Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that all the directional indicators (such as up, down, left, right, front, and rear …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly. In addition, the descriptions related to "preferred", "less preferred", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "preferred" or "less preferred" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 4, the invention provides an automatic belt cutting device for a tobacco leaf packaging box, which comprises a frame 1, wherein a conveying line capable of conveying the packaging box 2 forwards is arranged on the frame 1, a guide limiting device capable of limiting the positions of the left side and the right side of the packaging box 2 is arranged on the conveying line, and a cutting mechanism 5 capable of cutting a binding belt 21 and a feed driver 4 capable of driving the cutting mechanism 5 to move left and right are arranged on one side of the conveying line.

Set up devices such as photoelectric sensor or travel switch on the frame 1 to cut the right side that mechanism 5 is located the transfer chain as the example, when the packing box 2 that is equipped with the tobacco leaf moved to the work area who cuts mechanism 5, photoelectric sensor or travel switch detected the position of packing box 2, gave central control unit with position signal transmission, central control unit gives out the instruction, makes the work of feed driver 4, and the drive cuts mechanism 5 and moves left with the feed, cuts the back of the sword of bandage 21 on the packing box 2. After cutting the band 21, the package case 2 is further moved forward, and the cut band 21 is grasped, so that the band 21 can be easily detached from the package case 2.
