Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed production and packaging technology, and in particular to a feed packaging machine that prevents leakage. Background Technology
[0002] Feed packaging machines are key equipment in the feed production and processing process. They consist of a feeding system, a metering device, a packaging actuator, and a control system. They can quantitatively fill feed products that have undergone crushing, mixing, and pelleting into woven bag-type packaging containers according to preset weight standards and complete the sealing operation. They are important equipment connecting feed production, storage, and transportation.
[0003] Feed packaging machines can replace traditional manual packaging operations in the feed industry, significantly reducing the intensity of manual labor and lowering labor costs. Through precise measurement and a stable packaging process, they can also ensure that the weight of each bag of feed is consistent, avoiding the problem of inconsistent packaging specifications caused by human operation errors. At the same time, they can speed up the process of feed from production to storage and distribution, ensuring that feed products can quickly respond to market demands and improve the overall production efficiency of enterprises.
[0004] Currently, mainstream feed packaging machines on the market focus on improving feeding and packaging efficiency by optimizing feeding speed and shortening metering cycles to achieve higher packaging output per unit time. However, they have shortcomings in the design to prevent leakage and scattering during the feed packaging process. When feed is fed from the feeding system into the packaging container, some feed may leak out of the equipment due to misalignment between the feeding port and the packaging container, or the high fluidity of the feed particles. Under the impact of feeding, fine feed dust will be scattered into the surrounding air environment. The leaked feed is difficult to recycle, resulting in waste of feed resources and increased production costs for enterprises. The scattered dust not only pollutes the air environment in the workshop but also affects the respiratory health of operators, failing to meet the environmental protection and safety requirements of modern feed production. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a feed packaging machine that prevents leakage, aiming to improve the existing technology that focuses on feeding and packaging efficiency but neglects the problems of preventing leakage and feed spillage during feeding.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-4 An embodiment of this utility model is provided: a feed packaging machine with leak-proof material, including a hydraulic push block 1, a heating strip 2 is provided on the front side of the hydraulic push block 1, a leak-proof material feeding mechanism 3 is provided on the top of the hydraulic push block 1, the leak-proof material feeding mechanism 3 is used to prevent material leakage and feed spillage during loading, and a heat shrinking mechanism 4 is provided at the bottom of the heating strip 2, the heat shrinking mechanism 4 is used to quickly heat shrink the mouth of the feed packaging bag. The anti-leakage feeding mechanism 3 includes a side rotating connector 31. The front side of the side rotating connector 31 is fixedly connected to the rear side of the hydraulic push block 1. A side extension frame 32 is fixedly connected to the rear side of the side rotating connector 31. A side connecting rod 33 is fixedly connected to the left side of the side extension frame 32. A bottom extension frame 34 is rotatably connected to the bottom of the side connecting rod 33. A bottom extension ring 35 is fixedly connected to the bottom of the bottom extension frame 34. An anti-escape component 36 is provided on the outside of the bottom extension ring 35. An upper feeding component 37 is provided on the top of the side extension frame 32. Specifically, when the device enters the feed packaging operation stage, the anti-leakage feeding mechanism 3 is activated to ensure that there is no leakage or spillage during the feeding process. The side rotating connector 31, through its fixed connection with the rear side of the hydraulic push block 1, provides a stable installation foundation for the side extension frame 32, so that the side extension frame 32 can maintain structural stability in subsequent operations. The hydraulic push block 1 injects hydraulic oil into the cylinder through a hydraulic pump to push the piston and push rod to extend for linear movement, with a stroke of 50-100 mm. The side extension frame 32, through its fixed connection with the side connecting rod 33, transmits the force to the side connecting rod. The connecting rod 33 causes the side connecting rod 33 to drive the bottom extension frame 34, which is rotatably connected at the bottom, to adjust its angle. During the movement, the bottom extension frame 34 drives the bottom extension ring 35, which is fixedly connected at the bottom, to move synchronously. The bottom extension ring 35 directly acts on the opening of the feed packaging bag, opening the bag and providing a suitable channel for subsequent feed input. At the same time, the anti-escape component 36 set on the outside of the bottom extension ring 35 also plays a role, blocking the feed dust generated during the feeding process and preventing the feed from escaping to the outside of the device, thus ensuring the sealing and safety of the entire feeding process. The upper feeding component 37 in the anti-leakage feeding mechanism 3 is set on the top of the side expansion frame 32. After the bottom expansion ring 35 opens the bag opening, the upper feeding component 37 can stably transport the feed to be packaged into the bag. During the transportation process, it cooperates with the bottom expansion ring 35 and the anti-escape component 36. The discharge port of the upper feeding component 37 is precisely connected with the bag opening opened by the bottom expansion ring 35, further reducing the spillage of feed during transportation. The anti-escape component 36 completely blocks the dust generated during feed transportation, ensuring that the upper feeding component 37 can efficiently transport feed without causing feed waste or environmental dust pollution. The side extension frame 32 serves as the core support structure of the anti-leakage feeding mechanism 3. In addition to connecting the side rotating connector 31 and the side connecting rod 33, it also provides an installation carrier for the upper feeding assembly 37. This allows the upper feeding assembly 37, the side connecting rod 33, and the side rotating connector 31 to form a unified working unit under the integration of the side extension frame 32. When the side rotating connector 31 drives the side extension frame 32 to adjust its position, the upper feeding assembly 37 and the side connecting rod 33 can move synchronously to ensure the consistency of the actions of each component. This avoids the problem of the packaging bag opening not being able to be accurately coordinated with the feed delivery due to asynchronous component actions, thus ensuring the overall working efficiency and stability of the anti-leakage feeding mechanism 3.
[0024] Reference Figures 1-5The heat shrinking mechanism 4 includes an upper shell 41, the bottom of which is fixedly connected to the top of the heating strip 2. A rear locking key 42 is fixedly connected to the rear bottom of the upper shell 41. Inner reinforcing keys 43 are fixedly connected to the left and right bottom sides of the upper shell 41. A push-pull connecting rod 44 is fixedly connected to the front bottom of the upper shell 41. A lower shell 45 is rotatably connected to the bottom of the upper shell 41. A lower locking assembly 46 is provided on the top of the lower shell 45. Specifically, after the feed feeding operation is completed, the heating strip 2 and the heat shrinking mechanism 4 work together to quickly press and fix the bag opening. The heating strip 2 is 700 mm long. During the heating process, the heating strip is quickly heated to a suitable temperature by the internal heating wire to ensure that the bag opening material is softened and effectively fused. The heating strip 2 is located in front of the hydraulic push block 1 and can reach a suitable working position with the assistance of the hydraulic push block 1. It provides the required heat for pressing the bag opening through its own heating function. The bottom of the upper shell 41 of the heat shrinking mechanism 4 is fixedly connected to the top of the heating strip 2, so that the upper shell 41 can move synchronously with the position adjustment of the heating strip 2. This ensures that the heat shrinking mechanism 4 and the heating strip 2 always maintain a suitable working position relationship, providing a basis for the subsequent bag opening heat shrinking operation. The rear locking key 42, which is fixedly connected to the bottom rear side of the upper shell 41, can engage with other compatible structures of the device during the operation of the heat shrink mechanism 4, thereby enhancing the stability of the upper shell 41 after installation and preventing displacement of the upper shell 41 during heat shrinking operation. The inner reinforcing key 43, which is fixedly connected to the left and right sides of the bottom of the upper shell 41, can improve the structural strength of the upper shell 41 itself, prevent the upper shell 41 from deforming due to the force generated by the heat shrinking operation over a long period of time, and ensure the durability of the overall structure of the heat shrink mechanism 4. The push-pull connecting rod 44, which is fixedly connected to the bottom front side of the upper shell 41, can provide a force point when the position of the lower shell 45 needs to be adjusted. The operator can adjust the angle of the lower shell 45, which is rotated and connected to the bottom of the upper shell 41, by manipulating the push-pull connecting rod 44, so that the lower shell 45 can accurately align with the heat-shrinkable area of the packaging bag opening. The lower locking component 46 set on the top of the lower shell 45 can lock with the side fitting structure of the upper shell 41 during the heat-shrinking operation, fixing the relative position of the lower shell 45 and the upper shell 41, ensuring that the heat-shrinking mechanism 4 exerts a uniform and stable heat-shrinking force on the packaging bag opening, realizing the rapid sealing of the packaging bag opening, and completing the entire feed packaging process. Both the heat shrink mechanism 4 and the heating strip 2 are easy to disassemble and assemble. When the heat shrink mechanism 4 needs to be repaired and maintained after long-term use, the heat shrink mechanism 4 can be directly removed from the device without disassembling the overall structure of the device, which greatly reduces the difficulty and time cost of maintenance and ensures that the device can operate stably for a long time. The upper shell 41 of the heat shrinking mechanism 4 is fixedly connected to the heating strip 2, allowing some of the heat generated by the heating strip 2 to be transferred to the upper shell 41, thus helping to increase the internal temperature of the heat shrinking mechanism 4 and accelerate the heat shrinking speed of the packaging bag opening. The lower shell 45, which is rotatably connected to the bottom of the upper shell 41, can be adjusted at an angle to adapt to the opening of packaging bags of different thicknesses, ensuring that the lower shell 45 can fully contact the opening of the packaging bag and evenly apply the heat shrinking force to the bag opening area. The locking component 46 at the top of the lower shell 45 engages with the upper shell 41 to prevent the lower shell 45 from shifting due to vibration during the heat shrinking process, ensuring the stability of the heat shrinking operation and avoiding insufficient heat shrinking of the bag opening in some areas. The push-pull connecting rod 44 at the bottom of the upper shell 41 also plays a role in the disassembly and assembly of the heat shrinking mechanism 4. Operators can easily move the upper shell 41 by pushing and pulling the connecting rod 44, reducing the difficulty of disassembling and assembling the heat shrinking mechanism 4.
[0025] Reference Figures 1-2 The anti-escape assembly 36 includes an anti-escape ring 361, the inner wall of which is disposed on the outer wall of the bottom expansion ring 35. A reinforcing ring 362 is fixedly connected to the outer wall of the anti-escape ring 361. The upper feeding assembly 37 includes an inlet 371, the bottom of which is disposed on the top of the side expansion frame 32. Side quick-release pieces 372 are fixedly connected to both the left and right sides of the inlet 371. The lower locking assembly 46 includes a lower locking key 461, the bottom of which is fixedly connected to the lower shell 4. At the top of 5, a lower hot pressing block 462 is fixedly connected to the top of the lower locking key 461. An upper feeding port 5 is provided at the top of the hydraulic push block 1. An opening and closing rotary knob 6 is rotatably connected to the right side of the upper feeding port 5. A lower connecting frame 7 is fixedly connected to the bottom of the upper feeding port 5. An upper connecting frame 8 is provided at the bottom of the lower connecting frame 7. A main sliding frame 9 is fixedly connected to the bottom of the upper connecting frame 8. A conveyor bed 10 is fixedly connected to the bottom of the main sliding frame 9. A rotary motor 11 is fixedly connected to the rear right side of the conveyor bed 10. Specifically, when the device enters the feed packaging operation stage, the anti-leakage feeding mechanism 3 is activated to ensure that there is no leakage or spillage during the feeding process. The side rotating connector 31, through its connection with the rear side of the hydraulic push block 1, provides a stable installation foundation for the side expansion frame 32, enabling the side expansion frame 32 to maintain structural stability during subsequent operations. The side expansion frame 32, through its connection with the side connecting rod 33, transmits force to the side connecting rod 33, causing the side connecting rod 33 to drive the bottom rotating connection of the bottom expansion frame 34 to adjust its angle. During the movement, the bottom expansion frame 34 drives the bottom connecting bottom expansion ring 35 to move synchronously. The bottom expansion ring 35 directly acts on the opening of the feed packaging bag. The packaging bag is opened to provide a suitable channel for subsequent feed input. At the same time, the anti-escape component 36 set on the outside of the bottom expansion ring 35 plays a role. The inner wall of the anti-escape ring 361 in the anti-escape component 36 is attached to the outer wall of the bottom expansion ring 35 and can move synchronously with the bottom expansion ring 35 to block the feed dust generated during the feeding process. The reinforcing ring 362 fixedly connected to the outer wall of the anti-escape ring 361 enhances the structural strength of the anti-escape ring 361 and prevents the anti-escape ring 361 from deforming during long-term use. This ensures that the anti-escape component 36 continues to play a blocking role, preventing feed from escaping to the outside of the device and ensuring the sealing and safety of the entire feeding process. The upper feeding component 37 in the anti-leakage feeding mechanism 3 is set on the top of the side expansion frame 32. The bottom of the feeding port 371 of the upper feeding component 37 is installed on the top of the side expansion frame 32. After the bottom expansion ring 35 opens the bag opening, the feeding port 371 can receive the feed conveyed from the upper feeding port 5 and stably convey the feed into the bag. The side quick-release parts 372 fixedly connected to the left and right sides of the feeding port 371 make it easy to quickly remove the feeding port 371 from the side expansion frame 32 in case of failure, which is convenient for maintenance. During the conveying process, the feeding port 371 cooperates with the bottom expansion ring 35 and the anti-escape component 36. The discharge port of the feeding port 371 is precisely connected with the bag opening of the bag opened by the bottom expansion ring 35, further reducing the spillage of feed during the conveying process. The anti-escape component 36 completely blocks the dust generated during the conveying of feed, ensuring that the upper feeding component 37 does not cause feed waste or environmental dust pollution while conveying feed.
[0026] Working principle: When this leak-proof feed packaging machine is working, the feed packaging bag is first placed in the designated position. Then, the leak-proof feeding mechanism 3 is started. Through the coordinated action of the side rotating connector 31, the side expansion frame 32, the side connecting rod 33, and the bottom expansion frame 34, the bottom expansion ring 35 is driven to open the bag opening. The anti-escape component 36 simultaneously plays a blocking role. Then, the external feed is conveyed into the packaging bag through the upper feeding component 37. After the feeding is completed, the heating strip 2 and the heat shrinking mechanism 4 cooperate to heat seal the bag opening. After the sealing is completed, the relevant components are reset, waiting for the next packaging operation. The whole process achieves the goal of preventing feed leakage, preventing escape, and efficient packaging through the orderly operation of each component. The side expansion frame 32 is stably supported by the side rotation connector 31 and the fixed connection on the rear side of the hydraulic push block 1. The side expansion frame 32 drives the side connecting rod 33 fixed on the left side to move. The side connecting rod 33 drives the bottom expansion frame 34 rotatably connected at the bottom to adjust the angle. The bottom expansion frame 34 drives the bottom expansion ring 35 fixed at the bottom to open the bag opening. At the same time, the anti-escape component 36 on the outside of the bottom expansion ring 35 moves synchronously with the bottom expansion ring 35. The anti-escape ring 361 in the anti-escape component 36 fits against the outer wall of the bottom expansion ring 35 to block dust and scattered feed. The reinforcing ring 362 strengthens the anti-escape ring 361 to prevent deformation. The side quick-release part 372 facilitates the maintenance and replacement of the feed inlet 371. All components work together to form a closed feeding environment. This process effectively prevents feed from leaking and escaping to the outside during feeding, reduces feed waste, avoids dust pollution of the workshop environment, and protects the respiratory health of operators. At the same time, the convenient maintenance of the feed inlet 371 reduces equipment downtime for maintenance and improves the efficiency of continuous equipment operation. The heating strip 2, located on the front side of the hydraulic pusher 1, adjusts its distance from the bag opening under the push-pull action of the hydraulic pusher 1, ensuring that the heating strip 2 maintains a suitable contact state with the bag opening. In the heat shrinking mechanism 4, which is fixedly connected to the top of the heating strip 2, the rear locking key 42 on the bottom rear side of the upper shell 41 and the lower locking key 461 of the lower locking assembly 46 on the top of the lower shell 45 engage and fix the shell when it is closed. The lower heat pressing block 462 on the top of the lower locking key 461 works with the heating strip 2 to enhance the heat pressing effect. The inner reinforcing keys 43 on the left and right sides of the bottom of the upper shell 41 enhance the strength of the upper shell 41 to prevent deformation. The push-pull connecting rod 44 on the front side of the bottom of the upper shell 41 allows the operator to control the lower shell 45 to rotate around the upper shell 41 to open and close. This process enables the rapid heat sealing and fixing of the bag opening, ensuring a tight seal and preventing feed leakage during subsequent transportation and storage. At the same time, the structural design of each component of the heat shrinking mechanism 4 facilitates quick disassembly and maintenance by the operator, reducing the difficulty and cost of equipment maintenance and ensuring the efficient and continuous operation of the packaging process. External feed is received by the upper feeding port 5 at the top of the hydraulic pusher block 1 and guided to the feed inlet 371. The opening and closing knob 6 connected to the right side of the upper feeding port 5 adjusts the opening and closing degree of the internal channel to control the feed conveying speed. The lower connecting frame 7 fixedly connected to the bottom of the upper feeding port 5 cooperates with the upper connecting frame 8 to support the upper feeding port 5. The main sliding frame 9 fixedly connected to the bottom of the upper connecting frame 8 drives the upper feeding port 5 to adjust its position to accurately align with the feed inlet 371. The bottom extension frame 34 is rotatably connected to the side connecting rod 33, and its angle can be adjusted according to the size of the bag opening, thereby driving the bottom extension ring 35 to change the opening range. This process realizes the control of feed conveying speed to avoid blockage of the feed inlet 371 and feed accumulation and overflow in the bag, ensuring that there is no spillage in the feed conveying path. At the same time, the equipment can be adapted to different specifications of feed packaging bags without the need to replace special components, which improves the adaptability of the equipment to different packaging needs, reduces the cost of replacing components for enterprises, and enhances the flexibility of equipment use. The feed packaging bags are carried by the conveyor bed 10 fixedly connected to the bottom of the main sliding frame 9. After feeding and heat sealing of the bag opening, the rotary motor 11 fixedly connected to the right rear side of the conveyor bed 10 provides power to the conveyor bed 10, driving the conveyor bed 10 to move and transfer the packaged feed bags to the next process position. At the same time, the hydraulic push block 1 coordinates the action rhythm of feeding and heat sealing by adjusting the relative position of the heating strip 2 and the anti-leakage feeding mechanism 3. This process realizes the automatic transfer of packaged feed bags, replacing manual handling, reducing the labor intensity of operators, reducing labor costs, and ensuring the continuous operation of the entire packaging process from feeding, heat sealing to transfer, avoiding the connection between each link, greatly improving the overall efficiency of feed packaging, and meeting the beneficial effects of meeting the needs of large-scale production of enterprises. The side expansion frame 32 serves as the core support of the leak-proof feeding mechanism 3, connecting the side rotating connector 31, the side connecting rod 33, and the upper feeding assembly 37, forming a unified working unit. When the side rotating connector 31 moves the side expansion frame 32 to adjust its position, the upper feeding assembly 37 and the side connecting rod 33 move synchronously. The side connecting rod 33 avoids deformation and breakage due to its own structural strength when transmitting force. The side rotating connector 31 adjusts the rotation angle of the side expansion frame 32 as needed to ensure that the bottom expansion ring 35 opens the bag opening from the appropriate angle. This process ensures that the actions of each component are consistent, avoiding the inaccurate coordination between the opening of the packaging bag and the feed delivery due to asynchronous actions. This ensures the overall working efficiency and stability of the leak-proof feeding mechanism 3. At the same time, the structural strength of each component ensures that the equipment is not easily damaged during long-term use, extending the service life of the equipment and reducing the overall cost of equipment replacement and maintenance for enterprises.
