Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a fixing device for paper cup and paper bowl printing plates. Background Technology

[0002] In the printing production of curved packaging products such as paper cups and bowls, the fixing and alignment accuracy of the printing plate is a key factor determining product quality. Currently, the printing plate fixing devices widely used in the industry have many technical limitations in terms of clamping methods and alignment adjustments, making it difficult to meet the demands of high-speed, high-precision modern production. Firstly, in terms of clamping structure, traditional devices mostly use manual screw clamping or pneumatic clamping. Manual screw clamping requires manually rotating bolts to drive the clamping plate to move, which is not only cumbersome and slow to respond, but the clamping adjustment time of a single device usually exceeds three seconds, seriously affecting the plate changeover of the production line. While pneumatic clamping improves response speed, its clamping force is unstable due to fluctuations in air pressure, making it prone to damaging the substrate due to excessive instantaneous pressure. Secondly, in terms of alignment adjustment, existing technologies mainly rely on manual visual observation of the alignment between the printing plate edge and the baseline, with manual adjustment of the position via knobs. This method is greatly affected by subjective factors such as operator experience and eyesight, making it difficult to meet the requirements of fine pattern registration. Frequent manual alignment can lead to production interruptions and capacity losses. Furthermore, the clamping and alignment mechanisms of traditional fixed devices are independent of each other, lacking a coordinated control mechanism. Utility Model Content

[0011] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: This utility model adopts a structured design. The device integrates a visual alignment auxiliary structure through an electromagnetically driven arc-shaped clamping structure, which greatly improves the device's compatibility with different printing processes and substrates. The device relies on the principle of electromagnetic induction to achieve rapid clamping of the printing plate. Compared with traditional manual screw clamping or pneumatic clamping methods, it can significantly shorten the downtime for printing plate changes and improve the continuous operation capability of the production line. When the arc-shaped clamp moves synchronously towards the center with the iron core block, it can form a uniform radial clamping force. This balanced force effectively avoids deformation problems such as wrinkles and warping of the printing plate caused by excessive local stress, ensuring the printing image... The printing plate remains intact and clear on the curved substrate of paper cups and bowls. Meanwhile, by adjusting the input current intensity of the electromagnetic coil, stepless clamping force control can be achieved within a certain range. The vision alignment assistance system, equipped with a high-definition industrial camera and advanced image recognition algorithm, can quickly and accurately identify the edge contour of the printing plate and the preset positioning marks. The time from image acquisition to completion of positioning deviation detection is less than or equal to one second, which greatly shortens the time spent on alignment adjustment. The position deviation data detected by the system can be directly linked to the fine adjustment mechanism of the fixture. Compared with the traditional manual eye alignment method, the alignment accuracy is greatly improved, the printing registration accuracy is kept stable, and the problem of deviation accumulation that is easy to occur in manual alignment is effectively solved.
