[0039] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Combination Figures 1 to 24 As shown, an automatic filling machine includes a conveyor chain 1 mounted on a horizontal worktable, a cup-dropping mechanism 2, a feeding mechanism 3, a stirring mechanism 4, a film-picking and placing mechanism 5, a heat-sealing mechanism 6, a coding mechanism 7, and a transfer mechanism 8 arranged sequentially along the conveying direction of the conveyor chain 1. The conveyor chain 1 includes a chain support 11, two chains 12 that rotate synchronously in a circular motion on the chain support 11, and several mold plates 13 connected between the two chains 12. The mold plates 13 are provided with recesses 131 corresponding to the cups. The cup-dropping mechanism 2 includes a cup storage bin 21 and a cup-dropping device 22 for sequentially pushing the cups in the cup storage bin 21 to the corresponding recesses. The feeding mechanism 8... Structure 3 includes ten feeding devices (five on each side) arranged on both sides of the conveyor chain 1. A weighing mechanism 9 corresponding to the cup body is set between adjacent feeding devices on the same side. Stirring mechanism 4 includes a water injection device 41 and a stirring device 42. Film picking and placing mechanism 5 includes a film storage bin 51 and a film picking and placing device 52 for sequentially transferring the sealing film in the film storage bin 51 to the top of the corresponding cup body. Heat sealing mechanism 6 includes a heat sealing device 61 for hot-sealing the sealing film to the cup body. Coding mechanism 7 includes a first cup lifting device 71 and a coding gun 72. Transplanting mechanism 8 includes a second cup lifting device 81 and a transplanting device 82 for driving the second cup lifting device 81 to move horizontally.

[0041] In this technical solution, the workbench is assembled from conventional profiles and plates, and is kept level by adjustable feet. The workbench also includes a control device with conventional structures such as a PLC, solenoid valves, and relays. A chain support is fixed to the top surface of the workbench using conventional bolts to support the chain. The chain is made of conventional stainless steel and is connected to a mold plate via conventional lugs or angle irons to form a ring-shaped conveyor chain. The conveyor chain also includes conventional necessary structures such as a conveyor motor and sprockets. The mold plate has a recessed platform for placing the cup; the recessed platform has a countersunk hole structure, meaning the inner wall of the through hole forms a step to support the cup's rim. The diameter of the stepped section is 0.3mm larger than the cup body diameter and 5mm smaller than the cup rim flange diameter. After the cup body falls into the mold plate, the stepped section within the recessed platform supports the cup rim flange, thus fixing the cup body. During the stepping operation of the conveyor chain, the cup dropping device pushes the cup body from the storage bin into the mold plate directly below it. The cup body moves with the mold plate below the feeding device, which fills the corresponding powder into the cup body. During the filling process, the weighing device monitors the weight change of the cup body to ensure accurate filling volume. The feeding devices on both sides of the conveyor chain can fill the cup body with the same or different powders. Ten feeding devices can independently fill different powders into the same cup body, thus completing the process. To meet the ingredient requirements of the nutritional powder, when the cup containing the powder moves directly under the mixing mechanism, the water injection device first injects sterile water into the cup, and then the mixing device mixes the powder and sterile water evenly. After mixing, the cup moves directly under the film-receiving mechanism, which transfers the sealing film from the storage compartment to the top of the cup. To facilitate opening the sealing film during subsequent consumption, one side of the sealing film protrudes beyond the cup's rim, with the recessed area of ​​the mold plate corresponding to it to prevent the sealing film from shifting. After the cup and sealing film move directly under the heat-sealing device, the heat-sealing device heat-seals the sealing film onto the top of the cup, and then moves to the coding mechanism's station for the first extraction. The device removes the sealed cup from the mold plate, and a coding gun marks the product's relevant information on the side of the cup. After marking, the first extraction device places the cup back into the mold plate and moves it to the transfer mechanism. The second extraction device removes the sealed cup from the mold plate, and the transfer device pushes the second extraction device and the cup together to an external conveyor belt. The second extraction device places the cup on the conveyor belt, and the finished product is transported to the dispensing port by the conveyor belt. Users can then take the finished product from the dispensing port for consumption. This automatic filling machine has a compact structure and realizes full automation of the process from cup dropping to multi-powder ratio, water addition, stirring, sealing, coding, and transfer, reducing manual intervention.

[0042] For example, see Figure 1 , Figure 3 and Figure 4As shown, the cup storage compartment 21 is suspended directly above the corresponding mold plate 13 via the first mounting bracket 23. It includes a tube seat 212 mounted on the top of the first mounting bracket 23 via a transition plate 211 and a cup storage tube 214 mounted on the tube seat 212 via a fixing ring 213. The cup dropping device 22 includes a cup-rubbing frame that slides horizontally via a cup-rubbing cylinder 221 and a cup dropping plate. The cup-rubbing frame includes two cup-rubbing plates 222 connected to the push plate of the cup-rubbing cylinder 221 via a first connecting plate 225. The ends of the two cup-rubbing plates facing away from the first connecting plate are connected by a connecting strip to improve the overall strength of the cup-rubbing frame. The inner wall of the cup-rubbing plate 222 has a receiving boss and a cup-rubbing boss protruding from it. The cup-rubbing platform and the cup-rubbing protrusion are horizontally staggered and vertically spaced. The cup-dropping plate slides up and down between the two cup-rubbing plates 222. The cup-dropping plate 223 is located below the cup-rubbing protrusion, and its end near the cup storage compartment 21 is provided with a U-shaped groove. The inner wall of the U-shaped groove is provided with a cup-dropping slot that mates with the receiving protrusion. The top of the cup-dropping plate 223 is slidably connected to the first connecting plate through the cup-dropping cylinder 224. The end of the cup-rubbing protrusion near the receiving protrusion is provided with a guide slope. The bottom surface of the cup-rubbing protrusion is provided with a clearance groove corresponding to the cup-dropping plate 223. The bottom of the cup storage tube 215 extends to the bottom of the cup-rubbing frame, and its two sides are respectively recessed with opening slots corresponding to the receiving protrusion and the U-shaped groove.

[0043] In this technical solution, the first mounting bracket is assembled from conventional plates and fixed to the top surface of the workbench with conventional bolts. It suspends the cup storage compartment and cup dropping device above the corresponding mold plate. The top of the first mounting bracket has a first channel to accommodate the passage of the cup. The transition plate is a conventional plate structure, fixed to the top of the first mounting bracket with bolts, and contains a second channel coaxial with the first channel to accommodate the passage of the cup. The tube seat is an annular structure, coaxial with both the first and second channels, and a fixing ring is provided. Located on the outer wall of the cup compartment tube and fixed with bolts, it controls the installation depth of the cup compartment tube. The fixing ring rests on the top of the tube base. The portion of the cup compartment tube below the fixing ring passes through the tube base, transition plate, and mounting plate sequentially, extending to the bottom of the cup-rubbing holder. The portion of the cup compartment tube between the mounting plate and the cup-rubbing holder serves as a limit and guide for the cup's descent. An opening groove exposes the corresponding sides of the cup, allowing the rim of the bottom cup to rest on the receiving protrusion. Under its own weight, the cup inside the cup compartment tube falls along the tube, with the bottom cup... The rim (flanged edge of the cup mouth) rests on the receiving boss. When one of the mold plates on the conveyor chain moves directly below the cup storage compartment, the cup dropping device is activated. The piston rod of the cup-rubbing cylinder extends, causing the cup-rubbing frame and the cup dropping plate to move horizontally together. The cup dropping slot of the cup dropping plate engages with the rim of the bottom cup. The rim of the cup above the bottom cup slides to the top surface of the cup-rubbing boss. The piston rod of the cup dropping cylinder extends, pushing the cup engaged in the cup dropping slot onto the mold plate. The piston rod of the cup-rubbing cylinder retracts and resets, and the cup falling into the mold plate is limited by the recess of the mold plate. The cup body detaches from the cup-dropping plate, and the cup rim on the top surface of the cup-rubbing boss slides to the top surface of the receiving boss, becoming the new bottom cup body. The conveyor chain operates, moving the next mold plate directly below the cup storage device. At the same time, the piston rod of the cup-dropping cylinder retracts, the cup-dropping plate resets, and then the piston rod of the cup-rubbing cylinder extends, driving the cup-rubbing frame and the cup-dropping plate to move horizontally together. The cup-dropping slot of the cup-dropping plate engages with the rim of the new bottom cup body. Once the conveyor chain is in position, the next cup-dropping cycle can begin, reducing the waiting time of the conveyor chain and improving work efficiency.

[0044] For example, see Figure 1 and Figure 5 As shown, the feeding device includes a powder bin suspended above the conveyor chain 1 via a second mounting bracket 31. The powder bin includes a bin body mounting base 32 disposed on the second mounting bracket 31 and a bin body 33 inserted into the bin body mounting base 32. The bin body 33 is a cylindrical structure with an open top and a bin cover at its open end. A discharge port is provided on the bottom wall of the bin body 33 near the corresponding cup. The bin body mounting base 32 is provided with a notch corresponding to the discharge port. A turntable 34 is provided inside the bin body 33. Several dropping ports corresponding to the discharge port are provided inside the turntable 34. A feeding motor 35 for driving the turntable 34 is provided inside the second mounting bracket 31.

[0045] In this technical solution, the second mounting bracket is assembled from conventional sheet metal, sufficient to accommodate the installation of the feeding motor and powder hopper. The outlets of the two powder hoppers, positioned opposite each other on either side of the conveyor chain, are located within the opening of the same cup body. When filling the same type of powder, both hoppers can feed simultaneously, improving filling efficiency. When filling different powders, they are filled sequentially, i.e., one hopper completes feeding before the other begins. During the feeding process, a weighing mechanism monitors the filling volume. Ten feeding devices can fill ten or more different powders, meeting the ingredient requirements of nutritional powders. The second mounting bracket includes a motor mounting plate and mounting strips on both sides of the top of the motor mounting plate. The hopper mounting base is fixed to the top of the two mounting strips using conventional bolts. The synchronous belt between the machine and the drive shaft is set between two mounting strips. The bottom surface of the motor mounting plate is equipped with an adjustment block, and the adjustment block is connected to an adjustment screw that abuts against the drive motor, thereby adjusting the installation position of the feeding motor and thus adjusting the tension of the synchronous belt. The side of the motor mounting plate near the conveyor chain is mounted to the side of the conveyor chain through a conventional L-shaped bracket and a vertical plate, thereby suspending the powder hopper above the conveyor chain. The side of the second mounting bracket away from the powder hopper and the end of the mounting strip near the powder hopper are respectively connected to a cover to avoid pinching accidents. When the mold plate moves to below the discharge port, the feeding motor drives the turntable to rotate. When the discharge port in the turntable coincides with the discharge port of the hopper, the powder falls into the cup. After the feeding is completed, the turntable stops rotating, and the discharge port and discharge port are misaligned.

[0046] For example, see Figures 5 to 12 As shown, a rotating drive shaft 36 is installed inside the silo mounting base 32. One end of the drive shaft 36 is connected to the output shaft of the feeding motor 35 via a synchronous belt, and the other end drives the turntable 34 via a drive gear 37. A first drive post protrudes from the center of the bottom end of the drive gear 37 and is inserted into the drive shaft 36. A second drive post protrudes from the center of the top end of the drive gear 37 and penetrates the bottom wall of the silo body 33. The turntable 34 is fitted and engaged with the second drive post. A reverse-threaded stud protrudes from the top end of the second drive post and is connected to an agitator 38. Several guide plates are provided at the bottom of the agitator 38. The top of the stirring blade 38 is provided with scraper blades on both sides. The top surface of the turntable 34 has a material groove corresponding to the material discharge port. A material-pushing blade is provided between the stirring blade 38 and the turntable 34. The outer end of the material-pushing blade 39 is stuck in the inner wall of the hopper 33, and its bottom surface is provided with a flexible scraper corresponding to the material groove. The discharge port is provided with a discharge gear 320 through the mounting cylinder 310. The discharge gear 320 is a hollow structure with open ends and meshes with the drive gear 37. The mounting cylinder 310 is provided with a scraper rod. The bottom end of the scraper rod is bent and extends into the discharge gear 320.

[0047] In this technical solution, the synchronous belt and its pulley are existing structures and will not be described in detail here. The feeding motor is a stepper motor with a reducer, which drives the drive shaft to rotate via the synchronous belt, thereby driving the turntable to rotate. The bottom center of the bin mounting base has a thickened boss to ensure sufficient space for machining stepped holes. Bearing assemblies are installed in the stepped holes through bearing covers, etc. Conventional sealing rings are also installed between the bearing covers and the bearing assemblies. The inner ring at the bottom of the bearing assembly abuts against the corresponding synchronous pulley through conventional spacers, separating the synchronous pulley from the thickened boss of the mounting base to avoid wear on the mounting base. The top surface of the bin mounting base has three recessed insertion slots, and the bottom surface of the bin has protruding insertion feet corresponding to the insertion slots. The insertion feet and insertion slots cooperate to realize bin rotation. The container body and its mounting base are inserted and removed, forming a space between them to accommodate the drive gear. The top surface of the mounting base has a first annular protrusion with a notch penetrating it. The bottom surface of the container body has a second annular protrusion. The outer wall of the second protrusion slides into the inner wall of the first protrusion and is fixed using conventional set screws, improving the fixing strength of the container body and its mounting base. The first protrusion has a conventional positioning groove, and the outer wall of the second protrusion has a positioning protrusion corresponding to the positioning groove, facilitating rapid positioning of the container body. The top surface of the drive shaft has a cross-shaped first drive groove, and the center of the bottom surface of the drive gear has a cross-shaped first drive post that inserts into the first drive groove, thereby driving the drive gear to rotate via the drive shaft. The first drive post is inserted into the first drive... After removing the slots, set screws, etc., the chamber body, along with the drive gear, can be pulled out of the chamber body mounting base as a whole, facilitating chamber body replacement and maintenance. A second drive post protrudes from the top of the drive gear, penetrating the chamber body. The bottom wall of the chamber body has a through hole corresponding to the second drive post. To ensure the strength around the through hole, the bottom wall of the chamber body is thickened along the periphery of the through hole towards the inside of the chamber body. The portion of the second drive post protruding from the bottom wall of the chamber body is machined into a cross-shaped structure. The second drive slot is a cross-shaped slot structure corresponding to the second drive post, thereby driving the turntable to rotate via the drive gear. To ensure the strength of the turntable center and increase the contact area between the second drive slot and the second drive post, a thickened boss protrudes upward from the center of the turntable, through which the second drive slot passes. A nut corresponding to a reverse-threaded stud is embedded within the stirring blade. This is connected to the drive gear and rotates with it, stirring the powder in the hopper. Simultaneously, several radially staggered V-shaped guide vanes push the powder towards the periphery of the discharge port, allowing it to enter the trough and ensuring sufficient powder at the discharge port, thus improving feeding efficiency. Scrapers remove powder adhering to the inner wall of the hopper. A material-pushing vane, with one end near the center of the turntable fitted onto the thickened protrusion of the turntable and the other end near the periphery locked against the inner wall of the hopper, is fixed relative to the hopper. When the turntable rotates, a flexible scraper sweeps along the trough, pushing the powder to the next discharge port. Simultaneously, the material-pushing vane is positioned above the discharge port aligned with the discharge port, ensuring a fixed amount of powder can fall through each discharge port (within the allowable feeding error range).The flexible scraper is set radially along the turntable and the discharge gear, meaning its length spans the width of the corresponding trough. A pressure relief groove is located in the middle of the flexible scraper to prevent powder from being compressed into lumps. A scraper bar protrudes downwards from the side of the scraper facing away from the turntable's rotation direction and slides against the top surface of the turntable. The scraper bar is spaced apart from the trough along its length to avoid interfering with the turntable's rotation. The scraper bar scrapes the powder on the top surface of the turntable. A buffer groove corresponding to the trough is located on the bottom surface of the scraper. The opening direction of the buffer groove is consistent with the turntable's rotation direction. Powder flows from the opening of the buffer groove into the empty trough, preventing clumping caused by collapsing material. The bottom of the silo has arc-shaped protrusions on both sides of the discharge port. The inner wall of each arc-shaped protrusion has a conventional snap-fit ​​groove. The outer wall of the mounting cylinder has snap-fit ​​protrusions corresponding to the snap-fit ​​grooves. The discharge gear is a hollow structure with openings at both ends. Powder falls from the discharge gear. The top of the discharge gear has an annular protrusion that inserts into the discharge port, and the bottom has an annular protrusion that inserts into the mounting cylinder. This, along with the mounting cylinder, axially confines the discharge gear at the discharge port. The scraper rod has a U-shaped structure, with one end embedded in the mounting cylinder and the other end located inside the discharge gear. When the discharge gear rotates, the scraper rod scrapes off the powder adhering to the inner wall of the discharge gear.

[0048] For example, see Figure 1 and Figure 13 As shown, the weighing mechanism 9 includes a weighing electric cylinder 92 vertically mounted via a third mounting bracket 91 and a weighing bracket 93 connected to the weighing electric cylinder 92. The weighing bracket 93 is located below the upper mold plate 13 and is provided with one or two weighing trays 94 corresponding to the cup body.

[0049] In this technical solution, the third mounting bracket is assembled from conventional plates and other materials, which is sufficient to accommodate the installation of the weighing electric cylinder. The weighing bracket is inserted into the middle of the conveyor chain, that is, the weighing tray is directly below the corresponding mold plate on the upper layer. The number of weighing mechanisms depends on the number of feeding devices, ensuring that each feeding device corresponds to one weighing tray. Before the feeding device feeds the material, the weighing electric cylinder drives the weighing tray through the weighing bracket to push the cup upward, avoiding the concave platform of the mold plate from affecting the weighing. The weighing tray is set on the weighing bracket through a weighing sensor. The specific structure and principle are existing technologies and will not be described in detail here. The weighing tray feeds back the total weight data of the cup to the control device in real time, thereby monitoring the weight of the filled powder.

[0050] For example, see Figure 1 , Figure 14 and Figure 15As shown, the water injection device 41 includes a water injection needle 411 connected to a water storage tank (not shown) via a water injection pipe (not shown) and a metering pump (not shown). The water injection needle 411 is mounted on one side of the conveyor chain 1 via a water injection cylinder 412. The stirring device 42 includes a stirring shaft 421, a stirring motor 422 that drives the stirring shaft 421 to rotate, and a stirring electric cylinder 423 that drives the stirring shaft 421 to lift. A conventional stirring plate is connected to the end of the stirring shaft to improve the stirring effect. The stirring electric cylinder 423 is vertically mounted on the top of the workbench via a fourth mounting bracket 424. The water injection needle 411 and the stirring shaft 421 are vertically mounted within the cup opening of the same material cup. A liquid receiving tray 43 is mounted on the side of the conveyor chain 1 away from the stirring electric cylinder 423 via a liquid receiving cylinder 431. A drain pipe 432 is mounted on the side of the liquid receiving tray 43 away from the conveyor chain and is connected to an external collection tank, etc., for draining the liquid in the liquid receiving tray.

[0051] In this technical solution, when the cup containing the powder moves below the water injection needle and the stirring shaft, the piston rod of the liquid receiving cylinder retracts, causing the liquid receiving tray to move to the outer side of the conveyor chain, clearing the position between the cup opening and the water injection needle and stirring shaft, thus avoiding interference with the downward movement of the water injection needle and stirring shaft. Then, the water injection cylinder moves the water injection needle downward, and the metering pump adds a measured amount of water from the storage tank into the cup. The stirring electric cylinder moves the stirring shaft down into the cup. The stirring shaft and water injection needle are staggered to prevent interference. The stirring motor drives the stirring shaft to rotate, mixing the water and powder evenly. The stirring motor stops rotating, and the water injection cylinder moves the water injection needle upward (or it can rise after water addition is complete). The stirring electric cylinder then moves the stirring shaft... The liquid rises and leaves the cup. The piston rod of the liquid receiving cylinder extends, and the liquid receiving tray moves between the conveyor chain, the water injection needle, and the stirring shaft to prevent residual liquid on the injection needle and stirring shaft from dripping. The conveyor chain drives the stirred cup to the subsequent packaging and other work stations. The next cup containing powder moves to below the water injection needle and stirring shaft, and the above actions are repeated, repeating the water addition and stirring actions. The water in the storage tank is sterile water that has undergone sterilization and other treatments to avoid contamination / destruction of the nutrient powder components by bacteria in the water. In addition, the water in the storage tank can also maintain a certain temperature through conventional heat preservation measures to avoid the problem of high temperature damage to the nutrient powder components caused by boiling water. The metering pump is an existing device to realize quantitative water addition.

[0052] For example, see Figure 1 , Figure 16 and Figure 17 As shown, the film storage tank 51 is suspended directly above the corresponding mold plate 13 by the fifth mounting bracket 53, and the film picking device 52 includes a flipping film picking device driven by the lifting cylinder 521.

[0053] In this technical solution, the fifth mounting bracket includes a mounting side plate fixed to the side of the conveyor chain by conventional bolts, a horizontal plate mounted on the top of the mounting side plate, and a top plate suspended above the conveyor chain by two support plates. The film storage bin is columnar in shape, and the film storage bin has a sealing film storage hole with the same shape as the sealing film along its axis. The film storage bin is mounted on the top of the top plate by a film storage ring 511. The top plate has a material drop hole corresponding to the sealing film storage hole, and the bottom of the material drop hole is provided with several film-blocking soft rubber pads to prevent... The sealing film falls directly into the sealing film storage hole. The lifting cylinder is fixed to the side of the mounting side plate, and its piston rod is connected to a bearing seat 523 via a floating joint 522. The bearing seat slides between the two support plates. The flipping film-retrieving device includes a base plate 524 set at the top of the horizontal plate, a back plate 525 perpendicular to the top of the base plate, a rotating shaft 526, a film-suction rotating body 527, a film-suction rotating column 528, and a suction nozzle connected to the rotating shaft perpendicularly. The rotating shaft is a hollow tubular structure. The film-suction rotating body is transported by conventional means. The mounting blocks are equipped with connectors that connect to the rotating shaft and to a conventional vacuum generator. The rotating shaft rotates through the bearing seat and connects to the film suction rotating body. The back plate has a clearance groove corresponding to the rotating shaft. The film suction rotating body 527 has symmetrically arranged guide grooves with upward openings. Multiple film suction rotating columns that cooperate with the guide grooves are installed on the back plate. Limiting columns corresponding to the film suction rotating body are also set at the upper and lower ends of the back plate. The rotating shaft is equipped with a suction nozzle through a conventional pipe. An optical shaft is set between the bottom plate and the top plate to limit the movement direction of the bearing seat. When film needs to be removed, the lifting cylinder drives the rotating shaft and the film suction rotating body to move upward through the floating connector and the bearing seat. The guide groove of the film suction rotating body cooperates with the film suction rotating column, causing the film suction rotating body to rotate, thereby driving the rotating shaft to rotate around the bearing seat until the suction nozzle sucks up the sealing film at the bottom of the film storage bin. The lifting cylinder drives the rotating shaft and the film suction rotating body to reset. The sealing film sucked by the suction nozzle is exactly located on the concave platform of the corresponding mold plate. The vacuum generator stops working, and the sealing film stays at the top of the cup.

[0054] For example, see Figure 1 as well as Figure 18 To the diagram Figure 20As shown, the heat sealing device 61 is suspended above the corresponding mold plate 13 via the sixth mounting bracket 62. A heat sealing cylinder 63 is mounted at the top of the sixth mounting bracket 62. The piston rod of the heat sealing cylinder 63 is connected to the heat sealing device 61 via a connector 64, a guide plate 65, and a heat insulation device 66. The guide plate 65 is connected to the sixth mounting bracket 62 via several guide rods 651. The heat sealing device 61 includes a heat sealing head 611, a heating block 612, a transition block 613, and a mounting block 614 arranged sequentially from top to bottom. Several heating tubes 615 are installed inside the heating block 612. Several equal-height screws 616 connected to the transition block 613 are installed inside the mounting block 614. Springs 617 are respectively fitted on the outer wall of 616. The two ends of the springs 617 abut against the mounting block 614 and the transition block 613 respectively. The heat insulation device 66 includes a heat insulation plate 661, a connecting plate 662 and a heat dissipation column 663 arranged sequentially from top to bottom. The heat insulation plate 661 is attached to the bottom surface of the guide plate 65. The heat dissipation column 663 is connected to the top of the mounting block 614. A support frame 67 is arranged directly below the heat sealing device 61. The support frame 67 includes a support base plate 672 supported by side plates 671 at both ends and support side plates 673 vertically arranged at the top of the support base plate 672. The two support side plates 673 are spaced apart and form a channel to accommodate the cup body.

[0055] In this technical solution, the heat-sealing head, heating block, transition block, and mounting block are all disc-shaped structures. The heat-sealing head has a countersunk hole at its center on the bottom surface and is connected to the bottom surface of the heating block using conventional bolts. To improve the stability of the connection between the heat-sealing head and the heating block, a corresponding limiting groove is recessed on the bottom surface of the heating block, meaning the top of the heat-sealing head is embedded in the heating block. The side of the heating block is machined with mounting holes for installing the heating tube and monitoring holes for placing a temperature sensor. The transition plate prevents interference between the leveling bolts and the heating tube; that is, the threaded holes in the heating plate avoid the mounting holes of the heating tube. The connecting bolts between the transition plate and the heating plate pass through the top surface of the transition plate and connect to the threaded holes in the heating plate. To facilitate quick positioning of the transition plate and heating plate, a positioning boss protrudes from the top of the heating plate and embeds into the transition plate. During the downward pressing of the heat sealing device, the heat sealing head floats due to the springs fitted on the equal-height bolts, allowing it to completely conform to the cup mouth and sealing film, thus completely sealing the cup mouth. The heat sealing head contacts the sealing film at the cup rim through the heat sealing boss, completing the heat sealing. Simultaneously, it reduces contact with the sealing film in areas that do not require heat sealing, preventing deformation of the sealing film. (Guide shaft and straight...) The bearing restricts the movement direction of the guide plate, thus limiting the movement direction of the heat sealing device and improving movement accuracy. One end of the heat dissipation column is fixed to the bottom surface of the connecting plate with bolts, etc. The connecting plate and the heat insulation plate are fixed to the bottom surface of the guide plate with conventional bolts, etc. The other end of the heat dissipation column is connected to the top of the mounting block with bolts, etc., thereby separating the heat sealing device and the guide plate. The heat dissipation column separates the mounting block and the connecting plate and increases the contact area with air, improving the heat insulation and heat dissipation effect. The heat insulation plate is made of conventional heat insulation materials to further improve the heat insulation effect; adjustment Block 674 is fixed to the inner wall of the side plate (near the other side plate) by conventional bolts. The installation height of the supporting side plate can be adjusted by adjusting the installation height of the corresponding end of the supporting base plate by adjusting bolt 675. Supporting strips 676 are respectively provided at the top of the supporting side plate. Guide surfaces are provided on both sides of the top of the supporting strips 676. The supporting strips are made of materials with good self-lubricating properties such as nylon and can slide against the bottom surface of the mold plate. The guide surfaces guide the corresponding mold plate to slide to the top surface of the supporting strip, so as to prevent the end of the top surface of the supporting strip from getting stuck in the gap between adjacent mold plates.

[0056] For example, see Figure 1 , Figure 21 and Figure 22 As shown, the first cup-lifting device 71 includes a first cup-lifting cylinder 712 that drives the first suction cup 711 to rise and fall.

[0057] In this technical solution, the first cup-lifting cylinder is set on the side of the conveyor chain via a conventional cylinder mounting plate, etc. The first suction cup is a conventional suction cup or nozzle and is connected to an external vacuum generator. The first suction cup is connected to the push plate of the first cup-lifting cylinder via a second connecting plate. The top of the second connecting plate is connected to a connector for connecting to the vacuum generator. The first suction cup includes four nozzles set on the bottom surface of the second connecting plate via a sealing plate 713. The top surface of the sealing plate is provided with an air cavity connected to the connector. All four nozzles are connected to the air cavity. A sealing groove is provided around the air cavity, and a sealing ring 714 is embedded therein. Conventional covers are provided on the corresponding sides of the second connecting plate and the push plate. The first suction cup is suspended directly above the corresponding mold plate. The first cup-lifting cylinder drives the first suction cup to rise and fall, thereby lifting the cup body from the mold plate, so that the coding gun can mark the relevant information of the product on the cup body. After the coding is completed, the first suction cup puts the cup body back into the mold plate.

[0058] For example, see Figure 1 , Figure 23 and Figure 24 The transplanting device 82 includes a transplanting electric cylinder 822 horizontally arranged via a seventh mounting bracket 821, and the second cup lifting device 81 includes a second cup lifting cylinder 811 disposed on the transplanting electric cylinder 822 and a second suction cup 812 connected to the second cup lifting cylinder 811.

[0059] In this technical solution, the second suction cup has the same structure as the first suction cup. The second cup lifting cylinder and the second suction cup take out the processed finished product from the mold plate, and place the finished product on the conveyor belt through the transfer electric cylinder. The finished product is then transported to the feeding port by the conveyor belt. Users can take the finished product from the feeding port and then eat it. The transfer mechanism is also equipped with conventional covers, tank chains and accordion protective covers, etc.

[0060] In summary, the automatic filling machine of the present invention has a compact structure, which realizes full automation of the process from cup dropping to multi-powder ratio, water addition, stirring, packaging, coding and transfer, reducing manual intervention.
