[0002] Lobster is rich in protein, zinc, iodine, selenium and other trace elements. It has high nutritional value and delicious taste. It is one of the most popular aquatic products. Lobster is rich in magnesium, which can reduce the cholesterol content in the blood, prevent hypertension and myocardial infarction, and has a good protective effect on the cardiovascular system. Lobster contains high selenium, which can resist carcinogens in the body and enhance the body's immunity. Lobster is rich in nutrients, soft in texture, and easily digested and absorbed by the human body. It has a good conditioning effect on people who are weak and recovering from a serious illness. Because lobster meat has certain nutritional value, lobster is becoming more and more popular.

[0003] After searching, the publication number is: CN 218022270 U. A packaging device for processing lobster tails is proposed. In this case, the lobster tails in the packaging box are flattened by a baffle to prevent the lobster tails from piling up after entering the packaging box. The device uses a first auxiliary component to make the cotton cloth layer wipe the water at the top edge of the packaging box, and at the same time uses a hot air blower to generate hot air to dry the water at the top edge of the packaging box to avoid hollowing and loose packaging during packaging. However, it cannot achieve the purpose of vacuum packaging of the packaging box, so that the shelf life after packaging is shorter than that of vacuum packaging, and the packaging box needs to be placed manually on the packaging line, which not only has low packaging efficiency, but also easily causes the packaging box to overturn, affecting packaging. Therefore, it is necessary to propose a packaging device for processing lobster tails to solve the above problems. Summary of the invention

[0004] The invention aims to provide a packaging device for processing lobster tails, which can automatically perform vacuum packaging, has higher packaging efficiency and longer shelf life.

[0006] By adopting the above technical scheme, after the packaging box is placed on the packaging box placement plate, the packaging box placement plate is pushed to the left by the driving member, and at the same time, the vertical screw rod rotates, and the vertical guide rods on both sides limit the movable frame to move downward, so that the vacuum insertion tube corresponds to the height of the packaging box, and after moving to the packaging position, the initial capping is performed by the pressure capping structure, and then the vacuum extraction tube is pushed into the packaging box by the cylinder, and the packaging box is vacuumed by the vacuum pipe and the vacuum extraction tube by driving the vacuum pump. After the packaging box is vacuumized, the pressure capping is further performed by the pressure capping structure, thereby completing the vacuum packaging operation of the packaging box, and the packaging efficiency is higher and the shelf life is longer.

[0007] The present invention is further configured as follows: the driving member includes a first motor installed at the right end of the packing frame, the output end of the first motor is installed with a transverse screw rod threadably matched with the packing box placement plate, and both sides of the packing box placement plate are slidably matched with the packing frame.

[0008] By adopting the above technical solution, the first motor drives the transverse screw to rotate, pushing the packaging box placement plate to translate toward the packaging frame, thereby facilitating the transportation of the packaging boxes to be packaged.

[0009] The present invention is further configured as follows: sliders are installed on both sides of the packaging box placement plate, the inner walls on both sides of the packaging rack are provided with sliding grooves adapted to the sliders, the other end of the transverse screw rod is provided with a main bevel gear, the lower end of the vertical screw rod is provided with a slave bevel gear meshing with the main bevel gear, and the packaging box placement plate is provided with a plurality of placement grooves for placing lobster packaging boxes.

[0010] By adopting the above technical solution, the cooperation of the slider and the slide groove can improve the stability of the packaging box placement plate in conveying the packaging box. During the conveying process, the transverse screw drives the main bevel gear to rotate, and the engagement drives the slave bevel gear to rotate, so that the vertical screw rotates, thereby controlling the lifting and lowering of the vacuum tube, so that when the packaging box is conveyed to the packaging position, the vacuum tube also moves down to the same height of the packaging box, making the subsequent vacuuming more convenient.

[0011] The present invention is further configured as follows: the pressure cover structure includes two fixed blocks installed on the left side of the packaging frame, a second motor is arranged on the fixed block on one side, a rotating plate is installed at the output end of the second motor, two electric push rods are installed on the rotating plate, a pressure plate is installed between the output ends of the two electric push rods, and a plurality of suction cups are equidistantly installed on the pressure plate.

[0012] By adopting the above technical solution, the suction cup sucks the upper packaging box cover, and then the second motor drives the rotating plate to rotate, so that the sucked packaging box cover rotates downward and corresponds to the position of the packaging box, and the packaging box cover is pressed down onto the packaging box by driving the electric push rod. After vacuuming, it is pressed down again to complete the entire packaging operation.

[0013] The present invention is further configured as follows: a lifting plate is slidably provided on the side of the pressure plate away from the suction cup, a sliding column connected to the lifting plate is installed on each suction cup, and a first spring is sleeved on the outside of the sliding column.

[0014] By adopting the above technical solution, when the suction cup pushes the packaging box cover downward, the packaging box cover is buffered and pressed by the first spring in cooperation with the sliding operation of the sliding column and the pressing plate, and its sealing performance is better.

[0015] The present invention is further configured as follows: the unloading mechanism includes a rotating screw, a limit rod and four vertical plates for connecting the rotating screw and the limit rod, which are arranged above the packaging rack; a third motor connected to the end of the rotating screw is installed on one of the vertical plates; the external thread of the rotating screw is provided with a movable plate slidably connected to the limit rod; a plurality of push plates for pushing the packaging box on the conveying rack to the packaging box placement plate are installed at the lower end of the movable plate; and a precise unloading mechanism is also provided on the packaging rack.

[0016] By adopting the above technical solution, the third motor drives the rotating screw to rotate, and under the guidance of the limit rod, the movable plate is pushed to move left, thereby driving the push plate to push the packaging box on the conveying rack onto the packaging rack.

[0017] The present invention is further configured as follows: the precise unloading mechanism comprises a guide plate arranged at the upper end of the packaging rack and parallel to the conveying rack, a plurality of unloading troughs are installed on a side of the guide plate away from the conveying rack, and a flap mechanism is arranged in the unloading trough.

[0018] By adopting the above technical solution, the push plate first pushes multiple packing boxes into the feed chute and is located on the flip mechanism. The flip mechanism then makes the packing boxes fall vertically from the feed chute to the placement slot of the packing box placement plate below, thereby preventing the packing boxes from tipping over and facilitating subsequent rapid batch packaging operations.

[0019] The present invention is further configured as follows: the flap mechanism comprises a rotating plate installed in each material discharge chute and a connecting shaft connecting several rotating plates, and a linkage component is provided between the connecting shaft and the rotating screw rod.

[0020] By adopting the above technical solution, when the screw rod rotates and moves the push plate to the leftmost end, the packing box is pushed above the rotating plate. When the push plate is controlled to reset, the rotating plate is flipped through the linkage component, so that the packing box above falls vertically and accurately falls into the placement groove of the packing box placement plate. No manual intervention is required, and the packaging efficiency is greatly improved.

[0021] The present invention is further configured as follows: the linkage component includes torsion springs arranged at both ends of the connecting shaft, a horizontal plate is installed between the two vertical plates on one side, a ratchet is rotatably arranged on the horizontal plate, the movable plate is provided with a rack and a telescopic push rod connected to the rack at one end close to the ratchet, a synchronous wheel is arranged on the same side of the ratchet and the connecting shaft, and a synchronous belt is arranged between the two synchronous wheels.

[0022] By adopting the above technical solution, when the movable plate moves to the leftmost end, the telescopic push rod is compressed and pushes the rack to adapt to the ratchet. When the movable plate starts to move right and reset, the rack pushes the ratchet to rotate, and the connecting shaft is driven to rotate through the synchronous wheel and the synchronous belt, so that the rotating plate flips over and the packaging box falls into the placement groove of the packaging box placement plate. When the rack is disengaged from the ratchet, the torsion of the torsion spring rotates, so that the rotating plate is reset, thereby facilitating continuous packaging operations.

[0023] The present invention is further configured as follows: the telescopic push rod includes three sleeves installed below the end of the movable plate, a connecting rod connected to the rack is slidably provided at the bottom of each sleeve, an extrusion spring connected to the connecting rod is installed in the sleeve, and a movable block slidably connected to the side wall of the sleeve is installed at the upper end of the connecting rod.

[0024] By adopting the above technical solution, when the movable plate drives the rack to move left, the connecting rod moves upward in the sleeve, compressing the extrusion spring so that the rack does not push the ratchet to rotate. When driving the rack to move right, the coupling with the ratchet drives it to rotate, so that the packaging box is thrown down vertically.

[0025] The beneficial effects of the present invention are:

[0026] 1. The present invention, after the packaging box is placed on the packaging box placement plate, the driving member pushes the packaging box placement plate to move left, and at the same time the vertical screw rotates, and the vertical guide rods on both sides limit the movable frame to move downward, so that the vacuum insertion tube corresponds to the height of the packaging box, and after moving to the packaging position, the pressure capping structure is used for preliminary pressure capping, and then the pressure capping tube is pushed by the cylinder to be inserted into the packaging box, and the vacuum pump is driven to vacuumize the packaging box by the vacuum pipe and the vacuum insertion tube, and after the packaging box is vacuumized, the pressure capping structure is used for further pressure capping, thereby completing the vacuum packaging operation of the packaging box, and the packaging efficiency is higher and the shelf life is longer, so that the packaging needs can be better met.

[0027] 2. The present invention drives the rotating screw to rotate by the third motor, and under the guidance of the limit rod, pushes the movable plate to move left, thereby driving the push plate to push the packing box on the conveying rack to the packing rack, and then the packing box is vertically dropped from the unloading chute to the placement groove of the packing box placement plate below through the flip mechanism, so as to prevent the packing box from tipping over and facilitate the subsequent rapid batch packaging operation.

[0028] 3. In the present invention, when the movable plate moves to the leftmost end, the telescopic push rod is compressed and pushes the rack to adapt to the ratchet. When the movable plate starts to move right and reset, the rack pushes the ratchet to rotate, and the connecting shaft is driven to rotate through the synchronous wheel and the synchronous belt, so that the rotating plate is flipped, and the packaging box falls into the placement groove of the packaging box placement plate. When the rack is disengaged from the ratchet, the torsion of the torsion spring rotates, so that the rotating plate is reset, thereby facilitating continuous packaging operations and further improving its packaging efficiency.

[0040] After the packaging box is placed on the packaging box placement plate 3, the driving member pushes the packaging box placement plate 3 to move left, and at the same time, the vertical screw rod 51 rotates, and the vertical guide rods 52 on both sides limit the movable frame 53 to move down, so that the air extraction tube 57 corresponds to the height of the packaging box. After moving to the packaging position, the pressure capping structure 6 performs preliminary pressure capping, and then the cylinder 54 pushes the air extraction tube 57 to insert into the packaging box, and the air extraction pump 56 is driven to vacuum the packaging box through the air extraction tube 58 and the air extraction tube 57. After the packaging box is vacuumized, the pressure capping structure 6 further presses the packaging box, thereby completing the vacuum packaging operation of the packaging box, and its packaging efficiency is higher. The packaging box has a high quality and long shelf life. The first motor 59 drives the transverse screw rod 510 to rotate, pushing the packaging box placement plate 3 to translate toward the packaging frame 2, so as to facilitate the transportation of the packaging box to be packaged. The cooperation of the slider 511 and the slide groove can improve the stability of the packaging box placement plate 3 in transporting the packaging box. During the transportation process, the transverse screw rod 510 drives the main bevel gear 512 to rotate, and drives the slave bevel gear 513 to rotate through engagement, so that the vertical screw rod 51 rotates, thereby controlling the lifting and lowering of the vacuum tube 57, so that when the packaging box is transported to the packaging position, the vacuum tube 57 also moves down to the same height of the packaging box, making the subsequent vacuuming more convenient.

[0041] like Figure 2 , Figure 4 As shown, the pressure cover structure 6 includes two fixed blocks 61 installed on the left side of the packaging frame 2, and a second motor 62 is arranged on the fixed block 61 on one side, and a rotating plate 63 is installed on the output end of the second motor 62, and two electric push rods 64 are installed on the rotating plate 63, and a pressure plate 65 is installed between the output ends of the two electric push rods 64, and a plurality of suction cups 66 are equidistantly installed on the pressure plate 65, and a lifting plate 67 is slidably arranged on the side of the pressure plate 65 away from the suction cup 66, and a sliding column 68 connected to the lifting plate 67 is installed on each of the suction cups 66, and a first spring 69 is sleeved on the outside of the sliding column 68.

[0042] The suction cup 66 sucks the upper packaging box cover, and then the second motor 62 drives the rotating plate 63 to rotate, so that the sucked packaging box cover rotates downward and corresponds to the position of the packaging box, and the electric push rod 64 is driven to press the packaging box cover down onto the packaging box. After vacuuming, it is pressed down again to complete the entire packaging operation. In the process of the suction cup 66 pushing the packaging box cover to move downward, the first spring 69 is used for buffering, and the sliding column 68 and the pressing plate 65 are used for sliding operation, so that the packaging box cover is buffered and pressed, and its sealing is better.

[0043] like Figure 5 , Figure 6As shown, the unloading mechanism 4 includes a rotating screw 41, a limiting rod 42 and four vertical plates 43 for connecting the rotating screw 41 and the limiting rod 42, which are arranged above the packaging frame 2. A third motor 44 connected to the end of the rotating screw 41 is installed on one of the vertical plates 43. The external thread of the rotating screw 41 is provided with a movable plate 45 slidably connected to the limiting rod 42. The lower end of the movable plate 45 is provided with several push plates 46 for pushing the packaging box on the conveying frame 1 to the packaging box placement plate 3. The packaging frame 2 is also provided with a precise unloading mechanism, which includes a guide plate 47 arranged at the upper end of the packaging frame 2 and parallel to the conveying frame 1. The guide plate 47 is provided with several unloading troughs 48 on the side away from the conveying frame 1, and a flip mechanism is provided in the unloading trough 48.

[0044] The third motor 44 drives the rotating screw 41 to rotate, and under the guidance of the limit rod 42, the movable plate 45 is pushed to move left, thereby driving the push plate 46 to push the packing box on the conveying rack 1 to the packing rack 2. The push plate 46 first pushes multiple packing boxes into the unloading chute 48 and is located on the flip mechanism. The flip mechanism then makes the packing box fall vertically from the unloading chute 48 to the placement slot of the packing box placement plate 3 below, so as to prevent the packing box from tipping over and facilitate subsequent rapid batch packaging operations.

[0045] like Figure 6 As shown, the flap mechanism includes a rotating plate 49 installed in each feed chute 48 and a connecting shaft 410 connecting several rotating plates 49, a linkage component is arranged between the connecting shaft 410 and the rotating screw 41, and the linkage component includes a torsion spring 411 arranged at both ends of the connecting shaft 410, a horizontal plate 412 is installed between the two vertical plates 43 on one side, a ratchet 413 is rotatably arranged on the horizontal plate 412, the movable plate 45 is provided with a rack 414 and a telescopic push rod connected to the rack 414 at one end close to the ratchet 413, a synchronous wheel 415 is arranged on the same side of the ratchet 413 and the connecting shaft 410, and a synchronous belt 416 is arranged between the two synchronous wheels 415.

[0046] When the screw rod 41 rotates and moves the push plate 46 to the leftmost end, the packing box is pushed to the top of the rotating plate 49. When the push plate 46 is controlled to reset, the rotating plate 49 is flipped through the linkage component, so that the upper packing box falls vertically and accurately falls into the placement groove of the packing box placement plate 3. No manual intervention is required, and its packaging efficiency is greatly improved. When the movable plate 45 moves to the leftmost end, the telescopic push rod is compressed and pushes the rack 414 to adapt to the ratchet 413. When the movable plate 45 starts to move right and reset, the rack 414 pushes the ratchet 413 to rotate, and the connecting shaft 410 is driven to rotate through the synchronous wheel 415 and the synchronous belt 416, so that the rotating plate 49 is flipped, and the packing box falls into the placement groove of the packing box placement plate 3. When the rack 414 is disengaged from the ratchet 413, the torsion of the torsion spring 411 is rotated, so that the rotating plate 49 is reset, thereby facilitating continuous packaging operations.

[0047] like Figure 7 As shown, the telescopic push rod includes three sleeves 417 installed below the end of the movable plate 45, and a connecting rod 418 connected to the rack 414 is slidably provided at the bottom of each sleeve 417. An extrusion spring 419 connected to the connecting rod 418 is installed in the sleeve 417, and a movable block 420 slidably connected to the side wall of the sleeve 417 is installed on the upper end of the connecting rod 418.

[0048] When the movable plate 45 drives the rack 414 to move left, the connecting rod 418 moves upward in the sleeve 417, compressing the extrusion spring 419, so that the rack 414 will not push the ratchet 413 to rotate. When driving the rack 414 to move right, it drives the ratchet 413 to rotate through the coupling, so that the packaging box is thrown vertically downward.
