Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical communication modules, and particularly relates to a material bagging device and a bagging method. BACKGROUND

[0002] An optical communication module is a core component that is ubiquitous and essential in modern communication networks. Simply put, an optical communication module is an interface device that realizes photoelectric conversion. Its core function is: at the sending end: converts the electrical signal generated by the network device (such as a switch, router) into an optical signal, and transmits it over a long distance at a high rate through an optical fiber. At the receiving end: receives the optical signal from the optical fiber and converts it back into an electrical signal, which is delivered to the network device for processing.

[0003] As a high-precision device, the optical communication module needs to be packaged in an outer box during transportation and storage. With the deepening of Industry 4.0 and intelligent manufacturing, the outer box packaging machine of the optical communication module also pays more attention to the deep integration of intelligence and automation.

[0004] When using a packaging machine to package the outer box of the optical communication module, the material box and the material cover needed for packaging the outer box need to be alternately stacked and then loaded into the material bag at the bagging station. The existing technology mostly uses manual methods to open the material bag and place it at the bagging station. This method is inefficient, so there is an urgent need to design a device that can automatically feed the material bag to the bagging station and automatically open the material bag at the bagging station to facilitate the loading of the material box and the material cover into the material bag. SUMMARY

[0005] In view of the above deficiencies in the prior art, the technical problem to be solved by the present application is: how to provide a material bagging device and a bagging method that can automatically feed the material bag to the bagging station and automatically open the material bag at the bagging station to facilitate the loading of the material box and the material cover into the material bag.

[0006] To solve the above technical problems, the present application adopts the following solutions: A material bagging device, comprising: a bag loading mechanism, the bag loading mechanism comprising a bag loading module and a bag stacking module, a plurality of material bags being placed on the bag stacking module, and the bag loading module sequentially obtaining the material bags from the bag stacking module; a bagging mechanism, the bagging mechanism comprising a bag opening module and a stacking and conveying module, the stacking and conveying module being used to convey the material to the bag opening module, and the bag opening module being used to load the material into the material bag; a belt conveying mechanism, the bag loading module conveying the obtained material bag to the belt conveying mechanism, and the belt conveying mechanism being used to convey the material bag to the bag opening module.

[0007] Thus, the bagging device of the present application is used, first, the bag is placed on the bag stacking module, and the material (box and cover) is placed on the stack transmission module. Then the bag module obtains the bag from the bag stacking module in turn, and transports the obtained bag to the belt transmission mechanism. With the operation of the belt transmission mechanism, the bag is transported to the bag opening module. At the same time, the stack transmission module also transports the material to the bag opening module. The bag is opened at the bag opening module, and the material is transported into the bag by the bag opening module, thereby completing the bagging process. Therefore, the present application can automatically feed the bag to the bagging station and open the bag at the bagging station to facilitate the loading of the box and cover into the bag.

[0008] Preferably, the bag module includes a bag grabbing component, a bag axial linear motion component, and a bag vertical linear motion component. The bag axial linear motion component is used to drive the bag grabbing component to move linearly along the axial direction. The bag vertical linear motion component is used to drive the bag grabbing component to move linearly along the vertical direction. The bag grabbing component is driven by the bag axial linear motion component and the bag vertical linear motion component to grab the bag from the bag stacking module in turn and transport the bag to the belt transmission mechanism.

[0009] Thus, when the bag module sucks the bag from the bag stacking module, first, the bag axial linear motion component drives the bag grabbing component to move axially to the top of the bag stacking module. Then the bag vertical linear motion component drives the bag grabbing component to move vertically downward and grab the bag. After the grabbing is completed, the bag vertical linear motion component further drives the bag grabbing component to move vertically upward. When the bag grabbing component moves to a certain position, the bag axial linear motion component drives the bag grabbing component to move axially to a set position. Then the bag vertical linear motion component further drives the bag grabbing component to move vertically downward. When the bag grabbing component moves to a set position, the bag grabbing component places the bag on the belt transmission mechanism. The bag grabbing component is reset by the bag axial linear motion component and the bag vertical linear motion component, and waits for the next bag transportation.

[0010] Preferably, the bag grabbing component includes a bag grabbing mounting frame, a bag contact sensor, and a plurality of bag spring nozzles. The contact end of the bag contact sensor faces the direction of the bag. The plurality of bag spring nozzles are divided into two groups and arranged on both sides of the bag grabbing mounting frame. The bag spring nozzles in the same group are arranged in sequence along the length direction of the side of the bag grabbing mounting frame.

[0011] Thus, by setting the bag contact sensor and the bag spring suction nozzle on the bag grabbing mounting frame, when the bag grabbing component is driven by the bag vertical linear motion component to move vertically downward to a certain position, at this time the bag spring suction nozzle contacts the bag and generates a certain pre-pressing, the bag contact sensor is triggered, indicating that the bag has been reliably sucked, and then the bag grabbing component is driven by the bag vertical linear motion component to move vertically upward, thereby ensuring the reliability of the bag sucking.

[0012] Preferably, the length of the contact end of the bag contact sensor extending out of the bag grabbing mounting frame is less than the length of the corresponding side of the bag spring suction nozzle extending out of the bag grabbing mounting frame in a free state, so that the bag spring suction nozzle preferentially contacts the bag with the contact end of the bag contact sensor.

[0013] Thus, the bag spring suction nozzle preferentially contacts the bag with the contact end of the bag contact sensor, so that the bag contact sensor is triggered only after the bag spring suction nozzle has a certain suction force with the bag, ensuring that the bag spring suction nozzle has sufficient suction force on the bag, and further improving the reliability of the bag sucking.

[0014] Preferably, the upper bag module further comprises a pressing assembly, the pressing assembly comprising a pressing driving member and a pressing wheel, the fixed end of the pressing driving member being connected with the bag grabbing mounting frame, the power output end of the pressing driving member being connected with a pressing plate to drive the pressing plate to move vertically through the power output end of the pressing driving member, the pressing wheel being installed on the pressing plate to enable the pressing plate to drive the pressing wheel to move vertically and press the bag on the belt conveying mechanism.

[0015] Thus, since the size of the bag is generally large, if the upper bag module places the bag entirely on the belt conveying mechanism, the size of the entire packaging machine will undoubtedly be increased, so the upper bag module of the present scheme only places the bag partially on the belt conveying mechanism, and the pressing assembly is provided to ensure that the entire bag is completely and reliably conveyed onto the belt conveying mechanism. Specifically, when the bag spring suction nozzle places a part of the bag on the belt conveying mechanism, the vacuum of the bag spring suction nozzle is cancelled, the bag spring suction nozzle is separated from the bag by a certain distance, and then the power output end of the pressing driving member moves vertically downward, at this time the pressing plate and the pressing wheel move vertically downward following the power output end of the pressing driving member, the pressing wheel moves vertically downward to press the bag onto the belt conveying mechanism, and as the belt conveying mechanism operates, the bag is gradually completely conveyed onto the belt conveying mechanism, and the pressing wheel can ensure the stability of the bag transmission during the entire process.

[0016] Preferably, the pressing driving member is connected to the bag grabbing mounting frame through a pressing mounting plate, a pressing spring is arranged between the pressing mounting plate and the pressing plate, two ends of the pressing spring are connected to the pressing mounting plate and the pressing plate respectively, a pressing signal block is arranged on the pressing plate, a pressing sensor is arranged on the pressing mounting plate, and the contact end of the pressing signal block and the pressing sensor can be in contact or separated.

[0017] In this way, the pressing mounting plate is connected to the bag grabbing mounting frame, when the bag spring suction nozzle places a part of the bag on the belt conveying mechanism, the bag vertical linear motion component drives the bag grabbing mounting frame to move upward vertically, since the pressing sensor is connected to the pressing mounting plate and the pressing signal block is connected to the pressing plate, the pressing sensor moves upward with the pressing mounting plate, while the pressing signal block remains stationary, until the contact end of the pressing sensor and the pressing signal block are separated, the pressing sensor is triggered, at this time, the bag spring suction nozzle is separated from the bag, the bag vertical linear motion component stops driving the bag grabbing mounting frame to move upward, at the same time, the power output end of the pressing driving member moves downward vertically, the pressing plate and the pressing wheel move downward vertically with the power output end of the pressing driving member, the pressing wheel moves downward vertically to press the bag on the belt conveying mechanism.

[0018] Preferably, the stack conveying module comprises a material placing plate and a material longitudinal linear motion component, the material placing plate is used for placing materials, and the material longitudinal linear motion component is used for driving the material placing plate to move longitudinally.

[0019] In this way, the materials are placed on the material placing plate, and then the material placing plate is driven by the material longitudinal linear motion component to move longitudinally, so that the materials are conveyed to the bag opening module for bagging treatment.

[0020] Preferably, the material placing plate is further provided with a material positioning block and a material clamping driving member, the material positioning block and the material clamping driving member are used for placing materials, one side of the materials abuts against the material positioning block, the other side of the materials has a gap with the material clamping driving member, and the power output end of the material clamping driving member can move to the direction of the materials and abut against the materials in the corresponding position.

[0021] In this way, by arranging the material positioning block and the material clamping driving member, when the lowermost materials are placed on the material placing plate, in order to ensure the accuracy of the material position, the power output end of the material clamping driving member moves to the direction of the materials and exerts a force on the materials, so that the two ends of the materials abut against the material positioning block and the power output end of the material clamping driving member respectively, thereby ensuring the accuracy of the material placement position by limiting the two ends of the materials.

[0022] Preferably, the bag opening module includes a bag opening component, a material separation component, and a material conveying component. The bag opening component is used to open the bag conveyed by the belt conveyor mechanism. The material separation component is used to separate the material conveyed by the stacking conveyor module from the stacking conveyor module. The material conveying component is used to convey the separated material into the opened bag.

[0023] In this way, when the bag opening module is bagging materials, the material separation component first separates the material conveyed by the stacking and conveying module from the stacking and conveying module. Then, the material conveying component conveys the material to the corresponding position of the bag opening component. The bag opening component opens the bag conveyed by the belt conveyor mechanism. Then, the material conveying component continues to convey the material into the opened bag, thus completing the bagging process.

[0024] In addition, the present invention also provides a bagging method for the material bagging device described above, comprising: Multiple bags are placed on the stacking module, and the bag loading module sequentially picks up the bags from the stacking module and conveys them to the belt conveyor mechanism. The belt conveyor mechanism transports the bag to the bag opening module; The stacking and conveying module transports the material to the bag opening module, which then loads the material into the bag.

[0029] Furthermore, in describing representative embodiments, the specification can have presented the method and / or process as a particular sequence of steps. However, to the extent that the method or process depends on the particular order of steps, the method or process should not be limited to the

[0030] First, the material bagging device is provided in the embodiments of the present application, as shown in the accompanying drawings Figure 1 The material bagging device is arranged on the rack 5 of the packaging machine, and comprises a bag feeding mechanism 1, a bagging mechanism and a belt conveying mechanism 4. The bag feeding mechanism 1 comprises a bag feeding module and a bag stacking module, and a plurality of bags are placed on the bag stacking module, and the bag feeding module obtains the bags from the bag stacking module one by one. The bagging mechanism comprises a bag opening module 3 and a stack conveying module 2, the stack conveying module 2 is used for conveying the material to the bag opening module 3, and the bag opening module 3 is used for filling the material into the bag. The bag feeding module conveys the obtained bag to the belt conveying mechanism 4, and the belt conveying mechanism 4 is used for conveying the bag to the bag opening module 3.

[0031] In the present scheme, the running direction of the belt conveying mechanism 4 is the axial direction.

[0032] In this way, when the material bagging device of the present application is used, the bags are placed on the bag stacking module, and the material (the box and the cover) is placed on the stack conveying module 2. Then the bag feeding module obtains the bags from the bag stacking module one by one, and conveys the obtained bags to the belt conveying mechanism 4. With the running of the belt conveying mechanism 4, the bags are conveyed to the bag opening module 3, and at the same time, the stack conveying module 2 also conveys the material to the bag opening module 3. The bag is opened at the bag opening module 3, and the material is conveyed into the bag by the bag opening module 3, thereby completing the bagging process. Therefore, the present scheme can automatically feed the bags to the bagging station and open the bags at the bagging station to facilitate the filling of the box and the cover into the bag.

[0033] Next, each mechanism will be described in detail in combination with the accompanying drawings: Specifically, as shown in the accompanying drawings Figure 2 and the accompanying drawings Figure 3As shown, the upper bag mechanism 1 includes an upper bag module and a bag stacking module, the bag stacking module includes a bag placing plate 101, a plurality of bag positioning and adjusting plates 103 are arranged on the bag placing plate 101, the bag positioning and adjusting plates 103 are used to position the position of the bag, and a bag placing detection sensor 102 is also arranged at the middle position of the bag placing plate 101, which is used to detect the bag on the bag placing plate 101.

[0034] For example, as shown in the accompanying drawings Figure 3 As shown, the upper bag module includes a bag grabbing component, a bag axial linear motion component and a bag vertical linear motion component, the bag axial linear motion component is used to drive the bag grabbing component to move linearly in the axial direction, the bag vertical linear motion component is used to drive the bag grabbing component to move linearly in the vertical direction, and the bag grabbing component is sequentially grabbed from the bag stacking module under the driving of the bag axial linear motion component and the bag vertical linear motion component, and then the bag is transported to the belt conveying mechanism 4. Among them, the bag axial linear motion component and the bag vertical linear motion component respectively realize linear motion in the axial direction and the vertical direction. The linear motion can be realized in the form of a linear motor plus a linear guide rail, or in the form of a cylinder, a slider plus a guide rail, etc. These linear motion structures are all prior art. For those skilled in the art, the specific structure can be selected according to the actual design needs, and the implementation form of the linear structure does not bring substantial influence to the scheme of the present application, and does not belong to the technical scheme to be protected by the present application. Therefore, it will not be discussed in detail in the present application.

[0035] Specifically, the bag grabbing component includes a bag grabbing mounting frame 104, a bag contact sensor 107 and a plurality of bag spring nozzles 105 are installed on the bag grabbing mounting frame 104, the contact end of the bag contact sensor 107 faces the direction of the bag, the plurality of bag spring nozzles 105 are divided into two groups and arranged on the two sides of the bag grabbing mounting frame 104 respectively, the plurality of bag spring nozzles 105 in the same group are arranged in sequence along the length direction of the side of the bag grabbing mounting frame 104, and the length of the contact end of the bag contact sensor 107 extending out of the bag grabbing mounting frame 104 is less than the length of the corresponding side of the bag spring nozzle 105 extending out of the bag grabbing mounting frame 104 in the free state, so that the bag spring nozzle 105 is in contact with the bag 106 in priority to the contact end of the bag contact sensor 107.

[0036] Specifically, as shown in the accompanying drawings Figure 4As shown, the upper bag module further comprises a compression assembly, the compression assembly comprises a compression driving element 110 and a compression wheel 108, in the specific embodiment, the compression driving element 110 is a pneumatic cylinder, the compression wheel 108 has two, the compression driving element 110 is connected to the bag grabbing mounting frame 104 through a compression mounting plate 111, a compression sensor 109 is arranged on the compression mounting plate 111, the power output end of the compression driving element 110 is connected with a compression plate 113, so as to drive the compression plate 113 to move vertically through the power output end of the compression driving element 110, a compression spring 112 is further arranged between the compression mounting plate 111 and the compression plate 113, the two ends of the compression spring 112 are connected with the compression mounting plate 111 and the compression plate 113 respectively, a compression signal block 114 is further arranged on the compression plate 113, the contact end of the compression signal block 114 and the compression sensor 109 can be in contact or separated; the compression wheel 108 is mounted on the compression plate 113, so that the compression plate 113 can drive the compression wheel 108 to move vertically and compress the bag on the belt conveying mechanism 4.

[0037] The working process of the upper bag mechanism 1 is as follows: the bag 106 is placed on the bag stacking module, the bag is taken from the bag stacking module by the upper bag module in turn, and then the bag is conveyed to the belt conveying mechanism 4. When the bag is taken from the bag stacking module by the upper bag module, first, the bag grabbing component is driven by the bag axial linear motion component to move axially to the upper side of the bag stacking module, then the bag grabbing component is driven by the bag vertical linear motion component to move vertically downward and grab the bag, when the bag grabbing component moves vertically downward to a certain position, the bag contact sensor 107 is triggered, indicating that the bag has been reliably taken, and the specific use is that the contact end of the bag contact sensor 107 is triggered after the contact end of the bag spring suction nozzle 105 is in contact with the bag, so that the bag spring suction nozzle 105 has a certain suction force with the bag, ensuring that the bag spring suction nozzle 105 has sufficient suction force on the bag, further improving the reliability of the bag taking. After the bag is taken, the bag grabbing component is driven by the bag vertical linear motion component to move vertically upward, and when it moves upward to a certain position, the bag grabbing component is driven by the bag axial linear motion component to move axially to a set position, and then the bag grabbing component is driven by the bag vertical linear motion component to move vertically downward to a set position, and then the bag grabbing component is placed on the belt conveying mechanism 4, and the bag grabbing component is reset by the bag axial linear motion component and the bag vertical linear motion component, waiting for the next bag conveying.

[0038] Because the size of the bag is generally large, if the bag placing module places the bag on the belt conveying mechanism 4 entirely, the size of the whole packaging machine will undoubtedly be increased. Therefore, the bag placing module of the present application only places the bag on the belt conveying mechanism 4 partially, and the complete and reliable conveying of the bag to the belt conveying mechanism 4 is ensured by setting the pressing assembly. Specifically, when the bag spring suction nozzle 105 places a part of the bag on the belt conveying mechanism 4, the vacuum of the bag spring suction nozzle 105 is cancelled, and after the bag spring suction nozzle 105 is separated from the bag by a certain distance, the power output end of the pressing driving element 110 moves downward along the vertical direction. At this time, the pressing plate 113 and the pressing wheel 108 move downward along the vertical direction following the power output end of the pressing driving element 110, and the pressing wheel 108 moves downward along the vertical direction to press the bag onto the belt conveying mechanism 4. With the operation of the belt conveying mechanism 4, the bag is gradually conveyed onto the belt conveying mechanism 4 completely, and the stability of the bag conveying during the whole process is ensured by the pressing wheel 108. This is because the pressing mounting plate 111 is connected with the bag grabbing mounting frame 104 together. When the bag spring suction nozzle 105 places a part of the bag on the belt conveying mechanism 4, the bag vertical linear motion component will drive the bag grabbing mounting frame 104 to move upward along the vertical direction. Since the pressing sensor 109 is connected with the pressing mounting plate 111, and the pressing signal block 114 is connected with the pressing plate 113, the pressing sensor 109 will move upward following the pressing mounting plate 111, and the pressing signal block 114 remains stationary until the contact end of the pressing sensor 109 and the pressing signal block 114 are separated. The pressing sensor 109 is triggered at this time. The bag spring suction nozzle 105 is separated from the bag, and the bag vertical linear motion component stops driving the bag grabbing mounting frame 104 to move upward. At the same time, the power output end of the pressing driving element 110 moves downward along the vertical direction, and the pressing plate 113 and the pressing wheel 108 move downward along the vertical direction following the power output end of the pressing driving element 110. The pressing wheel 108 moves downward along the vertical direction to press the bag onto the belt conveying mechanism 4.

[0039] In the specific embodiment, as shown in the accompanying drawings Figure 5As shown, the stack conveying module comprises a material placing plate 202 and a material longitudinal linear motion assembly 201. The material placing plate 202 is used for placing the material 205, and the material longitudinal linear motion assembly 201 is used for moving the material placing plate 202 in the longitudinal direction. The material placing plate 202 is further provided with a material positioning block 203 and a material clamping driving element 204. The material positioning block 203 and the material clamping driving element 204 are used for placing the material. One side of the material abuts against the material positioning block 203, and the other side of the material has a gap with the material clamping driving element 204. The power output end of the material clamping driving element 204 can move in the direction of the material and abut against the material in the corresponding position. The material longitudinal linear motion assembly 201 realizes linear motion in the longitudinal direction. The linear motion can be realized by using a linear motor plus a linear guide structure, or a cylinder plus a slider plus a guide structure. These linear motion structures are all prior art. Those skilled in the art can select the specific structure according to the actual design needs. The linear structure does not have a substantial impact on the scheme of the present application, and does not belong to the technical scheme to be protected by the present application. Therefore, the linear structure is not discussed in detail in the present application.

[0040] The working method of the stack conveying module 2 is as follows: the material is placed on the material placing plate 202, and then the material placing plate 202 is moved in the longitudinal direction by the material longitudinal linear motion assembly 201, so as to convey the material to the bag opening module 3 for bagging processing. By arranging the material positioning block 203 and the material clamping driving element 204, when the lowermost material is placed on the material placing plate 202, in order to ensure the accuracy of the material position, the power output end of the material clamping driving element 204 moves in the direction of the material and applies a force to the material, so that the two ends of the material abut against the material positioning block 203 and the power output end of the material clamping driving element 204 respectively. Thus, the accuracy of the material placing position is ensured by limiting the two ends of the material.

[0041] In the specific embodiment, as shown in FIG. 2, the bag opening module 3 comprises a bag opening plate 301 and a bag opening driving element 302. The bag opening plate 301 is used for placing the bag 206, and the bag opening driving element 302 is used for moving the bag opening plate 301 in the longitudinal direction. The bag opening plate 301 is further provided with a bag positioning block 303 and a bag clamping driving element 304. The bag positioning block 303 and the bag clamping driving element 304 are used for placing the bag 206. One side of the bag 206 abuts against the bag positioning block 303, and the other side of the bag 206 has a gap with the bag clamping driving element 304. The power output end of the bag clamping driving element 304 can move in the direction of the bag 206 and abut against the bag 206 in the corresponding position. Figure 6 to FIG. 3, the bag opening module 3 comprises a bag opening plate 301 and a bag opening driving element 302. The bag opening plate 301 is used for placing the bag 206, and the bag opening driving element 302 is used for moving the bag opening plate 301 in the longitudinal direction. The bag opening plate 301 is further provided with a bag positioning block 303 and a bag clamping driving element 304. The bag positioning block 303 and the bag clamping driving element 304 are used for placing the bag 206. One side of the bag 206 abuts against the bag positioning block 303, and the other side of the bag 206 has a gap with the bag clamping driving element 304. The power output end of the bag clamping driving element 304 can move in the direction of the bag 206 and abut against the bag 206 in the corresponding position. Figure 8As shown, the bag opening module 3 comprises a bag opening assembly, a material separation assembly, a material conveying assembly and a bag opening longitudinal linear motion assembly 307. The bag opening assembly is used to open the bag conveyed by the belt conveying mechanism 4. The material separation assembly is used to separate the material conveyed by the stack conveying module 2 from the stack conveying module 2. The material conveying assembly is used to convey the separated material into the opened bag. The fixed part of the bag opening longitudinal linear motion assembly 307 is installed on the rack 5. The moving part of the bag opening longitudinal linear motion assembly 307 is connected with the material separation assembly and the bag tensioning part, so that the moving part of the bag opening longitudinal linear motion assembly 307 can drive the material separation assembly and the bag tensioning part to move longitudinally. In this way, when the bag opening module 3 is used to fill the bag with material, the material separation assembly is used to separate the material conveyed by the stack conveying module 2 from the stack conveying module 2. Then, the material conveying assembly is used to convey the material to the position corresponding to the bag opening assembly. The bag opening assembly opens the bag conveyed by the belt conveying mechanism 4. Then, the material conveying assembly continues to convey the material into the opened bag, thereby completing the bag filling process.

[0042] In particular, when the bag is conveyed by the belt conveying mechanism 4 to the bag opening module 3, the bag tensioning part is first driven by the bag opening longitudinal linear motion assembly 307 to move longitudinally away from the belt conveying mechanism 4, thereby leaving space for the bag to be conveyed. When the bag is conveyed to the position, the bag tensioning part is driven by the bag opening longitudinal linear motion assembly 307 to move towards the belt conveying mechanism 4, and the bag is opened. The bag opening longitudinal linear motion assembly 307 realizes linear motion in the longitudinal direction. The linear motion can be realized by a linear motor and a linear guide, or a cylinder, a slider and a guide. These structures for realizing linear motion are all prior art. Those skilled in the art can select the specific structure according to the actual design needs. The realization of the linear structure does not substantially affect the scheme of the present application, and does not belong to the technical scheme to be protected by the present application. Therefore, it will not be discussed in detail in the present application.

[0043] Specifically, the materials on the material placing plate 202 protrude from the material placing plate 202 at both axial ends, and the material separating assembly includes two material separating components symmetrically arranged on both sides of the material longitudinal linear motion assembly 201.

When the material moves along the material longitudinal linear motion assembly 201, the longitudinal guide rod 302 can extend into the bottom of the corresponding position of the material. The power output end of the material separating driving member 301 is connected to the longitudinal guide plate 303 and the longitudinal guide rod 302 through a separating connecting member, so that the material separating driving member 301 can drive the longitudinal guide plate 303 and the longitudinal guide rod 302 to move vertically at the same time, and the axial distance between the two longitudinal guide plates 303 is adapted to the axial size of the material. In this embodiment, the material separating driving member 301 is a pneumatic cylinder. The material conveying assembly includes a material longitudinal conveying power member 304 and a material vertical power member 305. The fixed end of the material longitudinal conveying power member 304 is connected to the rack 5, the power output end of the material longitudinal conveying power member 304 is connected to the fixed end of the material vertical power member 305, and the power output end of the material vertical power member 305 can move vertically and abut against the material at the material separating assembly, so that the material longitudinal conveying power member 304 can drive the material to move longitudinally through the material vertical power member 305. In this embodiment, the material longitudinal conveying power member 304 is a long-stroke longitudinal pneumatic cylinder, and the material vertical power member 305 is a vertical pneumatic cylinder.

[0044] The bag opening assembly includes a vacuum suction nozzle component and a bag tensioning component.

The lower vacuum suction nozzles 309 are fixed on a suction nozzle mounting plate, and the upper vacuum suction nozzles 311 are fixed on the power output end of a suction nozzle driving member 310. The power output end of the suction nozzle driving member 310 can drive the upper vacuum suction nozzles 311 to move vertically and contact the bag. In this embodiment, the suction nozzle driving member 310 is a pneumatic cylinder. The bag tensioning component includes two bag tensioning members 306 arranged axially. The bag tensioning member 306 includes two bag tensioning rods arranged vertically and having a set spacing. A bag tensioning driving member 308 is arranged at each bag tensioning member 306. The power output end of the bag tensioning driving member 308 is connected to the bag tensioning member 306, so that the bag tensioning driving member 308 can drive the bag tensioning member 306 to move axially. In this embodiment, the bag tensioning driving member 308 is a pneumatic cylinder.

[0045] The working process of the bag opening module 3 is as follows: when the material moves along the longitudinal linear motion assembly to the longitudinal guide rod 302, the longitudinal guide rod 302 will extend into the bottom of the material protruding from the material placing plate 202, and when the material is conveyed to the position of the material separation driving member 301, the longitudinal guide rod 302 has covered the bottom of the material, at this time, the material separation driving member 301 is started, the power output end of the material separation driving member 301 drives the longitudinal guide rod 302 and the longitudinal guide plate 303 to move synchronously upward in the vertical direction, under the support of the longitudinal guide rod 302, the material moves upward together with the longitudinal guide rod 302 and is separated from the material placing plate 202, so as to convey the material from the stack transmission assembly to the bag opening assembly. After the material is separated from the stack transmission assembly by the support of the longitudinal guide rod 302, the power output end of the material vertical power member 305 moves downward in the vertical direction and contacts the material, and then the material longitudinal conveying power member 304 drives the material vertical power member 305 together with the material to move in the longitudinal direction to the belt transmission mechanism 4, in the conveying process, the longitudinal guide plate 303 guides the movement of the material to ensure that the material travels according to the predetermined route.

[0046] In addition, before the material bag is conveyed to the bag opening assembly, the bag opening longitudinal linear motion assembly 307 drives the material bag tensioning member to move in the longitudinal direction away from the belt transmission mechanism, when the material bag moves to the bag opening assembly together with the belt transmission mechanism 4, the opening part of the material bag will be located on the suction nozzle mounting plate, at the same time, the lower vacuum suction nozzle 309 on the suction nozzle mounting plate is located below the material bag, the upper vacuum suction nozzle 311 on the power output end of the suction nozzle driving member 310 is located above the material bag, the lower vacuum suction nozzle 309 located below the material bag is fixed and cannot move, and the lower vacuum suction nozzle 309 tightly sucks the lower part of the material bag, while the upper vacuum suction nozzle 311 above the material bag can move up and down under the action of the suction nozzle driving member 310, so that the upper vacuum suction nozzle 311 can pull the upper part of the material bag upward under the action of the suction nozzle driving member 310, thereby opening the material bag. After the material bag is opened by the vacuum suction nozzle member, the bag opening longitudinal linear motion assembly 307 drives the two material bag tensioning members 306 to insert into the opened material bag, and then the bag opening longitudinal linear motion assembly 307 drives the corresponding material bag tensioning members 306 to move in the axial direction away from each other, at the same time, since each material bag tensioning member 306 includes two material bag tensioning rods vertically distributed and having a set interval, the entire material bag is completely opened and has a certain height of opening in the vertical direction, so as to facilitate the material to enter the material bag. After the material bag is further opened by the material bag tensioning member, the material longitudinal conveying power member 304 pushes the material into the material bag through the material vertical power member 305, and the bagging process of the material is completed.

[0047] In addition, the application also provides a bagging method of the above-mentioned material bagging device, which comprises: placing a plurality of material bags on the bag stacking module, the bag taking module sequentially taking the material bags from the bag stacking module and conveying the material bags to the belt conveying mechanism 4; the belt conveying mechanism 4 conveying the material bags to the bag opening module 3; the material stacking and conveying module 2 conveying the material to the bag opening module 3, and the bag opening module 3 filling the material into the material bags.

[0048] Specifically, the complete bagging method of the material bagging device is as follows: the material bags of the optical communication module are placed on the material bag placing plate 101 of the bag stacking module, and the material box and the material cover are placed on the material placing plate 202 of the material stacking and conveying module 2. The material stacking and conveying module 2 moves along the longitudinal direction and conveys the material to the bag opening module 3. When the material on the material placing plate 202 moves along the material longitudinal linear motion assembly 201 to the longitudinal guide rod 302, the material separating assembly separates the material from the material stacking and conveying module 2. At this time, the power output end of the material vertical power member 305 moves downward along the vertical direction and contacts the material, and then the material longitudinal conveying power member 304 moves the material vertical power member 305 along the longitudinal direction to the direction close to the material bag together with the material. On the other hand, the bag taking module takes the material bags from the bag stacking module and conveys the material bags to the conveying belt of the belt conveying mechanism 4. Before the material bags are conveyed to the bag opening assembly, the bag opening longitudinal linear motion assembly 307 moves the bag tensioning member along the longitudinal direction away from the belt conveying mechanism. When the material bags move to the bag opening assembly along with the belt conveying mechanism 4, the vacuum suction nozzle member opens the material bags. After the material bags are opened by the vacuum suction nozzle member, the bag opening longitudinal linear motion assembly 307 inserts the two bag tensioning members 306 into the opened material bags, and then the bag tensioning driving member 308 moves the corresponding bag tensioning members 306 along the axial direction to the direction away from each other to open the material bags in the form of a certain height opening. At this time, the material longitudinal conveying power member 304 pushes the material into the material bags through the material vertical power member 305, and the bagging process of the material is completed, which facilitates the material to enter the material bags. After the material separating assembly separates the material from the material stacking and conveying assembly, the material stacking and conveying assembly is reset, and the bag opening module 3 performs the bagging process of the material. At this time, the material to be bagged next time can be placed on the material placing plate 202, and the bag taking module can also synchronously take the material bags needed next time from the bag stacking module, so as to realize the synchronous work of multiple stations and further improve the bag sealing efficiency of the packaging machine.

[0049] In addition, as shown in the accompanying drawings Figure 9The whole structure schematic diagram of the packaging machine with the material bagging device is shown, the whole packaging machine comprises the material bagging device, a material cover feeding mechanism 6, a material box feeding mechanism 7 and a bag sealing mechanism 8, the material bagging device, the material cover feeding mechanism 6, the material box feeding mechanism 7 and the bag sealing mechanism 8 are all arranged on the rack 5, wherein the material box feeding mechanism 6 is used for conveying the material box to the stacking and conveying module 2 of the material bagging device, the material cover feeding mechanism 7 is used for conveying the material cover to the stacking and conveying module 2 of the material bagging device, then the material box and the material cover are conveyed to the bag opening module 3 by the stacking and conveying module 2, and the process of loading the material cover into the material bag is completed at the bag opening module 3, the material bag loaded with the material cover is further conveyed to the bag sealing mechanism 7 for bag sealing treatment, thereby completing the whole packaging process.
