[0026] Please refer to Figures 1 to 5 The embodiment of the application provides an energy-saving EPP production line, which comprises a forming machine body 1 and a taking device 2, wherein the forming machine body 1 comprises a fixed mold 11, a movable mold 12 matched with the fixed mold 11 and a driving mechanism 13 for driving the movable mold 12 to open and close.

[0027] The forming machine body 1 further comprises a heating mechanism, a feeding mechanism and an electric control mechanism. The feeding mechanism fills raw materials into the fixed mold 11 and the movable mold 12, and the heating mechanism heats and controls the temperature of the raw materials in the mold cavity until the raw materials are formed. The forming body is prior art, and the embodiment of the application does not improve the forming body, so the forming body will not be described in detail.

[0028] The taking device 2 comprises a telescopic mechanism 21, a support frame 22 arranged at the output end of the telescopic mechanism 21, a rotating mechanism 23 arranged on the support frame 22 and a suction cup assembly 24 arranged on the rotating mechanism 23. The rotating mechanism 23 comprises a rotating arm 231 rotatably arranged on the support frame 22 and a driving assembly 232 for driving the rotating arm 231 to rotate. The suction cup assembly 24 is arranged at one end of the rotating arm 231 facing the fixed mold 11.

[0029] In the application, the support frame 22 is extended into the space between the fixed mold 11 and the movable mold 12 through the telescopic mechanism 21, then the rotating arm 231 is driven to rotate by the driving assembly 232 to a certain angle, so that the suction cup assembly 24 on the rotating arm 231 is opened and opposite to the formed product on the fixed mold 11, then the formed product is sucked by the suction cup assembly 24, and then the rotating arm 231 is driven to rotate in the opposite direction by the driving assembly 232 to a certain angle, so that the formed product is as much as possible to be folded, and the support frame 22 and the formed product are taken out from the space between the fixed mold 11 and the movable mold 12 through the telescopic mechanism 21. The formed product can be taken out from the narrow space between the movable mold 12 and the fixed mold 11 without manual operation, the safety is improved, and the production efficiency is improved.

[0030] Specifically, since the guide shaft is arranged between the movable mold 12 and the fixed mold 11 for the opening and closing movement of the movable mold 12, the space between the movable mold 12 and the fixed mold 11 is small, and multiple cavities are often arranged between the movable mold 12 and the fixed mold 11, so that the extrusion molding of multiple products can be completed at one time. After the external equipment extends into the movable mold 12 and the fixed mold 11, it cannot effectively adsorb the molded product. The rotating arm 231 enters the movable mold 12 and the fixed mold 11 in the storage state, then the rotating arm 231 is opened to adsorb the molded product, and then the molded product is taken out from the movable mold 12 and the fixed mold 11 by the storage of the rotating arm 231, so that the work in a narrow space can be realized, and the taking of the molded product can be completed.

[0031] In some embodiments, the rotating arm 231 comprises two driving plates 2311 and an adjusting plate 2313, wherein:

[0032] Both of the two driving plates 2311 are rotatably connected to the support frame 22 through the rotating shaft 2312.

[0034] In the present application, the adjusting plate 2313 is used to install the suction cup assembly 24, and the rotation of the two driving plates 2311 drives the rotation of the adjusting plate 2313, which can ensure that the driving plates 2311 will not be skewed during rotation, thereby improving the stability of the molded product adsorption, so that the angle of the molded product will not change, and then the rotating arm 231 can conveniently drive the molded product to be stored and extracted from the movable mold 12 and the fixed mold 11.

[0035] In some embodiments, the rotating arm 231 further comprises a gear 2314 arranged on the outer circumferential side of the rotating shaft 2312; and the driving assembly 232 comprises a driving cylinder 2321, a mounting plate 2322 and a rack 2323, wherein:

[0040] In some embodiments, the rotating mechanism 23 includes two rotating arms 231 opposite to each other, the installation plate 2322 is located between the two rotating arms 231, and the installation plate 2322 is provided with a rack 2323 on both sides.

[0041] In the present application, the rotating arms 231 on both sides are driven to rotate by the racks 2323 on both sides of the installation plate 2322. Specifically, the height of the installation plate 2322 is located at the middle position of the movable mold 12 and the fixed mold 11. By rotating the upper and lower rotating arms 231 to open, the upper and lower molded products can be sucked at the same time.

[0042] In some embodiments, the taking device 2 is provided with a plurality of rotating mechanisms 23, the plurality of rotating mechanisms 23 are arranged along the moving direction of the installation plate 2322, and the plurality of rotating mechanisms 23 share one driving assembly 232.

[0043] Specifically, the number of rotating mechanisms 23 of the taking device 2 is two, which is suitable for taking four molded products at the same time. Each rotating mechanism 23 can suck two molded products opposite to each other, and a total of four molded products can be taken at the same time. The rotating mechanism 23 can also be set to three, four or five according to actual conditions.

[0045] In the present application, the installation 2 is driven to move by the telescopic cylinder 241, so that the vacuum suction cup 243 on the mounting bracket 242 can fully adsorb the molded product, and then the mounting bracket 242 is reset to drive the molded product to leave the mold cavity of the fixed mold 11.

[0046] In some embodiments, the telescopic mechanism 21 includes a fixed bracket 211, a guide column 212 and a linear cylinder 213, wherein:

[0047] The fixed bracket 211 is arranged on one side of the molding machine body 1, and the fixed bracket 211 is provided with a guide hole.

[0048] The guide column 212 is slidingly arranged in the guide hole, and the end of the guide column 212 is connected with the support bracket 22.

[0049] The linear cylinder 213 is arranged on the fixed frame 211, and the output end of the linear cylinder 213 is connected with the support frame 22.
