Automatic stamping machine

Abstract

Disclosed is an automatic stamping machine. The automatic stamping machine comprises a machine frame, a stamp rotating shaft, a rolling rotating shaft, a driving mechanism, an automatic ink adding mechanism, a stamp ink box and a locating locking device. The stamp rotating shaft and the rolling rotating shaft are arranged on the machine frame in parallel in a rotating mode, and the stamp rotating shaft is located below the rolling rotating shaft. At least one rolling stamp is arranged on the stamp rotating shaft, and a rolling printing roller which corresponds to the rolling stamp in position is arranged on the rolling rotating shaft. The driving mechanism is installed on the machine frame and drives the stamp rotating shaft and the rolling rotating shaft to synchronously rotate in the opposite directions. The automatic ink adding mechanism automatically adds ink to the stamp ink box. First rolling wheel printing cotton which makes flexible contact with the rolling stamp is arranged in the stamp ink box. The machine frame and a printer are located and locked through the locating locking device. According to the automatic stamping machine, the relative position between the automatic stamping machine and the printer is accurately guaranteed through the innovative locating locking device, the probability of paper jams is reduced, and the stability and the reliability are improved. The first rolling wheel printing cotton makes flexible contact with the rolling stamp, and the service life is long. The automatic ink adding mechanism can achieve automatic and continuous ink addition.

Description

technical field [0001] The invention relates to an automatic sealing machine. Background technique [0002] At present, many batch bills and receipts that need to be stamped are mostly printed out in batches first, and then manually stamped one by one after checking, which is a waste of manpower and time. With the progress of society, customers need legal bills and certificates to protect their rights and interests, which also poses a requirement for the existing self-service printing service terminals to have problems such as official seals without service seals. In this context, the automatic stamping machine came into being. The deficiency of existing automatic stamping machine is: [0003] (1) The existing automatic stamping machine is usually fixed directly at the paper outlet of the printer, and precise positioning cannot be achieved during assembly, so paper jams and other phenomena are prone to occur; when either the printer or the automatic stamping machine fails,...

AI Technical Summary

Problems solved by technology

[0003] (1) The existing automatic stamping machine is usually fixed directly at the paper outlet of the printer, and precise positioning cannot be achieved during assembly, so paper jams and other phenomena are prone to occur; when either the printer or the automatic stamping machine fails, it must be repaired When it needs to be disassembled for maintenance, when it is reassembled, there will be a possibility that the paper cannot be conveyed normally

[0004] (2) The existing automatic stamping machine usually adopts the clutch control method, because the clutch and the motor are connected through gears, so the possibility of mechanical lock failure is increased, and the cost is also increased

[0005] (3) When the rotating shaft drives the stamp to rotate and stamp, it is in rigid contact with the roller printing cotton and the paper drive wheel, which will reduce the service life of the automatic stamping machine

[0006] (4) Existing automatic stamping machines generally use sponge wheels to store oil. As the amount of oil on the sponge wheel gradually decreases, the quality of stamping also gradually declines, so manual refueling is required, but the stamping after each refueling The number is limited, and the refueling operation is relatively cumbersome

The disadvantage of this mechanism is that after the ink is introduced into the ink box, the ink is introduced into the bottom of the ink box from one side of the ink box, so it is easy to be completely absorbed by one side of the printing cotton, while the other side cannot absorb it. Half of it can be oiled, and in the end, only half of the stamp can be stamped; if the printed cotton is to absorb all the oil, it needs to add a lot of oil, but if the printed cotton absorbs more oil, the seal will be coated with thicker ink. will affect the seal effect
