Description

The trimming mechanism of roll printing system

Technical field

This utility model relates to printing technology, particularly relates to the trimming mechanism of a kind of roll printing system.

Background technology

In existing paper printing technology, generally use offset printing, but inefficient average the 2.5 ten thousand of offset printing Part/hour, the raising required printing efficiency along with people, this production efficiency is the most no longer printed industry and is promoted, therefore The applicant have devised a kind of roll printing system, is suitable for the printing of high-volume paper at a high speed, and speed is fast, average 40,000 parts/little Time.But in actual applications, there is the phenomenon of paper sideslip in occasional, for the occasion higher to paper required precision, as needed If paper is identified by optical character reader (OCR) to be passed through, if just cannot be correct when the margin of paper is too many recognize Information on paper.Therefore the applicant have developed a kind of automatically paper to sideslip and carries out the mechanism of deburring, every to ensure The margin width opening paper is consistent.

Utility model content

This utility model is intended to provide the trimming mechanism of a kind of roll printing system, with reach the paper to sideslip carry out from The purpose of dynamic deburring.

For reaching above-mentioned purpose, base case of the present utility model is as follows: the trimming mechanism of roll printing system, including machine Frame, also include that monitor control mechanism, undercut mechanism and shearing tool, described monitor control mechanism include that rack-mounted signal is launched Device, signal receiver and controller, described undercut mechanism includes two clamping limbs being hinged, and connecting between two clamping limbs has Elastic component, the free end of two clamping limbs is provided with the grip block of irony, is wherein provided with electric magnet, described electromagnetism in a grip block Ferrum is electrically connected with controller；Described shearing tool is in the shape of the letter V.

The principle of this programme is: when monitor control mechanism detects that paper offset by the formulation of normal route during transmitting During scope, monitor control mechanism passes the signal in controller, so that controller controls undercut mechanism and shearing tool simultaneously, stings The electric magnet energising band magnetic of a limit mechanism wherein grip block, and adsorb another grip block, paper clamp is handled.Reciprocator simultaneously Promote the second blade, paper is sheared.

The advantage of this programme is: the real-time monitoring during 1, being transmitted paper by monitor control mechanism, and passes through undercut The paper edge crossed the border is cut off by mechanism and shearing tool, thus ensures every the paper margin width one printed Cause, in order under special occasions, the optical character reader (OCR) identification to paper information.2, during pruning, simultaneously by stinging Paper edge is bitten by limit mechanism, is laterally strained by paper so that the shearing tool pruning to paper, to avoid paper edge Produce buckling phenomena.3, by shearing tool setting is in the shape of the letter V, on the one hand paper is played guide effect, paper is imported V The center angular position of the shearing tool of font, it is to avoid paper stirs during pruning up or down, is difficult to prune.

Preferred version 1: based on the improvement of scheme, described shearing tool includes the first blade and the second blade, described First blade is fixed in frame, and the second blade is hinged on the middle part of the first blade, between described first blade and the second blade Being provided with spring, described second blade connects has the reciprocator for promoting the second blade rotation, by above-mentioned setting, when treating When the paper of deburring is sent between the first blade and the second blade, reciprocator's intermittent promotion the second blade, make shearing Paper is cut and is opened a gap by cutter, thus is quickly fallen by unwanted Partial Shear.

Preferred version 2: the preferably improvement of 1, by entering the activate switch of described controller with reciprocator Row is electrically connected, and only when monitor control mechanism detects that paper needs deburring, controller just controls reciprocator's action, to avoid shearing Mechanism one direct acting and cause the wasting of resources.

Preferred version 3: based on scheme or the improvement of preferred version 2, in order to strengthen the clamping to paper of the undercut mechanism Power, spy is provided with projection, to avoid the occurrence of skidding on the surface of described grip block.

Accompanying drawing explanation

Fig. 1 is the structural representation of the trimming mechanism embodiment of this utility model roll printing system.

Fig. 2 is the side view of the trimming mechanism of this utility model roll printing system.

Detailed description of the invention

Below by detailed description of the invention, this utility model is described in further detail:

Reference in Figure of description includes: signal projector 1, signal receiver 2, clamping limb 3, stage clip 4, clamping Block 5, electric magnet the 6, first blade the 7, second blade 8, reciprocator 9, paper 10.

Embodiment is the most as shown in Figure 1: the trimming mechanism of roll printing system, including frame, also include monitor control mechanism, Undercut mechanism and shearing tool, cutting mechanism is arranged on undercut mechanism and monitor control mechanism includes rack-mounted and mutual The signal projector 1 of Electricity Federation, signal receiver 2 and controller, what signal projector 1, signal receiver 2 were respectively adopted is infrared Emitter and infrared remote receiver, holding wire distance paper 10 edge that signal projector 1 sends is less than 0.01mm.Undercut mechanism of place Including two clamping limbs being hinged 3, connect between two clamping limbs 3 and have stage clip 4, be that two clamping limbs 3 are under normal conditions Open state, the free end of two clamping limbs 3 is provided with the grip block 5 of irony, and the surface of grip block 5 is provided with projection, wherein a folder Being provided with electric magnet 6 in holding block 5, electric magnet 6 is electrically connected with controller.

As in figure 2 it is shown, shearing tool is in the shape of the letter V, shearing tool includes the first blade 7 and the second blade 8, the first blade 7 Being fixed in frame, the second blade 8 is hinged on the middle part of the first blade 7, is provided with spring between the first blade 7 and the second blade 8, Connecting the reciprocator 9 having for promoting the second blade 8 to rotate on second blade 8, the activate switch of reciprocator 9 passes through wire Connecting on the controller, this reciprocator 9 can use cylinder or cam mechanism.When monitor control mechanism detects that paper 10 needs deburring Time, controller just controls reciprocator 9 action, reciprocator 9 intermittent promotion the second blade 8, makes shearing tool by paper 10 cut and open a gap, thus are quickly fallen by unwanted Partial Shear.

In actual applications, when paper 10 offset by the formulation scope of normal route during transmitting, infrared emission The signal that device sends will be blocked by paper 10, cause infrared remote receiver cannot receive signal, so that controller controls to sting Limit mechanism and shearing tool, the electric magnet 6 of a undercut mechanism wherein grip block 5 is energized band magnetic, and adsorbs another grip block 5, will Paper 10 clamps.Reciprocator 9 promotes the second blade 8 simultaneously, shears paper 10.

Above-described is only embodiment of the present utility model, the known general knowledge such as concrete structure and/or characteristic in scheme Too much describe at this.It should be pointed out that, for a person skilled in the art, before conceiving without departing from this utility model Putting, it is also possible to make some deformation and improvement, these also should be considered as protection domain of the present utility model, and these are all without shadow Ring effect and practical applicability that this utility model is implemented.The protection domain that this application claims should be with in its claim Appearance is as the criterion, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
