Description

Technical Field

[0001] This utility model relates to the field of polyurethane production technology, specifically to a mixing device with a quantitative proportioning structure. Background Technology

[0002] In fields such as chemical raw material synthesis, food ingredient processing, and pharmaceutical preparation production, the precise proportions of various materials directly affect product performance and quality stability.

[0003] A mixing device with a quantitative proportioning structure typically consists of a storage silo, a high-precision metering unit, a dynamic mixing chamber, a conveying pipeline, and an intelligent control system. The storage silo stores different types of materials and is equipped with a stirring device to prevent material agglomeration. The high-precision metering unit uses equipment such as a screw metering pump, loss-in-weight scale, or mass flow meter to accurately control the material delivery rate according to a preset formula, with a metering accuracy of ±0.5%. The dynamic mixing chamber is equipped with specially structured stirring blades or static mixing elements to achieve rapid and uniform mixing of materials through high-speed rotation or strong turbulence. The conveying pipeline connects all components to achieve stable material transmission. The intelligent control system integrates a PLC controller and a touch screen operating interface, which can preset parameters such as material proportions and mixing time, and monitor the operating status of each stage in real time.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional mixing devices mostly use single-shaft stirring paddles or simple rotary stirring, and the material only moves in one direction, making it difficult to achieve all-round and deep mixing, resulting in low mixing uniformity. Especially for materials with high viscosity or complex proportions, the mixing effect is even less ideal. In view of this, we propose a mixing device with a quantitative proportioning structure.

[0005] The purpose of this invention is to provide a mixing device with a quantitative proportioning structure to solve the problems mentioned in the background art.

[0017] Compared with the prior art, the present invention provides a mixing device with a quantitative proportioning structure, which has the following beneficial effects:

[0018] 1. This mixing device with a quantitative proportioning structure, in order to improve the mixing uniformity of materials, is equipped with a stirring component. This component, in conjunction with a hydraulic device, drives the connecting frame to move the circular frame up and down, so that the limiting disc and the flat paddle are close to the material liquid surface. The servo motor drives the stirring rod, and the propeller forms an upward flow in the center of the material tank. The hydraulic device drives the flat paddle to generate radial shear force below the limiting disc. The two work together to improve the mixing uniformity of materials. At the same time, the extrusion frame and the spring in the cylinder provide pre-tightening force for the lid, and maintain the seal through elastic compensation.

[0019] 2. This mixing device with a quantitative proportioning structure is equipped with an auxiliary component to enable automated positioning and rapid switching of material containers. This component works with an asynchronous motor to drive a threaded rod to rotate, and the threaded transmission causes the slide plate to move linearly along the chute. At the same time, multiple straight rods slide and guide within the limiting groove to prevent the slide plate from deviating. When it is necessary to change the material container, the threaded rod reverses to move the slide plate out. The self-locking design of the threaded groove and the threaded rod ensures that there is no slippage when fully loaded. Combined with the rigid support of the chute, the device remains stable during high-speed mixing. Attached Figure Description

[0032] Please see Figures 1-6 This utility model provides a technical solution:

[0033] A mixing device with a quantitative proportioning structure includes a base plate 1, a groove 2 on the base plate 1, and a support frame 3 fixedly installed on the base plate 1.

[0034] In one embodiment of this utility model, a stirring assembly 4 is provided on the support frame 3. The stirring assembly 4 includes a sliding plate 41, which is slidably mounted on the base plate 1. A material bucket 42 is snapped onto the sliding plate 41. A hydraulic device 43 is fixedly mounted on the support frame 3. A connecting frame 44 is fixedly mounted on the piston end of the hydraulic device 43. One end of a mounting frame 45 is fixedly mounted on the connecting frame 44. A circular frame 46 is fixedly mounted on the other end of the mounting frame 45. A servo motor 47 is fixedly mounted on the circular frame 46. An extrusion frame 48 is fixedly mounted on the circular frame 46. A cylinder 49 is fixedly mounted at the bottom of the extrusion frame 48. One end of a spring 410 is fixedly mounted at the bottom of the extrusion frame 48. One end of a circular rod 411 is fixedly mounted at the other end of the spring 410. A cover 412 is fixedly mounted at the other end of the circular rod 411. One end of a stirring rod 413 is fixedly mounted at the output end of the servo motor 47. One end of a limit rod 414 is fixedly mounted at the bottom of the circular frame 46. A propeller 415 is fixedly installed at the other end of 413, and a limiting disc 416 is fixedly installed at the other end of the limiting rod 414. A flat paddle 417 is fixedly installed on the limiting disc 416. Multiple sets of hydraulic devices 43, mounting frames 45, extrusion frames 48, cylinders 49, springs 410, round rods 411, limiting rods 414, and flat paddles 417 are provided. Hydraulic devices 43, connecting frames 44, mounting frames 45, round frames 46, servo motors 47, and extrusion frames 48 are also provided. A cylinder 49, a spring 410, a round rod 411, a cover 412, a stirring rod 413, a limiting rod 414, a propeller 415, a limiting disc 416, and a flat paddle 417 are arranged above the material bucket 42. The spring 410 is arranged inside the cylinder 49. The round rod 411 slides inside the cylinder 49. The stirring rod 413 and the limiting rod 414 pass through the cover 412. The propeller 415, the limiting disc 416, and the flat paddle 417 are arranged below the cover 412.

[0035] In this embodiment, firstly, the material bucket 42 containing the material is snapped onto the sliding plate 41 and moves with the sliding plate 41. Next, the hydraulic device 43 is activated, which drives the connecting frame 44 to lower the circular frame 46, causing the limiting disc 416 and the flat paddle 417 to enter the material bucket 42. At the same time, the spring 410 is compressed inside the cylinder 49, providing pre-tightening force to the lid 412, so that the lid 412 tightly covers the material bucket 42. Simultaneously, after the servo motor 47 is started, it drives the stirring rod 413 to rotate, and the propeller 415 at the end of the stirring rod 413 moves inside the material bucket 42. During mixing, the limiting rod 414 passes through the cover 412, and the limiting disc 416 at its end fixes the flat paddle 417. The hydraulic device 43 controls the lifting and lowering of the circular frame 46, so that the flat paddle 417 generates radial shear force below the limiting disc 416. This works in conjunction with the upward flow formed by the propeller 415 to improve the mixing uniformity of the material. At the same time, the spring 410 is compressed inside the cylinder 49 to provide pre-tightening force for the cover 412, so that the cover 412 tightly covers the material bucket 42. After mixing is completed, the hydraulic device 43 is activated again to lift the circular frame 46 and related components.

[0036] In one embodiment of this utility model, an auxiliary component 5 is provided on the base plate 1. The auxiliary component 5 includes a straight rod 51. The straight rod 51 is fixedly installed on the base plate 1. A limit groove 52 is opened on the slide plate 41. An asynchronous motor 53 is fixedly installed on the base plate 1. A threaded rod 54 is fixedly installed at the output end of the asynchronous motor 53. A threaded groove 55 is opened on the slide plate 41. Multiple sets of straight rods 51 and limit grooves 52 are provided. Multiple sets of straight rods 51 slide inside the limit grooves 52. The threaded rods 54 are threadedly installed inside the threaded grooves 55. The slide plate 41 slides inside the slide groove 2.

[0037] In this embodiment, the straight rod 51 fixed on the base plate 1 cooperates with the limiting groove 52 opened on the slide plate 41 to play a guiding role, ensuring that the slide plate 41 will not deviate during movement. When the asynchronous motor 53 starts, it drives the threaded rod 54 to rotate, and through the threaded transmission, the slide plate 41 moves linearly along the slide groove 2 of the base plate 1. When it is necessary to replace the material bucket 42, the asynchronous motor 53 reverses and the threaded rod 54 rotates in the opposite direction, so that the slide plate 41 moves out of the working position. The self-locking design of the threaded groove 55 and the threaded rod 54 can ensure that the slide plate 41 will not slip when the material bucket 42 is fully loaded. Combined with the rigid support of the slide groove 2, it ensures the stability of the device during high-speed stirring.

The PLC controller is a conventional and known device that can control the hydraulic device 43, servo motor 47, and asynchronous motor 53.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
