Abstract
The utility model relates to a paper feeding roller clamping mechanism which comprises lower paper feeding rollers and upper press rollers. The lower paper feeding rollers and the upper press rollers are arranged on a rack. Two ends of each upper press roller are connected with a roller shaft sleeve. The upper end of any roller shaft sleeve is connected with an elastic piece. The upper end of each elastic piece is connected with a press regulating plate, and a press regulating device enabling the press regulating plate to push or ascend is arranged on the press regulating plate. Due to the fact that the press regulating plate is pushed or ascended through the press regulating device, expansion amount of the elastic piece is regulated to exert different pre-tightening force on the roller shaft sleeves, the horizontal paper pressing state of the press regulating plates can be sustained even paper sheets different in width and thickness are processed, paper pressing effect is improved, and wide application range is achieved. The paper feeding roller clamping mechanism can be applied to a paper processor.

The specific embodiment
As shown in Fig. 3-Fig. 7, defeated paper rubber roll clamping mechanism, comprises the lower feed rollers 2 and the upper pressure roller 3 that are arranged in frame 1.The two ends of lower feed rollers 2 are directly positioned in frame 1, and the two ends of upper pressure roller 3 are connected to roll sleeve 4, and the bearing of pressure roller 3 is housed in roll sleeve 4.Position with respect to roll sleeve 4 in frame 1 offers side channel, forms and to make roll sleeve 4 mobile space vertically in frame 1.The upper end of roll sleeve 4 is connected to pressure spring 6, and the integral body of pressure spring 6 is positioned at side channel, and its upper end is fixed on the top of side channel, makes pressure spring 6 pair roller axle sleeves 4 produce certain pressure.
Shown in Fig. 3,4,5,6, in figure, the upper end of pressure spring 6 is also connected to regulator board 5, on regulator board 5, be provided with the regulator that makes regulator board 5 press down or rise, when regulator board 5 presses down, thereby pressure spring 6 pair roller axle sleeves 4 produce larger pressure to one end of upper pressure roller 3, when paper passes through from a side of close regulator between two rollers, cannot produce the external force that makes pressure roller 3 one end perks, the level of pressure roller 3 in maintenance, has guaranteed the effect of platen.
Preferably, in frame 1, be fixed with pressure regulation support 9.Regulator comprises the longitudinal slide 7 being bolted on regulator board 5, longitudinal slide 7 is provided with longitudinal chute 71, be arranged on pressure regulation support 9 with the slide block 8 of longitudinal chute 71 bearing fits, the upper end of longitudinal slide 7 is provided with and compresses unit, by compressing unit, compress contact longitudinal slide 7, make longitudinal slide 7 drive regulator board 5 to slidably reciprocate up and down along chute direction.
Preferably, as shown in Fig. 4 and Fig. 7, compress unit and comprise rotatable eccentric wheel 10, eccentric wheel 10 be arranged at longitudinal slide 7 directly over, its rotating shaft one end is connected in frame 1, the other end is connected on the bracing frame 15 fixing with frame 1.Eccentric wheel 10 surfaces compress face for compressing the arc on longitudinal slide 7 tops.As shown in Figure 3 and Figure 4, when eccentric wheel 10 clickwise, its arc compresses face continues longitudinal slide 7 to press down.The inner side of eccentric wheel 10 is leaned on mutually but is not contacted with frame 1, and the outside of eccentric wheel 10 is also connected with the operation fork 11 through bracing frame.
