[0051] like Figure 1-Figure 6 As shown, according to the first aspect of an embodiment of the present application, a packaging box forming device 100 is provided, including a first workbench 1, a first bending module 3, a second bending module 4 and a third bending module 5. The first workbench 1 is used to place a sheet material 300, and the first workbench 1 is provided with an avoidance hole 12; the first bending module 3 is arranged below the first workbench 1 and corresponds to the avoidance hole 12, and the first bending module 3 can pass through the avoidance hole 12 to perform a first bend on the sheet material 300; the second bending module 4 is arranged on one side of the first workbench 1, and the second bending module 4 can perform a second bend on the sheet material 300; the third bending module 5 is arranged above the first workbench 1, and the third bending module 5 can perform a third bend on the sheet material 300.

[0052] like Figure 1 and Figure 2 As shown, the packaging box bending device 100 comprises a first workbench 1, a first bending module 3, a second bending module 4 and a third bending module 5. The first workbench 1 is used to place the sheet material 300, and an avoidance hole 12 is opened on the first workbench 1.

[0053] The first bending module 3 is arranged below the first workbench 1 and corresponds to the avoidance hole 12, so that the first bending module 3 can pass through the avoidance hole 12. The first bending module 3 has a first state and a second state. In the first state, the first bending module 3 is located below the avoidance hole 12. In the second state, the first bending portion 32 of the first bending module 3 passes through the avoidance hole 12, and the sheet material 300 located on the first workbench 1 is bent for the first time to form a first crease 201, and the third connection portion 208, the fourth connection portion 209, and the fifth connection portion 210 of the sheet material 300 approach the direction of the third bending module 5, so that the third connection portion 208, the fourth connection portion 209, and the fifth connection portion 210 form an angle with the second connection portion 207.

[0054] When the sheet material 300 is placed, the first connecting portion 206 will be exposed on one side of the first workbench 1. The second bending module 4 is arranged on one side of the first workbench 1. The second bending module 4 has a first state and a second state. In the first state, the second bending module 4 is located below the first workbench 1. In the second state, the second top bending portion 42 of the second bending module 4 can bend the first connecting portion 206 for a second time to form a second crease 202.

[0055] The third bending module 5 is arranged above the first workbench 1. After the sheet 300 is bent for the first time, the first bending module 3 is in the second state, the third connecting part 208, the fourth connecting part 209 and the fifth connecting part 210 will be close to the third bending module 5, and the third bending module 5 bends the sheet 300 for the third time to form a third crease 203.

[0056] Further explanation, the first bending module 3, the second bending module 4 and the third bending module 5 in the embodiment of the present application are all arranged on the first workbench 1, so the sheet 300 can be bent three times at the first workbench 1. Compared with the prior art that only one bending is performed at one station, the technical solution of the present application can improve the production cycle and improve the production efficiency; and the structure is more compact and occupies less space.

[0057] In this embodiment, the packaging box 200 bending device 100 also includes a conveying module 2, which includes a transfer mechanism and an adsorption plate 22; the adsorption plate 22 is used to adsorb the sheet material 300, and the adsorption plate 22 is arranged at the driving end of the transfer mechanism, and the transfer mechanism can drive the adsorption plate 22 to approach or move away from the first workbench 1.

[0058] like Figure 1 and Figure 2 As shown, the packaging box 200 bending device 100 further includes a handling module 2 .

[0059] Among them, the transport module 2 includes a transfer mechanism and an adsorption plate 22, the adsorption plate 22 is arranged at the driving end of the transfer mechanism, and the transfer mechanism can drive the adsorption plate 22 to approach or move away from the first workbench 1, wherein it can move towards or away from the first workbench 1 in the Z direction, and can also move towards or away from the first workbench 1 in the X direction.

[0060] To further explain, the adsorption plate 22 can adsorb the sheet material 300 and transport the sheet material 300 to the first workbench 1 through the transfer mechanism.

[0061] In one embodiment, the packaging box forming device 100 also includes a pressing block, wherein the pressing block is used to press the sheet material 300 onto the first workbench 1 to prevent the sheet material 300 from being offset when the first bending module 3, the second bending module 4 and the third bending module 5 bend the sheet material 300.

[0062] In one embodiment, the first workbench 1 has a pressing area 11 , the avoidance hole 12 is located at one side of the pressing area 11 , and the adsorption plate 22 approaches the first workbench 1 and presses the sheet material 300 in the pressing area 11 .

[0063] like Figure 1 As shown, the first workbench 1 includes a clamping area 11. When the adsorption plate 22 transports the sheet material 300 to the first workbench 1, it is directly clamped in the clamping area 11. The sheet material 300 is clamped on the first workbench 1 by the adsorption plate 22, thereby preventing the sheet material 300 from deflecting when bending.

[0064] In this embodiment, the packaging box forming device 100 also includes a second workbench 8, a fourth bending module 6 and a sealing module 7. The second workbench 8 is used to place the sheet material 300 after being bent on the first workbench 1; the fourth bending module 6 is arranged on one side of the second workbench 8, and the fourth bending module 6 can bend the sheet material 300 for the fourth time; the sealing module 7 is arranged on the other side of the second workbench 8, and the sealing module 7 is used to seal the sheet material 300 that is bent for the fourth time.

[0065] like Figure 1 and Figure 2 As shown, the packaging box forming device 100 also includes a second workbench 8 , a fourth bending module 6 and a sealing module 7 .

[0066] The second workbench 8 is used to place the sheet material 300 on which the first fold 201, the second fold 202 and the third fold 203 are completed on the first workbench 1. The sealing module 7 is arranged on the second workbench 8, and the sealing module 7 and the fourth bending module 6 are respectively arranged on two opposite sides of the second workbench 8. The sheet material 300 is bent for the fourth time by the fourth bending module 6, and the sealing module 7 seals the sheet material 300 after the fourth bending.

[0067] Therefore, the packaging box forming device 100 in the embodiment of the present application only needs two workbenches and can complete the bending work of the packaging box 200 after one transport, thereby improving the work rhythm and work efficiency.

[0068] In this embodiment, the first workbench 1 and the second workbench 8 are spaced apart in the X direction; the transfer mechanism includes a first driving mechanism 21 moving along the Z direction and a second driving mechanism 9 moving along the X direction, the first driving mechanism 21 is arranged at the moving end of the second driving mechanism 9, and the adsorption plate 22 is arranged at the moving end of the first driving mechanism 21, and the conveying module 2 can transfer the sheet material 300 from the first workbench 1 to the second workbench 8.

[0069] like Figure 1 As shown, the first workbench 1 and the second workbench 8 are spaced apart along the X direction. The transfer mechanism includes a first drive mechanism 21 and a second drive mechanism 9 .

[0070] Among them, the first driving mechanism 21 includes a guide rail, a slider and a motor arranged along the Z direction, the adsorption plate is connected to the slider of the first driving mechanism 21, and the motor of the first driving mechanism 21 can drive the adsorption plate to move along the guide rail of the first driving mechanism 21 in the Z direction; the second driving mechanism 9 includes a guide rail, a slider and a motor arranged along the X direction, and the motor of the second driving mechanism 9 can drive the slider of the second driving mechanism 9 to move along the guide rail of the second driving mechanism 9 in the X direction. The first driving mechanism 21 is connected to the slider of the second driving mechanism 9, so the motor of the second driving mechanism 9 can drive the first driving mechanism 21 to move along the guide rail of the second driving mechanism 9 in the X direction.

[0071] The sheet material 300 on the first workbench 1 can be transferred to the second workbench 8 through the second driving mechanism 9, the first driving mechanism 21 and the suction plate 22. Therefore, the suction plate 22 has multiple functions, which can be used to press the sheet material 300 when the sheet material 300 is bent for the first time, the second time and the third time; and can also transfer the sheet material 300 to the second workbench 8 after the sheet material 300 completes the first time, the second time and the third time.

[0072] In this embodiment, the packaging box bending device 100 also includes a positioning module 10 and a limiting module, the positioning module 10 includes a first driving member 102 and a second limiting plate 101, the first driving member 102 can drive the second limiting plate 101 to approach or move away from the first workbench 1 in the Y direction, the limiting module includes a first limiting plate 401 and a third limiting plate 402, the first limiting plate 401 and the third limiting plate 402 are arranged on two adjacent sides of the first workbench 1, and the positioning module 10 and the first limiting plate 401 are arranged on two opposite sides of the first workbench 1.

[0073] like Figure 4 As shown, the packaging box bending device 100 further includes a positioning module 10 and a limiting module.

[0074] Among them, the limiting module includes a first limiting plate 401 and a third limiting plate 402. The first limiting plate 401 and the third limiting plate 402 are arranged on two adjacent sides of the first workbench 1. When the sheet 300 is placed on the first workbench 1, the first limiting plate 401 and the third limiting plate 402 will limit the positions of two adjacent edges of the sheet 300.

[0075] The positioning module 10 is disposed on a side of the first workbench 1 opposite to the first limiting plate 401. The positioning module 10 includes a second limiting plate 101 and a first driving member 102, wherein the second limiting plate 101 is connected to a driving end of the first driving member 102, and the first driving member 102 drives the second limiting plate 101 to move closer to or away from the first workbench 1 in the Y direction.

[0076] When the sheet 300 is placed on the first workbench 1, the first limiting plate 401 and the third limiting plate 402 will limit the position of the sheet 300 at the first limiting plate 401 and the third limiting plate 402, and the first driving member 102 drives the second limiting plate 101 to approach the direction of the first workbench 1 in the Y direction, and the positions of the two opposite edges of the sheet 300 are limited by the first limiting plate 401 and the second limiting plate 101, thereby realizing the positioning of the sheet 300, so when the sheet 300 is bent, the bending size of the packaging box 200 can be guaranteed.

[0077] In this embodiment, the first bending module 3 includes a third driving mechanism 31 and a first bending portion 32. The third driving mechanism 31 is arranged along the first direction, and the first bending portion 32 is arranged at the driving end of the third driving mechanism 31. The third driving mechanism 31 drives the first bending portion 32 to move along the first direction, and the first bending portion 32 performs the first bending on the sheet material 300.

[0078] like Figure 3 As shown, the first bending module 3 includes a third driving mechanism 31 and a first bending portion 32 , and the first bending portion 32 is disposed at a driving end of the third driving mechanism 31 .

[0079] The third driving mechanism 31 is disposed along the first direction, so the third driving mechanism 31 can drive the first bending portion 32 to move along the first direction.

[0080] To further illustrate, the sheet material 300 is placed on the first workbench 1, and the third connecting part 208, the fourth connecting part 209 and the fifth connecting part 210 cover the avoidance hole 12, and the third driving mechanism 31 drives the first bending part 32 to move along the first direction, so that the third connecting part 208, the fourth connecting part 209 and the fifth connecting part 210 are bent in the first direction, thereby forming a first crease 201 between the second connecting part 207 and the third connecting part 208, completing the first bending.

[0081] In one embodiment, the first direction is the Z direction.

[0082] In one embodiment, the plane where the first direction is located has an angle with the plane where the X direction is located, the first bending portion 32 includes a first pressing roller 321 and a second pressing roller 322, the driving end of the third driving mechanism 31 includes a first mounting portion 311 and a second mounting portion 312, the first mounting portion 311 is closer to the avoidance hole 12 than the second mounting portion 312, the first pressing roller 321 is arranged on the first mounting portion 311, and the second pressing roller 322 is arranged on the second mounting portion 312.

[0083] like Figure 3 As shown, the driving end of the third driving mechanism 31 includes a first mounting portion 311 and a second mounting portion 312. Since the third driving mechanism 31 is arranged along the first direction, the two sides of the driving end of the third driving mechanism 31 are not flush, and the first mounting portion 311 is closer to the avoidance hole 12 than the second mounting portion 312.

[0084] The first bending portion 32 includes a first pressing roller 321 and a second pressing roller 322 . The first pressing roller 321 is disposed on the first mounting portion 311 , and the second pressing roller 322 is disposed on the second mounting portion 312 .

[0085] When the third driving mechanism 31 drives the first pressing roller 321 and the second pressing roller 322 to approach the sheet material 300 in the first direction, the first pressing roller 321 first contacts the sheet material 300 to form a certain angle, and then the second pressing roller 322 contacts the sheet material 300. This can prevent the first pressing roller 321 from directly bending the sheet material 300 and damaging the sheet material 300.

[0086] In this embodiment, the second bending module 4 includes a fourth driving mechanism 41 and a second top bending portion 42. The driving end of the fourth driving mechanism 41 is connected to the second top bending portion 42. The fourth driving mechanism 41 drives the second top bending portion 42 to move along the Z direction, and the second top bending portion 42 bends the sheet material 300 for the second time.

[0087] like Figure 4 As shown, the second bending module 4 includes a fourth driving mechanism 41 and a second top bending portion 42 .

[0088] The second top bending portion 42 is disposed at a driving end of the fourth driving mechanism 41 , and the fourth driving mechanism 41 drives the second top bending portion 42 to move closer to or away from the first workbench 1 in the Z direction.

[0089] Further explanation, the second bending module 4 is arranged on the side of the first workbench 1. After the sheet 300 is placed on the first workbench 1, the first connection portion 206 is exposed on the first workbench 1. The second bending module 4 is arranged on the side of the first workbench 1, and the second top bending portion 42 is driven by the fourth driving mechanism 41 to move toward the direction close to the first workbench 1. The second top bending portion 42 will contact the sheet 300 to bend the first connection portion 206 upward in the Z direction, thereby forming a second fold 202 between the first connection portion 206 and the second connection portion 207.

[0090] In this embodiment, the second bending module 4 also includes a fifth driving mechanism 43 and a second side bending portion 44. The fifth driving mechanism 43 drives the second side bending portion 44 to approach or move away from the first workbench 1 along the X direction. The second top bending portion 42 is provided with a first avoidance portion 421. The fifth driving mechanism 43 can drive the second side bending portion 42 to approach the first workbench 1 and pass through the first avoidance portion 421 to perform a second bend on the sheet 300.

[0091] like Figure 4 As shown, the second bending module 4 further includes a fifth driving mechanism 43 and a second side bending portion 44. The second side bending portion 44 is disposed at the driving end of the fifth driving mechanism 43, and the fifth driving mechanism 43 drives the second side bending portion 44 to approach or move away from the first workbench 1 in the X direction.

[0092] Further explanation, the second top bending portion 42 is provided with a first avoidance portion 421, and the first avoidance portion 421 corresponds to the position of the second side bending portion 44, that is, the fifth driving mechanism 43 can drive the second side bending portion 44 to approach the first workbench 1 through the first avoidance portion 421. The fifth driving mechanism 43 drives the second side bending portion 44 to approach the first workbench 1, so as to further bend the second fold 202 of the sheet 300, so that the second fold 202 is clearer.

[0093] Preferably, the second bending module 4 further includes a connecting plate. The fifth driving mechanism 43 and the second side bending portion 44 are arranged on the connecting plate, the second top bending portion 42 is arranged on the connecting plate, the connecting plate is connected to the driving end of the fourth driving mechanism 41, and the fourth driving mechanism 41 drives the connecting plate to move in the Z direction, and at the same time drives the second top bending portion 42, the second side bending portion 44 and the fifth driving mechanism 43 to move.

[0094] To further illustrate, the second side bending portion 44 and the third limiting plate 402 are located on two opposite sides of the first workbench 1 , and the second side bending portion 44 and the third limiting plate 402 can work together to limit the positions of two opposite edges of the sheet material 300 .

[0095] In this embodiment, the third bending module 5 is arranged in the conveying module 2, and the third bending module 5 includes a sixth driving mechanism 51, a third bending part 52 and a fourth bending part 53. The driving end of the sixth driving mechanism 51 is connected to the third bending part 52, and the sixth driving mechanism 51 drives the third bending part 52 to move along the Z direction; the fourth bending part 53 is arranged below the third bending part 52, and the sheet material 300 after the first bending can be close to the fourth bending part 53, and the sixth driving mechanism 51 drives the third bending part 52 to move toward the direction of the fourth bending part 53 to bend the sheet material 300 for the third time.

[0096] like Figure 5 As shown, the third bending module 5 is arranged on the transport module 2. Specifically, the third bending module 5 is arranged at the driving end of the transfer mechanism, and in the Z direction, the third bending module 5 is located above the suction plate 22. When the transfer mechanism drives the suction plate 22 to approach the first workbench 1, the third bending module 5 will also approach the first workbench 1.

[0097] like Figure 5 As shown, the third bending module 5 includes a sixth driving mechanism 51, a third bending portion 52 and a fourth bending portion 53. The third bending portion 52 is connected to the driving end of the sixth driving mechanism 51, and the fourth driving mechanism 41 can drive the third bending portion 52 to move closer to or away from the first workbench 1 in the Z direction. The fourth bending portion 53 is arranged between the third bending portion 52 and the adsorption plate 22.

[0098] It is further explained that the third bending module 5 is performed after the first bending module 3 performs the first bending on the sheet 300. Therefore, the first bending module 3 performs the first bending on the sheet 300, so that the third connection part 208, the fourth connection part 209 and the fifth connection part 210 will bend in the direction close to the third bending module 5. Under the action of the first bending module 3, the third connection part 208, the fourth connection part 209 and the fifth connection part 210 will form an acute angle with the second connection part 207, so that the fifth connection part 210 located at the edge of the sheet 300 will be close to the fourth bending part 53, and the fifth connection part 210 will expose the fourth bending part 53. The third bending part 52 is driven by the sixth driving mechanism 51 to approach the direction of the fourth bending part 53, and the third bending is completed through the third bending part 52 and the fourth bending part 53, so as to form a third fold 203 between the fourth connection part 209 and the fifth connection part 210.

[0099] Preferably, the third bending module 5 also includes a tenth driving mechanism, and the fourth bending portion 53 is connected to the driving end of the tenth driving mechanism. The tenth driving mechanism can drive the fourth bending portion 53 to move along the Z direction, and can adjust the position of the fourth bending portion 53 according to the size of the sheet 300 to adapt to sheets 300 of different sizes.

[0100] In a preferred embodiment, the fourth bending portion 53 is provided with a second avoidance portion 531, and a pushing mechanism 54 and a push block are provided on the first driving mechanism 21. The push block is provided at the driving end of the pushing mechanism 54, and the pushing mechanism 54 can drive the push block to approach or move away from the second avoidance portion 531 in the X direction. After the third bending, the sheet 300 will be transferred to the second workbench 8. However, after the third bending, a third fold 203 is formed between the fifth connecting portion 210 and the fourth connecting portion 209. Due to the third fold 203, the fifth connecting portion 210 and the fourth connecting portion 209 are respectively located on both sides of the fourth bending portion 53. Therefore, when the sheet 300 is transferred to the second workbench 8, it will be affected by the fourth bending portion 53. By setting up a pushing mechanism 54 and a pushing block, the pushing mechanism 54 drives the pushing block to approach the fourth bending portion 53, and the pushing block will pass through the second avoidance portion 531 to push the fourth connecting portion 209 attached to the fourth bending portion 53 in the direction away from the fourth bending portion 53, so that the fifth connecting portion 210 is away from the fourth bending portion 53, so as to facilitate its delivery to the second workbench 8.

[0101] In this embodiment, the fourth bending module 6 includes a pressing block mechanism 61, and the pressing block mechanism 61 is arranged on the second workbench 8; the pressing block mechanism 61 includes a second driving member 611 and a pressing block 612, the driving end of the second driving member 611 is connected to the pressing block 612, and the second driving member 611 drives the pressing block 612 to approach or move away from the second workbench 8 along the Y direction.

[0102] like Figure 2 and Figure 6 As shown, the fourth bending module 6 includes a block pressing mechanism 61. The block pressing mechanism 61 is arranged on one side of the second workbench 8. The block pressing mechanism 61 can press the sheet material 300 placed on the second workbench 8 to facilitate the fourth bending of the sheet material 300 and prevent the sheet material 300 from deflecting.

[0103] Further explanation: the fourth bending module 6 is provided with two pressing block mechanisms 61, which are respectively located on both sides of the second workbench 8. The two pressing block mechanisms 61 are used to press the two ends of the sheet material 300, and the sheet material 300 is further prevented from being offset when the fourth bending is performed.

[0104] like Figure 2As shown, the pressing block mechanism 61 includes a second driving member 611 and a pressing block 612. The pressing block 612 is arranged at the driving end of the second driving member 611. The second driving member 611 can drive the pressing block 612 to approach or move away from the second workbench 8 in the Y direction. When the sheet material 300 is placed on the second workbench 8 and needs to be bent for the fourth time, the second driving member 611 drives the pressing block 612 to approach the second workbench 8, so that the pressing block 612 presses the sheet material 300 on the second workbench 8, so as to facilitate the fourth bending of the sheet material 300.

[0105] In a preferred embodiment, in the Z direction, the distance between the surface of the pressing block 612 away from the second workbench 8 and the surface of the second workbench 8 close to the pressing block 612 is the same as the vertical distance between the first fold 201 and the fourth fold 204. When the sheet material 300 is bent for the fourth time, the third connecting portion 208 can be just attached to the side of the pressing block 612 to play a role in dimensional positioning of the sheet material 300.

[0106] Further description, the pressing mechanism 61 also includes a third driving member, the second driving member 611 is connected to the driving end of the third driving member, and the third driving member can drive the second driving member 611 to move in the Z direction to adjust the distance between the surface of the pressing block 612 away from the second workbench 8 and the surface of the second workbench 8 close to the pressing block 612, so as to adapt to packaging boxes 200 of different sizes.

[0107] In this embodiment, the fourth bending module 6 also includes a seventh driving mechanism 62, an eighth driving mechanism 63 and a pressing plate 64. The driving end of the seventh driving mechanism 62 is connected to the eighth driving mechanism 63. The seventh driving mechanism 62 drives the eighth driving mechanism 63 to move along the X direction. The driving end of the eighth driving mechanism 63 is connected to the pressing plate 64. The eighth driving mechanism 63 drives the pressing plate 64 along the Z direction to bend the sheet material 300 for the fourth time.

[0108] like Figure 6 As shown, the fourth bending module 6 further includes a seventh driving mechanism 62, an eighth driving mechanism 63 and a pressing plate 64. The seventh driving mechanism 62, the eighth driving mechanism 63 and the pressing plate 64 are arranged on one side of the second workbench 8 adjacent to the block pressing mechanism 61.

[0109] Among them, the pressing plate 64 is connected to the driving of the eighth driving mechanism 63, and the eighth driving mechanism 63 can drive the pressing plate 64 to approach or move away from the second workbench 8 in the Z direction; the eighth driving mechanism 63 is connected to the driving end of the seventh driving mechanism 62, and the seventh driving mechanism 62 can drive the eighth driving mechanism 63 to approach or move away from the second workbench 8 in the X direction.

[0110] Further explanation: the sheet material 300 that has completed the first, second and third bendings on the first workbench 1 is transferred to the second workbench 8 for the fourth bending. The second connection part 207 is pressed on the second workbench 8, the third connection part 208, the fourth connection part 209 and the fifth connection part 210 are located on the side of the second workbench 8 close to the pressing plate 64, and the seventh driving mechanism 62 and the eighth driving mechanism 63 drive the pressing plate 64 to approach the second workbench 8 in the X direction and the Z direction, so as to bend the fourth connection part 209 in the direction close to the second connection part 207, complete the fourth bending, and form the fourth fold 204 between the third connection part 208 and the fourth connection part 209.

[0111] In this embodiment, the sealing module 7 includes a ninth driving mechanism 71 and a sealing mechanism 72 . The driving end of the ninth driving mechanism 71 is connected to the sealing mechanism 72 . The ninth driving mechanism 71 drives the sealing mechanism 72 to move along the X direction.

[0112] like Figure 6 As shown, the sealing module 7 is arranged on a side of the second workbench 8 opposite to the seventh driving mechanism 62 , the eighth driving mechanism 63 and the pressing plate 64 .

[0113] The sealing module 7 includes a ninth driving mechanism 71 and a sealing mechanism 72. The sealing mechanism 72 is connected to the driving end of the ninth driving mechanism 71, and the ninth driving mechanism 71 can drive the sealing mechanism 72 to move closer to or away from the second workbench 8 in the X direction.

[0114] Further explanation: the sheet 300 that has completed the first bending, the second bending, and the third bending on the first workbench 1 is transferred to the second workbench 8 for the fourth bending. Among them, the second connection part 207 is pressed on the second workbench 8, and the first connection part 206 is located on the side of the second workbench 8 close to the sealing module 7. After the fourth bending is completed, the fifth connection part 210 is attached to the first connection part 206, and the fourth connection part 209 is perpendicular to the first connection part 206. The sealing area 212 located at the fourth connection part 209 corresponds to the position of the sealing part 211. The ninth driving mechanism 71 drives the sealing mechanism 72 to approach the second workbench 8 in the X direction, and can bend the sealing part 211 in the direction close to the sealing part 211, so that the sealing part 211 is pressed against the sealing area 212 to complete the sealing.

[0115] In this embodiment, the pressing plate 64 is provided with an avoidance groove 641 , and the sealing mechanism 72 corresponds to the position of the avoidance groove 641 .

[0116] like Figure 6As shown, an avoidance groove 641 is provided on the pressure plate 64. When the fourth fold 204 is bent by the pressure plate 64, the pressure plate 64 will be pressed on the fourth connecting portion 209, and the sealing area 212 located at the fourth connecting portion 209 will be exposed through the avoidance groove 641, so that the sealing mechanism 72 can press the sealing portion 211 tightly against the sealing area 212.
