Abstract
The utility model discloses an inclined ink return knife for a screen printing machine. The inclined ink return knife for the screen printing machine is composed of a connecting frame and an ink return knife body. The ink return knife body is composed of a knife body portion, two arc flanges and two triangular connecting blocks. The knife body portion is composed of a bar-shaped vertical section and a bar-shaped inclined section. The inclined section is bent and extends from the lower end of the vertical section backwards. The bending angle between the inclined section and the vertical section is smaller than 90 degrees. The height of the arc flanges is identical to that of the knife body portion. The two arc flanges are bent and extend from the left end and the right end of the knife body portion forwards. The triangular connecting blocks are fixedly connected between the inclined section of the knife body portion and the arc flanges. The connecting frame is fixedly connected to the upper end of the vertical section of the knife body portion. According to the inclined ink return knife for the screen printing machine, a region recessed inwards of the inclined section below the ink return knife can be filled with size, the size also can be prevented from moving upwards, the sufficient size is laid on a screen, and the evenness of high-viscosity size ink return is improved.
Description
Technical field
The utility model belongs to screen printing apparatus field, is specifically related to a kind of screen printing machine returning blade.
Background technology
In the processing procedure of solar cell, by serigraphy, electrocondution slurry is printed onto on silicon chip.Serigraphy five is wanted greatly: half tone, frictioning, slurry, print station and stock.Serigraphy basic principle: utilize half tone picture and text part mesh strike through, the non-graphic part mesh not basic principle of strike through prints.During printing, on half tone, add slurry, frictioning applies certain pressure to half tone, moves towards the half tone other end simultaneously.Slurry is expressed on stock in movement from mesh, and due to viscous effect, set within limits.Owing to keeping certain gap between half tone and stock, half tone produces the screen resilience to frictioning by the tension force of self, make half tone and stock only be portable line and contact, and other parts and stock is disengaged position, slurry and silk screen generation rhegmagenesis, guaranteed printed dimensions precision.Frictioning lifted after scraping the whole space of a whole page, and half tone also lifts simultaneously, and by returning blade, slurry is gently scraped back to initial position, completes a print stroke.At present, for improving the conversion efficiency of solar cell, manufacturer uses full-bodied electrocondution slurry to print, use existing returning blade to return when China ink, because the viscosity of slurry is more easily attached on returning blade, cause feed back to tail off, cause back China ink inhomogeneous, and then have influence on printing effect, and easily there are disconnected grid, when serious, there will be the empty phenomenon that prints.Therefore just need at set intervals artificially with perching knife, the slurry on returning blade to be returned to shovel in the middle of half tone, operation will have influence on the production of sliver so frequently, affects operating efficiency.
Utility model content
In order to address the above problem, the utility model provides a kind of screen printing machine tilting returning blade, when this screen printing machine tilting returning blade can effectively avoid existing common returning blade to return China ink because of highly viscous slurry, slurry sticks to and on returning blade, causes printing bad problem, improve the uniformity of highly viscous slurry Hui Mo, and then improved printing effect.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of screen printing machine tilting returning blade, by link and returning blade body, formed, described returning blade body is by cutter body, two arc block edges and two triangle contiguous blocks form, described cutter body consists of vertical section of horizontal stripe shape and the tilting section of horizontal stripe shape, described tilting section be from the lower end of described vertical section backward bending extend and form, and the bending angle between described tilting section and described vertical section is less than 90 °, the height of described arc block edge is identical with the height of described cutter body, and two arc block edges are respectively to extend and form from the two ends, left and right of described cutter body bend forward, and described triangle contiguous block is fixedly connected between the tilting section and described arc shelves edge of described cutter body, described link is fixedly connected on the upper end of vertical section of described cutter body.
Preferably, the bending angle between described tilting section and described vertical section is 70 °.
The beneficial effects of the utility model are: screen printing machine tilting returning blade of the present utility model is by being improved as tilting returning blade by current straight returning blade, make slurry be filled into the region that returning blade below tilting section falls in, the returning blade tilting also can stop slurry to move upward, thereby can there be enough slurries to be paved with half tone, improve the uniformity of highly viscous slurry Hui Mo, and then improved printing effect.The utility model returning blade coordinates the use of highly viscous slurry, and making to print depth-width ratio has had raising significantly, and the photoelectric transformation efficiency of battery also can promote to some extent.
Accompanying drawing explanation
Fig. 1 is returning blade schematic appearance of the present utility model;
Fig. 2 is the A-A portion profile of Fig. 1.
The specific embodiment
By specific instantiation, the specific embodiment of the present utility model is described below, those skilled in the art can understand advantage of the present utility model and effect easily by content disclosed in the present specification.The utility model also can other different mode be implemented, and, under the category not disclosing departing from the utility model, can give different modifications and change that is.
Embodiment: a kind of screen printing machine tilting returning blade, by link 1 and returning blade body, formed, described returning blade body is by cutter body, two arc block edges 23 and two triangle contiguous blocks 24 form, described cutter body consists of vertical section 21 of horizontal stripe shape and the tilting section 22 of horizontal stripe shape, described tilting section be from the lower end of described vertical section backward bending extend and form, and the bending angle between described tilting section and described vertical section is less than 90 °, bending angle the best be 70 °, the height of described arc block edge is identical with the height of described cutter body, and two arc block edges are respectively to extend and form from the two ends, left and right of described cutter body bend forward, and described triangle contiguous block is fixedly connected between the tilting section and described arc shelves edge of described cutter body, described link is fixedly connected on the upper end of vertical section of described cutter body.
Use returning blade of the present utility model, while returning China ink, can make slurry be filled into the region that returning blade below tilting section falls in, the returning blade tilting also can stop slurry to move upward, thereby can there be enough slurries to be paved with half tone, improve the uniformity of highly viscous slurry Hui Mo, and then improved printing effect.Moreover the utility model returning blade coordinates the use of highly viscous slurry, making to print depth-width ratio has had raising significantly, and the photoelectric transformation efficiency of battery also can promote to some extent.
