Description

Technical Field

[0001] This utility model relates to the field of pipe cutting and feeding technology, specifically to a limiting mechanism for an automatic pipe cutting and feeding machine. Background Technology

[0002] While conventional automatic pipe feeding machines can automatically feed pipes, different models are usually designed for a specific range of pipe specifications. If the pipe specifications to be processed exceed the applicable range of the feeding machine, it may not be able to feed properly or may require complex adjustments and modifications. If the pipe specifications to be processed are very small, it may result in feeding multiple pipes at once, making it impossible to cut a single pipe smoothly. Moreover, some automatic feeding machines have certain requirements for the shape of the pipes. For example, they may not be able to feed rectangular pipes well and may require special tooling fixtures to assist, which increases costs and complexity.

[0003] Therefore, it is necessary to invent a limiting mechanism for an automatic pipe cutting and feeding machine. Utility Model Content

[0004] Therefore, this utility model provides a limiting mechanism for an automatic pipe cutting and feeding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting mechanism for an automatic pipe cutting and feeding machine, including a frame, a plurality of end plates are longitudinally fixed at the top of the frame, a crossbeam is transversely fixed at the top of the rear end of the frame, a material storage component is fixed at the rear end of the frame, a feeding component is fixed between the frame and the end plates, and a limiting component is fixed at the front end of the crossbeam.

[0006] The limiting component includes several fixing plates. The rear ends of the fixing plates are longitudinally fixed to the front end of the crossbeam. The side ends of the fixing plates are vertically fixed with side plates. Limiting blocks are slidably installed on the surface of the side plates. The front ends of the limiting blocks are vertically fixed with racks.

[0007] Preferably, the limiting component further includes a motor frame, the rear end of which is fixed to one side of the front end of the crossbeam, a servo motor is laterally fixed to the side end of the motor frame, a connecting shaft is fixed to the output shaft of the servo motor, and a plurality of transmission gears are fixed to the surface of the connecting shaft, and the plurality of transmission gears mesh with a plurality of racks one by one.

[0008] Preferably, the storage assembly includes several vertically arranged storage racks, all of which are fixed to the rear end of the frame. A connecting plate is fixed to the top of the side end of each storage rack, and a feeding belt is fixed to each connecting plate.

[0009] Preferably, the feeding assembly includes a geared motor, the bottom of which is fixed to the bottom of the frame, and a transmission sprocket is fixed to the output shaft of the geared motor.

[0010] Preferably, a rotating shaft is rotatably mounted between the rear sides of two adjacent end plates, and a driven sprocket is fixed on the surface of the rotating shaft. The driven sprocket and the transmission sprocket are connected by a transmission chain.

[0011] Preferably, a plurality of take-up drums are fixed on the surface of the rotating shaft, and the front ends of the plurality of feeding belts are respectively fixed on the plurality of take-up drums.

[0012] Preferably, a traction shaft is rotatably mounted at the rear end between two adjacent end plates, and a plurality of traction rollers are fixed on the surface of the traction shaft, with the surfaces of the plurality of feeding belts respectively attached to the surfaces of the plurality of traction rollers.

[0013] The beneficial effects of this utility model are as follows: by using the frame, end plate, crossbeam, storage component, feeding component and limiting component in combination, the size of the feeding space behind the end plate can be flexibly adjusted, so that it can be well applied to the feeding operation of pipes of different specifications.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Please refer to the appendix. Figures 1-5 The limiting mechanism for the automatic pipe cutting and feeding machine provided by this utility model includes a frame 1, a plurality of end plates 2 are longitudinally fixed on the top of the frame 1, a crossbeam 3 is transversely fixed on the top of the rear end of the frame 1, a material storage component is fixed on the rear end of the frame 1, a feeding component is fixed between the frame 1 and the end plates 2, and a limiting component is fixed on the front end of the crossbeam 3.

[0022] The storage assembly includes several vertically arranged storage racks 4, which are all fixed to the rear end of the frame 1. A connecting plate 5 is fixed to the top of the side end of the storage rack 4, and a feeding belt 6 is fixed to the connecting plate 5. Specifically, the operator can stack the pipes to be cut horizontally on the feeding belt 6.

[0023] The feeding assembly includes a geared motor 7, which is fixed to the bottom of the frame 1. A transmission sprocket 8 is fixed to the output shaft of the geared motor 7. A rotating shaft 9 is rotatably mounted between two adjacent end plates 2. A driven sprocket 10 is fixed to the surface of the rotating shaft 9. The driven sprocket 10 and the transmission sprocket 8 are connected by a transmission chain 11. Specifically, when the geared motor 7 is running, it can drive the transmission sprocket 8 to rotate. Under the transmission action of the driven sprocket 10 and the transmission chain 11, the rotating shaft 9 can be controlled to rotate synchronously.

[0024] Several take-up drums 12 are fixed on the surface of the rotating shaft 9. The front ends of several feeding belts 6 are respectively fixed on the several take-up drums 12. A traction shaft 13 is rotatably installed between the rear ends of two adjacent end plates 2. Several traction rollers 14 are fixed on the surface of the traction shaft 13. The surfaces of several feeding belts 6 are respectively attached to the surfaces of several traction rollers 14. Specifically, when the rotating shaft 9 rotates, it can drive several take-up drums 12 to rotate synchronously, thereby winding up the feeding belts 6, tightening and moving the several feeding belts 6 upward, so that the pipes stacked on the several feeding belts 6 can move forward and then be fed through the rear end of the end plate 2.

[0025] The limiting assembly includes several fixed plates 15, the rear ends of which are longitudinally fixed to the front end of the crossbeam 3. Side plates 16 are vertically fixed to the sides of each fixed plate 15. Limiting blocks 17 are slidably mounted on the surfaces of the side plates 16. Racks 18 are vertically fixed to the front ends of each limiting block 17. The limiting assembly also includes a motor frame 19, the rear end of which is fixed to one side of the front end of the crossbeam 3. A servo motor 20 is laterally fixed to the side of the motor frame 19. A connecting shaft 21 is fixed to the output shaft of the servo motor 20. Several transmission gears 22 are fixed to the surface of the connecting shaft 21, and each of the transmission gears 22 meshes with one of the racks 18. Specifically… When the servo motor 20 is running, it can drive several transmission gears 22 to rotate synchronously in the forward and reverse directions through the connecting shaft 21. Under the transmission action of the rack 18, it can drive several limit blocks 17 to move synchronously up and down, thereby controlling the distance between several limit blocks 17 and the rear end of the end plate 2, thus realizing the function of flexibly adjusting the size of the feeding space behind the end plate 2. This makes it well applicable to the feeding operation of pipes of different specifications. Even if the pipe specifications are small, it can be fed individually. It can also effectively abut and limit the long side of the rectangular pipe, thus ensuring that the short side of the directional pipe can be stably fed behind the end plate.

[0026] It should be noted that this utility model is electrically connected to the external 220V mains power through the main controller, and the main controller can be existing technical equipment that controls gas distribution cabinets and power distribution cabinets (not marked in the figure).

[0027] The usage process of this utility model is as follows: During use, the operator can horizontally stack the pipes to be cut onto several feeding belts 6. Then, according to the actual specifications of the pipes to be cut, the servo motor 20 is controlled to move, i.e., the limit block 17 is controlled to move up and down to a suitable height, so that the limit block 17 and the feeding space behind the end plate 2 meet the requirements for a single pipe to pass through. Then, the reduction motor 7 is run, controlling the rotating shaft 9 to rotate synchronously. When the rotating shaft 9 rotates, it can drive several winding drums 12 to rotate synchronously, thereby winding up the feeding belts 6. This tightens and moves the feeding belts 6 upwards, allowing the pipes stacked on the feeding belts 6 to move forward, and then through the end plate 2... The rear end of plate 2 is used for feeding, which is suitable for feeding pipes of different specifications. Even if the pipe is small, it can be fed individually. When feeding rectangular pipes, the limiting block 17 and the feeding space behind the end plate 2 are controlled to allow the short side of the rectangular pipe to pass through. When the rectangular pipe moves to the rear end of the end plate 2, its top long side is abutted by the limiting block 17 and cannot move. As the feeding belt 6 continues to tighten and move upward, it can push the short side of the rectangular pipe to move forward, which can also effectively abut and limit the long side of the rectangular pipe, thus ensuring that the short side of the pipe can be stably fed behind the end plate.

[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
