Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco production auxiliary equipment, and in particular relates to a tobacco liquid stirring device. Background Art

[0002] Tobacco liquid gives cigarettes a unique smoking style and plays an extremely important role in cigarette production. In the production of silk, the liquid is uniformly configured by the flavoring kitchen, and then sent to the feeding tank at the production site by tank or pipe. Due to the particularity of the liquid and the impact during the feeding process, there is foam on the upper layer of the liquid sent to the feeding tank. If the foam is not eliminated in time, the foam will enter the feeding pipeline in the middle and late stages of production, which will affect the feeding accuracy and feeding uniformity. In severe cases, it will cause production interruption and affect the production process indicators.

[0003] In addition, due to the special nature of the liquid feed, the liquid feed is prone to stratification, crystallization and precipitation after being left to stand. Therefore, before normal use, it needs to be stirred manually to mix and eliminate crystallization and precipitation. This process is time-consuming and labor-intensive and has limited effect. If the crystallization and precipitation in the liquid feed cannot be eliminated in time, on the one hand, the liquid feed application effect is affected, thereby affecting the sensory quality of the cigarette product. On the other hand, due to the presence of crystallization and precipitation, the feeding pipeline and feeding nozzle are easily blocked, thus affecting normal production. Utility Model Content

[0004] The purpose of the utility model is to provide a tobacco liquid stirring device, which, through the stirring of the stirrer and the combined action of ultrasonic waves, can eliminate the foam on the upper layer of the liquid in the feeding tank and the crystallization and precipitation in the liquid, so that the liquid tends to be homogenized, thereby improving the stability of the flavoring material when it is applied, and enhancing the effect of tobacco leaves absorbing the flavoring material, so as to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above objectives, this application is implemented through the following technical solutions:

[0006] A tobacco liquid stirring device comprises a stirring motor, which is arranged on the top surface of a feeding tank, a driving gear is installed on the output shaft of the stirring motor, and a driven gear is installed on the upper end of a stirring rod extending out of the top of the feeding tank, wherein the driving gear meshes with the driven gear.

[0007] The lower end of the stirring rod is located in the feeding tank and is connected to the ultrasonic component. The lower end of the ultrasonic component is connected to a connecting rod. A paddle stirrer is installed at the lower end of the connecting rod. A gravity sensor is arranged at the bottom of the feeding tank. The gravity sensor is connected to the PLC controller by electrical signals.

[0008] Furthermore, it comprises a protective cover which is arranged on the top of the feeding tank and covers the output shaft of the stirring motor, the driving gear and the driven gear.

[0009] Furthermore, the stirring rod is a hollow structure, and an outer nut is provided on the outer side surface of the lower end of the stirring rod.

[0010] Furthermore, the ultrasonic component includes an ultrasonic generator and an amplitude variation device, both ends of the amplitude variation device are respectively connected to the stirring rod and the connecting rod, and the ultrasonic generator is arranged around the amplitude variation device to form an ultrasonic array.

[0011] Furthermore, the amplitude varying device is a hollow structure, and couplings are provided at both ends of the amplitude varying device, which are respectively connected to the stirring rod and the connecting rod.

[0012] Furthermore, a conductive slip ring is provided at the portion of the stirring rod extending out of the top of the feeding tank, which is used for routing the ultrasonic array on the amplitude varying device.

[0013] The beneficial effects of the utility model are:

[0014] This technical solution uses agitator stirring and ultrasonic homogenization and defoaming to solve the problems of stratification, crystallization and precipitation of tobacco liquid, and obtains stable and uniform liquid. At the same time, the foam on the upper layer of the liquid is eliminated in time in the early stage of production, avoiding the problem of reduced feeding accuracy and feeding uniformity caused by foam entering the feeding pipeline. The feeding process applies a uniform and stable liquid, ensuring the process quality and homogeneity of cigarette products.

[0015] The existing direct connection mode between the stirring motor and the stirring rod is changed, and the power transmission between the stirring motor and the paddle agitator is completed by the meshing of the driving gear and the driven gear, thereby avoiding the problem of oil leakage from the stirring motor (including the reducer), and the oil directly seeping into the material tank along the stirring rod to pollute the material liquid and cause major process quality accidents.

[0022] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0023] See also Figures 1 to 4 The present application provides a tobacco liquid stirring device, including a stirring motor (including a reducer) 1, a protective cover 2, a paddle stirrer 4, a conductive slip ring 6, an ultrasonic generator, a transducer, a variable amplitude device 3, a gravity sensor 5, a PLC controller (not shown in the figure), etc.

[0024] The stirring motor 1, the driving gear 7, the driven gear 8 and the protective cover 2 are all arranged on the top upper surface of the feeding tank.

[0025] A driving gear 7 is installed on the output shaft of the stirring motor, and the upper end of the stirring rod 9 extends out of the top of the feeding tank and is equipped with a driven gear 8. The power transmission from the stirring motor to the paddle stirrer is completed by the meshing of the driving gear 7 and the driven gear 8; the protective cover 2 covers the output shaft of the stirring motor and the driving and driven gears to prevent people from being injured by accidental contact; the stirring rod 9 is a hollow structure, which is conducive to the routing of the amplitude varying device 3.

[0026] The lower end of the stirring rod 9 is located in the feeding tank and is connected to the ultrasonic component. The lower end of the ultrasonic component is connected to a connecting rod 10. A paddle stirrer 4 is installed at the lower end of the connecting rod 10. A gravity sensor 5 is arranged at the bottom of the feeding tank. The gravity sensor 5 is electrically connected to the PLC controller.

[0027] In the technical solution of the present application, the control method of the PLC controller is conventional control and does not involve special control. It is only used to receive the signal of the gravity sensor to determine whether it is within the set range, and then control the closing or opening of the ultrasonic component. Therefore, in the technical solution of the present application, there is no detailed description of how to control. Those skilled in the art can obtain PLC sensors and gravity sensors through commercial channels and connect them according to the instructions to achieve the closing or opening of the ultrasonic component of the present application.

[0028] The ultrasonic component of the present application includes an ultrasonic generator and an amplitude variation device 3, the two ends of the amplitude variation device are respectively connected to the stirring rod 9 and the connecting rod 10, and the ultrasonic generator is arranged around the amplitude variation device to form an ultrasonic array. The ultrasonic generator includes a transducer, which is a conventional technology. The ultrasonic generator, the transducer and the amplitude variation device are used in combination, and the sound pressure effect and cavitation effect of the ultrasonic wave in the liquid are used to break the crystals in the liquid, expand the crystal surface area, and accelerate the dissolution, thereby ensuring the uniformity of the liquid configuration and achieving the homogenization of the liquid; at the same time, the ultrasonic energy can cause the foam on the upper layer of the liquid to break, so as to eliminate bubbles and improve the stability of feeding. When working, the ultrasonic generator converts the mains electricity into high-frequency alternating current that can drive the transducer to work, and the transducer converts the electrical energy into mechanical vibration. The vibration wave generates sound pressure and cavitation effect through the amplitude variation device immersed in the liquid.

[0029] The amplitude device 3 is a hollow structure, and couplings 31 are provided at both ends of the amplitude device, which are connected to the stirring rod and the connecting rod respectively. The ultrasonic array around the amplitude device is used to transmit the sound pressure effect and cavitation effect of the ultrasonic wave to the liquid material, which plays a role in homogenizing and defoaming the liquid material; the conductive slip ring is used for routing the ultrasonic array of the amplitude device to prevent the electrical circuit from being entangled during the stirring process.

[0030] The PLC controller is used to receive the electrical signal of the gravity sensor at the bottom of the feeding tank. When the liquid in the feeding tank cannot immerse the amplitude adjustment device in the middle and late stages of production (that is, when the weight of the liquid in the feeding tank is lower than a certain value), the PLC controller delays the shutdown of the ultrasonic generator and stops the ultrasonic homogenization and defoaming treatment of the liquid.

[0031] The working principle is:

[0032] In the early stage of production, the liquid feed is sent from the kitchen can or pipe to the feed tank at the production site. After the feeding is completed, the PLC controller starts the ultrasonic generator to achieve ultrasonic homogenization and defoaming of the liquid feed while stirring it. Through the sound pressure and cavitation effect of ultrasound, tens of thousands of tiny bubbles are generated in the liquid feed. The tiny bubbles vibrate in the sound field. When the sound pressure reaches a certain value, the bubbles grow rapidly and suddenly close. The shock wave generated when closing can break and disperse the undissolved crystals and insoluble solid substances in the liquid feed, and cooperate with the stirring of the agitator to achieve the effect of homogenizing the liquid feed; at the same time, the shock wave generated can break the foam on the upper layer of the liquid feed, achieving the purpose of defoaming the liquid feed. Because ultrasound is a purely physical means, the homogenization and defoaming process will not affect the properties of the raw material liquid.

[0033] In the middle and later stages of production, when the liquid in the feeding tank cannot submerge the amplitude varying device, the PLC controller will delay shutting down the ultrasonic generator and stop ultrasonic treatment of the liquid. The agitator will keep stirring during the entire feeding process.

[0034] It should be noted that the ultrasonic homogenization and defoaming process is intermittent. The ultrasonic time should not be too long each time. The intermittent time should be greater than or equal to the ultrasonic time, which is conducive to the heat dissipation of the ultrasonic equipment. For example: ultrasonic for 10 minutes every 30 minutes, and repeat this process. The working power of the ultrasonic generator should be selected within the range of 15-40kW.

[0035] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the protection scope of the present invention.
