[0019] Specific embodiments of the adhesive mixing device involved in this utility model are as follows: Figures 1-7The system includes a support frame 1 as its foundation, which consists of a support plate and support legs. The support plate of the support frame 1 has a through-hole 17. A mixing tank 2, extending through the support plate, is mounted on the support frame 1 via the support hole 17. A support ring 18 protrudes from the mixing tank 2, with an outer diameter larger than the diameter of the support hole 17. The lower surface of the support ring 18 presses against the support plate of the support frame 1, thus supporting the mixing tank 2 on the support frame 1. The mixing tank 2 has a mixing chamber for containing adhesive raw materials. The upper and lower ends of the mixing tank 2... The mixing tank 2 is equipped with an inlet and an outlet, which are the upper and lower ports of the mixing chamber, respectively. An upper cover 3 is fitted to the inlet of the mixing tank 2 to prevent rotation. An anti-rotation block protrudes from the outer wall of the mixing tank 2 at the end where the inlet is located. An anti-rotation groove is formed on the upper cover 3 to mate with the anti-rotation block. The upper cover 3 is fitted to the inlet of the mixing tank 2 to prevent rotation through the engagement of the anti-rotation block and the anti-rotation groove. An agitator is mounted on the upper cover 3, driven by a power mechanism. The agitator extends into the interior of the mixing tank 2 and is used to agitate the viscous material in the mixing tank 2. The mixture contains raw materials, ensuring uniform mixing of all components. It also includes a peristaltic pump 4, which has a pump head and a pump tube 5. The pump head of the peristaltic pump 4 is equipped with a rotor, and the pump tube 5 is an elastic tube. When the rotor rotates on the pump head, it squeezes the pump tube 5, drawing fluid into the pump tube 5 and transporting the fluid through it. An installation strip 6 protrudes from the outer wall of the mixing tank 2, and an installation groove 9 is formed on the installation strip 6. A fixing block 7 protrudes from the pump head of the peristaltic pump 4, and the fixing block 7 is inserted into the installation groove 9 on the installation strip 6, with the fixing block 7 and the installation groove 9 tightly fitted together. The pump head of the peristaltic pump 4 is fixed to the outer wall of the mixing tank 2 via the mounting groove 9 on the mounting strip 6 and the fixing block 7. The upper cover 3 is provided with a return channel connected to the feed inlet of the mixing tank 2, which is also connected to the mixing chamber of the mixing tank 2. A guide hopper 8 is fixedly installed at the discharge outlet of the mixing tank 2. The upper end of the pump pipe 5 is fixedly inserted into the return channel via a first fastening device, and the lower end of the pump pipe 5 is sealed and fitted onto the guide hopper 8 via a second fastening device. The peristaltic pump 4 is used to lift the adhesive material in the mixing tank 2 from bottom to top. The guide hopper 8 is used to guide the material at the bottom of the mixing tank 2 to the lower end of the pump pipe 5, and the peristaltic pump 4 is used to lift this part of the material, allowing it to flow back into the mixing chamber of the mixing tank 2 via the return channel.

[0020] In use, firstly, the lower end of the pump pipe 5 of the peristaltic pump 4 is sealed and fitted onto the guide hopper 8 using the second fastening device. Then, the upper cover 3 is opened, and the adhesive raw material to be mixed is put into the mixing tank 2. After that, the upper end of the pump pipe 5 is inserted into the return channel of the upper cover 3 and fixed with the first fastening device. Then, the power mechanism and the peristaltic pump 4 are started respectively. The power mechanism drives the agitator to rotate in the mixing tank 2, thereby mixing the adhesive raw material in the mixing tank 2. The peristaltic pump 4 draws in the adhesive raw material from the bottom of the mixing tank 2 and conveys it upward. This adhesive raw material flows back into the mixing tank 2 through the return channel on the upper cover 3. In this way, the adhesive raw material in the mixing tank 2 circulates from bottom to top, thereby making the adhesive raw material in the mixing tank 2 more evenly mixed.

[0021] Specifically, the return channel is a guide pipe 10 fixedly installed on the upper cover 3. The guide pipe 10 is connected to the mixing chamber of the mixing tank 2. The upper end of the guide pipe 10 is higher than the upper surface of the upper cover 3, so that the upper opening of the guide pipe 10 is above the upper cover 3, preventing dust and other debris on the upper cover 3 from entering the mixing tank 2 through the upper opening of the guide pipe 10.

[0022] Specifically, the first fastening device is a limiting ring 11 fixedly installed on the pump pipe 5. The limiting ring 11 has a limiting groove 19 that mates with the upper end of the guide pipe 10. The limiting groove 19 is tightly fitted with the upper end of the guide pipe 10. When the upper end of the pump pipe 5 is inserted into the guide pipe 10, the limiting ring 11 can fix the upper end of the pump pipe 5 in the guide pipe 10 and limit the length of the pump pipe 5 extending into the guide pipe 10 and the mixing tank 2, preventing the pump pipe 5 from extending into the movement path of the mixing components and interfering with the movement of the mixing components.

[0023] Specifically, the upper end of the pump pipe 5 is not lower than the lower end of the guide pipe 10. In this way, the outer wall of the pump pipe 5 does not come into contact with the adhesive material in the mixing tank 2, thus preventing contamination of the adhesive material.

[0024] Specifically, the lower end of the guide pipe 10 extends into the interior of the mixing tank 2, and the guide pipe 10 does not interfere with the rotation of the mixing components. The lower end of the guide pipe 10, which extends into the interior of the mixing tank 2, serves to guide the flow of the adhesive raw materials flowing out from the upper end of the pump pipe 5. These adhesive raw materials will flow directly downward into the mixing tank 2 without adhering to the upper cover 3 or the inner wall of the mixing tank 2 and interfering with the mixing.

[0025] Specifically, the second fastening device is a spring clamp 12. After the lower end of the pump pipe 5 is fitted onto the guide hopper 8, the spring clamp 12 is engaged at the overlap between the lower end of the pump pipe 5 and the guide hopper 8, thereby achieving a sealed fit between the two; and the spring clamp 12 makes the lower end of the pump pipe 5 more securely fitted onto the guide hopper 8, preventing the lower end of the pump pipe 5 from falling off the guide hopper 8 during operation.

[0026] Specifically, the mixing components include a central mixing rod 13 and an edge mixing frame 14 mounted on the central mixing rod 13 to prevent rotation. When the central mixing rod 13 rotates, it drives the edge mixing frame 14 to rotate as well. The central mixing rod 13 is equipped with a stirring paddle for stirring the adhesive material from the center of the mixing chamber of the mixing tank 2; the edge mixing frame 14 is also equipped with a stirring paddle for stirring the adhesive material from the edge of the mixing chamber of the mixing tank 2. The cooperation between the central mixing rod 13 and the edge mixing frame 14 improves the mixing efficiency.

[0027] Specifically, a scraper 15 is provided on the edge stirring frame 14, and the free end of the scraper 15 is attached to the inner wall of the mixing tank 2. When the edge stirring frame 14 rotates, the scraper 15 rotates with it, thereby continuously scraping the inner wall of the mixing tank 2 to clean the adhesive material adhering to the inner wall of the mixing tank 2, and to prevent the adhesive material from adhering to the inner wall of the mixing tank 2 and affecting the uniformity of mixing.

[0028] Specifically, the power mechanism is a motor 16. The upper cover 3 has a mounting through hole, the central stirring rod 13 is rotatably assembled in the mounting through hole, the outer shell of the motor 16 is fixed on the upper cover 3, and the rotating shaft of the motor 16 rotates into the mounting through hole and is fixed on the central stirring rod 13.

[0029] In the above embodiment, the return channel is a guide pipe fixedly installed on the top cover, and the upper end of the guide pipe is higher than the upper surface of the top cover. This is an optimized technical solution. In other embodiments, the guide pipe may not be provided, and the return channel may be directly opened on the top cover.

[0030] In the above embodiments, the first fastening device includes a limiting ring fixedly disposed on the pump pipe. The limiting ring has a limiting groove that mates with the upper end of the guide pipe. The limiting groove is tightly fitted with the upper end of the guide pipe. In other embodiments, the first fastening device may also be a pagoda connector.

[0031] In the above embodiments, the upper end of the pump tube is not lower than the lower end of the guide tube, which is an optimized technical solution. In other embodiments, the upper end of the pump tube can also extend downward through the lower end of the guide tube, but the upper end of the pump tube should not interfere with the rotation of the stirring component.

[0032] In the above embodiments, the lower end of the guide tube extends into the interior of the mixing tank, and the guide tube does not interfere with the rotation of the mixing components. This is an optimized technical solution. In other embodiments, the lower end of the guide tube can also be flush with the inner top surface of the top cover.

[0033] In the above embodiments, the second fastening device is a spring clamp, which is an optimized technical solution. In other embodiments, the second fastening device can also be a cable tie.
