Embodiment

[0036] see Figure 1 to Figure 3 , the backing tape supporting device for laying thermosetting composite prepreg tape in this embodiment includes a transmission mechanism, a pressure bonding mechanism, an automatic tensioning mechanism and a tension detection mechanism.

[0037]The transmission mechanism is used to support the backing belt, and one end of the backing belt 115 of the cotton canvas flat belt covered with heat-resistant rubber is sleeved on the backing belt driving wheel 114, and the backing belt driving wheel 114 is fixed on the transmission shaft 112, and Axial positioning is carried out by means of a circlip 113 . A timing pulley 109 is installed on the extended end of the transmission shaft 112 outside to provide power input. The two ends of the transmission shaft 112 are installed on the front support plate 101 and the rear support plate 108 through the front belt cover bearing 110 and the rear belt cover bearing 128 . In the process of unwinding and conve...

Abstract

The invention relates to a backing tape supporting device for laying a thermosetting composite material prepreg tape, and belongs to the technical field of advanced composite material automatic manufacturing device. The backing tape supporting device comprises a transmission mechanism, a pressing and sticking mechanism, an automatic tensioning mechanism and a tension force detection mechanism, wherein the transmission mechanism is provided with a driving wheel used for driving a backing tape and a driver used for driving the driving wheel to rotate, and is further provided with a heating unitused for preheating the backing tape; the pressing and sticking mechanism is used for pressing and sticking the prepreg tape in an unwinding conveying path on the backing tape, and automatically controlling the time point of pressing and sticking according to the requirement of the laying time period; the automatic tensioning mechanism is provided with a tensioning wheel which supports the backingtape together with the driving wheel, the driving wheel and the tensioning wheel are located at the upper end of the backing tape, and a pressing roller is arranged at the lower end of the backing tape; and the tension force detection mechanism is used for detecting the tension force of the backing tape so as to detect the tension force of the prepreg tape adhered to the backing tape. The prepregtape does not need to be supported by backing paper in the advancing process, so that a shearing mechanism is simplified.

Description

technical field [0001] The invention relates to the technical field of advanced composite material automatic manufacturing equipment, in particular to a backing tape support device for laying thermosetting composite material prepreg tape. Background technique [0002] Automatic tape laying technology is an automatic additive manufacturing technology that lays composite material prepreg tape on the mold. Equipment that completes the molding and manufacturing of composite components. [0003] Commonly used thermosetting composite materials are composite materials with thermosetting resin as the matrix and reinforcing fiber as the reinforcement. It has the advantages of high strength, high stiffness, and high temperature resistance. It has been widely used in the fields of aerospace and transportation. [0004] Thermosetting prepreg tape is the intermediate material for the preparation of composite structural parts. Whether it is wet-processed or downstream-processed, the ther...
