Abstract
The utility model discloses a yarn tension sensor, comprising an elongated ceramic bottom plate and an elongated ceramic elastic sheet which correspond to each other up to down. A fixed end of the ceramic elastic sheet is fixed on a projected fixed base at one end of the ceramic bottom plate, a free end of the ceramic elastic sheet is provided with a yarn ceramic supporting component and magnetic steel, a magnetic field inductor is arranged at the end of the ceramic bottom plate without the fixed base corresponding to the magnetic steel, and the magnetic field inductor comprises a Hall magneto-dependent sensor, a programmable controller and a signal processing circuit. The yarn tension sensor can convert magnitude of detected yarns into variation of magnetic field strength, converts magnetic field strength signals into electric signals via the magnetic field inductor, and can perform automatic on-line detection for variation of tension of the detected yarns accurately at real time. Structural components of the yarn tension sensor are made of ceramic materials, thereby preventing fatigue of metal materials interfering electromagnetic signals and environmental temperature. The electronic elements of the yarn tension sensor do not contact with yarns directly, and then the yarn tension sensor is adaptable to severe environments and easy to clean and maintain.
Description
Technical field
The utility model belongs to technical field of textile machine, especially a kind of yarn tension sensor that is used to detect textile yarn tension force.
Background technology
In various textile machines, yarn tension is detected, thereby realize that robotization control is the gordian technique of textile machine.Yarn tension detects, and adopts usually the small simulation millivolt voltage signal of yarn is amplified to several thousand times to it by hardware circuit, and making its output voltage by shaping circuit again is the standard signal of 0～5V.This method circuit complexity, the cost height, temperature control is poor, and consistance is difficult to guarantee, the feasible true cause that can't popularize use at present in field of textile machinery.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, provide a kind of simple in structure, antijamming capability is strong, and is insensitive to temperature variation, the easy yarn tension sensor of safeguarding.
The purpose of this utility model is achieved in that a kind of yarn tension sensor, it is characterized in that: it comprises corresponding strip ceramic bottom board and strip pottery shell fragment up and down, the stiff end of pottery shell fragment is fixed on the holder of an end projection of ceramic bottom board, the free end of pottery shell fragment is equipped with yarn ceramic support parts and magnet steel, magnetic sensors is installed in the corresponding position of the on-fixed seat end of ceramic bottom board and magnet steel, and magnetic sensors comprises hall magnetic sensor, Programmable Logic Controller and signal processing circuit.
The on-fixed seat end of described ceramic bottom board has two limited blocks that prevent ceramic shell fragment transverse shakiness that raise up.
The utlity model has following advantage: it comprises strip ceramic bottom board and the strip pottery shell fragment that an end is fixed together, on the ceramic shell fragment of the other end, yarn ceramic support parts and magnet steel are arranged, the ceramic bottom board of the other end is installed magnetic sensors, this magnetic sensors comprises hall magnetic sensor and Programmable Logic Controller, it can be transformed into the tension variation of tested yarn the corresponding displacement of flexure strip, this displacement is corresponding with change of magnetic field strength, magnetic sensors is converted to electric signal to the magnetic field intensity signal of sensing, thus can be accurate, in real time tested yarn tension is changed and carry out online automatic detection.This yarn tension sensor can be revised the discreteness of each sensor by programming, and the electric signal of each sensor that makes guarantees that fully one is straightforward, detects thereby be implemented in line tension.Its structural element adopts ceramic material, has avoided the interference of metal material fatigue to electromagnetic signal and environment temperature.It directly contacts with yarn without any electronic component, is applicable to rugged environment, easy to clean, easy care.
