Description

Cigarette single gram weight weighing and detecting device

Technical Field

The utility model relates to the technical field of cigarette production equipment, in particular to a cigarette single-gram-weight weighing and detecting device.

Background

Along with the gradual improvement of the cigarette quality requirement in the tobacco industry in recent years, the single cigarette gram weight has the effect of playing a role in improving the cigarette quality, so the single cigarette gram weight is always the key point of the industrial quality research in the tobacco industry; however, because factors influencing the single gram weight of the cigarette are multiple and the relevance is complex, the cigarette gram weight can not be kept stable all the time, and the cigarette gram weight can be kept stable as much as possible in the conventional common cigarette gram weight control process mainly by various equipment fixing operation methods under the fixing operation; on the other hand, the method mainly depends on experienced workers to teach the occurring deviation in daily production, but the method is time-consuming and labor-consuming due to the fact that a plurality of devices, complex environments and a plurality of parameters are involved.

On the production line of the existing high-grade cigarettes, the cigarettes on the production line need to be accurately weighed, and then the error range of the produced cigarettes is calculated; in the single weighing of cigarette, all carry out random sampling on the production line before, then carry out solitary weighing to the cigarette gram weight of sample, but such mode need come random sampling alone, need weigh and make statistics of alone again, if discover behind the continuous more unqualified cigarette, the staff that feeds back to last tobacco and add control process adjusts again, so will lead to wasting time and energy, the accuracy of weighing is lower, and delay that still appears feedback time leads to the promotion of a cigarette defective rate.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims to provide a cigarette single gram weight weighing and detecting device, which can directly and independently weigh cigarettes on a cigarette production line, and avoids the problems of time and labor waste and low accuracy of the existing sampling detection.

The utility model solves the technical problems by the following technical means:

a single-gram-weight cigarette weighing and detecting device comprises a base, wherein one side of the base is fixedly connected with a supporting leg, the other side of the base is fixedly connected with a supporting rod and a lever base, a lever is rotatably connected onto the lever base, a pressure detecting mechanism is fixedly connected onto the supporting rod, a first pressing plate is fixedly connected onto one side, close to the base, of the pressure detecting mechanism, a spring group is fixedly connected onto one side, away from the pressure detecting mechanism, of the first pressing plate, a second pressing plate is fixedly connected onto one end, away from the first pressing plate, of the spring group, a pressure rod is fixedly connected onto one end of the lever, and one end, away from the lever, of the pressure rod is in sliding and abutting contact with the second pressing plate; one side of the lever far away from the pressure rod is provided with an arc cigarette receiving disc.

Further, a pressure sensor is arranged in the pressure detection mechanism, the pressure sensor is in communication connection with a computer host, and the computer host is in communication connection with a tobacco controller. When the pressure sensor measures the maximum pressure of the cigarettes on the cigarettes after the cigarettes pass through the lever, the data are transmitted to the computer host, the software for analyzing the weight of the cigarettes is installed in the computer host, the pressure value can be calculated and compared with a standard value, and if the mass of a plurality of cigarettes is continuously found to be larger than an error acceptance range, the computer host transmits information to the control tobacco controller to adjust the tobacco adding amount of the previous process, so that the aims of accurate control and timely feedback adjustment are fulfilled.

Further, the landing leg includes drum and branch, the one end of branch inserts the drum to with drum sliding connection, the other end and the base fixed connection of branch, set up the screw hole with the inner chamber intercommunication of drum on the drum, screw hole female connection has the screw rod, the one end that the screw rod is located the drum offsets with branch, the other end fixedly connected with swiveling wheel of screw rod, the base is kept away from one side fixedly connected with bubble spirit level of branch. Utilize the lever to weigh the weight of cigarette, need base and lever to be in a horizontal position, so can guarantee the accuracy nature of weighing, use branch that can stretch out and draw back to through the levelness of watching bubble spirit level adjustment base, it is very convenient.

Further, a cigarette slide is arranged below the cigarette flange and fixedly installed on one side, far away from the supporting rod, of the base. The cigarette slide can catch the cigarette that rolls from a cigarette flange, and the cigarette then through a cigarette slide landing on the base, and it is in disorder to avoid the cigarette to roll the back cigarette that falls, influences the continuation of cigarette and carries.

Further, the one end that the base was kept away from to the lever base is provided with U type groove, U type inslot fixedly connected with dead lever, fixed cover is equipped with antifriction bearing on the dead lever, seted up on the lever and rotated the hole, the lever utilizes to rotate hole fixed connection on antifriction bearing. Thus, the lever can swing easily and flexibly.

Furthermore, the distance between the circle center position of the rotating hole and the cigarette receiving disc is 5-8 times of the distance between the circle center position of the rotating hole and the pressure rod. Because the mass of a single cigarette is only 10-12 g generally, the direct weighing necessarily causes larger error, and the pressure of the single cigarette on the pressure detection mechanism can be amplified through the lever, so that the spring group is conveniently compressed, and a more accurate measurement value is obtained.

Furthermore, an acute angle theta between a tangent line of an arc surface of one end of the cigarette receiving disc, which is far away from the lever, and the lever is 10-20 degrees. When the angle is larger, the end part rake angle of the cigarette receiving disc is higher, and the cigarettes are not easy to roll off from the cigarette receiving disc after the cigarettes press the cigarette receiving disc under the action of gravity; if the angle is too small, the cigarettes possibly fall off from the cigarette receiving disc after the staying time of the cigarettes on the cigarette receiving disc is too short, and the accuracy of the pressure sensor for measuring the weight of the cigarettes is reduced; through a plurality of tests, the cigarette weight is measured most accurately when the angle theta is 10-20 degrees.

The utility model has the beneficial effects that:

1. the cigarette weighing and detecting device can continuously weigh and detect cigarettes without independent sampling weighing and detecting, and is quicker, more convenient and more accurate.

2. The pressure sensor of the utility model measures the maximum pressure to the cigarettes after the cigarettes pass through the lever, then transmits the data to the computer host, the computer host is internally provided with cigarette weight analysis software, can calculate the pressure value and compare the pressure value with a standard value, if the mass of a plurality of cigarettes is continuously found to be larger than the error acceptance range, the computer host transmits information to the control tobacco controller to adjust the tobacco adding amount of the last procedure, thereby achieving the purposes of accurate control and timely feedback adjustment.
