TECHNICAL FIELD

[0001] The present application relates to the technical field of paint spraying hangers, and particularly relates to a hanger for batch paint spraying of horn mesh with adjustable spacing. BACKGROUND

[0002] In the process of batch paint spraying of horn mesh, a hanger is an indispensable auxiliary tool, which mainly functions to realize the suspension and positioning of the horn mesh, ensure that the workpiece surface can be uniformly stressed and fully contacted with paint mist during paint spraying, and avoid the horn mesh surface from being scratched and polluted by contacting other objects.

[0003] However, the spacing of the existing hanger for batch paint spraying of horn mesh is fixed, and the hanger has poor versatility. Since horn meshes of different models and specifications have great differences in size, the spacing between the suspension stations of the existing hanger is mostly fixed, and the hanger can only be adapted to a single specification or a few similar specifications of horn mesh. When different specifications of horn mesh need to be switched, the corresponding special hanger must be replaced, which increases the cost of tool manufacturing and is difficult to meet the flexible production requirements of multiple varieties and small batches.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with specific embodiments.

[0028] Embodiments

[0029] Reference Figures 1-7 In the present embodiment, a horn mesh batch paint spraying hanger with adjustable spacing is proposed, which comprises a base 1 in disc structure and a support column 2 fixedly installed on the base 1, a plurality of hanging rings 3 arranged in layers from top to bottom are sleeved on the outer side of the support column 2, the bottom of the hanging ring 3 is provided with an annular spacing adjusting mechanism, and the bottom of the hanging ring 3 is movably installed with a plurality of hooks 4 for batch paint spraying of horn mesh through the annular spacing adjusting mechanism.

[0030] The connecting frame 304 is further fixedly connected between the inner walls of the two sides of the hanging ring 3, the connecting frame 304 is provided with an up-down spacing adjusting mechanism, and the connecting frame 304 is movably sleeved on the support column 2 through the lower spacing adjusting mechanism.

[0031] The annular spacing adjusting mechanism comprises an annular adjusting cavity 301 arranged at the bottom of the hanging ring 3, a plurality of arc-shaped adjusting blocks 7 movably arranged along an annular track in the annular adjusting cavity 301, and the bottom of the arc-shaped adjusting block 7 extends below the annular adjusting cavity 301 and is fixedly connected with the top end of the hook 4.

[0032] The bottom inner wall of the annular adjusting cavity 301 is provided with an annular through groove 302, and the arc-shaped adjusting block 7 slides through the annular through groove 302 along the annular track.

[0033] The up-down spacing adjusting mechanism comprises a sleeving cavity 306 arranged on the connecting frame 304, and a lifting shell 11 fixedly arranged in the sleeving cavity 306.

[0034] The lifting shell 11 has a rotating seat 1101 on the left inner wall, and the left end of the worm gear 1103 is rotatably mounted on the rotating seat 1101; the support column 2 has multiple inclined bracing rods 101 fixedly connected to its circumferential bottom side, and the inclined bottom end of the bracing rod 101 is fixedly connected to the top surface of the base 1.

[0035] The base 1 is also equipped with an electrical control box 12, which contains a controller that is electrically connected to the stepper motor 1102.

[0036] like Figures 1-7 As shown, this adjustable-spacing speaker grille batch painting hanger, in use, utilizes layered hanging rings 3 and multiple hooks 4 arranged in a ring on the bottom side of the hanging rings 3, allowing for batch painting and hanging of multiple speaker grilles at once. Furthermore, the spacing of the hooks 4 can be adjusted according to actual conditions during hanging. During adjustment: the collar 5 in the ring spacing adjustment mechanism pulls down the pull rod 6 and the positioning teeth 8, releasing the engagement of the positioning teeth 8 with the positioning groove 303. Simultaneously, the downward pull of the positioning teeth 8 compresses the positioning spring 9. Subsequently, the collar 5, through the pull rod 6 and the positioning teeth 8, drives the arc-shaped adjustment block 7 to move along a ring trajectory within the ring adjustment cavity 301. The arc-shaped adjustment block 7 then moves the hooks 4, thus adjusting the spacing of the hooks 4 on the bottom side of the same layer of hanging rings 3 along a ring direction. After adjustment, the collar 5 is released, and under the reset action of the positioning spring 9, the positioning teeth 8 engage with the positioning groove 303, completing the adjustment. Simultaneously, the stepper motor 1102 in the vertical spacing adjustment mechanism can drive the worm gear 1103 to work in both forward and reverse directions. The worm gear 1103 meshes with the worm wheel 1104, which can drive the solenoid tube 1105 to rotate on the bearing 1106. This allows the lifting shell 11 to be driven upward or downward along the screw 10 via the solenoid tube 1105 on the bearing 1106. The lifting shell 11 then drives the connecting frame 304, the hanging ring 3, and the hook 4 to be raised and lowered as a whole, thereby adjusting the vertical spacing of the hook 4 on the bottom side of the hanging ring 3. Furthermore, the stepper motor 1102 on each connecting frame 304 can work independently, thus adjusting the vertical spacing of the hanging ring 3 and hook 4 between each layer. Ultimately, this invention allows for adjustment not only of the vertical spacing of the hooks 4 but also of the circumferential spacing of the hooks 4, resulting in a wider adjustment range and better performance. This avoids the situation where existing speaker grille painting hangers, due to their fixed spacing, struggle to accommodate different specifications of speaker grilles. By designing the hooks 4 with adjustable circumferential and vertical spacing, this invention better adapts to the painting and hanging needs of various speaker grille specifications, improving flexibility in use and greatly satisfying user needs.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
