Description

Technical Field

[0001] This application relates to the field of filling machine technology, and in particular to a synchronous drive structure for a filling machine. Background Technology

[0002] As an important piece of equipment in the packaging industry, filling machines are mainly used in the packaging of food, pharmaceuticals, cosmetics and chemicals.

[0003] To ensure production efficiency, multiple liquid storage bottles are usually filled simultaneously. The liquid in the storage tank is delivered into the storage bottle through a nozzle. During operation, it is necessary to ensure that the filling volume of each bottle is the same. Since each storage bottle is filled using a separate inlet pipe, each storage bottle is independent of the others, making it difficult to control the filling volume of each storage bottle to be the same, which is an area for improvement. Utility Model Content

[0004] In order to ensure that the filling volume of each liquid storage bottle is the same, this application provides a synchronous drive structure for a filling machine.

[0005] This application provides a synchronous drive structure for a filling machine, which adopts the following technical solution:

[0006] A synchronous drive structure for a filling machine includes a filling frame and a protective frame. The filling frame is disposed inside the protective frame. A plurality of filling units are disposed on the filling frame. Each filling unit includes a connecting pipe for connecting to a liquid storage tank and a push rod for piston movement inside the connecting pipe. The filling frame is also provided with a drive structure for synchronously driving the push rod to perform piston operation and a fixing frame for fixing the connecting pipe. One end of the push rod is connected to the connecting pipe, and the other end of the push rod is connected to the drive structure.

[0007] By adopting the above technical solution, one end of the push rod is connected to the connecting pipe and the other end is connected to the drive structure. When each connecting pipe is filled with liquid, the drive structure can simultaneously push all the push rods to perform piston movement in the corresponding connecting pipe, so that the output of each filling unit is consistent, thereby achieving efficient and synchronous filling operation, which helps to improve filling efficiency and filling quality.

[0008] Preferably, the drive structure includes a lifting plate, a lead screw, and a drive motor for driving the lead screw to rotate. A threaded sleeve for forming a threaded engagement with the lead screw is rotatably connected to the lifting plate. One end of the lead screw is rotatably connected to the filling frame, and the other end of the lead screw is connected to the output shaft of the drive motor. The end of the push rod away from the connecting pipe is connected to the lifting plate.

[0009] By adopting the above technical solution, the drive motor drives the lead screw to rotate, and the lead screw drives the threaded sleeve to rise and fall. At this time, the threaded sleeve drives the lifting plate to rise and fall, so that the lifting plate can synchronously drive all the push rods to perform piston movement in the corresponding connecting pipes, thereby controlling the liquid output in each connecting pipe to remain the same.

[0010] Preferably, the filling frame is provided with a guide rod for guiding the push rod to move up and down stably. Several guide rods are provided, and any one of the guide rods forms a guide sliding cooperation with the lifting plate.

[0011] By adopting the above technical solution and utilizing the guide rod, the guide rod can guide the push rod to rise and fall stably, preventing the push rod from deviating or shaking during the rising and falling process, thereby further improving the accuracy and stability of the filling process.

[0012] Preferably, the fixing frame includes a fixing block, a rotating block, and a locking assembly for locking the rotating block onto the rotating block, wherein the fixing block and the rotating block form a rotatable connection, and the fixing block is fixedly mounted on the filling frame body.

[0013] By adopting the above technical solution, a rotating connection is formed by the fixed block and the rotating block, which allows the operator to rotate the rotating block relative to the fixed block, facilitating subsequent maintenance and replacement of the connecting pipes.

[0014] Preferably, the locking assembly includes a first connecting plate, a second connecting plate, and a locking bolt. The first connecting plate is disposed on the rotating block, the second connecting plate is disposed on the fixed block, and the locking bolt passes through the first connecting plate and the second connecting plate in sequence and is threadedly locked.

[0015] By adopting the above technical solution, the first connecting plate and the second connecting plate are connected and fixed by tightening the locking bolts, thereby fixing the rotating block on the fixed block. Then, the fixed block and the rotating block together limit the position of the connecting pipe, reducing the possibility of the connecting pipe shifting during the filling process. At the same time, this design makes it easier for workers to disassemble or repair the connecting pipe.

[0016] Preferably, the rotating block is detachably provided with a limiting plate to facilitate maintenance and replacement of the connecting pipes by the staff. The limiting plate is set according to the position and number of the connecting pipes, and any one of the limiting plates is slidably set on the rotating block and fixed by bolts.

[0017] By adopting the above technical solution and utilizing the setting of the limiting plate, the limiting plate facilitates the maintenance or replacement of the connecting pipe by the staff. The staff can quickly locate and solve the problem of the connecting pipe to be maintained, reducing the maintenance difficulty. At the same time, the setting of the limiting plate also ensures the stability of the connecting pipe during the operation.

[0018] Preferably, any of the limiting plates is provided with a handle that facilitates the worker to pull out the limiting plate.

[0019] By adopting the above technical solution and utilizing the handle, the operator can pull out a single limit plate, thereby accurately operating the connecting pipe that needs to be disassembled and repaired, improving the convenience and efficiency of the operation.

[0020] Preferably, the connecting pipe is equipped with a three-way directional valve for controlling the inflow and outflow of liquid.

[0021] By adopting the above technical solution and utilizing the three-way directional valve, the three-way directional valve can conveniently control the inflow and outflow of liquid, thus achieving precise control of the filling process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. One end of the push rod is connected to the connecting pipe, and the other end is connected to the drive structure. When each connecting pipe is filled with liquid, the drive structure can simultaneously push all the push rods to perform piston movement in the corresponding connecting pipe, so that the output of each filling unit is consistent, thereby achieving efficient and synchronous filling operation, which helps to improve filling efficiency and filling quality.

[0024] 2. By using a fixed block and a rotating block to form a rotating connection, the operator can rotate the rotating block relative to the fixed block, which facilitates subsequent maintenance and replacement of the connected pipes;

[0025] 3. The use of the limit plate facilitates the maintenance or replacement of the connecting pipes by the staff. The staff can quickly locate the connecting pipe to be repaired and solve the problem, reducing the difficulty of maintenance. At the same time, the limit plate also ensures the stability of the connecting pipes during operation. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0030] This application discloses a synchronous drive structure for a filling machine.

[0031] Reference Figure 1 A synchronous drive structure for a filling machine includes a filling frame 1 and a protective frame 2. The filling frame 1 is disposed inside the protective frame 2. In this embodiment, guide rails 21 are symmetrically welded inside the protective frame 2. The two ends of the filling frame 1 are respectively slidably disposed on the guide rails 21, and the operator uses bolts to abut and limit the filling frame 1 to the guide rails 21. This design facilitates the installation and disassembly of the filling frame 1 by the operator. The protective frame 2 provides a physical barrier for the entire filling frame 1 and the filling unit 11 on it, preventing the filling unit 11 from being affected by external interference and thus affecting the filling operation.

[0032] Reference Figure 1 A filling unit 11 is provided on the filling frame 1. There are multiple filling units 11. In this embodiment, there are six filling units 11. Since the structure and connection method of the six filling units 11 are the same, we will now describe one of the filling units 11 as an example.

[0033] Reference Figure 1 The filling unit 11 includes a connecting pipe 111 for connecting to the liquid storage tank and a push rod 112 for piston movement inside the connecting pipe 111. A connecting rod 22 is welded and fixed on the protective frame 2. A clamping ring 221 is threadedly connected to the connecting rod 22 corresponding to the position and number of the connecting pipe 111. Any clamping ring 221 is used to clamp and fix the corresponding connecting pipe 111, thereby reducing the possibility of the connecting pipe 111 shaking during the filling process.

[0034] Reference Figure 1The filling frame 1 is also provided with a drive structure 12 for synchronously driving the push rod 112 to perform piston operation and a fixing frame 13 for fixing the connecting pipe 111. The push rod 112 passes through the filling frame 1 and the fixing frame 13, and one end of the push rod 112 is connected to the connecting pipe 111, and the other end of the push rod 112 is connected to the drive structure 12.

[0035] Reference Figure 1 By fixing the connecting pipe 111 with the fixing bracket 13, the damage to the connecting pipe 111 caused by liquid impact is reduced, thereby enhancing the stability and reliability of the overall structure. When each connecting pipe 111 is filled with liquid, the drive structure 12 can simultaneously push all push rods 112 to perform piston movement in the corresponding connecting pipe 111, so that the output of each filling unit 11 is consistent, thereby achieving efficient and synchronous filling operation, which helps to improve filling efficiency and filling quality.

[0036] Reference Figure 1 The drive structure 12 includes a lifting plate 121, a lead screw 122, and a drive motor 123 for driving the lead screw 122 to rotate. The drive motor 123 is mounted on the protective frame 2 and is located below the filling frame 1. A threaded sleeve 1211 is rotatably connected to the lifting plate 121 and is fitted inside the lifting plate 121. The threaded sleeve 1211 and the lead screw 122 form a threaded engagement. One end of the lead screw 122 is rotatably connected to the filling frame 1 and is fitted inside the filling frame 1. The other end of the lead screw 122 is coaxially connected to the output shaft of the drive motor 123. In this embodiment, one end of the push rod 112 is slidably connected inside the connecting pipe 111, and the other end of the push rod 112 is threadedly connected to the lifting plate 121.

[0037] Reference Figure 1 In use, the operator operates the drive motor 123 to drive the lead screw 122 to rotate. The lead screw 122 drives the threaded sleeve 1211 to rise and fall. At this time, the threaded sleeve 1211 drives the lifting plate 121 to rise and fall. Thus, the lifting plate 121 can synchronously drive all push rods 112 to perform piston movement in the corresponding connecting pipes 111, thereby controlling the liquid output in each connecting pipe 111 to keep it the same.

[0038] Reference Figure 1The filling frame 1 is provided with guide rods 14. There are multiple guide rods 14. In this embodiment, there are six guide rods 14. Any guide rod is vertically installed inside the filling frame 1. Any guide rod 14 forms a guide sliding fit with the lifting plate 121. Both ends of any guide rod are threadedly connected to the filling frame 1. By using the guide rods 14, the guide rods 14 can guide the push rod 112 and the lifting plate 121 to move up and down stably, preventing the push rod 112 from deviating or shaking during the lifting process, and further improving the accuracy and stability of the filling process.

[0039] Reference Figure 1 and Figure 2 The fixing frame 13 includes a fixing block 131, a rotating block 132, and a locking assembly 133 for locking the rotating block 132 onto the rotating block 132. The fixing block 131 is fixedly mounted on the filling frame 1. In this embodiment, the fixing block 131 is bolted to the filling frame 1. The fixing block 131 and the rotating block 132 form a rotatable connection, that is, the rotating block 132 rotates relative to the fixing block 131, which facilitates subsequent maintenance and replacement of the connecting pipe 111.

[0040] Reference Figure 1 and Figure 2 The locking assembly 133 includes a first connecting plate 1331, a second connecting plate 1332, and a locking bolt 1333. The first connecting plate 1331 is integrally formed on the rotating block 132, and the second connecting plate 1332 is integrally formed on the fixed block 131. The bolt shank of the locking bolt 1333 passes through the first connecting plate 1331 and the second connecting plate 1332 in sequence and is locked by the nut thread.

[0041] Reference Figure 1 and Figure 2 Workers connect and fix the first connecting plate 1331 and the second connecting plate 1332 by tightening the locking bolts 1333, thereby stably connecting the rotating block 132 to the fixed block 131. The fixed block 131 and the rotating block 132 together limit the position of the connecting pipe 111, reducing the possibility of the connecting pipe 111 shifting position during the filling process. At the same time, workers can disassemble or repair the connecting pipe 111 by rotating and opening the fixed block 131.

[0042] Reference Figure 1 and Figure 2 A limit plate 1321 is detachably provided on the rotating block 132. The position and number of the limit plate 1321 are set according to the connection pipe 111. A sliding groove 1322 is set on the rotating block 132 according to the position and number of the limit plate 1321. Any limit plate 1321 forms a sliding fit with the corresponding sliding groove 1322, and any limit plate 1321 is connected to the rotating block 132 by bolt thread.

[0043] Reference Figure 1 and Figure 2 When a problem occurs in one of the connecting pipes 111, the staff can quickly locate and resolve the issue. By unscrewing the bolts on the corresponding limiting plate 1321 and removing the limiting plate 1321, the staff can disassemble, repair, or replace the connecting pipe 111, reducing maintenance difficulty. At the same time, the setting of the limiting plate 1321 also ensures the stability of the connecting pipe 111 during the filling process.

[0044] Reference Figure 1 and Figure 2 The rotating block 132 is provided with a first half-ring 1323 corresponding to the position and number of the connecting pipe 111, and the fixed block 131 is provided with a second half-ring 1311 corresponding to the position and number of the connecting pipe 111. The inner rings of the first half-ring 1323 and the second half-ring 1311 are both in abutting fit with the connecting pipe 111. Any first half-ring 1323 is bolted to the limiting plate 1321, and any second half-ring 1311 is bolted to the fixed block 131. Thus, the first half-ring 1323 and the second half-ring 1311 together stably limit the position of the connecting pipe 111, further improving the stability of the connecting pipe 111 during the filling process.

[0045] Reference Figure 2 A handle 13211 is welded onto any of the limit plates 1321. The handle 13211 allows the operator to pull out a single limit plate 1321, thereby accurately operating the connecting pipe 111 that needs to be disassembled and repaired, improving the convenience and efficiency of the operation.

[0046] Reference Figure 1 A three-way reversing valve 1111 is installed on the connecting pipe 111. One side of the three-way reversing valve 1111 is connected to the liquid storage tank, one side is connected to the connecting pipe 111, and one side is connected to the liquid storage bottle. The three-way reversing valve 1111 can conveniently control the inflow and outflow of liquid, realizing precise control of the filling process.

[0047] The implementation principle of this application embodiment is as follows: In actual use, the operator closes the side of the three-way reversing valve 1111 that is connected to the liquid storage bottle, so that the connecting pipe 111 is connected to the liquid storage tank. When each connecting pipe 111 is filled with liquid, the operator closes the side of the three-way reversing valve 1111 that is connected to the liquid storage tank, so that the connecting pipe 111 is connected to the liquid storage bottle. Then, the operator operates the drive motor 123 to drive the lead screw 122 to rotate. The lead screw 122 drives the threaded sleeve 1211 to rise and fall. At this time, the threaded sleeve 1211 drives the lifting plate 121 to rise and fall. Thus, the lifting plate 121 can synchronously drive all the push rods 112 to perform piston movement in the corresponding connecting pipe 111, thereby controlling the liquid output in each connecting pipe 111 to remain the same.

[0048] The fixed block 131 and the rotating block 132 together limit the position of the connecting pipe 111. When the staff needs to install or remove six connecting pipes 111, they can directly install or remove the connecting pipes 111 by turning the locking bolt 1333 to separate the fixed block 131 and the rotating block 132. When the staff needs to install or remove one or more connecting pipes 111, they can quickly locate and solve the problem of the connecting pipe 111 to be repaired. The staff can remove the connecting pipe 111 by turning the bolt on the corresponding limiting plate 1321 and removing the limiting plate 1321, thereby reducing the difficulty of maintenance.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
