At the same time, the presence of the filter screen also helps to reduce the dust flying during the discharging process, protecting the environment and the health of the operators.

[0035] In summary, installing a filter screen on the discharge valve is an effective measure, which can ensure the quality of the powdered sugar, prevent impurities from mixing in, and reduce dust pollution. This design has important significance for the processing and collection of powdered sugar;

[0052] Lifting drive assembly: It includes a third servo motor 7131, a connecting rod member 7132, and a spur gear 7133, which are used to control the vertical movement of the toothed plate 714 to ensure that the material can be smoothly pushed into the hopper after cutting, avoiding debris caused by improper movement.

[0065] The working principle of the above embodiment is as follows:

[0066] Place bulk materials such as powdered sugar to be bag-opened on the conveying table 1. The conveying table 1 uses a conveyor belt or other conveying device to smoothly convey the materials to the designated position. During the conveying process, the position and state of the materials can be monitored and fed back through sensors or other detection devices to ensure that the materials accurately reach the designated position. When the materials reach the designated position, the high-speed cutting machine 6 is started. The cutting blade or other cutting tools of the high-speed cutting machine 6 rotate rapidly to accurately cut the powdered sugar bag. During the cutting process, parameters such as the cutting speed, cutting depth, and cutting angle of the cutting machine can be adjusted according to the characteristics and requirements of the materials to ensure the cutting effect and quality, and the generation of debris can be reduced or eliminated during the cutting process, thereby maintaining the cleanliness and safety of the working environment. The clamping drive assembly of the stable pushing mechanism 700 starts to work. The first servo motor 7021 in the clamping drive assembly drives the first threaded rod member 7022 to rotate, causing the threaded sleeve 703 to move along the axial direction of the first threaded rod member 7022. The movement of the threaded sleeve 703 drives the support member 705 and the clamping and pushing assembly to move together, bringing the clamping and pushing assembly closer to the bagged powdered sugar. The electric cylinder 7061 in the clamping and pushing assembly is started to push the abutting plate 7062 towards the bagged powdered sugar. After the abutting plate 7062 contacts the bagged powdered sugar, the electric cylinder 7061 continues to apply pressure to tightly clamp the bagged powdered sugar with the abutting plate 7062. The magnitude of the clamping force can be controlled by adjusting the pressure of the electric cylinder 7061 to ensure that the bagged powdered sugar does not fall or get damaged during the clamping process. The second servo motor 7092 in the pushing drive assembly is started to drive the second threaded rod member 7093 to rotate. The rotation of the second threaded rod member 7093 causes the moving block 710 to move along the axial direction of the second threaded rod member 7093 within the regulation box 708. The movement of the moving block 710 drives the hollow connecting block 711, the lifting drive assembly, and the toothed plate 714 to move together, pushing the bagged powdered sugar above the collection box 2. The third servo motor 7131 in the lifting drive assembly is started to drive the connecting rod member 7132 and the spur gear 7133 to rotate. The rotation of the spur gear 7133 meshes with the toothed plate 714, causing the toothed plate 714 to move vertically within the hollow connecting block 711. The movement of the toothed plate 714 drives the pusher 718 to descend and push the materials onto the high-speed cutting machine 6 through the pusher 718. After the cutting operation on the bagged powdered sugar, the powdered sugar will enter the hopper by pouring. At this time, the discharge valve 4 will be opened to discharge and collect the powdered sugar into the designated collection box 2, preventing impurities such as bags from being discharged from the discharge valve 4 along with the powdered sugar. The filter screen 8 can effectively block larger objects such as bags, ensuring that only the powdered sugar can pass through the discharge 4 and enter the collection box 2, thus preventing impurities such as bags from mixing into the powdered sugar. In addition, the filter screen 8 can also play a role in filtering and screening, preventing possible small pieces of impurities or foreign objects from entering the collection box. At the same time, the filter screen 8 helps to reduce the dust flying during the discharging process, thereby ensuring that the materials can be smoothly discharged. Once the materials are discharged from the collection box 2,The entire bag-opening process is completed. The conveying table 1 can continue to convey the next batch of materials to be bag-opened and repeat the above steps to achieve continuous bag-opening operations.

[0067] Compared with the prior art: This automatic bag opener can provide a function of high-speed rotating cutting of powdered sugar bags through the mutual cooperation of the collection box 2, the diversion table 3, the discharge valve 4, the support plate 5, the high-speed cutting machine 6 and the stable pushing mechanism 700 on the conveying table 1. It can complete the bag-opening operation quickly and accurately without generating outer bag debris, effectively avoiding the impact of debris on product quality. At the same time, this device can also automatically pour the internal materials into the hopper, reducing manual operation, improving production efficiency and safety. In addition, this device also has the function of avoiding wrinkles, which can ensure the integrity and stability of the materials, improving product quality and production efficiency, and solving the problems of easy generation of debris, inability to effectively filter foreign objects and the need for manual operation in the existing bag-opening equipment.

[0068] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technology and the provision of the power supply also belong to the common knowledge in this field. Therefore, this application will not be elaborated in detail.
