Description

Technical Field

[0001] This utility model relates to a spraying device, and more particularly to a synchronously adjustable double-sided spraying device. Background Technology

[0002] If a component needs to be given additional properties, such as waterproofing, rust resistance, or for protective or other purposes, a coating will be sprayed onto its surface. The coating is applied to the component surface as evenly as possible using a spray gun or nozzle.

[0003] However, if the workpiece has more than one spraying surface, such as when the workpiece is cylindrical, it is necessary to rotate the workpiece or the spray gun. This often results in slight deviations in the coating position and quality, leading to unstable coating quality. Utility Model Content

[0004] The purpose of this invention is to solve various problems of existing spraying devices and to propose a synchronously adjustable double-sided spraying device.

[0005] To achieve the above and other objectives, this utility model proposes a synchronously adjustable double-sided spraying device, comprising: a first rotating shaft assembly, including a first rotating shaft extending along a first direction and a first bevel gear disposed at one end of the first rotating shaft; two second rotating shaft assemblies, each including a second rotating shaft, a second front bevel gear, and a second rear bevel gear, the two second rotating shafts extending along a second direction perpendicular to the first direction, the two second front bevel gears each disposed at one end of the two second rotating shafts and meshing with the first bevel gear, and the two second rear bevel gears... Two screw assemblies are respectively disposed at the other end of the two second rotating shafts and away from the first bevel gear; each screw assembly includes a screw extending along the first direction and a third bevel gear disposed at one end of the screw, the two third bevel gears respectively meshing with the two second rear bevel gears; and two spraying assemblies, each including a platform and a spray gun disposed on the platform, the two screws respectively passing through the two platforms, the two spray guns respectively disposed on the two platforms and facing each other, wherein the rotation of the first rotating shaft drives the two platforms to move synchronously along the first direction.

[0006] Optionally, each of the two screw assemblies also includes a guide rod, which extends along the first direction and passes through the two platforms respectively.

[0007] Optionally, it also includes a conveyor belt for conveying the material along a third direction perpendicular to the first direction and the second direction, the conveyor belt being disposed between the two spraying assemblies.

[0008] Optionally, the first direction is parallel to the direction of gravity.

[0009] Optionally, the two spray guns are positioned facing each other in this second direction.

[0010] Therefore, the synchronously adjustable dual-sided spraying device of this invention allows the platform to rise and fall synchronously, so that the workpiece between the two spray guns can be uniformly sprayed from both sides simultaneously, and the two spray guns always maintain the same height. In this way, it is not necessary for the workpiece and the spray guns to rotate relative to each other, and if fine adjustments to the spraying position are required, the two spray guns moving synchronously in the first direction can provide stable spraying quality and will not cause any difference in the height of the sprayed surface.

However, this description and drawings are only used to illustrate this utility model and are not intended to limit the scope of this utility model in any way. Attached Figure Description

[0039] To fully understand this utility model, the following specific embodiments, in conjunction with the accompanying drawings, will provide a detailed description. Those skilled in the art can understand the purpose, features, and effects of this utility model from the content disclosed in this specification. It should be noted that this utility model can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the inventive point of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustration only and are not depictions based on actual dimensions. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the claims of this utility model. The explanation is as follows:

[0040] like Figure 1 As shown, the synchronously adjustable double-sided spraying device 100 of the first embodiment of the present invention includes: a first rotating shaft group 1, two second rotating shaft groups 2, two screw assemblies 3 and two spraying assemblies 4.

[0041] The first rotating shaft assembly 1 includes a first rotating shaft 11 extending along a first direction d1 and a first bevel gear 12 disposed at one end of the first rotating shaft 11.

[0042] Each of the two second rotating shaft assemblies 2 includes a second rotating shaft 22, a second front bevel gear 21, and a second rear bevel gear 23. The two second rotating shafts 22 extend along a second direction d2 perpendicular to the first direction d1, meaning both second rotating shafts 22 are perpendicular to the first rotating shaft 11. The two second front bevel gears 21 are each disposed at one end of the two second rotating shafts 22 and mesh with the first bevel gear 12. Preferably, the two second front bevel gears 21 are located on opposite sides of the first bevel gear 12, causing the two second rotating shafts 22 to extend in opposite directions. The two second rear bevel gears 23 are each disposed at the other end of the two second rotating shafts 22, away from the first bevel gear 12.

[0043] Each of the two screw assemblies 3 includes a screw 32 extending along the first direction d1 and a third bevel gear 31 disposed at one end of the screw 32. The two third bevel gears 31 respectively mesh with the two second rear bevel gears 23.

[0044] Each of the two spraying assemblies 4 includes a platform 41 and a spray gun 42 disposed on the platform 41. Two screws 32 respectively pass through the two platforms 41. When the screws 32 rotate, the corresponding platform 41 is displaced along the axial direction (also the first direction d1) of the screws 32. The two spray guns 42 are each disposed on the two platforms 41 and are arranged facing each other. In this embodiment, the two spray guns 42 are arranged facing each other in the second direction d2. However, the present invention is not limited to this.

[0045] When the platform 41 is displaced along the first direction d1, the spray gun 42 mounted on it also moves. The platform 41 can be any object that provides a mounting surface, and the spray gun 42 is not limited to any form. Various spray guns, nozzles, and other spray nozzles that can provide the function of spraying paint are all considered spray guns 42 as defined in this utility model.

[0046] Please refer to Figure 1 and Figure 2 They respectively explained how the first rotating axis 11 rotates to drive the two platforms 41 to move synchronously along the first direction d1.

[0047] like Figure 1 As shown, the first rotating shaft 11 rotates counterclockwise via a power component (not shown) or by manual rotation, and then sequentially rotates the first bevel gear 12 and the two second front bevel gears 21 to synchronize the rotation of the two second rotating shafts 22. Next, the two second rotating shafts 22 sequentially drive the second rear bevel gear 23 and the third bevel gear 31 to synchronize the rotation of the screws 32 on both sides. The synchronized rotation of the two screws 32 causes the platform 41 to descend synchronously, thus ensuring that the height of the two spray guns 42 remains the same at all times.

[0048] For example Figure 2As shown, the first rotating shaft 11 is rotated clockwise via a power component (not shown) or manually. This rotation, in turn, drives the two second rotating shafts 22 to rotate synchronously via the first bevel gear 12 and the two second front bevel gears 21. The two second rotating shafts 22 then sequentially drive the second rear bevel gear 23 and the third bevel gear 31, respectively, causing the screws 32 on both sides to rotate synchronously. The synchronous rotation of the two screws 32 causes the platform 41 to rise synchronously, thus ensuring that the two spray guns 42 remain at the same height.

[0049] It should be noted that the description of the clockwise and counterclockwise rotation of the first rotating shaft 11 causing the platform 41 to move up and down is merely illustrative. Clockwise rotation does not necessarily mean that the platform 41 rises synchronously, and counterclockwise rotation does not necessarily mean that the platform 41 falls synchronously. Those skilled in the art should understand after reading this utility model that the direction of displacement of the platform 41 can be changed by changing the rotation direction of the first rotating shaft 11, and the amount of displacement of the platform 41 can be adjusted by changing the amount of rotation of the first rotating shaft 11.

[0050] By synchronously raising and lowering the platform 41, the material S (reference) between the two spray guns 42 is positioned... Figure 3 The workpiece S can be evenly sprayed simultaneously from both sides by spray guns 42, and the two spray guns 42 always maintain the same height. In this way, it is not necessary for the workpiece S to rotate relative to the spray guns 42, and the workpiece S itself can be sprayed in a 360-degree direction (each of the two spray guns 42 is responsible for 180 degrees). Furthermore, if fine adjustments to the spraying position are required, the two spray guns 42, which move synchronously in the first direction d1, can provide a stable spraying quality and will not cause any difference in the height of the sprayed surface.

[0051] Furthermore, in this embodiment, each of the two screw assemblies 3 also includes a guide rod 33, which extends along the first direction d1 and passes through the two platforms 41 respectively. That is, the guide rod 33 is parallel to the screw 32, and the main function of the guide rod 33 is to assist the screw 32 so that the platform 41 can move stably.

[0052] Furthermore, in this embodiment, as Figure 4 As shown, the synchronously adjustable double-sided spraying device 100 of this utility model also includes a conveyor belt 5, which conveys the material S along a third direction d3 perpendicular to the first direction d1 and the second direction d2. The conveyor belt 5 is disposed between the two spraying components 4. However, this utility model is not limited to this. The conveying direction of the conveyor belt 5 is not necessarily the third direction d3 perpendicular to the first direction d1 and the second direction d2. Any direction of travel that can pass between the two spray guns 42 can be the conveying direction of the conveyor belt 5.

[0053] Furthermore, in this embodiment, as Figures 1 to 4As shown, the extension direction of the first rotating shaft 11, also known as the first direction d1, is parallel to the direction of gravity. In other words, the plane formed by the second direction d2 and the third direction d3 is a horizontal plane. The spray gun 42 sprays paint in a horizontal direction, and the conveyor belt 5 transports the material S on the horizontal plane. However, this utility model is not limited to this. Figure 5 As shown, in the synchronously adjusted double-sided spraying device 100a of the second embodiment of this utility model, the plane formed by the first direction d1 and the second direction d2 is a horizontal plane. The conveying direction of the conveyor belt (not shown) can be perpendicular to the gravity direction of the first direction d1 and the second direction d2, or it can be as follows: Figure 5 As shown by the swirling arrow, the material S is also conveyed in the first direction d1.

[0054] This utility model has been disclosed above with reference to preferred embodiments. However, those skilled in the art should understand that the embodiments described are merely for illustrating the utility model and should not be construed as limiting its scope. It should be noted that all variations and substitutions equivalent to the described embodiments should be included within the scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
