[0002] The sealed bag is a resealable plastic bag made by film blowing and hot cutting. It can be used for inner and outer packaging of various small items (accessories, small hardware, toys). The ziplock bags produced with food-grade raw materials can store various small foods, tea, seafood, etc., and are moisture-proof, odor-proof, waterproof, insect-proof, and prevent things from scattering; the double-rib sealed bag uses double sealing strips for better sealing effect.

[0003] In the production process of plastic bags, the finished plastic bags need to be packaged, that is, the plastic bags made by the bag making machine are sent to the plastic bag packaging equipment.

[0014] A packaging method for producing and processing double-rib rib sealed bags, using the packaging equipment for producing and processing double-rib rib sealed bags, comprising the following steps: S1. Debugging: According to the size of the sealed bag to be packaged, the driving motor is started through the controller to change the rising height of the suction nozzle, the maximum spacing of the left and right support strips after expansion, the maximum spacing of the upper and lower support strips after expansion, and the size of the T-type plate; S2, feeding: the sealed bags to be packaged are stacked and formed into a pile, and are fed one by one to the bottom of the pushing mechanism through the first conveyor, and the outer packaging sealed bags are fed to the bottom of the bag opening mechanism through the second conveyor; S3, opening: the suction nozzle sucks the outer packaging sealed bag and moves upward to slightly open the bag opening of the outer packaging sealed bag. The opening opening strip extends into the inner part of the outer packaging sealed bag and moves to both sides to completely open the bag opening of the outer packaging sealed bag. S4, packaging: After the T-shaped plate is pressed on the sealed bag to be packaged, the sealed bag to be packaged is pushed into the outer packaging sealed bag by the push plate, and then the pushing mechanism and the bag opening mechanism are reset, the first conveyor and the second conveyor are enabled, and the next working cycle is entered.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) When the packaging operation is in progress, first, two suction nozzles suck the outer packaging sealed bag and move to initially open the bag opening vertically; then, the opening bars on the left and right mounting frames are inserted into the bag opening of the outer packaging sealed bag, and then they are continuously inserted into the inner part of the outer packaging sealed bag and separated, so as to open the two sides of the bag opening of the outer packaging sealed bag horizontally; then, the two opening bars on the same mounting frame are separated to ensure that the opening height of the two sides of the bag opening of the outer packaging sealed bag is constant, so as to completely open the bag opening of the outer packaging sealed bag; finally, the fourth electric push rod is started to push the T-shaped plate to press on a pile of sealed bags to be packaged. The upper end surface of the sealed bag to be packaged, and the side of the upper end surface facing the bag opening opening mechanism are in contact with the end portion of the T-shaped plate, so when the sealed bag to be packaged is sent to the outer packaging sealed bag, it is not easy for the sealed bag to be packaged to contact with the bag opening of the outer packaging sealed bag. The third electric push rod is started to push the push plate to move, and the push plate sends the sealed bag to be packaged into the inner part of the outer packaging sealed bag to form a package; the entire packaging process can ensure that the stacked sealed bags to be packaged do not contact with the bag opening of the outer packaging sealed bag during the process of being pushed into the outer packaging sealed bag, so that the packaging and bagging work cannot be carried out smoothly, thereby avoiding affecting the production speed; (2) If the specification of the sealed bag to be packaged is larger, the corresponding outer packaging sealed bag will also be larger. In the series of products, the larger the sealed bag, the larger its bag opening. To ensure that the stacked sealed bags to be packaged do not come into contact with the bag opening of the outer packaging sealed bag when being pushed into the outer packaging sealed bag, the degree of expansion of the bag opening opening mechanism should also change accordingly. At the same time, to ensure that the upper end surface of the sealed bag to be packaged and the side of the upper end surface facing the bag opening opening mechanism are in contact with the end of the T-shaped plate, the T-shaped plate should also become larger accordingly. The oil inside a certain accommodating groove will squeeze into the inside of the adjusting oil rod. The extension of the adjusting oil rod will push the pulling frame to move. The pulling frame pushes the moving rack to move, so that the moving rack rotates and drives the telescopic bar to rotate, so that the expansion plates on both sides of the ejector plate move outward. At the same time, the movement of the moving rack will cause the ejector plate on the main sleeve to move outward. The ejector plate and the expansion plate move outward at the same time, so that the T-shaped plate becomes larger, ensuring the effective implementation of the packaging operation. (3) When the size of the sealed bag to be packaged increases, the height of the bag opening of the outer packaging sealed bag also increases accordingly; the drive motor is started, and the drive motor drives the screw rod to rotate, so that the lifting block moves up, and the first electric push rod moves up. At the same time, the lifting block drives the top plate to move through the transmission rod, so that each piston block moves up, and the oil inside each receiving groove is squeezed into the pressure hydraulic rod, the telescopic oil rod, the rotating oil rod and the adjusting oil rod. Each of the above oil rods has a built-in spring to ensure that the oil can be squeezed back into the receiving groove when it is reset; the oil inside a certain receiving groove will be squeezed into the pressure hydraulic rod, so that the pressure hydraulic rod is extended and the pressure plate is tilted. When the packaging operation is performed, the first electric push rod and the movable electric push rod are extended and shortened at the same time. When the movable electric push rod is extended, the sliding frame is pushed to move the pressure plate, so that the lifting rod moves down, so as to avoid the suction nozzle being unable to contact the outer packaging sealed bag after the first electric push rod moves up.

Each receiving groove contains oil, and a piston block 110 is slidably arranged inside. Each piston block 110 is connected to the top plate through a connecting rod, and the lifting block 107 is connected to the top plate through a transmission rod 109. A driving motor 114 and an air pump 115 are arranged on the upper end of the mounting frame 101. The output end of the driving motor 114 drives the screw 106 to rotate through two mutually meshing bevel gears, and the output end of the air pump 115 is connected to the two suction nozzles 105 through an air pipe. A sliding groove is provided on the side wall of the frame plate 104, and a lifting rod 111 slides inside the sliding groove. The two suction nozzles 105 are connected by a connecting plate, and the connecting plate is connected to the lifting rod 111. The side wall of the frame plate 104 is also provided with a pressing plate 112, a pressing hydraulic rod 113, a sliding frame and a movable electric push rod 116. The sliding frame slides left and right on the side wall of the frame plate 104, and the movable electric push rod 116 is connected to the sliding frame. The pressing hydraulic rod 113 is installed inside the sliding frame.

The input end of the pressing hydraulic rod 113 is connected to a accommodating groove inside the oil box 108 through an oil pipe.

[0026] During the packaging operation, the second conveyor 2 will deliver the outer packaging sealed bag to the bottom of the bag opening opening mechanism 3, that is, the bag opening of the outer packaging sealed bag is located directly below the two suction nozzles 105, the first electric push rod 103 and the movable electric push rod 116 are started at the same time, pushing the frame plate 104 to move, so that the two suction nozzles 105 are pressed above the outer packaging sealed bag, the air pump 115 is started and the two suction nozzles 105 suck air, the two suction nozzles 105 suck the outer packaging sealed bag, the first electric push rod 103 is reset, the two suction nozzles 105 move up and at the same time preliminarily open the bag opening of the outer packaging sealed bag; If the specification of the sealed bag to be packaged is larger, the corresponding outer packaging sealed bag will also be larger. In the series of products, the larger the sealed bag, the larger its bag opening. In order to ensure that the stacked sealed bags to be packaged do not come into contact with the bag opening of the outer packaging sealed bag when being pushed into the outer packaging sealed bag, the degree of opening of the bag opening opening mechanism 3 should also change accordingly. When the size of the sealed bag to be packaged becomes larger, the height of the bag opening of the outer packaging sealed bag also increases accordingly; the drive motor 114 is started, and the drive motor 114 drives the screw 106 to rotate, so that the lifting block 107 moves up, and the first electric push rod 103 moves up. At the same time, the lifting block 107 drives the top plate to move through the transmission rod 109, so that each piston block 110 moves up, and the oil inside each receiving groove is squeezed into the pressing hydraulic rod 113, the telescopic oil rod 204, the rotating oil rod 305 and the adjusting oil rod 404. Each of the above oil rods has a built-in elastic The spring can squeeze the oil back into the receiving groove to ensure that it is reset; the oil in a certain receiving groove will squeeze into the pressure hydraulic rod 113, so that the pressure hydraulic rod 113 is extended, and the pressure plate 112 is tilted. When the packaging operation is carried out, the first electric push rod 103 and the movable electric push rod 116 are extended and shortened at the same time. When the movable electric push rod 116 is extended, the pressure plate 112 is moved by pushing the sliding frame, so that the lifting rod 111 moves downward, avoiding that after the first electric push rod 103 moves upward, the suction nozzle 105 cannot contact the outer packaging sealing bag.

[0027] Please refer to the attached pictures Figure 8 and Fig. 9 As shown, a fixed plate frame 201 is provided at the upper end of the mounting frame 101, a rotatable rotating disk 202 is provided at the center of the fixed plate frame 201, a telescopic oil rod 204 and a rotating gear 203 connected to the axis of the rotating disk 202 are provided at the upper end of the fixed plate frame 201, a pushing rack 205 is meshed on one side of the rotating gear 203, the telescopic end of the telescopic oil rod 204 is connected to the pushing rack 205, and the input end of the telescopic oil rod 204 is connected to a receiving groove inside the oil box 108 through an oil pipe. Two groups of arc grooves 206, two groups of limit frames 207 and two groups of movable plates 208 are arranged at the lower end of the fixed plate frame 201. The two groups of arc grooves 206 are respectively arranged on the left and right sides of the rotating disk 202, and the two groups of limit frames 207 are respectively slidably installed on the left and right sides of the rotating disk 202. A mounting rod 210 is slidably provided inside each group of limit frames 207, and the mounting rod 210 also slides inside the arc groove 206. The two groups of movable plates 208 are respectively slidably provided on the front and rear sides of the rotating disk 202, and a second electric push rod 209 is installed on each movable plate 208. Each movable plate 208 is rotatably connected to the rotating disk 202 at an eccentric position with a rotating rod.

[0028] When the packaging operation is performed, the two second electric push rods 209 start to extend, so that the extended ends of the second electric push rods 209 contact the limiting frame 207 and push the limiting frame 207 to move, and the limiting frame 207 drives the installation rod 210 to move. Since the installation rod 210 slides inside the arc groove 206, the movable plate frame 301 connected to the installation rod 210 also moves obliquely forward, that is, after the opening-opening strips 302 on the left and right installation frames 101 are inserted into the bag opening of the outer packaging sealing bag, they continue to penetrate deeper and separate inside the outer packaging sealing bag, so as to open the bag opening of the outer packaging sealing bag; When the specification of the sealed bag to be packaged becomes larger, the width of the bag opening of the outer packaging sealed bag will also increase accordingly; the oil inside a certain receiving groove will squeeze into the telescopic oil rod 204, causing the telescopic oil rod 204 to extend and push the rack 205 to move, pushing the rack 205 to move so that the rotating gear 203 rotates, and the rotating gear 203 drives the rotating disk 202 to rotate. The rotation of the rotating disk 202 will drive the moving plate 208 to move through the rotating rod, changing the initial position of the second electric push rod 209, and reducing the distance between the second electric push rod 209 and the limit frame 207, so that the second electric push rod 209 pushes the limit frame 207 to move. The width of the bag opening of the outer packaging sealed bag is also increased accordingly.

[0029] Please refer to the attached pictures Figure 8 - Fig.11 As shown, symmetrical movable plate frames 301 are respectively arranged on the left and right sides of the mounting frame 101, the movable plate frames 301 are connected to the mounting rod 210, and are slidably connected to the limit frame 207, and the upper and lower support strips 302 are arranged on the opposite sides of the two movable plate frames 301, the lower support strip 302 is fixedly mounted on the movable plate frame 301, a limit groove 303 is arranged on the lower support strip 302, a limit block is slidably arranged inside the limit groove 303, the limit block and the upper support strip 302 are slidably connected to the left and right, a rotatable swing rod 304 is arranged on one side of the upper support strip 302, a placement groove is arranged inside the swing rod 304, a rotating oil rod 305 and a slidably mounted driving block are arranged inside the placement groove, the input end of the rotating oil rod 305 is connected to a receiving groove inside the oil box 108 through an oil pipe, a cross bar 306 is rotatably installed on the driving block, and the other end of the cross bar 306 is connected to the upper support strip 302.

[0030] When the swing rod 304 cannot rotate downward, the cross bar 306 and the support strip 302 remain parallel, and the two movable plate racks 301 are both provided with a power motor 307 on the back side. The output end of the power motor 307 drives the swing rod 304 to rotate through a pulley, a belt and a plurality of gears.

[0031] When performing packaging operations, the opening bars 302 on the left and right mounting frames 101 open the two sides of the bag opening of the outer packaging sealed bag. At the same time, the power motor 307 rotates the swing rod 304 upward through the transmission component, so that the cross bar 306 drives the connected opening bars 302 to move. Since the cross bar 306 drives the connected opening bars 302 to slide with the limit blocks inside the limit grooves 303, the two opening bars 302 on the same mounting frame 101 are separated, ensuring that the opening heights of the two sides of the bag opening of the outer packaging sealed bag are constant, and the bag opening of the outer packaging sealed bag is completely opened. When the specification of the sealed bag to be packaged becomes larger, the opening height of the outer packaging sealed bag bag also increases, and then the opening height on both sides of the outer packaging sealed bag bag opening also increases; the oil inside a certain receiving groove will squeeze into the rotating oil rod 305, so that the rotating oil rod 305 drives the cross bar 306 to move. Therefore, when the swing rod 304 rotates upward, the rising height of the cross bar 306 also increases, so that after the bag opening of the outer packaging sealed bag is opened, the distance between the two opening strips 302 on the same mounting frame 101 becomes larger, that is, the opening height on both sides of the bag opening of the outer packaging sealed bag also increases.

[0033] The sealed bags to be packaged are stacked and formed into a pile. If a pile of sealed bags to be packaged is not tightly pressed, it is difficult to be sent into the outer packaging sealed bag. When the packaging operation is performed, the first conveyor 1 sends a pile of sealed bags to be packaged below the pushing mechanism 4, and the fourth electric push rod 405 is started to push the T-shaped plate 407 to press on the pile of sealed bags to be packaged. The upper end surface of the sealed bags to be packaged, and the side of the upper end surface facing the bag opening opening mechanism 3 is in contact with the end of the T-shaped plate 407. Therefore, when the sealed bags to be packaged are sent into the outer packaging sealed bag, the sealed bags to be packaged are not easy to contact with the bag opening of the outer packaging sealed bag. The third electric push rod 403 is started to push the push plate 406 to move, and the push plate 406 sends the sealed bags to be packaged into the inner part of the outer packaging sealed bag to form a package. When the specification of the sealed bag to be packaged becomes larger, in order to ensure that the upper end surface of the sealed bag to be packaged, and the side of the upper end surface facing the bag opening mechanism 3 are in contact with the end portion of the T-shaped plate 407, the T-shaped plate 407 should also become larger accordingly; the oil inside a certain accommodating groove will squeeze into the inside of the adjusting oil rod 404, and the extension of the adjusting oil rod 404 will push the pulling frame 408 to move, and the pulling frame 408 will push the moving rack 409 to move, so that the moving rack 409 rotates and drives the telescopic bar 413 to rotate, so that the expansion plates 412 on both sides of the ejection plate 414 move outward, and at the same time, the movement of the moving rack 409 will cause the ejection plate 414 on the main sleeve 410 to move outward, and the ejection plate 414 and the expansion plate 412 move outward at the same time, so that the T-shaped plate 407 becomes larger, ensuring the effective implementation of the packaging operation.

[0034] Specific steps: During the packaging operation, the outer packaging sealed bag is fed to the lower part of the bag opening opening mechanism 3 through the second conveyor 2, that is, the bag opening of the outer packaging sealed bag is located directly below the two suction nozzles 105, the first electric push rod 103 is started, and the frame plate 104 is pushed to move, so that the two suction nozzles 105 are pressed above the outer packaging sealed bag, the air pump 115 is started and the two suction nozzles 105 suck air, the two suction nozzles 105 suck the outer packaging sealed bag, the first electric push rod 103 is reset, the two suction nozzles 105 move up and at the same time preliminarily open the bag opening of the outer packaging sealed bag; The two second electric push rods 209 start to extend, so that the extended ends of the second electric push rods 209 contact the limit frame 207 and push the limit frame 207 to move, and the limit frame 207 drives the installation rod 210 to move. Since the installation rod 210 slides inside the arc groove 206, the movable plate frame 301 connected to the installation rod 210 also moves obliquely forward, that is, after the opening-opening strips 302 on the left and right installation frames 101 are inserted into the bag opening of the outer packaging sealing bag, they continue to penetrate deeper into the outer packaging sealing bag and separate from each other, so as to open the bag opening of the outer packaging sealing bag; The opening bars 302 on the left and right mounting frames 101 open the two sides of the bag opening of the outer packaging sealing bag. At the same time, the power motor 307 rotates the swing rod 304 upward through the transmission component, so that the cross bar 306 drives the connected opening bars 302 to move. Since the cross bar 306 drives the connected opening bars 302 to slide with the limit blocks inside the limit groove 303, the two opening bars 302 on the same mounting frame 101 are separated, ensuring that the opening height of the two sides of the bag opening of the outer packaging sealing bag is constant, and the bag opening of the outer packaging sealing bag is completely opened; The sealed bags to be packaged are stacked and form piles. The first conveyor 1 sends a pile of sealed bags to the bottom of the pushing mechanism 4. The fourth electric push rod 405 is started to push the T-shaped plate 407 to press on the pile of sealed bags to be packaged. The upper end surface of the sealed bags to be packaged, and the upper end surface facing the side of the bag opening opening mechanism 3 are in contact with the end of the T-shaped plate 407. Therefore, when the sealed bags to be packaged are sent to the outer packaging sealed bag, the sealed bags to be packaged are not easy to contact with the bag opening of the outer packaging sealed bag. The third electric push rod 403 is started to push the push plate 406 to move. The push plate 406 sends the sealed bags to be packaged into the inner part of the outer packaging sealed bag to form a package. The first conveyor 1 and the second conveyor 2 are enabled to enter the next working cycle.

[0035] When the size of the sealed bag to be packaged becomes larger, the size of the bag opening of the outer packaging sealed bag also becomes larger; the drive motor 114 is started, and the drive motor 114 drives the screw 106 to rotate, so that the lifting block 107 moves up, and the first electric push rod 103 moves up. At the same time, the lifting block 107 drives the top plate to move through the transmission rod 109, so that each piston block 110 moves up, and the oil inside each receiving groove is squeezed into the pressing hydraulic rod 113, the telescopic oil rod 204, the rotating oil rod 305 and the regulating oil Rod 404; the oil in a certain receiving groove will squeeze into the inside of the pressure hydraulic rod 113, so that the pressure hydraulic rod 113 is extended, and the pressure plate 112 is tilted. When the packaging operation is performed, the first electric push rod 103 and the movable electric push rod 116 are extended and shortened at the same time. When the movable electric push rod 116 is extended, the pressure plate 112 is moved by pushing the sliding frame, so that the lifting rod 111 moves downward, so as to prevent the suction nozzle 105 from being unable to contact the outer packaging sealing bag after the first electric push rod 103 moves upward; The oil in a certain receiving groove will squeeze into the telescopic oil rod 204, so that the telescopic oil rod 204 extends and pushes the rack 205 to move, pushing the rack 205 to move so that the rotating gear 203 rotates, and the rotating gear 203 drives the rotating disk 202 to rotate. The rotation of the rotating disk 202 drives the moving plate 208 to move through the rotating rod, changing the initial position of the second electric push rod 209, reducing the distance between the second electric push rod 209 and the limiting frame 207, so that the second electric push rod 209 pushes the limiting frame 207 to move a larger distance, thereby increasing the width of the bag opening of the outer packaging sealing bag; The oil in a certain receiving groove will squeeze into the rotating oil rod 305, so that the rotating oil rod 305 drives the cross bar 306 to move. Therefore, when the swing rod 304 rotates upward, the rising height of the cross bar 306 also increases, so that after the bag opening of the outer packaging sealed bag is opened, the distance between the two opening bars 302 on the same mounting frame 101 becomes larger, that is, the opening height of both sides of the bag opening of the outer packaging sealed bag is also increased; At the same time, in order to ensure that the upper end surface of the sealed bag to be packaged is in contact with the side of the bag opening opening mechanism 3 and the end portion of the T-shaped plate 407, the T-shaped plate 407 should also become larger accordingly; the oil inside a certain accommodating groove will squeeze into the inside of the adjusting oil rod 404, and the extension of the adjusting oil rod 404 will push the pulling frame 408 to move, and the pulling frame 408 will push the moving rack 409 to move, so that the moving rack 409 rotates and drives the telescopic bar 413 to rotate, so that the expansion plates 412 on both sides of the ejection plate 414 move outward, and at the same time, the movement of the moving rack 409 will cause the ejection plate 414 on the main sleeve 410 to move outward, and the ejection plate 414 and the expansion plate 412 move outward at the same time, so that the T-shaped plate 407 becomes larger, ensuring the effective implementation of the packaging operation.
