Description

Technical Field

[0001] The present invention relates to a winding device for a membrane material of a reverse osmosis membrane element and a working method thereof. Background Art

[0002] The reverse osmosis membrane element is a highly efficient water separation technology and is widely used in household and industrial applications. In a household environment, this technology is mainly used to purify tap water, effectively removing impurities such as iron, copper, cadmium, chromium, lead, etc., so as to provide high-quality drinking water and cooking water. In addition, it can also be used for the purification of cement floors and swimming pool water. In the industrial field, reverse osmosis membrane elements are widely used in multiple industries such as water treatment, beverage production, electronic manufacturing, chemical industry, food processing, etc., and can convert wastewater, seawater, groundwater, etc. into high-quality pure water. There are significant differences between household osmosis membranes and industrial osmosis membranes in terms of application scenarios, filtration performance, and structural design. Household membranes are characterized by miniaturization, lightweight, easy installation, and easy maintenance. Their filtration accuracy is usually 0.0001 microns, which can remove most impurities and bacteria, but the treatment effect on pathogenic viruses and chemical pollutants is limited. In contrast, industrial reverse osmosis membranes are applied to large-scale water treatment systems, with a higher filtration accuracy of 0.00001 microns, which can effectively remove bacteria, viruses, solvents, heavy metals, radioactive elements, etc. in water, providing high-quality pure water for various industrial production scenarios.

[0003] Currently, in the production process of industrial nano reverse osmosis membrane elements, each link including the cutting, stacking, and winding of key materials such as membrane sheets is completed separately by different mechanical equipment, and then it depends on manual handling to the next equipment for further processing. This approach not only slows down the production efficiency and increases the production cost due to manual intervention, but also exposes the problem of insufficient automation and intelligence level. More seriously, given the large volume of industrial reverse osmosis membrane elements, manual handling is extremely inconvenient, and it is easy to cause scratches or damage to the elements during the handling process, which directly affects the filtration performance of the finished elements and leads to an increase in the rejection rate.

[0004] Chinese Patent with the publication number CN115217522A discloses an automated pre-processing equipment for industrial reverse osmosis membrane elements, which can complete the full-automatic production of industrial osmosis membranes, including a folding and cutting mechanism, a central tube feeding and film pasting mechanism, and an automatic film winding mechanism. However, in the prior art, during the film material transfer process in the winding process, the film material is easily damaged. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies existing in the prior art, and to provide a reasonably designed winding device for a membrane material of a reverse osmosis membrane element and a working method thereof, in which the membrane material is not easily damaged during the transfer process in the winding process.

[0006] The technical solution adopted by the present invention to solve the above problems is: a winding device for a membrane material of a reverse osmosis membrane element, including a handling manipulator, a gluing platform, and a gluing manipulator; characterized in that: it further includes a pallet mechanism and a film winding mechanism; the pallet mechanism includes a movable pallet, a fixed pallet, and a pallet moving mechanism; the fixed pallet is fixedly installed on the machine frame; the movable pallet is movably installed on the machine frame, above the fixed pallet; the pallet moving mechanism is connected to the movable pallet; the film winding mechanism includes a film winding machine, a bracket, and a film rubbing device; the film winding machine and the bracket are both fixedly installed on the machine frame; the film rubbing device includes a film rubbing roller, a film rubbing roller rotating mechanism, and a film rubbing roller moving mechanism; the film rubbing roller moving mechanism is installed on the machine frame, the film rubbing roller and the film rubbing roller driving mechanism are installed on the film rubbing roller moving mechanism, and the film rubbing roller rotating mechanism is connected to the film rubbing roller.

(2) For the semi-finished reverse osmosis membrane element produced, the inlet separation net is in an unfolded state on the semi-finished product; the handling manipulator puts the semi-finished reverse osmosis membrane element into the film winding machine, and at the same time puts the unfolded inlet separation net on the bracket. (3) The handling manipulator lays the glued first membrane material flat on the movable pallet, and then continues to move forward with the first membrane material. After the front part of the first membrane material crosses the movable pallet, it is laid on the fixed pallet, and the rear part of the first membrane material remains on the movable pallet; the handling manipulator releases the first membrane material, and the pallet moving mechanism drives the movable pallet to move backward, and the rear part of the first membrane material gradually is also laid on the fixed pallet until the entire first membrane material is laid on the fixed pallet. (4) The film rubbing roller moving mechanism drives the film rubbing roller and the film rubbing roller driving mechanism to move. The film rubbing roller presses on the unfolded water inlet partition net. The film rubbing roller rotating mechanism drives the film rubbing roller to rotate, and the film rubbing roller lifts the water inlet partition net upward, so that a space with a certain gap is formed between the water inlet partition net and the scaffolding.

[0035] (2) For the semi-finished reverse osmosis membrane element produced, its inlet separation net is in an unfolded state on the semi-finished product. The handling manipulator 6 puts the semi-finished reverse osmosis membrane element on the shelf into the film winder 41, and at the same time puts the unfolded inlet separation net on the bracket 42; the film rubbing pressing plate rotating mechanism 47 drives the film rubbing pressing plate 46 to rotate, and presses the film rubbing pressing plate 46 on the inlet separation net, the function of which is to ensure that the inlet separation net does not move randomly during film rubbing, facilitating the smooth progress of the film picking action.
