Description

Technical Field

[0001] The utility model belongs to the technical field of spraying devices, and particularly relates to a spraying device for coatings. Background Art

[0002] In the related art, the spraying device includes a hopper assembly, a pneumatic compressor assembly and a spray gun assembly. The hopper assembly is adapted to contain the coating. The coating in the hopper can be transported to the spray gun assembly through a delivery pipe. Subsequently, the high-pressure gas generated by the pneumatic compressor assembly is transported to the spray gun assembly through an air pipe. Thus, the coating and the high-pressure gas are mixed in the spray gun assembly, so that the spray gun assembly sprays the coating in an atomized form. In the prior art, the volume of the hopper is small, resulting in the need for the staff to add the coating to the hopper multiple times during the spraying work, thereby leading to low spraying work efficiency.

[0029] Embodiment 1:

[0030] As Figures 1-3 shown, the present utility model provides a spraying device 1 for coatings, including: a base 10, a first housing 20, and a second housing 30. The first housing 20 is connected to the base 10. A first accommodating cavity 21 is provided inside the first housing 20. An open opening communicating with the first accommodating cavity 21 is provided on the side wall of the first housing 20. The second housing 30 is movably connected to the first housing 20. A second accommodating cavity 31 is provided inside the second housing 30. The first accommodating cavity 21 communicates with the second accommodating cavity 31. Wherein the second housing 30 can selectively move towards the first housing 20 so that at least part of the second housing 30 is received in the first accommodating cavity 21 through the open opening. A feed inlet 32 communicating with the second accommodating cavity 31 is provided at the top of the second housing 30.

[0031] In some embodiments, the first housing 20 is fixedly connected to the top of the base 10. A first accommodating cavity 21 is provided inside the first housing 20. An open opening is provided on the side wall of the first housing 20, and the open opening is communicated with the first accommodating cavity 21. The second housing 30 is movably connected to the first housing 20, and at least part of the second housing 30 is movably inserted through the open opening. Thus, the second housing 30 moves to selectively receive at least part of itself in the first accommodating cavity 21. A feed inlet 32 is provided at the top of the second housing 30.

[0032] It should be noted that rotation is a subordinate concept of movement (rotation is movement at the microscopic level). Thus, in the above setting, the second housing 30 can simply move relative to the first housing 20, or the second housing 30 can rotate relative to the first housing 20. There is no restriction here.

[0033] It can be understood that the base 10 serves as the basic support of the entire device, and the base 10 can ensure the stability of the spraying device 1; the first housing 20 is one of the main frameworks of the device. The first accommodation cavity 21 provided inside the first housing 20 provides necessary space for other components, such as paint storage, mechanical structure, or control system, etc. The open design allows the access and removal of the second housing 30, increasing the flexibility and expandability of the device.

[0034] As a movable component, the second housing 30 is designed to provide a dynamic paint storage or processing space. The second accommodation cavity 31 is directly communicated with the first accommodation cavity 21, and the paint can directly flow from the second housing 30 into relevant components inside the first housing 20, such as nozzles or mixers, so as to achieve the spraying operation.

[0035] The second housing 30 can selectively move towards the first housing 20 so that part or all of the second housing 30 is received in the first accommodation cavity 21. Thus, when at least part of the second housing 30 is received in the first accommodation cavity 21, the amount of paint that the spraying device 1 can store is the volume of the first accommodation cavity 21. When the second housing 30 moves away from the first housing 20, the amount of paint that the spraying device 1 can store is the volume of the first accommodation cavity 21 plus the volume of the second accommodation cavity 31, avoiding adding paint to the spraying device 1 multiple times during the spraying operation and improving the efficiency of the spraying work.

[0036] It should be noted that when the spraying device 1 of the present application is not in use, the staff can receive at least part of the second housing 30 in the first accommodation cavity 21, thereby reducing the volume of the spraying device 1 and facilitating the transportation or storage of the spraying device 1.

[0037] The feed inlet 32 is located at the top of the second housing 30. Paint can enter the second accommodating cavity 31 and the first accommodating cavity 21 in sequence through the feed inlet 32. Compared with the conventional implementation where the feed inlet is provided at the top of the first housing, the height of the feed inlet 32 from the ground in this application is lower, making it more convenient to add paint. At the same time, after the second housing 30 moves towards the first housing 20 and at least part of itself is received in the first accommodating cavity 21, the feed inlet 32 is also located within the first accommodating cavity 21. At this time, the feed inlet 32 is isolated from the external environment, preventing dust or foreign objects in the external environment from entering the second accommodating cavity 31 or the first accommodating cavity 21 through the feed inlet 32, improving the spraying quality of the spraying device 1. At the same time, through the above settings, it is possible to avoid cleaning the first accommodating cavity 21 and the second accommodating cavity 31 before using the spraying device 1, reducing the cleaning frequency of the spraying device 1, thereby reducing the working intensity of the staff. At the same time, the time spent on spraying work can be reduced, improving the efficiency of the spraying work.

[0038] For the spraying device 1 for paint according to the present utility model, the second housing 30 can selectively move towards the first housing 20 so that at least part of the second housing 30 is received in the first accommodating cavity 21 through the open opening. At the same time, a feed inlet 32 communicating with the second accommodating cavity 31 is provided at the top of the second housing 30. Thus, when the second housing 30 is away from the first housing 20, the amount of paint that the spraying device 1 can accommodate is the sum of the volumes of the first accommodating cavity 21 and the second accommodating cavity 31, enabling the spraying device 1 to accommodate a larger amount of paint, avoiding adding paint to the spraying device 1 multiple times during the spraying process, and improving the efficiency of the spraying work. At the same time, after at least part of the second housing 30 is received in the first accommodating cavity 21, the feed inlet 32 of the spraying device 1 is also located within the first accommodating cavity 21, enabling the feed inlet 32 to be isolated from the external environment and preventing dust or foreign objects in the external environment from entering the second accommodating cavity 31 or the first accommodating cavity 21, improving the spraying quality of the spraying device 1.

[0039] Embodiment Two:

[0040] Based on Embodiment One, in this embodiment, one side of the second housing 30 facing the first housing 20 is open, and the second housing 30 can selectively move towards or away from the first housing 20 in the length direction.

[0041] It can be understood that one side of the second housing 30 facing the first housing 20 is open. Thus, without the need for additional tools or complex operations, the staff can directly access the second accommodating cavity 31 inside the second housing 30, facilitating the rapid filling of paint, as well as the inspection and cleaning of the first accommodating cavity 21 and the second accommodating cavity 31. At the same time, it is also convenient for maintaining or replacing any components inside the second housing 30.

[0042] The second housing 30 can move towards or away from the first housing 20 in the length direction, and the staff can flexibly adjust the position of the second housing 30 according to the current operation requirements. For example, during spraying operations, moving the second housing 30 closer to the first housing 20 can shorten the paint transmission path and improve spraying efficiency; while when adding paint or cleaning the second housing 30, it can be pulled away for easy operation; of course, when the second housing 30 is away from the first housing 20, the spraying device 1 can store more paint, avoiding adding paint to the spraying device 1 multiple times during the spraying process and improving the efficiency of the spraying work.

[0043] Thus, the open design and the mobility in the length direction of the second housing 30 greatly simplify the paint filling and replacement process. It can be easily completed without complex disassembly steps, significantly improving work efficiency. At the same time, when the spraying device 1 is not in use, the second housing 30 can be completely or partially received within the first housing 20, making the structure of the spraying device 1 more compact during transportation and storage, reducing the volume of the spraying device 1 and lowering the logistics cost. And at the same time, by adjusting the distance between the second housing 30 and the first housing 20, the paint flow path can be optimized, reducing unnecessary delays or pressure losses, thereby increasing the spraying speed and accuracy and ensuring the uniformity and quality of the coating.

[0044] According to some embodiments of the present invention, the inner wall of the first accommodation cavity 21 is provided with a first sliding cooperation portion 22, and the second housing 30 is provided with a second sliding cooperation portion 33 that cooperates with the first sliding cooperation portion 22, and the first sliding cooperation portion 22 and / or the second sliding cooperation portion 33 extend in the length direction.

[0045] In some embodiments, one of the first sliding cooperation portion 22 and the second sliding cooperation portion 33 is configured as a first chute, and the other of the first sliding cooperation portion 22 and the second sliding cooperation portion 33 is configured as a first slider, and the first slider is movably received within the first chute.

[0047] Of course, it can be that the first slider extends in the length direction; or it can be that the first chute extends in the length direction; or it can be that both the first slider and the first chute extend in the length direction, and there is no limitation here either.

[0048] It can be understood that the inner peripheral wall of the first sliding groove can restrict the outer peripheral wall of the first slider, so that the first slider can stably move along the extending direction of the first sliding groove (when the first sliding groove extends in the length direction, or when both the first sliding groove and the first slider extend in the length direction), and further the second housing 30 can stably move relative to the first housing 20 in the length direction; or the outer peripheral wall of the first slider can restrict the inner peripheral wall of the first sliding groove, so that the first sliding groove can stably move along the extending direction of the first slider (when the first slider extends in the length direction, or when both the first sliding groove and the first slider extend in the length direction), and further the second housing 30 can stably move relative to the first housing 20 in the length direction.

[0049] Embodiment Three:

[0051] Rotation is a subordinate concept of movement (rotation is movement at the microscopic level). In some embodiments, the second housing 30 can be selectively rotated relative to the first housing 20 so that at least part of the second housing 30 is received in the first accommodation cavity 21. When the second housing 30 is far from the first housing 20, the amount of paint that the spraying device 1 can hold is more, improving the efficiency of the spraying work, and at the same time, it is convenient to clean the first accommodation cavity 21 and the second accommodation cavity 31; when at least part of the second housing 30 is received in the first accommodation cavity 21, the spraying device 1 is more compact in volume, reducing the space occupied by the spraying device 1 and facilitating the storage and transportation of the spraying device 1.

[0052] According to some embodiments of the present invention, the inner wall of the first accommodation cavity 21 is provided with a third sliding fit portion 23, the second housing 30 is provided with a fourth sliding fit portion that cooperates with the third sliding fit portion 23, and the extending path of the third sliding fit portion 23 and / or the fourth sliding fit portion is arc-shaped. It can be understood that the extending path of the third sliding fit portion 23 and / or the fourth sliding fit portion being arc-shaped enables the second housing 30 to stably rotate relative to the first housing 20, thereby improving the working stability of the spraying device 1.

[0053] In some embodiments, one of the third sliding fit portion 23 and the fourth sliding fit portion is configured as a second sliding groove, and the other of the third sliding fit portion 23 and the fourth sliding fit portion is configured as a second slider, and the second slider is movably received in the second sliding groove.
