Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure roller technology, and in particular to an anti-sticking pressure roller for a photovoltaic film applicator. Background Technology
[0002] In the photovoltaic field, to improve the utilization rate of sunlight, reflective films can be added to solar cells to increase the amount of sunlight reflected to the surface of the solar cells. During the process of attaching the reflective film to the surface of the object using a laminating machine, the reflective film needs to be heated and rolled. Because the reflective film becomes more viscous after hot pressing, it is prone to sticking to the surface of the pressure rollers during the rolling process. This causes deformation of the reflective film, affecting the solar cell manufacturing process. Furthermore, after repeated adhesion, the surface of the pressure rollers is prone to wear, and the anti-stick coating is consumed, thus affecting the rolling capacity of the pressure rollers and reducing their anti-stick effect. Utility Model Content
[0003] In view of this, the present invention provides an anti-sticking pressure roller for a photovoltaic film applicator.
[0004] To achieve the above objectives, according to one aspect of the present invention, an anti-sticking roller for a photovoltaic film applicator is provided, comprising:
[0005] Wheel hub;
[0006] The pressure roller body is fitted onto the aforementioned hub;
[0007] The aforementioned pressure roller body is provided with an isolation layer and an anti-sticking layer stacked from the inside out;
[0008] A number of adsorption pores penetrate radially through the above-mentioned pressure roller body and the above-mentioned hub;
[0009] A plurality of air vents penetrate radially through the aforementioned pressure roller body, the aforementioned hub, the aforementioned isolation layer, and the aforementioned anti-sticking layer.
[0010] Optionally, the aforementioned isolation layer is an anti-stick coating;
[0011] The aforementioned anti-stick coating includes a Teflon coating or a ceramic coating.
[0012] Optionally, the aforementioned anti-stick coating is applied to the side of the anti-stick layer facing the main body of the pressure roller;
[0013] or,
[0014] The aforementioned anti-stick coating is applied to the side of the pressure roller body facing the aforementioned anti-stick coating.
[0015] Optionally, when the anti-stick coating is applied to the side of the pressure roller body facing the anti-stick layer, a plurality of the adsorption pores also penetrate the anti-stick coating.
[0016] Optionally, the aforementioned isolation layer is a wrapping layer formed by a non-stick material film cloth that wraps around the main body of the pressure roller.
[0017] Optionally, the aforementioned wrapping layer includes a Teflon cloth layer.
[0018] Optionally, the aforementioned anti-stick layer includes Teflon tape or rubber granule tape.
[0019] Optionally, the main body of the pressure roller is made of hard metal material or high-temperature resistant soft material.

[0022] Optionally, in the circumferential direction of the pressure roller body, the adsorption pores and the blowing pores are arranged alternately.
[0023] One embodiment of the above-mentioned utility model has the following advantages or beneficial effects: By layering an isolation layer and an anti-sticking layer from the inside to the outside on the pressure roller body, and by using air vents that penetrate the pressure roller body, hub, isolation layer, and anti-sticking layer, the reflective film can be effectively prevented from sticking to the anti-sticking pressure roller during operation, thus avoiding deformation of the reflective film. The air pressure applied to the reflective film through the air vents makes the reflective film adhere more tightly to the surface of the object to be coated. The adsorption vents penetrating the pressure roller body and hub for adsorbing the isolation layer prevent the isolation layer from moving relative to the pressure roller body, further preventing movement of the reflective film during the coating process. Simultaneously, the combination of the adsorption vents and the isolation layer allows for convenient and quick replacement of the anti-sticking layer, facilitating the maintenance of the anti-sticking pressure roller.
[0024] The further effects of the aforementioned unconventional alternative methods will be explained below in conjunction with specific implementation methods. Attached Figure Description

[0031] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0032] It should be noted that, where there is no conflict, the embodiments of this utility model and the technical features thereof can be combined with each other.
[0033] Figure 1 This is a front view of the anti-sticking roller of the photovoltaic film applicator according to an embodiment of the present utility model; Figure 2 This is a cross-sectional schematic diagram of the anti-sticking roller of the photovoltaic film applicator according to the first embodiment of the present utility model; Figure 3 This is a cross-sectional schematic diagram of the anti-sticking roller of the photovoltaic film applicator according to the second embodiment of this utility model. Figure 1 , Figure 2 and Figure 3 As shown, the anti-sticking pressure roller of the photovoltaic film applicator according to this utility model embodiment includes: a hub 1; a pressure roller body 2 sleeved on the hub 1; an isolation layer 3 and an anti-sticking layer 4 stacked from the inside to the outside on the pressure roller body 2; a plurality of adsorption air holes 5 penetrating the pressure roller body 2 and the hub 1 in the radial direction; and a plurality of blowing air holes 6 penetrating the pressure roller body 2, the hub 1, the isolation layer 3 and the anti-sticking layer 4 in the radial direction.
[0034] The hub 1, serving as the main body of the anti-sticking roller of the photovoltaic film applicator, supports the overall structure and connects the roller body 2 to a shaft (not shown). Driven by the shaft, the hub 1 rotates the roller body 2, the outer isolation layer 3, and the anti-sticking layer 4. The hub 1 can be made of a material with sufficient strength and rigidity to support the weight of the roller body 2, the isolation layer 3, and the anti-sticking layer 4, and to withstand various forces generated during operation.
[0035] It is understood that the hub 1 can be connected to the pressure roller body 2 and the shaft in any way. As an example, the hub 1 can be fixedly connected to the pressure roller body 2, or the hub 1 can be connected to the shaft via a bearing.
[0036] The pressure roller body 2 can be made of rigid metal or high-temperature resistant soft material. When the pressure roller body 2 is made of rigid metal, it can provide a certain pressure to the reflective film during operation, ensuring that the attached reflective film has good surface flatness. As an example, the pressure roller body 2 can be made of rigid metal materials such as iron, steel, and aluminum alloy, but is not limited to these.
[0037] When the pressure roller body 2 is made of a high-temperature resistant soft material, it can avoid the problem of excessive pressure exerted on the reflective film during the reflective film application process, which could lead to stretching and deformation of the reflective film, thus effectively improving the yield rate of the reflective film application process. As an example, the pressure roller body 2 can be made of high-temperature resistant soft materials such as rubber or silicone, but it is not limited to these.
[0038] The isolation layer 3 is used to isolate the anti-stick layer 4 from the pressure roller body 2, and has a certain anti-stick effect. It can avoid the problem of the anti-stick layer 4 being difficult to replace due to direct contact between it and the pressure roller body 2. The isolation layer 3 can be an anti-stick coating or a wrapping layer.
[0039] When the isolation layer 3 is an anti-stick coating, the anti-stick coating may include a Teflon coating or a ceramic coating. The anti-stick coating may be applied to the side of the anti-stick layer 4 facing the pressure roller body 2, thereby isolating the anti-stick layer 4 from the pressure roller body 2. Alternatively, the anti-stick coating may also be applied to the side of the pressure roller body 2 facing the anti-stick layer 4.
[0040] When the isolation layer 3 is a wrapping layer formed by a non-stick material film covering the aforementioned pressure roller body 2, the wrapping layer may include one or more non-stick material films. As an example, the wrapping layer may be a single Teflon cloth layer or a single silicone cloth layer, or it may be a composite film layer composed of a combination of Teflon cloth and silicone cloth.
[0041] An anti-stick layer 4 is stacked on the outside of the isolation layer 3, providing a certain anti-sticking effect to prevent the reflective film from sticking to the anti-stick roller during operation. The anti-stick layer 4 may include Teflon tape or rubber granule tape, with the adhesive side facing the isolation layer 3. The anti-stick layer 4 prevents the reflective film from sticking to the anti-stick roller, further reducing the possibility of deformation during the application of the reflective film.
[0042] Several adsorption holes 5 are provided in the radial direction of the anti-sticking roller, penetrating the roller body 2 and the hub 1.
[0043] Specifically, when the isolation layer 3 is a wrapping layer, the anti-stick layer 4 is attached to the outside of the isolation layer 3. When the adsorption vent 5 draws air, it can tightly adsorb the isolation layer 3 and the anti-stick layer 4 onto the surface of the pressure roller body 2, preventing the isolation layer 3 and the anti-stick layer 4 from moving or falling off. This effectively prevents the reflective film from moving during the operation of the anti-stick pressure roller. In addition, when the adsorption vent 5 stops drawing air, the isolation layer 3 with the anti-stick layer 4 attached can be easily removed from the surface of the pressure roller body 2, facilitating the replacement of the isolation layer 3 and the anti-stick layer 4.
[0044] When the isolation layer 3 is an anti-stick coating, and the anti-stick coating is applied to the pressure roller body 2, as follows: Figure 3 As shown, the adsorption pores 5 penetrate not only the pressure roller body 2 and the hub 1, but also the anti-stick coating. When the adsorption pores 5 draw in air, they can tightly adhere the anti-stick layer 4 to the surface of the pressure roller body 2 coated with the anti-stick coating, preventing the anti-stick layer 4 from falling off during operation. When the adsorption pores 5 stop drawing in air, the anti-stick coating separates the pressure roller body 2 and the anti-stick layer 4, allowing the anti-stick layer 4 to be easily removed from the surface of the pressure roller body 2, facilitating its replacement. When the anti-stick coating is applied to the anti-stick layer 4, as... Figure 2 As shown, the adsorption pore 5 penetrates the pressure roller body 2 and the hub 1. When the adsorption pore 5 draws in air, it can tightly adsorb the anti-stick layer 4 coated with the anti-stick coating onto the surface of the pressure roller body 2, preventing the anti-stick layer 4 coated with the anti-stick coating from falling off when the anti-stick pressure roller is working. When the adsorption pore 5 stops drawing in air, since the anti-stick coating separates the pressure roller body 2 and the anti-stick layer 4, the anti-stick layer 4 coated with the anti-stick coating can be easily removed from the surface of the pressure roller body 2. A new anti-stick layer 4 coated with the anti-stick coating is used to wrap the pressure roller body 2, with the side coated with the anti-stick coating facing the pressure roller body 2, in order to replace the anti-stick layer 4 coated with the anti-stick coating.
[0045] It is understandable that, regardless of whether the anti-stick coating is applied to the surface of the pressure roller body 2 or the surface of the anti-stick layer 4, the anti-stick layer 4 can be tightly adsorbed onto the surface of the pressure roller body 2 by absorbing air through the adsorption pores 5, making the anti-stick layer 4 less likely to fall off. Furthermore, the anti-stick coating reduces friction and extends the service life of the anti-stick layer 4.
[0046] A plurality of air-blowing holes 6 are provided radially along the anti-sticking pressure roller, penetrating the pressure roller body 2, the hub 1, the isolation layer 3, and the anti-sticking layer 4. During the operation of the anti-sticking pressure roller, air is blown outward through the air-blowing holes 6 to prevent the reflective film from sticking to the anti-sticking layer 4. By blowing air onto the reflective film, the reflective film can be pressed firmly against the surface of the object to be coated, so that the reflective film can be more firmly attached to the surface of the object to be coated, thereby further improving the yield of the reflective film coating process.
[0047] It is understandable that in the anti-stick roller, provided that the blowing holes 6 and the adsorption holes 5 achieve the above-mentioned effects, the blowing holes 6 and the adsorption holes 5 can be arranged in any manner, and their size and spacing can be set according to actual conditions, without specific limitations here. For example, such as... Figure 2 As shown, the adsorption holes 5 and the blowing holes 6 are arranged alternately in the circumferential direction of the pressure roller body 2. As another example, two rows of holes are provided in the circumferential direction of the pressure roller body 2, one row being adsorption holes 5 and the other row being blowing holes 6.
[0048] It should be noted that, Figure 2 and Figure 3 The arrangement of the adsorption pores 5 and the blowing pores 6 is shown only as an example, and the arrangement of the adsorption pores 5 and the blowing pores 6 in this embodiment of the present invention is not limited to this.
[0049] In addition, the hub 1 can be configured as a hollow structure. Specifically, the hub 1 can be provided with an air intake pipe connected to the adsorption air hole 5 and an air blowing pipe connected to the air blowing hole 6, so as to control the adsorption air hole 5 to take in and stop taking in air through the air intake pipe, and to control the air blowing hole 6 to blow in and stop blowing air through the air blowing pipe.
[0050] The working principle of the anti-sticking pressure roller of the photovoltaic film applicator in this embodiment is as follows: During operation, air is drawn in through the suction pipe controlled by the suction port 5, firmly adhering the anti-sticking layer 4 to the surface of the pressure roller body 2, preventing the anti-sticking layer 4 from moving relative to the pressure roller body 2, and further preventing the reflective film from moving. Air is blown in through the blowing pipe controlled by the blowing port 6, and with the anti-sticking effect of the anti-sticking layer 4, the reflective film can be effectively prevented from sticking to the anti-sticking layer 4. During the replacement of the anti-sticking layer 4, the suction pipe is controlled by the suction port 5 to stop drawing air, so that the anti-sticking layer 4 can be easily removed from the surface of the pressure roller body 2. The blowing port 6 of the new anti-sticking layer 4 is aligned with the blowing port 6 on the surface of the pressure roller body 2 and then wrapped around the pressure roller body 2, and the replacement is completed.
[0051] It is understood that the anti-sticking roller of this utility model embodiment can be applied not only to photovoltaic film application machines, but also to other machines equipped with rollers. Therefore, the film applied using the anti-sticking roller of this utility model embodiment is not limited to reflective film, and the film application object is not limited to photovoltaic glass, backsheet, etc. in solar cells; the specific design can be adjusted according to actual conditions. Similarly, the shape of the anti-sticking roller is not limited to cylindrical, but can also be other shapes; the surface of the anti-sticking roller can be a granular surface, an uneven surface, or a smooth surface, etc.
[0052] The anti-sticking roller of the photovoltaic film applicator of this embodiment effectively prevents the reflective film from sticking to the anti-sticking roller during operation by stacking an isolation layer 3 and an anti-sticking layer 4 from the inside to the outside on the roller body 2, and by using air blowing holes 6 that penetrate the roller body 2, hub 1, isolation layer 3, and anti-sticking layer 4. This avoids deformation of the reflective film, and the air pressure applied to the reflective film through the air blowing holes 6 makes the reflective film adhere more tightly to the surface of the object to be filmed. The adsorption holes 5 that penetrate the roller body 2 and hub 1 for adsorbing the anti-sticking layer 4 prevent the anti-sticking layer 4 from moving relative to the roller body 2, further preventing the reflective film from moving during the application process. At the same time, by stopping the air intake of the adsorption holes 5, the anti-sticking layer 4 can be replaced conveniently and quickly, facilitating the maintenance of the anti-sticking roller.
