Description

Technical Field

[0001] The utility model relates to the field of gas mixing, in particular to a gas mixing device for spraying glass bottles. Background Art

[0002] When glass bottles are produced, some gas needs to be sprayed on the outer wall of the glass bottles. The sprayed gas can form a protective coating on the surface of the glass bottles, providing additional protection against scratches, breakage or chemical corrosion, thereby increasing the durability and service life of the glass bottles.

[0003] When applying for this utility model, the applicant found through search that a Chinese patent disclosed "a gas mixing device" with the application number "CN202021858694.X". This patent mainly achieves the effect of buffering and deflecting the gas, reducing the gas flow rate, and prolonging the residence time of the gas in the mixing device by setting an air inlet chamber, a mixing chamber and a filtering air outlet chamber, thereby ensuring the mixing effect; secondly, the stirring device can achieve the effect of uniform mixing of the gas and ensure the mixing quality.

[0004] However, when in use, gas is only injected into the interior of the device body through the air inlet pipe. After the gas is injected, the internal pressure of the device body will increase. When the gas is added, a part of the mixed gas will flow back into the gas injection pipe due to the pressure difference, causing the gas inside the pipe to be contaminated, affecting the next use. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a gas mixing device for spraying glass bottles.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a gas mixing device for spraying glass bottles, comprising a tank body, a top cover is arranged on the top of the tank body, an air inlet is fixedly connected to the top of the top cover, and the number of the air inlets is two, a sealing plate groove is opened at the bottom of the top cover, and the number of the sealing plate grooves is two, the inner walls of the two sealing plate grooves are opened with spring grooves, and the number of the spring grooves is two respectively, the tops of the inner walls of the two sealing plate grooves are fixedly connected with fixed blocks, the inner walls of the spring grooves are fixedly connected with springs, the other ends of the springs are fixedly connected with moving blocks, the other ends of the moving blocks are fixedly connected with moving plates, the outer walls of the other ends of the moving plates are fixedly connected with linkage columns, the insides of the two sealing plate grooves are installed with sealing plates, the tops of the sealing plates are fixedly connected with linkage plates, and the number of linkage plates is multiple, the inner walls of the multiple linkage plates are opened with linkage grooves, and the other ends of the linkage columns extend to the inside of the linkage grooves.

[0007] As a further description of the above technical solution:

[0008] The tops of the two sealing plates and the bottoms of the two fixing blocks are both provided with first sealing grooves, and first sealing rings are installed inside the first sealing grooves.

[0009] As a further description of the above technical solution:

[0010] The bottom of the tank body is fixedly connected with a motor, the output end of the motor is fixedly connected with a rotating shaft, the top of the rotating shaft extends to the inside of the tank body, the outer wall of the rotating shaft is fixedly connected with a stirring blade, and the number of the stirring blades is multiple.

[0011] As a further description of the above technical solution:

[0012] The top of the tank body and the bottom of the top cover are both provided with a second sealing groove, and a second sealing ring is installed inside the second sealing groove.

[0013] As a further description of the above technical solution:

[0014] The upper end of the outer wall of the tank body and the outer wall of the top cover are fixedly connected with fixing feet, and there are multiple fixing feet, which correspond to each other one by one and are connected by bolts.

[0017] The utility model has the following beneficial effects:

[0018] 1. The gas enters the tank through two air inlets respectively. Due to the pressure of the gas entering, the sealing plate will be pushed out of the sealing plate groove. When the sealing plate top moves down, the linkage column will move along the linkage groove opened inside the linkage plate connected to the top of the sealing plate, thereby driving the moving plate and the moving block to move toward the spring groove. The moving block moves along the spring groove. At this time, the spring is in a compressed state. After the sealing plate is completely moved out of the sealing plate groove, there is a gap between the sealing plate and the sealing plate groove. The gas can enter the tank through the gap. As the pressure inside the tank increases and with the rebound effect of the spring, the sealing plate returns to its original position at a very fast speed, pushing the gas in. The air port is sealed to prevent the mixed gas from entering the air inlet and causing the gas in the air inlet to be contaminated. The existing device only injects gas into the interior of the device body through the air inlet pipe when in use. After the gas is injected, the internal pressure of the device body will increase. When the gas is added, a part of the mixed gas will flow back to the inside of the gas injection pipe due to the pressure difference, causing the gas inside the pipe to be contaminated, affecting the next use. The device can prevent the mixed gas from flowing back and causing the gas inside the air inlet to be contaminated, thereby affecting the next gas addition, thereby achieving the effect of preventing the gas from being contaminated.

[0019] 2. By setting up a motor, the motor drives the shaft to rotate, and multiple stirring blades connected to the outer wall of the shaft rotate accordingly, stirring and mixing the gas inside the tank body, increasing the mixing speed, and then the solenoid valve opens, and the mixed gas in the tank body is discharged through the outlet.

[0031] The gas enters the tank body 1 through the two air inlets 3 respectively. Due to the pressure when the gas enters, the sealing plate 11 will be pushed out of the sealing plate groove 4. When the sealing plate 11 moves down, the linkage column 10 will move along the linkage groove 13 opened inside the linkage plate 12 connected to the top of the sealing plate 11, thereby driving the moving plate 9 and the moving block 8 to move toward the spring groove 5. The moving block 8 moves along the spring groove 5. At this time, the spring 7 is in a compressed state. After the sealing plate 11 is completely moved out of the sealing plate groove 4, there is a gap between the sealing plate 11 and the sealing plate groove 4. The gas can enter the tank body 1 through the gap. As the internal pressure of the tank body 1 increases, and with the rebound effect of the spring 7, the sealing plate 11 returns to its position rapidly to seal the air inlet 3.

[0032] A motor 16 is fixedly connected to the bottom of the tank body 1, and a rotating shaft 17 is fixedly connected to the output end of the motor 16. The top of the rotating shaft 17 extends to the interior of the tank body 1. A stirring blade 18 is fixedly connected to the outer wall of the rotating shaft 17, and there are multiple stirring blades 18. The operation of the motor 16 drives the rotating shaft 17 to rotate, and the multiple stirring blades 18 connected to the outer wall of the rotating shaft 17 rotate accordingly, thereby stirring and mixing the gas inside the tank body 1.

[0033] A first sealing groove 14 is formed at the top of the two sealing plates 11 and the bottom of the two fixing blocks 6 , and a first sealing ring 15 is installed inside the first sealing groove 14 .

The lower end of the outer wall of the tank body 1 is fixedly connected with an air outlet 22, and the top of the air outlet 22 is fixedly connected with a solenoid valve 23. When the solenoid valve 23 is opened, the mixed gas in the tank body 1 is discharged through the air outlet 22. The bottom of the tank body 1 is fixedly connected with supporting feet 24, and there are multiple supporting feet 24.

[0035] Working principle: Gas enters the tank body 1 through the two air inlets 3 respectively. Due to the pressure when the gas enters, the sealing plate 11 will be pushed out of the sealing plate groove 4. When the sealing plate 11 moves down, the linkage column 10 will move along the linkage groove 13 opened inside the linkage plate 12 connected to the top of the sealing plate 11, thereby driving the moving plate 9 and the moving block 8 to move in the direction of the spring groove 5. The moving block 8 moves along the spring groove 5. At this time, the spring 7 is in a compressed state. After the sealing plate 11 is completely moved out of the sealing plate groove 4, there is a gap between the sealing plate 11 and the sealing plate groove 4. Gas can enter the tank body 1 through the gap. As the internal pressure of the tank body 1 increases, and with the rebound effect of the spring 7, the sealing plate 11 returns to its position rapidly and seals the air inlet 3. Then the motor 16 runs to drive the rotating shaft 17 to rotate, and the multiple stirring blades 18 connected to the outer wall of the rotating shaft 17 rotate accordingly to stir and mix the gas inside the tank body 1. Then the solenoid valve 23 is opened, and the mixed gas in the tank body 1 is discharged through the air outlet 22.
