Description

Technical Field

[0001] This utility model relates to the field of belt scale calibration technology, and specifically to an electronic belt scale calibration device. Background Technology

[0002] Electronic belt scales are widely used in the feeding and blending / flavoring sections of cigarette manufacturing workshops. They automatically, quickly, continuously, and cumulatively weigh bulk materials such as tobacco leaves or shredded tobacco. As a crucial measuring device in the "blending and flavoring ratio measurement" process of the cigarette manufacturing workshop, electronic belt scales play a key role in the cigarette manufacturing process. However, after long-term operation, electronic belt scales are prone to problems such as insufficient belt tension, frequent belt deviation, wear of idler rollers, and material sticking to the idler rollers, affecting the accuracy of the measurement. Therefore, it is necessary to calibrate electronic belt scales regularly to ensure their measurement accuracy. The accuracy and reliability of the calibration method directly affect the judgment of the calibration results of electronic belt scales. Currently, the calibration method for electronic belt scales is manual, requiring four technicians to work together. Weights are placed on the belt scale, and the electronic belt scale accumulates the weights. During this process, the manual staff continuously place, retrieve, and pass the weights. Once the accumulated weight reaches 100kg, the addition of weights is stopped. Each electronic belt scale needs to be calibrated at two flow points, which means two rounds of weights need to be added. This method is labor-intensive and has problems such as low calibration efficiency, high manpower requirements, high labor intensity, and high professional requirements for calibration personnel.

[0020] Please see Figures 1 to 14 An embodiment of the present invention provides an electronic belt scale calibration device, comprising a protective component 4, a recovery component 1, a transfer component 3, and a storage component 2 for storing weights 5.

[0021] Here, the storage unit 2 has dustproof and sealing properties, protecting the weight 5 when it is placed inside. It may also include controllers for separately controlling the recovery unit 1, the transfer unit 3, and the storage unit 2. The controllers are programmed to perform calibration by placing the device in a position matching the electronic belt scale, acquiring the belt speed, and controlling the recovery unit 1, storage unit 2, and transfer unit 3 according to the belt speed. This controls the release interval of the weight 5, and the calibration position is set within the belt width via a program, achieving intelligent, multi-point, flexible, and evenly distributed release of the weight 5. After dynamic weighing, the weight 5 is recovered via the recovery unit 1, ensuring a gentle recovery action. The internal transmission mechanism automatically performs multiple repetitive actions, truly realizing intelligent, automated, and standardized operation throughout the belt calibration process. This reduces the intensity and uncertainty of manual operation, avoids the load caused by manually grasping the weight 5 affecting measurement stability and accuracy, and makes the calibration results more accurate and stable. The left and right sides of the recycling shell 12 are provided with recycling through holes through which the weight 5 can pass; the left and right sides of the storage shell 25 are provided with storage through holes through which the weight 5 can pass; the left and right sides of the conveying shell 32 are provided with transfer through holes through which the weight 5 can pass.

[0022] Specifically, storage unit 2 can achieve dustproof sealing for 10 standard weights 5.

The controller controls the recovery unit 1, transfer unit 3, and storage unit 2 according to the program, making it widely adaptable to electronic belt scale control systems from different manufacturers in the industry. Functionally, it allows for setting different calibration positions within the belt width range, enabling multi-point even distribution and automatic repeated measurement calibration, minimizing errors at the four corners of the belt scale frame and sensors, and achieving full coverage calibration of sensor positions. This application realizes the intelligent, automated, and standardized calibration process of the electronic belt scale, achieving high precision and high stability in calibration work. Compared with manual calibration, it further improves the stability and repeatability of the calibration process and can promptly detect and overcome measurement errors at the four corners of the belt scale, thereby ensuring the stability and accuracy of the wire-making process control. It effectively improves the calibration efficiency of the electronic belt scale while reducing manual labor intensity. The controller may include control hardware and software. The control hardware includes a PLC, relays, circuit breakers, etc., while the control software is an intelligent calibration control program for electronic belt scales. It is widely compatible with electronic belt scale control systems from different manufacturers in the industry, seamlessly integrating into existing electronic belt scale control interfaces to achieve fully automated operation without affecting the original functions of the electronic belt scale. This truly realizes the intelligent, automated, and standardized completion of the entire belt calibration process, with a measurement repeatability standard deviation of <0.02kg. The recovery component 1 is located upstream of the weight 5's flow direction. Through a zero-speed difference and zero-impact recovery action, it recovers the weight 5 from the electronic belt scale, avoiding the load caused by manual handling of the weight 5 affecting measurement stability and accuracy, thus automating and standardizing the weight 5 recovery process. The transfer component 3 is located downstream of the weight 5's flow direction, used to accurately release the weight 5 onto the belt scale. It can intelligently and flexibly distribute the weight 5 at different calibration positions within the belt width range, with a weight 5 release cycle of 5 seconds per weight.

[0036] Specifically, the translation motor 44 drives the first translation rotating wheel 46, which in turn drives the translation synchronous belt 47.

The recovery component 1, storage component 2, and transfer component 3 are all connected to the moving seat 21, thus enabling the movement of the recovery component 1, storage component 2, and transfer component 3.

[0039] The storage component 2 may also include a storage guide bar 219 disposed on the inner side wall of the storage housing 25, the storage guide bar 219 being used to limit the side of the weight 5.

[0040] Specifically, there are two symmetrically arranged first storage synchronization belts 218, with the weight 5 placed between the two first storage synchronization belts 218.

[0041] Specifically, this application utilizes a transfer component 3 to achieve flexible release of the weight 5. During the flexible release process, the weight 5 can automatically and accurately track the belt speed. The transfer component 3 controls the weight 5 to run in the same direction and at the same speed as the electronic belt scale, ensuring zero speed difference and zero impact during the release process. The release interval of the weight 5 is precisely controlled through a closed-loop belt speed control. The weight 5 is also flexibly retrieved using a recovery component 1. The recovery component 1 controls its belt to run in the same direction and at the same speed as the electronic belt scale, ensuring a gentle retrieval action with zero speed difference and zero impact, avoiding the impact of manual handling of the weight 5 on measurement stability and accuracy. Furthermore, this application is designed based on the dimensions and available installation space and location of existing mainstream electronic belt scales, avoiding interference and adverse effects on the operation and maintenance of existing equipment. It also optimizes the installation and connection methods, providing a connection structure for rapid deployment and retrieval, maintaining long-term stability and reliability without maintenance. Through a seamless design of the control system and operating scheme, it integrates intelligent automatic calibration functions without affecting the original electronic belt scale control program. Addressing the shortcoming of fully automated calibration for electronic belt scales, this application achieves intelligent, automated, and standardized calibration processes, further improving the stability and repeatability of the calibration process compared to manual calibration, thereby ensuring the stability and accuracy of the wire-making process control. Simultaneously, it effectively improves the calibration efficiency of electronic belt scales, saves human resource costs, and reduces manual labor intensity. Furthermore, through its adaptable design, the device can be applied to electronic belt scales from different manufacturers in both hardware and software, demonstrating broad potential for widespread adoption within the industry.
