DETAILED DESCRIPTION

[0031] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0032] This embodiment introduces the specific structure of a polyurethane online continuous mixing and foaming device. Figure 1-Figure 5 As shown, it includes a tank body 1 and a processing assembly installed inside the tank body 1 for polyurethane mixing, the processing assembly includes a mounting plate 2 arranged on the top of the tank body 1, and a stirring shaft 3 is movably mounted on the bottom end of the mounting plate 2 through a bearing, and a servo motor 24 for driving the stirring shaft 3 to rotate is installed on the top of the mounting plate 2;

[0033] like Figures 2 to 7 As shown, the bottom end of the stirring shaft 3 extends to the inside of the tank body 1 and is installed with a plurality of spaced-apart sub-rings 4, a gathering ring 5 is provided between two adjacent sub-rings 4, and two spaced-apart connecting columns 6 are provided between two adjacent gathering rings 5; a main bevel gear 7 is sleeved on the outside of the top end of the stirring shaft 3, and slave bevel gears 8 are meshed at both ends of the main bevel gear 7, and linkage shafts 9 are installed on the sides of the two slave bevel gears 8 away from the main bevel gear 7, and pressure plates 10 are installed on the outside of the ends of the two linkage shafts 9 away from the slave bevel gears 8, and the two pressure plates 10 are distributed front and back, and a touch plate 11 is provided on the top of each pressure plate 10;

[0034] The output shaft of the servo motor 24 passes through the mounting plate 2 and is fixed to the top of the stirring shaft 3. The servo motor 24 can drive the split ring 4 and the stirring blade 21 on the stirring shaft 3 to rotate through the connection between the output shaft of the servo motor 24 and the stirring shaft 3, so as to facilitate the mixing of the materials.

[0035] like Figure 2 and Figure 3As shown, the two touch plates 11 are externally sleeved with a same movable ring 12, a plurality of telescopic rods 13 for connecting the mounting plate 2 are installed on the top of the movable ring 12, and a spring 14 is installed on the outside of the bottom end of the telescopic rod 13, and the bottom of both ends of the movable ring 12 are installed with a fixed column 15 extending to the inside of the tank body 1, and the bottom end of the fixed column 15 is fixed to the gathering ring 5 located at the top of the inner cavity of the tank body 1;

[0036] Among them, the staff transports the materials to the inside of the tank body 1 through the feed pipe 22 for processing, and then starts the servo motor 24 to drive the stirring shaft 3 to rotate. The stirring shaft 3 synchronously drives the sub-ring 4, multiple stirring blades 21 and the main bevel gear 7 to rotate. The sub-ring 4 can break up the materials transported to the tank body 1 during the rotation process. At the same time, the main bevel gear 7 drives the pressure plate 10 on the linkage shaft 9 to rotate with the help of the meshing slave bevel gear 8. When the pressure plate 10 rotates and contacts the touch plate 11, the fixed column 15 connected to the movable ring 12 can be lifted and moved upward, thereby driving multiple gathering rings 5 ​​connected by the connecting column 6 to move upward. When the pressure plate 10 rotates and separates from the touch plate 11, the movable ring 12 drives the fixed column 15 to move downward with the help of the rebound of the spring 14, thereby driving the gathering ring 5 to move downward and contact the top of the sub-ring 4;

[0037] At the same time, by means of the rotation of the sub-ring 4 and the up-and-down movement of the gathering ring 5, the materials flowing in the sub-ring 4 and the gathering ring 5 can be ground, so as to avoid the presence of particles in the materials and the inability to fully mix them. Moreover, by means of the staggered distribution of multiple sub-rings 4 and multiple gathering rings 5, the effects of dispersing and aggregating the materials can be achieved, and the mixing effect of the materials can be improved. At the same time, the circulation rate of the materials can also be effectively slowed down, so that the materials can be fully ground and mixed.

[0038] Secondly, in order to enhance the mixing uniformity of the materials and prevent the materials from adhering to the outside of the polyring 5 and the sub-ring 4, the kinetic energy of the materials needs to be increased, such as Figure 1 and 2 As shown, fixing seats 16 are installed on both sides of the bottom of the tank body 1, and a vibration motor 17 is installed on the side of the fixing seat 16 away from the tank body 1. The bottom of the two vibration motors 17 is provided with a same positioning plate 18, and the positioning plate 18 is sleeved on the outside of the bottom end of the tank body 1. A positioning seat 19 is provided at the bottom of the positioning plate 18, and damping spring shock absorbers 20 are installed at the four corners of the top of the positioning seat 19, and the top of the damping spring shock absorber 20 is fixed to the bottom of the positioning plate 18;

[0039] Furthermore, the damping spring shock absorber 20 between the positioning plate 18 and the positioning seat 19 supports the tank body 1, so that the tank body 1 swings to a certain extent, and then the vibration of the vibration motor 17 drives the material to swing up and down and collide by vibration, so as to break up the agglomerated particles in the material, achieve rapid and uniform dispersion, improve the mixing quality, and through the transmission of vibration, the material adhering to the separation ring 4 and the gathering ring 5 can also be shaken off to prevent the material from adhering and affecting the grinding effect of the material particles;

[0040] Furthermore, in order to improve the mixing effect of the materials, the materials need to be stirred and mixed, such as Figure 2 , 5 As shown in Figures 7 and 8, two groups of stirring members for enhancing the uniformity of mixing are provided at the bottom of the inner cavity of the tank body 1; each group of stirring members includes a plurality of stirring blades 21, and the plurality of stirring blades 21 are installed on one side of the bottom end of the stirring shaft 3. Through the connection between the plurality of stirring blades 21 and the stirring shaft 3, the stirring shaft 3 can drive the stirring blades 21 to stir and mix the materials in the tank body 1, thereby improving the mixing efficiency of the materials;

[0041] In some examples, in order to facilitate the transportation of materials and the removal of mixed materials, such as Figure 1 As shown, a feed pipe 22 is fixedly connected to the front side of the top of the tank body 1, and a discharge pipe 23 is fixedly connected to the bottom of the tank body 1. The material is transported to the inside of the tank body 1 for processing through the feed pipe 22, and the discharge pipe 23 is provided to discharge the processed and mixed material, thereby improving the convenience of feeding and taking materials for the staff;

[0042] like Figure 4 , 5 As shown in FIG. 7 , a linkage seat 25 is provided on the outside of the linkage shaft 9 through a bearing sleeve, and the top of the linkage seat 25 is fixed to the bottom of the mounting plate 2;

[0043] Among them, through the connection between the linkage seat 25 and the mounting plate 2, the linkage seat 25 can support the linkage shaft 9 movably connected by the bearing, so as to ensure the stability of the linkage shaft 9 during operation and prevent the linkage shaft 9 from shaking during operation;

[0044] At the same time, in order to ensure the stability of the stirring shaft 3, the mounting plate 2 needs to be supported, such as Figure 3 As shown, two spaced support columns 26 are provided inside the front and rear ends of the movable ring 12, and the top of the support column 26 is fixed to the bottom of the mounting plate 2. The support column 26 is connected to the tank body 1 and the mounting plate 2, so that the support column 26 can support and fix the mounting plate 2, thereby ensuring the stability of the stirring shaft 3 connected to the mounting plate 2, and then a limiting ring 27 is provided on the outside of the bottom end of the stirring shaft 3 through a bearing movable sleeve, and a plurality of spaced limiting columns 28 are installed on the outside of the limiting ring 27, and the end of the limiting column 28 away from the limiting ring 27 is fixed to the inner wall of the tank body 1, and the limiting ring 27 supports and fixes the bottom end of the stirring shaft 3 by means of a plurality of limiting columns 28, thereby preventing the stirring shaft 3 from being unbalanced and causing shaking, thereby ensuring the running stability of the stirring shaft 3;

[0045] Secondly, in order to facilitate the flow of materials, such as Figure 7As shown, the top outer cross-section and the bottom outer cross-section of the sub-ring 4 are both set to be inclined, and the top inner cross-section and the bottom inner cross-section of the gathering ring 5 are both set to be inclined. By setting the sub-ring 4 and the gathering ring 5 to be inclined, when the material contacts the sub-ring 4, the material will diffuse outward, and when the material contacts the gathering ring 5, the material will flow inward, thereby achieving the effect of breaking up and aggregating the material and achieving the effect of sufficient mixing.

[0046] Finally, it should be noted that: Obviously, the above embodiments are only examples for the purpose of clearly explaining the present invention, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present invention.
