Description

Technical Field

[0001] This utility model relates to the field of preservation device technology, specifically a nitrogen preservation device for beverage filling. Background Technology

[0002] A material filling machine, also known as a filling machine, is a device used to fill liquids, semi-liquids, pastes, powders, and other materials into containers. The filling machine uses a material supply system to transport the material to be filled to the filling section. This material supply system can employ various methods, such as gravity feeding, screw conveyors, or pumps. The appropriate supply method is selected based on the material's properties and filling requirements. The filling machine uses a metering device to control the material's volume according to the set filling requirements, ensuring that the amount of material in each container reaches the preset standard. Metering control can be achieved using different sensors, metering valves, and other devices. After metering control, the material is transported into the filling unit, which then fills the containers. The design of the filling unit can be adjusted according to different material characteristics and filling requirements to ensure the accuracy and efficiency of the filling process.

[0003] In existing technology, before filling beverage cans with beverages, nitrogen is injected into the cans to prevent air inside the cans from affecting the beverages. Then, the beverages are poured into the cans to preserve them. However, existing nitrogen injection equipment requires a period of time after injecting nitrogen into the cans before the beverages are poured in. During this waiting period, some of the nitrogen evaporates, causing some air to enter the cans when the beverages are poured in, which in turn affects the quality of the beverages.

[0004] Therefore, a nitrogen preservation device for beverage filling is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a nitrogen preservation device for beverage filling, so as to solve the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a nitrogen preservation device for beverage filling, including a mounting frame 1, a beverage can body 2 mounted on the mounting frame 1, an adjustment mechanism mounted on the mounting frame 1, the adjustment mechanism being adapted to the beverage can body 2, a liquid injection mechanism, a nitrogen filling mechanism, and a rotation mechanism mounted on the adjustment mechanism, a lifting mechanism mounted on the mounting frame 1, the lifting mechanism being mounted on the adjustment mechanism, the adjustment mechanism including two movable plates 3, two limiting grooves 312 formed on the mounting frame 1, the two movable plates 3 being slidably mounted on the inner walls of the two limiting grooves 312, both movable plates 3 being slidably mounted on the mounting frame 1, a rotating shaft 31 being rotatably mounted on the two movable plates 3, a beverage filling head 32 and a nitrogen filling head 33 being mounted on the rotating shaft 31. A beverage storage tank 34 is installed on the mounting frame 1. A pump 35 is installed on the beverage storage tank 34. A connecting pipe 36 is installed on the pump 35. One end of the connecting pipe 36 is installed on the beverage filling head 32. A nitrogen generator 38 is installed on the mounting frame 1. A connecting pipe 39 is provided on the nitrogen generator 38. The other end of the connecting pipe 39 is installed on the nitrogen filling head 33. The beverage filling head 32 and the nitrogen filling head 33 are distributed at 90 degrees. The rotating shaft 31 drives the beverage filling head 32 and the nitrogen filling head 33 to rotate, so that the beverage filling head 32 and the nitrogen filling head 33 can be conveniently moved to the top of the beverage can body 2 for use in sequence. Thus, the beverage can body 2 can be filled with nitrogen for preservation and beverage filling in the same position in sequence.

[0026] Furthermore, a first solenoid valve 37 is installed on the connecting pipe 36, a second solenoid valve 310 is installed on the connecting pipe 39, and a PLC control device 311 is installed on the mounting bracket 1. The PLC control device 311 is connected to the first solenoid valve 37 and the second solenoid valve 310 via electrical cables. With the PLC control device 311, after the beverage filling head 32 and the nitrogen filling head 33 are rotated to be directly above the beverage can body 2, the corresponding second solenoid valve 310 and the first solenoid valve 37 can be automatically controlled to open, thereby realizing the filling of nitrogen and beverage. At the same time, the PLC control device 311 is a programmable logic controller. It uses a type of programmable memory to store programs internally, execute user-oriented instructions such as logical operations, sequential control, timing, counting and arithmetic operations, and control various types of machinery or production processes through digital or analog input / output. In essence, it is a computer dedicated to industrial control. Its hardware structure is basically the same as that of a microcomputer. It is generally used for data processing and instruction reception and output to realize central control.

[0027] Furthermore, the drive mechanism includes a support plate 4, which is mounted on one of the movable plates 3. A first motor 41 is mounted on the support plate 4, and a rotating shaft 42 is mounted on the first motor 41. The rotating shaft 42 is mounted on a rotating shaft 31. A fixing block 43 is mounted on one of the movable plates 3, and a positioning hole 44 is provided on the fixing block 43. A limit shaft 45 is mounted on one end of the rotating shaft 31. The limit shaft 45 is rotatably mounted on the inner wall of the positioning hole 44. The first motor 41 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives the rotating shaft 31 to rotate. This allows the beverage filling head 32 and the nitrogen filling head 33 on the rotating shaft 31 to be rotated sequentially to the top of the beverage can body 2 for use. At the same time, the positioning hole 44 and the limit shaft 45 effectively limit the rotation position of the rotating shaft 31.

[0028] Example 2: Based on Example 1, in order to facilitate the movement of the beverage filling head 32 and nitrogen filling head 33 on the rotating shaft 31 into the beverage can body 2 for filling, a lifting mechanism is arranged on the mounting frame 1. Specifically, it includes a second motor 5, which is mounted on the mounting frame 1. A drive shaft 51 is mounted on the second motor 5, a transmission plate 52 is mounted on the drive shaft 51, a movable shaft 53 is mounted on the transmission plate 52, and a transition plate 54 is slidably mounted on the movable shaft 53. Two retaining rods 55 are mounted on the bottom side of the transition plate 54, and the two retaining rods 55 are distributed on the two movable plates 3. The adapter plate 54 has a strip hole 56. The movable shaft 53 is slidably installed on the inner wall of the strip hole 56. The second motor 5 drives the drive shaft 51 to rotate. The drive shaft 51 drives the transmission plate 52 to rotate. The transmission plate 52 drives the movable shaft 53 to rotate. The movable shaft 53 drives the adapter plate 54 to move downward. The adapter plate 54 drives the retaining rod 55 to move downward. The retaining rod 55 drives the nitrogen filling head 33 or the beverage filling head 32 on the rotating shaft 31 to move downward to the inside of the beverage can body 2, so as to facilitate the filling of nitrogen or beverage into the inside of the beverage can body 2. The remaining features are the same as in Embodiment 1.

[0029] The working principle is as follows: Before filling the beverage can body 2 with beverage, nitrogen is first injected into the beverage can body 2 using a nitrogen filling head 33 for preservation. After the beverage can body 2 is placed on the mounting bracket 1, the first motor 41 drives the rotating shaft 42 to rotate, which in turn drives the rotating shaft 31 on the movable plate 3 to rotate. The rotating shaft 31 aligns the nitrogen filling head 33 with the bottom of the beverage can body 2. Then, the switch on the second motor 5 is activated, which drives the drive shaft 51 to rotate. The drive shaft 51 drives the transmission plate 52 to rotate, which in turn drives the movable shaft 53 to rotate. The movable shaft 53 moves the adapter plate 54 downward, which in turn moves the retaining rod 55 downward. The retaining rod 55 moves the nitrogen filling head 33 on the rotating shaft 31 downward to the inside of the beverage can body 2. Then, using P... The LC control device 311 opens the switch on the second solenoid valve 310, allowing nitrogen generated by the nitrogen generator 38 to be conveniently injected into the beverage can body 2 through the nitrogen filling head 33 for preservation. After injecting nitrogen into the beverage can body 2, the second motor 5 drives the rotating shaft 31 to move upward, removing the nitrogen filling head 33 from the beverage can body 2. Simultaneously, the first motor 41 drives the rotating shaft 42 to rotate, which in turn drives the rotating shaft 31 to rotate counterclockwise, thus conveniently rotating the beverage filling head 32 to the normal position of the beverage can body 2. Then, the second motor 5 moves the beverage filling head 32 downward into the beverage can body 2, allowing the beverage in the beverage storage tank 34 to be conveniently injected into the beverage can body 2 through the beverage filling head 32.
