Economical bottom-paper-free high-speed cutting die machining device

Abstract

The invention discloses an economical bottom-paper-free high-speed cutting die machining device. The economical bottom-paper-free high-speed cutting die machining device comprises a rack, a die cutting material uncoiling roll which is axially arranged on the rack, a protection bottom paper uncoiling roll which is axially arranged on the rack, a die cutting knife roll and a die cutting bottom roll which are separately axially arranged on the rack on one side of the die cutting material uncoiling roll and are vertically parallel to each other, a die cutting scrap coiling roll which is axially arranged on the rack and is located on one side of the outlet of a die cutting passage and a protection bottom paper coiling roll which is axially arranged on the rack and is located on one side of the die cutting passage and below the die cutting scrap coiling roll. According to the economical bottom-paper-free high-speed cutting die machining device, protection bottom paper is fed in during die cutting processing, and a knife blade edge on the die cutting knife roll is prevented from being in direct contact with a roll surface of the die cutting bottom roll, so that the roll surface of the die cutting bottom roll is protected, and the service life of a knife blade on the die cutting knife roll and the service life of the die cutting bottom roll are prolonged.

Description

technical field [0001] The invention relates to the technical field of label processing equipment, in particular to an economical high-speed die-cutting processing device for bottomless paper. Background technique [0002] At present, the roll-to-roll die-cutting equipment in the label industry can die-cut the printed graphics and texts on the roll material into the required single-shaped labels. The roll-to-roll die-cutting equipment can be roughly divided into two types. The categories are "half-cut" die-cutting equipment and "full-cut punching" die-cutting equipment. The cutting dies on the "full cutting and punching" die cutting equipment can be divided into three types: [0003] The first is a fully automatic solid circular die-cutting die-cutting engraving knife mold. The material of the knife mold is made of carbon steel as raw material, and it is precisely carved by CNC. The development cycle of the knife mold is very long, and it is difficult for the knife mold man...

AI Technical Summary

Problems solved by technology

[0003] The first is a fully automatic solid circular die-cutting die-cutting engraving knife mold. The material of the knife mold is made of carbon steel as raw material, and it is precisely carved by CNC. The development cycle of the knife mold is very long, and it is difficult for the knife mold manufacturing technology The requirements are extremely high, and the cost of cutting dies is expensive. This type of die-cutting process is especially suitable for orders with large production volumes, but not suitable for small orders.

[0004] The second type is a fully automatic solid flattening punching and engraving knife mold. The material of this knife mold can be made of ordinary S45C steel, which is also precisely carved by CNC, but its knife making technology is slightly better than the first kind of knife. The difficulty coefficient of the mold is lower. Through the cooperation of the upper and lower male and female dies, it is similar to the principle of scissors. The development cycle of this kind of die is longer than the opening period of the first die die, and the cost of die die is more expensive than that of the first die die. Expensive, this type of die-cutting process is especially suitable for orders with large production volumes and relatively thick materials

[0005] The third type is the semi-automatic flat die-cutting die-cutting engraving knife die, which is stamped by the equipment and manually taken after each die-cutting. The cost of the die-cutting die is relatively low, and it is only suitable for small samples, but it cannot be mass-produced.

[0006] From the perspective of cost, these three cutting dies have their own advantages and disadvantages. Judging from the fact that the current customers are testing the market with a small amount of variety, these three cutting dies cannot adapt to the competition in the market.

In addition, the existing "full cutting and punching" die cutting equipment also has the following problems: 1. The blade blade on the die die directly contacts the die-cutting bottom roller, and the material is partially cut off by pressure, which shortens the life of the blade on the die die. Usually only 100,000 times; 2. The material of the die roller is a one-time investment. If the blade is worn or the order is produced, the entire die roller can only be scrapped, which is expensive
