Description
Technical Field
The invention relates to the field of printers, in particular to a printing medium flattening device of a printer.
Background
The printing machine is one of printers, and is widely applied to the fields of textile, home decoration, building materials, decoration and the like.
In the fields of home decoration and textile, for example, products such as curtains, quilt covers, sheets and the like, the current main printing and dyeing mode is realized by adopting a roll printing mode, and the patterns of a mould on the roll printing mode are printed on cloth after being adhered with dye to form the products with the patterns.
The roll printing mode is relatively backward, the required ink amount is large, more pollution is caused in the printing and dyeing process, and the environment protection is not good.
Therefore, the application requirement of the printing machine in the field is gradually improved, after the pattern is printed on the paper by the printing machine, the pattern is transferred to the cloth in a heat transfer mode, and the method has the advantages that the ink quantity demand and waste are less, the transferred pattern unit is relatively larger, the continuously changed pattern can be transferred theoretically, the limitation of equipment is avoided, the individualization capacity is greatly improved, and the product is relatively high-end.
However, in the thermal transfer process, the cost of the transfer medium, namely the transfer paper, becomes an obstacle for limiting the application of the printing machine, in order to pursue profit and improve the competitiveness of products, the material manufacturers make the transfer paper thinner and thinner, the cost of the thin paper can be reduced, but the defect of the thin paper is obvious, the thin paper is easily stretched and deformed in the printing process, especially, the paper is soaked by ink after printing is finished, and the paper is easily slightly wrinkled under the action of a certain tension force, and the wrinkling can hardly be avoided.
The technical personnel in the field provide several directions to this problem, one is the performance that promotes the printer shower nozzle, can spout the seal more meticulous, and the second is to promote the ink performance, reduces the influence to the paper, and the third is the performance that improves the paper, strengthens the crease-resistant ability of paper, and the fourth is that the upgrading of carrying out printing apparatus reforms transform, reduces the influence of fold to minimum.
The degree of difficulty of first three direction is higher relatively, and this application mainly improves to the fourth direction to solve the fold problem of thin paper.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a printing medium flattening device of a printer, which has a better flattening effect on thin media and avoids excessive deformation of the thin media after printing.
In order to achieve the purpose, the invention adopts the technical scheme that: a printing medium flattening device of a printer comprises a frame, and a paper feeding end brush roller, a printing panel and a paper outlet end brush roller which are respectively arranged on a support;

the paper outlet end brush roller, the drying oven, the second tension rod, the spiral yarn dividing roller, the spreading roller, the damping roller and the paper collecting roller are arranged on the rear side of the printing panel according to the printing path sequence.
Basically, the first tension rod and the second tension rod are both swing rods.
Basically, the spreading roller is a roller with a roll surface with curvature.
Basically, a negative pressure air draft device is installed below the printing panel and comprises a negative pressure cavity matched with the printing panel and a negative pressure fan communicated with the negative pressure cavity.
Compared with the prior art, the invention has outstanding substantive characteristics and remarkable progress, and particularly, the invention supports the printing medium by respectively arranging two brush rollers at the front side and the rear side of the printing panel and utilizing the number of the brushes densely distributed on the brush rollers, because the gaps between the bristles in the hairbrush are small enough, each bundle of bristles can support the paper, the paper can be spread by the support of the small gaps, the wrinkle deformation of the paper is maximally dispersed among each bundle or each hair, compared with the problem that continuous large-size wrinkles are easy to appear on the surface of a traditional plane roller, the method disperses and even reduces the area which should be the large-size wrinkles originally, and further ensures that the area of a single wrinkle is small enough, the transfer printing method belongs to an acceptable range during transfer printing, and particularly can avoid the serious problem that the subsequent winding roller system is overlapped due to overlarge wrinkles.
Furthermore, at the paper feeding end, the brush roller is lower than the printing panel, paper is not printed yet, the angle can help the paper to be more closely attached to the printing panel and is also beneficial to flattening the paper, a groove and a boss which are arranged on the printing panel can effectively support the paper on one hand, and on the other hand, the paper can be stably adsorbed on the printing panel under the action of negative pressure air suction, a certain downward bending deformation can be further formed at the groove, the deformation amount is controlled within the allowable range of transfer printing precision, the downward deformation can increase the resistance of the paper to bulge, and the occurrence of bulging is avoided; and go out the paper end design and be with printing the panel parallel and level, avoid being excessively dragged by wetted printing paper, lead to deformation.
Further, the brush is designed into a plastic brush with elastic deformation capacity, so that deformation can be caused under a pressure-bearing state, and the printing paper is prevented from being broken due to overlarge supporting force.
Furthermore, a roller system is arranged in a targeted manner, a tension rod is arranged at the paper feeding end of the printing panel for sufficient tensioning, a series of rollers capable of flattening the paper are arranged at the paper discharging end, such as the tension rod, a yarn dividing roller, an expanding roller and a damping roller, so that the flattening performance of the printing paper is further ensured.
