Description

Technical Field

[0001] This invention relates to the field of adhesive degassing devices, and more particularly to an ultrasonic vacuum centrifugal degassing device for adhesives. Background Technology

[0002] Dispensing is a common process in industrial production. Often, the glue in the glue container will absorb some air during prolonged storage. Because air bubbles are often present inside the glue, or in the dispensing machine's feed hopper, these bubbles and air can cause inconsistent glue dispensing amounts, or even result in products without glue, leading to low product yield. Therefore, the glue needs to be degassed before use.

[0003] Current degassing equipment is either structurally complex, has low degassing efficiency, or cannot prevent problems such as voids. Therefore, a more efficient degassing device is needed to degas the adhesive to meet the high precision requirements of dispensing operations. Summary of the Invention

[0062] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0063] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0064] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0065] See Figures 1 to 5 This invention provides an ultrasonic vacuum centrifugal degassing device for adhesives, comprising: an inner barrel 10, an outer barrel 20, a rotating assembly 30, and an ultrasonic vibration assembly 40. The inner barrel 10 is connected to a vacuum pump to extract air from the inner barrel 10, creating a vacuum. The outer barrel 20 is disposed outside the inner barrel 10 and has a vacuum connector 205 for connection to the vacuum pump. The rotating assembly 30 includes a motor 301 connected to the inner barrel 10 to drive the inner barrel 10 to rotate. The ultrasonic vibration assembly 40 includes an ultrasonic device 401, which drives the inner barrel 10 to perform ultrasonic vibration via the rotating assembly 30.

[0066] like Figures 1 to 5 As shown, to degas the adhesive, during use, the adhesive is injected into the inner barrel 10 through the inlet connector 206. After sealing the inner barrel 10, a vacuum device is used to extract the air from the inner barrel 10, creating a vacuum environment to better degas the adhesive inside. Simultaneously, the motor 301 within the rotating assembly 30 drives the inner barrel 10 to rotate. While the inner barrel 10 rotates, the ultrasonic device 401 simultaneously drives the inner barrel 10 to undergo ultrasonic vibration. During this process, the adhesive inside the inner barrel 10 undergoes centrifugal rotation and ultrasonic vibration, thereby breaking up air bubbles in the adhesive and achieving degassing. This reduces or even eliminates air bubbles in the adhesive, improving the accuracy of adhesive dispensing. Because this embodiment of the invention uses both vacuum centrifugal rotation and ultrasonic vibration, the air bubbles in the adhesive can be eliminated more thoroughly.

[0067] See Figures 2 to 5 The rotating assembly 30 further includes a motor connector 302, and the motor 301 is also connected to the outer barrel 20 via the motor connector 302. Figure 3 As shown, the lower end of the inner tub 10 is connected to the motor 301 of the rotating assembly 30 via an adhesive outlet. Thus, when the motor 301 rotates, it drives the inner tub 10 to rotate. The motor connector 302 is disposed between the inner tub 10 and the outer tub 20. The outer tub 20 can be fixedly connected to the motor 301, thereby allowing the inner tub 10 to be rotatably disposed inside the outer tub 20, providing some protection to the inner tub 10.

[0068] See Figures 3 to 5 The ultrasonic vibration assembly 40 further includes: a base 402, a floating connector 403, and a floating connecting plate 404. There is one or more floating connectors 403, and each floating connector 403 is fixedly connected to the base 402. The motor 301 and the ultrasonic device 401 are respectively mounted and fixed on the floating connecting plate 404, and are connected to the floating connector through the floating connecting plate 404.

[0069] like Figures 3 to 5 As shown, the ultrasonic vacuum centrifugal degassing device for the adhesive can be installed and fixed via the base 402. The ultrasonic devices 401 are respectively installed and fixed on the floating connecting plates 404. Thus, the ultrasonic devices 401 can drive the floating connecting plates 404 to vibrate synchronously. Since the floating connecting plates 404 are connected to the inner barrel 10 via the motor 301, the vibration of the floating connecting plates 404 under the action of the ultrasonic devices 401 can drive the motor 301 and the inner barrel 10 to vibrate simultaneously. This enables vibration degassing control of the adhesive in the inner barrel 10. Since the floating connecting plates 404 are floatingly connected to the base plate via one or more floating connectors 403, the floating connecting plates 404 can vibrate relative to the base 402 under the action of the ultrasonic devices 401.

[0070] See Figure 4 and Figure 5 The ultrasonic vacuum centrifugal degassing device for adhesives also includes a sealing and rotating connector 50, through which the inner barrel 10 is sealed and rotatably connected to the outer barrel 20. Figure 4 and Figure 5As shown, the inner tub 10 rotates at high speed under the control of the motor 301, causing the adhesive inside the inner tub 10 to undergo centrifugal rotation and degassing. The sealing and rotating connector 50 enables a sealed and rotatable connection between the inner tub 10 and the outer tub 20. This reduces the frictional resistance between the inner tub 10 and the outer tub 20, thereby minimizing heat generation caused by friction.

[0071] See Figure 4 and Figure 5 The ultrasonic vacuum centrifugal degassing device for adhesives further includes: a vacuum pressure sensor 60 and a vacuum breaking connector 202. The vacuum pressure sensor 60 is installed on the outer barrel 20 cover and is interconnected with the inner barrel 10 to detect the vacuum pressure of the inner barrel 10; the vacuum breaking connector 202 is installed on the outer barrel 20 cover and is interconnected with the inner barrel 10. Figure 4 and Figure 5 As shown, the vacuum pressure sensor 60 can detect the vacuum negative pressure of the inner barrel 10. Thus, the vacuuming equipment can control the vacuuming of the inner barrel 10 based on the detected vacuum negative pressure value, ensuring the purity of the defoamed adhesive. After defoaming, the inner barrel 10 can be connected to the external environment through the vacuum breaking connector 202, allowing the vacuum to be broken. This facilitates the removal and reuse of the defoamed adhesive.

[0072] See Figure 4 and Figure 5 The ultrasonic vacuum centrifugal degassing device for the adhesive includes: an adhesive dispensing assembly 70, which includes an adhesive dispensing connecting pipe 701. The adhesive dispensing connecting pipe 701 is connected to the inner barrel 10 to lead the adhesive from the inner barrel 10 to the outside. Figure 4 and Figure 5 As shown, the glue dispensing connection pipe 701 may be equipped with a manual control switch 706. When the glue has been defoamed and needs to be discharged for use, the glue dispensing channel can be opened by manually controlling the manual control switch 706, and the glue in the inner barrel 10 can be discharged to the outside through the glue dispensing connection pipe 701.

[0073] See Figure 4 and Figure 5The glue dispensing assembly 70 further includes a temperature detector 702, which is installed on the glue dispensing connecting pipe 701. The temperature detector 702 is used to detect the temperature of the glue in the inner bucket 10. The outer bucket 20 is also provided with a cooling connector 201, which is connected to the outside of the inner bucket 10 and is used to connect to a cooling device to control the cooling of the inner bucket 10 based on the temperature detection value of the temperature detector 702. Because the rotation of the inner bucket 10 causes the glue inside the inner bucket 10 to undergo centrifugal motion, a significant amount of heat is generated in the glue and the inner bucket 10, causing the inner bucket 10 to heat up. When the temperature is high, it is necessary to cool the inner bucket 10 and the glue inside it. The temperature detector 702 can detect the temperature of the adhesive inside the inner barrel 10. When a high temperature is detected, cooling gas can be output through the cooling device and delivered to the outer surface of the inner barrel 10 through the cooling connector 201 to cool the inner barrel 10. Cooling can be stopped when the temperature drops to near room temperature. This ensures that the adhesive inside the inner barrel 10 does not rise to an excessively high temperature.

[0074] See Figure 4 and Figure 5 The glue dispensing assembly 70 further includes a lower liquid level detector 703, which is installed on the glue dispensing connection pipe 701 and is used to detect the lower liquid level of the glue in the inner bucket 10. An upper liquid level detector 203 is also provided above the outer bucket 20, which is used to detect the upper liquid level of the glue in the inner bucket 10. Through the lower liquid level detector 703 and the lower liquid level detector, the glue in the inner bucket 10 and the glue dispensing connection pipe 701 can be detected. The amount of glue can be used to control whether glue needs to be injected into the inner bucket 10 or whether glue needs to be continuously discharged to the outside.

[0075] See Figure 4 and Figure 5 The glue dispensing assembly 70 further includes a liquid pump 704, which is connected to the glue dispensing connection pipe 701 to control the output of glue from the inner tank 10. The liquid pump 704 allows for the controlled discharge of glue when external discharge is required.

[0076] See Figure 4 and Figure 5The dispensing assembly 70 further includes a dispensing connector 705, which is connected to the output end of the liquid pump 704. The outer tank 20 is also equipped with a return connector 204, which is connected to the dispensing connector 705 via a connecting pipe. The dispensing connector 705 allows the glue to be connected to the dispensing container, discharging the glue externally and injecting it into the dispensing container for dispensing. Additionally, if the glue defoaming is insufficient, the glue can be returned to the inner tank 10 via the return connector 204 for further defoaming to meet high-precision dispensing requirements.
