Description

Technical Field

[0001] The utility model relates to a limiting mechanism of an internal mixer and belongs to the field of internal mixers. Background Art

[0002] Closed plastic refining machine is referred to as internal mixer. The main component of internal mixer is internal mixing chamber, also called plastic refining chamber, with feeding device at the top and unloading device at the bottom, and a bolt at the top and bottom; when the top bolt and the bottom bolt are closed, a closed plastic refining chamber is formed. There is a pair of rotors rotating in opposite directions in the plastic refining chamber, the rotor cross section is pear-shaped, and it is a Z-shaped spiral along the longitudinal direction. The rotor speed is slightly different, and there is a constant speed ratio between the rotors and between the rotors and the inner wall of the plastic refining chamber. There is a cooling (heating) jacket on the outer wall of the plastic refining chamber to heat and cool the material. In order to prevent the roller driving the rotor from being worn, the existing mechanism for limiting the rotor of the internal mixer is equipped with a rubber pad structure at the driving end of the limiting mechanism, but it often needs to be replaced frequently, which is inconvenient. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a limiting mechanism of an internal mixer, whose structure includes a limiting cylinder, a connecting seat is connected to the output end of the limiting cylinder, a limiting plate is provided at the end of the connecting seat away from the limiting cylinder, an assembly notch is provided in the middle of the end of the limiting plate away from the connecting seat, a thickened limiting pad is movably provided in the assembly notch, a transmission plate is bonded to the bottom surface of the thickened limiting pad by PET glue, a driving cavity is provided in the connecting seat, an electric cylinder is provided in the driving cavity, the output end of the electric cylinder extends into the assembly notch and is connected to the transmission plate, an induction patch is provided at the bottom outer side of the thickened limiting pad, an infrared sensor is provided on the inner wall of the assembly notch, and a warning light electrically connected to the infrared sensor is provided on the outer wall of the limiting plate.

[0005] Furthermore, a control panel for controlling the operation of the electric cylinder is provided on the outer wall of the connecting seat.

[0006] Furthermore, the thickened limiting pad is made of rubber material, and the end surface of the thickened limiting pad has a curvature.

[0007] Furthermore, the sensing patch is located obliquely below the infrared sensor.

[0008] Furthermore, a battery structure for supplying power to the infrared sensor and the warning light is provided in the limit plate.

[0009] The beneficial effects of the utility model are as follows: the thickened limit pad is adopted, and the durability is effectively improved through the structure of automatically pushing the reset, and a replacement prompt structure is also provided to help the staff to replace it in time. When working, the limit cylinder installed at the rotor of the internal mixer is operated, and its output end is extended to drive the limit plate, and the thickened limit pad exposed on the limit plate limits the positioning of the driving roller on the rotor. When the thickened limit pad is worn to a certain extent, the control panel is operated to make the electric cylinder drive the transmission plate to move a stroke, and the transmission plate drives the thickened limit pad to expose the limit plate again. When the induction patch on the thickened limit pad is detected by the infrared sensor, the warning light is on, prompting the staff to replace the thickened limit pad in time.
