Description

Technical Field

[0001] The present application relates to the technical field of EVA photovoltaic adhesive films, and specifically to a split steel roller structure. Background Art

[0002] EVA photovoltaic film is a material used in the manufacturing process of solar panels. EVA is the abbreviation of ethylene vinyl acetate copolymer, which has excellent transparency, weather resistance and bonding properties. EVA photovoltaic film is used to improve the light absorption efficiency of solar panels and the stability of battery modules. At present, film machines are often used to install EVA photovoltaic film on solar panels.

[0003] For example, the utility model patent with publication number CN205685622U specifically discloses an EVA film molding device for photovoltaic modules and the EVA film produced therefrom. The device can better control the edge thickness and edge shrinkage rate of the EVA film produced therefrom. While molding the EVA film, the logo representing the specification characteristics of the EVA film can be pressed on the surface of the EVA film, which is convenient for distinguishing between the EVA film material turnover intervals and avoiding the increase in production costs caused by using different edge pattern cutters.

[0004] However, in the above patent, the device prints the EVA film by setting up multiple sets of molding rubber rollers and molding steel rollers. However, most of these steel rollers are integrated, so that the printed pattern on them cannot be changed. When a certain printing on the steel roller is damaged by external force, the steel roller needs to be replaced as a whole, which increases the processing cost of the device. Therefore, it is necessary to provide a split steel roller structure to solve the above problem.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] The technical solution adopted by the present application to solve its technical problems is: a split steel roller structure, including a pressure roller, the pressure roller includes a roller body; a printing layer, the printing layer includes a first connecting block and a second connecting block, the first connecting block and the second connecting block are provided with an arc-shaped installation cavity inside, the diameter of the installation cavity is the same as the diameter of the roller body; a mounting shaft, a fixed plate is provided on one side of the mounting shaft, and the roller body and the printing layer are clamped between two sets of fixed plates.

[0008] Furthermore, both ends of the roller body are provided with latching teeth, and positions on the mounting cavity corresponding to the latching teeth are provided with latching grooves, and the latching grooves are adapted to the latching teeth.

[0009] Furthermore, a convex block is provided on a side of the first connection block close to the roller body, and a concave block is provided on a side of the second connection block opposite to the first connection block, and the sizes of the convex block and the concave block are matched.

[0010] Furthermore, threaded holes are recessed inwardly at both ends of the roller body, and a screw rod is arranged on the fixing plate, and the screw rod is matched with the threaded hole.

[0011] Furthermore, a sponge pad is provided on one side of the fixing plate close to the roller body.

[0012] The beneficial effect of the present application is that a split steel roller structure provided by the present application, by setting a split pressure roller, makes it possible for when the printing on a certain printing layer of the pressure roller is worn or damaged, only the corresponding printing layer needs to be replaced, without replacing the entire pressure roller, thereby reducing the replacement cost of the device and increasing the practicality of the device.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] like Figure 1 As shown, the present application provides a split steel roller structure, including a film laminating machine 1, which is arranged in a solar panel processing factory. A feed port 11 is arranged at one end of the film laminating machine 1, and the feed port 11 is used to receive the EVA film transported from the outside. At the same time, a pressure roller 2 is arranged at the feed port 11, and the pressure roller 2 is used to print the EVA film. At the same time, a film laminating mechanism 12 is arranged on the inner side of the film laminating machine 1, and the film laminating mechanism 12 is used to install the processed EVA film on the solar panel.

[0023] like Figure 2 As shown, the pressing roller 2 is made of metal material, and the pressing roller 2 is split, and each of its components can be disassembled and replaced separately, including a roller body 21 located in the center, and a printing layer 22 is arranged on both sides of the roller body 21, and the printing layer 22 is used for pressing and printing the EVA film, and an arc-shaped installation cavity 221 is arranged inside the printing layer 22, and the diameter of the installation cavity 221 is the same as the diameter of the roller body 21, and when two groups of printing layers 22 are installed on the roller body 21, the roller body 21 is located between the two groups of installation cavities 221;

[0024] Both ends of the roller body 21 are provided with latch teeth 24, and at the same time, a latch groove 222 is provided on the installation cavity 221 at a position corresponding to the latch teeth 24. The latch groove 222 is adapted to the latch teeth 24. When the printing layer 22 is installed, the latch grooves 222 at both ends of the printing layer 22 are installed on the latch teeth 24. The arrangement of the latch groove 222 and the latch teeth 24 guides the printing layer 22 during installation, thereby allowing the printing layer 22 to be installed at a suitable position.
