Open-type rubber mixing mill with automatic distance adjusting function

Abstract

The invention discloses an open-type rubber mixing mill with an automatic distance adjusting function. The open-type rubber mixing mill comprises a base, wherein two mounting plates are fixedly connected with the upper side of the base; a first rotating shaft is rotationally connected with the opposite side walls of the two mounting plates; a first roller is arranged on the outer side of the first rotating shaft in a sleeving manner; openings are formed in the side walls of the mounting plates; placement blocks are slidably connected into the openings; the two side walls of each placement block are elastically connected with the two inner sides of the corresponding opening through a plurality of first springs correspondingly; two sliding cavities are formed in each mounting plate; sliding rods are slidably connected into the sliding cavities; and one end of each sliding rod is fixedly connected with the corresponding side wall of the corresponding placement block. The open-type rubber mixing mill is reasonable in structural design; under the action of the first springs, a second roller can move along with the change of the material volume, and then the sufficient extrusion of a material can be achieved; meanwhile, the open-type rubber mixing mill can be prevented from being damaged, the manual operation of working personnel is not needed, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of open rubber mixing machines, in particular to an open rubber mixing machine with automatic distance adjustment function. Background technique [0002] The open rubber mixing machine has two rollers arranged horizontally. The machine for rubber mixing between the two rollers, referred to as the open mill, is mainly composed of roller devices and transmission devices. Different linear speeds are pulled into the roller gap under the action of friction, and the material is strongly sheared and squeezed through the roller gap to increase the temperature of the material, thereby achieving the purpose of rubber mixing. It is mainly used in plastic refining, Kneading, tableting and heat refining and other operations. [0003] When the rubber mixer is working, the two rollers rotate in opposite directions to squeeze and masticate the material. When extruding materials with different volumes, the required distance...

AI Technical Summary

Problems solved by technology

[0003] When the rubber mixer is working, the two rollers rotate in opposite directions to squeeze and masticate the material. When extruding materials with different volumes, the required distance between the two rollers is also different. Common rubber mixer rollers are The distance is adjusted manually by the staff, so that when the adjustment distance is small, the distance between the two rollers is large, and the material cannot be fully squeezed, which affects the quality of the material. When the adjustment distance is large, the distance between the two rollers becomes smaller. It is easy to cause the two rollers to be squeezed too much and cause damage to the device
