[0037] Figure 1 It is a schematic structural diagram of a flipping device according to an embodiment of the present invention.

[0038] Please refer to Figure 1 , the flipping device includes a bearing plate 100, a push plate 200, a push rod 300 and a base 400. In this embodiment, there are four push rods 300, two push rods 300 are distributed on each side of the bearing plate 100, and the push rods 300 are arranged in a cross shape on both sides of the bearing plate 100, and do not interfere with each other at the intersection. One end of the push rod 300 is connected to the bearing plate 100, and the push rod 300 can rotate around its connection, and the other end is connected to the base 400, and the push rod 300 can rotate around its connection. Applying power to the push rod 300 makes the push rod 300 rotate around the connection. Since the base 400 is fixed and is used for fixed connection with the operating table or other similar components, only the bearing plate 100 will flip under the rotation and pushing action of the push rod 300. In this embodiment, the flipping angle of the bearing plate 100 is 90 degrees, that is, the bearing plate 100 can flip from a state parallel to the horizontal plane to a state perpendicular to the horizontal plane under the action of the push rod 300. The carrying plate 100 is used to carry objects to be pressed (such as packaging boxes), and the pressing surface of the objects to be pressed is switched by turning over the carrying plate 100 .

[0039] In this embodiment, the device for applying power to the push rod 300 is a first cylinder 301, and there are two first cylinders 301, which are distributed on both sides of the carrier plate 100. The telescopic rod of the first cylinder 301 is connected to one of the two push rods 300 on both sides of the carrier plate 100, pushing the push rod 300 to rotate, thereby driving the carrier plate 100 to flip, and the remaining push rod 300 not connected to the first cylinder 301 plays a role in supporting the carrier plate 100 and limiting the flip angle of the carrier plate 100. The flip angle of the carrier plate 100 can also be limited by the stroke of the first cylinder 301. In other embodiments, the device for applying power to the push rod 300 may not be a cylinder, but may be other devices that can provide power.

[0040] In this embodiment, a push plate 200 is disposed above the carrier plate 100 and is perpendicular to the carrier plate 100. The space between the push plate 200 and the carrier plate 100 is used to place the objects to be pressed. The push plate 200 can reciprocate on the carrier plate along the horizontal plane of the carrier plate to transfer the objects to be pressed on the carrier plate 100 and transfer the objects to be pressed on the carrier plate 100 to the next station.

[0041] Specifically, the push plate 200 realizes telescopic reciprocating motion through the scissor-type telescopic structure 201, and the power source of the scissor-type telescopic structure 201 comes from the second cylinder 202 connected thereto. The scissor-type telescopic structure 201 and the second cylinder 202 are both located on the carrier plate 100, and the movable end of the scissor-type telescopic structure 201 is connected to the push plate 200, and the other end is a fixed end, which is fixedly connected to the carrier plate 100. The second cylinder 202 applies power to the scissor-type telescopic structure 201, prompting the scissor-type telescopic structure 201 to perform a scissor-like opening or closing action, and the scissor-type telescopic structure 201 then drives the push plate 200 to reciprocate. This scissor-type telescopic structure 201 has a simple structure and uses the principle of a lever, so the applied force is small, and a small power source can be selected to make the structure more compact.

[0042] Furthermore, the push plate 200 is also connected to a folding cantilever 203, one end of the folding cantilever 203 is fixedly connected to the supporting plate 100, and the other end is connected to the push plate 200, so as to support the push plate 200 and follow the push plate 200 to make a folding movement, so that the push plate 200 is suspended above the supporting plate 100, avoiding direct contact between the push plate 200 and the supporting plate 100, reducing the friction of the push plate 200 during reciprocating motion, and thereby reducing the load of the second cylinder 202.

[0043] In this embodiment, a limiting plate 101 is provided on the load-bearing plate 100, and the limiting plate 101 is arranged vertically with the load-bearing plate 100. There are two limiting plates 101, which are respectively located on both sides of the push plate 200 and are arranged oppositely. The distance between the two limiting plates 101 is greater than the length of the push plate 200, so as to avoid interference with the movement of the push plate 200. The space surrounded by the limiting plate 101, the load-bearing plate 100 and the push plate 200 is used for placing the objects to be pressed. The limiting plate 101 can prevent the objects to be pressed above the load-bearing plate 100 from falling from both sides of the load-bearing plate 100 during the transfer process. In addition, the limiting plate 101 on one side of the load-bearing plate 100 in this embodiment can move inward under the action of the third cylinder 102, and press the objects to be pressed on the load-bearing plate 100, thereby preventing the load-bearing plate 100 from throwing out the objects to be pressed during the flipping process. In other embodiments, the limiting plates 101 on both sides of the load-bearing plate 100 can move inward.

[0044] In this embodiment, a bearing base 500 is further included, and the bearing base 500 is located below the bearing plate 100 and contacts the bearing plate 100 in a horizontal state. When the object to be pressed on the bearing plate 100 is pressed, the bearing plate 100 will be subjected to pressure from the pressing mechanism. The setting of the bearing base 500 can effectively share the pressure on the bearing plate 100, and avoids the pressure on the bearing plate 100 being borne by the push rod 300 and the first cylinder 301, thereby enhancing the stability of the entire device during operation.

[0045] In this embodiment, a limit block 401 is further provided on the base 400. The limit block 401 is located on the path of the rotation interval of one of the push rods 300, and is used to limit the range of motion of the push rod 300, so as to ensure that the support plate 100 does not flip too much under the action of the push rod 300. In other embodiments, the flip angle of the support plate 100 can also be limited by setting a limit on the progress of the first cylinder 301.

[0046] like Figure 2 As shown, there are two working states of the turning device of this embodiment, namely the first state A and the second state B. When the turning device is in the first state A, the carrying plate 100 is parallel to the horizontal plane, and the push plate 200 is perpendicular to the horizontal plane, and this state is the bubble pressing state. When the turning device is in the second state B, the carrying plate 100 is perpendicular to the horizontal plane, and the push plate 200 is parallel to the horizontal plane, and this state is the transfer state.

[0047] Figure 3 Flow chart of the operating method of the flipping device embodiment of the present invention.

[0048] Please refer to Figure 3 , specifically including the following steps:

[0049] 10. The turning device receives the items to be pressed

[0050] The flipping device flips from the first state A to the second state B, and the first cylinder 301 drives the push rod 300 to push the carrier plate 100 to flip 90 degrees, so that the carrier plate 100 flips from the horizontal state to the vertical state. The flipping device receives the objects to be pressed sent from the previous station. There are multiple objects to be pressed. The objects to be pressed can be objects to be pressed that have not been pressed on all sides sent by the feeding mechanism, or objects to be pressed that have been pressed on several sides and pushed by another flipping device. Since the push plate 200 is in a horizontal state at this time, the objects to be pressed are placed on the push plate 200, and the limit plate 101 retracts inward to press and fix the side of the objects to be pressed to prevent the objects to be pressed from being thrown out when the carrier plate 100 is flipped later.

[0051] 20. The turning device turns over and presses the objects to be pressed.

[0052] The flipping device flips from the second state B to the first state A, and the first cylinder 301 retracts to drive the push rod 300 to restrain the carrying plate 100 and flip it 90 degrees, so that the carrying plate 100 flips from the vertical state to the horizontal state. At this time, the push plate is in a vertical state, and the limit plate 101 moves outward to release the object to be pressed. After the limit plate 101 is released, the object to be pressed contacts with the carrying plate 100 under its own gravity to achieve the purpose of neatness, avoiding the situation in which the subsequent foaming process is insufficient due to the uneven squeezing of the object to be pressed by the limit plate 101. After neatness, the foaming mechanism foams the object to be pressed.

[0053] 30. Turning device to transfer the pressed items

[0054] After the bubble pressing operation of the object to be pressed is completed, the push plate 200 pushes the object to be pressed to the next station, which may be another turning device or a discharging mechanism.

[0055] To summarize, the flipping device embodiment provided by the present invention is used for turning over the objects to be pressed, and the flipping is achieved by driving the supporting plate through the push rod. The push rod has both pushing and supporting functions, so the flipping structure has good stability, and the stroke of the push rod can control the flipping angle of the supporting plate, thereby improving the flipping accuracy of the flipping device during the flipping process, and avoiding the problem of inefficient transmission of objects between flipping angles due to low flipping angle accuracy. In addition, the supporting plate does not rotate around a fixed rotation axis during the flipping process, so the objects to be pressed are less affected by centrifugal force during the flipping process, and the objects to be pressed are more stable during the flipping process.

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
