[0039] Specifically, after the adjusting assembly 50 drives the other end of the flexible pipe 40 to correspond to one of the outlet holes 13, the extension structure 30 presses the other end of the flexible pipe 40 at the outlet hole 13 through the fixed plate 20.

[0040] Compared with the prior art, the adjusting assembly 50 arranged on the fixed plate 20 drives the other end of the flexible pipe 40 to correspond to each outlet hole 13 respectively, so that the material entering the inlet hole 12 can be guided into the corresponding outlet hole 13 through the flexible pipe 40, thereby ensuring the material distribution effect. The other end of the flexible pipe 40 can correspond to any one of the outlet holes 13, the extension structure 30 drives the fixed plate 20 to move, and then the other end of the flexible pipe 40 can be pressed at the outlet hole 13, so that the sealing effect can be ensured and the negative pressure conveying can be adapted. In addition, after the fixed plate 20 releases the pressing on the flexible pipe 40, the frictional resistance of the other end of the flexible pipe 40 during the transfer process can also be reduced, and the practicability is high.

[0041] It should be noted that the extension structure 30 can be a kind of air cylinder and electric push rod, or other structures capable of realizing linear driving. In order to ensure the stable movement of the fixed plate 20, the extension structure 30 can be provided as two, and the two extension structures 30 can be arranged in a ring shape and spaced apart around the base circle axis where each outlet hole 13 is located.

One end of the hose 42 is connected with the feeding hole 12, and the other end is connected with the through hole.

[0043] The slide plate 41 can ensure the connection of the bottom of the hose 42, strengthen the other end of the hose 42, and the through hole on the slide plate 41 can also ensure the stable correspondence with any one of the discharging holes 13, thereby facilitating the connection of the adjusting assembly 50 and ensuring the material conveying effect.

[0044] In addition, the fixing plate 20 can be a circular plate, and the fixing plate 20 has an overlapping area with the slide plate 41, which can ensure the pressing of the fixing plate 20 on the slide plate 41.

[0045] In some embodiments, the slide plate 41 can adopt the structure as shown in Figure 3 . Referring to Figure 3 , the slide plate 41 is provided with a first fixing ring 411 for fixedly connecting the other end of the hose 42 and communicating with the through hole. The first fixing ring 411 can ensure the sleeving of the other end of the hose 42, thereby ensuring the stable connection of the hose 42 with the slide plate 41.

[0046] In some embodiments, the slide plate 41 can adopt the structure as shown in Figure 2 and Figure 3 . Referring to Figure 2 and Figure 3 , the slide plate 41 is a circular plate, which can facilitate manufacturing and also facilitate movement between the discharging holes 13.

[0047] It should be noted that the bottom end of the slide plate 41 can be provided with a sealing rubber ring.

Referring to Figures 2 to 3 , the bottom surface of the accommodating cavity 11 away from the feeding hole 12 is provided with an annular groove 15 for sliding of the slide plate 41. Each discharging hole 13 is located on the bottom surface of the annular groove 15.

[0049] The annular groove 15 can provide a space for limiting the sliding of the slide plate 41, and further ensure that the through holes on the slide plate 41 correspond to the discharging holes 13 respectively.

[0050] It should be noted that the mounting box 10 can be a conical structure, the feeding port is located at the small-diameter end, and a circular sealing cover is provided at the large-diameter end, and the annular groove 15 is located on the sealing cover, which can be seen from Figure 3The sealing cap is located on the side wall of the accommodating cavity 11, which is the bottom surface of the accommodating cavity 11 away from the feed hole 12.
