Sheet tobacco pack loosening equipment and method thereof

Abstract

The invention provides sheet tobacco pack loosening equipment and a method, which realize high loosening rate with high efficiency under the premise of keeping lower processing strength. The sheet tobacco pack loosening equipment comprises a loosening cabinet for holding a tobacco pack, wherein a tobacco pack vibration device is arranged at the bottom of the loosening cabinet; the tobacco pack vibration device is an excitation belt conveyer which comprises a speed-adjusting belt and an excitation bed body arranged on the bottom surface of the speed-adjusting belt, the excitation bed body is mounted on a machine frame through an elastic support piece and driven by a vibration exciter to generate vibration and transmit the vibration force to the sheet tobacco pack on the speed-adjusting belt; a flexible mechanical loosening device is arranged at the discharge end of the excitation belt conveyer. The sheet tobacco pack loosening method comprises tobacco pack vibration loosening and subsequent flexible mechanical loosening. The invention has the advantages that loosening without slicing can be realized, material breakage is low, high temperature is not used during the loosening process, therefore, the fragrance of the sheet tobacco can be remained to the largest extent.

Description

technical field [0001] The invention relates to equipment for performing low-strength loosening treatment on laminar tobacco bales before rehydration in the production process of shredded tobacco, in particular to a loosening device for loosening laminar tobacco bales by vibration. [0002] The invention also relates to a method for realizing low-strength loosening of the laminar cigarette bale by using the above-mentioned device. Background technique [0003] Loosening the bale of laminar tobacco before regaining moisture is one of the main technological links in the production of silk. When loosening the laminar packs, on the premise of increasing the loosening rate, it is necessary to avoid the chipping as much as possible; at the same time, it is also necessary to avoid the loss of the aroma of the tobacco sheets due to changes in temperature. Existing methods for loosening laminar cigarette packs, such as slicing, microwave loosening or vacuum loosening and moisture re...

AI Technical Summary

Problems solved by technology

However, in this method, the lamina bale is placed in a vibrating box to be vibrated after unpacking, and the lamina bale is peeled off layer by layer during the vibration process to loosen the lamina bale. Obtain a satisfactory loosening rate of the tobacco sheet, which will affect the uniformity of the tobacco material's subsequent moisture regain, thereby affecting the processing efficiency of the entire tobacco processing process and increasing the tobacco processing cost
