[0039] Reference Figures 1 to 3 The present application proposes a fully automatic bag opening device for flexible packaging materials, comprising:

[0040] Mounting seat 1;

[0041] A material storage mechanism 2, disposed on the mounting seat 1, for stacking flexible packaging materials;

[0042] The first transfer mechanism 3 includes a vertical driving member 31 disposed on the mounting seat 1 and a first material taking member 32 disposed at the output end of the vertical driving member 31, and the vertical driving member 31 is used to drive the first material taking member 32 to take out the flexible packaging material in the storage mechanism 2 along the vertical direction;

[0043] The bag opening mechanism 4 is arranged on the mounting seat 1 and located on one side of the material storage mechanism 2, and is used for opening the bag of the flexible packaging material;

[0044] The second transfer mechanism 5 is located on the side of the material storage mechanism 2 facing away from the bag opening mechanism 4, and includes a transverse driving assembly 51 arranged on the mounting seat 1 and a material receiving plate 52 arranged at the output end of the vertical driving member 31. The transverse driving assembly 51 is used to drive the material receiving plate 52 to move in the horizontal direction, so that the material receiving plate 52 transfers the flexible packaging material between the first material picking member 32 and the bag opening mechanism 4;

[0045] The unloading mechanism 6 is arranged on the mounting seat 1, and is used to take out the opened flexible packaging material on the receiving plate 52 and unload the material.

[0046] In this embodiment, the coordinated work of multiple mechanisms of the present application realizes the automatic opening of flexible packaging materials, wherein the storage mechanism 2 is used to store flexible packaging materials, and the materials can be stacked into the storage mechanism 2 manually or by a manipulator. The vertical drive member 31 in the first transfer mechanism 3 drives the first material taking member 32 to move in the vertical direction, and can vertically take out the flexible packaging materials from the storage mechanism 2. The bag opening mechanism 4 can use a specific mechanical structure or physical method (such as a suction cup, a clamp 8, etc.) to open the bag of the flexible packaging material. The transverse drive assembly 51 of the second transfer mechanism 5 drives the material receiving plate 52 to move in the horizontal direction, realizing the transfer of flexible packaging materials between the first material taking member 32 and the bag opening mechanism 4. This is based on the displacement control principle in the horizontal direction, ensuring that the materials can accurately flow between different stations. The unloading mechanism 6 takes out and unloads the opened flexible packaging materials through a corresponding mechanical structure (such as a manipulator, a multi-axis module, etc.).

[0047] Specifically, the working process of the fully automatic bag opening device for flexible packaging materials of the present application can be briefly described as follows:

[0048] Material picking process: First, the flexible packaging materials in the storage mechanism 2 are stacked and stored manually or by a robot, and the vertical driving member 31 of the first transfer mechanism 3 works to drive the first material picking member 32 to move downward in the vertical direction. When the first material picking member 32 reaches the appropriate position, it grabs (such as by adsorption, clamping, etc.) the flexible packaging materials in the storage mechanism 2, and then the vertical driving member 31 drives the first material picking member 32 to move upward to take the flexible packaging materials out of the storage mechanism 2.

[0049] Transfer process: The transverse driving assembly 51 of the second transfer mechanism 5 starts to work, driving the receiving plate 52 to move horizontally from the position of the first material picking member 32 to the direction of the bag opening mechanism 4. When the receiving plate 52 reaches the bottom of the first material picking member 32 (or the corresponding handover position), the first material picking member 32 places the flexible packaging material on the receiving plate 52, and then the receiving plate 52 continues to move toward the bag opening mechanism 4 to transport the flexible packaging material to the bag opening mechanism 4.

[0050] Bag opening process: After the receiving plate 52 transports the flexible packaging material to the position of the bag opening mechanism 4, the bag opening mechanism 4 performs bag opening operation on the flexible packaging material. For example, the bag opening can be opened by mechanical grippers 8, or by suction cups to absorb the bag opening and open it, etc., which are only exemplary and non-limiting.

[0051] Unloading process: After the bag opening mechanism 4 completes the bag opening, the unloading mechanism 6 starts to work. The unloading mechanism 6 takes out the opened flexible packaging material from the receiving plate 52, and then completes the unloading by its own unloading method (such as placing the material on a conveyor belt for transportation, etc.).

[0052] The present application improves the efficiency of opening the bags of flexible packaging materials by setting up the fully automatic bag opening device of the flexible packaging material structure, realizes the automatic bag opening operation, and greatly improves the speed and efficiency of bag opening compared with manual bag opening. The flexible packaging material can be quickly taken out from the storage mechanism 2 for bag opening and unloading, which reduces the time and labor intensity of manual operation.

[0053] Reference Figures 1 to 3 In some embodiments, the storage mechanism 2 proposed in the embodiment of the present application includes a supporting plate 21 arranged on the mounting seat 1, and a plurality of enclosures 22 arranged at intervals along the entire circumference of the supporting plate 21, and a storage space for stacking flexible packaging materials is formed between the supporting plate 21 and the plurality of enclosures 22.

[0054] In this embodiment, the carrier plate 21 serves as a bottom support structure, providing a stable placement plane for the flexible packaging material. A plurality of enclosures 22 are spaced along the entire circumference of the carrier plate 21, and together with the carrier plate 21, form a containing space. When the flexible packaging material is placed in this containing space, the enclosures 22 limit the horizontal movement of the material, so that the material can be stacked in this relatively closed space.

[0055] When adding flexible packaging materials to the accommodating space, the materials can be naturally stacked on the carrying plate 21 under the action of gravity. Due to the restriction of the enclosure 22, the materials will gradually accumulate into a neat stack state in the accommodating space. Moreover, the design of the enclosure 22 with intervals makes it convenient to observe and operate the materials from all directions (for example, from the top of the stack).

[0056] In some embodiments, when it is necessary to accommodate flexible packaging materials of different sizes, the enclosure 22 can be designed as a height-adjustable structure. For thinner flexible packaging materials, the height of the enclosure 22 is lowered to make it easier for the material to be accessed; for thicker materials or a large amount of stacked materials, the height of the enclosure 22 is increased to accommodate more materials. The spacing between the enclosures 22 can also be adjusted. If the size of the flexible packaging material varies greatly in the length or width direction, the spacing between the enclosures 22 can be adjusted so that the accommodating space can better adapt to the shape of the material. For example, for long and narrow materials, the spacing between the enclosures 22 in the length direction can be increased while reducing the spacing in the width direction.

[0057] Reference Figures 1 to 3 In some embodiments, the first transfer mechanism 3 proposed in the embodiment of the present application further includes a cantilever 33, the cantilever 33 is connected to the output end of the vertical driving member 31, and the cantilever 33 is horizontally arranged;

[0058] There are multiple first material picking members 32 , and the multiple first material picking members 32 are horizontally spaced apart along the cantilever 33 .

[0059] In this embodiment, the vertical driving member 31 serves as a power source, and its output end is connected to the cantilever 33. When the vertical driving member 31 is working, the cantilever 33 can be driven to move in the vertical direction. Since the cantilever 33 is arranged horizontally, multiple first material picking members 32 arranged horizontally at intervals along the cantilever 33 can remain stable at the same horizontal height. During the material picking process, the vertical driving member 31 drives the cantilever 33 to move downward, so that the first material picking members 32 can reach the appropriate position of the flexible packaging material in the storage mechanism 2. Each first material picking member 32 can contact and grab the flexible packaging material by adsorption (such as a vacuum suction cup) or clamping (such as a mechanical clamp 8). Because there are multiple first material picking members 32, multiple flexible packaging materials can be grabbed at the same time, or for a single flexible packaging material with a larger area, a more stable grab can be performed through multiple contact points.

[0060] A plurality of first material picking members 32 are arranged horizontally and spaced apart along the cantilever 33. This arrangement enables a certain horizontal range to be covered when grabbing the flexible packaging material. The spacing between the first material picking members 32 can be adjusted according to the size and shape of the flexible packaging material to achieve the best grabbing effect. For example, for long strips of flexible packaging material, the spacing between the first material picking members 32 can be set larger so that the material can be grabbed along the length direction, ensuring that the flexible packaging material is evenly stressed when being lifted, and the material will not be damaged or deformed due to excessive stress at a single point.

[0061] The present application achieves the following effects by setting the first transfer mechanism 3 of the above structure:

[0062] First, the grabbing efficiency is improved: the design of multiple first material grabbing members 32 can grab multiple flexible packaging materials at one time, which greatly improves the efficiency of material grabbing compared to a single material grabbing member. In particular, when a large amount of flexible packaging materials needs to be processed, the number of material grabbing can be reduced, thereby speeding up the workflow of the entire device.

[0063] Second, it can adapt to materials of different sizes: the first material picking members 32 are arranged horizontally and spaced along the cantilever 33 so that the mechanism can adapt to flexible packaging materials of different sizes. For materials of smaller sizes, fewer material picking members can be used for grabbing by adjusting the intervals between the first material picking members 32; for materials of larger sizes, all the material picking members can participate in grabbing to ensure that the materials can be firmly grasped. This flexibility enables the device to handle flexible packaging materials of various specifications, improving the versatility of the device.

[0064] Reference Figures 1 to 3 In some embodiments, each first material picking member 32 proposed in the embodiments of the present application is slidably connected to the cantilever 33, and two adjacent first material picking members 32 can move horizontally toward or away from each other along the cantilever 33.

[0065] In this embodiment, since two adjacent first material picking members 32 can move horizontally toward or away from each other along the cantilever 33, the spacing between the first material picking members 32 can be flexibly adjusted. When it is necessary to grab a smaller flexible packaging material, the first material picking members 32 can move toward each other to reduce the spacing between them. In this way, the material picking members can closely fit the size of the material, and only part of the material picking members or a more appropriate distribution method are used to grab the material, so as to avoid the inability to effectively grab small-sized materials due to the large spacing between the material picking members.

[0066] For flexible packaging materials with larger sizes, the first pick-up members 32 move in opposite directions to increase the distance between them. In this way, the pick-up members can be distributed at appropriate positions on the material to ensure that they can grab the edge or key parts of the material. For example, for flexible packaging materials with larger widths, by adjusting the distance between the pick-up members, they can grab both sides of the material, provide sufficient support and grabbing force, and prevent the material from being deformed or damaged due to uneven force during the lifting process.

[0067] The first pick-up member 32 can slide to adjust its position, which is beneficial to optimizing the distribution of the gripping force on the flexible packaging material. For materials with uneven texture or special center of gravity distribution, the gripping force can be reasonably distributed to various key parts of the material by adjusting the position of the pick-up member. For example, for some flexible packaging materials that are heavier on one side, more first pick-up members 32 are distributed on the heavier side or the position is adjusted so that the pick-up member on this side provides a greater gripping force, thereby ensuring that the material can remain horizontal when being lifted to avoid tilting or falling. This is only an exemplary description.

[0068] Reference Figures 1 to 3 In some embodiments, the transverse driving assembly 51 proposed in the embodiment of the present application includes:

[0069] The first transverse driving member 511 is disposed on the mounting seat 1 , and the output end of the first transverse driving member 511 is connected to the material receiving plate 52 to drive the material receiving plate 52 to move toward the first material picking member 32 and the bag opening mechanism 4 along the horizontal direction.

[0070] In this embodiment, the first transverse driving member 511 effectively realizes the horizontal movement of the receiving plate 52, thereby completing the transfer of the flexible packaging material between the first material picking member 32 and the bag opening mechanism 4. The flexible packaging material can be smoothly transported from the material picking position to the bag opening position, so that the workflow of the entire device can be carried out continuously.

[0071] Before the device is started, the material receiving plate 52 is in the initial position, the first transverse driving member 511 is in a standby state, and the entire device is waiting for the processing of the flexible packaging material. At this time, the flexible packaging material has been stacked in the storage mechanism 2.

[0072] When the vertical driving member 31 of the first transfer mechanism 3 drives the first material taking member 32 to take out the flexible packaging material from the material storage mechanism 2, the control system sends a command to the first transverse driving member 511 to start working.

[0073] After receiving the command, the first transverse driving member 511 starts to operate, driving the receiving plate 52 to start moving horizontally toward the position of the first picking member 32. The receiving plate 52 moves to the position directly below the first picking member 32 or to the corresponding intersection position to receive the flexible packaging material grabbed by the first picking member 32.

[0074] When the material receiving plate 52 reaches the specified position and the first material picking component 32 places the flexible packaging material on the material receiving plate 52, the first transverse driving component 511 receives the instruction from the control system again, and starts to drive the material receiving plate 52 to move in the direction of the bag opening mechanism 4, transporting the flexible packaging material to the operating position of the bag opening mechanism 4, preparing for the subsequent bag opening operation of the bag opening mechanism 4 on the flexible packaging material.

[0075] Reference Figures 1 to 3 In some embodiments, the transverse drive assembly 51 provided in the embodiment of the present application further includes:

[0076] The second transverse driving member 512 is disposed at the output end of the first transverse driving member 511 . The output end of the second transverse driving member 512 is connected to the material receiving plate 52 to drive the material receiving plate 52 to move horizontally toward the first material picking member 32 and the bag opening mechanism 4 .

[0077] In this embodiment, based on the aforementioned first transverse driving member 511, the second transverse driving member 512 is installed at the output end of the first transverse driving member 511, and its output end is connected to the receiving plate 52, so that the horizontal movement of the receiving plate 52 is controlled by the two driving members. The first transverse driving member 511 is mainly responsible for providing a large range of horizontal displacement drive, while the second transverse driving member 512 can make a more precise adjustment on the position of the receiving plate 52 based on the first transverse driving member 511.

[0078] After the first transverse driving member 511 moves the material receiving plate 52 roughly to the target area (close to the first material picking member 32 or the bag opening mechanism 4), the second transverse driving member 512 starts to work, and generates a horizontal driving force through its own driving mechanism, further adjusting the position of the material receiving plate 52 so that it can more accurately dock with the first material picking member 32 or accurately deliver the flexible packaging material to the operating position of the bag opening mechanism 4.

[0079] Reference Figures 1 to 3 In some embodiments, the fully automatic bag opening device for flexible packaging materials proposed in the embodiment of the present application further comprises a mounting frame slidably connected to the mounting seat 1; a material receiving plate 52 is arranged on the mounting frame, and a avoiding hole is opened on the material receiving plate 52;

[0080] The second transverse driving member 512 is arranged on the mounting frame, and the transverse driving assembly 51 also includes a conveying belt 513 which is transmission-connected to the second transverse driving member 512 . The conveying belt 513 is arranged in the avoidance hole, and the conveying belt 513 is exposed on the upper side of the receiving plate 52 .

[0081] In this embodiment, the design of the mounting frame slidingly connected to the mounting seat 1 is to provide a basic support structure for the material receiving plate 52 to move in the horizontal direction, and at the same time enable the material receiving plate 52 to move flexibly on the mounting seat 1. This sliding connection method can be implemented by using a guide rail slider structure or a linear slide rail. For example, a guide rail is set on the mounting seat 1, and a matching slider is installed at the bottom of the mounting frame. In this way, the mounting frame can slide smoothly horizontally along the guide rail, thereby driving the material receiving plate 52 to move in the horizontal direction to meet the material transfer requirements between the first material picking member 32 and the bag opening mechanism 4. This is only an exemplary description.

[0082] The receiving plate 52 is arranged on the mounting frame to carry the flexible packaging material, and the avoidance holes are provided to provide installation space for the conveying belt 513 and avoid interference between the conveying belt 513 and the receiving plate 52 structure.

[0083] The conveyor belt 513 is arranged in the avoidance hole and exposed on the upper side of the receiving plate 52, and is mainly used to realize the short-distance transportation of the flexible packaging material on the receiving plate 52. When the second transverse driving member 512 accurately positions the receiving plate 52 to the position where it intersects with the first material picking member 32 or the operating position of the bag opening mechanism 4, the conveyor belt 513 can be driven by the second transverse driving member 512 to move therewith, so as to drive the flexible packaging material to move relative to the receiving plate 52 to approach the bag opening mechanism 4.

[0084] In some implementations, when the bag to be opened is a self-sealing bag such as a bone buckle bag, the bone buckle sensor 200 can be set as a detection device to guide the second transverse driving member 512 to work, so as to indicate the transportation position of the flexible packaging material, for example, whether it is correctly transported to the bag opening mechanism 4. Further, a bag opening sensor 300 can be set as a bag opening position detection device to detect whether the bag opening position is correctly located between the upper and lower suction cups or whether the bag opening is correctly opened, which is only an exemplary description.

[0085] Reference Figures 1 to 3 In some embodiments, the unloading mechanism 6 proposed in the embodiment of the present application includes a unloading drive component 61 arranged on the mounting seat 1 and a material picking suction cup 62 arranged at the output end of the unloading drive component 61, the unloading drive component 61 is used to drive the material picking suction cup 62 to approach or move away from the flexible packaging material on the supporting plate 21, and the material picking suction cup 62 is used to adsorb the flexible packaging material.

[0086] In this embodiment, the material removal drive assembly 61 is installed on the mounting base 1, and can drive the material picking suction cup 62 arranged at its output end to move in the vertical direction (the direction approaching or moving away from the flexible packaging material on the supporting plate 21). The material picking suction cup 62 grabs the flexible packaging material based on the principle of negative pressure adsorption. When the material picking suction cup 62 contacts the surface of the flexible packaging material, a negative pressure environment is formed inside the suction cup by connecting to an external vacuum device (such as a vacuum pump). Under the action of the external atmospheric pressure, the flexible packaging material is tightly adsorbed on the surface of the suction cup, thereby achieving the grasping of the material. This adsorption method is a relatively gentle and effective grasping method for flexible packaging materials, which can avoid damage to the material.

[0087] After the flexible packaging material on the receiving plate 52 has completed the bag opening operation, the unloading drive assembly 61 receives the command of the control system and starts to work. It generates a downward driving force through the internal driving mechanism to drive the material taking suction cup 62 to approach the flexible packaging material on the receiving plate 52 along the vertical direction.

[0088] When the material taking suction cup 62 contacts the surface of the flexible packaging material, the external vacuum device is activated to form a negative pressure inside the suction cup. Under the action of atmospheric pressure, the flexible packaging material is adsorbed on the suction cup. At this time, the material unloading drive component 61 will maintain a certain pressure to ensure that the suction cup and the material are firmly adsorbed to prevent the material from falling off during the subsequent unloading process.

[0089] After the material is firmly adsorbed, the unloading drive assembly 61 works again to generate an upward driving force, driving the material-collecting suction cup 62 to carry the adsorbed flexible packaging material upward away from the receiving plate 52. Then, according to the unloading layout of the device (such as placing the material on a conveyor belt or a specific collection container), the unloading drive assembly 61 will move the material-collecting suction cup 62 to the corresponding unloading position. When the unloading position is reached, the vacuum device stops working, the internal pressure of the suction cup returns to normal, and the material is separated from the suction cup under the action of its own gravity or other auxiliary unloading devices (such as a blowing device), completing the unloading.

[0090] Reset stage: After the unloading is completed, the unloading drive component 61 drives the material picking suction cup 62 to return to the initial position and wait for the next unloading instruction, and this cycle is repeated to achieve continuous unloading operation.

[0091] The present application realizes an automated driving and adsorption mode by setting up the unloading mechanism 6 of the above structure, which can quickly and accurately remove the opened flexible packaging material on the receiving plate 52 and place it at a designated position, greatly improving the unloading efficiency.

[0092] In some embodiments, the material unloading drive assembly 61 can be a multi-axis robot, or it can be a material picking robot arm structure composed of three-axis, Y-axis, and Z-axis modules or more, which is only used as an example here.

[0093] Reference Figures 1 to 3 In some embodiments, the bag opening mechanism 4 proposed in the embodiment of the present application includes:

[0094] An upper suction cup 41 and a lower suction cup 42 are arranged opposite to each other in a vertical direction and are used to absorb the flexible packaging material.

[0095] The upper driving member 43 and the lower driving member 44, the output ends of which are respectively connected to the upper suction cup 41 and the lower suction cup 42, are used to drive the upper suction cup 41 and the lower suction cup 42 to move in opposite directions to open the bag mouth of the flexible packaging material.

[0096] In this embodiment, the upper suction cup 41 and the lower suction cup 42 are based on the negative pressure adsorption principle to grasp the flexible packaging material. When the suction cup contacts the surface of the packaging material, a negative pressure environment is formed inside the suction cup by connecting to an external vacuum device (such as a vacuum pump). Under the action of the external atmospheric pressure, the packaging material is tightly adsorbed on the surface of the suction cup. The upper and lower suction cups 42 are arranged relative to each other in the vertical direction and can be adsorbed on the upper and lower parts of the bag opening of the packaging material respectively.

[0097] The upper driving member 43 and the lower driving member 44 are connected to the upper suction cup 41 and the lower suction cup 42 respectively, and they can be devices that can generate linear motion, such as a cylinder, an electric push rod or a screw motor. When the driving members are working, they will generate driving forces in opposite directions, so that the upper suction cup 41 and the lower suction cup 42 move in opposite directions. In this way, the bag opening is pulled open by utilizing the adsorption force between the suction cup and the packaging material, thereby realizing the bag opening operation.

[0098] When the receiving plate 52 transports the flexible packaging material to the position of the bag opening mechanism 4, it is expected that the flexible packaging material extends between the upper and lower suction cups 42, and the upper suction cup 41 and the lower suction cup 42 move downward and upward (or other suitable movement modes) through the driving members connected to each other under the command of the control system, so that they contact the upper and lower parts of the bag opening of the flexible packaging material. Then, the external vacuum equipment is started to form a negative pressure inside the upper and lower suction cups 42, and the upper and lower parts of the bag opening of the packaging material are respectively adsorbed on the upper and lower suction cups 42. After the bag opening is firmly adsorbed, the upper driving member 43 and the lower driving member 44 of the bag opening drive assembly start to work. The upper driving member 43 drives the upper suction cup 41 to move upward, and the lower driving member 44 drives the lower suction cup 42 to move downward, and the opposite driving forces generated gradually open the bag opening.

[0099] Bag opening completion stage: When the bag opening is opened to a sufficient extent, the bag opening drive assembly stops working. At this time, the upper suction cup 41 and the lower suction cup 42 still absorb the bag opening to keep the bag opening open until other mechanisms (such as the filling mechanism, etc.) complete the corresponding operation or the bagged material needs to be transferred, and then the suction cup releases the bag opening under the command of the control system.

[0100] In some embodiments, the Figure 2 A bag blowing mechanism 100 is provided to blow the bag opening flat, so that the bag opening is flat and convenient for adsorption.

[0101] Reference Figures 1 to 3 In some embodiments, the fully automatic bag opening device for flexible packaging materials provided in the embodiments of the present application further comprises a bag clamping driving member 7, a clamping claw 8, a bag pressing driving member 9 and a bag pressing member 10, wherein:

[0102] The bag clamping driving member 7 is arranged on the upper side of the upper suction cup 41, and the clamping claw 8 is arranged at the output end of the bag clamping driving member 7. The bag clamping driving member 7 is used to drive the clamping claw 8 to move in the horizontal direction and / or the vertical direction, and the clamping claw 8 is used to clamp the upper bag opening of the flexible packaging material;

[0103] The bag pressing driving component 9 is arranged between the upper suction cup 41 and the lower suction cup 42, and the bag pressing component 10 is arranged at the output end of the bag pressing driving component 9. The bag pressing driving component 9 is used to drive the bag pressing component 10 to move horizontally to extend into the flexible packaging material with the bag opening opened, and drive the bag pressing component 10 to be crimped to the lower bag opening of the flexible packaging material.

[0104] In this embodiment, after the receiving plate 52 transports the flexible packaging material to the bag opening mechanism 4, the upper suction cup 41 and the lower suction cup 42 firstly absorb the upper and lower parts of the bag opening of the flexible packaging material according to the method described in the above embodiment.

[0105] First, the bag opening drive assembly (upper drive member 43 and lower drive member 44) starts to work, driving the upper suction cup 41 and the lower suction cup 42 to move in opposite directions, and opening the bag. In this process, the clamping jaw 8 maintains a clamping state on the bag opening under the action of the bag clamping drive member 7, ensuring that the bag opening can be opened smoothly.

[0106] Secondly, the bag clamping driving member 7 starts to work, driving the clamping jaws 8 to move horizontally toward the bag opening. When the clamping jaws 8 reach a suitable position, they clamp the upper bag opening of the flexible packaging material. At this time, the clamping jaws 8 and the upper suction cup 41 can act together on the upper bag opening, enhancing the control force on the upper bag opening, making the bag opening more stable during the subsequent bag opening and operation process.

[0107] Then, the bag clamping driving member 7 drives the clamping jaws 8 holding the upper bag opening to move away from the lower bag opening to further open the upper and lower bag openings of the flexible packaging material. Exemplarily, this operation is usually used to further tear open the bag opening of the flexible packaging material to avoid the problem of the bag opening sticking or insufficient opening.

[0108] The present application realizes the bag opening operation for flexible packaging materials of different materials and thicknesses by setting up the above-mentioned structure. Through the coordinated operation of various components, the state of the bag opening can be controlled more accurately, thereby improving the accuracy of the entire bag opening and subsequent operations.

[0109] In some embodiments, the bag clamping drive 7 and the bag pressing drive 9 can be drives composed of cylinders in multiple directions, such as vertical cylinders or horizontal cylinders, or rotary cylinders. Those skilled in the art can set them according to actual needs.

All equivalent structural changes made using the contents of the present application specification and drawings under the overall concept of the present application, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.
