Technical Field

[0001] This utility model relates to the field of RO membrane production technology, and in particular to an automatic roll-up machine for RO membrane production. Background Technology

[0002] RO membrane production refers to the process of using high molecular materials such as polyamide as the core, and going through multiple precision processes such as casting solution preparation, coating or spinning to form a membrane, cross-linking cleaning and drying, to make a semi-permeable membrane with reverse osmosis function that can selectively allow water molecules to pass through while retaining salts and impurities.

[0003] RO membrane production involves multiple continuous processes. Traditional roll changing relies on manual disassembly of the old roll and installation of the new roll, which is cumbersome and time-consuming. This can lead to forced interruptions in the production process, reducing overall production efficiency and potentially causing membrane tension fluctuations, which can affect the stability of subsequent processes. To address these issues, we propose an automatic roll changing machine for RO membrane production. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 In this utility model, an automatic roll-changing film machine for RO membrane production includes a machine base 1. A frame 2 is fixedly installed on the upper surface of the machine base 1. A roll-changing assembly 3 is provided on the inner wall and the back of the frame 2. A locking assembly 4 is provided on the outer surface of the roll-changing assembly 3 and the outer surface of the frame 2. A material guiding assembly 5 is fixedly connected to the upper surface of the machine base 1. A tensioning clamping conveyor assembly 6 is fixedly installed on the upper surface of the machine base 1. A control board 7 is fixedly installed on the front of the machine base 1. A work light 8 is fixedly installed on the upper surface of the frame 2. A support rod 9 is fixedly installed on the bottom surface of the machine base 1. The outer surface of each locking rod 404 is coated.

[0021] The frame 2 serves as both support and protection for the roll changing assembly 3, ensuring operational safety and precision. The roll changing assembly 3 enables automatic film roll switching, reducing manual labor time and improving production continuity. The locking assembly 4 precisely locks the roll changing assembly 3 after roll changing, preventing the unwinding roller 309 from shaking and ensuring stable unwinding. The material guiding assembly 5 organizes the film material conveying path to avoid deviation and wrinkles. The tension clamping conveying assembly 6 provides constant tension, improving the RO membrane forming quality. The control board 7 serves as the operation center, enabling parameter setting and real-time control. The support rod 9 supports the machine platform 1 and levels it, ensuring equipment stability. The surface coating of the locking rod 404 enhances wear resistance and rust prevention, extends its service life, and reduces locking friction.

[0022] The roll changing assembly 3 includes a motor 301. The outer surface of the motor 301 is fixedly installed on the inner wall of the frame 2. The output end of the motor 301 is fixedly connected to a rotating shaft 302. The outer surface of the rotating shaft 302 is fixedly connected to a drive gear 303. The outer surface of the frame 2 is fixedly embedded with a first bearing 304. The inner ring of the first bearing 304 is fixedly connected to a rotating rod 305. The outer surface of the rotating rod 305 is fixedly connected to a driven gear 306. The outer surface of the drive gear 303 meshes with the outer surface of the driven gear 306. One end of the rotating rod 305 is fixedly connected to a rotating plate 307. The front side of the rotating plate 307 is fixedly embedded with two second bearings 308. The inner ring of each second bearing 308 is fixedly connected to an unwinding roller 309.

[0023] The motor 301 of the roll changing assembly 3 provides power, which drives the drive gear 303 to rotate via the rotating shaft 302. The drive gear 303 meshes with the driven gear 306, and drives the rotating plate 307 to rotate via the rotating rod 305. The two second bearings 308 on the rotating plate 307 are respectively installed with unwinding rollers 309. The rotation of the rotating plate 307 realizes the switching of the positions of the two unwinding rollers 309. The gear transmission ensures that the rotating plate 307 rotates accurately and smoothly.

[0024] The locking assembly 4 includes two openings 401, which are opened together on the outer surface of the frame 2. Two electric push rods 402 are fixedly installed on the back of the frame 2. The output ends of the two electric push rods 402 are fixedly connected to a movable frame 403. Two locking rods 404 are fixedly connected to the front of the movable frame 403. Two locking holes 405 are opened on the outer surface of the rotating plate 307. The two locking rods 404 are respectively located inside the two locking holes 405.

[0025] In the locking assembly 4, the electric push rod 402 drives the moving frame 403, which in turn drives the two locking rods 404 to extend and retract synchronously. After the locking rods 404 are inserted into the locking ports 405 of the rotating plate 307, the double locking structure can firmly fix the position of the rotating plate 307, preventing the rotating plate 307 from rotating or shaking during unwinding, thus ensuring the continuity of RO membrane production and product quality.

[0026] The working principle of this utility model is as follows: When the automatic roll-changing film machine is working, the machine base 1 serves as the basic support, the frame 2 provides the mounting frame, and the roll-changing assembly 3 is responsible for changing the roll of film. In the initial state, the locking rod 404 in the locking assembly 4 is inserted into the locking slot 405 of the turn plate 307 to lock it. One of the unwinding rollers 309 is in the working position to unwind the RO film. The RO film is guided by the material guide assembly 5 to the tension clamping and conveying assembly 6, which maintains the tension and conveys it. When a roll change is required, the control board 7 controls the electric push rod 402 to retract, which drives the moving frame 403 and the locking rod 404 to move backward, so that the locking rod 404 disengages from the locking slot 405. The roller is retracted through opening 401, releasing the lock on the rotating plate 307. Then, the motor 301 starts, driving the rotating shaft 302 and the drive gear 303 to rotate. The drive gear 303 meshes with the driven gear 306, causing the rotating rod 305 to rotate in the first bearing 304, which in turn drives the rotating plate 307 to rotate, turning another spare unwinding roller 309 to the working position. Then, the electric push rod 402 extends, pushing the locking rod 404 through the opening 401 and inserting it into the corresponding locking port 405 to relock the rotating plate 307, completing the roll change. The support rod 9 supports the machine base 1, and the coating on the outside of the locking rod 404 enhances its performance.
