Description

Technical Field

[0001] The utility model relates to the technical field of plastic films, and particularly relates to a storage device for plastic film limit samples. Background Art

[0002] Plastic film products occupy a large share in the market and are widely used in fields such as food, medicine, chemical industry, machinery, and hard brushes. With the continuous expansion of the application fields of films, people's requirements for the performance and appearance of films are also getting higher and higher. Especially in high-end fields such as 5G communication, electronic display, and automotive batteries, the physical property requirements and appearance requirements for films are also gradually increasing. Since there is currently no good quantification method for the appearance of many plastic films. Therefore, in many cases, physical objects are needed as limit samples, and film manufacturers will also compare the products produced during the production process with the limit samples to ensure that the appearance meets the requirements of customers. The existing devices for storing films only target the storage of film rolls. When storing limit samples, since the film itself is very thin, scratches, abrasions, creases and other mechanical damages are easily generated during the storage of a single limit sample, which will change its original appearance.

[0003] For example, patent applications CN202320318347 and CN201720201113 disclose a plastic film storage device, but these devices can only be used to store film roll samples, and during storage, due to external forces on the film roll samples, the film is in a wound state for a long time, and the apparent morphology of the film will change, which is not conducive to being a storage device for limit samples.

[0004] For example, patent application CN201921738455 discloses an optical film storage device, which includes a storage box, in which several storage boxes are arranged up and down and slide back and forth. The top of the storage box is open, and several sliding moving clamping plates are arranged at intervals on the inner bottom of a group of adjacent side walls close to it. One side of the bottom of the storage box is provided with an air inlet fan, the air inlet of which is provided with an air suction pipe, and the air outlet is communicated with the side wall of the bottom of the storage box through an air inlet pipe. Filter drying layers are arranged at the ends of both the air suction pipe and the air inlet pipe. An air outlet fan is arranged on one side of the top of the storage box away from the air inlet fan, the air inlet of the air outlet fan is communicated with the top of the storage box, a humidity sensor is arranged on the inner top wall of the storage box, and a controller is arranged on the outer wall of the storage box. However, this device only considers the storage environment of the film and does not consider the contact between films during the storage process, which will affect the appearance state of the film and is not conducive to being a storage device for limit samples.

[0005] In the actual production process, the well-known method in the art is to directly store multiple layers of A4 samples in a sample bag. However, this method is very likely to have mechanical damages such as creases and scratches during storage, which can easily damage the original film appearance, and it is not easy to take, and more mechanical damages are likely to be caused during the taking process, damaging the film appearance.
