Description

An automatic stamping machine

technical field

The invention relates to the technical field of stamping, in particular to an automatic stamping machine.

Background technique

With the development of the times, the current seal is widely used in various departments and industries such as the government, banks, schools, and enterprises, and is the most effective legal document. Seals are widely used in various departments and industries. Nowadays, the seals used by various units are basically manually operated, which is time-consuming and labor-intensive. When encountering large quantities of regular materials that need to be stamped, manual stamping is even more inefficient. In addition, due to artificial accidental factors or fatigue caused by long-time stamping, the seal imprint may be deformed or unclear.

Although there are some automatic stamping devices on the market, such as Chinese patent CN201510894974.3, a stamping device is disclosed. To realize the up and down movement, the device can only hold one stamp, and cannot realize simultaneous work of various types and multiple stamps. And this device uses cylinder, needs to use air pump to carry out air supply, and noise is big, thereby reduces the high-speed automation of stamping machine. Moreover, the existing automatic stamping device can only stamp documents with a fixed paper size, and the requirement for the paper size is too single, and this solution cannot realize stamping for documents with different paper sizes. Ink ink is required for stamping. In the existing automatic stamping device, when the ink on the stamp is insufficient, it needs to be dismantled and manually applied with ink, which is particularly inconvenient, time-consuming and laborious, and severely limits the use of the brake stamping device. As an important part of the automatic stamping machine, the clamping device plays a pivotal role, but as mentioned, although the existing clamping device has realized the clamping of the seal, its clamping chapters are targeted, and the installation is complete. Finally, the clamping device cannot be self-adjusting, and cannot adapt to the situation of different heights of various types of stamps.
