Abstract

The invention discloses a mechanical seal device of a gas cap reeling and unreeling mechanism. The mechanical seal device comprises a shaft sleeve (1). One end of the shaft sleeve (1) is provided with a gear shaft sleeve (2) which can be sheathed, a tension device is arranged between the gear shaft sleeve (2) and the shaft sleeve (1), the tension device comprises a first fixed base (3) and a second fixed base (4), the first fixed base (3) is fixed in the shaft sleeve (1), the second fixed base (4) is fixed in the gear shaft sleeve (2), a spring is arranged between the first fixed base (3) and the second fixed base (4), one end of the spring (5) is provided with a spring seat (6) used for fixing the spring, the bottom surface of the spring seat (6) is tightly fitted with the upper surface of the first fixed base (3), and the other end of the spring (5) is in a movable connection with the second fixed base (4). The mechanical seal device of the gas cap reeling and unreeling mechanism has low cost and convenience of maintenance and is not easy to damage.

Description

technical field [0001] The invention relates to a printing machine, in particular to a mechanical seal device on an air top rewinding and unwinding mechanism on the printing machine. Background technique [0002] At present, the air cap unwinding and unwinding mechanism is one of the necessary mechanisms for printing machines, coating machines and other machines involving the use of roll materials. At present, the air top retracting and unwinding mechanism includes a rotary arm, and the rotary arm is provided with a cylinder and a main shaft. The inner wall of the rotary arm is also provided with a mechanical seal. The telescopic axial gear sleeve, the main shaft is connected with the cylinder through a mechanical seal device, so that the use of two gear sleeves at a time not only wastes the cost, but also is easy to damage and troublesome to maintain. Contents of the invention [0003] The present invention aims to solve the problems of high cost, easy damage and troubl...
