Description

Technical Field

[0001] This utility model belongs to the field of foaming machine technology, and specifically relates to a raw material proportioning and mixing device for a polyurethane foaming machine. Background Technology

[0002] Polyurethane foaming machines are the core equipment used to produce polyurethane foam. Their raw materials mainly include isocyanates and polyols, as well as auxiliary materials. By adjusting the raw material ratio and the types of additives, polyurethane foaming machines can produce products that meet different performance requirements and are widely used in construction, automobiles, home appliances and other fields.

[0003] In existing technologies, multiple raw materials are generally metered and transported by metering pumps, so that the multiple raw materials are mixed inside the mixing head. However, when multiple raw materials are mixed in the internal flow channel of the mixing head, the contact time between the multiple raw materials is short, which makes it impossible to mix them fully. This results in uneven foam texture in some areas, which reduces the foaming quality. Utility Model Content

[0004] To address the problem that when multiple raw materials are mixed in the internal flow channel of the mixing head, the contact time between the raw materials is often short, resulting in insufficient mixing and uneven foam consistency, which reduces the foaming quality, this utility model proposes a raw material proportioning and mixing device for a polyurethane foaming machine to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a raw material proportioning and mixing device for a polyurethane foaming machine, including a mounting frame:

[0007] The mounting frame is respectively equipped with a proportioning component, a driving component, a transmission component, a mixing component, and a sealing component;

[0008] The proportioning component is internally connected to the mixing component, so that the proportioning component can deliver a certain amount of raw materials into the mixing component for mixing;

[0009] The drive component has its output end fixedly installed inside the transmission component, so that the drive component drives the transmission component to operate.

[0010] The mixing component is fixedly installed on its outer surface and inside the transmission component, so that when the transmission component is running, it drives the mixing component to convey and mix the raw materials.

[0011] The sealing assembly has its bottom end fixedly connected to the inner side of the mixing assembly, so that the sealing assembly seals the mixing assembly.

[0012] Furthermore, the proportioning component includes a first proportioning container and a second proportioning container. The bottom ends of both the first and second proportioning containers are fixedly installed to the top end of the mounting frame, and connecting pipes are fixedly connected inside both the first and second proportioning containers.

[0013] Furthermore, the drive assembly includes a support frame, the bottom end of which is fixedly mounted to the top end of the mounting frame, and a motor is fixedly mounted on the inner side of the support frame.

[0014] Furthermore, the transmission assembly includes a drive gear, the interior of which is fixedly installed with the output end of the motor, and a driven gear is meshed with the surface of the drive gear.

[0015] Furthermore, the mixing assembly includes a lower housing, the bottom end of which is fixedly installed to the top end of the mounting bracket, and an upper housing fixedly installed to the top end of the lower housing. A connecting shaft is rotatably provided inside both the lower and upper housings, and the outer surface of the connecting shaft is fixedly installed to the interior of the driven gear. The interiors of the lower and upper housings are connected to the interior of the connecting pipe.

[0016] Furthermore, the mixing assembly also includes a mixing ball, the interior of which is fixedly connected to the outer surface of the connecting shaft, the outer surface of which is in contact with the inner walls of the lower and upper housings, and a mixing groove is formed on the outer surface of the mixing ball.

[0017] Furthermore, the sealing assembly includes a sealing groove, which is formed at the bottom end of the upper housing. A sealing strip is sealed inside the sealing groove, and the bottom end of the sealing strip is fixedly connected to the top end of the lower housing.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model drives the transmission component installed at the output end of the start-up drive component to operate, so that the transmission component drives the mixing component installed inside to operate, so that the mixing component mixes different raw materials. Since the mixing component has multiple mixing chambers inside, the mixing time between different raw materials can be increased, thereby ensuring that the different raw materials are fully mixed and improving the foaming quality.

[0020] 2. This utility model uses a driven gear to drive the internally installed connecting shaft to rotate, which in turn drives the mixing balls installed on the outer surface to rotate. Since the outer surface of the mixing balls is in contact with the inner wall of the cavity after the lower and upper shells are installed, and the outer surface of the mixing balls has a mixing groove, multiple sets of mixing balls can divide the cavity. As the mixing balls drive the mixing groove to rotate, the raw materials entering the cavity can be gradually driven into different cavities and mixed inside the cavity. This increases the mixing time between the raw materials and ensures that the raw materials are fully mixed.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0032] 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.

[0033] Please see Figures 1-6 As shown, this utility model is a raw material proportioning and mixing device for a polyurethane foaming machine, including a mounting frame 1:

[0034] The mounting frame 1 is respectively equipped with a proportioning component 2, a driving component 3, a transmission component 4, a mixing component 5, and a sealing component 6;

[0035] The proportioning component 2 is internally connected to the mixing component 5, so that the proportioning component 2 can deliver a certain amount of raw materials into the mixing component 5 for mixing;

[0036] The output end of the drive component 3 is fixedly installed inside the transmission component 4 so that the drive component 3 drives the transmission component 4 to operate.

[0037] The mixing component 5 is fixedly installed on its outer surface and inside the transmission component 4, so that when the transmission component 4 is running, it drives the mixing component 5 to convey and mix the raw materials.

[0038] The sealing component 6 is fixedly connected at its bottom end to the inner side of the mixing component 5 so that the sealing component 6 seals the mixing component 5.

[0039] In use, different types of raw materials are added to the inside of the proportioning component 2, and then the raw materials are transported to the inside of the mixing component 5, which is connected to the inside of the component, according to a certain ratio. Then, the drive component 3 is started to drive the transmission component 4 installed at the output end to operate. During the operation of the transmission component 4, the mixing component 5 installed inside is driven to operate, so that the mixing component 5 drives the different raw materials to mix. Since the mixing component 5 has multiple mixing chambers inside, the mixing time between different raw materials can be increased, which is more convenient.

[0040] This invention drives the transmission component 4 installed at the output end of the start-up drive component 3 to operate, so that the transmission component 4 drives the mixing component 5 installed inside to operate, so that the mixing component 5 mixes different raw materials. Since the mixing component 5 has multiple mixing chambers inside, it can increase the mixing time between different raw materials, thereby making the different raw materials fully mixed and improving the foaming quality.

[0041] In one embodiment, the proportioning component 2 includes a first proportioning container 201 and a second proportioning container 202. The bottom ends of the first proportioning container 201 and the second proportioning container 202 are fixedly installed to the top end of the mounting frame 1. A connecting pipe 203 is fixedly connected inside the first proportioning container 201 and the second proportioning container 202.

[0042] By adding different raw materials into the first mixing tank 201 and the second mixing tank 202 respectively, and then using a metering pump to extract the raw materials from the tanks according to a certain ratio, the extracted raw materials are transported to the inside of the connecting pipe 203. The metering pump is located inside the first mixing tank 201 and the second mixing tank 202, which facilitates the separate control of the conveying ratio of the two groups of raw materials.

[0043] In one embodiment, the drive assembly 3 includes a support frame 301, the bottom end of which is fixedly installed to the top end of the mounting frame 1, and a motor 302 is fixedly installed on the inner side of the support frame 301.

[0044] The support frame 301 is designed to support the motor 302 installed inside it, thereby ensuring the stability of the motor 302 during operation.

[0045] In one embodiment, the transmission component 4 includes a drive gear 401, the interior of which is fixedly installed with the output end of the motor 302, and the surface of the drive gear 401 is meshed with a driven gear 402.

[0046] The drive gear 401 installed at the output end is driven to rotate by starting the motor 302, so that the drive gear 401 drives the driven gear 402 to rotate. Since there are multiple sets of driven gears 402, and they are all meshed with the surface of the drive gear 401, when the drive gear 401 rotates, it can drive multiple sets of driven gears 402 to rotate.

[0047] In one embodiment, the mixing assembly 5 includes a lower housing 501, the bottom end of which is fixedly installed to the top end of the mounting bracket 1, and an upper housing 502 fixedly installed to the top end of the lower housing 501. A connecting shaft 503 is rotatably provided inside both the lower housing 501 and the upper housing 502. The outer surface of the connecting shaft 503 is fixedly installed inside the driven gear 402. The interiors of the lower housing 501 and the upper housing 502 are connected to the interior of the connecting pipe 203.

[0048] The mixing assembly 5 also includes a mixing ball 504. The interior of the mixing ball 504 is fixedly connected to the outer surface of the connecting shaft 503. The outer surface of the mixing ball 504 is in contact with the inner walls of the lower housing 501 and the upper housing 502. A mixing groove 505 is formed on the outer surface of the mixing ball 504.

[0049] When different proportions of raw materials enter the two sets of connecting pipes 203, they enter the cavity after the lower shell 501 and upper shell 502 are installed. At the same time, with the rotation of multiple sets of driven gears 402, they drive the internally installed connecting shaft 503 to rotate, so that the connecting shaft 503 drives the mixing ball 504 installed on the outer surface to rotate. Since the outer surface of the mixing ball 504 is in contact with the inner wall of the cavity after the lower shell 501 and upper shell 502 are installed, and the outer surface of the mixing ball 504 is provided with a mixing groove 505, the multiple sets of mixing balls 504 can divide the cavity. As the mixing ball 504 drives the mixing groove 505 to rotate, the raw materials entering the cavity can gradually enter the different cavities and be mixed inside the cavities. This increases the mixing time between the raw materials and ensures that the raw materials are fully mixed.

[0050] In one embodiment, the sealing assembly 6 includes a sealing groove 601, which is formed at the bottom end of the upper housing 502. A sealing strip 602 is sealed inside the sealing groove 601, and the bottom end of the sealing strip 602 is fixedly connected to the top end of the lower housing 501.

[0051] By covering the top of the lower housing 501 with the upper housing 502, the sealing groove 601 at the bottom of the upper housing 502 cooperates with the sealing strip 602 fixed at the top of the lower housing 501, thereby improving the sealing performance between the upper housing 502 and the lower housing 501, and facilitating the replacement or maintenance of the mixing ball 504 that is rotatably installed inside.

[0052] Through the above technical solution, 1. The drive component 3 drives the transmission component 4 installed at the output end to operate, so that the transmission component 4 drives the mixing component 5 installed inside to operate, so that the mixing component 5 drives different raw materials to mix. Since the mixing component 5 is equipped with multiple mixing chambers, the mixing time between different raw materials can be increased, thereby making the different raw materials fully mixed and improving the foaming quality.

[0053] 2. The driven gear 402 drives the internally mounted connecting shaft 503 to rotate, which in turn drives the mixing balls 504 mounted on the outer surface to rotate. Since the outer surface of the mixing balls 504 is in contact with the inner wall of the cavity after the lower housing 501 and the upper housing 502 are installed, and the outer surface of the mixing balls 504 is provided with mixing grooves 505, multiple sets of mixing balls 504 can divide the cavity. As the mixing balls 504 drive the mixing grooves 505 to rotate, the raw materials entering the cavity can gradually enter different cavities and be mixed inside the cavities. This increases the mixing time between the raw materials and ensures that the raw materials are fully mixed.
