The coating head can use various coating methods, such as roller coating, blade coating, and spraying, to evenly apply the coating containing the barrier material to the surface of the high-barrier membrane. The coating supply device ensures a stable supply of coating and precise metering.

[0003] Chinese patent number CN220879442U discloses a packaging film coating device comprising a device housing, a coating chamber disposed within the housing, and a support platform disposed within the coating chamber. The packaging film coating device of the utility model utilizes a film coating mechanism, a transmission mechanism, and a hydraulic telescopic rod to drive the support platform to be raised and lowered according to the thickness of the packaging bag body. The distance between the coating roller and the packaging bag meets the coating requirements.

[0004] However, the liquid storage position in the equipment cannot be adjusted according to the surface width of the finished material. Due to the inflexible design of the coating device and the lack of an effective adjustment mechanism, the coating liquid may accumulate in unnecessary areas, resulting in liquid waste, which not only increases costs but may also cause equipment failure or damage.

[0005] To this end, a high-barrier film barrier layer coating device is proposed. Utility Model Content

[0028] Example 1

[0029] like Figures 1-5As shown, an embodiment of the present invention provides a high-barrier film barrier layer coating device, including a coating bin 1, the rear end of the coating bin 1 is fixedly connected to a drying bin 2, the rear end of the drying bin 2 is fixedly connected to a discharge bin 3, the rear end of the discharge bin 3 is provided with a discharge opening 4, the rear end of the discharge bin 3 and the front end of the coating bin 1 are both equipped with a winding roller 5, the lower inner wall of the coating bin 1 is fixedly connected to a power transmission belt 7, the upper inner wall of the coating bin 1 is equipped with a storage inner bin 8, the lower end opening of the storage inner bin 8 is fixedly connected to a discharge arc outer frame 15, the inner end of the winding roller 5 is rotatably connected to a coating roller 9, the front and rear inner walls of the storage inner bin 8 are symmetrically provided with inner groove strips 12, and the lower inner wall of the inner groove strip 12 is equipped with a plurality of electric rotating shafts 13, and the plurality of electric rotating shafts 13 are arranged equidistantly from left to right, and a flexible blocking block 14 is installed at the upper end of the electric rotating shaft 13.

[0030] The material film body 6 is wound between the two winding rollers 5, and the material film body 6 passes through the coating bin 1, the drying bin 2 and the discharge bin 3. The front and rear ends of the discharge arc outer frame 15 are symmetrically provided with material clamping grooves 16. The end of the flexible blocking block 14 away from the electric rotating shaft 13 is fixedly connected with a protruding blocking block 17, and the protruding blocking block 17 and the material clamping groove 16 are engaged with each other. The left and right ends of the flexible blocking block 14 are fixedly connected with side sealing strips 18, and the two adjacent side sealing strips 18 abut against each other. The inner end of the storage inner bin 8 is filled with a certain coating liquid, and a discharge gap is set between the coating roller 9 and the storage inner bin 8.

[0031] Example 2

[0032] like Figures 1-5 As shown, in one embodiment, a plurality of drying rollers 10 are rotatably connected to the lower sides of the left and right inner walls of the drying chamber 2, and the plurality of drying rollers 10 are equidistantly arranged from front to back. The material film body 6 is located above the drying rollers 10, and the outer ends of the drying rollers 10 are fixedly connected to a heat-conducting surface layer 11, and the heat-conducting surface layer 11 is in contact with the material film body 6.

[0033] After the coating operation is completed, the material film body 6 can pass through the drying chamber 2, and the drying airflow in the drying chamber 2 can be used to assist in drying the material film body 6 above the drying roller 10, and a heat-conducting surface layer 11 is provided on the outside of the drying roller 10.
