[0027] like Figure 1 and Figure 2As shown, in this embodiment, the powder feeding device includes a slide structure 10, a trigger structure 20, a cutter structure 30, and a reset member 40. The slide structure 10 is used to transport bagged items and is provided with an escape opening 11. The trigger structure 20 is swingably disposed within the slide structure 10 and has an initial position and a trigger position. When the bagged items move on the slide structure 10, the trigger structure 20 is driven to move from the initial position to the trigger position. The tool structure 30 includes a tool holder 31 and a cutting blade 32 mounted on the tool holder 31. The tool structure 30 is connected to the bottom of the slide structure 10 and has an avoidance position and a cutting position. When the tool structure 30 is in the avoidance position, the cutting blade 32 is located below the avoidance opening 11. When the tool structure 30 is in the cutting position, the cutting blade 32 extends from the avoidance opening 11 into the slide structure 10. The trigger structure 20 drives and cooperates with the tool structure 30. When the trigger structure 20 moves from the initial position to the trigger position, the tool structure 30 moves from the avoidance position to the cutting position. A reset member 40 is disposed between the tool holder 31 and the slide structure 10 to maintain the tool structure 30 in the avoidance position.

[0028] Using the technical solution of this embodiment, a slide structure 10 is used to transport bagged items. A trigger structure 20 is swingably disposed within the slide structure 10. The trigger structure 20 has an initial position and a trigger position. When the bagged items move on the slide structure 10, the trigger structure 20 can be driven to move from the initial position to the trigger position. A cutter structure 30 includes a cutter holder 31 and a cutting blade 32 disposed on the cutter holder 31.

When the cutter structure 30 is in the clearance position, the cutting blade 32 is located below the clearance opening 11 in the slide structure 10. When the cutter structure 30 is in the cutting position, the cutting blade 32 extends from the clearance opening into the slide structure 10. The trigger structure 20 drives and cooperates with the cutter structure 30. When the trigger structure 20 moves from the initial position to the trigger position, the cutter structure 30 moves from the clearance position to the cutting position. A reset member 40 is disposed between the cutter holder 31 and the slide structure 10 to maintain the cutter structure 30 in the clearance position. Through the above arrangement, the trigger structure 20 and the cutter structure 30 can be linked, so that when the bagged items slide on the slide structure 10, the trigger structure 20 is triggered, and the cutter structure 30 is moved from the avoidance position to the cutting position. After the bagged items pass through the trigger structure 20, the reset member 40 drives the cutter structure 30 back to the avoidance position, so that the cutting knife 32 is hidden under the slide structure 10. This can avoid scratching the operator when cleaning the slide structure 10. Therefore, the technical solution of the present application effectively solves the problem of the cutter being fixed in the slide structure in the related art, which is easy to scratch the operator.

[0029] This design enables the powder feeding device to automatically identify and cut bagged items, improving production line efficiency and safety.

The centerline of the first frame 311 and the centerline of the second frame 312 form a first preset angle. The cutting blade 32 is disposed on the first frame 311, and the reset member 40 is disposed between the second frame 312 and the slide structure 10. The cutting blade 32 is disposed on the first frame 311, which allows the cutting blade 32 to more accurately align with the cutting position of the bagged items, improving cutting accuracy and efficiency. Furthermore, by adjusting the first preset angle, the length by which the cutting blade 32 extends beyond the avoidance opening 11 can be adjusted, ensuring the stability and efficiency of the cutting blade 32 during cutting. The reset member 40 is positioned so as to avoid affecting the cutting blade 32.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the slide structure 10 includes a slide body 12 and a connecting frame 13 arranged below the slide body 12, the first end of the tool holder 31 is hingedly connected to the connecting frame 13, the reset member 40 is arranged between the second end of the connecting frame 13 and the tool holder 31, and the cutting knife 32 is arranged at the first end or the second end of the connecting frame 13. This hinged connection method enables the tool structure 30 to flexibly switch between the avoidance position and the cutting position, reduces the wear of the equipment, extends the service life, and is suitable for continuously running automated production lines. The hinged connection design enables the tool structure 30 to respond quickly to the trigger signal and quickly reset after completing the cutting action, thereby ensuring the continuity of the production line and reducing downtime. This design is particularly suitable for high-speed continuously running automated production lines, such as the milk powder packaging line in a large food processing plant, and can ensure the efficient and stable operation of the production line.

[0032] like Figures 1 to 5As shown, in this embodiment, the knife holder 31 includes a first frame 311 and a second frame 312, and a first preset angle is formed between the center line of the first frame 311 and the center line of the second frame 312. The cutting knife 32 is arranged on the first frame 311, the reset member 40 is arranged between the connecting frame 13 and the second frame 312, and the trigger structure 20 is driven and cooperated with the second frame 312. Such a design makes the drive of the trigger structure 20 more stable and the cutting action smoother, which is suitable for high-production line speed environments that require frequent cutting, such as the automated packaging line of a large food processing plant. This design performs particularly well in high-production line speed environments, can effectively avoid equipment failures caused by frequent cutting, and maintain long-term stable operation of the production line. In addition to the automated packaging lines of large food processing plants, this design is also suitable for various production lines that require frequent automated cutting, thereby improving the automation level and efficiency of the production line.

[0033] like Figures 1 to 5 As shown, in this embodiment, the powder feeding device also includes a transmission member 50, which is arranged between the trigger structure 20 and the second frame 312. The first end of the transmission member 50 is hingedly connected to the trigger structure 20, and the second end of the transmission member 50 is hingedly connected to the second frame 312. The addition of the transmission member 50 makes the linkage between the trigger structure 20 and the tool structure 30 more efficient, reduces energy loss, and is suitable for material processing that requires precise control of cutting force, such as the packaging of fine powdered materials such as milk powder and coffee powder. The design of the transmission member 50 not only improves the coordination of the cutting action, but also can accurately control the cutting force by adjusting its structural parameters, avoiding incomplete cutting or material damage due to excessive or insufficient force. This design is particularly suitable for production lines that process fine powdered materials, such as milk powder, coffee powder, fine chemical raw materials, etc., ensuring the integrity and quality of the material during the cutting process.

[0034] like Figures 1 to 5 As shown, in this embodiment, the trigger structure 20 includes a trigger plate 21 and a connecting rod 22, and a second preset angle is formed between the trigger plate 21 and the connecting rod 22. The trigger plate 21 is located inside the slide structure 10, and the first end of the connecting rod 22 is connected to the trigger plate 21. The second end of the connecting rod 22 is located below the slide structure 10 and is driven by the tool structure 30. This structural design enables the trigger structure 20 to respond more sensitively to the movement of the bagged items, improves the timeliness of cutting, and is suitable for production lines with fast material flow, such as high-speed milk powder packaging lines. The coordinated use of the trigger plate 21 and the connecting rod 22 enables the powder feeding device to accurately capture the movement signal of the bagged items, ensuring the timeliness and accuracy of cutting even on high-speed production lines. Specifically, this design is particularly suitable for high-speed milk powder packaging lines and other material processing production lines that require high efficiency and high precision, and can significantly improve the overall performance of the production line.

[0035] like Figures 1 to 5 As shown, in this embodiment, the slide structure 10 is provided with a mounting slot 14, the length direction of the mounting slot 14 being the same as the extension direction of the slide structure 10, and the connecting rod 22 is disposed within the mounting slot 14. The design of the mounting slot 14 allows for smoother movement of the connecting rod 22 and reduces cutting errors caused by vibration. Specifically, the design of the mounting slot 14 reduces vibration of the connecting rod 22 during the cutting process, thereby improving cutting accuracy. The mounting slot 14 also limits the position of the connecting rod 22, thereby making the position of the connecting rod 22 more stable and ensuring that the bagged items can drive the trigger structure 20.

[0036] like Figures 1 to 5 As shown, in this embodiment, the connecting frame 13 includes a connecting seat 131 and an extension member 132. The connecting seat 131 is disposed below the slide body 12, and the extension member 132 extends toward a side away from the slide body 12. The reset member 40 is disposed between the extension member 132 and the cutter structure 30. The reset member 40 is stably connected to the cutter structure 30, ensuring that the cutting blade 32 is securely stored when not in use, preventing accidental injury and improving the safety of the production environment. This is suitable for production environments where safety is a concern.

[0037] like Figures 1 to 5 As shown, in this embodiment, the powder feeding device further includes a conveyor belt 61 and a collection structure 62. The conveyor belt 61 is located at the first end of the slide structure 10, and the collection structure 62 is located at the second end of the slide structure 10. The slide structure 10 is arranged at an angle. The coordinated use of the conveyor belt 61 and the collection structure 62, as well as the inclined arrangement of the slide structure 10, greatly improves the material conveying speed and collection efficiency, reduces manual intervention, and is suitable for production lines that require efficient processing of large quantities of materials, such as the automated packaging and transportation of powdered materials such as milk powder and flour.

[0038] Specifically, the addition of the conveyor belt 61 and the collection structure 62 makes the material conveying and collection process more automated, reducing labor costs. At the same time, the inclined setting of the slide structure 10 utilizes gravity to further increase the flow rate of materials, significantly improving the processing capacity of the production line. In terms of application scenarios, in addition to production lines for powdered materials such as milk powder and flour, this design is also suitable for various industries requiring efficient material processing, such as chemical raw materials, grain processing, and pharmaceutical manufacturing, and can effectively improve the automation level and processing efficiency of the production line.

[0039] The powder feeding device of this embodiment realizes the function of automatically cutting the bagged items through the linkage between the trigger structure 20 and the tool structure 30, thereby improving the degree of automation of the production line. At the same time, the tool structure 30 is kept in the avoidance position by the reset member 40, avoiding interference in the non-cutting state and ensuring the smooth operation of the production line. In addition, through the inclined setting of the slide structure 10 and the coordination of the conveyor belt 61 and the collection structure 62, the transportation and collection process of the items is further optimized, the production efficiency is improved, the labor cost is reduced, and the overall production environment and safety performance are improved.

By employing the powder dosing device of the present application, the milk powder production line achieves automatic cutting and dosing of bagged milk powder. This not only improves the automation level of the production line and reduces manual operation, but also effectively avoids production errors and safety issues caused by manual operation, significantly improving production efficiency and product quality. Furthermore, the widespread application of this device, such as in the automatic processing of bagged materials in industries such as food, chemicals, and pharmaceuticals, not only reduces production costs but also improves the overall production environment and safety performance, thus possessing extremely high market value and application prospects. In practical applications, the powder dosing device of the milk powder production line can be flexibly adjusted according to the production line speed and material characteristics, ensuring cutting accuracy and powder dosing uniformity, thereby improving the packaging quality of the milk powder and the production line's production capacity. Furthermore, by reducing manual intervention, the risk of cross-contamination during the production process is reduced, and product hygiene standards are improved. In terms of safety, the automatic cutting function of the device prevents operators from directly contacting the cutting tool, reducing safety hazards during the production process.

[0041] Overall, the powder feeding device of this application not only improves the automation level and production efficiency of the milk powder production line, but also effectively ensures production safety and product quality.
