[0002] A spray gun mechanism is a device specifically used to convert a liquid (such as paint, coating, adhesive, etc.) or other fluid materials into fine particles and uniformly spray them onto the surface of an object after atomization by a high-speed air flow.

Moreover, it can also spray the workpiece in all directions without dead angles, so that when the spray gun sprays the workpiece, the paint layer can be more uniform, improving the uniformity and overall quality of the coating, enhancing the appearance of the product and its anti-corrosion and protection performance. At the same time, it can also reduce the waste of paint, save resources and reduce production costs. The present utility model drives the spray gun to rotate circumferentially through the driving assembly, realizing spraying on each surface of the workpiece, further improving the working efficiency and making the paint layer of the workpiece more uniform.

[0022] 2. For a spray gun mechanism capable of multi-faceted spraying of the present utility model, by providing two spray guns and two mounting seats, it can enable the two spray guns to operate simultaneously to cover a larger spraying area within a unit time, significantly shortening the spraying cycle and improving the production efficiency. Moreover, when the two spray guns spray, they can more comprehensively and evenly cover the surface of the workpiece with the paint layer, reducing omissions and uneven coating phenomena, ensuring that every corner and edge can be fully sprayed, and improving the overall quality and aesthetics of the coating.

[0023] 3. For a spray gun mechanism capable of multi-faceted spraying of the present utility model, by providing a housing and a base, it can enclose the motor and the mounting frame placed therein, preventing paint or dust from entering the interior of the housing to avoid damaging the motor.

Detailed implementation manners

[0036] In order to better understand the above technical solutions, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.

[0037] Embodiment 1

[0038] As Figures 1-7 shown, a spray gun mechanism capable of multi-sided spraying in this embodiment includes a spray gun 1, a driving assembly 2, a speed reducer 3, and a mounting seat 4.

[0039] Specifically, the output end of the driving component 2 is fixedly connected to the input shaft 31 of the speed reducer 3 through the rotating shaft 5, the mounting seat 4 is fixedly connected to the output shaft 32 of the speed reducer 3, the axis of the output shaft 32 is perpendicular to the axis of the input shaft 31, the spray gun 1 is installed on the mounting seat 4 and the spraying direction of the spray gun 1 is the same as the direction of the axis of the input shaft 31. The output end of the driving component 2 can drive the input shaft 31 to rotate through the rotating shaft 5, and the input shaft 31 can drive the output shaft 32 to rotate, so as to drive the mounting seat 4 to rotate around the axis of the output shaft 32, and further drive the spray gun 1 to rotate circumferentially around the axis of the output shaft 32, so as to spray multiple surfaces of the workpiece. By setting the driving component 2, the speed reducer 3 and the mounting seat 4, it can be realized that the spray gun 1 can rotate circumferentially around the axis of the output shaft 32 along with the mounting seat 4, and further realize spraying on each surface of the workpiece, improving the automation degree and efficiency of the spraying operation, and reducing the need for manual operation. Moreover, it can also spray the workpiece in all directions without dead angles, so that when the spray gun 1 sprays the workpiece, the paint layer can be more uniform, improving the uniformity and overall quality of the coating, and enhancing the appearance and anti-corrosion and protection performance of the product. At the same time, it can also reduce the waste of paint, save resources and reduce the production cost. Preferably, clamping grooves 41 are respectively arranged at both ends of the two mounting seats 4, and the two spray guns 1 are respectively placed in the two clamping grooves 41 and are detachably connected to the mounting seat 4, which can enable the two spray guns 1 to be accurately positioned during installation, and further make the installation of the spray gun 1 and the mounting seat 4 more stable and more accurate during spraying.

[0040] Furthermore, both ends of the output shaft 32 pass through the two side walls of the speed reducer 3. There are two spray guns 1 and two mounting seats 4. The two mounting seats 4 are fixedly connected to both ends of the output shaft 32, and the two spray guns 1 are symmetrically installed on the two mounting seats 4, that is, the two spray guns 1 are symmetrically installed on the two mounting seats 4 with the axis of the input shaft 31 as the mirror symmetry axis, so that the two spray guns 1 can simultaneously spray multiple surfaces of at least one workpiece, thereby realizing the simultaneous operation of the two spray guns 1, so as to cover a larger spraying area per unit time, significantly shorten the spraying cycle and improve the production efficiency. Moreover, when the two spray guns 1 are spraying, they can also cover the surface of the workpiece more comprehensively and evenly, reduce omission and uneven coating phenomena, ensure that every corner and edge can be fully sprayed, and improve the overall quality and aesthetic degree of the coating.

[0041] Preferably, the drive assembly 2 includes a housing 21, a base 22, a motor 23 and a mounting frame 24. The bottom of the housing 21 is detachably connected to the top of the base 22, and the motor 23 and the mounting frame 24 are both located inside the housing 21. The housing 21 and the base 22 can be closed relative to the motor 23 and the mounting frame 24 placed therein, so as to prevent paint or dust from entering the interior of the housing 21, so as not to damage the motor 23. By providing the motor 23, it can provide power to the input shaft 31 so that the mounting seat 4 drives the spray gun 1 to rotate. The base 22 is detachably connected to the mounting frame 24, and the motor 23 is detachably connected to the reducer 3 through the mounting frame 24, and the rotating shaft 5 is located in the mounting frame 24. The mounting frame 24 can fix the motor 23 and the reducer 3 to make the structure of the drive assembly 2 more stable.

[0042] Further, the spray gun mechanism also includes an electric eye sensor 6 and a mounting block 7. One side wall of the mounting block 7 is detachably mounted on one side outer wall of the reducer 3, there is a gap between the mounting block 7 and the mounting seat 4, the electric eye sensor 6 is mounted on the mounting block 7 and the axis of the electric eye sensor 6 is parallel to the axis of the input shaft 31. The electric eye sensor 6 preferably passes through the mounting block 7 and is inserted on the mounting block 7. The mounting seat 4 is detachably connected by a bolt 8, the axis of the bolt 8 is the same as the axis of the electric eye sensor 6 in the initial state and there is a gap between the electric eye sensor 6 and the bolt 8. The electric eye sensor 6 can detect the position of the bolt 8. By setting the electric eye sensor 6 and the mounting block 7, the mounting block 7 can fix the electric eye sensor 6 so that the electric eye sensor 6 can be more stable. And, after the painting is completed, since the mounting seat 4 is detachably connected by the bolt 8, the electric eye sensor 6 can emit light, thereby detecting whether the axis of the bolt 8 is the same as the light, thereby determining whether the position of the mounting seat 4 returns to the initial position.

[0043] Further, the mounting block 7 is a Y-shaped structure arranged horizontally, the opening of the Y-shaped structure faces the mounting seat 4, and the axis of the electric eye sensor 6 is the same as the horizontal center line of the Y-shaped structure. A stopper 9 is detachably mounted on the outer wall of the mounting seat 4, and the stopper 9 can respectively abut against the top walls of the two oblique sides of the Y-shaped structure as the mounting seat 4 rotates, so as to limit the rotation range of the mounting seat 4. When the mounting seat 4 drives the spray gun 1 to rotate to the position where the spray direction of the spray gun 1 faces the rear, the stopper 9 abuts against one of the oblique sides of the Y-shaped structure, thereby avoiding the spray direction of the spray gun 1 facing the rear, and avoiding harm to the operator. Preferably, the opening of the Y-shaped structure is a first arc-shaped structure, and the outer wall of the mounting seat 4 is a second arc-shaped structure. The concave part of the first arc-shaped structure faces the direction away from the mounting seat 4, which can form a clearance area with the first arc-shaped structure, avoiding interference between the mounting seat 4 and the mounting block 7 when rotating, and avoiding damage to the spraying mechanism.

[0044] Further, the speed reducer 3 includes a housing 33, a worm wheel 34 and a worm 35. The worm wheel 34 and the worm 35 are both installed inside the housing 33 and the worm wheel 34 meshes with the worm 35. One end of the worm 35 is connected to the input shaft 31, and the other end is rotatably connected to the inner wall of the housing 33. The axis of the worm 35 is the same as that of the input shaft 31 and the worm wheel 34 is located above the worm 35. The worm wheel 34 is sleeved on the outer wall of the output shaft 32 so that the worm wheel 34 can drive the output shaft 32 to rotate synchronously. By providing the worm wheel 34 and the worm 35, it can effectively convert the high-speed rotation of the motor 23 into the low-speed and high-torque output of the worm 35, reducing the rotational speed of the output shaft 32, so that the spray gun 1 rotates slowly, thereby achieving a large load drive with a small power input and improving the energy utilization rate. One side wall of the housing 33 facing the rotating shaft 5 is connected to the mounting frame 24. An opening is provided on one side wall of the housing 33 facing the rotating shaft 5, and one end of the worm 35 connected to the rotating shaft 5 is located in the opening and there is a gap between it and the side wall of the housing 33 close to the rotating shaft 5. By providing the housing 33, it can enclose the worm wheel 34 and the worm 35, prevent dust from entering the speed reducer 3, and prevent the speed reducer 3 from getting stuck. Preferably, the speed reducer 3 further includes two bearings 36. The two bearings 36 are both placed inside the housing 33 and sleeved on the output shaft 32, which can ensure that the output shaft 32 remains stable during rotation, reduce vibration, and improve the accuracy and quality of the spraying operation.

[0045] Further, the ratio of the number of teeth of the worm wheel 34 to the number of heads of the worm 35 is 30:1, which realizes a reduction ratio of 30:1 for the speed reducer 3. Thus, after the output rotational speed of the motor 23 is reduced by the worm wheel 34 and the worm 35, the rotational speed output by the output shaft 32 is 1 / 30 of the output rotational speed of the motor 23, so that the spray gun 1 rotates slowly, increasing the torque during its rotation and making the spray gun 1 more stable during rotation.

[0046] With the above structure, the working principle of a spray gun mechanism capable of multi-faceted spraying in this embodiment is as follows:

[0047] As Figure 1 shown, first assemble the spray gun mechanism. After assembly, place the spray gun mechanism in the spraying chamber to prepare for spraying the workpiece. In addition, when the spray gun 1 is in the initial position, the axis of the electric eye sensor 6 is the same as the axis of the bolt 8.

[0048] The operator checks the spray gun mechanism. After confirming that there is no problem, the operator simultaneously drives the two spray guns 1 to spray the coating. Then, the driving motor 23 rotates, driving the rotating shaft 5 to rotate, which in turn drives the input shaft 31 to rotate. The input shaft 31 drives the worm 35 to rotate, thereby driving the worm gear 34 to rotate. The worm gear 34 drives the bearing 36 and the output shaft 32 to rotate synchronously with the worm gear 34, thereby driving the mounting seat 4 to rotate, and further driving the spray gun 1 to rotate circumferentially around the axis of the output shaft 32, so as to realize spraying on multiple surfaces of the workpiece. When the gun head of the spray gun 1 is about to rotate towards the operator, the stop block 9 abuts against the end of one of the hypotenuses of the mounting block 7, thereby preventing the spray gun 1 from rotating again.

[0049] After spraying is completed, the driving motor 23 rotates, driving the rotating shaft 5 to rotate, which in turn drives the input shaft 31 to rotate. The input shaft 31 drives the worm 35 to rotate, thereby driving the worm gear 34 to rotate. The worm gear 34 drives the bearing 36 and the output shaft 32 to rotate synchronously with the worm gear 34, thereby driving the mounting seat 4 to rotate, and further driving the spray gun 1 to rotate circumferentially around the axis of the output shaft 32 to the initial position. The electric eye sensor 6 emits light to detect the bolt 8. When the electric eye sensor 6 detects that the axis of the bolt 8 is the same as the axis of the electric eye sensor 6, it is determined that the spray gun 1 has returned to the initial position, and spraying can be stopped at this time.
