Description

Technical Field

[0001] The utility model relates to the technical field of straw processing, in particular to a degradable straw semi-finished product cutting mechanism. Background Art

[0002] A straw, or drinking straw in English, is a cylindrical, hollow plastic product. Its main function is to drink beverages from a cup, and it is also used to suck the marrow of some cooked animal long bones. Generally, the diameter is about 0.5 cm, but when used to suck 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. Production method: After the plastic is melted, it passes through an extrusion die, which is the so-called mouthpiece, and then the machine extrude the plastic like a syringe (this process is continuous, and there is a screw on the machine that will extrude at a certain speed). When the plastic is still softened, it is fed into the machine and directly formed. Later, it is cut by the machine to become the straws we see in sections;

[0003] For example, the patent with publication number CN220218652U discloses a paper straw cutting device. According to the moving direction of the paper straw, a front conveying device, a cutting device and a rear conveying device are sequentially arranged; the front conveying device includes a wheel support and two front and rear guide support wheels installed on the wheel support, and a front brush wheel assembly driven to rise and fall by a driving cylinder is arranged above the guide support wheel; the cutting device includes a turntable driven by a driving wheel, and also includes an upper slide rail with an upper slider and a lower slide rail with a lower slider, a slide rod is arranged between the upper slider and the lower slider, and a lifting slide is installed on the slide rod, the back of the lifting slide is eccentrically hinged to the turntable, a cutter motor is installed at the front of the lifting slide, and a knife disc is installed on its output shaft; the rear conveying device includes a guide seat with a strip window on the top, and a rear brush wheel assembly adjusted to rise and fall by an adjustment assembly is arranged above the guide seat. The paper straw cutting equipment of the utility model has a reasonable structural design, high cutting efficiency and good cutting effect.

[0004] but:

[0005] Most of the existing semi-finished straw cutting mechanisms are fixed structures. If straws of different lengths need to be produced during the processing, the cutting parts need to be disassembled and installed to the designated location before production can begin, which is quite troublesome.
