Description
Technical Field
[0001] The utility model relates to the technical field of roller presses, in particular to a novel roller sleeve device for a roller press. Background Art
[0002] The roller press is designed based on the principle of bed grinding. Its main features are: high pressure, full speed, full material, and bed crushing. The roller press consists of two extrusion rollers that rotate synchronously in opposite directions, one is a fixed roller and the other is a movable roller. The material is fed from above the two rollers and is continuously brought into the roller space by the extrusion rollers. After being subjected to a high pressure of 100-150MPa, it becomes a dense cake and is discharged from the bottom of the machine.
[0003] The existing Chinese utility model patent with reference number CN212684795U discloses a novel roller sleeve device, comprising a roller sleeve, a roller shaft and a limiting mechanism, wherein the roller sleeve is sleeved on the roller shaft, the limiting mechanism is sleeved on the roller shaft, the limiting mechanism comprises a fixing plate, a limiting rod and a clamping assembly, the clamping assembly is detachably sleeved on the roller shaft, the fixing plate is vertically fitted on the axial surface of the roller sleeve, and fixing protrusions are fixed on the front and rear surfaces, the fixing protrusions are fixed to the axial surface of the roller sleeve by screws, the limiting rod is installed at the free end of the fixing plate, and can be screwed together with the clamping assembly for limiting position, the clamping assembly comprises an arc plate, a fixing lug and a connecting bolt; the utility model is provided with a limiting mechanism, which can fix and limit the roller sleeve in the axial direction of the original positioning pin limit, thereby relatively reducing the degree of axial slippage of the roller sleeve, thereby reducing the factors affecting the sudden stop of the roller press, and the entire mechanism is convenient to install and disassemble without affecting the normal use of the roller sleeve.
[0004] Since the roller press needs to apply a force directed towards the fixed extrusion rod to the movable extrusion rod, in order to ensure that the extrusion rod does not deform under the force, the existing extrusion rod is generally a solid structure. Since the surface of the extrusion rod will wear out with use, the cost of replacing the extrusion rod in this way is high. At the same time, the extrusion rod needs to rotate during use. Generally, a bearing is used to limit the position of the extrusion rod while allowing the extrusion rod to rotate. In order to ensure the effect of the bearing, the bearing and the extrusion rod need to be fully fitted, which makes it very inconvenient to disassemble and assemble the extrusion rod.
