Description

Technical Field

[0001] This utility model relates to the field of lost foam coating technology, specifically to a multi-functional spray coating integrated machine. Background Technology

[0002] In lost-mold casting, to improve the surface quality of castings, a layer of refractory material is usually applied to the surface of the foam mold. Two to three coats are needed to achieve the required thickness. This material supports and protects the foam mold, prevents liquid metal from seeping into the sand and causing sand adhesion, absorbs pyrolysis products, allows pyrolysis gases to pass through the coating, maintains the integrity of the cavity gaps formed after the foam mold pyrolysis, and prevents the heat of the liquid metal from dissipating too quickly. This reduces the surface roughness of the casting, ensures casting accuracy, and reduces or prevents defects such as sand adhesion, sand holes, porosity, metal penetration, cold shuts, incomplete pouring, and carbon buildup.

[0003] The existing method of manual dip coating is labor-intensive. The models are made of foam and are made of multiple glued model clusters, which can easily lead to model deformation and damage. During the brushing process, paint will flow onto the ground, which will not only waste paint, but also damage the cleanliness of the work environment. After the model is finished painting, the paint needs to be leveled. If the model is placed directly on the drying rack after dip coating, paint will flow onto the ground, which will waste paint and damage the ground environment. Therefore, a multi-functional spray coating and curtain coating integrated machine is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional spray coating and curtain coating integrated machine to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A multi-functional spray coating integrated machine includes a holding mechanism, a spraying mechanism is provided at one end of the top surface of the holding mechanism, the holding mechanism includes a moving wheel, a rotating shaft is rotatably connected to the outer surface of the moving wheel, a fixed plate is rotatably connected to the top surface of the rotating shaft, a material hopper is fixedly connected to the top surface of the fixed plate, and the number of fixed plates is four, which are neatly arranged on the bottom surface of the material hopper.

[0007] A further improvement of this utility model is that: a bracket is fixedly connected to the inner side of the hopper, and the number of brackets is two, with the other bracket fixedly connected to the other side of the hopper.

[0008] A further improvement of this utility model is that: a movable grate is movably connected to the top surface of the support, a movable baffle is movably connected to one side of the top surface of the hopper, and a paint recycling tank is provided on the other side of the interior of the hopper.

[0009] A further improvement of the present invention is that: a paint return tank is fixedly connected to the side of the hopper, a paint leveling frame is fixedly connected to the top surface of the paint return tank, and an installation plate is fixedly connected to the other side of the hopper.

[0010] A further improvement of the present invention is that the spraying mechanism includes a recovery pipe, the recovery pipe is fixedly connected to the output end of the paint recovery tank, the output end of the recovery pipe is fixedly connected to a water pump, the water pump is fixedly connected to the side of the material hopper, the output end of the water pump is fixedly connected to a water valve, and the output end of the water valve is fixedly connected to a material conveying pipe.

During the spraying and coating process, the movable baffle can be adjusted to a suitable angle to ensure smooth operation. The paint will not splash outside the hopper. During dip coating, the movable grate can be removed so that the model can be placed directly into the hopper, allowing the paint inside the hopper to contact the model. The device can be moved to a suitable position by using a fixed plate, a rotating shaft, and moving wheels. After the dip coating operation is completed, the dip-coated or spray-coated model is placed on the top surface of the paint leveling frame.

[0020] The present invention will be further described in detail below with reference to embodiments:

[0021] Example 1

[0022] like Figure 1-4 As shown, this utility model provides a multi-functional spray coating integrated machine, including a holding mechanism 1. A spraying mechanism 2 is provided at one end of the top surface of the holding mechanism 1. The holding mechanism 1 includes a moving wheel 111. A rotating shaft 110 is rotatably connected to the outer surface of the moving wheel 111. A fixing plate 19 is rotatably connected to the top surface of the rotating shaft 110. A material hopper 11 is fixedly connected to the top surface of the fixing plate 19. There are four fixing plates 19, which are neatly arranged on the bottom surface of the material hopper 11. A bracket 12 is fixedly connected to the inner side of the material hopper 11. There are two brackets 12, and the other bracket 12 is fixedly connected to the other inner side of the material hopper 11.

[0023] In this embodiment, the bracket 12 and the movable grate 13 enable the entire device to perform different spraying and coating operations on the model. The choice between spraying or coating can be determined based on the size of the model. Small models can be placed in the hopper 11 for immersion coating or placed on the top surface of the movable grate 13 for spraying by the spraying mechanism 2. During the spraying and coating process, the movable baffle 14 can be adjusted to a suitable angle to prevent paint from splashing outside the hopper 11. When immersion coating is performed, the movable grate 13 can be removed so that the model can be placed directly into the hopper 11, allowing the paint inside the hopper 11 to contact the model. The device can be moved to a suitable position by the cooperation of the fixed plate 19, the rotating shaft 110, and the moving wheels 111.

[0024] Example 2

[0025] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a movable grate plate 13 is movably connected to the top surface of the support 12, a movable baffle 14 is movably connected to one side of the top surface of the hopper 11, a paint recycling tank 17 is provided on the other side of the interior of the hopper 11, a paint return tank 15 is fixedly connected to the side of the hopper 11, a paint leveling frame 16 is fixedly connected to the top surface of the interior of the paint return tank 15, and an installation plate 18 is fixedly connected to the other side of the hopper 11.

[0026] In this embodiment, after the dip coating operation is completed, the dip-coated or spray-coated model is placed on the top surface of the paint leveling frame 16. The paint on the surface of the model will level under the influence of gravity. Excess paint will flow into the paint return pool 15, slide into the hopper 11 through the slope of the paint return pool 15, and return to the spraying mechanism 2 through the paint recycling pool 17.

[0027] Example 3

[0028] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the spraying mechanism 2 includes a recovery pipe 21, which is fixedly connected to the output end of the paint recovery tank 17. A water pump 22 is fixedly connected to the output end of the recovery pipe 21. The water pump 22 is fixedly connected to the side of the material hopper 11. A water valve 23 is fixedly connected to the output end of the water pump 22. A conveying pipe 28 is fixedly connected to the output end of the water valve 23. An inlet 27 is fixedly connected to the side of the conveying pipe 28. A paint storage chamber 24 is fixedly connected to the side of the inlet 27. The paint storage chamber 24 is fixedly connected to the top surface of the mounting plate 18. A top cover 26 is fixedly connected to the top surface of the paint storage chamber 24. A discharge valve 25 is fixedly connected to the output end of the paint storage chamber 24.

[0029] In this embodiment, the spraying mechanism 2 can be installed on the side of the hopper 11 via the mounting plate 18, and the paint can be added directly to the inside of the paint storage chamber 24 via the top cover 26. A spray gun can be connected to the outer surface of the discharge valve 25 so that the paint can be sprayed evenly onto the model surface. When there is excess paint inside the hopper 11, the excess paint can be pumped into the paint storage chamber 24 for recycling through the cooperation of the recovery pipe 21 and the water pump 22 via the conveying pipe 28.

[0030] The working principle of this multi-functional spray coating and spray painting machine will be explained in detail below.

[0031] like Figure 1-4 As shown, paint is added to the paint storage bin 24 by opening the top cover 26. Depending on the size of the actual model, spraying or dipping can be selected. When the model is small, dipping or spraying / spraying can be chosen. When spraying / spraying is selected, the model is placed on the top surface of the movable grate 13, reducing the worker's bending angle and ensuring the paint is evenly applied to the model surface. Adjusting the model ensures its surface is completely coated with paint. During spraying / spraying, the movable baffle 14 can be adjusted to a suitable angle to prevent paint from splashing outside the hopper 11. When the model is large, the movable grate 13 is removed, allowing the model to be placed directly into the hopper 11. The paint inside the hopper 11 comes into contact with the model, and spraying technology is used at the same time to speed up the coating process. After the dip coating operation is completed, the dip-coated or spray-coated model is placed on the top surface of the paint leveling rack 16. The paint on the model surface will level under the influence of gravity. Excess paint will flow into the paint return pool 15 and slide into the hopper 11 through the slope of the paint return pool 15. It will then return to the spraying mechanism 2 through the paint recovery pool 17. When there is excess paint in the hopper 11, the excess paint can be pumped to the paint storage bin 24 through the conveying pipe 28 for recycling through the cooperation of the recovery pipe 21 and the water pump 22.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
