Description

Cutter structure of die cutting machine

Technical Field

The utility model belongs to the technical field of die cutting, and relates to a cutter structure of a die cutting machine.

Background

The flat-press flat die-cutting machine is one type of die-cutting machine, and in the working process of the flat-press flat die-cutting machine, a square die-cutting plate is arranged below an upper platform, and the upper platform is a fixed platform and is positioned above a die-cutting tooth row movement track. The die cutting plate is internally provided with a die cutting rule which is formed by a rule strip. The die cutting backing plate is arranged on a lower platform, the lower platform is a moving platform, each time a film is die-cut, the lower platform reciprocates up and down to be pressed against the upper platform once, and a die cutting knife cuts off a finished product from waste materials.

As shown in fig. 1 and 2, a square die-cutting plate 2 is provided with a die-cutting rule surrounded by a cutter bar 1, and when the cutter bar 1 is a single-sided edging first cutter bar 1A, the front side of the blade is arranged towards the die-cutting finished product side, and the inclined plane of the blade is arranged towards the waste discharge side; when the knife bar 1 is the double-sided symmetrical knife bar 1B with the edge, the setting direction is not needed to be selected.

The cutter structure of the die cutting machine adopting the technology can be used, but the cutter structure has the following defects:

when the single-sided edging nail cutter bar 1A is adopted as the cutter bar 1, the incisions on the finished product side are neat, but the unidirectional inclined plane of the cutter blade is subjected to a transverse component force, so that the cutter blade is easy to roll, and the service life of the cutter is relatively short.

When the cutter bar 1 adopts the B cutter bar 1B with double-sided symmetrical sharpening, the transverse component forces applied to the inclined planes in the two directions of the cutter blade are equal in action magnitude and opposite in direction and offset each other, and the cutter blade is not easy to sharpen, but the cutter blade is not easy to sharpen, the cutter blade can squeeze materials during die cutting, the cut on the finished product side is not complete enough, and the die cutting precision is not high enough.

In actual production, according to the specific die-cutting precision requirement of an order, the service life of the cutter and the die-cutting precision are required to be balanced, so that the service life of the cutter is prolonged as much as possible on the premise of meeting the die-cutting precision requirement.

In the cutter structure in the prior art, the die cutting precision and the service life of the cutter can be only selected from two, the freedom degree of selection is insufficient, and the use effect is not ideal.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides the cutter structure of the die cutting machine, which can prolong the service life of the cutter as much as possible on the premise of meeting the requirement of die cutting precision, has higher freedom of selection and more ideal use effect.

The technical scheme adopted by the utility model for achieving the technical purpose is as follows: the cutter structure of the die cutting machine is characterized in that a square die cutting plate is provided with a die cutting rule surrounded by cutter bars, wherein the cutter bars are propyl cutter bars provided with asymmetric double-sided blades; the two edge surfaces of the double-sided edge of the third blade are a first edge surface and a second edge surface respectively, and the inclined included angle between the first edge surface and the corresponding surface of the blade body is smaller than the inclined included angle between the second edge surface and the corresponding surface of the blade body; the first blade surface is against the finished side of the die cutting.

The inclined included angle between the first blade surface and the corresponding surface of the cutter bar body is 10-15 degrees; the inclined included angle between the edge face B and the corresponding face of the cutter bar body is 30-40 degrees.

The beneficial effects of the utility model are as follows: because the two edge surfaces of the asymmetric double-sided edge of the third blade 1C are the first edge surface X and the second edge surface Y respectively, the inclined included angle between the first edge surface X and the corresponding surface of the blade 1 body is smaller than the inclined included angle between the second edge surface Y and the corresponding surface of the blade 1 body; the edge surface X is close to the side of the die-cut finished product, and has the following advantages:

the cut on the finished product side is not as regular as the single-sided edging first knife bar 1A, but is relatively more regular than the double-sided symmetrical edging second knife bar 1B; the service life of the cutter is not longer than that of the double-sided symmetrical edging ethyl cutter bar 1B, but is longer than that of the single-sided edging methyl cutter bar 1A, because the inclined planes in two directions of the cutter are not equal in the action of the transverse component forces, but opposite in the direction, parts of the transverse component forces are counteracted, the transverse stress of the cutter bar is smaller than that of the single-sided edging methyl cutter bar 1A, and the cutter is relatively difficult to sharpen; according to the specific die cutting precision requirement of the order, the flexibility is higher when the service life of the cutter and the die cutting precision are required to be balanced, and the use effect is more ideal.

In the embodiment of the utility model, as shown in fig. 3 and referring to fig. 1, in a cutter structure of a die-cutting machine, a square die-cutting plate 2 is provided with a die-cutting rule surrounded by a cutter bar 1, and the cutter bar 1 is a propyl cutter bar 1C provided with asymmetric double-sided blades; the two edge surfaces of the double-sided edge of the third blade 1C are a first edge surface X and a second edge surface Y respectively, and the inclined included angle between the first edge surface X and the corresponding surface of the blade 1 body is smaller than the inclined included angle between the second edge surface Y and the corresponding surface of the blade 1 body; the first blade face X is against the finished side of the die cut.

The inclined included angle between the first cutting edge surface X and the corresponding surface of the cutter bar 1 body is 10-15 degrees; the inclined included angle between the edge face Y of the second blade and the corresponding face of the cutter bar 1 body is 30-40 degrees.

Further description of the utility model:

a, when the die cutting machine cuts the thickest material, the inclined included angle between the first blade surface X and the corresponding surface of the cutter bar 1 body is 10 degrees; the inclined included angle between the second blade surface Y and the corresponding surface of the cutter bar 1 body is 30 degrees.
