Description

A real-time detection device for cable unevenness

technical field

The invention relates to the technical field of wire and cable production, in particular to a real-time detection device for cable unevenness.

Background technique

At present, in the production process of wires and cables, there are phenomena of poor outer diameter of wires and cables, such as bulges, knots, lack of glue, etc. In order to ensure product quality, wires and cables need to be tested. There are mainly two types of existing testing instruments, one One is to use a laser caliper for concave-convex detection, which is costly; the other is to detect mechanically, but due to insufficient mechanical precision, false alarms and inaccurate detection are prone to occur.

Contents of the invention

The technical problem to be solved by the present invention is to provide a real-time detection device for cable unevenness, which can accurately and stably detect the bad phenomenon of the outer diameter of the cable and provide real-time feedback.

The above-mentioned technical problems to be solved by the present invention are realized through the following technical solutions:

A real-time detection device for cable unevenness, which includes a fixed seat and a movable seat, the movable seat is movably installed above the fixed seat, and there is a gap between the fixed seat, and a liquid squeezer is arranged above the movable seat device, a thin pipe is connected above the liquid extruding device, and a detection device is fixed on the thin pipe.

Preferably, the sides of the fixed seat and the movable seat close to the gap are respectively rotatably connected with rollers. The design of the roller enables the cable to move more smoothly, and can accurately detect changes in the diameter of the cable, thereby improving detection accuracy.

Preferably, the liquid extrusion device is a water injection bag, a fixed surface is provided above the movable seat, the water injection bag is fixed between the movable seat and the fixed surface, and the thin pipe passes through the fixed surface and connects with the water injection bag connected.

Further preferably, the water injection bag is made of elastic material. The choice of elastic material enables the water injection bag to reset automatically. When the radius of the cable becomes smaller or sags, the water injection bag can also reset to change the liquid level of the liquid in the thin pipe to ensure the accuracy of detection.

Further preferably, the water injection bag is made of silica gel. The water injection bag made of silica gel has good elastic reset performance.

Preferably, the detection device includes an induction float and a detection element, the induction float is placed in the thin pipe, and the detection element is fixed on the thin pipe. The induction float rises and falls with the change of the liquid level, and when the induction float exceeds the detection range of the detection element, the detection element is triggered to realize the function of real-time detection of the cable diameter.

Further preferably, the inspection element is electrically connected with an alarm device. The alarm device can provide real-time feedback on the abnormality of the outer diameter of the cable.

Preferably, the upper end of the thin pipe is a large pipe diameter structure. This structural design prevents the liquid from overflowing and ensures the accuracy of detection.

Beneficial effects: after adopting the structure described in the present invention, the change in cable diameter drives the movable seat to press the water injection bag, so that the liquid level on the thin pipe has a significant change, and the diameter change of the cable is effectively amplified. The detection accuracy is improved; the mutual cooperation between the detection element and the induction float realizes the function of real-time detection and feedback of the cable, and when the cable specification is changed, the operation of calibrating the detection element is simple and the time is short; further, the elastic material is used The memory water injection bag can automatically restore the volume of the container to match the change of the liquid level, and can effectively feed back the outer diameter information of the cable in real time.
