Abstract

The utility model relates to satellite type flexographic printing machine comprising a pair of center printing rollers. A plurality of version rollers are arranged around the center printing rollers. The diameter of each center printing roller is equal to the integer times of the diameter of each version roller. Each version roller is pasted with a printing rubber plate. Each center printing roller is pasted with one or more pieces of printing rubber plates. Rotary printing rubber plates are particially covered or completely covered on the surfaces of the printing rollers corresponding to the circle core in a central symmetry way. When the number of rotary printing rubber plates is more than one, the printing length and the printing width of each rotary printing rubber plate are same. All the printing rubber plates are evenly distributed on the circumferences of surfaces of the center printing roller looking from the transversal section. The utility model effectively increases the printing rate and makes full use of the equipment resource of the complete printing machine.

Description

Satellite-type flexible printing machine

Technical field

The utility model relates to a kind of printing machinery, is specifically related to a kind of satellite-type flexible printing machine.

Background technology

Satellite-type flexible printing machine can keep accurate aligning for the printed patterns of koan roller in making and version roller always, and the diameter of middle koan roller must be the integer multiple of edition roller diameter, is generally twice or three times.On the middle koan roller of existing satellite-type flexible printing machine the monolithic transfer blanket only is set all, and the spreading width of transfer blanket must be equal to or less than an edition roller girth, because the middle koan roller diameter of existing satellite-type flexible printing machine is more than two times of edition roller diameter, therefore in the middle koan roller revolution stroke in a moving week, have only the time or the stroke of less than 1/2nd to print, middle koan roller revolution is moving a week only finishes one-step print, China utility model patent ZL03223226.8 discloses a kind of middle koan roller of printing machine, the i.e. described printing rubber roller of this patent, this printing rubber roller surface is provided with two axial inner groovies and is used to compress rubber, it is topped that rubber is only made part to printing rubber roller (middle koan roller) surface, fully showed prior art cause in the backlash of koan roller more than 1/2nd, be unfavorable for improving defectives such as printing efficiency and speed.

Summary of the invention

The purpose of this utility model is that a kind of satellite-type flexible printing machine will be provided, and it is by effective print stroke of increase transfer blanket koan roller in the lip-deep cover ratio of middle koan roller improves, thus the purpose of raising print speed printing speed.

The purpose of this utility model is to realize like this, satellite-type flexible printing machine described in the utility model comprises a pair of middle koan roller 1, around the middle koan roller some version rollers 3 are installed, the diameter of middle koan roller equals the integer multiple of edition roller diameter, post printing blanket on the every version roller, post a slice or the above transfer blanket 4 of a slice on the every middle koan roller, transfer blanket is centrosymmetric with respect to the center of circle and does local or all cover on middle koan roller surface; When transfer blanket is a slice when above, the length and the width of each sheet transfer blanket are identical, from the cross section, during the position of each sheet transfer blanket is evenly distributed on the circumference on koan roller surface.

The diameter of middle koan roller is the twice of version roller diameter, posts two transfer blanket on the every middle koan roller, and the position of two transfer blanket is centrosymmetric with respect to the center of circle of middle koan roller.

The diameter of middle koan roller is three times of version roller diameter, posts three transfer blanket on the every middle koan roller, and the position of three transfer blanket is centrosymmetric with respect to the center of circle of middle koan roller.

Each printing blanket is fitted by Double-face gummed paper and each edition roller respectively.

Each transfer blanket is fitted by Double-face gummed paper and middle koan roller respectively.

The utlity model has following advantage and effect:

Owing to can local or all cover transfer blanket on the middle koan roller surface, and in the process in a moving week of middle koan roller revolution, the version roller makes each sheet transfer blanket all stamp same pattern, each sheet transfer blanket just successively is transferred to printed patterns on the printing element 2, koan roller revolution is moving in being equivalent to can print several times once week, the time or the effective travel that promptly are used to print are multiplied, thereby the print speed printing speed of significantly improving makes full use of the device resource of whole printing machinery.

The utility model will be further described below in conjunction with drawings and Examples.

The specific embodiment

Embodiment 1: as Fig. 1, shown in Figure 2, the utility model embodiment 1 described satellite-type flexible printing machine is provided with two middle koan rollers 1 up and down, can carry out front-back two-sided printing to printing element 2 simultaneously, koan roller 1 periphery is equipped with four version rollers 3 in each, the diameter of middle koan roller 1 equals the twice of edition roller 3 diameters, post two transfer blanket 4 on the every middle koan roller, as shown in Figure 2, from the cross section, two transfer blanket 4 are attached on the middle koan roller surface, formed radian measure alpha size is identical, therefore the arc length (being equivalent to printing length) of two transfer blanket 4 formation is identical, the position of two transfer blanket 4 is evenly distributed on the circumference on middle koan roller 1 surface, promptly the phase angle β size that separates of two transfer blanket, 4 head and the tail is identical, and α and β addition just equal 180 degree.

Among the utility model embodiment 1, printing blanket is fitted by Double-face gummed paper and corresponding version roller; Transfer blanket is fitted by Double-face gummed paper and middle koan roller.

Embodiment 2: as shown in Figure 3, Figure 4, in the utility model embodiment 2, the diameter of middle koan roller 1 equals three times of edition roller 3, post three transfer blanket 4 on the every middle koan roller 1, as shown in Figure 4, from the cross section, during three transfer blanket 4 are attached on the koan roller 1 the radian measure alpha size that forms identical, they are evenly distributed on the circumference of middle koan roller 1, the phase angle β size that promptly every adjacent two transfer blanket, 4 head and the tail separate is identical, α and β addition just equal 120 degree, and all the other conditions are identical with embodiment 1.

Certainly, in other embodiment of the utility model, the quantity of transfer printing hectograph also can be a slice or four, five even multi-disc more, and middle koan roller diameter also should corresponding the adjustment with the ratio of version roller diameter.These embodiment fall into protection domain of the present utility model.
