[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-10 As shown, a suspended conveyor system for packaging carton production includes: The guide rail includes inclined portions 11 distributed at both ends of the horizontal portion 1; A load carriage 2 is slidably mounted on the guide rail and is transmitted via a chain, wherein at least two relatively movable claws are movably mounted on the load carriage 2; The sling 5 has hanging plates 51 symmetrically fixedly mounted on its top, and a track groove is formed between the two hanging plates 51 . A clamping groove 52 is opened on the adjacent side of the two hanging plates 51 , and the clamping claws are embedded in the clamping groove 52 when they are synchronously extended.

[0022] Specifically, multiple rollers 21 rotatably arranged on the load slide 2 are movably arranged on opposite sides of the horizontal part 1 and the inclined part 11. A conveyor chain is fixedly installed on the load slide 2, and the frequency conversion speed regulation motor in the conveyor drives the sprocket to rotate, and then the sprocket and the conveyor chain on the load slide 2 are engaged to pull the chain to move, thereby driving the load slide 2 to move along the horizontal part 1 and the inclined part 11 to load and unload materials.

[0023] The hanging plate 51 is fixedly welded to the top of the sling 5, and is symmetrically arranged through the claws, and the two claws move relative to each other on the load slide 2 along the same axis. When the load slide 2 slides along the inclined portion 11 toward the horizontal portion 1 and finally slides onto the horizontal portion 1, the two claws move synchronously relative to each other to approach and disengage from the slots 52, thereby unlocking and disengaging the load slide 2 and the sling 5. At this time, the movable sling 5 can be separately loaded with packaging cartons on the ground, and the new sling 5 that has been loaded can be arranged on the moving path of the load slide 2 for unloading and below the horizontal portion 1. When the two claws disengage from the previous unloading sling 5, as the load slide 2 moves, the two claws are quickly located between the track grooves on the newly loaded sling 5, and then the two claws are synchronously extended again to be embedded in the slots 52 to complete the rapid clamping and locking.

[0024] Therefore, by moving the load slide 2 and locking the claw, continuous unloading and loading operations of the sling 5 can be achieved without stopping the load slide 2, thereby eliminating the problem of traditional manual unhooking difficulties, and correspondingly ensuring that the claw can be accurately locked into the slot 52.

[0025] The two claws can be extended synchronously to fit into the slot 52 by an electric push rod in conjunction with a connecting rod; or a corresponding guide member can be provided on the guide rail, and a guide rod can be slidably provided on the load slide 2 to move on the guide member, and then the guide rod can be cooperated with the connecting rod to squeeze the two claws to slide and fit into the slot 52; or any method known to those skilled in the art to drive the two claws to extend synchronously to fit into the slot 52 is available.

[0026] In the above technical solution, when the load slide 2 is unloading and loading along the horizontal portion 1 and the inclined portion 11 on the guide rail, it is equipped with two relatively movable claws, and then when the sling 5 hoisted on the load slide 2 is unloading, the two claws are disengaged from the slots 52 to complete the rapid unloading, and at the same time, the two claws are used to re-engage the slots 52 on another sling 5 to quickly complete the unloading and loading operations of the sling 5, thereby improving the efficiency of conveying and transporting packaging cartons.

[0027] As an embodiment further provided by the present invention, the claw is rotatably mounted.

[0028] Specifically, the two claws can rotate synchronously on the load slide 2, so that the two claws can be embedded in the slots 52 on the adjacent sides of the two hanging plates 51 through the synchronous relative rotation of the two claws to achieve the clamping and locking of the sling 5.

[0029] Furthermore, the slots 52 can extend to the top of the hanging plate 51 , and then the two claws can be swung in the vertical direction to achieve a clamping operation on the slots 52 on the two hanging plates 51 , thereby achieving a clamping and fixing operation on the sling 5 .

[0030] Furthermore, the number of the clamping claws can be four and divided into two groups, and the clamping slots 52 are through the hanging plate 51, and each hanging plate 51 is provided with two clamping slots 52, and then the clamping claws are flipped along the outer sides of the two hanging plates 51 into the clamping slots 52, so as to utilize the two groups of clamping claws to simultaneously realize the operation of clamping the sling 5, or the two groups of clamping claws are flipped along the inner sides of the two hanging plates 51 into the clamping slots 52, so as to facilitate the operator to realize quick hooking.

[0031] Furthermore, the driving method for driving the clamping claw to flip for clamping can be an operator who drives the clamping claw hingedly mounted on the load slide 2 to flip for clamping by an electric push rod in conjunction with a connecting rod; or an operator who drives the operator to flip the clamping claw hingedly mounted on the load slide 2 by the electric push rod and the connecting rod; or an operator who drives the operator to flip the clamping claw synchronously to clamp the clamping claw by using a motor in conjunction with two meshing gears.

[0032] As another embodiment provided by the present invention, the two claws are divided into a bottom ring 4 and a top ring 43. The outer wall of the bottom ring 4 is fixedly and symmetrically mounted with a first rod 41, and the outer wall of the top ring 43 is fixedly and symmetrically mounted with a second rod 44. The first rod 41 and the second rod 44 are staggered to form an X shape, and when the angle between the first rod 41 and the second rod 44 is the largest, they are respectively embedded in the slot 52.

[0033] Specifically, the bottom of the load carriage 2 is symmetrically fixedly welded with shield plates 22, the bottom of the two shield plates 22 is fixedly mounted with bottom plates 23, and the bottom ring 4 is rotatably arranged on the top of the bottom plate 23 and located between the two shield plates 22, and the top ring 43 is rotatably arranged on the bottom ring 4 and moves between the two shield plates 22, as shown in FIG. Figure 6 As shown, the adjacent outer walls of the two shields 22 are respectively fixedly welded with limiting plates 26, which limit the positions of the top ring 43 and the bottom ring 4. Figure 3 As shown, the structure of the bottom ring 4 and the top ring 43 is as follows: Figure 4As shown, after the top ring 43 and the bottom ring 4 rotate relative to each other, the first rods 41 and the second rods 44 are interlaced in an X-shape and at their maximum angle. In this state, the two first rods 41 on the bottom ring 4 and the two second rods 44 on the top ring 43 form a symmetrical four-point support. Compared to traditional hook-type structures that are prone to shaking, the four-point support method can reduce horizontal shaking of the sling 5 and improve the support points and supporting tension strength of the sling 5. By disengaging the first rods 41 and the second rods 44 in the X-shape from the slots 52, quick unlocking is achieved, avoiding the tedious steps of manual hanging.

[0034] The top ring 43 and the bottom ring 4 can be rotated in opposite directions relative to each other by using two motors to drive them separately; or a motor can be used in conjunction with a planetary gear set to achieve synchronous opposite rotation of the top ring 43 and the bottom ring 4; or any other method known to those skilled in the art to drive the top ring 43 and the bottom ring 4 to rotate in opposite directions relative to each other can be used.

[0035] As another embodiment provided by the present invention, a protrusion 42 is fixedly installed symmetrically on the inner wall of the bottom ring 4, and an inner block 45 is fixedly installed symmetrically on the inner wall of the top ring 43, and the distance between the protrusion 42 and the inner block 45 is the farthest when the angle between the first rod 41 and the second rod 44 is the largest.

[0036] Specifically, the bottom of the horizontal part 1 and the inclined part 11 are fixedly installed with a pad 12, which is arranged on the entire guide rail and is only disconnected at the horizontal part 1. The two ends of the pad 12 disconnected at the horizontal part 1 are provided with a ramp 13, and a pressure piece 3 is slidably provided on the load slide 2, and an auxiliary wheel 31 is rotatably provided on the top of the pressure piece 3. The guide column 32 fixedly welded at the bottom of the pressure piece 3 is movably provided between the two shielding plates 22. Further, as Figure 9 As shown, conical blocks 35 are symmetrically fixedly mounted on the outer wall of the guide pillar 32, and the conical ends of the conical blocks 35 are movably disposed between two adjacent protrusions 42 and inner blocks 45. A compression spring 28 is provided on one side of the first rod 41 and the second rod 44 of the bottom plate 23, and the compression spring 28 is fixedly mounted on the bottom plate 23. A compression spring 27 is fixedly mounted between the bottom plate 23 and the guide pillar 32.

[0037] In the default state, the compression spring plate 28 pushes the first rod 41 and the second rod 44 respectively to minimize the distance between the protrusion 42 and the inner block 45. Furthermore, when the auxiliary wheel 31 is attached to the bottom of the horizontal portion 1 and the first rod 41 and the second rod 44 are unloaded, as the load carriage 2 moves along the inclined platform 13 toward the pad 12, and the first rod 41 and the second rod 44 gradually approach the track groove between the two hanging plates 51 on the sling 5, the pressure piece 3 moves downward due to the pressure of the pad 12, and then the pressure piece 3 moves downward relative to the load carriage 2, and the compression spring 27 deforms and accumulates force. At this time, the tapered ends of the two tapered blocks 35 on the guide column 32 are respectively inserted into the two adjacent protrusions 42. and the inner block 45, and then under the extrusion of the conical block 35, the protrusion 42 and the inner block 45 are moved away from each other, and at the same time, the top ring 43 and the bottom ring 4 keep rotating synchronously in opposite directions, so that the first rod 41 and the second rod 44 are moved away from each other and the angle between them increases, and the squeezing spring plate 28 is deformed to store force. Then, when the auxiliary wheel 31 is fully active on the pad 12, the angle between the first rod 41 and the second rod 44 is the largest, and the ends of the first rod 41 and the second rod 44 are respectively embedded in the card slot 52 and staggered to form an X shape.

[0038] Therefore, through the push-pushing cooperation between the pressure piece 3 and the pad 12 on the guide rail, when the auxiliary wheel 31 gradually separates from the pad 12 and rests on the horizontal portion 1, the compression spring 27 releases its stored force to push the pressure piece 3 back to its original position, and the extrusion spring 28 releases its stored force to push the first rod 41 and the second rod 44 out of the slot 52, thereby achieving rapid unlocking. Furthermore, the load carriage 2 can quickly unlock the sling 5 and mount a new sling 5 during the entire operation, thereby improving the overall lifting and transportation efficiency of the packaging cartons, and does not require the use of a drive source such as a motor or electric push rod for loading.

[0039] As another embodiment provided by the present invention, side grooves 53 are respectively provided on opposite sides of the two hanging plates 51, and the limit blocks 6 fixedly installed on the load slide 2 extend into the side grooves 53. The limit blocks 6 are provided with arched spring plates 72 whose arc tops abut against the inner walls of the side grooves 53.

[0040] Specifically, the outer wall of the shield 22 is fixedly welded with a support plate 24, and a connecting frame 25 is fixedly installed on the support plate 24 by bolts, the limit block 6 is fixedly welded to the connecting frame 25, and a receiving cavity 61 is provided on the limit block 6. A window 62 communicating with the receiving cavity 61 is provided on the top of the limit block 6. The arched spring plate 72 is fixedly welded in the receiving cavity 61, and the arc top of the arched spring plate 72 extends along the window 62 and fits on the inner wall of the side groove 53. Therefore, when the limit block 6 moves with the load slide 2, the two limit blocks 6 and the connecting frame 25 are located on the opposite side of the two hanging plates 51, thereby achieving a certain degree of support for the hanging plates 51. The limit function reduces the problem of the sling 5 shaking during lifting, which may cause the stacked cartons inside to become loose, thereby improving the stability of the sling 5. At the same time, when the first rod 41 and the second rod 44 move between the two hanging plates 51, the arc top of the arch spring plate 72 is attached to the inner wall of the side groove 53, and a certain distance is maintained between the limit block 6 and the top inner wall of the side groove 53. When the sling 5 shakes in the vertical direction, the arch spring plate 72 is used to cushion the vibration, thereby avoiding the problem of cartons scattering caused by the large-scale vibration of the sling 5 during suspended transportation, and further improving the stability of the sling 5 during lifting.

[0041] As the best embodiment provided by the present invention, snake-shaped spring plates 7 are fixedly mounted at both ends of the arch spring plate 72 , with the ends thereof abutting against the limit block 6 .

[0042] Specifically, the two serpentine spring plates 7 are respectively fixedly welded to the ends of the arch spring plate 72, and the S-shaped serpentine spring plates 7 are arranged to be coiled in the vertical direction. Therefore, when the limit block 6 is located in the side groove 53, the two serpentine spring plates 7 are simultaneously forced upward, thereby driving the arch spring plate 72 to further push against the inner wall of the side groove 53, thereby increasing the distance between the limit block 6 and the top inner wall of the side groove 53, thereby increasing the buffer distance and utilizing the arch spring plates 72 and the serpentine spring plates 7 to simultaneously increase the upward prestress on the sling 5. Moreover, when the sling 5 is subjected to downward force due to pulling relative to the load slide 2, the combined deformation of the two serpentine spring plates 7 and the arch spring plate 72 buffers the instantaneous force acting on the sling 5, thereby preventing the sling 5 from becoming unstable due to large-scale shaking and the packaging carton materials from becoming loose.

[0043] By adopting the method of simultaneously forcing the two serpentine spring plates 7 to move upward and drive the arch spring plate 72 to move upward, when the limit block 6 enters the side groove 53, the arch spring plate 72 can be located in the limit block 6 to avoid the problem of the protruding limit block 6 causing the sling 5 to be pushed and displaced by the force. Therefore, when the limit block 6 reaches the predetermined position in the side groove 53, for example, the middle area in the side groove 53, the two serpentine spring plates 7 are simultaneously forced to move upward to push the arch spring plate 72 to protrude from the top of the limit block 6 to fit on the inner wall of the top of the side groove 53 for prestressed support.

[0044] The two serpentine spring plates 7 can be forced to move upward at the same time by using a motor in conjunction with a gear rack and a top plate to drive the two serpentine spring plates 7 to move upward at the same time; or an electric push rod and a top plate can be used to push the two serpentine spring plates 7 upward at the same time; or any method known to those skilled in the art to drive the two serpentine spring plates 7 to move upward at the same time can be used.

[0045] As another embodiment provided by the present invention, a squeeze plate 73 is symmetrically rotated and provided on the limit block 6, and the squeeze plate 73 is turned over to push the two serpentine spring plates 7 to reduce the distance between them.

[0046] Specifically, the two extrusion plates 73 are symmetrically hinged on the limit block 6, and in the default state, the extrusion plates 73 are pushed by the arched spring plate 72, and the top ends of the extrusion plates 73 are attached to the limit block 6 to keep the extrusion plates 73 in a vertical state.

[0047] When the limit block 6 moves to the middle area of ​​the side groove 53 with the load slide 2, the two serpentine spring plates 7 are forced to move upward at the same time, driving the arch spring plate 72 to move up and fit against the inner wall of the top of the side groove 53, and then the two extrusion plates 73 are flipped to one side of the serpentine spring plate 7 to squeeze the serpentine spring plate 7 at the same time. At this time, the distance between the two serpentine spring plates 7 is reduced, and the two serpentine spring plates 7 are moved closer to compress the arch spring plate 72 to deform. Therefore, when the two ends of the arch spring plate 72 are moved closer, the arc top on it further contacts the inner wall of the side groove 53 to enhance the upward prestress of the sling 5, thereby improving the supporting strength of the sling 5 and further expanding the buffering distance between the limit block 6 and the inner wall of the side groove 53.

[0048] The two extrusion plates 73 can be flipped simultaneously by a motor and two meshing gears; or by two electric push rods pushing them respectively; or by any other method known to those skilled in the art to drive the two extrusion plates 73 to flip simultaneously.

[0049] As another embodiment provided by the present invention, a diagonally distributed limiting member 54 is fixedly installed on the top of the sling 5, and the stretcher 8 hingedly arranged on the limiting block 6 is plugged into the limiting member 54 when the angle between the first rod 41 and the second rod 44 is maximum.

[0050] Specifically, a double support plate group 63 is symmetrically fixedly welded to the outer wall of the limit block 6 on the side opposite to the hanging plate 51, and the carrying rod 8 is hingedly arranged between the double support plate groups 63. An anti-shifting plate 83 is fixedly installed on one end of the carrying rod 8 opposite to the limit block 6, and a curved surface portion 82 is provided on the side of the carrying rod 8. The limit members 54 are respectively fixedly welded to the top of the sling 5, and the opening side of the limit members 54 is respectively oriented towards the swing direction of the carrying rod 8. A special-shaped spring plate 55 is fixedly installed in the limit member 54, wherein the special-shaped spring plate 55 includes a downwardly inclined inclined surface provided on the side facing the swing direction of the carrying rod 8.

[0051] Therefore, when the load carriage 2 moves to the track groove between the two hanging plates 51, the first rod 41 and the second rod 44 are respectively embedded in the card slot 52 when the angle between them is the largest, thereby realizing the locking mounting between the load carriage 2 and the sling 5. At this time, the limit block 6 moves to the middle area of ​​the side groove 53, as shown in FIG. Figure 7 As shown, the multiple spreaders 8 are flipped to approach the limiters 54, and then the ends of the spreaders 8 facing the limit blocks 6 are respectively inserted into the openings of the limiters 54. The curved surface 82 gradually squeezes the shaped spring plate 55 to deform. At this time, the anti-displacement plate 83 is located on the side of the limiter 54, thereby limiting the displacement of the sling 5 along the track groove, further reducing the shaking of the sling 5 during transportation. At the same time, the shaped spring plate 55 squeezes the spreaders 8 in the vertical direction to further cushion the shaking of the sling 5 in the vertical direction, thereby further improving the stability of the sling 5 during transportation.

[0052] The multiple stretchers 8 can be flipped by using motors to drive them respectively; or by using electric push rods, gears and racks respectively; or by any other method known to those skilled in the art to drive the stretchers 8 to flip.

[0053] As another embodiment further provided by the present invention, a slope slider 81 is fixedly installed on the carrying rod 8, and the serpentine spring plate 7 includes an inclined end 71, which contacts the limit block 6 and is slidably connected to the slope of the slope slider 81.

[0054] Specifically, such as Figure 8 and Figure 10 As shown, the ramp slider 81 is fixedly welded to the lever 8, and a curved surface is provided on the side of the ramp slider 81 facing the inclined end 71 of the serpentine spring plate 7. Because the inclined end 71 and the stop block 6 are in a movable and fittable state, the lever 8 is turned to cause the ramp slider 81 to press against the inclined end 71, thereby driving the serpentine spring plate 7 upward under the pressure of the ramp slider 81.

[0055] When the sling 5 is in the middle of the second stop 53, the first stop 51 is moved to the middle area of ​​the second stop 53, and then the sling 5 is rotated by the plurality of levers 8. At this time, the plurality of levers 8 are respectively inserted into the openings of the limit members 54 relative to one end of the limit block 6, and the curved surface 82 squeezes the special-shaped spring plate 55 to deform, and the anti-shift plate 83 limits the sling 5. In this state, the tilting of the lever 8 drives the slope slider 81 to tilt toward the limit block 6, and then drives the serpentine spring plate 7 to move upward under the squeezing of the slope slider 81 on the inclined end 71, and then realizes the multi-directional limitation of the sling 5 through the tilting of the lever 8, and at the same time drives the serpentine spring plate 7 to move upward to drive the arch spring plate 72 to push the inner wall of the side groove 53, thereby cooperating with the serpentine spring plate 7 and the arch spring plate 72 to enhance the buffering effect of the sling 5 in the vertical direction.

[0056] As a further optimal embodiment provided by the present invention, the extrusion plate 73 and the slope surface on the slope slider 81 are in sliding connection.

[0057] Specifically, the extrusion plate 73 uses its hinge axis as a dividing point, the top end relative to the hinge axis is a short plate, and the bottom end relative to the hinge axis is a long plate, so the short plate, the long plate and the hinge axis of the extrusion plate 73 are used to form a lever. Figure 10 As shown, a torsion spring 64 is sleeved on the hinge shaft of the stretcher 8, and the two ends of the torsion spring 64 are respectively fixedly mounted on the stretcher 8 and the double support plate group 63. In the default state, the stretcher 8 and the limit block 6 remain parallel.

[0058] Further, such as Figure 2 and Figure 8 As shown, the outer wall of the guide column 32 is symmetrically fixedly welded with a press frame 33, and the inclined plates 34 symmetrically fixedly installed on the press frame 33 are respectively movably arranged on the carrying rod 8 below it. Figure 5 and Figure 10 As shown, the bottom end of the extrusion plate 73 is located on the moving path of the ramp slider 81.

[0059] Therefore, when the load slide 2 moves along the inclined platform 13 toward the pad 12, the pressure piece 3 moves downward due to the pressure of the pad 12. At this time, the tapered ends of the two tapered blocks 35 on the guide column 32 are respectively inserted between the two adjacent protrusions 42 and the inner block 45 and squeezed, so that the first rod 41 and the second rod 44 move away from each other and are respectively embedded in the slot 52. At the same time, during the downward movement of the guide column 32, the inclined plate 34 gradually squeezes the carrying rod 8. At this time, the carrying rod 8 is squeezed to flip toward the limit piece 54, and then when the first rod 41 and the second rod 44 are embedded in the slot 52, one end of the carrying rod 8 relative to the limit block 6 is simultaneously embedded The opening on the limiter 54, and during the entire flipping process of the stretcher 8, the slope slider 81 on the stretcher 8 first squeezes the inclined end 71 to drive the serpentine spring plate 7 to move upward, and then as the stretcher 8 continues to flip, the slope slider 81 begins to gradually squeeze the bottom end of the extrusion plate 73, and then under the extrusion of the slope slider 81, the bottom ends of the two extrusion plates 73 on the limit block 6 are flipped away from the serpentine spring plate 7, and the top ends of the two extrusion plates 73 are flipped to squeeze the serpentine spring plate 7, and then under the extrusion of the two extrusion plates 73, the arc top on the arch spring plate 72 is further pressed against the inner wall of the side groove 53.

[0060] The movement of the load carriage 2 and the squeeze fit between the pressure piece 3 and the backing plate 12 allow the guide post 32 to drive the first rod 41 and the second rod 44 into the slot 52 to initially lock the sling 5. The tilting plate 34 then moves downward synchronously to squeeze and flip the spreader 8. During the flipping of the spreader 8, the serpentine spring plate 7 is driven upward and the squeezing plate 73 is driven to flip. When the spreader 8 flips to the opening located on the limiter 54, the sling 5 is further limited. Therefore, the multi-directional limit is used to improve the overall stability of the sling 5 in carrying packaging cartons.

[0061] Working principle: The load carriage 2 is fed cyclically along the guide rail. In the process of the load carriage 2 moving from the horizontal portion 1 to the inclined portion 11, the pressing piece 3 and the pad 12 are squeezed together to drive the guide post 32 to slide downward relative to the load carriage 2. As the load carriage 2 moves to the track groove, the guide post 32 moves downward and the compression spring 27 is deformed and stored, so that the tapered ends of the two tapered blocks 35 on the guide post 32 are respectively inserted between the two adjacent protrusions 42 and the inner block 45, and then the tapered block 35 Under the extrusion, the protrusion 42 and the inner block 45 are moved away from each other, and at the same time, the top ring 43 and the bottom ring 4 keep rotating synchronously in opposite directions, so that the first rod 41 and the second rod 44 are moved away from each other and the angle between them increases, and the spring plate 28 is squeezed to deform and accumulate force. Then, when the auxiliary wheel 31 is fully active on the pad 12, the angle between the first rod 41 and the second rod 44 is the largest, and the ends of the first rod 41 and the second rod 44 are respectively embedded in the card slot 52, and staggered to form an X shape to achieve the initial locking between the load slide 2 and the sling 5.

[0062] Furthermore, in the process of the guide column 32 moving downward relative to the load slide 2, the inclined plate 34 is gradually squeezed on the stretcher 8. At this time, the stretcher 8 is squeezed to flip toward the limit piece 54. One end of the stretcher 8 relative to the limit block 6 is embedded in the opening on the limit piece 54 and squeezes the special-shaped spring plate 55 to deform, and the torsion spring part 64 deforms and stores force, and then the limit piece 54 is used to further support and lift the sling 5. At the same time, the special-shaped spring plate 55 provides a certain buffer for the vertical shaking of the sling 5 during operation.

[0063] Furthermore, during the flipping of the shoulder bar 8, the sloped slider 81 on the shoulder bar 8 first squeezes the inclined end 71 to drive the serpentine spring plate 7 to move upward, and the serpentine spring plate 7 moves upward to drive the arch spring plate 72 to push the inner wall of the side groove 53, so as to cooperate with the serpentine spring plate 7 and the arch spring plate 72 to enhance the effect of further buffering the sling 5 in the vertical direction. Then, as the lifting rod 8 continues to flip, the slope slider 81 begins to gradually squeeze the bottom end of the squeezing plate 73, and then, under the squeezing of the slope slider 81, the bottom ends of the two squeezing plates 73 on the limit block 6 are flipped away from the serpentine spring plate 7, and the top ends of the two squeezing plates 73 are flipped to squeeze the serpentine spring plate 7, and then, under the squeezing of the two squeezing plates 73, the arc top of the arch spring plate 72 is further pressed against the inner wall of the side groove 53. At the same time, the push of the arch spring plate 72 expands the buffer distance between the limit block 6 and the inner wall of the side groove 53. At the same time, the limit block 6 limits the two hanging plates 51, which further improves the stability of the sling 5 during operation. Then, through multi-directional limitation, the stability of the sling 5 in lifting the packaging cartons is improved, avoiding the problem of loose packaging cartons caused by large swings during the start and stop process or vertical vibrations during operation during long-distance transportation of stacked packaging cartons.

[0064] When the pressure piece 3 on the load slide 2 is separated from the pad 12 and gradually moves to the bottom of the horizontal part 1, the compression spring 27, the extrusion spring plate 28 and the torsion spring member 64 start to release the stored force respectively, and then the compression spring 27 drives the pressure piece 3 to move up and reset relative to the load slide 2, and the extrusion spring plate 28 drives the first rod 41 and the second rod 44 to disengage and unlock from the slot 52 respectively, and the torsion spring member 64 drives the carrying rod 8 to disengage from the opening on the limit member 54 to release the limit, and the arched spring plate 72 gradually releases the pressure on the inner wall of the side slot 53 Then, when the sling 5 is completely unlocked from the load slide 2, a fence that can block the movement of the sling 5 is placed on the ground area where the sling 5 is in the unlocked position, so that the load slide 2 continues to move so that the load slide 2 is disengaged from the track groove between the two hanging plates 51, and as the load slide 2 continues to move, the load slide 2 performs the above-mentioned steps to quickly lift and lock another sling 5 that has been newly loaded with packaging cartons. In this way, the efficiency of carrying and conveying packaging cartons can be greatly improved.
