Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and more specifically, to a vacuum packaging device. Background Technology

[0002] Vacuum packaging technology, as a key means of food preservation and moisture and rust prevention, has been widely used in food processing, pharmaceutical storage, and electronic component transportation. Its core principle is to create a negative pressure environment by removing air from the packaging container, inhibiting microbial growth and slowing down oxidation reactions, thereby extending the shelf life or improving storage stability. Therefore, vacuum packaging devices have become important equipment in related industries and for daily household use. Existing technologies, such as the fully automatic pre-prepared ready-to-eat meal packaging system disclosed in CN209142491U, include a hopper, a transverse conveyor belt located on one side of the hopper, a vertical conveying mechanism installed on one side of the transverse conveyor belt, a mixing device located below the upper end of the vertical conveying mechanism, a bagging mechanism located below the mixing device, a vacuum packaging device located on one side of the bagging mechanism, a transfer gripper connected between the bagging mechanism and the vacuum packaging device via a rotating bracket, and conveying grippers on both sides of the vacuum packaging device via a sliding rail bracket. However, while the above-mentioned technical solutions can achieve fully automated mechanized production of pre-made ready-to-eat meals, including raw material transportation, mixing and seasoning, bagging and vacuum sealing, the packaging bags cannot be kept vertical during the packaging process, which affects packaging efficiency. In addition, users need to manually place the packaging bags and align them with the air extraction port, which involves many steps and requires continuous user participation throughout the process, resulting in a poor user experience.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0025] like Figures 1-3As shown, a vacuum packaging device according to one embodiment of the present invention includes a turntable mechanism 1 and a spreading mechanism 2, a filling mechanism 3 and a heat sealing mechanism 4 arranged sequentially along the circumferential direction of the turntable mechanism 1. A plurality of clamps 11 for holding the packaging bag 10 are spaced apart on the outer periphery of the turntable mechanism 1. A suction cup assembly is movably provided on the spreading mechanism 2. The suction cup assembly includes two spreading suction cups 21 arranged in opposite directions. A heat sealing assembly is movably provided on the heat sealing mechanism 4. The heat sealing assembly includes a vacuuming structure 41 and two heat sealing blades 42 arranged in opposite directions. The vacuuming structure 41 is located between the two heat sealing blades 42 and can be raised and lowered relative to the turntable mechanism 1. A plurality of air extraction pipes 411 extending into the inside of the packaging bag 10 are provided on the vacuuming structure 41.

[0026] The aforementioned vacuum packaging device, through the coordinated operation of the turntable mechanism 1 and the various functional mechanisms arranged around the perimeter, realizes the automated assembly line operation of the packaging bag 10's opening, filling, vacuuming, and heat sealing processes. The clamps 11 hold the packaging bag 10 and pass it through each station in sequence, ensuring that the packaging bag 10 remains in a vertical position without manual intervention, which greatly improves production efficiency and is particularly suitable for continuous packaging needs. Vacuuming and heat sealing are closely connected and continuously completed at the same station, avoiding the loss of vacuum degree inside the bag during the transfer process, which greatly improves the reliability of sealing and the packaging yield.

[0027] like Figure 1 As shown, in one embodiment, the vacuum packaging device further includes a processing table 5, covered by a protective shell 6. A processing space is formed between the protective shell 6 and the processing table 5. The turntable mechanism 1, the opening mechanism 2, the filling mechanism 3, and the heat sealing mechanism 4 are all installed within the processing space. A filling funnel 61 is provided on the top of the protective shell 6. The enclosed processing space can effectively isolate the external environment, not only reducing the contamination of packaged items (especially food) by dust, insects, and other pollutants, ensuring hygiene standards, but also preventing the splashing of powder, liquid, or oil stains that may be generated during the packaging process, keeping the working area clean.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, a turntable component is rotatably mounted on the turntable mechanism 1. A mounting ring is fitted around the outer periphery of the turntable component. Several first drive cylinders are fixed to the top of the turntable component. Each first drive cylinder has a spreading plate 12 connected to its output end. Multiple clamps 11 are spaced apart on the mounting ring. When a clamp 11 rotates to the spreading position, its corresponding first drive cylinder can be started individually, driving the spreading plate 12 to perform the opening action of the packaging bag 10.

[0029] In one embodiment, the clamp 11 includes a mounting base, a lifting member, and two clamping members that can slide relative to the mounting ring. The mounting base is threadedly fixed to the mounting ring, and the mounting base is provided with a lifting guide rail. The lifting member is slidably assembled on the lifting guide rail, and the two clamping members are symmetrically arranged on both sides of the lifting member.

[0030] Specifically, the lifting guide rail is set in a vertical direction.

[0031] In one embodiment, the clamping component includes a connecting block and a clamping block. One end of the connecting block is connected to a lifting component, and a lower clamp is fixedly mounted on the other end of the connecting block. The clamping block includes a first swing arm, a second swing arm, and an upper clamp. The first swing arm is rotatably mounted on the connecting block, and the second swing arm is rotatably connected between the first swing arm and the upper clamp. The upper clamp is rotatably mounted on the connecting block and cooperates with the lower clamp to clamp the packaging bag 10. The upper clamp is connected to the connecting block through the first and second swing arms, so that the upper clamp does not move in a simple linear motion when pressed down, but has a small adaptive swing range. When the upper and lower clamps begin to close and clamp the packaging bag 10, the upper clamp is allowed to automatically adjust its angle and position to ensure that its upper clamping surface forms a surface contact with the fixed lower clamping surface, rather than a line contact or point contact. This completely avoids problems such as local stress concentration, puncture, or tearing at the bag opening that may be caused by traditional rigid clamping. It is particularly suitable for handling soft, ultra-thin, or easily damaged packaging bags 10, significantly reducing the bag breakage rate and scrap rate.

[0032] like Figure 1 and Figure 4 As shown, in one embodiment, the vacuum packaging apparatus further includes an upper bag mechanism 7 and a lower bag conveyor belt 8 installed within the processing space. The upper bag mechanism 7 includes an upper bag assembly 71 and a bag-retrieving assembly 72 for transferring the packaging bag 10 from the upper bag assembly 71 to the clamp 11. The upper bag assembly 71 is divided into an upper bag unit and a bag-retrieving unit by a limiting plate 711. The upper bag unit is provided with multiple conveying wheels, and the bag-retrieving unit is provided with multiple limiting wheels 712. The discharge end of the lower bag conveyor belt 8 extends outside the processing space. This facilitates the loading of new packaging bags 10 and the unloading of packaged bags 10 after they have been filled.

[0033] like Figure 4 As shown, in one embodiment, the bag-grabbing assembly 72 includes a fixed base 721, a drive structure 722, and a bag-grabbing gripper 723. The fixed base 721 is mounted on the processing table 5, and the drive structure 722 is mounted on the fixed base 721 and used to control the running trajectory of the bag-grabbing gripper 723. The bag-grabbing gripper 723 is provided with a gripper part 7231 and a second drive cylinder for controlling the gripping state of the gripper part 7231. By adjusting the air pressure or replacing the gripper part 7231, it can flexibly adapt to packaging bags 10 of different materials and sizes, ensuring reliable gripping without damaging the packaging bag 10 due to excessive clamping force.

[0034] like Figure 2 As shown, in one embodiment, the suction cup assembly further includes a first adjusting member and a second adjusting member slidably mounted on the spreading mechanism 2, respectively. One spreading suction cup 21 is disposed on the first adjusting member, and the other spreading suction cup 21 is disposed on the second adjusting member. The two spreading suction cups 21 are used to adsorb the two sides of the packaging bag 10, respectively. This allows the distance between the two spreading suction cups 21 to be flexibly and precisely adjusted according to the width of the packaging bag 10.

[0035] like Figure 2 As shown, in one embodiment, the loading mechanism 3 includes a support rod, fasteners, and a hopper 31 communicating with the loading funnel 61. The support rod is mounted on the processing table 5. One end of the fastener is inserted into and locked to the top of the support rod, and the other end of the fastener is fixedly connected to the hopper 31. The hopper 31 is fixed to the top of the support rod by the fasteners, which are inserted and locked in place. The structure is simple, rigid, and stable, effectively bearing the weight of the hopper 31 and the material, preventing the hopper 31 from shaking or shifting due to vibration during equipment operation, thus ensuring the stability of the loading process.

[0036] like Figure 2 As shown, in one embodiment, the vacuum packaging device further includes a marking mechanism 9 installed in the processing space. The marking mechanism 9 is located between the filling mechanism 3 and the heat sealing mechanism 4. A marking component is movably mounted on the marking mechanism 9, and the marking component is equipped with a marking head that can reciprocate into the packaging bag 10. Compared with external inkjet printing or labeling, internal marking allows the identification information (such as production date, batch number, shelf life, etc.) to be sealed inside the bag, completely avoiding the problems of blurred, detached, or lost labels caused by friction, moisture, or contact with chemicals during transportation and sales, thus ensuring the integrity and readability of product information.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
