Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, a paint box with a backflow type paint pulling device comprises a paint box body with an inner cavity 6, and an outer cavity 10 is further arranged on the rear side of the paint box body.

The lacquer box body includes front bezel 1, back plate 2, left side board 3, right side board 4 and bottom plate 5, and front bezel 1, back plate 2, left side board 3, right side board 4 and bottom plate 5 enclose into inner chamber 6. The bottom plate 5 is provided with a paint inlet 5-1. The front plate 1 and the rear plate 2 are provided with through holes which are opposite and communicated with the inner cavity 6. The front baffle 7 is arranged at the through position of the front plate 1, the rear baffle 8 is arranged at the through position of the rear plate 2, and pull rod holes which are opposite to each other are formed in the centers of the front baffle 7 and the rear baffle 8; when the material rod works, the material rod penetrates through the pull rod holes of the front baffle 7 and the rear baffle 8. Preferably, the diameter of the pull rod hole in the center of the rear baffle 8 is 2mm-5mm larger than the diameter of the material rod (range value). The paint pulling skin 9 is fixed on the front baffle 7 through an annular fixing plate 13, and a material rod penetrates through a central hole of the paint pulling skin 9 during operation. The front baffle 7 is used for positioning the paint pulling skin 9, so that the relative position between the paint pulling skin 9 and the material rod is fixed, and the initial positioning of the paint surface on the material rod is achieved. The rear baffle plate 8 mainly plays a role in limiting flow, so that the paint outflow amount in the paint pulling process is small, and the paint can flow back.

An outer cavity plate 11 and two outer cavity side plates 12 are fixedly connected with the upper rear part of the bottom plate 5. The bottom plate 5, the outer cavity plate 11, the back plate 2 and the two outer cavity side plates 12 enclose an outer cavity 10; the return hole 10-1 is arranged on the bottom plate 5 at the lower part of the outer cavity 10, and the drift diameter of the return hole 10-1 is smaller than that of the paint inlet hole 5-1.

When in use, the utility model is used,

the paint inlet 5-1 and the paint return hole 10-1 in the return paint drawing box are both connected with a paint source;

after the material rod is in place,

paint flows into the inner cavity from the paint inlet hole until the paint surface rises to cross the pull rod hole;

then, pulling the rod, wherein in the process, paint flows into the outer cavity from a gap between a pull rod hole in the center of the rear baffle and the material rod;

after the pull rod is finished, the paint surface descends and waits, and at the moment, the paint in the outer cavity flows back from the backflow hole.

In addition, the principle that the outer cavity can flow back is as follows:

because the cross-sectional area of the inner cavity and the outer cavity passing through the paint is different (the inner cavity is far larger than the outer cavity, and the paint inlet hole is larger than the return hole), the paint is liquid with larger viscosity, so that the flow passing through the inner cavity is far larger than the outer cavity, in addition, the paint surface rising time only accounts for about 30 percent of the paint pulling process, and is far shorter than the paint surface falling and waiting time, and the paint of the outer cavity has enough time to return.

The above embodiments can be seen in:

the utility model adopts the inner and outer cavity structure, so that the overflowed paint can flow back, and the problem of paint flowing of the rear baffle is solved;

the utility model discloses saved the drawing lacquer leather of backplate department, eliminated the lacquer leather centre bore and bumped the problem of lacquer with the material pole, guaranteed the japanning effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
