Description

Technical Field

[0001] This utility model relates to the field of adhesive mixing, specifically to a two-component adhesive double-layer mixer. Background Technology

[0002] Currently, existing adhesive mixers mainly consist of a mixing cup, a mixing shaft, and a mixing impeller. When using a mixer to address the mixing problem of two-component adhesives, the two adhesives enter the mixing cup and fall onto the mixing impeller, where they are thrown out and mixed before flowing out through the outlet. However, in actual mixing processes, uneven mixing often occurs, which directly affects the adhesive's performance and fails to meet the requirements of scenarios demanding high-quality adhesive mixing. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a two-component adhesive double-layer mixer, the technical solution of which is as follows:

[0004] A two-component adhesive double-layer mixer includes a mixing drum and a mixing shaft. The mixing drum includes an upper mixing drum and a lower mixing drum aligned vertically. The upper and lower mixing drums are separate structures connected as one unit by quick-release clamps. A funnel-shaped baffle is fixed to the inner wall of the upper mixing drum. A mixing motor, a material A feed pipe, and a material B feed pipe are mounted on the upper mixing drum via a mounting plate. The output shaft of the mixing motor is connected to the mixing shaft via a coupling. The mixing shaft passes through the center of the upper mixing drum, the funnel-shaped baffle, and the lower mixing drum. An upper mixing plate and a lower mixing plate are fixed on the mixing shaft and separated vertically by the funnel-shaped baffle. The upper mixing plate is located inside the upper mixing drum, and the lower mixing plate is located inside the lower mixing drum. The lower ends of the material A feed pipe and the material B feed pipe are located above the upper mixing plate. A discharge port is provided at the bottom of the lower mixing drum.

[0005] Furthermore, the lower end of the upper stirring cylinder and the upper end of the lower stirring cylinder are provided with corresponding external convex rings; the quick-release clamp includes an A-shaped sleeve, a B-shaped sleeve, a hinge bolt, and a wing nut. Both the A-shaped sleeve and the B-shaped sleeve are provided with grooves that can wrap the external convex rings. One end of the A-shaped sleeve and one end of the B-shaped sleeve are hinged together. The other end of the A-shaped sleeve and the other end of the B-shaped sleeve are both provided with outwardly opening U-shaped parts. The U-shaped part of the A-shaped sleeve is hinged to the circular part of the hinge bolt. After the threaded part of the hinge bolt rotates into the U-shaped part of the B-shaped sleeve, it is tightened with the wing nut.

[0006] Furthermore, the edges of both the upper and lower mixing plates are provided with a number of spaced-apart upward-facing square mixing teeth.

[0007] Furthermore, the mounting plate has a downward fixing strip along its edge, which is fixed to the outer wall of the upper mixing cylinder by bolts.

[0008] Furthermore, the top of the funnel-shaped baffle is fixed to the inner wall of the upper stirring cylinder by welding.

[0009] Furthermore, the center of the upper stirring plate is welded to the stirring shaft.

[0010] Furthermore, the lower mixing plate is fixed to the mixing shaft by screws.

[0011] Compared with the prior art, the present invention mainly has the following beneficial technical effects:

[0012] 1. This utility model optimizes the stirring structure by setting up two stirring discs separated by a funnel-shaped partition, which mixes the two-component adhesive twice, achieving a more thorough mixing of the two adhesives. This effectively solves the problem of uneven mixing in existing stirrers, significantly improves the mixing quality of the adhesive, ensures the performance of the adhesive, and can fully meet the requirements of scenarios with high requirements for the mixing quality of adhesives.

[0013] 2. The double-layer mixer of this utility model adopts a split structure and is connected by quick-release clamps. This design facilitates the disassembly, cleaning and maintenance of the mixer.

[0014] 3. The upper mixing plate of this utility model is fixed by welding, which ensures that it will not loosen due to high-speed rotation during the mixing process, thus ensuring the stable operation of the equipment.

[0015] 4. The lower mixing plate of this utility model is fixed with screws, which makes it easy to replace and adjust according to actual needs, thus enhancing the flexibility and practicality of the equipment.

[0016] 5. This utility model has the characteristics of "three fasts"—fast feeding, fast mixing, and fast discharging—effectively preventing the passive situation of premature reaction caused by long contact time between the two-component liquids. Attached Figure Description

[0028] To enable those skilled in the art to better understand this utility model, its basic workflow is briefly described below:

[0029] Once ready, start the stirring motor 3. The liquid two-component adhesive, namely material A and material B, is pumped into material A feed pipe 4 and material B feed pipe 5 respectively, and then falls onto the upper stirring plate 11 inside the upper stirring drum 1. The upper stirring plate 11 rotates with the stirring shaft 13. As the upper stirring plate 11 rotates, materials A and B are thrown out from the gaps between adjacent stirring teeth 10, and after hitting the inner wall of the upper stirring drum 1, they mix and flow downstream. They then flow into the lower stirring plate 9 through the central hole of the funnel-shaped baffle 12. As the lower stirring plate 9 rotates, materials A and B are thrown out from the gaps between adjacent stirring teeth 10, and after hitting the inner wall of the lower stirring drum 8, they mix again and flow downstream. After two mixing processes, materials A and B are fully mixed to become a qualified two-component adhesive. Finally, the two-component adhesive flows out from the discharge port 7 and enters the subsequent process.
