[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 7 , an embodiment provided by the present invention: a stirring device for PE film production, including an outer cylinder body 1, an inner cylinder body 12, and a variable volume component. The variable volume component is fixedly installed at the bottom of the inner wall of the outer cylinder body 1, and the inner cylinder body 12 is fixedly installed at the top of the outer wall of the variable volume component. The variable volume component is used to change the stirring volume between the outer cylinder body 1 and the inner cylinder body 12; The variable volume component includes: a first hydraulic lifting pump 13, a first lifting rod 14, and the inner cylinder body 12; The first hydraulic lifting pump 13 is fixedly installed at the bottom of the inner wall of the outer cylinder body 1, the first lifting rod 14 is fixedly installed at the top of the outer wall of the first hydraulic lifting pump 13, the inner cylinder body 12 is fixedly installed at the top of the outer wall of the first lifting rod 14. The outer wall of the inner cylinder body 12 is in contact with the inner wall of the outer cylinder body 1, and the top edge of the inner wall of the inner cylinder body 12 is designed in a pointed chamfer shape.

The raw materials enter through the flow valve 33. The photoelectric sensors 32 on both sides of the flow valve 33 detect the feeding flow rate of the raw materials in real time. The photoelectric sensors 32 transmit the flow rate data into the flow calculator 31, and the raw material flow rate is calculated according to the preset program in the flow calculator 31. At the same time, the infrared bin sensor 35 in the outer cylinder 1 detects the bin height of the raw materials in the outer cylinder 1 in real time. The flow calculator 31 and the infrared bin sensor 35 transmit the real-time collected bin data to the first hydraulic lifting pump 13. The first hydraulic lifting pump 13 is started according to the bin height and the feeding flow rate. The first hydraulic lifting pump 13 drives the first lifting rod 14 to move up and down. The first lifting rod 14 drives the inner cylinder 12 to move up and down. The inner cylinder 12 pushes the lower stirring drum 10 to stretch out or retract into the upper stirring drum 9, changing the stirring volume formed between the inner cylinder 12 and the outer cylinder 1 to adapt to the stirring requirements of different amounts of raw materials, ensuring that the volume is sufficient to make the raw material stirring more thorough, preventing excessive raw materials from causing too much stirring pressure, and preventing the raw materials from being stirred incompletely resulting in too large particles and too thick PE film produced, which affects the use; at the same time, the outer wall of the moving inner cylinder 12 is closely attached to the inner wall of the outer cylinder 1. During the upward movement, the edge of the inner cylinder 12 can remove the raw material slag attached to the inner wall of the outer cylinder 1, playing a cleaning role and improving the raw material utilization rate.

The multi-functional components installed on the high-speed rotating upper stirring drum 9 and lower stirring drum 10 are unfolded under the action of centrifugal force. Under the centrifugal action, the stirring rod 28 is flung outwards. The stirring rod 28 drives the ring sleeve seat 25 to rotate around the limit rod 24 installed on the fixed frame 23. The limit top plate 27 plays a limiting role to prevent the stirring rod 28 from being flung upwards excessively, resulting in insufficient stirring of the raw materials; the crushing blades 43 installed on the unfolded stirring rod 28 cut and stir the raw materials, ensuring that large particles of the raw materials become small particles under the impact and cutting of high-speed rotation, preventing the raw materials from caking and piling up, improving the crushing degree of the raw materials, and ensuring that the raw material specifications meet the production standards.

At this time, the air pump 26 is started, and the air pump 26 injects compressed air into the compression channel 42. The compressed air in the compression channel 42 pushes the connecting rod 29 out of the compression channel 42. At this time, the first motor 6 is started, and the first motor 6 drives the first rotating shaft 8 to rotate. The first rotating shaft 8 drives the upper stirring drum 9 and the lower stirring drum 10 to rotate at high speed on the rotating shaft 11.
