For example, the feeding device 1 may further comprise a discharge pipe 100, and the support shaft 30 and the sealing plate 20 may be located at the tail end of the discharge pipe 100. One end of the support shaft 30 is located in the inner hole of the screw shaft 10 and rotatably connected to the screw shaft 10, and the "connection" may be direct connection or indirect connection, which is not limited herein. The other end of the supporting shaft 30 extends to the mounting hole 21 and is in sealing connection with the sealing plate 20, so that impurities can be prevented from entering the inner hole of the screw shaft 10 from the outer side of the sealing plate 20, namely, the side, far away from the screw shaft 10, of the sealing plate 20, and the materials are prevented from being polluted.

Thus, the screw shafts 10 are disposed at a distance on one side of the sealing plate 20 and connected by the support shaft 30, whereby the screw shafts 10 can be incorporated. One end of the supporting shaft 30 extends into the inner hole and the other end of the supporting shaft 30 is connected with the sealing plate 20 in a sealing way, and on one hand, the supporting shaft 30 can play a role in supporting the screw shaft 10; on the other hand, both ends of the supporting shaft 30 can play a role in preventing foreign matters from entering the inner hole of the screw shaft 10, and the other end of the supporting shaft 30 and the sealing plate 20 do not rotate relatively, so that the abrasion can be prevented, the sealing effect on the screw shaft 10 can be further ensured, and the service life and the feeding effect of the feeding device 1 are improved.

In some embodiments, as shown in fig. 2, the feeding device 1 may further include: the first spacer 40 is disposed in the inner hole and is located outside the radial direction of the support shaft 30. The first spacer 40 may be an interference fit on the peripheral wall of the bore. By providing the first spacer 40, the screw shaft 10 and the support shaft 30 can be spaced apart in the radial direction of the screw shaft 10 to prevent the screw shaft 10 or the support shaft 30 from being worn out, to improve the service life of both.

Moreover, the two metal pieces are arranged at intervals, so that abrasion caused by friction is avoided, and further, metal impurities can be prevented from being generated, and the usability of the feeding device 1 in the lithium battery industry can be ensured.

In some embodiments, as shown in fig. 2, the feeding device 1 may further include: the second spacer 50 is sleeved on the support shaft 30 and rotatably matched with the first spacer 40. For example, the second spacers 50 may be adhered to the outer circumferential wall of the support shaft 30, and by providing the second spacers 50, even if one of the spacers is worn and the other one may continue to space the screw shaft 10 from the support shaft 30, further wear between the screw shaft 10 and the support shaft 30 may be prevented when the screw shaft 10 rotates, so that the service lives of both may be further improved.

In some embodiments, one of the first and second spacers 40, 50 is a ceramic sleeve and the other of the first and second spacers 40, 50 is a plastic bearing. For example, the first spacer 40 is a plastic bearing and the second spacer 50 is a ceramic bushing. So set up, because both are non-metal material, can be sliding friction when rotating the joining in marriage, consequently can not produce the card and die phenomenon. And moreover, the matching structure of the bearing and the shaft sleeve is simple, and the disassembly, the assembly and the maintenance are convenient. Of course, in other embodiments, the first spacer 40 and the second spacer 50 may be made of other non-metal materials, which is not limited herein.

For example, after the first spacer 40 is fixed to the first hole section 11, the inner diameter of the first spacer 40 is the same as the diameter of the second hole section 12, so that the same dimension of the inside in the axial direction of the inside of the screw shaft 10 can be ensured so as to ensure the coaxiality of the support shaft 30 and the screw shaft 10, and the perpendicularity of the screw shaft 10 and the sealing plate 20.

Further, as shown in fig. 2, the first spacer 40 has a burring 41 connected to the screw shaft 10. The flange 41 extends outwardly from the outer circumferential wall of the first spacer 40 in the radial direction and is connected to the end of the screw shaft 10, so that the contact area of the first spacer 40 and the screw shaft 10 can be increased to improve the stability of the connection therebetween to prevent the occurrence of the loosening thereof.

In some embodiments, as shown in fig. 1 and 2, the feeding device 1 may further include a baffle 60, the baffle 60 being fixed to the inner hole and located at a side of the support shaft 30 toward the center of the screw shaft 10. For example, the baffle 60 may be welded to the peripheral wall of the bore. The baffle 60 may be circular in cross-section. By providing the baffle 60, it is possible to prevent the material from being contaminated by entering the middle part of the axial direction of the inner hole through the gap between the first spacer 40 and the second spacer 50 or the screw shaft 10 when the feeding device 1 is operated, so as to further improve the feeding effect of the feeding device 1.

In some embodiments, as shown in fig. 3 and 4, the circumferential wall of the support shaft 30 is provided with an annular protrusion 31 extending in the circumferential direction of the support shaft 30, and the annular protrusion 31 abuts against the sealing plate 20, whereby the stability of the connection of the support shaft 30 and the sealing plate 20 can be improved, and positioning and mounting are facilitated. Meanwhile, the perpendicularity of the sealing plate 20 and the screw shaft 10 is guaranteed.

In some embodiments, as shown in fig. 4, the outer peripheral wall of the other end of the support shaft 30 has at least one recess 32. Thus, the outer peripheral wall of the portion of the support shaft 30 engaged in the mounting hole 21 is non-circular, so that the support shaft 30 can be conveniently and rotatably mounted in the mounting hole 21, thereby facilitating the convenience of mounting and fixing the support shaft 30 and the sealing plate 20.

In some embodiments, as shown in fig. 1 and 2, the feeding device 1 may further include: and the sealing gasket 70 is arranged on one side of the sealing plate 20 away from the screw shaft 10 and is in sealing connection with the sealing plate 20. By providing the packing 70, the sealing effect of the other end of the support shaft 30 and the sealing plate 20 can be ensured, and the perpendicularity of the second spacer 50, the support shaft 30 and the sealing plate 20 can be ensured. For example, the support shaft 30, the sealing pad 70, and the flange at the tail end of the feeder may be fixedly connected by bolts 80, and a backing plate 90 may be further provided on the side of the sealing pad 70 away from the screw shaft 10 to ensure reliability when being engaged with the bolts 80. At the same time, the rotation axis of the screw shaft 10 can be further ensured to be stable, and the condition of swing can be prevented.
