[0074] A first horizontal plate 502 is fixedly mounted on the end face of the first side guardrail 5 near the upper frame 3. A first inclined plate 503 is fixedly mounted on the end of the first horizontal plate 502 away from the first side guardrail 5. The end of the first inclined plate 503 away from the first horizontal plate 502 is inclined downward. A first guide wheel 504 is provided on the first inclined plate 503. There are multiple first guide wheels 504, which are arranged along the length of the first inclined plate 503. The first guide wheels 504 are rotatably connected to the first inclined plate 503.

The reset assembly uses, but is not limited to, existing tension springs. When the middle frame 2 flips, the tension spring of the first side guardrail 5 is further stretched. When the middle frame 2 resets, the first side guardrail 5 resets under the tension of the tension spring. During this process, the second side guardrail 4 is in a vertical state.

[0077] When the upper frame 3 flips, the tension spring of the second side guardrail 4 is further stretched. When the middle frame 2 returns to its original position, the second side guardrail 4 returns to its original position under the action of the tension spring. During this process, the first side guardrail 5 is in a vertical state.

[0078] Work process:

[0079] When this solution is implemented, the item to be packaged is placed on the upper frame 3. When the item to be packaged needs to be flipped to the left, the output shaft of the first hydraulic cylinder 10 extends, causing the middle frame 2 to rotate along the first hinge shaft 101. The first side guardrail 5 rotates synchronously with the middle frame 2. The support of the upper frame 3 releases the downward pressure on the second guide wheel 404. The second side guardrail 4 rotates along the third hinge shaft 103. The second horizontal plate 402 and the second inclined plate 403 pass through the opening 202. The second side guardrail 4 contacts the ground and does not affect the operation of the item to be packaged. After the operation of the item is completed, the output shaft of the first hydraulic cylinder 10 retracts, causing the middle frame 2 to reset. The support plate 302 of the upper frame 3 contacts the second guide wheel 404 of the second inclined plate 403 and presses down the inclined plate, causing the second side guardrail 4 to reset.

[0080] When the packaged item needs to be flipped to the right, the output shaft of the second hydraulic cylinder 9 extends, causing the upper frame 3 to rotate along the second hinge shaft 102. The second side guardrail 4 rotates synchronously with the upper frame 3. The support of the upper frame 3 releases the downward pressure on the first guide wheel 504. The first side guardrail 5 rotates along the first hinge shaft 101. The first side guardrail 5 contacts the ground and does not affect the operation of the packaged item. After the packaged item is finished, the output shaft of the second hydraulic cylinder 9 retracts, causing the upper frame 3 to reset. The support plate 302 of the upper frame 3 contacts the first guide wheel 504 of the first inclined plate 503 and presses down the inclined plate, causing the first side guardrail 5 to reset.

[0081] When the device is in the flipped state, the side guardrail opposite to the flipping direction contacts the ground, which facilitates the handling of the packaged items. When the device is reset, the guardrail automatically resets, improving work efficiency.

[0082] Example 2:

[0086] A back frame 7 is provided on the lower frame 1, and the lower end of the back frame 7 is fixedly connected to the lower frame 1. The upper end of the back frame 7 bends away from the lower frame 1 to prevent the back frame 7 from scratching the packaged item when it is reset. A guide rod 702 is fixedly provided at one end of the back frame 7 near the first hinge shaft 101, and the end of the guide rod 702 away from the back frame 7 bends away from the lower frame 1. There are two guide rods 702, and a guide roller 703 is provided between the two guide rods 702. The two ends of the guide roller 703 are rotatably connected to the guide rods 702 respectively. The guide roller 703 plays a guiding role during the reset of the packaged item. The lower end of the guide rod 702 away from the back frame 7 is fixedly connected to the bottom end of the back frame 7 through a guide post 701. The guide post 701 plays a guiding role during the reset of the packaged item to prevent the guide rod 702 from scratching the packaged item. The above reset refers to the reset after flipping to the left. The back frame 7 serves to limit the position of the packaged items. In other embodiments, both ends of the back frame 7 are provided with guide rods and guide rollers 703.

[0087] The lower end of the back frame 7 is fixedly connected to the lower frame 1 via a support component 6, the length of which is greater than the length of the lower frame 1.

Multiple second through holes are evenly distributed along the length of the second tube 602, and a first bolt is installed in each of the first through holes, penetrating the first through hole. The second through hole is threadedly connected to the nut; there are two third pipe fittings 603, each installed inside the second pipe fitting 602. Each third pipe fitting 603 has a third through hole corresponding to the second through hole. These third through holes are evenly spaced along the length of the third pipe fitting 603. A second bolt is installed in each of the second through holes, passing through both the second and third through holes and threadedly connected to the nut. At the end of the third pipe fitting 603 furthest from the first pipe fitting 601, a vertically threaded hole is provided. A support foot 604 is installed in this threaded hole, and its threaded rod is threadedly connected to the third pipe fitting 603. By adjusting the relative positions of the first, second, and third pipe fittings 601 and 602, the length of the support assembly 6 can be adjusted. The support assembly 6 improves the stability of the device during use and prevents it from tipping over. Rotating the support foot 604 to bring it into contact with the ground further enhances stability.

The mounting tube is located between the drive cylinder 804 and the caster 802. When the device needs to be moved, the output shaft of the drive cylinder 804 extends, lifting the mounting plate 801 and the caster 802 to move downwards and contact the ground, at which point the device can be moved. By providing the liftable caster 802, the height of the device can be reduced for easier use. The fact that the caster 802 does not contact the ground during use improves safety.

[0093] Work process:

[0094] When this solution is implemented, the item to be packaged is placed on the upper frame 3. When the item to be packaged needs to be flipped to the left, the output shaft of the first hydraulic cylinder 10 extends, causing the middle frame 2 to rotate along the first hinge shaft 101. The first side guardrail 5 rotates synchronously with the middle frame 2. The support of the upper frame 3 releases the downward pressure on the second guide wheel 404. The second side guardrail 4 rotates along the third hinge shaft 103. The second horizontal plate 402 and the second inclined plate 403 pass through the opening 202. The second side guardrail 4 contacts the ground and does not affect the operation of the item to be packaged. After the operation of the item is completed, the output shaft of the first hydraulic cylinder 10 retracts, causing the middle frame 2 to reset. The support plate 302 of the upper frame 3 contacts the second guide wheel 404 of the second inclined plate 403 and presses down the inclined plate, causing the second side guardrail 4 to reset.

[0095] When the packaged item needs to be flipped to the right, the output shaft of the second hydraulic cylinder 9 extends, causing the upper frame 3 to rotate along the second hinge shaft 102. The second side guardrail 4 rotates synchronously with the upper frame 3, and the support of the upper frame 3 releases the downward pressure on the first guide wheel 504. The first side guardrail 5 rotates along the first hinge shaft 101. The first side guardrail 5 contacts the ground and does not affect the operation of the packaged item. After the packaged item is packaged, the material is transferred. The output shaft of the second hydraulic cylinder 9 retracts, causing the upper frame 3 to reset. The support plate 302 of the upper frame 3 contacts the first guide wheel 504 of the first inclined plate 503, pressing down the inclined plate and causing the first side guardrail 5 to reset.
