A non-woven fabric parent roll unwinding device

Abstract

The invention relates to the field of nonwoven fabric processing devices, in particular to a nonwoven fabric mother roll unrolling device. The nonwoven fabric mother roll unrolling device is provided with a bottom beam. A left side plate and a right side plate are arranged at the two ends of the bottom beam correspondingly. Two supporting plates are symmetrically arranged on the two side plates. Each supporting plate is provided with a sliding bearing. An air expansion shaft is arranged between the sliding bearings on the two supporting plates and provided with a nonwoven fabric mother roll. The supporting plates are provided with a tension control device controlling the unrolling speed of the nonwoven fabric mother roll, and an automation deviation correcting device controlling axial deviation of the nonwoven fabric mother roll. The bottom beam is further provided with two stand columns symmetrically arranged left and right, a cross rod is connected between the two stand columns, and the cross rod is provided with a glue pasting device. By means of the nonwoven fabric mother roll unrolling device, the uniform unrolling speed can be kept, the automatic deviation correcting function is achieved, it can be kept that in the nonwoven fabric mother roll cloth releasing process, the contact part of a double faced adhesive tape mother roll and the nonwoven fabric mother roll is smooth and free of wrinkles, and good popularization prospects are achieved.

Description

technical field [0001] The invention relates to the field of non-woven fabric processing devices, in particular to a non-woven master roll unwinding device. Background technique [0002] In actual production, the non-woven master roll needs to be uncoiled, conveyed at a fixed distance, sealed, cut and other subsequent processing. The unwinding process is to place the non-woven master roll on a support with a roller, and the non-woven master roll Unwind and convey to the rear end through the traction conveying device. [0003] In the prior art, the traction conveying device is generally provided with a pair of rollers, which are rotated under the drive of the motor to pull the coiled material for backward conveyance. The conveying speed is uniform, and the length of the coil conveyed per unit time is kept consistent to meet the processing requirements in the subsequent process. For example, the coil is required to be cut at a fixed distance in the cutting process. [0004] ...

Problems solved by technology

[0004] However, during the winding process, manufacturers of non-woven fabric parent rolls often have inconsistent tightness on the parent rolls due to equipment reasons, resulting in inconsistent lengths of coils delivered by the traction device per unit time during the unwinding process, resulting in The fixed distance cutting is unstable, which seriously affects the product quality of the subsequent process

[0005] In addition, when it is necessary to make multi-layer non-woven fabric products, it is usually necessary to apply glue or double-sided tape between the upper and lower layers of non-woven fabrics. In the traditional process, it is applied and pasted manually or with hand-held auxiliary tools, which is extremely difficult. It is easy to cause the edge of the upper and lower non-woven fabrics to be difficult to align or the surface of the non-woven fabric to have wrinkles, which seriously affects the quality of the finished product
