Problems solved by technology
[0004] At present, EVA pads are mainly obtained by manually measuring the size and then cutting, and the cutting work efficiency is low
Although the EVA automatic cutting device is disclosed in the patent literature, the automatic cutting of EVA can be realized, such as the EVA cutting device disclosed in the Chinese patent application whose publication number is CN102909747A and the title of invention is "EVA cutting device for solar panels". The cutting device is provided with a feeding roller, a combination of conveying rollers and a cutting combination, wherein a flat pressing device is provided between the feeding roller combination and the cutting combination, and the cutting combination includes a cutting cavity, and the entrance and exit of the cutting cavity There are roller shafts, a cutting knife is movable between the two roller shafts, a guiding inclined plate is arranged under the outlet of the cutting cavity, and a reciprocating moving material receiving rod is arranged under the guiding inclined plate, but the existing The advanced EVA cutting device can only get one EVA pad at one time, and the cutting efficiency is still low

The invention discloses an EVA cushion strip cutting tool. The cushion strip cutting tool comprises a cutting knife and a cutting knife fixing structure, the cutting knife fixing structure comprises afirst cutter support and a second cutter support used for being connected with the feeding end of a EVA sheet conveying device, gaps for EVA sheets to pass through is formed between the first cuttersupport and the second cutter support, the arrangement direction of the plurality of cutting knives is perpendicular to the conveying direction of the EVA sheets of the EVA sheet conveying device, anda part of cutting edges of the cutting knives penetrates through the gaps and are used for dividing the EVA sheets into strips. According to the cutting tool, the EVA sheets can be cut into multiplecushion strips at one time, and the cutting efficiency of an existing EVA sheets is improved.
Description
technical field [0001] The invention relates to an EVA pad strip cutting molding tool, in particular to an EVA pad strip cutting tool. Background technique [0002] In the field of chemistry and organic chemical industry, EVA refers to "ethylene-vinyl acetate copolymer" and the rubber and plastic foam material made of it. EVA is its English abbreviation, and its full English name is ethylene-vinyl acetate copolymer. [0003] EVA is solid at room temperature, and becomes a flowable liquid with a certain viscosity after being heated and melted to a certain temperature. It can be used to make refrigerator conduits, gas pipes, civil engineering plates, containers, etc. Equipment, hot melt adhesives, insulating layers, etc. In the solar cell industry, EVA pads are usually added at the overlapping positions of two adjacent busbars in the solar cell module to avoid short circuits and ensure smooth current export. Commonly used EVA pads are mainly rectangular pads of 130*50mm, 25*...
