Background

In order to effectively manage the seal and monitor the use of the seal, more and more mechanisms begin to use the seal machine to realize the closed keeping of the seal and the electronic monitoring and management of the seal using process;

at present, various printers have been developed. For example, some stamping machines use a rotatable stamp magazine to hold the stamp, and during stamping, the stamp magazine is rotated to rotate the desired stamp directly under the stamping head, and the stamping head presses the stamp, thereby completing the stamping process. Some stamping machines do not use a special stamp library, but adopt a stamp actuating mechanism similar to a gripper to select a stamp, and when the stamp is used, the stamp actuating mechanism moves to the position above the required stamp to pick up the stamp and then moves to the position where the stamp is required to be used for stamping. Different printing machines have advantages and can be selected for use according to specific printing requirements;

in the above-described stamp using a stamp magazine to hold a stamp, it is common to hold the stamp in a stamp holder and then set the stamp holder in the stamp magazine. The use of the seal fixture can not only match the shape of the seal, but also enable the seal to move up and down, thereby being convenient for using the seal. Different seal fixtures have different advantages and disadvantages in structure and function, but in practical production situations, different seals are needed to be used, such as a circular seal shown in fig. 7 and a square seal shown in fig. 8, so that one seal fixture is designed to be used under different seal situations.
