Description

Technical Field

[0001] The utility model relates to a filling machine, in particular to a synchronous lifting device for a filling needle. Background Art

[0002] The filling needles of the disc filling machine are arranged in a circular array and are equally divided into multiple groups, and each group of filling needles works independently.

[0003] When the product changes, the height of the filling needle needs to be adjusted. The existing filling needle mainly uses a screw and nut structure to fix the height of the filling needle. Therefore, to adjust the height of the filling needle, it is necessary to loosen the nut, then raise and lower the height of the filling needle to the required position as needed, and tighten the nut again.

[0004] Since each group of filling needles is independent, the height of each group of filling needles needs to be adjusted separately. After adjusting one group of filling needles, the disc assembly needs to be rotated to rotate the next group of filling needles to the maintenance station. Therefore, each adjustment of the height of the filling needles takes a long time. If the filling effect is not good, the height of the filling needles needs to be adjusted repeatedly, resulting in an overall long adjustment time and inconvenient adjustment. Utility Model Content

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, a synchronous lifting device for filling needles includes a guide post 2, a lifting plate 3, an active lifting device 4, a driven lifting device 5, a linkage device 6, and a drive device 7. The guide posts 2 are circular rods, with two guide posts 2 forming a group. Five groups of guide posts 2 are provided, and the five groups of guide posts 2 are mounted in a circular array on the filling frame 1. Five lifting plates 3 are provided, and the five lifting plates 3 are arranged in a circular array. The lifting plates 3 are slidably mounted on the guide posts 2, and each lifting plate 3 is evenly connected to two guide posts 2 to prevent the lifting plate 3 from rotating around the guide posts 2, so that the lifting plate 3 can only be lifted in the vertical direction. Each lifting plate 3 is equipped with four filling needles 81, and the filling needles 81 are equipped with filling valves 33. There is one active device 4 and four driven lifting devices 5. The active lifting device 4 and the driven lifting device 5 are both installed on the filling frame 1 and connected by a linkage device 6. The linkage device 6 enables the driven lifting device 5 to rise and fall synchronously with the active lifting device 4; the driving device 7 is connected to the active lifting device 4, and the driving device 7 is used to drive the active lifting device 4 to rise and fall; the active lifting device 4 and the driven lifting device 5 are respectively connected to the lifting plate 3, and are used to drive all the lifting plates 3 and the filling needles 81 to rise and fall.

[0023] The driving device 7 drives the active lifting device 4 to move up and down, and the active lifting device 4 drives the driven lifting device 5 to move up and down through the linkage device 6. The active lifting device 4 and the driven lifting device 5 drive the lifting plate 3 to move up and down synchronously, thereby realizing the synchronous lifting and lowering of all the filling needles 81. There is no need to adjust each group of filling needles 81 separately, which greatly improves the efficiency of height adjustment of the filling needles 81, shortens the adjustment time, and makes the adjustment of the height of the filling needles 81 simpler and more convenient.

[0024] To facilitate height adjustment and improve height adjustment accuracy, the active lifting device 4 includes an active fixing plate 41, an active screw 42, and an active nut 43. The active fixing plate 41 is mounted on the guide column 2, and the end of the active screw 42 is rotatably mounted on the active fixing plate 41 via a bearing seat. The top of the active screw 42 is also connected to the drive device 7. The active nut 43 is mounted on the active screw 42 and is connected to one of the lifting plates 3. The driven lifting device 5 includes a driven fixing plate 51, a driven screw 52, and a driven nut 53. The driven fixing plate 51 is fixed to the guide column 2. The top of the driven screw 52 is rotatably mounted on the driven fixing plate 51 via a bearing seat. The driven nut 53 is mounted on the driven screw 52 and is also connected to the remaining lifting plates 3. The ball screw has high precision and low friction, making adjustment easy and labor-saving.

[0025] To achieve synchronous rotation of the active screw 42 and the driven screw 52, the linkage device 6 includes a driving synchronous pulley 61, a driven synchronous pulley 62, and a linkage synchronous belt 63. There is one active synchronous pulley 61, which is mounted on the active screw 42; there are four driven synchronous pulleys 62, which are respectively mounted on the four driven screws 52; and the linkage synchronous belt 63 is sleeved on the active synchronous pulley 61 and the driven synchronous pulley 62. The synchronous belt and synchronous pulleys can ensure the synchronous rotation of the active screw 42 and the driven screw 52, thereby ensuring synchronous lifting.

[0026] In order to prevent the linkage synchronous belt 63 from slipping against the driving synchronous pulley 61 or the driven synchronous pulley 62, the linkage device 6 also includes a tensioning device 64. The tensioning device 64 is provided on the guide column 2 and movably abuts against the linkage synchronous belt 63 to tighten the linkage synchronous belt 63. Specifically, the tensioning device 64 includes a tensioning rod 641 and a tensioning pulley 642. One end of the tensioning rod 641 is fixed to the guide column 2, and the other end of the tensioning rod 641 is equipped with a tensioning pulley 642. The outer circumference of the tensioning pulley 642 movably abuts against the outer surface of the linkage synchronous belt 63. The tensioning pulley 642 tensions the linkage synchronous belt 63, effectively preventing the linkage synchronous belt 63 from slipping on the synchronous pulleys and improving the reliability of the linkage lifting and lowering adjustment.

[0027] The drive device 7 includes a drive seat 71, a drive assembly, a driving bevel gear 74, and a driven bevel gear 75. The drive seat 71 is fixed to the active fixed plate 41 and connected to the drive assembly. The drive assembly is connected to the driving bevel gear 74, which meshes with the driven bevel gear 75. The driven bevel gear 75 is mounted on top of the active screw 42. The drive assembly drives the active screw 42 via the active bevel gear 74 and the driven bevel gear 75, thereby rotating the active nut 43, which in turn drives the lifting plate 3 up and down. To simplify the structure of the drive assembly, the drive assembly includes a drive shaft 73 and a handwheel 72. The drive shaft 73 is rotatably mounted on the drive seat 71 via a bearing seat. The ends of the drive shaft 73 are respectively connected to the handwheel 72 and the driving bevel gear 74. The handwheel 72 facilitates manual adjustment of the height of the filling needle 81. The handwheel 72 can also be replaced with a motor to achieve automatic adjustment.

[0028] like Figure 4 As shown, to facilitate the installation of the filling needle 81, the lifting plate 3 includes a lifting base plate 31 and a pressing plate 32. The lifting base plate 31 is provided with two lifting holes 312, which are slidably mounted on the guide column 2. The end of the lifting base plate 31 is provided with four first fixing grooves 311 in a circular array. The first fixing grooves 311 are semicircular grooves. The pressing plate 32 is fixed to the end of the lifting base plate 31 by screws. The pressing plates 32 are symmetrically provided with two second fixing grooves 322. The second fixing grooves 322 are semicircular grooves that match the first fixing grooves 311 and are arranged opposite to each other. The second fixing grooves 322 are used to fix the filling needle 81 in the first fixing grooves 311. The pressing plate 32 facilitates the disassembly and assembly of the filling needle 81.

[0029] During operation, the handwheel 72 is rotated according to the needs of filling. The handwheel 72 drives the driven bevel gear 75 to rotate through the active bevel gear 74. The driven bevel gear 75 drives the active screw rod 42 to rotate. The active screw rod 42 drives the active nut 43 to rotate. The active nut 43 drives the lifting plate 3 to rise and fall. When the active screw rod 42 rotates, the active synchronous pulley 61 installed on the active screw rod 42 rotates synchronously. The active synchronous pulley 61 drives the driven synchronous pulley 62 to rotate through the linkage synchronous belt 63. The driven synchronous pulley 62 drives the driven screw rod 52 to rotate. The driven screw rod 52 drives the driven nut 53 to rotate. The driven nut 53 drives the remaining lifting plates 3 to rise and fall. All the lifting plates 3 rise and fall synchronously.
