Description

Technical Field

[0001] The utility model belongs to the technical field of plastic thermoforming machine cutting, and more specifically, particularly relates to a precise material cutting device for a plastic thermoforming machine. Background Art

[0002] A plastic thermoforming machine is a machine that sucks heated and plasticized thermoplastic plastic coils such as PVC, PE, PP, PET, and HIPS into various shapes of high-grade packaging and decoration boxes, frames and other products. This forming process mainly uses the vacuum suction generated by a vacuum pump to suck the heated and softened thermoplastic sheet through a mold into various shapes of vacuum covers, plastic trays, blisters, etc.

[0003] When producing plastic trays, basically a whole board of plastic trays is produced first. There are multiple independent plastic trays on a whole board of plastic trays. In subsequent processing, it is necessary to cut the whole board of plastic trays. Different plastic trays require different die-cutting components. Most of the existing cutting equipment for plastic trays places a whole board of plastic trays on the corresponding die-cutting components for cutting, and multiple independent plastic trays can be cut conveniently and quickly.

[0004] However, the production cost of the die-cutting components is relatively high. When the manufacturer trial-produces plastic tray samples or produces a small quantity for the demander of plastic trays, using the corresponding die-cutting components will result in a relatively high production cost.

[0005] In summary, therefore, the utility model provides a precise material cutting device for a plastic thermoforming machine to solve the above problems. Content of the Utility Model
