Description

Technical Field

[0001] This invention relates to the field of oral soluble film packaging machine technology, and specifically to an oral soluble film packaging machine. Background Technology

[0002] Orally dissolving films are the latest generation of oral medications available worldwide. A single film is about the size and thickness of a postage stamp. To take the medication, place the film on or under the tongue; it dissolves completely in saliva within 10 to 60 seconds, allowing for rapid administration without the need for water.

[0003] Most oral dissolving films are first dried into a film using a film-making machine and then adhered to a base film. A packaging machine then packages them. The base film and the material film are first cut into multiple strips, then the material film is cut to equal lengths. The material film is then peeled from the base film, and two layers of packaging film are heat-sealed over the material film. Finally, it is cut into finished pieces. Patent CN216581311U discloses a packaging machine for quick-dissolving film agents, including a base film unwinding mechanism for unwinding the base film with the material film, and a mechanism for unwinding the material film... The system includes: a correction mechanism for correcting the bottom film of the packaging film; a slitting mechanism for cutting the top film of the bottom film with the packaging film; a slitting mechanism; a traction mechanism for pulling the slit film; an unwinding mechanism for unwinding the top packaging film; a cutting mechanism for cutting the film pulled by the traction mechanism to the same length; a bottom film winding mechanism for winding the bottom film after the peeled-off film; and a bottom packaging film unwinding mechanism for unwinding the bottom packaging film. The quick-dissolving film packaging machine, which includes a heat-sealing mechanism for heat-sealing the film and the lower packaging film, a waste collection device, a packaging traction mechanism, a punching mechanism, and a waste discharge and rejection device, has the following disadvantages in actual use: 1. The slitting mechanism cannot adjust the distance between the two slitting blades according to the width of the quick-dissolving film, and the slitting blades are pneumatic pressure cutters, resulting in a scattered air path distribution; 2. Separate upper and lower packaging film unwinding mechanisms are set up to unwind the upper and lower packaging films separately, increasing the cost of the equipment and the complexity of the process; 3. The cutting machine... 4. The upper and lower heat sealing components in the heat sealing mechanism cannot be easily replaced, making it unsuitable for packaging materials of various sizes and inconvenient to maintain; 5. The packaging film slitting process in the punching mechanism cannot easily adjust the blade size to match the material film size, and blade replacement is troublesome and inconvenient to maintain; 6. The waste detection method of the discharge rejection device has low detection efficiency and accuracy, cannot meet the needs of high-speed production, and the waste rejection method is not suitable for thin sheet products. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an oral dissolving film packaging machine to address the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a packaging machine for oral disintegrating film, comprising a frame, wherein the frame is provided with a bottom film unwinding mechanism for unwinding a bottom film with a material film, a bottom film slitting mechanism for slitting the bottom film into strips, a slitting mechanism for slitting the slitting bottom film, a material film cutting mechanism for cutting the material film into equal lengths, a bottom film peeling mechanism for peeling the bottom film from the material film, a bottom film winding mechanism for winding the peeled bottom film, a packaging film unwinding mechanism for unwinding the packaging film used for packaging the material film, a heat sealing mechanism for heat sealing the packaging film on the upper and lower sides of the material film, and a mechanism for heat sealing the packaging film... The packaging film slitting mechanism, the packaging film cutting mechanism for equal-length cutting of packaging film, and the waste rejection mechanism are characterized in that: the material film cutting mechanism includes a cutting bracket, the cutting bracket is provided with a rotatable cutting roller and a passive roller, the cutting roller is arranged parallel above the passive roller, the two ends of the cutting roller are provided with height adjustment components for adjusting its installation height, a lifting plate is provided between the two height adjustment components, the two sides of the cutting bracket are provided with adjustment grooves for placing the two ends of the cutting roller, the adjustment grooves and the upper end of the cutting bracket are both open, and the cutting bracket is provided with a cover plate that is detachably connected to it.

[0006] The present invention having the above features: a detachable cover plate is provided at the upper end of the cutting bracket and the adjustment groove. When it is necessary to replace or repair the blade, simply remove the cover plate and take the cutting roller out from inside the cutting bracket by raising the plate, which facilitates the replacement or repair of the blade outside the equipment.

[0007] A further feature of the present invention is that the height adjustment assembly includes movable blocks disposed at both ends of the cutter roller and an adjustment block disposed on the outer wall of the cutting bracket. The upper end face of the adjustment block is provided with an installation groove for the movable block to be inserted. An adjustment screw is passed through the movable block and the adjustment block. The movable block is movably located in the adjustment groove. The movable block reciprocates vertically along the adjustment groove as the adjustment screw rotates.

[0008] The present invention, which has the above-mentioned features, consists of an adjusting screw and a moving block that cooperate to form a screw-like assembly. By rotating the adjusting screw, the moving block moves up and down in the adjusting groove, thereby adjusting the cutting gap between the cutter roller and the driven roller to adapt to different material film thicknesses and improve the applicability of the cutter.

[0009] A further feature of this invention is that the rejection mechanism includes multiple conveying tracks, with the input ends of the multiple conveying tracks converging and the output ends radiating outwards. The output ends are connected to each other via connectors. The upper and lower surfaces of the conveying tracks are provided with a number of air holes that can adsorb materials. At least one set of rejection components is mounted on the upper surface of the conveying tracks. The rejection components include a rejection seat, a photoelectric switch for detecting whether waste has reached the rejection seat, and nozzles located on both sides of the conveying tracks to blow away materials. The photoelectric switch and the nozzles are both mounted on the rejection seat, and the air outlet of the nozzles faces the lower surface of the conveying tracks.

[0010] The present invention, possessing the above-mentioned features, involves the following: Before entering the conveyor track, the packaged oral dissolving film is detected by a front-end camera to determine if it is defective. If it is determined to be defective, a signal is fed back to a photoelectric switch. The finished product is detected by the photoelectric switch, and at this time, the nozzle blows air off it, completing the defect rejection process. The combination of photoelectric switch and camera detection is suitable for thin-sheet oral dissolving films, improving the accuracy of defect detection. The nozzle removes the oral dissolving film adsorbed on the lower surface of the conveyor track, achieving the function of targeted defect rejection, allowing one conveyor track to transport multiple products, thus improving production efficiency. The conveyor track with adsorption function is suitable for thin-sheet oral dissolving films with very small mass, ensuring the film adheres tightly to the conveyor track and preventing displacement during high-speed travel. Multiple conveyor tracks are set up to simultaneously transport multiple finished products, improving production efficiency. The input ends of multiple conveyor tracks are joined together to connect to the previous process, while the output ends are separated. After the finished products enter the conveyor tracks side-by-side, they gradually disperse, facilitating subsequent defect rejection and preventing accidental damage.

[0011] A further provision of the present invention is that the heat sealing mechanism includes a heat sealing frame, on which several sets of heat sealing components are arranged side by side. Each heat sealing component includes an upper heat sealing element and a lower heat sealing element. The lower heat sealing element is mounted on the heat sealing frame via a lifting plate.

The upper mounting plate is provided with an insertion strip that inserts into the insertion groove. The upper cold water plate and the upper mounting plate are detachably connected by a first disassembly component. The upper mounting plate, the upper heat insulation plate, the upper heating plate and the upper heat sealing component are connected by a connector. The first disassembly component includes a handle seat fixedly connected to the upper cold water plate and a limiting seat fixedly connected to the upper mounting plate. The handle seat and the limiting seat are connected by an indexing pin.

[0012] The present invention, possessing the above-mentioned features, includes: a first disassembly assembly between the upper cooling water plate and the upper mounting plate, restricting the movement of the upper mounting plate relative to the upper cooling water plate; when the upper heat seal needs to be disassembled, the restriction of the upper mounting plate by the first disassembly assembly is released; the pressure strip and insertion groove provided between the upper cooling water plate and the upper mounting plate allow the upper mounting plate to be pulled out along its length without restriction; the upper heat insulation plate, upper heating plate, and upper heat seal are pulled out together with the upper mounting plate, facilitating the replacement and maintenance of the upper heat seal; when the indexing pin is in its original state, its end is inserted into the limiting seat, and the upper mounting plate is fixedly connected to the limiting seat; under the restriction of the indexing pin, the upper mounting plate cannot be freely pulled out; rotating the indexing pin removes the limitation on the limiting seat, and the upper mounting plate connected to it can be freely pulled out after the limiting seat is no longer restricted; through the cooperation of the handle seat, the limiting seat, and the indexing pin, a detachable connection between the upper cooling water plate and the upper mounting plate is achieved.

[0013] A further feature of the present invention is that the lower heat sealer is connected to the lifting plate via a second connecting assembly, and the lower heat sealer is detachably connected to the second connecting assembly via a second disassembly assembly. The second disassembly assembly includes a disassembly seat that is fixedly connected to the lower heat sealer. A fixing member is detachably installed on the disassembly seat. The fixing member passes through the disassembly seat and is detachably connected to the second connecting assembly. The disassembly seat is also provided with a handle.

[0014] The present invention, which has the above features, achieves a detachable connection between the lower heat seal and the second connecting component by setting a second disassembly component, which can disassemble and remove the lower heat seal for easy replacement or maintenance; when the fixing component is in its original state, the disassembly seat and the second connecting component are connected at the same time. After the fixing component is disassembled, the lower heat seal can be removed from the heat sealing mechanism by pulling the handle. The second disassembly component has a simple structure and is easy to operate.

[0015] A further feature of the present invention is that the packaging film unwinding mechanism includes an unwinding frame, on which a feeding component for placing packaging film rolls, a splicing platform for splicing the two rolls end to end, a packaging film slitting component for dividing the packaging film in half, an upper guide component for pulling one half of the packaging film upwards, and a lower guide component for pulling the other half of the packaging film downwards are provided along the unwinding direction of the packaging film. The splicing platform is located above the feeding component, the upper guide component is located at the upper end of the unwinding frame, and the lower guide component is located at the lower end of the unwinding frame.

[0016] The present invention, possessing the above-mentioned features, separates the packaging film unwinding mechanism from other parts of the oral soluble film packaging machine, thus not occupying internal machine space; by setting a packaging film slitting component after the feeding component, the packaging film is divided into two parts, and upper and lower guide components are used to pull the packaging film upward and downward respectively, realizing the function of one packaging film unwinding mechanism to simultaneously transport upper and lower packaging films; a splicing platform is set between the feeding component and the packaging film slitting component, simplifying the packaging film unwinding process and the overall structure of the unwinding mechanism, and reducing equipment costs.

[0017] A further feature of the present invention is that the upper guide assembly includes a guide frame vertically fixed on the unwinding machine frame and several traction rollers horizontally arranged on the guide frame. Guide rails are provided on both vertical sides of the guide frame. Guide screws are slidably connected to the guide rails. A reversing reducer is connected to the end of the guide screw. A connecting rod is connected between the two reversing reducers. An adjusting roller is connected between the beginnings of the two guide screws.

[0018] The present invention, which has the above features, has an upper packaging film that passes over an adjusting roller from below. By adjusting a variable-direction reducer, the adjusting roller moves up and down along a lead screw, thereby adjusting the length of the unfolded upper packaging film, which facilitates subsequent processes.

[0019] A further feature of the present invention is that the packaging film slitting mechanism includes a packaging film slitting bracket, the packaging film slitting bracket having a rotatable support roller and a cutter assembly suspended above the support roller, the support roller and the cutter assembly cooperating to slit the packaging film, one end of the support roller passing through the packaging film slitting bracket and connected to a drive source, and the other end passing through the packaging film slitting bracket and placed inside a housing, the housing being detachably connected to the packaging film slitting bracket, and the cutter assembly including a cutter slide rail disposed on the packaging film sliding bracket, with a plurality of cutters slidably disposed on the cutter slide rail.

[0020] The present invention, which has the above-mentioned features, allows for the following when packaging material films of different sizes: simply remove the cover, take the support roller out of the slitting bracket, change the size of the support roller, and adjust the distance between the two cutters to adapt to material films of different sizes. The blade replacement is convenient, and the blade repair and maintenance are also convenient, which improves production efficiency and reduces production costs.

[0021] A further feature of the present invention is that: the packaging film slitting bracket is provided with a waste collection component at one end of the packaging film output, the waste collection component includes two waste racks, the upper end of the waste rack is provided with a waste wheel that can be rotatably provided, the bottom of the packaging film slitting bracket is provided with a waste slide rail, the waste slide rail is provided with a waste groove, and the base of the waste rack is provided with a waste pulley that can be embedded in the waste groove.

[0022] The present invention with the above features: In order to ensure that the material film can be completely wrapped, the size of the packaging film is often larger than the size of the material film, and waste will be generated during the cutting process. By setting up a waste collection component, the waste is wrapped around the waste wheel to complete the waste collection work; the waste rack is set separately and slidably connected to the cutting bracket, which makes it easy to match the size of the material film and improves the practicality of the waste collection component.

[0023] A further feature of this invention is that the bottom film slitting mechanism includes a bottom film slitting bracket, on which a rotatable pressure roller and a traction roller are mounted. The traction roller is arranged parallel above the pressure roller. The bottom film slitting bracket also includes a cutter seat, on which multiple equally spaced slitting blades are mounted. The cutter seat is located at the material inlet end of the bottom film slitting bracket and is arranged along the length of the pressure roller. The two sides of the cutter seat are inwardly inclined surfaces. The slitting blades are provided with slots for engaging with the cutter seat. The inner walls of the slots are set as inclined surfaces that adhere to the cutter seat. The slitting blades and the cutter seat are detachably connected by fasteners. An air passage seat is provided below the bottom film slitting bracket and on the same side as the cutter seat. The air passage seat is arranged along the length of the pressure roller and has a plurality of air holes evenly distributed thereon.

[0024] The present invention, possessing the above-mentioned features, includes: a cutter holder for mounting slitting blades; simply loosening the fasteners allows the slitting blades to move on the cutter holder, facilitating adjustment of the distance between the two slitting blades; the two sides of the cutter holder and the inner walls of the slots are designed as inwardly inclined surfaces, limiting the movement of the slitting blades mounted on the cutter holder, ensuring they can only move along the cutter holder and not vertically, preventing the slitting blades from jumping during operation, thus affecting the slitting quality and lifespan; the air holes are concentrated on the air passage seat, avoiding a scattered air passage distribution; the air passage seat is located on the same side of the cutter holder, facilitating the connection of air pipes between the air holes and the slitting blades, reducing the length of the air pipes used; the corresponding arrangement of the air holes and slitting blades avoids air pipe crossings, improving the aesthetics of the bottom film slitting mechanism.

[0039] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0040] like Figure 1-13 The illustrated oral dissolving film packaging machine includes a frame 1, on which are provided a bottom film unwinding mechanism a for unwinding a bottom film with a material film, a bottom film slitting mechanism b for slitting the bottom film into strips, a slitting mechanism c for slitting the slitting bottom film into segments, a material film cutting mechanism d for cutting the material film into equal lengths, a bottom film peeling mechanism e for peeling the bottom film from the material film, a bottom film winding mechanism f for winding the peeled bottom film, a packaging film unwinding mechanism g for unwinding the packaging film used to package the material film, a heat sealing mechanism h for heat sealing the packaging film on the upper and lower sides of the material film, a packaging film slitting mechanism i for slitting the packaging film into strips, a packaging film cutting mechanism j for cutting the packaging film into equal lengths, and a waste rejection mechanism k.

[0041] The bottom film slitting mechanism b includes a bottom film slitting bracket b1 and a plurality of slitting blades b2 arranged at equal intervals. The bottom film slitting bracket b1 is provided with a cutter seat b3 for mounting the slitting blades b2. The cutter seat b3 is located at the material inlet end of the bottom film slitting bracket b1. The two sides b31 of the cutter seat b3 are inclined surfaces that face inward. The slitting blades b2 are provided with a slot b21 that engages with the cutter seat b3. The inner walls on both sides of the slot b21 are set as inclined surfaces 211 that are in contact with the cutter seat b3. The slitting blades b2 and the cutter seat b3 are detachably connected by fasteners.

[0042] The bottom film slitting bracket b1 is equipped with a rotatable pressure roller b4 and a first traction roller b5. The first traction roller b5 is arranged parallel above the pressure roller b4. One end of the pressure roller b4 is connected to a driving device (not shown in the figure), which is a servo motor. Traction roller lifting assemblies b6 are provided on both sides of the first traction roller b5 to change its height. The traction roller lifting assembly b6 includes a lifting plate b61 mounted on the bottom film slitting bracket b1. One end of the lifting plate b61 is hinged to the bottom film slitting bracket b1, and the other end is connected to a lifting cylinder b62. The piston rod of the lifting cylinder b62 is hinged to the lifting plate b61. The lifting cylinder b62 is connected to the bottom film slitting bracket b1. The bottom of the cutting bracket is hinged, and the two ends of the first traction roller b5 are fixedly connected to the lifting plate b61. The bottom of the bottom film cutting bracket b1 is provided with a material feeding groove b11 for the bottom film to pass through. The material feeding groove b11 is located between the cutter seat b3 and the pressure roller b4. Below the bottom film cutting bracket b1 and on the same side as the cutter seat b3, there is an air passage seat b7. The air passage seat b7 is arranged along the length direction of the pressure roller b4 and has a number of air holes b71 evenly distributed on it. Below the air passage seat b7, there are at least two mounting blocks b8. The mounting blocks b8 are provided with a first mounting groove b81. The auxiliary air passage seat b9 passes through the first mounting groove b81 and is connected to the mounting block by fasteners.

[0043] The bottom film enters from the feed chute and wraps around the pressure roller. The servo motor drives the pressure roller to rotate, and the piston rod of the lifting cylinder descends, causing the traction roller to press against the pressure roller. The bottom film moves forward under the traction of the pressure roller. The slitting knife works with the pressure roller to slit the bottom film. The slitting knife is a pneumatic pressure slitting knife, which can be connected to the air hole of the air circuit seat.

[0044] The material film cutting mechanism d includes a cutting bracket d1, within which a rotatable cutting roller d2 and a driven roller d3 are installed. The cutting roller d2 is arranged parallel to and above the driven roller d3. Height adjustment components d4 are provided at both ends of the cutting roller d2 to adjust its installation height. Adjustment grooves d11 are provided on both sides of the cutting bracket d1 for placing the ends of the cutting roller d2. The height adjustment components d4 include movable blocks d41 located at both ends of the cutting roller d2 and adjustment blocks d42 located on the outer wall of the cutting bracket d1. Each movable block d41 includes a movable block body d411 located within the adjustment groove d11 and an auxiliary block d412 detachably connected to the movable block body d411. The movable block body d411 is movably located within the adjustment groove d11. The upper end face of the adjustment block d42 is provided for the lower end face of the auxiliary block d412. The second mounting groove d421 is inserted into the end. An adjusting screw d43 is passed between the auxiliary block d412 and the adjusting block d42. The moving block d41 moves back and forth vertically along the adjusting groove d11 as the adjusting screw d43 rotates. A lifting plate d5 is connected between the moving block bodies at both ends of the cutter roller d2. Two symmetrically distributed lifting rings d7 are provided on the lifting plate d5. The upper ends of the adjusting groove d11 and the cutting bracket d1 are both open. The cutting bracket d1 is provided with a cover plate d6 that is detachably connected to it. Two symmetrical lifting rings d7 are provided on the diagonal line of the cover plate d6. The bottom of the cutting bracket d1 is provided with a base d10 that is slidably connected to it. The base d10 includes a first base d101 provided at the material input end and a second base d102 provided at the material output end. The two are set separately.

[0045] The cover plate d6 is provided with a lifting assembly d8 for raising the cutter roller d2. The lifting assembly d8 includes a lifting seat d81 fixedly connected to the cover plate d6 and a hinge seat d82 fixedly connected to the lifting plate d5. The two side walls of the lifting seat d81 are respectively embedded with a rotatable cam d83 and a rotating wheel d84. The cam d83 is connected to an operating handle d85 that can drive it to rotate. The cam d83 and the rotating wheel d84 are linked through a connecting column (not shown in the figure). A connecting rod d87 is hinged on the hinge seat d82. The other end of the connecting rod d87 is hinged to the connecting column. The cover plate d6 is also provided with two symmetrically distributed force adjustment screws d9. One end of the force adjustment screw d9 passes through the cover plate d6 and is fixedly connected to the moving block body d411.

[0046] The material film passes between the cutter roller and the driven roller along with the base film. The cutter roller cuts the material film to the same length using a pressure cut method. When the thickness of the material film to be cut changes, rotating the adjusting screw moves the moving block up or down along the adjusting groove to change the cutting depth of the cutter roller. Moving the moving block up increases the cutting gap between the cutter roller and the driven roller, suitable for thicker material films; conversely, moving the moving block up increases the cutting gap, suitable for thinner material films. When it is necessary to change the cutting force of the cutter roller, operating the force adjusting screw increases or decreases the pressure on the cutter roller, thereby adjusting the cutting force. When passing through... When the bottom film between the cutter roller and the driven roller breaks, the operating handle is turned to rotate the cam. The cam moves the connecting rod upward, which in turn moves the lifting plate upward. The cutter roller connected to the lifting plate is lifted, making it easier for the bottom film to pass through. When the width of the material to be cut changes or the cutter roller is damaged, the cutting bracket is pulled away from the machine frame. Then, the cover plate is lifted with the help of equipment. The moving block body is then disconnected from the auxiliary block. Finally, the lifting plate is lifted, and the cutter roller leaves the cutting bracket with the lifting plate for subsequent blade replacement or maintenance.

[0047] The packaging film unwinding mechanism g includes an unwinding frame g1. On the unwinding frame g1, along the unwinding direction of the packaging film, there is a feeding component g2 for placing packaging film rolls, a splicing platform g3 for splicing two rolls end to end, a tension control component g7, a packaging film slitting component g4 for splitting the packaging film in half, an upper guide component g5 for pulling one half of the packaging film upwards, and a lower guide component g6 for pulling the other half of the packaging film downwards. The splicing platform g3 is located above the feeding component g2, the tension control component g7 is located below the packaging film slitting component g4, the upper guide component g5 is located at the upper end of the unwinding frame g1, and the lower guide component g6 is located at the lower end of the unwinding frame g1.

[0048] The feeding assembly g2 includes a feeding rod g21 horizontally arranged in the unwinding frame g1. Both ends of the feeding rod g21 are provided with connecting plates g22 that are detachably connected to the unwinding frame g1. The connecting plates g22 are inserted into the feeding rod g21. One end of the feeding rod g21 is connected to an unwinding motor g23 that drives its rotation.

[0049] The packaging film slitting assembly g4 includes a knife holder g41 connected to the unwinding frame g1, an auxiliary cutting roller g42 horizontally arranged on the upper end of the knife holder g41, a cutting wheel g43 at the center of the knife holder g41, and a shearing groove g421 adapted to the cutting wheel g43 on the auxiliary cutting roller g42.

[0050] The tension control assembly g7 includes a tension frame g71, with tension swing arms g72 hinged to the inner walls on both sides of the tension frame g71, and tension rollers g73 connected between the tension swing arms g72.

[0051] The upper guide assembly g5 includes a guide frame g51 vertically fixed on the unwinding frame g1 and several second traction rollers g52 horizontally arranged on the guide frame g51. Guide slide rails g53 are provided on both vertical sides of the guide frame g51. Guide screws g54 are slidably connected to the guide slide rails g53. A reversing reducer g55 is connected to the end of the guide screw g54. A connecting rod g56 is connected between the two reversing reducers g55. The connecting rod keeps the reversing reducers on both sides working synchronously. An adjusting roller g57 is connected between the beginning ends of the two guide screws g54. The lower guide assembly 6 includes several second traction rollers g52.

[0052] The packaging film roll is threaded onto the feeding rod. After passing through the splicing platform, the packaging film enters the tension control component. The packaging film then moves downwards around the tension roller. The tension roller, following the movement of the packaging film, drives the tension swing arm to rotate around the tension frame, thereby adjusting the tension of the packaging film to prevent it from being too tight or too loose. The packaging film leaves the tension control component and enters the packaging film slitting component, passing between the cutter wheel and the auxiliary cutter roller. The cutter wheel presses the packaging film into the shearing groove of the auxiliary cutter roller, splitting the packaging film into an upper packaging film and a lower packaging film. The upper packaging film moves upwards into the upper guide component, and the lower packaging film moves downwards into the lower guide component. The upper packaging film moves downwards around the adjusting roller. By adjusting the variable direction reducer, the screw rotates, which in turn moves the adjusting roller up and down, changing the length of the unfolded packaging film to facilitate subsequent processing. Both the upper and lower packaging films leave the packaging film unwinding mechanism under the traction of the traction roller and enter the next process. If the current packaging film roll is exhausted, the feeding rod is disassembled and a new roll is installed. The new roll is then spliced ​​to the end of the previous roll through the splicing platform to continue working.

The second passive roller i82 is evenly distributed with a number of silicone wheels i65.

[0062] The packaging film containing the material film (hereinafter referred to as the material) enters from the first packaging film traction device and passes sequentially through the support roller and the cutter assembly, the waste collection assembly, and the second packaging film traction device. When entering the first packaging film traction device, the first cylinder can drive the slider to move along the slide groove, and the material feeding gap between the first active roller and the first passive roller can be changed according to the thickness of the material film. When passing through the film, the first passive roller can also be raised. After the material enters the support roller, the model of the support roller can be changed according to the required width of the material film. Simply remove the cover and take the support roller out of the packaging film slitting bracket for replacement. Adjust the position of the cutter on the cutter slide rail, and at the same time match the shearing groove on the support roller with the width of the material film. The cutter presses the material into the shearing groove and cuts the material into strips. The material enters the second packaging traction device, and the second cylinder can be driven to lift the second passive roller. The material feeding gap between the second active roller and the second passive roller can be changed according to the thickness of the material film.

[0063] The rejection mechanism k includes multiple conveyor tracks k1, with their input ends k11 converging and output ends k2 radiating outwards. Each pair of output ends k2 is connected by a connector k2. A conveyor belt k3, capable of rotating cyclically along each conveyor track k1, is wound around it. A motor k8 is connected to one of the connector k2 of the conveyor track, driving the connector k2 to rotate, which in turn drives the connector k3 connected to it to rotate. Both ends of the conveyor track k1 are equipped with transmission components k13 that rotate with the connectors and propel the conveyor belt forward. Air holes k31 are evenly distributed on the conveyor belt k3, ensuring that both the upper and lower surfaces of the conveyor track k1 have air holes k31. Several positioning seats k4, spaced apart along the length of the conveyor track k1, limit the deviation of the conveyor belt k3. The conveyor track k1 is a vacuum adsorption track, and its upper surface has three spaced rejection points along the conveying direction. Component k5 consists of, in sequence, a forced rejection component k5a, a qualified product rejection component k5b, and a defective product rejection component k5c. The rejection component k5 includes a rejection seat k51, a photoelectric switch k52 for detecting whether the material is qualified, and nozzles k53 located on both sides of the conveyor track k1 to blow the material off. The rejection seat k51 is detachably connected to the conveyor track. The direction of the conveyor track forward is set as forward, and the opposite direction is set as backward. The photoelectric switch k52 is installed on the rear side of the rejection seat k51, and the nozzles k53 are installed on the front side of the rejection seat k51. The air outlet of the nozzles k53 is set towards the lower surface of the conveyor track k1. A support seat k6 is suspended on the upper surface of the conveyor track k1. The support seat k6 is set along the width direction of the conveyor track k1. One end of the support seat k6 is connected to the frame of the oral soluble film packaging machine, and the other end is suspended. The support seat k6 has a connecting groove k61 for the upper end of the rejection seat k51 to be installed.

[0064] The system employs six conveyor tracks. Packaged finished products enter the rejection mechanism in rows of six. The conveyor tracks increase the spacing between the finished products, allowing multiple rows to enter sequentially. This ensures that multiple finished products are spaced out on each conveyor track. Before entering the conveyor track, finished products are detected by cameras to determine if they are defective. If a product is deemed acceptable, a signal is sent to a photoelectric switch within the acceptable product rejection component. A nozzle within this component then blows the product off the conveyor track, causing it to fall into an acceptable product collection device located below the conveyor track. If a product is deemed defective, a signal is sent to a photoelectric switch within the defect rejection component. This component also blows the defective product off the conveyor track, causing it to fall into the defect collection device below the conveyor track, thus completing the rejection process. The forced rejection component is used to reject all finished products, regardless of whether they are acceptable or not; it does not normally operate.
