DETAILED DESCRIPTION

[0033] The production machine for producing thin films includes a feeding device and a processing device. The raw materials of the thin films need to be fed to the processing device through the feeding device. The raw materials are in liquid and solid forms, and the solid raw materials are in powder form. The feeding device of the existing thin film production machine has the following defects: since the liquid raw materials of the thin films are relatively viscous, the feeding speed is slow during feeding; since the powdered raw materials are easy to stick together during storage and transportation, they need to be manually broken up during feeding, resulting in low production efficiency.

[0034] To solve the above problems, the present application discloses a feeding device, including a liquid raw material conveying mechanism and a powdered raw material conveying mechanism opposite to the liquid raw material conveying mechanism, the liquid raw material conveying mechanism is used to deliver the liquid raw material of the film to the processing device of the film production machine, and the powdered raw material conveying mechanism is used to deliver the powdered raw material of the film to the processing device of the film production machine.

[0035] Please refer to Figure 2 The liquid raw material conveying mechanism includes a guide blade 15, a first conveying pipe 13 and a first driving member. The first driving member is transmission-connected to the guide blade 15. The guide blade 15 is rotatably arranged in the first conveying pipe 13. The liquid raw material is conveyed through the first conveying pipe 13. The guide blade 15 is rotated by the first driving member. The guide blade 15 in the rotating state has a guiding effect. The guide blade 15 accelerates the flow velocity of the liquid raw material in the first conveying pipe 13, thereby accelerating the feeding speed of the liquid raw material, and improving the defect of slow feeding speed due to the relatively viscous liquid raw material.

[0036] Please refer to Figure 2The powdered raw material conveying mechanism includes a crushing member 25, a second conveying pipe 24 and a second driving member 26. The second driving member 26 is transmission-connected to the crushing member 25. The crushing member 25 is arranged in the second conveying pipe 24. The powdered raw material is conveyed through the second conveying pipe 24. The crushing member 25 is rotated by the second driving member 26. The crushing member 25 in the rotating state can break up the bonded powdered raw materials, thereby increasing the mixing efficiency of the powdered raw materials and the liquid raw materials, eliminating the step of manually breaking up the bonded powdered raw materials when feeding, thereby improving production efficiency.

[0037] The feeding device of the present application is used to conveniently feed the raw materials of the film to the processing device of the film production machine, which is beneficial to speeding up the feeding speed and improving the production efficiency.

[0038] Polyimide film is a type of film, and is widely used. The production machine for producing polyimide film includes a feeding device and a processing device. The raw material of the polyimide film is fed to the processing device through the feeding device. The raw material is in liquid and solid form, and the solid raw material is in powder form. The feeding device of the existing polyimide film production machine has the following defects: since the liquid raw material of the polyimide film is relatively viscous, the feeding speed is slow during feeding; since the powdered raw material is easy to stick together during storage and transportation, it needs to be manually broken up during feeding, and the production efficiency is low. When the feeding device of the present application feeds the liquid raw material and powdered raw material of the polyimide film to the processing device of the film production machine, the above problems can be solved.

After the charging is completed, the connection between the cover plate 9 and the box body is restored and the first feed box 2 and the second feed box 22 are installed back on the frame.

[0042] Similarly, when cleaning the first feed box 2 and the second feed box 22, the first feed box 2 and the second feed box 22 are removed from the frame, and then the cover plate 9 is removed from the box body, and the cleaning operation is carried out smoothly. After the cleaning is completed, the connection between the cover plate 9 and the box body is restored and the first feed box 2 and the second feed box 22 are installed back on the frame.
