Polytetrafluoroethylene winding and demolding integrated machine

Abstract

The invention discloses a polytetrafluoroethylene winding and demolding integrated machine. The machine comprises an equipment supporting frame and a polytetrafluoroethylene pipe mold, and is characterized in that a driving device for driving the polytetrafluoroethylene pipe mold to circumferentially rotate relative to the equipment supporting frame is arranged on the equipment supporting frame, and a pneumatic rolling mechanism corresponding to the polytetrafluoroethylene pipe mold in the circumferential direction is further arranged on the equipment supporting frame; the pneumatic rolling mechanism comprises a walking table, a rolling wheel and an air pump, the walking table axially moves relative to the polytetrafluoroethylene pipe mold, the air pump is fixed on the walking table and pushes the rolling wheel to abut against the polytetrafluoroethylene pipe mold, and the extension direction of the central axis of the rolling wheel is parallel to the center of the polytetrafluoroethylene pipe mold. According to the maching, the rolling mode between the rolling wheel and the PTFE pipe is thoroughly changed, so that the finished PTFE pipe with uniform pressure can be directly used, and the problems that the surface of a product produced in the prior art presents tiny edges and corners, and later machining is needed because the product cannot be directly demolded and disappeared are solved; according to the equipment scheme, working procedures, site occupation and cost expenditure are saved.

Description

technical field [0001] The invention relates to the technical field of PTFE tube manufacturing equipment, in particular to a PTFE winding and demoulding integrated machine. Background technique [0002] At present, in the molding and manufacturing process of PTFE tubes, it is generally used to sinter the PTFE tubes on the mold shaft, and then take off the PTFE tubes after cooling. At present, this kind of demoulding method generally adopts manual methods such as hard pulling for demoulding. The existing technology demoulding is more based on this soil method and is carried out by mechanical instead of manual. Carry out axial fixation, manually drive its circumferential rotation, and then control the rolling wheel to move along its axial direction, and the rolling wheel exerts pressure on the outer wall, and rotates and switches the PTFE tube for each axial stroke of the PTFE tube mold. The mold is repeated at an angle, so that the diameter of the PTFE tube becomes larger an...

Problems solved by technology

[0003] However, in this demoulding method, after the tetrafluoro tube is removed, the tetrafluoro tube needs to be processed, because the outer surface of the demoulding product of this equipment is composed of countless planes, as shown in the attached manual image 3 As shown in the schematic diagram of a, this also leads to the fact that the tetrafluoro tube made in this way needs to be processed into a circular shape in the later stage, and the processing will inevitably increase the process and generate waste.
