[0039] With reference to Figures 1 to 3 , the present application proposes a full-automatic bag opening device for flexible packaging material, comprising:

[0040] a mounting seat 1;

[0041] a storage mechanism 2 arranged on the mounting seat 1 and used for stacking the flexible packaging material;

[0042] a first transfer mechanism 3 comprising a vertical driving member 31 arranged on the mounting seat 1 and a first material taking member 32 arranged on the output end of the vertical driving member 31, the vertical driving member 31 being 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] a bag opening mechanism 4 arranged on the mounting seat 1 and located on one side of the storage mechanism 2, and used for performing bag opening operation on the flexible packaging material;

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

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

[0046] In this embodiment, the multiple mechanisms of the present application work together to realize automatic bag opening of the flexible packaging material. The storage mechanism 2 is used to store the flexible packaging material, which can be stacked into the storage mechanism 2 by manual or mechanical hand. The vertical driving member 31 in the first transfer mechanism 3 drives the first material taking member 32 to move in the vertical direction, which can take out the flexible packaging material from the storage mechanism 2 vertically. The bag opening mechanism 4 can use a specific mechanical structure or physical method (such as a suction cup, a clamping jaw 8, etc.) to open the bag of the flexible packaging material. The horizontal movement driving assembly 51 of the second transfer mechanism 5 drives the receiving plate 52 to move in the horizontal direction, which realizes the transfer of the flexible packaging material 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, which ensures that the material can accurately flow between different stations. The unloading mechanism 6 takes out and unloads the bagged flexible packaging material through a corresponding mechanical structure (such as a mechanical hand, a multi-axis module, etc.).

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

[0048] The material taking process: first, the flexible packaging material in the storage mechanism 2 is stacked and stored by manual or mechanical hand. The vertical driving member 31 of the first transfer mechanism 3 works to drive the first material taking member 32 to move downward in the vertical direction. When the first material taking member 32 reaches the appropriate position, it grabs (such as by adsorption, clamping, etc.) the flexible packaging material in the storage mechanism 2. Then the vertical driving member 31 drives the first material taking member 32 to move upward, taking out the flexible packaging material from the storage mechanism 2.

[0049] The transfer process: the horizontal movement driving assembly 51 of the second transfer mechanism 5 starts to work to drive the receiving plate 52 to move horizontally from the position of the first material taking member 32 to the bag opening mechanism 4. When the receiving plate 52 reaches the position below the first material taking member 32 (or the corresponding transfer position), the first material taking member 32 places the flexible packaging material on the receiving plate 52. Then the receiving plate 52 continues to move to the bag opening mechanism 4 to transport the flexible packaging material to the bag opening mechanism 4.

[0050] Opening process: after the flexible packaging material is transported to the position of the opening mechanism 4 by the receiving plate 52, the opening mechanism 4 performs the opening operation on the flexible packaging material. For example, the bag opening can be pulled by mechanical clamps 8, or the bag opening can be pulled by using a suction cup to suck the bag opening, and the like, which are only exemplary and not limiting.

[0051] Discharging process: after the opening mechanism 4 completes the opening, the discharging mechanism 6 starts to work. The discharging mechanism 6 takes out the opened flexible packaging material from the receiving plate 52, and then completes the discharging by its own discharging mode (such as placing the material on a conveyor belt to be transported away, etc.).

[0052] The present application improves the opening efficiency of the flexible packaging material by setting the above-mentioned flexible packaging material full-automatic opening device, realizes automatic opening operation, and greatly improves the opening speed and efficiency compared with manual opening. The flexible packaging material can be quickly taken out from the storage mechanism 2, opened and discharged, reducing the time and labor intensity of manual operation.

[0053] Reference Figures 1 to 3 In some embodiments, the storage mechanism 2 proposed in the embodiments of the present application includes a bearing plate 21 arranged on the mounting seat 1, and a plurality of surrounding plates 22 arranged along the whole circumference of the bearing plate 21 at intervals. The bearing plate 21 and the plurality of surrounding plates 22 form a containing space for stacking flexible packaging materials.

[0054] In the present embodiment, the bearing plate 21 serves as a bottom support structure and provides a stable placement plane for the flexible packaging material. The plurality of surrounding plates 22 are arranged along the whole circumference of the bearing plate 21 at intervals and together with the bearing plate 21 form a containing space. When the flexible packaging material is placed in the containing space, the surrounding plates 22 restrict the movement of the material in the horizontal direction, so that the material can be stacked in the relatively closed space.

[0055] When adding flexible packaging materials to the containing space, the materials can be naturally stacked on the bearing plate 21 under the action of gravity. Due to the restriction of the surrounding plates 22, the materials will gradually accumulate in the containing space to form a neat stack. Moreover, the design of the surrounding plates 22 arranged at intervals makes it convenient to observe and operate the materials from various directions (for example, from above the stack).

[0056] In some embodiments, when flexible packaging materials of different sizes need to be accommodated, the surrounding plates 22 can be designed as height-adjustable structures. For thinner flexible packaging materials, the height of the surrounding plates 22 is lowered so that the material is more easily accessible to the material taking members; for thicker materials or a large number of stacked materials, the height of the surrounding plates 22 is increased to accommodate more materials. The spacing of the surrounding plates 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 surrounding plates 22 can be adjusted so that the accommodation space can better adapt to the shape of the material. For example, for long and narrow materials, the spacing of the surrounding plates 22 in the length direction can be increased, while the spacing in the width direction can be reduced.

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

[0058] The first material taking members 32 are multiple, and the multiple first material taking members 32 are horizontally spaced along the cantilever 33.

[0059] In the 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 works, it can drive the cantilever 33 to move in the vertical direction. Since the cantilever 33 is horizontally arranged, the multiple first material taking members 32 horizontally spaced along the cantilever 33 can remain stable at the same horizontal height. During the material taking process, the vertical driving member 31 drives the cantilever 33 to move downward, so that the first material taking members 32 can reach the appropriate position of the flexible packaging material in the material storage mechanism 2. Each first material taking member 32 can contact and grasp the flexible packaging material through adsorption (such as a vacuum suction cup) or clamping (such as a mechanical clamping jaw 8) and the like. Because there are multiple first material taking members 32, multiple flexible packaging materials can be grasped at the same time, or for a single flexible packaging material with a large area, more stable grasping can be achieved through multiple contact points.

[0060] The multiple first material taking members 32 are horizontally spaced along the cantilever 33, which makes it possible to cover a certain horizontal range when grasping the flexible packaging material. According to the size and shape of the flexible packaging material, the spacing distance between the first material taking members 32 can be adjusted to achieve the best grasping effect. For example, for long strip-shaped flexible packaging materials, the spacing of the first material taking members 32 can be set larger so that they can grasp along the length direction of the material, ensuring that the flexible packaging material is evenly stressed when being lifted and will not be damaged or deformed due to excessive stress on a single point.

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

[0062] First, improve the efficiency of grabbing: the design of multiple first material taking parts 32 can grab multiple flexible packaging materials at a time, greatly improving the efficiency of material taking compared to a single material taking part. Especially in the case of handling a large amount of flexible packaging materials, the number of material taking times can be reduced, thereby speeding up the workflow of the entire device.

[0063] Second, adapt to different sizes of materials: the horizontal spacing of the first material taking parts 32 along the cantilever 33 allows the mechanism to adapt to different sizes of flexible packaging materials. For smaller size materials, the spacing between the first material taking parts 32 can be adjusted to use fewer material taking parts for grabbing; for larger size materials, all material taking parts can participate in grabbing to ensure that the material can be firmly held. This flexibility allows the device to handle a variety of specifications of flexible packaging materials, improving the versatility of the device.

[0064] Referring to Figures 1 to 3 In some embodiments, the first material taking parts 32 are slidingly connected to the cantilever 33, and adjacent two first material taking parts 32 can move horizontally towards or away from each other along the cantilever 33.

[0065] In this embodiment, since the two adjacent first material taking parts 32 can move horizontally towards or away from each other along the cantilever 33, the spacing distance between the first material taking parts 32 can be flexibly adjusted. When it is necessary to grab a flexible packaging material of smaller size, the first material taking parts 32 can move towards each other to reduce the distance between them. In this way, the material taking parts can closely fit the size of the material, and only a part of the material taking parts or in a more appropriate distribution can be used to grab the material, avoiding the problem that the material taking parts cannot effectively grab the small size material due to the excessive distance between them.

[0066] For a flexible packaging material of larger size, the first material taking parts 32 move away from each other to increase the distance between them. In this way, the material taking parts can be distributed at appropriate positions on the material to ensure that they can grab the edges or key parts of the material. For example, for a flexible packaging material of larger width, the distance between the material taking parts can be adjusted so that they can grab both sides of the material, providing sufficient support and grabbing force to prevent the material from deforming or being damaged due to uneven stress during lifting.

[0067] The first material taking parts 32 can be slidingly adjusted in position, which is beneficial to optimizing the distribution of grabbing force on the flexible packaging material. For materials with uneven texture or special gravity distribution, the positions of the material taking parts can be adjusted to reasonably distribute the grabbing force to various key parts of the material. For example, for some flexible packaging materials that are heavier on one side, more first material taking parts 32 can be distributed on the heavier side or the positions of the material taking parts on this side can be adjusted to provide more grabbing force, thereby ensuring that the material can remain horizontal when being lifted, avoiding tilting or falling. This is only an exemplary illustration.

[0068] Referring to Figures 1 to 3 In some embodiments, the horizontal movement driving assembly 51 proposed in the embodiments of the present application comprises:

[0069] The first horizontal movement driving member 511 is arranged on the mounting base 1, and the output end of the first horizontal movement driving member 511 is connected to the receiving plate 52, so as to drive the receiving plate 52 to move along the horizontal direction towards the first material taking member 32 and the bag opening mechanism 4.

[0070] In the embodiments, the first horizontal movement driving member 511 effectively realizes the movement of the receiving plate 52 in the horizontal direction, thereby completing the transfer of the flexible packaging material between the first material taking member 32 and the bag opening mechanism 4. This enables the flexible packaging material to be smoothly transported from the material taking position to the bag opening position, so that the working process of the entire device can be performed in a coherent manner.

[0071] Before the device is started, the receiving plate 52 is in an initial position, and the first horizontal movement driving member 511 is in a standby state, and the entire device waits to perform the processing work of the flexible packaging material. At this time, the flexible packaging material has been stacked in the material storage mechanism 2.

[0072] When the vertical driving member 31 of the first material taking 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 an instruction to the first horizontal movement driving member 511 to start working.

[0073] After receiving the instruction, the first horizontal movement driving member 511 starts to operate and drive the receiving plate 52 to start moving along the horizontal direction towards the position where the first material taking member 32 is located. The receiving plate 52 moves to the position directly below the first material taking member 32 or the corresponding transfer position, so as to receive the flexible packaging material grabbed by the first material taking member 32.

[0074] When the receiving plate 52 reaches the specified position and the first material taking member 32 places the flexible packaging material on the receiving plate 52, the first horizontal movement driving member 511 again receives the instruction sent by the control system and starts to drive the receiving plate 52 to move towards the direction where the bag opening mechanism 4 is located, so as to transport the flexible packaging material to the operating position of the bag opening mechanism 4, thereby preparing for the subsequent bag opening operation of the bag opening mechanism 4 on the flexible packaging material.

[0075] Referring to Figures 1 to 3 In some embodiments, the horizontal movement driving assembly 51 proposed in the embodiments of the present application further comprises:

[0076] The second horizontal movement driving member 512 is arranged on the output end of the first horizontal movement driving member 511, and the output end of the second horizontal movement driving member 512 is connected to the receiving plate 52, so as to drive the receiving plate 52 to move along the horizontal direction towards the first material taking member 32 and the bag opening mechanism 4.

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

[0078] When the first horizontal movement driving member 511 moves the material receiving plate 52 to the target area (close to the first material taking member 32 or the bag opening mechanism 4), the second horizontal movement driving member 512 starts to work, generates a horizontal driving force through its own driving mechanism, and further adjusts the position of the material receiving plate 52, so that the material receiving plate 52 can be more accurately docked with the first material taking member 32 or accurately sent to the operation position of the bag opening mechanism 4.

[0079] Referring to Figures 1 to 3 In some embodiments, the full-automatic bag opening device for flexible packaging material also includes a mounting frame slidingly connected to the mounting base 1, and the material receiving plate 52 is arranged in the mounting frame, and the material receiving plate 52 is provided with a clearance hole.

[0080] The second horizontal movement driving member 512 is arranged in the mounting frame, and the horizontal movement driving assembly 51 further includes a conveying belt 513 connected to the second horizontal movement driving member 512 in a transmission mode, the conveying belt 513 is arranged in the clearance hole, and the conveying belt 513 is exposed on the upper side of the material receiving plate 52.

[0081] In the embodiment, the mounting frame slidingly connected to the mounting base 1 is designed to provide a basic support structure for the horizontal movement of the material receiving plate 52, and can also make the material receiving plate 52 move flexibly on the mounting base 1. The sliding connection mode can be realized by using a guide rail and a sliding block structure or a linear slide rail. For example, a guide rail is arranged on the mounting base 1, and a sliding block matched with the guide rail is arranged at the bottom of the mounting frame. In this way, the mounting frame can stably slide horizontally along the guide rail, so as to drive the material receiving plate 52 to move in the horizontal direction, so as to meet the transfer requirement of the material between the first material taking member 32 and the bag opening mechanism 4. This is only an exemplary description.

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

[0083] The conveying belt 513 is arranged in the avoiding hole and exposed on the upper side of the receiving plate 52, mainly for realizing short distance transportation of the flexible packaging material on the receiving plate 52. When the second horizontal moving driving member 512 accurately positions the receiving plate 52 to the position of the intersection with the first material taking member 32 or the operating position of the bag opening mechanism 4, the conveying belt 513 can be moved by the driving of the second horizontal moving driving member 512 to drive the flexible packaging material to move relative to the receiving plate 52 to approach the bag opening mechanism 4.

[0084] In some embodiments, when the self-sealing bag such as the bone buckle bag needs to be opened, the bone buckle sensor 200 can be arranged as the detection device to guide the work of the second horizontal moving driving member 512 to indicate the transportation position of the flexible packaging material, for example, whether it is correctly transported to the bag opening mechanism 4. Further, the bag mouth sensor 300 can be arranged as the detection device of the bag mouth position to detect whether the bag mouth position is correctly between the upper and lower suction cups or whether the bag mouth is correctly opened, which is only exemplarily described herein.

[0085] Referring to Figures 1 to 3 In some embodiments, the material feeding mechanism 6 proposed in the embodiments of the present application comprises a material feeding driving assembly 61 arranged on the mounting base 1 and a material taking suction cup 62 arranged on the output end of the material feeding driving assembly 61. The material feeding driving assembly 61 is used to drive the material taking suction cup 62 to approach or move away from the flexible packaging material on the bearing plate 21, and the material taking suction cup 62 is used to adsorb the flexible packaging material.

[0086] In the embodiments, the material feeding driving assembly 61 is arranged on the mounting base 1, and the material taking suction cup 62 arranged on the output end of the material feeding driving assembly 61 can move in the vertical direction (the direction of approaching or moving away from the flexible packaging material on the bearing plate 21). The material taking suction cup 62 is based on the negative pressure adsorption principle to grab the flexible packaging material. When the material taking suction cup 62 contacts the surface of the flexible packaging material, the inside of the suction cup is connected with an external vacuum equipment (such as a vacuum pump) to form a negative pressure environment. Under the action of the external atmospheric pressure, the flexible packaging material is tightly adsorbed on the surface of the suction cup, so as to realize the grabbing of the material. This adsorption mode is a relatively gentle and effective grabbing mode for the flexible packaging material, which can avoid damaging the material.

[0087] When the flexible packaging material on the receiving plate 52 completes the bag opening operation, the material feeding driving assembly 61 receives the instruction of the control system to start working. 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 suction disc 62 contacts the surface of the flexible packaging material, the external vacuum device is started to form negative pressure inside the suction disc. Under the action of atmospheric pressure, the flexible packaging material is adsorbed on the suction disc. At this time, the material feeding driving assembly 61 maintains a certain pressure to ensure that the adsorption between the suction disc and the material is firm, preventing the material from falling off in the subsequent material feeding process.

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

[0090] Resetting stage: After the material feeding is completed, the material feeding driving assembly 61 drives the material suction disc 62 to return to the initial position, waits for the next material feeding instruction, and so on, realizing continuous material feeding operation.

[0091] The application realizes automatic driving and adsorption mode through the material feeding mechanism 6 with the above structure, can quickly and accurately take down the opened flexible packaging material on the material receiving plate 52 and place it to the designated position, greatly improving the efficiency of material feeding.

[0092] In some embodiments, the material feeding driving assembly 61 can be a multi-axis manipulator, or a material taking manipulator structure composed of X-axis, Y-axis, Z-axis three-axis or more axis modules, which is only exemplarily described here.

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

[0094] The upper suction disc 41 and the lower suction disc 42 are oppositely arranged along the vertical direction, and are used to adsorb the flexible packaging material.

[0095] The upper driving member 43 and the lower driving member 44, the output ends of the upper driving member 43 and the lower driving member 44 are connected to the upper suction disc 41 and the lower suction disc 42 respectively, and are used to drive the upper suction disc 41 and the lower suction disc 42 to move away from each other to open the bag opening of the flexible packaging material.

[0096] In this embodiment, the upper and lower suction cups 41 and 42 are used to grab the flexible packaging material based on the negative pressure adsorption principle. When the suction cups contact the surface of the packaging material, a negative pressure environment is formed inside the suction cups by connecting with 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 cups. The upper and lower suction cups 42 are oppositely arranged along 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 and lower driving members 43 and 44 are connected to the upper and lower suction cups 41 and 42, respectively, and can be cylinders, electric push rods, or ball screw motors, etc. capable of generating linear motion. When the driving members work, they will generate driving forces in opposite directions, causing the upper and lower suction cups 41 and 42 to move in opposite directions. In this way, the bag opening is pulled open by using the adsorption force between the suction cups and the packaging material, realizing the bag opening operation.

[0098] When the flexible packaging material is transported to the position of the bag opening mechanism 4 by the receiving plate 52, it is expected that the flexible packaging material will extend between the upper and lower suction cups 42. The upper and lower suction cups 41 and 42 will move downward and upward (or other suitable movement modes) under the instruction of the control system through the driving members connected thereto, so as to contact the upper and lower parts of the bag opening of the flexible packaging material. Then, the external vacuum device is started to form a negative pressure inside the upper and lower suction cups 42, so as to adsorb the upper and lower parts of the bag opening of the packaging material on the upper and lower suction cups 42, respectively. After the bag opening is adsorbed firmly, the upper and lower driving members 43 and 44 of the bag opening driving 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, so as to gradually pull the bag opening apart by the driving forces in opposite directions.

[0099] When the bag opening is pulled open to a sufficient degree, the bag opening driving assembly stops working. At this time, the upper and lower suction cups 41 and 42 still adsorb the bag opening part, maintaining the opening state of the bag opening. Until other mechanisms (such as the filling mechanism, etc.) complete the corresponding operation or it is needed to transfer the opened bag, the suction cups will release the bag opening under the instruction of the control system.

[0100] In some embodiments, the bag opening can also be blown flat by the blowing bag mechanism 100 provided in the bag opening mechanism 100, so as to make the bag opening flat and facilitate adsorption. Figure 2

[0101] Referring to Figures 1 to 3 In some embodiments, the full-automatic bag opening device for flexible packaging material provided in the embodiments of the present application further comprises a bag clamping driving member 7, a clamping jaw 8, a bag pressing driving member 9, and a bag pressing member 10.

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

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

[0104] In the embodiment, when the material receiving plate 52 transports the flexible packaging material to the position of the bag opening mechanism 4, the upper suction disc 41 and the lower suction disc 42 first adsorb the upper and lower parts of the bag opening of the flexible packaging material in the manner described in the foregoing embodiment.

[0105] Firstly, the bag opening driving assembly (the upper driving member 43 and the lower driving member 44) starts to work, drives the upper suction disc 41 and the lower suction disc 42 to move away from each other, and pulls open the bag opening. In this process, the clamping jaw 8 keeps clamping the upper bag opening under the action of the bag clamping driving member 7, so as to ensure that the bag opening can be smoothly pulled open.

[0106] Secondly, the bag clamping driving member 7 starts to work, drives the clamping jaw 8 to move in the horizontal direction towards the bag opening. When the clamping jaw 8 reaches the appropriate position, it clamps the upper bag opening of the flexible packaging material. At this time, the clamping jaw 8 and the upper suction disc 41 can jointly act on the upper bag opening, so as to enhance the control strength on the upper bag opening, and make the bag opening more stable in the subsequent bag opening and operation process.

[0107] Then, the bag clamping driving member 7 drives the clamping jaw 8 clamping the upper bag opening to move away from the lower bag opening, so as to further open the upper and lower bag openings of the flexible packaging material. For example, this operation is usually used to further tear the bag opening of the flexible packaging material, so as to avoid the problem of bag opening adhesion or insufficient opening.

[0108] The application realizes the bag opening operation for the flexible packaging material with different materials and thicknesses through the above structure, and through the cooperative operation of various components, the state of the bag opening can be more accurately controlled, so as to improve the accuracy of the whole bag opening and subsequent operation.

[0109] In some embodiments, the bag clamping driving member 7 and the bag pressing driving member 9 can be driving members composed of multiple direction cylinders, such as vertical cylinders or horizontal cylinders, or rotating cylinders. Those skilled in the art can set according to actual needs.

[0110] The above merely provides part or preferred embodiments of the present application, and neither the text nor the drawings can limit the scope of protection of the present application. Any equivalent structure variations made according to the contents of the present application and drawings, or direct / indirect application in other related technical fields shall fall within the scope of protection of the present application.
