Abstract
This pinch roller is a friction transported mechanism, particularly by adjusting the clipping gap based on the thickness of the transported articles to keep a constant pressure. Comprised of a passive pinch roller, a compression bar and a spring, it features in the spring length adjusting device included by a cam, linking rod and a rocking rod with the said cam's camber leaning against the compression rod, both ends of the linking rod articulated with one end of the cam and the other of the rocking rod, which rested on the supporting axle of the frame, with the said spring's both ends connect with the other end of the rocking rod and one end of the compression rod. It has solved the technical issue of keeping the constant pressure of the passive pinch roller.
Description
Technical field:
The invention relates to the pressing wheel mechanism of friction transmission, particularly about can be by transported substance thickness adjusted clamping gap to keep the pressing wheel mechanism of constant pressure.
Background technology:
The driving of indoor outer wide format printer and its medium of chopping machine is by means of the friction transmitting device, this friction transmitting device mainly is made of driving wheel and passive pinch roller, passive pinch roller then is arranged on an end of depression bar, apply a pressure by the spring that links to each other with depression bar, and this pressure of mat presses to driving wheel with passive pinch roller, makes the medium transmission forward with the rotation of driving wheel that is clamped between this driving wheel and passive pinch roller.The characteristics of the existing this pressing wheel mechanism of being made up of spring, depression bar and passive pinch roller are that the elastic force of this spring is to change with the distance between passive pinch roller and the driving wheel, distance between passive pinch roller and driving wheel is bigger, and the pressure that spring is applied on the passive pinch roller is bigger.The thickness of medium is thicker in other words, and passive pinch roller is bigger from the distance of driving wheel, and the distortion of spring is bigger, and its spring force is also bigger.For a friction transmitting device that uses special medium, the elastic force of its pressing wheel mechanism (also being thrust) is that the thickness by this special medium comes design-calculated, and is neither tightly also not loose, just in time is fit to the friction transmission requirements.In case the thickness of medium has change, not that appearance " skidding " is exactly the vestige that marks pinch roller on medium, will cause the damage of medium when serious, even can't normal operation.But in fact to different printing projects, the thickness of medium is different, and difference is very big.Therefore, the wheel press mechanism of existing indoor outer wide format printer and chopping machine transmission medium can not satisfy the requirement of transmission different-thickness medium to the restricted requirement of dielectric thickness, and the utmost point need be improved.
Summary of the invention:
The object of the present invention is to provide one to compress the adjustable pressing wheel mechanism of thickness, the pressure that solves passive pinch roller keeps invariable technical matters.
A kind of adjustable pressing wheel mechanism of thickness that compresses comprises passive pinch roller, depression bar and spring, it is characterized in that; Be provided with the spring length adjustment device that comprises cam, connecting rod, rocking bar, the curved surface of this cam is resisted against on the depression bar, these connecting rod two ends are hinged with an end of this cam and rocking bar respectively, the shaft of this rocking bar is shelved on the bolster of frame, and described both ends of the spring is connected with depression bar with the other end of rocking bar respectively.
It is characterized in that: depression bar be provided with this cam curved surface against boss.
The present invention has following beneficial effect:
1, by rotating cam, drivening rod makes rocking bar along the slippage of supporting axial plane, make the deformation length of spring remain unchanged substantially, thereby the pressure that guarantees pinch roller is constant.
2, can make same wide format printer or chopping machine be suitable for the medium of the different-thickness of 0.2mm-6mm, enlarge machine range of use and service item.
3, guarantee that medium transport is normal, and can not produce pinch roller trace seal or damage.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Among the figure:
The 1-driving wheel, 2-medium, the passive pinch roller of 3-, 4-depression bar, 41-fulcrum, 42-boss, 5-cam, 6-spring, 7-bolster, 8-connecting rod, 9-rocking bar, 10-camshaft, 11-frame.
The specific embodiment:
See also shown in Figure 1ly, the present invention comprises passive pinch roller 3, depression bar 4 and spring 6.This depression bar 4 articulates by fulcrum 41 and frame 11, and the one end is provided with passive pinch roller 3, and the other end then links to each other with an end of spring 6.The elastic force of spring 6 makes depression bar 4 around fulcrum 41 spinning rollers and the passive pinch roller 3 at depression bar 4 one end places is pressed to the wheel rim surface of driving wheel 1, and the medium that is transmitted is clamped between driving wheel 1 and the passive pinch roller 3.
Be provided with the spring length adjustment device that comprises cam 5, connecting rod 8 and rocking bar 9, wherein this cam 5 is fixed on the camshaft 10 that is arranged at frame 11; One end of this connecting rod 8 and cam are 5 hinged, the other end is then hinged with an end of rocking bar 9; The shaft of this rocking bar 9 is shelved on bolster 7 surfaces of being fixed in frame 11, and its other end then is connected with the other end of spring 6.The elastic force of spring 6 not only makes passive pinch roller 3 press to driving wheel 1 for this reason, simultaneously the shaft of rocking bar 9 is pressed against on the surface of bolster 7, and the curved surface that makes cam 5 by this spring length adjustment device nearly with depression bar 4 corresponding sites against.For each section curved surface that makes cam 5 can contact closely with depression bar 4, and can carry out self-locking, be provided with boss 42 with cam 5 SURFACES MATCHING usually at the corresponding site of depression bar 4.
When anticlockwise this cam 5 of rotation, cam 5 by boss 42 compressing depression bars 4 around its fulcrum 41 clockwises rotation; Passive pinch roller 3 rotates with depression bar 4 and upwards lifts the surface of leaving driving wheel 1, and 1 distance of passive pinch roller 3 and driving wheel is strengthened, and is current smoothly to adapt to the bigger medium of thickness 2.At the same time, cam 5 makes rocking bar 9 move down along bolster 7 surface tilt by connecting rod 8, this amount of moving down and depression bar 4 are when fulcrum 41 is made above-mentioned clockwise and rotated, the amount of movement of the spring point of connection on it quite or equal substantially, the length that is spring 6 is almost constant, and then the also constant maintenance of the elastic force of spring 6 is constant.So, as long as according to the thick change of medium 2, come spinning roller cam 5 to corresponding position, just can make passive pinch roller 3 with the design-calculated constant pressure medium 2 degrees of tightness moderately are clamped in the surface of driving wheel 1 easily, realization had not only had skidding but also had not had the medium transmission of impression.
