Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a powder packaging equipment. Background Technology

[0002] When packaging powder, packaging machines are often used to package the powder in a quantitative manner. However, after the packaging machine belt is sealed in the heat-melt sealing structure, it is directly conveyed to the cutting structure for cutting or dicing. The heat-sealed part of the packaging bag is directly cut in a high-temperature molten state, which can easily lead to uneven cut surfaces and incomplete cutting. At the same time, the softened packaging material is also prone to sticking to the cutting parts, causing stringing or deformation defects, which ultimately affect the integrity and appearance quality of the powder packaging. Utility Model Content

[0014] Example 1, as Figure 1-5As shown, this utility model proposes a powder packaging device, including a frame 1, a quantitative feeding structure 2, a vacuum feeding structure 3, a hot-melt sealing structure 4, a cooling structure 5, and a cutting structure 6. The quantitative feeding structure 2 is adjustablely installed on the top of the frame 1 via a lifting mechanism. In use, it holds and stirs the powder, and discharges the powder through a high-precision screw within the quantitative feeding structure 2. The quantity is calculated based on the screw rotation, ensuring the accuracy of each feeding. The stirring and screw components in the quantitative feeding structure 2 are existing technologies and are not shown in the figure. The vacuum feeding structure... The material feeding structure 3 is installed at the inlet of the quantitative feeding structure 2, allowing the vacuum feeding structure 3 to draw powder from the storage tank into the quantitative feeding structure 2 through negative pressure, achieving automatic feeding without manual feeding, thus improving production efficiency and safety. The hot-melt sealing structure 4 is installed on the side of the frame 1 and below the discharge port of the quantitative feeding structure 2. It is used to seal the packaging bags at high temperature during use, sealing the strip-shaped packaging bags to create a cavity for holding the powder. The cutting structure 6 is located below the hot-melt sealing structure 4 and is used to cut the packaging bags sealed by the hot-melt sealing structure 4 during use. Cutting separates the packaging bag into multiple cavities containing powder, or it cuts the area between two powder cavities at the high-temperature sealing point, making the packaging bag a single piece after processing, while still allowing for rapid separation between the two powder cavities. A cooling structure 5 is arranged between the hot-melt sealing structure 4 and the cutting structure 6. During use, the cooling structure 5 can supply gas to the high-temperature sealed packaging bag to rapidly cool it and prevent material deformation. The cooling structure 5 includes a mounting frame 51, an exhaust shell 52, and a transmission assembly. The mounting frame 51 is installed... On the side of the frame 1 and below the hot melt sealing structure 4, there are two exhaust shells 52. The two exhaust shells 52 are symmetrically and rotatably mounted on the inner side of the mounting frame 51. One end of the two exhaust shells 52 and one end of the mounting frame 51 is provided with a conveying component that is rotatably connected to the exhaust shell 52 and conveys gas to the inside of the exhaust shell 52 in the use state. The transmission component is provided at the other end of the mounting frame 51 and connected to the other end of the two exhaust shells 52. The side of the transmission component is provided with a limiting component that is connected to the mounting frame 51 and limits the transmission component in the use state.

[0015] In an optional embodiment, an air outlet 513 is provided on the side of the exhaust housing 52. The air outlet 513 is formed in a strip shape. In use, the air outlet 513 can also be composed of multiple equally spaced circular holes. The length of the air outlet 513 is greater than or equal to the processing length of the hot melt sealing structure 4. It is used to transport the gas inside the exhaust housing 52 to the packaging bag through the air outlet 513 during use.

[0016] In this embodiment, by relaxing the constraint of the limiting component on the transmission component, the exhaust shell 52 can rotate on the mounting frame 51, thereby adjusting the orientation of the exhaust shell 52. Under the action of the transmission component, the two exhaust shells 52 achieve synchronous adjustment. Since the two exhaust shells 52 are symmetrically installed inside the mounting frame 51, their orientations are kept opposite, avoiding the packaging bag from shifting due to gas delivery to different positions of the packaging bag. After the adjustment is completed, the limiting component constrains the transmission component again, so that the exhaust shell 52 is fixed in the mounting frame 51. At the same time, the vacuum feeding structure 3 uses negative pressure to suck the powder from the storage tank into the quantitative feeding structure 2. The quantitative feeding structure 2 is responsible for holding and stirring the powder. Then, the powder is quantitatively discharged through the internal screw, completing the quantitative filling of the strip packaging bag. After filling, the packaging bag moves downward and passes through the heat-sealing structure 4, cooling structure 5 and cutting structure 6 in sequence. During this process, the heat-sealing structure 4 performs intermittent heat sealing on the strip packaging bag to form a sealed cavity for containing the powder. When the packaging bag moves towards the cutting structure 6, the conveying component is activated to generate gas and simultaneously send the gas into the inside of the two exhaust shells 52, so that it blows cooling airflow to both sides of the heat-sealing area of ​​the heat-sealing structure 4 on the packaging bag to achieve rapid cooling, thereby avoiding the problem of stringing or incomplete cutting when the packaging bag moves to the cutting structure 6 for processing.

[0017] Example 2, as Figure 4 As shown, the powder packaging equipment proposed in this utility model differs from Embodiment 1 in that the conveying assembly includes a rotary joint 53, a three-way joint 54, an air pipe 55, and an air pump 56. There are two rotary joints 53, each connected to an exhaust housing 52. The three-way joint 54 is located in the middle of the two rotary joints 53. There are three air pipes 55, with two of them connected to one end of the three-way joint 54 and one rotary joint 53, respectively. The other air pipe is connected to the other end of the mounting frame 51. The air pump 56 is connected to the end of the air pipe 55. The air pump 56 can also be a nitrogen storage tank with an electrically controlled valve, so that the exhaust housing 52 can deliver nitrogen to cool the packaging bag.

[0018] In this embodiment, the ends of the three air pipes 55 are respectively connected to one port of the three-way connector 54, and the other ends of two of the three air pipes 55 are respectively rotatably connected to the exhaust shell 52 through the rotary connector 53. One of the air pipes 55 is connected to the air pump 56, so that the air pump 56 starts to generate gas and delivers the gas synchronously to the two exhaust shells 52 through the cooperation of the three-way connector 54 and the air pipes 55. This allows the two exhaust shells 52 to synchronously deliver the gas to the packaging bag for cooling. At the same time, the exhaust shell 52 is connected to the air pipes 55 through the rotary connector 53, so that when the exhaust shell 52 rotates, it can avoid the exhaust shell 52 driving the rotary connector 53 to rotate, which would cause the air pipes 55 to twist.

[0019] Example 3, as Figure 4-5 As shown, the powder packaging equipment proposed in this utility model differs from Embodiment 1 in that the transmission component includes a gear transmission structure 510 and a synchronous belt transmission structure 511. The synchronous belt transmission structure 511 is located at the other end of the mounting frame 51, with one end connected to an exhaust housing 52 and the other end rotatably mounted on the mounting frame 51. The synchronous belt transmission structure 511 consists of two synchronous pulleys and a synchronous toothed belt. One of the synchronous pulleys is mounted at the end of the exhaust housing 52, and the other synchronous pulley is rotatably connected to the mounting frame 51 via a rotating shaft. The two synchronous pulleys are connected as a single unit by the synchronous toothed belt. The gear transmission structure 510 is located at one end of the synchronous belt transmission structure 511, with one end connected to another exhaust housing 52 and the other end connected to the synchronous belt transmission structure 511. The gear transmission structure 510 consists of two gear assemblies. The two gears are respectively connected to the rotating shafts of the exhaust housing 52 and the synchronous pulleys of the synchronous belt transmission structure 511, and mesh with each other, so that the gears and the synchronous pulleys rotate synchronously.

[0020] In an optional embodiment, a knob 512 is provided at the end of the exhaust shell 52 and on the side of the synchronous belt drive structure 511. The outer surface of the knob 512 is provided with anti-slip texture. When in use, the exhaust shell 52 is driven to rotate by the knob 512, so that the gear drive structure 510 and the synchronous belt drive structure 511 cooperate to make the two exhaust shells 52 rotate relative to each other and synchronously. This makes the adjustment of the exhaust shells 52 more convenient and ensures that the two exhaust shells 52 are aligned, thus preventing the packaging bag from shifting during transportation.

[0021] In this embodiment, by linking the gear transmission structure 510 and the synchronous belt transmission structure 511 at the other end of the mounting frame 51, and connecting one end of the gear transmission structure 510 and the synchronous belt transmission structure 511 to the exhaust shell 52 respectively, when one exhaust shell 52 is connected, the gear transmission structure 510 and the synchronous belt transmission structure 511 cooperate to drive the other exhaust shell 52 to rotate synchronously, so that the two exhaust shells 52 can be adjusted in orientation synchronously, thereby improving the exhaust angle of the exhaust shell 52 and thus improving the cooling effect of the packaging bag.

[0022] Example 4, as Figure 4-5 As shown, the present invention proposes a powder packaging device. Compared with the first embodiment, the difference in this embodiment is that the limiting component includes a connecting seat 57, a toothed disc 58 and a limiting rod 59. The connecting seat 57 is installed at the other end of the mounting frame 51. The toothed disc 58 is rotatably installed on the outside of the connecting seat 57 and meshes with the gear transmission structure 510. The limiting rod 59 is installed at the end of the connecting seat 57 and connected to the toothed disc 58.

[0023] In an optional embodiment, the end of the connecting seat 57 is provided with a threaded joint 516, and one end of the limiting rod 59 is provided with an internal thread groove 515. When the limiting rod 59 and the connecting seat 57 are installed together, the threaded joint 516 is fitted and accommodated in the internal thread groove 515. This is used to quickly install the limiting rod 59 on the connecting seat 57 during use, and to allow the limiting rod 59 to move toward the gear plate 58 through the engagement of the internal thread groove 515 and the threaded joint 516, thereby pressing and fixing the gear plate 58.

[0024] In an optional embodiment, a gasket 514 connected to the limiting rod 59 is provided at the end of the connecting seat 57 and on the side of the gear disk 58. The gasket 514 is made of soft material or metal material, such as a rubber gasket or a metal flat spring gasket. When the limiting rod 59 moves toward the gear disk 58 through the internal thread groove 515 and the threaded joint 516, the limiting rod 59 drives the gasket 514 to press and fix the gear disk 58 onto the connecting seat 57, so that the gear disk 58 is more firmly fixed.

[0025] In this embodiment, by rotatably mounting the gear disc 58 on the connecting seat 57 and meshing with the gear transmission structure 510, the gear disc 58 is driven to rotate synchronously through the gear transmission structure 510 when the exhaust shell 52 rotates. The gear disc 58 is pressed and fixed on the connecting seat 57 by the limiting rod 59, so that the gear disc 58 is fixed between the connecting seat 57 and the limiting rod 59, and the gear disc 58 limits the operation of the gear transmission structure 510. This allows the gear transmission structure 510 and the synchronous belt transmission structure 511 to cooperate in limiting the rotation of the two exhaust shells 52, thus preventing the exhaust shells 52 from rotating during use.

[0026] In this invention, the limiting rod 59 is rotated on the connecting seat 57, causing it to move away from the gear plate 58 through the engagement of the internal thread groove 515 and the threaded joint 516. This loosens the constraint of the limiting rod 59 on the gear plate 58, and drives the exhaust shell 52 to rotate via the knob 512. Simultaneously, the gear transmission structure 510 and the synchronous belt transmission structure 511 are linked at the other end of the mounting frame 51, causing the gear transmission structure 510 and the synchronous belt transmission structure 511 to drive the other exhaust shell 52 to rotate. This allows the two exhaust shells 52 to adjust their orientation synchronously. The two exhaust shells 52 are symmetrically installed on the inner side of the mounting frame 51, ensuring that their orientation angles are the same. Meanwhile, the vacuum feeding structure 3 uses negative pressure to draw powder from the storage tank into the quantitative feeding structure 2. 2 is responsible for holding and stirring the powder, and then discharging the powder quantitatively through the internal screw, completing the quantitative filling of the strip packaging bag. After filling, the packaging bag moves downward and passes through the heat-sealing structure 4, the cooling structure 5 and the cutting structure 6 in sequence. During this process, the heat-sealing structure 4 performs intermittent heat sealing on the strip packaging bag to form a sealed cavity for containing the powder. When the packaging bag moves to the cutting structure 6, the air pump 56 is started to generate gas, and the gas is synchronously delivered to the two exhaust shells 52 through the cooperation of the three-way connector 54 and the air pipe 55. This allows the two exhaust shells 52 to blow cooling airflow onto the heat-sealing area of ​​the heat-sealing structure 4 on one side of the packaging bag through the air outlet 513, achieving rapid cooling and thus avoiding the problem of stringing or incomplete cutting when the packaging bag moves to the cutting structure 6 for processing.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
