Description

Technical Field

[0001] This utility model relates to a mixing and storage tank for coated adhesive, belonging to the field of adhesive processing. Background Technology

[0002] When assembling electronic components in mobile phones, tablets, or computers, a layer of double-sided tape needs to be applied to the back of the components. Additionally, to achieve insulation, vibration damping, sealing, and dustproofing, some electronic components also require foam attachment to the back. During the production of protective films for electronic products, a uniform and reliable layer of adhesive needs to be coated onto the film surface. Therefore, the adhesive needs to be stirred before coating to ensure its uniformity. However, currently, a large amount of adhesive is directly added to the mixing drum during the mixing process, resulting in prolonged mixing time and low efficiency. Summary of the Invention

At least one annular support is arranged inside the tank and on the outside of the circular shell. Each annular support has several cutting blades installed on its inner wall, corresponding to the discharge holes on the circular shell. The inclined direction of the cutting blades forms an acute angle with the axial direction of the corresponding annular support, so that the inclined direction of each cutting blade intersects with the discharge direction of the corresponding discharge hole.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, a second motor is installed on the top surface of the outer side of the tank and directly above the rotating shaft. The lower end of a drive shaft whose upper end is connected to the output shaft of the second motor is rotatably connected to the top of the circular shell. The upper end of a support frame disposed in the tank is connected to the drive shaft and can rotate accordingly. The lower end of the support frame is rotatably fitted onto the outside of the conveying pipe. The annular brackets are respectively installed on the support frame and can rotate accordingly. The rotation direction of the second motor is opposite to that of the first motor.

[0008] 2. In the above scheme, the drive shaft and the circular housing, the circular housing and the material conveying pipe, and the material conveying pipe and the lower end of the support frame are each rotatably connected by a bearing.

[0025] Example 2: A mixing and storage tank for coated adhesive, comprising a tank body 100 having an inlet 101 and an outlet 102 respectively. A conveying pipe 1 is vertically arranged in the central area of ​​the tank body 100. The upper end of the conveying pipe 1, which is sealed to the inner wall of the bottom of the tank body 100, is equipped with a circular shell 2 that communicates with the conveying pipe 1. The lower end of a rotating shaft 3, which is concentrically arranged in the conveying pipe 1, is connected to the output shaft of a first motor 4 installed on the outer bottom surface of the tank body 100. The upper end of the rotating shaft 3 is connected to the circular shell 2 and is used to drive the circular shell 2 to rotate. A plurality of feed through holes 51 are provided on the side wall of the lower end of the conveying pipe 1.

[0026] The circular shell 2, which is concentrically arranged with the tank body 100, has a plurality of circumferentially spaced discharge holes 52 on its side wall. Each discharge hole 52 is inclined, so that the discharge direction of each discharge hole 52 forms an acute angle with the axial direction of the corresponding circular shell 2.

[0027] A spiral blade 6 is wound around the outer surface of the aforementioned rotating shaft 3 located in the inner region of the conveying pipe 1; a pump body is installed at one end of the aforementioned conveying pipe 1 near the circular shell 2 for transporting fluid from the lower part of the tank 100 to the circular shell 2, wherein the fluid is glue containing particulate filler.

[0028] The upper end of the aforementioned rotating shaft 3 is fixedly connected to the top surface of the circular housing 2 via a connecting shaft 7 disposed inside the circular housing 2.

[0029] The bottom of the tank 100 is equipped with at least three support feet 103 arranged circumferentially; the aforementioned feed holes 51 are arranged at equal intervals circumferentially, and each feed hole 51 is a strip-shaped through hole extending axially along the conveying pipe 1.

[0031] Working principle:

[0032] Before applying the adhesive layer to the membrane material, the adhesive is first stirred to ensure its uniformity during dispensing, thereby ensuring the uniformity of the coating effect.

[0033] The glue is injected into the tank through the inlet 101 and falls to the bottom of the tank. It then enters the conveying pipe 1 through the inlet 51 at the lower end of the conveying pipe 1. The first motor 4 drives the rotating shaft 3 to rotate the spiral blades 6. The glue in the conveying pipe 1 is lifted upward into the circular shell 2 by the rotating spiral blades. The first motor 4 drives the circular shell 2 to rotate, and the glue transported to the circular shell 2 is thrown outward with force through several outlet holes 52 on its side wall and hits the rotating cutting blade 12 on its outside before flowing downward. During this process, the second motor 8 drives the support frame 10 to rotate the cutting blade 12 on the ring support 11. By circulating the glue and increasing the cutting and collision of the glue during the circulating fall, the uniformity and efficiency of the glue mixing are improved.

[0034] By controlling the rotation of the circular housing 2 and the cutting blade 12 by the first motor 4 and the second motor 8 respectively, their opposite rotation can be achieved. Combined with their respective tilt settings, the collision strength and effectiveness between the glue ejected after circulation and the cutting blade are further improved, thereby further enhancing the mixing effect of the glue.

[0035] When using the above-mentioned coating adhesive mixing and storage tank, it can not only achieve full mixing of multi-component materials in the fluid by circulating the fluid in the tank, but also increase the cutting and collision of the fluid during the process of the adhesive circulating and falling, and improve the collision strength and effectiveness between the ejected fluid and the cutting blade, thereby further improving the uniformity and mixing effect of the fluid.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
