[0002] Degradable food cups are a type of food packaging equipment made of flour or corn starch, and are mainly used for packaging bulk ready-to-eat foods, such as porridge and milk. Consumers can directly use the food cups and the food they contain together, which brings convenience to consumers and users, and correspondingly reduces the pollution caused to the environment by non-degradable packaging cup materials.

[0003] The current food cup production process typically involves first forming the pre-mixed dough (flour or corn starch, for example) into a paper cup using a forming machine. The semi-finished product is then sprayed with edible glue to set the shape before being dried in a drying oven. Finally, unqualified finished products are removed to complete the production process. The current production model relies on individual processes, one by one, across different equipment and workflows. This prevents automated assembly line production, resulting in low efficiency and high product costs. Therefore, a system that can fully automate the mass production of biodegradable food cups is crucial. Summary of the Invention

[0033] Figure 1-16 As shown, the present invention combines the existing mature control subsystem, automatic dough mixing and quantitative discharging mechanism, front gripping robot, noodle cup forming machine, rear gripping robot, semi-finished product gripping robot, finished product gripping robot, automatic assembly line drying mechanism technology (this application does not elaborate on the above technical solutions, nor does it protect the above solutions). The automatic dough mixing and quantitative discharging mechanism automatically completes the dough mixing and dough discharging to the quantitative receiving and discharging mechanism 7. When the quantitative receiving and discharging mechanism 7 is working, the X-slide module 73 of the first group of receiving trays 72 is started, and the first group of receiving trays 72 starts to receive materials and moves four times. After the multiple receiving troughs are full, the cylinder opening and closing mechanism 75 of the first group of receiving trays 72 is opened, and all the dough in the first group of receiving trays 72 falls into the multiple receiving troughs of the second group of receiving trays 72. The cylinder opening and closing mechanism 7 of the first group of receiving trays 72 is closed, and the first group of receiving trays 72 continues to receive materials. The X-slide module 73 of the first group of receiving trays 72 continues to reciprocate. At the same time, the second group of receiving trays 7 2, the X slide module 73 module is started and moved to above the second group of receiving trays 72, the cylinder opening and closing mechanism 75 of the second group of receiving trays 72 is opened, and the dough falls into the third group of receiving trays 72, and then the cylinder opening and closing mechanism 75 of the second group of receiving trays 72 is closed. At the same time, the Y slide module 73 of the third group of receiving trays 72 moves once, and the cycle is reciprocating. After the third group of receiving trays 72 are full of material, the dough in the third group of receiving trays 72 falls into the fourth group of receiving trays 72. After the subsequent front grasping robot 1 controls the forming robot's material tray to the lower end of the fourth group of receiving trays 72, the cylinder opening and closing mechanism 75 of the fourth group of receiving trays 72 is opened, and all the dough falls into the forming material tray.

[0034] Figure 1-16As shown, the front gripper robot 1 transfers the forming material tray to the noodle cup forming machine. The noodle cup forming machine can simultaneously process multiple doughs discharged by the quantitative receiving and discharging mechanism 7 into food cup blanks. Then, the rear gripper robot 2, after the robot's variable-pitch cup absorbing mechanism is activated, picks up 25 cups (food cup blanks) from the forming machine at a time. After completion, the variable-pitch cylinder robot changes its pitch and places the cups onto the circular conveyor line 6, placing them one row (5 cups) at a time, in five tracking cycles. The rear gripper robot 2 picks up 25 cups and places them onto the cup holder 62 of the circular conveyor line in five cycles. Afterward, the cups pass through the air bottle washing mechanism 8 and the rotary glue spraying mechanism 9. The air bottle washing mechanism 8 flushes all the cups with air to ensure their cleanliness. Then, the rotary spraying mechanism 9 evenly sprays the interior of the cups with food glue 9 (which increases in strength after drying). Then, the rear semi-finished product gripper robot 3 picks up 10 cups at a time and places them into the drying mechanism 5 of the rear automatic assembly line for drying. Specifically, the rotary glue spraying mechanism 9 operates by extending spring 96, pulling the cup-spinning wheel 91 close to the workstation base plate 63. The high-speed rotary motor 92 instantly activates, simultaneously gripping the cup from below and causing the glue gun to begin spraying glue. Once the glue is sprayed, the retraction cylinder 84 activates, retracting the rotating wheel 91. After the cups are dried, the robot's cup-gripping and rejection mechanism moves to the appropriate position, and the cup-gripping cylinder 46 activates, simultaneously gripping the cup and placing it on the stacking conveyor. For ungrabbed cups (those that are tilted and not vertical), the next time the cup is gripped, the air blower 47 activates and removes the cup (to prevent it from entering the stacking conveyor, which could cause it to malfunction). In the cup stacking and conveying mechanism, the robot cup gripping and rejecting mechanism places the cups into the cup tray 103, ten at a time. After it reaches the set height, the photoelectric switch 104 receives the signal, the cup pressing cylinder 107 starts to press down the cup, the flipping cylinder 102 starts working, and the cup starts to rotate. After it is in place, the cup pushing cylinder 105 starts working and pushes the cup to the subsequent pallet conveyor line (existing mature technology). The flipping cylinder 102 returns to its position, the pallet conveyor line starts conveying, and the rodless cylinder 107 pushes the cup to the rear pillow packaging machine (mature technology). At the same time, cups that do not meet the height standard (cups that fall down and are not vertical) fall into the rear rejection track, completing the entire production process. In the present application, the cup stacking and conveying mechanism uses air to remove cups that do not meet the height standard. Specifically, when the cups coming out of the drying mechanism are stacked, each cup and each workstation has a photoelectric switch. When the robot cup clamping and rejection mechanism grabs the corresponding paper cup and places it on the cup stacking and conveying mechanism, the corresponding photoelectric switch will detect it. If there is a workstation where there is no cup and it is not detected, it means that the previous cup coming out of the oven fell down and was not vertical. In this way, when the robot cup clamping and rejection mechanism returns to its position, it will blow away the fallen cup and clamp the next vertical cup to stack the cups.Through all of the above technical solutions, the present invention combines the existing mature technologies of the control subsystem, automatic dough mixing and quantitative discharging mechanism, front gripping robot, noodle cup forming machine, rear gripping robot, semi-finished product grasping robot, finished product grasping robot, and automatic assembly line drying mechanism. The automatic dough mixing and quantitative discharging mechanism can fully automatically complete dough discharging, the quantitative receiving and discharging mechanism can complete batch discharging, and the forming machine can complete the formation of dough into cup bodies. In conjunction with the circular conveyor line, the air bottle washing mechanism can blow out foreign matter from the cup body with compressed air, the rotary glue spraying mechanism can spray glue at any position inside or outside the cup body, the automatic assembly line drying mechanism can dry and shape the semi-finished products, the robotic cup gripping and rejecting mechanism can blow air to reject non-upright finished products to the waste station, and the cup stacking conveying mechanism can stack the finished products together and output them to the packaging station. Because the present invention realizes the automation of all processes, it improves work efficiency and correspondingly ensures product quality.
