Description
Technical field
The present invention relates to the production stirred tank of the photosensitive wet film of a kind 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 board-like PCB production stirred tank for photosensitive wet film, comprise bucket and rabbling mechanism and support, described rabbling mechanism and bucket are fixed on support, and described bucket is arranged on the below of rabbling mechanism;
Described rabbling mechanism comprises fixed head and rotor plate, and described rotor plate is rotationally connected by a turning cylinder and frame upper, and described fixed head is fixed on the bottom of support;
The middle part of described fixed head is provided with the hopper of a taper, and described hopper is communicated with bucket by a drainage conduit;
Described fixed head is provided with some concentric annular protrusions, described annular protrusion is provided with some breach, the breach of described adjacent two annular protrusions is arranged in a crossed manner;
Described rotor plate is provided with some at the diametric raised item of rotor plate, between raised item, is provided with some charging holes;
Be provided with between fixed head and rotor plate and stir gap, the top of described rotor plate is provided with feed pipe, and the port of export of described feed pipe is towards charging hole.
As further innovation of the present invention, described fixed head and rotor plate are taper, the most advanced and sophisticated bottom towards support of taper of described fixed head and rotor plate.
As further innovation of the present invention, described rotor plate is fixing on the rotating shaft by a slip cap, and described slip cap arranges spring, and described rotor plate is connected with rack elasticity by spring.
The invention has the beneficial effects as follows:
1, the present invention is by the cooperation of two agitating plates, realizes the stirring to material, the effect that larger contact surface ensures heat radiation and stirs, and compared to traditional agitator, good heat dissipation effect of the present invention, later stage clean and maintenance is also more convenient.
2, taper agitating plate of the present invention can prevent material from dropping out when stirring, and also can increase the evenness of material stirring simultaneously.
3, rotor plate of the present invention is connected with rack elasticity, when rotor plate and fixed head relatively rotate, can provide certain buffering, improves stability, reduces the damage probability of rotor plate and fixed head.
