Abstract

The utility model provides a novel ink reclaiming knife for a screen printing machine, which comprises an ink reclaiming knife body. Ink reclaiming blades are arranged at two ends of the ink reclaiming knife body, the inner lateral sides of the ink reclaiming knife body and each ink reclaiming blade are rotatably connected through an elastic device, and an electromagnetic coil is arranged on the ink reclaiming knife body and connected with the same through a coil support. Compared with existing products, the novel ink reclaiming knife has the advantages that the ink reclaiming blades are additionally arranged on the ink reclaiming knife body, contraction of the ink reclaiming blades is controlled by the electromagnetic coil, and accordingly manual times can be reduced and time of suspended manual slurry shifting is shortened. Further, the novel ink reclaiming knife is simple in structure and quite practical, and purposes of the novel ink reclaiming knife can be achieved.

Description

The novel returning blade of screen process press

Technical field

The utility model relates to screen process press and makes field, the novel returning blade of particularly a kind of screen process press.

Background technology

In the positive and negative electrode printing process that crystal silicon solar energy battery is produced, the slurry on the Printing screen can be printed cutter gradually and be extruded into both sides, though existing equipment is equipped with returning blade; But its major function is after being completed for printing, on average to spread upon slurry on the web plate; Be the good slurry of subsequent printings place mat,, still have most of slurry and to return in the black process in printing though the returning blade two ends have certain radian; Be pressed against printing cutter and beyond the returning blade controllable distance; Therefore just need at set intervals artificially to go to dial back the centre position to the slurry at edge with touching cutter, the production that will have influence on sliver of frequent operation has influenced efficient.

Therefore, need the novel returning blade of a kind of screen process press especially, to solve the above-mentioned existing problem that exists.

The utility model content

The purpose of the utility model is to provide a kind of screen process press novel returning blade, and to the defective that prior art exists, the number of times that can reduce artificial treatment just can reduce the time of manually dialling slurry of time-out, increases output, and is simple in structure, very practical.

To achieve these goals, the technical scheme of the utility model is following:

The novel returning blade of a kind of screen process press; It comprises the returning blade body; It is characterized in that; Be provided with the returning blade sheet at said returning blade body two ends, be connected through an elastic device between the medial surface of be rotatably connected between said returning blade body and the returning blade sheet said returning blade body and returning blade sheet; The returning blade body is provided with solenoid, and said solenoid is connected with the returning blade body through coil brace.

The novel returning blade of the screen process press of the utility model; Compare with present product, on the returning blade body, set up the returning blade sheet, and pass through the contraction of solenoid controlled returning blade sheet; The number of times that can reduce artificial treatment just can reduce the time of manually dialling slurry of time-out; Simple in structure, very practical, the purpose of realization the utility model.

The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.

Description of drawings

Fig. 1 is the structural representation of the novel returning blade of screen process press of the utility model;

Fig. 2 is the concave structure sketch map of the novel novel returning blade of screen process press of this use;

Fig. 3 is the convex configuration sketch map of the novel novel returning blade of screen process press of this use.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.

As shown in Figure 1; The novel returning blade of the screen process press of the utility model, it comprises returning blade body 100, it is characterized in that; Be provided with returning blade sheet 200 at said returning blade body 100 two ends, have rotating shaft to be connected 300 between said returning blade body 100 and the returning blade sheet 200.

Of Fig. 2, the novel returning blade of the screen process press of the utility model is connected with an elastic device 220 between said returning blade body 100 and the returning blade sheet 200.

Of Fig. 3, the novel returning blade of the screen process press of the utility model, 100 are provided with solenoid 210 on the returning blade body, and solenoid 210 is connected with the returning blade body through coil brace 211.

Of Fig. 1, print head holder 400 under the dull and stereotyped driven by motor of move left and right, move right (print head 410 is in printing height, and returning blade is in a high position) in the utility model; Contact-making switch 420 leaves the print head holder 400 in left side simultaneously, and contactless contactor 420 is opened, solenoid 210 energisings; Produce magnetic; The returning blade sheet 200 that installs additional is drawn onto on the solenoid 210, and at this moment, returning blade integral body in opened condition; After being completed for printing, returning blade drops to go back to black position, along with dull and stereotyped driven by motor is moved to the left; At this moment, returning blade so just can all bring back to the left side with the slurry that is extruded into the edge still in opened condition; During near the stop position in left side, contact-making switch bumps against left side print head holder 400, and contact-making switch 420 cuts out; Solenoid 210 outages lose magnetism, because the effect of elastic device 220; Whole returning blade becomes to close up state, and the slurry of so just returning marginal belt is brought to the position between print head and the returning blade; Function in the middle of so just having realized automatically the edge slurry being brought to has reduced the artificial frequency of dialling the overfall material and has increased the efficient of producing.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
