Description

Technical Field

[0001] This invention relates to the technical field of feed packaging, and more particularly to a rapid pet food packaging device. Background Technology

[0002] In the pet food production and packaging sector, automated feed dispensing is a key step in ensuring product consistency and improving production efficiency. With the booming development of the pet economy, the market is placing higher demands on the accuracy of pet food packaging, product integrity, and production efficiency.

[0003] Currently, most mainstream pet food dispensing devices use quantitative weighing technology based on gravity sensors. By monitoring the weight of the material inside the packaging bag in real time, the sensor transmits a signal to the controller when a preset value is reached. The controller then instructs the actuator to close the discharge port, thereby achieving quantitative dispensing. However, this technology has revealed significant technical shortcomings in practical applications:

[0004] 1. Due to unavoidable delays in signal acquisition, data processing, controller response, and electric valve operation, even if the sensor immediately issues a stop signal after detecting the target weight, the discharge port will continue to discharge feed for a short time difference, causing the actual weight of each bag of finished product to exceed the set value. Although the difference in a single instance is small, the cumulative effect of this systemic overweight phenomenon is significant in large-scale continuous production. It not only wastes raw materials but also directly increases production costs and affects the economic benefits of enterprises.

[0005] 2. Existing dispensing devices mostly use movable valve plates or rotary dispensing wheels as blocking mechanisms. During the rapid closing process, feed particles, especially loosely structured and brittle extruded grains and coated grains, are prone to breakage, flaking, or even pulverization under local high pressure and severe shearing force. This not only reduces the product integrity rate and affects the appearance quality and consumer experience, but also generates a large amount of dust that pollutes the equipment, increases the difficulty of cleaning, and may cause safety hazards, such as the risk of dust explosion. Summary of the Invention

[0006] In view of this, the present invention provides a rapid pet food dispensing device that overcomes the disadvantages of existing dispensing devices, which cause the actual weight of each package to exceed the set value, resulting in higher production costs and reduced feed integrity.

[0007] The technical solution of the present invention is as follows: a rapid pet food dispensing device, comprising: a support frame; a gravity sensor mounted on the support frame; a controller mounted on the side of the support frame; a hopper connected to the support frame; a mounting frame connected to the bottom of the hopper; an air supply pipe connected to the support frame; a return pipe connected to the side of the hopper and maintaining communication; a first electric push rod symmetrically mounted on the inner side of the mounting frame; a lifting frame connected to the telescopic rod of the first electric push rod, with the end of the air supply pipe maintaining communication with the side of the lifting frame and the lower end of the return pipe maintaining communication with the top of the lifting frame; a rotating pipe rotatably connected to the lifting frame; a filter plate connected to the inner side of the rotating pipe; a rotating assembly disposed on the lifting frame for driving the rotating pipe to rotate; a control assembly disposed on the rotating pipe for controlling the suction force inside the rotating pipe; and a material blocking assembly disposed at the bottom of the hopper for blocking the feed.

[0008] As a preferred embodiment of the present invention, the rotating assembly includes: a first motor mounted on a lifting frame; a driving gear connected to the output shaft of the first motor; and a driven gear ring connected to the rotating tube, wherein the driven gear ring meshes with the driving gear.

[0009] As a preferred embodiment of the present invention, the control component includes: a second motor mounted on a rotating tube; a fixed ring connected to the inner side of the rotating tube; a first baffle circumferentially spaced and connected to the inner side of the fixed ring; and a second baffle circumferentially spaced and connected to the output shaft of the second motor, wherein the bottom of the second baffle contacts the top of the first baffle, and the second baffle and the first baffle completely overlap in the vertical direction.

[0010] As a preferred embodiment of the present invention, the material blocking component includes: a discharge pipe connected to the bottom of the hopper and kept in communication; an annular airbag installed inside the discharge pipe; a flow interception mechanism disposed inside the discharge pipe for pre-intercepting the feed; and an air blowing mechanism disposed inside the discharge pipe for blowing the feed inside the discharge pipe upward.

[0011] As a preferred embodiment of the present invention, the interception mechanism includes: a second electric push rod, rotatably mounted on the inner side of the discharge pipe; a rotating baffle, rotatably connected to the inner side of the discharge pipe, and the telescopic rod of the second electric push rod is rotatably connected to the bottom of the rotating baffle; a fixed baffle, connected to the inner side of the discharge pipe; and a corrugated pipe, sleeved on the outer side of the telescopic rod of the second electric push rod.

[0012] As a preferred embodiment of the present invention, the air blowing mechanism includes: an air jet pipe connected to the discharge pipe; and a photoelectric sensor installed on the inner side of the discharge pipe.

[0013] As a preferred embodiment of the present invention, it further includes: a geared motor, installed on the top of the silo; and a stirring rod, rotatably connected inside the silo, with the rotation shaft of the stirring rod connected to the output shaft of the geared motor.

[0014] As a preferred embodiment of the present invention, it further includes: a scale plate connected to the side of the hopper.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a rotating tube, filter plate, control components and return tube to cooperate to accurately suck up the overweight feed in the packaging bag by using the negative pressure state of the rotating tube. The second motor drives the second baffle to rotate relative to the first baffle, gradually reducing the suction force of the rotating tube, so that the feed slowly falls back into the packaging bag. With the real-time monitoring of the gravity sensor, the weight error of each bag of feed can be controlled within one feed, effectively solving the overweight problem caused by system delay in the prior art, reducing raw material waste and production costs.

[0016] 2. This invention employs a flow-blocking mechanism consisting of a rotating baffle and a fixed baffle driven by a second electric push rod, in conjunction with an air-blowing mechanism consisting of an annular airbag and a jet pipe. When the target weight is reached, the rotating baffle and the fixed baffle first perform flexible flow blocking, then the jet pipe blows air upwards to suspend the feed and prevent it from falling. Finally, the annular airbag expands to completely seal the discharge pipe, achieving rapid and gentle blocking of the feed. This greatly reduces the breakage, flaking, and pulverization of feed particles during the packaging process, ensuring product integrity and reducing dust pollution and safety hazards.

[0017] 3. This invention uses a geared motor to drive a stirring rod to continuously stir the feed in the hopper, effectively preventing feed from accumulating and clogging in the hopper, and ensuring the continuity and stability of the discharge. At the same time, the transparent scale plate allows staff to intuitively monitor the remaining feed in the hopper, facilitating timely replenishment and further improving the automation level and production efficiency of the entire packaging process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example: A rapid pet food dispensing device, such as Figures 1-7As shown, the system includes a support frame 1, a gravity sensor 101, a controller 2, a hopper 3, a mounting frame 4, an air supply pipe 5, a return pipe 6, a first electric push rod 7, a lifting frame 8, a rotating pipe 9, a filter plate 10, a rotating assembly, a control assembly, and a material blocking assembly. The gravity sensor 101 is mounted on the lower part of the support frame 1. The controller 2 is mounted on the lower front side of the support frame 1. The hopper 3 is connected to the support frame 1 and is located directly above the gravity sensor 101. The mounting frame 4 is connected to the bottom of the hopper 3, and a vertical hole is opened in the middle of the right side of the mounting frame 4. The air supply pipe 5 is connected to the lower right side of the support frame 1. The air supply pipe 5 is a flexible hose, and the middle section of the air supply pipe 5 has a telescopic corrugated structure. The return pipe 6 is connected to the upper right side of the hopper 3 and remains connected. 6 is also a flexible hose, and the lower part of the return pipe 6 is also a telescopic corrugated structure. Both the air supply pipe 5 and the return pipe 6 pass through the vertical holes on the side of the mounting frame 4. The first electric push rod 7 is symmetrically installed on the right side of the inner wall of the mounting frame 4. The telescopic rods of the two first electric push rods 7 are connected to the lifting frame 8. The lower end of the air supply pipe 5 is connected to the right side of the lifting frame 8 and keeps in communication. The lower end of the return pipe 6 is connected to the top of the lifting frame 8 and keeps in communication. A rotating pipe 9 is rotatably connected to the lifting frame 8. A filter plate 10 is connected to the inner side of the rotating pipe 9. The lifting frame 8 is equipped with a rotating component for driving the rotating pipe 9 to rotate. The rotating pipe 9 is equipped with a control component for controlling the magnitude of its internal suction. The bottom of the hopper 3 is equipped with a material blocking component for blocking the feed.

[0029] like Figure 4 As shown, the rotating assembly includes a first motor 11, a driving gear 12, and a driven gear ring 13. The first motor 11 is installed on the upper right side of the lifting frame 8. The driving gear 12 is connected to the output shaft of the first motor 11. The driven gear ring 13 is connected to the upper right side of the rotating tube 9, and the driven gear ring 13 meshes with the driving gear 12.

[0030] like Figure 4 and Figure 5 As shown, the control assembly includes a second motor 14, a fixing ring 15, a first baffle 16, and a second baffle 17. The second motor 14 is mounted on the top of the rotating tube 9, and the fixing ring 15 is connected to the inner side of the rotating tube 9. The fixing ring 15 is located above the filter plate 10. Three first baffles 16 are circumferentially spaced on the inner side of the fixing ring 15, with a gap between two adjacent first baffles 16. Three second baffles 17 are circumferentially spaced on the output shaft of the second motor 14. The bottom of the second baffle 17 contacts the top of the first baffle 16, and the second baffle 17 and the first baffle 16 completely overlap in the vertical direction.

[0031] like Figure 6 and Figure 7As shown, the material blocking assembly includes a discharge pipe 18, an annular airbag 19, a flow interception mechanism, and an air blowing mechanism. The bottom of the hopper 3 is connected to and maintains communication with the discharge pipe 18. The discharge pipe 18 is located inside the mounting frame 4. An annular airbag 19 is installed on the lower inner side of the discharge pipe 18. A flow interception mechanism for pre-intercepting the feed is provided inside the discharge pipe 18. An air blowing mechanism for blowing the feed inside the discharge pipe 18 upwards is also provided inside the discharge pipe 18. The flow interception mechanism includes a second electric push rod 20, a rotating baffle 21, a fixed baffle 22, and a corrugated pipe 23. The second electric push rod 20 is rotatably installed on the middle front side of the inner wall of the discharge pipe 18. A rotating baffle 21 is rotatably connected to the upper front side of the inner wall of the discharge pipe 18. The telescopic rod of push rod 20 is rotatably connected to the bottom of rotating baffle 21. A fixed baffle 22 is connected to the upper rear side of the inner wall of discharge pipe 18. A corrugated pipe 23 is sleeved on the outer side of the telescopic rod of the second electric push rod 20. The two ends of the corrugated pipe 23 are respectively connected to the cylinder body of the second electric push rod 20 and the end of the telescopic rod. The corrugated pipe 23 can extend and retract synchronously with the telescopic rod of the second electric push rod 20. The corrugated pipe 23 can prevent the telescopic rod of the second electric push rod 20 from contacting the feed. The air blowing mechanism includes an air jet pipe 24 and a photoelectric sensor 25. The air jet pipe 24 is connected to the middle of the discharge pipe 18. The photoelectric sensor 25 consists of a receiver and a transmitter. The receiver and transmitter are respectively installed on the lower front and rear sides of the inner wall of the discharge pipe 18.

[0032] Initially, the rotating baffle 21 is in a downward-rotating open state. When the device is needed, first install it in the designated position, then connect the upper end of the air supply pipe 5 to a reversible air pump, connect the annular airbag 19 to a reversible air pump, and connect the jet pipe 24 to a blower pump. Then, control the reversible air pump through the controller 2 to inject air into the annular airbag 19, causing the annular airbag 19 to expand and close, blocking the lower end of the discharge pipe 18. Then, put an appropriate amount of feed into the hopper 3. Some of the feed inside the hopper 3 will fall into the discharge pipe 18 due to its weight. The packaging bag is placed on top of the gravity sensor 101. The controller 2 then controls a reversible air pump to extract air from the annular airbag 19, causing it to contract and open. At this time, the feed in the discharge pipe 18 can pass through the inside of the annular airbag 19 and fall into the packaging bag. The gravity sensor 101 can detect the weight of the feed in the packaging bag in real time. When the weight of the feed in the packaging bag reaches a set value, the gravity sensor 101 sends a signal. Upon receiving the signal, the controller 2 controls the second electric push rod 20 to drive the rotating baffle 21 to rotate upwards and close. Once the rotating baffle 21 is fully closed... A certain gap remains between the rotating baffle 21 and the fixed baffle 22 to prevent the feed from breaking under pressure. The rotating baffle 21 and the fixed baffle 22 act as interceptors, allowing only a small amount of feed to pass through the gap and fall down into the packaging bag through the inner side of the annular airbag 19. Then, the controller 2 controls the air pump to deliver air to the jet pipe 24, causing the jet pipe 24 to spray air upwards, thus blowing the feed that has passed through the gap upwards. This keeps the feed suspended above the annular airbag 19, preventing it from falling further into the annular airbag 19. The controller 2 will control the photoelectric sensor 25 to start working. The photoelectric sensor 25 is used to detect the feeding status of the feed. When the photoelectric sensor 25 detects that no feed is falling to the inside of the annular airbag 19, the photoelectric sensor 25 will send a signal. After receiving the signal, the controller 2 will control the reversible air pump to inject air into the annular airbag 19, causing the annular airbag 19 to expand and close. Then the controller 2 will control the photoelectric sensor 25 to stop working and control the jet pipe 24 to stop jetting upwards. The controller 2 will also control the second electric push rod 20 to drive the rotating baffle 21 to rotate downwards and open.At this point, the actual weight of the feed inside the packaging bag will definitely exceed the set value (with an error of about 5g). Controller 2 will control the first electric push rod 7 to drive the lifting frame 8 downwards. The lifting frame 8 will drive the rotating tube 9 downwards, so that the bottom of the rotating tube 9 is close to the surface of the feed inside the packaging bag. Then, controller 2 will control the reversible air pump to draw air from the rotating tube 9 through the air supply pipe 5, creating a negative pressure state inside the rotating tube 9. The rotating tube 9 can then draw in some of the feed (approximately 10g) from the packaging bag. The filter plate 10 is used to block and limit the feed inside the rotating tube 9, preventing the feed from entering the air supply pipe 5. Since the amount of feed drawn away by the rotating tube 9 is greater than the error amount when the feed is discharged, the actual weight of the feed inside the packaging bag at this point will definitely exceed the set value (with an error of about 5g). If the weight of the feed in the rotating tube 9 falls below the set value, the controller 2 will control the second motor 14 to drive the second baffle 17 to rotate slowly, gradually reducing the overlapping area of ​​the second baffle 17 and the first baffle 16 in the vertical direction. The second baffle 17 will block the gap between two adjacent first baffles 16, and the area blocked by the second baffle 17 will gradually increase, thereby gradually reducing the suction force of the rotating tube 9, so that the feed in the rotating tube 9 will gradually fall back into the packaging bag. When the gravity sensor 101 detects that the weight of the feed in the packaging bag reaches the set value, the gravity sensor 101 will send a signal. After receiving the signal, the controller 2 will control the second motor 14 to stop working, so that the second baffle 17 stops rotating. At this time, the feed in the rotating tube 9 will not... The feed then falls into the packaging bag, and the weight of the feed inside the bag deviates from the set value by approximately the weight of one feed pellet, which is negligible. Then, controller 2 controls the first electric push rod 7 to drive the lifting frame 8 upwards to reset. The lifting frame 8 drives the rotating tube 9 upwards to reset. Subsequently, controller 2 controls the first motor 11 to drive the drive gear 12 to rotate. The drive gear 12 drives the driven gear ring 13 to rotate 180 degrees, which in turn drives the rotating tube 9 to rotate 180 degrees, aligning the end of the rotating tube 9 with the end of the return tube 6. Then, controller 2 controls the second motor 14 to drive the second baffle 17 to reverse and reset, ensuring that the second baffle 17 and the first baffle 16 are completely aligned vertically. Finally, controller 2 controls the reversible air pump to... Compressed air is injected into the rotating pipe 9 through the air supply pipe 5, which blows the feed in the rotating pipe 9 upwards to the return pipe 6, allowing the feed to return to the hopper 3. This achieves the purpose of recovering excess feed. During the feed recovery process, workers can remove the packaged bags containing feed and place the next packaged bag on top of the gravity sensor 101 to collect the next batch of feed. After the feed recovery is completed, the controller 2 will control the first motor 11 to drive the drive gear 12 to reverse. The drive gear 12 drives the driven gear ring 13 to reverse 180 degrees to reset, and the driven gear ring 13 drives the rotating pipe 9 to reverse 180 degrees to reset. Through the above cycle, the integrity rate of the feed can be improved and the production cost can be reduced.

[0033] like Figure 8As shown, it also includes a geared motor 26 and a stirring rod 27. The geared motor 26 is installed on the top of the hopper 3, and the stirring rod 27 is rotatably connected to the middle of the inner top of the hopper 3. The upper end of the rotating shaft of the stirring rod 27 is connected to the output shaft of the geared motor 26. When the device is in use, the geared motor 26 can be controlled by the controller 2 to drive the stirring rod 27 to rotate. The stirring rod 27 can stir the feed in the hopper 3 to prevent the feed in the hopper 3 from accumulating and clogging.

[0034] like Figure 8 As shown, it also includes a scale plate 28. The scale plate 28 is connected to the front side of the feed hopper 3. The scale plate 28 is made of transparent material. By looking at the scale on the scale plate 28, the staff can detect the remaining amount of feed in the feed hopper 3 in real time so that the feed can be replenished into the feed hopper 3 in a timely manner.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
