[0001] This utility model relates to the field of drying and stirring technology for plastic pellet mills, and in particular to a drying and stirring assembly for plastic pellet mills. Background Technology
[0002] With the rapid development of technology, drying and mixing components for plastic pellet mills are key parts in the plastic recycling and processing process. They are mainly used to dry and uniformly mix plastic pellets. These components ensure the continuity of plastic pelleting, providing timely access to dry plastic pellet raw materials for production, thereby increasing production efficiency and reducing scrap rates. The use of drying and mixing components can effectively prevent these problems from occurring and improve the product qualification rate.
[0003] In the use of drying and mixing components in common plastic pellet mills, heating devices are installed on the inner wall of the device. However, this drying method cannot heat and dry the material evenly, which easily leads to uneven heating of the material surface, thereby reducing drying efficiency and the practicality of the device. Utility Model Content

[0005] Therefore, this utility model provides a drying and stirring assembly for a plastic granulator, comprising a main body, the main body including an outer shell, a shell cover mounted on the upper surface of the outer shell, a drying mechanism mounted on the upper surface of the shell cover, the drying mechanism including a connecting pipe mounted on the upper surface of the shell cover, a stirring mechanism mounted on the upper surface of the shell cover, the stirring mechanism including a motor, the lower surface of the motor being fixedly connected to the upper surface of the shell cover, a rotating shaft being fixedly connected to the output end of the motor, a spiral blade being fixedly connected to the surface of the rotating shaft, a first fixing plate being fixedly connected to the inner wall of the outer shell, and a second fixing plate being fixedly connected to the surface of the first fixing plate.
[0006] Preferably, the surface of the second fixing plate is provided with a third through hole, and a bearing is fixedly connected to the inner bottom of the outer shell, the surface of the bearing being movably connected to the end of the rotating shaft.
[0007] Preferably, the surface of the outer shell is provided with a first through hole, the inner wall of the first through hole is fixedly connected to a filter plate, the surface of the filter plate is provided with a fourth through hole, and the connecting pipe is located above the filter plate.
[0008] Preferably, a support mechanism is installed on the surface of the outer shell, the support mechanism includes a connecting ring, the inner wall of the connecting ring is fixedly connected to the surface of the outer shell, and a foot is fixedly connected to the lower surface of the connecting ring.
[0009] Preferably, a connecting mechanism is installed on the surface of the outer shell. The connecting mechanism includes a connecting shell, the surface of which is fixedly connected to the surface of the outer shell, and a first groove is formed on the lower surface of the connecting shell.
[0010] Preferably, a vibrating rod is fixedly connected to the lower surface of the connecting shell, a second through hole is opened on the surface of the shell, a connecting plate is fixedly connected to the surface of the shell, a cylinder is installed on the lower surface of the connecting plate, a lifting plate is fixedly connected to the output end of the cylinder, and the lifting plate is movably connected inside the connecting shell.
[0011] The beneficial effects of this utility model are:
[0012] (1) During use, the material to be stirred is placed inside the device, the motor is started, and the motor drives the fixed shaft at its output end to rotate. The spiral blades fixed on the surface of the shaft rotate accordingly, stirring the material located at the bottom of the shell upwards, so that the material is mixed evenly. At the same time, dry hot air is introduced into the connecting pipe fixed on the right side of the shell cover. When the hot air enters the inside of the shell, part of it is blocked by the second fixed plate, so that the hot air moves towards the bottom of the shell along the direction of the second fixed plate, so that the inside of the shell is heated evenly. After rising along the direction of the second fixed plate on the other side, it is discharged from the connecting pipe on the left side. The other part will be sprayed out from the third through hole with a gradually narrowing width opened on the second fixed plate, making full contact with the material and improving the drying efficiency. Compared with conventional devices, which have heating devices set on the inner wall of the device, but this drying method cannot heat and dry the material evenly, it is easy to produce uneven heating on the surface of the material, thereby reducing the drying efficiency and reducing the practicality of the device. This device can achieve rapid heating and can dry the surface of the material evenly, thus improving the practicality of the device.
[0013] (2) During use, the inner bottom of the connecting shell is a slope that slopes towards the outer shell, which facilitates the flow of material from the connecting shell into the interior of the outer shell. When the amount of material inside the outer shell is saturated, the cylinder fixed on the lower surface of the connecting plate is activated, and the cylinder drives the lifting plate to descend, covering the second through hole. At this time, the material inside the connecting shell no longer enters the interior of the outer shell, improving the practicality of the device. Attached Figure Description

[0022] Example 2:
[0023] Depend on Figures 1-4As shown, this utility model provides a drying and stirring assembly for a plastic granulator. A third through hole 206 is provided on the surface of the second fixed plate 205. A bearing 207 is fixedly connected to the inner bottom of the outer shell 101, and the surface of the bearing 207 is movably connected to the end of the rotating shaft 202. A first through hole 103 is provided on the surface of the outer shell 101, and a filter plate 301 is fixedly connected to the inner wall of the first through hole 103. A fourth through hole 302 is provided on the surface of the filter plate 301. A connecting pipe 303 is located above the filter plate 301.

The material flows into the bottom of the outer shell 101. A first groove 502 is provided on the lower surface of the connecting shell 501. A vibrating rod 503 is fixedly connected to the lower surface of the connecting shell 501. The vibrating rod 503 can use vibration to allow the material to enter the interior of the outer shell 101 more smoothly.

When the hot air enters the interior of the outer shell 101, part of it is blocked by the second fixed plate 205, causing the hot air to move towards the bottom of the inner shell 101 along the direction of the second fixed plate 205, so that the interior of the outer shell 101 is heated evenly, and then moves along the other side of the second fixed plate. After rising in the direction of 205, it is discharged from the connecting pipe 303 on the left. Another part will be sprayed out from the third through hole 206 with a gradually narrowing width opened on the second fixed plate 205, which fully contacts the material and improves the drying efficiency. The inner bottom of the connecting shell 501 is a slope that is inclined towards the outer shell 101, which facilitates the material to flow from the connecting shell 501 into the interior of the outer shell 101. When the amount of material inside the outer shell 101 is saturated, the cylinder 504 fixed on the lower surface of the connecting plate 104 is activated.
