[0002] The degradable active packaging film is a packaging film that can be decomposed into harmless substances in the natural environment. The main feature of the packaging film is its biodegradability, which can be gradually decomposed into water, carbon dioxide and other natural substances under the action of microorganisms. However, when producing the packaging film, the raw materials need to be mixed and added to the extruder for production, so an extruder is required.
[0003] At present, most extruders add raw materials into a sand hourglass, and the raw materials enter the extruder by their own gravity. During the production process, the raw materials in the feeding sand hourglass will gradually decrease, and the amount of raw materials entering the extruder will also slowly decrease, resulting in inconsistent parameters such as the size and density of the extruded packaging film, affecting the quality of the packaging film and thus being inconvenient to use.

Specific implementation mode
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] The present invention provides a technical solution: As Figure 1 - Figure 5 shown, in this embodiment, an extruder for preparing a degradable active packaging film includes a workbench 1. A driving device 3 is fixedly installed on one side of the upper end of the workbench 1. A transmission device 4 is arranged on one side of the driving device 3. The output end of the driving device 3 is in transmission connection with the input end of the transmission device 4. The output end of the transmission device 4 is in transmission connection with a transmission rod 6. A storage barrel 5 is fixedly connected to the other side of the upper end of the workbench 1. One side of the upper end of the storage barrel 5 is fixedly communicated with a feeding pipe 8. The middle of the upper end of the storage barrel 5 is fixedly connected with a protection box 7. One side of the inner wall of the protection box 7 is rotatably connected with a bevel gear one 18. One side of the bevel gear one 18 is fixedly connected with one end of the transmission rod 6. One side of the bevel gear one 18 is engaged with a bevel gear two 19. One side of the bevel gear two 19 is fixedly connected with a rotating shaft 20. One end of the rotating shaft 20 is fixedly connected with a stirring frame one 14. One end of the stirring frame one 14 is fixedly connected with a discharging blade 16. The outer side wall of the discharging blade 16 is attached to the discharging end of the storage barrel 5. By adding the raw materials for producing the packaging film into the storage barrel 5, when the driving device 3 is started, the transmission device 4 and the extrusion blade 13 rotate simultaneously. With the cooperation of the bevel gear one 18 and the bevel gear two 19, the stirring frame one 14 and the discharging blade 16 rotate simultaneously in the storage barrel 5. The raw materials of the packaging film enter the extrusion barrel 2 evenly through the threads of the discharging blade 16, ensuring that the amount of raw materials entering the extrusion barrel 2 is the same and improving the quality of the packaging film produced by the equipment.
[0022] As Figure 2 - Figure 5As shown, on the other side of bevel gear 18, there is a meshing bevel gear 21. At the lower end of bevel gear 21, there is a fixedly connected stirring frame 15. The inner wall of stirring frame 15 is rotationally connected to the outer wall of the rotating shaft 20 at one side. By driving bevel gear 18 to rotate through the transmission device 4, bevel gear 19 rotates in the opposite direction to bevel gear 18, causing stirring frame 14 and stirring frame 15 to rotate in opposite directions inside the storage cylinder 5, achieving full stirring of the raw materials in the storage cylinder 5 and preventing uneven mixing of the raw materials for producing the packaging film, which may affect the quality of the packaging film.
[0023] As Figure 2 and Figure 3 shown, on one side of the inner wall of the storage cylinder 5, there is a fixedly connected support frame 17. The inner wall of the support frame 17 is rotationally connected to the outer wall of the stirring frame 14 at one side. Through the structural design of the support frame 17, it is possible to prevent the stirring frame 14 and the stirring frame 15 from shaking inside the storage cylinder 5, which may affect the stirring.
[0024] As Figure 1 and Figure 2 shown, at the lower end of the storage cylinder 5, there is a through - connection with an extrusion cylinder 2. Inside the extrusion cylinder 2, there is a rotationally connected extrusion blade 13. One end of the extrusion blade 13 is fixedly connected to the input end of the transmission device 4. The raw materials are extruded through the extrusion blade 13 to produce the packaging film.
[0025] As Figure 1 and Figure 2 shown, on one side of the outer wall of the extrusion cylinder 2, there is a clamped extrusion head 9. On the outer wall of the extrusion head 9, there is a threaded connection with a fixing bolt 10. One end of the fixing bolt 10 is threadedly connected to the outer wall of the extrusion cylinder 2 at one side. Through the structural design of the fixing bolt 10, the extrusion head 9 can be replaced, improving the versatility of the equipment.
[0026] As Figure 1 and Figure 2 shown, on the other side of the outer wall of the extrusion cylinder 2, there is a support seat 12. The lower end of the support seat 12 is fixedly connected to the upper end of the workbench 1. The upper end of the support seat 12 is fixedly connected to an installation frame 11. Through the support seat 12 and the installation frame 11, it is ensured that the extrusion blade 13 will not shake during operation.
[0027] The present utility model provides an extruder for preparing a degradable active packaging film. The specific working principle is as follows:
[0028] When producing the degradable active packaging film, first add the proportioned raw materials into the storage cylinder 5 through the feeding pipe 8, and then start the driving device 3 to make the transmission device 4 and the extrusion blade 13 rotate simultaneously. When the transmission device 4 drives the first bevel gear 18 to rotate, the rotation direction of the second bevel gear 19 is opposite to that of the first bevel gear 18, so that the first stirring frame 14 and the second stirring frame 15 rotate in opposite directions in the storage cylinder 5, realizing full stirring of the raw materials in the storage cylinder 5. The raw materials of the packaging film after stirring enter the extrusion cylinder 2 evenly through the threads of the discharge blade 16. The cooperation of the extrusion blade 13 and the extrusion head 9 produces the packaging film. When producing packaging films of different thicknesses, the staff can replace the extrusion head 9 by loosening the fixing bolts 10.
[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
