when it cuts them, thus affecting the pelleting efficiency and quality.
