Description

Technical Field

[0001] This utility model relates to the field of catheter core insertion technology, and in particular to a catheter core insertion structure compatible with multiple lengths. Background Technology

[0002] With the increasing demand for catheters in the medical and industrial sectors, catheter core insertion technology is particularly important in ensuring the proper functioning of the catheter's internal structure. Especially when applied to catheters of different lengths and types, the core insertion device needs to be flexible and adaptable to ensure efficient and accurate insertion of the inner core into the catheter during the manufacturing process. Therefore, developing a catheter core insertion structure compatible with multiple lengths not only improves production efficiency but also enhances the practicality and convenience of the equipment, becoming a key direction for industry development.

[0003] Current catheter puncture devices typically use mechanical pressing or clamping methods to secure the catheter, and a transmission system to push the mandrel into the catheter. Traditional devices generally use a combination of motor drive, pneumatic components, and simple clamps to perform the puncture process. These devices usually have defined fixing points when processing catheters, relying on position control and sensors to ensure alignment between the catheter and the mandrel. This conventional design is suitable for standard-length catheters, but it is often difficult to adapt flexibly to catheters of different sizes or lengths.

[0004] However, existing catheter core insertion structures have significant limitations when adapting to catheters of different lengths. Traditional devices are typically fixed to a specific size, failing to meet diverse catheter requirements. This leads to problems such as inaccurate core insertion, wobbling, or misalignment during use, especially with shorter catheters, easily causing core insertion failure or low efficiency. Furthermore, overly complex limiting and adjustment structures increase operational difficulty and maintenance costs. To address these issues, there is an urgent need to develop a novel catheter core insertion structure compatible with multiple lengths, providing a more flexible and efficient core insertion solution to meet ever-changing production demands. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a catheter core insertion structure compatible with multiple lengths, aiming to improve the problem that the catheter core insertion structure cannot meet the needs of catheters of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a core-passing structure compatible with multiple lengths of conduit, including a base, an inner core hopper and a conduit hopper fixedly connected to the top of the base, a limit component provided inside the inner core hopper and the conduit hopper, an output component provided inside the inner core hopper and the conduit hopper, a metering component provided on the top of the base, a core-passing component provided on one side of the base, and a driving component provided on the top of the base;

[0007] The core-piercing assembly includes a second bracket, which is disposed on one side of the base. An electric slide rail is fixedly connected to the outer wall of the second bracket. A second limiting rod is fixedly connected to one side of the base. A core-piercing rod is fixedly connected to the output end of the electric slide rail. The bottom of the core-piercing rod is slidably connected to the outer wall of the second limiting rod.

[0008] As a further description of the above technical solution:

[0009] The output component includes a motor, the outer wall of which is fixedly connected to one side of the guide hopper, and a rubber shaft is fixedly connected to the output end of the motor.

[0010] As a further description of the above technical solution:

[0011] The quantitative component includes a catheter positioning roller, which is rotatably connected to the top of the base.

[0012] As a further description of the above technical solution:

[0013] The drive assembly includes a second motor, the outer wall of which is fixedly connected to the top of the base, and a pulley is fixedly connected to the output end of the second motor.

[0014] As a further description of the above technical solution:

[0015] One end of the guide positioning roller is fixedly connected to a second pulley, and a belt is provided between the second pulley and the first pulley.

[0016] As a further description of the above technical solution:

[0017] The limiting component includes a limiting rod, both ends of which are fixedly connected to the top of the inner core hopper and the guide hopper, and a partition is slidably connected to the outer wall of the limiting rod.

[0018] As a further description of the above technical solution:

[0019] A bracket is fixedly connected to one side of the inner core hopper, and an electric push rod is fixedly connected to the top of the bracket. A limit plate is fixedly connected to the output end of the electric push rod.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the positioning roller first enables the guide tube material to be discharged quantitatively. Then, the output end of the electric push rod extends out and the limiting plate is embedded in the guide tube positioning roller to limit the guide tube. During the core-piercing operation, the output end of the electric slide rail drives the core-piercing rod to move and push the guide tube to one side, so that the inner core is embedded in the guide tube. This achieves the effect of adapting to the core-piercing of guide tubes of various lengths, solves the problem that the core-piercing structure of the guide tube cannot meet the needs of guide tubes of different sizes, and improves the practicality of the core-piercing structure of the guide tube.

[0022] 2. In this utility model, when adjusting the position of the partition for inner cores of different lengths of guide tubes, the partition is limited by a limiting rod within the inner core hopper and the guide tube hopper, which facilitates the adjustment of the partition and solves the problem that shorter guide tubes are prone to shaking and misalignment when limiting guide tubes of different lengths, thus improving the convenience of the guide tube core insertion structure.

[0031] 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.

[0032] Reference Figures 1-6This utility model provides an embodiment of a core-passing structure compatible with multiple lengths of conduit, including a base 1. The base 1 serves as the supporting foundation of the entire device, used to support and fix other functional components. An inner core hopper 2 and a conduit hopper 3 are fixedly connected to the top of the base 1. The inner core hopper 2 is used to store the inner core material to be used, and the conduit hopper 3 is used to store the conduit material to be processed. Both the inner core hopper 2 and the conduit hopper 3 are equipped with limiting components to constrain and position the inner core and conduit during material storage and output, preventing the material from shifting during use. Both the inner core hopper 2 and the conduit hopper 3 are equipped with output components to orient the material stored in the hopper, ensuring that the material can smoothly enter the subsequent process. A metering component is provided on the top of the base 1 to limit the length of the conduit material, so as to achieve compatibility with the processing of conduits of different lengths. A core-passing component is provided on one side of the base 1 to pass the inner core into the conduit, completing the core-passing operation. A drive component is provided on the top of the base 1 to provide power to drive the metering component and related mechanisms. The core-piercing assembly includes a second bracket 16, which is located on one side of the base 1 and serves to fix and support the core-piercing mechanism. An electric slide rail 18 is fixedly connected to the outer wall of the second bracket 16, providing linear drive to drive the core-piercing rod in reciprocating motion. A limit rod 17 is fixedly connected to one side of the base 1, guiding and constraining the movement of the core-piercing rod 19. The output end of the electric slide rail 18 is fixedly connected to the core-piercing rod 19, which acts as a direct actuator, its bottom slidably connected to the outer wall of the limit rod 17, and is driven by the electric slide rail 18 to push the inner core. The output assembly includes a first motor 6, whose outer wall is fixedly connected to one side of the guide tube hopper 3. The first motor 6 serves as a power source to drive the guide tube output. A rubber shaft 7 is fixedly connected to the output end of the first motor 6, which outputs the guide tube material through contact with the guide tube, ensuring continuous delivery of the guide tube. The metering component includes a guide tube positioning roller 12, which is rotatably connected to the top of the base 1. The roller 12 achieves guide tube feeding and positioning through frictional contact with the guide tube surface. The driving component includes a second motor 8, whose outer wall is fixedly connected to the top of the base 1, serving as the power source for driving the guide tube positioning roller 12. A pulley 9 is fixedly connected to the output end of the second motor 8, and a second pulley 10 is fixedly connected to one end of the guide tube positioning roller 12. A belt 11 is provided between the second pulley 10 and the first pulley 9, enabling transmission between the pulleys and allowing the guide tube positioning roller 12 to rotate with the second motor 8, thereby achieving guide tube transmission. The limiting component includes a limiting rod 4, both ends of which are fixedly connected to the top of the inner core hopper 2 and the guide tube hopper 3. A partition 5 is slidably connected to the outer wall of the limiting rod 4. The partition 5 slides on the limiting rod 4 to limit and separate the materials inside the inner core hopper 2 and the guide tube hopper 3, preventing material from scattering within the hoppers.A bracket 13 is fixedly connected to one side of the inner core hopper 2. An electric push rod 14 is fixedly connected to the top of the bracket 13. The electric push rod 14 is used to drive the limit plate to move up and down. A limit plate 15 is fixedly connected to the output end of the electric push rod 14. The limit plate 15, driven by the electric push rod 14, is used to press and limit the inner core material, ensuring the stability and accuracy of the inner core during the output process. The overall structure is supported by the base 1. The components cooperate with each other to realize the automatic quantitative, conveying, and core insertion operations of the guide tube and the inner core, thus accommodating the core insertion needs of guide tubes of various lengths.

[0033] Working principle: When using this multi-length compatible conduit core-piercing structure, the inner core material is first stored in the inner core hopper 2, and the conduit material is stored in the conduit hopper 3. When it is necessary to adjust the position of the partition 5 for conduit cores of different lengths, the partition 5 is limited in the inner core hopper 2 and the conduit hopper 3 by the limiting rod 4. Then, during the tube-piercing process, the output end of the motor 6 drives the rubber shaft 7 to rotate, conveying the material inside the inner core hopper 2 and the conduit hopper 3 to the groove on the conduit positioning roller 12. At the same time, the output end of the motor 8 drives the pulley 9 to rotate, and the pulley 9 drives the pulley 10 to rotate through the belt 11. Then, the pulley 10 drives the conduit positioning roller 12 to allow the conduit material to be discharged quantitatively. Then, the output end of the electric push rod 14 extends out of the limiting plate 15 and embeds into the conduit positioning roller 12 to limit the conduit. During the core-piercing operation, the output end of the electric slide rail 18 drives the core-piercing rod 19 to move and push the conduit to one side, so that the inner core is embedded inside the conduit.
