Description

Technical Field

[0001] The present invention belongs to the field of tobacco shred flattening and impurity removing devices, and particularly relates to a tobacco shred flattening and impurity removing device. Background Art

[0002] Currently, tobacco shred impurity removal mainly relies on manual operation. In the prior art, generally, an unflattened tobacco shred is conveyed to a relatively wide area by a belt conveyor, and then manually spread out. Visible impurities in the tobacco shred are inspected and picked out manually. For impurities such as hemp threads, a nylon sticky tape is used, and the nylon sticky tape needs to be cleaned manually regularly. Another common method is to convey the tobacco shred by a belt conveyor, and manually flatten and pick out impurities. However, these manual operation methods have obvious drawbacks. On the one hand, the efficiency of manually picking out impurities is relatively low, which is difficult to meet the requirements of large-scale production. On the other hand, the labor cost is relatively high, increasing the production cost of the enterprise, and is not conducive to the efficient production and economic benefit improvement of the enterprise.

[0034] Working principle:

[0035] The cut tobacco is conveyed by the flat belt of the cut tobacco conveying belt component. The driving motor drives the driving shaft to rotate, and then drives the flat belt to run, and the cut tobacco is conveyed forward on the belt. When the cut tobacco reaches the leveling mechanism component, the motor drives the driving shaft, and drives the screw rod to rotate through the transmission of the first gear and the second gear. The rakes on the screw rod level the cut tobacco with poor fluidity into a certain thickness, and the leveling thickness and width can be changed according to actual requirements.

[0036] The leveled cut tobacco continues to be conveyed to the CCD image acquisition component. The CCD image acquisition camera in this component takes pictures and identifies the cut tobacco under the support of the fixed frame. When impurities are identified in the cut tobacco, the CCD image acquisition component generates the coordinate information of the impurities and feeds it back to the sundry removing component.

[0037] The robot (which can be a multi-axis robot or a three-coordinate manipulator, etc.) in the sundry removing component quickly moves to the specified position according to the received coordinate information, the Z-axis descends, uses the pneumatic gripper to grab the sundries on the conveyor belt, then the Z-axis ascends, and the robot returns to the origin and throws the sundries at a suitable position. During the whole process, the conveying speed of the cut tobacco conveying belt component, the identification speed of the CCD image acquisition component, and the running speed of the robot match each other to ensure that the device efficiently and accurately completes the work of leveling and removing impurities from the cut tobacco.

[0038] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical fields can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention, and the patent protection scope of the present invention shall be defined by the claims.
