The automatic spraying and coating device has good spraying and coating effect, is reliable in use and flexible to install, and has low use cost.

Description

Automatic spray paint device

Technical field

The utility model belongs to sand casting automatic producing technology field, particularly a kind of device that the sand mold surface is sprayed.

Background technology

The workpiece that needs spray paint or spray paint in the commercial production field, as in clay-bonded sand casting automated production, the sand mold surface often need spray one deck alcohol-base paint.Hand spray exists working strength big, and spraying effect is inhomogeneous.Since the physical characteristic of alcohol-base paint, coating with the alcohol dissolving, but outstanding mixing wherein, coating is static to get off and very soon the coating deposited phenomenon can take place, and therefore when spraying, is easy to take place spray gun, coating pipe choking fault.Adopt the Control During Paint Spraying by Robot mode, invest very high.

Summary of the invention

For solving in the existing clay-bonded sand casting, adopt artificially during to sand mold surface spraying alcohol-base paint, have that working strength is big, the uneven problem of spraying effect, the utility model provides a kind of automatic spray paint device, and its technical scheme is following:

Automatically the spray paint device has the frame along horizontally set, and frame top is vertically arranged with line slideway, and line slideway is connected with the feeding motor through shaft coupling;

The line slideway below is equipped with the feeding panel; Swing mechanism and swing motor are installed on the feeding panel; Said swing mechanism comprises the crank that connects with the output shaft of swing motor; Sliding pin on the crank is sleeved in the chute on the fork, and an end of fork is installed in the rotating shaft on the feeding panel, and the other end is connected with spray gun;

One end of drag chain is installed in the frame bottom, and the other end is connected with line slideway, and drag chain is provided with compressed air piping and coating pipeline;

The output of compressed air piping and coating pipeline is connected with spray gun respectively, and the input of compressed air piping is connected with high-pressure air source, and the input of coating pipeline inserts in the paint can.

Feeding motor in the utility model belongs to micromachine with the swing motor; Drive line slideway and swing mechanism respectively; Control spray gun reciprocation and swing; Final realization coating evenly covers mold cavity surface, thereby motor frequency conversion device control line slideway movement velocity and spray gun hunting frequency reach the purpose of control coating coating thickness.Paint can then is equipped with air motor, plays stirring action, prevents the coating deposition.

The advantage and the beneficial effect of the utility model are: the use of spray paint device has improved sand mold surface coating quality on automatic mo(u)lding line automatically, compare with manual work, and the spraying high conformity, the less foundry goods scab phenomenon that occurs effectively reduces the casting cleaning cost; The use of spray equipment also reduces operator's labour intensity significantly, and the operator only need fill spray to the position that part is difficult to be sprayed onto and get final product, and descends 70% with the labor strength of workload compare operation before.Equipment is simple, and is cheap, and the scope of application is extensive.This device spraying effect is good, uses reliably, installs flexibly, and use cost is cheap.

The specific embodiment

Automatic spray paint device as depicted in figs. 1 and 2 has the frame 1 along horizontally set, and frame 1 top is vertically arranged with line slideway 3, and line slideway 3 is connected with feeding motor 4 through shaft coupling;

Line slideway 3 belows are equipped with feeding panel 9; Swing mechanism 5 and swing motor 8 are installed on the feeding panel 9; Like Fig. 3 and shown in Figure 4, said swing mechanism 5 comprises the crank 10 that connects with the output shaft of swing motor 8, and the sliding pin 11 on the crank 10 is sleeved in the chute 13 on the fork 12; One end of fork 12 is installed in the rotating shaft 14 on the feeding panel 9, and the other end is connected with spray gun 6;

One end of drag chain 2 is installed in frame 1 bottom, and the other end is connected with line slideway 3, and drag chain 2 is provided with compressed air piping and coating pipeline;

The output of compressed air piping and coating pipeline is connected with spray gun 6 respectively, and the input of compressed air piping is connected with high-pressure air source, and the input of coating pipeline inserts in the paint can.

During use, above-mentioned automatic spray paint device is installed in the die cavity of sand mold 7 and can sprays operation mold cavity surface.

Line slideway 3 is done rectilinear motion and swing respectively with swing mechanism 5 under the driving of feeding motor 4 and swing motor 8.The coating of spray gun 6 ejections covers workpiece, i.e. the sand mold surface.

Swing mechanism motion principle such as Fig. 3 and shown in Figure 4:

Swing motor 8 drives cranks 10 and does circumference and rotate, and moves reciprocatingly in the chute 13 of sliding pin 11 on fork 12, drives fork 12 and swings up and down, and spray gun 6 is with fork 12 swing that is rigidly connected.
