Description

Technical Field

[0001] This application relates to the field of tie rod processing and production, and in particular to an automatic feeding production line for flattening tie rods. Background Technology

[0002] Diagonal braces are commonly used in construction auxiliary tools, such as scaffolding. The function of scaffolding diagonal braces is to prevent scaffolding deformation. The combination of diagonal braces, horizontal bars, and vertical bars gives the scaffolding high stability and tensile strength within space.

[0003] The two ends of the round tube are flattened using a flattening machine to form a connecting plate, and through holes are drilled in the connecting plate. During scaffolding installation, the connecting plate is fastened to the connecting disc on the upright to maintain the stability of the scaffold structure. Its length is determined by the length of the upright and horizontal bar. In the processing of diagonal tie rods, batch processing is generally adopted. That is, several round tubes are conveyed to the flattening machine via a conveyor belt. Because it is difficult to accurately convey the round tubes to the flattening machine station during the conveying process, manual positioning is required. The tubes are then flattened and drilled using the flattening machine to complete the processing of the diagonal tie rod.

[0004] Regarding the aforementioned technologies, the inventors believe that because the number of diagonal tie rods processed is large, manual positioning is required for each flattening, resulting in low work efficiency. Summary of the Invention

[0005] To improve the problem of low work efficiency caused by the need for manual positioning, this application provides an automatic feeding production line for flattening inclined tie rods.

[0006] This application provides an automatic feeding production line for flattening tie rods, which adopts the following technical solution:

[0007] An automated feeding production line for flattening tie rods includes:

[0008] frame;

[0009] The feeding mechanism includes a conveying component and a pre-adjustment component, both mounted on the frame;

[0010] A flattening mechanism, mounted on the frame and located near the pre-adjustment assembly, is used to flatten both ends of the circular tube;

[0011] The pre-adjustment component is used to adjust and position the end of the circular tube.

[0012] By adopting the above technical solution, the round tube is conveyed by the feeding mechanism. During the conveying process, the position of the round tube is adjusted by the pre-adjustment component. Then, the round tube is continuously conveyed to the flattening machine by the conveying component, where it is flattened. Finally, the flattened round tube is conveyed by the unloading component. The pre-adjustment component can automatically adjust the round tube, thereby reducing manual adjustment, saving costs, and improving the processing efficiency of the tie rod.

[0013] Preferably, the conveying component is divided into a pre-conveying component and a quantitative conveying component, both of which are mounted on a frame, and the pre-adjustment component is located between the pre-conveying component and the quantitative conveying component.

[0014] The pre-adjustment assembly includes a positioning plate, an adjusting cylinder, and a push plate. The positioning plate is fixed to the frame, the adjusting cylinder is fixed to the other side of the frame in the width direction, the push plate is fixedly connected to the piston rod of the adjusting cylinder, one end of the round tube contacts the positioning plate, and the other end of the round tube contacts the push plate.

[0015] By adopting the above technical solution, several round tubes are conveyed to the pre-adjustment component through the pre-transfer component. The piston rod of the adjustment cylinder moves and the push plate is controlled to push the round tubes toward the positioning plate, so that the end of the round tube away from the push plate contacts the positioning plate. Then, the round tubes are continuously conveyed by the quantitative transfer component, and finally the end of the round tubes is flattened by the flattening machine.

[0016] Preferably, the pre-transfer assembly includes a conveyor belt and a first transfer frame, the conveyor belt is disposed on the frame, the first transfer frame is fixedly disposed on the frame, and the height of the transfer frame gradually decreases from the conveyor belt toward the pre-adjustment assembly.

[0017] The conveying direction of the round tube on the conveyor belt is perpendicular to the conveying direction on the conveyor frame.

[0018] By adopting the above technical solution, since the upper surface of the first conveyor is inclined, the round tube conveyed to the first conveyor by the conveyor belt can roll down along the inclined surface of the first conveyor to the pre-adjustment component. Then, the position of the round tube is adjusted by the pre-adjustment component, and then the round tube can be conveyed to the flattening machine by the quantitative conveying component.

[0019] Preferably, the quantitative conveying assembly includes a second conveyor frame and a conveyor seat. The second conveyor frame is fixed on the frame and connected to the end of the first conveyor frame away from the conveyor belt. The conveyor seat is disposed between the first and second conveyor frames. The frame is provided with a first driving member that drives the conveyor seat to slide and move up and down along the side wall of the second conveyor frame. The lifting and lowering of the conveyor seat is used to convey the round tube from the first conveyor frame to the second conveyor frame.

[0020] The upper surfaces of the conveyor base and the second conveyor frame are both inclined, and are in the same direction of inclination as the first conveyor frame.

[0021] When the conveyor seat is at its lowest point, the upper surface of the conveyor seat is not higher than the upper surface of the first conveyor frame;

[0022] When the conveyor seat is at its highest point, the upper surface of the conveyor seat is not lower than the upper surface of the second conveyor frame.

[0023] By adopting the above technical solution, the round tube rolls down onto the conveyor seat via the first conveyor frame. The first driving component drives the conveyor seat to lift the round tube. When the conveyor seat rises to the highest position, the round tube rolls down onto the second conveyor frame, which then conveys the round tube to the flattening machine.

[0024] Preferably, the second conveyor frame includes a fixed conveyor frame and a movable conveyor frame. The fixed conveyor frame is fixed to the frame and connected to the first conveyor frame. The fixed conveyor frame and the first conveyor frame are inclined in the same direction. The movable conveyor frame is disposed on the frame and located on the side of the fixed conveyor frame away from the first conveyor frame.

[0025] The frame is provided with a second driving component, which is connected to the mobile conveyor frame and is used to drive the mobile conveyor frame to move up and down; the frame is provided with a third driving component, which is connected to the second driving component and is used to drive the conveyor frame to move along the conveying direction of the circular tube.

[0026] The mobile conveyor is provided with several sets of first limiting slots, and each set of first limiting slots has several slots. The end of the mobile conveyor facing the fixed conveyor and the end of the fixed conveyor facing the mobile conveyor form an overlapping section.

[0027] By adopting the above technical solution, the round tube is conveyed to the fixed conveyor frame via a conveyor seat. Since there is an overlapping section between the fixed and moving conveyor frames, the round tube placed on the fixed conveyor frame will also be placed on the moving conveyor frame. A second driving component drives the moving conveyor frame to rise, thus separating the round tube from the fixed conveyor frame. Subsequently, a third driving component drives the second driving component to move, conveying the round tube to the flattening machine to flatten its ends. Several sets of first limiting grooves are provided, with a certain number in each set, to ensure quantitative conveying during each transfer. After the flattening machine completes the flattening of a batch of round tubes, another batch can be conveyed, thus completing the processing of the diagonal tie rods in an assembly line manner to improve production efficiency.

[0028] Preferably, an auxiliary adjustment support is provided on the frame and between the fixed conveyor and the flattening machine, the auxiliary adjustment support is provided with a plurality of second limiting grooves, and a limiting piece is provided on the frame and near the auxiliary adjustment support.

[0029] When the mobile conveyor is in its initial state, the height of the mobile conveyor is lower than the height of the auxiliary adjustment support.

[0030] Before the round tube is conveyed to the flattening machine, the round tube is placed in the second limiting groove and its end is in contact with the limiting piece.

[0031] By adopting the above technical solution, the third driving component drives the second driving component to move, and the second driving component drives the moving conveyor frame to move, thus moving the round tube from the fixed conveyor frame to the auxiliary adjustment support. The round tube on the auxiliary adjustment support is then moved to the flattening machine. After the round tube moves to the auxiliary adjustment support, it will be locked in the second limiting groove, moving the round tube toward the position of the limiting piece, and the end of the round tube will contact the limiting piece.

[0032] Preferably, a shearing machine is provided at one end of the conveyor belt away from the first conveyor frame, and a support plate is hinged on the frame and located on one side of the conveyor belt. The support plate extends along the outlet direction of the shearing machine, and a fourth driving member is provided on the frame. The fourth driving member is connected to the support plate and is used to drive the round tube placed on the support plate to be conveyed onto the conveyor belt.

[0033] A baffle is provided on the frame and on the side of the conveyor belt away from the support plate.

[0034] By adopting the above technical solution, since the diagonal tie rod is used in many occasions, the length of the diagonal tie rod will also change with the demand. In order to save materials, the appropriate length is cut by a shearing machine according to the usage requirements. In order to reduce the deformation of the round tube during shearing, the round tube will be supported by a support plate when it is conveyed from the shearing machine. After the round tube is placed on the support plate, the support plate is tilted by the fourth drive component, and the round tube will fall onto the conveyor belt.

[0035] Preferably, a push rod is provided on the frame at the end of the support plate away from the shearing machine, and a fifth driving member is provided on the frame to drive the push rod to move toward the first conveyor frame;

[0036] The side of the conveyor belt closer to the first conveyor frame is higher than the side of the conveyor belt farther from the first conveyor frame.

[0037] By adopting the above technical solution, in order to reduce the number of round tubes falling off the conveyor belt, the conveyor belt is set to an inclined state. After the round tube is conveyed to the end of the conveyor belt, the push rod is controlled by the fifth drive component to move forward and push the round tube onto the first conveyor frame.

[0038] Preferably, the frame is provided with an auxiliary adjustment component for adjusting the position of the circular tube. The auxiliary adjustment component is located close to the auxiliary adjustment support and is used to adjust the position of the circular tube placed on the auxiliary adjustment support.

[0039] The auxiliary adjustment component includes a first cam and a second cam, both of which are rotatably mounted on the frame and rotate coaxially.

[0040] The first cam includes a cam post and a cam groove. The axial direction of the cam post is consistent with the axial direction of the circular tube. The cam groove is spirally opened on the cam post. A support post is inserted into the cam groove. The end of the support post away from the cam post is in contact with the circular tube.

[0041] The cam groove is sequentially connected to the first starting rising section, the first adjusting moving section, the first stopping falling section, and the first resetting moving section. The support column is inserted into the cam groove to realize rising, adjusting the position of the circular tube by moving along the axial direction of the circular tube, falling, and resetting by moving along the axial direction of the circular tube.

[0042] The second cam includes a cam disk, on the circumference of which a third limiting groove is formed, and a lifting rod is inserted into the third limiting groove. The end of the lifting rod away from the cam disk is in contact with a circular tube.

[0043] The circumference of the cam disk is divided into a second initial rising section, a second adjustment moving section, a second stop falling section, and a second reset moving section. The second adjustment moving section and the second reset moving section are set at the same center. The lifting rod is inserted into the third limiting groove to achieve rising, stationary, falling, and stationary states.

[0044] By adopting the above technical solution, the circular tube is prone to positional changes during the conveying process. To improve the positional accuracy of the flattened circular tube, when the circular tube is conveyed to the auxiliary adjustment support, the first and second cams rotate, the support column rises, and the lifting rod also rises. When the support column and lifting rod rise, they raise the circular tube, causing the circular tube to disengage from the auxiliary adjustment support. Subsequently, under the continuous rotation of the first and second cams, the support column drives the circular tube to move towards the limiting plate, allowing the circular tube to abut against the limiting plate, so that the flattening machine can flatten the end of the circular tube. When the moving conveyor conveys the circular tube on the auxiliary adjustment support to the flattening machine, the first and second cams continue to rotate, the support column and lifting rod reset, waiting for the next adjustment of the circular tube's position.

[0045] In summary, this application includes at least one of the following beneficial technical effects:

[0046] 1. By setting a pre-adjustment component, the round tube can be automatically adjusted, thereby improving the processing efficiency of the tie rod;

[0047] 2. By setting up auxiliary adjustment components, the round tube can be further adjusted, thereby improving the processing efficiency of the tie rod;

[0048] 3. By setting up pre-feeding components and quantitative feeding components, round tubes can be quantitatively fed and flattened to achieve assembly line operation and improve processing efficiency. Attached Figure Description

[0059] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0060] This application discloses an automatic feeding production line for flattening tie rods.

[0061] Example 1

[0062] Reference Figure 1 An automatic feeding production line for flattening inclined tie rods includes a frame 1 and a feeding mechanism, a flattening machine 6, and a discharging mechanism 7, all mounted on the frame 1. The feeding mechanism includes a conveying component and a pre-adjustment component 4. The conveying component is mainly divided into a pre-conveyor component 2 and a quantitative conveyor component 3, with the pre-adjustment component 4 located between the pre-conveyor component 2 and the quantitative conveyor component 3. Several round tubes 8 for processing inclined tie rods are conveyed to the pre-adjustment component 4 via the pre-conveyor component 2. The position of the round tubes 8 is adjusted by the pre-adjustment component 4, and then the adjusted round tubes 8 are conveyed to the quantitative conveyor component 3. The quantitative conveyor component 3 conveys a certain amount of round tubes 8 to the flattening machine 6 for flattening the ends of the round tubes 8. Finally, the flattened round tubes 8 are conveyed by the flattening machine 6 through the discharging mechanism 7. In this embodiment, the quantitative conveyor component 3 conveys two round tubes 8 to the flattening machine 6 at a time. The discharging mechanism 7 includes a discharging conveyor frame 71, with the end of the discharging conveyor frame 71 inclined towards the ground away from the flattening machine 6. The flattened end of the round tube 8 is conveyed and stored by the unloading conveyor 71, thereby realizing the assembly line processing and improving the processing efficiency of the tie rod.

[0063] Reference Figure 2 The pre-transfer assembly 2 includes a conveyor belt 22 and a first transfer frame 28. A shearing machine 21 is provided at the end of the conveyor belt 22. The first transfer frame 28 is located on the side of the conveyor belt 22 away from the shearing machine 21 in the width direction. The conveying direction of the round tube 8 on the conveyor belt 22 is perpendicular to the conveying direction on the first transfer frame 28.

[0064] A support plate 23 and a push rod 26 are provided on the side of the conveyor belt 22 away from the first conveyor frame 28, and the support plate 23 and push rod 26 are distributed along the length of the conveyor belt 22. The support plate 23 is located near the shearing machine 21, and the push rod 26 is located near the first conveyor frame 28. The end of the support plate 23 near the shearing machine 21 is located at the entrance of the shearing machine 21, and the round tube 8 conveyed from the shearing machine 21 will first be supported by the support plate 23. One side of the support plate 23 in the width direction is hinged to the frame 1, and the other side of the support plate 23 extends towards the conveyor belt 22. The support plate 23 is located above the conveyor belt 22. A fourth driving member 24 supporting the support plate 23 is provided on the frame 1. In this embodiment, the fourth driving member 24 is a cylinder. The piston rod of the cylinder abuts against the bottom surface of the support plate 23. When the piston rod descends, the support plate 23 will descend onto the conveyor belt 22 by its own gravity. When the piston rod rises, the support plate 23 can be reset to a state that can support the round tube 8.

[0065] A baffle 25 is fixed on the frame 1 on the side of the conveyor belt 22 away from the support plate 23, and the height of the baffle 25 is higher than the height of the conveyor belt 22. When the round tube 8 falls from the support plate 23 onto the conveyor belt 22, the baffle 25 can block the round tube 8, making it difficult for the round tube 8 to detach from the conveyor belt 22. The conveyor belt 22 is inclined in the width direction, that is, the side of the conveyor belt 22 near the baffle 25 is higher than the side of the conveyor belt 22 away from the baffle 25, making it less likely for the round tube 8 to fall off when it is conveyed on the conveyor belt 22.

[0066] Push rod 26 is located at the end of support plate 23 away from shearing machine 21. A fifth driving member 27 is fixed on frame 1. In this embodiment, the fifth driving member 27 is a cylinder. The piston rod of the fifth driving member 27 is fixedly connected to the side of push rod 26 away from the first conveyor frame 28. When the round tube 8 is conveyed to the end of conveyor belt 22, the piston rod extends, thus pushing the round tube 8 onto the first conveyor frame 28. Pre-adjustment component 4 is located at the end of the first conveyor frame 28 away from conveyor belt 22. The side of the first conveyor frame 28 closer to conveyor belt 22 is higher than the side away from conveyor belt 22. Therefore, the round tube 8 rolling from conveyor belt 22 to the first conveyor frame 28 will roll along the inclined direction of the first conveyor frame 28 to the pre-adjustment component 4.

[0067] Reference Figure 2The pre-adjustment assembly 4 includes a positioning plate 41, an adjusting cylinder 42, and a push plate 43. The positioning plate 41 is fixed to the frame 1 and located on one side of the first conveyor frame 28. The adjusting cylinder 42 is fixed to the frame 1 and located on the other side of the first conveyor frame 28. The push plate 43 is fixed to the piston rod of the adjusting cylinder 42, and the push plate 43 and the positioning plate 41 are arranged parallel to each other. The round tube 8 that rolls to the end of the first conveyor frame 28 is pushed by the push plate 43 controlled by the adjusting cylinder 42, so that the end of the round tube 8 away from the push plate 43 abuts against the positioning plate 41. Then, when the quantitative conveying assembly 3 conveys the round tube 8, it can accurately fall into the working position of the flattening machine 6, thereby not only improving the working efficiency of the flattening machine 6, but also improving the flattening accuracy of the end of the round tube 8, making the flattening position of the end of the round tube 8 more accurate.

[0068] Reference Figure 3 and Figure 4 The quantitative conveying component 3 includes a second conveyor frame 31 and a conveyor seat 32. The second conveyor frame 31 is fixed to the frame 1 and is fixedly connected to the end of the first conveyor frame 28 away from the conveyor belt 22. The end of the second conveyor frame 31 near the first conveyor frame 28 is higher than the end of the first conveyor frame 28 near the second conveyor frame 31. A first driving member 33 is fixed on the frame 1. In this embodiment, the first driving member 33 is a cylinder. The first driving member 33 is located between the first conveyor frame 28 and the second conveyor frame 31 and is set along the height of the second conveyor frame 31. Two conveyor seats 32 are provided and are located inside the first conveyor frame 28 respectively. The conveyor seats 32 are fixed to the piston rod of the first driving member 33. The piston rod of the first driving member 33 rises and falls, which drives the conveyor seats 32 to slide along the side wall of the second conveyor frame 31 toward the side wall of the first conveyor frame 28.

[0069] The upper surface of the conveyor seat 32 is inclined, and its inclination direction is consistent with that of the first conveyor frame 28. When the piston rod is in the retracted state, the conveyor seat 32 is at its lowest point, and the upper surface of the conveyor seat 32 is not higher than the upper surface of the first conveyor frame 28. In this embodiment, the upper surface of the conveyor seat 32 is lower than the upper surface of the first conveyor frame 28. When the piston rod is in the extended state, the conveyor seat 32 is at its highest point, and the upper surface of the conveyor seat 32 is not lower than the upper surface of the second conveyor frame 31. In this embodiment, the upper surface of the conveyor seat 32 is higher than the upper surface of the second conveyor frame 31.

[0070] When the circular tube 8 rolls down from the first conveyor frame 28 to the end of the first conveyor frame 28 away from the conveyor belt 22, the circular tube 8 near the second conveyor frame 31 will also be located above the conveyor seat 32. In this embodiment, only two circular tubes 8 can be placed on the conveyor seat 32. The area of ​​the upper surface of the conveyor seat 32 can also be increased to increase the number of tubes conveyed by the conveyor seat 32 each time. Since the upper surface of the conveyor seat 32 is inclined, and the conveyor seat 32 slides along the side wall of the second conveyor frame 31 when the first driving member 33 drives the conveyor seat 32 to rise, two circular tubes 8 can be conveyed to the second conveyor frame 31 through the conveyor seat 32. Since the upper surface of the conveyor seat 32 is set as an inclined surface, when the height of the conveyor seat 32 exceeds that of the second conveyor frame 31, the circular tube 8 will descend along the inclined surface of the conveyor seat 32 onto the second conveyor seat 32.

[0071] Reference Figure 4 and Figure 5 The second conveyor frame 31 includes a fixed conveyor frame 311 and a movable conveyor frame 312. The fixed conveyor frame 311 is fixedly connected to the first conveyor frame 28, and the conveyor seat 32 slides along the side wall of the fixed conveyor frame 311 toward the first conveyor frame 28. The upper surface of the fixed conveyor frame 311 near the first conveyor frame 28 is inclined, and the inclination direction of the fixed conveyor frame 311 is consistent with the inclination of the conveyor seat 32. The movable conveyor frame 312 is slidably mounted on the frame 1, and the end of the movable conveyor frame 312 toward the fixed conveyor frame 311 and the end of the fixed conveyor frame 311 toward the movable conveyor frame 312 form an overlapping section 3122. When the height of the conveyor seat 32 exceeds that of the second conveyor frame 31, the circular tube 8 will descend along the inclined surface of the conveyor seat 32 onto the fixed conveyor frame 311, and then roll down along the inclined surface of the fixed conveyor frame 311 to the overlapping section 3122 of the fixed conveyor frame 311 and the movable conveyor frame 312.

[0072] The structures on both sides of the frame 1 in the width direction are arranged symmetrically with respect to the center line of the frame 1.

[0073] A second driving member 313 and a third driving member 314, and a support frame 315 connecting the first driving member 33 and the second driving member 313 are fixedly mounted on the frame 1. The support frame 315 is slidably mounted on the frame 1. In this embodiment, both the second driving member 313 and the third driving member 314 are cylinders. The second driving member 313 is fixed to the support frame 315, and the moving conveyor frame 312 is fixed to the piston rod of the second driving member 313. The moving conveyor frame 312 is provided with several sets of first limiting grooves 3121, and each set of first limiting grooves 3121 has several grooves. In this embodiment, each set of first limiting grooves 3121 has two grooves, and both ends of the circular tube 8 are placed in the corresponding first limiting grooves 3121. The second driving member 313 drives the support frame 315 to rise, thereby raising the moving conveyor frame 312 and raising the circular tube 8.

[0074] The third driving member 314 is fixed to the frame 1, and the piston rod of the third driving member 314 is fixedly connected to the support frame 315. The third driving member 314 and the second driving member 313 are arranged perpendicular to each other, that is, the third driving member 314 is arranged along the length direction of the frame 1. The extension and retraction of the piston rod of the third driving member 314 can drive the support frame 315 to convey the circular tube 8 placed in the first limiting groove 3121.

[0075] Reference Figure 6 Auxiliary adjustment support seats 51 are provided on both sides of the frame 1 in the width direction and near the flattening machine 6. Each auxiliary adjustment support seat 51 has several second limiting grooves 511. In this embodiment, each adjustment support seat has two second limiting grooves 511. Since the number of round tubes 8 being quantitatively conveyed is two, the number of second limiting grooves 511 on each adjustment support seat is determined according to the number of round tubes 8 being quantitatively conveyed. A limiting piece 512 is fixed on the frame 1 near any of the auxiliary adjustment support seats 51. When the round tube 8 is placed in the second limiting groove 511, one end of the round tube 8 abuts against the limiting piece 512. Then, when the round tube 8 is conveyed by the moving conveyor frame 312, the position of the round tube 8 at the flattening machine 6 will be more accurate. A placement seat is fixed on the frame 1 at the flattening machine 6 station. The placement seat has a groove for placing the round tube 8.

[0076] When the round tube 8 rolls down the inclined surface of the fixed conveyor frame 311 to the overlapping section 3122 of the fixed conveyor frame 311 and the moving conveyor frame 312, the second drive member 313 drives the support frame 315 to rise, placing the round tube 8 in the first limiting groove 3121 and separating the round tube 8 from the fixed conveyor frame 311. Subsequently, the third drive member 314 drives the second drive member 313 to move away from the first conveyor frame 28. After the third drive member 314 moves one stroke, the round tube 8 can be placed in the second limiting groove 511 of the auxiliary adjustment support seat 51. Then, the third drive member 314 drives the moving conveyor frame 312 to move another stroke, which can convey the round tube 8 on the auxiliary adjustment support seat 51 to the flattening machine 6. The round tube 8 located on the fixed conveyor frame 311 will also be conveyed to the auxiliary adjustment support seat 51, thus forming an assembly line to process the diagonal tie rod, thereby improving the production efficiency of the diagonal tie rod.

[0077] The implementation principle of the inclined tie rod flattening automatic feeding production line in this application embodiment is as follows: the round tube 8 is conveyed to the support plate 23 by the shearing machine 21 and rolls onto the conveyor belt 22. Then, the round tube 8 is pushed onto the first conveyor frame 28 by the push rod 26 and then placed on the side of the first conveyor frame 28 near the second conveyor frame 31 for storage, so as to realize the quantitative conveying of the second conveyor frame 31.

[0078] During quantitative conveying, the first driving component 33 drives the conveying seat 32 to raise the circular tube 8. When the conveying seat 32 reaches its highest position, the circular tube 8 rolls onto the fixed conveying frame 311. The second driving component 313 drives the moving conveying frame 312 to rise, thus disengaging the circular tube 8 from the fixed conveying frame 311. Then, the third driving component 314 drives the second driving component 313 to move, conveying the circular tube 8 to the auxiliary adjustment support seat 51. The position of the circular tube 8 is then adjusted. When the end of the circular tube 8 contacts the limiting piece 512, the third driving component 314 again drives the second driving component 313 to move to the flattening machine 6 to flatten the end of the circular tube 8. After flattening, the tube is unloaded via the unloading conveyor 71 and then collected.

[0079] Example 2

[0080] Reference Figure 7 The difference between this embodiment and Embodiment 1 is that an auxiliary adjustment assembly 5 is provided on the frame 1 and located on the second conveyor frame 31. The auxiliary adjustment assembly 5 includes an auxiliary adjustment plate 55, a first cam 53, and a second cam 54. The auxiliary adjustment plates 55 are located on both sides of the frame 1 in the width direction and on both sides of the fixed conveyor frame 311. Each auxiliary adjustment plate 55 consists of an adjustment plate 551 and a limiting plate 552 that are fixed to each other. The adjustment plate 551 is located on the side of the limiting plate 552 facing the first conveyor frame 28. The distance between the adjustment plates 551 on both sides of the frame 1 gradually decreases from the first conveyor frame 28 towards the second conveyor frame 31. The limiting plates 552 on both sides of the frame 1 are arranged parallel to each other. During the process of the round tube 8 entering the fixed conveyor frame 311 from the first conveyor frame 28, the round tube 8 will move from the adjustment plate 551 to the limiting plate 552, thereby limiting the position of the round tube 8 to be conveyed to the flattening machine 6, so that the position of the round tube 8 can be adjusted according to the first cam 53 and the second cam 54.

[0081] The first cam 53 and the second cam 54 are both rotatably mounted on the frame 1 and located between the two auxiliary adjustment support seats 51. The first cam 53 and the second cam 54 are used to further adjust the position of the round tube 8 between the two auxiliary adjustment support seats 51, so that the end of the round tube 8 can abut against the limiting piece 512, thereby improving the flattening accuracy of the end of the round tube 8.

[0082] Reference Figure 8A drive shaft 52 is mounted on the frame 1, and the axis of the drive shaft 52 is aligned with the axis of the circular tube 8 when it is conveyed by the second conveyor frame 31. A first cam 53 and a second cam 54 are both fixedly mounted on the drive shaft 52. A motor 521 is fixedly mounted on the frame 1, and the output shaft of the motor 521 is fixedly connected to the drive shaft 52. The first cam 53 is a spatial cam, comprising a cam post 531 and a cam groove 532. The cam groove 532 is spirally formed on the cam post 531 and is arranged in a closed loop. A support post 533 is inserted into the cam groove 532, with one end of the support post 533 extending towards the circular tube 8. A placement block 522 is connected to the end of the support post 533 away from the cam post 531. The side of the placement block 522 supporting the support post 533 has a placement groove for placing the circular tube 8.

[0083] Reference Figure 9 The cam groove 532 includes a first starting rising section, a first adjusting moving section, a first stopping falling section, and a first resetting moving section connected end to end. When the drive shaft 52 is rotated, the support column 533 is initially positioned in the first starting rising section. As the drive shaft 52 rotates, the support column 533 gradually rises. When the support column 533 moves to the first adjusting moving section, it stops rising. At this point, the support column 533 will move along the length of the drive shaft 52, thus driving the round tube 8 towards the limiting plate 512. If the round tube 8 contacts the limiting plate 512, but the support column 533 still moves towards the limiting plate 512, since the round tube 8 is only placed on the placement block 522, the round tube 8 moves on the placement block 522. Due to the auxiliary adjusting plate 55, the initial deviation range of the round tube 8 is controllable; therefore, there is no situation where the support column 533 has stopped moving while the round tube 8 has not yet contacted the limiting plate 512. When the support column 533 stops moving, it indicates that the circular tube 8 has been adjusted to the correct position. At this point, the support column 533 will be in the first stopping descent section. That is, with the continuous rotation of the drive shaft 52, the support column 533 will descend and then enter the first reset movement section. The support column 533 will move away from the limiting piece 512, thereby achieving reset. Specifically, the depth of the first initial rising section decreases from deep to shallow to facilitate the support column 533 stopping its ascent, the depth of the first adjusting movement section remains unchanged, the depth of the first stopping descent section increases from shallow to deep to facilitate the support column 533 descending, and the depth of the first reset movement section remains unchanged.

[0084] The second cam 54 includes a cam disk 541. A third limiting groove 542 is formed on the circumference of the cam disk 541. A lifting rod 543 is inserted into the third limiting groove 542. The end of the lifting rod 543 away from the cam disk 541 contacts the placement block 522. The circumference of the cam disk 541 is divided into a second initial rising section, a second adjustment moving section, a second stop falling section, and a second reset moving section. The second adjustment moving section and the second reset moving section are concentric. That is, when the support column 533 rises, the lifting rod 543 also rises. When the support column 533 drives the placement block 522 to translate in the direction of the limiting piece 512, the lifting rod 543 slides against the placement block 522, at which time the lifting rod 543 provides support for the placement block 522. When the support column 533 falls, the lifting rod 543 also falls. When the support column 533 drives the placement block 522 to move away from the limiting piece 512 to achieve reset, the lifting rod 543 remains stationary.

[0085] When the support column 533 is in the first initial rising section, the lifting rod 543 moves in the second initial rising section; when the support column 533 is in the first adjusting moving section, the lifting rod 543 moves in the second adjusting moving section; when the support column 533 is in the first stopping falling section, the lifting rod 543 moves in the second stopping falling section; when the support column 533 is in the first reset moving section, the lifting rod 543 moves in the second reset moving section.

[0086] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
