Description

Technical Field

[0001] This utility model relates to the field of cold pump technology for coating machines, specifically a cold pump valve body docking mechanism that can be sealed and monitored. Background Technology

[0002] The main function of the cold pump used in the coating machine is to condense and adsorb the water vapor inside to avoid affecting the coating process. It is also used in conjunction with the valve body of the connected pipeline to facilitate the delivery of the cold pump cooling material. However, during use, it is inconvenient to control the cold pump valve body to ensure stable assembly, which affects the stability of pipeline delivery. Furthermore, it is easy to reduce the cooling effect in the event of a leak.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN202122444807.2, application date 2021-10-12) provides a cold pump device for a vacuum coating machine. In this device, the cold pump needs to be pre-evacuated to lower the temperature of its cold plate. At this time, the valve disc and valve seat are sealed. Thus, during the vacuum formation process, the cold pump only evacuates the second chamber. The valve disc isolates the second chamber from the first chamber, and consequently, from the coating chamber. Simultaneously, the vacuum pipe interface on the first chamber can be easily connected to the vacuum system, allowing for simultaneous evacuation of both the coating chamber and the first chamber. This accelerates the vacuum formation speed of the cold pump, shortens the pre-preparation waiting time, and reduces the coating cycle time of the vacuum coating machine. While the prior art can complete pipe connection, it is inconvenient to control the sealing of the connection during operation, and leaks are difficult to detect in a timely manner, affecting the assembly effect.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing sealable monitoring mechanism for cold pump valve bodies. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a sealable monitoring cold pump valve body docking mechanism, wherein a cold pump body 1 and a connecting pipe 2 for assembling the cold pump body 1 are provided;

[0026] Example 1: As Figure 1 and Figure 3 The present invention provides the following technical solution: a sealing and monitoring cold pump valve body docking mechanism, comprising: a second connecting pipe 3 docking with the side of a first connecting pipe 2, and a valve body 4 installed at the other end of the outer surface of the second connecting pipe 3, and a flange 5 installed on the outer surface of the first connecting pipe 2, and a sealing ring 6 attached to the outer surface of the flange 5, and a second flange 7 attached to the other end of the outer surface of the sealing ring 6, and the flange 7 is installed on the second connecting pipe 3, and the flange 5 is connected to the flange 7 through a rotary extrusion mechanism, and a rotating ring 13 is nested and rotatably connected to the outer surface of the flange 5, and the rotating ring 13 controls the sealing performance of the docking between the flange 5 and the flange 7 through the extrusion sealing mechanism.

[0027] In use, the connecting pipe 2 assembled with the cold pump body 1 and the flange 5 installed on the connecting pipe 2 are connected to the flange 7 with the sealing ring 6, thereby assembling the connecting pipe 3. The valve body 4 is then installed through the connecting pipe 3, which improves the stability of the docking assembly between the valve body 4 and the cold pump, as well as the sealing performance of the connection. The use of the clamp 11 assembled on the flange 5 improves the convenience of docking assembly and prevents detachment. Furthermore, the sealing air bladder 18 inside the flange 5 and the flange 7 can control the sealing effect during the adjustment of the locking mechanism and control the inflation of the sealing air bladder 18, thereby improving the sealing performance between the flange 5 and the flange 7. After the docking locking mechanism is assembled, the compression of the limiting member 24 will prevent the locking mechanism from disengaging.

[0028] Example 2: Figures 1-4 The technical solution shown, based on Embodiment 1, further discloses the convenience of snap-fit ​​connection and can simultaneously control multiple sets of snap-fit ​​parts 11 to operate synchronously, avoiding loose snap-fit ​​and solving the problem of cumbersome assembly. Its specific content is as follows: The rotary extrusion mechanism also includes a gear 8 rotatably connected to the outer surface of flange 5, and a threaded rod 9 is installed at the end of the outer surface of gear 8, which is nested and rotated on the inner surface of flange 5. An extrusion block 10 is threadedly connected to the outer surface of threaded rod 9, and the extrusion block 10 is limited and slidably positioned on the inner surface of flange 5. Please refer to... Figure 3 Flange 5 forms a rotating structure via gear 8 and threaded rod 9, and threaded rod 9 forms a threaded limiting sliding structure with pressing block 10. Gear 8 is set at an equal angle relative to the outer surface of flange 5. (See also...) Figure 4 A clamping element 11 is mounted on the outer surface of the compression block 10, and the clamping element 11 is locked and engaged with the outer end of the flange 7. A gear ring 12 is meshed with the outer surface of the gear 8, and a rotating ring 13 is mounted on the outer surface of the gear ring 12. A slider 14 is mounted on the outer surface of the rotating ring 13, and the slider 14 is locked and slids against the inner surface of the flange 5. A compression spring 15 is elastically connected between the slider 14 and the flange 5. (See also...) Figure 4 The extrusion block 10 and the clamp 11 form a nested oblique extrusion structure, and the flange 15 forms a limiting engagement structure with the flange 2 7 through the clamp 11. The gear 8 forms a meshing structure with the rotating ring 13 through the gear ring 12. At the same time, the rotating ring 13 forms an elastic limiting sliding structure with the flange 15 through the slider 14 and the extrusion spring 15.

[0029] In use, a connecting pipe 12 is assembled on the lower surface of the cold pump body 1, and a flange 5 is installed on the connecting pipe 12. A sealing ring 6 is assembled using a nested pin and connected to the flange 7 installed on the connecting pipe 23 assembled on the valve body body 4. This is used for the initial sealing treatment of the outer side of the connection between flange 15 and flange 27. The clamp 11 assembled on flange 15 will simultaneously pass through the engagement hole opened on flange 27. After docking and positioning, the rotating ring 13 on the control flange 15 will rotate, thereby driving the gear 8 installed on the inner diameter of the rotating ring 13 to mesh and rotate, and driving the threaded rod 9 assembled on the installed gear 8 to rotate and position on the inner surface of flange 15, thereby screwing... The extrusion block 10 assembled with the threaded rod 9 moves toward the mating surface of flange 5, and the extrusion block 10 unfolds by obliquely nesting the sliding extrusion clamp 11, thereby engaging the clamp 11 on the left side of flange 7, limiting the engagement between flange 7 and flange 5, improving the stability of engagement positioning. When using the rotating ring 13, the slider 14 installed on the rotating ring 13 needs to be rotated first to compress and shrink the clamping spring 15, and then flange 5 and flange 7 are mated. With the elastic reset of the clamping spring 15, the unfolding of the clamp 11 is controlled and used in conjunction with manual operation to improve engagement stability and avoid vibration unlocking in the later stage, thus improving the engagement effect.

[0030] Example 3: Figure 5 and Figure 6 The technical solution shown, based on Embodiment 2, further discloses the effects of compression sealing and nested engagement, improving the stability of sealing and engagement. During the sealing process, liquid monitoring can be used to detect whether leakage occurs during operation, improving the effectiveness of sealing monitoring and solving the problem of easy loosening and leakage that is difficult to detect. The specific details are as follows: The compression sealing mechanism also includes a compression airbag 16 nested inside the rotating ring 13, and the compression airbag 16 is positioned and assembled on the outer surface of the connecting pipe 2. An air pipe 17 is installed on the outer surface of the compression airbag 16, and a sealing airbag 18 is installed at the other end of the air pipe 17. The sealing airbag 18 is nested between flange 5 and flange 7, and a detection piece 19 is attached to the side of the sealing airbag 18. The rotating ring 13, connecting pipe 2, and compression airbag 16 form a compression structure, and the compression airbag 16, through the air pipe 17, forms a gas delivery structure with the sealing airbag 18. The sealing airbag 18, flange 5, and flange 7 form an embedded structure, and the sealing airbag 18 and detection piece 19 form a fitted structure. Figure 5 and Figure 6As shown, a positioning plate 20 is installed on the outer surface of the connecting pipe 2 3, and a telescopic component 21 is installed on the outer surface of the positioning plate 20. A limiting component 22 is assembled on the outer surface of the telescopic component 21. A return spring 23 is nested on the outer surface of the telescopic component 21, and a limiting element 24 is installed on the outer surface of the limiting component 22, which is engaged with the locking element 11. The connecting pipe 2 3 forms a telescopic structure with the positioning plate 20, the telescopic component 21, and the limiting component 22. The limiting component 22 forms an elastic structure with the positioning plate 20 through the return spring 23, and the limiting component 22 forms a limiting engagement structure with the locking element 11 through the limiting element 24.

[0031] When the rotating ring 13 is elastically reset and manually rotated, the compression airbag 16 between the rotating ring 13 and the connecting pipe 1 2 is squeezed synchronously. The gas is delivered to the sealing airbag 18 through the assembled air pipe 17, thereby improving the sealing effect between flange 1 5 and flange 2 7. The detection piece 19 is attached to the side of the sealing airbag 18 to monitor the sealing condition. After the assembly and locking are completed, the limiting member 24 squeezed during the assembly of the locking piece 11 will be controlled by the elastic force of the reset spring 23 built into the limiting component 22 installed on the outside of the limiting member 24 to automatically nest and lock the unfolded locking piece 11, improving the stability of the assembly of the locking piece 11. When the limiting component 22 is elastically controlled, the telescopic component 21 between the limiting component 22 and the positioning plate 20 is coordinated to improve the stability of the elastic telescopic adjustment and avoid the inaccuracy of the positioning between the limiting member 24 and the locking piece 11.
