Description

Technical Field

[0001] The invention belongs to the technical field of agricultural product selection devices and supporting operations, and specifically relates to a device and method for flattening and shaping cigar tobacco leaves as raw materials for cigar wrappers and cigar wrappers. Background Art

[0002] Cigars are a special hobby consumer product with a high market price. They are generally made by hand from tobacco leaves, and the outer leaves are generally called wrappers and binders. The quality requirements of the raw tobacco leaves for wrappers and binders are high. The leaves must be complete, without damage or disease spots, with a flat leaf surface, uniform color, fine and flat veins, soft and tough. Special technologies are required for field planting, drying and fermentation of the raw materials. In the fermentation process, a flattening and shaping process is required to flatten the leaves. Flattening means that the selected tobacco leaves of the same quality grade are unfolded piece by piece according to the appearance quality regulations of the wrapper and binder tobacco leaves, and then made into 20 to 25 pieces / handle of flattened tobacco. Shaping means that the flattened tobacco is spread out layer by layer on the tray device, with a moderate weight on it, and placed in a room with suitable temperature and humidity for 12 hours to prevent the leaves from shrinking and keep the leaf surface flat.

[0003] At present, the domestic operation of spreading and shaping wrapper tobacco leaves is generally done manually. The leaf spreading tray device used is generally a platform or a flat plate. That is, the tobacco leaves are spread layer by layer on a smooth platform or a flat plate, and the surface of each leaf is flattened by hand, and then pressed with another flat plate. After being left for a period of time, when the wrinkles on the surface of the tobacco leaves no longer shrink and curl up, they can be tied into bundles and transferred to the fermentation site.

[0004] This operation method is labor-intensive and time-consuming, with low operating efficiency, insufficient leaf spreading effect, inconvenient transportation during shaping, and large space occupation, which is not conducive to fast, process-oriented, and intensive flattening and shaping operations. Therefore, it is urgent to improve the flattening and shaping device and method in cigar production and finishing to improve finishing efficiency, reduce labor input, and improve leaf spreading and flattening effect. Summary of the invention

[0005] The purpose of the present invention is to provide a device and method for flattening and shaping cigar tobacco leaves as raw materials for cigar wrappers and cigar wrappers, so as to solve the above-mentioned problems existing in the prior art.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] In one aspect, the present invention provides a device for flattening and shaping cigar tobacco leaves as raw materials for wrappers and cigar wrappers, comprising:

[0015] The convex surface of the first curved plate is arranged upward, and multiple layers of cigar tobacco leaves are laid in sequence from bottom to top on the convex surface of the first curved plate according to the required number of bundles, wherein the curling directions of any two adjacent cigar tobacco leaves are opposite, and the back side of the curling direction of a cigar tobacco leaf that is in contact with the first curved plate is in contact with the first curved plate;

[0016] The concave surface of the second curved plate is pressed downward against the upper ends of all cigar tobacco leaves for shaping for 3-12 hours. When the cigar tobacco leaves do not shrink or curl after the second curved plate is removed, shaping is completed.

[0017] As a preferred technical solution of the present invention, when laying cigar tobacco leaves, the surface of the cigar tobacco leaves is quickly stretched from front to back and from the main vein to the leaf edge to complete the laying of the cigar tobacco leaves.

[0018] Beneficial effects: The present invention designs the first curved plate and the second curved plate to be curved plates with an area larger than that of the cigar leaves, so that the cigar leaves can be fully spread out on the first curved plate, and after being repeatedly flattened and spread out, they are pressed and shaped, so that the surface of the cigar leaves is flatter and less likely to curl and shrink, which is beneficial to improving the appearance quality of the cigar wrapper and cover leaves. In practice, only two people are needed to cooperate with each other to improve the efficiency of the sorting operation, reduce labor input, realize process-based and assembly-line operations, improve the effect of spreading and flattening the leaves, and the overall space occupied during the shaping stage is small, which is convenient for storage.

Both the length and the width can cover the cigar leaves 2. Combined with a certain arc, after the shaping is completed, the cigar leaves 2 can be spread more fully, and the cigar leaves 2 can be better guaranteed not to shrink and curl.

[0029] As a preferred implementation scheme in this embodiment, it needs to be further explained that the second arc-shaped plate 3 is made of wood, bamboo, lightweight metal or food-grade plastic, all of which are environmentally friendly materials and will not affect the subsequent construction of the cigar tobacco leaves 2.

[0030] As a preferred implementation scheme in this embodiment, it needs to be further explained that the length of the second arc-shaped plate 3 is 60-80 cm, the arc width is 30-40 cm, and the curvature is 90-180°. Both the length and the width can cover the cigar leaves 2, and the curvature will not be too large.
