Casing online bulge monitoring device

Abstract

The invention relates to a sleeve on-line swelling monitoring device which comprises a support (1), a fixed board (4) is installed on the support (1), and a distance regulation device (18), a pendulum block device (16) and a detection device (17) are installed on the fixed board (4). The sleeve on-line swelling monitoring device meets requirements of optical cable production processes, the pendulum block device and an alarm device are used creatively, operation is simple, convenient, safe and reliable, sleeve swelling can be monitored in real time, sleeves are located accurately, and no damage to the sleeves is caused; and meanwhile, an eccentric distance regulation system is used, a gap between a swelling test piece and a regulation block can be conveniently regulated, and therefore, the sleeve on-line swelling monitoring device is suitable for sleeves with different diameters.

Description

technical field [0001] The invention relates to an online bulge monitoring device for casing. Background technique [0002] In the production and manufacturing process of communication optical cables, the bulges produced in the secondary coating process, that is, the bulges produced on the surface of the casing, cannot be effectively monitored, so they are easy to be broken during the next process (cable formation), resulting in greater losses. At present, most manufacturers adopt the Huff mode overmolding method to monitor the bulges, which has the following defects, which leads to many bulges not being detected or mistaken for bulges: [0003] 1. Due to the high speed of plastic sleeve production, the speed can reach 300m / min, the friction between the casing and the half mold will easily take away the upper half mold, and there are cases of false alarms. However, the pressure between the two half molds should not be too large, which may break or damage the casing; [000...

AI Technical Summary

Problems solved by technology

However, the pressure between the two half molds should not be too large, which may break or damage the casing;

[0004] 2. Since the half mold is placed in the water tank, when the production speed of the casing is fast, the water flow is also very fast, and the half mold is often washed away. It is difficult to confirm whether it is due to the water flow or it really exists. Drum kit

However, if the half mold is not placed in the sink, when a bulge appears, the upper half mold will fly out, damage the equipment and even affect the safety of life, which is absolutely not allowed;

[0005] 3. When the casing bulge appeared, the Huff mold was lifted and dropped, so the bulge was not detected;

[0006] 4. Because the half mold is placed in the water tank, it is impossible to monitor it all the time when the operator is nervous, and the exact position of the casing bulge cannot be judged
