Intelligent die-cutting machine for preparing polyester plastic film sheets

Abstract

The invention belongs to the technical field of new material manufacturing, and particularly relates to an intelligent die-cutting machine for preparing polyester plastic film sheets. The intelligentdie-cutting machine comprises a base plate. A first reversing roller, a winding roller, a second reversing roller, a conveying roller, a first driving roller and a second driving roller which are parallel to one another are installed on the base plate. A first sealing barrel, a second sealing barrel and a portal frame are also installed on the base plate. A conveying belt is installed on the outersurface of the first driving roller and the outer surface of the second driving roller. Two circular through grooves are formed in the conveying belt, and through holes are evenly formed around the circular through grooves. A hollowed sealing ring is installed on the outer side face of the first sealing barrel, and a first piston barrel is installed on the outer side of the hollowed sealing ring.A second piston barrel is installed on the outer side of the top of the second sealing barrel. A cutting mechanism is installed on a top plate of the portal frame. When the intelligent die-cutting machine is used for circularly cutting polyester plastic films, processing efficiency is improved, harm to the hands of operators by cutting blades is avoided, no wrinkle can be formed on polyester filmstrips in the cutting process, and the edges of the circular sheets are smooth without sawteeth.

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
