Cylinder supporting frame of plastic extruder

Abstract

The invention discloses a cylinder supporting frame of a plastic extruder. The cylinder supporting frame comprises a support and a connecting piece, wherein the connecting piece is positioned above the support and is fixedly connected with a cylinder of the plastic extruder, and the support is movably connected with the connecting piece. The cylinder of the plastic extruder is fixed on the connecting piece on the upper part of the supporting frame, and can be supported by certain height through the supporting frame, and thus production requirements are met; meanwhile, the support of the supporting frame is movably connected with the connecting piece, when the cylinder of the plastic extruder is expanded by heating in an operation process, the connecting piece can move in a horizontal direction along the size variation of the cylinder of the plastic extruder, and at the moment, as the connecting piece and the support are in flexible connection, the support can not move along the connecting piece, and can not transform under the heating expanding action of the cylinder of the plastic extruder; therefore, the cylinder supporting frame of the plastic extruder provided by the invention has the characteristics that the service life is long, the work efficiency is high, and the practicability is high.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a support frame. Background technique [0002] Plastic extruders are widely used in the processing and molding of plastics. During the use of plastic extruders, they are generally required to reach a certain height for easy operation. Support frame, the existing plastic extruder cylinder support frame is generally made of base and the fixed arm that is located on the base, and this fixed arm is directly fixedly connected with machine barrel with bolt or screw. During the working process, the plastic extruder barrel is often heated to 100-150°C. At this time, for large and medium-sized plastic extruders, the total expansion length of the barrel usually increases by 10-15mm or more, so in the plastic extruder Under the rigidly connected structure of the barrel and the support frame, the huge expansion force of the barrel of the plastic extruder usually deforms the support frame on the one ha...

Problems solved by technology

During the working process, the plastic extruder barrel is often heated to 100-150°C. At this time, for large and medium-sized plastic extruders, the total expansion length of the barrel usually increases by 10-15mm or more, so in the plastic extruder Under the rigidly connected structure of the barrel and the support frame, the huge expansion force of the barrel of the plastic extruder usually deforms the support frame on the one hand, which makes the service life of the support frame short and the maintenance workload is large; on the other hand , which also makes the production stability of the plastic extruder poor, making it difficult to achieve high-speed and efficient production
