Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating processing technology, and in particular to a dispersion device for fire-retardant coating processing. Background Technology

[0002] Fire-retardant coatings are applied to the surface of materials to improve their fire resistance, slow the spread of flames, or prevent combustion for a certain period of time. During the production and processing of fire-retardant coatings, to achieve better coloring results, the coloring and extender materials need to be thoroughly mixed and dispersed. Therefore, a dispersing device is used to shear and impact the fire-retardant coating materials in the container, achieving the purpose of refining, dispersing, and dissolving the materials.

[0003] Chinese Patent Publication No. CN219647220U discloses a coating dispersion device. The coating dispersion device includes a lifting mechanism comprising a lifting platform and a first motor. A second motor is fixedly installed on the lifting platform. The output end of the second motor rotates through the lifting platform and is fixedly connected to a stirring shaft. A stirring head is fixedly connected to the bottom end of the stirring shaft. A cover plate is sleeved on the outside of the stirring shaft. A shaft sleeve adapted to the stirring shaft is fixedly connected through the middle of the cover plate. A spring is fixedly connected to the top surface of the shaft sleeve, and one end of the spring is fixedly installed to the bottom surface of the lifting platform.

[0004] While the aforementioned device can hold the cover plate against the paint bucket during use, preventing paint from spilling due to centrifugal force during paint dispersion, the mixing shaft and head, after mixing the paint inside the bucket, require the use of a threaded rod and lifting platform to move them upwards for easy removal. During this process, paint adhering to the surface of the mixing shaft and head drips onto the ground, easily leading to paint waste and reducing the device's practicality, thus failing to meet user needs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dispersion device for processing fire-retardant coatings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dispersion device for processing fire-retardant coatings includes a base, a container placed on top of the base, two telescopic cylinders mounted on the top of the base, the telescopic ends of the two cylinders being connected to a top plate, a stirring mechanism for dispersing the fire-retardant coating inside the container being installed inside the top plate, and a shielding mechanism for shielding the stirring mechanism being provided at the bottom of the top plate. The shielding mechanism includes a retractable shielding cover installed at the bottom of the top plate, a counterweight plate installed at the bottom of the shielding cover, and a drive mechanism for controlling the automatic extension and retraction of the shielding cover being installed above the counterweight plate.

[0008] Preferably, the stirring mechanism includes a drive motor, a mounting plate is installed at the bottom of the drive motor, the mounting plate is threaded to the top of the top plate by multiple bolts, and the output end of the drive motor passes through the top plate and is connected to a rotating shaft.

[0009] Preferably, the bottom end of the rotating shaft passes downward from the center of the shield, and multiple stirring blades are installed at the bottom end of the rotating shaft.

[0010] Preferably, the radius of the shield is greater than the length of the multiple stirring blades, and the shield is made of TPU material.

[0011] Preferably, the drive mechanism includes multiple winding wheels, all of which are rotatably mounted on the top of the top plate, and the outer walls of the multiple winding wheels are wound with pull ropes.

[0012] Preferably, the top plate has multiple circular holes for the pull ropes to pass through downwards, and the ends of the multiple pull ropes away from the winding wheel pass through the corresponding circular holes and are connected to the counterweight plate.

[0013] Preferably, two baffles are provided below the counterweight plate, and two grooves are opened at the bottom of the counterweight plate. Two sliders are installed inside each groove, and the top of the two counterweight plates are respectively connected to the bottom of the two sliders.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, after the raw materials inside the container are dispersed, the device controls multiple winding wheels to rotate synchronously while waiting for the container to be placed back on the base. This causes multiple pull ropes to unfold downwards, pulling the counterweight plate downwards to below the stirring blades. Two baffles then block the area below the counterweight plate, allowing the raw materials on the rotating shaft and the surfaces of the stirring blades to drip onto the tops of the baffles, preventing waste caused by direct downward dripping. After the container is placed back on the base, the two baffles are moved away from each other and opened. The tops of the baffles rub against the inner wall of the counterweight plate, scraping the raw materials adhering to the tops of the baffles into the container, preventing waste of this material. This improves the practicality of the device in actual use, enabling it to meet user needs.

[0016] 2. In this utility model, as the counterweight plate moves downward, it can drive the shield to extend downward and completely cover the surface of the rotating shaft and multiple stirring blades, thus avoiding the problem of excessive contact between the small amount of raw material attached to the surface of the rotating shaft and multiple stirring blades and the outside air, resulting in a faster drying speed.

[0017] 3. In this utility model, when the stirring mechanism stirs and disperses the raw materials inside the container, the two baffles come into contact with the top of the container. At this time, the two baffles at the top of the container can be used as cover plates to shield the fireproof coating raw materials that are being stirred and dispersed inside the container, preventing a small amount of raw materials from splashing out from the top opening of the container, reducing waste of raw materials during the dispersion process, and also protecting the surrounding workers.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6 A dispersion device for processing fire-retardant coatings includes a base 1, a container 4 placed on top of the base 1, two telescopic cylinders 2 installed on the top of the base 1, the telescopic ends of the two telescopic cylinders 2 being connected to a top plate 3, a stirring mechanism for dispersing the fire-retardant coating inside the container 4 installed inside the top plate 3, and a shielding mechanism for shielding the stirring mechanism provided at the bottom of the top plate 3. The shielding mechanism includes a retractable shielding cover 6 installed at the bottom of the top plate 3, a counterweight plate 7 installed at the bottom of the shielding cover 6, and a drive mechanism for controlling the automatic extension and retraction of the shielding cover 6 installed above the counterweight plate 7.

[0027] As a technical optimization of this utility model, the stirring mechanism includes a drive motor 5, and a mounting plate 10 is installed at the bottom of the drive motor 5. The mounting plate 10 is threadedly connected to the top of the top plate 3 by multiple bolts 13. The output end of the drive motor 5 passes through the top plate 3 and is connected to a rotating shaft 14. After the drive motor 5 is started, it can drive the rotating shaft 14 to rotate together at the bottom of the top plate 3.

[0028] As a technical optimization of this utility model, the bottom end of the rotating shaft 14 passes downward from the center of the shield 6, and multiple stirring blades 11 are installed at the bottom end of the rotating shaft 14. During the rotation of the rotating shaft 14, it can drive the multiple stirring blades 11 to rotate synchronously, so as to mix, stir and disperse the coloring raw materials and body raw materials inside the container 4.

[0029] As a technical optimization in this utility model, the radius of the shield 6 is greater than the length of the multiple stirring blades 11, and the shield 6 is made of TPU material. Because the radius of the shield 6 is greater than the length of the multiple stirring blades 11, it can cover the surface of the multiple stirring blades 11 after extending downwards, providing a shielding and protective effect for the rotating shaft 14 and the multiple stirring blades 11. The shield 6 uses TPU, or thermoplastic polyurethane, a high-performance environmentally friendly material with excellent high tensile strength, high tensile strength, toughness, and aging resistance. The paint film made of this material can be used for up to 5 years or more, ensuring the shield 6 can be used for a long time. These characteristics enable the TPU shield 6 to effectively prevent paint adhesion during use, protecting the paint surface from damage.

[0030] As a technical optimization of this utility model, the drive mechanism includes multiple winding wheels 9, all of which are rotatably mounted on the top of the top plate 3. Each winding wheel 9 has a pull rope 12 wound around its outer wall. In actual use, multiple drive devices are pre-installed on the top of the top plate 3. The output ends of these drive devices are connected to the rotating parts of the multiple winding wheels 9, thereby enabling the multiple winding wheels 9 to automatically wind and unwind the multiple pull ropes 12 downwards.

[0031] As a technical optimization of this utility model, the top plate 3 has multiple circular holes for the pull ropes 12 to pass through downwards. The ends of the multiple pull ropes 12 away from the winding wheels 9 pass through the corresponding circular holes and connect to the counterweight plate 7. During the winding process of the multiple winding wheels 9, the counterweight plate 7 can be driven to move upwards below the top plate 3, so that the unfolded shield 6 retracts upwards synchronously; and during the unfolding process of the multiple winding wheels 9, the counterweight plate 7 can be driven to move downwards below the top plate 3, so that the retracted shield 6 unfolds downwards synchronously and covers the surface of the rotating shaft 14 and the multiple stirring blades 11.

[0032] As a technical optimization of this utility model, two baffle plates 8 are provided below the counterweight plate 7, and two sliding grooves 15 are opened at the bottom of the counterweight plate 7. Two sliders 16 are installed inside each of the two sliding grooves 15, and the top ends of the two counterweight plates 7 are respectively connected to the bottom ends of the two sliders 16. Double-ended lead screws are preset inside the two sliding grooves 15, and two driving devices are preset inside the counterweight plate 7. The output ends of the two driving devices are respectively connected to one end of the two double-ended lead screws, thereby driving the two double-ended lead screws to rotate inside the corresponding sliding grooves 15, driving the two sliders 16 to move towards or away from each other inside the sliding grooves 15, and thus driving the two baffle plates 8 to move and adjust together below the counterweight plate 7.

[0033] In this invention, the telescopic ends of the two telescopic cylinders 2 are first controlled to extend upwards together, driving the top plate 3 and the stirring mechanism to move upwards to a position higher than the container 4. Then, the container 4 is placed on top of the base 1, and the fireproof coating material to be dispersed is poured into the container 4. Finally, the telescopic ends of the two telescopic cylinders 2 are controlled to retract downwards to return to their original positions, thereby driving multiple stirring blades 11 and the rotating shaft 14 into the container 4. The drive motor 5 is started to drive the rotating shaft 14 and multiple stirring blades 11 to rotate inside the container 4, stirring and dispersing the fireproof coating material inside the container 4.

[0034] At this time, the multiple winding wheels 9 of the drive mechanism can be controlled to rotate. With the help of the weight of the counterweight plate 7, multiple pull ropes 12 can be driven to unfold downwards, so that the two shielding plates 8 set below the counterweight plate 7 can come into contact with the top of the container 4. At this time, the two shielding plates 8 located on the top of the container 4 can be used as cover plates to shield the fireproof coating raw materials that are being stirred and dispersed inside the container 4, preventing a small amount of raw materials from splashing out from the top opening of the container 4, reducing the waste of raw materials during the dispersion process, and also protecting the surrounding personnel.

[0035] After the raw material dispersion work inside container 4 is completed, the two baffles 8 can be moved away from each other, so that the small amount of raw material attached to the bottom of the two baffles 8 can be automatically scraped off into the inside of container 4 during the movement, avoiding waste of this part of the raw material; then the telescopic ends of the two telescopic cylinders 2 are extended upward again, driving the top plate 3 and the stirring mechanism to move upward from the inside of container 4, so that container 4 can be taken off the top of base 1. After the dispersed raw material inside container 4 is discharged, container 4 is placed back on the top of base 1 for further dispersion of the subsequent fireproof coating.

[0036] While the device is waiting for container 4 to be placed back into the gap of base 1, the raw material adhering to the surface of the rotating shaft 14 and multiple stirring blades 11 will drip down onto the top of base 1, causing contamination of the top of base 1 and waste of raw material. After the extension ends of the two telescopic cylinders 2 are extended, the stirring mechanism is moved upward to above container 4. Then, multiple winding wheels 9 are controlled to rotate synchronously, causing multiple pull ropes 12 to unfold downward. With the help of the downward movement of the counterweight plate 7, the shield 6 is extended downward and completely covers the surface of the rotating shaft 14 and multiple stirring blades 11. This prevents the small amount of raw material adhering to the surface of the rotating shaft 14 and multiple stirring blades 11 from having too much contact with the outside air, thus avoiding the problem of excessive drying speed.

[0037] At this time, the counterweight plate 7 is located below the multiple stirring blades 11. The two baffle plates 8 are controlled to move towards each other and come into close contact, blocking the area below the counterweight plate 7. This allows the raw materials on the surface of the rotating shaft 14 and the multiple stirring blades 11 to drip onto the top of the two baffle plates 8, preventing the raw materials from dripping directly down to the top of the base 1.

[0038] After the container 4 is placed back on top of the base 1, the two baffles 8 are controlled to move and open in opposite directions. The tops of the two baffles 8 can rub against the inner wall of the counterweight plate 7 and scrape the raw material attached to the tops of the two baffles 8 into the interior of the container 4, thus avoiding waste caused by the raw material that falls on the tops of the baffles 8.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
