Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0027] like Figures 1-10As shown, the present invention provides an automatic bagging machine, including a frame 1, a main drive unit 2 fixedly mounted on the frame 1, and a packaging device 4 fixedly mounted on the frame 1 via a main beam plate 3. The packaging device 4 includes a translation linkage group 5, a bag-picking support plate 6, and a bag-opening device 7. The main drive unit 2 drives and connects to the translation linkage group 5 via a main connecting rod 8. The translation linkage group 5 is fixedly mounted with the bag-picking support plate 6 and the bag-opening device 7. A bag-delivery device 9 is fixedly mounted on the frame 1, including a fixing frame 10, a bag-blowing device 11, and a bearing plate 12. A feeding conveyor 13 and a discharging conveyor belt 14 are fixedly mounted on the frame 1. A blocking support rod 15 is fixedly mounted on the frame 1 above the bag-picking support plate 6, and an adjusting cylinder 16 is fixedly mounted on the blocking support rod 15. The bag-opening device 7 includes an adjusting lever 17, a bag-opening plate 18, and a first drive motor 19. The first drive motor 19 is driven and connected to the first end of the adjusting lever 17 via a lead screw 20, and the other end of the adjusting lever 17 is fixedly mounted with the first drive motor 19. A fixed frame 10 is equipped with an exchange slide 21, which is driven and connected to a support plate 12 via a lifting cylinder 22. Two lifting cylinders 22 are fixedly installed on the exchange slide 21, and each lifting cylinder 22 drives and connects to a support plate 12. A bag sorting device 23 is fixedly installed on the frame 1. The bag sorting device 23 includes a second drive motor 24, a first roller brush 25, a second roller brush 26, and a support plate 27. The second drive motor 24 drives and connects to the first roller brush 25 and the second roller brush 26. A slide plate 28 is fixedly installed on the end face of the feeding conveyor 13, and a first scraper 29 is fixedly connected to the feeding conveyor 13 via a chain 30. The discharge conveyor belt 14 includes a chain plate 31 and a second scraper 32, with the chain plate 31 fixedly equipped with the second scraper 32. A main drive device 2 drives and connects to a first linkage device 33 and a second linkage device 34. The first linkage device 33 drives and connects to the feeding conveyor 13, and the second linkage device 34 drives and connects to the discharge conveyor belt 14. The bag blowing device 11 includes a bag blowing pipe 35 and an air nozzle plate 36. The bag blowing pipe 35 is provided with an air blowing port 37, and the air nozzle plate 36 is fixedly installed with an air blowing pipe 38.

[0028] Through the above technical solution, the translation linkage group 5 of the present invention rapidly translates to drive the bag-taking tray 6 and the bag-opening device 7 to reciprocate. The feeding conveying device 13 transfers the baked goods to the bag-taking tray 6. The bag-taking tray 6 and the bag-opening device 7 cooperate to enter the bag-delivering device 9. The bag-delivering device 9 blows open and inflates the packaging bag through the bag-blowing device 11, making it easier for the bag-taking tray 6 and the bag-opening device 7 to extend into the packaging bag. The bag-opening device 7 opens to cooperate with the bag-taking tray 6 to fix and remove the packaging bag. At this time, the bag-taking tray 6 and the bag-opening device 7 retract, and the baked goods are blocked by the blocking support rod 15. The bag-taking tray 6 and the bag-opening device 7 drive the packaging bag to fit the baked goods, completing the packaging process. The present invention completes the bagging process by driving the bag-taking tray 6 and the bag-opening device 7 to reciprocate in a linear and rapid manner through the translation linkage group 5, thereby improving production efficiency. Example

[0029] like Figures 1-10 As shown, the frame 1 of the present invention is fixedly equipped with the main drive device 2. The frame 1 is the basic structure of the automatic bagging machine. The frame 1 is made of steel to ensure the stability and durability of the entire machine. The main drive device 2 is one of the core components of the automatic bagging machine, responsible for providing power and driving the entire bagging process. The main drive unit 2 includes components such as a motor, reducer, and transmission belt to ensure smooth and precise control. The frame 1 is fixedly mounted with a packaging device 4 via a main beam plate 3. The main beam plate 3 is the main supporting frame of the packaging device 4 and is made of high-strength steel. The packaging device 4 is a structural component for packing baked goods into bags. The packaging device 4 includes a translation linkage group 5, a bag-lifting tray 6, and a bag-opening device 7. The main drive unit 2 drives and connects to the translation linkage group 5 via a main connecting rod 8. The translation linkage group 5 is fixedly mounted with the bag-lifting tray 6 and the bag-opening device 7. The translation linkage group 5 is the movable mechanism connecting the bag-lifting tray 6 and the bag-opening device 7. The bag-lifting tray 6 and the bag-opening device 7 are installed in the assembly part of the translation linkage group 5, and the assembly part is equipped with an assembly fixture. The fixed component is used to fix other structural components. The translation linkage group 5 consists of multiple linkages. The main drive device 2 drives the flywheel, which is connected to the main linkage 8. The main linkage 8 is connected to the translation linkage group 5, so that the assembly part of the translation linkage group 5 can move back and forth. The bag-retrieving plate 6 is located directly below the bag-opening device 7, and the ends of both are flush. The bag-retrieving plate 6 and the bag-opening device 7 work together to put the baked goods into the packaging bag and complete the packaging operation. The bag-retrieving plate 6 has two functions. The first is to support the baked goods to be packaged, and the second is to work with the bag-opening device 7 to open and fix the packaging bag. Specifically, the bag-retrieving plate 6 presses the bottom of the packaging bag from the inside of the packaging bag, while the bag-opening device 7 presses the top of the packaging bag from the inside of the packaging bag, so that the packaging bag is opened and fixed. A bag-handling device 9 is fixedly installed on the frame 1. The bag-handling device 9 is responsible for pre-opening the packaging bag to facilitate the bag-taking tray 6 and the bag-opening device 7 to extend into the packaging bag and complete the bag-taking operation. The bag-handling device 9 includes a fixed frame 10, a bag-blowing device 11, and a support plate. A blocking support rod 15 is fixedly installed on the frame 1 above the bag-taking tray 6. The blocking support rod 15 is used to block the baked goods on the bag-taking tray 6, so that the baked goods are stationary relative to the bag-taking tray 6, and the packaging bag grabbed by the bag-taking tray 6 and the bag-opening device 7 is put into the baked goods. The fixed frame 10 is used to support other components of the bag-handling device 9 to ensure its stable operation. The support plate is used to place the packaging bag, and the bag-blowing device 11 blows open and inflates the packaging bag. A feeding conveyor 13 and a discharging conveyor belt 14 are fixedly installed on the frame 1. The feeding conveyor 13 is responsible for conveying the baked goods to the bagging area. The discharging conveyor belt 14 is the output part of the automatic bagging machine, used to convey the bagged baked goods to the next production stage.

[0030] The specific working principle of this invention is as follows: the translation linkage group 5 drives the bag-picking plate 6 and the bag-opening device 7 to move to the bag-delivering device 9. At this time, the middle section of the bag-picking plate 6 is located at the outlet of the feeding conveyor 13, and the height of the bag-picking plate 6 is lower than that of the feeding conveyor 13. The feeding conveyor 13 then conveys a baked goods item and drops it onto the bag-picking plate 6. Simultaneously, the bag-picking plate 6 and the bag-opening device 7 also reach the inside of the bag-delivering device 9. The bag-delivering device 9 has pre-blown open a packaging bag, and the bag-picking plate 6 and the bag-opening device 7 directly extend into the packaging bag. The bag-opening device 7 opens and fixes the packaging bag, thus completing the process. After the operation is completed, the translation linkage group 5 begins to translate in the opposite direction (i.e., retract), driving the bag-retrieving plate 6 and the bag-opening device 7 to reset. At this time, the baked goods on the bag-retrieving plate 6 are blocked by the blocking support rod 15 and cannot move. The bag-retrieving plate 6 and the bag-opening device 7 continue to retract, allowing the packaging table to release the baked goods. The bottom of the packaging bag is blocked by the baked goods, causing the packaging bag to detach from the bag-retrieving plate 6 and the bag-opening device 7. At the same time, the packaged baked goods also detach from the bag-retrieving plate 6 and fall onto the discharge conveyor belt 14, completing the packaging of the baked goods.

[0031] This invention also includes an automatic control unit, comprising a PLC and a touchscreen interface. Operators can set machine parameters such as speed, bag type, and type of baked goods via the touchscreen, while the PLC coordinates all machine actions to ensure automation and accuracy in the bagging process. To ensure operator safety, the automatic bagging machine is also equipped with safety systems such as an emergency stop button and safety doors. These safety measures can quickly cut off power and stop the machine in an emergency, preventing accidental injury.

[0032] In this invention, a blocking support rod 15 is fixedly installed on the frame 1 above the bag-taking tray 6. The blocking support rod 15 is used to block the baked goods on the bag-taking tray 6, allowing the baked goods to be placed inside the packaging bag. The blocking support rod 15 is made of stainless steel or a corrosion-resistant alloy to ensure its stability and corrosion resistance during long-term operation. During the bagging process, the bag-taking tray 6 is responsible for supporting the baked goods to be packaged, while the blocking support rod 15 is located above the bag-taking tray 6 and is used to block the baked goods. When the bag-taking tray 6 and the bag-opening device 7 move to the bag-delivering device 9, the baked goods on the bag-taking tray 6 are blocked by the blocking support rod 15, ensuring that the baked goods are placed in the packaging bag. An adjusting cylinder 16 is fixedly installed on the blocking support rod 15. The blocking position of the blocking support rod 15 can be dynamically adjusted by adjusting the cylinder 16 to accommodate baked goods of different lengths. The adjusting cylinder 16 is a key component for realizing the dynamic adjustment of the blocking support rod 15, allowing for rapid adjustment of the blocking position of the blocking support rod 15 as needed. Operators can control the extension and retraction of the adjusting cylinder 16 via buttons or a touchscreen interface on the control panel. Before bagging, operators need to adjust the blocking position of the blocking rod 15 using the adjusting cylinder 16 according to the size of the baked goods to ensure smooth bagging. The automatic control unit of the automatic bagging machine can be integrated with the adjusting cylinder 16 to achieve automated adjustment. Controlled by a PLC program, the adjusting cylinder 16 can automatically adjust the position of the blocking rod 15 according to preset parameters, further improving the automation level of the bagging process. The adjusting cylinder 16 can employ various adjustment methods, such as linear adjustment, rotary adjustment, or tilt adjustment, to accommodate baked goods of different shapes and sizes. This multi-directional adjustment capability gives the automatic bagging machine greater flexibility and adaptability.

[0033] The bag-opening device 7 of the present invention includes an adjusting lever 17, a bag-opening plate 18, and a first drive motor 19. The adjusting lever 17 is the transmission structure between the first drive motor 19 and the bag-opening plate 18. The bag-opening plate 18 is the component that directly contacts the packaging bag and is responsible for opening the packaging bag to the appropriate position so that baked goods can be smoothly loaded. The first drive motor 19 is driven and connected to the first end of the adjusting lever 17 via a lead screw 20, and the first drive motor 19 is fixedly installed at the other end of the adjusting lever 17. The first drive motor 19 is the power source of the bag-opening device 7 and is responsible for driving the movement of the adjusting lever 17. The first drive motor 19 adopts a high-precision servo motor or stepper motor to control the opening force and opening degree of the bag-opening device 7, adapting to different types of packaging bags. The lead screw 20 is a mechanical element that converts rotary motion into linear motion. The lead screw 20 connects the first drive motor 19 and the adjusting lever 17. Through the transmission of the lead screw 20, the rotary motion of the first drive motor 19 can be accurately converted into the linear motion of the adjusting lever 17, precisely controlling the opening force and opening degree of the bag-opening plate 18. One end of the adjusting lever 17 is connected to the first drive motor 19 via a lead screw 20, while the other end is fixedly mounted on the bag-opening plate 18. This allows the adjusting lever 17 to function as a lever system, enabling precise control of the bag-opening plate 18 through the motor's drive. During the bagging process, the first drive motor 19 starts, driving the adjusting lever 17 to move via the lead screw 20, thereby controlling the bag-opening plate 18 to open the packaging bag.

[0034] The mounting frame 10 of this invention is fixedly equipped with an exchange slide 21. The mounting frame 10 is the supporting structure of the bag delivery device 9 and the basic structure supporting other components of the bag delivery device 9. The exchange slide 21 is a key component of the bag delivery device 9, used to automatically exchange the carrier plate 12 during the bagging process. The exchange slide 21 is driven by a lifting cylinder 22 to connect to the carrier plate 12. The lifting cylinder 22 is the power source that drives the exchange slide 21 to move up and down. Driven by the lifting cylinder 22, the exchange slide 21 can accurately lift the carrier plate 12 to the bag-taking opening of the bag delivery device 9, facilitating the bag-taking tray 6 and the bag-opening device 7 to take the packaged bag. The selection of the lifting cylinder 22 needs to be determined based on the weight of the exchange slide 21 and the required lifting speed. It needs to have sufficient force to support the exchange slide 21 and the carrier plate 12 and the packaged bag on it, while also ensuring rapid response to meet production efficiency requirements. During the bagging process, the exchange slide 21 lifts the carrier plate 12 to the bag-taking opening of the bag-handling device 9 so that the bag-opening device 7 and the bag-taking tray 6 can smoothly put the baked goods into the packaging bag.

[0035] The exchange slide 21 of this invention is fixedly equipped with two lifting cylinders 22, and each lifting cylinder 22 is driven and connected to a support plate 12. The exchange slide 21 is responsible for automatically exchanging the support plate 12 during the bagging process. The two lifting cylinders 22, each connected to a support plate 12, ensure the continuity and efficiency of the bagging process. The lifting cylinders 22 need not only sufficient force to support the exchange slide 21, its support plate 12, and the packaging bags, but also need to ensure rapid response to meet production efficiency requirements. The selection of the lifting cylinders 22 needs to comprehensively consider the weight of the exchange slide 21, the weight of the support plate 12, the weight of the packaging bags, and the required lifting speed. The exchange slide 21 needs sufficient rigidity and stability to support the lifting cylinders 22 and the support plate 12. In addition, guide rails or sliders are installed on the exchange slide 21 to ensure the smoothness and accuracy of the lifting cylinders 22 driving the support plate 12. During the bagging process, the lifting action of the exchange slide 21 is controlled by the lifting cylinders 22. When it is necessary to exchange the support plate 12, the lifting cylinder 22 will drive the support plate 12 to move upward, raising the support plate 12 containing baked goods to the bag-taking opening of the bag-handling device 9. At this time, the bag-opening device 7 and the bag-taking tray 6 can smoothly put the baked goods into the packaging bag. The two sets of support plates 12 can be used alternately to add packaging bags, improving production efficiency.

[0036] The function of the bag-sorting device 23 of this invention is to straighten the opening of the packaged baked goods bags, ensuring a neat bag opening for easy subsequent tying, thereby improving the cleanliness and aesthetics of the packaged baked goods. The bag-sorting device 23 consists of a second drive motor 24, a first roller brush 25, a second roller brush 26, and a support plate 27. The second drive motor 24 drives and connects the first roller brush 25 and the second roller brush 26, serving as the power source for the bag-sorting device 23. Through precise control, it drives the first roller brush 25 and the second roller brush 26 to rotate, thus straightening the bag opening. The first roller brush 25 is positioned directly above the second roller brush 26, allowing the two brushes to work together effectively to straighten the bag opening. During the bag-sorting process, the rotation speed of the second drive motor 24 can be adjusted according to the material and thickness of the packaging bag to accommodate different sizes. The distance between the first roller brush 25 and the second roller brush 26 also needs to be precisely adjusted according to the size of the packaging bag to ensure that the bag opening is effectively straightened as it passes between the two roller brushes.

[0037] The feeding conveyor 13 of this invention has a slide plate 28 fixedly installed on its end face. The slide plate 28 is used to receive baked goods. The slide plate 28 is made of stainless steel, which not only has excellent corrosion resistance and cleanability, but also can withstand wear and impact during daily use. To reduce the overall weight of the system without sacrificing the strength and stability of the slide plate 28, the thickness of the slide plate 28 is 1mm-3mm. By installing a bracket at the bottom of the slide plate 28, the rigidity and stability of the slide plate 28 are enhanced. This thickness ensures sufficient rigidity while reducing the weight of the entire conveying system. The surface of the slide plate 28 is smooth. The surface of the slide plate 28 is processed to be very smooth, which not only helps to reduce friction during the conveying process and prevent damage to the baked goods, but also facilitates cleaning and maintenance. The smooth surface can also reduce the adhesion of microorganisms, which is very important for maintaining the hygiene and quality of baked goods. The feeding conveyor 13 is fixedly connected to a first scraper 29 via a chain 30. The scraper scrapes over the slide plate 28, but does not directly contact the slide plate 28. This design can reduce noise and friction and extend the service life of the scraper and the slide plate 28. The scraper's function is to adjust the angle of the baked goods, ensuring they are parallel to the slide plate 28, thereby improving their neatness. By precisely adjusting the scraper's position and angle, operators can ensure that the baked goods are neatly arranged in the required direction and posture before entering the bagging area.

[0038] The discharge conveyor belt 14 of the present invention includes a chain plate 31 and a second scraper 32, with the chain plate 31 fixedly mounted with the second scraper 32. The cooperative use of the chain plate 31 and the second scraper 32 can achieve stable conveying of baked goods on the discharge conveyor belt 14. The continuous movement of the chain plate 31 drives the second scraper 32 to move synchronously. When the baked goods reach the end of the conveyor belt, the appropriate angle and position of the second scraper 32 can help the baked goods slide smoothly off the chain plate 31, avoiding the accumulation or falling of the baked goods and causing damage.

[0039] The main drive unit 2 of this invention drives and connects the first linkage device 33 and the second linkage device 34. The first linkage device 33 drives and connects the feeding conveyor device 13, and the second linkage device 34 drives and connects the discharging conveyor belt 14. The main drive unit 2 serves as the power source for the entire bagging process, responsible for driving the coordinated operation of various key components in the machine. The main drive unit 2 connects and drives the first linkage device 33 and the second linkage device 34 through a precision transmission system. These two linkage devices respectively control the feeding conveyor device 13 and the discharging conveyor belt 14, ensuring a smooth and efficient process for baked goods from entering the bagging area to completing bagging and output. The first linkage device 33 acts as a bridge connecting the main drive unit 2 and the feeding conveyor device 13. The main drive unit 2 drives the feeding conveyor device 13 through the first linkage device 33, while the second linkage device 34 is responsible for transmitting power from the main drive unit 2 to the discharging conveyor belt 14. Similar to the first linkage device 33, the second linkage device 34 also employs efficient transmission elements to ensure smooth power transmission and stable operation of the discharging conveyor belt 14.

[0040] The bag blowing device 11 of the present invention is a key component for pre-opening the packaging bag. It assists the bag filling process by controlling the airflow. The bag blowing device 11 includes a bag blowing pipe 35 and an air nozzle plate 36. The bag blowing pipe 35 is provided with an air blowing port 37. The air nozzle plate 36 is fixedly installed with an air blowing pipe 38. The air blowing pipe 38 is used to initially blow open the packaging bag, while the air blowing port 37 of the bag blowing pipe 35 continuously blows the packaging bag to ensure that the packaging bag is inflated.
