Abstract

The invention discloses a uniform-cutting cutting device for inflaming retarding environment-friendly polylactic acid plastic production, and relates to the technical field of polylactic acid plasticproduction. The device comprises a base and a fixed base, side stand columns are fixed to the left side and the right side of the base, a top plate is connected between the side stand columns, the side stand columns and the top plate are fixedly connected, a hydraulic rod is arranged below the top plate, a cutting plate is connected to the lower portion of the hydraulic rod, cutting plate slidingsleeves are arranged on the left side and the right side of the cutting plate, positioning columns are arranged in the middles of the cutting plate sliding sleeves, and the cutting plate sliding sleeves and the positioning columns are in embedded sliding connection. According to the uniform-cutting cutting device for inflaming retarding environment-friendly polylactic acid plastic production, thehydraulic rods and the cutting plates form a vertical sliding structure, the polylactic acid plastic is cut, the cutting plates can carry out up and down parallel movement in the vertical direction through telescopic operation of the hydraulic rods, and the polylactic acid plastic is cut.

Description

technical field [0001] The invention relates to the technical field of polylactic acid plastic production, in particular to a cutting device that can be uniformly cut for the production of flame-retardant and environment-friendly polylactic acid plastic. Background technique [0002] Polylactic acid is a polymer obtained by polymerizing lactic acid as the main raw material. The raw material source is sufficient and regenerable. The production process of polylactic acid is pollution-free, and the product can be biodegraded to realize the cycle in nature. Therefore, it is an ideal green polymer material. , PLA has good solvent resistance and can be processed in a variety of ways, such as extrusion, spinning, biaxial stretching and injection blow molding. In addition to being biodegradable, products made of polylactic acid are biocompatible. , gloss, transparency, hand feeling and heat resistance are good, so it is widely used and can be used as packaging materials, fibers and ...

AI Technical Summary

Problems solved by technology

[0003] When polylactic acid plastics are produced, they can be processed into various shapes for use. In order to facilitate processing, polylactic acid plastics are usually processed into flat sheets after being melted. According to different needs, the flat sheets need to be cut into different sizes, and the cutting work Generally, it is necessary to measure the size first, then establish the cutting line, and then cut it with an ordinary cutting device. The steps are relatively cumbersome, and a large amount of polylactic acid plastic needs to be cut, which makes the work efficiency low, and the cutting edge is uneven, and the dimensional accuracy is not high enough. Doesn't work with even cropping

[0004] The plastic cutting machine disclosed in the public specification CN207127983U of the Chinese utility model patent application, although the plastic cutting machine is provided with a parallel sliding cutting mechanism and a quickly replaceable cutting knife, it is easy to use and can quickly disassemble the cutting knife for replacement. The cutting blades of some plastic cutting machines are not easy to disassemble and replace. However, the cutting method set by this plastic cutting machine can only cut thin plastic sheets, which has low applicability and cannot perform continuous and uniform cutting work.
