Abstract
The invention relates to a stirred tank for producing a light sensitive wet film for a cross board type PCB. The stirred tank comprises a stirring barrel and a stirring mechanism, wherein the stirring barrel comprises two conical stirring cavities; the stirring mechanism comprises two stirring components in mirror symmetry; the stirring components are arranged in the stirring cavities; each stirring component comprises a rotating shaft, a stirring plate array and a push block; each stirring plate array comprises multiple stirring plates of which the areas are gradually increased along the axis of the rotating shaft; the plane of each stirring plate is inclined to the axis of the rotating shaft; the push blocks are cylindrical; inclined surfaces parallel to the stirring plates are formed on the push blocks; the push blocks are fixedly arranged on one sides of the stirring plates with large rotating shaft fixing areas; and one ends of the two conical stirring cavities with small diameters are communicated with each other.
Description
Technical field
The present invention relates to a kind of production stirred tank intersecting the photosensitive wet film of board-like PCB, belong to the production equipment field of photosensitive wet film.
Background technology
Epoxy resin will be included with in photosensitive wet film process by the production stirred tank of the photosensitive wet film of PCB in production PCB (printed substrate), sensitising agent, the filler of solvent is uniformly mixed, the current PCB production stirred tank of photosensitive wet film comprises kettle, rotating shaft, paddle and motor, rotating shaft is arranged in kettle, rotating shaft upper end is stretched out kettle and is connected with motor, paddle is arranged in the kettle of rotating shaft middle-end and lower end, in whipping process, the heat that electric rotary produces easily is transmitted in the material in kettle by rotating shaft, temperature of charge in kettle is constantly raised, when temperature of charge is too high, epoxy resin can produce cross-linking reaction, and sensitising agent can lose efficacy, thus make product quality receive impact.
Summary of the invention
The technical problem to be solved in the present invention is: overcome photosensitive wet film raw material mixing plant weak heat-dissipating in prior art, the technical problem that sensitising agent raw material can be made to lose efficacy, provide a kind of photosensitive wet film material mixing plant of good heat dispersion performance.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of production stirred tank intersecting the photosensitive wet film of board-like PCB, comprise agitator and rabbling mechanism, the stirring cavity of described agitator two tapers, described rabbling mechanism comprises the mixing component that two specular are arranged, and described mixing component is arranged on stirring cavity;
Described mixing component comprises turning cylinder, agitating plate array and pushing block, described agitating plate array comprises the agitating plate that some areas increase gradually along turning cylinder axis, the plane of described agitating plate and the axis of turning cylinder are obliquely installed, described pushing block is cylindrical, pushing block is provided with an inclined-plane parallel with agitating plate, and described pushing block is fixed on the larger agitating plate side of turning cylinder fixed-area;
One end that the stirring cavity diameter of described two tapers is less interconnects.
As further innovation of the present invention, described agitating plate is densely covered with some protruding particles.
As further innovation of the present invention, the internal face of the stirring cavity of described taper is step-like, and the height of described each step equals the amplitude of fluctuation on agitating plate axis direction.
The invention has the beneficial effects as follows:
1, the present invention is by the cooperation of two mixing components, carries out extruding repeatedly, stretching, thus realize the mixing of material to material, during material stirring, temperature is low, stir dead angle less, simultaneously can to the particle of material and the pulverizing carried out to a certain extent of luming, mixing effect is good.
2, protruding particle of the present invention can improve the band efficiency of movement to material, improves the effect of mixing.
3, the stirring cavity of present invention station scalariform can reduce dead angle further, reduces simultaneously and stirs cavity volume, improve stirring efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, intersect the production stirred tank of the photosensitive wet film of board-like PCB, comprise agitator 1 and rabbling mechanism, the stirring cavity of described agitator 1 two tapers, described rabbling mechanism comprises the mixing component that two specular are arranged, and described mixing component is arranged on stirring cavity;
Described mixing component comprises turning cylinder 4, agitating plate 2 array and pushing block 3, described agitating plate 2 array comprises the agitating plate 2 that some areas increase gradually along turning cylinder 4 axis, the plane of described agitating plate 2 and the axis of turning cylinder 4 are obliquely installed, described pushing block 3 is cylindrical, pushing block 3 is provided with an inclined-plane parallel with agitating plate 2, and described pushing block 3 is fixed on larger agitating plate 2 side of turning cylinder 4 fixed-area;
One end that the stirring cavity diameter of described two tapers is less is interconnected by tube connector 5;
Described agitating plate 2 is densely covered with some protruding particles;
The internal face of the stirring cavity of described taper is step-like, and the height of described each step equals the amplitude of fluctuation on agitating plate 2 axis direction;
During stirring, material is placed into and stirs in cavity, the agitating plate 2 be obliquely installed by material dynamically carry out extrude and diastole, thus carry out the mix and blend of material.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
