Description

Technical Field

[0001] The invention relates to the technical field of tobacco production, and in particular to a tobacco leaf intelligent auxiliary material uniformization system. Background Art

[0002] Tobacco excipients refer to various substances added during tobacco processing to improve the flavor, taste and burning characteristics of tobacco leaves. Common excipients in tobacco leaves include spices, sweeteners, humectants and fermentation aids. During the tobacco processing, excipient addition refers to the uniform addition of various excipients (such as spices, sweeteners and humectants) to tobacco leaves to improve the taste, aroma and burning performance of tobacco leaves. This process is crucial to ensuring the quality of the final product.

[0003] However, in the processing of tobacco auxiliary materials, tobacco leaves are usually piled up with high in the middle and low at both ends due to the gravity of the conveyor belt. This uneven distribution causes the tobacco leaves to fall too concentrated on the conveyor belt, thus affecting the subsequent processing effect of the tobacco leaves, forcing the operators to manually spread and flatten the tobacco leaves, thus affecting the overall material distribution efficiency, resulting in waste of tobacco leaves and increased production costs. Summary of the invention

[0004] The purpose of the present invention is to provide a tobacco leaf intelligent auxiliary material uniformity system to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a tobacco leaf intelligent auxiliary material uniformity system, comprising an equipment platform, a first shell is installed on the top of the equipment platform, a second shell is installed on the bottom of the equipment platform, a primary conveyor belt is installed inside the first shell, a secondary conveyor belt is installed inside the second shell, a third shell is embedded on the equipment platform, a plurality of equidistantly arranged electric material dividing rollers are installed on the inner wall of the third shell, the electric material dividing rollers are located at the bottom of the primary conveyor belt and the top of the secondary conveyor belt, a material flattener is fixedly connected to one side of the equipment platform, and the material flattener is located on the top of the secondary conveyor belt.

[0006] Preferably, air nozzles are installed on the inner walls on both sides of the third shell, and the air outlets of the air nozzles face the ends of the electric material distribution rollers.

[0007] Preferably, a CCD camera is installed on one side of the material flattener.

[0008] Preferably, a feed rail is installed on the top of the first shell, and a tobacco conveyor belt is installed inside the feed rail.

[0009] Preferably, a PLC controller is installed on one side of the first shell, and the PLC controller is connected to the electric control ends of the primary conveyor belt, the secondary conveyor belt, the CCD camera and the electric material distribution roller through wires.

[0010] Preferably, the inner walls on both sides of the third shell are provided with a plurality of equally spaced mounting holes, and both ends of the electric material dividing roller are mounted inside the mounting holes.

[0011] Preferably, a fence is installed at the top edge of the equipment platform.

[0012] Preferably, a collecting tank is provided at the bottom of the second shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention conveys tobacco leaves to the primary conveyor belt through a tobacco conveyor belt, and the materials fall onto an electric material distribution roller. The rotation speed of each roller is individually adjusted by a PLC controller, and the speed difference can make the tobacco leaves falling on the roller body be distributed to both sides. After the electric material distribution roller evenly distributes the tobacco leaves, the tobacco leaves fall onto the secondary conveyor belt.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1 An embodiment of the present invention provides a tobacco leaf intelligent auxiliary material uniformity system, including: an equipment platform 1.

[0024] In this embodiment, Figure 1-Figure 5 As shown, a first shell 3 is installed on the top of the equipment platform 1, a second shell 10 is installed on the bottom of the equipment platform 1, a primary conveyor belt 4 is installed inside the first shell 3, a secondary conveyor belt 11 is installed inside the second shell 10, a third shell 13 is embedded on the equipment platform 1, a plurality of equidistantly arranged electric dividing rollers 8 are installed on the inner wall of the third shell 13, the electric dividing rollers 8 are located at the bottom of the primary conveyor belt 4 and the top of the secondary conveyor belt 11, a feed rail 5 is installed on the top of the first shell 3, and a tobacco conveyor belt 6 is installed inside the feed rail 5.

[0025] When in use, the tobacco leaves are conveyed to the primary conveyor belt 4 through the tobacco conveyor belt 6 in the feed track 5. The primary conveyor belt 4 conveys the tobacco leaves to the bottom of its feeding port and falls onto the electric dividing roller 8. The rotation speed of each electric dividing roller 8 is different, so that different speed differences are generated between different electric dividing rollers 8. The tobacco leaves that fall on the electric dividing roller 8 can be divided to both sides of the falling point due to the different speed differences between different electric dividing rollers 8, and the gaps between multiple electric dividing rollers 8 are used to evenly distribute the tobacco leaves, thereby achieving the purpose of quickly and evenly distributing the material. The tobacco leaves that are evenly distributed by the electric dividing roller 8 fall onto the secondary conveyor belt 11.

[0026] Among them, Figure 4 and Figure 5As shown, a material flattener 12 is fixedly connected to one side of the equipment platform 1, and the material flattener 12 is located on the top of the secondary conveyor belt 11. A CCD camera 16 is installed on one side of the material flattener 12. A PLC controller 7 is installed on one side of the first shell 3. The PLC controller 7 is connected to the electrical control ends of the primary conveyor belt 4, the secondary conveyor belt 11, the CCD camera 16 and the electric material dividing roller 8 through wires.

[0027] Furthermore, a collecting trough 2 is provided at the bottom of the second shell 10, and the tobacco leaves transported by the secondary conveyor belt 11 can fall into the collecting trough 2 for subsequent processing.

[0028] When the PLC controller 7 is in use, the rotation speed of each electric material distribution roller 8 is individually controlled by the PLC controller 7. At the same time, the PLC controller 7 can receive the image signal of the CCD camera 16, and identify the edges and contours of the tobacco leaves in the conveying state through the image processing algorithm, or extract and identify the tobacco leaf area in the image based on the color segmentation technology of the tobacco leaves in the picture. The PLC controller 7 adjusts and controls the running speed of the primary conveyor belt 4 or the electric material distribution roller 8 according to the number of tobacco leaves identified.

[0029] Furthermore, the inner walls on both sides of the third shell 13 are provided with a plurality of equally spaced mounting holes 15 , and both ends of the electric material dividing roller 8 are mounted inside the mounting holes 15 . The electric material dividing roller 8 can be installed in different mounting holes 15 .

[0030] like Figure 3 As shown, air nozzles 14 are installed on the inner walls of both sides of the third shell 13, and the air outlet of the air nozzle 14 faces the end of the electric material dividing roller 8. The air inlet of the air nozzle 14 blows air to the end of the electric material dividing roller 8 by connecting to an external air pump, thereby completing the blowing and cleaning work of the residual leaves at the end of the roller body.

[0031] Specifically, a fence 9 is installed at the top edge of the equipment platform 1 , and the fence 9 can play a protective role for the staff walking on the equipment platform 1 .

[0032] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when the present invention is used, tobacco leaves are conveyed to the primary conveyor belt 4 through the tobacco conveyor belt 6, and the primary conveyor belt 4 conveys the tobacco leaves to the bottom of its feeding port and falls onto the electric material dividing roller 8. The rotation speed of each electric material dividing roller 8 is individually controlled by the PLC controller 7, and different speed differences are generated between different electric material dividing rollers 8. After the material falls onto the primary conveyor belt 4, it will present a situation of high in the middle and low at both ends, and the tobacco leaves falling on the electric material dividing roller 8 can have different speed differences between different electric material dividing rollers 8, so that the material is divided to both sides of the falling point, and the gaps between multiple electric material dividing rollers 8 are used to evenly distribute the tobacco leaves, thereby achieving the purpose of quickly and evenly distributing the material, and the tobacco leaves evenly dispersed by the electric material dividing roller 8 fall onto the secondary conveyor belt 11.

[0033] To ensure that the tobacco leaves are further evenly distributed, a material flattener 12 is provided on the top of the secondary conveyor belt 11. A gap is left between the material flattener 12 and the top of the secondary conveyor belt 11, so that the tobacco leaves can pass through the gap for the final flattening process when passing through the material flattener 12, and the CCD camera 16 takes pictures for feedback, and feeds back the picture signal in real time to the PLC controller 7. The PLC controller 7 adjusts and controls the running speed of the primary conveyor belt 4 or the electric material distribution roller 8 according to the amount of tobacco leaves passing through.

[0034] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
