Technical Field
[0001] This utility model relates to the technical field of rubber and plastic processing equipment, and specifically to a new type of labor-saving mixing mechanism for a mixing mill. Background Technology
[0002] For the purpose of recycling materials, internal mixers are widely used production equipment in the current plastics industry. The mixing chambers in the internal mixer are supported by the connection between the mixing shaft and the bearing housing. During the rubber mixing process, the bearing housing not only needs to bear the weight of the mixing chamber, but also needs to ensure the long-term lubrication and rotation of the mixing shaft, which places extremely high demands on the bearing performance inside the bearing housing.
[0003] Currently, both tilting bucket internal mixers and drop-type internal mixers use a single bearing structure in their internal mixing bearing housings. For internal mixing chambers of different sizes or at different internal mixing speeds, a single bearing bears the load. Under the influence of gravity and high-speed rotation, the lifespan of the bearing inside the bearing housing will decrease sharply, making it impossible to achieve high-speed internal mixing and feeding, thus affecting the normal operation of the equipment.

Its structure is reasonably designed.

The side wall panels are in two pieces, respectively disposed on both sides of the mixing chamber. The bearing seats are disposed on the sides of the side wall panels, and the lower support is disposed at the lower part of the bearing seats. A stirring main shaft and a passive stirring shaft are disposed inside the mixing chamber, both penetrating both sides of the mixing chamber to the bearing seats. The gearbox is disposed between one end of the stirring main shaft and the passive stirring shaft. Stirring blades are disposed on the stirring main shaft and the passive stirring shaft inside the mixing chamber.
[0007] The bearing housing is equipped with a first bearing and a second bearing. The two ends of the stirring main shaft are movably connected to the bearing housing through the first bearing and the second bearing. The two ends of the passive stirring shaft are movably connected to the bearing housing through the first bearing and the second bearing.
[0008] Furthermore, the bearing housing contains at least two bearings.

[0010] Furthermore, the bearing seats on both sides of the mixing chamber are symmetrically arranged.
[0011] Furthermore, the connection between the stirring spindle and the side wall plates on both sides is equipped with a sealing device.
[0012] Furthermore, the passive stirring shaft is equipped with a sealing device at the connection point with the side wall panels on both sides.
[0013] The beneficial effects of this utility model are:
[0014] A novel labor-saving internal mixer mechanism includes a mixing chamber, side wall plates, bearing housings, a gearbox, and a lower support.
