Description

Technical Field

[0001] The utility model relates to the field of preparation of adhesives for photovoltaic backsheets, and particularly relates to a stirring device for preparing adhesives for photovoltaic backsheets. Background Technique

[0002] As a kind of clean energy with high efficiency, stability, environmental protection and rich reserves, solar energy is the most popular research direction in the new energy field in recent years. The main function of the photovoltaic backsheet is to protect the solar cell module from the erosion of outdoor environmental factors, playing roles such as insulation, weather resistance, protection, and support. It is a key encapsulation material for protecting solar modules to be used outdoors for a long time. The backsheet usually adopts a composite type, generally having a three-layer structure: the outer layer is a weather-resistant layer such as fluorine film (PVF / PVDF), which has good resistance to environmental erosion; the middle layer is a PET polyester film, which plays a supporting role; the inner layer is a lamination bonding layer, which is bonded to EVA. The adhesive for photovoltaic backsheets bonds the three-layer film structure together to form the backsheet.

[0003] In the prior art, the adhesive for photovoltaic backsheets is prepared by mixing raw materials such as polyester resin, hydroxyl acrylic resin, curing agent, heat stabilizer, antioxidant, etc. Since the photovoltaic backsheet has very high requirements for the dispersion uniformity of each component of the backsheet adhesive, and the structure of the stirring device is relatively single. Generally, after the output end driven by a stirring motor drives the stirring shaft to rotate, the raw materials in the stirring barrel are stirred by the stirring blades at the bottom end of the stirring shaft. When more raw materials need to be mixed, a stirring barrel with a corresponding capacity needs to be replaced. However, it is difficult to fix stirring barrels of different sizes after the existing stirring barrels are replaced. And since the stirring blades are generally fixed to the stirring shaft, it is impossible to replace stirring blades of different sizes and models according to the raw material capacity for stirring use. Moreover, the stirring is realized at the same position during the stirring process. Thus, when preparing the adhesive for photovoltaic backsheets, the stirring and mixing effect and efficiency of the raw materials are reduced, and further the purpose of quickly and uniformly dispersing and stirring and mixing the adhesive cannot be achieved.

The servo motor 22 is fixedly installed on the bottom surface of the lower fixed plate 18, and the output end of the servo motor 22 is fixedly installed together with the lower second rotating rod 21. A second screw hole 24 is formed in the top surface of the moving plate 23 and is threadedly connected with the unidirectional screw rod 20 through the second screw hole 24. The moving plate 23 passes through the moving port 16. Sliders 25 are fixedly installed on both sides of the moving plate 23 respectively, and the sliders 25 are movably installed in the sliding ports 17. After the servo motor 22 is started to drive the output end to drive the second rotating rod 21 to rotate in the second rotating hole 19, the second rotating rod 21 will drive the unidirectional screw rod 20 to rotate, so that the moving plate 23 moves up and down in the moving port 16 formed on the front end wall of the support plate 15 along the unidirectional screw rod 20 through the second screw hole 24, and the sliders 25 on both sides of the moving plate 23 slide in the sliding ports 17.

A threaded sleeve 28 is fixedly installed at the bottom end of the stirring shaft 27. A threaded short rod 30 is fixedly installed at the top end of the stirring blade 29, and the threaded short rod 30 is threadedly connected with the threaded sleeve 28. After selecting a stirring blade 29 with a corresponding size model according to the size of the stirring barrel and the mixing amount of the raw materials, the threaded short rod 30 is screwed into the threaded sleeve 28 and threadedly connected with it, and the stirring blade 29 can be installed at the bottom end of the stirring shaft 27. The stirring motor 26 is started to drive the output end to drive the stirring shaft 27 to rotate, the stirring shaft 27 will drive the stirring blade 29 to rotate, and the stirring blade 29 will complete the stirring and mixing of the raw materials in the stirring barrel.

[0027] It should be noted that the present utility model is a stirring device for preparing an adhesive for a photovoltaic backplane. Before stirring, a stirring barrel with a corresponding capacity is selected according to the raw material mixing amount. The stirring barrel is placed between the symmetrically arranged movable plates 11 on the left and right. The knob 10 is rotated, and the first rotating rod 9 is driven by the knob 10 to rotate in the first rotating hole 6 opened on the side wall of the side plate 5. The first rotating rod 9 will drive the bidirectional screw rod 8 to rotate between the side plates 5, so that the symmetrically arranged movable plates 11 respectively make relative movement operations along the bidirectional screw rod 8 through the first screw holes 12 on the side walls. When moving, the guide rods 13 installed on the outer side walls of the movable plates 11 will move in the guide holes 7 opened on the side walls of the side plates 5 until the arc-shaped clamping plates 14 installed at the front end parts of the opposite side walls of the symmetrically arranged movable plates 11 are closely attached to the outer wall of the stirring barrel, and after the knob 10 can no longer be rotated, the purpose of quickly replacing the stirring barrel according to the raw material mixing amount can be achieved. By clamping and fixing the stirring barrel between the arc-shaped clamping plates 14, the problem of displacement and shaking of the stirring barrel during the stirring process can be avoided. After selecting a stirring blade 29 with a corresponding size and model according to the size of the stirring barrel and the raw material mixing amount, the threaded short rod 30 is screwed into the threaded sleeve 28 and threadedly connected thereto, and the stirring blade 29 can be installed at the bottom end of the stirring shaft 27 to achieve the purpose of replacing different sizes and models of stirring blades 29 according to the raw material mixing amount and the size of the stirring barrel to stir the raw materials. The stirring motor 26 is started to drive the output end to drive the stirring shaft 27 to rotate. The stirring shaft 27 will drive the stirring blade 29 to rotate, and the stirring blade 29 will stir and mix the raw materials in the stirring barrel. At the same time, the servo motor 22 installed on the bottom surface of the fixed plate 18 below the rear end of the support plate 15 is started. The servo motor 22 will drive the output end to drive the second rotating rod 21 to rotate in the second rotating hole 19 opened on the top surface of the fixed plate 18. The second rotating rod 21 will drive the unidirectional screw rod 20 to rotate, so that the moving plate 23 moves up and down in the movable opening 16 opened on the front end wall of the support plate 15 through the second screw hole 24 opened on the top surface along the unidirectional screw rod 20. The sliding blocks 25 on both sides of the moving plate 23 slide in the sliding openings 17. In this way, the stirring position of the stirring blade 29 can be adjusted up and down during the stirring process, and the purpose of achieving up and down stirring and mixing of the raw materials in the stirring barrel can be achieved. Thus, by replacing the stirring blade 29 and continuously changing the up and down stirring position of the stirring blade 29 in the stirring barrel, the stirring and mixing effect and efficiency of the raw materials are improved, and further, the function of quickly and uniformly dispersing and stirring and mixing the adhesive can be achieved.
