Description
Technical Field
[0001] The invention relates to the technical field of foaming machines, in particular to a foaming machine and a method for producing fireproof insulation boards. Background Art
[0002] The foaming machine commonly used in the production of fireproof insulation boards is a professional equipment that converts liquid raw materials into foam. This foaming machine mixes the raw liquid required for fireproof insulation boards with gas through specific processes such as heating, mixing, and compression, and uses the pressure of the gas to expand it into a foam state. The foaming machine plays a key role in the production of fireproof insulation boards because it directly affects the quality and performance of the product.
[0003] The foaming machine for producing insulation boards mainly uses polyurethane to fill the inside of the insulation board. Since the thermal conductivity of the polyurethane core material is low, it can effectively prevent the transfer of heat, thereby improving the thermal insulation effect of the insulation board. At the same time, it can also ensure the temperature stability inside the insulation board, reduce energy loss and have a good thermal insulation effect. Polyurethane also has high compressive strength and can be used for a long time under extremely high temperatures. In summary, polyurethane can not only improve the performance of thermal insulation, but also enhance the compressive strength and safety of use. It is one of the preferred filling materials for insulation boards.
[0004] During the filling of the interior of the insulation board by a conventional polyurethane foaming machine, in most of the production processes, the polyurethane will not begin to expand until it completely enters the insulation board. When producing composite insulation boards or insulation boards with a larger internal space, a large amount of polyurethane is required for filling. During the filling period, since the polyurethane will not enter the foaming and expansion state until it enters, when producing new types of insulation boards, excessive use of polyurethane may lead to overflow of the expanded polyurethane during the later foaming and expansion. Therefore, a foaming machine is needed that can save polyurethane materials while not affecting the polyurethane insulation. Summary of the invention

[0010] Preferably, a feed pipe is fixedly installed on the inner side of the mixing bin, and the interiors of bins A and B are connected to the interior of the mixing bin through the feed pipe.
[0011] Preferably, a support frame is fixedly mounted on the inner wall of the mixing bin, an outer surface of the support frame is rotatably connected to a non-powered shaft, and two groups of turbine blades are fixedly mounted on the outer surface of the non-powered shaft, and the installation directions of the two groups of turbine blades are opposite to each other.
[0012] Preferably, a convergence plate is fixedly mounted on the inner wall of the mixing bin below the support frame, a one-way valve is fixedly mounted on the inner wall of the convergence plate, and a cross diversion groove is fixedly mounted on the bottom surface of the convergence plate.
[0013] Preferably, a feed pipe and an air pressure pipe are fixedly installed on the inner side of the shell, the outer surfaces of the feed pipe and the air pressure pipe are fixedly installed on the inner side of the melt bin, and the output heights of the feed pipe and the air pressure pipe are higher than the threaded leaves.
[0014] Preferably, a mounting frame is fixedly mounted on the outer surface of the mixing bin, and two solenoid valves are fixedly mounted on the inner surface of the mounting frame, and the output end and the input end of the solenoid valve are both connected to the feed pipe.
[0015] Preferably, an L-shaped plate is installed on the outer surface of the shell, and a display and a console are fixedly installed on the outer surface of the L-shaped plate by screws. Two control rods are installed on both sides of the shell, and the two control rods respectively control the solenoid valves located under the A bin and the B bin.
[0016] Production method of fireproof insulation board:
[0017] S1: First, transport the "white material" and "black material" into bin A and bin B respectively. The default position of the piston plate of the hydraulic rod before starting is close to the turbine blade. Before use, input the PP material into the melt bin through the feed pipe and start preheating the heating plate.
[0018] S2: After the preparation work is completed, start the active motor and the hydraulic rod. The hydraulic rod pulls the piston plate upward. When a sufficiently large negative pressure is generated under the piston plate, the solenoid valve is closed at the same time by manipulating the control rod. After the solenoid valve is closed, the negative pressure generated under the piston plate can suck the "white material" and "black material" in bins A and B into the mixing bin.
[0019] S3: When it is officially used, the hydraulic rod drives the piston plate to press down, and the piston plate pushes the "white material" and "black material" inside the mixing chamber into the bottom of the mixing chamber. At this time, the active motor runs, driving the rotating rod and the threaded blade to rotate, which can guide the PP material to approach and contact the heating plate, so that the PP material melts, and the gas is transported into the melting chamber through the air pressure pipe to increase the air pressure, so that the melted PP material is sprayed out through the nozzle to form linear fibers and contact the inner wall of the polyurethane. After the polyurethane is produced, it enters the final stage of foaming. The PP fibers sprayed on its inner wall can increase the strength of the polyurethane after solidification, which is used to reduce the collapse of the cylindrical polyurethane. Then the produced cylindrical polyurethane can be laid flat on the inner wall of the insulation board and stacked layer by layer.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. The present application cooperates with a mixing bin, a melting bin, a spray plate, a mixing disc, a circular port, an output channel, an active motor, a rotating rod, a threaded blade, a heating plate, a mixing plate and a spray head. The material entering the mixing bin can enter the mixing disc through the output channel and be discharged through the circular port below the mixing disc. When the material reaches the position from the output channel to the mixing disc, the mixture of "material A" and "material B" begins to expand. Due to the shape of the circular port, the expanded polyurethane expansion body will present a circular tube shape when discharged. The active motor can drive the rotating rod to rotate. The rotating rod rotates. When the screw blade rotates, it can drive the screw blade and the mixing plate to rotate, and the granular or powdered polypropylene (PP) is put into the screw blade. The polypropylene (PP) can reach the position between the heating plate and the mixing plate along the rotation of the screw blade. There are empty grooves between the heating plate and the mixing plate. The spacing between the empty grooves is small, so that the polypropylene (PP) particles will not directly pass through the heating plate and the mixing plate, but will stay between the heating plate and the mixing plate and roll repeatedly. Therefore, the granular or powdered polypropylene (PP) will be heated to liquid state at the position between the heating plate and the mixing plate, and through the heating The empty slot between the plate and the mixing plate flows to the spray plate below. At the same time, adding air into the melt chamber can increase the air pressure in the melt chamber, so that the liquid polypropylene (PP) on the spray plate will be squeezed into the nozzle by the air pressure and sprayed outward. The sprayed liquid polypropylene (PP) will quickly solidify into linear fibers when it is cooled. The rotating rod can drive the nozzle to rotate synchronously when rotating, so the nozzle can rotate to spray liquid polypropylene (PP) and make the liquid polypropylene (PP) spirally sprayed on the inner wall of the hollow cylindrical polyurethane expansion body. The high-temperature liquid polypropylene (PP) and the added The high temperature generated by the hot plate can increase the foaming and solidification speed of polyurethane, thereby ensuring that the polyurethane near the nozzle can enter a state of expansion and solidification. The generated hollow cylindrical polyurethane directly enters the interior of the insulation board, and the solidified polypropylene (PP) fiber can support the inner wall of the hollow cylindrical polyurethane to reduce the collapse of the hollow cylindrical polyurethane when entering the insulation board. This allows the polyurethane to be filled into the insulation board while reducing the amount of polyurethane expansion overflow in the later stage, thereby solving the problem of excessive polyurethane filling that is prone to cause expansion overflow in the later stage.
[0022] 2. The present application realizes the cooperation between the solenoid valve and the control rod. The control rod controls the two solenoid valves through the controller. When only one control rod is pulled, the controller will determine it as a false touch. Only when both control rods are pulled, the two solenoid valves will be opened, so as to ensure that the amount of "white material" and "black material" released from the A bin and the B bin is the same while preventing false touch.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0033] Example: Figure 1-Figure 8As shown, the present invention provides a technical solution of a foaming machine and method for producing a fireproof insulation board, including a shell 1, a mixing bin 2 is arranged inside the shell 1, a hydraulic rod 3 is arranged above the mixing bin 2, A bin 4 and B bin 5 are arranged on the left and right sides of the mixing bin 2, a melt bin 6 is arranged below the mixing bin 2, a spray disc 7 is rotatably connected to the bottom end of the melt bin 6, a nozzle 8 is installed inside the spray disc 7, the shell 1 can provide a fixing effect on the internal components, and a handle is also installed on the outer surface of the shell 1 for easy use by personnel, the hydraulic rod 3 can generate a large negative pressure inside the mixing bin 2 when reversely driven, and the negative pressure can draw the materials in the A bin 4 and the B bin 5 into the mixing bin 2, the A bin 4 carries polyurethane white material, which is composed of combined polyols (combined polyethers or polyesters) and other additives such as foaming agents, commonly known as "white material" in the industry, and the B bin 5 carries polyurethane black material, the main component of which is isoester, commonly known as "black material" in the industry, and the "white material" and the "black material" are initially contacted and fused in the mixing bin 2.
[0034] Four output channels 32 are fixedly installed on the inner side of the mixing bin 2, a mixing disk 9 is fixedly installed on the bottom end of the output channel 32, and a circular opening 10 is fixedly installed on the outer surface of the mixing disk 9. The material entering the mixing bin 2 can enter the mixing disk 9 through the output channel 32 and be discharged through the circular opening 10 below the mixing disk 9. Because the "black material" and the "white material" have been initially contacted and mixed in the mixing bin 2, their chemical reaction has begun. Therefore, when the material reaches the position from the output channel 32 to the mixing disk 9, the mixture of "material A" and "material B" begins to expand. Due to the shape of the circular opening 10, the expanded polyurethane expansion body will present the shape of a circular tube when discharged.
[0035] The inside of the melt-plastic bin 6 is provided with an active motor 11, a rotating rod 12 is fixedly installed at the output end of the active motor 11, a threaded leaf 13 is fixedly installed on the outer surface of the rotating rod 12, the bottom end of the rotating rod 12 and the outer surface of the spray disc 7 are fixedly installed, a heating plate 14 is fixedly installed on the inner side of the melt-plastic bin 6, a mixing plate 15 is fixedly installed on the outer surface of the rotating rod 12, the heating plate 14 and the mixing plate 15 are arranged alternately, the active motor 11 can drive the rotating rod 12 to rotate, and the rotating rod 12 can drive the threaded leaf 13 and the mixing plate 15 to rotate when rotating, and the specific model of the heating plate 14 is the ly-450a graphite electric heating plate in the prior art , granular or powdered polypropylene (PP) is put above the threaded leaf 13, and the polypropylene (PP) can reach the position between the heating plate 14 and the mixing plate 15 along the rotation of the threaded leaf 13. There are empty slots between the heating plate 14 and the mixing plate 15, and the spacing between the empty slots is small, so that the polypropylene (PP) particles will not directly pass through the heating plate 14 and the mixing plate 15, but will stay between the heating plate 14 and the mixing plate 15 and roll repeatedly. The heating plate 14 can be heated to 230°C to 290°C, and the melting temperature of the polypropylene (PP) is between 220°C and 280°C, so the granular or powdered polypropylene (PP) The polypropylene (PP) will be heated to a liquid state at a position between the heating plate 14 and the mixing plate 15, and will flow to the spray plate 7 below through the empty groove between the heating plate 14 and the mixing plate 15. At the same time, the air is added into the melt chamber 6 to increase the air pressure in the melt chamber 6, so that the liquid polypropylene (PP) on the spray plate 7 will be squeezed into the nozzle 8 by the air pressure and sprayed outward. The sprayed liquid polypropylene (PP) will be cooled and quickly solidified to form linear fibers. The rotating rod 12 can drive the nozzle 8 to rotate synchronously when rotating, so the nozzle 8 can rotate to spray out the liquid polypropylene (PP), and make the liquid polypropylene (PP) spirally sprayed in the hollow cylindrical polypropylene. On the inner wall of the urethane expansion body, the high temperature liquid polypropylene (PP) and the high temperature generated by the heating plate 14 can increase the solidification speed of the polyurethane, thereby ensuring that the polyurethane near the nozzle 8 can enter a solidified state, and the generated hollow cylindrical polyurethane directly enters the interior of the insulation board. The solidified polypropylene (PP) fiber can support the inner wall of the hollow cylindrical polyurethane to reduce the collapse of the hollow cylindrical polyurethane when entering the insulation board, so that the polyurethane can be filled into the insulation board while reducing the amount of polyurethane expansion overflow in the later stage, thereby solving the problem of excessive polyurethane filling that is prone to cause expansion overflow in the later stage.
[0036] The inner wall of the outer shell 1 is fixedly mounted to the outer surface of the hydraulic rod 3 by bolts. A piston plate 16 is fixedly mounted on the output end of the hydraulic rod 3. The outer surface of the piston plate 16 is slidably connected to the inner wall of the mixing bin 2. The hydraulic rod 3 can push or pull back the piston plate 16 with the outer shell 1 as a fixed point, so that the piston plate 16 can move up and down on the inner wall of the mixing bin 2. When the piston plate 16 moves downward, it can push the material in the mixing bin 2 to flow downward, and when the piston plate 16 moves upward, it can generate negative pressure in the space below the piston plate 16.
[0037] A feed pipe 17 is fixedly installed on the inner side of the mixing bin 2. The interiors of bins A 4 and B 5 are interconnected with the interior of the mixing bin 2 through the feed pipe 17. The materials in bins A 4 and B 5 can be infused into the mixing bin 2 through the feed pipe 17. When the piston plate 16 moves upward to generate negative pressure, the materials in bins A 4 and B 5 can be sucked into the mixing bin 2 through the feed pipe 17. At the same time, a valve that can only flow in one direction is also installed inside the feed pipe 17 to prevent the material in the mixing bin 2 from flowing back into the feed pipe 17.
[0038] A support frame 18 is fixedly installed on the inner wall of the mixing bin 2, and a non-powered shaft 19 is rotatably connected to the outer surface of the support frame 18. Two groups of turbine blades 20 are fixedly installed on the outer surface of the non-powered shaft 19. The installation directions of the two groups of turbine blades 20 are opposite to each other. The support frame 18 can provide support for the non-powered shaft 19. When the piston plate 16 moves downward, it can push the material to flow downward and push the turbine blades 20 to rotate. Since the installation directions of the two groups of turbine blades 20 are opposite to each other, the rotation directions of the two groups of turbine blades 20 are also opposite. The turbine blades 20 rotating in opposite directions can mix the "white material" and the "black material" together to ensure that the downward flowing materials are completely mixed and start a chemical reaction.
[0039] A confluence plate 21 is fixedly installed on the inner wall of the mixing bin 2 below the support frame 18, a one-way valve 22 is fixedly installed on the inner wall of the confluence plate 21, and a cross diversion groove 23 is fixedly installed on the bottom surface of the confluence plate 21. The one-way valve 22 can ensure that the material passing through the confluence plate 21 will not flow back, and ensure that the piston plate 16 generates negative pressure when moving upward, and the cross diversion groove 23 can divide the material into four flow directions.
[0040] A feed pipe 24 and an air pressure pipe 25 are fixedly installed on the inner side of the outer shell 1. The outer surfaces of the feed pipe 24 and the air pressure pipe 25 are fixedly installed on the inner side of the melt bin 6. The output heights of the feed pipe 24 and the air pressure pipe 25 are both higher than the threaded leaves 13. Granular or powdered polypropylene (PP) can be transported into the melt bin 6 through the feed pipe 24. A camshaft driven by an electric motor is also installed on the outside of the feed pipe 24. The camshaft can generate vibration when rotating to reduce the blockage of the granular or powdered polypropylene (PP) in the feed pipe 24. The other end of the air pressure pipe 25 is connected to an air pump, which can increase the air pressure in the melt bin 6 to ensure that the liquid polypropylene (PP) in the melt bin 6 can be sprayed outward from the nozzle 8.
[0041] A mounting frame 26 is fixedly installed on the outer surface of the mixing bin 2, and two solenoid valves 27 are fixedly installed on the inner surface of the mounting frame 26. The output end and the input end of the solenoid valve 27 are both connected to the feed pipe 17. The mounting frame 26 can provide support for the solenoid valve 27, and the solenoid valve 27 can control the closure of the feed pipe 24 under the A bin 4 and the B bin 5.
[0042] An L-shaped plate 28 is installed on the outer surface of the shell 1, and a display 29 and a control console 30 are fixed on the outer surface of the L-shaped plate 28 by screws. Two control rods 31 are installed on both sides of the shell 1, and the two control rods 31 respectively control the solenoid valves 27 located below the A bin 4 and the B bin 5. The L-shaped plate 28 can fix the display 29 and the control console 30 on the outer surface of the shell 1. The control rod 31 controls the two solenoid valves 27 through a controller. When only one control rod 31 is pulled, the controller will determine it as a false touch. Only when two control rods 31 are pulled, the two solenoid valves 27 will be opened, so as to ensure that the amount of "white material" and "black material" released from the A bin 4 and the B bin 5 is the same while preventing false touch.
[0043] When the equipment is needed, first convey the "white material" and "black material" into bin A 4 and bin B 5 respectively. Before starting, the default position of the piston plate 16 of the hydraulic rod 3 is close to the turbine blade 20. Before use, input the PP material into the melt bin 6 through the feed pipe 24 and start preheating the heating plate 14. Start the active motor 11 and the hydraulic rod 3. The hydraulic rod 3 pulls the piston plate 16 to move upward. When a sufficiently large negative pressure is generated under the piston plate 16, the solenoid valve 27 is closed at the same time by manipulating the control rod 31. After the solenoid valve 27 is closed, the negative pressure generated under the piston plate 16 can suck the "white material" and "black material" in bin A 4 and bin B 5 into the mixing bin 2. The hydraulic rod 3 drives the piston plate 16 to press down. The piston plate 16 The "white material" and "black material" in the mixing bin 2 are pushed into the bottom of the mixing bin 2. At this time, the active motor 11 runs, driving the rotating rod 12 and the threaded blade 13 to rotate, which can guide the PP material to approach and contact the heating plate 14 to melt the PP material, and transport gas to the melting bin 6 through the air pressure pipe 25 to increase the air pressure, so that the melted PP material is sprayed out through the nozzle 8 to form linear fibers and contact the inner wall of the polyurethane. After production, the polyurethane enters the final stage of foaming. The PP fibers sprayed on its inner wall can increase the strength of the polyurethane after solidification, which is used to reduce the collapse of the cylindrical polyurethane. Then the produced cylindrical polyurethane can be spread on the inner wall of the insulation board and stacked layer by layer.

When a sufficiently large negative pressure is generated under the piston plate (16), the solenoid valve (27) is closed at the same time by operating the control rod (31). After the solenoid valve (27) is closed, the negative pressure generated under the piston plate (16) can suck the "white material" and "black material" in the A bin (4) and the B bin (5) into the mixing bin (2). S3: When in use, the hydraulic rod (3) drives the piston plate (16) to press down, and the piston plate (16) pushes the "white material" and "black material" in the mixing chamber (2) into the bottom of the mixing chamber (2). At this time, the active motor (11) runs, driving the rotating rod (12) and the threaded blade (13) to rotate, which can guide the PP material to approach and contact the heating plate (14), so that the PP material melts, and the gas is transported into the melting chamber (6) through the air pressure pipe (25) to increase the air pressure, so that the melted PP material is sprayed out through the nozzle (8) to form linear fibers and contact the inner wall of the polyurethane. After the polyurethane is produced, it enters the final stage of foaming. The PP fibers sprayed on its inner wall can increase the strength of the polyurethane after solidification, so as to reduce the collapse of the cylindrical polyurethane. Then, the produced cylindrical polyurethane can be spread on the inner wall of the insulation board and stacked layer by layer.
