Full-automatic datamation constant-tension tailing-free automatic roll changing and unwinding control system

Abstract

The invention relates to the field of elastic material conveying equipment, in particular to a full-automatic datamation constant-tension tailing-free automatic roll changing and unwinding control system which comprises a rack, a plurality of feeding stations are arranged on the rack in a stacked mode, and each feeding station is provided with two symmetrically-arranged material hanging frames used for containing material rolls. In the feeding process of rubber bands, each feeding station is sequentially provided with a yarn baffle, a first-stage buffer mechanism, a second-stage buffer mechanism, a datamation elastic force control mechanism and a plurality of guide wheels used for guiding all parts, wherein a yarn outlet guide wheel set used for collecting the rubber bands conveyed on all the feeding stations is arranged at the portion, located at the conveying rear end of the datamation elastic force control mechanism, of the rack. Each yarn baffle is arranged on the symmetrical center line of the corresponding two material hanging frames, a ceramic hole for the rubber bands to penetrate through is formed in the center of each yarn baffle, and when material rolls are arranged on the material hanging frames, the axial centers of the material rolls are arranged right opposite to the ceramic holes. According to the full-automatic datamation constant-tension tailing-free automatic roll changing and unwinding control system, the problem that the tension cannot be kept constant when an existing elastic piece is fed and unwound is solved.

Description

technical field [0001] The invention relates to the field of elastic material conveying equipment, in particular to a fully automatic data-based constant tension and tailless automatic roll changing and unwinding control system. Background technique [0002] In the production of hygienic products such as diapers, pull-up pants and other products, elastic parts such as elastic bands are often needed, and the production equipment needs to have the ability to stably transport elastic parts during the production process, as shown in Chinese patent CN 203998422 U The basic structure of the existing feeding device is improved. The elastic tension control feeding device used in the production of sanitary products includes a frame body, and a plurality of feeding rollers are arranged on the frame body. The feeding rollers are connected by rubber band transmission. There is also a tension control device on the frame body. The tension control device is located between the feeding roll...
