Problems solved by technology

[0005] 1. It is necessary to manually transfer the materials multiple times, which is not only labor-intensive, but also inefficient;
[0006]Second, when cutting the mixed blanks, manual cutting is required, not only the accuracy cannot be guaranteed, but the blanks cut out cannot meet the requirements of subsequent Foaming requirements, but also a great consumption of physical strength of personnel;
[0007] 3. Manual feeding is required, and the dust generated during the feeding process poses a great safety hazard to the health of the staff

Embodiment 1

[0054] like figure 1 Shown, a kind of EVA shoe material production foaming process provided by the invention specifically comprises the following steps:

[0055] S1. Ingredients, in parts by weight, 45-50 parts of recycled materials, 35-39 parts of PE, 13-15 parts of AC, 0.3-0.6 parts of DCP, 0.1-0.2 parts of oxidation Zinc, 0.04 ~ 0.07 parts ST, and put the above-mentioned raw materials into the feeding mechanism 700 in the foaming device for EVA shoe material production;

[0056] S2, internal mixing, put the raw materials (except AC) in step S1 into the internal mixing mechanism 200 of the EVA shoe material production foaming device for pressurized mixing, and add AC after the mixing temperature reaches 120°C-125°C, Mixing without pressure, the mixing time lasts for 4-8 minutes, and then pressurized mixing again, when the temperature reaches 128 ° C ~ 135 ° C, the mixture is discharged;

[0057] S3, extrude, put the mixed material prepared in the step S2 into the extrusion...

Abstract

The invention discloses a foaming process and device for EVA shoe material production. The device comprises a base, a fixing frame, an internal mixing mechanism, an extrusion mechanism, a conveying assembly, a slitting mechanism and a feeding mechanism. According to the EVA shoe material production foaming device, the internal mixing mechanism, the extruding mechanism and the conveying assembly are matched with the slitting mechanism to achieve integrated production, not only is the slitting precision improved, but also manpower consumption is effectively reduced, and the production efficiency is improved; the automatic feeding function is achieved through the arranged feeding mechanism, physical output during manual material adding is further reduced, manual participation is not needed during material adding, the phenomenon that workers inhale a large amount of dust is avoided, and further guarantee is provided for the health of the workers; and through an arranged thickness adjusting assembly, the thickness of extruded blanks is rapidly adjusted, the device adapts to different production processes, and meanwhile, the device is simple in structure and convenient to use and maintain.

Description

technical field [0001] The invention relates to the technical field of EVA shoe material foaming, in particular to a foaming process for EVA shoe material production, and also to a foaming device for EVA shoe material production. Background technique [0002] Insoles are widely used as one of the most commonly used daily necessities. Nowadays, as people's pace of life is accelerating and their work is getting busier, people are paying more and more attention to self-care. The foot is a very important part of the human body. It is densely covered with rich capillaries and important acupuncture points. The health care and physical therapy of the feet can eliminate the fatigue of the whole body. [0003] Ethylene-vinyl acetate copolymer (Ethylene-VinylAcetate, EVA) rubber and plastic products are new environmentally friendly plastic materials, which have good cushioning, shock resistance, heat insulation, moisture resistance, and chemical corrosion resistance. They are non-tox...
