Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane processing technology, and in particular to a longitudinal cutting device for reverse osmosis membrane processing. Background Technology

[0002] A reverse osmosis membrane is a permeable or semi-permeable membrane that allows water molecules to pass through while retaining solutes (such as inorganic salts, heavy metal ions, and organic matter) on one side of the membrane under pressure higher than the osmotic pressure of the solution. This achieves the separation and purification of the solution. Reverse osmosis membranes are typically made of polymers such as polyamide, polyurethane, and polyether. The raw materials are placed in a screw extruder, melted and extruded at high temperatures to form a continuous film. The resulting film is then cured and dried. Some specific reverse osmosis membranes also require modification treatment.

[0003] The prepared membrane material must be cut into appropriate sizes before it can be assembled into a membrane module. Since the supporting membrane material is a continuous state with a large width, it needs to be cut longitudinally to change the width of the membrane material so that it is cut into membrane sheets of appropriate size.

[0004] The existing publicly available technical solution, CN220864169U, discloses a longitudinal cutting device for reverse osmosis membrane processing, including a crossbeam. A cutting mechanism is installed at the bottom of the crossbeam. The cutting mechanism includes a connecting plate, a first electric push rod, a motor, a transmission belt, a reciprocating lead screw, a sleeve, a limiting block, a scraper, and a cutter. Through the cutting mechanism, the user can perform longitudinal cutting on the reverse osmosis membrane during processing.

[0005] The above technical solution uses a cutting mechanism to cut the membrane material. During the cutting process, a set of cutters is used to cut the membrane material. However, in actual use, the membrane sheet needs to be cut not only in length but also in width. This results in the membrane sheet needing to be put back into the cutting device for secondary cutting after being cut, which leads to low work efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a longitudinal cutting device for reverse osmosis membrane processing, which can cut the membrane material in two directions by means of a cutting blade and a longitudinal cutting blade working together, thereby improving cutting efficiency and solving the problems mentioned in the background art.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4A longitudinal cutting device for reverse osmosis membrane processing includes a cutting device base plate 1, a plurality of partition plates 8 are fixedly disposed on the top of the cutting device base plate 1, a membrane pulling assembly 2 is slidably installed on one side of the partition plate 8, a fixed bracket 6 fixed to the top of the cutting device base plate 1 is installed on the other side of the partition plate 8, a cutting assembly 3 for cutting membrane material is installed on the fixed bracket 6, a membrane material support plate 7 welded inside the fixed bracket 6 is disposed below the cutting assembly 3, and a plurality of longitudinal cutting blades 5 are installed on the top of the membrane material support plate 7;

[0028] The cutting assembly 3 includes a cutting blade 307. A movable slider 308 is screwed onto the top of the cutting blade 307. An adjusting screw 309 is connected to the inside of the movable slider 308 via a threaded sleeve. The power output end of a servo motor 301 is fixedly installed at the end of the adjusting screw 309. The cutting assembly 3 also includes a lifting cylinder 302 fixed to the top of the fixed bracket 6. A lower pressure plate 303 is fixedly connected to the telescopic end of the lifting cylinder 302. The cutting blade 307 is slidably mounted on the bottom of the lower pressure plate 303 via the movable slider 308. An elastic member 304 is provided on one side of the cutting blade 307 and fixed to the bottom of the lower pressure plate 303. A rubber column 306 passes through the inside of the elastic member 304. A rubber pressure plate 305 parallel to the membrane material support plate 7 is fixedly provided at the end of the rubber column 306.

[0029] By adopting the above technical solution, when the membrane material passes above the membrane material support plate 7, the lifting cylinder 302 is activated, which pushes the lower pressure plate 303 downward. One end of the lower pressure plate 303 is fixedly equipped with a servo motor 301. The downward movement of the lower pressure plate 303 can press the membrane material. The lower pressure plate 303 is located to the right of the longitudinal cutter 5. When the lower pressure plate 303 descends, it can drive the membrane material to move downward and contact the longitudinal cutter 5. The other end of the membrane material is lower than the longitudinal cutter 5, so that the membrane material is longitudinally cut by the longitudinal cutter 5, which works in conjunction with the membrane stretching assembly. As the film stretching assembly 2 moves, it can longitudinally cut the film material. Then, the servo motor 301 is started, and the servo motor 301 drives the adjusting screw 309 to rotate, which in turn drives the sliding slider 308 on the adjusting screw 309 to slide inside the lower pressure plate 303, thereby driving the cutting blade 307 to move. When the cutting blade 307 moves, it can cut the film material, realizing the cutting of the film material in two directions. By setting the cutting blade 307 and the longitudinal cutting blade 5 to cooperate with each other, the film material is cut in two directions, improving the cutting efficiency.

[0030] Specifically, such as Figure 4As shown, a cleaning assembly 4 is installed on the other side of the cutting blade 307. The cleaning assembly 4 includes a vertical plate 401 fixed to the bottom of the lower pressure plate 303, and an adjusting screw 402 is threaded inside the vertical plate 401. The end of the adjusting screw 402 is connected to a cleaning scraper 403 through a bearing. A telescopic rod 404 is also connected between the cleaning scraper 403 and the vertical plate 401.

[0031] The film stretching assembly 2 includes a gantry frame 201 that is slidably installed on the front and rear sides of the base plate 1 of the cutting device. A clamping cylinder 204 is fixedly installed on the top of the gantry frame 201, and the telescopic end of the clamping cylinder 204 passes through the gantry frame 201 and is fixedly connected to a clamping lifting plate 203. A clamping base plate 202 is fixedly installed inside the gantry frame 201 and parallel to the clamping lifting plate 203. Clamping claws 205 are fixedly installed on the side of the clamping base plate 202 and the clamping lifting plate 203 facing the fixed bracket 6. The height of the clamping base plate 202 is adapted to the height of the film material support plate 7.

[0032] By adopting the above technical solution, rotating the adjusting screw 402 can push the cleaning scraper 403 to move closer to the lower pressure plate 303, thereby making the cleaning scraper 403 and the cutting blade 307 close to each other. It should be noted that the cleaning scraper 403 and the cutting blade 307 are matched in shape. When the cutting blade 307 needs to be cleaned, the cleaning scraper 403 and the cutting blade 307 are close to each other. When the cutting blade 307 moves, the cleaning scraper 403 can clean the cutting blade 307. The telescopic rod 404 is used to guide the movement direction of the cleaning scraper 403.

[0033] Since the gantry 201 can slide on the base plate 1 of the cutting device, when longitudinal slitting is required, the gantry 201 moves towards the fixed support 6, and one end of the film material is located between the two sets of clamping claws 205. The clamping cylinder 204 is activated, and the clamping cylinder 204 pushes the clamping lifting plate 203 downward, so that the distance between the clamping lifting plate 203 and the clamping base plate 202 is shortened. At this time, the film material is clamped by the clamping claws 205. Then the gantry 201 moves away from the fixed support 6, which can pull the film material. When the film material is pulled, the film material comes into contact with the longitudinal cutter 5, and the film material can be slid.

[0034] Working principle: The membrane material passes between the membrane material support plate 7 and the cutting component 3. One end of the membrane material between the support plate 7 and the cutting component 3 is higher than the other end of the membrane material. The lifting cylinder 302 is activated, pushing the lower pressure plate 303 downwards. The lower pressure plate 303 presses the membrane material down. Since the lower pressure plate 303 is located to the right of the longitudinal cutter 5, when it descends, it moves the membrane material downwards and into contact with the longitudinal cutter 5. The other end of the membrane material is lower than the longitudinal cutter 5. The gantry 201 moves closer to the fixed support 6, and one end of the membrane material is positioned between the two sets of clamping claws 205. The clamping cylinder 204 is activated, pushing the clamping lifting plate 203 downwards, shortening the distance between the clamping lifting plate 203 and the clamping base plate 202. At this point, the membrane material is clamped by the clamping claws 205. Then, the gantry... The frame 201 moves away from the fixed support 6, which can pull the membrane material. When the membrane material is pulled, it comes into contact with the longitudinal cutter 5, which can cut the membrane material. Then, the servo motor 301 is started, which drives the adjusting screw 309 to rotate. This causes the sliding slider 308 on the adjusting screw 309 to slide inside the lower pressure plate 303, thereby driving the cutting blade 307 to move. When the cutting blade 307 moves, it can cut the membrane material, realizing the cutting of the membrane material in two directions. When it is necessary to clean the cutting blade 307, the adjusting screw 402 is rotated. The adjusting screw 402 can push the cleaning scraper 403 to move closer to the lower pressure plate 303. The cleaning scraper 403 and the cutting blade 307 are in close contact. When the cutting blade 307 moves, it can be cleaned by the cleaning scraper 403.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
