[0025] The present invention will be described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-6 As shown, the present invention provides an external pull-type automatic box-covering device, comprising: A frame 1 is provided with a lifting platform 11, and the lifting platform 11 can move up and down relative to the frame 1; The external pulling mechanism 2 includes a plurality of external pressure positioning members 23, a plurality of external pulling members 21, and an external pressure driving member 24. The external pressure positioning members 23 are provided with external pressure positioning surfaces 231, and the external pulling members 21 are provided on the external pressure positioning members 23. The external pressure driving member 24 is configured to drive the plurality of external pressure positioning members 23 to move closer to or away from each other. The external pressure positioning members 23 are configured to abut against the outer wall of the goods to be packaged 100 via the external pressure positioning surface 231 to position the external pulling member 21 and the goods to be packaged 100. The external pulling member 21 is configured to hook the inner wall of the enclosure 200 and apply an outward pulling force to the inner wall of the enclosure 200. The external pulling mechanism 2 is configured to hook the enclosure 200 via the plurality of external pulling members 21 to support and shape the enclosure 200. The plurality of external pressure positioning members 23 can move laterally relative to the lifting platform 11 , and the external pressure driving member 24 is disposed on the lifting platform 11 .

[0027] Specifically, during use, the rack 1 will be fixedly installed on the ground at the packaging site, so that the rack 1 plays a supporting role.

[0028] A lifting platform 11 that can move up and down is provided on the frame 1, so that the lifting platform 11 can drive the external pulling mechanism 2 installed thereon to move up and down relative to the frame 1.

[0029] The external pulling mechanism 2 is equipped with a plurality of external pressure positioning members 23 for positioning the outer surface of the goods 100 to be packaged. The external pulling member 21 hooks the inner wall of the enclosure 200 to support and shape the enclosure 200. The external pressure driving member 24 drives the external pressure positioning members 23 and the external pulling member 21 to move closer to and away from each other. In order to shape the enclosure 200, the external pulling members 21 move closer to each other, so that the enclosure 200 can be placed on the external pulling member 21. Then, under the drive of the external pressure driving member 24, the plurality of external pressure positioning members 23 move away from each other, so that the plurality of external pulling members 21 move away from each other, and the enclosure 200 is then pulled by the plurality of external pulling members 21 to shape the enclosure 200.

[0030] After the enclosure 200 is placed on the external tensioning member 21 and the lifting platform 11 is lowered to the appropriate position, the external pressure positioning members 23 are arranged on the outside of the cargo 100. Then, driven by the external pressure driving member 24, the multiple external pressure positioning members 23 are moved toward the cargo 100. The external pressure positioning surfaces 231 of the external pressure positioning members 23 gradually come into contact with the outer wall of the cargo 100 to be packaged (for example, the external pressure positioning surfaces 231 of the four external pressure positioning members 23 respectively contact the front, rear, left, and right outer walls of the cargo 100). The external pressure positioning surfaces 231 of the external pressure positioning members 23 are precisely positioned on the outer wall of the cargo 100 through the limiting effect of the outer wall of the cargo 100.

[0031] In this way, the relative position between the external tension member 21 set on the external pressure positioning member 23 and the cargo 100 can be maintained accurately. The enclosure 200 is shaped and supported by the external tension member 21. After being positioned by the external pressure positioning member 23, the lifting platform 11 will drive the external tension mechanism 2 to continue to move downward so that the enclosure 200 is wrapped around the outside of the cargo 100.

[0032] In order to achieve smooth lifting of the lifting platform 11, a first lifting drive assembly 12 is provided on the frame 1. The first lifting drive assembly 12 is used to drive the lifting platform 11 to move up and down on the frame 1 as needed. The first lifting drive assembly 12 can be implemented in a conventional lifting drive manner. For example, the first lifting drive assembly 12 can include a motor and a transmission mechanism. The power output from the motor's rotating shaft is transmitted to the lifting platform 11 through the transmission mechanism to achieve driving. The transmission mechanism can include sprockets arranged vertically and chains wound around the sprockets. The lifting platform 11 is fixedly connected to the chains. The motor is connected to the sprockets through a reducer. The sprockets rotate to drive the lifting platform 11 up and down through the chains. Alternatively, the transmission mechanism can include a screw. The lifting platform 11 is provided with a threaded hole. The screw is rotatably provided on the frame 1 and arranged vertically. The screw is threadedly connected to the threaded hole of the lifting platform 11. The motor is connected to the screw through a reducer. The screw rotates to drive the lifting platform 11 up and down. Here, there is no limitation on the specific implementation of the first lifting drive assembly 12.

[0033] In one embodiment, the external pulling member 21 is slidably disposed on the external pressure positioning member 23; the external pulling mechanism 2 includes an external pulling driving member 22, which is disposed on the external pressure positioning member 23, and the external pulling driving member 22 is configured to drive multiple external pulling members 21 to approach or move away from each other.

[0034] Specifically, the external tension member 21 is used to support and shape the enclosure 200. The external tension member 21 can move with the external pressure positioning member 23 to achieve the movement of multiple external tension members 21 toward and away from each other. When multiple external tension members 21 are relatively close together, it is convenient to place the enclosure 200 on the external tension member 21; when multiple external tension members 21 are relatively far apart, the enclosure 200 can be pulled outward by the external tension member 21 to shape it. However, after the enclosure 200 is placed on the external tension member 21, it still needs to be positioned in conjunction with the cargo 100 through the external pressure positioning member 23. During the positioning process, it is necessary to drive the various external pressure positioning members 23 away from each other so that the external pressure positioning members 23 can be distributed outside the cargo 100. At this time, the external tension members 21 will also move away from each other following the external pressure positioning member 23, and the enclosure 200 on the external tension member 21 may be pulled and damaged.

[0035] To this end, the external pulling driving member 22 is used to drive the external pulling member 21 to move on the external pressure positioning member 23 to solve the technical problem that the enclosure 200 is easily broken by being pulled.

[0036] Specifically, the external pull drive 22 first drives the multiple external pull members 21 toward each other, so that the enclosure 200 is supported on the external pull members 21. During the process of the external pull mechanism 2 supporting the enclosure 200 and positioning it with the cargo 100 via the external pressure positioning member 23, even if the external pressure positioning member 23 drives the external pull members 21 away from each other, the external pull members 21 have been moved toward each other in advance, thus preventing the enclosure 200 from being damaged by the pulling.

[0037] After the external pressure positioning member 23 and the cargo 100 are positioned, the external pulling drive member 22 drives the multiple external pulling members 21 away from each other, thereby shaping the enclosure 200 through the multiple external pulling members 21. Then, the lifting platform 11 drives the external pulling mechanism 2 to move downward as a whole, completing the installation of the enclosure 200 on the outside of the cargo 100.

[0038] During actual use, after the external pressure positioning member 23 completes the positioning with the cargo 100, in order to avoid the friction between the external pressure positioning member 23 and the cargo 100 affecting the smoothness of operation during the process of the external pulling mechanism 2 following the descent of the lifting platform 11, after the external pressure positioning member 23 cooperates with the cargo 100 for positioning, under the driving action of the external pressure driving member 24, the external pressure positioning member 23 will leave the cargo 100 by a set distance (for example: after the external pressure positioning member 23 is attached to the surface of the cargo 100, it moves outward by 1CM so that the external pressure positioning surface 231 of the external pressure positioning member 23 does not contact the cargo 100). In this way, when the lifting platform 11 moves downward, the external pressure positioning member 23 will not generate friction with the outer surface of the cargo 100. The external pressure positioning member 23 may be provided with a position switch to determine whether the external pressure positioning member 23 is in contact with the cargo 100. When the position switch is triggered by contact with the cargo 100, it is determined that the external pressure positioning member 23 is in contact with the cargo 100. The controller (such as a PLC, etc.) configured for the external pull-type automatic box-covering equipment receives the signal from the position switch and controls the external pressure driving member 24 to drive the external pressure positioning member 23 to move in the reverse direction by a set distance.

[0039] Among them, the external pulling drive member 22 includes a plurality of telescopic cylinders, which are connected to the corresponding external pulling members 21. Specifically, during use, the telescopic cylinder is first extended to allow the multiple external pulling members 21 to approach each other, thereby facilitating the placement of the enclosure 200 on the multiple external pulling members 21. After the external pressure positioning member 23 is positioned with the cargo 100, the telescopic cylinder retracts to tighten and shape the enclosure 200 through the multiple external pulling members 21. In addition, since the enclosure 200 is pulled to the inner wall by the multiple external pulling members 21, during the process of putting the enclosure 200 on the outside of the cargo 100, under the external pulling action of the external pulling members 21, it is ensured that the enclosure 200 can be reliably put on the outside of the cargo 100.

[0040] In addition, a chamfered structure 210 is provided on the lower edge of the outer surface of the outer tension member 21 .

[0041] Specifically, the chamfered structure 210 of the outer pulling member 21 is designed so that when the outer pulling member 21 drives the enclosure 200 to move downward, after it comes into contact with the cargo 100 at an angle, the chamfered structure 210 can be used for guidance to reduce the possibility of the outer pulling member 21 being stuck on the upper edge of the cargo 100, which is more conducive to improving reliability of use.

[0042] In one embodiment, the external pressure driving member 24 includes a first driving member 241 and / or a second driving member 242; The first driving member 241 is configured to drive the external pressure positioning member 23 to move laterally relative to the lifting platform 11 along a first direction; The second driving member 242 is configured to drive the external pressure positioning member 23 to move laterally relative to the lifting platform 11 along a second direction; The first direction and the second direction are perpendicular to each other.

[0043] Specifically, in order to accurately control the positions of the plurality of external pressure positioning members 23 , the positions may be adjusted by the first driving member 241 and / or the second driving member 242 .

[0044] The first driving member 241 can drive multiple external pressure positioning members 23 to approach and move away from each other along the first direction, while the second driving member 242 can drive multiple external pressure positioning members 23 to approach and move away from each other along the second direction. In this way, the external pressure positioning members 23 can be more effectively and accurately attached to the surface of the cargo 100 for positioning processing.

[0045] In one embodiment, the two ends of the lifting platform 11 are respectively provided with slidable first sliding frames 111 , and the two sides of each first sliding frame 111 are respectively provided with slidable second sliding frames 112 ; The first driving member 241 is disposed on the lifting platform 11 , and the first driving member 241 is configured to drive the two first sliding frames 111 to move closer to or away from each other along a first direction; The second driving member 242 is disposed on the corresponding first sliding frame 111 , and the second driving member 242 is configured to drive the two second sliding frames 112 on the corresponding first sliding frame 111 to move toward or away from each other along a second direction; The external pressure positioning member 23 is provided on each of the second sliding frames 112 .

[0046] Specifically, for example, an external-pull automatic box-fitting device equipped with four external-pressure positioning members 23 is provided. Accordingly, each external-pressure positioning member 23 is provided with an external-pull member 21. Thus, the lifting platform 11 is provided with four second sliding frames 112 that can move toward and away from each other to meet the installation requirements of the four external-pressure positioning members 23.

[0047] The first driving member 241 drives the two first sliding frames 111 toward or away from each other, and the second driving member 242 disposed on each second sliding frame 112 drives the corresponding two second sliding frames 112 toward or away from each other.

[0048] The first drive member 241 may include a first motor 2411 and a first lead screw 2412. The first lead screw 2412 is rotatably mounted on the lifting platform 11. The first motor 2411 is connected to the first lead screw 2412 via a speed reducer. The two ends of the first lead screw 2412 are threadedly connected to corresponding threaded holes on the first sliding frame 111. During operation, the first motor 2411 rotates forward, driving the two first sliding frames 111 toward each other via the first lead screw 2412. Conversely, the first motor 2411 rotates backward, driving the two first sliding frames 111 away from each other via the first lead screw 2412.

[0049] Similarly, the second drive member 242 may include a second motor 2421 and a second lead screw 2422. The second lead screw 2422 is rotatably mounted on the first carriage 111. The second motor 2421 may be coupled to the second lead screw 2422 via a speed reducer. The two ends of the second lead screw 2422 are threadedly engaged with corresponding threaded holes on the second carriage 112. During operation, the second motor 2421 rotates forward, driving the two second carriages 112 toward each other via the second lead screw 2422. Conversely, the second motor 2421 rotates reversely, driving the two second carriages 112 away from each other via the second lead screw 2422.

[0050] The four external pressure positioning members 23 are configured to position the four corners of the cargo 100, thereby further improving positioning accuracy. To increase the contact area between the external pressure positioning members 23 and the cargo 100, the external pressure positioning members 23 are provided with vertically extending positioning portions 232. The positioning portions 232 have an L-shaped cross-section, forming L-shaped external pressure positioning surfaces 231 on the external pressure positioning members 23, which better cooperate with the corners of the cargo 100 for precise positioning.

[0051] In some embodiments, in order to adapt to the posture of the cargo 100 for positioning when the cargo 100 is skewed, the lifting platform 11 is further provided with a first guide rail 113, on which a first adaptive slide 114 is slidably provided; the first adaptive slide 114 is provided with a first slide rail 115, the first sliding frame 111 is slidably provided on the first slide rail 115, and the first driving member 241 is provided on the first adaptive slide 114; The first sliding frame 111 is provided with a second guide rail 116, and a second adaptive slide 117 is slidably provided on the second guide rail 116; a second slide rail 118 is provided on the second adaptive slide 117, and the second sliding frame 112 is slidably provided on the second slide rail 118, and the second driving member 242 is provided on the second adaptive slide 117; The first guide rail 113 and the second guide rail 116 are arranged perpendicular to each other.

[0052] Specifically, for the goods 100 transferred to the bottom of the lifting platform 11, the placement position of the goods 100 is not in the center position below the lifting platform 11. Therefore, in order to enable multiple external pressure positioning parts 23 to effectively stick to the surface of the goods 100 for positioning, a first adaptive slide 114 and a second adaptive slide 117 are configured to adapt to the situation where the goods 100 are not positioned correctly.

[0053] Specifically, after the cargo 100 is placed beneath the lifting platform 11, the external pressure driver 24 moves the multiple second slides 112 away from each other during positioning, ensuring that after the lifting platform 11 descends, the external pressure positioning members 23 are located outside the cargo 100. Driven by the external pressure driver 24, the first slides 111 and the second slides 112 move closer together, causing the external pressure positioning members 23 to gradually approach the cargo 100.

[0054] The first guide rail 113 is arranged to extend along a first direction, and the second guide rail 116 is arranged to extend along a second direction.

[0055] Taking the first sliding frames 111 approaching each other as an example, in the process of the two first sliding frames 111 approaching each other, when the cargo 100 deviates and approaches the first sliding frame 111 on one side, the external pressure positioning member 23 close to the cargo 100 side will first rest against the surface of the cargo 100, while the external pressure positioning member 23 on the other side has not yet rested on the cargo 100. At this time, the first driving member 241 will continue to drive the two first sliding frames 111 approaching each other, so that the first adaptive slide 114 slides on the first guide rail 113, and finally the cargo 100 is clamped between the external pressure positioning members 23 on both sides in the first direction.

[0056] Taking the second sliding frames 112 approaching each other as an example, in the process of the two second sliding frames 112 approaching each other, when the cargo 100 deviates and approaches the second sliding frame 112 on one side, the external pressure positioning member 23 close to the cargo 100 side will first rest against the surface of the cargo 100, while the external pressure positioning member 23 on the other side has not yet rested on the cargo 100. At this time, the second driving member 242 will continue to drive the two second sliding frames 112 approaching each other, so that the second adaptive slide 117 slides on the second guide rail 116, and finally the cargo 100 is clamped between the external pressure positioning members 23 on both sides in the second direction.

[0057] In this way, even if the cargo 100 is not placed at the center position directly below the lifting platform 11 , the first adaptive slide 114 and the second adaptive slide 117 can cooperate to ensure that the external pressure positioning member 23 is accurately positioned.

[0058] In one embodiment, the outer pulling member 21 includes an outer pulling member 211 , and the outer pulling member 211 includes a supporting portion 2111 and an outer pulling portion 2112 . The supporting portion 2111 is formed with a supporting surface, and the outer pulling portion 2112 is formed with an outer pulling surface. The outward pulling portion 2112 is provided on the supporting portion 2111 , and the outward pulling portion 2112 extends perpendicularly to the supporting surface of the supporting portion 2111 ; The support portion 2111 is configured to support the enclosure 200 via the support surface; The outer pulling portion 2112 is configured to abut against the inner wall of the enclosure 200 through the outer pulling surface so as to apply a pulling force toward the outer side of the enclosure 200 to the enclosure 200 .

[0059] Specifically, the pull-out member 211 of the external tensioning structure 21 can extend into the inner side of the enclosure 200 through the pull-out portion 2112 and rest against the inner wall of the enclosure 200, while the lower edge of the enclosure 200 rests against the support surface of the support portion 2111. In this way, the support portion 2111 effectively supports the enclosure 200, while the pull-out portion 2112 allows the enclosure 200 to be pulled and shaped. The pull-out portion 2112 is a plate-like structure that allows the enclosure 200 to be pulled outward while further reducing the space occupied by the pull-out portion 2112 between the enclosure 200 and the cargo 100.

[0060] In a certain embodiment, when four outer pulling members 21 are configured, the cross-section of the outer pulling surface can be an L-shaped structure to better match the corner position inside the enclosure 200.

[0061] In some embodiments, the outer pulling member 21 further includes: a pressing member 212 and a pressing driving member 213, wherein a pressing surface is formed on the pressing member 212, and the pressing surface is arranged opposite to the outer pulling surface, and a clamping space is formed between the pressing surface and the outer pulling surface; The pressing driving member 213 is configured to drive the pressing member 212 to move closer to or away from the outer pulling member 211 .

[0062] Specifically, after the outer pull member 211 is used to pull the panel 200 outward to finalize its shape, in order to prevent the panel 200 from being detached from the outer pull portion 2112 of the outer pull member 211 during the process of being put on the outside of the cargo 100, the outer pull member 21 is further provided with a pressing member 212. The pressing member 212, under the driving action of the pressing driving member 213, can clamp the panel 200 between the pressing member 212 and the outer pull portion 2112, thereby ensuring that the panel 200 can be reliably put on the outside of the cargo 100.

[0063] The pressing member 213 is provided on the support portion 2111, and the pressing member 212 can slide on the support surface of the support portion 2111. The pressing member 213 can be implemented as a device with telescopic function, such as a cylinder, and is not limited thereto.

[0064] In one embodiment, a pressing component 13 is provided on the frame 1 , and the pressing component 13 can move up and down relative to the frame 1 . The pressing component 13 is configured to press the enclosure 200 downward.

[0065] Specifically, as the outer pulling mechanism 2 pulls the panel 200 to fit over the cargo 100, when the panel 200 descends to the bottom of the cargo 100, most of the panel 200 is wrapped around the outside of the cargo 100. At this time, the outer pulling portion 2112 needs to be pulled out from between the panel 200 and the cargo 100. After the outer pulling portion 2112 is pulled out from the inner side of the panel 200, the pressing component 13 can be used to press the top of the panel 200 to press the panel 200 down into place.

[0066] To prevent the enclosure 200 from moving downward with the outer pull portion 2112 during its withdrawal, the pressing member 13 may be further provided with a clamping jaw 131 configured to clamp the upper edge of the enclosure 200. The pressing member 13 is lowered to a predetermined height, so that the clamping jaw 131 clamps the upper edge of the enclosure 200. Thus, during the process of the outer pull portion 2112 being released from the enclosure 200, the enclosure 200 is clamped by the clamping jaw 131 and does not move downward with the outer pull portion 2112.

[0067] The pressing component 13 can be moved up and down by the second lifting drive assembly 14 provided on the frame 1. The specific structural configuration of the second lifting drive assembly 14 can refer to the structural configuration of the first lifting drive assembly 12 and will not be described in detail here.

[0068] In another embodiment, the lifting platform 11 is provided with an auxiliary sleeve assembly 15, and the auxiliary sleeve assembly 15 includes a swing cylinder 151, a swing arm 152, a rotating motor 153 and a friction wheel 154. The swing arm 152 is arranged on the swing cylinder 151, and the friction wheel 154 is rotatably arranged on the swing arm 152. The rotating motor 153 is arranged on the swing arm 152 and is configured to drive the friction wheel 154 to rotate; the friction wheel 154 is configured to abut against the outer wall of the periphery and roll through the friction wheel 154 to drive the enclosure 200 to move.

[0069] Specifically, as the outer pull mechanism 2 pulls the panel 200 onto the cargo 100, when the panel 200 descends to the bottom of the cargo 100, most of the panel 200 is wrapped around the cargo 100. At this point, the outer pull portion 2112 needs to be withdrawn from between the panel 200 and the cargo 100. Before the outer pull portion 2112 is withdrawn from the inner side of the panel 200, the swing cylinder 151 drives the swing arm 152 to swing, causing the friction wheel 154 to press against the outer wall of the panel 200. The friction wheel 154 presses the panel 200 against the surface of the cargo 100, preventing the panel 200 from descending with the outer pull portion 2112 as it moves downward and disengages. After the outer pull portion 2112 is withdrawn from the inner side of the panel 200, the rotation motor 153 can be used to drive the friction wheel 154 to rotate, which, using friction, drives the panel 200 downward outside the cargo 100.

[0070] On the other hand, Figure 7 As shown, an embodiment of the present application further provides an automatic box-wrapping packaging system, comprising a robot 3 and the above-mentioned external pull-type automatic box-wrapping device; The manipulator 3 is arranged on the side of the external pull automatic box-covering equipment, and the manipulator 3 is further configured to transfer the enclosure 200 to the external pull mechanism 2 of the external pull automatic box-covering equipment.

[0071] Specifically, based on the automatic box-housing equipment described in the above embodiment, in order to realize the automatic placement of the enclosure 200, a manipulator 3 is also configured. The manipulator 3 can grasp the enclosure 200 and unfold the enclosure 200 so that the external pulling mechanism 2 can be extended into the enclosure 200 for external pulling operation.

[0072] The specific structural configuration of the manipulator 3 grabbing the enclosure 200 and unfolding the enclosure 200 for processing can refer to the structural configuration in the prior art, and no limitation or elaboration is made here.

[0073] In addition, the robot arm 3 can also automatically place the box cover of the packaging box on the top of the goods 100 to complete the automatic box cover placement action.

[0074] In addition, in order to facilitate the transportation of the goods 100 , the external pull-type automatic box-covering equipment may be further configured with a conveyor line 16 on one side of the frame 1 , and the goods 100 may be automatically transported through the conveyor line 16 .

[0075] In another aspect, an embodiment of the present application further provides a method for using the above-mentioned automatic box-wrapping packaging system, comprising: The box cover is first placed on the top of the goods to be packaged 100, and then the enclosure 200 is put downward from the top of the goods to be packaged 100 and onto the outside of the goods to be packaged 100.

[0076] Specifically, during the process of automatically putting the goods 100 into the box, the box cover can be placed on the top of the goods 100 first, and then the enclosure 200 can be put into the box from the top of the goods 100 downwards.

[0077] The specific usage methods include: First, fold the edge of the box cover, and then place the box cover on top of the goods to be packaged 100; The enclosing plate 200 is moved downward from the top of the goods to be packaged 100 , and is sleeved on the outside of the goods to be packaged 100 and wraps around the flap formed by the folded edge of the box cover.

[0078] Specifically, the four edges of the box lid are usually folded (e.g., pre-bent or indented) to facilitate folding down to form flaps that rest against the side walls of the goods 100 during the actual packaging process. When the enclosure 200 is placed on the outside of the goods 100, the enclosure 200 is placed on the outside of the flaps to more effectively improve the packaging effect.

[0079] The box cover is pre-fixed on the top of the cargo 100, and its outer contour provides a physical guide reference for the installation of the enclosure 200: during the descent process of the enclosure 200, the inner wall fits against the outer wall of the box cover, ensuring that the enclosure 200 always maintains a relatively precise position with the cargo 100, avoiding the enclosure 200 from being skewed or offset.

[0080] The lid covers the top of the cargo 100, ensuring that the panel 200 only contacts the lid during installation. This prevents the panel 200 from directly rubbing against the top surface of the cargo 100, thereby protecting the cargo 100. The lid is pre-secured to the cargo 100. After the panel 200 is installed from the top, the lid compresses the top of the panel 200, while the sealing mechanism secures the bottom, creating a "top-press, bottom-secure" closed structure. This significantly improves container installation accuracy, protects the cargo 100, enhances packaging stability, and improves efficiency.

[0081] Compared with the existing technology, the effective effect of the present application is: the external pulling mechanism can be driven to move up and down by the lifting platform, the external pulling component can be extended into the unfolded enclosure, and the enclosure can be pulled outward by multiple external pulling components to support and position the enclosure, so that the bottom opening of the enclosure can match the goods below; the external pulling component is used to directly hook the inner wall of the enclosure and apply an outward pulling force, while realizing the load-bearing and shaping of the enclosure, and cooperating with the lifting platform to move up and down, so that the enclosure on the external pulling component is put on the outside of the goods to be packaged and thus completes the box-putting action, eliminating the independent clamping components and complex support structures in traditional equipment, and realizing the integration of the "load-bearing-shaping-box-putting" functions through structural optimization, while simplifying the structure and reducing costs, taking into account operational efficiency, stability and versatility, and solving the technical problems of complex equipment structure and high manufacturing cost in the existing technology.
