Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of hot stamping devices, and more specifically, to a card embossing hot stamping module. Background Art
[0002] When financial cards are made, the card numbers are often made into embossed characters. In order to improve the recognition and appearance of the card numbers, it is necessary to perform hot stamping on the embossed surface, which makes the hot stamping module a common module in the bank card production process. However, the thickness and material of the cards currently on the market vary, and the embossing process will also make the cards uneven.
[0003] The existing card hot stamping modules all transmit the power of the eccentric wheel pressing motor to the eccentric wheel through the eccentric wheel transmission mechanism, so that the eccentric wheel rotates cyclically. During the cyclic rotation, the eccentric wheel also presses the heating component downward, causing the heating component to move downward and hot stamp the color material on the good color ribbon on the convex characters of the card.
[0004] In the hot stamping process, the existing card hot stamping module only controls the up and down movement of the heating component by the rotation of the cam. Therefore, the up and down stroke of the heating component is fixed, which makes it unable to adapt to cards of different thicknesses and unevenness. When the thickness of the cards is different, the pressure they are subjected to is different. If the pressure is too large, it will affect the height of the embossed characters, making the card not meet the card making requirements and reducing the card quality.
[0005] Therefore, there is an urgent need for a card embossing and hot stamping module that can realize hot stamping of cards of different thicknesses and unevenness. Utility Model Content
