Description
Technical field
The present invention relates to a kind of wallpaper printing detent mechanism.
Background technology
Wallpaper, also referred to as wallpaper, English is wallcoverings or Wallpaper, and it is a kind of application indoor hardware fitting quite widely.Because it is various that wallpaper has color, pattern enriches, the feature that other house decorative material multiple such as luxurious style, safety and environmental protection, easy construction, affordable is incomparable, therefore obtains the universal of certain degree at the developed countries and regions such as American-European, Japanese.Wallpaper is divided into a lot of class, as overlay film wallpaper, coating wallpaper, embossing wallpaper etc.Usually produce body paper with bleached wood pulp, then through the processing process of different operation, cover as coating, printing, embossing or surface and mould, dispatch from the factory after cutting, packing.Because have certain intensity, toughness, appearance attractive in appearance and good water repelling property, be widely used in the interior decoration etc. in house, office, hotel, hotel.
Before paper enters printing equipment printing, it is carried out to the location of vertical and horizontal both direction, thus ensure printed sheet and printed sheet, between look and look chromatography accurate.Front lay is the paper stopping part part that paper is accurately located at leading edge edge.How putting forward the accuracy of detent mechanism, is the problem that one of ordinary skill in the art are devoted to solve.
Summary of the invention
The invention is intended to provide a kind of wallpaper printing detent mechanism, to improve the accuracy of work.
Wallpaper printing detent mechanism in this programme, comprise frame, frame is provided with paper passing platform, the side of paper passing platform is provided with front gauge bar, frame is provided with rotary cylinder, the output shaft of rotary cylinder is connected with the first cam and the second cam, the curved surface of the first roller and the first cam that the first rocking bar rotate connection offsets, frame is provided with orders about the resetting means that the first roller is close to the first cam, the driven end of the first rocking bar is hinged by the drive end of connecting rod and front gauge bar, the stage casing of the second rocking bar is hinged in frame, the drive end of the second rocking bar is provided with the second roller and offsets with the second cam, frame is provided with orders about the resetting means that the second roller is close to the second cam, the driven end of the second rocking bar is hinged on the stage casing of front gauge bar.
First rocking bar shakes at left and right directions, the above-below direction shake of the second rocking bar, the oscillation center of front lay is positioned at the below of transfer gripper platform, when paper is about to arrive defeated cardboard leading edge, front lay is put paper is positioned, front straightedge and paper-pressing tongue under turn over while sink, speed away transfer gripper transfer route, prevent paper-tear picture, and don't the correspondent section making cam profile curve is too steep, so that pressure angle is excessive and cause vibration; When front lay being turned over preparation splicing, front lay is lifting slightly, and making has comparatively wide arc gap between front lay paper-pressing tongue and paper passing platform, be convenient to paper prosopyle enter, then front lay is sunk slightly, makes paper-pressing tongue by a small pressing action, paper prosopyle is convinced, is conducive to the accuracy improving location.
Further, described resetting means is spring.
Further, the upper end that front gauge bar is driven is provided with front lay.
Further, the spring the first rocking bar and the second rocking bar connected is arranged in level with vertically respectively.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: the first cam 1, second cam 2, first roller 3, second roller 4, first rocking bar 5, connecting rod 6, second rocking bar 7, front gauge bar 8, front lay 9, the scraps of paper 10, paper passing platform 11, spring 12.
Embodiment is substantially as shown in Figure 1: the left in frame is provided with paper passing platform, the left side side of paper passing platform is provided with front gauge bar, the upper top of front gauge bar is provided with the front lay for locating, in frame, the right of paper passing platform is provided with rotary cylinder, the output shaft of rotary cylinder, perpendicular to drawing place plane, the output shaft of rotary cylinder is connected with the first coaxial and parallel cam and the second cam.
First rocking bar and the first roller are positioned at the right of cam, the curved surface of the first roller and the first cam that the first rocking bar rotate connection offsets, what frame was provided with basic horizontal orders about the spring that the first roller is close to the first cam, the driven end of the first rocking bar is hinged by the drive end of connecting rod and front gauge bar, and namely the rotation of the first cam drives front gauge bar left and right directions to shake.
The stage casing of the second rocking bar is hinged in frame, the second roller on it is positioned at the below of cam, second roller and offseting with the curved surface below the second cam, frame is provided with roughly vertical orders about the spring that the second roller is close to the second cam, and the driven end of the second rocking bar is hinged on the stage casing of front gauge bar.Before the rotating drive of the second cam, gauge bar moves at above-below direction.
The oscillation center of front lay is positioned at the below of transfer gripper platform, when paper is about to arrive defeated cardboard leading edge, front lay is put and carries out longitudinal register to paper; When transfer gripper bites paper, the front lay bottom is by paper.The motion of front lay is by two cover cam link-swing-bar mechanism co-controllings, specific works process is as follows: cam hooks speed and rotates, up and down reciprocatingly swung by roller, fork and connecting rod, drive front lay, in realization pendulum to transfer gripper platform (preparation splicing), on stop (weakening), steady paper, the bottom (allow paper), under stop (waiting for that paper passes through) level Four technological action; Cam makes front lay move up and down with connecting rod by roller, fork and connecting rod.So front lay moves up and down (transport motion) on the one hand, doing again upset on the other hand and swing (relative motion), is namely the compound motion of these two kinds motions.The results of such two motion synthesis, can make front straightedge and paper-pressing tongue under turn over while sink, speed away transfer gripper transfer route, prevents paper-tear picture, and don't make the correspondent section of cam profile curve too steep, so that pressure angle is excessive and cause vibration; When front lay being turned over preparation splicing, front lay is lifting slightly, and making has comparatively wide arc gap between front lay paper-pressing tongue and paper passing platform, be convenient to paper prosopyle enter, then front lay is sunk slightly, makes paper-pressing tongue by a small pressing action, paper prosopyle is convinced, is conducive to the accuracy improving location.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
