For example, the patent with the publication number CN107934071A discloses a red packet card packaging machine, which includes a frame, an operation panel, a characteristic testing mechanism and an electrical box arranged on the frame. The operation panel and the electrical box are both connected to the characteristic testing mechanism; the characteristic testing mechanism includes a card issuing mechanism for mixed loading. The card issuing mechanism transports the mixed cards to the bag-making mechanism for packaging through a card conveying mechanism. After the packaged cards pass through the longitudinal sealing and conveying mechanism and the transverse sealing mechanism to seal the packaging bag in sequence, the cards are output through an output mechanism.

[0016] A packaging method of a packaging machine comprises the following steps:

[0017] S1. Automatic feeding and positioning: Stack the fragrance cards in the card storage bin. After sorting by vibrating feeding, the side baffles of the automatic card sending component automatically adjust the distance based on the size of the fragrance cards, and cooperate with the rotation of the card separating wheel to separate single fragrance cards, and then guide and convey them to the packaging station through the card storage box;

[0018] S2. Synchronous conveying and monitoring: The conveyor belt of the fragrance card conveying mechanism receives the fragrance cards and is driven by a synchronous wheel drive component to convey at a constant speed. During this period, the photoelectric sensor monitors the position and posture of the fragrance cards in real time;

[0019] S3. Double-sided quantitative fragrance dropping: When the fragrance cards are conveyed by the conveyor belt, the upper fragrance dropping component drives the metering pump through a PID controller, extracts a quantitative amount of fragrance from the fragrance storage tank, and evenly sprays it onto the upward-facing side of the fragrance cards through an atomizing nozzle; when the photoelectric eye detector recognizes that the fragrance cards reach below the fragrance card flipping component, the lifting cylinder drives the flipping clamping plate to descend, and the material taking suction cup adsorbs the fragrance cards and flips them 180°, and then accurately drops the fragrance cards back onto the conveyor belt; repeat the fragrance dropping step to complete double-sided permeation fragrance dropping;

[0020] S4. Dynamic bag making: The fragrance card bag making mechanism adjusts the film roll tension according to the size of the fragrance cards, and forms a three-side open packaging bag from the film roll through the bag making and forming component, and the fragrance card conveying mechanism pushes the fragrance cards into the bag;

[0021] S5. Longitudinal pre-sealing and positioning: The longitudinal sealing mechanism of the fragrance card packaging tightens the two sides of the packaging bag through the film pulling component, and completes the side pre-sealing through the longitudinal sealing component to form a continuous bag body, and conveys it to the next process;

[0022] S6. Vacuum Exhaust Sealing: Before the end sealing of the packaging bag, the scented card enters the vacuum chamber. The push plate descends under the drive of the transverse sealing and cutting mechanism of the scented card, and discharges the excess air in the scented card packaging bag. At the same time, the vacuum pump starts to extract the air in the vacuum chamber to form a vacuum environment. When the vacuum degree reaches the set value, the packaging machine performs end sealing and cutting in a vacuum state.

[0023] S7. Intelligent Transverse Sealing and Cutting: The transverse heat-sealing component descends along the lifting guide component to complete the heat-sealing of the packaging bag, and at the same time, the cutting component completes the cutting between the ends of two adjacent packaging bags. Among them, the intelligent temperature control system (not shown in the figure) uses temperature sensors to collect temperature data of the packaging area in real time and transmits it to the control module. The control module compares the real-time temperature with the preset optimal temperature range. If the temperature is lower than the lower limit, the control module starts the heating element to raise the temperature of the packaging area; if the temperature is higher than the upper limit, the control module starts the refrigeration element to lower the temperature of the packaging area.

[0024] S8. Quality Inspection and Outfeeding: After the scented card is vacuum-packed, the sealing integrity is verified by a vision detector, and the qualified products are sorted by the outfeeding mechanism and packed into boxes to complete the packaging process.

[0025] In summary, the beneficial effects of the present invention are as follows:

[0026] For products such as scented cards with high volatility, the present invention solves the problems of low efficiency and easy errors in manual feeding by setting an automatic feeding mechanism on the pillow-type packaging machine, improving the overall efficiency of the packaging production line. By setting an essence dropping component at the packaging station corresponding to the scented card conveying mechanism, it can continuously supplement essence for the scented card during the packaging process to prevent the loss of fragrance during transportation. At the same time, by setting a scented card flipping component, the scented card can evenly penetrate the essence on both sides, further enhancing the fragrance effect of the scented card and prolonging its fragrance retention time, thereby improving the user experience of the product.

[0045] The following Figure 1-12 further describes in detail the embodiments of a perfume card pillow packaging machine and its packaging method of the present invention in conjunction with the attached

[0046] A perfume card pillow packaging machine, as Figures 1 to 3 shown, includes a frame 1, a perfume card feeding mechanism 2, a perfume card conveying mechanism 3, a perfume card bag-making mechanism 4, a perfume card packaging longitudinal sealing mechanism 5, and a perfume card transverse sealing and cutting mechanism 6 that are sequentially arranged on the frame 1 along the processing direction. There are multiple groups of perfume card feeding mechanisms 2, and the multiple groups of perfume card feeding mechanisms 2 are equidistantly arranged on one side of the perfume card conveying mechanism 3, and the end of the perfume card feeding mechanism 2 is connected to the perfume card conveying mechanism 3; there are multiple packaging stations 322 on the perfume card conveying mechanism 3, and above the packaging station 322, there is an essence dropping component 7 for adding essence; the perfume card bag-making mechanism 4 is installed in the frame 1, and a bag-making and forming component 9 is arranged between the end of the perfume card conveying mechanism 3 and the perfume card packaging longitudinal sealing mechanism 5, and the bag-making and forming component 9 is cooperatively connected with the perfume card bag-making mechanism 4.

[0047] Specifically, for products with fragrance or volatile odors such as scented cards, ordinary packaging machines expose such products to the air for a long time during packaging, which easily causes part of the fragrance to be lost after packaging, resulting in the fragrance not lasting. At the same time, existing packaging machines need to use manual feeding and card issuance, resulting in low work efficiency; however, the present invention provides an automatic feeding mechanism on the pillow packaging machine to completely solve the problems of low efficiency and easy errors in manual feeding, thereby improving the overall efficiency of the packaging production line; and by providing a flavor dripping component 7 at the packaging station 322 corresponding to the scented card on the conveying mechanism, it can continuously replenish the scented card with flavor during the packaging process to prevent the problem of fragrance loss during the conveying process, making the fragrance card more intense and lasting, and improving the user experience of the product; in addition, the exhaust mechanism is used to place the scented card in a vacuum sealed environment during packaging and sealing, which not only effectively reduces the contact between the scented card and the air and prevents the fragrance from being lost, but also significantly prolongs the fragrance retention time of the scented card.

[0048] In this embodiment, if Figure 4 and 7 As shown, the scent card feeding mechanism 2 includes a workbench 21, a card storage bin 22 fixed on the workbench 21, and a discharging track 23 connected to the top of the card storage bin 22 and arranged obliquely. A vibration driver 221 is arranged at the bottom of the card storage bin 22, and a feeding track 222 is arranged along the internal spiral of the card storage bin 22; one end of the discharging track 23 is connected to the end of the feeding track 222; and the other end is connected to an automatic card issuing assembly 24. The automatic card issuing assembly 24 includes a card holder 241, a card storage box 242 for stacking the scent cards to be issued, and a card shifting wheel 243 arranged at the bottom of the box for shifting a single scent card for unloading. The card holder 241 is fixed on the workbench 21, and the card holder 241 has a plurality of pulley transmission assemblies 244 for conveying the unloaded scent cards; the card storage box 242 consists of a fixed frame 2421, an intermediate baffle 2422 sleeved on the fixed frame 2421, and a position The middle baffle 2422 is composed of side baffles 2423 on both sides, and the fixing frame 2421 is tilted on the card seat 241; the middle baffle 2422 and the side baffles 2423 are movably connected to the fixing frame 2421, and the bottom end of the middle baffle 2422 is bent into an arc shape; the card shifting wheel 243 is located on the back side of the middle baffle 2422, and the card shifting wheel 243 is sleeved on the card shifting shaft, and the two sides of the card shifting shaft are linked to the pulley transmission assembly 244.

[0049] Specifically, the process of automatic feeding of scent cards is as follows: a large number of scent cards are poured into the card storage bin 22, and the vibration driver 221 at the bottom of the card storage bin 22 is activated. The vibration generated by the vibration driver 221 causes the scent cards to gradually move upward along the spiral feeding track 222 in the card storage bin 22. During the movement, the scent cards are automatically arranged to avoid stacking or jamming. The scent cards enter the discharge track 23 in turn. The inclined design of the discharge track 23 allows the scent cards to slide toward the automatic card issuing assembly 24 by their own gravity. When the scent cards reach the card storage box 242 of the automatic card issuing assembly 24, since the bottom end of the middle baffle 2422 of the card storage box 242 is bent into an arc, and the middle baffle 2422 and the side baffle 2423 are movably connected to the fixing frame 2421, the scent cards will automatically adjust their position to adapt to the structure of the card storage box 242. According to the size and thickness of the scent cards, the operator can fine-tune the spacing between the side baffles 2423 again to ensure that the scent cards can be smoothly stacked and stored in the card storage box 242. Then the card-pick-up shaft starts to rotate under the linkage of the pulley transmission assembly 244, driving the card-pick-up wheel 243 mounted thereon to rotate. The paddles on the card-pick-up wheel 243 pick out the stacked scent cards one by one from the card storage box 242, and the picked scent cards are accurately transported to the packaging station 322 of the conveyor belt 32 of the scent card conveying mechanism 3 through the pulley transmission assembly 244 in the card seat 241, thereby realizing the automatic and sequential loading of the scent cards, greatly improving the loading efficiency and accuracy.

[0050] In this embodiment, if Figure 5 , 6 As shown, the aroma card conveying mechanism 3 includes a conveying frame 31, a conveyor belt 32 and a synchronous wheel driving assembly 33. The conveying frame 31 is horizontally arranged on one side of the feeding end of the frame 1, and baffle plates 311 are arranged on both sides of the conveying frame 31. A photoelectric sensor for detecting aroma cards is arranged at a position corresponding to the automatic card issuing assembly 24 on the baffle plate 311, and the photoelectric sensor is connected to the synchronous wheel driving assembly 33 by signal; the conveyor belt 32 is installed in the conveying frame 31, and limit strips 321 are arranged on the conveyor belt 32 at equal intervals, and a packaging station 322 for limiting the position of the aroma card is formed between two adjacent limit strips 321; the synchronous wheel driving assembly 33 is built in the conveying frame 31, and the synchronous wheel driving assembly 33 is connected to the conveyor belt 32 by transmission.

[0051] Specifically, after the conveyor belt 32 of the scent card conveying mechanism 3 receives the scent card from the automatic card issuing assembly 24, the photoelectric sensor at the position of the corresponding card issuing assembly on the material blocking plate 311 starts to work; the photoelectric sensor continuously emits and receives light, and when the scent card passes through the detection area, it will block the light, causing the electrical signal output by the photoelectric sensor to change. The signal is transmitted to the synchronous wheel drive assembly 33, and the synchronous wheel drive assembly 33 accurately controls the rotation speed and conveying distance of the conveyor belt 32 according to the received signal, ensuring that the scent card can be accurately positioned on the packaging station 322 and conveyed forward at a stable speed. In addition, during the conveying process, the material blocking plates 311 on both sides of the conveyor belt 32 play a role in limiting the position of the scent card to prevent the scent card from being offset due to the vibration of the conveyor belt 32 or other external forces. At the same time, in order to prevent the baffle plate 311 from affecting the operation of the aroma card turning assembly 11, the baffle plate 311 is provided with an avoidance groove, and the aroma card turning assembly 11 is installed in the avoidance groove; the packaging station 322 formed between two adjacent limit strips 321 further ensures that the position of the aroma card is fixed, which is convenient for subsequent essence dripping and packaging operations.

[0052] It is worth mentioning that when the incense card passes through the detection area, if the position of the incense card is offset or damaged, the electrical signal output by the photoelectric sensor 34 changes, and the signal is transmitted to the synchronous wheel drive component 33 to suspend its operation, and trigger the alarm device to remind the operator; the operator adjusts or replaces the incense card according to the alarm prompt, and then presses the reset button, and the incense card conveying mechanism 3 continues to operate.

[0053] In this embodiment, if Figure 7 As shown, the flavor dripping assembly 7 includes a support frame 71 fixed to the top of the aroma card conveying mechanism 3, a flavor storage tank 72, an atomizing nozzle 73 and a metering pump 74. A plurality of flavor storage tanks 72 and atomizing nozzles 73 are provided, and the plurality of flavor storage tanks 72 and atomizing nozzles 73 are fixed on the support frame 71 at equal distances and correspond to the packaging station 322; the flavor storage tank 72 and the atomizing nozzle 73 are connected through a pipeline 75, and the atomizing nozzle 73 is built with a PID controller; the metering pump 74 is provided on the pipeline 75, and the metering pump 74 is electrically connected to the PID controller; the atomization amount is adjusted according to the signal feedback of the PID controller; when the aroma card arrives at the packaging station 322 along the conveyor belt 32 and starts to be conveyed, the flavor dripping assembly 7 located above the aroma card conveying mechanism 3 starts to work. The PID controller sends a control signal to the metering pump 74 according to the preset flavor spraying dosage. After the metering pump 74 is started, a fixed amount of flavor is drawn from the flavor storage tank 72 and transported to the atomizing nozzle 73 through the pipeline 75 .

[0054] Among them, the PID controller built into the atomizing nozzle 73 monitors the working state of the nozzle in real time. According to parameters such as the flow rate and pressure of the essence in the pipeline 75, it automatically adjusts the atomizing effect of the nozzle to ensure that the essence can be evenly sprayed on the surface of the scent card. During the spraying process, the operator can observe the spraying situation of the essence through the observation window. If problems such as uneven spraying or nozzle blockage are found, the equipment can be paused in time to clean or maintain the atomizing nozzle 73. At the same time, the operator can also fine-tune the parameters of the PID controller through the relevant buttons on the control panel 101 according to the actual production situation to optimize the spraying effect of the essence.

[0055] In this embodiment, as Figure 4 and Figure 8 shown, the scent card flipping assembly 11 includes a lifting bracket 111, a flipping clamping plate 112 arranged on the lifting bracket 111, and a rotating motor 113 for driving the flipping clamping plate 112 to rotate. The lifting bracket 111 is composed of multiple parallel lifting rods. A lifting sleeve 114 is slidably connected to the lifting rod, and one end of the lifting sleeve 114 is drivingly connected to a lifting cylinder 115; the rotating motor 113 is fixedly connected to the lifting sleeve 114, and the output shaft end of the rotating motor 113 is drivingly connected to an L-shaped fixing plate. An electric eye detector 116 for detecting the scent card is arranged on the L-shaped fixing plate; a telescopic electric cylinder 118 is connected between the flipping clamping plates 112. The telescopic electric cylinder 118 is fixedly connected to the L-shaped fixing plate, and the output shaft end of the telescopic electric cylinder 118 is drivingly connected to the flipping clamping plate 112.

[0056] Specifically, in order to further improve the fragrance retention time of the scent card, the scent card needs to be double-sided sprayed with essence. The scent card flipping assembly 11 can flip the scent card after single-sided dropping of the essence. Specifically, when the scent card is conveyed by the conveyor belt 32 to the position below the scent card flipping assembly 11, after the electric eye detector 116 detects the scent card signal, the lifting cylinder 115 drives and controls the lifting sleeve 114 to descend, and controls and adjusts the distance between the flipping clamping plates 112 through the telescopic electric cylinder 118 so that the flipping clamping plates 112 can adjust the clamping force according to the size of the scent card; at the same time, in order to further improve the grasping accuracy of the flipping clamping plates 112, a picking suction cup 117 can be arranged on the flipping clamping plates 112 to cooperate with the scent card, which can also avoid damaging the scent card, and the flipping clamping plates 112 are controlled to flip by the rotating motor 113. When the scent card is flipped 180° (that is, the original bottom surface of the scent card attached to the conveyor belt 32 is flipped upwards, and the top surface with the dropped essence is flipped downwards), the flipping clamping plates 112 are controlled to release the scent card by the telescopic electric cylinder 118, so that the scent card falls back into the packaging station 322 on the conveyor belt 32 and is conveyed again. At this time, the scent card completes double-sided dropping of the essence, further improving the uniformity of the essence dropping and effectively extending its fragrance retention time.

[0057] It should be noted that since the card flipping assembly 11 is installed on one side of the conveyor belt 32, when the flipping clamp plate 112 descends to clamp the card, its descending stroke will be affected by the baffle plate 311. Therefore, the lower end of the lifting bracket 111 is installed in the avoidance groove opened on the baffle plate 311, so that the maximum descending stroke of the flipping clamp plate 112 is at the same height as the conveyor belt 32. At this time, the flipping clamp plate 112 fits the surface of the conveyor belt 32, and the picking suction cup 117 is used to accurately clamp the card. In addition, the diameter of the picking suction cup 117 on the flipping clamp plate 112 determines the thickness of the item it clamps. Therefore, the thickness of the card clamped by the card flipping assembly in this application should be greater than 20 mm, and the optimal range is between 20 - 50 mm.

[0058] In this embodiment, as Figure 9 , 10 shown, the card bag-making mechanism 4 is installed in the frame 1, and a bag-making and forming assembly 9 is arranged between the end of the card conveying mechanism 3 and the card packaging longitudinal sealing mechanism 5. The bag-making and forming assembly 9 is cooperatively connected with the card bag-making mechanism 4; the bag-making and forming assembly 9 includes a forming support plate 91, a former 92, and a feeding support plate 93. The forming support plate 91 is fixed to the bottom end of the feeding support plate 93; the feeding support plate 93 is arranged at the same height as the conveyor belt 32; the former 92 is connected between the feeding support plate 93 and the conveyor belt 32, and the former 92 is clamped on the forming support plate 91.

[0059] Among them, the card bag-making mechanism 4 includes a unwind roller group 41, a support roller group 42, and an adjusting roller group 43. An adjusting handle 411 is arranged on one side of the unwind roller group 41, and both ends of the unwind roller group 41 are rotatably connected in the frame 1; the support roller group 42 is arranged between the unwind roller group 41 and the winding roller group, and a clamping seasoning rod 421 is arranged inside the support roller group 42; both ends of the adjusting roller group 43 are movably connected with an adjusting bracket 431, and the adjusting bracket 431 is fixedly connected to the feeding support plate 93.

[0060] Specifically, the working process of packaging film bagging is as follows: the packaging film roll is gradually released by rotating the unwinding roller group 41, and the packaging film enters the bag-making and forming assembly 9 after being guided and tension-adjusted by the supporting roller group 42 and the adjusting roller group 43; the former 92 of the bag-making and forming assembly 9 gradually bends the packaging film into the shape of a packaging bag under the support of the forming support plate 91; wherein, the feed support plate 93 is set at the same height as the conveyor belt 32, so that the fragrant card can smoothly enter the formed packaging bag from the conveyor belt 32. During the bag-making process, the operator can adjust the speed of the unwinding roller group 41 and the position of the adjusting roller group 43 according to the size and thickness of the fragrant card through the control button on the control panel 101 to control the conveying speed and tension of the packaging film, thereby ensuring that the forming size of the packaging bag meets the requirements. At the same time, the operator also needs to pay close attention to the quality of the packaging film, such as whether there is damage, wrinkles, etc., and replace the packaging film roll in time if any problems are found.

[0061] In this embodiment, if Figure 11 As shown, the longitudinal sealing mechanism 5 for the fragrance card packaging includes a film-pulling assembly 51 for pulling the two sides of the packaging film together, a longitudinal sealing assembly 52 for longitudinally sealing the packaging film, and a lifting drive assembly 53 for driving the film-pulling assembly 51 and the longitudinal sealing assembly 52. ​​The film-pulling assembly 51 and the longitudinal sealing assembly 52 are provided in multiple groups, and the multiple groups of film-pulling assemblies 51 and the longitudinal sealing assemblies 52 are slidably connected to the lifting drive assembly 53.

[0062] Specifically, the lifting drive assembly 53 includes a mounting bracket 531, a lifting guide rail 532 and a lifting drive cylinder 533; one side of the mounting bracket 531 is fixedly connected to the lifting guide rail 532, and a sliding plate 534 is slidably connected to the lifting guide rail 532, and the film drawing assembly 51 and the longitudinal sealing assembly 52 are fixed on the sliding plate 534; the lifting drive cylinder 533 is transmission-connected with the sliding plate 534 to drive the film drawing assembly 51 and the longitudinal sealing assembly 52 to rise and fall synchronously; the film drawing assembly 51 includes a movable film drawing wheel 511, a fixed film drawing wheel 512 and a bearing seat 513, the movable film drawing wheel 511 and the fixed film drawing wheel 512 are arranged in parallel, and the movable film drawing wheel 511 The top end of the fixed film-drawing wheel 512 is connected to the lifting drive assembly 53 through a bearing seat 513, and the movable film-drawing wheel 511 and the bearing seat at the top end of the fixed film-drawing wheel 512 are movably connected through an adjusting shaft 514, so that the distance between the movable film-drawing wheel 511 and the fixed film-drawing wheel 512 is adjustable; when the packaging bag loaded with fragrance cards is side-sealed, the film-drawing assembly 51 and the longitudinal sealing assembly 52 are driven down by starting the lifting drive assembly 53, and the movable film-drawing wheel 511 and the fixed film-drawing wheel 512 fit the two sides of the packaging bag, and the two sides of the packaging bag are tightened and fit together through the adjusting shaft 514 to ensure that the packaging film tightly wraps the fragrance cards.

[0063] Among them, the longitudinal sealing assembly 52 and the film pulling assembly 51 have the same structure. The only difference is that a heating element is provided inside the longitudinal sealing assembly 52. After the two sides of the packaging bag are tightened, the heating element pre-heats the longitudinal sealing assembly to an appropriate temperature, and then seals the side edges of the packaging bag to be tightened through the rolling action, thereby completing the longitudinal sealing packaging of the packaging bag. In addition, the staff can adjust the heating temperature of the longitudinal sealing assembly 52 through the temperature adjustment button on the control panel 101 to meet the sealing requirements of different material packaging films.

[0064] In this embodiment, an exhaust assembly 8 for evacuating the air inside the packaging bag is provided on the perfume card horizontal sealing and cutting mechanism 6; the exhaust assembly 8 includes a vacuum chamber 81, a vacuum pump 82, and a push plate 83. The vacuum chamber 81 is surrounded by a plurality of spliced card plates, and the vacuum chamber 81 is sleeved on the perfume card horizontal sealing and cutting mechanism 6; the vacuum pump 82 is fixedly connected to the outside of the vacuum chamber 81, and the vacuum pump 82 is connected to the vacuum chamber 81 through a suction pipe; the push plate 83 is arranged inside the vacuum chamber 81, and there are a plurality of push plates 83. The plurality of push plates 83 are respectively arranged on both sides and the top of the gear conveyor belt, and one end of the push plate 83 is connected to the perfume card horizontal sealing and cutting mechanism 6, and the other end is provided with a sponge soft pad 831.

[0065] Specifically, when the perfume card enters the vacuum chamber 81 along with the conveyor belt 32 after completing the longitudinal sealing, the perfume card horizontal sealing and cutting mechanism 6 drives the push plate 83 to descend. During the descent of the push plate 83, the excess air inside the perfume card packaging bag is squeezed out through the sponge soft pad 831; after the push plate 83 finishes squeezing, the vacuum pump 82 is started to pump out the air inside the vacuum chamber 81 to form a vacuum environment. Among them, slots for inputting or outputting the packaging bag are separately provided on both sides of the vacuum chamber 81; at the same time, the operator can view the vacuum degree value inside the vacuum chamber 81 in real time through the vacuum degree display screen on the control panel 101; when the vacuum degree reaches the preset value, the packaging machine completes the packaging and sealing in a vacuum state. Then, the perfume card horizontal sealing and cutting mechanism 6 is used to seal and cut the port of the packaging bag; this not only avoids the problem of fragrance loss caused by the contact between the perfume card and the air inside the packaging bag, but also significantly extends the fragrance retention time of the perfume card.

[0066] In this embodiment, as Figure 12 shown, the perfume card horizontal sealing and cutting mechanism 6 includes a lifting and guiding assembly 61, a horizontal heat sealing assembly 62, and a cutting knife assembly 63. The lifting and guiding assembly 61 is used to drive the horizontal heat sealing assembly 62 and the cutting knife assembly 63 to lift up and down, and the lifting and guiding assembly 61 is axially arranged on the frame 1. The horizontal heat sealing assembly 62 and the cutting knife assembly 63 are connected to the lifting and guiding assembly 61, and the horizontal heat sealing assembly 62 is cooperatively connected with the cutting knife assembly 63.

[0067] Specifically, the lifting and guiding assembly 61 includes positioning guide columns 611, guide sleeves 612 and a guide plate 613. There are at least two positioning guide columns 611, and the positioning guide columns 611 are arranged in parallel on the frame 1; the guide sleeves 612 are slidably connected to the positioning guide columns 611, and the guide plate 613 is horizontally connected between and fixed to the two guide sleeves 612, and a driving member is drivingly connected to one side of the guide plate 613; the horizontal heat-sealing assembly 62 includes a heat-insulating plate 621, a heating plate 622 and a sealing plate 623 arranged in sequence from top to bottom. One end of the heat-insulating plate 621 is fixedly connected to the guide plate, and the other end is connected to the heating plate 622; the heating plate 622 is internally provided with heating rods, and the heating rods are externally connected to a power supply; a groove is formed at the middle position of the bottom end of the sealing plate 623; the cutting knife assembly 63 is composed of a horizontal cutting knife 631, a connecting rod 632 and an elastic connecting member 633. The horizontal cutting knife 631 is installed in the groove, and both sides of the horizontal cutting knife 631 are fixedly connected to the connecting rod 632. One end of the connecting rod 632 passes through the guide plate 613 and is movably connected to the elastic connecting member 633, and the elastic connecting member 633 is connected to the guide plate 613.

[0068] Among them, the process of transverse sealing and cutting of the end of the packaging bag is as follows: First, the heating plate 622 pre-heats the sealing plate 623 to a preset temperature. As the packaging bag is conveyed to the lower part of the fragrance card transverse sealing and cutting mechanism 6, the lifting and guiding assembly 61 drives the horizontal heat-sealing assembly 62 and the cutting knife assembly 63 to descend until the sealing plate 623 abuts against the packaging bag and performs hot pressing and sealing on it. Then, as the lifting and guiding assembly 61 continues to descend, the horizontal cutting knife 631 extends out of the groove of the sealing plate 623 under the action of the elastic connecting member 633 and cuts off the connecting part between the ends of two adjacent packaging bags. Finally, after the cutting is completed, the horizontal heat-sealing assembly 62 and the cutting knife assembly 63 start to reset and rise to the initial position under the action of the lifting drive assembly 53. By repeating the above steps, continuous heat sealing and cutting of the packaging bag can be completed.

[0069] It is worth mentioning that the operator can adjust the descending position of the lifting and guiding assembly, the heating time and heating temperature of the horizontal heat-sealing assembly 62 through the relevant buttons on the control panel 101, and can also adjust the cutting force of the cutting knife assembly 63 according to the material of the packaging bag to meet different packaging requirements.

[0070] In this embodiment, a control device 10 is further provided on the frame 1. The control device 10 includes a control panel 101 and an intelligent temperature control system (not shown in the figure). The control panel 101 is internally provided with a PLC controller; the intelligent temperature control system (not shown in the figure) is cooperatively connected with the horizontal heat-sealing assembly 62, and the intelligent temperature control system (not shown in the figure) is composed of a temperature sensor, a heating element, a refrigerating element and a control module. The temperature sensor, the heating element and the refrigerating element are all electrically connected to the control module, and the control module is communicatively connected to the PLC controller.

[0071] Specifically, during the horizontal heat sealing process, the temperature sensor of the intelligent temperature control system (not shown in the figure) collects the temperature data of the packaging area in real time and transmits it to the control module. The control module compares the real-time temperature with the preset optimal temperature range. If the temperature is lower than the lower limit, the control module activates the heating element to raise the temperature of the packaging area; if the temperature is higher than the upper limit, the control module activates the refrigeration element to lower the temperature of the packaging area. Through the precise control of the intelligent temperature control system (not shown in the figure), it is ensured that the temperature of the horizontal heat sealing is always in the best state, improving the heat sealing quality.

[0072] In addition, it is worth noting that the packaging machine of the present invention is equipped with an automatic cleaning and maintenance system. The automatic cleaning and maintenance system includes an automatic cleaning nozzle, a collection tank, and an intelligent lubrication device. The automatic cleaning nozzle is electrically connected to the control device 10; after the production is completed, the automatic cleaning program is started, and the cleaning nozzle sprays a special cleaning liquid to thoroughly wash the inside of the equipment. The waste liquid after washing is recycled and treated through the collection tank. At the same time, the intelligent lubrication device automatically adds lubricant to components such as bearings and chains according to the equipment operation duration and load conditions, ensuring the long-term stable operation of the equipment and reducing the frequency and intensity of manual maintenance.

[0073] As Figure 13 shown, the packaging method of the fragrance card pillow packaging machine in the present invention includes the following steps:

[0074] S1. Automatic feeding and positioning: Stack the fragrance cards in the card storage bin 22. After sorting by vibration feeding, the side baffle 2423 of the automatic card sending component 24 automatically adjusts the spacing based on the size of the fragrance card, and cooperates with the rotation of the card dialing wheel 243 to separate single fragrance cards, which are then guided and conveyed to the packaging station 322 through the card storage box 242;

[0075] S2. Synchronous conveying and monitoring: The conveyor belt 32 of the fragrance card conveying mechanism 3 receives the fragrance cards and is constantly conveyed at a constant speed by the synchronous wheel drive assembly 33. During this period, the photoelectric sensor 34 monitors the position and attitude of the fragrance cards in real time;

[0076] S3. Double-sided quantitative fragrance dropping: When the fragrance card is conveyed by the conveyor belt 32, the upper fragrance dropping component 7 drives the metering pump 74 through the PID controller to extract a quantitative amount of fragrance from the fragrance storage tank 72 and evenly spray it onto the upward-facing side of the fragrance card through the atomizing nozzle 73; when the photoelectric eye detector 116 recognizes that the fragrance card reaches below the fragrance card flipping component 11, the lifting cylinder 115 drives the flipping clamping plate 112 to descend, and the picking suction cup 117 adsorbs the fragrance card and flips it 180° and then accurately drops the fragrance card back onto the conveyor belt 32; repeat the fragrance dropping step to complete double-sided permeation fragrance dropping;

[0077] S4. Dynamic bag making: The fragrance card bag making mechanism 4 adjusts the film roll tension according to the size of the fragrance card, and forms a three-sided open packaging bag from the film roll through the bag making and forming component 9, and the fragrance card conveying mechanism 3 pushes the fragrance card into the bag;

[0078] S5. Longitudinal pre-sealing positioning: The longitudinal sealing mechanism 5 of the scented card packaging tightens both sides of the packaging bag through the film pulling assembly 51, and completes the side pre-sealing through the longitudinal sealing assembly 52 to form a continuous bag body, and conveys it to the next process;

[0079] S6. Vacuum exhaust sealing: Before the end of the packaging bag is sealed, the scented card enters the vacuum chamber 81. The push plate 83 descends under the drive of the transverse sealing and cutting mechanism 6 of the scented card, and discharges the excess air in the scented card packaging bag; at the same time, the vacuum pump 82 is started to extract the air in the vacuum chamber 81 to form a vacuum environment. When the vacuum degree reaches the set value, the packaging machine seals and cuts the end in a vacuum state;

[0080] S7. Intelligent transverse sealing and cutting: The transverse heat sealing assembly 62 descends along the lifting guide assembly 61 to complete the heat sealing of the packaging bag, and at the same time completes the cutting between the ends of two adjacent packaging bags through the cutting knife assembly 63; among them, the intelligent temperature control system (not shown in the figure) uses a temperature sensor to collect the temperature data of the packaging area in real time and transmits it to the control module; the control module compares the real-time temperature with the preset optimal temperature range. If the temperature is lower than the lower limit, the control module starts the heating element to raise the temperature of the packaging area; if the temperature is higher than the upper limit, the control module starts the refrigeration element to lower the temperature of the packaging area;

[0081] S8. Quality inspection and discharging: After the scented card is vacuum-packed, the sealing integrity is verified by a vision detector, and the qualified products are sorted by the discharging mechanism, and the packaging process is completed after boxing.

[0082] Specifically, an electrostatic elimination device can also be set between steps S2 and S4. The electrostatic elimination device includes an ion wind rod, a wind rod bracket and a power drive component. The wind rod bracket is fixed on the conveying frame 31 and is located between the conveying frame 31 and the former 92 assembly; the ion wind rod is rotatably installed on the wind rod bracket and is electrically connected to the power drive component; the static electricity on the surface of the scented card is eliminated by the ion wind rod to prevent the film material from being adsorbed and shifted by the static electricity existing on the surface of the scented card when the scented card enters the packaging bag, thus affecting the subsequent packaging effect.

[0083] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore: All equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
