Description

Tension detection device

Technical Field

The utility model relates to the field of detection devices, in particular to a tension detection device.

Background

At present, a tension roller device is widely applied to production and processing of coiled materials, tension detection and control are also one of important links of a production process, and the quality of products is directly influenced. The tension sensor with reliable performance basically depends on import, and according to different application occasions and measuring ranges, the price of a single set is thousands to hundreds of thousands, the measuring range is increased, and the price is increased by times.

The coil tension detection device mainly comprises a roller, a bearing seat and a tension sensor (a pillow type or a flange type). The roller is mounted on a tension sensor through a bearing seat, and the tension sensor is required to bear the load generated by the tension of a material and the weight load of the roller. Therefore, the range of the tension sensor is necessarily selected according to the combined action load of the tension sensor and the roller, and particularly when the weight load of the roller is large, the range of the tension sensor is larger or more than the range required by the tension load of the material. This results in two disadvantages, namely, the high cost of the wide-range tension sensor, and the poor measurement accuracy of the tension sensor, especially in low tension control applications. Lightening the roll weight is a common solution today, mainly by reducing the roll size and using low density high modulus materials (such as carbon fiber). However, low density, high modulus materials are expensive and have limitations due to limited methods of reducing roll size to ensure rigidity and accuracy.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the utility model provides a tension detection device, which changes the structure of the traditional tension detection device to prevent the weight load of a roller from acting on a tension sensor, thereby reducing or eliminating the influence of the weight of the roller on the tension detection device, reducing the equipment cost and improving the detection and control precision of the tension.

Based on the above purpose, the utility model provides a tension detection device, which comprises a tension roller, a tension roller bearing seat, a tension sensor and a sliding rail, wherein the tension roller is installed or erected on the sliding rail through the tension roller bearing seat.

The tension roller is vertically arranged or erected on the sliding track through the tension roller bearing seat, the weight of the roller can act on the sliding track, and the measuring range of the tension sensor is only the resultant force of materials or the component force of the resultant force, so that a wide-range tension sensor together with the roller weight is not required to be selected, the cost is saved, and the precision error caused by the wide-range sensor is avoided.

Preferably, the sliding track is a linear guide rail, an air-float guide rail or a magnetic-levitation guide rail, and the influence of friction resistance on the precision of the tension sensor can be reduced by adopting the sliding track with a small friction coefficient, so that the precision of a measuring result is improved.

Furthermore, the tension sensor is tightly attached to one side of the tension roller bearing seat, so that the accuracy of the tension test is kept.

Preferably, the tension sensor is mounted on the sensor fixing seat in close contact with one side of the tension roller bearing seat.

Further, a tension roller bearing seat calibrating device is arranged on the other side of the tension roller bearing seat, preferably, the tension roller bearing seat calibrating device is a tension roller bearing seat jackscrew and is used for ensuring the resetting of the roller and calibrating the tension sensor.

According to the tension detection device, the tension roller is mounted or erected on the sliding rail, so that the weight of the roller acts on the sliding rail, and the range of the tension sensor is only the resultant force of materials or the component force of the resultant force, so that a wide-range tension sensor together with the weight of the roller is not required to be selected, the cost is saved, the detection precision is improved, the structure is simple, and the realization is easy.
