[0023] 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.

[0024] like Figure 1 This is a schematic structural diagram of the utility model, a nanofiltration membrane sheet cutting device, comprising:

[0025] Rack 1, which is used for equipment installation;

[0026] The cutting mechanism 2 includes a cutting assembly 21, a reset assembly 22 and a mounting seat 23. The mounting seat 23 is arranged on the frame 1. A sliding cavity 231 extending along the length direction of the frame 1 is provided in the mounting seat 23. A connecting cavity 232 communicating with the sliding cavity 231 is provided on the top surface of the mounting seat 23. A portion of the cutting assembly 21 is located in the sliding cavity 231. The cutting assembly 21 and the sliding cavity 231 are slidably connected. The cutting assembly 21 is used to cut the nanofiltration membrane sheet. The reset assembly 22 is located in the sliding cavity 231. Through the design of the reset assembly 22 and the sliding cavity 231 on the mounting seat 23, the user can push the cutting assembly 21 on one side to complete the cutting of the nanofiltration membrane sheet and return it to the initial position under the action of the reset assembly 22 after the cutting is completed. It is convenient and quick to use and can improve the cutting efficiency.

[0027] In the initial state, the cutting assembly 21 is located on the left side of the mounting seat 23, and the reset assembly 22 is located on the right side of the mounting seat 23. The reset assembly 22 includes a reset spring 221. One end of the reset spring 221 is fixedly connected to the right side wall of the sliding cavity 231 of the mounting seat 23. The reset spring 221 is used to absorb the potential energy of the cutting assembly 21 and react to the cutting assembly 21.

[0028] The cutting assembly 21 is located on the left side of the mounting seat 23 and is in an initial state.

[0029] The mounting seat 23 is arranged obliquely, and the height of the right end of the mounting seat 23 is higher than the height of the left end of the mounting seat 23 .

[0030] like Figure 4 、 Figure 5 As shown, the cutting mechanism 2 includes an adjusting component 24, which is used to adjust the height of the right side of the mounting seat 23. The adjusting component 24 is arranged on the frame 1, and the adjusting end of the adjusting component 24 is transmission-connected to the right end of the mounting seat 23.

[0031] like Figure 4 、 Figure 5 As shown, the adjustment assembly 24 includes an adjustment seat 241 and an adjustment screw 242 . The adjustment seat 241 is fixedly connected to the frame 1 , and the adjustment screw 242 is threadedly connected to the adjustment seat 241 . The top end of the adjustment screw 242 abuts against the bottom surface of the right end of the mounting seat 23 .

[0032] like Figure 2 、 Figure 3 As shown, the cutting mechanism 2 includes a cutter 211 and a slider 212. The slider 212 matches the sliding cavity 231. The slider 212 is slidably arranged in the sliding cavity 231. The cutter 211 and the slider 212 are fixedly connected. The outer ring of the cutting knife of the cutter 211 extends into the connecting cavity 232. The width of the connecting cavity 232 is smaller than the width of the sliding cavity 231, which can prevent the slider 212 from slipping.

[0033] like Figure 2 、 Figure 3 As shown, the cutting mechanism 2 includes a buffer assembly 25, which is used to absorb the potential energy of the cutting assembly 21 when it is reset, so that the cutting assembly 21 stays in the initial position. The buffer assembly 25 includes a buffer spring 251, and the buffer spring 251 is fixedly connected to the left side wall of the sliding cavity 231 of the mounting seat 23.

[0034] like Figure 2 、 Figure 3 As shown, the reset assembly 22 includes a reset block 222 , which is slidably arranged in the sliding cavity 231 . The reset block 222 is fixedly connected to the left end of the reset spring 221 , and the reset block 222 is used to contact the slider 212 .

[0035] Working principle: When in use, the nanofiltration membrane sheet is laid on the frame 1 and over the mounting seat 23. At this time, the nanofiltration membrane sheet is located above the mounting seat 23, and the cutting component 21 is located on the left side of the mounting seat 23. The user pushes the cutter 211 of the cutting component 21 to move it to the right side of the mounting seat 23. During the movement, the cutting knife of the cutter 211 completes the cutting of the nanofiltration membrane sheet. When the cutting component 21 moves to the right side of the mounting seat 23, it contacts the reset spring 221 or the reset block 222, compressing the reset spring 221, so that the reset spring 221 accumulates elastic potential energy. When the reset spring 221 recovers, it pushes the cutting component 21 to move to the left side of the mounting seat 23 until it is reset. At this time, the potential energy of the cutting component 21 is basically consumed. If there is any residual potential energy, it will also be absorbed by the buffer spring 251 to avoid its direct impact.

[0036] 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.
