[0057] In this embodiment, the bracket 1 is used to install, fix and support components such as the slitting device 2, that is, the bracket 1 provides an installation foundation for components such as the slitting device 2. It can be understood that the bracket 1 can be a structure such as a frame, a machine table, a mounting frame, a mounting table, a mounting plane or a plate body, which is not limited herein.

[0058] It can be understood that the bracket 1 is used to place or convey the pipe 7. In order to facilitate automatic slitting and achieve automatic segmented cutting according to requirements, a transmission mechanism or a conveying mechanism is arranged on the bracket 1. The transmission mechanism or the conveying mechanism is used to convey the pipe 7 to the slitting device 2, and use the slitting device 2 for slitting, and then continue to convey it to the next working station after completion. In this embodiment, the bracket 1 has a feeding end and a discharging end, that is, the pipe 7 enters from the feeding end of the bracket 1, and after being slit by the slitting device 2, it enters the next process through the discharging end.

[0059] In this embodiment, by setting the slitting device 2 as the cutting mechanism 21 and the hammering mechanism 22, the cutting mechanism 21 and the hammering mechanism 22 are arranged at intervals and are located above the pipe 7 on the bracket 1, so as to facilitate the cooperation of the cutting mechanism 21 and the hammering mechanism 22 to slit the pipe 7. It can be understood that the cutting mechanism 21 and the hammering mechanism 22 can be installed on the bracket 1 through a support frame or a gantry, so that a space for the pipe 7 to pass through is formed between the cutting mechanism 21 and the hammering mechanism 22 and the bracket 1.

[0060] It can be understood that in order to realize the automatic cutting of the cutting mechanism 21, the cutting mechanism 21 includes a first driving member 211, a lifting platform 212 and a cutter assembly 213. The first driving member 211 is fixed on the bracket 1. For example, it can be fixed on the bracket 1 through structures such as a support frame or a gantry, or can be fixed on the bracket 1 through the base structure of the slitting device 2 itself, which is not limited herein.

[0061] In this embodiment, the first driving member 211 is used to provide driving force for the lifting platform 212 and the cutter assembly 213. The first driving member 211 can be a driving cylinder, a driving module, a lifting structure, etc. As long as it can drive the lifting platform 212 to drive the cutter assembly 213 to approach or move away from the bracket 1 to cut the pipe 7, any structure is acceptable and will not be limited here.

[0062] It can be understood that the lifting platform 212 is connected to the output end of the first driving member 211. The lifting platform 212 can be a plate-like structure or a block-like structure, which will not be limited here. The lifting platform 212 is used to both install and fix the cutter assembly 213 and provide a force-bearing for the hammering of the hammer block 222 of the hammering mechanism 22. In this embodiment, the cutter assembly 213 can be a cutter, a blade, etc. In order to facilitate cutting at multiple positions, the cutter assembly 213 can also be set to include multiple cutters or blade structures. In order to facilitate the integration of multiple cutters or blade structures into one body, the cutter assembly 213 further includes a tool holder and other structures, which will not be limited here.

[0063] In this embodiment, in order to realize the automatic hammering operation of the hammering mechanism 22, the hammering mechanism 22 includes a second driving member 221 and a hammer block 222. The hammer block 222 is connected to the output end of the second driving member 221. The second driving member 221 drives the hammer block 222 to hammer the lifting platform 212 so that the cutter assembly 213 performs secondary cutting on the pipe 7. It can be understood that the hammering mechanism 22 can be fixed to the bracket 1 through structures such as a bracket or a gantry, or can also be fixed to the bracket 1 through the base structure of the slitting device 2 itself, which will not be limited here.

[0064] Of course, for the sake of convenience and simplified structure, the second driving member 221 of the hammering mechanism 22 and the first driving member 211 are fixed to the same bracket or mounting structure, which will not be limited here.

[0065] It can be understood that the second driving member 221 is used to provide driving force for the hammering of the hammer block 222. The second driving member 221 can be a driving cylinder, a driving module, a lifting structure, etc. As long as it can drive the hammer block 222 to hammer the lifting platform 212 so that the cutter assembly 213 performs secondary cutting on the pipe 7, any structure is acceptable and will not be limited here. In this embodiment, the pipe 7 can be a marked pipe material, a tape or a sheet, etc., which will not be limited here.

[0066] The pipe cutting device 100 of the present invention is provided with a slitting device 2 on the bracket 1, so that the cutting mechanism 21 and the hammering mechanism 22 of the slitting device 2 are arranged at intervals and are located above the pipe 7 on the bracket 1. In this way, it is convenient to use the cutting mechanism 21 to first perform the first cutting on the pipe 7 conveyed by the bracket 1, that is, the first driving member 211 of the cutting mechanism 21 drives the lifting platform 212 to drive the cutter assembly 213 to cut the pipe 7, so as to make a notch on the pipe 7 for the first time. Then, the hammering mechanism 22 is used to hammer the cutting mechanism 21, so that the cutting mechanism 21 continues to perform the second cutting on the pipe 7, that is, the second driving member 221 of the hammering mechanism 22 drives the hammer block 222 to hammer the lifting platform 212, so that the cutter assembly 213 cuts the pipe twice, making the incisions of the second cutting exactly the same, thus completing the entire cutting process. It can be understood that through the secondary cutting, the pipe cutting device 100 has high cutting accuracy and smooth incisions, avoiding incomplete cutting or burrs on the marked pipe material during one-time cutting, and has high practicability.

[0067] In this embodiment, as Figure 10 shown, the bracket 1 includes a slitting base and two limiting plates. The two limiting plates are arranged at intervals on the slitting base and form a material passing channel. It can be understood that when the pipe 7 extends into the material passing channel, it can assist the pipe 7 to move to directly below the slitting device 2, prevent the pipe 7 from running off track, and ensure the cutting accuracy.

[0068] To further improve the cutting accuracy and prevent the pipe 7 from running off track, in an embodiment, the surface of the limiting plate located inside the material passing channel is provided with a limiting groove, and the side of the pipe 7 extends into the limiting groove. It can be understood that by providing the limiting groove, not only can the problem of the pipe 7 running off track during transportation be effectively prevented, but also the cutter assembly 213 of the slitting device 2 can be prevented from driving the pipe 7 to move upward during cutting.

[0069] It can be understood that the slitting base of the bracket 1 has a feeding end and a discharging end. The limiting plate can be arranged at one end of the slitting base adjacent to the feeding end, or can be arranged at one end of the slitting base adjacent to the discharging end; or the limiting plates are simultaneously arranged at one end of the slitting base adjacent to the feeding end and one end of the slitting base adjacent to the discharging end, which is not limited herein.

[0070] In one embodiment, the slitting device 2 further includes a base mechanism 23. The base mechanism 23 includes a fixed base 231 and a plurality of limiting baffles 232. Among them, the fixed base 231 is provided on the bracket 1 and is arranged opposite to and spaced apart from the bracket 1. The cutting mechanism 21 and the hammering mechanism 22 are arranged on the side of the fixed base 231 facing away from the bracket 1. The fixed base 231 is provided with a through hole 2311 corresponding to the cutter assembly 213. The through hole 2311 allows the cutter assembly 213 to pass through to cut the pipe 7. The plurality of limiting baffles 232 are arranged on the side of the fixed base 231 facing the bracket 1 and are parallel to each other along the traveling direction of the pipe 7. The plurality of limiting baffles 232 are located on opposite sides of the through hole 2311, so that the limiting baffles 232 and the fixed base 231 enclose a pipe channel, and the through hole 2311 communicates with the pipe channel.

[0071] In this embodiment, as Figures 1 to 3 and Figure 6 shown, by providing the base mechanism 23, it is convenient to arrange both the cutting mechanism 21 and the hammering mechanism 22 on the base mechanism 23, so that the slitting device 2 is integrated into a whole, which is convenient for disassembly and assembly and also convenient for processing.

[0072] It can be understood that a fixing block is provided on the side of the fixed base 231 of the base mechanism 23 facing the bracket 1. The fixed base 231 is connected and fixed to the bracket 1 through the fixing block, so that the fixed base 231 is supported by the fixing block, that is, the fixed base 231 is arranged opposite to and spaced apart from the bracket 1 to form a space for the pipe 7 to pass through.

[0073] In this embodiment, in order to facilitate the cutter assembly 213 to cut the pipe 7 passing through the space, the fixed base 231 is provided with a through hole 2311 corresponding to the cutter assembly 213. It can be understood that the first driving member 211 drives the lifting platform 212 to drive the cutter assembly 213 to pass through the through hole 2311 and approach the bracket 1 to cut the pipe 7, so as to cut a notch on the pipe 7 for the first time.

[0074] It can be understood that by providing a plurality of limiting baffles 232 on the side of the fixed base 231 facing the bracket 1, the plurality of limiting baffles 232 are respectively located on opposite sides of the through hole 2311, and the plurality of limiting baffles 232 are arranged parallel to each other along the traveling direction of the pipe 7, that is, the limiting baffles 232 and the fixed base 231 enclose a pipe channel, and the through hole 2311 communicates with the pipe channel. In this way, when the pipe 7 enters the space between the fixed base 231 and the bracket 1, the pipe 7 can be further limited by the limiting baffles 232, so that the pipe 7 is located in the pipe channel and can be directly opposite to the through hole 2311, which not only improves the cutting accuracy and precision, but also effectively avoids the problem of the pipe 7 running off track.

[0075] In this embodiment, the fixed base 231 may be a plate-like structure, and the limiting baffle 232 may be a boss, a convex strip, a baffle or other structures, which are not limited here.

[0076] To ensure that the cutter assembly 213 accurately cuts the pipe 7, Figures 1 to 4 As shown, in one embodiment, the slitting device 2 also includes a guide mechanism 24 arranged on the fixed base 231, the guide mechanism 24 includes a guide shaft 241 and a linear bearing 242, the linear bearing 242 is arranged on the lifting platform 212, one end of the guide shaft 241 is connected to the side of the fixed base 231 facing the first driving member 211, and the other end of the guide shaft 241 is movably inserted into the linear bearing 242.

[0077] It can be understood that the linear bearing 242 is disposed on the lifting platform 212, that is, a mounting hole is disposed on the lifting platform 212, and the linear bearing 242 is disposed in the mounting hole, and the axial direction or extension direction of the guide shaft 241 is consistent with the moving direction of the lifting platform 212 driven by the first driving member 211. One end of the guide shaft 241 is fixedly connected to the fixed base 231, and the other end of the guide shaft 241 is movably provided in the linear bearing 242, so that the guide shaft 241 is slidably connected to the lifting platform 212 through the linear bearing 242.

[0078] In order to further improve the balance of the first driving member 211 driving the lifting platform 212 to move and ensure that the cutter assembly 213 accurately cuts the tube 7 , the guide mechanism 24 includes a plurality of guide mechanisms 24 disposed on the periphery of the lifting platform 212 .

[0079] In order to realize the automatic conveying and cutting of the pipe 7, in one embodiment, as Figure 1 and Figure 2 As shown, the pipe cutting device 100 further includes a conveying device 3, the bracket 1 has a feed end and a discharge end, and the conveying device 3 is used to pull the pipe 7 through the feed end, the pipe channel and the discharge end in sequence.

[0080] It can be understood that the conveying device 3 pulls the pipe 7 from the feed end to the discharge end so that the pipe 7 performs intermittent movement, and the first driving member 211 drives the cutter assembly 213 to pre-cut the pipe 7 so that the pipe 7 has a notch, and then the pipe 7 is pressed. At this time, the pipe 7 may not be completely cut off, and then the hammer block 222 is driven by the second driving member 221 to hammer the lifting platform 212, thereby driving the cutter assembly 213 to cut the pipe 7 for the second time, completing the entire cutting process. Through the secondary cutting, the cutting accuracy is high, the incision is smooth, and the pipe 7 is prevented from being not completely cut off or having burrs due to the first cutting, which is highly practical.

[0081] In one embodiment, if Figure 1 and Figure 2As shown, the conveying device 3 includes a first pressing wheel group 31. The first pressing wheel group 31 is arranged at the feeding end of the bracket 1, and the first pressing wheel group 31 is provided with an inlet for pulling the pipe 7 from the feeding end to the discharging end.

[0082] It can be understood that the first pressing wheel group 31 includes two first pressing wheels. The two first pressing wheels are arranged at the feeding end of the bracket 1, and the two first pressing wheels are arranged in parallel and at intervals, so that a material passing channel for the pipe 7 to pass through is formed between the two first pressing wheels. The first pressing wheel group 31 can pull the pipe 7 to enter from the feeding end. The pipe 7 extends into the gap between the two first pressing wheels, and under the drive of the two first pressing wheels, it is ensured that the pipe 7 moves smoothly on the material passing channel.

[0083] In one embodiment, as Figure 1 and Figure 2 shown, the conveying device 3 includes a second pressing wheel group 32. The second pressing wheel group 32 is arranged at the discharging end, and the second pressing wheel group 32 is provided with an outlet for pulling the pipe 7 from the feeding end to the discharging end.

[0084] It can be understood that the second pressing wheel group 32 includes two second pressing wheels. The two second pressing wheels are arranged at the discharging end of the bracket 1, and the two second pressing wheels are arranged in parallel and at intervals, so that a material passing channel for the pipe 7 to pass through is formed between the two second pressing wheels. The second pressing wheel group 32 can pull the pipe 7 to enter from the feeding end and output from the discharging end. The pipe 7 extends into the gap between the two second pressing wheels, and under the drive of the two second pressing wheels, it is ensured that the pipe 7 moves smoothly on the material passing channel. Optionally, in this embodiment, the first pressing wheel group 31 and the second pressing wheel group 32 move synchronously.

[0085] In this embodiment, in order to realize the synchronous movement of the first pressing wheel group 31 and the second pressing wheel group 32, a driving device can be arranged only on the second pressing wheel group 32, and the first pressing wheel group 31 is driven by the pipe 7. Of course, driving devices can also be arranged on both the first pressing wheel group 31 and the second pressing wheel group 32, and the two driving devices are set as synchronous driving devices, which is not limited here.

[0086] In one embodiment, as Figure 10 shown, the pipe cutting device 100 further includes a cutter plate 6. The cutter plate 6 is detachably embedded in the bracket 1 and is arranged opposite to the cutter assembly 213.

[0087] It can be understood that the cutter plate 6 is made of plastic material, and the cutter plate 6 can be circular, square, polygonal, etc., as long as it is ensured that the cutter plate 6 can abut against the cutter 2132 of the cutter assembly 213, so that the cutter 2132 will not be worn or damaged, and the service life of the cutter 2132 is improved.

[0088] In one embodiment, the cutter assembly 213 includes a cutter seat 2131 and a plurality of cutters 2132 , wherein the cutter seat 2131 is disposed on a side of the lifting platform 212 away from the first driving member 211 , and the plurality of cutters 2132 are disposed at intervals on a side of the cutter seat 2131 away from the lifting platform 212 .

[0089] In this embodiment, if Figure 4 and Figure 5 As shown, the knife seat 2131 is connected to the lifting platform 212, and the cutters 2132 are evenly arranged on the surface of the knife seat 2131 away from the hammer block 222. Optionally, the cutter 2132 can be designed as 1 blade, 2 blades, 3 blades, etc. according to the needs. Multiple blades are spaced and evenly arranged on the surface of the knife seat 2131 away from the hammer block 222.

[0090] In this embodiment, the cutter 2132 is evenly arranged on the cutter holder 2131 so that the marking tube is evenly divided, ensuring that with the assistance of the cutter holder 2131, the cutter 2132 can cut the tube 7 more stably.

[0091] Please refer to Figure 5 As shown, in one embodiment, the cutter assembly 213 further includes an elastic blocking member, which is disposed on a surface of the cutter seat 2131 away from the hammer block 222, and the cutter 2132 and the elastic blocking member are spaced apart.

[0092] It is understandable that the elastic resistance member may be foam. The elastic resistance member may be designed as one or more according to the requirements, and the elastic resistance member and the cutter 2132 are arranged at intervals. In this embodiment, by arranging the elastic resistance member, the cutter 2132 can resist the tube 7 when it moves down for cutting, so as to prevent the tube 7 from shifting during cutting, and can also prevent the cutter 2132 from driving the tube 7 to move upward during cutting, and can also play a certain buffering role. To ensure the cutting effect, optionally, the thickness of the elastic resistance member is greater than the length of the cutter 2132.

[0093] In one embodiment, the pipe cutting equipment 100 also includes a fiber optic sensing device 4, which includes an adjustment mechanism 42 and a sensing optical fiber 41. The adjustment mechanism 42 is disposed on the bracket 1, and the sensing optical fiber 41 is slidably connected to the adjustment mechanism 42 and is disposed adjacent to the pipe 7. The sensing optical fiber 41 is used to sense the position of the pipe 7; wherein the adjustment mechanism 42 is used to adjust the position of the sensing optical fiber 41.

[0094] In this embodiment, the optical fiber sensing device 4 uses a PLC control program to control the intermittent movement of the tube 7 driven by the conveying device 3. The distance of each movement is the distance between the circular holes on two adjacent tubes 7. The position of the optical fiber is adjusted by the adjustment mechanism 42 to sense whether the position of the circular hole is in place, so that the tube 7 reaches the cutting position of the cutter 2132, thereby ensuring the cutting accuracy of the marking tube.

[0095] In this embodiment, the optical fiber sensing device 4 is provided on the bracket 1 through the adjusting seat 421 of the adjusting mechanism 42. The sensing optical fiber 41 is movably connected to the optical fiber fixing bracket 423 through the adjusting mechanism 42. The sensing optical fiber 41 is disposed adjacent to the pipe 7 to sense the position of the marked pipe on the pipe 7.

[0096] Please refer to Figure 7 and Figure 8 As shown, in one embodiment, the adjusting mechanism 42 includes an adjusting seat 421, at least one slider 422, an optical fiber fixing bracket 423, a screw 424 and a knob 425. The adjusting seat 421 is provided on the bracket 1. At least one sliding groove 4211 is formed in the adjusting seat 421. At least part of the slider 422 is movably disposed in the sliding groove 4211. The optical fiber fixing bracket 423 is fixedly connected to the slider 422. One end of the screw 424 sequentially passes through the adjusting seat 421 and the slider 422 and is threadedly connected to the slider 422 and the adjusting seat 421. The knob 425 is connected to the other end of the screw 424. Wherein, rotating the knob 425 drives the screw 424 to rotate, so that the slider 422 drives the optical fiber fixing bracket 423 to move along the sliding groove 4211.

[0097] It can be understood that at least one sliding groove 4211 is formed in the adjusting seat 421, the sensing optical fiber 41 is fixed to the optical fiber fixing bracket 423, at least one slider 422 is provided on the adjusting mechanism 42, and at least one slider 422 is slidably connected to at least one sliding groove 4211. One end of the screw 424 is connected to the knob 425, and the other end sequentially passes through the adjusting seat 421 and the slider 422 and is threadedly connected to the slider 422 and the adjusting seat 421. The knob 425 drives the screw 424 to rotate, so that the slider 422 drives the optical fiber fixing bracket 423 to move along the sliding groove 4211 to adjust the relative position between the sensing optical fiber 41 and the pipe 7.

[0098] In this embodiment, the movement of the sensing optical fiber 41 can be realized by adjusting the adjusting knob 425, so that when the pipe 7 reaches below the cutter 2132, the cutter 2132 is just located at the central cutting position of the pipe 7, ensuring the accuracy of the cutting position of the pipe 7.

[0099] In one embodiment, the pipe cutting device 100 further includes a guiding and tensioning device 5. The guiding and tensioning device 5 is located at the feeding end of the bracket 1. The guiding and tensioning device 5 includes a roller fixing seat 51, a guiding roller 52 and two limiting blocks 521. Wherein, the roller fixing seat 51 is provided on the bracket 1. Two ends of the guiding roller 52 are respectively rotatably connected to the roller fixing seat 51. The two limiting blocks 521 are sleeved on the outer wall of the guiding roller 52 at intervals. At least one limiting block 521 is movably connected to the guiding roller 52 and can move close to or away from the other limiting block 521.

[0100] In this embodiment, as Figure 1 ,Figure 2 and Figure 9 As shown in Figure 9 , the guiding and tensioning device 5 is located between the feeding end and the discharging end and is used for drivingly abutting against the pipe 7. It can be understood that the guiding and tensioning device 5 can guide the transmission of the pipe 7 and make the pipe 7 have a certain tension to prevent the pipe 7 from slipping during movement.

[0101] Please refer to Figure 9 As shown in Figure 9 , in one embodiment, the guiding and tensioning device 5 includes two roller fixing seats 51, two limiting blocks 521 and a guiding roller 52. The two roller fixing seats 51 are spaced apart on the bracket 1 and are located between the feeding end and the slitting device 2.

[0102] It can be understood that both ends of the guiding roller 52 are rotatably connected to the two roller fixing seats 51 respectively. The two limiting blocks 521 are sleeved on the guiding roller 52, and at least one limiting block 521 can move close to or away from the other limiting block 521 to limit the pipe 7.

[0103] In this embodiment, both of the two limiting blocks 521 can move, or only one of them can move to adjust the distance between the two limiting blocks 521 according to the actual width of the pipe 7, so that the pipe 7 can be limited directly below the cutting tool 2132, preventing the pipe 7 from running off track and ensuring the cutting accuracy.

[0104] Please refer to Figure 9 As shown in Figure 9 , in one embodiment, the guiding and tensioning device 5 further includes a tensioning roller 53. Both ends of the tensioning roller 53 are rotatably connected to the roller fixing seats 51 respectively, and the tensioning roller 53 is arranged offset up and down from the guiding roller 52, so as to form a tensioning channel between the guiding roller 52 and the tensioning roller 53, and the tensioning channel is for the pipe 7 to pass through.

[0105] It can be understood that by arranging the tensioning roller 53 offset up and down from the guiding roller 52, a tensioning channel is formed between the guiding roller 52 and the tensioning roller 53. The pipe 7 extends into the tensioning channel and is in a tensioned state, so that the pipe 7 can have a certain tension to prevent the pipe 7 from slipping during movement.

[0106] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
