Description

A kind of plunger type banded extruder

Technical field

The utility model relates to a kind of former, especially a kind of plunger type former that is used for Powdered or pasty material moulding.

Background technology

Often need in the industrial production material of Powdered or pasty state is carried out forming processes.In the Preparation of catalysts process,, need to use suitable extrusion equipment in order to obtain the catalyst of difformity, size; During the laboratory development catalyst, often use small-sized batch (-type) extrusion equipment; Common screw propulsion banded extruder owing to reasons such as treating capacity is big, complicated operations, generally is not suitable for the laboratory and uses.

In the prior art, Chinese patent CN20316211U provides a kind of plunger type banded extruder, it is characterized in that: in cylindrical shell, adorn a lining, place the plunger in the lining to be connected with augering screw, by the augering screw that rotation is attached thereto, drive plunger parallel moving in lining simultaneously, with pressing materials, make it by the perforate on the orifice plate, be shaped to required bar.

Chinese patent CN2128464Y provides a kind of plunger type banded extruder, it is characterized in that: be power with the jack, drive by top board and to move on pull bar and barrel, the plunger or glide, exert pressure to material in the barrel, make material pass through the orifice plate extrusion modling along the plunger that barrel glides.

In above-mentioned two kinds of batch (-type) extrusion equipment, the part that contacts with material is movable part, can dismantle easily, clean.But in the extrusion process, material filling and plunger location process are loaded down with trivial details, and the plunger locating accuracy is low, and the whole extrusion process of hand-guided causes the said equipment to use inconvenience in addition.

Summary of the invention

Exist in the prior art in order to solve: material loads that process is loaded down with trivial details, the plunger positioning accuracy is low and problem such as hand-guided extrusion process, and the utility model: the barrel that adopts opening to make progress has made things convenient for the filling of material; Utilize positioner, simplified the plunger position fixing process and improved positioning accuracy; Utilize axially stop block to cooperate other control systems, realized the automatic control of extrusion process, improved operating efficiency.

A kind of plunger type banded extruder of the present utility model is achieved in that

A kind of plunger type banded extruder comprises: barrel, orifice plate, plunger is characterized in that:

Barrel is installed on the barrel support, and the barrel support is installed on the column by locator, and described locator restriction barrel support is the rotational angle of axle with the column; Plunger is installed in the lower end of augering screw, and axially stop block is installed on augering screw, and described axially stop block restriction augering screw is in axial moving range; Propulsion plant is installed on the roof support, and roof support is installed on the column.

When concrete the use, the barrel support is connected by socketing bar with roof support.

The opening direction of barrel up, the extrusion material of being convenient to pack into; The shape of orifice plate perforate can be shapes such as circle, ellipse, trilobal, annular or honeycombed, to satisfy different shaping of catalyst requirements; Augering screw is driven by propulsion plant, and drives connected plunger and move axially in barrel, and plunger is exerted pressure to the material in the barrel, and material is by the orifice plate extrusion modling.

Adopt movable connection method between plunger and augering screw, barrel and barrel support, orifice plate and the barrel, the parts that plunger, barrel, orifice plate etc. contact with material can be dismantled easily, clean.

Utilize locator, can locate barrel rapidly and accurately, make the dead in line of barrel and plunger, guarantee both concentricitys.When the filling material, the barrel support can be a rotating certain angle with column, makes the filling of material convenient; Locator plays the effect that original position and rotational angle size are rotated in restriction, because the position of propulsion plant is fixed, the original position of utilizing the default barrel support of locator to rotate makes the dead in line of the axis and the plunger of barrel, realizes quick and precisely locating the purpose of barrel.

When needs filling material, at first the rotating function of locator to be opened, the barrel support is begun to rotate an angle to a side by original position, and this angle can be default by locator, is generally 90 degree, and purpose is the filling that makes things convenient for material; After filling is finished, the barrel support is resetted,, therefore can locate barrel rapidly and accurately because its initial position is predefined, and just in time makes the dead in line of barrel and plunger; Behind the barrel location, the locator rotating function is locked, the action of beginning extrusion.

The propulsion plant motor-driven.The axially stop block of installing on augering screw has limited the moving range of augering screw on axis direction; During extrusion, augering screw is moved down into default position, and axially stop block sends signal, and the direction of motion by control device change augering screw moves upward it, avoids because the orifice plate that the excessive compression of augering screw causes damages.Axially stop block cooperates other control systems, can realize the automatic control of extrusion process.

During extrusion, plunger is applied to the thrust on the material, and can cause the barrel support is that rotate in vertical plane at the center with the tie point of itself and column, and the miniature deformation of generation can destroy overlapping of barrel and plunger axis, for overcoming this shortcoming, between barrel support and roof support, be provided with and socket bar.Socket bar and can pass through bolting, make things convenient for installation and removal.

The utility model banded extruder has following characteristics:

1. the parts that contact with material such as plunger, barrel and orifice plate can be dismantled, the convenient cleaning.

2. utilize locator, guaranteed the concentricity of barrel and plunger, made things convenient for the filling of material and the location quick and precisely of barrel.

3. utilize axially stop block, set the plunger movement scope, avoid too pushing barrel and orifice plate; Cooperate control device, realize the automatic control of extrusion process.

4. be provided with between barrel support and the roof support and socket bar, can improve crushing strength, overcome the disadvantage that plunger easily blocks, and guarantee that orifice plate is stressed evenly, improved the quality of extrusion.
