Abstract

The utility model provides a high-efficient continuous roller mill. Relates to a sand mixer, in particular to an improvement of a continuous sand mixer. Provides a continuous sand mixer with few material residues on the surface of a stirring blade. The stirring blade is arranged in a shell and is arranged on the side wall of the shell through a bearing assembly; the bearing assembly comprises a bearing support arranged on the side wall of the shell and a bearing body fixed on the bearing support, a buffer assembly is arranged between the bearing body and the bearing support, and the buffer assembly pushes the stirring blades to move in a reciprocating mode when the stirring blades are clamped. Drop the material from stirring vane through vibrations when the binder does not closely fix the material on stirring vane, just so can avoid remaining too much material on the stirring vane, guarantee to move smoothly at the stirring in-process.

Description

High-efficient continuous sand mixer

Technical Field

The utility model relates to a roller mill especially relates to a continuous roller mill's improvement.

Background

A continuous sand mixer refers to a sand mixer capable of continuously feeding and discharging. Commonly known as a packing auger. In the casting production, clay sand is modeled without using time limitation, and a roller type intermittent sand mixer is often adopted for mixing sand. The self-hardening sand is used for moulding, the usable time of the sand mixture is limited, a continuous sand mixer is usually selected, the raw sand is continuously supplied by a sand hopper, the adhesive and the curing agent are supplied by a liquid material pump, when the sand mixer is started, the raw sand and the liquid material are simultaneously supplied and are uniformly mixed within a few seconds, the sand mixture continuously flows out from a discharge port and directly flows into a sand box (core box) to complete filling of the sand box and vibration compaction within the usable time, and the core is manufactured. The continuous sand mixer is special sand mixing equipment for resin self-hardening sand and water glass self-hardening sand.

When the sand mulling device is used, due to the fact that the binder is added in the sand mulling process, after the sand mulling device is used for a long time, part of raw materials can be bound on blades of the packing auger by the binder, the packing auger rotates and is jammed, and sand mulling efficiency is affected. Therefore, a continuous sand mixer with few residues on the auger blade needs to be designed.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a few continuous sand mixer is remained to stirring vane surface material.

The utility model discloses a following technical scheme realizes: the efficient continuous sand mixer comprises a stirring blade arranged in a shell, wherein the stirring blade is arranged on the side wall of the shell through a bearing assembly;

the bearing assembly comprises a bearing support arranged on the side wall of the shell and a bearing body fixed on the bearing support, a buffer assembly is arranged between the bearing body and the bearing support, and the buffer assembly pushes the stirring blades to move in a reciprocating mode when the stirring blades are clamped.

The buffer assembly comprises a spring fixed at the top of the bearing support and an air cylinder fixed at the bottom of the bearing, and a stirring shaft of the stirring blade is arranged between the spring and the air cylinder.

The top end of the telescopic shaft of the air cylinder is provided with a bearing plate, the bearing plate is tightly attached to the outer ring of the bearing body, one end of the spring is fixed on the bearing support, and the other end of the spring is fixed on the outer ring of the bearing body.

Compared with the prior art, the utility model discloses utilize the buffering subassembly to drive stirring vane along the direction with stirring vane's axial looks vertically activity from top to bottom after the stirring is accomplished, stirring vane has slight vibrations in the activity process from top to bottom, drops the material through vibrations from stirring vane when the binder does not closely fix the material on stirring vane like this, just so can avoid stirring vane to go up to remain too much material, guarantees to move smoothly at the stirring in-process.

FIG. 2 is an enlarged schematic view of the utility model at A;

in the figure: 1. a housing; 2. a bearing body; 3. a bearing support; 4. a cylinder; 5. a spring; 6. a stirring blade.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

1-2, the high-efficiency continuous sand mixer comprises a stirring blade 6 arranged in a shell 1, wherein the stirring blade 6 is arranged on the side wall of the shell 1 through a bearing assembly; the bearing assembly comprises a bearing support 3 arranged on the side wall of the shell 1 and a bearing body 2 fixed on the bearing support 3, a buffer assembly is arranged between the bearing body 2 and the bearing support 3, and the buffer assembly pushes the stirring blades 6 to move in a reciprocating mode when the stirring blades 6 are clamped. Utilize the buffering subassembly to drive stirring vane 6 and move about from top to bottom along the axial looks vertically direction with stirring vane 6 after the stirring is accomplished, at the up-and-down activity in-process stirring vane 6 has slight vibrations, drops the material through vibrations from stirring vane 6 when the binder does not closely fix the material on stirring vane 6 like this, just so can avoid remaining too much material on stirring vane 6, guarantees to move smoothly at the stirring in-process.

The buffer assembly comprises a spring 5 fixed on the top of the bearing support 3 and a cylinder 4 fixed on the bottom of the bearing, and a stirring shaft of the stirring blade 6 is arranged between the spring 5 and the cylinder 4. The top end of the telescopic shaft of the air cylinder 4 is provided with a bearing plate, the bearing plate is tightly attached to the outer ring of the bearing body 2, one end of the spring 5 is fixed on the bearing support 3, and the other end of the spring 5 is fixed on the outer ring of the bearing body 2. Through the combination of cylinder 4 and

spring

5, 4 jacking stirring vane 6's (mixing) shafts of cylinder during use, when the whereabouts, spring 5 resets, bearing body 2 drives stirring vane 6 quick return, striking bearing board, realize small vibrations, drop the material through vibrations from stirring vane 6 when the binder does not closely fix the material on stirring vane 6, just so can avoid remaining too much material on stirring vane 6, guarantee to move smoothly at the stirring in-process.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
