Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to a multi-tank compatible filling machine. Background Technology

[0002] On existing liquid filling production lines, meeting the production needs of different bottle types, capacities, and packaging specifications usually requires changing the filling line or switching to specialized equipment. For example, in the beverage production sector, large and small bottle products often use different filling machine structures and conveyor cycles, resulting in low equipment utilization, long changeover times, and poor production flexibility. Especially when different bottle types, such as full-size and trial sizes, exist on the same production line, directly using the same filling nozzle can cause problems such as liquid splashing, unstable flow, and decreased accuracy due to the mismatch between the bottle mouth diameter and the outlet size. To accommodate different bottle types, some factories build additional dedicated small bottle production lines, but this approach not only incurs high investment costs and occupies a large amount of factory space, but also increases the complexity of daily maintenance and management.

[0003] In existing technologies, some equipment attempts to control the filling flow rate of different bottle types by changing the discharge pipe, adjusting the opening of the filling valve, or using throttling devices. However, these machines are mostly designed with a single material channel, making it impossible to flexibly switch between multiple material tanks. Furthermore, switching operating modes in existing filling machines often requires manual disassembly and reassembly of pipes and adjustment of filling valves, a cumbersome process that can easily lead to material waste and cross-contamination. In addition, when multiple materials are produced on the same line, the lack of effective valve-controlled diversion and buffering structures can easily result in material mixing, excessive pressure fluctuations, and unstable filling accuracy, affecting product quality. Therefore, how to achieve multi-tank compatibility, adaptability to different bottle capacities, and stable filling flow rate and accuracy on a single machine is a problem that needs to be solved.

[0004] In view of the above, this application proposes a multi-can compatible filling machine to solve the above problems. Through electronically controlled filling valves combined with buffer, telescopic and diversion structures, it can flexibly switch between large and small bottle filling modes, reduce production line changeover time, improve equipment utilization, and reduce construction and maintenance costs.

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-tank compatible filling machine, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-tank compatible filling machine includes a conveyor line and a connecting rod. The connecting rod is installed on the side of the conveyor line via a connector. The connecting rod is connected to a material tank via the conveyor. A buffer is provided at the top of the connecting rod. A telescopic member is provided at the top of the buffer.

Detailed Implementation

[0029] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] In the description of this utility model, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] This application proposes a multi-tank compatible filling machine, as detailed below:

[0032] For reference Figure 1 The system consists of a conveyor line 1 and a connecting rod 2. The connecting rod 2 is mounted on the side of the conveyor line 1 via a connector 3. The connecting rod 2 is connected to a material tank 4 via a conveyor. A buffer 5 is connected to the top of the connecting rod 2. A telescopic component 6 is provided on the top of the buffer 5. A first connecting shaft 7 is provided at the end of the telescopic component 6 away from the buffer 5. A detachable discharge pipe 8 is provided at one end of the first connecting shaft 7. Through the cooperation of the above structures, daily filling operations can be achieved.

[0033] For reference Figure 1 The conveyor line 1 is used to transport the filling bottles. In one embodiment, the conveyor line transports in groups, and each group contains filling bottles of different sizes. If trial bottles are received by the output port of the standard bottle, it will cause a certain degree of impact. In order to avoid opening another production line, further optimization has been carried out to enable multiple filling situations to be realized when connecting a material tank 4, so that they can work in a compatible manner.

[0034] For reference Figure 1 The connecting rod 2 is fixedly installed on the side of the conveyor line 1 by the connecting piece 3. The connecting rod 2 is connected to the material tank 4 by the conveyor, and the material in the material tank 4 is transported to the connecting rod 2 by the conveyor. It should be noted that the conveyor is a mature existing technology, and this application will not elaborate on it further.

[0035] Furthermore, a third filling valve 21 is provided on the connecting rod 2. The third filling valve 21 controls the material to enter the subsequent connecting structure from the connecting rod 2 and achieves the effect of flowing out from the discharge pipe 8.

[0036] For reference Figure 1-2 To prevent excessive pressure during the conveying process of the connecting rod 2 from causing material to splash out of the filling bottle during output, a buffer 5 is further installed at one end of the connecting rod 2. The buffer 5 includes an outer frame 51 and a threaded channel 52. Both ends of the outer frame 51 are detachably installed between the telescopic part 6 and the connecting rod 2 by screws. The threaded channel 52 is located in the inner cavity of the outer frame 51, so that the liquid in the outer frame 51 flows in a rotating manner. The detachable design facilitates subsequent maintenance and cleaning, reduces problems such as the accumulation of dirt in the pipeline, and the threaded channel 52 reduces the buffer pressure when the material flows, making the output relatively stable.

[0037] For reference Figure 1 and Figure 3During production, changes may occur in the volume and height of the filling bottles. To address these changes, a telescopic component 6 is incorporated. This component includes a first fixed shaft 61, a telescopic shaft 62, a second fixed shaft 63, and a connecting screw 64. The first fixed shaft 61 is detachably connected to the top of the outer frame 51, and the second fixed shaft 63 is detachably connected to the top of the first connecting shaft 7. The telescopic shaft 62 is positioned between the first and second fixed shafts 61 and 63. Each of the first and second fixed shafts 61 and 63 has a connecting plate 65 extending outwards at one end, with the connecting screw 64 passing through both connecting plates 65. This structure allows for adjustment based on different usage scenarios by stretching the telescopic shaft 62 to a suitable height and then fixing it to the two connecting plates 65 using the connecting screw 64. It is worth noting that the telescopic shaft 62 is a folded plastic tube, which is inexpensive and reduces subsequent maintenance costs. Furthermore, the length of the connecting screw 64 is not limited; it can be adjusted to better suit the desired connection length.

[0038] For reference Figure 1 The material in the connecting rod 2 passes through the buffer 5 and the telescopic component 6, enters the first connecting shaft 7, and then flows through the first connecting shaft 7 to the discharge pipe 8, flowing out into the bottle to complete the filling process, whether it is a standard or large bottle. It should be noted that the discharge pipe 8 and the first connecting shaft 7 are detachable, partly for easy cleaning and partly for subsequent adjustments and replacements to a more suitable structure.

[0039] For reference Figure 1 and Figure 3 When it is necessary to fill small bottles, the filling structure of the large port may not be suitable. However, the cost of setting up a separate conveyor and the required equipment for the small bottle filling mechanism is too high. Therefore, a temporary filling component 11 and a connecting pipe 9 are further set up.

[0040] Furthermore, multiple connecting rods 2 are provided, and a connecting pipe 9 is provided between two adjacent connecting rods 2. The connecting pipe 9 is used to branch the liquid flowing inside the connecting rod 2. A first filling valve 10 is provided at one end of the connecting pipe 9. The first filling valve 10 is used to control the connection between two adjacent connecting rods 2. When the first filling valve 10 is open, the two adjacent connecting rods 2 are connected. This is suitable for connecting to a tank for conveying. When working with the tank 4 through one connecting rod 2, one end of the other connecting rod 2 can be blocked by a component. Two sets of temporary filling components 11 are connected to the connecting pipe 9. When the first filling valve 10 is closed, the two temporary filling components 11 are connected to the one of the two adjacent connecting rods 2 that is far away from the first filling valve 10. When the two sets of temporary filling components 11 are working, the third filling valve 21 is closed. At this time, the second filling valve 115 on the two sets of temporary filling components 11 is opened, which can realize the filling requirements of different situations on a single conveyor line.

[0041] The temporary filling assembly 11 includes a three-way pipe 111, a water outlet pipe 112, a second connecting shaft 113, and an extension pipe 114. The three-way pipe 111 is connected to the connecting pipe 9 to achieve three-way connection. The water outlet pipe 112 is connected to the three-way pipe 111 and is equipped with a second filling valve 115, which is used to control the flow of materials. The two ends of the second connecting shaft 113 are connected between the water outlet pipe 112 and the extension pipe 114 by screws. The inner cavity of the second connecting shaft 113 is consistent with the inner cavity of the buffer 5, and is also used to achieve buffering and pressure reduction.

[0042] It should be noted that the first filling valve 10, the second filling valve 115 and the third filling valve 21 are all electronic filling valves. These valves, in conjunction with flow meters or time control modules, achieve filling accuracy for each filling operation. This is a common and mature technology in the prior art, and this application will not elaborate further on it.

[0043] In this invention, the working steps of the device are as follows:

[0044] 1. First, based on the number of connected material tanks 4, one or more connecting rods 2 are connected by a conveyor for use. When not using vial filling, the second filling valve 115 is closed. When working by connecting one connecting rod 2, the first filling valve 10 can be opened to achieve the connection effect between adjacent connecting rods 2.

[0045] 2. Next, the material liquid is conveyed through the conveyor to the connecting rod 2 and flows out through the discharge pipe 8 to complete the filling work;

[0046] 3. Then, if multiple material tanks 4 are connected, and the materials contained in the material tanks 4 are different, the first filling valve 10 is closed, and they do not come into contact with each other, so that the different materials are conveyed for operation (at this time, the second filling valve 115 is closed).

[0047] 4. Finally, when working with a small flow of material, close the third flow valve 21. At this time, the second filling valve 115 can be opened to allow the material to enter the extension pipe 114 for filling. When the filling machine is working, it can achieve compatible operation of multiple filling situations without conflict between them.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
