[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Reference below Figure 1 The encapsulation device 100 according to an embodiment of the present invention is described.

[0027] The film wrapping device 100 according to the embodiment of the utility model is used for packaging box film wrapping, such as Figure 1 As shown, the film coating device 100 includes: a folding component and a film feeding component.

[0028] Specifically, the folding assembly includes a folding piece 11, which is suitable for being arranged on the upper side of the packaging box and contacting the film 60. The folding piece 11 includes a top surface portion 111 and a side folding portion 112. The top surface portion 111 is adapted to the top surface of the packaging box. The number of the side folding portions 112 is multiple, for example, the side folding portions 112 can be four, five or six, and the multiple side folding portions 112 can be rotatably connected to the outer peripheral edge of the top surface portion 111. The film conveying assembly is used to convey the film 60 between the packaging box and the folding piece 11.

[0029] It should be noted that the number of side folding portions 112 can correspond one-to-one to the edges of the top surface portion 111, and the number of side folding portions 112 can also be greater than the number of edges of the top surface portion 111, that is, the edge of one top surface portion 111 can be connected to multiple side folding portions 112. Therefore, when the size of the packaging box is large, the film 60 covering one side of the packaging box is folded through multiple side folding portions 112, so that the film 60 can be wrapped more evenly.

[0030] During the wrapping process, the packaging box is first moved under the folding piece 11, and then the film feeding assembly conveys the film 60 between the packaging box and the folding piece 11, and then the folding piece 11 and the film 60 are moved downward to the top surface of the packaging box, and the folding piece 11 and the film 60 are made to contact, and the top surface portion 111 is in contact with the top surface of the packaging box through the film 60, and then the side folding portion 112 is folded toward the packaging box, and the film 60 is folded toward the packaging box and wrapped on the packaging box under the drive of the side folding portion 112, thereby achieving the wrapping of the top and sides of the packaging box. At the same time, it can be understood that compared with manual wrapping, wrapping by the wrapping device 100 can improve the wrapping efficiency.

[0031] After one packaging is completed, the side folding edge portion 112 is folded away from the packaging box, and then the side folding edge portion 112 is moved upward to separate from the packaging box. After the packaging box is removed, the next packaging box can be packaged.

[0032] After the folding member 11 wraps the film 60 in the packaging box, the film 60 can be fixed on the packaging box by a binding rope, or by applying glue on the outer surface of the packaging box to fix the film 60 on the packaging box, or by hot-melt connection of the film 60 on adjacent sides of the packaging box to fix the film 60 on the packaging box. The above is only an example and is not intended to limit the present application.

[0033] During the transportation of the packaging box, the bottom of the packaging box is supported by a pallet bracket. When rain and snow fall on the packaging box, the film 60 wrapped on the top and sides of the packaging box can prevent the rain and snow from wetting the packaging box from the top and sides, and the pallet bracket can prevent the rain and snow from wetting the packaging box from the bottom of the packaging box, thereby meeting the rain and snow protection requirements of the packaging box.

[0034] According to the film wrapping device 100 of the embodiment of the utility model, the top surface and the side surface of the packaging box can be wrapped, thereby meeting the rain and snow protection requirements of the packaging box and improving the film wrapping efficiency.

[0035] In some embodiments of the present invention, Figure 1 As shown, the side folding portion 112 corresponds to the edge of the top surface portion 111 one by one, and the side folding portion 112 is provided with hot melt components 1121 on both sides of the circumferential edge of the top surface portion 111. After the side folding portion 112 folds the film 60 to cover the side of the packaging box, the hot melt component 1121 starts to heat to melt the film 60 at the connecting edge of the two adjacent sides of the packaging box, and stops heating after the set heating time, and then the melted film 60 gradually cools down. After the film 60 is cooled, the film 60 on the two adjacent sides of the packaging box can be connected, so that the film 60 can be set on the packaging box, thereby improving the rain and snow protection effect of the packaging box. Preferably, the hot melt component 1121 is a hot melt resistor.

[0036] In some embodiments of the present invention, Figure 1As shown, the folding member 11 is provided with a first suction cup 115, which is suitable for adsorbing the film 60. When the film feeding assembly conveys the film 60 to the bottom of the folding member 11, the first suction cup 115 adsorbs the film 60 so that the film 60 is attached to the folding member 11, and then the folding member 11 moves with the film 60 to the top surface of the packaging box, and then the packaging box is filmed, thereby improving the filming effect of the filming device 100 on the packaging box. After completing one filming, the first suction cup 115 cancels the adsorption of the film 60, and then the side folding portion 112 is folded in the direction away from the packaging box, and then the folding member 11 is lifted upward, and after the filmed packaging box is removed, the next packaging box can be filmed.

[0037] Preferably, the first suction cup 115 is a pneumatic suction cup, there are eight first suction cups 115 , there are four side folding portions 112 , and each side folding portion 112 is provided with two first suction cups 115 arranged at intervals at one end away from the top surface portion 111 .

[0038] In some embodiments of the present invention, Figure 1 As shown, the folding assembly further includes: a folding bracket 12, and the folding member 11 is movably arranged on the folding bracket 12. By providing the folding bracket 12, the folding bracket 12 can provide support for the folding member 11, so that the folding member 11 can move up and down relative to the packaging box more easily.

[0039] In some embodiments of the present invention, Figure 1 As shown, the folding assembly further includes: a first cylinder 113, which is connected to the folding member 11 to drive the folding member 11 to move up and down relative to the folding bracket 12. Thus, the folding member 11 can be moved up and down during the film coating process, wherein the cylinder-driven movement speed is faster and the cost is lower, thereby improving the film coating efficiency and reducing the production cost of the film coating device 100.

[0040] In some embodiments of the present invention, Figure 1 As shown, the folding assembly also includes: a drive motor 114, which is connected to the side folding portion 112 to drive the side folding portion 112 to rotate relative to the top surface portion 111, thereby realizing the automation of folding the side folding portion 112 during the wrapping process, wherein the drive motor 114 is sensitive to response and occupies a small volume, which is convenient for layout.

[0041] In some embodiments of the present invention, Figure 1 As shown, the film conveying assembly includes: a film conveying guide rail 21 and a film conveying member 22.

[0042] Specifically, the film feeding guide rail 21 is disposed below the folding member 11 , and the film feeding member 22 is movably disposed on the film feeding guide rail 21 . The film feeding member 22 is suitable for being connected to the extended end of the film sheet 60 wound on the reel 40 .

[0043] During the film wrapping process, after the packaging box moves to the bottom of the folding piece 11, the film feeding piece 22 drives the lead end of the film 60 to move toward the packaging box along the film feeding guide rail 21. After the film 60 moves between the packaging box and the folding piece 11, the first suction cup 115 on the folding piece 11 absorbs the film 60, and the film 60 detaches from the film feeding piece 22. Then the film feeding piece 22 returns to the initial position along the film feeding guide rail 21. In this way, the film feeding of the film feeding assembly can be realized, and the structure of the film feeding assembly is relatively simple.

[0044] In some embodiments of the present invention, Figure 1 As shown, the film wrapping device 100 also includes: a reel support 50, on which the reel 40 is supported. During the process of continuously pulling out the film sheet 60 on the reel 40, the reel 40 will be subjected to a force. By setting the reel support 50, support can be provided for the reel 40, so that the reel 40 can rotate and the film pulling can proceed normally.

[0045] In some embodiments of the present invention, Figure 1 As shown, the extended end of the film 60 is arranged on the film feeding guide rail 21 , the film feeding member 22 is arranged on the lower side of the extended end of the film 60 , and the film feeding member 22 is provided with a second suction cup, which is suitable for adsorbing the film 60 .

[0046] During the film wrapping process, when the packaging box moves to the bottom of the folding member 11, the second suction cup on the film feeding member 22 absorbs the film sheet 60 from the bottom of the film sheet 60, and then the film feeding member 22 drives the film sheet 60 to move toward the packaging box. After the film sheet 60 moves between the packaging box and the folding member 11, the first suction cup 115 on the folding member 11 absorbs the film sheet 60, and the second suction cup on the film feeding member 22 cancels the absorption of the film sheet 60, so that the film sheet 60 is separated from the film feeding member 22, and then the film feeding member 22 returns to the initial position along the film feeding guide rail 21. Preferably, the second suction cup is a pneumatic suction cup, and there are two second suction cups, which are arranged at intervals on the film feeding member 22.

[0047] Among them, the protruding end of the film 60 is arranged on the film feeding guide rail 21. When the film 60 moves, the film feeding guide rail 21 can support and guide the film 60, so that the film 60 can maintain the unfolded shape when it moves to the top of the packaging box, and when the film feeding member 22 returns to the initial position, the relative position of the film feeding member 22 and the film 60 does not change, so that the circulating film can be carried out normally.

[0048] In some embodiments of the present invention, Figure 1As shown, a limiting fold 211 is formed at one end of the film feeding guide rail 21 away from the reel 40, and the limiting fold 211 is suitable for abutting against the film feeding member 22. By providing the limiting fold 211, the limiting fold 211 can prevent the film feeding member 22 from detaching from the film feeding guide rail 21, thereby improving the reliability of the film coating device 100 during operation.

[0049] In some embodiments of the present invention, Figure 1 As shown, the film wrapping device 100 further includes: a shearing member 30, which is arranged between the folding member 11 and the reel 40, and is suitable for shearing the film 60. After the film feeding member 22 drives the film 60 to move above the packaging box, the second suction cup on the film feeding member 22 cancels the adsorption of the film 60, and the first suction cup 115 adsorbs the film 60 onto the folding member 11, and then the shearing member 30 shears the film 60 from the reel 40, and then the film feeding member 22 returns to the initial position, at which time, the lead end of the film 60 is still located above the film feeding member 22, so that the next film wrapping can be performed. By setting the shearing member 30, the automation of shearing can be achieved.

[0050] In some embodiments of the present invention, Figure 1 As shown, the shearing piece 30 includes a shearing support 31 and a hot-melt shearing portion 32 .

[0051] Specifically, the shear bracket 31 is mounted on the extended end of the membrane 60 , and the hot melt shear portion 32 is movably disposed on the shear bracket 31 up and down, and the hot melt shear portion 32 is suitable for contacting with the membrane 60 .

[0052] When the film 60 needs to be sheared, the hot melt shearing portion 32 moves downward to contact the film 60. At the same time, the temperature of the hot melt shearing portion 32 rises to melt the film 60 in contact, thereby shearing the film 60. After the shearing is completed, the hot melt shearing portion 32 stops heating and moves upward to the initial position. By providing the shearing bracket 31 and the hot melt shearing portion 32, the shearing function of the shearing piece 30 can be realized. Preferably, the hot melt shearing portion 32 is a hot melt resistor.

[0053] In some embodiments of the utility model, the shearing piece 30 also includes: a second cylinder, which is connected to the hot melt shearing part 32 to drive the hot melt shearing part 32 to move up and down, thereby realizing the automatic movement of the hot melt shearing part 32 on the shearing bracket 31, wherein the cylinder-driven movement speed is faster and the cost is lower, thereby improving the coating efficiency and reducing the production cost of the coating device 100.

[0054] Reference below Figure 1 A specific embodiment of the present invention is described.

[0055] The film wrapping device 100 includes a folding assembly, a film feeding assembly and a shearing member 30 .

[0056] The folding assembly includes a folding member 11 , a folding bracket 12 and a first cylinder 113 .

[0057] The folding piece 11 is arranged on the folding bracket 12, and the first cylinder 113 is connected to the folding piece 11 to drive the folding piece 11 to move up and down. The folding piece 11 includes a top surface portion 111 and a side folding portion 112. The top surface portion 111 is rectangular, and there are four side folding portions 112. The four side folding portions 112 are rotatably connected to the four edges of the top surface portion 111 respectively. Four driving motors 114 are also arranged on the top surface portion 111. The driving motors 114 are connected to the side folding portions 112 to drive the side folding portions 112 to rotate relative to the top surface portion 111. The side folding portions 112 are provided with hot melt parts 1121 on two edges in the circumferential direction of the top surface portion 111, and the end of the side folding portion 112 away from the top surface portion 111 is provided with two first suction cups 115 arranged at intervals.

[0058] The film conveying assembly includes: a film conveying guide rail 21 and a film conveying member 22 .

[0059] The film feeding guide rail 21 is arranged below the folding member 11, and the film feeding member 22 is movably arranged on the film feeding guide rail 21. The film feeding member 22 is connected to the protruding end of the film sheet 60 wound on the reel 40. The reel 40 is supported on the reel bracket 50, and the reel bracket 50 is arranged at one end of the film feeding guide rail 21. The protruding end of the film sheet 60 is arranged on the film feeding guide rail 21. The film feeding member 22 is arranged below the protruding end of the film sheet 60. Two second suction cups are arranged at intervals on the film feeding member 22, and a limited folding edge 211 is formed at the end of the film feeding guide rail 21 away from the guide rail.

[0060] The shearing piece 30 includes: a shearing bracket 31, a hot melt shearing part 32 and a second cylinder. The shearing bracket 31 is mounted on the protruding end of the diaphragm 60, and the hot melt shearing part 32 is arranged on the shearing bracket 31. The second cylinder and the hot melt shearing part 32 drive the hot melt shearing part 32 to move up and down on the shearing bracket 31.

[0061] The coating process of the coating device 100 will be described below.

[0062] The packaging box is transported to the bottom of the folding piece 11 through the conveyor line, and then the second suction cup on the film feeding piece 22 absorbs the lead end of the film 60 and drives the film 60 to move along the film feeding guide rail 21 toward the packaging box. When the film 60 moves between the packaging box and the folding piece 11, the second chassis stops adsorbing the film 60, and the first suction cup 115 absorbs the film 60 onto the folding piece 11. Then the second cylinder drives the hot melt shearing part 32 to move downward and heat the film 60 to cut the film 60. Then the second cylinder drives the hot melt shearing part 32 to rise, and the film feeding piece 22 returns to its initial position.

[0063] Then, the first cylinder 113 drives the folding piece 11 to move downward to the top surface of the packaging box, and the top surface portion 111 contacts the top surface of the packaging box to wrap the film 60 on the top surface of the packaging box. Then, the driving motor 114 drives the side folding portion 112 to fold toward the packaging box. After the side folding portion 112 is folded into place, the hot melt component 1121 starts to heat to melt the film 60 at the connecting edge of the two adjacent sides of the packaging box. After the heating set time, the heating is stopped, and then the melted film 60 gradually cools down. After the film 60 is cooled, the film 60 on the two adjacent sides of the packaging box can be connected. Then, the first suction cup 115 cancels the adsorption of the film 60, and the driving motor 114 drives the side folding portion 112 to fold toward the initial position. The first cylinder 113 drives the folding piece 11 to move upward to the initial position, and then the film-wrapped packaging box is removed.

[0064] Thus, during the process of wrapping a packaging box once, the above process can be repeated to wrap multiple packaging boxes.
