Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and more particularly to an automatic packaging device for finished fire extinguishers of various specifications. Background Art

[0002] The packing of finished fire extinguishers is a key step in facilitating the transportation of subsequent products. Its purpose is to provide physical protection for the products through standardized packing operations to ensure the integrity of the finished fire extinguishers and accessories during transportation, warehousing, and handling, and to avoid damage caused by collision, extrusion, etc.; at the same time, it can achieve orderly storage and integration of products, improve the efficiency of logistics transportation and warehousing management, and ensure that the accessories are complete and placed in a standardized manner. When packing, the operator will select appropriate packaging boxes according to the model and specifications of the fire extinguisher. For fire extinguishers with accessories (such as spray hoses), the accessories will be properly fixed in the box to prevent the accessories from falling off and causing loss or damage.

[0003] The current packaging method involves two conveyor lines: one for transporting finished fire extinguishers and the other for transporting packaging boxes. During transport, the finished fire extinguishers are grabbed and transferred by a robotic arm and placed inside the boxes. Accessories are then manually placed. Once the accessories are placed, the boxes continue on to the conveyor and are sealed.

[0004] However, this method has significant disadvantages due to the need for manual placement of accessories: on the one hand, manual operation is inefficient, which restricts the efficiency of the overall packing process; on the other hand, manual operation is prone to errors, resulting in missing or misplaced accessories. During packing, accessories often fold, overlap and squeeze each other. Direct packaging will affect the sealing operation of the box lid. Therefore, staff still need to make repeated adjustments, which brings inconvenience to subsequent links. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide an automatic packing device for finished fire extinguishers of multiple specifications.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an automated packing device for finished fire extinguishers of multiple specifications, comprising a conveying assembly, a bottle delivery assembly arranged on one side of the conveying assembly, a pipe delivery assembly arranged on the other side of the conveying assembly, and a placement assembly installed inside the conveying assembly, wherein a bracket assembly is provided at the bottom of the placement assembly.

[0007] The conveying assembly includes a gantry and a support arranged inside the gantry. Two sets of auxiliary conveying mechanisms are installed on the top of the support.

[0011] By adopting the above technical solution, the first conveying mechanism on one side of the gantry conveys the package box to the auxiliary conveying mechanism, and the transition conveying mechanism between the two groups of auxiliary conveying mechanisms obtains and carries the package box for packing operations, and the conveying direction of the conveyor belt mechanism is staggered with that of the transition conveying mechanism; after the packing is completed, the lifting cylinder lifts the lifting plate, so that the conveyor belt mechanism lifts the package box and transports it away from the gantry to the sealing station.

[0012] The present invention is further configured as follows: the bottle feeding assembly includes a support leg arranged 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 the top of the bottle conveyor belt mechanism, the bottle conveyor belt mechanism transports the finished fire extinguisher, and then the conveyed finished fire extinguisher is adsorbed and grabbed by the grabbing mechanism and placed in the packaging box. In order to facilitate the grabbing of the grabbing mechanism, the finished fire extinguisher is in a standing state during the conveying process. Therefore, in order to prevent the finished fire extinguisher from tipping over, two guide plates are used for limiting guidance.

[0014] The present invention is further configured as follows: the flip mechanism includes two fixed plates installed on one side of the support frame close to the auxiliary conveying mechanism and a rotating rod rotatably connected between the two fixed plates, one side of one of the fixed plates is equipped with a servo motor, the output end of the servo motor is connected to one end of the rotating rod, the outer wall of the rotating rod is connected to a U-shaped plate, the top of the U-shaped plate is slidably connected to two supporting plates, and the two supporting plates are equipped with electric clamps at one end away from the U-shaped plate, two sliding grooves are symmetrically provided on the U-shaped plate, the inside of the two sliding grooves are slidably connected with sliders, the two sliders are arranged corresponding to the two supporting plates, the sliders are connected to the corresponding supporting plates, and two adjusting cylinders are installed on the top of the U-shaped plate, the two adjusting cylinders are arranged corresponding to the two supporting plates, and the piston rods of the adjusting cylinders are connected to the corresponding supporting plates.

[0015] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring, and castor is arranged on the pin of base bottom four, to carry mobile handler location.

[0016] The present invention is further configured as follows: the bracket assembly includes a top plate, the top plate is hollow, and an opening is provided on the side of the top plate facing the plug-in plate, the plug-in 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, and the two placement rack mechanisms are stacked.

[0017] The present invention is further configured as follows: the two placement rack mechanisms each include an I-shaped frame, a vertical plate is connected to the middle of one side of the two I-shaped frames that are opposite to each other, and pipe clamps for clamping the fire extinguisher are symmetrically installed on both sides of the vertical plate.

[0018] The present invention is further configured as follows: an insertion rod and an insertion tube are provided between the two I-shaped frames, the insertion rod is connected to one of the I-shaped frames, the insertion tube is connected to the other I-shaped frame, and the insertion rod and the insertion tube are mutually limitedly inserted.

[0019] The present invention is further configured as follows: four corners of each I-shaped frame are connected with a pressing block, the pressing block extends between two I-shaped frames, and the interior of the I-shaped frame is connected with a reinforcing rib.

[0020] By adopting the above technical solutions, the automatic packing of spray hoses and finished fire extinguishers is realized. The pipe conveyor belt mechanism and the pipe feeding clamp stably convey the hoses, and the flipping mechanism accurately completes the clamping, transfer and packing. The pipe clamp and the vertical plate of the bracket assembly position the fire extinguisher to avoid interference from nozzle offset. The adjustable gap cooperates with the flipping mechanism to realize diagonal placement of the hose, reducing bending and extrusion. The reinforcing ribs and pressure blocks ensure the regularity of the hose. The placement assembly drives the bracket assembly to rotate and move, without the need for a separate angle adjustment mechanism or multiple conveyor lines, which improves efficiency, eliminates the omissions and misplacement problems of manual operations, and enhances the versatility of the equipment and production stability.

[0021] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a tube feeding assembly and a flipping mechanism, the automatic packing of spray hose accessories is realized. The tube feeding conveyor belt mechanism cooperates with multiple sets of equidistantly arranged tube feeding clamps to 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 clamp by adjusting the cylinder to complete the clamping, transfer and packing of the hose, thereby improving the packing efficiency, eliminating the problems of missing and misplacing accessories caused by manual placement, ensuring the smooth sealing of the box cover, and reducing the subsequent adjustment process.

[0022] (2) By setting up a bracket assembly, the finished fire extinguisher is positioned by using the pipe clamp and the vertical plate of the bracket assembly, and the nozzle is fitted to the side wall of the vertical plate, avoiding the problem of easy displacement of the nozzle during traditional misplaced placement. At the same time, the rotating cylinder of the placement assembly is used to enable the bracket assembly to rotate, realizing the angle adjustment and stable grasping of the bracket assembly, ensuring that the fire extinguisher is placed at a preset angle, eliminating the interference of the nozzle displacement of the finished fire extinguisher on the placement of the spray hose, solving the hidden danger of the hose popping out, and ensuring the smoothness of the subsequent box sealing operation.

[0023] (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 fits on one side of the vertical plate. After the pipe clamp on one side of the bracket assembly is installed, the bracket assembly rotates 180 degrees as a whole. The grabbing mechanism grabs the finished fire extinguisher again and places it. The angles at which the grabbing mechanism grabs the four finished fire extinguishers and the adjusted placement angles 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 convey fire extinguishers with different nozzle positions. It has strong adaptability and can adapt to products of different specifications through a unified grabbing angle, thereby enhancing the versatility and production stability of the equipment.

[0024] (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 an adjustable placement gap is formed. The flipping mechanism places the hose diagonally into the placement gap to reduce bending and extrusion. The reinforcing ribs and pressure blocks prevent the hose from sagging or being flattened, ensuring that the accessories are placed neatly. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] 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 ordinary technicians in the technical field to which this application belongs.

[0039] See also Figures 1-11 , the present invention provides the following technical solutions: Example 1, see Figure 1 An automatic packing device for finished fire extinguishers of various specifications includes a conveying component 1 for conveying packaging boxes. The specific structure of the conveying component 1 is as follows: See Figure 1-Figure 3The conveying assembly 1 includes a gantry 11 and a support 12 arranged inside the gantry 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 11. The auxiliary conveying mechanism 14 and the first conveying mechanism 13 are both roller conveying mechanisms. The packaging boxes are arranged according to the specifications of the finished fire extinguisher. The packaging boxes are conveyed to the top of the auxiliary conveying mechanism 14 through 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 conveying mechanism 15 and the transition conveying mechanism 17 are located in the middle of the transfer conveying mechanism 15. The transition conveying mechanism 17 is a roller conveying mechanism. The roller of the transition conveying mechanism 17 is set as 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 the packaging box staying. After the packaging box reaches the top of the auxiliary conveying mechanism 14, the transition conveying mechanism 17 will obtain the packaging box, causing the packaging box to stay above the transition conveying mechanism 17. The packaging box is packed at this position for the finished fire extinguisher.

[0040] When the finished fire extinguishers are packed, the transfer conveyor mechanism 15 lifts the packaging box containing the finished fire extinguishers and guides it to the next box sealing station for box sealing. The specific structure of the transfer conveyor mechanism 15 is as follows: See Figure 2 and Figure 3 The transfer conveying mechanism 15 includes two lifting cylinders 151 installed on the top of the support 12, and the piston rod ends of the two lifting cylinders 151 are installed with lifting plates 152. 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. When the finished fire extinguishers are packed, the two lifting cylinders 151 lift the corresponding lifting plates 152, prompting the two conveyor belt mechanisms 153 to lift the packaging box, and the packaging box is away from the transition conveying mechanism 17. After that, the two conveyor belt mechanisms 153 are started and drive the packaging box to be sent away from the gantry 11. The conveyor belt mechanism 153 is connected to the box sealing station. When the packaging box is sent out from the conveyor belt mechanism 153, it enters the box sealing station for the next step of box sealing operation.

[0041] A bottle feeding assembly 2 is provided on one side of the conveying assembly 1, and the bottle feeding assembly 2 is used to transport the finished fire extinguishers. A grabbing mechanism 4 is installed on the inner top wall of the gantry 11 and on one side of the placement assembly 5. The grabbing mechanism 4 is composed of a manipulator and a suction cup. The manipulator controls the movement of the suction cup, and then can absorb and grab the finished fire extinguisher conveyed on the bottle feeding assembly 2. After the finished fire extinguisher is grabbed, it is placed inside an empty packaging box.

[0042] See Figure 1 and Figure 7 The specific structure of the bottle delivery component 2 is as follows: The bottle feeding assembly 2 includes a support leg 21 arranged on one side of the gantry 11 and a bottle feeding conveyor belt mechanism 22 installed on the top of the support leg 21. The bottle feeding conveyor belt mechanism 22 can be a rubber conveyor belt mechanism. When the finished fire extinguisher is placed on the top of the bottle feeding conveyor belt mechanism 22, the bottle feeding conveyor belt mechanism 22 conveys the finished fire extinguisher, and then the conveyed finished fire extinguisher is adsorbed and grasped by the grasping mechanism 4 and placed in the packaging box.

[0043] In order to facilitate the grabbing of the grabbing mechanism 4, the finished fire extinguisher is in a standing state during the transportation process. Therefore, in order 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 limited and guided by the two guide plates 23 during the transportation process.

[0044] After the finished fire extinguisher is placed inside the packaging box, the staff puts the accessories (spray hose) into the packaging box and then adjusts the position of the accessories. The packaging box loaded with the finished fire extinguisher and accessories is then sent to the sealing station via the conveyor belt mechanism 153 for sealing.

[0045] In the second embodiment, the existing method has significant disadvantages due to the need for manual placement of accessories: on the one hand, manual operation is inefficient, which restricts the efficiency of the overall packing process; on the other hand, manual operation is prone to errors, resulting in omission or misplacement of accessories. During packing, accessories often fold, overlap and squeeze each other. If they are directly packaged, it will affect the sealing operation of the box lid. Therefore, the staff still needs to make repeated adjustments, which brings inconvenience to the subsequent links.

[0046] See Figure 1 、 Figures 8-10 To this end, a delivery pipe assembly 3 is provided on the side of the conveying assembly 1 away from the bottle delivery assembly 2. The delivery pipe assembly 3 can automatically deliver the accessories and grab the accessories to the location of the packaging box. The specific structure of the delivery pipe assembly 3 is as follows: See Figure 1 、 Figures 8-10 The pipe feeding assembly 3 includes a support frame 31 arranged on one side of the gantry 11 and a pipe feeding conveyor belt mechanism 32 installed on the top of the support frame 31. A plurality of pipe feeding clamps 33 are installed on the conveyor belt surface of the pipe feeding conveyor belt mechanism 32. A flipping mechanism 34 is installed on the side of the support frame 31 close to the auxiliary conveying mechanism 14. A group of pipe feeding clamps 33 is used to clamp a spray hose, and multiple groups of pipe feeding clamps 33 are arranged at equal distances and are driven to move synchronously by the pipe feeding conveyor belt mechanism 32. When one group of pipe feeding clamps 33 moves to the adaptation position of the flipping mechanism 34, the flipping mechanism 34 flips over to clamp the spray hose on this group of pipe feeding clamps 33, and then flips it again to the position of the packaging box to feed the spray hose, thereby facilitating the packing operation of the spray hose accessories.

[0047] See Figure 8 and Figure 9 The specific structure of the flip mechanism 34 is as follows: The flip mechanism 34 includes two fixed plates 341 installed on the side of the support frame 31 close to the auxiliary conveying mechanism 14 and a rotating rod 343 rotatably connected between the two fixed plates 341, a servo motor 342 is installed 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, the outer wall of the rotating rod 343 is connected to a U-shaped plate 344, the servo motor 342 is used to drive the rotating rod 343 to rotate, thereby driving the U-shaped plate 344 to swing, the top of the U-shaped plate 344 is slidably connected to two bearing plates 345, and the ends of the two bearing plates 345 away from the U-shaped plate 344 are equipped with electric clamps 34 6. During the swinging process, the U-shaped plate 344 drives the two supporting plates 345 to swing, thereby driving the electric clamp 346 to move. The electric clamp 346 is used to clamp the spray hose. Two sliding grooves 347 are symmetrically opened on the U-shaped plate 344. The inside of the two sliding grooves 347 are slidably connected with sliders 348. The two sliders 348 are arranged corresponding to the two supporting plates 345, and the sliders 348 are connected to the corresponding supporting plates 345. Two adjusting cylinders 349 are installed on the top of the U-shaped plate 344. The two adjusting cylinders 349 are arranged corresponding to the two supporting plates 345, and the piston rods of the adjusting cylinders 349 are connected to the corresponding supporting plates 345.

[0048] When the spray hose is transported by the turning mechanism 34, the U-shaped plate 344 and the carrying plate 345 are first controlled to swing, thereby adjusting the position of the electric clamp 346, and the electric clamp 346 moves to the position of one group of pipe feeding clamps 33. Then, the cylinder 349 is adjusted to push the carrying plate 345 to move, and the carrying plate 345 drives the electric clamp 346 to approach the direction of the pipe feeding clamp 33, and the electric clamp 346 is sleeved on the outside of the spray hose. Then the electric clamp 346 clamps the spray hose, and the pipe feeding clamp 33 releases the spray hose. The U-shaped plate 344 is turned over again, and the electric clamp 346 takes the spray hose out of the pipe feeding clamp 33 and moves it to the position of the packaging box, and by adjusting the cylinder 349 to extend again, the carrying plate 345 drives the electric clamp 346 and the spray hose to move further toward the packaging box. After the electric clamp 346 cancels the clamping, the spray hose can be loaded into the packaging box, thereby achieving the purpose of automatic packing of the spray hose.

[0049] In the third embodiment, when the existing finished fire extinguishers are placed inside the box, in order to ensure that the nozzle parts of the two fire extinguishers do not interfere with each other after the fire extinguishers are placed, the nozzles of the fire extinguishers are staggered. However, when placed in this way, the nozzles are easily offset, and the spray hose is generally placed between the two fire extinguishers. In addition, the length of the accessories may exceed the inner diameter of the box. If the nozzle is offset, it will interfere with the placement of the spray hose, and the spray hose will pop out of the packaging box at the same time, affecting the subsequent sealing operation.

[0050] See Figure 1 、 Figure 3 and Figure 4 To this end, a placement component 5 is installed on the internal top wall of the gantry 11, and a bracket component 6 is provided at the bottom of the placement component 5. Both the placement component 5 and the bracket component 6 are located above the auxiliary conveying mechanism 14. The bracket component 6 is used to position the finished fire extinguisher, and the placement component 5 is used to drive the bracket component 6 to move, so as to facilitate the placement of the bracket component 6 into the packaging box. A second conveying mechanism 16 is provided on the side of the gantry 11 away from the first conveying mechanism 13. The second conveying mechanism 16 is used to convey the bracket component 6. When the packaging box and the bracket component 6 are conveyed, the second conveying mechanism 16 is first used to move the bracket component 6 to the auxiliary conveying mechanism 14, and then the auxiliary conveying mechanism 14 and the transition conveying mechanism 17 cooperate to move the bracket component 6 to the bottom of the placement component 5. Then the bracket component 6 is lifted by the placement component 5. At this time, the bracket component 6 can carry out the loading operation of the finished fire extinguisher and accessories. At the same time, the first conveying mechanism 13 transports the packaging box and moves the packaging box to the transition conveying mechanism 17 for parking. At the same time, the packaging box is below the bracket component 6, which facilitates the placement and packing of the bracket component 6.

[0051] See Figure 1 、 Figure 3-Figure 5 , the specific structure of placement component 5 is as follows: The placement component 5 includes an electric linear module 503 installed on the internal top wall of the gantry 11. The driving direction of the electric linear module 503 is the same as the conveying direction of the conveyor belt mechanism 153. The bottom of the electric linear module 503 is slidably connected to the scissor rod mechanism 51. The bottom of the scissor rod mechanism 51 is installed with a connecting plate 53. The electric linear module 503 can be a stepper motor linear guide screw slide module, which is not specifically limited here. The scissor rod mechanism 51 is driven to slide by the electric linear module 503. The scissor rod mechanism 51 is used to drive the connecting plate 53 to move in the height direction. A rotating cylinder 52 is installed on the top of the connecting plate 53. The output end of the rotating cylinder 52 passes through the connecting plate 53 and is connected to the 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 rotating cylinder 52 is used to drive the rotating plate 54, the connecting plate 56 and the connecting rod 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. The two output ends of the forward and reverse motor 57 are connected to a screw rod 59. The thread directions of the two screw rods 59 are opposite, and the outer walls of the two screw rods 59 are threadedly connected to a connecting block 58. The bottom of the two connecting blocks 58 are connected to a movable frame 501, which is slidably connected to the top of the connecting plate 56. The bottom of each movable frame 501 extends downward and is connected to an insert plate 502. The forward and reverse motor 57 is used to drive the screw rod 59 to rotate forward or reverse. The two connecting blocks 58 move back and forth according to the rotation direction of the screw rod 59. The two connecting blocks 58 respectively drive the corresponding movable frame 501 and the insert plate 502 to move. When the two movable frames 501 approach each other, the insert plate 502 can be connected to the bracket assembly 6. When the two movable frames 501 move away from each other, the bracket assembly 6 can be released.

[0052] Specifically, a long hole groove is provided on the top of the mobile frame 501, and one side of the long hole groove is open. When the two mobile frames 501 move and separate, the connecting rod 55 can slide into the inside of the long hole groove, thereby preventing the connecting rod 55 from obstructing the movement of the mobile frame 501; the mobile frame 501 is U-shaped when viewed from the side, and the connecting plate 56 is inside the mobile frame 501, and will not cause any obstruction in the initial state. When the mobile frame 501 moves, the connecting plate 56 always moves inside the mobile frame 501. Therefore, the mobile frame 501 will not interfere with the connecting plate 56 when it is moving.

[0053] Specifically, when the bracket assembly 6 moves to the bottom of the placement assembly 5, the connecting plate 53 is first driven downward by the scissor rod mechanism 51, causing the components below the connecting plate 53 to move downward as a whole, and the two mobile frames 501 move to the two sides of the bracket assembly 6. Then, by driving the two mobile frames 501 close to each other, the plug plate 502 is inserted into the interior of the bracket assembly 6. At this time, the bracket assembly 6 is grasped, and then the scissor rod mechanism 51 contracts, and the mobile frame 501 and the plug plate 502 cooperate to lift the bracket assembly 6 to a certain height. At this time, the packaging box can be transported.

[0054] At this time, the grabbing mechanism 4 grabs the finished fire extinguisher from the pipe conveyor belt mechanism 32 and adjusts the placement angle, and places the finished fire extinguisher into the placement position inside the bracket assembly 6, and then drives the rotating plate 54 and the various components under the rotating plate 54 to rotate synchronously through the rotating cylinder 52, and then adjusts 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 loaded, the electric linear module 503 can drive the scissor rod mechanism 51 and the various components under the scissor rod mechanism 51 horizontally toward the direction of the pipe conveyor assembly 3, and the bracket assembly 6 moves to the position of the flipping mechanism 34. The flipping mechanism 34 places the spray hose into the inside of the bracket assembly 6. After the spray hose is placed, the bracket assembly 6 is reset and driven downward by the scissor rod mechanism 51 to sink into the packaging box. After that, the fully loaded packaging box can be moved out through the conveyor belt mechanism 153.

[0055] See Figure 5 and Figure 6 The specific structure of the bracket assembly 6 is as follows: The bracket assembly 6 includes a top plate 61. The top plate 61 is hollow and has an opening on the side of the top plate 61 facing the insert plate 502. The insert plate 502 is inserted into the interior of the top plate 61 through the opening. The top plate 61 is used to connect with the insert plate 502 to facilitate the entire grasping and transfer of the bracket assembly 6. The bottom of the top plate 61 is provided with two stacked placement racks 62. The placement racks 62 are used to place and support the finished fire extinguisher and the spray hose.

[0056] See Figure 5 and Figure 6, the two placement rack mechanisms 62 each include an I-shaped frame 621, a vertical plate 622 is connected to the middle of the opposite side of the two I-shaped frames 621, and a pipe clamp 623 for clamping the fire extinguisher is symmetrically installed on both sides of the vertical plate 622. The pipe clamp 623 is used to carry and place the finished fire extinguisher. The finished fire extinguishers on the same side of the two placement rack mechanisms 62 are placed in the same direction. When the finished fire extinguisher is placed, one side of the pipe clamp 623 on the bracket assembly 6 is set towards the bottle feeding assembly 2, and the grabbing mechanism 4 first puts the finished fire extinguisher Grab it and place it horizontally inside the pipe clamp 623. The nozzle part of the finished fire extinguisher fits to one side of the vertical plate 622. After the pipe clamp 623 on one side of the bracket assembly 6 is loaded, the bracket assembly 6 rotates 180 degrees as a whole. The grabbing mechanism 4 grabs the finished fire extinguisher again for placement. The angles at which the grabbing mechanism 4 grabs the four finished fire extinguishers and the adjusted placement angles are the same, and the adaptability is strong. There is no need to set up two conveying lines for conveying finished fire extinguishers in different directions or to set up a separate mechanism for adjusting the angle of the finished fire extinguisher.

[0057] See Figure 5 and Figure 6 A plug rod 63 and a plug tube 64 are provided between the two I-shaped frames 621. The plug rod 63 is connected to one of the I-shaped frames 621, and the plug tube 64 is connected to the other I-shaped frame 621. The plug rod 63 and the plug tube 64 are mutually limited and plugged. The two placement rack mechanisms 62 are connected through the plug rod 63 and the plug tube 64. The plug rod 63 can slide inside the plug tube 64, and a protrusion is provided on the outer wall of the plug rod 63, and a through groove is provided on the outer wall of the plug tube 64. The protrusion can slide inside the through groove, that is, it is ensured that when the plug rod 63 slides inside the plug tube 64, the two will not rotate relative to each other.

[0058] When the bracket assembly 6 is lifted by the placement assembly 5, the placement rack mechanism 62 below moves downward under the influence of gravity, causing the insertion rod 63 to slide inside the insertion tube 64, and a placement gap is pulled out between the two placement rack mechanisms 62. After the finished fire extinguishers are loaded on the two placement rack mechanisms 62, the bracket assembly 6 approaches the direction of the delivery pipe assembly 3, and the flipping mechanism 34 grabs the spray hose and inserts the spray hose into this placement gap, thereby realizing the filling of the spray hose. The top surface of the top plate 61 on the top of the bracket assembly 6 is flat, and when the packaging box is sealed, the spray hose will not pop out and affect the sealing.

[0059] Since the length of the spray hose exceeds the length of the finished bottle of the fire extinguisher, in order to reduce the bending amount of the spray hose during loading, when loading the spray hose, the spray hose is first removed from the pipe delivery clamp 33 using the flipping mechanism 34, and then flipped to the placement gap position between the two placement rack mechanisms 62. Subsequently, the two adjusting cylinders 349 are driven to start, and the two adjusting cylinders 349 are extended at the same time, causing the electric clamp 346 to place the spray hose into the placement gap. At this time, one of the adjusting cylinders 349 stops extending, and the other adjusting cylinder 349 continues to extend, causing the spray hose to be placed in the placement gap, and the spray hose is placed diagonally in the placement gap, reducing the bending amount of the spray hose.

[0060] After the load is complete, the bottom of the bracket assembly 6 sinks into the packaging box first, and the inserting plate 502 is pulled out from the top plate 61, and the bracket assembly 6 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 insertion rod 63 slides into the inside of the insertion tube 64. The placement gap between each placement rack mechanism 62 is reduced. In order to ensure that the spray hose is not crushed, the length of the insertion rod 63 is used for auxiliary support. At the same time, the interior of the I-shaped frame 621 is connected with a reinforcing rib 624, and the reinforcing rib 624 is used to assist in supporting the spray hose to prevent the spray hose from sagging. In addition, a pressure block 625 is connected to the four corners of each I-shaped frame 621, and the pressure block 625 extends between the two I-shaped frames 621. The pressure blocks 625 at the corresponding positions on the two I-shaped frames 621 fit together, thereby assisting the support of the four corners of the two I-shaped frames 621, and the supporting effect is the same as the auxiliary support effect of the insertion rod 63 using its own length, thereby avoiding the spray hose from being crushed.

[0061] After the bracket assembly 6 is completely installed in 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 step of the packaging box sealing operation.

[0062] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
