The spring-type seal should be pressed inward with appropriate force, and then the official seal should be tightened in a clockwise direction. The official seal will usually retract automatically at this time and close automatically. The installation method of the spring seal is to first tear off the rubber of the seal, then align the head of the seal with the handle of the seal, and stick it firmly.

The working principle of the spring-type seal

When powered on, the system recalibrates the positioning of each part, and the control system sends an initialization signal to control the electric push rod and seal to reach the initial zero stroke position. When placing the file, the operator puts the file into the file compartment of the designated stamping machine. After closing it, click the location to be stamped on the screen. After receiving the instruction, the intelligent camera module in the stamping machine will automatically capture the file information and send it to the leader. Conduct review.

During the process of picking up the ink pad, it is detected that the document is in place and the leader has authorized the equipment to stamp. The electric stamping push rod extends downward, and the spring drives the stamp to move downward to pick up the ink pad. The sensor on the electric putter body detects whether the putter is extended in place. After extending the sealing position, the electric push rod for stamping is powered in the opposite direction, causing the seal to shrink upward and reach the position, completing the process of sealing and removing mud.

In the reset process, after completing the stamping process, the stamping electric actuator expands and contracts in the reverse direction. The No. 1 stepper motor is powered by reverse rotation, and the seal moves backwards and returns to its original position, and the sensor detects whether it is completed. After the sensor detects and completes the sealing operation, the electronically controlled lock of the document bin automatically unlocks, and the staff can open the document bin and take out the documents.
