Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, and in particular to a mixing device for natural latex nanocomposite materials. Background Technology

[0002] With the continuous development of materials science, natural latex nanocomposites have been widely used in many industries, such as medical supplies, aerospace, and high-end electronics, due to their excellent properties, such as high strength, high elasticity, good wear resistance, and antibacterial properties. However, achieving uniform mixing of natural latex and nanomaterials has always been a challenge in the preparation of these composites, and existing mixing technologies have many shortcomings.

[0003] Poor mixing uniformity: Traditional mixing equipment has a relatively simple mixing structure and a single type of stirring rod. During the mixing process, it is difficult for natural latex and nanomaterials to fully contact and disperse evenly. Nanomaterials are prone to agglomeration, resulting in uneven distribution of components within the mixed composite material, affecting the stability and consistency of material properties. For example, in the production of high-performance rubber products, uneven dispersion of nanomaterials can lead to insufficient local strength in the product, making it prone to cracking during use.

[0004] Low mixing efficiency: Common mixing devices have limited stirring speeds and cannot fully cover the entire mixing space. Mixing large quantities of materials requires a long time, which not only increases production costs but also reduces production efficiency. With rapidly growing market demand, low mixing efficiency makes it difficult to meet the production scale requirements of enterprises.

[0005] Inconvenient equipment maintenance: Some mixing equipment has a complex structure and numerous parts. After long-term use, the stirring components are prone to wear and tear, and repair and replacement are difficult. Cleaning the equipment is also troublesome, and residual materials may affect the quality of the next mixing, increasing equipment maintenance costs and downtime.

[0006] These problems severely restrict the development and application of natural latex nanocomposites. Therefore, it is urgent to develop a new type of natural latex nanocomposite mixing device to address the shortcomings of existing technologies, improve mixing quality and efficiency, and meet diverse production needs. Utility Model Content

[0007] The purpose of this invention is to provide a mixing device for natural latex nanocomposite materials in order to solve the above-mentioned problems.

[0008] To address the aforementioned problems, this utility model provides a technical solution: a natural latex nanocomposite material mixing device, comprising a mixing chamber, a discharge pipe, a valve plate, a vertical rod, a top plate, a feed nozzle, a cover, an opening, a first motor, a slot, a lifting plate, a lead screw, a bearing seat, a pulley mounting plate, a pulley, a second motor, a mounting base, a rotating shaft, a stirring rod, and a locking assembly; the lower surface of the mixing chamber is fixedly connected to both sides of the discharge pipe, and a valve plate is provided in each discharge pipe; a vertical rod is fixedly connected to the center of the bottom surface of the mixing chamber; a top plate is provided on the top of the mixing chamber; feed nozzles for feeding are provided on both sides of the top plate; a locking assembly is provided between the mixing chamber and both sides of the top plate; a cover is fixedly connected to the top of the top plate, and an opening is provided at the center of the top of the cover; slots are provided on both sides of the chamber walls inside the cover chamber; the upper left side of the cover chamber... A first motor is fixedly connected. A bearing seat is fixedly connected to the lower left side of the chamber of the cover. A lead screw is fixedly connected to the output end of the first motor, and the end of the lead screw is movably connected to the bearing seat. The left side of the lifting plate is slidably connected to a slot on the left side. The lifting plate is threadedly connected to the lead screw. A pulley mounting plate is fixedly connected to the right side of the lifting plate. Several pulleys are connected to the right side of the pulley mounting plate, and the pulleys are slidably connected to the slot on the right side. A second motor is fixedly connected to the center of the upper surface of the lifting plate. A mounting base is fixedly connected to the center of the lower surface of the lifting plate. A rotating shaft is movably connected to the top plate. The end of the rotating shaft is slidably connected to a vertical rod, and the top of the rotating shaft is movably connected to the mounting base through a bearing. The rotating shaft is also fixedly connected to the output end of the second motor. Several stirring rods are fixedly connected to the rotating shaft.

[0009] Preferably, the locking assembly comprises a flange, a cavity, a slide rail, a bearing, a screw, a handwheel, and a locking rod; both sides of the mixing chamber are integrally formed with flanges; both sides of the top plate are provided with cavities; the upper end of the cavity is fixedly connected to the slide rail; a screw is movably connected in the cavity, the inner end of the screw is movably connected to the inner end of the cavity through a bearing, and a handwheel is fixedly connected to the outer end of the screw; a locking rod is threadedly connected to the screw, the lower end of the locking rod is engaged in the flange, and the upper end of the locking rod is slidably connected to the slide rail.

[0010] Preferably, the handwheel is provided with anti-slip texture.

[0011] Preferably, the slide rail is coated with grease.

[0012] Preferably, the mixing chamber is inverted taper-shaped.

[0013] Preferably, the feed nozzle is inclined.

[0014] The beneficial effects of this utility model are as follows: (1) Excellent mixing effect: The first motor drives the lead screw to move the lifting plate up and down along the slot, while the second motor drives the rotating shaft and stirring rod to rotate. This unique structural design allows the stirring rod to stir the material at different heights, covering the mixing chamber in all directions, effectively avoiding local accumulation of materials, greatly reducing the agglomeration of nanomaterials, ensuring that natural latex and nanomaterials are fully contacted and evenly dispersed, thereby improving the uniformity of the internal component distribution of the composite material, stabilizing and improving the material performance. For example, in the preparation of high-end medical latex products, it can ensure that the performance of each part of the product is consistent and avoid quality problems caused by uneven materials; the mixing chamber is inverted conical, which is conducive to the material flowing downward naturally during the stirring process, and with the movement of the stirring rod, a more reasonable material flow path is formed, further promoting the uniform mixing of materials.

[0015] (2) High mixing efficiency: The second motor can flexibly adjust the stirring speed according to the material characteristics and mixing requirements to achieve rapid mixing and shorten the mixing time. For large-scale production, it can effectively increase the output per unit time and reduce production costs; the lifting plate drives the stirring rod to move up and down, so that the stirring range covers the entire mixing chamber space. Compared with traditional stirring equipment, the stirring range is larger, which can process a large amount of materials more efficiently and meet the growing production scale needs of enterprises.

[0016] (3) Convenient equipment maintenance: The overall structure is reasonably simple and has fewer parts compared to some complex traditional mixing equipment, which reduces the probability of failure. Moreover, the installation method of the stirring parts is easy to disassemble and replace. When wear occurs, maintenance personnel can quickly carry out maintenance and replacement operations, reducing downtime. The inverted conical design of the mixing chamber makes it easier to discharge residual materials during cleaning. Combined with the openable top plate (achieved through locking components), it is convenient for operators to thoroughly clean the inside of the mixing chamber, avoiding residual materials from affecting the next mixing quality and reducing maintenance costs.

[0017] (4) Easy to operate and install: The control method of manual start and stop switch is intuitive and easy to understand. No complicated operation training is required. Ordinary staff can master it and reduce the skill threshold of operators. The connection method of each component is reasonably designed. For example, the locking component fixes the top plate and the mixing chamber by rotating the screw through the handwheel. The installation process is simple and quick, which can save installation time and labor costs.

[0018] (5) Humanized design details: The handwheel is equipped with anti-slip texture, which increases the friction between the operator's hand and the handwheel when turning the handwheel, preventing the hand from slipping during operation and improving the safety and convenience of operation; the slide rail is coated with grease, which reduces the friction when the locking rod slides on the slide rail, making the operation smoother, and also reducing the wear of parts and extending the service life of the equipment.

[0028] like Figures 1 to 4 As shown, the locking assembly has the following specific structure: a flange 4, a cavity 8, a slide rail 9, a bearing 10, a screw 11, a handwheel 12, and a locking rod 13. Both sides of the mixing chamber 1 are integrally formed with flanges 4. Both sides of the top plate 6 are provided with cavities 8. The upper end of the cavity 8 is fixedly connected to the slide rail 9. The screw 11 is movably connected to the cavity 8, with its inner end movably connected to the inner end of the cavity 8 via a bearing 10.

[0029] The handwheel 12 has anti-slip texture; the slide rail 9 is coated with grease; the mixing chamber 1 is inverted conical; and the feed nozzle 7 is inclined.

[0030] The usage status of this utility model is as follows:

[0031] (1) Preparation stage: The mixing chamber 1 and the top plate 6 are fixed by a locking assembly. The specific operation is to rotate the handwheel 12 to drive the screw 11 to rotate, so that the lower end of the locking rod 13 is engaged in the flanges 4 on both sides of the mixing chamber 1. After the installation is completed, check whether the connection of each component is firm, whether the valve plate 3 of the discharge pipe 2 is closed, and whether the wiring of the first motor 16, the second motor 23 and other electrical components is correct. Open the feed nozzles 7 on both sides of the top plate 6 and pour the natural latex and nanomaterials into the mixing chamber 1 from the inclined feed nozzles 7 in a certain proportion. The inclined feed nozzles 7 are designed to facilitate the rapid and smooth entry of materials into the mixing chamber 1 and reduce material residue.

[0032] (2) Mixing stage: The first motor 16 is started, and its output end drives the lead screw 19 to rotate. Since the lifting plate 18 is connected to the lead screw 19 by a thread, and the left side slides in the slot 17 while the right pulley 22 slides in the right slot 17, the lifting plate 18 will move up and down along the slot 17. At the same time, the second motor 23 is started, and its output end drives the rotating shaft 25 to rotate, which in turn causes the stirring rod 26 fixed on the rotating shaft 25 to rotate at high speed. During the up and down movement and rotation of the stirring rod 26, the natural latex and nanomaterials in the mixing chamber 1 are stirred in all directions to ensure that the materials are fully contacted and mixed evenly. The mixing chamber 1 is inverted conical in shape, which helps the materials to flow downward naturally during stirring. This shape works in conjunction with the movement of the stirring rod 26 to further promote the mixing of materials, reduce material agglomeration, and improve the mixing quality.

[0033] (3) Discharge stage: After mixing is completed, turn off the first motor 16 and the second motor 23. Open the valve plate 3 in the discharge pipe 2. Under the action of gravity, the mixed natural latex nanocomposite material flows out from the discharge pipes 2 on both sides of the lower surface of the mixing chamber 1 and enters the subsequent processing stage.
