Embodiment 1

[0040] Such as figure 1 , 2 , 3, 4, and 5, a full-automatic PTFE film / fiber stretching sintering machine includes a casing 2 with a sealed stretching sintering chamber 1, and one for stretching and sintering in the stretching sintering chamber 1. The heated temperature control part 3, the temperature control part 3 can adopt electric heating tubes or other electric heating elements commonly used at present, and the working temperature environment in the stretching sintering chamber 1 is 220-240°C. A door body for sealing the stretch sintering chamber 1 is provided on the box body 2 , and the door body is not shown in the accompanying drawings in order to clearly illustrate the technical solution of the present application. One side of the box body 2 is provided with an unwinding device 5 for conveying the PTFE film / fiber 4 into the stretching sintering chamber 1, and the other side is provided with a winding device 5 for stretching and sintering the PTFE film / fiber 4 after se...

Embodiment 2

[0053] The same parts of this embodiment and Embodiment 1 will not be repeated. The difference is that in order to realize the automatic operation of the equipment, this embodiment adopts a fully automatic signal control mode. Specifically, the broken end connection system includes a controller. Either side of the unwinding device 5 or the winding device 6 is provided with a detection element for detecting a tension change when the PTFE film / fiber 4 breaks, and the detection element detects a tension change and sends a detection signal to the controller, and the controller After receiving the detection signal, send the signal for driving the stretching roller assembly 7 to stop rotating to the power mechanism, and send the signal for driving the lower stretching roller 9 to rise to the second power mechanism 15, and send the signal for driving the clamping and pulling Pull the broken PTFE film / fiber 4 from the unwinding end 23 through the upper stretching roller 8 and the lower...

Abstract

The invention discloses a full-automatic PTFE film / fiber stretching and sintering machine. The full-automatic PTFE film / fiber stretching and sintering machine comprises a box body with a sealed stretching and sintering chamber and a temperature control part, an unwinding device is arranged on one side of the box body, a winding device is arranged on the other side of the box body, in the conveyingdirection of PTFE films / fibers, a plurality of stretching roller assemblies for carrying out constant-force stretching treatment on the PTFE films / fibers and a power mechanism for driving the stretching roller assemblies to rotate at a constant speed are arranged in the stretching and sintering chamber; the full-automatic PTFE film / fiber stretching and sintering machine further comprises a brokenend connecting system which pulls the broken PTFE films / fibers to be sequentially wound on the stretching roller assemblies in a staggered mode and is connected with the winding device when the PTFEfilms / fibers in the stretching and sintering chamber are broken. The invention further discloses a method for stretching and sintering the stretching and sintering machine. By arranging a traction device and a lifting device, the PTFE films / fibers can be sequentially wound on the stretching roller assemblies in a staggered mode again without opening a door, and the problem of breakage of the PTFEfilms / fibers in the stretching and sintering process can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of textile equipment, and in particular relates to a fully automatic PTFE film / fiber stretching and sintering machine and a stretching and sintering method. Background technique [0002] Polytetrafluoroethylene (PTFE) is a polymer material polymerized from tetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealing, high lubrication, non-stickiness, electrical insulation and good aging resistance. And it is physiologically inert and non-toxic. Therefore, PTFE is widely used in national defense, atomic energy, petroleum, radio, electric machinery, chemical industry and other fields. Polytetrafluoroethylene polymer materials can be used to prepare fiber membranes or fibers. Different applications put forward different requirements for fiber membranes, including membrane pore size, membrane structure, membrane flux, membrane fouling, membrane strength, corrosion resistance, and ...
