Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a spraying device for centrifuge shells. Background Technology

[0002] As a critical component of precision equipment, the quality of the surface coating on the centrifuge casing directly affects the overall performance and lifespan of the equipment. An ideal surface coating requires high uniformity, excellent corrosion resistance, and consistent appearance. A highly uniform coating not only ensures balanced stress distribution during operation, reducing the risk of damage due to stress concentration, but also improves the equipment's sealing performance and operating efficiency. Furthermore, considering that centrifuges may be used in harsh environments, a corrosion-resistant coating effectively resists chemical corrosion, extending the equipment's lifespan and reducing maintenance costs.

[0003] Traditional single-station spraying or fixed-nozzle designs, due to their fixed nozzle coverage, are difficult to adapt to the spraying needs of centrifuge shells of different sizes, resulting in uneven coating thickness distribution. Often, multiple spraying operations are required to achieve the desired coating effect, which greatly reduces production efficiency. Existing clamping devices mostly use mechanical rigid structures, which can easily damage the surface during the process of fixing the centrifuge shell, affecting product quality. During spraying operations, splashed paint can easily contaminate the work area, increasing cleaning costs and time consumption. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a centrifuge shell spraying device.

[0005] A centrifuge casing spraying device includes a mounting frame 1, a conveying assembly 2, sliders 4, a motor 5, telescopic rods 7, elastic elements 71, clamping blocks 8, wedge frames 9, a spraying chamber 11, spray nozzles 12, an isolation assembly, and a curing assembly. The conveying assembly 2 is installed inside the mounting frame 1. Multiple sets of sliders 4 are installed on the conveying assembly 2 in the conveying direction. A motor 5 is installed on any slider 4. The output shaft end of the motor 5 is provided with a circular seat, and at least three telescopic rods 7 are distributed in a circular array on the side wall of the circular seat. Each telescopic rod 7 is connected to an elastic element 71. The outer end of the telescopic rod 7 is connected to a clamping block 8, and each clamping block 8 is connected to a wedge frame 9. The top of the mounting frame 1 is also equipped with a spraying chamber 11, an isolation assembly, and a curing assembly. Multiple sets of spray nozzles 12 are provided inside the spraying chamber 11.

[0006] Compared with the prior art, the present invention has the following advantages: The present invention is provided with a telescopic rod, an elastic element and a clamping block. The internal clamping method can prevent the centrifuge shell from shifting during spraying and can also prevent any direct physical damage to the outer surface of the centrifuge shell. This allows the entire outer surface of the centrifuge shell to be uniformly sprayed, thereby improving the uniformity and consistency of the coating. Attached Figure Description

Detailed Implementation

[0013] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0014] A centrifuge casing spraying device, such as Figures 1-5As shown, the system includes a mounting frame 1, a conveying assembly 2, sliders 4, motors 5, telescopic rods 7, elastic elements 71, clamping blocks 8, wedge frames 9, a spray chamber 11, spray nozzles 12, an isolation assembly, and a curing assembly. The mounting frame 1 houses the conveying assembly 2, which has multiple sets of sliders 4 mounted on it in the conveying direction. Each slider 4 is equipped with a motor 5. The output shaft of the motor 5 has a circular seat at its end, and at least three telescopic rods 7 are arranged in a circular array on the sidewall of the circular seat. Each telescopic rod 7 is connected to an elastic element 71, and the outer end of each telescopic rod 7 is connected to a clamping block 8. Each clamping block 8 is connected to a wedge frame 9. The top of the mounting frame 1 also houses the spray chamber 11, the isolation assembly, and the curing assembly. The spray chamber 11 contains multiple sets of spray nozzles 12.

[0015] Silicone isolation strips 3 are also provided on the upper surface of the conveying component 2 and on both sides of the running track of the slider 4. The silicone isolation strips 3 can prevent paint from being sprayed onto the conveying component 2.

[0016] A silicone sleeve 6 is fitted around the outer periphery of the motor 5, and a silicone top 10 is provided above the motor 5. The silicone sleeve 6 is connected to the slider 4, and the output shaft of the motor 5 passes through the silicone sleeve 6. The outer periphery of the silicone top 10 is connected to the clamping block 8. The silicone top 10 can prevent paint from being sprayed onto the telescopic rod 7 and the clamping block 8, and the silicone sleeve 6 can prevent paint from being sprayed onto the motor 5, thus avoiding the paint from affecting the conveying assembly 2, the telescopic rod 7, the clamping block 8, and the motor 5.

[0017] This invention also includes an exhaust gas collector 13, which is connected to the top of both the spray booth 11 and the curing chamber 16. The exhaust gas collector 13 can effectively capture harmful gases generated during spraying, reducing the pollution of the working environment by harmful gases.

[0018] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the curing assembly includes a curing chamber 16 and a curing lamp 17. The curing chamber 16 is installed on top of the frame 1 and located behind the spray booth 11, and the curing lamp 17 is installed inside the curing chamber 16. Both the left and right sides of the spray booth 11 and the left and right sides of the curing chamber 16 are open. Here, the left side of the spray booth 11 is open, that is, the entrance is fixedly connected to a shielding curtain.

[0019] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the isolation assembly includes an electric guide rail 14 and an isolation plate 15; the electric guide rail 14 is vertically mounted above the curing chamber 16, and the isolation plate 15 is located between the spraying chamber 11 and the curing chamber 16. The isolation plate 15 is mounted on the electric guide rail 14 and moves up and down via the electric guide rail 14 to achieve both communication and isolation between the spraying chamber 11 and the curing chamber 16.

[0020] The usage of this utility model is as follows: In the initial state, the elastic element 71 is in normal condition. When spraying the centrifuge shell, the isolation plate 15 blocks the spraying chamber 11. First, the slider 4 is transported to the left side of the mounting frame 1 by the conveying component 2, so that the slider 4 is located outside the spraying chamber 11. Correspondingly, the centrifuge shell is aligned with the silicone top 10, and the centrifuge shell is moved downward to press the inclined surface of the wedge frame 9. The wedge frame 9 moves towards the output shaft of the motor 5, so that the wedge frame 9 drives the clamping block 8 to compress the telescopic rod 7. The elastic element 71 is compressed. Under the elastic force of the elastic element 71, the clamping block 8 continuously presses and fixes the inner wall of the centrifuge shell, thereby fixing the centrifuge shell. Then, the conveying component 2 drives the slider 4 to move the centrifuge shell into the spraying chamber 11, and the centrifuge shell is sprayed by the nozzle 12. After that, the motor 5 drives the centrifuge shell to rotate, which facilitates the complete spraying of the centrifuge shell. Internal clamping prevents displacement of the centrifuge casing during spraying and avoids any direct physical damage to its outer surface, ensuring uniform spraying across the entire casing and improving coating uniformity and consistency. After spraying, the electric guide rail 14 moves the isolation plate 15 upwards away from the mounting frame 1. The conveyor assembly 2 drives the slider 4 to move the centrifuge casing into the curing chamber 16. The curing lamp 17 irradiates and cures the coating on the centrifuge casing, forming a stronger chemical bond between the coating and the outer surface of the casing, significantly improving adhesion and ensuring the coating adheres firmly to the casing even in harsh environments, preventing peeling or detachment. After curing, the conveyor assembly 2 moves the slider 4 to the top right side of the mounting frame 1, and the centrifuge casing is then moved upwards and removed. The elastic element 71 returns to its original shape, completing the centrifuge casing spraying. Continuous spraying is achieved through the conveyor assembly 2.
