Abstract

The utility model discloses an extrusion forming machine which can produce compact carbon profiled products. The utility model is characterized in that the distance between the equal section starting point (10) of the die bush (4) and the outlet (6) of the general extrusion forming machine is lengthened to form a die bush neck (5); when the extrusion forming machine works, the material in the die bush neck (5) is pressed again. The utility model can eliminate the cracks and interspaces in the products thus to form compact carbon profiled products.

Description

A kind of single lead screw ex truding briquetting machine

The utility model relates to a kind of extrusion equipment that uses in producing the carbon product process, especially referred to increase the single lead screw ex truding briquetting machine of long-neck die mould mouth.

The charcoal ink factory uses at present, and the single lead screw ex truding briquetting machine under the prior art condition is made up of three parts such as housing, extrusion piston, die mould mouths.Through the raw material of precompressed, under the promotion of piston, extrude in the single lead screw ex truding briquetting machine feed bin, form the die mould product through the die mould mouth.The die mould mouth neck length of this single lead screw ex truding briquetting machine is generally less than product length.The raw material that enters is here directly pushed away.The product inside that produces with it exists crackle, space, the product leakiness.

The purpose of this utility model provides a kind of single lead screw ex truding briquetting machine, and it can squeeze out closely knit die mould product.

The purpose of this utility model is to realize like this.Make the long-neck die mould mouth of a kind of length, will have die mould product pressurization again in the die mould mouth in crackle, space, eliminate its inner crackle, space, make product closely knit greater than one times or a few multiplication of voltage type product lengths.

Specific practice is: increase interior uiform section starting point of single lead screw ex truding briquetting machine die mould mouth and the length between the discharging opening, form die mould mouth neck.Its length is greater than the die mould product length of a times or several times, and the inner section form that increases part is identical with the discharging opening section form.The press other parts move with the lengthening of extrusion modling mouth.During single lead screw ex truding briquetting machine work, the raw material through precompressed in the single lead screw ex truding briquetting machine feed bin is clamp-oned the forming nozzle neck by piston, at this moment, has crackle, space between the feed particles.When such raw material is pressed against the discharging opening place of die mould mouth, stop extruding, close the discharging opening of die mould mouth, afterwards pressurization again.At this moment the crackle, the space that are in the material of die mould mouth neck are compacted.Open die mould mouth discharging opening, extruding again, at this moment, the product that extruding is come out is closely knit.Repeat said process, can produce a large amount of closely knit products.

Compare with the prior art single lead screw ex truding briquetting machine, owing to increased the length of die mould mouth neck, electrode die mould product is pressurizeed once more at the forming nozzle neck, has eliminated internal fissure, the space of product.Use it can produce closely knit product.Increase the length of die mould mouth neck, the whole relatively press increase of its expense seldom.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the fundamental diagram of embodiment single lead screw ex truding briquetting machine.

In operation principle Fig. 1, piston [1] is positioned at the feed bin [3] that housing [2] surrounds, and die mould mouth [4] closely links to each other with housing [2], and the uiform section starting point [10] of die mould mouth neck [5] is a charging aperture, and the other end is discharging opening [6], and striker plate [7] is adjacent with discharging opening [6].The length of die mould mouth neck [5] is greater than one times or several times of the die mould product length, and its inner section form is identical with discharging opening [6] inner section form.Like this, after the inside raw material of die mould mouth neck [5] pressurizeed once more, can obtain complete die mould product, die mould mouth neck [5] is long more, and extruder output is big more.During extruder work, close striker plate [7], start raw material [8] and the interior raw material [9] of die mould mouth neck [5] in piston [1] the pressurization feed bin, stop pressurization, open striker plate [7], start piston [1], raw material in the feed bin [3] is squeezed into die mould mouth neck [5], the raw material of die mould mouth neck [5] is extruded, and after pressing certain-length and disconnecting, forms product.The raw material inside that enters die mould mouth neck [5] has crackle, space, if directly extruded, and the product leakiness that obtains; The utility model pressurizes once more to it, can obtain closely knit die mould product.

Claims

A kind of single lead screw ex truding briquetting machine comprises die mould mouth [4] etc., it is characterized in that the uiform section starting point [10] of die mould mouth [4] and the distance lengthening between outlet [6], forms die mould mouth neck [5], and the raw material that is in the die mould mouth neck [5] is pressurized again, compacting.
