[0006] The present invention is further configured as follows: the bag placing assembly includes a bag placing roller rotatably connected to the frame and two bag feeding rollers located below the bag placing roller, the bag feeding roller being driven to rotate by a first motor installed on the frame, and the frame being rotatably connected to a plurality of bag guide rollers located between the bag placing roller and the bag feeding rollers.

[0007] By adopting the above technical scheme, a packaging bag with sealed sides and a through middle is wrapped around the bag placing roller, and the packaging bag hangs down, which is convenient for layout in a limited production environment, and also enables the packaging bag to enter the bag cutting assembly more smoothly, thereby improving the bag feeding efficiency; the two bag feeding rollers are respectively against the two sides of the packaging bag, and the first motor drives the bag feeding rollers to rotate, and then the bag feeding rollers push the packaging bag downward for automatic transmission, which can control the packaging length of the strain, is suitable for bag filling operations of different specifications, and is suitable for mass production.

[0008] The present invention is further configured as follows: the bag cutting assembly comprises bag cutting cylinders symmetrically fixed to the frame, the output ends of the bag cutting cylinders are fixed with connecting plates, and the connecting plates are sequentially installed with heat sealing blocks and cutting knives from top to bottom.

[0009] By adopting the above technical solution, when the packaging bag enters between the two bag cutting cylinders, the output ends of the bag cutting cylinders on both sides extend out at the same time, driving the cutter to separate the packaging bag located between the bag cutting cylinders from the main bag body above, and at the same time heat-seal the bottom end of the main bag body above to prepare for the next cutting packaging bag. At this time, the packaging bag located between the two bag cutting cylinders and below them is in a state of opening at the upper end and sealing at the lower end, thereby realizing automatic cutting of the packaging bag and further improving packaging efficiency.

[0010] The present invention is further configured as follows: the bag-stretching assembly includes a U-shaped mounting platform, bag-stretching cylinders symmetrically fixed on both sides of the U-shaped mounting platform, a fixing plate fixed to the output end of the bag-stretching cylinder and a suction cup installed on the fixing plate; the bag-covering assembly includes a horizontal screw rod rotatably connected to the frame, a second motor installed on the frame for driving the horizontal screw rod to rotate, and a movable seat threadedly connected to the horizontal screw rod and sliding on the frame; the U-shaped mounting platform is fixed with a connecting shaft rotatably connected to the movable seat, and the connecting shaft is controlled to rotate by a steering assembly.

[0011] By adopting the above technical scheme, when the packaging bag enters between the two bag cutting cylinders, the main body of the packaging bag to be cut is located between the depressions of the U-shaped mounting platform, and the output ends of the two bag-supporting cylinders extend out at the same time, thereby driving the suction cups on both sides to respectively abut against the two sides of the packaging bag to clamp the packaging bag, and the bag cutting assembly cuts the packaging bag, and the suction cup is connected to the air pump through the air pipe. The air pump is started to generate negative pressure inside the suction cup, thereby causing the two sides of the packaging bag to be adsorbed on the suction cups on both sides respectively, and then the output ends of the two bag-supporting cylinders return to pull the two sides of the packaging bag through the suction cups to open the packaging bag mouth, thereby reducing dependence on manual labor and thus reducing labor costs; the second motor drives the horizontal screw rod to rotate, thereby driving the moving seat and the U-shaped mounting platform to move along the horizontal direction of the frame, and the steering assembly controls the U-shaped mounting platform to rotate 90° by controlling the connecting shaft to turn the packaging bag from a vertical state to a horizontal state, and then in the process of the moving seat driving the horizontal packaging bag to move, the packaging bag with an open end is placed on the outside of the feeding channel, and the overall bagging structure is more compact and more efficient.

[0012] The present invention is further configured as follows: the steering assembly includes a gear fixed to the connecting shaft, the frame is fixed with a steering rack located below the gear and meshing with the gear, and the steering rack is located between the bag cutting assembly and the feeding channel.

[0013] By adopting the above technical solution, when the moving seat drives the U-shaped mounting platform to move toward the feeding channel, the gear engages with the steering rack, the steering rack drives the gear to rotate and then drives the connecting shaft to rotate 90°, switching the bag body from a vertical state to a horizontal state, and then placing the bag body on the outside of the feeding channel.

[0014] The present invention is further configured as follows: arc-shaped support plates are provided on both sides of the bottom of the U-shaped mounting platform, the upper end of the arc-shaped support plate on the side close to the feeding channel is hinged to the U-shaped mounting platform and a unloading cylinder is hinged between the bottom of the U-shaped mounting platform, and the arc-shaped support plate on the other side is fixed to the U-shaped mounting platform.

[0015] By adopting the above technical scheme, when the bag body is placed on the outside of the feeding channel and the shiitake mushroom spawn in the storage box begins to be fed into the bag body, the horizontal screw rotates to drive the moving seat and the bag body to move away from the feeding channel, that is, the bag body is filled while moving outward, thereby realizing continuous filling, reducing pause time, maximizing the use of the space of the packaging bag, reducing excess gaps, and thus reducing material waste. The arc support plate supports the part of the packaging bag that is filled and moves out of the feeding channel, thereby improving the stability of the packaging work; when packaging is completed, the negative pressure in the suction cup is released to loosen the bag body, and the unloading cylinder is started to drive the lower arc support plate to flip and unload, thereby realizing automatic unloading and further improving packaging efficiency.

[0017] By adopting the above technical scheme, when the packaging bag is placed on the outside of the feeding channel, the arc-shaped support plate and the arc-shaped splint are also fitted to the packaging bag and located on the outside of the feeding channel. The rotation of the horizontal screw drives the suction cup, the arc-shaped support plate and the arc-shaped splint to move, and jointly promotes the stable horizontal movement of the bag body relative to the feeding channel, thereby improving the stability of continuous packaging; the bag body removed from the feeding channel has been filled with bacterial strains, and the arc-shaped splint stably supports the bag body under the push of the first spring, which is suitable for packaging of bacterial strains of different specifications, making the overall packaging structure more flexible and more applicable.

[0018] The present invention is further configured as follows: a conveying shaft extending into the feeding channel rotates in the storage box, a spiral conveying blade is fixed to the outer wall of the conveying shaft, and the conveying shaft is driven to rotate by a driving assembly.

[0019] By adopting the above technical solution, the driving component drives the conveying shaft to rotate, and then the conveying shaft conveys the shiitake mushroom spawn in the storage box from the feeding channel to the bag body arranged outside the feeding channel through the spiral conveying blades, which can effectively and evenly convey the spawn to the filling port of the feeding channel, ensuring that the amount of spawn in each bag body is consistent.

[0020] The present invention is further configured as follows: the driving assembly includes a fixed rod fixed to one side of the moving seat, a plurality of guide rods are inserted and slidably connected to the fixed rod, a ratchet bar is fixed between the ends of the guide rods, a second spring sleeved on the outside of the guide rods is fixed between the ratchet bar and the fixed rod, a ratchet wheel that cooperates with the ratchet bar is rotatable on the frame, a first bevel gear is coaxially fixed to the ratchet wheel, a transmission shaft is rotatable on the frame, a second bevel gear meshing with the first bevel gear is fixed to the transmission shaft, and a transmission belt is sleeved between the transmission shaft and the end of the conveying shaft extending out of the storage box.

[0021] By adopting the above technical scheme, when the bag body is placed outside the feeding channel, the horizontal screw starts to rotate to drive the movable seat and the bag body to move away from the feeding channel, and the ratchet bar cooperates with the ratchet wheel to drive the ratchet wheel to rotate, and then the first bevel gear coaxial with the ratchet wheel rotates synchronously, driving the second bevel gear to rotate, and then the conveying shaft is driven to rotate synchronously through the transmission shaft and the transmission belt, and the shiitake mushroom spawn in the storage box is sent from the feeding channel to the bag body placed outside the feeding channel through the spiral conveying blades, so that the bag body can be loaded while moving. When the bag body is moved out of the feeding channel, the ratchet bar no longer cooperates with the ratchet wheel, and the loading is stopped. The feeding amount in the feeding channel is controlled according to the specifications of the bag body, so that the overall packaging structure cooperates with each other and is more compact, further improving the flexibility of the device and the processing efficiency.

[0022] The present invention is further configured as follows: a conveyor belt is driven on the conveying platform, and a material receiving frame located below the feeding channel is evenly fixed on the conveyor belt along the conveying direction.

[0023] By adopting the above technical solution, when the bacteria in the bag are filled, the unloading cylinder starts to drive the arc-shaped support plate to flip and automatically unload, and the filled bag falls into the receiving frame below with the opening facing upward, and the conveyor belt continues to transport the bag forward for the next sealing work.

[0024] The beneficial effects of the present invention are:

[0025] 1. The packaging bags with sealed sides and a through middle are wrapped around the bag placing roller, and the packaging bags hang down, which is convenient for layout in a limited production environment. At the same time, it also makes the packaging bags enter the bag cutting assembly more smoothly, improving the bag feeding efficiency; the two bag feeding rollers are respectively against the two sides of the packaging bag, and the first motor drives the bag feeding roller to rotate, and then the bag feeding roller pushes the packaging bag downward to automatically convey it, which can control the length of the strain packaging, is suitable for bagging operations of different specifications, and is suitable for batch production;

[0026] 2. When the packaging bag enters between the two bag cutting cylinders, the output ends of the bag cutting cylinders on both sides extend out at the same time, driving the cutter to separate the packaging bag between the bag cutting cylinders from the upper main bag body, and heat-seal the bottom of the upper main bag body at the same time, preparing for the next cutting packaging bag. At this time, the packaging bag between the two bag cutting cylinders and below is in the state of opening at the upper end and sealing at the lower end, realizing automatic cutting of packaging bags and further improving packaging efficiency;

[0027] 3. The output ends of the two bag-supporting cylinders extend out at the same time, driving the suction cups on both sides to respectively contact the two sides of the packaging bag to clamp the packaging bag. The bag-cutting assembly cuts the packaging bag. The suction cups are connected to the air pump through the air pipe. The air pump is started to generate negative pressure inside the suction cups, so that the two sides of the packaging bag are respectively adsorbed on the suction cups on both sides. Then, the output ends of the two bag-supporting cylinders return to pull the two sides of the packaging bag through the suction cups to open the packaging bag mouth, reducing dependence on manual labor and thus reducing labor costs;

[0028] 4. When packaging is completed, the negative pressure in the suction cup is released to loosen the bag body, and the unloading cylinder starts to drive the lower arc-shaped support plate to flip and unload, realizing automatic unloading and further improving packaging efficiency;

[0029] 5. When the bag body is placed outside the feeding channel, the horizontal screw starts to rotate to drive the moving seat and the bag body to move away from the feeding channel. The ratchet bar cooperates with the ratchet wheel to drive the ratchet wheel to rotate, and then the first bevel gear coaxial with the ratchet wheel rotates synchronously, driving the second bevel gear to rotate, and then the conveying shaft is driven to rotate synchronously through the transmission shaft and the transmission belt. The shiitake mushroom spawn in the storage box is sent from the feeding channel to the bag body placed outside the feeding channel through the spiral conveying blades, so that the bag body can be loaded while moving, and the feeding amount in the feeding channel is controlled according to the specifications of the bag body, so that the overall packaging structure cooperates with each other and is more compact, further improving the flexibility of the device and the processing efficiency.

The bag feeding roller 42 is driven to rotate by a first motor installed on the frame 2. The frame 2 is rotatably connected to a plurality of bag guiding rollers 43 located between the bag placing roller 41 and the bag feeding roller 42. A packaging bag with sealed ends on both sides and a through middle is wrapped around the bag placing roller 41. The packaging bag hangs downward, and the two bag feeding rollers 42 respectively abut against both sides of the packaging bag. The first motor drives the bag feeding roller 42 to rotate, and then the bag feeding roller 42 pushes the packaging bag downward to automatically transport it, which can control the packaging length of the strain and is suitable for bag packing operations of different specifications.

The suction cups 64 are connected to the air pump through the air pipe. When the air pump is started, negative pressure is generated inside the suction cups 64, so that the two sides of the packaging bag are respectively adsorbed on the suction cups 64 on both sides. Then, the output ends of the two bag-supporting cylinders 62 return to pull the two sides of the packaging bag through the suction cups 64 to open the packaging bag mouth. The second motor 72 drives the horizontal screw rod 71 to rotate, thereby driving the moving seat 73 and the U-shaped mounting platform 61 to move horizontally along the frame 2. The steering assembly 8 controls the U-shaped mounting platform 61 to rotate 90° by controlling the connecting shaft 74 to turn the packaging bag from a vertical state to a horizontal state, and then the packaging bag with an open end is placed on the outside of the feeding channel 32 during the process of the moving seat 73 driving the horizontal packaging bag to move.
