Description

Technical Field

[0002] Cigarette filter rods refer to cigarette filter tips. Filter rods are made of cigarette tow and filter rod forming paper, processed, rolled and cut. Because of their different manufacturing materials, they are divided into many categories, such as fiber filter rods. Plant fiber microporous particles are green and environmentally friendly materials. They are made of natural cellulose raw materials and have efficient water and oil absorption effects. The porous structure and large specific surface area give it a strong selective adsorption capacity, which can enhance the filtering function of the filter rod and also enhance the adsorption capacity. Plant fiber microporous particle composite filter rods also have excellent ability to absorb tar, nicotine, carbon monoxide and other substances. Generally speaking, it is not easy to be sucked out of cigarette filters. However, since the production process of the filter tip is to loosen the curled fiber bundle, a small amount of short fibers and fiber scraps will fall off during the molding process. These tiny short fibers may adhere to the cigarette filter rod and affect the product quality of the filter rod, and may also cause harm to the human body. Therefore, a suction test is required during processing. During this process, a clamping tool is required to clamp the filter rod and the test wire tube to facilitate subsequent stable test operations.

[0031] Working principle: When assembling and using, according to the test needs, the test suction line tube is clamped with the cooperation of the side clamping arm 310 and the auxiliary clamping plate 300. During operation, the side clamping arm 310 is moved with the cooperation of the side lever 311 to facilitate the placement of the line tube, and then the torsion spring 321 is used to assist in extruding and clamping it. Then, according to the test height and the height clamping needs of the suction equipment, the support inner column 330, the support inner cylinder 340 and the support outer cylinder 350 are assisted in telescopic expansion. After adjusting to the appropriate position, the relative positions of the support inner column 330, the support inner cylinder 340 and the support outer cylinder 350 are tightened and limited by the upper locking pin 341 and the lower locking pin 351 to facilitate subsequent stable test operations.
