Abstract

The utility model discloses a counter-rotating extruding marble forming machine, which comprises two rotation wheels (3), wherein the two rotation wheels (3) rotate relative to each other, opening grooves or countersink grooves (1) are arranged on the rotation wheels at intervals, forming blocks (5) are arranged in the opening grooves and can swing or are arranged in the countersink grooves and can move, hemispheric grooves are arranged on outer end faces of the forming blocks, and the forming blocks can be combined into a whole between the rotation wheels. The forming blocks can expand and combine along the relative rotation of the rotation wheels to make a sphere, and the counter-rotating extruding marble forming machine is suitable for a flexible material, and is particularly suitable for wet powder to make the sphere. The counter-rotating extruding marble forming machine is compact in structure, and is convenient to manufacture and maintain, sphere production efficiency is high and sphere manufacturing cost is low, no dust is generated at an operation site, and environmental protection is facilitated.

Description

To changeing the extrusion modling marble forming machine

Technical field

The utility model relates to a kind of spheroid forming machine, especially relates to a kind of to changeing the extrusion modling marble forming machine.

Background technology

The processing unit (plant) of spheroid moulding has a lot, and the usefulness that has is milled, turning machine processing spheroid, and what have processes spheroid with casting pattern, and what have processes spheroid with injection, also useful impelling cooling processing spheroid etc.Such as; Through sintering or solidify microspheric form base (diameter is below 15 millimeters), mostly adopt and ward off a machine manufacturing, and mostly adopt hydraulic pressure extruding manufacturing with the medium-and-large-sized spheroid (diameter is more than 15 millimeters) of powder or plastic material processing with the powder moulding; Adopt hydraulic pressure extrusion modling processing spheroid; The one, the hydraulic test expense is bigger, and the 2nd, mould structure is had relatively high expectations than complicacy and material, and the spheroid manufacturing cost is higher; Be to utilize that powder extrusion process ball material waste is big, the production site dust is many again, environmental pollution produces infringement to human body.

The utility model content

The problem that exists in making to big-and-middle-sized spheroid in the above-mentioned prior art, the utility model provide a kind of big-and-middle-sized spheroid not only make efficient height but also low cost of manufacture to changeing the extrusion modling marble forming machine.

The technical scheme that the technical problem that the utility model will solve is taked is: saidly comprise two counterrotating runners to changeing the extrusion modling marble forming machine; Be arranged at intervals with open slot or counterbore groove on the said runner; In open slot, be provided with and swing or in the counterbore groove, be provided with movably forming blocks; Said forming blocks outer face is provided with hemispheric groove, and said forming blocks is capable of being combined being integral between runner.

The utility model technical scheme specifically has two kinds; A kind of is to adopt the inner activity of forming blocks to be fixed in the open slot on the runner; Forming blocks can be swung up and down in the runner rotation synchronously, thereby two forming blocks outer faces ability symmetry in the runner rotary course is inclined upwardly open charging, horizontal combination is carried out ball under extrusion modling and the downward symmetrical inclination opening to material; Another kind is that forming blocks is movably set with in the counterbore groove; But forming blocks synchronization telescope in the runner rotation is moved, thereby two forming blocks outer faces ability symmetry in the runner rotary course is inclined upwardly open charging, horizontal combination is carried out ball under extrusion modling and the downward symmetrical inclination opening to material.

The utility model forming blocks outer end can be applicable to flexible material through opening each other and making up and make spheroid when rotating with two relative runners, and the powder-material that particularly is suitable for hygrometric state is made spheroid.The utility model not only compact conformation, make easy to maintenance, and spheroid to make production efficiency high, the spheroid low cost of manufacture, the no dust in operation ground helps environmental protection.

The specific embodiment

Embodiment 1, in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, earlier powder processed wet feed (having certain viscosity), and wet feed quantitatively joins in the forming blocks through meter.Saidly comprise two counterrotating runners 3 (rotation of left side runner up time, the rotation of the right runner inverse time) to changeing the extrusion modling marble forming machine; Runner is arranged on the frame with rotating shaft 7, and rotating shaft is arranged at intervals with three open slots 1 by driven by motor on said every runner; Said open slot cross section is trapezoidal; In open slot, be provided with forming blocks 5, said forming blocks is cuboid, and forming blocks is inner to link to each other with runner with spring 2 with bearing pin 6; That the forming blocks outer end is is cantilever-shaped, this cantilever end face is provided with hemispheric groove, and said forming blocks is capable of being combined being integral between runner.Make two runners relative to rotating synchronously through electrical equipment control, under spring action, forming blocks is near open slot one side; When forming blocks rotates to the hopper position with runner,, this end top is opened each other can form a spherical cavity (as shown in Figure 3) because (band groove one end) bottom, forming blocks outer end mutual extruding, spring downwards are stretched; At this moment, hopper 4 metering blankings, wet feed 8 gets in the formed spherical hollow space of two forming blocks grooves; When the forming blocks continuation rotated to horizontal level with runner, two forming blocks were combined to form one, in being integrally formed, wet feed are squeezed into spheroid 9 (as shown in Figure 1); Forming blocks continues to rotate with runner; Spring continue to stretch, and open bottom, two forming blocks outer ends, the spheroid free-falling (as shown in Figure 4) of moulding and receive through manipulator after be transported on the moving defeated machine of belt.Behind the following ball, forming blocks automatically restores to original position and continues rotary work with runner under spring action, thereby can constantly accomplish the manufacturing of spheroid.Forming blocks also is arranged to four, five, six etc.

Embodiment 2, and in Fig. 5, embodiment 2 is described to changeing the extrusion modling marble forming machine except that following part is different with embodiment 1 structure, and other structure is identical with embodiment 1 with the course of work.The structure difference is: be arranged at intervals with three counterbore grooves 1 on said every runner; Said counterbore groove is a deep hole, in the counterbore groove, is provided with forming blocks 5, and said forming blocks is the cylinder bodily form; Said forming blocks is inner to link to each other with runner with being slidingly matched with spring 2; Be that forming blocks and counterbore groove are and are slidingly matched, forming blocks is inner to be connected on the runner with spring 2, and that the forming blocks outer end is is cantilever-shaped, this cantilever end face is provided with hemispheric groove; When forming blocks was drawn close extruding each other, the mutual telescopic moving of forming blocks also was combined into one between runner.
