Description

Technical Field

[0001] This utility model relates to the field of PTFE membrane filter media technology, and in particular to electrostatic hot pressing equipment for PTFE membrane filter media. Background Technology

[0002] PTFE-coated filter media is a high-performance filter material, mainly consisting of a PTFE fiber mesh layer and a PTFE fiber membrane layer on top of it. This two-layer structure achieves effective dust filtration and interception. Furthermore, existing PTFE-coated filter media typically incorporate a high-temperature cotton layer and / or a wire reinforcement layer to cope with various filtration environments. The production process of PTFE-coated filter media requires electrostatic hot-pressing equipment for hot pressing. However, some current electrostatic hot-pressing equipment for PTFE-coated filter media lacks preheating capabilities, which is inconvenient for subsequent hot-pressing processes. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an electrostatic hot-pressing coating equipment for PTFE membrane filter media. After electrostatic hot pressing, the membrane is cooled by a fan to fix the shape and prevent deformation. The hydraulic rod inside the support frame is used for extension and retraction, so that the fixed plate hinged to the hydraulic rod can be adjusted in angle with the fan, which helps to cool more evenly. Before electrostatic hot pressing, the membrane is preheated by a fan and the heating frame below it to facilitate the subsequent hot pressing process. The motor on the outside of the receiving box rotates the lead screw, so that the moving frame threaded to the lead screw can move the mounting frame. The movement of the mounting frame brings the heating frame back into the receiving box.

[0004] This utility model also provides an electrostatic hot-press coating device for the above-mentioned PTFE membrane filter media, comprising: a base, a coating device body mounted on the upper surface of the base, a support frame fixedly connected to the upper surface of the base, a hydraulic rod hinged to the inner side of the support frame, a fixed plate hinged to the output end of the hydraulic rod, a fan fixedly connected to the inner wall of the fixed plate, a receiving box fixedly connected to the inner wall of the support frame, a motor fixedly connected to the outer surface of the receiving box, a lead screw fixedly connected to the output end of the motor, a movable frame threadedly connected to the outer surface of the lead screw, an installation frame fixedly connected to one end of the movable frame, and a heating frame installed on the inner wall of the installation frame.

The design of the anti-slip pad can effectively improve the stability of the equipment base.

[0012] Compared with existing technologies, this PTFE membrane filter media electrostatic hot pressing coating equipment uses a fan to cool the membrane after electrostatic hot pressing, which helps to shape the membrane and prevent deformation. The hydraulic rod inside the support frame is used for extension and retraction, allowing the fixed plate hinged to the hydraulic rod to adjust the angle of the fan, which helps to cool more evenly. Before electrostatic hot pressing, the membrane is preheated by the fan and the heating frame below it, which facilitates the subsequent hot pressing process. The motor on the outside of the receiving box rotates the lead screw, which allows the moving frame connected to the lead screw to move the mounting frame. The movement of the mounting frame brings the heating frame back into the receiving box. Attached Figure Description
