Abstract
The utility model relates to brick making equipment, in particular to a bidirectional brick extruder without a reamer. The bidirectional brick extruder solves problems of low forming rate of products, troublesome operation, narrow application range, low extrusion efficiency and the like of an existing spiral brick extruder. The bidirectional brick extruder comprises a shell, a feed inlet and discharge outlets are arranged on the shell, a forming roller and a pressing roller are mounted in the shell, a plurality of annular forming grooves are respectively arranged on an arc-shaped surface of the forming roller and an arc-shaped surface of the pressing roller at intervals, the annular forming grooves on the forming roller are staggered with the annular forming grooves on the pressing roller, and cutters are fixedly arranged in the shell, are positioned at the discharge outlets and extend into the annular forming grooves. The bidirectional brick extruder has the advantages that the bidirectional brick extruder is simple in structure, reasonable in design and high in extrusion efficiency, can be operated easily and conveniently and has certain popularization value, mud strips extruded by the bidirectional brick extruder are uniform, the green brick drying time is short, the internal density of each obtained green brick is uniform, internal stress on each green brick is low, cracks caused by uneven contraction of the green bricks during drying are effectively prevented, the extrusion efficiency is greatly improved, and the productivity is enhanced.
Description
Technical field
The utility model relates to a kind of brick equipment, is specially a kind of without the two-way extruder of reamer.
Background technology
Existing extruder mostly is greatly the spiral extruder, adopts screw rod that pug is extruded from discharging opening, and the spiral squeezing meeting is so that the goods internal stress is larger, internal density is inhomogeneous, when carrying out drying in the later stage, easily shrinks inhomogeneous, produce the crack, reduce the ratio of briquetting of goods, and changing soft mould or during semi-stiff extrusion, to do suitable variation to pitch, structure, joint number and the mud cylinder length of screw reamer, complex operation, narrow application range, in addition, extrusion efficiency is lower, and labour intensity is large.
Summary of the invention
The problems such as the utility model exists in order to solve existing spiral extruder that the product molding rate is low, complex operation, narrow application range and extrusion efficiency are low provide a kind of without the two-way extruder of reamer.
The utility model is to adopt following technical scheme to realize: without the two-way extruder of reamer, comprise shell, cover top portion is provided with charging aperture, the shell both sides are respectively equipped with discharging opening, install in the shell shaping roller that is driven by power set and cooperate with shaping roller roll roller, shaping roller and roll on the curved surfaces of roller all that the interval has some annular forming tank wherein, the interlaced setting of annular forming tank on two rollers, in the shell and be positioned at two discharging opening positions and be fixed with respectively cutting knife, cutting knife stretches in the annular forming tank of corresponding roller.
Described annular forming tank cross section is rectangle, can make to extrude the better moulding of pug.
Adopt structural design of the present utility model, pug is delivered to shaping roller and rolls in the annular forming tank of roller, because shaping roller and roll the interlaced setting of annular forming tank on the curved surfaces of roller, utilize mutual extruding between the two, can obtain quality evenly, the more uniform mud bar of internal density, utilize cutting knife that the mud bar is cut off one by one at the discharging opening place, obtain adobe.
Compared with prior art, the utility model is simple in structure, reasonable in design, easy and simple to handle, and the mud bar of extruding is very even, the brick bat drying time is short, higher extrusion efficiency is arranged, and gained adobe internal density is more even, internal stress is little, prevented that effectively adobe from shrinking inhomogeneous and crack that produce when drying, in addition, because shaping roller and milling roller tube outer surface are equipped with annular forming tank, can greatly improve extrusion efficiency, boost productivity, have certain promotional value.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is shaping roller described in the utility model and the structural representation that rolls roller;
Among the figure: the 1-shell; The 2-charging aperture; The 3-discharging opening; The 4-power set; The 5-shaping roller; 6-rolls roller; 7-annular forming tank; The 8-cutting knife.
The specific embodiment
Without the two-way extruder of reamer, such as Fig. 1, shown in 2, comprise shell 1, cover top portion is provided with charging aperture 2, the shell both sides are respectively equipped with discharging opening 3, install in the shell shaping roller 5 that is driven by power set 4 and cooperate with shaping roller roll roller 6, power set can comprise motor and decelerator, shaping roller and roll on the curved surfaces of roller all that the interval has some annular forming tank 7 wherein, the interlaced setting of annular forming tank on two rollers, in the shell, and be positioned at two discharging opening positions and be fixed with respectively cutting knife 8, cutting knife stretches in the annular forming tank of corresponding roller.Annular forming tank 7 cross sections are rectangle, and the degree of depth of annular forming tank and width can require to determine according to green brick forming.
Pug is poured into from charging aperture, enter shaping roller and roll in the annular forming tank of roller, because shaping roller and roll the interlaced setting of annular forming tank on the curved surfaces of roller, utilize mutual extruding between the two to carry out moulding, when pug moves to the discharging opening place, by cutting knife pug is separated from annular forming tank, make pug enter the discharging opening extrusion molding.
Claims (2)
1. one kind without the two-way extruder of reamer, comprise shell (1), cover top portion is provided with charging aperture (2), the shell both sides are respectively equipped with discharging opening (3), it is characterized in that installing in the shell shaping roller (5) that is driven by power set (4) and cooperate with shaping roller roll roller (6), shaping roller and roll on the curved surfaces of roller all that the interval has some annular forming tank (7) wherein, the interlaced setting of annular forming tank on two rollers, in the shell, and be positioned at two discharging opening positions and be fixed with respectively cutting knife (8), cutting knife stretches in the annular forming tank of corresponding roller.
2. according to claim 1 without conic reamer brick extruder, it is characterized in that annular forming tank (7) cross section is rectangle.
