[0062] Support plates 715 are rotatably mounted on the two rotating shafts 74, gear cylinders 716 are penetrated and fixedly mounted on the two supporting plates 715, parallel shaft gears 717 meshing with the corresponding gear cylinders 716 are fixedly mounted on the two rotating shafts 74, and an adjustment mechanism is installed between the two rotating shafts 74 and the placement plate 65.

[0063] The adjustment mechanism includes a threaded rod 71 rotatably mounted on the inner wall of the placement plate 65. There are two threaded rods 71. Sliding blocks 72 are threadedly mounted on the two threaded rods 71, and the two sliding blocks 72 are fixedly connected to the corresponding moving blocks 73. A reciprocating screw 78 is penetrated and rotatably mounted in the placement plate 65. A toothed disc 79 is fixedly mounted on the reciprocating screw 78. A ball nut is matched with the reciprocating screw 78. There are two ball nuts. A slider 710 is fixedly mounted on one side of the two ball nuts, and a second rack 711 is fixedly mounted on the two sliders 710.

[0064] A support frame 66 is fixedly installed on the device body 1, and two support frames 66 are provided. The lower ends of the two support frames 66 are fixedly installed with a first rack 67 that cooperates with the toothed disk 79. A plate body 718 is fixedly installed on the device body 1, and two plate bodies 718 are provided. Guide grooves 719 are opened on the two plate bodies 718, and linearly evenly distributed tooth blocks 720 are fixedly installed on the two guide grooves 719.

[0065] When the packaging bag 12 containing articles needs to be vacuum packaged, the first servo motor 41 is started first. The operation of the first servo motor 41 drives the conveyor belt 5 to reciprocate from left to right through the cooperation of the round roller, the transmission rod 42 and the two rotating wheels 43 (such as Figure 1 When the conveyor belt 5 drives the upper carrier plate 61 to move to a suitable position (at this time, the toothed disc 79 on the carrier plate 61 is just meshed with the first rack 67 on the left side, as shown in the direction shown in the figure), the conveyor belt 5 drives the upper carrier plate 61 to move to a suitable position (at this time, the toothed disc 79 on the carrier plate 61 is just meshed with the first rack 67 on the left side, as shown in the figure). Figure 1 The packaging bag 12 containing the items can be placed on the supporting plate 61 manually. At the same time, in order to facilitate the subsequent vacuum sealing of the packaging bag 12 by the equipment, the open end of the packaging bag 12 needs to be placed on the corresponding placement plate 65, and the two sides of the open end of the packaging bag 12 are sleeved between the two corresponding fixing sleeve rods 713, so as to achieve the preliminary fixation of the packaging bag 12.

[0066] After the two packaging bags 12 are placed on the carrying plate 61 in sequence, the first servo motor 41 is restarted. At this time, the conveyor belt 5 drives the carrying plate 61 to move to the right side, and the first rack 67 on the left side cooperates with the corresponding toothed disc 79 (such as Figure 1 The corresponding reciprocating screw 78 can be rotated. At this time, the rotation of the reciprocating screw 78 will cause the two second racks 711 to move to the right together (as shown in the direction) through the cooperation of the two ball nuts and the two sliders 710. Figure 7 direction shown).

[0067] from Figure 7As can be seen in the figure, during the movement, the second rack gear 711 on the left side will first mesh with the rotating gear 712 on the left rotating rod 77, and drive the leftmost clamping plate 714 to rotate counterclockwise with the left rotating rod 77 as the axis. When the second rack gear 711 on the left side moves and meshes with the gear cylinder 716 on the left rotating shaft 74, the gear cylinder 716 and the corresponding parallel axis gear 717 cooperate (combined with the gear cylinder 716). Figure 7 and Figure 8 It can be seen that gear blocks evenly distributed in an annular shape are provided on the inner wall and the outer wall of the gear cylinder 716. When the left second rack 711 moves to drive the rotating rod 77 to rotate counterclockwise, the second rack 711 will continue to move to drive the gear cylinder 716 to rotate counterclockwise. Since the gear blocks inside the gear cylinder 716 are in opposite directions to the teeth on the corresponding parallel-axis gear 717, when the gear cylinder 716 rotates counterclockwise, it can drive the corresponding rotating shaft 74 to rotate clockwise through cooperation with the parallel-axis gear 717. The clamping plate 714 on the left rotating shaft 74 can be driven to rotate clockwise, thereby realizing the relative rotation of the two corresponding clamping plates 714 on the left side, and cooperating with the corresponding fixed sleeve rod 713 to clamp and fix the two sides of the opening end of the corresponding packaging bag 12, which helps to improve the stability of the position of the packaging bag 12 during the movement of the conveyor belt 5 to transport the packaging bag 12, thereby helping to improve the effect of the subsequent vacuum packaging of the packaging bag 12 by the equipment;

[0068] When the second rack 711 on the right side moves, it will first drive the clamping plate 714 on the right side shaft 74 to rotate counterclockwise, and then drive the clamping plate 714 on the right side rotating rod 77 to rotate clockwise through cooperation with the right side rotating gear 712, so that the two corresponding clamping plates 714 on the right side can rotate relative to each other, and cooperate with the corresponding fixed sleeve rod 713 to clamp and fix the two sides of the opening end of the corresponding packaging bag 12.

[0069] In addition, when the corresponding two clamps 714 cooperate with the corresponding fixed sleeve rods 713 to clamp the two sides of the open end of the packaging bag 12, the corresponding two fixed sleeve rods 713 can play a role in propping up the open end of the packaging bag 12, which is helpful for the equipment to accurately evacuate and inflate the packaging bag 12 later, and can improve the subsequent vacuum sealing effect of the packaging bag 12 by the equipment to a certain extent. The effect of the corresponding two fixed sleeve rods 713 in propping up the open end of the packaging bag 12 helps to improve the flatness of the hot pressing seal of the packaging bag 12, improve the overall appearance of the packaging bag 12 after vacuum packaging, and can also further improve the subsequent vacuum packaging effect of the packaging bag 12 by the equipment to a certain extent.

[0070] When the two clamping plates 714 cooperate with the fixing sleeve rods 713 to clamp and fix the two sides of the opening of the packaging bag 12, the supporting plate 61 on which the packaging bag 12 is placed is forced to move to the right end of the two plates 718 and continues to move (such as Figure 2direction), through the right front side inclined surfaces of the two guide grooves 719 (such as Fig. 9 The two rotating shafts 64 can drive the corresponding fixing frame 63 and the placing plate 65 to gradually move upward (as shown in the direction of FIG. Fig. 9 In the direction shown, during this process, the two corresponding adjustment rods 62 will be gradually stretched), and during this process, the packaging bag 12 will gradually rotate upward (as shown in FIG. Fig. 9 direction shown).

[0071] When the multiple tooth blocks 69 on the two rotating shafts 64 move to mesh with the corresponding tooth blocks 720 and continue to move, the two rotating shafts 64 will be driven by the force to drive the corresponding placement plates 65 to rotate downward (such as Fig. 9 The placing plate 65 and the packaging bag 12 are perpendicular to the conveyor belt 5 as a whole. At this time, the articles placed in the packaging bag 12 will be concentrated at the lower end of the packaging bag 12 under the action of gravity, which can effectively improve the fit between the articles and the packaging bag 12 and reduce the occurrence of wrinkles in the packaging bag 12 due to uneven filling of the articles, which helps to further improve the vacuum sealing effect of the subsequent packaging bag 12.

[0072] When the conveyor belt 5 drives the carrier plate 61 on which the packaging bag 12 is placed to move to the middle position of the two plates 718, the toothed disc 79 on the next carrier plate 61 just moves to mesh with the first rack 67 on the left side (such as Figure 1 In the direction shown), the operation of the first servo motor 41 needs to be stopped at this time, so that the remaining packaging bags 12 that need to be vacuum treated can be placed on the next carrier plate 61, and the equipment can vacuum seal the packaging bags 12 between the two plates 718, so as to achieve the continuity of the vacuum packaging of the placed packaging bags 12 by the equipment, and ensure the working effect of the equipment.

[0073] In addition, if it is necessary to vacuum pack packaging bags 12 of different widths (such as Figure 2 As shown in the figure, the width of the packaging bag 12 refers to the distance between the left front end and the right rear end of the packaging bag 12). By manually rotating the threaded rod 71, the corresponding sliding block 72 can drive the corresponding moving block 73 and the rotating shaft 74 to move closer to or away from the corresponding rotating rod 77, thereby increasing or reducing the distance between the corresponding two fixed sleeve rods 713. In this way, the device can clamp and fix the open ends of packaging bags 12 of different widths, which can effectively improve the flexibility of the device.

[0074] like Figure 1 , Fig. 9 - Fig.18 As shown, the heat sealing component includes grooves (not shown in the figure but not labeled) respectively opened on two partitions 91. Fig.12As can be seen in the figure, electric telescopic rods 93 are fixedly mounted on the two trough bodies, push plates 94 are fixedly mounted on the two electric telescopic rods 93, and the two push plates 94 are sealed and slidably mounted on the corresponding trough bodies, elastic baffles 95 are fixedly mounted between the two push plates 94 and the corresponding trough bodies, and two elastic baffles 95 are provided, heat sealing plates 96 are fixedly mounted on the two push plates 94, and elastic pressure plates 97 (drawn but not marked in the figure, from Fig.15 can be seen in ).

[0075] The air induction component includes a support plate fixedly mounted on a fixed disk 101, a motor 102 fixedly mounted on the support plate, a rod body fixedly mounted on the driving end of the motor 102, a fan 103 fixedly mounted on the rod body, a sealing member 105 mounted on the shaft via a one-way bearing, and a sealing member 2 106 fixedly mounted on the shaft.

[0076] The gas delivery assembly 8 includes an air delivery pipe 85 fixedly installed in the vacuum cover 3, the air delivery pipe 85 is fixedly connected to a guide tube 86, the guide tube 86 is fixedly connected to a plurality of tube bodies 87, the air delivery pipe 85 is fixedly connected to an air delivery pipe 88, and two air delivery pipes 88 are provided;

[0077] A limit plate is fixedly installed on the vacuum cover 3, and a gas filling machine 81 is fixedly installed on the limit plate. A delivery pipe 82 is fixedly connected between the gas filling machine 81 and the air delivery pipe 85, and the delivery pipe 82 is sealed and penetrated and fixedly installed on the vacuum cover 3.

[0078] The detection component 11 includes a spring telescopic rod 111 fixedly installed on the inner wall of the vacuum cover 3. There are two spring telescopic rods 111. A fixing plate 112 is fixedly installed between the two spring telescopic rods 111. A helium detector 113 is fixedly installed on the upper end of the fixing plate 112. A limit frame is fixedly installed on the inner wall of the vacuum cover 3, and an air bag 114 is fixedly installed in the limit frame.

[0079] When the conveyor belt 5 drives the carrying plate 61 with the packaging bag 12 to move to the middle position of the two plates 718, the first servo motor 41 stops running, and the two electric lifting plates 2 are started. At this time, the operation of the two electric lifting plates 2 will drive the vacuum cover 3 to move downward until the lower end of the vacuum cover 3 is tightly attached to the upper end of the conveyor belt 5 (such as Fig.10 Direction shown, and from Fig.11It can be seen that a slot matching with the two plates 718 is provided at the lower end of the vacuum hood 3. When the vacuum hood 3 continues to move downward and contacts the conveyor belt 5, one end of the two plates 718 is sealed and engaged in the corresponding slot, thereby ensuring that a sealed environment is formed at the lower end of the vacuum hood 3).

[0080] When the vacuum cover 3 stops moving downward, the two electric telescopic rods 93 are started first. At this time, the operation of the two electric telescopic rods 93 will drive the two push plates 94, the two heat sealing plates 96 and the two elastic pressing plates 97 to move closer to each other. Since the distance between the two elastic pressing plates 97 is slightly smaller than the distance between the two heat sealing plates 96, the two elastic pressing plates 97 will first contact the left and right sides of the packaging bag 12 (such as Fig.14 The two electric telescopic rods 93 are operated continuously to make the two elastic pressure plates 97 cooperate to squeeze the packaging bag 12, thereby effectively improving the fit between the left and right sides of the packaging bag 12 and the elastic pressure plates 97, and helping to improve the effect of the subsequent two heat sealing plates 96 cooperating to heat-press and seal the packaging bag 12, until the two heat sealing plates 96 are longitudinally fitted with the left and right sides of the packaging bag 12, and then the operation of the two electric telescopic rods 93 is stopped.

[0081] When the vacuum cover 3 is continuously forced to move downward, the front and rear ends of the two partitions 91 will be closely attached to the corresponding plate body 718 (such as Fig.12 As shown in the direction, when the two elastic pressure plates 97 cooperate to squeeze the left and right sides of the two packaging bags 12, the vacuum cover 3 can be divided into an upper and a lower area through the cooperation of the two partitions 91 and the push plate 94, the two heat sealing plates 96 and the two plate bodies 718.

[0082] After the two elastic pressure plates 97 cooperate to squeeze the left and right sides of the packaging bag 12, the vacuum pump 83 and the two motors 102 are started first. At this time, the operation of the vacuum pump 83 will extract part of the gas inside the packaging bag 12 through the cooperation of the exhaust pipe 84, the air supply pipe 85, the conduit 86, and the multiple tube bodies 87 (at this stage, the air pressure inside the packaging bag 12 will be slightly lower than the atmospheric pressure, but it is not enough to completely shrink the bag. The purpose is to make the air in the packaging bag 12 evenly distributed, reduce the local wrinkles of the packaging bag 12 caused by the low air pressure in the bag, and reduce the subsequent vacuum sealing effect of the packaging bag 12).

[0083] like Fig.14 As shown, when the lower end of the vacuum cover 3 is attached to the upper end of the conveyor belt 5 , the lower ends of the multiple tubes 87 are inserted into the corresponding packaging bags 12 , so that the packaging bags 12 can be accurately evacuated and supplied with gas through the cooperation of the multiple tubes 87 .

[0084] At the same time, through the cooperation of the exhaust pipe 84, the air supply pipe 85 and the two air supply pipes 88, part of the gas above the two partitions 91 and the push plate 94 can be extracted, and because the two vents 92 are in a ventilated state at this time, the two air supply pipes 88 cooperate in the exhaust process, and the gas below the partition 91 will be extracted through the two vents 92 (such as Fig.12 direction shown).

[0085] At the same time, the operation of the two motors 102 will drive the two fans 103 to rotate through the two rods. Since the blades on the two fans 103 are tilted upward at this time, the rotation of the two fans 103 will suck the gas below the two partitions 91 into the top of the two partitions 91, and push the gas above the two partitions 91 to move upward, which can help improve the effect and speed of the two air pipes 88 cooperating to extract the gas inside the vacuum cover 3. In addition, the rotation of the two fans 103 helps to promote the uniform distribution of airflow inside the vacuum cover 3, avoiding the airflow being too concentrated or sparse in certain areas, and the uniform airflow can help eliminate bubbles and folds inside the packaging bag 12, so that the packaging bag 12 can fit the article more smoothly and tightly during the vacuuming process, reducing the occurrence of poor sealing of the packaging bag 12 due to bubbles.

[0086] And combined Fig.12 and Fig.16 It can be seen that the initial tilting directions of the two fans 103 are set to correspond to the tilting directions of the corresponding air pipes 88 (the two fans 103 are symmetrically arranged), thereby further improving the effect of the two air pipes 88 on extracting the gas inside the vacuum cover 3.

[0087] When the blades on the two fans 103 are tilted upward, the convex surfaces of the blades on the fans 103 are located at the bottom, and the concave surfaces are located at the top (such as Fig.16 As shown in the direction, since the convex surface of the fan blade is smoother and the air resistance is smaller, the air flows faster on the convex surface of the fan blade, forming a low-pressure area. Since the air resistance on the concave surface of the fan blade is larger, the air flows slower on the concave surface of the fan blade, forming a high-pressure area. At this time, according to the principle of airflow, the air can flow from the high-pressure area (convex surface) to the low-pressure area (concave surface), forming a continuous airflow.

[0088] In addition, the part of the exhaust pipe 84 located between the vacuum hood 3 and the equipment body 1 is made of elastic material. The purpose is to facilitate the vacuum hood 3 to stretch or compress the exhaust pipe 84 when the two electric lifting plates 2 drive the vacuum hood 3 to move up and down, so that the exhaust pipe 84 moves along with it.

[0089] When the vacuum cover 3 and the packaging bag 12 inside it are pre-evacuated through the gas delivery component 8, the operation of the vacuum pump 83 is stopped first, and the gas filling machine 81, the helium detector 113, and the two second servo motors 104 are started at the same time. The operation of the gas filling machine 81 will cooperate with the existing helium storage tank to input helium into the packaging bag 12 through multiple tubes 87 until the packaging bag 12 expands to a certain extent. During the expansion process of the packaging bag 12, it can help to improve the uniformity of the contact between the packaging bag 12 and the items inside it, and reduce the gap between the packaging bag 12 and the items when the subsequent equipment performs the main evacuation of the packaging bag 12.

[0090] Two gas pipes 88 are each equipped with a valve (not shown in the figure). When the gas filling machine 81 starts running, by closing the two valves, helium can be accurately filled into the packaging bag 12 through the cooperation of the delivery pipe 82, the air pipe 85, the conduit 86 and the multiple tube bodies 87, thereby helping to increase the inflation speed of the packaging bag 12 and improve the efficiency of the equipment in vacuum packaging the packaging bag 12.

[0091] During operation, the gas filling machine 81 will accurately fill the helium in the existing helium storage tank into the packaging bag 12 after pressure regulation and flow control. When the packaging bag 12 is filled with an appropriate amount of helium, the equipment will automatically close the gas valve. Its internal components are all existing mature technologies and will not be further elaborated here.

[0092] The two partitions 91 cooperate with the two push plates 94 and the two heat-sealing plates 96 to divide the vacuum cover 3 into an upper and a lower area, and the lower end of the heat-sealed edge of the packaging bag 12 is concentrated at the lower end of the two partitions 91 and the two push plates 94 (such as Fig.14 As shown in the figure, when the gas filling machine 81 fills the packaging bag 12 with helium, the helium detector 113 can be used to simultaneously detect the sealing of the lower end of the packaging bag 12 (i.e., the lower end of the hot-pressed seal of the packaging bag 12). Since the packaging bag 12 inside the vacuum cover 3 is in a vertical state, the left and right sides of the packaging bag 12 are not blocked (such as Fig.18 As a result, the helium detector 113 can detect the packaging bag 12 comprehensively, which effectively improves the effect of the helium detector 113 on the sealing performance of the packaging bag 12 (such as Fig.18 direction shown).

[0093] Since the thermal conductivity of helium is different from that of air, the helium detector 113 determines the helium concentration by heating the gas through the sensor and monitoring the change in the thermal conductivity of the gas during operation. In addition, the internal components of the helium detector 113 are all existing equipment and will not be further elaborated here.

[0094] At the same time, during the process of pre-evacuating the vacuum cover 3 by the vacuum pump 83, the air pressure below the two partitions 91 will also decrease due to the continuous reduction of the gas in the space below the two partitions 91. Therefore, when the air pressure at the lower ends of the two partitions 91 is lower than the air pressure inside the airbag 114, the airbag 114 will begin to expand, and the restricted position frame will limit the movement of the airbag 114. During the expansion process, the airbag 114 will push the fixed plate 112 and the helium detector 113 to move to the right (such as Fig.18 The helium detector 113 moves to the middle of the two packaging bags 12, thereby effectively ensuring that the helium detector 113 performs a balanced sealing test on the left and right sides of the packaging bags 12.

[0095] At this time, the operation of the two second servo motors 104 will cause the two fans 103 to rotate downward (such as Fig.16 The second servo motor 104 drives the shaft to rotate clockwise (as shown in the direction shown in the figure), until the blades on the two fans 103 are tilted downward, the convex surfaces of the blades on the fan 103 are all located at the top, and the concave surfaces are all located at the bottom. At the same time, the second servo motor 104 drives the shaft to drive the second blocking member 106 thereon to rotate clockwise (as shown in the direction shown in the figure). Fig.16 In the direction shown, the corresponding one-way bearing is in a rotating state and will not rotate. Since the two fans 103 are symmetrically arranged, the operation of the other second servo motor 104 should drive the corresponding shaft to drive the second blocking member 106 thereon to rotate counterclockwise. The second blocking member 106 will block the upper end of the corresponding vent 92 during the rotational displacement process (such as Fig.16 Therefore, the rotation of the two fans 103 will blow the gas below the two partitions 91 downward (as shown in the direction of FIG. Fig.18 direction shown).

[0096] If the damaged portion of the packaging bag 12 is relatively small and the helium leakage is relatively small, the distance between the packaging bag 12 and the helium detector 113 and the shielding of the components inside the vacuum cover 3 will reduce the flow rate of the helium toward the location of the helium detector 113, thereby reducing the timeliness and sensitivity of the helium detector 113 in detecting the helium below the partition 91, that is, the sealing performance of the packaging bag 12. At this time, the rotation of the two fans 103 can accelerate the flow rate from below the partition 91 to the helium detector 113, which helps to improve the efficiency of the helium detector 113 in detecting the helium concentration below the two partitions 91, that is, improve the effect of the helium detector 113 in detecting the sealing performance of the packaging bag 12.

[0097] If the helium detector 113 detects helium leakage below the partition 91 , the helium detector 113 will sound an alarm to remind the staff to replace the broken packaging bag 12 .

[0098] A one-way exhaust pipe (not shown) is fixedly connected to the vacuum cover 3. When the two fans 103 rotate and cooperate to blow the gas below the partition plate 91 downward (such as Fig.18 In the direction shown), at this time, the part of the gas can be easily discharged through the one-way exhaust pipe, thereby effectively improving the vacuum effect at the lower end of the vacuum cover 3.

[0099] When the packaging bag 12 is filled with an appropriate amount of helium and the helium detector 113 does not sound an alarm, the gas filling machine 81 can be stopped, and the vacuum pump 83 and the two second servo motors 104 are restarted to start the main exhaust of the vacuum cover 3 and the upper ends of the two partitions 91 (such as Fig.12 At the same time, the operation of the two second servo motors 104 will drive the fan 103 to rotate and reset through the corresponding shafts. At this time, the rotation of the two fans 103 can further accelerate the speed and effect of extracting the gas from the inside of the vacuum cover 3 and the two partitions 91 through the two air pipes 88, which helps to improve the speed and effect of the equipment in vacuum packaging the packaging bag 12.

[0100] In the process that the second servo motor 104 drives the corresponding shaft to drive the fan 103 and the second blocking member 106 to rotate counterclockwise and reset, the shaft and the corresponding one-way bearing cooperate to make the blocking member 105 rotate counterclockwise together, until the blocking member 105 blocks the lower end of the corresponding vent 92 (such as Fig.16 In the direction shown), at this time, the cooperation between the two sealing members 105 and the two push plates 94 and the two heat sealing plates 96 can further accelerate the vacuum hood 3 to reach a vacuum state (the vacuum effect inside the vacuum hood 3 directly affects the packaging bag 12. If the vacuum effect inside the vacuum hood 3 is insufficient, air may remain in the packaging bag 12, resulting in a poor seal, which affects the safety and effectiveness of the product).

[0101] When the packaging bag 12 is tightly fitted with the items placed inside, the two electric telescopic rods 93 and the two heat sealing plates 96 can be started again, so that the two heat sealing plates 96 are close to each other to heat-press the left and right sides of the packaging bag 12 synchronously (such as Fig.14 In this way, the double-sided heat sealing effect of the packaging bag 12 can be achieved, which helps to improve the effect of heat-pressing the edge of the packaging bag 12.

[0102] After the two heat sealing plates 96 cooperate to complete the heat-pressing edge sealing of the packaging bag 12, the vacuum cover 3 is driven to move upward and reset (such as Fig.10 Then, the first servo motor 41 is restarted, so that the conveyor belt 5 drives the packaging bag 12 on which the vacuum seal is completed to continuously move rightward through the carrying plate 61 (as shown in the direction of FIG. 1 ). Figure 1As the bearing plate 61 starts to move rightward, the two rotating shafts 64 thereon are away from the corresponding toothed blocks 720. At this time, the corresponding torsion springs 68 have their own elastic force, so that the rotating shafts 64 can drive the corresponding placement plates 65 to rotate upward and reset (as shown in FIG. Fig. 9 until the placement plate 65 is rotated to a horizontal state.

[0103] When the placement plate 65 rotates to a horizontal state, the support plate 61 drives the fixing frame 63 and the placement plate 65 thereon to continuously move rightward (eg, Figure 1 When the guide groove 719 limits the movement of the corresponding rotating shaft 64, the two rotating shafts 64 cooperate to drive the fixing frame 63 and the placement plate 65 to gradually move downward and reset.

[0104] When the carrying plate 61 on which the packaging bag 12 is placed moves to the right side of the conveyor belt 5 (such as Fig.10 In the direction shown), at this time, the cooperation between the first rack 67 on the right side and the corresponding toothed disc 79 and the reciprocating screw 78 will cause the multiple clamping plates 714 to gradually rotate away from the corresponding fixed sleeve rod 713, so that the staff can take the vacuum-packed packaging bag 12 from the right end of the conveyor belt 5.

[0105] Usage: When the device is used to perform vacuum sealing on a packaging bag 12, the packaging bag 12 containing articles is first placed between the two corresponding fixed sleeve rods 713, and then the first servo motor 41 is operated to make the conveyor belt 5 convey the packaging bag 12 thereon from left to right (such as Figure 1 As shown in the direction, when the packaging bag 12 starts to move, the first rack 67 on the left cooperates with the clamping assembly 7, so that the multiple clamping plates 714 are forced to rotate, and cooperate with the corresponding fixing sleeve rods 713 to clamp and fix the open end of the packaging bag 12. When the packaging bag 12 is forced to move the right ends of the two plates 718 and continue to move (as shown in the direction shown in the direction), when the packaging bag 12 starts to move, the first rack 67 on the left cooperates with the clamping assembly 7, so that the multiple clamping plates 714 are forced to rotate, and cooperate with the corresponding fixing sleeve rods 713 to clamp and fix the open end of the packaging bag 12. Fig. 9 As shown in the direction, through the cooperation of the two guide grooves 719 and the corresponding rotating shaft 64, the open end of the packaging bag 12 can be gradually moved upward, and finally under the cooperation of gravity and a plurality of toothed blocks 720, the packaging bag 12 as a whole is perpendicular to the conveyor belt 5.

[0106] When the packaging bag 12 rotates to a vertical state, the operation of the first servo motor 41 is stopped, and the two electric lifting plates 2 are started to move the vacuum cover 3 downward until the lower end of the vacuum cover 3 is tightly fitted with the upper end of the conveyor belt 5 (such as Fig.10The vacuum pump 83 and the two motors 102 are then started. The operation of the vacuum pump 83 will first pre-evacuate the packaging bag 12 and the inner part of the vacuum cover 3, and then a proper amount of helium is filled into the packaging bag 12 through the gas filling machine 81. In this process, the air tightness of the packaging bag 12 can be detected through the cooperation of the air induction component and the detection component 11.

[0107] After the packaging bag 12 is filled with a proper amount of helium, the packaging bag 12 and the inner part of the vacuum cover 3 are subjected to main gas treatment by the vacuum pump 83 until the packaging bag 12 is tightly fitted with the items placed therein, and then the packaging bag 12 is heat-pressed and sealed by the heat-sealing component. After the equipment completes the vacuum sealing of the packaging bag 12, the open end of the packaging bag 12 can be released by the continuous operation of the conveyor belt 5 and the cooperation of the first rack 67 and the clamping assembly 7 on the right side, so that the staff can pick up the packaging bag 12 from the right end of the conveyor belt 5 (such as Fig.10 direction shown).

[0108] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
