[0002] The current protective measures for chuck-type laser cutting machines can be achieved by setting a protective box on the outside of the laser cutting head, or by setting an external protective cover structure on each chuck and the drive mechanism that drives the corresponding chuck to protect the components in the chuck and the drive mechanism.

[0039] The present invention provides an enclosed beveling pipe cutting device. To make the objectives, technical solutions, and effects of the present invention more clearly understood, the present invention is further described in detail 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 the scope of protection of the present invention.

[0040] See also Figure 2 The present invention provides an enclosed bevel pipe cutting device, comprising a bed 1, a gantry 12 arranged on the bed 1, a first chuck structure 31, a second chuck structure 32 and a third chuck structure 33 that can reciprocate along the Y axis of the bed 1; the enclosed bevel pipe cutting device also includes a laser cutting component 2 arranged on the gantry 12 and capable of displacement along the X axis, Z axis and A axis of the bed 1, a plurality of spaced mounting side seats 11 arranged on one side of the gantry 12 and fixed to the bed 1, a feeding and conveying component 5 and a loading mechanism 41 arranged on the mounting side seat 11, a plurality of spaced mounting receiving mechanisms 42 arranged on the other side of the gantry 12 and fixed to the bed 1, and a plurality of spaced mounting side seats 11 arranged on the mounting side seat 11. The material receiving and conveying assembly 602 downstream of the material receiving mechanism 42, and the short material conveying assembly 601 arranged next to the material receiving and conveying assembly 602 near the gantry 12; the feeding and conveying assembly 5 is used to convey the pipe toward the loading mechanism 41; the loading mechanism 41 is used to lift the pipe located downstream of the feeding and conveying assembly 5, and is used to support the pipe during the processing; the material receiving mechanism 42 is used to support the pipe during the processing, and is used to tilt the processed pipe to the upstream of the material receiving and conveying assembly 602 or the short material conveying assembly 601; the short material conveying assembly 601 is used to convey the short material from upstream to downstream; please refer to Figure 1The enclosed bevel pipe cutting equipment further includes a first outer enclosing structure 7 for enclosing the bed 1, the loading mechanism 41 and the downstream of the feeding and conveying assembly 5, a protective box 8 for enclosing the gantry 12 and the laser cutting assembly 2, and a second outer enclosing structure 9 for enclosing the material receiving mechanism 42; the inner cavities of the first outer enclosing structure 7, the protective box 8 and the second outer enclosing structure 9 are interconnected; refer to Figure 3 The first outer enclosure structure 7 is provided with a loading port 78 on the side wall facing the operation side, and the loading port 78 is used for loading pipes; please refer to Figure 4 A feeding port 91 is provided on the side wall of the protective box body 8 and the operating side of the second outer enclosure structure 9, and the feeding port 91 is used for feeding pipes.

[0041] In actual application, the pipe is transferred to the upstream position of the feeding and conveying assembly 5 by a crane or a forklift, and the loading is simply assisted by manual labor. When the pipe is gradually transported downstream through the feeding and conveying assembly 5, the pipe is transported to the interior of the first outer enclosure structure 7 through the loading port 78 of the first outer enclosure structure 7. Specifically, an induction switch is provided on the feeding and conveying assembly 5. When the pipe is delivered to the position, it will trigger the induction switch, and the control mechanism drives the loading mechanism 41 to lift the pipe to be coaxial with the first chuck structure 31, the second chuck structure 32 and the third chuck structure 33, so that the first chuck structure 31 and the second chuck structure 32 can clamp the pipe. Then the first chuck structure 31 and the second chuck structure 32 push the pipe toward the direction of the laser cutting assembly 2, so that the laser cutting assembly 2 can process and cut the pipe. After one end of the pipe moves to the other side of the gantry 12, its end is clamped by the third chuck structure 33, and the pipe is supported by the receiving mechanism 42. Under the action of the feeding mechanism 41 and the receiving mechanism 42, the middle part of the pipe is ensured not to fall, thereby ensuring the processing accuracy of the pipe. When the pipe is cut and needs to be unloaded, the material receiving plate on the material receiving mechanism 42 tilts downward, allowing the pipe to pass through the unloading port 91 on the second outer enclosure structure 9 and roll down to the upstream of the material receiving and conveying assembly 602. For the unloading of short materials, the short materials roll down to the upstream of the short material conveying assembly 601. The control mechanism drives the short material conveying assembly 601 to operate, thereby transporting the pipe located upstream in the downstream direction. When the material receiving mechanism 42 continues to unload the pipe, the pipe on the short material conveying assembly 601 can be continuously transported downstream, realizing automatic unloading and conveying of short materials. In addition, due to the addition of the first outer enclosure structure 7 and the second outer enclosure structure 9 on the outside of the bed 1, combined with the protective box 8, the laser processing process of the pipe is in a relatively sealed environment, which can isolate the operation of the driving components such as the first chuck structure 31, the second chuck structure 32, the third chuck structure 33, and the laser cutting assembly 2 from external dust, so that the pipe processing process is in a clean working environment, thereby improving the service life of the equipment and improving the overall aesthetics of the equipment. Furthermore, the laser cutting assembly 2 can realize multi-axis motion and can perform straight pipe cutting or bevel cutting on the pipe to meet the processing requirements of the pipe.

[0042] Specifically, the feeding mechanism 41 and the receiving mechanism 42 are prior art and will not be described in detail here.

[0043] Compared with the prior art, the above-mentioned enclosed bevel pipe cutting equipment has a first outer enclosing structure 7 and a second outer enclosing structure 9 added to the outside of the bed 1, which are combined with the protective box 8, so that the laser processing process of the pipe is in a relatively sealed environment, and can isolate external dust from the operation of driving components such as the first chuck structure 31, the second chuck structure 32, the third chuck structure 33, and the laser cutting assembly 2, so that the pipe processing process is in a clean working environment, thereby improving the service life of the equipment and improving the overall aesthetics of the equipment.

[0044] See also Figure 3 Specifically, each of the first, second, and third chuck structures 31, 32, and 33 is provided with a protective cover 34. The protective cover 34 serves to enclose the drive components (e.g., motors, gears, etc.) that drive the chuck structures along the Y-axis of the bed 1. Laser cutting inevitably generates dust and iron filings, and the protective cover enhances this protection.

[0045] See also Figure 3 and Figure 4 In some embodiments, the first outer enclosure structure 7 includes a plurality of first 7-shaped frames 71 whose bottoms are fixedly connected to the rear sidewall of the bed 1 and arranged parallel to the Y-axis of the bed 1, a first rear guard plate 72, a first upper guard plate 73, and a first front guard plate 74 respectively fixed to the corresponding first 7-shaped frames 71; the loading port 78 is located between the first front guard plate 74 and the first upper guard plate 73; and the lower surfaces of the plurality of first upper guard plates 73 are each provided with a detachable first protective curtain (not shown in the figure), each of which is used to cover the corresponding loading port 78. The opening of the loading port 78 facilitates the transportation of pipes under the action of the feeding and conveying assembly 5, allowing the pipes to smoothly enter the interior of the first outer enclosure structure 7. Specifically, the first front guard plate 74 is provided with a plurality of avoidance holes 741 for the feeding rack of the feeding and conveying assembly 5 to pass through, thereby reducing the size of the loading port 78 and increasing the height of the first front guard plate 74, thereby improving the sealing performance of the first outer enclosure structure 7. The first protective curtain is soft and inexpensive compared to a flip door. It also does not hinder the passage of pipes into the first outer enclosure 7 and further enhances the sealing performance of the first outer enclosure 7. The sheet metal structure formed by the first 7-shaped frame 71, the first rear guard plate 72, the first upper guard plate 73, and the first front guard plate 74 provides a certain level of structural rigidity and is cost-effective to manufacture. Furthermore, to enhance the structural rigidity of the first outer enclosure 7, it includes multiple reinforcing ribs.

[0046] See also Figure 3 and Figure 4In some embodiments, each of the first upper guard plates 73 includes a first fixed plate 731 whose lower surface is fixedly connected to the corresponding first 7-shaped frame 71, and an inverted L-shaped first flip door 732 hingedly connected to the front end of the corresponding first fixed plate 731. A first hydraulic support rod 75 is provided on the outer wall of the first 7-shaped frame 71. The first hydraulic support rod 75 is used to swing the corresponding first flip door 732 upward around the front end of the corresponding first fixed plate 731. When debugging or maintenance is required for the internal mechanisms of the first outer enclosure 7 (e.g., the loading mechanism 41, the downstream portion of the feed conveyor assembly 5, etc.), the first hydraulic support rod 75 can be used to open the corresponding first flip door 732, allowing operators / maintenance personnel to enter and inspect the equipment's operation.

[0047] See also Figure 3 and Figure 4 In some embodiments, the outer walls of the multiple first 7-shaped frames 71 are further provided with first sensing switches 76 . These first sensing switches 76 are each used to detect whether the corresponding first flip door 732 is closed. Because both the loading and unloading areas are relatively large, multiple first flip doors 732 are provided. The provision of the first sensing switches 76 ensures that the first flip doors 732 are closed, thereby preventing a reduction in the sealing of the first outer enclosure structure 7 . Specifically, the first sensing switches 76 are electrically connected to the control mechanism, and can be programmed to disable the device when any of the first flip doors 732 is open. This prevents personnel from entering the device and other personnel from operating the device unknowingly, thereby improving device safety.

[0048] See also Figure 1 In some embodiments, the second outer enclosure structure 9 includes multiple second 7-shaped frames fixed to the rear sidewall of the bottom bed 1 and arranged parallel to the Y-axis of the bed 1, and second rear guard plates and second upper guard plates fixed to corresponding second 7-shaped frames. The material discharge opening 91 is located below the corresponding second upper guard plates. The lower surfaces of the multiple second upper guard plates are each provided with a removable second protective curtain (not shown), each of which is used to cover the corresponding material discharge opening 91. Since the short material conveying assembly 601 and the receiving material conveying assembly 602 are close to the ground, there is no need for a front guard plate; the second protective curtains are sufficient to shield the material discharge opening 91.

[0049] See also Figure 1 and Figure 4In some embodiments, each of the plurality of second upper guard plates includes a second fixed plate whose lower surface is fixedly connected to the corresponding second 7-shaped frame, and a second flip door hinged to the front end of the corresponding second fixed plate and in an inverted L-shape. Second hydraulic struts are provided on the outer walls of the second 7-shaped frame, configured to cause the corresponding second flip door to flip upward around the front end of the corresponding second fixed plate. Second sensor switches are also provided on the outer walls of the plurality of second 7-shaped frames, each configured to detect whether the corresponding second flip door is fully closed. As can be seen from the above description, the overall construction of the first outer enclosure structure 7 and the second outer enclosure structure 9 is substantially identical, i.e., the first flip door 732 and the second flip door are opened and closed in the same manner. This arrangement reduces the complexity of opening and closing the flip door for operators / maintenance personnel.

[0050] See also Figure 4 In some embodiments, a lighting lamp 77 is further provided inside the first outer enclosure structure 7 and the second outer enclosure structure 9. Specifically, the provision of the lighting lamp 77 illuminates the internal mechanisms of the first outer enclosure structure 7 and the second outer enclosure structure 9, which are relatively dark inside, to facilitate debugging and maintenance by maintenance personnel.

[0051] See also Figure 2 and Figure 4 In some embodiments, the bed 1 is formed by stacking and fixing a plurality of transverse tubes, and an exhaust dust removal port 101 is provided on any of the transverse tubes, and the exhaust dust removal port 101 is located between the gantry 12 and the short material conveying assembly 601; a dust hood 13 is provided below the laser cutting assembly 2; the dust hood 13 and the exhaust dust removal port 101 are connected by an exhaust dust removal pipe. Specifically, the rear end of the first 7-shaped frame 71 is fixed to the transverse tube. The corresponding length can be selected according to the length of the bed 1 or transverse tubes of different lengths can be spliced ​​together, which is convenient for material acquisition. Through the provision of the dust hood 13 and the exhaust dust removal pipe, the cutting area of ​​the protective box 8 has the function of exhausting dust, preventing the harmful gases and dust generated during pipe cutting from affecting the health of the operator, reducing the impact on the environment, and preventing the generated harmful gases and dust from escaping to the first outer enclosure structure 7 and the second outer enclosure structure 9.

[0052] See also Figure 4 In some embodiments, a detachable third protective curtain (not shown) is provided on the sidewall of the protective box 8 facing the operating side. The third protective curtain is used to cover the discharge opening 91. Specifically, the short material conveying assembly 601 is located in the discharge opening 91 of the protective box 8. The function of the third protective curtain is the same as that of the first and second protective curtains, and is also used to improve the sealing performance of the protective box 8.

[0053] Specifically, the third protective curtain is preferably a black fire curtain. Black has a strong shielding ability for the light generated by the laser, and the fire curtain is made of fireproof material, which can prevent the fire curtain from melting due to heat, thereby extending the service life of the fire curtain.

[0054] See also Figure 1 In some embodiments, the side wall of the protective box 8 facing the operating side is provided with a first inspection door 81; when processing the pipe, the first inspection door 81 is closed to protect the operator from the influence of the laser; when the laser cutting assembly 2 needs to be maintained, the first inspection door 81 is opened to facilitate personnel to enter the interior of the protective box 8 to protect personal safety. Figure 4 The first outer enclosure structure 7 and the second outer enclosure structure 9 are further provided with a second inspection door 92 on the side walls at the ends. When the loading area / unloading area needs to be inspected, the interior of the equipment can be entered through the second inspection doors 92 at both ends.

[0055] See also Figure 5 In some embodiments, the short material conveying assembly 601 includes a base frame 61, a short material driving wheel 621 rotatably and symmetrically disposed on the base frame 61, a short material driven wheel 622, and a short material chain 63 wound between the short material driving wheel 621 and the short material driven wheel 622. A plurality of short material receiving plates 64 spaced apart and extending perpendicular to the pipe conveying direction are disposed between the two short material chains 63. The short material driving wheel 621 is connected to a short material drive mechanism 66 via a short material transmission shaft 65. The short material drive mechanism 66 is used to drive the short material chain 63 and the short material receiving plates 64 to rotate, thereby conveying the pipe on the short material receiving plate 64 located upstream to the downstream. In the prior art, the collection of short materials / tail materials is achieved through a receiving hopper, which does not enable automatic collection of short materials / tail materials. By setting up the short material driving mechanism 66, utilizing the short material transmission shaft 65 and through the setting of the short material active wheel 621 and the short material driven wheel 622, the short material chain 63 is driven to rotate while the short material receiving plate 64 is displaced, so that the pipes on the upstream short material receiving plate 64 can be continuously transported downstream, cooperating with the receiving mechanism 42 to realize automatic receiving and conveying of the short materials.

[0056] See also Figure 5In some embodiments, the base frame 61 includes two symmetrically arranged short-stock side panels 611 parallel to the pipe conveying direction, and a plurality of connecting beams 612 for connecting the two short-stock side panels 611. A first notch is defined upstream of the two short-stock side panels 611, and the short-stock driven pulleys 622 are rotatably disposed in the corresponding first notch. The two short-stock driven pulleys 622 are connected by a driven rod 623. A second notch is also defined downstream of the two short-stock side panels 611, and the short-stock driving pulleys 621 are rotatably disposed in the corresponding second notch. The short-stock transmission shaft 65 is used to connect the two short-stock driving pulleys 621. The short-stock drive mechanism 66 is disposed adjacent to the material receiving and conveying assembly 602. The short-stock side panels 611 are lightweight compared to steel beams. The connecting beams 612 connect the two short-stock side panels 611 to improve the structural rigidity of the base frame 61. Bearing blocks are located in both the first and second slots, enabling the driven rod 623 and the stub drive shaft 65 to rotate relative to the base frame 61. These blocks also help maintain synchronization between the two stub chains 63. The area between the stub conveyor assembly 601 and the gantry 12 serves as the cutting area. Positioning the stub drive mechanism 66 away from the cutting area prevents the high-energy laser light from the laser cutting assembly 2 from damaging the transmission components within the stub drive mechanism 66.

[0057] See also Figure 5 and Figure 6 In some embodiments, the short material chain 63 includes a plurality of chain links 631 that rotate relative to one another, and inverted L-shaped support plates 632 disposed inside corresponding chain links 631. The ends of the plurality of short material splicing plates 64 are respectively fixedly attached to the upper surfaces of the corresponding inverted L-shaped support plates 632. The conveyor belt-like structure formed by the short material splicing plates 64 has greater structural rigidity and can withstand the impact of heavy / large short materials without deformation. Furthermore, when a corresponding short material splicing plate 64 needs to be replaced, it can be removed from the inverted L-shaped support plate 632 and replaced with a new one. This facilitates subsequent maintenance and is more cost-effective than replacing the entire conveyor belt.

[0058] See also Figure 5 In some embodiments, the two short-piece side plates 611 are each further secured with an inverted L-shaped guard plate 614, which serves to enclose the short-piece chain 63. The inverted L-shaped guard plates 614 prevent direct contact or impact between the pipe and the short-piece chain 63, thereby extending the service life of the short-piece chain 63 and reducing the frequency of maintenance required.

[0059] See also Figure 5In some embodiments, a limit beam 615 is further fixed to the upper surface of the inverted L-shaped guard plate 614 near the gantry 12. The provision of the limit beam 615 can prevent the pipe from sliding off the short material receiving plate 64, protecting the safety of the staff located next to the short material conveying assembly 601.

[0060] See also Figure 6 In some embodiments, the stub drive mechanism 66 includes a stub motor bracket 661, a stub drive motor 662 mounted on the stub motor bracket 661, a stub driving sprocket 663 mounted on the output end of the stub drive motor 662, a stub driven sprocket 664 sleeved on the stub transmission shaft 65, and a stub drive chain 665 wound between the stub driving sprocket 663 and the stub driven sprocket 664. During pipe transportation, the stub drive motor 662 rotates the stub driving sprocket 663. Driven by the stub drive chain 665 and the stub driven sprocket 664, the stub transmission shaft 65 is driven to rotate, which in turn drives the stub driving pulley 621 on the stub transmission shaft 65 to rotate, providing power for the stub chain 63.

[0061] See also Figure 1 In some embodiments, the short material driving mechanism 66 is further covered with a short material protection cover 616. The short material protection cover 616 can protect the short material driving mechanism 66 from external impact, thereby protecting the short material driving mechanism 66.

[0062] See also Figure 7In some embodiments, the plurality of material receiving and conveying components 602 include a frame 68, a material receiving active wheel 681 rotatably arranged on the frame 68, a material receiving driven wheel 682, and a material receiving chain 683 wound between the material receiving active wheel 681 and the material receiving driven wheel 682, and a plurality of material receiving limiting blocks 684 are arranged on the outer surface of the material receiving chain 683, and a material receiving and storage bayonet is formed between two adjacent material receiving limiting blocks 684, and the material receiving active wheels 681 on the plurality of material receiving and conveying components 602 are connected by a material receiving transmission shaft 685, and the material receiving transmission shaft 685 is connected to the material receiving drive mechanism 69, and the material receiving drive mechanism 69 is used to drive the material receiving chain 683 and the pipes in the material receiving and storage bayonet to be transported in the downstream direction. Since the material receiving and storage bayonet provided on the material receiving chain 683 can be used to restrict the movement of the pipe, as the pipe is unloaded, under the action of the material receiving drive mechanism 69, the short material driving wheel 621 and the short material driven wheel 622 are used to rotate the material receiving chain 683 from the upstream direction to the downstream direction, thereby transporting the pipes on each material receiving and storage bayonet one by one in the downstream direction. When the pipe is transported to the downstream end, the pipe on the material receiving and storage bayonet is unloaded, and the pipe can be transported out of the storage area, thereby achieving continuous operation. Similarly, an induction switch is also provided on the frame 68. When the pipe triggers the induction switch, the material receiving mechanism 42 will transport the pipe to the material receiving and conveying assembly 602, thereby achieving automatic material receiving.

[0063] See also Figure 1 In some embodiments, the outside of the material receiving drive mechanism 69 is further covered with a material receiving protective cover 691.

[0064] See also Figure 8 In some embodiments, the feeding conveying assembly 5 includes a feeding rack, a feeding driving wheel 521 rotatably arranged on the feeding rack, a feeding driven wheel 522, and a feeding chain 523 wound between 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 chain 523, and a feeding storage bayonet is formed between two adjacent feeding limiting blocks 524. The plurality of feeding driving wheels 521 on the feeding conveying assembly 5 are connected by a feeding transmission shaft 531, and the feeding transmission shaft 531 is in transmission connection with the feeding driving mechanism 54; the feeding driving mechanism 54 is arranged downstream of the feeding rack; the plurality of feeding transmission shafts 531 are connected by a coupling 532, and are all arranged downstream of the feeding rack; the lower surface of the downstream of the feeding rack is fixedly connected to the upper surface of the mounting side seat 11. Under the action of the feeding drive mechanism 54 , the feeding chain 523 is rotated to drive the pipe to be continuously transported in the downstream direction.

[0065] The downstream of the feed rack is fixedly connected to the upper surface of the mounting side seat 11 . Compared with the existing feed rack in which the downstream is fixedly connected to the side wall of the bed 1 , the feed rack is closer to the loading mechanism 41 also mounted on the mounting side seat 11 .

[0066] See also Figure 8 In some embodiments, the feed rack includes two feed side plates 511 arranged parallel to and symmetrically with the pipe conveying direction, a vertical beam 513 fixedly connected to the upstream lower surfaces of the two feed side plates 511, and an upper connecting plate 512 fixedly connected to the upper surfaces of the two feed side plates 511. The upstream and downstream ends of the two feed side plates 511 are respectively provided with notches, and the feed driving wheel 521 and the feed driven wheel 522 are rotatably disposed in the corresponding notches. The feed side plates 511, the upper connecting plate 512, and the vertical beam 513 can be fixedly connected by welding. The outer surfaces of the feed side plates 511 are each provided with a bearing seat, allowing the feed transmission shaft 531 to rotate relative to the feed rack.

[0067] See also Figure 8 and Figure 9 In some embodiments, the feed drive mechanism 54 includes a feed motor mounting plate 541 disposed on the side wall of the mounting side seat 11, a feed drive motor 542 disposed on the feed motor mounting plate 541, a feed drive sprocket 543 disposed on the output end of the feed drive motor 542, a feed driven sprocket 544 sleeved on the feed transmission shaft 531, and a feed drive chain 545 wound between the feed drive sprocket 543 and the feed driven sprocket 544. When the pipe needs to be transported, the output end of the feed drive motor 542 rotates, driving the feed drive sprocket 543 to rotate. Under the drive of the feed drive chain 545 and the feed driven sprocket 544, the feed transmission shaft 531 is driven to rotate, which in turn drives the feed drive wheel 521 on the feed transmission shaft 531 to rotate, providing power for the feed chain 523.

[0068] As can be seen from the above description, the structures of the feeding conveying assembly 5 and the receiving conveying assembly 602 are basically the same. On the premise of meeting the functional requirements, the complexity of the pipe cutting machine can be reduced and the manufacturing cost can be reduced.

[0069] See also Figure 2In some embodiments, the plurality of feeding racks are detachably connected via feeding connecting rods 55, and the plurality of feeding connecting rods 55 are located upstream of the feeding racks. Since the feeding transmission shaft 531 is arranged downstream, a loading space is formed between the feeding racks, so that the pipes can be delivered to the loading space by a forklift, and the loading operation of the pipes can be completed with simple manual assistance. In addition, a crane can also be used for loading, providing users with a variety of loading methods. The short material conveying assembly 601 and the plurality of the receiving material conveying assemblies 602 are detachably connected via receiving connecting rods, and the plurality of the receiving material conveying assemblies 602 are located upstream of the short material conveying assembly 601 and the receiving material conveying assembly 602. By using the feeding connecting rods 55 and the receiving connecting rods, the plurality of feeding conveying assemblies 5, the receiving material conveying assembly 602 and the short material conveying assembly 601 can be detachable, which facilitates the shipment and transportation of each conveying assembly after disassembly, reduces the transportation volume, and allows for quick on-site installation.

[0070] See also Figure 9 4. The screw threaded hole 5442 of the first embodiment is connected to the support frame 541 of the second embodiment, and the screw threaded hole 5443 of the first embodiment is connected to the support frame 541 of the second embodiment.

[0071] The head of the tightening screw 5462 is again in close contact with the bottom surface of the adjusting block 546, which effectively prevents the tightening screw 5462 from loosening and plays an initial positioning role for the position of the feeding motor mounting plate 541. The workpiece personnel can apply force adjustment by tightening the tightening screw 5462 and the tightening screw 5461 with a hexagonal screwdriver. Finally, after adjusting the position of the feeding motor mounting plate 541, the fixing screw is locked to complete the adjustment of the feeding motor mounting plate 541. The adjustment operation is simple and accurate.

[0072] See also Figure 1 and Figure 2 In some embodiments, the outer cover of the feed drive mechanism 54 is provided with a feed protection cover 56. The provision of the feed protection cover 56 allows all transmission components to be located therein, thereby preventing debris from falling, thereby increasing the service life of the feed drive mechanism 54 and reducing the number of maintenance times.

[0073] See also Figure 8 In some embodiments, an end cover 514 is provided upstream of the two feeding side plates 511. The end cover 514 is used to shield the feeding driven wheel 522. The feeding driven wheel 522 is located upstream (i.e., on the operating side). The end cover 514 prevents the feeding driven wheel 522 from getting caught in clothing during rotation, thereby improving the safety of the loading rack.

[0074] See also Figure 8 In some embodiments, limit plates 515 are provided on both the upstream and downstream sidewalls of the feed side plate 511. Once the pipe is delivered downstream and in place, it still has a certain amount of inertia moving downstream. To prevent the pipe from sliding off the feed rack, the limit plates 515 are provided downstream, thereby improving the safety of the loading rack. The upstream limit plate 515 protects the feed driven wheel 522.

[0075] In the enclosed bevel pipe cutting equipment provided by the present invention, the feed drive mechanism 54 on the feed conveying assembly 5 is protected by a feed protective cover 56, and an end cover 514 and a limit plate 515 are provided to protect the feed driven wheel 522 and prevent the operator's clothes from being entangled; the first outer enclosing structure 7 and the second outer enclosing structure 9 are respectively used to protect the loading mechanism 51 in the loading area and the receiving mechanism 42 in the unloading area; the multiple protective covers 34 are provided to protect the three chuck structures; the protective box 8 is provided to protect the laser cutting assembly 2 in the cutting area, so as to maximize the protection of the pipe cutting equipment, extend the service life of the pipe cutting equipment, and reduce the number of maintenance times and costs.
