[0033] In order to enable those skilled in the art of this technology to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or there can also be another intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be another intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific implementation manners and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Example 1, please refer to Figure 1 , Figure 2 and Figure 3, High-speed corrugated pipe on-line automatic punching and cutting machine, including a cutting box 1. There are corresponding conveying holes 11 for the corrugated pipe to pass through at both ends of the cutting box 1. Inside the cutting box 1, there are symmetrically distributed conveyor belts 2 that can rotate synchronously in opposite directions. The conveyor belts 2 are used to drive the corrugated pipe for conveying. Inside the cutting box 1, there are also multiple punching rods 32 that can move back and forth and are used for punching holes on the surface of the corrugated pipe. Inside the cutting box 1, there is also an adjusting plate 42 that can move back and forth. At the bottom of the adjusting plate 42, there is a cutting knife 471 that can move up and down. And at the bottom of the adjusting plate 42, there is also a clamping arc plate 46 that can move back and forth and is used for clamping the corrugated pipe.

[0037] The rotation of the conveyor belt 2 can realize the automatic conveying of the corrugated pipe. The reciprocating movement of the punching rod 32 can realize the automatic punching of the corrugated pipe. At the same time, the reciprocating movement of the adjusting plate 42 can make the corrugated pipe, when it needs to be cut, through the synchronous movement of the adjusting plate 42 and the corrugated pipe, so that the cutting knife 471 and the corrugated pipe can maintain a relatively static state. In this way, when the cutting knife 471 cuts, it will not affect the normal conveying of the corrugated pipe. Such a design can enable the cutting knife 471 to cut a relatively thick corrugated pipe, and when the cutting knife 471 cannot quickly cut the corrugated pipe, such a cutting method can not only realize the cutting of the corrugated pipe, but also not stop the conveying of the corrugated pipe during the cutting process. In this way, it can fully improve the overall cutting efficiency.

[0038] The design of the clamping arc plate 46 that can move back and forth can make the clamping arc plate 46 fix the corrugated pipe through the mutual fitting of the clamping arc plate 46 when the cutting knife 471 is cutting. Such a design ensures the stability of the cutting knife 471 when cutting the corrugated pipe and prevents the corrugated pipe from deforming during the cutting process.

[0039] Wherein, inside the cutting box 1, there is a fixedly connected punching plate 3. On the punching plate 3, there are through holes 31 for the corrugated pipe to pass through. Outside the through holes 31, there are multiple fixedly connected punching motors 33 on the punching plate 3. The output end of the punching motor 33 drives the punching rod 32 to reciprocate through a linear reciprocating mechanism. Since it is a common prior art in the field that the punching motor 33 drives the punching rod 32 to reciprocate through a linear reciprocating mechanism, this application does not describe this specific structure in too much detail. At the same time, inside the cutting box 1, there is a conveying motor for driving the conveyor belt 2 to rotate.

[0040] Please refer to Figure 1 、 Figure 2, in this embodiment, a fixed frame 4 which is fixedly connected and U-shaped is arranged in the cutting box 1. A diversion rod 44 which is fixedly connected is arranged in the fixed frame 4. Diversion grooves 424 which are slidably connected with the diversion rod 44 are arranged at both ends of the adjusting plate 42. A driving mechanism for driving the adjusting plate 42 to move back and forth is further arranged in the fixed frame 4. The design of the diversion rod 44 can make the adjusting plate 42 more stable when moving back and forth, improving the overall stability. A first hole 45 for the bellows to pass through is arranged on the fixed frame 4.

[0041] Please refer to Figure 2 and Figure 3 , Figure 4 , in this embodiment, the driving mechanism includes a driving shaft 43. The driving shaft 43 is rotatably arranged in the fixed frame 4. A driving thread is arranged on the driving shaft 43. An adjusting hole 421 for the driving shaft 43 to pass through is arranged on the adjusting plate 42. A semicircular connecting arc plate 422 is arranged in the adjusting hole 421. The connecting arc plate 422 is arranged to be movable back and forth in the adjusting hole 421, and a thread groove matching the driving thread is arranged on the inner wall of the connecting arc plate 422. A return spring 441 for driving the adjusting plate 42 to automatically return to the initial position is further arranged in the fixed frame 4. One side of the fixed frame 4 is provided with a driving motor 41 for driving the driving shaft 43 to rotate.

[0042] The design of the driving thread and the two connecting arc plates 422 can realize the movement control of the adjusting plate 42 by the rotation of the driving thread. The design of the two connecting arc plates 422 being movable back and forth and the return spring 441 can make the adjusting plate 42 separate from the driving thread and the thread groove through the separation of the two connecting arc plates 422 after cutting is completed. At this time, the clamping restriction of the connecting arc plate 422 is released. In this way, through the elasticity of the return spring 441, the adjusting plate 42 can quickly return to the initial position, waiting for the next cutting and conveying more quickly and efficiently. And after the adjusting plate 42 returns to the initial position, the connecting arc plate 422 automatically closes, realizing the automatic connection of the adjusting plate 42 for the next time.

[0043] If the adjusting plate 42 is in the conventional screw conveying mode, after the adjusting plate 42 finishes cutting, it takes a certain amount of time to return to the initial position. If this time is too long, either the conveying speed of the bellows needs to be adjusted to cut the bellows of a set length, or the cutting length of the bellows needs to be increased, and it is impossible to cut the relatively short bellows. With the design of the present application, it can effectively make up for the disadvantage that the time for the adjusting plate 42 to return to the initial position is too long during the conventional forward and reverse control of the screw. It has the stability of screw conveying during cutting, and at the same time, during the process of returning to the initial position, it can effectively reduce the overall time, can cut the relatively short bellows, and does not need to reduce the conveying rate of the bellows.

[0044] Please refer to Figure 2 and Figure 3 , in this embodiment, a plurality of fixedly connected second hydraulic rods 423 are arranged in the adjusting hole 421, and the second hydraulic rods 423 are fixedly connected to the connecting arc plate 422. The second hydraulic rods 423 can realize the control of the reciprocating movement of the connecting arc plate 422.

[0045] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , in this embodiment, a communicating guide pipe 4251 is arranged between the liquid inlet ends of the plurality of second hydraulic rods 423. An adjusting groove 425 is arranged in the adjusting plate 42. A piston plate 4252 which is slidably and sealingly connected is arranged in the adjusting groove 425. A communicating liquid is filled between the adjusting groove 425 and the guide pipe 4251. A pressing telescopic mechanism is fixedly connected in the adjusting groove 425. A connecting rod 4253 is arranged at the telescopic end of the pressing telescopic mechanism 4254, and the connecting rod 4253 is fixedly connected to the piston plate 4252. A pressing rod 4255 is connected to the pressing end of the pressing telescopic mechanism 4254. A bendable connecting piece is arranged at the end of the pressing rod 4255, and the extending end of the connecting piece is connected to the cutting knife 471. A first groove 427 is arranged on one side of the adjusting plate 42. A first rod 420 which is slidably and sealingly connected is arranged in the first groove 427. A second groove communicating with the adjusting groove 425 is arranged at one end of the first groove 427. A second rod 426 which is slidably and sealingly connected is arranged in the second groove. The second rod 426 is located above the pressing rod 4255. The first groove 427 and the second groove between the second rod 426 and the first rod 420 are filled with hydraulic liquid. Among them, the pressing telescopic mechanism 4254 adopts the pressing telescopic mechanism 4254 in the existing field of pressing ballpoint pens. This is the prior art, so the present application will not describe it in too much detail.

[0046] The design of the pressing and telescoping mechanism 4254, piston plate 4252, pressing rod 4255, connecting member, first rod 420 and second rod 426 enables the cutting blade 471 to automatically press the pressing rod 4255 through the connecting member after cutting. In this way, through the characteristics of the pressing and telescoping mechanism 4254, the automatic movement of the adjusting plate 42 is realized. The movement of the piston plate 4252 can drive the synchronous contraction of multiple second hydraulic rods 423 through hydraulic linkage, thereby realizing the automatic separation of the connecting arc plate 422. In this way, the automatic separation of the connecting arc plate 422 after cutting can be achieved. During the process of the adjusting plate 42 returning to its initial position under the action of the return spring 441, due to inertia, the adjusting plate 42 will automatically squeeze the return spring 441 when returning to its initial position. During this process, the first rod 420 can contact and squeeze the inner wall of the fixed frame 4, which can drive the second rod 426 to automatically extend through hydraulic transmission, thereby performing a secondary press on the pressing rod 4255. In this way, through the characteristics of the pressing and telescoping mechanism 4254, the piston plate 4252 is driven to return to its initial position, causing multiple second hydraulic rods 423 to automatically extend, and the two connecting arc plates 422 to automatically approach and close each other. Due to its elasticity, the return spring 441 will cause the adjusting plate 42 to approach and squeeze towards the driving thread 431. By rotating the driving shaft 43, the rapid threaded connection between the driving thread 431 and the connecting arc plate 422 can be realized. At this time, the automatic return of the adjusting plate 42 to its initial position is achieved. Such a design realizes the automatic release of the limit fixation of the connecting arc plate 422 after cutting, and after the adjusting plate 42 returns to its initial position, the automatic closing of the connecting arc plate 422 and the automatic threaded connection after closing.

[0047] Please refer to Figure 3 In this embodiment, a cutting groove 47 is provided at the bottom of the adjusting plate 42, and a third hydraulic rod 472 fixedly connected thereto is provided in the cutting groove 47. The third hydraulic rod 472 is rotatably connected to the cutting blade 471. The third hydraulic rod 472 realizes the automatic cutting of the cutting blade 471.

[0048] Please refer to Figure 6 and Figure 7 In this embodiment, an installation plate 473 fixedly connected thereto is provided at the end of the third hydraulic rod 472. A hinge 474 is rotatably connected to one side of the installation plate 473 and the cutting blade 471. A positioning groove 477 is provided on the other side of the installation plate 473. A positioning plate 475 fixedly connected thereto and matching the positioning groove 477 is provided on the cutting blade 471. A card slot is provided on one side of the positioning plate 475, and a retractable card rod 478 engaging with the card slot is provided on one side of the positioning groove 477.

[0049] Please refer to Figure 6 and Figure 7, in this embodiment, a first card slot 479 is provided on one side of the positioning slot 477. The clamping rod 478 is slidably and sealingly arranged in the first card slot 479. A second card slot communicating with the first card slot 479 is provided on the mounting plate 473. A linkage rod 476 is slidably and sealingly arranged in the second card slot. The linkage rod 476 is fixedly connected to the connecting piece.

[0050] The design that the cutting knife 471 is rotatably connected to the mounting plate 473 enables the cutting knife 471 to separate the connecting arc plate 422 before rising after cutting is completed by the rotation of the cutting knife 471. This can further reduce the time required in the original process of returning to the initial position. Moreover, in the way of rotation, the cutting knife 471 will not affect the normal conveying of the corrugated pipe during the backward movement.

[0051] The design of the clamping rod 478, the linkage rod 476 and the connecting piece enables the connecting piece to preferentially pull the linkage rod 476 to move before the cutting knife 471 completes cutting. Through the hydraulic transmission, the clamping rod 478 automatically contracts. At this time, the clamping rod 478 automatically releases the connection and fixation between the positioning plate 475 and the positioning slot 477. When the cutting knife 471 completely rises, due to the weight of the cutting knife 471, it will remain vertical. At this time, by the continuous rising of the cutting knife 471, through the extrusion of the linkage rod 476, the clamping rod 478 can be automatically extended, and the clamping rod 478 is automatically inserted into the card slot, realizing the automatic fixation of the cutting knife 471.

[0052] Please refer to Figure 3 , in this embodiment, fixed plates 461 which are symmetrically distributed and fixedly connected are provided at the bottom of the adjusting plate 42. A fourth hydraulic rod 462 is fixedly connected to the fixed plates 461. The end of the fourth hydraulic rod 462 is fixedly connected to the clamping arc plate 46.

[0053] When this embodiment is in use:

[0054] First, the corrugated pipe is fed into the cutting box 1 through the conveying hole 11, and the conveyor belt 2 clamps and conveys the corrugated pipe. At this time, by controlling the rotation of the conveyor belt 2, the corrugated pipe can be conveyed in the cutting box 1. When the corrugated pipe passes through the through hole 31 and reaches the punching rod 32, the punching motor 33 drives the punching rod 32 to automatically punch the corrugated pipe;

[0055] After punching is completed, the corrugated pipe passes through the adjusting hole 421 and passes through the fixed frame 4, and then is automatically discharged through another conveying hole 11;

[0056] When the bellows reaches the set length, control the drive motor 41 to drive the conveying shaft 52 to rotate, so that the adjusting plate 42 and the cutting position of the bellows move synchronously, so that the cutting knife 471 and the cutting position remain relatively stationary. At this time, control the third hydraulic rod 472 to drive the cutting knife 471 to automatically cut the cutting position of the bellows;

[0057] When the cutting is completed, the connecting piece can pull the linkage rod 476 upward. Through the hydraulic transmission, the clamping rod 478 automatically contracts, so that the clamping rod 478 is separated from the clamping groove. At this time, the cutting knife 471 and the mounting plate 473 are in a rotatable connection state. Then continue to control the third hydraulic rod 472 to make the cutting knife 471 continue to move downward a set distance, so that the connecting piece can pull the pressing rod 4255 to automatically contract. At this time, through the characteristics of the pressing telescopic mechanism 4254, the adjusting plate 42 can move automatically. Through the hydraulic transmission, a plurality of second hydraulic rods 423 can automatically contract, so that the two connecting arc plates 422 are automatically separated. At this time, the connection between the connecting arc plate 422 and the driving thread 431 is automatically released. The elasticity of the return spring 441 can drive the adjusting plate 42 to automatically return to the initial position. At this time, the cutting knife 471 and the mounting plate 473 are rotationally connected. Therefore, when the adjusting plate 42 moves back, even if the cutting knife 471 is still rising, the cutting knife 471 will automatically rotate and will not affect the automatic conveying of the bellows;

[0058] When the adjusting plate 42 moves back to the return spring 441, due to inertia, the adjusting plate 42 will automatically squeeze the return spring 441, so that the connecting arc plate 422 will move to one end of the driving thread 431. At this time, the first rod 420 contacts and presses against the side wall of the fixed frame 4. Thus, through the hydraulic transmission, the second rod 426 can press the pressing rod 4255 again, so that the piston plate 4252 automatically returns to the initial position. Through the hydraulic transmission, the second hydraulic rod 423 automatically extends, so that the connecting arc plate 422 can move to before the driving thread 431, and the connecting arc plate 422 can automatically close. In this way, the elasticity of the return spring 441 can squeeze the connecting arc plate 422, and under the rotation of the driving thread 431, the connecting arc plate 422 and the driving thread 431 can be quickly connected;

[0059] Through the above method, automatic punching of the bellows and automatic cutting and separation of the bellows after reaching the set length can be achieved.

[0060] For Embodiment 2, the same parts as in Embodiment 1 will not be described. The differences from Embodiment 1 are as follows: Please refer to Figure 8, in this embodiment, the driving mechanism includes a driving ring bar 5. A rotatable driving ring bar 5 is provided above the fixed frame 4. A plurality of telescopic first hydraulic rods 51 are provided on the driving ring bar 5. The end of the first hydraulic rod 51 is fixedly connected with a top plate 53 for abutting and conveying the adjusting plate 42. A reset spring 441 for driving the adjusting plate 42 to return to its initial position is provided on one side of the fixed frame 4. The reset spring 441 is sleeved on the diversion rod 44. A rotatably connected conveying shaft 52 is provided in the cutting box 1. The conveying shaft 52 is used to drive the conveying ring bar to rotate. A first motor for driving the conveying shaft 52 to rotate is further provided in the cutting box 1.

[0061] The designs of the driving ring bar 5, the first hydraulic rod 51 and the top plate 53 realize the periodic reciprocating motion of a plurality of top plates 53 through the rotation of the driving ring bar 5. The designs of the top plate 53 and the first hydraulic rod 51 can realize the selective elongation of the top plate 53. In this way, before the top plate 53 moves to the adjusting plate 42, the first hydraulic rod 51 elongates, so that the top plate 53 elongates. When the top plate 53 moves to the adjusting plate 42, the automatic movement of the adjusting plate 42 can be realized by the extrusion of the top plate 53 on the adjusting plate 42. After cutting is completed, the automatic separation of the top plate 53 and the adjusting plate 42 can be realized by the contraction of the first hydraulic rod 51. Cooperating with the reset spring 441, the adjusting plate 42 can quickly return to its initial position. Such a design not only realizes the synchronous movement of the cutting knife 471 during cutting, but also enables the adjusting plate 42 to quickly return to its initial position after cutting is completed, and can cut relatively short bellows. However, since the positions between the driving ring bar 5 and the first hydraulic rod 51 cannot be adjusted, the reciprocating motion period of the top plate 53 cannot be adjusted, which has certain limitations.

[0062] Embodiment 3, the same parts as those in Embodiment 1 will not be described. The differences from Embodiment 1 are as follows: in this embodiment, the driving mechanism includes a driving shaft 43. The driving shaft 43 is rotatably connected in the fixed frame 4. A reciprocating thread is provided on the driving shaft 43. The adjusting plate 42 is provided with an adjusting hole 421 for the driving shaft 43 to pass through and is connected with the reciprocating thread in a matching manner. A driving motor 41 for driving the driving shaft 43 to rotate is provided on one side of the fixed frame 4.

[0063] The design of the drive motor 41, drive shaft 43, and reciprocating thread enables the periodic reciprocating motion of the adjusting plate 42 through the characteristics of the reciprocating thread. However, due to the limitations of screw conveyance, it takes a relatively long time for the adjusting plate 42 to reciprocate, resulting in the inability to cut relatively short bellows. At the same time, since the conveyance speed of the bellows is constant, and the movement speed of the adjusting plate 42 needs to be consistent with the conveyance speed of the bellows, therefore, the periodic reciprocating motion of the adjusting plate 42 is fixed, which leads to the inability to cut bellows of different lengths.
