Description
Technical Field
[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a pipe cutting machine feeding device. Background Technology
[0002] Pipes are important industrial materials, widely used in the construction industry, thermal equipment, and various types of machinery. Laser cutting is a new type of machining process with advantages such as high production efficiency, strong production capacity, and high flexibility; with the development of technology, its application in various machining fields is becoming increasingly widespread.
[0003] In pipe production, it is necessary to collect the cut pipes. Currently, existing pipe feeding devices (such as...) Figure 1 As shown, it mainly consists of a feeding mechanism 1 and a chain conveyor 2. After the cutting machine completes the cutting of the pipe, the feeding plate 12 set on the feeding mechanism 1 receives the pipe. The feeding plate 12 is flipped and tilted to a certain angle by a flipping device set at the bottom of the feeding plate 12, so that the cut pipe rolls down onto the chain conveyor 2 by gravity and is transported to the next process by the chain conveyor 2.
[0004] However, the cut pipes have a large gravitational potential energy during the process of rolling freely from the feeding mechanism 1 onto the chain conveyor 2, and there is no buffer or obstruction. This makes it easy for the pipes to collide violently with the chain conveyor 2, generating a lot of noise. For some pipes with high surface precision requirements, the collision process can easily cause damage or deformation to the pipe surface. In addition, the rolling pipes are also prone to problems such as being placed messily, unevenly, or falling off the chain conveyor 2. Utility Model Content

[0014] Preferably, a spring buffer for decomposing and absorbing the dynamic potential energy of the pipe is provided on one side of the baffle plate. The spring buffer is connected to the receiving frame by a universal joint, and the output end of the spring buffer is connected to the baffle plate in a transmission manner.
[0015] Preferably, the first lifting drive assembly includes a lifting slide rail, a slider, a connecting plate, and a synchronous lifting cylinder. The lifting slide rail is symmetrically arranged on both sides of the receiving frame.

[0018] Preferably, the feeding plate is further provided with a limiting block at one end of the roller to prevent the pipe from rolling off.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] This invention uses a first lifting drive component to match the tilt angle of the unloading mechanism in real time, avoiding height difference collisions when the pipe falls, thereby reducing the impact noise generated when the pipe falls.

[0032] The following is in conjunction with the appendix Figure 1-6 The present invention provides a more detailed description of an embodiment of a pipe cutting machine feeding device.
[0033] A pipe cutting machine feeding device, such as Figure 1-4 As shown, it includes a feeding mechanism 1 and a conveyor 2 disposed below the feeding mechanism 1. A receiving mechanism 3 is disposed between the feeding mechanism 1 and the conveyor 2. The receiving mechanism 3 includes...
[0034] The receiving rack 31 is set at the same height as the unloading rack 11, and the side wall of the receiving rack 31 is provided with a first lifting drive assembly 5;
[0035] The receiving plate 32 is set on the receiving frame 31 at the unloading position of the unloading mechanism 1. The receiving plate 32 is composed of a telescopic plate 321 and a baffle plate 322 connected by a hinge shaft. The included angle between the telescopic plate 321 and the baffle plate 322 forms a pipe receiving space.
[0036] The flipping drive assembly 33 is slidably connected to the first lifting drive assembly 5, and the flipping drive assembly 33 is connected to the receiving plate 32 for driving the receiving plate 32 to receive the pipe and then flip it to discharge it onto the conveyor 2.
[0037] The first lifting drive assembly 5 is used to dynamically adjust the height of the receiving plate 32 to match the tilt angle of the end of the unloading mechanism 1, so that the front end of the receiving plate 32 and the end of the unloading mechanism 1 form a continuous receiving surface.
[0038] Specifically, the step-by-step release of the pipe's potential energy is achieved through the coordinated control of the first lifting drive component 5 and the flipping drive component 33. The first lifting drive component 5 eliminates the drop caused by the change in the tilt angle of the unloading mechanism 1 through dynamic height adjustment, ensuring that the pipe is always in a controlled rolling state during the transfer process. During the flipping process, the receiving plate 32 decomposes the gravitational potential energy in the vertical direction into sliding kinetic energy along the inclined plane, and the guide effect of the baffle plate 322 ensures that the pipes are arranged in an orderly manner. The adaptive unfolding function of the telescopic plate 321 ensures that pipes of different lengths can fall completely into the receiving space, preventing deflection and collision caused by the end being suspended. The entire process replaces the traditional free-rolling unloading method through the motion sequence design of the mechanical structure.
[0039] In this embodiment, as Figure 6 As shown, the telescopic plate 321 and the baffle plate 322 form a V-shaped structure, and the included angle between the baffle plate 322 and the telescopic plate 321 is 45-90°.
[0040] Specifically, the precise receiving and orderly guidance of the pipe are achieved through dynamic angle adjustment and adaptive deployment functions. When the pipe slides out from the end of the feeding mechanism 1, the adjustable angle between the baffle plate 322 and the telescopic plate 321 forms a gradually narrowing guide channel. After the pipe slides in along the axial direction of the telescopic plate 321, its own weight causes the telescopic plate 321 to automatically extend to the appropriate length. At the same time, the baffle plate 322 dynamically adjusts its tilt angle through the hinge shaft, so that the center of gravity of the pipe is always in the middle of the V-shaped space, and ensures that it remains in a straight line when falling into the conveyor 2.
[0041] The V-shaped angle design decomposes the gravitational potential energy in the vertical direction into a tangential component along the inclined plane of the baffle plate 322, effectively reducing the instantaneous impact velocity of the pipe. The adjustable angle range allows the device to match the optimal guide angle according to the pipe diameter and weight characteristics, avoiding the bouncing problem caused by excessively steep inclines for small-diameter pipes. Furthermore, the angle adaptive characteristic enables the receiving mechanism 3 to smoothly transition between various cross-section pipes such as round, square, and irregularly shaped pipes, thus fundamentally solving the problems of pipe end impact, surface scratches, and stacking misalignment that exist in traditional free-rolling feeding methods.
[0042] In this embodiment, as Figure 6As shown, the telescopic plate 321 adopts a multi-level nested slide rail structure, and one end of the telescopic plate 321 is hinged to the baffle plate 322. One side of the telescopic plate 321 is fixed to the lifting drive assembly. A spring buffer 4 for decomposing and absorbing the dynamic potential energy of the pipe is provided on one side of the baffle plate 322. The spring buffer 4 is connected to the receiving frame 31 by a universal joint, and the output end of the spring buffer 4 is connected to the baffle plate 322 in a transmission connection.
[0043] Specifically, the sliding rail nesting structure of the telescopic plate 321 not only provides full-section support for pipes of different lengths, but its frictional damping during the extension process can further consume the kinetic energy of the pipes. Together with the spring buffer 4 on the baffle plate 322, it forms a dual shock absorption mechanism, completely eliminating the risk of rigid collisions with the pipes.
[0044] In this embodiment, as Figure 4 , 6 As shown, the first lifting drive assembly 5 includes a lifting slide rail 51, a slider 52, a connecting plate 53, and a synchronous lifting cylinder 54. The lifting slide rail 51 is symmetrically arranged on both sides of the receiving frame 31. The slider 52 is slidably connected to the lifting slide rail 51, and one side of the slider 52 is connected to the output end of the synchronous lifting cylinder 54. One end of the connecting plate 53 is fixed to the slider 52, and the other end is fixedly connected to the receiving plate 32.
[0045] In this embodiment, as Figure 2 , 4 As shown in Figure 6, the flip drive assembly 33 includes a servo motor 331, a rotating shaft 332, and a coupling 333. The output end of the servo motor 331 is connected to the rotating shaft 332 via the coupling 333, and the servo motor 331 is fixedly mounted on the receiving frame 31. The rotating shaft 332 passes laterally through the receiving frame 31 and is connected to the hinge shaft. A bearing assembly 334 is provided between the rotating shaft 332 and the receiving plate 32.
[0046] Specifically, after the pipe is positioned within the receiving plate 32, the servo motor 331 transmits power to the rotating shaft 332 via the coupling 333, driving the rotating shaft 332, which passes through the receiving frame 31, to rotate at a precise angle. At this time, the hinge shaft, which is coaxially driven with the rotating shaft 332, drives the receiving plate 32 to rotate slowly around its axis. During this process, the bearing assembly 334, located between the rotating shaft 332 and the receiving plate 32, effectively eliminates rotational friction, allowing the receiving plate 32 to smoothly transition from a horizontal support state to an inclined unloading state. The pipe gains controllable acceleration as the tilt angle of the receiving plate 32 changes linearly, and finally slides orderly into the conveyor 2 along the inclined surface of the baffle plate 322.
[0047] In this embodiment, as Figure 2-5As shown, the unloading mechanism 1 includes an unloading frame 11, an unloading plate 12, and a tilting cylinder 13. A second lifting drive assembly 6 is provided on one side of the unloading frame 11. The unloading plate 12 is slidably connected to the lifting assembly, and multiple mounting holes 121 are opened in parallel on the unloading plate 12. Rollers 14 are provided in the mounting holes 121, and the two ends of the rollers 14 are rotatably connected to the unloading plate 12. The bottom end of the tilting cylinder 13 is connected to the second lifting drive assembly 6 through a hinge seat. The output end of the tilting cylinder 13 is connected to the unloading plate 12 in a transmission manner.
[0048] Specifically, when the cut pipe is conveyed to the end of the unloading plate 12 via roller 14, the second lifting drive assembly 6 drives the unloading plate 12 to lift as a whole. At the same time, the tilting cylinder 13 pushes the unloading plate 12 to rotate around the hinge point through the hinge seat, so that the plane of roller 14 forms an inclination angle that matches the receiving mechanism 3. During this process, the parallel rollers 14 continue to rotate, which reduces the sliding friction resistance of the pipe and constrains the axial displacement of the pipe through the limiting block 15. Until the inclination angle of the unloading plate 12 is aligned with the height of the receiving plate 32, the pipe slides smoothly into the V-shaped receiving space of the receiving mechanism 3 along the tangential direction of roller 14.
[0049] The second lifting drive assembly 6 adopts the same structure as the first lifting drive assembly 5. It is fixedly connected to the unloading frame 11 by the lifting slide rail 51, and the slider 52 is slidably connected on the lifting slide rail 51, so that the connecting plate 53 can drive the unloading plate 12 to move up and down along the unloading frame 11. This allows for dynamic adjustment according to different cutting machine heights, so that the unloading plate 12 can stably transport pipes and unload them.
[0050] It is worth noting that a limiting block 15 is also provided at one end of the feeding plate 12 located on the roller 14. The function of the limiting block 15 is to prevent the feeding plate 12 from rolling off the pipe while receiving it, and at the same time to ensure that the pipe is fed in the specified direction.
[0051] The pipe cutting process in this utility model is as follows:
[0052] When the cut pipe is output at an angle along the unloading mechanism 1, the first lifting drive component 5 adjusts the height of the receiving plate 32 in real time, so that the front end of the telescopic plate 321 and the end of the unloading mechanism 1 form a continuous supporting surface. The pipe smoothly transitions into the V-shaped receiving space of the receiving plate 32 by rolling or sliding. At this time, the telescopic plate 321 automatically unfolds according to the length of the pipe, and the baffle plate 322 guides and limits the pipe through the included angle formed by the hinge shaft. After the pipe has completely entered the receiving plate 32, the flipping drive component 33 drives the receiving plate 32 to slowly flip around the hinge shaft. By controlling the flipping angle, the pipe slides into the conveyor 2 along the inclined surface of the baffle plate 322 at a controlled speed, avoiding the impact caused by free fall.
[0053] This technical solution effectively solves the problems of collision damage and disordered arrangement during pipe feeding. Because the pipes are in a controlled transfer state throughout the process, direct impact with the conveyor 2 is avoided, significantly reducing the risk of surface scratches and deformation. Simultaneously, the receiving plate 32, in conjunction with the flipping drive assembly 33, precisely controls the flipping angle, ensuring that the pipes are axially aligned with the conveyor 2's transport direction during feeding. Furthermore, the dynamic lifting adjustment function of the first lifting drive assembly 5 enhances adaptability to different pipe specifications and feeding angles, making it particularly suitable for automated feeding operations of precision pipes such as stainless steel and aluminum alloy pipes. Compared to traditional feeding devices, this invention achieves a comprehensive improvement in pipe conveying quality and equipment versatility while ensuring feeding efficiency.
[0054] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
