[0001] The invention relates to the technical field of foam production equipment, in particular to a rapid foaming equipment for foam production. Background Art

[0002] Foam products refer to products made from foam, which are mainly used in fire fighting and other industries. Foam fire extinguishing agents are made of foaming agents, solvents, stabilizers, antifreeze agents and water. Fire extinguishing agents can be applied to various types of medium-multiple foam generators and are widely used in fire prevention and fire fighting in underground tunnels, hangars, underground oil depots, garages, ships, coal mines and limited spaces. Foam can also be used to produce foam boards;

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] like Figures 1 to 3As shown, a rapid foaming device for foam production is provided, wherein a sealing cover 2 is detachably installed on the top of a foaming machine body 1, a discharge end pipe 7 is fixedly inserted on the side of the bottom end of the foaming machine body 1, and a discharge hose 8 is fixed on one end of the discharge end pipe 7, a motor mounting frame 4 is fixed to the bottom of the lower part of the foaming machine body 1, a foaming motor 3 is fixed to the inner side of the motor mounting frame 4, an output shaft end of the foaming motor 3 passes through the bottom of the foaming machine body 1 and extends to the inside of the foaming machine body 1, a stirring main shaft 9 is fixed to the output shaft end of the foaming motor 3, a rotating hole 11 is provided on the outer surface of the stirring main shaft 9, a positioning hole 12 is provided on the inner side of the rotating hole 11, and the axes of the rotating hole 11 and the positioning hole 12 coincide, a plurality of annular grooves 10 are provided on the inner side of the annular groove 10, a transmission sealing ring 13 is rotatably installed, a plurality of stirring paddles 5 are installed between the stirring main shaft 9 and the transmission sealing ring 13, and the plurality of stirring paddles 5 located on the inner side of the same transmission sealing ring 13 are distributed in a circular array around the axis of the stirring main shaft 9.

[0030] like Figure 2 , Figure 4 and Figure 5 As shown, the stirring paddle 5 includes a transmission shaft 505, one end of the transmission shaft 505 is rotatably inserted into the inner side of the positioning hole 12, a first stirring rod 501 is fixed to the outer side of the end of the transmission shaft 505 close to the stirring main shaft 9, one end of the first stirring rod 501 is rotatably inserted into the inner side of the rotating hole 11, and the other end of the transmission shaft 505 is rotatably sleeved with a second stirring rod 502, one end of the second stirring rod 502 passes through the transmission sealing ring 13 and is rotatably connected to the transmission sealing ring 13, and three first stirring blade rods 503 are distributed in a circular array on the outer surface of the first stirring rod 501, and a plurality of first auxiliary stirring blades 506 parallel to each other are fixed to one side of the first stirring blade rod 503, and a plurality of first auxiliary stirring blades 506 parallel to each other are fixed to one side of the second stirring blade rod 503. Three second stirring blade rods 504 are distributed in a circular array on the outer surface of the stirring rod 502, and a plurality of second auxiliary stirring blades 507 parallel to each other are fixed on one side of the second stirring blade rod 504. The stirring main shaft 9 is driven to rotate by the foaming motor 3, so that the stirring main shaft 9 drives the first stirring rod 501, the second stirring rod 502, and the transmission shaft 505 to make circular motion around the axis of the stirring main shaft 9, and the first stirring blade rod 503 and the first auxiliary stirring blade 506 on the outer side of the first stirring rod 501 and the second stirring blade rod 504 and the second auxiliary stirring blade 507 on the outer side of the second stirring rod 502 are used to stir and mix the foam raw materials located inside the foaming machine body 1.

[0031] The first auxiliary stirring blades 506 and the second auxiliary stirring blades 507 are staggered up and down, the thickness of the first auxiliary stirring blades 506 and the second auxiliary stirring blades 507 are the same, and the spacing between two adjacent first auxiliary stirring blades 506 and the second auxiliary stirring blades 507 is larger than the thickness of the first auxiliary stirring blades 506 and the second auxiliary stirring blades 507, to ensure that the rotating first auxiliary stirring blades 506 and the second auxiliary stirring blades 507 do not collide with each other, and utilize the shear force generated when the first auxiliary stirring blades 506 and the second auxiliary stirring blades 507 pass by each other, so as to better promote uniform mixing of the raw materials.

[0032] like Figure 2 , Figure 4 , Figures 6 to 8 As shown, a transmission assembly 6 is installed between the transmission sealing ring 13 and the inner wall of the annular groove 10, and the transmission assembly 6 includes a fixed ring 601, and the fixed ring 601 is fixed to the inner wall of the annular groove 10. A plurality of meshing teeth 608 are distributed in a circular array on the upper surface of the fixed ring 601. A driving gear 602 is installed above the fixed ring 601, and the driving gear 602 is meshed with the fixed ring 601 through the meshing teeth 608. The driving gear 602 is fixed to the outer side of one end of the transmission shaft 505 to ensure that when the stirring main shaft 9 drives the transmission shaft 505 to make a circular motion around the axis of the stirring main shaft 9, when the transmission shaft 505 drives the driving gear 602 to move along the surface of the fixed ring 601, the driving gear 602 rolls on the surface of the fixed ring 601 through meshing with the meshing teeth 608 and drives the transmission shaft 505 to rotate.

[0033] A transmission gear 603 is meshedly connected to the top of the driving gear 602, and a transmission gear ring 606 is meshedly connected to the outer side of the transmission gear 603. The axis of the transmission gear ring 606 coincides with the axis of the driving gear 602. Two rotating connecting blocks 607 are fixed to the end of the transmission gear ring 606 facing the second stirring rod 502. The rotating connecting block 607 is bent in an L shape and one end of the rotating connecting block 607 is fixed to the outer side of one end of the second stirring rod 502. When the driving gear 602 drives the transmission shaft 505 to rotate, the transmission gear ring 606 is driven to rotate at the same time through the transmission gear 603, so that the second stirring rod 502 and the transmission shaft 505 rotate at the same time, and the second stirring rod 502 rotates in opposite directions to the transmission shaft 505, so that the first auxiliary stirring blade 506 and the second auxiliary stirring blade 507 make circular motions in opposite directions, so as to better stir and mix the foam raw materials.

[0034] A supporting short shaft 604 is fixedly passed through the interior of the transmission gear 603, and a hanging block 605 is installed on the outer side of the supporting short shaft 604. The top of the hanging block 605 is fixed to the transmission sealing ring 13, and the supporting short shaft 604 is rotatably connected to the hanging block 605. The hanging block 605 and the supporting short shaft 604 are used to fix the position of the transmission gear 603 to ensure that when the transmission gear 603 rotates around the axis of the stirring main shaft 9 as the transmission sealing ring 13 rotates, the rotation of the driving gear 602 is transmitted and the transmission gear ring 606 rotates.

[0035] The width of the driving gear 602 is twice that of the transmission gear 603 and the transmission gear ring 606, and the transmission gear ring 606 does not contact the fixed ring 601 when viewed from a top view, ensuring that when the driving gear 602 rolls against the surface of the fixed ring 601, it can smoothly drive the transmission gear 603 and the transmission gear ring 606 to rotate, and the rotating transmission gear ring 606 will not contact or collide with the fixed ring 601.

[0036] Working principle: first, the raw materials for foam production are added into the foaming machine body 1, then the sealing cover 2 is closed and the power of the foaming machine is turned on and started, the foaming motor 3 is powered on and started and drives the stirring main shaft 9 to rotate, at this time, the stirring main shaft 9 drives the transmission shaft 505 to make a circular motion around the axis of the stirring main shaft 9, at this time, the transmission shaft 505 drives the first stirring rod 501 and the second stirring rod 502 to rotate at the same time, so that the first stirring blade rod 503, the first auxiliary stirring blade 506 outside the first stirring rod 501 and the second stirring blade rod 504, the second auxiliary stirring blade 507 outside the second stirring rod 502 simultaneously make a circular motion around the axis of the stirring main shaft 9, and the first stirring rod 501, the second stirring rod 502, the first auxiliary stirring blade 506, and the second auxiliary stirring blade 507 are used to stir and mix the raw materials inside the foaming machine body 1;

[0037] While the transmission shaft 505 performs circular motion around the axis of the stirring main shaft 9, the driving gear 602 fixed on the outer side of the end of the transmission shaft 505 penetrating the transmission sealing ring 13 will move on the surface of the fixed ring 601. Since the driving gear 602 is meshed with the fixed ring 601 through the meshing teeth 608, the driving gear 602 rolls on the surface of the fixed ring 601 as the end of the transmission shaft 505 moves. At this time, the driving gear 602 drives the transmission shaft 505, the first stirring rod 501, and the first stirring blade rod 503 and the first auxiliary stirring blade 506 outside the first stirring rod 501 to perform circular motion around the axis of the transmission shaft 505.

[0038] At the same time, the active gear 602 rolls and drives the transmission gear 603 meshing with it to rotate. When the transmission gear 603 rotates, it drives the transmission gear ring 606 meshing with the transmission gear 603 to rotate. At this time, the transmission gear ring 606 rotates the second stirring rod 502 through the rotating connecting block 607 fixed to the end of the second stirring rod 502. Since the active gear 602 and the transmission gear ring 606 are transmitted through the transmission gear 603, the transmission gear ring 606 drives the rotating connecting block 607 and the second stirring rod 502 to rotate with the transmission shaft 505. The circular motion in opposite directions makes the first auxiliary stirring blade 506 and the second auxiliary stirring blade 507 rotate in opposite directions around the axis of the transmission shaft 505. When the first auxiliary stirring blade 506 and the second auxiliary stirring blade 507 rotating in different directions make circular motion around the axis of the stirring main shaft 9, the raw materials inside the foaming machine body 1 make irregular flow, which accelerates the mixing of the raw materials, makes the raw materials mixed more evenly and fully, improves the stirring rate of the raw materials, shortens the stirring time, improves the foaming efficiency of the foam, and makes the foamed raw materials more delicate.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
