Description

Technical Field

[0001] This utility model relates to the technical field of film winding machines, specifically, to an RO membrane filter winding device. Background Technology

[0002] During the production of RO membrane filter cartridges, the filter cartridges need to be clamped and fixed before being rotated to wind the RO membrane. However, existing filter cartridges are usually placed manually or automatically. Both methods involve directly placing the filter cartridge in the winding area and then clamping it at both ends. During clamping, because the filter cartridge is not pre-positioned, it can only be roughly placed in the designated position before clamping, which makes the filter cartridge prone to positional deviation, resulting in misalignment during RO membrane winding.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an RO membrane filter cartridge winding device, including a movable frame, a first connecting plate installed at one end of the movable frame, and a second connecting plate installed at the other end. The first connecting plate and the second connecting plate are both mounted on a base plate through a first slide rail slider. A rotatable limiting shaft is installed on the first connecting plate, and a top shaft that can reciprocate in the direction of the limiting shaft is installed on the second connecting plate.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] Combination Figures 1 to 4 An RO membrane filter cartridge winding device is shown, comprising a movable frame 1, with a first connecting plate 4 mounted at one end and a second connecting plate 8 mounted at the other end. Both the first connecting plate 4 and the second connecting plate 8 are mounted on a base plate 3 via a first slide rail slider 2. A rotatable limiting shaft 7 is mounted on the first connecting plate 4, and a top shaft 12 that can reciprocate towards the limiting shaft 7 is mounted on the second connecting plate 8. A pressure roller assembly is disposed between the limiting shaft 7 and the top shaft 12, and the pressure roller assembly is telescopically mounted on the movable frame 1. In this embodiment, the limiting shaft 7 can be first inserted into one end of the filter tube 20 to initially limit the position of the filter tube 20. Then, it is moved by the top shaft 12 and inserted into the filter tube 20, so that the filter tube 20 is accurately clamped between the limiting shaft 7 and the top shaft 12, preventing positional deviation that could cause the RO membrane to be wound off-center. Moreover, the limiting shaft 7 can drive the filter tube 20 to rotate for winding, and the pressure roller assembly can extend towards the filter tube 20 to press the RO membrane 21 tightly during edge winding, thereby improving product quality.

[0017] In this embodiment, a fixed vertical plate 14 is provided on one side of the substrate 3, and a first cylinder 15 is installed on the movable frame 1. The cylinder body of the first cylinder 15 is fixed on the movable frame 1, and the cylinder shaft of the first cylinder 15 is connected to the fixed vertical plate 14. By pushing the first cylinder 15, the movable frame 1 moves along the first slide rail slider 2, so as to drive the clamped filter tube 20 to move to the designated position. Here, the first slide rail slider 2 is set along the input direction of the RO membrane 21.

[0018] In this embodiment, a reduction motor 6 is mounted on the first connecting plate 4. A limiting shaft 7 is connected to the motor shaft of the reduction motor 6. The limiting shaft 7 includes a connecting section 70, one end of which is connected to the motor shaft, and the other end is provided with a first insertion section 71. The diameter of the first insertion section 71 is smaller than the diameter of the connecting section 70. The top shaft 12 includes a rotating shaft 120. A second insertion section 121 is provided at the end of the rotating shaft 120 facing the first insertion section 71. The support of the second insertion section 121 is smaller than the diameter of the rotating shaft 120. Before clamping the filter element tube 20, the filter element is first... One end of the tube 20 is fitted onto the first insertion section 71, so that one end face of the filter tube 20 presses against the end of the connecting section 70, thus initially limiting the filter tube 20. Then, the top shaft 12 moves so that the second insertion section 121 is inserted into the other end of the filter tube 20 until the filter tube 20 presses against the rotating shaft 120, thereby completing the clamping of the filter tube 20. This allows the filter tube 20 to be rotated and wound around the RO membrane 21 by the reduction motor 6, preventing the filter tube 20 from deviating from its position. Before winding, the RO membrane 21 is first adhered to the outer wall of the filter tube 20.

[0019] In this embodiment, a slide plate 10 is mounted on the upper end of the second connecting plate 8 via a second slide rail slider 9. A bearing seat 11 is mounted on the upper end of the slide plate 10, and a bearing 5 is installed inside the bearing seat 11. A top shaft 12 is installed inside the bearing 5.

Here, the second slide rail slider 9 is perpendicular to the top projection of the first slide rail slider 2. The second cylinder 13 drives the slide plate 10 to move, thereby driving the top shaft 12 on the bearing seat 11 to move, so as to clamp or release the filter tube 20.

[0020] The pressure roller assembly of this embodiment includes a pressure frame 16, a guide rod 18 passing through the movable frame 1, one side of the pressure frame 16 connected to the guide rod 18, and a pressure roller 19 mounted on the other side of the pressure frame 16.

The pressure frame 16 is moved by the third cylinder 17, so that the pressure roller 19 can press on the RO membrane 21 during the process of the filter tube 20 winding the RO membrane 21, making the RO membrane 21 tighter and improving the quality of the product. The guide rod 18 can make the pressure frame 16 more stable during the movement and prevent shaking.
