According to a preferred embodiment of the invention, described preheat roll unit comprises preheat roll, described preheat roll center arranges swivel joint, described condensation water residual heat collecting pipe is contained on swivel joint, preheat roll arranges residual heat collection tube control flap and temperature indicator, utilizes condensation water residual heat to preheat film.

According to a preferred embodiment of the invention, described warm-up mill unit comprises warm-up mill, described warm-up mill center arranges swivel joint, described steam pipe is arranged on swivel joint, described warm-up mill arranges steam pipe by-pass valve control and temperature indicator, utilize the heat of steam to carry out post bake to film, ensure that film can soften further.

According to a preferred embodiment of the invention, establish many infrared heating pipe in infrared heating box unit, infrared heating box unit set temperature testing sensor carries out temperature control, after infrared heating pipe heating, when can ensure that film enters dandy roll, can reach soft state.

According to a preferred embodiment of the invention, embossing unit comprises the embossing steel rider and wool roller that cooperatively interact, and described embossing steel rider arranges embossing, utilizes embossing steel rod and wool roller to pressure, can ensure that embossing realizes convex-concave to pressure effect.

According to a preferred embodiment of the invention, the cold water pipeline that described chill roll unit comprises chill roll and matches with chill roll, to ensure that the film after embossing can cool in time, ensures embossing lines.

The online Embosser of a kind of mould release membrance coating machine of the present invention has the following advantages:

1, off-line embossing is after being coated with silicone oil and completing, and last volume forwards on embossing machine again, again embossing, and two procedures just can complete; An online but step completes and is coated with silicon and embossing, and joint eliminates one step from the process.

2, off-line embossing needs special two people to operate; Online embossing can utilize and be coated with silicon personnel, and two procedures unification procedure, per tour saves two operating personnel.

3, normal temperature film need be heated to softening point by off-line embossing again, and energy ezpenditure is large; Online embossing utilizes baking oven out self, with the film of higher temperature, and to utilize the exhaust-heat heating of steam condensate (SC), saves the energy.

4, off-line embossing the factor such as need to be heated again because of upper and lower volume and film, and speed of production is slow, and production efficiency is low, and timely delivery guaranteed rate is low; Online embossing be coated after, at once embossing, speed of production is fast, and production efficiency is high, and timely delivery guaranteed rate is high;

5, off-line embossing machine equipment investment is large, and maintenance cost is high; Online embossing investment is low, and maintenance cost is low.

6, to take production site large for off-line embossing machine; Online embossing machine occupied ground is little.
