A kind of polyester plastic film sheet preparation intelligent die-cutting machine

Abstract

The invention belongs to the technical field of new material manufacturing, and specifically relates to an intelligent die-cutting machine for preparing polyester plastic film sheets, which includes a base plate on which a first reversing roller, a winding roller, and a second reversing roller parallel to each other are installed. , conveying roller, the first driving roller and the second driving roller, and the first sealing cylinder, the second sealing cylinder and the portal frame; the outer surface of the first driving roller and the second driving roller is installed with a conveyor belt; there are two conveyor belts a circular through groove, and a through hole is evenly opened around the circular through groove; a hollow sealing ring is installed on the outer surface of the first sealing cylinder; Two piston barrels; a cutting mechanism is installed on the top plate of the portal frame. When the invention is used for circular cutting of polyester plastic film, the processing efficiency is improved, and the injury of the operator's hand by the cutting blade is avoided. Wrinkles will not be formed on the polyester film belt during the cutting process, and the edge of the circular sheet is Smooth and jagged.

Description

technical field [0001] The invention belongs to the technical field of new material manufacturing, and in particular relates to an intelligent die-cutting machine for preparing polyester plastic film sheets. Background technique [0002] Polyester plastic film is a film material made of polyethylene terephthalate as a raw material, which is made into a thick sheet by extrusion and then biaxially stretched. It is widely used in building materials, printing, medical and health industries. Polyester plastic film usually needs to be cut into different shapes with a die-cutting machine, and the more common ones are round, rectangular, triangular, etc. In the actual production process, the existing die-cutting machine has the following problems when the polyester plastic film is cut circularly: (1) after the polyester film tape is cut, the edge of the cut circular sheet will be damaged by static electricity. The effect of adsorption on the polyester film belt makes the circular s...

Problems solved by technology

[0004] The invention provides an intelligent die-cutting machine for preparing polyester plastic film sheets, the purpose of which is to solve the following problems when carrying out circular cutting of polyester plastic films: (1) after the cutting of polyester film bands is completed, The edge of the cut circular sheet will be adsorbed on the polyester film belt due to static electricity, so that the circular sheet cannot fall freely, and the operator needs to remove it by hand. This process reduces the processing efficiency, and Cutting blade is easy to cause injury to operator's hand during operation; The friction between the polyester film bands causes wrinkles to be formed on the polyester film bands, and the cut circular sheet is irregular in shape; (3) the cutting blade directly cuts the polyester film bands in a single direction and easily causes the circles cut into jagged edges on shaped sheets reduce cut quality
