[0022] The following combination Figures 1 to 4 Embodiments of the present invention are described.

[0023] A material receiving rack in this embodiment includes: A lower frame 101 is provided with a horizontal slide rail 103 along its length; An upper frame 102, wherein a horizontal slider 104 is provided at the bottom of the upper frame 102, and the horizontal slider 104 is slidably connected to the horizontal slide rail 103; The avoidance cylinder 201 has a fixed portion fixedly connected to the lower frame 101 and a movable portion drivingly connected to the upper frame 102; The follow-up material receiving mechanism is provided on the upper frame 102 and is used for receiving the pipe material.

[0024] In this embodiment, the lower frame 101 serves as the basic supporting structure, and the horizontal slide rails 103 are arranged along the length direction of the lower frame 101, providing a precise guide path for the upper frame 102 to ensure that the upper frame 102 remains stable and without deviation during the movement; a plurality of horizontal sliders 104 are distributed at the bottom of the upper frame 102, and the horizontal sliders 104 are slidably connected with the horizontal slide rails 103, so that the upper frame 102 can move along the horizontal slide rails 103; the avoidance cylinder 201 serves as a power source, and the avoidance cylinder 201 is used to drive the upper frame 102 to move back and forth along the slide rails, so that the follow-up material receiving mechanism provided on the upper frame 102 can quickly avoid the pipe cutting machine chuck, effectively solving the problem in the prior art that the material receiving frame is difficult to quickly avoid when cutting tail materials, thereby significantly improving the continuity and production efficiency of the cutting operation; The avoidance principle is as follows: when the material receiving rack does not need to avoid the pipe cutting machine chuck, the movable part of the avoidance cylinder 201 is in an extended state, so that the upper frame 102 moves along the horizontal slide rail 103 to a position close to the pipe cutting machine chuck; when the material receiving rack needs to avoid, the avoidance cylinder 201 is started, and its movable part begins to retract, pulling the upper frame 102 along the horizontal slide rail 103 through the connecting plate 204, gradually away from the pipe cutting machine chuck, and the upper frame 102 and the follow-up material receiving mechanism thereon quickly leave the working area of ​​the pipe cutting machine chuck; after the pipe cutting machine completes cutting the tail material, the avoidance cylinder 201 reverses and its movable part extends again, restoring the upper frame 102 to its initial position; Because when the avoidance cylinder 201 contracts, a pulling force is applied to the upper frame 102, the force is more stable, the positioning accuracy is higher, the avoidance control is more accurate, and the shaking or deviation of the upper frame 102 caused by excessive thrust is avoided.

[0025] Specifically, the material receiving rack also includes a connecting plate 204, a hydraulic buffer 202 and a limit baffle 203; the movable part of the avoidance cylinder 201 is transmission-connected to the upper frame 102 through the connecting plate 204; the fixed part of the hydraulic buffer 202 is fixedly connected to the lower frame 101, and the movable part of the hydraulic buffer 202 is arranged on the movement path of the movable part of the avoidance cylinder 201; the limit baffle 203 is fixedly connected to the lower frame 101 and is located at the end of the movement path of the movable part of the avoidance cylinder 201; when the movable part of the avoidance cylinder 201 moves, the connecting plate 204 first abuts against the movable part of the hydraulic buffer 202 to buffer and decelerate, and then abuts against the limit baffle 203 to stop movement.

[0026] When the upper frame 102 is about to move to the upper position, the upper frame 102 is moved to the upper position by the upper frame 102. By arranging the hydraulic buffer 202 and the limit baffle 203 on the movement path of the movable part of the avoidance cylinder 201, the overshoot phenomenon caused by the excessive extension of the avoidance cylinder 201 is avoided, and the stability of the equipment is enhanced.

[0027] Specifically, the follow-up material receiving mechanism includes a driving component, a lifting and adjusting component, an inclination adjustment component and a flap 601; the lifting and adjusting components and the inclination adjustment components are provided in plurality; a plurality of the lifting and adjusting components are arranged on the upper frame 102 and are distributed along the length direction of the upper frame 102; the lifting and adjusting component is transmission-connected with the flap 601; each of the lifting and adjusting components is transmission-connected with a corresponding inclination adjustment component; the inclination adjustment component is transmission-connected with the flap 601; the driving component is arranged on the upper frame 102, and a plurality of the lifting and adjusting components are transmission-connected through the driving component.

[0028] In this embodiment, the driving assembly serves as a power source, is started when the material receiving rack is working, and transmits power to the lifting and adjusting assembly through the transmission component; the lifting and adjusting assembly starts working after receiving the power transmitted by the driving assembly, and raises or lowers the flap 601 to a suitable position; the inclination adjustment assembly works on the basis of the lifting and adjusting assembly, pushing the flap 601 to rotate, thereby changing the angle between the flap 601 and the horizontal plane to adapt to different pipe receiving and conveying requirements; by respectively setting the lifting and adjusting assembly and the inclination adjustment assembly, the height and angle of the flap 601 can be adjusted independently and accurately; by distributing a plurality of lifting and adjusting assemblies and the inclination adjustment assemblies along the length direction of the upper frame 102, the support points and adjustment points of the flap 601 are increased, and the stability of the adjustment process is improved; when adjusting the height and angle of the flap 601, the force can be distributed more evenly, the shaking and deformation of the flap 601 can be reduced, and the smoothness of the material receiving process can be ensured.

[0029] Specifically, the drive assembly includes a servo motor 301, a transmission shaft 302 and a plurality of transmission gears 303 distributed along the length direction of the transmission shaft 302; the servo motor 301 is arranged on the upper frame 102; the output end of the servo motor 301 is connected to the transmission shaft 302, and the transmission shaft 302 is coaxially connected to all the transmission gears 303; each of the transmission gears 303 is respectively connected to the corresponding lifting and adjusting assembly.

[0030] When the height of the flap 601 needs to be adjusted, the servo motor 301 is started; the servo motor 301 serves as a power source, converting electrical energy into mechanical energy and outputting rotational power through its output end; the output end of the servo motor 301 can be connected to the transmission shaft 302 through a coupling; the rotation of the transmission shaft 302 drives the transmission gear 303 coaxially connected thereto to rotate, and since the transmission gear 303 is meshed with the vertical rack 406, the rotation of the transmission gear 303 causes the vertical rack 406 to perform a linear motion along the rotation direction of the transmission gear 303, thereby driving the mounting member 401 to move up and down, and the mounting member 401 is connected to the flap 601 through the first hinge 402, thereby realizing the height adjustment of the flap 601; The servo motor 301 has stable power output characteristics, can provide continuous and reliable power support for the lifting and adjusting components, and can be precisely controlled through the electrical control system, and can easily realize forward and reverse rotation, speed regulation and other functions. The operator can flexibly adjust the speed and direction of the height adjustment of the flap 601 according to the actual material receiving requirements.

[0031] Specifically, the lifting and adjusting assembly includes a mounting member 401, a first hinge member 402 and a vertical slider 403; the vertical slider 403 is fixedly connected to the upper frame 102, and the mounting member 401 is provided with a vertical slide rail 404, and the vertical slider 403 is slidingly connected to the vertical slide rail 404; the vertical slider 403 is provided with a first bearing seat 405, and the transmission shaft 302 is installed in the first bearing seat 405; the mounting member 401 is also provided with a vertical rack 406, and the vertical rack 406 is engaged with the transmission gear 303; the top end of the mounting member 401 is hinged to the flap 601 through the first hinge member 402, and the mounting member 401 is fixedly connected to the inclination adjustment assembly.

[0032] After the driving assembly is started, the power is transmitted to the transmission shaft 302; since the transmission shaft 302 is coaxially connected with the transmission gear 303, the rotation of the transmission shaft 302 will drive the transmission gear 303 to rotate synchronously; and the transmission gear 303 is meshed with the vertical rack 406. When the transmission gear 303 rotates, according to the transmission principle of the gear rack, relative motion will be generated on the vertical rack 406. Since the vertical rack 406 is fixed on the mounting member 401, the rotation of the transmission gear 303 will cause the mounting member 401 to perform a linear motion in the vertical direction relative to the upper frame 102 During the up and down movement of the mounting member 401, the sliding cooperation formed by the vertical slider 403 and the vertical slide rail 404 plays a guiding role, so that the vertical slider 403 slides smoothly along the vertical slide rail 404, ensuring that the mounting member 401 can only make linear movements in the vertical direction, avoiding shaking and deviation during the movement, thereby ensuring the stability of the height adjustment of the flap 601; the top end of the mounting member 401 is hinged to the flap 601 through the first hinge 402, and the movement of the mounting member 401 is transmitted to the flap 601 through the first hinge 402, thereby realizing the height adjustment of the flap 601; The inclination adjustment assembly is fixedly connected to the mounting member 401. During the height adjustment process, the change in the position of the mounting member 401 will be transmitted to the inclination adjustment assembly, so that the inclination adjustment assembly will change in height synchronously with the flap 601; ensuring that when the inclination adjustment assembly adjusts the flap 601, its adjustment function only involves angle changes but not height changes; for example, when the flap 601 is raised or lowered due to the action of the lifting adjustment assembly, the inclination adjustment assembly will also rise or fall synchronously, but its internal adjustment mechanism will only adjust the angle of the flap 601, ensuring that the flap 601 can be at a suitable inclination angle at different heights to accommodate the pipe material.

[0033] Specifically, the inclination adjustment assembly includes a connecting member 501, a driving cylinder 502 and a second hinge 503; the connecting member 501 is fixedly connected to the mounting member 401, the fixed part of the driving cylinder 502 is hinged to the connecting member 501, and the movable part of the driving cylinder 502 is hinged to the flap 601 through the second hinge 503.

[0034] When the lifting and adjusting assembly works, driving the mounting member 401 to move up and down to adjust the height of the flap 601, since the mounting member 401 is fixedly connected to the connecting member 501, the connecting member 501 will change in height synchronously with the mounting member 401, thereby achieving coordination between the angle adjustment process and the height adjustment process; while the height of the flap 601 changes, the inclination adjustment assembly can synchronously adjust the angle of the flap 601, ensuring that the material receiving rack can accurately receive pipe materials at different heights and angles; When the angle of flap 601 needs to be adjusted, the drive cylinder 502 begins operating. If the active portion of the drive cylinder 502 extends, it applies a thrust to flap 601 via the second hinge 503, causing flap 601 to rotate about the hinge point between the first hinge 402 and the mounting member 401, thereby changing the angle of flap 601. If the active portion of the drive cylinder 502 retracts, it applies a pulling force to flap 601, causing flap 601 to rotate in the opposite direction, achieving reverse angle adjustment. By precisely controlling the extension and retraction of the active portion of the drive cylinder 502, flap 601 can be adjusted to the desired tilt angle to accommodate different pipe handling requirements.

[0035] Specifically, a mounting groove is provided on the flap 601 along its width direction, and second bearing seats 802 are fixed at both ends of the mounting groove. A roller shaft 801 is rotatably connected between the two second bearing seats 802; the highest point of the outer peripheral surface of the roller shaft 801 is higher than the plate surface of the flap 601.

[0036] When the pipe is conveyed to the flap 601 of the receiving rack, the pipe will first contact the roller 801 because the highest point of the outer circumference of the roller 801 is higher than the surface of the flap 601; under the action of the pipe's own gravity and the subsequent conveying force, the roller 801 will rotate around its axis in the second bearing seat 802. This rotation can reduce the friction between the pipe and the flap 601, so that the pipe can move more smoothly on the surface of the flap 601, which helps to improve the conveying efficiency of the pipe and reduce the jamming and wear of the pipe during the conveying process.

[0037] Specifically, the material receiving rack further includes a material platform 701 , and the material platform 701 is located on one side of the lower frame 101 , and the flap 601 is tilted toward one side of the material platform 701 .

[0038] When the pipe is conveyed to the flap 601 of the automatic material receiving rack, since the flap 601 is inclined toward the side of the material platform 701, under the action of the pipe's own gravity, the pipe will automatically slide toward the material platform 701 along the inclined flap 601; in this way, the automatic transfer of the pipe from the flap 601 to the material platform 701 is realized without the need for additional power equipment to push the pipe to move.

[0039] Specifically, the material platform 701 is provided with a first baffle 702 and a second baffle 703 on both sides in the length direction; the first baffle 702 and the second baffle 703 are both extended along the length direction of the material platform 701; the first baffle 702 is vertically arranged on the side away from the lower frame 101; the second baffle 703 is arranged on the side close to the lower frame 101, and its upper end is inclined toward the side of the lower frame 101.

[0040] In this embodiment, the first baffle 702 is vertically arranged on the side away from the lower frame 101 and extends along the length direction of the material platform 701, which can cover the entire width range of the material platform 701, ensuring that the pipe will not fall from the outside of the material platform 701; the second baffle 703 is arranged on the side close to the lower frame 101, and its upper end is inclined toward the side of the lower frame 101, which is used to guide the pipe to slide to the center area of ​​the material platform 701 to avoid the pipe from accumulating or getting stuck at the edge of the material platform 701; the first baffle 702 and the second baffle 703 together constitute the protective structure of the material platform 701, ensuring the stability and safety of the pipe on the material platform 701, and reducing the risk of the pipe falling from the material platform 701.

[0041] Specifically, the flap 601 is provided with a protective baffle 602 on a side away from the material platform 701 , and the protective baffle 602 is extended along the length direction of the flap 601 .

[0042] Regardless of whether the flap 601 is tilted or horizontal, the protective baffle 602 can prevent the pipe from falling to the side other than the material platform 701, ensuring that the pipe can only slide or move toward the material platform 701.
