Description

Printing platform induced drafts

Technical Field

The utility model relates to an ink jet printing technology field, concretely relates to print platform induced drafts.

Background

The digital ink-jet printer comprises a system controller, a board card, a spray head, a printing medium, a printing platform, a driving system and the like. The printing medium is arranged on the printing platform and is at a proper distance from the spray head, and the controller, the board card and other components control the spray head to spray ink on the printing medium. Since the distance between the nozzle and the printing medium is small during printing, the printing medium is required to be flatly attached to the printing platform. When the printing medium is paper, after the ink is sprayed on the printing medium, the paper can swell due to the permeation of the ink, and at the moment, the problems of the paper, such as the rubbing of a spray head, the deformation of a printing pattern, the ghost image and the like can occur. In the prior art, a method for solving the problem is to arrange an air suction hole on the printing platform and use negative pressure to flatly attach paper to the printing platform. The method can solve the problem generated by single-color printing, and when printing in multiple colors such as two-color printing, four-color printing and the like, because the same part of the printing medium is sprayed by ink with different colors, the bulge of the part of paper on the printing platform is increased, and the problem can still be generated. In contrast, the conventional method increases the suction amount to form a larger negative pressure, which causes the paper to be unable to stretch and flatten, and forms sharp protrusions and wrinkles.

In view of this, the utility model provides a print platform induced drafts to the unable effective printing platform that pastes flatly of paper when the polychrome that exists among the solution prior art is printed and scrapes the shower nozzle, prints pattern deformation and the paper technical problem that fold, injustice.

Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Example 1:

referring to fig. 1 and 2, an induced draft printing platform comprises a platform body 1, and the improvement is that: the platform body 1 is provided with a plurality of air suction holes 2 which penetrate through the upper surface and the lower surface of the platform body 1, and the air suction holes 2 are uniformly distributed; the platform body 1 is also provided with a plurality of air suction grooves 3, and the air suction grooves 3 are uniformly arranged along the longitudinal direction of the platform body 1; the left end of platform body 1 is the feed end, the right-hand member is the discharge end, the groove 3 that induced drafts does not link up extremely the feed end of platform body 1, the groove 3 that induced drafts link up extremely the discharge end of platform body 1, the groove 3 that induced drafts is seted up in the upper surface of platform body 1 and does not link up extremely the lower surface of platform body 1, the groove 3 that induced drafts is in the cross-section in a plurality of planes from the left hand right side that platform body 1's upper and lower direction and longitudinal direction formed, left cross sectional area is less than the cross sectional area on right side.

Defining: with the direction shown in fig. 1 as a reference, the front-rear direction is the up-down direction of the platform body 1, the up-down direction is the longitudinal direction of the platform body 1, and the left-right direction is the left-right direction of the platform body 1.

In this embodiment, platform body 1 is as print media's load-bearing platform, and hole 2 and the groove 3 that induced drafts are used for adsorbing print media to make it paste on platform body 1 flatly. When the printing medium enters from the feeding end of the platform body 1, the nozzle starts ink-jet printing, and different inks are sprayed on the part of the printing medium along with the continuous advance of the printing medium to form a color printing pattern. Along with the increase of ink spraying volume, this part print media's bloated crescent, the area of induced drafting of the groove 3 of induced drafting at this moment crescent to adsorb print media on platform body 1 completely, thereby avoid scraping the shower nozzle because of print media's bloated, the production of printing pattern deformation scheduling problem, owing to adopted the groove 3 of induced drafting instead of induced drafting hole 2 simultaneously, thereby avoided print media to form the pointed protrusion, and also be favorable to print media's follow-up stretching flatly.

Further, the platform body 1 is a rectangular plate.

Furthermore, the left end and the right end of the upper surface of the platform body 1 are rounded. In this embodiment, 1 both ends of platform body form the fillet, can avoid 1 both ends of platform body to the scraping of printing medium, scrape the flower.

Further, a plurality of mounting holes are formed in the position, close to the left end and the right end, of the platform body 1. In this embodiment, the plurality of mounting holes are provided to facilitate connection between the platform body 1 and the inkjet printer.

Example 2:

on the basis of embodiment 1, the air suction groove 3 is in a trapezoid shape with the same depth, the left end of the air suction groove 3 is a trapezoid upper bottom, and the right end of the air suction groove 3 is a trapezoid lower bottom; or, the air suction groove 3 is in a shape of equal width and gradually deepened, and the depth of the left end of the air suction groove 3 is smaller than that of the right end of the air suction groove 3.

In this embodiment, two preferable modes of the air suction groove 3 are provided, so that the air suction area at the left end of the air suction groove 3 is smaller than the air suction area at the right end. The arrangement is that the ink spraying amount on a certain part of the printing medium is gradually increased along with the advance of the printing medium, so that the part of the printing medium needs a larger air suction area to be effectively attached to the platform body 1.

Further, the distance from the left end of the air suction groove 3 to the feeding end of the platform body 1 is 1/4-1/2 of the left-right width of the platform body 1; furthermore, the distance from the left end of the air suction groove 3 to the feeding of the platform body 1 is 1/3 of the left-right width of the platform body 1.

In this embodiment, the suction groove is not disposed near the feeding end of the platform body 1, because the ink spraying amount on the printing medium located at this position is small, the printing medium can be adsorbed on the platform body 1 through the suction hole 2.

Furthermore, the number of the air suction holes 2 in the plurality of air suction grooves 3 is the same or different by one.
