Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1:

referring to fig. 1-6, the present invention provides an embodiment: platen axle is pressed to frame for printer, including printer frame 1, draw-in groove 2, press platen shaft 3 and spacing fixture block 4, draw-in groove 2 is seted up inside the rear end of printer frame 1, press platen shaft 3 movable mounting in the inside of draw-in groove 2, the equal fixed mounting in both sides end of printer frame 1 has installation card axle 6, it has torsional spring 5 to rotate the joint on installation card axle 6, the equal fixed mounting in both sides end of printer frame 1 separates baffle 7, and separate baffle 7 and be located top one side of installation card axle 6, and press the inside at torsional spring 5 of both ends joint of platen shaft 3, can carry on spacingly and press to the paper of carrying in by printer frame 1 through setting up platen shaft 3, make the paper be located inside the bottom of platen shaft 3 all the time, and the tension in the paper transportation process can utilize torsional spring 5 to cushion adjustment.

There is the clearance between the outer wall of pressing the paper axle 3 and the draw-in groove 2 for press the paper axle 3 and can carry out the spacing regulation of pressing of continuous change formula adaptation according to the change of paper tension in the inside activity of draw-in groove 2.

The one end that installation card axle 6 was kept away from to torsional spring 5 is the U type setting, and presses the paper axle 3 the end joint to be the partial inside that the U type set up on torsional spring 5 for press paper axle 3 to make torsional spring 5 rotate when the inside of draw-in groove 2 removes and play the effect of cushion adjustment.

The baffle 7 separates the fender to the spacing one end of torsional spring 5 in the torsional spring 5 rotation process, and pivoted torsional spring 5 plays the effect to 3 position limit adjustment on pressing the paper axle to indirect effect that play cushioning modulation when paper tension changes, and separate the baffle 7 and can separate the fender to torsional spring 5, prevent that torsional spring 5 pivoted angle is too big.

Example 2:

on the basis of embodiment 1, as shown in fig. 7, the outer wall of the paper pressing shaft 3 is uniformly and fixedly provided with a fixed clamping seat 9, the inside of the fixed clamping seat 9 is uniformly and fixedly provided with an electric hydraulic push rod 10, the upper end of the electric hydraulic push rod 10 is fixedly provided with a telescopic pressing sheet 8, the telescopic pressing sheet 8 is provided with six telescopic pressing sheets 8, the telescopic pressing sheets 8 are arranged in an arc shape, and the outer surface of the telescopic pressing sheet 8 is smoothly arranged.

The even fixed mounting of outside through pressing the paper axle 3 has electric hydraulic rod 10, and electric hydraulic rod 10's front end outside fixed mounting has flexible preforming 8, carry out synchronous flexible can make the synchronous shrink of each flexible preforming 8 or expand outward through controlling each electric hydraulic rod 10 at the in-process that uses the paper axle 3, thereby make the holistic diameter of pressing paper axle 3 and flexible preforming 8 constitution can adjust and control, thereby can carry out the processing of spacing and the pressure of different degrees to the paper of passing through by pressing paper axle 3 and flexible preforming 8 bottom according to the needs that use.

The working principle is as follows: the printer can be carried in printer frame 1 after the paper passes through the support of spacing fixture block 4 spacing at the in-process of work, it is spacing and press to utilize the paper pressing axle 3 to carry out the paper in the in-process of carrying, when the paper changes in the in-process of carrying, can make torsional spring 5 rotate through the paper pressing axle 3, because the end joint of paper pressing axle 3 is inside the part that the U type set up on torsional spring 5, consequently, can make torsional spring 5 rotate, thereby pivoted torsional spring 5 utilizes the inside removal of paper pressing axle 3 at draw-in groove 2 to play the effect to paper tension buffering and regulation, and torsional spring 5 rotates the spacing fender of one end of torsional spring 5 of in-process mesophragma baffle 7, consequently, make the paper be located inside the bottom of paper pressing axle 3 all the time in the process of carrying, carry out spacing continuous stable transport of pressing by paper pressing axle 3.

Make the synchronous completion shrink of each flexible preforming 8 through synchronous each electronic hydraulic push rod 10 of start-up at the in-process of paper transport, can adjust the diameter that changes the holistic last item that presses paper axle 3 and flexible preforming 8 and constitute, consequently can make things convenient for quick regulation control to the degree of pressing down spacing fender of paper at the in-process of paper transport for the paper is carried by steady transmission between printer frame 1 and the spacing fixture block 4, the utility model discloses can carry out spacing pressing to printing paper in the use, can carry out automatic buffering regulation to the tension that produces in the paper transportation process, makes the paper be located the inside steady transport in bottom of pressing paper axle 3 all the time.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
