Description

Technical Field

[0001] This utility model relates to the field of encapsulation film production technology, and in particular to a POE solar cell encapsulation film production device. Background Technology

[0002] The POE (ethylene-octene copolymer) solar cell encapsulation film production equipment is specifically designed for manufacturing POE films used in solar cell module encapsulation. As a high-performance encapsulation material, POE film is widely used in the photovoltaic industry due to its excellent weather resistance, UV aging resistance, and superior heat and low-temperature resistance. The POE solar cell encapsulation film production equipment includes processes such as raw material mixing, extrusion molding, cooling and shaping, and winding. With the rapid development of the photovoltaic industry and continuous technological advancements, the POE solar cell encapsulation film production equipment is also constantly being updated and improved.

[0003] Existing mixing machines are inefficient at mixing materials used in the production of solar cell encapsulation films, and the mixing and stirring of materials is inconvenient.

[0004] An existing patent (publication number: CN210251917U) discloses a mixing machine for producing encapsulating film for crystalline silicon solar cells. The machine includes a mixing hopper mounted on a base. The top of the mixing hopper has a feed inlet, and the bottom has a discharge outlet. A first feed pipe and a second feed pipe are located on both sides of the top of the mixing hopper. The mixing hopper contains a mixing mechanism, which includes a stepper motor. This mixing mechanism mixes the materials in the mixing hopper, and the stirring blades rapidly agitate the materials, significantly improving the efficiency of the mixing process.

[0005] To address the aforementioned issues, while existing patents offer solutions that use a mixing mechanism to mix materials in the mixing chamber and employ stirring blades to rapidly agitate the materials, significantly improving mixing efficiency, they also present challenges in scraping off the raw materials adhering to the inner wall of the device. This results in the raw materials easily sticking to the inner wall during mixing, requiring subsequent manual cleaning and thus having limited practicality. Summary of the Invention

[0006] The purpose of this invention is to provide a POE solar cell encapsulation film production device that can scrape off the raw materials adhering to the inner wall of the stirring component. Through the compression spring inside the mounting tube, the limiting block will be pushed to move under the action of the compression spring's own elasticity, thereby enabling the stirring rod to push the scraper to better contact the inner wall of the stirring component, improving the scraping effect and reducing the degree of subsequent manual cleaning, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a POE solar cell encapsulation film production device, including a screw conveyor, a conveying motor fixed to one end of the screw conveyor by bolts, a stirring mechanism for stirring raw materials provided above the screw conveyor, a connecting member connected to the other end of the screw conveyor, and a forming mechanism for extruding raw materials at the end of the connecting member;

[0008] The mixing mechanism includes a mixing component connected to the upper end of a screw conveyor. A mounting frame is fixed to the upper surface of the mixing component. A mixing motor is fixed to the upper end of the mounting frame by screws. A transmission rod is fixed to the power output shaft of the mixing motor. Four mounting tubes are symmetrically fixed to the outer wall of the transmission rod.

[0009] Preferably, one end of each of the four mounting tubes is telescopically connected to a stirring rod, and the end of the stirring rod is fixed with a scraper (36) that fits tightly against the inner wall of the stirring component.

[0010] Preferably, each of the four mounting tubes is equipped with a compression spring, and the end of the compression spring is connected to a limiting block that is fixedly connected to the stirring rod.

[0011] Preferably, the molding mechanism includes an extruder, which is fixed to the end of the connector.

[0012] Preferably, the extruder has a horizontally oriented extrusion port that communicates with the connector, and a water storage tank is fixed to the lower surface of the extruder.

[0013] Preferably, a submersible pump is fixed to the lower end of the water tank by bolts, and the output end of the submersible pump is connected to a flow chamber opened inside the extruder.

[0014] Preferably, one side of the flow chamber is connected to a return pipe that is interconnected with a water storage tank, and a heat sink is fixed on one side of the water storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The set stirring mechanism can scrape off the raw materials adhering to the inner wall of the stirring component. The compression spring inside the installation tube will push the limit block to move under the action of the compression spring itself, so that the stirring rod pushes the scraper to better contact the inner wall of the stirring component, improve the scraping effect and reduce the degree of subsequent manual cleaning.

[0017] 2. Through the set molding mechanism, the raw material is conveyed to the extruder through the connecting part. Since there is an extrusion port inside the extruder, and the flow rate of the raw material slows down when it passes through the extrusion port, and the spiral blades behind continuously convey the raw material forward, the material in the extrusion port is squeezed and shaped.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A POE solar cell encapsulation film production device includes a screw conveyor 1, a conveying motor 2 fixed to one end of the screw conveyor 1 by bolts, a stirring mechanism for stirring raw materials provided above the screw conveyor 1, a connector 4 connected to the other end of the screw conveyor 1, and a forming mechanism for extruding raw materials at the end of the connector 4.

[0028] The mixing mechanism includes a mixing element 3, which is connected to the upper end of the screw conveyor 1. A mounting frame 31 is fixed on the upper surface of the mixing element 3. A mixing motor 32 is fixed to the upper end of the mounting frame 31 by screws. A transmission rod 33 is fixed to the power output shaft of the mixing motor 32. Four mounting tubes 34 are symmetrically fixed to the outer wall of the transmission rod 33. A mixing rod 35 is telescopically connected to one end of each of the four mounting tubes 34. A scraper 36 that fits tightly against the inner wall of the mixing element 3 is fixed to the end of the mixing rod 35. A compression spring 37 is installed inside each of the four mounting tubes 34. A limiting block 38 that is fixedly connected to the mixing rod 35 is abutted to the end of the compression spring 37.

[0029] By adopting the above technical solution, before using the POE solar cell encapsulation film production device, the screw conveyor 1 is first placed in a suitable position. During use, the raw materials to be processed are poured into the mixing component 3. The stirring motor 32 set on the mounting frame 31 can drive the transmission rod 33 to rotate, thereby driving the stirring rod 35 on the mounting tube 34 to move, mixing the raw materials. When the stirring rod 35 moves, it will drive the scraper 36 to move, so that the scraper 36 scrapes off the raw materials adhering to the inner wall of the mixing component 3. Through the compression spring 37 inside the mounting tube 34, under the action of the compression spring 37 itself, the limiting block 38 will move, thereby making the stirring rod 35 push the scraper 36 to better contact the inner wall of the mixing component 3, improving the scraping effect and reducing the amount of subsequent manual cleaning. The mixed raw materials enter the screw conveyor 1, and the screw conveyor 1 is driven by the conveying motor 2 to transport the screw blades inside the screw conveyor 1.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the molding mechanism includes an extruder 5, which is fixed to the end of the connector 4. The extruder 5 has a horizontally oriented extrusion port 51 that communicates with the connector 4. A water tank 52 is fixed to the lower surface of the extruder 5. A submersible pump 53 is fixed to the lower end of the water tank 52 by bolts. The output end of the submersible pump 53 is connected to a flow cavity 54 opened inside the extruder 5. A return pipe 55 that communicates with the water tank 52 is connected to one side of the flow cavity 54. A heat sink 56 is fixed to one side of the water tank 52.

[0031] By adopting the above technical solution, the raw material is conveyed to the extruder 5 through the connector 4. Since the extruder 51 has an opening inside, and the flow rate of the raw material slows down when it passes through the extruder 51, and the spiral blades behind continuously convey the raw material forward, the material in the extruder 51 is squeezed and shaped. At this time, the submersible pump 53 installed in the water tank 52 is started, which can draw out the coolant in the water tank 52 and send it to the flow chamber 54. When the coolant passes through the flow chamber 54, it can cool the extruder 5, thereby cooling the material shaped in the extruder 51. Through the coolant continuously flowing into the flow chamber 54, under the action of the return pipe 55, the coolant can re-enter the water tank 52 for circulation. The heat sink 56 installed on the water tank 52 can absorb the heat in the coolant, and a fan can be installed on the heat sink 56 to blow air, thereby achieving the effect of cooling the coolant and ensuring the circulation effect.

[0032] Working principle: Raw materials are poured into the mixing unit 3. The mixing motor 32 drives the transmission rod 33 to rotate, which in turn drives the mixing rod 35 on the mounting tube 34 to move, mixing the raw materials. When the mixing rod 35 moves, it drives the scraper 36 to move, so that the scraper 36 scrapes off the raw materials adhering to the inner wall of the mixing unit 3. Through the compression spring 37 inside the mounting tube 34, the elasticity of the compression spring 37 makes the mixing rod 35 push the scraper 36 to better contact the inner wall of the mixing unit 3, improving the scraping effect and reducing the amount of manual cleaning work afterwards. The mixed raw materials enter the screw conveyor 1, and the screw conveyor 1 is driven by the conveying motor 2. The spiral blades of the part convey the raw material to the extruder 5 through the connector 4. When the raw material passes through the extrusion port 51, the flow rate slows down, and the spiral blades behind continuously convey the raw material forward, so that the material in the extrusion port 51 is squeezed and shaped. At this time, the submersible pump 53 installed in the water storage tank 52 starts, which can draw out the coolant in the water storage tank 52 and send it to the flow chamber 54. When the coolant passes through the flow chamber 54, it can cool the extruder 5, thereby cooling the material shaped in the extrusion port 51. Through the coolant continuously flowing into the flow chamber 54, under the action of the return pipe 55, the coolant can re-enter the water storage tank 52 for circulation.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
