Abstract
The utility model discloses a material conveying screw rod mechanism, which comprises a material conveying screw rod, a machine tube, a material feeding hopper and a transmission device. The utility model is characterized in that a vacuum interface is arranged on the tube wall of the machine tube, a filter plate and a press plate are embedded inside and outside the vacuum interface, and a vacuum joint is inserted and connected on the press plate. The material conveying mechanism of the utility model thoroughly solves the problem of desaeration of powdery materials, improves the material conveying effect, and enhances the material conveying pushing force, so the defects of low density and nonuniform density of sheets pressed by the existing dry pelleting machine and the defects of low yield, poor granule density, nonuniform granule density, low harvesting rate and the like when the existing dry pelleting machine is used for pressing loose materials can be overcome, the structure is reasonable, and the material conveying screw rod mechanism is worth of being popularized.
Description
Technical field
The utility model relates to the Drygranulatemachine technical field, is meant a kind of feeding spiro rod mechanism especially.
Background technology
Feeding spiro rod mechanism is the critical component of Drygranulatemachine, is widely used in industries such as pharmacy, food, chemical industry at present.At present; generally adopt the conical feeding spiro rod of variable pitch; in the course of conveying of material; though the conical feeding spiro rod of variable pitch can partly be sloughed the air that contains in the dry powder; but this air is discharged along screw rod appearance and machine tube inner wall gap; influenced the conveying effect of material; reduced the propulsive force that material enters mill roll mechanism, shortcomings such as causing that the Drygranulatemachine that is mated exists that pressure-formed slice, thin piece density is low, yield poorly when density unevenness and compacting bulk material, grain density is poor, grain density is inhomogeneous, yield rate is low.
Summary of the invention
The feeding spiro rod mechanism that provides a kind of air that dry powder can be contained to slough is provided the purpose of this utility model.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of feeding spiro rod mechanism comprises feeding spiro rod, machine barrel, loading hopper and driving device, it is characterized in that: offer vacuum interface on the described machine barrel barrel, be equipped with screen plate and pressing plate inside and outside the vacuum interface, be plugged with vacuum adapter on the pressing plate.
As further specifying, between screen plate, pressing plate and machine barrel, form an enclosure space.Vacuum pump is connected with vacuum adapter, makes to produce vacuum in this space, thereby the air in the dry powder is discharged through filter plate, and the dry powder after the degassing carries out compressing tablet with screw rod transmission to next mechanism.
The utility model feed mechanism has thoroughly solved the degassing problem of powder; improved the conveying effect of material; strengthened the mass transport propulsive force, thereby overcome that the pressure-formed slice, thin piece density of existing Drygranulatemachine is low, yield poorly when density unevenness and compacting bulk material, shortcoming such as grain density is poor, grain density is inhomogeneous, yield rate is low.
Description of drawings
Fig. 1 is the utility model example structure scheme drawing.
Label among the figure is: 1, vacuum adapter; 2, pressing plate; 3, screen plate; 4, machine barrel; 41 vacuum interfaces; 5, feeding spiro rod; 6, support; 7, loading hopper; 8, driving device.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
As Fig. 1, the utility model is an a kind of feeding spiro rod mechanism.Mainly form by the outer machine barrel 4 of feeding spiro rod 5, screw rod, loading hopper 7 on the machine barrel 4 and the driving device 8 of screw rod 5 one ends etc.On the barrel at machine barrel 4 rear portions, offer two vacuum interfaces 41, and be symmetrical arranged up and down.Described vacuum interface 41 is square.Vacuum interface 41 inside and outside orders are equipped with screen plate 3 and pressing plate 2.Outer ply wood 2 usefulness screws and machine barrel 4 barrel sealing and fixing.Be plugged with vacuum adapter 1 on the pressing plate 2.Vacuum adapter 1 is connected with vacuum pump.Whole feed mechanism is installed on the support 6.
