The output end of the worm gear screw jack is fixedly connected to the side wall of the slide block. The input shafts of multiple adjacent worm gear screw jacks are connected to a synchronous shaft two via a coupling. The synchronous shaft two is rotatably connected to the feeding frame. One end of the synchronous shaft two passes through the feeding frame and is coaxially fixedly connected to a handwheel.

[0011] Preferably, the feeding mechanism includes multiple cylinders II, the number of which is the same as the feeding frame. Each cylinder II is installed on the side wall of each feeding frame away from cylinder I. The output direction of cylinder II is the same as the conveying direction of chain I. The output end of each cylinder II is fixedly connected to a feeding seat. The side wall of the feeding seat away from the feeding frame is fixedly connected to a support plate.

[0015] Improving the accuracy of steel pipe feeding: The steel pipe is initially centered by the V-shaped positioning groove at the top of the top plate. The positioning block and limit switch achieve precise stopping of the steel pipe conveying. The cylinder four on the baffle and the limit plate complete the alignment of the steel pipe end. The V-shaped opening and closing limit structure of the curved arm and the support plate in the feeding mechanism ensures the stability of the steel pipe posture during the pushing process.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] like Figures 1-7 As shown, a feeding device for a steel pipe cutting machine includes a frame 1. A control box is installed on the side wall of the frame 1. The control box is electrically connected to various electrical control components in the device. The controller is electrically connected to various electrical control components in the device. The frame 1 has a conveying direction. A conveying component 2 is installed on the top of the frame 1 along the conveying direction. A lifting mechanism 3 is installed downstream of the conveying component 2 to lift a steel pipe and pause the conveying component 2. A feeding mechanism 4 is installed on one side of the lifting mechanism 3 to push the steel pipe to the roller at the cutting station.

[0021] Furthermore, the frame 1 includes multiple spaced feeding racks 11, with connecting rods 12 fixedly connected between adjacent feeding racks.

[0022] Furthermore, the conveying assembly 2 includes multiple chains 21. Each feeding frame 11 has a sprocket 22 and a sprocket 23 installed inside it along its length. The conveying direction of the frame 1 is from sprocket 22 to sprocket 23. Chains 21 are meshed between sprocket 22 and sprocket 23. The upper segment of chain 21 is located above the feeding frame 11. A drive motor 24 is installed in one of the feeding frames 11. A sprocket 25 is fixedly connected to the surface of the drive motor output shaft 24. Multiple sprockets 22 are coaxially connected via a coupling for synchronous transmission. The synchronous shaft 26 is rotatably connected to multiple feeding racks 11. A sprocket 27 is fixedly connected to the surface of the synchronous shaft 26. A chain 28 meshes between the sprocket 27 and the chain 25. After the drive motor 24 starts, the synchronous shaft 26 is driven to rotate through the transmission cooperation of the chain 25, the chain 28 and the chain 27. The synchronous shaft 26 then links the sprockets 22 in all the feeding racks 11 through the coupling, so that multiple chains 21 rotate synchronously and move along the conveying direction to realize the batch conveying of multiple steel pipes.

[0023] Furthermore, the lifting mechanism 3 includes multiple cylinders 31, which are activated by a controller to achieve synchronous telescopic movement, forming a synchronous drive structure. The number of cylinders 31 is the same as that of the feeding frame 11. Each cylinder 31 is located on the side of each feeding frame 11 near the sprocket 23. Displacement components 32 for adjusting the position of the cylinders 31 are provided between the multiple feeding frames 11 to ensure that steel pipes of different specifications can be stably lifted and detached from the conveying component. The output end of each cylinder 31 is fixedly connected to a top plate 35. Each top plate 35 has a V-shaped positioning groove at its top. Each feeding rack 11 has a positioning block 33 fixedly connected to its top near the sprocket 23. A limit switch 34 for triggering the suspension of the conveying assembly 2 is installed on one side of the positioning block 33. The limit switch 34 is preferably an Omron rocker-type limit switch. When the steel pipe touches the limit switch 34 on the side of the positioning block 33, the limit switch 34 triggers a signal to stop the conveying assembly 2. At the same time, the cylinder 31 starts to lift the steel pipe, completing the separation and positioning of a single steel pipe.

[0024] Furthermore, the displacement assembly 32 includes multiple slide rails 321, the number of which is the same as the number of feed racks 11. Each slide rail 321 is fixedly connected to one side wall of each feed rack 11 near the second sprocket 23. A slide block 322 is slidably connected in each slide rail 321. The side wall of the slide block 322 away from the slide rail 321 is fixedly connected to the first cylinder 31. A worm gear screw jack 323 is installed on one side of each slide rail 321, and the output end of the worm gear screw jack 323 is fixedly connected to the side wall of the slide block 322. The input shafts of multiple adjacent screw jacks 323 are connected by a coupling to a synchronous shaft 324. The synchronous shaft 324 is rotatably connected to the feeding frame 11. One end of the synchronous shaft 324 passes through the feeding frame 11 and is coaxially fixed to a handwheel 325. Rotating the handwheel 325 can drive the synchronous shaft 324 to rotate, thereby driving all screw jacks 323 to synchronously push the slide block 322 to slide along the slide rail 321, thus realizing the synchronous position adjustment of multiple cylinders 31.

[0025] Furthermore, the feeding mechanism 4 includes multiple cylinders 41, which are activated by a controller to achieve synchronous telescopic movement, forming a synchronous drive structure. The number of cylinders 41 is the same as that of the feeding frame 11. Each cylinder 41 is installed on the side wall of each feeding frame 11 away from cylinder 31. The output direction of cylinder 41 is consistent with the conveying direction of chain 21. The output end of each cylinder 41 is fixedly connected to a feeding seat 42. A support plate 43 is fixedly connected to the side wall of the feeding seat 42 away from the feeding frame 11. The top of the support plate 43 is provided with an inclined surface. The horizontal height of the lower edge of the inclined surface of the top of the support plate 43 is higher than the horizontal height of the chain segment on chain 21, avoiding... To prevent frictional interference between the steel pipe and the conveying assembly 2 during pushing, a crank arm 44 is rotatably connected to the side wall of the support plate 43 away from the feeding seat 42 via a rotating shaft. A cylinder 45 is also installed on the side wall of the support plate 43 away from the feeding rack 11. Multiple cylinders 45 are started by a controller to achieve synchronous telescopic movement, forming a synchronous drive structure. The output end of the cylinder 45 is hinged to the bottom end of the crank arm 44. The inclined surface of the crank arm 44 and the top of the support plate 43 can be enclosed to form a letter V-shaped opening and closing limiting structure. The V-shaped limiting structure can limit the steel pipe, prevent deviation during pushing, and ensure that the steel pipe moves along the set path. The telescopic movement of the cylinder 45 drives the crank arm 44 to rotate, realizing the opening and closing of the limiting structure.

[0026] Furthermore, each feeding seat 42 is equipped with a slide rail 46 on its side wall near the feeding frame 11, and each feeding frame 11 is equipped with a slider 47 on its side wall near the feeding seat 42. Each slider 47 is slidably connected to the corresponding slide rail 46. The sliding engagement between the slide rail 46 and the slider 47 on the feeding frame 11 guides the extension and retraction of the cylinder 41. A rack 48 is fixedly connected to the bottom of each feeding seat 42, and a gear 49 is meshed below the rack 48. Multiple gears 49 are connected to a synchronous shaft 410 via a coupling. The synchronous shaft 410 is rotatably connected to multiple feeding frames 11, and the multiple gears 49 are linked through the synchronous shaft 410, enhancing the synchronicity of all feeding seats 42 under the drive of the cylinder 41.

[0027] Furthermore, a baffle 411 is fixedly connected to the side wall of the outermost feeding rack 11 away from the other feeding racks 11. A cylinder 412 is installed on the top of the baffle 411 near the side of the sprocket 23. A limit plate 413 is fixedly connected to the output end of the cylinder 412. When the steel pipe is lifted into the V-shaped limit structure, the cylinder 412 is activated to push the limit plate 413 against the end of the steel pipe, so that the steel pipe is parallel to the cutting station roller.

[0028] Working principle: The operator places multiple steel pipes parallel on the chain segments of chain 21 above multiple feeding racks 11, starts the drive motor 24 to drive sprocket 25 to rotate, and transmits the power through chain 28 to sprocket 27 on synchronous shaft 26, thereby driving synchronous shaft 26 to rotate synchronously. Synchronous shaft 26 drives sprocket 22 in all feeding racks 11 to rotate synchronously through the coupling, so that chain 21, which is meshed between sprocket 22 and sprocket 23, runs along the conveying direction of the frame 1. The continuous movement of chain 21 drives the steel pipe to move downstream of the conveyor.

[0029] When the downstream steel pipe moves with chain 21 to a position close to sprocket 23, the surface of the steel pipe comes into contact with positioning block 33 and touches the limit switch 34 on one side of positioning block 33. Limit switch 34 immediately triggers a signal and feeds back to the control module, controlling drive motor 24 to stop running. Chain 21 stops conveying, and at the same time, multiple cylinders 31 in lifting mechanism 3 start synchronously. Their output ends push top plate 35 to extend upward. The V-shaped positioning groove at the top of top plate 35 accurately supports the single steel pipe and lifts it off chain 21. After top plate 35 lifts the single steel pipe, limit switch 34 no longer senses the steel pipe. The control module feeds back a signal to drive motor 24 to start again, chain 21 resumes operation, and drives subsequent steel pipes to continue to be conveyed to positioning block 33, preparing for the next feeding.

[0030] Then, cylinder 345 retracts, bringing support plate 43 and top plate 35 to the same horizontal position. Subsequently, cylinder 131 retracts synchronously, causing top plate 35 to descend. Since the lower edge of the inclined surface of support plate 43 is higher than the upper chain segment of chain 21, the steel pipe falls into the V-shaped opening and closing limiting structure during the descent of top plate 35. Then, cylinder 412 on the baffle 411 is activated, and its output end pushes the limiting plate 413 to extend towards the end of the steel pipe. The limiting plate 413 abuts against the end of the steel pipe, pushing the steel pipe axis parallel to the cutting station roller. Subsequently, cylinder 2 41 starts and pushes the feeding seat 42 to move towards the cutting station roller. When the V-shaped opening and closing limit structure moves above the cutting station roller, cylinder 3 45 retracts, and its output end pulls the crank arm 44 to rotate around the shaft, releasing the V-shaped limit constraint. The steel pipe falls smoothly onto the cutting station roller along the top wall of the crank arm 44, completing a single feeding. Afterward, cylinder 2 41, cylinder 3 45, and cylinder 412 reset in sequence, the top plate 35 returns to its initial position, and the device enters the feeding cycle of the next steel pipe, realizing continuous feeding.
