Description

Technical Field

[0001] This invention relates to the field of industrial machinery production technology, and more specifically to a visual recognition impurity removal machine for tobacco processing. Background Technology

[0002] Currently, the requirements for the purity of tobacco are constantly increasing. Because tobacco leaves undergo a long process from planting and harvesting to processing, impurities such as paper scraps, cloth pieces, plastic, and hemp rope are unavoidable. Currently, the traditional methods for controlling non-tobacco impurities in China include the following:

[0003] Manual impurity removal involves manually separating non-tobacco impurities from the conveyor belt during the tobacco preparation process by controlling the conveyor belt speed. This method can remove most impurities, but it has low production efficiency.

[0004] A drum-type sand screening machine separates sand and small particles from tobacco leaves under centrifugal force as the drum rotates. This method effectively removes dust and small particles from tobacco leaves, but it also increases the breakage rate of the tobacco shreds.

[0005] Metal detection involves designing a system to detect specific metallic impurities in tobacco leaves or shredded tobacco. When the system detects impure tobacco shreds passing through, it issues a control command to transport the shredded tobacco to a designated processing point for further manual handling. This method offers limited impurity removal and is relatively costly.

[0006] The hemp fiber removal machine mainly utilizes the difference in adhesive properties between tobacco leaves and non-tobacco impurities such as hemp fibers and hair. It uses an adhesive material on the surface of the hemp fiber removal roller to adsorb these impurities, thus achieving separation. The disadvantage of this method is that manual cleaning of the hemp fibers and hair from the adhesive material surface is required.

[0007] Problems with existing methods: poor universality. Currently, the impurity removal machinery used or designed on tobacco production lines for impure tobacco only targets specific impurities in the tobacco, such as metals and hemp fibers, or it is a combination of multiple impurity removal modules. Such impurity removal machinery can only target specific tobacco impurities and has poor adaptability to ordinary impure tobacco, resulting in low impurity removal efficiency. Low combined utilization rate. Currently, tobacco production enterprises carry out the two processes of tobacco clump control and tobacco impurity removal separately. Loose tobacco clumps mostly occur in tobacco quality inspection and tobacco discharge stages. The combined utilization rate of tobacco clump control and tobacco impurity removal processes is low.

[0008] Therefore, how to provide a visual identification impurity removal machine in the tobacco processing process that can quickly and accurately expose, detect and identify non-tobacco impurities contained in tobacco and remove them is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0009] In view of this, the present invention provides a visual identification impurity removal machine for tobacco processing, which aims to solve one of the problems in the background art mentioned above, and can quickly and accurately expose, detect and identify non-tobacco impurities contained in tobacco and remove them.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A visual recognition impurity removal machine for tobacco processing includes:

[0012] The impurity removal module includes a first connector, a first motor, and a first movable baffle. The first connector is located at the end of the second conveyor belt, the first motor is mounted on the first connector, and the first connector has a first drop groove. The first movable baffle is rotatably mounted in the first drop groove. By rotating the first movable baffle with the first motor, the area containing impurities in the tobacco shreds is dropped from the second conveyor belt into the first drop groove, while the tobacco shreds without impurities continue to be conveyed forward from above the first connector and the first movable baffle.

[0013] Furthermore, the first dispersing component includes a mounting frame and star rollers. The mounting frame is positioned above the first conveyor belt, and multiple star rollers are provided. All multiple star rollers are horizontally positioned within the mounting frame to disperse the tobacco shreds.

[0014] Furthermore, it also includes a third conveyor belt, which is connected to the end of the first connector away from the second conveyor belt, and the third conveyor belt continues to convey the tobacco shreds that do not contain impurities forward.

[0015] Furthermore, it also includes a fourth conveyor belt, one end of which is located in the air chamber, and the other end of which extends out of the air chamber. The fourth conveyor belt is located below the second conveyor belt, and a second dispersing component is provided above the fourth conveyor belt. When the fan blows the tobacco towards the second conveyor belt, the tobacco that falls off falls onto the fourth conveyor belt and is dispersed by the second dispersing component before continuing to be conveyed.

[0016] Furthermore, it also includes a second identification module, which is located above the fourth conveyor belt and identifies the area of ​​scattered tobacco on the fourth conveyor belt.

[0017] Furthermore, it also includes a second impurity removal module, which is located at the end of the fourth conveyor belt away from the air chamber. The second impurity removal module includes a second connector, a second motor, and a second movable baffle. The second connector is located at the end of the fourth conveyor belt, and the second motor is mounted on the second connector. The second connector has a second drop groove, and the second movable baffle is rotatably mounted in the second drop groove. By rotating the second movable baffle with the second motor, the area of ​​tobacco containing impurities is dropped from the fourth conveyor belt into the second drop groove, while tobacco without impurities continues to be conveyed forward from above the second connector and the second movable baffle.

[0018] Furthermore, it also includes a fifth conveyor belt, which is connected to the end of the second connector away from the fourth conveyor belt, and the fifth conveyor belt continues to convey the tobacco shreds that do not contain impurities forward.

[0019] Furthermore, the top of the air chamber is provided with guide plates, two of which are arranged at an angle relative to each other and both are located above the first conveyor belt.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a visual recognition impurity removal machine in the tobacco processing process. The tobacco is broken up by a first dispersing component and then conveyed by a first conveyor belt. A fan blows the tobacco falling from the end of the first conveyor belt onto a second conveyor belt. A first recognition module identifies the area of ​​tobacco containing impurities conveyed on the second conveyor belt. A first motor rotates a first movable baffle to drop the area of ​​tobacco containing impurities from the second conveyor belt into a first drop trough. Tobacco without impurities continues to be conveyed forward from above the first connector and the first movable baffle. Attached Figure Description

[0050] Specific usage process

[0051] First, tobacco containing impurities is placed into the first dispersing component 2, where it is dispersed. The dispersed tobacco is then conveyed by the first conveyor belt 3 to the air chamber 5, where a fan 6 blows and spreads it out. The tobacco floats in the upper space of the air chamber 5 and, under the influence of gravity and guided by the inclined guide plate 26 inside the air chamber 5, is sent to the second conveyor belt 7, which continues to convey the tobacco.

[0052] During the process of the blower 6 blowing the tobacco towards the second conveyor belt 7, due to the different weights of the tobacco, the larger and heavier tobacco cannot be blown towards the second conveyor belt 7 by the blower 6. Some of the fallen tobacco falls onto the fourth conveyor belt 17 and is dispersed by the second dispersing component 18 before being conveyed by the fourth conveyor belt 17.

[0053] The reflector 29 and light source provider 30 of the first identification module 8 illuminate the tobacco on the second conveyor belt 7, and the reflector 29 and light source provider 30 of the second identification module 19 illuminate the tobacco on the fourth conveyor belt 17. The camera 28 of the first identification module 8 identifies the tobacco on the second conveyor belt 7, and the camera 28 of the second identification module 19 identifies the tobacco on the fourth conveyor belt 17.

[0054] By setting the first motor 11 to rotate the first movable baffle 12, the area of ​​tobacco containing impurities falls from the second conveyor belt 7 into the first drop trough 13, while the tobacco without impurities continues to be conveyed forward from above the first connector 10 and the first movable baffle 12.

[0055] The second motor 22 rotates the second movable baffle 23 to drop the tobacco containing impurities from the fourth conveyor belt into the second drop trough 24, while the tobacco without impurities continues to be conveyed forward from above the second connector 21 and the second movable baffle 23.

[0056] Among them, the tobacco shreds without impurities that are conveyed from the second conveyor belt 7 are conveyed forward by the third conveyor belt 16, and the tobacco shreds without impurities that are conveyed from the fourth conveyor belt 17 are conveyed forward by the fifth conveyor belt 25.

[0057] The tobacco containing impurities that falls from the drop trough 13 on the second conveyor belt 7 and the fourth conveyor belt 17 falls onto two impurity conveyor belts 31. The tobacco containing impurities is manually sorted out, and only the pure tobacco is on the impurity conveyor belts 31. The pure tobacco is then conveyed by the impurity conveyor belts 31 to the receiving trough 26 for collection.
