Description

Technical Field

[0001] The present application relates to the technical field of warp knitting machines, and particularly relates to a warp knitting mechanism for preparing RO reverse osmosis membrane base fabrics. Background Art

[0002] For the sinkers in the existing warp knitting mechanisms, the main body part is generally an integrally formed mechanism. To adjust its sinking height, it is often adjusted through the installation structure of the warp knitting machine connected to it, which is rather inconvenient. Moreover, the traditional warp knitting of RO reverse osmosis membrane base fabrics mostly uses a knitting density of 28 needles or 32 needles. When further increasing its knitting density, the load on the parts in the knitting mechanism is greater. Therefore, the number of needles per inch is correspondingly increased on the sinkers, groove needles, guide flower needles, and needle cores, resulting in an increased force of the yarn on the parts. The parts are more likely to be worn out after long-term use and need to be replaced more frequently, greatly increasing the maintenance cost of the equipment. Summary of the Utility Model

[0003] In order to overcome the problems existing in the prior art, the present application provides a warp knitting mechanism for preparing RO reverse osmosis membrane base fabrics.

[0004] The warp knitting mechanism for preparing RO reverse osmosis membrane base fabrics provided by the present application adopts the following technical solutions:

[0005] A warp knitting mechanism for preparing RO reverse osmosis membrane base fabrics includes sinkers, groove needles, guide flower needles, needle cores, and a frame for respectively installing the above-mentioned parts. The sinker includes a fixing mechanism. A plurality of sinker hammers are spaced at the bottom of the fixing mechanism. A closing rod is provided at one end of the sinker hammer away from the fixing mechanism. The groove needle and the guide flower needle are respectively fixedly installed on the frame by bolts. The needle core is clamped in the pillow core groove and fixed by a locking mechanism.

[0006] Preferably, the fixing mechanism adopts a split structure, including a fixing main body and a gasket installed on the side of the fixing main body close to the frame. The fixing main body is integrally formed with the sinker hammer, and the gasket is installed between the fixing main body and the frame.

[0007] By adopting the above technical solutions, the knitting mechanism of the warp knitting machine weaves the RO reverse osmosis membrane base fabric through the cooperation of the sinkers, groove needles, guide flower needles, and needle cores respectively installed on the frame, and different numbers of needles can be selected according to the required density. The integral formation of the fixing main body and the sinker hammer ensures the strength and stability of the overall structure of the sinker. A gasket is provided at the connection between the sinker and the frame, enabling the single replacement of the fixing main body or the gasket after long-term use, effectively reducing the maintenance cost.

[0008] Preferably, a protrusion for fitting and limiting at the corner of the frame is provided on one side of the fixing mechanism close to the frame, and the gasket is clamped on the contact surfaces of the fixing mechanism and the protrusion with the frame, and the gasket protrudes from the surface of the fixing mechanism.

[0009] Preferably, the protrusions are arranged at the bottoms of both sides of the main body of the fixing mechanism. The protrusions are in the shape of right-angled triangular prisms, the hypotenuse of the protrusion is integrally formed with the main body of the fixing mechanism, and the short right-angled side of the protrusion is connected to the frame.

[0010] Preferably, the surface of the protrusion on the edge of the fixing mechanism is on the same horizontal plane as the fixing mechanism, and the opposite surface of the protrusion on the fixing mechanism is an inclined plane extending towards the surface of the fixing mechanism.

[0011] Preferably, the main body of the gasket is of a rectangular structure. On both sides of one end of the gasket close to the protrusion and the end far from the protrusion, there are clamping blocks for clamping with the fixing main body, and one side of the gasket close to the protrusion is also adapted to the groove on the surface of the protrusion.

[0012] By adopting the above technical solutions, the protrusions on the fixing mechanism are in the shape of right-angled triangular prisms. The protrusions are integrally formed with the fixing mechanism through their inclined planes, and the protrusions are also arranged in two groups at the bottom of the main body of the fixing mechanism, which can reduce the contact area between the protrusions and the frame, ensure the stability of their connection, and through the design of the inclined planes between the two groups of protrusions, further strengthen the stability of the protrusions and the whole fixing mechanism. And the short right-angled sides of the protrusions are abutted and fixed with the frame to stably install the sinker on the frame. The gasket is prominently installed on the surface of the fixing mechanism, the gasket is embedded on the surfaces of the fixing mechanism and the protrusions, and both sides of the gasket are clamped with the surface of the fixing mechanism through the clamping blocks to prevent the gasket from slipping and affecting the weaving quality of the embryo cloth.

[0013] Preferably, the needle core includes an integrally formed mounting block and a needle body. The needle body is connected to the top surface of the mounting block. The locking mechanism abuts against the top surface of the mounting block through a locking block and fixedly installs the needle core in the needle core groove. The locking block is of an L-shaped structure, and the other side of the locking block is attached to the outside of the needle core groove and fixed by bolts.

[0014] By adopting the above technical solutions, the needle core is embedded in the needle core groove and fixed by the locking mechanism. The locking block of the L-shaped structure in the locking mechanism locks the needle core in the needle core groove, which is also convenient for the maintenance and replacement of the needle core.

[0015] Preferably, the sinker, the groove needle, the guide flower needle and the needle core all adopt 34 needles.

[0016] By adopting the above technical solutions, compared with the traditional knitting mechanisms of 28 needles and 32 needles, the 34 needles have a better filtering effect on the woven RO reverse osmosis membrane embryo cloth.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] By updating the knitting mechanisms of 28 needles and 32 needles for traditional woven RO reverse osmosis membrane blanks in the present application to a 34-needle design, and setting gaskets at the connection between the sinker and the frame, it is possible to replace the fixing body or the gasket individually after long-term use, effectively reducing the maintenance cost.

The integral forming of the fixing main body 111 and the sinker hammer 12 ensures the strength and stability of the overall structure of the sinker 1. Among them, a gasket 112 is provided at the connection between the sinker 1 and the frame 5, which can enable the individual replacement of the fixing main body 111 or the gasket 112 after long-term use, effectively reducing the maintenance cost.
