DETAILED DESCRIPTION

[0028] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp. Example

[0029] An extruder material preheating system, such as Figure 1 , Figure 2 , Figure 3As shown, it includes a preheating cylinder 1, which is arranged above the extruder. A feeding port 2 is provided on the top of the preheating cylinder 1, and a discharge port 3 is provided on the bottom. The discharge port 3 is connected to the feed port of the extruder. A heating component 4 and a transportation component 5 are provided in the preheating cylinder 1. The heating component 4 includes a heating disk 6, which is arranged between the feeding port 2 and the discharge port 3. The transportation component 5 drives the raw material to pass through the heating disk 6 and enter the discharge port 3. When the transportation component 5 drives the raw material to move, the heating disk 6 heats up along the moving trajectory, thereby preventing the heat-sensitive raw material from directly contacting the heating disk 6 with a higher temperature, which causes thermal decomposition and oxidation of the raw material.

[0030] The heating plate 6 includes a heat-conducting frame 7 and an electromagnetic coil 8. The electromagnetic coil 8 is arranged at the bottom of the heat-conducting frame 7. When the electromagnetic coil is energized, the heat-conducting frame 7 generates heat through resistance, thereby reducing the preheating time and increasing the heating efficiency of the equipment.

[0031] The transport assembly 5 includes a driving source 9, a driving shaft 10 and a transport tray 11. The driving source 9 includes a servo motor. A material drop hole 12 is provided in the middle of the transport tray 11. A connecting rod 13 is provided between the driving shaft 10 and the inner wall of the material drop hole 12. The heating tray 6 is provided at the bottom of the transport tray 11. When the driving source 9 drives the driving shaft 10 to rotate, the transport tray 11 is rotated and arranged on the heat-conducting frame 7. The temperature of each area of ​​the heat-conducting frame 7 is controlled by the number of turns of the electromagnetic coil 8, so that the effect of gradually heating up the heat-conducting frame 7 can be achieved. The inner wall of the preheating cylinder 1 is also provided with a There is a block 14, on which a guiding slope 25 is provided. A slot for the transport tray 11 to move is formed between the block 14 and the heat-conducting frame 7. The drop port 2 is arranged above one side of the block 14. When the raw material falls, it falls on the transport tray 11, which rotates and gradually heats up. A cold runner is arranged inside the block 14. When the transport tray passes under the block 14, the temperature is reduced, thereby preventing the transport tray from maintaining a high temperature and affecting the effect. When the material rotates to the block 14, the block 14 is used to resist the raw material and make it fall from the drop hole 12.

[0032] A conical surface 15 is also provided at the bottom of the preheating cylinder 1, and a heating plate 6 is fixedly provided on the surface of the conical surface 15. A stirring blade 16 is also provided at the bottom of the driving shaft 10, and a conical surface 17 is provided on the top side of the stirring blade 16. The raw materials are guided to the conical surface 15 through the conical surface 17, and the heating plate 6 is provided on the surface of the conical surface 15, so that the raw materials accumulated at the bottom of the preheating cylinder 1 are kept warm, and the raw materials are heated evenly by the stirring blades 16. An exhaust pipe 18 is also provided at the top of the preheating cylinder 1, and the exhaust gas of the product when the raw materials are heated is discharged through the exhaust pipe 18, so as to facilitate its recycling. Example

[0033] The difference between the second embodiment and the first embodiment is that Figure 4 , Figure 5 , Figure 6As shown, the transport component 5 includes a driving source 9, a driving shaft 10, a transport tray 19, a transport tray 20 and a transport tray 3 21, wherein a material drop hole 122, a material drop hole 23 and a material drop hole 3 24 are respectively provided in the middle of the transport tray 19, the transport tray 20 and the transport tray 3 21, a connecting rod 13 is provided between the driving shaft 10 and the transport tray 19, the transport tray 20 and the transport tray 3 21, three stoppers 14 are provided on the inner wall of the preheating cylinder 1, and guide slopes 25 are provided on the side ends of the three stoppers 14, which respectively correspond to the transport tray 19, the transport tray 20 and the transport tray 3 21, and a heating tray 6 is provided at the bottom of the transport tray 19, the transport tray 20 and the transport tray 3 21. A loading area 26 is provided on the material transport tray 19, the material transport tray 20 and the material transport tray 3 21. The loading area 26 of the material transport tray 20 corresponds to the material drop position of the material drop hole 1 22, and the loading area 26 of the material transport tray 3 21 corresponds to the material drop position of the material drop hole 23. After the material rotates one circle on the material transport tray 19, it resists the stopper 14 and falls from the material drop hole 1 22 and falls on the loading area 26 of the material transport tray 20. The material transport tray 20 drives the raw material to rotate one circle and then enters the loading area 26 of the material transport tray 3 21, thereby realizing gradual heating. By setting three material transport trays 11, the feed amount and feed speed of the equipment are increased, and the heating and insulation time is increased at the same time, which further increases the preheating effect.
