Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membrane preparation, and more specifically to a multifunctional reverse osmosis membrane automatic film rolling device. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. It is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate these substances and water under the action of higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.

[0003] After searching, the existing patent (publication number: CN220299921U) discloses an automatic film rolling device for reverse osmosis membrane production, including a base frame, a fixed plate symmetrically fixedly connected to the top of the base frame by bolts, and a winding and disassembly mechanism is arranged between the two fixed plates, and the winding and disassembly mechanism includes a placement slot, a traction rod, a driven gear, a rotating motor, a driving gear, a plug rod, a cover plate, a movable rod, a tension spring, a pressure plate, a cross plate, a top rod, a top plate, a leveling roller and a support spring. The utility model has a scientific and reasonable structure, is safe and convenient to use, and is provided with a winding and disassembly mechanism. The cover plate is fixed to the top of the fixed plate by an insertion rod, and then the tension spring is contracted to drive the movable rod and the pressure plate to move, and the traction rod is limited inside the placement slot to prevent the traction rod from sliding. At the same time, the driven gear on the outside of the traction rod is closely meshed with the driving gear, which is convenient for transmitting power, so that the rotating motor can drive the traction rod and the winding drum to rotate.

[0004] Today's automatic reverse osmosis membrane rolling operations mostly involve manually rolling the guide cloth on a winding roller and then manually attaching the membrane to the guide cloth through gluing operations. After multiple layers are stacked, the membrane is rolled up. During this process, the membrane and the guide cloth are not closely fitted, and need to be squeezed after rolling up, which is very cumbersome and will seriously affect the quality of the reverse osmosis membrane. Therefore, in order to solve the above problems, a multifunctional reverse osmosis membrane automatic rolling equipment is necessary. Utility Model Content
