Description

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.

[0003] The Chinese invention application with the authorization announcement number CN113895681B discloses an automatic wrapping and packaging device for packaging film, comprising: a bottom plate; a main bracket, which is fixedly connected to the upper end surface of the left side of the bottom plate, and a push handle is connected to the middle of the front and rear sides of the main bracket; a rotating frame, which is connected to the lower end surface of the right side of the main bracket through an axis, and a motor is connected to the upper end surface of the rotating frame. 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.

[0020] The first elastic member is installed in the mounting frame and the other end is connected to the lifting portion. The first rod is installed on the lifting portion and the other end jacks up the sealing plate. When the packaging box moves, the lifting portion is pressed down, thereby driving the first rod to descend.

[0021] Preferably, the flattening mechanism includes a fixing portion, a second rod, a sliding portion, a third spring, and a control assembly;

[0027] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0028] After a layer of packing film is placed on the top of the packaging box and is conveyed towards the second plate by the conveying roller, one side of the top packing film first contacts the second plate and pushes the second plate to move towards the lifting portion. At this time, the second plate presses and fixes the side of the top packing film.

At this time, the air pressure in the inner cavity of the second piston cylinder pushes the second piston shaft to drive the first pressing wheel to the outer surface of the packaging box. Since there is more gas entering the inner cavity of the second piston cylinder, after the first pressing wheel fits on the surfaces of packaging boxes of different sizes, it is pushed by the air pressure to press tightly against the outer surface of the packaging box. Thus, after the winding device rotates and winds the packaging film, the packaging film is pressed tightly on the outer surfaces of packaging boxes of different sizes and between multiple layers of packaging films by the first pressing wheel, thereby avoiding the occurrence of loosening of the packaging film during later transportation and affecting the protection effect.

The second piston shaft 16 penetrates through the second piston cylinder 14 and is connected to the first pressing wheel 17 for pressing the packaging film; the second piston cylinder 14 is connected to the blocking mechanism; when the packaging box moves to the specified position, the piston assembly is driven to deliver gas along the air delivery assembly into the second piston cylinder 14, and the air pressure in its inner cavity drives the first pressing wheel 17 to press the packing film on the packaging box. Moreover, since the gas is compressed in the second piston cylinder 14, the first pressing wheel 17 can be pressed against the outer surfaces of packaging boxes of different sizes.

[0046] The piston assembly includes a first piston cylinder 6, a first spring 7, a first piston shaft 8, a first plate 9, and a one-way intake pipe 38;

[0047] The first piston cylinder 6 is installed inside the support portion 5. The first spring 7 is installed inside the first piston cylinder 6, and its other end is connected to the first piston shaft 8. The first piston shaft 8 penetrates through the first piston cylinder 6 and is connected to the first plate 9. The first plate 9 is located inside the flattening mechanism. The first piston cylinder 6 communicates with the one-way intake pipe 38; when the first piston shaft 8 moves towards the first plate 9, the air inside the first piston cylinder 6 is squeezed into the air delivery assembly, and when the first piston shaft 8 moves away from the first plate 9, the external air is drawn into the first piston cylinder 6 from the one-way intake pipe 38.

[0048] The air delivery assembly includes a one-way outlet pipe 10, a first rotating portion 11, a second rotating portion 12, and a telescopic pipe 13;

[0049] The intake end of the one-way outlet pipe 10 communicates with the first piston cylinder 6 and the outlet end communicates with the first rotating portion 11. The inner cavities of the first rotating portion 11 and the second rotating portion 12 are in through connection and are rotatably connected. The second rotating portion 12 is connected to the driving mechanism; the intake end of the telescopic pipe 13 penetrates through the second rotating portion 12 and the outlet end penetrates through the driving assembly and communicates with one end of the second piston cylinder 14 away from the first pressing wheel 17.

[0050] A sealing ring is provided between the second rotating portion 12 and the telescopic pipe 13. After the air enters the inner cavities of the first rotating portion 11 and the second rotating portion 12 through the one-way outlet pipe 10, it then enters the inner cavity of the second piston cylinder 14 along the telescopic pipe 13.

[0051] The one-way air outlet pipe 10 is composed of an air outlet pipe and a one-way air outlet valve. The one-way air inlet pipe 38 is composed of an air inlet pipe and a one-way air inlet valve. When the piston shaft one 8 moves towards the one-way air outlet pipe 10 in the inner cavity of the piston cylinder one 6, the air in the inner cavity of the piston cylinder one 6 is pushed out from the one-way air outlet pipe 10. When the piston shaft one 8 moves away from the one-way air outlet pipe 10 in the inner cavity of the piston cylinder one 6, the external air is drawn into the inner cavity of the piston cylinder one 6 through the one-way air inlet pipe 38.

[0052] The driving assembly includes a rotating frame 39 and a driving device two 40;

[0053] The rotating frame 39 is installed on the rotating part two 12, and a rectangular groove is formed on the side facing the piston cylinder two 14. The telescopic pipe 13 is installed in the rectangular groove; the driving device two 40 is installed on the rotating frame 39; the driving device two 40 drives the piston cylinder two 14 to lift and lower, so that the telescopic pipe 13 contracts along the rectangular groove.

[0054] The driving device two 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 piston cylinder two 14 on the side.

[0055] The driving mechanism includes a driving device one 2. The driving device one 2 is installed on the top of the mounting frame 1. The output shaft of the driving device one 2 is connected with a gear 3. The top of the mounting frame 1 is rotatably sleeved with a toothed ring 4. The gear 3 and the toothed ring 4 are meshed. The bottom end of the toothed ring 4 is connected to the rotating part two 12.

[0056] The packing mechanism is composed of a winding device 41 and a cutting device 42. The winding device 41 is connected to the rotating part two 12. The cutting device 42 is installed at the bottom of the mounting frame 1 and is located between the winding device 41 and the pressing wheel one 17. The height of the pressing wheel one 17 is higher than that of the cutting device 42.

[0057] In the prior art, in the initial state, the cutting device 42 clamps one end of the packing film. The rolled packing film is located inside the winding device 41. In the operating state, the cutting device 42 first fixes one end of the packing film. The winding device 41 drives the packing film to wind around the packaging box and winds the packing film on the surface of the packaging box. After the packing film will not loosen, the cutting device 42 releases the packing film. When it is about to finish packing, the cutting device 42 clamps the packing film again and disconnects the packing film roll and the packing film already wound on the packaging box by means of high-temperature fusing and the like, and clamps this end of the packing film for the next winding.

[0058] Example two, as Figures 1 - 5 shown, a photovoltaic module packaging device proposed by the present invention. Compared with Example one, the blocking mechanism in this embodiment includes a lifting assembly, a sealing cylinder 23, a ventilation plate 24, an elastic member two 25 and a sealing plate 26;

[0059] The lifting assembly is installed at the bottom of the mounting bracket 1; the sealing cylinder 23 is connected to one end of the second piston cylinder 14 away from the first pressing wheel 17, and the ventilation plate 24 is installed inside the sealing cylinder 23; both ends of the second 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 second piston cylinder 14 communicates with 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 second piston cylinder 14.

[0060] The lifting assembly includes a first elastic member 20, a lifting portion 21 and a first rod 22;

[0061] The first elastic member 20 is installed inside the mounting bracket 1 and the other end is connected to the lifting portion 21. The top end of the lifting portion 21 is a curved surface. The first rod 22 is installed on the lifting portion 21 and the other end jacks up the sealing plate 26; when the packaging box moves, the lifting portion 21 is pressed down, thereby driving the first rod 22 to descend.

[0062] Due to the top end of the lifting portion 21 being a curved surface, when the packaging box is conveyed to the lifting portion 21, the lifting portion 21 can be pressed down to the same height as the conveying roller 19. At the same time, one end of the first rod 22 close to the second piston cylinder 14 will descend below the rotating frame 39, thereby avoiding the situation that the rotating frame 39 and the winding device 41 are blocked by the first rod 22 during rotation.

[0063] Embodiment 3, as Figures 1 - 4 and Figures 6 - 9 shown, a photovoltaic module packaging device proposed by the present invention. Compared with Embodiment 2, the laying mechanism in this embodiment includes a fixed portion 27, a second rod 28, a sliding portion 29, a third spring 30 and a control assembly.

[0064] The fixed portion 27 is connected to the support portion 5. The second rod 28 is installed inside the fixed portion 27. The sliding portion 29 is sleeved on the second rod 28 and slides inside the fixed portion 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 portion 27 and the sliding portion 29. The control assembly is arranged inside the sliding portion 29.

[0065] The control assembly includes a third elastic member 31, a second plate 32, a fourth elastic member 33, a first clamping portion 34, a fifth elastic member 35, a second clamping portion 36, a third rod 37 and a second pressing wheel 43;

[0066] Both ends of the third elastic member 31 are respectively connected to the sliding portion 29 and the second plate 32. The fourth elastic member 33 is connected inside the second plate 32, and the other end of the fourth elastic member 33 is connected to the first clamping portion 34. The fifth elastic member 35 is installed inside the sliding portion 29, and its other end is connected to the second clamping portion 36. The third rod 37 is installed inside the fixing portion 27 and penetrates through the sliding portion 29 to press the second clamping portion 36. The second pressing wheel 43 is connected to the fixing portion 27. The packing film on the top of the packing box is first pressed by the second plate 32, and the second plate 32 is pushed. The second clamping portion 36 is separated from the third rod 37 and reset by the fifth elastic member 35. The second pressing wheel 43 presses the top packing film flat. When the second plate 32 drives the sliding portion 29 to slide along the fixing portion 27 to half, it pushes the first plate 9 to move.

[0067] A circular hole is opened in the sliding portion 29 near the third rod 37. When the sliding portion 29 is in the initial position, the third rod 37 passes through the circular hole of the sliding portion 29 to press the second clamping portion 36.

[0068] The first elastic member 20, the second elastic member 25, the third elastic member 31, the fourth elastic member 33 and the fifth elastic member 35 are all composed of a fourth spring and a telescopic rod. The fourth spring is sleeved on the outer periphery of the telescopic rod.

[0069] It further includes a runner 18 and an inclined panel 44;

[0070] The runner 18 is installed on the first pressing wheel 17, and the inclined panel 44 is installed on the side of the second plate 32 away from the second pressing wheel 43. When the first pressing wheel 17 rises to the top of the packing box during the pressing process and the packing film winds and fixes the top packing film, the runner 18 lifts the second plate 32 upward along the inclined panel 44 so that the first clamping portion 34 and the second clamping portion 36 are clamped.

[0071] In summary, in the present invention, in order to protect the top of the packing box as well, a layer of packing film is placed on the top of the packing box. The packing box is transported above the conveying roller 19, and then the conveying roller 19 is started to convey the packing box. At this time, one side of the top packing film first contacts the second plate 32 and is pressed and fixed by the second plate 32, while the second pressing wheel 43 fits with the top surface of the top packing film. Then, the second plate 32 is pushed in the direction of the lifting portion 21. At this time, since the second plate 32 has fixed one side of the top packing film, the second pressing wheel 43 unfolds and flattens the top packing film, preventing the top packing film from running off, thereby realizing the unfolding and flattening of the top packing film and avoiding gaps between the top packing film and the packing box.

[0072] When the second plate 32 moves, it drives the sliding portion 29 to move. After the sliding portion 29 moves away from the third rod 37, the second clamping portion 36 loses its limit and is driven by the elasticity of the fifth elastic member 35 to reset.

[0073] When the packing box moves above the lifting part 21, press the lifting part 21 downward, thereby driving the first rod 22 to move downward, causing the first rod 22 to leave the sealing plate 26. The second 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 closing the inner cavity of the second piston cylinder 14.

[0074] At the same time, the sliding part 29 drives the first plate 9 to move, and the first plate 9 drives the first piston shaft 8 to move within the inner cavity of the first piston cylinder 6. Thus, the air in the inner cavity of the first piston cylinder 6 is squeezed along the one-way outlet pipe 10 into the inner cavities of the first rotating part 11 and the second rotating part 12, and then transported to the inner cavity of the second piston cylinder 14 along the telescopic pipe 13. The air pressure in the inner cavity of the second piston cylinder 14 increases, driving the second piston shaft 16 to push the first pressing wheel 17 to fit with the outer surface of the packing box. When the first pressing wheel 17 fits with the outer surfaces of packing boxes of different sizes, the first pressing wheel 17 stops moving. At this time, due to the continuous input of air into the inner cavity of the second piston cylinder 14, the air pressure in the inner cavity of the second piston cylinder 14 increases, further driving the first pressing wheel 17 to press against the outer surface of the packing box.

[0075] After the packing box is in place, start the first driving device 2 to drive the gear 3 to rotate, and then drive the toothed ring 4 to rotate through the gear 3, further driving the rotating frame 39 and the winding device 41 on the second rotating part 12 to rotate. The winding device 41 winds the packing film on the outer surface of the packing box. Subsequently, the first pressing wheel 17 presses tightly between the packing film and the cardboard box, thus avoiding the situation of looseness between the packing film and the packing box.

[0076] And during the winding process, the second driving device 40 drives the second piston cylinder 14 to gradually move upward, further driving the first pressing wheel 17 to move upward. When the packing film winds around the side of the top packing film to wrap and fix the side of the packing film and the top packing film, the rotating wheel 18 fits with the inclined panel 44, thereby pushing the inclined panel 44 to move upward. The inclined panel 44 drives the second plate 32 upward, and further drives the first clamping part 34 to move upward. Through the clamping of the second clamping part 36 and the first clamping part 34, at this time, the packing box is separated from the second plate 32. After the second plate 32 loses the limit of the packing box, driven by the elasticity of the third spring 30, the sliding part 29 moves and resets in the direction of the third rod 37. The third rod 37 passes through the sliding part 29 to push the second clamping part 36 open, causing the second clamping part 36 and the first clamping part 34 to separate, thereby releasing the limit on the second plate 32 and enabling the second plate 32 to continue to fall for the next use.

[0077] When the sliding part 29 resets, the first plate 9 loses the push of the sliding part 29. Driven by the elasticity of the first spring 7, the first piston shaft 8 resets, and the first piston shaft 8 draws the external air into the inner cavity of the first piston cylinder 6 through the one-way inlet pipe 38.

[0078] After the winding is completed, the packing box is conveyed away by the conveying roller 19. After the lifting part 21 loses the limit, the elastic force of the first elastic member 20 drives the lifting part 21 to rise and reset, and then drives the first rod 22 into the inner cavity of the sealing cylinder 23 to push the sealing plate 26 upward, so that the inner cavity of the second piston cylinder 14 is communicated with the outside, and the air in the inner cavity of the second piston cylinder 14 is discharged from the sealing cylinder 23. Then, the elastic force of the second spring 15 drives the second piston shaft 16 and the first pressing wheel 17 to reset.

[0079] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
