Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, a spiral discharging bearing buffering structure provided in an embodiment of the present invention includes a rotating shaft 201, a bidirectional spiral discharging roller 202 disposed on the rotating shaft 201, and bearings 203 disposed on two sides of the rotating shaft 201, where the rotating shaft 201 can drive the bidirectional spiral discharging roller 202 to rotate, so as to push a material to move in a direction away from the bidirectional spiral discharging roller 202 in an axial direction of the bidirectional spiral discharging roller 202.

In this embodiment, the spiral discharging bearing buffering structure of this embodiment further includes a buffer sleeved on the rotating shaft 201, and the buffer is disposed between the bidirectional spiral discharging roller 202 and the bearing 203 and fixed on the rotating shaft 201 to limit the material from entering the corresponding position of the bearing 203. That is, the present embodiment uses the buffer to block the material guided to the bearing 203 when the bidirectional helical discharging roller 202 is operated, so as to prevent the material from intruding into the bearing 203.

Specifically, the buffer of the present embodiment includes a buffer casing 10, and a cover plate 20 disposed at one end of the buffer casing 10, the other end of the buffer casing 10 abuts against a bearing cover 204 of a bearing 203, wherein the cover plate 20 abuts against an outer peripheral wall of a rotating shaft 201, and is engaged with the buffer casing 10 and formed with a buffer chamber 101.

The cover plate 20 of the present embodiment is partially extended out of the buffer casing 10, wherein the cover plate 20 is bent toward the bearing 203 at the portion extended out of the buffer casing 10 and is formed with a blocking disc 21, and the blocking disc 21 can block the material from entering the position of the buffer casing 10. That is, according to the present embodiment, the material can be blocked from entering the position of the damper housing 10 by the blocking disk 21 of the cover plate 20, and the material can be prevented from entering the bearing 203. It should be noted that the material guided to the buffer case 10 by the bidirectional helical discharge roller 202 can move along the disc surface where the barrier disc 21 is located toward the direction away from the buffer case 10.

It is understood that the buffer case 10, the cover plate 20 and the barrier disc 21 of the present embodiment are connected as an integral structure.

In addition, the chamber diameter of the buffer chamber 101 of the present embodiment gradually increases from the direction away from the bearing cover 204, wherein the buffer casing 10 is provided with a discharge hole 11 at the projection position of the barrier disc 21 toward the buffer casing 10, and the discharge hole 11 is communicated with the buffer chamber 101. When the spiral discharging bearing buffering structure of the embodiment works, the material intruding into the buffering cavity 101 from the assembling gap where the buffer casing 10 and the bearing cover 204 are attached to each other inevitably can flow along the inner wall of the buffer casing 10 towards the discharging hole 11 and is discharged outwards from the discharging hole 11, so that the material is limited to be intruded into the bearing 203 again, of course, the discharging hole 11 is arranged at the projection position of the barrier disc 21 towards the buffer casing 10, and the material outside the buffer casing 10 can be limited to be intruded into the buffering cavity 101 from the discharging hole 11.

Specifically, the inner wall of the buffer casing 10 of the present embodiment is configured as a conical surface so as to facilitate the material to flow along the inner wall of the buffer casing 10 to the position of the discharge hole 11.

The position of the discharge hole 11 on the buffer casing 10 of the present embodiment is adjacent to the cover plate 20, so as to ensure that the material around the buffer casing 10 does not reversely intrude into the buffer cavity 101 through the discharge hole 11.

Further, the number of the discharge holes 11 is plural, and the plural discharge holes 11 are uniformly formed on the buffer casing 10, so that the buffer casing 10 is improved to discharge the material in the buffer cavity 101 to the outside when rotating along with the rotating shaft 201.

In the present embodiment, the thickness of the baffle plate 21 of the present embodiment is gradually reduced from the direction away from the cover plate 20. Thereby improving the blocking effect of the blocking disc 21 on the material and facilitating the material discharged from the discharge hole 11 to be discharged outwards under the guidance of the blocking disc 21.

The damper of the present embodiment is fixed to the rotating shaft 201 by the limit screw 102 penetrating through the damper, thereby realizing the assembling connection of the damper to the rotating shaft 201.

In addition, the number of the dampers of the present embodiment is two, and the two dampers are respectively disposed at both outer sides of the bidirectional helical discharging roller 202, so that the helical discharging bearing damping structure can protect the two bearings 203 from the intrusion of the material.

In summary, the buffer structure of the spiral discharging bearing provided by the invention is provided with the buffer at the position between the bidirectional spiral discharging roller and the bearing to limit the material from entering the bearing from the position of the bidirectional spiral discharging roller, so that the protection of the bearing against the invasion of the material is realized, and the service life of the bearing is further prolonged.
