[0026] See also Figure 1-4 As shown, a single-station loading and double-heating furnace EVA production line of the utility model comprises a frame, on which a loading mechanism and a heating mechanism are respectively arranged;

[0027] The feeding mechanism comprises an EVA material tray 1, a feeding mechanism horizontal moving motor 2, a feeding mechanism lifting motor 3 and a feeding mechanism lifting cylinder 4. The EVA material tray 1 is located below the frame, and the EVA material tray 1 can be placed with the EVA sheet to be processed. The feeding mechanism horizontal moving motor 2 is installed at one end of the top of the frame, and the feeding mechanism lifting motor 3 and the feeding mechanism lifting cylinder 4 are installed at the other end of the top of the frame. A vacuum suction cup assembly 5 is installed at the bottom end of the output shaft of the feeding mechanism lifting cylinder 4.

[0028] The heating mechanism includes a first infrared heating furnace 6 and a second infrared heating furnace 7. Infrared lamp heating plates are installed in the first infrared heating furnace 6 and the second infrared heating furnace 7. An EVA material conveying trolley 8 is arranged on one side of the first infrared heating furnace 6. A throwing swing head 9 is arranged on one side of the second infrared heating furnace 7. The throwing swing head 9 is externally connected to a PLC control system to realize automatic throwing.

[0029] Among them, a translation plate is arranged at the bottom of the feeding mechanism lifting motor 3 and the feeding mechanism lifting cylinder 4, and a translation guide rail 10 is installed on the translation plate, and the other end of the translation guide rail 10 is installed on the output shaft of the feeding mechanism translation motor 2. The feeding mechanism translation motor 2 can drive the translation plate together with the feeding mechanism lifting motor 3 and the feeding mechanism lifting cylinder 4 to translate left and right along the translation guide rail 10, so as to move the grabbed EVA sheet to the position where the EVA material conveying trolley 8 is located.

[0030] Among them, the vacuum suction cup assembly 5 includes a plurality of suction cups, which are distributed in a linear array. By driving the lifting cylinder 4 of the feeding mechanism, the suction cups on the vacuum suction cup assembly 5 can be driven to move up and down together. When the suction cup contacts the EVA sheet on the EVA material tray 1, the suction cup can be used to adsorb and fix the EVA sheet to complete the material grabbing. EVA sheets of different sizes can be grabbed and fixed by multiple suction cups, thereby greatly improving the applicability.

[0031] Among them, a Teflon mesh belt is arranged on the frame, and the Teflon mesh belt passes through the first infrared heating furnace 6 and the second infrared heating furnace 7 respectively, and the two ends of the Teflon mesh belt are respectively located below the EVA material conveying trolley 8 and the throwing swing head 9, and the Teflon mesh belt has translation and rotation functions, and the translation function is realized by driving the synchronous belt with a rotating motor. When the grabbed EVA sheet moves to the position where the EVA material conveying trolley 8 is located, the EVA material conveying trolley 8 together with the EVA sheet can be sent into the first infrared heating furnace 6 through the Teflon mesh belt, and continue to be sent into the second infrared heating furnace 7. At the same time, the next EVA sheet is sent into the first infrared heating furnace 6, so that two EVA sheets can be heated at the same time at one loading station. The first infrared heating furnace 6 and the second infrared heating furnace 7 are connected in series to realize different heating zones, so as to continuously and cyclically heat the same piece of EVA material, thereby effectively improving the production rhythm.

[0032] The circuits, electronic components and chip modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.

[0033] The standard parts used in the application documents can all be purchased from the market.

[0034] The working principle of the utility model is:

[0035] When the utility model is in use, firstly, all the electrical components in the production line are controlled by external switches and power supplies, and then the feeding mechanism lifting cylinder 4 is driven to drive the various suction cups on the vacuum suction cup assembly 5 to move downward together, until the suction cup contacts the EVA sheet on the EVA material tray 1, so that the EVA sheet can be adsorbed and fixed by the suction cup, and then the feeding mechanism lifting cylinder 4 is driven to lift the vacuum suction cup assembly 5 together with the EVA sheet upward to complete the material grabbing. At the same time, the feeding mechanism translation motor 2 is driven to drive the translation plate together with the feeding mechanism lifting motor 3 and the feeding mechanism lifting cylinder 4 to translate left and right along the translation guide rail 10, so as to move the grabbed EVA sheet to the EVA material conveying trolley 8. In the position, the EVA material conveying trolley 8 is then sent into the first infrared heating furnace 6 together with the EVA sheet through the Teflon mesh belt, and continued to be sent into the second infrared heating furnace 7. At the same time, the next EVA sheet is sent into the first infrared heating furnace 6, so that two EVA sheets can be heated at the same time in one loading station, and the heated EVA sheet can be exported to the top of the press mold through the throwing swing head 9 to realize automatic throwing. After that, the Teflon mesh drives the EVA material conveying trolley 8 to return, and the feeding mechanism places the new EVA sheet on the Teflon mesh belt, the mesh belt continues to rotate, and the new EVA sheet enters the first infrared heating furnace 6. Repeating the above actions can realize the functions of reciprocating feeding of the feeding mechanism and continuous heating of the heating mechanism.
