Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment, in particular to a structure control device for cigar sheet-shaped tomato core and melon slices. Background Art

[0002] Cigars are a relatively special tobacco product. The wrapper, binder, and filler together make up a cigar, all primarily made from cigar tobacco leaves and rolled by hand or machine. For machine-rolled cigars, the filler can be either shredded or sheet-shaped. Shredded widths are primarily altered using a shredder, while sheet-shaped shapes vary due to the diverse diameters of cigars. Adjusting the sheet-shaped dimensions of the filler material primarily involves processes such as leaf deformation. Moisture and temperature control of the raw material before threshing are also crucial. Therefore, pre-processing of sheet-shaped filler material involves adjusting the moisture content of the tobacco leaves, controlling the temperature, and adjusting the sheet-shaped dimensions. These adjustments, along with systematic process methods, not only impact quality indicators like draw resistance, density, and tightness of the rolls, but also impact product style and cost-effectiveness, such as raw material loss during the process.

[0003] With the promotion and application of intensive tobacco processing, the leaves and stems of the tobacco core raw materials purchased are separated by professional threshing and redrying factories, and the leaves are threshed centrally according to certain technical and economic indicators. This has achieved the separation of the leaves and stems of the tobacco raw materials. After the redrying of the tobacco core raw materials, their quality consistency and uniformity are effectively guaranteed after industrial aging. However, the size and structure of the tobacco core raw materials after threshing and redrying still cannot meet the requirements for machine-made cigar core rolling. Therefore, the structure of the tobacco strips after threshing and redrying needs to be further controlled. The current method of structural control is to directly use a threshing machine to thresh the tobacco strips until the size requirements of the tobacco core and slices are met. Since this method directly threshes all the tobacco strips, it will result in a lot of broken tobacco core and slices. Utility Model Content

DETAILED DESCRIPTION

[0019] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0020] See also Figures 1 to 4The present embodiment discloses a structural control device for cigar-shaped cigar-core melon slices, comprising a first-level vibrating screening machine 1, a first-level leaf beater 2, an air conveying system, a second-level vibrating screening machine 3 and a second-level leaf beater 4 connected in sequence.

The feed port of the first-level leaf beater 2 is used to receive the upper material falling from the upper material discharge port of the first-level vibrating screening machine 1. The air conveying system is used to convey the material from the discharge port of the first-level leaf beater 2 to the feed end of the second-level vibrating screening machine 3 by wind. The second-level vibrating screening machine 3 is provided with an upper material discharge port and a lower material discharge port. The feed port of the second-level leaf beater 4 is used to receive the upper material falling from the upper material discharge port of the second-level vibrating screening machine 3.

[0021] A primary screening conveyor belt 5 is provided below the lower material discharge port of the primary vibrating screen 1, a secondary screening conveyor belt 6 is provided below the lower material discharge port of the secondary vibrating screen 3, and a secondary threshing conveyor belt 7 is provided below the discharge port of the secondary defoliator 4. The ends of the primary screening conveyor belt 5, the secondary screening conveyor belt 6, and the secondary threshing conveyor belt 7 converge onto the same main conveyor belt 8. The primary vibrating screen 1, the primary defoliator 2, the air conveying system, the secondary vibrating screen 3, and the secondary defoliator 4 are arranged sequentially from left to right. The primary screening conveyor belt 5, the secondary screening conveyor belt 6, and the secondary threshing conveyor belt 7 all extend in the front-to-back direction, and the main conveyor belt 8 extends in the left-to-right direction.

[0022] The air delivery system includes a fan 9 and a tangential dropper 10. Both the fan 9 and the tangential dropper 10 are located above the feed end of the secondary vibrating screen 3. The fan 9 outlet, return air duct 11, the discharge port of the first-stage defoliator 2, the air delivery duct 12, the feed port of the tangential dropper 10, the air delivery duct 12, and the air inlet of the fan 9 are sequentially connected to form a circulating air path. The discharge port of the tangential dropper 10 is located above the feed end of the secondary vibrating screen 3. The return air duct 11, the discharge port of the first-stage defoliator 2, and the air delivery duct 12 are connected by a tee joint 13. The air delivery duct 12 is a flat tube, and the return air duct 11 is a square tube. The end of the return air duct 11 is connected to the tee joint 13 via a reducer. The air conveying system is provided to provide a negative pressure adsorption function for the first-stage leaf beater 2, thereby improving the ability of melon slices to fall through the leaf beating frame 18 during the tearing process between the movable knife 19 of the first-stage leaf beater 2 and the leaf beating frame 18, so that melon slices that meet the size of the leaf beating frame 18 can quickly pass through the leaf beating frame 18 and enter the air conveying duct 12, avoiding the accumulation of melon slices under the movable knife roller 20 and the resulting breakage caused by repeated beating, thereby effectively reducing the generation of breakage.

[0023] The first-level vibrating screening machine 1 and the second-level vibrating screening machine 3 include a vibrating frame 14 and two upper and lower sieve plates mounted on the vibrating frame 14. The length of the upper sieve plate 15 in the left-right direction is shorter than the length of the lower sieve plate 16. The upper sieve plate 15 is used to evenly spread the incoming material to facilitate smooth screening operations and improve screening quality on the lower sieve plate 16. The upper sieve plate 15 and the lower sieve plate 16 are detachably mounted on the vibrating frame 14. The upper sieve plate 15 can be mounted on the vibrating frame 14 using a clamp, while the lower sieve plate 16 can be mounted on the vibrating frame 14 using screws. The first-level defoliator 2 and the second-level defoliator 4 both include a defoliating frame 17 and a defoliating frame 18 disposed within the defoliating frame 17. The defoliating frame 18 is detachably connected to the defoliating frame 17. There are generally two specifications of cigar sheet fillers, namely 14.8mm diameter specification and 9.1mm diameter specification. By switching the screen plates and leaf-beating frames 18 of different sizes at different levels, the size control requirements of cigar sheet fillers of different specifications can be achieved.

[0024] During operation, the sheet-shaped raw material of the tobacco core is heated and humidified as the material to be conditioned. The material to be conditioned is then fed into the first-stage vibrating screening machine 1 for first-stage screening. The upper layer of the material after the first-stage screening is the first-stage screening upper layer material, and the lower layer of the material after the first-stage screening is the first-stage screening lower layer material. The lower layer of material after the primary screening falls onto the primary screening conveyor belt 5 below. The upper layer of material after the primary screening enters the primary defoliator 2. After the primary defoliation process in the primary defoliator 2, it becomes the primary defoliation material. The primary defoliation material enters the air conveying system through the discharge port of the primary defoliator 2. Under the action of the wind of the air conveying system, the primary defoliation material enters the tangential dropper 10 through the air conveying pipe 12. After the gas-material separation in the tangential dropper 10, the material falls onto the feed end of the secondary vibrating screening machine 3. After the secondary screening process by the secondary vibrating screening machine 3, the upper layer of material after the secondary screening process becomes the secondary screening upper layer material, and the lower layer of material after the secondary screening process becomes the secondary screening lower layer material. The lower layer of material after the secondary screening falls into the secondary screening lower layer material below. The upper layer of material after the secondary screening enters the secondary defoliator 4. After the secondary defoliation process in the secondary defoliator 4, it becomes the secondary defoliation material. The secondary defoliation material falls onto the secondary defoliation conveyor belt 7 below. The primary screening conveyor belt 5, the secondary screening conveyor belt 6 and the secondary leaf-beating conveyor belt 7 gather the materials onto the main conveyor belt 8, and finally the main conveyor belt 8 transports the materials to the next process.
