Abstract

The application belongs to the technical field of cigarette production equipment, and particularly relates to a fully-sealed emulsion bag for cigarette production, a preparation method, application and a use method thereof. The latex bag comprises a latex bag top (1), a latex bag main body (2) and a latex bag bottom (3) which are connected from top to bottom, wherein the latex bag main body (2) is in a cuboid shape, the latex bag top (1) is of an organ-shaped structure and/or the latex bag bottom (3) is of an organ-shaped structure, the latex bag top (1) is provided with an air vent (4), and the latex bag bottom is provided with a glue outlet (5) and a glue injection port (6). The application creatively prepares the fully-sealed emulsion bag by the cylindrical polytetrafluoroethylene film, and adopts the organ-shaped design at the top sealing position and/or the bottom sealing position of the fully-sealed emulsion bag so that the fully-sealed emulsion bag can freely extend up and down along with the filling amount of emulsion, thereby avoiding the situation that the glue bag is propped up and damaged because the shape of the glue bag and the wall of the glue barrel cannot be effectively attached in the filling process and cannot be unfolded.

Description

Full-sealed emulsion bag for cigarette production, preparation method, application and using method thereof Technical Field The invention belongs to the technical field of cigarette production equipment, and particularly relates to a fully-sealed emulsion bag for cigarette production, a preparation method, application and a use method thereof. Background The emulsion is one of the indispensable raw materials in the cigarette production process, and is mainly used for cigarette lap bonding, tipping paper bonding, small box and carton bonding and the like. The emulsion is stored in an open container because continued exposure to air causes continued loss of moisture from the emulsion, which can lead to drying of the emulsion, interfere with its use and cause quality problems in subsequent product processing. The specific working principle of latex supply in cigarette production is that the latex is stored in a steel cylindrical container, namely a rubber barrel, and the container is buckled and sealed with a cylinder cover with a sealing strip. The power of the motor of the glue pump is not too high due to the fact that the latex smearing amount of the coiling forming machine and the glue feeding flow of the glue gun are limited, and in order to enable the latex pumped by the glue pump to be stable, the sufficient and stable glue quantity flowing to the inlet of the glue pump must be ensured. In order to ensure that latex can smoothly and stably flow to the inlet of the latex pump during operation, compressed air is injected into the container through an air socket on the cylinder cover, which is the same as the interior of the container. Thus, after the switch at the bottom of the rubber barrel container is opened, the latex flows to the inlet of the rubber pump through the rubber pipe connected with the inlet of the rubber pump at the bottom of the cylindrical container under the combined action of gravity and compressed air pressure, and is pumped to the rubber feeding device by the rubber pump. When the equipment is to be started, the compressed air switch is turned on after the switch at the bottom of the rubber barrel is turned on. After the equipment is started, the latex is continuously sent to the inlet of the glue pump under the action of compressed air and gravity, and is continuously pumped to the gluing device by the glue pump, so that the subsequent gluing process is completed. The latex is supplied under the combined action of compressed air, self gravity and a motor of a latex pump. The latex in the rubber barrel is conveyed to the inlet of the rubber pump under the combined action of the pressure of compressed air, the gravity of the latex and the suction of the rubber pump, and then is conveyed to the gluing device for gluing by the rubber pump. Due to the compressed air, the upper latex is immersed in the air for a long time. Over time, the latex reacts with air, causing the gel to form lumps. When latex is added again, the agglomerates formed on the surface settle to the lower layer. In addition, if the emulsion storage device is not tightly sealed, air leakage occurs and moisture in the emulsion is taken away, and the emulsion can form caking. When the caking is mixed into the latex and flows into a pipeline along with the latex, the blocking easily causes the unsmooth or blockage of a rubber supply pipeline, so that the unsmooth rubber supply is caused, and a series of problems such as running, bursting and the like are generated. In addition, under the continuous action of compressed air, tiny bubbles dissolved in the latex can be increased, and the performance of the latex is affected. In addition, during production, the cylinder head is opened if the compressed air is unstable or when the glue is added. At this time, the force balance formed by the suction force of the rubber pump, the pressure of compressed air and the gravity of the rubber in the rubber supply pipeline is broken, so that the micro-bubbles uniformly distributed in the rubber can move and form bubble chains or large bubbles. When the large bubbles or bubble chains are fed into the gluing device together with latex, uneven and discontinuous gluing is caused, and a series of problems such as less gluing, strip running, shutdown, cigarette bursting and the like are caused. One existing solution is to use a latex bag made of polyethylene to solve the above-mentioned problems. Specifically, a latex bag made of polyethylene is arranged in a cylindrical sealed latex barrel. The latex bag isolates latex from external air to prevent the latex from drying in a sealed space, thereby achieving the aims of maintenance and cleaning free. The manufacturing method of the polyethylene latex bag comprises the steps of folding a piece of polyethylene film along the middle part of the polyethylene film, and then heat-sealing the other three sides by related tools to realize the sealing of the polyethylene film, so as to form the polyethy
