Description

Technical Field

[0001] This utility model relates to the field of luncheon meat production, specifically a luncheon meat vacuum packaging machine. Background Technology

[0002] Luncheon meat is a packaged, ready-to-eat meat product made primarily from pork, along with starch, salt, sugar, and spices. Thanks to its long shelf life, portability, and ease of consumption, it has gradually transitioned from military rations to the civilian market, becoming a classic ingredient for family emergency reserves, outdoor camping, and fast food preparation.

[0003] A luncheon meat vacuum packaging machine is a packaging device specifically designed for luncheon meat and other meat products. Its core function is to extract air from the packaging and seal it, thereby extending the shelf life of the luncheon meat and maintaining its flavor and quality. Compared to traditional filling processes, vacuum packaging machines are well-suited for the production needs of bagged luncheon meat. They effectively isolate oxygen and microorganisms, inhibiting oxidation and spoilage of the food and bacterial growth, while also reducing packaging volume and lowering storage and transportation costs. However, during the sealing process, a good clamp is often needed to hold and secure the packaging bag. With technological advancements, the clamping mechanism has become a key component for achieving packaging sealing. It is mainly responsible for stably clamping the opening of the luncheon meat packaging bag during the vacuum extraction and sealing stages. It must firmly fix the bag opening position to prevent displacement and leakage due to changes in air pressure inside the bag, ensuring that the vacuum pump can smoothly extract air from the bag. In the sealing process, it works with a heating strip to press the bag opening film, causing the film to fuse and seal at high temperatures, ensuring the airtightness of the packaging.

[0004] However, this clamping mechanism can only clamp the items and lacks other more complex functions. It cannot effectively squeeze and unfold the packaging bag according to actual needs. In subsequent stages requiring meat filling and vacuuming, the packaging bag's incomplete opening hinders the efficient completion of these critical steps. This not only significantly reduces the overall operating efficiency of the production line but may also negatively impact the quality of the final product, preventing it from meeting expected standards and thus affecting market competitiveness and consumer satisfaction. Utility Model Content

[0005] This invention provides a luncheon meat vacuum packaging machine that solves the problem that the clamping mechanism can only clamp and cannot squeeze open the packaging bag as needed, which is not conducive to subsequent meat filling and vacuuming, resulting in reduced production efficiency and poor product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A luncheon meat vacuum packaging machine includes a base and a fixed disc. Multiple connecting rods are fixedly connected to the outer wall of the fixed disc. A driving component is fixed to the top of each connecting rod. A bevel gear is connected to the output end of the driving component, and the bevel gear meshes with a bevel tooth. A bidirectional threaded rod is connected to the center of the bevel tooth. The bidirectional threaded rod has two threads in opposite directions at both ends. Two identical L-shaped fixing plates are threadedly connected to the outer wall of the bidirectional threaded rod. A sliding plate is provided on the inner side of the L-shaped fixing plate, and the sliding plate is slidably connected to the outer side of the connecting rod. A clamping assembly is provided at the front end of the L-shaped fixing plate. A driving assembly is provided at the top of the base, and a lifting mechanism for raising and lowering the fixed disc is provided at the bottom of the fixed disc.

[0007] As a preferred embodiment of this utility model, the lifting mechanism includes a toothed hole, which is located in the middle of the fixed disc. A toothed guide rail is engaged with the inner wall of the toothed hole. A support rod is fixedly connected to the bottom of the toothed guide rail. The bottom of the support rod is rotatably connected to the top of the base. A fixed ring is fixed to the top of the outer wall of the support rod. Two electric actuators are fixed to the top of each fixed ring. The output ends of the two electric actuators are fixedly connected to the bottom of the fixed disc.

[0008] As a preferred technical solution of this utility model, the clamping assembly includes an electric push rod II, a clamp and a magnetic column. The electric push rod II is located on the top of the L-shaped fixing plate, the clamp is fixed at the output end of the electric push rod II, and the magnetic column is located at the center of the clamp and the L-shaped fixing plate, for clamping the packaging bag.

[0009] As a preferred technical solution of this utility model, the driving assembly includes a second driving component, a rotating disk, a fixed column, and a five-point gear. The second driving component is located on the top of the base, and the output end of the second driving component is fixedly connected to the bottom of the rotating disk. The top of the rotating disk is connected to the fixed column, and the fixed column is engaged with the five-point gear.

[0010] As a preferred embodiment of this utility model, a support frame is fixed to the top of the base, and a vacuum machine is fixed to the top of the support frame.

[0011] In a preferred embodiment of this invention, a vacuum nozzle and a meat-filling tube are fixed to the bottom of the support frame, and the top of the vacuum nozzle is connected to a vacuum machine for vacuuming. The present invention has the following advantages: 1. By activating the second electric actuator, the clamp and magnetic column will move until they engage with the L-shaped fixing plate to lock the packaging. Then, the first drive unit will be activated, which will drive the first bevel gear to rotate. The first bevel gear will then drive the second bevel gear to rotate, which will then drive the bidirectional threaded rod to rotate. The bidirectional threaded rod will then push the L-shaped fixing plates on both sides inward, while the sliding plate will move inward toward the connecting rod, creating a gap in the packaging bag. This allows the packaging bag to be opened by contracting inward, facilitating subsequent meat filling and vacuuming.

[0012] 2. By activating the electric actuator on the fixed ring, the electric actuator will push the fixed disc upward. At the same time, a toothed hole is opened at the center of the fixed disc. The teeth of the toothed hole match the teeth of the toothed guide rail, allowing the fixed disc to move up and down on the outer wall of the toothed guide rail and rotate with the toothed guide rail. This enables the fixed disc to be pushed onto the vacuum nozzle and meat filling tube during filling and vacuuming, preventing deviation. Attached Figure Description

[0019] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Please see Figure 1 , Figure 2 and Figure 4 A luncheon meat vacuum packaging machine is disclosed. The device mainly consists of a base 1 and a fixed disc 3. Multiple connecting rods 4 are evenly fixed to the outer wall of the fixed disc 3. A driving component 5 is fixed to the top of each connecting rod 4, and the output end of the driving component 5 is connected to a bevel gear 6. The bevel gear 6 meshes with another bevel gear 7, enabling it to change the direction of rotation. A bidirectional threaded rod 8 is connected to the center of the bevel gear 7. The two ends of this bidirectional threaded rod 8 have threads in opposite directions, and two identical L-shaped fixing plates 10 are connected to the outer wall of the bidirectional threaded rod 8 by threaded connection. A sliding plate 9 is provided on the inner side of the L-shaped fixing plate 10, which can slide against the outer side of the connecting rods 4. A clamping assembly is also provided at the front end of the L-shaped fixing plate 10. In addition, a driving assembly is provided on the top of the base 1, and a lifting mechanism 2 is provided at the bottom of the fixed disc 3. The main function of this lifting mechanism 2 is to lift the fixed disc 3.

[0021] In one instance of this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The lifting mechanism 2 includes a toothed hole 201, which is located in the center of the fixed disc 3. The inner wall of the toothed hole 201 engages with the toothed guide rail 202, ensuring a stable connection and precise transmission. The bottom of the toothed guide rail 202 is firmly connected to the support rod 203, and the bottom of the support rod 203 is rotatably connected to the top of the base 1, thus supporting the toothed guide rail 202. Additionally, a fixing ring 204 is fixedly installed on the top of the outer wall of the support rod 203. Two electric actuators 205 are evenly fixed to the top of the fixing ring 204. The output ends of these two electric actuators 205 are tightly connected to the bottom of the fixed disc 3, thereby driving the fixed disc 3 to perform corresponding lifting and lowering movements through the operation of the electric actuators 205.

[0022] In one instance of this embodiment, please refer to Figure 1 and Figure 4The clamping assembly mainly consists of an electric actuator 11, a clamp 12, and a magnetic column 13. The electric actuator 11 is positioned at the top of the L-shaped fixing plate 10, while the clamp 12 is securely mounted on the output end of the electric actuator 11. The magnetic column 13 is located at the center of the clamp 12 and the L-shaped fixing plate 10, and its main function is to securely clamp the packaging bag. The driving assembly includes a driving component 14, a rotating disk 15, a fixed column 16, and a five-element gear 17. The driving component 14 is positioned at the top of the base 1, and its output end is fixedly connected to the bottom of the rotating disk 15. The top of the rotating disk 15 is connected to the fixed column 16, and the fixed column 16 and the five-element gear 17 are engaged with each other, thereby realizing the functional linkage of the entire driving assembly.

[0023] In one instance of this embodiment, please refer to Figure 1 and Figure 2 A support frame 18 is securely fixed to the top of the base 1, and a vacuum machine 19 is fixedly mounted on the top of this support frame 18. A vacuum nozzle 20 and a meat-filling tube 21 are fixedly installed at the bottom of the support frame 18. The top of the vacuum nozzle 20 is connected to the vacuum machine 19 to perform a vacuuming operation. This allows the entire device to effectively complete the vacuuming task during operation, thus ensuring the smooth progress of related procedures.

[0024] In the implementation of this utility model, the second driving component 14 is activated. At this time, the second driving component 14 will drive the rotating disk 15 to rotate. At this time, the fixed column 16 at the top of the rotating disk 15 will move eccentrically around the rotating disk 15. At the same time, when the fixed column 16 moves to the groove of the five-part gear 17, it will drive the five-part gear 17 to rotate until the fixed column 16 leaves the five-part gear 17. At this time, the five-part gear 17 will not continue to move. At this time, the luncheon meat packaging box can be filled with meat and vacuumed through the meat filling tube 21 and the vacuum nozzle 20.

[0025] First, activate electric actuator 11. Electric actuator 11 will then move clamp 12 and magnetic column 13 away from L-shaped fixing plate 10, creating a gap between them. Place the package between L-shaped fixing plate 10 and clamp 12, and activate electric actuator 11 again. Electric actuator 11 will then move clamp 12 and magnetic column 13 until they engage with L-shaped fixing plate 10 and hold the package in place. Next, activate drive component 5. Drive component 5 will then rotate bevel gear 6, which in turn will rotate bevel gear 7. Bevel gear 7 will then rotate bidirectional threaded rod 8, which will push the L-shaped fixing plates 10 on both sides inward. Simultaneously, sliding plate 9 will move inward towards connecting rod 4, creating a gap in the packaging bag. This allows the packaging bag to open by contracting inward, facilitating subsequent meat filling and vacuuming.

[0026] When meat filling and vacuuming are required, the electric actuator 205 on the fixed ring 204 is activated. At this time, the electric actuator 205 will push the fixed disc 3 upward. At the same time, the fixed disc 3 has a toothed hole 201 at its center. The toothed pattern of the toothed hole 201 matches the toothed pattern of the toothed guide rail 202, so that the fixed disc 3 can move up and down on the outer wall of the toothed guide rail 202 and can rotate with the toothed guide rail 202. This allows the fixed disc 3 to be pushed onto the vacuum nozzle 20 and the meat filling tube 21 during filling and vacuuming, preventing deviation.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
