Description

Technical Field

[0001] This utility model mainly relates to the field of polyurethane production equipment and devices, specifically to a polyurethane production device that facilitates material feeding. Background Technology

[0002] In the production process of polyurethane, a variety of raw materials need to be added, and the order in which they are added is often different. Moreover, some raw materials need to be added at specific stages of production. Existing polyurethane production equipment mostly uses closed tanks, which is not conducive to the addition of raw materials in the middle of the process.

[0003] In utility model patent application CN202323486697.1, published on August 23, 2024, entitled "A Polyurethane Production Device with Convenient Feeding," the device includes a tank, a hollow tube, a feeding pipe, a funnel, a motor, and a stirring rod. The tank has a cover plate on top, and the hollow tube extends vertically from above the cover plate into the tank. The motor is vertically mounted on the cover plate to drive the rotation of the hollow tube. A sealing plate is provided at the bottom of the hollow tube. The feeding pipe is symmetrically arranged at the bottom of the sealing plate and connected to the hollow tube, with its end pointing towards the inner wall of the tank. The funnel is located at the top of the hollow tube, and the stirring rod is mounted on the hollow tube and above the sealing plate. This device pours polyurethane raw materials into the hollow tube through the funnel, allowing them to flow through the hollow tube to the feeding pipe. The raw materials are then thrown out by the rotating feeding pipe and centrifugal force, improving the convenience of feeding and reducing residue problems.

[0004] However, in actual use, the production equipment involves various processes of mixing polyurethane raw materials, which requires manual feeding of the raw materials in sequence. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a polyurethane production device that facilitates material feeding, thereby solving the problem that in actual use, various polyurethane raw materials need to be stirred and mixed, which requires manual feeding of the raw materials in sequence.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a polyurethane production device for easy feeding, comprising a polyurethane production tank, a stirring motor installed at the bottom of the polyurethane production tank, a discharge window provided on one side surface of the polyurethane production tank, a support frame fixedly connected to the top surface of the polyurethane production tank, a side arm provided on one side surface of the support frame, a material distribution and feeding structure installed on the support frame and the side arm, and a servo motor provided on the surface of the support frame.

[0009] The material feeding structure includes a material dropping ring fixedly connected to the surface of the support frame, a material collecting cylinder fixedly connected below the material dropping ring, an outer fixing collar fixedly connected to the upper surface of the material dropping ring, a gear groove provided on one side surface of the outer fixing collar, a rotating outer gear disk movably connected to the inner surface of the outer fixing collar, a rotating feed port provided on the upper surface of the rotating outer gear disk, and a conical storage cylinder fixedly connected to one side surface of the side arm, with a cross partition provided on the inner wall surface of the conical storage cylinder.

[0010] Furthermore, the bottom of the inner wall of the polyurethane production tank is provided with stirring blades, and the stirring blades and stirring motor form a transmission structure. The top of the servo motor is provided with a transmission gear, and the rotating external gear disk meshes with the transmission gear to form a transmission.

[0011] Furthermore, the conical storage cylinder is mounted on the top surface of the rotating outer gear disk via a side arm and contacts the top of the rotating outer gear disk. The bottom of the conical storage cylinder is provided with several opening windows via a cross partition.

[0012] Furthermore, the rotating external gear disk forms a transmission structure with the transmission gear at the top of the servo motor through the gear slot, and forms a rotating structure on the inner wall surface of the outer fixed collar by the drive of the servo motor.

[0013] Furthermore, the rotating feed port at the top of the rotating outer gear disk rotates on the bottom surface of the conical storage cylinder, passes through several opening windows in sequence, and the other positions of the top of the rotating outer gear disk seal the bottom of the conical storage cylinder.

[0014] 3. Beneficial effects:

[0015] This utility model has a reasonable design. During the polyurethane production feeding operation, polyurethane raw materials are placed sequentially into the conical storage cylinder. Different polyurethane raw materials can be classified and placed through the cross partition. By starting the servo motor, the transmission gear above it drives the rotating outer gear disk inside the outer fixed collar to rotate. This causes the gear groove at the top of the rotating outer gear disk to move in the opening window below the storage cylinder. The rotating outer gear disk aligns with the opening window at the bottom of the conical storage cylinder through the rotating feed port above it. The raw materials inside the conical storage cylinder enter the rotating feed port and then fall into the polyurethane production tank through the dropping ring and the collecting cylinder. The continued rotation of the rotating outer gear disk aligns the rotating feed port above it with different opening windows to accommodate the feeding of different raw materials.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0026] See attached document Figure 1-4 The device includes a polyurethane production tank 1, a stirring motor 2 at the bottom of the polyurethane production tank 1, a discharge window 3 on one side surface of the polyurethane production tank 1, a support frame 4 fixedly connected to the top surface of the polyurethane production tank 1, a side arm 5 on one side surface of the support frame 4, a material feeding structure 6 installed on the surface of the support frame 4 and the side arm 5, and a servo motor 7 on the surface of the support frame 4. This device realizes the feeding of various materials through the material feeding structure 6.

[0027] The material feeding structure 6 includes a material dropping ring 601 fixedly connected to the surface of the support frame 4. A material collecting cylinder 602 is fixedly connected below the material dropping ring 601. An outer fixing sleeve 603 is fixedly connected to the upper surface of the material dropping ring 601. A gear groove 604 is provided on one side surface of the outer fixing sleeve 603. A rotating external gear disk 605 is movably connected to the inner surface of the outer fixing sleeve 603. A rotating feed inlet 606 is provided on the upper surface of the rotating external gear disk 605. A conical storage cylinder 607 is fixedly connected to one side surface of the side arm 5. A cross partition 608 is provided on the inner wall surface of the conical storage cylinder 607. An agitator blade is provided at the bottom of the inner wall of the polyurethane production tank 1, and the agitator blade and the agitator motor 2 form a transmission structure. A servo motor 7 is provided at its top. The transmission gear is connected to the rotating external gear disk 605 to form a transmission. The conical storage cylinder 607 is mounted on the top surface of the rotating external gear disk 605 via the side arm 5 and is in contact with the top of the rotating external gear disk 605. The bottom of the conical storage cylinder 607 is provided with several opening windows through the cross partition 608. The rotating external gear disk 605 forms a transmission structure with the transmission gear at the top of the servo motor 7 through the gear slot 604. It also forms a rotation structure on the inner wall surface of the outer fixed collar 603 driven by the servo motor 7. The rotating feed port 606 at the top of the rotating external gear disk 605 rotates on the bottom surface of the conical storage cylinder 607 and passes through several opening windows in sequence. Other positions at the top of the rotating external gear disk 605 block the bottom of the conical storage cylinder 607.

[0028] In this embodiment, during the polyurethane production feeding operation, polyurethane raw materials are sequentially placed inside the conical storage cylinder 607. Different polyurethane raw materials can be classified and placed through the cross partition 608. By starting the servo motor 7, the transmission gear above it drives the rotating outer gear disk 605 inside the outer fixed collar 603 to rotate. This causes the gear slot 604 at the top of the rotating outer gear disk 605 to move at the opening window below the storage cylinder 607. This allows the rotating outer gear disk 605 to align with the opening window at the lower end of the conical storage cylinder 607 through the rotating feed port 606 above it. The raw materials inside the conical storage cylinder 607 enter the rotating feed port 606 and then fall into the polyurethane production tank 1 through the dropping ring 601 and the collecting cylinder 602. The continued rotation of the rotating outer gear disk 605 allows the rotating feed port 606 above it to connect with different opening windows to accommodate the feeding of different raw materials.

[0029] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
