Specific implementation mode
[0021] The present utility model will be further described below with reference to the drawings and embodiments.
[0022] Please refer to Figures 1-4 , the present utility model provides an embodiment: an ultrafiltration membrane positioning and cutting device, including a vertical frame 1 and a support rod 2; further including a positioning component and a cutting component. A positioning component for ultrafiltration membrane cutting and positioning is provided at the left end of the vertical frame 1, and a cutting component is installed at the top of the vertical frame 1. Support rods 2 are provided at the four corners of the bottom end of the vertical frame 1. The positioning component includes a bracket 301, a chute 302 and a pressing plate 303. Brackets 301 are installed at the four corners of the top end of the vertical frame 1. A chute 302 is opened on the opposite side of the left-end bracket 301, and a pressing plate 303 is slidably connected between the left-end brackets 301.
[0023] Please refer to Figures 2-4 , in this embodiment, a sliding block 304 is slidably connected inside the chute 302, and the sliding block 304 is fixedly connected to one end of the pressing plate 303 close to the bracket 301. Vertical plates 305 are installed on the front and rear sides of the left end of the vertical frame 1, and support rods 306 are rotatably connected to the opposite sides of the vertical plates 305; a coupling shaft 307 is connected between the vertical plates 305 and the support rods 306. A limiting rod 308 is installed at the upper end of the opposite side of the vertical plate 305. An installation groove 309 is opened at the top end on the left side of the support rod 306. The left end of the support rod 306 is rotatably connected to an adjusting rod 310. A limiting ring 311 is connected to the adjusting rod 310 close to the installation groove 309 by means of a bearing. When the sliding block 304 slides in the chute 302, it drives the pressing plate 303 to move downward to squeeze the ultrafiltration membrane, preventing the ultrafiltration membrane from shifting during cutting and generating errors. At the same time, under the cooperation of the limiting roller 403 and the pressing plate 303, the ultrafiltration membrane is positioned, improving its working efficiency. After cutting, it slides onto the sliding roller 411 for collection and use.
[0024] Please refer to Figures 3-4, in this embodiment, the cutting assembly includes a sliding rod 401, a limiting tube 402, a limiting roller 403, a clamping plate 404, a connecting rod 405, a sliding tube 406, a fixing plate 407, a cutting knife 409, a support frame 410 and a sliding roller 411. The sliding rod 401 is movably connected inside the installation groove 309, and the limiting tube 402 is installed on one side of the sliding rod 401 facing each other; two groups of limiting rollers 403 are cross-installed between the vertical plates 305 near the side of the vertical frame 1, and two groups of clamping plates 404 are sleeved on the outer sides of the limiting rollers 403, and a connecting rod 405 is installed between the brackets 301; the sliding tube 406 is slidably connected to the outer side of the connecting rod 405, and the fixing plate 407 is installed between the sliding tubes 406, and a slider is slidably connected to the bottom end of the fixing plate 407, and a telescopic cylinder 408 is oppositely installed at the bottom end of the slider of the fixing plate 407; the telescopic end of the telescopic cylinder 408 is connected to the cutting knife 409, and a support frame 410 is installed at the right end of the vertical frame 1, and a sliding roller 411 is arranged between the support frames 410. Rotating the adjusting rod 310 drives the limiting ring 311 to be clamped inside the sliding rod 401 to limit and fix the sliding rod 401 to prevent the ultrafiltration membrane from falling off; the front end of the ultrafiltration membrane is cross-placed on the limiting rollers 403, and the relative sliding clamping plates 404 limit both ends of the ultrafiltration membrane to prevent the ultrafiltration membrane from shifting. The ultrafiltration membrane slowly moves under the cutting knife 409 to cut the ultrafiltration membrane.
[0025] When working, both ends of the ultrafiltration membrane are respectively inserted into the limiting tubes 402, and the sliding rod 401 is clamped inside the installation groove 309. After the clamping is completed, rotating the adjusting rod 310 drives the limiting ring 311 to be clamped inside the sliding rod 401 to limit and fix the sliding rod 401 to prevent the ultrafiltration membrane from falling off; the front end of the ultrafiltration membrane is cross-placed on the limiting rollers 403, and the relative sliding clamping plates 404 limit both ends of the ultrafiltration membrane to prevent the ultrafiltration membrane from shifting. The ultrafiltration membrane slowly moves under the cutting knife 409. When the sliding block 304 slides in the sliding groove 302, it drives the pressing plate 303 to move downward to press the ultrafiltration membrane to prevent the ultrafiltration membrane from shifting during cutting and generating errors. At the same time, under the cooperation of the limiting rollers 403 and the pressing plate 303, the ultrafiltration membrane is positioned to improve its working efficiency. After cutting, it slides onto the sliding roller 411 for collection and use.
[0026] Through the above steps, under the action of the pressing plate 303, the membrane material can be flattened during the cutting process, making it not easy to move or deform, preventing the membrane material from being uneven at the cut surface due to its own elastic bending, helping to reduce the cutting error caused by the offset of the ultrafiltration membrane during cutting, and at the same time ensuring that the membrane material remains neat and orderly after cutting, and helping to reduce mistakes and waste during the cutting process and improve production efficiency; to solve the problem that the positioning structure of the cutting device is relatively single, which easily leads to the offset of the ultrafiltration membrane, unable to accurately control the cutting size and quantity, and reducing the filtration performance of the ultrafiltration membrane.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those skilled in the art.
