Description
Technical Field
The invention belongs to the technical field of production of heating cigarette filter sticks, and particularly relates to a preparation method of a PLA hollow tube composite low-suction-resistance cooling filter stick.
Background
In the 80 s of the last century, international tobacco enterprises began to invest in developing novel cigarettes which are heated and not burnt, such as carbon heating, electric heating and the like, and in 2014, phenanthrene Mo Guoji was formally marketed in japan for heating and not burning electronic cigarettes IQOS, so that the global development of heating and not burning electronic cigarettes is driven.
The main components of the heated non-combustible cigarette smoke are an atomizing agent, water, tobacco volatile components and components which are cracked at low temperature. The amount of smoke during suction is directly related to the pressure drop and filtration efficiency of the filter rod. When the pressure drop is large and the filtering efficiency is high, the smoke is adsorbed by the filter stick, the smoke amount is small, and the experience and satisfaction of a user are poor; conversely, when the pressure drop is smaller and the filtering efficiency is lower, the smoke quantity is large, and the experience and satisfaction of the smoker are good.
The biggest quality problem when heating the non-burning cigarettes for smoking is that the temperature of the smoke is high and the hot stabbing feeling is strong. Reducing the flue gas temperature is a technological direction in which such products are continually improving.
The filter stick punches and introduces appropriate amount of sidestream air, can reduce flue gas temperature to a certain extent, but can dilute the flue gas when introducing the air volume too big, reduce the flue gas quality, consumer experience feel and satisfaction feel poor, just lean on punching technology can not satisfy the heating cigarette demand.
In recent years, researches and documents about flue gas cooling are more, but most of the used filter rods adopt three-section and more complex two-section or special structures, wherein document CN 108542003B describes a low-absorption-resistance polylactic acid filter rod and a preparation method thereof, the low-absorption-resistance polylactic acid filter rod is mainly prepared from high-denier polylactic acid tows, and the filter rod has the problem of being melted and contracted by hot flue gas when being directly used and is generally required to be used after being compounded with other filter rods. Document CN 111387546A, CN 212728776U describes a venturi hollow filter rod for heating cigarettes, a venturi cooling principle is adopted, document CN 111436650a describes a hollow cooling filter rod, a bellows cooling principle and a hollow tube shape are adopted, and the preparation of the filter rod is relatively complex and the cost is high. Document CN212260457U describes a filter rod comprising (bellows type) cavities, two ends of which are core rods, and is formed by ternary combination, and document CN 212574122U describes a hollow cooling composite filter rod comprising a functional section, a special-shaped hollow section and a cooling section, which is also of a ternary structure, and has relatively high complex production cost. Document CN213404844U describes a cavity-type heating cigarette with a multi-concave arc-shaped hollow filter rod, wherein the filter rod part structure is also very complex, and the problems of high production cost and inconvenient industrialized rolling and connection exist.
Principle of "venturi": as the gas flows inside the venturi, the dynamic pressure reaches a maximum and the static pressure reaches a minimum at the narrowest point of the pipe, and the velocity of the gas increases due to the reduced cross-sectional area of the through-flow. The entire current is subjected to the conduit deflation process at the same time, and the pressure is reduced at the same time. And thus creates a pressure differential that provides an external suction force to the fluid.
The venturi effect, also known as venturi effect. This effect is manifested in the phenomenon that when a restricted flow passes through a reduced flow cross-section, the flow velocity of the fluid increases, with the flow velocity being inversely proportional to the flow cross-section. Whereas an increase in flow rate is known from bernoulli's law to be accompanied by a decrease in fluid pressure, a common venturi phenomenon. This effect is colloquially referred to as creating a low pressure in the vicinity of the fluid flowing at high velocity, thereby creating an adsorption effect.
The PLA hollow tube composite filter stick provided by the invention has large airflow channels and low flow velocity at the hollow tube sections at the two ends; in the PLA cooling section in the middle, because of the existence of PLA silk bundle, the passageway of air current becomes thin, and the velocity of flow increases, will form the vacuum district around the filter tip stick is inside, if carry out laser drilling around this section filter tip stick, will form adsorption effect to the air around when sucking, is favorable to the cooling of flue gas and the increase of smog volume. However, when the smoke amount of the smoke generating section is too large and the temperature is too high, the PLA tow may be melted during the sucking process to block the smoke passage, so that the smoke amount of the second half part is reduced. In order to solve the problem, the invention performs laser drilling on the empty pipe section at the front end of the PLA cooling section, and introduces partial sidestream air in advance, so that the flue gas enters the PLA section for further filtration and cooling after being pre-cooled, thereby avoiding channel blockage and achieving better effect. The filter tip rod integrates a flow measurement air cooling technology, a Venturi cooling technology and a PLA cooling technology, has the characteristics of simple structure, simple processing technology, low production cost, good cooling effect and the like, and provides a good filter tip selection scheme for heating cigarettes.
Disclosure of Invention
The invention aims to solve the technical problem of providing a preparation method of a PLA hollow tube composite low-absorption-resistance cooling filter tip rod, which adopts a three-section structure and consists of a first hollow tube section, a PLA cooling filter section, a second hollow tube section and forming paper wrapped outside, wherein the forming paper wrapped outside the composite filter tip rod is high-permeability forming paper with the air permeability of 5500CU or more, the first hollow tube section is a hollow tube with the air permeability of 5500CU or more, or is a hollow tube with the air permeability of wall material of air impermeability or low air permeability, but after punching, the air permeability of a punching area is more than or equal to 300 CU. The second hollow tube section is arranged at the lip end of the cigarette, the second hollow tube section is contained in the mouth during smoking, laser drilling is not needed on the second hollow tube section, and whether the second hollow tube section is ventilated has little influence on the quality of the heated cigarette. This filter tip stick accessible binary complex or ternary complex preparation can directly be connected with the tobacco section of fuming and use, carries out laser drilling around the PLA cooling filter section in the centre, has venturi cooling effect when sucking, carries out laser drilling at first empty pipe section, introduces sidestream air and cools down in advance, can further strengthen cooling effect.
The hollowness of the first hollow pipe section and the second hollow pipe section is 15-85%, the suction resistance is increased when the porosity is lower than 15%, the smoke amount is reduced, and the preparation difficulty is greatly increased when the porosity is higher than 85%, so that the preparation is unnecessary. The materials of the first hollow pipe section and the second hollow pipe section comprise acetate fiber hollow pipes, paper pipes, or PE, PP, PET, PLA injection molding pipes of silica gel materials, or firmware with hollow structures formed by mixing and extruding plant materials, adhesives and functional additives; the plant material comprises tobacco powder, tea powder or starch, the adhesive comprises carrageenan, xanthan gum, gelatin, sodium alginate, CMC or konjac gum, and the functional additive comprises sugar, honey, sugar alcohol and essence.
When the PLA hollow tube composite filter tip rod is connected with a heated cigarette, on-line laser drilling is carried out on the first hollow tube section and/or the PLA cooling section, or off-line drilling is carried out on tipping paper at the corresponding position, wherein the tipping paper refers to tipping paper, label paper and the like.
The laser punching position is determined according to the length of the heated cigarettes, and is set at the position of the PLA hollow tube composite filter tip corresponding to the range of 1-15mm outside the outlet of the cigarettes after the cigarettes are inserted into the cigarettes, and 1-6 uniform punching holes, preferably 2-4 holes, are required along the circumferential direction; the interval between the row holes is 1-2mm, the aperture is 0.01-0.5mm, and the air permeability of the tipping paper in the punching area is 300-2000CU, preferably 800-1600CU. When the air permeability of tipping paper is lower than 300CU, the cooling effect is not obvious, and when being higher than 2000CU, the inhaled air is too much, and the flue gas concentration is too low, and experience sense is too poor.
The PLA cooling filter section is a low-absorption-resistance PLA filter rod made of PLA filament bundles with single denier more than 8D, and the absorption resistance of the PLA filter rod section is less than 150Pa/cm, and is preferably less than or equal to 100Pa/cm in order to ensure larger smoke quantity.
The length of the first hollow pipe section is 5mm-30mm, the length of the PLA cooling filter section is 5mm-20mm, and the length of the second hollow pipe section is 5mm-30mm.
The length, the shape and the size of the inner hole of the first hollow pipe section and the second hollow pipe section are the same in selectivity; when the first hollow pipe section and the second hollow pipe section are the same hollow pipe, namely the length, the shape and the size of the inner hole are the same, the two-dimensional composite mode is adopted for preparation; when the lengths, the inner hole shapes and the sizes of the first hollow pipe section and the second hollow pipe section are different, or the first hollow pipe section and the second hollow pipe section are not made of the same material, the three-dimensional composite type hollow pipe is adopted for preparation.
When the first hollow pipe section and the second hollow pipe section are the same hollow pipe and have the same length, the material rod of the hollow pipe section and the material rod of the PLA cooling section can be cut into corresponding lengths on a binary filter rod compounding machine, then the corresponding lengths are sent into a compound smoke gun, and the outside is wrapped by a layer of molding paper and is adhered by lap adhesive, and then the hollow pipe section is cut into the middle part.
The ternary combination is formed by cutting a material rod of a first hollow pipe section, a material rod of a PLA cooling section and a material rod of a second hollow pipe section into corresponding lengths on a ternary filter rod combination machine, then sending the lengths into a composite smoke gun, wrapping the materials outside by using a layer of forming paper, bonding the materials by using a lap adhesive, and then cutting the materials.
The filter stick integrates a Venturi cooling technology and a PLA cooling technology, laser drilling is carried out on the hollow pipe section, and side flow air can be introduced to further reduce the temperature of smoke. The novel heating non-combustible cigarette product has the characteristics of simple structure, simple processing technology, low production cost, good cooling effect and the like, provides a better matching material for heating cigarettes, and can meet the special requirements of the current novel heating non-combustible cigarette product on strong cooling, low pressure drop and low filtration of the filter stick, and the large atomization amount of the smoke is ensured.
