Description

Technical Field

[0001] This utility model relates to the field of sealing ring production technology, and in particular to a sealing ring surface coating electrostatic spraying and drying production line. Background Technology

[0002] A sealing ring is a device used to prevent the leakage of liquids or gases. It is usually made of elastic materials and has a sealing function. The choice of materials is of great significance to its sealing performance and service life. The performance of the materials directly affects the performance of the sealing ring.

[0003] To improve the performance and service life of sealing rings, electrostatic spraying of epoxy, polyurethane, and acrylic coatings is now used. During electrostatic spraying, the spray gun is connected to the negative terminal of a high-voltage electrostatic generator, while the object being coated is grounded as the positive terminal. When the spray gun sprays out the coating, the coating particles become negatively charged. Under the influence of the electrostatic field, the coating particles fly along the direction of the electric field towards the positively charged surface of the sealing ring, and are evenly adsorbed on its surface, forming a uniform coating. At the same time, the automatic roller spraying machine tumbles the sealing ring, thereby turning the internal components of the equipment.

[0004] Automatic roller sprayers have an observation port for easy inspection of the spraying effect by removing the internal sealing ring using tools. However, the observation port is open, which makes it easy for foreign objects to enter and affect the spraying effect. In addition, the sprayed paint may leak out from the observation port and contaminate the working environment.

[0005] Therefore, it is necessary to provide an electrostatic spraying and drying production line for sealing ring surface coating to solve the above-mentioned technical problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First embodiment:

[0027] Please refer to the following: Figures 1-3 The present invention provides an electrostatic spraying and drying production line for a sealing ring surface coating, comprising: a spraying device 1, a sealing device 2, and a limiting component 3.

[0028] The sealing device 2 includes a sealing groove 21, a baffle 22, and a telescopic member 23. The sealing groove 21 is opened inside the spraying device 1, the baffle 22 is slidably connected to the inside of the sealing groove 21, and one end of the telescopic member 23 is fixedly installed on one side of the baffle 22. The telescopic member 23 is used to push the baffle 22 to move. The limiting component 3 includes two limiting grooves 31 and two limiting blocks 32. Both limiting grooves 31 are opened inside the spraying device 1, and the two limiting blocks 32 are slidably connected to the inside of the two limiting grooves 31 respectively.

[0029] The baffle 22 is made of glass and is used to facilitate the inspection of the spraying situation inside the spraying device 1. A sealing ring is fixedly connected to one side of the baffle 22 to increase the sealing effect of the baffle 22.

[0030] The two limit blocks 32 are used to limit the baffle 22 while increasing the stability of the baffle 22 when it moves.

[0031] The top and bottom of the two limiting blocks 32 are fixedly connected to the top and bottom of the baffle 22, respectively.

[0032] The telescopic component 23 is an electric push rod. One end of the electric push rod is fixedly installed on the surface of the spraying device 1, and the other end is fixedly installed on the surface of the baffle 22.

[0033] The telescopic component 23 is a cylinder or hydraulic rod, which is installed in the same way as the electric push rod, and is used to push the baffle 22 to move.

[0034] The working principle of this first embodiment is as follows:

[0035] In use, the observation port of the spraying device 1 is sealed by the baffle 22, thereby preventing foreign objects from entering the interior of the spraying device 1 while the spraying device 1 is spraying, and preventing paint leakage from polluting the working environment.

[0036] When it is necessary to open the baffle 22, the telescopic component 23 is activated to retract, causing the baffle 22 to move to one side inside the sealing groove 21. This causes the two limiting blocks 32 to move to one side inside the two limiting grooves 31 respectively. Once the baffle 22 has moved to the appropriate position, the telescopic component 23 can be closed.

[0037] When it is necessary to close the baffle 22, the baffle 22 can be moved to one side inside the sealing groove 21 by activating the telescopic component 23 to close it.

[0038] In this first embodiment, the observation port of the spraying device 1 is sealed by the baffle 22, thereby preventing foreign objects from entering the interior of the spraying device 1 when the spraying device 1 is performing spraying work, and preventing paint leakage from polluting the working environment. In addition, the telescopic component 23, together with the sealing groove 21 and the limiting component 3, automatically opens the baffle 22, thereby facilitating the staff to sample and inspect the materials inside the spraying device 1.

[0039] Second embodiment:

[0041] Specifically, the difference in the electrostatic spraying and drying production line for sealing ring surface coating provided in the second embodiment of this application is that, in the electrostatic spraying and drying production line for sealing ring surface coating, a filter device 4 is provided on one side of the spraying device 1. The filter device 4 includes a filter box 41, a fan 42, a filter element 43, multiple air outlets 44 and a conveying pipe 45. The filter box 41 is fixedly installed on the surface of the spraying device 1, the fan 42 is fixedly installed inside the filter box 41, the filter element 43 is disposed inside the filter box 41, the multiple air outlets 44 are all opened inside the filter box 41, and one end of the conveying pipe 45 is fixedly installed inside the filter box 41.

[0042] Multiple air vents 44 are opened inside the filter box 41 and are located at opposite ends of the delivery pipe 45.

[0043] Multiple air vents 44 are used to discharge the filtered gas inside the filter box 41.

[0044] One end of the delivery pipe 45 is located on one side of the fan 42, and the other end is fixedly installed inside the baffle 22.

[0045] The delivery pipe 45 is used to deliver the gas inside the spraying device 1 into the filter box 41, where it is filtered by the filter element 43.

[0046] The filter element 43 is a movable carbon layer used to filter the gas discharged from the delivery pipe 45.

[0047] The filter element 43 is fixedly installed inside the filter box 41 and is used to filter the gas discharged from the delivery pipe 45.

[0048] The working principle of this second embodiment is as follows:

[0049] When in use, after the fan 42 is turned on, the gas inside the spraying device 1 is drawn into the filter box 41 through the delivery pipe 45, filtered by the filter element 43, and then discharged through multiple air outlets 44.

[0050] In this second embodiment, the air inside the spraying device 1 is filtered by the filter device 4, thereby reducing the emission of toxic gases.
