Description

Technical Field

[0001] The utility model belongs to the technical field of PTFE film production, and specifically relates to a hot pressing composite device for PTFE film production. Background Art

[0002] PTFE (polytetrafluoroethylene) membrane is a high-performance material that is widely used in many fields due to its unique chemical stability, high temperature resistance, wear resistance, low friction coefficient and other properties. With the continuous expansion and deepening of the application fields of PTFE membrane, the quality and performance requirements of PTFE membrane are also getting higher and higher. Therefore, in the production process of PTFE membrane, advanced hot pressing composite equipment is required to ensure the quality and performance of the membrane.

[0003] The prior art discloses a thermal composite device for curing polytetrafluoroethylene films (CN218197004U), the technical solution of which includes: a base body, a main frame, and a control box. Mounting seats are fixedly installed on both sides of the central position of the top of the base body, and an adjustment seat is movably installed on the top of the mounting seat. Hot pressing rollers are rotatably installed inside the mounting seat and the adjustment seat. A first hydraulic cylinder is fixedly installed on the main frame, and two sets of positioning frames are fixedly installed on the front of the main frame. A feed wheel is rotatably installed inside the positioning frame.

[0004] After searching, it was found that the existing technology lacks measures to fix the feed end and collect the discharge end when in use. This results in the inability to flexibly install materials at the feed end of the device when in use, and the inability to reel in the composite film at the discharge end, which requires manual cooperation, not only affecting the work process but also slowing down work efficiency; furthermore, since the device lacks cooling measures for the composite film, the composite film needs to be naturally cooled and shaped under pressure after it is fully fused.

[0030] like Figure 1 and Figure 2 As shown, the limiting frame 11 and the supporting frame 12 are similar in shape, and the limiting frame 11 and the supporting frame 12 are symmetrically arranged on the top surface of the workbench 10; Figure 1 and Figure 2As shown, three telescopic rods 14 are fixedly provided on one side of the support frame 12 close to the limit frame 11, and a limit plate 15 is fixedly provided on one end of the three telescopic rods 14 close to the limit frame 11, and the other end of the limit plate 15 is provided with an arc surface; Figure 1 、 Figure 2 and Figure 3 As shown, the support frame 12 is composed of a U-shaped frame and three long plates.
