Description

Technical Field

[0001] This invention belongs to the field of sound-insulating polyurethane foam production technology, specifically referring to a sound-insulating polyurethane foam production equipment and its usage method. Background Technology

[0002] The polyurethane composite material used in sound-insulating foam is a high-performance and environmentally friendly material. It is made by mixing polyurethane foam with various additives through a special process. This material not only has excellent sound insulation properties, effectively blocking sound transmission, but also has the advantage of being lightweight, durable, and able to maintain stable performance over a long period of time.

[0003] The existing sound-insulating polyurethane foam production equipment has the following problems:

[0004] 1. In the production of sound-insulating polyurethane foam, the formula contains functional particles. Although stirring can break up large agglomerates and decompose them into more and smaller agglomerates, the agglomerates still exist and cannot be completely dispersed to make the particles evenly distributed in the liquid.

[0005] 2. In the production of sound-insulating polyurethane foam, excessive stirring time and intensity result in excessively high viscosity of the mixed raw materials, which in turn affects the molding performance and quality of the sound-insulating polyurethane foam.

[0006] Therefore, existing sound-insulating polyurethane foam production equipment cannot meet the usage requirements. Summary of the Invention

[0007] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a sound insulation polyurethane foam production equipment and its usage method that can completely break up agglomerates, uniformly distribute particles in the liquid, and monitor the viscosity of raw materials in the mixture in real time to ensure the molding quality and performance of sound insulation polyurethane foam.

[0008] The technical solution adopted in this plan is as follows: A sound-insulating polyurethane foam production equipment is proposed, including a base, a mixing cylinder, a splash guard, an anti-clumping fine material mechanism, and a viscosity-measuring material handling mechanism. The mixing cylinder is located on the upper wall of the base and has an open top. The splash guard is connected to the upper wall of the mixing cylinder. The anti-clumping fine material mechanism is located on the mixing cylinder. The viscosity-measuring material handling mechanism is located on the anti-clumping fine material mechanism inside the mixing cylinder. The anti-clumping fine material mechanism includes a mixing component, a feeding component, and a crushing component. The mixing component is located at the bottom of the mixing cylinder. The feeding component is located on the upper wall of the base. The crushing component is located on the inner wall of the splash guard.

The closed-end component is located at the end of the crushing component near the splash guard. The air control component is located on the upper wall of the splash guard. The viscosity-measuring component is located at the end of the crushing component near the mixing cylinder.

[0009] As a further preferred embodiment of the present invention, the mixing assembly includes a waterproof motor and stirring blades. The waterproof motor is located on the bottom wall of the mixing cylinder, and the stirring blades are located on the power end of the waterproof motor. The feeding assembly includes a motor base, a pump, a suction pipe, a pipe clamp, and a feeding pipe. Multiple sets of the motor base are located on the upper wall of the base. The pump is located inside the motor base. Multiple sets of the pipe clamps are located on the side wall of the splash-proof cylinder. The feeding pipe passes through the pipe clamp and is connected between the discharge end of the pump and the top side wall of the splash-proof cylinder. The suction pipe passes through the motor base and is connected between the suction end of the pump and the mixing cylinder. The crushing assembly includes an arc-shaped slide, a vertical slide, and crushing holes. Multiple sets of the arc-shaped slide are located on the inner wall of the mixing cylinder. The vertical slide is located on the upper wall of the arc-shaped slide. The vertical slide and the feeding pipe are positioned opposite each other on the side near the splash-proof cylinder. The end of the vertical slide away from the arc-shaped slide is fixed to form a through triangular cavity. Multiple sets of crushing holes are located on the side wall of the vertical slide.

[0010] Preferably, the closed-end assembly includes a supporting mesh plate, a sliding plate, a triangular magnetic cylinder, a misaligned electromagnet, a limiting block, and a pneumatic control rod. The supporting mesh plate is disposed on the bottom wall of the through-hole triangular cavity. Multiple sets of sliding plates are slidably disposed on the inner wall of the through-hole triangular cavity. The triangular magnetic cylinder is disposed between the sliding plates. Multiple sets of misaligned electromagnets are disposed through-hole in the bottom wall of the supporting mesh plate. Multiple sets of limiting blocks are disposed on the upper wall of the triangular magnetic cylinder. Multiple sets of pneumatic control rods are respectively disposed through-hole in the side wall of the triangular magnetic cylinder, and the pneumatic control rods are slidably connected to the inner wall of the triangular magnetic cylinder. The pneumatic control assembly includes a pneumatic control pump, a pneumatic control pipe, and a telescopic pipe. The pneumatic control pump is disposed on the upper wall of the splash guard. The telescopic pipe passes through the splash guard and is connected to the upper wall of the triangular magnetic cylinder. The pneumatic control pipe is connected between the telescopic pipe and the pneumatic control end of the pneumatic control pump. The viscosity measuring assembly includes a feeding cylinder and a flow valve. The feeding cylinder is connected to the bottom wall of one end of the arc-shaped slide near the mixing cylinder. The flow valve is connected to the bottom wall of the feeding cylinder.

[0011] Specifically, the splash guard is equipped with a controller on its side wall.

[0012] The controller is electrically connected to the waterproof motor, the material pump, the misaligned electromagnet, the air control pump, and the flow valve.

[0013] The method of using a sound-insulating polyurethane foam production equipment is as follows:

[0014] Step 1: Pour the raw materials for producing sound-insulating polyurethane foam into the mixing drum. The waterproof motor drives the stirring blades to rotate, and the stirring blades stir the raw materials inside the mixing drum.

[0015] Step 2: The pump draws raw materials from inside the mixing cylinder through the pump pipe. The raw materials are then sprayed vertically onto the surface of the vertical slide through the feed pipe. The aggregated raw materials are reduced in volume after passing through the crushing hole, which allows the raw materials to be mixed evenly.

[0016] Step 3: The air pump expels the air from inside the triangular magnetic cylinder through the telescopic tube and the air control tube, changing the internal pressure of the triangular magnetic cylinder to a negative pressure state. The air control rod is drawn into the triangular magnetic cylinder and away from the crushing hole. The misaligned electromagnet is energized and generates magnetism. The misaligned electromagnet and the triangular magnetic cylinder are set with the same pole. The misaligned electromagnet is fixed to the bottom wall of the supporting mesh plate and pushes the triangular magnetic cylinder through repulsion. The triangular magnetic cylinder slides and rises along the through triangular cavity using the sliding plate. The triangular magnetic cylinder drives the limiting block to fit against the top wall of the splash guard. The air control rod enters the area between the crushing holes and is placed so that the raw material passing through the crushing holes contacts the side wall of the triangular magnetic cylinder. The raw material flows down into the mixing cylinder through the space between the triangular magnetic cylinder and the through triangular cavity.

[0017] Step 4: After the raw materials are crushed through the crushing hole, the operator observes that there are no obvious agglomerated particles in the mixing cylinder. The misaligned electromagnet is de-energized and demagnetized. The triangular magnetic cylinder descends along the inner wall of the through triangular cavity via the sliding plate. The bottom wall of the triangular magnetic cylinder is in contact with the upper wall of the supporting mesh plate. The triangular magnetic cylinder drives the air control rod to move and become coaxial and horizontal with the crushing hole. The air control pump injects air into the triangular magnetic cylinder through the air control pipe and the telescopic pipe. The air pressure inside the triangular magnetic cylinder increases and pushes the air control rod. The air control rod slides along its inner wall and inserts into the crushing hole to seal the crushing hole.

[0018] Step 5: The raw material sprayed vertically from the extraction pipe onto the side wall of the vertical slide cannot pass through the blocked fragmentation hole. Some of the raw material splashes out of the vertical slide and falls into the bottom of the mixing cylinder due to the rebound of the vertical slide; the other part of the raw material enters the arc-shaped slide under the guidance of the vertical slide, and flows down the inner wall of the arc-shaped slide into the discharge cylinder. After passing through the flow valve, the raw material falls into the mixing cylinder.

[0019] Step Six: The flow valve monitors the flow rate of the raw materials in real time. In the production of sound-insulating polyurethane foam, the formula contains functional particles. After the liquid raw materials and the granular raw materials are mixed together to form a slurry, the viscosity of the mixed raw materials will increase significantly during the stirring process. The rebound or splashing phenomenon generated after the raw materials are sprayed onto the vertical slide surface will be greatly reduced, which will increase the flow rate of the raw materials flowing through the flow valve. When the operator observes that the raw materials flowing through the flow valve have reached the preset value, the stirring of the raw materials will be stopped.

[0020] The beneficial effects achieved by this solution using the above structure are as follows:

[0021] Compared with existing technologies, this solution combines an anti-agglomeration fine material mechanism with a viscosity-measuring material feeding mechanism. Through the setting of mixing components, feeding components, crushing components, closing components, air control components, and viscosity measuring components, the viscosity of the raw materials can be monitored during the mixing process. This ensures both uniform mixing between liquid and granular raw materials and prevents over-mixing, thus avoiding excessively high viscosity. Furthermore, the material crushing holes disperse the raw materials, breaking up any agglomeration between granular materials and ensuring that the granular materials are evenly distributed in the liquid raw materials. This lays the foundation for the subsequent production of high-performance sound insulation foam. Attached Figure Description

Multiple sets of the arc-shaped slide 15 are provided on the inner wall of the mixing cylinder 2, and the vertical slide 16 is provided on the upper wall of the arc-shaped slide 15. The vertical slide 16 and the side of the feeding pipe 13 near the splash guard 3 are opposite each other. The end of the vertical slide 16 away from the arc-shaped slide 15 is fixed to form a through triangular cavity, and multiple sets of crushing holes 17 are provided on the sidewall of the vertical slide 16.

[0041] Preferably, the closed assembly 19 includes a supporting mesh plate 20, a sliding plate 21, a triangular magnetic cylinder 22, a misaligned electromagnet 23, a limiting block 24, and a pneumatic control rod 33. The supporting mesh plate 20 is disposed on the bottom wall of the through triangular cavity, multiple sets of sliding plates 21 are slidably disposed on the inner wall of the through triangular cavity, the triangular magnetic cylinder 22 is disposed between the sliding plates 21, multiple sets of misaligned electromagnets 23 are disposed through the bottom wall of the supporting mesh plate 20, multiple sets of limiting blocks 24 are disposed on the upper wall of the triangular magnetic cylinder 22, and multiple sets of pneumatic control rods 33 are respectively disposed through the side walls of the triangular magnetic cylinder 22. The rod 33 is slidably connected to the inner wall of the triangular magnetic cylinder 22; the air control assembly 25 includes an air control pump 26, an air control pipe 27, and a telescopic pipe 28. The air control pump 26 is located on the upper wall of the splash shield 3, the telescopic pipe 28 passes through the splash shield 3 and is connected to the upper wall of the triangular magnetic cylinder 22, and the air control pipe 27 is connected between the telescopic pipe 28 and the air control end of the air control pump 26; the viscosity measuring assembly 29 includes a feeding cylinder 30 and a flow valve 31. The feeding cylinder 30 is connected to the bottom wall of one end of the arc-shaped slide 15 near the mixing cylinder 2, and the flow valve 31 is connected to the bottom wall of the feeding cylinder 30.

[0042] Specifically, the splash guard 3 is provided with a controller 32 on its side wall.

[0043] The controller 32 is electrically connected to the waterproof motor 6, the material pump 10, the misaligned electromagnet 23, the air pump 26, and the flow valve 31.

[0044] The method of using a sound-insulating polyurethane foam production equipment is as follows:

[0045] Step 1: Pour the raw materials for producing sound-insulating polyurethane foam into the mixing cylinder 2. The power end of the waterproof motor 6 drives the stirring blades 7 to rotate, and the stirring blades 7 stir the raw materials inside the mixing cylinder 2.

[0046] Step 2: The pump 10 extracts the raw materials inside the mixing cylinder 2 through the extraction pipe 11. The raw materials are then sprayed vertically onto the surface of the vertical slide 16 through the feed pipe 13. The agglomerated raw materials are reduced in volume after passing through the crushing hole 17, so that the raw materials can be mixed evenly.

[0047] Step 3: The air pump 26 discharges the air inside the triangular magnetic cylinder 22 through the telescopic tube 28 and the air control tube 27, changing the internal pressure of the triangular magnetic cylinder 22 to a negative pressure state. The air control rod 33 is drawn into the triangular magnetic cylinder 22 and away from the crushing hole 17. The misaligned electromagnet 23 is energized and generates magnetism. The misaligned electromagnet 23 and the triangular magnetic cylinder 22 are set with the same pole. The misaligned electromagnet 23 is fixed to the bottom wall of the supporting mesh plate 20 and pushes the triangular magnetic cylinder 22 through repulsion. The triangular magnetic cylinder 22 slides and rises along the through triangular cavity using the sliding plate 21. The triangular magnetic cylinder 22 drives the limiting block 24 to fit against the top wall of the splash guard 3. The air control rod 33 enters the area between the crushing holes 17 and is placed so that the raw material passing through the crushing hole 17 contacts the side wall of the triangular magnetic cylinder 22. The raw material flows down into the mixing cylinder 2 through the space between the triangular magnetic cylinder 22 and the through triangular cavity.

[0048] Step 4: After the raw material is crushed through the crushing hole 17, the operator observes that there are no obvious agglomerated particles in the mixing cylinder 2. The misaligned electromagnet 23 is de-energized and demagnetized. The triangular magnetic cylinder 22 descends along the inner wall of the through triangular cavity via the sliding plate 21. The bottom wall of the triangular magnetic cylinder 22 is in contact with the upper wall of the supporting mesh plate 20. The triangular magnetic cylinder 22 drives the air control rod 33 to move and be coaxial and horizontal with the crushing hole 17. The air control pump 26 injects air into the triangular magnetic cylinder 22 through the air control pipe 27 and the telescopic pipe 28. The air pressure inside the triangular magnetic cylinder 22 increases and pushes the air control rod 33. The air control rod 33 slides along its inner wall and inserts into the crushing hole 17 to seal the crushing hole 17.

[0049] Step 5: The raw material sprayed vertically from the extraction pipe 11 onto the side wall of the vertical slide 16 cannot pass through the blocked crushing hole 17. Part of the raw material splashes out of the vertical slide 16 and falls into the bottom of the mixing cylinder 2 due to the rebound of the vertical slide 16; another part of the raw material enters the arc-shaped slide 15 under the guidance of the vertical slide 16. The raw material flows down along the inner wall of the arc-shaped slide 15 and enters the discharge cylinder 30. After passing through the flow valve 31, the raw material falls into the mixing cylinder 2.

[0050] Step Six: Flow valve 31 monitors the flow rate of the raw materials in real time. In the production of sound-insulating polyurethane foam, the formula contains functional particles. After the liquid raw materials and the granular raw materials are mixed together to form a slurry, the viscosity of the mixed raw materials will increase significantly during the stirring process. The rebound or splashing phenomenon generated after the raw materials are sprayed onto the surface of the vertical slide 16 will be greatly reduced, which will increase the flow rate of the raw materials flowing through flow valve 31. When the operator observes that the raw materials flowing through flow valve 31 have reached the preset value, the stirring of the raw materials will be stopped.

[0051] In actual use, in the initial state, the triangular magnetic cylinder 22 is attached to the upper wall of the supporting mesh plate 20, and the air control rod 33 is coaxially and horizontally set with the crushing hole 17, with the air control rod 33 located inside the crushing hole 17.

[0052] The liquid raw material and granular raw material for the production of sound insulation polyurethane foam are poured into the mixing cylinder 2 respectively. The controller 32 controls the waterproof motor 6 to start. The power end of the waterproof motor 6 drives the stirring blade 7 to rotate. The stirring blade 7 stirs the liquid raw material and granular raw material inside the mixing cylinder 2.

[0053] To break up agglomerates in the raw materials and ensure uniform mixing of liquid and granular materials, controller 32 controls air pump 26. Air pump 26 expels air from inside triangular magnetic cylinder 22 through telescopic tube 28 and air control tube 27, changing the internal pressure of triangular magnetic cylinder 22 to negative pressure. Air control rod 33 is drawn into the triangular magnetic cylinder 22 and away from the crushing hole 17. Controller 32 controls the misalignment electromagnet 23 to start. Misalignment electromagnet 23 generates magnetism when energized. Misalignment electromagnet 23 and triangular magnetic cylinder 22 are set with the same pole. Misalignment electromagnet 23 is fixed to the bottom wall of support mesh plate 20 and pushes triangular magnetic cylinder 22 through repulsion. Triangular magnetic cylinder 22 slides and rises along the through triangular cavity using sliding plate 21. Triangular magnetic cylinder 22 drives limit block 24 to fit against the top wall of splash shield 3. Air control rod 33 enters the area between crushing holes 17 and is placed there. Misalignment is formed between air control rod 33 and crushing hole 17.

[0054] The controller 32 controls the start of the material pump 10. The material pump 10 draws the raw material inside the mixing cylinder 2 through the material extraction pipe 11. The raw material is sprayed vertically onto the surface of the vertical slide 16 through the feeding pipe 13. The agglomerated raw material passes through the crushing hole 17 and its volume is reduced. It then contacts the side wall of the triangular magnetic cylinder 22. The raw material flows down through the space between the triangular magnetic cylinder 22 and the through triangular cavity. After passing through the support mesh plate 20, it returns to the inside of the mixing cylinder 2.

[0055] After the raw material is crushed through the crushing hole 17, the controller 32 controls the misaligned electromagnet 23 to be de-energized and demagnetized. The triangular magnetic cylinder 22 descends along the inner wall of the through triangular cavity via the sliding plate 21. The bottom wall of the triangular magnetic cylinder 22 is in contact with the upper wall of the supporting mesh plate 20. The triangular magnetic cylinder 22 drives the air control rod 33 to move and be coaxial and horizontal with the crushing hole 17. The controller 32 controls the air control pump 26 to start. The air control pump 26 injects air into the triangular magnetic cylinder 22 through the air control pipe 27 and the telescopic pipe 28. After the air pressure inside the triangular magnetic cylinder 22 increases, it pushes the air control rod 33. The air control rod 33 slides along its inner wall and inserts into the crushing hole 17 to seal the crushing hole 17.

[0056] The raw material sprayed vertically from the extraction pipe 11 toward the side wall of the vertical slide 16 cannot pass through the blocked crushing hole 17. Some of the raw material bounces and splashes after colliding with the vertical slide 16 and falls into the mixing cylinder 2. The other part of the raw material enters the arc-shaped slide 15 under the guidance of the vertical slide 16. The raw material flows down along the inner wall of the arc-shaped slide 15 and enters the discharge cylinder 30. After passing through the raw material flow valve 31, it falls into the mixing cylinder 2.

[0057] The flow valve 31 monitors the flow rate of the raw materials in real time. In the production of sound-insulating polyurethane foam, the formula contains functional particles. After the liquid raw materials and the granular raw materials are mixed together to form a slurry, the viscosity of the mixed raw materials will increase significantly during the stirring process. The rebound and splashing phenomena generated after the raw materials are sprayed onto the surface of the vertical slide 16 will be greatly reduced, which will increase the flow rate of the raw materials flowing down the arc slide 15 through the flow valve 31. When the operator observes that the raw materials flowing through the flow valve 31 have reached the preset flow rate value, the stirring of the raw materials will be stopped, and the mixing operation of the sound-insulating polyurethane foam raw materials will be completed. The above operation can be repeated for the next use.

Step 2: The pump extracts the raw material from inside the mixing cylinder through the extraction pipe. The raw material is then sprayed vertically onto the surface of the vertical slide through the feed pipe. The aggregated raw material is reduced in volume after passing through the crushing hole. Step 3: The air pump expels the air from inside the triangular magnetic cylinder through the telescopic tube and the air control tube, changing the internal pressure of the triangular magnetic cylinder to a negative pressure state. The air control rod is drawn into the triangular magnetic cylinder and away from the crushing hole. The misaligned electromagnet is energized and generates magnetism. The misaligned electromagnet and the triangular magnetic cylinder are set with the same pole. The misaligned electromagnet is fixed to the bottom wall of the supporting mesh plate and pushes the triangular magnetic cylinder through repulsion. The triangular magnetic cylinder slides and rises along the through triangular cavity using the sliding plate. The triangular magnetic cylinder drives the limiting block to fit against the top wall of the splash guard. The air control rod enters the area between the crushing holes and is placed so that the raw material passing through the crushing holes contacts the side wall of the triangular magnetic cylinder. The raw material flows down into the mixing cylinder through the space between the triangular magnetic cylinder and the through triangular cavity. Step 4: After the raw materials are crushed through the crushing hole, the operator observes that there are no obvious agglomerated particles in the mixing cylinder. The misaligned electromagnet is de-energized and demagnetized. The triangular magnetic cylinder descends along the inner wall of the through triangular cavity via the sliding plate. The bottom wall of the triangular magnetic cylinder is in contact with the upper wall of the supporting mesh plate. The triangular magnetic cylinder drives the air control rod to move and become coaxial and horizontal with the crushing hole. The air control pump injects air into the triangular magnetic cylinder through the air control pipe and the telescopic pipe. The air pressure inside the triangular magnetic cylinder increases and pushes the air control rod. The air control rod slides along its inner wall and inserts into the crushing hole to seal the crushing hole. Step 5: The raw material sprayed vertically from the extraction pipe onto the side wall of the vertical slide cannot pass through the blocked fragmentation hole. Some of the raw material splashes out of the vertical slide and falls into the bottom of the mixing cylinder due to the rebound of the vertical slide; the other part of the raw material enters the arc-shaped slide under the guidance of the vertical slide, flows down the inner wall of the arc-shaped slide and enters the discharge cylinder, and falls into the mixing cylinder after passing through the flow valve. Step Six: The flow valve monitors the flow rate of the raw materials in real time. In the production of sound-insulating polyurethane foam, the formula contains functional particles. After the liquid raw materials and the granular raw materials are mixed together to form a slurry, the viscosity of the mixed raw materials will increase significantly during the stirring process. The rebound or splashing phenomenon generated after the raw materials are sprayed onto the vertical slide surface will be greatly reduced, which will increase the flow rate of the raw materials flowing through the flow valve. When the operator observes that the raw materials flowing through the flow valve have reached the preset value, the stirring of the raw materials will be stopped.
