Abstract

[0002] Nanofiltration membrane cutting devices play a vital role in the water treatment and chemical industries. Their precise cutting capabilities directly impact the performance and service life of membrane modules. However, conventional nanofiltration membrane cutting devices have several operational shortcomings. These devices often require fine-tuning after being fixed to ensure accurate cutting direction (the cutting device's two-end fixed structure requires accurate cutting direction calibration). This process often involves tedious loosening and re-clamping steps, which is not only time-consuming but also easily affects cutting accuracy.
[0003] In early designs, the fixing of cutting devices often relied on rigid structures such as bolts or clamps. These structures provided stability when fixing the cutting devices, but were not flexible enough when fine-tuning was required. The operator had to first loosen the fixing device, adjust it to the desired position, and then re-fix it. This process not only increased the complexity of the operation, but could also lead to errors in the cutting process. Utility Model Content

DETAILED DESCRIPTION
[0019] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.
[0020] like Figure 1 : This is a structural schematic diagram of the utility model, a nanofiltration membrane adjustable cutting device, including a frame 1, a cutting mechanism 2 and a fixing mechanism 3, the cutting mechanism 2 is used for nanofiltration membrane, the cutting mechanism 2 includes a mounting seat 21 and a cutter 22, the cutter 22 and the mounting seat 21 are slidably connected, the fixing mechanism 3 includes an elastic band 31 and two fixing components 32, the two fixing components 32 are respectively arranged at both ends of the mounting seat 21, the fixing component 32 includes a fixing seat 321, a locking rod 322, a connecting seat 323 and a connecting component 324, the locking rod 322 is a threaded rod, and a connecting portion 3211 and a pressing portion 3212 are protruded on the fixing seat 321, the pressing portion 3212 is used to contact with the frame 1, the locking rod 322 and the connecting portion 3211 are threadedly connected, and the pressing portion 3212 and the locking rod The 322 clamps the frame 1, the connecting seat 323 is fixedly connected to the mounting seat 21, the connecting assembly 324 is fixedly connected to the connecting seat 323 on its side, a guide wheel 3231 is arranged on the connecting seat 323, and a pressure plate 325 is arranged on the fixing seat 321. A fixing cavity 3251 for the elastic band 31 to pass through is formed between the pressure plate 325 and the fixing seat 321. The width of the fixing cavity 3251 is greater than the width of the elastic band 31. The ends of the elastic band 31 pass through the guide wheel 3231 and the fixing cavity 3251 in turn and are connected to the connecting assembly 324. The cutting mechanism is tightly fixed by the elastic band 31, so that the cutting mechanism 2 can press the frame 1. At the same time, the elasticity of the elastic band 31 is used to pull it to achieve fine adjustment, avoiding frequent loosening and locking steps, and significantly improving the adjustment efficiency.
[0021] like Figure 3 、 Figure 4 As shown, the fixing seat 321 has two pressing parts 3212 , which are spaced apart, and a gap is formed between the two pressing parts 3212 for the connecting seat 323 to move.
[0022] like Figure 2 、 Figure 4 As shown, the connecting assembly 324 includes a connecting rod 3241 and several stabilizing assemblies. The connecting rod 3241 is fixedly connected to the connecting seat 323. The stabilizing assembly is used to stabilize the connecting rod 3241. The stabilizing assembly includes two stabilizing wheels 3242 arranged at intervals. The stabilizing wheels 3242 are rotatably connected to the fixing seat 321. There is a gap between the two stabilizing wheels 3242 through which the connecting rod 3241 passes. The connecting rod 3241 and the stabilizing wheels 3242 are in rolling contact. The end of the elastic band 31 is fixedly connected to the connecting rod 3241 on its side. The connecting assembly 324 can increase the guiding and limiting effects to prevent the cutting mechanism 2 from shaking at will. There is a gap between the connecting rod 3241 and the stabilizing wheel 3242 for the connecting rod 3241 to move, and the width of the gap is less than or equal to the width of the fixing cavity 3251.
[0023] like Figure 2 、 Figure 4 As shown, the fixing assembly 32 includes a pulling spring 326, one end of the pulling spring 326 is fixedly connected to the fixing seat 321, and the other end is fixedly connected to the elastic band 31. The pulling spring 326 is used to increase the clamping force so that the cutting mechanism 2 can press the frame 1 tightly to ensure that it will not be displaced during the cutting process.
[0024] like Figure 2 、 Figure 4 As shown, the connecting assembly 324 includes a guide wheel 327 , which is rotatably connected to the connecting rod 3241 , and the elastic band 31 passes around the guide wheel 327 .
[0025] like Figure 2 、 Figure 4 As shown, the stabilizing components are distributed at intervals along the vertical direction, and the fixing seat 321 has multiple stabilizing components, and there are at least two stabilizing components, which can enable the connecting rod 3241 to have multiple supporting points to ensure its direction.
[0026] When the cam 32 is in the unlock state, the locking lever 322 is rotated until the top of the locking lever 322 is against the frame 1, thereby achieving the overall fixation of the fixing seat 321 under the clamping of the locking lever 322 and the pressing portion 3212. The mounting seat 21 of the cutting mechanism 2 is fixed with a connecting seat 323. The connecting rod 3241 on the connecting seat 323 is inserted between the two stabilizing wheels 3242. The end of the elastic band 31 passes through the guide wheel 3231 and the fixing cavity 3251 in sequence and is connected to the connecting assembly 324. Furthermore, the end of the elastic band 31 is fixedly connected to the pulling spring 326. The elastic band 31 and the pulling spring 326 reset the cutting mechanism 2 to squeeze the frame 1 and provide corresponding force.
[0027] When the cutting line of the cutting mechanism 2 needs to be adjusted, the connecting seat 323 on one side is lifted, and then the connecting seat 323 is moved left and right to move its position. However, due to the force limitation of the elastic band 31 and the pulling spring 326, the movement of the connecting seat 323 requires a certain force (the vibration of the cutting mechanism 2 is sufficient to move it, and the design of the elastic band 31 and the pulling spring 326 has a certain shock-absorbing effect), thereby achieving fine adjustment of the connecting seat 323 without the need for locking and loosening, which is highly efficient.
[0028] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
