Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating machines, in particular to a vacuum pumping device for vacuum coating machines. Background Art

[0002] A vacuum coating machine is a device that coats a thin film on the surface of a material through physical or chemical methods in a vacuum environment. When using a vacuum coating machine, it is inseparable from the use of a vacuum pump. The most common vacuum pump is a vacuum pump. The vacuum pump can achieve the purpose of efficiently vacuuming the coating machine, thereby improving the accuracy and uniformity of the coating.

[0003] A Chinese patent discloses an energy-saving vacuum coating machine vacuum pumping device (authorization announcement number CN221094273U). This patented technology facilitates the discharge of gas from the inner cavity of the vacuum coating machine body by setting a shell, a connecting pipe and a vacuum pump. By setting a forward and reverse motor, a screw rod, a connecting block, a fixing plate, a bottom plate, a top plate, a spring, a vertical rod, a triangular plate and a sealing gasket, a good vacuum effect is achieved, preventing gas from entering the vacuum coating machine body during operation.

[0004] However, most existing coating machines use vacuum pumps for vacuum extraction. Prolonged gas extraction by vacuum pumps increases heat generation, resulting in poor heat dissipation and a reduced service life. For example, the aforementioned reference document uses a vacuum pump to extract air. In practice, when the vacuum pump is performing vacuum extraction on the coating machine, it generates high heat due to prolonged operation, shortening its service life. Therefore, those skilled in the art have provided a vacuum pumping device for a vacuum coating machine to address the issues raised in the aforementioned background art. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution for a vacuum device for a vacuum coating machine: it includes: a vacuum coating machine 1 and an air outlet pipe 11 arranged on the outside of the vacuum coating machine 1, a vacuum box 2 is installed on the outside of the vacuum coating machine 1 above the air outlet pipe 11, two sets of movable plates 42 are slidably installed on the upper surface of the vacuum box 2, and a connecting plate 41 is installed on the upper surface of the two sets of movable plates 42. A heat dissipation box 4 is provided on the upper surface of the connecting plate 41, and a filter screen 46 is also installed inside the heat dissipation box 4, and a mounting plate 47 is installed below the filter screen 46 inside the heat dissipation box 4, and a heat dissipation fan 471 is installed on the upper surface of the mounting plate 47, and the upper surface of the vacuum box 2 is mounted between the two movable plates 42. There is a vacuum pump 3, and a connecting pipe 21 is also provided on the lower surface of the vacuum box 2. A second cylinder 5 is installed on the lower surface of the vacuum box 2 on one side of the connecting pipe 21. The telescopic end of the second cylinder 5 is connected to a sealing plate 51 inside the vacuum box 2. A sealing gasket is provided on the upper surface of the sealing plate 51. This setting utilizes the vacuum pump 3 on the upper surface of the vacuum box 2 to extract the air inside the vacuum coating machine 1, and after the extraction, the second cylinder 5 will work to make the sealing plate 51 move upward to seal the through hole to avoid air leakage. At the same time, when the vacuum pump 3 is working, the heat dissipation fan 471 inside the heat dissipation box 4 can also be used to dissipate heat for the vacuum pump 3, thereby improving the service life of the vacuum pump 3.

[0024] like Figure 2 and Figure 3 As shown, a through hole is opened on the upper surface of the vacuum box 2, and the exhaust end of the vacuum pump 3 is embedded in the inside of the through hole. This arrangement uses the vacuum pump 3 to allow the air in the vacuum coating machine 1 to enter the interior of the vacuum box 2 through the outlet pipe 11 and the connecting pipe 21, thereby achieving the purpose of vacuuming.

[0025] like Figure 3 and Figure 4 As shown, the interior of the vacuum box 2 is provided with a sealing ring 52 sleeved on the outside of the second cylinder 5, and the sealing gasket is in contact with the inner upper surface of the vacuum box 2. This arrangement utilizes the sealing ring 52 to seal the connection between the second cylinder 5 and the vacuum box 2, and at the same time, the sealing gasket can improve the sealing to avoid air leakage that affects the operation of the vacuum coating machine 1.

[0026] like Figure 1 and Figure 2As shown, the external thread of the air outlet pipe 11 is connected to the connecting sleeve 12, and the outside of the connecting pipe 21 is also provided with an external thread. The inner side of the connecting sleeve 12 is provided with an internal thread that screws together with the external threads. This setting utilizes the connecting sleeve 12 to rotate on the external threads of the connecting pipe 21 and the air outlet pipe 11, thereby facilitating subsequent air extraction work.

[0027] like Figure 5 As shown, an air inlet hole 44 is provided on the upper surface of the heat dissipation box 4, and a heat dissipation pipe 45 is symmetrically provided on the lower surface of the heat dissipation box 4. The lower surface of the heat dissipation pipe 45 passes through the lower surface of the connecting plate 41. This arrangement utilizes the air inlet hole 44 to draw external air into the interior of the heat dissipation box 4, and the drawn air can be discharged to the outside of the vacuum pump 3 through the heat dissipation pipe 45 to dissipate heat for the vacuum pump 3.

[0028] like Figure 2 and Figure 3 As shown, a guide block 421 is installed on the lower surface of the movable plate 42, and a movable groove 22 that slides with the guide block 421 is provided on the upper surface of the vacuum box 2. A first cylinder 43 is symmetrically arranged on the outer side of the vacuum box 2, and the telescopic end of the first cylinder 43 is connected to the middle position of one side of the guide block 421. This setting utilizes the operation of the first cylinder 43 to make the guide block 421 move inside the movable groove 22, and then the position of the heat dissipation box 4 can be adjusted to dissipate heat for the vacuum pump 3.

[0029] The working principle of the present invention is as follows: when the vacuum device of the present invention is used for a vacuum coating machine, the outlet pipe 11 is first connected to the connecting pipe 21 by rotating the connecting sleeve 12 on the external thread of the connecting pipe 21. After the connection, the inside of the vacuum coating machine 1 can be vacuumed by starting the vacuum pump 3. When vacuuming, the first cylinder 43 symmetrically arranged on one side of the vacuum box 2 is started, so that the guide block 421 moves inside the movable groove 22. At the same time, when moving, the heat dissipation fan 471 inside the heat dissipation box 4 is started, so that the external air enters the heat dissipation box 4 through the air inlet 44, and is filtered through the filter 46 after entering. At the same time, the filtered air is discharged to the outside through the heat dissipation pipe 45 to dissipate heat for the vacuum pump 3, thereby improving its service life. After vacuuming, when the second cylinder 5 is started, the sealing plate 51 is moved inside the vacuum box 2, and the through hole can be blocked and sealed by the sealing gasket, thereby avoiding air leakage and affecting the use of the vacuum coating machine 1.

[0030] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
