Description

Technical Field

[0001] This utility model relates to the field of food packaging equipment technology, and in particular to a dual-station high-efficiency multi-functional beef vacuum packaging machine. Background Technology

[0002] In the beef processing and sales industry, vacuum packaging is a key step in ensuring the freshness of beef, extending its shelf life, and improving the appearance and quality of the product. However, existing beef vacuum packaging machines have a series of problems that need to be improved in practical applications. Most traditional vacuum packaging machines adopt a single-station design, which can only vacuum package one portion of beef at a time. The packaging efficiency is low and it is difficult to meet the needs of large-scale production and the market for rapid packaging. Especially during the peak sales season, the capacity bottleneck problem becomes more and more prominent.

[0003] A search revealed Chinese Publication No. CN214139089U, which discloses a quantitative vacuum packaging mechanism for a beef packaging machine. The mechanism includes a machine base and a column. The column is fixedly mounted on the upper surface of the machine base. A weighing mechanism is located on one side of the column, and a conveyor belt is located on one side of the weighing mechanism. A fixed frame is fixedly mounted on one side of the conveyor belt. A vacuum chamber is located inside the fixed frame, and a packaging mechanism is located inside the vacuum chamber. A moving mechanism is located below the packaging mechanism on the inner wall of the fixed frame. This invention ensures consistent weight distribution of packaged beef through the weighing mechanism, preventing uneven distribution and effectively avoiding losses for businesses. The moving mechanism clamps the beef conveyed from the conveyor belt and delivers it into the vacuum chamber, where the packaging mechanism performs vacuum packaging. This eliminates the need for manual handling, effectively reducing labor costs and improving packaging efficiency.

[0004] The patent description mentions that "beef is transferred to the electric tilting hopper via a feeding hopper, and the weight of the beef in the hopper is sensed by a pressure sensor." In the material feeding stage, most packaging machines rely on manual operation, which is not only labor-intensive but also makes it difficult to precisely control the force and position when manually handling the beef. For beef with irregular shapes and varying sizes, unstable handling and placement deviations can easily occur, affecting packaging effectiveness and product quality. Furthermore, the limited speed of manual operation further restricts the improvement of overall packaging efficiency. To address these issues, a dual-station, high-efficiency, multi-functional beef vacuum packaging machine is proposed. Utility Model Content

[0005] The present invention proposes a dual-station high-efficiency multi-functional beef vacuum packaging machine, which aims to improve the problem that some existing beef vacuum packaging machines cannot quantitatively feed and clamp the packaging bags.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A dual-station high-efficiency multi-functional beef vacuum packaging machine includes a worktable. Multiple extension frames are fixedly connected to the left and right sides of the worktable. Mounting plates are fixedly connected to the top of the extension frames. A quantitative feeding mechanism is fixedly connected to the outer side of two mounting plates that are close to each other. Clamping mechanisms are fixedly connected to the top left and right sides of the worktable. Buffer protection mechanisms are rotatably connected to the inner left and right sides of the worktable.

[0008] The clamping mechanism includes an installation platform, which is fixedly connected to the front and rear ends of the workbench. A sliding plate is slidably connected to the outside of the installation platform. A sliding rod is fixedly connected to the bottom of the sliding plate. A reset assembly is sleeved on the outside of the sliding rod. A clamping plate is fixedly connected to the bottom of the sliding rod. A pull plate is slidably connected to the outside of the installation platform.

[0009] With the above solution: the extension racks on the left and right sides of the workbench firmly support the mounting plate, the quantitative feeding mechanism on it can accurately dispense beef, the clamping mechanism on the top of the workbench is the key function, the sliding plate on the mounting platform can drive the sliding rod and clamping plate to move, the reset component ensures automatic reset after operation, and the pull plate facilitates manual adjustment, thus improving the overall efficiency and stability of packaging.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes a reset spring, which is sleeved outside the sliding rod.

[0012] Through the above solution, the reset component plays a key role. The reset spring is tightly fitted outside the sliding rod, with one end firmly fixed to the bottom of the sliding plate and the other end steadily resting on the mounting platform. When the pull plate is pulled, the sliding plate moves the sliding rod downward, and the clamping plate clamps the packaging material. At this time, the reset spring is compressed and contracts. When the pull plate is released, the reset spring rebounds instantly, pushing the sliding rod and clamping plate to quickly return to their positions, preparing for the next packaging operation and ensuring an efficient and smooth packaging process.

[0013] As a further description of the above technical solution:

[0014] The quantitative feeding mechanism includes multiple connecting plates. The outer side of the connecting plate is fixedly connected to the outside of the mounting plate. A fixing ring is fixedly connected to the outer side of the connecting plate. A feeding tank is fixedly connected inside the fixing ring. A connecting shaft is fixedly connected to the bottom of the feeding tank. A rotating baffle is rotatably connected to the outside of the connecting shaft.

[0015] The above solution utilizes a cleverly designed quantitative feeding mechanism to achieve precise beef dispensing. Multiple connecting plates on the mounting plate firmly support the fixing ring, ensuring the stability of the feeding tank. The feeding tank, serving as a container for storing beef, has a bottom connecting shaft that allows the rotating baffle to rotate flexibly. By controlling the opening and closing angle and time of the rotating baffle, the amount of beef dispensed can be precisely controlled, ensuring a uniform amount of beef in each package, improving packaging efficiency and product quality, and making the packaging process more efficient and orderly.

[0016] As a further description of the above technical solution:

[0017] Weighing columns are fixedly connected to the left and right sides of the extension frame, and a weighing plate is fixedly connected to the top of the weighing column.

[0018] Through the above solution, the weighing columns and weighing plates on the left and right sides of the extension frame play a crucial role. The weighing columns are securely connected to the extension frame, providing solid support for the weighing plates. When the beef falls into the packaging container located on the weighing plate through the quantitative feeding mechanism, the weighing plate can accurately measure the weight of the beef. This design can monitor in real time whether the feeding amount meets the set standard. If there is a deviation, the rotating baffle can be adjusted in time to ensure that the amount of beef in each package is accurate, further improving the reliability of the packaging machine and the stability of product quality.

[0019] As a further description of the above technical solution:

[0020] The buffer protection mechanism includes a fixed shaft, which is rotatably connected to the front and rear sides of the inside of the workbench. A rubber baffle is fixedly connected to the outside of the fixed shaft. A connecting frame is fixedly connected to the bottom of the rubber baffle. A telescopic rod is rotatably connected to the outside of the connecting frame. A connecting frame is rotatably connected to the other end of the telescopic rod. A tension spring is sleeved on the outside of the telescopic rod.

[0021] The above solution allows the fixed shaft to rotate flexibly on both the front and rear sides inside the worktable. The rubber baffle on it can initially buffer vibrations. The bottom connecting frame of the rubber baffle is rotatably connected to the telescopic rod. The connecting frame at the other end of the telescopic rod enhances the linkage. The tension spring on the outside can further absorb energy during extension and retraction, reduce equipment wear, and ensure the stable operation of the packaging machine.

[0022] As a further description of the above technical solution:

[0023] The front and rear sides of the connecting frame are fixedly connected to the inside of the workbench, and the outside of the rubber baffle is rotatably connected to the inside of the workbench.

[0024] With the above solution: the connecting frame is firmly fixed inside the workbench on both the front and rear sides, providing solid support for the entire buffer structure. The rubber baffle is flexibly rotated and connected inside the workbench. When the equipment vibrates during operation, it can respond in time and work with the various components of the buffer mechanism to effectively absorb and disperse the impact force, ensuring the stable operation of the equipment.

[0025] As a further description of the above technical solution:

[0026] The workbench is fixedly connected to both the front and rear sides. A rotating plate is rotatably connected to the outside of the fixed rod. A connecting shaft is rotatably connected to the other end of the rotating plate. A vacuum hot press is fixedly connected to the outer side of the two connecting shafts that are close to each other.

[0027] With the above solution: the rotating plates on the front and rear fixed rods can rotate flexibly, and the other end of the rotating plates is connected to the connecting shaft. The two connecting shafts jointly support the vacuum heat press. During operation, the rotating plates adjust the angle to drive the vacuum heat press into position precisely to complete the packaging process, helping the packaging machine to achieve efficient and precise vacuum heat pressing and sealing of beef.

[0028] As a further description of the above technical solution:

[0029] A switch is fixedly connected to the outer front side of the workbench, and drawers are slidably connected to both the left and right ends of the outer front side of the workbench.

[0030] The above solution results in a user-friendly and practical workbench design for the dual-station beef vacuum packaging machine. The switch is prominently displayed on the front side, allowing operators to easily start and stop the equipment with a single button and control the packaging process. The drawers on the left and right sides of the front can slide smoothly.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the sliding plate can squeeze the return spring through the sliding rod, so that the vacuum bag can be placed inside the installation platform. By releasing the return spring, the return spring rebounds, and then the clamping plate can fix the vacuum bag. At this time, by pulling the vacuum hot press to contact the outside of the pulling plate, the vacuum hot press is driven by pressing the switch to vacuum seal the beef.

[0033] 2. In this utility model, the vacuum-sealed beef is squeezed by the rubber baffle onto the telescopic rod, which causes the tension spring outside the telescopic rod to deform. The rubber baffle then relieves the force, thus buffering and protecting the beef and preventing leakage from the beef packaging. After the beef falls in, the tension spring rebounds, which in turn resets the rubber baffle. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0042] Reference Figures 1 to 3This utility model provides an embodiment of a dual-station high-efficiency multi-functional beef vacuum packaging machine, including a workbench 1. The surface of the workbench 1 is precision-machined to achieve extremely high flatness, ensuring the stability of the packaging operation. Inside the workbench 1, space and corresponding mounting holes are reserved for installing a buffer protection mechanism 12. Multiple extension frames 2 are fixedly connected to the left and right sides of the workbench 1. The multiple extension frames 2 are evenly distributed on both sides of the workbench 1 to provide stable support for the mounting plates 3. The top of the extension frames 2 is fixedly connected to the mounting plates 3. A quantitative feeding mechanism 4 is fixedly connected to the outer side of two mounting plates 3 that are close to each other. The quantitative feeding mechanism 4 includes... Multiple connecting plates 401 are evenly distributed on the outer side of the mounting plate 3, providing an installation base for the fixing ring 402 and the feeding tank 403. The outer side of the connecting plate 401 is fixedly connected to the outer side of the mounting plate 3. The fixing ring 402 is fixedly connected to the outer side of the connecting plate 401. The feeding tank 403 is fixedly connected to the inside of the fixing ring 402. The top of the feeding tank 403 is provided with a feeding port for adding beef, and the bottom is provided with a discharge port connected to the connecting shaft 404. The bottom of the feeding tank 403 is fixedly connected to the connecting shaft 404. The rotating baffle 405 can rotate around the connecting shaft 404 by the gravity of the falling beef.

[0043] This controls the opening and closing of the discharge port of the feeding tank 403, achieving the function of quantitative feeding. A rotating baffle 405 is rotatably connected to the outside of the connecting shaft 404. Clamping mechanisms 5 are fixedly connected to the top left and right sides of the workbench 1. Buffer protection mechanisms 12 are rotatably connected to the inside left and right sides of the workbench 1. The buffer protection mechanism 12 includes a fixed shaft 1201, which is rotatably connected to the front and rear sides of the inside of the workbench 1. A rubber baffle 1202 is fixedly connected to the outside of the fixed shaft 1201. The function of the rubber baffle 1202 is to buffer and protect the beef that collides with the edge of the workbench 1 during the packaging process. To prevent damage to items, a connecting frame 1203 is fixedly connected to the bottom of the rubber baffle 1202. A telescopic rod 1205 is rotatably connected to the outside of the connecting frame 1203. A connecting frame 1204 is rotatably connected to the other end of the telescopic rod 1205, which is used to connect the telescopic rod 1205 to the fixed point inside the workbench 1. A tension spring 1206 is sleeved on the outside of the telescopic rod 1205. When the telescopic rod 1205 retracts, the tension spring 1206 is compressed and stores elastic potential energy. When the external force disappears, the tension spring 1206 releases the elastic potential energy, pushes the telescopic rod 1205 to extend, and resets the rubber baffle 1202, so as to continue to play a buffering and protective role.

[0044] Specifically, the precision-machined workbench 1 provides a stable operating surface with reserved installation positions inside. Multiple evenly distributed extension frames 2 are fixed on both sides to support the mounting plates 3. A quantitative feeding mechanism 4 is provided between the mounting plates 3. The fixing ring 402 is connected to the feeding tank 403 through the connecting plate 401. Beef enters from the top feeding port, and the bottom discharge port is controlled to open and close by the connecting shaft 404 and the rotating baffle 405. Quantitative feeding is achieved by the gravity of the beef. The clamping mechanisms 5 on both sides of the top of the workbench 1 are responsible for fixing the items, while the buffer protection mechanisms 12 on both sides inside ensure packaging safety. When the beef collides with the edge of the workbench 1, the rubber baffle 1202 is impacted and drives the connecting frame 1203, causing the telescopic rod 1205 to compress the tension spring 1206 to store energy. After the external force disappears, the spring releases energy, pushing the telescopic rod 1205 to extend, and the rubber baffle 1202 returns to its original position, continuing to play a buffering role.

[0045] Reference Figures 2 to 4 The clamping mechanism 5 includes a mounting platform 501. The surface of the mounting platform 501 is also provided with a precise groove or guide rail for sliding cooperation with the sliding plate 502 and the pull plate 506. The mounting platform 501 is externally fixedly connected to the front and rear ends of the worktable 1. The mounting platform 501 is externally slidably connected to the sliding plate 502. The bottom of the sliding plate 502 is tightly fitted with the groove or guide rail of the mounting platform 501. Through high-precision processing, it is ensured that the sliding plate 502 can slide smoothly on the mounting platform 501. The bottom of the sliding plate 502 is fixedly connected to the sliding rod 503. The surface of the sliding rod 503 is polished to reduce the friction between it and the return spring 504 and ensure its smoothness during movement. The sliding rod 503 is externally fitted with a return assembly, which includes a return spring 504. When the clamping plate 505 is subjected to external force and moves upward;

[0046] The return spring 504 is compressed and stores elastic potential energy. When the external force disappears, the return spring 504 releases the elastic potential energy and pushes the clamping plate 505 downward to reset. The return spring 504 is sleeved on the outside of the sliding rod 503. The bottom of the sliding rod 503 is fixedly connected to the clamping plate 505, which is firmly fixed to the bottom of the sliding rod 503 to ensure that the clamping plate 505 and the sliding rod 503 remain synchronized during the movement. The surface of the clamping plate 505 is specially treated to increase friction and improve the stability of clamping. The mounting platform 501 is slidably connected to the outside of the pull plate 506. The pull plate 506 drives the sliding plate 502 to slide on the mounting platform 501, and then drives the clamping plate 505 to move up or down through the sliding rod 503 to realize the clamping and releasing operation of the item.

[0047] Specifically, the mounting platform 501 is fixed at both ends of the workbench 1, and its surface has precise grooves or guide rails for sliding cooperation with the sliding plate 502 and the pull plate 506. The bottom of the sliding plate 502 fits tightly with the groove, allowing for smooth sliding. A polished sliding rod 503 is connected below it, and a return spring 504 is sleeved on the sliding rod 503. The clamping plate 505 is fixed to the bottom of the sliding rod 503, and its surface is specially treated to increase friction. When the pull plate 506 slides on the mounting platform 501, it drives the sliding plate 502 to move, which in turn causes the clamping plate 505 to move up and down through the sliding rod 503. When the external force causes the clamping plate 505 to move upward, the return spring 504 is compressed and stores energy. When the external force disappears, the spring releases its elastic potential energy, pushing the clamping plate 505 to return to its original position, thus achieving stable clamping and releasing of items.

[0048] Reference Figures 3 to 5 Weighing columns 406 are fixedly connected to the left and right sides of the extension frame 2. When beef is placed on it, the sensor inside the weighing column 406 senses the pressure change and converts it into weight data, allowing operators to understand the weight of the beef for quantitative packaging. A weighing plate 407 is fixedly connected to the top of the weighing column 406. The front and rear sides of the connecting frame 1204 are fixedly connected to the inside of the workbench 1. The rubber baffle 1202 is rotatably connected to the inside of the workbench 1, allowing it to rotate around the connection point when subjected to external impact, thus providing cushioning and protection, reducing the impact force on the equipment during operation, and extending the service life of the equipment. The workbench 1 has fixed rods 7 on both the front and rear sides. Rotating plates 8 are rotatably connected to the outside of the fixed rods 7, allowing the rotating plates 8 to rotate freely around the fixed rods 7, providing flexibility for the movement of the vacuum heat press 10. A connecting shaft 9 is rotatably connected to the other end of the rotating plate 8, allowing the vacuum heat press 10 to move to a suitable position as the rotating plate 8 rotates, performing vacuum compression packaging on the beef packaging bags placed on the workbench 1. The vacuum heat press 10 is fixedly connected to the adjacent sides of the two connecting shafts 9. A switch 11 is fixedly connected to the front of the workbench 1. The switch 11 is typically an electrical control switch with good insulation and a pleasant operating feel. It can control the power supply of the entire packaging machine and the start and stop of various functional modules, facilitating operation and control of the equipment by the operator. Drawers 6 are slidably connected to the left and right ends of the front of the workbench 1.

[0049] Specifically, the extension frame 2 has weighing columns 406 fixed on both sides and a weighing plate 407 connected to the top for placing beef. Sensors inside the weighing columns 406 convert pressure changes into weight data, aiding in quantitative packaging. The workbench 1 has a connecting frame 1204 internally connected, with rubber baffles 1202 rotatably connected to its front and rear sides for cushioning and protection. Fixed rods 7 on both sides of the workbench 1 are rotatably connected to a rotating plate 8. The rotating plate 8 is connected to a vacuum heat press 10 via a connecting shaft 9, facilitating the movement of the equipment to a suitable position for vacuum heat pressing of the beef bags. A switch 11 is located on the front of the workbench 1 to control the power supply and start / stop of various functional modules. Additionally, sliding drawers 6 are located on the left and right sides of the front of the workbench 1.

[0050] Working principle: By placing beef inside the feeding tank 403, the weight of the beef drives the rotating baffle 405 to rotate. Under the action of the rotating baffle 405, the beef falls to the outside of the weighing plate 407 for weighing. At this time, the beef is bagged and placed inside the pull plate 506. By pulling the sliding plate 502, the sliding plate 502 can squeeze the return spring 504 through the sliding rod 503, so that the vacuum bag can be placed inside the mounting platform 501. By releasing the return spring 504, the return spring 504 rebounds, which allows the clamping plate 505 to fix the vacuum bag. At this time, by pulling the vacuum heat press 10 to contact the outside of the pull plate 506, the vacuum heat press 10 is driven by pressing the switch 11 to vacuum seal the beef.

[0051] At this moment, by pulling drawer 6, the vacuum-sealed beef is squeezed by the rubber baffle 1202 onto the telescopic rod 1205, which in turn causes the tension spring 1206 outside the telescopic rod 1205 to deform. The rubber baffle 1202 then relieves the force, thus cushioning and protecting the beef and preventing leakage from the beef packaging. After the beef falls in, the tension spring 1206 rebounds, which in turn resets the rubber baffle 1202.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
