[0041] Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar modifications without violating the connotation of the present invention, so the present invention is not limited to the specific implementation disclosed below.

[0042] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] like Figure 1 and Figure 2 As shown, the present invention provides a rotating rod device for a spray rod container, which includes a conveying mechanism for conveying horizontal containers 8 at intervals, on which a rotating bottle orientation assembly 2, a spray rod flipping mechanism 4 and a pressing rod mechanism 5 are sequentially arranged; the rotating bottle orientation assembly 2 includes a rotating bottle mechanism and a bottle head retaining bar 22, and the rotating bottle mechanism cooperates with the bottle head retaining bar 22 to rotate the container 8 to the same orientation of the spray rod 81; the spray rod flipping mechanism 4 is used to flip the spray rod 81 of the container 8 to the side of the container 8; the pressing rod mechanism 5 is used to flip the spray rod 81 tilted at the side of the container 8 to be parallel to the center line of the container 8.

[0045] In this embodiment, the rotating rod device of the spray rod container realizes the rotation and positioning of the container 8 through the rotating bottle orientation assembly 2 set on the conveying mechanism, so that after the container 8 with the spray rod 81 lies down and enters the conveying mechanism, the bottle body of the container 8 can be rotated to the same direction as the spray rod 81 through the rotating bottle mechanism, and the bottle head blocking bar 22 is set to limit the bottle body of the container 8 to prevent the container 8 from moving during the rotation process. After the bottle body of the container 8 is turned over, the container 8 enters the spray rod turning mechanism 4 station, and the spray rod 81 of the container 8 is turned over by the spray rod turning mechanism 4, so that the spray rod 81 is rotated to the side of the bottle body of the container 8, so that the pressing rod mechanism 5 presses the spray rod 81 into and turns it to be parallel to the center line of the container 8, thereby realizing the automatic positioning and turning of the container with the spray rod. The rotating rod device of the spray rod container realizes the automatic positioning and flipping of the container with the spray rod through the coordinated arrangement of the rotating bottle orientation component 2, the spray rod flipping mechanism 4 and the pressing rod mechanism 5, thereby improving the production efficiency of such containers 8, avoiding the traditional production method in which the container 8 with the spray rod 81 can only be produced by manual rotation, reducing labor costs and improving economy.

[0046] like Figure 3 and Figure 7As shown, the bottle rotating mechanism includes a bottle rotating belt 21 and a rear end limiting rod 6; the bottle rotating belt 21 can abut against the top of the container 8, and the container 8 rotates with the rotation of the bottle rotating belt 21 to adjust the direction of the spray rod 81 on the container 8, and the rear end limiting rod 6 can abut against the bottom end of the bottle body of the container 8, and the rear end limiting rod 6 is set on the conveying mechanism to limit the lateral movement of the container 8.

[0047] In this embodiment, the setting of the bottle rotating belt 21 enables it to be pressed against the bottle body of the container 8 with the spray rod 81. The rotation of the bottle rotating belt 21 drives the rotation of the bottle body of the container 8 so that the bottle body of the container 8 rotates to be consistent with the direction of the spray rod 81, and the setting of the rear end limit rod 6 further limits the movement of the bottle body of the container 8 to avoid movement during the rotation of the bottle body.

[0048] See also Figure 3 , Figure 4 and Figure 8 The spray bar flipping mechanism 4 includes a lifting bar guide bar 41, a straightening guide bar 42 and a pressing bar guide bar 43; the lifting bar guide bar 41, the straightening guide bar 42 and the pressing bar guide bar 43 are arranged in sequence, and the container 8 passes through the lifting bar guide bar 41, the straightening guide bar 42 and the pressing bar guide bar 43 one by one, and the lifting bar guide bar 41, the straightening guide bar 42 and the pressing bar guide bar 43 are all in contact with the spray bar 81 of the container 8, the lifting bar guide bar 41 is used to lift the spray bar 81 of the container 8 so that the spray bar 81 rotates to the side of the container 8, the straightening guide bar 42 is used to straighten the rotated spray bar 81, and the pressing bar guide bar 43 is used to cover the container 8 so that the spray bar 81 rotates to correspond to the pressing bar mechanism 5. And the rotation angle of the spray bar 81 under the action of the lifting bar guide bar 41, the straightening guide bar 42 and the pressing bar guide bar 43 can be ≥120°.

[0049] In this embodiment, the container 8 with the spray rod 81 passes through the lifting rod guide bar 41, the straightening guide bar 42 and the pressing rod guide bar 43 in sequence, wherein the lifting rod guide bar 41 abuts against the end of the spray rod 81 away from the container 8 so that the spray rod 81 rotates to the side of the container 8, the straightening guide bar 42 abuts against the end of the spray rod 81 close to the container 8 to further straighten the spray rod 81 after rotating through the lifting rod guide bar 41, and the pressing rod guide bar 43 presses on the container 8 so that the spray rod 81 rotates to a position corresponding to the pressing rod mechanism 5. Moreover, in this embodiment, the bottom end of the bottle body of the container 8 abuts against the rear end limit rod 6 so that the bottle body of the container 8 runs stably when the spray rod 81 rotates to prevent the bottle body from moving.

[0050] In a preferred embodiment, the spray bar turning mechanism 4 is further provided with a bottle pressing mechanism 3 , which includes a bottle pressing belt 31 , which can abut against the container 8 to prevent the bottle body of the container 8 from rotating.

[0051] like Figure 5 , Figure 6,and Fig. 9 , Fig.10 As shown, the pressure rod mechanism 5 includes a plurality of pressure blocks 51, and the pressure blocks 51 contact the spray rod 81 of the container 8 to flip the spray rod 81 tilted at the side of the container 8 to be parallel to the center line of the container 8.

Therefore, by setting the pressure block 51, the pressure block 51 is abutted against the spray rod 81 to push the spray rod 81 to rotate until the center line of the spray rod 81 is parallel to the center line of the container 8.

[0052] See also Figure 1 and Figure 2 The rotary rod device of the spray rod container includes a thumbwheel unloading mechanism 1, which is used to unload the container 8 so that the container 8 lies flat and enters the rotating bottle orientation assembly 2.

The inner wall of the fence 12 abuts against the container 8 to limit the container 8 from rotating with the unloading thumbwheel 17. The end of the fence 12 is provided with a guide assembly to guide the unloading direction of the container 8. After being guided by the guide assembly, the container 8 is unloaded on the feeding assembly, and the end of the feeding assembly is connected to the rotating bottle orientation assembly 2. The container 8 is unloaded and enters the rotating bottle orientation assembly 2 with the rotation of the unloading thumbwheel 17.

[0053] In addition, its guide assembly includes an upper guide rod 131 and a lower guide rod 132, both of which are arranged on the fence 12, and both of which can abut against the container 8 so that the container 8 can be turned over to the feeding assembly; the feeding assembly includes a feeding plate 14, a supporting plate 15 and a feeding guard plate 16; the feeding plate 14 is arranged below the feeding thumb wheel 17, the supporting plate 15 is arranged on the outer circumference of the feeding plate 14 to limit the position where the container 8 turns over, and the feeding guard plate 16 is arranged at the end of the feeding plate 14 and is connected to the bottle rotation and orientation assembly 2.

[0054] In a preferred embodiment, the rotary rod device further includes a detection mechanism 7, which includes a detection photoelectric, a waste rejection swing rod and a waste rejection box; the detection photoelectric, the waste rejection swing rod and the waste rejection box are all arranged at the end of the conveying mechanism, the waste rejection swing rod is rotatably arranged above the conveying mechanism, and the waste rejection box is arranged on one side of the conveying mechanism to collect the container 8. After the container 8 is flipped by the pressure rod mechanism 5, the photoelectric detection is used to detect whether the spray rod 81 on the side of the container 8 is flipped to be parallel to the center line of the container 8. The container 8 that has not been flipped by the spray rod 81 is transferred to the waste rejection box for collection through the waste rejection swing rod. In this embodiment, the setting of the detection mechanism 7 further improves the automation of the device.
