[0036] See also Figures 1 to 7 As shown, this preferred embodiment provides an aluminum bottle mouth grooving machine, which includes a workbench 1, a rotating mechanism 2, a grooving mechanism 3 and a lifting mechanism 4.

[0037] Among them, the workbench 1 is provided with a loading station 11, a unloading station 12 and several processing stations 13 arranged in a ring. The loading station 11 is connected to the loading line, and the unloading station 12 is connected to the unloading line. Each processing station 13 is used to complete the grooving process in steps.

[0038] In this embodiment, there is one loading station 11 and one unloading station 12, and four processing stations 13 are provided. The four processing stations 13 are used to complete the grooving processing respectively, thereby facilitating the formation of more complex groove shapes.

[0039] The rotating mechanism 2 includes a turntable 21 rotatably arranged on the workbench 1, which is specifically driven to rotate by a third motor 23 on the lower surface of the workbench 1. A plurality of guide grooves 22 (here 6) evenly distributed in a circle are provided on the turntable 21 corresponding to the loading station 11, the unloading station 12, and the processing station 13. The turntable 21 rotates to a set angle (here 60°) so that the aluminum bottle workpiece 6 embedded in the guide groove 22 passes through the loading station 11, the four processing stations 13, and the unloading station 12 one by one.

[0040] In particular, the loading line and the unloading line are integrated into an annular assembly line 5, the turntable 21 is placed in the annular assembly line 5, and several bottom molds 51 for placing workpieces 6 are arranged in the annular assembly line 5. The surface of the guide groove 22 is adapted to the surface of the bottom mold 51, thereby improving the circulation efficiency of the workpiece 6 and reducing the volume of the equipment.

[0041] The groove rolling mechanism 3 is located above the workbench 1 and includes an inner mold 31 and a disc wheel 32. The inner mold 31 and the disc wheel 32 cooperate to clamp and act on the wall of the workpiece 6. Given the presence of multiple processing stations 13, the inner mold 31 and the disc wheel 32 of the front and rear processing stations 13 are correspondingly adapted and gradually approach the target groove shape.

[0042] Among them, a first bracket 14 is provided on the workbench 1 and directly above the turntable 21, and a central fixed block 15 is provided on the first bracket 14. An inner mold fixed block 16 is provided on the central fixed block 15 corresponding to each processing station 13. The inner mold 31 is passed through the inner mold fixed block 16 through a bearing, and a disc wheel fixed block 17 is provided on the outer side of the inner mold fixed block 16. The disc wheel 32 is passed through the disc wheel fixed block 17 through a bearing. By adjusting the gap between the inner mold fixed block 16 and the disc wheel fixed block 17, the distance between the inner mold 31 and the disc wheel 32 is changed.

[0043] Specifically, a spring is sandwiched between the inner mold fixing block 16 and the disc wheel fixing block 17, and a first gear plate 33 is provided on the periphery of each disc wheel fixing block 17. An inclined top block 34 is provided on the inner ring of the first gear plate 33 to support the disc wheel fixing block 17. A first motor 35 is provided on the first bracket 14, and a first gear is provided at the output end of the first motor 35. The first gear is engaged with the outside of the first gear plate 33, thereby driving the first gear plate 33 to rotate, and then driving the disc wheel fixing block 17 to approach or move away from the inner mold fixing block 16 to provide the required clamping force and facilitate loading and unloading.

[0044] A second bracket 18 is provided on the first bracket 14, and a second motor 36 is provided on the second bracket 18. The second motor 36 is connected to a second gear plate 37. A second gear is provided on the rotating shaft of each inner mold 31, and a third gear is provided on the rotating shaft of each disc wheel 32. The second gear plate 37 is sequentially connected to the second gear and the third gear, thereby driving each inner mold 31 and the disc wheel 32 to rotate at the same time to meet the rolling groove action requirements.

[0045] It is worth mentioning that, since the inner mold 31 and the disc wheel 32 move relative to each other, in order to ensure that the rotating shafts of the two can transmit normally, an articulated arm is provided in the rotating shaft to compensate for the displacement.

[0046] In particular, an angular travel rod 38 is provided on the output shaft of the first motor 35 and the second motor 36 respectively, and a first proximity switch 39 is provided on one side of the angular travel rod 38 to facilitate monitoring the rotation of the first gear plate 33 and the second gear plate 37.

[0047] The lifting mechanism 4 is located below the workbench 1 and is used to lift the workpiece 6 in the processing station 13 and send it between the inner mold 31 and the disc wheel 32 to facilitate grooving. It includes a lifting cylinder 41 fixed to the lower surface of the workbench 1, preferably a servo electric cylinder. The output end of the lifting cylinder 41 is provided with a lifting rod 42, which passes through the bottom mold 51 and acts on the workpiece 6.

[0048] In addition, a second proximity switch 19 is provided at the loading station 11 and the unloading station 12 respectively, so as to check the loading and unloading conditions and shut down the machine in time when an abnormality occurs.

[0049] In this regard, the process steps based on the above-mentioned aluminum bottle mouth groove rolling machine are as follows:

[0050] Step S100: The aluminum bottle workpiece 6 is sequentially placed in the bottom mold 51 on the feeding side of the circular assembly line 5, transported forward and inserted into the guide groove 22 as the turntable 21 rotates, and arrives at the feeding station 11;

[0051] Step S200: The turntable 21 rotates 60° and then automatically locks. The workpiece 6 is transferred from the loading station 11 to the first processing station 13. The ejector pin 42 of the corresponding station is actuated to lift the workpiece 6 between the inner mold 31 and the disc wheel 32 of the corresponding station. The inner mold 31 and the disc wheel 32 clamp both sides of the bottle wall of the workpiece 6 to perform the first step of grooving. After the grooving is completed, the inner mold 31, the disc wheel 32, and the ejector pin 42 of the first processing station 13 are reset.

[0052] Step S300: The turntable 21 rotates 60° and then automatically locks. The workpiece 6 is transferred from the first processing station 13 to the second processing station 13. The ejector pin 42 of the corresponding processing station is actuated to lift the workpiece 6 between the inner mold 31 and the disc wheel 32 of the corresponding processing station. The inner mold 31 and the disc wheel 32 clamp both sides of the bottle wall of the workpiece 6 to proceed to the second step of grooving. After the grooving is completed, the inner mold 31, the disc wheel 32, and the ejector pin 42 of the second processing station 13 are reset.

[0053] Step S400: The turntable 21 rotates 60° and then automatically locks. The workpiece 6 is transferred from the second processing station 13 to the third processing station 13. The ejector pin 42 of the corresponding processing station is actuated to lift the workpiece 6 between the inner mold 31 and the disc wheel 32 of the corresponding processing station. The inner mold 31 and the disc wheel 32 clamp both sides of the bottle wall of the workpiece 6 to proceed to the third step of grooving. After the grooving is completed, the inner mold 31, the disc wheel 32, and the ejector pin 42 of the third processing station 13 are reset.

[0054] Step S500: The turntable 21 is automatically locked after rotating 60°, and the workpiece 6 is transferred from the third processing station 13 to the fourth processing station 13, where only three steps of grooving are required, and the workpiece can be left vacant;

[0055] Step S600 : After the turntable 21 rotates 60°, the workpiece 6 is transferred from the fourth processing station 13 to the unloading station 12 . As the turntable 21 rotates, the workpiece 6 returns to the unloading side of the circular assembly line 5 .

[0056] Therefore, the aluminum bottle mouth groove rolling machine has the following advantages:

[0057] 1) Higher production efficiency, with an estimated production rate of 50 pieces per minute;

[0058] 2) Less potential safety hazard and safer production;

[0059] 3) Precise movements and higher product quality;

[0060] 4) Step-by-step processing can produce more complex grooving effects.

[0061] The above embodiments merely illustrate the basic principles and features of the present invention and are not intended to be limiting. Various modifications and variations may be made to the present invention without departing from the spirit and scope of the present invention. Such modifications and variations are intended to fall within the scope of the present invention.
