[0027] Example:

[0028] See also Figure 1 and Figure 2A stirring and mixing device for high-viscosity hot melt adhesive comprises a stirring barrel 1 and a bracket 2.

[0029] Specifically, if the high-viscosity hot melt adhesive is discharged through a traditional pipe after being stirred and mixed, the discharge speed will be slow, and it will be inconvenient to clean the pipe later, affecting the subsequent production quality of the high-viscosity hot melt adhesive. Therefore, in order to improve the discharge efficiency of the high-viscosity hot melt adhesive after stirring and mixing, the bracket 2 plays the main role of supporting the stirring barrel 1. After adding materials to the inside of the stirring barrel 1, the port of the stirring barrel 1 is sealed by the top cover 3, and the stirring mechanism 4 stirs and mixes the raw materials of the high-viscosity hot melt adhesive inside the stirring barrel 1 to form them. After forming, the top cover 3 is removed, and the stirring barrel 1 is driven by the driving mechanism 5. The stirring barrel 1 is rotated more than ninety degrees along the inside of the bracket 2 through the connecting rod 101, so that the port of the stirring barrel 1 is discharged downward, and the discharge efficiency is further improved with the assistance of the pushing mechanism 6. Therefore, the discharge method of the stirring and mixing device for high-viscosity hot melt adhesive is simple and efficient, and it is also conducive to cleaning the inside of the stirring barrel 1.

[0030] See also Figure 1 and Figure 2 The driving mechanism 5 includes a mounting plate 501 fixedly connected to the outer wall of the bracket 2, a second motor 502 is fixedly installed below the mounting plate 501, an output end of the second motor 502 extends to the inner side of the mounting plate 501 and is fixedly connected to a driving gear 503, one side of the driving gear 503 is meshedly connected to a driven gear 504, and the driven gear 504 is coaxially fixedly connected to a connecting rod 101 on one side.

[0031] Specifically, the driving mechanism 5 is fixedly mounted on the outer wall of the bracket 2 through the mounting plate 501, and the second motor 502 is activated to drive the coaxial driving gear 503 to rotate. When the driving gear 503 rotates, it drives the meshing driven gear 504 to rotate synchronously. The rotation of the driven gear 504 drives the coaxial connecting rod 101 to rotate, thereby realizing the rotation of the mixing barrel 1.

Arc grooves 201 are opened on both sides of the bracket 2, and the limiting rods 102 are respectively arranged in the corresponding arc grooves 201, and the limiting blocks 103 are arranged on the outer wall of the bracket 2.

[0033] Specifically, the stability of the mixing barrel 1 is increased by the cooperation of the limit rod 102, the limit block 103 and the arc groove 201, and the arc groove 201 can limit the rotation and reset position of the mixing barrel 1. When the driving mechanism 5 drives the mixing barrel 1 to rotate, the limit rod 102 slides along the arc groove 201 to ensure the rotation trajectory and stability of the mixing barrel 1.

[0034] See also Figure 5 The stirring mechanism 4 includes a first motor 401 fixedly installed above the top cover 3, the output end of the first motor 401 extends to the bottom of the top cover 3 and is fixedly connected to a stirring shaft 402, a plurality of stirrers 403 are fixedly connected to the outer wall of the stirring shaft 402 at equal intervals around the circumference, a scraper 404 is fixedly connected to the outer side of the stirrer 403, the stirring shaft 402, the stirrer 403 and the scraper 404 are all arranged inside the stirring barrel 1, and the scraper 404 is arranged in contact with the inner wall of the stirring barrel 1.

[0035] Specifically, when the top cover 3 and the mixing barrel 1 are closed, the stirring shaft 402, the agitator 403 and the scraper 404 are all located inside the mixing barrel 1, and the stirring shaft 402 can be driven to rotate by the first motor 401. The stirring shaft 402 can drive the agitator 403 to stir and mix the raw materials of the hot melt adhesive inside the mixing barrel 1, and the stirring shaft 402 drives the scraper 404 to scrape off the raw materials remaining on the inner wall of the mixing barrel 1 to ensure the purity of the hot melt adhesive. In addition, the structure of the top cover 3 and the stirring mechanism 4 is simple and compact, which is convenient for disassembly and assembly between the top cover 3 and the mixing barrel 1.

[0037] Specifically, the stirring mechanism 4 stirs and mixes the hot melt adhesive raw materials while the heating wire 105 heats the inside of the stirring barrel 1 to prevent the hot melt adhesive from solidifying during the stirring and mixing process and affecting the mixing of the raw materials. The insulation layer 104 can be made of materials such as glass wool to minimize heat loss.

[0038] See also Figure 2 and Figure 3The pushing mechanism 6 includes a cylinder 601 fixedly installed under the mixing barrel 1, and the output end of the cylinder 601 is fixedly connected to a push rod 602. The other end of the push rod 602 extends to the interior of the mixing barrel 1 and is fixedly connected to a pushing plate 603. A sealing ring 604 is fixedly sleeved on the outer wall of the pushing plate 603.

The push plate 603 can automatically push the high-viscosity hot melt adhesive inside the mixing barrel 1, thereby further improving the discharge efficiency of the hot melt adhesive. The sealing ring 604 can ensure that there is no gap between the push plate 603 and the inner wall of the mixing barrel 1, and the hot melt adhesive on the inner wall of the mixing barrel 1 can be removed while pushing the material.

Through the cooperation of the limit rod 102 and the arc groove 201, the mixing barrel 1 can rotate at an angle greater than ninety degrees, and the port is downward for discharging. The cylinder 601 is activated to drive the push rod 602 to push the push plate 603. The push plate 603 can automatically push the high-viscosity hot melt adhesive inside the mixing barrel 1, further improving the discharge efficiency of the hot melt adhesive.
