Description

Technical Field

[0001] The utility model relates to the technical field of cold pumps for coating machines, and specifically relates to a cold pump for a coating machine with an additional valve structure. Background Technique

[0002] Coating machines are mainly used for coating the surfaces of products. The thin film material needs to be first evaporated into atoms or molecules, and then move in a straight line with a relatively large mean free path, collide with the product surface and condense to form a thin film, so as to form a stable coating for use;

[0003] In the cold pump system of a coating machine, installing a valve is also an important link during use, which can effectively control the flow rate and pressure of the refrigerant, thereby improving the refrigeration effect and stability of the entire system;

[0004] During the use process, when the installed valve of the cold pump is assembled, it is not convenient to effectively control the stability of the valve assembly, and when it is damaged, it is not convenient to replace it quickly;

[0005] In order to overcome the above defects, the prior art (a Chinese patent with the application number CN202122444807.2 and the application date of October 12, 2021) a cold pump device for a vacuum coating machine, the cold pump needs to pre-pump itself to reduce the temperature of its cold plate. At this time, the valve flap is sealed with the valve seat. In this way, only the second chamber is pumped during the vacuum formation process of the cold pump, and the valve flap isolates the second chamber from the first chamber, that is, it isolates it from the coating chamber. At the same time, the vacuum pumping pipe interface on the first chamber can be conveniently connected to the vacuum pumping system, so that the coating chamber and the first chamber can be pumped simultaneously. In this way, the formation speed of the cold pump's own vacuum is accelerated, the waiting time for the preliminary preparation is shortened, and the coating rhythm of the vacuum coating machine is shortened; and because a maintenance port is also provided on the side wall of the cooling cavity, a maintenance door is hinged at the maintenance port, and a sealing structure and a quick locking structure are provided between the maintenance door and the edge of the maintenance port. This maintenance port can facilitate the internal maintenance and repair;

[0006] Although the prior art can complete the installation of the valve and form a stable assembly, when installing the valve on the cold pump, it is not convenient to control the stability of the assembly. Under the vibration during long-term operation, the connection is likely to become unstable, affecting the stability of the overall valve installation work.

[0007] In view of the above problems, there is an urgent need to innovate and design on the basis of the original cold pump of the coating machine. Content of the Utility Model

[0008] The purpose of the present utility model is to provide a cold pump for a coating machine with an additional valve structure, so as to solve the problem that when assembling and installing a valve on the cold pump, it is inconvenient to control the stability of the assembly, and under the vibration during long-term operation, the connection is prone to instability, affecting the stability of the overall valve installation work as described in the above background technology.

[0009] To achieve the above object, the present utility model provides the following technical solution: A cold pump for a coating machine with an additional valve structure, which is provided with a cold pump body for the operation of the coating machine, and a first connecting pipe is installed on the lower surface of the cold pump body;

A push rod is rotatably connected to the upper surface of the slider. At the same time, a pressing rod is rotatably connected to the left side of the outer surface of the push rod, and a positioning rod is rotatably connected to the lower side of the outer surface of the pressing rod, and the positioning rod is installed on the outer surface of the first connecting pipe;

A clamping ring is connected to the outer surface of the compression spring, and the clamping ring is clamped on the side of the outer surface of the pressing rod.

[0014] Preferably, the positioning columns are installed in an equiangular and embedded manner at the outer surface end of the first connecting pipe. The first connecting pipe and the sealing ring and the second connecting pipe form a penetrating positioning structure through the positioning columns, and the second connecting pipe and the valve body form an integrated structure.

[0015] Through the above structure, it is convenient to form a positioning butt joint between the first connecting pipe and the second connecting pipe during use, so as to form a stable butt joint assembly with the valve body, and control the stability during the use of the valve body and the cold pump body.

[0016] Preferably, the locking assembly and the first connecting pipe form an integrated structure, and the locking assembly and the locking ring form an internal nested structure. The first connecting pipe and the locking ring form a positioning rotation structure through the nested ring. The outer surface shape of the locking ring is a threaded structure, and the locking ring and the handle are installed in an embedded manner on the outer surface.

[0017] With the above structure, during use, the locking ring on the locking assembly can be effectively controlled, and the handle can be used to control the locking ring to form a positioning rotation.

[0018] Preferably, the slider is slidably arranged at equal angles on the inner surface of the locking assembly, and the slider and the locking ring form a threaded structure. At the same time, the slider and the push rod form a rotating structure, and the push rod and the extrusion rod form a rotating structure. Moreover, the extrusion rod and the connecting pipe 1 form a positioning rotation structure through the positioning rod. Meanwhile, the outer surface shape of the extrusion rod is a bent serrated structure.

[0019] With the above structure, during use, it is convenient to control the slider to form a limiting slide through the threaded structure of the locking ring, and then extrude and adjust the push rod. Under the positioning rotation control of the positioning rod, the extrusion rod forms a stable flip, and the stability of the extrusion rod during use on the connecting pipe 1 is controlled.

The limit block forms an elastic sliding structure with the limit assembly through the return spring. Meanwhile, the limit assembly and the connecting pipe 1 form an integral structure, and the limit block forms a nested telescopic structure with the limit assembly through the unlocking member.

[0022] With the above structure, during use, when the locking ring rotates, the ratchet gear can be effectively controlled to rotate synchronously.

[0023] Preferably, the positioning ring and the connecting pipe 2 form an integral structure, and the positioning ring and the clamping ring form an elastic sliding structure through the extrusion spring. The clamping ring and the outer side of the extrusion rod form a limit snap-fitting structure.

[0024] With the above structure, during use, it is convenient to effectively control the elastic adjustment of the clamping ring on the positioning ring. When the extrusion rod forms an extrusion on the connecting pipe 2, the clamping ring can form a secondary snap-fitting positioning on the extrusion rod to avoid slipping.

[0025] Compared with the prior art, the beneficial effects of the present utility model are:

[0026] 1. The cold pump of the coating machine with an additional valve structure is provided with connecting pipe 1 and connecting pipe 2 that facilitate positioning and assembly. They form a positioning and sealing fit with the positioning posts and sealing rings. When connecting pipe 1 and connecting pipe 2 are butted, the extrusion rod on the locking assembly can form a positioning and clamping on connecting pipe 2. With the use of the snap ring, the stability of the assembly of the extrusion rod is improved.

[0038] A slider 11 is slidably connected to the inner surface of the locking assembly 7, and the outer surface of the slider 11 is threadedly connected to the outer surface of the locking ring 8, and a push rod 12 is rotatably connected to the upper surface of the slider 11, and a pressing rod 13 is rotatably connected to the left side of the outer surface of the push rod 12, and a positioning rod 14 is rotatably connected to the lower side of the outer surface of the pressing rod 13, and the positioning rod 14 is installed on the outer surface of the first connecting pipe 2;

[0039] The positioning columns 3 are installed in an equiangular and embedded manner at the outer surface end of the first connecting pipe 2, and the first connecting pipe 2 and the sealing ring 4 and the second connecting pipe 5 form a penetrating positioning structure through the positioning columns 3, and the second connecting pipe 5 and the valve body 6 form an integral structure.

[0040] The locking assembly 7 and the first connecting pipe 2 form an integral structure, and the locking assembly 7 and the locking ring 8 form an internal nested structure, and the first connecting pipe 2 and the locking ring 8 form a positioning rotation structure through the nested ring 10, and the outer surface shape of the locking ring 8 is a threaded structure, and the outer surface of the locking ring 8 and the handle 9 are installed in an embedded manner.

[0041] The sliders 11 are slidably arranged at equal angles on the inner surface of the locking assembly 7, and the slider 11 and the locking ring 8 form a threaded structure, and the slider 11 and the push rod 12 form a rotation structure, and the push rod 12 and the pressing rod 13 form a rotation structure, and the pressing rod 13 and the first connecting pipe 2 form a positioning rotation structure through the positioning rod 14, and the outer surface shape of the pressing rod 13 is a bent serrated structure.

[0042] On the right side of the outer surface of the locking ring 8, a ratchet gear 15 is installed. The outer surface of the ratchet gear 15 is engaged with a limit block 18. An unlocking member 19 is installed on the upper surface of the limit block 18. At the same time, a return spring 17 is nested and connected to the upper side of the outer surface of the limit block 18. The limit block 18 and the return spring 17 are nested and connected with a limit assembly 16, and the limit assembly 16 is installed on the outer surface of the first connecting pipe 2;

[0043] The ratchet gear 15 and the locking ring 8 form an integrated structure. The ratchet gear 15 and the limit block 18 form a limit engagement structure. The limit block 18 and the limit assembly 16 form an elastic sliding structure through the return spring 17.

[0044] During use, the cold pump body 1 is stably assembled on the coating machine. At the other end of the outer surface of the cold pump body 1, the first connecting pipe 2 is assembled. The sealing ring 4 nested with the positioning column 3 installed in cooperation with the first connecting pipe 2 effectively forms a stable nested assembly with the second connecting pipe 5, thereby controlling the stability between the second connecting pipe 5 and the valve body 6. When the first connecting pipe 2 and the second connecting pipe 5 are assembled, the locking ring 8 assembled with the control handle 9 forms a limit rotation on the inner surface of the locking assembly 7 installed on the first connecting pipe 2.

Since the positioning rod 14 is stably assembled on the first connecting pipe 2, the stability of the positioning rotation of the extrusion rod 13 can be controlled. Therefore, due to the positioning rotation of the extrusion rod 13, the serrated structure at the end of the extrusion rod 13 can be controlled to contact the outer surface of the second connecting pipe 5, thereby controlling the docking stability of the second connecting pipe 5. When the locking ring 8 rotates, the ratchet gear 15 installed on the locking ring 8 can be synchronously controlled to rotate, and the ratchet gear 15 and the limit block 18 are controlled to form a limit engagement. Thus, the return spring 17 assembled with the limit assembly 16 elastically adjusts the limit block 18, and an automatic locking limit can be formed when the ratchet gear 15 rotates. And during later replacement and removal, the unlocking member 19 installed on the limit block 18 can be controlled to move upward, causing the limit block 18 to disengage from the ratchet gear 15, and then rotating the locking ring 8 reversely to control the extrusion rod 13 to disengage from the second connecting pipe 5 for replacement use;

[0045] A positioning ring 20 is installed on the outer surface of the second connecting pipe 5. The inner surface of the positioning ring 20 is nested and connected with a compression spring 21. The outer surface of the compression spring 21 is connected with a snap ring 22, and the snap ring 22 is engaged on the outer surface side of the extrusion rod 13.

[0046] The positioning ring 20 and the second connecting pipe 5 form an integrated structure, and the positioning ring 20 forms an elastic sliding structure with the pressing spring 21 and the snap ring 22, and the snap ring 22 forms a limit engagement structure with the outer side of the pressing rod 13.

[0047] When the pressing rod 13 forms a flipping engagement, the end of the pressing rod 13 presses the positioning ring 20 installed on the second connecting pipe 5 and the outer side of the snap ring 22 assembled with the positioning ring 20, so as to control the serrated structure on the outer side of the pressing rod 13 to form a limit engagement with the snap ring 22 elastically adjusted by the pressing spring 21, and cooperate with the limit assembly 16 to form a double-positioning engagement with the pressing rod 13, avoiding loosening of the pressing rod 13 during later use and improving the assembly stability of the first connecting pipe 2 and the second connecting pipe 5.
