Reversely-rotating trowelling roller for coated battery diaphragm output of drying oven

Abstract

The invention discloses a reversely-rotating trowelling roller for a coated battery diaphragm output of a drying oven. The reversely-rotating trowelling roller comprises the drying oven, a coating mechanism arranged on the front side of the drying oven, a reverse trowelling mechanism installed on the back side of the drying oven and a take-up mechanism arranged on the back side of the reverse trowelling mechanism. A transmission belt is installed in the drying oven. A film is placed on the transmission belt. The reverse trowelling mechanism sequentially comprises a stainless steel roller guide roller, a first stainless steel guide roller group, a ceramic trowelling roller, a second stainless steel guide roller group and a rubber compression roller from front to back. According to the reversely-rotating trowelling roller for the coated battery diaphragm output of the drying oven, the ceramic trowelling roller is driven to rotate through a motor, the rotating direction of the ceramic trowelling roller is opposite to the motion direction of the film, a coating with undried glue is trowelled by utilizing rolling friction produced through relative motion, the film is not damaged, and the uniformity of the coating coated on the film can be ensured.

Description

technical field [0001] The invention relates to a reverse direction smoothing roller, in particular to a reverse direction smoothing roller after the battery diaphragm is coated out of a drying box.

[0002] Cylindrical lithium-ion batteries are divided into different systems of lithium iron phosphate, lithium cobaltate, lithium manganate, cobalt-manganese mixed, and ternary materials. The shell is divided into two types: steel shell and polymer. Batteries with different material systems have different advantages; existing The technology is mainly based on steel shell cylindrical lithium iron phosphate battery. The performance of iron lithium battery is high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, high current discharge, electrochemical stability, and safety in use. , will not cause combustion or explosion due to improper operation such as overcharging, overdischarging, and short circuit, and has a wide operating temperature range and is environmentally friendly; it is widely used in solar lamps, lawn lamps, backup energy, power tools, and toy models; for cylinders type lithium battery, the quality of the positive and negative electrodes directly affects the quality of the battery; the existing production process of the positive and negative electrodes is as follows: first, the electrodes are coated, and then enter the oven after being coated by a coating roller, and the coated film is coated The layer is not uniform and smooth, but uneven, and it is necessary to roll the film coating. However, in the prior art, when the film coating is rolled, it is easy to cause incomplete rolling, or even due to excessive rolling. damage the film surface
