Description

Technical Field

[0001] The invention relates to the field of tobacco leaf drying, and in particular to a warehouse-type tobacco leaf drying room. Background Art

[0002] The drying process of cigar tobacco leaves is crucial to their final quality, but traditional drying methods often have the following technical problems:

[0003] 1. Imprecise temperature and humidity control in the air-drying environment: Traditional tobacco-drying rooms often lack precise temperature and humidity control systems, resulting in large fluctuations in temperature and humidity during the air-drying process, making it difficult to ensure that tobacco leaves are aired under optimal conditions, thus affecting the final quality of the tobacco leaves.

[0004] 2. Low efficiency of tobacco loading: The traditional tobacco drying method usually requires the tobacco leaves to be hung on a higher drying rack, which not only increases the labor intensity, but also limits the efficiency of tobacco loading, prolongs the drying cycle and increases costs.

[0005] 3. The thermal insulation and moisture retention performance of the air-drying environment is insufficient: The structure of the traditional tobacco air-drying room may not be conducive to thermal insulation and moisture retention, resulting in the temperature and humidity being easily affected by the external environment during the air-drying process, making it difficult to maintain a stable air-drying environment.

[0006] 4. High cost and insufficient utilization of resources: Building new tobacco drying rooms requires a lot of money and resources, while there are a large number of idle warehouses in many areas, which are not fully utilized, resulting in a waste of resources. Summary of the invention

[0007] The purpose of the present invention is to provide a warehouse-type tobacco leaf drying room to solve at least one of the above technical problems.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0018] As a further solution, two auxiliary rods are symmetrically arranged at the middle position of each layer of the tobacco drying rack, and vertical slide rails are arranged at both ends of the auxiliary rods on each layer of the tobacco drying rack. The two ends of the auxiliary rods slide up and down synchronously in the corresponding slide rails, and the auxiliary rods and a group of tobacco drying rods are arranged in a door-type structure at the position corresponding to the auxiliary rods. When the paddle pushes the tobacco leaves to gather toward one end of the tobacco drying rod, the other end of a group of tobacco drying rods is pushed gradually upward under the action of the linkage assembly, so that the tobacco drying rods form a tilted posture when collecting tobacco leaves.

[0019] As a further solution, the linkage component includes:

[0020] Wire wheels, one auxiliary rod corresponds to a group of wire wheels, and a group of wire wheels are symmetrically arranged in pairs at the bottom of each layer of the drying rack;

[0021] A steel wire rope, one end of which is connected to the end of the auxiliary rod, and the other end of which is connected to the working rod after passing through two symmetrical wire wheels;

This reduces the workload while improving the efficiency of tobacco loading, and can more accurately control the temperature and humidity during the air-drying process of cigar tobacco leaves, thereby improving the degree of homogenization of cigar tobacco leaves after air-drying. During the air-drying process, the brick wall concrete structure is more conducive to heat preservation and moisture retention. The temperature and humidity detection components and the control components are used to control the tobacco leaves to be in a suitable temperature and humidity environment, thereby achieving a higher air-drying treatment effect, improving the quality of tobacco leaves while reducing costs and increasing efficiency.

[0031] (2) The present invention adds an auxiliary mechanism, which utilizes the movement of the two ends of the automatic telescopic rod in the auxiliary mechanism to extend outward synchronously, thereby pushing the two connected working rods to move away from each other. The paddles on the working rods just concentrate the tobacco leaves on the tobacco drying rod to the edge of the drying rack. When collecting, the staff only needs to lift one end of the tobacco drying rod where the tobacco leaves are concentrated, and then gently pull the tobacco leaves off. This eliminates the need for tobacco leaves to fall off the tobacco drying rod and the labor caused by repeatedly taking and placing the tobacco drying rods, thereby comprehensively improving the overall tobacco leaf collection process, saving time and effort, being convenient and fast, and being highly practical.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 6 As shown, the present invention is a warehouse-type tobacco leaf drying room, comprising:

[0042] A humidifier and a dehumidifier are arranged in the air-drying room, and are used to adjust the humidity inside the air-drying room;

[0043] A controller, connected to the humidifier and the dehumidifier, and controlling their operation according to the received temperature and humidity information;

[0044] A temperature and humidity detection component, comprising an outdoor detection unit for detecting outdoor temperature and humidity and an indoor detection unit for detecting indoor temperature and humidity;

[0045] A control component receives a signal from the temperature and humidity detection component and sends a control instruction to the controller;

[0046] A tobacco drying rack 1 is arranged in the drying room, and the tobacco drying rack 1 is arranged in multiple layers, and multiple groups of tobacco drying rods 2 are arranged on each layer of the tobacco drying rack 1, wherein the drying room realizes precise control of temperature and humidity during the drying process through the coordinated action of the temperature and humidity detection component and the control component; an auxiliary mechanism 3 is arranged on the tobacco drying rack 1, and the auxiliary mechanism 3 is used to assist in the collection of tobacco leaves on the tobacco drying rods 2; the drying room adopts a brick wall concrete structure.

[0047] Through the above technical scheme, the existing warehouse is used to transform the drying room, and a four-layer tobacco drying rack 1 is built on each floor of the warehouse, which reduces the height of the tobacco leaves, reduces the labor workload and improves the tobacco loading efficiency. It can more accurately control the temperature and humidity of the cigar tobacco leaves during the drying process, and improve the homogenization degree of the cigar tobacco leaves after drying; during the drying process, the brick wall concrete structure is more conducive to heat preservation and moisture retention. Through the cooperation of the temperature and humidity detection components and the control components, the tobacco leaves are controlled to be in a suitable temperature and humidity environment, so as to achieve a higher drying treatment effect, improve the quality of tobacco leaves, and reduce costs and increase efficiency.

[0048] The auxiliary mechanism 3 comprises:

[0049] Automatic telescopic rods 32, a group of mounting plates 31 symmetrically distributed in pairs are arranged on both sides of each layer of the tobacco drying rack 1, the bottom ends of the automatic telescopic rods 32 are detachably fixed on the mounting plates 31, and the telescopic ends of the two symmetrically distributed automatic telescopic rods 32 are commonly connected to the same working rod 33, and a plurality of paddles 34 are connected in series on the working rod 33, and an opening 35 is arranged at the upper end of the paddle 34, and the position of the paddle 34 corresponds one by one to the arranged tobacco drying rods 2;

[0050] The automatic telescopic rod 32 is configured as a double-headed structure, and the working rods 33 connected at both ends in the initial state are gathered at the middle position of the tobacco drying rack 1 on each layer.

[0051] The present invention provides an auxiliary mechanism 3, so that after the tobacco leaves are dried, due to the excessive number of tobacco drying rods 2 and the large number of tobacco leaves hung on each tobacco drying rod 2, the staff can only choose to take each tobacco drying rod 2 out of the tobacco drying rack 1 and then collect the tobacco leaves in turn. Although the integrity of the tobacco leaves can be kept as much as possible, the above-mentioned work process is too complicated, resulting in low efficiency in collecting tobacco leaves. In order to improve the efficiency of collecting tobacco leaves, the present invention adds an auxiliary mechanism 3, and utilizes the action of the two ends of the automatic telescopic rod 32 in the auxiliary mechanism 3 to extend outward synchronously, thereby pushing the two connected working rods 33 to move away from each other, and the paddles 34 on the working rods 33 just collect the tobacco leaves on the tobacco drying rod 2 to the edge of the drying rack. When collecting, the staff only needs to lift one end of the tobacco drying rod 2 where the tobacco leaves are concentrated, and then gently pull the tobacco leaves off, eliminating the need for tobacco leaves on the tobacco drying rod 2 to fall off easily and the labor caused by repeatedly taking and putting the tobacco drying rod 2, thereby comprehensively improving the overall tobacco leaf collection process, saving time and effort, being convenient and fast, and having high practicality.

[0052] It should be noted that the height of the working rod 33 is lower than the tobacco drying rod 2, and the opening 35 on the paddle 34 just half surrounds the corresponding tobacco drying rod 2, thereby providing a positioning for placing the tobacco drying rod 2 during initial drying, and preventing drying problems caused by different spacings between the tobacco drying rods due to manual placement.

[0053] Two auxiliary rods 36 are symmetrically arranged at the middle position of each layer of the tobacco drying rack 1. Vertical slide rails 37 are arranged at both ends of the auxiliary rods 36 on each layer of the tobacco drying rack 1. Both ends of the auxiliary rods 36 slide up and down synchronously in the corresponding slide rails 37. The auxiliary rods 36 and a group of tobacco drying rods 2 are arranged at positions corresponding to the positions. A door-type structure 38 is arranged at positions corresponding to the auxiliary rods 36 and a group of tobacco drying rods 2. When the paddle 34 pushes the tobacco leaves to gather toward one end of the tobacco drying rod 2, the other end of a group of tobacco drying rods 2 is pushed gradually upward under the action of the linkage assembly 39, so that the tobacco drying rods 2 form an inclined posture when collecting tobacco leaves.

[0054] The linkage component 39 includes:

[0055] The wire wheels 391, one auxiliary rod 36 corresponds to a group of wire wheels 391, and a group of wire wheels 391 are symmetrically arranged in pairs at the bottom of each layer of the drying rack;

[0056] A steel wire rope 392, one end of which is connected to the end of the auxiliary rod 36, and the other end of which is connected to the working rod 33 after passing through two symmetrical wire wheels 391;

[0057] Both ends of the auxiliary rod 36 are rotatably connected to a sliding sleeve 393 through a torsion spring. The sliding sleeve 393 is arranged in a rectangular shape. The sliding sleeve 393 is slidably mounted on the corresponding slide rail 37. A limit piece 394 is arranged on the mounting plate 31. The limit piece 394 is arranged obliquely. The position of the limit piece 394 corresponds to the top of the slide rail 37. A tensioning wheel can be arranged according to actual needs to maintain the state of the wire rope 392. The specific installation method and the structure of the tensioning wheel can adopt the existing technology, which will not be described in detail here.

[0058] The end of the paddle 34 is wrapped with a silicone layer 4 , and passive rods 395 are fixedly provided on both sides of the auxiliary rod 36 , and the passive rods 395 are located directly below the limiting piece 394 .

[0059] In the present invention, in order to reduce the damage caused by the paddle 34 forcibly prying the tobacco leaves, an auxiliary rod 36 and a linkage assembly 39 are provided. The auxiliary rod 36 and the linkage assembly 39 are used to realize the linkage action of the auxiliary rod 36 and the paddle 34. Specifically, when the paddle 34 moves following the working rod 33, the pulling force on the auxiliary rod 36 is relaxed, and the auxiliary rod 36 moves downward under the action of its own weight, so that the sliding sleeve 393 at the end of the auxiliary rod 36 is freed from the restriction of the limit plate 394. Because the sliding sleeve 393 of the rectangular structure can only move up and down but cannot rotate, the auxiliary rod 36 itself is deflected under the action of the torsion spring, so that the auxiliary rod 36 deflects upward while moving downward, so that the door-shaped structure 38 of the original auxiliary rod 36 deflects upward, so that the auxiliary rod 36 forms an inclined posture, so that the tobacco leaves automatically slide to one side and concentrate.

[0060] It should be noted that the height of the auxiliary rod 36 after tilting is still within the range of the opening 35 of the paddle 34, so the paddle effect can be continuously implemented; the power source of the above-mentioned auxiliary rod 36 is achieved by means of the movement of the working rod 33, and the auxiliary rod 36 first descends to disengage from the limit plate 394, and then deflects under the action of the torsion spring. This time interval can be used to allow the working rod 33 to move a certain distance, and then give the door-type structure 38 of the auxiliary rod 36 sufficient deflection space to effectively act on the exposed end of the tobacco drying rod 2. The structure is compact and the action is continuous. The action of tilting to allow the tobacco leaves to automatically slide down and the action of actively plucking to one side work together, taking into account both the integrity and efficiency of tobacco leaf collection, achieving multiple goals at one stroke.

[0061] The opening 35 is provided with a movable cleaning mechanism 5, which is in an active state during the process of collecting tobacco leaves to gently gather tobacco leaves, and is in a locked state during the process of returning to strongly clean the residue on the tobacco drying rod 2. The movable cleaning mechanism 5 includes:

[0062] Soft hair 51, a plurality of soft hair 51 are arranged on both sides of the opening 35, the soft hair 51 is movably connected to the side wall of the opening 35, vertical series grooves 52 are arranged inside the two sides of the paddle 34, the series grooves 52 are connected to the tail position of the soft hair 51, the top end of the series groove 52 passes through the top of the paddle 34, and the bottom end extends to the bottom of the opening 35 and is arranged through;

[0063] A tensioning wire 53 is provided in each of the series grooves 52. The top of the tensioning wire 53 is knotted and the bottom is connected to a screw rod 54. The screw rod 54 is spirally connected to a sleeve 55. The sleeve 55 is fixed to the bottom of the opening 35. One end of the screw rod 54 is fixed to a mounting bracket 56. The mounting bracket 56 is fixed to one side of the bottom of the opening 35. The other ends of the two screw rods 54 are transmission connected through a gear set 57. A top rod 58 is provided on the tobacco drying rack 1. The top rods 58 are distributed on both sides of the tobacco drying rod 2 in groups of two.

[0064] In order to make the action of lifting and aggregating tobacco leaves gentle and adaptable to tobacco leaves of different shapes, the present invention provides an active cleaning mechanism 5. When in use, the top block on the left side supports the screw rod 54, causing it to rotate and feed to one side, thereby rotating in the opposite direction to relax the tensioning line 53. The relaxed tensioning line 53 does not apply pressure to the tail of the soft hair 51 on the same side, so that the soft hair 51 is in an active state, thereby achieving the effect of gently aggregating tobacco leaves; when the tobacco leaves are aggregated or the tobacco leaves are collected, the top rod 58 on the right side acts on the opposite screw rod 54, causing the screw rod 54 to rotate forward under force, thereby winding the tensioning line 53, and the tightened tensioning line 53 applies pressure to the tail of the soft hair 51 on the same side, so that the soft hair 51 is in a locked state, and a strong scraping effect can be achieved when returning to improve the cleaning effect. Through the above technical scheme, it is achieved that it is in an active state during the process of collecting tobacco leaves to gently gather tobacco leaves, and is in a locked state during the process of returning to strongly clean the residue on the tobacco drying rod 2;

[0065] It should be noted that the gear set 57 may include two gears and an idler wheel, and the length of the idler wheel is greater than the two gears, so that the two gears and the idler wheel are always kept in a meshing state during the feeding and retracting process of the screw rod 54. The two gears are respectively fixed to the ends of the two screw rods 54, and the idler wheel is rotatably installed on the bottom wall of the opening 35.

[0066] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
