Description

Technical Field

[0001] This invention relates to the field of food packaging machinery technology, and in particular to a secondary packaging device. Background Technology

[0002] A secondary packaging machine is a fully automatic packaging machine used to complete the packaging from small bags to large bags in one go, saving manpower, material resources and financial resources, reducing production costs and improving production efficiency.

[0003] Currently, existing secondary packaging machines lack a buffer compartment, resulting in low equipment efficiency. Even with a buffer lifting device, the purpose is merely to reduce the height from which multiple small bags of noodles fall into the larger packaging bag. However, the relatively high height of the buffer lifting device, combined with the height required to accommodate the secondary packaging bag at its base, increases the overall height of the secondary packaging equipment, increasing its size and space requirements. Furthermore, it increases the height the small bags of noodles are lifted, wasting power resources.

[0004] In summary, improving the speed of secondary packaging equipment and addressing its large space requirements are urgent issues that need to be addressed by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a secondary packaging device that has a reduced overall height, occupies less space, and has a lower lifting height for small bags of noodles.

[0023] The beneficial effects of this invention are as follows: the small bag noodle lifting assembly is located on the side of the frame, and it delivers the small bags of noodles to the upper discharge port of the bag feeding assembly. The bag feeding assembly is located below the small bag noodle lifting assembly, and it is used to deliver large packaging bags to the lower part of the small bag noodle buffer assembly. The small bag noodle buffer assembly is located below the discharge port of the small bag noodle lifting assembly, and it includes a buffer chamber with an opening and closing opening at the bottom. When the opening and closing opening is closed, it is used to buffer multiple small bags of noodles; when open, it is used to allow multiple small bags of noodles or a single small bag of noodles to fall. The bag opening and supporting assembly cooperates with the bag feeding assembly, and it is located below the small bag noodle buffer assembly. The bag opening and supporting assembly is used to open and expand the large packaging bags delivered to the lower part of the small bag noodle buffer assembly. The face-lifting assembly is located below the bag-opening and bag-supporting assembly. The face-lifting assembly includes a vertical rail and a face-lifting device. The face-lifting device is slidably connected to the vertical rail and can move up and down along the vertical rail. The face-lifting device includes two face-lifting rollers that can rotate inwards and move closer to each other, thereby pulling the outer edge of the large packaging bag inwards at a certain height, thus supporting the small face-lifting bags inside the large packaging bag.

[0024] In use, the secondary packaging equipment of this application lifts small bags of noodles to the discharge port via a small bag lifting device. The discharge port opens, temporarily storing the small bags of noodles in the buffer chamber of the buffer component. The process is repeated to buffer multiple small bags of noodles in the buffer chamber. During this buffering process, the secondary packaging equipment performs bag feeding, bag opening and supporting actions, and the two dragging rollers of the noodle lifting component gather at a certain height outside the large packaging bag. At this point, the opening and closing of the buffer chamber is opened, allowing multiple bags of noodles to descend into the large packaging bag by being dragged by the dragging rollers. Then, the opening and closing of the buffer chamber is not closed, and individual small packaging bags pass through the opening and fall directly into the large packaging bag. Each time a small packaging bag falls, the two dragging rollers move downwards a certain height. Once the large packaging bag is full, the above process is repeated.

[0025] As can be seen from the above process, the buffer bin of this application is a fixed buffer bin, which only buffers part of the noodles in the large packaging bag. The problem of the drop difference between the small packaged noodles and the large packaging bag is solved by the noodle lifting component. Therefore, the height of the buffer bin does not need to be set very high. The height of the buffer bin and the height of the large packaging bag at the bottom of the buffer bin will not be very high. Therefore, the overall height of the secondary packaging equipment of this application is low, the space occupied is small, and there is no need to lift the small bag of noodles too high, thus saving power resources.

Detailed Implementation

[0044] The core of this invention is to provide a secondary packaging device that has a reduced overall height, occupies less space, and has a lower lifting height for small bags of noodles.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please refer to Figures 1 to 15In one specific embodiment, the secondary packaging equipment provided by the present invention includes a frame 2, a small bag noodle lifting component 4 disposed on the side of the frame 2, a small bag noodle buffer component 7 disposed below the discharge port of the small bag noodle lifting component 4, a bag feeding component 3 disposed below the small bag noodle lifting component 4, a bag opening and supporting component 9 cooperating with the bag feeding component 3 and located below the small bag noodle buffer component 7, and a noodle dragging lifting component 6 disposed below the bag opening and supporting component 9. The small bag noodle buffer component 7 includes a buffer chamber 71, and the bottom of the buffer chamber 71 has an opening and closing opening.

[0047] The noodle lifting assembly 6 includes a vertical rail 63 and a noodle-pulling device 62 slidably connected to the vertical rail 63. The noodle-pulling device 62 includes two noodle-pulling rollers 623, which are capable of rotating inward and moving closer to each other.

[0048] In the above structure, the secondary packaging equipment includes a frame 2, a small bag noodle lifting component 4, a small bag noodle buffer component 7, a bag feeding component 3, a bag opening and supporting component 9, and a lifting component.

[0049] The small bag noodle lifting component 4 is located on the side of the frame 2. The small bag noodle lifting component 4 delivers the small bag noodles to the upper discharge port of the bag feeding component 3.

[0050] The bag feeding component 3 is located below the small bag noodle lifting component 4. The bag feeding component 3 is used to deliver the large packaging bag to the lower part of the small bag noodle buffer component 7.

[0051] The small bag noodle buffer component 7 is located below the discharge port of the small bag noodle lifting component 4. The small bag noodle buffer component 7 includes a buffer chamber 71, and the bottom of the buffer chamber 71 has an opening and closing opening. When the opening and closing opening is closed, it is used to buffer multiple small bags of noodles; when open, it is used to allow multiple small bags of noodles or a single small bag of noodles to fall.

[0052] The bag opening and supporting component 9 works in conjunction with the bag feeding component 3. The bag opening and supporting component 9 is located below the small bag noodle buffer component 7. The bag opening and supporting component 9 is used to open the large packaging bag sent to the bottom of the small bag noodle buffer component 7 and open an inlet that can ensure the entry of the small bag noodle.

[0053] The noodle-pulling lifting assembly 6 is located at the lower part of the bag opening and supporting assembly 9. The noodle-pulling lifting assembly 6 includes a vertical rail 63 and a noodle-pulling device 62. The noodle-pulling device 62 is slidably connected to the vertical rail 63 and can move up and down along the vertical rail 63. The noodle-pulling device 62 includes two noodle-pulling rollers 623. The two noodle-pulling rollers 623 can rotate inward and move closer to each other, thereby pulling the outer side of the large packaging bag inward at a certain height, thus supporting the small bag of noodles inside the large packaging bag.

[0054] When using the secondary packaging equipment of this application, small bags of noodles are lifted to the discharge port by the small bag lifting device. After the noodles are aligned at the feeding position, the discharge port opens, allowing the small bags of noodles to be temporarily stored in the buffer chamber 71 of the buffer component. Then, the above process is repeated to buffer multiple bags of small bags of noodles in the buffer chamber 71. During the buffering of multiple bags of small bags of noodles, the secondary packaging equipment completes the bag feeding, bag opening and supporting actions, and the action of the two dragging rollers 623 of the dragging lifting component 6 gathering at a certain height outside the large packaging bag. At this time, the opening and closing of the buffer chamber 71 is opened, allowing multiple bags of noodles to be dragged down into the large packaging by the dragging rollers 623. Then, the opening and closing of the buffer chamber 71 is not closed. At this time, a single small packaging bag passes through the opening and closing and falls directly into the large packaging. Each time a small packaging bag falls, the two dragging rollers 623 move downwards a certain height. When the large packaging bag is full, the above process is repeated.

[0055] As can be seen from the above process, the buffer bin 71 of this application is a fixed buffer bin 71, which only buffers part of the noodles in the large packaging bag. The problem of the drop difference between the small packaged noodles and the large packaging bag is solved by the noodle lifting component 6. Therefore, the height of the buffer bin 71 does not need to be set very high. The height of the buffer bin 71 and the height of the large packaging bag at the bottom of the buffer bin 71 will not be very high. Therefore, the overall height of the secondary packaging equipment of this application is low, the space occupied is small, and there is no need to lift the small bag of noodles too high, thus saving power resources.

[0056] In another, more reliable embodiment, based on the above embodiment, the noodle-pulling lifting assembly 6 includes a lifting drive belt 61 for driving the noodle-pulling device 62 to move up and down, and a lifting motor connected to the lifting drive belt 61. The noodle-pulling device 62 is fixedly connected to the lifting drive belt 61.

[0057] The noodle-pulling device 62 includes a transverse support plate 621, two rotating shafts 622 rotatably connected to the transverse support plate 621, a first gear set 624 fixedly connected to the back of the two rotating shafts 622 respectively, and a drive cylinder 625 fixedly on the transverse support plate 621. The front of the two gears of the first gear set 624 are fixedly connected to two noodle-pulling rollers 623 respectively, and the piston rod of the drive cylinder 625 is hinged to the end face of one gear.

[0058] In some embodiments, the noodle-pulling assembly 6 includes a vertical rail 63, a noodle-pulling device 62, a lifting drive belt 61, and a lifting motor. The noodle-pulling device 62 is slidably connected to the vertical rail 63 and fixedly connected to the lifting drive belt 61. The lifting motor drives the noodle-pulling device 62 to move up and down along the vertical rail 63 via the lifting drive belt 61.

[0059] The noodle-dragging device 62 includes a transverse support plate 621 and two rotating shafts 622 symmetrically rotatably connected to the transverse support plate 621. Gears are connected to the right side of each of the two rotating shafts 622, and the two gears mesh. Dough-dragging rollers 623 are fixedly connected to the outer edge of the left side of the two rotating shafts 622. The cylinder body of the drive cylinder 625 is hinged to the right side of the support plate. The piston rod of the drive cylinder 625 is hinged to the end face of one of the gears. The drive cylinder 625 drives the active gear to rotate inward, and the other gear meshing with it also rotates inward synchronously. At the same time, it drives the two dough-dragging rollers 623 to rotate inward and move closer to each other, so as to gather the outer side of the large packaging bag inward at a certain height, thereby supporting the small bags of noodles inside the large packaging bag. The connection is simple and easy to control.

[0060] In another more reliable embodiment, based on any of the above embodiments, the small bag noodle buffer assembly 7 includes two second opening and closing base plates 73 disposed at the bottom of the buffer compartment 71 and a second opening and closing drive member 72 for driving the two second opening and closing base plates 73 to open and close.

[0061] In some embodiments, the small bag noodle buffer assembly 7 includes a buffer compartment 71, two second opening and closing base plates 73, and a second opening and closing drive member 72. The two second opening and closing base plates 73 are disposed at the bottom of the buffer compartment 71, and the second opening and closing drive member 72 drives the two second opening and closing base plates 73 to open and close. When the two second opening and closing base plates 73 are closed, they are used to buffer multiple bags of small bags of noodles; when the two second opening and closing base plates 73 are open, they are used to allow multiple bags of small bags of noodles or single bags of small bags of noodles to fall. Optionally, the second opening and closing drive member 72 is two slide cylinders respectively connected to the two second opening and closing base plates 73, so that the opening and closing movement of the second opening and closing base plates 73 is relatively smooth.

[0062] In another more reliable embodiment, based on any of the above embodiments, the small bag noodle lifting assembly 4 includes an inclined conveyor belt, a horizontal conveyor belt connected to the inclined conveyor belt, and a feeding and leveling assembly 5 connected to the end of the horizontal conveyor belt.

[0064] In some embodiments, an inclined conveyor belt, a horizontal conveyor belt, and a feeding and leveling assembly 5 are included. The horizontal conveyor belt is connected to the inclined conveyor belt, which moves the small bags of noodles from a lower position to the higher position of the horizontal conveyor belt. The feeding and leveling assembly 5 is connected to the end of the horizontal conveyor belt, which feeds the small bags of noodles onto the feeding and leveling assembly 5. The discharge port of the small bag noodle lifting assembly 4 is located on the feeding and leveling assembly 5, facilitating control of the opening and closing of the discharge port.

[0065] The feeding and aligning assembly 5 includes a baffle 53, two aligning panels 52, an aligning drive 51 that drives the two aligning panels 52 to move closer or further apart, two first opening and closing base plates 54, and a first opening and closing drive 55 that drives the two first opening and closing base plates 54 to open and close. The baffle 53 is used to block the forward movement of the small bag of noodles. The two aligning panels 52 are symmetrically arranged behind the baffle 53. The aligning drive 51 is arranged in front of the baffle 53. The aligning drive 51 consists of two slide cylinders respectively connected to the two aligning panels 52. When the two first opening and closing base plates 54 are closed, they support the small bag of noodles. When the two first opening and closing base plates 54 are open, they allow the small bag of noodles to fall. Optionally, the first opening and closing drive 55 consists of two slide cylinders respectively connected to the two first opening and closing base plates 54.

[0066] In use, the small bag of noodles is lifted onto the first opening and closing bottom plate 54 of the feeding and aligning assembly 5 by the small bag of noodles lifting device. After being pushed by the two aligning panels 52, the end faces of the noodles are aligned. Then the first opening and closing bottom plate 54 is opened, so that the small bag of noodles is temporarily stored in the buffer compartment 71 of the buffer assembly.

[0067] In another more reliable embodiment, based on any of the above embodiments, the bag feeding assembly 3 includes a bag conveying device 31 and a rotary bag feeding device 32. The rotary bag feeding device 32 includes a connecting bracket 321 hinged to the frame 2, a rotary drive 327 that drives the connecting bracket 321 to rotate, two connecting arms 322 connected to the connecting bracket 321, a clamping cylinder 323 hinged to the upper inner side of the connecting arm 322, a second gear set 324 hinged to the lower part of the connecting arm 322 in the vertical direction, an upper clamping plate 326 connected to the upper gear, and a lower clamping plate 325 connected to the lower gear. The piston rod of the clamping cylinder 323 is hinged to the upper part of the upper clamping plate 326.

[0068] In some embodiments, the bag feeding assembly 3 includes a bag conveying device 31 and a rotary bag feeding device 32. The bag conveying device 31 has a specific structure that is a common conveying device in the prior art. The rotary bag feeding device 32 includes a connecting frame 12 and two connecting arms 322 symmetrically connected to the connecting frame 12. The connecting frame 12 is hinged to the frame 2 and connected to the rotary drive 327 on the frame 2. The upper inner side of the connecting arm 322 is hinged to the cylinder body of the clamping cylinder 323. The lower part of the connecting arm 322 is hinged to two meshing gears in the vertical direction. The upper gear is connected to the upper clamping plate 326, and the lower gear is connected to the lower clamping plate 325. The upper part of the upper clamping plate 326 is hinged to the piston rod of the clamping cylinder 323. When the clamping cylinder 323 shortens, the upper clamping plate 326 and the lower clamping plate 325 separate, allowing the upper part of the large packaging bag to enter its interval. When the clamping cylinder 323 extends, it clamps the large packaging bag. Then, the rotary drive 327 drives the connecting frame 12 to rotate 90 degrees as a whole, sending the large packaging bag into the lower part of the buffer compartment 71.

[0069] In another more reliable embodiment, based on any of the above embodiments, the bag opening and supporting assembly 9 includes suction cup devices symmetrically arranged at the bottom of the buffer compartment 71. The suction cup devices include a translation slide cylinder 911 and a plurality of suction cups 918 connected to the slider of the translation slide cylinder 911.

[0070] In some embodiments, the front and rear suction cups 918 slide toward the large packaging bag under the drive of the front and rear translational slide cylinders 911. The front and rear suction cups 918 respectively suck up the front and back of the large packaging bag, and then retract under the action of the translational slide cylinders 911, thereby sucking the large packaging bag open.

[0071] Based on any of the above embodiments, the bag opening and supporting assembly 9 further includes bag supporting devices 91 symmetrically arranged on the sides of the buffer compartment 71. The bag supporting device 91 includes a first bag supporting frame 917 connected to the frame 2 via a lifting slide cylinder 919, a second bag supporting frame 914 connected to the first bag supporting frame 917 via a first left and right slide cylinder 916, a second left and right slide cylinder 915 connected below the first left and right slide cylinder 916, and an outer clamping plate 913 connected to the second left and right slide cylinder 915.

[0072] In some embodiments, the bag opening and supporting assembly 9 further includes a bag supporting device 91 symmetrically arranged on the sides of the buffer compartment 71. The bag supporting device 91 includes a first bag supporting frame 917, which is connected to the frame 2 via a lifting slide cylinder 919 to control the lifting and lowering of the first bag supporting frame 917. A second bag supporting frame 914 is connected to the first bag supporting frame 917 via a first left and right slide cylinder 916. An inner clamping plate 912 is fixedly connected to the second bag supporting frame 914, and an outer clamping plate 913 is connected via a second left and right slide cylinder 915.

[0073] The lifting slide cylinder 919 first descends so that the outer clamping plate 913 and the inner clamping plate 912 are located inside and outside the large packaging bag. Then, the outer clamping plate 913 moves inward and together with the inner clamping plate 912 clamps the large packaging bag. Then, the second bag support frame 914 of the two bag support devices 91 moves outward respectively, and the bag support is completed.

[0074] Compared with the prior art, in this application, due to the addition of the buffer compartment 71, the rotating bag feeding device 32 does not have the space to rotate upwards by a large angle to fit onto the bag supporting device 91. Therefore, the bag supporting device 91 itself is configured to move downwards to clamp the large packaging bag via the lifting slide cylinder 919, and then move upwards to pull up the large packaging bag after clamping it. This configuration can reduce the height space occupied by the large packaging bag and further reduce the overall height of the secondary packaging equipment.

[0075] Based on any of the above embodiments, the bag opening and supporting assembly 9 is provided with a surface shifting conveyor assembly 8 at its lower part. The surface shifting conveyor assembly 8 includes a conveyor belt 85 and a synchronous surface blocking device. The synchronous surface blocking device includes a transverse connecting part 87, two vertical frames 84 connected to the transverse connecting part 87, and a reciprocating drive member 86 that drives the transverse connecting part 87 to move back and forth along the belt conveying direction. The transverse connecting part 87 is located at the lower part of the conveyor belt 85, and the two vertical frames 84 are located on both sides of the conveyor belt 85. The upper part of the two vertical frames 84 facing the conveyor belt 85 is provided with a baffle plate 83.

[0076] Sealing components are provided on both sides of the conveyor belt 85.

[0077] In some embodiments, the lower part of the bag opening and supporting assembly 9 is provided with a shifting conveyor assembly 8. The shifting conveyor assembly 8 includes a conveyor belt 85 and a synchronous baffle device. The synchronous baffle device includes a transverse connecting part 87, two vertical frames 84 connected to the transverse connecting part 87, and a reciprocating drive member 86 that drives the transverse connecting part 87 to move back and forth along the conveyor belt direction. The transverse connecting part 87 is located at the lower part of the conveyor belt 85, and the two vertical frames 84 are located on both sides of the conveyor belt 85. The upper part of the two vertical frames 84 facing the conveyor belt 85 is provided with a baffle plate 83. The reciprocating drive member 86 is a slide cylinder. The synchronous baffle device can move synchronously with the large packaging bag after it has been filled, preventing the large packaging bag from tilting to both sides. After the large packaging bag is delivered to the correct position, it can return, and the cycle can be repeated.

[0078] Based on the above implementation method, sealing components are also provided on both sides of the conveyor belt 85. The principle of sealing components is the same as that of sealing components in the prior art, and will not be described in detail here.

[0079] In another more reliable embodiment, based on any of the above embodiments, a noodle-pushing device 81 is provided on one side of the conveyor belt 85, and a noodle-discharging device 82 is provided on the other side. The noodle-pushing device 81 includes a noodle-pushing plate and a noodle-pushing cylinder for driving the noodle-pushing plate to move.

[0080] The rotating conveyor device 82 includes a rotating bracket 821 fixedly connected to the frame 2, a rotating support platform 824 fixedly connected to the inlet end of the rotating conveyor belt 822, a rotating conveyor belt 822 whose conveying surface is perpendicular to the support surface of the rotating support platform 824, and a rotating drive device for driving the rotating conveyor belt 822 to rotate.

[0081] The rotary drive device includes a first motor 827, a drive gear 826, a rotary shaft 823, a driven gear 825, and a gear belt. The first motor 827 is fixedly connected to the rotary support 821. The drive gear 826 is connected to the output shaft of the first motor 827. The rotary shaft 823 is rotatably connected to the rotary support 821. One end of the rotary shaft 823 is connected to the driven gear 825, and the other end is connected to the belt frame of the rotary conveyor belt 822. The drive gear 826 and the driven gear 825 are connected by a gear belt drive.

[0082] In another more reliable embodiment, based on any of the above embodiments, the rotary drive device further includes a second motor 829, a first support link 820, and a second support link 828. The second motor 829 is fixedly connected to the rotary bracket 821, and the output shaft of the second motor 829 is connected to the first support link 828.

[0083] One end of the connecting rod is fixedly connected to the side, and the other end of the first supporting connecting rod 820 is hinged to one end of the second supporting connecting rod 828. The other end of the second supporting connecting rod 828 is hinged to the belt frame of the rotating conveyor belt 822.

[0084] In some embodiments, when the first motor 827 drives the rotary conveyor belt 822 to rotate, the second motor 829 also rotates, and the belt frame of the rotary conveyor belt 822, supported by the second support link 828, rotates, thereby making the rotation of the rotary conveyor belt 822 and the rotary support platform 824 more stable.

[0085] In operation, when the filled large packaging bag moves to the left end of the conveyor belt 85, the pushing device 81 pushes the large packaging bag onto the optional support platform and abuts against the conveyor surface of the rotating conveyor belt 822. Then, the first motor 827 and the second motor 829 rotate, driving the optional conveyor belt 85 and the rotating support platform 824 to rotate. Finally, the rotating conveyor belt 822 itself rotates to transport the laid-down large packaging bag to the outlet. This ensures stable output of the large packaging bag in a laid-down position, meeting different output requirements.

[0086] Optionally, the rotating conveyor belt 822 is interrupted with a certain gap in the width direction so that tape can be applied to the top of the large packaging bag at the interrupted position.

[0087] In another more reliable embodiment, based on any of the above embodiments, the secondary packaging equipment includes an adhesive tape assembly 1. The adhesive tape assembly 1 includes a connecting frame 12 fixedly connected to the top of the frame 2, a first connecting rod 11 with its first end hinged to the upper part of the connecting frame 12, a second connecting rod 15 with its first end hinged to the lower part of the connecting frame 12, a third connecting rod 16 with its upper end hinged to the second end of the first connecting rod 11 and its middle part hinged to the second end of the second connecting rod 15, and a third connecting rod 16 connected to the first connecting rod 11 for driving the first connecting rod 11 to rotate... The connecting frame 12 has a rotating adhesive tape drive, an adhesive tape roll rod 113 fixedly connected to the upper part of the third link 16, a guide roller 114 rotatably set on the upper part of the third link 16, a support roller 111 rotatably set at the lower end of the third link 16, and a cutter 112 fixed to the end of the third link 16. The cutter 112 is located below the support roller 111 and away from the side of the large packaging bag. After the adhesive tape comes down from the adhesive tape roll rod 113, it passes around the rear side of the guide roller 114 and the front side of the support roller 111 in sequence.

[0088] In the above structure, the adhesive tape assembly 1 includes a connecting frame 12, a first connecting rod 11, a second connecting rod 15, a third connecting rod 16, an adhesive tape drive unit, an adhesive tape roll rod 113, a guide roller 114, a support roller 111, and a cutter 112.

[0089] The top of the connecting frame 12 is fixedly connected to the frame 2, and the position of the connecting frame 12 is fixed. The upper part of the connecting frame 12 is hinged to the first end of the first connecting rod 11, and the lower part is hinged to the first end of the second connecting rod 15. The second end of the first connecting rod 11 is hinged to the upper end of the third connecting rod 16, and the second end of the second connecting rod 15 is hinged to the middle part of the third connecting rod 16. The first connecting rod 11 is connected to an adhesive tape drive component, which can drive the first connecting rod 11 to rotate around the connecting frame 12.

[0090] A tape reel rod 113 is fixedly connected to the upper side of the third connecting rod 16, and the tape is fitted onto the tape reel rod 113. A guide roller 114 is rotatably mounted on the upper part of the third connecting rod 16, and a support roller 111 is rotatably mounted on the lower end of the third connecting rod 16. The guide roller 114 and the support roller 111 can rotate relative to the third connecting rod 16. After the tape comes down from the tape reel rod 113, it passes sequentially around the rear side of the guide roller 114 and the front side of the support roller 111. The guide roller 114 and the support roller 111 serve to guide and support the tape. A cutter 112 is fixed to the end of the third connecting rod 16. The cutter 112 is located below the support roller 111, closer to the support roller 111, and farther from the side of the large packaging bag than the support roller 111. It should be noted that in this application, "forward" refers to the side where the large packaging bag enters the adhesive tape assembly 1, and "backward" refers to the side where the large packaging bag exits the adhesive tape assembly 1.

[0091] In use, the large packaging bag is placed on the rotating conveyor belt 822 and moved from front to back, so that the third connecting rod 16 is located in the gap in the middle of the rear of the rotating conveyor belt 822. The lower part of the large packaging bag first touches the tape on the front side of the support roller 111. Then, the tape drive unit drives the first connecting rod 11 to rotate. The rotation of the first connecting rod 11 drives the third connecting rod 16 to lift up. While the tape roll is unwinding, the guide roller 114 and the support roller 111 rotate relative to the tape to guide the tape. The support roller 111 also rolls the tape onto the large packaging bag. As the third link 16 is lifted, the large packaging bag continues to move toward the side of the adhesive tape assembly 1 that discharges. When the height of the cutter 112 is higher than the large packaging bag by a certain amount, the tape between the support roller 111 and the large packaging bag comes into contact with the cutter 112, and the cutter 112 cuts the tape, thereby achieving tape adhesion on the upper surface of the large packaging bag, that is, the side of the large packaging bag that is laid down facing upwards. This allows the packaging to be transported smoothly while being tapered, enabling secondary sealing of the packaging and preventing the large packaging bag from not being properly heat-sealed. At the same time, different colored identification tapes can be applied to facilitate the differentiation of different types of noodles.

[0092] The adhesive tape assembly 1 described above is only a preferred embodiment and is not limited to it. Based on this, targeted adjustments can be made according to actual needs to obtain different implementation methods. The third link 16 is also provided with at least two winding rollers for wrapping the tape. The winding rollers are arranged sequentially from top to bottom between the guide roller 114 and the support roller 111.

[0093] In some embodiments, there are two winding rollers: an upper roller 115 and a lower roller 116. A guide roller 114, upper roller 115, lower roller 116, support roller 111, and cutter 112 are arranged sequentially from top to bottom on the third link 16. The lower roller 116 and cutter 112 are positioned close to the support roller 111. The support roller 111 protrudes backward from the third link 16, upper roller 115, and lower roller 116 towards the side of the large packaging bag. The tape descends from the tape roll and winds from the rear of the guide roller 114, the front of the upper roller 115, and the rear of the lower roller 116 to the front of the support roller 111. The tape is guided and taut by multiple rollers, preventing wrinkles, flipping, and displacement, ensuring the entire tape remains flat from the tape roll to the cutter 112.

[0094] Based on the above specific embodiments, the support roller 111 is closer to the side of the large packaging bag than the winding roller and the third link 16.

[0095] In some embodiments, the front side of the support roller 111 is closer to the side of the large packaging bag than the front side of the winding roller and the front side of the third link 16, ensuring that the large packaging bag comes into contact with the tape on the front side of the support roller 111 first.

[0096] Optionally, the diameter of the support roller 111 can be larger than the diameter of the winding roller, making it easier for the support roller 111 to protrude backward from the third link 16, and making it easier to ensure that the tape in front of the support roller 111 contacts the large packaging bag first. Of course, the diameter of the support roller 111 being larger than the diameter of the winding roller is only a preferred embodiment, not the only one. Alternatively, the third link 16 can protrude forward at the position where it connects to the support roller 111, and the connection position of the support roller 111 is closer to the front of the large packaging bag than the connection position of the winding roller.

[0097] In another more reliable embodiment, based on any of the above embodiments, a cantilever bracket 18 is fixedly connected to the rear of the third link 16, a flattening frame 19 is rotatably connected to the cantilever bracket 18, and a flattening roller 110 is rotatably connected to the flattening frame 19. The height of the flattening roller 110 is lower than the height of the cutter 112.

[0098] In some embodiments, a cantilever bracket 18 is fixedly connected to the rear of the third link 16, and a flattening frame 19 is connected to the cantilever bracket 18, with the flattening frame 19 rotatably connected to the cantilever bracket 18. A flattening roller 110 is connected to the other end of the flattening frame 19, and the flattening roller 110 and the flattening frame 19 are rotatably connected via a rotating shaft 622. The height of the flattening roller 110 is lower than the height of the cutter 112. After the cutter 112 cuts the tape, the flattening roller 110 can roll under its own weight at the tape application position on the large packaging bag, flattening the tape on the large packaging bag, increasing the connection strength between the tape and the large packaging bag, and ensuring a more secure and flat tape connection.

[0099] In another more reliable embodiment, based on any of the above embodiments, the length of the second link 15 is less than the length of the first link 11.

[0100] In some embodiments, the length of the second link 15 is shorter than that of the first link 11. When the first link 11 rotates and drives the third link 16 to lift, it will also drive the third link 16 to rotate towards the side closer to the large packaging bag, making it easier for the tape between the support roller 111 and the large packaging bag to hit the cutter 112, thereby facilitating the cutting of the tape.

[0101] In another more reliable embodiment, based on any of the above embodiments, the adhesive tape drive includes a telescopic cylinder 13 and a drive rod 14. The cylinder body of the telescopic cylinder 13 is fixedly connected to the connecting frame 12. The piston of the telescopic cylinder 13 is hinged to one end of the drive rod 14, and the other end of the drive rod 14 is fixedly connected to the middle of the first connecting rod 11. The piston of the telescopic cylinder 13 extends and retracts in the horizontal direction, and the linear motion of the piston of the telescopic cylinder 13 drives the first connecting rod 11 to rotate. The connection method is simple, there is a driving arm, and the driving is easy. It does not require a motor drive at the pivot 622 of the first connecting rod 11, reducing the difficulty of arranging the drive component.

[0102] In another more reliable embodiment, based on any of the above embodiments, the tape roll rod 113 is coaxially arranged with the hinge axis of the third link 16 and the first link 11.

[0103] The guide roller 114 is rotatably mounted on the hinge shaft between the third link 16 and the second link 15.

[0104] In some embodiments, the hinge shaft of the third link 16 and the first link 11 extends out of the side plate of the third link 16, and the tape roll rod 113 is equivalent to an extended section of the hinge shaft of the third link 16 and the first link 11. By using the hinge shaft of the third link 16 and the first link 11 as the tape roll rod 113, the structure is simplified and each component is fully utilized.

[0105] The guide roller 114 is mounted on the hinge shaft of the third link 16 and the second link 15. The guide roller 114 rotates on the hinge shaft of the third link 16 and the second link 15. The guide roller 114 is connected by the hinge shaft of the third link 16 and the second link 15, making the structure simpler.

[0106] Based on the above specific embodiments, the two ends of the third link 16 are single-side plates, the middle part is a double-side plate, the two ends of the hinge shaft of the third link 16 and the second link 15 are connected at the double-side plates, and the tape roll rod 113, the winding roller and the support roller 111 are all cantilevered on the single-side plate.

[0107] In some embodiments, the tape reel rod 113, the winding roller, and the support roller 111 are all cantilevered, and the tape is connected from one side of the cantilever to the tape reel rod 113 and the roller, making it convenient for the tape to be wound in when first used.

[0108] Based on the above specific embodiments, the winding roller includes an upper roller 115 and a lower roller 116, and the third connecting rod 16 has a recess 17 between the upper roller 115 and the lower roller 116.

[0109] In some embodiments, the lower roller 116 is closer to the support roller 111, and the third link 16 has a forward recess 17 between the upper roller 115 and the lower roller 116 to avoid the upper part of the large packaging bag, so that the upper side of the large packaging bag contacts the tape on the front side of the support roller 111 first, and the middle part of the upper part of the large packaging bag is not stuck to the tape, which facilitates the rolling guidance between the lower roller 116 and the tape.
