Overweight detection device for prepressing and packaging reconstituted tobacco leaves and method for detecting feed weight of material box by using overweight detection device for prepressing and packaging reconstituted tobacco leaves

Abstract

The invention provides an overweight detection device for prepressing and packaging reconstituted tobacco leaves, and a method for detecting the feed weight of a material box by using the overweight detection device for prepressing and packaging the reconstituted tobacco leaves. A weighing platform is fixed on a support through a plurality of lifting air cylinders; a conveying belt conveyor is fixed on the upper side of the weighing platform; a discharging pipeline is fixed on the upper side of the support; a bidirectional feeding belt conveyor is aligned with the discharging pipeline; one endof a positioning frame of a detection assembly is fixed to the side wall of the support; the other end of the positioning frame of the detection assembly is fixed to a non-contact displacement sensor; and a detection baffle plate is fixedly connected to the side wall of the weighing platform. The method comprises the steps that the material box moves to the lower side of the discharging pipeline;the lifting air cylinders are synchronously started, and the weighing platform is lifted; the bidirectional feeding belt conveyor is started, raw materials of the reconstituted tobacco leaves fall into the material box until the weight of the raw materials reaches a preset value, the bidirectional feeding belt conveyor stops running, and the weight of the raw materials of the reconstituted tobacco leaves in the material box is no longer increased; and the conveying belt conveyor conveys the material box to a subsequent station. The method has the advantages of being convenient to use, small in error rate and convenient for industrial production.

Description

technical field [0001] The invention relates to a device for detecting overweight of reconstituted tobacco leaves in pre-pressed packaging. [0002] The invention also relates to a detection method of a reconstituted tobacco leaf pre-pressed packaging overweight detection device. Background technique [0003] In the production process of reconstituted tobacco leaves in the tobacco industry, the finished reconstituted tobacco leaves are boxed and pre-pressed by a pre-pressing baler according to a certain weight, and then re-checked by a double scale. Carry out bundled transportation and storage. [0004] Due to the particularity of reconstituted tobacco leaf dust, it is unavoidable in actual production. The structure design of the original weighing detection device is unreasonable. It is installed at the bottom of the weighing platform and is easily affected by it. Misoperation or non-operation occurs, resulting in overweight and extrusion deformation. , Destroying the phot...

Problems solved by technology

[0004] Due to the particularity of reconstituted tobacco leaf dust, it is unavoidable in actual production. The structure design of the original weighing detection device is unreasonable. It is installed at the bottom of the weighing platform and is easily affected by it. Misoperation or non-operation occurs, resulting in overweight and extrusion deformation. , destroy the photocells on the track, the travel switch, the pressure head above the weighing platform, the moving material box and the carton positioner, etc., causing a series of equipment damage

The failure rate of pre-pressing balers is increasing year by year, seriously affecting normal production

In addition, the reduced accuracy and reliability of the weighing of reconstituted tobacco leaves will also affect the ratio of shredded tobacco after it enters the tobacco factory's silk production line and the accuracy of cigarette formula, resulting in fluctuations in the internal quality of cigarettes
