Double-glue-sheath combined vacuum control type switching device for tobacco filter measurement

Abstract

The invention discloses a double-glue-sheath combined vacuum control type switching device for tobacco filter measurement. The device comprises a shell and a glue sheath, wherein a through hole in the vertical direction is formed in the center of the shell, and the glue sheath is arranged in the through hole; the glue sheath comprises an outer glue sheath and an inner glue sheath, upper and lower ends of the inner glue sheath are respectively arranged at upper and lower ends of the shell; the outer glue sheath is arranged on the lower section in the shell, and sleeved outside the lower section of the inner glue sheath; and an upper vent hole communicated with the inside and the outside is formed on a position of the peripheral wall of the shell above the outer glue sheath, and a lower vent hole communicated with the inside and the outside is formed on a position of the peripheral wall of the shell corresponding to the outer glue sheath. According to the device, the lower end face and upper part of the inner glue sheath can be retracted by adding the outer glue sheath structure, so that the tobacco filter in the inner glue sheath is completely coated; and the requirement for adapting to the tobacco filters with different lengths can be achieved by adjusting the position or length of the outer glue sheath, and the adjustment is extremely convenient; and sample feeding and discharging can be carried out conveniently by vacuum control.

Description

technical field [0001] The invention relates to a vacuum-controlled switching device with rubber sleeves for measuring tobacco filter rods, in particular to a combined vacuum-controlled switching device with double rubber sleeves for measuring tobacco filter rods. Background technique [0002] In the tobacco industry, filter rod measurement is an important link. When measuring the filter rod, it should meet the test condition requirements of the standard GB / T22838.5-2009, that is: "The filter rod should be completely covered in the tester, and the coating layer of the filter rod should not leak air." The traditional wrapping device used for tobacco filter rod measurement is mainly composed of a vacuum-controlled latex tube (that is, the rubber sleeve in the present invention) and a housing. Since the filter rod is required to be completely covered by the latex tube during the measurement process, the latex The tube must have a diameter in its natural state (inner diameter o...

AI Technical Summary

Problems solved by technology

The defect of this device is that the movable block can only be set at the outlet of the rubber sleeve, and cannot control the position of the tobacco filter rod in the rubber sleeve, that is, the tobacco filter rod cannot be positioned at any position in the rubber sleeve; The time-consuming and labor-intensive problem of the type stopper

2. Set a fixed stop inside the outlet of the rubber sleeve to adjust the position of the tobacco filter rod in the rubber sleeve, that is, the tobacco filter rod can be positioned at any position in the rubber sleeve, but due to the addition of a fixed stop, the test is completed It is necessary to add a new mechanism (such as adding a new mechanism that rotates the whole mechanism to realize the sample layout) during the rear sample layout. The disadvantage is that the structure is complex and the end face of the tobacco filter rod outlet may be damaged.
