Abstract
The utility model discloses a feeding device of a rubber pelletizer. Two conical feeding screw rods are positioned at the bottom of a feeding hopper; an output shaft of a speed reducer is rigidly connected with the root of one of the two conical feeding screw rods; the root of the conical feeding screw rod is fixed inside a case by virtue of a bearing; the root of the other conical feeding screw rod is fixed inside the case by virtue of a bearing; a circular truncated conical gear A and a circular truncated conical gear B which are meshed with each other are further fixed at the roots of the conical feeding screw rods; the two conical feeding screw rods are tightly adhered to each other and tilt downwards to a discharge hole; threads in the conical feeding screw rods are meshed with each other; the tail ends of the conical feeding screw rods are positioned at a discharge hole in the bottom of the feeding hopper. By adopting the feeding device, refined blocky rubber can be compulsively pushed into a cylinder above double screw rods of a main extruder, the feeding amount is large, the pressure is large, the feeding speed is high, the material feeding is smooth, and the production efficiency of the extruder is greatly improved.
Description
Technical field
The utility model relates to a kind of drawing-in device of rubber comminutor.
Background technology
Rubber material comminutor is that the rubber after mixed refining process is added from hopper, and through further compression, extrude particle screening after mixing and become the plant equipment of finished granule, it is the key equipment of rubber-like material granulation, is widely used in chemical field.
The feeding of existing comminutor is due to the effective L D ratio increasing of parallel twin-screw granulation in the same way and the screw-rod structure of equidirectional rotation, in the mixing rear pan feeding problem that has bulk rubber, (1) because rubber is workshop temperature in charging aperture place temperature, there is higher elasticity, often above feeding roller and screw rod feeding section, rolling is difficult for entering screw channel, make feeding ability inadequate, reduce extrusion capacity; (2) effect of feeding roller is that rubber is pressed into screw channel, but because of spout place narrow dimension, the pressure that rubber is produced presses to rubber feeding roller both sides simultaneously, may enter feeding roller bearing, finally makes bearing failure; (3) bulk rubber is all to be sent into from the side by feed roller in the charging aperture of twin-screw cylinder initiating terminal by hopper; the sizing material entering can only contact a screw rod, then by the rotation of this screw rod, it is entered between two screw rods, because the viscosity of sizing material is large; this enter material way feeding capacity is little; pressure is little, and the speed entering is slow, and sizing material is easily piled up at charging aperture place; charging aperture is stopped up; have to take apart the equipment that charging aperture goes out and clear up, its cleaning is loaded down with trivial details, affects the efficiency of comminutor.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, and a kind of drawing-in device of rubber comminutor is provided, and this drawing-in device feeding capacity is large, and pressure is large, and feeding is smooth and easy.
For achieving the above object, technical solution of the present utility model is: a kind of drawing-in device of rubber comminutor, and it comprises support, motor, reductor and feeding hopper that support is provided with are positioned at two conical feed screws of feeding hopper bottom; The root of one in the output shaft of reductor and two conical feed screws is rigidly connected, the root of the conical feed screw of this root is fixed in cabinet by bearing, the root of the conical feed screw of another root is by the fixing cabinet of another bearing, and the root of two conical feed screws is also fixed with intermeshing circular platform type gear A and circular platform type gear B; Two conical feed screws are close to mutually, and downward-sloping to discharging opening, and the screw thread on it is intermeshing, and end is positioned at the discharging opening place of feeding hopper bottom.
When work, driven by motor circular platform type gear A and the reverse rotation of circular platform type gear B, thereby drive two feed screw reverse rotations, bulk rubber the refinery that makes to enter from feeding hopper top is compression the discharging opening propelling to feeding hopper further, forces in the machine barrel of the twin-screw top that pushes main extruder; Drawing-in device of the present utility model adopts the double-cone feeding under being tilted to, and its feeding pressure is large, and sizing material no longer enters feeding roller bearing, has avoided the generation of bearing failure phenomenon; And sizing material is pressed into twin-screw by side direction and changes into from twin-screw top and being pressed into, and contacts with two screw rods simultaneously, and two screw rods advance material simultaneously in twin-screw cylinder, have improved rate of feeding; Its feeding capacity is large, and pressure is large, and feeding is smooth and easy; Greatly improve the production efficiency of extruder.

Fig. 2 is the vertical view cutaway drawing that the utility model is removed cabinet upper plate.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As depicted in figs. 1 and 2, the present embodiment comprises support, and motor 9, reductor 8 and feeding hopper 2 that support is provided with are positioned at two conical feed screws 4 of feeding hopper 2 bottoms.The root of one in the output shaft 7 of reductor 8 and two conical feed screws 4 is rigidly connected, the root of the conical feed screw 4 of this root is fixed in cabinet by bearing 6, the root of the conical feed screw 4 of another root is fixed in cabinet by another bearing 10, and the root of two conical feed screws 4 is also fixed with intermeshing circular platform type gear A 5 and circular platform type gear B 11.Two conical feed screws 4 are close to mutually, and downward-sloping to discharging opening 1, and the screw thread 3 on it is intermeshing, and end is positioned at discharging opening 1 place of feeding hopper 2 bottoms.The output shaft 7 of described reductor 8 is rigidly connected by the root of in Hooks coupling universal coupling and two conical feed screws 4.
Above-described embodiment is only preferred and exemplary, and those skilled in the art can carry out equivalent technologies improvement as required, and it is all covered by the protection domain of this patent.
