Description

Technical Field

[0001] This invention belongs to the field of adhesive treatment technology, specifically relating to a rapid defoaming device for adhesives. Background Technology

[0002] In the adhesive coating and potting industry, air bubbles in the adhesive are a significant factor affecting product quality. Excessive air bubbles in the adhesive can impair its curing process, thereby affecting its sealing, flame-retardant, insulating, waterproof, and shock-resistant properties. This ultimately reduces product yield during production, leading to economic losses for the company. Therefore, it is essential to remove air bubbles from the adhesive before coating and potting.

[0003] Currently, most glue degassing devices on the market employ one of two main degassing methods: Vacuum degassing: The container filled with glue is evacuated and maintained at this vacuum for a certain period, allowing air bubbles to rise to the liquid surface under the pressure difference, followed by slow degassing. Stirring degassing: Stirring is performed under vacuum to promote glue flow and ensure uniform degassing. However, this method also has drawbacks such as incomplete degassing, excessively long degassing preparation time, and the inability to monitor the degassing process in real time. Summary of the Invention

By opening multiple defoaming holes on the flow guide, the adhesive is concave downward under the action of gravity when passing through the defoaming holes, and the thickness of the adhesive is further reduced after stretching. At the same time, the lower surface of the adhesive is exposed to the vacuum environment, making it easier for the adhesive to escape, thereby further improving the defoaming efficiency of the adhesive.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The rapid defoaming device for adhesive according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown, the glue rapid defoaming device according to an embodiment of the present invention includes: a container and a stirring device 10. The container is filled with glue. The stirring device 10 is disposed in the container and is used to stir the glue. The stirring device 10 has a flow guide, and the glue flows in a thin film on the flow guide. The flow guide has a plurality of defoaming holes 168. When the glue passes through the defoaming holes 168, the thickness of the glue decreases, thereby causing the air bubbles in the glue to escape.

[0029] The beneficial effects of this invention are that by setting a stirring device 10 inside the container and a flow guide on the stirring device 10, the adhesive can flow in a thin film on the flow guide during stirring, which increases the contact area between the upper surface of the adhesive and the vacuum environment, while reducing the thickness of the adhesive, making it easier for the adhesive to escape. By opening multiple defoaming holes 168 on the flow guide, the adhesive is depressed downward under the action of gravity when passing through the defoaming holes 168, and the thickness of the adhesive is further reduced after stretching. At the same time, the lower surface of the adhesive is exposed to the vacuum environment, making it easier for the adhesive to escape, thereby further improving the defoaming efficiency of the adhesive.

[0030] According to one embodiment of the present invention, the defoaming hole 168 is a through hole. When the defoaming hole 168 is a through hole, the lower surface of the adhesive can be exposed to a vacuum environment when the adhesive passes through the defoaming hole 168. The size of the defoaming hole 168 is related to the viscosity of the adhesive. By setting an appropriately sized defoaming hole 168, it is ensured that the adhesive does not drip from the defoaming hole 168.

[0031] like Figure 4 As shown, this is the first structure of the flow guide, which includes an upper screen cover 164 and a lower screen cover 165. The diameter of the outer circumferential surface of the upper screen cover 164 gradually increases from top to bottom. The lower screen cover 165 is located below the upper screen cover 164, and the diameter of the inner circumferential surface of the lower screen cover 165 gradually decreases from top to bottom. The projection of the upper screen cover 164 in the height direction falls on the inner circumferential surface of the lower screen cover 165. The adhesive flows in a thin film on the outer circumferential surface of the upper screen cover 164 and the inner circumferential surface of the lower screen cover 165. The adhesive flows from the outer circumferential surface of the upper screen cover 164 to the inner circumferential surface of the lower screen cover 165. Furthermore, the flow guide also includes: an outer cover 166, which is vertically disposed inside the container. The inner periphery of the upper screen cover 164 and the inner periphery of the lower screen cover 165 are connected to the outer periphery of the outer cover 166. The outer cover 166 has multiple overflow holes 167 extending through the wall thickness direction. The multiple overflow holes 167 are arranged circumferentially around the outer cover 166. The overflow holes 167 are located above the upper screen cover 164. The glue flows from the inside of the outer cover 166 through the overflow holes 167 to the outer periphery of the upper screen cover 164. The inner periphery of the lower screen cover 165 has holes at the connection with the outer cover 166. The glue flows from the inner periphery of the lower screen cover 165 through the holes to the outer periphery of the outer cover 166.

[0032] In other words, such as Figure 4 As shown, the outer surface of the upper screen cover 164 is formed into a conical surface, and the inner surface of the lower screen cover 165 is formed into an inverted conical surface. The inner peripheral diameter of the upper edge of the lower screen cover 165 is larger than the outer peripheral diameter of the lower edge of the upper screen cover 164. In this way, when the glue flows downward on the outer surface of the upper screen cover 164, it can fall on the inner surface of the lower screen cover 165, thereby performing defoaming twice and improving the defoaming effect.

[0033] like Figure 5As shown, this is the second structure of the flow guide, which includes an upper screen cover 164 and a lower screen cover 165. The diameter of the outer circumferential surface of the upper screen cover 164 gradually increases from top to bottom. The lower screen cover 165 is located below the upper screen cover 164, and the diameter of the outer circumferential surface of the lower screen cover 165 gradually increases from top to bottom. The maximum outer diameter of the upper screen cover 164 is greater than the maximum outer diameter of the lower screen cover 165. The adhesive flows in a thin film on the outer circumferential surfaces of the upper screen cover 164 and the lower screen cover 165. Furthermore, the flow guide also includes: an outer cover 166, which is vertically disposed inside the container. The inner periphery of the upper screen cover 164 and the inner periphery of the lower screen cover 165 are both connected to the outer periphery of the outer cover 166. The outer cover 166 is provided with a plurality of overflow holes 167 extending through the wall thickness direction. The plurality of overflow holes 167 are arranged circumferentially along the outer cover 166. The overflow holes 167 are located above the lower screen cover 165. The glue flows from inside the outer cover 166 through the overflow holes 167 to the outer periphery of the upper screen cover 164 and the outer periphery of the lower screen cover 165.

[0034] In other words, such as Figure 5 As shown, the outer surfaces of the upper screen cover 164 and the lower screen cover 165 are both formed as conical surfaces. The outer periphery of the lower edge of the upper screen cover 164 is larger than the outer periphery of the lower edge of the lower screen cover 165. Therefore, the glue falling from the upper screen cover 164 and the glue falling from the lower screen cover 165 do not interfere with each other.

[0035] According to one embodiment of the present invention, a plurality of defoaming holes 168 are arranged in a circular array on the upper screen cover 164 and the lower screen cover 165. The glue contacts the defoaming holes 168 more evenly, thus resulting in better glue defoaming effect.

[0036] Preferably, the container includes: a material cylinder 1 and a cover plate 2. The material cylinder 1 is a cylindrical part with an upper opening; the cover plate 2 is placed on the material cylinder 1 to open or close the upper opening. The material cylinder 1 and the cover plate 2 are detachable and are sealed together, thereby facilitating the formation of a vacuum environment inside the material cylinder 1.

[0037] According to one embodiment of the present invention, the stirring device 10 includes: a motor 13, a reducer 14, a bearing seat 15, and a stirring and degassing component 16. The motor 13 is located above the cover plate 2. The input end of the reducer 14 is connected to the output end of the motor 13, and the output end of the reducer 14 passes through the cover plate 2. The bearing seat 15 is sleeved on the output end of the reducer 14 and is connected to the cover plate 2. The stirring and degassing component 16 is located inside the material cylinder 1 and is connected to the output end of the reducer 14.

[0038] According to one embodiment of the present invention, the stirring and degassing component 16 includes: a drive shaft 161 and a stirring blade 163. The drive shaft 161 is vertically disposed in the middle of the material cylinder 1, and the upper end of the drive shaft 161 is connected to the output end of the reducer 14. The stirring blade 163 is connected to the lower end of the drive shaft 161, and the lower surface of the stirring blade 163 is in contact with the inner bottom surface of the material cylinder 1. The stirring blade 163 can agitate the glue at the bottom of the material cylinder 1, thereby making the glue inside the entire material cylinder 1 flow and improving the uniformity of degassing.

[0039] According to one embodiment of the present invention, an outer cover 166 is sleeved on a drive shaft 161, and the outer cover 166 and the drive shaft 161 are coaxially arranged. A spiral blade 162 is provided between the outer cover 166 and the drive shaft 161. The inner edge of the spiral blade 162 is connected to the drive shaft 161, and the outer edge of the spiral blade 162 is connected to the outer cover 166. When the drive shaft 161 rotates, the adhesive moves spirally along the spiral blade 162 to the overflow hole 167. In other words, the spiral blade 162 forms a spiral upward channel between the outer cover 166 and the drive shaft 161. When the spiral blade 162 rotates, it causes the adhesive to spiral upward, thereby lifting the adhesive at the bottom to defoam and thus realizing the circulation and defoaming of the adhesive.

[0040] In some preferred embodiments of the present invention, the glue rapid defoaming device further includes: a feeding component 3, a reflux component 4, a guide plate 12, and a discharge port 11. The feeding component 3 is disposed on the cover plate 2, and the lower end of the feeding component 3 is connected to the material cylinder 1. The reflux component 4 is disposed on the cover plate 2, and the lower end of the reflux component 4 is connected to the material cylinder 1. One end of the guide plate 12 is connected to the lower surface of the cover plate 2, and the other end of the guide plate 12 is inclined downward and points towards the upper screen cover 164. The lower ends of the feeding component 3 and the lower ends of the reflux component 4 are both facing the upper surface of the guide plate 12. After the glue is spread thinly on the upper surface of the guide plate 12, it flows to the outer peripheral surface of the upper screen cover 164. The discharge port 11 is disposed at the bottom of the material cylinder 1, and a portion of the glue flowing out from the discharge port 11 flows to the reflux component 4.

[0041] In other words, the feeding component 3 can be a feeding pipe with a valve. When the barrel 1 is in a vacuum environment, it can automatically draw external glue into the barrel 1. The glue discharged from the outlet 11 can re-enter the barrel 1 through the return component 4. After entering the barrel 1, the glue first falls on the guide plate 12. The glue will spread and extend along the guide plate 12 and fall on the outer circumferential surface of the upper screen cover 164 along the inclined direction of the guide plate 12, rather than falling on the bottom of the barrel 1. In this way, the glue will be degassed immediately after entering the barrel 1.

[0042] According to one embodiment of the present invention, the cover plate 2 is provided with a pressure relief device 7, a vacuum gauge 8, and an observation component 9. The vacuum gauge 8 is used to detect the vacuum level inside the material cylinder 1, the pressure relief device 7 is used to introduce air into the material cylinder 1 to adjust the vacuum level, and the observation component 9 consists of an observation window and a camera, the camera being used to photograph the state of the adhesive inside the material cylinder 1. That is, the pressure relief device 7 has a solenoid valve or a ball valve, and the amount of external air entering the material cylinder 1 is controlled by controlling the opening and closing of the solenoid valve or ball valve. The feeding component 3, the return component 4, the pressure relief device 7, the vacuum gauge 8, the observation component 9, and the stirring device 10 are all integrated on the cover plate 2, making the structure more compact.

[0043] According to one embodiment of the present invention, a high liquid level sensor 5 and a low liquid level sensor 6 are provided on the material cylinder 1. The high liquid level sensor 5 is located on the side of the material cylinder 1 and flush with the lower edge of the upper screen cover 164, while the low liquid level sensor 6 is located at the bottom of the material cylinder 1. The high liquid level sensor 5 can prevent the glue level from exceeding the lower edge of the upper screen cover 164, thereby preventing the defoaming function of the upper screen cover 164 from failing. The low liquid level sensor 6 can trigger an alarm when the glue level is insufficient, thereby replenishing the glue level.
