AI Technical Summary
Traditional barium wire feeding and cutting mechanisms have difficulty effectively constraining the transport trajectory of barium wires during high-speed feeding, resulting in uneven distribution of developing wires. During the cutting process, the barium wires are easily affected by shearing forces, causing retraction and unstable clamping. Furthermore, the clamps cannot adapt to different wire diameters, affecting production accuracy and efficiency.
The system employs a multi-stage guide cylinder combined with horizontal positioning wheels, along with movable grippers and photoelectric sensors, to achieve adaptive clamping and precise cutting of barium wire. Material sensors monitor the remaining material to ensure consistent feeding length.
It achieves high-precision feeding and adaptive clamping of barium wire, suppresses barium wire swaying, ensures cutting quality and production efficiency, reduces material waste, and improves equipment utilization.

TECHNICAL FIELD
[0001] The utility model relates to a medical product processing technical field, specifically is a barium line feeding cutting mechanism of nerve operation pad production. BACKGROUND
[0002] As the core functional component of high-end medical consumables such as nerve operation pad, the barium sulfate developing wire embedded in the barium line needs to maintain continuity and integrity in processing to meet the intraoperative X-ray developing positioning requirement. Barium line feeding is a key process in the production process, and its precision directly affects the developing performance and structural reliability of the product. The traditional barium line feeding cutting mechanism has the following technical bottlenecks:
[0003] The barium line has high flexibility and low tensile properties, and the combination of conventional guide cylinders and positioning wheels cannot effectively constrain its conveying trajectory. Especially at high speed, the barium line is prone to lateral swing or longitudinal distortion due to inertia, resulting in uneven distribution of developing wire, and even causing line body rupture. Although the passive guide wheel added in the prior art can alleviate the deviation, it lacks an active correction mechanism and cannot adapt to the tension fluctuation caused by the change of barium line cylinder diameter.
[0004] The traditional cutting mechanism mostly adopts single-knife vertical cutting mode, lacking dynamic clamping of the barium line. The barium line is prone to retraction under the action of shearing force at the moment of cutting, causing uneven cutting and exposure of developing wire. Some devices attempt to add fixed clamps, but the timing matching of clamping and cutting action is not good, and there is still a problem of barium line end rebound after the clamp is released, affecting the docking accuracy of the subsequent station.
[0005] Barium line feeding needs to be accurately synchronized with the rotating disc station, and the existing equipment relies on manual visual positioning, with poor consistency of feeding length (error often exceeds ±1.5mm). Although individual schemes introduce photoelectric sensors, the sensor layout is single and is easily disturbed by the semi-transparent properties of the barium line, with a high false trigger rate of 15%, resulting in production rhythm extension and material waste.
[0006] The barium line diameter is usually 0.8-2.0mm, and the contact surface hardness of the existing fixed clamp is too high, which easily crushes the surface fiber of the line body when clamping, damaging the internal developing wire structure. In addition, the opening and closing stroke of the clamp is fixed, which cannot be compatible with different line diameter specifications, and needs to be adjusted when replacing product models, reducing equipment utilization. SUMMARY

[0011] In the preferred scheme, a material sensor and two limit sensors are arranged on the barium line support below the barium line cylinder, and a photoelectric sensor is arranged on the barium line cutting mechanism.
[0012] The barium line output from the barium line cylinder passes through the material sensor and the two limit sensors.
[0013] The photoelectric sensor extends to the workstation rotary disc and is arranged downward, and the photoelectric sensor is used for monitoring the feeding position of the barium line.
