Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PVD coating technology, and particularly relates to a PVD coating equipment spraying device facilitating uniform spraying. BACKGROUND

[0002] PVD refers to a process in which, under vacuum conditions, low-voltage and large-current arc discharge technology is used to ionize both the evaporated material and the gas by using gas discharge to evaporate the target material, and the accelerated action of the electric field is used to deposit the evaporated material and its reaction products on the workpiece. The function is to spray some microparticles with special properties on a matrix with lower performance, so that the matrix has better performance. In the installation process, the spraying device is difficult to install and takes a long time, and there are deficiencies, such as the particles in the coating easily precipitate during the spraying process, resulting in uneven mixing of the coating, thereby reducing the spraying effect. Some devices do not have a pre-filtering function, and if there are large particles or impurities in the unevenly mixed coating, the processing quality will be affected. Some devices do not have an auxiliary rotating function, and cannot rotate and spray the outer surface of the device, making it difficult to ensure the uniformity of the coating.

[0003] In view of the above and the existing related technology, the inventors believe that the following defects often exist: When the staff installs, it is difficult to operate and damage the internal parts. Generally, the device for installing the spraying pipe has complex parts, and the staff is easy to damage the parts during operation, and the operation time is long. SUMMARY

Therefore, we propose a PVD coating equipment spraying device facilitating uniform spraying.

[0005] In order to achieve the above purpose, the following technical scheme is adopted in the present application: a PVD coating equipment spraying device facilitating uniform spraying, comprising a spraying pipe, one end of the spraying pipe is provided with a spray head, one end of the spraying pipe is provided with a mounting and dismounting device, the mounting and dismounting device comprises a mounting pipe, the mounting pipe is fixedly connected with one end of the spraying pipe, the surface of the mounting pipe is slidably connected with an external pipe, two mounting grooves are formed in the surface of the mounting pipe, a first spring is fixedly connected to the inner surface of the mounting groove, the other end of the first spring is fixedly connected with a blocking block, two threaded rods are threadedly inserted into the circular arc surface of the external pipe, and two circular holes are formed in the inner surface of the mounting pipe.

By arranging the installation and dismounting device 3, the staff can easily install the pipe, avoiding damage to the internal parts during installation. The device for installing the spraying pipe 1 is usually complex, and the staff is easy to damage the parts during operation, and the operation time is longer. The new structure enables the staff to install the pipe in a simple way, improving the staff's working enthusiasm. The surface of the spray head 2 is provided with a protective device 4. By arranging the protective device 4, the staff can prevent pollution when not using the spray head 2, avoiding the situation that the pipe in the spray head 2 is polluted and blocked.

Over time, the internal pipe and other key components may be damaged due to pollution.

[0024] The specific arrangement and function of the installation and dismounting device 3 and the protective device 4 will be described in detail below.

[0025] ReferenceFigure 2 And Figure 3 As shown in FIG. 1, in the embodiment: the installation and dismounting device 3 comprises an installation pipe 301, the installation pipe 301 is fixedly connected with one end of the spraying pipe 1, the surface of the installation pipe 301 is slidably connected with an external connecting pipe 306, two installation grooves 302 are arranged on the surface of the installation pipe 301, the inner surface of the installation groove 302 is fixedly connected with a first spring 303, the other end of the first spring 303 is fixedly connected with a blocking block 304, two threaded rods 305 are threadedly inserted into the arc surface of the external connecting pipe 306, and two round holes 307 are arranged on the inner surface of the installation pipe 301. One end of the installation pipe 301 is slidably connected with a leak-proof pad 308, and the size of the leak-proof pad 308 is matched with the size of the installation pipe 301. In the pipeline system for conveying paint, the sealing between the installation pipe 301 and the external connecting pipe 306 is enhanced, and paint leakage is prevented. The inner surface of the round hole 307 is slidably connected with a round rod 309, the arc surfaces of the two round rods 309 are slidably connected with a movable frame 310, the arc surface of the round rod 309 is fixedly connected with a handle 311, and the ends of the two round rods 309 close to each other are fixedly connected with a second spring 312.

The arc surface of the threaded rod 305 is fixedly connected with a baffle 313, and one side of the baffle 313 abuts against the installation pipe 301. By arranging the baffle 313, when the side of the baffle 313 abuts against the arc surface of the external connecting pipe 306, the top end of the blocking block 304 is flush with one side of the arc surface of the installation pipe 301, which is more conducive to the dismounting of the external connecting pipe 306 by the staff.

[0026] Referring to Figure 4 And Figure 5 As shown in FIG. 1, in the embodiment: the installation and dismounting device 3 comprises an installation pipe 301, the installation pipe 301 is fixedly connected with one end of the spraying pipe 1, the surface of the installation pipe 301 is slidably connected with an external connecting pipe 306, two installation grooves 302 are arranged on the surface of the installation pipe 301, the inner surface of the installation groove 302 is fixedly connected with a first spring 303, the other end of the first spring 303 is fixedly connected with a blocking block 304, two threaded rods 305 are threadedly inserted into the arc surface of the external connecting pipe 306, and two round holes 307 are arranged on the inner surface of the installation pipe 301. One end of the installation pipe 301 is slidably connected with a leak-proof pad 308, and the size of the leak-proof pad 308 is matched with the size of the installation pipe 301.
