Abstract
The invention discloses a novel double-screw extruder which comprises a power device, a speed reducer connected with the power device, a transmission mechanism connected with the speed reducer, a sleeve connected with the transmission mechanism, lead screws arranged in the sleeve, a machine head arranged at the top end of the sleeve, a hopper arranged on the sleeve, support frames arranged on the sleeve at equal intervals, and a material barrel arranged on the ground, wherein a runner for communicating the hopper with the sleeve is arranged in the hopper and is internally provided with a feeding lead screw, and the lead screws are in transmission connection with the transmission mechanism. Materials are transmitted to the hopper through a conveying device, compacted through the feeding lead screw in the runner, discharged into the lead screws through a filter net, and extruded by a forming mould in the machine head through the first lead screw and the second lead screw. The novel double-screw extruder has the advantages of simple structure and high working efficiency, and avoids phenomena of nonuniform material conveying and sleeve shaking.
Description
Technical field

Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly to be had simple in structurely, and high efficiency has been avoided the Novel double-screw extruder of phenomenon of the inhomogeneous phenomenon of mass transport and sleeve vibrations.
the present invention is achieved through the following technical solutions: a kind of Novel double-screw extruder, comprise power set, and the reductor that is connected with power set, and the transmission mechanism that is connected with reductor, and the sleeve that is connected with transmission mechanism, and be arranged on screw rod in sleeve, and be arranged on the head on sleeve top, and be arranged on hopper on sleeve, and be equally spaced and be arranged on bracing frame on sleeve, and be arranged on ground material barrel, be provided with the runner that is communicated with hopper and sleeve in described hopper, in described runner, feed worm is installed, described screw rod and transmission mechanism adopt and are in transmission connection.
As preferably, described screw rod comprises the first screw rod and the second screw rod, and the first screw rod and the second screw rod adopt screw thread staggered and install side by side.
As preferably, support frame as described above has more than one, bracing frame comprises upper junction plate, lower connecting plate and base, the described upper junction plate left and right sides is provided with the first fixed block, the described lower connecting plate left and right sides is provided with the second fixed block, described lower connecting plate is fixedly connected with base, and described upper junction plate and lower connecting plate coordinate to be installed, and adopts studs pass through the first fixed block and be connected the fixed block connection.
As preferably, be provided with feeding device between described hopper and material barrel.
As preferably, be provided with mould in described head, and mould is connected with screw tip.
As preferably, described runner bottom is provided with screen pack, and described screen pack adopts fillet to connect.
The invention has the beneficial effects as follows: the first, adopted feed worm, therefore avoided the inhomogeneous phenomenon of conveying to occur, improved the qualification rate of product;
The second, adopted a plurality of bracing frames, reduced the vibrations of sleeve, therefore improved the qualification rate of product;
The 3rd, adopted feeding device, the work that has reduced the operator is powerful, has improved working (machining) efficiency;
The 4th, screen pack adopts fillet to connect, and has prevented that the situation of traditional filter screen right angle connection stacking material from occuring.
