Description

Technical Field

[0001] The present invention relates to the technical field of packaging machines, and specifically to an agricultural powder fertilizer production packaging machine. Background Art

[0002] Traditional agricultural powder fertilizer packaging machines mostly adopt the "filling - conveying - sealing" production line mode. Its core process is as follows: First, the powder fertilizer is accurately filled into the packaging bag through a screw feeder or a gravity metering device, and then the bag filled with fertilizer is smoothly transferred to the heat - sealing or sewing - sealing station by a horizontal conveyor belt. However, this traditional design has significant defects in practical applications. Especially in the conveying link, the stability problem of the packaging bag caused by inertia has been a concern and urgently needs to be effectively solved.

[0003] An existing packaging machine, such as a powder screw packaging machine proposed in the patent application number "CN221699078U", includes a frame plate. The upper surface of the frame plate is fixedly connected with a material - conveying cylinder. The outer wall of the material - conveying cylinder is fixedly connected with a fixed block. A connecting column is rotatably connected inside the fixed block. One end of the connecting column is fixedly connected with a rotating handle. The other end of the connecting column is fixedly connected with a moving plate. A pulling plate is rotatably connected to the outer wall of the moving plate. A combined position plate is rotatably connected to the outer wall of the pulling plate. The outer wall of the frame plate is fixedly connected with a support plate. A limiting block is fixedly connected to the inner wall of the support plate.

[0004] However, in practical applications, the above - mentioned patented technology exposes some obvious defects. When the powder is put into the packaging bag through the material - conveying cylinder and then the second motor is started to drive the conveyor belt to convey the powder to the next process in cooperation with the connecting shaft, since the direction of the inertial force received by the packaging bag is the same as the length direction of the conveyor belt, and the direction of the gravity received by the packaging bag is perpendicular to the direction of the inertial force, this causes the packaging bag to be prone to tilt or fall under the action of inertia, affecting the packaging stability of the device.

Detailed Embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0035] An agricultural powder fertilizer production and packaging machine drives a fertilizer bag to be transferred up and down and transferred into the heat sealing mechanism for sealing, asFigure 3 and Figure 4 As shown, a loading and unloading mechanism is used to position and guide the fertilizer bag, so that when the packaging machine drives the fertilizer bag to move, the gravity direction of the fertilizer bag is parallel to the inertia force direction, thereby improving the stability of the packaging process. It belongs to a kind of intelligent packaging device.

[0036] As Figures 1-8 shown, it includes a base 1. A storage hopper 2 is fixedly connected to the top of the base 1. The output end of the storage hopper 2 is fixedly connected to a loading cylinder 3. One end of the loading cylinder 3 is fixedly connected to a loading head 4. A storage bin 5 is opened at one end inside the base 1, and a transfer bin 6 communicating with the storage bin 5 is opened at the other end inside the base 1. A conveyor belt 7 is arranged inside the transfer bin 6. An electric push rod 1 is fixedly connected to the bottom of the base 1. The output end of the electric push rod 1 is fixedly connected to a bearing platform 9. The bearing platform 9 is installed inside the storage bin 5, and support sliding rods 10 slidably passing through the base 1 are fixedly connected to the four corners of the bottom of the bearing platform 9. A blanking rod 11 is hinged to the middle section of the top of the bearing platform 9;

[0037] A loading and unloading mechanism for guiding the stable loading and unloading of the fertilizer bag is installed at one end of the base 1, and a heat sealing mechanism for sealing the fertilizer bag is installed at one end of the base 1. A feeding mechanism for quantitatively feeding the fertilizer into the fertilizer bag is installed at one end of the loading cylinder 3.

[0038] During use, first, place the fertilizer bag on the top of the bearing platform 9, and start the feeding mechanism to cooperate with the loading head 4 to introduce the fertilizer powder into the fertilizer bag. At the same time, set two support sliding rods 10 to resist and limit the periphery of the fertilizer bag filled with fertilizer powder to ensure the stable placement of the fertilizer bag. Then, start the electric push rod 1 to drive the bearing platform 9 to move downward along the length direction of the support sliding rods 10, so that the bearing platform 9 drives the fertilizer bag to move to one side of the conveyor belt 7. At this time, the bottom of the fertilizer bag is parallel to the top of the conveyor belt 7;

[0039] During the process of the bearing platform 9 driving the fertilizer bag to move downward along the length direction of the support sliding rods 10, ensure that the weight direction of the fertilizer is consistent with the inertia force direction generated by the movement to reduce the situation of the fertilizer pouring around. When the sealing end of the fertilizer bag moves to the specified position, use the heat sealing mechanism to complete the sealing of the fertilizer bag mouth. Subsequently, when the bearing platform 9 drives the fertilizer bag to move downward along the length direction of the support sliding rods 10 to be parallel to the top of the conveyor belt 7, cooperate with the loading and unloading mechanism to push the fertilizer bag to pour to one side of the conveyor belt 7. At this time, use the self-weight of the fertilizer to push the fertilizer bag to fall onto the top of the conveyor belt 7. Finally, start the conveyor belt 7 to transfer the packaged fertilizer to the next process. In this way, during the process of transferring the fertilizer bag to the sealing process, keep the weight direction of the fertilizer bag consistent with the inertia force direction, thereby improving the stability of the fertilizer bag during transfer.

[0040] As Figures 2-7As shown in the figure, the loading and unloading mechanism includes follower slide rails 12 symmetrically opened at the top of the bearing platform 9. A V-shaped clamping plate 13 is slidably connected inside the follower slide rails 12. One end of the V-shaped clamping plate 13 is rotatably sleeved with a limiting sleeve roller 14. Limiting chute grooves 15 are symmetrically opened on the inner side of the storage bin 5. An outward expansion chute groove 16 is opened at the bottom of the limiting chute groove 15. One end of the limiting sleeve roller 14 is inserted into the limiting chute groove 15. One end of the bearing platform 9 is equipped with a blanking mechanism for pushing the fertilizer bag to fall onto the top of the conveyor belt 7;

[0041] Among them, the blanking mechanism includes a storage groove 17 opened in the middle section of the top of the bearing platform 9. The blanking rod 11 is installed inside the storage groove 17. Z-shaped lifting rods 18 are symmetrically and rotatably connected inside the storage groove 17. A synchronous gear 19 is fixedly connected between the two Z-shaped lifting rods 18. One end of the Z-shaped lifting rod 18 is rotatably sleeved with a lifting sleeve roller 20. Lifting chute grooves 21 are symmetrically opened at one end of the blanking rod 11. One end of the Z-shaped lifting rod 18 is inserted into the lifting chute groove 21. A top-out chute groove 22 is opened at the bottom of the storage groove 17. A top-out rack 23 is slidably connected inside the top-out chute groove 22. One end of the base 1 is equipped with a top-out assembly for driving the top-out rack 23 to move along the length direction of the top-out chute groove 22;

[0042] Moreover, the top-out assembly includes a first reset spring 24 symmetrically and fixedly connected to one end of the top-out rack 23. The first reset spring 24 is installed inside the storage groove 17. One end of the top-out rack 23 is rotatably connected with a roller 25. A through groove 26 communicating with the inside of the storage bin 5 is opened at one end of the base 1. A top-out inclined block 27 adapted to the roller 25 is fixedly connected to the inner bottom of the through groove 26.

[0043] During use, first, start the first electric push rod 8 to move the bearing platform 9 upward along its length direction. This action drives the two limiting sleeve rollers 14 to slide along the guiding direction of the outward expansion chute groove 16 into the limiting chute groove 15, and prompts the two limiting sleeve rollers 14 to push the two supporting slide rods 10 to approach each other along the length direction of the follower slide rails 12. As the bearing platform 9 rises, the limiting sleeve rollers 14 slide inside the limiting chute groove 15, shortening the distance between the two supporting slide rods 10, which is convenient for guiding the supporting slide rods 10 to contact the periphery of the bag filled with fertilizer powder on the top of the bearing platform 9, thereby enhancing the placement stability of the fertilizer bag on the top of the bearing platform 9;

[0044] Subsequently, the electric push rod 8 is started again to move the support platform 9 downward along its length direction. At this time, the heat sealing mechanism is used to seal the fertilizer bag on the top of the support platform 9. When the support platform 9 drives the fertilizer bag to move to a position parallel to the top of the conveyor belt 7, the limiting roller 14 slides along the guiding direction of the limiting slide groove 15 to the inside of the outward extension slide groove 16, and along the guiding direction of the outward extension slide groove 16, pushes the two limiting rollers 14 away from each other along the length direction of the follower slide rail 12. At the same time, the two limiting rollers 14 push the two supporting slide bars 10 away from each other along the length direction of the follower slide rail 12, thereby releasing the clamping of the fertilizer bag on the top of the support platform 9. When the support platform 9 drives the fertilizer bag to move to a position parallel to the top of the conveyor belt 7, the ejection rack 23 moves downward along the length direction of the through slot 26, and drives the roller 25 to form rolling contact with the ejection ramp 27. At the same time, the roller 25 pushes the ejection rack 23 to squeeze the return spring 24 along the length direction of the ejection chute 22 to produce contraction deformation, and makes the ejection rack 23 mesh with the synchronous gear 19 along the length direction of the ejection chute 22. Then, the synchronous gear 19 drives the Z-shaped lifting rod 18 to deflect upward around the hinge axis, so that the Z-shaped lifting rod 18 drives the lifting sleeve roller 20 to form rolling contact with the inner wall of the lifting chute 21, and pushes the unloading rod 11 to eject and deflect upward around the hinge axis. In this way, the unloading rod 11 pushes the fertilizer bag placed on the top of the support platform 9 to tip to one side of the conveyor belt 7. Finally, the conveyor belt 7 is started to drive the fertilizer bag to leave the top of the support platform 9 and enter the next process.

[0045] When the electric push rod 18 is started to push the support platform 9 to move upward along the length direction of the support slide bar 10, the roller 25 can be driven to break away from the rolling conflict with the ejection inclined block 27 along the length direction of the through slot 26, and the ejection rack 23 can be pushed to reset along the length direction of the ejection chute 22 by using the rebound characteristics of the reset spring 124, and the ejection rack 23 is driven to mesh with the synchronous gear 19, and the synchronous gear 19 drives the Z-shaped lifting rod 18 to deflect downward around the hinge axis, and the Z-shaped lifting rod 18 drives the lifting sleeve roller 20 to form a rolling conflict with the inner wall of the lifting chute 21, and pulls the unloading rod 11 to deflect around the hinge axis to the inside of the storage slot 17. This series of actions realizes the limit and automatic unloading of the fertilizer bag, and further improves the stability of the fertilizer bag during the transfer process.

[0046] like Figure 1 , Figure 4 , Figure 7 , Figure 8As shown, the heat sealing mechanism includes a pair of folding rods 28 symmetrically hinged at one end of the base 1, a heat sealer 29 is hinged between the two folding rods 28 oppositely arranged across the base 1, a lifting chute 30 symmetrically opened at one end of the base 1 and connected to the inside of the storage bin 5, a T-shaped lifting slide bar 31 is slidably connected to the inside of the lifting chute 30, a transmission chute 32 is symmetrically opened at one end of the T-shaped lifting slide bar 31, a transmission chute 32 is symmetrically opened at the bottom of the folding rod 28, a transmission rod 33 adapted to the transmission chute 32 is rotatably connected to the bottom of the folding rod 28, and a transmission component for driving the T-shaped lifting slide bar 31 to move along the length direction of the lifting chute 30 is installed at one end of the support platform 9;

[0047] Among them, the transmission assembly includes a guide slide rod 34 fixedly connected to the inside of the lifting slide groove 30, one end of the guide slide rod 34 is sleeved with a return spring 2 35, and the return spring 2 35 is installed under the T-shaped lifting slide rod 31. One end of the support platform 9 is symmetrically fixedly connected with a follower pressure rod 36, and one end of the follower pressure rod 36 is slidably sleeved on the periphery of the guide slide rod 34.

[0048] When in use, when the electric push rod 1 8 is started to drive the support platform 9 to drive the fertilizer bag to move downward, and the sealing end of the fertilizer bag moves between the two heat sealers 29, the support platform 9 drives the follower pressure rod 36 to slide downward along the length direction of the guide slide rod 34, and forms a conflict with the T-shaped lifting slide rod 31, and at the same time pushes the T-shaped lifting slide rod 31 to squeeze the return spring 2 35 to produce a contraction deformation, and the T-shaped lifting slide rod 31 drives the transmission slide groove 32 to form a rolling conflict with the transmission rod 33, and at the same time pushes the transmission rod 33 to drive the folding rod 28 to deflect around the hinged end with the base 1, and the two folding rods 28 drive the two heat sealers 29 to move closer to each other, and at the same time the two heat sealers 29 form a clamping heat seal on the sealing end of the fertilizer bag;

[0049] When the feeding mechanism pushes the fertilizer bag to the top of the conveyor belt 7, the weight of the fertilizer is used to pull the sealed end of the fertilizer bag out of between the two heat sealers 29, and the sealing of the fertilizer bag is completed. When the electric push rod 18 is started to drive the support platform 9 to move upward along the length direction of the supporting slide bar 10, the follow-up pressure rod 36 is driven to release the resistance to the T-shaped lifting slide bar 31, so as to use the rebound characteristics of the reset spring 2 35 to push out the T-shaped lifting slide bar 31, and make the T-shaped lifting slide bar 31 drive the transmission slide groove 32 and the transmission rod 33 to form a rolling resistance, and push the two folding rods 28 to drive the heat sealer 29 to move away from each other around the hinge axis, so as to facilitate the timely sealing operation of the sealed end of the fertilizer bag after the loading is completed, and effectively reduce the overflow of fertilizer during the transfer process due to untimely sealing.

[0050] like Figures 1-4 , Figure 9 , Figure 10As shown in the figure, the feeding mechanism includes a feeding auger 37 rotatably connected inside the loading cylinder 3. One end of the feeding auger 37 passes through the loading cylinder 3 and is fixedly connected with a first bevel gear 38. One end of the loading cylinder 3 is fixedly connected with a loading motor 39. The output end of the loading motor 39 is fixedly connected with a second bevel gear 40 meshing with the first bevel gear 38. The output end of the first electric push rod 8 is internally provided with a gravity sensor. One end of the loading head 4 is provided with a closing component for preventing fertilizer from falling into the fertilizer bag.

[0051] Among them, the closing component includes a pair of long rods 41 symmetrically hinged outside the loading head 4. An arc-shaped material receiving hopper 42 is hinged between the two long rods 41 arranged oppositely across the loading head 4. One end of the top of the arc-shaped material receiving hopper 42 is hinged with a short rod 43. One end of the short rod 43 is hinged with the loading head 4. One end of the loading cylinder 3 is provided with an adjusting component for driving the long rod 41 to deflect around the hinge axis.

[0052] Moreover, the adjusting component includes adjusting chutes 44 symmetrically opened outside the loading head 4. An adjusting rack 45 is slidably connected inside the adjusting chutes 44. The hinged end of the long rod 41 and the loading head 4 is fixedly connected with an adjusting gear 46 meshing with the adjusting rack 45. One end of the loading cylinder 3 is symmetrically hinged with second electric push rods 47. The output ends of the second electric push rods 47 are hinged with the adjusting rack 45.

[0053] Moreover, one end of the loading head 4 is fixedly connected with a dust collection hood 49. One end of the base 1 is fixedly connected with a cyclone separator 50. The air inlet of the cyclone separator 50 is fixedly connected with a dust suction pipe 51. The air inlet of the dust suction pipe 51 extends into the dust collection hood 49. One end of the base 1 is fixedly connected with an air pump 52. The input end of the air pump 52 is fixedly connected with an exhaust pipe 53. The input end of the exhaust pipe 53 is communicated with the air outlet of the cyclone separator 50.

[0054] During use, first, set the gravity sensor to model HBM U9B, so that the fertilizer raw materials inside the storage hopper 2 fall into the loading cylinder 3 under the action of gravity. At this time, start the loading motor 39 to drive the second bevel gear 40 to mesh with the first bevel gear 38, and make the first bevel gear 38 drive the feeding auger 37 to rotate, and make the feeding auger 37 push the fertilizer raw materials along the length direction of the loading cylinder 3 towards the loading head 4 and pass through the loading head 4 and fall into the fertilizer bag placed on the top of the bearing platform 9. At this time, make the bearing platform 9 transfer the increased weight of the fertilizer raw materials inside the fertilizer bag to the gravity sensor internally provided at the output end of the first electric push rod 8.

[0055] During the process that the fertilizer raw materials pass through the loading head 4 and fall into the interior of the fertilizer bag, a dust collection hood 49 is arranged to cover the escaped dust. At the same time, the air pump 52 is started to suck the dust covered by the dust collection hood 49 through the dust suction pipe 51, so that the dust flows into the interior of the cyclone separator 50 through the dust suction pipe 51 for collection. By using the cyclone separation principle, the dust particles in the air fall to the inner bottom of the cyclone separator 50 for collection, while the air enters the interior of the air pump 52 through the exhaust pipe 53 and then is discharged from the interior of the cyclone separator 50 through the air pump 52;

[0056] Moreover, when the gravity sensor senses that the weight of the fertilizer raw materials in the fertilizer bag reaches the standard, the electric push rod two 47 is started to pull the adjusting rack 45 around the hinge shaft, and the adjusting rack 45 is moved upward along the length direction of the adjusting chute 44. At the same time, the adjusting rack 45 is driven to mesh with the adjusting gear 46, and the adjusting gear 46 drives the long rod 41 to deflect, so that the two long rods 41 deflect towards each other around the hinge shaft, and the bottoms of the two arc-shaped material receiving hoppers 42 are driven to deflect towards each other by the two long rods 41. At the same time, the two arc-shaped material receiving hoppers 42 form an interception and wrapping around the bottom of the loading head 4, so as to facilitate the rapid closing of the loading head 4, effectively reducing the amount of fertilizer falling into the interior of the fertilizer bag during the non-loading stage, thereby realizing accurate quantitative loading.

[0057] The working principle of a kind of agricultural powder fertilizer production and packaging machine provided by the present invention is as follows:

[0058] First of all, the fertilizer bag is placed on the top of the bearing platform 9, and the loading motor 39 is started to drive the bevel gear two 40 to mesh with the bevel gear one 38, and the bevel gear one 38 drives the loading auger 37 to rotate, and the loading auger 37 pushes the fertilizer raw materials along the length direction of the loading cylinder 3 towards the direction of the loading head 4 and passes through the loading head 4 and falls into the fertilizer bag placed on the top of the bearing platform 9. At the same time, two support sliding rods 10 are arranged to resist and limit the periphery of the fertilizer bag filled with fertilizer powder;

[0059] Then, in the process of starting the electric push rod 18 to drive the support platform 9 to drive the fertilizer bag to move downward along the length direction of the supporting slide bar 10, ensure that the weight direction of the fertilizer is consistent with the inertial force direction generated by the movement. At the same time, when the support platform 9 drives the fertilizer bag to move to a position parallel to the top of the conveyor belt 7, the sealing end of the fertilizer bag moves between the two heat sealers 29, and at the same time, the support platform 9 drives the follower pressure rod 36 to slide downward along the length direction of the guide slide bar 34 and form a conflict with the T-shaped lifting slide bar 31, and at the same time, the T-shaped lifting slide bar 31 is pushed to squeeze the return spring 2 35 to produce a contraction deformation, and the T-shaped lifting slide bar 31 drives the transmission slide groove 32 to form a rolling conflict with the transmission rod 33, and at the same time, the transmission rod 33 is pushed to drive the folding rod 28 to deflect around the hinged end with the base 1, and the two folding rods 28 drive the two heat sealers 29 to move closer to each other, and at the same time, the two heat sealers 29 form a clamping heat seal on the sealing end of the fertilizer bag;

[0060] When the support platform 9 drives the fertilizer bag to move to a position parallel to the top of the conveyor belt 7, the limiting roller 14 slides along the guiding direction of the limiting slide groove 15 to the inside of the outward extension slide groove 16, and along the guiding direction of the outward extension slide groove 16, the two limiting rollers 14 are pushed away from each other along the length direction of the follower slide rail 12. At the same time, the two limiting rollers 14 push the two supporting slide bars 10 away from each other along the length direction of the follower slide rail 12, thereby releasing the clamping of the fertilizer bag on the top of the support platform 9;

[0061] At the same time, when the support platform 9 drives the fertilizer bag to move to a position parallel to the top of the conveyor belt 7, the ejection rack 23 moves downward along the length direction of the through slot 26, and drives the roller 25 to form rolling contact with the ejection inclined block 27. At the same time, the roller 25 pushes the ejection rack 23 to squeeze the return spring 1 24 along the length direction of the ejection chute 22 to produce contraction deformation, and the ejection rack 23 is meshed with the synchronous gear 19 along the length direction of the ejection chute 22. Then, the synchronous gear 19 drives the Z-shaped lifting rod 18 to deflect upward around the hinge axis, so that the Z-shaped lifting rod 18 drives the lifting sleeve roller 20 to form rolling contact with the inner wall of the lifting chute 21, and pushes the unloading rod 11 to eject and deflect upward around the hinge axis. In this way, the unloading rod 11 pushes the fertilizer bag placed on the top of the support platform 9 to tilt to one side of the conveyor belt 7. Finally, the conveyor belt 7 is started to drive the fertilizer bag to leave the top of the support platform 9 and enter the next process.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
