Technical Field
[0001] This application belongs to the technical field of corrugated sheet production equipment, specifically relating to a corrugated sheet forming device. Background Technology
[0002] Corrugated sheets are typically made from metal or paper, formed into a wavy sheet structure by the extrusion of two meshing, toothed rotating rollers. When processing raw materials of varying thicknesses, the current common method is to replace rollers of different sizes or reinstall and adjust their positions, which is time-consuming and results in low production efficiency. Furthermore, the fitting precision of the two rollers in current corrugated sheet production equipment is generally not high, and the unstable feeding direction of the raw materials leads to poor corrugated sheet forming quality. Utility Model Content
[0003] The purpose of this application is to provide a corrugated sheet forming device, which aims to solve the technical problems of low corrugated sheet production efficiency and poor corrugated sheet forming quality in the prior art.

[0006] The active frame includes a third fixed part and a fourth fixed part that are arranged at relative intervals, and the active roller is detachably installed between the third fixed part and the fourth fixed part; the second forming assembly also includes an active shaft, which is detachably inserted through the third fixed part, the active roller and the fourth fixed part, the active shaft is rotatably connected to the third fixed part and the fourth fixed part, and is circumferentially fixed to the active roller, and the power output end of the rotation drive assembly is connected to the active shaft.
[0007] Furthermore, the first fixing part is provided with a first connecting hole, and one end of the driven shaft is rotatably disposed in the first connecting hole; the first forming assembly also includes a first locking structure, which is threadedly connected to the first connecting hole and abuts against the end of the driven shaft located in the first connecting hole;
[0008] The third fixing part is provided with a third connecting hole, and one end of the drive shaft is rotatably disposed in the third connecting hole; the second forming component also includes a second locking structure, which is threadedly connected to the third connecting hole and abuts against the end of the drive shaft located in the third connecting hole.
[0009] Furthermore, the driven gear is provided with a first conical hole, the diameter of which decreases in the direction away from the first fixed part, and the driven shaft has a first conical section located in the first conical hole, the shape of which is adapted to the shape of the first conical hole;
[0010] The drive gear has a second conical hole, the diameter of which decreases in the direction away from the third fixed part. The drive shaft has a second conical section located inside the second conical hole, the shape of which is adapted to the shape of the second conical hole.
[0011] Furthermore, the guide assembly includes a first guide rod and a second guide rod. The first guide rod is fixedly connected to a third fixing part, and the second guide rod is fixedly connected to a fourth fixing part. The first fixing part is slidably sleeved on the first guide rod, and the second fixing part is slidably sleeved on the second guide rod.
[0012] Furthermore, the guide component is slidably mounted on the guide component and is located between the driven frame and the active frame.
[0013] Furthermore, the guiding component includes a guiding bracket and two limiting members. The guiding bracket is slidably disposed on the guiding component, and the two limiting members are installed on the guiding bracket at intervals, forming a limiting space between the two limiting members. The installation position of at least one limiting member on the guiding bracket is adjustable.
[0014] Furthermore, the limiting component includes a first limiting block, a second limiting block, and a threaded fastener. The first limiting block has a through hole, and the second limiting block has a threaded inner hole. The threaded fastener passes through the through hole and is threadedly connected to the threaded inner hole.

[0017] Compared with the prior art, the corrugated sheet forming apparatus provided in this application has the following advantages: During operation, the rotary drive assembly drives the active roller of the first forming assembly to rotate on the active frame. Since the active roller and the driven roller of the second forming assembly are meshed by teeth, the active roller can drive the driven roller to rotate on the driven frame. The raw material is squeezed by the active roller and the driven roller, thereby being pressed into a corrugated sheet with a wavy shape. When it is necessary to process raw materials of different thicknesses, the gap between the active roller and the driven roller can be adjusted by simply driving the driven frame to move closer to or further away from the first forming assembly through the linear drive assembly to accommodate raw materials of different thicknesses. The operation is simple and quick, without the need to replace active rollers and driven rollers of different sizes, nor the need to reinstall the active rollers and driven rollers and adjust their positions, thereby improving the production efficiency of corrugated sheets. By setting a guide component that slides through the driven frame, the driven frame can move stably along the target direction under the drive of the linear drive component. This ensures precise alignment between the driving and driven rollers, improving their fit and thus enhancing the forming quality of the corrugated sheet. Furthermore, by setting a guide component with a limiting space adapted to the size of the raw material, the raw material can be stably and accurately fed into the meshing point of the driving and driven rollers, further improving the forming quality of the corrugated sheet.

[0036] Corrugated sheets are typically made from metal or paper and formed into a wave-shaped sheet structure by being pressed by two meshing, rotating toothed rollers. Among them, metal corrugated sheets are widely used in modern aero-engines, new energy vehicles, electromagnetic shielding, rail transportation and other fields due to their advantages such as good electromagnetic shielding performance, good cushioning performance, lightweight and high strength and cost-effectiveness. From common engine honeycomb sealing rings, new energy battery guard plates, aerospace electromagnetic shielding boxes to lightweight and high-strength wall panels and flooring for rail transportation, metal corrugated sheets play an indispensable role.
[0037] When processing raw materials of varying thicknesses, the current common method is to replace rollers of different sizes or reinstall and adjust their positions, which is time-consuming and results in low production efficiency for corrugated sheets. Furthermore, the fitting precision of the two rollers in current corrugated sheet production equipment is generally not high, and the unstable feeding direction of raw materials further contributes to poor corrugated sheet forming quality.
[0038] In response to the above problems, combined with Figure 1 , Figure 2 and Figure 4 As shown, this application provides a corrugated sheet forming apparatus, including a linear drive assembly 10, a rotary drive assembly 20, a guide assembly 30, a guide assembly 40, a first forming assembly 50, and a second forming assembly 60. The first forming assembly 50 includes a driven frame 51 and a driven roller 52 rotatably disposed on the driven frame 51. The driven frame 51 is slidably connected to the guide assembly 30. The power output end of the linear drive assembly 10 is connected to the driven frame 51 and is used to drive the driven frame 51 to slide on the guide assembly 30 to approach or move away from the second forming assembly 60. The second forming assembly 60 includes an active frame 61 and an active roller 62 rotatably disposed on the active frame 61. The power output end of the rotary drive assembly 20 is connected to the active roller 62. The active roller 62 and the driven roller 52 are meshed by teeth. The guide assembly 40 is provided with a limiting space 41 for the raw material to pass through and adapted to the size of the raw material. The limiting space 41 is aligned with the meshing point of the active roller 62 and the driven roller 52.
[0039] During operation, the rotary drive assembly 20 drives the active roller 62 of the first forming assembly 50 to rotate on the active frame 61. Since the active roller 62 and the driven roller 52 of the second forming assembly 60 are meshed, the active roller 62 can drive the driven roller 52 to rotate on the driven frame 51. The raw material is compressed by the active roller 62 and the driven roller 52, thus being pressed into a corrugated sheet with a wavy shape. When processing raw materials of different thicknesses is required, the linear drive assembly 10 simply drives the driven frame 51 to move closer to or further away from the first forming assembly 50, adjusting the gap between the active roller 62 and the driven roller 52 to accommodate raw materials of different thicknesses. The operation is simple and quick, eliminating the need to replace active rollers 62 and driven rollers 52 of different sizes, or to reinstall and reposition them, thereby improving the production efficiency of corrugated sheets. By setting the guide component 30 to slide connection with the driven frame 51, the driven frame 51 can move stably along the target direction under the drive of the linear drive component 10, ensuring precise alignment between the drive roller 62 and the driven roller 52, improving the matching accuracy between the drive roller 62 and the driven roller 52, and thus improving the forming quality of the corrugated sheet. Furthermore, by setting the guide component 40, a limiting space 41 adapted to the size of the raw material is formed on the guide component 40, ensuring that the raw material enters the meshing point of the drive roller 62 and the driven roller 52 stably and accurately, thereby improving the forming quality of the corrugated sheet.
[0040] When it is necessary to adjust the specifications of corrugated sheets, such as flute height and flute pitch, it is usually necessary to replace the rollers with rollers of different specifications. Traditional corrugated sheet production equipment typically uses a frame assembled from multiple panels to mount the rollers. When replacing the rollers, the frame must be disassembled and reassembled, involving numerous and time-consuming steps, which is detrimental to improving the production efficiency of corrugated sheets. To address these problems, in some embodiments of this application, combined with... Figure 1 and Figure 2As shown, the driven frame 51 includes a first fixed part 511 and a second fixed part 512 arranged at relatively intervals, and the driven roller 52 is detachably installed between the first fixed part 511 and the second fixed part 512; the first forming assembly 50 also includes a driven shaft 53, which is detachably inserted through the first fixed part 511, the driven roller 52 and the second fixed part 512, and is rotatably connected to the first fixed part 511 and the second fixed part 512, and is circumferentially fixed to the driven roller 52; the active frame 61 includes a relatively... The third fixing part 611 and the fourth fixing part 612 are spaced apart, and the drive roller 62 is detachably installed between the third fixing part 611 and the fourth fixing part 612; the second forming assembly 60 also includes a drive shaft 63, which is detachably inserted through the third fixing part 611, the drive roller 62 and the fourth fixing part 612. The drive shaft 63 is rotatably connected to the third fixing part 611 and the fourth fixing part 612 and is circumferentially fixed to the drive roller 62. The power output end of the rotation drive assembly 20 is connected to the drive shaft 63.
[0041] When the driven roller 52 needs to be replaced, simply pull the driven shaft 53 out from the first fixing part 511, the driven roller 52, and the second fixing part 512. Then, the driven roller 52 can be pulled out from between the first fixing part 511 and the second fixing part 512. Next, the replacement driven roller 52 is placed between the first fixing part 511 and the second fixing part 512. Finally, the driven shaft 53 is installed so that it passes through the first fixing part 511, the driven roller 52, and the second fixing part 512. This completes the replacement of the driven roller 52 without disassembling the driven frame 51, which improves the replacement efficiency of the driven roller 52 and thus helps to improve the production efficiency of corrugated sheets. Similarly, when the drive roller 62 needs to be replaced, simply pull the drive shaft 63 out from the third fixing part 611, the drive roller 62, and the fourth fixing part 612. Then, the drive roller 62 can be pulled out from between the third fixing part 611 and the fourth fixing part 612. Next, place the replacement drive roller 62 between the third fixing part 611 and the fourth fixing part 612. Finally, install the drive shaft 63 so that it passes through the third fixing part 611, the drive roller 62, and the fourth fixing part 612. In this way, the replacement of the drive roller 62 can be completed without any disassembly of the drive frame 61, which improves the replacement efficiency of the drive roller 62 and thus helps to improve the production efficiency of corrugated sheets.
[0042] Since the drive shaft 63 and the drive roller 62 are circumferentially fixed, when the rotary drive assembly 20 drives the drive shaft 63 to rotate relative to the third fixed part 611 and the fourth fixed part 612, the drive shaft 63 can rotate synchronously with the drive roller 62. The drive roller 62 drives the driven roller 52 to rotate. Since the driven roller 52 and the driven shaft 53 are circumferentially fixed, the driven roller 52 can rotate synchronously with the driven shaft 53 relative to the first fixed part 511 and the second fixed part 512. Specifically, the drive shaft 63 and the drive roller 62 can be connected by a key to achieve circumferential fixation, and the driven shaft 53 and the driven roller 52 can also be connected by a key to achieve circumferential fixation.
[0043] In some embodiments, such as Figure 1 As shown, the driven frame 51 also includes a first connecting part 513, the two opposite ends of the first connecting part 513 being connected to the first fixing part 511 and the second fixing part 512 respectively. The first connecting part 513, the first fixing part 511 and the second fixing part 512 cooperate to form a U-shaped structure. The active frame 61 also includes a second connecting part 613, the two opposite ends of the second connecting part 613 being connected to the third fixing part 611 and the fourth fixing part 612 respectively. The second connecting part 613, the third fixing part 611 and the fourth fixing part 612 cooperate to form a U-shaped structure.
[0044] In some embodiments, combined with Figure 1 and Figure 2 As shown, the first fixing part 511 is provided with a first connecting hole 5111, the second fixing part 512 is provided with a second connecting hole 5121, one end of the driven shaft 53 is rotatably disposed in the first connecting hole 5111, and the other end of the driven shaft 53 is rotatably disposed in the second connecting hole 5121; the first forming assembly 50 also includes a first locking structure 54, which is threadedly connected to the first connecting hole 5111 and abuts against the end of the driven shaft 53 located in the first connecting hole 5111; the third fixing part 611 is provided with a third connecting hole 6111, the fourth fixing part 612 is provided with a fourth connecting hole 6121, one end of the drive shaft 63 is rotatably disposed in the third connecting hole 6111, and the other end of the drive shaft 63 passes through the fourth connecting hole 6121 and is connected to the rotary drive assembly 20; the second forming assembly 60 also includes a second locking structure 64, which is threadedly connected to the third connecting hole 6111 and abuts against the end of the drive shaft 63 located in the third connecting hole 6111.
[0045] When replacing the driven roller 52, first rotate the first locking structure 54. The threaded engagement between the first locking structure 54 and the first connecting hole 5111 causes the first locking structure 54 to move away from the driven shaft 53. After completely removing the first locking structure 54 from the first connecting hole 5111, the driven shaft 53 can be pulled out. This allows the driven shaft 53 to sequentially exit the second connecting hole 5121, the hole of the driven roller 52, and the first connecting hole 5111. Then, the replacement driven roller 52 is placed into the first fixing part 5. Between the 11 and the second fixing part 512, the driven shaft 53 is installed, so that the driven shaft 53 passes through the first connecting hole 5111 and the hole of the driven roller 52 in sequence and is inserted into the second connecting hole 5121. Finally, the first locking structure 54 is installed into the first connecting hole 5111. The first locking structure 54 is rotated so that the first locking structure 54 abuts against the end of the driven shaft 53 located in the first connecting hole 5111 to axially limit the driven shaft 53. In this way, the replacement of the driven roller 52 is completed. The operation is simple and quick. When the drive roller 62 needs to be replaced, first rotate the second locking structure 64. The threaded engagement between the second locking structure 64 and the third connecting hole 6111 causes the second locking structure 64 to move away from the drive shaft 63. After completely removing the second locking structure 64 from the third connecting hole 6111, the drive shaft 63 can be pulled out. The drive shaft 63 is then pulled out sequentially from the fourth connecting hole 6121, the hole of the drive roller 62, and the third connecting hole 6111. Finally, the replacement drive roller 62 is placed into the third fixed... Between part 611 and the fourth fixing part 612, install the drive shaft 63, so that the drive shaft 63 passes through the third connecting hole 6111, the hole of the drive roller 62 and the fourth connecting hole 6121 in sequence. Finally, install the second locking structure 64 into the third connecting hole 6111, rotate the second locking structure 64 so that the second locking structure 64 abuts against the end of the drive shaft 63 located in the third connecting hole 6111 to axially limit the drive shaft 63. In this way, the replacement of the drive roller 62 is completed. The operation is simple and quick.
[0046] In some embodiments, such as Figure 2 As shown, the first molding assembly 50 further includes a first bearing 55 and a second bearing 56. The first bearing 55 is disposed in the first connecting hole 5111 and sleeved on the driven shaft 53, and the second bearing 56 is disposed in the second connecting hole 5121 and sleeved on the driven shaft 53, thereby supporting the driven shaft 53 and allowing the driven shaft 53 to rotate relative to the first fixed part 511 and the second fixed part 512. The second molding assembly 60 further includes a third bearing 65 and a fourth bearing 66. The third bearing 65 is disposed in the third connecting hole 6111 and sleeved on the drive shaft 63, and the fourth bearing 66 is disposed in the fourth connecting hole 6121 and sleeved on the drive shaft 63, thereby supporting the drive shaft 63 and allowing the drive shaft 63 to rotate relative to the third fixed part 611 and the fourth fixed part 612.
[0047] In some embodiments, a first axial positioning surface facing the driven roller 52 is formed in the first connecting hole 5111, and a second axial positioning surface facing the driven roller 52 is formed in the second connecting hole 5121. The opposite sides of the first bearing 55 abut against the first axial positioning surface and one side of the driven roller 52, respectively, and the opposite sides of the second bearing 56 abut against the second axial positioning surface and the other side of the driven roller 52, respectively, thereby achieving axial positioning of the first bearing 55, the driven roller 52, and the second bearing 56. A third axial positioning surface facing the driving roller 62 is formed in the third connecting hole 6111, and a fourth axial positioning surface facing the driving roller 62 is formed in the fourth connecting hole 6121. The opposite sides of the third bearing 65 abut against the third axial positioning surface and one side of the driving roller 62, respectively, and the opposite sides of the fourth bearing 66 abut against the fourth axial positioning surface and the other side of the driving roller 62, respectively, thereby achieving axial positioning of the third bearing 65, the driving roller 62, and the fourth bearing 66.
[0048] In some embodiments, the driven shaft 53 has a first flange at one end located in the first connecting hole 5111, and the first flange abuts against the side of the first bearing 55 facing away from the driven roller 52, thereby forming axial positioning; the drive shaft 63 has a second flange at one end located in the third connecting hole 6111, and the second flange abuts against the side of the third bearing 65 facing away from the drive roller 62, thereby forming axial positioning.
[0049] In some embodiments, such as Figure 2As shown, the driven gear has a first conical hole 521, the diameter of which decreases in the direction away from the first fixed part 511. The driven shaft 53 has a first conical section located inside the first conical hole 521, the shape of which is adapted to the shape of the first conical hole 521. The driving gear has a second conical hole 621, the diameter of which decreases in the direction away from the third fixed part 611. The driving shaft 63 has a second conical section located inside the second conical hole 621, the shape of which is adapted to the shape of the second conical hole 621. When installing the driven shaft 53, the driven shaft 53 is sequentially inserted into the first connecting hole 5111, the first tapered hole 521, and the second connecting hole 5121. Then, the first locking structure 54 is installed in the first connecting hole 5111. Rotating the first locking structure 54 pushes the driven shaft 53 to move, so that the first tapered section of the driven shaft 53 fits tightly with the first tapered hole 521 to achieve tension, thereby achieving axial fixation of the driven shaft 53. The cooperation between the first tapered section and the first tapered hole 521 can achieve high-precision cooperation between the driven shaft 53 and the driven roller 52, which is beneficial to improving the forming quality of the corrugated sheet. When installing the drive shaft 63, insert the drive shaft 63 into the third connecting hole 6111, the second tapered hole 621 and the fourth connecting hole 6121 in sequence. Then, install the second locking structure 64 into the third connecting hole 6111. Rotate the second locking structure 64 to push the drive shaft 63 to move, so that the second tapered section of the drive shaft 63 fits tightly with the second tapered hole 621 to achieve tension, thereby achieving axial fixation of the driven shaft 53. The cooperation between the second tapered section and the second tapered hole 621 can achieve high-precision cooperation between the drive shaft 63 and the drive roller 62, which is beneficial to improving the forming quality of the corrugated sheet.
[0050] In some embodiments, such as Figure 2As shown, the first locking structure 54 includes a first locking nut 541 and a first thrust bearing 542. The first locking nut 541 is threadedly connected to the first connecting hole 5111, and the opposite sides of the first thrust bearing 542 abut against the ends of the first locking nut 541 and the driven shaft 53, respectively. The second locking structure 64 includes a second locking nut 641 and a second thrust bearing 642. The second locking nut 641 is threadedly connected to the third connecting hole 6111, and the opposite sides of the second thrust bearing 642 abut against the ends of the second locking nut 641 and the drive shaft 63, respectively. When installing the driven shaft 53, firstly, the driven shaft 53 is sequentially inserted into the first connecting hole 5111, the first tapered hole 521, and the second connecting hole 5121. Then, the first thrust bearing 542 is installed on one end of the driven shaft 53 located in the first connecting hole 5111. Next, the first locking nut 541 is inserted into the first connecting hole 5111. By rotating the first locking nut 541, the driven shaft 53 is axially compressed by the first thrust bearing 542, so that the first tapered section of the driven shaft 53 is tightly fitted with the first tapered hole 521 of the driven roller 52 to achieve tension. When installing the drive shaft 63, first insert the drive shaft 63 into the third connecting hole 6111, the second tapered hole 621 and the fourth connecting hole 6121 in sequence, and install the second thrust bearing 642 on the end of the drive shaft 63 located in the third connecting hole 6111. Then, insert the second locking nut 641 into the third connecting hole 6111 and rotate the second locking nut 641. The second thrust bearing 642 axially compresses the drive shaft 63, so that the second tapered section of the drive shaft 63 fits tightly with the second tapered hole 621 of the drive roller 62 to achieve tension.
[0051] In some embodiments, both the first locking nut 541 and the second locking nut 641 have an internal hexagonal hole in the middle. When it is necessary to install or remove the first locking nut 541 and the second locking nut 641, a hexagonal wrench can be inserted into the internal hexagonal hole to facilitate the rotation of the first locking nut 541 and the second locking nut 641, thereby improving the efficiency of installation and removal.
[0052] In some embodiments, such as Figure 2As shown, the driven shaft 53 has a first threaded hole 531 at one end located in the first connecting hole 5111, and the axial direction of the first threaded hole 531 is consistent with the axial direction of the first connecting hole 5111. The drive shaft 63 has a second threaded hole 631 at one end located in the third connecting hole 6111, and the axial direction of the second threaded hole 631 is consistent with the axial direction of the third connecting hole 6111. When it is necessary to disassemble the driven shaft 53, a tool with external threads can be inserted into the first threaded hole 531 of the driven shaft 53. Since the drive shaft 63 is locked by the rotary drive assembly 20 and cannot rotate, the rotation of the drive roller 62, the driven roller 52, and the driven shaft 53 is restricted. Therefore, when the tool is rotated, the driven shaft 53 can be driven to move linearly along the axial direction, which facilitates the disassembly of the driven shaft 53 and improves the disassembly and assembly efficiency. When it is necessary to disassemble the drive shaft 63, a tool with external threads can be inserted into the second threaded hole 631 of the drive shaft 63. Since the drive shaft 63 is locked by the rotary drive assembly 20 and cannot rotate, rotating the tool can drive the drive shaft 63 to move linearly along the axial direction, which facilitates the disassembly of the drive shaft 63 and improves the efficiency of disassembly and assembly. Specifically, the rotary drive assembly 20 includes a motor with a self-locking function, and the output shaft of the motor is connected to the drive shaft 63 through a coupling 110.
[0053] In some embodiments, such as Figure 3 As shown, the guide assembly 30 includes a first guide rod 31 and a second guide rod 32. The first guide rod 31 is fixedly connected to a third fixing part 611, and the second guide rod 32 is fixedly connected to a fourth fixing part 612. The first fixing part 511 is slidably sleeved on the first guide rod 31, and the second fixing part 512 is slidably sleeved on the second guide rod 32. By having the first fixing part 511 slidably sleeved on the first guide rod 31 and the second fixing part 512 slidably sleeved on the second guide rod 32, and with the first fixing part 511 and the second fixing part 512 located on opposite sides of the driven gear, the stability and accuracy of the moving direction of the driven frame 51 can be improved, thereby improving the fitting accuracy between the driven roller 52 and the driving roller 62. The number of the first guide rod 31 and the second guide rod 32 is not limited; there can be one or more. For example, the figure shows two first guide rods 31 and two guide rods 32.
[0054] In some embodiments, such as Figure 3As shown, the guide assembly 30 also includes a first guide sleeve 33 and a second guide sleeve 34. The first guide sleeve 33 is fixed inside both the first fixing part 511 and the third fixing part 611, and the second guide sleeve 34 is fixed inside both the second fixing part 512 and the fourth fixing part 612. The first guide sleeve 33 is slidably sleeved on the first guide rod 31, and the second guide sleeve 34 is slidably sleeved on the second guide rod 32. The high-precision fit between the first guide sleeve 33 and the first guide rod 31, and the high-precision fit between the second guide sleeve 34 and the second guide rod 32, can improve the stability and accuracy of the moving direction of the driven frame 51.
[0055] In some embodiments, such as Figure 1 As shown, the guide component 40 is slidably disposed on the guide component 30 and located between the driven frame 51 and the driving frame 61. After adjusting the gap between the driving roller 62 and the driven roller 52, or after replacing the driving roller 62 and the driven roller 52 with different specifications, the guide component 40 can be slid on the guide component 30 to adjust the position of the guide component 40, ensuring that the limiting space 41 of the guide component 40 is aligned with the meshing point of the driving roller 62 and the driven roller 52, thereby ensuring that the raw material enters the meshing point of the driving roller 62 and the driven roller 52 stably and accurately, improving the forming quality of the corrugated sheet.
[0056] In some embodiments, such as Figure 4 As shown, the guide assembly 40 includes a guide bracket 42 and two limiting members 43. The guide bracket 42 is slidably disposed on the guide assembly 30, and the two limiting members 43 are spaced apart and installed on the guide bracket 42, forming a limiting space 41 between the two limiting members 43. The installation position of at least one limiting member 43 on the guide bracket 42 is adjustable. By adjusting the installation position of the limiting member 43 on the guide bracket 42, the distance between the two limiting members 43 can be adjusted, thereby adjusting the size of the limiting space 41 to accommodate raw materials of different specifications. Specifically, the guide bracket 42 is slidably sleeved on the first guide rod 31 and the second guide rod 32. The guide bracket 42 has a third threaded hole 4211 and a fourth threaded hole 4221 respectively corresponding to the positions of the first guide rod 31 and the second guide rod 32. By screwing screws into the third threaded hole 4211 and the fourth threaded hole 4221, the screws abut against the first guide rod 31 and the second guide rod 32, so that the guide bracket 42 can be stably fixed on the first guide rod 31 and the second guide rod 32 to ensure stable feeding of raw materials.
[0057] In some embodiments, combined with Figure 4 and Figure 5As shown, the limiting member 43 includes a first limiting block 431, a second limiting block 432, and a threaded fastener 433. The first limiting block 431 has a through hole 4311, and the second limiting block 432 has a threaded inner hole 4321. The threaded fastener 433 passes through the through hole 4311 and is threadedly connected to the threaded inner hole 4321. The first limiting block 431 and the second limiting block 432 cooperate to clamp the guide bracket 42. When it is necessary to adjust the distance between the two limiting members 43, loosen the threaded fastener 433, and then adjust the position of the first limiting block 431 and the second limiting block 432 on the guide bracket 42. After adjusting to the appropriate position, align the through hole 4311 of the first limiting block 431 and the threaded inner hole 4321 of the second limiting block 432. Then tighten the threaded fastener 433 so that the threaded fastener 433 passes through the through hole 4311 and is aligned with the threaded inner hole 4321. Under the action of the threaded fastener 433, the first limiting block 431 and the second limiting block 432 cooperate to clamp the guide bracket 42, thereby stably fixing the limiting member 43 on the guide bracket 42.
[0058] In some embodiments, such as Figure 4 As shown, the guide bracket 42 includes a first sliding seat 421, a second sliding seat 422, a first limiting post 423, and a second limiting post 424. The first sliding seat 421 and the second sliding seat 422 are both slidably connected to the guide assembly 30. Specifically, the first sliding seat 421 is slidably sleeved on the first guide rod 31, and the second sliding seat 422 is slidably sleeved on the second guide rod 32. The first limiting post 423 and the second limiting post 424 are spaced apart along the extension direction of the guide assembly 30, that is, the length direction of the first guide rod 31 and the second guide rod 32. The two ends of the first limiting post 423 are respectively connected to the first sliding seat 421 and the second sliding seat 422, and the two ends of the second limiting post 424 are respectively connected to the first sliding seat 421 and the second sliding seat 422. Two limiting members 43 are spaced apart along the length direction of the first limiting post 423 and the second limiting post 424. The first limiting block 431 and the second limiting block 432 of the limiting members 43 cooperate to clamp the first limiting post 423 and the second limiting post 424. When the raw material passes through the space formed by the first limiting post 423, the second limiting post 424, and the two limiting members 43, the two limiting members 43 can restrict the movement of the raw material along the length direction of the first limiting post 423 and the second limiting post 424, while the first limiting post 423 and the second limiting post can restrict the movement of the raw material along the length direction of the first guide rod 31. This enhances the limiting effect on the raw material, ensuring that the raw material enters the meshing point of the driving roller 62 and the driven roller 52 stably and accurately, thus improving the forming quality of the corrugated sheet. Specifically, the third threaded hole 4211 is opened in the first sliding seat 421, and the fourth threaded hole 4221 is opened in the second sliding seat 422.
[0059] In some embodiments, such as Figure 1As shown, the corrugated sheet forming device also includes at least one pair of cooperating guide wheels 70, which are positioned upstream of the guide component 40 along the feeding direction of the raw material. During the feeding process, the guide wheels 70 guide and constrain the raw material through contact and friction with the surface of the raw material, causing it to move along a predetermined path. This prevents the raw material from deviating or wrinkling during feeding, ensuring that the raw material enters the limiting space 41 of the guide component 40 stably and accurately.
[0060] In some embodiments, such as Figure 1 As shown, the corrugated sheet forming device also includes a first mounting bracket 80, a second mounting bracket 90 and a third mounting bracket 100. The linear drive assembly 10 is mounted on the first mounting bracket 80, the active frame 61 is mounted on the second mounting bracket 90, the rotary drive assembly 20 is mounted on the third mounting bracket 100, the ends of the first guide rod 31 and the second guide rod 32 away from the active frame 61 are both fixed on the first mounting bracket 80, and the guide wheel 70 is rotatably mounted on the first mounting bracket 80.
[0061] In some embodiments, the linear drive assembly 10 includes a cylinder, the power output end of which is connected to the driven frame 51. Using a cylinder to drive the driven frame 51 provides sufficient pressure to ensure a tight fit between the driven roller 52 and the driving roller 62, thereby improving the forming quality of the corrugated sheet. By precisely adjusting the cylinder pressure, the processing requirements of raw materials with different thicknesses and hardnesses can be met. Compared to electric cylinders, cylinders have advantages such as high output force, simple structure, small footprint, and low cost.
[0062] It should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
