Description

Technical Field

[0001] This invention relates to the field of packaging technology, and more specifically, to an automated packaging device for multi-specification fire extinguisher finished products. Background Technology

[0002] Packing finished fire extinguishers is a crucial step in facilitating subsequent product transportation. Its purpose is to provide physical protection for the products through standardized packing procedures, ensuring the integrity of the finished fire extinguishers and accessories during transportation, storage, and handling, and preventing damage caused by collisions or compression. Simultaneously, it achieves orderly storage and integration of products, improving the efficiency of logistics and warehousing management, and ensuring that accessories are complete and placed in a standardized manner. During packing, operators will select appropriate packaging boxes according to the model and specifications of the fire extinguishers. For fire extinguishers with accessories (such as spray hoses), the accessories will be securely fixed inside the box to prevent them from falling out and being lost or damaged.

[0003] The current packing method involves two conveyor lines: one for transporting finished fire extinguishers and the other for transporting the boxes. During transport, the finished fire extinguishers are gripped and placed inside the boxes by a robotic arm. Accessories are then placed manually. After the accessories are placed, the boxes continue to be transported and sealed.

[0004] However, this method has significant drawbacks due to the need for manual placement of parts: on the one hand, manual operation is inefficient, which restricts the overall efficiency of the packing process; on the other hand, manual operation is prone to errors, resulting in the omission or misplacement of parts. During packing, parts often fold, overlap, and are squeezed together. If they are directly packaged, it will affect the sealing of the box lid. Therefore, staff still need to make repeated adjustments, which brings inconvenience to subsequent steps. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automated packing device for multi-specification fire extinguisher finished products.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated packaging device for multi-specification fire extinguishers, comprising a conveying component, a bottle feeding component disposed on one side of the conveying component, a pipe feeding component disposed on the other side of the conveying component, and a placement component installed inside the conveying component, wherein a support component is provided at the bottom of the placement component.

[0007] The conveying assembly includes a gantry frame and a support set inside the gantry frame. Two sets of auxiliary conveying mechanisms are installed on the top of the support. The placement assembly and the support assembly are both located above the auxiliary conveying mechanisms. A gripping mechanism is installed on the inner top wall of the gantry frame and on one side of the placement assembly.

[0008] The pipe feeding assembly includes a support frame disposed on one side of the gantry and a pipe feeding conveyor belt mechanism installed on the top of the support frame. The conveyor belt surface of the pipe feeding conveyor belt mechanism is equipped with multiple sets of pipe feeding clamps, and a flipping mechanism is installed on the side of the support frame near the auxiliary conveying mechanism.

[0009] The present invention is further configured such that: a first conveying mechanism for conveying packaging boxes is provided on one side of the gantry frame, a second conveying mechanism for conveying support assemblies is provided on the other side of the gantry frame, and a transfer conveying mechanism and a transition conveying mechanism are installed on the top of the support and between the two sets of auxiliary conveying mechanisms, with the transition conveying mechanism located in the middle of the transfer conveying mechanism.

[0010] The present invention is further configured such that: the transfer and conveying mechanism includes two lifting cylinders installed on the top of the support, each of the piston rod ends of the two lifting cylinders is equipped with a lifting plate, the top of the two lifting plates is equipped with two conveyor belt mechanisms, the transition conveying mechanism is located between the two conveyor belt mechanisms, and the conveying direction of the conveyor belt mechanism is staggered with the conveying direction of the transition conveying mechanism.

[0011] By adopting the above technical solution, the first conveying mechanism on one side of the gantry conveyor transports the packaging box to the auxiliary conveying mechanism. The transition conveying mechanism between the two sets of auxiliary conveying mechanisms acquires and carries the packaging box for packing operations. The conveying direction of the conveyor belt mechanism is intersected with that of the transition conveying mechanism. After packing is completed, the lifting cylinder lifts the lifting plate, so that the conveyor belt mechanism lifts the packaging box and transports it away from the gantry to the sealing station.

[0012] The present invention is further configured such that: the bottle feeding assembly includes a support leg disposed on one side of the gantry and a bottle feeding conveyor belt mechanism installed on the top of the support leg, and two guide plates are installed on the top of the bottle feeding conveyor belt mechanism.

[0013] By adopting the above technical solution, when the finished fire extinguisher is placed on top of the bottle conveyor belt mechanism, the bottle conveyor belt mechanism transports the finished fire extinguisher. Then, the gripping mechanism adsorbs and grabs the transported finished fire extinguisher and places it into the packaging box. In order to facilitate the gripping mechanism, the finished fire extinguisher is in an upright state during the transport process. Therefore, in order to prevent the finished fire extinguisher from tipping over, two guide plates are used for limiting and guiding.

[0014] The invention is further configured such that: the flipping mechanism includes two fixed plates mounted on the support frame near the auxiliary conveying mechanism and a rotating rod rotatably connected between the two fixed plates; a servo motor is mounted on one side of one of the fixed plates, the output end of the servo motor is connected to one end of the rotating rod; a U-shaped plate is connected to the outer wall of the rotating rod; two bearing plates are slidably connected to the top of the U-shaped plate; an electric gripper is mounted on the end of the two bearing plates away from the U-shaped plate; two symmetrical grooves are opened on the U-shaped plate, and sliders are slidably connected inside the two grooves; the two sliders are correspondingly arranged with the two bearing plates and are connected to the corresponding bearing plates; two adjusting cylinders are mounted on the top of the U-shaped plate, the two adjusting cylinders are correspondingly arranged with the two bearing plates, and the piston rod of the adjusting cylinder is connected to the corresponding bearing plate.

[0015] The invention is further configured such that: the placement assembly includes an electric linear module installed on the inner top wall of the gantry frame, the driving direction of the electric linear module is the same as the conveying direction of the conveyor belt mechanism, a scissor bar mechanism is slidably connected to the bottom of the electric linear module, a connecting plate is installed at the bottom of the scissor bar mechanism, a rotary cylinder is installed at the top of the connecting plate, the output end of the rotary cylinder passes through the connecting plate and is connected to the rotary plate, a connecting plate is provided at the bottom of the rotary plate, a connecting rod is connected between the rotary plate and the connecting plate, a forward and reverse motor is installed at the top of the connecting plate, both output ends of the forward and reverse motors are connected to lead screws, the thread directions of the two lead screws are opposite, and the outer side walls of the two lead screws are threadedly connected to connecting blocks, the bottom of the two connecting blocks are connected to movable frames, the movable frames are slidably connected to the top of the connecting plate, the bottom of each movable frame extends downward and is connected to an insert plate, the insert plate is adapted to the support assembly.

[0016] The present invention is further configured such that: the support assembly includes a top plate, the top plate is hollow, and the top plate has an opening on the side facing the insert plate, the insert plate is inserted into the interior of the top plate through the opening, and two placement rack mechanisms are provided at the bottom of the top plate, the two placement rack mechanisms being stacked.

[0017] The present invention is further configured such that: both of the placement rack mechanisms include I-shaped frames, and a vertical plate is connected to the middle of the opposite side of the two I-shaped frames, and pipe clamps for securing fire extinguishers are symmetrically installed on both sides of the vertical plate.

[0018] The present invention is further configured such that: a plug rod and a tube are provided between the two I-shaped frames, the plug rod is connected to one of the I-shaped frames, the tube is connected to the other I-shaped frame, and the plug rod and the tube are mutually positioned and inserted.

[0019] The present invention is further configured such that: each of the four corners of the I-shaped frame is connected to a pressure block, the pressure block extends between two I-shaped frames, and the interior of the I-shaped frame is connected to a reinforcing rib.

[0020] By adopting the above technical solutions, automated packaging of spray hoses and finished fire extinguishers is achieved. The hose delivery conveyor and hose clamps stably deliver the hoses, while the flipping mechanism precisely completes the clamping, transfer, and packaging. The hose clamps and upright plates of the support assembly position the fire extinguishers, preventing nozzle offset interference. Their adjustable gaps, combined with the flipping mechanism, allow for diagonal placement of the hoses, reducing bending and compression. Reinforcing ribs and pressure blocks ensure the hoses are neatly arranged. The placement component drives the rotation and displacement of the support assembly, eliminating the need for a separate angle adjustment mechanism or multiple conveyor lines, thus improving efficiency, eliminating omissions and misplacement problems caused by manual operation, and enhancing the equipment's versatility and production stability.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] (1) By setting up a pipe feeding assembly and a flipping mechanism, the automated packing of spray hose accessories is realized. The pipe feeding conveyor belt mechanism, together with multiple sets of equally spaced pipe feeding clamps, can continuously and stably transport the spray hose. The flipping mechanism drives the U-shaped plate to swing through a servo motor and controls the position of the electric gripper with an adjusting cylinder to complete the clamping, transfer and packing of the hose, which improves the packing efficiency, eliminates the problem of missing or misplaced accessories caused by manual placement, ensures smooth box sealing operation, and reduces subsequent adjustment procedures.

[0023] (2) By setting up a support assembly, the bracket and the upright plate of the support assembly are used to position the fire extinguisher. The nozzle is attached to the side wall of the upright plate, which avoids the problem of nozzle displacement when the traditional misaligned placement is used. At the same time, the rotating cylinder of the placement assembly is used to make the support assembly rotate, realize the angle adjustment and stable grip of the support assembly, ensure that the fire extinguisher is placed at the preset angle, eliminate the interference of the nozzle displacement of the fire extinguisher on the placement of the spray hose, solve the hidden danger of hose popping out, and ensure the smooth operation of subsequent sealing.

[0024] (3) The grabbing mechanism first grabs the finished fire extinguisher and places it horizontally inside the pipe clamp. The nozzle part of the finished fire extinguisher is attached to one side of the upright plate. After the pipe clamp on one side of the bracket assembly is filled, the bracket assembly rotates 180 degrees. The grabbing mechanism grabs the finished fire extinguisher again and places it. The angle at which the grabbing mechanism grabs the four finished fire extinguishers and the adjusted placement angle are the same. There is no need to set up a separate angle adjustment mechanism to adjust the nozzle position of the finished fire extinguisher or to use multiple conveyor lines to transport fire extinguishers with different nozzle positions. It has strong adaptability and can adapt to different specifications of products through a unified grabbing angle, which enhances the versatility and production stability of the equipment.

[0025] (4) By setting up two sets of placement rack mechanisms, the two sets of placement rack mechanisms are connected by the cooperation of the insertion rod and the insertion tube, and form an adjustable placement gap. The flipping mechanism puts the hose diagonally into the placement gap to reduce bending and squeezing. The reinforcing ribs and pressure blocks prevent the hose from sagging or being flattened, ensuring that the accessories are placed neatly. Attached Figure Description

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0046] Please see Figures 1-11 The present invention provides the following technical solutions:

[0047] Example 1, see Figure 1 An automated packaging device for multi-specification fire extinguishers includes a conveying assembly 1 for conveying the packaging boxes. The specific structure of the conveying assembly 1 is as follows:

[0048] See Figures 1-3The conveying assembly 1 includes a gantry frame 11 and a support 12 disposed inside the gantry frame 11. Two sets of auxiliary conveying mechanisms 14 are installed on the top of the support 12. A first conveying mechanism 13 for conveying packaging boxes is provided on one side of the gantry frame 11. Both the auxiliary conveying mechanism 14 and the first conveying mechanism 13 are roller conveying mechanisms. The packaging boxes are set according to the specifications of the finished fire extinguishers. The packaging boxes are conveyed to the top of the auxiliary conveying mechanism 14 by the first conveying mechanism 13. A transfer conveyor is installed on the top of the support 12 and between the two sets of auxiliary conveying mechanisms 14. The auxiliary conveyor 14 and the transition conveyor 15 are located in the middle of the transfer conveyor 15. The transition conveyor 17 is a roller conveyor. The roller of the transition conveyor 17 is a rubber roller. The rubber surface of the roller is used to offset the sliding force of the packaging box through friction, thereby achieving the purpose of stopping the packaging box. After the packaging box reaches the top of the auxiliary conveyor 14, the transition conveyor 17 picks up the packaging box, causing the packaging box to stop above the transition conveyor 17. The packaging box is used for the packing of fire extinguisher products at this position.

[0049] After the finished fire extinguishers are packed, the transfer and conveying mechanism 15 lifts the packaging box containing the finished fire extinguishers and guides it to the next sealing station for sealing. The specific structure of the transfer and conveying mechanism 15 is as follows:

[0050] See Figure 2 and Figure 3 The transfer and conveying mechanism 15 includes two lifting cylinders 151 installed on the top of the support 12. Lifting plates 152 are installed at the piston rod ends of the two lifting cylinders 151. Two conveyor belt mechanisms 153 are installed on the top of the two lifting plates 152. The transition conveying mechanism 17 is located between the two conveyor belt mechanisms 153, and the conveying direction of the conveyor belt mechanism 153 is staggered with the conveying direction of the transition conveying mechanism 17. After the fire extinguisher is packaged, the two lifting cylinders 151 lift the corresponding lifting plates 152, causing the two conveyor belt mechanisms 153 to lift the packaging box away from the transition conveying mechanism 17. Then the two conveyor belt mechanisms 153 start and drive the packaging box to be sent away from the gantry 11. The conveyor belt mechanism 153 is connected to the sealing station. When the packaging box is sent out from the conveyor belt mechanism 153, it enters the sealing station for the next sealing operation.

[0051] A bottle feeding assembly 2 is provided on one side of the conveying assembly 1. The bottle feeding assembly 2 is used to convey finished fire extinguishers. A gripping mechanism 4 is installed on the inner top wall of the gantry frame 11 and on the side where the assembly 5 is placed. The gripping mechanism 4 consists of a robotic arm and a suction cup. The robotic arm controls the movement of the suction cup, which can then adsorb and grip the finished fire extinguishers conveyed on the bottle feeding assembly 2. After the finished fire extinguishers are gripped, they are placed inside an empty packaging box.

[0052] See Figure 1 and Figure 7 The specific structure of the bottle delivery component 2 is as follows:

[0053] The bottle delivery assembly 2 includes a support leg 21 located on one side of the gantry frame 11 and a bottle delivery conveyor belt mechanism 22 installed on the top of the support leg 21. The bottle delivery conveyor belt mechanism 22 can be a rubber conveyor belt mechanism. When the finished fire extinguisher is placed on the top of the bottle delivery conveyor belt mechanism 22, the bottle delivery conveyor belt mechanism 22 delivers the finished fire extinguisher. Then, the gripping mechanism 4 adsorbs and grips the delivered finished fire extinguisher and places it into the packaging box.

[0054] To facilitate the gripping by the gripping mechanism 4, the finished fire extinguisher is in an upright position during transport. Therefore, to prevent the finished fire extinguisher from tipping over, two guide plates 23 are installed on the top of the bottle conveyor belt mechanism 22. The finished fire extinguisher is guided and limited during transport using the two guide plates 23.

[0055] After the finished fire extinguisher is placed inside the packaging box, the staff put the accessories (spray hose) inside the packaging box, then adjust the position of the accessories. Subsequently, the packaging box containing the finished fire extinguisher and accessories is sent to the sealing station by the conveyor belt mechanism 153 for sealing.

[0056] Example 2: The existing method has significant drawbacks due to the need for manual placement of parts. On the one hand, manual operation is inefficient, which restricts the overall efficiency of the packing process. On the other hand, manual operation is prone to errors, resulting in the omission or misplacement of parts. During packing, parts often fold, overlap, and are squeezed together. If they are directly packaged, it will affect the sealing of the box lid. Therefore, staff still need to make repeated adjustments, which brings inconvenience to subsequent steps.

[0057] See Figure 1 , Figures 8-10 Therefore, a tube feeding assembly 3 is provided on the side of the conveying assembly 1 away from the bottle feeding assembly 2. The tube feeding assembly 3 can automatically convey the accessories and grab them to the packaging box. The specific structure of the tube feeding assembly 3 is as follows:

[0058] See Figure 1 , Figures 8-10The pipe feeding assembly 3 includes a support frame 31 set on one side of the gantry frame 11 and a pipe feeding conveyor belt mechanism 32 installed on the top of the support frame 31. Multiple sets of pipe feeding clamps 33 are installed on the surface of the conveyor belt of the pipe feeding conveyor belt mechanism 32. A flipping mechanism 34 is installed on the side of the support frame 31 near the auxiliary conveying mechanism 14. One set of pipe feeding clamps 33 is used to clamp a spray hose, and multiple sets of pipe feeding clamps 33 are arranged at equal intervals. They are all driven to move synchronously by the pipe feeding conveyor belt mechanism 32. When one set of pipe feeding clamps 33 moves to the appropriate position of the flipping mechanism 34, the flipping mechanism 34 flips and clamps the spray hose on the set of pipe feeding clamps 33. Then it flips again to the position of the packaging box to feed the spray hose, which facilitates the packaging operation of the spray hose accessories.

[0059] See Figure 8 and Figure 9 The specific structure of the flipping mechanism 34 is as follows:

[0060] The flipping mechanism 34 includes two fixed plates 341 mounted on the support frame 31 near the auxiliary conveying mechanism 14, and a rotating rod 343 rotatably connected between the two fixed plates 341. A servo motor 342 is mounted on one side of one of the fixed plates 341. The output end of the servo motor 342 is connected to one end of the rotating rod 343. A U-shaped plate 344 is connected to the outer wall of the rotating rod 343. The servo motor 342 drives the rotating rod 343 to rotate, thereby causing the U-shaped plate 344 to swing. Two bearing plates 345 are slidably connected to the top of the U-shaped plate 344. An electric gripper 34 is mounted on the end of the two bearing plates 345 away from the U-shaped plate 344. 6. During the swinging process, the U-shaped plate 344 drives the two support plates 345 to swing, which in turn drives the electric gripper 346 to move. The electric gripper 346 is used to grip the spray hose. Two sliding grooves 347 are symmetrically opened on the U-shaped plate 344. The sliding sliders 348 are slidably connected inside the two sliding grooves 347. The two sliding sliders 348 are correspondingly set with the two support plates 345 and are connected to the corresponding support plates 345. Two adjusting cylinders 349 are installed on the top of the U-shaped plate 344. The two adjusting cylinders 349 are correspondingly set with the two support plates 345 and the piston rod of the adjusting cylinders 349 is connected to the corresponding support plate 345.

[0061] When the spray hose is transferred through the flipping mechanism 34, the U-shaped plate 344 and the carrier plate 345 are first controlled to swing, thereby adjusting the position of the electric gripper 346. The electric gripper 346 moves to the position of one of the sets of pipe feeding clamps 33. Then, the adjusting cylinder 349 pushes the carrier plate 345 to move. The carrier plate 345 drives the electric gripper 346 to move closer to the pipe feeding clamp 33. The electric gripper 346 is placed on the outside of the spray hose. Then, the electric gripper 346 clamps the spray hose, while the pipe feeding clamp 33 releases the spray hose. The U-shaped plate 344 flips again, and the electric gripper 346 takes the spray hose out of the pipe feeding clamp 33 and transfers it to the position of the packaging box. And by adjusting the cylinder 349, it extends again. The carrier plate 345 drives the electric gripper 346 and the spray hose to move closer to the packaging box. After the electric gripper 346 releases the clamp, the spray hose can be put into the packaging box, thus achieving the purpose of automatic packaging of the spray hose.

[0062] In Example 3, when existing fire extinguishers are placed inside the box, the nozzles of the two fire extinguishers are misaligned to ensure that they do not interfere with or collide with each other after placement. However, with this method, the nozzles are prone to misalignment. The spray hose is usually placed between the two fire extinguishers, and the length of the accessory may exceed the inner diameter of the box. If the nozzles are misaligned, it will interfere with the placement of the spray hose, and the spray hose will also pop out of the packaging box, affecting the subsequent sealing operation.

[0063] See Figure 1 , Figure 3 and Figure 4 To this end, a placement component 5 is installed on the inner top wall of the gantry frame 11. A support component 6 is provided at the bottom of the placement component 5. Both the placement component 5 and the support component 6 are located above the auxiliary conveying mechanism 14. The support component 6 is used to position the finished fire extinguisher, while the placement component 5 is used to drive the support component 6 to move, thereby facilitating the placement of the support component 6 into the packaging box. A second conveying mechanism 16 is provided on the side of the gantry frame 11 away from the first conveying mechanism 13. The second conveying mechanism 16 is used to transport the support component 6. When the packaging box and the support component 6 are being transported, the second conveying mechanism 16 is first used to move the support component 6 onto the auxiliary conveying mechanism 14. Then, the auxiliary conveying mechanism 14 and the transition conveying mechanism 17 are used to move the support component 6 below the placement component 5. After that, the support component 6 is lifted by the placement component 5. At this time, the support component 6 can be used for loading the finished fire extinguisher and accessories. At the same time, the first conveying mechanism 13 transports the packaging box and transfers it to the transition conveying mechanism 17. The packaging box is located below the support component 6, which facilitates the placement and packaging of the support component 6.

[0064] See Figure 1 , Figures 3-5 The specific structure of component 5 is as follows:

[0065] The placement component 5 includes an electric linear module 503 installed on the inner top wall of the gantry frame 11. The driving direction of the electric linear module 503 is the same as the conveying direction of the conveyor belt mechanism 153. A scissor bar mechanism 51 is slidably connected to the bottom of the electric linear module 503. A connecting plate 53 is installed at the bottom of the scissor bar mechanism 51. The electric linear module 503 can be a stepper motor, linear guide, lead screw, or slide module; no specific limitation is made here. The scissor bar mechanism 51 is driven to slide by the electric linear module 503. The scissor bar mechanism 51 is used to drive the connecting plate 53 to move in the height direction. A rotary cylinder 52 is installed on the top of the connecting plate 53. The output end of the rotary cylinder 52 passes through the connecting plate 53 and is connected to a rotating plate 54. A connecting plate 56 is provided at the bottom of the rotating plate 54. A connecting rod 55 is connected between the rotating plate 54 and the connecting plate 56. The rotary cylinder 52 is used to drive the rotating plate 54, the connecting plate 56, and the connecting rod. The 55 rotates synchronously, thereby adjusting the angle of the connecting plate 56. A forward and reverse motor 57 is installed on the top of the connecting plate 56. Both output ends of the forward and reverse motor 57 are connected to lead screws 59. The threads of the two lead screws 59 are opposite, and the outer walls of the two lead screws 59 are threaded to connecting blocks 58. The bottom of the two connecting blocks 58 is connected to a moving frame 501. The moving frame 501 is slidably connected to the top of the connecting plate 56. The bottom of each moving frame 501 extends downward and is connected to a plug plate 502. The forward and reverse motor 57 is used to drive the lead screws 59 to rotate in the forward or reverse direction. The two connecting blocks 58 move back and forth according to the rotation direction of the lead screws 59. The two connecting blocks 58 drive the corresponding moving frame 501 and plug plate 502 to move respectively. When the two moving frames 501 are close to each other, the plug plate 502 can be connected to the bracket assembly 6. When the two moving frames 501 are far apart, the bracket assembly 6 can be released.

[0066] Specifically, an elongated slot is provided on the top of the movable frame 501. One side of this slot is open. When the two movable frames 501 move and separate, the connecting rod 55 can slide into the interior of the slot, thus preventing the connecting rod 55 from obstructing the movement of the movable frame 501. The movable frame 501 is U-shaped when viewed from the side, and the connecting plate 56 is located inside the movable frame 501. In the initial state, it will not cause obstruction. When the movable frame 501 moves, the connecting plate 56 always moves within the movable frame 501. Therefore, the movable frame 501 will not interfere with the connecting plate 56 when it is in motion.

[0067] Specifically, when the support assembly 6 moves below the placement assembly 5, the connecting plate 53 is first moved downward by the scissor bar mechanism 51, causing all the components below the connecting plate 53 to move downward as a whole. The two moving frames 501 move to the sides of the support assembly 6. Then, by driving the two moving frames 501 to move closer to each other, the insert plate 502 is inserted into the interior of the support assembly 6. At this time, the support assembly 6 is grabbed. Subsequently, the scissor bar mechanism 51 retracts, and the moving frames 501 and the insert plate 502 work together to lift the support assembly 6 to a certain height. At this time, the packaging box can be transported.

[0068] At this time, the grabbing mechanism 4 grabs the finished fire extinguisher from the pipe feeding conveyor belt mechanism 32 and adjusts the placement angle, placing the finished fire extinguisher into the placement position inside the bracket assembly 6. Then, the rotating cylinder 52 drives the rotating plate 54 and the components below the rotating plate 54 to rotate synchronously, thereby adjusting the side orientation of the bracket assembly 6 so that the finished fire extinguisher can fill the placement position inside the bracket assembly 6. After the finished fire extinguisher is filled, the electric linear module 503 can drive the scissor lever mechanism 51 and the components below the scissor lever mechanism 51 to move horizontally towards the pipe feeding assembly 3. The bracket assembly 6 moves to the position of the flipping mechanism 34. The flipping mechanism 34 places the spray hose into the bracket assembly 6. After the spray hose is placed, the bracket assembly 6 is reset and driven by the scissor lever mechanism 51 to sink into the packaging box. Then, the fully loaded packaging box can be moved out by the conveyor belt mechanism 153.

[0069] See Figure 5 and Figure 6 The specific structure of the support assembly 6 is as follows:

[0070] The support assembly 6 includes a top plate 61, which is hollow and has an opening on the side facing the insert plate 502. The insert plate 502 is inserted into the top plate 61 through the opening. The top plate 61 is used to connect with the insert plate 502, facilitating the overall gripping and transfer of the support assembly 6. Two placement rack mechanisms 62 are provided at the bottom of the top plate 61, and the two placement rack mechanisms 62 are stacked. The placement rack mechanisms 62 are used to place and support the finished fire extinguisher and the spray hose.

[0071] See Figure 5 and Figure 6Both placement rack mechanisms 62 include I-beams 621. A vertical plate 622 is connected to the middle of the opposite side of each I-beam 621. Pipe clamps 623 for securing fire extinguishers are symmetrically installed on both sides of the vertical plate 622. The pipe clamps 623 support and place the finished fire extinguishers. The finished fire extinguishers on the same side of both placement rack mechanisms 62 are placed in the same direction. When a finished fire extinguisher is placed, one side of the pipe clamp 623 on the support assembly 6 faces the bottle delivery assembly 2. The gripping mechanism 4 first grabs the finished fire extinguisher... The fire extinguisher is grabbed and placed horizontally inside the clamp 623. The nozzle of the finished fire extinguisher is attached to one side of the upright plate 622. After the clamp 623 on one side of the bracket assembly 6 is filled, the bracket assembly 6 rotates 180 degrees. The grabbing mechanism 4 grabs the finished fire extinguisher again and places it. The angle at which the grabbing mechanism 4 grabs the four finished fire extinguishers and the adjusted placement angle are all the same, which is highly adaptable. There is no need to set up two conveyor lines for conveying finished fire extinguishers in different directions or to set up a separate mechanism for adjusting the angle of the finished fire extinguishers.

[0072] See Figure 5 and Figure 6 A rod 63 and a tube 64 are provided between two I-shaped frames 621. The rod 63 is connected to one of the I-shaped frames 621, and the tube 64 is connected to the other I-shaped frame 621. The rod 63 and the tube 64 are mutually limited and inserted. The two placement frame mechanisms 62 are connected by the rod 63 and the tube 64. The rod 63 can slide inside the tube 64. The outer wall of the rod 63 is provided with a protrusion, and the outer wall of the tube 64 is provided with a through groove. The protrusion can slide inside the through groove, which ensures that the rod 63 slides inside the tube 64 without relative rotation between the two.

[0073] When the bracket assembly 6 is lifted by the placement assembly 5, the lower placement frame mechanism 62 moves downward under the influence of gravity, causing the insertion rod 63 to slide inside the insertion tube 64. A placement gap is pulled out between the two placement frame mechanisms 62. After the fire extinguisher is loaded onto the two placement frame mechanisms 62, the bracket assembly 6 moves closer to the delivery pipe assembly 3. The flipping mechanism 34 grabs the spray hose and inserts the spray hose into this placement gap, thereby realizing the loading of the spray hose. Moreover, the top plate 61 on the top of the bracket assembly 6 is flat, so the spray hose will not pop out and affect the sealing of the box when the packaging box is sealed.

[0074] Because the length of the spray hose exceeds the length of the finished fire extinguisher bottle, in order to reduce the amount of bending during the filling process, the spray hose is first removed from the delivery clamp 33 using the flipping mechanism 34, and then flipped to the placement gap position between the two placement bracket mechanisms 62. Subsequently, the two adjusting cylinders 349 are activated and extend simultaneously, causing the electric gripper 346 to place the spray hose into the placement gap. At this time, one of the adjusting cylinders 349 stops extending, while the other adjusting cylinder 349 continues to extend, so that the spray hose is placed diagonally within the placement gap to reduce the amount of bending.

[0075] After the bracket assembly 6 is fully loaded, its bottom first sinks into the packaging box, and the insert plate 502 is pulled out from the top plate 61. The bracket assembly 6 then falls completely into the packaging box. At this time, the upper placement rack mechanism 62 continues to move downward under the influence of gravity, and the insert rod 63 slides into the interior of the insert tube 64. The placement gap between each placement rack mechanism 62 is reduced. In order to ensure that the spray hose is not flattened, the insert rod 63 is used for auxiliary support. At the same time, the inside of the I-shaped frame 621 is connected with a reinforcing rib 624, which is used to support the spray hose and prevent it from sagging. Moreover, a pressure block 625 is connected to each of the four corners of each I-shaped frame 621. The pressure block 625 extends between the two I-shaped frames 621, and the pressure blocks 625 at corresponding positions on the two I-shaped frames 621 fit together, thereby assisting in the support of the four corners of the two I-shaped frames 621. The supporting effect is the same as the auxiliary support effect of the insert rod 63 using its own length, thus preventing the spray hose from being flattened.

[0076] After the bracket assembly 6 is fully installed inside the packaging box, the packaging box is moved out by the conveyor belt mechanism 153 and transported to the sealing station to facilitate the next sealing operation.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
