DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] like Figure 1-5 As shown, a turntable 100 in one embodiment of the utility model includes a frame, a driving assembly and a bearing assembly. The frame includes a machine foot 11 and a mounting plate 12 supported on the machine foot 11. The driving assembly includes a first power source 21 fixed to the frame, and a rotating shaft 22 connected to the first power source 21 and extending above the mounting plate 12. The bearing assembly includes a turntable base plate 31 disposed above the mounting plate 12 and fixed to the rotating shaft 22, and a plurality of rollers 32 fixed to the bottom of the turntable base plate 31, and the rollers 32 are supported on the mounting plate 12. The first power source 21 drives the rotating shaft 22 and the turntable base plate 31 to rotate, and the rollers 32 disposed on the turntable base plate 31 can support the turntable base plate 31 from the periphery to prevent the turntable base plate 31 from tilting after long-term use.

[0028] Traditional turntables usually rely on the central shaft to support the upper turntable, and all the weight on the upper side is concentrated on the shaft. If the center position of the upper support is not on the axis of the turntable, the shaft and the turntable may tilt after long-term use, resulting in the need for maintenance. The turntable 100 in the present application is provided with multiple rollers 32 on the turntable bottom plate 31 to provide multiple support points for the turntable bottom plate 31, reduce the load on the shaft 22, prevent the tilting in the later stage, and ensure the long-term stable operation of the equipment.

[0029] Preferably, the plurality of rollers 32 are on the same circumference with the rotating shaft 22 as the center. Further, the rollers 32 are arranged equidistantly from each other, so that the rollers 32 are evenly distributed around the rotating shaft 22, so that the force on the entire turntable bottom plate 31 is more uniform, and the tilting is further prevented.

[0030] like Figure 1 As shown, the bearing assembly further includes a plurality of rollers 33 supported on the turntable bottom plate 31 , which are driven to rotate by a second power source 23 installed on the turntable bottom plate 31 to perform an object conveying action.

[0031] The first power source 21 and the second power source 23 may be motors or other power devices, which is not limited in this embodiment.

[0032] Specifically, the bearing assembly also includes two support plates 34 that are arranged opposite to each other and fixed on the turntable bottom plate 31. The two ends of the roller 33 are supported on one of the support plates 34, and the second power source 23 is installed on one of the support plates 34. A double gear is provided at one end of the roller 33, and the adjacent double gears are connected by a chain, and the second power source 23 is connected to two (or one) of the double gears, thereby driving all the rollers 34 to rotate. A guide wheel 35 is provided on the top of the support plate 34, which is distributed along the transmission direction of the roller 33 and is used to provide guidance for the transmission of the article to prevent the article from hitting the support plates 34 on both sides and causing scratches or even damage.

[0033] like Figure 1 and 4 As shown, an adapter plate 36 is fixed on the support plate 34, and a guide wheel mounting plate 37 is fixed on the adapter plate 36. The guide wheel mounting plate 37 is a long strip plate extending along the transmission direction of the roller 33, and the guide wheel 35 is mounted on the guide wheel mounting plate 37. In addition, a guide groove 371 parallel to the roller 33 (i.e., perpendicular to the transmission direction of the roller 33) is provided on the guide wheel mounting plate 37, and the fixing screws for fixing the guide wheel mounting plate 37 and the adapter plate 36 pass through the guide groove 371, so that the guide wheel mounting plate 37 can move in the direction perpendicular to the transmission of the article, and the moving range is determined by the length of the guide groove 371, so as to adjust the total width of the article transmission channel, and the flexibility is high.

[0034] In one embodiment, the supporting assembly also includes a collecting plate 38 disposed between the roller 33 and the turntable bottom plate 31, with its two ends fixed to the support plates 34 on both sides to collect waste particles dropped during the transmission of objects, etc., to prevent the waste particles from falling on the turntable bottom plate 31 and affecting the operation of the rotating shaft 22, so as to improve the stability of the turntable 100 during operation.

[0035] Preferably, the bearing assembly further comprises a baffle 39 fixed on the turntable bottom plate 31 and arranged on the outer side of the roller 33 along the transmission direction of the roller 33 to provide a barrier for the transmitted articles to prevent them from falling off the roller 33 during rotation.

[0036] Furthermore, a flexible buffer pad 391 is provided on the baffle 39 and faces the roller 33 to provide a buffer for the transported items to prevent the items from being bumped or damaged by directly hitting the baffle 39 .

[0037] In one embodiment, the turntable 100 is also provided with a buffer mechanism, including a buffer 41 installed on the mounting plate 12, and a buffer plate 42 fixed on the turntable bottom plate 42. When the first power source 21 drives the turntable bottom plate 31 to rotate to a certain angle, the buffer 41 contacts the buffer plate 42 to prevent the turntable bottom plate 31 from continuing to rotate. The first power source 21 reverses after sensing the obstruction, driving the turntable bottom plate 31 to rotate in another direction.

[0038] In one embodiment, the buffer 41 is a buffer pin fixed on the mounting plate 12. When the buffer plate 42 contacts and squeezes the buffer pin, it can continue to move a certain distance, and the buffer pin can provide a continuously increasing resistance. Therefore, the buffer pin and the buffer plate 42 can cooperate to provide a flexible buffer, which can effectively prevent damage to the equipment or power source compared to a hard block, thereby ensuring that the state 100 runs stably for a long time.

[0039] It is easy to imagine that two buffers 41 are provided on the mounting plate 12 to limit the rotation angle of the turntable bottom plate 42 from both sides. The installation positions of the two buffers 41 can be set according to the actual required rotation angle, which is not limited in this embodiment.

[0040] In one embodiment, the driving assembly further includes a bearing seat 24 fixed to the mounting plate 12, the rotating shaft 22 is supported by the bearing seat 24, and is connected to the output shaft of the first power source 21 through a coupling 25. Therefore, when the first power source 21 or the bearing seat 24 fails, the coupling 25 can be removed to release the connection between the rotating shaft 22 and the first power source 21, and then the rotating shaft 22 can be disassembled for maintenance or replacement.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
