Specific embodiment
The working principle and its related details of the utility model are further described with reference to the accompanying drawing, referring to attached drawing, this kind
The transmission mechanism of printing machine includes input shaft 1 and output shaft 4, and the input shaft 1 is sequentially connected with output shaft 4, transmission connection
It can be sequentially connected using gear drive connection or transmission belt, see attached Fig. 1 and 2, in the present embodiment, installed on the input shaft 1
There is input sprocket 8, output chain gear 9 is installed on the output shaft 4, transmission belt is transmission chain 2, and the setting of transmission chain 2 is in input chain
On wheel 8 and output chain gear 9；Transmission switch is provided on the output shaft 4, the transmission switch includes constant speed connector
7, speed change connector 3 and the switch piece 5 moved on output shaft, one end of the switch piece 5 are matched with constant speed connector 7, institute
The other end for stating switch piece 5 is matched with speed change connector 3, and output wheel 52 is equipped on the switch piece 5, i.e. switch piece 5
When one end is matched with constant speed connector 7, the other end of switch piece is then separated with speed change connector 3, is cut by the drive of constant speed connector 7
The rotation of part 5 is changed, then the output of output wheel 52 is exactly constant speed, if switch piece 5 is matched with speed change connector 3, is connected with constant speed
Fitting 7 separates, and drives switch piece 5 to rotate by speed change connector 3, then the output of output wheel 52 is exactly speed change；The output wheel
52 can use single channel sprocket wheel can also be with two-way sprocket wheel according to device requirement；Driving switch piece 5 moves axially on output shaft
Power part can be using one kind of cylinder or motor, and in the present embodiment, the power part 6 includes driving lever 62 and driving driving lever
The cylinder 63 of swing, one end of the driving lever 62 and switch piece 5 link, and cylinder 63 pushes driving lever 62, and the swing of driving lever 62 then drives
Switch piece 5 moves on output shaft 4.Open up fluted 71 on the constant speed connector 7, one end of the switch piece 5 have with
Groove is placed in groove 71 to matched convex ribs 51, the convex ribs 51, then switch piece 5 is matched with constant speed connector 3, the two connection
Dynamic, equally, the speed change connector and switch piece can also be realized using above-mentioned structure and be linked, i.e., the described speed change connector 3
On open up fluted 31, the other end of the switch piece 5 has with the groove to matched convex ribs.
