Detailed Implementation

[0029] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Example 1:

[0031] like Figures 1-5 As shown, the automotive parts surface spraying and drying equipment includes a spraying and drying chamber 100. A partition 101 is fixed in the middle of the inner wall of the spraying and drying chamber 100. The upper side of the partition 101 is configured as a spraying chamber 102, and the lower side of the partition 101 is configured as a storage chamber 103. A plunger pump 104 is placed at the rear end of the spraying and drying chamber 100. An input pipe 105 is connected between the plunger pump 104 and the storage chamber 103. A conveying trough 106 is opened inside the upper side of the spraying and drying chamber 100. An output pipe 107 is provided between the rear end of the spraying and drying chamber 100 and the plunger pump 104, and the output pipe 107 is connected to one end of the conveying trough 106. A spray plate 108 is fixed in the inner wall of the spraying and drying chamber 100. The interior of the spray plate 108 is connected to the other end of the conveying trough 106. Several nozzles 109 are provided on the outer side of the spray plate 108. A rotating assembly is provided between the partition 101 and the conveying trough 106.

[0032] The rotating assembly includes a rotating ring 200, an installation cavity 201 inside a partition 101, a through groove 202 penetrating the installation cavity 201 at the upper end of the partition 101, the rotating ring 200 being located inside the installation cavity 201, a wire mesh 203 being provided on the inner wall of the rotating ring 200, a toothed ring 204 being fixed on the upper outer side of the rotating ring 200, a rotating rod 205 being rotatably mounted at the bottom of the installation cavity 201, one end of the rotating rod 205 penetrating the upper wall of the spray drying oven 100 and extending into the material conveying trough 106, a number of gear teeth 206 matching the toothed ring 204 being provided on the lower outer side of the rotating rod 205, a number of circumferentially distributed pusher blades 207 being fixed on the upper outer side of the rotating rod 205, and each pusher blade 207 being able to slide against the inner wall of the material conveying trough 106, and a guide block 208 being provided on the inner wall of the output pipe 107 near the pusher blades 207.

[0033] The partition plate 101 divides the inside of the spray drying box 100 into two parts, the upper part is the spray cavity 102 which can be used for spraying automobile parts, and the lower part is the storage cavity 103 which is convenient for storing paint for subsequent use; the plunger pump 104 provides power, which can make the paint flow out of the storage cavity 103, and then pass through the input pipe 105, the plunger pump 104, the output pipe 107, the conveying groove 106 and the spray plate 108, and finally make the paint sprayed from each spray head 109, so as to spray the automobile parts;

[0034] Wherein, the through slot 202 is provided, so that the upper and lower sides of the partition plate 101 are communicated, which is convenient for installing the rotating ring 200 between the partition plate 101; the steel wire mesh 203 not only facilitates the placement of automobile parts, but also facilitates the falling of excess paint into the storage cavity 103; the paint delivered by the output pipe 107 can drive each pushing blade 207 to rotate around the rotating rod 205, and the rotating rod 205 can drive each gear tooth 206 to rotate, since any gear tooth 206 and the gear ring 204 are engaged with each other, so the gear tooth 206 can drive the gear ring 204 to rotate, thereby indirectly rotating the rotating ring 200, the steel wire mesh 203 and the automobile parts, so that the spraying operation in each direction of the automobile parts can be realized, and the automobile parts are sprayed more uniformly;

[0035] Wherein, before the paint delivered by the output pipe 107 enters the conveying groove 106, the paint will first contact the guide block, and the guide block occupies half of the internal space of the output pipe 107, so that the delivered paint can pass through the other half of the internal space of the output pipe 107, so that the paint can drive each pushing blade 207 to rotate around the rotating rod 205, thereby indirectly driving the rotating ring 200 to rotate, and further driving the automobile parts to rotate.

[0036] Initially: the staff directly places the automobile parts to be processed on the upper end of the steel wire mesh 203, and then closes the spray drying box 100;

[0037] When the automobile parts are processed: start the plunger pump 104, the plunger pump 104 draws the paint in the storage cavity 103 through the input pipe 105, in this process, the paint is delivered to the inside of the spray plate 108 through the output pipe 107 and the conveying groove 106, and finally sprayed from each spray head 109, so that the automobile parts can be processed;

[0038] During the process of the paint flowing from the output pipe 107 into the conveying trough 106, the paint will push the pusher blades 207 to rotate around the rotating rod 205 because the outer side of each pusher blade 207 abuts against the inner wall of the output pipe 107. The rotating rod 205 indirectly drives each gear 206 to rotate. Since the gear 206 meshes with the gear ring 204, the gear 206 can drive the gear ring 204 to rotate. The gear ring 204 then drives the rotating ring 200 to rotate. The rotating ring 200 drives the wire mesh 203 and the car parts to rotate synchronously. In this way, the car parts can be fully sprayed, thereby improving the quality of the car parts processing.

[0039] In this embodiment, the paint in the storage chamber is drawn by starting the plunger pump and sent to the spray plate through the input pipe, output pipe and conveying trough. It is then sprayed out from the nozzle to process the parts. At the same time, the paint pushes the pusher blade in the output pipe to rotate around the rotating rod. The rotating rod drives the gear teeth, and the gear teeth mesh with the gear ring to make the rotating ring rotate. This, in turn, drives the wire mesh to rotate synchronously with the parts, so as to achieve full spraying and improve the processing quality.

[0040] Example 2:

[0041] like Figures 2-7 As shown, based on Embodiment 1, other components of the automotive parts surface spraying and drying equipment are further described. A limiting ring 300 is fixed to the inner wall of the upper through groove 202, and the limiting ring 300 abuts against the inner wall of the rotating ring 200.

[0042] The front end of the spray drying oven 100 is hinged and sealed with a door 301, and the center of the door 301 is made transparent.

[0043] The lower rear side of the partition 101 is provided with a forward-inclined slide plate 302. A guide plate 303 is fixed between the front end of the slide plate 302 and the inner wall of the spray drying box 100. A leakage port 304 communicating with the storage chamber 103 is opened at the upper end of the guide plate 303.

[0044] The front end of the spray drying oven 100 is provided with a conveying pipe 305 that communicates with the storage chamber 103, and the rear end of the spray drying oven 100 is provided with a discharge pipe 306 that communicates with the storage chamber 103.

[0045] The spray drying oven 100 is equipped with an oven 307 at the left end. An air duct 308 is connected between the oven 307 and the spraying chamber 102. A heat dissipation hole 309 connected to the spraying chamber 102 is opened on the upper right side of the spray drying oven 100. A filter assembly is provided at the front end of the spray drying oven 100, and the filter assembly is located between the spraying chamber 102 and the heat dissipation hole 309.

[0046] In this embodiment, when the rotating ring 200 is installed inside the installation cavity 201, the limiting ring 300 can limit the inner wall of the rotating ring 200, which can prevent the rotating ring 200 from shaking inside the installation cavity 201, thereby affecting the paint falling through the steel mesh 203 into the storage cavity 103 for storage, and further reducing the waste of paint.

[0047] When spraying the automobile parts, the box door 301 needs to be closed, which can prevent harmful gas from escaping during the spraying process, thereby polluting the working environment and affecting the health of the workers.

[0048] Among them, the center part of the box door 301 has a transparent area, which can facilitate the workers to observe the spraying condition of the automobile parts through the transparent area, so as to make real-time adjustment.

[0049] The inclined sliding plate 302 can make the dripping paint slide down, and after accumulating on the upper surface of the deflector 303, the paint can be discharged from the leakage port 304 into the storage cavity 103 for storage, facilitating the subsequent use of the paint. At the same time, the sliding plate 302 can also isolate the hot air in the spraying cavity 102 from directly entering the storage cavity 103, thereby reducing the influence on the paint.

[0050] The material conveying pipe 305 can inject new paint into the storage cavity 103, and the material discharging pipe 306 can discharge the waste paint in the storage cavity 103, so that the workers can more conveniently replace the paint in the storage cavity 103.

[0051] The oven 307 can absorb external air and heat, and then guide the heated air into the spraying cavity 102 through the air conveying pipe 308, so that the automobile parts in the spraying cavity 102 can be dried, thereby improving the efficiency of automobile part processing.

[0052] Among them, after the hot air enters the spraying cavity 102, it will first dry the automobile parts, and then the hot air will carry the harmful gas generated during spraying out of the heat dissipation hole 309.

[0053] Among them, during the process of the hot air carrying the harmful gas from the spraying cavity 102 to the outside, it will enter the filter assembly, which can handle the harmful gas in the hot air, prevent pollution of the environment, and affect the health of the workers.

[0054] The above examples only illustrate the principles and effects of the present application, and are not intended to limit the present application. Any person skilled in the art can modify or change the above examples without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed by the present application shall be covered by the claims of the present application.
