內(nèi)折返寬幅雙面擠壓式涂布機(jī)是一款高速高效率,高精度,高智能化的設(shè)備。主要由收放卷、機(jī)頭、牽引及烘箱等部分組成,其中涂布機(jī)頭和常規(guī)涂布機(jī)頭結(jié)構(gòu)一致,涂布精度和常規(guī)涂布機(jī)相同。而內(nèi)折返涂布機(jī)的核心部分烘箱采用特殊的內(nèi)繞式換向+閉環(huán)糾偏設(shè)計(jì),讓極片在同一節(jié)烘箱內(nèi)經(jīng)過(guò)兩次烘烤且運(yùn)行更加穩(wěn)定。
The inner fold-back wide-width double-sided extrusion coater is a high-speed, high-efficiency, high-precision, and highly intelligent device. It mainly consists of winding and unwinding, die head, traction, and drying oven. The coating die head has the same structure as a conventional coating die head, and the coating accuracy is the same as that of a conventional coating machine. The core component of the internal folding coating machine, the oven, employs a special internal winding reversing + closed-loop correction design. This allows the electrode sheets to undergo two baking cycles within the same oven section, resulting in more stable operation.
設(shè)備特點(diǎn)Equipment features
The oven length is halved, and the distance of the slurry conveying pipeline for the second coating head is simultaneously shortened, reducing the overall machine length by approximately 40%;
Overall energy consumption is reduced by 15-20%, and efficiency is doubled;
Unwinding is located on the slurry mixing side, and rewinding is located on the roller pressing side, facilitating material transfer;
There is no long-slope guide roller mechanism before entering the oven after the second coating, preventing electrode wrinkling;
When the electrode sheet reaches half its length within the oven, a closed-loop correction function at the folding point prevents deviation and wrinkling within the oven;
Each oven section is equipped with 11 active and passive guide rollers, eliminating roller rotation resistance and speed errors between rollers throughout the machine;
The electrode sheets inside the drying oven move in an S-shape, and there is no edge curling during drying; the electrode sheets move stably without shaking.
