Technical Field

[0001] The utility model relates to the field of bio-based thermoplastic vulcanizate, in particular to a bio-based thermoplastic vulcanizate internal mixing and plasticizing device. Background Art

[0002] The mixing process of bio-based thermoplastic vulcanizate is to mix bio-based polymers (such as polylactic acid PLA, bio-based polyester, natural rubber, etc.) with other additives (such as plasticizers, cross-linking agents, fillers, etc.) at high temperature and partially vulcanize them to form a new material that has both rubber elasticity and plastic thermoplastic processing characteristics.

[0003] The existing internal mixing of bio-based thermoplastic vulcanizates is to pour the raw materials into an internal mixer after quantitative mixing, and then shear, extrude, mix and plasticize them. However, since the quantitative mixing of raw materials needs to be done manually, it consumes manpower and is slow. In addition, when the raw materials are quantitatively mixed manually, mixing errors may occur, which affects the performance of the bio-based thermoplastic vulcanizate and is relatively inconvenient.

[0004] Therefore, a bio-based thermoplastic vulcanizate internal mixing and plasticizing device has been developed, which can automatically feed raw materials in a quantitative ratio, ensure the accuracy of the raw material ratio and improve the mixing efficiency of the bio-based thermoplastic vulcanizate. Utility Model Content

The utility model provides a bio-based thermoplastic vulcanizate internal mixing and plasticizing device which can automatically perform quantitative proportioning and feeding of raw materials, ensure the accuracy of raw material proportioning and improve the mixing efficiency of bio-based thermoplastic vulcanizate.

[0007] Preferably, an arc-shaped groove is formed on the lower side of the pressure plate.

[0008] Preferably, it also includes a material discharge box, a second connecting pipe, a third motor and a rotating column. The left and right material discharge boxes are connected to the rear side of the upper part of the connecting frame. The lower sides of the material discharge boxes are connected to the second connecting pipe. The left side of the left material discharge box is connected to the third motor. The second connecting pipe is rotatably connected to a rotating column. The rotating columns are rotatably connected to adjacent material discharge boxes. The output shaft of the third motor is connected to the left rotating column.

[0009] Preferably, it also includes a prompt wheel, a sensor and an impeller. The left part of the left rotating column is connected to the prompt wheel, the left part of the left discharge box is connected to the sensor, the sensor is located above the prompt wheel, the middle part of the rotating column is connected to the impeller, and the impeller is located inside the adjacent second connecting pipe.

[0010] Preferably, a display screen is also included, and the rear side of the left material box is connected with the display screen, and the sensor is connected to the display screen through an electric wire.

The display screen is connected to the second cylinder through electric wires. The sleeve is rotatably connected to the telescopic end of the second cylinder, and the rotating column is snap-fitted with the sleeve.

[0012] The beneficial effect of the utility model is that after the prompt wheel rotates a certain number of times, the display screen controls the start of the second cylinder, so that the sleeve moves to the left and disengages from the right rotating column, so that the right rotating column stops rotating, and then the right unloading box stops unloading, while the left unloading box continues unloading, thereby achieving the effect of automatically performing quantitative proportioning and unloading of raw materials, ensuring the accuracy of the raw material proportioning and improving the mixing efficiency of the bio-based thermoplastic vulcanizate.
