Description

Technical Field

[0001] This utility model relates to the field of surface treatment of building materials, and in particular to a surface spraying device for building construction materials with a dust protection cover. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. Many construction materials are used in the building construction process, such as wood boards, steel plates, etc. Before use, these construction materials need to be coated with protective coatings to increase their service life.

[0003] According to Chinese Patent No. CN219210421U, a surface spraying device for building construction materials includes a spraying device platform. A protective cover is fixedly installed on the upper surface of the spraying device platform, and a main body of the spraying device is fixedly installed on the top of the protective cover. A carrying platform is set inside the spraying device platform and fixedly installed on the upper surface of the spraying device platform. A drying device is fixedly installed on the inner side of the protective cover, and a stirring device is set on one side of the main body of the spraying device. Although the above patent solution sets a protective cover outside the spraying device, the front of the protective cover is not sealed. During the spraying process, a large amount of spraying dust will still fly out, affecting the processing environment. Therefore, we propose a surface spraying device for building construction materials with a dust protective cover to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a surface spraying device for building construction materials with a dust protective cover, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dust-protective cover for spraying building materials includes a spraying table. A protective cover is fixedly connected to the upper surface of the spraying table. A protective door is provided on the front of the protective cover. The bottom surface of the protective door is hinged to the spraying table via a hinge. An electric push rod is hinged to the front of the spraying table via a first connecting seat. The output end of the electric push rod is connected to the protective door via a second connecting seat. A sprayer is provided inside the protective cover. Multiple nozzles are installed on the bottom surface of the sprayer. A moving mechanism is fixedly connected to the upper surface of the protective cover. The top of the sprayer penetrates the protective cover and is connected to the moving mechanism. A paint tank is fixedly connected to the upper surface of the protective cover.

[0007] In a further embodiment, a sealing cover is installed on the upper surface of the paint tank, a liquid level window is provided on the front of the paint tank, an agitator is installed inside the paint tank, and a first motor is installed on the left side of the paint tank. The output end of the first motor passes through the paint tank and is connected to one end of the agitator.

[0008] In a further embodiment, the moving mechanism includes a housing fixed to the upper surface of the protective cover. A sliding plate is slidably connected inside the housing via a sliding groove. A threaded sleeve is fixedly embedded in the middle of the sliding plate. A lead screw is threadedly connected inside the threaded sleeve. Both ends of the lead screw are rotatably connected to the housing via bearings. A second motor is installed on the back of the housing. The output end of the second motor is connected to one end of the lead screw.

[0009] In a further embodiment, an air pump is installed inside the spraying station, and the output end of the air pump is connected to the paint tank through an air pipe. The paint tank is connected to the sprayer through a connecting pipe.

[0010] In a further embodiment, a ventilation grille is installed on the right side of the spraying station, and two sets of support legs are installed on the bottom surface of the spraying station.

[0011] In a further embodiment, the protective door has a display window on its front, and a controller is installed on the left side of the spraying station.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device only requires placing the material to be sprayed onto the spray table with the protective door open. After closing the protective door, the automatic spraying program can be started via the controller. Throughout the process, personnel are not exposed to the paint mist environment, ensuring high safety. The protective cover and the automatically opening and closing protective door form a complete working space. The controller controls the extension and retraction of the electric push rod, which drives the protective door to open and close smoothly around the hinge. During spraying operations, the protective door remains closed, fundamentally solving the core problem in the background technology that "the front of the protective cover is not sealed, resulting in a large amount of spraying dust flying out." It completely confines the paint mist and dust inside the protective cover, greatly reducing pollution to the processing environment and protecting the health of operators.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this utility model, a surface spraying device for building construction materials with a dust protective cover includes a spraying table 1. A protective cover 8 is fixedly connected to the upper surface of the spraying table 1. A protective door 9 is provided on the front of the protective cover 8. The bottom surface of the protective door 9 is hinged to the spraying table 1 via a hinge. An electric push rod 12 is hinged to the front of the spraying table 1 via a first connecting seat 13. The output end of the electric push rod 12 is connected to the protective door 9 via a second connecting seat 11. A sprayer 16 is provided inside the protective cover 8. The protective cover 8 and the automatically opening and closing protective door 9 form a complete working space. The extension and retraction of the electric push rod 12 is controlled by a controller 14, which can drive the protective door 9 to open and close smoothly around the hinge. During the spraying operation, the protective door 9 remains closed, completely confining paint mist and dust inside the protective cover 8, greatly improving the pollution of the processing environment and protecting the health of the operators.

[0023] Multiple nozzles 18 are installed on the bottom surface of the sprayer 16. A moving mechanism 3 is fixedly connected to the upper surface of the protective cover 8. The top of the sprayer 16 passes through the protective cover 8 and is connected to the moving mechanism 3. A paint tank 5 is fixedly connected to the upper surface of the protective cover 8. A sealing cover 4 is installed on the upper surface of the paint tank 5. A liquid level window 6 is provided on the front of the paint tank 5. An agitator 19 is installed inside the paint tank 5. A first motor 7 is installed on the left side of the paint tank 5. The output end of the first motor 7 passes through the paint tank 5 and is connected to one end of the agitator 19. The agitator 19 inside the paint tank 5 is driven by the first motor 7 and can continuously agitate the paint during the spraying process, effectively preventing pigment sedimentation and paint stratification, and ensuring the uniformity and stability of the output paint composition. An air pump 17 is installed inside the spraying station 1. The output end of the air pump 17 is connected to the paint tank 5 through an air pipe. The paint tank 5 is connected to the sprayer 16 through a connecting pipe. The air pump 17 provides stable pressure for paint delivery. The liquid level window 6 facilitates real-time monitoring of the remaining paint.

[0024] The moving mechanism 3 includes a housing 301 fixed to the upper surface of the protective cover 8. A sliding plate 303 is slidably connected inside the housing 301 via a sliding groove. A threaded sleeve 304 is fixedly embedded in the middle of the sliding plate 303. A lead screw 305 is threadedly connected inside the threaded sleeve 304. The two ends of the lead screw 305 are rotatably connected to the housing 301 via bearings. A second motor 302 is installed on the back of the housing 301. The output end of the second motor 302 is connected to one end of the lead screw 305. The moving mechanism 3 integrated on the upper surface of the protective cover 8 drives the lead screw 305 to rotate through the second motor 302, which drives the threaded sleeve 304 and the sliding plate 303 to move linearly, thereby controlling the sprayer 16 and its multiple nozzles 18 to move at a uniform speed along a predetermined path. This automated spraying mode ensures the uniformity of paint coverage, avoids problems such as uneven thickness and missed spraying caused by manual spraying, and significantly improves the spraying quality and the consistency of product appearance.

[0025] A ventilation grille 2 is installed on the right side of the spraying station 1, and two sets of support legs 15 are installed on the bottom of the spraying station 1. A display window 10 is provided on the front of the protective door 9, and a controller 14 is installed on the left side of the spraying station 1. The operator only needs to put the material to be sprayed into the spraying station 1 with the protective door 9 open, and after closing the protective door 9, the operator can start the automatic spraying program through the controller 14. The operator does not need to be exposed to the paint mist environment during the whole process, which is highly safe. The automated spray gun movement and paint supply also greatly improve the work efficiency. The display window 10 makes it easy to observe the internal spraying status, and the ventilation grille 2 helps the equipment dissipate heat and maintain the internal air pressure balance.

[0026] The working principle of this utility model is as follows:

[0027] The equipment is started by the controller 14, and the electric push rod 12 retracts automatically. Through the linkage of the first connecting seat 13 and the second connecting seat 11, the protective door 9 is opened. The operator places the building construction material to be sprayed (such as wood or steel plate) steadily on the spraying table 1, inside the protective cover 8. The controller 14 controls the electric push rod 12 to extend and push the protective door 9 to close, so that the protective cover 8 forms a relatively sealed working space. The operator can observe the internal situation through the display window 10, open the sealing cover 4, add paint to the paint tank 5, and observe the amount added through the liquid level window 6. The first motor 7 is started to drive the stirring wheel 19 to rotate continuously and slowly in the paint tank 5 to prevent pigment sedimentation in the paint and ensure uniform paint concentration.

[0028] The spraying parameters are set by the controller 14 and the spraying program is started. The air pump 17 is started, applying stable air pressure to the paint tank 5. Under the action of air pressure, the paint is forced into the sprayer 16 through the connecting pipe. At the same time, the second motor 302 of the moving mechanism 3 is started, driving the lead screw 305 to rotate. The threaded sleeve 304, which is threaded with the lead screw 305, drives the sliding plate 303 to make precise linear movements along the sliding groove in the housing 301. The sliding plate 303 drives the sprayer 16 below and its multiple nozzles 18 to move synchronously. Under the action of air pressure, the paint is atomized and sprayed from the nozzles 18. At the same time, the sprayer 16 moves at a uniform speed to ensure uniform and dead-zone-free automated spraying of the workpiece below. Throughout the spraying process, the protective door 9 remains closed, completely sealing all paint mist and dust generated inside the protective cover 8, effectively preventing pollutants from escaping and protecting the workshop environment.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
