Description

Technical Field

[0001] The utility model relates to the technical field of corona treatment devices, in particular to a film uniform corona treatment device. Background Art

[0002] The corona treatment device is mainly used for the surface treatment of plastic film or plastic sheet products. Before the above materials are subjected to ink printing, lamination, film blowing, coating, bonding, material modification, grafting, polymerization, coating, casting, and pasting processing, in order to make the surface of the product have stronger adhesion (i.e., higher dyne coefficient) and prevent the raw materials from having printing color throwing, loose lamination and uneven coating during the production process, thus affecting the product quality, they must be corona treated first. The principle of corona treatment is to use high frequency and high voltage to generate corona discharge on the surface of the treated film to generate low-temperature plasma, so that the surface of the film produces free radical reaction and the polymer is cross-linked, the surface becomes rough and its wettability to polar solvents is increased.

[0003] The existing thin film corona treatment device has the following main disadvantages during use: since the thin film corona treatment is greatly affected by the air humidity, when the air humidity in the environment is high, the effect of the thin film corona treatment is significantly reduced. In addition, during the corona treatment, some ozone gases harmful to the human body will be generated. If these gases are not treated, they will cause certain damage to the human respiratory tract. Therefore, there is room for improvement. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0026] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Embodiment 1

[0027] Combination Figure 1-5 As shown, this embodiment provides a thin film uniform corona treatment device, including: a main body mechanism 100 and a treatment mechanism 200.

[0028] The main mechanism 100 includes a shell 110 , guide rollers 120 symmetrically mounted on the inner wall of the shell 110 , support rollers 130 rotatably mounted on the inner wall of the shell 110 , and a corona generator 140 mounted on the inner top wall of the shell 110 .

[0029] The shell 110 is used to install other components and form a sealed environment to separate the inner cavity of the shell 110 from the external environment to prevent changes in the humidity of the external environment from affecting the inner cavity of the shell 110. Through holes 111 are opened on both sides of the shell 110 for the film to enter the inner cavity of the shell 110.

[0030] The guide roller 120 is used to guide the film, the support roller 130 is used to unfold the film, and the corona generator 140 is used to perform corona treatment on the film.

[0031] The processing mechanism 200 is installed on the shell 110, including a tube body 210 installed on both sides of the shell 110 and connected to the inner cavity of the shell 110, a high-speed fan 220 installed on the inner wall of one side of the tube body 210, an electric heating wire 230 installed on the inner wall of one side of the tube body 210, and a placement frame 240 movably embedded in the tube bodies 210 on both sides and fixed to the tube bodies 210 by magnetic attraction.

[0032] The tube body 210 is connected to the inner cavity of the shell 110 and is used to install other components. A filter screen 212 is provided on the inner wall of the tube body 210 to prevent external dust and impurities from entering the inner cavity of the shell 110. The high-speed fan 220 is used to inhale external air and accelerate it into the inner cavity of the shell 110. The heating wire 230 is used to heat the air in the tube body 210 to evaporate the moisture in the air for subsequent processing.

[0033] The placement frame 240 is embedded in the tube body 210. One side of the placement frame 240 is filled with lime powder to absorb water molecules in the air, thereby ensuring the dryness of the air. The other side of the placement frame 240 is filled with activated carbon to absorb ozone gas in the air to prevent it from being discharged into the external environment and causing damage to the human respiratory tract.

[0034] In addition, the high-speed fan 220 , the heating wire 230 , and the placement frame 240 filled with lime powder are all located in the same side tube body 210 , thereby ensuring the drying effect of the air entering the inner cavity of the shell 110 .

[0035] The placement frame 240 includes a frame body 241 embedded in the inner cavity of the tube body 210, a plurality of mesh tubes 242 arranged in a circular array and passing through the frame body 241, and a cover plate 243 hingedly installed on the top of the frame body 241. The frame body 241 extends into the inner cavity of the tube body 210 for filling lime powder or activated carbon. The mesh tube 242 is arranged through the frame body 241 for air to pass through. The mesh tube 242 is provided with a plurality of micropores in a circular array, and the diameter of the micropores is 2 mm, which is convenient for the lime powder to absorb water vapor in the air or the activated carbon to absorb ozone gas in the air. The cover plate 243 is used to close the frame body 241.

[0036] Magnetic female buckles 211 are fixed on both sides of the tube body 210, and magnetic sub-buckles 2411 are fixed on both sides of the frame body 241. The magnetic sub-buckles 2411 and the magnetic female buckle 211 are mutually attracted to ensure the stability of the frame body 241 and facilitate the installation and disassembly of the frame body 241.

[0037] The working principle and use process of the utility model are as follows: when in use, the film is passed through the guide roller 120 on one side, bypasses the support roller 130, and passes through the guide roller 120 on the other side, and the corona generator 140 is started to perform corona treatment on the film. When the treatment is performed, the high-speed fan 220 is started to send the outside air into the inner cavity of the shell 110. When the air passes through the heating wire 230, it is heated by the heating wire 230 to evaporate the water molecules in the air, and then enters the placement frame 240 with lime powder. The lime powder adsorbs the water molecules in the air to form dry high-temperature air and send it into the shell 110 to ensure the dry environment in the shell 110. At the same time, the air with ozone gas generated during the treatment in the shell 110 is sent out through the tube body 210 on the other side. When passing through the placement frame 240 filled with activated carbon, the ozone gas in the air is adsorbed by the activated carbon to prevent it from being discharged into the external environment.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
