[0022] The following is combined with Figure 1-12 , an embodiment of a saffron pillow packaging machine and a packaging method thereof of the present invention is further described in detail.

[0023] A kind of saffron pillow packaging machine, such as Figures 1 to 3As shown, it includes a frame 1, a fragrance card feeding mechanism 2, a fragrance card conveying mechanism 3, a fragrance card bag making mechanism 4, a fragrance card packaging longitudinal sealing mechanism 5 and a fragrance card transverse sealing and cutting mechanism 6 which are sequentially arranged on the frame 1 along the processing direction, the fragrance card feeding mechanism 2 is provided with multiple groups, and the multiple groups of fragrance card feeding mechanisms 2 are equidistantly arranged on one side of the fragrance card conveying mechanism 3, and the end of the fragrance card feeding mechanism 2 is connected with the fragrance card conveying mechanism 3; a plurality of packaging stations 322 are arranged on the fragrance card conveying mechanism 3, and a flavor dropping component 7 for adding flavor is arranged above the packaging station 322; the fragrance card bag making mechanism 4 is installed in the frame 1, and the fragrance card bag making mechanism 4 is provided with a bag making and forming component 9 between the end of the fragrance card conveying mechanism 3 and the fragrance card packaging longitudinal sealing mechanism 5, and the bag making and forming component 9 is connected with the fragrance card bag making mechanism 4.

[0024] 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.

[0025] In this embodiment, if Figure 4 and 7As 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.

[0026] 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.

[0027] In this embodiment, if Figure 5 , 6As 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.

[0028] 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.

[0029] 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.

[0030] In this embodiment, if Figure 7As 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 .

[0031] The PID controller built into the atomizing nozzle 73 monitors the working status of the nozzle in real time, and automatically adjusts the atomizing effect of the nozzle according to the parameters such as the flow rate and pressure of the essence in the pipeline 75, so as to ensure that the essence can be evenly sprayed on the surface of the fragrance card. During the spraying process, the operator can observe the spraying of the essence through the observation window. If problems such as uneven spraying or nozzle blockage are found, the equipment can be stopped 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 according to the actual production situation through the relevant buttons on the control panel 101 to optimize the spraying effect of the essence.

[0032] In this embodiment, if Figure 4 and Figure 8 As shown, the incense card turning assembly 11 includes a lifting bracket 111, a turning clamping plate 112 arranged on the lifting bracket 111, and a rotating motor 113 for driving the turning clamping plate 112 to rotate. The lifting bracket 111 is composed of a plurality of lifting rods arranged in parallel, and 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 fixed plate, and an electric eye detector 116 for detecting incense cards is arranged on the L-shaped fixed plate; a telescopic electric cylinder 118 is connected between the turning clamping plates 112, and the telescopic electric cylinder 118 is fixedly connected to the L-shaped fixed plate, and the output shaft end of the telescopic electric cylinder 118 is drivingly connected to the turning clamping plate 112.

[0033] Specifically, in order to further increase the fragrance retention time of the scent card, it is necessary to spray fragrance on both sides of the scent card. The scent card after dripping fragrance on one side can be turned over by the scent card flipping assembly 11. Specifically, when the scent card is conveyed to the lower position of the scent card flipping assembly 11 through the conveyor belt 32, the electric eye detector 116 detects the scent card signal, and the lifting cylinder 115 drives the lifting sleeve 114 to descend, and controls the adjustment of the spacing between the flipping clamps 112 through the telescopic electric cylinder 118, so that the flipping clamps 112 can adjust the clamping force according to the size of the scent card; at the same time, in order to further increase the flipping clamps 112 In order to improve the grasping accuracy, a material taking suction cup 117 can be set on the flipping clamp 112 to cooperate with the fragrance card, which can also avoid damaging the fragrance card, and the flipping clamp 112 is controlled by the rotating motor 113 to flip. When the fragrance card is flipped 180° (that is, the bottom surface of the fragrance card originally attached to the conveyor belt 32 is turned upward, and the top surface with the fragrance is facing downward), the telescopic electric cylinder 118 controls the flipping clamp 112 to release the fragrance card, so that the fragrance card falls back into the packaging station 322 on the conveyor belt 32 and is transported again. At this time, the fragrance card completes the double-sided dripping of fragrance, further improving the uniformity of its fragrance dripping and effectively prolonging its fragrance retention time.

[0034] It is worth noting that, since the aroma card flip assembly 11 is installed on one side of the conveyor belt 32, when the flip clamp 112 descends to clamp the aroma 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 provided on the baffle plate 311, so that the maximum descending stroke of the flip clamp 112 is kept at the same height as the conveyor belt 32. At this time, the flip clamp 112 fits the surface of the conveyor belt 32 and uses the material suction cup 117 to accurately clamp the aroma card. In addition, the diameter of the material suction cup 117 on the flip clamp 112 determines the thickness of the object it clamps. Therefore, the thickness of the aroma card clamped by the aroma card flip assembly of the present application should be greater than 20mm, and the optimal range is between 20-50mm.

[0035] In this embodiment, if Fig. 9 , 10 As shown, the fragrance card bag making mechanism 4 is installed in the frame 1, and the fragrance card bag making mechanism 4 is located between the end of the fragrance card conveying mechanism 3 and the fragrance card packaging longitudinal sealing mechanism 5, and a bag making and forming component 9 is provided, and the bag making and forming component 9 is connected with the fragrance card bag making mechanism 4; the bag making and forming component 9 includes a forming support plate 91, a former 92 and a feed support plate 93, and the forming support plate 91 is fixed to the bottom end of the feed support plate 93; the feed support plate 93 is arranged at the same height as the conveyor belt 32; the former 92 is connected between the feed support plate 93 and the conveyor belt 32, and the former 92 is clamped on the forming support plate 91.

[0037] 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.

[0038] In this embodiment, if Fig.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.

[0040] The longitudinal sealing component 52 and the film drawing component 51 have the same structure, and the only difference is that a heating element is provided inside the longitudinal sealing component 52. After the two sides of the packaging bag are tightened, the heating element preheats the longitudinal sealing component to a suitable temperature, and then seals the sides of the packaging bag to be tightened by rolling, thereby completing the longitudinal sealing packaging of the packaging bag. In addition, the staff can adjust the heating temperature of the longitudinal sealing component 52 through the temperature adjustment button on the control panel 101 to meet the sealing requirements of packaging films of different materials.

[0041] In this embodiment, an exhaust component 8 for evacuating the air in the packaging bag is provided on the scent card transverse sealing and cutting mechanism 6; the exhaust component 8 includes a vacuum chamber 81, a vacuum pump 82 and a push plate 83, the vacuum chamber 81 is composed of a plurality of mutually spliced ​​card plates, and the vacuum chamber 81 is sleeved on the scent card transverse 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 by an exhaust pipe; the push plate 83 is arranged in the vacuum chamber 81, and a plurality of push plates 83 are provided, and the plurality of push plates 83 are respectively arranged on both sides and the top end of the gear conveyor belt, and one end of the push plate 83 is connected to the scent card transverse sealing and cutting mechanism 6, and the other end is provided with a sponge cushion 831.

[0042] Specifically, when the fragrance card completes longitudinal sealing and enters the vacuum chamber 81 along with the conveyor belt 32, the fragrance card transverse sealing and cutting mechanism 6 drives the push plate 83 to descend, and the push plate 83 squeezes out the excess air in the fragrance card packaging bag through the sponge cushion 831 during the descent process; after the push plate 83 completes the squeezing, the vacuum pump 82 is started to extract the air in the vacuum chamber 81 to form a vacuum environment. Among them, the two sides of the vacuum chamber 81 are separately provided with slots for input or output of packaging bags; at the same time, the operator can view the vacuum value in the vacuum chamber 81 in real time through the vacuum display screen on the control panel 101; when the vacuum reaches the preset value, the packaging machine completes the packaging sealing in a vacuum state. Then, the fragrance card transverse sealing and cutting mechanism 6 completes the sealing and cutting of the port of the packaging bag; not only does it avoid the problem of fragrance loss caused by the contact between the fragrance card and the air in the packaging bag, but it also significantly prolongs the fragrance retention time of the fragrance card.

[0043] In this embodiment, if Fig.12 As shown, the transverse sealing and cutting mechanism 6 for the fragrant card includes a lifting guide assembly 61, a transverse heat sealing assembly 62 and a cutter assembly 63.

[0045] Among them, the process of transverse sealing and cutting at the ends of the packaging bags is as follows: first, the heating plate 622 preheats the sealing plate 623 to a preset temperature, and as the packaging bags are transported to the bottom of the transverse sealing and cutting mechanism 6, the lifting guide assembly 61 drives the transverse heat sealing assembly 62 and the cutting knife assembly 63 to descend until the sealing plate 623 abuts against the packaging bag and performs heat pressure sealing on it, and then, as the lifting guide assembly 61 continues to descend, the transverse cutter 631 extends from 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, and finally, after the cutting is completed, the transverse heat sealing assembly 62 and the cutting knife assembly 63 begin to reset and rise to the initial position under the action of the lifting drive assembly 53, and repeat the above steps to complete the continuous heat sealing and cutting of the packaging bags.
