Description

Technical Field

[0001] This invention relates to a winding mechanism for a fully automated RO membrane winding production line, and also to a winding process. Background Technology

[0002] As people's requirements for the quality of domestic drinking water continue to increase, pure water systems are gradually being adopted by every household. Currently, water purifiers on the market generally use RO membrane filters or reverse osmosis filters. Reverse osmosis filters can filter out pollutants such as organic matter, colloids, bacteria, and viruses from raw water, especially inorganic salts and heavy metals, exhibiting extremely high filtration efficiency. Therefore, the reverse osmosis filter element is the core component of a water purifier, and the filtration effect of the water purifier directly affects the filtration effect of the reverse osmosis filter element.

[0003] A typical RO membrane filter element includes a central tube and reverse osmosis membrane units wound around the central tube. The reverse osmosis membrane units are formed by stacking several layers of mesh, filter membrane and guide cloth. Finally, a blue adhesive membrane is provided on the outermost layer to wrap these mesh, filter membrane and guide cloth into a filter element.

[0004] The last step in our automated production line is to wrap the rolled RO membrane filter element with a layer of adhesive film. However, with existing technology, when rolling the last unit, the portion of the adhesive film that is not enough to wrap a complete filter unit needs to be used up to facilitate the replacement of a new adhesive film roll. The amount of adhesive film roll used is not large. When replacing the adhesive film roll, we will stop the automated production line to replace the adhesive film roll.

[0005] When changing the film roll, our traditional method is to provide a reversing function to the material rollers. When the material roll is almost at the end, the reversing function pulls the film roll out. Alternatively, we can manually tear the film roll off the wrapping rollers and then replace it with a brand new film roll. However, these operations prolong the manual operation time, resulting in low work efficiency and being time-consuming and labor-intensive. Summary of the Invention

[0006] To overcome the time-consuming and labor-intensive process of handling the film roll tail during the current membrane element rolling and forming process, this invention provides a membrane element rolling and forming and unloading mechanism and its processing technology.

[0007] The technical solution of the present invention to solve its technical problem is: a membrane element rolling and unloading mechanism, including a frame, wherein the frame is provided with a central tube feeding device, an element outer ring adhesive film winding device, an adhesive film feeding and cutting device, and an unloading and sorting device;

[0008] The central tube feeding device includes a hopper, with a single tube lifting assembly at the front of the hopper; it also includes a central tube clamping and transferring robot, which moves between the single lifting assembly, the component outer ring adhesive film winding device, and the discharge sorting device.

[0009] The outer ring adhesive film winding device of the component includes a movable table slidably mounted on a horizontal guide rail. A central tube clamping assembly is provided on the movable table. The central tube on the central tube clamping assembly can rotate with the movement. A longitudinal guide rail is also provided on the movable table. An auxiliary platform is provided on the longitudinal guide rail. An auxiliary roller with a power unit is provided on the auxiliary platform. After the auxiliary platform moves forward, the auxiliary roller abuts against the central tube on the central tube clamping assembly.

[0010] The adhesive film feeding and cutting device includes a lifting platform movably disposed below the central tube clamping assembly and a fixed adhesive film roller. The adhesive film roller is powered and has an adhesive film measuring head for detecting adhesive film thickness on one side. The lifting platform is provided with an adhesive film contact platform and an adhesive film pressure roller assembly. A lifting platform drive unit is provided at the lower end of the lifting platform to drive it up and down. When the lifting platform moves up, the adhesive film contact platform abuts against the central tube on the central tube clamping assembly. A cutting guide rail is provided laterally at the front end of the lifting platform, and an adhesive film cutter is movably disposed on the cutting guide rail.

[0011] The material sorting device includes a finished product outlet and a defective product outlet.

Feeding plates are located below both sides of the discharge platform, and these plates can move up and down to lift the finished products on the discharge platform and allow them to roll into the finished product outlet. When the discharge platform moves to a position away from the finished product outlet, an intermediate support platform is located near it, with transition plates on both sides. The intermediate support platform is driven by an intermediate support platform lifting unit and can move up and down.

[0012] The mucosal cutter is preferably designed such that it is mounted on a mucosal cutter platform, which is driven by a mucosal cutter platform drive unit to move left and right.

[0013] The hopper structure is optimized such that the hopper of the central tube feeding device is lower in the front and higher in the back, the feeding tray is lower on the side near the finished product outlet, and the transition tray is lower on the side near the discharge platform.

[0017] The structure of the defective product discharge port is optimized, and the defective product discharge port is equipped with a defective product container.

[0018] To facilitate the discharge of the central tube on the hopper, the single-tube lifting assembly includes a lifting block that can accommodate a single central tube, and the lower end of the lifting block is equipped with a central tube lifting cylinder.

[0019] The present invention also includes a material sorting and processing technology, including the following steps: a) installing the adhesive film roll on the adhesive film roller, and laying the roll head flat along the adhesive film roller on the adhesive film contact platform with the adhesive side facing up;

[0020] b. When the adhesive film roll has sufficient adhesive film length, after the filter element is wrapped with the filter cloth in the outer ring adhesive film winding device, the filter element moves down and makes contact with the adhesive film on the adhesive film contact platform, and then wraps this ring of adhesive film. After the adhesive film is wrapped, the cutter cuts off the tail of the adhesive film to complete the outer ring wrapping, and the finished product falls into the middle tray of the discharge sorting device.

[0021] When the film measuring head detects that the film roll is too short, the central tube rotates and descends directly in the film winding device on the outer ring of the component, contacts the film and cleans the film roll. Then the central tube with the film falls into the middle tray of the discharge sorting device.

[0022] c. The discharge sorting device sorts the finished product and the central tube with adhesive film based on the data fed back by the adhesive film measuring head. The central tube with adhesive film enters the defective product discharge port under the action of the defective product pusher.

[0023] Step a involves placing a batch of center tubes in a hopper, which can accommodate center tubes of different lengths.

[0024] In use, the rotational power of the central tube is provided by the assist roller on the assist platform. The assist roller can drive the central tube to rotate when it is in close contact with the central tube.

[0025] The beneficial effects of this invention are as follows: 1. The hopper can be adapted to use center tubes of different sizes. Under the action of the center tube clamping and transfer robot, the center tube can be easily moved to the outer ring adhesive film winding device of the element to complete the winding, thus having wide application adaptability. 2.
