The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0025] like Figure 1-3 As shown, a photovoltaic film winding and cutting device to prevent loosening includes a frame 1, a supporting roller 2 is arranged on the photovoltaic film 40 discharge port of the frame 1, a side plate 3 is arranged on the side of the frame 1 close to the supporting roller 2, a winding component 4, a cutting component 5, a pressing component 6 and a tape assembly 7 are arranged on the side plate 3, the pressing component 6 is located above the winding component 4, the cutting component 5 is located between the pressing component 6 and the supporting roller 2, and the tape assembly 7 is located on the side of the winding component 4 away from the cutting component 5;

[0026] The adhesive tape assembly 7 includes a housing 71, a driving rod 72 and a first driver 73. The housing 71 is provided with a mounting cavity for placing the adhesive tape 10. A non-rotatable adhesive tape mounting shaft 74 is provided in the mounting cavity. The adhesive tape 10 is provided on the adhesive tape mounting shaft 74. An air expansion sleeve 75 is sleeved on the outer side of the adhesive tape mounting shaft 74. A cutting tooth 711 is provided at the outlet of the adhesive tape 10 of the housing 71. A adhesive tape guide roller 76 is provided in the housing 71 located at the outlet of the adhesive tape 10.

[0027] One end of the driving rod 72 is fixedly connected to the side of the housing 71, and the other end is connected to the driving end of the first driver 73, and the first driver 73 is arranged on the side plate 3;

[0028] It also includes a controller 8 , which is electrically connected to the first driver 73 , the winding assembly 4 , the cutting assembly 5 , and the pressing assembly 6 .

[0029] In this embodiment, the working principle is as follows: when the photovoltaic film 40 (roll material) wound on the winding component 4 reaches a set thickness, the controller 8 controls the winding component 4 to stop working, and then the pressing component 6 drives to press the roll material, and then the cutting component 5 drives to cut the photovoltaic film 40 between the support roller 2 and the winding component 4. At this time, the roll material loses tension due to cutting, but due to the action of the pressing component 6, the roll material will not be unwound or loose; then the controller 8 controls the first driver 73 to drive the outer shell 71 to rotate until the outlet side of the tape 10 of the outer shell 71 is close to the roll material (at this time, the inflation sleeve 75 is in a non-inflated state, that is, the tape 10 can rotate relative to the tape installation shaft 74), and then the winding component 4 continues to rotate at a set speed, thereby driving the tape 10 adhered to the surface of the roll material to wrap around the roll material until the free edge of the roll material is sealed;

[0030] After the free edge of the roll material is sealed, the inflatable sleeve 75 is turned into an inflated state, that is, the tape 10 cannot rotate relative to the tape installation shaft 74, and then the tape 10 is cut under the action of the rotating force of the winding component 4 and the cutting teeth 711. After the tape 10 is cut, the cutting component 5 and the clamping component 6 can be reset.

[0031] In the embodiment, the coil is compressed by the compression assembly 6 and the tape guide roller 76 to prevent the coil from being unwound or loose.

[0032] In this embodiment, the above structure enables the photovoltaic film 40 to be automatically rolled up, cut, pressed and sealed at the free edge of the roll, which not only prevents the photovoltaic film 40 roll from unwinding and loosening, but also improves the rolling efficiency and reduces the rolling cost.

[0033] Further, such as Figure 1-3 The housing 71 is provided with a first sensor 20, and the first sensor 20 is used to determine whether the tape 10 is used up by monitoring the thickness of the tape 10;

[0034] The first sensor 20 is electrically connected to the controller 8 .

[0035] In this embodiment, the above structure can timely know the use of the tape 10 and ensure that the photovoltaic film 40 is rolled up stably and reliably.

[0036] Further, such as Figure 1-3The winding assembly 4 shown includes a winding roller 41 and a winding drive 42 ; a second sensor 30 is arranged below the winding roller 41 , and the second sensor 30 is used to monitor the thickness of the coiled material. The second sensor 30 is electrically connected to the controller 8 .

[0037] In this embodiment, the above structure can monitor the thickness of the coil in real time through the second sensor 30 to control the driving of the cutting component 5, the clamping component 6, the winding component 4 and the tape application component 7, thereby automatically cutting, clamping and sealing the free edge of the coil after the winding is completed, thereby improving the winding efficiency and reducing the winding cost.

[0038] Further, such as Figure 1-3 The cutting assembly 5 shown includes a cutter head 51, a pad 52 and a cutting driver 53. The cutter head 51 is connected to the driving end of the cutting driver 53. The pad 52 is arranged corresponding to the cutter head 51. The pad 52 is located on the side of the photovoltaic film 40 away from the cutter head 51.

[0039] In this embodiment, the above structure realizes automatic cutting of the photovoltaic film 40 .

[0040] Further, such as Figure 1-3 The clamping assembly 6 shown includes a clamping driver 61 , an elastic telescopic rod 62 and a pressure roller 63 , wherein both ends of the pressure roller 63 are rotatably connected to the elastic telescopic rod 62 via a rotating shaft, and the other end of the elastic telescopic rod 62 is connected to the driving end of the clamping driver 61 .

[0041] In this embodiment, the above structure realizes compression of the photovoltaic film 40 to prevent the roll from unwinding and loosening after the roll loses its tension.

[0042] Further, such as Figure 1-3 The elastic telescopic rod 62 shown includes a sleeve rod 621 and a connecting rod 622 telescopically sleeved with the sleeve rod 621. A spring 623 is arranged inside the sleeve rod 621. The sleeve rod 621 is connected to the driving end of the clamping driver 61. The end of the connecting rod 622 away from the sleeve rod 621 is rotatably connected to the pressure roller 63.

[0043] In this embodiment, the above structure adopts an elastic pressing structure design, which can avoid damage to the surface of the photovoltaic film 40 caused by hard pressing while pressing the coil.

[0044] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
