High Speed ​​Roll Die Cutter Die Holder

Abstract

The invention discloses a high-speed roll-pressing die-cutting rule mould frame, which comprises a frame structure, two upper bearing pedestals, two lower bearing pedestals, an upper main cutter roll, a lower anvil roll and a pressurization mechanism, wherein the frame structure consists of two side plates, a top plate and a base; the two side plates are correspondingly provided with longitudinal chutes; the two upper bearing pedestals are fixedly arranged on the two side plates; the lower bearing pedestals are arranged on the side plates and can slide along the chutes under the driving of the pressurization mechanism; the upper main cutter roll is arranged between the two upper bearing pedestals; and the lower anvil roll is arranged between the two lower bearing pedestals. On the contrary with the traditional cutter mould frame, the high-speed roll-pressing die-cutting rule mould frame is characterized in that an interval between an upper roll and a lower roll is controlled by regulating the lower anvil roll assembly to achieve the use requirement, so that the vibration possibility of the upper main cutter roll in the high-speed production process is eliminated, and the purposes of improving the use effect and prolonging the service life are achieved. Meanwhile, pressure brought by the condition that a cutter point bears the self weight of the main cutter roll can be automatically eliminated, the user situation of the cutter point can be further improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of rolling die-cutting machinery, in particular to a high-speed rolling die-cutting knife mold base. Background technique [0002] At this stage, roll die-cutting technology is being used more and more widely at home and abroad. The industry involves non-woven fabrics, household paper, various packaging, printing, self-adhesive trademark labels, medical dressings, plastic products, leather products, daily necessities, electronics, etc. Products, batteries, metal foils, PE and PP films and other industries. [0003] With the development of various industries, the demand for improving the efficiency of die-cutting and reducing the cost of die-cutting is getting higher and higher, and the speed of die-cutting is getting faster and faster. Therefore, the high-speed roller die cutter mold base is required to have the following properties: 1. Higher precision and repeated installation accuracy; 2. Better rigidity; 3. Simpl...

AI Technical Summary

Problems solved by technology

The disadvantages of this knife holder are: the assembly process is complicated; the adjustment of the gap between the upper and lower knife rollers is troublesome and time-consuming; the wedges are easy to loosen when the die-cutting machine is running at high speed; Roller, prone to vibration during high-speed production

[0005] Moreover, compared with the performance that the above-mentioned high-speed roller die-cutting tool holder should have, the shortcomings of the traditional rotary die-cutting tool holder are becoming more and more obvious, mainly reflected in: the structural assembly process is complicated; the adjustment of the gap between the upper and lower knife rollers is troublesome and time-consuming; When running at high speed, the upper main knife roller will vibrate and affect the cutting; the re-grinding roller must be removed and reinstalled bearing seat, not only the accuracy cannot be guaranteed, but also the adjustment and loading and unloading efficiency of the knife roller is low
