[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0020] See also Figure 1-3 , as shown in the figure: This embodiment is a preferred implementation of the technical solution, a rotary multi-workpiece batch spraying device, comprising a base plate 1; an annular baffle 3 is fixed on the upper side of the base plate 1, a spraying end 2 is arranged on one side of the annular baffle 3, a plurality of spraying pipes 12 are connected to the spraying end 2, the spraying pipe 12 passes through the annular baffle 3, a rotating frame 13 is arranged inside the annular baffle 3, a workpiece clamp 11 is fixed on the circumference of the rotating frame 13, a coupling 10 is connected to the middle position of the rotating frame 13 via a shaft, and the coupling 10 is connected to the output shaft of the motor 8;

[0021] It should be noted that: in the spraying device involved in the present application, the rotation of the rotating frame 13 is driven by setting a motor 8 and a coupling 10 to achieve position adjustment of the workpieces fixed inside the workpiece clamp 11, and the spraying of the workpieces by the multiple spray tubes 12 can be carried out on multiple workpieces at the same time, and it is convenient to alternately use different coatings to improve the spraying efficiency. In the initial state, the rotating frame 13 is located above the annular baffle 3, and multiple workpieces are clamped and fixed inside the workpiece clamp 11. Then the cylinder 7 is started, and the piston end of the cylinder 7 drives the crossbeam 5 to descend, so that the position of the rotating frame 13 is lowered until the workpiece descends to the spraying position, and the spray end 2 is started. The spray end 2 feeds the spray tube 12, and the spray tube 12 is used to coat the workpiece. Different spray tubes 12 can be filled with different types of coatings. During the rotation of the workpiece, batch spraying is achieved on the one hand, and multi-layer coating is achieved on the other hand.

[0022] Among them Figure 1 and Figure 2As shown, the motor 8 is fixed with a side plate 14 via a bracket 9, a crossbeam 5 is fixed to the side of the side plate 14, the end of the crossbeam 5 is matched with a pillar 4, a cylinder 7 is fixed to the top of the pillar 4, and the piston end of the cylinder 7 penetrates the pillar 4 and connects to the end of the crossbeam 5; the end of the crossbeam 5 is symmetrically provided with grooves, and the grooves are matched with the protrusions on the inner wall of the pillar 4;

[0023] It should be noted that: the side plate 14 and the bracket 9 are used for the installation and fixation of the motor 8, the crossbeam 5 is used for the fixed installation of the side plate 14, and the crossbeam 5 moves up and down under the action of the piston end of the cylinder 7. When the crossbeam 5 is lifted or lowered, it will drive the side plate 14 fixed thereto to rise and fall synchronously, thereby making the motor 8, coupling 10, rotating frame 13 and workpiece clamp 11 rise and fall as a whole, which is used for position adjustment of several workpieces and convenient for taking and placing.

[0024] An air pump 6 is fixed to the upper part of the crossbeam 5, and the air outlet end of the air pump 6 cooperates with the middle cavity of the crossbeam 5. The lower side opening of the crossbeam 5 is located above the workpiece clamp 11;

[0025] It should be noted that the airflow generated by the air pump 6 when it is working is transported to the workpiece clamp 11 through the cavity in the middle of the beam 5, and the workpiece clamped in the workpiece clamp 11 is dried by air blast, thereby accelerating the air drying of the workpiece.

[0026] Among them Figure 3 As shown, the bottom of the rotating frame 13 is movably connected to the bottom plate 1 through the shaft, and the rotating frame 13 and the annular baffle 3 are arranged concentrically; a plurality of workpiece clamps 11 are arranged in an equidistant circular array around the rotating frame 13, and the workpiece clamps 11 are arc-shaped elastic structures;

[0027] It should be noted that the bottom of the rotating frame 13 is separated from the bottom plate 1 to prevent the bottom plate 1 from interfering with the rotation of the rotating frame 13. After the bottom of the rotating frame 13 is movably connected to the bottom plate 1 via the shaft, the bottom plate 1 can balance the rotation of the rotating frame 13 to avoid shaking. The concentric arrangement of the rotating frame 13 and the annular baffle 3 prevents the workpiece frames 11 from colliding with the inner wall of the annular baffle 3 during rotation. The workpiece clamp 11 with an elastic arc structure is convenient for clamping and fixing the sprayed workpiece.
