Description

Technical Field

[0001] The present invention relates to the field of automated knotting and packaging equipment, and particularly to an automatic string-passing and knotting device for scented cards. Background Art

[0002] As an in-vehicle fragrance product, a scented card releases fragrance through a card-shaped carrier, which is used to improve the in-vehicle air environment, cover up odors and provide a lasting fresh fragrance. During the production process of scented cards, it is necessary to punch holes at specific positions of the scented cards, thread and knot hanging ropes, so as to hang them on the rearview mirror in the car. The traditional work of threading and knotting scented cards mainly relies on manual operation. This method not only has low production efficiency, but also greatly increases the labor intensity of workers.

[0003] Although some string-passing and knotting machines have emerged in the prior art, for example, a Chinese patent with the publication number CN219928123U discloses a system for automatically simulating manual string-passing and knotting, including a feeding module, a transfer module, a punching module, multiple knotting modules, a hanging tag placing module, and a control system for automatically controlling the intelligent operation of each module. This device saves manpower to a certain extent and improves the efficiency of tying a single knot. However, it still has many limitations: on the one hand, this device uses the method of flat conveying and feeding of hanging tags, and the string-passing and knotting mechanism can only operate on a single scented card in sequence to complete continuous production, resulting in slow string-passing and knotting actions, seriously affecting the overall production efficiency; on the other hand, this device has strict requirements for the placement direction of hanging tags. When the hanging tags are placed in the wrong direction, the punching positions are extremely prone to errors, which greatly increases the rejection rate after string-passing and knotting, causing material waste and further reducing the production efficiency. In addition, this device lacks flexibility and is difficult to adapt to scented card products of different specifications or shapes, and its application range is greatly limited.

[0004] Therefore, it is of great practical significance to develop an automatic string-passing and knotting device for scented cards that can improve production efficiency, reduce the rejection rate, and enhance the flexibility of the device. Summary of the Invention

[0040] The following will further describe in detail an embodiment of an automatic stringing and knotting device for scented cards of the present invention with reference to the Figures 1-12 accompanying drawings.

[0041] An automatic stringing and knotting device for scented cards, as Figure 1 shown, includes a frame 1. A conveyor belt 2 is arranged on the frame 1. Along its conveying direction, a card feeding mechanism 3 for sequentially feeding single scented cards in order, a laser punching mechanism 4 for punching specific positions of the scented cards, a stringing mechanism 5 for stringing the punched positions of the scented cards, and a knotting mechanism 6 cooperating with the stringing mechanism 5 for winding the rope end to tie a knot are successively arranged on the conveyor belt 2. A scented card flipping and stacking mechanism 7 is arranged between the end of the conveyor belt 2 and the stringing mechanism 5.

[0042] Specifically, in this application, a conveyor belt 2 is provided on the rack 1, and a hairpin card mechanism 3, a laser punching mechanism 4, a string threading mechanism 5, and a knotting mechanism 6 are sequentially arranged on the conveyor belt 2. Additionally, a fragrance card flipping and stacking mechanism 7 is provided between the end of the conveyor belt 2 and the string threading mechanism 5, forming a complete automatic string threading and knotting process. During the specific string threading and knotting process, the hairpin card mechanism 3 is used to sequentially feed single fragrance cards in order, and the laser punching mechanism 4 punches holes in specific positions of the fragrance cards. Then, the fragrance card flipping and stacking mechanism 7 at the end of the conveyor belt 2 realizes the flipping, receiving, and pushing operations of the fragrance cards through the mutual cooperation of the flipping component 71, the receiving component 72, the pushing component 73, and the linear screw drive component 74. Finally, the string threading mechanism 5 passes the hanging rope through the punched positions of the fragrance cards, and the knotting mechanism 6 cooperates to complete the work of winding and knotting the rope ends. Through the mutual cooperation of the above technical features, the problems of low efficiency and high labor intensity in traditional manual operations are solved, thus realizing continuous and efficient production.

[0043] In this embodiment, as Figure 5 shown, the fragrance card flipping and stacking mechanism 7 includes a flipping component 71 for flipping the fragrance cards upside down, a receiving component 72 for receiving the fragrance cards and cooperating with the string threading mechanism 5 for string threading, a pushing component 73 for pushing the fragrance cards into the receiving component 72, and a linear screw drive component 74 for driving the lateral movement of the flipping component 71; the receiving component 72 and the string threading mechanism 5 are arranged on the same horizontal line, and the receiving component 72 is cooperatively connected with the pushing component 73.

[0044] Specifically, the flipping component 71 includes a flipping plate 711, a fixed seat 712, and a flipping cylinder 713. The bottom end of the fixed seat 712 is slidably connected to the linear screw drive component 74; the flipping cylinder 713 is fixedly installed on the fixed seat 712, and there is a hinge seat 716 drivingly connected between the flipping cylinder 713 and the flipping plate 711. The hinge seat 716 is rotatably connected to the output end of the flipping cylinder 713, and one side of the hinge seat 716 is fixed to the flipping plate 711; a plurality of positioning blocks 714 are arranged at the top end of the flipping plate 711 corresponding to the corner positions of the fragrance cards; and a convex block 715 is arranged between two adjacent positioning blocks 714 on the flipping plate 711.

[0045] Among them, as Figure 6 shown, the hinge seat 716 is composed of mounting plates fixed on both sides of the flipping cylinder 713 and a rotating shaft device rotatably connected between the mounting plates. A spur gear and a bearing are sleeved on the rotating shaft device, and one end of the spur gear is fixedly connected to the flipping plate 711; the output end of the flipping cylinder 713 is connected with a rack, and the rack meshes with the spur gear for driving. Under the drive of the flipping cylinder, while the rack makes a linear motion, it drives the gear to rotate, and when the gear rotates, it synchronously drives the flipping plate to rotate around the rotating shaft device, thus completing the flipping of the fragrance cards to the upright state.

[0046] Specifically, the working process of the flipping component 71 is as follows: The flipping component 71 makes a linear reciprocating motion through the linear screw drive component 74, and the sliding stroke is between the conveyor belt and the pushing component 73. When the flipping plate 711 moves below the conveyor belt, it automatically receives the flatly placed incense cards. Then, while sliding along the linear screw drive component 74 towards the pushing component 73, it uses the flipping cylinder 713 to drive the incense cards to flip through the hinge seat 716. During the flipping process of the incense cards, the positioning block 714 will limit the position of the incense cards. At the same time, there is an air hole in the center of the convex block 715, and the air hole is connected to the suction fan through a trachea. When the incense card is located on the flipping plate 711, under the adsorption effect of the suction fan, the incense card is adsorbed on the convex block 715 to prevent it from falling during the flipping process. When the hinge seat 716 rotates to the maximum stroke, at this time, the flipping plate 711 carries the incense card from the horizontal placement to the vertical setting; at the same time, when the flipping component 71 moves to the position of the pushing component 73, the pushing component 73 pushes the incense card from the flipping plate 711 into the receiving component 72, so as to stack multiple incense cards for unified stringing operation, improving the efficiency of stringing and knotting. The linear screw drive component 74 adopts the screw drive principle in the prior art, mainly driven by a motor to rotate the screw, so its structure and working principle will not be described in detail here.

[0047] In this embodiment, as Figure 5 shown, the receiving component 72 includes a material trough support block 721, a receiving fixture 722 and a baffle 723. The material trough support block 721 is fixed on the frame 1, and the top end of the material trough support block 721 is fixedly connected to the receiving fixture 722; a plurality of threading troughs 7221 for placing incense cards are equidistantly arranged in the receiving fixture 722, and the threading troughs 7221 penetrate both sides of the receiving fixture 722. The baffle 723 is arranged on one side of the receiving fixture 722 to prevent the incense card from falling from one side of the threading trough 7221, and one end of the baffle 723 is drivingly connected to a baffle cylinder 724. The baffle cylinder 724 is fixed to the top end of the receiving fixture 722 through a cylinder mounting plate 725, so that the baffle 723 moves up and down following the baffle cylinder 724 to control the opening and closing of the threading trough 7221.

[0048] In this embodiment, as Figure 5 shown, the pushing component 73 includes a pushing frame 731, a pushing cylinder 732, a pushing clamping plate 733 and a connecting plate 734. The pushing frame 731 is located on one side of the flipping component 71. The pushing cylinder 732 is installed on the pushing frame 731, and the output shaft end of the pushing cylinder 732 is drivingly connected to the connecting plate 734; the other side of the connecting plate 734 is fixedly connected to the pushing clamping plate 733; the pushing clamping plate 733 is adapted to the threading trough 7221, and a clamping groove 7331 for clamping the incense card is provided on the pushing clamping plate 733.

[0049] Specifically, the flipped incense card is pushed into the threading trough 7221 of the material receiving fixture 722; at this time, the material blocking cylinder 724 controls the material blocking plate 723 to move downward, blocking the incense card to prevent it from falling from one side of the threading trough 7221; the material blocking cylinder 724 is fixed to the top of the material receiving fixture 722 through the cylinder mounting plate 725, and can accurately control the lifting and lowering action of the material blocking plate 723.

[0050] In this embodiment, if Figure 7 As shown, the card issuing mechanism 3 includes a material storage rack 31, a flip card taking assembly 32 and a card separation and pushing assembly 33. The material storage rack 31 is fixed on the frame 1, and a fragrance card storage box 311 is obliquely fixed to the top of the material storage rack 31. The fragrance card storage box 311 is equipped with a storage slot 3111 for storing fragrance cards, and the two sides of the fragrance card storage box 311 are slidably connected with a material pressing assembly 34; the flip card taking assembly 32 is movably connected to the material storage rack 31, and the flip card taking assembly 32 is located below the fragrance card storage box 311; the card separation and pushing assembly 33 is fixed to the flip card taking assembly 32; the flip card taking assembly 32 extracts the fragrance card at the bottom of the fragrance card storage box 311, and pushes the taken out fragrance card to the conveyor belt 2 through the card separation and pushing assembly 33.

[0051] Specifically, the storage rack 31 is fixed on one side of the frame 1, and the aroma card storage box 311 is fixed on the top of the storage rack 31 at an angle of 30°. The storage trough 3111 inside the storage rack 3111 has a size of 250 mm in length and 120 mm in width, which can store a large number of aroma cards of different specifications and types, and a blocking block is set at the bottom of the storage trough 3111 to prevent the aroma cards from slipping out of the storage trough 3111. When the number of aroma cards in the aroma card storage box 311 decreases, the pressing component 34 presses down and abuts on the aroma cards, so that the aroma cards always maintain stable feeding, so as to facilitate card retrieval. The storage rack 31 provides a storage position for aroma cards, the flip card retrieval component 32 is responsible for extracting aroma cards from the storage trough 3111, and the card separation push component 33 pushes the extracted aroma cards onto the conveyor belt 2. Through the combination of these technical features, the problem of how to automatically remove the aroma cards from the storage box and push them onto the conveyor belt 2 can be effectively solved.

[0052] In this embodiment, if Figure 7 As shown, the flipping card retrieval assembly 32 includes a flipping frame 321, a material retrieval plate 322 and a rotating cylinder 323. The middle part of the flipping frame 321 is rotatably connected to the storage frame 31 through a rotating shaft, and one end of the flipping frame 321 is fixedly connected to the material retrieval plate 322, and the other end is drivingly connected to the output shaft end of the rotating cylinder 323; a plurality of material retrieval plates 322 are provided, and a vacuum suction cup 324 for grabbing the fragrance card is provided on each of the plurality of material retrieval plates 322.

[0053] Specifically, the flipping frame 321 is connected to the storage rack 31 through a rotating shaft. One end of the flipping frame 321 is fixedly connected to the card-taking plate 322, and the other end is drivingly connected to the output shaft end of the rotating cylinder 323. Four vacuum suction cups 324 are evenly distributed on the card-taking plate 322. The vacuum suction cups 324 are arranged towards the direction of the fragrance card storage box 311. By driving the rotating cylinder 323, the flipping frame 321 can rotate around the rotating shaft and drive the card-taking plate 322 to flip, so that the vacuum suction cups 324 can extract the fragrance card at the bottommost of the fragrance card storage box 311, and use the card-sorting and pushing assembly 33 to push the extracted fragrance card onto the conveyor belt 2, thereby realizing the automatic blanking of the fragrance card.

[0054] In this embodiment, as Figure 7 shown, the card-sorting and pushing assembly 33 includes a pushing plate 331, a pushing cylinder 332 drivingly connected to the pushing plate 331, and a cylinder fixing plate 333 for installing the pushing cylinder 332. The cylinder fixing plate 333 is fixedly connected to the flipping frame 321, and the output shaft end of the pushing cylinder 332 is drivingly connected to the pushing plate 331.

[0055] Specifically, through the coordinated work of the pushing plate 331, the pushing cylinder 332 and the cylinder fixing plate 333, under the drive of the pushing cylinder 332, the pushing plate 331 can push the fragrance card taken out from the storage box by the vacuum suction cups 324 onto the conveyor belt 2, thereby realizing the function of automatic feeding.

[0056] It should be noted that the pushing cylinder 332 can adopt common actuators such as an electric cylinder or a hydraulic cylinder, and the pushing plate 331 can be customized according to the size of the fragrance card to ensure the smoothness and accuracy of the pushing process.

[0057] Through the above technical means, the present application realizes the automatic extraction and pushing of the fragrance card through the mutual cooperation of the storage rack 31, the flipping card-taking assembly 32 and the card-sorting and pushing assembly 33, avoiding the inefficiency and high cost of manual operation. Compared with the prior art, the card-issuing mechanism 3 of the present application can more efficiently realize the automatic processing of the fragrance card, reduce manual intervention, improve production efficiency and product quality; and through an automated method, ensure that the fragrance card can be accurately positioned during the extraction and pushing process, reduce the rejection rate, and further improve the overall efficiency of the production line.

[0058] In this embodiment, as Figure 7As shown in the figure, the blanking component 34 includes linear slide rails 341 fixedly arranged on both sides of the incense card storage box 311, a sliding connection plate 342 connected to the linear slide rails 341, and a blanking plate 343 located inside the incense card storage box 311. The sliding connection plate 342 is horizontally slidably connected between the linear slide rails 341, and a blanking cylinder 345 is fixedly connected to one side of the sliding connection plate 342; the output shaft end of the blanking cylinder 345 is drivingly connected with a telescopic rod 344, and one end of the telescopic rod 344 penetrates through the sliding connection plate and is connected to the blanking plate 343.

[0059] Specifically, the blanking component 34 enables the sliding connection plate 342 to stably slide on both sides of the incense card storage box 311 through the linear slide rails 341. At the same time, the blanking plate 343 is connected to the sliding connection plate 342 through the telescopic rod 344, so that the blanking plate 343 can further extend the distance of its downward pressure through the telescopic rod 344. Furthermore, when the number of incense cards in the storage groove 3111 decreases, a stable pressure is still applied to the incense cards to prevent the incense cards from tilting or falling in the storage groove 3111. The output shaft end of the blanking cylinder 345 is drivingly connected to the blanking plate 343 through the telescopic rod 344, so that the blanking cylinder 345 can drive the blanking plate 343 to expand and contract, thereby realizing the effective pushing of the incense cards.

[0060] In this embodiment, as Figure 8 shown, the laser punching mechanism 4 includes a punching bracket 41, a displacement adjustment component 42 connected to the punching bracket 41 for adjusting the punching position, and a laser punching head 43 slidably connected to the displacement adjustment component 42. The punching bracket 41 is fixed on the frame 1 and spans above the conveyor belt 2; the displacement adjustment component 42 includes a horizontal guide rail 421, a guide plate 422, and a driving cylinder 423. The horizontal guide rail 421 is arranged along the length direction of the punching bracket 41.

[0061] Specifically, when the incense card is conveyed to the lower part of the laser punching mechanism 4 along with the conveyor belt 2, the driving cylinder 423 pushes the guide plate 422 to move on the horizontal guide rail 421 according to the punching position information of the incense card, adjusts the position of the laser punching head 43, and then the laser punching head 43 is started to complete the punching operation. Among them, the punching bracket 41 provides a stable support structure to ensure that the laser punching head 43 can be accurately positioned; the displacement adjustment component 42 enables the laser punching head 43 to accurately move according to the position of the incense card through the cooperation of the horizontal guide rail 421, the guide plate 422, and the driving cylinder 423, thereby realizing punching at different positions of the incense card. The high-precision and high-efficiency punching operation of the incense card is realized through laser technology, effectively solving the error caused by traditional mechanical punching and greatly improving the production efficiency of the incense card.

[0062] In this embodiment, if Figure 9 , 10 As shown, the rope threading mechanism 5 includes an unwinding drum 51 for unwinding the sling rope, a rope feeding assembly 52 for positioning and conveying the sling rope, and a rope pulling assembly 53 for adjusting the position of the rope head and tightening it. The unwinding drum 51 is fixed to the frame 1 by setting a fixing frame 511, and an arc-shaped baffle plate 512 is provided below the unwinding drum 51; the rope feeding assembly 52 includes a bracket plate 521, a rope feeding wheel 522 and a rope feeding needle 523, and a plurality of rope feeding wheels 522 are provided, and the plurality of rope feeding wheels 522 are arranged in an upper and lower manner on the bracket plate 521; the rope feeding needle 523 is fixed to the bracket plate 521 by setting a mounting block, and the rope feeding needle 523 is located between the upper and lower rope feeding wheels 522.

[0063] Specifically, after a plurality of incense cards are uniformly placed in the receiving trough 7221, the unwinding disc 51 releases the sling rope, the rope feeding wheel 522 rotates to drive the sling rope forward, and the rope feeding needle 523 is used for stable guidance to ensure that the sling rope is wound around the rope feeding wheel 522, and the rope is passed through the punching position of the incense card through the rope pulling assembly 53, thereby completing the rope threading action. Among them, the fixing frame 511 of the unwinding disc 51 can be in a variety of forms, for example, it can be fixed to the frame 1 by bolts, or fixed by welding, to ensure that the unwinding disc 51 does not shake during operation. The arrangement of the rope feeding wheels 522 can be adjusted according to specific needs. For example, rope feeding wheels 522 of different diameters and materials can be selected according to the thickness and material of the sling rope, and an elastic clamping member is connected to the bottom end of one of the rope feeding wheels 522 to facilitate adjusting the tightness of the rope feeding needle 523 under different circumstances.

[0064] In this embodiment, if Figure 10 As shown, the rope pulling assembly 53 includes a sliding rod seat 531, a rope pulling clamp 532, a rope threading mounting block 533 and a sliding rod cylinder 534. The sliding rod seat 531 is fixed on the frame 1, and the sliding rod seat 531 and the bracket plate 521 are located on the same horizontal line; the rope threading mounting block 533 is slidably connected to the sliding rod seat 531, and one side of the rope threading mounting block 533 is transmission-connected to the sliding rod cylinder 534; one end of the rope pulling clamp 532 is linked to the rope pulling cylinder 535, and the rope pulling cylinder 535 is fixed to the other side of the rope threading mounting block 533.

[0065] Specifically, the rope assembly 53 needs to straighten the rope and convey it along the position of the shank card for threading. The threading installation block 533 is provided with a rope loop, which is used to ensure that the rope head is straightened and convenient for threading. The slide rod seat 531 is used to provide a sliding track and stable support, and the slide rod cylinder 534 drives the threading installation block 533 to move along the slide rod seat 531, thereby ensuring that the rope loop can drive the rope to accurately locate the position of the shank card punching. The rope clamp 532 is used to clamp or loosen the rope to cooperate with the action of the threading installation block 533 to prevent the rope from retracting. The threading installation block 533 is slidably connected with the slide rod seat 531 to ensure that the rope loop can slide and extend into the threading trough 7221.

[0066] The working process of the rope threading mechanism 5 includes the following steps:

[0067] S1. Place the sling on the unwinding reel 51 and secure it;

[0068] S2. Pre-thread the end of the rope through the rope feed needle 523 and wrap it around the rope feed wheel 522 to adjust the tension, and then thread the rope end through the rope clamp 532 and the rope loop on the rope mounting block 533;

[0069] S3. After the incense cards are neatly arranged, the slide cylinder 534 drives the rope threading mounting block 533 to slide along the slide seat 531, and then accurately pulls the rope loop together with the lifting rope into the material receiving trough; at this time, the rope pulling cylinder 535 drives the rope pulling clamp 532 to clamp the lifting rope to prevent the lifting rope from retracting;

[0070] S4. After the rope passes through the rope threading hole of the shank, the slide cylinder 534 starts to drive the rope threading mounting block 533 to return to the initial position; at the same time, the stretching cylinder 535 drives the rope clamp 532 to loosen the rope, and the above operation is continued to cycle to achieve continuous rope feeding and rope threading actions.

[0071] In this embodiment, if Figure 11 , 12 As shown, the knotting mechanism 6 includes a winding bracket 61, a wire clamp assembly 62, a winding assembly 63 and a cutting assembly 64. The winding bracket 61 is arranged opposite to the position of the material receiving assembly. One end of the wire clamp assembly 62 is connected to the winding bracket 61, and the other end extends to the bottom of the material receiving assembly. The winding assembly 63 is provided in multiple groups, and the multiple groups of winding assemblies 63 are axially arranged on the winding bracket 61, and the winding assembly 63 is matched and connected with the wire clamp assembly 62. The cutting assembly 64 is arranged between two adjacent winding assemblies 63, and the cutting assembly 64 is horizontally installed on the winding bracket 61.

[0072] Specifically, the wire clamp assembly 62 includes a wire hook rod 621 and a multi-link assembly 622, one end of the wire hook rod 621 is provided with a hook groove, and the other end is transmission-connected to the multi-link assembly 622, and one end of the multi-link assembly 622 is connected to a driving source; wherein, the wire hook rod 621 is arranged corresponding to the number of material receiving troughs, and a connecting shaft 623 passes through the plurality of wire hook rods 621, so that the plurality of wire hook rods 621 can rotate synchronously; the initial position of the end of the wire hook rod 621 provided with the hook groove is located below the material receiving trough, and when knotting is required, the wire hook rod 621 rotates around the connecting shaft 623 under the drive of the multi-link assembly 622, and uses the hook groove to clamp the hanging ropes at both ends of the incense card, and after the wire hook rod 621 clamps the hanging rope, it continues to rotate until it is clamped into the winding assembly 63 with the hanging rope, thereby facilitating the winding and knotting operation of the hanging rope.

[0073] Specifically, the winding assembly 63 includes a rope beak 631, a rotating rod 632 and a rope winding motor 633. One end of the rope beak 631 is connected to the rotating rod 632, and a through hole is formed on the rope beak 631, in which a beak baffle 634 is movably connected; one end of the beak baffle 634 abuts against the rope beak 631, and the other end is transmission-connected to an opening and closing controller 635; the other end of the rotating rod 632 away from the rope beak 631 is transmission-connected to the rope winding motor 633; ​​so that when the rope is tied, the rope winding motor 63 The driving rotating rod 632 drives the rope winding beak 631 to rotate counterclockwise. Since the rope is pulled to the beak baffle 634 through the hook rod 621 in advance, the rope winding beak 631 drives the rope to rotate once to form a knot. At the same time, the opening and closing controller 635 drives the beak baffle 634 to open synchronously when the rope winding beak 631 rotates, so as to facilitate the rope on the other side to be pulled into the knot. Through the cooperation between the rope winding beak 631 and the beak baffle 634, the rope is quickly tied, and finally cut by the cutting component 64. Among them, the knotting method and working principle of the winding component 63 are similar to the claw-type knotter in the prior art.

[0074] Specifically, the cutting assembly 64 includes a cutting knife 641 and a driving member 642 for driving the cutting knife 641 to open and close. The driving member 642 is connected to the cutting knife 641 through a coupling, so that the rope is automatically cut after the knot is tied, which simplifies the operation steps and further improves the production efficiency. As a preferred embodiment, a sensor can be added to the cutting assembly 64 to detect the state of knotting completion, so as to accurately control the cutting time and avoid misoperation.

[0075] It is worth noting that the working process of the knotting mechanism 6 includes the following steps:

[0076] Wire clamping: The wire clamp assembly 62 rotates under the drive of the multi-link assembly 622, and places the rope to be tied between the winding assemblies 63;

[0077] Wire winding: Driven by the wire winding motor 633, the wire winding hook 631 rotates or swings around the clamped suspension rope to wind the wire into a coil.

[0078] Thread threading: While the wire winding hook 631 is winding the wire, the hook baffle 634 opens under the action of the opening and closing controller 635, and pulls the side of the suspension rope that has not formed a coil into the loop knot.

[0079] Tightening: After the thread threading operation is completed, the wire clamp assembly 62 rotates in the reverse direction to reset, and at the same time tightens the wire loop after knotting to make the wire form a firm knot. Then the wire winding hook 631 opens to release the knotted suspension rope.

[0080] Wire cutting: Before the wire winding hook 631 opens, the cutting assembly 64 drives the cutting knife 641 through the driving part 642 to cut at the positions of adjacent two knot heads, which is convenient for subsequent blanking.

[0081] Through the above technical solutions, the present application realizes the automation of the process of threading and knotting the incense card, which not only improves the production efficiency, but also reduces the error of manual operation and the production cost. Compared with the prior art, the knotting mechanism 6 of the present application is more reasonably designed, more compact in structure, and more convenient to operate, which can significantly improve the efficiency and accuracy of threading and knotting the incense card, reduce the rejection rate, and improve the product quality.

[0082] It is worth mentioning that a receiving groove 8 is provided at the position corresponding to the knotting mechanism 6 on the frame 1, and the receiving groove 8 is used to receive the incense card after threading and knotting. In the automatic threading and knotting device for incense cards, after the knotting mechanism 6 completes the threading and knotting of the incense card, a device is needed to receive the processed incense card. The receiving groove 8 is designed for this purpose. The function of the receiving groove 8 is to receive the incense card after threading and knotting to ensure that the incense card will not fall or be scattered, so that the entire production process is smoother. By setting the receiving groove 8, the problem of smoothly receiving the incense card after threading and knotting can be effectively solved, ensuring the continuity and efficiency of the production line.

[0083] Among them, the receiving trough 8 can adopt a variety of structural forms, such as a simple flat-bottomed trough, a trough with a guide structure, or a trough with a buffer structure. The flat-bottomed trough can directly receive the incense card, the guide structure can help the incense card slide smoothly into the trough, and the buffer structure can reduce the impact force when the incense card falls into the trough, and protect the integrity of the incense card. Specifically, the receiving trough 8 can be made of metal or plastic material with sufficient strength and durability. The size and shape of the receiving trough 8 can be customized according to the specifications of the incense card to ensure that the incense card can fall into the trough stably. By setting up the receiving trough 8, the problem of incense cards falling or scattering easily after knotting is completed is effectively solved, ensuring the continuity and stability of the production process; and it can automatically receive incense cards, avoiding manual intervention, and improving the automation level and production efficiency of the entire production line.

[0084] It is worth mentioning that the device of the present invention also includes a controller 9, which is fixed on the frame 1 and has a built-in PLC control module. The controller 9 is electrically connected to the card issuing mechanism 3, the laser punching mechanism 4, the rope threading mechanism 5, the knotting mechanism 6 and the flipping and stacking mechanism, respectively, so as to control the coordination of various mechanisms and improve work efficiency.

[0085] like Figures 2-4 As shown, the working process of the automatic stringing and knotting device of the present invention is as follows:

[0086] First, the scented cards to be strung and knotted are pre-stored in the scented card storage box 311 which is fixed obliquely on the top of the storage rack 31. The device is started by the controller 9, and the card issuing mechanism 3 starts to automatically load the cards. As the card taking process progresses, the number of scented cards decreases, and the pressing cylinder 345 in the pressing assembly 34 pushes the sliding connecting plate 342, which slides stably with the help of the linear slide rail 341, and drives the pressing plate 343 to move in the storage tank 3111 through the telescopic rod 344, so that the scented cards are always maintained in a position that is convenient for grabbing. At the same time, the flip cylinder 713 in the flip card taking assembly 32 is started, driving the flip rack 321 to rotate around the rotating shaft, so that the vacuum suction cup 324 on the taking plate 322 drops to the bottom of the scented card storage box 311, and uses negative pressure to absorb the scented cards. Then, the pushing cylinder 332 of the card pushing assembly 33 pushes the pushing plate 331 to accurately place the scented cards on the conveyor belt 2;

[0087] Then, the card goes forward with the conveyor belt 2 to the bottom of the laser punching mechanism 4, and the driving cylinder 423 pushes the guide plate 422 to slide on the transverse guide rail 421 according to the punching position information preset on the card, so as to accurately position the laser punching head 43 to the punching position, and then the laser punching head 43 is started, and the card material is instantly melted or vaporized by the high energy density laser beam to complete the punching operation;

[0088] Next, the punched incense cards are continuously conveyed by the conveyor belt 2 to the flipping and stacking mechanism. The linear screw drive assembly 74 drives the fixed seat 712 to move horizontally, so that the flipping plate 711 is located below the incense card. Subsequently, the flipping cylinder 713 drives the flipping plate 711 to flip around the hinge seat 716, and the synchronous belt flips the incense card to stand upright; when it is necessary to send the card, the pushing cylinder 732 pushes the pushing clamping plate 733 to clamp the incense card and uniformly push the punched end of the incense card into the threading slot 7221 of the receiving fixture 722. At the same time, the blocking cylinder 724 controls the blocking plate 723 to descend to block the incense card, so as to facilitate the threading operation of the threading mechanism 5;

[0089] Meanwhile, the unwinding reel 51 of the threading mechanism 5 releases the hanging rope. The arc-shaped baffle 512 prevents the hanging rope from winding. The rope feeding wheel 522 rotates under the traction of the rope pulling assembly 53 to adjust the tension of the hanging rope, and the rope pulling cylinder 535 controls the rope pulling clamp 532 to clamp the hanging rope and convey it forward, so that the hanging rope passes through the rope sleeve on the threading mounting block 533 and slides along the slide bar seat 531 under the action of the slide bar cylinder 534, so as to pass the hanging rope through the punched position of the incense card;

[0090] Finally, the knotting mechanism 6 cooperates synchronously. The rope winding motor 64 drives the rope winding eagle beak 62 to rotate to wind and knot the hanging rope. During the process, the eagle beak guide 63 and the eagle beak baffle 65 prevent the hanging rope from shifting. After the knotting is completed, the cutting assembly 66 cuts the hanging rope at one end of the eagle beak guide 63. The incense card with the rope threaded and knotted drops into the receiving slot 8. Thus, the entire process of threading and knotting the incense card is completed. The device continuously circulates this process to realize the automatic and efficient production of the incense card.

[0091] 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.
