Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] like Figure 1-Figure 4 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the clamping plate 3 of the spraying device is inconvenient to replace according to the workpiece, which affects the processing efficiency, a disassembly and assembly mechanism is disclosed:

[0032] The device comprises a main body 1, a rotating assembly 2 is connected to the inner side of the main body 1, a clamping plate 3 is connected to the end of the rotating assembly 2, a spray box 4 is connected to the left side of the main body 1, a controller 5 is installed at the front of the main body 1, a sprayer 6 is installed inside the main body 1, a slot 201 is provided at the end of the rotating assembly 2, a first through slot 202 is provided through the side of the rotating assembly 2, a guide block 203 is fixed inside the slot 201, an insertion block 204 is slid through the inside of the first through slot 202, a telescopic slot 205 is symmetrically provided on the side of the insertion block 204, a spring 206 is connected inside the telescopic slot 205, and a telescopic block 207 is connected to the end of the spring 206. A fixed block 208 is fixed to the back of the holding plate 3, and guide grooves 209 are provided on the upper and lower sides of the fixed block 208. A second through-groove 210 is provided on the side of the fixed block 208. A disassembly and assembly mechanism for replacing the clamping plate 3 is provided inside the slot 201. A sliding groove 301 is symmetrically provided on the front of the clamping plate 3. A positioning mechanism for clamping the workpiece is provided inside the sliding groove 301. The guide block 203 and the rotating assembly 2 are an integral structure. The insertion block 204 is slidably connected to the first through-groove 202 and the second through-groove 210.

[0033] When the spraying device needs to replace the clamping plate 3, the telescopic block 207 can be pressed to slide through the telescopic slot 205. When the telescopic block 207 slides, the spring 206 can be squeezed. After the telescopic block 207 is squeezed into the telescopic slot 205, it pushes the insertion block 204.

[0034] Example 2:

[0035] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the clamping plate 3 of the spraying device has low extrusion efficiency and is not stable enough, which affects the spraying quality, a positioning mechanism is disclosed:

[0036] The positioning mechanism includes a first sliding block 302, and the first sliding block 302 slides through one sliding groove 301, and a second sliding block 303 slides through the other sliding groove 301. The first sliding block 302 and the front of the first sliding block 302 are fixed with a connecting block 304, and the surface of the connecting block 304 is connected to an extrusion block 305.

After the workpiece is positioned, it can be sprayed by the sprayer 6, which improves the efficiency of the spraying device in positioning the workpiece.

[0037] Example 3:

[0038] like Figure 2 、 Figure 5 and Figure 7 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the extrusion block 305 of the spraying device is often worn and needs to be replaced, and the replacement takes a lot of time and affects the work efficiency, based on the second embodiment, an extrusion mechanism is disclosed:

[0039] The connecting block 304 is provided with an extrusion mechanism, which includes a positioning groove 310, and the positioning groove 310 is symmetrically opened on the surface of the connecting block 304, and an extrusion groove 311 is symmetrically opened on the inner side of the connecting block 304.

At this time, the extrusion block 305 can be separated from the connecting block 304. After the extrusion block 305 is separated, it can be replaced with a new one, which improves the replacement efficiency of the extrusion block 305 and improves the convenience of using the spraying device.
