Description

Technical Field

[0001] The utility model relates to an automatic cutting machine for fully degradable starch straws, 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 a cup. It is also used to suck the marrow of some cooked animal long bones. The diameter is generally about 0.5 cm, but when used to suck yogurt, pearl milk tea and other drinks, a thicker straw is used, some with a diameter of 1.2 cm. Some less common straws with extremely small diameters are used to drink hot drinks.

[0003] A Chinese patent (publication number: CN 218365002 U) discloses a fully automatic straw cutting machine, including a carrying box, a conveying mechanism, a cutting mechanism, a length adjustment mechanism and a control mechanism; during operation, the straw material to be cut is inserted into the conveying space and the through hole, and the rotating motor drives the conveying wheel to rotate and the passive wheel drives the straw material to be cut to move. When the straw material to be cut abuts against the blocking plate, the pressure sensor senses the pressure, and the control mechanism controls the push cylinder to work, and the push cylinder drives the cutting knife to insert into the cutting port to cut the straw material to be cut by rotating the connecting rod and the knife seat. The screw motor drives the blocking plate to move away from the carrying seat, so that the cut straw falls. That is to say, the distance from the blocking plate to the cutting port is the length of the straw, and the screw motor adjusts the length of the cut straw by driving the blocking plate to move. The above-mentioned fully automatic straw cutting machine has high working efficiency and high precision.

[0004] The straws include fully degradable starch straws. In the production process of fully degradable starch straws, an automatic cutting machine is needed to cut the straw raw materials. The straws have beveled angles and flat angles. The two different cutting methods require two automatic cutting machines for cutting. The above patent cannot flexibly use the two cutting methods, which increases the production input cost. Moreover, before the straw raw materials are sent to the automatic cutting machine, since the straw raw materials have just been formed, the straw raw materials are still relatively soft and are prone to adhesion during the cutting process, which makes the cut straws unable to be used normally, affecting the quality of the straws.

[0005] Therefore, a fully degradable starch straw automatic cutting machine is proposed. Utility Model Content
