Technical Field

[0001] The present invention relates to the technical field of packaging devices, and in particular to a photovoltaic component packaging device. Background Art

[0002] Photovoltaic modules are electronic devices that use the photovoltaic effect to convert solar energy into electrical energy. After the photovoltaic modules are produced, they are packed in containers such as cartons, and then multiple packaging boxes containing photovoltaic modules are stacked. The packaging film is then evenly wrapped using a packaging film packaging device to facilitate subsequent transportation.

The above-mentioned prior art can facilitate the automatic wrapping and packaging of the stacked goods as a whole, thereby improving the efficiency of the packaging film wrapping and packaging, and can facilitate the adjustment of the wrapping density of the packaging film, so as to adapt to the packaging needs of different goods, and can facilitate the rapid replacement of the used packaging film.

[0004] However, when wrapping and packing the boxes, in order to adapt to boxes of different sizes, the wrapping equipment of the packing film is far away from the boxes. This results in some gaps between the packing film and the boxes and between the multiple layers of the packing film when the packing film is rotated and wrapped. This causes the packing film to become loose at a later stage, allowing dust and water vapor to enter, thereby affecting the protective effect of the packing film on the boxes.

[0022] The gas delivery assembly includes a one-way gas outlet pipe 10, a rotating part 11, a rotating part 2 12 and a telescopic pipe 13; The inlet end of the one-way air outlet pipe 10 is connected to the piston cylinder 16 and the outlet end is connected to the rotating part 11. The inner cavities of the rotating part 11 and the rotating part 2 12 are connected and rotatably connected. The rotating part 2 12 is connected to the driving mechanism; the inlet end of the telescopic tube 13 passes through the rotating part 2 12 and the outlet end passes through the driving assembly and is connected to the end of the piston cylinder 2 14 away from the clamping wheel 17.

[0023] A sealing ring is provided between the second rotating part 12 and the telescopic tube 13 , and air enters the inner cavity of the first rotating part 11 and the second rotating part 12 through the one-way air outlet pipe 10 , and then enters the inner cavity of the second piston cylinder 14 along the telescopic tube 13 .

When the piston shaft 8 moves in the inner cavity of the piston cylinder 6 toward the direction of the one-way air outlet pipe 10, the air in the inner cavity of the piston cylinder 6 is pushed out from the one-way air outlet pipe 10. When the inner cavity of the piston cylinder 6 moves away from the one-way air outlet pipe 10, the piston shaft 8 draws external air into the inner cavity of the piston cylinder 6 through the one-way air inlet pipe 38.

[0025] The driving assembly includes a rotating frame 39 and a driving device 2 40; The rotating frame 39 is installed on the rotating part 12, and a rectangular groove is opened on the side facing the piston cylinder 14, and the telescopic tube 13 is installed in the rectangular groove; the driving device 40 is installed on the rotating frame 39; the driving device 40 drives the piston cylinder 14 to rise and fall so that the telescopic tube 13 contracts along the rectangular groove.

[0026] The second driving device 40 is composed of a linear guide rail and a moving seat. The moving seat is installed on the moving end of the linear guide rail and is connected to the second piston cylinder 14 on the side.

[0027] The driving mechanism includes a driving device 2, which is installed on the top of the mounting frame 1. The output shaft of the driving device 2 is connected to a gear 3.

The cutting device 42 is installed at the bottom of the mounting frame 1 and is located between the winding device 41 and the pressure wheel 17. The height of the pressure wheel 17 is higher than the cutting device 42.

[0029] In the prior art, in the initial state, the cutting device 42 clamps one end of the packaging film, and the rolled packaging film is located in the winding device 41. In the operating state, the cutting device 42 first fixes one end of the packaging film, and the winding device 41 drives the packaging film roll to rotate around the packaging box, and wraps the packaging film on the surface of the packaging box. After the packaging film is not loose, the cutting device 42 loosens the packaging film. When the packaging is about to be completed, the cutting device 42 clamps the packaging film again and uses high-temperature fusing or other methods to disconnect the packaging film roll and the packaging film that has been wrapped around the packaging box, and clamps this end of the packaging film for the next winding.

[0030] Embodiment 2, as Figure 1-Figure 5 As shown, a photovoltaic module packaging device proposed by the present invention, compared with the first embodiment, the blocking mechanism of this embodiment includes a lifting assembly, a sealing cylinder 23, a vent plate 24, a second elastic member 25 and a sealing plate 26; The lifting assembly is installed at the bottom of the mounting frame 1; the sealing cylinder 23 is connected to the end of the piston cylinder 14 away from the clamping wheel 17, and the ventilation plate 24 is installed in the sealing cylinder 23; the two ends of the elastic member 25 are respectively connected to the ventilation plate 24 and the sealing plate 26; when the sealing plate 26 is lifted by the lifting assembly, the inner cavity of the piston cylinder 14 is connected to the outside through the sealing cylinder 23, and when the lifting assembly descends, the sealing plate 26 blocks the sealing cylinder 23 to seal the piston cylinder 14.

[0031] The lifting assembly includes an elastic member 20, a lifting portion 21 and a rod 22; The elastic member 20 is installed in the mounting frame 1 and the other end is connected to the lifting part 21. The top of the lifting part 21 is a curved surface. The rod 22 is installed on the lifting part 21 and the other end lifts the sealing plate 26. The movement of the packaging box presses the lifting part 21 downward, thereby driving the rod 22 to descend.

[0032] By making the top of the lifting part 21 a curved surface, when the packaging box is conveyed to the lifting part 21, the lifting part 21 can be pressed down to the same height as the conveying roller 19. At the same time, the end of the rod 22 close to the piston cylinder 14 will drop to the bottom of the rotating frame 39, thereby avoiding the situation where the rotating frame 39 and the winding device 41 are blocked by the rod 22 when rotating.

[0033] Embodiment three, as Figure 1-Figure 4 and Figure 6-Figure 9As shown, a photovoltaic module packaging device proposed by the present invention, compared with the second embodiment, the flattening mechanism of this embodiment includes a fixing part 27, a second rod 28, a sliding part 29, a third spring 30 and a control component.

[0034] The fixed part 27 is connected to the supporting part 5, the second rod 28 is installed in the fixed part 27, the sliding part 29 is sleeved on the second rod 28 and slides in the fixed part 27, the third spring 30 is arranged on the outer periphery of the second rod 28 and its two ends are respectively connected to the fixed part 27 and the sliding part 29, and the control component is arranged in the sliding part 29.

[0035] The control assembly includes an elastic member 31, a plate 2 32, an elastic member 4 33, a clamping portion 1 34, an elastic member 5 35, a clamping portion 2 36, a rod 3 37 and a clamping wheel 2 43; The two ends of the elastic member 31 are connected to the sliding part 29 and the plate 2 32 respectively, the elastic member 4 33 is connected inside the plate 2 32, and the other end of the elastic member 4 33 is connected to the clamping part 1 34; the elastic member 5 35 is installed inside the sliding part 29, and the other end thereof is connected to the clamping part 2 36; the rod 37 is installed inside the fixed part 27 and penetrates the sliding part 29 to squeeze the clamping part 2 36; the pressing wheel 2 43 is connected to the fixed part 27. The packing film on the top of the packaging box is first pressed by the plate 2 32, and the plate 2 32 is pushed, the clamping part 2 36 is separated from the rod 3 37 and reset by the elastic member 5 35, the pressing wheel 2 43 presses the top packing film flat, and the plate 2 32 drives the sliding part 29 to slide along the fixed part 27 to push the plate 1 9 to move.

[0036] A circular hole is formed in the sliding portion 29 near the rod three 37 . When the sliding portion 29 is located at the initial position, the rod three 37 passes through the circular hole of the sliding portion 29 to squeeze the clamping portion two 36 .

[0037] The elastic member 1 20, the elastic member 25, the elastic member 31, the elastic member 4 33 and the elastic member 5 35 are all composed of a spring 4 and a telescopic rod, and the spring 4 is sleeved on the outer periphery of the telescopic rod.

[0038] Also includes a rotating wheel 18 and an inclined plate 44; The rotating wheel 18 is installed on the clamping wheel 17, and the inclined panel 44 is installed on the side of the plate 2 32 away from the clamping wheel 2 43; the clamping wheel 17 rises to the top of the packaging box during the clamping process, and when the packaging film wraps and fixes the top packaging film, the rotating wheel 18 lifts the plate 2 32 upward along the inclined panel 44, so that the clamping part 1 34 and the clamping part 2 36 are clamped.

[0039] In summary, in the present invention, in order to protect the top of the packaging box as well, a layer of packaging film is placed on the top of the packaging box, the packaging box is transported to the top of the conveyor roller 19, and then the conveyor roller 19 is started to convey the packaging box. At this time, one side of the top packaging film first contacts the second plate 32 and is pressed and fixed by the second plate 32, and the second pressure wheel 43 is in contact with the top surface of the top packaging film, and then the second plate 32 is pushed to move in the direction of the lifting part 21. At this time, since the second plate 32 has fixed one side of the top packaging film, the second pressure wheel 43 stretches and flattens the top packaging film and does not let the top packaging film deviate, thereby achieving the stretching and flattening of the top packaging film and avoiding the existence of a gap between the top packaging film and the packaging box.

[0040] When the second plate 32 moves, the sliding part 29 is driven to move. After the sliding part 29 moves away from the third rod 37, the second clamping part 36 loses its limit position and is reset by the elasticity of the fifth elastic member 35.

[0041] When the packaging box moves to the top of the lifting part 21, the lifting part 21 is pressed downward, thereby driving the rod 1 22 to move downward, so that the rod 1 22 leaves the sealing plate 26, and the elastic member 25 releases its elasticity to drive the sealing plate 26 to descend and fit with the bottom end of the sealing cylinder 23, thereby sealing the inner cavity of the piston cylinder 2 14.

[0042] At the same time, the sliding part 29 drives the plate 19 to move, and the plate 19 drives the piston shaft 18 to move in the inner cavity of the piston cylinder 16, so that the air in the inner cavity of the piston cylinder 16 is squeezed into the inner cavity of the rotating part 11 and the rotating part 2 12 along the one-way air outlet pipe 10, and then transported to the inner cavity of the piston cylinder 2 14 along the telescopic tube 13. The air pressure in the inner cavity of the piston cylinder 2 14 increases, driving the piston shaft 2 16 to push the clamping wheel 17 to fit the outer surface of the packaging box. When the clamping wheel 17 fits the outer surface of packaging boxes of different sizes, the clamping wheel 17 stops moving. At this time, since the inner cavity of the piston cylinder 2 14 is continuously input with air, the air pressure in the inner cavity of the piston cylinder 2 14 increases, thereby driving the clamping wheel 17 to press against the outer surface of the packaging box.

[0043] When the packaging box is in place, the driving device 2 is started to drive the gear 3 to rotate, and the gear 3 then drives the gear ring 4 to rotate, thereby driving the rotating frame 39 and the winding device 41 on the rotating part 12 to rotate. The winding device 41 wraps the packaging film around the outer surface of the packaging box, and then the clamping wheel 17 presses the packaging film and the carton tightly, thereby preventing the packaging film and the packaging box from being loose.

[0044] The second clamping portion 36 is then engaged with the first clamping portion 34, and the second clamping portion 36 is engaged with the first clamping portion 34.

[0045] When the sliding part 29 is reset, the plate 9 loses the push of the sliding part 29, and the piston shaft 8 is driven to reset through the elasticity of the spring 7. The piston shaft 8 draws external air into the inner cavity of the piston cylinder 6 through the one-way air inlet pipe 38.

[0046] When the wrapping is completed, the packaging box is transported away by the conveying roller 19. After the lifting part 21 loses its limit, the elasticity of the elastic member 20 drives the lifting part 21 to rise and reset, thereby driving the rod 22 to enter the inner cavity of the sealing cylinder 23 to push the sealing plate 26 upward, so that the inner cavity of the piston cylinder 14 is connected with the outside, so that the air in the inner cavity of the piston cylinder 14 is discharged from the sealing cylinder 23, and then the elasticity of the spring 15 drives the piston shaft 16 and the clamping wheel 17 to reset.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
