Description

Technical Field

[0001] This utility model belongs to the technical field of polyurethane processing equipment, and more specifically, it relates to a multi-channel mixer for a continuous polyurethane foaming machine. Background Technology

[0002] Polyurethane is short for polyurethane, a type of polymer material. Polyurethane is a new type of organic polymer material, known as the "fifth largest plastic". Due to its excellent performance, it is widely used in many sectors of the national economy, including light industry, chemical industry, electronics, textiles, medical, construction, building materials, automobiles, defense, aerospace, and aviation.

[0003] Rigid polyurethane foam is a high molecular polymer made from isocyanate and polyether as the main raw materials. Under the action of various additives such as foaming agents, catalysts, and flame retardants, the polyurethane mixture is fully mixed in a continuous mixing and foaming device and then foamed on-site by high-pressure spraying.

[0004] During the polyurethane mixing process, localized agglomerates often form in the polyurethane solution due to differences in raw material viscosity and uneven dispersion of additives. Existing continuous polyurethane mixing and foaming equipment typically uses rotating impellers or rods to agitate the polyurethane solution. However, this method is insufficient to break up agglomerates, thus affecting the subsequent foaming quality and reducing the practicality of the continuous polyurethane mixing and foaming equipment.

[0005] In the polyurethane mixing process, localized agglomeration of particles often occurs in the polyurethane solution due to differences in raw material viscosity and uneven dispersion of additives.

Materials are added to the foaming machine tank through the feeding mechanisms. The grinding mechanism crushes and grinds agglomerated particles in the polyurethane mixture within the tank. A mixing mechanism is installed on the grinding mechanism to mix and agitate the polyurethane mixture. The drive mechanism drives the mixing mechanism and the grinding mechanism to operate.

[0008] Furthermore, the feeding mechanism includes a connecting pipe, which is fixedly connected to the outer surface of the foaming machine tank and communicates with the interior of the foaming machine tank. A fixing frame is fixedly connected to the outer surface of the foaming machine tank, and the fixing frame is fixedly connected to the outer surface of the storage tank. The upper end of the connecting pipe is fixedly connected to the storage tank, and the connecting pipe communicates with the interior of the storage tank. The interior of the storage tank is hollow, and a cover is threadedly connected to the upper side of the storage tank. A solenoid valve is provided on the connecting pipe.

[0009] Furthermore, the driving mechanism includes two mounting rods, which are fixedly connected to the upper surface of the foaming machine tank. A positioning block is fixedly connected to the upper end of each of the two mounting rods. A rotary motor is fixedly connected to the upper surface of the positioning block. A through groove extending from the lower surface of the positioning block is formed on the upper surface of the positioning block. The rotation output shaft of the rotary motor extends from the lower surface of the positioning block through the through groove. A hexagonal sliding column is fixedly connected to the rotation output shaft of the rotary motor.

[0010] Furthermore, the grinding mechanism includes a positioning column, the upper surface of which is provided with a positioning groove, the positioning groove being hexagonal prism in shape, the hexagonal prism being adapted to the positioning groove, the hexagonal prism being slidably connected to the positioning groove, the lower surface of the hexagonal prism being slidably extended into the positioning groove, and a stirring rod being fixedly connected to the lower surface of the positioning column, the lower end of the stirring rod passing through the sliding ring and slidingly penetrating into the foaming machine tank.

[0011] Furthermore, the inner wall of the sliding ring is provided with a slide rail groove, and a sliding block is fixedly connected to the outer surface of the positioning post. The end of the sliding block away from the positioning post extends into the slide rail groove and is slidably connected to the upper and lower inner walls of the slide rail groove. The lower end of the stirring rod is fixedly connected to an extrusion hemisphere. The inner wall of the extrusion hemisphere is provided with multiple connecting grooves extending out of its lower surface. The lower surface of the extrusion hemisphere is slidably connected to the bottom wall of the foaming machine tank.

[0012] Furthermore, the mixing mechanism includes multiple mixing rods, which are fixedly connected to the outer surface of the stirring rod and located inside the foaming machine tank. Two scraper rods are fixedly connected to the upper surface of the extrusion hemisphere.

[0014] This utility model has the following beneficial effects:

[0015] This invention squeezes some of the agglomerated particles in the polyurethane liquid between the lower surface of the extrusion hemisphere and the bottom wall of the foaming machine tank. As the extrusion hemisphere rotates downwards, it can crush and grind the agglomerated particles in the polyurethane liquid, thereby greatly reducing the number of agglomerated particles in the polyurethane liquid and ensuring the uniformity of the polyurethane liquid mixing, thus ensuring the foaming quality of the polyurethane.

[0016] This invention utilizes a stirring rod that rotates and moves up and down simultaneously, which in turn drives a mixing rod to rotate and stir. This rotation and movement of the mixing plate also increases convection between the polyurethane liquid on the upper and lower sides of the foaming machine tank. This enhances the mixing effect and allows the polyurethane liquid to flow between the lower surface of the extrusion hemisphere and the bottom wall of the foaming machine tank. This process crushes and breaks up agglomerated particles in the polyurethane liquid, thereby increasing the practicality and efficiency of the continuous polyurethane foaming machine.

[0017] This invention allows the raw materials in the corresponding storage tank to flow into the connecting pipe by activating the solenoid valve on the connecting pipe, eliminating the need for manual feeding. It also enables the addition of materials to the foaming machine tank through multiple channels, making it convenient to operate, saving manpower, and thus enhancing the practicality of the multi-channel mixer for continuous polyurethane foaming machines.

[0018] As the extrusion hemisphere rotates and moves up and down, the scraper of this invention cleans the inner wall of the foaming machine tank, preventing raw materials from sticking to the inner wall of the foaming machine tank. This further ensures the uniformity of polyurethane liquid mixing and increases the practicality of the continuous polyurethane foaming machine.

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-6 As shown, this utility model is a multi-channel mixer for a continuous polyurethane foaming machine, including a foaming machine tank 1. Multiple support frames 2 are fixedly connected to the lower surface of the foaming machine tank 1. Multiple feeding mechanisms are provided on the foaming machine tank 1, and each feeding mechanism communicates with the interior of the foaming machine tank 1. The feeding mechanisms are used to store different materials. A driving mechanism is provided on the foaming machine tank 1. A sliding ring 7 is fixedly connected to the upper surface of the foaming machine tank 1. A grinding mechanism is provided on the sliding ring 7. Materials are added to the foaming machine tank 1 through the feeding mechanisms. The grinding mechanism crushes and grinds agglomerated particles in the polyurethane mixture within the foaming machine tank 1. A mixing mechanism is provided on the grinding mechanism to mix and agitate the polyurethane mixture. The driving mechanism drives the mixing mechanism and the grinding mechanism to operate.

[0032] The drive mechanism is activated, which drives the grinding mechanism to rotate. With the cooperation of the grinding mechanism and the sliding ring 7, the grinding mechanism rotates and moves up and down simultaneously. During the downward movement of the grinding mechanism, the agglomerated particles in the polyurethane mixture are squeezed and ground between the grinding mechanism and the bottom wall of the foaming machine tank 1, thereby effectively reducing the agglomerated particles in the polyurethane mixture. At the same time, the rotation and up-and-down movement of the grinding mechanism also drive the mixing mechanism to rotate and move up and down, thereby mixing and agitating the polyurethane mixture in the foaming machine tank 1, making the polyurethane mixture more uniform.

[0033] In one embodiment, the feeding mechanism includes a connecting pipe 3, which is fixedly connected to the outer surface of the foaming machine tank 1 and communicates with the interior of the foaming machine tank 1. A fixing frame 4 is fixedly connected to the outer surface of the foaming machine tank 1, and the fixing frame 4 is fixedly connected to the outer surface of the storage tank 5. The upper end of the connecting pipe 3 is fixedly connected to the storage tank 5, and the connecting pipe 3 communicates with the interior of the storage tank 5. The interior of the storage tank 5 is hollow, and a cover 6 is threadedly connected to the upper side of the storage tank 5. A solenoid valve is provided on the connecting pipe 3.

[0034] Furthermore, in practical applications, various raw materials that need to be added are poured into the corresponding storage tanks 5 according to appropriate specifications or weights. During the mixing and stirring process of the polyurethane liquid in the foaming machine tank 1, the solenoid valve on the connecting pipe 3 is activated, so that the raw materials in the corresponding storage tanks 5 flow into the connecting pipe 3. No manual feeding is required, and materials can be added to the foaming machine tank 1 through multiple channels. The operation is convenient and saves manpower, thus demonstrating the practicality of the multi-channel mixer of the polyurethane continuous foaming machine.

[0035] In one embodiment, the driving mechanism includes two mounting rods 8, which are fixedly connected to the upper surface of the foaming machine tank 1. A positioning block 9 is fixedly connected to the upper end of the two mounting rods 8. A rotary motor 10 is fixedly connected to the upper surface of the positioning block 9. A through groove extending from the lower surface of the positioning block 9 is provided on the upper surface of the positioning block 9. The rotation output shaft of the rotary motor 10 extends from the lower surface of the positioning block 9 through the through groove. A hexagonal sliding column 11 is fixedly connected to the rotation output shaft of the rotary motor 10.

[0036] When the rotating motor 10 is started, the rotating motor 10 drives the hexagonal sliding column 11 to rotate.

[0037] In one embodiment, the grinding mechanism includes a positioning column 12, the upper surface of which is provided with a positioning groove 13, the positioning groove 13 being hexagonal prism in shape, a hexagonal sliding column 11 adapted to the positioning groove 13, the hexagonal sliding column 11 being slidably connected to the positioning groove 13, the lower surface of the hexagonal sliding column 11 slidably extending into the positioning groove 13, and a stirring rod 14 fixedly connected to the lower surface of the positioning column 12, the lower end of the stirring rod 14 passing through the sliding ring 7 and slidingly penetrating into the foaming machine tank 1.

[0038] The inner wall of the sliding ring 7 is provided with a slide rail groove 16. The outer surface of the positioning post 12 is fixedly connected with a sliding block 15. The end of the sliding block 15 away from the positioning post 12 extends into the slide rail groove 16 and is slidably connected to the upper and lower inner walls of the slide rail groove 16. The lower end of the stirring rod 14 is fixedly connected with an extrusion hemisphere 18. The inner wall of the extrusion hemisphere 18 is provided with a plurality of connecting grooves 19 extending out of its lower surface. The lower surface of the extrusion hemisphere 18 is slidably connected to the bottom wall of the foaming machine tank 1.

[0039] Because the hexagonal sliding column 11 is hexagonal in shape, its rotation synchronously drives the positioning column 12 to rotate. The positioning column 12's rotation, in turn, drives the stirring rod 14, sliding block 15, and extrusion hemisphere 18 to rotate. Since the sliding block 15 is slidably connected to the slide rail groove 16 during rotation, it also moves up and down with the groove, thus causing the stirring rod 14 and extrusion hemisphere 18 to rotate and move up and down simultaneously. During this up-and-down movement, some of the polyurethane liquid flows into the extrusion hemisphere 18. Between the lower surface of the extrusion hemisphere 18 and the bottom wall of the foaming machine tank 1, when the extrusion hemisphere 18 is moved to its lowest position, the lower surface of the extrusion hemisphere 18 contacts the bottom wall of the foaming machine tank 1, thereby squeezing some of the agglomerated particles in the polyurethane liquid between the lower surface of the extrusion hemisphere 18 and the bottom wall of the foaming machine tank 1. As the extrusion hemisphere 18 rotates downward, it can squeeze and grind the agglomerated particles in the polyurethane liquid, thereby greatly reducing the agglomerated particles in the polyurethane liquid, thus ensuring the uniformity of the polyurethane liquid mixing, and thus ensuring the foaming quality of the polyurethane.

[0040] In one embodiment, the mixing mechanism includes a plurality of mixing rods 17, which are fixedly connected to the outer surface of the stirring rod 14 and located inside the foaming machine tank 1. Two scraper rods 20 are fixedly connected to the upper surface of the extrusion hemisphere 18.

[0041] The outer surfaces of the two opposing sides of the scraper 20 are in contact with the inner wall of the foaming machine tank 1. The scraper 20 is slidably connected to the inner wall of the foaming machine tank 1. A mixing plate 21 is provided inside the foaming machine tank 1. The mixing plate 21 is spiral in shape. The lower end of the mixing plate 21 is fixedly connected to the inner wall of the extrusion hemisphere 18. The upper end of the mixing plate 21 is fixedly connected to the outer surface of any of the mixing rods 17.

[0042] As the stirring rod 14 rotates and moves up and down, it simultaneously drives the mixing rod 17 to rotate and stir, and also drives the mixing plate 21 to rotate and move up and down. During the rotation and up and down movement of the mixing plate 21, the convection between the polyurethane liquid mixture located on the upper side of the foaming machine tank 1 and the polyurethane liquid mixture located on the lower side of the foaming machine tank 1 can be increased. On the one hand, this can increase the mixing effect, and on the other hand, it can drive the polyurethane liquid mixture to flow between the lower surface of the extrusion hemisphere 18 and the bottom wall of the foaming machine tank 1, thereby extruding and grinding the agglomerated particles in the polyurethane liquid, thereby increasing the practicality of the polyurethane continuous foaming machine and improving its working efficiency.

[0043] In this design, as the scraper 20 rotates and moves up and down with the extrusion hemisphere 18, the scraper 20 cleans the inner wall of the foaming machine tank 1 during this process, preventing raw materials from sticking to the inner wall of the foaming machine tank 1, further ensuring the uniformity of polyurethane liquid mixing, and increasing the practicality of the continuous polyurethane foaming machine.

[0044] In this design, the rotating motor 10 is a self-locking motor, such as a conical rotor motor, so that after the rotating motor 10 stops stirring, the extruded hemisphere 18 will not fall with gravity and block the discharge port on the lower side of the foaming machine tank 1.

[0045] In summary, by utilizing the above-mentioned technical solution of this utility model, by pouring various raw materials to be added into the corresponding storage tanks 5 according to appropriate specifications or weights, during the mixing and stirring process of the polyurethane liquid in the foaming machine tank 1, the solenoid valve on the connecting pipe 3 is activated, allowing the raw materials in the corresponding storage tanks 5 to flow into the connecting pipe 3. No manual feeding is required, and materials can be added to the foaming machine tank 1 through multiple channels. When the rotating motor 10 is started, the rotating motor 10 drives the hexagonal sliding column 11 to rotate. Because the hexagonal sliding column 11 is hexagonal... Because of its cylindrical shape, the rotation of the hexagonal sliding column 11 synchronously drives the positioning column 12 to rotate. The rotation of the positioning column 12 synchronously drives the stirring rod 14, the sliding block 15, and the extrusion hemisphere 18 to rotate. Since the sliding block 15 is slidably connected to the slide rail groove 16 during rotation, it also moves up and down with the slide rail groove 16. This causes the stirring rod 14 and the extrusion hemisphere 18 to rotate and move up and down simultaneously. During the up-and-down movement of the extrusion hemisphere 18, some of the polyurethane liquid will flow into it. Between the lower surface of the extrusion hemisphere 18 and the bottom wall of the foaming machine tank 1, when the extrusion hemisphere 18 moves to its lowest position, the lower surface of the extrusion hemisphere 18 contacts the bottom wall of the foaming machine tank 1, thereby squeezing some of the agglomerated particles in the polyurethane liquid between the lower surface of the extrusion hemisphere 18 and the bottom wall of the foaming machine tank 1. As the extrusion hemisphere 18 rotates downward, it can squeeze and grind the agglomerated particles in the polyurethane liquid, thereby greatly reducing the agglomerated particles in the polyurethane liquid. Meanwhile, as the stirring rod 14 rotates and moves up and down, it will simultaneously carry... The rotating mixing rod 17 stirs the mixture and also causes the mixing plate 21 to rotate and move up and down. During the rotation and up and down movement of the mixing plate 21, the convection between the polyurethane liquid on the upper side and the polyurethane liquid on the lower side of the foaming machine tank 1 is increased. On the one hand, this increases the mixing effect, and on the other hand, it drives the polyurethane liquid to flow between the lower surface of the extrusion hemisphere 18 and the bottom wall of the foaming machine tank 1, thereby extruding and grinding the agglomerated particles in the polyurethane liquid, thus increasing the practicality of the continuous polyurethane foaming machine.

[0046] Through the above technical solution, 1. by squeezing some of the agglomerated particles in the polyurethane liquid between the lower surface of the extrusion hemisphere 18 and the bottom wall of the foaming machine tank 1, the agglomerated particles in the polyurethane liquid can be squeezed and ground during the downward rotation of the extrusion hemisphere 18, thereby greatly reducing the agglomerated particles in the polyurethane liquid, thus ensuring the uniformity of the polyurethane liquid mixing, and thus ensuring the foaming quality of polyurethane.

[0047] As the stirring rod 14 rotates and moves up and down, it simultaneously drives the mixing rod 17 to rotate and stir, and also drives the mixing plate 21 to rotate and move up and down. During the rotation and up and down movement of the mixing plate 21, the convection between the polyurethane liquid on the upper side and the polyurethane liquid on the lower side of the foaming machine tank 1 can be increased. On the one hand, this can increase the mixing effect, and on the other hand, it can drive the polyurethane liquid to flow to the lower surface of the extrusion hemisphere 18 and the bottom wall of the foaming machine tank 1, thereby extruding and grinding the agglomerated particles in the polyurethane liquid, thus increasing the practicality of the polyurethane continuous foaming machine and improving its working efficiency.

[0048] By activating the solenoid valve on the connecting pipe 3, the raw material in the corresponding storage tank 5 flows into the connecting pipe 3, eliminating the need for manual feeding. Furthermore, it allows for the addition of materials to the foaming machine tank 1 through multiple channels, making operation convenient, saving manpower, and thus enhancing the practicality of the multi-channel mixer in the polyurethane continuous foaming machine.

[0049] As the extrusion hemisphere 18 rotates and moves up and down, the scraper 20 scrapes the inner wall of the foaming machine tank 1 to prevent raw materials from sticking to the inner wall of the foaming machine tank 1, thereby ensuring the uniformity of polyurethane liquid mixing and increasing the practicality of the continuous polyurethane foaming machine.
