Description

Technical Field

[0001] This application relates to the field of blending extrusion technology, and in particular to a multifunctional masterbatch blending extrusion equipment for the production of rare earth-converted light agricultural film. Background Technology

[0002] Rare earth light-converting agricultural film is produced by blending and extruding rare earth light-converting masterbatches prepared with rare earth light-converting agents and other functional masterbatches, and then molding them in a mold. Rare earth light-converting agents are a new type of functional material with light conversion capabilities, which can be widely used in fields such as optical fiber communication, agricultural films, bioanalytical sensors, and laser technology.

[0003] In existing technologies, masterbatches with different functions need to be uniformly mixed using a high-speed mixer before entering the extrusion equipment. However, due to the differences in the physical properties of the various functional masterbatches, the uniformity of the functional masterbatches decreases after entering the extrusion equipment, affecting the quality of the produced rare earth-converted agricultural film.

[0004] Therefore, it is necessary to propose a multifunctional masterbatch blending and extrusion equipment for the production of rare earth-converted light agricultural film, so as to improve the quality of rare earth-converted light agricultural film, which has become an important technical problem that needs to be solved urgently.

However, due to the differences in the physical properties of the various functional masterbatches, the uniformity of the functional masterbatches decreases after entering the extrusion equipment, affecting the quality of the produced rare earth-converted light-emitting agricultural film.

[0006] To achieve the above objectives, this application proposes a multifunctional masterbatch blending extrusion equipment for rare earth-to-light agricultural film production, comprising: a base; an extrusion cylinder disposed on the base; an extrusion screw rotatably disposed inside the extrusion cylinder; an extrusion drive disposed on the base and connected to the extrusion screw; a feed inlet disposed on the extrusion cylinder; and stirring blades disposed near the feed inlet on the extrusion screw.

[0023] See Figure 1 , Figure 2 and Figure 3 As shown, this application proposes a multifunctional masterbatch blending extrusion equipment for rare earth-to-light agricultural film production, comprising: a base 1; an extrusion cylinder 11 disposed on the base 1; an extrusion screw 10 rotatably disposed within the extrusion cylinder 11; an extrusion drive 2 disposed on the base 1 and connected to the extrusion screw 10; a feed inlet 9 disposed on the extrusion cylinder 11; and a stirring blade 102 disposed adjacent to the feed inlet 9 on the extrusion screw 10.

[0024] Rare earth light-converting agricultural film is produced by blending and extruding rare earth light-converting masterbatch (prepared using rare earth light-converting agents) with other functional masterbatches, and then molding it in a mold. Rare earth light-converting masterbatch is a functional masterbatch used in plastics processing. Its main function is to convert ultraviolet and green light from sunlight into red-orange and blue light beneficial to plant growth, significantly improving crop yield and quality. Other functional masterbatches include anti-aging masterbatch, anti-fogging masterbatch, anti-static masterbatch, and heat-insulating masterbatch. No specific restrictions are placed on the types of functional masterbatches used here; selection should be based on actual needs.

[0025] The base 1 is the structural foundation of the multifunctional masterbatch blending extrusion equipment for rare earth-to-light agricultural film production. All other structures on the equipment are directly or indirectly connected to the base 1. The functional masterbatch enters the extrusion cylinder 11 through the feed inlet 9. Under the combined action of the extrusion screw 10 and the extrusion cylinder 11, the various functional masterbatches melt and homogenize to obtain a uniform melt. The melt is then formed in a mold to obtain the rare earth-to-light agricultural film. The extrusion drive 2 is a motor that drives the extrusion screw 10 to rotate. A speed reduction transmission structure is provided between the output end of the extrusion drive 2 and the extrusion screw 10. Since this speed reduction transmission structure is a mature existing technology, no specific limitations are imposed on it here.

[0026] The stirring blade 102 is the core structure of the multifunctional masterbatch blending extrusion equipment for rare earth-to-light agricultural film production. A blending section is located near the feed inlet 9 on the extrusion screw 10. The blending section is integrally formed with the extrusion screw 10, and its diameter is smaller than that of other parts of the extrusion screw 10 to provide installation space for the stirring blade 102. The stirring blade 102 includes multiple blades evenly spaced along the circumference of the blending section, used to stir various functional masterbatches and improve their uniformity. Preferably, the blades are integrally formed with the blending section.

[0027] Specifically, the rare earth light-converting masterbatch and other functional masterbatches required for manufacturing rare earth light-converting agricultural film are mixed evenly. The evenly mixed functional masterbatch enters the extrusion cylinder 11 through the feed inlet 9. After the functional masterbatch enters the extrusion cylinder 11, the various functional masterbatches are stirred by the stirring blades 102 to improve the uniformity of the various functional masterbatches, thereby improving the quality of the final rare earth light-converting agricultural film. Under the combined action of the extrusion screw 10 and the extrusion cylinder 11, the evenly mixed functional masterbatch melts and homogenizes to obtain a uniform melt. The melt is then formed in the mold to obtain the rare earth light-converting agricultural film.

[0028] See Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the system further includes: a chamfered section 101 disposed on the extrusion screw 10; a chamfered section 101 is provided between one end of the blending section and the extrusion screw 10 to avoid large stress concentration at the connection between the blending section and the extrusion screw 10; and an arc-shaped transition section 103 disposed on the extrusion screw 10. An arc-shaped transition section 103 is provided between the other end of the blending section and the extrusion screw 10. The arc-shaped transition section 103 can avoid stress concentration and can prevent the functional masterbatch from being stuck at the connection between the other end of the blending section and the extrusion screw 10.

[0029] In this embodiment, multiple chamfered sections 101 can be provided, that is, multiple chamfered sections 101 are provided at intervals between one end of the blending section and the extrusion screw 10, so as to better avoid large stress concentration at the connection between the blending section and the extrusion screw 10.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the system further includes: multiple air-cooled boxes 6 disposed on the extrusion cylinder 11; a blower 3 disposed on the air-cooled box 6, the blower 3 having an air inlet; and an exhaust port 7 disposed on the air-cooled box 6. The blower 3 is used to draw air from outside the air inlet into the air-cooled box 6 and discharge it from the exhaust port 7 of the air-cooled box 6 to form a cooling airflow. The cooling airflow is used to remove heat from the extrusion cylinder 11 and cool the melt inside the extrusion cylinder 11. Multiple heating jackets 12 are disposed on the outside of the extrusion cylinder 11. The heating jackets 12 are heated by electric heating and transfer the heat to the extrusion cylinder 11 to heat the melt inside the extrusion cylinder 11. A temperature probe 4 is disposed on the extrusion cylinder 11. The temperature probe 4 is used to measure the temperature of the melt inside the extrusion cylinder 11. Since the temperature probe 4 for measuring the temperature of the melt inside the extrusion cylinder 11 is mature prior art, its structure is not specifically limited here.

[0031] In this embodiment, a maintenance window is rotatably provided on the air-cooled box 6, and a handle 8 is provided on the maintenance window for easy opening. A connection hole is provided on the heating jacket 12, and a matching threaded hole 13 is provided at the corresponding position on the extrusion cylinder 11. The heating jacket 12 is fixed to the extrusion cylinder 11 by insulating screws.

[0032] In the extrusion process, the extrusion barrel 11 has multiple stages. Each stage of the extrusion barrel 11 is equipped with a heating jacket 12 and an air-cooling box 6 on its outer side. Temperature probes 4 are also installed on each stage of the extrusion barrel 11. The extrusion barrel 11 includes a feeding section, a compression section, a homogenization section, a metering section, and a discharge section. The feeding section requires temperature control to effectively soften the functional masterbatch; the compression section requires temperature control to fully melt the functional masterbatch; the homogenization section requires temperature control to further plasticize and homogenize the functional masterbatch; the metering section requires temperature control to ensure the functional masterbatch is completely melted and maintains thermal stability for uniform extrusion; and the discharge section requires temperature control to ensure smooth melt flow and effectively prevent melt scorching and decomposition. The extrusion equipment also has a control terminal, preferably a CPU. The temperature probes 4 in each section of the extrusion barrel 11 send temperature signals to the control terminal. The control terminal then activates the blower 3 or the heating jacket 12 based on the temperature of each section to maintain the temperature of each section within the extrusion barrel 11. The temperature of each section inside the extrusion cylinder 11 can be selected according to the specific processing conditions.

[0033] See Figure 1 and Figure 2 As shown, in some embodiments, it further includes: a discharge port 5, which is disposed at the end of the extrusion cylinder 11 and is connected to a forming mold. The melt flows from the discharge port 5 into the forming mold to form a rare earth-converted light-emitting agricultural film.

All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
