Description

Technical Field

[0001] This application relates to the field of liquefied gas storage tank technology, and more particularly to a pressing device and a production line for corrugated plates. Background Technology

[0002] The primary and secondary shielding membranes of the membrane-type liquefied gas storage tank are made of corrugated plates. The corrugated structure on the plates is used to absorb the deformation of the primary and secondary shielding membranes caused by thermal stress.

[0003] In related technologies, corrugated sheets contain multiple corrugations. The pressing equipment for corrugated sheets uses only one pressing mold. When pressing multiple corrugations, the placement of the corrugated sheet on the pressing equipment needs to be changed multiple times. This results in poor positioning accuracy of the corrugations on the sheet and low production efficiency. Summary of the Invention

[0004] This application provides a pressing device and a production line for corrugated sheets, which improves the positioning accuracy of corrugations on the corrugated sheets and increases the production efficiency of corrugated sheets.

[0005] In a first aspect, this application provides a pressing device for pressing corrugations on a corrugated sheet. The pressing device includes: a clamping device, a pressing die device, a first driving device, and a second driving device. The clamping device clamps both ends of the corrugated sheet along a first direction, where the first direction is the length direction of the corrugated sheet. The pressing die device includes a first roller, a second roller, an upper die, and a lower die. The first roller is positioned above the corrugated sheet along a second direction, where the second direction is the thickness direction of the corrugated sheet. The second roller is positioned below the corrugated sheet along the second direction. A first slot is provided on the first roller, opening along the axial direction of the first roller. A second slot is provided on the second roller, opening along the axial direction of the second roller. The upper die is detachably connected to the first slot, and the lower die is detachably connected to the second slot. The upper and lower dies are positioned correspondingly for pressing corrugations. The first driving device drives the first and second rollers to roll along the first direction. The second driving device drives the first and second rollers to move along the second direction, causing the upper and lower dies to act simultaneously on the corrugated sheet.

[0006] The pressing device provided in the first aspect of this application is used to press corrugations on a corrugated plate. The pressing device includes a clamping device, a pressing die device, a first driving device, and a second driving device. The clamping device is used to fix the position of the corrugated plate, ensuring that the corrugated plate remains in a fixed position during the pressing process. The pressing die device includes a first roller, a second roller, an upper die, and a lower die. The first roller is positioned above the corrugated plate along a second direction, and the second roller is positioned below the corrugated plate along the second direction, thus placing the corrugated plate between the first roller and the second roller. A first slot on the first roller is used to connect to the upper die. A second slot on the second roller is used to connect to the lower die. The upper and lower dies are positioned correspondingly so that when the second driving device drives the first and second rollers, the upper and lower dies can complete the pressing of one corrugation. The first driving device drives the first and second rollers to roll along a first direction, causing the upper and lower dies to move along the first direction and perform multiple pressings on the corrugated plate, thereby pressing multiple corrugations on the corrugated plate in the first direction. In other words, if the corrugated sheet can maintain its position during the corrugation pressing process, multiple corrugations can be pressed onto the corrugated sheet using the pressing equipment provided in this application, thereby improving the positioning accuracy of the corrugations on the corrugated sheet and increasing the production efficiency of the corrugated sheet.

[0007] In one possible design, the first driving device includes a first actuating component, a second actuating component, and two motors. The first actuating component is connected to a first roller, and the second actuating component is connected to a second roller. The first actuating component includes a first connecting member and a first guide rail, and is positioned above the corrugated plate along a second direction. The second actuating component includes a second connecting member and a second guide rail, and is positioned below the corrugated plate along a second direction. The first connecting member is connected to one end of the first roller along its length. The second connecting member is connected to one end of the second roller along its length. The first connecting member is connected to the side of the first guide rail facing the corrugated plate and rolls along the length of the first guide rail. The second connecting member is connected to the side of the second guide rail facing the corrugated plate and rolls along the length of the second guide rail. The length directions of both the first and second guide rails are a first direction, and the lengths of both the first and second guide rails are greater than or equal to the length of the corrugated plate. The two motors are respectively connected to the first and second connecting members to drive the first and second connecting members to roll.

[0008] Based on the description of the above embodiments, the first driving device includes a first actuating component, a second actuating component, and two motors. The first actuating component is connected to a first roller, and one motor drives the first actuating component to make the first roller roll along a first direction. The second actuating component is connected to a second roller, and the other motor drives the second actuating component to make the second roller roll along the first direction. A first connecting member is connected to one end of the first roller along its length, driving the first roller to roll along the first direction so that the upper mold can perform multiple pressing along the first direction. A second connecting member is connected to one end of the second roller along its length, driving the second roller to roll along the first direction so that the lower mold can perform multiple pressing along the first direction. Further, the first connecting member is connected to the side of the first guide rail facing the corrugated plate, and the second connecting member is connected to the side of the second guide rail facing the corrugated plate, so that the upper and lower molds can smoothly perform multiple pressings along the first direction, thereby enabling the pressing equipment to smoothly complete the pressing of multiple corrugations on the corrugated plate.

[0009] In one possible design, gears are provided on the outer surfaces of both the first and second connecting members. A rack extending in a first direction is provided on the side of the first guide rail facing the corrugated plate. A rack extending in the first direction is also provided on the side of the second guide rail facing the corrugated plate. The gear on the first connecting member meshes with the rack in the first guide rail, causing the first connecting member to roll in the first direction. The gear on the second connecting member meshes with the rack in the second guide rail, causing the second connecting member to roll in the first direction.

[0010] Based on the description of the above embodiments, the gear on the outer surface of the first connector / second connector meshes with the rack on the first guide rail / second guide rail. The gear rolls along the extension direction of the rack, thereby driving the first roller / second roller to roll along the first direction. The gear-rack meshing connection structure has high precision and good stability during rolling, which can further improve the positioning accuracy of the corrugations on the corrugated plate.

[0011] In one possible design, a first roller has multiple first slots evenly distributed across its surface. A second roller has multiple second slots evenly distributed across its surface. The number of first and second slots is the same. The multiple first slots are used to connect to multiple upper molds, the number of which is less than or equal to the number of first slots. The multiple second slots are used to connect to multiple lower molds, the number of which is less than or equal to the number of second slots. The number of upper and lower molds is the same.

[0012] Based on the description of the above embodiments, a plurality of first slots evenly distributed on the surface of the first roller are used to connect a plurality of upper dies. A plurality of second slots evenly distributed on the surface of the second roller are used to connect a plurality of lower dies. The number of first slots and second slots is the same, and the number of upper dies and lower dies is the same. The number of upper dies is less than or equal to the number of first slots, and the number of lower dies is less than or equal to the number of second slots. Therefore, by adjusting the distribution of the plurality of upper dies / lower dies on the first roller / second roller, and by adjusting the number of upper dies / lower dies, the distance between the corrugations pressed in two consecutive presses can be adjusted, thereby improving the versatility of the pressing equipment and enabling the pressing equipment to press corrugated sheets of various specifications, thereby reducing the production cost of corrugated sheets.

[0013] In one possible design, the portion of the upper die that contacts the corrugated plate is a raised structure. The portion of the lower die that contacts the corrugated plate is a recessed structure. One upper die and one lower die constitute a pressing unit. Multiple raised structures have different dimensions, and multiple recessed structures have different dimensions. The dimensions of the raised structures and the dimensions of the recessed structures in a pressing unit correspond to each other.

[0014] Based on the description of the above embodiments, the portion of the upper mold that contacts the corrugated plate is a raised structure, and the portion of the lower mold that contacts the corrugated plate is a recessed structure. The raised structure presses the corrugated plate into the recessed structure, thus pressing a corrugation onto the corrugated plate. An upper mold and a lower mold constitute a pressing unit, and the dimensions of the raised structure and the recessed structure in a pressing unit correspond to each other, allowing the upper mold to smoothly press the corrugated plate into the lower mold, thereby completing the corrugation pressing. Furthermore, multiple raised structures have different dimensions, and multiple recessed structures have different dimensions, allowing the pressing device to include multiple pressing units of different sizes for pressing corrugations of different sizes. This further improves the versatility of the pressing equipment, enabling it to press corrugated plates of various specifications, thereby reducing the production cost of corrugated plates.

[0015] In one possible design, the pressing device may also include a limiting device. The limiting device includes two sets of abutment components, one set for limiting the position of the first roller and the other set for limiting the position of the second roller. The abutment components are positioned on the rolling path of the first or second roller to limit its rolling in a first direction. The number of limiting devices is equal to the number of corrugations.

[0016] Based on the description of the above embodiments, the two sets of abutment components in the limiting device are respectively disposed on the rolling paths of the first roller and the second roller, used to limit the positions of the first roller and the second roller, thereby improving the positioning accuracy of the upper mold and the lower mold, and further improving the positioning accuracy of the corrugations on the corrugated plate. Furthermore, the number of limiting devices is equal to the number of corrugations, so that the positions of the limiting devices correspond one-to-one with the positions of the corrugations, thereby improving the positioning accuracy of all corrugations on the corrugated plate.

[0017] In one possible design, the abutment assembly includes two snap-fit ​​blocks for abutting against either a first roller or a second roller. A first guide rail has multiple snap-fit ​​grooves distributed along a first direction on its surface facing the first roller. A second guide rail has multiple snap-fit ​​grooves distributed along the first direction on its surface facing the second roller. The snap-fit ​​blocks are slidably connected within the snap-fit ​​grooves. Each snap-fit ​​block includes a first end and a second end positioned along a second direction. The first end protrudes along the second direction from the top of the first roller or the bottom of the second roller. A gap exists between the second end and the groove wall of the snap-fit ​​groove, and an elastic element connects the second end and the snap-fit ​​groove. The distance between the two snap-fit ​​blocks is substantially equal to the dimension of the first roller and the second roller in the first direction.

[0018] Based on the description of the above embodiments, the abutment assembly includes two locking blocks. A first guide rail has multiple locking grooves distributed along a first direction on its surface facing the first roller, and a second guide rail has multiple locking grooves distributed along the first direction on its surface facing the second roller. Both are used to connect the locking blocks, allowing the locking blocks to abut against the first roller or the second roller in the first direction, thereby limiting the movement of the first and second rollers. Further, a first end of the locking block protrudes along a second direction from the top of the first roller or the bottom of the second roller, allowing the locking block to abut against the first and second rollers. A gap exists between the second end of the locking block and the wall of the locking groove, and an elastic element connects the second end to the locking groove. This allows the first roller or the second roller to reset via the elastic element after passing over the locking block, enabling the first roller or the second roller to flexibly engage between any two locking blocks, thereby achieving flexible positioning of the molding device. Furthermore, the distance between the two locking blocks is approximately equal to the dimensions of the first roller and the second roller in the first direction, which can fix the first roller or the second roller between the two locking blocks, thereby limiting the position of the first roller and the second roller, improving the positioning accuracy of the upper mold and the lower mold, and further improving the positioning accuracy of the corrugations on the corrugated plate.

[0019] In one possible design, the second drive unit includes a third actuating assembly and a fourth actuating assembly. The third actuating assembly includes a third connecting member, a telescopic rod, and a hydraulic cylinder. The fourth actuating assembly includes a fourth connecting member, a telescopic rod, and a hydraulic cylinder. The third connecting member is sleeved on a first roller, and the fourth connecting member is sleeved on a second roller. The telescopic rod is connected to either the third or fourth connecting member. The hydraulic cylinder is used to drive the telescopic rod to extend or retract in a second direction.

[0020] Based on the description of the above embodiments, the second driving device includes a third actuation component and a fourth actuation component. The third actuation component includes a third connector, a telescopic rod, and a hydraulic cylinder. The third connector is sleeved on the first roller, enabling the first roller to roll while connected to the third connector. The fourth actuation component includes a fourth connector, a telescopic rod, and a hydraulic cylinder. The fourth connector is sleeved on the second roller, enabling the second roller to roll while connected to the fourth connector. The hydraulic cylinder drives the telescopic rod to extend and retract along a second direction. The telescopic rod is connected to the third / fourth connector, causing the third / fourth connector to move along the second direction, thereby moving the upper / lower mold towards the corrugated plate, thus completing one pressing action.

[0021] In one possible design, the clamping device includes two pressure plates parallel to the corrugated plate. The corrugated plate is positioned between the two pressure plates. The side of the pressure plates facing the corrugated plate has an anti-slip structure. Fastening bolts connect the two pressure plates, pressing them firmly against the corrugated plate.

[0022] Based on the description of the above embodiments, the clamping device places the corrugated plate between two pressure plates. The tightness of the clamping device in holding the corrugated plate is adjusted by turning the fastening bolts connecting the two pressure plates, so as to select a suitable tightness and keep the corrugated plate stationary during the pressing process.

[0023] Secondly, this application provides a production line for corrugated sheets, including the pressing equipment described in any of the above embodiments.

[0024] The corrugated sheet production line provided in the second aspect above has the same beneficial effects as the first aspect and the various possible implementations of the first aspect, and will not be repeated here. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0046] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0047] The primary and secondary shielding membranes of the membrane-type liquefied gas storage tank are made of corrugated plates. The corrugated structure on the plates is used to absorb the deformation of the primary and secondary shielding membranes caused by thermal stress.

[0048] In related technologies, corrugated sheets contain multiple corrugations. The pressing equipment for corrugated sheets uses only one pressing mold. When pressing multiple corrugations, the placement of the corrugated sheet on the pressing equipment needs to be changed multiple times. This results in poor positioning accuracy of the corrugations on the sheet and low production efficiency.

[0049] Based on this, this application provides a pressing device and a production line for corrugated sheets. By setting the upper and lower molds in the pressing device on the first and second rollers, the pressing device can move along the distribution direction of the corrugations, keeping the position of the corrugated sheet constant. This eliminates the need for multiple movements of the corrugated sheet, thereby improving the positioning accuracy of the corrugations on the corrugated sheet and increasing the production efficiency of the corrugated sheet. The following is in conjunction with... Figures 1-9Please provide a detailed explanation.

[0050] In a first aspect, this application provides a pressing device 100 for pressing corrugations on a corrugated plate 200. The pressing device 100 includes: a clamping device 1, a pressing mold device 2, a first driving device 3, and a second driving device 4. The clamping device 1 clamps both ends of the corrugated plate 200 along a first direction X, where the first direction X is the length direction of the corrugated plate 200. The pressing mold device 2 includes a first roller 21, a second roller 22, an upper mold 23, and a lower mold 24. The first roller 21 is disposed above the corrugated plate 200 along a second direction Y, where the second direction Y is the thickness direction of the corrugated plate 200. The second roller 22 is disposed below the corrugated plate 200 along the second direction Y. A first slot 211 is provided on the first roller 21, and the first slot 211 is opened along the axial direction of the first roller 21. A second slot 221 is provided on the second roller 22, and the second slot 221 is opened along the axial direction of the second roller 22. The upper mold 23 is detachably connected to the first slot 211, and the lower mold 24 is detachably connected to the second slot 221. The upper mold 23 and the lower mold 24 are positioned correspondingly and are used to press corrugations. The first driving device 3 drives the first roller 21 and the second roller 22 to roll along the first direction X. The second driving device 4 drives the first roller 21 and the second roller 22 to move along the second direction Y, so that the upper mold 23 and the lower mold 24 act simultaneously on the corrugated plate 200.

[0051] Among them, such as Figure 1 As shown, the clamping device 1 clamps the corrugated plate 200 at both ends along the first direction X, used to fix the position of the corrugated plate 200. This ensures that the corrugated plate 200 maintains its position during the corrugation process. Here, the first direction X is the length direction of the corrugated plate 200. Simultaneously, as... Figure 1 As shown, the first direction X is also the direction in which the corrugations are distributed on the corrugated plate 200.

[0052] The molding device 2 includes a first roller 21, a second roller 22, an upper mold 23, and a lower mold 24.

[0053] Specifically, the first roller 21 is positioned above the corrugated plate 200 along the second direction Y. Here, the second direction Y is the thickness direction of the corrugated plate 200. Figure 1 As shown, the second direction Y is perpendicular to the first direction X.

[0054] The second roller 22 is positioned below the corrugated plate 200 along the second direction Y, thereby positioning the corrugated plate 200 between the first roller 21 and the second roller 22.

[0055] Furthermore, the lengths of the first roller 21 and the second roller 22 can be greater than or equal to the width of the corrugated plate 200, so that the molding device 2 can completely cover the corrugated plate 200 in the width direction, thereby enabling the molding device 2 to press out corrugations that extend through the width of the corrugated plate 200.

[0056] Furthermore, such as Figure 2 As shown, a first slot 211 is provided on the first roller 21, and the first slot 211 is used to connect the upper mold 23. The first slot 211 is opened along the axial direction of the first roller 21.

[0057] like Figure 2 As shown, a second slot 221 is provided on the second roller 22, and the second slot 221 is used to connect the lower mold 24. The second slot 221 is opened along the axial direction of the second roller 22.

[0058] Furthermore, such as Figure 3 As shown, the upper mold 23 and the lower mold 24 are positioned correspondingly to press the corrugations on the corrugated plate 200. Specifically, when the upper mold 23 is located at the top of the corrugated plate 200 and the lower mold 24 is located at the bottom of the corrugated plate 200, the positions of the upper mold 23 and the lower mold 24 are aligned. For example, as shown... Figure 1 As shown, the second driving device 4 drives the first roller 21 and the second roller 22 to move along the second direction Y until the upper mold 23 and the lower mold 24 complete the corrugation pressing action. The corrugation pressing action includes: the upper mold 23 and the lower mold 24 acting simultaneously on the corrugated plate 200, and the upper mold 23 pressing the corrugated plate 200 into the lower mold 24, thereby forming a corrugation on the corrugated plate 200.

[0059] Furthermore, such as Figure 1 As shown, the first driving device 3 drives the first roller 21 and the second roller 22 to roll along the first direction X, for pressing multiple corrugations distributed along the first direction X. Specifically, the rolling of the first roller 21 along the first direction X causes the upper mold 23 to rotate multiple times above the corrugated plate 200. Similarly, the rolling of the second roller 22 along the first direction X causes the lower mold 24 to rotate multiple times below the corrugated plate 200, thereby allowing multiple pressing operations on the corrugated plate 200. Furthermore, since the first roller 21 and the second roller 22 roll along the first direction X, the positions of the upper mold 23 and the lower mold 24 on the corrugated plate 200 for multiple pressing operations will move along the first direction X, thereby enabling multiple pressing operations to press multiple corrugations on the corrugated plate 200 in the first direction X.

[0060] Furthermore, the upper mold 23 is detachably connected to the first slot 211, allowing for flexible replacement and maintenance. Similarly, the lower mold 24 is detachably connected to the second slot 221, allowing for flexible replacement and maintenance, thus reducing the maintenance cost of the pressing equipment 100 and consequently reducing the production cost of the pressed corrugated plate 200.

[0061] The detachable connection can be a snap-fit ​​or a threaded connection, etc., and this application does not limit it.

[0062] In summary, the pressing device 100 provided in the first aspect of this application is used to press corrugations on a corrugated plate 200. The pressing device 100 includes a clamping device 1, a pressing die device 2, a first driving device 3, and a second driving device 4. The clamping device 1 is used to fix the position of the corrugated plate 200, ensuring that the corrugated plate 200 remains in a fixed position during the pressing process. The pressing die device 2 includes a first roller 21, a second roller 22, an upper die 23, and a lower die 24. The first roller 21 is positioned above the corrugated plate 200 along a second direction Y, and the second roller 22 is positioned below the corrugated plate 200 along the second direction Y, thereby positioning the corrugated plate 200 between the first roller 21 and the second roller 22. A first slot 211 provided on the first roller 21 is used to connect to the upper die 23. A second slot 221 provided on the second roller 22 is used to connect to the lower die 24. The upper mold 23 and the lower mold 24 are positioned correspondingly so that when the second driving device 4 drives the first roller 21 and the second roller 22, the upper mold 23 and the lower mold 24 can complete the pressing of one corrugation. The first driving device 3 drives the first roller 21 and the second roller 22 to roll along the first direction X, so that the pressing position of the upper mold 23 and the lower mold 24 on the corrugated plate 200 moves along the first direction X and performs multiple pressings, thereby pressing multiple corrugations on the corrugated plate 200 in the first direction X. In other words, if the corrugated plate 200 can maintain a constant position during the corrugation pressing process, multiple corrugations can be pressed on the corrugated plate 200 by the pressing equipment 100 provided in this application, thereby improving the positioning accuracy of the corrugations on the corrugated plate 200 and improving the production efficiency of the corrugated plate 200.

[0063] Next, this application will provide a detailed description of the first driving device 3, the second driving device 4, and the clamping device 1 through the following embodiments.

[0064] In some embodiments, the first driving device 3 includes a first actuation component 31, a second actuation component 32, and two motors. The first actuation component 31 is connected to a first roller 21, and the second actuation component 32 is connected to a second roller 22. The first actuation component 31 includes a first connector 311 and a first guide rail 312, and is positioned above the corrugated plate 200 along a second direction Y. The second actuation component 32 includes a second connector 321 and a second guide rail 322, and is positioned below the corrugated plate 200 along a second direction Y. The first connector 311 is connected to one end of the first roller 21 along its length. The second connector 321 is connected to one end of the second roller 22 along its length. The first connector 311 is connected to the side of the first guide rail 312 facing the corrugated plate 200, and rolls along the length of the first guide rail 312. The second connector 321 is connected to the side of the second guide rail 322 facing the corrugated plate 200, and rolls along the length of the second guide rail 322. The length directions of the first guide rail 312 and the second guide rail 322 are both in the first direction X, and the lengths of the first guide rail 312 and the second guide rail 322 are both greater than or equal to the length of the corrugated plate 200. Two motors are respectively connected to the first connector 311 and the second connector 321 to drive the first connector 311 and the second connector 321 to roll.

[0065] like Figure 1 As shown, the first driving device 3 includes a first actuation component 31, a second actuation component 32, and two motors. The first actuation component 31 is connected to the first roller 21, and one motor drives the first actuation component 31 to make the first roller 21 roll along a first direction X. The second actuation component 32 is connected to the second roller 22, and the other motor drives the second actuation component 32 to make the second roller 22 roll along the first direction X.

[0066] The first actuation component 31 includes a first connector 311 and a first guide rail 312. Specifically, as shown... Figure 1 As shown, the first actuating component 31 is positioned above the corrugated plate 200 along the second direction Y, so that the first connector 311 can be connected to the first roller 21.

[0067] Furthermore, such as Figure 4As shown, the length direction of the first guide rail 312 is the first direction X, and the first guide rail 312 is laid on one side of the first roller 21 along the length direction of the first roller 21. The first connecting member 311 is connected to one end of the first roller 21 along the length direction of the first roller 21, so that the first connecting member 311 can be connected to the first guide rail 312 and can roll along the length direction of the first guide rail 312, thereby driving the first roller 21 to roll along the first direction X, so that the upper mold 23 can perform multiple pressing along the first direction X. For example, the first action component 31 may include two first connecting members 311, so that the two first connecting members 311 are respectively connected to the two ends of the first roller 21 along the length direction of the first roller 21.

[0068] Furthermore, according to Figure 1 Combination Figure 4 As shown, the side of the first guide rail 312 facing the corrugated plate 200 is the lower surface of the first guide rail 312. The first connector 311 is connected to the side of the first guide rail 312 facing the corrugated plate 200, which can prevent the first guide rail 312 from interfering with the upper mold 23 on the first roller 21 to perform the pressing action.

[0069] Among them, such as Figure 5 As shown, the second actuation assembly 32 includes a second connector 321 and a second guide rail 322. Specifically, the second actuation assembly 32 is disposed below the corrugated plate 200 along the second direction Y, so that the second connector 321 can be connected to the second roller 22.

[0070] Furthermore, such as Figure 5 As shown, the length direction of the second guide rail 322 is the first direction X, and the second guide rail 322 is laid on one side of the second roller 22 along the length direction of the second roller 22. The second connector 321 is connected to one end of the second roller 22 along the length direction of the second roller 22, so that the second connector 321 can be connected to the second guide rail 322 and can roll along the length direction of the second guide rail 322, thereby driving the second roller 22 to roll along the first direction X, so that the lower mold 24 can perform multiple pressing along the first direction X. For example, the second action component 32 may include two second connectors 321, so that the two second connectors 321 are respectively connected to the two ends of the second roller 22 along the length direction of the second roller 22.

[0071] Furthermore, according to Figure 1 Combination Figure 5 As shown, the side of the second guide rail 322 facing the corrugated plate 200 is the upper surface of the second guide rail 322. The second connector 321 is connected to the side of the second guide rail 322 facing the corrugated plate 200, which can prevent the second guide rail 322 from interfering with the pressing action of the lower mold 24 on the second roller 22.

[0072] Furthermore, the lengths of the first guide rail 312 and the second guide rail 322 are both greater than or equal to the length of the corrugated plate 200. In other words, the displacement of the first roller 21 and the second roller 22 along the first direction X can cover the entire length of the corrugated plate 200, thereby allowing the pressing device 100 to press corrugations at any position along the length of the corrugated plate 200.

[0073] According to the description of the above embodiments, the first driving device 3 includes a first actuation component 31, a second actuation component 32, and two motors. The first actuation component 31 is connected to the first roller 21, and one motor drives the first actuation component 31 to make the first roller 21 roll along a first direction X. The second actuation component 32 is connected to the second roller 22, and the other motor drives the second actuation component 32 to make the second roller 22 roll along the first direction X. A first connecting member 311 is connected to one end of the first roller 21 along its length, driving the first roller 21 to roll along the first direction X, so that the upper mold 23 can perform multiple pressing along the first direction X. A second connecting member 321 is connected to one end of the second roller 22 along its length, driving the second roller 22 to roll along the first direction X, so that the lower mold 24 can perform multiple pressing along the first direction X. Furthermore, the first connector 311 is connected to the side of the first guide rail 312 facing the corrugated plate 200, and the second connector 321 is connected to the side of the second guide rail 322 facing the corrugated plate 200, so that the upper mold 23 and the lower mold 24 can smoothly perform multiple pressings along the first direction X, thereby enabling the pressing equipment 100 to smoothly complete the pressing of multiple corrugations on the corrugated plate 200.

[0074] Specifically, in some embodiments, gears are provided on the outer surfaces of both the first connector 311 and the second connector 321. A rack extending in the first direction X is provided on the side of the first guide rail 312 facing the corrugated plate 200. A rack extending in the first direction X is provided on the side of the second guide rail 322 facing the corrugated plate 200. The gear on the first connector 311 meshes with the rack in the first guide rail 312, causing the first connector 311 to roll in the first direction X. The gear on the second connector 321 meshes with the rack in the second guide rail 322, causing the second connector 321 to roll in the first direction X.

[0075] Specifically, the motor drives the first connector 311 / second connector 321 to rotate, causing the gears on the outer surfaces of the first connector 311 / second connector 321 to mesh with the racks on the first guide rail 312 / second guide rail 322. The gears roll along the extension direction of the racks, thereby driving the first roller 21 / second roller 22 to roll along the first direction X. The gear-rack meshing connection structure has high precision and good stability during rolling, which can further improve the positioning accuracy of the corrugations on the corrugated plate 200.

[0076] In other embodiments, such as Figure 4 and Figure 5 As shown, both the first connecting member 311 and the second connecting member 321 can be cylindrical gears, so there is no need to set additional gears on the first connecting member 311 and the second connecting member 321. One end of the cylindrical gear is connected to the first roller 21 or the second roller 22, and the other end meshes with the rack, thereby driving the first roller 21 and the second roller 22 to roll along the first direction X.

[0077] According to the description of the above embodiments, the gear on the outer surface of the first connector 311 / second connector 321 meshes with the rack on the first guide rail 312 / second guide rail 322. The gear rolls along the extension direction of the rack, thereby driving the first roller 21 / second roller 22 to roll along the first direction X. The gear-rack meshing connection structure has high precision and good stability during rolling, which can further improve the positioning accuracy of the corrugations on the corrugated plate 200.

[0078] In some embodiments, the second driving device 4 includes a third actuation assembly 41 and a fourth actuation assembly 42. The third actuation assembly 41 includes a third connector 411, a telescopic rod 43, and a hydraulic cylinder. The fourth actuation assembly 42 includes a fourth connector 421, the telescopic rod 43, and a hydraulic cylinder. The third connector 411 is sleeved on the first roller 21, and the fourth connector 421 is sleeved on the second roller 22. The telescopic rod 43 is connected to either the third connector 411 or the fourth connector 421. The hydraulic cylinder drives the telescopic rod 43 to extend or retract along the second direction Y.

[0079] Among them, such as Figure 6 As shown, the third actuation component 41 includes a third connector 411, a telescopic rod 43, and a hydraulic cylinder (not shown in the figure). The third connector 411 is sleeved on the first roller 21, allowing the first roller 21 to roll while connected to the third connector 411. Specifically, the third connector 411 is connected to one end of the first roller 21 along its length, avoiding interference with the pressing action of the upper mold 23 on the first roller 21. For example, the first actuation component 31 may include two third connectors 411, with the two third connectors 411 respectively connected to both ends of the first roller 21 along its length.

[0080] Among them, such as Figure 7As shown, the fourth actuation component 42 includes a fourth connector 421, a telescopic rod 43, and a hydraulic cylinder (not shown in the figure). The fourth connector 421 is sleeved on the second roller 22, allowing the second roller 22 to roll while connected to the fourth connector 421. Specifically, the fourth connector 421 is connected to one end of the second roller 22 along its length, avoiding interference with the pressing action of the lower mold 24 on the second roller 22. Exemplarily, the first actuation component 31 may include two third connectors 411, with the two third connectors 411 respectively connected to both ends of the first roller 21 along its length.

[0081] It should be noted that the mounting positions of the first connector 311 and the third connector 411 on the first guide rail 312 need to avoid each other to prevent interference. Similarly, the mounting positions of the second connector 321 and the fourth connector 421 on the second guide rail 322 need to avoid each other to prevent interference. For example, as shown... Figure 6 and Figure 7 As shown, one end of the first roller 21 / second roller 22 is first connected to the first connector 311 / second connector 321, and then connected to the third connector 411 / fourth connector 421. The third connector 411 / fourth connector 421 can also be directly fitted onto the first connector 311 / second connector 321.

[0082] Furthermore, the hydraulic cylinder drives the telescopic rod 43 to extend and retract along the second direction Y. The telescopic rod 43 is connected to the third connecting member 411 / fourth connecting member 421, which drives the third connecting member 411 / fourth connecting member 421 to move along the second direction Y, thereby causing the upper mold 23 / lower mold 24 to move toward the corrugated plate 200, thus completing one pressing action.

[0083] According to the description of the above embodiments, the second driving device 4 includes a third actuation component 41 and a fourth actuation component 42. The third actuation component 41 includes a third connector 411, a telescopic rod 43, and a hydraulic cylinder. The third connector 411 is sleeved on the first roller 21, enabling the first roller 21 to roll while connected to the third connector 411. The fourth actuation component 42 includes a fourth connector 421, a telescopic rod 43, and a hydraulic cylinder. The fourth connector 421 is sleeved on the second roller 22, enabling the second roller 22 to roll while connected to the fourth connector 421. The hydraulic cylinder drives the telescopic rod 43 to extend and retract along the second direction Y. The telescopic rod 43 is connected to the third connector 411 / fourth connector 421, causing the third connector 411 / fourth connector 421 to move along the second direction Y, thereby moving the upper mold 23 / lower mold 24 toward the corrugated plate 200, thus completing one pressing action.

[0084] In some embodiments, the clamping device 1 includes two pressure plates 11 parallel to the corrugated plate 200. The corrugated plate 200 is disposed between the two pressure plates 11. The side of the pressure plate 11 facing the corrugated plate 200 is provided with an anti-slip structure. A fastening bolt 12 is connected between the two pressure plates 11 to press the two pressure plates 11 tightly onto the corrugated plate 200.

[0085] like Figure 1 As shown, the clamping device 1 may include two pressure plates 11 parallel to the corrugated plate 200, with the corrugated plate 200 positioned between the two pressure plates 11. A fastening bolt 12 connects the two pressure plates 11. When the fastening bolt 12 is tightened, the two pressure plates 11 move towards the corrugated plate 200 until they press against the corrugated plate 200, thus fixing the corrugated plate 200. When the fastening bolt 12 is loosened, the two pressure plates 11 move away from the corrugated plate 200 until they no longer contact each other, allowing the corrugated plate 200 to be removed from between the two pressure plates 11. Therefore, the tightness of the clamping device 1 in holding the corrugated plate 200 can be adjusted by tightening the fastening bolt 12 to select a suitable tightness, ensuring the corrugated plate 200 remains stationary during the pressing process.

[0086] Furthermore, the side of the pressure plate 11 facing the corrugated plate 200 is provided with an anti-slip structure to enhance the friction between the pressure plate 11 and the corrugated plate 200, prevent the corrugated plate 200 from sliding between the pressure plates 11, and further ensure that the corrugated plate 200 can remain stationary during the pressing process.

[0087] According to the description of the above embodiment, the clamping device 1 places the corrugated plate 200 between two pressure plates 11. The tightness of the clamping device 1 clamping the corrugated plate 200 is adjusted by turning the fastening bolts 12 connecting the two pressure plates 11, so as to select a suitable tightness and keep the corrugated plate 200 stationary during the pressing process.

[0088] In some embodiments, to further improve the positioning accuracy of the corrugations on the corrugated plate 200, the pressing device 100 may also include, for example, Figure 1 The limiting device 5 is shown. The limiting device 5 includes two sets of abutment components 51, one set of abutment components 51 for limiting the position of the first roller 21, and the other set of abutment components 51 for limiting the position of the second roller 22. The abutment components 51 are disposed on the rolling path of the first roller 21 or the second roller 22, for limiting the first roller 21 or the second roller 22 to roll along the first direction X. The number of limiting devices 5 is equal to the number of corrugations.

[0089] The limiting device 5 includes two sets of abutment components 51, such as... Figure 8As shown, one set of abutment components 51 is used to limit the position of the first roller 21, thereby preventing the upper mold 23 from shaking in the first direction X when it performs the action of pressing corrugations, thus improving the positioning accuracy of the upper mold 23.

[0090] like Figure 9 As shown, another set of abutment components 51 is used to limit the position of the second roller 22, thereby preventing the lower mold 24 from shaking in the first direction X when it performs the action of pressing corrugations, thus improving the positioning accuracy of the lower mold 24.

[0091] In summary, the positioning accuracy of the upper mold 23 and the lower mold 24 has been improved, thereby further enhancing the positioning accuracy of the corrugations on the corrugated plate 200.

[0092] Specifically, the abutting component 51 is disposed on the rolling path of the first roller 21 or the second roller 22 to abut against the first roller 21 or the second roller 22 and restrict the first roller 21 or the second roller 22 from rolling in the first direction X. The first roller 21 moves along the length direction of the first guide rail 312, therefore, one set of abutting components 51 can be disposed on the first guide rail 312. Similarly, the second roller 22 moves along the length direction of the second guide rail 322, therefore, another set of abutting components can be disposed on the second guide rail 322.

[0093] Furthermore, the number of limiting devices 5 is equal to the number of corrugations. Specifically, multiple limiting devices 5 can be arranged along the first direction X so that the positions of the limiting devices 5 correspond one-to-one with the positions of the corrugations, thereby improving the positioning accuracy of all corrugations on the corrugated plate 200. For example, if four corrugations need to be pressed on the corrugated plate 200, the pressing equipment 100 includes four limiting devices 5 arranged along the first direction X.

[0094] According to the description of the above embodiments, the two sets of abutment components 51 in the limiting device 5 are respectively disposed on the rolling paths of the first roller 21 and the second roller 22 to limit the positions of the first roller 21 and the second roller 22, thereby improving the positioning accuracy of the upper mold 23 and the lower mold 24, and further improving the positioning accuracy of the corrugations on the corrugated plate 200. Furthermore, the number of limiting devices 5 is equal to the number of corrugations, so that the positions of the limiting devices 5 correspond one-to-one with the positions of the corrugations, thereby improving the positioning accuracy of all corrugations on the corrugated plate 200.

[0095] Specifically, in some embodiments, the abutment component 51 includes two snap-fit ​​blocks 511, which abut against the first roller 21 or the second roller 22. A plurality of snap-fit ​​grooves 512 distributed along a first direction X are provided on the surface of the first guide rail 312 facing the first roller 21. A plurality of snap-fit ​​grooves 512 distributed along the first direction X are provided on the surface of the second guide rail 322 facing the second roller 22. The snap-fit ​​blocks 511 are slidably connected in the snap-fit ​​grooves 512. The snap-fit ​​block 511 includes a first end 5111 and a second end 5112 disposed along a second direction Y. The first end 5111 protrudes along the second direction Y from the top of the first roller 21 or the bottom of the second roller 22. There is a gap between the second end 5112 and the groove wall of the snap-fit ​​groove 512, and an elastic member 513 connects the second end 5112 and the snap-fit ​​groove 512. The distance between the two snap-fit ​​blocks 511 is substantially equal to the dimensions of the first roller 21 and the second roller 22 in the first direction X.

[0096] Among them, such as Figure 8 As shown, the first guide rail 312 has multiple engaging grooves 512 distributed along the first direction X on the side facing the first roller 21. Engaging blocks 511 are slidably connected in the engaging grooves 512, so that two engaging blocks 511 are distributed along the first direction X, thereby enabling the engaging blocks 511 to abut against the first roller 21 in the first direction X, thus limiting the position of the first roller 21. Specifically, the engaging blocks 511 may have a protruding structure in the direction facing the first roller 21 for abutting against the first roller 21.

[0097] Similarly, such as Figure 9 As shown, the second guide rail 322 has multiple engaging grooves 512 distributed along the first direction X on the side facing the second roller 22. Engaging blocks 511 are slidably connected in the engaging grooves 512, so that two engaging blocks 511 are distributed along the first direction X, thereby enabling the engaging blocks 511 to abut against the second roller 22 in the first direction X, thus limiting the movement of the second roller 22. Specifically, the engaging blocks 511 may have a protruding structure in the direction facing the second roller 22 for abutting against the second roller 22.

[0098] Furthermore, such as Figure 8 and Figure 9 As shown, the snap-fit ​​block 511 includes a first end 5111 and a second end 5112 disposed along the second direction Y. The first end 5111 protrudes from the top of the first roller 21 or the bottom of the second roller 22 along the second direction Y, so that the snap-fit ​​block 511 can abut against the first roller 21 and the second roller 22.

[0099] There is a gap between the second end 5112 and the groove wall of the locking groove 512, allowing the locking block 511 to slide in the second direction Y within the locking groove 512, thereby causing the first roller 21 or the second roller 22 to pass over the locking block 511. Furthermore, as... Figure 8 and Figure 9 As shown, an elastic element 513 is connected between the second end 5112 and the snap-fit ​​groove 512, so that the first end 5111 of the snap-fit ​​block 511 can be reset by the elastic element 513, thereby allowing the first roller 21 or the second roller 22 to re-abut against the snap-fit ​​block 511, and thus allowing the first roller 21 or the second roller 22 to be flexibly snapped between any two snap-fit ​​blocks 511, thereby realizing the flexible positioning of the molding device 2.

[0100] Specifically, when the first roller 21 or the second roller 22 rolls, the top of the first roller 21 or the bottom of the second roller 22 applies pressure to the locking block 511 along the second direction Y. This pressure deforms the elastic element 513, causing the locking block 511 to slide towards the direction of the second end 5112 until the first end 5111 no longer protrudes from the top of the first roller 21 or the bottom of the second roller 22, allowing the first roller 21 or the second roller 22 to pass over the locking block 511. Furthermore, after the first roller 21 or the second roller 22 passes over the locking block 511, the restoring force of the elastic element 513 causes the movable locking block 511 to slide towards the direction of the first end 5111 until the first end 5111 protrudes from the top of the first roller 21 or the bottom of the second roller 22, allowing the locking block 511 to abut against the first roller 21 and the second roller 22. Specifically, the elastic element 513 can be a compression spring.

[0101] For example, when the first roller 21 or the second roller 22 passes one of the locking blocks 511, the first roller 21 or the second roller 22 is located between the two locking blocks 511. At this time, the distance between the two locking blocks 511 is substantially equal to the size of the first roller 21 and the second roller 22 in the first direction X, which can fix the first roller 21 or the second roller 22 between the two locking blocks 511, thereby restricting the position of the first roller 21 and the second roller 22, improving the positioning accuracy of the upper mold 23 and the lower mold 24, and further improving the positioning accuracy of the corrugations on the corrugated plate 200. In addition, when the first roller 21 or the second roller 22 passes the other locking block 511, it indicates that the pressing device 100 has completed the pressing of one corrugation and can start pressing the next corrugation.

[0102] Furthermore, the first end 5111 of the snap-fit ​​block 511 can be chamfered, which allows the first roller 21 or the second roller 22 to pass smoothly over the snap-fit ​​block 511, thereby ensuring that the corrugation pressing action can be carried out normally, and thus improving the production efficiency of the corrugated plate 200.

[0103] According to the description of the above embodiments, the abutment component 51 includes two snap-fit ​​blocks 511. A plurality of snap-fit ​​grooves 512 distributed along the first direction X are provided on the surface of the first guide rail 312 facing the first roller 21, and a plurality of snap-fit ​​grooves 512 distributed along the first direction X are provided on the surface of the second guide rail 322 facing the second roller 22. Both are used to connect the snap-fit ​​blocks 511, allowing the snap-fit ​​blocks 511 to abut against the first roller 21 or the second roller 22 in the first direction X, thereby limiting the positioning of the first roller 21 and the second roller 22. Further, the first end 5111 of the snap-fit ​​block 511 protrudes along the second direction Y from the top of the first roller 21 or the bottom of the second roller 22, so that the snap-fit ​​block 511 can abut against the first roller 21 and the second roller 22. There is a gap between the second end 5112 of the snap-fit ​​block 511 and the groove wall of the snap-fit ​​groove 512, and an elastic element 513 is connected between the second end 5112 and the snap-fit ​​groove 512, so that the snap-fit ​​block 511 is reset by the elastic element 513, thereby allowing the first roller 21 or the second roller 22 to be flexibly snapped between any two snap-fit ​​blocks 511, thereby realizing the flexible positioning of the molding device 2. Furthermore, the distance between the two snap-fit ​​blocks 511 is basically equal to the size of the first roller 21 and the second roller 22 in the first direction X, so that the first roller 21 or the second roller 22 can be fixed between the two snap-fit ​​blocks 511, thereby restricting the position of the first roller 21 and the second roller 22, improving the positioning accuracy of the upper mold 23 and the lower mold 24, and further improving the positioning accuracy of the corrugations on the corrugated plate 200.

[0104] Furthermore, the corrugated density of corrugated sheets 200 of different specifications is different, that is, the distance between two consecutive corrugations is different. In order to improve the versatility of the pressing equipment 100 and enable the pressing equipment 100 to press corrugated sheets 200 of various specifications, thereby reducing the production cost of corrugated sheets 200, the pressing equipment 100 in the embodiments of this application can also be designed as follows:

[0105] In some embodiments, a plurality of first slots 211 are provided on the first roller 21, and the plurality of first slots 211 are evenly distributed on the surface of the first roller 21. A plurality of second slots 221 are provided on the second roller 22, and the plurality of second slots 221 are evenly distributed on the surface of the second roller 22. The number of first slots 211 and second slots 221 is the same. The plurality of first slots 211 are used to connect to a plurality of upper molds 23, and the number of upper molds 23 is less than or equal to the number of first slots 211. The plurality of second slots 221 are used to connect to a plurality of lower molds 24, and the number of lower molds 24 is less than or equal to the number of second slots 221. The number of upper molds 23 and lower molds 24 is the same.

[0106] The first roller 21 has multiple first slots 211, and the multiple first slots 211 are evenly distributed on the surface of the first roller 21. Specifically, as shown... Figure 2 As shown, the first roller 21 is a cylindrical rod-shaped structure. The first slot 211 is disposed along the outer circumference of the cylinder. A connecting line exists between the center of the bottom of the first slot 211 and the axis of the first roller 21. A first angle exists between the connecting lines of any two adjacent first slots 211. The degree of the first angle is a divisor of 360°. The number of first slots 211 is the quotient of 360° divided by the first angle, and the number of first slots 211 is an integer, so that multiple first slots 211 can be evenly distributed on the surface of the first roller 21. For example, as... Figure 2 As shown, four first slots 211 are provided on the first roller 21, with a first angle of 90°. At this time, the four first slots 211 are evenly distributed on the surface of the first roller 21. For example, the number of first slots 211 can also be two, three, five or six, and no specific limitation is made here.

[0107] Since the number of second slots 221 is the same as the number of first slots 211, and multiple second slots 221 are provided on the second roller 22, and these multiple second slots 221 are evenly distributed on the surface of the second roller 22, it can be similarly understood that... Figure 2 As shown, the second roller 22 is a cylindrical rod-shaped structure. The second slot 221 is disposed along the outer circumference of the cylinder. A connecting line exists between the center of the bottom of the second slot 221 and the axis of the second roller 22. A first angle exists between the connecting lines of any two adjacent second slots 221. The degree of the first angle is a divisor of 360°. The number of second slots 221 is the quotient of 360° divided by the first angle, and the number of second slots 221 is an integer, so that multiple second slots 221 can be evenly distributed on the surface of the second roller 22. For example, as... Figure 2 As shown, four second slots 221 are provided on the second roller 22, with a first angle of 90°. At this time, the four second slots 221 are evenly distributed on the surface of the second roller 22. For example, the number of second slots 221 can also be two, three, five or six, and no specific limitation is made here.

[0108] In this configuration, multiple first slots 211 are used to connect multiple upper molds 23. Obviously, the number of upper molds 23 is less than or equal to the number of first slots 211. Furthermore, when multiple upper molds 23 are connected to the first slots 211, a second angle exists between two adjacent upper molds 23. Since the upper molds 23 are connected within the first slots 211, and a first angle exists between two adjacent first slots 211, the second angle is greater than or equal to the first angle, and the second angle is an integer multiple of the first angle. Specifically, when the number of upper molds 23 is equal to the number of first slots 211, the second angle is equal to the first angle. When the number of upper molds 23 is less than the number of first slots 211, the second angle is greater than the first angle.

[0109] The plurality of second slots 221 are used to connect a plurality of lower dies 24. Obviously, the number of lower dies 24 is less than or equal to the number of second slots 221. Furthermore, since the number of lower dies 24 is the same as the number of upper dies 23, when multiple lower dies 24 are connected in the second slots 221, a second angle exists between two adjacent lower dies 24. Because the lower dies 24 are connected within the second slots 221, and a first angle exists between two adjacent second slots 221, the second angle is greater than or equal to the first angle, and the second angle is an integer multiple of the first angle. Specifically, when the number of lower dies 24 is equal to the number of second slots 221, the second angle is equal to the first angle. When the number of lower dies 24 is less than the number of second slots 221, the second angle is greater than the first angle.

[0110] Furthermore, after the pressing device 2 completes the first corrugation pressing action, the first roller 21 rolls a distance equal to the first distance, and the upper mold 23 rotates to the top of the corrugated plate 200. Similarly, the second roller 22 rolls a distance equal to the first distance, and the lower mold 24 rotates to the bottom of the corrugated plate 200. At this time, the second corrugation pressing action is performed, so that the distance between the second pressed corrugation and the first pressed corrugation is the first distance.

[0111] When there is only one upper mold 23 and one lower mold 24, the first distance is the circumference of the outer circle of the first rolling shaft or the second rolling shaft. When there is more than one upper mold 23 and one lower mold 24, the ratio of the first distance to the circumference of the outer circle of the first rolling shaft is equal to the ratio of the second angle to 360°.

[0112] As described above, the longest distance between two consecutive pressings of corrugations depends on the circumference of the outer circles of the first roller 21 and the second roller 22. The shortest distance between two consecutive pressings of corrugations depends on the size of the first angle. Based on this, by adjusting the second angle to make it a multiple of the first angle, the distance between two consecutive pressings of corrugations can be flexibly adjusted to improve the versatility of the pressing equipment 100.

[0113] Specifically, the method for adjusting the second angle is as follows: adjust the distribution of the upper mold 23 / lower mold 24 on the first roller 21 / second roller 22. For example, when the two upper molds 23 / lower molds 24 are connected to adjacent first slots 211 / second slots 221, the second angle is equal to the first angle. Then, by adjusting the positions of the upper molds 23 / lower molds 24 so that they are connected to non-adjacent first slots 211 / second slots 221, the second angle is greater than the first angle, thus achieving the adjustment of the second angle.

[0114] Furthermore, the number of upper molds 23 and lower molds 24 will also change depending on the second angle. For example, when the first angle is 90°, the second angle can be either 90° or 180°. When the second angle is 90°, there are four upper molds 23 and four lower molds 24. When the second angle is 180°, there are two upper molds 23 and two lower molds 24. In other words, when the second angle is N times the first angle, the number of upper molds 23 and lower molds 24 will be N.

[0115] Based on this, the upper mold 23 is detachably connected to the first slot 211, and the lower mold 24 is detachably connected to the second slot 221, so that the number of the upper mold 23 and the lower mold 24 can be flexibly changed, thereby flexibly adjusting the distance between the corrugations of two consecutive pressings, so as to improve the versatility of the pressing equipment 100.

[0116] As described above, a plurality of first slots 211 evenly distributed on the surface of the first roller 21 are used to connect a plurality of upper dies 23. A plurality of second slots 221 evenly distributed on the surface of the second roller 22 are used to connect a plurality of lower dies 24. The number of first slots 211 and second slots 221 is the same, and the number of upper dies 23 and lower dies 24 is the same. The number of upper dies 23 is less than or equal to the number of first slots 211, and the number of lower dies 24 is less than or equal to the number of second slots 221. Therefore, by adjusting the distribution of the plurality of upper dies 23 / lower dies 24 on the first roller 21 / second roller 22, and by adjusting the number of upper dies 23 / lower dies 24, the distance between two consecutively pressed corrugations can be adjusted, thereby improving the versatility of the pressing equipment 100 and enabling the pressing equipment 100 to press corrugated sheets 200 of various specifications, thereby reducing the production cost of corrugated sheets 200.

[0117] Furthermore, the corrugation size on corrugated sheets 200 of different specifications is also different. In order to further improve the versatility of the pressing equipment 100 and enable the pressing equipment 100 to press corrugated sheets 200 of various specifications, thereby reducing the production cost of corrugated sheets 200, the pressing equipment 100 in the embodiments of this application can be designed as follows:

[0118] In some embodiments, the portion of the upper mold 23 that contacts the corrugated plate 200 is a raised structure. The portion of the lower mold 24 that contacts the corrugated plate 200 is a recessed structure. One upper mold 23 and one lower mold 24 constitute a pressing unit. Multiple raised structures have different dimensions, and multiple recessed structures have different dimensions. The dimensions of the raised structures and the dimensions of the recessed structures in a pressing unit correspond to each other.

[0119] As described above, the upper mold 23 and the lower mold 24 act on the corrugated plate 200 simultaneously, and the upper mold 23 presses the corrugated plate 200 into the lower mold 24, thereby forming a corrugation on the corrugated plate 200.

[0120] Specifically, the part of the upper mold 23 that contacts the corrugated plate 200 is a raised structure. The part of the lower mold 24 that contacts the corrugated plate 200 is a recessed structure. That is, the raised structure presses the corrugated plate 200 into the recessed structure, thereby pressing a corrugation onto the corrugated plate 200. Therefore, it can be understood that an upper mold 23 and a lower mold 24 can form a pressing unit, and one pressing unit is used to press one corrugation. Furthermore, the dimensions of the raised structure and the recessed structure in a pressing unit correspond to the dimensions of the recessed structure, so that the upper mold 23 can smoothly press the corrugated plate 200 into the lower mold 24, thereby completing the corrugation pressing.

[0121] Furthermore, since the pressing device 2 includes multiple upper molds 23 and multiple lower molds 24, and one upper mold 23 and one lower mold 24 can form a pressing unit, the pressing device 2 can include multiple pressing units. Multiple pressing units can be used to press corrugations of different sizes. Specifically, multiple protruding structures of different sizes can be set as upper molds 23 in different pressing units, and correspondingly multiple groove structures of different sizes can be set as lower molds 24 in different pressing units. This allows different pressing units to press corrugations of different sizes, further improving the versatility of the pressing equipment 100 and enabling the pressing equipment 100 to press corrugated plates 200 of various specifications, thereby reducing the production cost of the corrugated plates 200.

[0122] According to the description of the above embodiment, the part of the upper mold 23 that contacts the corrugated plate 200 is a raised structure, and the part of the lower mold 24 that contacts the corrugated plate 200 is a grooved structure. The raised structure presses the corrugated plate 200 into the grooved structure, thereby pressing a corrugation onto the corrugated plate 200. An upper mold 23 and a lower mold 24 constitute a pressing unit, and the dimensions of the raised structure and the grooved structure in a pressing unit correspond to each other, so that the upper mold 23 can smoothly press the corrugated plate 200 into the lower mold 24, thereby completing the corrugation pressing. Furthermore, multiple raised structures have different dimensions, and multiple grooved structures have different dimensions, so that the pressing device 2 can include multiple pressing units of different sizes for pressing corrugations of different sizes, further improving the versatility of the pressing equipment 100, enabling the pressing equipment 100 to press corrugated plates 200 of various specifications, thereby reducing the production cost of the corrugated plate 200.
