[0004] The existing adhesive mixing devices mentioned above cannot perform pre-mixing before mixing, and one motor can only operate on one mixing tank, resulting in low overall efficiency. In addition, the mixing components adopt a sliding structure, which is prone to blockage at the sliding parts during the mixing process of adhesives, affecting the normal mixing process. Therefore, they do not meet the current requirements, and a new adhesive mixing device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device for adhesives, which solves the problems mentioned in the background art that existing adhesive stirring devices cannot perform pre-stirring before mixing, and one motor can only stir one mixing tank, resulting in low overall efficiency. In addition, the stirring components adopt a sliding structure, which can easily cause blockage at the sliding parts during the stirring process of adhesives, affecting the normal stirring process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for adhesives, comprising: a pre-mixing tank, a heated mixing tank, a first mixing element, and a second mixing element. The heated mixing tank is installed below the pre-mixing tank. The first mixing element and the second mixing element are respectively installed inside the pre-mixing tank and the heated mixing tank. A servo motor is installed above the first mixing element. The first mixing element and the second mixing element are connected by a coupling.

[0007] Preferably, the first stirring component includes a first stirring shaft, and a plurality of first stirring blades arranged in a ring at intervals are provided on the outer wall of the first stirring shaft. Multiple sets of the first stirring blades are installed at intervals above and below. An L-shaped stirring frame that fits the shape of the inner cavity of the pre-stirring tank is also installed on the outer wall of the first stirring shaft. A push scraper with an inclination is provided at the bottom of the L-shaped stirring frame.

[0008] Preferably, the heating and stirring tank includes an outer heating sleeve and an inner stirring tank, with the outer heating sleeve disposed outside the inner stirring tank.

[0009] Preferably, the second stirring component includes a second stirring shaft installed inside the inner stirring tank, a plurality of annularly spaced stirring supports are installed on the outer wall of the second stirring shaft, the shape of the stirring supports fits the inner stirring tank, a plurality of second stirring blades are provided on the inner side wall of the stirring supports, and a plurality of annularly spaced third stirring blades are installed near the bottom of the second stirring shaft.

[0010] Preferably, a second control valve is installed at the bottom of the inner mixing tank, and a discharge pipe is installed below the second control valve, with one end of the discharge pipe extending to the outside of the outer heating jacket.

[0011] Preferably, an assembly assembly is installed between the pre-mixing tank and the heating mixing tank. The assembly assembly includes an annular assembly frame installed at the bottom of the pre-mixing tank, and multiple sets of annularly spaced support frames installed below the annular assembly frame. Multiple sets of annularly spaced assembly seats are installed on the outer walls of both the pre-mixing tank and the heating mixing tank.

[0012] Preferably, the pre-mixing tank is provided with a feed inlet at the top and a discharge outlet at the bottom, and a first control valve is installed between the discharge outlet and the inlet of the heating mixing tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the pre-mixing tank and the heating mixing tank are arranged in upper and lower layers. The pre-mixing tank contains a first stirring component, and the heating mixing tank contains a second stirring component. The first stirring component is driven by a servo motor to rotate and perform stirring and mixing operations in the pre-mixing tank. The first stirring component and the second stirring component are connected by a coupling so that when the first stirring component rotates, the second stirring component also rotates. This achieves the effect of stirring the two tanks by one motor, effectively improving the stirring efficiency and enabling the adhesive to be fed into the heating mixing tank for heating and stirring operations after pre-mixing.

[0015] (2) In this utility model, the first stirring component mixes the contents of the bucket through multiple first stirring blades during the stirring process, and rotates against the bucket wall through an L-shaped stirring frame. During its rotation, the bottom scraper pushes and scrapes the bottom of the bucket, making it less likely to accumulate at the bottom and improving the mixing effect. The second stirring component rotates inside the inner mixing bucket through a stirring bracket. Because it fits the shape of the bucket, it can scrape the mixture hanging on the wall during the stirring process. During the rotation of the stirring bracket, several second stirring blades stir the inside at the same time, and the bottom discharge port is stirred by a third stirring blade. The above structure effectively improves the stirring range, improves the matching degree between the bucket and the stirring component, and effectively improves the stirring effect. The above stirring components have different structures, which can fit different buckets. They are an integral structure, making the whole more stable and less susceptible to the influence of sticky substances. Attached Figure Description

The heated mixing tank 2 is installed below the pre-mixing tank 1. The first mixing element 4 and the second mixing element 7 are respectively installed inside the pre-mixing tank 1 and the heated mixing tank 2. A servo motor 5 is installed above the first mixing element 4. The first mixing element 4 and the second mixing element 7 are connected by a coupling 6.

[0025] The pre-mixing tank 1 and the heating mixing tank 2 are arranged in an upper and lower level. The pre-mixing tank 1 contains a first stirring element 4, and the heating mixing tank 2 contains a second stirring element 7. The first stirring element 4 is driven by a servo motor 5 to rotate and perform a mixing operation in the pre-mixing tank 1. The first stirring element 4 and the second stirring element 7 are connected by a coupling 6, so that when the first stirring element 4 rotates, the second stirring element 7 also rotates. This achieves the effect of driving the two tanks to stir with one motor, which effectively improves the stirring efficiency and allows the adhesive to be fed into the heating mixing tank 2 after pre-mixing for heating and stirring.

[0026] Please see Figure 2 , Figure 3 , Figure 5The pre-mixing tank 1 has a feed inlet 101 at the top and a discharge port 102 at the bottom.
