Description

Technical Field

[0001] The present invention mainly relates to the technical field of the production and packaging of sealed bags, and specifically provides a packaging device and a packaging method for the production and processing of double-ribbed sound bone sealed bags. Background Art

[0002] A sealed bag is a plastic bag that can be repeatedly sealed, which is made by blown film forming and hot cutting bag making. Sealed bags can be used for the internal and external packaging of various small items (jewelry, small hardware, toys). Self-sealing bags made of food-grade raw materials can store various small foods, tea, seafood, etc., with functions of moisture-proof, anti-odor cross-contamination, waterproof, insect-proof, and preventing things from scattering; the double-ribbed sound bone sealed bag adopts double sealing strips, and has a better sealing effect.

[0003] In the production process of plastic bags, the made plastic bags need to be packaged, that is, the plastic bags made by the bag making machine are sent into the plastic bag packaging equipment. Sealed bags generally adopt bag-in-bag packaging. First, several sealed bags are stacked, and then the stacked sealed bags are put into a packaging bag (sealed bag); the bag-in-bag packaging can fully ensure the safety of the sealed bags during transportation and is convenient for merchants to sell.

[0004] In the process of putting several stacked sealed bags into the packaging bag (sealed bag), the problems are as follows: the size of the sealed bags to be packaged is almost the same as that of the outer packaging sealed bag. When the stacked sealed bags to be packaged are pushed into the outer packaging sealed bag, they are likely to come into contact with the bag mouth of the outer packaging sealed bag, which not only easily causes folding, bending or curling, etc., but also makes the bagging work unable to proceed smoothly, seriously affecting the production speed. And when the size of the sealed bag changes, the packaging machine cannot be quickly adjusted according to the size of the sealed bag to be packaged. Summary of the Invention

[0017] A packaging method for the production and processing of double-ribbed sound bone sealed bags, using the packaging equipment for the production and processing of double-ribbed sound bone sealed bags as described above, includes the following steps:

[0018] S1. Debugging: According to the size of the sealed bag to be packaged, start the driving motor through the controller to change the rising height of the suction nozzle, the maximum distance after the left and right support strips are expanded, the maximum distance after the upper and lower support strips are expanded, and the size of the T-shaped plate member;

[0019] S2. Feeding: The sealed bags to be packaged are stacked and form stacks, and are fed one by one under the pushing mechanism through the first conveyor. The outer packaging sealed bags are fed under the bag mouth expanding mechanism through the second conveyor;

[0020] S3. Mouth expanding: After the suction nozzle sucks the outer packaging sealed bag and moves upward, the bag mouth of the outer packaging sealed bag is slightly opened. The mouth expanding strip extends into the inner part of the outer packaging sealed bag and moves to both sides to completely open the bag mouth of the outer packaging sealed bag;

[0021] 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 inner part of the outer packaging sealed bag by the push plate. Then, the pushing mechanism and the bag mouth expanding mechanism reset, and the first conveyor and the second conveyor are activated to enter the next working cycle.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) When the packaging operation is carried out, first, two suction nozzles suck the outer packaging sealed bag and move to initially vertically open the bag mouth of the outer packaging sealed bag; then, after the mouth expanding strips on the left and right mounting frames are inserted into the bag mouth of the outer packaging sealed bag, they continuously penetrate and separate inside the outer packaging sealed bag to horizontally expand both sides of the bag mouth of the outer packaging sealed bag; then, the two mouth expanding strips on the same mounting frame separate to ensure a certain opening height on both sides of the bag mouth of the outer packaging sealed bag to completely open the bag mouth of the outer packaging sealed bag; finally, the fourth electric push rod is activated to push the T-shaped plate to press on a stack 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 mouth expanding mechanism and the end head of the T-shaped plate are in contact. Therefore, when the sealed bag to be packaged is fed into the outer packaging sealed bag, the sealed bag to be packaged is not likely to contact the bag mouth of the outer packaging sealed bag. The third electric push rod is activated to push the push plate to move, and the push plate feeds 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 the bag mouth of the outer packaging sealed bag during the process of being pushed into the outer packaging sealed bag, and the packaging bagging work cannot proceed smoothly, avoiding affecting the production speed;

[0024] (2) If the size of the sealed bag to be packaged is larger, the corresponding outer packaging sealed bag is also larger. In a series of products, the larger the sealed bag, the larger its bag opening. To ensure that the sealed bags to be packaged do not come into contact with the bag opening of the outer packaging sealed bag during the process of being pushed into the outer packaging sealed bag, correspondingly, the degree of change in the opening of the bag opening expansion 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 this upper end surface facing the bag opening expansion mechanism comes into contact with the end head of the T-shaped plate member, the T-shaped plate member should also become larger accordingly. The oil liquid inside a certain accommodating groove will be squeezed into the adjusting oil liquid rod. The elongation of the adjusting oil liquid rod will push the pulling frame to move. The pulling frame will push the moving rack to move, causing the moving rack to rotate and drive the telescopic strip to rotate, making the expansion plates on both sides of the ejector plate move outwards. At the same time, the movement of the moving rack will cause the ejector plate on the main sleeve to move outwards. The ejector plate and the expansion plates move outwards simultaneously, making the T-shaped plate member larger, ensuring the effective progress of the packaging operation.

[0025] (3) When the size of the sealed bag to be packaged becomes larger, the opening height of the bag opening of the outer packaging sealed bag also becomes larger. Start the driving motor, and the driving motor drives the screw rod to rotate, causing the lifting block to move upwards, making the first electric push rod move upwards. At the same time, the lifting block drives the top plate to move through the transmission rod, causing each piston block to move upwards, squeezing the oil liquid inside each accommodating groove into the pressing hydraulic rod, the telescopic oil liquid rod, the rotating oil liquid rod, and the adjusting oil liquid rod. Each of the above-mentioned oil liquid rods is internally provided with a spring. To ensure that when resetting, the oil liquid can be squeezed back into the accommodating groove again. The oil liquid inside a certain accommodating groove will be squeezed into the pressing hydraulic rod, causing the pressing hydraulic rod to elongate, making the pressing plate tilt. During the packaging operation, the first electric push rod and the movable electric push rod extend and contract simultaneously. When the movable electric push rod extends, it moves the pressing plate by pushing the sliding frame, causing the lifting rod to move downwards, preventing the suction nozzle from being unable to contact the outer packaging sealed bag after the first electric push rod moves upwards.

Detailed implementation manner

[0048] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0049] It should be noted that when an element is referred to as "fixed on" another element, it can be directly on the other element or there can be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are only for the purpose of illustration.

[0050] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention in this article are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0051] Please refer to the drawings with emphasis Figure 1 As shown, a packaging device for the production and processing of double-strength sound bone sealed bags includes a first conveyor 1, a second conveyor 2, a pushing mechanism 4 and a bag mouth expanding mechanism 3. The pushing mechanism 4 is installed on the first conveyor 1. The bag mouth expanding mechanism 3 is located between the first conveyor 1 and the second conveyor 2, and the output end of the pushing mechanism 4 faces the bag mouth expanding mechanism 3.

[0052] The sealed bags to be packaged are stacked and form stacks, and are sent one by one under the pushing mechanism 4 through the first conveyor 1. The outer packaging sealed bags are sent under the bag mouth expanding mechanism 3 through the second conveyor 2. The bag mouth expanding mechanism 3 expands the bag mouth of the outer packaging sealed bag. The pushing mechanism 4 pushes the stacked sealed bags to be packaged into the outer packaging sealed bag to complete the packaging operation. When the first conveyor 1 and the second conveyor 2 are started again to send away the packaged sealed bags, the next cycle of packaging operation starts at the same time.

[0053] By setting a central control (not shown in the figure), it is convenient to control the electrical components inside the equipment of the entire production line. The central control control circuit can be realized by simple programming by those skilled in the art and belongs to the common general knowledge in the art. Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0054] Please refer to the attached drawings with emphasis Figure 2 - Figure 7 As shown, the bag mouth expanding mechanism 3 includes a mounting frame body 101. A front side plate 102 is installed on one side of the mounting frame body 101. A first electric push rod 103 is installed on one side of the front side plate 102. A frame plate 104 is installed at the output end of the first electric push rod 103. Two suction nozzles 105 are slidably installed inside the frame plate 104. A lifting groove is provided inside the front side plate 102, and a lifting block 107 slides inside the lifting groove. The lifting block 107 is threadedly connected to a screw rod 106, and the screw rod 106 is rotatably installed inside the front side plate 102. An oil liquid box 108 is installed on the other side of the front side plate 102. A plurality of receiving grooves and a top plate are respectively provided at the upper and lower ends inside the oil liquid box 108. Each receiving groove contains oil liquid inside, and a piston block 110 slides inside each of them. Each piston block 110 is connected to the top plate through a connecting rod. 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 provided at the upper end of the mounting frame body 101. The output end of the driving motor 114 drives the screw rod 106 to rotate through two meshing bevel gears. 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 through a connecting plate, and the connecting plate is connected to the lifting rod 111. A pressing plate 112, a pressing hydraulic rod 113, a sliding frame and a movable electric push rod 116 are further provided on the side wall of the frame plate 104. The sliding frame slides left and right on the side wall of the frame plate 104. The movable electric push rod 116 is connected to the sliding frame. The pressing hydraulic rod 113 is installed inside the sliding frame. The lifting rod 111 is rotatably connected to a connecting ring, and the connecting ring is slidably connected to the pressing plate 112. A movable block is slidably installed at the upper end of the pressing plate 112, and the movable block is rotatably connected to the pressing hydraulic rod 113. The input end of the pressing hydraulic rod 113 is connected to a receiving groove inside the oil liquid box 108 through an oil liquid pipe.

[0055] When performing the packaging operation, the second conveyor 2 will send the outer packaging seal bag below the bag mouth opening mechanism 3, that is, the bag mouth of the outer packaging seal bag is directly below the two suction nozzles 105. The first electric push rod 103 and the movable electric push rod 116 are started simultaneously to push the frame plate 104 to move, so that the two suction nozzles 105 press on the upper side of the outer packaging seal bag. The air pump 115 is enabled and the two suction nozzles 105 suck air. The two suction nozzles 105 suck the outer packaging seal bag. The first electric push rod 103 resets, and the two suction nozzles 105 move upward and simultaneously initially open the bag mouth of the outer packaging seal bag;

[0056] If the specification of the sealed bag to be packaged is larger, the corresponding outer packaging seal bag is also larger. In a series of products, the larger the sealed bag, the larger its bag mouth. To ensure that the sealed bags to be packaged stacked do not contact the bag mouth of the outer packaging seal bag during the process of being pushed into the outer packaging seal bag, correspondingly, the degree of change in the opening of the bag mouth opening mechanism 3 should also change accordingly;

[0057] When the specification of the sealed bag to be packaged becomes larger, the opening height of the bag mouth of the outer packaging seal bag also becomes larger. Start the drive motor 114, and the drive motor 114 drives the screw rod 106 to rotate, causing the lifting block 107 to move upward, making the first electric push rod 103 move upward. At the same time, the lifting block 107 drives the top plate to move through the transmission rod 109, causing each piston block 110 to move upward, squeezing the oil in each accommodating groove 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 is internally provided with a spring to ensure that when resetting, the oil can be squeezed back into the accommodating groove. The oil in a certain accommodating groove will be squeezed into the pressing hydraulic rod 113, causing the pressing hydraulic rod 113 to elongate, making the pressing plate 112 tilt. When performing the packaging operation, the first electric push rod 103 and the movable electric push rod 116 elongate and shorten simultaneously. When the movable electric push rod 116 elongates, it moves the pressing plate 112 by pushing the sliding frame, causing the lifting rod 111 to move downward, preventing the suction nozzle 105 from being unable to contact the outer packaging seal bag after the first electric push rod 103 moves upward.

[0058] Please refer to the attached drawings with particular emphasis Figure 8 and Figure 9As shown in the figure, a fixed plate frame 201 is arranged at the upper end inside the mounting frame body 101. A rotating disk 202 is rotatably mounted at the center of the fixed plate frame 201. A telescopic hydraulic rod 204 and a rotating gear 203 connected to the axis of the rotating disk 202 are arranged at the upper end of the fixed plate frame 201. A pushing rack 205 is engaged with one side of the rotating gear 203. The telescopic end of the telescopic hydraulic rod 204 is connected to the pushing rack 205. The input end of the telescopic hydraulic rod 204 is communicated with a receiving groove inside an oil box 108 through an oil pipe. Two arc grooves 206, two limiting frames 207 and two moving plates 208 are arranged at the lower end of the fixed plate frame 201. The two arc grooves 206 are respectively arranged on the left and right sides of the rotating disk 202. The two limiting frames 207 are respectively slidably mounted on the left and right sides of the rotating disk 202. An installation rod 210 is slidably arranged inside each limiting frame 207. The installation rod 210 also slides inside the arc groove 206. The two moving plates 208 are respectively slidably arranged on the front and back sides of the rotating disk 202. A second electric push rod 209 is installed on each moving plate 208. Each moving plate 208 is rotatably connected to an eccentric position of the rotating disk 202 by a rotating rod.

[0059] When performing the packaging operation, the two second electric push rods 209 are activated to extend, so that the extending end of the second electric push rod 209 contacts the limiting frame 207 and pushes the limiting frame 207 to move. The limiting frame 207 drives the installation rod 210 to move. Since the installation rod 210 slides inside the arc groove 206, therefore, the moving plate frame 301 connected to the installation rod 210 also moves obliquely forward accordingly. That is, after the support strips 302 on the left and right mounting frame bodies 101 are inserted into the bag mouth of the outer packaging seal bag, they continuously penetrate and separate inside the outer packaging seal bag, and the bag mouth of the outer packaging seal bag is opened.

[0060] When the specification of the seal bag to be packaged becomes larger, the opening width of the bag mouth of the outer packaging seal bag also becomes larger accordingly; the oil liquid inside a certain receiving groove will be squeezed into the telescopic hydraulic rod 204, so that the telescopic hydraulic rod 204 extends and pushes the pushing rack 205 to move. The movement of the pushing rack 205 causes the rotating gear 203 to rotate. 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, change the initial position of the second electric push rod 209, reduce the distance between the second electric push rod 209 and the limiting frame 207, and make the moving distance of the second electric push rod 209 pushing the limiting frame 207 larger, so that the opening width of the bag mouth of the outer packaging seal bag also becomes larger accordingly.

[0061] Please refer to the attached drawings for emphasis. Figure 8 - Figure 11As shown in the figure, symmetrically arranged moving plate frames 301 are respectively provided on the left and right sides inside the mounting frame body 101. The moving plate frames 301 are connected to the mounting rods 210 and are slidably connected to the limiting frames 207. On the opposite sides of the two moving plate frames 301, two upper and lower support strips 302 are provided. The lower support strip 302 is fixedly installed on the moving plate frame 301. A limiting groove 303 is provided on the lower support strip 302. A limiting block is slidably arranged inside the limiting groove 303. The limiting block is slidably connected to the left and right of the upper support strip 302. A swinging rod 304 is rotatably installed on one side of the upper support strip 302. An accommodation groove is provided inside the swinging rod 304. A rotating hydraulic rod 305 and a slidably installed driving block are arranged inside the accommodation groove. The input end of the rotating hydraulic rod 305 is connected to a containing groove inside the hydraulic oil box 108 through a hydraulic oil pipe. A cross bar 306 is rotatably installed on the driving block. The other end of the cross bar 306 is connected to the upper support strip 302.

[0062] When the swinging rod 304 cannot rotate downward, the cross bar 306 and the support strip 302 remain parallel. Power motors 307 are provided on the opposite sides of the two moving plate frames 301. The output ends of the power motors 307 drive the swinging rod 304 to rotate through pulleys, belts and a number of gears.

[0063] When performing the packaging operation, the support strips 302 on the left and right mounting frame bodies 101 expand both sides of the bag mouth of the outer packaging sealing bag. At the same time, the power motor 307 drives the swinging rod 304 to rotate upward through the transmission components, so that the cross bar 306 drives the connected support strip 302 to move. Since the cross bar 306 drives the connected support strip 302 to be slidably connected to the limiting block inside the limiting groove 303, the two support strips 302 on the same mounting frame body 101 move away from each other, ensuring that the expansion height on both sides of the bag mouth of the outer packaging sealing bag is certain and completely opening the bag mouth of the outer packaging sealing bag;

[0064] When the specification of the sealed bag to be packaged becomes larger, the expansion height of the bag mouth of the outer packaging sealing bag also becomes larger, so the expansion height on both sides of the bag mouth of the outer packaging sealing bag also becomes larger; the hydraulic oil inside a certain containing groove will be squeezed into the rotating hydraulic rod 305, so that the rotating hydraulic rod 305 drives the cross bar 306 to move. Therefore, when the swinging rod 304 rotates upward, the rising height of the cross bar 306 also becomes higher, so that after the bag mouth of the outer packaging sealing bag is expanded, the distance between the two support strips 302 on the same mounting frame body 101 moving away from each other becomes larger, that is, the expansion height on both sides of the bag mouth of the outer packaging sealing bag also becomes larger.

[0065] Please refer to the attached drawings for emphasis Figure 12 - Figure 15As shown in the figure, the pusher mechanism 4 includes a fixed frame body 401. On one side of the fixed frame body 401, there is a vertical plate 402. A third electric push rod 403 is connected between the fixed frame body 401 and the vertical plate 402. An adjustable hydraulic rod 404 is slidably installed on the vertical plate 402. The input end of the adjustable hydraulic rod 404 is connected to a receiving groove inside the hydraulic oil box 108 through a hydraulic oil pipe. On the vertical plate 402, there is also a fourth electric push rod 405 for pushing the adjustable hydraulic rod 404 to move. On the other side of the vertical plate 402, there is a push plate 406 connected by a connecting rod. A T-shaped plate member 407 is slidably installed on the push plate 406. The T-shaped plate member 407 includes a main sleeve 410. At one end of the main sleeve 410, a pulling frame 408 connected to the adjustable hydraulic rod 404 slides. At the other end of the pulling frame 408, there are two moving racks 409 located inside the main sleeve 410. Each moving rack 409 meshes with a moving gear 411. The other ends of the two moving racks 409 are connected to an ejecting plate 414 sliding inside the main sleeve 410. Both ends of the ejecting plate 414 are slidably connected to an extension plate 412. The axis of the moving rack 409 is connected to a telescopic bar 413, and the other end of the telescopic bar 413 is rotatably installed on the extension plate 412.

[0066] The unsealed bags to be packaged are stacked and form stacks. If a stack of unsealed bags to be packaged is not tightly pressed, it is difficult to be fed into the outer packaging sealed bag. When performing the packaging operation, the first conveyor 1 feeds a stack of unsealed bags to be packaged under the pusher mechanism 4. The fourth electric push rod 405 is activated to push the T-shaped plate member 407 against a stack of unsealed bags to be packaged. The upper end surface of the unsealed bag to be packaged, and this upper end surface faces the side of the bag mouth opening mechanism 3 and contacts the end head of the T-shaped plate member 407. Therefore, when the unsealed bag to be packaged is fed into the outer packaging sealed bag, the unsealed bag to be packaged is not likely to contact the bag mouth of the outer packaging sealed bag. The third electric push rod 403 is activated to push the push plate 406 to move. The push plate 406 feeds the unsealed bag to be packaged into the outer packaging sealed bag to form a package.

[0067] When the size of the unsealed bag to be packaged becomes larger, to ensure that the upper end surface of the unsealed bag to be packaged, and this upper end surface faces the side of the bag mouth opening mechanism 3 and contacts the end head of the T-shaped plate member 407, the T-shaped plate member 407 should also become larger accordingly. The hydraulic oil in a certain receiving groove will be squeezed into the adjustable hydraulic rod 404. The elongation of the adjustable hydraulic rod 404 will push the pulling frame 408 to move. The pulling frame 408 will push the moving rack 409 to move, causing the moving rack 409 to rotate and drive the telescopic bar 413 to rotate, making the extension plates 412 on both sides of the ejecting plate 414 move outwards. At the same time, the movement of the moving rack 409 will make the ejecting plate 414 on the main sleeve 410 move outwards. The ejecting plate 414 and the extension plates 412 move outwards simultaneously, making the T-shaped plate member 407 larger, ensuring the effective progress of the packaging operation.

[0068] Specific operation steps:

[0069] During the packaging operation, the outer packaging seal bag is sent under the bag mouth expanding mechanism 3 through the second conveyor 2, that is, the bag mouth of the outer packaging seal bag is located directly below the two suction nozzles 105. The first electric push rod 103 is activated to push the frame plate 104 to move, so that the two suction nozzles 105 press on the upper part of the outer packaging seal bag. The air pump 115 is enabled and the two suction nozzles 105 suck air, and the two suction nozzles 105 suck the outer packaging seal bag. The first electric push rod 103 resets, and the two suction nozzles 105 move upward and simultaneously initially open the bag mouth of the outer packaging seal bag;

[0070] The two second electric push rods 209 are activated 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. The limit frame 207 drives the mounting rod 210 to move. Since the mounting rod 210 slides inside the arc groove 206, therefore, the moving plate frame 301 connected to the mounting rod 210 also moves obliquely forward. That is, after the mouth-opening strips 302 on the left and right mounting frames 101 are inserted into the bag mouth of the outer packaging seal bag, they continuously penetrate and separate inside the outer packaging seal bag to open the bag mouth of the outer packaging seal bag;

[0071] The mouth-opening strips 302 on the left and right mounting frames 101 open both sides of the bag mouth of the outer packaging seal bag. At the same time, the power motor 307 makes the swing rod 304 rotate upward through the transmission component, so that the cross bar 306 drives the connected mouth-opening strips 302 to move. Since the cross bar 306 drives the connected mouth-opening strips 302 to be slidably connected to the limit blocks inside the limit groove 303, the two mouth-opening strips 302 on the same mounting frame 101 separate, ensuring a certain opening height on both sides of the bag mouth of the outer packaging seal bag and completely opening the bag mouth of the outer packaging seal bag;

[0072] After the packaging seal bags are stacked and form stacks, the first conveyor 1 sends a stack of packaging seal bags under the pushing mechanism 4. The fourth electric push rod 405 is activated to push the T-shaped plate member 407 to press on a stack of packaging seal bags, on the upper end surface of the packaging seal bags, and the side of the upper end surface facing the bag mouth expanding mechanism 3 contacts the end head of the T-shaped plate member 407. Therefore, when the packaging seal bags are sent into the outer packaging seal bag, the packaging seal bags are not easily in contact with the bag mouth of the outer packaging seal bag. The third electric push rod 403 is activated to push the push plate 406 to move. The push plate 406 sends the packaging seal bags into the outer packaging seal bag to form a package. The first conveyor 1 and the second conveyor 2 are enabled to enter the next working cycle.

[0073] When the specification of the sealed bag to be packaged becomes larger, the opening size of the outer packaging sealed bag also becomes larger; start the drive motor 114, the drive motor 114 drives the screw rod 106 to rotate, causing the lifting block 107 to move upward, making the first electric push rod 103 move upward. At the same time, the lifting block 107 drives the top plate to move through the transmission rod 109, causing each piston block 110 to move upward, squeezing the oil in each accommodating groove into the pressing hydraulic rod 113, the telescopic oil rod 204, the rotating oil rod 305, and the adjusting oil rod 404; the oil in a certain accommodating groove will be squeezed into the pressing hydraulic rod 113, causing the pressing hydraulic rod 113 to extend, making the pressing plate 112 tilt. When performing packaging operations, the first electric push rod 103 and the movable electric push rod 116 extend and retract simultaneously. When the movable electric push rod 116 extends, it moves the pressing plate 112 by pushing the sliding frame, causing the lifting rod 111 to move downward, preventing the suction nozzle 105 from not being able to contact the outer packaging sealed bag after the first electric push rod 103 moves upward;

[0074] The oil in a certain accommodating groove will be squeezed into the telescopic oil rod 204, causing the telescopic oil rod 204 to extend and push the pushing rack 205 to move. The movement of the pushing rack 205 causes the rotating gear 203 to rotate, 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, making the distance that the second electric push rod 209 pushes the limiting frame 207 move larger, so that the opening width of the outer packaging sealed bag also becomes larger accordingly;

[0075] The oil in a certain accommodating groove will be squeezed into the rotating oil rod 305, causing the rotating oil rod 305 to drive the cross bar 306 to move. Therefore, when the swing rod 304 rotates upward, the rising height of the cross bar 306 also becomes higher, making the distance between the two mouth-opening strips 302 on the same mounting frame body 101 larger after the outer packaging sealed bag opening is expanded, that is, the opening height on both sides of the outer packaging sealed bag opening also becomes larger accordingly;

[0076] At the same time, to ensure that the upper end surface of the sealed bag to be packaged, and the side of this upper end surface facing the bag opening expanding mechanism 3 contacts the end head of the T-shaped plate member 407, the T-shaped plate member 407 should also become larger; the oil in a certain accommodating groove will be squeezed into the adjusting oil rod 404, and the extension of the adjusting oil rod 404 will push the pulling frame 408 to move. The pulling frame 408 pushes the moving rack 409 to move, causing the moving rack 409 to rotate and drive the telescopic strip 413 to rotate, making the expansion plates 412 on both sides of the ejecting plate 414 move outward. At the same time, the movement of the moving rack 409 will make the ejecting plate 414 on the main sleeve 410 move outward. The ejecting plate 414 and the expansion plates 412 move outward simultaneously, making the T-shaped plate member 407 larger, ensuring the effective progress of the packaging operation.

[0078] S1. Debugging: According to the size of the sealed bag to be packaged, start the drive motor through the controller to change the rising height of the suction nozzle, the maximum distance after the left and right mouth-opening strips are expanded, the maximum distance after the upper and lower mouth-opening strips are expanded, and the size of the T-shaped plate;

[0079] S2. Feeding: The sealed bags to be packaged are stacked and formed into stacks, and are individually fed under the pushing mechanism through the first conveyor. The outer packaging sealed bags are fed under the bag mouth opening mechanism through the second conveyor;

[0080] S3. Mouth opening: After the suction nozzle sucks the outer packaging sealed bag and moves upward, the bag mouth of the outer packaging sealed bag is slightly opened. The mouth-opening strips extend into the inner part of the outer packaging sealed bag and move to both sides to completely open the bag mouth of the outer packaging sealed bag;

[0081] S4. Packaging: After the T-shaped plate presses on the sealed bag to be packaged, the sealed bag to be packaged is pushed into the inner part of the outer packaging sealed bag by pushing the push plate. Then, the pushing mechanism and the bag mouth opening mechanism are reset, and the first conveyor and the second conveyor are activated to enter the next working cycle.

Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
