[0066] Prepare the folded film adhered with the adhesive strip into a packaging bag;

[0067] Open the bag of the packaging bag;

[0068] Push the item to be packaged into the packaging bag;

[0069] Seal the bag opening of the packaging bag.

[0070] The beneficial effects of the present invention are as follows:

[0071] (1) By setting the adhesive tape feeding assembly, during the film feeding process of the folded film, the folded film and the adhesive tape sequentially bypass the film sticking assembly and the film pulling assembly, and the folded film and the adhesive tape are bonded between the upper film feeding roller and the lower film feeding roller. The bonding of the adhesive strip is completed during the film feeding process, without the need for additional manual or machine bonding, improving the packaging efficiency;

[0072] (2) The upper film feeding roller is fixed, and the lower film feeding roller rotates and can swing with the film feeding frame on the film feeding frame. When the first upper film pulling roller and the first lower film pulling roller are rotating, the film feeding frame will be slightly swung upward. When the first upper film pulling roller and the first lower film pulling roller stop rotating, the upper film feeding roller and the lower film feeding roller continue to rotate and feed the film. Since the film is getting longer, the film feeding frame will slightly swing downward under the action of its own gravity. When the first upper film pulling roller and the first lower film pulling roller rotate again, the film feeding frame will slightly swing upward again, repeating this cycle. The upper film feeding roller and the lower film feeding roller keep rotating, solving the problems of film deformation, wrinkle stacking and adhesion at the start and stop of the upper and lower film feeding rollers, and ensuring the stability of film feeding;

[0073] (3) The output end of the second film pulling driving part is connected to the second film pulling roller. The second film pulling roller provides a film pulling force at the same time. The second film pulling roller rotates and stops once like the first upper film pulling roller and the first lower film pulling roller. By setting the second film pulling roller, it is possible to prevent the entire film feeding frame from vibrating too violently and making abnormal noises;

[0074] (4) When making and sealing the bag, the first lower film pulling roller is synchronously linked with the heat sealing roller to keep the film pulling and heat sealing in synchronous linkage, ensuring the continuity and stability of bag making;

[0075] (5) The heat sealing knife is located in the water-cooling installation groove. After heat sealing, the heat sealing knife will lift up. Only at the position where the heat sealing knife contacts will there be a heat seal. Due to the existence of the water-cooling pressing block, the folded film will not adhere to the heat sealing knife when the heat sealing knife lifts up;

[0076] (6) The air suction conveying mechanism is divided into a first air suction conveyor belt and a second air suction conveyor belt. The first air suction conveyor belt and the second air suction conveyor belt correspond to the double-layer bag body and the turned edge of the packaging bag respectively, and the first air suction conveyor belt and the second air suction conveyor belt rotate synchronously, enabling synchronous conveying before heat sealing the bag mouth to ensure the conveying accuracy, and not interfering with each other during heat sealing or edge sealing, ensuring normal heat sealing or edge sealing;

[0077] (7) While the suction drive motor drives the first suction drive shaft to rotate, it drives the fourth linkage gear to rotate through the third linkage gear and the second linkage belt. The fourth linkage gear drives the fifth follower shaft to rotate, and the fifth follower shaft drives the pressure feed drive shaft to rotate through the universal coupling, so that the pressure feed conveyor belt rotates synchronously. The pressure feed conveyor belt rotates synchronously with the first suction conveyor belt. The upper layer of the double-layer packaging bag is in contact with the pressure feed conveyor belt, and the lower layer of the double-layer packaging bag is in contact with the first suction conveyor belt. When the pressure feed conveyor belt and the first suction conveyor belt rotate synchronously, the upper and lower layers of the double-layer packaging bag move synchronously. While flattening the packaging bag, the upper and lower sides of the packaging bag will not be misaligned and wrinkled or damaged; the first suction conveyor belt, the second suction conveyor belt and the pressure feed conveyor belt are synchronously linked, which ensures the stability of bag feeding while reducing structural redundancy;

[0078] (8) The bag-supporting drive assembly drives the bag-supporting nozzle to obliquely insert into the bag mouth of the packaging bag along the preset path. After inserting into the packaging bag, the bag-supporting nozzle is close enough to the lower layer of the packaging bag but does not contact the lower layer. Without affecting bag opening, only the upper layer of the packaging bag needs to reserve a length, and the lower layer of the packaging bag does not need to reserve a length, which can shorten the width of the packaging bag, reduce the packaging cost, and at the same time, after packing the items, the package is more compact.

[0115] In the present invention, by setting the adhesive tape feeding assembly 312, during the film feeding process of the folded film 1, the folded film 1 and the adhesive tape 2 sequentially pass around the film sticking assembly 32 and the film pulling assembly 33, and the folded film 1 and the adhesive tape 2 are bonded between the upper film feeding roller 322 and the lower film feeding roller 323. The bonding of the adhesive strip 21 is completed during the film feeding process, without the need for additional manual or machine bonding, improving the packaging efficiency.

[0116] Such as Figures 5 to 7As shown, during cutting and sealing, the folded film 1 that has been bonded needs to be cut and heat-sealed simultaneously to form individual packaging bags. Therefore, the film pulling assembly 33 pulls the film once and then stops to perform cutting and heat-sealing, and then pulls the film again after cutting and heat-sealing and stops again, repeating this cycle. At the same time, the upper film feeding roller 322 and the lower film feeding roller 323 of the film sticking assembly 32 also rotate once and then stop, continuously rotating once and then stopping. This causes two problems. The first is that there will be a greater pulling force during startup, which may deform the adhesive tape 2 or the film. The second problem is that when it stops, due to inertia, the folded film 1 and the adhesive tape 2 will be wrinkled and piled up at the entrance positions of the upper film feeding roller 322 and the lower film feeding roller 323, and even the bonding may be completed in advance, but this bonding is disordered and unqualified. To solve the above two problems, the film sticking driving part 321 continuously drives the upper film feeding roller 322 or the lower film feeding roller 323 to rotate. A film continuing assembly 34 is also provided on the film feeding frame 31. The film continuing assembly 34 includes n groups of upper film continuing rollers 341 and m groups of lower film continuing rollers 342. The upper film continuing rollers 341 are located above the upper film continuing rollers 341. A film continuing frame 343 is rotatably provided on the film feeding frame 31. The upper film continuing rollers 341 are rotatably provided on the film feeding frame 31, and the lower film continuing rollers 342 are rotatably provided on the film continuing frame 343, where m = n - 1. In this embodiment, n is equal to 4 and m is equal to 3. A second film pulling roller 344 is also rotatably provided above the upper film continuing rollers 341. The folded film 1 with the adhesive tape 2 attached thereto sequentially and cross-cyclically bypasses n groups of the upper film continuing rollers 341 and m groups of the lower film continuing rollers 342, and then bypasses the second film pulling roller 344 and is conveyed to the film pulling assembly 33.

[0117] In the embodiment of the present invention, the upper film continuation roller 341 is fixed, and the lower film continuation roller 342 rotates on the film continuation frame 343 and can swing with the film continuation frame 343. When the first upper film pulling roller 332 and the first lower film pulling roller 333 are rotating, the film continuation frame 343 will swing slightly upward. When the first upper film pulling roller and the first lower film pulling roller 333 stop rotating, the upper film feeding roller 322 and the lower film feeding roller 323 continue to rotate and feed the film. Since the film is getting longer, the film continuation frame 343 will swing slightly downward under its own gravity. When the first upper film pulling roller 332 and the first lower film pulling roller 333 rotate again, the film continuation frame 343 will swing slightly upward again, and this cycle repeats. The upper film feeding roller 322 and the lower film feeding roller 323 keep rotating, solving the problems of film deformation, wrinkling, stacking and adhesion during the start and stop of the upper film feeding roller 322 and the lower film feeding roller 323, and ensuring the stability of film feeding. Further, by arranging multiple groups of upper film continuation rollers 341 and lower film continuation rollers 342, the swinging amplitude of the film continuation frame 343 during start and stop is small; further, by arranging the second film pulling roller 344, a second film pulling driving part (not shown in the figure) is also arranged on the film feeding frame 31. The second film pulling roller 344 is rotatably arranged on the film feeding frame 31, and the output end of the second film pulling driving part is connected to the second film pulling roller 344. The second film pulling roller 344 provides a film pulling force at the same time. The second film pulling roller 344, like the first upper film pulling roller 332 and the first lower film pulling roller 333, rotates once and stops once. By arranging the second film pulling roller 344, it can prevent the entire film continuation frame 343 from vibrating too violently and generating abnormal noises.

[0118] As Figures 5 to 7 shown, a first reversing roller group 351, a second reversing roller 352, a third reversing roller 353, a fourth reversing roller 354 and a fifth reversing roller group 355 are also rotatably arranged on the film feeding frame 31; the first reversing roller group 351 and the second reversing roller 352 are arranged near the top of the film feeding frame 31, the fifth reversing roller group 355 is arranged near the bottom of the film feeding frame 31, and the third reversing roller 353 and the fourth reversing roller 354 are arranged at the middle position of the film feeding frame 31; the folded film 1 with the adhesive tape 2 already attached thereto bypasses the second film pulling roller 344 and then successively bypasses the first reversing roller group 351, the second reversing roller 352, the third reversing roller 353, the fourth reversing roller 354 and the fifth reversing roller group 355, and then is conveyed to the film pulling assembly 33. Specifically, in this embodiment, the functions of the first reversing roller group 351, the second reversing roller 352, the third reversing roller 353, the fourth reversing roller 354 and the fifth reversing roller group 355 are not only to make the film taut, but also to guide the direction and front-back of the film.

[0119] As Figures 5 to 7As shown, the folded film feeding assembly 311 includes a folded film feeding tray 3111, a first film feeding tension roller 3112, a second film feeding tension roller 3113, and a third film feeding tension roller 3114; the folded film 1 is sent out from the folded film feeding tray 3111 and then bypasses the first film feeding tension roller 3112, the second film feeding tension roller 3113, and the third film feeding tension roller 3114 in sequence. The first film feeding tension roller 3112, the second film feeding tension roller 3113, and the third film feeding tension roller 3114 keep the folded film 1 in tension. At the same time, the second film feeding tension roller 3113 can be selected as the deviation correction roller. With the cooperation of the deviation correction photoelectric eye, when the film is fed and deviation is detected, deviation correction can be performed. Regarding the principle of how to perform deviation correction, it belongs to the prior art and will not be elaborated here.

[0120] As Figures 5 to 7 shown, the adhesive tape feeding assembly 312 includes an adhesive tape feeding tray 3121, a first tension wheel 3122, a second tension wheel 3123, and a third tension wheel 3124; the adhesive tape 2 is sent out from the adhesive tape feeding tray 3121 and then bypasses the first tension wheel 3122, the second tension wheel 3123, and the third tension wheel 3124 in sequence. The first tension wheel 3122, the second tension wheel 3123, and the third tension wheel 3124 keep the adhesive tape 2 in tension during transportation.

[0121] As Figures 5 to 7 shown, a take-up reel assembly 36 is further provided on the film feeding frame 31. The take-up reel assembly 36 includes a take-up motor 361, and a take-up reel 362 is provided at the output end of the take-up motor 361. Specifically, before the adhesive tape 2 on the folded film 1 enters the first upper film pulling roller 332 and the first lower film pulling roller 333, the release paper 22 needs to be torn off. The release paper 22 can be wound around the take-up reel 362. The take-up motor 361 drives the take-up reel 362 to rotate, and during the film feeding process, the release paper 22 is torn off and wound up.

[0122] As Figure 5 、 6 、8, 9, and 10 shown, a cutting and sealing assembly 37 is further provided on the film feeding frame 31. The cutting and sealing assembly 37 includes a cutting and sealing frame 371. A heat sealing roller 372 and a heat sealing knife 373 that can move up and down are provided on the cutting and sealing frame 371. The heat sealing roller 372 is located below the heat sealing knife 373. The film pulling assembly 33 transports the folded film 1 that has been bonded to between the heat sealing knife 373 and the heat sealing roller 372. The heat sealing knife 373 moves downward along the third direction Z to cut the folded film 1, and at the same time, it is welded using high temperature, thereby cutting and heat sealing one by one packaging bags with only the bag mouth being open.

[0123] As Figures 8 to 10As shown in the figure, the film pulling assembly 33 is arranged on the sealing and cutting frame 371. The first film pulling driving part 331 is installed on the sealing and cutting frame 371, and the output end of the first film pulling driving part 331 is connected with a first film pulling linkage gear 3741. At both ends of the first lower film pulling roller 333, a second film pulling linkage gear 3742 and a third film pulling linkage gear 3745 are coaxially arranged respectively. A first film pulling belt 3743 is sleeved between the first film pulling linkage gear 3741 and the second film pulling linkage gear 3742. On the side of the heat sealing roller 372 close to the third film pulling linkage gear 3745, a fourth film pulling linkage gear 3746 is coaxially arranged. A second film pulling belt 3747 is sleeved between the third film pulling linkage gear 3745 and the fourth film pulling linkage gear 3746. In this embodiment, the first lower film pulling roller 333 and the heat sealing roller 372 are synchronously linked. The first lower film pulling roller 333 and the heat sealing roller 372 pull and stop synchronously, maintaining the synchronous linkage of film pulling and heat sealing, and ensuring the continuity and stability of bag making. It should be noted that synchronous linkage gears can also be arranged between the first upper film pulling roller 332 and the first lower film pulling roller 333 to achieve further synchronous rotation. Between the heat sealing roller 372 and the first lower film pulling roller 333, an upper heat sealing and pressing film roller 381 and a lower heat sealing and pressing film roller 382 are also arranged. A third film pulling belt 383 is sleeved between the first lower film pulling roller 333 and the lower heat sealing and pressing film roller 382, and the first lower film pulling roller 333 synchronously drives the lower heat sealing and pressing film roller 382 to rotate.

[0124] As Figures 8 to 10 shown, a sealing and cutting driving part 3751 is also installed on the sealing and cutting frame 371. The output end of the sealing and cutting driving part 3751 is connected with a first sealing and cutting linkage gear 3752. At the bottom of the sealing and cutting frame 371, a sealing and cutting linkage shaft 3753 penetrating the sealing and cutting frame 371 is rotatably arranged. A second sealing and cutting linkage gear 3754 is arranged on the sealing and cutting linkage shaft 3753. A first sealing and cutting belt 3755 is sleeved between the second sealing and cutting linkage gear 3754 and the first sealing and cutting linkage gear 3752. Sealing and cutting linkage discs 3756 are arranged at both ends of the sealing and cutting linkage shaft 3753. Sealing and cutting sliders 3757 are respectively arranged on both sides of the sealing and cutting frame 371. On the sealing and cutting sliders 3757, sealing and cutting slide rods 3758 are slidably arranged one by one. The bottoms of the sealing and cutting slide rods 3758 are eccentrically rotatably connected to the sealing and cutting linkage discs 3756 one by one through couplings, and the tops of the sealing and cutting slide rods 3758 are connected to the heat sealing knife 373. Specifically, in this embodiment, the sealing and cutting driving part 3751 drives the sealing and cutting slide rods 3758 to move up and down, thereby driving the heat sealing knife 373 to move up and down for cutting and heat sealing.

[0125] As Figures 8 to 10As shown, at the top of the two cutting and sealing slide rods 3758, there is also a cutting and sealing mounting plate 376 connected. The heat sealing knife 373 is connected below the cutting and sealing mounting plate 376. Below the cutting and sealing mounting plate 376, there is also a water-cooled pressing block 377. Circulating water cooling can be passed through the water-cooled pressing block 377. In the middle of the water-cooled pressing block 377, there is a water-cooling mounting groove 378 that penetrates the water-cooled pressing block 377. The heat sealing knife 373 is located within the water-cooling mounting groove 378. The bottom of the water-cooling mounting groove 378 and the bottom of the heat sealing knife 373 are on the same horizontal line. The water-cooling mounting groove 378 includes a water-cooling upper mounting groove 3781 and a water-cooling lower mounting groove 3782. The water-cooling lower mounting groove 3782 corresponds to the sharp part of the heat sealing knife 373, and the width of the water-cooling lower mounting groove 3782 gradually narrows from top to bottom.

[0126] Specifically, when the heat sealing knife 373 performs cutting and heat sealing, it directly lifts up after cutting and heat sealing. The edges of the position where the folded film 1 is cut and heat sealed will also shrink due to the effect of heat, which will damage the packaging bag. At the same time, when the heat sealing knife 373 lifts up, the packaging bag and the folded film 1 will adhere to the heat sealing knife 373. In this embodiment, the heat sealing knife 373 is located within the water-cooling mounting groove 378. Only the position where the heat sealing knife 373 performs heat sealing and cutting contacts the folded film 1. The edge position of the heat sealing and cutting will be pressed by the bottom surface of the water-cooled pressing block 377. At the same time, cooling and heat insulation are carried out through water cooling. After heat sealing, the heat sealing knife 373 will lift up. Only the position where the heat sealing knife 373 contacts will have a heat seal. Due to the presence of the water-cooled pressing block 377, the folded film 1 will not adhere to the heat sealing knife 373 when the heat sealing knife 373 lifts up, nor will it cause damage to the position next to the cutting position of the folded film 1.

[0127] As Figure 4 and 11 As shown, between the discharge port of the cutting and sealing assembly 37 and the air suction conveying mechanism 4, there are several pressing wheel groups 8 arranged. The pressing wheel groups 8 connect the cutting and sealing assembly 37 and the air suction conveying mechanism 4, enabling the packaging bag to smoothly enter the air suction conveying mechanism 4 and flatten.

[0128] As Figures 12 to 15 As shown, the air suction conveying mechanism 4 includes:

[0129] Suction frame 41, on which a first suction conveyor belt 42 and a second suction conveyor belt 43 extending along the first direction X are provided. Below the top of the first suction conveyor belt 42, a number of first suction slots 411 are provided. Below the top of the second suction conveyor belt 43, a number of second suction slots 412 are provided. A number of suction holes are provided on both the first suction conveyor belt 42 and the second suction conveyor belt 43. The first suction slots 411 and the second suction slots 412 are communicated with each other. Below the first suction slots 411 is a suction box 413, and a suction device such as a suction fan is connected through the suction box 413 to provide suction. The first suction conveyor belt 42 and the second suction conveyor belt 43 are separated from each other by a partition frame 44. The first suction conveyor belt 42 extends from one end of the suction frame 41 to the other end of the suction frame 41, but the second suction conveyor belt 43 only extends from one end of the suction frame 41 to the middle position of the suction frame 41, because a sealing structure will be provided at the latter half position of the suction frame 41, and the sealing structure needs to turn up the flanging 12, so there can be no suction at the latter half position of the second suction conveyor belt 43 on the suction frame 41. The feeding ends of the first suction conveyor belt 42 and the second suction conveyor belt 43 correspond to the discharging end of the film feeding mechanism 3.

[0130] In the embodiment of the present invention, it is divided into a first suction conveyor belt 42 and a second suction conveyor belt 43. The first suction conveyor belt 42 and the second suction conveyor belt 43 respectively correspond to the double-layer bag body 11 and the flanging 12 of the packaging bag, and the first suction conveyor belt 42 and the second suction conveyor belt 43 rotate synchronously, and can be synchronously conveyed before heat-sealing the bag mouth, ensuring the conveying accuracy, and do not affect each other during heat-sealing or edge-sealing, ensuring normal heat-sealing or edge-sealing.

[0131] Such as Figures 12 to 15As shown, one end of the air suction frame 41 is provided with a first air suction driving shaft 421 and a second air suction driving shaft 424. A first air suction driving wheel 4211 is arranged on the first air suction driving shaft 421, and a second air suction driving wheel 4241 is arranged on the second air suction driving shaft 424. The other end of the air suction frame 41 is provided with a first air suction follower shaft 422 and a second air suction follower shaft 423. A first air suction follower wheel 4221 is arranged on the first air suction follower shaft 422, and a second air suction follower wheel 4231 is arranged on the second air suction follower shaft 423. The first air suction conveyor belt 42 is sequentially wound around the first air suction driving wheel 4211, the first air suction follower wheel 4221, the second air suction follower wheel 4231 and the second air suction follower wheel 4231. An air suction driving motor 46 is further arranged on the air suction frame 41, and the output end of the air suction driving motor 46 is connected to the first air suction driving shaft 421. Specifically, a first tensioning roller 425, a second tensioning roller 426 and a third tensioning roller 427 are rotatably arranged on the air suction frame 41. The first tensioning roller 425 is arranged on one side close to the first air suction driving shaft 421, the second tensioning roller 426 is arranged on one side close to the second air suction follower shaft 423, and the third tensioning roller 427 is arranged in the middle of the bottom of the air suction frame 41. A "V" shape is formed among the first tensioning roller 425, the second tensioning roller 426 and the third tensioning roller 427, so that the first air suction conveyor belt 42 is kept tensioned. In the embodiment of the present invention, the first air suction driving shaft 421 is driven to rotate by the air suction driving motor 46, so that the first air suction conveyor belt 42 rotates and conveys on the first air suction driving wheel 4211, the first tensioning roller 425, the third tensioning roller 427, the second tensioning roller 426, the first air suction follower wheel 4221, the second air suction follower wheel 4231 and the second air suction follower wheel 4231. A third air suction follower shaft 431 and a fourth air suction follower shaft 432 are further arranged on the air suction frame 41. A third air suction follower wheel 4311 is arranged on the third air suction follower shaft 431, and a fourth air suction follower wheel 4321 is arranged on the fourth air suction follower shaft 432. A fifth air suction follower wheel 433 is further arranged on the first air suction follower shaft 422, and a sixth air suction follower wheel 434 is further arranged on the second air suction follower shaft 423. The second air suction conveyor belt 43 sequentially bypasses the fifth air suction follower wheel 433, the sixth air suction follower wheel 434, the third air suction follower wheel 4311 and the fourth air suction follower wheel 4321.Specifically, in the embodiment of the present invention, when the first air suction follower shaft 422 rotates, it drives the fifth air suction follower wheel 433 to rotate synchronously. When the second air suction follower shaft 423 rotates, it drives the sixth air suction follower wheel 434 to rotate, thereby driving the second air suction conveyor belt 43 to rotate, so that the first air suction conveyor belt 42 and the second air suction conveyor belt 43 rotate synchronously. The first air suction conveyor belt 42 and the second air suction conveyor belt 43 are driven synchronously by one air suction drive motor 46, effectively ensuring synchronous transportation. When the packaging bag is transported on the first air suction conveyor belt 42 and the second air suction conveyor belt 43, there will be no situations such as deviation or inclination. A first linkage gear 461 is provided at the output end of the air suction drive motor 46, and a second linkage gear 462 is coaxially provided at one end of the first air suction driving shaft 421. A first linkage belt 463 is sleeved between the first linkage gear 461 and the second linkage gear 462. The air suction drive motor 46 drives the first air suction driving shaft 421 to rotate through the first linkage gear 461, the first linkage belt 463 and the second linkage gear 462.

[0132] As Figures 12 to 15As shown, a pressing frame 45 is also provided above the suction frame 41, and a pressing assembly 451 is provided on the pressing frame 45. The connection between the pressing frame 45 and the pressing assembly 451 is an adjustable connection, that is, the position of the pressing assembly 451 can be adjusted by adjusting the pressing frame 45. The pressing assembly 451 includes a pressing conveyor belt 453, and the pressing conveyor belt 453 extends along the first direction X. The pressing conveyor belt 453 is located above the first suction conveyor belt 42. Specifically, in this embodiment, after the packaging bag is completed, the packaging bag containing the article 66 will be transported between the pressing conveyor belt 453 and the first suction conveyor belt 42. The pressing conveyor belt 453 is used to flatten the packaging bag after the packaging is completed, and when the flange 12 is flipped and bonded later, the bonding position remains flat. The press assembly 451 also includes a press mounting frame 4511, one end of which is rotatably provided with a press driving shaft 4512, the other end of which is rotatably provided with a press follower shaft 4513, the press driving shaft 4512 is provided with a press driving wheel 4514, the press follower shaft 4513 is provided with a press follower wheel 4515, and the press conveyor belt 453 is sleeved between the press driving wheel 4514 and the press follower wheel 4515. A press connecting frame 4516 is provided on the side of the press frame 45 close to the second linkage gear 462, and a fifth follower shaft 4517 is rotatably provided on the press connecting frame 4516. A fourth linkage gear 4518 is coaxially provided on the side of the fifth follower shaft 4517 close to the first linkage gear 461. A third linkage gear 4519 is also coaxially provided on the first suction active shaft 421. A second linkage belt 4520 is sleeved between the third linkage gear 4519 and the fourth linkage gear 4518. The fifth follower shaft 4517 passes through the press connecting frame 4516, and a universal coupling (not shown) is provided on the side of the fifth follower shaft 4517 away from the fourth linkage gear 4518, and the universal coupling is connected to the press active shaft 4512. Specifically, in the present embodiment, the suction drive motor 46 drives the first suction active shaft 421 to rotate, and at the same time drives the fourth linkage gear 4518 to rotate through the third linkage gear 4519 and the second linkage belt 4520, and the fourth linkage gear 4518 drives the fifth follower shaft 4517 to rotate, and the fifth follower shaft 4517 drives the pressing active shaft 4512 to rotate through the universal joint, so that the pressing conveyor belt 453 rotates synchronously, and the pressing conveyor belt 453 rotates synchronously with the first suction conveyor belt 42, the upper layer of the double-layer packaging bag is in contact with the pressing conveyor belt 453, and the lower layer of the double-layer packaging bag is in contact with the first suction conveyor belt 42, the pressing conveyor belt 453 and the first suction conveyor belt 42 rotate synchronously, and the upper and lower layers of the double-layer packaging bag keep moving synchronously, and while the packaging bag is flattened, the upper and lower sides of the packaging bag will not be misaligned, wrinkled or damaged.In coordination with the counterclockwise rotation of the first suction conveyor belt 42, in order to make the pressing conveyor belt 453 rotate clockwise, the sixth follower shaft 4522 and the seventh follower shaft 4523 are respectively provided on the upper and lower sides of the fifth follower shaft 4517, the sixth follower shaft 4522 is provided with a fifth linkage gear 4524, the seventh follower shaft 4523 is provided with a sixth linkage gear 4525, and the second linkage belt 4520 passes around the third linkage gear 4519, the sixth linkage gear 4525, the fourth linkage gear 4518 and the sixth linkage gear 4525 in sequence.

[0133] like Figures 12 to 15 As shown, the press mounting frame 4511 includes a first press mounting frame 45111 and a second press mounting frame 45112, the first press mounting frame 45111 and the second press mounting frame 45112 are rotatably connected, the press active shaft 4512 is arranged on the first press mounting frame 45111, the press follower shaft 4513 is arranged on the second press mounting frame 45112, a third press mounting frame 45113 is arranged on the side of the first press mounting frame 45111 close to the second press mounting frame 45112, a press cylinder 4521 is arranged on the third press mounting frame 45113, and the press cylinder 4521 is arranged in an inclined downward manner, and a fourth press mounting frame 45114 is arranged on the second press mounting frame 45112, and the output end of the press cylinder 4521 is connected to the fourth press mounting frame 45114. Specifically, in this embodiment, the pressing cylinder 4521 can control the second pressing mounting frame 45112 to have an up and down swing amplitude. When the finished bag is ready to enter under the pressing conveyor belt 453, the pressing cylinder 4521 is contracted, and the second pressing mounting frame 45112 is in a lifted state. The finished bag can smoothly enter under the pressing conveyor belt 453. After entering, the driving cylinder drives the second pressing mounting frame 45112 to swing down and press, flattening the finished bag and conveying it at the same time, and this cycle repeats. The partition frame 44 includes a partition part 441 and a suction part 442. The suction part 442 is provided with a plurality of suction holes, and the suction holes are communicated with the suction box 413. Specifically, the partition part 441 corresponds to the position during bagging. During bagging, the suction cup is required to suck up the bag opening of the upper layer of the double-layer packaging bag. By setting the suction part 442, the lower layer of the packaging bag is completely sucked up to ensure that the bag opening is opened smoothly without obstruction.

[0134] like Figure 16As shown, the feeding mechanism 5 includes a feeding rack 51, on which a feeding belt 52 is arranged, and a number of pushing rods 53 are arranged at equal intervals on the feeding belt 52. Specifically, in this embodiment, the packaged items 66 are conveyed onto the feeding rack 51 one by one, and the pushing rods 53 on the feeding rack 51 push the items 66 onto the bag opening mechanism 6 one by one. The items 66 can be various, such as cards, books, etc., preferably cards. At the same time, a card issuing machine can be set to convey the items 66 onto the feeding rack 51 one by one.

[0135] As Figure 19 shown, it is a structural schematic diagram of the prior art during bag opening. According to Figure 19 the bag opening method, it can meet all packaging requirements. Before bag opening, the lower layer of the packaging bag is vacuum adsorbed by the packaging bag air suction conveying mechanism, and the upper layer of the packaging bag is adsorbed by the adsorption rod. First, the bag mouth is opened, and then the bag mouth support 62 will be inserted into the bag mouth. The bag mouth support 62 rotates to both sides to open the bag mouth so that the item 66 to be packaged can be smoothly pushed into the packaging bag. Conventional bag mouth supports 62 are all inserted into the bag mouth in a horizontal movement manner. The applicant found that when the bag mouth support 62 is inserted horizontally into the bag mouth, since both the upper and lower layers of the packaging bag need to be adsorbed, and the bag mouth support 62 cannot touch the lower layer of the packaging bag, otherwise the bag mouth support 62 will damage the lower layer of the packaging bag when inserted horizontally. Therefore, a certain length needs to be reserved for both the upper and lower layers of the packaging bag. This requires a longer width for the packaging bag during bag making, and the packaging is not compact enough. To solve the above technical problems, as Figures 20 to 26 shown, in the embodiment of the present invention, the bag opening mechanism 6 includes a bag opening rack 61, a pair of bag mouth supports 62 are arranged on the bag opening rack 61, a blanking channel 621 is arranged on the bag mouth support 62, and the blanking channel 621 facilitates blanking. The bag mouth support 62 is configured to be rotatable, and the rotation of the bag mouth support 62 is to open the bag mouth of the packaging bag; a bag mouth support driving assembly 63 is arranged on the bag opening rack 61, and the bag mouth support driving assembly 63 drives the bag mouth support 62 to move along a preset path 65. The bag mouth support 62 extends along the second direction Y. The bag mouth support driving assembly 63 drives the bag mouth support 62 to be obliquely inserted into the bag mouth of the packaging bag along the preset path 65. The included angle between the preset path 65 and the second direction Y is α, 5°≤α≤15°. Preferably, α is 10°.

[0136] In the embodiment of the present invention, the bag supporting driving component 63 drives the bag supporting nozzle 62 to obliquely insert into the bag opening of the packaging bag along the preset path 65. After being inserted into the packaging bag, the bag supporting nozzle 62 is close enough to the lower layer of the packaging bag but does not contact the lower layer. Without affecting the bag opening, only the upper layer of the packaging bag needs to reserve a length, and the lower layer of the packaging bag does not need to reserve a length, which can shorten the width of the packaging bag, reduce the packaging cost, and at the same time, after packing the item 66, the package is more compact.

[0137] For example, as Figure 25 shown, when the bag supporting nozzle 62 is completely inserted into the bag opening of the packaging bag and then the bag is opened by rotation, both the lower layer and the upper layer of the packaging bag are adsorbed. The bag supporting nozzle 62 is close to the lower layer of the packaging bag, so that the lower layer of the packaging bag does not reserve a length, and only the upper layer of the packaging bag has a reserved length, shortening the width of the packaging bag and reducing the packaging cost. As Figure 26 shown, Figure 26 Figure a is a schematic diagram of the bag supporting nozzle 62 inserted horizontally into the packaging bag to open the bag when packaging the same item 66; Figure 26 Figure b is a schematic diagram of the bag supporting nozzle 62 inserted obliquely into the packaging bag along the preset path 65 of the embodiment of the present invention to open the bag when packaging the same item 66. It can be seen that Figure 26 the width of the packaging bag in Figure b is shorter and the package is more compact. For ordinary items 66, the compactness of the package may not be concerned, but for the packaging of cards, especially for stacked cards, it is required that the cards are aligned and compact. The solution provided by the embodiment of the present invention can well improve the problem of the compactness of packaging cards. In addition, for the currently popular blind box type of cards, the rare card is stacked among several cards and blocked. If the package is not compact, it is easy for players to find loopholes.

[0138] For example, as Figures 21 to 24As shown, the bag opening mechanism 6 of the bagging machine further includes a bag supporting mounting frame assembly 64. The bag supporting nozzle 62 is disposed on the bag supporting mounting frame assembly 64. The output end of the bag supporting driving assembly 63 is connected to the bag supporting mounting frame assembly 64. The bag supporting mounting frame assembly 64 is slidably disposed on the bag opening frame 61. The included angle between the sliding path of the bag supporting mounting frame assembly 64 and the second direction Y is equal to α. Both sides of the bag supporting mounting frame assembly 64 are provided with bag supporting sliders 641. The bag supporting sliders 641 are provided with bag supporting chutes 6411. Both sides of the bag opening frame 61 are provided with bag supporting slide rails 612 that are paired with the bag supporting sliders 641 one by one. The bag supporting slide rails 612 are the sliding paths. The included angle between the bag supporting slide rails 612 and the second direction Y is equal to α. The bag supporting driving assembly 63 is a first bag supporting air cylinder 631. The bag supporting mounting frame assembly 64 further includes two relatively disposed bag supporting driving plates 642. The bag supporting sliders 641 are disposed on the bag supporting driving plates 642 one by one. The output end of the first bag supporting air cylinder 631 is connected to the bag supporting driving plates 642. The bag supporting sliders 641 are disposed on the side of the bag supporting driving plates 642 close to the bag opening frame 61. The output end of the first bag supporting air cylinder 631 is connected to the side of the bag supporting driving plates 642 away from the bag opening frame 61. Specifically, in this embodiment, the two groups of first bag supporting air cylinders 631 synchronously drive the bag supporting driving plates 642 to slide. Since the bag supporting driving plates 642 slide on the slide rails through the bag supporting sliders 641, the entire bag supporting mounting frame assembly 64 slides along the sliding path, and the angle of the sliding path is equal to α. The bag supporting mounting frame assembly 64 then drives the bag supporting nozzle 62 to insert into the bag opening of the packaging bag along the preset path 65.

[0139] As Figures 21 to 24As shown, the bag supporting mounting frame assembly 64 further includes a bag supporting connecting rod 643. The two sides of the bag supporting connecting rod 643 are respectively connected to the two bag supporting driving plates 642. At the bottoms of the two sides of the bag opening frame 61, there are provided bag supporting avoiding grooves 611, and the bag supporting connecting rod 643 passes through the bag supporting avoiding grooves 611. The bag supporting avoiding grooves 611 provide a moving space reserved for the entire bag supporting mounting frame assembly 64. In the middle of the bag supporting connecting rod 643, there are provided two groups of bag supporting fixing frames 644, and the bag supporting nozzles 62 are arranged one-to-one on the bag supporting fixing frames 644. The bag supporting fixing frame 644 includes two first bag supporting fixing plates 6441. The first bag supporting fixing plates 6441 are connected to the bag supporting connecting rod 643, and the tops of the two first bag supporting fixing plates 6441 are connected with a second bag supporting fixing plate 6442. A bag supporting rotating shaft 6443 is rotatably arranged on the second bag supporting fixing plate 6442. A bag supporting bearing is arranged on the second bag supporting fixing plate 6442, and the bag supporting rotating shaft 6443 is sleeved in the bag supporting bearing. The top of the bag supporting rotating shaft 6443 is connected to the bag supporting nozzle 62. At the bottom of the second bag supporting fixing plate 6442, there is also provided a bag supporting rotation driving assembly 645, and the output end of the bag supporting rotation driving assembly 645 is connected to the bottom of the bag supporting rotating shaft 6443. The top of the bag supporting rotating shaft 6443 is connected with a bag supporting connecting plate 6444, and the bag supporting connecting plate 6444 is connected to the bag supporting nozzle 62. The bag supporting rotation driving assembly 645 includes a second bag supporting cylinder 6451. The output end of the second bag supporting cylinder 6451 is provided with a first bag supporting rotating plate 6452. A bag supporting coupling 6453 is arranged on the first bag supporting rotating plate 6452. A second bag supporting rotating plate 6454 is rotatably connected to the bag supporting coupling 6453, and the second bag supporting rotating plate 6454 is connected to the bottom of the bag supporting rotating shaft 6443. In this embodiment, during bag opening, the bag supporting nozzle 62 needs to rotate to open the bag mouth of the packaging bag. The second bag supporting cylinder 6451 drives the first bag supporting rotating plate 6452 to move reciprocally. The first bag supporting rotating plate 6452 will drive the bag supporting coupling 6453 to move reciprocally. Since one end of the second bag supporting rotating plate 6454 is rotatably connected to the bag supporting coupling 6453 and the other end is connected to the bottom of the bag supporting rotating shaft 6443, this will cause the second bag supporting rotating plate 6454 to swing repeatedly with the center point of the bag supporting rotating shaft 6443 as the origin. At the same time, the bag supporting rotating shaft 6443 will also rotate reciprocally. The bag supporting rotating shaft 6443 drives the bag supporting nozzle 62 to drive reciprocally through the bag supporting connecting plate 6444 to continuously open the bag reciprocally.

[0140] As Figure 17 and 18As shown, a bag-opening chute 671 is further provided on the bag-opening rack 61. A bag-opening slide bar 672 is provided on one side of the bag-opening chute 671. A bag-opening slider 679 is slidably arranged on the bag-opening slide bar 672. The bag-opening rack 61 is further provided with a bag-opening driving part (not shown in the figure). The output end of the bag-opening driving part is connected to a bag-opening eccentric disc 674. The bag-opening driving part is a bag-opening driving motor. The output end of the bag-opening driving motor is connected to the bag-opening eccentric disc 674 through a bag-opening belt transmission mechanism. An eccentrically rotating connection rod 673 is eccentrically rotatably connected to the bag-opening eccentric disc 674. The bag-opening connection rod 673 is rotatably connected to the bag-opening slider 679. A bag-opening material pushing shaft 675 is further rotatably arranged on the bag-opening slider 679. A bag-opening material pushing plate 676 is arranged on the bag-opening material pushing shaft 675. The bag-opening material pushing shaft 675 passes through the bag-opening slider 679. A material pushing driving cylinder 677 is further provided on the bag-opening slider 679. The output end of the material pushing driving cylinder 677 is hinged to a material pushing swing arm 678. The material pushing swing arm 678 includes a first material pushing arm 6781 and a second material pushing arm 6782. An included angle is formed between the first material pushing arm 6781 and the second material pushing arm 6782. One end of the material pushing swing arm 678 is connected to the bag-opening material pushing shaft 675. Specifically, after the bag opening is completed, the material pushing driving cylinder 677 drives the bag-opening material pushing shaft 675 to rotate, so that the bag-opening material pushing plate 676 rotates. The bag-opening material pushing plate 676 rotates to the rear side of the item 66 to be packaged. Then, the bag-opening driving part drives the bag-opening eccentric disc 674 to rotate. The bag-opening eccentric disc 674 drives the bag-opening slider 679 to slide along the second direction Y through the bag-opening connection rod 673. The bag-opening slider 679 drives the bag-opening material pushing plate 676 to move along the second direction Y. The bag-opening material pushing plate 676 pushes the item 66 to be packaged into the packaging bag. In such a reciprocating cycle, the items 66 are pushed one by one into the packaging bags on the air suction conveying mechanism 4.

[0141] As Figure 17 and 18 shown, an upper adsorption assembly 68 is further installed on the bag-opening rack 61. The upper adsorption assembly 68 includes an upper adsorption mounting rod 681. An upper adsorption cylinder 682 is installed on the upper adsorption mounting rod 681. The output end of the upper adsorption cylinder 682 is connected to an upper adsorption rod 683. Specifically, when the bag opening of the packaging bag is opened, the bottom of the double-layer bag body 11 is adsorbed by the air suction conveying mechanism 4. The upper layer of the double-layer bag body 11 can be driven by the upper adsorption cylinder 682 to drive the upper adsorption rod 683 to move above the double-layer bag body 11. The upper adsorption rod 683 can be connected to vacuum adsorption, so as to adsorb the top of the double-layer bag body 11, so that the bag opening of the packaging bag is opened, and the bag opening and material pushing are carried out smoothly.

[0142] As Figure 27As shown in the figure, the sealing mechanism 7 includes a sealing mounting frame 71 which is connected to the air suction conveying mechanism 4 and is close to the discharge port of the air suction conveying mechanism 4. A bag guiding plate 72 and a first sealing cylinder 73 are arranged on the sealing mounting frame 71. The output end of the first sealing cylinder 73 is connected with a sealing plate 74, and the sealing plate 74 is located at the rear side of the bag guiding plate 72. A second sealing cylinder 75 is further arranged on the sealing mounting frame 71. The second sealing cylinder 75 is located above the sealing plate 74, and the output end of the second sealing cylinder 75 is connected with a mouth pressing plate 76. After the article 66 is bagged, the packaging bag continues to be conveyed along the air suction conveying mechanism 4. When passing through the bag guiding plate 72, the flange 12 of the packaging bag will be turned up along the bag guiding plate 72. Since the rear side of the bag guiding plate 72 is the sealing plate 74, the first sealing cylinder 73 will drive the sealing plate 74 to move along the second direction Y, so as to turn the flange 12 above the upper layer of the double-layer bag body 11. At this time, the adhesive strip 21 bonds the double-layer bag body 11 and the flange 12, so that the bag mouth of the packaging bag is sealed. Finally, the second sealing cylinder 75 drives the mouth pressing plate 76 along the third direction Z, so that the adhesive strip 21 is bonded more firmly.

[0143] As Figure 28 and 29 shown, as an alternative scenario, after the sealing mechanism completes the sealing, the bag mouth of the packaging bag is not completely sealed. For some products packaged in packaging bags, it is required that the bag mouth is completely sealed. To adapt to this scenario, in the embodiment of the present invention, a heat sealing mechanism can be optionally provided, including: a first heat sealing fixing plate 911 which is connected to the air suction conveying mechanism of the packaging machine; a second heat sealing fixing plate 912 which is connected to the first heat sealing fixing plate 911, and heat sealing movable rods 92 are movably sleeved on both sides thereof; a third heat sealing fixing plate 913 which is connected to the first heat sealing fixing plate 911, is located below the second heat sealing fixing plate 912, and the heat sealing movable rods 92 are movably sleeved on both sides thereof; a fourth heat sealing fixing plate 914 which is connected to the top of the heat sealing movable rods 92, and a first heat sealing cutter 93 is arranged below the fourth heat sealing fixing plate 914; a fifth heat sealing fixing plate 915 which is located below the fourth heat sealing fixing plate 914 and above the first heat sealing fixing plate 911, and a second heat sealing cutter 94 is arranged thereon. The second heat sealing cutter 94 is located below the first heat sealing cutter 93, and the heat sealing movable rods 92 are movably sleeved on the fifth heat sealing fixing plate 915; a sixth heat sealing fixing plate 916 which is located below the third heat sealing fixing plate 913, and both ends thereof are connected to the bottom of the heat sealing movable rods 92; a heat sealing driving mechanism 95 which is a cylinder and is arranged on the third heat sealing fixing plate 913, and the output end thereof is connected to the sixth heat sealing fixing plate 916; a heat sealing linkage assembly 96 which connects the sixth heat sealing fixing plate 916 and the fifth heat sealing fixing plate 915.

[0144] In the embodiment of the present invention, both the first heat-sealing knife 93 and the second heat-sealing knife 94 are heated. The seventh heat-sealing fixed plate 917 is driven to move up and down by the heat-sealing driving mechanism 95. The seventh heat-sealing fixed plate 917 drives the fourth heat-sealing fixed plate 914 to move up and down through the heat-sealing movable rod 92, so that the first heat-sealing knife 93 can move up and down. At the same time, the fifth heat-sealing fixed plate 915 is driven to move up and down through the heat-sealing linkage assembly 96, so that the second heat-sealing knife moves up and down. The first heat-sealing knife and the second heat-sealing knife approach or move away from each other to perform heat-sealing on the bag mouth of the packaging bag, so that the bag mouth of the packaging bag is completely sealed, improving the heat-sealing efficiency and not damaging the packaging bag at the same time.

[0145] As Figure 28 and 29 shown, a seventh heat-sealing fixed plate 917 is further provided between the second heat-sealing fixed plate 912 and the third heat-sealing fixed plate 913; a heat-sealing linkage shaft 961 is rotatably provided between the first heat-sealing fixed plate 911 and the seventh heat-sealing fixed plate 917; the heat-sealing linkage assembly 96 includes a heat-sealing swing arm 962. The middle part of the heat-sealing swing arm 962 is sleeved on the heat-sealing linkage shaft 961. One end of the heat-sealing swing arm 962 is hinged with a first heat-sealing linkage rod 963. The bottom of the first heat-sealing linkage plate is hinged with the sixth heat-sealing fixed plate 916. The other end of the heat-sealing swing arm 962 is hinged with a second heat-sealing linkage rod 964. The top of the second heat-sealing linkage rod 964 is hinged with the fifth heat-sealing fixed plate 915.

[0146] A first heat-sealing avoidance groove is provided on the third heat-sealing fixed plate 913, and the first heat-sealing linkage rod 963 passes through the first heat-sealing avoidance groove. A second heat-sealing avoidance groove is provided on the second heat-sealing fixed plate 912, and the second heat-sealing linkage rod 964 passes through the second heat-sealing avoidance groove.

[0147] In the embodiment of the present invention, when the heat-sealing driving mechanism 95 drives the sixth heat-sealing fixed plate 916 to move downward, the sixth heat-sealing fixed plate 916 drives the fourth heat-sealing fixed plate 914 to move downward through the heat-sealing movable rod 92. The fourth heat-sealing fixed plate 914 drives the first heat-sealing knife 93 to move downward. At the same time, the sixth heat-sealing fixed plate 916 will drive the first heat-sealing linkage rod 963 to move downward. The first heat-sealing linkage rod 963 will drive the heat-sealing swing arm 962 to swing. The heat-sealing swing arm 962 will drive the second heat-sealing linkage rod 964 to move upward. The second heat-sealing linkage rod 964 drives the fifth heat-sealing fixed plate 915 to move upward, and the second heat-sealing knife moves upward simultaneously. The first heat-sealing knife 93 and the second heat-sealing knife 94 approach each other to perform heat-sealing on the bag mouth of the packaging bag. Through the heat-sealing linkage assembly 96, a single heat-sealing driving mechanism 95 can drive the first heat-sealing knife 93 and the second heat-sealing knife 94 to approach each other for heat-sealing at the same time, ensuring heat-sealing synchronism.

[0148] As Figure 28 and 29 shown, an eighth heat-sealing fixing plate 918 is further connected below the fourth heat-sealing fixing plate 914. The first heat-sealing cutter 93 is disposed on the eighth heat-sealing fixing plate 918. A buffer limiting rod 97 is connected below the eighth heat-sealing fixing plate 918. Above the fifth heat-sealing fixing plate 915, a ninth heat-sealing fixing plate 919 is further provided. The second heat-sealing cutter is disposed on the ninth heat-sealing fixing plate 919. The buffer limiting rod 97 can abut against the ninth heat-sealing fixing plate 919. Specifically, in this embodiment, by providing the buffer limiting rod 97, when the first heat-sealing cutter and the second heat-sealing cutter approach each other, the buffer limiting rod 97 is provided to balance the force between the first heat-sealing cutter and the second heat-sealing cutter during heat-sealing, and the service life of the first heat-sealing cutter and the second heat-sealing cutter can be extended.

[0149] As Figure 29 shown, an air suction and material collecting assembly 98 is further provided on the fifth heat-sealing fixing plate 915. The air suction and material collecting assembly 98 includes an air suction and material collecting fixing frame 981. An air suction and material collecting shovel 982 is disposed on the air suction and material collecting fixing frame 981. A material collecting inlet 9821 and a material collecting outlet 9822 are provided on the air suction and material collecting shovel 982. The material collecting port is located at the rear side of the first heat-sealing cutter 93 and the second heat-sealing cutter 94. The material collecting outlet 9822 can be connected to a negative pressure device. Specifically, in this embodiment, when the first heat-sealing cutter 93 and the second heat-sealing cutter 94 perform heat-sealing, the excess bag mouth material head will be cut off. The bag mouth material head will be sucked in from the material collecting inlet 9821 by negative pressure.

The bag mouth support 62 is inserted into the bag mouth of the packaging bag along the preset path 65 and then rotates to open the bag;

[0154] Push the item 66 to be packaged into the packaging bag. Specifically, the bag-opening and material-pushing plate pushes the item 66 to be packaged into the packaging bag that has already completed bag-opening, and then the bag-opening mechanism 6 resets to open the next packaging bag;

[0155] Seal the opening of the packaging bag. Specifically, the packaging bag that has already completed the bagging of the item 66 continues to be conveyed by the air-suction conveying mechanism 4 to the sealing mechanism 7 for sealing.
