Description

Technical Field

[0001] The utility model relates to the technical field of lost foam casting, in particular to lost foam coating spraying equipment. Background Art

[0002] Lost foam casting, also known as vaporization mold casting or full mold casting, is an advanced casting process that uses foam or paraffin models, similar to the use of wax models in traditional investment casting. In the lost foam casting process, a foam or paraffin model with the same size and shape as the casting is first made. These models can be combined together to form a model cluster. Then, refractory materials are coated on the models to prevent direct contact between the molten metal and the sand to avoid sand sticking problems. Next, these models are buried in dry quartz sand for vibration molding, and molten metal is poured under negative pressure. Due to the high temperature, the foam or paraffin model will vaporize and disappear, and the molten metal will replace the model and cool and solidify to form a casting.

[0003] In the lost foam casting process, the application of coating is an indispensable part. In the prior art, the lost foam coating spraying is mostly carried out by manual operation or simple mechanical spraying. This method is not only inefficient, but also has unstable spraying quality, which easily causes coating waste and environmental pollution. Therefore, a new type of lost foam coating spraying equipment is urgently needed to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to provide a lost foam coating spraying device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lost foam coating spraying equipment, comprising a main frame, a servo motor and a linkage mechanism, a servo motor is installed on the upper back of the main frame, a rotating wheel is installed on the output end of the servo motor, a linkage mechanism is installed on one side of the main frame, a threaded rod is installed inside the linkage mechanism through a bearing, a transmission wheel is installed on the top of the threaded rod, a cross arm is installed inside the linkage mechanism through a slide rail, a threaded sleeve is provided at one end of the cross arm, and the cross arm is installed with the threaded rod through the threaded sleeve, a nozzle is installed on one side of the cross arm, a dust removal box is installed on the front of the main frame, a filter element is installed inside the dust removal box, four groups of exhaust fans are equidistantly installed on one side of the dust removal box, and a controller is provided on the back side of the main frame.

[0006] When in use, the device should be stably placed in the designated position, and the nozzle should be connected to an external paint pump (not shown in the figure). The nozzle can be opened by the controller to spray the paint in uniform and fine mist particles, thereby improving the adhesion and spraying efficiency of the paint. The operation of the servo motor can be controlled by the controller to drive the threaded rod to rotate, providing power for the vertical movement of the threaded sleeve, cross arm and nozzle, so that the position of the nozzle can be adjusted up and down, and the spraying range of the nozzle can be adjusted by adjustment. The controller adopts a PLC control system, which can programmably set spraying process parameters, such as spraying time, spraying thickness, etc., to realize the automation and intelligence of the spraying process. The exhaust fan is started during the spraying process, and negative pressure is generated inside the dust removal box through the operation of the exhaust fan. The filter element has good filtering performance, which reduces pollution to the environment by absorbing and filtering the waste mist generated during the spraying process, and is more environmentally friendly.

[0007] Preferably, the servo motor, exhaust fan and nozzle are electrically connected to the controller, and the servo motor, exhaust fan, nozzle and controller are all electrically connected to an external power supply.

[0008] Since the servo motor, exhaust fan and nozzle are electrically connected to the controller, it is convenient for the staff to control the operation of the servo motor, exhaust fan and nozzle through the controller so that various electrical equipment inside the device can operate in a coordinated manner.

[0009] Preferably, a transmission belt is sleeved on the outside of the transmission wheel, and one end of the transmission belt is sleeved on the outside of the rotating wheel.

[0010] Because the transmission wheel and the rotating wheel can be driven by a transmission belt, the rotating wheel can drive the transmission wheel to rotate, thereby driving the threaded rod to rotate.

[0011] Preferably, the nozzle is connected to an external paint source, and a mesh cover is installed on the front of the dust removal box.

[0012] The nozzle is connected to an external paint source, and the paint can be sprayed on the outer surface of the workpiece through the nozzle. The mesh cover can protect the internal components of the dust removal box and play a role in preliminary filtering.

[0013] Preferably, a digital display screen is installed above the front of the controller, and buttons are installed below the front of the controller.

[0014] Through the coordinated use of the digital display screen and buttons, it is convenient for the staff to set the operating parameters of the controller and use the controller. The controller adopts a PLC control system, which is a digital logic control device commonly used in automation control in the prior art.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] The utility model can control the opening of the nozzle through a controller to spray the paint in uniform and fine mist particles. The operation of the servo motor can drive the threaded rod to rotate, providing power for the vertical movement of the threaded sleeve, the cross arm and the nozzle, so that the position of the nozzle can be adjusted up and down, and the spraying range of the nozzle can be adjusted by adjustment. The exhaust fan is started during the spraying process, and negative pressure is generated inside the dust removal box through the operation of the exhaust fan. The filter element has good filtering performance, and the waste mist generated during the spraying process is absorbed and filtered to reduce pollution to the environment, and the environmental protection is better. The controller adopts a PLC control system, and the spraying process parameters, such as spraying time, spraying thickness, etc., can be programmably set to realize the automation and intelligence of the spraying process.

[0022] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0023] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0024] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0025] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms.
