Description

TECHNICAL FIELD

[0001] The present application relates to a production equipment for making cast film, in particular to a flow forming machine for solar photovoltaic cell packaging adhesive film. BACKGROUND

[0002] At present, the solar photovoltaic cell packaging adhesive film flow forming equipment mainly includes a film extrusion die and a plurality of pairs of mutually counter-rolling steel rollers and rubber rollers constituting a counter-rolling cylinder pair. The main function of the counter-rolling cylinder pair is to cool and shape the extruded adhesive film and to press the adhesive film pattern. For example, the applicant has applied for and obtained a patent for "high-precision temperature control film flow forming machine", patent number: 202110783485.6. In the invention, the extruded film of the film extrusion die first enters the counter-rolling roller pair of the rubber roller and the steel pattern roller, and then passes through the frosted roller and the cooling roller to complete the flow forming of the adhesive film. Although the structure can press the surface pattern of the film by the counter-rolling of the rubber roller and the steel pattern roller, the temperature of the molten film extruded from the extrusion die is relatively high, and the heat transfer property of the rubber roller is poor. Therefore, the roller speed must be slowed down to achieve the purpose of cooling and shaping the extruded film. This not only reduces the forming quality of the extruded adhesive film, but also restricts the rotation speed of the rubber roller and the steel roller, directly affecting the production efficiency of the flow forming machine.

[0003] In view of the above shortcomings, the applicant has applied for "EVA adhesive film speed-increasing flow forming machine" on January 18, 2023, application number: 202310067310.4. The adhesive film flow forming machine of this application first passes through two pairs of cooling rollers for cooling and shaping, and then performs pattern pressing and shaping. This structure improves the rotation speed of the flow forming roller and the operating efficiency of the flow forming machine to a certain extent.

[0004] The existing film casting equipment is still in the structure of cooling by rotating cooling roller, so there are some obvious deficiencies no matter the embossing is processed on the roller before cooling or the embossing is processed on the roller after cooling. Firstly, the contact angle and arc length of the rubber film with the cooling roller are fixed, so the cooling time is prolonged by reducing the rotating speed of the cooling roller to achieve the ideal cooling effect, and the reduction of the rotating speed of the cooling roller will inevitably reduce the running efficiency of the casting machine, so the existing structure of cooling by the cooling roller has become the bottleneck of the production efficiency of the casting machine. Moreover, the rubber film extruded from the extrusion die still has a high temperature, so the direct embossing contact between the molten rubber film and the roller pair is easy to cause the adhesion between the rubber film and the roller, so that the surface flatness of the rubber film is low, wrinkles and burst are generated, the yield is reduced, and the raw material is wasted seriously. Furthermore, the ambient temperature of the molten rubber film extruded from the extrusion die will directly affect the quality of the rubber film, and improper temperature control will cause the modification of the raw material to be not in place, the coupling activation to be insufficient, the stress of the rubber film to be uneven, and the rubber film to be easy to generate wrinkles, cracking, even holes and other defects. Obviously, the existing rubber film casting machine does not pay attention to the molding characteristics, so the quality of the rubber film product is restricted. SUMMARY

[0005] In view of the above deficiencies of the prior art, the technical problem to be solved by the present application is to provide a high-speed rubber film casting machine which can effectively improve the production efficiency of the casting film and ensure the stability of the production quality of the casting film.

[0007] Further, the cooling roller one and the cooling roller three are respectively arranged on the front and rear sides of the cooling roller two; and the embossing pattern on the outer surface of the cooling roller two is matched with the pattern structure on the surface of the rubber film conveying belt.

[0008] Further, the rear side of the cooling roller one is also provided with an auxiliary cooling roller two and an auxiliary cooling roller one, which are rotationally supported on the roller support.

[0016] In the technical scheme of the present application, since the rubber film conveying belt is wound around the cooling roller set, the tensioning roller set and the conveying belt deviation rectifying device, the rubber film extruded by the extrusion die in a relatively high temperature and in a molten state does not directly enter the cooling roller for cooling, but enters the rubber film conveying belt for temperature control, flow casting and setting. On the one hand, the molten rubber film can obtain sufficient rubber film setting time and setting path length on the conveying belt, without being limited by the cooling angle size and the cooling angle arc length of the cooling roller, so that the conveying speed of the rubber film on the conveying belt can be greatly increased, thereby greatly improving the flow casting operation efficiency of the flow casting machine.

The cooling roller two 17 located in the middle position is a steel roller, and a embossed pattern is formed on the outer cylinder surface of the steel roller, which corresponds or is the same as the embossed pattern of the rubber film conveyor belt 22. The outer cylinder surface of the cooling roller three 18 and the cooling roller two 16 is coated with a rubber layer, and the material and structure of the rubber layer are the same as those of the prior art. The cooling roller three 18, the cooling roller two 17 and the cooling roller one 16 are all transmissionally connected with the corresponding roller drive motor. Or at least one roller is transmissionally connected with the corresponding roller drive motor.

[0033] The guide roller two 9 and the guide roller three 11 are also rotatably supported between the two side wallboards of the roller bracket 10.

Then, it passes through the rolling points of the opposing cooling rollers 17 and 18 and successively passes over the lower cylinder surface of the cooling roller 17 and the upper cylinder surface of the cooling roller 16. After passing over the lower cylinder surface of the auxiliary cooling roller 15 and the upper cylinder surface of the auxiliary cooling roller 14, it becomes a molded adhesive film with an embossed texture.

Narrow inlet and outlet ports are respectively provided on the end plates at both ends of the rectangular tube structure of the temperature control box 201 for the film conveyor belt 22 and the film 13 on it to pass through and exit.

The number of temperature control unit cavities divided by the upper and lower temperature control cavities is not limited to three, but should be determined according to the specific design conditions. The temperature control unit cavities can form uniform temperature control air flow through the uniformization of the cavities.
