Detailed implementation mode
[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0024] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.
[0025] Please refer to Figures 1 to 5 , a mixing device for preparing curing agent provided by an embodiment of the present utility model, the mixing device for preparing curing agent includes a mixing tank 1, a mixing assembly 2, an auxiliary mixing assembly 3 and a dynamic mixing part 4.
[0026] In an embodiment of the present utility model, please refer to Figures 1 to 5 , a mixing assembly 2 and an auxiliary mixing assembly 3 for mixing the curing agent material are installed in the mixing tank 1. The mixing assembly 2 includes a mixing rod 21. A reciprocating thread section 22 is arranged on the middle rod section of the mixing rod 21, and a mixing blade 24 is fixedly installed at the bottom of the mixing rod 21. The auxiliary mixing assembly 3 includes a middle cavity gear 31. The middle cavity gear 31 is rotatably installed in the cavity opened at the top of the mixing tank 1, and two symmetrically distributed inclined middle connecting rods 32 are fixedly installed on the lower wheel surface of the middle cavity gear 31. A side mixing rod 33 is fixedly installed on each inclined middle connecting rod 32; the mixing rod 21 passes through the through cavity opened in the middle cavity gear 31 and is rotatably connected to the through cavity;
[0027] A servo motor 5 is fixedly installed on the mixing tank 1 through a frame, and a main shaft 51 is fixedly installed at the output end of the servo motor 5. The connection end of the main shaft 51 and the mixing rod 21 is fixedly connected, and a middle connecting part 6 for driving the middle cavity gear 31 and the mixing rod 21 to rotate in opposite directions is arranged on the main shaft 51.
[0028] It should be noted that after the raw materials for preparing the curing agent are put into the stirring tank 1, the servo motor 5 is started to drive the main shaft 51 to rotate. Since the connecting end of the main shaft 51 is fixedly connected to the stirring rod 21, the stirring blades 24 on the stirring rod 21 can quickly stir the materials. Since a connecting member 6 for driving the middle cavity gear 31 to rotate in the opposite direction to the stirring rod 21 is arranged on the main shaft 51, the middle cavity gear 31 drives the side stirring rod 33 to perform reverse rotation stirring through the inclined connecting rod 32.
[0029] This solution forms a double-stirring structure with a synergistic effect through the stirring assembly 2 (main stirring) and the auxiliary stirring assembly 3 (reverse stirring), forming a convective shear force, breaking the limitation of single-direction stirring, and significantly improving the mixing uniformity of the materials.
[0030] Furthermore, inclined blades 23 are fixedly installed on the stirring rods 21 at the upper and lower ends of the reciprocating thread section 22, further improving the stirring uniformity of the curing agent.
[0031] In the embodiment of the present utility model, please refer to Figures 1 to 5 , and the connecting member 6 includes a driving gear 61 and a rotating shaft 62. The driving gear 61 is fixedly sleeved on the main shaft 51. The rotating shaft 62 is rotatably installed on the upper surface of the stirring tank 1, and a linkage gear 63 and a driving gear 64 are fixedly installed on the rotating shaft 62 and distributed up and down. The linkage gear 63 is meshed and connected with the driving gear 61 through an annular toothed belt 65, and the driving gear 64 is meshed and connected with the middle cavity gear 31.
[0032] It should be noted that since the driving gear 61 is fixedly sleeved on the main shaft 51 and the linkage gear 63 is meshed and connected with the driving gear 61 through the annular toothed belt 65, the linkage gear 63 rotates in the same direction as the main shaft 51. Also, since the linkage gear 63 and the driving gear 64 are fixedly installed on the rotating shaft 62 and the driving gear 64 is meshed and connected with the middle cavity gear 31, the driving gear 64 drives the middle cavity gear 31 to rotate in the opposite direction to the main shaft 51.
[0033] In the embodiment of the present utility model, please refer to Figures 1 to 5 , and a dynamic stirring member 4 is arranged between the stirring assembly 2 and the auxiliary stirring assembly 3. The dynamic stirring member 4 includes a threaded cylinder 41. The threaded cylinder 41 is sleeved on the reciprocating thread section 22 and is threadedly connected with the reciprocating thread section 22. Both sides of the threaded cylinder 41 are fixedly installed with docking rods 42. Turbine blades 43 are fixedly installed on the opposite end faces of the two docking rods 42, and a sleeve 44 is fixedly installed on the turbine blades 43. The sleeve 44 is sleeved on the adjacent side stirring rods 33 and is slidably connected with the side stirring rods 33.
[0034] It should be noted that: Since the turbine blades 43 on both sides of the threaded cylinder 41 are sleeved on the side stirring rod 33 through the sleeve 44 to restrict the threaded cylinder 41, it is avoided that the threaded cylinder 41 deflects along with the reciprocating thread section 22 as the stirring rod 21 rotates. Therefore, when the stirring rod 21 rotates, the threaded cylinder 41 can slide up and down reciprocally along the reciprocating thread section 22. Since the side stirring rod 33 rotates in the opposite direction to the stirring rod 21, the turbine blades 43 in the dynamic stirring member 4 can rotate around the stirring rod 21 and lift and lower along the reciprocating thread section 22, thereby realizing high-speed shear breaking and ensuring the dispersion of large-particle materials.
[0035] Among them, in this application, the servo motor 5 adopts ECMA-C20604RS.
[0036] The working principle of the stirring device for preparing curing agent provided by the present utility model is as follows:
[0037] After putting the raw materials for preparing the curing agent into the stirring tank 1, the servo motor 5 is started to drive the main shaft 51 to rotate. Since the connection end of the main shaft 51 and the stirring rod 21 is fixedly connected, the stirring blades 24 on the stirring rod 21 can quickly stir the materials. Since there is a middle connection member 6 on the main shaft 51 for driving the middle cavity gear 31 to rotate in the opposite direction to the stirring rod 21. Specifically, since the driving gear 61 is fixedly sleeved on the main shaft 51, and the linkage gear 63 is meshed with the driving gear 61 through the annular tooth belt 65, the linkage gear 63 rotates in the same direction as the main shaft 51. Also, since the linkage gear 63 and the driving gear 64 are fixedly installed on the rotating shaft 62, and the driving gear 64 is meshed with the middle cavity gear 31, because the driving gear 64 drives the middle cavity gear 31 to rotate and rotates in the opposite direction to the main shaft 51, the middle cavity gear 31 drives the side stirring rod 33 to perform reverse rotation stirring through the inclined middle connection rod 32. This solution forms a double-stirring structure with a synergistic effect through the stirring assembly 2 (main stirring) and the auxiliary stirring assembly 3 (reverse stirring), forming a convective shear force, breaking the limitation of single-direction stirring, and significantly improving the mixing uniformity of the materials. Since the turbine blades 43 on both sides of the threaded cylinder 41 are sleeved on the side stirring rod 33 through the sleeve 44 to restrict the threaded cylinder 41, it is avoided that the threaded cylinder 41 deflects along with the reciprocating thread section 22 as the stirring rod 21 rotates. Therefore, when the stirring rod 21 rotates, the threaded cylinder 41 can slide up and down reciprocally along the reciprocating thread section 22. Since the side stirring rod 33 rotates in the opposite direction to the stirring rod 21, the turbine blades 43 in the dynamic stirring member 4 can rotate around the stirring rod 21 and lift and lower along the reciprocating thread section 22, thereby realizing high-speed shear breaking and ensuring the dispersion of large-particle materials.
