Description

Technical Field

[0001] The utility model relates to the technical field of PI film manufacturing, and more specifically, to a PI film extrusion device. Background Art

[0002] PI film, also known as polyimide film, is the best performing thin-film insulating material in the world. It is made by polycondensing pyromellitic anhydride and diaminodiphenyl ether in a strong polar solvent and casting into a film, followed by imidization.

[0003] In the process of manufacturing PI film, an extrusion device is often used to extrude and mix the raw materials of the PI film. In actual use, although the existing extrusion device can realize the function of extrusion mixing, the feed port of the existing extrusion device generally does not have the function of controlling the amount of raw materials falling. If too much raw material is added, it is easy to cause the feed port to be blocked. At this time, it is necessary to manually dredge the feed port with the help of tools. This dredging method not only increases the workload of the operator, but also affects the production efficiency of the PI film, so it needs to be improved. Utility Model Content

[0025] A base 1, a cylinder 2 is fixedly connected to the top of the base 1, and a feed box 3 is fixedly connected to the top of the cylinder 2;

[0026] A quantity control mechanism, which is arranged on the top of the feed box 3;

[0028] When the driving motor 4 is running, the rotating shaft 5 will drive the rotating block 6 to rotate, and then the connecting rod 7 will rotate to pull the vertical rod 8 and the lifting block 9 to move upward, thereby achieving the purpose of controlling the amount of film raw materials falling.

[0029] Among them, a rotating motor 10 is fixedly connected to the right side of the top of the base 1, and a rotating shaft 11 is fixedly sleeved on the other end of the output shaft of the rotating motor 10. A spiral rod 12 is fixedly connected to the left side of the rotating shaft 11, and the left side of the spiral rod 12 penetrates the cylinder 2 and extends to the inside of the cylinder 2.

[0030] When the rotary motor 10 is running, the rotary shaft 11 will drive the screw rod 12 to rotate.

[0031] A circular hole 13 is formed on the top of the feed box 3 . There are two circular holes 13 , and the two circular holes 13 have the same size.

[0032] The design of the two circular holes 13 serves to place different film raw materials.

[0033] The top of the base 1 is fixedly connected to a pneumatic cylinder 14 located in front of the cylinder 2 , and the top of the pneumatic cylinder 14 is fixedly connected to a rectangular plate 15 .

[0034] When the pneumatic cylinder 14 is in operation, it will pull the rectangular plate 15 to move downward.

[0035] Among them, the left and right sides of the top of the rectangular plate 15 are hinged with a rotating rod 16, the other end of the rotating rod 16 is hinged with a connecting plate 17, the inner side of the connecting plate 17 is fixedly connected with a baffle 18, the number of the baffles 18 is two, the inner sides of the two baffles 18 both penetrate the top of the feed box 3 and extend to the inside of the feed box 3, and the two baffles 18 move towards each other to close the two circular holes 13.
