[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the first motor drives the connecting shaft to rotate, thereby driving the rotating frame to rotate, and the rotating frame drives multiple fixed shafts to rotate synchronously, and the fixed shaft drives the winding drum to rotate; when the fixed shaft rotates, the docking grooves at both ends of the fixed shaft can be accurately aligned and stuck on the docking blocks at the ends of the two output shafts to achieve a stable connection, and then the two second motors drive the corresponding output shafts to rotate respectively, and the winding drum is driven to rotate through the docking blocks on the output shafts, thereby realizing automatic winding of the microfiltration membrane, which not only simplifies the process of replacing the winding drum, but also greatly improves the winding efficiency of the microfiltration membrane.

[0017] 2. In the present invention, during the rotation of the rotating frame, multiple rollers rotate accordingly, and the rollers roll smoothly along the inner wall of the mounting sleeve. The rollers maintain close contact with the inner wall of the mounting sleeve, providing additional support and stability for the rotating frame, which not only ensures the stability of the rotating frame during high-speed rotation, but also further improves the stability and reliability of the entire winding system.

[0018] 3. In the present invention, in order to ensure the stability of the rotating frame when the fixed axis rotates, the cylinder is operated to push the positioning rod to be inserted into the positioning hole on the rotating frame, providing additional fixation for the rotating frame, which not only enhances the structural stability of the rotating frame, but also ensures the smooth winding of the microfiltration membrane during the winding process, thereby further improving the overall work efficiency and product quality.

[0019] 4. In the present invention, in order to quickly replace the winding drum, the positioning rod is driven by the cylinder to quickly move out of the positioning hole, thereby releasing the fixation of the rotating frame. Subsequently, the first motor is started to drive the rotating frame to rotate, so that the two ends of the fixed shaft are moved out of the docking block, which not only realizes the rapid disassembly of the old winding drum, but also prepares for the installation of the new winding drum. The entire replacement process only requires a short shutdown, which greatly improves the replacement efficiency of the winding drum and ensures the continuity and efficiency of the production line.

[0020] 5. In the present invention, the two limit arms on the fixed shaft are pressed at the same time, so that the limit arms rotate around the second rotating shaft. As the limit arms rotate, the first hinge seat is pushed to slide along the outer wall of the limit rod through the connecting arm, and the extrusion ring is pushed to slide on the limit rod through the first hinge seat, thereby squeezing the second spring. In this process, the abutment effect originally produced by the limit block on the limit arm on the outer wall of the winding drum is released, so the winding drum is no longer limited. Under the elastic force of the first spring, the extrusion disk begins to push the winding drum to slide outward along the fixed shaft. The entire disassembly process is fast and smooth, which significantly improves the disassembly efficiency of the winding drum and provides convenience for subsequent replacement and maintenance work.

[0021] 6. In the present invention, when installing a new winding drum, the new winding drum is sleeved on the fixed shaft, and the end of the winding drum will squeeze the outer wall of the limit arm, causing the limit arm to flip inward to the inside of the installation cavity. As the limit arm moves, under the elastic force of the second spring, the limit arm will push the limit block to flip to the outside of the installation cavity. At the same time, the insertion of the winding drum will squeeze the end of the extrusion disk, thereby pushing the connecting rod to slide smoothly along the inner wall of the rotating frame. In this process, the first spring will be gradually stretched. As the extrusion disk continues to push, the end of the winding drum will tightly abut against the limit block, thereby realizing the rapid installation of the winding drum. The entire installation process does not require complicated tools or cumbersome steps, greatly improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Embodiment 4: Figures 5 to 8 As shown, this embodiment is based on the previous embodiment, and the difference from the previous embodiment is that:

[0043] The mounting assembly 3 comprises a plurality of fixed shafts 302, the circumferential outer walls of the fixed shafts 302 are slidably connected with the winding drum 301, the inner wall protrusions of the winding drum 301 are plugged into the outer wall grooves of the fixed shaft 302, and the winding drum 301 can be limitedly mounted, docking grooves 303 are respectively provided at both ends of the fixed shaft 302, the ends of the winding drum 301 are respectively magnetically connected to the extrusion disk 208, the ends of the fixed shaft 302 are respectively connected to the inner walls of the mounting hole 207 for damping rotation, the docking grooves 303 are respectively snap-fitted with the docking blocks 104, and the ends of the fixed shaft 302 pass through the extrusion disk 208 and are slidably connected to the inner wall.

[0044] Two installation cavities 304 are provided on the circumferential outer wall of the fixed shaft 302, and the inner walls of the installation cavities 304 are fixedly connected to the limiting rods 305, and the circumferential outer walls of the limiting rods 305 are fixedly connected to the limiting rings 309, and the circumferential outer walls of the limiting rods 305 are slidably connected to the extrusion rings 310, and the circumferential outer walls of the limiting rods 305 are sleeved with second springs 311, one end of the second springs 311 is fixedly connected to the inner wall of the fixed shaft 302, and the other end of the second springs 311 is fixedly connected to the extrusion ring 310.

[0045] The inner wall of the installation cavity 304 is fixedly connected with the second rotating shaft 312, the circumferential outer wall of the second rotating shaft 312 is rotatably connected with the limiting arm 313, the outer side of the limiting arm 313 is fixedly connected with the limiting block 314, the inner side of the limiting arm 313 is fixedly connected with the second hinge seat 308, the inner wall of the second hinge seat 308 is rotatably connected with the connecting arm 307, the end of the connecting arm 307 is fixedly connected with the first hinge seat 306, the end of the limiting rod 305 passes through the first hinge seat 306 and is slidably connected thereto, and the first hinge seat 306 is located between the limiting ring 309 and the extrusion ring 310.

[0046] The positioning rod 111 is driven by the cylinder 110 to move out from the positioning hole 203, and the rotating frame 202 is driven to rotate by the first motor 107, so that the two ends of the fixed shaft 302 can be respectively moved out from the docking block 104, so that the fixed shaft 302 can be quickly disassembled and the new winding drum 301 can be installed at the same time, so that the winding drum 301 can be quickly replaced during a short shutdown, thereby improving the winding efficiency of the microfiltration membrane.

[0047] Working principle: The first motor 107 drives the connecting shaft 105 to rotate, thereby driving the rotating frame 202 to rotate, and the rotating frame 202 drives multiple fixed shafts 302 to rotate synchronously, and the fixed shaft 302 drives the winding drum 301 to rotate;

[0048] When the fixed shaft 302 rotates, the docking grooves 303 at both ends thereof can be accurately aligned and stuck on the docking blocks 104 at the ends of the two output shafts 103 to achieve a stable connection. Subsequently, the two second motors 109 respectively drive the corresponding output shafts 103 to rotate, and the docking blocks 104 on the output shafts 103 drive the winding drum 301 to rotate, thereby achieving automatic winding of the microfiltration membrane.

[0049] During the rotation of the rotating frame 202, the plurality of rollers 206 rotate accordingly, and the rollers 206 roll smoothly along the inner wall of the mounting sleeve 201, and the rollers 206 maintain close contact with the inner wall of the mounting sleeve 201, thereby providing additional support and stability for the rotating frame 202;

[0050] In order to ensure the stability of the rotating frame 202 when the fixed shaft 302 rotates, the cylinder 110 runs to push the positioning rod 111 to be inserted into the positioning hole 203 on the rotating frame 202, providing additional fixation for the rotating frame 202, which not only enhances the structural stability of the rotating frame 202, but also ensures the smooth winding of the microfiltration membrane during the winding process, thereby further improving the overall work efficiency and product quality.

[0051] In order to quickly replace the winding drum 301, the cylinder 110 drives the positioning rod 111 to quickly move out of the positioning hole 203, thereby releasing the fixation of the rotating frame 202. Subsequently, the first motor 107 is started to drive the rotating frame 202 to rotate, so that the two ends of the fixed shaft 302 are moved out of the docking block 104, thereby realizing the rapid disassembly of the old winding drum 301 and preparing for the installation of the new winding drum 301.

[0052] The two limit arms 313 on the fixed shaft 302 are pressed at the same time, so that the limit arms 313 rotate around the second rotating shaft 312. As the limit arms 313 rotate, the first hinge seat 306 is pushed to slide along the outer wall of the limit rod 305 through the connecting arm 307, and the extrusion ring 310 is pushed to slide on the limit rod 305 through the first hinge seat 306, thereby squeezing the second spring 311.

[0053] During this process, the abutment effect of the limit block 314 on the limit arm 313 on the outer wall of the winding drum 301 is released, and the winding drum 301 is no longer limited. Under the elastic force of the first spring 210, the squeezing plate 208 starts to push the winding drum 301 to slide outward along the fixed shaft 302, and the whole disassembly process is fast and smooth.

[0054] When installing a new winding drum 301, the new winding drum 301 is put on the fixed shaft 302, and the end of the winding drum 301 will squeeze the outer wall of the limit arm 313, causing the limit arm 313 to flip inward to the inside of the installation cavity 304. As the limit arm 313 moves, under the elastic force of the second spring 311, the limit arm 313 will push the limit block 314 to flip to the outside of the installation cavity 304.

[0055] At the same time, the insertion of the winding drum 301 will squeeze the end of the extrusion disk 208, thereby pushing the connecting rod 209 to slide smoothly along the inner wall of the rotating frame 202. During this process, the first spring 210 will be gradually stretched. As the extrusion disk 208 continues to push, the end of the winding drum 301 will tightly abut against the limit block 314, thereby realizing the rapid installation of the winding drum 301.
