Including air spraying, airless spraying, electrostatic spraying and other methods. In order to avoid polluting the environment, spraying is generally carried out in a spray room, and the nozzles are mostly fixed. However, the shape of the workpiece is irregular, and the fixed nozzle can only spray from a fixed angle, which makes it difficult to fully cover all parts of the workpiece, and easily leads to uneven spraying effect. In response to the emergence of the above problems, the existing technology has not solved them well, which has brought troubles to the normal work in this field. Therefore, there is an urgent need for a spray conveying device to solve the above problems. Utility Model Content

[0026] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] Reference Figures 1 to 3 , which is the first embodiment of the present utility model, proposes a spraying and conveying device, including a frame 1, a spraying room 2, a track 3, a mobile frame 4, a hanging frame 5, a torsion gear 6 and a torsion rack 7, wherein the track 3 is arranged on the frame 1, the track 3 passes through the spraying room 2, the mobile frame 4 is movably arranged relative to the track 3, the hanging frame 5 is rotatably arranged on the mobile frame 4, the torsion gear 6 is fixed on the hanging frame 5, the torsion rack 7 is arranged in the spraying room 2, there are multiple torsion racks 7, and the torsion racks 7 are distributed on both sides of the torsion gear 6, and the multiple torsion racks 7 on both sides of the torsion gear 6 are staggered.

[0028] In this embodiment, track 3 is suspended from frame 1 and extends through the spray booth. A mobile frame 4 is arranged to move relative to track 3, facilitating the transport of workpieces into the spray booth. To ensure uniform spray coating of all parts of the workpiece, a hoisting frame 5 is pivoted on mobile frame 4, allowing the workpiece to be twisted within the spray booth, resulting in uniform spray coating of all parts.

[0029] Specifically, the rotation of the hoist frame 5 is achieved by a torsion gear 6 and a torsion rack 7. The torsion gear 6 is fixed to the hoist frame 5 and is coaxial with the rotation axis of the hoist frame 5. The torsion rack 7 is installed in the spray booth and is located in the travel path of the torsion gear 6. Multiple torsion racks 7 are installed on both sides of the hoist frame 5, and the torsion racks 7 on both sides are staggered. This ensures that the torsion gear 6 only meshes with one torsion rack 7 at a time, avoiding the problem of gear tooth interference damage.

[0030] When the hoisting frame 5 drives the torsion gear 6 to move, it first engages with the torsion rack 7 on one side, causing the torsion gear 6 to rotate, causing the hoisting frame 5 and the workpiece to produce an angular twist. As the hoisting frame 5 continues to move, the torsion gear 6 engages with the torsion rack 7 on the other side, causing the hoisting frame 5 and the workpiece to produce an angular twist in the opposite direction. As the hoisting frame 5 moves within the spray booth, it alternates between multiple forward and reverse angular twists, allowing the workpiece to be more fully oriented in the spray direction, achieving a uniform spray effect.

[0031] It also includes a supporting plate 8, a horizontal bar 9 and a universal wheel 10. The supporting plate 8 is arranged in the spray room 2, the horizontal bar 9 is arranged on the hanging frame 5, and the hanging frame 5 has the horizontal bar 9 on both sides. The universal wheel 10 is installed on the horizontal bar 9. There are multiple universal wheels 10, which are evenly distributed along the length direction of the horizontal bar 9. The universal wheel 10 is used to abut the supporting plate 8.

[0032] In this embodiment, to ensure the stability of the hoisting frame 5 and the workpiece during twisting, horizontal bars 9 are provided on both sides of the hoisting frame 5. Multiple universal wheels 10 are mounted on the horizontal bars 9, and corresponding support plates 8 are provided in the spray booth. When the hoisting frame 5 moves, the universal wheels 10 roll on the support bars. The abutment between the universal wheels 10 and the support plates 8 not only improves the stability of the movement of the hoisting frame 5, but also helps to distribute the weight borne by the hoisting frame 5, thereby ensuring the service life of the hoisting frame 5. When the hoisting frame 5 is twisted, the horizontal bars 9 will also twist. At this time, the universal rolling characteristics of the universal wheels 10 can ensure that they can always roll on the support plates 8.

[0033] It also includes a lifting hook 11, both ends of the lifting hook 11 have hook-shaped parts, the top of the lifting hook 11 is used to hook on the lifting frame 5, and the bottom of the lifting hook 11 is used to hook the workpiece.

[0034] The lifting hook 11 includes a first section 12 and a second section 13 . The first section 12 is slidably disposed on the second section 13 to adjust the overall length of the lifting hook 11 .

[0035] The first section 12 and the second section 13 are both provided with a plurality of pin holes 14 along the length direction, and also include a fixing pin 15, which passes through the pin holes 14 on the first section 12 and the second section 13 at the same time to fix the first section 12 and the second section 13.

[0036] In this embodiment, the lifting hook 11 includes a first section 12 and a second section 13 from top to bottom. The top of the first section 12 has a hook-shaped portion for hooking on the lifting frame 5, and the bottom of the second section 13 also has a hook-shaped portion for hooking the workpiece. The second section 13 is provided with an axial insertion hole, and the first section 12 is slidably set in the insertion hole. After the first section 12 and the second section 13 slide relative to each other, the overall length of the lifting hook 11 can be adjusted. In order to achieve the positioning of the first section 12 and the second section 13 after sliding, a plurality of pin holes 14 are provided on the first section 12 and the second section 13 along the length direction. The positioning connection between the two can be achieved by simultaneously passing the fixing pin 15 through the pin holes 14 on the first section 12 and the second section 13, so as to achieve flexible adjustment of the length of the lifting hook 11, thereby better adapting to workpieces of different lengths.

[0037] It also includes a stabilizing limit plate 16 , which is arranged on the hanging frame 5 . There are two stabilizing limit plates 16 , which are respectively located on both sides of the first section 12 to limit the shaking space of the first section 12 .

[0038] A flexible buffer layer is provided on the surface of the stabilizing limit plate 16 facing the first section 12 .

[0039] In this embodiment, when the hanging frame 5 is twisted at an angle, the hook-shaped portion at the top of the first section 12 may shake due to inertia, which is not conducive to the stability of the workpiece. To this end, two stabilizing limit plates 16 are provided on the bottom surface of the hanging frame 5. The hook-shaped portion at the top of the first section 12 is located between the two stabilizing limit plates 16. When twisting occurs, it will abut against the stabilizing limit plates 16. In order to prevent the impact caused by the abutment from damaging the hanging hook 11, a flexible buffer layer is also provided on the surface of the stabilizing limit plate 16, preferably a rubber layer, which can effectively absorb the impact force generated by the abutment and play a good buffering role.

[0040] The movable frame 4 further includes a roller 17 , which is rotatably mounted on the movable frame 4 and abuts against the surface of the track 3 .

[0041] The surface of the roller 17 has a flexible barrier layer.

[0042] In this embodiment, a roller 17 is rotatably provided on the mobile frame 4, and the roller 17 rolls on the track 3 to achieve stable movement of the mobile frame 4. A flexible interlayer is provided on the surface of the roller 17. The interlayer is preferably a rubber layer, which can increase friction and improve stability during movement. At the same time, it can also effectively reduce the noise generated during rolling.

[0043] It also includes an exhaust gas treatment box 18, which is connected to the spray booth 2 through a pipeline.

[0044] In this embodiment, the exhaust gas in the spray booth 2 can be sucked into the exhaust gas treatment box 18 through a pipeline to purify the gas, thereby improving the paint mist phenomenon and preventing the exhaust gas from diffusing out of the spray booth and causing damage to the environment and human body.
