Abstract

The invention provides a kind of EVA foam processing technique, including step 1) EVA divides bar, corner cut, and lamellar EVA material is carried out a point bar, is cut into strip EVA；Then, use laser cutter mould that described strip EVA two is carried out corner cut；Step 2) double faced adhesive tape divides bar: use cutting machine that whole double faced adhesive tape material is cut into strip；Step 3) laminating: by described step 1) in strip EVA after point bar, corner cut and step 2) in double faced adhesive tape after point bar use compounding machine laminating, form web-like band glue EVA；Step 4) cross cutting: use laser cutter mould by die-cutting machine by described step 3) in web-like band glue EVA carry out cross cutting processing, formation EVA foam semi-finished product；Step 5) artificial useless, packaging: form EVA foam finished product.By the EVA foam processing technique type-setting mode of this case, effectively raising production efficiency, easily, counting is accurate in operation, saves material about 8%, and saves artificial, reduces workload and cost.

Description

A kind of EVA foam processing technique
Technical field
The present invention relates to EVA foam production technical field, particularly relate to a kind of EVA foam processing technique.
Background technology
Conventional belt glue EVA foam product is mainly used in the packaging of electronic product, a large amount of manual during production Supporting, process equipment is mainly based on punch press, and production efficiency low (10 beats/min), labor intensity is big.Generally EVA material is sheet Material (2 meters * 1.5 meters * 5 millimeters), one side is manual sticks double faced adhesive tape, carries out punch process with timber shuttering, logical in each material joint Often have 8 flake products and cause scrapping because of material joint.As Figure 2-3, EVA billot 1 is the most square, between the first billot 2 There is EVA joint 4 in two billots 3, causes waste of material more, and it is low, manually that the processing mode of conventional belt glue EVA exists production efficiency Load is big, and operation danger is high, the problem that waste of material is big.
Summary of the invention
The invention provides the EVA foam processing technique of a kind of simple in construction, it is intended to effectively improve production efficiency, saving Material.
A kind of EVA foam processing technique, including:
Step 1) EVA divides bar, corner cut, and lamellar EVA material is carried out a point bar, is cut into strip EVA；Then, laser scalpel is used Mould carries out corner cut to described strip EVA two；
Step 2) double faced adhesive tape divides bar: use cutting machine that whole double faced adhesive tape material is cut into strip；
Step 3) laminating: by described step 1) in strip EVA after point bar, corner cut and step 2) in double faced adhesive tape after point bar Employing compounding machine is fitted, and forms web-like band glue EVA；
Step 4) cross cutting: by die-cutting machine by described step 3) in web-like band glue EVA carry out cross cutting processing, form EVA Foam semi-finished product；
Step 5) artificial useless, packaging: form EVA foam finished product.
Further, described step 1) in lamellar EVA material a size of 2 meters * 1.5 meters * 5 millimeters.
Further, described step 1) in also include 5-10 is opened EVA material tiling superposition after be cut into strip together EVA。
Further, described step 1) in strip EVA a size of 0.3 meter * 2 meters * 5 millimeters.
Further, described step 2) in the double faced adhesive tape width cutting into strip be 0.3 meter.
Further, described step 5) in EVA finished product in turning shape.
Have employed technique scheme, the invention has the beneficial effects as follows: by the EVA foam processing technique typesetting side of this case Formula, effectively raises production efficiency, and easily, conveniently, counting is accurate in operation, saves material about 8%, and saves manually, fall Low workload and cost.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and It is not used in the restriction present invention.
A kind of EVA foam processing technique, as it is shown in figure 1, include:
Step 1) EVA divides bar, corner cut, and lamellar EVA material is carried out a point bar, is cut into strip EVA；Then, laser scalpel is used Mould carries out corner cut to described strip EVA two；
Step 2) double faced adhesive tape divides bar: use cutting machine that whole double faced adhesive tape material is cut into strip；
Step 3) laminating: by described step 1) in strip EVA after point bar, corner cut and step 2) in double faced adhesive tape after point bar Employing compounding machine is fitted, and forms web-like band glue EVA；
Step 4) cross cutting: by die-cutting machine by described step 3) in web-like band glue EVA carry out cross cutting processing, form EVA Foam semi-finished product；
Step 5) artificial useless, packaging: form EVA foam finished product.
Described step 1) in lamellar EVA material a size of 2 meters * 1.5 meters * 5 millimeters.
Described step 1) in also include 5-10 is opened EVA material tiling superposition after be cut into strip EVA together.
Described step 1) in strip EVA a size of 0.3 meter * 2 meters * 5 millimeters.
Described step 2) in the double faced adhesive tape width cutting into strip be 0.3 meter.
Described step 5) in EVA finished product in turning shape.
EVA is combined with double faced adhesive tape by this case by compounding machine, and between bar and bar, gap should be the least and two-sided Glue can not exceed EVA edge.New processing technique uses the processing thought of cross cutting, uses compounding machine by double faced adhesive tape and to cut into bar The EVA (0.3 meter * 2 meters * 5 millimeters) of shape corner cut is combined, and forms the coiled strip of long 50 meters, carries out Fast Modular on die-cutting machine Cut (100 beats/min), as illustrated in figures 4-5, show respectively the EVA joint 6 of the billot 5 after EVA corner cut and this case, it is clear that Visible can't cause waste；And scrap because of joint at material joint generally only 1-2 sheet.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
