Description

Technical Field

[0001] The utility model relates to the technical field of glue degassing, in particular to a glue degassing device. Background Art

[0002] In the prior art, vacuum degassing and stirring centrifugal degassing are usually adopted for glue. When vacuum degassing is adopted, the container filled with glue is evacuated to make the bubbles in the glue rise to the liquid surface under the action of pressure difference, and then break and release gas. When stirring centrifugal degassing is adopted, the glue is stirred in a vacuum environment, so that the bubbles in the glue rise to the liquid surface by using centrifugal force, and then break and release gas. For the above glue degassing methods, due to the high viscosity of the glue, the bubbles in the glue rise to the liquid surface very slowly, resulting in a long degassing time and reducing the degassing quality of the glue.

They are only for the convenience of description and simplifying operations, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] Existing glue degassing devices usually degas glue in the form of vacuum degassing and stirring centrifugal degassing. However, due to the high viscosity of the glue, the bubbles in the glue rise to the liquid surface very slowly, resulting in a long degassing time and also reducing the degassing quality of the glue.

[0043] To solve the above problems, as Figure 1 shown, this embodiment provides a glue degassing device. The glue degassing device includes a vacuum glue storage barrel 1, a degassing umbrella assembly 2, and a glue pumping assembly 3. Among them, the vacuum glue storage barrel 1 is used to provide a vacuum environment for storing glue. The degassing umbrella assembly 2 is located inside the vacuum glue storage barrel 1 and above the liquid level in the vacuum glue storage barrel 1. A glue flow port 231 is opened at the bottom of the degassing umbrella assembly 2. Part of the glue pumping assembly 3 is arranged outside the vacuum glue storage barrel 1. The glue inlet of the glue pumping assembly 3 is communicated with the bottom of the vacuum glue storage barrel 1, and the glue outlet of the glue pumping assembly 3 is communicated with the glue inlet of the degassing umbrella assembly 2. The glue pumping assembly 3 is used to extract the glue in the vacuum glue storage barrel 1 and send it back to the degassing umbrella assembly 2.

[0044] The glue degassing device provided in this embodiment provides a vacuum environment for storing glue by setting the vacuum glue storage barrel 1, so that the bubbles in the glue rise to the liquid surface under the action of the pressure difference and then break and release gas, thereby realizing the vacuum degassing of the glue.

[0045] At the same time, the glue degassing device, by setting the degassing umbrella assembly 2 and the glue pumping assembly 3, enables the glue pumping assembly 3 to extract the glue in the vacuum glue storage barrel 1 and send it back to the degassing umbrella assembly 2 in the vacuum glue storage barrel 1. The glue entering the degassing umbrella assembly 2 spreads out on the degassing umbrella assembly 2 to form a thin film, thereby exposing the bubbles in the glue, making the bubbles break and release gas in the vacuum environment. The glue degassed on the degassing umbrella assembly 2 flows back into the glue stored in the vacuum glue storage barrel 1 through the glue flow port 231 at the bottom of the degassing umbrella assembly 2, and thus circulates reciprocally, facilitating the exposure of the bubbles in the glue, enabling the glue degassing device to realize vacuum degassing and vacuum thin-film degassing, and effectively improving the degassing efficiency and degassing quality of the glue.

[0046] In addition, the glue in the vacuum glue storage barrel 1 is extracted by the glue extraction assembly 3 and sent back to the defoaming umbrella assembly 2, improving the extraction and reflux effect of the glue, and enabling the glue in the vacuum glue storage barrel 1 to be sent back to the defoaming umbrella assembly 2 more fully and thoroughly, further ensuring the defoaming quality and efficiency of the glue.

[0047] In this embodiment, the vacuum glue storage barrel 1 includes a barrel body 11 and a barrel cover 12. Among them, the barrel body 11 is used to store glue, and the barrel cover 12 is detachably buckled on the barrel body 11. When it is necessary to inject glue into the vacuum glue storage barrel 1, the barrel cover 12 can be detached from the barrel body 11. After the glue injection operation is completed, the barrel cover 12 is buckled on the barrel body 11 to ensure the airtight effect of the vacuum glue storage barrel 1. Optionally, a communication valve 122 is connected to the barrel cover 12, and the vacuum generator is connected to the communication valve 122. When it is necessary for the vacuum generator to extract vacuum from the vacuum glue storage barrel 1, the communication valve 122 can be opened. After the vacuum extraction operation is completed, the communication valve 122 can be closed to ensure that the vacuum glue storage barrel 1 provides a constant vacuum environment for the glue during the defoaming process of the glue. It should be noted that an air pressure detection component can be arranged in the vacuum glue storage barrel 1 to detect the air pressure value in the vacuum glue storage barrel 1 in real time. When the detection value of the air pressure detection component is higher than the preset air pressure value, the vacuum generator extracts vacuum from the vacuum glue storage barrel 1 through the communication valve 122 to ensure that the vacuum glue storage barrel 1 provides a constant vacuum environment for the glue and ensures the bubble breaking and gas release. Optionally, in this embodiment, the true air pressure in the vacuum glue storage barrel 1 can be stabilized at about 0.3 mbar.

[0048] In this embodiment, the glue extraction assembly 3 includes a glue outlet pipeline 31, a glue extraction pump 32, and a reflux pipeline 33 that are connected in sequence. The glue outlet pipeline 31 and the glue extraction pump 32 are both located outside the vacuum glue storage barrel 1. The glue inlet of the glue outlet pipeline 31 is connected to the bottom of the vacuum glue storage barrel 1, and the glue outlet of the reflux pipeline 33 is connected to the glue inlet of the defoaming umbrella assembly 2. When the glue extraction pump 32 is started, the glue in the vacuum glue storage barrel 1 can flow back to the defoaming umbrella assembly 2 through the glue outlet pipeline 31, the glue extraction pump 32, and the reflux pipeline 33 in sequence. By setting the glue extraction pump 32 to extract the glue in the vacuum glue storage barrel 1, the thickness of the film formed by the glue spread out on the defoaming umbrella assembly 2 can be adjusted by adjusting the power of the glue extraction pump 32, making the defoaming faster and improving the defoaming efficiency. In addition, by connecting the glue inlet of the glue outlet pipeline 31 to the bottom of the vacuum glue storage barrel 1, even in a vacuum environment, it can be ensured that the glue in the vacuum glue storage barrel 1 is extracted more fully and thoroughly, avoiding the deposition of the glue at the bottom of the vacuum glue storage barrel 1 and being difficult to extract. Optionally, in this embodiment, the glue extraction pump 32 can be a screw pump or a gear pump, and the specific form of the glue extraction pump 32 is not limited in this embodiment.

[0049] Optionally, in this embodiment, the glue outlet pipeline 31 is a corrugated hose. By designing the glue outlet pipeline 31 in the form of a corrugated hose, it is convenient to adjust the extension length and bending angle of the glue outlet pipeline 31, and better realize the connection between the glue outlet pipeline 31 and the glue pumping pump 32.

[0050] Optionally, in this embodiment, a discharge port 111 is provided at the bottom of the barrel body 11, and a switching valve 112 is provided at the discharge port 111. The glue inlet of the glue outlet pipeline 31 is communicated with the discharge port 111 through the switching valve 112. With the above setting, when the glue pumping pump 32 needs to be repaired, the switching valve 112 can be closed to prevent the glue in the barrel body 11 from flowing out through the discharge port 111 under the action of gravity. Optionally, the switching valve 112 can be a ball valve.

[0051] In this embodiment, as Figure 1 shown, the return pipeline 33 includes a return main pipeline 331 and multiple return branch pipelines 332. Among them, the return main pipeline 331 is located outside the vacuum glue storage barrel 1, the inlet of the return main pipeline 331 is communicated with the glue pumping pump 32, multiple return branch pipelines 332 are located inside the vacuum glue storage barrel 1, the inlet of each return branch pipeline 332 is communicated with the outlet of the return main pipeline 331, the glue outlet of each return branch pipeline 332 is communicated with the defoaming umbrella assembly 2, and the glue outlets of the multiple return branch pipelines 332 are arranged at intervals along the circumferential direction of the defoaming umbrella assembly 2. With the above setting, the multiple return branch pipelines 332 are connected in parallel, and the glue discharged from the return pipeline 33 flows into the defoaming umbrella assembly 2 from all around the defoaming umbrella assembly 2, ensuring that the glue flowing into the defoaming umbrella assembly 2 can be spread more evenly on the defoaming umbrella assembly 2, improving the defoaming effect.

[0052] Optionally, in this embodiment, the return pipeline 33 includes two return branch pipelines 332, which effectively ensures the uniformity of the glue spread on the defoaming umbrella assembly 2 from the defoaming umbrella assembly 2 on the basis of ensuring the cost. In other embodiments, three return branch pipelines 332 or even more return branch pipelines 332 can also be provided. Optionally, in this embodiment, the return pipeline 33 further includes a connector 333, the connector 333 is installed in the barrel cover 12, and the inlets of the multiple return branch pipelines 332 are all communicated with the outlet of the return main pipeline 331 through the connector 333. Optionally, in this embodiment, the connector 333 is a tee joint.

[0053] In this embodiment, the degassing umbrella assembly 2 includes a glue inlet pipeline 21, a first degassing umbrella 22 and a second degassing umbrella 23, wherein the glue outlet of each reflux branch pipeline 332 is connected to the glue inlet of the glue inlet pipeline 21, and a plurality of guide holes 211 are spaced apart on the outer peripheral wall of the glue inlet pipeline 21. The glue inlet pipeline 21 is arranged on the top of the first degassing umbrella 22, and the umbrella mouth of the first degassing umbrella 22 faces downward. The second degassing umbrella 23 is located below the first degassing umbrella 22, and the umbrella mouth of the second degassing umbrella 23 faces upward. A glue flow outlet 231 is provided at the bottom of the second degassing umbrella 23, and the umbrella mouth diameter of the second degassing umbrella 23 is larger than the umbrella mouth diameter of the first degassing umbrella 22. The above arrangement enables the glue entering the glue inlet pipeline 21 to flow into the outer umbrella surface of the first degassing umbrella 22 through each guide hole 211 and spread out on the outer umbrella surface of the first degassing umbrella 22 to form a thin film, thereby exposing the bubbles in the glue, so that the bubbles are broken and deflated under a vacuum environment, and the glue dripping on the outer umbrella surface of the first degassing umbrella 22 enters the inner umbrella surface of the second degassing umbrella 23 below, and the glue is spread out again on the inner umbrella surface of the second degassing umbrella 23 to form a thin film, and further degassing is performed. Finally, the glue on the inner umbrella surface of the second degassing umbrella 23 is collected at the bottom of the second degassing umbrella 23 and flows back to the glue stored in the vacuum glue storage barrel 1 through the glue flow port 231 at the bottom. The above arrangement enables the glue to be vacuum-film degassed twice, effectively prolonging the time when the bubbles are exposed to the vacuum, and effectively improving the degassing quality and degassing efficiency. In addition, since the diameter of the second degassing umbrella 23 is larger than that of the first degassing umbrella 22, it is ensured that all the glue dripping from the outer umbrella surface of the first degassing umbrella 22 is received by the inner umbrella surface of the second degassing umbrella 23. Optionally, in this embodiment, the bottom of the second degassing umbrella 23 is provided with a plurality of glue flow openings 231 spaced apart along its circumference, thereby avoiding glue residue in the second degassing umbrella 23.

The above arrangement, by stirring the glue in the vacuum glue storage barrel 1 through the stirring component 5, not only facilitates the glue to be mixed evenly, but also enables the bubbles in the glue to rise to the liquid surface under the action of centrifugal force, and then break and release the gas, thereby further improving the degassing efficiency and degassing quality.

[0056] In this embodiment, a through hole 121 is formed in the bucket cover 12. The stirring assembly 5 includes a stirring shaft 51 and stirring blades 52 arranged on the stirring shaft 51.

Optionally, in this embodiment, the stirring blades 52 can be paddle type, turbine type or anchor type, and the stirring blades 52 can also be in a U-shaped or double-wing structure. The specific form of the stirring blades 52 is not limited in this embodiment.

The magnetic fluid seal 13 is fixedly installed on the bucket cover 12 and is arranged above the through hole 121. The stirring shaft 51 rotates through the magnetic fluid seal 13. By providing the magnetic fluid seal 13, on the premise of ensuring the normal rotation of the stirring shaft 51, the sealing effect on the through hole 121 is effectively improved, and thus the airtightness of the entire vacuum glue storage bucket 1 is ensured. Since the specific structure and sealing principle of the magnetic fluid seal 13 belong to the prior art, they will not be elaborated here.

[0058] In this embodiment, the glue degassing device further includes a guiding assembly. The guiding assembly includes a guiding sleeve 61 and a bearing (not shown in the figure). Among them, the guiding sleeve 61 and the bearing are arranged at intervals along the axial direction of the stirring shaft 51.
