Description

Technical Field

[0001] This invention relates to the field of seafood noodle and rice processing technology, specifically to a vacuum packaging device for seafood noodle and rice products. Background Technology

[0002] Seafood noodle and rice products are a type of food made from grains such as flour and rice, combined with seafood ingredients such as shrimp, crab, shellfish, fish paste, and squid. They are produced through processes such as kneading, shaping, steaming, and quick-freezing. They cover multiple categories and combine the satiety of grains with the fresh flavor of seafood. They are one of the mainstream foods that meet the needs of convenient diets. The vacuum packaging of seafood products in seafood noodle and rice products is mainly completed by food vacuum packaging machines. The workflow is usually that the processed seafood is first placed into a suitable vacuum bag by hand. Then, the vacuum bag is placed in the vacuum chamber of the vacuum packaging machine. After the equipment is started, the vacuum pump begins to extract the air from the bag, creating a low-oxygen or anaerobic environment inside the bag. During this process, the control system monitors the vacuum level in real time. When the set value is reached, the vacuum pump stops working. Subsequently, the heat sealing mechanism is activated under vacuum conditions. The high temperature melts the opening of the packaging bag, completing the sealing process. This isolates the outside air and achieves the purposes of preservation, moisture prevention, and mold prevention.

[0003] In the existing technical field, traditional seafood packaging relies on manual labor to fill materials into vacuum bags and move them around. This method is difficult to match with large-scale production, and manual contact with materials can easily cause microbial contamination, which does not meet food hygiene standards. In addition, seafood products are prone to residual moisture or seepage of broth after processing. The existing traditional vacuum packaging process does not have a dedicated liquid pretreatment function. When vacuuming materials containing liquid directly, the liquid can easily be sucked into the vacuum pump, causing equipment failure, or the liquid may remain at the bag opening, resulting in incomplete sealing and a small amount of air remaining inside the bag. This reduces the product's shelf life and makes it easy for bacteria to grow. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are: the vacuum packaging device for seafood noodle and rice products:

[0019] 1. The upper third electric telescopic rod extends, driving the corresponding electric suction cup module to move downward and contact the upper part of the vacuum packaging bag on the surface of the second conveyor belt for adsorption. The second electric telescopic rod extends, driving the first rotating seat to rotate downward, thereby causing the first rotating seat to drive the second mounting plate to rotate from vertical to horizontal. The lower third electric telescopic rod extends, driving the corresponding electric suction cup module to move upward and contact the lower part of the vacuum packaging bag on the surface of the second conveyor belt for adsorption. The first electric telescopic rod shortens, driving the rotating frame to rotate upward from vertical to horizontal with the axis at the connection position with the fixed frame as the axis. The front and rear third electric telescopic rods shorten and, with the cooperation of the corresponding electric suction cup modules, open the opening of the vacuum packaging bag.

[0020] 2. The seafood material inside is quantitatively discharged from the hopper into the vacuum packaging bag by the feeder. After the bag is filled, the fourth electric telescopic rod shortens and drives the truss to move the hopper in the material transfer unit out of the vacuum packaging bag. The sixth electric telescopic rod shortens and drives the rotating rod at the corresponding position to rotate upward. Then, under the limiting action of the rotating rod on the other side, the mounting base moves obliquely forward to the opening of the vacuum packaging bag. The first motor drives the second rotating seat to rotate downward inside the fixed seat, so that the second mounting seats on the left and right sides rotate from horizontal to vertical downward.

The left and right micro electric telescopic rods extend and drive the suction needles at the corresponding positions to insert downward into the vacuum packaging bag. With the cooperation of the two suction needles, the vacuum pump extracts the liquid seeping out of the seafood inside the vacuum packaging bag to the outside for centralized collection.

[0021] In summary, this invention, through a highly collaborative automated system, seamlessly connects the feeding, bagging, and packaging processes, reducing manual intervention and avoiding the risk of microbial contamination caused by human contact at the source. This ensures that the product's hygiene and safety meet standards. Furthermore, before vacuum sealing, liquid extraction technology effectively removes free liquid inside the bag, fundamentally solving the problem of seal failure caused by liquid and significantly improving sealing quality and product shelf life.

Two sixth electric telescopic rods 49 are used, with one end rotatably mounted on the center of the left and right sides of the bottom of the second mounting plate 45 via rotating seats. The other ends of the sixth electric telescopic rods 49 are pivotally connected to the outer sides of the two upper rotating rods 48. The sixth electric telescopic rods 49 are electrically connected to the control console 5. A Hall sensor provides position feedback, and the extension / retraction of the drive rod 48 causes the mounting base 410 to rotate, thus adjusting the position of the straw needle 421. The mounting base 410 is rotatably mounted on the inner side of the other end of the left and right sets of drive rods 48 via bearings. The fixed base 411 is fixedly mounted on the top center of the mounting base 410. The vacuum pump 412 is mounted on the top rear side of the fixed base 411 and is electrically connected to the control console 5. The vacuum pump 412 is an oil-free vortex vacuum pump to avoid oil contamination of food and can quickly extract liquid seeping from seafood in the packaging bag. An external collection tank can be added as needed. The second rotating seat 413 is rotatably connected to the upper inner side of the fixed base 411 via bearings. The second rotating seat 413 is L-shaped.The first motor 414 is installed on the inner bottom of the fixed base 411. The rotating end of the first motor 414 is connected to the shaft of the second rotating base 413. The first motor 414 is electrically connected to the control console 5. The first motor 414 is a stepper motor, and the rotation angle is controlled by the pulse signal sent by the control console 5 to ensure that the straw needle 421 is accurately aligned with the opening of the packaging bag. The outer shell 415 is installed on the front top of the second rotating base 413. The outer shell 415 is made of 304 stainless steel with a brushed surface, which serves to protect the internal components. Long slots are opened on both sides of the outer shell 415 to facilitate the movement of the second mounting base 417. There are two limiting components 416, which are respectively installed on the outer shell 413. On the upper and lower sides of the inner cavity of housing 415, the limiting component 416 is a linear guide slider structure to ensure that the second mounting base 417 moves in a straight line; there are two second mounting bases 417, which are respectively installed on the outer side of the limiting ends of the upper and lower limiting components 416. The outer side of the second mounting base 417 extends out of the outer surface of housing 415. The second mounting base 417 is made of aluminum alloy and has an overall L-shaped structure for mounting the miniature electric telescopic rod 420; the second motor 418 is installed on the outer rear end of housing 415. The rotating end of the second motor 418 extends into the inner cavity of housing 415. The second motor 418 is electrically connected to the control console 5. The second motor 418 is a DC servo motor equipped with The reducer lowers the speed and increases the torque. The second motor 418 is equipped with an absolute encoder, enabling closed-loop position control via a control console. The gear of the gear and rack assembly 419 is mounted on the rotating end of the second motor 418. The racks on the upper and lower sides of the gear and rack assembly 419, meshing with the gears, are respectively mounted inside the upper and lower limit assemblies 416.

Two miniature electric telescopic rods 420 are present, mounted along the front-to-back direction on the outer sides of the left and right second mounting bases 417. The device is electrically connected to console 5. The miniature electric telescopic rod 420 has a pen-like structure and its extension and retraction are controlled by console 5, enabling the insertion and withdrawal of the straw needle 421. There are two straw needles 421, installed on the front of the telescopic ends of the left and right miniature electric telescopic rods 420 respectively in the front-back direction. Each straw needle 421 is connected to the vacuum pump 412 via tubing. The straw needle 421 is made of 304 stainless steel with a beveled tip for easy insertion into the packaging bag and to avoid scratching the bag. The surface is polished to reduce liquid residue. The straw needle 421 connects to a silicone hose via a quick-connect fitting for easy disassembly and replacement. A built-in one-way valve prevents liquid backflow.

[0035] The working principle is as follows:

[0036] Step 1: The operator issues a start command via console 5, simultaneously activating material conveyor belt 1, first conveyor belt 23, three-axis gantry robot arm 27, packaging bag feeder 25, packaging bag handling robot arm 26, and second conveyor belt 24. Seafood materials already processed by external equipment are conveyed from the rear of the device to the front via material conveyor belt 1, eventually transferring to the surface of first conveyor belt 23. Inside the outer casing 22, first conveyor belt 23 continues to convey materials forward to the material gripping station below the three-axis gantry robot arm 27. The actuator of the three-axis gantry robot arm 27 grips the seafood materials on the first conveyor belt 23 downwards and then lifts them upwards. The material is moved to the top of the feeding hopper 43 and poured into the feeding hopper 43. The material slides through the feeding hopper 43 into the feeder 42 below and is temporarily stored for later bagging. The packaging bag feeder 25 pushes the blank vacuum packaging bags stacked inside it one by one to its feeding station. The packaging bag handling robot arm 26 drives its execution end to move to the feeding station of the packaging bag feeder 25. The packaging bag handling robot arm 26 drives its execution end to grab a single vacuum packaging bag and move it to the rear surface of the second conveyor belt 24 and put it down. Finally, the second conveyor belt 24 conveys the vacuum packaging bag forward and sends it to the inner station of the gantry frame 31.

[0037] Step 2: The operator activates the third electric telescopic rod 39, the second electric telescopic rod 37, the first electric telescopic rod 34, the fourth electric telescopic rod 313, and the fifth electric telescopic rod 316 via the control console 5. The third electric telescopic rod 39 extends, driving the electric suction cup module 310 at its telescopic end to move downwards until the electric suction cup module 310 makes close contact with the upper surface of the vacuum packaging bag. The electric suction cup module 310 then activates negative pressure suction to hold the upper surface of the packaging bag. The second electric telescopic rod 37 first shortens, driving the first rotating seat 36 connected to it to rotate upwards, thereby causing the second mounting plate 38 to rotate from a horizontal state to a vertical state. This then drives the electric suction cup modules 310 on both sides to separate, putting them in an open state. The second electric telescopic rod 37 extends again, driving the first rotating seat 36 connected to it to rotate downwards, thereby causing the second mounting plate 38 to rotate from a vertical state to a horizontal state, aligning the lower electric suction cup module 310 with the lower edge of the packaging bag. The third electric telescopic rod 39 extends, driving the electric suction cup module 310 at its telescopic end to move upwards. Until the lower electric suction cup module 310 contacts the lower surface of the vacuum packaging bag and activates negative pressure adsorption, holding the lower surface of the packaging bag, the first electric telescopic rod 34 shortens, causing the rotating frame 33 to rotate upward from a vertical state to a horizontal state with the connecting shaft with the fixed frame 32 as the center, thereby rotating the vacuum packaging bag to a vertical downward state. At the same time as the rotating frame 33 rotates, the third electric telescopic rods 39 on the upper and lower sides shorten simultaneously, and the upper and lower electric suction cup modules 310 on the upper and lower sides pull the upper and lower edges of the packaging bag upward and downward respectively, completely closing the opening of the vacuum packaging bag. After the bag is fully opened, the fourth electric telescopic rod 313 extends, driving the truss 312 at its telescopic end to move downward. Under the constraint of the limit guide rail assemblies 311 on both sides, the truss 31 drives the material transfer unit 4 below to move downward synchronously until the discharge hopper 44 at the bottom of the material transfer unit 4 is inserted into the opening of the vacuum packaging bag. The fifth electric telescopic rod 316 extends, driving the bracket 315 in the slot frame 314 to move upward until the bracket 315 supports the bottom of the vacuum packaging bag, preventing the packaging bag from sagging and deforming due to its weight during subsequent filling.

[0038] Step 3: The operator activates the feeder 42, the sixth electric telescopic rod 49, the first motor 414, the second motor 418, the micro electric telescopic rod 420, and the vacuum pump 412 via the control console 5. The feeder 42 operates according to the preset quantitative release parameters, discharging the temporarily stored seafood material inside through the discharge hopper 44 into the pre-opened vacuum packaging bag below. After bagging, the fourth electric telescopic rod 313 shortens, driving the truss 31 and the material transfer unit 4 to move upward, causing the discharge hopper 44 to be pulled out from inside the packaging bag opening. The sixth electric telescopic rod 49 shortens, driving the connected rotating rod 48 to rotate upward. With the coordinated action of the rotating rods 48 on both sides, the mounting base 410 moves diagonally forward to directly above the vacuum packaging bag opening. The first motor 414 drives the second rotating seat 413 to rotate downward around the connecting shaft with the fixed seat 411, causing the outer shell 415 at the front end of the second rotating seat to change from a horizontal state to a vertical downward state, causing the suction needles on the left and right sides of the outer shell 415 to... 421 Aligns with the inside of the bag opening, the second motor 418 starts, driving the gear in its gear and rack assembly 419 to rotate. When the gear in the gear and rack assembly 419 rotates, it drives the meshing racks on the upper and lower sides to move in the opposite direction, thereby driving the second mounting base 417 connected to the rack to move outward under the constraint of the limiting component 416, so as to adjust the distance between the two micro electric telescopic rods 420 on the left and right sides, so that it is completely adapted to the width of the bag opening of the vacuum packaging bag, ensuring that the straw needle 421 can be inserted smoothly. After the distance is adjusted, the micro electric telescopic rod 420 extends, driving the straw needle 421 at the end to move downward, insert into the vacuum packaging bag and avoid the material, only contacting the liquid inside the bag. Then the vacuum pump 412 starts, generating negative pressure through the pipeline connected to the straw needle 421, and extracting the seafood soup or water that seeps out of the seafood material during the bagging process from the bag. The extracted liquid is transported to the external collection container through the pipeline for centralized treatment, thereby avoiding liquid residue from affecting the subsequent vacuum sealing effect.

[0039] Step 4: After the liquid extraction is completed, the miniature electric telescopic rod 420 shortens, pulling the suction needle 421 out of the packaging bag. The second motor 418, the first motor 414, and the sixth electric telescopic rod 49 move in reverse order, driving the gear rack assembly 419, the second rotating seat 413, and the rotating rod 48 to reset, so that the material transfer unit 4 returns to its initial position. The operator starts the transfer robotic arm 210, the horizontal moving platform 29, the vacuum packaging machine 28, the transfer conveyor line 6, the handling robotic arm 7, and the discharge output line 8 through the control console 5. The end gripping mechanism of the transfer robotic arm 210 grips and grabs the semi-finished product after it has been filled. At the same time, the electric suction cup modules 310 on the upper and lower sides release the negative pressure adsorption and loosen the fixation on the packaging bag. The first electric telescopic rod 34, the second electric telescopic rod 37, the third electric telescopic rod 39, the fourth electric telescopic rod 313, and the fifth electric telescopic rod 316 in the bagging execution component 3 move in reverse order. The action drives the rotating frame 33, electric suction cup module 310, truss 312 and bracket 315 to reset, waiting for the next operation. The horizontal moving platform 29 drives the transfer robotic arm 210 to move in the left and right direction to the front loading port of the vacuum packaging machine 28. The transfer robotic arm 210 puts the semi-finished product into the vacuum packaging machine. The vacuum packaging machine 28 closes the door and starts the vacuuming and heat sealing process. After the vacuum packaging machine 28 removes the remaining air in the bag, it seals the bag opening with a heat sealing strip to complete the vacuum sealing. After the vacuum sealing is completed, the vacuum packaging machine 28 opens the door, and the transfer robotic arm 210 takes out the sealed finished product and places it on the surface of the transfer conveyor line 6. The transfer conveyor line 6 transports the finished product to the right until it is transported to the gripping station of the handling robotic arm 7. The handling robotic arm 7 grabs a single finished product and moves it to the surface of the discharge output line 8. The discharge output line 8 starts and transports the finished product to the finished product storage location in the workshop.
