Description

Technical Field

[0001] This utility model relates to the field of photovoltaic encapsulant processing technology, and in particular to a photovoltaic encapsulant raw material mixing and stirring device. Background Technology

[0002] Photovoltaic encapsulant films typically use EVA film, which is a thermosetting adhesive film used to be placed between laminated glass. Due to the superior adhesion, durability, and optical properties of EVA film, it is increasingly widely used in current modules and various optical products.

[0003] In the prior art, such as the photovoltaic encapsulant film processing mixing device in Chinese patent CN 221982184 U, there is a base plate and a mixing tank. The upper end face of the base plate is rotatably connected to a turntable, and the mixing tank is fixedly connected to the upper end face of the turntable. Multiple evenly distributed first stirring blades are fixedly connected to the inner wall of the mixing tank. The upper end face of the mixing tank is rotatably connected to a connecting plate through a bearing. The lower end of the connecting plate is fixedly connected to a rotating shaft that penetrates the upper end face of the mixing tank and extends into its interior. By causing a limiting block to enter the limiting groove, the limiting block, connecting plate, rotating shaft, and multiple second stirring blades are driven to rotate in the opposite direction through a connecting rod, thereby mixing the raw materials inside the mixing tank in the reverse direction. At the same time, the turntable, mixing tank, and multiple first stirring blades rotate in the forward direction, thereby improving the mixing efficiency. However, this patent still has the following problems.

[0004] While the aforementioned patent improves mixing efficiency, the discharge port, which runs through the lower side of the mixing tank's outer wall, may not completely empty the tank during discharge, leaving some material residue at the bottom. If this residue is not cleaned promptly, it will mix into the new material during subsequent mixing, potentially causing deviations in the film's composition and affecting product quality. Utility Model Content

[0005] This utility model mainly provides a photovoltaic film raw material mixing and stirring device that can conveniently improve discharge efficiency and prevent materials from not being discharged.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic film raw material mixing and stirring device, comprising: a support frame, wherein there are two support frames, and a rotating rod is rotatably installed on one side of each of the two support frames. A rotating plate is fixedly installed between the two rotating rods. A first motor is fixedly installed on the outer wall of one of the two support frames. The output end of the first motor passes through the support frame and is fixedly connected to the rotating rod. A second motor is fixedly installed at the bottom of the rotating plate. The output end of the second motor passes through the rotating plate and is fixedly installed with a connecting shaft. A roller is fixedly installed at the top of the connecting shaft. A discharge pipe is installed through and fixedly installed on the inner wall of the roller. A first solenoid valve is provided on the outer wall of the discharge pipe. Three evenly distributed support rods are fixedly installed at the bottom of the roller. Rollers are provided at the bottom of the support rods.

[0007] Preferably, an L-shaped plate is fixedly installed on the top of the rotating plate, and an electric telescopic rod is fixedly installed on the top of the L-shaped plate. The telescopic end of the electric telescopic rod passes through the L-shaped plate and is fixedly installed with a placement frame. A third motor is fixedly installed on the inner wall of the placement frame, and the output end of the third motor passes through the placement frame and is fixedly installed with a rotating shaft. A top cover is provided on the top of the roller, and the bottom of the rotating shaft passes through the top cover and is rotatably connected to the top cover through a bearing. Multiple sets of stirring rods are fixedly installed on the outer wall of the rotating shaft. When the operator starts the electric telescopic rod, the telescopic end of the electric telescopic rod retracts, thereby driving the placement frame to rise, which in turn drives the top cover to rise through the rotating shaft.

[0008] Preferably, the inner wall of the drum has three placement slots, a placement plate is slidably installed inside the placement slots, and multiple stirring plates are fixedly installed on the outer wall of the placement plate. The top of the placement plate is fixedly connected to the top cover, and two insert plates are fixedly installed on the top of the drum. The outer wall of the insert plates has a through slot. When the operator starts the second motor and the third motor, the drum and the rotating shaft rotate, and the stirring rod and the stirring plate rotate in opposite directions, which improves the stirring efficiency.

[0009] Preferably, the top of the cover has two through openings, an L-shaped frame is fixedly installed on the top of the cover, a cylinder is fixedly installed on the top of the L-shaped frame, the output end of the cylinder passes through the L-shaped frame and is fixedly installed with a U-shaped plate, two fixing plates are fixedly installed on the top of the cover, springs are fixedly installed on the outer walls of the fixing plates, a locking block is fixedly installed on one end of the spring, and a push plate is fixedly installed on the outer wall of the locking block. During installation, the insert plate enters the opening, and when the locking slot moves to the side of the locking block, the operator activates the cylinder, the U-shaped plate descends and contacts the inclined surface of the push plate, pushing the locking block into the locking slot, and the spring is stretched, thus completing the installation.

[0010] Preferably, a limiting rod is fixedly installed on the outer wall of the card block, and one end of the limiting rod is slidably inserted into the fixing plate to prevent the card block from tilting.

[0011] Preferably, a feed pipe is installed through and fixedly mounted on the top of the top cover, and a second solenoid valve is provided on the outer wall of the feed pipe.

[0012] Preferably, the inner wall of the opening is in contact with the outer wall of the insert plate, and the outer wall of the card block is in contact with the inner wall of the card slot. When the card block enters the card slot, the insert plate can be fixed.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when the mixing is finished, the operator starts the second motor. The output of the second motor drives the connecting shaft to rotate, which in turn drives the drum to rotate, causing the discharge pipe to face the discharge direction. At this time, the support rod drives the roller to rotate, providing support for the drum and reducing the pressure on the connecting shaft. Finally, the operator starts the first motor. The output of the first motor drives the rotating rod to rotate, which in turn drives the rotating plate to rotate. At this time, the drum tilts towards the discharge pipe. The operator then activates the first solenoid valve, allowing the material to leave from the discharge pipe. Material located at the bottom of the drum can also leave the drum along the inclined bottom surface, improving discharge efficiency and facilitating complete material removal from the drum.

[0015] 2. In this utility model, during cleaning, the worker starts the cylinder, and the output end of the cylinder drives the U-shaped plate to rise. At this time, the U-shaped plate no longer applies pressure to the push plate. At this time, the elastic force of the spring drives the locking block to leave the slot. Finally, the worker starts the electric telescopic rod, the top cover rises, and the stirring rod and stirring plate leave the drum. In this way, the worker can easily clean the stirring rod, stirring plate and inner wall of the drum, which improves the cleaning efficiency. Attached Figure Description

[0024] like Figure 1 and Figure 2As shown, an L-shaped plate 10 is fixedly installed on the top of the rotating plate 4, and an electric telescopic rod 11 is fixedly installed on the top of the L-shaped plate 10. The telescopic end of the electric telescopic rod 11 passes through the L-shaped plate 10 and is fixedly installed with a placement frame 7.

The output end of the third motor 19 passes through the placement frame 7 and is fixedly installed with a rotating shaft 14. A top cover 13 is provided on the top of the drum 12. The bottom of the rotating shaft 14 passes through the top cover 13 and is rotatably connected to the top cover 13 through a bearing. Multiple sets of stirring rods 15 are fixedly installed on the outer wall of the rotating shaft 14. When the operator starts the electric telescopic rod 11, the telescopic end of the electric telescopic rod 11 retracts, thereby driving the placement frame 7 to rise, and then driving the top cover 13 to rise through the rotating shaft 14.

[0025] like Figure 2 and Figure 3 As shown, the inner wall of the drum 12 has three placement slots 16, and a placement plate 17 is slidably installed inside the placement slots 16. Multiple stirring plates 18 are fixedly installed on the outer wall of the placement plate 17. The top of the placement plate 17 is fixedly connected to the top cover 13. Two insert plates 25 are fixedly installed on the top of the drum 12. The outer wall of the insert plate 25 has a through slot 26. When the operator starts the second motor 5 and the third motor 19, the drum 12 and the rotating shaft 14 rotate, and the stirring rod 15 and the stirring plate 18 rotate in opposite directions, which improves the stirring efficiency.

[0026] like Figure 3 and Figure 4 As shown, the top of the top cover 13 has two openings 24. An L-shaped frame 27 is fixedly installed on the top of the top cover 13. A cylinder 28 is fixedly installed on the top of the L-shaped frame 27. The output end of the cylinder 28 passes through the L-shaped frame 27 and is fixedly installed with a U-shaped plate 29. Two fixing plates 30 are fixedly installed on the top of the top cover 13. A spring 31 is fixedly installed on the outer wall of the fixing plate 30. A locking block 32 is fixedly installed on one end of the spring 31. A push plate 34 is fixedly installed on the outer wall of the locking block 32. During installation, the insert plate 25 enters the opening 24. When the slot 26 moves to the side of the locking block 32, the operator starts the cylinder 28. The U-shaped plate 29 descends and contacts the inclined surface of the push plate 34, pushing the locking block 32 into the slot 26. The spring 31 is stretched, and the installation is completed.

[0027] like Figure 4 As shown, a limiting rod 33 is fixedly installed on the outer wall of the locking block 32. One end of the limiting rod 33 is slidably inserted into the fixing plate 30 to prevent the locking block 32 from tilting.

[0028] like Figure 2 As shown, a feed pipe 22 is installed through and fixedly mounted on the top of the top cover 13. A second solenoid valve 23 is provided on the outer wall of the feed pipe 22. When feeding, the operator starts the second solenoid valve 23, and then puts the material into the drum 12 through the feed pipe 22.

[0029] like Figure 3 and Figure 4 As shown, the inner wall of the opening 24 fits against the outer wall of the insert plate 25, and the outer wall of the locking block 32 fits against the inner wall of the slot 26. When the locking block 32 enters the slot 26, the insert plate 25 can be fixed.

[0030] The operating method and working principle of this device are as follows: During use, the operator feeds the material into the drum 12 through the feed pipe 22. Then, the second motor 5 and the third motor 19 are started. The drum 12 and the rotating shaft 14 rotate, while the stirring rod 15 and the stirring plate 18 rotate in opposite directions, improving stirring efficiency. When stirring is finished, the operator starts the second motor 5. The output of the second motor 5 drives the connecting shaft 6 to rotate, which in turn drives the drum 12 to rotate, causing the discharge pipe 20 to face the discharge direction. At this time, the support rod 8 drives the roller 9 to rotate, providing support for the drum 12 and reducing the pressure on the connecting shaft 6. Finally, the operator starts the first motor 3. The output of the first motor 3 drives the rotating rod 2 to rotate, which in turn drives the rotating plate 4 to rotate. At this time, the drum 12 tilts towards the discharge pipe 20. The operator then activates the first solenoid valve 21, allowing the material to leave from the discharge pipe 20. Material located on the bottom surface inside the drum 12 can also leave the drum 12 along the tilted bottom surface, improving discharge efficiency and facilitating complete material removal from the drum 12. During cleaning, the staff starts the cylinder 28, and the output end of the cylinder 28 drives the U-shaped plate 29 to rise. At this time, the U-shaped plate 29 no longer applies pressure to the push plate 34. The elastic force of the spring 31 drives the locking block 32 to leave the slot 26. Finally, the staff starts the electric telescopic rod 11, and the top cover 13 rises, driving the stirring rod 15 and the stirring plate 18 to leave the drum 12. This makes it convenient for the staff to clean the stirring rod 15, the stirring plate 18 and the inner wall of the drum 12, improving the cleaning efficiency.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
