The printing ink rubber head 200 includes a plug rod 210, an abutting sleeve disc 220 and a spring 230. The spring 230 is fixedly installed on the surface of the plug rod 210 and its top end is fixedly connected to the bottom surface of the abutting sleeve disc 220. The abutting sleeve disc 220 is slidably sleeved on the surface of the plug rod 210. A lock ear disc 211 is provided at the top end of the plug rod 210, and a limit insertion hole 212 opposite to the limit insertion ear 120 is provided inside the lock ear disc 211. The outer diameter of the lock ear disc 211 is greater than the outer diameter of the plug rod 210. A driving rod 310 for driving the unlocking lifting ring 300 to perform a jacking movement is embedded and installed on the top surface of the rubber seat cover 100.

[0025] In this embodiment, the unlocking lifting ring 300 is annular, and its inner diameter is greater than the outer diameter of the lock ear disc 211, and the outer diameter of the unlocking lifting ring 300 is less than the inner hole diameter of the rubber seat cover 100.

[0026] In this embodiment, the lock piece ear 130 is of a fan-shaped structure, and an arc groove for abutting against the surface of the plug rod 210 is provided at one end of the lock piece ear 130.

[0027] In this embodiment, the limiting lug 120 is located on the central axis of the rubber seat sleeve 100 and is used to be sleeved inside the limiting jack 212 to guide the stamping movement of the plug rod 210. A positioning pin adapted to the bottom surface of the rubber seat sleeve 100 is provided on the top surface of the abutting disc 220, and a positioning jack adapted to the positioning pin on the top surface of the abutting disc 220 is provided on the bottom surface of the rubber seat sleeve 100.

[0029] The working principle and usage process of the present utility model:

[0030] During the insertion process of the rubber head of the printing machine, the plug rod 210 is inserted into the inner side of the rubber seat sleeve 100 through the locking ear disc 211 at the top end of the plug rod 210 and the limiting jack 212. Until the locking ear disc 211 passes through the locking piece ear 130, the limiting jack 212 is sleeved on the end of the limiting lug 120. The plug rod 210 is engaged with the rubber seat sleeve 100 by the limit of the locking piece ear 130 and the locking ear disc 211 and is locked;

[0031] During the stamping process, the spring 230 can retract to a certain extent. During this retraction process, the surface of the contact lens is protected by the elastic contraction buffer of the spring 230 to avoid damage during the stamping process;

[0032] During the unlocking process, the unlocking lifting ring 300 is pushed by the driving rod 310 to lift, so that the unlocking lifting ring 300 pushes the locking piece ear 130 to deflect upward. The end of the locking piece ear 130 is separated from the abutting effect with the locking ear disc 211, and the plug rod 210 can automatically fall by gravity and the elastic recovery of the spring 230 to quickly unlock and fall off.
