Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As shown in Figures 1 to 3 , a reverse osmosis membrane device provided by the present invention includes a conveying device 1, a lifting device 2, a lifting plate 3, a tool rest 4, a motor 5, and a cutting tool 6.

There are two tool rests 4 located on the front side and the rear side of the bottom of the lifting plate 3. The motor 5 is fixedly installed on the outside of the tool rest 4. The cutting tool 6 is fixedly connected to the surface of the output shaft of the motor 5. A moving block 7 is fixedly connected to the top of the tool rest 4. A lead screw 8 is threadedly connected inside the moving block 7. Support assemblies 9 are movably connected to the front side and the rear side of the surface of the lead screw 8.

A support plate 92 is movably connected to the surface of the bearing 91. The top of the support plate 92 is fixedly connected to the lifting plate 3.

[0024] As a technical optimization scheme of the present invention, by setting the support assembly 9, the support plate 92 is fixedly installed with the lifting plate 3 and the support plate 92, and then the lead screw 8 is movably installed with the support plate 92 through the bearing 91, so that the lead screw 8 can stably rotate through the bearing 91 and the support plate 92.

[0025] Referring to Figure 3 , the distance display mechanism 10 includes an infrared distance sensor 101. The infrared distance sensor 101 is fixedly connected to the left side of the front moving block 7. A reflector 102 is fixedly connected to the left side of the rear moving block 7.

A display 104 is fixedly connected to the bottom of the front of the lifting device 2. The display 104 is electrically connected to the controller 103 through a wire.

[0026] As a technical optimization solution of the utility model, by setting a distance display mechanism 10, when the operator adjusts the distance between the two cutting knives 6, the transmitter of the infrared ranging sensor 101 emits an infrared signal of a specific frequency. When these signals encounter the reflector 102, they will be reflected and returned to the receiver, and then the transmitted signal is transmitted to the controller 103 through a wire, and then the controller 103 processes the signal, and then the controller 103 converts the processed signal into data and transmits it to the display 104, so that the display 104 displays the distance value, so that the operator can easily observe the distance between the two cutting knives 6, thereby ensuring the cutting effect.

[0027] refer to Figure 3 The limiting assembly 11 includes a limiting block 111 , which is fixedly connected to the top of the moving block 7 , and a limiting groove 112 for cooperating with the limiting block 111 is formed at the bottom of the lifting plate 3 .

[0028] As a technical optimization solution of the utility model, by setting a limit assembly 11, when the rotating screw 8 drives the moving block 7 to move, the moving block 7 will drive the limit block 111 to move inside the limit groove 112, so that the limit block 111 and the limit groove 112 can limit and guide the moving block 7, thereby preventing the moving block 7 from rotating when the screw 8 rotates.

[0029] refer to Figure 3 A rotating block 12 is fixedly connected to the surface of the screw rod 8 , and the diameter of the rotating block 12 is greater than the diameter of the screw rod 8 .

[0030] As a technical optimization solution of the utility model, by providing the rotating block 12, the rotating block 12 can provide a fulcrum for the operator when using the screw rod 8, thereby making it easier for the operator to rotate the screw rod 8.

[0031] refer to Figure 3 A protective cover 13 is attached to the surface of the rotating block 12, and the material of the protective cover 13 is natural rubber.

[0032] As a technical optimization solution of the utility model, by providing a protective cover 13, the protective cover 13 is adhered to the surface of the rotating block 12, so that the protective cover 13 protects the operator's hands and avoids scratches on the operator's hands.

[0033] refer to Figure 3 The surface of the protective cover 13 is provided with anti-skid patterns 14, and a plurality of anti-skid patterns 14 are arranged and are distributed at equal distances in a rectangular shape.

[0034] As a technical optimization solution of the present utility model, by providing the anti-slip pattern 14, the anti-slip pattern 14 can increase the friction between the operator's hand and the protective sleeve 13, avoiding the situation of slipping when the operator uses the rotating block 12 through the protective sleeve 13.

[0035] The working principle and usage process of the present utility model: When in use, when the operator needs to cut a workpiece, the operator winds the workpiece from right to left around the conveying roller of the conveying device 1, then drives the cutting knife 6 to rotate by the output end of the motor 5, and then the operator controls the lifting device 2 to drive the lifting plate 3 to move downward, so that the lifting plate 3 drives the cutting knife 6 to contact the workpiece. By continuously conveying the workpiece through the conveying device 1, the cutting knife 6 performs edge cutting work on the workpiece. When the operator needs to cut workpieces of different widths, the operator rotates the lead screw 8 through the rotating block 12, so that the lead screw 8 rotates through the bearing 91 and the support plate 92, and then the rotating lead screw 8 drives the moving block 7 to move through the limit block 111 and the limit groove 112, and further the moving block 7 drives the cutting knife 6 through the tool rest 4 to move closer to or away from each other, so that the cutting lengths of the two cutting knives 6 for the workpiece are approximately equal, ensuring the cutting quality. When the operator adjusts the distance between the two cutting knives 6, the transmitter of the infrared distance measuring sensor 101 emits infrared signals of a specific frequency. When these signals encounter the reflector 102, they will be reflected and returned to the receiver, and then the transmitted signals are transmitted to the inside of the controller 103 through the wire. Then the controller 103 processes the signals, and then the controller 103 converts the processed signals into data and transmits them to the inside of the display 104, so that the display 104 displays the distance value, and further the operator can conveniently observe the distance between the two cutting knives 6, ensuring the cutting effect.

[0036] In summary: For this reverse osmosis membrane device, by providing the lead screw 8, the lead screw 8 can drive the cutting knives 6 to move closer to and away from each other, thereby ensuring that the cutting lengths of the two cutting knives 6 for the workpiece are approximately equal, ensuring the cutting quality. At the same time, the distance display mechanism 10 enables the operator to conveniently observe the adjusted distance between the two cutting knives 6, solving the problem that the above-mentioned device cannot adjust the two tool heads simultaneously, and the workpiece will remain in the centered state through the limiting structure, resulting in inconsistent cutting lengths on both sides of the workpiece, thus affecting the cutting quality.
