[0026] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0027] like Figures 1-5As shown in the figure, the plastic pelletizer of this utility model includes a processing box 1 and a pelletizing assembly 6. The processing box 1 has a feed inlet 2 on the left outer wall and a discharge outlet 13 at the bottom. A partition 3 is fixedly installed on the left inner wall of the processing box 1. A drive motor 4 is fixedly installed on the right front outer wall of the processing box 1. The left outer wall of the processing box 1 has symmetrical arc grooves 5. The right inner side of the processing box 1 has symmetrical pelletizing assemblies 6. The left inner side of the processing box 1 has symmetrical guide assemblies 7. The guide assemblies 7 have a transmission belt 8 and a support rod 9 behind them. The guide assemblies 7 are connected to the pelletizing assembly 6 via the transmission belt 8. An electric push rod 10 is fixedly installed on the rear outer wall of the processing box 1. A vertical rod 11 is fixedly connected to the telescopic end of the electric push rod 10. Both ends of the vertical rod 11 are fixed with protrusions 12 near the support rod 9. The protrusions 12 are connected to the adjacent support rod 9.

[0028] As a preferred embodiment, based on the above structure, the pelletizing assembly 6 further includes a first horizontal shaft 61, pelletizing blades 62, a gear 63 and a first pulley 64. The first horizontal shaft 61 is bearing mounted on the inner right side of the processing box 1. Multiple pelletizing blades 62 are fixedly arranged in a ring on the outer wall of the first horizontal shaft 61. The gear 63 and the first pulley 64 are fixedly sleeved on the outer rear end of the first horizontal shaft 61.

[0029] As a preferred embodiment, based on the above structure, the upper and lower gears 63 mesh with each other, the front end of the lower first horizontal shaft 61 is fixedly connected to the output end of the drive motor 4, and the two sets of pelletizing components 6 are linked together and rotate in opposite directions.

[0030] In this embodiment, when the drive motor 4 is started to control the rotation of the lower first horizontal shaft 61, the upper first horizontal shaft 61 can be controlled to rotate synchronously by using two meshing gears 63, and the rotation directions of the two first horizontal shafts 61 are opposite to each other, which facilitates the rapid pelleting of the plastic strip fed between the two sets of pelletizing components 6.

[0031] As a preferred embodiment, based on the above structure, the centers of the two arc-shaped grooves 5 are further aligned with the center lines of the two first horizontal axes 61.

[0032] In this embodiment, the arc-shaped groove 5 facilitates the stable rotation and adjustment of the material guiding assembly 7.

[0033] As a preferred embodiment, based on the above structure, the material guiding assembly 7 further includes a second horizontal shaft 71, a conveying wheel 72, and a second pulley 73. The two ends of the second horizontal shaft 71 are respectively guided and slidably located in the front and rear arc-shaped grooves 5. Multiple conveying wheels 72 are fixed at equal intervals along the length direction on the outer side of the second horizontal shaft 71. The multiple conveying wheels 72 are spaced apart from multiple partitions 3. The second pulley 73 is fixedly sleeved on the outer rear end of the second horizontal shaft 71.

[0034] As a preferred embodiment, based on the above structure, the second pulley 73 and the first pulley 64 have the same diameter, the two ends of the transmission belt 8 are respectively sleeved on the outside of the second pulley 73 and the first pulley 64, the two ends of the support rod 9 are respectively bearing sleeved on the outer rear ends of the first horizontal shaft 61 and the second horizontal shaft 71, and the support rod 9 has a through groove structure inside.

[0035] In this embodiment, when the upper and lower pelletizing components 6 are controlled to rotate in opposite directions, the two transmission belts 8 can also be used to control the two material guiding components 7 to rotate synchronously in opposite directions, which makes it easier to press and guide the plastic strip clamped between the two material guiding components 7, and avoid the plastic strip from becoming skewed or broken during pelletizing.

[0036] As a preferred embodiment, based on the above structure, the two protruding pillars 12 are further guided to slide in the through groove structure located inside the two support rods 9.

[0037] In this embodiment, by controlling the horizontal movement of the vertical rod 11 through the electric push rod 10, the two protruding pillars 12 can respectively squeeze and push the two support rods 9 to drive the two sets of material guiding components 7 to rotate around the upper and lower first horizontal axes 61, thereby realizing the adjustment of the distance between the two sets of material guiding components 7, which is convenient for the stable clamping and guiding of plastic strips of various sizes.

[0038] The working principle of this utility model is as follows:

[0039] In use, firstly, several plastic strips to be granulated are inserted between multiple partitions 3 through the feed port 2 and fed between the upper and lower conveyor wheels 72. At this time, the vertical rod 11 can be moved horizontally to the left by the retraction of the electric push rod 10. The protrusions 12 at both ends of the vertical rod 11 squeeze and push the two support rods 9 to drive the two sets of material guiding components 7 to rotate in opposite directions around the upper and lower first horizontal axes 61. At this time, the second horizontal axis 71 can move along the arc groove 5, which can realize the adjustment of the distance between the two sets of material guiding components 7, and facilitate the stable clamping of plastic strips of various sizes.

[0040] Then, the drive motor 4 is turned on. The two meshing gears 63 can control the two sets of pelletizing components 6 to rotate synchronously in opposite directions. The two transmission belts 8 can also control the two sets of material guiding components 7 to rotate synchronously in opposite directions. This makes it easy to press the plastic strip clamped between the two sets of material guiding components 7 and guide it towards the two sets of pelletizing components 6. The two first horizontal shafts 61 rotating in opposite directions and the pelletizing blades 62 on their outer sides can quickly pelletize the fed plastic strip. Finally, the plastic pellets can be discharged from the device through the discharge port 13 for easy collection.

[0041] Compared with the prior art, this device utilizes two sets of material guiding components 7 during the pelletizing process to ensure that the plastic strip is always clamped, limited, and guided, thus preventing the plastic strip from becoming skewed or broken during pelletizing. Moreover, the pelletizing process of this device is carried out inside the processing box 1, which has a shielding and protective effect, preventing plastic particles from splashing during pelletizing, and also facilitating the quick collection of plastic particles.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
