Description

Technical Field

[0001] The invention belongs to the technical field of PI film production and transportation, and in particular relates to energy-saving transportation equipment for PI film production. Background Art

[0002] PI film is a type of thin-film insulating material made of pyromellitic dianhydride and diaminodiphenyl ether through polycondensation and cast film formation and then imidization. It is yellow and transparent, has good high and low temperature resistance, insulation, adhesion, and radiation resistance. It is widely used in aerospace, various electronic products, automobiles, and atomic energy industries.

[0003] The production and processing of PI film generally needs to go through the following steps: raw material preparation, batching, cast film, imidization, winding and testing. Among them, in the imidization process of PI film, the solid film needs to be transported to the imidization furnace and subjected to imidization reaction under high temperature conditions to complete the conversion from polyamic acid to polyimide.

[0004] PI film production and conveying equipment is a type of equipment that clamps solid films and feeds them into the imidization furnace. Currently, common PI film production and conveying equipment is mainly composed of clamping components, mobile conveying structures and control structures. When in use, the solid film to be conveyed is clamped by the clamping components, and the clamped solid film is moved and conveyed along with the movement of the mobile conveying structure.

[0005] Since PI film is a thin film material with a relatively soft texture, the PI film production and conveying equipment inevitably needs to clamp and convey the solid film during use. This makes the side edges of the solid film after imidization easily affected by the clamping components of the PI film production and conveying equipment and cause wrinkles. In order to subsequently, the deformed PI film sides need to be cut, which not only causes a waste of resources, but also increases the production cost of the PI film.

[0006] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0065] During specific use, the solid film to be cured is guided and conveyed by a pair of feed guide wheels 205, and the solid film to be cured is clamped by multiple assembly clamps 203. Subsequently, the conveyor chain 202 can be driven to move by controlling the rotation of the drive sprocket 204, so that the conveyor chain 202 can drive the clamping plate 203 to transport the solid film into the furnace body 1, and the solid film is subjected to imide curing treatment through the furnace body 1.

[0066] The solid film solidified by the furnace body 1 can be conveyed to the assembly frame 301 along the conveying guide wheel 306, and the single upper rotating shaft 302 can be driven to rotate by controlling the operation of the driving motor 308.

The solid film can be extruded, smoothed and frictionally conveyed through the reverse rotation of multiple groups of smoothing rollers 304. At the same time, the smoothing roller 304 can be heated by controlling the operation of the heating resistor wire 305, thereby improving the effect of extruding and smoothing the side of the solid film.

[0067] At the same time, the gas in the dust filter guide chamber 407 can be extracted and discharged by controlling the operation of the exhaust fan 409, and the discharged gas can be transported to the lower air distribution plate 411 and the upper air distribution plate 412 along the lower guide air duct 410 and the upper guide air duct 414.

The solid film can be cooled and solidified by blowing air toward the solid film after smoothing through another pair of lower air distribution plates 411 and the upper air distribution plates 412. The smoothed solid film can be rolled up under the guidance of the discharge guide wheel 309.

[0068] In addition, the exhaust fan 409 exhausts gas from the dust filter guide chamber 407 during operation. At this time, the gas in the assembly rack 301 can be transported along the gas collecting pipe 408 to the dust filter net cylinder 406, and the extracted gas is filtered through the dust filter net cylinder 406.
