[0024] For example, Figs. 1-2The utility model discloses a film coating machine.
[0025] A film coating machine, comprising a rack 1, a feeding mechanism 2, a glue coating mechanism 3, a drying lamp 4 and a material collecting mechanism 5, the feeding mechanism 2, the glue coating mechanism 3, the drying lamp 4 and the material collecting mechanism 5 are sequentially arranged on the rack 1, a first guide roller 6 is arranged between the glue coating mechanism 3 and the drying lamp 4, a first driving roller 7 is arranged between the drying lamp 4 and the material collecting mechanism 5, the height of the first driving roller 7 is higher than that of the first guide roller 6, the feeding mechanism 2 sequentially comprises a feeding roller 8 and a feeding guide assembly 9 arranged on the rack 1, and the material collecting mechanism 5 comprises a material collecting guide assembly 10, a first deviation rectifying mechanism 11 and a material collecting roller 12 sequentially arranged on the rack 1.
[0026] The utility model discloses discard traditional solvent type glue coating process, be applicable to solventless type glue coating, solve VOCs emission problem fundamentally, meet the current strict environmental protection standard. Compared with traditional equipment, based on this, the utility model simplifies mechanical structure, reduces unnecessary component, thereby greatly reduces the initial investment cost of equipment, and simultaneously, its compact design makes the whole system occupies small, is very suitable for the enterprise use of limited site, can arrange more production line under the same area condition, improves the production capacity in unit area.
[0027] It can be understood that, in some embodiments, the glue coating mechanism 3 adopts an adjustable film passing gap glue coating mechanism to meet the coating needs of different film thicknesses, and the glue coating mechanism 3 can also add a heating module in the roller to realize uniform coating and prevent bubbles from being generated.
[0028] The film coating machine comprises a rack 1, a feeding mechanism 2, a glue coating mechanism 3, a drying lamp 4 and a material collecting mechanism 5, the feeding mechanism 2, the glue coating mechanism 3, the drying lamp 4 and the material collecting mechanism 5 are sequentially arranged on the rack 1, a first guide roller 6 is arranged between the glue coating mechanism 3 and the drying lamp 4, a first driving roller 7 is arranged between the drying lamp 4 and the material collecting mechanism 5, the height of the first driving roller 7 is higher than that of the first guide roller 6, the feeding mechanism 2 sequentially comprises a feeding roller 8 and a feeding guide assembly 9 arranged on the rack 1, and the material collecting mechanism 5 comprises a material collecting guide assembly 10, a first deviation rectifying mechanism 11 and a material collecting roller 12 sequentially arranged on the rack 1.
[0029] This embodiment describes a film coating machine. The feeding guide assembly 9 includes a second guide roller 14 and a third guide roller 15 sequentially arranged on the frame 1. A second correction mechanism 16 is provided between the second guide roller 14 and the third guide roller 15. The third guide roller 15 is located outside the coating mechanism 3. Specifically, the second correction mechanism 16 between the second guide roller 14 and the third guide roller 15 in the feeding guide assembly 9 effectively prevents the film from shifting or wrinkling before entering the coating area, ensuring the consistency and stability of the coating quality, thereby reducing the scrap rate and improving the final product qualification rate.
[0030] The film coating machine described in this embodiment includes a feeding guide assembly 9 comprising a fourth guide roller 17, a fifth guide roller 18, and a sixth guide roller 19 arranged sequentially. Specifically, adding more guide rollers (the fourth to sixth guide rollers) to the feeding guide assembly 9 further refines the control of the film path, enabling the film to pass smoothly through each processing stage, avoiding problems caused by uneven friction, and enhancing the reliability and adaptability of the production line.
[0031] This embodiment describes a film coating machine, in which the take-up guiding assembly 10 includes a seventh guide roller 20, an eighth guide roller 21, a ninth guide roller 22, a tenth guide roller 23, and an eleventh guide roller 24 sequentially arranged on a frame 1. The height of the eighth guide roller 21 and the tenth guide roller 23 is lower than the height of the seventh guide roller 20, the ninth guide roller 22, and the eleventh guide roller 24. Specifically, the specific height difference design in the take-up guiding assembly 10 increases the stroke within a limited space, effectively dissipating heat after curing. It also helps adjust the tension of the film during the winding process, ensuring neat and tight winding, reducing material waste, and facilitating subsequent processing.
[0032] In this embodiment of the film coating machine, the heights of the feeding roller 8 and the receiving roller 12 are both less than the heights of the coating mechanism 3 and the drying lamp 4. Specifically, the heights of the feeding roller 8 and the receiving roller 12 are designed to be lower than those of the coating mechanism 3 and the drying lamp 4. This layout helps to reduce the overall height of the equipment, lower the center of gravity, facilitate the feeding and receiving of materials, improve the safety and stability of the equipment during operation, and also facilitate daily maintenance and cleaning.
[0033] In this embodiment of the film coating machine, a third correction mechanism 25 is provided between the coating mechanism 3 and the drying lamp 4. Specifically, this mechanism can adjust the direction of the material after coating to ensure the drying and curing effect.
[0034] The thin film coating machine described in the embodiment adopts a UV lamp as the drying lamp 4. Compared with the traditional hot air method, the UV curing technology has the characteristics of rapid curing, and can complete the curing process of the glue in a very short time, greatly shortening the production cycle and improving the production efficiency. In addition, the heat generated by the UV lamp is small, which can effectively reduce energy consumption and meet the requirements of energy saving and emission reduction.
[0035] It can be understood that the first active roller 7, the feeding roller 8 and the receiving roller 12 in the application are connected to the output end of an external driving motor (not shown) to realize rotation in actual use.
[0036] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
