Technical Field

The invention relates to the field of die cutting tools, in particular to a high-performance rotary die cutting tool.

Background

The rotary die cutting machine is widely applied to processing of various flexible materials, two rollers rotate oppositely in production, and required products are processed under the pressing and cutting action of a cutting edge through extrusion and continuous feeding. Under long-time, large batch processing condition, hardness and the wearability of mould roller and round roller if do not reach the requirement, then can cause roll body surface wearing and tearing or scotch, lead to two roller clearance increases for local whole adhesion even takes place for the product, and the cutter cuts into the round roller roll body even and causes whole scrapping. The round roller and the die roller are made of integral imported steel or high-speed steel, and are used after turning, milling, heat treatment, grinding and other processes, so that the cost is high, the process is complex, and the processing cost is high. Because the cross cutting grinding roller laminates with the round roller machined surface each other for the round roller machined surface appears the wearing and tearing vestige with the corresponding shape of cross cutting grinding roller in same position, and just 1~2 months must carry out the coping to the round roller, influences machining efficiency, discards fast even.

Disclosure of Invention

The invention aims to provide a high-performance rotary die cutting tool which can effectively reduce the wear rate and prolong the service life.

The technical scheme adopted by the invention for solving the technical problem is to provide a high-performance rotary die cutting tool, which comprises: the die roller assembly and the round roller assembly are connected with a differential mechanism so as to enable the rotating speeds of the die roller assembly and the round roller assembly to be different.

Further, the mould roller subassembly is including installing on the knife rest and the mould roller roll body of being connected with differential mechanism, setting the cross cutting grinding roller on the mould roller roll body, and the circle roller subassembly is including installing on the knife rest and the circle roller roll body of being connected with differential mechanism, setting the circle roller machined surface on the circle roller roll body.

Furthermore, the processing surfaces of the die cutting grinding roller and the round roller are mutually attached.

Furthermore, a plurality of round roller processing surfaces are detachably mounted on the round roller body, so that the round roller is convenient to mount and dismount.

Further, an infrared flaw detection sensor is arranged on the die-cutting grinding roller.

Furthermore, the radius of the processing surface of the die cutting grinding roller is the same as that of the processing surface of the round roller.

Further, the differential consists of two sets of gears with different gear ratios.

Further, the difference of the number of teeth of the two groups of gears is less than 10.

Furthermore, the differential is also connected with a motor.

The invention has the beneficial effects that: 1. realize the rotation of mould roller and the little differential of circle roller through the design, guarantee that grinding roller and circle roller rotational speed are different under the same circumstances of radius, and both contact position change in real time, make the round roller atress even, reduce the wear rate, increase of service life. 2. The round roller is designed into a plurality of parts which are easy to disassemble and assemble, so that on one hand, the consumption of high-price materials is reduced, and the material cost is reduced. 3. When the round roller needs to be polished, the whole tool rest does not need to be detached, or the processing surface of the round roller is replaced, so that the production efficiency is improved. 4. The infrared sensor and the receiver are additionally arranged on the surface of the die roller, and the cutting edge of the die roller tool is subjected to real-time flaw detection, so that the defective rate is reduced, and the production benefit is improved.
