Description

Rotary brickmaking machine

The utility model is that a kind of power-actuated, screw rod advances the extruding feeding to be shaped, and can realize the brickmaking machine of single adobe demoulding.

Used brickmaking mechanical is to adopt screw rod to advance extrusion molding basically, but is mostly pug is squeezed into the thick adobe of strip, again through manually cutting into the monolithic adobe.Such machinery production line length, floor space is big, operates cumbersomely, and labour intensity is big, and production efficiency is low.Moreover, such machinery requires big to the water content that adds pug, to increase the viscosity of pug, be convenient to extrusion molding,, also need consider on the perisporium of shape mould shape chamber back segment, the water spray aperture to be set for guaranteeing the smooth demoulding after moulded pottery not yet put in a kiln to bake is shaped, in case which side aperture plug resistance, then this limit shape chamber demoulding is not smooth, and the thick adobe that can cause is out of shape, thereby influences the quality of made adobe.

The purpose of this utility model is, designs a kind of the propelling with screw rod and is squeezed into monolithic adobe and the rotation by finishing die, realizes the brickmaking mechanical that adobe ejects simultaneously, overcomes above-mentioned deficiency.

Its objective is such realization, this brickmaking machine comprises frame, be contained in feed cylinder above the frame, be contained in above the feed cylinder rear end and the cast hopper that communicates with feed cylinder, be sleeved on the augering screw in the feed cylinder, the afterbody of augering screw, it is one section stepped cylinder axis, this position at interval 2 through the bearing clamping on frame, duplex or two-stage driving gear are installed therebetween, and the column part of the rear of axle links to each other with decelerator and motor through shaft coupling.The key of this machine is, is provided with a widely different finishing die that revolves body at the front end of feed cylinder, has at least four uniform forming cavity on its front end face, and the center of forming cavity is corresponding with the feed cylinder center.The back side of finishing die is driven gear coaxial mounted with it, transition gear engagement, another transition wheel gear on the power transmission shaft other end and the engagement of the one-level driving gear on the augering screw on this gear and its below power transmission shaft one end.In the forming cavity of finishing die, the knock-pin that matches with forming cavity is housed, an edge cam is equipped with in the knock-pin rear end, when rotating to, forming cavity throws off feed cylinder angle phase position place, the knock-pin tail end touches mutually with the edge cam peak, and at this moment, knock-pin ejects the adobe in the forming cavity.

This brickmaking machine compact conformation, novelty, easy to operate, easy, can guarantee output quality effectively, and labour intensity is little, save the labour, the production efficiency height, easy to maintenance, quick.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the main structure cutaway view according to the brickmaking machine that the utility model proposes.

Fig. 2 is the vertical view according to the brickmaking machine that the utility model proposes.

Below in conjunction with Fig. 1,2 details and the working conditions that describe in detail according to the concrete brickmaking machine that the utility model proposes.

This brickmaking machine comprises frame [1], be contained in the feed cylinder [15] above the frame, be contained in above the feed cylinder rear end and the cast hopper that communicates with feed cylinder [8], be sleeved on the augering screw [2] in the feed cylinder, the afterbody of augering screw, be stepped cylinder axis, this position at interval 2 through radial-thrust bearing [3], [16] clamping is on frame, for preventing this axial float at work, at the rear portion of bearing [16] end face bearing [17] is installed side by side, between the two bearings supporting-point, two-stage driving gear [4] is installed, [5], the column part of this rear links to each other with motor with decelerator through shaft coupling [22].Front end at feed cylinder is provided with a widely different finishing die [9] that revolves body, on its front end face, has four uniform forming cavity, and the pivot of this forming cavity is corresponding with the feed cylinder center.The back side of finishing die is coaxially installed with driven gear [10] with it, this take turns with its below power transmission shaft [19] one ends on transition gear [20] engagement, the transition wheel on the power transmission shaft other end [18] is with driving gear [4] engagement on the augering screw.In the forming cavity of finishing die, be set with the knock-pin [11] that matches with forming cavity, the back bar of knock-pin passes finishing die and driven gear, and touch mutually with the edge cam that is contained in its rear end [13], when forming cavity rotates to the suitable angle phase position of disengagement feed cylinder, masthead corrects with the peak of edge cam and touches mutually behind the knock-pin, and at this moment, knock-pin just pushes up the adobe of making in the forming cavity from the shape chamber.For reducing the friction between knock-pin and edge cam, the bar tail end has radial groove behind knock-pin, is installed with contact roller [12] in it.Excessive for the interval that prevents grooving and feed cylinder front end face, on the excircle of finishing die, be processed with a ring annular groove, and at this circumference place uniform three the spacing cards [14] that are provided with, the latch on it is held in the cannelure.In the lower end of cast hopper, two reinforced axles arranged side by side [6] are housed in the same way with augering screw, a driven gear [7], [21] respectively are equipped with in its rear end, two-wheeled and driving gear [5] engagement, on one section axle of diaxon in cast hopper, interlaced multiple stage crushing double wedge and the charging scraper plate of being equipped with.The working condition of this machine is as follows, when the motor-driven augering screw rotates, the two-stage driving gear of its rear end drives the reinforced axle rotation in finishing die and the cast hopper simultaneously, earth in the cast hopper that adds, broken double wedge on the reinforced axle of quilt smashes and falls in the feed cylinder, and push through augering screw, send to and become adobe in the forming cavity, adobe after being shaped, when forwarding the disengagement feed cylinder to certain angular position to finishing die, knock-pin tail end in the forming cavity just in time touches mutually with the edge cam peak, and then adobe is ejected masthead and goes out forming cavity, circulates with this and realizes the brickmaking process.
