Technical Field

[0001] The utility model relates to the field of injection molding machines, in particular to an environmentally friendly injection molding machine for EVA soles. Background Art

[0002] EVA soles, whose full name is ethylene-vinyl acetate copolymer soles, are a polymer material widely used in the shoemaking industry. EVA material has the advantages of being light, soft, elastic, resistant to aging, ozone, low temperature, and shock-resistant. It is also easy to process and dye, so it is often used to make midsoles or outsoles of various sports shoes, casual shoes, slippers, and children's shoes. EVA soles are usually produced through injection molding. EVA soles produced by injection molding machines have the advantages of high production efficiency, high material utilization, and environmental protection and energy saving. Therefore, injection molding machines are usually used in the production of EVA soles.

[0003] In the process of producing EVA soles, the mechanical movement of the injection molding machine will inevitably produce some noise, which can easily cause environmental pollution. In addition, when the injection molding machine is producing soles, some volatile organic compounds, smoke and other harmful gases may be generated during the hot melting of raw materials and injection molding process. These harmful gases are directly discharged under control and are not only easy to pollute the environment, but also easy to cause harm to human health, reducing the practicality of the injection molding machine. Summary of the invention

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides an environmentally friendly injection molding machine for EVA soles to solve the above-mentioned technical problems.

DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] like Figure 1 As shown, the utility model provides an environmentally friendly injection molding machine for EVA soles, comprising a support base 1 and an injection molding machine body 2 fixedly mounted on the support base 1;

[0023] When in use, raw materials are prepared and the injection molding machine body 1 is controlled to perform heating, melting, injection molding and other processing steps to produce EVA soles.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, a protective cover 3 covering the outside of the injection molding machine body 2 is locked and fixed on the top of the support seat 1, and a sound-absorbing cotton 4 is pasted on the inner wall of the protective cover 3. The sound-absorbing cotton 4 absorbs the noise generated during the operation of the injection molding machine body 2 to reduce the noise pollution caused by the injection molding machine body 2, and a cooling fan 5 is fixed on the top of the inner side of the protective cover 3 to assist in cooling the EVA sole after molding. A slide groove 10 is vertically opened at the front end of the protective cover 3;

[0025] An air suction hood 6 embedded in the top of the support base 1 is provided below the cooling fan 5. The air suction hood 6 is connected to the air suction end of the air suction fan 9 through a connecting pipe 8. The air suction fan 9 is locked and fixed inside the support base 1, and a purification component for purifying harmful gases in the injection molding machine body 2 is provided at the air outlet end of the air suction fan 9;

[0026] A baffle 11 is slidably installed in the chute 10, and a working window 12 which is connected to the inner side of the protective cover 3 is opened at the right end of the inner side of the chute 10, and the EVA sole produced by the injection molding machine body 2 can be taken out through the working window 12;

[0027] The length of the baffle 11 is less than the inner length of the chute 10, and when the baffle 11 slides to the inner right end of the chute 10, the inner side of the working window 12 is completely covered, so that the baffle 11 covers the working window 12, thereby reducing the harmful gas generated by the injection molding machine body 2 from polluting the environment;

[0028] In this embodiment, a filter screen 7 flush with the top surface of the support seat 1 is installed on the inner top of the air suction cover 6, so as to facilitate preliminary filtering of the inhaled gas through the filter screen 7, and also prevent the formed EVA sole from falling into the air suction cover 6;

[0029] In this embodiment, the suction hood 6 is tapered from top to bottom, and the bottom of the inner side of the suction hood 6 corresponds to the size of the top of the connecting pipe 8, so that the suction hood 6 can absorb harmful gases generated during the operation of the injection molding machine body 2 through the connecting pipe 8;

[0030] In this embodiment, a plurality of air holes are provided on the top of the protective cover 3, and the distribution area of ​​the air holes corresponds to the air inlet end of the air cooler 5, so as to facilitate cooling the inner side of the protective cover 3 and facilitate the air cooler 5 to introduce external air to cool the EVA sole;

[0031] The inner top of the working window 12 is higher than the top surface of the injection molding machine body 2, so that the EVA sole in the injection molding machine body 2 can be easily taken out through the working window 12;

[0032] When in use, the sound-absorbing cotton 4 and the protective cover 3 absorb part of the noise generated by the injection molding machine body 2 when it is working, thereby reducing the noise pollution of the injection molding machine body 2;

[0033] After the injection molding machine body 2 produces the EVA sole, the injection molding machine body 2 is turned on. At this time, the air cooler 5 and the suction fan 9 are controlled to start, and the EVA sole is blown by the air cooler 5 to assist in cooling the EVA sole. After the suction fan 9 is started, the connecting pipe 8 and the suction hood 6 are used to absorb harmful gases in the injection molding machine body 2 to reduce the pollution of the environment by harmful gases. After the air cooler 5 and the suction fan 9 have worked for a period of time, the baffle 11 is pulled to open the working window 12 to take out the EVA sole that has been injected.

[0034] like Figure 3 As shown, the purification assembly in this embodiment includes a connecting pipe 13 plugged into the air outlet end of the suction fan 9, a fixed box 14 connected to the connecting pipe 13, a partition 15 horizontally installed inside the fixed box 14 and located obliquely below the connecting pipe 13, and an activated carbon filter 16 fixed on the top of the partition 15 for adsorbing harmful substances in the harmful gas;

[0035] The fixed box 14 is connected to the inner side of the support base 1. A through hole 17 is provided at the top of the partition 15 away from the end of the connecting pipe 13 for guiding the conveying gas. A water inlet pipe 18 is installed at the bottom of the partition 15 near the end of the connecting pipe 13. An atomizing nozzle 19 for spraying purified water is installed at the bottom of the water inlet pipe 18. An exhaust pipe 20 is provided on the side of the water inlet pipe 18 away from the through hole 17. Both ends of the exhaust pipe 20 pass through the inner side of the fixed box 14 and the inner wall of the support base 1 respectively.

[0036] The bottom end surface of the atomizing nozzle 19 is higher than the exhaust pipe 20, so that when the gas enters the exhaust pipe 20, the water sprayed by the atomizing nozzle 19 absorbs the harmful gas;

[0037] When in use, the end of the water inlet pipe 18 away from the fixed box 14 is connected to an external water inlet device, and the harmful gas sucked in by the suction fan 9 is introduced into the fixed box 14 through the connecting pipe 13, and some harmful substances in the gas are filtered out by the activated carbon filter 16. The filtered gas flows downward through the through hole 17, and purified water is transported to the atomizing nozzle 19 through the water inlet pipe 18, and is sprayed downward through the atomizing nozzle 19. The harmful gas is absorbed by the water droplets, and the purified gas is discharged to the outside through the exhaust pipe 20, thereby reducing the pollution of the environment by harmful gases and being more conducive to environmental protection.

[0038] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
