Heating roller heat-setting treatment device

Abstract

The invention provides a heating roller heat-setting treatment device. The heating roller heat-setting treatment device comprises heating roller heat-setting treatment parts of a certain quantity, wherein each group of the heating roller heat-setting treatment parts comprises two heating rollers which are arranged from top to bottom, the sizes and the shapes of the two heating rollers are same; each heating roller consists of a heat exchange tube, bearings and a heating roller shell; the heat exchange tube is fixedly disposed in the heating roller shell, and the bearings are respectively arranged at two sides of the heating roller shell and are connected with the heating roller shell in a shaft driving way. With the adoption of the heating roller heat setting treatment device, the problem that a diaphragm shakes in the diaphragm take-up operation process is effectively solved, good heat setting effect of the diaphragm is ensured, the pertinence is strong because the diameter of each heating roller can be designed according to actual production speed, the operation is relatively practical, and the heating roller heat setting treatment device is suitable for the needs of large-scale industrial production.

Description

Technical field [0001] The invention relates to the field of battery isolation film manufacturing, in particular to a heating roller heat setting processing device. Background technique [0002] Lithium-ion battery separator materials are currently a hot spot in the field of development and research in the field of new energy. Because the voltage and safety characteristics of the lithium battery system are very demanding, only a few major international companies in the United States and Japan can provide more suitable separator materials. It can be used in the field of low energy density lithium batteries. The production of diaphragm materials for lithium batteries generally includes two processes: diaphragm stretching and diaphragm modification. The diaphragm modification is mainly achieved by coating the diaphragm surface or chemical treatment. At present, there are many application researches on membrane modification at home and abroad, but they are mainly concentrated in the...

Problems solved by technology

[0004] The traditional separator coating machine often enters the winding operation directly through the traction device after passing through the coating unit and the drying unit. However, some current separator surface treatment processes often require the separator to be heat-set after coating before it can be finalized. Winding operation, but most of the current coating machines do not have this function. Even if they have this function, they usually adopt the same traditional blowing bellows structure as the drying box. Increased diaphragm jitter makes the diaphragm winding operation more difficult and reduces diaphragm production speed to some extent and increases the complexity of traction control
