Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a fully protected three-chuck laser tube cutting device. Background Art

[0002] In modern manufacturing, laser cutting technology is widely used due to its high precision, high efficiency and high flexibility. As an advanced laser cutting equipment, the three-chuck laser cutting machine plays an important role in pipe processing and other fields.

[0003] With the increasing requirements for production safety and equipment stability, three-chuck laser cutting machines are facing a series of challenges. In the design of traditional three-chuck laser cutting machines, most of the research focuses on the degree of automation of laser cutting equipment, reducing the size of the equipment, and the flexibility of the chuck. There is often a lack of effective protection measures for the driving source of the motion mechanism in the laser equipment or the high-energy laser beam generated by the laser cutting component. Because the driving source of the motion mechanism is exposed, there is a risk of accidental touch by the operator during operation. At the same time, the laser cutting components in the laser cutting area will generate high-intensity laser beams and high-temperature radiation when working. Without proper protection, it is easy to pose a serious threat to the personal safety of the operator. For example, laser radiation may damage the operator's eyes and skin.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the Invention

[0035] The present invention provides a fully protected three-chuck laser tube cutting device. To clarify the objectives, technical solutions, and effects of the present invention, the present invention is further described below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit its scope.

[0036] See also Figure 1-Figure 2The present invention provides a fully protected three-chuck laser tube cutting equipment, comprising a side-hanging bed 1, a gantry 14 arranged on the side-hanging bed 1, a laser cutting component 2 that can reciprocate along the gantry 14 in the front-back and up-down directions, a first chuck structure 41, a second chuck structure 42 and a third chuck structure 43 that can reciprocate along the left-right direction of the side-hanging bed 1; the gantry 14 divides the side-hanging bed 1 into a feeding area and a receiving area, and a plurality of spaced mounting side seats 11 are provided in the feeding area, a centering follower mechanism 31 is provided on the mounting side seat 11, and a centering follower mechanism protection structure 32 is provided on the outside of the centering follower mechanism 31; a plurality of feeding components 5 corresponding to the centering follower mechanism 31 are also provided in the feeding area, and the front ends of the plurality of feeding components 5 are respectively fixedly connected to the corresponding mounting side seats 11, and the rear ends of the plurality of feeding components 5 are connected by a feeding connecting rod 55, The feeding assembly 5 is used to transport the pipe from its rear end to the front end; the centering follower mechanism 31 is used to lift the pipe located at the front end of the feeding assembly 5; a plurality of spaced reinforced side seats 12 are provided in the material receiving area, and a material receiving mechanism 7 fixedly connected to the side wall of the side-hanging bed 1 is provided between the reinforced side seats 12, and a plurality of material receiving assemblies 8 corresponding to the material receiving mechanism 7 are also provided in the material receiving area, and the front ends of the plurality of material receiving assemblies 8 are respectively fixed to the side walls of the side-hanging bed 1, and the rear ends of the plurality of material receiving assemblies 8 are connected by a material receiving connecting rod; the material receiving mechanism 7 is used to perform follow-up support and tilted feeding of the pipe located in the material receiving area to the front end of the material receiving assembly 8; the plurality of material receiving assemblies 8 are used to transport the pipe from its front end to the rear end; a support 13 is provided between the adjacent mounting side seats 11 and the reinforced side seats 12, and the front side of the gantry 14 is fixedly connected to the support 13; please refer to Figure 4-Figure 5 The support 13 and the gantry 14 are surrounded by a protective box 6, which is used to enclose the laser cutting assembly 2 inside. A material unloading area 611 for unloading pipes is provided in front of the protective box 6, and avoidance areas 612 for the second chuck structure 42 and the third chuck structure 43 to pass through are provided on the left and right sides of the protective box 6, respectively. Figure 1 A first chuck protection structure 44 is provided on the outside of the first chuck structure 41 , a second chuck protection structure is provided on the outside of the second chuck structure 42 , and a third chuck protection structure 46 is provided on the outside of the third chuck structure 43 .

[0037] In actual application, the crane arm is used to load the pipe to be cut to the rear end / upstream of the feeding assembly 5, and the feeding assembly 5 operates and gradually transports the pipes one by one to the front end / downstream, that is, it is located at the lifting position of multiple centering follower mechanisms 31. The pipe to be cut is lifted by the centering follower mechanism 31 to be coaxial with the first chuck structure 41 and the second chuck structure 42. The pipe will be clamped by the first chuck structure 41 and the second chuck structure 42 and pushed toward the laser cutting assembly 2 by the first chuck structure 41 to realize cutting feeding. Therefore, the avoidance area 612 is opened on the left and right sides of the protective box 6 to avoid the corresponding chuck structure, and the cut pipe will be clamped by the third chuck structure 43, and with the cooperation of the material receiving mechanism 7, follow-up support and auxiliary unloading are performed. Moreover, since the second chuck structure 42 can move relative to the laser cutting assembly 2, when there is residual material left in the pipe, the laser cutting head of the laser cutting assembly 2 is vertically downward, reducing the distance between the second chuck structure 42 and the laser cutting assembly 2, and then directly cutting the remaining pipe, thereby reducing the amount of residual material. The residual material / short material is discharged from the discharge area 611, and the discharge area 611 can be placed with a receiving box 76 for receiving the residual material / short material, without the need to transport it through the receiving assembly 8. At the same time, the discharge area 611 is also convenient for the operator to enter the interior of the protective box 6 from here during the non-operating hours of the laser pipe cutting machine. When discharge is required, the receiving mechanism 7 tilts the discharge and transfers the pipe to the front end / upstream of the multiple receiving assemblies 8 spaced apart in the discharge area. The receiving assembly 8 operates and transports the processed and cut pipes one by one towards their rear end / downstream, and discharge is achieved with the help of a crane or manual assistance.

[0038] The laser tube cutting equipment described above, by providing a centering follower mechanism protection structure 32, multiple chuck protection structures, and a protection box 6, encloses the centering follower mechanism 31, the corresponding chuck drive mechanism, the gantry 14, and the laser cutting assembly 2 within the corresponding structures. When the operator is located outside the protection structures and the protection box 6, the drive mechanisms can be effectively prevented from touching the operator, and the scattering and reflection of the laser during the cutting process can be effectively prevented, thereby preventing the laser from escaping and causing harm to the operator. In addition, by providing multiple feeding assemblies 5 corresponding to the centering follower mechanism 31 in the feeding area, the multiple feeding assemblies 5 are used to transport the pipes one by one to the lifting position of the centering follower mechanism 31; by providing a receiving mechanism 7 in the receiving area, the pipes are provided with follow-up support and auxiliary tilting for the cutting process or after cutting, and by using multiple receiving assemblies 8 to transport the pipes one by one to the unloading area 611, the degree of automation of the tube cutting equipment can be improved, and the operator can be kept away from the laser tube cutting equipment, further improving the safety performance of the equipment.

[0039] Specifically, the laser cutting assembly 2 uses various driving mechanisms to enable the laser cutting head to move back and forth in the front-back and up-down directions. The laser cutting assembly 2 cooperates with three chuck structures that can be pushed in the left-right direction to achieve multi-directional cutting of the pipe. The laser cutting assembly 2 and the laser cutting head are both existing technologies and will not be described here.

[0040] More specifically, the centering follower mechanism protection structure 32, the protection box 6, etc. are all made of sheet metal parts, and related components such as air source processing can be centrally installed thereon for easy adjustment.

[0041] See also Figure 3-Figure 5 In some embodiments, a front protective curtain 68 is provided on the operating side of the protective box 6, and the front protective curtain 68 is used to block the unloading area 611; side protective curtains 69 are provided on the left and right sides of the protective box 6, respectively, and the side protective curtains 69 are used to block the avoidance area 612. The protective box 6 cooperates with the front protective curtain 68 and the side protective curtains 69 to achieve all-round laser protection. Moreover, the front protective curtain 68 has a lower manufacturing cost than the protective door, and it is more convenient to enter and exit the protective box 6. Specifically, the front protective curtain 68 and the side protective curtain 69 are preferably black fire curtains. Black has a strong shielding ability against the light generated by the laser, and the fire curtains are made of fire-resistant materials to prevent the fire curtains from melting due to heat, thereby extending the service life of the fire curtains.

[0042] See also Figure 3 、 Figure 6 In some embodiments, the lower surface of the protective box 6 is provided with a first clip 63 and a second clip 64. The upper portions of the front protective curtain 68 and the upper portions of the side protective curtains 69 are clamped between the first clip 63 and the second clip 64 via fasteners (specifically, screws, bolts, and nuts). In actual use, the first clip 63, the second clip 64, and the front protective curtain 68 or the side protective curtain 69 are modularly designed. During assembly, this modular assembly can be simply installed in the corresponding position of the protective box 6. When the front protective curtain 68 or the side protective curtain 69 needs to be replaced, the corresponding locking members are removed and replaced with new ones, making assembly and disassembly convenient. Furthermore, the first clip 63 and the second clip 64 cooperate with the fasteners to clamp and secure the upper portions of the front protective curtain 68 and the side protective curtain 69. This connection ensures that the front protective curtain 68 and the side protective curtain 69 remain stably attached to the protective box 6 during use.

[0043] See also Figure 3 、 Figure 4In some embodiments, a viewing window 613 is provided in the front of the protective box 6, and a transparent window 614 is provided within the viewing window 613. During the laser cutting operation, the operator needs to observe the situation within the cutting area in real time to promptly understand the cutting progress, the status of the pipe cutting, and whether there are any abnormalities. The provision of the transparent window 614 enables the operator to clearly observe the operating conditions of the laser cutting assembly 2 and other components within the protective box 6 through the viewing window 613 while ensuring their own safety, ensuring smooth cutting operations while avoiding the risk of injury from direct exposure to laser radiation. Specifically, the transparent window 614 is preferably made of radiation-proof glass.

[0044] See also Figure 4 and Figure 5 In some embodiments, a baffle 65 is further provided between the side-mounted bed 1 and the gantry 14. The baffle 65 is located within the avoidance area 612, and the lower surface of the baffle 65 is fixedly connected to the upper surface of the support 13. In actual applications, the lower surface of one side of the gantry 14 is fixedly connected to the support 13, and the lower surface of the other side is fixedly connected to the side-mounted bed 1. Since there is a certain distance between the support 13 and the laser cutting assembly 2, a baffle 65 is provided. The baffle 65 cooperates with the protective box 6 to further reduce the escape of laser light in the cutting area. In order to further enhance the shielding effect of the baffle 65 on the laser, an arc-shaped groove is further provided on the upper portion of the baffle 65 to match the curvature of the lower portion of the second chuck structure 42 and the third chuck structure 43.

[0045] See also Figure 5 In some embodiments, the support 13 is a hollow structure, and an exhaust duct 66 is provided between the support 13 and the side-hanging bed 1. The exhaust duct 66 passes through the left and right sides of the support 13, as well as the front and rear sides of the side-hanging bed 1; the air inlet of the exhaust duct 66 is connected to the inner cavity of the protective box 6. The exhaust duct 66 is connected to the exhaust device. The above arrangement can quickly absorb the dust generated in the cutting area and protect the working environment. In addition, the dust generated adheres to the optical lens of the laser cutting head, which will reduce the transmittance of the lens, resulting in laser energy attenuation, poor cutting quality, and increased scrap rate. Therefore, quickly sucking away the dust can protect the laser cutting head and extend the service life of the laser cutting head. Moreover, the exhaust duct 66 is relatively short, which makes full use of the position of the side-hanging bed 1 and the support 13, and the design is more reasonable.

[0046] See also Figure 4In some embodiments, a shield 67 is provided on the side wall of the support 13 facing the cutting area. The shield 67 is used to house the air inlet of the exhaust pipe 66 within the shield 67. The shield 67 also has an exhaust hole 671. The shield 67 covers the air inlet of the exhaust pipe 66, effectively directing the smoke and exhaust gas generated during the laser cutting process toward the exhaust hole 671. Furthermore, the cutting area also involves the unloading area 611. Therefore, the shield 67 also prevents short pipes or scraps from falling and directly contacting the exhaust pipe 66, thereby damaging the exhaust pipe 66.

[0047] See also Figure 7 and Figure 8 In some embodiments, a distance measuring mechanism 411 is provided on the outside of the first chuck structure 41, and the distance measuring mechanism 411 is used to measure the distance from the left end of the pipe loaded to the centering follower mechanism 31; the side walls of the gantry 14 in the front and rear directions are respectively provided with a shooting sensor (not shown in the figure); the shooting sensor is used to cooperate with the distance measuring mechanism 411 to sense the position of the right end of the pipe loaded to the centering follower mechanism 31 and measure the length of the pipe to be cut; the first chuck protection structure 44 includes a first protective cover 441 for enclosing the first Y-axis side hanging plate 471, the first Y-axis side hanging plate driving mechanism 472, the first chuck driving mechanism and the distance measuring mechanism 411 therein; the first protective cover 441 is provided with an avoidance hole 442 on the side wall facing the laser cutting assembly 2 to avoid the distance measuring mechanism 411. In this embodiment, the first Y-axis side plate drive mechanism 472 can be driven by a motor, gear, and rack. The first chuck structure 41 is fixedly connected to the first Y-axis side plate 471, so that the first Y-axis side plate 471 can drive the first chuck structure 41 to move back and forth along the length of the side-hanging bed 1. In actual application, the pipe fed to the centering follower mechanism 31 needs to be driven by the first Y-axis side plate drive mechanism 472 to move the first chuck structure 41 toward the left end of the pipe. According to the program settings, after the first chuck structure 41 moves to the set position, the distance measuring mechanism 411 is used to extend to the right and touch the left end of the pipe to measure the distance from the first chuck structure 41 to the left end of the pipe, so that the first chuck structure 41 can be firmly clamped to the left end of the pipe to avoid the occurrence of empty clamping of the pipe. Specifically, the distance measuring mechanism 411 is a cylinder, a movable plate, and a stroke sensor. By extending the cylinder's output end, the movable plate extends from the avoidance hole 442, and the movable plate's travel is measured using a travel sensor. Once clamped by the first chuck structure 41, the pipe is pushed to the right until the right end of the pipe blocks the two beam sensors. The actual length of the pipe can be calculated through signal conversion, enabling precise cutting. The first chuck protection structure 44 encloses the first Y-axis side plate drive mechanism 472 and the first chuck drive mechanism, preventing exposure of the drive mechanisms.

[0048] See also Figure 9 and Figure 10 In some embodiments, the second chuck protection structure and the third chuck protection structure 46 each include a first protective cover 461 disposed around the second Y-axis side plate, the second Y-axis side plate drive mechanism / the third Y-axis side plate 473, and the third Y-axis side plate drive mechanism 474; a second protective cover 463 disposed around the second chuck drive mechanism / the third chuck drive mechanism; and a fixed cover 462 having two ends connected to the sidewalls of the first protective cover 461 and the second protective cover 463, respectively. The fixed cover 462 is configured to be fixedly connected to the outer wall of the second chuck structure 42 / the third chuck structure 43. In actual use, the first protective cover 461 encloses the second Y-axis side plate and the drive mechanism thereon, the third Y-axis side plate 473 and the drive mechanism thereon, and the second protective cover 463 encloses the drive mechanism of the second chuck / the third chuck, effectively preventing operators from coming into contact with the drive mechanisms, reducing the probability of safety accidents, and ensuring the personal safety of operators. Furthermore, foreign matter can be prevented from entering the drive mechanism and interfering with its operation, and the appearance of the laser tube cutting machine can be made neater and more aesthetically pleasing. The fixed cover 462 is provided to connect the first protective cover 461 and the second protective cover 463, so that the chuck protection structure forms a whole, which facilitates the installation and removal of the entire chuck protection structure from the laser tube cutting machine.

[0049] Specifically, the second Y-axis side hanging plate driving mechanism and the third Y-axis side hanging plate driving mechanism 474 can be driven by a motor, a gear and a rack, and the driving mechanism is an existing technology.

[0050] See also Figure 10 For more details, please refer to Figure 4 The second chuck structure 42 is provided with a set of four large rollers 431 arranged in the vertical and horizontal directions, and a set of four small rollers 432 arranged in the vertical and horizontal directions. Figure 9The third chuck structure 43 is provided with a group of four large rollers 431 arranged in the up, down, left and right directions, a group of two small rollers 432 arranged in the left and right directions, and a group of two clamps 433 arranged in the up and down directions. The chuck structure that cooperates with the clamps 433 and the rollers enables the third chuck structure 43 to be moved to the left side of the laser cutting assembly 2, that is, the three chuck structures clamp the pipe at the same time. Moreover, the multiple groups of roller groups are set so that the positions of the second chuck structure 42 and the third chuck structure 43 can remain unchanged, and the first chuck structure 41 can be used to push the pipe, and the sliding force provided by the roller group is used to provide avoidance for the advancement of the pipe. The combination of multiple groups of large rollers 431 and small rollers 432, as well as the clamps, enables the chuck structure to have a wide variety of clamping methods, which can adapt to pipe cutting in more application scenarios.

[0051] In some embodiments, a chuck protection plate is provided in the inner cavity of the middle portion of the second chuck structure 42 and the third chuck structure 43. The chuck protection plate is provided to protect the inner cavity of the chuck structure.

[0052] See also Figure 9 In some embodiments, the first protective cover 461 includes a first cover body 4611 and a first access panel 4612 detachably connected to the first cover body 4611 via bolts, screws, or other similar screws. The first cover body 4611 defines a first access opening that matches the shape of the first access panel 4612, and the first access panel 4612 covers the first access opening. The first protective cover 461 is made of sheet metal, and the first access opening facilitates access to the drive mechanism within the first protective cover 461 through the first access opening after the first access panel 4612 is removed.

[0053] See also Figure 9 In some embodiments, the second protective cover 463 includes a second cover body 4631 and a second access panel 4633 removably connected to the second cover body 4631 via bolts, screws, or other similar screws. The second cover body 4631 defines a second access opening that matches the shape of the second access panel 4633, and the second access panel 4633 covers the second access opening. Similarly, the second protective cover 463 is made of sheet metal. The second access opening in the second protective cover 463 facilitates access to the drive mechanism within the second protective cover 463 through the second access opening after removing the second access panel 4633.

[0054] See also Figure 9In some embodiments, the sidewalls and bottom of the second cover 4631 are provided with heat dissipation holes 4632. During device operation, the chuck drive mechanism generates heat. If this heat cannot be dissipated promptly, the internal temperature of the mechanism will rise. The heat dissipation holes 4632 provided on the sidewalls and bottom can form an effective heat dissipation channel, allowing heat to be dissipated to the external environment in a timely manner, allowing the chuck drive mechanism to operate continuously and stably within a suitable temperature range. In this embodiment, the bottom of the first cover 4611 is an open structure, so there is no need to provide additional heat dissipation holes 4632.

[0055] See also Figure 9 In some embodiments, the fixed cover 462 includes a first extension section 4621 fixed to the sidewall of the first protective cover 461, a second extension section 4623 fixed to the sidewall of the second protective cover 463, and an arcuate section 4622 connecting the first extension section 4621 and the second extension section 4623. The arcuate section 4622 has a curvature consistent with that of the second chuck structure 42 / third chuck structure 43. The lower surface of the arcuate section 4622 abuts against the outer peripheral wall of the upper portion of the second chuck structure 42 / third chuck structure 43, and the arcuate section 4622 is fixed to the second chuck structure 42 / third chuck structure 43. The fixed cover 462 is adapted to the shape of the second chuck structure 42 / third chuck structure 43. In practical applications, the first extension section 4621 and the second extension section 4623 can be designed with different lengths or arcuate sections 4622 with different curvatures to adapt the chuck protective structure to chuck structures with different curvature specifications. In addition, each part of the three-section fixed cover 462 is connected to other parts of the equipment, thereby ensuring that the chuck protection structure is firmly installed and easy to assemble, and the three parts of the fixed cover 462 can be distributed and fixed to the equipment.

[0056] See also Figure 7 and Figure 9In some embodiments, the outside of the first chuck protection structure 44, the second chuck protection structure and the third chuck protection structure 46 are all provided with a Y-axis drag chain fixing seat 464 that is connected to the first chuck protection structure 44 / the second chuck protection structure / the third chuck protection structure 46, and the Y-axis drag chain fixing seat 464 is used to be fixedly connected to the end of the Y-axis drag chain. The Y-axis drag chain is used to accommodate and protect various cables, air pipes and other pipelines so that they can follow the movement in an orderly manner during the movement of the equipment. The setting of the Y-axis drag chain fixing seat 464 provides a special fixed position for the Y-axis drag chain, ensuring that the Y-axis drag chain can be accurately located on the predetermined path when the equipment is running, avoiding the Y-axis drag chain from swinging randomly or interfering with other components, and making the wiring inside the equipment more standardized and neat. In addition, the Y-axis drag chain fixing seat 464 provides a clear position and connection method for the installation of the Y-axis drag chain. The operator only needs to fix the end of the Y-axis drag chain on the Y-axis drag chain fixing seat 464 to complete the installation. The operation is simple and convenient; it is also conducive to regular maintenance and replacement.

[0057] See also Figure 5 In some embodiments, the centering follower mechanism protection structure 32 includes a first protective plate 321 for being fixed to the corresponding mounting side seat 11, and a second protective plate 323 for being fixed to the front side wall of the side-hanging bed 1; a lap plate 322 is provided on the side wall of the first protective plate 321 facing the second protective plate 323, and the lap plate 322 and the inner side wall of the second protective plate 323 are fixed by bolts after abutting against each other; the first protective plate 321, the second protective plate 323 and the mounting side seat 11 and the side-hanging bed 1 form a space for installing the centering follower mechanism 31. In actual use, the centering follower mechanism 31 is located on the operating side of the side-mounted bed 11. By enclosing the centering follower mechanism 31 within the space enclosed by the first protective plate 321, the second protective plate 323, the mounting side seat 11, and the side-mounted bed 1, the operator is effectively prevented from accidentally contacting the centering follower mechanism 31. This effectively avoids the risk of injury to the operator, such as pinching or abrasions, caused by accidentally touching the centering follower mechanism 31 while it is in operation or at rest, thereby ensuring the operator's personal safety. In addition, when installing the first and second protective plates 321, 323, or when maintenance or repair of the centering follower mechanism 31 is required, the connection method of the lap plate 322 and bolts allows for relatively convenient removal and installation of the protective structure, speeding up removal and installation and reducing the difficulty and time cost of maintenance work.

[0058] Furthermore, the structure is open at the top and bottom, which makes it easy to observe the operation of the centering follower mechanism 31 from the outside and is beneficial to heat dissipation.

[0059] See also Figure 11In some embodiments, the plurality of feeding components 5 include a feeding frame 51, a feeding driving wheel 521 rotatably arranged on the feeding frame 51, a feeding driven wheel 522, and a feeding transport chain 523 wound around the feeding driving wheel 521 and the feeding driven wheel 522, and a plurality of feeding limiting blocks 524 are provided on the outer surface of the feeding transport chain 523, and a feeding storage bayonet is formed between two adjacent feeding limiting blocks 524. The feeding driving wheels 521 on the plurality of feeding components 5 are connected by a feeding transmission shaft 531, and the feeding transmission shaft 531 is connected by driving to the feeding rotation drive device 54; the outer cover of the feeding rotation drive device 54 is provided with a feeding protective cover body 56; the front end of the feeding frame 51 is provided with a feeding limit axis plate 514, and the feeding limit axis plate 514 is used to prevent the pipe from continuing to be transported forward. Specifically, multiple pipes are each confined within their respective feed and storage bayonet ports, which prevent displacement of the pipes and ensure consistent conveying speeds for each pipe. The synchronous operation of multiple feed and transport chains 523 is achieved using a feed rotation drive device 54 and a feed transmission shaft 531, resulting in a simple structure and a high synchronization rate. Furthermore, the feed drive wheel 521, the feed driven wheel 522, and the feed and transport chain 523 are conventional chain drive components. Assembling the feed limiter 524 on the feed and transport chain 523 forms the feed and storage bayonet port, which is simple to manufacture and inexpensive.

[0060] Specifically, the provision of the feed axis limiting plate 514 can prevent the pipe from sliding out / rolling out of the feed assembly 5 easily due to the inertia of the pipe moving forward. The feed axis limiting plate 514 is used to limit the movement of the pipe and improve safety.

[0061] More specifically, the feeding rotation drive device 54 is arranged away from the bed, which is the operating side. Therefore, the feeding rotation drive device 54 is covered by the feeding protective cover 56, which can be used to protect the operator on the operating side.

[0062] Each set of feeding components 5 in this embodiment adopts a detachable design, which occupies a small space and is convenient for shipment and transportation after disassembly.

[0063] See also Figure 11In some embodiments, the feeding frame 51 includes a feeding crossbeam 511 parallel to the conveying direction of the pipe, a first feeding vertical beam 512 fixed to the front of the feeding crossbeam 511, and a second feeding vertical beam 513 fixed to the rear of the feeding crossbeam 511; the adjacent second feeding vertical beams 513 are connected by the feeding connecting rod 55. Specifically, the feeding crossbeam 511, the first feeding vertical beam 512 and the second feeding vertical beam 513 are all square tubes, which are light in weight and easy to obtain. The front end of the feeding crossbeam 511 is fixed to the side-hanging bed 1, and the feeding connecting rod 55 is used to realize the fixing of multiple feeding crossbeams 511, so that the multiple feeding components 5 form a structure that is easy to disassemble and assemble, which is convenient for shipment and on-site installation.

[0064] See also Figure 13 In some embodiments, the feeding driving wheel 521 is sleeved on the feeding rotating shaft 5211, and the feeding rotating shaft 5211 is connected to the feeding beam 511 through two feeding belt seat bearings 5212, and one end of the feeding rotating shaft 5211 is connected to the feeding transmission shaft 531 through a feeding universal joint coupling 532; the feeding rotation driving device 54 includes a feeding motor bracket 541, a feeding driving motor 542 arranged on the feeding motor bracket 541, a feeding driving sprocket 543 arranged on the output end of the feeding driving motor 542, a feeding driven sprocket 544 sleeved on one of the feeding rotating shafts 5211, and a feeding driving chain 545 wound between the feeding driving sprocket 543 and the feeding driven sprocket 544. When transporting pipes, the feeding drive motor 542 drives the feeding active sprocket 543 to rotate, and under the transmission of the feeding drive chain 545 and the feeding driven sprocket 544, drives the feeding shaft 5211 to rotate, and then drives the feeding active wheel 521 on the feeding shaft 5211 to rotate, providing power for the feeding transport chain 523. In addition, when one of the feeding shafts 5211 rotates, the power is transmitted to the other feeding shaft 5211 through the feeding universal joint coupling 532, the feeding transmission shaft 531 and the feeding universal joint coupling 532, thereby realizing the synchronous rotation of multiple feeding transport chains 523.

[0065] See also Figure 12In some embodiments, the feed protection cover 56 includes a feed motor cover 561 and a feed transmission cover 563 communicating with the inner cavity of the feed motor cover 561; the feed motor bracket 541 and the feed drive motor 542 are housed within the feed motor cover 561; and the feed driving sprocket 543, the feed driven sprocket 544, and the feed drive chain 545 are housed within the feed transmission cover 563. Splitting the feed protection cover 56 into two major parts not only facilitates the preparation of sheet metal parts and reduces manufacturing difficulty, but also makes the shape of the feed protection cover 56 more compatible with the shape of the feed rotation drive device 54, reducing the space occupied by the feed rotation drive device 54.

[0066] See also Figure 12 In some embodiments, the feed motor housing 561 is provided with a feed inspection port, which is covered by a removable feed cover 562. With this arrangement, the feed cover 562 can be opened to expose the feed rotation drive device 54 for maintenance without having to disassemble the entire feed protective housing 56.

[0067] See also Figure 11 and Figure 12 , see Figure 2 In some embodiments, a feed guard plate 515 is provided at the rear end of the feed beam 511 to shield the rear end of the feed drive wheel 521. The rear end is the operating side, and the feed guard plate 515 can shield the feed drive wheel 521, thereby further preventing clothes or other items from being caught in it.

[0068] See also Figure 14 and Figure 15 In some embodiments, the material receiving mechanism 7 includes a base 71, a movable plate 72 movably mounted on the base 71, a lifting drive 73 for driving the movable plate 72 upward or downward, a receiving plate 74 having one end surface rotatably connected to the upper portion of the movable plate 72, and a receiving drive 75 fixed to the movable plate 72 for driving the receiving plate 74 to tilt horizontally or downwardly. The lifting drive 73 drives the movable plate 72 to move upward and downward with the pipe, thereby varying the height of the receiving plate 74 relative to the pipe (especially for non-round pipes). When supporting the pipe, the receiving drive 75 drives the receiving plate 74 to a horizontal position, and then the movable plate 72 and the receiving plate 74 move vertically. When unloading the pipe, the receiving drive 75 drives the receiving plate 74 to tilt, thereby guiding the pipe placed on the receiving plate 74 to the front end of the material receiving assembly 8.

[0069] See also Figure 14 and Figure 15In some embodiments, the material receiving mechanism 7 further includes a lower protective cover 77, an upper protective plate 78, and side protective plates 79. The lower protective cover 77 is located below the material receiving plate 74 and is used to house the movable plate 72, the lifting drive member 73, and the material receiving drive member 75. The upper protective plate 78 is fixedly connected to the movable plate 72 and is located above the base 71. The side protective plates 79 are located on the outside of the lower protective cover 77 near the side protective plates 79. The lower protective cover 77 and the upper protective plate 78 cooperate with the material receiving plate 74 to isolate the laser to the greatest extent, thereby protecting the material receiving mechanism 7 from damage by the laser when the laser tube cutting equipment is performing cutting operations. In order to provide a downward-sloping avoidance space for the material receiving plate 74, so that there is a gap between the side plates and the material receiving plate 74, the side protective plates 79 are provided to further block the laser generated by the laser cutting assembly 2, thereby further improving the protection effect.

[0070] See also Figure 14 In some embodiments, the width of the lower protective cover 77 is smaller than the width of the receiving plate 74, and the length of the lower protective cover 77 is smaller than the length of the receiving plate 74. In other words, the overall size of the lower protective cover 77 is smaller than the size of the receiving plate 74, so that the receiving plate 74 can completely cover the upper part of the lower protective cover 77, thereby ensuring that the movable plate 72, the lifting drive member 73, the receiving drive member 75 and other components inside the lower protective cover 77 are not affected by the laser.

[0071] See also Figure 14 In some embodiments, the rear side of the side guard plate 79 is provided with an outwardly bent avoidance plate 791. The avoidance plate 791 is used to avoid the side wall of the upper guard plate 78 located behind it. As mentioned above, the material receiving plate 74 can tilt downward. Therefore, when the material receiving plate 74 tilts downward, it will simultaneously cause the side guard plate 79 to tilt. Therefore, in order to prevent the side guard plate 79 from contacting the outer wall of the upper guard plate 78, the outwardly bent avoidance plate 791 is provided.

[0072] See also Figure 15In some embodiments, the lifting drive member 73 includes a lifting drive motor 731, a transmission gear 732 connected to the output end of the lifting drive motor 731, and a transmission rack 733 disposed on the front side of the base 71. The output end of the lifting drive motor 731 passes through the front and rear side walls of the movable plate 72. The transmission rack 733 extends vertically on the base 71. The transmission gear 732 meshes with the transmission rack 733. During use, when the lifting drive motor 731 rotates forward, it drives the transmission gear 732 to rotate forward. Under the guidance of the transmission rack 733, the movable plate 72 and the receiving plate 74 are synchronously raised. Conversely, when the lifting drive motor 731 rotates reversely, it drives the transmission gear 732 to rotate reversely, causing the movable plate 72 and the receiving plate 74 to descend synchronously. The above structure has high transmission efficiency and high transmission precision.

[0073] Specifically, the lifting drive motor 731 is a servo motor, which has a brake function, which can prevent the pipe from falling and causing safety hazards due to a sudden power outage of the lifting drive motor 731 when cutting, supporting or connecting the pipe.

[0074] See also Figure 15 In some embodiments, the material receiving drive member 75 is a tilted material receiving cylinder.

[0075] In some embodiments, the plurality of material receiving components 8 include a material receiving frame, a material receiving active wheel rotatably arranged on the material receiving frame, a material receiving driven wheel, and a material receiving transport chain wound between the material receiving active wheel and the material receiving driven wheel, a plurality of material receiving limiting blocks are arranged on the outer side of the material receiving transport chain, and a material receiving storage bayonet is formed between two adjacent material receiving limiting blocks, the material receiving active wheels on the plurality of material receiving components 8 are connected by a material receiving transmission shaft, and the material receiving transmission shaft is connected to the material receiving rotation drive device; the outer cover of the material receiving rotation drive device is provided with a material receiving protective cover body; the rear end of the material receiving frame is provided with a material receiving limit shaft plate 81, and the material receiving limit shaft plate 81 is used to prevent the pipe from continuing to be transported to the rear. Please refer to Figure 1 As can be seen from the above description, the material receiving assembly 8 and the material feeding assembly 5 are essentially identical in structure, differing primarily in that, based on the conveying inertia of the pipe, the material receiving axis limit plate 81 is positioned downstream, while the material feeding axis limit plate 514 is positioned upstream. Furthermore, the front end of the material feeding frame 51 is fixedly connected to the mounting side seat 11, while the front end of the material receiving frame is fixedly connected to the side wall of the side-mounted bed 1. The material feeding assembly 5 and the material receiving assembly 8 utilize essentially the same structure, with one for feeding and the other for receiving. This further simplifies the complexity of the pipe cutting equipment and reduces manufacturing costs.

[0076] See also Figure 16In some embodiments, a travel sensing mechanism 82 for sensing the pipe is further provided in front of the receiving limit axis plate 81. The travel sensing mechanism 82 comprises a support plate 821 fixed to the side wall of the receiving frame, a travel switch 822 disposed on the support plate 821, and a material arrival pressure plate 823 disposed at the output end of the travel switch 822. The travel sensing mechanism 82 is provided to automatically detect whether the pipe has been transported to the set position. When the pipe triggers the travel sensing mechanism 82, it indicates that the pipe has been transported to the designated position. At this time, the travel sensing mechanism 82 feeds back a signal to the control system, which controls the receiving rotation drive device to stop until the pipe is unloaded. At this time, the receiving rotation drive device restarts to automatically receive and transport the next pipe. Specifically, when the pipe is conveyed to the position of the material receiving pressure plate 823, the material receiving pressure plate 823 is pressed down, triggering the travel switch 822, and the control system controls the material receiving rotation drive device to stop the conveyance of the pipe. After the pipe is unloaded and transferred to the position away from the material receiving frame, the material receiving rotation drive device will start again. The above-mentioned setting cooperates with the material receiving mechanism 7 to realize fully automatic material receiving and feeding.

[0077] See also Figure 16 In some embodiments, a photoelectric sensor 831 is further provided upstream of the material receiving pressure plate 823 (the figure indicates a mounting plate for the photoelectric sensor 831). The material receiving and transporting chain is affixed with a plurality of sensing plates 832 corresponding to the material receiving and storage openings. The photoelectric sensor 831 is configured to sense the sensing plates 832. When the sensing plates 832 pass the position of the photoelectric sensor 831, the material receiving and transporting chain pauses. The material receiving and transporting chain will not transfer the next pipe until the pipe at the downstream end of the material receiving and transporting chain has been unloaded. The material receiving mechanism 7 will then transfer the next pipe to the upstream end of the material receiving and transporting chain.

[0078] In summary, the present invention, through the provision of a centering follower mechanism protection structure 32, multiple chuck protection structures, and a protection box 6, encloses the centering follower mechanism 31, the corresponding chuck drive mechanism, the gantry 14, and the laser cutting assembly 2 within the corresponding structure. When the operator is located outside the protection structures and the protection box 6, the drive mechanisms can be effectively prevented from touching the operator, and the scattering and reflection of the laser during the cutting process can be effectively prevented, thereby preventing the laser from escaping and causing harm to the operator. In addition, by providing multiple feeding assemblies 5 corresponding to the centering follower mechanism 31 in the feeding area, the multiple feeding assemblies 5 are used to transport the pipes one by one to the lifting position of the centering follower mechanism 31; by providing a receiving mechanism 7 in the receiving area, the pipes during or after cutting are provided with follow-up support and auxiliary tilting for unloading, and by using multiple receiving assemblies 8 to transport the pipes one by one to the unloading area 611, the degree of automation of the pipe cutting equipment can be improved, and the operator can be kept away from the laser pipe cutting equipment, further improving the safety performance of the equipment.
