Method for preparing heating but incombustible cigarettes and application thereof

The invention discloses a method for preparing heating but incombustible cigarettes and application thereof. The method and the application have the advantages that novel knurling rolling technologiesare adopted, accordingly, heating but incombustible reconstituted tobaccos with certain thicknesses have uneven surfaces, the surface areas can be enlarged, atomization effects can be enhanced, and surface frictional force can be enlarged; embossed composite aluminum-foil cigarette paper is adopted, accordingly, friction between the reconstituted tobaccos and aluminum-foil pattern surfaces of thecomposite aluminum-foil cigarette paper which is a cigarette making and plug assembling material can be greatly enhanced when the reconstituted tobaccos and the composite aluminum-foil cigarette paper are loaded in a cigarette making and plug assembling machine and cigarette making and plug assembling are powered on in later periods, the heating but incombustible cigarettes are easy to process, equipment shutdown frequencies can be reduced, the heating but incombustible cigarettes can be continuously produced, the production efficiency can be improved, and the material cost and the productioncost can be reduced; low-temperature cigarettes have short cut tobacco sections, accordingly, friction can be improved, the method is beneficial to reducing cut tobacco dropping, and the shortcomingsof low frictional force between smooth surfaces of existing heating but incombustible reconstituted tobaccos and non-embossed aluminum-foil paper which is a wrapping material, severe slipping, frequent equipment shutdown due to incapability of driving cigarette paper, influence on production efficiency, low frictional force due to short cut tobacco sections of existing low-temperature cigarettes,vulnerability to dropping of low-temperature cut tobaccos of the existing low-temperature cigarettes and the like can be overcome.

Undisturbed soil sampler and sampling method

ActiveCN105928740AReduce dropDrop does not affectWithdrawing sample devicesEngineeringDrill bit
The invention relates to an undisturbed soil sampler and a sampling method. The undisturbed soil sampler comprises a drill bit, wherein the drill bit is connected with one end of a drill rod, and the other end of the drill rod is connected with a power box for driving the drill rod to rotate; the drill bit comprises a soil container connected with the drill rod, and a tool bit arranged at the end part of the soil container and used for cutting soil; the side wall of the soil container is provided with a soil cutter in an embedding manner, and the edge direction of the soil cutter is perpendicular to the axis of the soil container; and the soil cutter is connected with a mover driving the soil cutter to rotate and enabling the tool bit at the front end of the soil cutter to transversely cut into the soil in the soil container. The drill rod is driven by the power box to rotate, and the drill rod can drive the tool bit to rotate so as to cut the soil; by virtue of the rotation of the drill bit, the soil at the center enters the soil container, the soil after the drilling can be completely taken out by virtue of the soil container, the situation that the drill rod cannot be unplugged is avoided, a hole position is prevented from being changed in the drilling process, and the drilling efficiency and quality can be improved. By adopting the undisturbed soil sampler and the sampling method, an undisturbed soil sample can be obtained in the case of little disturbance.

Metal formed die gravity tilt casting process of aluminum alloy cylinder cover

The invention discloses a metal formed die gravity tilt casting process of an aluminum alloy cylinder cover, comprising the following steps of: producing a water jacket cavity, an airway cavity and an oil cavity of the aluminum alloy cylinder cover into a plurality of sand cores according to the decomposition and producing procedures of the sand cores; placing the sand cores into a metal formed die; pressing the sand cores at the dead head; tilting the metal formed die to 90 degrees to ensure that a filtering port of a sprue cup to face upward; pouring aluminum liquid into the filtering port to enter the sprue cup; tilting and returning the metal formed die by the speed control of low speed, high speed and low speed in the tilting process to ensure that the aluminum liquid enters the metal formed die; opening a negative pressure exhausting system to exhaust gas; opening a water-cooling system to cool parts of a combustion chamber on the cylinder cover until a casting is discharged from the die; and cooling the casting to obtain an aluminum alloy cylinder cover casting. The invention can be used for producing the aluminum alloy cylinder cover casting with the advantages of thin wall, complication, high mechanical property, compact surface and bright color and has the characteristics of short production period, low cost of the casting and high production efficiency, yield and qualification rate.

Hot-metal bottle tipping device with weighing

InactiveCN102909361ASmall drop in molten ironLess splashing of molten ironMelt-holding vesselsCasting parameters measurement/indication devicesEngineeringOperation safety
The invention relates to a hot-metal bottle tipping device with weighing, belonging to the technical field of casting. The hot-metal bottle tipping device with weighing comprises a tilting shaft (1), a fixed bracket (2), a tilting hydraulic cylinder (3), a tilting bracket (4), a safety hook (7) and a weighing pressure head (10), wherein the fixed bracket (2) is composed of a tilting shaft bracket (8) and a base (9) and is fixed on a ground foundation or a tipping work platform of a hot-metal bottle (6); the weighing pressure head (10) is positioned below the fixed bracket (2); the safety hook (7) is welded on the tilting bracket (4); and the tilting hydraulic cylinder (3) is arranged below the tilting bracket (4). The hot-metal bottle tipping device has the advantages of being capable of ensuring that an tipping angle of the hot-metal bottle can be more than 90 degrees and preventing the hot-metal bottle from slipping simultaneously, being safe and reliable to operate, and being capable of accurately controlling the casting speed and flow rate of molten iron so as to ensure that the little molten iron is spattered during casting, and the environmental pollution is little, and therefore, the device is suitable for casting work of pig casting machines in metallurgical production enterprises.
