Description

Melt and spout cloth roll diameter on-line measuring device

Technical Field

The utility model relates to an online detection device for the roll diameter of melt-blown fabric, and belongs to the technical field of textiles.

Background

The demand and attention of the mask reach unprecedented levels since new coronary epidemics. The core functional layer of the mask is a melt-blown non-woven material positioned in the core layer, and various enterprises make changes to produce the melt-blown non-woven material. At present, most slitting and winding equipment adopts a fixed-length system, namely, the fixed-length equipment stops and rolls down after the requirement is met, but instability exists in the production process of melt-blown fabric, the fluffiness of the fabric surface and the like can be influenced, and the same fixed length exists and the roll diameters are different. An operator needs to monitor in real time in the operation process of the equipment and cannot accurately measure, manpower is wasted, the diameter of the coil is too large or too small, and large and small coils are generated. Customers generally have requirements for the diameter range, and the product is unqualified due to the undersize diameter, and the raw material is wasted. At present, the most accurate diameter measuring method of a machine needs manual measuring by a ruler after the coil is dropped. If the diameter is too small, it will cause waste. Too large diameter also consumes manpower to remove the outer layer of the cloth roll and also causes the generation of waste melt-blown cloth. Therefore, the utility model avoids producing the coil which does not meet the diameter requirement, and stops when the coil diameter meets the requirement, thereby reducing the waste of manpower and material resources.

SUMMERY OF THE UTILITY MODEL

According to the defects in the prior art, the technical problems to be solved by the utility model are as follows: the utility model provides a melt-blown fabric book footpath on-line measuring device can real-time detection melt-blown fabric book footpath to guarantee the uniformity of outward appearance, avoid because of the unqualified product that the yardage roll diameter undersize or too big caused.

The utility model relates to an online detection device for the diameter of a melt-blown fabric roll, which comprises a winding roll, wherein the winding roll is horizontal and rotatable, two ends of the winding roll are arranged on a rack through a bearing with a seat, a roll shaft of the winding roll is connected with a driving motor through a worm gear reducer, a distance measuring sensor is arranged above the winding roll and is connected with a controller, and the controller is connected with the driving motor.

The distance measuring sensor is used for measuring the distance between the distance measuring sensor and the rolling cloth, so that the rolling is carried out in a proper rolling diameter, and the generation of unqualified products is reduced.

The driving motor is arranged at one end of the winding roller and used for driving the winding roller.

In order to ensure the accuracy of the measuring result, the ray of the distance measuring sensor is vertical to the tangent plane of the winding roller.

Furthermore, the distance measuring sensor is arranged on the portal frame in a sliding mode through the sliding block, can move left and right, and is high in practicability.

Furthermore, a lifting cylinder is arranged between the sliding block and the distance measuring sensor, so that the adaptability of the device is further enhanced.

The distance measuring sensors are arranged in two groups, and the two groups of distance measuring sensors are identical in height and are arranged along the axial direction of the winding roller. Two sets of sensor measurements may be averaged to reduce error.

Preferably, the distance measuring sensor is a laser distance measuring sensor. Due to the non-planar structure of the roll surface, the measurement accuracy of the ultrasonic sensor is lower than that of a laser sensor. Compared with an ultrasonic distance measuring sensor, the ultrasonic distance measuring sensor has high measuring precision; the response speed is high; the 905 nanometer laser has no harm to human eyes. And the volume is small, and the installation is convenient.

Compared with the prior art, the utility model has the beneficial effects that:

the online detection device for the roll diameter of the meltblown fabric is applied to online detection of the diameter of the roll in the winding process after the meltblown fabric is cut, and can detect the diameter of the roll in real time so as to ensure the consistency of the appearance and reduce unqualified products caused by over-small or over-large diameter. The convenient roll that falls in suitable book footpath reduces the waste of manpower and material resources.
