Description

Technical Field

[0001] This utility model relates to the field of composite membrane filter material manufacturing technology, and in particular to a high-temperature resistant PTFE composite membrane filter material manufacturing equipment. Background Technology

[0002] PTFE composite membrane filter media is the core component of filter media. It has a unique microporous structure with uniform and small pore size, usually in the submicron range. PTFE composite membranes are usually made using a laminating machine. The laminating machine can precisely control the lamination process of the PTFE membrane with other materials such as the base fabric, ensuring the bonding accuracy and uniformity between the two.

[0003] Specifically, in the production of PTFE composite membranes, a laminating machine is used. This machine applies pressure to the PTFE membrane and the base fabric using rollers and other devices. This pressure ensures tight contact between the PTFE membrane and the base fabric, eliminating air gaps and allowing the adhesive to better fill the tiny gaps between them. This increases the contact area between the adhesive and both materials, thereby improving adhesion. However, during the PTFE membrane traction and conveying process, the traction device moves the membrane, causing it to loosen. When the PTFE membrane is loose, wrinkles and other problems will appear after the membrane is prepared. Therefore, to solve this problem, we propose a high-temperature resistant PTFE composite membrane filter material manufacturing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistant PTFE composite membrane filter material manufacturing equipment to avoid the problem of PTFE composite membrane loosening during the manufacturing process, which leads to wrinkles in the carbon fiber cloth weaving. In addition, the second positioning roller limits the position of the PTFE composite membrane to ensure that the PTFE composite membrane is positioned during the pressing process.

[0005] To achieve the above objectives, a high-temperature resistant PTFE composite membrane filter material manufacturing equipment is provided, comprising a housing. A first feeding roller is movably fitted inside the housing, and a second feeding roller is movably fitted above the first feeding roller inside the housing. Two first guide rollers are movably fitted inside the housing in front of the first and second feeding rollers. A discharge port is provided inside the housing, and a first traction roller is movably fitted behind the discharge port. A support frame is fixedly installed on the front side of the housing. A first telescopic motor is fixedly installed on the upper part of the support frame, and a second telescopic motor is fixedly installed on the lower part of the support frame. A movable... The movable sleeve has a telescopic rod movably fitted inside each of the movable sleeves. A fixed plate is fixedly installed above the telescopic rod. Two second guide rollers are movably fitted inside the fixed plate. A support rod is fixedly installed at the front end of the fixed plate. A limit rod is fixedly installed at the front end of the support rod. A positioning rod is fixedly installed at the front end of the limit rod. A first positioning roller is movably fitted inside the positioning rod. A spring is fixedly connected to the outside of the limit rod. A roller is movably fitted on the top of the spring. A machine body is fixedly installed on the front side of the support frame. Two second traction rollers are movably fitted on the rear side of the machine body. Two second positioning rollers are movably fitted on the front side of the machine body. A bracket is fixedly installed on the front side of the machine body.

[0006] According to the high-temperature resistant PTFE composite membrane filter material manufacturing equipment, the movable sleeve is installed at both the upper and lower ends of the support frame, and the first telescopic motor and the second telescopic motor are both fixedly connected to the fixed plate.

[0007] According to the high-temperature resistant PTFE composite membrane filter material manufacturing equipment, a set of springs and rollers are installed on the upper part of the limiting rod and two are installed on the lower part.

[0008] According to the high-temperature resistant PTFE composite membrane filter material manufacturing equipment, a PTFE membrane is sleeved on the outside of the first feeding roller, and a base fabric is sleeved on the outside of the second feeding roller. The PTFE membrane and base fabric sleeved on the outside of the first feeding roller and the second feeding roller are simultaneously sleeved on the outside of the first guide roller and the first traction roller in sequence. The PTFE membrane and base fabric sleeved on the outside of the first traction roller pass through the second guide roller and are successively sleeved on the outside of three sets of rollers. The PTFE membrane and base fabric sleeved on the outside of the rollers pass through the first positioning roller and are sleeved between the two second traction rollers. Two pressing rollers are movably installed inside the machine body. The PTFE membrane and base fabric between the second traction rollers are simultaneously sleeved between the two pressing rollers.

[0009] Beneficial effects:

[0010] 1. A spring is fixedly installed on the outside of the limiting rod, and a roller is movably mounted above the spring. The spring drives the roller to provide elastic power to the PTFE membrane and the base fabric. At the same time, the PTFE membrane and the base fabric can maintain a state of tension balance when moving, so as to avoid the problem of wrinkles caused by the loosening of the PTFE membrane and the base fabric during the production process.

[0011] 2. The second traction roller, which is mounted on the rear side of the machine body, pulls the PTFE membrane and the base fabric during the pressing process. At the same time, the pressing roller drives the PTFE membrane and the base fabric to press together, and the second positioning roller limits the position of the PTFE membrane and the base fabric to ensure that the PTFE membrane and the base fabric are positioned during the pressing process.
