[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-5 As shown, the etherification equipment for cellulose production includes a box 1 and a plurality of blades 5 for fiber breaking. The box 1 is a box of the prior art proposed in the background technology, which is used for fiber etherification, and as shown in FIG. Figure 2As shown, one side of the box body 1 is open, and the blade 5 is used to cut the fiber short during fiber etherification to ensure the etherification effect. A rotating rod 4 is rotatably connected to the inner wall of the box body 1 on one side, and the rotation of the rotating rod 4 can be achieved by installing a motor of the prior art outside the box body 1, and using the motor to drive the rotating rod 4 to rotate. One end of the rotating rod 4 is in the shape of a rectangular column and is hollow, and the hollow open end faces the opening on the side of the box body 1. The rectangular columnar part of the rotating rod 4 is sleeved with a sleeve 3 for installing the blade 5, and the sleeve 3 is driven to rotate by the rotation of the rotating rod 4, thereby realizing the rotation of several blades 5. One end of the sleeve 3 is rotatably connected to the inner wall of the box body 1, and the outer wall of the other end is sleeved with a threaded connection with the inner wall of the box body 1 and is divided on the same side as the nut 16. The sealing ring 2 of the cloth can be used to ensure that the rotating rod 4 drives the sleeve 3 and the blade 5 to rotate relative to the sealing ring 2. When the limit processing in the box body 1 is realized, the sealing ring 2 is used to prevent the fiber from escaping from the box body 1, and a spring rod 6 is fixedly connected to one end of the inner wall of the rotating rod 4, and a screw rod 7 is fixedly connected to the telescopic end of the spring rod 6. A plurality of conical blocks 8 are fixedly connected to the screw rod 7. The inner side walls around the rotating rod 4 are all provided with connecting plates 9. One side of the connecting plate 9 is fixedly connected to a plurality of plug-in blocks 10 that penetrate the inner wall of the rotating rod 4 and are used to be plugged into the inner wall of the sleeve 3, and the other side is fixedly connected to an inclined block 14 that is slidably connected to the inclined surface of the conical block 8. A nut 16 that is threadedly connected to the screw rod 7 is rotatably connected in the hollow at one end of the rotating rod 4. Figure 4 As shown, the position of the sleeve 3 at the plug block 10 is a hollow setting for the plug block 10 to pass through. Therefore, after the sleeve 3 is completely installed on the rotating rod 4, the characteristic that the screw rod 7 cannot rotate due to the spring rod 6 is utilized. Therefore, by rotating the nut 16, the threaded screw rod 7 can drive the conical block 8 on its surface to move toward the spring rod 6, and compress the spring rod 6. During the movement of the conical block 8, its inclined surface portion will contact and slide with the inclined surface of the inclined block 14, thereby enabling the inclined block 14 to drive the connecting plate 9 and the plug block 10 to move toward the inner wall of the rotating rod 4, that is, the plug block 10 is moved to the corresponding hollow position on the insertion sleeve 3, so that the position of the sleeve 3 and the blade 5 can be fixed, and during the fixing process, the position where the driving nut 16 rotates is located at the side opening end of the box body 1, thereby ensuring safety during the fixing process.

[0024] Further discussion, in order to prevent the blade 5 from touching the inner wall of the box body 1 during installation: the outer wall of the sleeve 3 is plugged with a plurality of mounting seats 11 distributed in a circular array and used to mount the handle of the blade 5, and a connecting block 12 located in the sleeve 3 is fixedly connected between two adjacent mounting seats 11, and a pin shaft 15 fixedly connected to the inner wall of the sleeve 3 is penetrated through the connecting block 12. The pin shaft 15 is used to ensure that the connecting block 12 can only slide relative to the inner wall of the sleeve 3, thereby realizing that the mounting seat 11 connected to the connecting block 12 can only slide in a fixed direction, that is, by installing The seat 11 slides to drive the blade 5 installed thereon to move, that is, to ensure that the tip of the blade 5 does not contact the inner wall of the box body 1 during the installation and fixing of the sleeve 3. The plurality of mounting seats 11 are divided into a plurality of groups, and the plurality of groups of mounting seats 11 are respectively distributed around the rotating rod 4. The outer walls around the rotating rod 4 are slidably connected to two connecting strips 18. A push block 13 is fixedly connected between the two connecting strips 18 and at a position close to each mounting seat 11. The contact surface of the push block 13 and the mounting seat 11 is an inclined surface position and is slidably connected. The surface of the push block 13 is driven by the movement of the connecting strip 18. The push block 13 moves, and the inclined surface of the push block 13 is used to push the mounting seat 11 at the corresponding position to move, and when the push block 13 moves in the direction away from the opening side of the box body 1, the mounting seat 11 can be pushed to drive the blade 5 to move to fit with the inner wall of the box body 1, that is, after the position of the sleeve 3 is fixed, the blade 5 is installed to the corresponding position in the box body 1, and the outer wall around the rotating rod 4 is fixedly connected to the guide rail 19 slidably connected to the two connecting strips 18, and the inner wall of the sleeve 3 is sleeved with a connecting ring 20 fixedly connected to the connecting strips 18 around the rotating rod 4, and the guide rail 19 is arranged to ensure The connecting strip 18 can only slide along the center line direction of the sleeve 3, and the connecting ring 20 is set to ensure that several connecting strips 18 can move synchronously. The end face of the connecting ring 20 is rotatably connected to a threaded ring 17 which is threadedly connected to the inner wall of the sleeve 3 and distributed on the same side as the sealing ring 2. By rotating the threaded ring 17 and using the threaded ring 17 to rotate relative to the connecting ring 20 and move in the box body 1, the connecting ring 20 can be pushed to move, thereby realizing that all the connecting strips 18 simultaneously drive the push blocks 13 at corresponding positions to move, that is, the blades 5 in the box body 1 can be moved simultaneously.

[0025] Working principle: insert the sleeve 3 into the rotating rod 4 until one end of the sleeve 3 fits against the inner wall of the closed side of the box body 1, and then rotate the nut 16 to enable the screw rod 7 to overcome the elastic force of the spring rod 6 and move, and the screw rod 7 drives the conical block 8 on its surface to move toward the spring rod 6, and the inclined surface of the conical block 8 contacts and slides with the inclined surface of the inclined block 14, so that the inclined block 14 drives the connecting plate 9 and the plug block 10 to move toward the inner wall of the rotating rod 4, that is, the plug block 10 moves to the corresponding hollow part on the insertion sleeve 3, so that the position of the sleeve 3 and the blade 5 can be fixed, and then the position of the blade 5 is adjusted to extend to fit the inner wall of the box body 1, and finally the sealing ring 2 is installed, and the fiber is poured into the box body 1, and the sleeve 3 is driven to rotate by the rotating rod 4, so that the blade 5 can be rotated, that is, the fiber etherification is realized.

[0026] The wiring diagram of the motor in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the motor are not explained in detail.
