Technical Field
The utility model relates to a feeding device, especially a feeding device is forced to spiral.
Background
The traditional roller type extrusion granulator is characterized in that materials freely fall between two rollers by means of gravity, and the materials move towards the direction with the minimum resistance due to the fluidity of the materials, and return upwards in the extrusion process, so that the extrusion granulation process has the advantages of small yield, low forming pressure, poor product quality and low production efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a feeding device is forced to spiral to overcome the defect that exists among the prior art.
The technical scheme of the utility model is that: a spiral forced feeding device is characterized in that: the device comprises a motor, a bearing seat, a blanking hopper cover, a connecting flange, a blanking hopper for storing materials, an extrusion screw, a support for supporting, a ventilation cap and an extrusion roller; the motor is connected with the lower hopper cover through a bearing seat and drives the extrusion screw to rotate through a connecting flange, the lower hopper cover is arranged on the lower hopper, the ventilation cap is connected to the lower hopper cover, and the squeeze roll is connected to the support.
The motor is a variable frequency motor.
The connecting flange is an adjustable connecting flange.

The technical effects of the utility model are that: the raw materials are uniformly and continuously added into the hopper from a feeding hole on the lower hopper cover, the motor drives the extrusion screw to input the materials between the two rollers, the materials reach a certain height and enter an extrusion angle, the materials are forcibly fed between the two rotating rollers, the two extrusion rollers rotate continuously, and the materials are extruded and molded. A pre-pressure is added above the materials to prevent the materials from moving upwards, and meanwhile, a downward extrusion force is applied to the materials through spiral extrusion, so that the extrusion pressure can be improved, the product quality is improved, and the production efficiency is greatly improved.
Drawings
The invention will be further explained with reference to the drawings of the embodiments:
fig. 1 is a schematic structural diagram of the present invention.
The reference numbers are as follows:
1. the device comprises a motor, 2. a bearing seat, 3. a blanking hopper cover, 4. a connecting flange, 5. a blanking hopper, 6. an extrusion screw, 7. a support, 8. a ventilation cap, 9. an extrusion roller and 10. materials.
Detailed Description
The utility model relates to a novel spiral force feed device, mainly used roll-type extrusion granulation shaping technical field. The powder material processed by the front end enters the blanking hopper 5 through the feeding hole on the blanking hopper cover 3. The variable frequency motor 1 drives the extrusion screw 6 to rotate through the adjustable connecting flange 4, and the materials 10 are extruded.
Referring to fig. 1, the specific structure of the present invention is:
a spiral forced feeding device comprises a motor 1, a bearing seat 2, a discharging hopper cover 3, a connecting flange 4, a discharging hopper 5 for storing materials, an extrusion spiral 6, a support 7 for supporting, a vent cap 8 and a squeeze roller 9; wherein,
the motor 1 is connected with the lower hopper cover 3 through a bearing seat 2 and drives the extrusion screw 6 to rotate through a connecting flange 4 to provide a forced downward extrusion force for the material 10 in the lower hopper 5,
the blanking hopper cover 3 is arranged on the blanking hopper 5 and used for supporting the bearing seat 2 and the motor 1,
the vent cap 8 is connected on the lower hopper cover 3 for ventilation and filtration,
the extrusion roller 9 is connected to the bracket 7 and is used for extruding and forming materials.
The utility model relates to a motor 1 can be inverter motor, can adjust spiral feed mechanism's rotational speed, according to the output of requirement, can select suitable motor speed, realizes the production automation.
The utility model relates to a flange 4 can be adjustable flange, the distance between adjustable screw extrusion face and the roll surface to adjust the extrusion intensity of roller to the material, improve product quality.
The utility model relates to an extrude spiral 6 and can adopt wear-resisting material whole casting to form, because helical blade is very easily worn and torn with the material looks mutual friction in extrusion process, so the spiral adopts whole casting, chooses for use the material that wear resistance is good, can improve the spiral life-span greatly. The extrusion screw is an important part of the forced feeding device, and the screw extrusion is adopted, so that the feeding speed is easy to control, the pressure angle is increased, the yield is increased, the slippage phenomenon of a bite area is reduced, and the production efficiency is greatly improved. Meanwhile, the materials can be partially degassed and compacted in advance in the forced feeding process, so that the product quality is greatly improved. In the examples, no details are given about the parts of the novel screw forced feeding device, which are commercially available or known.
