The second transverse driving assembly is arranged 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 laterally along the support plate 2.1, so that the swing arm pushes the longitudinal ends of the buffer plate 11 horizontally to fold it on the back of the buffer plate 11. In specific use, the first motor 2.3.4 can drive the rotating shaft 2.3.2 to rotate when it is started, and at the same time, the swing arm can swing. When the swing arm swings, it can generate downward pressure on the longitudinal ends of the buffer plate 11, so that the longitudinal ends of the buffer plate 11 are folded downward. When the longitudinal ends of the buffer plate 11 are vertically downward, the swing arm maintains the swing angle unchanged, and at the same time, the second transverse driving assembly drives the second mounting plate 2.3.1 to move transversely along the support plate 2.1, so that the swing arm applies a transverse thrust to the longitudinal ends of the buffer plate 11, so that the longitudinal ends of the buffer plate 11 are folded on 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 via a gear set. For example, the end of the rotating shaft 2.3.2 is sleeved with a first gear 2.3.5, and the driving shaft of the first motor 2.3.4 is sleeved with a second gear 2.3.6, and the first gear 2.3.5 and the second gear 2.3.6 are meshed. During use, when the first motor 2.3.4 is started, 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 rotating the rotating shaft 2.3.2.

[0055] Optionally, the swing arm includes two rockers 2.3.7 and a roller 2.3.8. The two rockers 2.3.7 are parallel to each other and are respectively connected to the two ends of the rotating shaft 2.3.2. The roller 2.3.8 is connected between the two rockers 2.3.7 and is parallel to the rotating shaft 2.3.2. In specific use, the rocker 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 the longitudinal ends of the buffer plate 11, and 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 the longitudinal ends of the buffer plate 11. It should be understood that in a specific implementation, the length of the roller 2.3.8 can be greater than the lateral size of the buffer plate 11, so that the force of the roller 2.3.8 acting on the buffer plate 11 can be more dispersed, preventing the buffer plate 11 from being deformed by force.

[0056] Optionally, the swing arm further comprises a roller 2.3.9, which is sleeved on the roller 2.3.8 and can rotate relative to the circumference of the roller 2.3.8. This arrangement can reduce the contact area between the roller 2.3.8 and the buffer plate 11, that is, reduce the friction between the roller 2.3.8 and the buffer plate 11, and at the same time, the position of the roller 2.3.9 on the roller 2.3.8 can be adjusted to be suitable for different buffer plates 11. In addition, since the roller 2.3.9 can rotate relative to the circumference of the roller 2.3.8, the sliding friction between the roller 2.3.8 and the buffer plate 11 can be converted into the rotational friction between the roller 2.3.9 and the buffer plate 11, while further reducing the friction, avoiding sliding damage to the high elastic film 12 on the buffer plate 11. In addition, the roller 2.3.9 can maintain line contact with the buffer plate 11, that is, to ensure that during the folding process, the folding force applied by the roller 2.3.9 on the buffer plate 11 is always perpendicular to the swinging direction of the longitudinal ends of the buffer plate 11, making the folding more reliable and avoiding deformation of the buffer plate 11 during folding, which affects the folding effect.

[0057] Optionally, the swing arm can also be used to provide support force for the packaging cushion 10 to increase the accommodation space between the buffer plate 11 and the high elastic film 12. Specifically, when the transport mechanism 1.2 places the packaging cushion 10 on the support plate 2.1, the transport mechanism 1.2 can first place the packaging cushion 10 on the roller 2.3.8 of the swing arm, so that the roller 2.3.8 supports the longitudinal ends of the buffer plate 11. When the middle part of the buffer plate 11 (the part between the two transverse folds 111) continues to fall under the action of gravity or the pressure of the transport mechanism 1.2, the longitudinal ends of the buffer plate 11 can be folded upwards. At this time, the transport mechanism 1.2 pulls up the high elastic film 12, which can increase the accommodation space between the buffer plate 11 and the high elastic film 12, so that it is convenient to load the packaged objects.

[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 arranged on the two rocking arms 2.3.7 respectively. The second motor 2.3.11 is arranged on one of the rocking arms 2.3.7 and connected to the connecting block 2.3.10 thereon, and is used to drive the connecting block 2.3.10 to rotate relative to the rocking arm 2.3.7. The roller 2.3.8 is connected between the two connecting blocks 2.3.10 (that is, the roller 2.3.8 is indirectly connected between the two rocking arms 2.3.7), and the axis of the roller 2.3.8 and the center axis of rotation of the connecting block 2.3.10 are parallel and do not overlap with each other. This arrangement can enable 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 can improve the folding efficiency of the first folding and forming mechanism 2.3. Specifically, since the axis of the roller 2.3.8 and the rotation center axis of the connecting block 2.3.10 are parallel and do not overlap each other, the roller 2.3.8 can be turned over when the connecting block 2.3.10 rotates. Therefore, when the roller 2.3.8 supports the axial ends of the buffer plate 11, starting the second motor 2.3.11 alone can change the distance between the roller 2.3.8 and the support plate 2.1, so that the roller 2.3.8 can be quickly turned over from the bottom surface of the buffer plate 11 to the top surface of the buffer plate 11 for subsequent folding operations. In addition, when the roller 2.3.8 is turned over, the folding of the longitudinal ends of the buffer plate 11 can also be achieved. Therefore, in the subsequent folding operation, if the first motor 2.3.4 and the second motor 2.3.11 are started at the same time, the folding efficiency of the first folding and forming mechanism 2.3 can be improved.

[0059] Optionally, there are two rollers 2.3.8, and the two rollers 2.3.8 are respectively located at opposite ends of the central axis of rotation of the connecting block 2.3.10. This arrangement can improve the working efficiency of the first folding and forming mechanism 2.3. Specifically, during use, the two rollers 2.3.8 are first arranged in an inner and outer manner, and the swing arm can first use the roller 2.3.8 located on the inner side to support the buffer plate 11. After the packaged objects are placed in the accommodating space, the connecting block 2.3.10 only needs to rotate a small angle to flip the roller 2.3.8 located on the outer side to the top surface of the buffer plate 11. Compared with the method of using a single roller 2.3.8, in this way, the rotation angle of the connecting block 2.3.10 can be reduced, thereby improving the working efficiency of the first folding and forming mechanism 2.3.

[0060] Optionally, the second transverse drive assembly includes a third linear guide rail 2.3.12 and a drive unit. The third linear guide rail 2.3.12 is arranged on the frame, and the second mounting plate 2.3.1 is arranged on the third linear guide rail 2.3.12 and slidably cooperates with the third linear guide rail 2.3.12. The drive unit can be a cylinder or other linear drive mechanism, and the drive unit is arranged 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 rail 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 packaging liner 10 after the first folding 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 buffer plate 11. The second folding and forming mechanism 3.3 is used to press the buffer plate 11 so that the buffer plate 11 moves downward and folds its lateral ends to the two sides of the packaged object according to the longitudinal fold 112.

[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 arranged on the frame. The second slide rail 3.1.2 can be lifted between the first slide rail 3.1.1 and the third slide rail 3.1.3. The second lifting drive assembly is arranged 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 lift. In the specific setting, the first slide rail 3.1.1, the second slide rail 3.1.2 and the third slide rail 3.1.3 are arranged in sequence, 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). During specific use, the second lifting drive assembly can be used to first 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 drags 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 descend 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 respectively support the lateral ends of the buffer plate 11, so that the second folding and 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 make it move downward, the second lifting drive assembly drives the second slide rail 3.1.2 to move downward. 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 move downward synchronously. This arrangement ensures that the bottom of the buffer plate 11 always has a stable support when it is folded, and avoids it from hanging in the air, thereby preventing the buffer plate 11 from being damaged or affecting the folding effect when the second folding and forming mechanism 3.3 applies pressure to the buffer plate 11.

[0064] Optionally, the first slide rail 3.1.1 and the third slide rail 3.1.3 are both provided with a guide plate at one end close to the second slide rail 3.1.2, and the guide plate is used to guide the buffer plate 11 when the buffer plate 11 moves downward. For the convenience 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 specific use, the middle part of the buffer plate 11 can move downward when subjected to the pressure of the second folding and forming mechanism 3.3. During the downward movement, the first guide plate 3.1.4 and the second guide plate 3.1.5 can play a guiding role. It should be understood that in the specific setting, the distance between the first guide plate 3.1.4 and the second guide plate 3.1.5 can be equal to the spacing between the two transverse folds 111 of the buffer plate 11, so that the folding effect can be avoided from being affected by the excessive 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, a support column 3.1.7 and a second cylinder 3.1.8. The second movable platform 3.1.6 is arranged below the second slide rail 3.1.2 in a liftable manner and is connected to the bottom surface of the second slide rail 3.1.2 through a plurality of support columns 3.1.7. The second cylinder 3.1.8 is arranged on the frame and located below the second movable platform 3.1.6. The second cylinder 3.1.8 is provided with a second piston rod 3.1.8.1 for connecting the second movable platform 3.1.6. In specific use, the second cylinder 3.1.8 can extend or retract the second piston rod 3.1.8.1 when starting. 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 traction mechanism 3.2 includes a clamping jaw mounting seat 3.2.1, a first clamping jaw 3.2.2 and a third transverse driving assembly. The clamping jaw mounting seat 3.2.1 is movably arranged on the frame. The first clamping jaw 3.2.2 is arranged on the clamping jaw mounting seat 3.2.1, and is used to clamp the packaging liner 10 that has been folded once when the clamping jaw mounting seat 3.2.1 is close to the support plate 2.1. The third transverse driving assembly is arranged on the frame and connected to the clamping jaw mounting seat 3.2.1, and is used to drive the clamping jaw mounting seat 3.2.1 to move, so as to drag the packaging liner 10 to the slide rail 3.1. In the process of dragging the packaging liner 10, the third transverse driving assembly can be used to first move the clamping jaw mounting seat 3.2.1 to the unloading end of the support plate 2.1, and when the first clamping jaw 3.2.2 clamps the lateral end of the buffer plate 11, the third transverse driving assembly can be used to reset the clamping jaw mounting seat 3.2.1 to drag the packaging liner 10 onto the slide rail 3.1. It should be understood that in a specific setting, the first clamping jaw 3.2.2 can move between the two rails of the slide rail 3.1, so that there is no need to raise or lower the first clamping jaw 3.2.2, which is conducive to improving the operation efficiency.

[0067] Optionally, the third transverse driving assembly includes a third screw rod 3.2.3, a slide bar 3.2.4 and a third motor 3.2.5. The third screw rod 3.2.3 is rotatably mounted on the frame through two second mounting seats 3.2.6. The slide bar 3.2.4 is parallel to the third screw rod 3.2.3 and connected between the two second mounting seats 3.2.6, and the clamping claw mounting seat 3.2.1 is respectively sleeved on the slide bar 3.2.4 and the third screw rod 3.2.3. The third motor 3.2.5 is arranged on one of the second mounting seats 3.2.6 and is connected to the third screw rod 3.2.3. When in specific use, the third motor 3.2.5 can drive the third screw rod 3.2.3 to rotate when it is started, so that the clamping claw mounting seat 3.2.1 moves axially along the slide bar 3.2.4. It should be understood that in the specific setting, the third transverse driving assembly can be located below the slide rail 3.1, so that the equipment can be assembled more tightly, which is conducive to reducing the structural size 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 pressing plate 3.3.4 and a third lifting drive assembly. The second profile 3.3.1 is arranged on the frame and is located above the slide rail 3.1. The third movable platform 3.3.2 is arranged on the second profile 3.3.1. The third mounting plate 3.3.3 is arranged at the bottom of the third movable platform 3.3.2 in a liftable manner. The pressing plate 3.3.4 is arranged at both ends of the bottom surface of the third mounting plate 3.3.3. The third lifting drive assembly is arranged 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 rise and fall. When used specifically, the third lifting drive assembly can be used to control the third mounting plate 3.3.3 to descend, so that the pressing plate 3.3.4 presses down the two ends of the middle part of the buffer plate 11 to make it descend, and folds the lateral ends of the buffer plate 11 on both sides of the packaged object.

[0069] Optionally, the third lifting drive assembly includes a third cylinder 3.3.5 and a second guide column 3.3.6. The third cylinder 3.3.5 is installed on the third movable platform 3.3.2, and the third cylinder 3.3.5 is provided with a third piston rod 3.3.5.1 for connecting the third mounting plate 3.3.3. The second guide column 3.3.6 is penetrated through the third movable platform 3.3.2 and the lower end is connected and fixed to the third mounting plate 3.3.3. In specific use, the third cylinder 3.3.5 can extend or retract the third piston rod 3.3.5.1 when starting. When the third piston rod 3.3.5.1 is extended, the third mounting plate 3.3.3 descends, and 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 lifted or lowered, the second guide column 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 also includes a flexible pressing block 3.3.7, which is arranged on the bottom surface of the third mounting plate 3.3.3. In the specific setting, the flexible pressing block 3.3.7 can be a retractable sponge, spring, etc. When the third mounting plate 3.3.3 descends, the flexible pressing block 3.3.7 can be appropriately contracted and supported between the third mounting plate 3.3.3 and the packaged object. This setting can disperse the pressure of the third mounting plate 3.3.3 to avoid damage to the buffer plate 11 due to excessive pressure. In addition, the flexible pressing block 3.3.7 also makes the buffer plate 11 more evenly stressed, avoiding concentrated stress at the crease when the pressing plate 3.3.4 is pressed down, reducing the risk of damage at the crease. In addition, since the flexible pressing block 3.3.7 is retractable, it can reduce the pressure on the packaged object and prevent the packaged object from being damaged due to excessive pressure.

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

[0072] Optionally, the second folding and forming mechanism 3.3 also includes a second clamp 3.3.8 and a fourth transverse drive assembly. The second clamp 3.3.8 is arranged at both ends of the bottom surface of the third mounting plate 3.3.3. The fourth transverse drive assembly is arranged on the second forming and connected to the third movable platform 3.3.2, and is used to drive 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 lateral ends of the buffer plate 11 can be clamped by the second clamp 3.3.8, and then the folded packaging pad 10 can be taken out from the slide rail 3.1 when the third mounting plate 3.3.3 rises, and finally the third movable platform 3.3.2 is driven to move transversely by the fourth transverse drive assembly, so that the folded packaging pad 10 can be sent to the next station.

[0073] Optionally, the second clamping jaw 3.3.8 is mounted on the third mounting plate 3.3.3 in a manner that it can be raised or lowered. For example, a clamping jaw cylinder 3.3.9 is provided on the third mounting plate 3.3.3, and the second clamping jaw 3.3.8 is connected to the piston rod of the clamping jaw cylinder 3.3.9, so that the second clamping jaw 3.3.8 can be raised or lowered when the clamping jaw cylinder 3.3.9 retracts the piston rod. This arrangement can prevent the second clamping jaw 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 transverse drive assembly includes a fourth linear guide 3.3.10, a fourth screw rod 3.3.11, a second slider 3.3.12 and a fourth motor 3.3.13. The fourth linear guide 3.3.10 is arranged on the second profile 3.3.1, and the third movable platform 3.3.2 is arranged on the fourth linear guide 3.3.10 and slidably cooperates with the fourth linear guide 3.3.10. The fourth screw rod 3.3.11 is parallel to the fourth linear guide 3.3.10 and is rotatably mounted on the second profile 3.3.1 through two third mounting seats 3.3.14. The second slider 3.3.12 is sleeved on the fourth screw rod 3.3.11 and connected to the third movable platform 3.3.2. The fourth motor 3.3.13 is arranged on one of the third mounting seats 3.3.14 and connected to the fourth screw rod 3.3.11. In specific use, the fourth motor 3.3.13 can drive the fourth screw 3.3.11 to rotate when started, so that the second slider 3.3.12 can drive the third movable platform 3.3.2 to move axially along the fourth linear guide 3.3.10, thereby moving the packaging cushion 10 clamped by the second clamp 3.3.8 to the next station.

[0075] The automatic forming equipment of the packaging pad 10 in the embodiment of the present application realizes a series of complex actions such as automatic loading, folding and forming, and packaging of suspended solid packaging, avoiding the quality risks caused by inaccurate positioning and low stability of current manual operations, and solving problems such as low efficiency.

[0076] Combine the following Figures 9 to 22 The working process of the automatic forming device for the packaging liner 10 according to the embodiment of the present application is introduced.

[0077] like Fig. 9 and Fig.10 As shown, the first movable platform 1.2.2 is controlled to descend by the first lifting drive assembly, and after the first suction nozzle 1.2.4 sucks the packaging liner 10 in the material bin 1.1, the first movable platform 1.2.2 is controlled to move horizontally to above the first folding and forming module 2 by the first transverse driving assembly. At the same time, if the in-position detector 1.1.8 detects that the packaging liner 10 has not reached the specified height, the first servo motor 1.1.7 is controlled to work, so that the material rack 1.1.4 rises until the packaging liner 10 reaches the specified height.

[0078] Adjust the rocker 2.3.7 of the first folding and forming mechanism 2.3 to Fig.10 In the position shown, the heights of the two rollers 2.3.8 are both higher than the support plate 2.1, and the rocker 2.3.7 away from the support plate 2.1 is located outside the packaging cushion 10, and the rocker 2.3.7 close to the support plate 2.1 is located below the longitudinal ends of the packaging cushion 10 and supports the longitudinal ends of the buffer plate 11.

[0079] like Fig.11 As shown, the first mounting plate 1.2.3 is controlled to descend 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 process, the longitudinal ends of the buffer plate 11 are blocked by the rollers 2.3.8 and fold upward at a certain angle.

[0080] like Fig.12 As shown, the first suction nozzle 1.2.4 breaks the vacuum, and the second suction nozzle 1.2.5 turns on the vacuum to absorb the high elastic film 12 of the packaging cushion 10. As the first lifting drive assembly controls the first mounting plate 1.2.3 to rise, the high elastic film 12 is pulled up and kept still. Then, the packaged object 20 can be pushed to the accommodation space between the buffer plate 11 and the high elastic film 12 through the material guide plate 2.2. After the packaged object 20 is in place, the second suction nozzle 1.2.5 breaks the vacuum, and the transport mechanism 1.2 can take the material for the next time.

[0081] like Figures 13 to 17As shown, the position and posture of the rocker 2.3.7 remain unchanged, and the second motor 2.3.11 is started. The second motor 2.3.11 controls the roller 2.3.8 to flip, so that the roller 2.3.8 away from the support plate 2.1 flips to contact the upper surface of the longitudinal ends of the buffer plate 11. Subsequently, the first motor 2.3.4 and the second motor 2.3.11 are started synchronously to control the rocker 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 posture of the rocker 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 transverse drive assembly, so that the roller 2.3.8 applies a lateral thrust to the longitudinal ends of the buffer plate 11 until the longitudinal ends of the buffer plate 11 are folded on the back of the buffer plate 11.

[0082] like Fig.18 and Fig.19 As shown, the third motor 3.2.5 is started, and the third motor 3.2.5 controls the first clamp 3.2.2 to move to the unloading end of the support plate 2.1. When the first clamp 3.2.2 clamps one lateral end of the buffer plate 11, the third motor 3.2.5 reversely drives the first clamp 3.2.2. During the resetting process of the first clamp 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 support the buffer plate 11 at the same time.

[0083] like Fig.19 and Fig. 20 As shown, the fourth motor 3.3.13 is started, and the fourth motor 3.3.13 controls the third movable platform 3.3.2 to move above the packaging cushion 10. The third cylinder 3.3.5 is started, and the third cylinder 3.3.5 controls the third mounting plate 3.3.3 to move downward. When the pressing plate 3.3.4 contacts the buffer plate 11 and the flexible pressing block 3.3.7 contacts the packaged object 20, the second cylinder 3.1.8 is started synchronously, so that the buffer plate 11 and the second slide rail 3.1.2 move downward synchronously. During the downward movement, the two lateral ends of the buffer plate 11 are blocked by the first slide rail 3.1.1 and the third slide rail 3.1.3 and folded upward until the two lateral ends of the buffer plate 11 are folded on both sides of the packaged object 20.

[0084] like Fig.21 and Fig. 22As shown, keep the position of the third mounting plate 3.3.3 unchanged, start the clamping claw cylinder 3.3.9, and the clamping claw cylinder 3.3.9 controls the second clamping claw 3.3.8 to move downward. After the second clamping claw 3.3.8 clamps the lateral ends of the buffer plate 11, the clamping claw cylinder 3.3.9 controls the second clamping claw 3.3.8 to move upward, and the third cylinder 3.3.5 controls the third mounting plate 3.3.3 to move upward until the packaging cushion 10 is separated from the slide rail 3.1. Then start the fourth motor 3.3.13, and the fourth motor 3.3.13 controls the third movable platform 3.3.2 to move, so that the folded packaging cushion 10 can be moved to the next station together with the packaged object 20. After the folded packaging cushion 10 is delivered to the specified position, the second folding and forming mechanism 3.3 can be reset.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification should be included in the scope of protection of this application.

[0086] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
