Technical Field
[0001] This utility model relates to the field of pipe cutting technology, and in particular to an automatic fixed-length cutting device for corrugated pipes. Background Technology
[0002] As a type of flexible pipe, corrugated pipes are widely used in industrial fluid transportation, mechanical seals, automotive exhaust systems and other fields. During the production process, corrugated pipes need to be cut into specific lengths according to usage requirements. Therefore, fixed-length cutting devices have become one of the key equipment in corrugated pipe processing.
[0003] Currently, common corrugated pipe cutting devices typically use a conveying mechanism in conjunction with a cutting tool to achieve fixed-length cutting. Some devices use a rotating wheel to move the corrugated pipe, and when it reaches the set length, a mechanical limit device controls the cutting length, and the cutting mechanism completes the cutting. Although these devices achieve automated cutting, they still have shortcomings in terms of fixed-length control.
[0004] Currently, in practical applications, cutting devices using a baffle-type fixed-length structure suffer from several problems. The corrugated surface of the pipe causes slippage when the baffle contacts the pipe, leading to decreased fixed-length accuracy. Furthermore, the traditional linear cutting motion of the blade can result in uneven cuts due to pipe deformation during the cutting process. While some devices attempt to fix the pipe by adding clamping mechanisms, the complex structure increases the device's size, hindering the layout of compact production lines. Therefore, an improved solution is needed that balances fixed-length accuracy, cutting quality, and structural compactness. This paper proposes an automatic fixed-length cutting device for corrugated pipes to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic fixed-length cutting device for corrugated pipes, which aims to improve the problems of insufficient fixed-length cutting accuracy, easy deformation during cutting, and complex structure in the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic fixed-length cutting device for corrugated pipes includes a machine body, a fixed-length cutting component is provided inside the machine body, and a fixing component is provided inside the machine body. The fixed-length cutting assembly includes a bracket, with one side of each bracket fixedly connected to the inside of the machine body. Each bracket has a support column fixedly connected to one side, and one end of each support column is rotatably connected to a rotating column. Fixed-length wheels are arranged between the brackets. A support assembly is provided on one side of one of the brackets. Multiple baffles are fixedly connected to the outer side of each fixed-length wheel. Multiple guide columns are fixedly connected to one side of each fixed-length wheel. Guide plates are rotatably connected to the side walls of each guide column. A spring is arranged between the guide plates, with both ends of the spring fixedly connected to one side of each guide plate. A blade holder is fixedly connected to one side of each guide plate, and a cutting blade is fixedly connected to one side of each blade holder.

A motor is provided on the top of the base, and the output end of the motor is fixedly connected inside the fixed-length wheel.

[0014] This utility model has the following beneficial effects: 1.

[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] Reference Figures 1-3This utility model provides an embodiment of an automatic fixed-length cutting device for corrugated pipes, comprising a machine body 1, which supports various functional components and provides structural support for their coordinated operation. A fixed-length cutting assembly and a fixing assembly are installed inside the machine body 1. The fixing assembly is used to fix and constrain the corrugated pipe during the cutting process, preventing displacement due to cutting force and ensuring cutting accuracy. The fixed-length cutting assembly includes brackets 6, with multiple brackets 6 fixedly connected to one side inside the machine body 1. The brackets 6 are used to fix support columns 7 and fixed-length wheels 10, etc. Support columns 7 are fixedly connected to one side of each bracket 6, and rotating columns 8 are rotatably connected to one end of each support column 7. The rotating columns 8 can rotate freely around the support columns 7, coordinating with the conveying of the corrugated pipe. The system rotates to ensure smooth conveying. Fixed-length wheels 10 are installed between multiple supports 6. These wheels drive the corrugated pipe to convey a preset length. The conveying distance is controlled by the number of rotations, achieving a fixed-length function. A support assembly is installed on one side of each support 6. Multiple baffles 9 are fixedly connected to the outer side of the fixed-length wheels 10. These baffles 9 radially limit the corrugated pipe, preventing lateral deviation during conveying. Multiple guide posts 13 are fixedly connected to one side of the fixed-length wheels 10. These guide posts 13 are used to mount guide plates 15, allowing the guide plates 15 to rotate and adjust around the guide posts 13. Guide plates 15 are rotatably connected to the side walls of multiple guide posts 13. These guide plates 15 are used to mount the knife holder 17 and the cutting blade 16, and are supported by springs 14. To adapt to changes in the diameter of the corrugated pipe, springs 14 are installed between multiple guide plates 15. Each end of spring 14 is fixedly connected to one side of the guide plates 15. Springs 14 work elastically with the guide plates 15. When the corrugated pipe passes through, the guide plates 15, under the elastic force of springs 14, press tightly against the surface of the corrugated pipe, causing the cutting blade 16 to maintain proper contact with the corrugated pipe. A blade holder 17 is fixedly connected to one side of each guide plate 15 to hold the cutting blade 16. The cutting blade 16 is used to cut the corrugated pipe. Driven by the guide plates 15 and with the fixed-length conveying of the length-determining wheel 10, automatic fixed-length cutting of the corrugated pipe is achieved. The support assembly includes a base 11. One side is fixedly connected to one side of one of the brackets 6. The base 11 is used to fix the motor 12 and provide a mounting platform for the motor 12. The motor 12 is set on the top of the base 11. The output end of the motor 12 is fixedly connected to the inside of the fixed length wheel 10. The motor 12 serves as a power source to drive the fixed length wheel 10 to rotate. The rotation of the fixed length wheel 10 realizes the conveying of the corrugated pipe. Multiple rotating wheels 1 2 are rotatably connected inside the machine body 1. Belts 3 are set between the multiple rotating wheels 1 2. The rotating wheels 1 2 cooperate with the belts 3 for transmission. The rotation of the rotating wheels 1 2 drives the belts 3 to move, realizing the smooth conveying of the corrugated pipe in the machine body 1 and providing continuous processing material for the fixed length cutting component. Each of the multiple rotating wheels 1 2 has a rotating wheel column 5 fixedly connected to one end. The rotating wheel column 5 is used to connect the rotating wheels 1 2 and the rotating wheels 2 4.Rotor 2 (4) rotates synchronously with rotor 2 (2), and rotor 2 (4) is fixedly connected to the side walls of multiple rotor columns 5 to ensure the stability of the corrugated pipe conveying. Reference Figure 4 and Figure 5 The fixed-length cutting assembly includes a base plate 18 and a slide rail 25. One side of the base plate 18 is fixedly connected inside the machine body 1. The base plate 18 provides an installation foundation and load-bearing support for other components of the fixed-length cutting assembly. One side of the slide rail 25 is fixedly connected to one side of the base plate 18. The slide rail 25 guides the sliding direction of the sliding block 22, restricts the movement of the sliding block 22 along the track, and prevents the sliding block 22 from deviating or jamming during movement. Multiple bases 19 are fixedly connected to one side of the base plate 18. Connecting posts 21 are fixedly connected inside the multiple bases 19. The bases 19 are used to fix the connecting posts 21. 21 provides stable support, ensuring the structural stability of the connecting column 21 and guaranteeing the smooth sliding of the sliding block 22. Multiple sliding blocks 22 are slidably connected to the side wall of the connecting column 21. The connecting column 21 provides a sliding track for the sliding blocks 22, ensuring that the sliding blocks 22 can move smoothly in a straight line. Multiple springs 20 are provided on the side wall of the connecting column 21. One end of each spring 20 is fixedly connected to one side of the base 19, and the other end is fixedly connected to one side of the sliding block 22. The springs 20 cooperate with the sliding block 22 in elastic stretching motion. When the sliding block 22 is subjected to external force, the springs 20... The expansion and contraction of component 20 causes sliding block 22 to move adaptively along connecting post 21, achieving the effect of stretching the component. Multiple connecting posts 23 are fixedly connected inside each sliding block 22. Connecting posts 23 connect the sliding block 22 and the buffer block 24, transmitting the movement of the sliding block 22 to the buffer block 24 and providing mounting support for the buffer block 24. Multiple buffer blocks 24, made of rubber, are fixedly connected to the side walls of the connecting posts 23. These buffer blocks 24 contact the surface of the bellows, providing cushioning protection as the bellows passes through. Each sliding block 22 slides on one side. Connected inside the slide rail 25, the sliding block 22 slides in conjunction with the slide rail 25, further restricting the movement trajectory of the sliding block 22. This ensures stable movement of the sliding block 22 under the dual guidance of the connecting column 21 and the slide rail 25, preventing deflection during buffering and ensuring a uniform buffering effect on the corrugated pipe. The base plate 18 has a feeding groove 26 inside, which allows the corrugated pipe to pass through. The feeding groove 26 guides the conveying path of the corrugated pipe, preventing deviation during conveying and ensuring precise entry of the corrugated pipe into the cutting area, providing an accurate positional reference for fixed-length cutting. Working principle: The corrugated pipe enters the feeding trough 26 from the feed end and moves forward under the drive of the conveying system consisting of the first rotating wheel 2 and the belt 3. When the front end of the corrugated pipe contacts the baffle 9 of the fixed length wheel 10, the motor 12 drives the fixed length wheel 10 to rotate. The spring 14 at one end of the fixed length wheel 10 pushes out the guide plate 15 through elastic force. When the knife holder 17 fixedly connected to the top of the guide plate 15 rotates to the side wall of the rotating column 8, the rotating column 8 squeezes the knife holder 17 and drives the cutting knife 16 to cut. After the cutting is completed, the spring 14 resets the guide plate 15 and the cutting knife 16 retracts. At the same time, the sliding block 22 automatically adjusts the clamping force under the action of the second spring 20, pulls the sliding block 22 to slide in the slide rail 25, automatically center and clamp and fix it, ensuring the stable conveying of corrugated pipes of different diameters. The buffer block 24 absorbs the impact vibration during cutting. The whole process realizes the continuous operation of automatic fixed length, conveying and cutting.
