Description

Technical Field

[0001] This utility model belongs to the technical field of tube making and tape splicing equipment, specifically relating to an intelligent automatic tape splicing platform for a tube making machine. Background Technology

[0002] In the steel processing and pipe manufacturing industry, steel coil pipe making is the core process for achieving continuous steel processing. It is widely used in petrochemical, municipal engineering and other fields. It uses steel coils as raw materials and produces steel pipes through processes such as uncoiling, leveling, forming and welding. Currently, the splicing process of steel coil pipe making production lines generally relies on manual operation: when the current steel coil is about to run out, the operator needs to stop the machine, manually pull the new steel coil head to the splicing position, adjust the alignment by visual inspection and experience, then fix it by welding, and finally restart the production line. The manual splicing method leads to high labor costs, and the existing manual splicing method is prone to poor splicing alignment accuracy, resulting in poor splicing effect and increased production costs. In addition, frequent machine stops and starts during the splicing process will reduce production efficiency.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses an automatic welding system for butt welding of rolled steel plates [201510199153.8], which includes a conductive copper plate located on a steel plate conveyor belt. A steel plate detection switch is provided on the front side of the conductive copper plate and is connected to a control system. Front and rear pressure plates are provided above the conductive copper plate, and a welding position detection device is provided above the conveyor belt. An automatic welding torch is provided on a three-dimensional moving mechanism. The welding position detection device includes a rotating shaft provided on a lifting frame. A rotary encoder is connected to the rotating shaft and is connected to the control system. The upper end of a telescopic rod is fixedly connected to the rotating shaft, and a contact with an arc-shaped bottom surface is fixedly connected to the lower end of the telescopic rod.

[0004] The above solution has solved the problems of poor splicing effect and high labor cost to a certain extent. However, the solution still has many shortcomings. For example, it still uses the method of stopping the machine to splice the belt, resulting in low production efficiency. Summary of the Invention
