3) the fixed die roller rotates anticlockwise to flatten, average and control the thickness of the glue on the transfer roller; the fixed mold roller is attached to the transfer roller, a gap exists between the fixed mold roller and the transfer roller, and the transfer roller needs flattening control due to uneven thickness of glue caused by continuous rotation and accumulation;

4) the frame III is pushed to slide along the guide rail II by rotating the turbine propelling mechanism, and the distance between the mold adjusting roller and the transfer roller is adjusted; accurate displacement data are obtained through the incremental stay wire displacement sensor, so that the adjustment is more accurate;

5) carrying out glue scraping treatment on the fixed die roller through a glue scraping mechanism; glue on the fixed mold roller can be gradually accumulated and thickened, so that the glue is prevented from being stuck on the transfer roller again after rotating; the position and the height of the scraper can be adjusted by matching the rotating shaft with the connecting rod I and the connecting rod II so as to meet the glue scraping requirement of the fixed die roller;

firstly, taking out the insert block, pulling the adjusting sleeve to the clamping groove I, and then inserting the insert block into the fixed lug plate and the clamping groove I to enable the teeth of the clamping block to be disengaged from the meshing contact with the gear I; then the adjusting hand wheel is rotated to drive the rotating shaft to rotate to complete the adjustment of the scraping plate; finally, the adjusting sleeve is reset to the position of the clamping groove II and is fixed through the inserting block inserted into the fixed lug plate and the clamping groove II, and the clamping block is reset and fixedly locks the rotating shaft through the tooth meshing gear I;

6) the turbine propelling mechanism is rotated to push the rack II to slide along the guide rail I, and the distance between the transfer roller and the printing rubber roller is adjusted.

The utility model provides an aluminium of accurate control film thickness rolls up rubber coating mechanism, the working process as follows: firstly, picking up glue in a glue pool through a picking-up roller, then transferring the glue onto a transfer roller by the rotation of the picking-up roller, then controlling the thickness of glue on the transfer roller by the rotation of the transfer roller through the die setting of a die setting roller, and finally transferring the glue onto a glue printing roller through the transfer roller; the distance between the fixed die roller and the transfer roller is controlled by the turbine propelling mechanism, and the displacement value is measured and displayed by the incremental stay wire displacement sensor.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the present invention as defined in the accompanying claims.
