Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, and more specifically, to a cooling roller assembly and coating equipment. Background Technology

[0002] In the field of thin film material production and processing, coating technology is widely used to endow thin films with special functions such as wear resistance, corrosion resistance, and optimized optical properties, so as to meet the diverse needs of different industries for thin film materials.

[0003] However, existing thin-film coating equipment has the following problems during use:

[0004] Traditional thin-film coating equipment often suffers from insufficient and ineffective cooling after coating, leading to weak adhesion between the coated layer and the film, and a tendency for delamination. Furthermore, most of these cooling systems employ a single cooling roller or a simple cooling structure, resulting in low cooling efficiency and failing to meet the demands of rapid production. Moreover, a single cooling roller struggles to ensure temperature uniformity throughout the cooling process, easily causing deformation and stress concentration due to excessive localized temperature differences. For example, in the production of some optical films, deformation caused by uneven temperature can significantly reduce the film's optical performance, failing to meet the requirements of high-precision optical instruments and impacting its functionality.

[0005] This invention achieves stable unwinding of the film using an unwinding frame. Auxiliary rollers one and two guide and adjust the film's orientation, maintain tension and flatness, while cooling rollers one and two cool the film in stages. This ensures that the film is coated at a suitable temperature, and that the coating layer adheres firmly, thereby improving product quality, effectively increasing production efficiency, and meeting the diverse needs of different film materials and coating processes.

[0024] The utility model discloses a fixed frame one 2 right -end fixed mounting has the extension plate 202, rotates and is installed with the auxiliary roll no. 203 in the extension plate 202 inside, and the auxiliary roll no. 203 height is higher than cooling group roll no. 201, and the film box 4 left and right two ends all are set up with the inlet and outlet groove 401, and the film box 4 fixed mounting is in the fixed groove 204 of fixed frame one 2 middle part, when the film leaves cooling group roll no. 201, the film moves to the auxiliary roll no. 203 upwards, owing to the auxiliary roll no. 203 height is higher than cooling group roll no. 201, it changed the transmission direction of film, made the film with proper angle downward transmission and moved to cooling group roll no. 301 place, and this design helps the film to keep proper tension and flatness, and when downward transmission, the film is turned over, makes cooling group roll no. 301 can carry out cooling to the other side of film.

[0025] Working principle: At the beginning of the work, the film roll is properly placed on the unwinding roller 102 of the unwinding frame 1. The controller 101 on the front of the unwinding frame 1 plays a key role, which can accurately control the rotation speed and acceleration of the unwinding roller 102. Under the instruction of the controller 101, the unwinding roller 102 starts to rotate smoothly and releases the film slowly. The film comes to the auxiliary roller one 104 on the right side above the unwinding roller 102. The auxiliary roller one 104 plays an important role in guiding the film to ensure its smooth entry into the next process. It can also preliminarily adjust the tension and direction of the film. By adjusting the position and rotation state of the auxiliary roller one 104, problems such as film relaxation and deviation in the initial stage can be effectively avoided, laying a foundation for the stable operation of subsequent processes. After the film comes out of the auxiliary roller one 104, it enters the fixed frame one 2 area. At this time, the motor 501 on the front support plate 5 of the fixed frame one 2 starts to rotate. The driving wheel 502 at the output end of the motor 501 starts to rotate. Since the driving wheel 502 is meshed with the driven wheel 503 above, the rotation of the driving wheel 502 will drive the driven wheel 503 to rotate synchronously. The connecting rods 504 at the rear ends of the driving wheel 502 and the driven wheel 503 are fixedly connected with the cooling group roller one 201 on the left and right sides inside the fixed frame one 2, respectively, so that the cooling group roller one 201 starts to rotate under the drive of the connecting rods 504. After the cooling group roller one 201 rotates, it guides the film to pass through the middle. In this process, the cooling group roller one 201 plays multiple roles. First, it has cooling function, which can simultaneously cool the upper and lower sides of the film, making the temperature of the film rapidly decrease to a range suitable for coating, which is crucial for ensuring the quality of coating. Second, the rotation speed of the cooling group roller one 201 and its rolling effect on the film surface can make the film maintain appropriate tension and flatness. Appropriate tension can prevent the film from wrinkling and relaxing during transmission, while a flat film surface helps to ensure the uniformity of subsequent coating. After the film comes out of the cooling group roller one 201, it enters the coating box 4 through the inlet and outlet slot 401 on the left side of the coating box 4. Inside the coating box 4, the film undergoes a series of coating processes, such as evaporation coating or sputtering coating, according to actual needs. In the evaporation coating process, the coating material is heated and evaporated, and the gaseous coating material molecules move and deposit on the film surface in a vacuum, forming one or more coating layers. In the sputtering coating process, the target atoms are sputtered by ion bombardment and deposited on the film surface. No matter which coating method is used, the goal is to form a coating layer with specific properties on the film surface, such as improving the wear resistance, corrosion resistance, and optical performance of the film. After coating, the film comes out of the right side of the coating box 4 and moves up to the auxiliary roller two 203 inside the extension plate 202 on the right end of the fixed frame one 2.Since the auxiliary roller two 203 is higher than the cooling group roller one 201, it skillfully changes the transmission direction of the film, so that the film is transmitted downward at a proper angle and enters the area of the fixing frame two 3. The cooling group roller two 301 on the left and right sides inside the fixing frame two 3 also rotates through the linkage of the motor 501, the driving wheel 502, the driven wheel 503 and the connecting rod 504. The film moves on the cooling group roller two 301, and the cooling group roller two 301 further cools the plated film, which plays a key role in solidifying the plated film layer. It can make the plated film layer and the film better combined, enhance the adhesion and stability of the plated film layer. At the same time, the cooling effect of the cooling group roller two 301 can also prevent the film from deforming, shrinking and other problems due to the heat generated during the plating process, ensuring the dimensional stability and surface quality of the film. In addition, since the auxiliary roller two 203 turns the film when guiding the film to transmit downward, the cooling group roller two 301 can cool the other side of the film, further improving the uniformity of the cooling effect. After being treated by the cooling group roller two 301, the film continues to transmit forward and finally reaches the winding roller 103 in the unwinding frame 1. The winding roller 103 rotates at a proper speed under the control of the controller 101. The controller 101 will adjust the rotating speed of the winding roller 103 in real time according to the material, thickness of the film and the tension change in the whole production process, etc., to ensure that the tension of the film during winding process always remains in a proper range. The winding roller 103 gradually winds up the film to form a roll of finished product with plated film.
