Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Referring to figs. 1 to shown in Fig. 2, an a kind of embodiment of printing stretching degree electric adjusting apparatus of the invention, including adjust
Complete machine structure and fixed frame 13, adjustment mechanism are fixed on fixed frame 13, and adjustment mechanism includes stepper motor 1, scraper lifting shaft 12
With stretching degree adjusting set 6, stepper motor 1 is fixed in stretching degree adjusting set 6 by fixing axle 5, is arranged on scraper lifting shaft 12
There is lift adjustment screw rod 11, shaft coupling 2, scraper lifting shaft 12 and liter are provided between stepper motor 1 and lift adjustment screw rod 11
The connection type of falling tone section screw rod 11 is to be threadedly coupled, and the rotary motion of lift adjustment screw rod 11 can be become scraper lifting shaft
12 vertical movement, the position that scraper lifting shaft 12 is corresponded on 6 surface of stretching degree adjusting set are provided with lift span 15, lift span 15
It is inside provided with directive wheel 9, directive wheel 9 is arranged on scraper lifting shaft 12.
In use, stepper motor 1 moves, lift adjustment screw rod 11 is driven to make rotating motion by shaft coupling 2, due to locking
The presence of nut 3 and rolling bearing 4 makes lift adjustment screw rod 11 make rotating motion without doing linear motion up and down, due to rising
Falling tone section screw rod 11 is to be threadedly coupled with scraper lifting shaft 12, what lift adjustment screw rod 11 was fixed in position again, therefore screw thread connects
