[0017] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figs. 1-3 The fabric tray anti-loosening support assembly structure shown for a vertical centrifuge includes a fabric tray 2 connected to the top of the central sleeve 1 of the drum. The fabric tray 2 includes an annular top plate 201 and a conical side plate 202. The lower diameter of the side plate 202 is larger than the upper diameter. The top plate 201 is connected to the top of the side plate 202. The central sleeve 1 and the top plate 201 are both sleeved on the top of the centrifuge shaft 3. The top plate 201 is threaded to the top of the central sleeve 1 of the drum via a nut 4 at the top of the shaft 3. Multiple circumferentially distributed positioning plates 5 are vertically connected to the inner wall of the fabric tray 2. The outer edge of the top of the central sleeve 1 has slots 6 corresponding to the positioning plates 5. The positioning plates 5 are inserted into the slots 6 one by one, so that the fabric tray 2 rotates synchronously with the central sleeve 1, thereby overcoming the technical problem of relative rotation between the fabric tray 2 and the central sleeve 1 of the drum when the fabric tray 2 rotates at high speed to spread the fabric.

[0019] In this embodiment, preferably, a threaded sleeve 7 is fixedly connected to the upper surface of the top plate 201 of the fabric distribution tray 2. The threaded sleeve 7 is coaxially arranged with the rotating shaft 3 and located outside the nut 4. The outer wall of the threaded sleeve 7 is provided with external threads. A locking nut 8 is connected to one end of the threaded sleeve 7 near the fabric distribution tray 2, and a support tube 9 is threadedly connected to the other end of the threaded sleeve 7 away from the fabric distribution tray 2. An inverted cone 10 is fixedly connected to the top of the support tube 9, and the lower edge of the cone 10 extends above the side plate 202 of the fabric distribution tray 2. The cone 10 covers the nut 4 to prevent material from contaminating the nut 4.

[0020] As further improvement of the above technical solution, in the embodiment, the external threads on the outer wall of the threaded sleeve 7 include left-handed threads 11 and right-handed threads 12, which respectively extend from both ends of the threaded sleeve 7 to the middle and finally meet. In the embodiment, the threads near the one end of the threaded sleeve 7 approaching the top plate 201 are right-handed threads, and the outer wall of the support pipe 9 is provided with right-handed threads with the same thread rotation direction and the same pitch as the threads near the one end of the threaded sleeve 7 approaching the top plate 201. The locking nut 8 includes a first connecting part 801 threadedly connected with the threaded sleeve 7 and a second connecting part 802 connected with the support pipe 9, and the second connecting part 802 is integrally formed at the top end of the first connecting part 801.

[0021] The working process of the utility model is: assembling the cloth distribution disc according to the structure shown in the figure, when the centrifuge works, the material falls from above the conical hopper 10 to the conical hopper 10, the conical hopper 10 guides part of the material flow to the side plate 202 of the cloth distribution disc 2, and part of the material is directly thrown by the conical hopper 10. Fig. 1 When the centrifuge works, the material falls from above the conical hopper 10 to the conical hopper 10, the conical hopper 10 guides part of the material flow to the side plate 202 of the cloth distribution disc 2, and part of the material is directly thrown by the conical hopper 10.

[0022] The cloth distribution disc 2 rotates synchronously with the center sleeve 1 under the cooperation of the positioning piece 5 and the slot 6, eliminates the risk of loosening of the nut 4 caused by the rotation of the cloth distribution disc 2 relative to the center sleeve 1, and improves the working stability of the cloth distribution disc 2 and the whole rotating drum.

[0023] The support pipe 9 is limited by the left-handed threads 11 and the right-handed threads 12 at the same time, so the support pipe 9 will not loosen in any rotating direction of the rotating drum, which also ensures that the conical hopper 10 will not loosen.

[0024] The above embodiments only exemplarily illustrate the principles and effects of the present application, and part of the applied embodiments, and are not used to limit the present application; it should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
