Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco equipment, in particular to a leaf moistening and humidifying system. Background Art
[0002] In the cigarette production process, the leaf moistening and feeding system is the main equipment in the tobacco shred production line. Its main purpose is to loosen and heat the tobacco leaves, humidify and feed them, make the tobacco shreds soft and loose, and enhance the toughness and resistance to breakage of the tobacco leaves.
[0003] At present, leaf moistening humidifiers are generally used to moisten tobacco leaves. When moistening tobacco leaves, the leaf moistening humidifier will spray steam on the tobacco leaves. Since the tobacco leaves to be moistened contain some small tobacco dust, these tobacco dusts are easy to gather into clumps after being sprayed with steam, which affects the moistening effect. In addition, some tobacco dusts will adhere to the leaf moistening humidifier, causing abnormal operation of the leaf moistening humidifier.
[0004] In view of the above problems, the inventor of the present invention finally obtained the present invention after a long period of research and practice. Utility Model Content
[0005] The utility model provides a leaf moistening and humidifying system, aiming to solve the problem that tobacco dust affects the leaf moistening effect and the stable operation of the leaf moistening and humidifying machine.
[0006] The technical solution adopted by the utility model is:
[0007] A leaf moistening humidification system is provided, comprising a leaf moistening humidifier 1 and a vibrating screen 2, wherein a coarse material discharge end of the vibrating screen 2 is connected to a feed end of the leaf moistening humidifier, and a powder discharge end of the vibrating screen 2 is connected to a discharge end of the leaf moistening humidifier 1.
[0008] Furthermore, the powder discharge end of the vibrating screen 2 is connected to the discharge end of the leaf moistening humidifier 1 through the conveying air duct 3.
[0009] Furthermore, a belt conveyor 5 is provided at the discharge end of the leaf moistening humidifier 1 , and the outlet of the conveying air duct 3 is located above the belt conveyor 5 .
[0010] Furthermore, the outlet of the conveying air duct 3 is connected to a material dropper 6 , the discharge port of the material dropper 6 is connected to a material discharge port 7 , and the material discharge port 7 is covered on the belt conveyor 5 .
[0011] Furthermore, a conveying fan 4 is installed in the middle of the conveying air duct 3 .
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] The utility model adds a vibrating screen at the front end of the leaf moistening humidifier to remove the tobacco dust from the tobacco before introducing the tobacco into the leaf moistening humidifier for moistening, effectively avoiding the influence of tobacco dust on the moistening effect of the tobacco and the influence on the stable operation of the leaf moistening humidifier. The screened tobacco dust is directly added to the moistened tobacco through the conveying air duct, thereby ensuring the integrity of various components in the moistened tobacco and guaranteeing the quality of the tobacco. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] In order to more clearly illustrate the specific implementation methods of the utility model or the technical solutions in the prior art, the drawings required for use in the specific implementation methods or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some implementation methods of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0015] Figure 1 A schematic structural diagram of a leaf moistening and humidifying system according to an embodiment of the utility model is shown. DETAILED DESCRIPTION
[0016] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.
[0017] The term "including" and its variations used in this article represent open inclusion, that is, "including but not limited to". Unless otherwise stated, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0018] The utility model provides a leaf moistening humidification system, comprising a leaf moistening humidifier 1 and a vibrating screen 2. The coarse material discharge end of the vibrating screen 2 is connected to the feed end of the leaf moistening humidifier 1, and the powder discharge end of the vibrating screen 2 is connected to the discharge end of the leaf moistening humidifier 1 through a conveying air duct 3.
[0019] During operation, the tobacco that needs to be moistened is first screened through the vibrating screen 2 to remove the fine tobacco segments and tobacco dust in the tobacco, and then is led out from the coarse material discharge end of the vibrating screen 2, directly introduced into the leaf moistening humidifier 1 for leaf moistening treatment, and finally is led out from the discharge end of the leaf moistening humidifier 1; the fine tobacco segments and tobacco dust screened out by the vibrating screen 2 directly bypass the leaf moistening humidifier 1 through the conveying air duct 3 and are mixed into the tobacco material with moisturized leaves, so as to avoid the problem that the fine tobacco segments and tobacco dust enter the leaf moistening humidifier 1, resulting in poor tobacco moistening effect and affecting the normal operation of the leaf moistening humidifier 1.
[0020] In some specific embodiments, a conveying fan 4 is provided on the conveying air duct 3. Specifically, the middle of the conveying air duct 3 is disconnected to obtain two joints, and the two joints are respectively connected to the conveying fan 4, so that the conveying fan 4 provides conveying power for the conveying air duct 3.
[0021] In some specific embodiments, a belt conveyor 5 is provided at the discharge port of the leaf moistening humidifier 1. The belt conveyor 5 is used to transport the moistened tobacco to the next process. The belt conveyor is provided with a discharge port 7, and the discharge port 7 is covered on the belt conveyor 5 so that the tobacco falling from the discharge port 7 can fall directly onto the belt conveyor 5. A dropper 6 is provided on the discharge port 7, and the outlet of the conveying air duct 3 is connected to the feed port of the dropper 6. The fine tobacco segments and tobacco dust transported through the conveying air duct 3 enter the discharge port 7 after passing through the dropper 6. Since the dropper 6 can separate the fine tobacco segments and tobacco dust from the wind, the fine tobacco segments and tobacco dust can be better added to the moistened tobacco.
[0022] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
