Abstract

The invention relates to a PTFE (Polytetrafluoroethylene) unsintered tape forming device and belongs to the technical field of manufacturing of PTFE mechanical equipment. The PTFE unsintered tape forming device is formed in a mode that an upper body is connected with a lower body through a bolt. After the upper body and the lower body are connected, a cavity body is formed. A cylindrical opening is formed at one end of the cavity body. A straight line opening is formed at the other end of the cavity body. Flow stop blocks are arranged on the inner lateral surfaces of both the upper body and the lower body. The flow stop blocks are arranged at the middle positions in the cavity body, which are close to the cylindrical opening. The occurrence of the PTFE unsintered tape forming device can completely change the preparation mode of a PTFE unsintered tape and can also change the microstructure of the PTFE unsintered tape so that the PTFE unsintered tape is easier to stretch.

Description

technical field [0001] The invention relates to a forming device, in particular to a polytetrafluoroethylene raw material belt forming device. It belongs to the technical field of mechanical equipment manufacturing of polytetrafluoroethylene. Background technique [0002] The stretching method is the most mature in the prior art for preparing PTFE fiber film, and the direct object of stretching is PTFE raw material tape. As described in the Chinese invention patent with the application number of 200610026648.1, a method for manufacturing polytetrafluoroethylene long fiber, which selects 100% polytetrafluoroethylene as the raw material, uses a screw extruder, a calender, a stretching machine, Processing equipment such as heating and stretching machines, slitting machines, twisting machines, extrusion stretching machines, winding machines, etc., are manufactured by the following methods: First, put polytetrafluoroethylene in a screw extruder for extrusion, and screw extru...
