[0034] like Figure 1As shown, this application embodiment provides a packaging liner 10, including a cushioning plate 11 and a highly elastic film 12 disposed on the front side of the cushioning plate 11. The cushioning plate 11 is provided with a transverse crease 111 and a longitudinal crease 112. The highly elastic film 12 extends across the transverse crease 111 and its two ends are respectively connected to the two longitudinal ends of the cushioning plate 11. In use, the packaged item can be placed between the highly elastic film 12 and the cushioning plate 11, and then the packaged item can be packaged by folding the cushioning plate 11.

[0035] like Figures 2 to 8 As shown, this application embodiment also provides an automatic forming device for packaging pads 10, suitable for placing packaged items between a high-elasticity film 12 and a cushioning plate 11 and folding the cushioning plate 11 to achieve packaging of the packaged items. The automatic forming device includes a frame and a feeding module 1, a first folding forming module 2, and a second folding forming module 3 disposed on the frame. The feeding module 1 is used to feed the packaging pad 10 to the first folding forming module 2 and to lift the high-elasticity film 12 to form an accommodating space between it and the cushioning plate 11. The first folding forming module 2 is used to fold the longitudinal ends of the cushioning plate 11 along the transverse creases 111 to the back of the cushioning plate 11 to stretch the high-elasticity film 12 to wrap the packaged items. The second folding forming module 3 is used to fold the transverse ends of the cushioning plate 11 along the longitudinal creases 112 to both sides of the packaged items.

[0036] Optionally, the feeding module 1 includes a hopper 1.1 and a conveying mechanism 1.2. The hopper 1.1 is located on one side of the first folding and forming module 2, and the hopper 1.1 stores packaging pads 10. The conveying mechanism 1.2 is located between the hopper 1.1 and the first folding and forming module 2, and is used to convey the packaging pads 10 in the hopper 1.1 to the first folding and forming module 2.

[0037] Optionally, the hopper 1.1 includes a main board 1.1.1, a long side plate 1.1.2, and a short side plate 1.1.3. The long side plate 1.1.2 is mounted on the side of the main board 1.1.1. The short side plate 1.1.3 is mounted on the side of the long side plate 1.1.2. The main board 1.1.1, the long side plate 1.1.2, and the short side plate 1.1.3 together form a storage space. In addition, the upper end of the hopper 1.1 can form a hopper opening that communicates with the storage space.

[0038] Optionally, the main board 1.1.1 and the long side plate 1.1.2 are provided with slots, which are oblong holes arranged in the horizontal direction. For ease of description, the slot on the main board 1.1.1 is defined as the first slot 1.1.1.1, and the slot on the long side plate 1.1.2 is defined as the second slot 1.1.2.1. In specific settings, the long side plate 1.1.2 is bolted into the first slot 1.1.1.1, and the short side plate 1.1.3 is bolted into the second slot 1.1.2.1. By adjusting the position of the long side plate 1.1.2 in the first slot 1.1.1.1 and the position of the short side plate 1.1.3 in the second slot 1.1.2.1, the size of the storage space can be adjusted, so that the hopper 1.1 can be used to store packaging liners 10 of different specifications.

[0039] Optionally, the hopper 1.1 is equipped with a rack 1.1.4, a lifting assembly, and a position detector 1.1.8. The rack 1.1.4 is vertically movably mounted within the hopper 1.1 and is used to deliver the packaging pad 10 to a specified height. The lifting assembly is mounted within the hopper 1.1 and connected to the rack 1.1.4, and is used to control the lifting and lowering of the rack 1.1.4. The position detector 1.1.8 is mounted on the side of the hopper 1.1 and electrically connected to the lifting assembly, and is used to detect whether the packaging pad 10 has reached the specified height, so that the lifting assembly controls the lifting and lowering of the rack 1.1.4 when the packaging pad 10 has not reached the specified height.

[0040] Optionally, the lifting assembly includes a first lead screw 1.1.5, a first linear guide rail 1.1.6, and a first servo motor 1.1.7. The first lead screw 1.1.5 is rotatably mounted inside the main board 1.1.1 along the height direction, and the material rack 1.1.4 is sleeved on the outside of the first lead screw 1.1.5. The first linear guide rail 1.1.6 is mounted inside the main board 1.1.1 and parallel to the first lead screw 1.1.5, with the material rack 1.1.4 and the first linear guide rail 1.1.6 in sliding engagement. The first servo motor 1.1.7 is mounted inside the main board 1.1.1 and connected to the first lead screw 1.1.5. In practical use, when the first servo motor 1.1.7 is started, it can drive the first lead screw 1.1.5 to rotate, causing the material rack 1.1.4 to move along the first linear guide rail 1.1.6, thereby realizing the lifting and lowering of the material rack 1.1.4.

[0041] Optionally, the positioning detector 1.1.8 is a photoelectric sensor. For example, the photoelectric sensor includes a light signal transmitter and a light signal receiver, which are respectively located on opposite sides of the hopper 1.1. When the light signal receiver can receive the light signal emitted by the light signal transmitter, there is no packaging pad 10 between them, that is, the packaging pad 10 has not reached the specified height. At this time, the lifting assembly can control the rack 1.1.4 to continue rising. When the light signal receiver cannot receive the light signal emitted by the light signal transmitter, the packaging pad 10 has reached the specified height. At this time, the lifting assembly can stop operating.

[0042] Optionally, the hopper 1.1 is also equipped with a limit switch 1.1.9, which is mounted on the first linear guide rail 1.1.6 to limit the lifting stroke of the rack 1.1.4.

[0043] Optionally, the conveying mechanism 1.2 includes a first profile 1.2.1, a first movable platform 1.2.2, a first mounting plate 1.2.3, an adsorption assembly, a first lifting drive assembly, and a first lateral movement drive assembly. The first profile 1.2.1 is mounted on the frame and located above the hopper 1.1. The first movable platform 1.2.2 is movably mounted on the first profile 1.2.1. The first mounting plate 1.2.3 is vertically and vertically mounted at the bottom of the first movable platform 1.2.2. The adsorption assembly is located on the bottom surface of the first mounting plate 1.2.3 and is used to selectively adsorb the buffer plate 11 and the high-elasticity film 12. The first lateral movement drive assembly is mounted on the first profile 1.2.1 and connected to the first lifting drive assembly, and is used to drive the first lifting drive assembly to move between the hopper 1.1 and the first folding forming module 2. The first lifting drive assembly is mounted on the frame and connected to the first mounting plate 1.2.3, and is used to drive the first mounting plate 1.2.3 to rise and fall. During material retrieval, the first lateral movement drive component can be used to control the first movable platform 1.2.2 to move the first mounting plate 1.2.3 above the hopper 1.1. Then, the first lifting drive component can be used to control the first mounting plate 1.2.3 to descend. Finally, the adsorption component can be used to adsorb the packaging pad 10 on the material rack 1.1.4 to retrieve the packaging pad 10. Similarly, during material loading, the first lateral movement drive component can be used to control the first movable platform 1.2.2 to move the first mounting plate 1.2.3 above the first folding and forming module 2. Then, the first lifting drive component can be used to control the first mounting plate 1.2.3 to descend. Finally, the adsorption component can be deactivated, and the packaging pad 10 can be placed into the first folding and forming module 2.

[0044] In addition, after the packaging liner 10 is placed into the first folding and forming module 2, the adsorption component can also adsorb the high elastic film 12 on the packaging liner 10, and lift the high elastic film 12 when the first mounting plate 1.2.3 rises, so that a receiving space is formed between the high elastic film 12 of the packaging liner 10 and the buffer plate 11, which is used to place the packaged item.

[0045] Optionally, the adsorption assembly includes multiple nozzles, with a portion of the nozzles used to adsorb the buffer plate 11 and the remainder used to adsorb the high-elasticity membrane 12. For ease of description, the nozzle used to adsorb the buffer plate 11 is defined as the first nozzle 1.2.4, and the nozzle used to adsorb the high-elasticity membrane 12 is defined as the second nozzle 1.2.5. The first nozzle 1.2.4 is respectively disposed at both ends of the bottom surface of the first mounting plate 1.2.3, and the second nozzle 1.2.5 is disposed at the center of the bottom surface of the first mounting plate 1.2.3 and is positioned opposite to the high-elasticity membrane 12.

[0046] Optionally, the first mounting plate 1.2.3 is provided with an arc-shaped groove 1.2.3.1, and the first suction nozzle 1.2.4 is mounted in the arc-shaped groove 1.2.3.1 through a suction nozzle mounting bracket 1.2.3.2 with a slot. In actual use, the position of the first suction nozzle 1.2.4 can be adjusted by adjusting the position of the first suction nozzle 1.2.4 in the suction nozzle mounting bracket 1.2.3.2 (slot), or by adjusting the position of the suction nozzle mounting bracket 1.2.3.2 in the arc-shaped groove 1.2.3.1, so that the adsorption assembly can be used to adsorb packaging liners 10 of different specifications.

[0047] Optionally, the first mounting plate 1.2.3 is provided with a slot, and the second suction nozzle 1.2.5 is installed in the slot. For ease of description, the slot in which the second suction nozzle 1.2.5 is installed is defined as the third slot 1.2.3.3. In actual use, the position of the second suction nozzle 1.2.5 can be adjusted by adjusting its position in the third slot 1.2.3.3, so that the adsorption assembly can be used to adsorb packaging liners 10 of different sizes.

[0048] Optionally, the first lateral movement drive assembly includes a second linear guide rail 1.2.6, a second lead screw 1.2.7, a first slider 1.2.8, and a second servo motor 1.2.9. The second linear guide rail 1.2.6 is mounted on the first profile 1.2.1, and the first movable platform 1.2.2 is slidably mounted on the second linear guide rail 1.2.6 via linear bearings. The second lead screw 1.2.7 is parallel to the second linear guide rail 1.2.6 and rotatably mounted on the first profile 1.2.1 via two first mounting seats 1.2.12. The first slider 1.2.8 is sleeved on the second lead screw 1.2.7 and connected to the first movable platform 1.2.2. The second servo motor 1.2.9 is mounted on the first mounting seat 1.2.12 and connected to the second lead screw 1.2.7. In practical use, when the second servo motor 1.2.9 is started, it can drive the second lead screw 1.2.7 to rotate, so that the first slider 1.2.8 can drive the first movable platform 1.2.2 to move along the second linear guide rail 1.2.6, thereby moving the packaging pad 10 adsorbed by the adsorption component to above the hopper 1.1 or above the first folding module.

[0049] Optionally, the first lifting drive assembly includes a first cylinder 1.2.10 and a first guide post 1.2.11. The first cylinder 1.2.10 is disposed on the first movable platform 1.2.2, and the first cylinder 1.2.10 is provided with a first piston rod 1.2.10.1 for connecting to the first mounting plate 1.2.3. The first guide post 1.2.11 passes through the first movable platform 1.2.2 and its lower end is connected and fixed to the first mounting plate 1.2.3. In specific use, the first cylinder 1.2.10 can extend or retract the first piston rod 1.2.10.1 when it is started. When the first piston rod 1.2.10.1 is extended, the first mounting plate 1.2.3 descends; when the first piston rod 1.2.10.1 is retracted, the first mounting plate 1.2.3 rises. In addition, when the first mounting plate 1.2.3 is raised or lowered, the first guide post 1.2.11 can slide relative to the first movable platform 1.2.2 to guide the first mounting plate 1.2.3.

[0050] Optionally, the first folding and forming module 2 includes a support plate 2.1, a material guide plate 2.2, and a first folding and forming mechanism 2.3. The support plate 2.1 supports the packaging liner 10 (the buffer plate 11). The material guide plate 2.2 is located at the feeding end of the support plate 2.1 and is used to feed the packaged item into the receiving space between the buffer plate 11 and the high-elasticity film 12. The first folding and forming mechanism 2.3 folds the longitudinal ends of the buffer plate 11 so that the longitudinal ends of the buffer plate 11 are folded along the transverse creases 111 to the back of the buffer plate 11, thereby stretching the high-elasticity film 12 to wrap the packaged item. It should be understood that, in a specific configuration, the support plate 2.1 has a width along its transverse direction, which is less than the distance between the two transverse creases 111 of the buffer plate 11, thus enabling the longitudinal ends of the buffer plate 11 to be folded along the transverse creases 111 to the back of the buffer plate 11.

[0051] Optionally, the material guide plate 2.2 is gradually inclined upward in a direction away from the support plate 2.1. This arrangement allows the packaged items placed on the material guide plate 2.2 to slide into the receiving space under the influence of gravity, which can save material loading into the equipment and help reduce energy consumption and costs.

[0052] Optionally, there are two first folding and forming mechanisms 2.3, which are located on the lateral sides of the support plate 2.1 and are used to fold the buffer plate 11 at both ends.

[0053] Optionally, the first folding and forming mechanism 2.3 includes a second mounting plate 2.3.1, a rotating shaft 2.3.2, a first motor 2.3.4, a swing arm, and a second lateral movement drive assembly. The second mounting plate 2.3.1 is movably mounted on the frame. The rotating shaft 2.3.2 is mounted on the second mounting plate 2.3.1 via a bearing seat 2.3.3. The swing arm is radially mounted on the rotating shaft 2.3.2. The first motor 2.3.4 is mounted on the second mounting plate 2.3.1 and connected to the rotating shaft 2.3.2, driving the rotating shaft 2.3.2 to rotate. The swing arm swings as the rotating shaft 2.3.2 rotates, pressing down on the longitudinal ends of the buffer plate 11 to fold it downwards. The second lateral movement drive assembly is mounted on the frame and connected to the second mounting plate 2.3.1, driving the second mounting plate 2.3.1 to move laterally along the support plate 2.1, so that the swing arm pushes down on the longitudinal ends of the buffer plate 11 to fold it onto the back of the buffer plate 11. In practical use, the first motor 2.3.4 drives the rotating shaft 2.3.2 to rotate upon startup, causing the swing arm to swing. During this swing, the swing arm exerts downward pressure on the longitudinal ends of the buffer plate 11, causing the longitudinal ends of the buffer plate 11 to fold downwards. When the longitudinal ends of the buffer plate 11 are vertically downwards, the swing arm maintains a constant swing angle. Simultaneously, the second lateral drive assembly drives the second mounting plate 2.3.1 to move laterally along the support plate 2.1, so that the swing arm applies a lateral thrust to the longitudinal ends of the buffer plate 11, thereby folding the longitudinal ends of the buffer plate 11 onto the back of the buffer plate 11.

[0054] Optionally, the rotating shaft 2.3.2 and the first motor 2.3.4 can be connected by a gear set. For example, a first gear 2.3.5 is sleeved on the end of the rotating shaft 2.3.2, and a second gear 2.3.6 is sleeved on the drive shaft of the first motor 2.3.4. The first gear 2.3.5 and the second gear 2.3.6 mesh. During use, when the first motor 2.3.4 starts, it can drive the second gear 2.3.6 to rotate, and the second gear 2.3.6 in turn drives the first gear 2.3.5 to rotate, thereby causing the rotating shaft 2.3.2 to rotate.

[0055] Optionally, the swing arm includes two rocker arms 2.3.7 and a roller 2.3.8. The two rocker arms 2.3.7 are parallel to each other and are respectively connected to both ends of the rotating shaft 2.3.2. The roller 2.3.8 is connected between the two rocker arms 2.3.7 and is parallel to the rotating shaft 2.3.2. In actual use, the rocker arms 2.3.7 can swing when the rotating shaft 2.3.2 rotates, so that the roller 2.3.8 can apply downward pressure to both ends of the longitudinal direction of the buffer plate 11. Furthermore, when the second mounting plate 2.3.1 moves laterally along the support plate 2.1, the roller 2.3.8 also applies a lateral thrust to both ends of the longitudinal direction of the buffer plate 11. It should be understood that in specific implementations, the length of the roller 2.3.8 can be greater than the lateral dimension of the buffer plate 11, so that the force exerted by the roller 2.3.8 on the buffer plate 11 can be more dispersed, preventing the buffer plate 11 from deforming under stress.

[0056] Optionally, the swing arm also includes rollers 2.3.9, which are fitted onto rollers 2.3.8 and can rotate circumferentially relative to rollers 2.3.8. This arrangement reduces the contact area between rollers 2.3.8 and the buffer plate 11, thereby reducing the friction between them. Simultaneously, the position of rollers 2.3.9 on rollers 2.3.8 can be adjusted to suit different buffer plates 11. Furthermore, since rollers 2.3.9 can rotate circumferentially relative to rollers 2.3.8, the sliding friction between rollers 2.3.8 and the buffer plate 11 is converted into rotational friction between rollers 2.3.9 and the buffer plate 11. This further reduces friction while preventing slippage and damage to the high-elasticity membrane 12 on the buffer plate 11. In addition, the rollers 2.3.9 can maintain line contact with the buffer plate 11, which ensures that during the folding process, the folding force applied by the rollers 2.3.9 to the buffer plate 11 is always perpendicular to the swing direction of the longitudinal ends of the buffer plate 11, making the folding more reliable and preventing the buffer plate 11 from deforming during folding and affecting the folding effect.

[0057] Optionally, the swing arm can also be used to provide support for the packaging pad 10, thereby increasing the accommodating space between the cushioning plate 11 and the high-elasticity film 12. Specifically, during the process of placing the packaging pad 10 on the support plate 2.1, the transport mechanism 1.2 can first place the packaging pad 10 on the rollers 2.3.8 of the swing arm, so that the rollers 2.3.8 support the longitudinal ends of the cushioning plate 11. When the middle part of the cushioning plate 11 (the part between the two transverse creases 111) continues to fall under the action of gravity or the pressure of the transport mechanism 1.2, the longitudinal ends of the cushioning plate 11 can be folded upward. At this time, the transport mechanism 1.2 lifts the high-elasticity film 12 upward, which can increase the accommodating space between the cushioning plate 11 and the high-elasticity film 12, thereby facilitating the loading of the packaged item.

[0058] Optionally, the swing arm also includes two connecting blocks 2.3.10 and a second motor 2.3.11. The two connecting blocks 2.3.10 are rotatably mounted on the two rocker arms 2.3.7 respectively. The second motor 2.3.11 is mounted on one of the rocker arms 2.3.7 and connected to the connecting block 2.3.10 thereon, for driving the connecting block 2.3.10 to rotate relative to the rocker arm 2.3.7. A roller 2.3.8 connects between the two connecting blocks 2.3.10 (i.e., the roller 2.3.8 indirectly connects between the two rocker arms 2.3.7), and the axis of the roller 2.3.8 is parallel to and does not coincide with the rotation center axis of the connecting block 2.3.10. This arrangement allows the roller 2.3.8 to quickly flip from the bottom surface of the buffer plate 11 to the top surface of the buffer plate 11, and improves the folding efficiency of the first folding forming mechanism 2.3. Specifically, because the axis of roller 2.3.8 and the rotation center axis of connecting block 2.3.10 are parallel and do not coincide, roller 2.3.8 can flip when connecting block 2.3.10 rotates. Therefore, when roller 2.3.8 supports the axial ends of buffer plate 11, starting the second motor 2.3.11 alone can change the distance between roller 2.3.8 and support plate 2.1, thereby enabling roller 2.3.8 to quickly flip from the bottom surface of buffer plate 11 to the top surface of buffer plate 11 for subsequent folding operations. In addition, the flipping of roller 2.3.8 can also achieve the folding of the longitudinal ends of buffer plate 11. Therefore, in the subsequent folding operation, if the first motor 2.3.4 and the second motor 2.3.11 are started simultaneously, the folding efficiency of the first folding forming mechanism 2.3 can be improved.

[0059] Optionally, there are two rollers 2.3.8, located at opposite ends of the rotation center axis of the connecting block 2.3.10. This arrangement improves the working efficiency of the first folding and forming mechanism 2.3. Specifically, during use, the two rollers 2.3.8 are initially positioned one inside and one outside. The swing arm can initially use the inner roller 2.3.8 to support the buffer plate 11. After the packaged item is placed into the receiving space, the connecting block 2.3.10 only needs to rotate a small angle to flip the outer roller 2.3.8 to the top surface of the buffer plate 11. Compared to using a single roller 2.3.8, this reduces the rotation angle of the connecting block 2.3.10, thereby improving the working efficiency of the first folding and forming mechanism 2.3.

[0060] Optionally, the second traverse drive assembly includes a third linear guide 2.3.12 and a drive unit. The third linear guide 2.3.12 is mounted on the frame, and the second mounting plate 2.3.1 is mounted on and slidably engages with the third linear guide 2.3.12. The drive unit can be a cylinder or other linear drive mechanism. The drive unit is mounted on the frame and connected to the second mounting plate 2.3.1, and is used to drive the second mounting plate 2.3.1 to move along the third linear guide 2.3.12.

[0061] Optionally, the second folding and forming module 3 includes a slide rail 3.1, a pulling mechanism 3.2, and a second folding and forming mechanism 3.3. The pulling mechanism 3.2 is used to drag the once-folded packaging pad 10 from the support plate 2.1 to the slide rail 3.1. The slide rail 3.1 is used to support the lateral ends of the cushioning plate 11. The second folding and forming mechanism 3.3 is used to apply pressure to the cushioning plate 11, so that the cushioning plate 11 moves downward and folds its lateral ends along the longitudinal crease 112 to both sides of the packaged item.

[0062] Optionally, the slide rail 3.1 includes a first slide rail 3.1.1, a second slide rail 3.1.2, a third slide rail 3.1.3, and a second lifting drive assembly. The first slide rail 3.1.1 and the third slide rail 3.1.3 are mounted on the frame. The second slide rail 3.1.2 is vertically mounted between the first slide rail 3.1.1 and the third slide rail 3.1.3. The second lifting drive assembly is mounted on the frame and connected to the second slide rail 3.1.2, and is used to drive the second slide rail 3.1.2 to move up and down. In a specific configuration, the first slide rail 3.1.1, the second slide rail 3.1.2, and the third slide rail 3.1.3 are arranged sequentially, and the outer end of the first slide rail 3.1.1 is connected to the unloading end of the support plate 2.1 (the end away from the material guide plate 2.2). In practical use, the second lifting drive assembly can be used to drive the second slide rail 3.1.2 to rise so that its upper surface is flush with the first slide rail 3.1.1 and the third slide rail 3.1.3. After the pulling mechanism 3.2 pulls the packaging pad 10 onto the slide rail 3.1, the second lifting drive assembly can be used to drive the second slide rail 3.1.2 to fall so that its upper surface is lower than the first slide rail 3.1.1 and the third slide rail 3.1.3. At this time, the first slide rail 3.1.1 and the third slide rail 3.1.3 support the two lateral ends of the buffer plate 11 respectively, so that the second folding forming mechanism 3.3 can perform subsequent folding operations.

[0063] Optionally, when the second folding and forming mechanism 3.3 applies pressure to the buffer plate 11 to lower it, the second lifting drive assembly drives the second slide rail 3.1.2 to descend. That is, when the buffer plate 11 is folded for the second time, the second lifting drive assembly and the second folding and forming mechanism 3.3 descend synchronously. This arrangement ensures that the bottom of the buffer plate 11 is always stably supported when folded, preventing it from being suspended in the air, thereby avoiding damage to the buffer plate 11 or affecting the folding effect when the second folding and forming mechanism 3.3 applies pressure to the buffer plate 11.

[0064] Optionally, both the first slide rail 3.1.1 and the third slide rail 3.1.3 have guide plates at one end near the second slide rail 3.1.2. These guide plates guide the buffer plate 11 as it descends. For ease of description, the guide plate of the first slide rail 3.1.1 is defined as the first guide plate 3.1.4, and the guide plate of the third slide rail 3.1.3 is defined as the second guide plate 3.1.5. In practical use, the middle part of the buffer plate 11 can descend under the pressure of the second folding mechanism 3.3. During this descent, the first guide plate 3.1.4 and the second guide plate 3.1.5 act as guides. It should be understood that, in specific configurations, the distance between the first guide plate 3.1.4 and the second guide plate 3.1.5 can be equal to the distance between the two transverse folds 111 of the buffer plate 11. This avoids affecting the folding effect due to an excessively large distance between the first guide plate 3.1.4 and the second guide plate 3.1.5.

[0065] Optionally, the second lifting drive assembly includes a second movable platform 3.1.6, support columns 3.1.7, and a second cylinder 3.1.8. The second movable platform 3.1.6 is movably disposed below the second slide rail 3.1.2 and connected to the bottom surface of the second slide rail 3.1.2 via multiple support columns 3.1.7. The second cylinder 3.1.8 is disposed on the frame and located below the second movable platform 3.1.6, and is provided with a second piston rod 3.1.8.1 for connecting the second movable platform 3.1.6. In practical use, the second cylinder 3.1.8 can extend or retract the second piston rod 3.1.8.1 when activated. When the second piston rod 3.1.8.1 is extended, the second movable platform 3.1.6 can drive the second slide rail 3.1.2 to rise; when the second piston rod 3.1.8.1 is retracted, the second movable platform 3.1.6 can drive the second slide rail 3.1.2 to descend.

[0066] Optionally, the pulling mechanism 3.2 includes a gripper mounting base 3.2.1, a first gripper 3.2.2, and a third lateral movement drive assembly. The gripper mounting base 3.2.1 is movably mounted on the frame. The first gripper 3.2.2 is mounted on the gripper mounting base 3.2.1 and is used to clamp the once-folded packaging pad 10 when the gripper mounting base 3.2.1 is close to the support plate 2.1. The third lateral movement drive assembly is mounted on the frame and connected to the gripper mounting base 3.2.1, and is used to drive the gripper mounting base 3.2.1 to move, thereby dragging the packaging pad 10 to the slide rail 3.1. During the dragging of the packaging pad 10, the third lateral drive assembly can first be used to move the gripper mounting base 3.2.1 to the unloading end of the support plate 2.1. Once the first gripper 3.2.2 clamps one lateral end of the buffer plate 11, the third lateral drive assembly can be used to reset the gripper mounting base 3.2.1, thereby dragging the packaging pad 10 onto the slide rail 3.1. It should be understood that, in specific configurations, the first gripper 3.2.2 can move between the two tracks of the slide rail 3.1, eliminating the need to raise or lower the first gripper 3.2.2, thus improving operational efficiency.

[0067] Optionally, the third traverse drive assembly includes a third lead screw 3.2.3, a slide bar 3.2.4, and a third motor 3.2.5. The third lead screw 3.2.3 is rotatably mounted on the frame via two second mounting seats 3.2.6. The slide bar 3.2.4 is parallel to the third lead screw 3.2.3 and connected between the two second mounting seats 3.2.6. Gripper mounting seats 3.2.1 are respectively fitted onto the slide bar 3.2.4 and the third lead screw 3.2.3. The third motor 3.2.5 is mounted on one of the second mounting seats 3.2.6 and connected to the third lead screw 3.2.3. In practical use, when the third motor 3.2.5 starts, it can drive the third lead screw 3.2.3 to rotate, causing the gripper mounting seat 3.2.1 to move axially along the slide bar 3.2.4. It should be understood that, in a specific configuration, the third traverse drive assembly can be located below the slide rail 3.1, which allows for a tighter assembly of the equipment and helps to reduce the structural dimensions of the equipment.

[0068] Optionally, the second folding and forming mechanism 3.3 includes a second profile 3.3.1, a third movable platform 3.3.2, a third mounting plate 3.3.3, a pressure plate 3.3.4, and a third lifting drive assembly. The second profile 3.3.1 is mounted on the frame and located above the slide rail 3.1. The third movable platform 3.3.2 is mounted on the second profile 3.3.1. The third mounting plate 3.3.3 is vertically and flexibly mounted at the bottom of the third movable platform 3.3.2. The pressure plate 3.3.4 is located at both ends of the bottom surface of the third mounting plate 3.3.3. The third lifting drive assembly is mounted on the third movable platform 3.3.2 and connected to the third mounting plate 3.3.3, and is used to drive the third mounting plate 3.3.3 to lift. In practical use, the third lifting drive assembly can be used to control the third mounting plate 3.3.3 to descend, so that the pressure plate 3.3.4 presses down on both ends of the middle portion of the buffer plate 11, causing it to descend, and folds the lateral ends of the buffer plate 11 to both sides of the packaged item.

[0069] Optionally, the third lifting drive assembly includes a third cylinder 3.3.5 and a second guide post 3.3.6. The third cylinder 3.3.5 is mounted on the third movable platform 3.3.2 and is provided with a third piston rod 3.3.5.1 for connecting to the third mounting plate 3.3.3. The second guide post 3.3.6 passes through the third movable platform 3.3.2 and its lower end is connected and fixed to the third mounting plate 3.3.3. In actual use, when the third cylinder 3.3.5 is activated, it can extend or retract the third piston rod 3.3.5.1. When the third piston rod 3.3.5.1 is extended, the third mounting plate 3.3.3 descends; when the third piston rod 3.3.5.1 is retracted, the third mounting plate 3.3.3 rises. In addition, when the third mounting plate 3.3.3 is raised or lowered, the second guide post 3.3.6 can slide relative to the third movable platform 3.3.2 to guide the third mounting plate 3.3.3.

[0070] Optionally, the second folding and forming mechanism 3.3 further includes a flexible pressure block 3.3.7, which is disposed on the bottom surface of the third mounting plate 3.3.3. In specific configurations, the flexible pressure block 3.3.7 can be a stretchable sponge, spring, or similar material. When the third mounting plate 3.3.3 descends, the flexible pressure block 3.3.7 can appropriately contract and provide support between the third mounting plate 3.3.3 and the packaged item. This configuration disperses the pressure of the third mounting plate 3.3.3, preventing damage to the buffer plate 11 due to excessive pressure. Furthermore, the flexible pressure block 3.3.7 ensures more even force distribution on the buffer plate 11, preventing stress concentration at the crease when the pressure plate 3.3.4 presses down, reducing the risk of damage at the crease. In addition, the stretchability of the flexible pressure block 3.3.7 reduces the pressure on the packaged item, preventing damage due to excessive pressure.

[0071] Optionally, the second folding and forming mechanism 3.3 is also used to deliver the folded packaging pad 10 from the second folding and forming module 3 to the next station.

[0072] Optionally, the second folding and forming mechanism 3.3 further includes a second gripper 3.3.8 and a fourth transverse drive assembly. The second gripper 3.3.8 is disposed at both ends of the bottom surface of the third mounting plate 3.3.3. The fourth transverse drive assembly is disposed on the second folding and forming module 3 and connected to the third movable platform 3.3.2, for driving the third movable platform 3.3.2 to move between the second folding and forming module 3 and the next station. In specific use, after the folding operation of the buffer plate 11 is completed, the second gripper 3.3.8 can clamp the transverse ends of the buffer plate 11. Then, when the third mounting plate 3.3.3 rises, the folded packaging pad 10 can be removed from the slide rail 3.1. Finally, the fourth transverse drive assembly drives the third movable platform 3.3.2 to move transversely, which can send the folded packaging pad 10 to the next station.

[0073] Optionally, the second gripper 3.3.8 can be vertically mounted on the third mounting plate 3.3.3. For example, the third mounting plate 3.3.3 is provided with a gripper cylinder 3.3.9, and the second gripper 3.3.8 is connected to the piston rod of the gripper cylinder 3.3.9, so that the second gripper 3.3.8 can rise and fall when the piston rod of the gripper cylinder 3.3.9 extends or retracts. This arrangement can prevent the second gripper 3.3.8 from directly interfering with the slide rail 3.1, thereby affecting the folding operation of the second folding and forming mechanism 3.3.

[0074] Optionally, the fourth lateral movement drive assembly includes a fourth linear guide rail 3.3.10, a fourth lead screw 3.3.11, a second slider 3.3.12, and a fourth motor 3.3.13. The fourth linear guide rail 3.3.10 is mounted on the second profile 3.3.1, and the third movable platform 3.3.2 is mounted on and slidably engages with the fourth linear guide rail 3.3.10. The fourth lead screw 3.3.11 is parallel to the fourth linear guide rail 3.3.10 and rotatably mounted on the second profile 3.3.1 via two third mounting seats 3.3.14. The second slider 3.3.12 is sleeved on the fourth lead screw 3.3.11 and connected to the third movable platform 3.3.2. The fourth motor 3.3.13 is mounted on one of the third mounting seats 3.3.14 and connected to the fourth lead screw 3.3.11. In practical use, when the fourth motor 3.3.13 starts, it can drive the fourth lead screw 3.3.11 to rotate, so that the second slider 3.3.12 can drive the third movable platform 3.3.2 to move along the axial direction of the fourth linear guide rail 3.3.10, thereby moving the packaging pad 10 held by the second gripper 3.3.8 to the next station.

[0075] The automatic forming equipment for packaging liners 10 in this application realizes a series of complex actions such as automated feeding, folding and forming, and packaging of suspended packaging, avoiding the quality risks caused by inaccurate positioning and low stability of current manual operation, while solving problems such as low efficiency.

[0076] The following is combined Figures 9 to 22 The working process of the automatic forming equipment for packaging liners 10 according to embodiments of this application is described.

[0077] like Figure 9 and Figure 10 As shown, the first lifting drive assembly controls the first movable platform 1.2.2 to descend. After the first suction nozzle 1.2.4 picks up the packaging pad 10 from the material bin 1.1, the first lateral drive assembly controls the first movable platform 1.2.2 to move laterally above the first folding and forming module 2. Simultaneously, the positioning detector 1.1.8 detects that the packaging pad 10 has not reached the specified height, and then controls the first servo motor 1.1.7 to work, causing the material rack 1.1.4 to rise until the packaging pad 10 reaches the specified height.

[0078] Adjust the rocker arm 2.3.7 of the first folding and forming mechanism 2.3 to... Figure 10 As shown, the height of both rollers 2.3.8 is higher than that of the support plate 2.1, and the rocker arm 2.3.7, which is away from the support plate 2.1, is located outside the packaging pad 10, while the rocker arm 2.3.7, which is close to the support plate 2.1, is located below the longitudinal ends of the packaging pad 10 and supports the longitudinal ends of the buffer plate 11.

[0079] like Figure 11 As shown, the first mounting plate 1.2.3 is lowered by the first lifting drive assembly until the bottom surface of the middle part of the buffer plate 11 contacts the upper surface of the support plate 2.1. During the descent, the longitudinal ends of the buffer plate 11 are folded upward at a certain angle due to the obstruction of the rollers 2.3.8.

[0080] like Figure 12 As shown, the first suction nozzle 1.2.4 de-vacuums, while the second suction nozzle 1.2.5 emboldens, adsorbing the high-elasticity film 12 of the packaging liner 10. As the first lifting drive assembly controls the first mounting plate 1.2.3 to rise, the high-elasticity film 12 is lifted and held stationary. Subsequently, the packaged item 20 can be pushed into the receiving space between the buffer plate 11 and the high-elasticity film 12 via the material guide plate 2.2. Once the packaged item 20 is in place, the second suction nozzle 1.2.5 de-vacuums, allowing the conveying mechanism 1.2 to perform the next material retrieval.

[0081] like Figures 13 to 17As shown, with the position and orientation of the rocker arm 2.3.7 unchanged, the second motor 2.3.11 is activated. The second motor 2.3.11 controls the rollers 2.3.8 to rotate, so that the rollers 2.3.8 away from the support plate 2.1 rotate to contact the upper surfaces of the longitudinal ends of the buffer plate 11. Subsequently, the first motor 2.3.4 and the second motor 2.3.11 are activated simultaneously, controlling the rocker arm 2.3.7 to swing downward to a horizontal state. At this time, both rollers 2.3.8 are in contact with the longitudinal ends of the buffer plate 11, and both rollers 2.3.8 are located below the support plate 2.1. Keeping the position and orientation of the rocker arm 2.3.7 unchanged, the second mounting plate 2.3.1 is controlled to move laterally along the support plate 2.1 through the second lateral drive assembly, so that the rollers 2.3.8 apply a lateral thrust to the longitudinal ends of the buffer plate 11 until the longitudinal ends of the buffer plate 11 are folded to the back of the buffer plate 11.

[0082] like Figure 18 and Figure 19 As shown, the third motor 3.2.5 is started. The third motor 3.2.5 controls the first gripper 3.2.2 to move to the unloading end of the support plate 2.1. When the first gripper 3.2.2 clamps the transverse end of the buffer plate 11, the third motor 3.2.5 drives the first gripper 3.2.2 in the reverse direction. During the resetting process of the first gripper 3.2.2, the packaging pad 10 can be dragged onto the slide rail 3.1 so that the first slide rail 3.1.1, the second slide rail 3.1.2 and the third slide rail 3.1.3 simultaneously support the buffer plate 11.

[0083] like Figure 19 and Figure 20 As shown, the fourth motor 3.3.13 is activated, which controls the third movable platform 3.3.2 to move above the packaging pad 10. The third cylinder 3.3.5 is activated, which controls the third mounting plate 3.3.3 to descend. When the pressure plate 3.3.4 contacts the buffer plate 11 and the flexible pressure block 3.3.7 contacts the packaged item 20, the second cylinder 3.1.8 is activated simultaneously, causing the buffer plate 11 and the second slide rail 3.1.2 to descend synchronously. During the descent, the two lateral ends of the buffer plate 11 are folded upwards due to the obstruction of the first slide rail 3.1.1 and the third slide rail 3.1.3, until the two lateral ends of the buffer plate 11 are folded to the sides of the packaged item 20.

[0084] like Figure 21 and Figure 22As shown, keeping the position of the third mounting plate 3.3.3 unchanged, the gripper cylinder 3.3.9 is activated. The gripper cylinder 3.3.9 controls the second gripper 3.3.8 to move downwards. After the second gripper 3.3.8 clamps the two lateral ends of the buffer plate 11, the gripper cylinder 3.3.9 controls the second gripper 3.3.8 to move upwards. At the same time, the third cylinder 3.3.5 controls the third mounting plate 3.3.3 to move upwards until the packaging pad 10 is disengaged from the slide rail 3.1. Then, the fourth motor 3.3.13 is activated. The fourth motor 3.3.13 controls the third movable platform 3.3.2 to move, which can move the folded packaging pad 10 together with the packaged item 20 to the next workstation. After the folded packaging pad 10 is delivered to the designated position, the second folding and forming mechanism 3.3 can be reset.

[0085] One or more embodiments in this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this specification should be included within the protection scope of this application.

[0086] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
