Description

A kind of printing machine paper feeding tension structure

Technical field

The utility model relates to a kind of tension structures, need especially suitable for intermittent roll web when printing machine works normally Use when paper rear is refunded.

Background technique

Intermittent roll web during printing machine normal printing work, it is every printed a frame printed patterns after, need to be paper Opposite direction is refunded, and paper intermittent feeding is made, to guarantee that white space is required length between each frame pattern, paper sky does not occur White region is excessive and causes paper waste, when paper is reversely refunded, due to the charging of conveyer continuous uniform always, in this way It will cause the relaxation of paper and influence the quality of subsequent printing, how to allow not relax when paper feeding when developing printing machine work be this The target of technical field personnel sustained improvement and innovation.

Summary of the invention

The task of the utility model is to propose that a kind of paper of relaxation is tightened up, and improves printing efficiency, guarantees print quality A kind of printing machine paper feeding tension structure.

The task of the utility model be done in such a way that it is characterized by: the technical program include preceding conveyer, it is rear defeated Paper device, conveyer, the conveyer are mounted in the centre of forward and backward conveyer, and the side of interval feed rollers Dancing roll C2, dancing roll C1, dancing roll A3, the dancing roll A1 being arranged on the conveyer are arranged in sequence on following wallboard It spaces out with dancing roll A2 and is fixed on the wallboard of conveyer up and down, the dancing roll A2 and dancing roll A3 is to be arranged in parallel Wallboard between and there are distance respectively with conveyer and rear conveyer is fixed, and linear motor is fixed on conveyer On wallboard, the sliding panel of the linear motor is connect with connecting plate, and another face of slide plate and storing roller, another storing roller I connection.It is fixed with feed rollers on the wallboard of the preceding conveyer, is fixed with interval paper feeding on the wallboard of the rear conveyer Roller.Linear motor work, drives connecting plate as linear motor makees horizontal reciprocating movement, and drive storing roller and another storing I horizontal reciprocating movement of roller.

The utility model has the following effects that mechanism realizes that paper is tensioned by the reciprocating horizontal motion of linear motor Function, linear motor runs smoothly, and the speed of service is fast, can easily be controlled, and can effectively improve the efficiency of printing, protects The quality of printing is demonstrate,proved.

Detailed description of the invention

Drawing explanation: conveyer, 201. feed rollers, 300. conveyers, 301. dancing roll A1,302. before 200. Linear motor, 303. dancing roll A2,304. storing rollers, 305. connecting plates, 306 I, another storing roller, 307. dancing rolls Conveyer, 401. interval feed rollers behind A3,308. dancing roll C1,309. dancing roll C2,400..

Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model Limitation.

Specific embodiment is as depicted in figs. 1 and 2, and the technical program includes preceding conveyer 200, rear conveyer 400, defeated Paper device 300, the conveyer are mounted in the centre of forward and backward conveyer, fix on the wallboard of the preceding conveyer There is feed rollers, is fixed with interval feed rollers 401 on the wallboard of the rear conveyer 400, and under the side of interval feed rollers It is arranged in sequence with dancing roll 309C2, dancing roll 308C1, dancing roll 307A3 on the wallboard in face, is arranged on the conveyer 300 Dancing roll A1 and dancing roll A2 space out and be fixed on the wallboard of conveyer up and down, the dancing roll 303A2 with lead paper Roller A3 be arranged in parallel and also between there are wallboard of the distance respectively with conveyer and rear conveyer to fix.Linear motor 302 are fixed on the wallboard of conveyer, and the sliding panel of the linear motor is connect with connecting plate 305, and slide plate another Face is connect with storing roller 304, another storing roller 306 I, (as shown in Figure 2).Linear motor work, drive connecting plate 305 with Linear motor makees horizontal reciprocating movement, and drives storing roller 304 and another 306 I horizontal reciprocating movement of storing roller.

The preceding conveyer includes feed rollers 201；The conveyer includes dancing roll 301A1, dancing roll A2, straight line Motor 302, storing roller 304, another storing roller 306 I, connecting plate 305；Conveyer 400 includes interval feed rollers after described 401, dancing roll 309, dancing roll 308C1, dancing roll 307A3.

This tension structure work when, roll web continuously from preceding conveyer 200 feed, by feed rollers 201 to Preceding paper feeding, feed rollers 201 are always uniform speed rotation according to the direction of rotation in Fig. 1, drive paper at the uniform velocity to advance, by leading Paper bowl A1, dancing roll A2, dancing roll A3, paper enter in mechanism centre tensioning apparatus.At this point, if host process color Group prints a frame pattern, and when needing reversely to refund, the interval feed rollers 401 for being mounted on rear conveyer 400 is reversely rotated, i.e., It is reversely rotated counterclockwise in Fig. 1, the paper for the operation that makes to go ahead relaxes.At this moment, linear motor 302 receives paper relaxation Signal after, start the linear motion done in horizontal direction of turning left, to drive connecting plate 305 and storing roller 304, storing roller 306 move downward.Since dancing roll A3, dancing roll C1, dancing roll C2 are fixedly mounted on rear conveyer 400, store up in this way Expect that roller 304, storing roller 306 and dancing roll A3, dancing roll C1, the route between dancing roll C2 elongate, loose paper is tightened up, To realize the tensioning of paper.If host print couple needs continue to print next frame pattern, it is mounted on rear conveyer 400 interval feed rollers 401 rotates in the forward direction, i.e. reversely rotates clockwise in Fig. 1, and paper Accelerating running, linear motor 302 receives After signal, start the linear motion done in horizontal direction of turning right, drives connecting plate 305 and storing roller 304, storing roller 306 to the right Movement, so that storing roller 304, storing roller 306 and dancing roll A3, dancing roll C1, the route between dancing roll C2 shorten, to meet The needs of continuous printing.

In the utility model unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " fixation " Equal terms shall be understood in a broad sense, for example, it may be fixedly connected, may be a detachable connection or integrally connected, can be two Connection inside a element.For those skilled in the art, above-mentioned term can be understood in this reality as the case may be With novel concrete meaning.
