Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically to an adhesive storage tank. Background Technology

[0002] As is generally known, a capsule glue storage tank is a glue storage device that connects the glue tank and the pelletizing machine.

[0003] For example, the utility model patent with application publication number CN215206544U, application publication date of December 17, 2021, and titled "A Soft Capsule Liquid Storage Tank", has the following specific structure: a tank body, a guide tube inside the tank body, a first defoaming needle on the inner wall of the guide tube, a buffer chamber at the bottom of the tank body, a liquid outlet on the buffer chamber, the bottom end of the guide tube extending into the interior of the buffer chamber, and a defoaming screen at the bottom end of the guide tube. The defoaming screen is rotatably connected to the bottom end of the guide tube via a rotating seat. A second defoaming needle is connected to the upper end of the defoaming screen, and a rotating shaft is connected to the lower end of the defoaming screen. The rotating shaft movably passes through the tank body and is connected to a motor.

[0004] The shortcoming of the existing technology is that it uses a guide tube to introduce the glue into the tank for storage. The end of the guide tube is located in the tank and has a buffer chamber. The glue flows into the tank from the outlet of the buffer chamber. The top of the buffer chamber has a closed space. When there are air bubbles in the glue, the air bubbles are easily affected by buoyancy and float to the top of the buffer chamber and stagnate on the outer periphery of the guide tube. This makes it difficult to remove the air bubbles. The presence of air bubbles in the glue stagnating on the outer periphery of the guide tube will still affect the quality of the capsules produced later. Utility Model Content

[0005] The purpose of this invention is to provide an adhesive storage tank to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adhesive storage tank, comprising a tank body and an inlet pipe connected thereto, wherein the interior of the tank body is provided with a conical annular guide surface, the narrow end of the guide surface being the low end, and the inlet pipe being provided with an arc-shaped portion, the arc-shaped portion being coaxially arranged with the guide surface so that the adhesive flows along the tangential direction of the guide surface to form a vortex.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-4 This utility model provides a technical solution: Example 1 Combination Figure 1 and Figure 2 As shown, this embodiment adds a defoaming structure to the original storage tank. The arc-shaped part 21 of the liquid inlet pipe 2 is arranged coaxially with the conical annular guide surface 11 inside the tank body 1. When the adhesive is filled into the tank body 1 through the liquid inlet pipe 2, the adhesive flows out along the arc-shaped part 21 and flows along the tangential direction of the guide surface 11 to the guide surface 11. Under the influence of inertia and gravity, the adhesive continues to flow in an annular shape along the guide surface 11 to form a vortex. During the annular flow of the adhesive, the air bubbles contained in the adhesive tend to float to the middle of the adhesive vortex and be discharged from the adhesive. The centrifugal flow of the adhesive removes the air bubbles in the adhesive and also prevents the air bubbles from adhering and stagnating on the periphery of the arc-shaped part 21 of the liquid inlet pipe 2, thereby improving the stability of air bubble removal in the adhesive.

[0022] Specifically, such as Figure 2 As shown, a conical annular guide surface 11 is provided inside the tank body 1, and a drain pipe 3 is also provided on the tank body 1. The drain pipe 3 is connected to the lower end of the guide surface 11, and the lower end of the guide surface 11 is the drain port 111. That is, the drain pipe 3 is located at the narrow opening of the guide surface 11, thereby reducing the probability of bubbles flowing into the drain pipe 3 with the adhesive and further increasing the bubble content of the discharged adhesive.

[0023] When the adhesive is filled into the tank 1 through the inlet pipe 2, the adhesive flows out along the arc-shaped part 21 and flows along the tangential direction of the guide surface 11 to the guide surface 11. Under the influence of inertia and gravity, the adhesive continues to flow in a ring along the guide surface 11 to form a vortex. During the ring flow of the adhesive, the air bubbles contained in the adhesive tend to float to the middle of the adhesive vortex and be discharged outside the adhesive.

[0024] In the above technical solution, by utilizing the arc-shaped portion 21 of the liquid inlet pipe 2 and the guide surface 11 of the tank body 1, the adhesive liquid can flow in a ring along the guide surface 11 after flowing out from the arc-shaped portion 21 to form a vortex. The air bubbles contained in the adhesive liquid can easily float to the center of the adhesive liquid vortex and be discharged outside the adhesive liquid, which effectively improves the stability of air bubble removal in the adhesive liquid and also prevents air bubbles from adhering and stagnating on the periphery of the arc-shaped portion 21 of the liquid inlet pipe 2, thereby improving the stability of air bubble removal in the adhesive liquid.

[0025] Example 2 Combination Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides an additional flow guiding component based on Embodiment 1. That is, the rotating ring 4. When the adhesive flows out along the arc-shaped portion 21 and flows along the tangential direction of the flow guiding surface 11 onto the flow guiding surface 11, the adhesive will flow and impact the extension plate 41 of the rotating ring 4 to drive the rotating ring 4 to rotate in a cycle. This allows the rotating ring 4 and the extension plate 41 to rotate within the adhesive to balance the circumferential flow of the vortex formed by the adhesive, reducing the problem of bubble introduction caused by the velocity difference at different positions of the vortex.

[0026] Specifically, such as Figure 2 As shown, the rotating ring 4 is rotatably disposed inside the tank 1 and rotates coaxially with the guide surface 11. When the adhesive flows out along the arc-shaped part 21 and flows along the tangential direction of the guide surface 11 to the guide surface 11, the adhesive will flow and impact the extension plate 41 of the rotating ring 4 to drive the rotating ring 4 to rotate in a cycle. This allows the rotating ring 4 to rotate in a cycle within the adhesive in the tank 1. The extension plates 41 are used to balance the flow velocity of the adhesive vortex at various circumferential locations, thereby improving the forming stability of the adhesive vortex and reducing the problem of bubble introduction caused by the flow velocity difference at different locations of the vortex.

[0027] Example 3 Combination Figure 3 As shown, this embodiment further optimizes the extension plate 41 based on embodiment two. The ball groove 43 opened on the extension plate 41 increases the impact force of the adhesive sprayed from the arc-shaped part 21 on the extension plate 41, thereby solving the problem of the adhesive impact driving the rotating ring 4 to rotate.

[0028] Specifically, the rotating ring 4 is driven to rotate so that the ball grooves 43 on the several extension plates 41 rotate sequentially to the end facing the arc-shaped part 21. When the arc-shaped part 21 sprays the adhesive onto the guide surface 11, the adhesive impacts the extension plates 41 and causes some of the adhesive to fill into the ball grooves 43. The air bubbles contained in the adhesive follow the adhesive and impact the ball grooves 43, thereby causing the air bubbles to break into smaller air bubbles due to the reaction force of the impact, thus facilitating the elimination of air bubbles.

[0029] Example 4 Combination Figure 2 and Figure 3 As shown, this embodiment further optimizes the extension plate 41 based on embodiment two. A plurality of needles 42 are provided on the extension plate 41. When the adhesive flows out from the arc-shaped portion 21 to the guide surface 11, the adhesive impacts the extension plate 41 to contact the needles 42, thereby using the needles 42 to puncture large air bubbles contained in the adhesive. This allows the large air bubbles to break and reduce their size, facilitating the subsequent separation and elimination of bubbles by the adhesive vortex.

[0030] Specifically, such as Figure 3 As shown, several needles 42 are welded and fixed to the extension plate 41, and the rotating ring 4 is driven to rotate so that the needles 42 on the extension plate 41 move in sequence and toward the end of the arc-shaped part 21, so that the needles 42 can break the air bubbles contained in the flowing glue.

[0031] The needles 42 are arranged in a circular array to balance the spacing between them, thereby further improving the efficiency of the needles 42 in breaking up air bubbles in the adhesive.

[0032] Example 5 Combination Figure 3 and Figure 4 As shown, this embodiment further optimizes the rotating ring 4 based on embodiment two. The rotating ring 4 has several inner grooves 44, which are used to further improve the effect of the rotating ring 4 in balancing the flow rate of the adhesive vortex in all circumferential directions.

[0033] Specifically, the inner groove 44 on the rotating ring 4 is arranged at intervals with the extension plate 41. When the adhesive flows in a ring along the guide surface 11 to form an adhesive vortex, the rotating ring 4 rotates synchronously with the adhesive vortex to pass through the extension plate 41 and the inner groove 44 to balance the flow velocity of the adhesive vortex at various circumferential points, thereby improving the forming stability of the adhesive vortex and reducing the problem of bubble introduction caused by the flow velocity difference at different positions of the vortex.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
