Description

Technical Field

[0001] The utility model belongs to the field of tobacco leaf drying, and particularly relates to a tobacco leaf drying device. Background Technique

[0002] Tobacco leaf drying is an important step in the tobacco processing process, which is used to dry and oxidize the picked tobacco leaves; the purpose of drying is to remove the moisture in the tobacco leaves so that they reach an appropriate moisture content and texture for subsequent processes such as fermentation and baking; tobacco leaf drying is usually carried out in specific drying places, which can be indoor or outdoor facilities; during the drying process, the tobacco leaves are scattered on the racks or wire meshes in the drying places to facilitate air circulation and uniform drying of the tobacco leaves.

[0003] According to a Chinese patent publication No. CN103263068A, it points out a tobacco leaf drying device for sun-cured tobacco; in this cited document, the tobacco leaves can be fixed by clamping with clips on two bimetallic strips, and then the fixture with the fixed tobacco leaves can be placed on the bracket for drying. During the use of this special fixture, since the tobacco leaves are evenly spread between the two metal strips and the thickness of the tobacco leaves is uniform, the drying time of the tobacco leaves can be shorter, the drying time of the tobacco leaves can be more uniform, and the processes of tying and untying the tobacco can be omitted, reducing the drying process, reducing the damage to the tobacco leaves during the operation process, and ensuring the quality of the tobacco leaves;

[0004] In the actual use of the above-cited patent, although the stable clamping of the tobacco leaves is achieved, it still has certain defects in use, that is, the drying of the tobacco leaves in this document mainly relies on the external natural wind for drying. When the external weather is bad and the natural wind force is small, the drying time of the tobacco leaves is longer, and there will be a difference in the drying length between the upper and lower tobacco leaves, resulting in uneven drying of the tobacco leaves and inconsistent overall drying quality of the tobacco leaves; at the same time, when the air volume is small, the humidity may increase, providing conditions for the growth of molds and bacteria. This may cause the tobacco leaves to mildew and deteriorate, reducing the quality of the tobacco leaves; therefore, in view of the above problems, a tobacco leaf drying device is proposed to solve the above problems. Summary of the Utility Model

[0005] In view of one or more of the above defects or improvement requirements in the prior art, the utility model provides a tobacco leaf drying device, which has the advantages of being able to quickly dry the tobacco leaves, having higher drying efficiency, and being able to supplement the air volume for uniform drying.

[0006] To achieve the above object, the utility model provides a tobacco leaf drying device, including a bottom frame arranged in a rectangle;

[0007] Vertical frames are vertically arranged at the four corners of the bottom frame, and two drying frames are jointly supported on a plurality of the vertical frames;

[0008] Two groups of air supply components are also assembled at the upper end of the vertical frame. The two groups of air supply components respectively correspond to one of the drying racks and are arranged above the drying racks.

[0009] Among them, the air supply component includes four mounting seats arranged on the vertical frame. A lead screw is rotatably arranged between two adjacent mounting seats facing each other. Two sliding shaft sleeves are meshed with the outer parts of the two lead screws. Two mounting blocks are sleeved on the outer parts of the two sliding shaft sleeves. A fan member is installed between the two mounting blocks.

[0010] As a further improvement of the present utility model, two water filtering plates are supported on the bottom frame. A plurality of water filtering holes are formed in the water filtering plates. The two water filtering plates are respectively arranged below one of the drying racks.

[0011] As a further improvement of the present utility model, a plurality of trusses and reinforcing rib frames are further arranged between the plurality of vertical frames. The trusses and reinforcing rib frames are welded between two adjacent vertical frames.

[0012] As a further improvement of the present utility model, two rain shielding plates are supported at the top ends of the plurality of vertical frames. The rain shielding plates respectively correspond to one of the drying racks and are arranged above the drying racks.

[0013] As a further improvement of the present utility model, shaft seats are installed on the sides of two of the mounting seats. A bearing member is assembled in the shaft seats. One end of the lead screw is rotatably connected to the bearing member.

[0014] As a further improvement of the present utility model, reciprocating motors are further installed on the sides of two of the mounting seats.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment

[0023] Given by Figures 1-3 a tobacco leaf drying and curing device includes a chassis 1 arranged in a rectangle;

[0024] Vertical frames 3 are vertically arranged at the four corners of the chassis 1, and two drying racks 4 are jointly supported on several vertical frames 3;

[0025] Two sets of air supply components 7 are also assembled at the upper end of the vertical frame 3. The two sets of air supply components 7 respectively correspond to one of the drying racks 4 and are arranged above the drying rack 4.

[0026] Among them, the air supply component 7 includes four mounting seats 71 arranged on the vertical frame 3. A lead screw 74 is rotatably arranged between two adjacent mounting seats 71 facing each other. Slide shaft sleeves 75 are meshed with the outer parts of the two lead screws 74. Mounting blocks 76 are sleeved on the outer parts of the two slide shaft sleeves 75. A fan member 78 is installed between the two mounting blocks 76.

[0027] In this embodiment, during actual use, through the mutual movement and cooperation of multiple components in the air supply component 7, the two set mounting blocks 76 can drive the fan member 78 to move reciprocally above the drying rack 4; when the fan member 78 is connected to the power supply, at this time, through the reciprocating movement of the fan member 78, the air flow can be promoted and the tobacco leaves can be evenly blown, thereby helping to reduce the humidity difference between the tobacco leaves and enabling the tobacco leaves to be dried more evenly; even when the natural air volume in the external environment is low, through the auxiliary air supply of the fan member 78, the air flow speed can still be increased and the evaporation rate on the surface of the tobacco leaves can be improved. Compared with the direct hanging drying in the cited document, the drying device of the present application helps to accelerate the drying process of the tobacco leaves, shorten the drying time, and improve the production efficiency.

[0028] Specifically, referring to Figures 1-2 , two water filtering plates 2 are supported on the bottom frame 1. A number of water filtering holes 21 are opened on the water filtering plates 2. The two water filtering plates 2 are respectively arranged below one of the drying racks 4.

[0029] In this embodiment, during actual use, the vertical drying of the tobacco leaves can be realized through the arranged drying rack 4; the water filtering plate 2 arranged at the bottom of the drying rack 4 can filter the moisture generated during the drying of the tobacco leaves and prevent the tobacco leaves from falling to the ground during drying. Through the arranged water filtering plate 2, it is also easier to collect the debris generated during the drying of the tobacco leaves, thereby keeping the drying device of the present application clean and hygienic.

[0030] Specifically, referring to Figures 1-2 , a number of trusses 5 and reinforcing rib frames 6 are also arranged between a number of vertical frames 3. The trusses 5 and the reinforcing rib frames 6 are welded between two adjacent vertical frames 3.

[0031] In this embodiment, during actual use, the truss 5 and the reinforcing rib frame 6 are arranged to be cross-welded along the horizontal and vertical directions of the vertical frame 3, thereby improving the overall stability of the vertical frame 3. The truss 5 and the reinforcing rib frame 6 can form a firm framework around the frame body, thereby increasing the overall rigidity and anti-deformation ability of the drying apparatus of the present application, enabling the drying rack 4 to better withstand the influence of external loads and wind forces, effectively dispersing the weight and load of the tobacco leaves, reducing the pressure on individual support points, thus improving the overall bearing capacity of the drying rack 4 and reducing the risk of deformation or damage to the drying rack 4.

[0032] Specifically, referring to Figures 1-2 , two rain shields 8 are also supported and provided at the top ends of several vertical frames 3. The rain shields 8 respectively correspond to one of the drying racks 4 and are arranged above the drying racks 4.

[0033] In this embodiment, the rain shields 8 provided can be used to shield the drying racks 4. The rain shields 8 provided can effectively block rainwater and prevent rainwater from directly contacting the tobacco leaves. The shielding of rainwater is very important for the protection during the tobacco leaf drying process because rainwater may cause the tobacco leaves to become wet, moldy, or rotten, thereby reducing the quality and value of the tobacco leaves. At the same time, the rain shields 8 provided can help control the humidity and temperature during the drying process. In humid weather, the rain shields 8 can reduce the possibility of the tobacco leaves being splashed by rainwater and maintain the dryness of the tobacco leaves. In hot weather, the rain shields 8 can provide a certain shading effect and reduce the influence of the tobacco leaves being overexposed to the sun.

[0034] Specifically, referring to Figure 3 , shaft seats 73 are installed on the sides of two of the mounting seats 71. Bearing parts are assembled in the shaft seats 73, and one end of the lead screw 74 is rotatably connected to the bearing parts.

[0035] In this embodiment, the bearing parts in the shaft seats 73 provided can ensure the rotational stability of the lead screw 74. The rotational cooperation between the lead screw 74 and the bearing can provide a relatively high load-bearing capacity, and the design and selection of the bearing can be chosen according to actual needs to meet the required load-bearing capacity, thereby enabling the lead screw 74 to rotate smoothly.

[0036] Specifically, referring to Figure 3 , reciprocating motors 72 are also installed on the sides of two of the mounting seats 71. The adjacent reciprocating motors 72 and shaft seats 73 on the same side are arranged oppositely. The output end of the shaft seat 73 is connected to the other end of the lead screw 74. A positioning bolt 77 is threadedly connected to the mounting block 76. The fan member 78 is detachably assembled between the two mounting blocks 76 through the positioning bolt 77.

[0037] In this embodiment, through the movement of the mounting block 76, the fan member 78 disposed between the two mounting blocks 76 can perform reciprocating movement. By connecting a power source to the fan member 78, finally the fan member 78 can perform reciprocating movement above the drying rack 4 and realize the blowing of wind on the tobacco leaves. The positioning bolt 77 provided can also enable the installed fan member 78 to be quickly disassembled between the mounting blocks 76, thereby facilitating the user to install and repair.

[0038] The tobacco leaf drying apparatus of the present utility model:

[0039] First step: When the user dries the tobacco leaves, by hanging the tobacco leaves on the drying rack 4, the vertical drying of the tobacco leaves is realized through the drying rack 4; the water filtering plate 2 disposed at the bottom of the drying rack 4 can filter the moisture generated during the drying of the tobacco leaves, and at the same time prevent the tobacco leaves from falling to the ground during drying;

[0040] Second step: When the user needs to quickly dry the tobacco leaves, by connecting a power source to the two reciprocating motors 72, at this time, through the electrical drive of the reciprocating motors 72 and the rotational cooperation of the bearing members in the shaft seats 73, the provided lead screw 74 can rotate. At this time, through the installation limit between the two sliding shaft sleeves 75, the sliding shaft sleeve 75 engaged with the outside of the lead screw 74 will drive the mounting block 76 to perform reciprocating linear movement along the stroke range of the lead screw 74. Through the movement of the mounting block 76, the fan member 78 disposed between the two mounting blocks 76 can perform reciprocating movement. By connecting a power source to the fan member 78, finally the fan member 78 can perform reciprocating movement above the drying rack 4 and realize the blowing of wind on the tobacco leaves.

[0041] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
