[0023] In order to more clearly understand the technical means of the present utility model and implement it according to the content of the specification, the following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but not to limit the scope of the present utility model.
[0024] See the attached Figures 1-5 As shown, the processing mechanism for increasing the adhesion of the coating surface on the film surface in the first embodiment includes: a frame 1 for being mounted on a coating machine; a double-sided non-contact dust removal device 6 near the discharge port of the frame 1; the frame 1 needs to be installed on a film coating machine so that the processed film can be guided and conveyed to the coating machine by guide rollers, and the processed film can pass through the double-sided non-contact dust removal device 6, so that it can perform double-sided dust removal on the film and improve the processing effect of the film.
[0025] A feeding mechanism provided on the frame 1 that can realize the input of the film, and this feeding mechanism can realize the adsorption and conveyance of the film at the entrance of the oven; the feeding mechanism includes: an adsorption roller 2, and a plurality of air holes are provided on the surface of the adsorption roller 2; a guide roller 21 that can freely adjust its height; a mounting seat 22 fixed on the frame 1 and located below the guide roller 21; and an adjusting cylinder 23 provided on the frame 1 for realizing the height adjustment of the guide roller 21, and the output end of the adjusting cylinder 23 is rotatably connected to the guide roller 21 through a bearing seat.
[0026] The film material can be conveyed by the rotation of the adsorption roller 2. When the film material is conveyed by the adsorption roller 2, the film material can be adsorbed by the suction of the air holes, so that the film material can closely adhere to its surface when passing through the adsorption roller 2, making the film material keep a tense effect during subsequent conveyance, avoiding affecting the subsequent coating. Moreover, during the conveyance of the film material, the height of the guiding roller 21 can be adjusted by adjusting the operation of the air cylinder 23, realizing the tension adjustment during the conveyance of the film material, and it can also be adjusted according to the thickness of the film material, improving the practicability.
[0027] One end of the adsorption roller 2 is connected with a gas delivery pipe 24, and the other end of the gas delivery pipe 24 is connected with an air pump 25. The adsorption roller 2 and the gas delivery pipe 24 are rotationally and sealingly connected.
[0028] When the air pump 25 is working, it can extract the air inside the adsorption roller 2 through the gas delivery pipe 24. Since the air inside the adsorption roller 2 is pumped away, negative pressure will be generated in the air holes on the surface of the adsorption roller 2, so that the film material can be adsorbed by using air pressure, and the dust on the film material can be sucked away by the adsorption method, achieving the preliminary treatment of the film material.
[0029] A guiding mechanism installed on the frame 1 for guiding the film material after dust blowing treatment; the guiding mechanism includes: a roller seat 3 fixedly installed on the frame 1; a guiding roller 31 rotatably connected with the roller seat 3.
[0030] Through the guiding mechanism, not only can the film material be guided, but also the film material can be kept in a tense state during conveyance and will not be loose. Since the guiding roller 31 is installed on the frame 1 through the roller seat 3, when the roller seat 3 adjusts the installation angle or position on the frame 1, the tension degree before the film material is conveyed can be manually adjusted.
[0031] And an adhesion treatment mechanism for increasing the adhesion of the coating surface of the film material. The adhesion treatment mechanism includes: a transition roller group for receiving and guiding the film material; a driving roller group for guiding the film material and increasing the conveying force. The transition roller group can guide and convey the film material to the driving roller group; a reverse roller 45 arranged on the frame 1 and close to the driving roller group, which is used to fit the film material conveyed by the driving roller group, and the reverse roller 45 increases the adhesion of the coating surface of the film material by reversing; an adjustment bracket 42 for adjusting the driving roller group to be close to or away from the reverse roller 45; and a discharging roller 46 arranged at the bottom of the frame 1.
[0032] The adjustment bracket 42 can adjust the position of the driving roller group, so that the distance can be adjusted according to the thickness of the film material.
[0033] The film material conveyed through the guiding mechanism can be connected by a transition roller group and then conveyed to the driving roller group. The driving roller group can increase the conveying force of the film material. When the driving roller group conveys the film material, the reverse roller 45 can rotate reversely on the attachment surface of the film material. Through the reverse rotation of the reverse roller 45 and the physical friction with the film surface, the adhesion force of the coating surface is increased. After the friction between the coating surface of the film material and the reverse roller 45, the film material can directly enter the coating equipment without contacting other guide rollers, and the adhesion force of the coating surface will not deteriorate. Using the reverse roller 45 to increase the adhesion force of the film surface has no waste liquid discharge and does not pollute the environment. This structure has a lower cost than a corona machine and does not generate ozone. The surface tension of the material after being treated by the reverse roller 45 will not decrease, which is of great significance for improving production efficiency and product quality.
[0034] Furthermore, a dust suction mechanism capable of performing dust suction treatment on the film material is also provided on the frame 1. The dust suction mechanism includes: a dust suction chamber 5 fixed on the frame 1; and a bag - type filter box 51 provided at the bottom of the dust suction chamber 5 and communicating with its interior.
[0035] Since the reverse roller 45 will friction with the film surface, it will adhere to the dust, lint, and fine impurities on the film surface. The adhered dust can enter the dust suction chamber 5 and finally be filtered by the bag - type filter box 51, which can prevent the dust from adhering to the film surface again and is convenient for the unified treatment of dust.
[0036] When the dust suction chamber 5 generates negative pressure suction, it can also directly extract the dust particles on the film surface and make them enter the interior of the dust suction chamber 5 to achieve the function of dust suction.
[0037] Furthermore, an arc - shaped dust inlet 53 is provided on the surface of the dust suction chamber 5. The dust inlet 53 is adaptively arranged with the reverse roller 45, and the dust inlet 53 facilitates the arrangement of the reverse roller 45 therein.
[0038] Furthermore, a pipeline connection port 52 is provided on one side of the bag - type filter box 51. The pipeline connection port 52 can be connected to a gas extraction device. When the gas extraction device works, it can extract the air inside the bag - type filter box 51. Since the bag - type filter box 51 communicates with the interior of the dust suction chamber 5, the air inside the dust suction chamber 5 can be extracted, thereby extracting and filtering the dust adhered by the reverse roller 45.
[0039] Furthermore, the transition roller group includes: a first transition roller 4 for secondary guiding of the film material guided by the guiding mechanism, and a second transition roller 41 for guiding the film material to the driving roller group in cooperation with the first transition roller 4.
[0040] Furthermore, the driving roller group includes: a first driving roller 43 and a second driving roller 44 arranged on the adjusting bracket 42 in sequence from top to bottom.
[0041] The arrangement from top to bottom can avoid the treated film surface from contacting the guide rollers and prevent the guide rollers from affecting the treated film surface.
[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and modifications can be made without departing from the technical principle of the present utility model, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
