[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 4In the utility model, a plastic pelletizing device for a plastic pelletizing machine comprises a processing box 1, an arc-shaped groove 2 is provided inside the processing box 1, a uniformly distributed feeding groove 3 is provided on the top of the processing box 1, and the bottom end of the feeding groove 3 is communicated with the inside of the arc-shaped groove 2, a driving motor 4 is fixedly installed on the front of the processing box 1, and a uniformly distributed partition 5 is fixedly connected to the output shaft of the driving motor 4, a hot air blower 6 is installed on the left side of the processing box 1, and the hot air blower 6 is communicated with the inside of the arc-shaped groove 2 through a pipeline, and a pelletizing motor 7 is fixedly installed on the inner wall of the arc-shaped groove 2, and the pelletizing motor 7 is fixedly installed on the inner wall of the arc-shaped groove 2. A pelletizing blade 8 is fixedly mounted on the output shaft of the machine 7, evenly distributed mounting grooves 9 are provided inside the processing box 1, evenly distributed movable grooves 10 are provided on the inner wall of the feeding trough 3, the movable grooves 10 are communicated with the inside of the mounting grooves 9, a power supply electromagnet 11 is installed on the inner wall of the mounting grooves 9, a movable shaft 12 is slidably mounted inside the movable groove 10, a magnetic block 13 is installed on the movable shaft 12, the magnetic block 13 is magnetically connected to the power supply electromagnet 11, a roller 14 is rotatably connected to the end of the movable shaft 12, and a discharge assembly 15 is provided at the bottom of the processing box 1;

[0023] The discharge assembly 15 includes a lower hopper 1501, which is fixedly installed at the bottom of the processing box 1, and the top of the lower hopper 1501 penetrates and extends to the inside of the arc-shaped groove 2. A push rod 1502 is fixedly installed at the bottom of the lower hopper 1501, and the top of the push rod 1502 penetrates and extends to the inside of the lower hopper 1501. The top of the push rod 1502 is fixedly connected with a material guide seat 1503, and the material guide seat 1503 is slidably connected to the inner wall of the lower hopper 1501;

[0024] The top shape of the material guiding seat 1503 is inclined from top to bottom toward both sides.

[0025] When it is necessary to pelletize the plastic rods before granulation, the user controls the internal settings of the processing box 1 to operate, the hot air blower 6 heats the external airflow and sends it into the arc groove 2, so that the temperature inside the arc groove 2 rises, the driving motor 4 drives the multiple groups of partitions 5 fixedly connected thereto to rotate synchronously, and the multiple groups of air holes on the partition 5 can realize the free flow of air, the pelletizing motor 7 is powered on and drives the pelletizing blade 8 fixedly connected thereto to rotate synchronously, at this time the state of the discharge assembly 15 is that the push rod 1502 pushes the material guide seat 1503 to the highest position, and the material guide seat 1503 seals the lower hopper 1501, then the user feeds the plastic rod from the top of the feeding trough 3, the bottom side of the plastic rod contacts with the multiple groups of rollers 14, and the movable shaft 12 moves inside the movable groove 10 during the downward pressing process, and the power electromagnet 11 generates a force that is opposite to the magnetic block 13. The same magnetic field causes the magnetic block 13 to push the moving shaft 12 so that the roller 14 has a certain limiting effect on the plastic rod, but the plastic rod still keeps moving slowly downward due to the gravity. When the bottom end of the plastic rod passes through the feeding trough 3 and enters the arc groove 2, it will contact the cutting blade 8, and then the blade cuts the plastic rod. As the plastic rod continues to fall, the plastic rod can be pelletized, and the pelletized material goes downward between the two groups of partitions 5. As the partition 5 rotates, it keeps turning and rolling. The plastic pellets are kept dry in the high-temperature arc groove 2. The user can continuously feed the plastic rods through multiple groups of feeding troughs 3 to complete the pelletizing. After drying, the push rod 1502 drives the guide seat 1503 to move downward. As the partition 5 pushes the plastic pellets, they enter the lower hopper 1501 and then are discharged from the lower hopper 1501 along the guide seat 1503.

[0026] In the utility model, multiple groups of feeding troughs 3 are provided to realize simultaneous feeding of multiple groups of plastic rods, and the horizontally rotating pelletizing blades 8 can pelletize multiple groups of plastic rods at the same time, thereby improving the pelletizing efficiency. The structure is compact and efficient. At the same time, multiple groups of perforated partitions 5 are provided to continuously rotate inside the arc groove 2 to make the plastic pellets roll and flip, thereby improving the drying efficiency of the plastic pellets, facilitating the subsequent pelletizing of the pelletizer, and the discharge component 15 can extend the drying time of the plastic pellets while reducing heat loss.

[0027] See also Figure 1 , wherein: a control panel 16 is fixedly installed on the processing box 1 , and the hot air blower 6 , the pelletizing motor 7 , the driving motor 4 , the power supply electromagnet 11 and the discharge assembly 15 are all electrically connected to the control panel 16 .

[0028] In the present invention, the setting of the control panel 16 allows the user to operate the device more simply and quickly, thereby reducing the steps required for the user to operate, thereby improving the pelletizing efficiency of the plastic.

[0029] See also Figure 2, wherein: a filter screen 17 is installed on the inner wall of the arc groove 2, and the filter screen 17 is located on the right side of the pipeline of the hot air blower 6.

[0030] In the present invention, the filter screen 17 can protect the pipe of the hot air blower 6 and prevent the rolling plastic particles from splashing into the pipe and causing the hot air blower 6 to be blocked.

[0031] See also Figure 2 and 3 , wherein: a limiting ring 18 is fixedly connected to the movable shaft 12 , and the limiting ring 18 is located inside the mounting groove 9 .
