Description

Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, and in particular to a detection device for the self-connected joint of the paper roll of the YJ17 type cigarette forming machine. Background Technology

[0002] The manufacturing process of cigarette packs involves rolling tobacco into rolls. In this process, the paper roll, as the base material for cigarettes, plays a crucial role. There are two types of joints in the paper roll material: one is internal joints formed during manufacturing, and the other is joints created when changing rolls of paper during cigarette production using materials such as tape. This process generates numerous internal and external joints. If these joints are not removed promptly, they will be rolled into the cigarette during the rolling process, resulting in defective cigarettes. To ensure the quality of the finished cigarettes, it is necessary to install detection devices on the cigarette rolling equipment to monitor the paper rolls in real time. Once a joint is detected, the device sends a rejection signal to the control system of the cigarette rolling equipment, thereby promptly removing the corresponding cigarette. In practical applications, the detection device typically requires the following technologies:

[0003] 1. High-sensitivity sensing: This is the key to detecting paper roll joints. Optical sensors have strong imaging or light detection functions, while inductive sensors are sensitive to magnetic permeability. Optical sensors can detect changes in reflection and refraction with high accuracy, providing a basis for judgment.

[0004] 2. Intelligent signal processing: Due to the complexity and noise of the original signal, it is important to use algorithms such as wavelet analysis to remove noise, extract features and identify patterns, improve accuracy and intelligence, reduce the false judgment rate and ensure stable operation;

[0005] 3. Rapid response control: Essential for high-speed cigarette production, the control unit has excellent performance to ensure continuous and efficient production;

[0006] 4. Reliable anti-interference: There is a lot of interference in the production site, and the testing device needs this technology. In terms of hardware, it is shielded cable connection and electromagnetic shielding. In terms of software, it is data verification and repair, such as CRC verification, to ensure data accuracy and normal operation of the device.

[0007] Currently, cigarette rolling machines typically use ordinary through-beam photoelectric sensors to detect paper roll joints. This method utilizes the penetrability of light to identify and reject joints. During production, this device can accurately identify and reject paper roll joints. Existing detection devices for paper roll joints on the YJ17 type rolling and forming machine have several important functions. In terms of quality control, they can promptly and accurately detect paper roll joints, preventing defective joints from entering the cigarette rolling process. This avoids quality problems such as loose ends, empty ends, and air leaks caused by poor joints, effectively improving the quality stability and pass rate of cigarette products and enhancing the brand. In terms of production assurance, the rapid response and collaborative operation with the rolling and forming machine can reduce equipment downtime caused by untimely handling of paper roll joints, improve production efficiency, reduce production costs, and ensure the continuity and smoothness of cigarette production. In terms of production management, the joint detection data recorded by the detection device can be used for statistical analysis of the production process, such as the frequency and location distribution of joints, providing data support for optimizing paper roll procurement, storage and usage management. At the same time, it helps to discover potential problems in the production process, making it easier to take timely improvement measures and enhance the overall management level and competitiveness of cigarette production enterprises.

[0008] However, the above method has a significant hardware structural problem: for paper rolls with splices that are narrower and thicker than the roll-changing connector, the device often misses some splices. Furthermore, the device cannot adjust the detection accuracy, making it impossible to completely solve the problem of missing splices, ultimately affecting cigarette quality. This application proposes a solution to this problem. The device combines a high-precision through-beam fiber optic sensor with a fiber optic signal amplifier to achieve accurate identification of paper roll splices, greatly reducing missed detections and ensuring effective removal of splices during cigarette production.
