[0030] Referring to Figures 1-2 , the present application is a paint spraying device for valve machining, which comprises an annular track 1 composed of an inner ring body and an outer ring body, and a sliding block moving along the annular track 1. A fixing frame 3 for carrying a valve 10 is welded on the sliding block during use. When spraying paint, the valve 10 can be directly placed on the fixing frame 3. At this time, when the sliding block moves along the annular track 1, the valve 10 moves synchronously.

The first paint spraying channels and the second paint spraying channels each comprise a U-shaped cover 2 covering the annular track 1. The first paint spraying channels and the second paint spraying channels are structurally identical, and are sequentially provided with a paint spraying section and a hot air drying section along the moving direction of the sliding block. The first paint spraying channels and the second paint spraying channels form an operator station and a cooling station therebetween.

[0032] When used, the valve 10 is installed on the fixing frame 3 at the operation station, at this time, the fixing frame 3 is moved into the first paint spraying channel to spray primer and dry; after drying, it is naturally cooled at the open cooling station, and then it is sprayed with topcoat and dried at the second paint spraying channel, and finally it is moved to the operation station, at this time, the valve 10 is detached from the fixing frame 3.

[0033] On the basis of the above-mentioned embodiment 1, the hot air drying section includes a first drying section with a wind speed of 0.75 m / s and a second drying section with a wind speed of 1.2 m / s, and the hot air drying section has a hot air temperature of 60℃; the low wind speed drying is used first to avoid the paint on the surface of the valve 10 from fluctuating due to too fast wind speed, and after drying through the first drying section, the paint on the surface of the valve 10 slightly condenses, at this time, the high wind speed hot air is used for drying, and the drying speed is improved.

[0034] In embodiment 2, the application further provides a fixing frame 3, which includes a telescopic support inserted into the valve cavity of the valve 10 and abutting against the inner wall of the valve cavity; when used, the telescopic support is inserted into the valve cavity of the valve 10 and abuts against the inner wall of the valve cavity to complete the fixing.

[0035] Specifically, the fixing frame 3 includes a base 30 connected to the sliding block, a column 32 is arranged at the center of the upper surface of the base 30, three groups of telescopic mechanism groups abutting against the inner wall of the valve cavity are arranged on the circumference of the column 32 along the length direction of the column 32, and each telescopic mechanism group includes four telescopic mechanisms 33; a supporting structure 31 supporting the valve 10 is arranged on the circumference of the column 32; when used, the valve 10 is placed on the supporting structure 31, at this time, the telescopic support is inserted into the valve cavity of the valve 10, and the end of the telescopic mechanism 33 abuts against the inner wall of the valve cavity of the valve 10.

[0036] On the basis of the above, the support structure 31 includes four telescopic modules arranged on the upper surface of the base 30 around the column 32, and the end of the telescopic module is provided with a support ring 306; at the same time, the telescopic module includes a piston cavity A302 recessed on the upper surface of the base 30, and a piston column 305 is connected in the piston cavity A302 through a spring A304, and the top end of the piston column 305 is connected with the support ring 306; the column 32 is provided with a main air duct 321 along the length direction thereof, and a plurality of branch air ducts 322, and the telescopic mechanism 33 includes an outer sleeve tube 331 in communication with the branch air duct 322, the outer sleeve tube 331 is provided with a convex ring 323, the convex ring 323 is connected with an inner sleeve rod 332 through a spring B334, and the end of the inner sleeve rod 332 is connected with an abutting head 333; the base 30 is internally formed with an air path 303 in communication with the main air duct 321, and through the above arrangement, when the valve 10 is placed on the support structure 31, that is, under the action of the gravity of the valve 10 itself, the spring A304 is compressed, at this time, the gas in the original piston cavity A302 will enter the inside of the outer sleeve tube 331 along the air path 303, the main air duct 321 and the branch air duct 322, that is, at this time, the spring B334 will be stretched out, thereby driving the inner sleeve rod 332 to move outward, and finally driving the spherical surface of the abutting head 333 to abut against the inner wall of the valve cavity of the valve 10, thereby completing the support and fixation of the valve 10, and avoiding the shaking phenomenon caused by the impact of paint and wind during the paint spraying and drying process of the valve 10.

[0037] On the basis of the above, the upper surface of the base 30 around the column 32 is provided with an annular groove A301a and an annular groove B301b, and the telescopic module is located on the upper surface of the base 30 between the annular groove A301a and the annular groove B301b; the inner and outer edges of the support ring 306 are respectively provided with a flange A307 and a flange B308 inserted into the annular groove A301a and the annular groove B301b, and through the arrangement of the flange A307 and the flange B308, the telescopic module is protected, and the paint is prevented from being blocked at the port of the piston cavity A302.

[0038] On the basis of the above, the flange A307 and the flange B308 both protrude from the upper surface of the support ring 306 to form a limiting part, which limits the position of the valve 10 initially placed on the support ring 306, and avoids the initial position of the valve 10 from being too deviated.

[0040] At the same time, when the valve 10 is taken out, the spring A 304 and the spring B 334 return to the initial position, and at the same time, under the action of the damping block 356, the spring C 353 returns to the initial position, that is, the sealing plate 354 abuts on the sealing ring 351.

[0041] In the application, the damping block 356 slides along the inner wall of the passage 35, and a ventilation hole 357 is arranged along the length direction of the passage 35.
