The drying fan is arranged at the feed port of the pelletizer housing, which can not only reduce the moisture on the surface of the plastic pellets, but also cool the pellets again, so that the plastic pellets are not easy to clump or stick together;

[0004] However, in the existing pelletizer, when the staff is cleaning the inside of the casing, if the motor is accidentally touched, the gear cutter roller will rotate, which will injure the staff. When discharging the material, the cut pellets are dried by the drying structure, but the pellets fall quickly and the drying effect of the pellets is poor. Therefore, we propose a pelletizer with a safety protection structure to solve the above problems. Utility Model Content

Detailed Description of the Preferred Embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1: Please refer to Figure 1 , Figure 3 and Figure 5 . For the existing granulator, when the staff cleans the inside of the housing 1 and accidentally touches the motor 5, causing the gear cutter roller 8 to rotate, it will harm the staff. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0030] A granulator with a safety protection structure, a cleaning door 20 is installed at the front end of the housing 1 through a hinge, a motor 5 is installed at the rear of the housing 1, a pulley 6 is fixed to the output end of the motor 5, and a conveyor belt 7 is arranged outside the pulley 6. A gear cutter roller 8 is fixed to the front side of the pulley 6 at the output end of the motor 5, and a limiting roller 9 penetrates through the inside of the gear cutter roller 8. The connection mode between the limiting roller 9 and the housing 1 is snap connection;

[0031] When the casing 1 needs to be cleaned, start the motor 5. The motor 5 drives the gear cutter roller 8 to rotate until the holes in the gear cutter roller 8 are aligned with the holes at the rear end of the casing 1. Then rotate the cleaning door 20 to open the casing 1. Insert the limiting roller 9 into the holes of the gear cutter roller 8. The rear end of the limiting roller 9 is snapped into the rear end of the casing 1 to limit the gear cutter roller 8 and prevent accidental contact with the motor 5, which may cause the gear cutter roller 8 to rotate. The limiting roller 9, the gear cutter roller 8 and the casing 1 form a safety protection structure;

[0032] Embodiment 2: In the existing pelletizer, when discharging, the cut pellets are dried by a drying structure. However, the pellets fall rapidly, and the drying effect of the pellets is poor. To solve this technical problem, the following technical content is disclosed in this embodiment. Please refer to Figures 1 - 5 ;

[0033] A feed cover 2 is provided at the left end of the casing 1, and a first receiving shaft 3 is fixed inside the casing 1. A second receiving shaft 4 is arranged above the first receiving shaft 3, and a guide plate 10 fixed inside the casing 1 is arranged below the first receiving shaft 3. A drying casing 14 is fixed to the right side of the casing 1, and a heating plate 15 is installed at the right end of the drying casing 14. A stirring rod 16 is rotatably installed inside the drying casing 14, and a shielding cover 17 is rotatably installed at the bottom end of the drying casing 14. A docking plate 18 is fixed to the outer side of the bottom end of the drying casing 14, and a plug rod 19 passes through the inside of the docking plate 18. The second receiving shaft 4 is rotatably installed inside the casing 1. A stirring rod 16 is fixed to the front side of the pulley 6 at the bottom end of the conveyor belt 7. The inside of the shielding cover 17 is engaged with the plug rod 19, and the left end of the shielding cover 17 is limited to the drying casing 14 through the plug rod 19. The right end of the guide plate 10 is fixed to the left end of the drying casing 14, and both the front and rear ends of the drying casing 14 are of a porous structure. The drying casing 14 is communicated with the casing 1;

[0034] The material enters the inside of the casing 1 from the feed cover 2. The material is located between the first receiving shaft 3 and the second receiving shaft 4. The motor 5 drives the pulley 6, the conveyor belt 7, the gear cutter roller 8 and the stirring rod 16 to rotate. The gear cutter roller 8 cuts the material during rotation, and the gear cutter roller 8 drives the material to move to the right when cutting the material, so that the second receiving shaft 4 rotates;

[0035] The cut pellets fall onto the guide plate 10 and then fall into the inside of the drying casing 14 from the guide plate 10. The rotation of the stirring rod 16 stirs the pellets, and the heating plate 15 heats the pellets inside the drying casing 14 to dry the pellets. After the pellets are dried for a period of time, pull out the plug rod 19 inside the shielding cover 17 and the docking plate 18 to the left, and then flip the shielding cover 17 to unload the pellets inside the drying casing 14 to ensure the drying effect of the pellets;

[0036] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 2. When the existing pelletizer is cooled, dust will be introduced into the casing 1, which is inconvenient for dust blocking. To solve this technical problem, the following technical content is disclosed in this embodiment, as Figure 1 , Figure 3 and Figure 5 shown;

[0037] An installation ring 11 is fixed to the top end of the casing 1. A fan 12 is installed at the bottom end of the installation ring 11, and a dust-proof plate 13 is fixed to the top end of the installation ring 11. During the cutting process, the fan 12 is started. Under the action of the fan 12, external air enters the interior of the casing 1, enabling the gear cutter roller 8 to dissipate heat quickly. The dust-proof plate 13 blocks the dust in the air, preventing dust from entering the interior of the casing 1;

[0038] The above completes a series of operations of the pelletizer with a safety protection structure. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
