The toggle parts are used to toggle the plastic particles in the drying space 6. The rotation of the connecting shaft 21 drives the toggle parts on the rotating column 17 to rotate so that the plastic particles in the drying space 6 are evenly heated and dried.

[0098] Reference Figures 1 to 10 , the toggle portion comprises:

[0099] A fixing rod 25 is located in the rectangular groove 19 and is fixedly connected to the rotating column 17;

At the same time, the control device 2 is used to control the start of the opening and closing motor 42, so that the opening and closing shaft 43 fixedly connected to the output end of the opening and closing motor 42 rotates. Furthermore, the opening and closing plate 44 fixedly connected to the opening and closing shaft 43 rotates around the axis of the opening and closing shaft 43, thereby connecting the drying space 6 with the transmission space 7. The dried plastic particles enter the transmission space 7 through the material discharge groove 41 on the partition plate 5, and the plastic particles entering the transmission space 7 enter the plasticizing cylinder 46 through the discharge pipe 10.

[0129] The plasticizing mechanism is located below the drying cylinder 4 and is electrically connected to the control device 2 for plasticizing the dried plastic particles.

[0130] Refer to Figures 1 to 10 , the plasticizing mechanism includes:

[0131] The cushion block 45 is located below the drying cylinder 4.

[0132] The plasticizing cylinder 46 is arranged on the cushion block 45, and the discharge pipe 10 is communicated with the plasticizing cylinder 46.

[0133] The second motor 47 is arranged on the plasticizing cylinder 46 and is detachably and fixedly connected to the plasticizing cylinder 46. The second motor 47 is electrically connected to the control device 2.

[0134] The conveying shaft 48 is rotatably arranged on the plasticizing cylinder 46, and one end of the conveying shaft 48 close to the second motor 47 is fixedly connected to the output end of the second motor 47. The axis of the conveying shaft 48 coincides with the axis of the plasticizing cylinder 46.

[0135] There are multiple groups of spiral blades 49, and the spiral blades 49 are evenly arranged on the conveying shaft 48. The second motor 47 drives the conveying shaft 48 to rotate to drive the spiral blades 49 to rotate, and the spiral blades 49 rotate to convey the plastic particles in the plasticizing cylinder 46 out.

[0136] The heater 50 is arranged on the plasticizing cylinder 46 and is detachably and fixedly connected to the plasticizing cylinder 46. The heater 50 is electrically connected to the control device 2, and the heater 50 is used to heat and plasticize the plastic particles in the plasticizing cylinder 46.

[0137] After the plastic particles enter the plasticizing cylinder 46, the heater 50 is controlled to turn on by the control device 2, and then the second motor 47 is controlled to start, so that the conveying shaft 48 fixedly connected to the output end of the second motor 47 rotates, thereby causing the spiral blade 49 provided on the conveying shaft 48 to rotate around the axis of the conveying shaft 48. While plasticizing the plastic particles in the plasticizing cylinder 46 through the heater 50, the rotation of the spiral blade 49 realizes the plasticizing and conveying of the plastic particles that have been dried and entered the plasticizing cylinder 46, thereby improving the drying and plasticizing efficiency of the device for plastic particles to a certain extent.

[0138] Working principle: During operation, the staff opens the hopper lid 9, and then puts the plastic particles to be dried and plasticized into the drying space 6 of the drying cylinder 4 through the feed hopper 8. Then, the staff controls the dryer 23 to turn on through the control device 2, and then the staff controls the first motor 13 to turn on through the control device 2, so that the drive shaft 14 fixedly connected to the output end of the first motor 13 rotates, driving the connecting sleeve 15 fixedly connected to the drive shaft 14 to rotate. Through the cooperation between the fixing key 22 on the connecting shaft 21 and the key groove 16 on the connecting sleeve 15, the connecting shaft 21 rotates, causing the rotating column 17 fixedly connected to the connecting shaft 21 to rotate, thereby causing the fixing rod 25 provided in the rectangular groove 19 to rotate around the axis of the rotating column 17, so that the rotating ring 26 rotatably connected to the fixing rod 25 drives the connecting block 27 to rotate around the axis of the rotating column 17, and further causing the connecting block 27 to drive the connecting rod 28 to rotate around the axis of the rotating column 17, thereby causing the stirring blade 29 rotatably connected to the connecting rod 28 to rotate around the axis of the rotating column 17, so as to stir the plastic particles in the drying space 6, making the plastic particles in the drying space 6 in a moving state, thereby increasing the spacing between the plastic particles in the drying space 6 to a certain extent, which is beneficial to the evaporation of moisture on the plastic particles and the escape of moisture-containing air from between the plastic particles, and finally discharged through the exhaust holes 24 on the drying cylinder 4, thus completing the drying operation of the plastic particles in the drying space 6;

[0139] After the drying treatment of the plastic particles is completed, the control valve 11 is controlled to open by the control device 2, and at the same time, the opening and closing motor 42 is controlled to start by the control device 2, so that the opening and closing shaft 43 fixedly connected to the output end of the opening and closing motor 42 rotates, and then the opening and closing plate 44 fixedly connected to the opening and closing shaft 43 rotates around the axis of the opening and closing shaft 43, thereby connecting the drying space 6 with the transmission space 7. The dried plastic particles enter the transmission space 7 through the discharge groove 41 on the partition plate 5, and the plastic particles entering the transmission space 7 enter the plasticizing cylinder 46 through the discharge pipe 10;

[0140] After the plastic particles enter the plasticizing cylinder 46, the heater 50 is controlled to turn on by the control device 2, and then the second motor 47 is controlled to start, so that the conveying shaft 48 fixedly connected to the output end of the second motor 47 rotates, and thus the spiral blade 49 arranged on the conveying shaft 48 rotates around the axis of the conveying shaft 48. While the plastic particles in the plasticizing cylinder 46 are plasticized by the heater 50, the rotation of the spiral blade 49 realizes the plasticization and conveying of the plastic particles that have been dried and entered the plasticizing cylinder 46, thereby improving the drying and plasticizing efficiency of the plastic particles by this device to a certain extent.
