Abstract

The utility model relates to an inner waste discharge cutter for cutting mesh cloth PET (polyetherimide) bottom paper of a mobile phone. The cutter comprises a square base, wherein the left and right sides of the square base are respectively provided with a mounting hole, the square base, in the middle of the mounting holes, is provided with a cutter hole, a cutter is coaxially and fixedly arranged in the cutter hole, the cutter is a hollow cylindrical cutter, and the tip part of the lower end of the cutter is provided with an inner folding port. The cutter has the advantages that the cutter is provided with a hollow waste discharge hole, the hollow waste discharge hole is communicated with the upper part of a die plate, the waste is directly discharged out of the hollow cutter, and finally the waste penetrates through the die plate and is discharged out of the upper surface of the die plate, so the step of adhering the adhesive cloth to discharge the waste is eliminated, the production efficiency is improved, the use of adhesive tapes is saved, and the production cost is reduced.

Description

A kind of interior waste discharge cutter that cuts mobile phone screen cloth PET base stock

Technical field

The utility model belongs to cutter field, especially a kind of interior waste discharge cutter that cuts mobile phone screen cloth PET base stock.

Background technology

Earpiece screen cloth production is at present all elder generation's gluing on base stock, the reserved square gluing hole, surface of glue, the surface of the glue of again screen cloth being pasted, then will reserve square opening excision with cutter, the residue that cuts away of square opening is sticked out (waste discharge) by hole adhesive plaster again, and the method for residue in hole of removing so extremely wastes time and energy, waste adhesive plaster, the adhesive plaster of producing a similar equal size of a receiver screen cloth product needed, causes very large waste of material.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of interior waste discharge cutter of cutting mobile phone screen cloth PET base stock of reasonable in design, easy to use, interior waste discharge is provided.

The technical scheme that the utility model technical solution problem adopts is:

A kind of interior waste discharge cutter that cuts mobile phone screen cloth PET base stock, comprise a plinth, arranged on left and right sides at plinth is shaped with installing hole, on the plinth in the middle of installing hole, be shaped with cutting knife hole, in cutting knife hole, be coaxially fixedly mounted with cutting knife, described cutting knife is hollow barrel-type cutting knife, in the blade tip position, lower end of cutting knife, closes up.

And the upper surface of described cutting knife flushes with the upper surface, cutting knife hole of plinth.

And the upper surface of described cutting knife is between the upper surface and lower surface in the cutting knife hole of plinth.

And the cross sectional shape of described cutting knife is round rectangle.Advantage of the present utility model and good effect are:

1, the cutter that the utility model provides has hollow exhaust hole, waste discharge hole can lead to template above, hollow cutter just can directly be got rid of by waste material from cutter, final waste material is through template, discharge from template upper surface, saved the step that adopts rubberized fabric adhere waste discharge, production efficiency improves, save adhesive tape, reduce production costs.

2, this cutter can save reserved square gluing hole on base stock, directly gluing, then form BODY WITH SQUARE APERTURE by cutting, and avoid the operating procedure of gluing preformed hole, lower the loaded down with trivial details degree of production routine, improve yield rate.
