[0014] The beneficial effects are as follows:

[0015] 1. The device relies on a core drive structure consisting of a servo motor and a three-blade switcher, integrating five major processes: packaging bag conveying and cutting, bag opening, fertilizer quantitative dispensing, bag heat sealing, and finished product unloading. Through a 120-degree staggered surround layout, the control rack station can automatically switch, eliminating the need for manual intervention in the connection between processes. Compared with the traditional manual transfer and separate equipment operation mode, it avoids the waiting time between processes, and the actions of each station are precisely coordinated through mechanical linkage, which can achieve continuous batch packaging, effectively increasing the packaging output per unit time, and is suitable for large-scale fertilizer production scenarios.

[0016] 2. The device uses a motor inside the speed-limited conveying chamber to drive the impeller, precisely controlling the amount of fertilizer falling based on the impeller speed, thus avoiding deviations caused by manual feeding. It adopts a double sealing structure with initial sealing by heat-sealing strips and secondary sealing by heat-sealing blocks, combined with the synchronous action of the cutter and sealing, which not only ensures a smooth cut on the packaging bag but also prevents fertilizer from getting damp and leaking due to poor sealing. In addition, the suction cup uses negative pressure to fix the bag opening, which, compared to manual opening, ensures a consistent opening width and avoids fertilizer spillage caused by bag opening deviation, further reducing material loss and packaging defect rate.

[0017] 3. The device has high adaptability in design. Firstly, it is compatible with unsealed cylindrical packaging bags, eliminating the need for pre-treatment of the packaging bags and reducing preliminary preparation steps. Secondly, by adjusting parameters such as impeller motor speed and heat sealing temperature, it can be adapted to fertilizers of different granule specifications and packaging bags of different sizes, without the need for frequent replacement of equipment parts. At the same time, the core drive components of the device are all standardized components with a clear structural layout, reducing the difficulty of troubleshooting. Attached Figure Description

[0031] Example 1: Please refer to the accompanying drawings in the instruction manual. Figures 1 to 10 As shown:

[0032] This invention proposes a fertilizer baling device with automatic switching function, comprising: a gearbox 1, a control shaft 101 rotatably mounted on the top of the gearbox 1, a servo motor 102 externally mounted on the gearbox 1 and connected to the control shaft 101; a three-lobe switcher 103 fixedly mounted externally on the control shaft 101; three sets of control frames 2 equidistantly fixedly mounted externally on the three-lobe switcher 103; the upper part of the control frame 2 is a frame structure, and guide tubes 201 are slidably mounted on the inner walls of both sides of the upper part of the control frame 2, and mounting plates 204 are fixedly mounted on the outer sides of adjacent ends of the guide tubes 201, with suction cups 205 fixedly mounted through the mounting plates 204 at the ends of the guide tubes 201; and springs are fitted and fixedly mounted on the other ends of the guide tubes 201. A trigger seat 202 is provided; a stand 6, with a connecting frame 601 fixedly installed on the top of one end of the stand 6, and a sealing and trimming device 7 fixedly installed at the bottom of the connecting frame 601; cylinders 701 are fixedly installed on the middle of both sides of the sealing and trimming device 7, and vertical plates 702 are fixedly installed on the telescopic ends of the cylinders 701; a hopper 10, with a speed-limiting conveyor 11 connected to the bottom of the hopper 10, an impeller motor 12 fixedly installed outside the speed-limiting conveyor 11, and a flat bucket 13 connected to the bottom of the speed-limiting conveyor 11 by an inclined pipe; a control frame 14, with an electric cylinder C15 fixedly installed on the top outer side of the control frame 14; the stand 6, the hopper 10 and the control frame 14 are arranged in a staggered 120-degree arrangement around the control shaft 101.

[0033] The trigger seat 202 has trapezoidal blocks 203 integrally installed on both the upper and lower sides; the control frame 2 has guide seats 206 fixedly installed on both sides, and trigger slide frames 3 are slidably installed outside the guide seats 206. The corner of the trigger slide frame 3 near the trapezoidal block 203 is beveled; the inside of the trigger slide frame 3 is fixedly installed at the end away from the trapezoidal block 203, and a spring rod A301 is installed on the spring rod A301. A spring is sleeved on the spring rod A301 and a baffle is fixedly installed through the guide seat 206.

[0034] Among them, the bottom of the control frame 2 is integrally provided with a bottom drag bar 207; a through bar groove 208 is opened in the upper middle part of the control frame 2; a connector 4 is fixedly installed on the outside of the control frame 2, and two sets of one-way valves 401 are connected to both ends of the connector 4; a docking hole is opened in the middle of the side of the connector 4 away from the control frame 2.

[0035] Among them, a press air valve 5 is fixedly installed below the position of the control frame 2 near the three-leaf switcher 103. The trigger end of the press air valve 5 has a long strip-shaped structure on the outside. Both the press air valve 5 and the one-way valve 401 are provided with air pipes connected to the trigger seat 202, which pass through the guide tube 201 and communicate with the suction cup 205.

[0036] The top of the connecting frame 601 is fixedly equipped with a conveyor 602, and four sets of rotating rollers 603 are rotatably arranged in the conveyor 602. The shaft ends of the two sets of rotating rollers 603 below are equipped with gear meshing. The top of the upright frame 6 is fixedly equipped with a conveyor motor 604, and the shaft end of the conveyor motor 604 is connected to the shaft end of the set of rotating rollers 603 below by gear transmission. The rotating rollers 603 are provided with spiral grooves.

[0037] Among them, the sealing and trimming device 7 is frame-shaped, and the vertical plate 702 is located inside the sealing and trimming device 7. A heat sealing strip 703 and a cutter 704 are fixedly installed on the outside of one set of vertical plates 702. The heat sealing strip 703 and the cutter 704 can fit into another set of vertical plates 702; the cutter 704 is located below the heat sealing strip 703.

[0038] An electric cylinder B8 is fixedly installed in the upright frame 6. A trigger plate 801 is fixedly installed at the telescopic end of the electric cylinder B8. Two sets of trigger rods 802 are fixedly installed on the upper part of the trigger plate 801. The trigger rods 802 can contact the trigger slide frame 3. The trigger plate 801 has a docking hole on its outside. The docking device 4 can dock with the docking hole of the trigger plate 801. Rubber rings are fixedly installed on the outside of the docking hole. An air pump 9 is fixedly installed on the outside of the upright frame 6. Pipes are respectively installed at both ends of the air pump 9 to connect to the docking hole of the cylinder 701 and the trigger plate 801. A steel wire hose is used as the air pipe to ensure that the air pipe will not be sucked flat when pumping air.

[0039] The speed-limiting conveying bin 11 has an internal rotating impeller, which is driven by an impeller motor 12; the bottom of the flat bucket 13 is higher than the mounting plate 204.

[0040] Among them, a slider 16 is slidably arranged above the control frame 14, and the telescopic end of the electric cylinder C15 is fixedly connected to the slider 16; two sets of through-sealing rods 17 are fixedly arranged outside the slider 16, and heat sealing blocks 18 are fixedly arranged on the adjacent surfaces of the two sets of through-sealing rods 17 away from the slider 16; the two sets of through-sealing rods 17 can pass through the through-rod slot 208.

[0041] The electric cylinder B8 is the core driving component. It moves the trigger plate 801 by pushing out, providing initial power for the subsequent sealing and opening of the bag opening.

[0042] The trigger plate 801, trigger rod 802, trigger slide frame 3, trapezoidal block 203, and trigger seat 202 are linkage components. After the trigger plate 801 is attached to the docking hole of the docking device 4, the trigger rod 802 pushes the trigger slide frame 3, and then presses the trapezoidal block 203 to make the trigger seat 202 close to the control frame 2, and finally achieves the attachment of the suction cups 205 on both sides to the packaging bag.

[0043] The suction cup 205 and the air pump 9 are key components for fixing and opening the bag opening. The air pump 9 draws out the air from the suction cup 205 and the pipe, generating negative pressure suction to fix the side of the bag opening. When the air pump 9 is driven in reverse, the cylinder 701 contracts and, in conjunction with the spring, returns to its original position to open the bag opening.

[0044] Spring rod A301 and guide tube 201 are reset components. During the reverse drive phase of air pump 9, the spring force drives spring rod A301 and guide tube 201 to reset, assisting in the smooth opening of the bag.

[0045] The bottom support bar 207 is a positioning component that ensures precise contact between the edge of the packaged bag roll during each feeding process, guaranteeing a stable bag opening position and facilitating subsequent adhesion by the suction cup 205.

[0046] The conveyor motor 604 and the rotating roller 603 are the power components for conveying the packaging bags. The conveyor motor 604 drives the rotating roller 603 to rotate, and the two sets of rotating rollers 603 below rotate synchronously to realize the stable downward conveying of the packaging bag roll and control the feeding rhythm.

[0047] The cylinder 701, vertical plate 702, heat sealing strip 703, and cutter 704 are integrated sealing and cutting components. The air pump 9 supplies air to the cylinder 701 to open it, which drives the two sets of vertical plates 702 to move closer together. The heat sealing strip 703 completes the sealing of the packaging bag, and at the same time, the cutter 704 cuts off the lower part of the seal, realizing the "sealing-cutting" synchronous operation. When the air pump 9 drives in the reverse direction, the cylinder 701 retracts and resets, preparing for the next round of operation.

[0048] Servo motor 102, three-lobe switcher 103, and control frame 2 are position switching and driving components. Servo motor 102 drives three-lobe switcher 103 and control frame 2 to rotate. Each rotation is one-third of a turn, which precisely switches the position of control frame 2 (from the bag opening position to the fertilizer dispensing position, and then to the final bag sealing position), ensuring smooth connection between each process.

[0049] Example 2:

[0050] In the quantitative fertilizer dispensing process, the impeller motor 12, the speed-limiting conveying chamber 11, the impeller, and the flat hopper 13 are the quantitative dispensing components. The impeller motor 12 drives the impeller in the speed-limiting conveying chamber 11 to rotate, and the speed and amount of fertilizer falling are controlled by the speed of the impeller to achieve quantitative dispensing. The flat hopper 13 serves as a guiding component to accurately guide the fertilizer into the opened packaging bag.

[0051] Example 3: Final sealing and unloading related components

[0052] The electric cylinder C15, slider 16, sealing rod 17, and heat sealing block 18 are secondary sealing components. The electric cylinder C15 pushes out the slider 16, which drives the sealing rod 17 to pass through the rod slot 208. The heat sealing block 18 performs secondary heat sealing on the packaging bag opening to ensure a tight seal.

[0053] The press valve 5 is a material unloading control component. When the sealing rod 17 continues to move, it contacts the trigger position of the press valve 5, causing it to open. Outside air is then supplied to the suction cup 205 pipe, eliminating the negative pressure suction and allowing the packaging bag to fall off naturally.

[0054] The conveyor belt is used for unloading and transfer. The finished packaging bags that fall off land on the top of the conveyor belt and are then transferred to the subsequent processing steps, completing the final transfer of the entire packaging process.

[0055] Air pump 9 is the global pneumatic power source, which not only provides power for the opening and closing of cylinder 701, but also controls the generation and disappearance of suction force of suction cup 205. It is the key power support for bag opening fixing, sealing and cutting, unloading and other processes.

[0056] The specific usage and function of this embodiment are as follows: In this invention, the packaging bag roll is wound in a cylindrical manner and does not need to be pre-heat-sealed. It is simply passed through the rotating roller 603 and arranged downwards. The packaging bag roll is arranged parallel to one side of the sealing and trimming device 7.

[0057] like Figure 1 A conveyor belt is arranged between the control box 14 and the gearbox 1;

[0058] Pour fertilizer into hopper 10.

[0059] The work steps are as follows:

[0060] The electric cylinder B8 is activated to push out the trigger plate 801, which fits the trigger plate 801 and the docking hole of the docking device 4. At the same time, the trigger rod 802 pushes the trigger slide frame 3 to move, and the trigger slide frame 3 presses the trapezoidal block 203 to move the trigger seat 202 closer to the control frame 2, thereby making the suction cups 205 on both sides fit onto the packaging bag.

[0061] Start the conveyor motor 604 to drive the rotating roller 603 to rotate. The two sets of rotating rollers 603 below rotate simultaneously to convey the packaging bag roll downwards. Each feed will bring the edge of the packaging bag roll to contact the bottom support bar 207.

[0062] Start the air pump 9 to input air into the cylinder 701, which opens the cylinder 701 and pushes the two sets of vertical plates 702 together. The heat sealing strip 703 is used to seal the packaging bag, and the cutter 704 is used to cut off the lower part of the seal. At the same time, the air in the suction cup 205 and its pipe is extracted, generating suction to fix the side of the cut packaging bag opening. The one-way valve 401 keeps the suction cup 205 under negative pressure.

[0063] Then, the reverse drive air pump 9 retracts and resets the cylinder 701, triggering the slide frame 3 to reset via the spring outside the spring rod A301. The spring rod A301 automatically resets via the spring outside the guide tube 201, causing the bag opening of the packaging bag to open.

[0064] The servo motor 102 is started to drive the three-blade switcher 103 and the control frame 2 to rotate. After rotating one-third of a turn, the position is switched. The impeller motor 12 is started to drive the impeller in the speed-limiting conveying chamber 11 to rotate, and the fertilizer is quantitatively fed downwards. The fertilizer is put into the packaging bag through the flat hopper 13.

[0065] Then rotate the control frame 2 one-third of a turn to align the control frame 2 with the control frame 14. Then start the electric cylinder C15 to push out the slider 16. The sealing rod 17 passes through the rod slot 208 and continues to move. The heat sealing block 18 is used to heat seal the bag opening.

[0066] After heat sealing, the sealing rod 17 continues to move and contacts the trigger position of the pressing air valve 5, opening the pressing air valve 5. Outside air is supplied into the pipe of the suction cup 205, which releases the negative pressure in the suction cup 205 and the suction disappears. At this time, the packaging bag falls and lands on the top of the conveyor belt, and is transferred to the subsequent processing process by the conveyor belt.

[0067] By repeating the above steps, automatic packaging can be continuously performed.
