A kind of paper fixing device of printing machine
Technical field
The present invention relates to a kind of printer part, particularly a kind of paper fixing device of printing machine.
Background technology
With the continuous development of society with progress, also constantly expanding for the demand of print product, this promotes print
The continuous progress of brush technology.In order to meet the speed of printing, technical staff selects roll web rather than cut good paper, this
Sample can cause printing to be carried out continuously, and improve efficiency, but existing reel paper material is in printing process, itself is to turn
It is dynamic, it is necessary to be pulled by external force so that it is rotated, such words paper be in tension state for a long time, easily sends out
Raw fracture, printing will be interrupted, and reduce the efficiency of printing;Meanwhile the requirement printed to paper is very high, if paper be subject to compared with
Big pulling force, even if paper is not broken, can also influence the quality of printing.In addition, the installation of the roll shaft equipped with paper is with tearing open
Unload and more bother, have impact on the efficiency of printing.Therefore, the efficiency that existing technology is easily broken there is paper, prints
The problems such as susceptible, undesirable roll shaft installing and dismounting difficulty and printing quality equipped with paper.
The content of the invention
It is an object of the present invention to provide a kind of paper fixing device of printing machine.It has paper it is not easy to break, improve
The efficiency of printing, easy disassembly roll shaft and the characteristics of improve printing quality.
Technical scheme:A kind of paper fixing device of printing machine, including base, base both ends, which are equipped with, tilts cloth
The stent put, the both ends of internal stent are equipped with the dragging track being in tilted layout, and dragging track is equipped with hydraulic stem, hydraulic rod end
Support base equipped with U-shaped structure, support base are equipped with roll shaft;Supporting rod, post upper portion are equipped between the dragging track
Lower retainer ring equipped with semi-circular structure, is equipped with above lower retainer ring and the corresponding upper retainer ring of lower retainer ring, and upper retainer ring
End is equipped with hydraulic telescopic rod, and hydraulic telescopic rod and the inner wall of cradle top are mutually fixed;The inner side of the dragging track is equipped with big
Gear, the roll shaft are equipped with the pinion gear being meshed with gear wheel.
In a kind of paper fixing device of foregoing printing machine, the lower face of fixed ring is equipped with the first magnet,
The upper surface of lower retainer ring is equipped with the second magnet, and the first magnet and the second magnet are attracting.
In a kind of paper fixing device of foregoing printing machine, the first of multiple rubber material are equipped with fixed ring
Roller, is equipped with the first spring between the first roller and upper retainer ring;The second of multiple rubber material are equipped with the lower retainer ring
Roller, is equipped with second spring between the second roller and lower retainer ring.
In a kind of paper fixing device of foregoing printing machine, the supporting rod lower end is equipped with buffing pad, buffing pad and bottom
Seat is connected.
In a kind of paper fixing device of foregoing printing machine, the stent lower part is equipped with opening, and stent outer wall is equipped with
For the shifting chute of roll shaft movement.
Compared with prior art, the present invention is intermeshing large and small by being set on the inner side of dragging track and roll shaft
Gear, and rotated by transmission shaft so that fixed rotating shaft itself can provide the power of paper rotation, it is not necessary to by external force
To drive, such paper would not be subject to very big pulling force, so as to reduce the possibility of paper break, improve the effect of printing
Rate, while paper does not stress, its internal structure will not occur to change accordingly, so as to improve the quality of printing;Work as roll shaft
After departing from dragging track, roll shaft is fixed by upper and lower retainer ring, facilitates the dismounting of roll shaft, in addition, in upper and lower fixation
Magnet is set on ring, makes its fixed effect more preferable, while roller is installed in upper and lower retainer ring, and can by spring
Roller while stationary roller shaft, will not roll shaft rotation impact.In addition, two pinion gears set on roll shaft are also right
Spacing effect is played in the installation of roll shaft, facilitates its installation.In conclusion the present invention has, paper is not easy to break, improves printing
Efficiency, easy disassembly roll shaft and improve printing quality the characteristics of.

Embodiment
The invention will be further described with reference to the accompanying drawings and examples, but not as the foundation limited the present invention.
Embodiment.A kind of paper fixing device of printing machine, is formed as shown in Figure 1, Figure 2, Figure 3 and Figure 4, including base 1,
1 both ends of base are equipped with the stent 2 that is in tilted layout, and the both ends inside stent 2 are equipped with the dragging track 3 being in tilted layout, dragging track 3
Hydraulic stem 4 is equipped with, 4 end of hydraulic stem is equipped with the support base 5 of U-shaped structure, and support base 5 is equipped with roll shaft 6;The dragging track
Be equipped with supporting rod 7 between 3,7 upper end of supporting rod is equipped with the lower retainer ring 8 of semi-circular structure, the lower top of retainer ring 8 be equipped with it is lower solid
Determine the corresponding upper retainer ring 9 of ring 8, and 9 end of upper retainer ring is equipped with hydraulic telescopic rod 10, hydraulic telescopic rod 10 is pushed up with stent 2
