Description

Technical Field

[0001] The utility model relates to the technical field of ceramic nanofiltration membrane equal-division cutting, and more specifically to an equal-division cutting device for ceramic nanofiltration membrane production. Background Art

[0002] Ceramic nanofiltration membranes have the characteristics of resistance to organic solvents, high temperature resistance, acid and alkali resistance, high mechanical strength, large flux and long life. They are increasingly widely used in industries such as chemical, energy, electronics, food and medicine. Ceramic nanofiltration membranes need to be cut into equal parts during the production process. Therefore, an equal cutting device for ceramic nanofiltration membrane production is proposed.

[0003] Most ceramic nanofiltration membranes in the equal-division cutting devices on the market are fixed with a bench vise. This method is cumbersome when loading and unloading materials, resulting in low work efficiency.

[0004] In response to the above problems, application number 202 22080 30, the application name is a kind of equal-division cutting device for ceramic nanofiltration membrane production, which is recorded and includes a body and a cutting tool holder, the bottom inner wall of the body is provided with a first slide groove, and a second wedge block is slidably connected in the first slide groove, the bottom of the second wedge block is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to the bottom inner wall of the first slide groove, and a positioning column is slidably inserted into the inner wall of one side of the body, one end of the positioning column is fixedly connected to a pressure plate, and the outer wall of the positioning column is sleeved with a third spring, one end of the third spring is fixedly connected to the pressure plate, and the other end of the third spring is fixedly connected to the body. The device squeezes the first wedge block outward through the cutting tool holder, so that the push block is retracted into the second slide groove, which facilitates the loading of the ceramic nanofiltration membrane, and then the push block is popped out under the elastic action of the second spring, which facilitates the unloading of the cut ceramic nanofiltration membrane and improves work efficiency.

[0005] Although the device has many beneficial effects, the following problems still exist: although the device can make it easier to load and unload ceramic nanofiltration membranes, in actual use, the second wedge block is ejected from 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 subsequent cutting of the ceramic nanofiltration membrane. Such a fixing method often lacks a certain fixing effect at the cutting point and has a poor limiting effect, which makes it easy for the material to move during the cutting process, thereby affecting the cutting accuracy, and when the cutting tool applies pressure to the material, the cutting position is unstable, resulting in uneven cutting of the material, increasing the safety risks of the cutting tool and the operator, and when the ceramic nanofiltration membrane needs to be cut into multiple sizes, the adjustment is also cumbersome, which undoubtedly causes great trouble to the actual use;

[0006] In addition, the cutting knife occupies a very important position during use, and the cutting knife often produces greater wear during long-term use. The existing replacement method is to fix the cutting knife with screws or bolts, which requires personnel to use professional tools to disassemble and replace it when replacement is needed. This not only increases the labor intensity of personnel, but also reduces the replacement efficiency of personnel.

[0007] In view of this, we propose an equal-division cutting device for ceramic nanofiltration membrane production. Utility Model Content

The screw motor 1 can be used to drive the two moving platforms to move close or far away, so that it can better cut the ceramic nanofiltration membrane into equal parts of various sizes. Secondly, in the process of adjusting the distance between the two moving platforms, due to the effect of the multiple guide connecting frames, the knife seats 2 of the multiple cutting assemblies 1 can be moved synchronously, making it more convenient to adjust to various equal cutting needs, thereby improving its flexibility of use. Secondly, after the adjustment, the screw motors 2 on the outer walls of the multiple moving platforms and the fixed platform can be used to respectively drive the moving frames carrying rubber pads to limit and fix the cutting position, effectively avoiding the deviation of the material during the cutting process or the splashing caused by the uneven cutting of the cutting knife, thereby improving the cutting accuracy and ensuring the safety of the cutting.

[0021] When the cutting knife needs to be replaced, it is only necessary to rotate the threaded protrusion so that the threaded protrusion can release the pressure on the limit block, and then use the action of multiple springs to drive the limit block to retract, so that the limit block is away from the limit of limit hole 1 and limit hole 2. Finally, the cutting knife can be moved down to be taken out, and the opposite is true during installation, which effectively improves the replacement efficiency of personnel, makes replacement simpler and more convenient, and reduces the labor intensity of personnel replacement.
