Description

Technical Field

[0001] The utility model relates to the technical field of smart cards, in particular to an anti-settling device for coating liquid used in making pre-coating films of smart cards. Background Art

[0002] A smart card is a plastic card with a microchip embedded in it. This card is usually the size of a credit card, i.e. 85.5*54mm, and is equipped with components such as a CPU, RAM, and ROM. Smart cards exchange data through a reader / writer and can process large amounts of data on their own without interfering with the operation of the host CPU. Smart card technology has a wide range of applications, including but not limited to mobile communications, public transportation, medical insurance, identity recognition, security control, payment, etc. When producing smart cards, a coating liquid is used to coat the card. The pre-coating liquid can greatly improve the quality of the smart card. Currently, there is an anti-settling device for the coating liquid used in the production of pre-coated films for smart cards on the market, but it still has some disadvantages.

[0003] The existing anti-sedimentation device for coating liquid used in the production of pre-coated films for smart cards uses a spiral stirring belt to stir the coating liquid in the coating liquid cylinder to prevent sedimentation. However, the spiral stirring belt only rotates in the middle of the coating liquid cylinder, ignoring the problem that the inner wall will stick to the liquid. At the same time, if the coating liquid cylinder is not cleaned for a long time, it will affect the subsequent use. For example, the Chinese utility model patent with the authorization announcement number CN220990407U discloses an anti-sedimentation device for coating liquid used in the production of pre-coated films for smart cards, including a coating liquid cylinder and an anti-sedimentation component; the anti-sedimentation component includes a bracket, two support seats, and two connecting The device comprises a connecting shaft, two connecting pieces, a rotating shaft, a spiral stirring belt, and a reduction motor; a bracket supports the two support bases of the coating liquid cylinder and the reduction motor; a connecting shaft is rotatably installed in each support base, and both connecting shafts pass through the coating liquid cylinder. A rotating shaft is installed inside the coating liquid cylinder via two connecting pieces. The reduction motor is connected to the connecting shaft on the left side, and the reduction motor provides power, ultimately driving the rotating shaft to rotate. The rotating shaft drives the spiral stirring belt to rotate, stirring the coating liquid inside the coating liquid cylinder to prevent sedimentation, thereby maintaining the coating liquid uniformity, thereby stirring the coating liquid and avoiding quality problems caused by uneven coating liquid. However, this device uses a spiral stirring belt to stir the coating liquid in the coating liquid cylinder to prevent sedimentation, but the spiral stirring belt only rotates in the middle of the coating liquid cylinder, ignoring the fact that the inner wall will stick to the liquid. At the same time, if the coating liquid cylinder is used for a long time without cleaning, it will affect its subsequent use. In addition, the stirring rod continues to operate at high speed, which will shorten its service life. Therefore, we propose an anti-settling device for coating liquid used in the production of smart card pre-coating film to solve the above-mentioned problems. Utility Model Content
