Sheet PLA composite press cutting machine

Abstract

The invention provides a sheet PLA composite press cutting machine comprising a box, a safety door, an uncoiling device, a conveying roller group, a reversing roller group, a forming device and an outputting roller group. Continuous uncoiling action of a sheet PLA composite is achieved through the uncoiling device. The sheet PLA composite is conveyed to the forming device through the conveying roller group. The forming device cuts the sheet PLA composite into strips which are apparently separated but actually connected, or the forming device presses strip-shaped indentations on the sheet PLA composite, or the forming device wrinkles the sheet PLA composite to be zigzag; and the sheet PLA composite is made to meet the demand of a cooling section of a cigarette free of combustion at low temperature. The formed sheet PLA composite is output through the outputting roller group, and conditions are provided for follow-up coiling procedure.

Description

Technical field: [0001] The invention belongs to the technical field of sheet material processing and molding equipment, and in particular relates to a sheet PLA composite material press-cutting machine. Background technique: [0002] Traditional tobacco is a high-temperature combustion type. With the development of the times, the harm of second-hand smoke from traditional tobacco has attracted more and more attention. With the advancement of technology, new types of tobacco, that is, low-temperature non-burning cigarettes have appeared in response to the market; this type of tobacco is flue-cured tobacco, does not produce second-hand smoke, does not burn, is fashionable and avant-garde, and is less harmful to the human body. Low-temperature non-burning cigarettes are provided with a heating device at the front end of the cigarette, and the heating device is used to heat the cigarette to generate smoke, and a cooling section is provided at the rear end of the cigarette. The...

Problems solved by technology

The cooling section of low-temperature non-burning cigarettes is also different from the filter tip of traditional cigarettes. It usually uses thin-sheet PLA materials. PLA materials are a new type of bio-based and renewable biodegradable materials, using renewable plant resources, such as cereal grains. It is made of starch raw materials such as husk, straw, wheat straw, etc. PLA materials are generally hard in texture, and it is difficult to directly roll them into the shape of cigarette filters, and it is difficult to roll them into shapes. Therefore, when making PLA materials into low-temperature non-combustible During the cooling section of cigarettes, the flat and relatively hard thin PLA material is usually shredded into strips of uniform specifications, and then rolled by a winding device, or Firstly, strip indentations are pressed on the thin-sheet PLA composite material, and then rolled up by the winding equipment. The strip-shaped indentations can facilitate winding and forming when the sheet is wound into a roll, or the thin-sheet PLA composite material is wrinkled and formed. , so that the sheet PLA composite material folds into a zigzag shape, which provides convenience for winding and forming. However, there is no corresponding shredding or creasing or folding forming equipment for special PLA materials on the market.
