Technical Field
[0001] The utility model relates to the technical field of the production of amidine ultraviolet absorbers, in particular to a production device for amidine ultraviolet absorbers. Background Technique
[0002] In order to extend the service life of polymer materials, almost all polymer materials need to be added with anti-aging additives during the processing process. Ultraviolet absorbers are an important type of polymer anti-aging additives. Currently, there are mainly benzotriazole ultraviolet absorbers, such as UV326, UV328, UV329, UV234, UV360, etc., benzophenone ultraviolet absorbers, such as UV0, UV9, UV531, etc., triazine ultraviolet absorbers, such as UV1577, UV1164, UV400, etc., benzoate ultraviolet absorbers, such as UV120, UV2908, etc. Each type of the above ultraviolet absorbers has its own unique absorption spectrum and application performance, and plays an important role in different fields.
[0003] In the existing production equipment for amidine ultraviolet absorbers, there is a washing, filtering and vacuum triple-in-one dryer. In this equipment, raw materials can be mixed, extracted and dried. During the heating process, the raw materials are heated by a heating jacket and a heating stirrer. However, the existing heating stirrers generally have a smooth surface, resulting in low heat transfer efficiency. And when using heat sinks, there is also the problem that the gaps of the heat sinks are difficult to clean. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a production device for amidine ultraviolet absorbers to solve the technical problem that the gaps of the heat sinks are difficult to clean.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A production device for amidine ultraviolet absorbers, including a housing, a power device, a stirring rod, a spiral stirring blade, and a scraping mechanism. There is a receiving cavity inside the housing. The power device is arranged on the housing. The stirring rod is arranged in the receiving cavity. One end of the stirring rod is in power connection with the power device. A connecting rod is arranged on the outer peripheral wall of the stirring rod. The spiral stirring blade is arranged in the receiving cavity. The spiral stirring blade is connected to the connecting rod and is arranged around the stirring rod. Heat sinks are arranged on the surface of the spiral stirring blade. Heat dissipation grooves are opened on the heat sinks. The scraping mechanism is slidably arranged on the heat sinks. The scraping mechanism includes a sliding frame and a resistance plate. The sliding frame is sleeved on the heat sinks. The sliding frame is provided with scraping blades adapted to the heat dissipation grooves. When the sliding frame moves along the extending path of the heat sinks, the scraping blades slide in the heat dissipation grooves. The resistance plate is arranged at one end of the sliding frame away from the heat sinks and is used to generate a pressing force on the sliding frame under the action of the flowing material during stirring.
[0006] By adopting the above technical solutions, the heat sink and the heat dissipation grooves thereon increase the heat dissipation area, effectively improving the heat transfer efficiency, making the heating process more efficient, increasing the efficiency of the device, and the sliding frame enables the scraping blade to slide stably in the heat dissipation grooves, achieving...

[0009] Further, one side of at least one resistance plate is rotatably connected with an extension plate through a torsion rotating shaft.
[0010] By adopting the above technical solutions, the connection between the extension plate and the resistance plate through the torsion rotating shaft enables the position of the extension plate to be conveniently adjusted when needed, thereby increasing the pressing force generated by the resistance plate on the sliding frame and improving the cleaning effect of the scraping blade.
[0011] Further, a push rod is provided on the extension plate.
[0012] By adopting the above technical solutions, through the push rod, the position of the extension plate can be conveniently adjusted when needed, thereby changing the pressing force generated by the resistance plate on the sliding frame.
[0013] Further, a clamping hole is formed on the resistance plate, the push rod is arranged on the surface of the extension plate facing the resistance plate, and the push rod is adapted to the clamping hole.
[0014] By adopting the above technical solutions, the clamping hole provides a fixed clamping point for the push rod, enabling the extension plate to remain stable when retracted.
[0015] Further, retaining plates are fixedly connected to both ends of the extending path of the heat sink.
[0016] By adopting the above technical solutions, the retaining plates effectively prevent the scraping mechanism from possibly disengaging from the heat sink during the stirring process, ensuring that the scraping mechanism can work properly when cleaning is required and ensuring the smooth progress of production.
[0017] Further, there are multiple heat dissipation grooves and the scraping blades, and the multiple heat dissipation grooves and scraping blades are arranged linearly and equidistantly.
[0018] By adopting the above technical solutions, the linear equidistant arrangement of the multiple heat dissipation grooves increases the heat dissipation area, improves the heat transfer efficiency, and enables the device to be more efficient during the heating process.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0030] The following will describe the embodiments of the present utility model according to its overall structure.
[0031] Embodiment 1:
[0032] A production device for amidine ultraviolet absorbers, as Figures 1-4 shown, includes a housing 1. A power device 2 is fixedly connected to the top of the housing 1. The power device 2 can adopt devices such as a rotary motor and a pump. The output end of the power device 2 is fixedly connected to a stirring rod 3. The stirring rod 3 is fixedly connected to a spiral stirring blade 5 through a connecting rod 4. Radiating fins 6 are fixedly connected to both the upper and lower surfaces of the spiral stirring blade 5. Heat dissipation grooves 601 are formed in the radiating fins 6. The radiating fins 6 and the heat dissipation grooves 601 thereon increase the heat dissipation area, effectively improving the heat transfer efficiency, making the heating process more efficient, increasing the efficiency of the device. At the same time, the spiral stirring blade 5 realizes the full mixing and stirring of raw materials, improving the production efficiency and product quality.
[0033] Refer to Figure 2 , both ends of the radiating fin 6 are fixedly connected with retaining pieces 7. A scraping mechanism 8 is slidably connected to the radiating fin 6. The retaining pieces 7 effectively prevent the scraping mechanism 8 from possibly coming off the radiating fin 6 during the stirring process, ensuring that when cleaning is required, the scraping mechanism 8 can work properly, ensuring the smooth progress of production. At the same time, the sliding connection between the scraping mechanism 8 and the radiating fin 6 realizes the convenient cleaning of the radiating fin 6, reducing the maintenance difficulty and improving the overall use efficiency of the device.
[0034] Refer to Figure 2 and Figure 3, the scraping mechanism 8 includes a sliding frame 801. A resistance plate 803 is fixedly connected to the back of the sliding frame 801. One end of the sliding frame 801 is open and the other end is closed. During assembly, the heat sink 6 is inserted into the sliding frame 801 from the open end, so that the upper and lower ends of the sliding frame 801 are pressed against the upper and lower surfaces of the heat sink 6. In this way, the heat sink 6 is sleeved inside the sliding frame 801, and thus the sliding frame 801 can slide stably on the heat sink 6. Moreover, due to the existence of the notch of the sliding frame 801, the sliding frame 801 will not collide with the connecting rod 4, realizing a reliable sliding operation of the sliding frame 801 and ensuring the uniformity of the cleaning effect. At the same time, the fixed connection of the resistance plate 803 provides the necessary resistance for the scraping mechanism 8, so that the scraping mechanism 8 can closely adhere to the top of the spiral stirring blade 5 during the stirring process without interfering with the normal stirring operation, and can slide smoothly by using the resistance of water during cleaning.
[0035] Refer to Figure 2 and Figure 3 , a scraping blade 802 is fixedly connected inside the sliding frame 801. The scraping blade 802 is adapted to the heat dissipation groove 601. The adaptation of the scraping blade 802 to the heat dissipation groove 601 ensures that the scraping mechanism 8 can effectively scrape the materials inside the heat dissipation groove 601 during the sliding process, improving the thoroughness of cleaning. At the same time, the fixed connection of the scraping blade 802 enables it to remain stable during the cleaning process and will not fall off or deform due to the force during stirring or cleaning, extending the service life of the equipment.
[0036] Refer to Figure 2 and Figure 3 , there are two resistance plates 803. The two resistance plates 803 are arranged in a mirror image structure. The mirror image structure of the two resistance plates 803 enables the scraping mechanism 8 to maintain balance and stability during both the stirring and cleaning processes, improving the running stability of the equipment. At the same time, it ensures that when the scraping mechanism 8 slides on the heat sink 6, it can evenly clean the heat dissipation grooves 601, avoiding the problem of reduced heat dissipation efficiency caused by uneven cleaning.
[0037] Refer to Figure 2 and Figure 3 , there are multiple heat dissipation grooves 601 and scraping blades 802. The multiple heat dissipation grooves 601 and scraping blades 802 are arranged linearly and equidistantly. The linear equidistant arrangement of the multiple heat dissipation grooves 601 increases the heat dissipation area and improves the heat transfer efficiency, making the equipment more efficient during the heating process. At the same time, the corresponding arrangement of the multiple scraping blades 802 and the heat dissipation grooves 601 ensures that each heat dissipation groove 601 can be effectively cleaned, improving the comprehensiveness and thoroughness of cleaning, and thus maintaining the efficient operation of the equipment.
[0038] The implementation principle of the present utility model is as follows: First, when heating starts, heat is transferred to the heat sink 6 through the spiral stirring blade 5. The heat dissipation groove 601 increases the area, thereby improving the heat transfer efficiency. Then, the power device 2 is started, and the power device 2 drives the spiral stirring blade 5 to rotate through the stirring rod 3. At this time, the resistance plate 803 is subjected to the resistance of the liquid, so that it can be pressed tightly against the top of the spiral stirring blade 5 without affecting normal stirring;
[0039] After that, when cleaning is required, first, the inner wall is rinsed with high-pressure water to accumulate a certain amount of water inside. Then, the power device 2 rotates in the reverse direction. At this time, the resistance plate 803 is subjected to the resistance of the water, and thus slides down along the spiral stirring blade 5. During the sliding process, the material inside the heat dissipation groove 601 of the heat sink 6 is scraped off by the scraping blade 802 to achieve the cleaning of the heat sink 6.
[0040] Embodiment Two:
[0041] Refer to Figure 4 One side of one of the resistance plates 803 is rotatably connected to an extension plate 9 through a torsion rotating shaft. A push rod 10 is fixedly connected to the back of the extension plate 9. The connection of the extension plate 9 to the resistance plate 803 through the torsion rotating shaft enables the position of the extension plate 9 to be conveniently adjusted when needed, thereby increasing the resistance received by the resistance plate 803. At the same time, the fixed connection of the push rod 10 provides a stable support point for the extension plate 9, making the adjustment of the extension plate 9 smoother and more stable, and improving the operability and convenience of use of the device.
[0042] Refer to Figure 4 A clamping hole 11 is formed on the resistance plate 803, and the clamping hole 11 is adapted to the push rod 10. The clamping hole 11 provides a fixed clamping point for the push rod 10, enabling the extension plate 9 to remain stable when retracted, and at the same time, it can also serve as a limit when unfolded, enabling the resistance plate 803 to be horizontally unfolded and not easily moved or detached due to external forces. At the same time, when the resistance needs to be changed, the resistance plate 803 can obtain a greater resistance effect by adjusting the unfolding of the extension plate 9.
[0043] The implementation principle of the present utility model is as follows: First, when the resistance effect needs to be increased, the extension plate 9 is pulled, so that the push rod 10 fixedly connected to the back of the extension plate 9 can be disengaged from the clamping hole 11, enabling the extension plate 9 to be driven by the torsion rotating shaft to rotate and unfold. When unfolded to the horizontal position, the push rod 10 clamps the resistance plate 803 to form a larger resistance area, thereby being able to provide a greater scraping force.
[0044] Parts not involved in the present utility model are the same as or can be implemented using existing technologies, and will not be elaborated here.
[0045] Although embodiments of the present utility model have been shown and described, the specific embodiments are only interpretations of the present utility model and do not limit the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
