Abstract

The utility model discloses a circular groove brick extruding machine, which comprises a roller, a shell, a mud pressing roller, a mud scraping blade and a power plant, wherein a feeding port and a discharge port are arranged on the shell, the mud pressing roller is arranged adjacent to the feeding port in the shell, the roller is arranged in the shell, the roller is matched with the mud pressing roller in a rolling way, a plurality of annular grooves are arranged on the arc surface of the roller, one end of the mud scraping blade is arranged in one annular groove, the other end of the mud scraping blade is fixed on the shell adjacent to the discharging port, and the power plant is connected with the roller. The utility model has the advantages that: the extruding efficiency is higher, the mud heating phenomenon is rarely caused, mud strips with uniform quality can be obtained, the wear is low, and products with wide sizes can be formed.

Description

A kind of annular groove extruder

Technical field

The utility model relates to a kind of annular groove extruder.

Background technology

Existing extruder mostly is the spiral extruder, adopt screw rod that pug is extruded from discharging opening, spiral is extruded more or less to exist and is extruded spiral lamination stress, changing soft mould or during semi-stiff extrusion, do suitable variation to pitch, structure, joint number and the mud cylinder length of screw reamer, the goods of the very wide size of very difficult moulding are along on the height and width of the outlet of machine mouth, mud bar different parts has different extruded velocities, thereby has bigger moulding stress.

The utility model content

The purpose of this utility model is to provide a kind of annular groove extruder, can effectively solve the problem of the goods that existing spiral extruder extrusion efficiency is low, pug generates heat the very wide size of serious, the difficult moulding of phenomenon.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of annular groove extruder, comprise roller, shell, press the mud roller, scrape trowel, power set, have charging aperture and discharging opening on the described shell, by the described pressure mud roller setting charging aperture in the enclosure, described roller setting in the enclosure, described roller cooperates with pressing the rolling of mud roller, have some ring-shaped grooves on the curved surfaces of described roller, a described end of scraping trowel is arranged in the ring-shaped groove, the described other end of scraping trowel is fixed on the other shell of discharging opening, and described power set link to each other with roller.

Preferably, the cross section of described ring-shaped groove is a rectangular channel; Can make the better moulding of the pug of extruding.

Preferably, described power set comprise reductor and motor, and described motor drives roller by reductor and rotates; Improve output torque during the reductor reduction of speed, reduce the inertia of load simultaneously.

Compared with prior art, the utility model has the advantages that:

1. higher extrusion efficiency is arranged, can reach 70-80%, and the spiral extruder generally can only reach 25-35%;

2. the heating phenomenon of pug seldom occurs, also the caloric value more than the spiral extruder is little even its caloric value of heating phenomenon is arranged;

3. along on the height and width of whole machine mouth outlet, mud bar different parts all has identical extruded velocity, thereby can obtain the uniform mud bar of inherent quality;

4. it is low to wear and tear: pug is to carry by annular groove, is being no pressure and friction free for one section than length between them, only just occurs friction by scraping trowel to extruding by annular groove at pug;

5. can extrude the adobe shortening drying time of production than spiral,, limit the shortening of drying time because the adobe that spiral is extruded all more or less exists moulding stress;

6. goods that can the very wide size of moulding as width 600～700mm, because it has the roller of broad, therefore can extrude the batten brick, even it is passable too to extrude the less goods of width, because can extrude two or more mud bar.

Description of drawings

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the stereogram of a kind of annular groove extruder of the utility model except that power set.

The specific embodiment

Consult Fig. 1, Fig. 2, Fig. 3 is the embodiment of a kind of annular groove extruder of the utility model, a kind of annular groove extruder, comprise roller 1, shell 2, press mud roller 3, scrape trowel 4, power set, have charging aperture 21 and discharging opening 22 on the described shell 2, the charging aperture 21 that described pressure mud roller 3 is arranged in the shell 2 is other, described roller 1 is arranged in the shell 2, described roller 1 cooperates with pressing 3 rollings of mud roller, have some ring-shaped grooves 11 on the curved surfaces of described roller 1, a described end of scraping trowel 4 is arranged in the ring-shaped groove 11, the described other end of scraping trowel 4 is fixed on the shell on discharging opening 22 sides, described power set link to each other with roller 1, the cross section of described ring-shaped groove 11 is a rectangular channel, and described power set comprise reductor 5 and motor, and described motor drives roller 1 by reductor 5 and rotates.

Pug is poured into from charging aperture 21, through overvoltage mud roller 3 with the pug compacting in ring-shaped groove 11, when pug moves to discharging opening 22 places, pug is separated from ring-shaped groove 11 by scraping trowel 4, make pug enter discharging opening 22 extrusion moldings.Higher extrusion efficiency is arranged, and the heating phenomenon of pug seldom occurs, the mud bar of extruding is very even, and the embryo brick is short drying time, and the system molded dimension is wide.

The above only is a specific embodiment of the utility model, but technical characterictic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
