Abstract
Description
Technical Field
[0001] This application relates to the field of distance adjustment technology, and in particular to a distance adjustment device for a liquid filling machine. Background Technology
[0002] From the perspective of material packaging, filling machines can be categorized into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the perspective of automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines. Liquid filling machines are required for processing and producing care solutions or disinfectants. During filling, different product specifications require different bottle sizes, necessitating different production lines for different product sizes. Furthermore, the impact of filling liquid into the bottle can easily cause it to shake or even tip over, affecting the filling effect and quality.
[0003] Patent document CN220703189U discloses a fully automatic filling machine, including a worktable and filling bottles. A conveying device is located in the center of the worktable, with filling bottles evenly spaced on the conveying device. A mounting frame is fixedly mounted on the worktable, and a lifting component is located at the top of the mounting frame. The lifting component has filling components that match the filling bottles, and the filling components also have a sealing mechanism. A positioning component matching the filling bottles is located on the inner side wall of the mounting frame. Beneficial effects: Before filling, the height of the filling components can be adjusted according to the size of the filling bottles, allowing for optimal filling distance and preventing liquid spillage during filling. This allows it to be adapted to filling products of different specifications. The positioning components clamp and position the side walls of the filling bottles during filling, ensuring stability, preventing shaking or tipping, preventing liquid spillage, avoiding waste, and keeping the worktable clean.
[0004] In the above technical solution, when filling materials, the varying distances between filling bottles cause the clamping devices installed on both sides to be unable to properly clamp the bottles, affecting the output of materials and making it unsuitable for adjusting the spacing of containers of different sizes. Therefore, we propose a fully automatic filling machine to solve this problem. Utility Model Content
[0005] To address the issue that during material filling, the varying distances between filling bottles prevent the clamping devices installed on both sides from effectively holding the bottles, thus affecting material output, this application provides a distance adjustment device for a liquid filling machine.
[0006] The distance adjustment device for a liquid filling machine provided in this application adopts the following technical solution:
[0007] A distance adjustment device for a liquid filling machine includes a frame, a lifting mechanism mounted on the top of the frame, a conveying device mounted on the frame, a material conveying mechanism mounted on the frame, a rotating component mounted on the lifting mechanism, and multiple filling bottles placed on the top of the conveying device. The lifting mechanism includes a first servo motor, which is fixedly connected to the outside of the frame. The output shaft of the first servo motor is driven by a drive shaft via a first coupling. A first connecting block is fixedly connected to the outside of the frame. A bevel gear set, comprising two bevel gears meshing with each other, is mounted on the inner side of the first connecting block. The output end of the drive shaft is fixedly connected to one of the bevel gears, and a threaded rod is fixedly connected to the top of the other bevel gear. The threaded rod is rotatably connected to the inner side of the first connecting block, and a connecting block is threadedly connected to the outer side of the threaded rod.
[0008] Preferably, the rotating assembly includes a second connecting block, which is fixedly connected to the outside of the top cover, and a first circular block is rotatably connected to the inside of the top cover.
[0009] Preferably, a second servo motor is fixedly connected to the outer side of the top cover, and the output shaft of the second servo motor is connected to the inner side of the first circular block through a second coupling.
[0010] Preferably, a plurality of push rods are rotatably connected to the inner side of the first circular block, and the ends of the plurality of push rods away from the first circular block are mounted on the same second circular block, and a plurality of ventilation holes are provided on the outer side of the first circular block.
[0011] Preferably, a connecting plate is fixedly connected to the outer side of the frame, a sliding groove is provided on the connecting plate, a guide rod is fixedly connected to the inner side of the sliding groove, a slider is slidably connected to the outer side of the guide rod, and the slider is rotatably connected to the outer side of the second circular block.
[0012] Preferably, the feeding mechanism includes multiple cylinders, which are fixedly connected to the inner side of the frame. The bottom of the multiple cylinders is equipped with the same lower pressure plate. A feeding pipe is installed on the inner side of the frame, which passes through the frame and the lower pressure plate to feed the material from the outside into the inner side of the filling bottle.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] 1. As the push rod gradually rotates towards its lowest point, the increasingly lower longitudinal distance allows it to directly push the bottles placed below to move laterally. The first circular block rotates at a uniform speed under the influence of the second servo motor, ensuring that the bottles are conveyed at equal intervals. The second servo motor's speed is higher than that of the conveying device, allowing for better adjustment of the distance between multiple bottles. When filling materials, arranging them at specific intervals allows for better control of the filling tubes, thereby improving the device's efficiency.
[0015] 2. When the bevel gears rotate, the meshing of the two bevel gears drives the other gear to rotate, which in turn drives the threaded rod to rotate. When the threaded rod rotates, it drives the second connecting block connected to the outer thread to move upward, thereby adjusting the multiple push rods installed on one side to move up and down. This allows for the adjustment of the position of filling bottles of different heights, adapting to various containers of different specifications, achieving fast and seamless adjustment of the filling head height, and meeting the diverse needs of the production line.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0023] This application discloses a distance adjustment device for a liquid filling machine, referring to... Figure 1-5The device includes a frame 1, characterized in that a lifting mechanism 3 is installed on the top of the frame 1, a conveying device 2 is installed on the frame 1, a material conveying mechanism is provided on the frame 1, a rotating component is provided on the lifting mechanism 3, and multiple filling bottles 4 are placed on the top of the conveying device 2; the lifting mechanism 3 includes a first servo motor 5, which is fixedly connected to the outside of the frame 1, and the output shaft of the first servo motor 5 is driven by a transmission shaft 6 through a first coupling; a first connecting block 7 is fixedly connected to the outside of the frame 1, and a bevel gear set 18 is installed on the inside of the first connecting block 7; the bevel gear set 18 includes two bevel gears that mesh with each other; the output end of the transmission shaft 6 is fixedly connected to one of the bevel gears, and a threaded rod 8 is fixedly connected to the top of the other bevel gear; the threaded rod 8 is rotatably connected to the inside of the first connecting block 7, and a second connecting block 9 is threadedly connected to the outside of the threaded rod 8.
[0024] Reference Figure 1-5 The rotating assembly includes a second connecting block 9, which is fixedly connected to the outside of the top cover 10, and a first circular block 11 is rotatably connected to the inside of the top cover 10.
[0025] Reference Figure 1-5 A second servo motor is fixedly connected to the outer side of the top cover 10, and the output shaft of the second servo motor is connected to the inner side of the first circular block 11 through a second coupling.
[0026] Reference Figure 1-5 Multiple push rods 12 are rotatably connected to the inner side of the first circular block 11. The ends of the multiple push rods 12 away from the first circular block 11 are equipped with the same second circular block 13. Multiple ventilation holes 15 are opened on the outer side of the first circular block 11.
[0027] Reference Figure 1-5 A connecting plate 14 is fixedly connected to the outer side of the frame 1. A sliding groove is provided on the connecting plate 14. A guide rod 16 is fixedly connected to the inner side of the sliding groove. A slider 17 is slidably connected to the outer side of the guide rod 16. The slider 17 is rotatably connected to the outer side of the second circular block 13. The filling bottle 4 is conveyed by the conveying device 2. When the filling bottle 4 enters the lower part of the rotating component, the second servo motor drives the first circular block 11 installed on the inner side of the top cover 10 to rotate, thereby driving the multiple push rods 12 installed on the outer side of the first circular block 11 to rotate. When the push rod 12 gradually rotates to the lowest end, the push rod 12 can directly push the filling bottle 4 placed below to move laterally because the longitudinal distance is getting lower and lower. Because the first circular block 11 rotates at a uniform speed under the rotation of the second servo motor, the filling bottles 4 are conveyed at equal intervals. The speed of the second servo motor is higher than the speed of the conveying device 2, which better adjusts the distance between the multiple filling bottles 4.
[0028] Reference Figure 1-5The material conveying mechanism includes multiple cylinders, which are fixedly connected to the inside of the frame 1. The bottom of the multiple cylinders is equipped with the same lower pressure plate. A material conveying pipe is installed on the inside of the frame 1, which passes through the frame 1 and the lower pressure plate to input the material from the outside into the inside of the filling bottle 4.
[0029] The implementation principle of the distance adjustment device for a liquid filling machine according to this application embodiment is as follows: Both the first servo motor 5 and the second servo motor are electrically connected to an external power supply via a switch. When the operator uses this device, the operator conveys the filling bottles 4 through the conveying device 2. When the filling bottles 4 enter the area below the rotating assembly, the second servo motor is activated via the switch. The second servo motor drives the first circular block 11 installed inside the top cover 10 to rotate, thereby driving multiple push rods 12 installed outside the first circular block 11 to rotate. As the push rods 12 gradually rotate towards the lowest point, the push rods 12, due to their increasingly lower longitudinal distance, can directly push the filling bottles 4 placed below to move laterally. Because the first circular block 11 rotates at a uniform speed under the rotation of the second servo motor, the filling bottles 4 are conveyed at equal intervals. The rotation speed of the second servo motor is higher than the rotation speed of the conveying device 2, thus better adjusting the distance between the multiple filling bottles 4. When filling materials, arranging them at a certain interval allows for better control of the filling tube, thereby improving the efficiency of the device.
[0030] When it is necessary to adjust the spacing of materials of different heights equally, the operator starts the first servo motor 5 by switching on the switch. When the first servo motor 5 rotates, it drives the transmission shaft 6 to rotate through the coupling at one end of the output shaft. When the transmission shaft 6 rotates, it drives the bevel gear at one end to rotate. When the bevel gear rotates, because the two bevel gears mesh with each other, it can drive another gear to rotate, which in turn drives the threaded rod 8 to rotate. When the threaded rod 8 rotates, it drives the second connecting block 9 with the outer thread to move upward, thereby adjusting the multiple push rods 12 installed on one side to move up and down, thus adapting to the position adjustment of filling bottles 4 of different heights.
