In addition, the embodiments of the present application can repeatedly refer to numerals and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, which in itself does not indicate the relationship between the various implementations and / or arrangements discussed.

[0035] Referring to Figures 1-2 As shown, the embodiment provides a turning mechanism of a multi-sided container, which comprises a support 1, a transmission star wheel 2 rotatably arranged on the support 1, a plurality of through holes 3 arranged along the circumferential direction of the transmission star wheel 2, a plurality of turning assemblies 4 corresponding to the through holes 3 and arranged on the transmission star wheel 2 in an elastic lifting manner, and a limiting assembly 5 arranged on the support 1. In the embodiment, the cross section of the multi-sided container 8 is rectangular.

[0036] The limiting assembly 5 is located on the transmission path of the multi-sided container 8, and is used for limiting the passing multi-sided container 8, so that the multi-sided container 8 remains relatively stationary with the transmission star wheel 2. By arranging the limiting assembly 5, when the turning assembly 4 turns the multi-sided container 8 by a set angle (in the embodiment, the multi-sided container 8 is turned to be tangent to the motion trajectory at its wide side), the multi-sided container 8 can enter the limiting assembly 5 in the tangent state and remain in the tangent state until it is output from the limiting assembly 5.

[0037] The turning assembly 4 comprises a mounting seat 41 arranged on the transmission star wheel 2 in an elastic lifting manner, a rotating shaft 42 rotatably arranged in the mounting seat 41, a pulley 43 arranged on the upper end of the rotating shaft 42, a connecting piece 44 arranged on the lower end of the rotating shaft 42, and a roller 45 rotatably arranged on the mounting seat 41. The upper and lower ends of the rotating shaft 42 respectively extend out of the mounting seat 41. The rotating shaft 42 and the pulley 43 are coaxially arranged, the connecting piece 44 is used for penetrating the through hole 3 and connecting the multi-sided container 8 when the rotating shaft 42 descends, and is used for disconnecting the multi-sided container 8 when the rotating shaft 42 ascends.

[0038] In the embodiment, the axis of the pulley 43 is parallel to the axial direction of the transmission star wheel 2 and extends in the vertical direction, and the axis of the roller 45 is parallel to the radial direction of the transmission star wheel 2 and extends in the horizontal direction.

[0039] In the embodiment, the connecting piece 44 is an elastic expansion piece used for extending into the multi-sided container 8. When the rotating shaft 42 descends, the connecting piece 44 can enter the multi-sided container 8 and expand after being elastically squeezed, and can drive the multi-sided container 8 to rotate synchronously when the rotating shaft 42 rotates. When the rotating shaft 42 ascends, the connecting piece 44 can be disconnected from the multi-sided container 8 upward after being elastically squeezed.

[0040] The turning assembly 4 further comprises an elastic support 46 arranged between the mounting base 41 and the transmission star wheel 2 along the elastic direction of the elastic support 46, and the elastic support 46 is used to provide an elastic restoring force for the upward movement of the driving roller 45. In the embodiment, the turning assembly 4 further comprises a guide post 47 arranged on the transmission star wheel 2, and the mounting base 41 is provided with a guide hole for the guide post 47 to pass through, and the elastic support 46 is a spring sleeved on the guide post 47. The elastic direction of the spring, the guide post 47 and the guide hole are parallel to each other, and are parallel to the axial direction of the transmission star wheel 2 respectively. The upper end of the guide post 47 is provided with a limit spring, which can prevent the mounting base 41 from being separated upward from the guide post 47.

[0041] The turning assembly 4 further comprises a transmission belt 6 arranged on the support 1 and used to drive the belt wheel 43 to rotate to drive the multi-sided container 8 to rotate synchronously, and a cam 7 arranged on the support 1 and used to press the roller 45 downward. The lower end surface of the cam 7 comprises a descending section 71, a stable section 72 and an ascending section 73 connected in sequence. In the embodiment, the descending section 71 gradually descends along the revolution direction of the roller 45, the stable section 72 is arranged horizontally, and the ascending section 73 gradually ascends along the revolution direction of the roller 45.

[0042] When the transmission star wheel 2 rotates, the turning assembly 4 passes through the transmission belt, and the belt wheel 43 rotates to drive the rotating shaft 42 to rotate synchronously under the drive of the transmission belt 6. In the embodiment, the transmission belt 6 is in the shape of a circular arc, so that the belt wheel 43 can rotate while maintaining revolution. Similarly, the cam 7 is also in the shape of a circular arc, so that the roller 45 can rotate while maintaining revolution.

[0043] When the transmission star wheel 2 rotates, the turning assembly 4 passes through the cam 7, and the roller 45 can roll along the lower end surface of the cam 7 through the outer circumferential part thereof. When the roller 45 rolls on the descending section 71, the mounting base 41 and the rotating shaft 42 move downward synchronously under the drive of the cam 7, and the connecting piece 44 enters the multi-sided container 8 downward; when the roller 45 rolls on the stable section 72, the height of the mounting base 41 and the rotating shaft 42 remains unchanged, and the belt wheel 43 drives the rotating shaft 42 and the multi-sided container 8 to rotate synchronously under the drive of the transmission belt 6; when the roller 45 rolls on the ascending section 73, the mounting base 41 and the rotating shaft 42 move upward synchronously under the action of the elastic support 46, and the connecting piece 44 separates from the multi-sided container 8 upward.

[0044] The cam 7 and the transmission belt 6 are arranged in the radial direction of the transmission star wheel 2, and in the embodiment, the stable section 72 of the cam 7 and the transmission belt 6 are arranged in the radial direction of the transmission star wheel 2. Through this arrangement, it can be ensured that the transmission belt 6 drives the belt wheel 43 to rotate synchronously when the roller 45 rolls on the stable section 72, that is, when the rotating shaft 42 is connected to the multi-sided container 8 through the connecting piece 44, so as to realize the rotational orientation of the multi-sided container 8.

[0045] The conveyor belt 6 and the cam 7 are respectively located at the inlet end of the limiting component 5 so that the multifaceted container 8 after rotation and orientation can directly enter the limiting component 5.

[0046] The aforementioned limiting component 5 includes an outer baffle 51 and an inner baffle 52 arranged radially at intervals along the conveyor star wheel 2 on the support 1 and used to cooperate with each other to abut against the side of the multifaceted container 8. Both the outer baffle 51 and the inner baffle 52 are arc-shaped, wherein the outer baffle 51 is used to abut against the outer side of the bottle body of the multifaceted container 8, and the inner baffle 52 is used to abut against the inner side of the bottle body of the multifaceted container 8. In this embodiment, the limiting component 5 also includes a bottle mouth baffle 53 disposed on the support 1 and used to abut against the outer side of the bottle mouth of the multifaceted container 8.

[0047] The aforementioned conveyor wheel 2 includes a wheel body 21 and a pressure plate 22 covering the wheel body 21. Through holes 3 are formed on the pressure plate 22, and the through holes 3 are aligned vertically with the grooves on the wheel body 21 for engaging the bottle opening. The diameter of the through holes 3 is smaller than the diameter of the bottle opening of the multifaceted container 8. This design prevents the multifaceted container 8 from being lifted upwards when the connector 44 detaches upwards.

[0048] The working process of this embodiment is described in detail below:

[0049] Transmission Star Wheel 2 rotates around its own axis:

[0050] See Figure 3 As shown, at this time, the roller 45 rotates to below the descending section 71 of the cam 7. Driven by the descending section 71, the mounting base 41 and the rotating shaft 42 descend synchronously until the connecting piece 44 extends downward into the mouth of the multifaceted container 8, tightens and connects the multifaceted container 8.

[0051] See Figure 4 As shown, at this time, the roller 45 rotates to the beginning of the smooth section 72 of the cam 7, the height of the mounting base 41 and the rotating shaft 42 remains unchanged, and the pulley 43 rotates under the drive of the conveyor belt 6, driving the multi-faceted container 8 to rotate synchronously.

[0052] See Figure 5 As shown, at this time, the roller 45 rotates to the end of the smooth section 72 of the cam 7, and the multifaceted container 8 rotates to the set orientation, that is, its wide side is tangent to its motion trajectory;

[0053] See Figure 6 As shown, at this time, the roller 45 rotates to below the rising section 73 of the cam 7. Under the action of the elastic support 46, the mounting base 41 and the rotating shaft 42 rise synchronously until the connecting piece 44 exits upward from the bottle mouth of the multifaceted container 8.

[0054] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
