Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1-3, the present utility model provides a technical solution: a tension control structure of a high-speed printer comprises a bottom plate 1, a tension adjusting roller 8 and two tension buffer mechanisms;
the upper surface of the bottom plate 1 is vertically and fixedly connected with two electric control telescopic rods 2, and two tension buffer mechanisms are respectively arranged at the top ends of the two electric control telescopic rods 2;
two tension buffer gear structures are the same, and one of them tension buffer gear includes vertical fixed connection in the erection column 3 on an automatically controlled telescopic link 2 top, and spout 4 has been vertically seted up on the top of erection column 3, and the inside of spout 4 is followed its length direction sliding connection and is had mounting disc 5, and the upper portion threaded connection of erection column 3 surface has installation sleeve 10, and the top fixedly connected with upper cover 12 of installation sleeve 10, the bottom rotation of upper cover 12 is connected with rotating block 13, fixedly connected with extension spring 14 between rotating block 13 and the mounting disc 5.
The surface of the opposite side of the two mounting columns 3 is provided with sliding holes 6 along the length direction, a mounting shaft 7 is fixedly connected between the two mounting plates 5 through the two sliding holes 6, and a tension adjusting roller 8 is rotatably connected to the surface of the mounting shaft 7.
