Abstract

The utility model provides a device which can assist a water dampening offset press to automatically clean a water roller. The object of cleaning the water roller is achieved by the axial movement spiral function of a leading screw and the contact pressure of water roller flannelette as well as the decontamination function of washing powder water. A gear reducing motor drives two leading screws to rotate by a gear-shaped belt and a belt pulley at the same time; four aligning water rollers are uniformly arranged around each leading screw; the object of automatic cleaning is achieved by the scraping effect of a leading screw spiral trough edge on the water flannelette. The device which can assist a water dampening offset press to automatically clean a water roller has simple and compact structure and simple, convenient and fast operation.

Description

A kind of servicing unit of automatic cleaning offset press damping roller

Technical field

The utility model relates to a kind of printing machine, and the offset press that is specifically related to a kind of water damping mode cleans the servicing unit that leans on the version damping roller automatically.

Background technology

The operation principle of offset press is to utilize the immiscible principle of ink to carry out the printing printing, so offset press generally all has the water supply ink-feeding device.Way of supplying water has two kinds of forms, and a kind of is alcohol water, utilizes rubber roll that the adhesive attraction of alcohol water is transmitted, and directly supplies with the PS space of a whole page; Another kind is that pure water adds fountain solution, utilizes the water flannelette that the suction-operated of water is passed to the PS space of a whole page with water.There is not the problem of printing ink set-off damping roller in preceding a kind of way of supplying water, and a kind of way of supplying water in back very easily occurs leaning on an edition water flannelette to glue and deposits a large amount of printing ink under the unbalanced situation of ink, thereby the print quality problem occurs.Therefore, clean damping roller on time just become to make one of daily groundwork of water damping offset press.

Single color printing generally has only the 1-2 root by a version damping roller, scrapes to wash after during cleaning damping roller being pulled down to get final product.Flourish and polychrome demand along with printing industry, water damping polychrome machine in use cleans damping roller becomes operator's work of headache the most: damping roller One's name is legion (general minimum all have 8), clean difficulty, need scrape one by one and wash, the cleaning amount is big, the labour intensity height, printing is oversize non-cutting time, and operating efficiency is low.If a kind of auxiliary equipment can be arranged, help the printing operation worker to solve these problems, be exactly the problem that the present technique device is solved.

DY452 is the typical water damping four-color press of the polynary company in Beijing independent development exploitation, in user's use, heavy cleaning damping roller work makes the designer feel more pressure, thus, in conjunction with the concrete structure of this kind type, innovation and creation the automatic rinse water roller arrangement (only limiting to the physical dimension aspect) of the special use of this type.

The operation principle of this device can be common to the offset press of all water dampings, the just variation of physical dimension, and concrete type need dispose parts such as different motor-driven and damping roller cutting ferrule.At present, some printing house has disposed cleaning device voluntarily according to the user demand of oneself, but lacks the excavation of principle and the standardization of product design.

The utility model content

The purpose of this utility model is at polynary DY452 four colour offset press, reduces printing operation worker's labour intensity, and increasing work efficiency is the main purpose of present technique invention.Come if promote, all make the operating efficiency problem of water damping offset press with solving print field.

As shown in Figure 1, the operation principle of the utility model device be utilize leading screw move axially screw action with the pressure that contacts of damping roller flannelette, add the decontamination of washing powder water, finish the purpose of cleaning damping roller

The utility model device can just can dispose the water damping offset press that adapts to various by the local accessory size of design alteration, and the scope of application is more extensive.This device has been configured to polynary DY452 product, and by trying out of shop test and user, cleaning performance is very desirable, and scavenging period shortens greatly, and the ground of the utmost point has improved production efficiency, reaches the cleaning purpose fully.

The specific embodiment

As shown in Figure 2, gear reduction motor 10 is installed in base for supporting 1 bottom, reaches to hide and purpose of safety, and its working speed is consistent with printing machine operate as normal rotating speed, by the transfer function of cog belt 11 and belt wheel 12, drives leading screw 7 and does the effect of turning clockwise.By the pressure that contacts that debugging in advance gets well is arranged between version damping roller 3 and the leading screw 7, during leading screw 7 rotations, the spiral trough rim has an axial scraping effect to the right to the water flannelette, at this moment, water the washing powder water that configures, just can automatically the sticking printing ink of depositing on the water flannelette be washed down.Waste water after the cleaning falls in the drip tray 9, flows in the water receiver 9 by discharge outlet 8.Consider the antiseptic and rustproof problem after leading screw 7 contacts water, leading screw adopts the electroplating processes measure.Electric control system 5 uses the frequency conversion potentiometer, and the low speed starting reaches permanent speed by speed governing then during startup.Design normal wash rotating speed is 60-70 rev/min.

Structure illustrates that as shown in Figure 3 left support arm (6,14) and right support arm (7,13) are contained on the support set 15, are rotatably assorted, and can realize the swing of damping roller wrapping wire thick stick 12 centers.Eccentric bushing 9, cutting ferrule 10 and back shaft 3 are housed on the support arm of the left and right sides, and eccentric bushing 9 is used for realizing adjusting the pressure that contacts of damping roller (5,11) and leading screw 12, and back shaft 3 is used for shelving damping roller bearing 4, and realizes locking with cutting ferrule 10.On (2,8) wallboard, it rotated by synchronous pulley (1) and drives about leading screw 12 leaned on support set 15 and bearing to be connected.

Dig shown in the view as Fig. 4 A-A, two rhizoid thick sticks 4 are set on the support set, evenly arrange 4 around each leading screw by version damping roller 1, and each all is contained in the support cutting ferrule that is fixed on the left and right sides support arm (2,3) by version damping roller two.During cleaning, 8 damping rollers clean simultaneously, have improved cleaning efficiency.

The characteristics of the technical program:

1., simple and compact for structure, the design low processing cost, suitable popular printing house is equipped with;

2., concrete structure adapts with the product that matches, and is simple to operation, quick;

3., by change leading screw and support arm structure size, can dispose the printing machine to any water damping, adaptability is relatively good;

4., the potentiometer speed governing, can realize low rate start, run up, effectively protect equipment
