Abstract

The utility model relates to an improved butting roller extruding apparatus and belongs to the field of the extruding apparatus. The improved butting roller extruding apparatus is composed of a pulp storing barrel, an upper roller, a lower roller, a guiding roller, a tooth wheel and a triangle zone wheel, wherein, one end of the upper roller is provided with the tooth wheel. One end of the lower roller is provided with the triangle zone wheel, and the guiding roller and the upper roller is driven by the tooth wheel. The guiding roller and the lower roller are driven by a telescopic leather belt, and the lower roller can move up and down. The improved butting roller extruding apparatus can cause the two processes of organic foam immersing pulp material and extruding the excrescent pulp material to be carried out simultaneously, and the flow rate of the pulp material can be regulated through a sliding piece in the exiting port passage of the lower end of the pulp storing barrel. The improved butting roller extruding apparatus can meet the immersion molding needs of different dimensions of organic foam bodies.

Description

A kind of improved pair roller pressurizing unit

The utility model relates to a kind of pair roller pressurizing unit, and it is mainly used in the dip forming that organic foam body impregnation technology prepares screen like and porous ceramic, also can be used for the extrusion forming of other goods, belongs to the pressurizing unit field.

Foam impregnation technology is a kind of technology of producing the mesh-type porous ceramics with the three-dimensional netted skeleton structure of perforate.The characteristics of this technology are the special constructions that has relied on the three-dimensional netted skeleton of perforate that the organic foam body had, and the slurry for preparing is flooded organic foam web shape body, extrude unnecessary slurry, burn the organic foam body after the drying and obtain a kind of screen like and porous ceramic.Wherein extruding unnecessary slurry is the critical stage of volume density, gas permeability and the porosity of decision porous article.In order to control the density of what and the goods of extruding slurry, generally adopt the pair roller extrusion to get rid of unnecessary slurry, and require the pair roller spacing to regulate.The adjusting of relative motion between the pair roller and pair roller spacing, traditional pressurizing unit are can allow the tooth top of a gear and the tooth root of another gear to exist realize certain intermittence when coming transmission and dependence two gears engaged by gear.Therefore, the adjustable distance of its pair roller spacing is very limited, is difficult to satisfy the requirement of moulding than the thick stock body.

The purpose of this utility model provides a kind of improved pair roller pressurizing unit.It not only can make the foam impregnation slurry and extrude unnecessary two step of slurry process carries out simultaneously, and the flow of slurry can be regulated by the slide plate of containing in the exit passageway of slurry bucket lower end.

The purpose of this utility model is achieved in that in device except having up and down two rollers, also disposes a deflector roll.Deflector roll is as drive roll, and up-down rollers is a driven voller, and by gear drive, and lower roll is driven by deflector roll by rubber belt between top roll and the deflector roll.Belt transmission is transmission in the same way, thereby has guaranteed that the motion of two rollers up and down is relative motions.Lower roll can move up and down and regulate, and rubber belt has certain elasticity, makes that two roller spacings can free adjustment up and down.A gripper shoe has been installed at top at device, can put the Sheng slurry bucket that a bottom has exit passageway above, has settled the flow of a slide plate with the control slurry in the middle of exit passageway, thereby has satisfied the mesh base substrate of moulding different size size.

The utility model is introduced a deflector roll, by gear drive, and adopts the rubber that can stretch to bring transmission between deflector roll and lower roll between top roll and deflector roll, has realized that lower roll within the specific limits can be mobile continuously up and down.This has not only realized the relative motion of two rollers up and down, and has reached the adjustable purpose of two roller spacings up and down.This structure is simple especially, and is easy to manufacture and cost is low.And be provided with the Sheng slurry bucket that a kind of bottom has exit passageway at the top of device, this can make slurry flood organic foams and extrude these two processes of unnecessary slurry and realize synchronously, thereby has improved production efficiency.Slurry flow can be regulated by the slide plate of exit passageway, can satisfy the dip forming of the organic foam body of different size size.

Owing to adopt such scheme, that the improved pair roller pressurizing unit that the utility model provides has is simple in structure, easy to use, low cost of manufacture and the advantage that reduces labour intensity and enhance productivity.

Below in conjunction with example and accompanying drawing substantive distinguishing features of the present utility model is further described.

Fig. 1 is the front view according to a kind of improved pair roller pressurizing unit of the utility model design design.

1. contain the slurry bucket among the figure, 2. top roll, 3. device body frame, 4. vee-pulley, 5. gear, 6. deflector roll, 7. overfall groove, 8. lower roll, 9. slurry outlet passage, 10. slide plate

In Fig. 1, contain slurry bucket 1 and be positioned in the middle of the top support plate of device body frame 3, a slurry outlet passage 9 is arranged, in the middle of exit passageway 9, settled a slide plate 10 to be used to control the flow of slurry in its bottom.Top roll 2, deflector roll 6, lower roll 8 are installed in the medial surface of body frame 3, and gear 5, vee-pulley 4 are positioned at the body frame lateral surface, and overfall groove 7 is positioned on the crossbeam of device bottom, and it is to be used to reclaim the unnecessary slip of extrusion modling.Wherein deflector roll 6 one ends are equipped with vee-pulley 4, its other end is equipped with a combination wheel, this combination wheel is made up of gear 5 and vee-pulley 4, top roll 2 one ends are equipped with gear 5, lower roll 8 one ends are equipped with vee-pulley 4, and belt wheel 4 can cause that deflector roll 6 rotates, and gear 5 and belt wheel 4 can cause the rotation of top roll 2 and lower roll 8, that is top roll 2 and lower roll 8 be driven pulley, all makes its transmission by guide wheel 6.Specifically, deflector roll 6 and top roll 2 are by gear drive; Deflector roll 6 and lower roll 8 be by telescopic belt transmission, thereby realized that lower roll 8 can move up and down within the specific limits continuously, can be adjustable within the specific limits according to the thickness of required moulded products.Organic foam body with certain size is transported between the up-down rollers by deflector roll 6, mobile slide plate 10 makes the slurry of containing 1 li in slurry bucket flow on the organic foam through exit passageway 9, the relative motion of up-down rollers can make the organic foam body opposite side between two rollers that is soaked with slurry carry, the organic foam body is squeezed and gets rid of unnecessary slurry in this process, unnecessary slurry flows to overfall groove 7 simultaneously, can reuse.

The pair roller pressurizing unit of the utility model design not only makes organic foam body dipping sizing agent and extrudes unnecessary slurry two processes and carries out simultaneously, enhance productivity, and the flow of slurry can regulate easily by slide plate 10 again, till meeting the demands.
