Description

Technical Field

[0001] The invention relates to the field of ceramic nanofiltration membranes, in particular to a cutting and positioning device for producing ceramic nanofiltration membranes. Background Art

[0002] Ceramic nanofiltration membrane is a kind of filter membrane material used to separate solid particles, bacteria, viruses and other tiny substances. It is usually made of ceramic material, with high porosity and high temperature resistance. Ceramic nanofiltration membrane can be used in water treatment, food and beverage processing, pharmaceutical manufacturing and other fields, playing an important role in filtration and separation; ceramic nanofiltration membrane needs to be cut during the production process. When the existing ceramic nanofiltration membrane production and cutting device is used, the first wedge block is squeezed outward by the cutting tool holder, so that the push block is retracted into the second slide slot, so that the ceramic nanofiltration membrane is easily loaded, and then the push block is ejected under the elastic action of the second spring, so that the cut ceramic nanofiltration membrane is easily unloaded, thereby improving work efficiency. The second wedge-shaped block is made to pop out of the first slide groove under the elastic action of the first spring, thereby blocking one end of the ceramic nanofiltration membrane, and then the pressure plate is pressed on the other end of the ceramic nanofiltration membrane under the elastic action of the third spring, thereby clamping the ceramic nanofiltration membrane, thereby facilitating the cutting of the ceramic nanofiltration membrane in the later stage; in actual use, the push block is popped out to facilitate the unloading of the cut ceramic nanofiltration membrane, but when the push block pushes the cut ceramic nanofiltration membrane for unloading, the cut ceramic nanofiltration membrane is still in a clamped state under the elastic action of the third spring, so that the cut surfaces of the ceramic nanofiltration membrane are tightly pressed together. When the ceramic nanofiltration membrane is pushed, greater friction will occur between the cut surfaces of the ceramic nanofiltration membrane, which will cause wear to the cut surfaces of the ceramic nanofiltration membrane. For this reason, the present invention provides a cutting and positioning device for ceramic nanofiltration membrane production. Summary of the invention

[0029] Working principle of the present invention: when in use, the moving table 304 and the limit block 1 302 fit each other, at this time, the distance between the cutting table 1 201 and the cutting table 2 307 matches the cutting knife 14, the bottom of the cutting table 1 201 and the top of the support table 202 fit each other, the lifting limit block 702 is in the middle position of the inner cavity of the connecting sleeve 703, and the reset guide assembly 10 is in a relatively stable state. At this time, the downward movement of the lifting rod 701 will not affect the auxiliary discharge assembly 7; at the same time, there is a certain distance between the clamping block 16 and the cutting table 1 201 to the cutting table 2 307; before formal cutting, according to the size of the ceramic nanofiltration membrane to be cut, the distance between the positioning plate 204 and the knife groove (the knife groove is the distance between the cutting table 1 201 and the cutting table 2 307) should be adjusted to ensure that the size of the ceramic nanofiltration membrane cut each time meets the requirements; During the operation, the operator places the ceramic nanofiltration membrane to be cut on the top between the cutting table 1 201 and the cutting table 2 307, and one end of the ceramic nanofiltration membrane to be cut contacts the positioning plate 204, and starts the hydraulic cylinder 5 to drive the lifting plate 6 to move downward. The downward movement of the lifting plate 6 will simultaneously drive the cutting knife 14 and the two groups of clamping blocks 16 to move downward. The rubber pads 17 at the bottom of the two groups of clamping blocks 16 will first contact the ceramic nanofiltration membrane, so that the two groups of clamping blocks 16 will not be able to move downward. As the lifting plate 6 continues to move downward, the spring 18 is squeezed and The squeezed spring 18 applies pressure to the clamping block 16, so that the ceramic nanofiltration membrane is stably fixed on the top of the cutting table 1 201 to the cutting table 2 307, and then the cutting knife 14 moves downward to complete the cutting. It should be noted that in the process of the lifting plate 6 moving downward to drive the cutting knife 14 to complete the cutting, the lifting limit block 702 also moves downward along the inner cavity of the connecting sleeve 703, but the bottom of the lifting limit block 702 never contacts the inner wall of the connecting sleeve 703, and thus in the cutting process, it will not affect the auxiliary discharge assembly 7; After the cutting is completed, the hydraulic cylinder 5 is started to drive the lifting plate 6 to move up and reset. The lifting plate 6 moving up and resetting will drive the cutting knife 14 and the two sets of clamping blocks 16 to move up and reset, so that the cutting knife 14 and the two sets of clamping blocks 16 leave the ceramic nanofiltration membrane. Then, the hydraulic cylinder 5 is started again to drive the lifting plate 6 to move up. The lifting plate 6 continues to move up and drives the lifting rod 701 to move up. The lifting rod 701 moves up and drives the lifting limit block 702 to move up in the inner cavity of the connecting sleeve 703. When the top of the lifting limit block 702 contacts the connecting sleeve 703, the lifting limit block 702 is moved upward. After the inner wall of the sleeve 703 is touched, the lifting rod 701 moves upward to drive the connecting sleeve 703 to move upward, the connecting sleeve 703 moves upward to drive the lifting platform 704 to move upward, the lifting platform 704 moves upward to drive the rotating plate 710 to move upward, so that the bottom of the rotating frame 711 gradually contacts the inner wall of the rotating plate 710, and in this process, the lifting platform 704 moves upward to drive the rack 705 to rotate, the rack 705 rotates to drive the rotating shaft 707 to rotate, the rotating shaft 707 rotates and transmits the two sets of sprockets 708 and the chain 709. Under the action, the screw rod 301 is driven to rotate, and the rotation of the screw rod 301 drives the moving platform 304 along the guide rod 306 away from the limit block 302, so that the cutting platform 2 307 is away from the cutting platform 201, and then the ceramic nanofiltration membranes of the cutting platform 2 307 and the cutting platform 201 are separated from each other, so as to avoid that the ceramic nanofiltration membrane on the cutting platform 201 is not affected when the ceramic nanofiltration membrane on the cutting platform 207 is unloaded, and the cut surfaces of the two ceramic nanofiltration membranes are not rubbed against each other during the unloading process. After the bottom of the rotating frame 711 contacts the inner wall of the rotating plate 710, the lifting platform 704 continues to move upward, which will drive the rotating frame 711 to move upward, thereby rotating the cutting table 201 until the cutting table 201 contacts the material guide frame 20. At this time, the cutting table 201 is in an inclined state, so that the ceramic nanofiltration membrane on the cutting table 201 rolls down along the slope of the material guide frame 20 and finally stays in the material guide frame 20. Then the operator takes out the ceramic nanofiltration membrane in the material guide frame 20; When the unloading work is completed, the hydraulic cylinder 5 is started again to drive the lifting plate 6 to move down and reset. As the lifting platform 704 continues to move upward, the strong spring 2 1004 is squeezed and the strong spring 1 1003 is stretched. In the process of the lifting plate 6 driving the lifting limit block 702 to reset, the strong spring 2 1004 and the strong spring 1 1003 will drive the lifting platform 704 to move down and reset under the elastic force of the strong spring 2 1004 and the strong spring 1 1003, thereby causing the cutting table 1 201 to flip and reset, and the cutting table 2 307 to move and reset; at this time The starting motor 312 drives the second screw 311 to rotate. The rotation of the second screw 311 will drive the moving frame 309 to move. The movement of the moving frame 309 will drive the push block 310 to move. The push block 310 will push the ceramic nanofiltration membrane on the cutting table 2 307 to move until the end of the ceramic nanofiltration membrane away from the push block 310 contacts the positioning block 206 for the next cutting.
