Description

Technical Field

[0001] The utility model relates to the technical field of tobacco manufacturing, in particular to an easily foldable and shrinkable upper tobacco leaf with stem baking air distribution grid. Background Art

[0002] The current tobacco leaf curing room mainly includes the curing room body, heat source, controller, heat exchanger, circulating fan and dehumidification system. The curing room generally includes a heating chamber and a tobacco hanging chamber; the heat source is used to burn fuel to generate heat, and the fuel used is divided into solid, liquid and gaseous fuels. The controller is a device that automatically controls the start and stop of the heat source, the high and low speed of the circulating fan, and the dehumidification system according to the temperature and humidity in the tobacco hanging chamber; the heat exchanger is an ordinary air heat exchanger, which can heat and circulate the air inside and outside the curing room through the heat exchanger with the heat generated by the heat source; the circulating fan is generally a one-way circulating fan, which introduces the hot air heated by the heat exchanger into the tobacco hanging chamber and circulates it into the heating chamber for one-way circulation.

[0003] In the prior art, tobacco leaves are baked in a baking room, but the upper tobacco leaf stems contain a large amount of moisture, which makes it difficult to dehumidify in the later stage, resulting in a long baking time and high energy consumption. It is necessary to adjust the hot air coverage and dynamic distribution in the baking room. Conventionally, the wind grids in the tobacco leaf baking room are fixed in the baking room, which is not convenient to move and adjust the specifications, resulting in a fixed hot air coverage area. The fixed tip wind speed is not conducive to the dehumidification of tobacco leaves and tobacco stems. Although fan frequency conversion can achieve this process, it requires investment in frequency conversion equipment, power lines, and programming of tobacco flue-cured control instruments, etc., and there are large differences in the nutritional quality of regional tobacco leaves due to ecological influences, which requires later research.

[0004] In view of this, it is urgent to design an easily foldable and shrinkable upper tobacco leaf with stem baking air distribution grille, reform the conventional air distribution grille into multiple groups of wind distribution units connected together, and connect the air distribution units to each other through a scissor-shaped connection structure, so that the air distribution units can be telescopically folded. At the same time, by adding a telescopic and adjustable linkage beam to the air distribution unit, the air distribution units can be synchronously driven to rotate synchronously, ensuring the adjustment of the air outlet direction of the air distribution grille, and solving the problem of slow dehydration of the stems of the upper leaves during the later drying.

[0006] Further, the air distribution unit includes: an air distribution base, a rotating shaft base, a rotating shaft and a power arm. The rotating shaft base is fixedly installed on the side wall surface of the air distribution base. The rotating shaft is rotatably connected in the rotating shaft base. The power arm is fixedly installed at the end of the rotating shaft.

[0007] Further, the scissors structure includes: a connecting seat, fork arms and a connecting rotating shaft.

[0015] As shown in the figure, the present utility model discloses an upper tobacco leaf stem-baking air-distributing grille that is easy to fold and shrink, including: an air-distributing unit 1, a scissors structure 2, a mounting seat 3, and a guiding beam structure 4.

[0016] In this embodiment, the air-distributing unit 1 includes: an air-distributing seat 11, a rotating shaft seat 12, a rotating shaft 13, and a power arm 14.

[0017] In this embodiment, the scissors structure 2 includes: a connecting seat 21, fork arms 22, and a connecting rotating shaft 23. The connecting seat 21 is fixedly installed on the side wall surface of the air-distributing seat 11. One end of the fork arm 22 is rotatably connected to the connecting seat 21. The other ends of the fork arms 22 are connected to each other through the connecting rotating shaft 23. A parallelogram structure is formed between the fork arms 22.

[0018] In this embodiment, the mounting seat 3 includes: mounting side plates 31 and telescopic through holes 32. The telescopic through holes 32 are opened on the mounting side plates 31. The guiding beam structure 4 is installed in the telescopic through holes 32.

[0019] In this embodiment, the guiding beam structure 4 includes: a unit beam 41, a telescopic cylinder 42, a steering hole 43, and a telescopic cylinder 44. The telescopic cylinder 42 is installed on one side of the unit beam 41. The telescopic cylinder 42 is sleeved on one end of the unit beam 41. The steering hole 43 is opened on the unit beam 41. The steering hole 43 is rotatably connected to the power arm 14. The telescopic cylinder 44 is fixedly installed on one side of the mounting side plate 31. The power end of the telescopic cylinder 44 passes through the telescopic through hole 32 and is power-connected to the unit beam 41.

[0020] Working principle:

[0021] First, since there is a wind distribution unit 1, a wind distribution plate is installed on the wind distribution unit 1. The wind distribution unit 1 is composed of a wind distribution base 11, a rotating shaft seat 12, a rotating shaft 13, and a power arm 14. A rotating shaft seat 12 is fixedly installed on one side of the wind distribution base 11. The rotating shaft 13 is rotatably connected to the rotating shaft seat 12, and the power arm 14 is fixedly connected to the end of the rotating shaft 13. The rotation direction of the rotating shaft 13 is adjusted by using the rotation direction of the power arm 14.

[0022] Among them, a scissor structure 2 is installed between the wind distribution bases 11. The scissor structure 2 is composed of a connecting seat 21, a fork arm 22, and a connecting rotating shaft 23. The connecting seat 21 is fixedly installed on the side wall surfaces of the two wind distribution bases 11. The fork arm 22 is rotatably connected to the connecting seat 21, and the fork arms 22 are rotatably connected to each other through the connecting rotating shaft 23. Thus, a parallelogram is formed between the fork arms 22, which facilitates the deformation of the fork arms 22 to achieve the effects of mutual stretching, contraction, and folding between the wind distribution units 1.

[0023] Among them, the mounting seat 3 is composed of mounting side plates 31 and telescopic through holes 32. A guiding beam structure 4 is bridged between the mounting side plates 31, and the wind distribution base 11 is also installed on the side wall surface of the mounting side plate 31. Telescopic through holes 32 are opened on the mounting side plates 31, and the guiding beam structure 4 telescopes between the telescopic through holes 32.

[0024] Among them, the guiding beam structure 4 is composed of a unit beam 41, a telescopic cylinder 42, a steering hole 43, and a telescopic cylinder 44. The telescopic cylinder 44 is fixedly installed on the mounting side plate 31, and the power end of the telescopic cylinder 44 passes through the telescopic through hole 32 and is power-connected to the unit beam 41. A telescopic cylinder 42 is installed on one side of the unit beam 41, and the telescopic cylinder 42 is sleeved on the end of another unit beam 41. A steering hole 43 is opened on the unit beam 41, and the power arm 14 is rotatably connected to the steering hole 43.

[0025] Thus, when stretching or telescoping is required, the scissor structure 2 connected between the wind distribution units 1 deforms, so that a displacement is generated between the wind distribution units 1. At the same time, the relative positions between the unit beam 41 and the telescopic cylinder 42 need to be adjusted.

[0026] When the wind distribution plate needs to rotate, the telescopic cylinder 44 telescopes in the horizontal direction, thereby driving the guiding beam to displace in the horizontal direction, thereby driving the power arm 14 to rotate and driving the wind distribution plate to rotate.

[0027] An upper tobacco leaf with-stem baking air distribution grid that is easy to fold and contract provided by the present utility model reforms the conventional air distribution grid into a structure in which multiple air distribution units are connected together. The air distribution units 1 are connected to each other through a scissor-shaped connection structure, so that the air distribution units 1 can be telescopically folded with each other. At the same time, by installing a telescopically adjustable linkage beam on the air distribution unit 1, the air distribution units 1 can be synchronously driven to rotate synchronously, ensuring the adjustment of the air outlet direction of the air distribution grid.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
