Description

Technical Field

[0001] The utility model belongs to the technical field of mixers. Specifically, it particularly relates to a high-fluidity AB two-component liquid glue dynamic mixer with good glue fluidity, not easy to be blocked, no need to be frequently cleaned, strong production continuity, good sealing performance, fast mixing speed and sufficient mixing. Background Art

[0002] The AB two-component liquid glue dynamic mixer is a device for quickly and evenly mixing two kinds of glues, such as mixing various two-component adhesives and fillers, and is widely used in industries such as electronic production, electrical products, civil construction, automobile manufacturing, gift decoration, etc.

[0003] If the fluidity of the two-component glue is relatively poor during mixing, it is very easy to cause the blockage of the mixer and requires frequent disassembly and cleaning. To facilitate disassembly and cleaning, the Chinese patent document with the authorization announcement number CN208275318U discloses a split-type double AB glue mixer. The technical solution of this patent document mainly includes: a mixing tube, a mixing head is connected to the end of the top of the mixing tube through a mixing tube mounting nut. An A glue cylinder body and a B glue cylinder body are respectively arranged on the left and right sides of the mixing head. The tops of the A glue cylinder body and the B glue cylinder body are respectively fixed on the left and right sides of the mixing valve mounting plate. A motor coupling is arranged on the mixing valve mounting plate, a mixing motor is arranged on the motor coupling, a stirring blade is arranged at the bottom of the mixing motor through shaft connection, and the mixing motor drives the stirring blade located at the bottom of the mixing tube to rotate and mix the A glue and the B glue respectively entering the mixing head from the A glue cylinder body and the B glue cylinder body and respectively discharged from the A glue outlet and the B glue outlet which are separately arranged at the bottom of the mixing tube to form AB glue. An A glue cylinder cover is arranged at the left end of the A glue cylinder body, an A glue valve rod penetrates through the A glue cylinder cover and enters the inside of the A glue cylinder body, an A glue adjusting nut is arranged on the A glue valve rod, a B glue cylinder cover is arranged at the right end of the B glue cylinder body, a B glue valve rod penetrates through the B glue cylinder cover and enters the inside of the B glue cylinder body, a B glue adjusting nut is arranged on the B glue valve rod, and an A glue inlet and a B glue inlet are respectively arranged on the A glue cylinder body and the B glue cylinder body.

[0004] It can be seen from this that the mixer is easy to be blocked and requires frequent disassembly and cleaning. In order to facilitate cleaning, the structure has to be improved. However, cleaning not only has a large labor intensity, but also has a great impact on the continuity of production. If only the fluidity of the glue is increased by heating, there will be a phenomenon that the glue with better fluidity leaks out due to the relatively poor sealing performance of the traditional mixer.

[0030] Embodiment 1

[0031] As Figures 1 to 6As shown in the figure, a high-fluidity AB two-component liquid glue dynamic mixer includes a dispensing valve A1 and a dispensing valve B2 whose discharge ports 11 are hermetically connected to a mixing seat 3. Two glue channels 31 are formed in the mixing seat 3. The two glue channels 31 are respectively connected to the two discharge ports 11. The glue in the two glue channels 31 is mixed in a mixing tube 4. A mixing paddle 41 connected to a stirring hook 42 is arranged in the mixing tube 4. The stirring hook 42 is driven to rotate by a driving motor 5. A heating rod 32 is embedded in the mixing seat 3. An outlet seat 7 is installed between the mixing seat 3 and the mixing tube 4. Two connecting channels 71 are formed in the outlet seat 7. The two connecting channels 71 respectively guide the glue in the two glue channels 31 to flow into the mixing tube 4. The stirring hook 42 penetrates through the mixing seat 3 and the outlet seat 7.

[0032] A first sealing assembly 6 is arranged between the stirring hook 42 and the mixing seat 3. The first sealing assembly 6 includes a seal 61, an upper pressing plate 63 located above the seal 61, and a lower pressing plate 64 located below the seal 61. A first bushing 62 in clearance fit with the stirring hook 42 is embedded in a first central through hole of the seal 61. First small bearings 65 embedded in the first central through hole and in bearing connection with the stirring hook 42 are respectively arranged at the upper and lower ends of the first bushing 62. An upper pressing plate sealing ring 631 is arranged between the lower end face of the upper pressing plate 63 and the upper end face of the seal 61. A lower pressing plate sealing ring 641 is arranged between the upper end face of the lower pressing plate 64 and the lower end face of the seal 61. A gland 66 fixedly integrated with the mixing seat 3 is arranged above the upper pressing plate 63.

The double-sealing structure design provides good sealing performance for the mixer, and even when the fluidity of the glue is very good, there will be no glue leakage phenomenon.

[0034] The working principle of this embodiment is as follows: two-component AB glue enters from the dispensing valve A1 and the dispensing valve B2 respectively, and flows from the dispensing valve A1 and the dispensing valve B2 through the glue channel 31 of the mixing seat 3 to the connecting channel 71 of the dispensing seat 7. Under the action of the heating rod 32, the glue flows smoothly in the glue channel 31 and the connecting channel 71, with a short residence time and no risk of blockage. Due to the double sealing structure design of the first sealing component 6 and the second sealing component 8, the glue will not seep out through the gap. After the AB glue enters the mixing tube 4, the driving motor 5 drives the stirring hook 42 to drive the stirring paddle 41 to rotate to fully mix the AB glues. The glue in this embodiment has good fluidity, and the connecting channel 71 can be designed to be narrower, so that the two glues flowing into the mixing tube 4 can be mixed more fully.
