Description

Technical Field

[0001] The invention belongs to the technical field related to packaging machines, and specifically discloses an automatic quantitative packaging machine for seaweed fertilizer production. Background Art

[0002] Seaweed fertilizer is a kind of fertilizer produced and processed from marine brown algae or mixed with a certain amount of nitrogen, phosphorus, potassium and trace elements. Currently, it is mainly powdered on the market.

[0003] After searching, the Chinese patent publication number CN204713504U discloses a fertilizer packaging machine, which includes a frame, a feeding barrel, an adjustment frame, a conveyor belt, and an electrical control box. The feeding barrel is connected to the top of the frame via the adjustment frame, the upper portion of the feeding barrel is connected to the suction motor, the lower portion of the feeding barrel is provided with a material bag support frame, the conveyor belt is provided at the lower portion of the material bag support frame, and the conveyor belt is fixed to the frame via a conveyor belt bracket. The utility model has a simple structure, and a material bag support frame is added to the outside of the feeding barrel, which can effectively prevent fertilizer from falling out during the loading process. The worker only needs to put the fertilizer packaging bag on the material bag support frame and inject fertilizer into the packaging bag through the feeding barrel. The injection amount is controlled by the suction motor. After filling, the conveyor belt transports the fertilizer packaging bag out.

[0004] The aforementioned patent relies on manual bagging to open the packaging bag. However, seaweed fertilizers are often dusty, making it easy to inhale harmful dust during operation. Furthermore, the device lacks an automatic bag-opening mechanism and relies solely on a bag support frame to secure the bag opening. Manual bagging and direct filling cannot ensure the bag opening is fully open, which can easily lead to blockage or leakage. Therefore, an automated device is urgently needed to address these shortcomings. Summary of the Invention

[0010] Preferably, the bag blowing mechanism includes slides respectively installed on both sides of the outer surface of the moving rod, the inner surfaces of the two groups of slides are provided with vacuum negative pressure devices, the upper parts of the two vacuum negative pressure devices are connected to and installed with adsorption tubes, the front ends of the adsorption tubes are respectively connected to and installed with negative pressure suction nozzles, a rotating frame is commonly provided between the two groups of slides, and blowing devices are provided on both sides of the rotating frame.

[0011] Preferably, brackets are provided on both sides of one end of the conveyor, hydraulic cylinders are provided inside the brackets, and a push rod is provided at the telescopic end of the hydraulic cylinder.

When the packaging bag is flatly stuck between the four sets of rotary sleeves, the motor drives the screw rod to rotate, so that the moving rod outside the screw rod can be translated between the two sets of rail racks. The moving rod also drives the slide at the lower end and the vacuum negative pressure device to move to the side of the upper bag rack. The vacuum negative pressure device is adsorbed to the front end of the flat packaging bag through the adsorption tube and the negative pressure suction nozzle, and adsorbs the packaging bag in the nearest position, driving the packaging bag to the side of the discharge pipe. The blowing device at the rotating rack blows diagonally upward to the open part of the packaging bag, causing the inside of the packaging bag to expand, thereby facilitating the bag-holding device to open the inside of the bag body, making it convenient to load fertilizer.

[0015] Through the bag-supporting mechanism, when the inside of the packaging bag is blown open by the blowing device, the two-way telescopic cylinder drives the two sets of sliders to approach each other, causing the annular air-filled bag at the lower end of the fixed rod to squeeze each other, reducing the volume of the annular air-filled bag and penetrating into the interior of the packaging bag. Subsequently, air is inflated into the inflation tube through an external air pump, causing the annular air-filled bag to swell rapidly. The arc-shaped baffles at the corners are attached to the four corners inside the packaging bag to support the packaging bag. In order to ensure the stability of the lower end of the packaging bag, the hydraulic cylinder drives the supporting rods to approach each other and press against the outer surface of the lower end of the packaging bag, making the packaging bag more stable during loading.

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1-8 The automatic quantitative packaging machine for seaweed fertilizer production shown in the figure includes a frame 1, a storage tank 2 is arranged inside the frame 1, and a feeding pipe 10 is connected to the storage tank 2 through a quantitative device arranged inside the frame 1. An L-shaped steel frame 6 is arranged on one side of the frame 1, and a conveyor 9 is arranged on the upper end of the L-shaped steel frame 6. A bag-loading rack 22 is arranged on the upper surface of one side of the L-shaped steel frame 6, and a bag-loading device is arranged inside the bag-loading rack 22. A frame 19 is arranged inside the L-shaped steel frame 6, and rail frames 5 are respectively arranged on both sides of the outer surface of the frame 19. L-shaped platforms 4 are arranged on the upper surfaces of the two groups of rail frames 5, and a bag-supporting device is arranged on the upper part of the L-shaped platform 4.

[0028] The quantitative device includes a suction pump 13 connected and installed at the lower part of the storage tank 2. The suction pump 13 is arranged on the upper surface of the inner side of the frame 1. The end of the suction pump 13 away from the storage tank 2 is connected to the quantitative storage tank 12 through the provided delivery pipe 11. The outside of the quantitative storage tank 12 is fixed to the inner side of the frame 1 through a symmetrically provided frame pipe seat 7. The end of the quantitative storage tank 12 away from the delivery pipe 11 is connected to the discharge pipe 10. The interior of the discharge pipe 10 is connected and a quantitative control valve 21 is installed;

[0029] A weighing sensor can be added inside the quantitative storage tank 12 to accurately control the weight of each unloading and estimate the remaining amount inside the storage tank 2;

[0030] The quantitative control valve 21 can accurately control the filling of fertilizer by presetting the weight of each bag of fertilizer.

[0031] The bag loading device includes an elastic bag clamping mechanism arranged above and below the upper bag rack 22. The elastic bag clamping mechanism includes two sets of folding frames 28 symmetrically installed on one side of the upper bag rack 22. Both sets of folding frames 28 are slidably installed with sliding columns 27 inside. A spring 31 is provided on the outside of the sliding column 27. The two ends of the spring 31 are respectively connected to the end face of the sliding column 27 and the outer wall of the folding frame 28. A clamping column 29 is fixedly provided on the end of the sliding column 27 away from the spring 31, and a roller sleeve 30 is rotatably mounted on the outside of both ends of the clamping column 29.

[0032] The bag-supporting device includes a cylinder 3 arranged above an L-shaped stand 4, a U-shaped frame 35 is fixedly provided at the telescopic end of the cylinder 3, a two-way telescopic cylinder 40 is fixedly provided inside the U-shaped frame 35, and sliders 36 are fixedly provided at both ends of the two-way telescopic cylinder 40. The lower ends of the two groups of sliders 36 are provided with fixed rods 39, and one side of the two fixed rods 39 is provided with a card shell 38. The two groups of card shells 38 are provided with an inflation tube inside. The lower ends of the two inflation tubes are connected together and an annular inflation bag 37 is installed. The corners of the outer wall of the annular inflation bag 37 are provided with baffles 23. The annular inflation bag 37 is located at the front end of the discharge pipe 10;

[0033] When the packaging bag is placed under the front end of the discharge pipe 10, the cylinder 3 drives the U-shaped frame 35 at the lower end to move downward, and the two-way telescopic cylinder 40 drives the two sets of slide blocks 36 to move closer to each other, causing the annular inflatable bag 37 at the lower end of the fixed rod 39 to squeeze each other. After the volume of the annular inflatable bag 37 decreases, it penetrates into the interior of the packaging bag. Then, the external air pump is used to inflate the interior of the inflation tube, which can cause the annular inflatable bag 37 to expand rapidly. The arc-shaped baffles 23 at the corners are attached to the four upper corners of the interior of the packaging bag, thus opening the packaging bag.

[0034] At the same time, the bidirectional telescopic cylinder 40 can be driven to make the annular inflatable bag 37 smaller after the unloading is completed, and part of the fertilizer left on the outside of the annular inflatable bag 37 can fall into the packaging bag, reducing waste.

[0035] The two groups of rail frames 5 are commonly provided with a moving rod 34 inside, and a screw rod 15 is rotatably provided inside one group of rail frames 5. A motor 16 is provided at one end of the screw rod 15. The motor 16 is fixedly arranged on the outside of the corresponding rail frame 5. One end of the moving rod 34 is threadedly connected to the screw rod 15. The end of the moving rod 34 away from the screw rod 15 slides inside the other group of rail frames 5. A bag blowing mechanism is provided on the outer surface of the moving rod 34. After the motor 16 is started, the screw rod 15 is driven to rotate so that the moving rod 34 outside the screw rod 15 can be translated inside the two groups of rail frames 5, driving the bag blowing mechanism to move to one side of the upper bag frame 22. The bag blowing mechanism includes slides 17 respectively installed on both sides of the outer surface of the moving rod 34. The inner surfaces of the two groups of slides 17 are provided with A vacuum negative pressure device 20 is provided. The upper part of the two vacuum negative pressure devices 20 is connected to an adsorption tube 41. The front end of the adsorption tube 41 is connected to a negative pressure suction nozzle 32. A rotating frame 33 is provided between the two sets of slides 17. Both sides of the rotating frame 33 are provided with a blowing device 18. The vacuum negative pressure device 20 can adjust the air pressure to enable the negative pressure suction nozzle 32 to adsorb on the outer surface of one side of the packaging bag, and then move across the upper bag rack 22 to the side of the lower material pipe 10. The blowing device 18 is composed of a gas compressor and a nozzle. By blowing air, it blows air towards the inside of the packaging bag from an upper end of the packaging bag, so that the packaging bag is quickly opened, which facilitates the entry of the annular inflatable bag 37.

[0036] The negative pressure suction nozzle 32 is retractable, and the suction distance can be adjusted to ensure that all the carded packaging bags can be sucked and moved to the lower feed pipe 10. This structure is relatively common, so it will not be described in detail.

[0037] A bracket 8 is provided on both sides of one end of the conveyor 9, and a hydraulic cylinder 14 is provided inside the bracket 8. A push rod 24 is provided at the telescopic end of the hydraulic cylinder 14. The push rod 24 is in an inverted T shape, and a rolling member is provided on the upper part of the push rod 24.

[0038] The hydraulic cylinders 14 can be arranged on both sides by the bracket 8. When the packaging bag is filled above one end of the conveyor 9, the hydraulic cylinders 14 drive the push rods 24 to move closer to each other and press on both sides of the outer surface of the packaging bag to reduce the collapse of the packaging bag and ensure greater stability during filling.

[0039] The rolling member includes a roller rod 25, which is rotatably arranged above the inner part of the support rod 24. Both ends of the outer part of the support rod 24 are provided with arc-shaped support plates 26.

[0040] The bag-stopping plate 26 is an arc-shaped structure that can be pressed against the outer surface of one side of the packaging bag when the fertilizer is filled. The support rod 24 and the bag-stopping plate 26 make the packaging bag more stable and prevent it from collapsing.

[0041] The roller rod 25 rotates in the middle of the T-shaped support rod 24 to cooperate with the negative pressure suction nozzle 32 to absorb one side of the packaging bag and drive the packaging bag to easily pass over the support rod 24.

[0042] Working principle: When in use, workers stack the packaging bags on each other and place them between the four sets of roller sleeves 30. The four sets of roller sleeves 30 are pressed against both sides of the packaging bags under the force of the springs 31. Then the motor 16 is started to drive the screw rod 15 to rotate. The moving rod 34 threadedly connected to the screw rod 15 can move to the side of the upper bag rack 22, prompting the negative pressure suction nozzle 32 to be adsorbed on one side of the packaging bag, and driving the packaging bag to move to the discharge pipe 10. When one side of the packaging bag is adsorbed by the negative pressure suction nozzle 32, the blowing device 18 blows air into the packaging bag at one end obliquely upward, so that the bag mouth opens. At this time, the cylinder 3 drives the U-shaped frame 35 at the lower end to move downward, and the two-way telescopic cylinder 40 drives the bag to move downward. The two sets of sliders 36 are moved closer to each other, causing the annular inflatable bag 37 at the lower end of the fixed rod 39 to squeeze each other. After the volume of the annular inflatable bag 37 decreases, it penetrates into the interior of the packaging bag. Then, air is inflated into the inflation tube through an external air pump, which can cause the annular inflatable bag 37 to swell rapidly. The arc-shaped blocking pieces 23 at the corners are attached to the four corners above the interior of the packaging bag, thus opening the packaging bag. In this way, the discharge pipe 10 can pass through the hollow part inside the annular inflatable bag 37 to fill the interior of the packaging bag with fertilizer. When discharging, the hydraulic cylinder 14 drives the supporting rods 24 to move closer to each other, pressing against the outer surface of the lower end of the packaging bag, so that the packaging bag is more stable when loading above the conveyor 9.

[0043] The fertilizer is extracted from the storage tank 2 by the suction pump 13 and stored in the quantitative storage tank 12. The quantitative control valve 21 is opened and the material is automatically controlled according to the preset packaging weight of the packaging bag, so that the fertilizer loaded in each group of packaging bags is equal in weight. Later, the upper end of the packaging bag is sealed by an external sealing machine, and the conveyor 9 then conveys the packaged packaging bag to the other end. Repeating the above steps can realize automatic bag loading, automatic bag holding, and automatic loading, reducing the problem of personnel absorbing dust during filling and causing physical discomfort.

[0044] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the invention as claimed.
