Description

Technical Field

[0001] The present application relates to the technical field of water filtration, and in particular to a white tape segment wrapping device for a reverse osmosis membrane element. Background Art

[0002] As people's requirements for drinking water quality increase, pure water systems are gradually entering the drinking water system of every household. At present, water purifiers on the market generally use reverse osmosis membrane elements, which can filter impurities such as organic matter, colloids, bacteria, viruses, etc. in raw water, especially inorganic salts, heavy metal ions and other impurities with extremely high filtration efficiency.

[0003] The reverse osmosis membrane element is formed by rolling a reverse osmosis membrane, a pure water guide net, and a raw water guide net around a water collecting pipe, and the outer periphery is fixed with waterproof tape to form a cylindrical membrane element. Small holes are set on the water collecting pipe to collect pure water and then discharge it from the water outlet. Among them, a leather cup is set at the water inlet end of the reverse osmosis membrane element, and the leather cup is fixed to the waterproof tape on the outer periphery of the membrane element by winding white tape to seal and fix it, so that raw water can only enter from the filter membrane interlayer at the water inlet end of the membrane element. After being filtered by the filter membrane, pure water is collected through the water collecting pipe and flows out of the water outlet of the water collecting pipe, preventing raw water from entering from the filter membrane interlayer at the water outlet to form backflow. Most of the existing white tape winding methods are manual winding, that is, people take the membrane element with assembled leather cups and manually wrap white tape around it. After the white tape is wound a specified number of times, it is manually cut.

[0004] Doing so will result in low manual operation efficiency and greater demand for manpower and working hours, resulting in higher manufacturing costs and increased processing costs. In addition, since the leather cup is set on the periphery of the membrane element, the interface between the leather cup and the membrane element is uneven. When wrapping the white tape, it is necessary to manually pull the white tape so that the white tape is more closely wrapped around the interface between the two. Affected by the fatigue factor of long-term manual operation, the sealing and firmness of the tape winding are also easily affected, making it difficult to ensure the processing quality.

[0053] In this embodiment, when installing the white tape, the white tape is installed from the outside to the inside (i.e. Figure 3 The self-locking feed tray is installed on the feed tray body 11 (from right to left in the direction shown). For the convenience of description, the locking direction of the self-locking feed tray and the installation direction of the white tape are set in the same direction, and the adjustment direction of the self-locking feed tray and the installation direction of the white tape are set in the opposite direction.

The slider 12 is slidably connected to the outer groove of the feed tray body 11 through the positioning pin 13, and the pressure plate 14 is axially connected to the outer side of the feed tray body 11 through the positioning push platform 15. Under the action of the positioning push platform 15, the pressure plate 14 moves axially along the feed tray body 11. The pressure plate 14 drives the slider 12 to slide obliquely in the outer groove of the feed tray body 11 through the translational movement to accommodate the placement of rolled white tapes with different inner diameters and realize the self-locking fixing of the white tape.

[0055] Specifically, Figure 4 This is a schematic diagram of an enlarged state of the feed tray 11 in this application, as shown Figure 4 As shown, the feed tray body 11 includes a plurality of slider receiving grooves 111, avoidance grooves 112, baffle blocks 113 and positioning pin mounting holes 114. The slider receiving grooves 111 are peripheral grooves located at the circumference of the feed tray body 11 for accommodating the slider 12. The avoidance grooves 112 are avoidance structures located at the circumference of the feed tray body 11. The plurality of slider receiving grooves 111 and the plurality of avoidance grooves 112 are arranged at intervals along the circumference of the feed tray body 11, so that the slider A blocking block 113 is formed between the accommodating groove 111 and the avoiding groove 112, and the blocking block 113 is provided with a positioning pin mounting hole 114 radially penetrating the slider accommodating groove 111, and the positioning pin mounting holes 114 on both sides of each slider accommodating groove 111 cooperate with each other to install the positioning pin 13, so that the positioning pin 13 penetrates and is connected to the positioning pin mounting holes 114 on both sides of the slider accommodating groove 111, and the slider 12 is slidably connected in the slider accommodating groove 111.

[0056] Further, the slider receiving groove 111 is an open groove with three groove walls, the outer side and the top of the slider receiving groove 111 are open, and the length of the slider receiving groove 111 along the axial direction of the feed tray 11 is a1, and the slider 12 is a slider received in the slider receiving groove 111, and the length of the slider 12 is a2, a1>a2, which is used to realize the displacement distance of the slider 12 along the slider receiving groove 111;

The first slot 121 cooperates with the positioning pin 13 to slide the slider 12 into the slider accommodating groove 111, so that when the slider 12 is pushed to move along the axial direction of the feed tray 11, the positioning pin 13 is obliquely displaced in the first slot 121, thereby realizing the oblique sliding displacement of the slider 12 along the slider accommodating groove 111.

[0058] Specifically, along the locking direction of the self-locking feed tray, the first slot hole 121 is located on the side wall of the slider 12, and is obliquely arranged along the diagonal direction from the inner top surface of the slider 12 to the outer bottom surface, so that during the locking process of the self-locking feed tray, the slider 12 moves inward in the slider accommodating groove 111 along the axial direction of the feed tray body 11, and the slider 12 slides and moves toward its top surface along the radial direction of the feed tray body 11 until the top surface of the slider 12 is higher than the top surface of the slider accommodating groove 111 at the circumference, and is fixed with white tape.

[0059] It should be noted that the inner top surface of the slider 12 refers to two surfaces, namely, the inner end surface of the slider 12 facing away from the pressure plate 14, and the top surface of the slider 12 facing away from the bottom of the slider accommodating groove 111; correspondingly, the outer bottom surface of the slider 12 refers to two surfaces, namely, the outer end surface of the slider 12 facing away from the first mounting plate 10, and the bottom surface of the slider 12 facing the bottom of the slider accommodating groove 111.
