AI Technical Summary
[0003]现有的钢印装置存在以下技术问题，以G.D.S1000软包卷烟包装机的生产线为例，该生产线采用24小时连续运转模式，依据生产班次，单日需更换钢印至少三次，而在更换钢印时，需经历拆卸支承辊、分离钢印装置主体、拆解固定板等多道工序，拆装流程极为繁琐，耗时冗长，严重影响生产线的连续运转节奏；其次，由于钢印字码需印刷在铝箔纸侧边这一狭窄区域，对字码与铝箔纸的相对位置精度提出了极高要求，现有的钢印装置缺乏稳定的定位与调节机制，在高速生产过程中极易因微小的位置偏差导致铝箔纸输送时出现歪斜，进而在印刷过程中造成钢印标识模糊、错误等问题，造成印刷质量低下的问题
[0020]This utility model proposes a steel stamping device for printing markings on a workpiece. The steel stamping device includes a support assembly and a roller assembly. The support assembly includes a support base and a fixed bracket. The connecting end of the fixed bracket is rotatably mounted on the support base, allowing the movable end of the fixed bracket to move closer to or further away from the support base, thus enabling the fixed bracket to have a closed state and an open state. The roller assembly includes an input roller, a character roller, and an output roller. The input roller is rotatably mounted on the support base for introducing the workpiece, and the output roller is rotatably mounted on the support base for leading out the workpiece. Limiting protrusions are provided at both ends of the output roller, allowing the workpiece to pass between the two limiting protrusions. The character roller includes a support shaft and a rotating sleeve. The rotating sleeve is rotatably mounted on the outer peripheral sidewall of the support shaft. The support shaft is detachably connected to the fixed bracket. When the fixed bracket is in the closed state, the workpiece can be sequentially wound around the input roller, character roller, and output roller to print markings on the workpiece. When the fixed bracket is in the open state, the character roller can be detached from the fixed bracket. First, the support assembly consists of a support base and a fixed bracket. The connecting end of the fixed bracket is rotatably mounted on the support base, allowing the movable end to open and close flexibly to be in a closed or open state. In the closed state, the movable end of the fixed bracket is close to the support base, forming a stable connecting frame. In the open state, the movable end is away from the support base, exposing the installation space. At this time, the support shaft can be removed from the fixed bracket, and the entire character roller can be removed and replaced. This process does not require multiple disassembly steps, achieving quick loading and unloading. Second, the output roller has limit protrusions at both ends. The workpiece to be printed passes between the two protrusions, forming a physical guide channel, restricting the lateral displacement of the workpiece to be printed, thereby avoiding problems such as blurred or incorrect steel stamp markings during the printing process, resulting in poor printing quality.
