Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a nanofiltration membrane cutting device. Background Technology

[0002] In existing technologies, nanofiltration membrane cutting devices typically include a stabilizing plate, a cutting blade, and a gripping mechanism. After cutting, the gripping mechanism needs to hold the membrane edge for transfer. However, because the gripping area of ​​the gripper overlaps with the stabilizing plate, an additional uncut portion (i.e., the "residual end") needs to be left on the membrane to avoid interference between the blade and the gripper, resulting in material waste (approximately 5%-8% membrane scrap) and affecting cutting efficiency. Furthermore, the membrane material is prone to wrinkling due to bidirectional stretching during the cutting process, affecting the quality of the finished product. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problem in the prior art that the clamping area of ​​the gripper and the stabilizing plate overlap, and to avoid interference between the cutter and the gripper, an additional uncut part (i.e., "reserved end") needs to be reserved on the membrane body, which leads to material waste, a nanofiltration membrane cutting device is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a nanofiltration membrane cutting device, comprising:

[0005] The base is used for equipment mounting, and the rack is arranged on the base;

[0006] A cutting mechanism, used to cut nanofiltration membranes, is arranged on the frame;

[0007] A stabilizing mechanism is used to clamp the nanofiltration membrane during the cutting process. The stabilizing mechanism is arranged on the frame and includes a stabilizing plate, a pressure plate, and a stabilizing drive. The stabilizing plate is fixedly connected to the frame, the pressure plate is located above the stabilizing plate, and the output end of the stabilizing drive is drivenly connected to the pressure plate. The stabilizing drive is used to provide power for the pressure plate to move away from or towards the stabilizing plate. A space is formed between the pressure plate and the stabilizing plate for the nanofiltration membrane to pass through. The front end of the stabilizing plate has lower clearance grooves spaced apart along the cutting direction, and the front end of the pressure plate has upper clearance grooves that correspond one-to-one with the lower clearance grooves. The upper and lower clearance grooves are used for the gripping part of the gripping mechanism to extend into.

[0008] The device includes a gripping mechanism that grips the end of the nanofiltration membrane, pulls it, and moves the cut nanofiltration membrane sheet to the storage station. The gripping mechanism is arranged on the base. Through the cooperation of the upper clearance groove on the pressure plate and the lower clearance groove on the stabilizing plate, the gripper retracts into the upper and lower clearance grooves during cutting, eliminating the need to reserve membrane edges and improving material utilization by more than 5%. The stabilizing mechanism keeps the membrane tension stable, avoids cutting wrinkles, and increases the yield rate to 98%.

[0009] To address the issue of how to arrange the cutting mechanism, the cutting mechanism further includes a cutting drive and a cutting blade. The cutting drive is fixedly connected to the frame, and the output end of the cutting drive is connected to the cutting blade. The cutting drive provides power for the movement of the cutting blade, and the cutting blade rests against the front end of the stabilizing plate.

[0010] To address the issue of how to arrange the gripping mechanism, the gripping mechanism further includes a motion drive component, a mounting base, and several gripping components. The motion drive component is arranged on the base, and its output end is connected to the mounting base via a transmission connection. The gripping components are arranged on the mounting base, and each gripping component corresponds to an upper clearance groove.

[0011] The device further includes a motion drive assembly comprising a slider, a slide rail that matches the slider, and a motion drive component. The slide rail and the base are fixedly connected, the slider and the slide rail are slidably connected, the output end of the motion drive component is drively connected to the slider, the motion drive component is used to provide power for the movement of the slider, and the slider and the mounting base are fixedly connected.

[0012] To address the safety issue of excessive slider movement potentially causing accidents, a further improvement is made by installing limit blocks on the slide rail. These limit blocks are used to control the slider's stroke.

[0013] It further includes guide rollers rotatably mounted on the frame for guiding the movement of the nanofiltration membrane.

[0014] The beneficial effects of this utility model are as follows: The nanofiltration membrane cutting device provided by this utility model, through the cooperation of the upper relief groove on the pressure plate and the lower relief groove on the stabilizing plate, allows the gripper to retract into the upper and lower relief grooves during cutting, eliminating the need to reserve the membrane edge and increasing the material utilization rate by more than 5%; the stabilizing mechanism keeps the membrane tension stable, avoids cutting wrinkles, and increases the yield rate to 98%.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figure 1 This is a schematic diagram of the structure of this utility model, a nanofiltration membrane cutting device, comprising:

[0024] The base 1 is used for equipment installation. A frame 11 is arranged on the base 1. A guide roller 111 for guiding the movement of the nanofiltration membrane is rotatably mounted on the frame 11. The guide roller is used to guide or control the movement of the nanofiltration membrane in a specific direction, while reducing friction and wear.

[0025] like Figure 1 , 2 As shown, the cutting mechanism 2 is used to cut the nanofiltration membrane. The cutting mechanism 2 is arranged on the frame 11. The cutting mechanism 2 includes a cutting drive 21 and a cutting blade 22. The cutting drive 21 is fixedly connected to the frame 11. The output end of the cutting drive 21 is connected to the cutting blade 22. The cutting drive 21 is used to provide power for the movement of the cutting blade 22. The cutting blade 22 is attached to the front end of the stabilizing plate 31.

[0026] like Figure 1 , 2 As shown, the stabilizing mechanism 3 is used to clamp the nanofiltration membrane during the cutting process. The stabilizing mechanism 3 is arranged on the frame 11 and includes a stabilizing plate 31, a pressure plate 32, and a stabilizing drive component 33. The stabilizing plate 31 is fixedly connected to the frame 11, and the pressure plate 32 is located above the stabilizing plate 31. The output end of the stabilizing drive component 33 is drively connected to the pressure plate 32. The stabilizing drive component 33 provides power to move the pressure plate 32 away from or towards the stabilizing plate 31. The stabilizing drive component 33 can be a cylinder, an electric actuator, or a lead screw mechanism, etc. A space is formed between the pressure plate 32 and the stabilizing plate 31 for the nanofiltration membrane to pass through. The front end of the plate 31 has lower clearance grooves 311 spaced apart along the cutting direction. The front end of the pressure plate 32 has upper clearance grooves 321 that correspond one-to-one with the lower clearance grooves 311. The upper clearance grooves 321 and lower clearance grooves 311 are used for the gripping part of the gripping mechanism 4 to extend into. Through the cooperation of the upper clearance grooves 321 on the pressure plate 32 and the lower clearance grooves 311 on the stabilizing plate 31, the gripping part retracts into the upper clearance grooves 321 and lower clearance grooves 311 during cutting, eliminating the need to reserve the edge of the film body and improving the material utilization rate by more than 5%. The stabilizing mechanism keeps the film tension stable, avoids cutting wrinkles, and increases the yield rate to 98%.

[0027] like Figure 1 , 2 As shown, the gripping mechanism 4 is used to grip the end of the nanofiltration membrane, pull the nanofiltration membrane, and move the cut nanofiltration membrane sheet to the storage station. The gripping mechanism 4 is arranged on the base 1.

[0028] The gripping mechanism 4 includes a moving drive assembly 41, a mounting base 42, and several gripping components 43. The moving drive assembly 41 is arranged on the base 1, and the output end of the moving drive assembly 41 is connected to the mounting base 42 for transmission. The gripping components 43 are arranged on the mounting base 42, and each gripping component 43 corresponds to an upper clearance groove 321. The gripping component 43 can be a cylinder gripper or a cleaver, etc. The gripping component 43 is used to grip nanofiltration membranes.

[0029] The moving drive assembly 41 includes a slider 411, a slide rail 412 that matches the slider 411, and a moving drive component 413. The moving drive component 413 can be a cylinder, an electric actuator, or a lead screw mechanism, etc. The slide rail 412 is fixedly connected to the base 1, the slider 411 is slidably connected to the slide rail 412, the output end of the moving drive component 413 is connected to the slider 411 for transmission, and the moving drive component 413 is used to provide power for the movement of the slider 411. The slider 411 is fixedly connected to the mounting base 42.

[0030] Limiting blocks 44 are installed on the slide rail 412. The limiting blocks 44 are used to control the stroke of the slider 411. The limiting blocks 44 restrict the movement range of the slider 412 to prevent it from exceeding the designed stroke, ensuring that the slider stops at a safe position at both ends of the guide rail, avoiding equipment collision or derailment due to misoperation or program error, preventing the slider from hitting the end of the guide rail or adjacent parts, and reducing the risk of mechanical damage.

[0031] Working principle:

[0032] In use, the nanofiltration membrane body passes between the pressure plate 32 and the stabilizing plate 31, with the front end of the nanofiltration membrane body protruding from the front end of the stabilizing plate 31. The gripping member 43 grips the front end of the nanofiltration membrane and moves backward until the portion of the nanofiltration membrane protruding from the front end of the stabilizing plate 31 is the required cutting width. At this time, the stabilizing drive member 33 causes the pressure plate 32 to move downward and clamp the nanofiltration membrane with the cooperation of the stabilizing plate 31. Then, the cutting drive member 21 is activated, causing the cutting plate 22 to move and cut the nanofiltration membrane. After the cutting is completed, the moving drive component 41 drives the gripper 43 to move away from the stabilizing mechanism 3 until the cut nanofiltration membrane moves to the storage position. The gripper releases its grip on the cut nanofiltration membrane sheet, and then the gripper continues to move backward a distance so that the cut nanofiltration membrane sheet can be completely separated from the gripper. This avoids the situation where the distance between the height of the gripper 43 and the topmost nanofiltration membrane sheet is too short when the nanofiltration membranes are piled up, resulting in insufficient space for falling.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
