Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packet slicing control, and more specifically, to a cigarette packet slicing and conveying system with length detection. Background Art

[0002] During the production process of cigarette packets, cigarette packet slicing machines are usually used in the workshop to cut large packets of tobacco into thin slices. The existing slicing machines send cigarette packets to the cutting position through a conveyor belt. The cigarette packets stop after being blocked by a baffle at the end of the conveyor belt, and then the cutting knife starts to cut. However, due to the differences in the lengths of cigarette packets, this method leads to the problem that the thicknesses of the cut cigarette packets are inconsistent. After the "three-knife and four-piece" cutting, the inconsistent thickness of the cigarette packets results in inconsistent looseness in the drums of the next process, which affects the consistency and quality of the products. Traditional slicing machines do not have the function of detecting and adjusting the length of cigarette packets, which makes it impossible for operators to adjust the position of the cutting knife according to the actual length of the cigarette packets, resulting in difficulty in maintaining the consistency of the thickness of the cut cigarette slices. This not only affects the quality of the products but also increases the complexity and cost of production. Therefore, it is of great significance to detect the length of the conveyed cigarette packets and adjust the position of the cutting knife according to the length of the cigarette packets to ensure the consistency of the thickness of the cut cigarette slices.

[0033] Such as Figure 1 and Figure 2As shown in the figure, a cigarette packet slicing and conveying system with length detection includes: a PLC programmable controller, an opposed photoelectric tube 1, and a speed sensor 2. A set of the opposed photoelectric tubes 1 is arranged on both sides of the cigarette packet conveyor belt at a set position for detecting the conveying duration of the cigarette packet passing through the set position. The speed sensor 2 is arranged on the side of the conveyor belt 3 for detecting the conveyor belt speed of the conveyor belt. The PLC programmable controller is respectively signal-connected to the opposed photoelectric tube and the speed sensor. The PLC programmable controller calculates the corresponding cigarette packet length according to the conveying duration and the conveyor belt speed, and reports the cigarette packet length, so that the slicing machine slices the cigarette packet evenly according to the cigarette packet length.

[0034] In practical applications, the opposed photoelectric tube is installed at the one-fifth position on the left side of the conveyor belt for detecting the length of the cigarette packet. When the opposed photoelectric is blocked, the PLC programmable controller starts timing. When the blockage is released, it is regarded as the end of a timing cycle.

By multiplying the blocking time of the opposed photoelectric by the current conveyor belt speed, the current length of the cigarette packet can be obtained. This system detects the length of the cigarette packet in real time through the opposed photoelectric and transmits the data to the PLC. The PLC accurately controls the subsequent slicing process accordingly, ensuring the accuracy and consistency of each cigarette packet cutting. This precise length detection and control system eliminates the problem of uneven cutting caused by the difference in cigarette packet length and improves the product quality.

[0038] This system further includes: a driving device; the driving device is drivingly connected to the conveyor belt, and the driving device is signal-connected to the PLC programmable controller. The PLC programmable controller controls the operation of the driving device to control the timing of the conveyor belt for conveying the cigarette packet.

[0039] Further, the driving device includes: a driving motor and a speed reducer; a rotating shaft of the driving motor is drivingly connected to the speed reducer, the speed reducer is drivingly connected to the conveyor belt, and the speed reducer is configured to convert the rotational speed of the driving motor into the rotational speed required by the conveyor belt.
