[0042] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0044] In industries such as lithium batteries and food and pharmaceuticals, the packaged materials are typically ultrafine powders. These materials require extremely strict control over equipment materials and foreign matter, and demand high cleanliness. If conventional material-cutting devices are used, the metal drive mechanism would be placed in the material channel, introducing foreign matter and contaminating the material. To address these issues, the applicant has creatively proposed a material-cutting device.

[0045] Reference Figures 1-3 As shown, the material cutting device in this embodiment includes a discharge pipe 1, a cutting disc 2, and a flexible rope 4. The discharge pipe 1 has a discharge port; one end of the cutting disc 2 is installed on the outer wall of the discharge pipe 1; one end of the flexible rope 4 is connected to the cutting disc 2, and the other end of the flexible rope 4 is connected to the outer wall of the discharge pipe 1 above the cutting disc 2. The flexible rope 4 can be stretched or shortened to drive the other end of the cutting disc 2 to rotate, thereby opening or closing the discharge port. According to this design, the discharge port can be opened or closed in a narrow pipe by the cooperation of the flexible rope 4 and the cutting disc 2, avoiding contamination of the material by foreign objects, ensuring the cleanliness of the material, and meeting the protection requirements of specific industries.

[0046] Specifically, in this embodiment, the flexible rope 4 can be pulled by a drive mechanism or manually to rotate the other end of the cutting disc 2. Preferably, the cutting device in this embodiment further includes a drive mechanism located on the outer wall of the discharge pipe 1 and above the cutting disc 2. One end of the flexible rope 4 is connected to the cutting disc 2, and the other end is connected to the drive mechanism. The drive mechanism can be a linear drive mechanism or a rotary drive mechanism 3, both of which can achieve the technical effect of pulling the flexible rope 4 to rotate the cutting disc 2. Therefore, the above solutions are all within the protection scope of this application. The linear drive mechanism can be a servo, stepper, cylinder, magnetic drive, hydraulic drive motor, or other linear drive mechanism with linear drive function along the axis of the discharge pipe 1.

[0047] To prevent contamination of the flexible rope 4 with materials, and to avoid reducing the service life of the flexible rope 4 due to material friction during the feeding process, refer to... Figure 1 , Figure 2 As shown, on a plane perpendicular to the axis of the discharge pipe 1, the projection of the flexible rope 4 in this embodiment is either separate from or tangent to the projection of the discharge port.

[0048] To facilitate guiding the path of the flexible rope 4 and prevent it from contacting the material during the feeding process, refer to... Figure 1 , Figure 2 As shown, the material cutting device in this embodiment also includes a guide structure 5 disposed on the discharge pipe 1, and the flexible rope 4 passes through the guide structure 5. Specifically, the guide structure 5 in this embodiment can be a guide plate 51, a guide ring, or a guide hook fixedly installed on the discharge pipe 1, or it can be a splicing ring plate 52 on the discharge pipe 1, or it can be a guide hole opened on the wall of the discharge pipe 1 for the flexible rope 4 to pass through. It should be noted that since the discharge pipe 1 is composed of multiple pipe sections spliced ​​together, a splicing ring plate 52 can be provided at the end of each pipe section. The splicing ring plate 52 can be used to splice two adjacent pipe sections together.

[0049] Reference Figure 1 , Figure 2 As shown, the cutting device in this embodiment also includes a counterweight 6 disposed on the flexible rope 4. The counterweight 6 is designed to dynamically adjust the tension of the flexible rope 4 to avoid it becoming too slack. When the drive mechanism adopts a rotary drive method, it can also make the flexible rope 4 more closely wound on the drive mechanism.

[0050] To avoid interference with material feeding caused by the cutting disc 2, refer to Figure 1 , Figure 2 As shown, when the discharge port is opened, on a plane perpendicular to the axis of the discharge pipe 1, the projection of the discharge port in this embodiment is either separate from or tangent to the projection of the cutting plate 2.

[0051] Specifically, in order to facilitate the rotation of the cutting disc 2 by the traction of the flexible rope 4, refer to Figure 1 , Figure 2 As shown, the flexible rope 4 in this embodiment includes a first flexible rope 41 and a second flexible rope 42, which are integrally formed. The first end of the first flexible rope 41 is connected to the cutting disc 2, and the second end of the first flexible rope 41 is connected to the first end of the second flexible rope 42. When the flexible rope 4 is pulled by a driving mechanism, the second end of the second flexible rope 42 is connected to the driving mechanism; when pulled manually, the second end of the second flexible rope 42 is connected to a person's hand. Optionally, a guide plate is disposed on the first flexible rope 41, and a counterweight 6 is disposed at the connection between the first flexible rope 41 and the second flexible rope 42. Optionally, the first flexible rope 41 includes multiple rope segments 411, the first ends of which are connected and connected to the second end of the second flexible rope 42, and the second ends of the multiple rope segments 411 are separate and all connected to the cutting disc 2. The flexible rope 4 is symmetrically arranged along the symmetrical surface of the discharge pipe 1.

[0052] Of course, this application is not limited to this. In other embodiments, the flexible rope 4 may only include the first flexible rope 41, the two ends of which are directly connected to the cutting disc 2 and the driving mechanism (or a human hand); or, in other embodiments, the first flexible rope 41 and the second flexible rope 42 are separately arranged, the second end of the first flexible rope 41 is connected to the counterweight 6, and the first end of the second flexible rope 42 is connected to the counterweight 6; or, in other embodiments, the first ends of the rope segments 411 are separated; or the flexible rope 4 is asymmetrically arranged along the symmetry plane of the discharge pipe 1. As long as the cutting disc 2 can be rotated when the flexible rope 4 is pulled and the flexible rope 4 does not contaminate the material, it is within the protection scope of this application. This application does not limit the specific structure of the flexible rope 4.

[0053] Specifically, in order to install the cutting disc 2 and the drive mechanism, refer to Figure 1 , Figure 2 As shown, the discharge pipe 1 in this embodiment includes a first pipe section 11 and a second pipe section 12. The material cutting disc 2 is rotatably mounted on the second pipe section 12, and the drive mechanism is fixedly mounted on the first pipe section 11. Both the first pipe section 11 and the second pipe section 12 can be a single sub-pipe section or a combination of multiple sub-pipe sections. The first pipe section 11 and the second pipe section 12 can be integrally formed or separately formed, all within the scope of protection of this application.

[0054] Reference Figure 5 and combined Figure 1 , Figure 2 As shown, when the material cutting device is installed on the packaging equipment for packaging materials, the discharge pipe 1 needs to extend into the packaging equipment pipe 8. Only a portion of the first pipe section 11 is located outside the packaging equipment pipe 8 (the drive mechanism can be installed on it to avoid contaminating the material). The distance between the outer wall of the discharge pipe 1 extending into the packaging equipment pipe 8 and the inner wall of the packaging equipment pipe 8 is relatively small, making it inconvenient for the material cutting disc 2 to rotate. Therefore, in this embodiment, the outer diameter of the first pipe section 11 is larger than the outer diameter of the second pipe section 12. Based on this design, when the discharge pipe 1 of this embodiment is installed inside the packaging equipment pipe 8, a suitable installation space is formed between the outer wall of the second pipe section 12 and the inner wall of the packaging equipment pipe 8, allowing the material cutting disc 2 installed on the second pipe section 12 to rotate smoothly under the traction of the flexible rope 4.

[0055] Optionally, refer to Figure 1 , Figure 2As shown, the second pipe section 12 includes a first body 121 and a second body 122 from top to bottom. The outer diameter of the first body 121 gradually decreases from top to bottom, while the outer diameter of the second body 122 remains unchanged. The material cutting tray 2 is installed on the second body 122. Of course, this application is not limited to this. The outer diameter of the second pipe section 12 can gradually decrease from top to bottom; or the outer diameter of the second pipe section 12 can remain unchanged and be smaller than the outer diameter of the first pipe section 11. Both of these can create an installation space at the second pipe section 12, and both are within the protection scope of this application.

[0056] Preferably, refer to Figure 1 , Figure 2 As shown, in this embodiment, the second pipe section 12 is an eccentric pipe, and the material cutting disc 2 is rotatably mounted on the eccentric side of the second pipe section 12. The horizontal distance between the outer wall of this eccentric side and the outer wall of the first pipe section 11 is greater than the horizontal distance between the outer wall of the opposite eccentric side of the second pipe section 12 and the outer wall of the first pipe section 11. This design facilitates the installation of the material cutting disc 2 and avoids bridging during the solid material feeding process.

[0057] Specifically, when the driving mechanism in this embodiment adopts the rotary driving mechanism 3, refer to Figure 3 , Figure 4 As shown, the driving mechanism in this embodiment includes a rotary drive component 31 and a roller 32. The roller 32 is fixedly mounted on the output shaft of the rotary drive component 31, and a flexible rope 4 is connected to the roller 32. When the rotary drive component 31 drives the roller 32 to rotate, the flexible rope 4 can be wound around the roller 32 or released from the roller 32. The rotary drive component 31 can be a swing cylinder, a DC motor, an AC asynchronous motor, an AC synchronous motor, or other rotary drive components with rotary driving functions.

[0058] Optionally, refer to Figure 4 As shown, in this embodiment, the roller 32 has a circumferentially formed receiving groove 321, and the drive mechanism also includes a limiting shaft 33 arranged axially along the output shaft. The limiting shafts 33 are spaced apart in the receiving groove 321 circumferentially along the roller 32. According to this design, the flexible rope 4 can be confined within the receiving groove 321 to prevent it from loosening.

[0059] To facilitate the installation of the drive mechanism on the outer wall of the discharge pipe 1, refer to Figure 3 , Figure 4 As shown, the material cutting device in this embodiment also includes a mounting bracket 7, which is fixedly installed on the outer wall of the discharge pipe 1, and the drive mechanism is fixedly installed on the mounting bracket 7.
