Detailed Embodiment

[0025] The technical solution of the utility model will be described below in conjunction with the drawings and embodiments.

[0026] Such as Figures 1 to 4As shown in the figure, a metal tube feeding mechanism of the present utility model includes a material rack 2. A feeding end for feeding the metal tube 4 is provided at the first end of the material rack 2, and a discharging chute 3 for discharging the metal tube 4 is provided at the second end of the material rack 2. A limiting and guiding block 7 is provided at a position of the material rack 2 close to the discharging chute 3. The first end of the limiting and guiding block 7 is correspondingly arranged with the feeding end of the material rack 2. A limiting step 71 for limiting the metal tube 4 is provided at the first end of the limiting and guiding block 7. The second end of the limiting and guiding block 7 is correspondingly arranged with the discharging chute 3 for guiding the metal tube 4 to the discharging chute 3 for discharging. A jacking assembly is provided at a position of the material rack 2 close to the limiting and guiding block 7. The jacking assembly is located beside the limiting step 71 and is used for jacking up the metal tube 4 and guiding it to the discharging chute 3 for discharging through the limiting and guiding block 7. With such a setting, the metal tube 4 is placed on the material rack 2 through the previous process via the feeding end and abuts against the limiting step 71 for limiting. During feeding, the metal tube 4 located at the limiting step 71 is lifted by the jacking assembly. When the metal tube 4 is lifted to be flush with the upper surface of the limiting and guiding block 7, the metal tube 4 is guided to the discharging chute 3 for discharging, achieving the purpose of feeding to the next process. Its structure is simpler, the cost is lower, and manual cooperation for loading and unloading is not required during the feeding process, and the feeding efficiency is higher. In practical applications, the discharging chute 3 is correspondingly arranged with the material belt of the next process, and the metal tube 4 discharged through the discharging chute 3 can fall on the material belt of the next process.

[0027] In this embodiment, the upper surface of the material rack 2 is inclined, and the lower end is correspondingly arranged with the limiting and guiding block 7. With such a setting, when the metal tube 4 is placed on the material rack 2 through the previous process via the feeding end, under the action of the inclination of the upper surface of the material rack 2, the metal tube 4 automatically rolls to the limiting step 71 for limiting, facilitating subsequent jacking and discharging by the jacking assembly.

[0028] In this embodiment, the upper surface of the limiting and guiding block 7 is inclined, and the lower end is correspondingly arranged with the discharging chute 3. With such a setting, when the jacking assembly drives the metal tube 4 located at the limiting step 71 to rise to be flush with the upper surface of the limiting and guiding block 7, under the action of the inclination of the upper surface of the limiting and guiding block 7, the metal tube 4 automatically rolls to the discharging chute 3 for discharging to improve its feeding efficiency.

[0029] In this embodiment, the jacking assembly includes a cylinder 5 and a top plate 6. The cylinder 5 is fixedly installed on the material rack 2 through a fixing rod 51. The top plate 6 is fixedly connected to the output end of the cylinder 5. The top plate 6 is arranged corresponding to the metal pipe 4. The cylinder 5 is used to drive the top plate 6 to rise and fall. With such an arrangement, the cylinder 5 drives the top plate 6 to rise. The top plate 6 drives the metal pipe 4 located at the limit step 71 to rise. When the metal pipe 4 rises to be flush with the upper surface of the limit guiding block 7, the metal pipe 4 automatically rolls to the blanking chute 3 for blanking. After blanking is completed, the cylinder 5 drives the unloaded top plate 6 to fall to the initial position. At this time, the next metal pipe 4 automatically rolls to the limit step 71 under the action of the inclination of the upper surface of the material rack 2 for limiting, and works in a cycle to realize the sequential blanking of the metal pipes 4 located at the limit step 71 in sequence.

[0030] In this embodiment, the upper surface of the top plate 6 is inclined, and the lower side is arranged corresponding to the limit guiding block 7. With such an arrangement, when the top plate 6 jacks up the metal pipe 4 to be flush with the upper surface of the limit guiding block 7, under the action of the inclination of the upper surface of the top plate 6, the metal pipe 4 automatically rolls to the upper surface of the limit guiding block 7 and then automatically rolls along the upper surface of the limit guiding block 7 to the blanking chute 3 for blanking.

[0031] In this embodiment, a stop rack 21 is provided at the second end of the material rack 2. The blanking chute 3 is located between the limit guiding block 7 and the stop rack 21. With such an arrangement, when the metal pipe 4 automatically rolls along the upper surface of the limit guiding block 7 to the blanking chute 3, it is blocked by the stop rack 21 under the action of inertia and then blanked through the blanking chute 3.

[0032] Preferably, the height of the stop rack 21 is higher than the upper surface of the limit guiding block 7, so as to prevent the metal pipe 4 from flying out of the blanking chute 3 under the action of inertia.

[0033] It should be noted that the inertia of the rolling of the metal pipe 4 is related to the length of the upper surface of the limit guiding block 7. The shorter the upper surface of the limit guiding block 7, the smaller the inertia of the rolling of the metal pipe 4.

[0034] In this embodiment, an adjusting device for adjusting the height position of the limit guiding block 7 is provided on the material rack 2. With such an arrangement, the height of the limit guiding block 7 can be adjusted according to metal pipes 4 of different diameters. More specifically, the limit guiding block 7 can be adapted to the limit guiding function of metal pipes 4 of different diameters to improve the applicability of the limit guiding block 7.

[0035] In this embodiment, a sliding groove 17 is formed on the material rack 2, and the limiting and guiding block 7 is slidably arranged in the sliding groove 17 through a slider 9; the adjusting device includes a power component and a transmission component. The first end of the transmission component is connected to the power component, and the second end of the transmission component is connected to the limiting and guiding block 7. The power component is used to drive the transmission component to drive the limiting and guiding block 7 to slide up and down relative to the sliding groove 17. With this arrangement, the power component drives the transmission component to act, realizing the driving of the limiting and guiding block 7 to slide up and down in the sliding groove 17, and achieving the purpose of adjusting the limiting and guiding block 7.

[0036] In this embodiment, an installation cylinder 12 is formed on the material rack 2, and the installation cylinder 12 is located at the bottom of the sliding groove 17; the transmission component includes a threaded cylinder 8, a screw rod 10, a first bevel gear 11, a rotating shaft 13 and a second bevel gear 14. The threaded cylinder 8 is fixedly connected to the limiting and guiding block 7. The first end of the screw rod 10 is threadedly connected to the threaded cylinder 8. The second end of the screw rod 10 passes through the sliding groove 17 and is located in the installation cylinder 12. The first bevel gear 11 is fixed to the second end of the screw rod 10. The second bevel gear 14 is meshed and connected to the first bevel gear 11. The second bevel gear 14 is fixed on the rotating shaft 13. The first end of the rotating shaft 13 is movably arranged on the inner wall of the installation cylinder 12; the power component includes a handle 16 and a rotating disc 15, and the handle 16 is fixedly connected to the rotating disc 15; the second end of the rotating shaft 13 passes through the installation cylinder 12 and is fixedly connected to the rotating disc 15. With this arrangement, when it is necessary to adjust the height of the limiting and guiding block 7, the handle 16 is used to rotate the rotating disc 15. The rotating disc 15 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the second bevel gear 14 to rotate. The second bevel gear 14 drives the first bevel gear 11 to rotate. The first bevel gear 11 drives the screw rod 10 to rotate. Under the action of the threaded connection between the screw rod 10 and the threaded cylinder 8, it is realized to adjust the threaded cylinder 8 to drive the limiting and guiding block 7 to slide up and down in the sliding groove 17, and achieve the purpose of adjusting the height position of the limiting and guiding block 7.

[0037] Certainly, the power component can be driven by a motor, and the transmission component can also be a simpler connecting rod structure. For example, the motor drives the connecting rod to drive the limiting and guiding block 7 to move up and down, or the air cylinder drives the telescopic rod to drive the limiting and guiding block 7 to lift, both of which can achieve the purpose of the present invention.

[0038] In this embodiment, leveling devices for limiting the two ends of the metal pipe 4 are provided on both sides of the material rack 2, and a fixed seat 1 is provided at the bottom of the material rack 2. With this arrangement, the leveling device can make a plurality of metal pipes 4 on the material rack 2 level and arranged side by side, thereby facilitating the subsequent feeding of the metal pipes 4.

[0039] Preferably, the flush device can be guide plates symmetrically arranged on both sides of the rack 2. Of course, in order to adapt to the use of metal pipes 4 of different lengths, the guide plates on both sides can also be set to an adjustable width structure; in order to facilitate the metal pipe feeding mechanism to adapt to different processes, rollers can also be installed on the fixed seat 1 to facilitate mobile assembly. Since this technology is an existing technology, no specific description will be given here.

[0040] The embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the purpose of the present invention and the scope protected by the claims. All of these are within the protection scope of the present invention.
