Description

Technical Field

[0001] The utility model relates to a fully degradable starch straw forming extrusion die, belonging to the technical field of straws. Background Art

[0002] A straw, or drinking straw, is a cylindrical, hollow plastic product. Its main function is to drink beverages from cups. It is also used to suck the marrow of some cooked animal long bones. Its diameter is generally about 0.5 cm, but when used to drink yogurt, pearl milk tea and other drinks, thicker straws are used, some with a diameter of 1.2 cm. Some less common straws with extremely small diameters are used for drinking hot drinks.

[0003] A Chinese patent (publication number: CN 218906251 U2) discloses a plastic straw mold, comprising: an outer mold, a guide column is arranged inside the outer mold, and the two are clamped together to form an injection cavity; an anti-blocking mechanism, which comprises a connecting capillary provided on the guide column, a conical tube is fixedly connected to the connecting capillary, and an intercepting ring is provided on the conical tube;

[0004] The plastic straw mold provided by the utility model has the following characteristics: when the injection molding machine is reopened, uneven plastic waste is squeezed out along the guide column, and then when the scraper is held by hand to remove the plastic waste, the scraper will cut off the plastic waste along the interception ring to prevent the connecting capillary from being blocked, and the tapered tube will expand the size of the connecting capillary, and the larger diameter can further prevent the connecting capillary from being blocked, and during extrusion injection molding, the liquid plastic can rotate and mix along the threaded rail to reduce the possibility of cavities. However, the outer mold and guide column in the above-mentioned patent are an integrated design, and there is a lack of a mechanism for disassembling the outer mold and the guide column, which makes it inconvenient to clean the injection cavity, the retention cavity and the guide column. In actual use, after the straw raw material is injected and extruded, there will be residual straw raw material in the injection cavity and the retention cavity including the guide column. If these raw materials are not cleaned in time, they may affect the next use, and in the process of the straw raw material being extruded, due to the high temperature of the raw material, the raw material is prone to deformation during the extrusion process, thereby affecting the quality of the straw product.
