Description

Technical Field

[0001] The invention relates to a vacuum sealing packaging machine, belonging to the field of packaging equipment. Background Art

[0002] Vacuum packaging machines are widely used in the food industry for freshness preservation, primarily for packaging meat, seafood, prepared foods, and nut snacks. Their working principle is: After the food is placed in a specialized bag, the air inside is extracted using negative pressure vacuum technology. Once a sealed vacuum environment is created, the bag is immediately heat-sealed.

[0003] During a critical step in the packaging process, as the vacuum pump continuously extracts gas from the bag, the bag adaptively shrinks due to the pressure difference between the inside and outside. This characteristic is effective for preserving solid-shaped foods (such as meat products), but it presents significant process limitations when packaging products containing rollable nuts (such as walnuts and almonds) or granular snacks. The moment the air is extracted from the bag, the loose food particles will shift irregularly due to the bag's shrinkage, making it difficult to maintain a regular final packaging shape. This deformation not only affects the aesthetics of product display but also creates positioning difficulties in subsequent automated packaging processes (such as boxing and palletizing), reducing overall packaging line efficiency.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0024] In the current packaging process, when vacuum pumps continuously extract air from the bag to roll nuts (such as walnuts and almonds) or granular snacks, there are obvious process limitations. When the air in the bag is extracted, the loose food particles will be irregularly displaced due to the bag's shrinkage, making it difficult to maintain a regular final packaging shape. To address this issue, this case proposes the following technical solutions: See also Figures 1 to 6 The present invention provides a technical solution for a vacuum sealing packaging machine: its structure includes: a machine body 6, a rotating feeding turntable 3 is installed in the middle of the machine body 6, the feeding turntable 3 rotates clockwise and is sequentially provided with a material belt conveyor 1, a feeding hopper 5, a poker 4 and a vacuum part 2, the material belt conveyor 1 is installed on the side of the machine body 6, the feeding hopper 5 cooperates with the movable rod of the poker 4, and the central groove of the feeding hopper 5 is pressed by the poker 4, the feeding turntable 3 rotates to connect the feeding hopper 5 and the vacuum part 2, the vacuum part 2 includes a vacuum machine 21 and a sliding mechanism 22, the vacuum machine 21 is movably connected to the sliding mechanism 22, the divider 23 of the vacuum part 2 is installed in the frame of the machine body 6, opposite to the gripper of the feeding turntable 3, the vacuum machine 21 includes a positioning plate 211 and a vacuum bin 212, and the positioning plate 211 is movably connected to the vacuum bin 212; The positioning plate 211 includes a base plate 111 and a movable plate 112. The push rod inside the base plate 111 drives the movable plate 112 to move horizontally. A sealer 113 is installed on the surface of the movable plate 112. The sealer 113 is respectively arranged on the surface of the movable plate 112 and the inner surface of the vacuum chamber 212. The surface of the movable plate 112 is symmetrically provided with clamping heads 114. The clamping heads 114 are respectively matched with driving rods 115, and a sorting base plate 116 is arranged between the clamping heads 114.

[0025] When in use, the main structure of this device includes a material belt conveyor part 1, which is used to place packaging bags, a feeding turntable 3, which is used to convey packaging bags. The feeding turntable 3 clamps and stretches the empty bag and passes it through the position of the feed hopper 5 for manual discharge, or an external production line is connected for automatic feeding. After feeding, the poketer 4 on the top is used to assist so that the food can be completely poured into the bag.

[0026] The filled packaging bags are transported to the vacuum part 2 for vacuum packaging through the rotation of the feeding turntable 3. The vacuum part 2 includes a vacuum machine 21, a sliding mechanism 22, and a divider 23. The divider 23 receives the packaging materials transported by the feeding turntable 3. After receiving, the vacuum machine 21 moves to the divider 23 to transfer the packaging, and then moves to the side to work. The work efficiency is improved by alternating the left and right vacuum machines 21.

[0027] The vacuum machine 21 consists of a positioning plate 211, a vacuum chamber 212 and a vacuum tube 213. The positioning plate 211 is used to clamp the bag body. The clamped positioning plate 211 is transported to the vacuum chamber 212 through the cooperation of the first driver 223 and the rack 224 of the bottom sliding mechanism 22. The vacuum tube 213 is connected to the pump body inside the machine body 6, so that the inner cavity of the vacuum chamber 212 generates negative pressure to extract the air in the package.

[0028] The above-mentioned vacuum machine 21 moves left and right by fixing the positioning plate 211 through the slide rail 221 on the surface of the supporting cross bar 222. A rack 224 is set at the bottom of the positioning plate 211. The rack 224 is fixed to the bottom of the slide rail 221 by bolts, and the rack 224 is driven to move by the first driver 223 installed inside the body 6. The outer teeth of the first driver 223 push the outer teeth of the rack 224 to move horizontally left and right, and the transmission through the gear rack method can be more stable.

[0029] The structure of the positioning plate 211 includes a bottom plate 111, which is connected to a rack 224 as a base to support the movable plate 112. A sliding movable plate 112 is provided on the surface of the bottom plate 111. The movable plate 112 cooperates with the bottom plate 111 through a sliding rod. A sealer 113 is provided on the inner surface of the movable plate 112. The sealer 113 is used for hot pressing and sealing. The sealer 113 is divided into two parts, which are respectively installed inside the vacuum chamber 212 and on the surface of the movable plate 112. After the vacuum is completed, the push rod at the rear end of the bottom plate 111 will drive the movable plate 112 to move horizontally, and then the sealer 113 is engaged and hot pressed. The surface of the movable plate 112 is also provided with a clamping head 114 that cooperates with the sealer 113. The clamping head 114 is connected to the driving rod 115. The rack of the driving rod 115 drives the clamping head 114 to rotate. When the clamping head 114 rotates to fit the clamping block on the surface of the movable plate 112, it clamps the package. When the driving rod 115 retracts, the clamping head 114 can be released. The rotary clamping type can make the package fall under the action of gravity after sealing, thereby improving the packaging efficiency.

[0030] When packaging some nuts that roll vertically, they tend to accumulate at the bottom, causing bulges during packaging and affecting the subsequent packaging of the outer packaging. Although this problem can be solved by placing the packaging bag horizontally, another feeding mechanism is required to unload the package after packaging. In addition, the horizontal packaging bag method is not effective when handling some packages containing liquids. Therefore, this application further optimizes the vertical packaging method: A finishing base plate 116 is provided on the surface of the specific movable plate 112, and positioning is performed by the finishing base plate 116. A shaping groove 165 is provided on the surface of the plate body 162 of the finishing base plate 116 for positioning. Since the hanging bag mouth will shrink during vacuuming, it is inconvenient for the sliding ring 163 on the surface of the plate body 162 to move and level it. Therefore, this device provides a clamp 161 at the bottom of the plate body 162 for clamping.

[0031] The chuck 161 cooperates with the synchronization rod 662 of the driving device 166 installed on the rear surface of the plate body 162. The synchronization rods 662 are linked by a synchronization belt 663 and driven by a second driver 664. The surface of the synchronization belt 663 is also connected to the sliding ring 163. When the synchronization belt 663 moves, the sliding ring 163 is driven to move up and down. The sliding ring 163 is also nested with the slide groove 661 of the column 665, which can be smoother when moving. When moving, the pressure plate 164 on the surface of the sliding ring 163 flattens the package clamped between the chuck 161 and the clamping head 114. When the pressure plate 164 sweeps over, the raised rolling food enters the interior of the plate body 162 for nesting. At this time, synchronous vacuuming is performed to avoid secondary displacement of the food.

[0032] In order to make the structure more compact, the clamping head 161 is further optimized. Side arms 613 are set on both sides of the clamping teeth 611 of the clamping head 161, which are connected to the synchronization rod 662 through the limiting side plates 614 on the surface of the side arms 613, and the first gear 615 is connected to the second gear 616. The first gear 615 and the second gear 616 are limited by the limiting side plates 614. The limiting side plates 614 and the side arms 613 are movably matched. When rotating, they drive the second gear 616 to generate resistance, thereby driving the clamping teeth 611 to clamp upward. When the synchronization rod 662 rotates in the opposite direction, the clamping teeth 611 move downward. In order to increase the clamping force, a pressure bar 612 is nested on the surface of the clamping teeth 611. The pressure bar 612 uses a rubber strip, which fits the packaging surface to prevent it from falling off.

[0033] A pressure head 617 is also provided in the middle of the second gear 616. A spring is installed inside the pressure head 617. When the spring is pressed tightly, the resistance to the rotation of the second gear 616 is increased, and the clamping torque can also be increased.

[0034] The improved device cooperates with the double-station vacuum chamber 212 and the positioning plate 211 to improve the vacuum efficiency, flattens the packaged food by adjusting the bottom plate 116 on the surface of the movable plate 112, and shapes it through the shaping groove 165 on the surface of the plate body 162. The sliding ring 163 assists in leveling the driving pressure plate 164 of the synchronization rod 662 and the synchronization belt 663, which facilitates the processing of the package. The synchronization rod 662 drives the clamp 161 to rotate, and the resistance generated by the first gear 615 and the second gear 616 rotates the clamping teeth 611, which can achieve compact transmission and enable the clamping teeth 611 to clamp the package, reducing the deformation of the package during vacuuming and making it flatter.

[0035] The above only describes the basic principles and preferred embodiments of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the scope of protection of the present invention.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
