Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a coating machine with an external main machine. Background Art

[0002] Coating machines are mainly used for surface coating production of films, papers, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and then dries it into a roll.

[0003] After the coating machine completes the gluing, in order to prevent the undried glue surface from sticking to the conveyor roller, the glue surface needs to face upward and the conveyor roller needs to support the bottom of the material and send the material into the oven for drying before it is rolled up. For example, the Chinese invention patent "A film coating machine" (Announcement No. CN203791126U, announcement date 2014.08.27) has the unwinding mechanism, traction mechanism, mesh roller coater, etc. built into the machine body, so that after the gluing is completed, it can be sent out from one end of the machine body and returned to the oven on the upper part of the machine body. At this time, the glue surface of the material faces upward, which can effectively avoid the sticking phenomenon. However, since this type of coating machine has the unwinding mechanism, traction mechanism, screen roller coater and other main machine parts built into the machine body, the whole machine body needs to be raised, which easily leads to the whole machine body being too high and the machine cannot be set up in a factory building with a generally low floor height, especially in an upper factory building, which generally has a floor height of no more than 5 meters for the sake of structural safety. In order to solve this problem, the utility model provides a coating machine with an external main machine, which can ensure that the adhesive surface of the material faces upward and can reduce the height of the machine body.

[0012] Furthermore, the winding unit also includes a rewinding and receiving unit, and a receiving reversing unit for guiding the substrate to the rewinding and receiving unit or the central winding unit is provided between the rewinding and receiving unit and the central winding unit.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: in the utility model, the unwinding unit, the gluing unit, the winding unit, etc. are all arranged outside the oven unit, so there is no need to raise the oven bracket, which is beneficial to reducing the overall height of the machine, making it more suitable for factories with lower heights.
