[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The terms "first" and "second" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise expressly specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.

[0030] This application provides a packaging device, such as Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of an embodiment of the packaging device of this application; Figure 2 yes Figure 1A schematic diagram of the film liner handling mechanism. The packaging device 10 is used to package products using the film liner 20.

[0031] The film liner 20 includes a film (not shown) and a cardboard (not shown) stacked together. Specifically, the film is pasted onto one side of the cardboard along its stacking direction. When the packaging device 10 uses the film liner 20 to package the product, the stacking direction of the film liner 20 is parallel to the gravity direction X3. In the following text, when positioning is mentioned based on the stacking direction, it is assumed that the stacking direction is parallel to the gravity direction X3.

[0032] Before the film liner 20 is used to pre-package the product, the packaging device 10 pre-treats the film liner 20 so that the film in the middle part of the film liner 20 is separated from the corresponding part of the cardboard along the stacking direction to form a receiving space for accommodating the product with openings at both ends (here, the two ends refer to any two oppositely arranged ends on the film liner 20 perpendicular to the stacking direction).

[0033] The packaging device 10 includes an adjustment mechanism 100 and a product handling mechanism 200.

[0034] The adjustment mechanism 100 is used to adjust the shape of the accommodating space of the film liner 20 based on the shape of the product, so that the shape of the adjusted accommodating space matches the shape of the product, and to complete the pre-packaging of the product.

[0035] The product handling mechanism 200 is used to transport the product into the receiving space along the loading direction X1. The loading direction X1 is the direction in which the product is loaded into the receiving space, which is perpendicular to the opening of the receiving space, that is, parallel to the opening direction of the receiving space.

[0036] Specifically, the product handling mechanism 200 is arranged on one side of the adjustment mechanism 100 along the loading direction X1. The adjustment mechanism 100 adjusts the opening of the accommodating space so that the shape of the opening of the accommodating space matches the shape of the product. This ensures that the product handling mechanism 200 will not touch the film when it moves the product to the accommodating space along the loading direction X1, thereby causing the film and cardboard to lose their adhesion and fall off completely. This effectively improves the pass rate of the products packaged by the packaging device 10 using the film liner 20.

[0037] Unlike existing technologies, a packaging device 10 is provided for packaging products using a film liner 20. The film liner 20 comprises stacked film and cardboard. The packaging device 10 includes an adjustment mechanism 100 and a product transport mechanism 200. The adjustment mechanism 100 adjusts the shape of the accommodating space between the film and cardboard based on the shape of the product, ensuring the adjusted shape matches the product shape and completing the pre-packaging. The product transport mechanism 200 is located on one side of the adjustment mechanism 100 and transports the product into the accommodating space. Through this embodiment, when packaging products using the film liner 20, the packaging device 10 can adjust the shape of the accommodating space of the film liner 20 based on the product shape using the adjustment mechanism 100, ensuring the shape of the accommodating space matches the product shape. This prevents the product transport mechanism 200 from being interfered with by the film when transporting the product into the accommodating space, effectively guaranteeing the success rate of pre-packaging and thus significantly improving the packaging qualification rate.

[0038] Optionally, the packaging device 10 may also include a film liner transport mechanism 300.

[0039] The film liner conveying mechanism 300 is used to pre-process the film liner 20, that is, to pre-fold the film liner 20 so that the film of the film liner 20 is separated from the cardboard part to form a receiving space, and is also used to convey the pre-folded film liner 20 to the adjusting mechanism 100.

[0040] Specifically, the film liner transport mechanism 300 is located on the other side of the adjustment mechanism 100, that is, on the side opposite to the product transport mechanism 200.

[0041] When the film liner 20 is located on the film liner conveying mechanism 300, the film of the film liner 20 is positioned below the cardboard along the gravity direction X3. During the pre-processing of the film liner 20, the film liner conveying mechanism 300 bends (i.e., pre-folds) the opposite edges of the film liner 20. This causes the middle portion of the film on the bent sides of the film liner 20 to detach from the cardboard due to gravity, thus forming an accommodating space with openings at both ends. This process effectively prevents the film from delaminating when it separates from the cardboard. For example, in some cases, mechanically pulling the film can partially separate it from the cardboard, but due to the uncontrollability of mechanical pulling, delamination can easily occur. In contrast, using gravity to detach the film from the cardboard effectively allows the film to naturally separate from the cardboard.

[0042] Optional, such as Figure 2As shown, the film liner handling mechanism 300 includes a frame 310, a second gripper 320, a fourth transport mechanism 330, a fifth transport mechanism 340, a support 360, a motor 370, and a motor 380.

[0043] The second gripper 320 is used to grip the film liner 20 and perform a pre-folding operation on it.

[0044] Optionally, the second gripper 320 includes a second suction cup 321 and a folding mechanism 322 symmetrically arranged on opposite sides of the second suction cup 321. The second suction cup 321 is a U-shaped structure with its opening facing the adjustment mechanism 100, and it has an adsorption function to adsorb the side of the cardboard away from the film, thereby gripping the film liner 20. The folding mechanism 322 is a bending mechanism, symmetrically arranged on both sides of the U-shaped second suction cup 321 parallel to the input direction, for folding the opposite sides of the film liner 20 adsorbed on the second suction cup 321, thereby pre-folding the film liner 20.

[0045] The fourth transport mechanism 330 is used to transport the pre-folded film liner 20 to the adjusting mechanism 100. The fourth transport mechanism 330 can transport the pre-folded film liner 20 to the corresponding position in the adjusting mechanism 100 along a direction opposite to the loading direction X1. The fourth transport mechanism 330 employs a lead screw transmission mechanism (not shown) with high linear motion accuracy and driven by a motor 370. In other embodiments, the fourth transport mechanism 330 can also be other transport mechanisms with high transmission accuracy.

[0046] The fifth transport mechanism 340 is provided with a transport plane for transporting the film liner 20 in a direction opposite to the loading direction X1 to the gripping position of the first gripping device. The fifth transport mechanism 340 is a belt transport mechanism driven by a motor 380. In other embodiments, the fifth transport mechanism 340 may also employ other types of transport mechanisms, which will not be detailed here.

[0047] Specifically, the fifth transport mechanism 340 is fixedly mounted on the upper surface of the frame 310 along the gravity direction X3. The fourth transport mechanism 330 is mounted on one side of the support 360, wherein the other side of the support 360 opposite to the side where the fourth transport mechanism 330 is mounted is fixedly connected to the upper surface of the frame 310 and spans above the fifth transport mechanism 340, so that the fourth transport mechanism is suspended above the fifth transport mechanism. The fourth transport mechanism 330 is connected to the second suction cup 321, wherein the fourth transport mechanism 330 can be connected to the second suction cup 321 through a telescopic mechanism (not shown) that can extend and retract along the stacking direction, so that the second gripper 320 is suspended between the fourth transport mechanism 330 and the fifth transport mechanism 340.

[0048] In this case, the direction of the transport film liner 20 of the fifth transport mechanism 340 on the transport plane is opposite to the loading direction X1. The film is located between the transport plane and the cardboard along the stacking direction of the cardboard and the film. The transport plane is perpendicular to the stacking direction, that is, when the film liner 20 is transported on the transport plane, the film is located below the cardboard.

[0049] The fifth transport mechanism 340 transports the film liner 20 to the gripping position of the second gripper 320, and the fourth transport mechanism 330 moves the second suction cup 321 to the gripping position of the film liner 20, that is, transports the second suction cup 321 to the gripping position of the second gripper 320. The second suction cup 321 adheres to the side of the cardboard away from the film to fix the film liner 20 thereon. Further, the telescopic mechanism raises the second suction cup 321 with the film liner 20 fixed thereon, and the fourth transport mechanism 330 transports the second suction cup 321 to the pre-folding position. Then, the folding mechanism 322 pre-folds the film liner 20, and then transports the film liner 20 to the adjusting mechanism 100, where the adjusting mechanism 100 performs the next step of processing on the film liner 20.

[0050] It is worth noting that the gripping position, pre-folding position, and adjustment mechanism 100 of the second gripper 320 are located on the same straight line. That is, the gripping position, pre-folding position, and adjustment mechanism 100 are located on a transport direction X2 that is parallel to and opposite to the loading direction X1. The transport direction X2 refers to the direction in which the fourth transport mechanism 330 and the fifth transport mechanism 340 transport the film liner 20. With this arrangement, when the fourth transport mechanism 330 transports the film liner 20, it can quickly transport the film liner 20 to the adjustment mechanism 100 in a direction opposite to the loading direction X1, thereby effectively improving the transport efficiency of the film liner handling mechanism 300, and thus effectively improving the packaging efficiency of the packaging device 10.

[0051] Optionally, the film liner 20 conveying device may also include a film liner positioning mechanism 350.

[0052] The film liner positioning mechanism 350 is symmetrically arranged on both sides of the transport plane along the transport direction X2 of the film liner 20 (both sides of the transport plane refer to the sides perpendicular to the transport direction X2 and the stacking direction), and is located after the film liner 20 along the transport direction X2. The film liner positioning mechanism 350 includes two push plates (not shown in the figure) symmetrically arranged on the transport plane and a drive mechanism 390 driven by the push plates. The drive mechanism 390 drives the two opposing push plates to move closer together in a direction perpendicular to the transport direction X2, thereby adjusting the relative position of the film liner 20 after it has passed through the film liner positioning mechanism 350.

[0053] The film liner positioning mechanism 350 is used to adjust the relative position of the film liner 20 on the transport plane. For example, if the shape of the film liner 20 is positive, after adjustment by the film liner positioning mechanism 350, the opposite two sides of the film liner 20 are parallel to the transport direction X2, ensuring that the opening direction of the opening is perpendicular to the other pair of opposite sides of the film liner 20. This opening is the opening through the accommodating space of the folded film liner 20. It is worth noting that in other embodiments, the film liner positioning mechanism 350 may also be composed of other mechanisms, which will not be described in detail here.

[0054] Optional, such as Figure 3 As shown, Figure 3 yes Figure 1 A schematic diagram of the adjustment mechanism. The adjustment mechanism 100 includes a first fixing member 110, a second fixing member 120, a driving member (not shown), a support mechanism 130, and a rotating frame 140.

[0055] When the adjusting mechanism 100 adjusts the accommodating space of the film liner 20, the first suction cup has a disc-shaped structure with an adsorption hole on the side near the first fixing member 110. The adsorption hole facilitates the fixing function. The first fixing member 110 is used to fix the cardboard so that the film liner 20 is suspended. The first fixing member 110 is an adsorption member with an adsorption function. When the film liner transport mechanism 300 transports the film liner 20 to the adjusting mechanism 100, the first fixing member 110 passes through the U-shaped notch of the second suction cup 321. After the second suction cup 321 adsorbs the cardboard, the second suction cup 321 detaches from the cardboard and returns along the original path by the drive of the fourth transport mechanism 330, and transports the next film liner 20.

[0056] The second fixing member 120 is used to adsorb the film to adjust the shape of the accommodating space. In other words, the second fixing mechanism is used to adjust the cross-sectional shape of the accommodating space perpendicular to the loading direction X1 (and the cross-sectional shape of the opening of the accommodating space) so that the cross-sectional shape of the product perpendicular to the loading direction X1 matches the cross-sectional shape of the accommodating space perpendicular to the loading direction X1, and the cross-sectional area of ​​the product perpendicular to the loading direction X1 is smaller than the cross-sectional area of ​​the accommodating space perpendicular to the loading direction X1.

[0057] Optionally, the second fixing member 120 includes a first suction cup (not shown in the figure) and an adjusting member (not shown in the figure). The first suction cup is provided with a plurality of suction holes on one side for adsorbing the film. The adjusting member is connected to the suction holes and is used to control the opening of the corresponding suction holes based on the shape of the product, so as to adjust the size of the opening of the accommodating space along the loading direction X1 and the size along the stacking direction of the cardboard and the film.

[0058] Specifically, based on the different shapes and sizes of the products, the size of the opening of the accommodating space along the loading direction X1 and along the stacking direction of the cardboard and the film can be adjusted by controlling the number of connecting parts and adsorption holes.

[0059] The driving component is connected to the first fixing member 110 and / or the second fixing member 120, and is used to drive the first fixing member 110 and / or the second fixing member 120 to move along the stacking direction of the cardboard and the film, so as to adjust the distance between the film and the cardboard for pre-packaging of the product. Optionally, the driving component is connected to the first fixing member 110 and / or the second fixing member 120 through a telescopic member (not shown) that extends and retracts along the stacking direction. The driving component drives the telescopic member, thereby driving the first fixing member 110 and / or the second fixing member 120 to move along the stacking direction. It is worth noting that in other embodiments, the first fixing member 110 and / or the second fixing member 120 can also be connected to the driving component through a transmission member of other forms, thereby realizing the adjustment of the relative position between the first fixing member 110 and the second fixing member 120.

[0060] The rotating frame 140 is equipped with a rotating shaft, which is rotatably connected to the support mechanism 130. The rotating frame 140 can rotate relative to the support mechanism 130 around the rotating shaft, and the rotation direction of the rotating shaft is in the same plane as the stacking direction of the cardboard and the film. The support mechanism 130 is also equipped with a drive mechanism 150, which is connected to the rotating frame 140 for driving its rotation. The drive mechanism 150 is a motor; in other embodiments, it can be other driving components. The first fixing member 110 and the second fixing member 120 are disposed on the rotating frame 140. When the rotating frame 140 rotates around the rotating shaft, the relative positions of the first fixing member 110 and the second fixing member 120 along the stacking direction change accordingly. Therefore, by controlling the rotation of the rotating frame 140 around the rotating shaft, the relative positions of the cardboard and the film along the stacking direction are adjusted, so that the pre-packaged product placed in the film liner 20 can be easily transported by the product handling mechanism 200.

[0061] Optional, such as Figure 4 As shown, Figure 4 yes Figure 1 A schematic diagram of the assembly structure of the adjustment mechanism and the product handling mechanism. The product handling mechanism 200 includes a first gripper 210, a first transport mechanism 220, a second transport mechanism 230, a third transport mechanism 240, a body 250, and a support 260.

[0062] The first gripper 210 is used to grip the product. The first gripper 210 includes a jaw (not shown) and a drive device (not shown) connected to the jaw. The drive device controls the opening and closing of the jaw, enabling the jaw to perform gripping and dropping operations. It is worth noting that the first gripper 210 can be configured based on the shape of the product to facilitate product gripping; it is not limited to the jaw form, which will not be elaborated upon here.

[0063] The first transport mechanism 220 is connected to the first gripper 210 and is used to transport the product gripped by the first gripper 210 to the receiving space. The first transport mechanism 220 adopts a lead screw transmission mechanism (not shown) with high linear motion accuracy and driven by a motor (not shown). In other embodiments, the first transport mechanism 220 may also be other transport mechanisms with high transmission accuracy.

[0064] The second transport mechanism 230 is used to transport the product to the gripping position corresponding to the first gripper 210. The first transport mechanism 220 is a belt conveyor (not shown in the figure), which is driven by a motor (not shown in the figure). In other embodiments, the fourth transport mechanism 330 may also be other types of transport mechanisms, which will not be described in detail here.

[0065] The first gripper 210 is also used to grip the pre-packaged product. The first transport mechanism 220 transports the pre-packaged product gripped by the first gripper 210 to the third transport mechanism 240, which transports the pre-packaged product to the packaging location. The third transport mechanism 240 is a belt conveyor (not shown in the figure), driven by a motor (not shown in the figure). Depending on the shape of the product or the transport precision, other types of transport mechanisms may be used for the third transport mechanism 240 in other embodiments, which will not be detailed here.

[0066] Specifically, the second transport mechanism 230 and the third transport mechanism 240 are spaced apart on the upper surface of the body 250 along the loading direction X1. One side of the bracket 260 is positioned between the second transport mechanism 230 and the third transport mechanism 240 and is connected and fixed to the upper surface of the body 250. The other side of the bracket 260 spans above the second transport mechanism 230 and extends along the loading direction X1 to the adjustment mechanism 100. The first transport mechanism 220 is mounted on the other side of the bracket 260. The first gripper 210 is connected to the first transport mechanism 220 via a telescopic member (the telescopic member can control the first gripper to extend and retract up and down along the gravity direction X3). Driven by the first transport mechanism 220, the first gripper 210 can move between its gripping position and its dropping position, loading the product into the accommodating space and transporting the pre-packaged product to the dropping position of the first gripper 210. The first gripper 210 lands at a position corresponding to the transport plane of the second transport mechanism 230. The first gripper 210 lands at a position corresponding to the transport plane of the third transport mechanism 240.

[0067] It is worth noting that the drive device in the first gripper 210 can also control the gripper to rotate around its rotation axis (here, the rotation axis refers to the rotation axis of the gripper, which is parallel to the direction of gravity) to adjust the orientation of the gripper, so that the first transport mechanism 220 can drive the first gripper 210 to a position suitable for the first gripper 210 to drop the object with a relatively short stroke, thereby effectively reducing the length of the bracket 260 and the lead screw mechanism, thus saving manufacturing costs.

[0068] The opening of the accommodating space, the dropping position of the first gripper 210, and the dropping position of the first gripper 210 are all located on the same straight line along the loading direction X1, so that the first transport device can quickly load the product into the accommodating space along the loading direction X1 and transport the pre-packaged product back to the third transport mechanism 240. The third transport mechanism 240 then transports the product to the packaging position for packaging, thereby effectively improving the product packaging efficiency.

[0069] This application proposes a packaging method, such as Figure 5 As shown, Figure 5 yes Figure 1 A schematic flowchart of an embodiment of a packaging method using a packaging apparatus. The method is used to package a product using a film liner 20, which includes stacked films and cardboard. The packaging method includes steps S100 to S200.

[0070] Step S100: Adjust the shape of the accommodating space between the film and the cardboard based on the shape of the product, so that the shape of the adjusted accommodating space matches the shape of the product.

[0071] The film liner 20 conveying device separates the film in the film liner 20 from the paperboard located between opposite sides to form a receiving space with two opposite openings, and the opening direction of the openings is opposite to and parallel to the product loading direction X1.

[0072] The adjustment mechanism 100, based on the shape of the product, controls the corresponding adsorption holes on the first suction cup to be open through the adjustment component, so that the adsorption holes at the corresponding positions adsorb the film at the corresponding positions. The driving component adjusts the distance between the first fixing component 110 and the second fixing component 120, thereby changing the shape of the accommodating cavity opening. That is, it adjusts the size of the accommodating space along the loading direction X1 and the size along the stacking direction of the cardboard and the film, so that the size of the cross-sectional shape of the accommodating space along the loading direction X1 is larger than the cross-sectional shape of the product along the loading direction X1, and ensures that when the product is loaded into the accommodating space along the loading direction X1, the side of the cross-sectional shape of the accommodating space along the loading direction X1 will not interfere with the product. For example, if the cross-sectional shape of the product along the loading direction X1 is rectangular, the adjustment mechanism 100 controls the adsorption hole at the corresponding position on the first suction cup to be open, thereby making the side of the accommodating space near the first suction cup larger than the long side of the rectangle. At the same time, the distance between the first fixing member 110 and the second fixing member 120 is adjusted by the driving member, thereby ensuring that each side of the product will not interfere with the film when it is loaded into the accommodating space along the loading direction X1.

[0073] Among them, such as Figure 6 As shown, Figure 6 This is a schematic flowchart of an embodiment of a film liner handling mechanism for pre-treating the film liner. Before adjusting the shape of the accommodating space between the film and the cardboard based on the shape of the product, the accommodating space between the film and the cardboard can be achieved through steps S110 to S120.

[0074] Step S110: Pre-fold the film liner 20 to separate the film from the cardboard portion of the film liner 20 to form an accommodating space.

[0075] The film liner handling mechanism 300 pre-processes the film liner 20. Specifically, the fifth transport mechanism 340 of the film liner handling mechanism 300 transports the film liner 20 to the gripping position of the second gripper 320 along the transport direction X2. The second gripper 320 picks up the film liner 20 from the transport plane and connects the second gripper 320 and the pre-folding position to which the film liner 20 has been transported via the fourth transport mechanism 330. After reaching the pre-folding position, the second gripper 320 folds the two opposite sides of the film liner 20 adsorbed on the second suction cup 321 through the folding mechanism 322 to achieve pre-folding of the film liner 20. This causes the film in the middle part of the bent sides of the film liner 20 to detach from the cardboard due to gravity, thereby forming an accommodating space with openings at both ends.

[0076] Step S120: The pre-folded film liner 20 is transported to the adjustment mechanism 100.

[0077] After being pre-folded, the film liner 20 is transported by the fourth transport mechanism 330 along the transport direction X2 to the adjustment mechanism 100. The adjustment mechanism 100 adjusts the distance between the first fixing member 110 and the second fixing member 120 so that the film liner 20 does not interfere with the first fixing member 110 and the second fixing member 120 when it is transported to the corresponding position.

[0078] Furthermore, the film liner transport mechanism 300 transports the film liner 20 between the first fixing member 110 and the second fixing member 120 via the fourth transport mechanism 330. The first gripper 210 adsorbs the cardboard to fix the film liner 20. After the adjustment mechanism 100 determines that the first gripper 210 has fixed the film liner 20, the second gripper 320 disconnects the air passage and disengages from the film liner 20, and returns to the gripping position of the second gripper 320 along the loading direction X1 to grip another film liner 20.

[0079] Step S200: Place the product into the adjusted storage space and pre-package the product.

[0080] First, the product handling mechanism 200 picks up the product from the gripping position of the first gripper 210 and slowly loads the product into the adjusted accommodating space along the loading direction X1.

[0081] Furthermore, the adjustment mechanism 100 adjusts the spacing between the first fixing member 110 and the second fixing member 120 along the stacking direction through the driving member, thereby adjusting the distance between the cardboard and the film along the stacking direction so that the product contacts the cardboard and the film on both sides along the stacking direction, thereby achieving pre-packaging.

[0082] Unlike existing technologies, our invention uses an adjustment mechanism 100 to adjust the shape of the accommodating space of the film liner 20 based on the shape of the product, so that the product will not interfere with the film when it is installed in the accommodating space.

[0083] like Figure 7 As shown, Figure 7 yes Figure 1 A schematic flowchart of another embodiment of a packaging method using a packaging apparatus. The packaging method includes steps S300 to S600.

[0084] Step S300: Adjust the shape of the accommodating space between the film and the cardboard based on the shape of the product, so that the shape of the adjusted accommodating space matches the shape of the product.

[0085] The specific implementation methods are as described in the above embodiments, and will not be repeated here.

[0086] Step S400: Place the product into the adjusted storage space and pre-package the product.

[0087] The specific implementation methods are as described in the above embodiments, and will not be repeated here.

[0088] Step S500: Adjust the relative position of the film liner used for pre-packaging along the stacking direction.

[0089] After pre-packaging, the product is wrapped between the film and the cardboard. The adjusting mechanism 100 drives the rotating frame 140 to rotate 180° around the rotating axis so that the positions of the cardboard and the film are interchanged along the stacking direction, so that the cardboard is located below the film. Furthermore, based on the cardboard being located below, the first gripper can transport the film liner 20 containing the product to the third transport mechanism 240 by means of carrying, thereby effectively solving the problem of inconvenience in gripping the film liner 20 containing the product, and thus effectively preventing the product from falling out of the film liner 20 during transportation.

[0090] Step S600: Transport the pre-packaged product to the packaging location.

[0091] The product handling mechanism 200 transports the processed products to the third transport mechanism 240 via the first gripper 210 and the second transport mechanism 230. The third transport mechanism 240 then transports the pre-packaged products to the packaging location for complete packaging, thus completing the entire packaging process.

[0092] Specifically, the first gripper 210, with its claws inserted into the bottom of the cardboard, picks up the pre-packaged product. The first transport mechanism 220, moving in the opposite direction of the loading direction X1, drives the first gripper 210 to the corresponding position. Then, the drive device rotates the claws 180° so that the product is positioned directly above the dropping point. Further, the telescopic component lowers the first gripper 210 along the gravity direction X3, thus completing the dropping operation.

[0093] In summary, the packaging device 10 of this application pre-folds the film liner 20 by means of the film liner transport mechanism 300, so that the film liner 20 partially separates from the cardboard by gravity to form a storage space, thereby effectively solving the problem that the film is prone to delamination and loss of stickiness when separating the film.

[0094] Furthermore, the adjustment mechanism 100 of this application includes a first fixing member 110 and a second fixing member 120. The first suction cup on the two fixing members is provided with multiple suction holes. The adjustment mechanism 100 controls the opening of the suction holes at the corresponding positions based on the shape of the product, so that the shape of the accommodating space matches the product. This ensures that when the packaging device 10 uses the film liner 20 to package products of different shapes and sizes, the products will not interfere with the film, thereby effectively improving the packaging capacity of the packaging device 10 for various products and effectively improving the user's packaging efficiency.

[0095] Furthermore, the product handling device of this application also includes a second transport mechanism 230 and a third transport mechanism 240. The second transport mechanism 230 can efficiently transport the product to the gripping position of the first gripper 210, and the third transport mechanism 240 can quickly transport the pre-packaged product to the product packaging position, thereby effectively improving the product packaging efficiency.
