Technical Field

[0001] This utility model relates to the field of lunch box manufacturing technology, specifically to a continuous production molding machine for biodegradable lunch boxes. Background Technology

[0002] With economic development, the demand for food delivery is growing stronger. As the food delivery industry flourishes, the demand for disposable food containers is also increasing. Plastics have the characteristics of low toxicity, high melting point, strong plasticity, simple production and relatively low cost, making them the mainstream material for manufacturing disposable fast food containers.

[0003] A search revealed a patent document with publication number CN219748663U that discloses a disposable lunchbox forming device. This utility model relates to the field of lunchbox technology and includes a base. A lower mold is fixedly mounted on the top of the base. A circulating water channel is provided inside the side wall of the lower mold. A main inlet pipe and a main outlet pipe are fixedly mounted on the inlet and outlet of the circulating water channel. A cooling chamber is provided inside the bottom wall of the lower mold. Heat-conducting fins are fixedly mounted inside the cooling chamber. An inlet pipe and an outlet pipe are also provided inside the cooling chamber. A refrigeration unit is fixedly mounted on the top of the base. The advantages of this utility model are: after cooling by the refrigeration unit, the refrigerant is transported to the circulating water channel and cooling chamber through the main inlet pipe and the outlet pipe to cool the lower mold. Then, it flows back to the refrigeration unit through the outlet pipe and the main outlet pipe for continuous cooling. Even after prolonged operation, the refrigerant temperature will not rise, and the cooling effect remains at a consistent level, making it convenient to use.

[0004] The above technical solution uses an upper mold and a lower mold with protrusions that are consistent with the concave cavity of the lunch box to hot press and form the lunch box. However, this forming method makes the lunch boxes relatively independent. The disorderly unloading during the unloading process of the lunch boxes causes the lunch boxes to occupy a lot of space and become messy and unnecessary. At the same time, it is also easy for the lunch boxes to scratch each other, affecting the appearance.

[0005] Therefore, it is necessary to invent a biodegradable lunchbox continuous production molding machine to solve the above problems. Summary of the Invention

A conveying mechanism 205 is provided below the fixed plate 204 and installed inside the lunch box forming machine 1. The conveying mechanism 205 receives lunch boxes and discharges them. Several sets of material discharge grooves 206 are opened on the surface of the fixed plate 204. When the material discharge cylinder 201 is activated, it drives the material discharge plate 202 and the telescopic rod 207 to cooperate with the material discharge grooves 206 on the surface of the fixed plate 204, thereby ensuring that the lunch boxes are formed according to the material discharge grooves 206 on the surface of the fixed plate 204. The food container falls to a predetermined position. Several sets of telescopic rods 207 are fixedly connected to the bottom end of the feeding plate 202, and the telescopic rods 207 are located inside the grooved blade 203. A top contact block 208 is fixedly connected to the bottom end of the telescopic rod 207. A return spring 209 is sleeved on the outer wall of the telescopic rod 207. The cooperation of the telescopic rods 207 and other parts prevents the food container from getting stuck inside the telescopic rods 207. Through the cooperation of the food container forming machine 1 and the automatic feeding machine 2, when the food container reaches below the feeding cylinder 201... The starting cylinder 201 drives the dropping plate 202 and the grooved blade 203 to descend. The grooved blade 203 and the fixing plate 204 work together to cut the lunch box from the inside of the grooved blade 203. At the same time, the telescopic rod 207, the top contact block 208 and the return spring 209 work together to push the lunch box out. The cutting sheet is then dropped by the dropping groove 206, so that the lunch box lands on the surface of the conveying mechanism 205. The conveying mechanism 205 then transports the stacked lunch boxes out.

[0026] Refer to the instruction manual appendix Figure 1-5The top of the lunchbox forming machine 1 is fixedly connected to an upper forming cylinder 3. The output end of the upper forming cylinder 3 is fixedly connected to an upper mold 4. A lower forming cylinder 5 is located below the upper mold 4 and is fixedly connected to the bottom wall of the lunchbox forming machine 1. The output end of the lower forming cylinder 5 is fixedly connected to a lower mold 6. Activating the upper forming cylinder 3 and the lower forming cylinder 5 causes the upper mold 4 and the lower mold 6 to close. Two sets of sliding tables 8 are fixedly connected to the inner wall of the lunchbox forming machine 1. Several sets of pressing rings 7 are fixedly connected to the top of the sliding tables 8. A pressing roller 10 is located on the side of the lunchbox forming machine 1 away from the lower forming cylinder 5.

A water outlet pipe 15 is fixedly connected to the bottom end of the circulation pump 14. The water outlet pipe 15 is fixedly connected to the bottom end of the lower mold 6. The cooling of the lower mold 6 is achieved by the cooperation of the water outlet hose 11, the cold water tank 12 and other parts to improve the shaping effect. The upper forming cylinder 3, the upper mold 4, the lower forming cylinder 5 and other parts cooperate to move the upper mold 4 and the lower mold 6, thereby achieving mold closing. After mold closing, the mold is reset so that the formed lunch box and sheet can continue to move along the sliding table 8. The sheet is rotated by the rotation of the electric winding roller 9, thereby achieving continuous production. The cooperation of the electric winding roller 9 and the pressing roller 10 avoids the sheet from warping and affecting the material dropping.

[0027] The working principle of this practical application is as follows:

[0028] Refer to the instruction manual appendix Figure 1-5When producing biodegradable lunch boxes, the biodegradable material sheet is first placed between the pressing ring 7 and the sliding table 8, and then wound up using the electric winding roller 9. The upper forming cylinder 3 and the lower forming cylinder 5 are activated, and through their cooperation, the upper mold 4 and the lower mold 6 are moved, thus achieving mold closing. After mold closing, the mold is reset, allowing the formed lunch box and sheet to continue moving along the sliding table 8. The rotation of the electric winding roller 9 drives the sheet to rotate, allowing the lunch box and sheet to move together. Upon reaching the bottom of the unloading cylinder 201, the unloading cylinder 201 is activated, causing the unloading plate 202 and the grooved blade 203 to descend. The grooved blade 203 and the fixed plate 204 work together to cut the lunch box from the inside of the grooved blade 203. At the same time, the telescopic rod 207, the top contact block 208 and the return spring 209 work together to push the lunch box out. The unloading groove 206 is used to make the cut sheet fall down, so that the lunch box lands on the surface of the conveying mechanism 205. The conveying mechanism 205 is then used to transport the stacked lunch boxes out.

[0029] When the upper mold 4 and the lower mold 6 are closed, cooling water is injected into the cold water tank 12 through the water outlet hose 11, and at the same time, the cooling water is sent into the lower mold 6 through the circulation pump 14 and the water outlet pipe 15 to promote mold closing. Finally, the cooling water is circulated through the water inlet hose 13, thereby improving the mold closing efficiency.
