[0029] The dynamic pressure regulating assembly includes a first support slide rod 701, two bearing seats 702, two fixed bushings 703, two pressure sensors 704, two hydraulic cylinders 705, a driven pulley 706, a drive motor 707, a drive pulley 708, a belt 709, a fixing frame 710, a tension wheel 711, and a tension spring 712. The first support slide rod 701 is fixedly installed inside the first fixing seat 4 and the second fixing seat 5. The bearing seats 702 are slidably connected to the outer wall of the first support slide rod 701. The fixed bushings 703 are rotatably connected to the middle of the bearing seats 702. The pressure sensors 704 are fixedly installed at one end of the bearing seats 702. The hydraulic cylinders 705 are fixedly installed at one end of the first fixing seat 4 and the second fixing seat 5. The driven pulley 706 is fixedly installed at one end of the fixed bushing 703 located inside the second fixing seat 5. The drive motor 707 is fixedly installed on one side of the second fixing seat 5. The drive pulley 706 is also fixedly installed at the same location. 708 is fixedly installed at one end of the output shaft of the drive motor 707. Belt 709 is movably installed between the drive pulley 708 and the driven pulley 706. One end of the fixed frame 710 is rotatably connected to one side of the second fixed seat 5.

Two fixed shaft sleeves 703 are respectively sleeved on both ends of the rotating shaft of the membrane roller 6. The output ends of two hydraulic cylinders 705 are respectively fixedly installed at one end of the pressure sensor 704 located inside the first fixed seat 4 and the second fixed seat 5. The inner side of tension wheel 711 abuts against the middle surface of belt 709. One end of tension spring 712 is fixedly installed inside one end of the fixed frame 710.

[0030] The drive motor 707, driven pulley 708, belt 709, fixed frame 710, tension wheel 711, and tension spring 712 are configured as follows: In use, the drive motor 707 drives the fixed bushing 703 to rotate through the cooperation of the driven pulley 708, belt 709, and driven pulley 706. The rotation of the fixed bushing 703 drives the film roller 6 to rotate. The tension spring 712 can tighten the fixed frame 710, so that the tension wheel 711 can be tightly attached to the belt 709, so that the belt 709 can always be kept taut. The drive motor 707 is a speed-regulating motor.

[0031] In this embodiment, a pressure sensor 704 is used to detect the pressure between the hydraulic cylinder 705 and the bearing seat 702. By pushing or pulling the pressure sensor 704 connected to it through the two hydraulic cylinders 705, the two bearing seats 702 can slide on the outer walls of the two sets of first support slide rods 701 respectively, adjusting the distance between the film roller 6 and the bottom roller 3. According to the speed of the drive motor 707 and the pressure applied to the pressure sensor 704, the two hydraulic cylinders 705 can push or pull the pressure sensor 704 connected to it during operation, causing the two bearing seats 702 to slide on the outer walls of the two sets of first support slide rods 701 respectively. This allows the film roller 6 to automatically adjust the pressure of the film roller 6 on the material between the film roller 6 and the bottom roller 3 according to the speed of the drive motor 707 during processing.

[0032] In one embodiment, the fixed base moving assembly includes a slide groove 801, two second support slide rods 802, an adjusting screw 803, a bracket 804, and a turntable 805. The slide groove 801 is formed on one side of the second base 2. The two second support slide rods 802 are slidably connected to the inner side of the slide groove 801. The adjusting screw 803 is rotatably connected to the inner side of the second base 2. The bracket 804 is fixedly installed between the second support slide rods 802 and the second fixed base 5. The turntable 805 is fixedly installed at one end of the adjusting screw 803. The two second support slide rods 802... The diameter matches the width and length of the slide groove 801. The middle of the two second support slide rods 802 is provided with screw holes that match the adjusting screw 803, and both second support slide rods 802 are threadedly connected to the adjusting screw 803. The first fixed seat 4 is fixedly installed on one side of the first base 1, and the second fixed seat 5 is slidably connected to one side of the second base 2. The two ends of the membrane roller 6 shaft are provided with slots 9. The inner sides of the two fixed bushings 703 are fixedly connected with inserts 10. The shape of the inserts 10 matches the shape of the slots 9. A direct drainage channel is also provided inside the filter cartridge housing.

[0033] This embodiment features a sliding second fixed seat 5. During use, rotating the turntable 805 engages the adjusting screw 803 with the second support slide rod 802, causing the two second support slide rods 802 to move the bracket 804, which in turn moves the second fixed seat 5 outwards. Adjusting the distance between the second fixed seat 5 and the first fixed seat 4, and consequently the distance between the two fixed bushings 703, allows the shaft of the film roller 6 to be pulled out of the bushing 702 for quick disassembly. Then, the replacement film roller 6 is removed, and the slots 9 at both ends of the shaft of the required film roller 6 are aligned with the two fixed bushings 703. Rotating the turntable 805 again engages the adjusting screw 803 with the second support slide rod 802, causing the two second support slide rods 802 to move the bracket 804, resetting the second fixed seat 5. Simultaneously, the insert block 10 is inserted into the slot 9, completing the fixing of the required film roller 6.

[0034] Instructions: Before use, rotate the turntable 805 to engage the adjusting screw 803 with the second support slide bar 802, causing the two second support slide bars 802 to move the bracket 804, which in turn moves the second fixed seat 5 outward. Adjust the distance between the second fixed seat 5 and the first fixed seat 4, thereby adjusting the distance between the two fixed bushings 703. This allows the shaft of the film roller 6 to be pulled out of the bushing 702, quickly removing the film roller 6. Then, take out the replacement film roller 6 and align the slots 9 at both ends of the shaft of the required film roller 6 with the two fixed bushings 703. Rotate the turntable 805 to engage the adjusting screw 803 with the second support slide bar 802, causing the two second support slide bars 802 to move outward. 802 drives the bracket 804 to move, resetting the second fixed seat 5. At the same time, the insert block 10 will be inserted into the slot 9 to complete the fixing of the membrane roller 6. Then, in use, the drive motor 707 drives the fixed bushing 703 to rotate through the cooperation of the active pulley 708, belt 709 and driven pulley 706. The rotation of the fixed bushing 703 can drive the membrane roller 6 to rotate. During operation, the two hydraulic cylinders 705 push or pull the pressure sensor 704 connected to them, causing the two bearings 702 to slide on the outer wall of the two sets of first support slide rods 701 respectively. This allows the membrane roller 6 to automatically adjust the pressure of the membrane roller 6 on the material between the membrane roller 6 and the bottom roller 3 according to the speed of the drive motor 707.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
